Description

  The present invention relates to a tape fabric manufacturing apparatus.

  Tape-like elongated fabric parts (hereinafter referred to as “tape fabric”) that are attached to clothing cuffs, collars, waists, etc. as trimming materials or tightening materials are knitted into a tubular fabric using a circular knitting machine. In some cases, it is manufactured by cutting out spirally from one end of the cylinder in accordance with the tape width (for example, see Patent Document 1). The tape dough producing apparatus used in carrying out this production method includes a drive rotor and a driven rotor projecting downward, and has a configuration in which one tube end of the tube dough is wound around both rotors. It was.

  In this tape dough producing apparatus, while rotating the drive rotor to rotate the tubular dough around its cylinder axis, a rotary blade is pressed against the outer peripheral surface of the tubular dough to cut out the tape dough. Note that the driven rotor can be adjusted in angle so that the rotor shaft is tilted obliquely, and the spirally tilted driven rotor gives a spiral upward rotational force to the cylindrical fabric. That is, every time the cylindrical fabric rotates, the cylindrical fabric rises along the cylinder axis, and this increased dimension corresponds to the tape width cut out by the rotary blade.

  In other words, by adjusting the angle of the driven rotor, the tape width of the tape fabric to be cut out is adjusted or changed.

JP-A-11-279932

  In conventional tape fabric manufacturing equipment, the tape width is adjusted or changed only by adjusting the angle of the driven rotor, but the dimensional accuracy variation is plus or minus 5 mm no matter how careful the angle adjustment is. To some extent, it existed. This became a bottleneck when trying to increase the yield for the tubular fabric, and the yield could not be sufficiently increased. Of course, the width accuracy of the tape fabric greatly affects the quality of clothing using the tape fabric.

  Further, when the cylindrical fabric wound around the drive rotor and the driven rotor is rotated around the cylindrical axis, the portion of the cylindrical fabric that hangs down from both rotors is twisted, and this twist is the cause. In some cases, the action of pulling the tubular fabric downward may occur. Needless to say, this effect adversely affects the tape width. In the first place, it has been difficult to set the tape width by adjusting the angle of the driven rotor, and skill adjustment is required for adjusting the angle of the driven rotor.

On the other hand, since this type of tape fabric manufacturing apparatus has a configuration in which the rotation speed of the rotary blade cannot be adjusted, it is a highly stretchable fabric (a fabric that is difficult to apply a tension that increases the cylinder diameter). In some cases, there has been a demand for improvement that it becomes difficult or impossible to cut out the tape fabric.
The present invention has been made in view of the above circumstances, it is possible to cut out the tape dough while maintaining the tape width with high accuracy, and the tape width can be changed easily and quickly, An object of the present invention is to provide a tape dough producing apparatus that can eliminate and eliminate various problems of the prior art.

The cutting unit includes a rotary blade that contacts the outer peripheral surface of the cylindrical fabric and a cutting motor that rotates the rotary blade, and the control unit is configured so that the peripheral speed of the rotary blade is the peripheral speed of the cylindrical fabric. It is preferable that the cutting motor is controlled so as to be faster.

It is preferable to do this.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 7 show an embodiment of a tape dough producing apparatus 1 according to the present invention. This tape fabric manufacturing apparatus 1 has a configuration in which a vertical frame 3 having a base portion 2 supports a head portion 4 to which one cylindrical end of the tubular fabric W can be mounted at a predetermined height. ing. The head portion 4 can rotate the cylindrical fabric W after being mounted around its cylindrical axis, and cut out the tape fabric T from the upper peripheral portion of the cylindrical fabric W while rotating the cylindrical fabric W. Be able to.

In the tape fabric manufacturing apparatus 1 according to the present invention, when the tubular fabric W is rotated (when the tape fabric T is cut out), the tubular fabric W is always in a tubular shape so that the upper peripheral portion of the tubular fabric W can maintain a constant height. The position control of the dough W is performed.
Hereinafter, the detailed structure of the tape fabric manufacturing apparatus 1 will be described.
The head portion 4 is provided with a plurality of rotors (three shown by reference numerals 7 to 9 in the illustrated example) so as to protrude obliquely downward, and surround the rotors (7 to 9). One cylindrical end of the cylindrical fabric W is wound and attached. The head portion 4 is provided with a cutting portion 12, a position adjusting mechanism 13, and a position detecting portion 14 in an arrangement corresponding to the upper peripheral portion of the attached tubular fabric W. On the other hand, the base portion 2 is provided with a fabric receiving base 15 for supporting a portion (the other cylinder end side) that hangs down in the installed cylindrical fabric W.

