DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for packing the lead plates of a lead storage battery and an alkaline storage battery with a separator.

[0002]

2. Description of the Related Art The conventional packaging of electrode plates is disclosed in, for example,
As disclosed in Japanese Patent Application Laid-Open No. 10099, an electrode plate is placed on a protruding plate and moved in the horizontal direction, passes through a drive belt while folding a separator supplied in a vertical direction into two, and the both sides of the drive belt In this method, both sides of the separator are pressed by a hot plate disposed in the portion to perform heat welding, and at the same time, the protruding plate is retracted, and the heat-welded electrode plate is sent to the next step by a drive belt.

[0003]

According to the method described in the prior art, when an electrode plate wrapped with a separator is supplied to a position for heat welding of a drive belt, the electrode plate and the separator are particularly shifted from side to side. In order to achieve this, it is necessary to make the heat welding position of the separator sufficiently wider than both sides of the electrode plate. Therefore, there is a problem that the width of the electrode plate in the package must be reduced in order to insert the package electrode into a battery case having a predetermined width.

The present invention has been made in view of the above problems, and has as its object to provide an electrode plate for a storage battery capable of increasing the width of an electrode plate packaged in a separator having a predetermined width. It is to provide a packaging method.

[0005]

In order to achieve the above object, the method of the present invention comprises a pair of upper and lower fixed plates 5a, 5b which are narrower than the width of the electrode plate 1, and a push plate between the fixed plates 5a, 5b. The electrode plate 1 sandwiched between the two folded separators 2 is inserted into a jig 4 in which the pressing plate 8 presses the one fixed plate 5b, and then both sides of the electrode plate 1 The protruding separator 2 is welded. Then, when inserting the electrode plate 1 into the jig 4,
It is preferable that the electrode plate 1 is advanced while holding both sides of the electrode plate 1 so as to push the center of the separator 2 and inserted into the jig 4.

[0006]

[Operation] When the electrode plate sandwiched by the separator is inserted between the holding plate and the fixed plate pressed by the holding plate, the separator and the electrode plate are inserted in a state of being pressed against each other. It is accommodated in the jig without deviation.
Furthermore, when the both sides of the electrode plate are gripped, the electrode plate does not touch right and left, and the separator and the electrode plate do not shift.

[0007]

An embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a separator 2 folded in two with an electrode plate 1 interposed therebetween, and FIG. 2 shows a packaged electrode plate 3 in which both side portions 2a and 2b of the separator 2 are sealed. 3 and 4 are a plan view and a side view, respectively, of a jig 4 holding a separator 2 sandwiching the electrode plate 1. The jig 4 includes screws 6 on one side 5a of a pair of upper and lower fixing plates 5a, 5b. And a pressing plate 8 which is pressed against the other fixed plate 5b by a plate spring 7 fixed by the above. FIG. 5 shows a pair of upper and lower separator guides 9 a and 9 b facing the jig 4 and a pair of clampers 10 a and 10
It is a perspective view which shows b. FIG. 6 is a side view showing a state where the separator 2 is being inserted into the jig 4 with the electrode plate 1 interposed therebetween. FIG. 7 is a schematic plan view showing the entire process of one embodiment using the method of the present invention. The jig 4 is fixed to a rotary table 11 and includes a work supply station 12, a seal station 13, and a product removal station 14.

Next, the method of the present invention having the above-described configuration will be described. First, at the work supply station 12,
Both sides of the electrode plate 1 are gripped by a pair of clampers 10a and 10b, and the center portion of the separator 2 of a predetermined length supplied and guided by the separator guides 9a and 9b is advanced while being pressed against the end surface of the electrode plate. Jig 4
Between the pressing plate 8 and the fixing plate 5b. The electrode plate 1 sandwiched between the separators 2 is fixed to the jig 4 by a leaf spring 7.
And the clampers 10a and 10b are retreated. Next, the rotary table 11 is rotated to move the jig 4 holding the work to the sealing station 13, and the separators 2 protruding from both side portions of the electrode plate 1 are welded and sealed. Then, the rotating table 11 is rotated to move to the product take-out station 14, where the packaged electrode plate 3 is taken out from the jig 4.

[0009]

Since the present invention is configured as described above, the following effects can be obtained. (1) According to the method of claim 1, when the separator and the electrode plate are inserted into the jig, the separator and the electrode plate are pressed by the pressing plate. Can be made just before both sides of the board. (2) According to the method of the second aspect, it is possible to prevent the electrode plate from shifting right and left before inserting the electrode plate into the jig, and it is possible to more reliably set the welding position of the separator immediately before both sides of the electrode plate. . (3) As a result of the above (1) and (2), when housed in a battery case having a predetermined width, the electrode plate width can be made wider than before, and the battery capacity can be increased. (4) Since the respective steps of work supply, welding, and product removal can be separated, high-speed and stable full automation can be performed.
