Description

  The present invention relates to an electrodeposited metal stripping apparatus that strips an electrodeposited metal electrodeposited on the surface of a cathode having a flat plate shape, and an electrodeposited metal separation apparatus using the same.

  Conventionally, electrolytic refining of metals such as copper is performed by energizing a cathode and anode alternately arranged in an electrolytic cell filled with an electrolytic solution, and electrodepositing metal on both sides of the cathode. As the cathode, a stainless steel thin plate or the like is generally used as a permanent cathode that can be repeatedly used, 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 the rectangular holes 40 are hung and conveyed by hooking a hook of the conveying device of the cathode 10. 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 the transfer device 70 used in the conventional electrodeposition metal peeling method. In FIG. 2, the cathode 10 is placed on a transport device 70, both surfaces of the beam 30 are supported by a transport guide 35, and the lower portions of the edge covers 20 on both side portions are fixed by a U-shaped fixture 60. .

  In operation, as shown in FIG. 1, the cathode 10 is placed in a vertical direction with a beam 30 for suspending it in the electrolytic cell, and the cathode 10 It is conveyed in parallel and stops once in front of the in-line flexing device.

  3A to 3B are views showing a conventional electrodeposition metal peeling process using a flexing apparatus. FIG. 3A is a diagram illustrating 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 81 and a receiving metal fitting 90 are provided on both surfaces of the cathode 10 on which the electrodeposited metal 50 is formed. The flexing pressing tool 81 is provided at a substantially central portion of the surface of the cathode 10 and has, for example, a cylindrical shape having a diameter of 50 mm and a horizontal length of 500 mm. The metal fitting 90 is provided on the upper side of the electrodeposited metal 50 and has, for example, a cylindrical shape with a diameter of 50 mm and a horizontal length of 1200 mm.

  FIG. 3B is a diagram showing an electrodeposited metal partial peeling process using the flexing pressing tool 81. As shown in FIG. 3B, the vicinity of the center of the cathode 10 is pushed by about 50 mm by the flexing pusher 81. 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. When the upper side of the electrodeposited metal 50 is peeled off, the metal fitting 90 plays a role of preventing the electrodeposited metal 50 from peeling off from the anode 10 and falling over. 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 81 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 small gap between the electrodeposited metal 50 and the cathode 10, and the electrodeposited metal 50 is completely covered with the cathode. 10 is peeled off.

  Also, before the step of inserting and peeling the chisel between the electrodeposited metal and the cathode plate, the electrodeposited metal stripping is provided with a brazing step of opening the upper side of the electrodeposited metal and bending it outward. A lower guide for holding the lower side of the cathode plate from both sides, and an upper guide disposed near the surface of the electrodeposited metal on the upper side of the cathode plate to be brazed; A pressing member that presses the vicinity of the center of the cathode plate from the left and right, and a brazing member that secures a gap for facilitating the insertion of the chisel by bending the upper side of the opened electrodeposited metal. An invention performed by a brazing device has been proposed (see, for example, Patent Document 1).

JP 2008-231501 A

  However, in the conventional electrodeposition metal peeling method described with reference to FIGS. 1 to 3, since the gap between the electrodeposition metal and the cathode is sometimes narrow or bent, the chis blade is caught on the upper end surface of the electrodeposition metal. In some cases, the electrodeposited metal cannot be automatically removed. In such a case, manual stripping work by an operator is required, which is one of the factors for reducing the number of processed sheets per unit time.

  Moreover, in the electrodeposition metal stripping method and the brazing apparatus described in Patent Document 1, since the brazing member uses a brazing member having a wedge shape with a substantially right-angled cross section, the bending angle of the electrodeposited metal is adjusted. In order to change the bending angle, the brazing member has to be replaced, and there is a problem that it is difficult to cope with various electrodeposition metal stripping.

  Therefore, according to the present invention, since the gap between the electrodeposited metal and the cathode is small and bent even after the flexing is performed, the electrodeposited metal cannot be automatically peeled off from the cathode in the next step chiseling. An electrodeposition metal peeling apparatus capable of peeling off various electrodeposited metals, which can be peeled off almost automatically and almost flexibly according to the type of electrodeposited metal and cathode, and It aims at providing the used electrodeposition metal separation apparatus.

