Description

Material clamping system for edge sewing device of covering cloth with zipper

Technical Field

The zipper-equipped fly is a member that is attached to the opening/closing portion of the clothing so that the clothing, skin, and the like on the inner side of the opening/closing portion are not visible from the outside. The zipper-equipped fabric covering to which the present invention is applied uses, as components, a zipper for opening and closing an opening and closing portion and a cloth called a fabric covering. The present invention also relates to a fastener system for pressing a zipper-equipped fly in a hemming device for a zipper-equipped fly, which hems the fly while conveying the fly of the zipper. The term "hemming" means that the edge of the cover is stitched so that the edge of the cover does not fray.

Background

As an example of a conventional hemming device for a slide fastener attached fabric, there is known a hemming device including: a workbench for carrying a covering cloth with a zipper; a material clamping device which presses the covering cloth with the zipper on the workbench; a sewing machine for hemming the fabric; and a conveying device for the material clamping device, which conveys the material clamping device (patent document 1).

The material clamping device is used for pressing the central part of the covering cloth with the zipper in the width direction, so that the zipper belt and the covering cloth under the zipper belt are pressed together.

Disclosure of Invention

In order to neatly hem a zipper-equipped fabric blank, it is desirable to press the vicinity (inside) of a hem portion (edge portion) in advance. In the case where only the widthwise central portion of the zippered fly is pressed as in the above-described clipping device, if the feeding speed of the zippered fly is increased to some extent, the widthwise edge portion of the zippered fly is guided between the presser foot of the sewing machine and the table in a state of being lifted from the upper surface of the table, thereby adversely affecting the hem. In particular, the above-described hemming device for a zipper-equipped fabric is used for hemming while rotating the zipper-equipped fabric, and therefore, centrifugal force is applied to the zipper-equipped fabric when the zipper-equipped fabric is rotated. Further, the edge of the zipper-equipped fly is likely to float from the upper surface of the table due to the centrifugal force.

In addition, there are drapes that differ in width and length according to the desires of customers. Therefore, there are many kinds of zippered fabrics. Therefore, the position in the width direction and the range in the length direction to press the zippered fly at the time of hemming differ depending on the type of the zippered fly. In this way, it is desirable to be able to compress the inside of the edge portion of the zippered drape in response to as many kinds of zippered drapes as possible.

In addition, the material clamping device does not have a structure for coping with the shielding cloth with different widths and lengths.

The present invention has been made in view of the above circumstances, and an object thereof is to enable the inner side of the edge portion of a zipper-equipped fly to be compressed against a fly of a type different in at least one of width and length.

The invention relates to a material clamping system for a hemming device of a covering cloth with a zipper. The hemming device for a zipper-equipped fabric cover on the premise of the present invention uses the zipper-equipped fabric cover as a sewing object. The zipper-equipped fabric cover is formed by laminating a zipper on the upper side of the central part of the fabric cover in the width direction, which is the direction parallel to the transverse edges, and the longitudinal direction of the zipper is parallel to the longitudinal edges, and the fabric cover is provided with a flange formed by joining the longitudinal edges and the transverse edges extending in the crossing direction by curved edges.

Further, the material clamping system of the present invention includes: a material clamping device which presses the zipper-equipped blanket against the workbench when the zipper-equipped blanket is hemmed by the sewing machine and is conveyed above the workbench by the conveying device in a state of pressing the zipper-equipped blanket; a length detector that detects a length of the zipper-equipped fabric in a direction parallel to the longitudinal side; and a control device which controls the material clamping device.

The material clamping device is provided with: a horizontal clamp for pressing the inner side of the horizontal edge of the covering cloth with the zipper; a bending jig for pressing an inner side of at least a bent side of a flange of the zipper-equipped fly; a longitudinal clamp, which is used for controlling the action of pressing the inner side of the longitudinal edge of the covering cloth with the zipper; and a connecting part which connects the vertical clamp, the horizontal clamp and the bending clamp with the conveying device. The operation of the vertical jig is controlled based on the length of the zipper-equipped fabric, which is a detection result of the length detector.

The number of the vertical jigs in the material clamping device is arbitrary, but in order to cope with plural kinds of zippered veils having different lengths, it is desirable to have the following configuration.

The material clamping device is provided with a plurality of vertical clamps which are arranged in the length direction of the covering cloth with the zipper.

