Definitions
- the invention relates to a thread brake specified in the preamble of claim 1.
- a thread brake In a thread brake, the thread running through is mechanically braked by pinching and / or deflecting.
- thread brakes of various types are arranged in the thread path for the threads fed to a textile machine where an equalization of the thread tension, the build-up of a thread tension or a functionally required movement resistance for the thread is needed.
- a thread brake can also be provided between the storage and delivery device and the weaving machine on the inlet side of the storage and delivery device.
- the storage and delivery device is designed in such a case that the thread can be automatically threaded when starting up for the first time and when starting after a thread breakage, because manual threading with a threading needle is time-consuming and complicated .
- the thread brake is a weak point when threading, because the thread has so far only had to be threaded manually by the thread brake and in particular by its braking area, so that an existing automatic threading device is present other components cannot use their advantage.
- the gain in ease of use and downtime due to an automatic threading device for certain components along the thread path is partially nullified by manual threading in the thread brake.
- So-called crocodile brakes are known, in which the thread guiding elements can be brought manually into the threading position by folding their holding points in order to thread the thread by hand or by means of a threading needle. Even in the case of so-called multi-disc brakes with two brake discs pressed resiliently against one another or with a brake disc pressed against a fixed stop, the discs can be produced or the threading position can be produced manually.
- the invention has for its object to provide a thread brake of the type mentioned, which enables automatic threading of the thread.
- the thread brake is thus set up from the start for automatic threading, which is carried out automatically in a short amount of time.
- the drive puts the thread brake in the threading position for threading.
- the air guiding surfaces then limit the air duct in such a way that the air flow generated leads the thread through the thread brake and past the brake elements.
- the air flow can either be generated in the thread brake or outside, depending on how the air flow can best be brought into effect.
- the air guiding surfaces prevent the air flow from deviating sideways and the thread emerging from the side and ensure that the free thread end with the air flow flies quickly and without getting caught by the thread brake.
- the time required for threading is small. This principle is known to all Thread brakes, for example crocodile brakes, multi-disc brakes, disc brakes and the like. Like. Usable to be able to thread automatically.
- the drive types mentioned in claim 2 are expedient because a quick response and a trouble-free function when threading are ensured with relatively little structural and control engineering effort.
- a pneumatic actuator can also generate the airflow for threading.
- the embodiment according to claim 3 is expedient because, in addition to the setting of the threading position, the drive is able to modulate the braking action, possibly even remotely or automatically, for example depending on the thread speed or the thread quality.
- the drive acts against the elastic bias and unidirectionally. Nevertheless, the drive is able to modulate the braking effect by gradually counteracting the preload.
- the drive can adjust the braking element in both directions. This can be expedient in view of a quick start of operation of the thread brake after threading, because the drive resets exactly to a predetermined braking effect.
- the embodiment according to claim 6 is particularly important because the thread brake carries out a fully automatic threading. As soon as the thread break detector If the thread breaks, the drive brings the thread brake into the threading position. The air guiding surfaces define the air duct. By activating the pressure source, which can be triggered by the thread break detector, the air flow is generated which brings the end of the thread through the thread brake. As soon as the thread break detector detects the correct presence of the thread, the threading position is abandoned and the pressure source is deactivated. The thread brake is ready for operation again.
- thread brake elements are attached to two spread-apart holding arms, which deflect the thread in a zigzag shape in the spread braking position and define an elongated thread passage in the folded-in threading position (crocodile brake) Threading position the air guide surfaces on the holding arms and / or on the thread brake elements responsible for defining the air duct through which the air flow shoots the thread.
- the air guiding surfaces can be attached with little construction effort, the braking function is not impaired by the air guiding surfaces.
- the features of claim 9 are also expedient because the axial extensions of the thread eyelets have no noticeable influence on the braking effect during normal operation of the thread brake, but in the threading position provide for the formation of the largely closed air duct in a simple manner. Thread brakes that are already in operation can easily be retrofitted by replacing the short thread eyelets that are used per se with axially elongated thread eyelets.
- the embodiment according to claim 10 is expedient, in which the air guide surfaces are arranged on the holding arms.
- the air guiding surfaces are brought into their guiding position by the movement of the holding arms in the threading position.
- the air guiding surfaces on the base body are arranged from the outset in such a way that the air duct is limited in the threading position.
