Abstract

PROBLEM TO BE SOLVED: To provide a method for carrying out remainings after flat bar preparation which allows a remainings carrying-out yard to be small. SOLUTION: Materials are supplied from a material supply yard 3 and remain after flat bars are cut out therefrom are accumulated. Namely if the remainings are short they are accumulated in a short piece yard P5 a remainings carrying- out yard 5, and the rest is accumulated in a zone of the yard 5 whose number corresponds to the number of a zone of the yard 3 from which they were supplied. when accumulating the remainings in the yard 5, the central part of the remainings should be positioned on the center CL of the yard 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for unloading flat bar remnants from a flat bar for accumulating cut-out remnants in a remnant unloading yard.

[0002]

2. Description of the Related Art Referring to FIGS. 3 (A) and 3 (B), in a conventional flat bar residual material unloading method, for example, 2 m of residual material A and 4 m of residual material B generated by cutting of a flat bar. When unloading 3 m of the remaining material C to the second yard of the remaining material unloading yard 101, first, the remaining material A is arranged in accordance with the reference line L, and the remaining material B is not stacked on the Are arranged at the upper side in FIG. 3 (A). Since the remaining material C is shorter than the remaining material B, the remaining material C can be stacked on the remaining material B, and is arranged on the reference line L side on the remaining material B.

[0003]

However, in such a conventional technique, the above-mentioned residual material unloading yard 101
In the case where a long remaining material such as 5.5 m is generated, it cannot be carried out because there is no place to carry out. In order to avoid such a situation, there is a problem that the remaining material unloading yard 101 must be set wide.

SUMMARY OF THE INVENTION [0004] An object of the present invention is to pay attention to the above-mentioned problems of the prior art, and to provide a flat bar remaining material discharging method capable of narrowing the remaining material discharging yard. It is in.

[0005]

According to a first aspect of the present invention, there is provided a flat bar remnant unloading method, wherein a flat bar is cut out by supplying a material from a material supply yard. In the flat bar remaining material discharging method for discharging the remaining material to the remaining material discharging yard, the remaining material discharging yard is provided corresponding to the number of the material supply yard, and at least one short dedicated yard is further provided, Among the remaining materials, the short material is stored in the short dedicated yard, and the other remaining materials are stored in the remaining material unloading yard having the same number as the number of the material supply yard in which the material from which the remaining material has been cut is stored. Accumulation.

[0006] Therefore, as for the remaining material supplied from the material supply yard and cut out of the flat bar, the short material is accumulated in the short material dedicated yard of the remaining material discharge yard, and the other remaining material is stored in the supplied material supply yard. It is stored in the remaining material unloading yard of the number corresponding to the number.

According to a second aspect of the present invention, there is provided a flat bar remaining material discharging method according to the first aspect, wherein the flat bar stores the remaining material in the remaining material discharging yard. And accumulate them in accordance with the center of the remaining material unloading yard.

Therefore, when accumulating the remaining material in the remaining material unloading yard, the center of the remaining material is aligned with the center of the remaining material unloading yard.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 and FIGS. 2A and 2B show a method of unloading flat bar residual material according to the present invention. Referring to FIG. 1, a material supply is performed in which materials are stored by being distinguished according to size, material, and the like, with a material being carried in and out of a band saw or the like (not shown) or a carry-in / out device 1 for carrying out the remaining material of a flat bar. A yard 3 and a remaining material unloading yard 5 for storing the unloaded remaining material are provided.

The material supply yard 3 has, for example, S1 to S4 yards. Further, the remaining material unloading yard 5 has one more P1 to P5 yards than the material supply yard 3, and the P1 to P4 yards have the same number of remaining materials as the material supply yard 3 from which the used material is taken out. Store long ones. The P5 yard, which is a short yard exclusively, stores all short remaining materials.

When accumulating the residual material in the residual material unloading yard 5, the center of the residual material is aligned with the center CL of the residual material unloading yard 5, as shown in FIGS. Put. For example, when 2 m of the remaining material A, 4 m of the remaining material B, and 3 m of the remaining material C are stacked in order, the center of the remaining material A is placed at the center CL of the remaining material discharging yard 5, and the center of the remaining material B is set. It is placed in alignment with the center CL of the remaining material unloading yard 5 (that is, the center of the remaining material A), and is similarly stacked with the center of the remaining material C aligned with the center CL (that is, the center of the remaining material B).

From the above results, only the short remaining material is accumulated separately in the short exclusive yard P5, and the remaining material is accumulated in the remaining material unloading yard 5 having the same number as the number of the material supply yard 3 from which the material is taken out. If the number of the remaining material discharge yards 5 is one or more than the number of the material supply yards 3, the remaining materials can be stored.

In addition, when accumulating the remaining material in the remaining material unloading yard 5, the center of the remaining material is piled up in accordance with the center CL of the remaining material unloading yard 5, so that even the long and short lengths can be stably repeated. You can pile up. This makes it possible to continuously cut the flat bar because it is not impossible to carry it out.

It should be noted that the present invention is not limited to the above-described embodiment of the present invention, but by making appropriate changes,
It can be implemented in other aspects.

[0016]

As described above, in the flat bar residual material discharging method according to the first aspect of the present invention, the flat bar cut-out residual material supplied from the material supply yard is a short-length residual material discharging method. The remaining material is stored in the short yard of the yard and the remaining material is stored in the remaining material unloading yard corresponding to the number of the supplied material supply yard. All remaining material can be accumulated by the yard. Thereby, it is possible to prevent the unloading from being impossible, and it is possible to perform the cutting process continuously.

In the flat bar residual material discharging method according to the second aspect of the present invention, when the residual material is accumulated in the residual material discharging yard, the center of the residual material is aligned with the center of the residual material discharging yard. Even if long and short remaining materials are carried out alternately, they can accumulate.
