Description

  The present invention relates to a peeling apparatus and a peeling method for a deposited metal plate such as a pure copper plate deposited from an electrolytic cell.

  For example, in the electrolytic refining of copper called the ISA method, a direct current is passed from a crude copper anode to a cathode made of a stainless steel plate in a copper sulfate solution in an electrolytic cell using a stainless steel plate cathode. The copper content is dissolved and transferred to the cathode, and pure copper is deposited on both sides of the cathode plate (for example, Patent Document 1).

FIG. 7 shows a cathode 2 of a stainless steel plate that has been conventionally used.
In this cathode 2, in order to facilitate the removal of the pure copper plate to be deposited, a V-shaped groove 4 is formed on the lower end surface of the plate-like portion 2a, and the upper edge and both side edges of the plate-like portion 2a. In addition, a band plate 6 made of an insulating material such as plastic is disposed, and this band plate 6 prevents pure copper from being deposited on the upper edge portion and both side edge portions of the plate-like portion 2a.

  The cathode 2 of such a stainless steel plate is alternately arranged in an electrolytic cell filled with an electrolyte together with an anode made of crude copper or an anode as a mere electrode, and pure copper is deposited on the surface of the cathode 2 by flowing an electric current. It is deposited. When the cathode 2 reaches a certain weight, the cathode 2 is pulled up from the electrolytic cell, and as shown in FIG. 8, pure copper plates (hereinafter simply referred to as copper plates) 8 and 8 deposited on both surfaces are peeled off from a scraper or the like. It is peeled off by the machine 10.

  As this stripper 10, the plate-shaped wedge member 10 by which the front end side was formed in the taper shape can be illustrated. Such a wedge member 10 is supported by a shaft or an arm and is arranged to be movable up and down with respect to the plate-like portion 2a of the cathode 2.

When such a pair of wedge members 10 are inserted into a gap in the upper part of the plate-like portion 2a and the copper plate 8 and moved downward, the flat copper plates 8 and 8 are formed on both sides as shown in FIG. Expanded.
Special table 2002-531697

  By the way, in such a conventional method, depending on the electrolysis conditions or the like, even a pair of copper plates 8 and 8 that are tilted horizontally on both sides are not separated into two as shown in FIG. It may still be merged into one sheet. In such a case, the pair of copper plates 8 and 8 are gripped by the grips 12 and 12 to return to the original upright posture, and tilted again in the horizontal direction, and such an operation is repeated as necessary. Thus, fatigue failure is caused in the connection portion of the copper plate 8, and then the grip 12 is pulled in a substantially horizontal direction as indicated by an arrow so as to promote separation of the copper plates 8 and 8.

  However, such a peeling apparatus has a problem in that the structure for separating the copper plates is complicated, and when a similar peeling apparatus is applied to an apparatus having a small processing capability, the cost increases.

  In view of such a situation, the present invention is not separated into two pieces in a normal operation in which two copper plates are developed in a substantially horizontal state, and the copper plates are still combined into one piece. It aims at providing the peeling apparatus and peeling method of the deposit metal plate which can be reliably isolate | separated into 2 sheets with an easy structure.

In order to achieve the above object, the apparatus for separating a deposited metal plate according to the present invention comprises:
A device for peeling a deposited metal plate for stripping a pair of deposited metal plates deposited on both sides of a cathode electrode in an electrolytic cell from the cathode electrode,
On the upper side of the cathode electrode, a wedge member that can move up and down and extends in the horizontal direction, and an auxiliary pressing member that can move up and down and have a larger diameter than the wedge member,
The wedge member is inserted from the gap formed between the cathode electrode and the deposited metal plate to move the wedge member downward, and the auxiliary pressing member is inserted to the gap to move downward,
The two deposited metal plates are peeled off from the cathode electrode by the movement of the wedge member and the auxiliary pressing member.

  According to such a peeling apparatus, the pair of deposited metal plates are separated from the cathode electrode by the auxiliary pressing member as well as the wedge member. The plates can be separated from each other. Moreover, the structure is easy.

Here, in the present invention, on the lower side of the cathode electrode, while installing a flapper that can be tilted repeatedly from a laid posture, or from a standing posture to a laid posture,
When the connection portion of the pair of deposited metal plates is not separated, it is preferable that the connection portion of the deposited metal plate is separated by repeatedly tilting the flapper in a standing posture or a lying posture.

With such a structure, it is possible to cause metal fatigue at the connection portion of the deposited metal plate, thereby separating the deposited metal plate into two.
Moreover, the peeling method of the deposit metal plate which concerns on this invention is the following.
A method for peeling a deposited metal plate for peeling a pair of deposited metal plates deposited on both sides of a cathode electrode in an electrolytic cell from the cathode electrode,
A gap forming step of forming a gap at an upper meeting portion between the cathode electrode and the deposited metal plate;
A metal plate widening step in which a wedge member is inserted into the gap obtained in the gap forming step from above and the lower side of the deposited metal plate is widened in a V shape;
A metal plate unfolding step in which an auxiliary pressing member is inserted into the gap obtained in the metal plate widening step and the deposited metal plate rolls over in a substantially horizontal state in accordance with the widening operation of the V-shaped gap;
Metal plate bending step of separating the pair of deposited metal plates by repeatedly tilting the deposited metal plate from a laid posture or from a standing posture to a laid posture after the metal plate unfolding step It is characterized by having.

