Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrinkle remover for tubular knit fabrics, and more particularly to a wrinkle remover for tubular knit fabrics capable of removing wrinkles from a circular knit fabric that has been dyed.

[0002]

2. Description of the Related Art Knitted fabric is a highly stretchable fabric produced by circular knitting. For example, trainers have back hair and W face cloth, polo shirts with Kanoko cloth, tank tops with Teleko cloth, T-shirts with Tenjiku cloth, golf wear with Kanoko, Smooth,
W-face and punch fabrics are used, and cardboard knit and mesh fabrics are used for other sports clothing.

The knit fabric is manufactured into a cylindrical shape by circular knitting, subjected to a necessary refining process, a dyeing process, a drying process, a wrinkle removing process, and then delivered to a garment manufacturing processor. Fabric dyeing processing has been conventionally performed by a Wins dyeing machine. In the dyeing machine, endless loops are formed by sewing both ends of a circular opening of a tubular long circular knitting fabric, and the loops are conveyed by two rollers and passed through a dyeing solution bath. Is a machine for dyeing fabrics.

The Wins dyeing machine has the advantage of being relatively inexpensive, but since the fabric is easily tensioned,
There is a drawback that wrinkles easily occur in the vertical direction (the direction of the generatrix of the tubular cloth). In order to reduce this tension,
A jet dyeing machine has been developed which runs a dyeing solution in conjunction with the cloth feeding operation. When dyeing with the jet dyeing machine, the incidence of wrinkles is reduced as compared with the Wins dyeing machine.

As another method for suppressing the generation of wrinkles during the dyeing process, it has been considered to prevent the formation of wrinkles by injecting air into the circular knit fabric by a compressor to inflate the circular knit fabric. In addition, in order to prevent wrinkles due to temperature changes during the dyeing process, it is also practiced to constantly raise and lower the temperature over a period of time so that the fabric adapts to the temperature changes.

Other chemical methods include softening the fabric with a chemical called a softener in the bath during dyeing so that the fabric is less likely to wrinkle, and generally during scouring and bleaching before dyeing the fabric. Since the dough used in sodium metakelate hardens the dough, it is also considered to prevent the dough from hardening by using a non-silicic acid scouring bleaching agent.

[0007] Next, in the wrinkle removing process after the dyeing process, a wet type wood boring machine has been conventionally used. The wood trimming machine is a device for extending the dough in the width direction by guiding it in the width direction while guiding it in the width direction while guiding the width of the processed long tubular cloth. The widening of the material spreads the fabric and removes wrinkles. As shown in FIGS. 8 to 10, the spreading frame 200 is inserted inside the tubular knit fabric K in a dehydrated state after dyeing, and the fabric is spread only in the width direction of the fabric. The spreading frame 200 includes a pair of guide bars 201, 201 extending parallel to each other, and a width adjusting member 2 for adjusting a distance between the guide bars 201.
02 and a driven roller 20 that is rotatably attached to each of the guide rods 201 and is in rotary contact with the inner surface of the tubular material.
3a and 203b. The driven rollers 203a, 2
A drive roller 210 is provided at a position opposed to 03b so as to contact the outer surface of the tubular cloth K and cooperate with the driven rollers 203a and 203b to feed the cylindrical cloth in the direction of arrow A. The driven rollers 203a and 203b are barrel-shaped rollers having a maximum diameter in the central portion in the axial direction, and the driving rollers are hourglass-shaped rollers having a minimum diameter in the central portion in the axial direction. It provides a certain frictional force for delivery.

On the downstream side of the spreading frame 200, a pair of nip rollers 230a, 230b for pressing the tubular cloth K in pressure is provided for the final wrinkle removal.

In such a conventional firewood drilling machine, first, the guide rod 20 is adjusted by the width adjusting member 202 according to the diameter of the tubular cloth K.
The distance between 1 and 201 is adjusted, and then the guide rods 201 and 201 are inserted into the inner peripheral surface of the tubular cloth K to expand the tubular cloth K in the width direction. Then, in the process of rotating the pair of drive rollers 210 and running the cloth in the direction of arrow A in cooperation with the inner driven rollers 203a and 203b, the cloth is widened in the width direction. And the fabric is nip roller 2
The effect of ironing is obtained when passing through 30a and 230b. Then, after the fabric is set on the finishing setting machine and the final finishing is performed, the product is shipped to the sewing factory.

[0010]

Conventionally, wrinkles in circular knit clothing products have been fairly tolerated, but in recent years, improvement in quality control has been demanded, and wrinkles in circular knit clothing products have come to be severely checked. It was As a result, even with the wrinkles that were acceptable in the past, we started to receive returns from major mass retailers. For example, if the wrinkles are not removed even after ironing, the fabric will be returned, or if the return does not work, a monetary claim will be made, and domestic fabric dyeing processors will suffer great damage. became.
Therefore, in recent years, there has been an increasing demand to deliver circular knit fabrics that are as wrinkle-free as possible to clothing manufacturing processors.