The tape fabric manufacturing apparatus 1 further controls each operation of the cutting unit 12, the position adjusting mechanism 13, and the fabric receiving base 15 according to the state of the cylindrical fabric W obtained from the position detecting unit 14 and the like. A control unit 16 is provided. The installation position of the control unit 16 is not particularly limited, but may be provided for the head unit 4 or the like.
First, the rotor (7-9) will be described.

  As shown in FIGS. 1, 2, and 4, the rotors (7-9) are provided with a first drive rotor 7, a second drive rotor 8, and a tension rotor 9, at least one of which is provided. It is designed to rotate. In the present embodiment, the first drive rotor 7 is rotationally driven by the rotor motor 20, and the second drive rotor 8 is rotationally driven by the rotor motor 21.

The speed ratios of the rotor motors 20 and 21 are set so that the rotation directions of the first drive rotor 7 and the second drive rotor 8 are the same and the peripheral speeds are matched. For the rotor motors 20 and 21, it is preferable to employ a control motor such as a stepping motor or a servo motor.
The first drive rotor 7 is formed to have the largest diameter compared to the other two rotors (second drive rotor 8 and tension rotor 9), and an elastic cover (not shown) such as urethane or rubber is provided on the outer peripheral surface thereof. ) Is pasted. By providing this elastic cover, it is possible to prevent the cylindrical fabric W to be worn from being scratched and to prevent slippage when transmitting the rotational force to the cylindrical fabric W.

The second drive rotor 8 is provided with the position adjusting mechanism 13 on the outer peripheral surface of the rotor. Details of the position adjusting mechanism 13 will be described later. Further, the second drive rotor 8 is provided with an angle adjusting mechanism 19 that allows the inclination angle of the second drive rotor 8 to be adjusted with a horizontal shaft 18 provided in the head portion 4 as a fulcrum.
This angle adjusting mechanism 19 is for adjusting the tape width of the tape fabric T cut out from the upper peripheral portion of the cylindrical fabric W. As shown in FIG. 7, the rotor shaft 8a (rotation) of the second drive rotor 8 is provided. Shaft) from a box-shaped joint case 22 provided for housing a joint portion (connection portion) between the motor shaft of the rotor motor 21 and both sides of the joint case 22 while being orthogonal to the rotor shaft 8a. Thus, the horizontal shaft 18 is protruded.

  The horizontal shaft 18 does not penetrate through the joint case 22 and is fixed to the joint case 22 so as not to rotate so as to protrude in opposite directions from both side surfaces of the joint case 22. Therefore, by rotating the horizontal shaft 18, the joint case 22 can be swung around the horizontal shaft 18. Needless to say, as the joint case 22 swings, the second drive rotor 8 and the rotor motor 21 swing together.

  The swinging direction of the second drive rotor 8 at this time is a direction in which the lower side (projecting end side) is moved up and down in the rotor axial direction. In other words, the second drive rotor 8 can be provided with an inclination such that the protruding end side protrudes radially outward from the rotor outer peripheral surface of the first drive rotor 7. Therefore, when the cylindrical fabric W wound around the first drive rotor 7 and the second drive rotor 8 is rotated around the cylindrical axis, the cylindrical fabric is caused by the inclination component of the second drive rotor 8. A spiral upward rotational force can be applied to W. This ascending rotational force determines the ascending dimension of the cylindrical fabric W, and the tape width of the tape fabric T cut out from the upper peripheral portion of the cylindrical fabric W is influenced.

