Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixed clearer device used in a draft device of a spinning machine.

(3) Various types of clearer devices have been used for draft devices of spinning machines. For example, you can clean the surface of Ronilla by bringing an endless piece of Kuryara cloth into contact with the upper or lower part of the roller and rotating it continuously or intermittently, or by preparing a rod-shaped Kuryara with the Kuryara cloth wrapped around it and glued to the surface. The roller surface is cleaned while the roller is brought into contact with the upper or lower part of each roller and rotated by friction.Cleaning with this rod-shaped cleaner has shown excellent effects on spinning draft equipment for short fiber spinning. 1. The stick-shaped kuriara, which is widely used for this purpose, accumulates short fibers and immature cotton taken from the roller surface in the rod-shaped kuriara, which has a relatively small diameter, so it is necessary to periodically clean the rod-shaped kuriara. There is, and it takes a lot of effort.

Therefore, recently, a method has been used in which a plow cleaner is provided above the draft device and the draft device is cleaned by blowing air, which helps to save labor. However, since the plow cleaner blows air from above the draft device, it is not possible to clean rollers where the pack is located below the draft device (4) and has grooves like a tom roller. In particular, pack-bottom rollers have a tendency for short fibers and immature cotton to become clogged in the grooves, and the clogged short fibers and immature cotton cannot be removed by air blowing. Therefore, even today, rod-shaped Kuryara is usually used against Packbot Murora.

However, when a pack uses a rod-shaped Kuryara for the tom roller, various drawbacks occur. In other words, first of all, in terms of quality,
The staple fibers and immature cotton adhere strongly to the grooves, and immature cotton in particular is sticky, so in the case of rod-shaped kuriara, which is rotated when the pack comes into contact with the roller surface, the kuriara part is passive against the roller surface. rotation,
The disadvantage is that the surface velocities are almost the same, and therefore sufficient cleaning cannot be achieved. Furthermore, if short fibers or immature cotton accumulate on the rod-shaped kuryara, the cleaning effect will further deteriorate. Therefore, it is necessary to periodically clean the rod-shaped clara every short operating time to prevent short fibers and immature cotton from adhering to the grooves and becoming unable to be removed by the rod-like clara. This has the disadvantage of being contrary to labor saving. Furthermore, when using a plow cleaner in a draft device, the pack passed between adjacent roller stands is sprayed from above, which acts as a barrier to the air passage, reducing the cleaning effect of the top roller, etc. It has the disadvantage of

Attempts have been made to clean by bringing a rubber-like material into contact with a roller instead of the rod-shaped cleaner.

However, since this method simply brings the rubber-like material into contact with the roller, when used for pack bottom rollers, it is difficult to completely remove short fibers and immature cotton attached to the grooves of the roller. Not yet reached.

The present invention eliminates the drawbacks of the cleaning device for the pack bottom roller, has a high ability to remove short fibers and immature cotton from the pack bottom roller, and can significantly lengthen the cleaning cycle. An object of the present invention is to provide a clearer device that can be used more efficiently.

The purpose of the present invention is to provide a roving par located below the roving that runs between the back roller and middle roller of a drafting device, between adjacent roller stands that run parallel to the roller, and a roving par that can be attached and detached from the roller recess of the front and rear YF tom rollers. at least two rovings that are fixed to the roving bar at approximately the center thereof; A bar support member and a plurality of clearing members, each of which has at least a portion that contacts the backbottom roller, is formed of a rubber-like member and is attached to the roving par at intervals so as to substantially correspond to the fritted portion of the backbottom roller. In a fixed clearer device for a spinning frame, the fixed clearer device is configured to include a member, etc., wherein an elastic repulsion mechanism is provided between the rubber member of the clearer member and a receiving portion for the roving parr, and the fixed clearer device is connected to the draft device. Relative positions of the hook part of the support member, the roving par, and the rubber member of the clearer member so that the elastic repulsion mechanism works to press the rubber member against the back bottom roller when attached. This is achieved by a fixed clearer device for a spinning machine, which is characterized by determining the relationship.

The clearer member is formed of a hollow cylindrical rubber member,
A part of the outer peripheral surface of the rubber-like member may be fixed to the roving par so that the back of the drafting device comes into contact with the tom roller. In this case, since the hollow cylindrical rubber member has a repulsive force against compression from the outer peripheral surface, the repulsive force acts as the repulsive force of the elastic repulsion mechanism.

Note that the hollow cylindrical rubber member is fixed to the roving par through a clearer member fixing bar that is inserted into a hollow hole of the rubber member parallel to the roving par and removably fixed to the roving par. Good too. If the roving part of the hollow cylindrical member is fixed in this way,
When the fixed clarifier device of the present invention is removed from the draft device for cleaning, it is possible to shift the position of the contact portion of the rubber member to the back bottom roller and fix it to the roving par again. By shifting the abutting portions, the entire outer peripheral surface of the hollow cylindrical rubber member can be used as the abutting portion, so the rubber member can be used for a long period of time, which is economically advantageous.

