Description

  The present invention relates to an electrodeposited metal stripping device, and more particularly to an electrodeposited metal stripping device that strips the electrodeposited metal from a flat cathode on which the electrodeposited metal is adhered.

  2. Description of the Related Art Conventionally, electrolytic refining of a metal such as copper is known in which an electrolysis tank filled with an electrolytic solution is energized in a state where cathodes and anodes are alternately arranged and metal is electrodeposited on both sides of the cathode (for example, , See Patent Document 1). In such metal electrolytic refining, a thin plate made of stainless steel or the like is generally used as a cathode that can be repeatedly used for the cathode, and the metal electrodeposited on both sides of the cathode is peeled off after being lifted from the electrolytic cell. .

  A conventional method for stripping an electrodeposited metal will be described with reference to the drawings. FIG. 1 is a schematic view showing a state of the cathode 10 that has been electrodeposited and pulled up from the electrolytic cell. The cathode 10 is a plate member made of stainless steel. Resin edge covers 20 are fitted into both side portions of the cathode 10. A beam 30 for suspending the cathode 10 from the electrolytic cell is provided on the upper portion of the cathode 10.

  In addition, two rectangular holes 40 are provided in the lower part of the beam 30, and a hook of a conveying device for the cathode 10 is hooked on the rectangular holes 40 to convey the electrolytic cell to the electrolytic cell. An electrodeposited metal 50 that is electrolytically purified is formed on both sides of the cathode 10 in a state of being pulled up from the electrolytic cell.

  FIG. 2 is a view showing a state in which the cathode 10 is attached to a transfer device used in a conventional electrodeposition metal peeling method. In FIG. 2, the cathode 10 is placed on the transport rail 90, both surfaces of the beam 30 are supported by the transport guide 110, and the lower portions of the edge covers 20 on both side portions are fixed by a U-shaped fixture 160. . By such a conveying device, the material is conveyed in a direction parallel to the cathode surface, and is once stopped in front of a flexing device provided in the same line.

  FIG. 3 is a view showing a conventional electrodeposition metal peeling process using a flexing apparatus. FIG. 3A is a view showing a state in which the cathode 10 on which the electrodeposited metal 50 is formed is installed in the flexure apparatus. As shown in FIG. 3A, a flexing pressing tool 82 and an electrodeposited metal pressing tool 120 are provided on both surfaces of the cathode 10 on which the electrodeposited metal 50 is formed. The flexing pusher 82 is provided at a substantially central portion of the surface of the cathode 10 and has, for example, a cylindrical shape with a diameter of 50 mm and a horizontal length of 500 mm. The electrodeposited metal presser 120 is provided on the upper side of the electrodeposited metal 50 and has, for example, a cylindrical shape having a diameter of 50 mm and a horizontal length of 1200 mm.

  FIG. 3B is a diagram showing an electrodeposited metal partial peeling step using the flexing pusher 82. As shown in FIG. 3B, the vicinity of the center of the cathode 10 is pushed in by about 50 mm by the flexing pusher 82. At this time, the cathode 10 is curved like a bow, and the upper side of the electrodeposited metal 50 on the convex surface side of the cathode is peeled off. The electrodeposited metal presser 120 plays a role in preventing the electrodeposited metal 50 from peeling off from the anode 10 due to excessive peeling when the upper side of the electrodeposited metal 50 is peeled off. It is considered that the peeling phenomenon of the electrodeposited metal 10 appears because the tensile stress generated in the in-plane direction of the electrodeposited metal 50 during flexing becomes larger than the adhesion force of the electrodeposited metal 50 to the cathode 10. The reason why the electrodeposition metal 50 is peeled off from the upper side by flexing is considered to be because the electrodeposition metal 50 is connected so as to surround the lower side of the cathode 10 on the lower side of the electrodeposition metal 50, so that the adhesion is strong. . When the flexing pusher 82 is separated from the cathode 10, the curved deformation of the cathode 10 returns to the original flat state due to elastic deformation. The electrodeposited metal 50 that has been separated from the cathode 10 during flexing becomes flat like the cathode 10 and is in contact with the cathode 10 in parallel when the cathode 10 returns to its original flat state. . The flexing operation as described above is performed in the same manner alternately on both sides of the cathode 10.