One end of the horizontal shaft 18 is provided with a cross-type transmission portion 23 formed by meshing a worm gear and a worm wheel, and a handle shaft 24 a of the operation handle 24 is connected to the cross-type transmission portion 23. Therefore, the rotational force can be transmitted to the horizontal shaft 18 by rotating the operation handle 24.
A bearing base 28 having a slotted shaft hole 28 a is provided at the other end of the horizontal shaft 18 that is opposite to the joint case 22. A lock bolt 29 with a clamp lever capable of tightening a slot is screwed to the bearing base 28. When the lock bolt 29 is rotated in the loosening direction, the horizontal shaft 18 can be freely released. If the lock bolt 29 is rotated in the tightening direction, the horizontal shaft 18 can be locked so as not to rotate.

  The tension rotor 9 (see FIG. 1) applies tension to the cylindrical fabric W wound around the first drive rotor 7 and the second drive rotor 8 so as to increase the cylinder diameter. And is held rotatably. In addition, the tension rotor 9 is separated from the first drive rotor 7 and the second drive rotor 8 so as to be more upward (root side) than the lower side (protrusion end side) in the rotor axial direction. B) It is provided at an angle.

  Further, the inclination component includes an inclination angle that unwinds the cylindrical fabric W obliquely upward. With this inclination angle, a spiral upward rotational force is exerted on the rotating cylindrical fabric W. It also has the role of granting. The tension rotor 9 is attached to the head unit 4 or the vertical frame 3 by an attachment arm 37 provided with a mechanism that allows the angle adjustment and the inclination direction to be adjusted obliquely.

Next, the cutting unit 12 will be described.
As shown in FIGS. 2 to 4, the cutting unit 12 includes rotating blades 25 and 26 that come into contact with each other so as to sandwich the outer peripheral surface of the tubular fabric W from both the front and back sides (outside the cylinder and inside the tube). A cutting motor 27 (see FIG. 1) for rotating these rotary blades 25 and 26 is provided. The rotary blades 25 and 26 are rotated in a relative reverse direction by a gear mechanism (not shown) or the like, and the driving of the cutting motor 27 is input to the gear mechanism. As the cut-out motor 27, a control motor such as a stepping motor or a servo motor can be employed. A DC brushless motor, a general (with brush) motor, or the like may be employed.

Therefore, the cutting portion 12 cuts the upper periphery of the cylindrical fabric W (a position where only the tape width of the tape fabric T enters from the end of the tube). That is, this cut is stretched and formed in a spiral shape along the cylinder axis direction of the tubular fabric W as the tubular fabric W rotates, and as a result, the tape fabric T is cut out.
In addition, the rotary blades 25 and 26 can be configured to include only one of them. In some cases, the rotary blades 25 and 26 can be replaced with a laser cutting machine, a notch blade (reciprocating type) cutting machine, or the like.

Next, the position adjustment mechanism 13 will be described.
As shown in FIGS. 4 and 5, the position adjustment mechanism 13 is provided with a plurality of winding drive means 30 in a radial arrangement around the rotor shaft 8 a with respect to the outer peripheral surface of the second drive rotor 8. is there. Each winding drive means 30 has a structure in which an endless belt 32 is wound around the rotor shaft 8a of the second drive rotor 8 via pulleys 31 provided at the tip and base ends thereof. Each winding drive means 30 is arranged so that the belt surface of the endless belt 32 is exposed so as to be along the outer peripheral surface of the rotor of the second drive rotor 8.

  An input wheel 35 is connected to the pulley 31 at the base end portion through a cross-type transmission portion 34 such as a helical gear or a bevel gear. The input wheel 35 is rotatably held around the rotor shaft 8a, and driving from a drive motor 39 (see FIG. 7) is input to the input wheel 35 via a transmission means 36 such as a toothed belt. It has become so. As is apparent from FIG. 7, the drive motor 39 is fixed to the joint case 22 provided at the connecting portion between the second drive rotor 8 and the rotor motor 21, and the angle adjusting mechanism described above. When the second drive rotor 8 swings by the operation of 19, the drive motor 39 also swings integrally with the joint case 22.

