DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seed plate for securing a copper plate for a copper electrolytic cathode ribbon to a seed plate so that it can maintain verticality when mounted on the seed plate, and also can secure compaction that can increase the loading capacity of a container. The present invention relates to a method for pressing a copper plate formed by cutting.

[0002]

2. Description of the Related Art Conventionally, a copper plate 1 for a copper electrolytic cathode ribbon.
As shown in FIG. 2, the thickness is 0.7 to 1.0 mm electrodeposited for one day,
It is made by cutting a seed plate 2 of about 1 mx 1 m. Then, the copper plate 1 is put into a chute of an automatic cathode finishing machine (not shown) and is bent and attached to the upper end portion of the cathode seed plate 3 so that the seed plate 3, the cross bar 4, and the copper plate (ribbon) 1 are separated as shown in FIG. The cathode 5 is assembled.

[0003]

By the way, the copper plate 1 cut from the conventional seed plate 2 has a perpendicularity (that is, the copper plate 1 has no inclination with respect to the vertical surface 7 when the copper plate 1 stands upright on the horizontal surface 6). Since it is bad and is often bent as shown in FIG. 4, the chute 8 of the cathode finisher as shown in FIG.
Troubles occurred in the middle of the game, causing the jamming without falling to the predetermined drop position. If a trouble occurs in the cathode finishing machine, the electrode replacement operation in the electrolytic factory must be stopped. Even if not caught, the copper plate 1 may be bent by being dropped and attached to the seed plate 3 as shown in FIG. In this case, the lower portion of the cathode 5 is bent, and when the cathode is attached to the electrolytic cell, the verticality of the cathode 5 is deteriorated, and the amount of correction work at the time of replacing the cathode is increased.

Accordingly, an object of the present invention is to provide a pressing method which solves the above-mentioned problems of the prior art, improves the perpendicularity of a copper plate for ribbon, and reduces troubles in a cathode finishing machine in a later step. And

[0005]

In order to achieve the above object, according to the first aspect of the present invention, a copper plate for a copper electrolytic cathode ribbon can be secured in verticality when it is attached to a seed plate, and an increase in the loading capacity of a container can be achieved. A method of pressing a copper sheet produced by cutting a seed sheet so as to ensure the consolidation to be made possible, wherein a first step of pressing the copper sheet almost simultaneously with the consolidation in a consolidation unit where a plurality of cut copper sheets are stacked and consolidated. And a second step of pressing substantially simultaneously with loading on a container further loaded on the container from the collecting section.

According to a second aspect of the present invention, in the first aspect, a lifter for receiving the copper plate is accommodated in the container,
Each time a press is made on a container, it descends by the height of the copper plate to be loaded.

[0007]

FIG. 1 is a front view of a most preferred embodiment of the present invention, in which a copper plate is loaded with its rough side facing down into a collecting portion for stacking and collecting a plurality of cut copper plates. Shows the state at the start of pressing. Reference numeral 11 denotes a consolidation unit, and 12 denotes a container. These are arranged adjacent to each other, and a plurality of stacked copper plates 1 on the consolidation unit 11 are extruded into the container 12 by an extrusion pusher 13 and can be loaded. . A lifter (not shown) that receives and places the copper plate 1 from the consolidating unit 11 is accommodated in the container 12, and is lowered by the height of the loaded copper plate 1 every time the container 12 is pressed. A press machine 15 is provided above the consolidation unit 11, and a press machine 16 is provided above the container 12.

The press machines 15 and 16 are located at an upper position in an initial state where the copper plate 1 after cutting has not been sent yet, and the copper plate 1 can be loaded on the consolidation unit 11 and the container 12. In such an initial state, when a plurality of cut copper sheets 1 are stacked on the consolidation unit 11 and loaded and consolidated, the press machine 15 is activated almost simultaneously to start pressing, and the consolidated copper plate 1 It is pressed on 11 (first step). When this press is completed, the push-out pusher 13 operates to push the pressed copper sheet 1 toward the container 12, whereby the copper sheet 1 is further loaded into the container 12 from above the consolidation unit 11 and loaded. Copper plate 1 in container 12
At the same time, the press machine 16 operates to start pressing almost simultaneously, and the copper plate 1 loaded in the container 12 is pressed a second time on the container 12 (second step). When this second press is completed, press machine 1
The operations of steps 5 and 16 are released, and the operation returns to the initial state, thereby completing one cycle of the press.

At the time of the second press in the next cycle, the lifter in the container 12 is lowered for each press to a position where the next copper plate 1 can be loaded into the container 12, so that the loading is not hindered. To In this way, the copper plate 1 that has been pressed for the first time on the consolidation unit 11 is twice on the container 12,
Pressed three times and formed into a material having consolidation and verticality.

[0010]

[Example] Verticality when pressing is performed twice, once each in the consolidation part 11 and the container 12, using the copper plate 1 of 380 mm x 100 mm, and the verticality when only one press is performed in the consolidation part 11 or the container 12 The following results were obtained by testing the properties.
In the consolidation unit 11, the ten copper sheets 1 and the container 12
Was performed on 450 copper plates 1. This verticality is obtained by fixing one side of the short side of the copper plate 1 to the horizontal surface 6 with a vice, and measuring the distance from the vertical surface 7 in this state, as shown in FIG. There are four measurement points A, B, C and D on the copper plate 1. Aggregation unit 11
Table 1 shows the average value (mm) of the verticality when only one press is performed and the standard deviation σ (sigma) indicating the degree of variation with respect to the whole, and Table 2 shows that when the container 12 is pressed only once.
Table 3 shows the result of pressing twice by the consolidating unit 11 and the container 12.

[0011]

[Table 1]

[0012]

[Table 2]

[0013]

[Table 3]

The standard deviation σ is the square root of the dispersion of the sample (copper plate 1) or the square root of the unbiased dispersion, and is obtained from the following equation.

[0015]

(Equation 1)

From these Tables 1 to 3, the aggregation unit 11 and the container
Consolidation unit 11 and container rather than press only with 12
The average value of the perpendicularity is smaller by about half or less when the press is performed twice at 12, indicating that the perpendicularity is more excellent. Also, the standard deviation value σ is as small as about half or less, and it can be seen that the variation is small.

In this embodiment, the press has been described only up to the second step, but it goes without saying that a third step may be further provided. Further, the apparatus in this embodiment includes an extrusion pusher 13, press machines 15, 16 and a lifter in the container 12, and is automatically controlled by, for example, a sequencer while being linked with a cutting device (not shown).

[0018]

According to the first and second aspects of the present invention, a first step of pressing a plurality of copper sheets after cutting and stacking a plurality of copper plates almost at the same time as consolidation, and further loading the containers from the consolidation section into a container Since it consists of a second step of pressing almost simultaneously with loading on a container, the perpendicularity of the copper plate for ribbon can be improved, and troubles in the cathode finishing machine in the post-process, which has conventionally occurred, can be reduced. . Further, the compactness of the copper plate is also improved, and the number of sheets loaded in the container can be increased. Furthermore, since the quality of the copper plate can be improved, there is an excellent effect that the variation in the verticality when the cathode is attached to the electrolytic cell is reduced, and the amount of correction work at the time of the cathode replacement work can be reduced.
