Definitions

  • the invention relates to a device for variable braking of running threads, wires or the like, in particular for use in weft insertion on weaving machines. And a method for operating such a thread brake.
  • a thread brake is known from French patent application FR-A-23 75 366.
  • the thread is passed between two brake parts that can be brought together in a resilient manner.
  • One of the two brake parts is fixed and not resilient and the other brake part is cushioned and movable relative to the fixed brake part, so that the thread braking can be varied in its strength by a change in the spring tension achieved as a result of the movement.
  • the resilient brake part can also be spaced apart from the fixed brake part via a push rod via a push rod, so that an unbraked thread run can be achieved.
  • the problem with such a thread brake is that the spring force has to be relatively strong in order to brake the thread effectively.
  • the resilient braking part in order to achieve a free running of the thread, the resilient braking part must be completely lifted off the fixed braking part.
  • the spring of the resilient brake part must be at least partially relaxed. This results in relatively high displacement paths of the push rod driving the resilient element. There are also limits to such an arrangement with regard to the cycle times between braking and releasing the thread, since the relaxation of the spring can no longer follow high cycle frequencies.
  • the model for the invention was also the device for the different braking of running threads, which is not part of the prior art and was proposed in the non-prepublished utility model DE-U-91 13 430.
  • Such a device was also disclosed in document EP-A-0 524 429 belonging to the prior art according to Article 54 (3) EPC.
  • the device shown there already shows a fixed leaf spring which is acted upon by a cylindrical brake part.
  • This brake part is driven by an electric motor and has a cylindrical first section, the circumferential surface of which holds the spring in a pretension in the release position of the thread run.
  • a second section of the body has a peripheral section that is reduced in cross section. The thread runs between this second section and the leaf spring.
  • the thread is unbraked. After a further angular amount of further rotation of the rotatable body, the thread is acted upon by the non-reduced cross-sectional circumferential section of the second section, so that the thread-braking position is achieved, the thread being clamped between the leaf spring and the cylinder surface.
  • This device works in cyclical operation, with the drive motor running back and forth between two stops. In order to achieve a high clock frequency, the motor must both be driven at high acceleration and braked strongly. The use of mechanical stops for braking the motor, for example, is not optimal.
  • the object of the invention is to improve the performance of such a thread brake.
  • the device specified in claim 1 and the method specified in claim 6 are proposed.
  • the subclaims represent advantageous developments of the invention.
  • the resilient braking part no longer needs to be moved during operation to vary the braking.
  • Due to the essentially cylindrical first section of circular cross-section the spring element is constantly held in a prestress, which can be varied by adjusting means.
  • the second section which can also be brought into contact with the spring element, has in the circumferential direction at least one reduced cross-sectional circumferential section, which is reduced in cross-section to the extent that a window remains between the circumferential section and the spring element when it is opposite the spring element, through which the thread can be pulled off without braking.
  • the shaft of the electric motor can be gradually rotated further without mechanical stops having to be provided.
  • the stepper motor then only needs to be rotated by a corresponding number of steps, which is done by a corresponding number of switching impulses until the reduced cross-sectional reduced circumferential area is opposite the spring element and the thread brake position is reached.
  • a preferably curved leaf spring can serve as a spring element and at the same time as a thread guide.
  • Another preferred embodiment is one in which a plurality of circumferentially reduced circumferential surfaces are provided in the circumferential direction.
  • Circumferential areas not reduced in cross section are provided between these reduced-area circumferential surfaces.
  • a thread-free position occurs when a circumferentially reduced cross-sectional area is placed opposite the spring element, while when a circumferential area that is not reduced in cross-section is placed opposite, the thread is clamped between the counter-bearing and the spring element.
  • the embodiment of the invention in which the number of steps of the stepping motor corresponds to at least twice the number of circumferentially reduced cross-sectional sections is considered to be particularly advantageous. As a result of this configuration, the stepper motor needs Transition from a braking position to a release position can only be switched by a single step.
