Description

  More particularly, the present invention relates to a method and system for sorting out defective cathode plates, and more particularly, to a poorly electrodeposited cathode plate and a deformation of the cathode plate, which have been poorly electrodeposited due to the formation of bumps or insufficient electrodeposition in electrolytic refining of metals. More particularly, the present invention relates to a method for sorting out and rejecting defective cathode plates that are defective due to an abnormality of a protector and a system thereof.

  Electrolytic purification of metal using permanent cathode (PC) by ISA method, for example, electrolytic purification of copper is performed by using a large number of stainless steel cathode plates (permanent cathode plates) and crude copper in an electrolytic cell in which an electrolytic solution is stored. It is carried out by electrodepositing electrolytic copper on both surfaces of the cathode plate by alternately immersing the cast anode plate (anode plate) and energizing it. Then, the electrolytic copper 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 has been widely adopted in recent years because it is strong and can be used repeatedly, and because it has good flatness, it does not easily cause a short circuit during electrolytic purification. Then, electrolytic copper 2 is electrodeposited on both surfaces of the cathode plate 1 after the electrolytic purification, and the electrolytic copper 2 stripped by the stripping device is transported by the transport device as a set of two sheets to ensure flatness. For this purpose, a flat press for corrugation and corrugation for corrugation that corrugates electrolytic copper are performed, and the product is provided as a product.

  For example, JP-A-2005-240146 (Patent Document 1) is known as a conventional electrolytic copper plate recovery system. This electrolytic copper plate recovery system includes a plywood carry-in portion into which a plywood with a SUS plate (cathode plate) having electrolytic copper deposited on the surface thereof, a cleaning device for cleaning these plywood, and a SUS plate A stripping device for stripping the electrical copper plate from the SUS, a SUS unloading unit for collecting the SUS plate after stripping, a defective product extracting unit for extracting defective products that failed to be peeled off during the stripping process, and after stripping A joining device for joining the electrolytic copper plates, a loading device for loading and holding the joined electrolytic copper plates, a packaging device for packing the laminated electrolytic copper plates, and a copper plate unloading unit for collecting the electrolytic copper plates after packing In addition, a conveyor is provided between each device or the loading / unloading unit.

  An outline of the operation of the above-described electrolytic copper plate recovery system will be described. First, the plywood carried into the plywood carry-in section is transported to the cleaning device in a suspended state and cleaned. The cleaned plywood is transported to the traverse conveyor by the transport conveyor, and peeled continuously one by one in a state where the transport direction of the plywood is deflected in a direction parallel to the plywood surface (that is, the axial direction of the crossbar 4) by the traverse conveyor. It is conveyed to the picking device. When the stripping device receives the plywood one by one, the electrolytic copper plate is peeled off from the SUS plate, and the SUS plate and the electrolytic copper plate are each conveyed by a conveyor. The conveyed electrical copper plate is packed by a packing device and collected from the copper plate carry-out section.

  However, when stripping electrical copper from a poorly electrodeposited cathode plate, which has been poorly electrodeposited due to the occurrence of bumps or insufficient electrodeposition, using a stripping device, not only does the stripping work well, but there is a problem with the stripping device. May occur. Once trouble occurs, the traverse conveyor must be stopped to deal with it, which not only takes time, but also leads to a reduction in the work efficiency of the entire electric copper plate recovery system, resulting in a significant reduction in productivity. Also, the stripped electrical copper plate is not a product.

  Moreover, in the electrolytic refining by the permanent cathode method, the cathode plate from which the electrolytic copper plate has been peeled off is reused, but the cathode plate is deformed, or the shape is considered defective due to abnormalities such as breakage or peeling of the protector. Since the cathode plate cannot be reused as it is, it is necessary to distinguish it from a normal cathode plate.

