Description

  The present invention relates to a defective electrode plate sorting apparatus and a defective electrode plate sorting method, and more specifically, a cathode plate electrodeposited with refined metal by electrolytic smelting is transported to a stripping means by a traverse conveyor, and the stripping means is used. When the electrodeposited metal is peeled off from the cathode plate and collected, the cathode plate that is considered to be defective due to the occurrence of bumps or bending is removed before being transferred to the traverse conveyor, and the selection of the good electrode plate. Regarding the method.

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

  For example, JP-A-2005-240146 (Patent Document 1) is known as a conventional electrolytic copper plate recovery system.

  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 conveyed to the cleaning device in a suspended state, and is simultaneously cleaned every predetermined number of sheets. 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.

The loaded plywood A is transported to the cleaning device 102 while being transported in a direction perpendicular to the surface of the plywood A by a transport conveyor (not shown). Then, the plywood A is simultaneously cleaned by the cleaning device 102 every predetermined number of sheets. The cleaned plywood A is transported by a transport conveyor (not shown), and is then transferred to the traverse conveyor 6 to deflect the transport direction of the plywood A in a direction parallel to the plywood surface (that is, the axial direction of the crossbar 4). Then, each sheet is continuously conveyed to the peeling device 103.

  When the stripping device 103 receives the plywood A one by one, it peels off the copper 2 from the cathode plate 1 to separate them, and the cathode plate 1 is sent to the cathode plate carry-out section 104 and again used for electrolytic smelting. It is made.

FIG. 3 shows an embodiment of a defective electrode plate sorting apparatus according to the present invention.
The illustrated defective electrode plate sorting apparatus 10 includes a first sorting apparatus 11 and a second sorting apparatus 12.
First, when the first sorting device 11 passes the cathode plate 1 in which the bump 9 having a height h or more which is considered to be defective is generated at the bottom of the cathode plate 1 (plywood A) on which the electrolytic copper 2 is electrodeposited. 3 is in contact with the bump 9 and thereby pushed down in the transport direction of the cathode plate 1 (X direction in FIG. 3), and returned to its original position after the cathode plate 1 has passed. A check plate 20, a magnetic generator 23 disposed so as to tilt in conjunction with the depression of the check plate 20, and a magnetic detector 25 for detecting magnetism generated from the magnetic generator 23. The magnetic detector 25 that detects a change in the magnetic field caused by the tilting of the magnetic generator 23 in conjunction with the depression of the magnetic field, and the cathode plate that has been determined to be defective based on the detection result detected by the magnetic detector 25. Reject without transferring to Excluding device 27 for excluding the conveyor 7 side is constituted by a (see FIG. 5). The first sorting device 11 is arranged on the front side of the traverse conveyor 6 and on the lower side of the conveying means for conveying the plywood A to the traverse conveyor 6 (see FIG. 2).

  As shown in the figure, the check plate 20 is a plate-like member having a length longer than the length in the width direction of the plywood A, and is arranged on both the left and right sides by shafts 20a provided on the left and right lower sides. The base 21 is rotatably supported. With this configuration, the check plate 20 can be pushed down in the conveyance direction (X direction) of the plywood A around the shaft 20a. The check plate 20 is provided with a return mechanism (not shown) by means such as a spring, for example, and is formed so as to always stand up (state shown in FIG. 3) when no force is applied. ing. Thus, when the plywood A passes above the check plate 20, the bump 9 generated at the bottom of the plywood A contacts the check plate 20, so that the check plate 20 is pushed in the X direction, which is the conveyance direction of the plywood A. After the plywood A passes, the check plate 20 rises again by a return mechanism (not shown) and returns to its original state. Here, in the electrolytic refining, since a highly reactive electrolytic solution such as a copper sulfate solution is used, the check plate 20 is preferably made of stainless steel, for example, a material having corrosion resistance such as SUS316.

  The clearance between the upper end surface of the check plate 20 and the lower end portion of the plywood A passing over the check plate 20 is preferably at least 10 mm. As a result, it is possible to eliminate the plywood A in which the lower edge 9 of the height h of 10 mm or more is generated at the bottom of the plywood A as defective. And the magnitude | size of the lower bump 9 which should be excluded can be adjusted by changing a clearance suitably.

  On either one of the shafts 20 a supported by the base portion 21, a magnetic generator 23 that is tilted in conjunction with the pushing of the check plate 20 is disposed.

In addition, when the check plate 20 is pushed down, the magnetism generator 23 is also tilted in conjunction with the check plate 20 and is located away from the magnetism detector 25 (see FIG. 4). ). And when the magnetic detector 25 detects the change of the magnetism accompanying the change of the position of the magnetic generator 23, the plywood A in which the bump 9 is generated on the lower side passes above the check plate 20. to decide. It should be noted that any change in the position of the magnetic generator 23 caused by the check plate 20 being pushed down may be detected by the magnetic detector 25, and the present invention is not limited to this embodiment.

