Abstract

A workpiece information recognition system includes a workpiece placing tool (20) capable of placing a workpiece, a reference block (31) detachably provided on workpiece placing tool (20), an information detector configured to detect information about reference block (31), and a control device configured to receive the information of reference block (31) from the information detector. The control device includes a storage configured to store data on a relationship between the information about reference block (31) and information about the workpiece and a controller configured to recognize the information about the workpiece placed on workpiece placing tool (20) by checking the information about reference block (31) detected by the information detector with the data stored in the storage. With this configuration, the workpiece information recognition system capable of easily cope with a change in a type of the workpiece is provided.

First claim

The invention claimed is:

1. A workpiece information recognition system comprising:
a workpiece placing tool capable of placing a workpiece;
a reference object detachably provided on the workpiece placing tool;
an information detector configured to detect information about the reference object; and
a control device configured to receive the information about the reference object from the information detector,
wherein the control device includes:
a storage configured to store data on a relationship between the information about the reference object and information about the workpiece; and
a controller configured to recognize the information about the workpiece placed on the workpiece placing tool by checking the information about the reference object detected by the information detector with the data stored in the storage,
the reference object is a solid,
the information about the reference object includes information about a shape of the solid, and
the solid has a different shape depending on the information about the workpiece placed on the workpiece placing tool.

2. The workpiece information recognition system according to claim 1 , wherein the information about the reference object further includes information about a size, or a position of the solid.

3. The workpiece information recognition system according to claim 1 , wherein the information about the workpiece includes a size, a processing state, a processing method, or disposition of the workpiece.

4. The workpiece information recognition system according to claim 1 , wherein the workpiece placing tool includes a plate member in which a plurality of openings into which the workpieces are inserted is provided, and
the reference object comprises at least three reference objects, the at least three reference objects disposed apart from one another being provided in the plate member.

5. The workpiece information recognition system according to claim 1 , further comprising a workpiece conveyance unit configured to convey the workpiece placed on the workpiece placing tool,
wherein the information detector is fixed to the workpiece conveyance unit.
