Best Mode for Carrying Out the Invention
[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. The components of the embodiments described below can be combined as appropriate. Also, some components may not be used.
[0010] [Embodiment] <String Assembly> FIG. 1 is a diagram showing an example of a string assembly 1 according to the present embodiment. FIG. 2 is a diagram showing an example of a string receiving part 10 according to the present embodiment. The string assembly 1 has a string receiving part 10 and a string S that is looped around and knitted to the string receiving part 10. The string assembly 1 is assumed to be attached to an opening whose dimensions are adjusted by adjusting the tightening degree of the knitted string S, such as a cut portion extending forward from the top edge of a shoe, a cut portion formed in the collar of an upper garment, or a fitting portion of a corset.
[0011] In the present embodiment, it is assumed that the object to which the string assembly 1 is attached is a shoe and the string S is a shoelace. Also, FIG. 1 shows the string assembly 1 in a plan view in the direction of attachment to the shoe. In a plan view of the shoe, the direction of the foot width of the shoe is referred to as the left-right direction, and the direction orthogonal to the left-right direction is referred to as the front-back direction. Also, among the front-back direction, the direction from the heel to the toe of the shoe is referred to as the front, and the direction from the toe to the heel is referred to as the back. Also, among the left-right direction, the inner side with respect to the left and right sides of the shoe is appropriately referred to as the center side, and the left and right sides with respect to the center side are referred to as the outer side. Also, in the string assembly 1, the side that becomes the outer side of the shoe when attached to the shoe is referred to as the front side, and the side that becomes the inner side of the shoe is referred to as the back side.
[0012] In this embodiment, the string S is a flat string having a front surface SA and a back surface SB. For convenience, they are referred to as the front surface SA and the back surface SB, but in this embodiment, the front surface SA and the back surface SB are equivalent. Also, the string S is not limited to a flat string, and may be a round string or a rubber-like string. In this embodiment, the string S is so-called over-lapped knitted, but it is also applicable to under-lapped knitting, single knitting, and parallel knitting. In this embodiment, one string S is knitted to the string receiving part 10, but it can also be appropriately applied to a knitting method combining two or more strings S. In this embodiment, an over-lapped knitted one for the right-foot shoe is shown, but it can be replaced with an over-lapped knitted one for the left-foot shoe by reversing the left and right.
[0013] As shown in FIGS. 1 and 2, the string receiving part 10 has a plurality of pairs of string hanging parts 11A, 11B, a pair of base parts 12A, 12B, a plurality of pairs of protrusion parts 13A, 13B, a connecting part 14, and an opening part 15. In this embodiment, the string receiving part 10 is made of a single piece of fabric.
[0014] The string hanging part 11A is a part where the string S is hooked from the front surface side to the back surface side or from the back surface side to the front surface side, and is a concave part having a bottom on the center side of the string receiving part 10. In the string hanging part 11A, the string S extending from the left direction is hooked and folded back to the right direction. The string hanging part 11B is a part where the string S is hooked from the front surface side to the back surface side or from the back surface side to the front surface side, and is a concave part having a bottom on the center side of the string receiving part 10. In the string hanging part 11B, the string S extending from the right direction is hooked and folded back to the left direction. The string hanging part 11A and the string hanging part 11B are formed symmetrically with respect to the left and right. The string hanging parts 11A, 11B are formed in a U shape in this embodiment, but may be formed in a shape having a circular shape at the bottom and a cut extending to the outside. That is, the string hanging parts 11A, 11B are notches having the outside in the left-right direction open and having a bottom on the inside.
[0015] The base portion 12A is a portion that connects the plurality of string-hanging portions 11A arranged in the front-rear direction. The base portion 12A is located on the left side (center side) of the string-hanging portion 11A and extends in the front-rear direction. The base portion 12B is a portion that connects the plurality of string-hanging portions 11B arranged in the front-rear direction. The base portion 12B is located on the right side (center side) of the string-hanging portion 11B and extends in the front-rear direction. The base portion 12A and the base portion 12B are formed symmetrically left and right. The base portions 12A and 12B are formed in a parallel rail shape in the present embodiment, but may be formed in a tapered shape, or may be formed in a V-shaped or U-shaped with the front closed.
