Abstract
A continuous downstacker apparatus is operable for continuously stacking product in a predetermined stacked pattern. The downstacker apparatus includes a pair of lowerating-pushing heads which continuously move in a vertical elliptical walking beam pattern for receiving, stacking and pushing stacked product from a stacking chamber. The product is delivered to the stacking chamber by conveyor means and the lowerating-pushing heads are shiftable on a support frame for vertical and horizontal components of movement during the stacking and pushing cycle.
Claims10
A downstacker apparatus for continuously stacking dimensionally stable product comprising;
- a support frame;
- means on said support frame defining a stacking chamber, a stack accumulation area for receiving and supporting stacked product from the stacking chamber,
- conveyor means on said frame for continuously delivering product in a downstream direction and discharging the product into the stacking chamber,
- a pair of substantially identical lowerating-pushing heads each having an upper product support element for supporting product to be stacked thereon;
- and each head having a vertical pushing element,
- means mounting said lowerating-pushing heads on said frame for continuous vertical shifting movement of said heads between an elevated position and a lower position;
- means mounting said lowerating-pushing heads on said frame for shifting movement of said heads between an upstream retracted position adjacent the stacking chamber and a downstream position in said stacking chamber,
- drive means operatively connected with said lowerating-pushing heads for continuously shifting the heads through a vertical elliptical path of travel, one of said heads during said travel moving downwardly from a fully elevated position while in the downstream position to a fully lowered position, simultaneously during upward movement of the other head from a fully lowered position while the other head is in the upstream retracted position, said one head supporting product in stacked relation on the product support element thereof until said one head reaches the fully lowered position, said other head then moving to the downstream position while in the fully elevated position to move the stacked product on said one head to the stack accumulation area.
A downstacker apparatus for continuously stacking dimensionally stable product comprising:
- a support frame;
- conveyor means on said frame for continuously delivering product in a downstream direction and discharging the product into a stacking chamber,
- a pair of substantially identical lowerating-pushing heads each having means thereon for supporting product to be stacked thereon, and each head having means thereon for engaging and pushing product from the other head,
- means mounting said lowerating-pushing heads on said frame for continuous oscillating movement of said heads through a continuous cyclic path of travel,
- drive means operatively connected with said lowerating-pushing heads for continuously shifting the heads through said continuous cyclic path of travel, one of said heads during said travel moving downwardly from a fully elevated position while in the downstream position to a fully lowered position, simultaneously during upward movement of the other head from a fully lowered position while the other head is in the upstream retracted position, said one head supporting product in stacked relation on the product supporting means thereof until said one head reaches the fully lowered position, said other head then moving to the downstream position while in the fully elevated position to push the stacked product on said one head by said pushing means from the stacking chamber to a stack accumulation area.
