Description

[Detailed Description of the Invention] (Industrial Application Field) This invention stores the cross beams extracted from the electrolytic cathode and arranged in a desired number in a row on a movable shelf, and then automatically This relates to a device that feeds each cathode one by one to a cathode finishing machine.

(Prior art) Conventionally, for example, in electrolytic refining of copper, cross beams are pulled out one by one or in groups from a cathode that has finished electrolysis, the beams are temporarily stored in a container, etc., and cathode finishing is performed as necessary. The material is transported to a machine, the ribbon and beam are attached to the seed plate, and the material is sent to the electrolysis process again.

(Problems to be Solved by the Invention) In this way, it is not only hard work to load long and heavy metal cross beams into a container, or to take them out one by one and feed them to a cathode finishing machine. During this time, the cross beam may be deformed,
There were problems such as damage to the surface, which adversely affected the electrolytic process. There were also other problems, such as the need for a transporter and a wide space to handle the containers.

In order to solve these problems, the present applicant has developed a cross beam for electrolysis that can automatically align the desired number of cross beams sent from the process of extracting the cross beams from the cathode that has finished electrolysis. A carry-in alignment device was proposed in Japanese Patent Application No. 190388/1988 (Japanese Patent Application No. 69612/1983).

However, the processing capacity and operating conditions of the process of extracting the cross beam from the cathode and the cathode finishing machine do not always match. Unless there is a device that can store a certain amount of material and take it out as required by the cathode finishing machine, the above problems cannot be completely solved. The object of the present invention is to provide a storage/unloading device for cross beams for electrolysis which solves the above-mentioned problems.

(Means for Solving the Problems) A device for stocking and unloading cross beams for electrolysis according to the present invention is arranged on a forming conveyor on which a desired number of cross beams for electrolysis are placed in a line with both ends aligned. a transfer carriage that supports the electrolytic cross beam from below the formation conveyor and moves it upwardly; a device that receives the electrolytic cross beam transferred by the transfer carriage and maintains a constant level in the horizontal direction; A carry-in conveyor that transports pitch by pitch; a movable conveyor provided in multiple stages in the vertical direction that moves vertically at regular pitches across both sides of the carry-in conveyor and detaches the electrolytic cross beam upward from both sides of the carry-in conveyor; a pull pusher that reciprocates between and outside of the movable shelf at a position different from the connection point of the movable shelf with the carry-in conveyor; and an electrolyte pulled out from the movable shelf by the pull pusher. and a carrying-out device on which the cross-beam for electrolysis is placed by a holding hook that moves downward after receiving the cross-beam for electrolysis.

(Function) Since the present invention is configured as described above, the cross beams aligned in a line with both ends aligned are carried into a plurality of movable shelves that are movable vertically while supporting both ends horizontally. Once stored, the stored cross beams can be automatically pulled out horizontally one stage at a time as needed, and then transported to the next process.

(Embodiment) FIG. 1 is a perspective view of the entire structure of an embodiment of the stocking and unloading device of the present invention, FIG. 2 a is a front view of the unloading device, and h is a side view thereof. As shown in the figure, the cross beams 16 that have been sent one by one from the previous process are arranged on the forming conveyor 1 with both ends aligned and the desired number of cross beams, for example 40, are arranged in a line and transferred to a conveyor on a movable shelf (described later). It is then brought in. This conveyance machine consists of a transfer cart 2 and an input conveyor 3, and the cross beam 16 on the forming conveyor 1 is lifted above the forming conveyor 1 by the rise of the cart lifting cylinder 14 of the transferring cart 2, and is separated from the forming conveyor. Check and stop with limit switch LS1. The transfer trolley 2 moves forward with the cross beam 16 lifted, and after checking and stopping with the limit switch LS4, the trolley lift hydraulic cylinder 14 descends and lifts the cross beam 16.
is placed on carry-in conveyor 3. The truck lifting hydraulic cylinder 14 continues to descend, and the limit switch is activated.
After checking and stopping with LS2, move backwards and set the limit switch.
Check and stop with LS3. Then, it waits until the cross beam 16 is carried into the formation conveyor 1.
The cross beam 16 placed on the carry-in conveyor 3 and received is detected and confirmed by the photoelectric switch PHSW1, and then transferred one pitch to the carry-in conveyor 3.
1 pitch is confirmed to stop the attachment 3a of the conveyor 3 by the limit switch LS5. The carry-in conveyor 3 repeats one pitch operation and finally carries the cross beam 16 to the next movable shelf. In this case, the carry-in conveyor 3 can also move continuously from the first pitch to the final pitch without stopping.

Next, the movable shelf is made up of up and down elevators 4 and 7 having a plurality of shelves, and the cross beam 16 carried into the up elevator 4 arranged to sandwich both sides of the carry-in conveyor 3 is connected to a photoelectric switch.
Confirmed by PHSW2, and also confirmed by photoelectric switch that there is no cross beam at the top of up elevator 4.
After checking with PHSW3, the up elevator 4 is operated in one pitch to separate from the carry-in conveyor 3 and carry it upward. The one-pitch operation of the up elevator 4 is stopped at a fixed position after the attachment 4a attached to the up elevator 4 is detected and confirmed by the limit switch LS7.
The up elevator 4 can operate continuously for one pitch depending on the state of the cross beam 16 (the number of blank stages) contained in the elevator.

Cross beam 1 to the top of up elevator 4
6 is carried, the transfer pusher 5 moves forward after confirming with the photoelectric switch PHSW3 and confirming with the photoelectric switch PHSW4 that there is no cross beam 16 at the top of the down elevator 7. As the attachment 5a attached to the transfer pusher 5 moves forward, the cross beam 16 passes through the transfer guide 6 and is transferred into the down elevator 7. After confirming the detection of the limit switch LS9, the transfer pusher 5 stops moving forward and moves backward. . Retreating is stopped after detection is confirmed by limit switch LS6, and the vehicle waits at the fixed position until the next cross beam 16 rises.

