Definitions
- the invention has for its object to provide a thread delivery device of the type mentioned and a thread brake for such a thread delivery device, in which, while maintaining the important advantage of the self-compensation effect, an influence on the thread take-up tension level due to varying pressing force in the circumferential direction can be avoided and the thread brake is easy to manufacture and handle .
- the brake band carrier acts on the brake band in the braking zone and also in the vicinity thereof.
- Thread brake equipped thread delivery device
- a thread delivery device F equipped with a thread brake B, possibly forming a separate unit, has a drive motor 2 for a winding member 3 in a housing 1.
- a drum-shaped storage body 4 is arranged on the housing 1 and has a trigger edge 5 which is continuous, rounded or conical in the circumferential direction.
- the thread brake B is supported in a stationary manner in a holder 9 which is expediently axially adjustable in the direction of a double arrow 6 and is arranged in a housing bracket 7.
- An approximately ring-shaped brake band carrier T is supported in the holder 9 and presses a brake band A which is continuous in the circumferential direction approximately in the axial direction (axis X of the storage body) against the trigger edge 5.
- the brake band consists of a wear-resistant material, for example a metal or a metal alloy in a thickness between 0.01 and 1.0 mm, and has the shape of a truncated cone.
- the brake band A is resiliently deformable at least in directions perpendicular to the truncated cone generators, but is otherwise tensile.
- FIG. 1 it is indicated that the brake band carrier T has the brake band A with individual arms C projecting freely in the circumferential direction at the ends. edge 5 presses.
- the storage body 4 is arranged stationary in this embodiment shown. Alternatively, however, the thread delivery device F could also have a storage body 4 which can be rotated about the axis X. It would then have to be ensured that the thread brake C, at least the brake band carrier T, is able to turn. If necessary, even a rotary drive for the brake band carrier T is then provided.
- the brake band A is floating on the trigger edge 5 and on the brake band carrier T or the arms C.
- a brake band holder H which may consist of individual holding elements distributed in the circumferential direction, prevents the brake band A from falling out, provided the thread brake B is released or during its assembly.
- the brake band holder H is also expediently designed as an annular thread guide element L which controls the entry of the thread into the thread brake B and also influences or limits the formation of a thread balloon.
- the brake band carrier T is fixed to the ring 8 in the holder 9 and has arms, spokes, lamellae or pins 15 which project freely inwards from the ring 8 and which extend in the circumferential direction are separated from one another by intermediate distances 18.
- Each arm 15 is designed to be resilient and has an abutment area 16, which on the rear of the brake band A is approximately aligned with a brake zone Z formed between the inside of the brake band A and the trigger edge 5.
- the brake band A is floating in the circumferential direction and in the direction of its truncated cone generators in the brake band carrier T, e.g. even with a game of movement.
- the thread guide element L which can be fixed in the holder 9, defines an inlet gap for the thread and forms here with its inner edge region the brake band holder H.
- projections 14 can engage in the spaces 18 and complete the brake band holder.
- the brake band carrier T can be made of plastic and / or metal, e.g. be made of resilient sheet metal with individual cut-out tongues.
- the axial preload that the brake band carrier T transmits to the brake band A can be thanks to the suspension of the arms 15 e.g. adjust by the axial position of the holder 9.
- a conical support body 26 of the brake band carrier T is formed on the ring 8, which can be designed to be inherently rigid and supports an annular spiral spring 28 in a receptacle 27, the spring windings 28a (FIG. 10) Define individual contact areas 16 on which the brake band A is mounted.
- the spring turns 28a of the spiral spring 28 are expediently inclined relative to the spring axis 29 in order to achieve a softer spring identification of the contact areas 16.
- the brake band carrier T simultaneously forms the thread guide element L and the brake band holder H. In FIG. 11, the inner edge of the brake band A is also encompassed by the support body 26 with movement play.
- the circular spiral spring 28 is used for power transmission.
- An inner bead 30 serves as an additional brake band holder H. If necessary, the inner bead 30 is designed to be wear-resistant by plasma coating or in some other way in order not to wear out when it comes into contact with the thread.
- the spiral spring 28 is positioned in the receptacle 27 by holding devices (not
- the arms 15 on the ring 8 are bent in an S shape in order to achieve a greater spring length and to act in the contact areas 16 with forces directed approximately perpendicularly to the trigger edge 5.
- the thread guide element L and the brake band holder H are provided.
- the brake band A does not directly touch the contact areas 16, but rather an interposed wear element V which is expediently also in the form of a truncated cone is interposed, which is designed to be slippery on at least one side or is made of slippery and low-wear material. It is conceivable to fix the wear element V with the brake band holder H, or to let it grip over the outer edge and / or the inner edge of the brake band A.
- the spring device 33 is expediently adjustable, in order to be able to adjust the axial preload of the brake band A on the trigger edge 5 of the storage body 4.
- a suitable material for the truncated cone shell 31 would be thin plastic fabric reinforced with carbon fibers.
- an independent thread guide element L (not shown) could be arranged separately from the thread brake B on the extension arm 7 of the thread delivery device F (shown in FIG. 13).
- the brake band carrier T of the thread brake B consists of a truncated cone-shaped ring body 8, 26, which is supported in the holder 9, and a conical ring 36 made of soft elastomer or rubber or foam, which is fixed to the ring body 26 and that Floating brake band A presses against the trigger edge 5.
- the thread guide element L with the brake band holder H can also be provided on the brake band carrier T so that the brake band A cannot fall out.
- the brake band A may even perform a rotary movement about the axis X, at least at higher thread speeds, whereby the pressure of the brake band on the take-off edge remains uniform in the circumferential direction and a favorable distribution of wear occurs. Thanks to the rotation, the brake band, which rotates slower than the thread circulation speed, contributes to a reduction in the thread take-up tension level, that is to say to favor the self-compensation effect because the relative speed between the thread take-off point and the brake band is lower than the relative speed between the take-off point and the brake band carrier T.
- a circumferential pocket 38 is formed on the brake band carrier T, which is made of an elastomeric material as an annular membrane M, within an optionally provided undulation 10 on the inside, and is formed by a pocket over the outer edge of the brake band A gripping, preferably elastic lip 37 is limited.
- individual ear-like lip sections 37 'could also be provided, which define a plurality of pockets 38' distributed over the circumference for inserting the brake band A.
- a plurality of circumferentially distributed, arcuate slots 40 are introduced, each of which delimits an ear 39 which engages over the outer edge of the brake band as soon as it is installed.
- the lip 37, or the sections 37 'or the ears 39 of FIGS. 16 to 18 can lie on the brake band A with elastic pressure.
- the extension of the lip 37, 37 'or the ears 39 is expediently predetermined such that the outer edge of the brake band A is unable to come free under operational stresses in the brake band carrier T or the working movements of the brake band A.
- Three sections 37 'or ears 39 in a regular distribution along the circumference of the brake band A are sufficient. However, a larger number is expediently provided for security reasons.
