Sullair Drive Repair

Sullair drive repair has over the past decade become a cost-efficient way to reduce drive replacement costs while extending the overall lifetime of Sullair drive products. Today manufacturers around the globe within a wide range of industries are finding more ways to apply drives to their rotating equipment. From past experience, smaller horsepower drives typically fail in eight years and are more often replaced rather than repaired. Larger horsepower drives last longer by virtue of repairs that often require replacement of circuit boards and other electrical components. After bearing the cost of two or three replacement boards in any one VFD drive, the user often realizes that the drive should have been junked sooner.

Sullair drive repair is common for Sullair service centers, manufacturers, and others using Sullair drive products. Sullair drive repair is preferred by Sullair service centers and other Sullair drive users because Sullair product replacement is more expensive than drive repair. Most industrial manufacturing repair centers do not have the capabilities to offer Sullair drive repair, and that creates few alternatives for Sullair drive users who experience drive failure and drive faults. Sullair offers repair services for their drives with extensive lead times at premium pricing and most Sullair drive users cannot afford downtime with extensive lead times nor do these users prefer to pay premium repair prices.

Precision Electric saves Sullair drive users thousands of dollars by repairing failed Sullair drives. Precision Electric has also saved Sullair drive users in downtime by repairing Sullair drives in less time than it would have taken Sullair to replace a non-stock drive. Sullair drive repair is an asset to manufacturers and others who use Sullair drive products. Precision Electric uses the most advanced testing equipment for all Sullair drive repair, and Precision Electric repair technicians have hundreds of years of combined experience in testing and replacing Sullair drive components.

Nema Enclosure Ratings and IEC Protection Codes

There are two widely used standards for enclosure ratings. Nema enclosure ratings were created as the national standard for enclosures in the United States. Nema enclosure ratings were established by NEMA (National Electric Manufacturer Association). The international standard for enclosures was established by IEC (International Electric Codes).Below are the standard Nema enclosure ratings for electrical equipment and IEC codes; both showing each of their descriptions. Manufacturers tend to offer electrical equipment in a number of different Nema and IEC enclosure ratings for safe operation in various environments. In todays international trade world, both standards are widely mentioned on a single product. (Example: NEMA 4X / IP 65). The most common Nema standards followed by IEC codes are shown below:Nema Enclosure Ratings Type 1 are constructed for indoor use to provide a degree of protection to personnel against access tohazardous parts and to provide a degree of protection of the equipment inside the enclosure against ingressof solid foreign objects (falling dirt).Nema Enclosure Ratings Type 12are constructed (without knockouts) for indoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosureagainst ingress of solid foreign objects (falling dirt and circulating dust, lint, fibers, and flyings); to pr ovide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (drippingand light splashing) and to provide a degree of protection against light splashing and seepage of oil and noncorrosive coolants.Nema Enclosure Ratings Type 3R are constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure againstingress of solid foreign objects (falling dirt); to pr ovide a degree of protection with respect to harmful effectson the equipment due to the ingress of water (rain, sleet, snow); and, that will be undamaged by the externalformation of ice on the enclosure.Nema Enclosure Ratings Type 3RXare constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid for eign objects (falling dirt); to pr ovide a degree of protection with respect to harmful ef fectson the equipment due to the ingress of water (rain, sleet, snow); that will be undamaged by the externalformation of ice on the enclosure that provides an increased level of protection against corrosion.Nema Enclosure Ratings Type 4are constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure againstingress of solid foreign objects (falling dirt and windblown dust); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow, splashing water, and hosedirected water); and, that will be undamaged by the external formation of ice on the enclosure.Nema Enclosure Ratings Type 4Xare constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure againstingress of solid foreign objects (falling dirt and windblown dust); to provide a degree of protection with respectto harmful effects on the equipment due to the ingress of water (rain, sleet, snow, splashing water, and hose directed water); that provides an increased level of protection against corrosion; and that will be undamaged by the external formation of ice on the enclosure.IP Codes – IEC RatingsIEC outlines an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, fingers, dust) and moisture. This classification utilizes the letters IP (Ingress Protection) followed by two digits (example: IP 64).          The first digit indicates the degree that persons are protected against contact with moving parts (other than rotating shafts) and the degree that equipment is protected against solid bodies intruding into an enclosure.The second digit indicates the degree of protection of the equipment inside the enclosure against harmful entry of various forms of moisture (i.e. submersion, dripping, spraying).To learn more about Nema enclosure ratings, visit either the Nema Websiteor IEC Website.

