[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for processing a workpiece such as a steel plate, for example, by punching.

[0002]

2. Description of the Related Art In a conventional machining apparatus of this type, a support table for supporting a workpiece is provided corresponding to a machining mechanism having a tool such as a drill. And
In a state where the work is set at a predetermined position on the support table, the work is subjected to processing such as drilling by the processing mechanism.

[0003]

However, in this conventional processing apparatus, an operator carries in an unprocessed work on a support table, sets the work, and removes the processed work from the support table and unloads the work. Therefore, there is a problem that the work of attaching / detaching and carrying in / out the work is troublesome and time-consuming.

In addition, when the work is attached to or detached from the support table, it is necessary to interrupt the processing operation of the work by the processing mechanism, so that there is a problem that the working efficiency is poor. In addition, when attaching and detaching the work, it is necessary for the operator to clean chips and the like accumulated on the processed work and the support table, and there is a problem that the cleaning work is troublesome and time-consuming.

[0005] The present invention has been made by paying attention to such problems existing in the prior art. It is an object of the present invention to provide a processing apparatus capable of efficiently loading and unloading a work to and from a processing position and improving work efficiency.

According to a fifth aspect of the present invention, in the processing apparatus according to any one of the first to fourth aspects, an unloading mechanism for unloading the processed workpiece from the unloading side temporary placing table is provided. It was done.

According to a sixth aspect of the present invention, in the processing apparatus according to any one of the first to fifth aspects, between the processing position and the unloading position, a processed workpiece supported by a support. In order to remove chips and the like from above, an air nozzle for blowing air toward the processed work is provided.

In the processing apparatus according to the first aspect, the support of the work moving mechanism is moved to a loading position corresponding to the loading temporary storage table, and in this state, the support is moved from the loading temporary storage table to the support. An unprocessed work is carried in. Thereafter, the support is moved to a processing position corresponding to the processing mechanism, and in this state, the workpiece is subjected to processing such as drilling by a tool of the processing mechanism. After the completion of the processing, the support is moved to an unloading position corresponding to the unloading temporary storage table, and in this state, the processed work is unloaded from the support onto the unloading temporary storage table.

As described above, the loading and unloading of the workpiece to and from the processing position is automatically and efficiently performed, so that the entire time required for the processing including the loading and unloading of the workpiece can be reduced, and the working efficiency can be improved. be able to.

In addition, while the support is moved to the processing position and the work is being processed, the unprocessed work can be loaded on the loading temporary storage table, and the unloading temporary storage table can be loaded. The processed work on the table can be carried out. For this reason, after the processing of the work is completed, the processed work on the support is promptly carried out to the unloading temporary storage table, and the unprocessed work on the loading temporary storage table is quickly transferred to the support. And the operation rate of the apparatus is improved.

In the processing apparatus according to the second aspect, when the work is carried into the support from the carrying-side temporary placing table,
The work is positioned at a predetermined position on the support by the positioning means. Therefore, when moving the support to the processing position,
The predetermined processing portion on the work can be accurately arranged to face the tool of the processing mechanism.

In the processing device according to the third aspect, when the work is carried into the support from the carrying-in temporary placing table,
The work is clamped from both sides by the clamp device.
Therefore, there is no possibility that the work will blindly move on the support when the support is moved and when the work is processed by the processing mechanism.

In the processing apparatus according to the fourth aspect,
While the support is moved to the processing position and the processing of the workpiece is being executed, the unprocessed workpiece is automatically loaded onto the loading temporary storage table by the loading mechanism. For this reason, it is possible to easily and efficiently carry in the unprocessed work into the carry-in side temporary placing table, and it is possible to improve the operation rate of the apparatus.

In the processing apparatus according to the fifth aspect, while the support is moved to the processing position and the processing of the work is being performed, the processed work is transferred from the unloading-side temporary placing table by the unloading mechanism. It is automatically unloaded. Therefore, it is possible to easily and efficiently carry out the processed work from the carry-out temporary storage table, and it is possible to improve the operation rate of the apparatus.

In the processing apparatus according to the sixth aspect, in the process of moving the support from the processing position to the unloading position after the processing is completed, air is blown onto the processed work supported by the support, and Chips and the like accumulated on the work are removed. The work from which chips and the like have been removed is placed on the unloading-side temporary placing table. For this reason, the operator does not need to perform the operation of removing chips and the like.
