Referring to the operation of the conventional technology configured as described above is as follows.

First, in order to set the number of shapes in the fabric, if the work content is input to the control unit (not shown), the control unit transmits commands to the x and y axis driving motors 122 and 136 and the main axis driving unit.

Therefore, when the x-axis drive motor 122 is operated by the command transmitted from the control unit, the shaft 120 rotates the driving timing pulley 116 coupled forward and reverse rotation, thereby driving the drive The timing belt coupled to the timing pulley 116 is moved forward or backward to move the slider 114.

As described above, when the slider 114 is moved forward or backward, the connector frame a 112 pushes and pulls the embroidery frame 104, and at the same time, the rear of the embroidery frame 104 stays in a fixed position. Sliding moves in.

When the embroidery frame 104 is moved forward or backward as described above, the needle provided in the head 106 is embroidered while moving up and down by the power transmitted from the main shaft driver.

If you want to move the position in the process of embroidering as described above, if the control unit transmits a command to the y-axis drive motor 136 forward and reverse rotation, the shaft 134 is rotated while The driving timing pulley 130 is rotated in the forward and reverse directions. As a result, the timing belt, part of which is wound around the driving timing pulley 130, moves forward or backward.

Accordingly, the slider 128 advances or retracts the embroidery frame 104 while pushing and pulling the connector frame b 126, and at the same time, one end of the embroidery frame 104 is in the fixed position. Sliding in).

As described above, when the embroidery frame 104 moves, the needles provided in the head 106 are embroidered on the cloth while moving up and down in the same manner as described above.

At the same time, a portion of the power transmitted from the main shaft drive unit rotates the driving sprocket 144 while being transmitted through the shaft a 142. Accordingly, the driven sprocket 148 is transmitted while the power is transmitted through the chain 146. Will rotate.

Subsequently, when the driven sprocket 148 rotates to rotate the shaft b 152 and the cam 154 together, the roller 156 is the cam 154 because the control unit does not transmit an operation command to the solenoid. The cam 154 and the shaft b 152 are in a state of only idling because they are not coupled to the cam. Thus, the rod 164 remains in its original position such that the cutter a 168 remains stationary.

At the same time, as the drive gear 178 rotates by the rotating shaft a 142, the driven gear 176, which is geared, is rotated together with the shaft c 174, which causes the tip of the shaft c 174 to rotate. Hook 108 coupled to is rotated together.

On the other hand, if you want to supply a single thread of a different color in the process of embroidering the fabric, the lower thread that was supplied first must be cut. At this time, when the control unit sends an operation command to the solenoid, the hinge shaft 160 is connected to the lever 158. Ascending together causes roller 156 to engage cam 154.

As a result, the roller 156 is coupled to the cam 154 that is idling and flows within a predetermined range, and the lever 158 rotates about the hinge shaft 160.

Therefore, when the pusher 162 installed at the rear end of the lever 158 moves forward and backward while moving left and right, the trimmer shaft 166 is rotated by the rod 164 while the cutter a 168 rotates. In this case, the cutter a 168 pushes the upper thread of the needle side to the outside and returns to cut the upper thread and the lower thread of the cloth toward the cutter b 170.

When the cutting operation is completed as described above, the control unit transmits a command to the step motor 200 installed in the color change driving unit 180.

By rotating the driven gear 196 through the drive gear 198 while the step motor 200 rotates in the forward or reverse direction according to the command transmitted as described above, the driven gear 196 rotates the cam shaft 194. The roller 192 is pushed or pulled while the block 184 moves forward or backward on the guide rod 188.

Accordingly, the block 184 moves the head 106 to the position where the upper thread of the corresponding collar is supplied while the rod 182 moves forward and backward.

In this case, when the sensor pointer 190 installed on the front of the block 184 is checked on any one of the plurality of sensors installed on the panel, information about this is transmitted to the control unit to stop the operation of the step motor 200. As a result, the head 106 reaches a position where the collar of the upper thread is changed and stops.

Subsequently, the control unit transmits an operation command to the x- and y-axis driving motors 122 and 136 to move the embroidery frame 104 forward and backward as described above, and at the same time, the needles provided in the head 106 are upward, Embroider the fabric by doing a lower movement.

As described above, when the connector frame a 20 is moved forward or backward, the roller 18 coupled to the guide groove 22 is pulled or pushed, so that the embroidery frame 4 is on the table 2 in the x-axis. Will be moved in the direction.

At the same time, the connector frame b 40 positioned at the rear of the embroidery frame 4 is in a fixed position, between the guide rollers 46 at the upper end of the supporter 44 of the linear motor 50 and the support controller 48. The upper side of the slide rib 42 is moved, which causes the embroidery frame 4 to move forward or backward while being guided in the x-axis direction.

As described above, the power transmitted from the main shaft drive unit 16 in the process of moving forward and backward of the embroidery frame 4 is transferred to the shaft c 90 so that the needle provided in the head 12 moves up and down. Have the fabric embroider.

If the position is moved in the process of embroidering as described above, the control unit 28 transmits a stop command to the linear motor 26, and at the same time to transmit the operation command to the linear motor (50). do.

Therefore, the linear motor 50 moves the supporter 44 while moving forward or backward. As a result, one surface of the slide ribs 42 located between the guide rollers 46 is pushed or pulled, so that the connector frame b is moved. 40 moves in the y-axis direction, and at the same time the embroidery frame 4 slips on the table 2.