  • the number of steps of the motor is four. That means with every step the shaft of the stepper motor is turned through 90 °. In total, four steps are necessary to make one revolution of the shaft of the stepper motor.
  • the invention proposes in a further development that these circumferential sections are designed as flattenings arranged transversely to the radial. The transitions to the circumferential sections which are adjacent in the circumferential direction and are not reduced in cross-section could be rounded in order to protect the thread.
  • the stepper motor preferably has a magnetically polarized armature.
  • this armature can be formed from a permanent magnet. The orientation of the magnet is oriented radially to the axis.
  • this preferred stepper motor has an excitation coil running in the circumferential direction, which is subdivided into a number of partial windings which corresponds to the number of steps of the electric motor.
  • the annular coil core of the excitation coil Associated with the individual step positions of the electric motor, has opposite pole pairs. The armature of the electric motor is oriented between these pole pairs in accordance with the polarization of the excitation coil.
  • the excitation coil consists of an annular coil core with a total of four poles, each offset by 90 °, between which poles a partial winding is provided and if the armature is to be held between two of these poles by magnetic forces, the partial windings arranged between these two opposite poles are polarized in the same direction, so that a magnetization parallel to the armature magnetic field is built up. If the armature is now to be rotated one step, in this case by 90 °, the second pole pair lying transverse to the first pole pair is magnetized accordingly. Now the partial windings lying between these two poles are traversed by current in the same direction, so that a magnetic field aligned between these two magnetic poles is created.
  • the method for operating a thread brake in accordance with a device includes that with each step of the stepping motor, the thread brake alternates from a braking position into a release position, starting from a braking position corresponding to a step position of the electric motor, in which a non-reduced circumferential area is opposite to the spring element, in the subsequent step of the electric motor a cross-section-reduced area is brought opposite to the spring element.
  • the direction of rotation of the electric motor need not change after the transition from the braking position to the release position.
  • the electric motor can always turn in the same direction operate. This enables the armature to be magnetically bonded in any step position.
  • the body forming the counter bearing is rotated clockwise, step by step.
  • the device shown in FIGS. 1 to 5 has an engine block 24 which is formed on the outside with cooling fins 23.
  • the engine block is made of aluminum.
  • a motor shaft (not shown in FIGS. 1 to 5) emerges on one side of the engine block and carries an essentially cylindrical body 2.
  • the cylindrically shaped body 2 forms the counter bearing to a resilient tab 1, which thread F in the braking position between itself and the counter bearing 2 (Fig. 2) jammed.
  • the tab 1 is carried by a substantially U-shaped carrier plate 13 which is screwed onto the motor housing 24 with its bottom surface. The bottom surface of the carrier 13 is penetrated by the shaft of the motor.
  • Thread take-off opening 12 thread brake and thread inlet opening 21 lie almost on a straight line.
  • the above-mentioned pre-brake consists of two brackets 19, 20 which are spring-loaded against one another and which are each screwed onto square axes 18, 14.
  • the two tabs are screwed onto opposite surfaces of the square 14.
  • All three spring elements 1, 19, 20 have essentially the same rigidity and the same width, which cover the sections 4, 5, 8 of the body 2.
  • the section 8 is located between the sections 4, 5 of the body 2 which have a circular cross section.
  • the section 8 has two opposite circumferential sections 6, 7 with reduced cross sections in the circumferential direction. These circumferential sections are formed by flats which are arranged essentially transversely to the radial and which, in the transition region to the sections 10, 11 of the body 2 which are not reduced in cross section, have roundings 6 ', not shown in the drawings.
  • the cross-section-reducing circumferential sections 6, 7 form windows through which the thread can be drawn off without friction in the release position (cf. FIGS. 4 and 5).
  • the pre-brake consisting of the leaf springs 20 and 19 can be deactivated by appropriately adjusting the setting wheel 22 and pivoting the spring tabs 19, 10, namely by spacing the resilient tab 20 from the resilient tab 19.