The cross beam carried to the top of the down elevator 7 is lowered one pitch after confirming with the photoelectric switch PHSW4 and confirming with the photoelectric switch PHSW5 that there is no cross beam at the bottom of the down elevator 7. One-pitch descent is stopped after detecting and confirming the attachment 7a attached to the down elevator 7 with the limit switch LS8. Also, the descent of the down elevator 7 depends on the state of the cross beam 16 in the elevator (number of blank stages).
One pitch continuous operation is possible. When the cross beam 16 is lowered to the lowest level by the descending operation of the descending elevator 7, the cross beam 16 is confirmed by the photoelectric switch PHSW5 and the limit switch LS8 is activated.
Upon confirmation of this, the down elevator 7 stops at the fixed position, and in this way the cross beam 16 is stored on the movable shelf.

Next, when carrying out the stored cross beams 16 to the next process, operate the downward elevator 7 of the movable shelf, and when the cross beams 16 arrive at the lowest stage, the next carrying out device will move the cross beams 16 from the movable shelf to the next stage. They are taken out one by one and detected one by one for the next process. This unloading device is composed of a pull pusher 8 that reciprocates between and outside the movable shelves at a position different from the point where the movable shelves connect with the loading conveyor, and an unloading conveyor 9.
As shown in the figure, first, the pull pusher 8 moves forward after detecting and confirming that there is no cross beam 16 in the deposit hook 17 using the photoelectric switch PHSW7. When the limit switch LS10 detects the detection, the pull pusher 8 stops moving forward, and the pull attacher 8a
Then, the cross beam 16 in the down elevator 7 is moved backward while being pulled in, and the cross beam 16 is transferred from the down elevator 7 to the deposit hook 17 through the transfer guide 15 (see FIG. 1). When the pull pusher 8 moves backward, it stops and waits at a fixed position after confirming the detection of the limit switch LS8.

Cross beam 16 moved into storage hook 17
Cross beam 16 by photoelectric switch PHSW7
After the photoelectric switch PHSW8 detects and confirms that there is no cross beam 16 above the carry-out conveyor 9, the lifting hydraulic cylinder 13 descends.

The cross beam 16 is placed on the carry-out conveyor 9 by the lowering of the lifting hydraulic cylinder 13, and the lowering is stopped when the limit switch LS16 is confirmed. After stopping, the hook opening/closing cylinder 12 returns (retracts) and the deposit hook 17 opens. The hook opening/closing cylinder 12 stops upon detection confirmation of the limit switch LS18, and the opening of the deposit hook 17 also stops. Then, as the lift hydraulic cylinder 13 rises, the depositing platform hook 17 also rises, and after stopping upon detection confirmation of the limit switch LS15,
The deposit hook 17 is closed by the push-out of the hook opening/closing cylinder 12, and stops after the detection of the limit switch LS17 is confirmed.

The cross beam 16 that has been lowered onto the carry-out conveyor 9 (see Fig. 1) is carried in the direction of the transfer machine 11, and after the detection of the limit switches LS12R and L is confirmed, the cross beam 16 is stopped, and the transfer machine 11 is operated one pitch ( (turn once with limit switch LS14), one end cross beam 16 is supported by a pair of arms 11a, 11b, and placed on top of feed roller 10. The cross beam 16 on the feed roller 10 is a photoelectric switch.
After the detection is confirmed by PHSW6, the feed roller 10 rotates to send it to the next process. At that time, the unloading conveyor 9 is started and the next cross beam is carried.
When LS12R and L are detected, the unloading conveyor will stop. By repeating the above operations, the desired number of stored cross beams are carried out one by one to the next process. Note that M in the figure indicates a motor.

In addition, in the above implementation, the number of beams in one stage is
Although 40 beams were used, the number of beams and the number of movable shelves can be selected by taking into consideration the amount of storage required for the previous and subsequent work processes, the factory layout, space, etc. For example, one electrolytic tank is set up in one stage, and the storage capacity for two cathode finishing processes is stored. Of the up and down elevators 4 and 7, it is also possible to use only the up elevator 4. In that case, the transfer pusher 5 becomes unnecessary. Also, the elevators 4 and 7 do not have to be reciprocating, but the height is smaller if they are reciprocating.
Moreover, there is an advantage that the height difference between carrying out and carrying in is small.
In addition, when carrying it into the elevator 4, it is necessary to put it in the lowest step. When transporting items, take them out from the bottom of the rear if they are going both ways, and from the top if they are only going out. Further, the attachment 5a of the transfer pusher 5 is fixed, but the attachment 8a of the pulling pusher 8 is a ratchet so that it falls down along the beam 16 when moving forward and pulls the beam 16 when moving backward.

(Effects of the Invention) As described in detail above, according to the present invention, a desired number of cross beams that are conveyed and aligned one by one are stored, and the stored beams are further carried out and supplied to the next process. Since it can be done fully automatically, the following effects can be obtained.

(1) Since no workers are required, it not only reduces man-hours, but also has great effects in terms of safety and health.

(2) Since deformation of the cross beam and damage to the surface can be prevented, the electrolytic process will not be adversely affected.

(3) Since the equipment is compact, it requires less space and provides greater flexibility in factory layout.

(4) By combining this device with other equipment in the electrolytic equipment, such as cathode cleaning equipment, cross beam extraction equipment, cross beam loading and alignment equipment, cathode finishing machine, etc., it is possible to automate the entire equipment, saving man-hours. Remarkable results can be achieved in improving the quality of products and improving safety and health.
