JPS6028574B2 - Positioning device for continuously forming expanded grids - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positioning device for an expanded grid that is continuously formed, and is capable of continuously manufacturing electrode plates for lead-acid batteries using an expanded grid that is continuously formed in a strip shape. The purpose of this is to perform positional adjustment (centering) in the width direction of the expanded grating with high precision and at high speed in the process.

In the continuous manufacturing process of electrode plates for lead-acid batteries, the processes that mainly require positional adjustment in the width direction of the expanded grid are the process of adjusting the thickness of the expanded grid, the pressing process, and the unfinished process of expanding the expanded grid. There is a punching process for forming current collecting ears in the processed part, and a paste application process.

By the way, for the purpose of regulating the position of the expanded lattice,
If you use a gutter-shaped guide 7, which is generally used to regulate the position of a belt-shaped member and has regulating rising walls on both left and right sides, as shown in Fig. 3, it cannot be positioned reliably and has many drawbacks. .

Because the guide works by pressing down on the frame ribs 6 located at both ends of the expanded lattice 5, both ends of the mesh structure are easily deformed by the external force W, as shown in the enlarged view of FIG. Needless to say, this will lead to insufficient positional adjustment, and in addition to this, it is expected that both ends will also be damaged. The positioning device of the present invention completely overcomes these drawbacks and enables more accurate positioning of the expanded grating.

For this purpose, a freely rotatable roll structure having disk-shaped protrusions as shown in FIGS. 1A and 1B is desirable. Hereinafter, the apparatus shown in the example will be explained. At symmetrical positions on both left and right end surfaces near the outer periphery of a freely rotating roller 2 fixed to a shaft 1, disk-shaped protrusions 3 are fixedly arranged at regular intervals along the outer periphery. It is preferable that the arrangement interval (pitch) P is approximately equal to the pitch dimension in the longitudinal direction of the developed mesh portions in contact with the unprocessed portions of the expanded grating.
Further, as described above, the inner dimension B between the pair of disc-shaped protrusions 3 fixed at symmetrical positions on both end faces of the roller 2 is the inner dimension B of the unprocessed portion 4 of the expanded band lattice 5, as shown in FIG. By setting the width A to be 0.1 to 0.8 wider than the width dimension A, clearance is provided when the protrusion joins to the mesh development part. To explain the operating principle of the positioning device here, as shown in FIGS. 2, 4, and 5, the disc-shaped protrusion 3 is a triangular shape that is formed in contact with the unprocessed portion 4 of the extended band lattice 5. However, as the expanded lattice is conveyed and advances in the longitudinal direction, the roller 2 freely rotates while the protrusions are still interlocked, and the 1st part of the mesh
As the extended band lattice 5 progresses, the next protrusion 3 and the triangular mesh expansion part iron together, similar to the iron engagement between a chain and a sprocket. 3 and the triangular mesh development part continuously interlock with each other.

Therefore, the expanded lattice progresses with its displacement in the width direction regulated and the position of the processed portion, that is, the entire lattice, determined. In addition, the unprocessed portion 4 of the extended band lattice 5
As is well known, the width dimension A is cut by a cutting blade of an expanded band processing machine, and is accurate without variation, so the alignment of the protrusions 3 is also smooth and the position can be regulated reliably. In addition, since the triangular mesh developed portion is connected to the sturdy unprocessed portion 4, its mechanical strength is strong, and even if the triangular mesh is formed in a continuous formation, the lattice will not be damaged as would be the case with a follower. Here, to further explain a specific usage example of the positioning device of the present invention, the sixth
A long continuous extended band lattice 8 (same as 5 above) shown in FIGS. .

In the paste application process, it is necessary to accurately fill the paste-like active substance 9 into the grid portions with defined positions, so the paste application process is performed by correcting the positional deviation in the width direction of the expanded grid 5. I need to guide you to machine 10,
In addition, protective vapors 11 and 12 are pasted on both the upper and lower surfaces of the electrode plate.
In order to wrap the paste in a more reliable position, it is effective to provide the positioning device of the present invention in front of the paste applicator. In the above-mentioned example, the disk-shaped protrusion is fixed to the roller, but it is also possible to make it rotatable with respect to the roller.
