Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrodeposited metal plate stacking device for horizontally stacking a large number of electrodeposited metal plates obtained in electrolytic smelting of non-ferrous metals such as lead and copper.

Generally, in lead electrolytic smelting, a high-purity lead thin plate with a crossbar (beam), which is a conductive rod, on the top is used as the cathode plate, and crude lead is used as the anode. Lead, which is a target metal, is electrodeposited on the cathode plate using a lead solution as an electrolyte.

Also, in electrolytic smelting of copper, copper is deposited on the copper thin plate using a high-purity copper thin plate as a cathode plate, blister copper as an anode, and a sulfuric acid acidic copper sulfate solution as an electrolyte. In electrolytic smelting in which the target metal is used as a cathode plate, the electrodeposited metal plate obtained by depositing the target metal on the cathode plate is taken out of the electrolytic bath, transported, and charged into a melting furnace. The metal melted in the melting furnace is made into an ingot and transported to the next process, shipped, or stored in a warehouse. Since the deposited metal and the cathode plate are made of the same metal, there is no need to peel off the separated metal deposited on the cathode plate, and the electrodeposited metal plate is transported as is and charged into the melting furnace, but in this case, transportation To increase efficiency, many electrodeposited metal plates are transported in bulk. The electrodeposited metal plates taken out of the electrolytic cell are transported vertically suspended from the crossbar, but they are very heavy and must be turned horizontally and stacked to make it easier to transport them in bulk. Must be. However, since the electrodeposited metal plate is normally transported by supporting both ends of the cross spar and suspending it,
If this electrodeposited metal plate was simply laid down and its condition changed, the position of the electrodeposited metal plate would be lowered, and in order to stack a large number of them on a conveyor etc. installed on the floor, the electrodeposited metal plate would have to be raised again. Must be lifted into position. In this way, changing the state of the electrodeposited metal plate and then lifting it, or vice versa, increasing the number of steps and equipment, which is disadvantageous in terms of time and space, and is very inconvenient. It's the economy. Therefore, it is necessary to move the vertical electrodeposited metal plates to a horizontal state at a higher level and proceed with stacking them in a few steps. Also, the cross spar attached to the cathode plate must be removed before the electrodeposited metal plates are loaded into the melting furnace, but after stacking the electrodeposited metal plates horizontally, the cross spar should be removed. Since there is no need to hang the crossbars, it is convenient for later work to remove the crossbar when stacking electrodeposited metal plates horizontally. Furthermore, the horizontal electrodeposited metal plates can be stacked in large numbers on a table to be transported to the next process, or the easiest way to stack the electrodeposited metal plates on a table is to drop the electrodeposited metal plates and stack them. There is a way. However, the electrodeposited metal plates are dropped and stacked on a table that is stopped at a fixed position. In this case, the falling distance at the beginning of stacking is long, and the falling distance changes each time the stacking is done, so there is a risk that the stacking may not be successful or the cargo may be misaligned. In order to eliminate these drawbacks, the table should be positioned as close as possible to the position where the electrodeposited metal plate falls, and each time the electrodeposited metal plate is dropped, it should be lowered by about the thickness of the electrodeposited metal plate. Just do it. By doing this, the falling distance of the electrodeposited metal plates can be kept short and always constant, and the stacking of the electrodeposited metal plates on the table can be carried out reliably without fear of the load collapsing. become. As described above, the electrodeposited metal plate, which is supported at both ends of the cross spar and is transported in a vertically suspended state, is placed in a horizontal state at a high position, and the cross spar is electrodeposited in a horizontal (vine) state. The purpose is to shorten working time and equipment space, and to ensure reliable stacking of electrodeposited metal plates by pulling them out from metal plates, then dropping them a certain distance and stacking them in large numbers. The structure consists of a receiving part that supports the electrodeposited metal plate, and a support part that supports the electrodeposited metal plate during the daily transport process when the electrodeposited metal plate is transported by holding both ends of the cross spar and suspended vertically. A rotary table having a hook for hanging a cross spar of a protruding electrodeposited metal plate is provided so as to be rotatable around a horizontal axis perpendicular to the conveying direction of the electrodeposited metal plate, and the rotary table after the cross spar is hung on the hook. Rotate the electrodeposited metal plate to make it horizontal, and move the electrodeposited metal plate forward by holding the crossbar of the electrodeposited metal plate that is horizontal on the receiving part of the rotary table after rotation. A feeding device is provided in front of the rotary table, and supports both sides of the electrodeposited metal plate conveyed by the feeding device from below, and rotates downward to move the electrodeposited metal plate. A support plate to be dropped downward is connected to a rotary table after rotation and is provided in front, while an extrusion device for pushing out a crossper of an electrodeposited metal plate supported on the support plate is provided on the side of the support plate, and a pusher is provided on the side of the support plate. ``After the ROSPAR has been pushed out, the lifting table receives the electrodeposited metal plates that fall due to the rotation of the support plate, and lowers by a certain amount each time it is stacked, and always receives the electrodeposited metal plates at the same height. It is installed between the chains of a carry-out chain conveyor installed below, and after a predetermined number of electrodeposited metal plates are stacked, the elevating table descends and, on the way, the electroplated metal plates on the elevating table are transferred to the chain conveyor. It is characterized by the fact that

