DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for winding a tape wound on a tape reel in a tape cartridge or the like.

[0002]

2. Description of the Related Art As a tape cartridge, there is a data cartridge used by being mounted on a recording / reproducing apparatus connected to a personal computer, an office computer, or the like. This data cartridge, for example, sucks up data signals stored in a memory or the like of a computer main body and records the data signals on a tape-shaped recording medium such as a magnetic tape.
Alternatively, the data signal recorded on the tape-shaped recording medium is supplied to a memory or the like of the computer main body.

[0003] This data cartridge is generally described as follows.
A cartridge body formed by combining a cover formed in a substantially shallow dish shape and a base plate formed of a metal plate such as an aluminum plate, a pair of tape reels rotatably arranged in the cartridge body, and a tape reel. The magnetic tape is provided with a magnetic tape wound around and wound around, and a drive belt in contact with the outer peripheral surface of the magnetic tape wound around the tape reel. This drive belt is formed of a band-like elastic material in an annular shape, and is stretched over a drive roller and a guide roller via a space between a pair of tape reels.

In the data cartridge constructed as described above, when the data cartridge is loaded in the recording / reproducing apparatus, the driving roller is driven to rotate by the recording / reproducing apparatus, so that the driving belt runs. The drive belt is applied with a predetermined tension to the magnetic tape because the drive belt is wound with a predetermined tension and is in contact with the magnetic tape. Thus, when the drive belt runs, the tape reel is driven to rotate, and the magnetic tape can run.

Conventionally, such a data cartridge has been
It is manufactured in a manufacturing process as shown in FIG. This manufacturing process includes: a planting process 100 for erecting a spindle on which a tape reel or the like is mounted on a base plate; an assembling process 101 for assembling a tape reel, a driving roller, a guide roller, or the like to the spindle; A belt wrapping step 102 of wrapping the drive belt over the assembled drive roller and guide roller, and a tape winding step 103 of winding a magnetic tape around a tape reel by a winding device;
The method includes a cover attaching step 104 for attaching a cover on the base plate, and a retention step 105 for driving the magnetic tape wound around using a recording / reproducing device once.

Among them, in the tape winding step 103,
As shown in FIG. 11, a magnetic tape 110 is supplied to one tape reel 112A from a roll 111 on which a magnetic tape 110 mounted in a winding device is wound. Reel 112
It is wound around A. Then, one tape reel 112A
After the magnetic tape 110 is wound around the cover, a cover attaching step 1
In 04, the cover 114 and the like are attached to the base plate 113 as shown in FIG.

At this time, the driving belt 115 laid in the belt wrapping step 102 is
A, 112B and the drive roller 116, so that the magnetic tape 110 is in contact with the wound magnetic tape 110 with a predetermined pressing force. The belt length of the drive belt 115 is
Since the drive belt 115 is in contact with the magnetic tape 110, the length becomes longer as the magnetic tape 110 is wound. For this reason, the drive belt 115 is
As the is wound, the pressing force applied to the magnetic tape 110 increases.

In the wound magnetic tape 110,
The winding pressure changes according to the pressing force applied by the drive belt 115. Therefore, the magnetic tape 110 is wound so as to have different winding pressures at the start of winding and at the end of winding.

In the wound magnetic tape 110, if the winding pressure is different, the tape tension will be different. The difference in the tape tension is a difference in the contact pressure between the magnetic head and the magnetic tape 110 in the recording / reproducing apparatus. It is preferable that the contact pressure between the magnetic tape 110 and the magnetic head be uniform from the viewpoint of electromagnetic conversion characteristics. Therefore, the wound magnetic tape 110
It is necessary to make the winding pressure uniform from the start of winding to the end of winding to have a uniform tape tension.

