Abstract

PURPOSE:To automatically fabricate a group of electrode plates at high productivity by arranging succesive separators zigzag by means of oscillation of the upper side of each separator in the horizontal direction, while alternately stacking negative and positive electrode plates together. CONSTITUTION:A traverser 1 is moved leftward and a negative electrode plate 5 located on a lifter 4 is held by the clamp 6 of the traverser 1 and then the traverser 1 is moved rightward and separators 3 are then expanded on a dummy plate 8 and the plate 5 is put on the separators 3. Similarly, the separators 3 arranged zigzag and a positive electrode plate 11 are stacked on an electrode plate during the rightward movement of the traverser 1 and by repetition of the above process the separators 3 are arranged zigzag and the electrode plates 5, 11 are stacked together to form a group of electrode plates and then the separators 3 are cut by a cutter 14 and in this way a group of electrode palates for a storage battery are automatically fabricated at high productivity.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method and apparatus for alternately stacking storage battery plates with separators interposed therebetween.

Prior art and its problems Conventionally, for example, Japanese Patent Application Laid-open No. 123665/1983
"Folds are formed at regular intervals on a continuous flexible separator so that the directions of the folds alternate, and anode plates and cathode plates are alternately inserted between the separators to match the folds. method” is disclosed. In this assembly method, while supplying a folded separator into a jig, the worker alternately picks up the positive and negative electrode plates stacked on the left and right sides of the jig, It was inserted according to the folding tendency of the separator. For this reason, the number of electrode plates that one worker can produce is limited, and
When the electrode plate becomes large, it becomes impossible to hold the electrode plate with one hand, which causes a problem that production efficiency further decreases.

Purpose of the Invention The present invention has been made in view of the above problems, and includes:
The purpose is to provide a method and apparatus for automatically manufacturing electrode plate groups with excellent productivity.

DESCRIPTION OF THE INVENTION The present invention is a method of manufacturing an electrode plate group for a storage battery and an apparatus therefor as described in the claims.

Example An embodiment of the present invention will be described based on the drawings.

1 and 2 are explanatory diagrams for manufacturing an electrode plate group using the apparatus of the present invention, in which 1 is a traverser, 2 is a guide roller that supplies a separator 3 below the traverser 1, and 4
is a lifter that lifts up the negative electrode plate 5, 6 is a clamp that grips the negative electrode plate 5, 7 is a pusher that pushes the negative electrode plate 5 downward, 8 is a dummy plate for separating the electrode plate groups, and 9 is a place on which the electrode plate groups are placed. 10 is a lifter for lifting the positive electrode plate 11; 12 is a clamp for gripping the positive electrode plate 11;
13 is a pusher for pushing the positive electrode plate 11 downward, 14 is a cutter for cutting the separator 3, and 15 is a side wall of the hole through which the pole group elevator 9 moves up and down.

In FIG. 1, the traverser 1 moves to the left (in the direction of the arrow) to pick up the negative electrode plate 5 placed on the lid 4. When the traverser 1 comes to this position, the lifter 4 pushes up the negative electrode plate 5 to the position of the clamp 6, and then
, and grip the negative electrode plate 5. At this time, the dummy plate 8 moves forward above the pole group elevator 9, and the lower end of the separator 3 is held between the dummy plate 8 and the pole group elevator 9.

Next, the traverser 1 moves to the right side, and when it comes to the position shown in FIG. When the negative electrode plate 5 is dropped, the separator 3 is pulled downward by the weight of the negative electrode plate 5, and the negative electrode plate 5 is placed on the dummy plate 8 via the separator 3.

Then, the pusher 7 pushes the negative electrode plate 5 downward, and the separator 3 comes into close contact with the dummy plate 8 and the negative electrode plate 5.

During this operation, the positive electrode plate 11 transported onto the lifter 10
is held with the clamp 12.

When the above operation is completed, the traverser 1 moves to the position shown in FIG. 1, the separator 3 is stretched diagonally from the lower right to the upper left, and the negative electrode plate 5 is gripped with the clamp 6 in the same manner as above. At the same time, the clamp 12 is opened, the positive electrode plate 11 is stacked on the negative electrode plate 5 via the separator 3, and the pusher 13 is pressed down.

When one negative electrode plate 5 and one positive electrode plate 11 are stacked in this way, the separator 3 is cut with the cutter 14, the dummy plate 8 is pulled out to the right, and the electrode group elevator 9 is undersewn in small increments. , stack the electrode plates up to a predetermined number. After stacking the electrode plates, the dummy plate 8 is moved forward again onto the electrode plate group, and while holding the separator 3 between the dummy plate 8 and the electrode plate group, the negative electrode plate 5 and the positive electrode plate are placed on the dummy plate 8 again. 1
1 and cut the separator 3 with a cutter 14 provided on the wall 15 located at the tip of the dummy plate 8.
One cycle of stacking the electrode plate group is completed.

Effects of the Invention As described above, according to the method of the present invention, it is possible to automate the manufacturing method of electrode plate groups for storage batteries using meander-folded separators, which was conventionally carried out manually. , production efficiency can be greatly improved.