The bending jig may be used regardless of whether or not only the inner side of the bent side of the edge of the zipper-equipped fly is pressed, but in order to allow the clipping system to cope with a wider variety of zipper-equipped flies having different lengths, it is desirable to have the following configuration.

That is, the bending jig compresses a range from the inside of the bent side to the inside of the longitudinal side in the edge of the zipper-equipped blanket.

The above described clipping system can cope with the kinds of the zippered scrip having different lengths, but in order to cope with the kinds of the zippered scrip having different widths, it is desirable to have the following configuration.

That is, the clipping system includes a width detector that detects the width of the zipper-equipped fly. The connecting portion further includes: a1 st connecting part for connecting the conveying device and the horizontal clamp; a 2 nd connecting part for connecting the vertical clamp and the bending clamp; and a traversing device which moves the 2 nd connecting part relative to the 1 st connecting part in the width direction of the covering cloth with the zipper. The traverse device controls the position of the 2 nd connecting part relative to the 1 st connecting part based on the detection result of the width detector.

The material clamping device may be provided with another jig between the horizontal jig and the bending jig, but is desirably configured as follows in order to press the inner side of the edge of the zippered drape as much as possible even if the zippered drape is of a type having a different width.

That is, the material clamping device includes an auxiliary jig between the horizontal jig and the bending jig, and the operation of the auxiliary jig for pressing the inner side of the edge of the zipper-equipped fly is controlled. The operation of the auxiliary jig is controlled based on the detection result of the width detector.

Effects of the invention

The material clamping system of the invention uses the length detector to detect the length of the covering cloth with the zipper, and controls the action of the longitudinal clamp based on the detection result, therefore, the inner side of the edge of the covering cloth with the zipper can be pressed corresponding to the covering cloth with the zipper with different lengths.

In the clipping system according to the present invention, when the clipping device includes a plurality of vertical jigs, the inner side of the edge of the zippered fly can be pressed against a wider variety of zippered flies having different lengths than in the case where the clipping device includes one vertical jig.

In the clipping system of the present invention, when the bending jig presses the range from the inside of the bent side to the inside of the longitudinal side in the edge of the zippered patch, it is possible to cope with a wider variety of zippered patches having different lengths.

In the clipping system according to the present invention, if the width detector is provided and the connecting portion is provided with the lateral moving device, the lateral moving device controls the position of the 2 nd connecting portion with respect to the 1 st connecting portion of the connecting portion in the width direction of the zippered patch based on the detection result of the width detector, and therefore, it is possible to cope with the types of the zippered patches having different widths.

In the clipping system according to the present invention, when the auxiliary jig is provided between the horizontal jig and the bending jig, the inner side of the edge of the zippered patch can be more compressed than the case where only the horizontal jig and the bending jig are provided.

Detailed Description

The hemming device of the zipper-equipped blanket takes the zipper-equipped blanket as a sewing object. As shown in fig. 10, the zipper-equipped blanket 1 is a part of the elongated object 1A before becoming a sewing object. The longitudinal object 1A is formed by continuously arranging a plurality of zippered fabrics 1 in the longitudinal direction thereof. The stringer 1A is cut at a position between the adjacent zippered scrims 1, thereby forming the zippered scrims 1.

In other words, the elongated article 1A includes the elongated fastener chain 2A and the plurality of sheets 3, and the plurality of sheets 3 are stacked on the lower side of the fastener chain 2A and sewn to the fastener chain 2A in a state of being arranged in the longitudinal direction of the fastener chain 2A. The method of arranging the masking cloths 3 may be in a state of being spaced apart in the longitudinal direction as shown in the drawing, and may be arranged adjacently in the longitudinal direction, although not shown.

The fastener chain 2A has a plurality of fasteners 2 arranged continuously in the longitudinal direction thereof. Then, the fastener chain 2A is cut at a position between the adjacent fasteners 2, thereby forming the fastener 2. By cutting in this manner, the zipper-equipped fly 1 in which the zipper 2 and the fly 3 below the zipper 2 are integrated is formed.

The slide fastener 2 is an elongated member. Therefore, the slide fastener 2 includes a longitudinal direction and a width direction orthogonal to each other in addition to the thickness direction. The length of the slide fastener 2 in the width direction is shorter than the length of the slide fastener 2 in the longitudinal direction.

