Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape winding device used for winding a tape into a coil when manufacturing a capacitor or a secondary battery. Here, the tape refers to a tape formed of a thin material regardless of the material, such as a metal foil or electrolytic paper in a capacitor, an electrode plate or a separator in a secondary battery, and the like.

[0002]

2. Description of the Related Art Various devices have been proposed to efficiently perform the above-described tape coil winding operation. For example, in Japanese Patent Application Laid-Open No. 9-315629, a plurality of winding shafts are provided on a winding shaft holder that rotates intermittently, and the winding shaft is sequentially intermittently rotated to a winding position, a taping position, and a takeout position. A capacitor element winding device that performs a taping and unloading operation while moving, a separating material on each winding shaft, a winding motor for winding an anode foil and a cathode foil, a wound separating material, An independent driving device for a taping motor for tape-taping the anode foil and the cathode foil, and a winding shaft moving motor for moving the winding shaft in the axial direction for taking out the capacitor element are provided. There is disclosed an apparatus provided with an intermittent rotation motor for intermittently rotating by a predetermined angle ("Prior Art 1").

According to the above construction, the mechanism is extremely complicated and the driving device of the winding shaft becomes large.
Japanese Patent No. 5629 discloses an apparatus in which the apparatus is greatly simplified and downsized ("Prior Art 2"). That is, a winding shaft holder that intermittently rotates around a rotation center of a sun gear rotated by the first driving device is provided, and a plurality of sun shafts are rotatably provided on the winding shaft holder. By configuring the planetary gear mechanism by fixing the planetary gears meshing with the gears respectively, by rotating the sun gear, a plurality of winding shafts can be synchronously rotated in the same direction. In addition, this eliminates the need for a driving device conventionally required for each winding shaft, and enables a plurality of winding shafts to be simultaneously rotated with only one driving device.

[0004]

As described in "Prior Art 1", if a winding motor, a taping motor, and a winding shaft moving motor are provided with independent driving devices for each winding shaft, a mechanism is required. And the drive of the winding shaft becomes large. On the other hand, the configuration of "Prior Art 2" opens the way to simplifying and compacting the apparatus, but also has the following problems.

That is, the respective winding shafts are always synchronously rotated in the same direction and at the same rotation speed by the same angle.
Usually, the winding operation is performed by rotating the shaft at high speed, but the taping operation is not performed at such high speed rotation. Regarding the number of rotations, the winding operation rotates the shaft many times, but the taping operation only rotates the shaft approximately once. When taking out the capacitor element, it is better that the shaft stops rotating.

As described above, the winding operation, taping operation and unloading operation cannot be performed simultaneously, and must be performed sequentially. For this reason, there has been a problem that high-speed and efficient work cannot be sufficiently achieved.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned problems, and an object of the present invention is to provide a turret for performing different kinds of operations by feeding a winding shaft at a fixed angle. The object of the present invention is to enable different types of work to be performed simultaneously in a mold type apparatus. At the same time, the mechanism for achieving this is to avoid being complicated as in "Prior Art 1".

In order to achieve the above object, according to the first aspect of the present invention, the tape winding device is provided with the following configuration. a. Turret b. A plurality of winding shafts each rotatably supported by the turret for winding the tape into a coil; c. A turret rotation motor for rotating the turret so that the winding shaft moves to a predetermined work station in sequence d. A winding shaft rotating motor provided outside the turret in a one-to-one correspondence with the winding shaft, for rotating the corresponding winding shaft independently of other winding shafts;

As described above, each winding shaft is rotated independently of the other winding shafts by the winding shaft rotating motor corresponding to the winding shaft on a one-to-one basis. A plurality of operations having different rotation speeds, number of rotations, and different start and stop timings can be simultaneously performed. Since the take-up shaft rotation motor is disposed outside the turret, the turret can be made compact and the turret structure does not need to be complicated.

According to a second aspect of the present invention, in the tape winding device according to the first aspect, each of the winding shafts is provided with a pinion, and each of the pinions has a one-to-one correspondence.
A plurality of internal gears connected in correspondence are supported by a turret, and a winding shaft rotating motor is connected to these internal gears in a one-to-one correspondence.

With this configuration, even if the number of winding shafts increases, it is possible to drive independently of other winding shafts by increasing the number of combinations of pinions and internal gears. The extension of the combination of the pinion and the internal gear can be realized by shifting the position in the axial direction and is easy.

It is another object of the present invention to provide a tape winding device capable of winding a coil having no slack or uneven thickness in a winding layer.

[0013] In order to achieve the above object, according to the third aspect of the present invention, the tape winding device is provided with the following configuration. a. Turret b. A winding shaft rotatably supported by the turret for winding the tape into a coil; c. A control device that controls the angle of the turret in accordance with the change in the diameter of the coil so that the tape entry angle with respect to the coil is constant.