For this reason, in the conventional manufacturing process, a retention step 105 for rewinding the wound magnetic tape 110 is performed. In this retention step 105,
This is performed by making the magnetic tape 110 wound around one of the tape reels 112A travel one reciprocation using a recording / reproducing apparatus. Thereby, the retention step 105
Is performed on a tape reel 112A.
Has a substantially uniform winding pressure on the inner peripheral side and the outer peripheral side. As a result, the magnetic tape 110 has a uniform tape tension and always runs at a desired contact pressure with respect to the magnetic head.

[0011]

In the above-described manufacturing process, the tape winding step 103 for winding the magnetic tape 110 requires accurate control of the winding pressure of the magnetic tape 110 to be wound. Because it was done under precise control. However, according to the above-described method of winding the magnetic tape 110, the magnetic tape 11 is attached to the tape reels 112A and 112B at the start of winding.
Since 0 is not wound, the belt length of the drive belt 115 is short. Therefore, in the conventional method, the pressing force of the drive belt 115 is small at the start of winding.

On the other hand, in the above-described tape winding step 103, the winding speed is increased from the speed at the start of winding and accelerated to a maximum speed at a predetermined acceleration. That is, in the tape winding step 103, the acceleration at the start of winding is relatively large.

However, as described above, when the winding of the magnetic tape 110 is started, the driving belt 115
Is small and the acceleration at the time of winding the magnetic tape 110 is relatively large, so that a slip may occur between the drive belt 115 and the magnetic tape 110 in some cases. Thus, the drive belt 115 and the magnetic tape 110
If a slip occurs between them, the magnetic tape 11
There was a problem that the winding pressure of 0 could not be accurately controlled.

To prevent the slip from occurring, the magnetic tape 110 wound around the tape reel 112A is used.
It is conceivable to reduce the acceleration of. However, when the acceleration is reduced in this manner, it takes a long time to wind a predetermined amount of the magnetic tape 110, and there is a problem that productivity is reduced.

Further, in the above-described manufacturing process, a retention step 10 for rewinding the magnetic tape 110 is performed.
Step 5 is a step performed to make the winding pressure uniform, and is a step with low productivity from the viewpoint of manufacturing time. That is, if the magnetic tape can be wound with a substantially uniform winding pressure in the tape winding step, the retention step 105 is an unnecessary step and can be omitted.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a tape winding method and a tape winding method capable of winding a tape while a driving belt presses the tape against a tape wound on a tape reel at a desired pressure. It is intended to provide a device.

[0017]

According to the present invention, there is provided a method for winding a tape body, comprising: a pair of tape reels on which a tape body is wound; A driving belt that is wound around a plurality of guide rollers so as to press the outer peripheral surface of the tape body wound around the pair of tape reels, and the pair of tape reels is driven to rotate by running the driving belt. When winding the tape body on the tape reel of the tape cartridge, when the tape body starts to be wound around the tape reel, the drive belt is elastically deformed to increase the belt length. A predetermined pressing force is applied to the tape body wound around the reel.

In the above-described method for winding a tape body according to the present invention, when winding the tape body is started, the belt length of the drive belt is increased and the tension of the drive belt is increased. Thus, in this method, at the start of winding of the tape body, the pressing force on the tape body wound around the tape reel is increased. For this reason, according to this method, the desired frictional resistance is generated between the tape body and the drive belt. Thus, the tape body is wound without causing a slip between the tape body and the drive belt. Therefore,
According to this method, the pressure at which the tape body is wound, that is, the winding pressure, is accurately controlled, and starts to be wound.

Further, in the tape winding method according to the present invention, the drive belt applies a substantially constant pressing force to the tape body from the start of winding of the tape body wound around the tape reel to the end of winding. It may be something to give.

In such a case, according to the method of the present invention, a substantially constant pressing force is applied to the tape wound on the tape reel from the start of winding of the tape to the end of winding. , The winding pressure of the wound tape body is
It becomes substantially uniform over the entire area. Therefore, in this case, there is no need for the retention step conventionally performed to make the winding pressure of the tape body uniform.

Further, the tape winding method according to the present invention may be such that the length of the drive belt is substantially constant from the start of winding of the tape to the end of winding.

