Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a clear cloth of a draft device in a spinning machine.

[0002]

2. Description of the Related Art Generally, in a roving machine, cleaning of a roller group of a draft device is carried out by a top clearer cloth and a bottom clearer cloth which are rotated in contact with an upper roller group and a lower roller group, respectively. And
To clean both clear cloths themselves, a method of scraping the adhering fibers from the clear cloths by a scraper (scraping member) that contacts the clear cloths is adopted.

The fibers scraped from the bottom clearer cloth fall on the roller beam on which the roller stand is supported, and by the air flow blown toward the rear part of the roller beam from the blowing part provided at the front end of the flyer rail. , Conveyed to a suction duct or a belt conveyor arranged behind the draft device and removed (for example,
JP-A-62-53429, Japanese Utility Model Laid-Open No. 14247
No. 4).

On the other hand, the fibers (cotton dust) scraped off from the top clear cloth are manually removed by a worker through a window provided in the cover above the clear cloth or removed by a cleaner. As a cleaner, Shokai 5
As in the device disclosed in Japanese Patent Publication No. 7-59878, a suction pipe having an intake opening that is opened immediately above the top clearer cloth is connected to a suction duct provided at the rear of the draft device to intermittently suck the suction pipe. There is a device that sucks and removes cotton dust by communicating with a duct.
Further, Japanese Patent Application Laid-Open No. 62-53429 discloses an automatic pipe changer that moves along the longitudinal direction of a spinning machine and is equipped with a suction pipe for sucking the cotton dust.

[0005]

However, in the conventional device, the scraping member scrapes the fibers adsorbed on the top clear cloth from the top clear cloth, and the scraped fibers accumulated on the top clear cloth are manually or sucked. Collect intermittently with a pipe. Therefore, in the case of a raw material that generates a large amount of short fibers (hereinafter simply referred to as cotton dust) adsorbed on the top clear lacrosse, the amount of cotton dust scraped off from the top clear lacrosse should be collected before the time comes to collect the cotton dust. There is a case where it exceeds the accommodation space. And a part of the cotton dust gets over the partition wall of the storage space and falls,
It may enter the spun yarn and deteriorate the quality of the spun yarn. In addition, there is a problem that simply scraping the cotton dust off the top clear cloth is bulky and the collection work is difficult.

On the other hand, the fibers scraped off from the bottom clear cloth often hang down in a strip shape from the vicinity of the tip of the scraping member, and the fibers hung down in a strip shape are blown toward the rear part of the roller beam from its own weight or the blowing portion. Due to the generated air flow and the suction action of the suction duct, it shreds and falls. In this way, the fibers that hang down in the form of strips or the fibers that have been cut and dropped are difficult to convey to the suction duct or the belt conveyor. In the device provided with the suction duct, the belt-shaped fibers can be surely sucked by increasing the negative pressure, but there is a problem that the power consumption which is originally large compared with the belt conveyor is further increased. Also, in the device equipped with a belt conveyor, compared to the device equipped with a suction duct, the time in which the belt-shaped fibers hang down is longer, and the cleaning operation is performed by blowing air while moving along the spinning machine stand. There is a high possibility that the fibers will be scattered by the air flow blown from the so-called traveling cleaner.

The present invention has been made in view of the above problems, and its first object is to make it possible to prolong the recovery period of the fibers (cotton dust) scraped from the top clear lacrosse, An object of the present invention is to provide a cleaning device for clear lacross in a spinning machine, which can facilitate the recovery of fibers.

Scrap from top clear lacrosse. When the scraping member moves to the tip side, the cotton dust scraped from the top clearer cloth is sandwiched between at least one of the scraping member and the top clearer cloth and the compression member, and is pressurized. Then, the cotton dust is temporarily stored in the storage unit in a compressed state. Since the cotton dust is stored in the storage portion in a compressed state, the volume is small even with the same weight, and it takes a long time to reach the amount exceeding the storage space of the storage portion. Further, the compression eliminates the fluffy and bulky state, which facilitates the recovery work.

According to the second aspect of the present invention, the bottom clearer cloth disposed below the bottom roller of the draft device orbits in a predetermined direction while a part of the bottom clearer cloth is in contact with the bottom roller, and adheres to the bottom roller.

Scrap from bottom clear lacrosse. When the scraping member moves to the tip side, the cotton dust scraped from the bottom clearer cloth is sandwiched between at least one of the scraping member and the bottom clearer cloth and the compression member and is pressurized. Then, the cotton dust falls in a compressed state. Since the scraped cotton dust is compressed, unlike the conventional device, it does not hang down in a strip shape for a long time. Further, the cotton dust scraped off becomes a relatively short caterpillar-like fiber mass due to the compression action and falls on the roller beam. Then, it is smoothly guided to a belt conveyor or a suction duct arranged behind the draft device.