Due to such a structure, when the drive motor 39 is driven, the drive from the input wheel 35 is distributed to the respective winding drive means 30, and these respective winding drive means 30 are simultaneously driven in the same direction. Therefore, the endless belt 32 circulates and runs along the rotor shaft 8a of the second rotor 8, and the running force of the endless belt 32 applies a moving force along the cylindrical axis direction to the inner surface of the tubular fabric W. It is what

However, the second drive rotor 8 is rotationally driven by the rotor motor 21 in synchronism with the rotation of the first drive rotor 7 as described above. Therefore, the pulley 31 of each winding drive means 30 is configured to be held by a pulley bracket 38 key-fitted to the rotor shaft 8a so as to rotate integrally with the rotor shaft 8a of the second drive rotor 8. ing.
Accordingly, in connection with this, the input wheel 35 that distributes the driving force to each winding drive means 30 has a rotational speed (that is, the same rotational speed) that does not cause a relative speed difference with the rotor shaft 8a of the second drive rotor 8. It is necessary to set the rotating state as a stop state of each winding drive means 30. In other words, the drive motor 39 for rotationally driving the input wheel 35 rotates each time when the input wheel 35 is rotated at the same rotational speed as the rotor shaft 8a of the second drive rotor 8 and the rotational speed is increased. When the hanging driving means 30 performs one-way driving (for example, driving in the direction in which the cylindrical fabric W is lowered), and on the contrary, when the vehicle is decelerated, each winding driving means 30 is driven in the other direction (for example, the cylindrical fabric W). Driving in the direction to raise the).

  Since each winding drive means 30 is radially arranged around the rotor shaft 8a of the second drive rotor 8 as described above, each endless belt 32 rotates in the circumferential direction when the second drive rotor 8 rotates. Move. Such circumferential movement of the endless belt 32 exhibits a rotational force imparting action around the cylindrical axis with respect to the inner surface of the tubular fabric W and an anti-slip effect of the tubular fabric W against the rotational force.

Next, the position detection unit 14 will be described.
The position detection unit 14 detects the position (appropriate cutting position) where the cutting unit 12 should cut the tubular fabric W with the tubular fabric W wound around the rotors 7 to 9 being detected. is there. As shown in FIGS. 3 and 4, the position detection unit 14 is on the upstream side of the cutting unit 12 in the rotation direction of the cylindrical fabric W (the direction in which the cylindrical fabric W is fed toward the cutting unit 12). It arrange | positions in the position (each right side of the cutting part 12 in FIG. 3, FIG. 4).

  The position detection unit 14 includes three sensors 40 to 42 that are arranged so as to be shifted from each other in the direction along the cylinder axis of the cylindrical fabric W (the vertical direction in FIG. 3). Among the three sensors 40 to 42, the sensor 40 arranged closest to the cutting part 12 is for detecting a spiral cutting line L displayed with a tape width of 1 pitch with respect to the tubular fabric W. It is regarded as a “suitable position sensor”. That is, if the cutting line L matches the cutting position by the cutting unit 12, it can be determined or confirmed that the cutting position is appropriate.

  On the other hand, the sensor 41 arranged adjacent to the appropriate position sensor 40 is a “lower limit sensor” that detects that the cutting line L has deviated downward from the appropriate position sensor 40. Further, the sensor 42 arranged adjacent to the lower limit sensor 41 (arranged farthest from the appropriate position sensor 40) is an “upper limit sensor” that detects that the cutting line L has deviated upward from the appropriate position sensor 40. ing.

For the appropriate position sensor 40, the lower limit sensor 41, and the upper limit sensor 42, when the cutting line L is a highly reflective color such as white, a reflective photosensor can be used. However, when the cutting line L is a color having low reflectivity due to the fabric color or pattern of the cylindrical fabric W, it is preferable to use a color sensor.
A leveling plate 44 is provided between the appropriate position sensor 40 and the cutting part 12, and two hold-down bars 45 are provided upstream of the upper limit sensor 42. The leveling plate 44 and the restraining bar 45 both serve to suppress fluttering of the tubular fabric W, remove wrinkles, and prevent meandering. Accordingly, the leveling plate 44 provides an effect that the cutting of the cylindrical fabric W by the cutting unit 12 is performed reliably and cleanly, and the restraining bar 45 enables the position detection unit 14 to accurately detect the cutting line L. An effect is obtained.

