Definitions

  • the present invention relates to a winding machine for the simultaneous production of at least two coreless thread bobbins according to the preamble of patent claim 1.
  • coreless thread spools also called bobbins.
  • Such bobbins are produced on winding machines with overhung spindles.
  • the threads are wound up by a delivery spool directly on the spindle with the interposition of a thread brake and during the winding it changes over the stroke that determines the length of the thread spool.
  • a secondary shaft is driven synchronously, with which one ejector is driven by the spindles to repel the thread spools.
  • the ejectors are connected to the auxiliary shaft via couplings, and the couplings are activated as soon as the bobbins contain the desired amount of yarn.
  • the device for confirming the threads on the thread spools is also driven by the auxiliary shaft, which continuously rotates, although it is only required for a short time each time the thread spools are ejected.
  • the object of the present invention is to create a winding machine with less maintenance effort and compared to the known higher and variable winding speed lower manufacturing costs.
  • the inventive design of the drives of the two spindles not only allows higher speeds and thus a higher winding performance of the machine, but at the same time the noise development is significantly reduced despite the increased speed.
  • the drive for confirming and ejecting the full bobbins is directly connected to the main shaft and is switched on briefly by a clutch.
  • the actuation kinematics and the ejection device are triggered by feeler elements which individually detect the diameter of the thread spools. After a precisely adjustable setpoint has been reached, the keys emit a signal to release the clutch.
  • the clutch can be operated pneumatically or electrically.
  • the new one also has fewer parts and the lower weight means lower freight costs.
  • the noise generated by lower vibrations is much smaller.
  • the machine can be operated essentially maintenance-free because the duty cycle of the power take-off and the other machine parts caused by their movements are subject to wear and tear, only have a duty cycle of approx. 3% of the machine running time.
  • the parts that are in continuous operation are lubricated for life and designed to be maintenance-free.
  • the smaller number of parts and a simplification of the power take-off for confirming and ejecting the finished bobbins make it possible to reduce the engine output and thus also the energy consumption by a third compared to the known machine.
  • the individual parameters of the machine can be set reproducibly using scales. This not only enables reproducibility, but also a short setting and changeover time when changing the thread material and diameter of the bobbins.
  • the use of a frequency converter to adjust the speed of the machine has a positive effect on the energy balance and enables the speeds to be ramped up and down very gently. Controlled lowering enables the run-down time of the parked machine to be determined precisely, and the CE worker protection regulations can thus be fully met.
  • the parallel operation of the machine allows the simultaneous production of largely identical thread spools. With the infinitely variable eccentricity adjustment for the connecting rod of the laying finger drive, the stroke can also be adjusted and adjusted while the spool is being built up. It can be used to individually manufacture bobbins adapted to the properties of the thread to be wound and the needs of the consumer.

  • the drive pulley 19 on the main shaft 17 lies behind a gearwheel 21 which meshes with a smaller gearwheel 25 mounted on a first spindle 23.
  • the spindle 23 is supported by roller bearings 27 in the bearing plates 9 and 10 and ends in a flying manner on the front side A of the machine 1.
  • On the main shaft 17 there is also a freely rotatable but axially displaceable worm 29.
  • the countershaft 31 carries cams 33 and 34 at one end, which serve to drive a kinematics mechanism (not shown) for confirming the incoming thread 35 at the end of the winding process and an ejection device 39.
  • the kinematics are known from the Casati Carlo AG dishwasher mentioned at the beginning, so they are not described in more detail.
  • a synchronous shaft 44 which is perpendicular to the main shaft 17, there are two pinions 37, which are intended to drive the ejector 39 for the axial ejection of two thread spools 41 generated on the spindles 23 synchronously.
  • the ejector 39 are axially displaceable in the bearing plates 9 and each have an ejector 43 at their front ends, which carry a fork or an eyelet 45, which at least partially surround the spindles 23 behind the thread spool 41.
  • the rear end of the ejector 39 is designed as a toothed rack 47, which also takes over the axial guidance of the ejector 39.
  • the rack 47 is in engagement with the pinions 37 via a joint lever 42 and an ejection lever 46 with the cam plate 34, which ensure the synchronization and straight running.
  • a second spindle 23 ' is rotatably mounted as a mirror image of the first in a bearing 27' in the bearing plates 9, 10 and is driven synchronously by the first spindle 23 by a toothed belt 51.
  • the clutch disc 54 is non-rotatably placed on the main shaft 17.
  • a pneumatic or magnetic drive can be used as the clutch actuating element 55, which generates the necessary stroke of a few tenths of a millimeter and the necessary force and the contact between the Clutch disc 54 and the screw 29 is maintained for a short time.
  • the worm 29 is rotated and the auxiliary shaft 31 is driven.
  • the direction of rotation of the auxiliary shaft 31 is selected such that the axial thrust force F a of the worm 29 which arises during operation supports the force for actuating the clutch.
  • the pneumatic or magnetic drive can therefore have a correspondingly low power consumption.
  • a bearing 57 eccentrically mounted to the axis of the main shaft 17 and carries on its outer ring a connecting rod 59 which is connected via a joint head 61 to a pivotable boom 63.