  FIG. 3C is a view showing a conventional electrodeposition metal complete peeling step using a chiseling apparatus. The cathode after the flexing shown in FIG. 3B is transported to the front of the next chiseling device and temporarily stopped. In the chiseling device, as shown in FIG. 3C, a wedge-shaped chis blade 100 is inserted from the top to the bottom in a slight gap between the electrodeposited metal 50 and the cathode 10, and the electrodeposited metal 50 is It is completely stripped from the cathode 10.

JP-A-9-71891

  However, in the conventional electrodeposited metal peeling method described with reference to FIG. 3, if the gap between the electrodeposited metal 50 and the cathode 10 is narrow or the gap is bent, the chis blade 100 is moved to the electrodeposited metal 50. In other cases, the chis blade 100 is not inserted between the cathode 10 and the electrodeposited metal 50 and the electrodeposited metal 50 cannot be peeled off automatically. In such a case, there is a problem in that the number of processed sheets per unit time is reduced because it is necessary for an operator to manually peel off the chis blade.

  Accordingly, an object of the present invention is to provide an electrodeposited metal peeling apparatus that can automatically and reliably peel off.

In order to achieve the above object, an electrodeposited metal stripping apparatus according to an embodiment of the present invention is an electrodeposited metal stripping apparatus that strips the electrodeposited metal from a flat cathode on which the electrodeposited metal is adhered. And

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 4 is a configuration diagram showing an example of an electrodeposited metal peeling apparatus according to an embodiment of the present invention. In FIG. 4, the electrodeposited metal peeling apparatus according to the present embodiment includes a spacer insertion means 70 and a pressure peeling means 80. In FIG. 4, the cathode 10, the edge cover 20, the beam 30, the square hole 40, the electrodeposited metal 50, and the conveying means 60 are shown as related components of the electrodeposited metal peeling apparatus according to this embodiment. A transport rail 90 is shown. The spacer insertion means 70 is provided on both sides of the cathode 10 in parallel with the surface of the cathode 10. On the other hand, the pressure peeling means 80 is provided in a direction substantially perpendicular to the surface of the cathode 10.

  The cathode 10 is an electrode that acts as a cathode electrode in the electrodeposition process. The electrodeposited metal 50 is attached to the cathode 10 by immersing the cathode 10 and anode (not shown) in an electrolytic cell facing each other in an electrolytic solution containing metal ions such as copper, and applying a positive voltage to the anode and a negative voltage to the cathode. It is performed by applying voltage and performing electrolytic refining. Thereby, metal ions in the electrolytic solution adhere to the cathode 10 which is the negative electrode, and the electrodeposited metal 50 is formed. The electrodeposited metal 50 is a thin metal plate used as a product, and can be composed of various metal materials depending on the application. The cathode 10 may be made of various materials including metal as long as it is a conductor, but may be made of stainless steel, for example.

  The edge cover 20 is a member that covers the edge of the cathode 10. When the electrodeposited metal 50 adheres to the edge of the cathode 10, peeling becomes difficult, so the edge cover 20 is provided to cover the edge of the cathode 10.

  The beam 30 is a member that can be suspended from the upper part of the electrolytic cell when the cathode 10 is immersed in the electrolytic cell. The square hole 40 is a suspension hole used when the cathode 10 is suspended and conveyed. The electrolytic refining is performed in a state where the beam 30 is placed on the installed electrode and immersed in the electrolytic solution.

  The transfer means 60 is a means for moving the cathode 10 by moving on the transfer rail 90. In the electrodeposition metal peeling apparatus according to the present embodiment, a partial peeling process of the electrodeposited metal 50 is performed, and a part of the electrodeposited metal 50 is peeled from the cathode 10, and then the entire surface peeling process of the electrodeposited metal 50 is performed. . At that time, after partly peeling with the electrodeposition metal peeling apparatus shown in FIG. 2, the whole surface peeling step may be performed at the same place, but the whole surface is peeled off using the whole surface peeling apparatus at another place. You may make it perform a peeling process. In that case, the cathode 10 to which the electrodeposited metal 50 is adhered is transferred to the entire surface peeling apparatus by using the transfer means 60. Therefore, the conveying means 60 may be provided as necessary. 4 shows a rail-type transfer device that moves on the transfer rail 90 in FIG. 4, various transfer devices may be used as long as the cathode 10 can be transferred. When the transport means 60 is provided, the electrolytic refining is completed, and the cathode 10 to which the electrodeposited metal 50 is attached is placed on the transport means 60 and transported to the electrodeposition metal peeling apparatus according to this embodiment. It's okay.