In order to meet this requirement, wrinkles are inevitably generated on the circular knit fabric during the dyeing process, and therefore it is necessary to suppress the wrinkles during the dyeing process as much as possible, and the wrinkles after the dyeing process are required. It is necessary to have a device for surely removing wrinkles from the circular knit fabric in the removing process.

As the best possible wrinkle removing method at present, dyeing is performed by using a jet dyeing machine to suppress the occurrence of wrinkles during the dyeing process, and then the above-mentioned wet log cutting machine is used. It is possible to do it. However, the jet dyeing machine is extremely expensive as compared with the Wins dyeing machine. Also, when removing wrinkles with a wood plucking machine, the fabric is rubber driven roller 210
And the driven rollers 203a and 203b are pressed and conveyed, the fabric is crushed and a thin mark (scratch) is generated on the surface of the fabric, and the commercial value as the circular knit original fabric is reduced. If the pressure contact between the rollers is too strong,
There is a possibility that the surface of the fabric will have a shine (shininess) as if it had been ironed several times. In other words, there is a dilemma that the more the fabric is expanded to remove wrinkles, the more easily the surface of the fabric becomes scratched and shiny, and the attempt to suppress the occurrence of scratches results in insufficient wrinkle removal. Further, wrinkle removal by the widening frame 200 and the driving roller 210 is not sufficient, so the nip rollers 203, 203b
However, due to this, a polygonal line is inevitably formed on the tubular cloth K.

Therefore, the present invention can efficiently remove the wrinkles generated in the fabric during or before the dyeing process to the maximum extent, and the surface side of the fabric is not scratched, which eliminates the need for an expensive dyeing machine. Another object of the present invention is to provide a tubular knit fabric wrinkle remover capable of expanding the fabric width by expanding the width of a knit fabric, which is difficult to form, and obtaining a good finish.

[0014]

In order to solve the above problems, the present invention provides a base portion, a first support member supported by the base portion and extending in one direction, and capable of approaching and separating from the first support member. A second support member extending substantially parallel to the first support member, and at least two sets of endless belt transport mechanisms attached to the first support member for supporting and transporting the inner peripheral surface of the tubular knit fabric. And at least two sets of endless belt conveying mechanisms attached to the second supporting member for supporting and conveying the inner peripheral surface of the tubular knit fabric, and the second supporting member with respect to the first supporting member. In order to adjust the distance in a second direction orthogonal to the one direction so as to be able to approach and separate from each other, the adjusting means is provided between the first and second supporting members, and the endless belt is obtained by a combination of outer surfaces The contour line has a substantially cylindrical shape or an oval shape, and is adjusted by adjusting the adjusting means. A wrinkle remover for a tubular knit fabric that adjusts the contour line to bring all the outer side surfaces of the endless belt into contact with the inner peripheral surface of the tubular knit fabric to support and convey the tubular knit fabric in an expanded state. is doing.

[0015]

The adjusting means adjusts the distance between the first and second supporting members in the second direction according to the size of the tubular knit fabric. As a result, the circular size of the contour line obtained by combining the outer surfaces of the respective endless belts is changed, and the width of the tubular knit fabric is determined. Next, by covering the one end opening of the damp tubular knit fabric from one end side of the endless belt and driving all the endless belts to drive, the inner peripheral surface side of the tubular knit fabric rides on the endless belt and is conveyed. To be done. In the process of such conveyance, the diameter of the tubular knit fabric is expanded and wrinkles are removed.

[0016]

In, three sets of endless belt conveyance mechanisms 10 are suspended and fixed. Of the three sets, the central endless belt transport mechanism 1
0A extends vertically downward from the first support member 3,
The remaining two sets of the endless belt conveyance mechanisms 10B and 10C are radially extended from the first support member 3 at symmetrical positions with respect to the central endless belt conveyance mechanism 10A.

Similarly, three sets of endless belt transport mechanisms 11 are vertically fixed to the second support member 7. Of the three sets, the central endless belt conveyance mechanism 11A extends vertically upward from the second support member 7, and the remaining two sets of endless belt conveyance mechanisms 11B and 11C relate to the central endless belt conveyance mechanism 11A. It extends radially from the second support member 7 at symmetrical positions. For simplification, only the upper and lower endless belt transport mechanisms 10A and 11A are shown in FIG. Since the transport mechanisms 10A to 11C have the same configuration, the endless transport belt mechanism 11A will be described with reference to FIGS. 2 to 4.

