Definitions

  • the invention relates to a bell spinning machine according to the preamble of patent claim 1.
  • an auxiliary drive is provided for the bell-shaped thread guide members, which initially enables the machine to start up faster (acceleration of the relatively sluggish thread guide member) and, if necessary, can also help to overcome the friction during operation.
  • speed of the thread guide member it has been proposed in DE-A-3046180 to arrange whorls on the thread guide members which are in contact with a drive belt and each are coupled with the associated thread guide member via a freewheel.
  • the thread guiding member which has a relatively large inertia, shows the tendency to continue turning longer than the spindle.
  • the object of the invention is now, in a bell spinning machine of the type mentioned, the auxiliary drive, which when the machine starts Drives thread guide elements to be designed in such a way that when the machine is switched off, the thread guide elements are braked more quickly - and with the same delay as the spindles. It should also be possible for the speed of the thread guide members to adapt to the growing yarn package diameter during operation.
  • the spindle drive element and the belt are expediently driven by a common drive at speeds which are in a fixed relationship to one another, in such a way that the belt runs somewhat slower in operation than the circumference of the whorls on the thread guide elements entrained by the thread.
  • the thread guide members are then slightly braked by the belt during operation by means of friction, the braking force depending on the adjustable pressing force exerted on the belt.
  • the pressing force is then increased, so that the thread guide members, despite their relatively large inertia, run out almost synchronously with the belt and come to a standstill.
  • the device for pressing the belt can be implemented in a simple manner with pressure rollers which can be moved transversely to the belt and are moved by a common control element.
  • the control element can expediently be a control rod that can be moved parallel to the belt between two end positions.
  • the bell spinning machine shown has a spindle bank 2, which is guided vertically displaceably on columns 1 and carries a row of spindles 3.
  • the spindles 3 are each rotatably mounted about a vertical axis in a bearing 4 arranged on the spindle bench 2 and are driven by a drive element, e.g. from a drive belt 5, which rests against a whorl 6 of each spindle 3, or instead from individual drive motors.
  • Each spindle 3 is assigned a bell-shaped thread guide member 7 which can be rotated about the spindle axis.
  • a thread 8 coming from a drafting system enters the thread guide member 7 from above, then passes through a guide opening at the lower edge of the thread guide member 7 and runs to the bobbin sitting on the spindle 3.
  • the thread guide members 7 are rotatably mounted in the upper neck region of the same in bearings 9 in a bracket 10 carried by the columns 1 and carry whorls 11, against which a belt 12 rests, which is pressed against the whorls 11 by a pressing device with an adjustable force.
  • the pressing device contains pressure rollers 13, each of which bears against the belt 12 between two adjacent whorls 11.
  • a pressure roller 13 is sufficient as shown for two whorls 11; but there could also be more pressure rollers.
  • the bearing 14 of each pressure roller 13 is in each case fastened to a flexible plate 15, i.e. a plate with a flexible, elastic section, the end of which is fastened to a stationary mounting rail 16. In this way, each pressure roller 13 is movably guided transversely or approximately transversely to the belt 12.
  • a common control element in the form of a control rod 17 which can be displaced parallel to the belt 12 is provided.
  • a cam 18 is mounted on the control rod 17 for each of the plates 15.
  • the plates 15 are inclined to the belt 12 and thus represent a surface inclined to the belt 12, and one of the cams 18 engages on their rear surfaces. If the control rod 17 is moved with the cams 18 in the direction of arrow P parallel to the direction of travel of the belt 12, the pressure rollers 13 are thereby moved against the elastic bending force of the plate 15 towards the belt 12 and press the latter more strongly against the whorls 11.
  • the control rod 17 is moved by a double-acting cylinder-piston unit 19. The displacement of the control rod 17 is limited in both directions by an adjustable stop 20 and 21, respectively.
  • the spindle drive belt 5 and the belt 12 are driven by a drive, not shown, at speeds which are in constant relation to one another, in such a way that the linear speed of the belt 12 is set somewhat less than the tangential speed of the peripheral surfaces of the whorls 11, which sit on the thread guide members 7 dragged by the threads.
  • the belt 12 therefore exerts a small braking force on the whorls 11 due to friction.
  • the magnitude of the braking force depends on the force with which the pressure rollers 13 press the belt 12 against the whorls 11.
  • the control rod 17 stands during the spinning as drawn in its lower end position in FIG.
  • the cylinder-piston unit 19 is also actuated when the drive for the belts 5 and 12 is switched off and, if necessary, braked, and the control rod 17 is thereby adjusted, shifted or moved sufficiently quickly into its other end position at the end stop 21.
  • the cams 18 move the pressure rollers 13 further towards the belt 12 via the inclined plates 15. The force with which the belt 12 is pressed against the whorls 11 becomes so great that the belt 12 has the braking force required to brake the thread guiding elements 7 - by friction or even by eliminating the slippage between the belt 12 and whorls 11 - on the Whorls 11 can transmit.
  • each pressure roller 13 could be carried by one arm each of a two-armed lever pivotally mounted in the mounting rail 16, the other arms of these levers being articulated on a control rod which can be moved parallel to the belt 12.
  • the bearings 14 of the pressure rollers 13 could be guided displaceably in the carrier rail 16 transversely to the belt 12 and supported on a ramp arranged on the displaceable control rod 17 and inclined to the belt 12.
  • the cams 18 can also have a wedge shape.
  • the belt 12 can of course also only be used for starting and stopping the machine.