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

  FIG. 4 is a side configuration diagram showing an example of an electrodeposited metal peeling apparatus according to Embodiment 1 of the present invention. In addition, since the electrodeposition metal peeling apparatus demonstrated in FIG. 1, FIG. 2, FIG. 3A-FIG. 3C has shown the structure of the general electrodeposition metal peeling apparatus, about a common component also in a present Example. Shall be given the same reference number.

  In FIG. 4, the electrodeposited metal peeling apparatus according to the first embodiment includes a cathode 10, a beam 30, a transport guide 35, a fixture 60, a transport apparatus 70, a flexing apparatus 80, and a metal fitting 90. Electrodeposition metal deformation machine 100, controller 130, support 110, cross beam 120, and controller 130 are provided. Moreover, the electrodeposition metal 50 used as peeling object is formed on the surface of the cathode 10 as a related component.

  In the electrodeposition metal apparatus according to the present embodiment, the fixture 60 is provided on the transport device 70, the cathode 10 is installed on the fixture 60, and the fixture 60 supports the lower part of the cathode 10. A beam 30 is provided on the top of the cathode 10 to support the cathode 10 from above. Conveying guides 35 are provided on both sides of the beam 30, and serve as guides that determine the direction in which the conveying device 70 conveys the cathode 10. Two struts 110 are provided on both sides perpendicular to the surface of the cathode 10 so as to sandwich the cathode 10 from both sides. Moreover, the cross beam 120 is provided so that the upper end part of the two support | pillars 110 may be connected. A flexible pressing tool 81, a receiving tool 90, and an electrodeposition metal deforming machine 100 are provided on both inner sides of the support 110 so as to sandwich the cathode 10, respectively. Further, a conveyance guide 35 is supported on the horizontal beam 120. Furthermore, a controller 130 is connected to the electrodeposition metal deformation machine 100.

  The cathode 10 is an electrode that becomes a cathode in the electrodeposition process, and is a metal to which the electrodeposited metal 50 is attached. As described above, the cathode 10 may be a stainless steel thin plate or the like as a permanent cathode that can be used repeatedly. The electrodeposition process is generally performed by electrodeposition on both sides of the cathode 10 by placing a cathode 10 and an anode in an electrolytic cell filled with an electrolyte such as a metal so that a current flows between the cathode 10 and the anode. Metal 50 is formed. The cathode 10 on which the metal such as copper is electrodeposited on both sides by the electrodeposition process is carried into the electrodeposition metal peeling apparatus according to the present embodiment through a necessary process such as cleaning.

  The beam 30 is a member that supports the cathode 10 from above. Further, the transport guide 35 supports the beam 30 from both sides, and guides the transport direction when the transport device 70 transports the cathode 10.

  The fixture 60 is means for supporting the lower portion of the cathode 10 and fixing and supporting the cathode 10 in an upright state. For example, as shown in FIG. 2, the fixture 60 may be formed in a U shape and may be configured to fix the cathode 10 with both sides sandwiched from both sides, or may be configured in another shape or structure. Also good. Various means can be used for the fixture 60 as long as the cathode 10 can be fixedly supported in a state in which the cathode 10 stands substantially vertically.

  The transport device 70 is means for transporting the cathode 10. The conveyance device 70 may be configured to perform both the carry-in to the electrodeposition metal peeling apparatus according to the present embodiment and the carry-out from the electrodeposition metal peeling apparatus according to the present embodiment. As described above, the cathode 10 is carried into the electrodeposition apparatus according to the present embodiment on the cathode 10 in which the electrodeposited metal 50 is formed on both surfaces through the electrodeposition process. That is, the conveyance device 70 conveys the cathode 10 from the electrolytic cell to the electrodeposition apparatus according to the present embodiment.

  On the other hand, in the electrodeposition metal peeling apparatus according to the present embodiment, the electrodeposition metal partial peeling process is performed, and the electrodeposition metal 50 is partially peeled. Therefore, after the electrodeposition metal partial peeling step, it is necessary to perform an electrodeposition metal complete peeling step for completely peeling the electrodeposited metal 50 from the cathode 10. Since the electrodeposition metal complete peeling step is generally performed by a separation device called a chiseling device, the conveying means 70 partially peels the electrodeposited metal 50 by the electrodeposition metal peeling device according to this example. After that, the cathode 10 is conveyed to the chiseling device. In the chiseling device, the electrodeposited metal 50 is separated from the cathode 10 using a chis blade 150. Accordingly, the transport device 70 transports the cathode 10 between the devices that perform the respective steps.

