Definitions

  • the invention relates to a creel for coils with thread-like material, in particular yarn spools, of which the thread is drawn off laterally with a winding machine with a braking device that is separate for each coil brake element mounted on the gate, which against one Coil bobbin or a part rotatable therewith with an adjusting device is pressable, the braking element via a intermediate spring acted upon, e.g. US-A-3 107 878.
  • weights can be up to 20 kg.
  • Such Weights are with conventional braking devices, such as. the one described above, not slowing down quickly enough, so that the thread end of the wound thread can still be reached between the gate and the winding machine can, if the coulter is to be kept taut.
  • the braking devices are not able to to brake heavy bobbins so that the thread group is tensioned remains.
  • the take-off speed must be reduced so that both of the above criteria are met can and therefore can only pull speeds with such gates from 80 to 120 m / min can be achieved.
  • the invention is based on the object to increase the production of the creel that the Withdrawal speeds are increased, but in the case a thread break both the end of the torn wound up Thread can be reached before the winding machine must be able to fix the thread break by thread knotting, how the thread group can be kept taut, around tangle of threads before restarting the winding machine avoid.
  • the adjusting device has an adjustment stop on the braking element then acts rigidly when it is from the spring with predetermined Force is applied.
  • a parallel effective adjustment stop of the adjustment device available is independent of the intermediate spring of the Adjustment device works.
  • the voting is so that the adjustment stop only comes into effect when the braking element is acted upon by the spring with a predetermined force is. This can ensure that the Adjustment device via the braking element in a predetermined Force area contributes to the tension of the thread, whereby the range can be determined so that the normal winding operation is mastered.
  • the rigid-looking adjustment stop is only used when the normal thread tension generation serving force must be exceeded, by the rigidly acting adjustment stop of the adjustment device while eliminating the action of the spring to a rapid deceleration of the coils.
  • the rigid one Adjustment stop can also be brought into effect if the force used to generate normal thread tension the spring has not yet been reached, e.g. when starting the Winding machine.
  • the running speed can increased from 80 to 120 m / min to 160 to 200 m / min as experiments have shown.
  • the coil creel is expediently designed in such a way that that the braking element has a flat brake pad that is tangential to a brake disc forming the non-rotatable part of the Coils.
  • the tangential contact of the brake pad results defined friction ratios that lead to a flawless Brake the coil.
  • the creel can be designed so that the Braking element from a rigid bearing piece and one on it elastic brake pad exists.
  • the rigid bearing piece can the braking element of matched components the adjustment device can be securely clamped and the elastic brake pad ensures a finely dosed or by Setting tolerances largely independent setting of the Braking force during normal winding operation.
  • the creel is developed so that the lever bearing the brake element is a two-armed Lever is on one arm of the braking element and the other arm engages the spring.
  • the dimensioning of the Arm lengths can be adjusted so that with a comparative weak and consequently easily adjustable A strong braking effect is achieved when the spring Arm for the braking element short and the arm for the spring long is.
  • the adjustment stop can also result one long arm and the other short arm a very strong braking effect can be achieved.
  • the creel has a variety of braking devices has, each used for one of the many coils , the creel can advantageously be further developed be that the spring is acted upon by an actuating rod is on the springs of other braking devices of other coils, each adjustable as needed, attached. It is consequently possible to control the creel centrally, for example by means of a single hydraulic actuating cylinder, who attacks the control rod.
  • the springs are adjustable on the adjusting rod attached so that by changing the attachment points can be achieved that all coils with the same Braking force are applied.
  • the creel is designed so that the control rod and / or the stop rod with a gate-fixed adjustment handwheel or a gate-fixed control cylinder are coupled.
  • the handwheel With the help of the handwheel a manual adjustment of the braking effect can be achieved for normal winding operation.
  • the control cylinder can be used in this sense, when it hits the control rod.
  • the control cylinder can but can also be used for a quick stop, when the spring is actuated by the actuating rod is run over, or if the stop rod from the control cylinder is applied.
  • the creel can be structurally advantageous be designed that the coils on vertical gate bars are stored, and that the bearing of the rigid lever are attached to these gate bars.
  • a simple one is enough vertical gate bar to both multiple coils, as well also store the associated braking devices.
  • At the same time is a high stability of the creel or a Construction achieved in the interaction of the braking device and the coil only slightly of tolerances and Elasticities of structural parts is affected.
  • the creel consists of a large number of winding positions with coils 10.
  • the construction of the creel is not shown in detail and can largely be arbitrary.
  • vertical gate bars 24 which are designed, for example, as square hollow tubes are.
  • Support axes 27 are arranged on these gate rods 24. According to Figure 4, a support axis 27 extends horizontally on both sides of the gate rod 24 and forms a double winding unit.
  • the support shaft 27 is fastened by Screwing on the gate rod 24 by means of a retaining clip 28 and fastening screws 29.
  • Each support axis is 27 close to the gate bar with a one with a coil 10 a non-rotatable Part 14 forming brake disc provided on the Support axis 27 is rotatably mounted.