If the deposited metal plate is peeled by such a method, even if two deposited metal plates are connected, the connection can be easily cut.
In the peeling method according to the present invention, it is preferable that the metal plate bending step is performed by a tilting operation of a flapper disposed on the lower side of the cathode electrode.

With such a method, the deposited metal plate can be automatically rolled over via the flapper.
Here, it is preferable that the metal plate bending step is performed in a state where the wedge member and the auxiliary pressing member are retracted above the cathode electrode.

  In this way, the wedge member and the auxiliary pressing member are out of the swinging range of the deposited metal plate, and therefore do not interfere with the swinging of the deposited metal plate.

According to the apparatus and method for peeling a deposited metal plate according to the present invention, two deposited metal plates can be peeled from the cathode and reliably separated one by one.
Furthermore, since the structure for pulling the deposited metal plate in the horizontal state to both sides is unnecessary, the structure is compact.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a cathode 20 employed in an apparatus for peeling a deposited metal plate (copper plate) according to an embodiment of the present invention. FIG. 2 shows an action when peeling a copper plate 28 deposited on both surfaces of the cathode 20. It is a schematic sectional side view which shows.

  In the cathode 20, a rectangular plate-like portion 20 a made of stainless steel is attached to a horizontal support member 22 called a hanger in a posture that hangs down in the vertical direction. Further, a V-shaped groove 24 is formed on the lower end surface of the plate-like portion 20a, and when the groove 24 is formed, the copper plates 28 and 28 deposited on both sides are peeled off by a method described later. It can be easily peeled off.

  On the other hand, strips 26 made of an insulating material are disposed on both side edges (including end faces) of the plate-like portion 20a of the cathode 20, and the strips 26 prevent pure copper from being deposited on both side edges. Yes. In FIG. 1, only one side of the cathode 20 is shown, but the opposite side has the same configuration.

The peeling device 30 for stripping the copper plates 28 and 28 shown in FIG. 2 from the cathode 20 is mounted on equipment such as a large steel plate as shown in FIG.
In the peeling apparatus 30 of the present invention, the wedge member 38 shown in FIG. 2 moves from the upper side of the copper plate 28 toward the lower side, thereby expanding the lower side of the copper plate 28 in a V-shape. A metal plate unfolding step for unfolding the copper plate 28 in a substantially horizontal state by inserting and lowering the lower end of the auxiliary pressing member 40 into the upper gap obtained in the metal plate widening step; When two copper plates 28 developed in a substantially horizontal state in the development process are still connected to one piece, in order to separate them, the copper plate 28 is laid from the laid posture or laid from the laid posture. And a metal plate bending step for repeatedly performing the tilting operation to the predetermined posture are provided in this order.

  That is, as shown in FIG. 3, V-shaped mounting portions 32 for supporting the hangers of the cathode 20 are respectively installed on the upper portions of a pair of support columns 34 made of large steel plates. Further, both ends of the cathode 20 on which the copper plate is deposited are supported.

  The peeling apparatus 30 according to the present embodiment is configured symmetrically on both the front and back surfaces with respect to the cathode 20. That is, in order to surely peel off the copper plate 28, in addition to the pair of wedge members 38 shown in FIG. 3, the pair of auxiliary pressing members 40 shown in FIG. 4 and the pair of flappers 50 shown in FIG. I have.

  And the metal plate expansion process by the auxiliary | assistant press member 40 is implemented with the metal plate expansion process by the wedge member 38, and also the metal plate bending process by the flapper 50 is implemented.

  As shown in FIG. 2, the wedge member 38 and the auxiliary pressing member 40 are installed so as to be movable up and down with respect to the cathode 20, but the flapper 50 is configured as shown in FIGS. As shown in FIG. 5, the cathode 20 is installed so that it can be tilted (expanded) so as to be either in a standing position or a lying position.

  In the peeling device 30 having such a configuration, force is applied alternately from a direction substantially perpendicular to the plate-like portion 20a of the cathode 20 before performing the metal plate widening process by the wedge member 38. A slight gap is secured between the plate-like portion 20a and the copper plate 28 in the upper portion of the plate-like portion 20a. Thereby, a gap for the entrance of the wedge member 38 is formed.

  In the state of FIG. 3, the wedge member 38 has its tip end portion 38a located approximately in the middle of the height direction of the copper plate 28. In actual operation, the wedge member 38 is moved upward from the position of FIG. It is set as an initial position, and the front-end | tip part 38a is orient | assigned to the copper plate 28 side, and is inserted in the clearance gap between the copper plate 28 and the plate-shaped part 20a. Further, the angle adjustment of the distal end portion 38 a of the wedge member 38 is performed by the rotation operation of the shaft 39.

