Description

  The present invention relates to a cloth bonding apparatus for bonding cloths by applying an adhesive to the cloths while transferring the cloths.

  The cloth bonding apparatus bonds a cloth with an adhesive instead of sewing the cloth with a needle and a sewing thread. The cloth bonding apparatus includes a transfer mechanism that transfers a cloth while pressing the cloth, and a nozzle that discharges an adhesive. The nozzle applies an adhesive between the fabrics being transferred that are oppositely arranged. The transfer mechanism transfers the fabric while pressing the fabric, and the fabrics adhere to each other. Since the bonded fabric does not use sewing threads, unevenness does not occur on the fabric.

  The cloth bonding apparatus described in Patent Document 1 includes a guide mechanism on the upstream side in the cloth transfer direction with respect to the nozzle. The guide mechanism is in a state where the vicinity of the edge of the cloth (hereinafter referred to as “edge part”) is bent, and guides the edge of the cloth bent to the nozzle and the transfer mechanism. The nozzle discharges the adhesive inside the edge of the cloth, and the transfer mechanism presses the edge of the cloth. Therefore, the cloth bonding apparatus can perform a process of bonding the edge of the folded cloth (hereinafter referred to as “hem process”).

As shown in FIG. 9, the fixed portion 822 has a substantially rectangular plate shape in plan view and has a longitudinal direction in the front-rear direction. As shown in FIG. 10, the lower surface of the fixing portion 822 is substantially the same height as the lower surface of the base portion 71 and is in contact with the upper surface of the pedestal portion 2 (see FIG. 1). As shown in FIG. 9, the fixed portion 822 is positioned on the left side of the base portion 71 in a state where the posture of the first guide mechanism 70 is switched to the first posture. The fixing portion 822 is provided with two screw holes not shown. The two screw holes are aligned with the fixing portion 822 in the front-rear direction.

  The guide part 83 includes a fixing part 831, an extension part 832, and a cover part 86. As shown in FIG. 9, the fixing portion 831 has a substantially rectangular shape in plan view, and has substantially the same shape as the fixing portion 822 of the protruding portion 82. The fixing portion 831 overlaps the upper side of the fixing portion 822. The fixing portion 831 is provided with a long hole 85 extending in the front-rear direction substantially at the center. The two screws 84, 84 are inserted through the elongated hole 85. The two screws 84 and 84 are fastened in the screw holes of the fixing portion 822. An operator can use one of a plurality of different types of guide portions 83 attached to the protruding portion 82.

  The extending portion 832 has a plate shape extending leftward from the fixed portion 831. As shown in FIGS. 9 and 10, the left end of the extending portion 832 is the right end portion of the nozzle 51, that is, the end portion of the nozzle 51 in the extending direction, in a state where the posture of the first guide mechanism 70 is switched to the first posture. Of these, it is located on the right side of the end opposite to the side connected to the nozzle support 43. As shown in FIG. 10, the height of the lower surface of the extending portion 832 and the lower surface of the nozzle 51 are substantially the same.

  A cover 86 is provided at the left end of the extended portion 832. The cover portion 86 includes a first cover portion 861 and a second cover portion 862. As shown in FIG. 10, the first cover portion 861 is provided at the left end of the extending portion 832. The first cover portion 861 has a plate shape extending upward from the left end of the extending portion 832. As shown in FIG. 9, in a state where the posture of the first guide mechanism 70 is switched to the first posture, both surfaces of the first cover portion 861 face in the left-right direction. The first cover portion 861 extends in the front-rear direction, that is, parallel to the cloth transfer direction. The front end position of the first cover portion 861 substantially coincides with the front end position of the nozzle 51. The rear end position of the first cover portion 861 is located on the rear side of the rear end position of the nozzle 51. The first cover portion 861 covers the entire right side surface 513 of the nozzle 51.

  As shown in FIG. 10, the second cover 862 extends horizontally from the upper end of the first cover 861 to the left. A joint portion between the first cover portion 861 and the second cover portion 862 is curved in an arc shape. In a state where the posture of the first guide mechanism 70 is switched to the first posture, the second cover portion 862 extends in the extending direction of the nozzle 51. The second covering portion 862 covers the upper end 511 side of the nozzle 51, that is, the right end portion of the nozzle 51 opposite to the lower surface 512 side provided with the discharge port 53. The length of the second cover portion 862 in the extending direction is shorter than the length of the nozzle 51 in the extending direction. The left end position of the second cover portion 862 is located at the approximate center of the extending direction of the nozzle 51. The second cover 862 does not cover the entire upper surface of the nozzle 51.

