Description

  The present invention relates to a transfer device and a transfer method that are suitable for use in a transfer path for continuously flexing and peeling a deposited metal plate in which a pair of pure copper plates are deposited on both sides of a cathode electrode, for example.

  For example, in the electrolytic refining of copper called the ISA method, a direct current is passed from a crude copper anode electrode to a stainless steel cathode electrode in a copper sulfate solution in an electrolytic bath using a stainless steel cathode electrode. The copper content in the anode or the copper content in the electrolytic solution is ionized and transferred to the cathode, and pure copper is deposited on both sides of the cathode electrode.

  FIG. 5 shows a cathode electrode 22 of a stainless steel plate that has been conventionally used.

  In the cathode electrode 22, in order to facilitate the removal of the pure copper plate to be deposited, a V-shaped groove 24 is formed on the lower end surface of the stainless steel plate 22a, and plastics or the like are formed on both side edges of the stainless steel plate 22a. A band plate 26 made of an insulating material is disposed, and this band plate 26 prevents pure copper from being deposited on both side edges of the stainless steel plate 22a.

  The cathode electrode 22 of such a stainless steel plate is alternately arranged in an electrolytic cell filled with an electrolytic solution together with an anode electrode made of crude copper or an anode as a mere electrode, and a current is applied to the surface of the cathode electrode 22. Pure copper is deposited. When the cathode electrode 22 reaches a certain weight, the cathode electrode 22 is pulled up from the electrolytic cell and conveyed through the first conveyance path, and then transferred to the second conveyance path orthogonal to the first conveyance path. Then, while proceeding through this second transport path, in this second transport path, as shown in FIGS. 6A and 6B, pure copper plates (hereinafter simply referred to as “deposited copper plates” deposited on both surfaces of the cathode electrode 22). In order to peel the 28, 28 from the stainless steel plate 22a of the cathode electrode 22 by alternately pressing the rods 23a, 23b of the cylinder devices 23A, 23B arranged on the sides, the stainless steel plate 22a and a pair of copper plates A gap is generated between the two. And as shown in FIG. 7, the copper plates 28 and 28 are stripped from the stainless steel plate 22a by pushing down the stripper 30 such as a wedge downward from above.

  By the way, in the case where a large amount of pure metal such as copper is produced in an electrolytic cell, it is necessary to perform these treatments continuously. Therefore, the framing process shown in FIGS. 6A and 6B or the peeling process shown in FIG. 7 is continuously performed in the same conveyance path with a predetermined interval, and the framing process is performed at the first stage. Is carried to the next second stage where stripping is performed.

  Thus, the deposited metal plate (herein, the deposited metal plate refers to the copper plate 28 deposited on the stainless steel plate 22a as an electrode. In this specification, the copper plate is disposed on both sides of the stainless steel plate 22a serving as the cathode electrode. As a transport path for continuously transporting the three-layered structure on which 28 and 28 are deposited is also referred to as a deposited metal plate. Conventionally, a chain conveyor has been adopted.

However, this chain conveyor has a problem in that, in addition to generating a large noise, chain elongation occurs. The deposited metal plate is fixed to the chain conveyor by providing a guide plate on the chain conveyor and aligning the guide plate with the guide plate. However, when the chain is extended, accurate alignment cannot be performed. Further, there has been a problem that the deposited metal plate cannot be held in a stable posture. Further, since the chain conveyor is expensive, there is a problem that the cost becomes high.

  On the other hand, in consideration of such a problem of the chain conveyor, a conveying means that does not use the chain conveyor is also provided.

  FIG. 8 shows a conventional transport device that does not use the chain conveyor disclosed in Patent Document 1. In FIG.

  In this transport apparatus, the supply line 4 and the discharge line 15 at both ends extend in a direction perpendicular to the paper surface, and a horizontal transport path including intermediate stages 5, 6 and 7 in order is formed between them. Yes.

  This transport path is composed of a long frame 2 and a transport bar 3 which is longer in length than the frame 2 and can be reciprocated in the horizontal direction on the frame 2. For example, by moving one stage from the left in the figure to the right in the figure, the four cathodes 8, 9, 10, and 11 simultaneously move one stage in the lateral direction. That is, due to the horizontal movement of the transfer bar 3, the cathode 8 in the supply line 4 moves to the first stage 5, the cathode 9 in the first stage 5 moves to the second stage 6, and the second The cathode 10 in the stage 6 moves to the third stage 7. Further, the cathode 11 in the third stage 7 moves to the discharge line 15.