[0014] With the above construction, the tape entry angle with respect to the coil is constant, and the tape entry angle is changed, so that it is possible to prevent slack and uneven thickness in the winding layer. This is particularly effective when different types of tapes are stacked and wound.

Next, the operation moves to the state shown in FIG. Here, first,
The clamp members 93, 94, 95, 96 are retracted. At this time, the negative foil tape 82 is

That is, as the diameter of the coil 120 increases, the turret 13 rotates clockwise so as to keep the angle of entry of the tape laminate 105 relative to the coil 120 constant, in the embodiment, substantially horizontal. This operation is performed through control of the turret rotation motor 14. This control will be described with reference to FIG.

When the winding operation is started for a specific type of capacitor, first in step S201, the control device 130 calculates the relationship between the winding length of the tape laminate 105 and the winding diameter of the coil 120. Since the thickness of the tape laminate 105 differs depending on the type of the capacitor, the calculation result also differs depending on the type of the capacitor.

Subsequently, in step S202, the coil 12
The relationship between the winding diameter of 0 and the angle of the turret 13 is calculated.

After the calculation in step S202, the read value of the reference encoder 110 is cleared to zero in step S203.

Subsequently, in step S204, rotation of the mandrel 25 located at the work station A is started. This is because the winding shaft 20 to which the mandrel 25 is attached is rotated by any of the winding shaft rotating motors 70, 71, 72 via any of the internal gears 61, 62, 63. Achieved.

In step S205, the reference encoder 11
Read the measured value of 0. The travel distance of the plus foil tape 83 is equal to the travel distance of the tape laminate 105, and thus the value measured by the reference encoder 110 is the travel distance of the tape laminate 105.

In step S206, the tape laminate 105
The winding diameter of the coil 120 is calculated from the travel distance of the coil 120, that is, the winding amount of the coil 120.

In step S207, the turret 13 is used to keep the tape stack 105 at a constant angle of entry into the coil 120.
Calculate the angle of.

In step S208, a command is issued from the control device 130 to the driver 131 of the turret rotation motor 14, and the turret 13 is moved to the angle calculated in step S13.

In step S209, it is checked whether or not the winding of the coil 120 has been completed. If not completed, the flow returns to step S205.

The operations from steps S205 to S209 are repeated every fixed distribution cycle. The distribution cycle is a short time in milliseconds.

As described above, the winding diameter of the coil 120 is checked based on the read value of the reference encoder 110, and the winding of the coil 120 is advanced while the angle of the turret 13 is changed correspondingly.

FIG. 12 shows a state in which the coil 120 has been wound up to a predetermined winding diameter.
5 stops rotation. Before reaching this point, the pinch roller 85, the guide roller 87, and the tape guide 88 are lowered, and the tape guide 88 simultaneously changes its inclination to the non-guide position.

Subsequently, the operation moves to the state shown in FIG. Here, the clamp members 93 and 94 approach to clamp the minus foil tape 82, the clamp members 95 and 96 approach to clamp the plus foil tape 83, and
0 and 101 approach and sandwich the minus foil tape 82, and the cutter members 102 and 103 approach and sandwich the plus foil tape 83.

Next, the operation moves to the state shown in FIG. Clamp member 9
3 and 94 are the clamping members 9 of the negative foil tape 82.
5 and 96 continue to clamp the plus foil tape 83, respectively, but the cutter members 100 and 101 and the cutter members 102 and 103 have already separated and returned to the normal state. Here, the turret 13 starts rotating, and the work station A
To the work station B, the coil 120 of the work station B to the work station C, and the mandrel 25 of the work station C to the work station A.

When the mandrel 25 of the work station C is moved to the work station A, the mandrel 25 is moved to the work station C by the lever 3 shown in FIG.
Since it is retracted at 4, it does not hit the chuck member 90 during the movement. Later, the mandrel 25 arrives at the work station A without interfering with the tape stack 105.

Coil 120 at work station A
On the way to the work station B, the chuck member 90 is lowered and the chuck member 91 is raised as shown in FIG. As a result, the tape laminate 105 is sandwiched, and at the same time, the cutter member 92 is raised, and the tape laminate 105 is sandwiched between the chuck member 90 and the chuck member 90.

By the above cutting, the tape laminate 105 is wound around the coil 120 and the chuck member 90,
It is divided into the part that is sandwiched between 91 and remains. In the case of the minus foil tape 82 and the plus foil tape 83, the cut ends when cut in FIG. 13 are completely wound around the coil 120, and the cut ends are electrolytic paper tapes 80 and 81.
The cutting position in FIG. 13 is adjusted so as to slightly wrap.

