Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a metal plate binding device for binding a plurality of thin metal plates supplied to a melting furnace, and more particularly to a metal plate binding device and a metal plate binding method for binding a copper plate mainly composed of electrolytic copper (cathode). .
[0002]
[Prior art]
2. Description of the Related Art Conventionally, when supplying a copper plate material to a melting furnace such as a shaft furnace, generally, a transfer and supply device that transfers the copper plate material by a roller conveyor or a chain conveyor and supplies (inputs) the copper plate material to the melting furnace is used. When the supply amount of the copper plate material is increased, a plurality of sheets are conveyed in a stacked manner.
[0003]
[Problems to be solved by the invention]
However, when a plurality of copper plates are transported in a stack as in the conventional case, it is difficult to control the position and the transport speed of the overlapped copper plates because the upper plate and the lower plate are easily separated during the transport. In addition, there is a problem that the transport supply device cannot be automatically operated. Further, when a device for negatively adsorbing a copper plate material is provided from above in the middle of the transport supply device for automatic operation, the copper plate material is transported one by one, which is irrational in time.
[0004]
On the other hand, it is conceivable to bind a plurality of copper plate materials with an additional material such as a band material. However, a binding machine having a complicated structure is required, and the management of the additional material for binding is increased.
[0005]
In the case of electrolytic copper, it is conceivable to bind them together by welding, but this is not reasonable because the equipment for this is very large. Further, in the case of electrolytic copper, the shape may be wavy (like a slate for a roof), but with such a wavy shape, it is more difficult to control the conveyance than a flat plate.
[0006]
The present invention has been made in view of the above point, and it is possible to bind a plurality of metal plate members in a flat state with an easy mechanism without using an additional material. It is an object of the present invention to provide a metal plate material binding device and a metal plate material binding method capable of realizing good automatic operation.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, a metal plate material binding device of the present invention includes a first plate on which a steel convex portion on which a corner portion of a plurality of stacked metal plate materials is placed is fixed to a surface, A second plate, which is arranged to face the first plate and has a cutout formed in a region facing the projection, and a corner of a metal plate material placed on the projection, A first pressing means for pressing the second board so that portions other than the bent corners come into contact with the first board, and the bending means. And a second pressing means for pressing the corner so that the corner is bent to the surface or near the surface of the metal plate.
[0008]
Further, the opposed surfaces of the first and second boards are flat surfaces.
[0009]
Further, the method of binding metal plate materials according to the present invention is characterized in that corner portions of a plurality of stacked metal plate materials are bent so that each metal plate material is bound.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0011]
(Embodiment)
FIG. 1 is a diagram illustrating a configuration of a metal plate material binding device according to an embodiment of the present invention.
[0012]
The metal plate material binding device shown in FIG. 1 includes a square (or rectangular) steel platen 1 and a steel block 3 (three corners in FIG. 1) fixed to four corners of the upper surface of the steel platen 1. ), A hydraulic cylinder 7 provided above the steel platen 1, and fixed to the tip of a shaft that moves in a vertical direction of the hydraulic cylinder 7 and directly above each steel block 3. A square (or rectangular) steel platen 5 having notches formed at the four corners of the steel platen, and a hydraulic cylinder 9 disposed slightly outside the four corners of the steel platen 1 (Only two hydraulic cylinders 9 are described) and a cylindrical metal fitting 8 fixed to the tip of a shaft that moves in the horizontal direction of each hydraulic cylinder 9.
[0013]
However, the notches at the four corners of the steel platen 5 are formed as follows. After placing a plurality of stacked copper sheet materials 2 on the steel platen 1 so that the four corners are arranged on each steel block 3, the steel platen 5 was lowered by the hydraulic cylinder 7. In this case, as shown in FIG. 2, the steel platen 5 is formed so as to press the steel platen 1 while avoiding each steel block 3. Further, by the pressing, the protrusions 4 of which the four corners of each of the copper electroplated materials 2 are bent substantially vertically protrude in the direction indicated by the arrow 12 in the axis of each hydraulic cylinder 9, so that the metal fitting 8 fixed to the tip of the shaft , And can be bent to the uppermost surface portion of the electrolytic copper plate material 2 as shown by the arrow 13.
[0014]
An operation of binding a plurality of stacked copper sheets 2 as shown in FIG. 3A by the binding device having such a configuration will be described.
[0015]
First, as shown in FIG. 1, a plurality of stacked electrical copper plate members 2 are placed on a steel platen 1 such that four corners thereof are arranged in each steel block 3. After the mounting, the shaft of the hydraulic cylinder 7 is lowered in the direction indicated by the arrow 11, whereby the electrolytic copper plate 2 is pressed by the steel platen 5 fixed to the tip of the shaft. Due to this pressing, as shown in FIG. 3B, the four corners of the plurality of stacked copper sheets 2 are bent substantially vertically, and the projections 4 are formed. At this time, the electroplated copper plate 2 is pressed against the lower steel platen 1 by the upper steel platen 5, so that each of the electroplated copper plates 2 adheres and becomes flat even if it is corrugated.
[0016]
Thereafter, as shown in FIG. 2, the shaft of each hydraulic cylinder 9 is protruded in the direction shown by the arrow 12, and the metal fitting 8 fixed to the tip of the shaft presses each projection 4, and as shown in FIG. As shown in (2), it is bent to the surface portion of the uppermost copper plate material 2. As a result, the stacked copper sheets 2 are integrated into a bundle 6 of copper sheets.
[0017]
As described above, according to the metal plate material binding apparatus of the present embodiment, a plurality of thin electrolytic copper plate materials 2 can be bound in a flat state by an easy mechanism without using an additional material. By the way, there are many thin copper sheets having a thickness of about 5 mm or less and many corrugations at present in the world market, but even if the plurality of stacked copper sheets 2 is corrugated, It can be flattened.
[0018]
When such a bundle 6 of electroplated copper materials is conveyed by a conveyance and supply device using a roller conveyor or a chain conveyor and supplied to the melting furnace, separation of the upper and lower plates does not occur during the conventional conveyance. It is easy to control the position and the transport speed of the bundle 6, and since a plurality of the bundles 6 are transported together, an efficient automatic transport operation can be realized.
[0019]
【The invention's effect】
As described above, according to the present invention, since the corners of a plurality of stacked metal plate members are bent by pressing so that the respective metal plate members are bound, the plurality of metal plate members are formed using an additional material. Instead, it can be bound in a flat state with an easy mechanism, and thereby, it is possible to realize efficient automatic operation in the transporting and feeding device for the metal plate material.
