BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a draft device in a spinning machine, and more particularly to a spinning machine in which rotation of a draft roller that requires a necessary weight and a delivery roller can be started and stopped as desired.

0002

[Prior Art] In a draft device of a conventional spinning machine, a back roller is provided for each spinning unit from a back roller line shaft that is connected to a drive section at the end of the machine base and extends along the machine base. Rotation is transmitted through a clutch. Further, the rotation of the middle roller and the front roller is directly transmitted from the drive section at the end of the machine. Therefore, back roller, middle roller,
The rotation of each draft roller of the front roller can be driven for each spindle for the back roller, but the other draft rollers, the middle roller and the front roller, must be started and stopped for each spindle. It is now impossible to do so.

[0003] Furthermore, the rotation of the delivery roller that sends out the yarn spun from the drafting device is directly transmitted from the drive unit at the end of the machine, similar to the middle roller and front roller, and the rotation is transmitted directly to each spindle. It is now impossible to start or stop the system.

[0004] In this conventional spinning device, when spinning yarn using long fibers, the middle roller, front roller, and delivery roller of the drafting device are - Fibers tend to wrap around the rollers, and once they start wrapping around the rollers, they wrap tightly around the rollers for more than one turn. When the fibers are wrapped around the rollers, these rollers continue to rotate to remove the wrapped fibers. I had to. Particularly in recent years, as higher draft speeds have been required, front rollers and delivery rollers are rotating at high speeds of 2,000 revolutions per minute, making removal work using tools such as sickles increasingly difficult and dangerous. The reality is that there are. For this reason, in some cases, the work is continued without cleaning the weight around which the fibers are wrapped, leaving it as a missing weight.

[0005]

[Problems to be Solved by the Invention] The present invention was made in view of the problems of the prior art, and its purpose is to solve the problem when fibers are wrapped around draft rollers or delivery rollers. To provide a spinning device that can safely perform repair work by stopping only the spindle alone.

[0006]

[Means for solving the problem] Rotation is transmitted from the line shaft of each roller to each draft roller, middle roller, front roller, and delivery roller of each weight via a clutch. The rotation of each of the rollers, which requires a necessary weight, can be started and stopped as desired.

[0007]

[Operation] Until now, the back roller has been able to be driven for each spindle, but in addition, the middle roller, front roller, and delivery roller of each spindle can also be driven from the line shaft via a clutch. Since the rotation of the weight is transmitted, any weight can be stopped and started at will, and repair and inspection work can be carried out safely on any weight, regardless of whether work on other weights continues.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the spinning apparatus of the present invention will be described with reference to the accompanying drawings. For convenience of explanation, the drawings show one spindle in a five-wire type spinning apparatus.

In the figure, 1 is a pair of upper and lower fifth rollers 1.
The back roller includes a pair of upper and lower fourth rollers 1b, and an apron belt 1c is mounted on the fourth roller 1b. 2 is a middle roller consisting of a pair of upper and lower third rollers 2a and a pair of upper and lower second rollers 2b;
An apron belt 2c is mounted on the roller 2b. 3 is a front roller, and 4 is a delivery roller that rotates in contact with the nip roller 5. Reference numeral 6 denotes a trumpet guide for guiding the sliver S pulled out from a can (not shown) to a draft device, and 7 denotes the front roller 3.
8 is a cutter, 9 is a thread waste suction tube, and 10 is a slab catcher.

Next, the drive mechanism of the back roller 1, middle roller 2, front roller 3, and delivery roller 4 will be described.

11 is a line shaft for driving the back roller 1; 11a and 11b are the line shafts for driving the back roller 1;
This is the axis of the fifth roller 1a and the fourth roller 1b that make up the roller. 12 is a clutch provided on the line shaft 11, and this clutch 12 and the shaft 11a of the back roller 1,
11b, a belt 13 is spanned over. Here, the rotation of the line shaft 11 is transmitted to the back roller 1 by the clutch 12, the belt 13, and the shafts 11a and 11b, but the rotation of the line shaft 11 is not transmitted to the belt 13 due to the operation of the clutch 12.
a and 11b are also not rotated, and back roller 1
rotation is stopped. Further, the middle roller 2 rotates by being transmitted with the rotation of the line shaft 14, but in order to do so, a clutch 15 provided on the line shaft 14, a third roller 2a constituting the middle roller 2, and a second roller 2b
A belt 17 is stretched between the shafts 16a and 16b of the middle roller 2, and like the back roller 1, the rotation of the middle roller 2 is stopped or started by operating the clutch 15. Furthermore, in the same manner, a clutch 19 is provided on the line shaft 18 for driving the front roller 3, and a belt 21 is stretched between the clutch 19 and the shaft 20 of the front roller 3. , the rotation of the front roller 3 is stopped or started by operating the clutch 19. Similarly, the delivery roller 4 is provided with a clutch 23 on the line shaft 22 for driving the delivery roller 4, and the clutch 23 and the delivery roller are connected to each other.
A belt 25 is stretched between the delivery roller 4 and the shaft 24, and rotation of the delivery roller 4 is stopped or started by operating the clutch 23.

Now, the above-mentioned clutch is an electromagnetic clutch, and in a weight consisting of a back roller 1, a middle roller 2, a front roller 3, and a delivery roller 4,
When the slab catcher 10 detects a slab, the cutter 8 first cuts the yarn Y and stops the middle roller 2 and back roller 1, and then the cutter 8 and front roller 3
The thread whose both ends have been cut between the middle roller 2 and the middle roller 2 is suctioned and removed by the thread waste suction pipe 9, and then transferred to the delivery roller 4,
Then, the front roller 3 is stopped, and as a result, the fibers wound around the roller can be easily removed.

At the time of starting, the electromagnetic clutch is electrically operated to start the delivery roller 4 before or simultaneously with the front roller 3, and then the middle roller 2 and the back roller 1 are started in this order. Therefore, it is also possible to provide a control mechanism to sequentially start the rollers according to a fixed time difference.

By starting the rollers 4, 3, 2, and 1 as described above, the tip of the sliver can be fed into the spinning nozzle 7 in a thin state like the tip of a brush when restarting when the thread breaks, and the nozzle Trouble such as clogging can be prevented.

[0015] The clutch interposed between the line shaft and each roller may be of any mechanism, and is optional, but it should be as small and lightweight as possible, or one that has a braking function. It is desirable that Furthermore, although the above embodiments have been described by taking a five-wire spinning device as an example, it goes without saying that the present invention can also be applied to three-wire, four-wire, etc. spinning devices.

[0016]

[Effects of the Invention] As explained in detail above, the present invention provides the back roller, middle roller, and front roller of each weight.
Rotation is transmitted from the line shaft of each roller to each draft roller and delivery roller of the roller via a clutch, and the required weight starts the rotation of each roller as desired. Because it can be stopped, rotation is transmitted from the line shaft to the middle roller, front roller, and delivery roller of each weight via a clutch, so any weight can be stopped at will. Since it is possible to stop any weight and perform repair or inspection work regardless of whether work on other weights continues, these tasks can now be performed safely. This eliminates the problem of continuing work without repairing a weight with fibers wrapped around it. Furthermore, the present invention is not limited to the above case, and each roller of each weight can be started and stopped freely according to a request.