Further, a shock absorber mounting base 44 is fixed to both sides of the frame 29, and a rear shock absorber 45 is attached to the shock absorber mounting base 44 facing rearward.
When the rotary table 8 rotates to the position where the cross spar 6 is delivered, the rear shock absorber 45 hits the rear stopper 47 attached to the column frame 46, and the rotary table 8 is stopped.
The impact received by the person is alleviated. The angle at which the rotary table 8 can rotate is 90 degrees, and the piston rod 39 is rotated by the operation of the rotary table cylinder 38 from the position where the cross spar 6 is received by the hook 19 shown by the two-dot chain line in FIG. Until the rotary table 8 rotates 90 degrees due to the extension, the front shock absorber 41 hits the front stopper 43, and the receiving plate 30 of the rotary table 8 becomes horizontal as shown by the solid line in the drawing. It is. The support plate 4 of the drop device 48 is placed in front of the rotary table 8 at the same height as the surface of the support plate 30 when the rotary table 8 rotates and the support plate 30 becomes horizontal.
9 is provided above the support plate 49 and horizontally held by the rotary table 8. A feeding device 50 is provided for feeding the electrodeposited metal plate 1 with the cross spar 6 placed thereon onto the support plate 49.

The feeding device 50 is rotated in the rotated state; both ends of the cross par 6 are hooked by a feeding hook 51 that can move backward from the cross par 6 which is locked to the hook 19 of the table 8, and the electroplated metal plate is moved. 1 onto the support plate 49 of the dropping device 48.

(As shown in FIG. 2, FIG. 7 which is a partially enlarged view of the feeding device and dropping device in FIG. 2, and FIG. 8 which is an enlarged plan view of the feeding device, Two guide rods 5 are mounted on two horizontal frames 52 at the front and rear.
3 are supported in parallel in the front-rear direction, and a sliding body 54 is slidably fitted into these guide rods 53, and a piston rod of a feeding cylinder 56 installed on a cylinder support frame 55 is fitted into this sliding body 54. 57 are connected, and the sliding body 54 is guided by the guide rod 53 and moves back and forth as the piston rod 57 expands and contracts due to the operation of the cylinder 56.