In such a case, according to the method of the present invention, since the length of the drive belt is made substantially constant from the start of winding of the tape to the end of winding, the drive belt is mounted on the tape reel. This means that a substantially constant pressing force is applied to the entire area of the wound tape body. Therefore, in this case, the winding pressure of the tape body is substantially uniform over the entire area. Therefore, also in this case, there is no need for a retention step conventionally performed to equalize the winding pressure of the tape body.

On the other hand, a tape winding device according to the present invention comprises a pair of tape reels on which a tape body is wound, and a tape formed in an annular shape having elasticity and wound on a pair of tape reels. A drive belt that is stretched over a plurality of guide rollers so as to press the outer peripheral surface of the body, and a pair of tape reels is rotated by driving the drive belt. In the winding device for winding up, there is provided pushing means for changing a length dimension of the drive belt. Then, the winding device pushes the drive belt at least when the tape body starts to be wound around the tape reel and elastically deforms the drive belt to increase the length dimension. The pressure applied from the drive belt to the wound tape body is set to a predetermined magnitude.

The winding device for a tape body according to the present invention configured as described above, when starting to wind the tape body,
By increasing the length of the drive belt, the tension of the drive belt can be increased. Thereby, in this winding device, the pressing force on the tape body wound on the tape reel can be increased. Therefore, the tape winding device can generate a desired frictional resistance between the tape and the drive belt. This allows
In the tape winding device, the tape is wound without slipping between the tape and the drive belt.
Therefore, the winding device can start winding the tape while accurately controlling the pressure at which the tape is wound, that is, the winding pressure.

In the tape winding device according to the present invention, the pushing means makes the length of the drive belt substantially constant from the start to the end of the winding of the tape. Is also good.

In the tape winding device according to the present invention, a substantially constant pressing force is applied to the tape from the start to the end of the winding of the tape. The tape body can be wound so as to have a substantially uniform winding pressure across the tape body. Therefore, in this case, there is no need for the retention step conventionally performed to make the winding pressure of the tape body uniform.

Further, in this assembling step, the reflecting member 19 is assembled in the reflecting member mounting hole 27 formed in the base plate 3.

Next, as shown in FIG. 4, a belt hanging step is performed. In this belt hanging step, the drive belt 13 is wound around the belt drive roller 14 and the pair of guide roller pins 18A and 18B. At this time, the driving belt 1
3 is passed over the space between the first tape reel 11A and the second tape reel 11B.

Since the drive belt 13 is formed of an elastic material such as urethane rubber, the drive belt 13 presses the first tape reel 11A and the second tape reel 11B with a predetermined pressing force. That is, the drive belt 13
Applies a predetermined pressure to a first press contact portion 28A that presses against the first tape reel 11A and a second press contact portion 28B that presses against the second tape reel 11B.

Next, using a magnetic tape winding device 30 as shown in FIG. 5, a magnetic tape 10 is wound around the base plate 3 on which the drive belt 13 is wound. Is performed.

In this tape winding step, the base plate 3 around which the drive belt 13 is wound is wound in order to wind the magnetic tape 10 around the first tape reel 11A against which the drive belt 13 is pressed as described above. It is mounted on the device 30.

The winding device 30 has a mounting portion 31 for mounting the base plate 3 around which the drive belt 13 is stretched.
And a roll 32 around which the magnetic tape 10 is wound, and a plurality of traveling system rollers 33 and a tension roller 34 constituting a traveling system of the magnetic tape 10 supplied from the roll 32.
A control panel 35 for controlling the running of the magnetic tape 10, and a drive belt 1 for the mounted base plate 3.
And a pressing device 36 for pressing the pressing device 3. Further, the winding device 30 is provided with the vacuum chamber 3 in the middle of the traveling system.
7 is provided.

