Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a holding clip for holding a long work cloth in an embroidery frame.

[0002]

[Prior art]

 Conventionally, various embroidery machines have been put into practical use, such as a single-head embroidery machine having only one sewing machine arm section and a multi-head embroidery machine having a plurality of sewing machine arm sections. For example, in Japanese Patent Laid-Open No. 2-216253, a plurality of sewing machine arm portions are provided, and the same embroidery pattern can be simultaneously formed on a number of planar work cloths corresponding to the number of these sewing machine arm portions. A rectangular movable frame for mounting a plurality of flat frames holding these work cloths is mounted on the work table, and this movable frame is driven by an X-axis drive motor via an X-axis drive mechanism. A multi-head embroidery machine is proposed which is configured to be driven in the X-axis direction and to be driven in the Y-axis direction by a Y-axis drive motor through a Y-axis drive mechanism.

By the way, in this type of embroidery machine, it is also possible to embroider a similar work pattern on a long work cloth such as a piece of cloth at a plurality of locations. In this case, a rectangular original fabric frame is attached to the inner periphery of the movable frame, and a long work cloth is placed on one surface on a tunnel-shaped support member provided around the original fabric frame. Then, a clip having a predetermined length is elastically engaged with the support member from the upper side through the processing cloth, and the outer peripheral portion of the embroidery range of the work cloth is clamped by the plurality of clips on the original frame. It has become. Here, in the case of a simple type clip, the clip is generally C-shaped in cross section, and a grip portion having a predetermined width is spotted on the side surface of the clip so as to be easily detached from the support member. It is attached integrally by welding.

[0004]

[Problems to be solved by the device]

 By the way, generally, as the work cloth is sewn with an embroidery pattern, the work cloth shrinks, and due to the work cloth shrinkage, a large tension acts on the clip. Here, as described above, since the grip part with a predetermined width is attached to the side surface of the conventional clip by welding, the plate part of the clip part where this grip part is welded becomes thicker, and therefore the elasticity is increased. The power decreases. As a result, the tension received from the work cloth becomes larger than the elastic force of the clip, and the cloth side of the clip rises, or in the worst case, the clip comes off the support member. Further, there is a problem that a separate member for the handle portion is required and the number of processing steps for welding the handle portion to the clip increases.

The present invention has been made to solve the above problems, and an object thereof is to provide a work cloth holding clip provided with a handle portion without reducing the original elastic force of the clip. is there.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the work cloth holding clip according to claim 1 is engaged with a support member provided on an inner peripheral portion of a rectangular embroidery frame over substantially the entire inner periphery thereof. A clip main body made of an elastic material and having a predetermined length, and a grip portion for removing the clip main body from the support member. A grip portion formed by cutting and raising a part of the clip body.

[0007]

[Action]

 In the clip for sandwiching work cloth according to claim 1 having the above structure, a clip main body made of an elastic material and having a predetermined length is provided on an inner peripheral portion of a rectangular embroidery frame over substantially the entire inner periphery thereof. The clip body cooperates with the support member to elastically clamp the work cloth. By the way, the grip for removing the clip body from the support member is formed by cutting and raising a part of the clip body.Therefore, cutting and raising should reduce the elastic force of the clip body. Therefore, the work cloth can be strongly clamped in cooperation with the support member by the inherent large elastic force of the clip body. That is, even if the work cloth contracts during embroidery sewing, the clip does not come off from the support member. Further, the main clip body portion can be easily removed from the support member via the handle portion.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The present embodiment is a case where the present invention is applied to a holding clip for holding a long work cloth in a movable frame provided in a multi-head embroidery machine. First, a description will be given of the multi-head embroidery machine M, as shown in FIG. 1, on the rear side of the upper surface of the base frame 1 extending in the left-right direction, a sewing machine supporting a rectangular shape in plan view having a predetermined length in the left-right direction is supported. A board 2 is provided, and three embroidery machines MH are arranged on the sewing machine support board 2 in a row in the left-right direction at predetermined intervals. At the front end of the arm portion 3 of the embroidery sewing machine MH, needle bar cases 7 having 12 needle bars (not shown) arranged in a row in the left-right direction are mounted, and needle bars not shown in the figure are attached. The needle bar case 7 can be moved in the left-right direction by the bar switching mechanism, and the needle bar for forming embroidery stitches with the embroidery thread of a desired color can be selectively selected.

On the other hand, as shown in FIG. 1, the bed main body 5 at the lower end of the pedestal 4 connected to the arm 3 is mounted on the sewing machine support plate 2, and the cylinder bed is inserted from the front end of the bed main body 5. 6 extends forward, and a thread catcher (not shown) is provided at the front end of the cylinder bed 6, and the embroidery thread of a desired color can be formed by cooperation with the sewing needle 8 attached to the selected needle bar. Embroidery stitches are formed on the work cloth W. Here, an upper shaft (not shown) for moving the needle bar and the balance 9 up and down and a lower shaft (not shown) for rotating the thread catcher are provided by a V belt 10 connected to a sewing machine motor (not shown). It is driven by a drive shaft 11 that is rotationally driven.

Further, as shown in FIG. 1, a work table 13 is disposed on the front side of the sewing machine support plate 2 so as to be substantially level with the upper surface of the cylinder bed 6, and the work table 13 is provided. A movable frame 16 having a rectangular shape in a plan view extending in the left-right direction is placed on a pair of auxiliary tables 14 and 15 including the work table 13 provided on both left and right sides of the work table 13. The drive frame portion 16a at the right end of the movable frame 16 is driven to move in the X-axis direction (left-right direction) by an X-axis drive mechanism (not shown), and the drive frame portion 16b at the left end thereof and the drive frame portion 16b. The portion 16a and the portion 16a are simultaneously moved and driven in the Y-axis direction (front-back direction) by a Y-axis drive mechanism (not shown). Therefore, the movable frame 16 can be moved on the XY plane by the X-axis drive mechanism and the Y-axis drive mechanism.

Next, the original frame 20 for holding the long work cloth W between the movable frames 16 will be described with reference to FIGS. 2 to 4. At the inner peripheral portion of the movable frame 16, a mounting portion 16a lower than the movable frame 16 is formed integrally with the movable frame 16 over the entire length of the inner peripheral portion of the movable frame 16. The mounting portion 16a has a rectangular shape. As shown in FIG. 2, a raw fabric frame 20 having a substantially crank-shaped cross section is attached to its outer peripheral portion by a plurality of screws 21. A support member 22 having a substantially tunnel-shaped cross section is integrally formed on the original frame 20 over the substantially entire length thereof, as shown in FIGS.

Next, the work cloth holding clip 23 that engages with the support member 22 will be described. As shown in FIG. 2, the clip 23 includes a clip body portion 23a made of an elastic material and having a predetermined length and having a substantially horizontal C-shaped cross section, and as shown in FIGS. 3 and 4, the clip body 23a. The handle 23b is formed by bending and bending a part of one side surface from the upper surface of the central portion in the length direction of the portion 23a.

Next, the operation of attaching the long work cloth W to the support member 22, that is, the original frame 20 with the clip 23 will be described. As shown in FIG. 2, the work cloth W is first placed on the upper side of the original frame 20, and the supporting member 22 is provided on the inner peripheral portion of the movable frame 16, that is, over the substantially entire length of the original frame 20. The upper portion of the work cloth W is elastically pinched by the plurality of clips 23 in cooperation with the support member 22 by the plurality of clips 23. By the way, since the grip portion 23b for removing the clip 23 from the support member 22 is formed by cutting and raising a part of the clip main body portion 23a, the elastic force that the clip main body portion 23a has is cut off. Without lowering, the work cloth W can be strongly clamped in cooperation with the support member 22 by the original large elastic force of the clip body 23a. This prevents the clip 23 from coming off the support member 22 even if the work cloth W contracts during embroidery sewing. On the other hand, when the clip 23 is detached from the support member 22, the handle portion 23b is integrally formed with the clip body portion 23a. Therefore, if the handle portion 23b is lifted upward by hand, the clip body is pushed through the handle portion 23b. The part 23a can be easily removed from the support member 22. Here, since the handle portion 23b is formed by cutting and raising a part of the clip body portion 23a, a member for the handle portion 23b and a welding process are not required, and the clip 23 is easily manufactured. .

The grip portion 23b formed by cutting and raising a part of the clip main body portion 23a may have various kinds of shapes, and is not limited to the central portion, and may be two or more in any portion. It is also possible to configure. Needless to say, the present invention can be applied to work cloth holding clips having various shapes other than the horizontal C-shape in cross section.