  The pressure peeling means 80 is means for applying a pressing force to a portion near the center of the cathode 10 to which the electrodeposited metal 50 adheres to warp the cathode 10 and peel a part of the electrodeposited metal 50 from the cathode 10. The pressure peeling means 80 includes a main body 81 and a flexing pressing tool 82. The flexing pusher 82 is a means for pressing the central portion of the cathode 10 substantially perpendicularly to the cathode surface, and is provided to extend in the horizontal direction at a height near the center of the cathode 10. The flexing pusher 82 presses the vicinity of the center of the cathode 10 to warp the cathode 10 and peel the upper part of the electrodeposited metal 50. The electrodeposited metal 50 is a thin metal plate having a thickness of about several mm, for example, about 7 mm. When the cathode 10 is warped by applying a pressing force, the shear stress between the cathode and the electrodeposited metal is When the adhesive strength between the electrodeposited metals is exceeded, a part of the electrodeposited metal 50 peels from the cathode 10. Although the electrodeposited metal 50 is attached to the lower surface of the cathode 10 as a continuous film so as to straddle both surfaces, the electrode 10 does not have the electrodeposited metal 50 continuous on both surfaces, and is attached to one side. Therefore, the adhesion at the upper end is weaker than that at the lower end, and the electrodeposited metal 50 on the upper part of the cathode 10 begins to peel first. In addition, since it is preferable that peeling of the electrodeposited metal 50 occurs almost simultaneously on all the upper sides of the electrodeposited metal 50, the flexing pusher 82 has a shape extending in a horizontal direction in a columnar shape. , Provided parallel to the cathode surface 10.

  In this way, the pressure peeling means 80 applies a pressing force to the central portion of the cathode 10 substantially perpendicularly to the cathode surface to warp the cathode 10 and partially peel the electrodeposited metal 50, thereby electrodepositing the cathode 10. A gap is generated between the metal 50. The flexing pusher 82 moves in the horizontal direction perpendicular to the cathode surface. Moreover, the main body 81 has a drive means for moving the flexing pusher 82 horizontally, and may include a drive motor, for example.

  The spacer insertion means 70 inserts a spacer 72 into the generated gap when a part of the electrodeposited metal 50 is peeled off from the cathode 10 and a gap is formed between the electrodeposited metal 50 and the cathode 10, and pressure peeling is performed. Even when the means 80 stops pressing and the cathode 10 returns to the flat plate state, it is a gap maintaining means for maintaining the gap. The spacer insertion means 70 includes a spacer support part 71, a spacer 72, a rotation support part 73, and a control part 74.

  The spacer support portion 71 is means for supporting the spacer 72 in a rotatable manner. In the case where the electrodeposited metal peeling apparatus according to the present embodiment includes the transport unit 60, the spacer support portion 71 is configured integrally with the transport unit 60. The purpose of the spacer insertion means 70 is to maintain a gap at a location where the electrodeposited metal 50 is peeled off in the partial peeling step and to facilitate insertion of a separator or the like for full peeling in the next full peeling step. For this reason, when the entire surface of the electrodeposited metal 50 is peeled off after transportation, it is necessary to maintain a gap during transportation. In addition, when the electrodeposition metal peeling apparatus according to the present embodiment does not include the conveying means 60, it may be fixedly provided on both sides of the position where the cathode 10 is installed.

  The spacer 72 is inserted into the gap formed between the cathode 10 and the electrodeposited metal 50 by the pressure peeling means 80, and the gap exists even when the pressure peeling means 80 stops pressing and the cathode 10 returns to the flat plate state. It is the insertion means for maintaining. The spacer 72 is rotatably supported by the spacer support means 71. The spacers 72 are arranged on both sides of the cathode 10 in parallel to the cathode surface so that they can be quickly inserted when a gap is generated between the cathode 10 and the electrodeposited metal 50. The spacer 72 is preferably made of an elastic material such as ABS resin so that the insertion position can be followed even when the anode 10 moves back and forth by flexing on the opposite surface side, and the shape is a thin plate. Is desirable.

