Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a storage battery electrode plate feeding device for feeding electrode plates to a subsequent process such as an assembly process.

In this application, the term "electrode plate" refers to an anode or a cathode monopolar plate, or an anode or a cathode formed symmetrically with two monopolar plates with their ears located on opposite sides of the center. Refers to the cathode joint plate.

[Prior Art] In recent years, hybrid lead-acid batteries having an anode plate using a cast lattice body and a cathode plate using an expanded lattice body have come into widespread use.
This hybrid lead-acid battery uses a single electrode plate as the cathode and a jointed electrode plate as the anode.
Therefore, conventionally, when manufacturing this hybrid type lead-acid battery, separate storage battery plate supply apparatuses for single electrode plates and for joint electrode plates are used to supply the respective electrode plates. That is, the storage battery electrode plate supply device for a jointed electrode plate suspends the jointed electrode plate from the ears at both ends of the jointed electrode plate on a stock conveyor, conveys it, and holds it by suction with a suction tool. It is designed to be supplied one by one to the assembly process. In addition, since the monopolar plate feeding device for storage batteries has only one ear and cannot be hung, the monopolar plate is picked up one by one from a stack of monopolar plates using a suction tool on a conveyor. It is designed to be supplied to the assembly process by being sucked and held and transported.

[Problems to be solved by the invention] However, as mentioned above, if the single electrode plate and the joint electrode plate are supplied to the assembly process using two types of supply devices, the equipment cost will increase and the operation time will be reduced. There were problems such as maintenance and inspection of the equipment becoming troublesome.

An object of the present invention is to provide a storage battery electrode plate supply device that can supply single electrode plates and joint electrode plates to an assembly process using a common device.

[Means for Solving the Problems] The present invention will be explained based on the embodiments shown in FIGS. A suction transfer conveyor 1, a main elevator 5 disposed below the suction transfer conveyor 1 on the front side in the transfer direction and supplying the electrode plate 3 to the suction tool 4, and a suction transfer conveyor 1 from the position where the main elevator 5 is arranged. A sub-elevator 6 which is arranged on the transfer side of the transfer conveyor 1 in the transfer direction and supplies the electrode plates 3 to the suction tool 4 after the supply of the electrode plates 3 from the main elevator 5 to the suction tool 4 is completed, and the main elevator 5
An endless stock conveyor 1 that supplies electrode plates 3 to
6, and an endless conveyor 21 disposed below the suction transfer conveyor 1 on the transfer side in the transfer direction to receive and convey the electrode plate 3 adsorbed by the suction tool 4. In the present invention, the electrode plate feeding device includes at least two rows of conveyor sections 2 arranged at mutual intervals such that the suction transfer conveyor 1 can cooperatively convey the same jointed electrode plate 3B;
It is composed of a suction tool 4 supported by each conveyor section 2 in a corresponding manner so that the same jointed electrode plates 3B can be sucked together, and the stock conveyor 16 and the conveyor 21 each have the same jointed electrode plates 3B. It is characterized in that it is constructed using at least two rows of conveyor sections 22 disposed at mutual intervals so that they can cooperate with each other to convey.

[Function] When the suction transfer conveyor 1 and the transfer conveyor 21 are configured in this way, the monopolar plate 3A can be transferred by using the conveyor parts 2 and 22 of the two rows of the conveyors 1 and 21 separately for each row. On the other hand, by using the two rows of conveyor sections 2 and 22 of the conveyors 1 and 21 together, the multipolar plate 3B can be conveyed.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

