APPARATUS FOR REMOVING THREAD WASTES ON THREAD CARRIERS USED IN TEXTILE MACHINES Filed Aug. 14, 1953 IIIIIIIIII FIG. 1
United States Patent APPARATUS FOR REMOVING THREAD WASTES ON THREAD CARRIERS USED IN TEXTILE MACHINES Walter Stutz, Kempten, near Wetzikon, Switzerland, assignor to Stutz & Cie., Kempten, near Wetzikon, Switzerland Application August 14, 1953, Serial No. 374,180
Claims priority, application Switzerland August 16, 1952 2 Claims. (Cl. 203-355) This invention relates to apparatus for removing thread wastes on thread carriers used in textile machines, particularly on spindles of weaving shuttles or bushings of spinning and twisting frames.
According to the invention this apparatus comprises a rotatable drum having a perforated cylindrical jacket, driving means for rotating the drum, means within said drum forming a chamber adapted to furnish a stream of air, said chamber being provided with an outlet slot for discharging said stream of air which passes through the perforated drum jacket and removes thread wastes adhering thereon.
The apparatus according to the present invention is automatically operative to remove thread wastes brought into proximity of the jacket of the revolving drum and engaged by the drum-jacket, the wastes adhering to the jacket while being pulled off from the spindles, and are then caused to be carried away by the air current discharged from said chamber through the perforated drumjacket and fed into a waste collector.
An embodiment of the invention is represented by way of example in the accompanying drawings.
Fig. 1 shows an axial section through the drum, and
Fig. 2 is a cross section.
1 designates the drum-jacket, supported by both end walls 2, which comprise hubs 3 serving for supporting the drum on the continuous shaft 4 which is arranged in two bearings 5. The drum contains a pipe 6, the diameter of which is somewhat smaller than the clear width of the drum-jacket 1. The pipe 6 has at each end a wall 7, which has openings (not shown) and a sleeve extension 8 traversed by the shaft 4. The pipe 6 is mounted on the shaft 4 by means of the two sleeves 8, which pass through both hubs 3 of the drum. The pipe 6 representing an air chamber has a longitudinal slot 9, which extends axially nearly over the entire length of the pipe; a plurality of longitudinal slots extending parallel to each other could be provided on the air-pipe 6. The shaft 4 carries four crosswise arranged blades 10, forming a blower; these blades 10 extend substantially through the same axial length as the mentioned slot 9. The drumjacket 1, provided on its outer face with an adhesive surface 11, e. g. made of felt, fabric, grooved rubber or the like, possesses a number of slots 12 equally distributed on its circumference and extending parallel to the axis of the drum, which slots may be longitudinally divided by cross ribs. The sprocket wheel 13 of a chain drive not further illustrated is mounted on the end of the shaft 4 situated in Fig. 1 on the right hand side; at the opposite end of the drum the sprocket wheel 14 of a chain drive not further illustrated is secured to the hub 3 of the drum; both chain wheels 13 and 14 form parts of the same driving arrangement. The pipe 6 is angularly adjustable but normally ice held from turning, for which purpose a set ring 15 having a locking pin 16 is provided at one bearing sleeve 8 of the pipe, which pin engages an abutment 17.
To use the described apparatus the drum 13 and the blower 4, 10 are rotated by the mentioned drive in a direction opposite to each other, as is indicated by arrows in Fig. 2. The air current produced by the blower 4, 10 in the pipe 6 is outwardly urged through the pipe-slot 9 and forced through the slots 12 of the drum-jacket 1. By means of the air-current thus discharged from the drumjacket 1, thread wastes collected by the latter are loosened from the revolving drum-jacket 1 and carried along with the conveying air, in order to subsequently, e. g. by gravity action, drift towards a waste collector or catching receptacle; in Fig. 2 a thread waste A is indicated by dot and dash-line.
The drum 1 and the blower 4, 10 could also rotate in the same direction. The thread carriers to be freed from thread wastes, e. g. those of weft bobbins or spindles of spinning frames, are temporarily delivered to a receiving station (not shown) provided above the drum 13, and the thread wastes of them are brought by mechanical or pneumatical means, or by hand, into proximity of the drum-jacket 1, in order to contact the adhesive lining 11 and thus adhere to the drum surface; however, a winding of the thread wastes on the revolving drum does not take place, since the thread wastes are continuously loosened from the drum-jacket by the exhaust or conveying air crossing the path of rotation of the drum-jacket and discharged through the perforations 12.
The described construction of the apparatus according to the .invention is characterised by its structural simplicity. The construction eventually might also be such that compressed air from the outside is axially, for example through shaft 4, supplied to the air chamber formed within the drum.
I claim:
1. A device for removing thread remainders from bobbins, comprising a hollow rotatable drum having a perforated cylindrical wall, means for rotating said drum, the cylindrical wall of said drum having an adhesive outer surface for catching a thread remainder coming from a bobbin, a stationary cylindrical chamber fitting inside said drum and having a longitudinal slot extending substantially the full length of said drum, a blower rotatably supported in said chamber and extending substantially the full length thereof and means for rotating said blower to blow air out through said slot, said slot being circumferentially spaced from a zone in which said thread remainders are caught on said drum so that said thread remainders travel part way around the drum and are then blown off by air from said blower when they reach said slot.
2. A device according to claim 1, in which said chamber is angularly adjustable to vary the circumferential lo cation of said slot.
