TRAVELING CLEANER Filed NOV. 9, 1956 2 SheetsSheet 2 INVENTOR. 606E M Az 4/6 ATTORNEY Unite The present invention relates to cleaning apparatus for machinery and other equipment and relates more particularly to freely suspended means for generating and discharging a current of air at localized areas.
Presently, traveling cleaners in which a large motorized blower unit is supported move along a trackway suspended above the machinery to be cleaned. Discharge openings in a scroll or duct attempt to present adequate air under pressure at the required elevation but the inflexibility of the arrangements thus far utilized have made the installations of this equipment cumbersome and costly. Frequently a single impeller is employed to produce a large volume and high velocity of airwhich air will flow from a plenum chamber into various sheet metal outlet ducts which ducts due to their weight and inflexibility must be installed appreciably above the operating equipment. Remoteness of the impeller from the area to be cleaned requires greater motive power to produce ade-' quate air volume and velocity for a specific application.
Therefore, it is an object of the present invention'to provide a blower unit capable of discharging a volume of air at a specific elevation or a number of elevations with the blower unit being flexibly suspended.
Yet another object of the invention is to provide an apparatus for continuously discharging streams of air at selected elevations as well as along a floor surface.
Another object of the invention is the provision of a traveling cleaner for machinery in which a blower unit is suspended for flexible or unrestricted displacement about the position of suspension to discharge a stream of high velocity air at the desired elevation.
It is further contemplated to provide a traveling cleaner apparatus in which a plurality of blower units may be suspended freely at selected elevations from a traveling carriage by means of a flexible connection to produce a flow of a number of high velocity air streams.
Other objectsand many of the attendant advantages of this invention for discharging high velocity streams of air for cleaning machinery at various elevations will become better understood from the following detailed description taken in conjunction with the accompanying drawings in which like characters of reference designate corresponding parts throughout the several views, and wherein:
FIG. 1 is an end elevational view of one embodiment of the present inventive concept with application to a spinning frame;
FIG. 2 is an enlarged partial longitudinal sectional view taken of the top portion of one'blowing station within a flexible tubular casing;
FIG. 3 is an enlarged partial longitudinal sectional View of a modification of the blower units illustrated in FIG. 2 in which impeller blades are mounted in spaced vertical relationship;
FIG. 4 is a transverse sectional view taken substantially along the plane of section line 4-4 of FIG. 1;
FIG. 5 is a partial side elevational view illustrating a floor blower unit for attachment to the end of a flexible supporting means;
FIG. 6 is a transverse view of the floor blower unit taken substantially along the plane of section line 66 of FIG. 5;
FIG. 7 is a front elevational view of a modified form of combination traveling cleaner with portions of a suspended duct removed.
Referring to the-drawings and particularly to FIG. 1
States Patent it there is illustrated an assembled cleaner traveling carriage 10 movable along a suspended trackway 11 by means of the carriage wheels 12 which trackway is suspended over a spinning frame 13 or other machinery to be cleaned by means of air streams passing thereover. The traveling carriage may be driven along the t-rackway by conventional means contained Within the carriage housing 14 and this means does not constitute any portion of this invention. Conduit cross-arms 15 and 16 extend transversely from their mountings on the traveling carriage for a suitable distance beyond the carriage to receive a vertical duct 17 at the end thereof.
Each of the vertical ducts 17 mounted at the end of the cross-arm members 15 and 16 is connected to the cross-arm by means of a ring 18 or other suitable flange type connection. Although a fixed connection is illustrated, it is contemplated, where desirable that a swivel connection may be provided. Duct 17 extends vertically and is made of a woven tubular fabric that is freely displaceable or yieldable in any direction. To maintain the duct in extended substantially cylindrical contour, vertically spaced duct stiffener rings 18a or the equivalent may be provided to prevent collapse of the tube.
In the embodiment illustrated in FIGS. 1 and 2 there is included a plurality of individual motor driven fan blower units 19 each having a small motor 20 which drives an impeller within a scroll type casing 21. The motor driven fan units 19 are supported by suitable fastening means within the duct 17 in vertically selected spaced intervals depending upon the required discharge level for the air. The scroll casing 21 is provided with an outlet nozzle 22 that may be directed through an opening 23 Within the vertical duct. Suitable vanes may be provided in the outlet opening or the duct to direct a stream of air discharged from the blower units. Electrical current may be supp-lied to the motors by means of the cable 24 which receives current from a bus bar (not shown) on the trackway. Cable 24 passes through a conduit cross-arm to the individual motors within the duct.