- a further embodiment, in which two resilient slats which can be folded against one another are provided on a base body, can be seen from claim 12.
- the air guiding surfaces on the surfaces of the fins do not affect the braking effect in normal operation of the thread brake. In the threading position, on the other hand, they help to guide the air flow that automatically threads the thread.
- this thread brake in which a stationary inlet opening with thread brake is provided in the base body, can be seen from claim 13.
- the air guide channel extending from the inlet opening to between the lamella surfaces ensures that the thread is not pushed sideways during the automatic threading in the threading position.
- the air duct can be provided on the lamellae in addition to the web-shaped air duct. With a special design of the air duct, the web-shaped air guiding surfaces on the fins can also be omitted. For this multi-disc thread brake, it may be appropriate to use the air flow generated for threading the thread also for moving the discs into the threading position.
- a further, alternative embodiment, in which a stationary elevation is provided on a base body with a stationary thread inlet opening as a counter-braking element, to which a plate mounted in the base body can be applied as a braking element, is apparent from claim 14.
- the air duct guides the air flow together with the slat and the riser.
- the air flow can simultaneously push the plate into the threading position of the thread brake.
- Air guiding surfaces and a pressure source are provided or Additional directional nozzles can be used to automatically thread the thread directly in the threading position when the plates are separated.
- a further embodiment of a thread brake with a base body, on which a stationary elevation for a brake element that can be resiliently attached to it is provided in the thread path, and with an adjusting device for the brake element, is evident from independent claim 15.
- This embodiment has independent inventive significance because the electromagnet directly influences the braking element across an air gap and sensitively modulates its contact pressure at the stationary elevation.
- magnets for influencing the braking effect of multi-disc brakes are known (US Pat. No. 4,641,688), in the known solution mechanical elements are adjusted by means of the magnet, which in turn act on the braking elements.
- the direct application of the metallic brake element by the electromagnet across an air gap is structurally simpler and leads to a sensitive and reproducible modulation of the braking effect.
- the magnet can adjust the braking element into the threading position, in which the thread, for example during automatic threading, is moved past the braking element without braking.
- the magnet so to speak, enables a fine adjustment of the previously roughly set contact pressure of the braking element.
- the aspect of claim 15 is important because the lamella in the threading position forms an active component for the directional guiding of the thread during automatic threading. Another useful embodiment of this thread brake is set out in claim 16.
- the joint attachment of the brake element and the magnet to the holder has the advantage that the contact pressure of the brake element can be roughly adjusted by swiveling the holder, and that the magnet is in constant spatial association with the brake element regardless of the swivel position selected the gap is predetermined so that the magnet brings its force for the plate into effect optimally and over a predetermined range without interfering with the normal working movements of the plate when braking.
- This embodiment is also useful for threading after a thread break, because after the lamella has been applied to the elevation, the magnet does not have to be readjusted to the lamella.
- the embodiment according to claim 18 is also expedient because the threading air nozzle uses the air flow in a targeted manner. As a rule, a single thread air nozzle will suffice. However, several threading air nozzles can also be provided. It is also conceivable to structurally combine a pressure nozzle with a suction nozzle in order to be able to generate a strong, directed air flow.
- a position of the threading air nozzle in accordance with claim 20 is favorable Extension area of the air duct or be arranged in the air duct.

- FIG. 12 is a top view of FIG. 11.
- a thread brake F K (crocodile brake) suitable for automatically threading a thread Y has a base body G, on which two holding arms 3 can be pivoted about parallel axes 4 which are spaced apart from one another. Intermeshing gears 5 connect the two holding arms 3 to a common, opposite spreading movement. A drive A engages one of the gears 5. The two holding arms 3 are through Feathers not shown (arrows 10) spread apart. The spring preload is adjustable. On the holding arms 3 are in the passage direction of the thread Y offset from one another with holding brackets 11 brake elements B, namely thread eyelets 2, which are elongated compared to conventional ring-shaped thread eyelets.
- a stationary thread eyelet 1 is provided on the inlet side in an inlet opening, which is preceded by a pressure nozzle 8 which can be connected to a pressure source P, 9.
- the pressure nozzle 8 can be fixed in place of the thread eyelet 1 in the base body.