  Therefore, the present invention strips the electrodeposited metal from the electrodeposited cathode plate, which has been electrodeposited poorly due to the formation of bumps or insufficient electrodeposition, among the cathode plates electrodeposited with purified metal by electrolytic purification. Without passing through the peeling device, the electrodeposited metal is peeled off from the defective cathode plate which is defective due to the normal cathode plate and the deformation of the cathode plate and the abnormality of the protector, and the electrodeposition poor cathode plate 1a which has not been peeled off. Another object of the present invention is to provide a method and system for removing and rejecting defective cathode plates, which can remove the defective cathode plate after stripping out of the system and increase the production efficiency of the entire electric copper plate recovery system. .

Selection is performed by stripping the electrodeposited metal with a stripping device for normal cathode plates without any markings and poorly shaped cathode plates with second markings, without passing through the stripped metal. The stripping process and the shape after the electrodeposition metal is stripped by the stripping device is transferred to the load-out conveyor by the second transfer device and the electrodeposited metal is stripped. The defective cathode plate and the electrodeposited defect cathode plate on which the electrodeposited metal has not been peeled off include a sorting step of transferring to a reject conveyor by the second transfer device. Board sorting To provide a removal method.

  In order to solve the above-mentioned problem, the present invention described in claim 2 is the method of selecting and removing defective cathode plates according to claim 1, wherein the first marking is green and the second marking is red. The first marking or the second marking is provided on the surface in the vicinity of one end of the cross bar of the cathode plate.

  In order to solve the above-mentioned problems, the present invention according to claim 3 is directed to a poorly electrodeposited cathode plate which has been poorly electrodeposited due to the formation of bumps or insufficient electrodeposition in metal electrorefining, deformation of the cathode plate, This is a system for sorting out and rejecting defective cathode plates that are defective due to an abnormality, and is a cathode plate with poor electrodeposition among a number of cathode plates that have been electrorefined and are conveyed by a load-in conveyor. The first marking previously attached to the predetermined portion of the first or the second marking of a color different from the first marking previously attached to the predetermined portion of the defective shape cathode plate is identified by the color identification means, and based on the identification result Marking detection means for detecting the presence or absence of marking and the difference in color and a stripping device for stripping the electrodeposited metal from the cathode plate detected by the marking detection means A first transfer device for transfer to the traverse conveyor to be sent, and an electrodeposition with the first marking on the cathode plate transferred to the traverse conveyor by the first transfer device and sent to the stripping device The defective cathode plate is allowed to pass through without stripping off the electrodeposited metal, and the electrodeposited metal is stripped of the normal cathode plate without any marking and the defective cathode plate with the second marking. The control means for controlling the stripping device, and the electrodeposited cathode plate detected by the marking detection means to be attached with the first marking are transferred to the first reject conveyor and eliminated, The normal cathode plate not marked and the poorly shaped cathode plate detected to have the second marking are transferred to the traverse conveyor to strip the electrodeposited metal. The first transfer device to be sent to the take-off means and the normal cathode plate after the electrodeposited metal is peeled off by the peeling device are transferred to the load-out conveyor and after the electrodeposited metal is peeled off. A defective cathode plate comprising: a poorly shaped cathode plate; and a second transfer device for transferring the electrodeposited defective cathode plate that has not been stripped of the electrodeposited metal to a jet conveyor. Provide a screening exclusion system.

  In order to solve the above-mentioned problem, the present invention described in claim 4 is characterized in that, in the system for sorting and eliminating defective cathode plates according to claim 3, the color identification means is a reflective color sensor.

  According to the method and system for sorting out and rejecting defective cathode plates according to the present invention, the electrodeposition failure cathode plate which has been poorly electrodeposited due to the occurrence of bumps or insufficient electrodeposition is not removed by the peeling device. Since it is allowed to pass through, it is possible to prevent troubles in the stripping apparatus caused by poorly electrodeposited electrode plates, thereby increasing the production efficiency of the entire electrolytic copper plate recovery system. .

  In addition, according to the method and system for selecting and rejecting defective cathode plates according to the present invention, after the electrodeposited metal is peeled off for the defective cathode plate which has become defective due to deformation of the cathode plate or abnormality of the protector, it is normal. Since the sorting and removal are performed separately from the cathode plate, there is an effect that the labor of sorting when the cathode plate is reused is eliminated.