  The transport device 70 may have various configurations as long as the cathode 10 can be transported. For example, the transport device 70 may include a transport rail so that the cathode 10 moves on the transport rail.

  The flexing device 80 presses the central region on the surface of the cathode 10 on which the electrodeposited metal 50 is formed in the lateral direction (horizontal direction), warps the cathode 10, and the upper end of the electrodeposited metal 50 from above the cathode 10. It is a pressure peeling means for peeling. The flexing device 80 includes a flexing pressing tool 81, a cylinder 82, and a drive unit 83. The flexing pressing tool 81 is a means for pressing the central portion of the cathode 10 substantially perpendicularly to the cathode surface, and is provided at a height near the center of the cathode 10 and extending in the horizontal direction perpendicular to the paper surface. It has a cylindrical shape. The flexing pusher 81 presses the central region of the cathode 10 to warp the cathode 10 and peel the upper portion 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 at the same time on all the upper sides of the electrodeposited metal 50, the flexing pusher 81 has a shape extending in a horizontal direction in a columnar shape. , Provided parallel to the cathode surface 10.

  In this way, the flexing device 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 81 performs an operation of moving in the horizontal direction perpendicular to the cathode surface by the expansion and contraction movement of the cylinder 82. The cylinder 82 is driven by the drive unit 83. For example, the drive unit 83 accommodates a motor, and is configured so that the cylinder 82 can be driven in a horizontal direction perpendicular to the cathode surface. The drive unit 83 may be configured to be connected to the controller 130 and to control the drive timing of the flexing pusher 81, for example.

  The metal fitting 90 is a means for preventing the electrodeposition metal 50 from being overly peeled and peeled off from the anode 10 when the upper side of the electrodeposition metal 50 is peeled off, and toppling over. The support fitting 90 is supported by the support 110 via the support member 91. The metal fitting 90 is provided at a position close to the electrodeposited metal 50 and facing the upper portion of the electrodeposited metal 50 in order to prevent the electrodeposited metal 50 partially peeled off from falling off and falling. In addition, like the flexure pressing tool 81, the receiving bracket 90 preferably has a columnar shape extending in a direction perpendicular to the paper surface.

  The electrodeposition metal deforming machine 100 bends and deforms the upper end portion of the electrodeposited metal 50 partially peeled from the cathode 10 by the pressing of the cathode 10 by the flexing device 80, and between the cathode 10 and the electrodeposited metal 50. This is an electrodeposited metal deformation means for forming a gap. The electrodeposited metal deformation machine 100 includes a rotating member 101, a rotating shaft 102, and a support member 103. In addition, the electrodeposited metal deforming machine 100 is connected to a controller 130 so that the rotational driving of the rotating member 101 is controlled.

  The rotating member 101 comes into contact with the upper part of the electrodeposited metal 50 partially peeled while rotating, and gives the electrodeposited metal 50 a lateral (horizontal) force in a direction away from the cathode 10, so that the electrodeposited metal 50 is placed outside. It is a means which is plastically deformed so as to open. Therefore, the rotating member 101 is arranged at a position where the lower surface comes into contact with the upper portion of the electrodeposited metal 50 when the flexing pusher 81 presses and warps the cathode 10 and the upper portion of the electrodeposited metal 50 is peeled off. The Further, the rotating member 101 rotates in such a direction that the upper end portion of the electrodeposited metal 50 is disengaged away from the cathode 10 so as to give the electrodepositing metal 50 an opening force. That is, in FIG. 4, the right rotating member 101 rotates counterclockwise, and the left rotating member 101 rotates clockwise.

  The rotating member 101 is preferably supported rotatably on the rotating shaft 102 in an eccentric state. Since it is eccentrically supported by the rotating shaft 102, the rotation stroke of the rotating member 101 can be increased, and therefore, a force for efficiently opening the electrodeposited metal 50 to the outside can be applied.

