United States Patent Sharychenkov Aug. 26, 1975 1 DEVICE FOR NON-RING SPINNING OF FIBERS Primary Examiner-John Petrakes [76] Inventor: Alexandr Alexeevich Sharychenkov, Attorney Agent or Flrm Holman & Stem Ternovka, ulitsa Experimentalnaya l, kv. 67, Penza, U.S.S.R. [57] ABSTRACT [22] Filed: June 4, 1974 A device for a non-ring spinning of fibers is designed Appl. No.: 476,226
for use in non-ring spinning frames. The device is provided with a feeder and a twisting mechanism built into a housing and interconnected by a channel for transporting separate fibers. The channel is defined by two telescopically related cylinders, with the inner cylinder being rigidly coupled with the housing, and the outer cylinder, which freely envelops the inner cylinder, adjoining the twisting mechanism. With such a design of the channel, the outer cylinder can be moved with respect to the inner cylinder, affording access into the twisting mechanism. This arrangement results in a much simplified design of non-ring spinning devices.
2 Claims, 1 Drawing Figure DEVICE FOR NON-RING SPINNING OF FIBERS BACKGROUND OF THE INVENTION The present invention relates to pneumo-mechanical spinning frames, and, more particularly, to devices for non-ring spinning of fibers employed in such frames.
PRIOR ART There exists a known device for non-ring fiber spinning, which comprises a housing accomodating a twisting mechanism and a feeder. In this known device, the feeder is defined by pairs of draw rolls drawing the fibrous material to be spun, while the fibers of this fibrous material are transported to the twisting mechanism through a channel formed in the same housing. The part of the housing in which said channel is formed is rotatably mounted on the machine frame, so that when it turns, the housing with the channel is retracted from the twisting mechanism, thus affording access thereto. However, with part of the housing made rotatable, the prior art device for non-ring fiber spinning has an undesirably complicated design. Moreover, additional free space must be provided in the vicinity of each of such devices to accomodate the turned housing portion, which, with the frames being made up of a plurality of such single-type devices for non-ring spinning, renders the frames undesirably cumbersome.
The rotatable portion of the housing with a channel for fiber transportation cannot practically be used in devices for non-ring spinning with a feeder comprising a feed roller and a stripping roller, for at the joints of the feeder and the channel, as well as of the channel and the twisting mechanism, there must be provided intermediate moving parts. The presence of the latter implies a great number of gaps at the joints of said parts with fibers entering into these gaps, thereby obstructing the rotation of the housing portion with the channel for fiber transportion as well as the displacement of the intermediate parts.
It is likewise known to employ devices for non-ring fiber spinning, wherein the feeder and the channel for transporting fibers are disposed in a housing fixed on the machine frame, while the twisting mechanism is rotatably mounted on the frame, so that when the twisting mechanism turns relative to the fixed housing, access is provided into this twisting mechanism.
Wlth the twisting mechanism made rotatable, the device has a very complex design, all the undesirable design features being associated with the drive of the twisting mechanism and means for disconnecting the twisting mechanism from the drive as the former executes rotation.
OBJECTS AND SUMMARY OF THE INVENTION The present invention provides a device for non-ring fiber spinning, simple in design, affording easy and fast access into the twisting mechanism and of a sufficiently compact construction.
The above and other objects are attained in that in a device for non-ring fiber spinning, comprising a housing in which are built a feeder and a twisting mechanism interconnected by a channel for transporting separate fibers from the feeder to the twisting mechanism, in accordance with the invention, the twisting mechanism is fixed in said housing, while the channel for fiber transportation is defined by two telescopically related cylinders, the inner cylinder being rigidly coupled with the housing, and the outer cylinder having one end thereof adjoining the twisting mechanism, with the other end of the outer cylinder freely enveloping the inner cylinder, so that when the outer cylinder is dis placed with respect to the inner cylinder in case of a thread breakage or for rethreading, a free space is provided, thus affording access into the twisting mechanism.
With the fiber transportation channel defined by two telescopically related cylinders and the feeder and the twisting mechanism being fixed, easy and fast access is provided into the twisting mechanism when the outer cylinder rises relative to the inner cylinder. Such anarrangement further results in simpler designs not only of the feeder drives and twisting mechanism, but also of the housing in which they are disposed, since none of these members has to move to provide access into the twisting mechanism.
BRIEF DESCRIPTION OF THE DRAWING The invention will be better understood from the following detailed description of an exemplary embodiment of the proposed device, in accordance with the invention, taken in conjunction with the accompanying drawing in which the sole FIGURE is a line diagram of a device for non-ring fiber spinning in partial section.
DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawing, there is illustrated therein a device for non-ring fiber spinning, which comprises a housing 1, a feeder 2 defined by a constantly rotating feed roller 3 and a constantly rotating stripping roller 4, a channel 5 for transporting fibers and a twisting mechanism 6.
The channel 5 for transporting the fibers is so formed in the housing 1 as to communicate with the cavity 8. The channel 5 is defined by two cylinders 11 and 12 mounted in a telescopic relation, i.e. coaxially and movably one relative to the other. The cylinder 1 l is an inner one relative to the cylinder 12. The cylinder 11 is rigidly built into the housing 1, with cylinder 1 1 being formed as a recess 11a in the housing 1 and a bushing 11b secured to the housing 1 coaxially with the recess 1 la.
The cylinder 12 is an outer one relative to the cylinder 11. One end of the cylinder 12 adjoins the twisting mechanism 6, while the other end of the cylinder 12 freely envelops the bushing 11b of the inner cylinder 1 1.
To provide for a better contact between the cylinder 12 and the twisting mechanism 6, the cylinder 12 is fitted with a flange 13.
As the cylinder 12 displaces along the cylinder 11, a free space B is formed between the twisting mechanism 6 and the cylinder 12, thus affording access into the twisting mechanism.
In the example described herein, the channel 5 is defined by two telescopically related cylinders l 1 and 12.
3 However, this channel may be defined by three or more cylinders likewise mounted in a telescopic relation.
The drives of the feed roller 3, stripping roller 4 andtwisting mechanism 6 are not shown in detail, since these are mechanisms widely known in the textile industry which do not form the subject of the present invention. Y
The present device operates as follows:
The fibrous material A is delivered by any known method through the channel to the feed roll 3 which directs it to the stripping roll 4. The latter rotates, separating the fibrous material A into individual fibers which, at the area where the cavity 8 communicates with the channel 5, are removed from the card clothin 9 of the stripping roll 4 by the air stream through the channel 5 and transported along the channel 5 to the twisting mechanism 6 where the fibers are made into a thread. 7
in case of rethreading in the twisting mechanism 6 or of a thread breakage, the drives of the feed roller 3 and of the twisting mechanism 6 are disconnected. Then the outer cylinder 12 is lifted by hand, i.e. the cylinder 12 is thereby displaced along the inner cylinder 11, affording access into the twisting mechanism 6. There is no need to immobilize the outer cylinder 12 in its upper position shown by a dot-dash line in the FIGURE, so that the operator can wholly concentrate on the operation of rethreading. Yet, it is perfectly possible to employ means of retaining the cylinder 12 in its upper position, such as screws, pawls or springs (not shown). After splicing or rethreading, the cylinder 12 is lowered into the initial position, and the drives of the feed roller 3 and of the twisting mechanism 6 are activated on to start the spinning process again.
What is claimed is:
