Abstract

Abstract A stacking device for wire grids such as those welded grids used for reinforcing concrete, has vertical guides into which the free ends of a selected longitudinal wire of the grid slide so as to form a stack, one grid on top of another. One of the vertical guides can be pivoted out of its vertical position so as to release the stack onto a transporting device for removal.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 205 words
A stacking device for wire grids such as welded reinforcing grids, the device defining a deposition area and having means for guiding the grids received from a manufacturing machine to a location above the deposition area, said means comprising support bars adapted to support said grids on their way to and to release said grids above said deposition area, limit panels for lateral guidance of said grids, said limit panels having horizontally protruding parts adapted to keep the ends of said grids down and to restrain, in combination with said support bars, said grids from bending excessively and from sliding off said support bars prematurely, said stacking device further including means for releasing the grids above the deposition area, wherein a pair of opposed substantially vertical guides are provided, each of said guides being composed of two upright rails horizontally spaced apart only a sufficient distance so as to receive therebetween end sections of a selected longitudinal wire of each of the grids received on said support arms, the guides extending to the deposition area and serving to guide the grids during their downward movement, one of the guides being movable out of engagement with the end of the grids for releasing the stack grids.
Claim 2
Dependent Claim 205 words
A stacking device for wire grids such as welded reinforcing grids, the device defining a deposition area and having means for guiding the grids received from a manufacturing machine to a location above the deposition area, said means comprising support bars adapted to support said grids on their way to and to release said grids above said deposition area, limit panels for lateral guidance of said grids, said limit panels having horizontally protruding parts adapted to keep the ends of said grids down and to restrain, in combination with said support bars, said grids from bending excessively and from sliding off said support bars prematurely, said stacking device further including means for releasing the grids above the deposition area, wherein a pair of opposed substantially vertical guides are provided, each of said guides being composed of two upright rails horizontally spaced apart only a sufficient distance so as to receive therebetween end sections of a selected longitudinal wire of each of the grids received on said support arms, the guides extending to the deposition area and serving to guide the grids during their downward movement, one of the guides being movable out of engagement with the end of the grids for releasing the stack grids.
Claim 3
Dependent Claim 17 words
A stacking device according to claim 1, in which the vertical guides have upwardly expanded funnel-like extensions.
Claim 4
Dependent Claim 40 words
A stacking device according to claim 1 or claim 2, in which the vertical guide for the forward ends of the grids is adjustably and fixably arranged on a support rail 5 extending in the longitudinal direction of the grids.
Claim 5
Dependent Claim 65 words
A stacking device according to claim 1, in which the vertical guide for the forward ends of the grids is formed by one arm of a two-arm lever, and the device including a working cylinder having a piston rod, the piston rod being connected to the other arm of the lever to pivot the guide from its vertical operating position into a substantially horizontal position.