  The rotating member 101 preferably has a column shape extending in parallel to the cathode 10 with a cross-sectional shape of a plane perpendicular to the rotating shaft 102 being a horizontally long shape. By having a horizontally long shape, the rotational stroke of the rotating member 101 can be increased when attached to the rotating shaft 102 in an eccentric state, and the lateral opening force caused by the rotation of the rotating member 101 can be efficiently electrodeposited. It can be applied to the metal 50. Further, by making the cross-sectional shape of the surface perpendicular to the rotation shaft 102 of the rotating member 101 into a horizontally long shape, the gap between the electrodeposited metal 50 and the cathode 10 after the rotating member 101 contacts the upper end of the electrodeposited metal 50. It is possible to increase the contact area between the rotating member 10 and the electrodeposited metal 50 when the electrodeposited metal 50 is given an opening force. Thereby, the force of the direction which expands the clearance gap between the electrodeposition metal 50 and the cathode 10 can be provided to the electrodeposition metal 50 efficiently. In FIG. 4, the rotating member 101 has an elliptical cross-sectional shape in a plane perpendicular to the rotating shaft 102, has an elliptical column shape extending parallel to the cathode surface, and is eccentric to the rotating shaft 102. Supported by the state. As a result, the electrodeposited metal 50 can be softly contacted, and the rotating member 101 can easily enter the gap between the electrodeposited metal 50 and the cathode 10, and the electrodeposited metal 50 can be reliably bent and deformed outward.

  Various rotation angles of the rotating member 101 may be set according to the required opening angle of the electrodeposited metal 50. That is, in order to open the electrodeposited metal 50 widely, the rotating member 101 may be rotated once or at a relatively large predetermined angle of less than one rotation. On the other hand, when it is desired to reduce the opening angle of the electrodeposited metal 50, the electrodeposited metal 50 may be rotated at a relatively small predetermined angle that is less than one rotation. Accordingly, the rotation angle can be set according to the types of the cathode 10 and the electrodeposited metal 50 without replacing the rotating member 101, and the electrodeposited metal 50 can be bent and deformed at a desired opening angle. it can. Note that the setting and control of the rotation angle of the rotating member 101 may be performed by the controller 130.

  The supporting member 103 is a member for rotatably supporting the rotating member 101, and a rotating shaft 102 is provided at the tip. Further, the support member 103 may have various configurations as long as the rotation member 101 can be rotatably supported. For example, as illustrated in FIG. 4, the support member 103 may be configured to be supported by a support column 110.

  The support member 103 may be configured as an extendable cylinder. Thereby, the distance between the rotating member 101 and the cathode 10 can be adjusted, and more appropriate bending deformation of the electrodeposited metal 50 can be performed together with the control of the rotation angle of the rotating member 101. In the case where the support member 103 is configured as a cylinder, a driving source such as a motor may be built in like the flexing device 80 and the cylinder may be driven to expand and contract. The expansion / contraction distance may be performed by the controller 130.

  As described above, the electrodeposition metal apparatus according to the present embodiment has the rotating member 101 so that the chis blade can be inserted at the optimum position between the electrodeposition metal 50 and the cathode 10 in the next electrodeposition metal complete peeling step. If necessary, an adjustment mechanism that can freely adjust the distance and angle of the upper end of the electrodeposited metal 50 is provided, so that it is possible to cope with changes in the size and position of the electrodeposited metal 50. .

  The support column 101 is a means for fixing and supporting the flexing device 80, the receiving metal fitting 90, the electrodeposited metal deforming machine 100, and the cross beam 120, and is provided so as to sandwich both sides of the cathode 10. The flexing device 80, the metal fitting 90, and the electrodeposited metal deforming machine 100 may be fixedly supported by various means. For example, a support column 101 as shown in FIG. 4 is provided and fixedly supported thereto. May be.

  The cross beam 120 is a means for fixing and supporting the conveyance guide 35. The lateral beam 120 is configured to be supported by the support 110.

  The controller 130 is a means for controlling the rotation angle of the rotating member 101 of the electrodeposition metal deformation machine 100. The control of the rotation angle may be performed by the driver according to conditions, or the controller 130 automatically performs setting control based on conditions such as the type and size of the cathode 10 and the electrodeposited metal 50. It is good also as a structure to perform. The controller 130 may be configured as a microcomputer including a predetermined electronic circuit and a CPU (Central Processing Unit) that operates according to a program. Further, as described above, when the support member 103 of the electrodeposition metal deformation machine 100 is configured as a cylinder, the controller 130 may be configured to control the support member 103 together, or the flexing The pressing timing of the device 80 may also be controlled.

