[Detailed description of the invention]

[0001]

This invention is based on the idea that, for example, a long sheet material to be continuously conveyed is appropriately cut, and when a variety of member pieces are cut out, marking of predetermined contents is performed on those member pieces in advance. The present invention relates to a cutting machine with a marking device that can continuously and rapidly process marking display and cutting when displaying.

[0002]

2. Description of the Related Art Various products, for example, plate cutting pieces of duct members, are cut and punched from a long plate material having a predetermined width.
In forming and the like, the raw material wound in a roll shape is sequentially pulled out, transported to various predetermined processing machines on a transport line, and cut into a predetermined shape by a cutting machine. At the time of this cutting, for example, the necessary parts for indicating the use location, the combination part, the part number, and the like are written in advance on each of the stripping parts.
In order to indicate these necessary items, the cutting machine is provided with, for example, a marking device having a marking pen that is controlled to travel in the X-axis and Y-axis directions, respectively.
Before a cutting operation by a plasma cutter whose traveling is controlled in each of the axial directions, a marking operation is performed on a predetermined portion by a marking device.

[0003]

However, in this type of conventional cutting machine with a marking device, after a marking operation is performed on the entire area of one lot portion of the plate material transported and prepared by the marking device, the cutting operation is performed. Since the cutting is performed by the plasma cutter, the cutting operation cannot be performed unless the marking operation is completed. That is, this is because the marking pen travels through the entire area in each lot unit to the front and rear edges and the left and right edges in the marking operation by the marking device. It was because it caused confusion. Further, since the cutting operation is completed in a shorter time than the marking operation, these simultaneous processes not only complicate their control but also are extremely difficult.

Therefore, the operation of the plasma cutter itself waits until the end of the operation of the marking device. As a result, the entire operation time including the marking operation and the cutting operation is the sum of the two, and the time is shortened. Could hardly be expected to improve work efficiency.

In view of the above, the present invention has been devised in view of the above-mentioned various circumstances. When a long material to be conveyed is marked for each predetermined lot unit and then cut, the lot material is cut. The cutting work is performed immediately after marking for each area in which the unit is divided into an appropriate number of sections, and during the cutting work in the previous area, the marking work is performed in the next area. It is an object of the present invention to provide a cutting machine with a marking device that can shorten the cutting time.

[0006]

In order to achieve the above-mentioned object, in the present invention, after marking is performed on a member W to be conveyed and set, cutting is performed, and the member W is conveyed. A cutting machine base 1 on which the transported member W is set, and a marker 3 for performing a predetermined marking operation for each area where the transported member W is appropriately divided and sectioned.
Similarly, the cutting operation is performed by the cutter 2 that performs the cutting operation for each area, and the cutter 2 that moves and retreats the marker 3 out of the area where the marking operation has been completed and then moves into the area. Control means 4 for causing the marker 3 moved to another area outside to perform a marking operation in that area is provided.

When the marker 3 is present in the destination area after the cutting operation is completed in the area before the movement by the control means 4, the cutter 2 is made to stand by in the area before the movement. be able to.

[0008]

In the cutting machine with the marking device according to the present invention, when the member to be conveyed W is conveyed onto the cutting machine base 1, the marker is first controlled according to the control of the control means 4 for each of the appropriately divided sections. After the marking operation is performed by 3, the cutting operation by the cutter 2 is performed.

At this time, the marker 3 after the end of the marking operation is moved out of the end area and retreated, and the marking operation is continued in that area, while the cutter 2 is moved into the area after the end of the marking operation. They are allowed to enter and perform cutting operations, and are processed in different areas in parallel.

When the cutter 2 after the completion of the cutting operation moves into the next area, and the marker 3 is present in the destination area, the cutter 2 is kept on standby.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the drawings, reference numeral 1 denotes a member W to be conveyed supplied from a predetermined member supply portion, for example, a long plate material. This is a cutting machine base for positioning and setting the W so as to cut the W. By being programmed in advance on the cutting machine base 1, for example, the X-axis along the transport direction and the direction substantially orthogonal to the transport direction are cut so as to model and cut, for example, each of the plate-taken portions constituting the air conditioning duct. A plasma type cutter 2 whose traveling is controlled via a linear mechanism in each direction of the Y axis is provided.

Before being cut by the cutter 2, a marker 3 indicating a member number or the like on each of the plate cutting pieces is programmed in advance in the X-axis and Y-axis directions via a linear mechanism. It is mounted on the cutting machine base 1 so as to be controlled for traveling.