The storage battery electrode plate supply device in this embodiment includes an adsorption transfer conveyor 1. The suction transfer conveyor 1 includes two rows of conveyor sections 2, such as endless belts or chains, arranged at mutual intervals such that the same jointed pole plates 3B can be conveyed together, and each conveyor section 2 has the same jointed pole plates 3B. A large number of vacuum-type suction tools 4 are supported in correspondence with each other so as to be able to adsorb the objects. The conveyor section 2 is driven by a drive means such as a motor (not shown), so that each suction tool 4 is intermittently moved in the direction of the arrow shown in the drawing. Each suction tool 4 is a single electrode plate 3A of an anode or a cathode, or a joint electrode plate 3B of an anode or a cathode.
It is designed to absorb. Although not shown, the suction transfer conveyor 1 is designed to move up and down as a whole, and each suction tool 4 is reciprocated between a proper suction position and a retracted position. A main elevator 5 is disposed below the suction transfer conveyor 1 at the front side of the conveyor 1 in the transfer direction and at a position corresponding to the intermittent stop position of the suction tool 4, and on the transfer side from the main elevator 5. A sub-elevator 6 is disposed at a position corresponding to the other stop position of each suction tool 4. The main elevator 5 has a plurality of laminated plates 7
The electrode plate support 8 is provided with an electrode plate support 8 on which the electrode plate is placed, and the support 8 can be moved in the vertical direction by a driving means 9 such as a cylinder. Also, sub-elevator 6
Similarly to the main elevator 5, the plate support 10 is provided on which a stack 7 of a plurality of electrode plates 3 is placed.
0 can be moved up and down by a driving means 11 such as a cylinder. A first position detecting means 12 and a second position detecting means 13, such as a vertical limit switch, are arranged adjacent to the main elevator 5. Similar to the main elevator 5, a first position detection means 14 and a second position detection means 15, such as a limit switch, are arranged adjacent to the sub-elevator 6. The main elevator 5 and the sub-elevator 6 are arranged so that when the uppermost electrode plate 3 of the stacked body 7 placed thereon comes to the position where it is adsorbed by each suction device 4 of the corresponding suction transfer conveyor 1, the main elevator 5 and the sub-elevator 6 1 position detection means 12, 14
is activated, and the lifting operation of the electrode plate supports 8 and 10 is stopped. The main elevator 5 and the sub-elevator 6 each have a suction tool 4 to which the uppermost pole plate 3 of the stacked body 7 placed respectively corresponds.
When the top position of the stacked body 7 becomes lower by a predetermined distance due to adsorption to the second position detecting means 13,1
5, the electrode plate supports 8 and 10 start to move upward, and in the process of the upward movement, the uppermost electrode plate 3 of the stacked body 7 is sucked by each suction tool 4 of the corresponding suction transfer conveyor 1. When the electrode plate support 8,
10 is configured to stop the lifting motion. In this way, the sub-elevator 6 is the main elevator 5.
The operation is similar to that, but when the main elevator 5 is supplying the electrode plates 3 to each suction tool 4, the electrode plates 3 are already attracted to all the suction tools 4 passing above the sub-elevator 6. , each electrode plate 3 on the sub-elevator 6 is not suctioned, and after each electrode plate 3 on the main elevator 5 has completely supplied each suction tool 4, each electrode plate 3 on the sub-elevator 6 is attached to each suction tool 4. It is now being supplied to A stock conveyor 16 is arranged below the suction transfer conveyor 1 and on the front side in the transfer direction, and extends parallel to the transfer direction. The stock conveyor 16 has a conveyor section 17 consisting of two rows of endless chains, and these conveyor sections 17 are driven by a drive means 18. A stacked body 7 in which a plurality of electrode plates 3 are stacked is placed on each conveyor section 17 at intervals of the suction tools 4, and these stacked bodies 7 are appropriately conveyed to the plate support stand 8 of the main elevator 5. supply. The main elevator 5 and the sub-elevator 6 have detection means 19, 20 that operate based on changes in gravity.
is provided. These detection means 19, 20
is activated when each plate support stand 8, 10 becomes empty, lowers the plate support stand 8, 10, and places a plurality of electrode plates on top of the empty plate support stand 8, 10. When the third stacked body 7 is placed, the control is activated to raise the electrode plate supports 8 and 10. A laminate 7 in which a plurality of electrode plates 3 are stacked is placed on the plate support base 10 of the sub-elevator 6 by appropriate means. Below the suction transfer conveyor 1 and on the transfer side in the transfer direction, a conveyor 21 is arranged parallel to the suction transfer conveyor 1, and the electrode plate 3 supplied from the suction transfer conveyor 1 is transported by the conveyor 21, for example. It is designed to be supplied to the next process such as the assembly process.
The conveyor 21 is constructed by two rows of conveyor sections 22 disposed at intervals such that they can cooperate to convey the same jointed electrode plate 3B. Each conveyor section 22 consists of an endless chain, and a plurality of claws 23 for hooking the electrode plate 3 are provided at both ends of each conveyor section 22 in the width direction at predetermined intervals. A conveyor 21 to which the electrode plate 3 is supplied from the suction conveyor 1
A detection means 24 for detecting the presence or absence of the electrode plate 3 on the transport conveyor 21 is arranged at the supplied position, and the detection means 24 is activated when the electrode plate 3 is supplied and placed on the transport conveyor 21. I'm starting to do that. When the detection means 24 is activated, a drive means (not shown) is activated to drive the transport conveyor 21, and the electrode plate 3 is transported a predetermined distance. A receiving plate 25 on which the electrode plate 3 is placed is arranged near the position of the detection means 24 of each conveyor part 22 and slightly protrudes upward from the upper surface of each conveyor part 22.

