The in line stacking pile chain PPC is an in line feeder suitable to create stacks of two products starting from flow of single products, collating and grouping them according to the package configuration required. This feeder is highly recommended for high-speed applications and delicate products overlapping and grouping tasks. The PPC device can be fitted onto any PPS feeder.
The first PPC element is a stacking chain made with pegs, of two different heights, applied so that they alternate with each other; the products, previously phased by the PPS system, are taken over by the PPC chain and placed on two parallel levels thanks to the particular shape of the pegs.
The lowest peg disappears under the sheet metal plan of the machine leaving the product taken from the PPS line; the highest peg, during its own path, carries forward the product that runs on the low level of the chain and meets the product left by the low peg on the high sliding plane. At the end of the sliding planes, the product of the high level will be deposited on that of the low level forming the stack.
PRODUCTS GROUPING DEVICE
The second element is an upper chain with vertical pins that receives the product’s stacks and composes multiples delivering them, at the right pitch, to the flow wrapper chain. The cantilevered construction allows this module to be lifted pneumatically for maintenance purposes or when running single stack packaging configuration.
