Abstract
Abstract A device for producing a stack of bricks has means for forming, in one layer of the stack, passages for receiving the arms of a fork-lift device. The layers of the stack above this layer are prevented from collapsing into the passages by an intermediate sheet-like supporting layer. The stack is produced on a stacking table which can be lowered stepwise, and the various layers are fed to the stacking table by gripper means.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
258 words
A device for forming a stack of bricks comprising a plurality of first layers of bricks, a second layer of bricks in which passages are provided to receive the arms of fork-lifting means, and an intermediate layer arranged between the second layer and the first layers above the second layer, said device comprising first and second conveyor means, first gripper means operative to deposit layers of bricks on the first conveyor means and to deposit layers of bricks on the second conveyor means, stop means for the brick layers, said stop means being arranged at the downstream end portion of the first conveyor means, a stacking table arranged to be lowered stepwise, second gripper means operative to transfer layers of bricks from the first conveyor means and to deposit same on the stacking table whereby to form the first layers, gap-forming means arranged beyond the downstream end portion of the second conveyor means, said gap-forming means including stop means for the brick layers on the second conveyor means, said gap-forming means being movable in the direction of movement of the second conveyor means to separate the bricks in order to form said passages in the layer of bricks thereon whereby said layer of bricks forms said second layer, and third gripper means operative to remove one said intermediate layer from a stack thereof and to deposit same on the said second layer present on the gap-forming means, and to deposit the said second layer with the intermediate layer thereon on the uppermost first layer on the stacking table.
Claim 2
Independent Claim
258 words
A device for forming a stack of bricks comprising a plurality of first layers of bricks, a second layer of bricks in which passages are provided to receive the arms of fork-lifting means, and an intermediate layer arranged between the second layer and the first layers above the second layer, said device comprising first and second conveyor means, first gripper means operative to deposit layers of bricks on the first conveyor means and to deposit layers of bricks on the second conveyor means, stop means for the brick layers, said stop means being arranged at the downstream end portion of the first conveyor means, a stacking table arranged to be lowered stepwise, second gripper means operative to transfer layers of bricks from the first conveyor means and to deposit same on the stacking table whereby to form the first layers, gap-forming means arranged beyond the downstream end portion of the second conveyor means, said gap-forming means including stop means for the brick layers on the second conveyor means, said gap-forming means being movable in the direction of movement of the second conveyor means to separate the bricks in order to form said passages in the layer of bricks thereon whereby said layer of bricks forms said second layer, and third gripper means operative to remove one said intermediate layer from a stack thereof and to deposit same on the said second layer present on the gap-forming means, and to deposit the said second layer with the intermediate layer thereon on the uppermost first layer on the stacking table.
Claim 3
Dependent Claim
34 words
A device according to claim 1, wherein the gap-forming means comprises a plurality of plates each arranged to receive at least one row of bricks, said plates being relatively movable in a horizontal direction.
Claim 4
Dependent Claim
22 words
A device according to claim 1 further comprising overhead track means, said third gripper means being movable along said overhead track means.
