Abstract

PURPOSE:To keep high production capacity and completely eliminate occurrence of short-circuit defect by constructing one group by stacking an anode plate having no supplied separator on the sequential stack of separated anode plates and cathode plates. CONSTITUTION:An anode plate 1 and a cathode plate 3 each of which is connected with two feet are mutually supplied on a conveyor 4. The anode plate 1 and the cathode plate 3 are supplied dissymmetrically, and supply of the cathode plate 3 is stopped electrically or mechanically once every the specified number of plates. A separator 2 is placed on the anode plate 1 and the cathode plate 3. Supply of the separator 2 is stopped twice every the specified number of plates. Before or after supply of the separator, the anode plate 1 and the cathode plate 3 are introduced to a slitter during conveyance to cut out their feet, the plates becomes two rows, and the anode plate 2 and the cathode plate 3 which the separator 2 is placed thereon are stacked in order in every row, then the anode plate with no separator placed is stacked to construct one group.

Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to an improvement in the manufacturing method of a storage battery electrode group.

Conventionally, the method of making electrode plates for lead-acid batteries is to use cathode plates,
This was a manual process in which workers alternately stacked five anode plates and separators.

Later, this operation 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 stacked in alternating numbers. However, bridge plates are manufactured with two plates connected at the feet, and this method requires a separate process to cut the two connected plates, and also requires a production capacity oyster machine. battery TO
The limit was about O pieces/day.

To solve these problems, the two electrode plates are piled up in a connected state, and the plates are pulled out and transported one by one, and the cathode plate 1, dragon pallet 2, Anode plate 3
, a method was adopted in which a block called separator 2 was made and the legs were cut with a circular saw during transportation 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 the mixing of cutting debris within the group.

The present invention differs from these conventional techniques in that it requires (1) more man-hours; ■Production capacity is low. ■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, in the present invention, an electrode plate group is manufactured by the method shown in FIGS. 5 and 6.

First, the cathode plates 1 and the anode plates 3, which are connected by their legs, are alternately supplied and placed on the conveyor 4. The supply is performed by reversing the right and left sides of the cathode plate 1 and the anode plate 3, 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 cathode plate 1 is conveyed by the conveyor 4.
, the separator 2 is supplied and placed on the anode plate 3. The supply of separators 2 is stopped twice every predetermined number of sheets. That is, the supply of the separator 2 to the anode plate supply stop point m 5 and the cathode plate l located adjacent thereto is stopped by electrical or mechanical means.

Before or after supplying the sehalator, the cathode plate 1, the anode plate 3. While being transported, they are each introduced into a slitter and cut and separated at the foot. This cutting involves sending the V section of the electrode plate into the gap between the blade and the blade or between the blade and the pedestal.
Cutting debris is generated. Cut and separate and form 2 rows,
The cathode plates 1 and anode plates 2 on which the separators 2 have been placed are fused and stacked in each row, and the cathode plates to which no separators have been supplied are stacked to form one group.

In the present invention, since the cutting is carried out using a slitter, there is no chance of cutting debris getting mixed into the electrode plate group, and since the electrode plate group is formed in two rows at the same time, productivity is improved.

Further, in the present invention, since the supply of anode plates is stopped once for each unit constituting one group of electrode plate groups, 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 strap part, and the cathode plates l are stacked with their ears suspended, and are fed onto the conveyor 4 one by one from the end face. The anode plates are also supplied in the same way from the cathode plate stock section 7, and at the merging section 8, the cathode plates 1 and anode plates 3 are alternately supplied and placed on the conveyor 4. The supply of Iζ anode plates is stopped once every predetermined number of sheets, and the cathode plates 1 are conveyed by the conveyor 4.
The cathode plate 2 is separated into two rows by having the unnecessary portions of the ears cut off by a slitter 9 and the legs cut off by a slitter 9'lζ. A separator 2 is supplied onto the separated cathode plate 1 and anode plate 3, respectively, and a separator supply section 10. Separator supply section 1 to the anode plate
0' is provided separately. Each is separator 2
By supplying separators and 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 plate and anode plate thus supplied with the Cζ separator are dropped at the plate group stacking section II at the end of the conveyor 4, and a predetermined plate group is formed. It is possible to manufacture defect-free electrode plates with high efficiency, and its collective value is extremely great.
