Abstract
A metal sheet is supported and transported in relation to a punching and/or shearing station, by supporting the sheet on upwardly projecting flexible bristles, the tips of which define a supporting plane. The bristles have their bases embedded in strips that are removably jammed in grooves defined in a stationary base structure. A conveyor, arranged beside the supporting plane includes a driven, endless belt. The belt has transversally extending bristle bars mounted to it so that, in its carrying run, its upwardly projecting bristles have tips which are effectively coplanar with the stationary supporting surface.
Claims5
A device for supporting and transporting a metal sheet in relation to a workstation at which the metal sheet is to be processed by being subjected to at least one of punching and shearing,
- said device comprising:
- a supporting plane for the metal sheet, including:
- a plurality of tubular metal sections horizontally arranged side by side, said sections being configured and secured relative to one another so as to define between respective adjoining ones of said sections respective upwardly opening spaces extending lengthwise of the respective sections;
- and
- a plurality of bristle bars, each bristle bar comprising a row of bristle tufts having flexible bristles arranged with tips upward and bases downward, for each said row said bases being embedded in a respective supporting strip;
- each said supporting strip being removably jammingly secured in a respective said upwardly opening space so as to extend lengthwise of the respective sections, with said bristle tufts projecting upwardly so that said tips of said bristles, while undeflected, provide a generally horizontal, upwardly presented though discontinuous supporting surface.
A device for supporting and transporting a metal sheet in relation to a workstation at which the metal sheet is to be processed by being subjected to at least one of punching and shearing,
- said device comprising:
- a supporting plane for the metal sheet, including:
- a stationary base;
- and
- a plurality of bristle bars, each bristle bar comprising a row of bristle tufts having flexible bristles arranged with tips upward and bases downward, for each said row said bases being embedded in a respective supporting strip;
- each said supporting strip being secured to said stationary base, with said bristle tufts projecting upwardly so that said tips f said bristles, while undeflected, provide a generally horizontal, upwardly presented though discontinuous supporting surface;
- a conveyor horizontally juxtaposed with said supporting plane, said conveyor including:
- an endless conveyor belt entrained about two sets of pulleys so as to have a generally horizontal, upwardly presented carrying run arranged over a return run;
- a plurality of bristle bars, each bristle bar comprising a row of bristle tufts having flexible bristles arranged with the tips upward and bases downward, for each said row said bases being embedded in a respective supporting strip;
- and
- means removably securing each said conveyor belt bristle bar supporting strip to said conveyor belt so as to extend crosswise of said conveyor belt with said bristle tips of said conveyor belt bristle bars projecting away from said conveyor belt;
- said bristle tips of said conveyor belt bristle bars, while undeflected, providing while located on said carrying run of said conveyor belt a generally horizontal, upwardly presented though discontinuous supporting surface which is substantially coplanar with said supporting surface of said supporting plane;
- a workstation vertically juxtaposed above said supporting plane and arranged to process the metal sheet by subjecting the metal sheet to at least one of punching and shearing;
- and
- means for horizontally displacing the metal sheet from said supporting plane onto said carrying run of said conveyor belt, said displacing means including:
- a batten arranged to engage an edge of the metal sheet;
- and
- means for displacing said batten horizontally while in edgewise contact with the metal sheet, in a direction transverse to said carrying run of said conveyor belt.