According to the fourth aspect of the present invention, the cotton dust scraped off the top clearer cloth by the scraping member is between the roller and the top clearing cloth or the roller when the scraping member moves to the tip side thereof. It is clamped between the scraping member and the scraping member and compressed. When the scraping member moves toward the tip end side, a force is applied to the roller in a direction opposite to the direction in which the roller is rotated together with the top clearer cloth, so that the effect of twisting cotton dust is enhanced.

According to the fifth aspect of the invention, since each compression member is made of a flexible plate material, the structure is simple. In the invention described in claim 6, when the cotton dust scraped off from each clear cloth is accumulated to some extent between the compression member and the clear cloth, when the scraping member moves to the opposite side to the scraping direction. , Is moved from the holding state between the compression member and the clear cloth and is compressed to the storage section or is dropped.

The pressing roller 37 is integrally rotatable with a shaft 38 common to the four weights, and as shown in FIG. 3, the shaft 38 is vertically moved along a groove 39a formed in a guide bracket 39 fixed to both side walls 21b. It is movably supported. That is, the pressing roller 37 is rotatably arranged at a predetermined position while being pressed toward the top clearer cloth 7 side by its own weight and the weight of the shaft 38. The arrangement position of the pressing roller 37 is set apart from the partition wall 24, and the scraper 34 is set to a position where it can enter between the pressing roller 37 and the top clearer cloth 7.

As shown in FIGS. 4 and 5, the scraper 9
Is formed into an L shape on the side surface, and the scraping portion 9a has a sawtooth-shaped tip.
A hole 9b through which the bolt 40a is inserted, and a pair of holes 9c through which the screw 40b is inserted. Scraper 9

A plate member 42 as a compression member for the bottom clearer cloth is fixed to the scraper 9 so as to be integrally movable. The plate member 42 is substantially L-shaped, and has a width equal to that of the scraper 9 and is formed of a rigid body so that its tip extends longer than the tip of the scraper 9. The width of the plate member 42 is formed so that the bottom clearer cloth 6 for four weights can be cleaned. Then, the plate member 42 is integrated with the scraper 9 by the screw 40b, the washer 43 and the cap nut 41b in a state of having a gap δ with the bottom clearer cloth 6 (a state of contacting the lower surface of the scraper 9 in this embodiment). It is movably fixed. The gap δ between the support plate 42 and the bottom clearer cloth 6 is preferably several mm or less, but the scraping portion 9
It may be about 10 mm depending on the length of the portion extending longer than a.

A belt conveyor 44 is provided at the rear side of the roller beam 1 in the longitudinal direction of the roving machine stand (direction orthogonal to the plane of the drawing).
Has been extended along. Also, flyer rail 45
At the front end (only a part is shown), the cover 45a of the flyer rail 45 and the upper surface of the roller beam 1 are attached to the belt conveyor 4
A blower tube (not shown) is provided to blow out an air flow flowing toward the 4 side.

Next, the operation of the device configured as described above will be described. When the operation of the roving machine is started, the sliver S is supplied to the draft device 2 for drafting,
It is wound up on a bobbin (neither is shown) via a flyer. Further, the eccentric cam 12 is rotationally driven in a fixed direction, and the bottom clearer cloth 6 is intermittently rotated in the arrow direction in FIG. 1 together with the rotary shaft 17 and the pulley 16 via the link 15 by the swing motion of the cam lever 13. . Also,
The support bracket 30 is moved by the swing motion of the cam lever 13,
The rotary shaft 2 is connected via the connecting rod 31 and the ratchet lever 29.
The top clearer cloth 7 is intermittently rotated together with 8 and the pulley 18 in the direction of the arrow in FIG. When the sliver S is drafted by the draft device 2, a small amount of short fibers (cotton dust) is generated by the bottom rollers 4a to 4d and the top rollers 5a to.
Adhere to 5d. The dust collected on the bottom rollers 4a to 4d is transferred to the bottom clearer cloth 6 and the top rollers 5a to 5d.
The cotton dust adhering to d is adsorbed by the top clear cloth 7 and removed from each roller.