  Next, an operation example of the metal electrodeposition peeling apparatus according to the first embodiment will be described with reference to FIGS. 5A to 5E. 5A to 5E are diagrams showing a series of operations in the electrodeposition metal partial peeling step by the electrodeposition metal peeling apparatus according to the present embodiment. 5A to 5E, the same components as those described so far are denoted by the same reference numerals, and the description thereof is omitted. Further, in FIGS. 5A to 5E, only components necessary for explaining the operation are shown.

  FIG. 5A is a diagram illustrating a state in which the cathode 10 with the electrodeposited metal 50 attached on the surface is carried into the metal electrodeposition peeling apparatus according to the first embodiment. The electrodeposited metal peeling apparatus according to the present embodiment is installed in the vicinity of the flexing apparatus 80. The rotating member 101 having an elliptical column is horizontally disposed on the outer side of the upper end of the electrodeposited metal 50 peeled from the cathode 10 by flexing. To place. The length of the elliptical column rotating member 101 is slightly longer than the width of the electrodeposited metal 50 and rotates in one direction with an eccentric rotating shaft 102. Further, on the same side as the rotating member 101, a receiving jig 90 is disposed on the upper part facing the electrodeposited metal 50.

  FIG. 5B is a diagram illustrating a state where partial peeling of the electrodeposited metal 50 from the cathode 10 has occurred due to the pressing drive of the flexing device 80. In FIG. 5B, the flexing device 80 is activated and the flexing pusher 81 presses the central region of the cathode 10. As a result, the cathode 10 warps and a part of the upper portion of the electrodeposited metal 50 is peeled off from the cathode 10. The partially peeled electrodeposited metal 50 is in contact with the receiving jig 90, and peeling is suppressed. When the electrodeposited metal 50 comes into contact with the receiving jig 90, the positions of the rotating member 101 and the electrodeposited metal 50 approach each other, and the rotating member 101 is positioned above the electrodeposited metal 50. Here, the rotating member 101 of the electrodeposited metal deformation machine 100 starts to rotate.

  FIG. 5C is a diagram illustrating a state in which the rotating member 101 of the electrodeposited metal deforming machine 100 rotates and contacts the upper end portion of the electrodeposited metal 50. Here, the rotating member 101 rotates in such a direction that the lower surface contacting the upper end portion of the electrodeposited metal 50 pays out the electrodeposited metal 50 from the cathode 10 side to the outside.

  FIG. 5D is a view showing a state where the electrodeposited metal 50 is pushed and bent. In FIG. 5D, the rotating member 101 enters the gap between the electrodeposited metal 50 and the cathode 10 and applies a force in a direction away from the cathode 10 to the electrodeposited metal 50. As a result, the upper end portion of the electrodeposited metal 50 is pushed and bent to the side opposite to the cathode 10 and is plastically deformed. The receiving jig 90 receives the electrodeposited metal 50 and serves as a fulcrum for bending deformation of the electrodeposited metal 50.

  Thus, as shown in FIGS. 5B to 5D, in the state in which the flexing pusher 81 is most pushed, the tip of the rotating member 101 of the elliptical column that rotates eccentrically is electrodeposited that has been peeled off from the cathode 10 by flexing. Since the upper end of the metal 50 is pushed and bent while rotating from the cathode 10 side to the opposite side to the cathode 10, the upper end of the electrodeposited metal 50 is plastically deformed to the opposite side to the cathode 10. At this time, the side without the cathode 10 at the upper end of the electrodeposited metal 50 is pressed against the metal fitting 90. That is, the metal fitting 90 installed on the side opposite to the cathode 10 at the upper end of the electrodeposited metal 50 serves to determine the bending position of the upper end of the electrodeposited metal 50 in order to limit the bending range of the upper end of the electrodeposited metal 50. Fulfill.

  FIG. 5E is a view showing a state where the electrodeposited metal partial peeling step is completed. In FIG. 5E, the flexing pusher 81 returns to the original state, and the pressing of the cathode 10 is finished. At this time, the electrodeposited metal 50 returns to the state on the surface of the cathode 10, but the upper end portion of the electrodeposited metal 50 is bent and deformed so as to open outward from the cathode 10 side. The gap between the metal 50 is secured. In the actual example, in FIG. 5E, even when the flexing pusher 81 is pulled, a gap of about 3 mm is left between the plastically deformed upper end of the electrodeposited metal 50 and the cathode 10. The mounting position of the elliptical column of the rotating member 101 was adjusted in advance.