By the way, in order to display the cutting line L for the cylindrical fabric W, as shown in FIG. 6, the cylindrical material fabric W ₀ is knitted by a circular knitting machine, and this cylindrical material fabric W ₀ is laid on its cylindrical axis. to one fabric W ₁ cut open along the direction. In the single dough W ₁ formed in this way, slit lines α and β are formed on both sides of the dough (left and right in FIG. 6).
The reason why the single-piece fabric W ₁ is obtained using the cylindrical material fabric W ₀ is that there are advantages such as ease of production, high productivity, and low cost. The knitting of the material cloth W ₀ is not necessarily indispensable as a procedure (condition) for obtaining the single cloth W ₁ .

A plurality of straight lines arranged so as to pass through the slit lines α, β on both sides parallel to the course direction and to be parallel to each other are displayed on the single fabric W ₁ by inkjet printing or the like. Thereafter, the cut cloths α ₁ and β are connected to each other so as to form a cylindrical cloth W having a cutting line L.
As a method for connecting the slit lines α and β, sewing, adhesion, fusion, or the like may be employed. In addition to printing, the straight line used as the basis of the cutting line L is a method of performing jacquard knitting every corresponding course or knitting with colored yarn when knitting the tubular material fabric W ₀ in a circular knitting machine. It can be displayed by adopting a method of inserting.

Incidentally, in forming the tubular cloth W from a single fabric W ₁ is line cut open stitching alpha, on both sides of the beta, it may be to shift by one pitch the straight line to the original cut lines L in the cylinder axis direction .
If it explains clearly, "a" will be displayed on the cloth side edge along the cut line β on one side between the first and second cutting lines L, L from the top, and hereinafter, "b" will be directed downward. It is assumed that lowercase letters are temporarily displayed such as “c”, “d”... A “☆” mark is displayed between the lowest cutting line L and the upper cutting line L.

On the other hand, a “★” mark is displayed between the first and second cutting lines L, L from the top on the fabric side edge along the cut line α on the other side. Then, “A” is displayed between the next second and third cutting lines L, L, and thereafter, lower case letters such as “B”, “C”, “D”... Are temporarily displayed. Shall.
After this display, “A” on the cut line α side and “a” on the cut line β side are matched, and similarly, “B” and “b”, “C” and “c”, “ D ”and“ d ”... In the cylindrical fabric W manufactured by connecting the slit lines α and β in such a state, the “★” mark on the slit line α side protrudes upward, and the “☆” mark on the slit line β side downwards. The fabric side edge on the slit line β side is shifted downward by 1 pitch from the top with respect to the fabric side edge on the slit line α side.

That is, in this cylindrical fabric W, the cutting line L is shifted by 1 pitch in the cylindrical axis direction on both sides of the slit lines α and β. Therefore, compared with the cylindrical material fabric W ₀ , the course direction of the stitch (round knitting) The circumferential direction as a cylinder when the knitting is advanced by the machine is twisted spirally in the cylinder axis direction. Therefore, when the tape fabric T is cut out using the tubular fabric W, the longitudinal direction of the cut tape fabric T is parallel to the course direction.

Therefore, in this tape fabric T, when it is pulled in the longitudinal direction, linear expansion and contraction along the course direction occurs, and an advantage that no twisting is obtained can be obtained. This advantage is a great feature in that when the tape fabric T is attached to clothing (for example, the waist portion of the pants), the clothing can be prevented from being twisted.
Next, the fabric receiving table 15 will be described.

  As shown in FIG. 1, the fabric receiving base 15 provided below the rotors 7 to 9 can support the cylindrical fabric W that is wound around the rotors 7 to 9 and hangs down in a zigzag folded state. It is formed as an area. The base portion 2 that supports the cloth receiving base 15 is provided with a turning motor 47 for driving the cloth receiving base 15 to turn. The turning motor 47 may be a DC brushless motor, a general (with brush) motor, or the like.

Next, the control unit 16 will be described.
The controller 16 includes a rotor motor 20 for rotationally driving the first drive rotor 7, a rotor motor 21 for rotationally driving the second drive rotor 8, and a position incorporated in the second drive rotor 8. A drive motor 39 for driving the adjusting mechanism 13, a cutting motor 27 for rotating the rotary blades 25 and 26 of the cutting unit 12, a turning motor 47 for rotating the dough receiving base 15, and position detection Three sensors (appropriate position sensor 40, lower limit sensor 41, and upper limit sensor 42) included in the unit 14 are connected via their drive circuits (drivers and the like).

