Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for changing the attitude of a rod member during the supply process thereof, for example, changing the supply attitude of a rod member suitable for supplying a carbon rod in a manufacturing process of a cylindrical manganese battery. Related to the device.

[0002]

[Related Background Art] In addition to increasing the capacity and improving the safety of this type of manganese battery, in recent years, among manganese batteries, the demand for alkaline manganese batteries has been increasing, and the production rate has been improving. It is strongly desired. In order to increase the production rate of a manganese battery, a carbon rod as a current collector must be supplied at high speed and stably. Here, the carbon rod is generally discharged from the hopper using its own weight, and in order to increase the supply speed of the carbon rod and facilitate the assembly of the carbon rod, after the carbon rod is discharged from the hopper, It is necessary to change the supply attitude of the carbon rod. That is, since the carbon rod is discharged from the hopper in a horizontal position, it is necessary to change the position of the carbon rod from the lying position to the standing position in the subsequent supply process.

Conventionally, dial rows or twist chutes have been employed to change the attitude of the carbon rod described above. The row of dials is rotatable vertically below the outlet of the hopper and is arranged vertically, and has a disk-shaped take-out dial having grooves formed at regular intervals on its outer peripheral surface, and is rotatable in the vicinity of the take-out dial. And a supply dial in the form of a disk having a similar groove on the outer peripheral surface thereof, and rotatably disposed between the take-out dial and the supply dial. A relay dial having a truncated conical shape having an outer peripheral surface that is in contact with the relay dial, and a groove is formed on the outer peripheral surface of the relay dial at the same interval as the take-out and supply dial.

When each of the above-mentioned dials is rotated in the predetermined direction at the same peripheral speed, the carbon rods in the hopper are received one by one into the groove of the take-out drum from the discharge port thereof and directed toward the relay dial. Supplied. After this,
The carbon rod on the take-out drum is received in the groove of the relay dial when its groove matches the groove of the relay dial,
It is supplied to the supply dial with the rotation. And, similarly, the carbon rod on the relay dial is also received in the groove of the supply dial when its groove matches the groove of the supply dial. The carbon drum discharged from the hopper is transferred from the take-out dial to the supply dial via the relay dial, thereby being changed from the lying position on the take-out dial to the standing position on the supply dial.
Needless to say, a guide cowl for preventing the carbon rod from dropping is provided outside each dial.

On the other hand, the torsion chute consists of a cylindrical pipe connected to the end of a horizontal supply path of the carbon rod. The cylindrical pipe has an upstream open end at the inlet of the carbon rod and a downstream open end at the open end. Defined as an outlet. A pair of spiral grooves are formed on the inner surface of the cylindrical tube from the inlet to the outlet, and these spiral grooves are horizontally separated at the inlet of the cylindrical tube. Vertically separated.

According to the above-mentioned torsion chute, when a carbon rod supplied in a press-and-press manner sequentially on the supply path in a recumbent position reaches the inlet of the cylindrical tube, the carbon rod is inserted into the corresponding spiral groove at both ends. In the fitted state, it is pushed into the cylindrical tube. Thereafter, the carbon rod moves toward the discharge port in the cylindrical pipe while both ends thereof are guided in the spiral groove, and in this moving process, the posture of the carbon rod is gradually changed, and Is discharged from the outlet of the cylindrical tube in a standing posture. Therefore, even in the case of a torsion chute, during the supply process of the carbon rod, the supply posture can be changed from the lying posture to the standing posture.

[0007]

In the case of the above-mentioned dial row, in order to stably deliver and receive the carbon rod between the adjacent dials, the grooves between the adjacent dials must be accurately positioned at a predetermined rotation angle position. The rotational phase of each dial must be positioned to match. However, the positioning of such a dial is very difficult, and its adjustment requires a great deal of labor and time.

In addition, since the carbon rod is brittle, the carbon rod is liable to crack when transferring between the dials, and it is difficult to stably secure a continuous supply of the carbon rod. On the other hand, in the case of a torsion chute, since the inner carbon rod is moved in a press-and-press manner while both ends thereof are guided by the spiral groove, not only is the posture easily unstable but also an excessive force is applied. In addition, the carbon rod is easily cracked. Such a crack in the carbon rod causes the carbon rod to become jammed or jammed in the twisting chute, but since the inside of the twisting chute cannot be seen from the outside, it takes a lot of time to remove the jamming and jamming. It takes time and it is not possible to secure a stable supply of continuous carbon rods.

Further, if the crack of the carbon rod is of the order of a crack, the carbon rod is discharged as it is from the twisting chute, and the crack cannot be detected. Further, since the carbon rod is very hard, the spiral groove of the twisting chute is significantly worn, and there is a problem in durability of the twisting chute. SUMMARY OF THE INVENTION The present invention has been made based on the above-described circumstances, and an object of the present invention is to provide a supply posture of a rod member that can stably secure continuous supply without damaging the rod member with a simple configuration. A change device is provided.

