Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a cleaning device for a roller part in a roving machine, and in particular, a blower tube that gives a blown air flow to the roller part, and an intake tube that opens at the rear end of the roller beam. Regarding those with.

2. Description of the Related Art The above technique is disclosed in, for example, Japanese Patent Laid-Open No. 61-174433. According to this, the jet air flow is blown toward the roller part from the hollow clear guide bar (blown air pipe) of the top clearer arranged above the roller part, and the cotton wool in each part of the roller part is blown off to drop the roller beam. It is shown that this cotton wool is collected from an intake pipe that opens at the rear end.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to the above, as the blown air of the roller part is positively blown off by the jet of air, the blown ball accumulation on the roller part is reduced. By the way, above the roller part, there is a top cover of the top amen's squirrel. This top cover is shaped to cover the front upper part of the front roller of the roller part and the rear end upper part of the top clearer cloth, and it is located between the front end upper surface of the roller beam and the front surface of the top cover and the opening upper edge of the intake pipe Since it is widely opened to the rear end of the cover, some of the fly flies blown off as described above may fly up and scatter from these open parts to contaminate the factory. . In addition, there was also a cotton fly invasion from these open parts.

An object of the present invention is to provide a roller part cleaning device including a blower pipe and an intake pipe, which can prevent the above-described fly dust scattering and can prevent the fly dust from entering from the outside. .

Means for Solving the Problems In order to solve the above problems, according to the present invention, a roller part is actively cleaned by blowing air to blow off cotton dust and then collected from an intake pipe. On the front side of the top cover of the top amens rear cover, which covers the rear top edge of the top clearer cloth from the front upper part, the top edge of the front cover that covers the top surface of the roller beam is attached to the front cover while swinging freely. A roving thread passing groove with an open lower end is provided, and a fixed cover is provided between the upper edge of the intake pipe and the rear end of the top cover, and the fixed cover hinges to open and close following the swing of the top cover. The cover is covered with a rear cover including a movable cover, and a sliver passage hole is provided in the fixed cover in correspondence with the roving passage groove.

Action According to the above, since the entire roller part is almost completely covered except for the sliver passage hole and the roving yarn passage groove, a part of the cotton wool of the roller part is blown by the air flow blown from the blower pipe inside the roller part. Even if it goes up, it does not scatter from the roller part to the outside, improving the efficiency of collecting cotton wool from the intake pipe and preventing the inside of the factory from being polluted. It also prevents the invasion of cotton fly from the outside. Furthermore, in the case of roving breakage, the front cover can be swung upward to maintain this state, and when the entire top amen screeler is swung, the movable cover of the rear cover follows it. To rock.

Embodiments In FIGS. 1 and 2, the roller part 1 for four weights of one stuff is composed of bottom rollers 4a to 4d supported on roller stands 3 and 3 on the roller beam 2 and, by contrast, by a top arm 5. It is provided with top rollers 6a to 6d which are pressurized. A top clearer cloth 7 and an under clearer cloth 8 are arranged on the peripheral surfaces of the top rollers 6a to 6d and the bottom rollers 4a to 4d on the upper side or the lower side of the sliver passing portions so as to intermittently rotate in a pressed state. In this intermittent rotation, the follower 11 is moved back and forth and up and down by the rotation of the eccentric cam 10 which is integral with the clearer drive shaft 9, and the eccentric movement causes the connecting rod 12 to move up and down to swing the swing member 13. Then, the intermittent rotation shaft 14 rotates via the ratchet pawl feeding mechanism in the swinging member 13, and the clear lacross drive roller 15 integrated with the intermittent rotation shaft 14 is rotated. Projecting portion 1 of swing member 13
3a has one end of a connecting plate 16 pin-connected,
The connecting plate 16 moves back and forth by a predetermined amount by the rocking of the rocking member 13. A comb 17 for cleaning the clear cloth is integrally connected to an intermediate portion of the connecting plate 16. Also,
A locking hole 18 is formed at the tip of the connecting plate 16.

Top arm brackets 19 are fixedly attached to the rear portions of the left and right roller stands 3.
Top amen's rear frame 20 of each top amen's rear is pivotally supported by a pin 21. A support shaft 22 is provided at the tip of the top armen screeler frame 20 so as to project inward. The support shaft 22 rotatably supports the end of the air blow pipe 23. The end of the blow tube 23 is closed by a side plate 24, and the blow tube 23 has a large number of blow openings 25 which are open downward in FIG. The longitudinal position of the air outlet 25 is
It is set at a position facing the end portions 26, 27 of each roller of the roller part 1 so that the compressed air is not directly blown toward the sliver. At the lower center of the blow tube 23, the engaging pin 2
8 is projectingly provided at a position rotated by a predetermined angle clockwise with respect to the air outlet, and is engaged with a locking hole 18 of the connecting plate 16. A flexible supply pipe 23a made of a rubber material or the like, which is connected to a compressed air source (not shown), is connected to the air blow pipe 23 through the hole of the top amen screeler frame 20. Therefore, during operation of the machine base, the connecting plate 1
The forward and backward movement of 6 causes the blow tube 23 to swing about the support shaft 22 by a predetermined angle, whereby the air flow discharged from the blow outlet 25 is periodically diverted within the range A in FIG.