The control unit 16 operates the amount of operation (such as the number of rotations of the cylindrical fabric W) acquired from the rotor motors 20 and 21 and the position information (position of the cutting line L in the cylindrical fabric W) output from the position detection unit 14. ), The position adjusting mechanism 13, the cutting unit 12, and the cloth receiving base 15 are controlled. The contents of these controls will be described in the operation status of the tape cloth manufacturing apparatus 1. .

Next, the operation state of the tape fabric manufacturing apparatus 1 according to the present invention will be described.
A cylindrical fabric W in a zigzag folded state is placed on the fabric receiving table 15, and one cylindrical end on the folded upper surface is lifted from the cylindrical fabric W, and the first drive rotor 7, the second drive rotor 8, The tension rotor 9 is wound around and installed. If necessary, the angle adjustment mechanism 19 is operated to adjust the angle of the second drive rotor 8, or the inclination angle of the tension rotor 9 is adjusted by the mounting arm 37.

  After the tubular fabric W is mounted, the rotor motors 20 and 21 are operated to rotate the tubular fabric W around its cylinder axis so that the first drive rotor 7 and the second drive rotor 8 are rotated in the same direction. Let When the operation of the rotor motors 20 and 21 is started, the control unit 16 operates the cutting motor 27 of the cutting unit 12 to rotate the rotary blades 25 and 26 in the reverse direction. At this time, the control unit 16 performs control so that the peripheral speeds of the rotary blades 25 and 26 are higher than the peripheral speed of the cylindrical fabric W that is rotated by driving of the rotor motors 20 and 21.

  By increasing the peripheral speed of the rotary blades 25 and 26 in this way, even when the cylindrical fabric W is a fabric having a large stretchability (a fabric that is difficult to apply a tension that expands the cylinder diameter), the tension Reliable cutting is possible while maintaining an appropriate tension by the rotor 9, and a beautiful cutting line can be obtained. This effect is derived from the effect that the tape fabric T can be cut out using the cylindrical fabric W having a large diameter, and productivity and low cost can be promoted accordingly.

At the same time, the control unit 16 also operates a turning motor 47 for rotationally driving the dough receiving base 15. The rotation of the cloth receiving base 15 by the turning motor 47 may be continuous rotation or intermittent rotation. However, at this time, the control unit 16 drives the turning motor 47 to rotate the fabric receiving base 15 within the rotation amount before reaching the rotation amount at which the tubular fabric W is twisted.
For example, in the case of continuous rotation, the rotational speed of the cylindrical fabric W that is rotated by driving the rotor motors 20 and 21 and the rotational speed of the fabric receiving base 15 may be the same. In the case of intermittent rotation, the dough receiving base 15 may be rotated once after the cylindrical dough W is rotated once. In any case, the cylindrical fabric W does not twist more than one rotation between the head part 4 and the fabric receiving table 15, and as a result, the tubular fabric W has a downward movement due to the twist. The action of being pulled to the side is not added. Therefore, the variation in the tape width due to the twist of the tubular fabric W does not occur.

  When the rotor motors 20 and 21 start to operate as described above, in the position detection unit 14, the appropriate position sensor 40 detects the cutting line L, and the lower limit sensor 41 and the upper limit sensor 42 are not detected. While the appropriate position sensor 40 is detecting the cutting line L, the cutting line L displayed on the cylindrical fabric W matches the rotary blades 25 and 26 of the cutting unit 12 (the appropriate position is cut). Will be). Therefore, even if the control unit 16 receives such a signal from the position detection unit 14, the control unit 16 maintains the mounting position of the tubular fabric W without operating the position adjustment mechanism 13.

At this time, the control unit 16 does not control the position adjustment mechanism 13 but performs control of “non-operation”.
However, when the appropriate position sensor 40 is not detected in the position detection unit 14 and the lower limit sensor 41 or the upper limit sensor 42 is in the detection state (after either the lower limit sensor 41 or the upper limit sensor 42 detects the passage signal of the cutting line L). (Including the case where it is in a non-detection state), the cutting line L is displaced from the detection point of the appropriate position sensor 40 toward the lower limit sensor 41 side or the upper limit sensor 42 side. Therefore, the control unit 16 increases or decreases the speed of the drive motor 39 of the position adjustment mechanism 13 until the appropriate position sensor 40 detects the cutting line L when receiving the signal from the position detection unit 14. Thus, the winding drive means 30 controls the cylindrical fabric W to move downward or upward.

