Definitions

  • the invention relates to a thread storage and delivery device of the type specified in the preamble of claim 1.
  • the switching device controls the drive which is responsible for the addition of the thread supply. If the size of the thread supply is reduced to a minimum, the thread supply is increased again, if necessary up to a maximum size, when this drive is stopped again. It is also possible to carry out the control in such a way that the addition of the thread supply is always carried out in such a way that its size fluctuates between the maximum and the minimum value without ever reaching it. However, if the size of the thread supply reaches the minimum or maximum size value, this is a sign of a malfunction, whereupon the switching device not only stops the drive for the thread storage and delivery device, but also for devices that cooperate with it, possibly downstream devices.
  • a finger-like sensor fastened outside the storage body is usually used, the end of which is immersed in an axial recess in the storage body and is loaded by a spring.
  • the sensor either works with a switching device or has contacts that work with counter-contacts for signal generation. As soon as the thread supply becomes so large that it deflects the sensor to a certain extent, a signal is generated which interrupts the increase in the thread supply.
  • the disadvantage here is that the sensor exerts a certain load on the thread turns when pulling each thread turn is felt as a jerk.
  • the thread tension of the drawn thread not only remains small, but also constant, which is one of the main tasks of the thread storage and delivery device.
  • the thread When the thread is pulled off, it should form a so-called balloon, if possible, which is prevented by the sensor which engages from the outside. Furthermore, it is unfavorable that the sensor or its suspension is to be set to the respective thread type or characteristic and that the sensor must also be adjusted depending on the thread thickness, for which a comparatively large amount of effort is required. For this reason, more and more people have switched to optical or opto-electronic sensors, which are able to scan the thread size without contact. In these, the directed light beam is reflected by a mirror surface fixed to the storage body and then scanned, for example, for its intensity. It is very difficult to permanently generate a strong and significant and reliably scannable signal.
  • the invention has for its object to provide a thread storage and delivery device of the type mentioned, in which the control or monitoring of the size of the thread supply is achieved without interfering influence on the thread withdrawal from the storage body.
  • the sensing element does not directly actuate any contacts or switching devices, so that it imposes a barely perceptible load on the thread. However, the sensing element detects a change in position of the sensing element without contact and generates the reaction signal which actuates the switching device, since the movement of the sensing element determined by the sensing element signals that the thread supply has become too large or too small.
  • the proximity initiator determines, for example on the basis of an influence on the field generated by him / the change in position of the sensing element that has taken place, and generates the signal.
  • Commercial proximity initiators respond extremely sensitively to changes in position associated with changes in distance and can easily stand so far from the surface of the storage body that they do not hinder the thread movements. Other electrically or magnetically conductive elements that are not directly in the sensing range are ignored.
  • the embodiment of claim 3 is also expedient because a metal leaf spring can be easily bent into the optimum shape in each case at a low weight, the restoring force permanently applies itself and is easy to attach. Together with the small and light proximity initiator, this creates a reliable, light, and space-saving sensing unit.
  • an embodiment is also expedient, as indicated in claim 4. Every change in the position of the sensing element requires a change in the position of the magnetic field, which the sensing element detects as a change in the field strength and is used to emit a signal.
  • This axis, about which the sensing element pivots, can be relatively close to the surface of the storage body, so that the mass of the sensing element is concentrated around the axis, together with the permanent magnet, which benefits the easy mobility of the sensing element. It is favorable that the tilting movement leads to a defined tilting movement of the magnetic field of the permanent magnet, which is felt by the sensing element with a sudden and relatively strong change in the strength of the magnetic field.
  • the respective tilt axis for the end can be arranged so that a large lever arm and thus a small force for moving the end can be achieved.
  • an embodiment as claimed in claim 7 is also advantageous.
  • Such a spiral spring is durable and can be loaded with a uniformly low resistance and has the advantage that it can simultaneously secure the position of the sensing element in the storage body.
  • tension spring takes over the resilient property of the spiral spring and ensures that the sensing element returns to the one position in which it protrudes over the surface of the storage body when the thread supply has released the sensing area.
  • the sensing element is not acted directly in the sense of a reset, but again only in a magnetic manner, which can easily be accomplished in such a way that the initial force for deflecting the sensing element from one position is very low, which is favorable for the thread turns.
  • the sensing element is displaced in a linear direction by the thread turns, the weakening of the magnetic field strength occurring then also being determined by the sensing element and used for signaling is pulled. It is favorable here that the sensing element can be accommodated in a small opening in the storage body, which can be shielded well against contamination.
  • sensing element has no fixed tilt axis in the storage body, but is held in an unstable equilibrium position by the restoring force, from which it can be rolled into another, possibly stable, equilibrium position under the action of the thread turns.
  • the oval shape of the disc then ensures that the sensing element no longer protrudes beyond the surface of the storage body in the second position.
  • an embodiment is also expedient, as can be seen from claim 12.
  • the step in the guideway ensures that the sensing element protrudes above the surface in one position and no longer protrudes above the surface in the other.
  • the measure of claim 14 is also important so that the thread turns can easily move the sensing element from one position to the other.
  • a further, particularly expedient embodiment emerges from claim 16. Thanks to the polarity of both The tilting element is slave magnetically forced to follow a tilting movement of the sensing element.
  • the tilting element can easily be designed so that it actuates a switching device or cooperates with an optoelectronic switching element protected against dirt, which would not be possible for the sensing element.
  • the sensing element gives, so to speak, the magnetic pulse for the tilting element, which causes it to move with which a signal is generated.
  • FIG. 17 is also particularly expedient because it eliminates the need for its own spring or permanent magnet to set up the sensing element and the magnetic effect between the two permanent magnets of the sensing element and the tilting element is used to generate the mutual force.