  First, after describing the outline of the recovery system for an electroplated copper plate as a preferred embodiment of the electrodeposited metal recovery system in which the defective cathode plate sorting and eliminating method according to the present invention is incorporated, the defective cathode according to the present invention is described. An embodiment of a plate sorting and removing method and system thereof will be described. FIG. 2 is a schematic diagram of an embodiment of a recovery system for an electrolytic copper plate.

  The electrolytic copper plate recovery system 100 shown in FIG. 2 includes a load-in conveyor 101 for carrying a large number of cathode plates 1 with electrolytic copper 2 electrodeposited onto both surfaces thereof after electrolytic purification is completed, A cleaning device 102 that performs cleaning, and a cathode plate 1 that has been cleaned by the cleaning device 102 is transferred to a traverse conveyor 6 that transports the transport direction in the same direction as the longitudinal direction of the crossbar 4 without changing the posture. The transfer device 35a, the peeling device 103 that peels off the electrolytic copper 2 from the cathode plate 1, and the poorly electrodeposited cathode plate 1a, which has been poorly electrodeposited due to the occurrence of bumps K or insufficient electrodeposition, are not stripped off. A control device for controlling the operation of the stripping device 103 so as to strip only the defective cathode plate 1b which has been made defective due to normal cathode plate 1 and deformation of the cathode plate 1 or abnormality of the protector. 27, the cathode plate 1 after the copper electrode 2 is peeled off from the poorly electrodeposited cathode plate 1a and the poorly shaped cathode plate 1b is transferred to the reject conveyor 8 and removed out of the system, and the normal cathode plate 1 Was superposed on a second transfer device 35b for transferring it to the load-out conveyor 104 for collecting it, and a polymerization device 107 for superposing two pieces of peeled plate-like copper 2 in a set. An electrolytic copper plate conveying device 106 that conveys the electrolytic copper 2, a press device 108 that performs flat press and corrugation while being conveyed by the electrolytic copper plate conveying device 106, and a predetermined number of electrolytic coppers 2 that have been pressed are stacked and weighed. And a copper plate unloading unit 109 for packaging after performing labeling, marking, etc., and collecting the electrolytic copper 2 after packing.

  Next, the outline | summary of operation | movement of this collection | recovery system 100 of an electrical copper plate is demonstrated. First, a large number of cathode plates 1 that have been subjected to electrolytic purification are carried into a load-in conveyor 101 while being suspended by a crane (not shown). A large number of loaded cathode plates 1 are transported to the cleaning device 102 while being transported in a direction perpendicular to the surface of the cathode plate 1 by the load-in conveyor 101 and are simultaneously cleaned every predetermined number of sheets. The cleaned cathode plate 1 is transferred to the traverse conveyor 6 by the first transfer device 35a, and this time the transport direction of the cathode plate 1 is parallel to the surface of the cathode plate 1 (that is, the axis of the crossbar 4). The sheet is continuously conveyed toward the peeling device 103 one by one.

  When the cathode plate 1 conveyed to the stripping device 103 by the traverse conveyor 6 is a poorly electrodeposited cathode plate 1a, the control device 27 passes the copper as it is without stripping the electrolytic copper 2, which is a normal cathode. The stripping device 103 is operated only in the case of the poorly shaped cathode plate 1b of the plate 1 or the cathode plate 1, and the stripping device 103 is controlled so that the electrolytic copper 2 is stripped from both surfaces. Then, the poorly electrodeposited cathode plate 1a that has not been stripped and the normal cathode plate 1 and the poorly shaped cathode plate 1b that have been stripped of the electrical copper 2 are further fed in the direction of the load-out conveyor 104 by the traverse conveyor 6. . Then, the control device 27 further transfers the normal cathode plate 1 to the load-out conveyor 104, and the defectively shaped cathode plate 1b and the poorly electrodeposited cathode plate 1a are transferred to the reject conveyor 8 and excluded from the system. The movement of the second transfer device 35b is controlled. As a result, the normal cathode plate 1 is again subjected to electrolytic purification, and the poorly electrodeposited cathode plate 1a removed to the second reject conveyor 8 is manually stripped of the electrolytic copper 2 and has a poorly shaped cathode. The plate 1b is subjected to shape correction or repair / replacement of the protector 5.

