Abstract
An apparatus for retention and release of pallets used in a production line system comprising pallets, means for advancing pallets, latching means, rolling means, and a rail member, wherein the latching means are pivotally coupled to the advancing means to allow pivoting of the latching means about a horizontal axis, the rolling means are affixed to the latching means, and the rail member is adapted to exert an upward force on the rolling means during advancement of the pallet for causing pivotal rotation of the latching means for sequential release of each pallet when removal of the pallet is desired.
Claims5
A pallet retention and release system for use in a production line for transportation of workpieces and for rapid installation and removal comprising:
- (a) pallets for supporting said workpieces;
- (b) means for advancing said pallets comprising a conveyor;
- (c) an apparatus for securing said pallets to said advancing means, including latching means and rolling means, wherein said latching means are connected to and pivotable upon said advancing means to allow pivoting of said latching means about an axis of the latching means, the axis having a first orientation for releasably engaging a pallet, said latching means including a locking wedge adapted for slidable engagement with a hardened button on an upper horizontal surface of said pallet to secure said pallet tightly to a platen mounted on the conveyor, and wherein said rolling means are affixed to said latching means;
- and
- (d) a rail member adapted to be engaged by the rolling means to exert a force in a direction perpendicular to said first orientation on said rolling means during advancement of said pallet for causing pivotal rotation of said latching means for disengaging said pallet when removal of said pallet is desired.
A pallet retention and release system for use in a production line for transportation of workpieces and for rapid installation and removal comprising:
- (a) pallets for supporting said workpieces;
- (b) means for advancing said pallets comprising a conveyor;
- (c) an apparatus for securing said pallets to said advancing means, including latching means, spring means, and rolling means, wherein said latching means are connected to and pivotable upon said advancing means to allow pivoting of said latching means about an axis of the latching means, the axis having a first orientation for releasably engaging a pallet, and said latching means include a locking wedge adapted for slidable engagement with a hardened button on an upper horizontal surface of said pallet, wherein said spring means urge said latching means into slidable engagement with the button on said pallet, wherein said rolling means are affixed to said latching means;
- and
- (d) a rail member adapted to be engaged by the rolling means to exert a force in a direction perpendicular to said first orientation on said rolling means during advancement of said pallet for causing pivotal rotation of said latching means for disengaging said pallet when pallet removal is desired, such engagement causing said pallet to be unsecured relative to said advancing means.
