Abstract

A first plate-like member on a bottom surface side is disposed in a horizontal direction. A second plate-like member is disposed in a vertical direction. A first position restricting mechanism is engaged with a first end portion including a first side that opposes the first plate-like member in a workpiece in a state where the workpiece stands while a front surface and a rear surface of the plate-like workpiece are along a vertical direction, and restricts the position of the first end portion in a plate thickness direction. A second position restricting mechanism is engaged with a second end portion including a second side that opposes the second plate-like member in the workpiece, and restricts the position of the second end portion in the plate thickness direction.

First claim

What is claimed is:

1. A workpiece storage device for storing one or more plate-like workpieces made of sheet metal, comprising:
a first plate-like member on a bottom surface side disposed in a horizontal direction, the first plate-like member being made of metal;
a second plate-like member disposed in a vertical direction that is perpendicular to the horizontal direction;
a first position restricting mechanism which is provided integrally with the first plate-like member or separately from the first plate-like member on the first plate-like member, the first position restricting mechanism being made of metal, wherein the first position restricting mechanism is configured to engage a first end portion of the workpiece that comprises a first side edge of the workpiece in a state in which the workpiece is oriented in the vertical direction and both a front surface and a rear surface of the workpiece are along oriented in a plane that extends in the vertical direction such that the first side edge of the workpiece opposes the first plate-like member, thereby restricting a position of the first end portion in a plate thickness direction of the workpiece; and
a second position restricting mechanism which is provided integrally with the second plate-like member or separately from the second plate-like member on the second plate-like member, wherein the second position restricting mechanism is configured to engage a second end portion of the workpiece that comprises a second side edge of the workpiece in the state in which the workpiece is oriented in the vertical direction such that the second side edge of the workpiece opposes the second plate-like member, thereby restricting a position of the second end portion in the plate thickness direction of the workpiece, the plate thickness direction of the workpiece being oriented perpendicular to the plane,
wherein
the first position restricting mechanism comprises a plurality of comb teeth members each comprising a first slit into which the first end portion is inserted, and
the plurality of comb teeth members are disposed in a first direction along the first side edge of the workpiece with a space provided between adjacent comb teeth members.

2. The workpiece storage device according to claim 1 , wherein the plurality of comb teeth members comprise a plurality of first slits arranged in a second direction orthogonal to the first direction such that the workpiece storage device stores a plurality of workpieces.

3. A workpiece storage device for storing one or more plate-like workpieces made of sheet metal, comprising:
a first plate-like member on a bottom surface side disposed in a horizontal direction, the first plate-like member being made of metal;
a second plate-like member disposed in a vertical direction that is perpendicular to the horizontal direction;
a first position restricting mechanism which is provided integrally with the first plate-like member or separately from the first plate-like member on the first plate-like member, the first position restricting mechanism being made of metal, wherein the first position restricting mechanism is configured to engage a first end portion of the workpiece that comprises a first side edge of the workpiece in a state in which the workpiece is oriented in the vertical direction and both a front surface and a rear surface of the workpiece are oriented in a plane that extends in the vertical direction such that the first side edge of the workpiece opposes the first plate-like member, thereby restricting a position of the first end portion in a plate thickness direction of the workpiece, the plate thickness direction of the workpiece being oriented perpendicular to the plane; and
a second position restricting mechanism which is provided integrally with the second plate-like member or separately from the second plate-like member on the second plate-like member, wherein the second position restricting mechanism is configured to engage a second end portion of the workpiece that comprises a second side edge of the workpiece in the state in which the workpiece is oriented in the vertical direction such that the second side edge of the workpiece opposes the second plate-like member, thereby restricting a position of the second end portion in the plate thickness direction of the workpiece,
wherein
the second position restricting mechanism includes a second slit into which the second end portion is inserted.

4. The workpiece storage device according to claim 3 , wherein the second plate-like member is formed with a plurality of second slits arranged in a direction orthogonal to the second side edge of the workpiece.

5. The workpiece storage device according to claim 1 , wherein the workpiece storage device stores one or more workpieces that are held and transported by a bending robot one by one to a press brake, for bending each workpiece by the press brake.

6. The workpiece storage device according to claim 3 , wherein the workpiece storage device stores one or more workpieces that are held and transported by a bending robot one by one to a press brake, for bending each workpiece by the press brake.