The detection signal detected by the magnetic detector 25 is sent to the control device 27, and the control device 27 that has received the detection signal rejects the plywood A without transferring it to the traverse conveyor 6. An exclusion signal instructing to be sent to the conveyor 7 side is sent to the exclusion device 35. The rejecting device 35 is configured to transfer the plywood A determined to be defective based on the rejection signal sent from the control device 27 to the reject conveyor 7 without transferring it to the traverse conveyor 6.
The control device 27 is configured by a general-purpose computer, and includes a storage device such as a memory for storing data, a central processing unit for performing various information processing based on programs recorded in the storage device, and input of necessary data. An input device such as a keyboard to be performed, a display device that displays a processing status on a screen, and a communication device that transmits and receives data to and from the control device 27 are provided. In addition, since these structures are well-known, description here is abbreviate | omitted.

Next, the second sorting device 12 will be described. The second sorting device 12 is disposed on the front side of a transport means (not shown) that transports the plywood A to the traverse conveyor 6. The second sorting device 12 includes a camera 31 that is a photographing device that photographs the plywood A in the transport state, and a marking detection unit 33 that analyzes a video photographed by the second sorting device 12 and detects a defective electrode plate. And a rejecting device 35 that sends the defective plywood A to the reject conveyor 7 side without being transferred to the traverse conveyor 6.
The plywood A in which a bump having a predetermined height is generated on the surface or the flatness is hindered and the curvature is generated is determined in advance by visual inspection. The marking M is previously attached to the vicinity of the end portion on one side of 4. As a criterion for good or bad, it is performed based on whether a bump having a height of 10 mm or more is generated on the surface of the plywood A, or whether the plywood A is curved with a width size of ± 20 mm or more in the thickness direction.

When a defective plywood A previously marked with a marking M is conveyed, the presence or absence of the marking M is detected by detecting a change in contrast in an image taken by the camera 31. Here, it is preferable that the marking M has a color different from the crossbar 4 in color tone, brightness, and saturation as much as possible. This is because the contrast on the photographed image is clear and the identification accuracy is improved. Preferred colors include, for example, yellow or blue. In order to prevent erroneous detection of the camera due to the influence of the weather or day and night, it is preferable to install illumination so as to keep the shooting conditions at the shooting location constant.
The marking detection means 33 in the present embodiment is provided as a program that exhibits its function in the computer that constitutes the control device 27 in the first sorting device 11, but may have a different configuration. When the marking M is detected by the marking detection means 33 configured in the control device 27, the control device 27 sends an exclusion signal to the exclusion device 35 as in the case of the first sorting device 11, The plywood A is not transferred to the traverse conveyor 6 but sent to the reject conveyor 7 side. Thus, the plywood A determined to be defective can be eliminated without being transferred to the traverse conveyor 6.

Next, the defective electrode plate sorting method according to the present invention will be described together with the operation of the electrode plate sorting device 10 configured to include the first sorting device 11 and the second sorting device 12 described above.
First, the plywood A that has undergone electrolytic refining is inspected visually to inspect the surface for the presence of bumps 9 and bends that exceed the reference, and at a predetermined location of the crossbar 4 of the plywood A that is determined to be defective. Yellow indicating that it is defective is colored (step S1).
A plurality of plywood A including the colored defective plywood A is conveyed toward the traverse conveyor 6 by a conveyance conveyor (not shown). At this time, the plywood A passes one after another on the first sorting device 11 arranged in front of the traverse conveyor 6, but the plywood A in which the bump 9 having a size larger than the reference is generated on the lower side. , The bump 9 comes into contact with the check plate 20, and the check plate 20 is pushed down in the traveling direction (X direction) side of the plywood A. As a result, the magnetic generator 23 attached to the shaft 20 a of the check plate 20 also tilts in conjunction with the check plate 20 and reaches a position away from the magnetic detector 25. Then, the magnetic detector 25 detects a change in magnetism and sends a detection signal to the control device 27 (step S2). Receiving the detection signal from the magnetic detector 25, the control device 27 sends a rejection signal to the rejection device 35 (step S3), and the rejection device 35 does not transfer the plywood A to the traverse conveyor 6 and rejects it. Send to the reject conveyor 7 side. As a result, the plywood A determined to be defective is removed without being transferred to the traverse conveyor 6 (step S4).

  On the other hand, when the plywood A with the yellow marking M is conveyed to the crossbar 4, the marking detection means 33 provided in the control device 27 detects the difference in contrast in the image taken by the camera 31. Then, as in the case of the first sorting device 11, an exclusion signal is sent to the exclusion device 35 (step S3). As a result, the reject device 35 sends the plywood A to the reject conveyor 7 side without being transferred to the traverse conveyor 6. As a result, the plywood A determined to be defective is removed without being transferred to the traverse conveyor 6 (step S4).

  As described above, according to the defective electrode plate sorting apparatus and the defective electrode plate sorting method according to the present invention, not only can the conveyance trouble in the traverse conveyor caused by the defective electrode plate be prevented in advance, but also the failure. By eliminating the trouble of handling the transport trouble on the traverse conveyor caused by the electrode plate, it is possible to improve the work efficiency of the entire electrolytic copper plate collection system.