Further, the slide fastener 2 includes: a pair of belts 4, 4 arranged to face each other in the width direction; a pair of element rows 5, 5 fixed to the widthwise opposite side edge portions of the pair of belts 4, 4; a slider 6 that is guided so as to be movable relative to the pair of element rows 5, 5 and opens and closes the pair of element rows 5, 5; and a1 st stop 7 and a 2 nd stop 8 that stop movement of the slider 6 at both ends in the longitudinal direction of the pair of element rows 5, 5.

One of the pair of belts 4, 4 is sewn with a sewing thread 4a to the cloth 3 along the longitudinal direction of the opposite side edge portion in the width direction, and the other of the pair of belts 4, 4 is not sewn to the cloth 3 but is merely superposed on the cloth 3. Hereinafter, the band 4 sewn by the sewing thread 4a may be referred to as a sewing-side band 4, and the band 4 not sewn may be referred to as a non-sewing-side band 4.

The 1 st stop 7 is for abutting against the slider 6 when the slider 6 is moved in a direction in which the pair of element rows 5, 5 are opened. In addition, the 1 st stop 7 connects the pair of belts 4, 4.

The 2 nd stop 8 is for abutting against the slider 6 when the slider 6 is moved in a direction to close the pair of element rows 5, 5. In addition, the 2 nd stop 8 is fixed with respect to one of the belts 4.

The element row 5 is formed of a plurality of elements arranged in a row at intervals along the side edge portion of the tape 4, or is formed of a monofilament bent in a coil shape or a zigzag shape and having element portions corresponding to the plurality of elements and continuous.

The cloth 3 is a soft cloth. In the present embodiment, the fabric 3 has a rectangular shape and includes two sides facing each other in one direction and two sides facing each other in the other direction. More specifically, the fabric 3 is a long and thin rectangular shape and includes two long sides and two short sides. The cloth 3 has 4 corners. As shown in fig. 1, the fabric 3 is cut into a smoothly curved shape from 1 of the 4 corners before being hemmed (edge overlooked).

The cut corner of the 4 corners is a corner on the side of the direction in which the sewing-side tape 4 sewn to the upper slide fastener 2 is located in the extending direction of the short side (hereinafter referred to as the short side direction), and is a corner on the side in which the 1 st stop 7 is located in the extending direction of the long side (hereinafter referred to as the long side direction). Not only the fabric 3 but also the sewing-side tape 4 is cut together with the fabric 3.

The smoothly curved shape corresponds to a locus of a circle 1/4, that is, an arc shape in the illustrated example. Although not shown, the smoothly curved shape also includes a locus of 1/4 corresponding to an ellipse, that is, an elliptical arc shape. Incidentally, the centers of the circle and the ellipse are located on the side of the shade cloth 3, and the tangent lines of the arc-shaped end points of the arc-shaped and the ellipse are the long sides and the short sides located on both sides thereof.

Hereinafter, terms regarding the edge of the mask 3 are determined as follows. The smoothly curved shape portion is referred to as a curved side 3 b. A long side that is a tangent to one end point of the curved side 3b is referred to as a longitudinal side 3 c. The short side of the tangent line at the other end of the curved side 3b is referred to as a lateral side 3 a. Therefore, a part of the edge of the cloth 3 is smoothly joined by the curved side 3b to the lateral side 3a and the longitudinal side 3c extending straight in the intersecting direction, more specifically, in the orthogonal direction. The edge of the cloth 3 is formed by a long side, a short side, a longitudinal side 3c, a lateral side 3a, and a curved side 3 b.

In the state before the corner cutting, the length of the patch 3 in the longitudinal direction is shorter than the length of the slide fastener 2 in the longitudinal direction, and the length of the patch 3 in the short side direction is longer than the length of the slide fastener 2 in the width direction. Since the slide fastener 2 is stacked on the middle portion in the short side direction of the patch 3, both end portions in the short side direction (extending direction of the lateral side 3a) of the patch 3 protrude beyond the slide fastener 2 on both sides in the width direction thereof. The slide fastener 2 has both longitudinal ends extending beyond the covering 3 in both longitudinal directions. The width direction of the slide fastener 2 is parallel to the lateral side 3a, and is the width direction of the zipper-equipped fabric 1. The longitudinal direction of the slide fastener 2 is parallel to the longitudinal side 3c, and is the longitudinal direction of the zipper-equipped fabric 1. Incidentally, since the excess length of the 1 st stop 7 side is shorter than the excess length of the 2 nd stop 8 side in the longitudinal direction of the slide fastener 2, one end in the longitudinal direction of the pair of tapes 4, 4 is substantially at the same position as one end in the longitudinal direction of the patch 3 (one end on the lateral side 3a side) with respect to the 1 st stop 7 side. The longitudinal direction of the cloth 3 (the direction in which the longitudinal side 3c extends) coincides with the longitudinal direction of the slide fastener 2. The parallelism may be a degree that can be judged to be parallel by visual observation, and is not strictly parallel.

