Description

  The present invention relates to an electrodeposited metal stripping method and a brazing apparatus used therefor, and more specifically, an electrodeposited metal stripping method for stripping an electrodeposited metal from a cathode plate having a metal electrodeposited on its surface by electrolytic smelting. And a brazing device used therefor.

  Electrolytic smelting of metals using permanent cathodes (PC) by ISA, for example, electrolytic smelting of copper, includes a large number of stainless steel cathode plates (cathode plates) and crude copper in an electrolytic cell in which an electrolytic solution is stored. It is carried out by electrodepositing electrolytic copper 2 on both surfaces of the cathode plate by alternately immersing and energizing the anode plate (anode plate) in which is cast. Then, the electrolytic copper 2 electrodeposited on the surface of the cathode plate is stripped off by a stripping device to obtain a product. Specifically, as shown in FIG. 1, the cathode plate 1 is a plate-shaped material made of stainless steel, and a protector 5 made of synthetic resin is fitted on both side portions thereof, and a cross bar 4 is provided on the upper end portion. It has been. In addition, two windows 3 and 3 are provided at the lower part of the crossbar 4. By hooking the window plates 3 and 3 with a hook of an electrode plate conveying device (not shown), Removal and conveyance are performed. The cathode plate 1 made of stainless steel is widely used in recent years because it is strong and can be used repeatedly, and because of its good flatness, it has the advantage that short-circuiting during electrolytic smelting is less likely to occur. And the electrolytic copper stripped off from both surfaces of the cathode plate 1 is carried by a transport device as a set of two sheets, in order to give a flat press to ensure flatness, and to give unevenness that corrugated electrolytic copper Corrugation will be performed and provided as a product.

  Conventionally, the electrodeposited metal has been stripped as shown in, for example, Japanese Patent Application Laid-Open No. 2006-274299 (Patent Document 1). That is, the cathode plate pulled up from the electrolytic cell is washed in the washing chamber while being transported, and then transferred to the traverse conveyor by the transfer machine. Then, as shown in FIG. 2, the cathode plate 1 is held upright on the base 120 of the stripping device (FIG. 2A), and both sides of the cathode plate 1 are pressed from the left and right by the pressing tool 36. (FIG. 2 (b)) causes a difference in distortion between the cathode plate 1 and the electrodeposited metal 2 and creates a gap between the cathode plate 1 and the electrodeposited metal 2 (flexing). The electrodeposition metal 2 is peeled off (chiseling) from the cathode plate 1 by inserting and dropping 35 (FIG. 2 (c)), and the grip 37 is attached to the peeled electrodeposition metal 2 to contact the base 120. The electrodeposited metal 2 is peeled off from the cathode plate 1 by laying down (down-ending) with the bottom as a base point (FIG. 2 (d)). If the electrodeposited metal is not broken and cannot be separated from the cathode plate by the down-ender, the electrodeposition metal is further caused to “flapping” to fall again, thereby separating the two.

  As such a conventional peeling apparatus, there exists a thing shown by Unexamined-Japanese-Patent No. 2001-81591 (patent document 2), for example. This stripping device includes an insulating protector removing device that removes a part of the insulating protector attached to the end of the cathode plate, a cathode plate that is fixed in place at the position of the removed insulating protector, and an electric power source. A plurality of vacuum suction pads inserted between the electrodeposited metal and the edge of the electrodeposited metal separated from the cathode plate to open and adsorbed by the electrodeposited metal to move the electrodeposited metal in the stripping direction It is configured with. Then, a chis blade is pushed between the surface of the cathode plate and the edge of the electrodeposited metal, the electrodeposited metal is peeled off from the cathode plate by the wedge action of the wedge-shaped chis blade, and the edge of the electrodeposited metal is opened. And The electrodeposited metal in an open state is adsorbed by a plurality of vacuum suction pads and separated from the cathode plate (flapping) to peel off the electrodeposited metal.

  However, until now, since the base on which the cathode plate is placed has been flat, the angle of the electrodeposited metal lying down by the down-ender when stripping the electrodeposited metal from the cathode plate is a maximum of 90 ° with respect to the cathode plate. In some cases, the electrodeposited metal may not be completely removed in one operation, and flapping has to be performed once to several times. It is possible to peel the electrodeposited metal from the cathode plate by one or more flappings, but flapping means that extra time is taken and processing per hour is performed. There was a problem that the amount would decrease. Specifically, if stripping of the electrodeposited metal is completed without flapping, it is completed in about 7 seconds per sheet. Therefore, an average of 4,000 to 5,000 strips can be removed in an operation of about 8 to 10 hours per day. Since it takes about 2 seconds to flapping once in a series of stripping operations, the number of processed sheets per day is reduced if flapping is repeated several times on one cathode plate, and the operation efficiency is reduced. Will be affected.