As the cam lever 13 swings, the link 15
The scraper 9 is reciprocated in a state of abutting the bottom clearer 6 through the scraper 9, and the cotton dust adsorbed on the bottom clearer cloth 6 is scraped off by the scraper 9. The cotton dust scraped off from the bottom clearing cloth 6 is a plate material 42.
Between bottom and bottom clear lacrosse 6. The retreat of the scraper 9 (movement to the left in FIG. 1) and the movement of the bottom clearer cloth 6 are performed in synchronization, but the amount of movement of the support 10 is larger than the amount of movement of the bottom clearer cloth 6. Therefore, when the cotton dust is accumulated to some extent, a part of the cotton dust held between the plate member 42 and the bottom clearer cloth 6 is compressed while rotating when the scraper 9 retracts. Then, it becomes a caterpillar-like fiber mass F that escapes from the tip of the plate material 42 and falls onto the roller beam 1, and is blown from the front end portion of the flyer rail 45 toward the rear portion of the roller beam 1 by the roller. It is conveyed and removed by a belt conveyor 44 disposed behind the beam 1.

If the plate member 42 is not present, the cotton dust scraped off the bottom clearer cloth 6 by the scraper 9 tends to hang down in the form of a band. However, when the plate member 42 is present, the cotton dust scraped off as described above is held on the plate member 42 until it reaches a certain amount, and then becomes the worm-like compressed fiber mass F on the roller beam 1. To fall.
Further, the weight of each caterpillar-like fiber mass F becomes lighter than the weight of the strip-shaped long-hanging cotton dust, and the fiber mass F dropped on the roller beam 1 is conveyed by the belt conveyor 44.
Even if the air flow toward the side is not so strong, it is smoothly conveyed to the belt conveyor 44.

Further, as the cam lever 13 swings, the scraper 34 is reciprocated in a state of contacting the top clearer cloth 7 via the support bracket 30, the connecting rod 31, the ratchet lever 29 and the support member 32. Scraper 3
4 moves to the side opposite to the moving direction of the top clearing cloth 7 (right side in FIGS. 1 and 2) when the supporting member 32 moves forward (forward)
Then, when returning, it moves (retracts) to the same side as the moving direction of the top clearing cloth 7. The scraper 34 is held in a state where the tip thereof is pressed against the top clearer cloth 7 with an appropriate pressing force by the bolt 36, and the cotton dust adsorbed on the top clearer cloth 7 moves forward of the scraper 34, that is, The scraper 34 is scraped off when it moves to the tip side. The scraper 34 advances to a position beyond the contact portion between the pressing roller 37 and the top clearer cloth 7. Therefore, the cotton dust scraped from the top clearing cloth 7 is pushed by the pressing roller 37 when the scraper 34 moves forward.
And is compressed between the pressing roller 37 and the top clearer cloth 7 or between the scraper 34 and the pressing roller 37. The cotton dust is twisted as it passes through the pressing position of the pressing roller 37 in a compressed state to form a caterpillar-like fiber mass F, and is stored in the storage unit 25 in a state where its volume is reduced. The cotton dust stored in the storage portion 25 is regularly collected and removed by a cleaner or manual work.

This embodiment has the following effects. (A) The cotton dust scraped off from the bottom clearer cloth 6 by the scraper 9 is compressed by the action of the plate member 42 (compressing member) to become a caterpillar-like fiber mass F, and then falls. Is lighter than cotton dust that hangs down from the tip of the scraper 9 in a strip shape and then breaks into pieces. Therefore, the fiber mass F dropped on the roller beam 1 is fed from the front end of the flyer rail 45 to the roller beam 1.
Even if the air flow blown toward the rear part is not so strong, it is smoothly conveyed to the rear of the roller beam 1. Therefore, even if the belt conveyor 44, which consumes less power than the suction duct, is used as a device for transporting and removing the cotton dust scraped off from the bottom clearer cloth 6, it can be reliably transported and removed.

(B) The cotton dust scraped from the top clearer cloth 7 by the scraper 34 becomes a caterpillar-like fiber mass F by the action of the scraper 34 and the pressing roller 37 or the top clearer cloth 7 and the pressing roller 37. Its volume becomes smaller. Therefore, compared to the conventional case, it takes a longer time until the amount of cotton dust scraped from the top clearer cloth 7 exceeds the storage space of the storage section 25.
As a result, even when a raw material that generates a large amount of cotton dust is used, the cotton dust scraped from the top clear lacross 7 does not overflow from the storage portion 25 during the collection cycle. In addition, the collection cycle of cotton dust can be made longer than before, and the labor of the operator when manually collecting is reduced.

