[0012]
Next, the holder 10 will be further described with reference to FIG. The embroidery frame 11 has a pair of frames that can be separated from each other, for example, an inner frame 41 and an outer frame so that the embroidery object can be held in a state where the embroidery planned place in the embroidery object is tightly stretched in the embroidery space 12. It consists of 42 and. In this case, the space inside the inner frame 41 is the embroidery space 12. The connecting members 13 and 14 are formed in a thin plate shape so that they can be slid under the pressing spring 33 by being pushed along the receiving surfaces 21a and 22a of the holding members 21 and 22 in the holders 8 and 9. It has become. As an example of means for forming such a plate shape, for example, a metal plate is bent into a crank shape in cross section, and one piece thereof is used as a connecting plate. The bent one piece 43 on the opposite side is fixed to the inner frame 41 as a fixing piece for the embroidery frame 11, for example. The connecting members 13 and 14 may be attached to the outer frame 42. Reference numeral 44 denotes a guide groove provided on the end 14a on the back side of the connecting member 14 for guiding the position of the connecting member 14 in the left-right direction with respect to the holder 9 when the embroidery frame 11 is attached to the holders 8 and 9. is there. The guide groove 44 is formed in a shape that gradually becomes narrower from the back end 44a toward the deep part of the guide groove 44 in order to enable smooth guidance. 45 and 46 are fitting portions provided on the connecting members 13 and 14 of the pair of fitting portions, and are formed with fitting recesses correspondingly formed so that the fitting protrusions 31 and 31 can be fitted. Show. These fitting recesses 45 and 46 are illustrated as through holes, but may be bottomed recesses that open to the lower surfaces of the connecting members 13 and 14. These fitting recesses 45 and 46 are located at positions corresponding to the fitting projections 31 and 31, that is, when the connecting members 13 and 14 are brought into a predetermined position with respect to the holding members 21 and 22, respectively. It is provided at the position where it overlaps. These fitting recesses 45 and 46 are connected to each other by the weight of the embroidery object 15 attached to the holder 10 so that the fitting state with the fitting projections 31 and 31 can be maintained firmly. 13 and 14 are provided on the front end portions 13b and 14b on the side where the load applied to the receiving surfaces 21a and 22a greatly increases. The fitting concave portion 45 causes a large shrinkage force on the embroidery object due to an increase in the number of embroidery needles on the embroidery object, and the shrinkage force causes a reduction in the width dimension of the inner frame 41. In order to prevent biting with the fitting convex part 31, it is formed in a long hole in the left-right direction. The relationship between the convex portion and the concave portion is relative to the positioning of the pair of fitting portions (31, 45, 46) and the function of transmitting the force in the horizontal direction, and the fitting portions 31, 31 are fitted. On the other hand, the fitting portions 45 and 46 may be formed in the corresponding fitting convex portions while being formed in the mating concave portions. Also, the installation position may be the front side of the presser spring 33 (FIG. 2), but it may be in the middle of the presser portions 36, 38 on the lower side of the presser spring 33. Further, the pair of guide members composed of the guide piece 30 and the guide groove 44 are relative, the connecting member 14 side may be tapered, and the holder 9 side may be formed in a corresponding funnel-shaped recess.