A top cover 31 is integrally mounted above the roller part 1 between the left and right top armen screeler frames 20. The top cover 31 has an L-shaped cross section from the front edge of the top amens clearer frame body 20 to the rear portion of the top edge so as to cover the top clearer cloth 7. On the front surface of the top cover 31, an upper end of a front cover 32 made of a transparent acrylic material is hinged by a hinge 33. As shown in FIG. 1, the front cover 32 has a roving passage groove 34 that opens downwardly corresponding to the roving R spun from the roller part 1, and the left and right end portions of the front cover 32 are formed. An intermediate portion except 32a is bent rearward so that an air intake 35 is formed between the roller beam 2 and the upper surface thereof.

This air intake 35 is, for example, utility model registration No. 1466.
No. 354 or a centrifugal fan 37 at the front end of the flyer rail 36 as shown in FIG. 3 for taking in an air flow for cleaning the fly dust on the upper surface of the flyer rail cover 38. Left and right ends 3 of the front cover 32
2a is slightly bent forward, and a steel plate 30 is attached to the back surface thereof. The steel plate 30 is attracted by the magnet catcher 29 fixed to the front end of the roller stand 3,
Normally, the front cover 32 is held as shown in FIG.

A bracket 39 is fixed to the rear portion of the top arm bracket 19 as shown in FIG. 4, and an upper edge portion 40a of an intake pipe 40 facing the centrifugal fan 37 and opening at the rear end of the roller beam 2 is attached to the bracket 39. , The top cover 3
The rear cover 41 that covers the gap between the rear end portion 1 and the rear end portion 1 is screwed. The rear cover 41 is composed of a fixed cover 41a slightly above the bracket 39, and a movable cover 41b which is openably and closably connected to the fixed cover 41a via a hinge 42 provided with a torsion coil spring 42a. A guide bush 43 as a sliver S passage hole is attached to the fixed cover 41a. 44 is a front collector,
Reference numeral 45 is a condenser, 46 is a sliver guide, and 47 is an upper support type flyer.

According to this structure, the cover 32 is held by the magnet catcher 29 as shown in FIG. 2, and the tip of the movable cover 41b of the rear cover 41 is also attached to the rear end of the top cover 31 by the spring 42a of the hinge 42. The top cover 31 and these front and rear covers 3 are pressed against the upper surface.
The roller part 1 is substantially covered by the rollers 2 and 41 except for the roving passage groove 34, the air intake 35, and the guide bush 43. Therefore, the cotton wool from the outside is prevented from entering the roller part 1. In this state, the machine base is operated, and the swinging member 13 swings so that the connecting plate 16 moves back and forth by a predetermined amount to blow the blow tube 2
3 is rocked periodically. As a result, the air flow blown out from the air outlet 25 changes its direction in the front-rear direction and directly acts on the end portions of the rollers of the roller part 1, and blows the cotton wool accumulated on these portions. In addition, part of the airflow is the front collector 4
4, the condenser 45, and the sliver guide 45 are also blown off. The fly flies blown off in this way are guided downward by the air flow, and are sucked from the intake pipe 40 by the air flow blown out by the centrifugal fan 37 that has cleaned the flyer rail cover 38 on the upper surface of the roller beam 2. To be done. At this time, a part of the blown fly may fly up, but since it is covered with the front and rear covers 32 and 41, it does not scatter outside from the roller part 1 and contamination in the factory is prevented. . A part of the blown airflow becomes a flow along the inner surface of the rear cover 41 and smoothly guides the fly dust that has dropped onto the inner surface of the rear cover 41 to the intake pipe 40.

When the top armen scribing frame 20 is swung backward with the pin 21 as a fulcrum to swing the top arm 5 upward, the inner surface of the movable cover 41b slides on the rear end surface of the top cover 31. The state of the two-dot chain line in FIG. 2 is reached, and vice versa.
The spring 42a, the movable cover 41
b is restored.

Incidentally, when the roving R is cut, it is generally arranged to be spliced immediately after the front roller 4a (near FIG. 2B).
At this time, in this embodiment, the front cover 32 swings upward, so that it is sufficient to connect the front cover 32 in that state.
Even if two are provided, the work is easy.

In the present embodiment, the blowing tube is of the swing type, but the present application is not limited to this, and may be of the fixed type.

As described above, according to the device of the present invention, the roller part is positively cleaned by the blowing airflow and sucked from the intake pipe, and is almost completely removed except for the sliver passage hole and the roving yarn passage groove. Since the entire roller part is covered with the air flow, it is possible to prevent the dust from blowing out of the roller part even if it blows up from the various parts of the roller part due to the airflow, and the dust from the roller part can be reliably collected from the intake pipe. It is possible to prevent pollution in the factory. Moreover, since the cotton wool in the factory does not enter the roller part, there is an advantage that the cotton wool is not attached to the roving yarn and high quality roving yarn can be produced. Even if the roller part is almost completely covered in this way, the front cover is attached to the front surface of the top cover in a swingable manner, so that the front cover can be moved upward when the roving breaks. Even if there is such a front cover, the roving can be spliced and spliced, and the work is easy. Moreover, when the entire top amens rear sill is swung backward, this swing opens the movable cover of the rear cover, and conversely, if it is returned to the original position, the movable cover also returns to the original, so You can open and close the movable cover just by opening and closing.
