The present invention relates to an embroidery device of a sewing machine for embroidery for embroidering (embroidering work) on the fabric itself to be used in clothing, especially dress-type clothing.

In general, the conventional sewing machine for embroidery work is to move the embroidery needle of the embroidery thread to move up and down according to the pattern shape for the embroidery work to put the embroidery thread into the embroidery thread or the embroidery needle tape tape embroidery To come in the form of sewing on the fabric itself.

Therefore, the fabric should be kept in a taut state in accordance with the up and down operation of embroidering by the method described above. At this time, after cutting the fabric of a certain standard (according to the capacity of the embroidery apparatus) to the embroidery apparatus itself, The gripper is held in the shape of a gripper and then pulled on both sides thereof to keep the fabric in a taut state.

However, by this method, after the work on the fabric already mounted on the embroidery machine of the cut standard is finished, it is taken out of the embroidery machine, and then the fabric itself is cut back on the embroidery machine for the next process. Since embroidery work has to be performed, the work is interrupted by the process of remounting the fabric, which is not only cumbersome but also has a disadvantage in that the production efficiency is extremely reduced.

In addition, the embroidery needle drive device that takes the embroidery has a disadvantage that the operating radius is extremely short, it is not suitable to embroider with a relatively large radius.

The present invention has been devised to eliminate such drawbacks, and the fabric is automatically supplied, but the fabric is kept taut and the series of devices for conveying the fabric can be moved to the left and right directions, thereby reducing the operating radius of the embroidery bars.

Reference numeral 100 denotes an embroidered needle plate, and 101 denotes that the fabric 102 has left and right forward compression rollers 7, 7 ', and 10, 10' of the fabric supply rollers 53, 54, respectively. A chain that is installed to serve as an auxiliary role when a roll is moved from the left and right rear compression rollers (8) (8 '), (11) (11') to the winding rollers (54 ') and (54'). A needle 101 ′ fixed at an outer circumferential surface of 101 is penetrated into the fabric 102 to assist movement.

The present invention configured as described above will be described in detail for the operation and effect.

First, as shown in FIG. 11 of the accompanying drawings, first, the fabric 102 wound on the fabric feed roller 53 or 54 by hand, respectively, is left-front pressure roller 7, 7 ′ or ( 10) (10 '), so that the fabric is inserted into the needle 101' of the chain 101, and then again between the left rear pressure roller (8) (8 ') or (11) (11') Take out to the specification and wind up again to the winding roller (53 ') or (54') to complete a series of preparation work.

At this time, adjusting screws 25, 26, 25, 26 ', 27, 28, 27' installed at both ends of the transverses 5, 5 ', and 9, 9', respectively. 28 ') to the left front and rear pressure rollers (7) (8') and right front and rear pressure rollers (10) and (11) across the span (5) (5 ') and (9) ( Guide holes 13 and 14 on the guide holes 5a, 5b, 5a ', 5b', 9a, 9b, and 9a ', 9b' formed in front and rear of 9 '). ), (13 ') (14'), (15) (16) (15 ') (16') to move left front pressure roller (7) (7 '), left rear pressure roller (8) (8' ), While the distance between the right front pressure roller (10) (10 ') and the right rear pressure roller (11, 11') is widened, the fabric 102 is attached and gripped in the state shown in FIG. . In this state, operate the adjusting screws 25, 26, 25 ', 26', 27, 28, 27 'and 28', respectively, and return them to their original positions. Recommended springs (17) (18), (17 ') (18') for each of 21 (22), (21 ') (22'), (23) (24) and (23 ') (24'), respectively. , (19) (20), (19 ') (20') presses the front left and rear pressure rollers (7) (8 ') and the right front and rear pressure rollers (10) and (11), so that the fabric (102) Between the left front pressure roller (7) (7 '), the left rear pressure roller (8) (8'), the right front pressure roller (10) (10 ') and the right rear pressure roller (11) (11'). The preparatory work is done by being pressed from.

In this state, when the motor (not shown) is driven as shown in FIGS. 2 and 8, the connecting shaft 12 'is rotated by the belt 81 from the motor shaft 80. The right rear pressure roller 11 and the rear pressure roller 8 are rotated by the rotation of the connecting shaft 12 ', and each of the right rear pressure roller 11' and the left rear pressure roller 8 'are pressed. Also rotated in opposite directions to each other, and also by the belt 29 connected between the connecting shaft 12 in the center of the connecting shaft 12 'to rotate the connecting shaft 12' the rotating force of the connecting shaft 12 ' Since the left front pressure roller 7 'and the right front pressure roller 10' are coaxially connected with the connecting shaft 12, the left front pressure roller 7 and the right front pressure roller are eventually rotated. 10 will rotate respectively.

The rotation of the front left and rear pressure rollers 7 'and 8 and the right front and rear pressure rollers 10' and 11 are respectively driven at the ends of the driving rollers 30 and 31, respectively. Since the driving rollers 30 'and 31' are rotated, respectively, the rotational force of the driving roller 30 is transmitted to the clutch bearing roller 34 of the fabric pull mechanism 32 by the belt 36, and thus the fastener ( 51, the rotational force of the drive roller 31 is rotated by the belt 25 'and the rotational force of the far end pull mechanism 31' by the belt 37 'is the clutch bearing of the far end pull mechanism 33'. It is transmitted to the roller 34 'to rotate the fastener 52'.

Since each of the fasteners 51, 51 ', 52, 52' is rotated, the supply rollers 53, the winding rollers 53 ', the supply rollers 54, and the winding rollers, which are respectively attached thereto, are rotated. The 54 'is rotated in opposite directions so that the supply and fragrance of the fabric 102 is automatically performed.

