Abstract

PURPOSE:To stabilize a quality by supplying a plate with a separator provided with a fold by a fold habit cutter, repeating this action and cutting the separator on the piled up plates by a cut habit cutter. CONSTITUTION:A fold habit cutter 6 is lowered down to an upper surface of a receiving table 8 to give a peculiar fold to a predetermined position of a separator 2 and also fixing it by the cutter 6 and the receiving table 8, so that the separator 2 is prevented from being dislocated, to retract a fold plate 1. The plate 1 is 90 deg.C rotated with an axis 1a serving as the center, advanced in a direction of a plate group 4 and again 90 deg.C rotated. Simultaneously, while lowering down an elevator 3 by the thickness of a plate 10, a pusher 5 is lowered down and brought into contact with an upper surface of the plate 10 to hold it. By repeating this action, a predetermined number of sheets of the plates and the separator 2 are piled up to form the plate group. Next, a cut habit cutter 7 is lowered down to cut off the separator. In this way, even a small plate can be piled up without generating loading collapse.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for alternately stacking electrode plates for storage batteries with separators interposed therebetween, and an improvement in the apparatus.

0002

2. Description of the Related Art In a conventional method of stacking electrode plates for storage batteries, separators are folded in a serpentine manner using folding plates and auxiliary folding plates, as disclosed in, for example, Japanese Patent Application Laid-open No. 198575/1983. Met.

0003

[Problem to be solved by the invention] In the above conventional method,
Since the separator is folded using the folding plate and the auxiliary folding plate,
There were variations in the bending dimensions due to the tension caused by the tension roller and friction with the electrode plates during stacking. In addition, since the bent part did not bend completely 180 degrees and was rounded, unless constant force was applied from above the stacked electrode plates, the electrode plates would lift upwards and the electrode plates would not sit stably. . In particular, small electrode plates had the problem that they could not be stacked because the plates would collapse on the way.

The present invention has been made in view of the above-mentioned problems, and its object is to provide a method for stacking electrode plates for a storage battery, which allows even small electrode plates to be stacked by reliably bending separators at predetermined positions. and to provide the equipment.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the method of the present invention includes a first step of placing an electrode plate 10 on an elevator 3, and a crease cutter 6 to make a crease at a predetermined position. a second step of feeding the folded separator 2 onto the electrode plate 10 while folding it with a folding plate 1; a third step of placing the electrode plate 10 on the separator 2 bent on the electrode plate 10; A fourth step of stacking a predetermined number of electrode plates 10 by repeating the second step and third step, and a cutter 7
This method is characterized by comprising a fifth step of cutting the separator 2, which has been cut at a predetermined position, on the electrode plates 10 stacked in the fourth step.

The device of the present invention also includes a folding plate 1 that rotates around a shaft 1a provided on one side and moves back and forth to fold the separator 2 vertically, and a stack of polar plates. An elevator 3 that has the function of keeping the height of the top surface of the group 4 constant, and a pusher 5 that moves up and down above the elevator 3 and has the function of holding the electrode plate group 4 and cutting the separator 2 when it descends. and a crease cutter 7 that creates creases on the separator 2.
It is characterized by comprising: a crease cutter 7 for scoring the separator 2; and a holder 8 for the cutters 6 and 7 below the crease cutter 6 and the crease cutter 7. .

[0007]

[Function] Since the crease cutter 6 makes a crease at a predetermined position on the separator 2 in advance, the crease is reliably folded and there is no variation in the folding dimension.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained based on the drawings. 1 to 8 are side views of main parts sequentially showing the process of stacking electrode plates by the apparatus of the present invention. In the drawings, 1 is a folded plate that has a cavity inside and has a plurality of elongated holes communicating with the cavity bored in the contact surface with the separator, and a nozzle for vacuum piping is arranged in series with the cavity; A shaft 1a is provided on one side, and the separator 2 can be rotated around the shaft 1a, and the separator 2 can be folded in a zigzag motion in combination with a back and forth motion (left and right motion in the figure). Reference numeral 3 denotes an elevator, which descends so that the upper surface of the stacked electrode plate group 4 is at a constant height. Reference numeral 5 denotes a pusher, which holds the electrode plate 10 transferred onto the separator 2 so that it does not move when the bottom portion is wrapped around it. Reference numeral 6 denotes a folding cutter, which is used to preliminarily set folds on the folds of the separator 2 to make it easier to fold the separator 2 in a zigzag manner. Reference numeral 7 denotes a cutter which makes a cut in advance at the end of the separator 2 when the stacking of the electrode plates is completed, making it easier to push and cut the separator 2 with the pusher 5. Reference numeral 8 denotes a pedestal when the fold cutter 6 and cut cutter 7 make folds, and the separator 2 passes through the upper surface thereof. A pair of rollers 9 feed the separator 2 to the elevator 3 side.

Next, the method of the present invention will be explained using the apparatus of the present invention having the above configuration. In order to stack one more electrode plate 10 on the upper surface of the electrode plate group 4 in FIG. 1, one electrode plate 10 is placed on the upper surface of the separator of the electrode plate group 4 as shown in FIG. 3, lower the crease cutter 6 onto the upper surface of the holder 8 to form a crease at a predetermined position on the separator 2, and fix the separator 2 between the crease cutter 6 and the holder 8 so that it does not shift. Then, the folding plate 1 is moved back as shown in FIG. Then, as shown in FIG. 5, the folding plate 1 is rotated 90 degrees around the axis 1a, advanced toward the electrode plate group 4, and rotated 90 degrees again as shown in FIG. At the same time, while lowering the elevator 3 by the thickness of the electrode plate 10, the pusher 5 is lowered to come into contact with the upper surface of the electrode plate 10 and hold the electrode plate group 4. Next, fold plate 1 into 9 parts as shown in Figure 7.
After rotating 0 degrees, pusher 5 is raised as shown in FIG. After that, when folding plate 1 is rotated 90 degrees again, Figure 1
One electrode plate 10 is stacked on the electrode plate group 4. By repeating the above operations, a predetermined number of electrode plates and separators 2 are stacked to complete the electrode plate group.

[0010] After stacking the electrode plates, the separator 2
3, the fold cutter 7 is lowered at the same time as the fold cutter 6 in FIG. When the state is reached, the pusher 5 is lowered to push the cut portion completely. Moreover, only when the separator 2 starts folding and after cutting, the separator 2 is adsorbed onto the folding plate 1 so that the separator 2 can be moved onto the elevator 3.

[0011]

[Effects of the Invention] Since the present invention is constructed as described above, it produces the following effects. (1) The separator can be bent to a certain size, and a storage battery with excellent quality can be provided. (2) Even small electrode plates can be stacked without collapsing. (3) Since the separator is pushed through by the cutter and the pusher, there is no need to provide the cutter and its cradle above the electrode plate group.
