Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic electrode group stacking machine for storage batteries that stacks electrode plates and separators of storage batteries to form electrode groups.

The conventional method of stacking pole groups in storage batteries is to use a mechanism using a cam or crank to project the positive and negative plates onto a running chain and arrange them alternately. Generally, a separator is made to protrude above the positive and negative electrode plates, and at the end of the chain, the required number of positive and negative plates on which the separator is placed are stacked to form a pole group. .

However, with this method, it is difficult to hold the electrode plates on the chain and to position the separators during supply, making it impossible to stack them accurately, and therefore requiring a separate process to correct the stacked state of each plate.

Also, depending on the separator, it may be difficult to correct the position relative to the electrode plate. In such cases, sequence control is used to move many air cylinders and stack the negative electrode plate, separator, positive electrode plate, and separator in sequence at a fixed position. The method used is to lower the poles one by one and stack the required number of poles to form a pole group, which is then taken out.

However, this one-type air cylinder requires a large number of mechanisms for many movements such as ejecting the positive and negative electrode plates, connecting them to the stacking position, supplying the separator, and lowering the electrode group, and also However, it has the disadvantage that it is inferior to mechanical systems, and its mechanism is complicated, making maintenance difficult.

doctor The present invention will be explained below with reference to one embodiment thereof.

That is, FIG. 1 is a schematic front sectional view of one embodiment of the present invention, FIG. 2 is a schematic left sectional view of FIG. 1, and FIG. 3 is a schematic right sectional view of FIG. 1.

In the drawing, 1 is a bed, a lower frame 2 is attached on the bed 1, and a base 3 is placed on the lower frame 2. Further, an upper frame 4 is attached to the base 3, and a roof 5 is arranged on the upper frame 4. These bed 1, lower frame 2, base 3, upper frame 4, and roof 5 are made of steel plates and are integrated by welding.

A first camshaft 6 is attached to the lower frame 2, a second camshaft 7 is attached to the upper frame 4, and a lower rear shaft 8 and a lower front shaft 9 are attached to the lower frame 2. An upper rear shaft 10 and a lower front shaft 11 are attached to the frame 4.

Also, for every rotation of the first camshaft 6, the second camshaft rotates twice.
It is equipped with a power transmission mechanism consisting of a chain and sprockets that allow it to rotate, and these are driven by a motor with a continuously variable transmission.

Next, the stacking mechanism will be explained. That is, an elevator lowering lever 14 having a roller 13 that moves following an elevator lowering cam 12 attached to the first camshaft 6 is fitted to the lower front shaft 9. In the drawings, the shape of each cam is omitted. Further, an arm 15 is fitted to the lower front shaft 9, and the elevator lowering lever 14 and the arm 5 are connected to a one-way clutch mechanism that transmits the rotational motion of the elevator lowering lever 14 only in the direction in which the tip of the arm 15 descends. , arm 1
5 from the rotational movement of the elevator lowering lever 14. Further, the tip of the arm 15 is connected to a rod 18 of the elevator 17. Furthermore, arm 15
A force is applied by a spring in the direction that the tip of the elevator 17 rises, but this spring has relatively low tension, and therefore also has the function of buffering the force applied to the elevator 17. A positive electrode plate A, a negative electrode plate B, and a separator C are sequentially sent to the elevator 17.
At the same time, the elevator 17 descends and a desired pole group is formed.

After the desired pole group is formed, the electromagnetic clutch mechanism of the cam clutch 16 is disengaged, and the elevator 17 is lowered by operating the elevator raising actuator 19 connected in series with the rod 18. After that, the elevator 17 is lowered by a robot or the like. The group of poles is taken out and sent to the next process on a conveyor. Then, the elevator raising actuator 19 is operated so that the elevator 17 is raised, and the stacking of the next pole group is started.

Next, the separator supply mechanism will be explained.

A slide 20 that slides in the front-rear direction is arranged on the base 3, and the slide 20 has a separator supply lever 22 fitted on the rod 21 to the upper rear shaft 10.
The separator supply lever 22 is connected to the roller 23
The separator supply cam 24 is attached to the second camshaft 7 and moves in the same direction. Further, a guide 25 is provided at the front of the upper frame 4, and a cutter 26 is arranged so as to be guided by the guide 25. The cutter 26 also moves up and down in conjunction with the rotation of the second camshaft 70 by means of a cam, lever, etc. In other words, the rolled long separator E is moved to the slide 2 by a roller feeder or the like.
It is sent to the top surface composed of 0 vacuum type pads,
The separator E is adsorbed by the separator E and is pushed forward by a certain length, and then the cutter 26 descends to cut the separator E. Next, with the vacuum released, only the slide 20 moves back, and this is repeated one after another.
A separator C of a predetermined length is placed on the positive electrode plate A or the negative electrode plate B of the electrode group.