  In FIG. 8, the cathodes 8, 9, 10, and 11 are shown floating from the transport bar 3, but are in contact with the upper surface of the transport bar 3 during actual movement in the right direction. It is being conveyed by.

  As described above, in Patent Document 1, the four cathodes 8, 9, 10, and 11 are moved by the movement of the transport bar 3. For example, the flexing process of FIG. 6 is performed in the first stage 5, and the stripping process of FIG. 7 is performed in the second stage 6.

Special Table 2002-525439

  By the way, in the conventional conveying apparatus which does not use a chain conveyor in this way, once the cathodes 8, 9, 10, and 11 are once conveyed rightward by the conveying bar 3, the conveying bar 3 is returned to the original initial position, that is, near the left end. Needs to be returned to the position of the supply line 4.

  In the conventional transfer apparatus, as shown in FIG. 8, the cathodes 8, 9, 10, and 11 are slightly lifted upward using the lifters 12, so that these cathodes 8, 9, 10, and 11 are transferred to the transfer bar. It floated away from 3.

  However, since the cathodes 8, 9, 10, and 11 are conventionally lifted from above when separating the cathodes 8, 9, 10, and 11 from the transport bar 3, the flexing process shown in FIG. In the peeling stage, when the copper plates 28 and 28 on both sides are completely detached from the stainless plate 22a, there is a problem that only the stainless plate 22a is lifted and the copper plates 28 and 28 on both sides fall downward. It was. In such a case, troubles occur in the conveyance, and the continuous operation must be stopped.

  In view of such circumstances, the present invention is a case where a plurality of deposited metal plates are simultaneously transported in the horizontal direction as one block without using a chain conveyor like a transport bar, and the transport body as the block In returning the (walking beam in the case of the present invention) to the original initial position, both the deposited metal plate and the plate member as the electrode can be surely lifted, so that only the walking beam is returned to the initial position for continuous operation. It aims at providing the conveyance apparatus and conveyance method of the deposit metal plate which can be performed continuously.

In order to achieve the above object, a transport apparatus for a deposited metal plate according to the present invention,

A plurality of the deposited metal plates placed on the first stage, the second stage,..., The Nth stage are simultaneously horizontalized by the walking beam disposed below the deposited metal plate. And the movement of the walking beam is stopped when the deposited metal plate is transferred to the next stage, and the tip of the lifting lever is subsequently moved into the recess of the walking beam. Further, by moving only the lifting lever upward, the deposited metal plate is lifted away from the walking beam, while the deposited metal plate is lifted away from the walking beam. It is characterized by only returning the walking beam to its original position after being in a state

Moreover, the method for conveying the deposited metal plate according to the present invention is as follows.

It is characterized by only returning the walking beam to its original position after being in a state

  Here, in the method of the present invention, it is preferable that the lifting lever is placed in a standby state when the deposited metal plate is conveyed by the walking beam.

  According to such a conveying apparatus and conveying method, since a plurality of deposited metal plates are simultaneously moved in the horizontal direction by moving the walking beam as one block instead of using a chain conveyor, the generation of noise is minimized. It can be suppressed and can be configured at low cost. Also, when returning the walking beam to the original initial position, the deposited metal plate is lifted from below by the lower lifting lever instead of from above, so that the deposited metal plate can be lifted reliably, and thus the walking beam can be lifted. Only can be returned to the initial position.

  Hereinafter, preferred embodiments of a transport apparatus and a transport method for a deposited metal plate according to the present invention will be described with reference to the drawings.

  FIG. 1 shows an outline of a deposited metal plate conveying apparatus according to an embodiment of the present invention.

  The apparatus and method for transporting a deposited metal plate according to the present invention can be applied to transporting a deposited metal plate from any place in a factory to any place, in particular, as shown in FIG. As shown in FIG. 7, the flexing process for forming a gap between the stainless steel plate 22a and the copper plate 28, and the peeling process of the copper plate 28 by the stripper 30 are performed on the conveyance path for continuously performing the process. It can be preferably applied.

  First, the cathode electrode employed in one embodiment of the present invention is the same as the cathode electrode 22 of FIG.

  That is, the cathode electrode 22 of the present invention is attached to a horizontal support member 23 called a hanger in a posture in which a substantially rectangular stainless steel plate 22a hangs down in the vertical direction.