- the pressure nozzle 8, like the pressure source P, can be separated from the thread brake. Only the air flow must be effective in the thread brake.
- the drive A can be an electric motor, a pneumatic cylinder or a mechanical drive 6, which can adjust the holding arms 3 into a threading position (FIG. 2). If necessary, the drive 6 replaces or supports the springs.
- a stationary thread eyelet 7 is attached to the output side.
- a thread break detector D is provided behind it, which monitors the thread Y and generates a signal in the event of a thread break.
- the drive A With the signal of the detector D, the drive A is switched on, which folds the holding arms 3 into the threading position (FIG. 2), in which the thread guide elements (pressure nozzle 8, thread eyelet 1, braking elements B, thread eyelet 7) are aligned with one another and define a continuous air duct .
- the elongated thread eyelets 2 form air guide surfaces L, see above that an air flow (indicated by arrows in Fig. 2) goes straight through the air duct and entrains the thread end.
- the intermediate distances Z between the braking elements B are expediently as small as possible.
- the drive A is deactivated.
- the holding arms 3 are spread again in order to deflect and brake the continuous thread Y in a zigzag shape.
- the pressure nozzle 8 is separated from the pressure source P, or the pressure source P, 9 is switched off.
- the thread break detector D does not necessarily have to be arranged on the thread brake itself. Any suitable control device in front of or behind the thread brake could perform this function. It is also conceivable to operate the drive A either remotely and automatically or manually by means of a pressure switch in order to adjust the thread brake F ⁇ to the single-thread position and to supply the pressure nozzle 8 with compressed air.
- the braking elements B in FIG. 1 can be trapezoidal thread eyelets 2 'in longitudinal section, which form the air guiding surfaces L with their longer inner bore parts and complement each other in the threading position according to FIG. 2 so that a continuous air duct is created.
- the short inner bore parts of the thread eyelets 2 ' act as desirably short deflection areas for a predeterminable braking effect.
- Modified thread eyelets 2, 2 'could also be in those that were already in operation Thread brakes F ⁇ are provided instead of the usual short, ring-shaped thread eyelets so that the thread brake F ⁇ is suitable for automatic threading.
- the holding brackets 11 of the holding arms 3 are expanded into wings 12 which form air guiding surfaces L and, in the threading position, limit the air duct from the outside.
- Conventional, ring-shaped and short thread eyelets can be used as the braking elements B.
- the wings 12 can be formed in one piece with the holding arms 3.
- a continuous wall 14 of the base body is provided as an air guide surface L on the left side of the holding arms 3, which wall closely adjoins the holding arms e and the braking elements B.
- a flap 15 can be pivoted back and forth about a pivot bearing 16 in the direction of a double arrow to illustrate a further alternative, which serves as an air guide surface L in the threading position.
- a flap 19 in the base body G in the direction of a Double arrow 20 to be pivotally mounted about a bearing 18 and serve as an air guide surface L, which is pivoted to the holding arms 3 when moving into the threading position to limit the air duct.
- the adjustment movement of the holding arms 3 into the threading position can also be used to derive the movements necessary for moving the flaps.
- FIGS. 9 and 10 show a multi-disc brake Fy suitable for automatic threading.
- two brake elements B resilient disks 21
- vertical bars 24 which can be rotated in opposite directions about the axes 4 by means of the toothed wheels 5 so that the disks 21 are pressed against one another with a prestress and define a brake gap.
- the ends 22 of the slats 21 are flattened.
- Drive A acts on the gearwheels 5, for example a mechanical drive coupled to a drive source. Not only can the pretension of the two slats 21 be changed, but slats 21 can also be brought into the threading position (indicated by dashed lines).
- a stationary thread eyelet 1 is attached to the base body and a pressure nozzle 25 is placed in front of it.
- a dashed line also indicates an air duct 26 which is elongated from the thread eyelet 1 to between the slats 21.
- Air guiding surfaces L in the form of webs 27 are provided on the mutually facing surfaces of the slats 21, which extend over an initial longitudinal region of the slats and converge, for example, in the direction of passage of the thread Y (FIG. 10).
- the webs 27 can be glued, soft elastic rubber lips that Do not affect the suspension properties of the slats 21.
