Description

  The present invention relates to an alignment device for an electrode plate group for a lead storage battery and an alignment method for the electrode plate group for a lead storage battery that align the electrode plate groups constituting the lead storage battery.

A lead storage battery is configured by housing a plate group in which a plurality of positive plates and a plurality of negative plates are stacked with a separator interposed therebetween, and injecting an electrolytic solution. The electrode plate groups of such storage batteries are aligned before being stored in the battery case. Conventionally, as a method of aligning the electrode plate groups, a method of aligning the electrodes by regulating the ears of the electrode plates has been used. However, since the ears of the electrode plate made of lead are soft and difficult to be formed into a certain shape, they may not be aligned only by regulating the ears.
For this reason, some proposals are made about alignment and conveyance of the electrode group for lead acid batteries. As one of the techniques, Patent Document 1 discloses a technique for correcting the stacked state of the electrode group during conveyance. In this technology, a positive electrode plate, a separator plate (separator), and a negative electrode plate are put into a storage box in a predetermined order, and vibration is applied to the storage box during transportation of the storage box, and the electrode group is aligned by the applied vibration. However, there is a disadvantage that the apparatus is complicated and the equipment cost increases.

Hereinafter, the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, an electrode plate 1 of a lead storage battery includes an electrode plate body 2 filled with a positive electrode active material or a negative electrode active material, an ear 3 formed near one end of the upper portion of the main body 2, and The pair of feet 4 is formed at the lower portion of the main body 2, and the pair of feet 4 includes a foot 5 provided near one end of the electrode plate main body 2, and a foot 6 formed at a predetermined distance from the foot 5. It consists of
In the electrode plate 1, the electrode plate body 2 applied with the positive electrode active material is the positive electrode plate, the electrode plate applied with the negative electrode active material is the negative electrode plate, and the positive electrode plate and the negative electrode plate have the same shape. The electrode plate group A (see FIG. 2) is configured by alternately stacking a plurality of positive electrode plates and negative electrode plates so as to be reversed and interposing a separator plate 10 between these positive and negative electrode plates.
In addition, when it is not necessary to distinguish the said positive electrode plate and a negative electrode plate, it is only called an electrode plate below.

2 and 3 show an alignment device B for aligning the electrode plate group A. FIG. 2 is an explanatory view showing a state in which the electrode plate group A is sandwiched between thickness-direction position restricting portions 20 described later. FIG. It is explanatory drawing which looked at the alignment apparatus B from the front, and has shown the state which incorporated the unaligned electrode group A which interposed the separator 10 between the positive / negative electrode plates 1 and 1 in this alignment apparatus B. FIG.
The aligning device B includes a thickness direction position restricting portion 20 (see FIG. 2) for restricting the position of the electrode plate group A in the thickness direction and an electrode plate group aligning portion C for aligning the electrode plate group A.

  As shown in FIG. 2, the thickness direction position restricting portion 20 includes a pair of thickness direction position restricting plates 21, 21. In this embodiment, the electrode plate group A is divided into the pair of thickness direction position restricting plates 21, 21. 21 and has a function of moving the electrode plate group A to the electrode plate group aligning portion C. In the present embodiment, the thickness direction position restricting unit 20 is used as a method of incorporating the electrode plate group A into the alignment part C. However, instead of the thickness direction position restricting unit 20, the electrode plate group A is separately conveyed. It is also possible to prepare a transport device that does not, and to incorporate the electrode plate group A into the alignment unit C with the transport device.

  The thickness direction position restricting plate 21 constituting the thickness direction position restricting portion 20 of the present embodiment has an open concave opening 22 on the upper side as shown in FIG. 3, and the electrode plate group A is aligned. After that, a gripping member for movement (not shown) is inserted into the concave opening 22 and the electrode plate group A is gripped by the gripping member so that the electrode plate group A is moved to the next process. Yes. In addition, the movement of the electrode plate group A to the next process can be transferred by sandwiching the electrode plate group A by the thickness direction position restricting unit 20. Further, when the distance between the electrode plate group aligning device B and the next process is large, the aligning device B can be moved.

  As shown in FIG. 3, the electrode plate grouping portion C includes an ear position restricting device 30 that restricts the position of the ear 3 of the electrode plate 1, a lower position restricting portion 40 that restricts the lower position of the electrode plate body 2, The foot position restricting portion 50 restricts the height of the legs 5 and 6 and the separator position restricting portion 60 restricts the position of the separator 10.

The ear position restricting device 30 includes a pair of ear position restricting plates 31 and 31 and a lowering assisting device 32 that pushes down the ear 3 of the electrode plate 1.
The foot position restricting portion 50 includes a pair of foot position restricting plates 51 and 51 and a vertical position restricting device 52.
The separator position restricting unit 60 includes a pair of separator side face restricting plates 61 and 61 that restrict the side face of the separator 10 and a separator upper restricting device 62 that restricts the upper part.

  The electrode plate group A is aligned by the electrode plate group aligning device B in the following steps. Note that the order of these steps is arbitrary.

As described above, the separator plate 10 is inserted and stacked between the positive electrode plate 1 and the negative electrode plate 1 to form the unaligned electrode plate group A.
At this time, the positive electrode plate 1 and the negative electrode plate 1 are arranged so that the positions of the respective ears 3 are divided into left and right. When arranged in this manner, the pair of legs 5 and 6 formed on the positive electrode plate 1 and the pair of legs 5 and 6 formed on the negative electrode plate 1 are stacked such that the respective legs are alternated (see FIG. 3).

