Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a pneumatic flute arranged under the front bottom roller of a spinning machine, a function of sucking fiber waste when the yarn spun from the front bottom roller is broken, and a cotton wool or fiber waste attached to the outer periphery of the front bottom roller. It relates to a new muffler that also has the function of sucking in.

[0002]

[Prior art]

 A device disclosed in Japanese Patent Publication No. 36-17409 is disclosed as a device in which fiber scraps adhering to the surface of the front bottom roller are peeled off by a clearer pad. In this device, clearer material such as leather or synthetic rubber is attached before and after the air intake port of the pneumatic duct toward the front bottom roller, and the upper end of the clearer material is pressed against the outer circumference of the front bottom roller to attach the fibers to the surface of the front bottom roller. Dust or fiber dust wrapped around the outer circumference is peeled off from the front bottom roller and sucked into the pneumatic duct.

[0003]

[Problems to be solved by the device]

 In the conventional clearer device, a clearer pad is attached to the front and rear of the suction port of the pneumatic duct to clean the front bottom roller, so the fiber dust attached to the outer periphery of the front bottom roller can be immediately transferred to the pneumatic duct. Can be aspirated. Now consider the case where this technology is applied to the front bottom roller of a spinning machine. If the yarn being spun is broken, the suction airflow of the pneumatic duct is blocked by the clearer pad in front of the suction port, so there is no suction airflow forward of the front bottom roller in the spinning direction. It is necessary to separately arrange a pneumatic flute for suctioning the broken fiber under the roller. As a result, there are problems that it is economically unfavorable, for example, there are two pipes for suction and the suction capacity becomes large.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is arranged on the lower side of the front bottom roller, and in a pneumatic flute configured to generate a suction airflow from the suction holes, It features a clear pad for cleaning the outer circumference of the front bottom roller at the rear.

[0005]

[Action]

 The clear bottom pad, which is attached to the rear side of the suction hole of the pneumatic flute below the front bottom roller, cleans the outer circumference of the front bottom roller to clean the cotton dust or fiber dust adhering to the outer circumference of the front bottom roller. The suction airflow sucks into the suction port of the new muffler. Further, when the spun yarn from the front bottom roller is broken, the broken fiber waste is also sucked in through the suction hole.

【Example】

 The new muffler of the present invention will be described in detail with reference to the drawings in which the front bottom roller of the spinning machine is mounted. As shown in FIG. 1, 1 is a front bottom roller, 2 is a middle bottom roller, and 3 is a back bottom roller. The front bottom roller 1 is pivotally supported by roller stands 4 and 5 on both sides, and other bottom rollers. Numerals 2 and 3 are pivotally supported on slide metals 6 and 7 on roller stands 4 and 5, respectively. These bottom rollers 1, 2 and 3 are adapted to be rotated via a drive transmission mechanism for transmitting drive from a drive source (not shown). Further, a front top roller 8, a middle top roller 9 and a back top roller 10 are arranged above the bottom rollers 1, 2 and 3 to form a draft roller portion 11. Each of the top rollers 8, 9 and 10 is pivotally supported by a top arm for wetting (not shown) so that a weighting load is applied to each of the bottom rollers 1, 2 and 3 by a well-known weaching device. At the rear of the draft roller portion 11, a guide 12 for the roving R is attached to a traverse bar 13 which is movable on the slide metal 7 in the longitudinal direction of the bottom roller by a predetermined amount.

The new muffler is shown at 20, and is shown as being provided independently on the front bottom roller 1. The pneumatic flute 20 as described above is provided at each interval (staff) between the roller stands 4 and 5 and has a cylindrical suction member 21 formed to have the length of the staff. A suction hole 22 for sucking the fiber waste, which corresponds to the passage portion and communicates with the hollow hole portion 21c, a clearer pad 23 attached to the rear of the suction hole 22 and the suction member 21 attached to both ends of the suction member 21. It is composed of a support member such as a connector which will be detachably supported on the roller stands 4 and 5. As shown in FIG. 2, the suction member 21 is attached to the roller stands 4 and 5 by pressing the coupling member 16 by the pressing force of the spring 15 mounted on the holder 14 provided at the end of the suction member 21 to the engagement member 16. It is pressed and supported by the engaging hole 4a of the stand 5, and a water drop type connector 17 is inserted into the suction member 21 at the other end. For the attachment to the roller stand 4, a fitting hole 17a is provided on the roller stand side of the connector 17, and an engaging projection 4b provided on the roller stand 4 while being fitted so as to be fitted on the outer periphery of the circular support projecting edge 18 of the roller stand 4. While rotating the connector 17 so that the engaging hole 17b of the connector 17 is fitted to the engaging hole 17b, the engaging hole 17b and the engaging protrusion 4b are aligned so that the connector 17 is pushed into the supporting projecting edge 18 when the both are aligned. There is. To remove the connector 17, the connector 17 can be removed from the support projecting edge 18 by moving the suction member 21 in a direction against the spring force of the spring 15.

