Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for removing fluff and dust for a loom. More specifically, the present invention relates to a device for removing fluff and dust from a loom. This invention relates to a loom that is equipped with a dust removal device operated by a nozzle drive device that utilizes fluid pressure between the side frames of the loom and above the warp alignment surface in order to prevent it from adhering to the take-up beam, etc. It is something.

BACKGROUND ART A large amount of fluff is accumulated under the stand of a loom due to contact between warp and weft yarns and heddles or shuttles. This fluff is scattered in the air due to the inflow of outside air into the loom room, and it adheres to the warp threads and heddles that are lined up at predetermined intervals, causing yarn breakage and flying fluff. cause problems. However, most general-purpose looms are not equipped with devices for preventing the adhesion of fluff, and even for looms that are equipped with some kind of device for preventing the adhesion of fluff, their effects have not been noteworthy.

Problems to be solved by the invention Namely, since the specific gravity of fluff is extremely low, if the direction of air flow suddenly changes for some reason in the loom room, it easily flies up from the floor and damages the warp threads, etc. adhere to. This is because the warp yarns stretched in a flat state function as a kind of filter for the fluff that accumulates under the loom table, and the well-known suction type fluff and dust removal device. This is due to the fact that the vacuum cleaner is fixed between the frames of the loom or at a predetermined position on the table, and cannot exert a suction effect across the entire width of the loom. There was a strong demand for the development of a practical device.

In view of the problems of the conventional technology, the main object of the present invention is to provide a fluff and dust removal device for a loom that has a high ability to remove fluff and dust and has excellent operational stability. It's about doing.

Another object of the present invention is to provide a fluff and dust removal device for a loom, which has a fluid pressure nozzle drive device that produces non-rotating linear reciprocating motion in an air blowing nozzle and a fluff and dust suction nozzle. shall be.

Means for Solving the Problems In view of the above object, the present invention provides an air blowing device 32 disposed between the side frames 30 of a loom so as to be movable in a direction substantially perpendicular to the alignment direction of the warp threads 31. , a suction device 33 for air fluff and dust disposed above the warp alignment surface 31' of the loom so as to be movable in a direction substantially parallel to the air blowing device 32; The gist of the present invention is a fluff and dust removal device for a loom, which comprises a nozzle drive device 34 using fluid pressure that causes a cotton and dust suction device 33 to perform non-rotating linear reciprocating motion.

Embodiment FIG. 1 is a side sectional view of a loom illustrating the overall structure of the apparatus of the present invention, and FIG. 2 is a longitudinal sectional view of a nozzle driving device. 3 and 4 are cross-sectional views of an air blowing device and a fluff and dust suction device, respectively, which are attached to the nozzle driving device.

The apparatus of the present invention will be described below based on these drawings, but for ease of understanding, the nozzle drive device 34 will be explained first. As shown in Figure 2,
The hollow pipe 1 that functions as a guide member for the nozzle drive device 34 has an elliptical outer circumferential surface 17 on which the outer sliding member 5 is slidably fitted and supported along the axial direction of the hollow pipe. The inner circumferential surface 18 for slidably supporting the inner sliding member 3 along the axial direction of the hollow pipe is formed into a perfect circle. The hollow pipe 1 is made of a known metal material through which lines of magnetic force can pass, and its axial direction is made substantially orthogonal to the side frame 30 of the loom, corresponding to the operating range of the nozzle drive device, and the hollow pipe 1 is made of a known metal material through which lines of magnetic force can pass. The length is approximately equal to the distance between 30 and 30 mm. Inside the hollow pipe 1, an inner sliding member 3, which includes a plurality of first magnets 2 arranged concentrically with the inner circumferential surface 18 of the hollow pipe with a predetermined minute gap, is arranged along the axial direction of the hollow pipe 1. It is fitted so that it can slide freely. The inner sliding member 3 includes a support plate 19 that concentrically supports a plurality of the annular first magnets 2 in a laminated state, a presser plate 20, and an integral structure of the laminated support plate 19 and presser plate 20. Bolts 21 and nuts 22 to be tightened, sealing members such as O-rings 6 and first magnet 2
In order to maintain a predetermined gap between the outer circumferential surface of the hollow pipe 1 and the inner circumferential surface of the hollow pipe 1, the inner sliding piece, for example, a piston ring 7, is fitted on the outer circumference of the support plate 19. Corresponding to the inner sliding member 3, the non-circular outer circumferential surface of the hollow pipe 1 has a plurality of second grooves at a predetermined minute gap with the outer circumferential surface 18 of the hollow pipe.
The outer sliding member 5 has magnets 4 arranged concentrically,
It is slidably fitted along the axial direction of the hollow pipe 1. The second magnet 4 is the first magnet 2
The magnetic attraction force generated between these magnets is used to cause the movement of the outer sliding member 5 to follow the movement of the inner sliding member 3 in the axial direction. Therefore, as seen in FIG. 2, the relative positions of the first magnet 2 and the second magnet 4 are adjusted so that they face each other via the hollow pipe 1. The outer sliding member 5 holds the stacked body of the second magnets 4 via the retainer 10 and the housing 9 and an intervening plate 8 that concentrically holds a plurality of the second magnets 4 in a stacked state. The retainer 10 is fastened to an integral structure by bolts 11 and nuts 12, and there is a gap between the second magnet 4 and the non-circular outer circumferential surface of the hollow pipe 1 at the outer end of the inner circumferential surface of the retainer 10. an outer sliding piece for leaving a predetermined minute gap throughout the
For example, a dust scraper 24 made of an elastic material is fixed to the piston ring 13 and to prevent foreign matter from entering the minute gap between the second magnet 4 and the non-circular outer peripheral surface 17 of the hollow pipe 1. ing. The inner circumferential surface 23 of the outer sliding member 5 is processed to have the same shape as the non-circular outer circumferential surface 17 of the hollow pipe 1 so that the minute gap is substantially constant over the entire outer circumference of the hollow pipe 1.