One such modification to theterminal end of the duct to provide a floor sweeping unit 30 is illustrated in FIGS. 5 and 6. This floor sweeping unit 30 may be attached or assembled within the duct 17 at the lower end thereof so as to discharge air along the floor. In large spinning rooms the trackway is usually arranged in parallel runs and the machines in a bay will be cleaned prior to the carriage traveling to the next bay. Initially the blower unit at the floor will blow in one direction but as the carriage travels to the next bay the blower at the floor will blow in the opposite direction thus shifting any lint back to the original position. While the blower units in the higher levels of the duct may blow in opposite directions after making a traverse, the floor unit will have to continue to blow in a single direction. To carry out this objective the blower unit 30 is provided With a scroll casing 31 having double outlets 32 and 33 discharging in opposite directions. By means of the movable louvre bafiles 34 and 35 in the outlets 32 and 33, respectively, the air stream direction may be controlled. Obviously, opening and closing or the sequential operation of the baffles 34 and 35 may be operated automatically by meanstof solenoids, microswitches or by means of'mechanical linkages.
Although it is preferred that individual motor blower units be employed within a vertical freely suspended duct, a vertically suspended strip may be used to fasten the 3 motors in vertical arrangement as well except that the casing of the units will be exposed. The objective sought is that the motors may be displaced freely upon striking an obstacle and then return to the desired vertical position as the carriage moves beyond the obstacle.
The use of individual motors as described above is most desirable, however, a single motor 40 may be supported in the hood 41 of a vertical duct, as shown in FIG. 3, with the motor being supplied with electrical current from the conductor leads 42 which leads communicate with a bus bar (not shown) at the trackway. The shaft 43 of the motor extends downwardly to drive a flexible shaft '44 that is suitably guided in spaced bearing plates, such as plate 45 supported in the duct 46. Propeller type blades 47 or impeller blades of other types may be mounted in spaced vertical relation within the duct on the flexible shaft. Expander sleeve members 48 are supported in the duct and surround the blades to eliminate the pos sibility of striking and cutting the fabric duct.
A floor blowing unit as illustrated in FIGS. and 6 may be assembled on the bottom end of the duct 46 and the blower unit will be driven by means of the flexible shaft.
A combination traveling blower unit is shown in FIG. 7 in which a traveling carriage 60 moves along an overhead track 61 with a motor 62 having a double end extending shaft for driving blower units adjacent to and distant from the motor. A double discharge scroll casing 63 is mounted on each end of the motor 62 which drives an impeller at each end thereof to discharge an air stream below the trackway from the discharge nozzle 64 and above .the trackway from the discharge nozzle 65. Air discharged from the nozzles 65 at each end of the motor are conducted by means of the sheet metal ducts 66 and 67 to the plenum chamber 68 which will discharge the air upwardly from the pivotable nozzle 69.
It is frequently desirable to sweep a selected area above the trackway and by pivoting the discharge nozzle 69 through a selected are the area above the trackway may be blown clean. The nozzle 69 is cooperatively received within the spherical plenum chamber. A projecting arm 70 is fastened to the nozzle 69 and a vertical link 71 is fastened at one end to the free end of the arm 70 with the other end of the link 71 fastened to an eccentrically mounted pin-on the rotatable slotted wheel 72 which wheel is fastened to the carriage. As the carriage moves along the trackway, the wheel 72 will strike a cam plate 73 which plate will rotate the wheel through a predetermined arc of rotation thereby displacing the vertical link 71 which in turn will shift the end of the arm 70 to pivot the nozzle 69 to another position.
A duct 74 reaches from each scroll casing 63 and is provided with an elbow housing 75 to which is fastened a freely displaceable duct 76 similar to that described above in FIG. 3. A motor shaft extension 77 reaches horizontally into the housing 75 and has a bevel gear 78 mounted thereon to drive the bevel gear 79. Bevel gear 79 is supported on the vertical shaft 80 that is rotatably mounted in the plate flange 81. A coupling 82 connects the shaft 80 to the flexible shaft 83 on which flexible shaft there is mounted a plurality of vertically spaced impeller zontal from the depending freely displaceable duct members. Floor cleaning units may be assembled at the ends of the flexible ducts of the type shown in FIG. 5.
Obviously many modifications and variations may be made in, the construction and arrangement of the flexible or yieldable freely suspended duct and the disposition of the blowing units in the light of the above teachings without departing from the real spirit and purpose of this invention. It is, therefore, to be understood that within the scope of the appended claims many modified forms of structure as well as the use of mechanical equivalents may be reasonably included and modifications are contemplated.