  Therefore, the applicant has provided protrusions on both sides of the base on which the cathode plate is placed, and at least the electrode by contacting the lower surface of the electrodeposited metal that has been peeled off while the cathode plate is laid down on the protrusion. By providing a stripping device for electrodeposited metal which is laid down until the upper edge portion of the deposited metal is positioned below the projection, thereby separating the electrodeposited metal from the cathode plate. Invented and patented an electrodeposited metal stripping device that can complete a series of operations when stripping the electrodeposited metal from the cathode plate such as flexing, chiseling and down-end without flapping. An application was filed (Japanese Patent Application No. 2006-266326).

JP 2006-274299 A JP 2001-81591 A

As described above, according to the electrodeposited metal stripping apparatus invented by the applicant of the present application, it is possible to achieve efficient stripping of the electrodeposited metal without flapping.
However, from the state in which a gap is generated between the cathode plate 1 and the electrodeposited metal 2 by flexing (FIG. 2B), until the chisel is actually inserted and the electrodeposited metal is peeled off. In some cases, the electrodeposited metal is brought into close contact with the cathode plate again, causing a trouble that the gap into which the chisel is to be inserted is closed. For this reason, since chiseling cannot be performed, the electrode plate has to be returned to the flexing process, which has been one of the causes of a reduction in work efficiency. Stripping of electrodeposited metal is usually completed in about 7 seconds per sheet. Accordingly, since an average of 4,000 to 5,000 strips are processed in an operation of about 8 to 10 hours per day, if it takes time for one cathode plate, the number of processed sheets per day is reduced. It will be less and will naturally affect operational efficiency.

  Thus, the present invention prevents the open electrodeposition metal from coming into close contact with the cathode plate again, closing the gap between the cathode plate and the electrodeposited metal and preventing the insertion of the chisel, and ensuring that the chisel is secured. It is an object of the present invention to provide an electrodeposited metal stripping method that can be inserted and a brazing device used therefor.

In order to solve the above-mentioned problem, the present invention described in claim 1 is a method for stripping an electrodeposited metal from a cathode plate having a metal electrodeposited on the surface thereof by electrolytic smelting. Before the peeling step of inserting and peeling the chisel between the cathode plate and holding the predetermined portion on the lower side of the cathode plate on which the metal placed on the base is electrodeposited by the lower guide from both sides, An upper guide is arranged at a position on the upper side of the electrodeposited metal that is to be brazed at a position slightly spaced from the surface of the electrodeposited metal, and the center of the electrodeposited metal is pressed from the left and right by pressing members. This creates a gap between the electrodeposited metal and the cathode plate, inserts a brazing member into the gap, and inserts the chisel by bending the upper side of the electrodeposited metal outward with the upper guide as a fulcrum. To make gaps easier Characterized in that a shaping step of holding.

In order to solve the above-mentioned problem, the present invention according to claim 2 is the brazing apparatus used in the electrodeposited metal stripping method according to claim 1 , wherein the electrodeposited metal placed on the base is electrodeposited. A lower guide that holds a predetermined portion of the lower side of the cathode plate from both sides, and an electrodeposited metal on the upper portion of the cathode plate on which the electrodeposited metal placed on the base is electrodeposited The upper guide disposed at a slight distance from the surface of the electrode, and the electrodeposition metal and the cathode by pressing from the left and right near the center of the cathode plate on which the electrodeposited metal placed on the base is electrodeposited It is inserted into the gap formed by opening the plate and the gap between the pressing member that generates the gap between the electrodeposited metal and the cathode plate, and the upper side of the electrodeposited metal is bent using the upper guide as a fulcrum. To secure a gap to facilitate the insertion of the chisel Characterized by comprising a only member.

  According to the electrodeposited metal stripping method according to the present invention, the upper side of the electrodeposited metal is bent outward before the peeling step in which the chisel is inserted between the electrodeposited metal and the cathode plate and peeled off. By providing a brazing process that opens a gap between the cathode plate and thereby ensuring a gap for easy insertion of the chisel, the chisel can be securely inserted between the cathode plate and the electrodeposited metal. It is possible to perform the chiseling operation continuously.