The transport mechanism 11A includes a leg portion 11a fixed to the second support base 7 and a side plate 11 connected to the leg portion 11a.
b and a pedestal 11c extending between the side plates 10b, and these members form a table. A driven roller 11d is rotatably attached to one end of the side plate 11b, and a drive roller 11e is rotatably attached to the other end.
And between the drive roller 11e and the driven roller 11d,
An endless belt 11f for contacting the back side surface (inner peripheral surface) of the tubular knit fabric K and conveying the fabric is attached.
The endless belt 11f is located above the pedestal 11c.

A mounting plate 11g is fixed to the side plate 11b, and a drive motor 11h is fixed to the mounting plate 11g.
Is fixed. A driven pulley 11j is fixed to the drive roller 11e, and a driving belt 11k is mounted between the pulleys 11i and 11j to transmit the rotational force of the drive motor 11h to the drive roller 11e. The cover 11m for protecting the power transmission system is attached to the mounting plate 11.
It is fixed on g.

As is apparent from the one-dot chain line S in FIG. 2, the contour line obtained by the combination of the outer side surfaces of the respective endless belts is substantially cylindrical or oval. By adjusting the adjusting members 8 and 9, the size of the contour line S is adjusted and all the outer side surfaces of the endless belt are brought into contact with the inner peripheral surface of the tubular knit material to expand the tubular knit material K. It is supported and conveyed in the diameter state.

Next, the operation of the wrinkle remover 1 for tubular knit fabric according to the first embodiment will be described. Depending on the diameter of the tubular knit fabric K in the water-containing state that is to be wrinkled first,
The first and second adjustment members 8 and 9 are operated to adjust the position of the second support member 7 with respect to the first support member 3. At this time, in order to gradually expand the diameter of the tubular knit fabric K, the vertical distance between the free end sides of the first and second supporting members defined by the first adjusting member 8 is set by the second adjusting member 9. It may be set smaller than the vertical distance between the other end of the second support member 7 and the first support member 3 which is defined. As a result, the endless belt 10
The conveyance surface defined by the outer surfaces of f and 11f has a tapered shape, and along with the conveyance of the tubular knit fabric K in the arrow X direction,
The cloth K is gradually expanded in diameter.

Next, the tip portion K1 of the tubular knit fabric K is

Comes into contact with the outer surfaces of the six endless belts and has a circular or oval cross section. Next, the drive motors 10h and 11h are operated to move the respective endless belts 10f and 11f to the table 1
When running on 0c and 11c, the tubular knit fabric K is conveyed in the direction of the arrow X while being expanded in diameter, and wrinkles are removed in the process. Here, tension acts uniformly over the entire circumference of the tubular knit fabric K, and no local tension acts. In addition, since there are six places where the fabric K is spread out, the fabric can be widened by maximizing it, and wrinkles on the fabric can be removed well. Further, since only the back surface of the cloth (the inner peripheral surface of the tubular knit cloth) comes into contact with the transport mechanism, no frictional force acts on the cloth surface, and the threads are not scratched.

When the rear end K2 of the tubular knit fabric K has finished passing through the endless belts 10f and 11f, the fabric K is in a state of covering the peripheries of the first and second support members 3 and 7. At this time, since the cloth is long in length, the cloth is suspended around the supporting members 3 and 7 in a bent state.
Wrinkles in the previous process have been removed. Then, if necessary,
The adjusting members 9 and 8 are adjusted again, the rear end K2 of the tubular knit fabric K is covered on the other ends of the six transport mechanisms 10 and 11, and the drive motor is rotated in the reverse direction to perform a similar wrinkle removing operation in the arrow Y direction. I do. At this time, the mounting position of the tubular knit fabric K with respect to the transport mechanism is made different from the mounting position of the first time, so that another place of the tubular knit fabric K comes into contact with the endless belt, and the wrinkle removing effect is obtained. Can be increased. The front end K1 of the tubular knit fabric K has the conveyor belt mechanisms 10 and 11.
When you go over the tip of, the wrinkle removing work is completed.

Next, a wrinkle removing machine 101 for tubular knit fabric according to a second embodiment of the present invention will be described with reference to FIGS. In these figures, the same members as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. The second embodiment differs from the first embodiment in the number of endless belt conveying mechanisms and the mechanism thereof.

Of the five sets, the central endless belt conveyance mechanism 110A extends vertically downward from the chevron plate 120, and the remaining endless belt conveyance mechanisms 110B to 110E are provided radially and symmetrically.

Similarly, the chevron plate 13 of the second support member 107 is formed.
At 0, five sets of endless belt conveyance mechanisms 111 are vertically fixed. Of the five sets, the central endless belt transport mechanism 1
11A extends vertically upward from the chevron plate 130, and the remaining endless belt conveying mechanisms 111B to 111E.
Are arranged radially and symmetrically. In FIG. 5, the upper and lower endless belt transport mechanisms 110A and 111A are shown for simplification.