[0010]

The above object is achieved by a rod attitude changing device according to the present invention. The feeding angle changing device according to the first aspect of the present invention replaces the dial row and the twisting chute described above. Thus, a pair of endless belts that can run in synchronization with each other are used, and a sandwiching transfer passage for the rod member is secured between these endless belts. More specifically, the pair of endless belts are wound around the first and second pulleys, respectively.
The pulley and the second pulley have a first surface and a second
It is rotatably arranged in the plane, and thereby defines an inlet and an outlet of the sandwiching transfer passage between the first pulley and the second pulley.

According to the supply attitude changing device of the first aspect, the rod member guided to the introduction port between the first pulleys is sandwiched by a pair of endless belts, and is held by the endless belts while traveling. The inside of the transfer passage is supplied toward the discharge port between the second pulleys. In this supply process, the posture of the rod member is gradually changed according to the twist of the pair of endless belts.

According to a second aspect of the present invention, there is provided a supply attitude changing device including a travel guide inside each endless belt, and the endless belts extend along the nipping and transporting path to guide the traveling of the corresponding endless belt. I do. The traveling guide keeps the width of the holding transfer passage constant and stably holds the rod member between the pair of endless belts at a certain holding pressure.

According to a third aspect of the present invention, the pair of endless belts are timing belts, and the endless belts run synchronously with each other without slippage between the endless belts and the rod member.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, there is shown a part of a facility for manufacturing a cylindrical manganese battery, that is, an apparatus for supplying a carbon rod (rod member) C used for manufacturing a cylindrical manganese battery. . This supply device includes a hopper 2, in which a large number of carbon rods C are stacked and stored. The hopper 2 has a hopper outlet 4 at its lower end.
And a feed roller 6 below the hopper 2.
Are rotatably arranged. The outer peripheral surface of the feed roller 4 is lined with rubber.

A rod take-out passage 8 extends downward from the hopper outlet 4. The lower end of the rod take-out passage 8 is curved, and the lower end is opened horizontally on the outer peripheral surface of the feed roller 6. ing. The carbon rods C in the hopper 2 are taken out one by one into the rod taking-out passage 8 through the hopper outlet 4 by their own weight. The extracted carbon rod C descends in the rod extraction passage 8 and is continuously supplied to the outer peripheral surface of the feed roller 6 from the lower end opening. The rod take-out passage 8 can be constituted by a pair of guide plates 10 facing each other at an interval corresponding to the diameter of the carbon rod C.

From the feed roller 6, a carbon rod C
Supply path (not shown) extends horizontally, and the end of the supply path is connected to the dial 12. The dial 12 is horizontally and rotatably disposed, and a plurality of grooves 14 are formed at equal intervals on the outer peripheral surface thereof.
The end portion of the supply path of the carbon rod C described above is constituted by a supply posture changing device described later. The supply posture change device introduces the carbon rod C continuously supplied with the rotation of the feed roller 6. Received by mouth,
In the supply process, as shown in FIG. 1, the posture is changed from the reclining posture to the standing posture, and the posture is guided to the discharge port. Arrow A in FIG.
Shows the flow of the carbon rod C from the rod take-out passage 8 to the dial 12, and the twist of the arrow A represents the change in the attitude of the carbon rod C described above.

The carbon rod C that has reached the outlet of the supply attitude changing device is received in one groove 14 of the dial 12. Thereafter, the carbon rod C transferred along with the rotation of the dial 12 maintains its standing posture (see arrow B) at a predetermined rotation angle position of the dial 12 while maintaining a main supply line (see FIG. No). A guide cowl (not shown) is arranged outside the dial 12 from the outlet to the main supply line, and the guide cowl prevents the carbon rod C from dropping out of the groove 14. .

Referring to FIG. 2, the supply attitude changing device is specifically shown. The supply attitude changing device includes a pair of driven pulleys (first pulleys) 16 and power pulleys 18.
(A second pulley), and the driven pulley 16 and the power pulley 18 are toothed pulleys, and are disposed on the upstream side and the downstream side, respectively, when viewed in the supply direction of the carbon rod C. The pair of driven pulleys 16 have the same vertical surface 2
At a predetermined interval within 0, above and below the supply path,
The above-described inlet is defined between the driven pulleys 16. Each driven pulley 16 has a horizontally extending pulley shaft 22.
The ends of these pulley shafts 22 are rotatably supported by a frame (not shown). In FIG. 1, only the upper driven pulley 16 is shown.

On the other hand, the pair of power pulleys 18 are separated in the same horizontal plane 24 to the left and right of the supply path with the same interval as that between the driven pulleys 16, and the discharge port described above is defined between these power pulleys 18. Have been. Therefore, the arrangement surface of the pair of driven pulleys 16 and the pair of power pulleys 18, that is, the vertical plane 20 and the horizontal plane 24 are in a state orthogonal to each other. A timing belt (endless belt) 26 is wound around each driven pulley 16 and the corresponding power pulley 18, and the timing belt 26 has an arrangement surface of the driven pulley 16 and the power pulley 18 described above. Since they are orthogonal to each other, they are twisted by 90 °. Accordingly, the nipping transfer passage defined between the pair of timing belts 26 is also twisted by 90 °. Here, the passage width of the sandwiching transfer passage is set slightly smaller than the diameter of the carbon rod C.

