Abstract

PURPOSE:To obtain a storage battery plate having uniform filling density on its both sides and good quality by installing a pressure sensor in the lower part of pasting belt and setting a pressure control roller in a paste hopper, then operating them coupled with each other. CONSTITUTION:When a grid G passes under a hopper 7, it is filled with paste P with pasting rollers 3 and 3'. A pressure sensor 10 is connected to the lower part of a pasting belt 6 through a contact device 11. When the filling pressure of the paste P to the grid G is low, the pressure sensor 10 increases the rotating speed of pressure control rollers 4 and 4' within a paste hopper 1. The flow of the paste P which is moved by pasting rollers 3 and 3' is interrupted and the filling pressure is increased to the specified pressure. Therefore, the grid G is filled with paste uniformly and densely.

Description

[Detailed description of the invention] The present invention relates to a belt type automatic plate line coating apparatus.

Conventionally, two pasting rollers with V-shaped grooves on the surface are installed inside the pasting hopper, and a grid body conveyed by a pasting belt passes directly below the pasting hopper. At this time, the paste attached to the pasting roller and rotating is filled into the lattice body, and the excess paste is removed using a spray scraper to form the electrode plate.

At this time, the rotating amount and speed of the paste by the pasting roller changes due to the mutual effect of the creeping length of the paste roller in contact with the paste and the centrifugal force, but compared to the conventional pasting roller. In this method, it is not possible to increase the pressure with which the paste is filled into the lattice body, and the lattice body cannot be uniformly filled, and in some cases, there are some areas where the paste is not filled.

In particular, the above problem is closely related to paste density, and as the amount of water in the paste or the content of addition 1j increases, the paste state becomes more fluid.Therefore, in conventional pasting methods, the filling density of the paste is The problem was that it could not be improved.

Therefore, in the present invention, a pressure sensor is installed below the pasting belt, and the pressure adjustment roller in the pasting hopper, which can adjust the paste filling lateral pressure based on the sensor signal, is driven. The aim is to significantly improve the

That is, a pressure sensor is installed on the lower surface of the pasting belt to measure the pressure of filling the paste into the grid, and a roller is installed in the pasting hopper so that the pressure of filling the paste into the grid can be adjusted by the sensor. By this, the paste filling pressure into the grid body can be adjusted arbitrarily, and even depending on the type of paste, the paste can be filled into the grid body with sufficient filling pressure, ensuring uniform and stable quality.
It is possible to obtain an electrode plate of ~.

An embodiment of the present invention will be described below.

1 is a pasting hopper, 2 is a stirring arm for paste P, 3.3' is a L7'c pasting roller with a 7-shaped groove on its surface, 4.4' is a pressure adjustment roller, and 5 is the surplus in the paste. Soufraper, 6 is lattice body G
a pasting belt that conveys the lattice body and serves as an electrode plate; 7 is a dowel that covers the part of the lattice body G that does not need to be filled with paste; 8 is a small roll for feeding the lattice body G into the pasting hopper IK;
9 is a pasting roller 3.3'tl [l gear;
10 is a pressure sensor 12 provided below the pasting belt 6 and having a contactor 11 that is in constant contact with the belt 6;
is the gear of the pressure adjustment roller.

The lattice body G conveyed by the pasting belt 6 is reliably fed into the pasting hopper 1 by the small roll 8, and is passed directly under the rotating flow of paste P by the pasting roller 3.3'. pass. The stirring arm 2 acts on the pasting roller 3.3' so that the base) P is sufficiently distributed. The pad 7 covers the portions that do not require paste filling, and only the portions of the grid G that require pasting are exposed to the pasting roller 3.3'.

While the grid G thus fed is passing under the hopper 7, it is filled with υ base) P by the pasting roller 3.3'. At this time, when the filling pressure of the paste P into the grid body G is low, the pressure sensor 10 which is in contact with the contactor 11 below the pasting belt 6 detects the pressure adjustment roller 4 in the pasting hopper 1. The rotating speed of the pasting roller 3.4' is controlled quickly, and the flow of the paste P being rotated by the pasting roller 3.3' is blocked.
The filling pressure is increased to a predetermined pressure by the paste flowing one after another, and the grid body G is uniformly filled with high density.

Therefore, according to the present invention, even if the state of the paste changes, the paste can be filled with a predetermined filling pressure, and
Control of the filling machine can be greatly simplified and labor can be saved.

Same, Haste stirring arm, pasting roller 3.3
' and the small roll 8 are driven by the coating machine main body via a gear 9 and the like.

As described above, the present invention improves the pasting pressure by installing a pressure sensor below the pasting belt and interlocking the pressure adjusting roller in the pasting hopper, so that the filling density can be adjusted from front to back. It is believed that it is possible to provide storage battery plates of uniform and high quality, and its industrial value is enormous.
