Description

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 rotating a cylindrical cloth.

[0002]

2. Description of the Related Art At the time of manufacturing clothing, for example, a narrow cloth having a predetermined length may be used for a neck portion, a cuff (cuff) portion, or a crotch portion of a lower product. However, such a part cloth is generally obtained by cutting a predetermined length from a long tape cloth. In order to manufacture the tape material, the tape material is cut out from the cylindrical material W using a rotary processing device 100 as shown in FIG.

[0003] The rotary processing apparatus 100 includes a pair of rotors 101 and 102 arranged side by side at a predetermined interval from each other.
A rotation driving means (not shown) for rotating at least one of the rotors 101, and a pair of pinch rollers 103 capable of pinching a part of the cylindrical cloth W wound around the rotors 101 and 102 in the circumferential direction. And processing means 105 such as a cutter capable of abutting against the upper peripheral portion of the tubular cloth W. Each roller 106 of the pinch roller pair 103 is rotatable, and as a whole, the angle can be changed along the surface direction of the tubular material W.

[0004] That is, if the tubular material W is wound around the rotors 101 and 102, tension is generated in the circumferential direction of the tubular material W and the tubular material W does not fall. To operate both rotors 101, 1
The cylindrical fabric W is driven to rotate around 02. In addition, by inclining the pinch roller pair 103, directivity is provided to the cylindrical fabric W so as to be directed upward during circulation. While doing so, the tape cloth T having a predetermined width is cut out spirally from the upper peripheral portion of the cylindrical cloth W by the processing means 105.

[0005]

A conventional rotary processing apparatus 1
00 was effective when processing a relatively small-diameter cylindrical fabric W. By the way, for example, the operation of cutting out the tape cloth from the cylindrical cloth W is made more efficient (the rotary processing apparatus 10).
In order to reduce the number of times the cylindrical cloth W is set to 0), or when a wide part cloth is required, the diameter of the cylindrical cloth W may need to be increased. As the diameter increases, the cylindrical fabric W naturally increases in weight. Also, when a thick material is requested as the part material, the weight of the cylindrical material W will increase.

In the case of the cylindrical cloth W having increased weight as described above, the rotor
By making adjustments such as widening the interval between 1,102,
Even if the application is attempted, if the pinch roller pair 103 is angle-changed, it is not possible to give the tubular fabric W directivity such that it goes upward during the rotation of the tubular fabric W ( The force is insufficient with the pinch roller pair 103), so that it is not applicable.

[0007] Under such circumstances, development of a rotary processing apparatus that can be adapted to the cylindrical cloth W whose weight has increased due to an increase in diameter or the like has been desired. The present invention has been made in view of the above circumstances, and when processing while rotating the cylindrical fabric, even if the cylindrical fabric is increased in weight, it is possible to perform reliable processing. It is an object of the present invention to provide a method for rotating a cylindrical dough and a rotary processing apparatus used for the method.

[0008]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the method and the apparatus for rotating cylindrical fabric according to the present invention, among the rotors on which the tubular fabric is wound and mounted, at least one of the rotors can be changed in angle, and the degree of inclination of the rotor is determined. , And the cylindrical dough is fed along the axial direction.

[0009] For example, assuming that a tubular material is wound around a vertical rotor and the upper end portion of the tubular material falls below a predetermined level and is lowered while rotating around the rotor. Then, the upper end side of the rotor is tilted outward in the radial direction. Then, the diameter of the cylindrical fabric is increased toward its upper peripheral portion, and the upward-directed feed is added. Conversely,
When the upper end portion of the tubular cloth exceeds a predetermined level and becomes higher, the rotor is set upright or tilted radially inward. Then, the diameter of the cylindrical fabric is reduced at the upper peripheral portion thereof, and downward-directed feeding is added.

By repeating such a process, the upper end level of the tubular material can be always kept constant. As is evident from this, in the present invention, the rotor itself for applying tension to the cylindrical fabric in the circumferential direction to maintain the wound mounting state, that is, in the case of making the rotor a vertical type, The rotor itself, which prevents falling,
The angle is changed directly. Therefore, it is possible to cope with an increase in the weight of the tubular material.