  The electrolytic copper 2 peeled off from the cathode plate 1 is superposed on a set of two sheets by the polymerization apparatus 107, and is joined and fixed by an appropriate method at least at two or more positions. To be transferred. The electrolytic copper 2 superposed on a set of two sheets is flat pressed and corrugated by the press device 108 while being transported by the electrolytic copper transport device 106. Then, the electrolytic copper 2 that has been pressed is loaded and weighed by a predetermined number, and after labeling, marking, etc., it is packed and recovered from the copper plate carry-out section 109.

  Now, the defective cathode plate sorting and eliminating system according to the present invention functions the recovery system 100 for an electrolytic copper plate that performs the above-described configuration and operation. First, a large number of cathode plates 1 that have been subjected to electrolytic purification and have been carried in by the load-in conveyor 101 are poorly electrodeposited cathode plates 1a that are considered to be poorly electrodeposited due to the formation of bumps K, insufficient electrodeposition, etc. The presence or absence of a poorly shaped cathode plate 1b, which is considered to be defective due to deformation of the plate or an abnormality of the protector, is confirmed. The poorly electrodeposited cathode plate 1a is red as a first marking near one end of the crossbar 4. Marking M1 is given. The poorly shaped cathode plate 1b is provided with a green marking M2 as a second marking different from the color (red) attached to the poorly electrodeposited cathode plate 1a. If the cathode plate 1 is a poorly electrodeposited cathode plate 1a and corresponds to the poorly shaped cathode plate 1b, both may be marked, but the red marking M1 indicating the poorly electrodeposited cathode plate 1a is given priority. It is preferable to attach.

  Here, whether the cathode plate 1 is good or bad is determined by visual observation, and the surface of the cathode plate 1 has a bump K having a predetermined height or the thickness of the electrolytic copper 2 has not reached the predetermined thickness. It is judged as bad. In this case, the standard of good or bad is slightly different depending on the acceptable level of the product shipping destination, but in the normal case, the surface of the cathode plate 1 has a bump K having a height H (for example, 10 mm) or more. This occurs based on whether the surface is generated with an area of 40% or more with respect to the entire surface, or whether the thickness of the electrolytic copper 2 is 5 mm or less. And the red marking is attached | subjected as the 1st marking M1 to the predetermined location of the electrodeposition defect cathode plate 1a, for example, the edge part vicinity of the one side of the crossbar 4. FIG. On the other hand, in the case of the poorly shaped cathode plate 1b which is considered to be defective due to deformation of the cathode plate 1 or abnormality of the protector, a green marking is attached as the second marking M2 near the end on one side of the cross bar 4. . Good or bad standards in this case are based on whether the cathode plate 1 is curved ± 20 mm or more in the thickness direction or the protector 5 is not damaged or peeled off.

  A color sensor as a color identification means for detecting the presence or absence of a marking M1 or M2 attached to the vicinity of the end of the cross bar 4 of the cathode plate 1 in a transported state and a color difference at a predetermined position that has passed through the cleaning device 102 31 and the color identified by the color sensor 31 are analyzed to detect whether the cathode plate 1 is normal, or whether it is a poorly electrodeposited cathode plate 1a or a poorly shaped cathode plate 1b by the marking detecting means 33. As a result, a control device 27 for controlling the operations of the peeling device 103 and the second transfer device 35b is provided.

  The color sensor 31 is a reflective color sensor, and a light emitting element and a light receiving element (not shown) are arranged facing the vicinity of the end of the crossbar 4 with the marking M1 or M2. Then, when the vicinity of the end of the crossbar 4 passes through the optical path, the light emitted from the light emitting element is reflected by the end of the crossbar 4 and the reflected light is received by the light receiving element, so that the change is captured. Detect differences. As the color sensor 31, for example, “CZ-V21” (trade name) of Keyence Co., Ltd. (1-3-14 Higashinakajima, Higashiyodogawa-ku, Osaka) can be used. Note that the color identification means may be configured to take a color with a color sensor and determine the color based on the contrast difference of the image.