  After the electrodeposition metal partial peeling step of FIG. 5E, the cathode 10 on which the electrodeposited metal 50 is formed is transferred to the chiseling device by the transfer device 70, and the electrodeposition metal complete peeling step is performed. In the chiseling device, the chis blade 150 is inserted between the cathode 10 and the electrodeposited metal 50, and the inserted chis blade 150 is lowered to the lower part of the cathode 10 to completely peel the electrodeposited metal 50 from the cathode 10. ,To separate. At this time, since the upper end portion of the electrodeposited metal 50 is opened outward and a gap with the cathode 10 is formed by the electrodeposition metal peeling apparatus according to the present embodiment, the chis blade 150 can be easily electrodeposited with the cathode 10.

  When using a conventional electrodeposition metal stripping device, the chis blade in chiseling cannot be inserted between the electrodeposited metal and the cathode, and manual stripping work by the worker is 5 sheets in total on both sides per 1000 processed cathodes. Although it occurred frequently, by introducing the electrodeposited metal peeling apparatus according to Example 1, the total number of both sides per 1000 processed cathodes was reduced to about 1.

  The electrodeposited metal separating apparatus according to the present embodiment including the conveying device 70 and the chiseling apparatus constitute an electrodeposited metal separating apparatus. The electrodeposited metal separator can automatically separate the electrodeposited metal 50 from the cathode 10.

  FIG. 6 is a configuration diagram illustrating an example of a rotating member of the electrodeposited metal peeling apparatus according to the second embodiment. In the electrodeposition metal peeling apparatus according to the second embodiment, only the configuration of the rotating member 104 is different from the electrodeposition metal apparatus according to the first embodiment, and other components are the same as those of the electrodeposition metal peeling apparatus according to the first embodiment. Since the configuration of FIG. 4 can be applied as it is, the entire configuration is not shown. In addition, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The electrodeposited metal peeling apparatus according to the second embodiment is also installed in the vicinity of the flexing apparatus 80. However, in the electrodeposited metal peeling apparatus according to the second embodiment, the upper end of the electrodeposited metal 50 peeled from the cathode 10 by flexing. A plurality of short elliptical column rotating members 104 laid out on the outside are arranged in the horizontal direction. Moreover, as shown in FIG. 6, a small roller 105 is disposed on the outer periphery of the rotating member 104 of each short elliptical column. The total length of a plurality of such short elliptical rotating members 104 is slightly longer than the width of the electrodeposited metal 50 and rotates in one direction with an eccentric rotating shaft 102.

  In this way, a plurality of rotating members 104 made of elliptical columns having a short horizontal length are provided, and a small roller 105 is provided at the tip of the rotating member that contacts the electrodeposition member 50 so that the electrodeposited metal 50 is bent and deformed. May be. Since the small roller 105 is provided at the tip, it is possible to reliably prevent the upper end of the electrodeposited metal 50 from being damaged when contacting the upper end of the electrodeposited metal 50.

  In addition, the electrodeposition metal peeling apparatus which concerns on Example 2 also carries out the operation | movement demonstrated in FIG. 5A-FIG. 5E of Example 1, and bends and deforms the electrodeposition metal 50, The cathode 10 and the electrodeposition metal 50 are the same. A gap between them can be secured.

  Actually, when the electrodeposition metal peeling apparatus according to Example 2 was prototyped and carried out, in the conventional electrodeposition metal peeling apparatus, the chis blade in chiseling cannot be inserted between the electrodeposition metal and the cathode, and the manual operation by the worker is not possible. The stripping operation occurred at a frequency of about 5 on both sides of 1000 processed cathodes. However, by introducing the electrodeposition metal peeling apparatus according to Example 2, both sides were aligned on 1000 processed cathodes. Reduced to about 1 sheet.

  Further, the surface on the cathode 10 side at the upper end of the electrodeposited metal 50 that contacts the rotating member 104 of the elliptical column of the electrodeposited metal peeling apparatus has a small roller 105 attached to the outer peripheral portion of the rotating member 104. There were no scratches due to friction, and the electrodeposited metal 50 was as smooth as the other surface on the cathode 10 side.

  Thus, according to the electrodeposition metal peeling apparatus which concerns on Example 2, productivity can be improved by automation, preventing reliably that the upper end part of the electrodeposition metal 50 generate | occur | produces.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.
