Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for collecting and binding long materials. More specifically, after the long material cut into a predetermined length by the cutting device is bound by the small binding device in a predetermined number to make a small bundle, the small bundle is bound by the large binding device into a plurality of bundles. Concerning the gathering and binding system of scale materials.

[0002]

2. Description of the Related Art Conventionally, in the production of various long bar steels such as angle bars, H-section steels, and reinforced steel bars, hot rolling is used to form long bar materials having a total length of about 80 to 120 m, which are then cooled in a cooling field. After that, a plurality of strips are simultaneously supplied to a cutting device, and in the state where the long raw materials are arranged in parallel, a plurality of steel strips having a predetermined length are simultaneously produced by cutting by a cold shear method. Then, the above-mentioned steel bar material is automatically conveyed to the small binding device by the feeding device, bound by the small binding device by the number of cuts or by an integral multiple thereof, and then temporarily stocked in the small bundle stocking device. A predetermined number of bundles are supplied to the large bundling device by the bundle supply device, and are further bundled into a large bundle.

When cutting the long material, the total length of the long material may not be an integral multiple of the desired length of steel bar (main length material). In this case, A surplus portion will occur at the end. For this reason, the surplus portion is cut into two or three types of lengths different in length from the main scale material to produce a sub-scale material, thereby increasing the product yield. However, if the vernier scale material is supplied as it is to the bundling device, a large bundle in which the main scale material and the vernier scale material are mixed is produced, which does not meet the specifications of the user. Therefore, the vernier scale is tied separately from the main scale by one of the following methods. A manual work method in which the vernier scale material immediately after cutting is taken out from the main scale line, and when a large number of large bundles are collected, small binding and large binding are performed manually. A semi-automatic method in which the vernier scale material just after cutting is taken out from the main scale line, and when it has accumulated a large number of large bundles, it is manually supplied to the small binding device and the large binding device, and only the binding work is performed automatically. A fully automatic method in which the vernier scale material just after cutting is taken out from the main scale line and is flowed to a dedicated line having exactly the same equipment as the main scale line to automatically carry and bind the vernier scale material.

[0004]

The above method has a problem in that the binding work requires a lot of manual labor and the processing capacity is small. Also,
The method of (1) requires a small binding device and a large binding device dedicated to the vernier scale material, resulting in an increase in equipment cost and a problem that labor saving cannot be achieved despite the equipment cost. .

Further, the method (1) has a problem that a huge equipment cost as much as that of the main-scale line is required and a product cost is significantly increased. The present invention has been made in view of the above problems, and an object of the present invention is to provide a stacking and binding system for long length materials that can bind the sub-scale materials efficiently at low cost.

[0006]

In order to achieve the above-mentioned object, a long material gathering and binding system according to a first aspect of the present invention cuts a plurality of long materials arranged in parallel at predetermined intervals. Then, while producing a main length material of a desired length, the excess portion generated at the end of the long length material is cut into a length different from that of the main length material, and the main length material and the sub-scale material are individually separated. In a facility for accumulating and bundling, a small bundling device for individually bundling a predetermined number of the above-mentioned main scale material and a sub-scale material into a small bundle, and a small bundle bunched by the small bundling device for each predetermined bundle A large bundling device for producing a large bundle, and a long material supply device that automatically supplies the main scale material and the sub-scale material from the cutting device to the small binding device, and the small binding device and the large binding device. A main-scale small-bundle strike, which is provided between and temporarily stocks a small bundle of main-scale materials produced by a small binding device. And a small bundling device provided between the small bundling device and the large bundling device and temporarily stocking a small bunch of the vernier scale material produced by the small bundling device, and a main boutlet small bundle. Main scale small bundle supply device for feeding small bundles of main scale material stocked in the stocking device by a predetermined number of bundles to the large bundling device, and the main scale of the small bundles produced by the small binding device A small bundle of material is put into the main-scale small bundle stock device.
A small bundle distributing device for distributing a small bundle of the vernier scale material to the vernier scale small bundle stock device, and a small bundle of the vernier scale material stocked in the vernier scale small bundle stock device for each predetermined number of the main scale small bundles. And a vernier small bundle supply device for supplying to the supply device.

According to the second aspect of the present invention, in the long material collecting and bundling system, the vernier small bundle stock device is rotatable about a horizontal axis on which a small bundle of vernier materials is placed and stocked. The vernier small bundle supply device includes a stock arm, and the vernier small bundle supply device includes a rotation drive means for rotating the arm so that the small bundle of the vernier scale material stocked in the arm is dropped and supplied to the main scale small bundle supply device. It is a thing.

Further, in the long material gathering and bundling system according to the third aspect, the vernier small bundle stock device receives the small bundle of the vernier material dropped and supplied from the small binding device and conveys it to the stock position. It is provided with a transport conveyor that does.

[0009]

According to the above-mentioned long material collecting and binding system, the small bundle of the vernier scale material produced by the small tying device is distributed to the vernier scale small bundle stocking device by the small bundle distributing device. The stocked small pieces of the vernier scale material can be supplied to the main scale small bundle supply apparatus by a predetermined number of bundles by the vernier scale small bundle supply apparatus. The bundle can be supplied to the large binding device by the main-measure small-bundle feeding device to be bound into a large bundle. Therefore, the vernier scale materials can be automatically bundled without using a binding device dedicated to the vernier scale materials.

According to the second aspect of the present invention, the stock arm of the vernier small bundle stock device is rotated about the horizontal axis by the rotation driving means of the vernier small bundle feeding device. Only by this, a small bundle of the vernier scale material stocked in the vernier scale small bundle stock device can be dropped and supplied to the main scale small bundle supply device. According to the long material collecting and bundling system of claim 3, the small bundle of the sub-scale material is simply dropped from the small binding device onto the conveyor, and the small bundle is stocked in the sub-scale small bundle stocking device. be able to.
