4 to 6 for a series of operations of the electrode foil 1 in the apparatus for connecting the electrode foil 1 and the external lead wire 2 used in the conventional aluminum electrolytic capacitor configured as above. It demonstrates using. First, as shown in FIG. 4, the wound electrode foil 1 is attached to a device (not shown), and one end of the wound electrode foil 1 is between the feed rollers 3 and 4 for feeding the electrode foil 1. And wound around a tension roller 8 to generate tension on the electrode foil 1, and thereafter, the electrode foil 1 is prevented from meandering.
The electrode foil 1 is wound around the groove formed on the outer peripheral surface of the guide roller 12. After this, one end of the electrode foil 1 is a detailed view of the constant tension generator C of FIG. 4 via the portion connecting the electrode foil 1 and the external lead wire 2 shown in the connection portion B of FIG. The electrode foil 1 shown in FIG. 6 is sandwiched between feed rollers 13 and 14 for intermittently feeding, and wound around a tension roller 17 to generate tension in the electrode foil 1, and thereafter the electrode foil 1 meanders. In order not to do so, the electrode foil 1 is wound around the outer peripheral surface of the guide roller 23, and then the electrode foil 1 is wound around the winding drum 22 shown in FIG.

In the above operation, the connection between the electrode foil 1 and the external lead wire 2 shown in the connection portion B of FIG. 4 is performed intermittently at a constant interval by the equipment tact. That is, while the electrode foil 1 and the external lead wire 2 are being connected, the electrode foil 1 is in a stopped state, and when the connection is completed, the feed roller 13 shown in FIGS. , 14, the electrode foil 1 is intermittently sent out. When the electrode foil 1 is sequentially fed, the electrode foil 1 shown in FIG. 5 is sequentially fed in the direction of arrow a. In this case, the tension roller 8 shown in FIG. 5 moves upward while being pulled by the electrode foil 1, and at the position b, the shield plate 9 arranged on the slide block 7 to which the tension roller 8 is attached. Shields the upper optical sensor 10. When the optical sensor 10 above this is shielded, the signal from this shield causes the motor 5 shown in FIG. 5 to rotate,
Then, the one feed roller 3 directly connected to the rotating shaft of the motor 5 rotates in the direction of arrow c. That is, the electrode foil 1 sandwiched between the one feed roller 3 and the other freely rotating feed roller 4 is fed in the direction of the arrow d. Further, the feed speed of the electrode foil 1 by the rotation of the motor 5 is always a little higher than the feed speed of the electrode foil 1 which is intermittently fed to an arbitrary size by the feed rollers 13 and 14 shown in FIG. Therefore, the guide roller 12 and the feed roller 3 shown in FIG.
The length of the electrode foil 1 between the four gradually increases. Then, as the length of the electrode foil 1 gradually increases, the tension roller 8 moves downward, and when it reaches the position of e in FIG. 5, the tension roller 8 is attached to the slide block 7. The provided shielding plate 9 shields the optical sensor 11 below. By the signal due to this shielding,
The rotation of the motor 5 shown in (3) stops and the feeding of the electrode foil 1 stops. As described above, as an important function in addition to the delivery control of the electrode foil 1 described with reference to FIG. 5, a constant tension is applied to the electrode foil 1 by the weight of the slide block 7 and the tension roller 8 as shown in FIG. It is a thing.

Next, the detailed operation of the constant tension generator C shown in FIG. 4 will be described with reference to FIG. As shown in FIG. 6, the electrode foil 1 sandwiched between the feed rollers 13 and 14 is sequentially fed in the direction of arrow a by the rotation of the motor 15. Along with that, the tension roller 18 shown in FIG. 6 moves downward, and at the position of f, the tension roller 18
A shield plate 19 arranged on the slide block 17 to which the is attached shields the optical sensor 21 below. When the optical sensor 21 below this is shielded, the signal due to this shielding causes the winding of the winding drum 22 shown in FIG. 4 for winding the electrode foil 1 with the external lead wire 2 connected thereto. . In this case, the winding speed of the winding drum 22 that winds the electrode foil 1 is slightly higher than the feeding speed of the electrode foil 1 sent by the feeding roller 13 that intermittently feeds the electrode foil 1 shown in FIG. When the winding drum 22 for winding the electrode foil 1 shown in FIG. 4 rotates, the tension roller 18 shown in FIG. 6 gradually starts moving upward.
When the slide block 17 reaches the position g in FIG. 6, the shield plate 1 arranged on the slide block 17
9 shields the upper optical sensor 20, and the signal from the shielding of the upper optical sensor 20 winds the electrode foil 1 with the external lead wire 2 connected to the winding drum 22 shown in FIG. The rotation is set to stop. As described above, as an important function in addition to the winding control of the electrode foil 1 described in FIGS. 4 and 6, a constant tension is applied to the electrode foil 1 by the weight of the slide block 17 and the tension roller 18 as shown in FIG. It is what you are giving.