[0013]
A case where the embroidery object 15 is embroidered using the embroidery frame 11 will be described. When embroidery is performed on the embroidery object 15, the embroidery object 15 is mounted on the embroidery frame 11 so that the planned embroidery position of the embroidery object 15 is located in the embroidery space 12. Next, the embroidery frame 11 is loaded into the holders 8 and 9. The operation advances the embroidery frame 11 into the space between the left and right holders 8 and 9 toward the back, and the left and right connecting members 13 and 14 move the receiving surfaces 21a and 22a of the holding members 21 and 22 in the holders 8 and 9, respectively. Insert under the spring 33 along 22a. In this case, the insertion of the connecting member 14 will be described as an example with reference to FIG. The connecting member 13 is inserted in parallel with the connecting member 14. First, as shown in (A), the end portion 14a is advanced in the direction of the arrow 47 and is slid under the presser portion 36 along the receiving surface 22a. The reason why the arrow 47 is inclined is to avoid interference between the connecting member 14 and the fitting convex portion 31. However, since the fitting convex portion 31 is formed with a low height as described above, the inclination may be extremely small enough to clear the fitting convex portion 31, and is inserted in a state substantially along the receiving surface 22a. Can be done. Next, as shown by arrow 48 in (B), the end portion 14a is directed to the gap 27. In this case, since the end portion 14a is pressed downward by the pressing portion 38, the end portion 14a can be directed to the gap 27 without causing the end portion 14a to abut against the levitation prevention body 26. In this case, the guide member 30 is advanced so as to enter the guide groove 44, so that the connecting member 14 is guided to the holder 9 in an appropriate position in the left-right direction. As a result, the fitting recess 46 smoothly moves to a position where it overlaps with the fitting projection 31. In addition, when the right and left positions of the connecting member 14 are appropriate, the left and right positions of the connecting member 13 with respect to the holder 8 are also interlocked with each other. When the connecting member 14 is advanced as described above and the tip of the connecting member 14 comes into contact with the stopper 28, the fitting recess 46 is overlapped with the fitting protrusion 31. If it becomes so, as shown to (C), the edge part 14b of the connection member 14 will be lowered | hung on the receiving surface 22a, and the fitting recessed part 46 will be fitted with the fitting convex part 31. FIG. With the above operation, the embroidery frame 11 is attached to the holders 8 and 9 at a predetermined position.
[0014]
Next, the operation at the time of embroidery on the embroidery object loaded in the embroidery sewing machine 1 as described above will be described. The drive frame 7 moves in the directions of arrows 7a and 7b based on a predetermined program. The movement is transmitted to the embroidery frame 11 through the holding members 21 and 22, the fitting convex portions 31 and 31, the fitting concave portions 45 and 46, and the connecting members 13 and 14, and the embroidery object 15 moves integrally with the drive frame 7. . In synchronism with the movement, the needle bar 5 moves up and down, and the embroidery 15 is embroidered by the needle 6. In the above case, since the holding portion 36 of the pressing spring 33 prevents the coupling members 13 and 14 from being lifted, the fitting state between the fitting concave portions 45 and 46 and the fitting convex portions 31 and 31 is maintained extremely firmly. . Therefore, the accuracy of movement of the embroidery object 15 is stably maintained, and the embroidery object 15 is stably embroidered with a predetermined pattern stably. The fitting state between the fitting concave portions 45 and 46 and the fitting convex portions 31 and 31 is also maintained by a load applied to the connecting members 13 and 14 due to the weight of the holder 10 and the weight of the embroidery object 15.
[0015]
Removal of the embroidery frame 11 after completion of embroidery is performed in the reverse procedure to the above. That is, first, the end portion 14b is lifted from the state of FIG. 4C, and the fitting recess 46 and the fitting projection 31 are disengaged. Similarly, with respect to the connecting member 13, the fitting concave portion 45 and the fitting convex portion 31 are disengaged. Next, when the embroidery frame 11 is pulled forward, the connecting members 13 and 14 come out from between the holding members 21 and 22 and the pressing spring 33, and the embroidery frame 11 is detached from the holders 8 and 9.
[0016]
Next, in the case of the above embroidery, when the embroidery object 15 is a garment such as a trainer and embroidery is performed on the chest or back thereof, the fitting recesses 45, 46 and the fitting protrusions 31, The certainty of maintaining a fitting state with 31 increases. That is, when embroidery is performed in the above place, the embroidery frame 11 is positioned with respect to the embroidery object 15 in the relationship shown in FIG. The center of gravity of the embroidery frame 11 is substantially at the center position of the embroidery frame 11 as indicated by symbol G when the embroidery object is not attached. However, when the embroidery object 15 as described above is mounted, the position of the center of gravity in the mounted state becomes a front side position as compared with the case where the embroidery object 15 is not mounted as indicated by the symbol G ′ due to the weight of the sleeve 15a. For this reason, the load applied from the connecting members 13 and 14 to the receiving surfaces 21a and 22a greatly increases on the end portions 13b and 14b side. Due to the increased load, the end portions 13b and 14b are more difficult to lift from the receiving surfaces 21a and 22a, and the fitting state between the fitting convex portions 31 and 31 and the fitting concave portions 45 and 46 is firmly maintained.