Robotic Automation: ABB Robots For The Packaging Industry

Robotic Automation: ABB Robots For The Packaging Industry

ABB robotic automation ensures shorter product life cycles, new packaging designs, product variants and batch manufacturing. Compared to dedicated hard automation, robot lines are shorter and allow far better utilization of floor space. In addition to increased up-time and total throughput of production, fewer accidents and increasingly demanding workplace laws are compelling reasons to make the transition to ABB robotic automation. Robots are usually associated with handling repetitive tasks in a process either in high volume production roles or where flexible handling systems are needed for frequent changes. In the packaging industry, robots generally fall into three main areas: 

  • Pick and Place Applications (where products are packed into trays or secondary packages)
  • Feed Placement (where products are prearranged on a conveyor to ease future packaging procedures)
  • Palletizing (pallet loading and unloading)

 PickingThis is an area in which ABB services a multitude of products, applications and packaging line set-ups. Frozen food, bakery and confectionery, ice cream, meat and fish, cheese, pet food, medical products, shampoo and perfume bottles are a few examples. The ABB IRB 360 is the first 2nd generation delta robot; The FlexPickerTM . The new robot family will initially see three models available. Stainless steel versions are available for wash down duties such as in meat and dairy handling applications. Apart from even greater performance, the new delta robot has a significantly increased payload of up to 3 kg opening up further application possibilities, especially at the end of line. For full 6-axis flexibility, less demanding cycle times and payloads of up to 5 kg, ABB recommends the IRB 140.PalletizingPlacing boxes, trays, bags, bottles or other items on a pallet seems easy enough. But, when youre dealing with the rigorous demands of multiple feeder lines, quick box-pattern changes and high up-time, nothing compares to ABB robotic automation. The ABB IRB 660 has the versatility, reach and handling capacity needed for most palletizing applications. For even greater payload requirements, ABB standard 6-axis robots are the largest and are built to handle as much as 1,433 lbs.The IRB 660 is a refinement of the well established, proven, ABB IRB 640 palletizer, with more than 1,800 installations worldwide. The new version of this robot blends speed, reach and payload like no other. Exceptionally fast, this 4-axis performer combines a 3.15 meter reach with a 250 kg payload, making it ideal for palletizing bags, boxes, crates, bottles and more. The new palletizer comes in two versions; a high throughput version designed for 250 kg and a high-speed version built to handle 180 kg payloads at full speed. The IRB 660 has the versatility, reach and handling capacity to meet the demands of just about any palletizing application. And its robust enough to perform steadily in the toughest environments.Tailor Made Robots For Demanding Packaging IndustriesABB robotic automation includes specialized robots for picking, packing and palletizing. In addition, ABB provides a wide range of standard 6-axis robots which allows customers to meet the demands of nearly all applications in the packaging industry. Whats more, ABBs unique packaging software, including vision technology and conveyor tracking, facilitates continuous production flows and packing on-the-fly. This allows for efficient handling of food and beverages, pharmaceuticals, cosmetics, electronics or personal care products.High Speed PackingThe ABB FlexPicker IRB 360 is a unique parallel-arm robot designed for the most exacting high-speed picking and packing applications. The new robot succeeds ABBs widely used FlexPickerTM IRB 340 system and is the result of 10 years experience and research and development combined with proven packaging technology. ABB has over 2000 delta robots installed globally and is the leader in this state of the art picking and packing technology. The newest version of the IRB 340 is called the FlexPickerTM IRB 360.Cost Efficient PackingThe 4-axis IRB 260 houses all the necessary features for placing items in boxes, tray handling and more. Optimized for packing applications this robot can work closely to its own base, allowing very compact packing cells and integration into tight packing machines. IRB 260features a 30 kg payload capacity and short cycle times to meet the packing industry requirements. Like all ABB robots, the IRB 260 is compatible with PickMaster, our dedicated software for packaging applications, including vision guidance and easy programming.Food Safety & PharmaceuticalABB builds robots to meet the most demanding work conditions as well as the highest hygiene standards. In addition, all ABB robots are IP67 certified, ensuring tightly sealed joints and connectors. The IRB 360, which is most likely to handle open food, is available in wash-down and stainless steel and is IP69K certified.The demands on quality validation and traceability are extremely high in pharmaceutical production. The absolute accuracy, repeatability and high up-time of ABB robots result in massive improvements over manual operation or dedicated production equipment. All ABB smaller robots are suited to primary packing and are verified for clean-room operation.To learn more about ABB Robotic Automation, visit the ABB Website.

