Abstract
Abstract Stacker especially for items having greater thickness on one side than on the other, such as newspapers. The device receives such materials with same so aligned that the thicker sides are all on the same side with respect to each other, forms partial stacks of such materials, restacks same with the partial stacks alternately reversed and then discharges the materials in a stacked form wherein the stacks are of uniformly vertical height and alignment. The stacker has a pair of operatively rotatable compartmented platens. Means are provided for alternately filling compartments of first one platen and then the other platen, effecting partial rotation of each platen as a compartment of same is filled, emptying said filled compartments while subsequent compartments thereof are being filled and carrying away and further stacking the materials discharged from said platen. The oppositely directed rotation and alternate discharging of said platens onto a single conveyor effects alternately opposite positioning of stacks formed in said platens whereby the greater thickness on one side of the components being stacked will be compensated and a straight rectangular final stack will be built.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
210 words
A stacking device for stacking of articles, particularly papers, which are of different thicknesses on opposite sides, comprising a catching mechanism for partial stacks and a rotating mechanism for rotating the partial stacks, said rotating mechanism having two rotary platens which are arranged at different heights and which can be oppositely rotated in a stepwise manner, said rotary platens each having at least two pockets for receiving partial stacks, the axes of rotation of which are both arranged vertically and which viewed in ground view are spaced from one another in such a manner that each one pocket of the upper rotary platen can be caused to coincide with one pocket of the lower rotary platen in a delivery position, stationary feed mechanisms for filling the pockets of the rotary platens, said feed mechanisms being arranged above the rotary platens, a deflector device for the alternate feeding of a continuous stream of articles to one of the feed mechanisms, discharge mechanisms for removing the partial stacks which are provided in the pockets, a lowering mechanism for lowering the upper partial stack onto the lower partial stack and a collecting mechanism for stacking the stack units one on top of the other, said stack units comprising the two aforementioned partial stacks.
Claim 2
Dependent Claim
210 words
A stacking device for stacking of articles, particularly papers, which are of different thicknesses on opposite sides, comprising a catching mechanism for partial stacks and a rotating mechanism for rotating the partial stacks, said rotating mechanism having two rotary platens which are arranged at different heights and which can be oppositely rotated in a stepwise manner, said rotary platens each having at least two pockets for receiving partial stacks, the axes of rotation of which are both arranged vertically and which viewed in ground view are spaced from one another in such a manner that each one pocket of the upper rotary platen can be caused to coincide with one pocket of the lower rotary platen in a delivery position, stationary feed mechanisms for filling the pockets of the rotary platens, said feed mechanisms being arranged above the rotary platens, a deflector device for the alternate feeding of a continuous stream of articles to one of the feed mechanisms, discharge mechanisms for removing the partial stacks which are provided in the pockets, a lowering mechanism for lowering the upper partial stack onto the lower partial stack and a collecting mechanism for stacking the stack units one on top of the other, said stack units comprising the two aforementioned partial stacks.
Claim 3
Dependent Claim
30 words
A stacking device according to claim 1, wherein each rotary platen has four pockets which can be moved by 90* rotations of the rotary platen successively into the delivery position.
Claim 4
Dependent Claim
14 words
A stacking mechanism according to claim 1, wherein the feed mechanisms have compartmented wheels.
Claim 5
Dependent Claim
33 words
A stacking device according to claim 1, wherein the lowering mechanism has a removable platform which is arranged approximately at the level of the bottoms of the pockets of the upper rotary platen.
Claim 6
Dependent Claim
56 words
A stacking device according to claim 4, wherein the removable platform consists of four swingable components which are formed such, and the swivel points of which are arranged such, that during the removal of the platform the corners of the partial stack rest on the bottom components until shortly before the complete removal of the platform.
Claim 7
Dependent Claim
21 words
A stacking device according to claim 4, wherein the removable platform is provided with balls which project above the supporting surface.
Claim 8
Dependent Claim
21 words
A stacking device according to claim 1, including vertical stops for guiding the partial stacks are arranged in the lowering mechanism.
Claim 9
Dependent Claim
25 words
A stacking device according to claim 1, wherein between the delivery points of the rotary platens and the lowering mechanism there are arranged conveyor belts.
Claim 10
Dependent Claim
20 words
A stacking device according to claim 8, wherein the conveyor belts can be swung upwardly for aligning the partial stacks.
Claim 11
Dependent Claim
41 words
A stacking device according to claim 1, wherein the collecting mechanism has a lifting mechanism for the stack units and a support mechanism for the entire stack which is to be formed, which support mechanism is arranged above said lifting mechanism.
Claim 12
Dependent Claim
36 words
A stacking device according to claim 10, wherein the lifting mechanism has spaced apart parallel support elements and wherein the retractable support mechanism consists of parallel rods which can be moved between the said support elements.
Claim 13
Dependent Claim
40 words
A stacking device according to claim 11, wherein the lifting mechanism is arranged below one conveyor belt which consists of several parallel narrow individual belts and wherein the support elements can be guided through the spaces between the individual belts.
