Description

TECHNICAL FIELD This invention relates to a cleaning device for a roller part in a spinning machine such as a roving machine.

2. Description of the Related Art In the spinning machine as described above, fly fluff is generated by the draft action in the roller part, and the fly fluff is deposited on members other than the fiber passing portion such as the bearing portion and the roller neck portion of the draft roller. Conventionally, various cleaning devices have been proposed in order to prevent the accumulated cotton wool from being taken into the drafted roving yarn and deteriorating the quality of the roving yarn. For example, in Japanese Unexamined Patent Publication No. 61-174433, a hollow cross guide bar (blowing tube) of a cross guide of a top clearer is provided with small holes for blowing air toward the second and front top rollers, and the sliver running surface is provided. It is disclosed that an oblique jet flow is applied.

According to the above, according to the above, the air jet flow acts obliquely on the sliver running surface, but since the jet direction is constant, the range where the jet flow directly acts is the second and front roller parts. For example, it is only in a narrow area where the small holes are directed. Therefore, a portion that the jet flow does not directly reach occurs, and cleaning cannot be said to be reliable. In order to ensure the cleaning, a plurality of air blow tubes should be provided in the sliver traveling direction, or one air blow tube should be provided with small holes with different phases in the circumferential direction without increasing the range in which the jet flow acts. must not. Then, there is a problem that a large amount of air is required and it is not economical.

An object of the present invention is to provide a roller part cleaning device capable of efficiently removing accumulated fly dust with a small amount of air.

Means for Solving the Problems In order to solve the above problems, the top clear lacross is intermittently circulated to clean the top roller, and at the upper position of the top roller, a blow tube having a plurality of blow ports in the longitudinal direction is provided. In the cleaning device for the roller part of the spinning machine, a diverting means for diverting the air flow from the air outlet of the air blow tube back and forth is provided, and the driving of the diverting means is provided with a comb for cleaning the top clear lacross. However, it is characterized in that it is also used as a connecting plate that moves back and forth.

Action According to the above, the top clearer cloth is cleaned by the forward / backward movement of the connecting plate, and the blowout airflow from the blower port of the blower tube is deflected back and forth to periodically clean the entire roller bart. Since the blowing direction of the blowing airflow is changed, it directly reaches every corner of the roller part.

Embodiments In FIGS. 1 and 2, the roller part 2 on the roller stand 1 includes bottom rollers 3a to 3d, and a top roller 5 which is pressed by a top arm 4 from above.
a to 5d. The top clearer cloth 6 and the under clearer cloth 7 are intermittently circulated in a pressure contact state on the peripheral surfaces of the bottom rollers 3a to 3d and the top rollers 5a to 5d on the upper side or the lower side of the sliver passing portion and the top roller 5a
.About.5d, the sliver passing portions of the bottom rollers 3a to 3d are cleaned. The roller part 2 includes a front collector 8, a condenser 9, and a sliver guide 10.
Are arranged.

Next, the intermittent circulation mechanism of the top clear lacross 6 will be described. A cam follower 13 is rotatably fitted on the outer periphery of the eccentric cam 12 that is integral with the clearer drive shaft 11 that rotates in one direction. One end of a connecting rod 14 is connected to the cam follower 13. Connecting rod 14
The other end of is connected to the lower end of the swinging member 15 by a pin. As shown in FIG. 2, the swinging member 15 has a U-shape, and a ratchet pawl feeding mechanism (not shown) is built in the inside. When the swinging member 15 swings back and forth by the rotation of the eccentric cam 12, the ratchet pawl feeding is performed. The ratchet wheel 16 of the mechanism is intermittently rotated in one direction. The ratchet wheel 16 is integrally connected to a top clearer cloth drive shaft 17, and a clearer cloth drive roller 18 around which the top clearer cloth 6 is wound is integrally connected to the drive shaft 17.

One end of the connecting plate 20 is pin-connected to the upper protruding portion 15 a of the swing member 15. Connection plate 20
In the middle of, a comb 21 for cleaning the clear cloth that is pressed against the top surface of each top clear cloth 6 is integrally connected. Therefore, the swing of the swing member 15 causes the connecting plate 2 to move.
0 goes around a predetermined amount. A locking hole 22 is formed in the front end portion of the connecting plate 20, and a pin 31 protruding from the lower center of a blower tube 30 described later is fitted into the locking hole 22.

