Description

[Detailed description of the invention] (Industrial application field) This invention uses a group of cathode seed plates, used for example in electrolytic refining, arranged in a predetermined number at a predetermined pitch.
This is a device that automatically carries the cathode into an electrolytic factory in a continuous manner, and particularly relates to a device that transfers the cathode to a carrying machine in the right angle direction without changing the direction of the cathode surface.

(Prior Art) For example, when electrolytically refining copper, a handle is fixed to the upper part of a thin copper plate, a seed plate with a beam inserted through it is used as a cathode, and the cathode is inserted into an electrolytic bath together with an anode for electrodeposition. This cathode seed plate is placed at the specified pitch.
It was necessary to transport a predetermined number of cathodes, for example half a cell, into an electrolytic factory so that the cathode surfaces of the cathode groups were aligned in parallel with the cathode surfaces in the electrolytic cell.
Therefore, depending on the layout of the factory, it was necessary to use a cathode finishing machine to transfer the cathode with the beam attached to a carrying machine in the right angle direction, but since there is currently no suitable equipment, a hoist crane or the like is used. Workers were transferring cathodes one by one.

(Problems to be solved by the invention) However, the above configuration has a problem of low productivity. Therefore, this invention provides a transfer device that solves the problems of the prior art.

(Means for Solving the Problems) In order to solve the above-mentioned problems, this invention provides an apparatus for transferring a group of cathodes arranged at a predetermined pitch to a carrying machine in a perpendicular direction without changing the direction of the cathode surfaces. , a gripping mechanism that detects a desired number of cathodes, suspends the group of cathodes at a time, and can move vertically up and down along a guide post; and a movement mechanism that can move this gripping mechanism in horizontal X and Y directions; The mechanism for detecting the empty position of the carry-in machine is controlled respectively to automatically transfer the cathode group to a desired position of the carry-in machine which is independently operating.

(Function) The cathode loading machine is installed in advance to be directly below the crane in the electrolytic plant, and when a group of cathodes is lifted by the crane, it independently operates, moves forward a predetermined distance, and then stops repeatedly. On the other hand, the cathodes are finished by a cathode finishing machine, aligned at a predetermined pitch by a cathode aligning machine, and then transported. Therefore, the gripping mechanism is placed on standby at a position slightly lower than the level of the cathode alignment machine, and the gripping mechanism that detects when a predetermined number of cathodes have been sent out operates to grip a group of cathodes and rise vertically. Next, the gripping mechanism is moved by the moving mechanism in the horizontally orthogonal X and Y directions to align with the center of the loading machine in the traveling direction. When the empty position is detected by the empty position detection mechanism in the carry-in machine, the gripping mechanism is lowered and the group of cathodes is loaded into the empty position of the carry-in machine. Naturally, all of these operations can be controlled by a phototube switch, a limit switch, etc., and in this way, the cathode surface can be automatically moved to a right-angled loading machine without changing its orientation. Therefore, the above-mentioned problem can be eliminated.

(Embodiment) FIG. 1 is a schematic perspective view showing an embodiment of this device. As shown in the figure, the cathode gripping mechanism A and the X, Y
This device is composed of a moving machine B that moves the cathode in the direction, and an empty position detection mechanism C of the cathode carrying machine.

The cathode gripping mechanism A is disposed on the cathode aligning machine 1, and grips both ends of the beam 15 of the cathode group arranged in a desired number at a predetermined pitch, thereby suspending the cathode group. A hook 2 is pivotally supported by a main body 4 so as to be openable and closable by an electric cylinder 3, as shown in FIG. Furthermore, photoelectric switches PS1 and PS2 are separately fixed to the tip of the main body 4 to detect the transferred cathode 16. Further, a rectangular parallelepiped post 5 is vertically fixed to the upper surface of the main body 4, and a transverse carriage 7 has a guide 6 that can be loosely fitted inside the post 5 and is disposed directly above the post 5.
is fixed to the bottom surface of. A wire 8 attached to a foil pivotally supported on both opposing outer surfaces of the post 5 is wound up by a drum of an elevator 9, so that the main body 4 can be vertically raised and lowered along the guide 6.

A traversing truck 7 is suspended on the moving mechanism B by a frame 10 so as to be movable in the horizontal X direction by driving wheels 7b with a motor 7a. Further, by driving the wheels 10b with the motor 10a in the Y direction perpendicular to the traversing truck 7, it is possible to run on a pair of rails 11. Limit switches LS11 to LS16 are fixed to predetermined positions on the frame 10, and limit switches LS7 to LS10 are also fixed to predetermined positions on the side of the rail 11.

