Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated apparatus for forming an electrode plate such as a primary battery, a secondary battery, and a fuel cell, an unformed electrode plate, and a substrate.

2. Description of the Related Art Generally, an electrode plate for a battery is often produced by filling a porous material such as a lattice or lath plate with a paste-like or slurry-like active material or a substrate material, and further performing a chemical charging treatment or sintering. Here, all the electrodes including the unfinished electrode plate and the completed electrode plate in the manufacturing process are collectively referred to as an electrode plate. In these processes, the electrode plates are often handled in an integrated manner because of space efficiency, control of conditions, and the like. However, in recent years, there has been a remarkable progress in high-speed production technology for the basic part of electrode plate production in which paste is filled and processed into an electrode plate shape, but on the other hand, the subsequent electrode plate handling technology lacks appropriateness. Therefore, even if it is made at a high speed, there is an imbalance in the production response capability, such as collecting the plates that are transported flatly arranged on the belt conveyor and arranging them at a predetermined location in an integrated state. This delay seems to be due to the difficulty of mechanical handling such as the fact that the electrode plate is relatively soft or brittle. From this point of view, recently, without picking up or lifting the pole plate carried by the belt conveyor at high speed, the inertia of the conveyor conveyance is used to some extent, and the discharge from the end of the conveyor to the air is used to help other power. A method has been developed in which the air is discharged into the air, dropped to a substantially fixed place, and the collected air is collected and accumulated on the accumulator while the appropriate accumulator is sequentially lowered.

The problem to be solved by the invention is that even when the method is conveyed at a high speed, the single function has the ability to accumulate and is extremely convenient for handling the electrode plate. The problem remains in the work of replacing with a newly prepared stacking machine after the stacking of the stacking is completed. In other words, the production speed of the electrode plates in recent years depends on the contents of the electrode plates, but in the case of the most advanced expansion method of lead-acid batteries, the capacity is more than 200 sheets / minute in a single row. Is on the order of 1/100 second.

How to steadily switch the integrator from the preparation stage to the capture stage during this short time can be said to be the key to the success of this high-speed integration. From this point of view, the stacking platform, which stands in the horizontal direction of the electrode plate falling from the air at a position close to the conventional capturing system, can be ejected from the stacking machine, or the stacking platform can be moved together with the stacking plate to move A method of plugging in below was attempted.
However, it will be moved a distance close to the width and length of the electrode plate, and there is a limit to the time of insertion, so that the falling electrode plate is thrown away or the electrode plate is distorted,
It was to build a pile of defective products immediately.

Means for Solving the Problems Accordingly, the present invention as a specific means, a conveyor for continuously transporting a plurality of electrode plates, a mechanism for discharging the electrode plates almost in an extended line of the conveyor, and capturing the released electrode plates. An accumulator that descends and accumulates in accordance with the amount of accumulation while accumulating, wherein the accumulator of the accumulator waits on an upper extension of the integrated electrode group higher than the flight line of the electrode, and a discharge interval of the electrode. The present invention is to provide an electrode stacking device characterized by comprising a mechanism for descending substantially vertically below the flight line of the electrode plate in time and starting accumulation.

Operation Since the present invention has the above-described configuration, the stacking surface is placed in the trapping system by lowering the stacking surface in a substantially vertical direction by only the thickness of one electrode plate and the thickness of the stacking table. In other words, if it is applied to a 2 mm thick electrode plate with a length or width of about 100 mm and the thickness of the stacking table is a 3 mm fork, the moving distance of the stacking table required for switching is theoretically the conventional of
It is 5/100, and it cannot be overstated that its ability to respond to high-speed switching is greatly improved. Moreover, since the preparation can be carried out with the capturing and collecting system, the certainty of the switching is so large as to be incomparable with the conventional method of moving the surface while making the system.

EXAMPLES Hereinafter, the features and effects of the configuration of the present invention will be described with reference to examples.

FIG. 1 shows an embodiment of the configuration of the present invention. Here, 1 is a belt conveyor for transporting the electrode plate 2 at high speed, 3 is an angle adjusting device for adjusting the direction in which the electrode plate protrudes in any direction, and 4 is an accumulating device. Basically, it is necessary to prepare a plurality of accumulating devices in order to continuously perform the collecting and collecting operations of the electrode plates. Reference numeral 5 denotes an integrated electrode group, and reference numeral 6 denotes an emitted and flying electrode plate. The mechanism for transferring the integrated electrode group to another site is combined as needed. Here, when switching the stacking machine during the continuation of stacking, first, the stacking device 4 is provided with the stacking platform 7 on the upper extension (A) of the stacking plate group 5 above the flight line of the electrode plate discharged from the stacking platform. Wait. Next, when a predetermined amount of accumulation of the preceding accumulation machine is completed, at least the accumulation platform is lowered substantially vertically to the lower flight line (B) to set the acquisition system. For this switching, the entire stacking machine may be lowered, but a method of fixing the main body of the stacking machine and lowering only the stacking table is also possible. The conventional method in which the stacking machine stands by next and the stacking table pops out to the position where the capture starts, and the compatibility with the present invention are 40 plates / min. Comparing the number of troubles called "choco stop" as the operation loss when connecting and accumulating in the transfer device, the present invention is improved to about 0 to 5 times compared to 20 to 30 times in the conventional example. Was.

Effect of the Invention As described above, the present invention is suitable for high-speed electrode plate integration and has an effect of measuring the operation stability. It can be achieved, and its industrial value is extremely large.