Inverter Repair

Most inverterrepair can be prevented with routine maintenance. Inverter repair costs and lead times can also be reduced with routine maintenance. Inverterrepair can be expensive and also cost manufacturers production downtime while the inverter repair is in process.Most manufacturers stock spare inverter modulesto prevent production downtime in the event of an inverter failure.Components used forinverter modules are often cheaply made and prone to failure. Knowledgeable inverter repair shops should replace cheaply made components with high quality components during the inverter repair process. Using high quality components in an inverter repair ensures a higher chance of success and a longer lifespan during production.ConnectionsCheckingconnections is a step many people miss or do incorrectly during the inverterrepair process. Heat cycles and mechanical vibration can lead to sub-standard connections, as can standard preventative maintenancepractices. Reusing torque screws is not a good Idea, and further tightening an already tight connection can ruin the connection.Bad connections eventually lead to arcing. Arcing at the inverterinput could result in nuisance over voltage faults, clearing of input fuses, or damage to protective components. Arcing at the inverteroutput could result in over-current faults or even damage to the power components.Loose connections can cause erratic operation. Loose START/STOP signal wires can cause uncontrollable inverterstarting and stopping. A loose speed reference wire can cause the drive speed to fluctuate, resulting in scrap, machine damage, or personnel injury.Conduct Diode and IGBT TestsThere are a number of methods to test the input and output power sections of an inverter, and this step is essential prior to applying power to the inverterunit. If for any reason there is a short on the input side or output side of the inverter, further damage can be caused to the unit if power is applied to it.For this reason, Precision Electric uses meters to properly test the input and output power sections of the inverter prior to applying power to the actual unit. If a short is found, the unit can be disassembled and the cause of the short can be diagnosed and quoted for repair. If the repair is too costly, then a replacement is offeredto the customer.Power Up UnitIf the input and output power sections test healthy during this step of the inverter repair process, Precision Electric will power the unit and perform amp reading and output frequency tests. Precision Electric prefers to slowly increase power voltage to the unit until the rated input voltage of the inverter is achieved.Depending on whether or not the inverter provides a display will determine what further action(s) will be taken. If display is unavailable, dis-assembly and diagnosis of the internal power supply of the control section of the inverter is likely necessary to further evaluate cause of failure and establish costand lead time for the inverter repair.Run A MotorIf the previous three tests have passed during the inverter repair process, then it is time to run a basic jog function of the inverter with a simple template program. Often when an inverter comes into our facility, we make sure to backup whatever program is currently stored in the inverterprior to inputting a template program and running a test procedure. This ensure we have a backup copy of the program.The best method for backing up depends on the brand of drive, but after it has been backed up, we either reset the inverterto factory defaults through the keypad and recommission a basic start, stop and job application or closed loop if an encoder is involved. If the motor will not run, it will be necessary to checkthe output voltages and current ratings going to the motor to see if the inverteris functioning properly to rotate the motor.Contact CustomerAt this point we have determined the cause of failure, estimated lead time and costof the inverterrepair. If the inverter has tested good entirely, then further underlying issues are communicated with the customer. This is when Precision Electricwill gather application specific information from the customer to establish whether or not it may be some outside issue associated with the system including, but not limited to, PLC communications, faulty IO, bad wiring or even bad cabling. There is no single way to do this step, as it really depends on a wide variety of variables.Send Service TechIf the customer cannot establish failure on any other aspect of the machine and the inverterappears to test fine, then it may be necessary to send a field service technician on site to establish cause of failure. Field service technicians should betrained to troubleshoot any issue ranging from standard inverterrepair, to advanced robotics, PLCs and more. Field technicians should also be trained to establish cause of failure and come up with solutions as quick as possible.Inverter repair should be taken with extreme caution. Inverterrepair should only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends to consult an expert in the field when repairing or installinginverterequipment.Many invertercontrollers have an internal DC bus that retains a charge after power has been cut to the drive, as a result, it does not mean it’s safe to work with. Technicians working with inverter repair must always take extra precautions to ensure proper safety measures are taken, or injury or even death may occur.For inverterrepair and inverter replacement quotes, contact Precision Electric.

