Description

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

Various types of clearer devices have been used for draft devices of silk spinning machines.

For example, you can clean the surface of the roller 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 offering-shaped Kuryara with the Kuryara cloth wrapped around the surface and gluing it, and then attaching each rod-shaped Kuryara to each roller. The surface of the roller is cleaned by bringing it into contact with the upper or lower part of the roller and rotating it by friction. Cleaning using this rod-shaped clearer has an excellent effect on the horizontal paper drafting device for short fiber spinning, and is therefore widely used. However, since the short fibers and hot wires taken from the roller surface accumulate on the rod-shaped clarifier, which has a relatively small diameter, it is necessary to periodically clean the rod-shaped clara, which is time-consuming. Therefore, recently, a method has been used in which a blow cleaner is installed above the draft device and the draft device is cleaned by blowing air, which is useful for saving labor.

However, since the blow cleaner blows air from above the draft device, it is not possible to clean a roller that is located below the draft device and has grooves, such as a back pot roller. In particular, back pot mulola has a tendency for short fibers and immature cotton to become clogged in the grooves, and the clogged short fibers and immature fibers cannot be removed by air blowing. Therefore, even now, rod-shaped Kuryara is usually used for back pot Murora. However, when a rod-shaped clearer is used as a back pot roller, various drawbacks occur.

In other words, first of all, in terms of quality, short fibers and immature fibers adhere strongly to the grooves, and immature cotton in particular is sticky, so in the case of rod-shaped Kuryara, which is rotated by contacting the surface of the back bottom roller, the Kuryara portion The roller rotates passively with respect to the roller surface, and the surface speed is almost the same, which has the disadvantage that sufficient cleaning cannot be performed. 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 clarifier every short operating time to prevent short fibers and immature fibers from adhering to the grooves from becoming impossible to remove with the rod-shaped clarifier. This has the disadvantage of being contrary to labor saving. Furthermore, when a blow cleaner is used in the draft device, the rod-shaped cleaner for the back pot roller that is passed between adjacent roller stands acts as a barrier to the passage of air blown from above, 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 back bottom loaf, it is difficult to completely remove short fibers and immature fibers attached to the grooves of the roller. Not yet reached. The present invention eliminates the drawbacks of the cleaning device for backpot uneven rollers, has a high ability to remove short fibers and immature wires from backpot uneven rollers, and can significantly lengthen the cleaning cycle. It is an object of the present invention to provide a clearer device that can improve the usage efficiency of a blow cleaner.

A fixed clearer device for a mill loom configured to clean the back bottom roller of a spinning frame every staff between adjacent roller stands, the fixed clearer device cleaning the back bottom roller of a drafting device between the back roller and the middle roller. A roving bar disposed below the traveling roving and parallel to the rollers between adjacent roller stands, and a flat plate member detachably attached to the roller recesses of the back bottom roller and the middle bottom roller, It has a hooking part with the back roller at its tip on the back roller side, at least two roving bar support members fixed to the roving bar at approximately the center thereof, and at least a part that comes into contact with the back bottom roller. a plurality of clearer members formed of a rubber-like member and attached to the roping bar at intervals so as to substantially correspond to the fluted portion of the back bottom roller, the rubber-like member of the clearer member; and an attachment portion to the roping bar, and when the fixed clearer device is attached to the draft device, the elastic rebound mechanism works to direct the rubber member toward the back bottom roller. The relative positional relationship between the stopper part of the support member, the roving bar, and the rubber member of the clearer member is determined such that the fixed clearer device is pressed against the back bottom roller and the middle bottom. This precision roller has both the guiding function of the roving running between the rollers and the cleaning function of the back bottom roller, and is characterized in that it can be specially raised together with the back bottom roller and middle bottom roller from the roller stand of the drafting device of the spinning machine. This is accomplished by a fixed clearer device for spinning machines. The clearer member may be formed of a hollow cylindrical rubber-like member, and the rubber-like member may be fixed to the low-visig bar so that a part of the outer circumferential surface of the rubber member comes into contact with a back pot roller of the drafting device.

In this case, since the hollow cylindrical rubber member has a repulsion force against compression from the outer peripheral surface, the repulsion force acts as the repulsion force of the elastic repulsion mechanism. Note that the hollow cylindrical rubber member is fixed to the roving bar through a Kuryala member fixing bar which is inserted into a hollow hole in the rubber member parallel to the roving bar and removably fixed to the roping bar. You may go.

