DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an automated method for continuously winding a non-adhesive long tape or a wide film such as an ink ribbon used for a thermal transfer printer or a typewriter on a core. The winding method.

[0002]

2. Description of the Related Art In order to wind a non-adhesive long tape body such as an ink ribbon around a core, the tip of the tape must first be fixed to an empty core surface, and the winding is completed. When you do, cut the tape that comes in,
It is necessary to fix the end portion of the full core to the tape surface of the full core.

[0003] As a method of fixing the leading end of the tape body to the empty core surface, the leading end of the tape is inserted into a cut formed in the core in advance and fixed, or the leading end of the tape is adhered to the core surface with an adhesive tape. There is a method that is performed manually, such as fixing by hand. However, it is not a simple task to press the wide tape tip into the core notch and fix it exactly parallel to the notch. A trouble such as the core spinning out of the cut may occur.
Also, even when fixing with an adhesive tape, the adhesive tape must be thin so as not to feel the thickness.In addition, it must be adhered and fixed exactly parallel so that the tape does not meander, and from the viewpoint of work efficiency There was also a problem.

On the other hand, a method is also known in which the leading end of the tape is automatically bonded and fixed to the empty core surface. JP-A-63-101
No. 250 discloses that an adhesive member is fixed on an empty core in advance and arranged at a winding position, and a web surface connected to a preceding full core is pressed against the adhesive member on the empty core to adhere. Fixed,
A method of cutting a web in the vicinity of a web traveling direction from an end portion of the adhesive member on the full core side is described.

According to this method, there is an advantage that an extra web piece is not generated at the leading end portion of the web on the empty core, but since the adhesive member is arranged on the empty core surface in advance, the winding is performed. Means are required for positioning the adhesive member surface of the empty core transferred to the take-up position so as to correctly face the web surface, and the winding web end portion on the fully-wound core side is fully filled. Means for fixing to the web surface of the wound core must also be provided separately.

[0006] Japanese Patent Publication No. 2-38504 discloses a method of winding a film around an empty bobbin prior to winding, in order to wind a film on an empty bobbin. That is, the adhesive surface is arranged at intervals having a length capable of winding the film around the bobbin several times, and by cutting the film within the adhesive surface, the film having the above-mentioned length having the adhesive surfaces at both ends is cut. A method for forming a film-coated bobbin for winding is described, in which one end is adhesively fixed to an empty bobbin surface and wound around a bobbin several times, and the other end is adhesively fixed to a wound film surface. I have.

This method is for making a bobbin coated by winding a film several times for winding, and therefore, an adhesive surface-applying film in which the adhesive surfaces are arranged on the film at predetermined equal intervals. It is not suitable as a method of manufacturing a tape having a large number of windings such as an ink ribbon since the winding is used, and the number of windings, that is, the length of the winding tape is different. It is also difficult to apply as a method of manufacturing a roll of tape.

[0008]

SUMMARY OF THE INVENTION The present invention provides an automated method and apparatus for continuously producing long, non-tacky webs of tape such as ink ribbons. The purpose is to do so. Another object of the present invention is to provide an automated winding method that can immediately cope with continuous production of tape bodies having different winding lengths.

[0009]

To achieve the above object, the method of the present invention is as follows. (1) A tape body fed from a non-adhesive tape body supply device is fully wound around an empty core at a tape body winding position. (2) Detecting that the core at the winding position is full, stopping the winding, and subsequently collecting the full core while pulling out the tape from the tape supply device. (3) moving the empty core in the standby position to the winding position, and (3) detecting that the tape body withdrawal amount has reached a preset amount in the middle of the preceding process At a position on the side of the tape supply device from the winding position, a pressure-sensitive adhesive having a predetermined length in the longitudinal direction by a pressure-sensitive adhesive layer supply means from a double-sided pressure-sensitive adhesive tape to a tape pulled out along with the movement of the full core. Transferring the layer,
(4) A state in which the arrangement of the full core and the empty core in the predetermined position is detected, the tape cutting means is operated, and the tape body portion having the adhesive layer is in contact with the empty core surface arranged at the winding position. Cutting off the full core side end and bonding the other end to the empty core surface, and (5) cutting the full core side end in conjunction with the cutting operation of the tape body at the winding position. Winding the part around the full core and bonding and fixing the same at the same time as starting the winding to the empty core where the other end of the cut tape body is adhesively fixed at the winding position. This is a method for winding a non-adhesive tape body.