As shown in FIG. 2 attached by the supply of the fabric 102 as described above, the fabric 102 is moved on the embroidery needle plate 100 while being moved. Embroidery work is made to the fabric 102 by the operation of the embroidery needle (N).

At this time, since the pattern itself is not formed only by the movement of the fabric 102, that is, the movement from the front to the back of the fabric 102, the fabric 102 is moved backward or leftward. In this case, embroidery is formed in which the movement to the right should be freely performed.

Control of this operation is to be embroidered on the monitor (C ') by the computer (C) is inputted, and the above method of controlling this is a method of automatically adjusting the rotational force of the motor driving the device It will be built by the concrete description as follows.

That is, the front fabric 102 moving from the front to the back, that is, the supply rollers 53 and 54 to grip the holding rollers 53 'and 54' and the left front and rear rollers 7 and 7 ', (8) (8 ') and right front and rear rollers (10), (10'), (11) (11 ') and transverse (5) (5') (9) (9 ') with rotatably mounted them; To move left and right, as shown in FIGS. 2 and 6 of the accompanying drawings, the belt 38 rotates while the belt 38 is rotated by driving a motor (not shown). Since the left rear guide sphere (4a) fixed to the lower portion of the transverse (5) is embroidered because a series of devices for holding the fabric 102 in the above on the rear guide rod (2 ') is moved to the left and right Even when the needle N is reciprocated in place and manually performed, embroidery work is performed according to the pattern shape as described above. This left and right movement is made by adjusting the rotational speed and direction of the motor, and this is done by the computer C.

Meanwhile, as described above, the fabric 102 is moved from the front to the rear, so that the fabric 102 is supplied, but the driving thereof is based on the rotational speed and direction of the motor shaft 89 of the motor (not shown). This is also done by the computer (C) already input.

However, when the fabric 102 is moved from the front to the rear, that is, when the fabric 102 is moved backward by the rotation of the motor shaft 89, the supply rollers 53 and 54 and the winding roller 53 '( By the same rotation 54 '), the fabric 102 itself is loosened, and the embroidery work is not smooth.

At this time, the clutch bearing rollers 34 and 35 of the distal end pull mechanisms 32 and 33 on the supply rollers 53 and 54 side by the rotation of the motor shaft 89 are clutch bearings 77 and 78. Since the rotary shafts 85 and 86 rotate in the opposite direction, the clutch bearings 63 and 64 rotate the disc rotating disks 65 and 66 by reverse rotation of the rotary shafts 85 and 86. It is rotated, but this is moved to the state that is pressed to the disc plate 59, 60 of the cork material by the elastic force of the spring (69) (70), so that the rotary shaft (85) (86) is the braking force (which is the stop state It does not mean that it does not rotate the same as the rotational force of the motor), so that it takes a state that the take-up rollers 53 'and 54' which hold the rear, i.e., the distal end 102, rotate while the same as the rotational force of the motor One feed rollers 53 and 54 are gradually supplied as described above to keep the fabric 102 in a taut state, At this time, the clutch bearing rollers (34 ') of the fabric pull mechanisms 32' and 33 'of the fabric pull mechanisms 32' and 54 'on the winding rollers 53' and 54 'are described above. 35 ') rotates the rotary shafts 85' and 86 'by the clutch bearings 77' and 78 'in the same direction as the motor shaft 89 of the motor, so that the winding rollers 53' and 54 'are rotated. ) Is naturally rotated by the same rotation as the motor shaft (89).

On the contrary, the reverse rotation of the motor shaft 89 causes the need to move the fabric 102 from the rear to the front, which is also generated according to the embroidery shape, and the control thereof is also performed by the computer C as described above. This is achieved by controlling the rotational speed and direction of the motor.

At this time, the supply rollers 53 and 54 are rotated by the motor shaft 89 at the same rotational speed of the motor shaft 89 by the reverse rotation of the motor shaft 89. The rotation of the clutch bearing rollers 34 and 35 of the 33 is transmitted to the rotation shafts 85 and 86 by the clutch bearings 77 and 78, which are then transmitted to the binding ports 51 and 52, respectively. Since it is possible, the clutch bearings (63) (64) is just idle as it has no effect on the rotation shaft (55, 56).

On the contrary, the clutch bearing rollers 34 'and 35' of the fabric pulling mechanisms 32 'and 33' on the side of the rollers 53 'and 54' are driven by the clutch bearings 77 'and 78'. Instead of idling, the brake shafts 55 'and 56' are braked by the clutch bearings 63 'and 64' (which does not mean stopping, but does not rotate the same as the rotational force of the motor). This is caused by the disc turning disks 65 'and 66' being pressed against the disc plates 59 'and 60' by the spring force 69 'and 70'.

Therefore, even when the fabric 102 is moved forward or rearward by such an operation, the fabric 102 itself is always embroidered while maintaining a taut state.

In addition, the movement distance sensor 82 mounted on the left rear guide sphere 4a represented in FIG. 2 is attached to the left and right sides by the belt 38. The movement distance is measured by reaching the sensor 83 mounted on the substrate 1, and the measured movement distance is applied to the computer C to adjust the movement distance.

In this way, when the fabric 102 is moved to the left or right, if the fabric 102 is moved backward or forward, the fabric 102 is moved diagonally when viewed from the embroidery needle (N) so that embroidery work can be made smoothly. do.

In this way, according to the fabric pull mechanism of the present invention, in the supply and winding of the fabric to be embroidered, the embroidery work is always carried out in a tense state, and the embroidery needles hold the leg even when the embroidery needles perform the embroidery work while moving in place. By moving a series of devices to the left and right, or changing the conveying direction of the fabric, the embroidery work continues to be performed to increase the work efficiency and ultimately reduce the production cost.