By the way, the electrode group usually has a structure in which a separator C is interposed between a positive electrode plate A and a negative electrode plate B, and negative electrode plates B are arranged at both ends of the separator C.

Therefore, in a device that repeatedly stacks negative electrode plate B, separator C1, positive electrode plate A, and separator C, after the stacking of the electrode groups is completed and before the stacking movement of the next electrode group, at least separator C1 positive electrode plate A1 The stacking movement of separators C would have to be omitted.

Here, in this device, this operation is performed by operating the separator supply lever disconnection actuator 27 consisting of an air cylinder attached to the roof 5 to the stow/bar 28 provided on the separator supply lever 22 at a time when the supply of the separator C is not necessary. This is accomplished by providing a bus mechanism that disconnects the separator supply lever 22 from contact with the separator supply cam 24 and stops the supply of the elongated separator E.

Next, the electrode plate supply mechanism will be explained. A plate 29 is also attached to the guide 25, and a pad 30 for adsorbing the positive electrode plate A and the negative electrode plate B is attached to the plate 29.
A holder 32 is attached for vertically guiding a shank 31 provided with a shank 31. The plate 29 is connected via the rod 33 to a plate supply lever 34 fitted on the upper front shaft 11, and the plate supply lever 34 is connected to a plate supply cam attached to the second camshaft 7. Follow and exercise. Further, the holder 32 is connected at its rod 35 to a plate suction lever 36 fitted to the upper front shaft 11, and the plate suction lever 36 is connected to a plate suction cam attached to the second cam shaft 7. exercise by following.

That is, the positive electrode plates A or the negative electrode plates B sent out to the front of the elevator 17 by these electrode plate supply mechanisms are picked up one by one, and then moved back to the elevator 17.
The stacking operation can be performed accurately on the pole group that has already been set up.

Further, the electrode plate supply mechanism is also provided with a bus mechanism similar to that provided in the separator supply mechanism. In other words, when the positive electrode plate A or the negative electrode plate B is not required to be supplied, the electrode plate suction lever disconnection actuator 37 consisting of an air cylinder attached to the roof 5 is moved to the electrode plate suction lever 3.
The stopper 38 of No. 6 is operated to separate the plate suction lever 36 from contact with the plate suction cam, thereby stopping the supply of the plate.

Next, the delivery mechanism will be explained. In other words, a plate sending cam is attached to the first camshaft 6, and the first plate sending lever that moves following the plate sending cam is perpendicular to the axial direction of the first plate sending lever. A second electrode plate delivery lever is provided, which is disposed so as to have an axial direction of , and which swings following the swinging of the first electrode plate delivery lever.

In front of the elevator 17, a holder a mechanism 39 is provided which is connected to the second plate delivery lever and runs left and right.

Regarding this holder mechanism 39, FIG. 4 shows an enlarged plan view thereof, FIG. 5 shows an enlarged side view, FIG. 6 shows an enlarged front sectional view, and FIG. 7 shows a sectional view taken along the line A-A of FIG. 6. This will be explained in detail with reference to FIG. 8, which shows a sectional view taken along the line B--B in FIG.

That is, the frame 40 of the holder mechanism 39 has a recess 41 that is wider than the width of the electrode plate and is substantially spaced apart from the protruding mechanism and the stacking mechanism.

A positive electrode plate A or a negative electrode plate B is projected into the recess 41 by a protrusion mechanism, and a sole 42 is arranged on the outer side of the recess 41 of the frame 40, and the sole 42 prevents the electrode plate from entering the recess 41. It has a sandwiched structure. Further, a spring 43 that applies a force to the sole 42 in the direction of clamping the electrode plate, and a bar 44 that moves the sole 42 in the opposite direction to the direction of clamping the plate are provided.
4 is a disk 46 rotatably attached to a shaft 45 disposed at the center of the frame 40.
The soles 42 are configured to move in opposite directions via the bins 47 provided at the soles 6, so that the respective soles 42 perform opening and closing movements at the same time. By the way, the end of the bar 44 protrudes from the frame 40, and this protrusion hits the bolt head that protrudes from the running surface of the holder mechanism 39 at the running end, and moves the sole 42 to make the recess 41 into the pole plate. On the other hand, it is in a free state. Further, since this releasing operation acts in a direction that repulses the spring 43, the holder mechanism 39 is decelerated near the running end, and stopping at an accurate position is ensured. In addition, the acceleration caused by the deceleration of the pin allows the electrode plate to maintain its accurate position even in the released state. As described above, by using the holder mechanism 39 of the present invention, it is possible to send accurately positioned positive electrode plate A and negative electrode plate B to the electrode plate supply mechanism.

