Description of the Related Art Hitherto, it has been known to embroider a one-point pattern, a stylized character or a logo mark for the purpose of imparting decorativeness to clothing and increasing its commercial value. In recent years, it has been automated by an automatic embroidery machine. Embroidery such as letters and one-point marks is mainly embroidered with precision, which is called flat embroidery, and embroidery threads are looped for embroidery in relatively large areas such as various emblems and logo marks. Embroidery made of pile fabric sewn in a shape is used, and various embroidery methods are known depending on applications. However, densely embroidered embroidery, which is generally called flat embroidery, lacks a three-dimensional effect.
The loops emerged from the fabric and gave a three-dimensional texture compared to flat embroidery, but the embroidery made of piled fabric had a short bristle foot, lacked a three-dimensional feel, and did not provide a soft texture.

The present invention is intended to solve such a problem, and a second object of the present invention is to provide an embroidery raising device capable of continuously and efficiently forming raised embroidery. Aim.

[0004]

According to a first aspect of the present invention, an embroidery thread is sewn on a cloth in a loop to form an embroidery portion made of a pile, and a tensile force is applied to the loop of the embroidery thread. An embroidery raising device for raising the embroidery thread of the embroidery portion by cutting the loop to give a plurality of flexible capturing needles which are bent in the shape of a letter inward and each of the capturing needles. A plurality of needles are arranged and implanted, and both ends are bent back to form a substantially C-shaped elastically deformable support base; a mounting seat for mounting and fixing the support base; A drive means for horizontally moving relative to the embroidery portion, a mounting shaft protruding from the mounting seat, a guide tube mounted on the drive means for guiding the mounting shaft to be vertically movable, and Hold the mounting shaft against A stopper ring, and a spring interposed between the guide cylinder and the mounting seat and between the guide cylinder and the stopper ring, and the driving means is provided in a state where the capture needle is in contact with the embroidery portion. The capture needle is moved horizontally, and the loop of the embroidery thread captured by the capture needle is pulled to cut the loop of the embroidery thread.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 denotes an embroidery unit, and 2 denotes an embroidery unit to be sewn on the fabric 1.
Is composed of a pile material 4 which is sewn in a loop and embroidery thread 3 emerges on one side of the fabric 1. In addition,
The embroidery unit 2 is automatically sewn on the fabric 1 by an automatic embroidery machine 10 serving as a driving means. The automatic embroidery machine 10 has a conventionally well-known structure including a gantry 11 for holding down the fabric 1 and an embroidery head 13 having a large number of needles 12 arranged above the gantry 11. By inputting a numerical value corresponding to the embroidery pattern to a control means (not shown) of the automatic embroidery machine 10 in advance, the gantry 11 for sewn the embroidery unit 2 on the fabric 1 is moved forward and backward in the front-rear direction. Moves in the left-right direction, and the embroidery thread 3 is sewn on one side of the cloth 1 in a loop to automatically form the embroidery section 2 composed of the pile 4. The embroidery portion 2 is raised by applying a tensile force to the loop 3A of the embroidery thread 3 constituting the embroidery portion 2 and cutting the loop.

Next, the structure of a raising device for raising the embroidery unit 2 will be described. The raising device includes a plurality of capture needles 15 having flexibility, an elastically deformable support base 16 on which the capture needles 15 are implanted, and a mounting seat 17 for fixing the support base 16.

The capture needle 15 is made of a metal wire having a small wire diameter, is formed in a V-shape by bending an intermediate portion thereof, and the base end side thereof is implanted in the support base 16. Capture needle 15
The support base 16 for implanting is made of a band-shaped leather having a relatively large thickness. The both ends of the support base 16 are bent in a curved shape to form a substantially C-shape as a whole and fixed to the back side of the mounting seat 17. doing. In addition, the support base 16 has four support bases 16.
Mounting seats 17 at 90 degree intervals so that
The capturing needles 15 are regularly implanted inward at a constant pitch on the respective support bases 16 of the support bases 16. Mounting base 17 for support base 16
Is a disk-shaped mounting plate 18, a mounting shaft 25 erected at the center of the mounting plate 18, and a guide cylinder 26 for vertically guiding the mounting shaft 25.
The guide tube 26 is screwed to a mounting stay 27 fixed to the embroidery head 13 of the automatic embroidery machine 10.
A stopper shaft 28 protrudes from the mounting shaft 25, while a notch groove into which the stopper shaft 28 fits is provided at an upper end edge of the guide cylinder 26.
30 are formed. Further, a stopper ring 31 is fixed to the mounting shaft 25 at a position above the stopper shaft 28 with a screw 32, and between the stopper ring 31 and the guide tube 26 and between the guide tube 26 and the mounting plate 18. Springs 35 and 36 are provided on the mounting shaft 25 so as to be interposed therebetween.