What hems the above-described zippered patch 1 is a hemming device for the zippered patch 1 including the first embodiment of the clipping system of the present invention. As shown in fig. 10, the hemming device of the zipper-equipped fabric 1 according to the first embodiment includes: a conveying device (not shown) for the long article 1A, which conveys the long article 1A in the longitudinal direction of the long article 1A; a cutter device 11 for cutting the conveyed longitudinal object 1A at a position between the adjacent zippered veils 1, 1; a gripper device 12 for gripping and carrying the zipper-equipped fabric 1 separated from the longitudinal object 1A; a table 13 on which the zipper-equipped fabric 1 conveyed by the jig device 12 is placed; a length detector 14 that detects the length of the zipper-equipped fabric 1 (the length parallel to the longitudinal side 3 c); a width detector 15 that detects the width (length parallel to the lateral side 3a) of the zipper-equipped fabric 1; a posture maintaining device 16 for maintaining the posture of the zipper-equipped fabric 1 on the workbench 13 for hemming; a sewing machine 17 for performing hemming of the fabric 3 and provided on the table 13; and a conveying device 18 for the posture maintaining device 16, which conveys the posture maintaining device 16. The hemming device of the fastener stringer 1 includes a control device 19 for controlling various devices.

The table 13 has a flat upper surface. The table 13 has a curved shape in plan view, more specifically, an L shape, and includes two plate portions 13a and 13b extending in orthogonal directions. A sewing machine 17 is provided at a portion where the two plate portions 13a and 13b intersect. In addition, a through hole 13c penetrating in the thickness direction of the plate is formed in a portion of the table 13 where the sewing machine 17 is provided, and a part of a conveying tooth, not shown, which is a conveying portion of the cover 1 for conveying the slide fastener is disposed in the through hole 13 c. The conveying teeth convey the tape 1 of the slide fastener in accordance with the vertical movement of the sewing machine needle, not shown, of the sewing machine 17.

Thereafter, the direction is determined as follows. The directions orthogonal to each other in the L shape (extending directions of the two plate portions 13a and 13 b) when the table 13 is viewed in plan are two orthogonal linear directions. One of the linear directions is defined as a front-rear direction, and the other linear direction is defined as a left-right direction. The front-rear direction is the up-down direction in fig. 10. The front direction is the lower direction in fig. 10, and the rear direction is the upper direction in fig. 10. The left-right direction is the left-right direction in fig. 10. The left direction is the left direction in fig. 10, and the right direction is the right direction in fig. 10.

Although not shown in detail, the gripper device 12 includes a gripper for gripping (holding) the zipper-equipped fly 1 and a moving device for moving the gripper. Further, the moving device of the jig device 12 includes: a jig body capable of gripping and releasing the zipper-equipped fabric 1; a motor as a power source that drives the jig main body; and a control circuit that controls rotation of the motor. The detector for detecting the rotation angle of the motor in the control circuit is an encoder, and functions as a length detector 14 for detecting the length of the longitudinal edge 3c of the zipper-equipped fabric 1. Disposed between the jig device 12 and the table 13 is a width detector 15.

The width detector 15 detects the presence or absence of the zipper-equipped fly 1. In the present embodiment, one width detector 15 is provided. More specifically, the width detector 15 is, for example, a reflection type detector, and is provided at a position lower than the upper surface of the table 13. Thus, when the zipper-equipped fabric 1 is moved toward the table 13, the width detector 15 detects the presence or absence of the zipper-equipped fabric 1.

The sewing machine 17 includes: a sewing machine presser foot (not shown) which is supported above the table 13 so as to be movable up and down and which presses the fastener-attached cover 1 in cooperation with the table 13; a sewing machine needle (not shown) that moves up and down; a conveying tooth (not shown) for conveying the blind cloth 1 of the slide fastener; and a cutter 17b which is arranged around the presser foot of the sewing machine in a plan view and is used for cutting the covering cloth 1 with the zipper.