[0009]

However, in the constant tension generator for a strip-shaped body such as an electrode foil used in the above-mentioned conventional aluminum electrolytic capacitor, the constant tension generator shown in FIG. Feed roller 1 at C
As the feeding speed of the electrode foil 1 by 3, 14 becomes faster,
In the state of the constant tension generator A, as shown in FIG. 7, the electrode foil 1 is fed intermittently. Therefore, when the electrode foil 1 is instantly pulled in the direction of the arrow a, , A large tension is applied to instantly move the stationary slide block 7, and when the tension becomes larger than the tensile strength of the electrode foil 1, the electrode foil 1 is cut off, which causes the original state. There was a problem that equipment loss for a long period of time would occur before it was restored to the above. Even if the electrode foil 1 is not cut, at the moment when the electrode foil 1 has been fed at high speed, the slide block 7 jumps up in the direction of the arrow h due to inertia, and the gap between the electrode foil 1 and the tension roller 8 is reached. There is a gap. That is, at the moment when the electrode foil 1 is fed at high speed, the tension applied to the electrode foil 1 temporarily becomes zero, which causes slack in the electrode foil 1 as shown by the arrow i in FIG. , And when connecting the electrode foil 1 and the external lead wire 2 at the connection portion B in FIG.
There was a problem that connection failure occurred.

The present invention solves the above-mentioned problems of the prior art, and is intended to reduce the width of strips such as electrode foils used in aluminum electrolytic capacitors and to speed up production equipment, the electrode foils, etc. It is an object of the present invention to provide a constant tension generating device for a belt-like body, which does not cause defective cutting of the belt-like body and can always apply a constant tension to the belt-like body to perform stable processing.

[0011]

In order to achieve the above object, a constant tension generator for a strip according to the present invention comprises a wound strip, a feed roller for delivering the strip, and a processing of the strip. And a control unit that is located between the processing unit and the feed roller, and that controls the feed roller and that keeps the tension of the belt-shaped body in the processing unit constant. The storage unit for storing the band-shaped body located between the feed roller and the processing unit, and the suction device for sucking air in the storage unit and pulling the band-shaped body are configured. , A constant tension can always be generated in the band by the flow of air by the action of the suction device. In this case,
A belt-shaped body such as an electrode foil that is intermittently fed at a high speed generates only tension fluctuations due to inertial fluctuations caused by the mass of the electrode foil, so the tension fluctuations generated in this band-shaped body can be made extremely small. As a result, even if the production equipment is speeded up or the width of the strip is narrowed, the cutting failure that the strip is cut during the operation of the production equipment and the production equipment is stopped as in the past does not occur. It will disappear.

Further, since a constant tension can always be generated in the strip by the flow of air, even if the feeding of the strip is stopped instantaneously, the inertia caused by the weight of the slide block or the tension roller as in the conventional case is generated. Then, there is no problem that the slide block or tension roller jumps up and the tension on the band disappears momentarily, and the band vibrates or meanders and a processing error occurs in the next process. Even if the strip is made narrower or the production equipment speeds up, the strips such as the electrode foil will not cause cutting failure, and a constant tension is always applied to the strip to perform stable processing. It has an excellent effect that it can be done.

A constant tension can always be generated by the flow of air due to the action of the suction device. In this case, the belt-like body such as the electrode foil that is intermittently fed at high speed is caused by the inertia fluctuation caused by the mass of the electrode foil or the like. Only tension fluctuation Since it does not occur, it is possible to make the fluctuation in tension generated in this strip very small, and as a result, even if the production equipment is speeded up or the strip is narrowed, the strip does not become It is possible to eliminate the disconnection failure that is caused by the cutting of the production equipment while the production equipment is in operation.

As shown in FIG. 1, the wound electrode foil 31 is attached to a device (not shown), and one end of the wound electrode foil 31 is sandwiched between feed rollers 33 and 34 for feeding the electrode foil 31. Then, the electrode foil 31 is hung in the box-shaped storage portion 37 to generate tension in the electrode foil 31, and thereafter, the guide roller 43 is arranged so that the electrode foil 31 does not meander.
The electrode foil 31 is wound around the groove formed on the outer peripheral surface of the roller. After that, one end of the electrode foil 31 is a detailed view of the constant tension generator C of FIG. 1 via the portion connecting the electrode foil 31 and the external lead wire 32 shown in the connection portion B of FIG. The electrode foil 31 shown in FIG. 3 is sandwiched between feed rollers 44 and 45 that intermittently feed the electrode foil 31, and the electrode foil 31 is hung in a box-shaped storage portion 48 to generate tension in the electrode foil 31. After that, the electrode foil 31 is wound around the outer peripheral surface of the guide roller 56 so that the electrode foil 31 does not meander, and then the electrode foil 31 is wound around the winding drum 54 shown in FIG. Is.