The operation of the embodiment constructed as described above will be described. First, the embroidery unit 2 is sewn to the cloth 1 by the automatic embroidery machine 10 in the same procedure as in the prior art. That is, a value corresponding to the embroidery pattern is input to the control means (not shown) of the automatic embroidery machine 10 in advance, and the gantry 11 for holding the fabric 1 is moved in the front-rear direction by the command from the control means, and the embroidery head 13 is moved. The embroidery thread 2 is sewn on one side of the fabric 1 in a loop by moving the fabric 1 in the left-right direction to form an embroidery portion 2 made of a pile fabric 4. At this time, the raised unit attached to the embroidery head 13 is held at the upper limit position as shown by a chain line in FIG. That is, the stopper shaft 28 protruding from the mounting shaft 25 rides on the upper end edge of the guide tube 26 for guiding the mounting shaft 25, and the mounting shaft 25 is moved by the spring 36 interposed between the guide tube 26 and the mounting plate 18. It is held in a state pressed against the lower side,
The capture needle 15 implanted in the support base 16 does not get caught on the embroidery part 2. Then, at the stage when the sewing process of the embroidery portion 2 is completed, the mounting shaft 25 is rotated to drop the stopper shaft 28 into the notch groove 30 formed in the guide cylinder 26, thereby forming the support base 16 on which the capture needle 15 is implanted. The mounting plate 18 is moved downward, and the capture needle 15 is lowered to a position where it comes into contact with the embroidery unit 2. When the support base 16 on which the capturing needle 15 is implanted is lowered,
A spring 35, in which the mounting plate 18 is interposed between the stopper ring 31 and the guide tube 26 and between the guide tube 26 and the mounting plate 18,
Supported elastically by 36. Further, the support base 16 fixed to the back surface side of the mounting plate 18 is formed by folding both ends into a curved shape and forming a C-shape so that the central portion of the support base 16 rises as shown in FIG. When the mounting plate 18 is lowered, the capture needle 15 implanted at the center of the support base 16 partially contacts the embroidery portion 2 and the capture needles implanted at both ends of the support base 16. The needle 15 is slightly separated from the tip of the embroidery unit 2. The height of the mounting plate 18 can be arbitrarily adjusted according to the height of the embroidery portion 2 protruding from the fabric 1 by loosening the screw 32 of the stopper ring 31 provided on the mounting shaft 25 and adjusting the position of the stopper ring 31. Can be changed. Thereafter, a numerical value corresponding to a pattern for raising is input to a control means (not shown) of the automatic embroidery machine 10, and
For example, the embroidery head 13 is slightly shifted laterally while the mount 11 of the automatic embroidery machine 10 is linearly reciprocated in the front-rear direction so that the capture needle 15 implanted in the embroidery section 16 is along the embroidery section 2. Move. In addition, the movement pattern of the gantry 11 and the embroidery head 13 can be changed by moving the embroidery head 13 slightly in the horizontal direction while linearly reciprocating the gantry 11 in the front-rear direction as described above by changing the numerical value input to the control means. In addition to moving the embroidery head 13 and the embroidery part 2, for example, the embroidery head 13 and the embroidery part 2 can be relatively obliquely moved or circularly moved. To move and attach the capture needle 15 along the entire surface of the embroidery part 2.
You only have to move 18 horizontally. Then, by moving the gantry 11 and the embroidery head 13 of the automatic embroidery machine 10 in a state where the capture needle 15 is in contact with the embroidery unit 2, the capture needle 15 is hooked on the loop 3 </ b> A of the embroidery unit 2. In this case, how the embroidery head 13 is moved with respect to the embroidery unit 2 by arranging the four support bases 16 on which the capture needles 15 are implanted in a cross shape on the back side of the mounting plate 18 so as to cross each other. Even if you do
At least one of the four support bases 16
The capturing needle 15 implanted in the embroidery 16 is securely hooked on the loop 3A of the embroidery unit 2. Further, by arranging the support bases 16 in a cross shape so as to cross each other, two sets of support bases 16 facing each other around the mounting plate 18 are linearly continuous, and each support base 16 is connected to each support base 16. Capture needle bent in the shape of a letter
For example, when the embroidery head 15 is advanced to the inside, for example, when the gantry 11 of the automatic embroidery machine 10 is linearly reciprocated back and forth, The trapping needle 15 located on the side is deformed so as to be bent further in a C-shape and passes through the embroidery portion 2, but the catching needle 15 located on the rear side is caught by the loop 3A and embroidered as shown in FIG. As the head 13 advances, the capture needle 15 bent in a U-shape is bent, and the loop 3A is securely entangled with the capture needle 15. Conversely, when the embroidery head 13 retreats with respect to the embroidery unit 2,
Since the capture needle 15 located on the rear side passes through the embroidery section 2 and the capture needle 15 located on the front side is hooked on the loop 3A, the embroidery section 2 can be repeatedly subjected to a tensile force by the back and forth movement of the gantry 11. . Then, by moving the gantry 11 in this way and pulling the loop 3A entangled with the capture needle 15, the loop 3A is pulled out and the embroidery thread 3 of the embroidery head 13 is extended. At this time, the support base for implanting the capture needle 15
16 is formed of a relatively thick leather capable of elastic deformation, and a mounting plate 18 for fixing the support base 16 is provided between the stopper ring 31 and the guide tube 26 and between the guide tube 26 and the mounting plate 18. When the gantry 11 is moved back and forth with the loop 3A hooked on the capture needle 15, as shown in FIG.
18 is relatively pulled, the support base 16 is deformed so as to be slightly flattened, and the mounting plate 18 descends against the bias of the spring 35 interposed between the stopper ring 31 and the mounting plate 18, The capture needle 15 does not immediately leave the loop 3A, but can continuously apply a pulling force. Further, it is assumed that an excessive force is applied to the capture needle 15 with the movement of the gantry 11, and the support base 16 and the spring Shock applied to the capture needle 15 can be absorbed by the pins 35 and 36, so that an appropriate contact pressure can be maintained, and the fabric 1 on which the embroidery portion 2 is sewn is not pulled following the back and forth movement of the gantry 11. Then, by repeatedly moving the gantry 11 back and forth, the loop 3
A is given a tensile force, and finally the loop 3A is broken and
The raised embroidery portion 41 is formed.