The covering portion 66 is a part of a cover plate 67 extending in the front-rear direction. That is, the cover plate 67 is formed by connecting all the covering portions 66 in the front-rear direction. The groove forming portion 65 is also a part of the groove block 68 extending in the front-rear direction. That is, the groove block 68 is also formed by the groove forming portion 65 being continuous in the front-rear direction. The assembling portion 59 is integral with the pocket block 68.

The assembly portion 59 and the channel block 68 are a plate 71, more specifically a plate 71 with a step. The upper surface of the plate 71 is formed so that the left side protrudes upward from the right side, and the lower surface of the plate 71 is formed as a flat surface. The lower surface portion of the plate 71 serves as an assembling portion 59 and is placed on the upper surface of the sub-plate 31.

The guide mechanism 81 is a block in which a through hole 81h is formed to movably guide the 3 rd connecting rod 79 c. The blocks of the guide mechanism 81 have the following shapes: the insertion direction of the insertion hole 81h is aligned with the moving direction of the 3 rd connecting rod 79c (the extending and contracting direction of the piston rod 78 a), and the inner surface of the insertion hole 81h is made to correspond to the outer peripheral surface of the 3 rd connecting rod 79c (a shape slightly larger than the outer peripheral surface of the 3 rd connecting rod 79 c).

More specifically, the guide mechanism 81 is constituted by left and right guide blocks 81a and 81 b. The left and right guide blocks 81a, 81b are fixed to the left end of the front surface of the lateral plate portion 44 b.

The distal end portion of the lower piece portion 84c protrudes leftward from the slit 48b (lateral pressing portion 48), and is inserted between the non-sewing side belt 4 and the patch 3.

As shown in fig. 6 and 7, the upper portion of the upper piece portion 84a protrudes upward from the pair of arm pieces 86d and 86 d. A rotating mechanism 88 rotates the insertion piece 84 by a predetermined angle by the upper portion of the upper piece 84 a.

The rotation mechanism 88 includes: a shaft 91 that is bridged over the pair of arm pieces 86d, 86d in a state of penetrating the upper piece portion 84a of the insertion piece 84, and rotatably supports the insertion piece 84; an opposing block 92 fixed to the upper surface of the distal end portion (left end portion) of the rod main body 86c of the connecting rod 86b in a state where the right side is opposed to the upper portion of the upper piece portion 84 a; a compression coil spring 93 which is housed in a contracted state between the opposing block 92 and the upper piece portion 84 a; a press-fitting portion 94 that is fixed to the upper surface of the front portion of the spacer 89 and presses the upper piece portion 84a against the elastic force of the compression coil spring 93; and a restricting portion 95 that restricts the rotation of the insertion piece 84 toward the table 13 side against the elastic force of the compression coil spring 93 and is fixed to the lower surface of the tip end portion of the rod main body 86c of the connecting rod 86 b.

A hole 92a is formed in the left surface of the counter block 92, and the compression coil spring 93 is partially accommodated in the hole 92 a.

The press-fitting portion 94 includes: a rod-shaped portion 94a extending in the left-right direction in a state of covering the front portion of the upper surface of the spacer 89, the opposing block 92, and the upper portion of the insertion piece 84; a fixing portion 94b extending downward from a right end of the rod-shaped portion 94a and fixed to an upper surface of the partition 89; and a contact piece 94c extending downward from the left end of the rod-shaped portion 94a and configured to contact the upper portion of the upper piece portion 84 a.

The contact piece 94c is spaced apart from the upper piece portion 84a of the insertion piece 84 in the left direction in a state where the piston rod 85a of the cylinder device 85 is extended, and pushes the upper piece portion 84a of the insertion piece 84 in the right direction in a state where the piston rod 85a is contracted.

Controlling the various devices described above is a control device 19. The control device 19 controls the hemming device in the following order 1) to 8).

1) First, the control device 19 drives a conveying device for the long article 1A, not shown. The transport device transports the longitudinal object 1A in the longitudinal direction thereof, and directs the longitudinal object 1A toward the table 13.

2) Subsequently, the control device 19 drives the tool device 11. The cutter device 11 cuts the longitudinal object 1A between the adjacent zippered veils 1, 1.

3) Subsequently, the control device 19 drives the chuck device 12. The gripper device 12 grips the zipper-equipped fly 1 separated by the cutter device 11 and moves the zipper-equipped fly 1, and the zipper-equipped fly 1 is placed on the table 13. In detail, the clip device 12 places the zipper-equipped fly 1 on the rear portion of the plate portion 13a extending in the front-rear direction in the table 13.