Next, the operation moves to the state shown in FIG. Here, the pinch rollers 84 and 85 sandwich the tape stack 105.

Coil 120 at work station A
Arrives at work station B. The mandrel 25 supporting this rotates while moving from the position of FIG. 15 to the work station B or even after arriving at the work station B, so that the tape laminate 105 is completely wound around the coil 120. The taping device 121 approaches the coil 120 and uses the adhesive tape to form the tape laminate 10.
Cut off the end of 5.

Coil 120 at work station B
Arrives at work station C. The take-out arm 122 approaches the coil 120 and chucks the coil with the hand unit. At the same time, the lever 34 (see FIG. 1) arranged at the work station C slides the winding shaft 20 to move the mandrel 25 to the ironing member 45 at the tip.
Retract until it hides inside. Due to the ironing member 45, the coil 120 cannot move following the mandrel 25, whereby the coil 120 separates from the mandrel 25 and remains in the hand portion of the take-out arm 122. The take-out arm 122 carries the coil 120 out of the turret 13 and arranges it on a pallet (not shown).

Mandrel 2 at work station C
5 arrives at work station A. This state is shown in FIG.
It corresponds to. In FIG. 17, the mandrel 25 is not shown to emphasize that the mandrel 25 is in the retracted position. After the arrival of mandrel 25,
A lever 33 (see FIG. 1) arranged at the work station A slides the winding shaft 20 to move the mandrel 25.
To the projected position. Then, the mandrel 25 is
As shown in FIG. 8, the tape laminate 105 is inserted into the slit 26. At this time, since the angle of the slit 26 must match the direction in which the tape laminate 105 is stretched, an encoder is combined with the winding shaft rotating motors 70, 71, and 72 to determine the angle of the winding shaft 20. , And you can control it.

At this time, the tip of the mandrel 25 is fitted into the end face recess of the mandrel receiver 46. As a result, the tip of the mandrel 25 does not move, and the coil 1 is smoothly moved.
We are ready to wind 20.

With the above, the state returns to the state of FIG. 6, and the cycle described above is repeated.

Focusing on the movement of the mandrel 25 located at the work stations A, B and C, the work stations A
After winding the end of the tape laminate 105, the mandrel 25 rotates at high speed and winds the coil 120. After winding the end of the tape laminate 105, the mandrel 25 of the work station B rotates in accordance with the taping device 121. The mandrel 25 of the work station C does not rotate. As described above, the rotation speed and the number of rotations required for the winding shaft 20 are completely different depending on the place and the work stage. However, in the configuration of the present invention, the winding shafts 20 can be rotated independently of each other. Different tasks can be performed simultaneously.

For the sake of convenience, the taping device 121 and the take-out arm 122 are shown only in FIG.
10 can be made to appear at any time in a state where the turret 13 is not moving.
Also, the work does not have to be completed within the time frame cut out in one diagram, but can be performed in a time frame spanning a plurality of diagrams.

In the illustrated embodiment, the winding shaft 20
Although the number is set to three, a configuration in which the number is two or a configuration in which the number is four or more is also possible.

The winding shaft rotating motors 70, 71,
The timing belt 74 is used to transmit rotation from the internal gear 72 to the internal gears 61, 62, 63. However, this is another type of rotation transmitting means capable of transmitting power without slip like the timing belt, for example, a gear. It is also possible to replace it with a chain or the like.

In addition, various changes can be made to the embodiment without departing from the spirit of the invention.

[0079]

According to the present invention, the following effects can be obtained. Each take-up shaft is rotated independently of the other take-up shafts by a take-up shaft rotating motor that corresponds to the take-up shaft on a one-to-one basis. A plurality of tasks having different start and stop timings can be simultaneously performed. Since the winding shaft rotating motor is arranged outside the turret, the turret can be made compact and the turret structure does not become complicated. Power supply and control to the winding shaft rotation motor are also easy. A pinion is provided for each of the winding shafts, and a plurality of internal gears connected to the pinions in a one-to-one correspondence are supported by a turret, and a winding shaft rotation motor is connected to these internal gears in a one-to-one correspondence. With this configuration, the take-up shaft can be rotated independently of the other take-up shafts. Even if the number of winding shafts increases, the number of combinations of pinions and internal gears can be increased. The extension of the combination of the pinion and the internal gear can be realized and easily realized by displacing the position in the axial direction. When winding the tape in the form of a coil with the winding shaft, the turret angle is controlled according to the change in the diameter of the coil so that the tape enters the coil at a constant angle. Therefore, it is possible to prevent sag and unevenness in thickness in the winding layer. This is particularly effective when winding different types of tapes one upon another.