By fixing the roping bar of the hollow cylindrical rubber member in this way, when the fixed clearer device of the present invention is removed from the draft device for cleaning, the portion of the rubber member that contacts the back pot roller can be fixed. It can be repositioned and fixed to the roping bar again. By shifting the supporting portion, 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 Kuryara section is formed of an arc-shaped leaf spring with a rubber-like member attached to the outside of one end thereof, and the leaf spring is connected to the mounting part in another manner.
The rubber member may be removably fixed to the roving bar so as to contact the back pot roller of the draft device. In this case, the anti-trailing force of the leaf spring acts as the elastic anti-trailing mechanism. Furthermore, the length of the roving bar is set to be longer than the distance between the roller stands on both sides,
On the other hand, a groove in which the end of the roving bar engages is provided inside the corresponding roller stand, and when the fixed clearer device is attached to the draft device, the elastic rebound mechanism of the clearer member works to prevent the rubber The relative positional relationship between the hook part of the support member, the roving bar, the rubber member of the clearer member, and the groove of the roller stand may be determined so that the shaped member is pressed against the back pot roller.

In this way, when a plurality of clearer members are attached to a roving bar that is elongated in the longitudinal direction than its cross section, the relative positional relationship can be maintained approximately equal for each clearer member, and as a result, the rubber-like It helps to make the pressing force of Bemura's back pot Murora almost the same. 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 L-shaped, 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 roping bar 2.

The length in the longitudinal direction of the clearer member 1 is approximately equal to or slightly shorter than the length of the fluted portion 16 of the back pot roller 7, and the outer peripheral surface of the clearer member 1 is arranged parallel to and adjacent to the bag line direction of the back pot roller. The roving bar 2 is attached to the roving bar 2 in accordance with the position of the IJ fused portion 16 between the roller stands. The number of clearer members 1 corresponds to the number of fluidized parts 16, and is usually 4 or 8. In this embodiment, the roving bar 2 of the clearer member 1 is attached by a clearer member fixing bar 3. That is, as shown in FIGS. 2 and 4, a long and narrow cross-sectionally flat-plate fixing bar 3 is inserted into the hollow holes of the plurality of crura members 1, and the cruriara member is sandwiched between the roping bar 2 and the roving bar. -2 with a plurality of screws 12. In this embodiment, since it is easy to attach the clearer member 1 to the roving bar 2 as described above, it is easy to replace the clearer member 1 whose outer peripheral surface has been worn due to contact with the back pot roller 7, and 12 and floating the clearer member fixing bar 3, the outer circumferential surface of the clearer member 1 can be sequentially shifted and applied to the back pot roller 7. Therefore, the entire outer peripheral surface of one hollow cylindrical clearer member 1 can be used as a supporting surface for the back pot roller 7, so that the life of the clearer member 1 can be extended. As shown in FIGS. 1, 2, 3 and 4, roping bar support villages 5 are fixed to the roving bar 2 near both ends thereof at right angles to the longitudinal direction of the roping bar 2.

The support member 5 is set to a length that allows the support member 5 to be placed between the back pot roller 7 and the middle pot roller 8, as shown in FIG. The tip of the support member 5 on the side of the back pot roller 7 is bent at a right angle, as shown in FIGS. 2 and 4, and serves as a hook 4 for the back pot roller 7. The support member 5 is remounted on the smooth roller portion 9 (hereinafter referred to as roller recess 9) between the adjacent fluted portions 16 of the back pot roller 7 and the roller recess of the middle pot roller 8. At this time, the positions of the support member 5 and the roving bar 2 are determined by the stop portion 4 in the roving advancing direction of the draft device. Abrasion of the support member 5 due to contact with the roller recess 9 is prevented by pasting ingro sheet materials 6a, 6b, 6c on the contact surface with the back pot roller 7 and the middle pot roller 8 inside the support member 5. be able to. Note that the shape of the hook portion 4 of the support member 5 may be formed into an arc shape along the outer diameter of the roller recess of the back pot roller 7. FIG. 5 shows a sectional view of a drafting device of a conventional paper milling machine.