3-1) at this time, the posture maintaining device 16 stands by at a position (initial position) on the side of the rear part of the table 13 and apart from the table 13. The control device 19 calculates the length of the zipper-equipped fabric 1 based on the detection result of the encoder (length detector 14) of the clamp device 12, controls the cylinder device 62 of the vertical clamp 58 of the vertical clamp group 26 based on the calculation result, and controls whether or not to move the position of the vertical pressing portion 61 to the position for pressing the zipper-equipped fabric 1. That is, when the length of the zippered patch 1 is such that the inner side of the longitudinal side 3c of the zippered patch 1 can be sufficiently compressed only by the bending jig 25, the control device 19 controls the cylinder devices 62 of the longitudinal jigs 58 so that the longitudinal pressing portions 61 of all the longitudinal jigs 58 are arranged at the standby position. On the other hand, when the length of the zippered patch 1 is a length at which the inner side of the longitudinal side 3c of the zippered patch 1 cannot be sufficiently compressed only by the bending jig 25, the control device 19 controls the cylinder devices 62 of the longitudinal jigs 58 so that the longitudinal pressing portions 61 required in all the longitudinal jigs 58 are disposed at the operating positions.

3-2) when the zipper-equipped fly 1 is moved toward the table 13, the presence or absence of the zipper-equipped fly 1 is detected by the width detector 15 on the upstream side of the table 13. When the width detector 15 detects the zippered cloth 1, the control device 19 determines that the zippered cloth 1 has a wide width, controls the cylinder device 73 of the traverse device 32 of the clipping device 21 so that the vertical jig group 26 and the bending jig 25 are arranged at the wide-width position, and controls the cylinder device 78 of the auxiliary jig 28 so that the auxiliary pressing portion 77 of the auxiliary jig 28 is arranged at the operating position. When the width detector 15 does not detect the zippered fabric 1, the control device 19 determines that the zippered fabric 1 is of a narrow type, controls the cylinder device 73 of the traverse device 32 of the material clamping device 21 so that the vertical jig group 26 and the bending jig 25 are arranged at the narrow width position, and controls the cylinder device 78 of the auxiliary jig 28 so that the auxiliary pressing portion 77 of the auxiliary jig 28 is arranged at the standby position.

In this manner, the control device 19 controls the cylinder device 73 of the lateral-movement device 32 based on the detection result of the width detector 15, thereby controlling the position (position in the left-right direction) of the 2 nd coupling part 31 with respect to the 1 st coupling part 29, further controlling the operation of the vertical jig 58, and further controlling the cylinder device 78 of the auxiliary jig 28, that is, the operation of the auxiliary jig 28 based on the detection result of the width detector 15.

4) Subsequently, the control device 19 drives the articulated robot 18. The articulated robot 18 moves the position holding device 16 onto the zipper-equipped fly 1 and then lowers the device, whereby the inside of the edge of the zipper-equipped fly 1 is pressed against the table 13 by the clipping device 21 of the position holding device 16, and the clipping device 21 and the table 13 cooperate to clip the zipper-equipped fly 1. At least the lateral pressing portion 48 and the curved pressing portion 55 press the inner side of the edge of the zipper-equipped drape 1 against the table 13. At this time, the insert piece 84 of the tape separating device 22 of the posture maintaining device 16 is placed on the cover 3 of the zipper-equipped cover 1 at a position located laterally (right side in fig. 7 a) with respect to the non-sewing side tape 4, that is, at the standby position. The restricting portion 95 abuts against the lower piece portion 84c of the insertion piece 84, and restricts the insertion piece 84 from rotating by the restoring force of the compression coil spring 93.

5) The control unit 19 then drives the belt away from the cylinder unit 85 of the unit 22, retracting the piston rod 85 a. Then, as shown in fig. 7 (B), the lower piece portion 84c of the insert piece 84 is inserted between the mask 3 and the non-sewing side tape 4. When the piston rod 85a is further contracted, as shown in fig. 7 (C), the touching piece 94C touches the upper piece portion 84a of the insertion piece 84 and is pushed in to the right side, and the insertion piece 84 is rotated by an angle corresponding to the amount of pushing in, so that the non-sewing side belt 4 is lifted up and the sewing machine 17 can sew the inside of the edge of the slide fastener cover 1.