Hook support plates 58 are attached to both lower ends of the sliding body 54, and the feeding hooks 51 are supported by these hook support plates 58, respectively. The feed hook 51 is rotatably supported by a hook support plate 58, and the hook support plate 58 is provided with a stopper 59, and the rear part of the feed hook 51 is in contact with this stopper 59. The feeding hook 51 rotates clockwise as shown in Figures 2 and 7. It is designed so that it can only be rotated in this direction. Therefore, the rotary table 8 rotates to the state shown in FIG. 7, and the sliding body 54 is moved backward by the operation of the feeding device cylinder 56, and the rear part of the feeding hook 51 is moved back during the retreat. Rotary table 8: , hook 19
Since the feeding hook 51 can rotate forward even if it hits the cross spar 6 which is locked on the cross spar 6, it can climb over the cross spar 6 and reach the feeding hook 51' shown by the two-dot chain line in FIG. It can be moved to the rear side of the cross par 6. When the feeding hook 51 goes to the rear side of the cross spar 6, the cylinder 56 is operated in the opposite direction to retract the piston rod 57, and the sliding body 54
As the feeding hook 51 moves forward, the feeding hook 51 moves toward the cross spar 6.
The electrodeposited metal plate 1 is caught on the sliding body 54 and is carried onto the support plate 49 of the dropping device 48 . Also 7th,
8 and 2, which is a 10-10 line direction arrow view.
As shown in FIG. 0, two sets of guide rollers 60 are provided on the upper surface of the sliding body 54, and are respectively attached to two parallel guide rail receivers 61 supported by the horizontal frame 52 of the frame body 32. The guide roller 60 comes into contact with the guide rail 62 that has been moved, and guides the movement of the sliding body 540. A dropping device 48 that drops the electrodeposited metal plate 1 sent by the sending device 50 downwards,
It consists of a rotation shaft 63 that is rotatably supported, and the support plates 49 and 7 that are attached to this rotation shaft 63 and on which the electrodeposited metal plate 1 is placed.

As shown in FIGS. 2 and 7 and FIG. 9, which is an enlarged plan view of the dropping device 48, the rotation shaft 63 and the support plate 49 are provided facing each other in parallel, and one end of the rotation shaft 63 is attached to the frame. It is supported by a bearing 65 attached to a column frame 64 of the body 32, and the other end is supported by a bearing 68 fixed to a base 67 on a support frame 66. Further, a cylinder 69 for a dropping device is installed on the base 67, and a piston rod 70 of this cylinder 69 has a rack connected to its tip by a connecting plate 71, a gear meshing with the rack, a shaft supporting the gear, and a gear hook. It is connected to the rotating shaft 63 via a gear group housed in the rotary shaft 72 . Therefore, the support plate 49 rotates together with the rotating shaft 63 due to the back and forth movement of the piston rod 70 due to the operation of the dropping device sill 69. Since the support plate 49 receives the electrodeposited metal plate 1 sent by the feeding device 50 and drops it downward, it is only necessary to rotate it downward by a certain angle. Therefore, there are stopper arms on both sides of the rotating shaft 63. 72, and the stopper arm 72 is fixed to the column frames 64 and 73, respectively.
The rotation shaft 63 rotates and the support plate 49 rotates only within a necessary range, that is, from the horizontal position to the downward direction until the support plate 49 becomes vertical. There is. The electrodeposited metal plate 1 carried by the feeding device 50 onto the support plate 49 of the dropping device 48 is dropped onto the lifting table 76 of the lifting device 75 below by rotation of the supporting plate 49. The cross spar 6 previously attached to the electrodeposited metal plate 1 is removed.

The cross spar 6 is removed by an extrusion device 77 shown in FIGS. 3 and 10. Extrusion device 77
The pusher head 8 is connected to the piston rod 79 of the extrusion cylinder 78 installed on the side of the dropping device 48 via a joint or the like.
0 is attached, and when the piston rod 79 is expanded by the operation of the cylinder 78, the pusher head 80 abuts against the end of the cross spar 6, and the cross spar 6 is pushed out from the electrodeposited metal plate 1. The electrodeposited metal plate 1 from which the crossbar 6 has been removed is dropped onto the lifting table 76 of the lifting device 75 located below by the rotation of the support plate 49. The lifting device 75 will be explained below.

