Description

[Detailed Description of the Invention] The bottom roller group of a spinning machine usually consists of
These are connected, and all the weights are linked together so that they are directly driven by a drive mechanism provided in the gear end frame at one end. In this case, the problem is that when replacing parts, especially when replacing the apron, the 11" apron is removed by cutting it, but when wrapping a new apron, one staff of the bottom roller is removed from the roller stand. .

This work must be done while moving the bottom apron in the longitudinal direction of the roller, making it an extremely tedious task. In addition, even in the case where the fibers are wound on the bottom roller in the fiber passage section, it takes a lot of effort to remove them.In other words, the fibers that have been wound/-1 are moved in the longitudinal direction of the roller and removed. It's virtually impossible to do that, so I take my time and relax.

have to be cut off. In addition, the generated fly fluff especially gets into the narrow areas in the apron, but when removing it, the bottom roller is connected to all the spindles, so there is a limit to the area that the removal means can penetrate, making it difficult to remove it. There are also 9 problems.

Recently, a binding spinning device that spins binding yarn using an air false twisting nozzle, which is a type of static spinning machine, has attracted attention. This bundled spinning device is also capable of high production, which is more than 10 times that of a ring spinning machine.

Because of this, a high draft effect is also required.
In draft equipment. Problems such as those described in iiJ are likely to occur, and this is a major obstacle to practical application. In other words, in the drafting device of this binding spinning device, the apron wears out considerably due to the high speed rotation, and due to the influence of accompanying airflow, the fibers tend to curl (-1), and furthermore, it is easy to generate fluff. Of course, the fiber wrapping [
Measures can be taken to prevent the occurrence of loose fluff, but it is desirable to have measures in the unlikely event that it occurs, as well as measures when replacing aprons. In addition, it is desirable to be able to perform the yarn splicing operation at the middle of each spindle, and to be able to solve the problem for each spindle when a two-layer problem occurs.

The inventors of the present invention focused on the fact that replacing the apron and removing the winding 1.1 fibers on the top roller for one bottom roller can be easily done by moving them in the longitudinal direction of the roller. For the rollers 19, apply 1 IUi L to each weight M, and remove the ends of each bottom roller.In this way, replace the apron with 1 roll and remove the fibers for each call.

Removal of fluff and cleaning operations can be easily performed at the bottom roller end. It was made by sea urchin.

Specifically, one end surface of each bottom roller is open and the other end surface is supported by a bearing with IIEi (-1), a driven mechanism is attached to the shaft, and a common shaft for all the spindles is supported. The drive mechanism IIWfl attached to the bottom roller drive shaft was connected to each of the driven mechanisms having a weight of 1σ.

Shown in the drawing. An example of a three-wire draft device adopted for binding spinning will be described. A back bottom roller 4.3 is rotated by a back bottom roller 4. Middlebot Murora 5. They extend along the front bottom rollers 6 over the entire weight. Each bottom roller 4.
5.6841 # unit, and in order to transmit rotation to each intermediate bottom roller, a driven mechanism is provided at each end, and a bottom roller drive shaft 1.
2.3 is connected to the driven mechanism.

First of all, regarding the backboard)/Mrolla, the gear 7 of the drive shaft 1 meshes with the gear 9 of the intermediate shaft 8, and the gear 10 at one end of the shaft 8 meshes with the gear 9 of the intermediate shaft 8.
Press the key V12 of the backboard) and roller shaft 11).
Y is on. In this case, Botmulola 4 is: 1Q
1111 is supported by two bearings 13 and 14.

Next, regarding the middle bottom roller, the key Y15 of the drive shaft 2 meshes with the gear 17 on the bottom roller shaft 16, and the middle bottom roller 5 is driven by the main 18 on the IIQIl receiver 18. .

The configuration of rotation transmission for the front bottom roller 6 is similar to that of the middle bottom roller 5 described in 1- above.

. Based on such a configuration, the bottom roller drive shafts 1 and 2
．． The rotation of 3 is transmitted from the drive mechanism to the driven mechanism, and there is a gear Otsu 15 etc. as the drive mechanism, and gears 9, 12, 17 etc. correspond to the driven mechanism.

This embodiment is an example of application to a static false twist type binding spinning device, in which the fiber bundle supplied from the guide 19 is passed through the back bottom roller 4. Apron 2 wrapped around middle bot Murora 5
0. Each of the front bottom rollers 6 passes through two parts and enters the air false twisting nozzle 21 through a group of such bottom rollers.

A set of rollers is also available for sale for each call. As shown in FIG. 1, the pressure plate 34 is fixed to the cover device 33 so that the shaft 32 can be opened and closed in both directions.
The shaft 35 is rotatably provided with a pressurizing ring 37 between the two sides of the saddle 36 with approximately 11 digits. The shafts 41, 42, 43 of each top roller 38, 39, 40 are supported by the saddle 36. Therefore, when the cover assembly 33 is locked in the closed state by operating the handle 44, each top roller is pushed away by the bottom roller and can be pressurized by the spring 37.

In addition, since a drive mechanism is provided for each call, it is possible to stop and start each call, and as shown in Figure 1, the backbottom roller It is also possible to interpose a mold sand clutch MC1 on the intermediate shaft 8 related to 4.

However, since a new drive mechanism is provided for each weight 10, it is necessary to prevent fluff from entering there.

For this purpose, the bottom roller and the drive mechanism are separated by a cover.
^11 As shown in Figure 2, lower covers 22 are installed on each bottom roller 4, 5.6F, and
A part of the cover 23 may be provided on the second side of the drive mechanism so as to be continuous therewith.

In the example shown in Fig. 2, bearings 13 and 14 also serve as covers on both sides, and these bearings 13 and 14 are designed to support the t skin movement key V1.
He has 11 points in the pack, including 2 and 11 points. Although it depends on the structure of the bearings 13 and 14, if there is a concern that the lint may adhere to the Qll bearings due to leakage, causing further oil leakage, as shown in Figure 1, Bearings 13, 18.2 of each bottom loaf are placed inside the cover.

In the actual IJ (li example) shown in Fig. 3, each bottom roller's driven machine (within 1 to 'electromagnetic clutches MCI, MC2, MC3
Equipped with That is, since each bottom roller of the device of the present invention is constructed by each weight, the electromagnetic clutch MCI, Pi
By equipping C'l and MC3, all bottom rollers 4 and 5.6 of each weight can be stopped.

It can be started up independently, and the troubleshooting operations described at the beginning can be performed very easily.

Further, when it is necessary to reversely feed the fleece (ID f: i-ke) by reversing the front roller 6.40 during the yarn splicing operation, a reversing clutch (not shown) can be installed.

According to the present invention, since each bottom roller is divided into each spindle, it is possible to manage each heel part, and each bottom roller has an open end, so that when replacing the apron, the roller V for the work of moving in the longitudinal direction
By doing this, you can easily remove the apron from the roller end.
The IQ can be removed and a new apron can be easily wrapped. Roll to Botmurola 11
When removing mushroom fibers, they can be removed from the roller ends in the same way. Also, the removal of composted cotton from each roller section can be done by removing from the open end of the rollers or by using a suction cleaning device. It is advantageous because it can be installed easily.

Furthermore, even if each top roller P becomes difficult, if each heel is provided with a pressure device, the management of each weight can be further promoted.

1-1 An additional effect of the present invention is that since each bottom roller is manufactured with a cow body structure, it is possible to manufacture high-precision rollers with less runout.
This has an extremely favorable effect on spinning quality, and is an effect that cannot be overlooked.