Further, the winding device 30 includes a first cleaning unit 38A and a second cleaning unit 38B in a path of a traveling system of the magnetic tape 10. Furthermore, the winding device 30 includes a cutter unit 39 that cuts the magnetic tape 10 after a predetermined amount of the magnetic tape 10 is wound.

In the winding device 30, the mounting section 31 includes a capstan roller 40 for driving the belt driving roller 14 to rotate. The capstan roller 40 is configured to be able to move in a controlled manner between a first position where it contacts the flange portion 17 of the belt drive roller 14 and a second position where it is separated from the belt drive roller 14.

Further, the winding device 30 includes a roll 3
The motor 41 includes a motor 41 that supplies the magnetic tape 10 wound around 2 to the traveling system, and a motor belt 42 that transmits the rotational force from the motor 41 to the roll 32.

Further, in the winding device 30, as shown in FIG. 6, the pushing device 36 has a cylinder portion 43 and a cylinder portion 43 having a diameter substantially equal to the inner diameter of the cylinder portion 43. Piston part 44 disposed in
And a roll part 46 that moves in conjunction with the piston part 44 via the arm part 45, and a control part 47 that controls the driving of the piston part 44. This control unit 47
The first tube 48 and the second tube 49 connected to the two space portions separated by the piston portion 44, and the first tube 48 and the second tube 4
9 is provided with an electromagnetic valve 50 for supplying and discharging air. The pushing device 36 includes an air compressor (not shown) connected to the first tube 48 and the second tube 49 via the electromagnetic valve 50.

In the tape winding step using the winding device 30 configured as described above, the driving belt 13
Is mounted on the base plate 3, and the first tape reel 11A assembled to the base plate 3
The end of the magnetic tape 10 pulled out of the roll 32 is sandwiched between the magnetic tape 10 and the drive belt 13. The magnetic tape 10
When pulled out from the roll 32, it is wound around with a predetermined tension being applied by the plurality of traveling system rollers 33 and the tension roller 34. And roll 34
The magnetic tape 10 pulled out of the first tape reel 11A and the drive belt 13 is wrapped from the guide pin 12B with the flange toward the guide pin 12A with the flange. At this time, the magnetic tape 1
0 is easily sandwiched between the first tape reel 11A and the drive belt 13 because the tape tension is loosened by the vacuum chamber 37.

Here, in the winding device 30, the drive belt 13 presses the magnetic tape 10 sandwiched between the first tape reel 11A and the drive belt 13 with a predetermined pressure by the pushing device 36. . The pushing device 36 is
By controlling the solenoid valve 50, air is supplied from a not-shown air compressor to the space via the first tube 48. As a result, the piston portion 44 is driven toward the base plate 3, and as shown by an arrow B in FIG.
The roller portion 46 linked to the piston portion 44 drives toward the base plate 3. Then, the roller unit 46 pushes the drive belt 13. As a result, the length of the drive belt 13 is increased, and accordingly, a large pressing force is applied to the magnetic tape 10.

Then, in this state, the winding device 30 moves the capstan roller 40 to the first position and makes it contact the belt driving roller 14. The belt drive roller 14 is rotated by the torque of the capstan roller 40 being transmitted, and causes the drive belt 13 to run. Thereby, the magnetic tape 10 is connected to the first tape reel 1.
The first tape reel 11A is wound around the first tape reel 11A with the end sandwiched between the drive belt 1A and the drive belt 13 as a base end.

At this time, in the winding device 30, at the start of winding of the magnetic tape 10, the acceleration of the rotation speed of the capstan roller 40 is large. Therefore, if the pressing force of the drive belt 13 against the magnetic tape 10 is small,
Slip occurs between the magnetic tape 10 and the drive belt 13, causing slip. However, in this winding device 30, the pushing device 36 is
, And the drive belt 13 applies a large pressing force to the magnetic tape 10. For this reason, if this winding device 30 is used, the magnetic tape 10 can be reliably transferred to the first tape reel 11 without the drive belt 13 idling.
A can be wound.