Figures 2 and 10 and Figure 11, which is a longitudinal cross-sectional view of the lifting device 75.
As shown in the figure, the lifting device 75 moves within a bit 83 formed on the floor 20 between the chains 82 of a chain conveyor 81 for carrying out the electrodeposited metal plates 81 that transports a predetermined number of stacked electrodeposited metal plates 1 to the next process. The lifting table 76 for receiving and loading the electrodeposited metal plate 1 is attached to the tip of the piston rod 85 of the vertically supported lifting cylinder 84, and the lifting table 76 passes between the chains 82 by the operation of the cylinder 84. It is configured to go up and down.

The cylinder 84 is supported by a frame 87 horizontally attached to a column 86 fixed to the inner wall of the bit 83. Locking tools 88 are attached to both end surfaces of the lifting table 76, and the lifting table 7 is moved by the operation of the sill 84.
When the lifting table 6 is raised, the locking tool 88 comes into contact with a stopper 90 attached to the vertical frame 89 of the frame body 32, and the lifting table 76 is stopped at the uppermost position. The elevating table 76 receives the first electrodeposited metal plate 1 at this uppermost position, and each time it receives the electrodeposited metal plate 1, it lowers by a certain amount to receive the electrodeposited metal plate 1 at the same position. This operation, that is, to bring the surface of the electrodeposited metal plate 1 on the lifting table 76, which is the receiving surface of the next electrodeposited metal plate 1, to a fixed position is carried out by detecting the position with an ultrasonic device. When a predetermined number of electrodeposited metal plates 1 are stacked on the lifting table 76, the lifting table 76 is lowered below the line of the chain conveyor 81 to remove the electrodeposited metal plates 1 on the lifting table 76. While the electroplated metal plate 1 is being transferred onto the chain conveyor 81 and transported to the next process, it is necessary to stop the electrodeposited metal plate 1 from falling. To stop the electrodeposited metal plate 1 from falling, since the thickness of the electrodeposited metal plate 1 is almost constant, the number of falling electrodeposited metal plates 1, that is, the number of rotations of the support plate 49, is counted, and this becomes the designated number of times. This is done by sending a time stop signal to the dropping device 48 and the like. As shown in FIG. 11, the inside of the lifting table 76 is filled with lead 91 to maintain its stability, and a vertical guide rod 93 with a guide surface 92 is provided below the lifting table 76. Two guide rods 93 are provided, and the rollers 96 provided on the mounts 94 and 95 installed on the pedestal 87 and the floor 20 are brought into contact with the guide surfaces 92 of these guide rods 93, and the rollers 96 are raised and lowered by the operation of the lift cylinder 84. table 7
6, the upper surface of the lifting table 76 is guided so that it can be moved while keeping it properly level.

The embodiments of the stacking device shown in the drawings have been explained for each device, but below we will explain the relationship between each device until horizontally stacking a large number of electrodeposited metal plates 1 that are conveyed in a vertically suspended state. I will explain it together.

The electrodeposited metal plate 1, whose direction is changed by the direction change device 7 and is suspended by the direction change device 7' in FIG. 3 while supporting both ends of the cross spar 6, rotates in the direction of the arrow in FIG. Both ends of the cross spar 6 are lifted from below and rotated by the receiving portions 18 of the receiving link 17 of the shifter 9.