  The rotation support portion 73 is a portion that becomes a center of rotation when the spacer 72 rotates, and supports the spacer 72 rotatably. The spacer 72 rotates from both sides to the inside where the cathode 10 is located around the rotation support portion 73 and is inserted into a gap formed between the cathode 10 and the electrodeposited metal 50. The height of the rotation support portion 73 determines the position where the spacer 72 is in a horizontal state. However, since the spacer 72 is inserted from above the cathode 10, the rotation support portion 73 is installed at a height near the upper portion of the cathode 10. It is preferable. Further, it is desirable that the rotation support portion 73 is made of an elastic body such as ABS resin so that the spacer 72 can easily follow the anode 10 during flexing.

  The control unit 74 is control drive means for driving the spacer 72 to rotate. In conjunction with the pressing operation of the flexing pressing tool 82 of the press peeling means 80, the spacer 72 rotates and falls at the timing when the electrodeposited metal 50 is partially peeled from the cathode 10, and in the gap between the cathode 10 and the electrodeposited metal 50. Drive control for rotating the spacer 72 at the insertion timing is performed. Then, after the insertion, an operation of stopping and maintaining the spacer 72 at a predetermined height or rotation angle is performed. The control unit 74 may be realized by a predetermined electronic circuit, a microprocessor that operates according to a program, or the like.

  It is preferable that the spacer support portion 71, the spacer 72, and the rotation support portion 73 of the spacer inserting means 70 are provided in parallel with the cathode surface with the same surface as the cathode surface or with a slight gap. As a result, the position where the gap where the electrodeposited metal 50 peels from the cathode 10 and the rotation surface of the spacer 72 coincide with each other, and the spacer 72 can be easily inserted into the gap without greatly curving the cathode 10. It becomes.

  In the present embodiment, the rotary spacer insertion means 70 has been described. However, if the spacer 72 can be inserted when the electrodeposited metal 50 is peeled off from the cathode 10 and a gap is generated, the spacer insertion means 70 can be inserted. Can have various configurations. For example, the spacer 72 may be configured as a slide-type spacer insertion unit 70 in which the spacer 72 is slid in the horizontal direction or obliquely downward and inserted into the gap.

  Next, the operation of the electrodeposited metal peeling apparatus according to this embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is a diagram for explaining an example of a partial peeling process of the electrodeposited metal peeling apparatus according to the present embodiment.

  FIG. 5A is a view showing a state in which the cathode 10 on which the electrodeposited metal 50 is formed is installed in the electrodeposited metal peeling apparatus according to the present embodiment. In FIG. 5A, the upper diagram is a side view and the lower diagram is a front view. Hereinafter, this point is the same in FIGS. 5 and 6.

  In FIG. 5A, the cathode 10 on which the electrodeposited metal 50 is formed is installed in the electrodeposited metal peeling apparatus according to the present embodiment, and the flexing pressing tool 82 of the pressure peeling means 80 is arranged in the front. It becomes a state. Further, the spacer 72 stands by in a state of extending straight upward on both sides of the cathode 10.

  In FIG. 5A, the electrodeposited metal 50 is formed only on one side of the cathode 10 and the flexing pusher 82 is also arranged only on one side of the cathode 10, but this is easy to understand. Therefore, only one side has been described as an example. When the electrodeposited metal 50 is formed on both surfaces of the cathode 10, the pressure peeling device 80 may be provided symmetrically on both surfaces of the cathode 10 to peel the electrodeposited metal 50 on both surfaces. In this case, partial peeling of the electrodeposited metal 50 may be performed on each side.

  FIG. 5B is a view showing a state where the electrodeposited metal 50 is partially peeled from the cathode 10 by the pressing operation of the pressure peeling means 80. 5B, the flexible pusher 82 is pushed into the cathode 10, and the cathode 10 is warped. As a result, stress is generated in the direction in which the electrodeposited metal 50 is peeled off, and the upper portion of the electrodeposited metal 50 is partially peeled from the cathode 10. In the stage of FIG. 5B, the spacer 72 of the spacer insertion means 70 is in a state of extending vertically upward.