  As shown in FIGS. 8 and 9, the rear side of the second cover part 862 includes a notch part 864 that is notched in an arc shape in plan view on the first cover part 861 side. As shown in FIG. 9, the upper transfer roller 17 (see FIG. 1) is located in a region cut out by the cutout portion 864 in a state where the posture of the first guide mechanism 70 is switched to the first posture. The notch 864 avoids contact between the second cover 862 and the upper transfer roller 17.

  As shown in FIG. 10, a gap is formed between the nozzle 51 and the cover 86 in a state where the posture of the first guide mechanism 70 is switched to the first posture. The gap extends upward along the right side surface 513 and the first cover portion 861 of the nozzle 51, the joint portion between the right side surface 513 and the top surface 511 of the nozzle 51, and the joint portion between the first cover portion 861 and the second cover portion 862. Is curved to the left and extends to the left along the upper surface 511 and the second cover 862 of the nozzle 51.

  The hem process will be described with reference to FIGS. When the operator performs the hem process, the operator moves from the upstream side in the transfer direction (the lower side in FIG. 11, the front side in FIG. 12) to the downstream side (the upper side in FIG. 11, FIG. 12). Toward the back side) of the cloth 100 is guided in the vicinity of the edge 101. Hereinafter, the bent portion of the cloth 100 is referred to as a “bent portion 102”, and the folded portion of the cloth 100 is referred to as an “edge portion 103”. An end portion of the edge portion 103 of the cloth 100 on the downstream side in the transfer direction is disposed in a gap between the nozzle 51 and the cover portion 86. The operator abuts the edge 101 of the cloth 100 against the abutment portion 64 of the second guide mechanism 60.

  As shown in FIG. 12, the cloth 100 extends rightward from the edge 101 that contacts the contact portion 64 through a gap between the nozzle 51 and the second cover portion 862. The edge 103 of the cloth 100 is placed on the upper surface 511 of the nozzle 51. The cloth 100 bends downward in the gap between the joint portion of the first cover portion 861 and the second cover portion 862 and the nozzle 51, and passes through the gap between the right side surface 513 of the nozzle 51 and the first cover portion 861. Extend to. Furthermore, the cloth 100 bends leftward and extends leftward through a gap between the pedestal 2 and the nozzle 51. The lower part of the nozzle 51 of the cloth 100 is placed on the belt 20. The nozzle 51 and the cover portion 86 hold the cloth 100 in a state where the cloth 100 is bent at the bent portion 102. Since the cover part 86 covers the bent part 102 of the cloth 100 from the outside, the cloth 100 does not return to the original straight state.

  Note that the length of the second cover portion 862 in the left-right direction, that is, the extension direction of the nozzle 51 is shorter than the length of the nozzle 51 in the extension direction. The second cover 862 does not cover the entire upper surface of the nozzle 51. Therefore, since the second cover 862 does not block the field of view of the cloth 100 disposed on the upper surface of the nozzle 51, the operator can perform the bonding operation while visually checking the cloth 100 passing through the upper surface of the nozzle 51.

  The operator can move the guide portion 83 left and right by loosening the screw 81 (see FIG. 9). A plurality of types of nozzles 51 having different lengths in the extending direction can be exchanged. Therefore, the operator can adjust the length of the nozzle 51 in accordance with the length of the nozzle 51 by moving the guide portion 83 in the left-right direction. Note that the operator can use the first cover portion 861 by attaching any one of the plurality of guide portions 83 having different vertical lengths to the protruding portion 82. By changing the guide portion 83, the size of the gap between the upper surface 511 of the nozzle 51 and the second cover portion 862 changes. Therefore, the operator adjusts the position of the guide part 83 in the left-right direction, and attaches the guide part 83 according to the thickness of the cloth 100 to the protruding part 82 to use the cloth 100 with various thicknesses. Can be held in a bent state at the bent portion 102.

  The contact portion 64 holds the length (width) of the edge portion 103 of the cloth 100 in the left-right direction substantially the same as the length from the right end of the nozzle 51 to the contact portion 64. The operator can move the contact portion 64 left and right by loosening the screw 612. Therefore, the operator can adjust the width of the edge portion 103 of the cloth 100 as appropriate by adjusting the position of the contact portion 64 in the left-right direction.