(C) Cotton dust is compressed by the pressing roller 37 rotatably supported, and the pressing roller 37
When the scraper 34 moves forward along with the cotton dust, a force is applied in a direction opposite to the direction in which the scraper 34 rotates along with the top clearer cloth 7, so that the effect of twisting the cotton dust is enhanced.

(D) When the cotton dust stored in the storage portion 25 is fluffy and bulky, when the cotton dust is collected by a suction pipe or the like, the cotton dust is likely to be clogged in the middle of the suction pipe, which makes the collection work difficult. However, the cotton dust scraped off from the top clear lacross 7 is temporarily stored in the storage portion 25 in a compressed state, which facilitates the recovery work.

(E) Since the pressing roller 37 is movably supported in the vertical direction, when the scraper 34 enters the lower side of the pressing roller 37, the scraper 34, the top clearer cloth 7 and the pressing roller 37 cannot be forced. It is possible to prevent excessive force from being applied.

(F) The plate member 42 is clamped and fixed to the support 10 in a state of being in contact with the lower surface of the scraper 9, and the plate member 4
2, the bottom clearer cloth 6 and the gap δ are determined by the thickness of the scraper 9. Therefore, by using the scraper 9 having a predetermined thickness, it becomes unnecessary to adjust the gap δ between the plate member 42 and the bottom clearer cloth 6.

(Second Embodiment) Next, a second embodiment will be described with reference to FIGS. 6 and 7. In this embodiment, a flexible plate member 46 is used instead of the pressing roller 37 as the compression member for the top clearer cloth, which is different from the above embodiment, and the other configurations are the same.
The same parts are denoted by the same reference numerals, and detailed description is omitted.

A nylon plate is used as the plate member 46, and the base end of the plate member 46 is fixed to the partition wall 24. Plate material 46
Has a tip extending to a position above the tip of the scraper 34, a substantially central portion thereof abutting the top clearer cloth 7, and a side facing the scraper 34 is bent and formed so as to have a wide distance from the top clearer cloth 7.
As shown in FIG. 7, the plate material 46 is the top clear lacross 7
The opening 46a is formed to be wider and has a width substantially equal to that of the top clearer cloth 7 near the partition wall 24. The opening 46a is formed closer to the partition wall 24 than the position where the tip of the scraper 34 reaches when the scraper 34 moves to the most advanced position.

In this embodiment, the cotton dust scraped off from the top clearer cloth 7 when the scraper 34 is moved forward,
As the scraper 34 moves, the scraper 34 is moved to the partition wall 24 side, and is sequentially pushed between the plate member 46 and the top clear lacross 7. Then, while being pressed by the plate member 46, it is gradually moved to the opening 46a side, and when it moves to a position corresponding to the opening 46a, it is stored on the plate member 46 through the opening 46a.

Also in the case of this embodiment, the cotton dust scraped off from the top clearer cloth 7 moves while being pressed by the plate member 46 and becomes twisted into a caterpillar. Therefore, the collection cycle of the cotton dust stored in the storage section 25 can be lengthened as in the above-described embodiment, and the collection work can be facilitated. Further, in this embodiment, since the flat plate member 46 is used as the compression member for top clearer cloth, the structure and attachment of the compression member for top clearer cloth are easier than in the case of using the pressing roller 37. And the cost will be lower.

The present invention is not limited to the above-described embodiments, but may be embodied as follows. (1) The pressing roller 37 is simply placed on the top clearing cloth 7 at a position corresponding to the storage portion 25. Then, as shown in FIG. 8, a restricting piece 47 is provided on the partition wall 24 so as to prevent the pressing roller 37 from rolling in the moving direction of the scraper 34 when the scraper 34 moves forward. After the pressing roller 37 comes into contact with the restricting piece 47, the pressing roller 37 is restricted from rolling toward the partition wall 24 even if the scraper 34 moves forward, and is rotated at the position where it comes into contact with the restricting piece 47. . Then, the cotton dust scraped off from the top clear lacross 7 is compressed in the same manner as in the first embodiment. In this case, the configuration is simpler than that of the first embodiment.

(2) As the top clearer cloth compression member, a roller may be rotatably provided at a predetermined position slightly apart from the top clearer cloth 7. (3) As shown in FIG. 9, the plate member 46 is attached to the bracket 35.
May be attached to the upper surface of. The cotton dust scraped off from the top clear cloth 7 collects between the plate member 46 and the scraper 34 or the top clear cloth 7. Scraper 3
4 and the movement of the top clear lacross 7 are performed in synchronization with each other, but the distance from the rotation shaft 28 to the connecting position of the support member 32 to the ratchet lever 29 is larger than the radius of the ratchet wheel, so that the support member 32 moves. The amount is larger than the amount of movement of Top Clear Lacrosse 7. Therefore, when the dust is collected to some extent, the plate member 46 is moved when the scraper 34 retracts.
Part of the cotton dust retained between the top clearing cloth 7 and the top clearing cloth 7 rotates and escapes from the tip of the plate member 46. Even with this configuration, the cotton dust is compressed into a caterpillar-like fiber mass F and stored in the storage portion 25. In this case, the plate member 46 can be easily attached.