VFD Drives

VFD drives are known as Variable Frequency Drives. VFD drives are also known as variable speed drives (VSDs), adjustable speed drives, motor speed controllers and inverters. VFD drivesare solid state controllers used in AC or DC electric motor applications. Most VFD drives are applied on alternating current (AC) electric motors in the industrial manufacturing world. There are some direct current (DC) electric motor applications that apply variable frequency drives, but most manufacturers seek AC motors because DC motors are expensive and they’re more prone to failure. VFD drives can also be used as a phase converters when three phase motors need to be operated from single phase power.VFDdrives areused in mills, lathes, fans, air compressors, pumps, conveyors, welders, robots and many other electric motor applications to control the speed regulation of an electric motor. Over 30 percent of the world’s electrical energy is consumed by electric motors in fixed-speed fan, pump, and air compressor applications. The basic idea for using a VFD on mills, air compressors, and fans is to decreasethe amount of electrical energy being consumed toreduce electricity costs.Energy SavingsOnly about3% of the total installed AC electric motors in the United States use VFDdrives.An estimated 60-65% of electrical energy in the United States is used to supply electric motors, and 75% of that electrical energy is consumed by fan, pump and air compressor applications.Approximately 18% of the electrical energy used in the 40 million motors in the United States could save power consumption via efficient energy improvement by using VFD drives on these electric motor applications.Performance and OperationVFDdrives are applied to alternating current (AC) electric motors to increase quality control and reduce energy consumption during the process of manufacturing.VFD drives increase quality control by monitoring the electric motor speed, pressure, temperature, torque, and tension; and then adjusting the motor to operate as economical as possible to meet the VFDcriteria.Fixed-speed electric motor loads exposethe electric motor to high starting torque and electrical current surges that are up to eight times the full-load motor current. When VFDdrives are used on an electric motor, the VFDgradually ramps the electric motor up to full load operating speed; this decreases mechanical and electrical stress, which minimizes motor maintenance and motor repair costs which extends the life of the electric motor and manufacturing equipment.VFD drives haveunique programming capabilities that allow for application specific patterns to minimize electrical and mechanical stress on electric motors during operation. Every VFD drive manufacturer uses a unique parameter selection designed so that every manufacturing field has VFD products designed for their industry.Repair and ReplacementVFD repair should be taken with extreme caution. VFD repair should only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends to consult an expert in the field when repairing VFD equipment.Many VFD controllers have an internal DC bus that retains a charge after power has been cut to the drive, as a result, it does not mean it’s safe to work with. Technicians working with VFD repair must always take extra precautions to ensure proper safety measures are taken, or injury or even death may occur.Precision Electric offers free repair quotes and offers 24 hour emergency repair services. Repair services performed by Precision Electric include anin-service 12 month warranty; the Precision Electric in-service warranty begins the day repaired work is installed and put into service.To learn more about VFD drives or for VFD repair and replacement, contact Precision Electric.

SVX9000 VFD Repair AndTroubleshooting

VFD failure is a common problem among Eaton VFDusers. VFD failure is mainly caused from equipment reaching the end of its life cycle orneglecting routinemaintenance.SVX9000 VFD repair can be repaired by Eaton Corporation but EatonCorporationtakes a long time to diagnose and repair their own equipment. Most of the time Eaton will hold onto a manufacturers VFDfor months and then tell them that the drive must be replaced because it cant be repaired.

Plastic Processing Machinery

Plastic injection molding is a manufacturing process for producing parts by injecting material into a mold. Plastic processing machinery and plastic extrusion machinery are used in plastic injection molding industries. After100 years of development, plastic extrusion has gonefrom single screw to twin-screw, multiple screw (or no screw) to other more advanced processes. Plastic processing machinery requires versatility and precision. Through customized solutions, ABB plastic processing machinery is offered in a complete range of packages that include AC and DC motors, drives, controls and engineered safety features.ExtrudersSpecific AC and DC motor and drive solutions can be applied dependent on the type of end plastic product being produced as well as the type and size of the extruder. Motor types typically used include AC induction (enclosed or laminated frame designs), DC, servo or permanent magnet. Variable speed drives are used for precise motor control and increased energy efficiency, as well as for environmental and cost reasons. Drives also provide dynamic torque limit for protection of the extrusion screw without speed or position feedback devices, resulting in lower initial investment and installation costs and higher operational reliability. Downstream machinery: Various types of downstream machinery may be present to facilitate necessary cooling, take-off and/ or other discrete handling of the extruded material, such as cut-to-length, slitting, stacking, coiling, etc. These are in general typical drive applications requiring drive performance characteristics ranging from speed or torque regulation to simple motor control.Processes Of EquipmentAmelt pump is fed by a speed-regulated, pressure-controlled extruder which provides precise control of the molten plastic output flow, optimizing the consistency of the flow delivery rate. Precise tension control is vital for plastic film processing. The superior speed regulation of ABB drives maintains the tension within the established limits and the fast, accurate drive-to-drive line speed communication provides precise synchronization of take-off roll sets.Film must be wound under constant tension, requiring torque regulation of the winder motor, which must continually adapt to ever-changing roll diameters. This can be achieved either by using an ABB drive with winder software or integrating a separate PLC into the control system.ABBs dynamic control of asynchronous and PM servo motors enables the rapid correction of load-side disturbances. ABB drives with direct torque control (DTC) provide speed and torque control without sensors.ABB plastic processing offers a full complement of products and technologies for design and delivery of solutions tailored to meet individual needs and optimize investment returns.ABB plastic processing machinery is designed by vast global experience gained from many decades of implementing motors, drives, controls and complete systems across a wide variety of extrusion types including: sheet extrusion, film extrusion, blown film, coating, tube/hose/pipe, co-extrusion and compound extrusion.