Since 1E has the same configuration, the endless conveyor belt mechanism 11
1A will be described.

Unlike the first embodiment, the endless belt 111
f is a plurality of barrel rollers 111n-1
It is supported by 11s. The barrel rollers 111n to 111
s has a drum shape with an enlarged central portion, and a plurality of grooves are engraved in the direction of the generatrix of the outer peripheral surface. Driven roller 1 at the tip
11d and the drive roller 111e at the other end also have the same shape, and these rollers are the leg portions 11 erected from the chevron plate 130.
It is rotatably supported by 1a.

The endless belt 111f is a toothed belt, and the inner peripheral teeth 111f 'engage with the groove of the roller. Further, on the outer peripheral side of the endless belt 111f which comes into contact with the inner peripheral surface of the tubular knit fabric K, ribs 111f ″ are formed at equal intervals in the width direction of the belt in order to enhance the friction transmission force with the fabric K. A drive motor 111h is installed on the second support member 107, and the drive roller 11h is provided via a drive pulley 111i, a drive belt 111k, and a driven pulley 111j.
1e is rotationally driven.

Although such a driving structure is also provided for the lower endless belt conveying mechanism 110A, unlike the first embodiment, the other endless belt conveying mechanisms have a connection relationship with the drive motor. Absent. That is, as shown in FIG. 6, only the upper and lower endless conveyor belt mechanisms 111A and 110A positioned in the vertical direction are driven by the drive motor 111.
h and 110h, and the drive roller equivalent parts of the other endless conveyor belt mechanism are connected to each other by a joint union 140. Therefore, the drive rollers 110A, 11
As 1A rotates, its rotational force is also transmitted to the other endless belt conveyance mechanism.

Two first adjusting members 108 are provided on the tip side of the first and second supporting members 103 and 107. That is, each of the first adjusting members 108 is rotatably provided so as to be immovable in the axial direction with respect to the first supporting member 103, and by rotating the polygonal portion 108b of the screwed shaft portion 108a with a spanner or the like. The screw is screwed back and forth with respect to the second support member, and the position of the second support member 107 with respect to the first support member 103 is adjusted.

Similar to the first embodiment, the contour line S obtained by the combination of the outer side surfaces of the respective endless belts 110f and 111f has a substantially cylindrical shape or an oval shape. Therefore, by adjusting the adjusting members 108 and 109, the size of the contour line S is adjusted, and all the outer side surfaces of the endless belt are brought into contact with the inner peripheral surface of the tubular knit material to expand the tubular knit material. It is supported and conveyed in the diameter state. At this time, since each roller has a barrel shape, the outer contour line becomes more circular. The operation of the second embodiment is also the same as that of the first embodiment, so the description will be omitted.

The present invention is not limited to the above embodiment, and various improvements and modifications can be made. For example, in the first embodiment, the number of endless belt transport mechanisms is three for each support member.
In the second embodiment, the number of sets is five, but the number of sets is not limited, and by providing at least two sets for each support member, the outer contour line by the combination on the outer surface side of the endless belt is substantially circular. Can be However, it is preferable that the endless belt is positioned vertically in relation to gravity. Further, although the cylindrical roller is used in the first embodiment, the barrel roller used in the second embodiment is the first roller.
Incorporating into the embodiment, the surfaces of the pedestals 10c and 11c may have an arcuate cross section. On the contrary, the roller of the second embodiment may be a cylindrical roller. Further, the first adjusting member is not limited to a screw or the like, and a plurality of plate-like spacers for adjusting the distance between the first and second supporting members may be interposed between the both supporting members in the same number. It is possible to obtain the effect of.

[0036]

As described above, according to the wrinkle remover for the tubular knit fabric of the present invention, the following effects can be obtained. (1) Since it is possible to expand the diameter of the tubular cloth to the maximum extent in a circular shape or an oval shape, tension acts evenly on the entire surface of the cloth,
A high wrinkle removing effect can be obtained. (2) It is possible to easily extend the width of a knitted fabric having a narrow tube width, and it is possible to expand the width to increase the use of the cloth width. (3) Since the wrinkle removing effect is high, the wrinkle removing work time can be significantly shortened. (4) Since there is no contact between the outer side surface (front surface side) of the cloth and the processed parts during the wrinkle removing process, the outer surface of the cloth is not scratched and the appearance of the product is not impaired. (5) Since the wrinkle removing effect is high, wrinkles can be removed in the subsequent wrinkle removing step even if dyeing is performed with an inexpensive Wins dyeing machine. In other words, there is no need to use an expensive jet dyeing machine for suppressing the generation of wrinkles during the dyeing process, and the cost of the entire equipment can be kept low. (6) Since the effect of removing wrinkles is high, the nip roller used in the conventional wood trimming machine is also unnecessary, and unnecessary bending lines are not attached to the cloth.