(4) Instead of providing the bottom clearer cloth compression member so as to be movable integrally with the scraper 9, it may be fixed at a predetermined position. For example, as shown in FIG.
A support piece 48a is provided on a support beam 48 that supports a guide member 6a for the bottom clearer cloth 6, and the support piece 4a is provided.
A flat plate member 42 is fixed to 8a. It is preferable to fix the plate member 42 so that the gap δ with the bottom clearer cloth 6 becomes narrower as it goes away from the scraper 9. Also in this case, after the cotton dust scraped off from the bottom clearer cloth 6 is accumulated on the plate material 42 to some extent, it is twisted while being compressed by the action of the scraper 9 to form a caterpillar-like fiber mass F.

(5) Support 1 for supporting scraper 9
As a configuration for supporting 0 to be movable back and forth, instead of supporting it through a pin 11 on a bracket 8 having an elongated hole 8a,
As shown in FIG. 10, the support rod 50 is fixed to the support bracket 49 protruding from the support beam 48. Then, the tip end side of the support body 10 is extended to the front of the fixed portion of the scraper 9, and the extension portion 10b is placed on the support rod 50.
In this configuration, the extension portion 10b of the support body 10 slides on the support rod 50 as the link 15 swings.

(6) A plate material 42 made of a nylon plate, which is a flexible material, is used as the compression member for the bottom clearer cloth, and the plate material is the same as the plate material 46 for the top clearer cloth of the second embodiment. An opening (not shown) is formed at 42. As shown in FIG. 11, the plate member 42 has its base end side in contact with the bottom clearer cloth 6 and its tip extends below the tip of the scraper 9,
The support beam 48 is bent and formed so as to have a portion extending parallel to the lower surface of the scraper 9 through the support piece 48b.
It is fixed to. When the scraper 9 moves to the most advanced position, the plate member 42 is formed with an opening having the same width as the bottom clearer cloth 6 on the base side from the contact portion with the bottom clearer cloth 6 on the base side from the position reached by the tip of the scraper 9. Has been done. The cotton dust accumulated on the plate member 42 moves between the bottom clearer cloth 6 and the plate member 42 while being pressed by the plate member 42 when the scraper 9 is compressed, and becomes a caterpillar-like fiber mass F to open. To fall from. In this case, even if the amount of cotton dust accumulated on the plate member 42 is small, the cotton dust is likely to be caterpillar-like due to the action of the scraper 9, the bottom clearer cloth 6 and the plate member 42.

(7) As shown in FIG. 12, a guide plate 51 is provided for guiding the fiber mass F falling below the plate member 42 onto the belt conveyor 44 disposed behind the roller beam 1. In this case, even if there is no air flow blown from the front end of the flyer rail 45 toward the rear of the roller beam 1, the fiber mass F is guided onto the belt conveyor 44 arranged behind the roller beam 1. It is conveyed and removed by the belt conveyor 44. When a suction duct is provided instead of the belt conveyor 44, the fiber mass F (cotton dust) can be smoothly transported and removed even if the suction action of the suction duct is small.

(8) The material of the flexible plate members 42 and 46 is not limited to nylon, and other resin, spring steel or the like may be used. Further, when the compression member is a resin plate or sheet, the compression member can be manufactured at low cost.

(9) The bolt 36 may be omitted and the scraper 34 and the bracket 35 may be pressed against the top clearer cloth 7 by their own weight. (10) Instead of using four support members 32 in common, each support member 32 may be provided for each top clearing cloth 7 or two support members may be used in common. In that case, the shape of the support member 32 is set so as not to interfere with the pressing roller 37. (11) The shapes of the scrapers 9 and 34 may be appropriately changed. For example, the scraping portion 9a of the scraper 9 for the bottom clearer cloth 6 may have the same flat blade shape as the scraper 34 instead of the saw blade shape, or the scraper 9 may have a flat plate shape and be fixed to the upper surface of the L-shaped plate member 42. May be. Further, the plate member 42 on the bottom side may be directly fixed to the lower surface of the scraper 9 on the bottom side.