6) Next, the controller 19 drives the articulated robot 18 to feed the posture maintaining device 16 in a state in which the zipper-equipped fabric 1 before hemming is sandwiched toward the sewing machine 17, and thereafter, the controller 19 drives the sewing machine 17 while driving the articulated robot 18 to hem the edge portion of the zipper-equipped fabric 1 in the order of the lateral side 3a, the curved side 3b, and the longitudinal side 3c by the sewing machine 17. More specifically, the conveyance for before-hemming, which linearly conveys the position holding device 16 toward the sewing machine 17, and the conveyance for hemming, which conveys the position holding device 16 in accordance with the shape of the edge of the zipper-equipped blanket 1, are continuously performed. In the hemming conveyance, conveyance corresponding to the shape of the curved side 3b is conveyance in a rotational direction such that a substantially semicircular shape is drawn in a plan view.

Before the conveyance in the rotational direction, the sewing machine 17 stitches the lateral side 3 a. During the transport in the rotational direction, the sewing machine 17 cuts the 1 corner of the fabric 3 together with the sewing-side belt 4 by the cutter 17b of the sewing machine 17, thereby forming a curved edge 3b, and the fabric 3 is sewn together with the sewing-side belt 4 along the curved edge 3 b. After the conveyance in the rotational direction, the sewing machine 17 stitches the longitudinal edge 3 c.

7) After the hemming, the controller 19 stops the sewing machine 17, drives the articulated robot 18 to return the attitude keeping device 16 to the initial position, and drives the cylinder device 85 of the belt detaching device 22 to return the insert piece 84 to the standby position.

8) By repeating the steps 1) to 7) above, the hemming device continuously hems the zipper-equipped fabric 1.

The material clamping system according to the first embodiment is formed by the control device 19, the width detector 15, the length detector 14, and the material clamping device 21 described above. Further, in the clipping system according to the first embodiment, the length of the zipper-equipped fabric 1 is detected by the length detector 14, and the operation of the longitudinal jig group 26 is controlled based on the detection result, so that the inner side of the edge (hem portion) of the zipper-equipped fabric 1 can be pressed in response to the types of zipper-equipped fabrics 1 having different lengths.

Further, in the clipping system of the first embodiment, since the clipping device 21 includes the vertical jig group 26 (a plurality of vertical jigs 58), it is possible to press the inner side of the edge of the zippered patch 1 in response to a wider variety of zippered patches 1 having different lengths than in the case where the clipping device 21 includes one vertical jig 58.

In the clipping system according to the first embodiment, the bending jig 25 is used to press the range from the inside of the bent side 3b to the inside of the longitudinal side 3c in the edge of the zipper-equipped drape 1, and therefore, depending on the length of the longitudinal side 3c of the zipper-equipped drape 1, the inside of the longitudinal side 3c of the zipper-equipped drape 1 can be pressed only by the bending jig 25, and in the case where the inside of the longitudinal side 3c of the zipper-equipped drape 1 cannot be pressed only by the bending jig 25, the inside of the longitudinal side 3c of the zipper-equipped drape 1 is pressed by the longitudinal jig 58 required in the longitudinal jig group 26. That is, the clipping system of the first embodiment can cope with a wider variety of zippered veils 1 having different lengths.

Further, since the clipping system of the first embodiment includes the width detector 15 and the connecting portion 27 includes the lateral moving device 32, the lateral moving device 32 controls the position of the 2 nd connecting portion 31 with respect to the 1 st connecting portion 29 of the connecting portion 27 in the width direction of the zippered patch 1 based on the detection result of the width detector 15, and thus, it is possible to cope with the types of the zippered patches 1 (two types of zippered patches 1) having different widths.

In addition, the clipping system of the first embodiment is provided with the auxiliary jig 28 between the horizontal jig 24 and the bending jig 25, and therefore, in the case of the wide-width zippered patch 1, the inner side of the edge of the zippered patch 1 can be more compressed than the case of having only the horizontal jig 24 and the bending jig 25.

The present invention is not limited to the above-described embodiments, and can be appropriately modified within a scope not departing from the gist thereof. The width detector 15 is used to detect the presence or absence of the zipper-equipped fly 1 in the above-described embodiment, that is, to detect the width of the zipper-equipped fly 1 in two stages, but the present invention is not limited thereto, and may be a detector that actually detects the width of the zipper-equipped fly 1.
