Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a binding device for metal plate coils, and more particularly to a device for binding metal plate coils by tightening and binding them in the radial direction spanning the inner and outer circumferences of metal plate coils with straps.

Metal sheets such as steel plate coils that have undergone hot rolling or cross-rolling are wound into coils and transferred to the next process or shipped as products, but the wound coils are susceptible to loosening and the sides of both ends. It is customary to tie them together with straps to prevent them from protruding in any direction. One method of bundling the coils using such straps is to wrap the straps around the coils in a radial direction ranging from the inner circumference to the outer circumference of the coil at a plurality of locations in the circumferential direction of the coil, and then tighten and bind the coils.
In this strapping method, first, a guide chute of the strap is placed relative to the coil so that the area to be bound of the coil, that is, a radial direction extending from the inner circumference to the outer circumference of the coil is viewed outward. Send out the strap and make it go around the inside of the guide chute. Then, the tip of the strap that has gone around the strap is grasped by the strapping head, and then the ring of the strap is tightened, and when the coil is wound tightly, the front and rear ends of the strap are joined to complete the binding. In this type of coil bundling, in order to prevent damage to the corners of the coil that the strap touches, a corner protector such as cardboard is placed on the corner and the strap is hung around the corner. However, in the past, there was no suitable means for holding the corner support material, so the worker had to hold the corner support material by hand until the binding was completed.
This is a cause of impeding efficiency and work rationalization in coil bundling work. The present invention was devised to solve the above-mentioned conventional drawbacks, and it is possible to hold a corner support member without requiring any labor from the operator, and also to appropriately wrap a strap around the corner support member and bind a coil. The purpose is to provide a device that can.

Therefore, in the present invention, the coils are disposed on all sides of the support frame so as to correspond to the four corners of the part to be bound extending from the inner circumference to the outer circumference of the coil and are located on substantially the same plane.

By rotating the coils 51 and 5, the coil 1 is rotated by a predetermined angle in its circumferential direction, and the next part to be bound is positioned so as to be surrounded by the strap guide chutes 5, 5. In this state, the next bundling is performed, and by repeating the above steps, a plurality of locations around the circumference of the coil are bound. However, once all the binding is completed in this way, the strap guide chute 5 is moved backward, the support frame is raised, and the cart 8 is moved backward, and the tied coils are carried out together with the cart 52. Note that the above-mentioned operations of each cylinder device can be performed automatically based on detection of the coil position by a phototube or the like.

Further, the corner support member P is configured to have an L-shaped cross section, and may be made of an appropriate material such as a metal plate, plastic, or cardboard. In addition, the suction section 13 of the suction head 13
1 and the suction portion 241 at the tip of the conveyor village 24 may be constituted by an electromagnet, and in this case, the corner support material P is made of iron or the like.

Further, when the corner support material P is attracted by an electromagnet in this way, it goes without saying that the adsorption and delivery of the corner support material P by the adsorption parts 131 and 241 is performed by turning the electromagnet ON and OFF. According to the device of the present invention described above, it is possible not only to wrap the strap properly in the radial direction from the inner circumference to the outer circumference of the coil, but also to tighten the strap at the corners without requiring any effort from the operator. The material can be pressed and held, which has the excellent effect of improving efficiency and streamlining the work in coil binding work.