  • the first section of the substantially cylindrical body forming the counterbearing consists of two circular sections 4, 5.
  • These circular sections 4, 5 have the effect that, even in a position according to FIGS. 4 and 5, the leaf spring 1 is in a prestressed manner Location remains.
  • the sections 4 and 5 run horizontally to the axis of rotation of the body 2.
  • a minimal change in the position of the spring 1 takes place in the braking position (see FIGS. 2 and 3), namely when the thread between one of the circumferential sections 10 or 11 not reduced in cross section and the Tab 1 is pinched.
  • the tab can be deflected by the thickness of the thread F. This is accompanied by a lifting of the tab 1 from the two Observe circular sections 4 and 5 in cross section.
  • the operation of the device is as follows: The thread runs from the inlet eyelet 21 through the brake and is drawn off by the draw-off eyelet 12 and fed to a loom or the like, not shown.
  • the resilient tab 1 is acted upon by the circumferential section 11 of the second section 8, which section is not reduced in cross-section, with the thread F being clamped in.
  • the thread is braked in this position. In this position, the thread is not drawn off, but is held at a certain thread tension only on the part of the thread insertion eyelet 21.
  • the body 2 is displaced by 90 °, as a result of which the thread's release position shown in FIGS. 4 and 5 is reached.
  • the thread can now be pulled out without braking.
  • the reduced-cross-sectional circumferential section 6 now has an opposite position to the leaf spring 1. Since the reduction in cross-section is many times larger than the diameter of the thread, it can be pulled off almost frictionlessly in the window formed by the reduction in cross-section. Because of the circular sections 4 and 5 which act on the tab 1 in this position, the tab 1 remains essentially in the same position.
  • stepper motor which is arranged in the motor housing 23 and is designated by the reference number 9. This stepper motor has a step number of four. This means that the shaft is rotated 90 ° with each step. Each step of the stepper motor thus corresponds to a transition from a braking position to a release position or vice versa.
  • the structure of the stepping motor 9 is shown schematically in FIG. 6.
  • the armature 44 which is designed as a permanent magnet oriented transversely to the axis of rotation, sits on the shaft 43, which is rotatably mounted in the motor housing.
  • the armature is surrounded by an annular core 30 of an excitation coil.
  • the excitation coil consists of a total of four partial areas each comprising an angle of 90 °.
  • Each sub-area has a sub-coil 31, 32, 33, 34 and an inwardly projecting pole 39, 40, 41, 42.
  • the partial coils 31, 32, 33, 34 are arranged between the four poles 39, 40, 41, 42, each offset by 90 °.
  • the ends of adjacent coils - for example those of the coils 31 and 32 - are connected to one another, the respective ends 31 "being connected to the ends 32 '.
  • the connecting position of the coils 31, 32, 33, 34 form electrical connection contacts 35, 36, 37, 38 out.
  • the corresponding electrical connections 35 and 37 are to be subjected to voltage current in such a way that a magnetic field aligned parallel to the magnetic field of the armature 44 is built up by the excitation coil.
  • the electrical connections 36 and 38 must accordingly be supplied with voltage current, so that a magnetic field builds up between the poles 40 and 42. If a corresponding magnetic field is then built up between the opposing poles 40 and 42, the armature 44 endeavors to orient itself in this magnetic field in accordance with its magnetization. As a result, the armature 44 makes a 90 ° clockwise rotation. The north pole and south pole of the armature are thereby shifted out of the orientation to the likewise opposite poles 39 and 41.
  • the armature is bound in the magnetic field built up by the excitation coil, the armature is prevented from rotating due to its angular momentum. As soon as the armature rotates beyond the equilibrium position parallel to the excitation magnetic field, the angle of the two magnetic fields causes the armature to return to its equilibrium position. This restoring force quasi forms an electromagnetic stop.
