Improvement and application of shrink label system

multi color company () is a comprehensive service provider providing decoration and packaging solutions. Quick Pak company () is the packaging service branch of multi color company and a major supplier providing promotional packaging and assembly services. The service items include: design and supply of raw materials, demonstration and custom assembly, provision of shrink packaging and shrink binding, production of cartons, bar codes, spray codes and labels, repair and repair, warehouse management and sales

in the summer of 2004, at the request of a customer who produces hair care products, quick Pak installed a shrink labeling system produced by nafm engineering services () to label a new vial. The labels used by quick Pak to decorate small cans are printed and produced in Scottsburg factory of multi color, and the printing cylinder used is etched by laser graphics. Laser graphics, located in Erlanger, KY, is the graphics service branch of multi color. This project has proved that multi color has a unique ability in serving customers. From scheme design to finishing the decoration of packing cases, it is impossible to clean the jaw frequently

the label system has a small bottle sorting unit (left), which makes the small bottles enter the groove of the conveyor belt vertically, and the conveyor belt sends them to the shrink sleeve label machine

nafm system includes an automatic small bottle stacking platform, a label machine, a steam pre shrinking channel and a stacking platform

vials move up to the conveyor belt at the end of the experiment through the automatic stacking table with rotating tray, and then enter the discharge point. Small bottles are easier to "lock" the vision of consumers. When leaving the automatic stacking table, the neck must face up. A small guide rail on the wall of the automatic stacking platform allows the vials in the correct direction to pass through, while returning the inverted vials to the tray for the next cycle. Air injection equipment is also available to assist in this process

the vial descends along the curve guide groove, which reverses the vial, so that the neck will face down when the vial is placed on the supply conveyor belt. During the period from the supply conveyor belt to the labeling machine, the vials are measured by a star wheel, and they are placed in the groove of the label conveyor belt and sent to the labeling machine. The groove can ensure that those non-standard cans will not tilt during the labeling process

the roll with shrink sleeve is placed on the rotating shaft behind the label machine, and the label tube is pulled through the floating roller to maintain the tension. The material advances to the top of the labeling machine and then descends into the machine along the vertical tail, during which the vertical tail partially opens the material and moves the material towards the plastic floating mandrel. The drum rotating against the side of the spindle contacts the film and pulls it down

an electronic eye reads the distance between the labels on the drum and triggers 6 horizontal rotary knives to cut off the bottom label from the label tube when the label is suspended. The other electronic eye checks whether there is a small can on the lower conveyor belt, and triggers the drive roller at the bottom of the spindle to "shoot" the label onto the small can when the small can passes. An electronic eye is also installed at the bottom of the spindle to check for blockage. If the electronic eye sees a label for a longer time than the set time, the labeling machine will recognize that there is a blockage, and then stop the bottle feeding star wheel

after leaving the label machine, the small can enters a 9-foot-long steam channel, where the label is retracted and fixed in place. Before entering the passage, the small tank shall pass under the horizontal angle plate. Here, the corner plate gently pushes the labels that are not firmly bonded onto the small can

this unique steam channel is equipped with more than 100 tiny plastic steam nozzles. Each nozzle has a double space, which is the smallest type of connecting valve in common use. It must be opened to suck in steam. In this way, the steam can be accurately positioned as required to obtain the best label shrinkage

the parallel transverse belt grabs the small cans when they leave the contraction chamber, places them on the conveyor belt, and transfers them to the stacking table of Garvey company (), and then manually loads the small cans into the shipping box

Ben Wilcox, the operation engineer, said: "nafm system works well and brings benefits to multi color and our customers. This project truly demonstrates our ability to provide customers with complete packaging solutions from label design." (end)
