BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to an apparatus for removing dust, lint, and other waste products from textile machines.
On textile machines, it has already been customary for a long time to employ travelling cleaners, by means of which the fabricating stations of the textile machines are swept by blowing-air and/or suction-air streams, in order to keep freed lint and dust away from the fabricated fiber material or thread material or to reduce its precipitation on the machine.
At the same time, devices, in which the travelling cleaners move on a runway past a plurality of textile machines swept in succession, have also already become known. In these, the runway is usually supported on the machines themselves or on the floor by means of pillars.
The examination of yarns and fabrics has shown that these have an astonishingly high content of lint and dust. Thread breaks occur relatively frequently in the textile fabrication processes themselves, these being attributable, among other things, to the high content of impurities in the ambient air or to accumulations of impurities at fabricating stations.
SUMMARY OF THE INVENTION
The object of the invention is, therefore, to provide an apparatus, by means of which the impurities can be markedly reduced, at all events in the critical fabrication regions, at comparatively low investment costs.
This object is achieved, according to the invention, by means of a traveling cleaner, moving on a runway wherein there extends parallel to the runway an air channel which supplies at each textile machine a downwardly directed piston flow outlet, the air channel being connected to an air treatment system, and exhaust ports connected to a suction channel and arranged in the floor.
As a result of the cooperation of a controlled piston flow flowing continuously through the fabrication zones of all the machines with a travelling cleaner passing periodically in the vicinity of the fabrication zones, a marked reduction in the number of thread breaks and an improvement in the quality of the fabricated textile material are achieved. This is attained because the work zone is kept virtually free of dust by means of the displacement flow and because the risk of accumulations of impurities on machine parts critical for fabrication is avoided by means of the travelling cleaner. Because the air channel runs parallel to the runway of the travelling cleaner, straight paths are obtained both for the flow and for the movement of the travelling cleaner and intersection problems can be avoided.
Further advantages of the apparatus according to the invention and preferred embodiments of the invention are described further below.
DESCRIPTION OF THE DRAWINGS
The apparatus according to the invention is explained in more detail below by means of exemplary embodiments with reference to the drawing. In this:
FIG. 1 shows a side elevational view partially in section of a first exemplary embodiment of an apparatus for a textile-machine room;
FIG. 2 shows a plan view of the apparatus according to FIG. 1;
FIG. 3 shows a vertical section along the line III--III in FIG. 2;
FIG. 4 shows a second exemplary embodiment in a representation corresponding to that of FIG. 3;
FIG. 5 shows a portion of an air channel from a third exemplary embodiment in a perspective representation; and
FIG. 6 shows a partial side view of the third exemplary embodiment in FIG. 5.
PREFERRED EMBODIMENTS
As is shown in FIGS. 1 and 2, weaving machines 4 are arranged in a plurality of parallel rows 6 in a weaving room 2. A runway 8, closed on itself, of a travelling cleaner 10 known in the art extends over every two directly adjacent rows 6. The runway 8 has, in addition to straight parts 12 parallel to the rows 6, arcuate parts 14 connecting the parts 12 to one another.
Air channels 16 extend parallel to the straight parts 12 of the runway 8 above the rows 6 of weaving machines 4. A downward-directed piston-flow outlet 20 is provided above each weaving machine 4 on the undersides 18 of the air channels 16. By a pi