  On the other hand, the auxiliary pressing member 40 that follows the downward movement of the wedge member 38 is used to further ensure the peeling by the wedge member 38. As shown in FIG. The end side is formed thick. The shape of the auxiliary pressing member 40 can be exemplified by a rod-shaped member having a cross-sectional beak shape having a thick base end side as shown in FIG. 4, but is not limited to this shape. It may be configured.

  The auxiliary pressing member 40 is guided downward in the same manner as the wedge member 38 with a slight delay after the wedge member 38 is moved downward. As a result, as shown in FIG. 2, after the copper plate 28 is opened on both sides at the front end portion 38 a of the wedge member 38, the rear side can be further separated by the auxiliary pressing member 40. Then, the auxiliary pressing member 40 moves downward with the copper plate 28 wide open. When the auxiliary pressing member 40 approaches the vicinity of the bottom end, the auxiliary pressing member 40 overtakes the wedge member 38 that has already stopped moving, and only the auxiliary pressing member 40 moves the copper plate 28. The copper plate 28 is pressed against the pedestal 33. Thereby, the copper plate 28 is developed in a substantially horizontal state.

Furthermore, in this embodiment, as shown in FIGS. 5A and 5B, the flapper 50 is provided on the back side of the copper plate 28.
The flapper 50 is supported so as to be rotatable (tiltable) on both sides about the rotation shafts 52, 52, and is constituted by a pair of frame-shaped frame plates 54. In addition, a holding plate 56 is provided at the distal end portion of the frame plate 54.

  As shown in FIGS. 5A and 5B, such a flapper 50 can repeatedly perform a tilting operation in which the flapper 50 is erected or laid from a standing posture. With the movement of the flapper 50, the copper plates 28, 28 that have not yet been separated can be brought into a standing posture from a sleeping posture or a standing posture from a standing posture. In FIG. 5A, although one frame plate 54 of the flapper 50 is shown in a standing posture and the other frame plate 54 is laid down, it actually operates in the same posture.

Although the peeling apparatus 30 according to the present embodiment is configured as described above, the operation will be described below.
First, the cathode 20 on which the copper plates 28 are deposited on both sides in the electrolytic cell is set between the mounting portions 32, 32 of the equipment machine shown in FIG. In this state, a gap is not yet formed between the copper plate 28 and the plate-like portion 20a of the cathode 20. From this state, first, a force is applied to the copper plate 28 from a horizontal direction perpendicular to the cathode 20 to bend the copper plate 28, thereby forming a gap between the copper plate 28 and the plate-like portion 20a. A structure in which a slight gap is formed between the copper plate 28 and the plate-like portion 20a by applying a force from the horizontal direction as described above is known, and the contact plate is reciprocated in the horizontal direction by an arm or the like.

  On the other hand, in the initial state in which the cathode 20 is mounted on the mounting portion 32, the wedge member 38 and the auxiliary pressing member 40 are positioned above and are on standby at that position. Further, the flapper 50 is located in a state of being developed on both sides as shown in FIG.

  From this state, first, the tip end portion 38a of the wedge member 38 is guided into the gap between the copper plate 28 and the plate-like portion 20a. And the front end side is gently guided downward. Then, the copper plate 28 is gradually peeled off. Furthermore, in this embodiment, the auxiliary pressing member 40 is guided downward so as to follow the movement of the wedge member 38.

  As the auxiliary pressing member 40 is guided downward, the gap between the copper plate 28 and the plate-like portion 20a is gradually increased as shown in FIG. 2, so that the copper plate 28 is surely separated from the plate-like portion 20a. Is done. Then, as shown in FIG. 6, when the copper plate 28 is deployed on both sides to a level close to a substantially horizontal state, the auxiliary pressing member 40 overtakes the wedge member 38, and the copper plate 28 is removed only by this auxiliary pressing member 40. Press.

  Here, when the copper plates 28 on both sides are still connected in the developed state, the wedge member 38 and the auxiliary pressing member 40 are returned to the initial positions and the flapper 50 is operated. When the flapper 50 is actuated, the frame plates 54 on both sides press the back side of the copper plates 28, 28 upward, that is, so as to erection, so that the posture in which the copper plate 28 is laid down is changed to a standing posture. When the copper plate 28 is returned to the standing posture as described above, the wedge member 38 and the auxiliary pressing member 40 are actuated again to deploy the copper plate 28 downward. The second operation may be performed only by the auxiliary pressing member 40. When the copper plates 28 and 28 are placed in the horizontal position, the flapper 50 is activated again to raise the copper plate 28. By repeatedly performing such a tilting operation of the flapper 50, metal fatigue is caused and the two copper plates 28, 28 can be reliably separated.

When the two copper plates 28 can be separated only by the operations of the wedge member 38 and the auxiliary pressing member 40, the opening / closing operation of the flapper 50 can be omitted.
In this way, the two copper plates 28 can be reliably separated from the cathode 20 and the lower end portion of the copper plate 28 can be reliably separated.

  As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all. For example, the deposited metal is not limited to a copper plate, and even zinc can be favorably applied.

  Moreover, the stainless steel plate as a cathode is not limited to the stainless steel plate 20 shown in FIG. 1, The stainless steel plate 2 of FIG. 7 used conventionally may be applied, and is not limited at all.