In the above embodiment, the outer peripheral surface 17 of the hollow pipe 1 is formed into an elliptical shape, but the gist of the present invention is not limited to such an illustration, and the outer circumferential surface 17 of the hollow pipe 1 is formed into an elliptical shape. As long as the shape does not cause rotational displacement along the circumferential direction of the pipe 1, any shape such as a polygon or a serrated cross section with a spline formed on the outer peripheral surface along the axial direction of the hollow pipe 1 can be adopted. can. However, if uneven parts such as splines are formed, the processing process of the hollow pipe 1 becomes complicated and a special dust scraper 24 must be prepared. It is preferable to grind a pipe having a cross section and adopt an elliptical shape in which the ratio of the major axis to the minor axis is close to 1.

The nozzle drive device 34 formed in this manner is configured to reduce the pressure difference generated before and after the inner sliding member 3 and the first magnet 2 and the second magnet by introducing a pressurized fluid such as compressed air into the hollow pipe 1. The outer sliding member 5 and the inner sliding member 3 are simultaneously moved along the axial direction of the hollow pipe 1 at a predetermined speed using the magnetic attraction force acting between the two magnets 4. At this time, the rotational movement of the outer sliding member 5 is suppressed by engagement with the non-circular outer circumferential surface of the hollow pipe 1.
The nozzle drive device 34 can perform linear reciprocating motion along the axial direction of the hollow pipe 1 without rotating.

Therefore, as illustrated in FIGS. 1 and 3, the hollow pipe 1 is installed between the left and right side frames 30 of the loom over its entire length so as to be substantially orthogonal to the alignment direction of the warp threads 31. If the nozzle driving device 34 is fixed to the hollow pipe,
Air blowing device 3 fixed to the nozzle drive device
2 performs a linear reciprocating motion along the axial direction of the hollow pipe 1 over the entire width of the loom while remaining non-rotating, and blows away fluff adhering to the warp threads 31, the warp winding beam 35, the healds 36, etc. In the illustrated embodiment, the air blowing device 32 includes a nozzle body 37 for blowing air, a rubber hose 39 for supplying compressed air connected to the nozzle body 37 via a joint 38, and a rubber hose 39 for supplying compressed air. The rubber hose is connected to a compressed air source (not shown) via a compressed air supply pipe 49.

On the other hand, above the warp alignment surface 31' of the loom, a fluff and dust suction device 33 is slidably disposed parallel to the moving direction of the air blowing device 32. That is, as illustrated in FIGS. 1 and 4, above the warp alignment surface 31', two hollow pipes 1 are arranged parallel to each other and oriented in the horizontal direction over the entire width of the loom. The two sets of nozzle drive devices 34 that are slidably fitted and supported on the hollow pipe 1 include a suction duct 55 fixedly arranged over the entire width of the loom, and a dust hanger 5.
0, hanging bolts 51, 51', support bracket 5
2. A fluff and dust suction device 33 having a fluff suction nozzle 54 connected reciprocally along the longitudinal direction of the suction duct 55 via a suspended support member such as a nozzle support 53 is installed in series. ing.
The suction duct 55 is connected via an intake pipe 56 to a negative pressure suction device (not shown), for example, a neuma fill box. Therefore, the fluff adhering to the warp threads 31 and the fluff blown upwards of the loom while being carried by the high-pressure airflow ejected from the air blowing device 32 are collected by the suction nozzle 54 of the fluff and dust suction device 33. Negative pressure is suctioned from the tube, and the tube is housed in a neonatal file box (not shown).

Effects of the Invention As can be understood from the above explanation, by using the device of the present invention, it is possible to effectively remove the fluff adhering to the loom and the warp threads, as well as the fluff and dust accumulated under the table. I can do it.

The device of the present invention also allows the speed and direction of movement of the nozzle drive device to be adjusted steplessly by adjusting the magnitude of the magnetic attraction force and the pressure of pressurized fluid, such as compressed air, introduced into the hollow pipe. It can be changed freely and in a specific manner, and it is possible to reliably remove fluff and dust from the required parts of the loom.

Furthermore, in the present invention, by forming the outer peripheral surface of the hollow pipe into a non-circular shape, rotation of the outer sliding member with respect to the hollow pipe is completely suppressed. Even without providing a special guide device, a stable running posture can be ensured by the air blowing device and the fluff and dust removal device. Since the device of the present invention also has good sealing performance, there is no risk of dust or fluff entering the nozzle drive device from the outside, and it can be used for a long period of time virtually without lubrication.

In this way, the present invention, together with the simplicity of the structure,
It can also greatly contribute to extending the service life and reducing man-hours for maintenance work.