  Further, according to the brazing apparatus according to the present invention, the predetermined portion on the lower side of the cathode plate on which the electrodeposited metal placed on the base is electrodeposited is held by the lower guide from both sides and placed on the base. The electrodeposited metal was placed on the base by placing an upper guide at a position slightly spaced from the surface of the electrodeposited metal in the upper part of the electrodeposited cathode plate and to be brazed. The electrodeposition metal and the cathode plate are opened by pressing the vicinity of the center of the cathode plate with electrodeposited metal from the left and right to open the electrodeposition metal and the cathode plate, and a brazing member is inserted into the gap. By doing so, since the gap for facilitating the insertion of the chisel is secured by bending the upper side of the electrodeposited metal with the upper guide as a fulcrum, there is an effect that the opened gap is not blocked. Therefore, the chiseling operation can be performed continuously without being hindered.

  Hereinafter, an electrodeposited metal stripping method according to the present invention and a brazing apparatus used therefor will be described in detail with reference to the drawings. 3 is a front view of an embodiment of a brazing device according to the present invention, FIG. 4 is a side view thereof, and FIG.

  The illustrated brazing device 10 is arranged in a pre-process of the stripping device for stripping the electrodeposited metal 2, and as a general rule, four struts 12 erected on a gantry 11 placed on the floor G A frame structure is formed by the horizontal beams 13 that connect them in the horizontal direction, and a base 20 on which the cathode plate 1 on which the electrodeposited metal 2 is electrodeposited is placed in an upright state is disposed at the approximate center of the frame. . And the lower guide 21 is arrange | positioned in the right-and-left two places in the immediate upper part of the base 20, respectively. The lower guide 21 is movable in the left-right direction in FIG. 4 by a hydraulic cylinder (not shown), and firmly holds the lower side of the cathode plate 1 placed on the base 20 from the left and right. ing.

  Further, on the upper side of the lower guide 21, pressing members 23 are arranged at two positions on the left and right sides, respectively, and the vicinity of the substantially central portion of the cathode plate 1 placed on the base 20 can be pressed from the left and right. It is like that. As shown in FIG. 5, the pressing member 23 is movable in the left-right direction in FIG. 5 by a hydraulic cylinder 23 a. The pressing member 23 presses the vicinity of the central portion of the cathode plate 1 from the left and right by the pressing member 23. The upper side of the metal deposit 2 is peeled off from the cathode plate 1 and opened, and a brazing member 29 described later is inserted there. As shown in FIG. 5, the pressing member 23 can be adjusted in angle with respect to the cathode plate 1 placed on the base 20 at an angle of ± 10 ° with respect to the moving direction. Yes.

  Further, on the upper side of the pressing member 23, upper guides 25 are arranged in two places on the left and right sides. The upper guide 25 is movable in the left-right direction in FIG. 4 by a hydraulic cylinder (not shown), and is located on the upper side of the cathode plate 1 placed on the base 20 and in the vicinity of the portion to be brazed. It is supposed to be located. Then, the electrodeposited metal 2 is brought into contact with the upper guide 25 by inserting it into a gap in which a brazing member 29 described later is formed, and the upper portion of the electrodeposited metal 2 is bent using the upper guide 25 as a fulcrum. This prevents the electrodeposited metal 2 from coming into close contact with the cathode plate 1 again.

  A brazing member 29 that is inserted into a gap on the upper side generated between the cathode plate 1 and the electrodeposited metal 2 by the pressing member 23 is provided on the lateral beam 13 on the upper side of the base 20. By inserting a brazing member 29 into the upper gap formed between the cathode plate 1 and the electrodeposited metal 2 by the pressing member 23, the upper side of the electrodeposited metal 2 is placed outside with the upper guide 25 as a fulcrum. A clearance for facilitating the insertion of the chisel of the peeling device is secured by folding the sheet and bending it. As a result, it is possible to prevent a problem that the electrodeposited metal comes into close contact with the cathode plate again and the gap into which the chisel is to be inserted is closed.

  The brazing member 29 is attached to the lower side of a guide bar 29b that guides movement in the vertical direction, and the guide bar 29b is formed to move up and down by a hydraulic cylinder 29a. As a result, the brazing member 29 is movable up and down. The brazing member 29 has a wedge shape with a substantially right-angled triangular cross-section that is sharpened gradually toward the distal end side, and is inserted into the gap between the electrodeposited metal 2 and the cathode plate 1 to be lowered. The upper side of the electrodeposited metal 2 is bent by being pressed and pressed. Thus, since the brazing member 29 bends the upper side of the electrodeposited metal 2, it is preferable to form it with a hard material. In this embodiment, it is formed of SUS304.