Also, from this, the winding device 30
In this case, since the friction between the drive belt 13 and the magnetic tape 10 increases, the acceleration at the start of winding the magnetic tape 10 can be increased. Therefore, in the winding device 30, the time required for the tape winding step can be reduced, and as a result, the productivity can be improved.

As described above, in addition to the rotational force of the capstan roller 40, the rotational force of the motor 41 is applied to the roll 32 via the motor belt 42.
The magnetic tape 10 is made to travel by the roll 32 sending out the magnetic tape 10 to the magnetic tape 10. At this time, the winding device 30 is connected to the first cleaning unit 38.
A cleans one surface of the magnetic tape 10 with A, and cleans the other surface of the magnetic tape 10 with the second cleaning unit 38B. The first cleaning unit 38A and the second cleaning unit 38B
Cleaning is performed by bringing the cleaning tape 53 into sliding contact with both surfaces of the magnetic tape 10.

Then, in the winding device 30, as the magnetic tape 10 is wound around the first tape reel 11A, the pressing force of the drive belt 13 increases. Therefore, when the drive belt 13 applies a predetermined pressing force to the magnetic tape 10, the pushing device 36 operates the drive belt 1.
Stop pushing 3. This is because the magnetic tape 10 wound around the first tape reel 11A can increase the length of the drive belt 13 without increasing the length of the drive belt 13 by the pushing device 36. is there.

At this time, in the pushing device 36, the air in the space is discharged through the first tube 48, and at the same time, the air is supplied from the air compressor to the space through the second tube 49. Accordingly, the piston portion 44 moves in a direction away from the base plate 3, and in conjunction with this, the roller portion 46 moves in a direction away from the base plate 3. Thus, the pressing device 36 stops pressing the drive belt 13.

In the winding device 30, the control panel 35 controls the amount of the magnetic tape 10 wound on the first tape reel 11A. The magnetic tape 10
When the predetermined amount has been wound around the first tape reel 11A,
It is cut by the cutter unit 39. Then, the end of the magnetic tape 10 cut and formed by the cutter unit 39 is sandwiched between the second tape reel 11B and the drive belt 13, as shown in FIG.

When the tape winding step is completed as described above, a cover attaching step (not shown) is performed. In the cover attaching step, the cover 2 and the cover member 6 are attached to the base plate 3 having the magnetic tape 10 wound as described above.
Attach. At this time, the cover 2 is securely attached to the base plate 3 by the set screw 3A. Also,
The cover member 6 is axially mounted on a cover member pin 7 and is urged in a predetermined direction by a torsion spring 8 to cover the cover 2.
And the base plate 3. Thereby, the data cartridge 1 is formed.

Next, although not shown, a retention step is performed on the data cartridge 1 thus formed. In the data cartridge 1, the tape tension of the magnetic tape 10 is a contact pressure with the magnetic head of the recording / reproducing apparatus, and is preferably substantially the same over the entire area of the magnetic tape. This retention step is a step of making the tape tension of the magnetic tape 10 wound around the first tape reel 11A uniform.

In this retention step, an ordinary recording / reproducing device is used. In this retention step, the data cartridge 1 is loaded into the recording / reproducing apparatus, the magnetic tape 10 wound around the first tape reel 11A is run, wound around the second tape reel 11B, and further, the second tape The magnetic tape 10 wound around the reel 11B is run and re-wound around the first tape reel 11A. By performing the retention step in this manner, the magnetic tape 10 wound on the first tape reel 11A has substantially the same tape tension over the entire area.

As described above, according to the manufacturing method to which the present invention is applied, as shown in Table 1, the tape body can be satisfactorily wound as compared with the case where the conventional manufacturing method is used. Was.

[0068]

[Table 1]

As is clear from Table 1, in the manufacturing method to which the present invention is applied, the fluctuation of the tape tension is small and the winding acceleration can be increased as compared with the conventional manufacturing method. Further, in the manufacturing method to which the present invention is applied,
Compared with the conventional manufacturing method, the time required for winding can be reduced, and the productivity can be improved.