Food And Beverage Manufacturing

Modern food and beverage manufacturing from the 19th and 20th centuries began mainly to serve military needs. In 1809 Nicolas Appert invented anairtight bottling technique used to preserve food for French troops that contributed to the development of tinning, followed by canning by Peter Durandin 1810. Canning was expensive and hazardous because lead was used in cans but later became a standard around the world. Louis Pasteur discoveredPasteurization in 1864; this process improved the quality of preserved foods and was introduced to preserve wine, beer, and milk preservation.In western Europe and North America, the second half of the 20th century witnessed a rise in the pursuit of convenience. Food processing companies inwestern Europe and North America marketed their products during the second half of the 20th century to middle class working wives and mothers. Frozenfoods were a sales success in juice concentrates and TV dinners. Food and beverage manufacturing utilized the value of time to appeal to the postwarpopulation and today, this same appeal contributes to the success of convenience foods.

Benefits And Risks Of Food And Beverage Manufacturing

The benefits of food and beverage manufacturing today is the removal of toxins, preservation, increased food consistency, andsimple marketing & distribution.Food and beverage manufacturing also increases yearly availability of many foods, allows for transportation of perishable foods across longdistances and makes many foods safe to eat by removing micro organisms that cause spoiling. Modern grocery stores only exist as a direct resuld of modernfood and beverage manufacturing techniques. Modern food and beverage manufacturing techniques are also credited for transportation food and beverageproducts across long distances. Modern food and beverage manufacturing techniques also play a role in the improvement of the quality of life for peoplewith allergies, diabetics, and other people who cannot consume some common foods.All processing of food affects its nutritional density. The amount of lost nutrients will depend on the food and processing methods.Using food additives raises another safety concern; the health risks of any additive will vary from person to person; take for example using sugar as afood additive could affect persons with diabetes. Certain additives can also result in addiction to particular foods. As these effects are discovered,laws are changed to regulate these issues and practices constantly change to make food and beverage manufacturing safer.Food and beverage manufacturing is a mechanical process that utilizes mixing, chopping, grinding, and integration of equipment in the production process.These processes do introduce a number of potential contamination risks. As mixing bowls or grinders are used over long periods of time, the food contact parts will eventually fracture and fail. This type of failure introduces brings small and large metal contaminants into the production line. Continuing food and beverage manufacturing with these metal fragments can result in equipment failure and the risk of ingestion by consumers. Food and beverage manufacturers utilize industrial-grade metal detectors to automatically locate and reject any metal fragments during production. Large food and beverage manufacturing processors utilize several metal detectors within the production line to prevent consumer health risks and reduce the damage of industrial equipment.To learn more about food and beverage manufacturing or for food and beverage manufacturing equipment repair and replacement, contact Precision Electric