In the above operation, the connection between the electrode foil 31 and the external lead wire 32 shown in the connection portion B of FIG. 1 is performed intermittently at a constant interval by the equipment tact. That is, while the electrode foil 31 and the external lead wire 32 are being connected, the electrode foil 31 is in a stopped state, and when the connection is completed, the feed roller 44 shown in FIGS. , 45, the electrode foil 31 is delivered intermittently. When the electrode foils 31 are sequentially sent out, as shown in FIG.
The electrode foil 31 shown in is sent in order in the direction of arrow a.
In this case, the electrode foil 31 shown in FIG. 2 has a box-shaped storage portion 37 for generating a constant tension in the electrode foil 31 and a transparent lid 37a.
And a pair of optical sensors 39, which are arranged at a position b, which is opposed to above the side surface of the box-shaped storage portion 37, while being moved downward while being sucked by the air flow.
40 becomes a light receiving state. The signal due to this light reception causes the motor 35 shown in FIG. 2 to rotate in the direction of arrow c. That is, the electrode foil 31 sandwiched between the one feed roller 33 and the other freely rotating feed roller 34 is fed in the direction of the arrow d. Further, the foil feeding speed of the electrode foil 31 due to the rotation of the motor 35 is always a little higher than the feeding speed of the electrode foil 31 which is intermittently fed to an arbitrary size by the feeding rollers 44 and 45 shown in FIG. Therefore, the length of the electrode foil 31 between the guide roller 43 and the feed rollers 33 and 34 shown in FIG. 2 gradually increases. As the length of the electrode foil 31 gradually increases, the electrode foil 31 is stored in the box-shaped storage portion 37.

As shown in FIG. 3, the electrode foil 31 sandwiched between the feed rollers 44 and 45 is sequentially fed in the direction of arrow a by the rotation of the motor 46.

The electrode foil 31 moves while being sucked, and at the position b, shields the pair of photosensors 52 and 53 arranged at a position facing below the side surface of the box-shaped storage portion 48. The signal from this shielding causes the winding drum 54 shown in FIG. 1 for winding the electrode foil 31 to which the external lead wire 32 is connected to start rotating. In this case, the winding speed of the winding drum 54 for winding the electrode foil 31 is as shown in FIG.

Since the feeding speed of the electrode foil 31 is slightly higher than the feeding speed of the electrode foil 31, the rotation of the winding drum 54 for winding the electrode foil 31 shown in FIG.
5 and the length of the electrode foil 31 between the guide roller 56 are gradually shortened. Then, as the length of the electrode foil 31 is gradually shortened, the pair of optical sensors 50 and 51 arranged at a position facing the upper side of the side surface of the box-shaped storage portion 48 are in a light receiving state. The rotation of the winding drum 54 that winds up the electrode foil 31 shown in FIG. 1 is stopped by the signal from the received light. In this way, as an important function in addition to the winding control of the electrode foil 31 described in FIGS. 1 and 3,
As shown in FIG. 3, by sucking the air in the box-shaped storage section 48, a constant tension is always applied to the electrode foil 31 located in the storage section 48.

The belt-shaped body is configured by a storage unit that stores the belt-shaped body and a suction device that sucks air in the storage unit and pulls the belt-shaped body. A constant tension can always be generated by the flow of air.In this case, the belt-shaped body such as electrode foil that is intermittently fed at high speed,
Since only the tension fluctuations caused by the mass of the electrode foil etc. are generated, the tension fluctuations generated in this strip can be made extremely small, resulting in the speeding up of production equipment and the narrowing of the strip. Even in this case, it is possible to prevent the occurrence of a cutting failure such that the strip is cut during the operation of the production facility and the production facility is stopped as in the conventional case.

Further, since a constant tension can be always generated in the strip by the flow of air, even if the feeding of the strip is stopped instantaneously, inertia caused by the weight of the slide block or the tension roller as in the conventional case is generated. Then, there is no problem that the slide block or tension roller jumps up and the tension on the band disappears momentarily, and the band vibrates or meanders and a processing error occurs in the next process. Even if the strip is made narrower or the production equipment speeds up, the strips such as the electrode foil will not cause cutting failure, and a constant tension is always applied to the strip to perform stable processing. It has an excellent effect that it can be done.
