A pedestal 43 is provided on the plurality of conveyor columns 41 so as to extend in the left-right direction in FIG. Further, a plurality of conveyor brackets 17 are erected on the gantry 43 in the left-right direction in FIG. The above interval is
A material exchange arm 45 provided in the material supply exchange device 15 is provided to be able to pass through.

On the upper part of each of the plurality of conveyor brackets 17, the above-mentioned many support rollers 19 are mounted substantially horizontally, and further, for example, a number of reference members as abutment members having a reference surface SL against which the material M abuts. The roller 21 is mounted substantially vertically.

The material supply exchange device 15 has wheels 51 on two rails 49 extending left and right in FIG. 6 on the floor.
It is provided so as to be able to travel and move through. As shown in FIGS. 4 and 5, each of the two switching device main bodies 47 has a vertical frame 53 and a horizontal frame 55 so as to form an upward U-shape.
, And the two switching device main bodies 47 are integrally connected by a connection frame 57.

One end of a driving cylinder 59 is provided on the floor near each horizontal frame 55, and the tip of a piston rod 61 of the driving cylinder 59 is connected to the horizontal frame 55. The exchanging device 15 is moved in the left-right direction in FIG.

Each of the vertical frames 53 is provided with two material replacement beams 63 extending upward and downward along the guide rails (not shown) inside the upward U-shape in FIG. 5 and extending in the left-right direction in FIG. I have.

Further, as shown in FIG. 5, an elevating cylinder 67 is provided on the outer side of each vertical frame 53 in the left-right direction in FIG. A sprocket 69 is supported at the tip, and a chain 71 is wound around the sprocket 69. One end of the chain 71 is fixed to the vertical frame 53, and the other end of the chain 71 is attached to the material exchange beam 63. Note that each material replacement beam 63 is driven up and down while maintaining a substantially horizontal position by the two lifting cylinders 67 moving up and down in synchronization.

As shown in FIG. 5, each of the material replacement beams 63 has a large number of material replacement arms 45 extending inward in the upward U-shape in the left-right direction (vertical direction in FIG. 6). Provided, each material replacement arm 4
5 is a plurality of conveyor brackets 1 on the gantry 43 described above.
7 so as to be able to pass through.

Note that a plurality of material replacement beam columns 73 are erected on the floor at intervals in the left-right direction in FIG. As shown in FIG. 4, the material replacement beam support column 73 is for placing each material replacement beam 63 in the original position.

With the above configuration, the material supply exchange device 1
5 is such that, by the operation of the drive cylinder 59, the exchanging device main body 47 is moved between the solid line and the two-dot chain line in the left-right direction in FIG. 5, and the right material in FIG. It is raised and lowered between the two-dot chain line. Therefore, the material replacement arm 45 is moved vertically with respect to the roller line RL of the support roller 19, and is moved left and right with respect to the reference plane SL of the reference roller 21.

Referring to FIG. 8, a control device 75 includes an input device 79 for inputting data such as a processing program when the material M is cut by the cutting machine 11 and a display device 81 to a CPU 77 as a central processing unit. And a memory 83 for storing data input by the input device 79 are connected.

Further, the CPU 77 instructs the CPU 77 to slightly lift the material M placed on the support roller 19 by the material replacement arm 45 based on the processing program in the memory 83, and then place the material M on the reference surface SL of the reference roller 21. A command unit 85 is connected to the material supply / replacement device 15 for issuing a command to move the material replacement arm 45 in the width direction of the support roller 19 by a predetermined set movement distance in order to abut.

With the above configuration, for example, the material M on the support roller 19 is sent to the cutting machine 11 by the feeding roller conveyor 13 based on a processing program, and cut into a predetermined size. When the cutting is completed, the remaining material M is returned on the support roller 19 as shown in FIG. When the position of the material M at this time is A dimension from the reference surface SL of the reference roller 21 in the lower part in FIG. 6 and B dimension from the reference surface SL of the reference roller 21 in the upper part in FIG. If the material M is a rectangular material, it rolls on the support roller 19 and comes into contact with the reference surface SL of the reference roller 21, but if the material M is a rectangular material, it does not come into contact with the reference surface SL of the reference roller 21 at the same position.

However, when a command is given from the command section 85 of the control device 75 to the material supply exchange device 15, for example, the lifting cylinder 67 on the right side in FIG.
As shown in (A), the material M is slightly lifted by the material replacement arm 45 with respect to the roller line RL of the support roller 19.

Thereafter, the operation of the drive cylinder 59 causes the replacement device main body 47 to move rightward in FIG. 5 by a predetermined set moving distance. This set moving distance is set to a value larger than the above-described B dimension.

Accordingly, since the material changing arm 45 moves rightward in FIG. 5, the material M first contacts the reference surface SL of the reference roller 21 at its lower end in FIG. 6 as shown in FIG. Then, the upper end side in FIG. 6 contacts the reference surface SL of the reference roller 21 as shown in FIG. The material changing arm 45 continues to move by the set moving distance. At this time, the material replacement arm 4
While the member 5 is moving, the portion of the material M that is abutted against the reference roller 21 slides on the upper surface of the material replacement arm 45.

As described above, since the entire material M is surely abutted against the reference surface SL of the reference roller 21, it is positioned on the reference line and is surely parallel to the center line.

When the remaining material is returned to the storage shelf 9,
The operation of the elevating cylinder 67 raises the material replacement beam 63, that is, raises the material replacement arm 45 as shown by the two-dot chain line in FIG. 5, so that the material M is lifted. The lifter beam 35 of the material conveying device 23 described above
In addition, the lifter arm 39 is lowered from above in FIG. 4, and the lifter arm 39 is moved up to a position below the material replacement arm 45, and then the lifter arm 39 is raised. . Thereafter, the material M is stored in the storage shelf 9 by the lifter arm 39.

In order to place the material M on the storage shelf 9 on the material feeding roller conveyor 13, the reverse operation is performed. That is, the material M in the storage shelf 9 is carried out by the lifter arm 39 of the material transporting device 23, and the material M is placed on the material exchanging arm 45 already raised as shown by the two-dot chain line in FIG. Is placed. The material replacement arm 45 is lowered until the material M is located slightly above the roller line RL of the support roller 19 before the support roller 1
The material M moves in the width direction of 9 and comes into contact with the reference surface SL of the reference roller 21. The material M is placed on the support roller 19 by the lowering of the material replacement arm 45, and the cutting machine 1
Material is sent in the direction of 1.

The present invention is not limited to the above-described embodiment, but can be embodied in other forms by making appropriate changes.

For example, a plurality of conveyor brackets 17
A material detection sensor 87 such as an optical sensor or a proximity sensor is appropriately provided between the reference rollers 21 as a material detection device for detecting that the material M has contacted the reference surface SL. Is electrically connected to the control device 75. Then, the control device 75 gives a command to the material supply replacement device 15 so that the material M is lifted by the material replacement arm 45 based on the processing program and then moved in the width direction until the material M is detected by the material detection sensor 87. Such a configuration may be adopted.

[0049]

As will be understood from the above description of the embodiments of the present invention, according to the first aspect of the present invention, the material is placed on the material feeding device obliquely to the transport direction. However, since the material is moved up and down in the width direction of the material feeding device after the material is lifted by the material supply exchange device, the material can be surely abutted against the reference surface and positioned in parallel with the passing core.

According to the second aspect of the present invention, even if the material is placed obliquely to the conveying direction on the material feeding device, the material is lifted by the material supply exchange device and then moved in the width direction of the material feeding device. As it moves by the set moving distance set in advance,
The material can be reliably positioned against the reference plane and positioned parallel to the centerline.