  As described above, the cathode 22 electrodes are alternately arranged in the electrolytic bath filled with the electrolyte together with the anode electrode, and when current is passed, for example, pure copper is deposited on the surface of the stainless steel plate 22a. The cathode electrode 22 on which pure copper plates 28 and 28 having a predetermined weight are deposited on both surfaces is pulled up from the electrolytic cell. As shown in FIG. 1, the cathode electrode 22 pulled up from the electrolytic cell is linearly transported along the first transport path 50, and the first transport is performed at the terminal portion of the first transport path 50. It is delivered to a second transport path 52 formed in a direction orthogonal to the path 50. And in this 2nd conveyance path 52, a flexing process and a peeling process are performed.

  A place where the flexing in the second conveyance path 52 is performed is a first stage 54, and a place where peeling is performed is a second stage 56. In this way, the cathode 22 on which the copper plate is deposited is subjected to one process in the second transport path 52 and then sent to the next stage on the downstream side, where the next process is performed. Finally, it is transferred from the discharge stage 74 to the third transport path 58.

  In FIG. 1, a transport path 60 that faces the first transport path 50 and a transport path 62 that faces the third transport path 58 show those reject lines. The cathode 22 which does not reach is discharged from here. Further, in the reject line 62, when there is a defect in the stainless steel plate 22a after the deposited metal plate 28 is peeled off, it is transported to this line and carried to the repair process.

  Further, in FIG. 1, if a robot arm 64 is provided to transfer the anode 22 from the first transport path 50 to the second transport path 52, or the second transport path 52 to the third transport path 58. If the robot arm 66 is provided to transfer the copper plate 28 or the stainless steel plate 22a to the plate, these transfer operations can be automated.

  FIG. 2 shows the second conveyance path 52.

  That is, as shown in FIG. 2, the second transport path 52 has a frame 68 that cannot move, and a plate-like walking that is movable on the frame 68 in the direction of arrow AA ′ with a roller or the like. And a beam 70. The walking beam 70 is longer than the frame 68.

  The walking beam 70 has a receiving stage 72 for receiving the cathode 22 from the first conveying path 50 shown in FIG. 1 at one end thereof, and receives the copper plate 28 in the third conveying path 58 at the other end. A delivery discharge stage 74 is provided. Further, a first stage 54 for performing flexing and a second stage 56 for separating the copper plate 28 are provided between the receiving stage 72 and the discharging stage 74. You may have to the Nth stage for performing a process. On each of these stages 72, 54, 56, 74, a laminated plate composed of a pair of copper plates 28, 28 deposited in an electrode and an electrolytic cell is supported in an upright state as shown.

  In the following description, even a laminated plate having a three-layer structure in which copper plates 28 and 28 are deposited on the stainless steel plate 22a is described as a deposited metal plate 28a.

  In the second conveyance path 52, as shown in FIG. 2, four deposited metal plates 28 are placed on each stage on the long walking beam 70, and this state is an initial state. From this initial state, if the walking beam 70 is made into one block, for example, if it is moved in the direction of arrow A ′ by driving a hydraulic cylinder or rack and pinion, etc., the four deposited metal plates 28 on the walking beam 70, 28, 28, 28 can be moved simultaneously in the direction of arrow A ′. At this time, if the moving distance of the walking beam 70 is set to one stage width, all the deposited metal plates 28 are shifted to the downstream side of one stage. Note that the walking beam 70 moves on the frame 68 via a support mechanism such as a bearing and a roller, so that noise is hardly generated. Also, by this movement, the deposited metal plate 28 on the receiving stage 72 is moved to the first stage 54, the deposited metal plate 28 on the first stage 54 is moved to the second stage 56, and the deposited metal on the second stage 56 is moved. The plate 28 can be moved to the discharge stage 74, respectively. The deposited metal plate 28 on the discharge stage 74 is separated from the stainless steel plate 22a, and the copper plates 28 and 28 are transferred to the third transport path 58 shown in FIG. Further, the stainless steel plate 22 a is conveyed to the reject line 62.

  In this way, the four deposited metal plates 28 on each stage move one stage downstream. Then, the deposition metal plate 28 moved to the first stage 54 is flexed, and the deposition metal plate 28 moved to the second stage 56 is peeled off.