  • a drive 194 pneumatic piston-cylinder unit 194 or an electric linear drive / servo motor (not shown).
  • the connection between the drive 194 and the lever 193 takes place via an appropriately designed joint 195, which deflects the lever
  • a damping element 196 is advantageously placed on the piston rod 198, which enables a smooth adjustment of the eccentricity on the eccentric bearing 157.

  • the operation of the dishwasher 1 is explained below using the thread bobbin construction on a machine equipped with two spindles 23.
  • the thread 35 runs through a first thread brake 81 to the spindle 23 and then to a second thread brake 82.
  • the first thread brake 81 can be a disk wrapped in the thread 35.
  • the second thread brake 82 also provides one
  • Thread store which compensates for the pull-off speed of the incoming thread 35 which varies over the stroke of the bobbin 41.
  • the speed of the incoming thread 35 changes because the path length of the thread between the second thread brake 82 and the surface of the bobbin 41 changes due to the traversing of the thread and at the same time the winding speed remains constant during a thread stroke.
  • Differences in speed are also greater if the coil has a barrel shape rather than a cylindrical shape.
  • the path from the second thread brake 82 to the bobbin ends is in each case significantly greater than to the center of the bobbin 41, where it has the largest diameter and is also closest to the second thread brake 82.
  • Two pairs of deflecting fingers 84, 86 connected to one another in an articulated manner can be used as the second thread brake 82, which deflect the thread 35 in a zigzag shape when the take-off speed decreases.
  • the thread 35 is moved parallel to the spindle axis by a stroke h by the laying finger 69.
  • the traversing also called laying, is carried out by the eccentric drive with the eccentric bearing 57, 157 and the overdrive by means of a connecting rod 59, 159 which is driven directly by the main shaft 17, 117.

  • a valve 85 is opened and the worm 29 is thereby pressed axially in the direction of arrow P on the main shaft 17 against the clutch disc 54 and coupled to it in a friction-locked manner.
  • the auxiliary shaft 31 is set in rotation via the worm wheel 25. This rotation is shown by a not shown Triggered switch that actuates the valve 85 and built up the frictional contact between the screw 29 and the clutch disc 54 with the pneumatic drive.
  • the angle of rotation of the worm wheel 30 is limited to 360 degrees.
  • an angle sensor is placed on the shaft 31, which actuates the valve 85 after the 360 “rotation. This rotation activates the non-illustrated device and the ejection device 39. The latter is activated by the cam plate 34, the ejection lever 46 and the articulated lever 44 actuated, which drives the toothed racks 47.
  • the repeller 43 on the front end of the ejection element 39 pushes the full thread spool 41 beyond the end of the spindle 23 and the construction of a thread spool 41 begins anew.
  • the two thread spools (the ejected and the in Structure 35) connecting thread is cut by a knife, not shown.
  • an infinitely variable stroke or laying length for the thread 35 takes the place of a stroke that is predetermined by the eccentric bearing 57.
  • the eccentric bearing 157 is adjusted radially to the axis of rotation X of the main shaft 187 by axially displacing the adjusting rod 187.
  • the distance between the axis of the eccentric bearing 157 and the axis of rotation X of the main shaft 117 can be set before the start of the coil build-up and during the coil build-up stay the same.
  • the stroke axial laying length of the thread over the bobbin
  • bobbins of different geometry and the properties of the thread 35 or the specifications of the intended use can be adapted. It is therefore possible to create cylindrical, conical or barrel-shaped coils. Not only can the diameter course of the coil be adjusted in the axial direction, but also the formation of the end faces, for example a slightly conical course.
  • the eccentric bearing 157 is displaced radially by the drive 194, which in turn is controlled according to the specifications by an electronic control, preferably a freely programmable control.
  • the ends of the ejectors 39 are each connected to their own linear drive 95, which makes the drive via the auxiliary shaft 31 superfluous.
  • the linear drives 95 are activated after the knotting / confirmation of the thread end on the bobbin 41 has been completed.
  • Pneumatic drives or electromagnetic drives can be used as linear drives 95.
  • a bezel 81 comprising a roller bearing 83 and a roller bearing holder 85, is arranged in front of the coil 41 that is building up.
  • the inner ring 87 of the roller bearing 83 has an inner diameter that is a few hundredths of a millimeter larger than the maximum diameter of a full coil 41.
  • the roller bearing 83 is carried by the roller bearing holder 85, which can be easily opened to accommodate one roller bearing 83 in each case. After completion of the coil build-up of a coil 41, this is pushed forward by the ejector 39 on the spindle 23 so that there is enough space to be able to build a new coil 41. The spool pushed forward now lies almost exactly centered within the bezel 81 and is held concentrically by it. As a result, vibrations of the spindle 23 can be reduced to a minimum even at very high speeds and, if necessary, unevenly constructed coils 41.