Step of Setting to Alignment Device B As shown in FIG. 2, the stacked electrode plate group A is sandwiched between a pair of thickness direction position restricting plates 21, 21 of the thickness direction position restricting portion 20 and set to the alignment device B. .
Alternatively, the stacked electrode plate group A is held by a conveying gripping member (not shown), set on the alignment device B, the transfer device is removed, and the thickness direction of the electrode plate group A set on the alignment device B is increased. The thickness direction position restricting portion 20 is sandwiched between the thickness direction position restricting plates 21 and 21. The thickness (dimension in the thickness direction) of the electrode plate group A is measured by sandwiching the electrode plate group A between the control plates 21 and 21 of the thickness direction control unit 20.
If the electrode plate group A is set in the aligning device B, a predetermined width is widened between the regulating plates 21 and 21 of the thickness direction position regulating unit 20 with reference to the dimension in the thickness direction. That is, the tightening force of the restriction plates 21 and 21 of the thickness direction position restricting portion 20 is loosened as long as each electrode plate 1 is movable and does not tilt in the thickness direction. At this time, the position of the vertical position restricting device 52 of the foot position restricting unit 50 is flush with the lower position restricting unit 40, and the foot 4 of the electrode plate group A is placed on the vertical position restricting device 52. (See FIG. 4A).

Separating Plate Position Restricting Step When the electrode plate group A is set on the aligning device B and the tightening force of the restricting plates 21 and 21 is released, the position of the separating plate 10 is aligned as shown in FIG. The separators 10 are aligned by moving the pair of side surface restricting plates 61 and 61 of the separator position restricting unit 60 from the left and right sides, pushing the separator 10 from the side, and separating the separator 10 from above from the upper part of the separating plate upper restricting device 62. The separator 10 is pressed down at a predetermined position.

Ear Position Restriction Step As shown in FIG. 4 (b), a pair of ear position restriction plates 31, 31 of the ear position restriction device 30 that restricts the ear 3 of the positive electrode plate 1 is moved to make the ear 3 of the positive electrode plate 1 predetermined. Move to the position. Since the electrode plate group A is not tightened by the thickness direction position restricting portion 20, it can be easily moved (because the tightening is loosened), and the position of the ear 3 is aligned by this operation. Similarly, the pair of ear position restricting plates 31 and 31 of the ear position restricting device 30 is also moved with respect to the ear 3 of the negative electrode plate 1 to move and align the ear 3 of the negative electrode plate 1 to a predetermined position. It is preferable to align the ears 3 of the positive electrode plate 1 and the negative electrode plate 1 simultaneously.
In the embodiment, the pair of ear position restriction plates 31 and 31 are moved left and right to align the ears 3, but one ear position restriction plate 31 is fixed and the other ear position restriction plate 31 is one position restriction plate. The ears 3 may be aligned by moving so as to approach each other.

Foot Position Restricting Step As shown in FIG. 4C, when the ears 3 are aligned, the vertical position restricting device 52 that is flush with the lower position restricting portion 40 is lowered to support the foot 4. Remove. By removing the support of the foot 4, the electrode plate 1 is lowered by its own weight. At this time, it is preferable to assist the lowering of the electrode plate 1 by lowering the lowering assisting device 32. As a result, the lower end of the electrode plate body 2 and the separator plate 10 abuts on the lower position restricting portion 40 and does not descend further, and the foot 4 of the electrode plate 1 protrudes below the separator plate 10. . In this state, the foot 4 is sandwiched and aligned by the pair of foot position restricting plates 51 and 51 of the foot position restricting portion 50 from both sides. Then, the alignment of the ear 3 by the ear position restricting device 30 and the alignment of the foot 4 by the foot position restricting plates 51 and 51 are performed a plurality of times as necessary (each is performed by opening and closing each restricting plate a plurality of times).
In addition, although the alignment of the foot 4 by the foot position restricting plates 51 and 51 was performed by moving the restricting plates to the left and right, in addition, the foot 4 was pushed up from the bottom by the vertical position restricting device 52 several times. It is also effective to adjust the position.
In the embodiment, the pair of foot position restricting plates 51, 51 are moved to the left and right to align the foot 4. However, one foot position restricting plate 51 is fixed and the other foot position restricting plate 51 is moved to the other foot position restricting plate 51. The foot 4 may be aligned by moving closer to the foot position regulating plate 51.

Lower Position Control Step Next, as shown in FIG. 4D, the vertical position control device 52 of the foot position control unit 50 is raised to the height of the lower position control unit 40. By raising the vertical position restricting device 52 to the height of the lower position restricting portion 40, the electrode plate 1 is raised and disposed at a predetermined position, and the electrode plate group A is aligned.

Final Step If the electrode plate group A is aligned in a regular state, the electrode plate group A is moved by the pair of side surface restricting plates 61 and 61 and the separator upper restricting device 62, and again the pair of restricting plates 21 of the thickness direction position restricting unit 20; 21 is sandwiched and conveyed to the next process. Alternatively, the electrode plate group A aligned by a transport device (not shown) is transported to the next process.

  In addition, each process in the said description can also be replaced | exchanged suitably, can be suitably changed with the number of the electrode plates 1 which comprise the electrode group A, the magnitude | size of the electrode plate 1, etc., By changing It may be possible to perform the alignment work effectively.

  As described above, in the past, the ear plate 3 of the electrode plate 1 was regulated and the electrode plate group was aligned. However, the ear 3 was soft and was not formed in a certain shape, so it could not be aligned. By using the aligning device of the present invention, the ear 3 and the pair of legs 5 and 6 are aligned at three points.

It is a top view which shows the electrode of a lead storage battery. It is a side view which shows the state which clamped the electrode group in one Embodiment of this invention with the thickness direction position control part. It is a top view which shows the state which accommodated the electrode group in the alignment apparatus in one Embodiment of this invention. It is explanatory drawing which shows the alignment process of the electrode group in one Embodiment of this invention in process order.
