Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spinning machine, particularly a bundled spinning device that uses an air vortex to give a false twist to a fiber bundle spun from a drafting device to form a yarn, and more specifically, to Concerning cleaning means.

Compared to conventional ring silk spinning machines, etc., the binding spinning device is 1
Since yarn is produced at a spinning speed of 0 times or more, the draft mechanism of the conventional method causes various problems and makes smooth operation difficult. That is, the parts such as aprons that come into contact with the fiber bundle under pressure are considerably worn out, and cotton is likely to be generated on the way the fibers are wound into the drafting device due to the airflow caused by the rollers.

As a means to solve these problems,
In No. 06, the draft device is covered with a cover, and a single Zakujon mother eve is connected to the nuclear cover, thereby preventing the 6Fv generated from the draft device from scattering into the room, and at the same time, immediately removing it by suction. A device for doing so has been disclosed. However, in this device, the suction efficiency is poor because the entire inside of J is suctioned by one A-blade, and once fluff gets caught somewhere, it tends to accumulate and grow.
It takes an enormous amount of energy to create a suction force that removes even this. Moreover, since suction is only carried out from two places, a strong air current is generated inside the cover, which can even disturb the fleece. As the suction energy increases, it also brings in the cotton that has accumulated or floated on the machine.

The present invention was made in view of the deficiencies of the prior art, and in particular, the present invention was made in view of the deficiencies of the prior art, and in particular
This is a further improvement on the device described in No. 515.

That is, in Japanese Patent Application No. 57-92515, one
Divide into weights or every two weights, each section 2. A mechanism has been proposed in which the tom rollers each have an end to facilitate changing the apron and removing wrapped fibers after each call. The present invention is provided with a cleaning device W that is added to the tilting mechanism to further remove fluff in an accumulated manner and prevent the rollers from getting wrapped around. It cleverly utilizes a mechanism in which each piece has an end.

In other words, what is the present invention? In the drafting device of a spinning machine, in which the drafting device including the bottom roller is configured as one unit for each spindle or every two spindles, and the side surfaces of each spindle are open ends, the rollers constituting each unit. and/or a first nozzle is provided adjacent to the top and/or bottom surface of the apron, and a second nozzle is provided adjacent to the open end surface of each of the rollers and/or the apron; It is characterized in that two nozzles are connected to a suction air source.

The present invention will be explained in more detail below based on the drawings.

FIG. 1 shows a draft device of a binding and spinning device incorporating a cleaning device according to the present invention, in which a tranquil roller 1, a knot roller 2,
2', middle roller 3, 3', apron 3e, 3e'
, a front roller 4.4' is provided, and furthermore, via a deflection roller 5, an air false twisting nozzle 6 is provided. Of the rollers in each row, the one on the left in the diagram 2
', 3', 4' are the top rollers respectively, and the one on the right side 2
．． 3 and 4 respectively indicate the top rollers. As shown in FIG. 3, these units are divided into two units each to form a door.
They are adapted to be driven separately from drive fill-19, so that a free space 10 exists between two adjacent units.

On the other hand, along the exposed surface of each of the rollers, the first nozzle 1
1, 12.13.14 and 11', 12'.

13' are provided with their openings close to the exposed surface, respectively the top rollers 2, 3.4 and the deflection rollers 5 and gelatome rollers 2', 3'.

It corresponds to 4'.

The nozzles 11', 12', and 13' are attached to the machine frame 15.
The nozzles 11, 12, 13, and 14 are connected to a top duct 18 that forms part of the cover 17.

Further, the connecting ducts 19 protruding from the lower part of the free space 10 side of the ducts 16 and 18 can be freely separated from each other through the corresponding openings 20 of the ducts 18 and the openings 20 of the ducts 18 through packings or the like. being done.

The cover 17 including the top duct 18 has a hinge 2 at its lower part.
When in the operating state shown in FIG. 1, the connecting duct 19 and the opening 20 face each other and the draft device The draft device is fixed on the top and can be rotated to the right by releasing the hooking device to expose the draft device. Also Geratom Duct 16117tiJ
E is connected to a suction air source (not shown), so that in the illustrated operating state all nozzles 11, 12, 13
14: 11', 12', 13' communicate with the suction source.

End faces shown by dotted lines in Figure F1 rise from the connecting duct 19 so as to face the end faces of the rollers 2, 3, 4°5 and 2', 3', 4'. Second nozzles 22, 23, and 24 are provided from the end duct 21 in proximity to the end faces of each of the rollers. Nozzle 22 here
The nozzle 23 is the middle roller 3, 3' and the apron 3e.

3e': The nozzle 24 corresponds to the end surfaces of the front rollers 4, 4' and the deflection roller 5. As mentioned above, the end side duct 21 is an extension of the connecting duct 19, and the opening 20
What happens when it is activated? , since it protrudes from the atom duct 16 and is connected to the connecting duct 19, the second nozzle 2
2, 23, and 24 all communicate with a suction air source connected to the duct 16.

The operation of the present invention having a diagonal configuration will be explained.

The fiber bundle is supplied from below in FIG. 1, is introduced into the drafting device consisting of the series of rollers through the truncate 1, and receives the required draft. The yarn is formed into a yarn shape, and while its shape is maintained by the deflection roller 5, it is sucked into the air false twisting nozzle 6, pulled out as a yarn in the direction of arrow A, and wound into an appropriate package (not shown).

Each group of rollers rotating at high speed generates accompanying airflow on its surface as it rotates, and the accompanying airflows of the pit and top rollers and the apron meet and collide at their tips, but due to the gap with the draft member provided in front. Since the roller is narrow, it tends to blow out in the lateral direction, that is, along the surface of the roller toward the end surface. This lateral airflow causes free fibers to be generated on the end face side from the fiber bundle that is expanding and advancing in a curved shape, and is a cause of roller wrapping, but in the present invention,
The loose fibers are immediately suctioned and removed by the second nozzles 22, 23, 24 provided in the end-side duct 21, thereby preventing such adverse effects.

Furthermore, floating fibers that are attached to and wound up on the surfaces of the rollers and aprons are also
Since it is immediately sucked by 1' to 13', defects such as roller wrapping or uneven drafting do not occur.

In the present invention, the suction nozzle is placed close to the surface of each roller on all exposed surfaces and end faces of the rollers, so that the rollers can be efficiently cleaned without sucking in more air than necessary. It can be executed. In particular, it takes advantage of the free space of the roller yiM+M1, which is a unique feature of the unique two-spindle independent draft device. Since it is now possible to clean the end surfaces of the dust rollers while they are in operation, the time the machines are stopped for removing fluff is drastically reduced.

Furthermore, the duct is built into the cover that essentially covers the entire draft device, making it easy to use! Get a clear structure and make it.
