Definitions
- the invention relates to a thread storage and delivery device for textile machines with primarily irregular thread consumption, such as knitting and warp knitting machines which pattern, jacquard, curl, plate, oscillate and e.g. are semi - or fully plushable, with a storage body (9) on which the thread (3) to form a storage roll (8) can be wound tangentially and then overhead, i.e. is axially removable, the thread between the annular or circular end face (9 ') of the storage body and the ring - or circular, in the same direction and at least the same speed, axially displaceable counter-braking surface (10) Braking is slowed down so that the thread take-up tension can be set to the required value regardless of the thread consumption of the textile machine and remains constant over long distances.
- the storage capacity required for this is automatically replenished again and again by an arrangement for the required speed control of the storage body drive, which is not explained here.
- Known devices of this type generally have the disadvantage that the thread drawn off from the storage body in the axial direction prevents any lifting or flying away from the storage body by any annular arrangement loosely seated on the storage body (metal ring, plastic ring, comb-like plastic ring, brushes and the like) is, however, can not produce the desired and required for a correct knitting process thread pull-in tension of the thread on the respective knitting system on the machine). Rather, the thread runs from the storage body at a considerably lower tension than it is usually fed to the storage body. An additional thread brake between the storage device and the knitting machine must then provide the final and, above all, knitting-appropriate infeed tension on the system of the knitting machine.
- a thread storage and delivery device for textile machines is known (German patent specification 1 635 899), equipped with a winding body on which the thread can be tangentially wound to form a thread supply and from which it can then be pulled off axially, namely through a so-called ring traveler. which runs around a flange at the head end of the winding body.
- ring traveler which runs around a flange at the head end of the winding body.
- the object of the invention is therefore to provide a thread storage and - delivery device of the type described above, which has the desired features, is simple in structure and function and also works reliably in all areas of use intended for this purpose.
- This object is achieved in that the The thread (3) to be processed when axially withdrawing from the storage body (9) is more or less clamped or braked by means of a second annular or circular braking surface (10) on its annular or circular end face or head side (9 '), which is arranged to be displaceable parallel to the former and, moreover, preferably executes the same relative rotary movement as the storage body (9) at any desired time.
- the invention is based on the idea of combining the completely different functions such as a device for preventing balloon formation and that of an ideal, continuously adjustable thread brake in a relatively simple construction, the other essential features of a thread delivery device which can be used practically anywhere being taken into account
- the counter-braking surface which is arranged parallel to the storage body and executes the same relative rotational movement as this at any point in time, the aforementioned functions are essentially already fulfilled
- the counter-braking surface (10) consists of a thin and flexible disc be made of a wear-resistant material and slightly larger in diameter than the end face of the storage body (9 '), by means of a further pressure-elastic disc (11), which itself is attached to a rotatable, stable, low-mass retaining disc (12) together with the hub (13), as required more or less pressed against the end face
- the thread (3) which is now clamped by the two braking surfaces depending on the contact pressure, is drawn off via the center of the counter-braking surface (10) .
- the counter-braking surface has, for example, a ceramic eyelet (25) in its center, which also has the task of centering the flexible counter-braking surface.
- the entire structure is centric and flat via a hollow shaft (17), which serves for unimpeded thread withdrawal in both planes to the storage body or its braking surface (9 '), rotatable and displaceable in parallel, mounted.
- the counter braking surface consists only of a more stable disc, which has, for example, a ceramic eyelet in its center and is attached to the hollow shaft via a hub.
- This embodiment entails a more critical thread tension adjustment.
- Thread guide means (5, 6, 7) associated with the storage body are advantageously connected fixed to the device chassis (2), the functional block with the counter-braking surface is therefore preferably displaceable on a in the longitudinal axis of the storage body Carriage (26) mounted.
- the device according to the invention works as follows: Before starting the knitting machine, switch off the device with switch (24).
- the thread (3) to be processed is threaded through the eyelet (5), the thread brake (6), the eyelet (7) and then transversely between the front side of the storage body (9 * ) and the counter braking surface (10) beyond the center and the ceramic eyelet (25), pushed approximately into the rear third.
- a threading aid the thread is pulled through the hollow shaft (17) and attached to the For the first winding of a supply or storage reel (8), it is advantageous if there is a small loop on both the thread inlet and outlet side and a slightly higher clamping effect of the two braking surfaces.
- FIG. 1 is a side view of a device according to the invention in the housing
- FIG. 5 shows a vertical section through another embodiment of a counter braking surface
- FIG. 6 shows a vertical section through a further embodiment of a counter braking surface
- FIG. 8 shows a partially cut-open storage body with storage roll in a side view together with a further embodiment of a counter braking surface in vertical section
- Fig. 9 is a side view of another exemplary embodiment, partially in longitudinal section, with a common drive motor for both storage body and counter braking surface.
- Figures 1 and 2 show an overall view of the device once with and once without various housing covers from the side.
- This type of device is usually used with the aid of a holding bracket (1) on a holding rod, which usually has space for several devices, and the is in turn attached to the knitting machine, mounted near the knitting point to be supplied.
- the thread run through the device can be followed well: the incoming thread (3) is brought tangentially to the storage body (9) by means of the inlet end (5), the thread brake (6) and the guide end (7) a number of turns to form a storage roll (8).
- the thread is then passed or clamped between the front braking surface (9 ') of the storage body (9) F and the counter braking surface (10), and over the centrally located ceramic jug (25) and the
- FIG. 8 also shows a centrally mounted compression spring (11 '), which has the task of increasing or increasing the contact pressure of the counter braking surface (10) with the front braking surface (9') F of the accumulator body (9) to stabilize.
- the sliding carriage (26) on which the motor (14) for the counter-braking surface (10) is fastened is also visible in Figure 2.
- the carriage is moved depending on the position via the threaded rod (16) on the chassis (2), ultimately the counter braking surface (10), more or less pressed against the front braking surface of the storage body via the spring (11 * ) and the elastic disc (11).
