Description

Embroidery materials guidance device for embroidery sewing machine {EMBROIDERING MATERIAL GUIDING DEVICE FOR EMBROIDERING SEWING MACHINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an embroidery material guide device for supplying an embroidery material while being zigzag with respect to a place where a needle is present, in a sewing machine head of an embroidery sewing machine capable of sewing a string-like embroidery material such as a tape or a cord.

Background Art Conventionally, embroidery sewing machines with a so-called zigzag sewing machine capable of supplying a string-like embroidery material such as a tape or a cord while being zigzagly supplied to a place where a needle is present and sewed on a cloth (sewn material) are known. The configuration of a sewing head in a conventionally known zigzag-embroidered sewing machine will be described briefly. The sewing head has a needle bar at its lower end and is driven up and down, and a predetermined operation is made for the vertical drive of the needle bar. It is assembled so that the cloth press body which presses the to-be-enveloped object up and down at the timing, the concentric body with the needle bar, and the rotation body which is free to rotate around the shaft center, and the lever pin with respect to this rotation body are attached to the rotation body. It is provided with the guide lever (guide part) which guides an embroidery material to the position of the needle of a needle.

In the embroidery sewing machine provided with such a sewing head, the guide lever is calculated while calculating the sewing progress direction for the fabric based on the predetermined needle data, while controlling the rotating body so that the lever pin is always located in the front of the sewing progress direction. The embroidery material is supplied in a predetermined pattern by reciprocating around the lever pin in a predetermined pattern, and the needle bar is driven up and down to sew the embroidery material onto the fabric by stitching. As an example of such embroidery sewing machine, there is an apparatus described in Patent Document 1 shown below. Embroidery sewing machine described in Patent Literature 1 described above is a pair of the sewing machine head capable of zigzag stitching and other sewing heads capable of multicolor embroidery in pairs, and enables embroidery of combination embroidery by both sewing heads. It's a sewing machine.

The guide lever (guide part) of the sewing machine head which can be zigzag-sewn described in patent document 1 is a base member fixed to the rotating body by the lever pin, the guide member by which the guide was fixed to the tip, the base member, and the guide. It consists of a connection member which connects a member. A guide pin is fixed to the base member, and a connecting member is provided on the guide pin so as to be rotatable about its axis. A long hole is formed in the lower part of the connecting member, and the long hole is fitted with a mounting screw for fixing the guide member and a protruding pin formed in the guide member, and the guide member is positioned along the long hole with respect to the connecting member. This is possible.

By the way, the above-mentioned guide lever is a "sewing position" capable of zigzag stitching to guide the embroidery material where the needle of the needle is located, and the connecting member is rotated upward to the left center around the axis of the guide pin, and in particular, the lower end of the lever is evacuated upward. Switching to the "retracted position" to be made is possible by the manual operation of an operator. Thereby, for example, when a movable head is changed between a zigzag stitching head which performs a zigzag stitching operation and a general embroidery head which performs a normal stitching operation (not a zigzag stitching operation), or when the embroidery to the cloth is completed and the cloth is replaced. The guide lever can be temporarily retracted from the "sewing position" to the "retraction position".

Moreover, at the time of stitching, the height at the time of releasing the string-shaped embroidery material with respect to the to-be-sealed material, and what is called a "guide height" position can be changed. At this time, by loosening the mounting screw holding the guide member, moving the mounting position of the guide member up and down along the long hole with respect to the connecting member, and then tightening the loosened mounting screw again, eventually, the mounting position of the guide member. By changing only the length of the guide lever (guide part) and changing the position of the lower end of the guide lever, the position of the "height of the guide" can be adjusted.

In addition, a sewing machine head capable of zigzag stitching described in Patent Document 1 is provided with a motor (drive source) for vertically moving the fabric pressing body, and the cloth pressing body is driven up and down at the time of sewing by driving the motor. When the sewing machine stops, it is possible to retract upwards larger than the stroke at sewing. In addition, the bottom dead center in the up and down motion of the cloth pressing body at the time of sewing can be set, and the bottom dead center of the cloth pressing body can be changed according to the cloth thickness of a to-be-sealed object, the kind of string-like embroidery material, etc. It is supposed to be.

Patent Document 1: Japanese Patent Application Laid-Open No. 2008-302070

In the embroidery machine provided with a sewing machine head capable of conventional zigzag stitching as described in the Patent Document 1, a string-shaped embroidery material is applied to the to-be-sealed object depending on the cloth thickness of the object to be stitched and the type of the string-shaped embroidery material to be zigzag stitched. When changing the "height of the guide" position (height position of the guide lever) which is loosened, the operator must manually adjust the mounting position of the guide member as described above. However, it is laborious for the worker to perform such a work, and in particular, the embroidery sewing machine having a plurality of sewing heads capable of zigzag stitching is very time-consuming because it requires manual position adjustment for each sewing head. And since it is a manual adjustment by an operator himself, accurate positioning is difficult.

Moreover, in the embroidery machine provided with the sewing head which can be zigzag-sewn, embroidery materials may be laminated | stacked and sewn. In this case, it is possible to stably stitch the embroidery material by sequentially changing the position of the "guide height" which releases the embroidery material to the sewing object for each layer to be sewn. Each time the sewing is finished, the sewing machine is stopped once, and the operator must manually adjust the position of the "height of the guide", and the working efficiency of embroidery sewing by the sewing machine will be significantly reduced. In addition, since the guide lever reciprocates around the lever pin in the related art, the width of the zigzag shake of the embroidery material changes when the "guide height" position is changed. For example, when stacking and sewing an embroidery material, if the position of the "guide height" is changed to a large upward position according to the state of overlap of the embroidery material, the width of the zigzag sway becomes relatively smaller than before the change, so that the embroidery material can be sewed. It may become impossible to carry out. Therefore, in view of such a situation, it is a fact that it has not been conventionally performed to change the position of "guide height" every time for each layer to be sewn when laminating and sewing an embroidery material.

In addition, in the conventional sewing machine head capable of zigzag stitching, even when the guide lever is retracted to the retracted position, the operator performs manual operation, which is cumbersome and may damage the machine by forgetting to retract the operator. There is not good situation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described point, and in the embroidery sewing machine having a sewing head capable of zigzag stitching, the position of the "guide height" for releasing the string-shaped embroidery material to the sewing object can be easily changed. An object of the present invention is to provide an embroidery material guide device for embroidery sewing machines.

Moreover, it aims at providing the embroidery material guide apparatus for embroidery sewing machines which can also be easily retracted to the predetermined retraction position of a guide lever.

An embroidery material guide apparatus for embroidery sewing according to the present invention is an embroidery material guide apparatus for embroidery sewing machines capable of zigzag stitching of embroidery materials with respect to a sewing object, comprising: a guide member 29 for guiding the embroidery material toward a sewing position; Support members 25 to 28 for supporting the guide member 29 so as to reciprocate in the lateral direction, and a rocking member 21 coupled to the guide member 29 so as to allow relative up and down movement of the guide member 29. And height positions of the swinging mechanisms 36, 34, 35, 35a, 19, 18, 23, and the support members 25 to 28, which swing the swinging member 21 in conjunction with the up and down movement of the needle bar 2; Height position changing mechanisms 7, 8, 6, 4, and 9 for changing the height. In addition, the code | symbol shown in parentheses records the drawing reference number of the corresponding element in the Example mentioned later for simple reference.

According to this invention, the position of the "height of a guide" which releases the embroidery material from a guide member is changed by changing the height position of the support member which supports a guide member so that a reciprocating movement is possible by a height position change mechanism. Since the swinging member for reciprocating the guide member is coupled to the guide member to allow relative up and down movement of the guide member, when the guide member moves in the up or down direction with the change of the height position of the support member, The up-and-down movement of this guide member is not impeded. In this way, since the height position change mechanism changes the height position of the guide member together with the support member, the position of the "height of the guide" can be automatically changed by the height position change mechanism, and the manual operation by a conventional operator No work is required, which eliminates the effort. And even when the embroidery material is laminated and sewn, for example, if the height position of the guide member for each layer to be sewn is set only by an operation panel or the like, the position of the "height of the guide" is automatically adjusted according to the layer to be sewn. Is changed and sewing is performed, which indicates that it is not necessary to stop the sewing machine deliberately every time the layers are overlapped as in the prior art, and thus it is possible to work without lowering the working efficiency of embroidery stitching by the sewing machine.

In addition, the guide member supported in the transverse direction so as to be reciprocated in the lateral direction is coupled so as to be relatively up and down relative to the swinging member, so that the "height of the guide" position is changed by changing the height position of the supporting member. Even if the height position of the guide member) is changed, the width of the zigzag shake of the embroidery material does not change. This makes it possible to reliably sew the embroidery material regardless of the position of the "height of the guide". Furthermore, by changing the height position of the support member to a predetermined upper position corresponding to the retracted position, it is possible to automatically retract the guide member to the retracted position, thereby reducing the labor of the operator when retracting the guide member. In addition, the operator forgets to retract the guide member so that the sewing machine can be prevented from being damaged.

In a preferred embodiment of the present invention, the height position changing mechanism is a cloth pressing device for moving up and down the cloth pressing member for pressing the to-be-sealed material, and the supporting member is any one element that moves up and down within the cloth pressing device. Is bound to Thereby, the height position of a support member can be changed according to the up-down movement of the cloth pressing member by a cloth pressing lifting mechanism. That is, the cloth pressing device can change the bottom dead center of the driving range of the cloth pressing member at the time of sewing, and retract the cloth pressing member to a predetermined retracted position when the sewing machine stops. From this, it is possible to change the "height of the guide" position (finally the height of the guide member) with the change of the bottom dead center of the fabric pressing member, and to retract the guide member with the evacuation of the fabric pressing member to the retreat position. Since the work is automatically performed, the height position adjustment of the guide member is performed by using the existing cloth pressing device as the height position changing mechanism without providing a special mechanism for height position adjustment of the guide member and evacuation to the retraction position. And evacuation to the evacuation position.

As described above, according to the present invention, in the embroidery machine provided with a sewing head capable of zigzag stitching, the embroidery can be easily changed the position of the "height of the guide" where the string-like embroidery material is released from the sewing object. The embroidery material guide apparatus for sewing machines can be provided.

Moreover, the embroidery material guide apparatus for embroidery sewing machines which can be easily performed also with respect to the retraction to the predetermined retraction position of a guide lever can be provided.

Therefore, the cloth pressing body 10 moves up and down with the up and down movement of the support cylinder 4 and the cloth pressing support 9, and rotates around the axis of the needle bar 2 with the rotation of the rotary cylinder 11. It is supposed to. Such elements 7, 8, 6, 4 and 9 function as a "cloth pressing mechanism" for vertically moving the cloth pressing body 10 (cloth pressing member), and for moving up and down the guide member 29 which will be described later. It also functions as a "height position changing mechanism."

3 is a front view showing a part of the lower part of the sewing head H broken, and FIG. 4 is a three-dimensional view of the lower part of the sewing head H. FIG. As can be seen from this figure, the interlocking member 18 is fitted to the outer periphery of the rotary cylinder 11 so as to be movable up and down and rotatable. The connecting piece 19 is fixed to the interlocking member 18, and the connecting piece 19 is coupled to the engaging groove 11a formed on the outer circumference of the rotary cylinder 11. Thereby, the interlocking member 18 is integrally rotated with the rotating cylinder 11 with the rotation of the rotating cylinder 11. As shown in FIG. Moreover, the pivoting lever 21 (swinging member) is attached to the rotating cylinder 11 via the bracket 20. The swing lever 21 is freely mounted to the left and right sides of the needle bar 2 in the axial direction with respect to the rotary cylinder 11, with the lever pin 22 attached to the outer surface of the bracket 20 as a supporting point. . This rocking lever 21 is provided with one arm part 21a which extends laterally from the position of the lever pin 22, and the other arm part 21b which extends downward. A roller 23 is mounted at the tip of the arm portion 21a extending laterally, and the roller 23 is coupled to the linkage groove 19a of the connecting piece 19. On the other hand, the arm portion 21b extending downward of the swing lever 21 has a fork shape divided into two branches, and a roll 24 is provided at both lower ends thereof.

The cloth pressing body 10 is integrally formed with a supporting member 25 which forms a substantially rectangular plane (of course, the cloth pressing body 10 and the supporting member 25 may be separate bodies), and this supporting member 25 The guide rail 26 is fixed to the opposite side of the cloth pressing body (10). The slider 27 is provided in the guide rail 26 so that the slide movement is possible, and the guide member 29 is being fixed to the slider 27 via the bracket 28 formed in the U-shape. The bracket 28 extends the guide rail 26 and the slider 27 to the operation block 30 positioned between the rollers 24 and 24 of the arm portion 21b below the rocking lever 21. One of the supporting members 25 is fixed so as to be fitted as shown. The lower end of the guide member 29 is provided with a guide cylinder 29a for passing through the embroidery material T and feeding it to the position where the needle of the needle 3 is located. Moreover, the bobbin bracket 32 is fixed to the outer periphery of the rotating cylinder 11 via the bracket 20 and the arm member 31, and the bobbin 33 which wound the embroidery material T was rotated to the bobbin bracket 32 by rotation. Freely supported

In the position adjacent to the needle bar 2, as shown in FIG. 1, the guide shaft 34 arrange | positioned so that the axial direction may extend in an up-down direction is arrange | positioned. The lifting member 35 is attached to the guide shaft 34. The lifting member 35 is driven up and down along the axial direction while being guided to the guide shaft 34 by the transmission of the driving force by the rotation of the zigzag shaking motor 36 via the drive transmission mechanism (not shown). The elevating member 35 is provided with a fork portion 35a projecting substantially horizontally toward the needle bar 2, and the fork portion 35a is coupled to the groove portion 18a formed on the outer circumference of the interlocking member 18. have. Therefore, when the interlocking member 18 and the connecting piece 19 move up and down by the vertical movement of the elevating member 35, the up and down movement of the connecting piece 19 moves through the linking groove 19a and the roller 23 to the swing lever 21. Is converted to a swing. By swinging the swing lever 21, the bracket 28 fixed to the operation block 30 held by the swing lever 21 is positioned between the two rollers 24 of the lower arm portion 21b. ), The guide member 29 fixed to the slider 27 through the bracket 28 is left and right (laterally) with respect to the sewing progress direction in accordance with the movement of the slider 27 sliding along the guide rail 26. Direction). These elements 36, 34, 35, 35a, 19, 18, and 23 function as a swinging mechanism for swinging the swing lever 21 in conjunction with the up and down movement of the needle bar 2.

In FIG. 1, the lifting member 35 is in the upper limit position, the rocking lever 21 is rocked all the way to the left, and the guide member 29 is shown in the leftmost position. On the contrary, FIG. 5 shows a state where the elevating member 35 is at the lower limit position, the rocking lever 21 swings to the right to the end, and the guide member 29 is located at the rightmost side. FIG. 5 is a partial view of the lower part of the sewing head H in a state where the guide member 29 is located at the rightmost side. In order to understand and compare these figures, the guide member 29 is left and right in the support member 25 in synchronization with the reciprocation of the needle bar 2 between the left end position shown in FIG. 1 and the right end position shown in FIG. It is possible to slide back and forth. Thereby, the embroidery material T which passed through the guide cylinder 29a (refer FIG. 2) is zigzag left and right with respect to the sewing progress direction by a predetermined pattern, and the needle drop position (the position of the needle of the needle 3), That is, it is supplied to the stitching position), and is sewed to the to-be-sealed object one by one. In addition, in each said drawing, 37 is a well-known needle plate.

Here, in the sewing head H of the said structure, the operation of sewing the embroidery material T to the to-be-sealed thing (not shown) by stitching is demonstrated. First, the bobbin 33 wound on the embroidery material T is set to the bobbin bracket 32, and the embroidery material T is removed from the bobbin 33 and passed through the guide barrel 29a to drop the needle of the needle needle 3. To the location (where the needle is). In this state, the sewing object (not shown) is controlled to move in the XY direction based on the predetermined embroidery data, and the needle bar 2 is driven up and down so that the needle needle 3 and the kiln (not shown) are known. Stitch. At this time, since the guide member 29 is reciprocated left and right at a predetermined timing between the left end position shown in FIG. 1 and the right end position shown in FIG. 5 by driving the zigzag shake motor 36, the guide cylinder The embroidery material T guided to the needle drop position of the needle needle 3 by 29a moves to the left and right of the needle drop position for each round trip of the needle bar 2 (every stitch). Thereby, the embroidery material T is sewed into the to-be-sealed object one by one by zigzag stitching.

At this time, as the rotating cylinder 11 is rotated by the drive of the motor 13, the lever pin 22 is always controlled so as to be located in the front of the relative traveling direction of the sewing head H based on the movement of the workpiece. do. In addition, the cloth pressing body 10 is driven up and down at a predetermined timing with respect to the up and down driving of the needle bar 2 by the drive of the motor 7 to function as cloth pressing. At this time, the guide member 29 also moves up and down together with the fabric presser 10 according to the above-described configuration, but as can be seen from FIG. 3, the operation block 30 is moved up and down relative to the swing lever 21. Since the guide member 29 is held by the swing lever 21 so that the amount of reciprocating slide of the guide member 29 does not change even when its vertical position is changed (i.e., its relative positional relationship is automatically changed). There is no problem that the width of the zigzag fluctuation changes with respect to the stitching of the embroidery material T at the positioned position ("guide height" position) by being moved up and down. Then, the embroidery material T is finished to sew, and the guide member 29 is retracted from the stitched position shown in FIG. 6 to the retracted position shown in FIG. 7 by the driving of the motor 7 together with the cloth pressing body 10.

Next, the change of the height position of the guide member 29 is demonstrated. As described above, the guide member 29 moves up and down together with the cloth press body 10. For this reason, if the height of the bottom dead center of the cloth pressing body 10 is set, for example by a well-known operation panel according to the cloth thickness of a to-be-sealed material and the kind of string-like embroidery material as conventionally known, the cloth pressing body 10 As the height of the bottom dead center of) is changed, the height position of the guide member 29 is automatically changed accordingly.

Next, the case where the embroidery material T is laminated and sewn is demonstrated. The schematic diagram at the time of laminating | stacking and sewing this embroidery material T is shown in FIG. 8, (a) of FIG. 8 shows the sewing of the 1st layer, and FIG. 8 (b) shows the sewing of the 2nd layer. In addition, in the figure, the symbol S represents a to-be-sealed object.

When the embroidery material T is laminated and sewn, the height of the bottom dead center of the cloth pressing body 10 may be set to the operation panel for each step of sewing the layers. In the case of Fig. 8, the bottom dead center of the cloth pressing body 10 at the step of the first floor is set so that the distance from the upper surface of the needle plate 37 is L1, and is set to be L2 at the step of the second floor. Although omitted, the height of the bottom dead center of the cloth presser 10 is set to the distance from the upper surface of the needle plate 37 as needed, respectively. When the embroidery material T starts to sew, the guide member 29 changes as the height of the fabric pressing body 10 changes to L1 when the embroidery material T of the first layer is sewn according to the height of the bottom dead center set in the above-described setting. ), The height of the guide member 29 is automatically changed to L2 as the height of the cloth pressing body 10 is changed to L2 at the sewing of the second layer.

In this way, in the present invention, since the height position of the guide member 29 is automatically changed in accordance with the height setting of the cloth press body 10, the operator manually adjusts the position of the installation position of the guide member as in the prior art. The trouble to say is unnecessary and work efficiency does not fall. Moreover, since the guide member 29 is moved up and down with the drive of the cloth press body 10 by the motor 7 which moves the cloth press body 10 up and down, adjusting the height position of the guide member 29 It is not necessary to provide a special mechanism (dedicated height position changing mechanism) that only moves the guide member 29 up and down separately, so that the configuration is not complicated, and only by setting the bottom dead center of the cloth press body 10. Since the height of the guide member 29 can also be adjusted, it is simple and convenient.

In addition, when sewing of the embroidery material T is finished, the guide member 29 is also automatically retracted to the retracted position together with the fabric pressing body 10, so that the worker takes the effort to retract the guide member 29 as in the prior art. Not only is it possible to reduce the pressure, but it is also possible to prevent damage to the sewing machine resulting from the operator forgetting to retract the guide member 29.

In addition, in the above-mentioned embodiment, the guide cylinder 29a of the guide member 29 may be various shapes according to the embroidery material T to sew. In addition, although the guide member 29 is slidably supported by the guide rail 26 and the slider 27, it may be slidably supported in another form and reciprocally slides left and right with respect to the sewing progress direction.

In addition, it goes without saying that the up-and-down movement of the cloth pressing body 10 at the time of sewing is possible not to be performed by setting.

In addition, in the above-described embodiment, the operation block 30 is gripped so as to be inserted into the two rollers 24 of the arm portion 21b below the swing lever 21, and the operation block 30 is held. (Upwardly, the guide member 29 fixed to the slider 27 through the bracket 28 and the swing lever 21 are shown to be able to move up and down relatively, but not limited to this, but in another form. Any form may be used as long as the oscillation lever 21 grasps the operation block 30 (or the guide member 29) and slides with each other in accordance with the up and down movement of the support member 25. For example, a groove is formed in the side surface of the operation block 30, while a member for engaging or fitting with the formed groove is formed in the arm portion 21b below the swing lever 21, and such engagement or insertion is performed. By the fitting, the swing lever 21 may be configured to grip the operation block 30 so as to be slidably movable up and down. It goes without saying that the present invention is not limited to changing the relative positional relationship by sliding the slide.