When the embroidery frame 4 is moved in the y-axis direction as described above, the roller 18 located at one end of the embroidery frame 4 is formed with a guide groove 22 formed on the front surface of the connector frame a 20 that is stopped. ) Rotates along the inside and moves in the y-axis direction. As described above, when the embroidery frame 4 is moved, the needle provided in the head 12 moves the up and down in the same manner as described above to embroider the fabric.

On the other hand, unlike the above, when the motor 87 of the monoaxis table 77, which has a different structure on one side and the rear of the embroidery frame 4, is operated by receiving a command from the control unit 28, the screw ( 85 rotates the pallet 83, and the pallet 83 slides along the bed 81.

Subsequently, when the control unit 28 wants to move the embroidery frame 4 in the x-axis direction and the y-axis direction, the control unit 28 commands a motor 87 located at one side and the rear of the embroidery frame 4, respectively. By selectively transferring it to flow on the table 2, the embroidery is embroidered in the same manner as described above.

In addition, when the xy system 89 having a structure different from the above and installed on the back of the embroidery frame 4 receives a command from the control unit 28, the embroidery frame 4 according to a position to be embroidered To move in the x-axis direction or the y-axis direction.

In this case, when the control unit 28 transmits a command to the x-axis linear motor 91 to move the embroidery frame 4 in the x-axis direction, the y-axis linear motor 93 is moved to the embroidery frame 4. And flow in the x-axis direction on the table (2).

Unlike the above, when the control unit 28 transmits an operation command to the y-axis linear motor 93, the y-axis linear motor 93 is maintained in the state where the x-axis linear motor 91 remains at the current position. Command to cause the embroidery frame 4 to flow in the y-axis direction.

Also, unlike the above, when the xy table 95 installed on the back side of the embroidery frame 4 receives a command from the control unit 28, the embroidery frame 4 depends on a position to be embroidered. ) Is selectively moved in the x- and y-axis directions.

At this time, if the control unit 28 transmits the operation command to the x-axis motor 113 to move the embroidery frame 4 in the x-axis direction, the screw b (111) by the x-axis motor 113 Rotates left and right to move the pallet 109 forward or backward, which causes the pallet 109 to slide along the bed 107 while moving the embroidery frame 4 on the table 2 on the x-axis. To flow in a direction.

Unlike the above, when the control unit 28 transmits an operation command to the y-axis motor 105, the screw a rotates left and right to move the upper base 101 forward or backward, thereby the upper base. 101 is slid along with the pallet (109) along the bed (99). Therefore, the embroidery frame 4 located above the pallet 109 flows in the y-axis direction on the table 2.

Subsequently, a part of the power of the main shaft drive unit 16 transmitted to the shaft c 90 as described above is transmitted to the shaft a 54 to rotate the drive gear 58, thereby driving the gear gear 58 with the gear. The driven gear 60 that is engaged rotates the hook 14 while rotating together with the shaft b 62.

Thus, the hook 14 is rotated so that the single thread is pulled out and tied to another single thread moving downward along the head 12. At this time, the cutter b 68 is in a stopped state because the action force is not transmitted through the power transmission unit 70.

On the other hand, in the process of embroidering the fabric to supply a single color of different colors to form a variety of patterns to be cut first supplied single thread, in this case, the control unit 28 in operation command to the linear motor 84 The rod 82 is advanced with the clamp 80 by the action force.

Therefore, when the trimming shaft 72 is rotated while the links a, b (76, 78) are rotated by the moving clamp 80, the cutter b 68 rotates outwards together to push out some necessary single thread. .

Contrary to the above, when the control unit 28 transmits the command to the linear motor 84 again to move the rod 82 backward, the clamp 80 moves together with the rod 82 while the link a, b (76, 78) is rotated in the reverse direction.

Accordingly, the trimming shaft 72 is rotated in the reverse direction to return the cutter b 68 to its original position, thereby protecting the needle-side upper thread outside the cutter b 68 and returning to the original position. Unnecessary cloth upper thread and lower thread are cut while moving toward the cutter a (64) side.

When the upper and lower threads of the cloth are cut as described above, the control unit 28 transmits a stop command to the linear motor 84 so that the cutter b 68 is in a stopped state.

On the other hand, unlike the above, the operation sequence of the mono Axis table 12 coupled to the rod 82 is as follows.

First, when the motor 131 receives the operation command from the control unit 28, the screw 129 is rotated by the motor 131, and the pallet 127 is moved forward and backward. The rod 82 is rotated forward and backward by the pallet 127 to rotate the cutter b 68 as described above.

On the other hand, when the cutting operation of the upper thread and the upper thread as described above is finished, the control unit 28 transmits the operation command to the linear motor 98 to advance or reverse the rod 92 to push the head 12. .

At this time, the range in which the linear motor 98 is moved forward or backward while the linear motor 98 is operated is to the needle position to which the upper thread of the corresponding color selected from the operation unit 30 menu is supplied. Operate the linear motor 98 as much as possible.

Accordingly, the head 12 slides along the rail 86 provided above the arm 88 by the rod 92 moving forward and backward as described above, and at the same time, the power supplied from the main shaft drive unit 16 A part is transferred to the shaft c (90) so that the needle for supplying the single thread of the corresponding color is moved up and down, so that the water is placed on the cloth installed in the embroidery frame (4).

On the other hand, unlike the above described when the operation sequence of the mono Axis table 131 coupled to the rod 92 as follows.

First, when the motor 141 receives the operation command from the control unit 28, the screw 139 is rotated left and right by the motor 141 to move the pallet 137 forward and backward, This causes the rod 92 to push or pull the head 12 while moving forward and backward, as described above, by the pallet 137.