  Although not shown, the control device 27 is a central processing which performs various information processing based on various devices constituting a general-purpose computer, for example, a storage device such as a memory for storing data, and a program recorded in the storage device. The apparatus includes an input device such as a keyboard for inputting necessary data, a display device for displaying a processing status on a screen, and a communication device for transmitting and receiving data to and from the control device 27. In addition, since these vices are well-known, description here is abbreviate | omitted.

  As shown in FIG. 4, the control device 27 has a program for causing the marking detection means 33 described above to function based on the color identified by the color sensor 31 in the computer constituting the control device 27. It is mounted and the presence or absence of the markings M1, M2 and whether it is the first marking M1 or the second marking M2 are detected by the marking detection means 33 configured in the control device 27. And when M1 which is 1st marking is detected by the marking detection means 33, the control apparatus 27 will judge that it is the electrodeposition defect cathode plate 1a, and the stripping apparatus 103 of electrolytic copper 2 is determined. Control is performed so as to pass through without stripping. On the other hand, when it is determined by the marking detection means 33 that the marking is not applied or when the second marking M2 is detected, the control device 27 detects that the normal cathode plate 1 or the defective shape cathode plate 1b. Therefore, the stripping device 103 is controlled to strip the electrical copper 2.

  The control device 27 is further configured to send a control signal to the second transfer device 35b. That is, when the cathode plate 1 conveyed by the traverse conveyor 6 through the stripping device 103 is a poorly electrodeposited cathode plate 1a and a poorly shaped cathode plate 1b, the poorly electrodeposited cathode plate 1a and the poorly shaped cathode plate 1b. Is transferred to the reject reject conveyor 8 and controls the operation of the second transfer device 35b so that the cathode plate 1 is transferred to the load-out conveyor 104.

  Here, the detection of the presence or absence of marking by the marking detection means 33 and the detection of the first marking M1 and the second marking M2 are specifically detected signals near the end of the crossbar 4 identified by the color sensor 31. This is done by detecting a change in contrast based on the difference between the two. Therefore, it is preferable that the first marking M1 and the second marking M2 have colors different from the crossbar 4 as much as possible in color tone, brightness, and saturation, and the first marking M1 and the second marking M2 Colors that make the difference as clear as possible are preferred. This is because the marking on such a color tone gives a clear contrast on the identified color and improves the identification accuracy. Examples of preferable colors include combinations of red and green, yellow and blue, and the like. In order to prevent erroneous detection of the color sensor 31 due to the influence of the weather or day and night, it is preferable to install illumination and keep the conditions of the identification part constant.

  Specifically, the marking detection means 33 has a function of digitizing color information from the detection signal identified by the color sensor 31 according to the contrast of the corresponding portion. For example, in the case of no coloring (normal), “0 In the case of red with poor electrodeposition, the numerical value is set to “1”, and in the case of green with poor shape, “2”. Then, each cathode plate 1 is assigned a corresponding numerical value (0, 1, 2) for classification. On the other hand, in the case of a poorly electrodeposited cathode plate 1a with “1” attached to the control device 27, it is allowed to pass through without being removed, and a normal cathode plate 1 or “2” with “0” attached is passed. In the case of the attached poorly shaped cathode plate 1b, a control program for sending a control signal for controlling the stripping device 103 so as to strip the electrolytic copper 2 is provided.

  Further, in the case of the normal cathode plate 1 with “0” attached to the control device 27, it is transferred to the load-out conveyor 104, and the uncoated electrodeposited defective cathode plate 1a with “1” attached is transferred. And a control program for sending a control signal for operating the second transfer device 35b so as to be transferred to the reject conveyor 8 in the case of the badly shaped cathode plate 1b after being peeled off with “2” attached. Is provided. The poorly electrodeposited cathode plate 1a determined to be poorly electrodeposited in this way is allowed to pass through the stripping device 103 without being stripped by the stripping device 103, and after being stripped from the poorly electrodeposited cathode plate 1a. The defective shape cathode plate 1b is removed by being transferred to the reject conveyor 8 by the second transfer device 35b, and only the normal cathode plate 1 can be transferred to the load-out conveyor 104 for reuse. . The cathode plate 1 colored red or green is erased by an electric sander in the correction chamber.