- the slats 21 are adjusted to the dashed threading position according to FIG. 9 before an air stream blows the free thread end through the air guide channel 26 and between the air guide surfaces L of the slats 21.
- Fig. 9 drives A for the slats 21 are indicated, which are formed by magnets 28 fixedly fixed on the base body G.
- the magnets 28 are expediently proportional magnets whose magnetic force generated in the (metallic) lamellae 21 is proportional to the current applied.
- the magnets 28 can have a dual function. On the one hand, with a selected setting (the gear wheels 5) and the contact pressure of the plates 21 without changing the gear wheels 5 by the magnets 28, the contact pressure and the braking effect can be changed. However, the two magnets 28 are also able to bring the slats 21 into the threading position shown in broken lines without adjusting the gear wheels 5.
- 11 and 12 show another thread brake F ' ⁇ (multi-disc brake) which is suitable for automatic threading and which is distinguished from the previous embodiment, inter alia, by only one disc 36 as the active braking element B.
- an air guide channel 31 is formed in the extension of the stationary thread eyelet 11, which extends as far as the lamella 36 and ends with an oval mouth 40 in the wall 33 running approximately parallel to the lamella.
- the wall 33 belongs to a tubular part 30 of the base body G, which is continued on the side opposite the lamella 36 to the end of the base body G.
- a stationary elevation 35 in the form of a transverse bolt is attached in a recess 34, the contour of which protrudes only slightly beyond the contour of the channel 31.
- the bent end of the lamella 36 lies on the elevation 35 in the normal operating position (drawn in solid lines).
- the lamella 36 can be raised into the threading position (indicated by dashed lines).
- the underside of the lamella 36 with its curved end region forms an air guide surface L which, with the air guide surface formed by the curved contour of the elevation 35, guides the air flow from the channel 31 to the end of the base body G.
- the increase 35 is a passive counter braking element B G.
- a threading air nozzle 32 opens into the air guide channel 31 at an angle in the running direction of the thread Y in order to generate the air flow required for the automatic threading.
- An arm-shaped holder 29 is pivotable on the base body G about a transverse axis 38. With an actuating arm 39 the holder 29 can be pivoted about the axis 38.
- the pivot bearing is expediently self-locking. Since the lamella 36 is fixedly attached to the arm 29 at 37, the rotational position of the holder 29 determines the contact pressure of the lamella 36 at the elevation 35.
- the drive A is fastened to the holder 29 in the form of a magnet 28, with which both the contact pressure of the lamella 36 and thus the braking effect is modulated and the disk 36 can be moved into the threading position shown in dashed lines.
- a predetermined intermediate gap is provided between the magnet 28 and the lamella 36, which gap is matched to the range of the magnetic force.
- the lamella 36 and the magnet 28 are attached to the holder 29 in a fixed spatial association, so that the magnet 28 maintains approximately the same position relative to the lamella 36 regardless of the pivoting position of the holder 29 and its magnetic force is optimally effective.
- the thread Y is braked. As soon as the magnet 28 is excited to a certain extent, the lamella 36 is acted upon against its pretension; the braking effect decreases. If a thread break has occurred, which is detected, for example, by a thread break detector and is reported as a signal, then the magnet 28 is further excited until the lamella 36 is pulled into its threading position.
- the threading air nozzle 32 is pressurized with compressed air. A strong, directed air flow is created in the channel 31 and is guided from the thread guide surfaces L on the underside of the lamella 36 and on the top of the elevation 35 to the right end of the base body in FIG. 11.
- the resulting suction in the thread eyelet 1 pulls the free thread end held there for automatic threading into the channel 31 and threads the thread through it Thread brake F ' L.
- the magnet is de-energized again, to the extent that it corresponds to the desired braking effect, so that the lamella 36 rests against the elevation 35 again.
- the pressurization of the threading air nozzle 32 is interrupted.
- the holder 29 can also be adjusted accordingly about the axis 28, for which purpose a drive (not shown) is provided. If the thread breaks, this drive can also be used to bring the lamella 36 into the threading position by pivoting the holder 29.
- the threading air nozzle 32 could also be arranged instead of or in front of the thread eyelet 1. It is also conceivable to provide a plurality of nozzle outlets along the channel 31.
- the magnet 28 could also be arranged on the opposite side of the membrane 36 in the base body and act on the lamella 36 with compressive forces.
