Filed:

Jul 20, 1983

Appl. No.:

6/515513

Inventors:

Walter E. Lotz - Lantana FL

International Classification:

B26D 156

US Classification:

493370

Abstract:

An interleaver for providing a sheet of paper for each piece of meat moving along a conveyor includes a trap door conveyor section for removing undersized pieces in response to measurements made by photo optical sensors. A knife crushes paper from a paper roll to sever a web of the paper into the sheets. A conveyor pulls the severed sheets from the knife, and air blower guides the web to the knife and prevents the next leading edge of the web from sticking to the knife. Two paper rolls are provided, one roll operating while the other roll stands by. Photo optical sensors monitor the feed from the rolls and switch the feed to the stand by roll if there is an interruption in the feed from the first roll. In addition, both rolls may operate together. A brake is provided for each paper roll, and each paper roll is fixed to a spindle which provides for adjustment of the position of the paper roll axially on the spindle.

Abstract:

Thin sheets on which a product is held by limited adhesion are transferred from a first conveyor onto a speedup conveyor which slides the sheets, one by one, onto a pair of intermittently rotatable paddles. The paddles comprise a lattice of low-friction material and define receiving surfaces angled toward one another along a direction in which the sheets slide. The paddles rotate 1/2 revolution in response to the leading sheet on the speedup conveyor passing a photocell and form a stack in a compartment on an intermittently moving conveyor below. When a predetermined count of sheets is in the stack, the intermittently moving conveyor is advanced to move an empty compartment under the paddles.
