Definitions

  • the member(s) are, in use, connected to a source of fluid under pressure and means are provided to cause the member(s) to be inflated or deflated, when winding has been interrupted due for example to a yarn or tape end break, the member being subsequently deflated or inflated to allow winding to recommence.
  • the means for causing inflation and/or deflation may comprise a standard stop motion associated with the winder and a valve device in the supply of compressed air or other fluid and connected to the stop motion.
  • the inflatable member is preferably a tube and it will be understood that a single tube could follow a tortuous path so as to act on all the packages on a creel but this would lead to a slight time lag in arresting some of the packages and although this lag would in all probability be so small as to be insignificant it is preferred to have a feed pipe positioned midway along the creel and inflatable tubes extending from either side of this pipe along each row of packages.
  • An inflatable member may itself be positioned so that on inflation it directly engages a package or a part of a rotating package support and in this case the member may be provided with a wear-resistant brake surface.
  • inflation of the member may be arranged to cause a separate wear-resistant brake member to engage the package or a part rotating therewith. On deflation the brake surface is moved clear of all rotating pans.
  • the inflatable member(s) may be so arranged and positioned that when inflated it raises the package supports clear of a braking surface, without affecting their free rotation but on deflation occurring the rotating packages or support assemblies are brought into contact with a braking surface.
  • the invention extends not only to a creel for use for exam- ;ple with a beaming machine, but also to-a method of braking packages mounted on a creel or the like comprising inflating, or deflating, an inflatable member and employing the inflation, or deflation, to cause the package or a part of its support rotating therewith, to engage or be engaged by a brake surface and further extends to a brake system for such a creel comprising one or more inflatable tubes designed to extend along a number of packages on a creel either a brake member or surface being provided for each package or the tube(s) being provided with a wear-resistant surface, and means to cause the tube(s) to be inflated, or deflated, on interruption of winding due for example to an end break.
  • FIG. 1 is a perspective view of a part of one embodiment of a creel in accordance with the invention
  • FIG. 2 is an end elevation corresponding to FIG. 1 showing the inflatable member, deflated
  • FIG. 3 is also an end elevation core corresponding to FIG. 1 but showing the inflatable member, inflated;
  • FIG. 4 is an end elevation of an alternative embodiment showing the inflatable member, deflated
  • FIG. 5 is a view similar to FIG. 4 but showing the inflatable member inflated
  • FIG. 6 is a side elevation of a part of the midsection of the creel of FIG. 1;
  • FIG. 7 is a side elevation of a part of the creel.
  • FIG. 9 is the electrical circuit
  • FIGS. 10 and10a are diagrams illustrating an end break detector.
  • a creel a part of which is shown in FIG. 1 comprises a framework of uprights 2 and horizontal channel members 4 mounting a number of supports for the packages 6 each support comprising a dish 8 having a spigot (not shown) on which the package rests with its axis vertical, each dish 8 having a spindle 10 mounted for rotation in bearings 11 secured to the horizontal member 4 of the creel.
  • Yarn or plastic tape indicated at 13 is drawn sideways from each package through 1 guide eyes 12 on the uprights and the tension in the yarn which isbeing wound for example by a beaming machine causes the packages and their supports, to rotate.
  • the brake mechanism to stop this overrun comprises an inflatable member in the form of a tube 14 which extends along each of the horizontal members 4 beneath all the dished package supports 8 and is located by clamps 16. Either a single tube may extend in a tortuous path so as to pass beneath all of the package supports or alternatively as illustrated in FIG. 6 a number of separate tubes one for each row, are employed each connected at 18 to a common manifold 20.
  • a separate brake strip 21 of wear resistant material is positioned between the tube 14 and the underside of the dishes 8.
  • the manifold, the tube, or each tube is connected to a source of compressed air or other fluid and means are provided to cause the tube to be inflated to the position shown in FIG. 3 when winding is interrupted.
  • a source of compressed air or other fluid and means are provided to cause the tube to be inflated to the position shown in FIG. 3 when winding is interrupted.
  • the tube is deflated and is in the position shown in FIGS. 1 and 2 so that it does not contact the'package or its support which can freely revolve.
  • inflation of the tube caused by operation for example of a standard stop motion generally illustrated at 22 (FIG. 7) which forms part of the beamer and which is connected to a valve controlling the supply of compressed air, the brake strip 21 is caused to engage the underside of the dishes 4 as shown in FIG. 3 immediately to stop rotation of the spindle.
  • a pneumatic valve 30 which is connected to the reservoir 28 by a line 32, is maintained in the position indicated at A by energization of a solenoid 34 so that air can pass from the supply through the valve 30 to a charge cylinder 36.
  • the solenoid 34 is energized by operation of the main drive start button for a short period to enable the beam to absorb any slack in the ends being wound especially so as to give end break detectors diagrammatically illustrated at 42 in FIG. time to close if no end is in fact still broken. Should, however, any of the ends not be properly joined then one of the contacts '42 remains open so that the holding coil 44will not be energized and hence the main contact 46 will reopen when the start button 38 is released.