  • the part 14 has an attachment end 14 ', which is extends parallel to the load axis. On the push-on end 14 ' one end of a coil sleeve 10 'of a coil 10 is plugged on, the other end of which is held by a push-on cap 33, which is firmly connected to the outer end of the axle sleeve 32.
  • the coil 10 has the one shown in FIG. 4 in cross section Winding from which a thread 11 is drawn off tangentially, as can be seen from FIGS. 1 to 3. There is a Deflection of the thread 11 around a thread deflection roller 21, which 4 over the entire width or length of the coil 10 and each extends somewhat beyond the ends, so that the thread 11 oscillate along the length of the bobbin can and is still rolling.
  • a braking device is assigned to each winding unit, which has a braking element 12 that with an adjustment device 13 can be pressed against the part 14.
  • the braking element 12 has an elastic brake pad 17 on the outer circumference of the Part 14 or the brake disc is tangential.
  • a rigid lever 18 which is pivotable at the bearing 19 is mounted on the vertical gate rod 24.
  • the lever 18 is a two-armed lever with a very short, the braking element 12 bearing arm 25.
  • the arm 25 is pot-shaped, around the rigid bearing piece 12 'of the braking element 12 grasp and hold, for example, form-fitting.
  • the flat brake pad 17 is attached and for example designed as an elastic cushion.
  • the lever 18 has a second, long arm 20, at the outer end 20 ' the thread deflection roller 21 is arranged.
  • the arm 20 extends practically over the entire Diameter of the coil 10, but hardly more. Consequently the result is a compact design in which the maximum outer diameter of the coil 10 or the outer diameter the maximum length of the braking device or their adjusting device 13 in the display level certainly.
  • a spring 15 engages in the vicinity of the thread deflection roller 21 with one end, the other end e.g. with a clamping ring 34 an adjusting rod 22 is attached, which is transverse to Gate bar 24 extends horizontally.
  • the actuating rod 22 is arranged practically parallel to the spring 15, which as a tension spring is trained and when acted upon by the actuating rod 22 the lever 18 which can be pivoted about the bearing point 19 e.g. from the position shown in Fig.1 to the in Fig.2 position shown can pull.
  • the brake pad 17 pressed against the outer circumference of the part 14 and the bobbin rotating due to the withdrawal of the thread 11 10 is braked because the part 14 with the coil sleeve 10 ' sufficiently frictionally connected via a clamping ring 35 is.
  • the spring 15 can fine braking the coil 10 take place so that the thread tension in the thread 11 in the desired Way is achieved. So that all winding units of the Coil gate can be applied in the same way, the The clamping ring 34 on the adjusting rod 21 can be adjusted as long as until, for example, a measurement of the thread tension of the thread 11 of all winding units results in the correct pre-adjustment.
  • the adjustment of the thread tension via the adjusting rod 22 can be done manually.
  • 4 shows an adjusting handwheel 23, that is coupled with a threaded bush 35 with a threaded rod 36 is, which engages a coupling piece 37 on the two adjusting rods 22 are attached.
  • the adjusting handwheel 23 is opposed to the threaded rod 36 the force of the springs 15 attracted, so that the braking effect is increased on the coils 10, or the threaded rod 36 is released so that the springs 15, the rods 22 in the sense a lower braking of the coils 10 can adjust.
  • the adjusting handwheel 23 is fixed in a frame but is rotatable, as can be seen from the supporting structure 38 results.
  • On this support structure 38 is a control cylinder 26 attached, the piston rod 26 'via a threaded rod 39 is connected to the threaded sleeve 35.
  • An application of the control cylinder 26 therefore results in a corresponding one Adjustment of the coupling piece 37 and a corresponding one Actuation of the springs 15, which is therefore excited or can be relaxed to with the adjustment device 13 brake the coils 10 more or less strongly.
  • Adjustment stop 16 is attached, e.g. by screwing according to Fig. 4.
  • the adjustment stop 16 is angular and reaches behind the long arm with its one angle leg 20 of the lever 18 in the vicinity of the thread deflection roller 21 or Articulation point of the spring at the end 20 'of the long arm 20.
  • the Adjustment stop 16 is rigid and then comes to Effect when the braking force acting on the coil 10 should be stronger than the normal 15 by the spring Braking or generating the tension in the thread 11 is required becomes.
  • the loading can the actuating rod 22 by the control cylinder 26, with which the braking force with normal thread take-off is produced.
  • the spring 15 is almost completely extended or until to extend to the length required to with her to generate predetermined braking forces on the coil.
  • The can be undesirable in the sense of a short-term quick stop because this movement takes time during the the coils 10 move practically unchecked and at corresponding thread lengths at high thread take-off speeds unwanted to be handled.
  • the adjustment stop 16 is then in all Positions of the control rod 22 in the immediate vicinity of the arm 20 of the lever 18 arranged. So the stop bar becomes parallel to the actuating rod 22 to the same extent as this, when the creel is operating normally.
  • the stop rod can be independent of the control rod 22 are applied and immediately one accordingly quick adjustment of the lever 18 with a correspondingly stronger Decelerate the coil 10 without first the spring 15 should be pulled out fully.
  • the stop bar is therefore This is particularly advantageous when starting up the winding machine.
