Abstract

PROBLEM TO BE SOLVED: To make it possible to carry out next processing during printing and thereby improve production efficiency by installing a printer in the rear stage of an accumulator which accumulates parts processed by a plate processing machine and printing on parts delivered from the accumulator in the direction of the X and Y axes. SOLUTION: The head 62 of an ink jet printer as a printing means 43 is moved in the direction of the Y axis along the Y axis frame 58 by turning the Y axis motor My and thereby circulating a belt 60 while avoiding an interference with a holding means 42 of a part support table 4. The holding means 42 is moved in the direction of the X axis through a chain 70 by turning an X-axis motor. The head 62 is supported on a fixing device 42 through a lift cylinder 63 in a liftable manner. Printing of bar codes is carried out by injecting ink 19 to a part P held by the holding means 42 from the head 62 and combining its movement in the Y axis and the movement of the part P in the direction of the Y axis by the holding means 42.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a part printing apparatus for a sheet material processing machine, and in particular, to a part printing apparatus for a sheet material processing machine, which prints on a processed part by a printing apparatus provided at a later stage of an integrating device of the sheet material processing machine. About.

[0002]

2. Description of the Related Art It is well known that printing is performed on parts processed by a plate material processing machine such as a punch press and the like, and management of each part is performed.

[0003] As described above, a method of printing on parts and managing the parts in units includes, for example, a conventional automatic warehouse, a turret punch press, and an unloading device.

[0004] The works stored in the automatic warehouse are carried one by one into a turret punch press, where they are processed and printed.

[0005] The processed and printed work is:
It is conveyed as a product part to the last unloading device, and is integrated in an integrated device constituting the unloading device.

[0006]

SUMMARY OF THE INVENTION The above prior arts include:
There are the following issues.

(1) Production efficiency decreases. Conventionally, as described above, a workpiece is processed by a turret punch press and printed.

In this case, the processing is performed in cooperation with a punch and a die, and the printing is performed, for example, by applying a percode by an ink jet printer.

However, since this printing is performed during processing, that is, interrupted during processing, the efficiency of the processing and production itself decreases.

For example, during the printing process, there is an adverse effect such that the next processing cannot be performed.

(2) Printing cannot be performed at an arbitrary position. An ink jet printer, which is a conventional printing unit, can print only one of them, for example, only the X-axis direction or only the Y-axis direction.

Therefore, there is little freedom in the printing range, and it is difficult to print at an arbitrary position on a part.

[0013] As a result, adverse effects such as insufficient management of parts are caused.

An object of the present invention is to provide a printing device at a stage subsequent to an accumulating device of a plate material processing machine, thereby enabling the next processing process during the printing process, thereby improving the production efficiency, and further, freeing the printing range. By providing a degree of accuracy, it is possible to print at an arbitrary place and to thoroughly manage parts.

[0015]

According to the present invention, as shown in FIG. 1 to FIG. 5 or FIG. 6, a printing device is installed at a stage subsequent to an accumulating device 3a for accumulating parts P processed by a plate material processing machine 2. ,
A technical measure is taken to print in the X-axis direction and the Y-axis direction on the part P carried in from the accumulation device 3a.

More specifically, according to the present invention, as shown in FIGS. 1 to 5, a part support table 4 is provided at a stage subsequent to an accumulating device 3a for accumulating parts P processed by the plate material processing machine 2, The parts support 4 supports the parts P transported from the stacking device 3a, and is rotatably attached to supporting means 41.
Gripping means 42 capable of gripping and carrying parts P supported by supporting means 41 and movable in the X-axis direction, and printing on parts P carried in by gripping means 42 and capable of moving in the Y-axis direction It is preferable that the printing apparatus includes a printing unit 43.

Further, according to the present invention, as shown in FIG. 6, an accumulating device 3 for accumulating parts P processed by the plate processing machine 2 is provided.
The part support table 4 is provided at a stage subsequent to the part a. The part support table 4 supports the parts P transported from the stacking device 3a, and is supported by the support means 41 rotatably mounted and the support means. While printing on the parts gripped and carried in by the gripping means of the stacking device,
It may be constituted by printing means movable in the axial direction.

Therefore, according to the configuration of the present invention, since the printing is performed on the processed part P, the next processing can be performed during the printing processing, thereby improving the production efficiency. Since printing is performed in the axial direction and the Y-axis direction, there is a degree of freedom in the printing range, and printing can be performed at an arbitrary position, and the management of parts is thoroughly performed.