Next, in the blow tube 30, a bearing shaft 34 at its end portion is rotated by a support shaft 33 projecting inward at the tips of the left and right top amens frame bodies 32 swingably supported by the roller stand 1 by pins 25. It is supported freely. The inner side of the bearing 34 of the blower tube 30 is closed by a side plate 35, and the blower tube 30 has a large number of blower openings 36 that are open toward one side in the circumferential direction and are arranged in a line in the longitudinal direction. The blower ports 36 are directed to the end portions of the rollers of the roller part so that the compressed air is not blown directly toward the sliver S. This blow tube 30
An air pipe 38 connected to the compressed air source 37, which operates with the operation of the machine base, is connected to the. The angular position of the pin 31 and the air outlet 36 in the circumferential direction at the lower part of the blow tube 30 is such that the pin 31 is rocked at the forward end (shown by the solid line in FIG. 1) when the connecting plate 20 is at the forward end. At this time, the blowout port 36 is directed toward the top roller 5a, and when the connecting plate 20 is at the retracted end, the pin 31 swings to the retracted end (first
(Shown by the chain double-dashed line in FIG. 2), and at this time, the air outlet 36
Are directed toward the top roller 5d. As described above, according to this embodiment, the left and right rotary support structures of the blow tube 30 and the connecting structure of the connecting plate 20 for rotating the blow tube 30 by a predetermined angle and the pin 31 under the blow tube 30 are different. Orientation means 40 is constructed, by means of which the air outlet 36
The air flow blown out from is deflected in the front-back direction of the roller part 2.

Top cover 5 between the left and right top Amens frames 32
1 is mounted, and a front cover 52 having a lower portion and a roving thread passing portion opened is hinged on the front surface of the top cover 51, and is attracted to the magnet 53 on the front side of the roller stand 1. A rear cover 55 that is continuous with the upper surface of the intake port 64 is fixed to the bracket 54 integrated with the left and right roller stands 1. A sliver passage hole is formed in the rear cover 55, and one end of the swing cover 56 is hinged. It is screwed and biased forward by a coil spring built in this hinge so as to come into contact with the rear portion of the upper surface of the top cover 51. Therefore, when the top Amens frame body 32 integrated with the top cover 51 is swung upward with the pin 25 as a fulcrum, the swing cover 56 is swung backward against the spring force of the hinge.

Now, when the machine base operates, the roller part 2 performs a draft action and the clearer drive shaft 11 rotates in one direction. Then, the eccentric cam 12 rotates, and the cam follower 13
Eccentrically moves, so that the connecting rod 14 moves up and down. As a result, the swinging member swings back and forth, and the connecting plate 20 also moves back and forth by a predetermined amount. This connecting plate 20
The pin 31 of the intake pipe 30 is hooked by the forward / backward movement of the intake pipe 30, and the intake pipe 30 swings by a predetermined angle. Therefore, during the operation of the machine stand, the airflow from the intake port 36, which constantly blows out, is continuously diverted within the range A shown in FIG. 1 during the operation of the roving frame, and the roller neck portions 60, 61 and the draft rollers are operated. Directly exerts an air flow on the bearing. As a result, the flies that try to adhere to these parts or that adhere to the parts are surely blown off and dropped. Further, the front collector 8, the condenser 9, and the sliver guide 10 are also covered with the blown out airflow over a wide range, and these portions are also cleaned. The cotton wool thus dropped is collected in the suction port 64 by the air flow from a fan (not shown) arranged in front of the flyer rail cover 63 and the suction air flow of the suction port 64. A part of the air flow blown out from the air outlet 36 is directed upward by a roller or the like, and indirectly acts on the fly dust accumulated on the top arm 4 or the like to drop it.

Other Embodiments Another example of the diverting means 40 is shown in FIG. Here, the blow tube 30 is horizontally fixed while being fixed between the left and right top Amens frame bodies 32. The blowout port 36 is directed toward the top roller 5a. A pair of deflecting plates 71 pin the upper end of the intake pipe 30 so as to sandwich the blower port 36 in the front and rear direction, and the bent portion 20a at the tip of the connecting plate 20 is pin-connected to the intermediate portion thereof. As described above, the deflecting means 40 is shown as a louver structure using the deflecting plate 71 in this embodiment. Therefore, when the connecting plate 20 moves back and forth by a predetermined amount, the deflecting plate 71 changes its angle, the direction of the air flow blown out from the air outlet 36 is continuously changed, and the roller part 2 is cleaned over a wide range.

Effect of the Invention As described above, according to the device of the present invention, the airflow discharged from the air outlet of the air blow pipe provided above the roller part is periodically changed in the front-back direction. The blowout airflow can be directly applied to the entire roller part simply by arranging it in a line along the line, and the entire roller part can be reliably cleaned with a small amount of air. As a result, the cotton wool accumulation on the roller part is reduced, the cotton wool is less mixed into the sliver, which contributes to the improvement of the quality of the roving yarn and the periodic cleaning cycle by the operator can be lengthened. Moreover, since the connecting plate having the comb for cleaning the top clearer cloth is also used as the drive of the deflecting means for deflecting the air flow blown from the blower tube, it is not necessary to separately provide a drive device dedicated to the deflecting means. There is also an advantage that the configuration is easy.