[0017]
Next, the example of FIG. 6 is intended to prevent erroneous damage to the push spring when the embroidery frame is attached to the holder. In the figure, reference numeral 50 denotes a deformation limiting member for preventing excessive deformation of the pressing spring 33e, which is formed of a hard material and is fixedly provided at a position as shown. The deformation limiting member 50 limits the deformation of the portion near the base 34e of the pressing spring 33e by the connecting member when the embroidery frame is attached within the range of its elastic limit. As a result, it is possible to prevent an accident that the pressing spring 33e is permanently deformed and the connecting member cannot be pressed. In addition, the part which is considered functionally the same or equivalent to the thing of the previous figure, and overlaps description is attached | subjected to the code | symbol same as the previous figure, and the overlapping description is abbreviate | omitted.
[0018]
【The invention's effect】
As described above, in the present invention, when the embroidery frame 11 is attached to the holding members 21 and 22, the connecting members 13 and 14 are pushed from the front side along the receiving surfaces 21a and 22a of the holding members 21 and 22. The effect that it can be attached by a simple operation by simply inserting it under the spring 33 and dropping the connecting members 13 and 14 onto the receiving surfaces 21a and 22a of the holding members 21 and 22 when the fitting portions 31, 45 and 46 overlap. There is.
In addition, when embroidery is performed in the above-mentioned attachment state, the movement of the drive frame 7 is transmitted to the embroidery frame 11 through the holding members 21 and 22, the fitting portions 31, 45 and 46, and the connecting members 13 and 14. In addition, in this case, the push spring 33 prevents the coupling members 13 and 14 from being lifted and maintains the fitted state of the fitting portion, so that the movement transmission from the drive frame 7 to the embroidery frame 11 can be ensured. Therefore, the embroidery frame 11 can always be moved accurately, and the cloth 15 previously attached to the embroidery frame 11 has an effect of accurately sewing the pattern.
Further, even if the fitting convex portion and the fitting concave portion, which are fitted to each other, are configured to transmit the accurate movement as described above, the pressing members 33 and 14 are pressed by the pressing springs 33 so that the above-described movement is transmitted. Since the fitting is maintained, the height of the fitting convex portions 31 and 31 is low enough to transmit the above movement. This means that the insertion operation at the time of attachment can be easily performed in a state in which the connecting members 13 and 14 are brought close to the receiving surfaces 21a and 22a of the holding members 21 and 22, that is, in a state where the connecting members 13 and 14 are close to the horizontal. There is also an effect that can be done.
In addition, as described with reference to FIG. 5, the weight of the front side of the sleeve 15 a or the like causes the center of gravity position G to rise even if it is a front side position as compared with the case where it is not attached as indicated by reference numeral G ′. Due to the presence of the blocking piece 26 , the rear end portions of the connecting members 13 , 14 do not lift from the receiving surface, and the effect of maintaining the integrity and preventing the embroidery from being disturbed.
Moreover, even if the floating preventing member 26 at a small gap 27 for end differential write from the receiving surface 21a is disposed, inserting the end portion 14 a of the connecting member 14 as also shown in FIG. 4 If, even heavy weight on the front side of such sleeve 15 a, the presence of the pressing portion 38 for guidance equip the rear side of the push spring 33, without the end portion 14 a is abutting the floating preventing member 26 There is an effect on work efficiency that proceeds toward the gap 27 and enables accurate mounting.