  • the effect of the holding coil 44 acts to keep the main contactor 46 closed and when the start button is released the machine is kept energized as and until one of the end break detectors acts to open one of the contacts 42.
  • one form of suitable end break detectors or stop motion comprises a pivoted lever 48 having an eye 50 through which the yarn end runs between two fixed eyes 52.
  • the yarn end When the yarn end is not broken and is under tension it maintains the pivotal lever 48 in the position shown in FIG. 10 with a contact 54 in engagement of a second contact 56 providing a circuit through the contact generally indicated at 42 in FIG. 9.
  • the pivoted lever 48 pivots in a clockwise direction to the position shown in FIG. 10a in which the contacts 54 and 56 are apart and the contact generally indicated at 42 in FIG. 9 is open.
  • the holding coil 44 is deenergized and the main contactor 46 opens so as to stop the main drive to the machine.
  • the valve solenoid 34 is deenergized so that the pneumatic valve 30 shown in FIG. 8 changes over to the position indicated at B connecting by a line 58, the charge cylinder 36 to a pilot cylinder 60 of a pneumatic valve generally indicated at 62.
  • the pressure acts to change the valve 62 against its spring loading from the position shown at A to that shown at B.
  • air passes from the reservoir 28 through a pipeline 64 to the manifold and hence to the brake tubes 14 which are instantaneously inflated to stop the rotation of the various packages on the creel.
  • An air flow regulator 66 is located in the pipeline 58 and acts slowly to exhaust the charged air from the pilot cylinder 60 so that shortly after the brake tubes have been inflated the pneumatic valve resumes its natural position A under the influence of its spring and the air in the brake tubes is then able to exhaust through the valve 62 to an outlet generally indicated at 68 so as to remove the brake tubes from contact with the package supports so that they can then again freely rotate when the machine is restarted.
  • the pneumatic circuit also includes a pressure switch 70 which is located in the conductor extending between the start button 38 and coil portion 40 of theelectrical circuit shown in FIG. 9.
  • the purpose of this switch is to ensure that air is always supplied and if, for example, the supply fails or if the pressure falls below a certain value. the switch 70 will open and will act to stop the main drive while sufficient air remains?" shown in FIG. 5 which has the effect of lifting the spindle and hencethe package and its support relatively to the frame of" the creel and so that the dish 8 is clear of the brake pad 78.
  • the tube On operation of the stop motion of the beamer or an equivalent device the tube is caused to be deflated to the position shown in FIG. 4 whereupon the package and its dish drops relatively to the frame of the creel and the undersurface of the package support 8 contact the brake 78 to stop rotation.
  • the tube On resumption of winding the tube is again inflated so that the package is then lifted clear of the brake and normal winding can be recommenced.
  • the deflation of the tube can be achieved by the system essentially similar to that described above in connection with FIGS. 8, 9 and 10 but with the valve 62 arranged to connect the manifold 20 to the exhaust 68 when the pilot 60 is pressurized and to the supply when the pilot 60 is depressurized.
  • a method of braking packages mounted on a creel or the like comprising pressure varying the size of an inflatable member and employing the said. variation to cause the package with part of its support rotating therewith to engage a.
  • a creel or the like for supporting a number of rotatable packages of yarn or tape having package supports and having to their variation in size cause the package supports rotating a with the packages to engage the braking surfaces of the inflatable members to stop rotation of the packages.
  • a creel as claimed in claim 2 in which means are provided to cause the members to be pressure varied in size when winding is interrupted due to a-yarn or tape end break, also due to operation of a stop switch, the members being subsequently pressure varied in size to allow winding to commence.
  • a creel as claimed in claim 2 in which a number of in flatable tubes are provided each extending along a part of the creel and connected to a common feed pipe manifold.
  • a creel as claimed in'claim 2 in which the inflatable member is a single tube positioned in a tortuous path so as to act on all the packages on a creel.
  • a creel as claimed in claim 2 in which the inflatable members are positioned so that on inflation same directly engage a rotating package support.
  • each inflatable member is so positioned and arranged as, on inflation, to cause a separate wear-resistant brake surface to engage a package support rotating therewith.
  • a creel as claimed in claim 9 in which the inflatable members are so arranged and positioned that when inflated 11.
  • a creel as claimed in claim 4 including a fluid reservoir connected to the inflatable members, and a pneumatic valve which is arranged to be changed over to permit the inflation of the members by a solenoid which is energized or deenergized by said stop motion and also by end break detectors when a break in any yarn end occurs.
  • a creel as claimed in claim 11 having a pressure switch which acts to stop the machine if the pressure of fluid falls below a predetermined figure and simultaneously to cause the solenoid operated valve to change to the position in which the inflatable members are inflated.
  • a brake system for a creel as claimed in claim 2 comprising one or more inflatable tubes designed to extend along a number of packages on the creel, one brake member being provided for each package, and the inflatable tubes being each provided with a wear resistant surface; and a means to cause the tubes to be pressure varied in size on interruption of a circuit due to an end break.