  The second support portion 62 that supports the contact portion 64 extends in the left-right direction along the rear side surface of the nozzle support portion 43. The second support part 62 does not block the view of the cloth 100. Therefore, the operator can perform the bonding operation while visually recognizing the cloth 100 well.

  The operator operates the cloth bonding apparatus 1 and starts the rotation of the upper transfer roller 17 and the belt 20. The cloth 100 placed on the belt 20 moves backward. As shown in FIG. 11, the nozzle 51 and the cover portion 86 guide the cloth 100 to the upper transfer roller 17 disposed behind the nozzle 51 in a state where the cloth 100 is bent at the bending portion 102. Since the cover 86 is provided at a position covering the nozzle 51, the cover 86 can hold the cloth 100 in a folded state at the position of the nozzle 51. Therefore, the cover portion 86 can prevent the edge portion 103 of the cloth 100 from being displaced in the direction intersecting the transport direction at the position of the nozzle 51. The right side surface of the contact portion 64 is parallel to the transfer direction of the cloth 100 and is a smooth plane. Therefore, the edge 101 of the cloth 100 moves straight along the transfer direction while contacting the right side surface of the contact portion 64.

  Simultaneously with the start of rotation of the upper transfer roller 17 and the belt 20, the gear pump starts driving. The gear pump supplies the adhesive stored in the storage chamber 21 (see FIG. 1) to the nozzle 51. The discharge ports 53 and 54 (see FIG. 7) of the nozzle 51 discharge the adhesive to the inside of the edge 103 of the cloth 100. Since the cloth 100 bends at the right end of the nozzle 51, the positional relationship between the cloth 100 and the nozzle 51 is constant. Therefore, the adhesive adheres stably to the bent portion 102 of the cloth 100 at a certain position. In addition, when performing the hem process, the cloth bonding apparatus 1 desirably discharges the adhesive also to the inside of the bent portion 102 of the cloth 100. On the other hand, since the discharge port 54 is provided on the right side surface 513 of the nozzle 51, the adhesive can be reliably discharged to the inside of the bent portion 102 of the cloth 100.

  The rear end of the first cover portion 861 is located behind the rear end of the nozzle 51. The rear end of the first cover portion 861 is disposed behind the front end of the upper transfer roller 17. Since the notch 864 (see FIG. 8) is provided in the second cover 862, the second cover 862 does not contact the upper transfer roller 17. The rear end of the contact portion 64 is disposed on the rear side of the rear end of the nozzle 51. The rear end of the abutting portion 64 is disposed behind the front end of the upper transfer roller 17. Since the notch portion 642 (see FIG. 4) is provided in the contact portion 64, the contact portion 64 does not contact the front end portion 15 that supports the upper transfer roller 17. By extending the first cover 861 and the contact portion 64 to the vicinity of the upper transfer roller 17, the edge 103 of the cloth 100 intersects the transfer direction until the cloth 100 that has passed through the nozzle 51 reaches the upper transfer roller 17. Can be reliably prevented from shifting in the direction of movement.

  The edge portion 103 of the cloth 100 passes below the extending portion 65 and reaches the upper transfer roller 17. The upper transfer roller 17 and the belt 20 sandwich the cloth 100 therebetween. The extending portion 65 suppresses the upward lifting of the edge portion 103 of the cloth 100. Therefore, the extending portion 65 can appropriately guide the edge portion 103 of the cloth 100 toward the upper transfer roller 17. In addition, since the shape of the extending part 65 is a rod shape, the visual field of the cloth 100 passing under the extending part 65 is not obstructed. Therefore, the worker can perform the bonding work while visually recognizing the edge portion 103 of the cloth 100.

  The upper transfer roller 17 and the belt 20 rotate, and the cloth 100 moves from the upstream side to the downstream side. The nozzle 51 and the cover 86 guide the edge 103 of the cloth 100 to the upper transfer roller 17 in a state where the cloth 100 is bent at the bent portion 102. The upper transfer roller 17 and the belt 20 sandwich the edge portion 103 of the cloth 100, and the edge portion 103 of the cloth 100 is folded and bonded. Since the cover part 86 is provided in the position which covers the nozzle 51, the cover part 86 can suppress that the edge part 103 of the cloth 100 shifts | deviates to the direction which cross | intersects the conveyance direction at the position of the nozzle 51. The upper transfer roller 17 and the belt 20 are appropriately bonded by bending the cloth 100 at the bent portion 102. Therefore, the quality of adhesion by the hem process is improved.