Next, a protrusion mechanism for protruding the positive electrode plate A and the negative electrode plate B provided on the left and right sides of the stacking mechanism into the recess 41 provided in the frame 40 of the front holder mechanism 39 will be explained. That is, in the protrusion mechanism, 48 is a magazine in which the positive electrode plate A or the negative electrode plate B is stored, and the magazine 4
8 is provided with a gate 49 at the lower front thereof for feeding the electrode plates forward one by one. Further, the protruding mechanism is provided with a pusher 50 that protrudes the plate forward from the rear lower part of the magazine 48, and a plate protruding lever 51 that slides the pusher 50, and a plate protruding lever 51 that drives the plate protruding lever 51. A cam 52 is attached to the first camshaft 6.

Further, a lifter 53 is arranged from below the magazine 48 to lift up the positive electrode plate A or the negative electrode plate B. The lifter 53 is connected to a plate lifting lever 54, and the plate lifting lever 54 is connected to the first camshaft 6 at its roller 55.
It moves by following the electrode plate lifting cam attached to it. In other words, the lifter 53 operates to prevent the weight of the electrode plates stored in the magazine 48 from hindering the protrusion of the electrode plates that should be ejected. Coupled with the operation of the air cylinder that laterally supports the electrode plates stacked at a certain height, the air cylinder is first cut while lifting the electrode plates with the Rifuku 53, and after being lifted, the air cylinder is lifted up to a certain height. Hold the remaining electrode plates with an air cylinder, then lower the lifter 53 to lower only a few electrode plates, and after protruding the electrode plates with the pusher 50, lifter 53 again.
By repeatedly lifting the electrode plate, the electrode plate can be protruded smoothly.

The protrusion mechanism is also provided with a bus mechanism.

In other words, this plate delivery bus mechanism operates the lifter 53 to operate the plate lift actuator 56, which is an air cylinder attached to the bed 1, at a time when it is not necessary to supply the positive plate A or the negative plate B, to remove the plates in the magazine 48. The structure is such that it cannot be lifted and pushed out by the pusher 50.

In addition, in this embodiment, a plate protruding lever cutting female actuator 57 is used to separate the plate protruding lever 51 from the plate protruding cam 52 in order to improve the operation of the pusher 50.
A plate delivery bus mechanism is also provided.

The automatic stacking machine for storage battery electrode groups according to the present invention is constructed as described above, and a diagram of the movement of each component is shown in Table 1. In this diadarum, for the sake of simplicity, the electrode group consists of two positive electrode plates A and three negative electrode plates B.
In addition, a configuration is shown in which the first camshaft 6 is operated for one rotation in order to take out the pole group.

Although one embodiment of the present invention has been described above, various embodiments of the present invention can be considered without departing from the spirit thereof. For example, in the above embodiment, the movement of the elevator lowering lever 14 is performed by the elevator lowering cam 12, but this movement may be derived from another lever or the like. In addition, by lowering the shank 30 of the electrode plate supply mechanism to an appropriate position and stacking positive electrode plates A or negative electrode plates B so as to press the electrode group, the elevator can be operated appropriately using only the one-way clutch mechanism without using the elevator lowering lever 14. Although it is possible to lower the elevator, it is better to forcibly lower the elevator using the elevator lowering lever 14 or the like in order to perform the operation accurately. Furthermore, although the above embodiment uses a spring to apply upward force to the arm 15 in the stacking mechanism, this may be replaced by applying appropriate pressure to the elevator lift actuator 19.

Furthermore, in the above embodiment, the separator supply mechanism is of a type in which the elongated separator E is fed and cut. The present invention may be implemented in a type in which a separator is sent in a meandering manner, as shown in No.

Further, in the above embodiment, two types of plate delivery bus mechanisms are provided, but it is of course possible to use only one of them. In this case, it is preferable to use the plate lift actuator 56 because it is structurally simpler.

As described above, according to the present invention, since there is no need to stop the movement of the cam, the electrode plates can be stacked accurately at high speed, and the speed can be easily changed.

Also, since various bus gutter grooves are provided, it is easy to change the number of electrode plates.

Furthermore, the delivery mechanism is designed to open and close in conjunction with left and right running movements, and has a simple structure, and the holder mechanism uses a spring, making it possible to accurately position the electrode plate. can.

In addition, since the stacking mechanism uses an elevator lowering cam and an elevator lowering lever, this operation is faster than one that uses a motor pole screw, and more accurate than one that uses an air cylinder. It can be performed. Furthermore, since this mechanism uses springs, even if there are slight variations in the thickness of the electrode plates, the electrode group is always pressed by adjusting the lift of the elevator, so there is no need to worry about cargo collapsing.

As mentioned above, the present invention has extremely great industrial value.