As described above, the embroidery thread 3 sewn to the fabric 1
By applying a tensile force to the loop 3A and cutting it,
The loop 3A is pulled out to form a brushed embroidery portion 41 composed of a brushed hair 40 with a long bristle like mohair, and has a soft feel and a three-dimensional feel that is not available in conventional embroidery. The brushed embroidery portion 41 having a comfortable texture can be formed. Therefore, if the brushed embroidery portion 41 having such a new design is formed on clothes or the like, it is possible to further enhance the decorative effect and enhance the commercial value. The raising operation for applying a tensile force to the loop 3A of the embroidery unit 2 to cut the loop 3A can be performed artificially. However, if a raising device is used, the raising can be efficiently performed in a short time, and labor can be saved. Further, by using the automatic embroidery machine 10 for sewing the embroidery section 2 on the cloth 1 as the driving means of the capture needle 15, the sewing step of the embroidery section 2 and the raising step of the embroidery section 2 can be performed continuously, so that it is extremely possible. While being efficient,
There is no need to set the fabric 1 again. Furthermore, since the catching needle 15 for cutting the loop 3A by applying a pulling force to the loop 3A of the embroidery thread 3 is attached to the embroidery head 13 of the automatic embroidery machine 10 so as to be able to move up and down, when the embroidery part 2 is sewn to the fabric 1, , The capture needle 15 can be held in a state pulled up by the stopper shaft 28,
There is no fear that the capture needle 15 will get caught on the embroidery unit 2 when sewing the embroidery unit 2. In addition, after the sewing process of the embroidery unit 2, it is possible to set the capture needle 15 to be in contact with the embroidery unit 2 by a simple operation of rotating the mounting shaft 25. In addition, the raising device for raising the embroidery portion 2 supports a large number of capture needles 15 as a support base.
The embroidery section 2 has a very simple structure in which it is fixed to the mounting seat 17, and the sewing process of the embroidery section 2 and the embroidery process can be performed simply by assembling such a simple raising device to the existing automatic embroidery machine 10. The raising process of the portion 2 can be performed continuously, which is extremely efficient, and embroidery made of raised can be easily formed.

As described above, one embodiment of the present invention has been described in detail, but the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, an example in which an automatic embroidery machine is used as the driving means has been described. However, the present invention is not necessarily limited to the automatic embroidery machine, and may be assembled to a dedicated device for moving a capture needle along an embroidery portion. The basic structure of the raising device such as the arrangement of the capture needles and the shape, material, arrangement or mounting structure of the support base on which the capture needles are implanted may be appropriately selected.
