Abstract

PURPOSE:To automatically cut a rod member efficiently by continuously cutting said member into plural parts having different length and distributing and storing the members having an equal length and the residual material into respective specific positions in a storage board. CONSTITUTION:A distribution storage apparatus 40 is constituted of a storage belt conveyor 41, conveyor transferring motor 43, distribution part which moves a positioning mechanism 30 horizontally or turns it clockwise/counterclockwise by a link mechanism 44, and a storage board 45. A positioning stopper plate 35 is raised by the operation of a cylinder 33, and cut rod is pulled-out from a cutter 20 by driving the conveyor 41, and said cut rod is received by a distributing stopper plate 36, and the storage conveyor 41 is tilted rightward or leftward by the link mechanism 44 and thrown onto the storage board 45.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cutting a long bar into a constant length.

2. Description of the Related Art Conventionally, as an automatic cutting method for cutting long bars such as reinforcing bars into a certain length, it is known to use a bar strip supply device and a cutting machine.

However, it is only necessary to connect each device to continuously cut a single bar to a certain length, which requires positioning for each dimension, which is time-consuming and produces residual material with a considerable length. However, it is difficult to say that the use of equally efficient equipment is uneconomical.

Therefore, the present invention aims at cutting and storing the bar by continuously cutting a single bar into a plurality of pieces with different dimensions, and storing the cut pieces of the same size and the remaining pieces in a specific position on the pr-storage stand. By adopting this method, efficient cutting work can be performed automatically.

The present cutting and storing method will be explained below based on the drawings.

FIG. 1 is a longitudinal cross-sectional view of a horizontal storage device in which a storage device is arranged, which has four supply devices, a cutting machine J, and a positioning mechanism (1).

The material supply device tOQ is provided with a tape conveyor 00 extending in the longitudinal direction, and a supply belt drive motor (4e) supplies the bars from the material table @ to the cutting machine.

The α role is the belt support roller. It consists of a clamp mechanism for fixing the rod assembly pushed through the cutting machine 1 and a cutting blade, and is operated by the respective driving bodies.

The positioning mechanism (7) is distributed to the side frame t of the storage device (to)
When the positioning chain 5D and this is installed,
The storage belt conveyor (40) of the storage device lfO and the cylinders (G) (B) L are placed at regular intervals on the frame frame with a gap that allows the rods to pass through. The positioning abutment plate (to) that comes into contact with the moving rod group and the swing part are such that the abutment plate (to) is hanging down.

Also, the positioning chain 6B is a positioning motor (b).
t thus drives the frame 621 to move.

As for distribution, the storage belt conveyor is rotatably attached to the support shaft '→, the motor for moving the storage conveyor, and the positioning mechanism (1) are moved horizontally or horizontally by the link mechanism θ→. The swing part that allows the swing to rotate is made up of a part, and the swing part is made up of a storage stand (c) arranged at the left and right bottom of the part. And, the locking position of the swing portion is the rotating plate θ of the link mechanism →
The amount of rotation, which is the source of rotation of the rotation axis of @, is determined by the motor θ.

With such a device, first, the material is dropped onto the belt conveyor a0 of the material supply device σQ from the material stage, and the positioning motor (9) of the positioning mechanism (1) is activated to move the frame (support). Set the distance between the cutting blade and the positioning plate (G) to a predetermined length. In this case, the positioning plate (c) and the distribution plate (2) are both in a lowered state and are shielding the top of the storage belt conveyor (goods).

Then, the supply belt drive motor (B) is activated to transport the belt conveyor συ, and after the bar passes through the cutting machine (1) and is conveyed until it comes into contact with the positioning plate (to) 1, the supply belt is supplied. The operation of the belt drive motor A-way is stopped, and the clamping mechanism and cutting blade are lowered to finish cutting a certain length.

Next, the positioning plate is raised by the operation of cylinder 3, and the storage conveyor is moved by the conveyor moving motor +43 to pull out the cutting rod from the inside of the cutting machine. After stopping the receiver, the distribution is carried out by operating the motor assembly 7) and moving it to the storage conveyor C using the link mechanism.
D is tilted to the right or left and dropped onto the storage platform (G) for storage.

Further, the cutting operation is carried out with the position of the positioning plate (G) kept as it is, and the cut materials of the same length are stored in the same place on the storage table (C).

Next, move the position of the positioning plate (7) to obtain a cut material of a different length than before, and this time, rotate the motor θ in the opposite direction to the left or right for the distribution. The process of dropping it onto the storage stand ■ and storing it there is repeated several times.

After that, the remaining materials that no longer reach a certain length are raised by the positioning plate (■) and the distribution plate (to), and transported to the leading edge by the storage belt conveyor (41), where they are dropped and stored on the storage platform (c). It is.

If the operation of each power source that performs the above series of operations is set in advance and stored in the control panel, efficiency will be increased automatically.
:<Able to perform cutting work.

As shown above, according to the method of the present invention, a single rod can be cut into multiple pieces of the same size without waste, and the left and right, front and rear sides of the storage platform can be used to cut pieces of the same size. Since the allocated amount was stored for each time, subsequent work is easy and there is an advantage that the stored impregnation can be fully utilized. In addition, leftover materials are stored in one place, making it convenient to organize and reuse.
Compared to the conventional method of cutting only one bar to the same size, this method makes it possible to make maximum use of the cutting system, allows efficient cutting of bars, and also facilitates post-processing. This is a highly effective invention.