The draft device shown in FIG. 5 has a bar-shaped clearing collar 11b attached to a back pot clearing collar 12, and is further provided with a roving bar 2 for guiding the middle bottom loaf roving from the back bottom roller 12. Therefore, the air blown from the blowing collar (not shown) indicated by the arrow 17 is blocked by the rod-shaped clearing collar 11b, and is difficult to flow downward into the draft device. FIG. 6 shows a sectional view of a draft device to which a fixed clearer device according to an embodiment of the present invention is attached. As can be seen in FIG. 6, the fixed clearer device is attached to the drafting device by mounting the support member 5 into the roller recess. 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. Then, the back pot roller 7 of the hollow cylindrical clearer member 1 is pressed such that the hollow cylindrical clearer member is pressed against the surface of the back pot roller 7 and the fixed clearer device is placed on and latched to the draft device. The fixed clearer device is assembled by determining the position of the side surface and the relative positional relationship between the hook portion 5 of the support member 4 and the roving bar 2. In the fixed clearer device of the present invention, the clearer member is pressed against the back bottom roller by determining the relative position as described above, so that the pressing force of the clearer member against the back bottom roller is transferred from the bottom roller to the roller stand. It will never reach you.
Thus, the fixed clearer device of the present invention has a roving bar 2
Since it has a clearer member, it has both a guiding function for the roving running between the back bottom roller and the middle bottom roller and a cleaning function for the back bottom roller. Furthermore, the fixed clearer device is attached to the draft device by placing the support member 5 on the roller recess, so when lifting the bottom roller during regular cleaning of the spinning machine, the fixed clearer device can be removed from the roller stand together with the bottom roller. can be raised. This means that when cleaning or repairing the bearing portion of the roller stand, there are no obstacles near the roller stand, making the work easier. FIG. 7 shows an enlarged view of the relationship between the clearer member 1 and the back pot roller 7 when a fixed clearer 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 a hollow cylindrical synthetic rubber, it has an elastic repulsion force as a rubber material as well as an elastic repulsion force due to the shape of the hollow cylindrical synthetic rubber. As shown in an exaggerated manner in FIG. 7, the clearer device of the present invention connects the clearer member 1 to the back pot roller 7.
Attach by pressing it onto the fluted part 16 of. Therefore, the hollow cylindrical clearer member 1 contacts the fluted portion in a shape slightly crushed from a perfect circle, and as a result, the surface of the clearer member 1 bites into the grooves of the fluted portion 16. 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 clearer member 1 is fixed to the draft device and the back pot roller 7 is rotating, the rubber part of the clearer member removes short fibers and immature wires accumulated in the grooves of the fluted part 16. Complete removal can be achieved by digging into the particles and scraping them off. It is inconvenient if the pressing force of the clearer member 1 to the back pot uneven roller 7 is too strong or too weak.

That is, if it is too strong, an extra load will be applied to the rotation of the back pot roller 7, and the contact surface of the clearer member 1 to the back pot roller 7 will be worn more quickly.
If it is too weak, the ability to remove short fibers and immature wires will be reduced.
Therefore, in order to obtain an appropriate pressure that is useful for increasing the removal ability, the material of the clearer member 1 is taken into consideration.
The relative positional relationship between the locking part 4 of the support member 5, the o-bing bar 2, and the clearing section 1 is determined. Note that if the surface of the hollow cylindrical rubber-like member in this embodiment is given a wavy shape by special processing, the ability to remove short fibers and immature cotton from the grooves of the back pot roller can be further enhanced. In the fixed clearer device of the present invention, FIGS.
As shown in the figure, clearer members 1 are arranged on a roving rod 2 at intervals.

As a result, the fixed clearer device of the present invention does not obstruct the passage of air blown by the flow cleaner, unlike conventionally used rod-shaped clearers. When the fixed clearer device of the present invention is used, the frequency of cleaning the clearer member 1 can be greatly reduced.

That is, since the fixed clarifier device of the present invention has a structure in which the rubber member in the pressed state is applied to the grooves of the back pot roller 7 as described above, short fibers and immature cotton can be scraped off from the grooves. It is from. Therefore, unlike the rod-shaped kuriara, which collects almost all of the removed short fibers and unripe cotton on its outer surface, significantly fewer short fibers and unripe fibers accumulate on the surface of the kuriara member 1. As a result, the cleaning cycle of the clearer member 1 is significantly extended, for example, to about once every two months. In other words, it is sufficient to clean the Kuryara member 1 at the same time as the regular cleaning of the kasu loom, which is normally done once every two months. FIG. 8 shows another embodiment of the present invention.

The clear spring in this embodiment is formed of an arcuate plate spring, with a rubber member 21 attached to the outside of one end thereof, and a mounting portion 22 to the roving bar 2 provided at the other end. The rubber member 21 is pressed against the back pot roller 7 by the elastic reaction force of the leaf spring. The cross section of the attachment portion 22 is U-shaped, so that the clearer member 1 can be attached to and detached from the roving bar 2. The rest of the configuration of this embodiment is the same as that of the previous embodiment, so that the same effects as those of the previous embodiment can be obtained. FIG. 9 shows still another embodiment of the present invention.

In this embodiment, the length of the roving bar 2 is extended to cover the roller stands 13a, 13b on both sides, and protrusions 15a, 15b are provided at the tips of both sides. On the other hand, the roller stands 13a and 13b are provided with registers 14a and 14b for mounting the roving bar 2. By fixing the roving bar 1 on both sides in this way and further hooking the crab stopper part 4 of the support member 5 to the back pot roller 7, the position of the rubber member of the clearer member 1 relative to the back pot roller 7 can be adjusted to each clearer member. Therefore, the pressing force can be made approximately equal for each clearer member. Since the fixed clearer device of the present invention is constructed as described above, it is possible to improve the ability of the back pot roller to remove short fibers and immature wires.

In addition, the cleaning cycle becomes significantly longer, which helps save labor. Furthermore, there is no obstruction to the passage of air blown by the blow cleaner, thereby increasing the usage efficiency of the blow cleaner. In addition, in the fixed clearer device of the present invention, the roving bar and the plurality of clearer members arranged between adjacent roller stands can be assembled together and removably attached to the draft device, making it easy to manage them. It has the advantage of being cheap to produce.