A duct hole 4c is provided in the center of the support protrusion 18 and communicates with the through hole 17c of the connector 17, and the through hole 17c communicates with the hollow hole portion 21c of the suction member 21, and a pneumatic air suction pneumatic cylinder (not shown). The suction airflow by blow acts on the suction holes 22 through the airflow holes 4d of the roller stand. Further, the suction hole width of the suction member 21 is set to a width L which is slightly longer than the movement distance of the spun yarn corresponding to the lateral movement amount of the guide 12. The suction hole 22 is provided with the above-mentioned clearer pad 23 formed of a clearer material such as synthetic rubber over the entire width of the suction hole 22 on the upper portion of the rear side plate 21b. Therefore, the suction airflow of the suction holes 22 reaches the point where the clear lap pad 23 comes into pressure contact with the outer peripheral surface of the front roller 1.

Next, the operation of the new muffler 20 will be described. In the state of FIG. 1, the clearing pad 23 behind the suction hole 22 presses the engaging member 16 of the suction member 21 into the engaging hole 4a of the roller stand 5 so as to contact the outer peripheral surface of the draft roller 1 with an appropriate contact pressure. The engaging hole 17b of the connector 17 at the other end is fitted into the engaging protrusion 4b of the roller stand 4 to fix the position. By doing so, the clearer pad 23 comes into contact with the outer periphery of the front bottom roller 1 with an even pressure contact force, and it is possible to peel off the fiber dust or the like that has adhered to the outer peripheral surface of the front bottom roller 1 or is thinly wound during operation. The fiber waste thus peeled off is immediately sucked into the suction member 21 by the suction airflow from the suction hole 22 and sucked into the pneumatic blower through the airflow hole 4d.

On the other hand, the fiber waste at the time of yarn breakage spun from the front bottom roller is also sucked into the suction hole 22 because the suction airflow acts in front of the front bottom roller 1. As described above, in the pneumatic flute 20 of the present application, the clearer pad 23 is attached to the rear of the suction hole 22. Therefore, the suction airflow is forward of the front bottom roller 1 and the suction function of the fiber waste at the time of yarn breakage, and the front bottom roller. It is possible to combine both the function of stripping the cotton wool from the outer peripheral surface of No. 1 and sucking this, and the suction system can be one system, and the air consumption can be reduced.

The present invention is not limited to the above embodiment, but may be as shown in FIGS. 3 and 4, for example. That is, the suction member 21A and the air flow suction side connector 17A are integrally fitted, and the outer periphery of the projecting edge 17B at the other end of the connector 17A is loosely inserted into the support holes 4B of the roller stands 4A and 5A to be rotatably supported. The outer periphery of the projecting edge 17B is hermetically sealed by a packing 29 attached to the support hole 4B. A locking pin 30 is integrally welded to the rear surface of the rear plate 21b of the suction member 21, and one end of a connecting rod 31 which is vertically engaged and disengaged is connected to the locking pin 30. The other end connects the suction member 21 to a swinging device 32 that swings in the front-rear direction, and a spherical bearing 34 of a bracket 33 provided on the rear side supports the connecting rod 31 slidably in the front-rear direction. .

A spring 36 for pressing the contact member 35 in the forward direction is mounted between the contact member 35 fastened to the intermediate portion of the connecting rod 31 and the bracket 33, and the contact member 35 is compressed by a compressive force. It is designed to urge forward. The contact member 35 is prevented from moving in the forward direction by a rotating cam 37 that is rotated by a drive system (not shown), and moves the connecting rod 31 back and forth by the contact member 35 that moves back and forth by the rotation of the rotating cam 37. Then, the suction member 21 may be swung so that the clear lap pad 23 is intermittently pressed against and separated from the front bottom roller 1. In this case, the clearer pad 23 is not always pressed, so that wear of the pad is suppressed.

Further, as shown in FIG. 5, a lower end of a swinging member 40 having a clearer pad 23 mounted on an upper portion thereof is swingably attached to a rear plate 21b of the suction member 21 so that the swinging member 40 has a locking pin. A connecting rod 31 connected to a swinging device 32 similar to that described above is detachably attached to 30a from above and below, and the swinging member 40 is swung by the swinging device 32 to move the clearer pad 23 to the outer peripheral surface of the front bottom roller 1. , It is also possible to press and separate.

[Effect of device]

 As described above, according to the present invention, the clear flute that cleans the outer periphery of the front bottom roller is attached to the rear of the new flute suction hole on the lower side of the front bottom roller. It can be sucked into the holes and prevents the cotton wool from being caught in the yarn being spun, improving the yarn quality. In addition, since a clearer pad is arranged at the rear of the suction hole, the suction airflow in the suction hole also extends to the front side of the front bottom roller, so that suction can be performed from the same suction hole as the fiber waste at the time of yarn breakage, and this makes the suction piping system for the new muffler. Can be made into one system, and air consumption can be reduced. Furthermore, since the clear pad is attached to the new muffler itself, when the clear pad is worn, it is easier to remove and install from the machine base compared to the case where a clear pad is provided separately from the new flute at the position behind the new muffler.