  • sensing element is not only simple and inexpensive to manufacture, easy to accommodate in the storage body, but also allows a quick response to contact with a thread turn to be achieved.
  • the penetration of dirt, which may impair the function of the sensing element, can be effectively prevented according to claim 1 9.
  • An embodiment is almost completely maintenance-free, as can be seen from claim 20, because the recess receiving the sensing element is hermetically sealed from the outside, so that no contamination can impair the function of the sensing element.
  • each sensing element thus monitors a limit on the size of the thread supply and a total of two Signals can be generated, which can be further processed in analog or digital form and used to control various devices.
  • claim 22 specifies a structurally simple embodiment in which both sensing elements are formed on the leaf spring.
  • the change in position of the sensing element is used to also shift a light beam reflected by the sensing element, which comes from a light beam directed onto the sensing element.
  • a very powerful light beam can be used and that, due to the displacement of the reflected light beam, a very strong signal is produced because the receiver does not detect the change in the intensity of the light intensity of the reflected beam, which is relatively weak for certain reasons , as before, but clearly differentiates between the presence of a strong reflected light beam and its absence. For this reason, this optical device is much less sensitive and reliable than previously known.
  • the receiver is positioned at a point along the path through which the reflected light beam travels when the sensing element changes position. At one point in the movement of the sensing element, the receiver receives the light beam while it is not being acted upon over the rest of the movement path.
  • the signal that can be generated is significant and strong.
  • Another, alternative embodiment stands out by the measure 'from claim 25.
  • the light beam is applied to the receiver. If the sensing element moves out of this position, the receiver receives no reflected light beam and is clearly informed of the change in position that has taken place.
  • the feature of claim 26 is also important, because with the respective choice of the direction of the light beam, which is reflected by the sensing element, an optimal control behavior can be selected, or because the designer of the device changes in the assignment of the individual interacting components in a larger one Area is enabled.
  • a thread storage and delivery device 1 is shown schematically and in partial section, which has a lower housing part 2 with a lateral holding arm 3, to which a carrier 4 is attached with a thread take-off eye 5.
  • the lower housing 2 contains a drive motor (not shown) for a tubular thread winding member 6, which rotates with a drive shaft 7 which passes through the device 1 in the axial direction.
  • a drive motor (not shown) for a tubular thread winding member 6, which rotates with a drive shaft 7 which passes through the device 1 in the axial direction.
  • two halves 10 and 11 of a drum-shaped storage body are rotatably mounted in separate bearings 8 and 9 with mutually inclined axes of rotation (not shown), which have interlocking rods 12 and 13 which define an approximately cylindrical surface 15 of the storage body.
  • the thread designated 27 is fed through the thread winding member 6 and wound in the tangential direction onto the surface 15, where it forms the thread supply 26 with several turns, from which the thread then passes over a head part 22 of the storage body or its thickened edge through the thread eyelet 5 is withdrawn again.
  • a Maximum sensor 18 and a minimum sensor 19 are arranged, with which the respective size of the thread supply 26 can be scanned.
  • sensing elements 20 and 21 are aligned with the sensors 18 and 19, which scan the respective position of each sensor and generate signals therefrom, with which the drive motor in the lower housing part 2 is started or stopped, for example to increase the thread supply 26 wind up more thread or stop winding the thread.
  • a magnet 24 is fastened in the head part 22, which is aligned with a magnet 23 accommodated in a holder 25. Between these magnets 23 and 24, a holding force is built up which keeps the storage body still, so that the drive shaft 7 rotates in it and thereby excites the two halves 10 and 11 of the storage body to the feed movement.
  • a filler 14 is also contained in the storage body, which has to prevent the ingress of contaminants into the cavity of the storage body and to the bearing points 8 and 9.
  • the thread supply 26 should have a certain size, which changes depending on how much new thread the thread winding member 6 winds up and how much thread is drawn off by the thread take-off eye 5.
  • the size should fluctuate between a maximum and a minimum value, both of which must not be exceeded. Accordingly, in FIG. 1 the minimum value sensor 19 is actuated, which indicates that the thread supply is larger than the minimum value, while the maximum sensor 18 is not actuated, which indicates that the thread supply 26 is correctly still smaller than the maximum value.
  • the maximum and minimum sensors 18, 19 are formed by sensing elements, which are the two ends 65, 65 'of an integral metal leaf spring 66.
  • the metal leaf spring 66 is fixed with a flat base part 67 in the recess 16 with a screw 68 easily replaceable.
  • Vertical legs 71 extend from the base part 67 in the direction of the surface 15 of the storage body, the ends 65, 65 'of which are bent laterally in such a way that each end 65, 65' projects above the surface 15 without the contact pressure of the turns 27 .
  • the end 65 ' is bent relative to an intermediate part 70 in such a way that it does not lie above the surface 15 in the unloaded state, but rather forms an oblique run-up surface for the turns 27, while in the loaded state it is pushed into the depression about a tilt axis 69' (Fig. 2a) that the intermediate part 70 is approximately flush with the surface 15.
  • the tilt axis 69 'of the end 65' could also lie at the lower end of the rear leg 71 in the transition to the base part 67.
  • the other end 65 has its tilt axis 69 either - as shown - in the transition from the right leg 71 to the base part 67 or in the transition from the end 65 to the right leg 71.
  • proximity initiators which generate an electromagnetic or an eddy current field which is influenced by changing the position of the electrically conductive sensing element 28', 28 "for signal generation.
  • proximity initiators are commercially available and are available in different sensitivity levels. They also work flawless if there are other metallic elements nearby. Therefore, the one-piece design of the leaf spring 66 does not impair the proper operation of both initiators 20 ', 21'. However, the two sensing elements 28 ', 28 "could also be formed by separate leaf springs.
