A slip sheet dispenser is a specialized type of pick and place unit. Palletizing typically requires cardboard sheets (slip sheets) to be added throughout the process to prevent damage to the product.
Generally there is a slip sheet known as a nail guard placed on the empty pallet to prevent damage from possibly protruding nails and to keep the product from potentially getting dirty. There are also typically slip sheets called tier sheets inserted in between each layer packed on the pallet. Lastly sometimes it is desirable to have a top tier or cap sheet on the top layer as an added measure of protection for the bundle.
The slip sheet dispenser handles all of these tasks. It is designed to automatically pick up a cardboard sheet from a magazine travel up and over to where the pallet is and deposit directly on it or on the next layer as need be. This is accomplished with a vacuum head that consists of a vacuum generator and a series of suction cups arrayed in a suitable pattern designed to keep the sheet stable while moving. The vacuum head is mounted on a vertical linear guide with movement supplied by an air cylinder and that entire sub assembly is mounted on a horizontal linear guide with movement supplied by a gear motor.
The slip/tier sheet dispenser is a simple system which provides time and cost savings and adds product protection while giving a degree of accuracy not achievable with hand packing. The Jantz Advantage TS 4840 was specifically designed to integrate with an existing palletizer but can easily be modified to almost any application.