Further, the clearer member is formed of an arc-shaped leaf spring having a rubber-like member attached to the outside of one end thereof, and the rubber-like member is attached to the back of the drafting device via a mounting portion having a leaf spring attached to the other end. 3. The roving par may be removably fixed to the roving par so as to come into contact with the roving par. In this case, the repulsive force of the leaf spring acts as the elastic repulsion mechanism.

Furthermore, the length of the roving par is set to be longer than the distance between the roller stands on both sides, and a groove is provided on the inside of the roller stand corresponding to the force, in which the end of the roving par engages, and the fixed clearer device is fixed to the draft device. The hanging IE portion of the support member, the roving par, and the rubber of the clearer member act so that the elastic repulsion mechanism of the clearer member works and the rubber member is pressed against the tom roller when the rubber member is attached to the support member. 3. The relative positional relationship between the shaped member and the groove of the roller stand may be determined. In this way, when a plurality of roving members are attached to the roving par, which is elongated in the longitudinal direction compared to its cross section, the relative positional relationship can be maintained approximately equal for each roving member, and as a result, the rubber-like The back of the member helps to make the pressing force against the tom roller approximately equal.

The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

In one embodiment of the fixed clearer device of the present invention shown in FIGS. 1, 2, 3, and 4, the cross section is approximately oval, and its length is longer than the distance between adjacent roller stands. A plurality of hollow cylindrical synthetic rubber members 1 are attached to a rather short roving par 2. Kuryara parts 1
The length in the longitudinal direction is approximately equal to or slightly longer than the length of the fluted portion 16 of the backbottom roller 1, and the clearer member 1 is arranged with its outer peripheral surface parallel to the axial direction of the backbottom roller and between adjacent roller stands. It is attached to the roving par 2 in correspondence with the position of the free-dead part 16 of. The number of clearer members 1 is the fluted part 1
Corresponding to the number 6, there are usually 4 to 8 pieces. In this embodiment, the roving par 2 of the clearer member 1 is attached to the clearer member fixing bar 3. That is, as shown in FIGS. 2 and 4, a long and thin cross section of the Kuryara member fixing bar 3 is inserted into the hollow holes of the plurality of Kuryara members 1, and the Kuryara member is sandwiched between it and the roving par 2. 11 attached to the roving par 2 with multiple screws 12
In this embodiment, since it is easy to attach the clearer member 1 to the roving par 2 in this way, it is easy to replace the clearer member 1 whose outer peripheral surface has been worn due to contact with the totom roller, and also to loosen the screw 12. By floating the clearer member fixed par 3, the outer peripheral surface of the clearer member 1 is sequentially shifted and packed. It can be brought into contact with the tom roller 7. Therefore, the entire circumference of the outer peripheral surface of one hollow cylindrical clearer member 1 is covered with the back-? Since it can be used as a contact surface for the bottom roller, the life of the clearer member 1 can be extended. .

10 as shown in Figures 1, 2, 3 and 4.
- Fixing the roving par support member 5 to the roving par 2 near both ends thereof at right angles to the longitudinal direction of the roving par 2.

As shown in FIG. 6, the support member 5 includes a back gelato roller L and a middle d? The support member 5 is set to a length that allows the support member 5 to be placed on the tom roller 8. The tip of the supporting member 5 on the side of the pot roller 5 is bent at a right angle, as shown in FIGS. 2 and 4, and serves as a hook 4 for hooking onto the back pot roller 5. The support member 5 has a smooth roller portion 9 (hereinafter referred to as roller recess 9) between the adjacent fluted portions 16 of the pack and the middle roller. The roller concave portion of the tom roller 8 is engaged with the roller recess. At this time, the support member 5 and the roving par 2 are positioned in the roving advancing direction of the draft device by the hooking portion 4. An ingro sheet material 6 a * 6 is placed on the inner surface of the support member 5 and the contact surface with the tom roller I and the middle tom roller 8.
By attaching b*6c, it is possible to prevent the support member 5 from being worn out due to contact with the roller recess 9.

Note that the hanging IL portion 4 of the support member 5 may be formed into an arc shape along the diameter of the roller recess of the pack.

FIG. 5 shows a sectional view of a draft device of a conventional spinning frame.

In the draft device shown in FIG. Therefore, when the air is blown from a blowing collar (not shown) as indicated by an arrow 17, its path is blocked by the rod-shaped clearing collar Ilb, and it is difficult for the air to flow downward to the draft device.

FIG. 6 shows a sectional view of a draft device to which a fixed clarifier device according to an embodiment of the present invention is attached. 1 As is clear from FIG. attached to the draft device. At this time, the position of the fixed clearer device in the traveling direction of the roving is determined by the hook 4 as described above. And the hollow cylindrical Kuryara member in the back? The pack hole of the hollow cylindrical clearer member 1, the position of the surface on the tom roller l side, and the hooking part 5 of the support member 4 are set so that the fixed clearer device can be placed on the draft device and fully latched by being pressed against the surface of the tom roller l.
The fixed clearer device is assembled by determining the relative positional relationship between the roving par 2 and the roving par 2.