[0016] The protrusion 13A is a portion that restricts the movement of the string S in the front-rear direction at the hooked portion when the string S is hooked on the string-hanging portion 11A, and is a convex portion that protrudes outward from the base portion 12A at positions adjacent to the front side and the rear side of the string-hanging portion 11A. The protrusion 13B is a portion that restricts the movement of the string S in the front-rear direction at the hooked portion when the string S is hooked on the string-hanging portion 11B, and is a convex portion that protrudes outward from the base portion 12B at positions adjacent to the front side and the rear side of the string-hanging portion 11B.
[0017] The connecting portion 14 is a portion that connects the left and right base portions 12A and 12B. The connecting portion 14 connects and integrates the front-end portion on the front side of the base portion 12A and the front-end portion on the front side of the base portion 12B. Thereby, the string receiving part 10 of the present embodiment presents a U-shaped as a whole in a plan view. Note that the string receiving part 10 of the present invention does not necessarily require the connecting portion 14, and the right side part having the string-hanging portion 11A, the base portion 12A, and the protrusion 13A and the left side part having the string-hanging portion 11B, the base portion 12B, and the protrusion 13B may be separated.
[0018] The opening 15 is a space between the base portion 12A and the base portion 12B. The opening 15 is open at least at the upper end of the string receiving part 10. When the string S is knitted to the string receiving part 10, the dimension in the left-right direction is adjusted by adjusting the tightening degree of the knitted string S.
[0019] In the present embodiment, the right portion of the string receiver part 10 is formed in a comb shape with the right side open by a string hanging part 11A, a base part 12A, and a protrusion part 13A. Further, the left portion of the string receiver part 10 is formed in a comb shape with the left side open by a string hanging part 11B, a base part 12B, and a protrusion part 13B.
[0020] <Object to be sewn> FIG. 3 is a diagram showing an example of the object to be sewn 20 according to the present embodiment. FIG. 4 is a diagram showing a state in which the string assembly 1 according to the present embodiment is sewn to the object to be sewn 20.
[0021] In the present embodiment, the object to be sewn 20 is the front part of a shoe. The shoe includes, for example, a sole and an upper located above the sole. The upper includes a front part which is the upper body, a chute, and a string S. As shown in FIG. 3, the front part, that is, the object to be sewn 20 in the present embodiment, has two stitching edges 21 that are stitched when the front part is three-dimensionally assembled. The stitching edges 21 are located at the end edge on the heel side in the object to be sewn 20 of the present embodiment. Behind the object to be sewn 20, there are formed an opening 22 for inserting the wearer's foot and a throat part 23 that communicates with the opening 22 and extends forward from the opening 22.
[0022] As shown in FIG. 4, the string assembly 1 is attached to the object to be sewn 20 so as to cover the throat part 23. When attaching the string assembly 1 to the object to be sewn 20, the right end of the protrusion part 13A (see FIG. 1) of the string receiver part 10 is fixed to the right side of the throat part 23, and the left end of the protrusion part 13B (see FIG. 1) is fixed to the left side of the throat part 23. That is, the protrusion parts 13A and 13B are fixed so that the string S hooked on the string hanging parts 11A and 11B does not fall off from the string hanging parts 11A and 11B. Thereby, the string S is attached in a state of being knitted into the object to be sewn 20. At this time, the portion surrounded by the string hanging parts 11A and 11B, the protrusion parts 13A and 13B, and the object to be sewn 20 functions as a virtual string passing hole through which the string S passes.
[0023] In this embodiment, the protrusions 13A and 13B are directly sewn onto the object to be sewn 20. The string receiving part 10 forms a stitch T extending in the front-rear direction at the right end of the protrusions 13A arranged in the front-rear direction, and similarly forms a stitch T extending in the front-rear direction at the left end of the protrusions 13B arranged in the front-rear direction, thereby being sewn onto the object to be sewn 20.
[0024] <String knitting assisting device> FIG. 5 is a perspective view showing an example of the string knitting assisting device according to this embodiment. FIG. 6 is a perspective view showing an example of the support jig 30 according to this embodiment. The string knitting assisting device assists in creating the string assembly 1 as shown in FIG. 1.
[0025] As shown in FIG. 5, the string knitting assisting device includes a support jig 30 that supports the string receiving part 10 so that the front-rear direction thereof stands vertically, and string holding jigs 40A and 40B that hold both ends of the string S respectively. In the string knitting assisting device, the string S held at both ends by the string holding jigs 40A and 40B is looped around the string receiving part 10 supported by the support jig 30 to generate the string assembly 1.
[0026] In the following description, the local coordinate system defined for the support jig 30 is appropriately referred to as the jig coordinate system. The jig coordinate system is defined by an XYZ orthogonal coordinate system. In this embodiment, the positional relationship of each part is described based on the jig coordinate system. The direction parallel to the X-axis in a predetermined plane is defined as the X-axis direction. The direction parallel to the Y-axis in the predetermined plane orthogonal to the X-axis is defined as the Y-axis direction. The direction parallel to the Z-axis orthogonal to the predetermined plane is defined as the Z-axis direction. Also, in this embodiment, the plane including the X-axis and the Y-axis is appropriately referred to as the XY plane. The plane including the X-axis and the Z-axis is appropriately referred to as the XZ plane. The plane including the Y-axis and the Z-axis is appropriately referred to as the YZ plane. The XY plane is parallel to the predetermined plane. The XY plane, the XZ plane, and the YZ plane are orthogonal to each other. Also, in this embodiment, it is assumed that the XY plane is parallel to the horizontal plane. The Z-axis direction is the up-down direction. The +Z direction is the upward direction and the -Z direction is the downward direction. Note that the XY plane may be inclined with respect to the horizontal plane.
[0027] The support jig 30 is a jig for supporting the string receiving parts 10 so that the front-rear direction stands upright in the Z-axis direction. As shown in FIG. 6, the support jig 30 has a base 31 and a pair of support columns 32A and 32B standing upright from the base 31. The base 31 has a plate shape parallel to the XY plane. The support columns 32A and 32B extend in the Z-axis direction of the base 31 and are formed side by side in the X-axis direction. The distance between the support column 32A and the support column 32B may be provided so as to be changeable with respect to the base 31.
[0028] In the present embodiment, groove portions 33A and 33B that penetrate in the X-axis direction and extend in the Z-axis direction are respectively formed at the central portions in the Y-axis direction of the support columns 32A and 32B. In the support jig 30 of the present embodiment, by inserting the string receiving parts 10 along the groove portions 33A and 33B, the front-rear direction of the string receiving parts 10 is supported so as to stand upright in the Z-axis direction. In FIG. 5, the description of the support columns 32A and 32B on the front side of the paper surface with respect to the groove portions 33A and 33B is omitted.
[0029] The groove portions 33A and 33B support the front and back of the base portions 12A and 12B of the string receiving parts 10. In a state of being supported by the support columns 32A and 32B, a protrusion 13A protrudes on the side opposite to the support column 32B of the support column 32A, and a protrusion 13B protrudes on the side opposite to the support column 32A of the support column 32B. Thereby, the string hanging portions 11A and 11B and the protrusions 13A and 13B are supported in alignment in the vertical direction.
[0030] With the string receiving parts 10 supported by the support jig 30, by looping the string S around the string hanging portions 11A and 11B, the string S is woven around the string receiving parts 10 together with the two support columns 32A and 32B. After the string S is woven around the string receiving parts 10 to create the string assembly 1, by pulling out the string assembly 1 upward in the Z-axis direction from the two support columns 32A and 32B, the support of the string assembly 1 by the support jig 30 can be released.
[0031] The support jig 30 may have a rotating shaft member 34 for rotating the support jig 30 around the Y-axis. As will be described later, in the overlap knitting, there is a step of rotating the support jig 30 around the Y-axis, but it is preferable to have a rotation mechanism for rotating around each axis according to the knitting method to be performed. For example, in single knitting and parallel knitting, since there is a step of rotating the support jig 30 around the Z-axis, it is preferable to have a rotating shaft member for rotating the support jig 30 around the Z-axis.
[0032] As shown in FIG. 5, for example, the rotating shaft member 34 is fixed to the base 31. The rotating shaft member 34 may be connected to a rotation drive source and an operation device (not shown), and may be configured to rotate the support jig 30 around the Y-axis when the operation device is operated by an operator. The rotation direction depends on the crossing direction of the left and right strings S. Also, as will be described later, in the overlap knitting, the number of rotations around the Y-axis corresponding to the number of sets of string hanging portions 11A and 11B corresponding to the holes through which the string S passes is performed. Specifically, if the number of sets of the string hanging portions 11A and 11B is a, which is a positive integer of 2 or more, and the required number of rotations around the Y-axis is n, then n is represented by the number obtained by rounding up (a - 1) / 2 to an integer. In other words, n is an integer that satisfies a / 2 ≧ n ≧ (a - 1) / 2.
[0033] The string holding jigs 40A and 40B are jigs for holding the ends of the string S, respectively. The string holding jigs 40A and 40B are movable relative to the support jig 30 in the X-axis direction, Y-axis direction, and Z-axis direction. Also, the string holding jigs 40A and 40B can rotate the string S around the longitudinal direction of the held string S. In the present embodiment, the string holding jigs 40A and 40B each have a posture adjusting portion 41 and a pay-out amount adjusting portion 42.
[0034] The posture adjusting portion 41 has a cylindrical shape through which the string S is inserted and has a flat hole 43 through which the string S passes. The flat hole 43 allows the movement of the string S, which is a flat string, in the longitudinal direction and inhibits the rotation around the longitudinal direction. That is, the posture adjusting portion 41 can swing the string S at the holding position as the string S rotates around the longitudinal direction of the string holding jigs 40A and 40B, and can eliminate the twist of the string S.
[0035] The pay-out amount adjustment part 42 adjusts the length of the string S hung on the string receiving part 10 supported by the support jig 30 from the string receiving part 10 to the string holding jigs 40A and 40B. In other words, the pay-out amount adjustment part 42 adjusts the position for holding the string S.
[0036] In the present embodiment, the pay-out amount adjustment part 42 has a cylindrical shape provided adjacent to the end side of the string S with respect to the posture adjustment part 41, and includes a blower that forms an air flow from the central side to the end side of the string S inside the cylindrical shape. Due to this air flow, a force for sending out the string S from the central side to the end side is generated inside the pay-out amount adjustment part 42. Since the pay-out amount adjustment part 42 of the string holding jig 40A and the pay-out amount adjustment part 42 of the string holding jig 40B always pull the string S from both ends, the string S between the string receiving part 10 and the string holding jigs 40A and 40B can be maintained in a taut state. Further, in order to maintain the tension of the string S by the air flow, when the string S is wound around the string receiving part 10, it can be automatically paid out by a necessary length.
[0037] The string knitting assisting device may further include a moving mechanism (not shown) that relatively moves the support jig 30, the string holding jig 40A, and the string holding jig 40B. The moving mechanism may be, for example, a robot arm that holds the string holding jig 40A and the string holding jig 40B respectively.
[0038] <String Knitting Assisting Method> FIG. 7 is a flowchart showing the string knitting assisting method according to the present embodiment. FIGS. 8 to 13 are diagrams for explaining the string knitting assisting method according to the present embodiment.
[0039] As shown in FIG. 8, the operator inserts the string receiving parts 10 into the support parts 32A and 32B along the groove parts 33A and 33B of the support jig 30 from above in the Z-axis direction, and the support jig 30 supports the string receiving parts 10 so that the front-rear direction stands in the Z-axis direction (step SA1). At this time, as shown in FIG. 9, the protrusion parts 13A and 13B are arranged so as to protrude outside the support parts 32A and 32B in the Y-direction view.
[0040] As shown in FIGS. 10 to 11, the operator attaches string holding jigs 40A and 40B to both ends of the string S, respectively. Next, the operator operates the string holding jigs 40A and 40B to loop the string S around the string receiving parts 10 to create the string assembly 1 (step SA2). The operator moves the string holding jigs 40A and 40B back and forth in the Y direction outside the support part 32A, outside the support part 32B, or between the support part 32A and the support part 32B, and hooks the string S on the string hanging parts 11A and 11B of the string receiving parts 10 in order from the lower stage, thereby knitting the string S to the string receiving parts 10.
[0041] The movement paths of the string holding jigs 40A and 40B at this time are set corresponding to the knitting method of the string S. Corresponding to the knitting method of the string S, the support jig 30 is appropriately rotated around the Y-axis along which the rotation shaft member 34 extends, so that the vertical relationship at the intersection of the string S held by the string holding jig 40A and the string S held by the string holding jig 40B can be changed. Further, by rotating the string S held by the posture adjusting parts 41 of the string holding jigs 40A and 40B around the longitudinal direction, the twist of the string S can be eliminated.
[0042] As shown in FIG. 12, the operator pulls out the string assembly 1 created by hooking the string S up to the uppermost string hanging parts 11A and 11B upward in the Z-axis direction from the two support parts 32A and 32B, thereby releasing the support of the string assembly 1 by the support jig 30 (step SA3).
[0043] As shown in FIG. 13, the operator attaches the created string assembly 1 to a predetermined position of the sewing object 20 by sewing (step SA4).
[0044] When the object 20 to be sewn is the front part of a shoe, for example, after sewing decorative parts to the front part, sewing the sewing edge 21 of the heel (see FIG. 3), sewing the heel pad or the body color, adhering the heel sponge, and sewing the shoe sole, and before sewing the loop through which the string S is passed in the left - right direction and sewn to the shoe sole, the string assembly 1 may be sewn to the object 20 to be sewn. Also, after sewing the decorative parts and before sewing the sewing edge 21 of the heel, the string assembly 1 may be sewn to the object 20 to be sewn.
[0045] FIG. 14 is a flowchart showing an example of a method for creating the string assembly 1 according to the present embodiment. FIGS. 15 to 18 are diagrams for explaining the method for creating the string assembly 1 according to the present embodiment. In the following description, an overlapping stitch for a right - foot shoe will be described. Also, in the following description, the Y - axis direction will be appropriately referred to as the front and the back.
[0046] With the surface that becomes the surface when attached to the object 20 to be sewn facing the back side, the string receiving part 10 is supported by the support jig 30. The operator operates the string holding jigs 40A and 40B holding both ends of the string S, arranges the string holding jig 40A on the right side of the support jig 30 and the string holding jig 40B on the left side of the support jig 30, and lowers them behind the support jig 30. As shown in FIG. 15, the string S is hooked behind the two support columns 32A and 32B (step SB1). Next, the string holding jigs 40A and 40B are moved in the Y - axis direction to move both ends of the string S forward respectively, and the string S is hooked from the back to the front on the lowermost string - hanging parts 11A and 11B respectively (step SB2).
[0047] As shown in FIG. 16, next, the operator moves the string holding jigs 40A and 40B in the Z - axis direction so that the right - hand string S held by the string holding jig 40A is positioned below the left - hand string S held by the string holding jig 40B. Next, the string holding jig 40A is moved to the left and the string holding jig 40B is moved to the right in the X - axis direction to cross the string S in front of the support columns 32A and 32B (step SB3).
[0048] As shown in FIG. 17, next, the operator passes the crossing portion of the string S between the two support portions 32A and 32B, and the both ends thereof climb over the support portions 32A and 32B from the front to the back. Then, the string holders 40A and 40B are moved in the Z-axis direction and the Y-axis direction (step SB4).
[0049] Similar to step SB2, the operator moves the string holders 40A and 40B in the Y-axis direction to move both ends of the string S forward respectively, and hooks the string S from the back to the front on the lowermost string hanging portions 11A and 11B among the empty string hanging portions 11A and 11B (step SB5). Note that in step SB5, the left and right positions of the string holders 40A and 40B are reversed compared with those in step SB2.
[0050] When the string S is hooked up to the uppermost stage of the string hanging portions 11A and 11B (step SB6; Yes), the creation of the string assembly 1 is completed.
[0051] When the string S is not hooked up to the uppermost stage of the string hanging portions 11A and 11B (step SB6; No), the operator moves the string holder 40A to the left side and the string holder 40B to the right side in the X-axis direction so as to return the left and right positions of the string holders 40A and 40B (step SB7). Thereby, the string S crosses again on the front side of the support portions 32A and 32B. At this time, since the left string S held by the string holder 40A is located below the right string S held by the string holder 40B, it is opposite to the crossing direction of the string S in step SB3.
[0052] The operator rotates the support jig 30 clockwise once around the Y-axis along which the rotary shaft member 34 extends (step SB8). Thereby, the right string S held by the string holder 40B is located below the left string S held by the string holder 40A.
[0053] Next, the operator moves the string holding jigs 40A and 40B in the Z-axis direction and the Y-axis direction such that the crossing portion of the string S passes between the two support portions 32A and 32B and both end portions thereof straddle the support portions 32A and 32B from the front to the back (step SB9), in the same manner as in step SB4.
[0054] The operator moves the string holding jigs 40A and 40B in the Y-axis direction, in the same manner as in step SB2, to move both ends of the string S forward, respectively, and hooks the string S on the lowermost string hanging portions 11A and 11B of the empty string hanging portions 11A and 11B from the back to the front (step SB10).
[0055] When the string S is hooked up to the uppermost stage of the string hanging portions 11A and 11B (step SB11; Yes), the creation of the string assembly 1 is completed. When the string S is not hooked up to the uppermost stage of the string hanging portions 11A and 11B (step SB11; No), the process returns to step SB3.
[0056] [First Modification Example] FIG. 19 is an exploded view showing an example of a string receiving part 10 and hole closing parts 16A and 16B according to the first modification example.