In this way, processing is performed by the processing means while feeding the cylindrical cloth in the axial direction. It is needless to say that a cutter can be used as the processing means. For example, as a cylindrical cloth, a tape cloth area having a predetermined width and a connecting area formed with a predetermined width by a molten yarn are used. And are knitted so as to form a spiral around the cylinder axis along the cylinder axis direction, with this being one lead, after being in parallel with each other.
If it is manufactured in advance, it is possible to configure the processing means by heating the connection area.

A tubular fabric in which the above-described connection region made of molten yarn is knitted can be knitted by using a circular knitting machine or the like.

Further, the cylindrical cloth W is detected by the upper sensor 24a.
When it is detected that the upper end of the cylindrical cloth W has exceeded the predetermined level, the inclination angle control means 6 controls the rotating shaft 3a of the rotor 3 so as to incline radially inward toward the upper side to lower the cylindrical cloth W. Let it do. Further, by performing these controls, when the middle sensor 24b detects that the upper end of the tubular fabric W has reached a predetermined level, the state is maintained and the tubular fabric W is maintained at a constant level. I do.

The rotating shafts 2a, 3 of the rotors 2, 3
The interval a is set such that in the state where the tubular fabric W is hung around the rotors 2 and 3, an appropriate circumferential tension is generated in the tubular fabric W and the tubular fabric W does not fall. In addition, on the outer peripheral surfaces of the rotors 2 and 3, numerous countless fine projections are provided, or a roughened slip band 25 (see FIGS. 4 and 5) is wound around the rotor 2, 3. The slipping of W in the circumferential direction and downward can be more reliably prevented.

As shown in FIGS. 3 and 6, the processing means 7
Is a hot air generator 27 capable of blowing hot air to the outer peripheral portion of the upper portion of the cylindrical fabric W, and a hot air generator 27 that backs up the cylindrical fabric W on the inner surface side of the cylindrical fabric W It has a guide plate 29 for restricting the hot air to a predetermined range by the notch 28, and an exhaust pipe 30 for guiding the hot air that has passed through the notch 28 of the guide plate 29 to exhaust.

As shown in FIG. 7, the cylindrical cloth W used in the present embodiment has a predetermined width to be taken out as a tape cloth T.
It is integrally wound around the cylinder axis P in a wound state so as to draw a spiral along the direction of the cylinder axis P. As shown in an enlarged manner in FIG. 8, a portion (E portion) of the tubular fabric W has a predetermined width portion taken out as the tape fabric T as described above at the time when the tubular fabric W is formed. The tape cloth region 50 is connected to each other along the longitudinal direction of the tape cloth region 50 via a connection region 51.

That is, the mutually parallel state of the tape material region 50 and the connection region 51 corresponds to one lead, which is knitted so as to draw a spiral around the cylinder axis P. The connection region 51 is made of a molten yarn. Then, the tape fabric regions 50 are knitted so as to straddle the tape fabric regions 50 on both sides after the tape fabric regions 50 are directly abutted with each other, or the tape fabric regions 50 do not contact each other. In addition, the knitting is performed so as to have an independent knitting width as a connecting area 51 between the tape cloth areas 50 on both sides.

Further, as the molten yarn used as the material, a yarn having a relatively low melting point, such as a low-melting polyester yarn or a low-melting nylon yarn, is used. In addition, a polyethylene or polypropylene yarn material may be used. It is preferable that the melting point of such a molten yarn is set to be lower than about 200 ° C. For example, if a low melting point nylon yarn HT-1 manufactured by EMS is used, the melting point is 16
The melting point can be set to about 130 to 140 ° C. by using HT-2.

The molten yarn may be a twisted yarn, a plying yarn, a plying yarn, or a drawn yarn. On the other hand, the tape fabric area 50 is knitted from vegetable fibers such as cotton yarn, animal fibers such as wool, and other various synthetic fiber yarns. It is used and has a required width dimension.

However, when using synthetic fiber yarns, it is necessary to pay special attention. As the yarn material used for the tape material region 50, a material having a higher melting point than the molten yarn forming the connection region 51 is used. Election is required. In the present embodiment, the tape cloth regions 50 are arranged in a mutually parallel state along the spiral direction, and in the width direction, the thick white line portion 50a, the thin black line portion 50b, the thin white line portion 50c, and the thick black line portion 50c. Material yarns of a plurality of colors are used so that the line portions 50d are alternately arranged in color, and the whole thereof has a border pattern. Therefore, when taken out as the tape material T (part material S), the use range thereof can be expanded.