The cross spar 6 of the electrodeposited metal plate 1 rotated by the shifter 9 is, as shown by the two-dot chain line in FIG.
It is hung over the hook 19 of the rotary table 8, which is waiting in the state shown by the two-dot chain line in the figure. When the crossbar 6 of the electrodeposited metal plate 1 is hooked onto the hook 19 of the rotary table 8, the rotary table cylinder 38 is actuated and the piston rod 39 is extended to move the rotary table 8 as shown by the solid line in FIGS. Then, the electrodeposited metal plate 1 is placed on the horizontal receiving portion 30. That is, the electrodeposited metal plate 1 changes from a vertically suspended state to a horizontal state at a high position. Next, the sliding body 54 moves rearward due to the extension of the piston rod 57 caused by the operation of the feeding sill 56 of the feeding device 50, and the feeding hook 51 supported by the sliding body 54 engages with the hook 19 of the rotary table 8. Cross over the stopped cross spar 6 and come to the rear side. The feeding hook 51 hits the cross par 6 during the retreat, but since the feeding hook 51 can rotate forward and upward, its movement is not hindered by the cross par 6. The sliding body 54 moves forward due to the shortening of the piston rod 57 due to the reverse operation of the feeding cylinder 56, and at the beginning of its movement, both ends of the cross spar 6 are caught by the feeding hook 51, and the electrodeposited metal plate on the receiving part 30 is hooked on the feeding hook 51. 1 is the drop device 48
is transported to a predetermined position on the support plate 49 of. Support stand 49
The crossbar 6 attached to the tip of the electroplated metal plate 1 carried above is moved to the pusher head by the elongation of the piston rod 79 by the operation of the extrusion cylinder 78 of the extrusion device 77 shown in FIGS. 3 and 10. It is extruded with impact through 80. When the cross spar 6 is removed, the support plate 49 rotates downward due to the operation of the drop device cylinder 70.
The electrodeposited metal plate 1 placed on the support plate 49 is dropped downward. Below the dropping device 48, an elevating table 76 of the elevating device 75, which has risen to the highest position, stands by, and the fallen electrodeposited metal plate 1 is received by this elevating table 76. When the electrodeposited metal plate 1 is placed on the lifting table 76, the lifting cylinder 84 is activated, and the lifting table 76 is moved so that the surface of the electrodeposited metal plate 1 thereon is at a predetermined position (corresponding to the uppermost position of the lifting table 76). Descend until you reach . Therefore, the next falling electrodeposited metal plate will be caught at the same position. When a predetermined number of electrical sign metal plates 1 are stacked on the elevating table 76, which receives the electroplated metal plates 1 falling one after another and descends each time it receives an electroplated metal plate 1, the dropping device 48 etc. stops, and the electroplating stops. The metal plate 1 will no longer fall. At the same time, the elevating table 76 loaded with a predetermined number of electrodeposited metal plates 1 is lowered to the bottom of the line of the chain conveyor 81 for carrying out by the operation of the elevating cylinder 84. Deposited metal plate 1 (hereinafter referred to as electrodeposited metal plate group I)
is transferred onto the chain conveyor 81 and transported to the next process by the chain conveyor 81. Electroplated metal plate group I is dropped by chain conveyor 81 to dropping device 4
8, the lifting table 76 rises again to the uppermost position where its locking tool 88 hits the stopper 90, and prevents the first electrodeposited metal plate from falling to form the next group of electrodeposited metal plates. wait. By repeating the above operations, a predetermined number of electrodeposited metal plates are sequentially stacked and transported to the next process as a group of electrodeposited metal plates.

As described above in detail with reference to the embodiments, the electrodeposited metal plate stacking device of the present invention allows the electrodeposited metal plates to be transported to a high position while being vertically suspended by holding the crossbar. The movement and change of state from vertical to horizontal are performed in one motion by rotating the rotary table, and a feeding device for moving the horizontal electrodeposited metal plate and a dropping device for dropping the electroplated metal plate are installed above and below. At the same time, the crossbar of the electrodeposited metal plates is removed when they are supported by the dropping device, and the electrodeposited metal plates that are dropped from the dropping device are always received at a substantially constant position and stacked in large numbers, thereby reducing the number of steps. This makes it possible to shorten the working time and reduce the space required for the apparatus, and also allows the electrodeposited metal plates to be stacked reliably without fear of the loads falling apart. Also, since the cross spar is removed during the stacking process, it is convenient for the work after stacking.