The fixed position detection mechanism C is located on both outer sides near the rear end of a pair of link chains 12a and 12b of the cathode loading machine 12, which is arranged perpendicularly to the cathode alignment machine 1.
Two pairs of photoelectric switches PS3 and PS4 are provided in the direction perpendicular to the link chains 12a and 12b, and the distance between them is slightly wider than the width of the cathode plate. In addition, the cathode carrying machine 12 is provided with link chains 1 at intervals slightly smaller than the length of the beam 15.
A beam receiver 13 is attached at right angles to 2a and 12b. Note that the beam receiver 13 may be provided with recesses at a predetermined pitch. In addition, electric cylinder 3,
The motors 7a, 9a, and 10a all have a rotational speed of 2
It is variable in stages, with the first stage photoelectric switch or limit switch slowing down the rotation speed, and the second stage switch stopping it.

The cathode alignment machine 1 consists of a pair of horizontal bars 1a that suspend both ends of a beam 15, and a movable plate 1b with recesses provided at predetermined intervals on its upper surface, which are attached to an eccentric shaft off the central axis of a drive wheel 1c. Cage, foil 1c
When the cathode 16 is raised by the rotation of the moving plate 1b, the beam 15 is suspended in the recessed part of the moving plate 1b and moved forward, and when it descends, it is supported by the bar 1a so that the cathode 16 is advanced little by little at a predetermined pitch.

The operation of the apparatus configured as described above will be explained next.

First, when a group of cathodes is hoisted by a crane from a cathode carrying machine 12 installed directly below the crane of the electrolytic factory, the carrying machine 12 repeatedly moves forward a predetermined distance and then stops. On the other hand, the cathode aligning machine 1 transports cathodes 16 that have been finished by a cathode finishing machine (not shown) while aligning them at a predetermined pitch. Further, the cathode gripping mechanism A of this apparatus closes the hook 2 and is on standby at a position slightly lower than the level of the cathode alignment machine 1. The cathode 16 is transported and the photoelectric switch PS1
However, when the tip of the foil 1c is detected, the foil 1c decelerates and is stopped by the photoelectric switch PS2. Then, the motor 9a of the elevator 9 is started and the main body 4 is pulled up vertically. When the limit switch LS5 is activated, the motor 9a is decelerated and the limit switch LS is activated.
At 6, the rise stops. Next, the motor 10a is started, and the gantry 10 starts moving to the right in FIG. 1, decelerates when the limit switch LS9 is activated, and stops when the limit switch LS10 is activated. At this time, the center of the main body 4 and the center line of the carrying machine 12 in the advancing direction are aligned.

Next, the photoelectric switch PS3 of the fixed position detection mechanism C,
An empty position inside the loading machine 12 is detected by PS4,
If the photoelectric switch PS4 at the cathode loading position B in the figure detects the empty position, the motor 7 of the traversing truck 7
a starts, travels to the left in the diagram, decelerates at the limit switch LS13 position, and sets the limit switch LS.
Stops at 14. Then, the motor 9a reverses, lowers the main body 4, loads it into the cathode loading position RO of the cathode loading machine 12, and switches the limit switch LS18.
to decelerate and stop by limit switch LS17.
Since the beam 15 has been suspended on the beam receiver 13 up to this point, the starting cylinder 3 is activated and the hook 2 is fully opened (up to the photoelectric switch PS1).

If cathode charging position A in the figure is empty,
The traversing truck 7 travels to the limit switch PS16, and thereafter operates in the same manner. After charging, the device returns to its initial standby position by performing the reverse operation. From then on,
By repeating similar operations, the cathode group can be automatically transferred to the cathode loading machine 12. Moreover, if there is no empty position in the carrying machine 12 and the cathode 16 is transported to the tip of the cathode aligning machine 1,
The alignment machine 1 stops, but if a vacant position occurs, the transfer device automatically starts operating. Further, while this transfer device is in operation, the loading machine is not started.

(Effects of the Invention) As explained in detail above, according to the present invention, the aligned cathode group can be automatically transferred and transported to the next process without an operator, which is effective in saving labor. In addition, the position of the cathode finishing machine can be freely laid out with respect to the electrolytic plant, which has the effect of making effective use of a narrow site.
