A conveyor comprising an endless accumulation chain and at least two sets of devices for effecting incremental movements of the chain at respective stations. Each set of devices includes a first device for engaging and disengaging respectively the chain, a second device engaged to the first device for moving it from a first position to a second position while it is engaged to the chain for effecting an incremental movement of a portion of the chain and for retracting the first device to the first position while the first device is disengaged from the chain, and a third device for engaging the chain to lock the chain portion in a fixed position while the first device is disengaged from the chain and for disengaging from the chain when the first device is engaged to the chain portion so that the first device may be moved to the second position for incrementally moving the chain portion. In order to incrementally move the conveyor chain, the first device is engaged to the chain, the second device is disengaged from the chain, the engaged first device is moved from the first position to the second position to effect incremental movement of the chain, the second device is engaged to the chain to maintain a chain portion position, the first device is disengaged from the chain, and the first device is retracted to the first position to repeat the method for another incremental chain movement.
A conveyor comprising an elongate endless chain and at least one set of devices for effecting incremental movements of said chain in a direction longitudinally along said chain, said set of devices comprising a first device including a cylinder having an extendable and retractable rod adapted for engaging and disengaging said chain wherein said cylinder is positioned to effect engaging and disengaging said chain by said rod, and a second device positioned and attached to said first device in a manner to effect movement of said first device from a first position to a second position while said first device rod is engaged to said chain thereby to effect an incremental movement of at least a portion of said chain in a direction longitudinally along said chain and in a manner to effect retraction of said first device to the first position while said first device rod is disengaged from said chain thereby to position said first device in a position to effect another incremental movement of at least a portion of said chain in a direction longitudinally along said chain.
A conveyor comprising an elongate endless chain and at least one set of devices for effecting incremental movements of at least a portion of said chain in a direction longitudinally along said chain, said set of devices including a first device positioned and adapted for engaging and disengaging respectively said chain, a second device positioned and attached to said first device in a manner to effect movement of said first device from a first position to a second position while said first device is engaged to said chain for effecting an incremental movement of the portion of said chain in a direction longitudinally along said chain and in a manner to effect retraction of said first device to the first position while said first device is disengaged from said chain, and a third device positioned and adapted for engaging said chain to lock the portion of said chain in a fixed position while said first device is disengaged from said chain and for disengaging from said chain when said first device is engaged to said chain so that said first device may be moved to the second position for incrementally moving the portion of said chain in a direction longitudinally along said chain.
A method for incrementally moving elongate conveyor chain in a direction longitudinally along the chain comprising the steps of:
