Abstract
An apparatus for stacking skins uses an endless conveyor belt mounted on a support and driven by a drum at an upstream end, and passing around a pair of rollers. The latter are displaceable relative to the drum to define a pair of retractable and extendable conveyor arms at the downstream end by a pair of chains for cyclically displacing the rollers to extend an upper one of the arms while retracting a lower one of the arms simultaneously. A bar is affixed to the conveyor belt and is engageable with notches on the support upon the displacement of said conveyor belt for retaining a portion of the conveyor belt between the rollers.
Claims21
An apparatus for depositing or stacking objects of small thickness, comprising:
- a support having an upstream end adapted to receive said objects in succession and a downstream end;
- means at said downstream end for receiving objects to be deposited and disposed below said support;
- an endless conveyor belt mounted on said support;
- a drum on said support at said upstream end, said conveyor belt passing around said drum and forming a pair of stretches extending from said drum;
- a pair of rollers engageable with said conveyor belt and displaceable relative to said drum to define a pair of retractable and extendable conveyor arms at said downstream end of said support;
- a pair of displacing elements disposed laterally of said belt and movably mounted on said support for cyclically displacing said rollers to extend an upper one of said arms while retracting a lower one of said arms simultaneously;
- and
- a bar affixed to said conveyor belt and engageable with said support upon the displacement of said conveyor belt around said drum and said rollers to immobilize said bar for retaining a portion of said conveyor belt between said rollers while said rollers are displaced by said elements.