  The control of the position adjustment mechanism 13 by the control unit 16 as described above is always performed based on the output of the position detection unit 14 while the rotor motors 20 and 21 are operating. For this reason, the tape fabric having a constant tape width is reliably maintained in which the cutting line L displayed on the cylindrical fabric W matches the rotating blades 25 and 26 of the cutting portion 12 (the appropriate position is cut). T will be cut out.

As is apparent from the above description, in the tape fabric manufacturing apparatus 1 according to the present invention, the tape fabric T can be cut out while maintaining the tape width with high accuracy, and the tape width can be easily changed. It can be performed quickly, and can eliminate and eliminate conventional problems.
In the tape fabric manufacturing apparatus 1 according to the present invention, it has been confirmed that the tape width of the tape fabric T can be stored with high accuracy within plus or minus 1 mm, thereby dramatically improving the quality of clothing using the tape fabric T. Can be improved.

The present invention is not limited to the embodiment described above, and can be changed as appropriate according to the embodiment.
For example, in the tape dough producing apparatus 1 according to the present invention, it has already been described that it is not limited to obtain the single dough W ₁ using the tubular material dough W ₀ . In addition, when the cylindrical material fabric W ₀ is not used, a woven fabric can be employed when obtaining the single fabric W ₁ .

In addition, it is not limited that the cylindrical fabric W is created based on the single fabric W _{1. The} tubular fabric W is a knitted fabric (cylindrical fabric) that is knitted by a circular knitting machine or the like. You can also
Displaying the cutting line L on the tubular fabric W is not limited, and the position detection unit 14 can also be provided to detect the upper peripheral edge of the tubular fabric W. In the above embodiment, the alphabetic characters and capital letters are displayed between the cutting lines L and L for convenience of explanation, and can be simplified, omitted, or provided with another symbol. Needless to say, it can be replaced with.

When a straight line based on the cutting line L is displayed on the single fabric W ₁ , this straight line is parallel to the course direction of the stitch, and the cylindrical fabric W is formed on both sides of the slit lines α and β. It is also possible to display the image diagonally from the beginning so as to shift by one pitch in the cylinder axis direction.
As long as the first drive rotor 7 and the second drive rotor 8 are provided, the number of other rotors (such as the tension rotor 9) is not limited. The tension rotor 9 can also be omitted.

  The position adjustment mechanism 13 is not limited to be provided for the second drive rotor 8, and can be provided separately and in contact with the outer peripheral surface of the cylindrical fabric W, for example. Further, the position adjusting mechanism 13 is not limited to the one provided with the wrapping driving means 30. The wrapping driving means 30 is replaced with a disk driving means (a structure in which the disk is substituted for the endless belt). Substitution is also possible.

The angle adjusting mechanism 19 for adjusting the angle of the second drive rotor 8 has been described as being manually operated by the operation handle 24. However, an automatic control system including a pulse motor or a servo motor may be employed. It is.
Note that, if the angle of the second drive rotor 8 is changed, the tension angle of the cylindrical fabric W wound around the first drive rotor 7 also changes. It is also predicted that a deviation occurs in the approach angle of the cylindrical fabric W toward the meshing position with the blades 25 and 26. Therefore, in order to deal with such a case, the mounting base portion 50 (see FIG. 1) of the second drive rotor 8 is moved in a direction along the base surface (a direction orthogonal to the rotor axis of the first drive rotor 8). It is preferable to adopt a structure that enables it.

  With respect to the “rotation amount at which the cylindrical fabric W is twisted” as a guideline when the control unit 16 operates the turning motor 47 of the fabric receiving base 15, “one rotation of the cylindrical fabric W” is used in the above embodiment. Although described as a standard, it can be appropriately increased or decreased according to the quality of the fabric. In short, it suffices if it is possible to prevent the tubular fabric W from being twisted by being pulled downward.