Next, the operation of the above device when the electrode plate 3 is a monopolar plate 3A of an anode or a cathode will be explained with reference to FIG. First, a large number of monopolar plates 3 are placed on the plate supports 8 and 10 of the main elevator 5 and sub-elevator 6 in advance.
The laminated bodies 7 of A are positioned and placed in two rows. The suction transfer conveyor 1 includes each suction tool 4 of each conveyor section 2.
is intermittently fed, and when the conveyor 1 stops, suction tools 4 are located above the main elevator 5 and the sub-elevator 6, respectively. Adsorption transfer conveyor 1
The suction tools 4 are moved back and forth between the suction proper position and the retracted position for each monopolar plate 3A located at the top of each stacked body 7 on the electrode plate supports 8 and 10 of each elevator 5 and 6. Move straight up and down to operate. When the suction tools 4 approach the monopolar plates 3A placed on the main elevator 5, each monopolar plate 3A is vacuum-adsorbed by these suction devices 4. When this suction operation is completed, at the next timing, the suction transfer conveyor 1 rises to the retracted position of the suction tool 4 and retreats, and during that time, the next transfer operation of the suction transfer conveyor 1 is performed, so that each suction tool 4 The attracted monopolar plates 3A do not collide with the monopolar plates 3A on the sub-elevator 6. In addition, when each monopolar plate 3A, which is sucked by each suction tool 4, is stopped corresponding to the sub-elevator 6, each monopolar plate 3A on the sub-elevator 6 is sucked by each suction tool 4, and each monopolar plate The upper limit of the electrode plate support base 10 of the sub-elevator 6 is limited so that it does not come into contact with the electrode plate 3A. Each monopolar plate 3A is attached to the suction transfer conveyor 1 by each suction tool 4 of the suction transfer conveyor 1.
When the uppermost position of each stacked body 7 placed on the main elevator 5 is lowered and the second position detection means 13 is activated, the main elevator 5 is driven upward. When the main elevator 5 is raised and reaches a predetermined position in this way, the first position detection means 1
2 is activated, and the ascending operation of the main elevator 5 is stopped. After repeating these operations and supplying all the monopolar plates 3A placed on the main elevator 5 to each suction tool 4, each suction tool 4 supplies each monopolar plate 3A to each suction tool 4.
The monopolar plate 3A passes over the empty main elevator 5 without adsorbing any monopolar plates 3A, and starts adsorbing each monopolar plate 3A from the stacked body 7 of the sub-elevator 6. At this time, since the plate support 8 of the main elevator 5 is empty, the detection means 19 is activated and the plate support starts to descend, and when the plate support 8 reaches the lowest position. Its descent is stopped at . At this position, the stack 7 is supplied from the stock conveyor 16 onto the plate support 8. When the stack 7 is placed on the plate support 8, the detection means 19 is activated and the plate support 8 starts to rise. When the monopolar plate 3A comes to the position where it is sucked by the corresponding suction tool 4, the first position detection means 12 is activated and its upward movement is stopped. Thereafter, the supply of monopolar plates 3A from the main elevator 5 is resumed.
These operations are repeated to transfer each monopolar plate 3A. In this case, the main elevator 5 is located in front of the sub-elevator 6 in the transport direction of each monopolar plate 3A, so when the main elevator 5 rises, priority is given to supplying each monopolar plate 3A from the main elevator 5. It will be done. When each monopolar plate 3A is transferred to the transfer side of the suction transfer conveyor 1 and the suction transfer conveyor 1 is located at the proper suction position, the vacuum of each suction tool 4 is released and each monopolar plate 3A is transferred to the transfer side of the suction transfer conveyor 1. 21 and placed on each of the receiving plates 25. When each monopolar plate 3A is placed on each receiving plate 25,
The detection means 24 is activated, and the transport conveyor 21 is driven by a drive means (not shown) to supply each monopolar plate 3A to the next process, such as an assembly process. Incidentally, when the plate support stand 10 of the sub-elevator 6 becomes empty, the detection means 20 is activated in the same way as in the main elevator 5, and the plate support stand 10 is lowered and stopped at the lowest position. A stacked body 7 of monopolar plates 3A supplied by is placed on a plate support 10. At this time,
When the detection means 20 operates to raise the electrode plate support 10 to a position where the monopolar plate 3A is attracted, the first position detection means 14 operates and stops the raising operation.

Next, the electrode plate 3 is a jointed electrode plate 3B of an anode or a cathode.
To explain the operation of the above-mentioned device in the case of , as shown in FIG. 3B are sucked and held together and transferred, and in the conveyor 21, two rows of conveyor portions 22 that are driven synchronously convey the same jointed electrode plate 3B. Other operations are the same as in the case where the polar plate 3 is the monopolar plate 3A.

In addition, when the above-mentioned polar plate 3 is a monopolar plate 3A,
The conveyor sections 22 of the conveyor 21 do not necessarily need to be driven synchronously.

Furthermore, if each elevator 5, 6 is equipped with a sensor such as a gravity switch, it is possible to automatically detect when a plate is missing, and to automate the replenishment of plates.

[Effects of the invention] As described above, according to the invention, the suction transfer conveyor and the transfer conveyor are each configured with at least two rows of conveyor sections having mutual intervals that allow the same jointed electrode plate to be conveyed in cooperation with each other. Therefore, if each adjacent conveyor section of each conveyor is used for each row, a monopolar plate can be conveyed, and if each adjacent conveyor section of each conveyor is used together, a jointed electrode plate can be conveyed. Therefore, single electrode plates and joint electrode plates can be transported using a common device, which reduces equipment costs and also has the advantage of easier maintenance and inspection than when two devices are used. .