  As described above, in the cloth bonding apparatus 1, the positions of the first cover portion 861 and the second cover portion 862 in the front-rear direction substantially coincide with the nozzle 51. The first cover portion 861 and the second cover portion 862 can be in a state where the edge portion 103 of the cloth 100 is folded at the position of the nozzle 51. Therefore, the cloth bonding apparatus 1 can prevent the edge 103 of the cloth 100 from shifting in the direction intersecting the transfer direction at the position of the nozzle 51 when performing the hem process of bonding the edge 103 of the cloth 100. The cloth bonding apparatus 1 can make the width of the edge 103 of the cloth 100 constant by bringing the edge 101 of the cloth 100 into contact with the contact part 64. Therefore, the cloth bonding apparatus 1 can stably adhere the adhesive to the bent portion 102 of the cloth 100 at a certain position. The extending portion 65 suppresses the upward lifting of the edge portion 103 of the cloth 100. Therefore, the extending portion 65 can appropriately guide the edge portion 103 of the cloth 100 toward the upper transfer roller 17.

  When the operator places the cloth at the start of the bonding operation, the worker switches the posture of the first guide mechanism 70 to the second posture (see FIG. 8). The first guide mechanism 70 in the second posture does not interfere with the work. Therefore, the worker can easily work when arranging the cloth.

  In addition, this invention is not limited to the above-mentioned embodiment, A various change is possible. The first cover portion 861 only needs to cover a part of the right side surface 513 of the nozzle 51. The length of the second cover 862 in the extending direction may be the same as the length of the nozzle 51 in the extending direction. The shape of the first cover portion 861 and the second cover portion 862 is not limited to a plate shape, and may be a rod shape. The first cover portion 861 and the second cover portion 862 may include a roller or a belt. The roller or the belt may sandwich the cloth 100 between the nozzle 51, and the cloth 100 may be transported downstream in the transport direction by rotating the roller or the belt.

  The cloth bonding apparatus 1 may not include the second guide mechanism 60. The operator may abut the edge 101 of the cloth 100 against the right side surface of the nozzle support portion 43. The extending portion 65 may be provided on the nozzle support portion 43. The shape of the extending portion 65 is not limited to a rod shape, and may be a plate shape extending in parallel with the pedestal portion 2. The extending portion 65 may include a roller or a belt. The roller or the belt may sandwich the cloth 100 between the nozzle 51, and the cloth 100 may be transported downstream in the transport direction by rotating the roller or the belt.

  The cloth bonding apparatus 1 may include a belt instead of the upper transfer roller 17. The belt may convey the cloth 100 by pressing the cloth with the cloth 100 sandwiched between the belt 20 and rotating with the belt 20.

  The nozzle 51 does not include the upper surface 511, the lower surface 512, and the right side surface 513, and may be, for example, a substantially cylindrical shape. In this case, the cover 86 is opposite to the side where the first cover 861 covers the right end side of the substantially cylindrical nozzle and the second cover 862 is provided with the discharge port in the extending direction of the substantially cylindrical nozzle. Cover the side.

  The contact part 64 was fixed to the nozzle support part 43 via the first support part 61 and the second support part 62. The contact portion 64 may be fixed to the nozzle 51 (upper surface 511). The second support portion 62 that supports the contact portion 64 is connected to the first support portion 61 fixed to the nozzle support portion 43 by a screw 612. The second support part 62 may be directly fixed to the nozzle support part 43. The first support part 61 may support the contact part 64.

  The first guide mechanism 70 rotates the rotating portion 77 around the stepped screw 72, and switches the posture of the first guide mechanism 70 between the first posture and the second posture. The first guide mechanism 70 may switch the first posture and the second posture by another method. For example, the first guide mechanism 70 may be capable of moving the guide portion 83 left and right. The first guide mechanism 70 may switch the posture to the first posture by moving the guide portion 83 to the left side and bringing the guide portion 83 closer to the nozzle 51 from the left side. The first guide mechanism 70 may switch the posture to the second posture by moving the guide portion 83 to the right and moving the guide portion 83 away from the nozzle 51.

  The upper transfer roller 17 and the lower transfer unit 90 function as the “transfer mechanism” of the present invention. The screw 72 functions as the “switching mechanism” of the present invention.