[0010] The step (1) in the method of the present invention comprises:
Usually, a plurality of empty cores arranged at equal intervals on a turret rotating in a counterclockwise direction are sequentially moved to the winding position and arranged, and the fully-wound core which is fully wound at the winding position is taken up by the winding position. This is done using a device that is configured to be able to be collected at a collection location adjacent to the device.

An example of a means for detecting that the core at the winding position in the winding position in the step (2) is in a full winding state is an appropriate guide roller which is sent out from the tape body supply device and is moving to the winding position. The number of rotations of the roller is counted by the connected rotary encoder. When the rotary encoder detects that the rotation speed has reached a preset value, the winding to the core at the winding position on the turret is stopped by a command from the counter,
Turret rotation starts. The rotation of the turret is stopped by a limit switch or the like that detects that the full core on the turret is located at the collection position, and that the idle core in standby is located at the winding position.

The means for detecting the amount of tape pulled out in the step (3) is a rotary encoder similar to that in the normal step (2). The pressure-sensitive adhesive layer supply means is a means for supplying a non-supporting pressure-sensitive adhesive layer from the double-sided pressure-sensitive adhesive tape to the non-pressure-sensitive adhesive tape body, and a command from a counter based on a signal indicating that the winding operation at the winding position has been completed. A non-supporting pressure-sensitive adhesive layer is pressed from a double-sided pressure-sensitive adhesive tape surface onto a winding tape body by a press roll attached to a tip end portion of a cylinder that moves forward and backward, thereby transferring the pressure-sensitive adhesive layer.

The operation of the cutting means in the step (4) can be performed by a cylinder operated by the limit switch provided on the turret. Alternatively, the fact that the feed amount of the tape body has reached a preset amount may be detected by a rotary encoder, and the means may be operated by a command from a counter. In the step (5), the winding of the end to the full winding core at the collecting position can be performed by a winding motor driving mechanism at the collecting position connected to the limit switch, and the end is bonded and fixed. Is performed by driving a press roller which moves forward and backward by a cylinder provided at a collecting position.

In the method of the present invention, when the full core is moved to the recovery position, the pressure-sensitive adhesive layer applied to the tape body portion drawn from the tape supply device at a position closer to the tape supply device than the winding position. However, at the winding position, the winding core is controlled so as to be in direct contact with an empty core which is moved and arranged at the position instead of the full winding core.

As described above, since the pressure-sensitive adhesive layer of the tape body is in contact with the empty core surface at the winding position, the cutting device arranged outside the turret at the winding position is operated to move the cutting blade to the empty core. When the tape body having the pressure-sensitive adhesive layer in the direction is pressed and cut from the back surface, the end of the fully-wound core is cut off as the end of the fully-wound core, and at the same time, the other end is formed on the empty core surface by the adhesive layer. It is bonded and fixed to form the starting end of the empty core. Therefore, the winding to the empty core can be started immediately after the cutting operation, and the winding of the tape body can be automatically performed without stopping the apparatus.

Pre taking-up quantity of the tape member T ₁ of the the core 1 which is input to the counter by detecting the rotational speed of the guide roll 10 by the rotary encoder, corresponding to the feed amount of the tape member T ₁ of the core 1 is fully wound state When the rotation speed of the guide roll 10 reaches the previously set rotation speed, the winding of the winding core 1 is stopped by a command from the counter, and the rotation of the turret 4 is started.

As shown in FIG. 2, when the turret 4 starts to rotate counterclockwise, the tape body T ₁ is pulled by the full-wound core 1 and pulled out from the supply device of the tape body T ₁ .
When the rotary encoder detects that the tape body T ₁ has been pulled out by the preset length l ₁ , the cylinder 7 operates according to a command from the counter, and the pressure of the double-sided adhesive tape T ₂ is caused by the press roll 5. The agent layer is pressed against the non-adhesive tape body T ₁ and sandwiched between the receiving roll 6 and the motor M is driven, and the release paper take-up reel 9 starts winding the release paper. By this winding, the double-sided pressure-sensitive adhesive tape T ₂ moves at the same speed as the tape body T ₁ while transferring the non-supported pressure-sensitive adhesive layer to the tape body T ₁ , and only the release paper portion is wound around the reel 9. Taken.

As shown in FIG. 3, when the rotary encoder detects that the pressure-sensitive adhesive layer has been transferred to the take-up tape body T ₁ by the set length l _{2 based on the} number of rotations of the guide roll 10, the counter from the counter turns on. cylinder 7 by a command retracts the press roll 5, a double-sided adhesive tape T ₂ is separated from the tape body T ₁ side stops the winding operation by the reel 9 to stop the motor M at the same time. This supply of double-sided adhesive tape T ₂ is also stopped.

The turret continues to rotate, and when the empty core 2 following the full core is set to the winding position, the turret is stopped by a limit switch (not shown). During this time, the transferred portion of the tape member T ₁ of the adhesive layer is also pulled along with the movement of the fully wound core to move the winding position empty core 2 is fit to be set in the winding position, empty Stop in contact with the core surface.

When the pressure-sensitive adhesive layer of the take-up tape body T ₁ is stopped in contact with the empty core 2, the turret 4 is also stopped, and then, as shown in FIG. pressed against the empty core surface winding tape body T ₁ from the back surface having a material layer t _1, the length of l ₃ from fully wound core side sections adhesive layer l ₂ shown in FIG. 3 (a tape supply apparatus side retracts by cutting the tape body T ₁ at a point l the length of _4).

As shown in FIGS. 4 and 5, the cut end of the tape body T ₁ supply device side is adhered and fixed to the surface of the empty core 2 by an adhesive layer to form a winding tip. The winding around the empty core 2 is started in conjunction with the retreating operation of the cutting blade. The cut end on the full core 1 side is cut off and wound by the rotation of the full core 1 that operates in conjunction with the operation of the cutting blade, and the cylinder 16 that also operates in conjunction with the operation of the cutting blade reciprocates. The full roll core 1 is adhered and fixed on the full roll core 1 by the touch roll 14, and the winding of the full roll core 1 is also stopped. Cutting position in the adhesive layer interval is appropriately set by the value of l ₃ and l _4.

The non-stick winding operation of the tape member T ₁ of the to the core 1 by the above series of operations is terminated, the series of operations are started and the winding to an empty core 2 is repeated. The full core is collected and replaced at the turret collection position with a new core. In the above embodiment, the press roll 5

Further, transfer of the pressure-sensitive adhesive layer of the tape member T ₁ is the widthwise ends of the tape member T ₁ spaced a constant width, can also be carried out so as to provide only the center the longitudinal direction of, such When this is done, knob portions to which no pressure-sensitive adhesive layer is applied are formed on both sides of the end of the fully-wound tape, which is convenient for peeling off the end when the tape is used.

[0026]

As described above in detail, according to the tape winding method of the present invention, the winding start of the tape around the empty core and the ending of the winding of the tape around the fully wound core are as follows. At the same time, the adhesive layer can be formed, and the fixing process of the formed winding start and winding end ends can be automatically performed. Further, since the application of the pressure-sensitive adhesive layer is performed by transferring the non-supporting pressure-sensitive adhesive layer using a double-sided pressure-sensitive adhesive tape, a cutting device for the pressure-sensitive adhesive layer is unnecessary, and the operation of applying the pressure-sensitive adhesive layer is simplified. Can be

Further, by changing the values of l ₁ , l ₂ , l ₃ and l ₄ which define the length of the pressure-sensitive adhesive layer at both ends at the start and end of winding, the length of the pressure-sensitive adhesive layer at both ends is changed. There is an advantage that the adjustment can be made arbitrarily. Also,
The formation of the tape body start end and end by the adhesive layer transfer is performed by detecting the full winding state of the core at the winding position. It is a method that can respond.
