Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for manufacturing a storage battery plate group.

The conventional method for making electrode plates for lead-acid batteries is as follows:
This was a manual process in which workers alternately stacked cathode plates, anode plates, and separators. Later, this process was automated, and a method was adopted in which a large number of cathode plates and anode plate separators were stacked together, separated one by one using a vacuum or a kicker, and alternately stacked on top of each other. However, two electrode plates are manufactured with the legs connected, and in this method,
A separate process was required to cut the two connected electrode plates, and the production capacity key device was limited to about 700 batteries per day.

By solving these problems, we piled up two electrode plates while connecting them, and transported them one by one without pulling them out.
As shown in Fig. 1 and Fig. 2, a block consisting of a cathode plate 1, a separator 2, an anode plate 3, and a separator 2 is made, and the legs are cut with a circular saw during transportation, and the cut and separated blocks are stacked to form the final product. A method has come to be adopted in which a cathode plate 1 is placed on a block as shown in FIGS. 3 and 4 to make two groups of electrode plates at once. Although this method was able to achieve high performance and compactness, it required cutting the electrode plate with a circular saw, and short-circuit failures often occurred due to mixing of cut layers within the group.

The present invention overcomes these problems of the prior art and requires a lot of man-hours. Production capacity is low. The present invention provides a method for manufacturing electrode plate groups that solves problems such as the mixing of cutting debris caused by cutting with a circular saw, maintains high production capacity, and eliminates the occurrence of short circuit defects.

That is, the present invention is to manufacture an electrode plate group by the method shown in FIGS. 5 and 6.

First, the cathode plates 1 and the anode plates 3, which are connected at their legs, are alternately supplied and placed on the conveyor 4. The supply is performed with the left and right sides of the cathode plate 1 and the anode plate 3 reversed, and the supply of the anode plate 3 is stopped once every predetermined number of sheets by electrical or mechanical means. 5 indicates a location on the conveyor 4 where the supply of anode plates is stopped.

Next, the separator 2 is supplied and placed on the cathode plate 1 and anode plate 3 that are conveyed by the conveyor 4. The supply of separators 2 is stopped twice every predetermined number of sheets. In other words, the anode plate supply stop point 5
The supply of the separator 2 to the cathode plate 1 located adjacent to the cathode plate 1 in front of the cathode plate 1 is stopped by electrical or mechanical means.

Before or after the separator is supplied, the cathode plate 1 and the anode plate 3 are introduced into a slitter while being conveyed, and are cut and separated at the feet. This cutting is
The foot of the electrode plate is sent into the gap between the blades or between the blade and the pedestal and is pressed down, so no cutting debris is generated.
The cathode plates 1 and anode plates 2 are cut and separated into two rows, and the cathode plates 1 and anode plates 2 with separators 2 placed thereon are stacked one after the other in each row, and the cathode plates to which no separator has been supplied are stacked to form one group. .

In the present invention, since the cutting is performed using a slitter, there is no risk of cutting debris getting into the electrode plate group, and since the electrode plate group is formed in two rows at the same time, productivity is good. Further, in the present invention, since the supply of anode plates is stopped once for each unit constituting one group of electrode plates, there is sufficient time to take out the configured electrode plate group.

FIGS. 7 and 8 show an example of a manufacturing apparatus for carrying out the present invention.

Reference numeral 6 denotes a cathode plate stock section, in which the cathode plates 1 are stacked with their ears suspended, and are fed onto the conveyor 4 one by one from the end surface. The anode plates are also supplied in the same manner from the anode plate stock section 7, and the cathode plates 1 and anode plates 3 are alternately supplied and placed on the conveyor 4 at the merging section 8. The supply of anode plates is stopped once every predetermined number of sheets, and the cathode plates 1 and anode plates 2 conveyed by the conveyor 4 are cut off by a slitter 9 to remove unnecessary portions of the ears, and at the same time, the legs are cut by a slitter 9'. and separated into two columns. A separator 2 is supplied onto the separated cathode plate 1 and anode plate 3, and a separator supply section 10 for the cathode plate and a separator supply section 10' for the anode plate are separately provided. Each supplies separators 2, and by stopping the supply once every predetermined number of sheets, the supply of separators to the anode plate supply stop point 5 and the cathode plate 1 located adjacent to this point is stopped. .

The cathode plates and anode plates to which the separators have been supplied in this way are dropped at the plate group stacking section 11 at the end of the conveyor 4 to form a predetermined plate group.

As described above, according to the present invention, an electrode plate group free from short-circuit defects can be manufactured with high efficiency, and its industrial value is extremely large.