Next, using the rotary processing apparatus 1 according to the present invention described above, the tape cloth T
Based on the procedure for manufacturing the rotary processing method, the rotary processing method according to the present invention will be described. First, as shown by a two-dot chain line in FIG. 2, the upper peripheral portion of the tubular fabric W is wound around the rotors 2 and 3 from below, so as not to fall, and The extra length of the tubular material W is placed on the swivel table 13.

Then, the rotation driving means 5 is operated to start the circular driving of the tubular cloth W via the rotor 2. Further, the processing means 7 is operated to start heating the outer peripheral surface of the upper peripheral portion (see the white arrow X in FIG. 1) of the tubular cloth W. By doing so, the tubular fabric W is melted by heating the connection region 51 (see FIGS. 7 and 8),
The tape cloth regions 50 are separated from each other. That is, one end side (upper end side) of the cylindrical fabric W in the cylinder axis direction.
Then, since one tape cloth region 50 is sequentially separated by itself, the tape cloth T may be taken out as a tape cloth T.

In the processing means 7, the hot air from the hot air generating device 27 is supplied to the notch 2 of the guide plate 29 (see FIG. 6).
8, the air is immediately exhausted through the exhaust pipe 30, so that the hot air does not act on the area other than the necessary area of the tubular fabric W, and therefore, the melting of the connection area 51 at an unnecessary part or the like. A countermeasure is taken so as not to cause overheating and the like of the tape fabric region 50.

The tape material T thus taken out is:
After that, it may be cut into a predetermined length to form the part fabric S. If the tape material region 50 is separated from the upper peripheral portion of the cylindrical material W as described above, the upper end level of the cylindrical material W drops. Based on the signal, the inclination angle control means 6 changes the necessary angle with respect to the rotor 3,
The cylindrical cloth W is always kept at a constant level while basically being raised (sometimes while being lowered and kept in parallel).

Further, when the tubular material W goes around the rotors 2 and 3 several times, the tubular material W will be twisted in the middle of the suspended portion. When the thinning is detected by the sensor 14 (see FIG. 2), the turning table 13 rotates in the same direction as the circling direction of the tubular cloth W at a speed higher than the circling speed. The turning table 13 automatically stops after a predetermined number of revolutions, a predetermined time, or an operation signal from the sensor 14.

When the above operation is continued until the tubular cloth W on the swivel table 13 disappears and also around the rotors 2 and 3, one cycle operation is completed. By the way, the present invention is not limited to the above embodiments. For example, the detailed structures of the rotation driving means 5 and the like, including the inclination angle control means 6, can be appropriately changed to various conventionally known structures. Therefore, it is possible to change the angle of both rotors 2 and 3 by the inclination angle control means 6 and to rotate the two rotors 2 and 3 by the rotation driving means 5.

It is also possible to use a plurality of rotors 2 and 3, respectively (that is, a configuration having three or more rotors as a whole). As the processing means 7, in addition to the hot air generator 27, a microwave irradiation device, a steam injection device, or the like, such as a heating wire proximity device, can be used. As in the conventional case, it is possible to use a cutter (including not only a knife but also various other non-contact scalpel devices, etc.), and it is also possible to employ a device for coloring, sewing, or the like.

Further, the processing means 7 may move the cylindrical fabric W up and down along the cylinder axis direction. The material, size, coloring, and the like of the tubular fabric W are not limited at all.

[0034]

As is apparent from the above description, in the method and apparatus for rotating a cylindrical material according to the present invention, at least one of the rotors on which the cylindrical material is wound is mounted at an angle. According to the degree of inclination of the rotor, the cylindrical cloth is fed in the axial direction, that is, the angle-changeable rotor applies a circumferential tension to the cylindrical cloth and winds the cloth. Since it is intended to maintain the re-attached state, it is possible to cope with an increase in the weight of the tubular material.

Therefore, when processing while rotating the cylindrical material, reliable processing can be performed even for a heavy cylindrical material. In addition, as a tubular dough,
If a region for tape cloth having a predetermined width and a connection region formed with a predetermined width by a molten yarn are knitted so as to draw a spiral in an alternate arrangement, and the processing means is a heating means,
There is also obtained an advantage that the processing operation can be facilitated and the efficiency can be improved.