PET Blow Molding

The increasing requirements being placed on food and beverage manufacturingare accompanied by growing demands on the machines in the consumer goods industry. The endcustomers in this industry are demanding machines and production lines with maximum availability, while calling for flexible product retooling and formatchanges as well as simple, consistent operator control of the machinery. Long maintenance intervals, clear error messages, the speedy worldwideavailability of spare parts and enormous energy efficiency for the machines are also important for success. Only acompany that effectively masters all the challenges it faces can be successful in the marketplace.Lenze offers the most modern automation and motion technology for the consumer goods industry based on the three standards of cost awareness, maximumquality and flexibility.PET blow molding with Lenze Motion Centric Automation is a complete solution: bottles are formed, filled, capped and labeled. Motion Centric Automation from Lenze is the easy way to secure smooth procedures in almost anybeverage line. Lenze offers Motion Centric Automation products for PET blow molding to ensure that all processes remain simple and free of any problems.Motion Centric Automation from Lenze is a complete manufacturing solution from start to finish for PET blow molding processing. Below are the steps used with Lenze Motion Centric Automation products duringPET blow molding processing.Applying even heat and air to create the perfect form is the first step in PET blow molding. The preforms are separated by the automatic preform loader and transported upwards to create the perfect form for PET blow molding process. Gravity thenallows them to slide into the in-feed wheel, from where they are loaded onto the transport chain. Infrared lamps in the heater heat up the preforms inrotation, whereby the neck of the bottles is held in shape at a lower temperature. The thermal treatment is combined with ventilation. At the heaterexit, arms of the PET blow molding carousel pick up the preforms below the neck. The form is completed and blowing process begins. The nozzle is lowered intothe preform and lateral pre blowing begins, followed by high pressure blowing, which presses the bottle wall against the mold. After cooling, an arm thenloads the bottles onto the transport chain.Filling And CappingFilling quickly, precisely and without interruptions: the empty PET bottles are conveyed to the filler carousel by the transport chain. The filler nozzleis quickly lowered into the empty bottle and starts to fill it, whereby a FlexCam cam profile ensures that any formation of foam is largely avoided.During the process, the nozzle is slowly moved up to match the fill level until the bottle is full.When closing bottles at high speed, productivity is key: the transport chain moves the filled bottles to the capper. This presses the preheated caps overthe bottle thread and the bottles are then closed via torque-controlled rotation. Once this is complete, the closed bottles are sent to the labeler.Individual selection of drive components based on power requirements and the dynamic performance required. Highly dynamic servo drives and compact asynchronous motors with large speed setting ranges for all areas of bottle conveying benefit from a systematic arrangement: the finished bottles arrive in a single row, arranged one behind the other. The Cartesian coordinate robot picksup three or four bottles and lays them sideways onto a second conveyor belt. A touch probe sensor detects when enoughbottles are lined up at the end of the in-feed belt. The Cartesian coordinate robot then picks these up, controlled via a fixed motion profile for grouping.LabelersPrecision is critical during wrap-around labeling: a rotary worm screw loads the bottles into the carousel, where they also rotate. In the labelingstation, a servo-driven transport roller continuously draws labels from the web, while the web guide guarantees straight-line label pick-up. The labelsare then cut to the precise size in a servo-controlled trimming process and two narrow strips of hotmelt adhesive are applied. The labels are thenapplied to the rotating bottles, after which the finished bottles are transported for secondary packaging.Pick-And-PlaceBenefit from a systematic arrangement: the finished bottles arrive in a single row, arranged one behind the other. The Cartesian coordinate robot picksup three or four bottles and lays them sideways onto a second conveyor belt. But how does the grouping work? A touch probe sensor detects when enoughbottles are lined up at the end of the in-feed belt. The Cartesian coordinate robot then picks these up, controlled via a fixed motion profile.Film WrappersThe next stage is packaging: here, the bottles previously arranged in groups of three or four arrive at the film wrapper lined up directly behind oneanother. The compartment conveyor chain ensures longitudinal grouping for packaging in 6-packs. The individual groups can now be wrapped in shrink film.The film is unwound and trimmed off by a servo-controlled cutter. The front edge of the film is then guided underneath the bottle group. A roller picksup the end by rolling over the pack and wrapping the film around it. The bottles are now ready for the shrink tunnel.Shrink TunnelsEverything needs to fit correctly: the bottles previously wrapped in shrink film are transported into the shrink tunnel.Under controlled and constant heat, the film shrinks to tightly fit the bottles. In the delivery area, the bundles created then cool down and are readyfor palletizing.PalletizersA parallelogram-type robot with reinforced base construction and sufficient arm length assumes responsibility for loading the pallet. The motion profilesof the robot kinematics can be calculated as axis movements and controlled using Lenze Controller-Based Automation with predefined profiles. Thesemovements are synchronized with the conveyor belt.To learn more about PET blow molding or for Lenze Motion Centric Automation repair and replacement quotes, contact Precision Electric.