In the above-described tape winding method and tape winding device, in the tape winding step, a predetermined pressing force is applied to the magnetic tape 10 when the magnetic tape 10 starts to be wound around the first tape reel 11A. Was. However, the present invention is not limited to this.

That is, the tape winding method and the tape winding device according to the present invention are configured such that a desired pressing force is always applied to the magnetic tape 10 in the tape winding step. Is also good. Specifically, in the tape winding step, it is preferable that substantially the same pressing force is applied over the entire area of the magnetic tape 10 to be wound.

For this purpose, as shown in FIG. 8, it is preferable to use a pushing device 56 having a regulator 55 as the winding device 30 used in the above-described tape winding process. The pushing device 56 is provided with the first tube 4.
8 is provided with a regulator 55 in the middle of the first tube 4.

Accordingly, the drive belt 13 can always apply substantially the same pressing force over the entire area of the magnetic tape 10 to be wound. As a result, the wound magnetic tape 10 has substantially the same tape tension from the start of winding to the end of winding.

The pushing device 61 configured as described above is
By controlling the driving of the roller driving motor 60 by the regulator 66, it is possible to control the pushing amount of the driving belt 13. In the pushing device 61, when the roller unit driving motor 60 rotates, the rotational force is applied to the support shaft 6.
2 and the support shaft 62 rotates as shown by the arrow C in FIG. The moving portion 63 is screwed with the support shaft 62 and is configured not to rotate in conjunction with the support shaft 62. Therefore, when the support shaft 62 rotates, the moving section 63 can move in a direction approaching or separating from the base plate 3 as shown by an arrow D in FIG.

The roller section 65 moves in conjunction with the moving section 63 which moves as described above. For this reason, in the pushing device 61, the roller unit 65 interlocked with the moving unit 63 presses or relaxes the drive belt 13. At this time, the pushing device 61
However, the pressing force on the magnetic tape 10 can be controlled by changing the belt length of the drive belt 13 in the same manner as the pressing devices 36 and 56 described above.

Therefore, even when the pressing device 61 is provided, a desired pressing force can be applied to the magnetic tape 10 at the start of winding the magnetic tape 10. Therefore, also in this case, the drive belt 13 and the magnetic tape 1
Therefore, the magnetic tape 10 can be wound around the drive belt 13 without idling.

In the pushing device 61, the moving distance of the roller unit 65 can be controlled by controlling the number of rotations and the rotation speed of the roller unit driving motor 60. Also in this case, similarly to the pushing device 56 described above, the roller portion 65 is moved in the direction in which the drive belt 13 is relaxed so as to cancel the increase in the belt length of the drive belt 13.
To move.

Therefore, even when the pushing device 61 is provided, the winding device 30 can apply a predetermined pressing force to the magnetic tape 10 from the start of winding of the magnetic tape 10 to the end of winding. Therefore, also in this case, the magnetic tape 10 is wound so as to have a substantially uniform tape tension over the entire area. Thus, also in this case, the above-described manufacturing process can be shortened without the need for the above-described retention process.

Note that the present invention is not limited to the data cartridge 1 having the magnetic tape 10 as described above. In the present invention, for example, a cleaning tape or the like may be provided as a tape body, and the tape body may have any flatness. That is, in the present invention, the same effect can be obtained by setting the pressing force of the drive belt to a predetermined magnitude in consideration of the surface properties of the tape body.

As described in detail above, in the method and apparatus for winding a tape body according to the present invention, the length of the drive belt is increased when the tape body starts to be wound on a tape reel. As a result, the drive belt applies a predetermined pressing force to the tape body. For this reason, according to the present invention, since the drive belt is driven without slipping when the winding of the tape body is started, the winding pressure of the tape body can be accurately controlled. Further, according to the present invention, since the drive belt presses the tape body with high pressure, the acceleration of the drive belt can be increased. Therefore,
According to the present invention, productivity can be improved.