  Thus, in order to process the deposition metal plate 28 continuously without interruption, it is necessary to return the walking beam 70 in the direction of arrow A each time after the deposition metal plate 28 is moved by one stage. In that case, the deposited metal plate 28 must be slightly lifted from the walking beam 70 to make the walking beam 70 free from the deposited metal plate 28.

  In this way, in order to separate the walking beam 70 from the deposited metal plate 28, the following mechanism is employed in this embodiment.

  FIG. 3 and FIG. 4 show a deposited metal plate conveying apparatus 80 according to the present invention, which is provided with a mechanism for lifting the deposited metal plate 28 slightly upward.

  The transport apparatus 80 for a deposited metal plate according to one embodiment of the present invention is movable in the direction of arrow A-B 'and is movable in the direction of arrow B-B' and in the direction of arrow C-C '. The lift lever 73 is swingable. Such a lifting lever 73 is accommodated in a recess 77 formed in the walking beam 70 at a predetermined timing, and the lifting levers 73 and 73 move in the direction of arrow B (upward) with respect to the walking beam 70. Thus, for example, the deposited metal plates 28, 28 arranged on the first stage 54 can be lifted upward from below. Therefore, in this embodiment, even when the stainless steel plate 22a and the pair of copper plates 28 are completely separated, the three-layer laminate can be lifted upward without dropping the copper plate 28.

  The lifting lever 73 has a tip portion that is substantially flat and bent in the middle, and a V-groove 75 is formed at the tip portion. As shown in FIG. 4, the lifting lever 73 is mounted on the unit mounting base 90 and is disposed so as to be movable in the arrow B-B ′ direction. That is, the slide bearings 84 and 84 are disposed on the slide bearing rails 82 and 82 on the unit mounting base 90, and are mounted so as to be movable in the arrow B-B 'direction (vertical direction). Therefore, the lifting lever 73 can be moved in the direction of arrow B or arrow B ′ by driving the lower lift cylinder 86.

  Further, the lifting lever 73 can be swung in the direction of the arrow C-C ′ by driving the lifting and sliding cylinder 88. Therefore, as shown by the two-dot chain line at the position swung in the direction of the arrow C ′ in FIG. 4, the lifting lever 73 placed at the standby position far away from the walking beam 70 is moved to the sliding cylinder 86 by the arrow. By projecting in the direction B, the tip of the lifting lever 73 can be swung in the direction of arrow C, and the tip of the lifting lever 73 can be placed in the recess 77 of the walking beam 70.

  In this way, when the lifting cylinder 73 is projected again after the tip of the lifting lever 73 is placed in the recess 77 of the walking beam 70, only the lifting lever 73 is placed below the deposited metal plate 28. It can be lifted up as it is.

  In this way, after the deposited metal plate 28 is lifted from the walking beam 70, that is, after the deposited metal plate having a three-layer structure is lifted from the walking beam 70, only the walking beam 70 is shown in FIG. If moved in the direction of arrow A, the walking beam 70 can be returned to the initial position.

  Therefore, after returning the walking beam 70 to the initial position and then receiving a new deposited metal plate 28 on the receiving stage 72, continuous operation can be performed.

  In the above-described embodiment, the configuration in which the two lifting levers 73 are simultaneously driven by one sliding cylinder 86 is shown. However, the configuration in which the one lifting lever 73 is driven separately may be used.

  In this way, if the left and right lifting levers 73 are driven separately, the desired lifting operation can be performed without interfering with the conveyor chain, regardless of the arrangement of two adjacent conveyors. It can be performed.

  In the present embodiment, the transport apparatus for the deposited metal plate that simultaneously lifts the two lifting levers 73 and 73 by one sliding cylinder 86 is used in a place other than the second stage 56 that performs stripping (peeling). ing.

  On the other hand, in the 2nd stage 56 which peels off (peeling), the conveying apparatus which drives the lift levers 73 and 73 separately is used.

  As described above, according to the present embodiment, since the structure does not use a chain conveyor, the generation of noise is small, and the problem caused by the elongation of the chain conveyor does not occur.

  Further, the walking beam 70 and the lifting lever 73 are inexpensive because they have a simple structure.

  Further, for example, even if the deposited copper plate 28 is completely peeled from the stainless steel plate 22a in the peeling process, the copper plate 28 can be lifted from below with the stainless steel plate 22a without dropping.

  Furthermore, in the said Example, although the copper plate was illustrated as a deposit metal, a deposit metal is not limited to copper, Even if it is zinc etc., it can apply favorably.