The cutter 2 and the marker 3
Each of the markers 3 is provided by the control means 4 in each area where the surface of the member to be conveyed W is appropriately divided and divided.
First, the marker 3 moves and enters after the marking operation by the cutter 2 is completed, and the cutter 2 moves and enters after leaving. Then, during the cutting operation in the previous area where the marking operation has been completed, the marker 3 which has left the previous area and moved into the next area is controlled so as to continue to perform the marking operation. By performing the processing, parallel processing of continuous sequential marking and cutting for each area is performed.

That is, as shown in FIG. 1, the lot unit of the member W to be conveyed on the cutting machine base 1 is appropriately divided and divided into sections, for example, sections A, B, C,. As shown in (1), in the area A, first, a marking operation with the marker 3 is performed, and the cutter 2 is kept on standby during the marking operation. After the end of the marking operation in the area A, the marker 3 is moved into the area B, and the cutting operation in the area A is performed by the cutter 2 that has entered the area A. During the cutting operation in the area A, a marking operation is performed by the marker 3 transferred to the next area B in the area B. When the cutting operation is completed in the area A during the marking operation in the area B and the marking operation is continued in the area B, the cutter 2 is instructed to wait until the marker 3 moves out of the area B. I do. Hereinafter, the control means 4 instructs the control so as to sequentially move and repeat this operation to the C area, the D area, the E area, and the like.

At this time, when the cutter 2 has completed the cutting operation in the preceding area and moves into the next area, the checking operation for checking the presence or absence of the marker 3 in the next area is performed by appropriate checking means. It has become. When the marker 3 performing the marking work is present, the cutter 2 is made to wait in the front area or the like. When the marker 3 is not present, or when the marking work is completed and the marker 3 moves and retreats, The cutter 2 is immediately moved and entered, and the point is that the marker 3 and the cutter 2 do not collide with each other or are not complicated.

The division of the lot of the transported member W is not limited to the case where the transported member W is partitioned into strips at appropriate intervals along the transport direction of the transported member W as shown in the drawing. It is also possible to partition at appropriate intervals along the transport direction and to re-partition at intervals substantially orthogonal to the transport direction. In any case, even if the cutter 2 moves while the marker 3 is moving, both cutters 2 and 2 can move in the same area.
It is sufficient that care is taken so that 3 does not operate simultaneously.

The marking operation and the cutting operation may be sequentially performed from either the front side or the rear side along the conveying direction of the member W to be conveyed.
They are programmed in the control means 4 in advance.

Accordingly, when the transported member W is transported onto the cutting machine base 1, a marking operation is first performed by the marker 3 according to the control of the control means 4 for each of the appropriately divided sections, and the marking operation is performed. After the end, the marker 3 moves out of the area and retreats, a cutting operation by the cutter 2 moving into the area is performed. At this time, the marker 3 moved into another area outside the area
Performs a marking operation in the area, and when the marking operation is completed, the cutting operation is performed by the cutter 2 which has moved and entered the area. Further, when the cutter 2 moves into another area, when the marker 3 is performing the marking operation in the destination area, the cutter 2 waits in the area before the movement, etc., and the marking operation is completed and the marker 3 is moved. When the cutter 2 moves and retreats, the cutter 2 moves and enters to perform a cutting operation.

[0019]

The present invention is constructed as described above. Therefore, when marking the transported member W for each predetermined lot unit and cutting it, the inside of the lot unit is divided into an appropriate number. Since cutting is performed after marking for each sectioned area, sequential parallel processing for performing marking work in one area and cutting work in the other area can be performed.

That is, in the present invention, the marker 3 for performing the marking operation and the cutter 2 for performing the cutting operation in each of the appropriately divided sections are moved to another area by the control means 4 after the end of the marking operation. Marking and cutting are performed in parallel so that the retired marker 3 is controlled to perform a marking operation in that area, and the cutter 2 moved and advanced into the area after the marking is completed to perform a cutting operation. This makes it possible to significantly reduce the overall working time compared to a conventional cutting machine that performs a cutting operation again after the entire marking operation is completed. is there.

In the control means 4, when the cutter 2 is moved to the next area after the cutting operation is completed, and the marker 3 is present in the destination area, the cutter 2 is made to wait. Even if the marking operation takes longer time than the operation, the cutter 2 and the marker 3 are not complicated in the same area, and the continuous sequential processing can be smoothly performed.
