Description

  The present invention relates to an operation management apparatus and method for a workpiece end material generated when a predetermined type of part mold is placed in a workpiece by nesting or the like, and more particularly to an automatic and efficient end of the workpiece. The present invention relates to an operation management device for a workpiece end material capable of reusing a material and a method thereof.

  In general, in a processing system having a processing machine such as a laser processing machine or a punch press, a processing method is known in which a blank of a predetermined type of part is placed in a workpiece in accordance with a nesting program.

  In such a blanking process, an end material is generated depending on the number and type of parts to be produced. However, the end material is reused to perform blank processing to produce an additional part.

  In blank processing according to the nesting program, interrupts and changing of the processing order are frequently performed in practice, so the size and shape of the end material is the size of the end material assumed in the original nesting program. The situation was different from the sheath shape.

  And, as a method of reusing such end material, conventionally, a method of cutting an unused area of the workpiece and using it as an end material, or a large amount without using the unused area of the workpiece as an end material.

  Next, in step 108, it is determined whether or not there is a next continuous laser processing. If there is a continuous next laser processing, in step 109, it is determined whether or not there is an end material that can be used for the next processing. Determined. In addition, this determination process changes with the conditions of a scrap material so that it may mention later.

  That is, the CPU 65 of the control device 6 performs nesting of the next processing from the dimension information of the end material W1, and if the end material W1 is small with respect to the next processed part, it cannot be used for the next processing. Judge.

  When it is determined that the end material W1 can be used for the next processing, the process proceeds to step 117.

It is conveyed through.

  Moreover, as shown in FIG.6 (e), when the end materials W1 and W2 are mounted on the material pallet P2 of the material shelf apparatus 1, it is determined that the end materials W1 are the end materials to be used. Based on the control of the CPU 65 of the control device 6, the end material W <b> 1 is selectively taken out from the material pallet P <b> 2 of the material shelf device 1 and is transported to the laser processing machine 3 via the work transport means. Here, as a means for selectively removing the end material W1 from the material pallet P2 of the material shelf device 1, the floating support member 19 selectively sucks and carries the end material W1.

  Moreover, as shown in FIG.6 (f), in the state in which the end materials W1, W2, and W3 are mounted on the material pallet P2 of the material shelf apparatus 1, it is determined that the end materials W1 are used. In this case, the end material W1 is selectively taken out from the material pallet P2 of the material shelf device 1 based on the control of the CPU 65 of the control device 6, and is conveyed to the laser processing machine 3 via the work conveying means.

  In particular, as shown in FIG. 6 (g), the end materials W1, W2, W3 are mounted on the material pallet P2 of the material shelf device 1, and the end materials W4 are mounted on the end materials W1, W2, W3. When it is determined that the end material W1 is the end material to be used in the state where the end material W1 is mounted, first, the end material W4 is based on the control of the CPU 65 of the control device 6 as shown in FIG. The material pallet P2 is moved to another material pallet (third mounting place) P3, and the material pallet P2 is in a state as shown in FIG.