  FIG. 5C is a view showing a state in which the spacer 72 is inserted into the gap formed between the cathode 10 and the electrodeposited metal 50.

As shown in the lower part of FIG. 5C, the spacer 72 rotates inward about the rotation support portion 73 and is inserted into the gap between the spacer 10 and the electrodeposited metal 50. The spacer 72 is rotated 90 ° by the drive control of the control means 74 fixedly installed in the vicinity of the flexing device.

  FIG. 5D is a diagram showing a state in which the flexing pressing tool 82 of the pressing / separating means 80 stops the pressing operation by applying the pressure and returns to the original state. Thereby, the cathode 10 returns from the curved state to the flat plate state. As shown in FIG. 5D, the flexure pusher 72 returns to its original position while the spacer 72 remains rotated by 90 °, and the spacer 72 is sandwiched between the electrodeposited metal 50 and the cathode 10. become. That is, when the cathode 10 returns to the flat plate state, the electrodeposited metal 50 tries to return to the flat plate state in contact with the cathode 10, but the spacer 72 is inserted between the electrodeposited metal 50 and the spacer 10. The existence of a gap between the cathode 10 and the electrodeposited metal 50 is maintained. In this state, the cathode with the electrodeposited metal 50 is transported together with the spacer insertion means 70 fixed to the transport means 60 to the chiseling position where the entire surface is peeled off. Maintain the gap.

  FIG. 6 is a diagram showing an example of the entire surface peeling process of the electrodeposited metal peeling apparatus according to the present embodiment. FIG. 6A is a view showing a state in which the blade-shaped separation member is inserted into the gap between the electrodeposited metal 50 and the spacer 10. Although various members may be used as the blade-shaped separation member, for example, a chis blade 100 may be used. As shown in FIG. 6A, the chis blade 100 is inserted by being lowered from above toward the gap maintained by the spacer 72. Since the space into which the chis blade 100 is inserted is formed by the spacer 72, the chis blade 100 can be easily inserted between the electrodeposited metal 50 and the spacer 10.

  FIG. 6B is a view showing a state where the chis blade 100 is inserted below the spacer 72. The chis blade 100 descends as it is, and strips the electrodeposited metal 50 from the cathode 10. As shown in the lower figure of FIG. 6B, the spacers 72 are provided at both ends of the cathode surface that do not come into contact with the chis blade 100 passing through the center of the cathode surface. The electrodeposition metal 50 can be smoothly peeled off without interference.

  FIG. 6C is a view showing a state in which the electrodeposited metal 50 is peeled from the cathode 10 on the entire surface. As shown in FIG. 6C, when the chis blade 100 reaches near the lower part of the cathode 10, the electrodeposited metal 50 is completely peeled off from the cathode 10 and peeled off. Thus, the chis blade 100 can reliably peel the electrodeposited metal 50 from the cathode 10.

  FIG. 6D is a view showing a state in which the chis blade 100 is returned upward. As shown in FIG. 6D, when the electrodeposited metal 50 is completely peeled off from the cathode 10, the chis blade 100 returns to its original state and is set upward again. Further, in the state of FIG. 6D, the spacer 72 is rotated 90 ° by the drive control of the control means 74 fixedly installed in the vicinity of the chiseling device, and returns to the original set state.

  Although not shown, the spacer support means 71 that supports the spacer 72 fixed to the transport means 60 may be configured to be a folding type in which a spring is housed in the indirect portion. By configuring in this way, a narrow space can pass through without interfering with the wall when being transported in a state where the cathode 10 is not placed on the transport means 60.

  As described above, in the state where the cathode 10 is bent by the flexing pusher 82 and the upper side of the electrodeposited metal 50 is separated from the cathode 10, the electrodeposited metal peeling apparatus according to this embodiment is used. The spacer 72 can be inserted into a gap that can be temporarily formed between the peeled portion 50 and the cathode 10, and can be conveyed to the next process position with the spacer 72 inserted in the gap. Further, in the chiseling for complete peeling in the next process, the gap between the electrodeposited metal 50 and the cathode 10 is appropriately opened by the spacer 72, so that the chis blade 100 is automatically inserted between the electrodeposited metal 50 and the cathode 10. become able to.

  In FIGS. 5 and 6, an example in which the spacer inserting means 70 is provided in the conveying means 60 has been described.