  Next, a preferred embodiment of the defective cathode plate sorting and eliminating method according to the present invention will be described together with the operation of the above-described defective cathode plate sorting and eliminating system. First, a poorly electrodeposited cathode plate in which the electrodeposition state is poor due to the occurrence of bumps K or the lack of electrodeposition of a large number of cathode plates 1 that have been electrolytically refined and have been transported to the load-in conveyor 101. 1a and the presence or absence of a badly shaped cathode plate 1b which is considered to be defective due to deformation of the cathode plate or abnormality of the protector, and the first electrode near the one end of the crossbar 4 is in contact with the poorly electrodeposited cathode plate 1a. A red marking M1 is given as the marking, and a green marking M2 is given as the second marking on the poorly shaped cathode plate 1b. (Step S1).

  A large number of cathode plates 1 for which the marking operation has been completed are cleaned by the cleaning device 102 while being conveyed by a load-in conveyor, and then the color sensor 31 as a color identification means identifies the vicinity of the end of the crossbar 4. Performed (step S2), the presence or absence of markings M1 and M2 and the difference in their colors are detected (step S3). The detection is performed by analyzing the color identified by the color sensor 31 by the marking detection means 33 configured by a program installed in a computer constituting the control device 27. Thereby, the presence / absence of the markings M1, M2 and whether it is the first marking M1 or the second marking M2 are determined. When the marking detection means 33 detects M1 which is the first marking, the control device 27 sends a control signal to the stripping device 103a without passing the stripped electrode plate 1a. Send (step S4). On the other hand, when it is detected by the marking detection means 33 that no marking is applied and when the second marking M2 is detected, the control device 27 detects the normal cathode plate 1 and the stripping device 103a. A control signal is sent so as to strip off the electrolytic copper 2 from the poorly shaped cathode plate 1b (step S5). By this selective stripping process, the electrolytic copper 2 is not stripped from the poorly electrodeposited cathode plate 1a, so that trouble of the stripping device 103 is prevented.

  The normal cathode plate 1 and the poorly shaped cathode plate 1b after the stripping of the electrolytic copper 2 and the poorly electrodeposited cathode plate 1a that has not been stripped are further conveyed by the traverse conveyor 6, but the control device Reference numeral 27 denotes a reject conveyor 8 in the case of the untransferred electrodeposited bad cathode plate 1a with the first marking M1 and the badly shaped cathode plate 1b after being peeled off with respect to the second transfer device 35b. In the case of a normal cathode plate 1 that has not been marked, the control signal is sent so that it is transferred to the load-out conveyor 104, and the second transfer is performed. The operation of the mounting device 35b is controlled (step S6). As a result, the non-stripped electrodeposition defective cathode plate 1a and the stripped defective cathode plate 1b are removed from the system by the reject conveyor 8 (step S7), and the normal cathode plate 1 is recovered by the load-out conveyor 104. And reused for electrolytic purification. Incidentally, the poorly electrodeposited cathode plate 1a excluded from the system is manually stripped of the electrolytic copper 2, the defective electrolytic copper 2 is reused as a cold material, and the cathode plate 1 is used for electrolytic purification. Reused. On the other hand, the poorly shaped cathode plate 1b is subjected to electrolytic refining again by correcting distortion or bending or replacing the protector 5.

  As described above, according to the method and system for selecting and removing defective cathode plates according to the present invention, troubles in the stripping apparatus 103 caused by the electrodeposition defect electrode plate 1a can be prevented in advance. Since there is no need for sorting when the plate 1 is reused, it is possible to increase the production efficiency of the entire recovery system for the electrolytic copper plate.

  As described above, preferred examples of the present invention have been described in detail, but the present invention is not limited to such specific embodiments, and within the scope of the gist of the present invention described in the claims, Needless to say, various modifications and changes are possible.