FIG. 7 shows an enlarged view of the relationship between the clarifier member 1 and the pack pot murrow 21 when the fixed clarifier device according to an embodiment of the present invention is attached to a draft device. Since the clearer member 1 of this embodiment is made of hollow cylindrical synthetic rubber,
It has an elastic repulsion force as a rubber material and an elastic repulsion force due to the hollow cylindrical shape of synthetic rubber. As shown in an exaggerated manner in FIG. 7, the clearer device of the present invention is configured to move the clearer member 1 by pressing the tom roller 7 (7) 7! Attach by pressing it onto the J-needle section 16. Therefore, the hollow cylindrical clearing member 1 is slightly crushed from a perfect circle and comes into contact with the 7-riute and do portions, and as a result, the free and -ted portions 16
When the surface of the clearing member 10 bites into the grooves of , it becomes K. The rubber surface of the clearer member 1 is kept wedged into the grooves mainly due to the elastic repulsive force resulting from the above-mentioned shape.

On the other hand, since the ryara member 1 is fixed to the draft device and the packget mulolae is rotating, the rubber part of the ryara member will remove the short fibers and immature cotton that have accumulated in the grooves of the fluted portion 16. If it digs into the grooves and scrapes it off, complete removal can be achieved.1゜It is inconvenient if the pressing force of the clearer member 1 against the pack pot roller is too strong or too weak. It is.

That is, if it is too strong, an extra load will be applied to the rotation of the pack sf tom roller I, and the abutting surface of the pack of the clearer member 1 to the tom roller I will be accelerated. If the pressure is too weak, the ability to remove short fibers and immature cotton will decrease. Therefore, in order to obtain an appropriate pressure that is useful for increasing the removal ability, the material of the support member 1 should be taken into consideration. 5, the relative positional relationship between the roving bar 2 and the clearing member 1 is determined.

In addition, if the surface of the hollow cylindrical rubber-like member in this example is given a wavy shape by special processing, it becomes a pack? The ability to remove short fibers and immature cotton from the grooves of the cotton roller can be further improved.

In the fixed clarifier device of the present invention, the clarifier members 1 are arranged at intervals on the roving rod 2 as shown in FIGS. As shown in FIG.
The amount of cleaning required can be greatly reduced. That is, the fixed clearer device of the present invention backs up the rubber member in the pressed state as described above? This is because the structure is such that it comes into contact with the grooves of the cotton p-ray, so short fibers and immature cotton can be scraped off from the grooves. Therefore, unlike the rod-shaped Kryara, which collects almost all of the removed short fibers and immature cotton on its outer surface, the amount of short fibers and immature cotton accumulated on the surface of the Kryara member 1 is significantly less.1. As a result, the cleaning cycle of the clearer member 1 is significantly extended, and may be cleaned once every two months, for example. In other words, it is sufficient to clean the clearer member 1 at the same time as the regular cleaning of the spinning machine, which is normally carried out once every two months.

FIG. 8 shows another embodiment of the present invention. The clearer member 20 in this embodiment is formed of an arc-shaped leaf spring, and a rubber member 21 is attached to the outside of one end thereof, and a mounting portion 22 to the roving bar 2 is provided at the other end. The rubber-like member 21 is packed by the elastic repulsive force of the leaf spring. 7 Tom Roller will be pressed against him. The cross section of the mounting part 22 is U
Because of this, the clearer member 1 can be attached to and detached from the roving bar 2. The rest of the structure of this embodiment is the same as that of the previous embodiment, so a still further embodiment of the present invention is shown in FIG. In this embodiment, the length of the roving bar 2 is
It is extended to a length of 3 m and 13b, and protrusions 15a and 15b are provided at both ends thereof. On the other hand, roller stand 1
3a and 13blC are provided with grooves 14m and 14b for mounting the roving bar 2. In this way, the roving bar 1 is fixed on both sides, and the hook part 4 of the support member 5 is moved back? By hooking the rubber member 1 to the pack pot roller, the position of the rubber member of the clearer member 1 relative to the pack pot roller can be maintained approximately equal for each clearer member, and therefore the pressing force can be made approximately equal for each clearer member. can do.

Since the fixed clarifier of the present invention is constructed as described above, the pack can improve the ability of the cotton roller to remove short fibers and immature cotton1, and the cleaning cycle can be significantly lengthened, contributing to labor savings. Furthermore, the blowing of the plow cleaner does not obstruct the air passage, making it possible to increase the efficiency of use of the plow cleaner.

In addition, the fixed clearer device of the present invention includes a roving bar;
Since a plurality of clearer members arranged between adjacent roller stands can be assembled together and removably attached to the drafting device, there are advantages in that they can be easily managed and manufactured at low cost.
