Abstract

PURPOSE:To secure the absorption of a seperator to a bent plate perfectly, by squeezing the separator to the bent plate at least at the cutting time of the separator. CONSTITUTION:After the final electrode plate a is superposed on a separator b of an electrode group side, a bent plate 1 is advanced in the direction to a table 3 while absorbing a separator c at the drawing out side by making the inner side of the bent plate 1 vacuum, and the bent plate 1 is erected vertical. Then an auxiliary bent plate 2 is dropped down and gives a tendency of bending to the said separator c. Furthermore, a cutter receiving plate 5 drops down, and squeezes the separator c to the bent plate 1 by its squeezing mechanism 7. Therefore, by this squeezing, the tip of the separator c is closely attached to the bent plate 1, and the absorption of the separator c to the bent plate 1 can be secured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an apparatus for alternately stacking electrode plates for storage batteries with separators interposed therebetween, and furthermore, the present invention relates to a method and an apparatus for stacking electrode plates for storage batteries alternately with separators interposed therebetween. This patent relates to an improvement of Application No. 60-38105.

Patent Application No. 1981-38105 states, ``After placing the cathode plate and the anode plate on the slide unit, a function is provided to fold the separator in a zigzag manner using a folding plate and an auxiliary folding piece. By reciprocating the slide unit q, the shade/VA+S provisional is alternately positioned in front of the pleated portion having the separator, and then the separator is vertically folded in the pleated portion, and
On a table with a function to maintain a constant stacking height, use Pink & Place to open one side of the separator and insert the negative and anode plates alternately and stack them. When a predetermined number of plates are stacked, the separators are stacked. A method for stacking electrode plates for a storage battery, characterized by cutting them. ” and “a pleat portion having a function of folding the separator in turns using a folding temporary and an auxiliary folding plate, a slide unit on which a cathode plate and an anode plate are placed and positioned in front of the pleat portion, and the pleat portion The separator is equipped with a big-and-place for alternately inserting the negative and anode plates into one opening of the separator folded in a zigzag manner, a table having a function of keeping the stacking height constant, and a cutter for cutting the separator. ``A device for stacking electrode plates for a storage battery, which is characterized in that it has the following structure.''

In addition, in the embodiment shown in Japanese Patent Application No. 6F)-38105, in order to hold the tip of the separator rake on the feeding side after cutting, the separator is vacuum-adsorbed with a folding plate, and then the separator is attached to the folding plate of the separator. In order to improve the adhesion of the separator, tension was constantly applied to the separator toward the feeding side.

However, with this configuration, if the tension is too strong, the separator will fold unevenly, so it is not possible to apply a very strong tension. The drawback is that the separator is not fully adsorbed to the plate, making it impossible to hold the separator;b The present invention has been made in view of the above points, and is a storage battery that can completely adsorb the separator to the folded material. This paper proposes a method and device for stacking electrode plates.

The invention of this book box 1 is a method for stacking electrode plates for a storage battery, in which a cathode (
In a method of stacking electrode plates for storage batteries, in which the reverse and anode plates are alternately inserted and stacked one on top of the other until a predetermined number of plates have been stacked, the separators are vacuum-adsorbed to the folded plates and cut. The separator is pressed against the folding plate at the time of cutting.

Further, the invention in Bookcase 2 is a storage battery electrode plate stacking device, characterized by comprising a folding plate that vacuum-chucks the separator, and a separator pressing ifR that presses the separator against the folding plate at least at the time of cutting the separator. It is something.

1 serving■ The present invention will be explained below with reference to one embodiment thereof.

That is, the first, second, and third diagrams are schematic side views of main parts sequentially showing states near the cutting process of the separator in one embodiment of the present invention.

That is, in the drawings, 1 is a folded plate having a cavity inside, and a plurality of elongated holes communicating with the cavity are bored in the contact surface with the separator, and a nozzle for vacuum piping is arranged in series with the cavity; 2; is an auxiliary folding plate, 3 is a table, 4 is a cutter, 5 is a cutter holder, 6 is a cutter holder is a part of the cutter holder of plate 5, 7 is a cutter holder is a separate plate made of an elastic body placed on temporary 5, and is pressed. It is a mechanism.

Further, a is the final electrode plate among the predetermined number of plates, b and c are separators mainly formed of glass fibers with a fiber diameter of 1 μ or less, and b is particularly a separator on the pole group side that is folded into a meander as a pole group. C is a separator on the feeding side.

Next, this embodiment will be explained step by step. That is, in this embodiment (as shown in Japanese Patent Application No. 60-38105,
The plates are stacked one after another, and the final plate a) is a group of rabbits (
After being stacked on the pjj separator b, the folded tent 1 advances in the direction of the table 3 and stands up vertically while adsorbing the delivery side separator C by creating a vacuum inside. Next, the auxiliary folding plate 3 hangs down,
A crease is formed on the separate rake C on the feeding side. Subsequently, the plate 5 of the cutter receiver is lowered, and the separator pressing mechanism 7 presses the feed-out side separator against the folding plate 1. In other words, due to this imposition,
Feeding/jjQ Tip of separator C y:1; The part is in close contact with folding material 1, so it can be fed out reliably)j+(Separator C can be adsorbed to folding material 1 by GTe iJ. This state can be Shown in Figure 1.

Next, cutter 4 is cutter holder temporary 5 and cutter holder is part 6.
advance in the direction of , and cut between the pole group side separator b and the feeding side separator C.

This state is shown in FIG.

Next, the cutter 4 is moved backward, and the cutter receiver and the plate 5 are also returned to their normal positions. This state is shown in FIG.

Thereafter, the pole groups stacked to a predetermined number are taken out from the table 3, and a new pole group is manufactured one by one. Then, the first electrode plate is placed on the table 3, the folded plate 1 falls horizontally, and the pole group separators b are stacked, and at this time, the vacuum suction of the folded plate 1 to the pole group separator b is terminated. Subsequently, after the next electrode plate is stacked, the folding temporary 1 is pulled out. And later, a special 1986-38
As shown in No. 105, assembly of the pole groups is performed sequentially.

As described above, according to the present invention, it is possible to eliminate troubles caused by poor suction of the separator, and it is possible to improve the operating rate.

Further, the present invention can be applied to the manufacture of storage batteries using thick separators, and the range of application thereof can be expanded.

As mentioned above, the present invention has extremely great industrial value.
