Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a centering device that moves a battery plate, particularly a storage battery plate, and adjusts the center position of the plate to a predetermined position.

Conventional structure and its problems Until now, when wrapping a storage battery electrode plate with a bag-shaped separator or a U-shaped separator, the center (center) position of the electrode plate had to be corrected in advance in order to position the electrode plate in the center of the separator. I was performing a so-called centering operation.

An example of this is explained with reference to FIG. 1. 1 is an electrode plate whose support is filled with a paste-like active material, 2 is a pair of left and right chain belts for conveying this electrode plate, and 3a and 3b are chain belts. These are position correction guides provided on the left and right sides of 2. The guide bodies 3a, 3b were fixed to suitable supports, and the plate entrance portion thereof was curved outward to facilitate introduction of the plate.

Centering of the electrode plate using the position correction guides 3a and 3b is carried out by moving the electrode plate 1 in the direction of the arrow by means of the conveyor chain belt 2, and moving the electrode plate to the guide members 3a and 3b whose mutual interval is gradually narrowed. This was done by guiding the side edges of the electrode plates, thereby correcting the position of the electrode plates in accordance with the spacing between the guide bodies 3a and 3b.

However, since the guides 3a and 3b were fixed independently of the conveyor chain belt 2, as the pole plate 1 moved, its tip corner 1a hit the guide 3a or 3b as shown by the broken line, and the corner There was a problem that the separator was damaged or centered in an inclined state, which adversely affected the subsequent separator packaging process. Note that FIG. 2 is a front view of the conventional centering device shown in FIG. 1, viewed from the front.

Purpose of the invention The present invention solves these conventional problems,
The object of the present invention is to provide a centering device that can perform accurate centering without damaging the electrode plate.

Structure of the Invention In order to achieve the above object, the centering device for battery electrode plates of the present invention includes an electrode plate, a conveyor belt for conveying the electrode plate, and a centering device provided on the left and right sides of the conveyor belt so as to sandwich the conveyor belt. The present invention is characterized in that the position correcting body is composed of a pair of eccentric rolls and a position correcting belt stretched between them and moving in the same direction at the same moving speed as the conveyor belt.

With this configuration, the transported electrode plate will not be damaged by hitting the position correction belt, and will be gradually moved from the left and right to the center by the position correction belt, and the position correction belt will smoothly separate from the electrode plate. Therefore, centering, which is the positioning of the center (central) part of the electrode plate, can be performed accurately, and the packaging process using separators can be performed satisfactorily.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 3 to 5.

In the drawings, reference numeral 1 indicates an electrode plate, and reference numeral 2 indicates a chain belt, which is a conveyor belt, and these are similar to the conventional belt shown in FIG. Reference numerals 4a and 4b are position correcting bodies that are a feature of the present invention, and these are arranged so as to sandwich the chain belt 2 from the left and right sides.

The position correcting bodies 4a, 4b include a pair of eccentric rolls 5a, 5b, 5c, and 5d, and position correcting belts 6a, 6b made of, for example, rubber and stretched between them.
Consisting of Of the eccentric rolls 5a and 5c, as is clear from FIG.
By engaging the eccentric shafts 11a and 11c,
The eccentric shafts 11b and 11d that form a pair with the sprockets 12a and 12 rotate synchronously in opposite directions.
b, 12c, and 12d are linked by a chain (not shown) so that they are interlocked.

Furthermore, as is clear from FIG. 5, the left and right position correctors 4a and 4b have pairs of eccentric rolls 5a and 5b and 5c and 5d whose eccentric states are in the same phase, so that they do not rotate in the same manner as described above. Together, as shown by arrow A, the distance between the chain belts 2 is narrowed from the position of the broken line to the position of the solid line, so as to sandwich the chain belt 2.
The position correction belts 6a, 6b move in the direction of arrow B at the same speed as the chain belt 2 in the same direction.

Therefore, as the electrode plate on the chain belt 2 moves, it is sandwiched between the correction belts 6a and 6b from the left and right, and its position is corrected and centered to a predetermined center position. In addition, the correction belts 6a, 6b
After coming into contact with the electrode plate 1 and completing its centering, the electrode moves away from the electrode plate 1 without any force due to the eccentric rotation of the eccentric roll, and reaches a waiting state for centering the next electrode plate.

Effects of the Invention As described above, according to the present invention, it is possible to accurately center the electrode plate without damaging it, and in the subsequent packaging process of the electrode plate with the separator, the electrode plate can be placed in the center position of the separator. The packaging process of the separator can be carried out well. Furthermore, if it is provided before the step of aligning the electrode plates, the phase plates can be stacked together efficiently and accurately.