The driven pulley 16 and the power pulley 18
Has disk-shaped guides on both sides thereof. These guides prevent the timing belt 26 from shifting in the axial direction of the pulley, but its outer diameter is smaller than the outer diameter of the portion of the timing belt 26 curved by the pulley. Further, a plate-like traveling guide 28 is arranged in each timing belt 26. Each traveling guide 2
8 is the timing belt 2 on the side that defines the nipping transfer passage.
No. 6 is addressed from the tooth surface side and extends along the nipping transport path. That is, each traveling guide 28 is also twisted 90 ° along the corresponding timing belt 26. Each traveling guide 28 is supported on the above-described frame side.

The pulley shaft 30 of each power pulley 18 extends downward, and the lower ends of these pulley shafts 30 are rotatably supported by the frame. A gear 32 is provided at the lower end of the pulley shaft 30.
Are attached, and these gears 32 mesh with each other. Further, a torque motor 34 is disposed below one of the gears 32.
4 is also supported by the frame. Torque motor 34
Has an output shaft 36 protruding upward, and a gear 38 that meshes with one of the gears 32 described above is attached to the tip of the output shaft 36.

When the torque motor 34 is driven, the driving force is transmitted from the gear 38 of the output shaft 36 to the pair of gears 32, causing the pair of power pulleys 18 to rotate in opposite directions. The belt 26 runs synchronously. That is, a pair of gears 3
2 constitutes a drive mechanism (drive means) for the pair of timing belts 26. The supply voltage of the torque motor 34 is controlled in accordance with the load torque.

According to the supply posture changing device described above, the carbon rod C supplied by the presser press is continuously guided into the nipping and transporting passage through the introduction port, and is synchronously driven by the pair of timing belts 26. Accordingly, the liquid is transferred in the holding transfer passage toward the discharge port. In this transfer process, the position of the carbon rod C is gradually changed according to the twist of the pair of timing belts 26, and as is clear from FIG. Take a standing posture at 90 °
Be changed.

Here, since the traveling guides 28 are respectively addressed to the pair of timing belts 26, the carbon rods C are positioned between the pair of timing belts 26 in the sandwiching transfer passage, as is apparent from FIG. With these elastic forces, it is possible to securely hold the carbon rod C, and further, no excessive force is applied to the carbon rod C. Therefore, the carbon rod C is transported in the nipping transport passage without being damaged by cracks, cracks or scratches, and its posture is stably changed.

When the inside of the sandwiching transfer passage is filled with the carbon rod C, the torque motor 34 is thereafter driven intermittently according to the peripheral speed of the dial 12 described above. That is, at the timing when the groove 14 of the dial 12 passes through the discharge port of the sandwiching transfer passage, the pair of timing belts 26 intermittently travel, and as a result, the carbon rod C is inserted into each groove 14 of the dial 12 from the discharge port. Are sequentially pushed in, whereby the dial 12 can intermittently take out the carbon rods C from the inside of the sandwiching transfer passage and supply them to the main supply line described above. As a result, only the non-defective carbon rods C are continuously and stably supplied to the main supply line, and the production rate of the cylindrical manganese battery can be greatly improved.

The pair of timing belts 26 run exactly following the drive of the torque motor 34, and the supply voltage of the torque motor 34 is controlled in accordance with the load torque as described above. The traveling of the pair of timing belts 26 and the transfer of the carbon rods C in the sandwiching transfer passage can be accurately synchronized, and no slippage occurs between the timing belts 26 and the carbon rods C. Therefore, the pair of timing belts 26 do not receive wear from the carbon rod C,
The durability of these timing belts 26 can be sufficiently ensured.

The present invention is not limited to the embodiment described above, and various modifications are possible. For example, in one embodiment, the pair of timing belts 26 are twisted by 90 °, but the twist angle can be arbitrarily set according to the posture change angle required for the carbon rod C. Also,
It is needless to say that the present invention is not limited to the carbon rod C of the cylindrical manganese battery, but can be applied to changing the posture of various rod members.

[0028]

As described above, according to the rod member supply posture changing apparatus of the first aspect, the rod member is sandwiched between a pair of endless belts twisted at a predetermined angle, and the endless belt is rotated. With a simple configuration in which the rod member is transported along with the traveling of the vehicle, the posture of the rod member can be stably changed without damaging the rod member, and the continuous supply thereof can be ensured.

According to the supply posture changing device of the second aspect, since the pair of endless belts are guided by the traveling guide, the rod member can be stably sandwiched between the pair of endless belts, and There is no such thing as applying force. According to the supply posture changing device of the third aspect, since the timing belt is employed for the pair of endless belts, the running of the timing belt and the transfer of the rod member can be easily synchronized, and the timing belt is worn. And the durability can be improved.
