Definitions

  • the invention relates to a device for pneumatically detecting and pulling off the end of a cop by means of a swirling and / or helically sweeping air flow over the surface of the cop, which is designed such that the loosened end of the thread is gripped above the head sleeve and / or automatically into a standby point , is passed to a thread connecting device, winding device or the like.
  • Such a device is intended to prepare a cop for unwinding.
  • a cop originating from a ring spinning machine usually has a rear winding that leads downwards in a helical line with a large pitch from the tip cone over the cylindrical part of the cop.
  • Sometimes the back winding also ends in a winding around the base of the sleeve.
  • the cops are wound into cross-wound bobbins in winding machines or automatic winding machines. To do this, it is necessary to grasp the end of the thread and pull it off overhead to remove at least the rear winding. If this happens in a preparation station, the end of the thread is returned to the cop, if possible at a defined point, so that it later can easily be found for unwinding the cop. If, on the other hand, the end of the thread is grasped in a winding station, not only the end of the thread but then the entire thread is pulled off the bobbin.
  • the invention has for its object to provide a reliably working device with which the thread end can be pneumatically detected and removed overhead of the cop, but the cop change should be carried out as quickly and reliably as possible.
  • Fig. 1 shows a device according to the invention schematically in side view.
  • Fig. 6 shows a longitudinal section through the upper part of a sleeve of the device according to the invention.
  • Fig. 7 shows in section further details of the cuff.
  • Fig. 8 shows the divided sleeve shown in Fig. 7 in cross section.
  • FIG. 9 shows a top view of details of a sleeve of a device according to the invention.
  • Fig. 10 shows in section the foot end of a cuff and a single head carrier lifter.
  • Fig. 11 shows in section the foot end of another cuff.
  • Fig. 12 shows a top view of a twine loosening device in the switched-off state.
  • FIG. 13 shows a top view of the twine loop release device shown in FIG. 12 in the switched-on state.
  • the device 31 arranged underneath a winding unit 2 of an automatic winder has an automatic head transport device 32 for heads 35, 36, 37 provided with back windings 33, 34.
  • the heads stand on individual head carriers 38, 39, 40.
  • Fig. 10 shows further details of the single head carrier 38. It consists of a disc-like foot part 42, a single-stage or multi-stage structure 43, 44 and an arbor 45 for the sleeve of a cop. At least the foot part 42 has the shape of a circular disk or a circular ring. The arbor 45 is located concentrically above the foot part 42. In the present exemplary embodiment, the foot part 42 should be solid and have air passage openings 46 to 49.
  • the device 31 has a longitudinally divided sleeve 50 which surrounds the cop 35 to be unwound and which is provided with tangential and at the same time obliquely upwardly directed blowing nozzles 51, 52, 53.
  • the flexible nozzles 51, 52, 53 are connected to a controllable valve 57 by flexible lines 54, 55, 56, which valve is connected to a compressed air source 58 via a plug connection.
  • the thread take-up element consists of a suction mouth 25 of a suction tube 24 which can be moved along the circular arc 26.
  • FIG. 12 shows, among other things, a view from above of the cuff 50. It is longitudinally divided and consists of the cuff parts 50a and 50b. At its foot end, the cuff 50 is provided with widenings enclosing the individual head carrier 38 of the head 35. The widening of the cuff part 50a is denoted by 50a 'and the widening of the cuff part 50b by 50b'.
  • the cuff 50 is divided into two parts of equal size by dividing joints 59, 60.
  • the dividing joints 59, 60 are such that when the cuff parts 50a, 50b are placed against one another there is a pipe from a fluidic point of view, through the lateral joints of which no transverse flows of harmful size can pass.
  • the division joints 59, 60 lie at an angle of 45 degrees to the direction of movement 61 of a support surface of the head transport device 32, which will be explained in more detail later.
  • each of the two cuff parts of the cuff 50 is provided with a cuff holder 62 and 63, respectively.
  • the cuff holder 62 is provided with a control device 64, the cuff holder 63 with a control device 65.
  • the control devices 64, 65 are connected to the machine frame 5 of the device 31 by traverses 66, 67.
  • control devices 64, 65 are designed as pneumatic control pistons, the piston rods of which form the sleeve holders 62, 63.
  • Other control devices which will be discussed later, are also possible.
  • the two control devices 64 and 65 already belong to the head transport device 32, which will be discussed in more detail below. It has a support surface 70, which constantly moves from a cop delivery point 68 under the sleeve 50 to a delivery point 69, for head carriers 38, 39, 40 which are guided along this support surface and can be lined up, for example, through side walls of the machine frame 5.
  • the head transport device 32 has the two in one Cop change signal of the automatic winder 1 responsive control devices 64, 65 for the two cuff holders 62, 63.
  • the support surface 70 here has the shape of an endless conveyor belt which is guided over rollers 71, 72 and runs continuously. For this purpose, the roller 71 has a drive device, not shown here.
  • FIG. 1 shows a central control device 73. From this central control device 73, operative connections 74 lead to the control devices 64 and 65. These operative connections consist, for example, of flexible, pneumatic lines which are easily detachably connected to the central control device 73 by plug connections.
  • the two control devices 64 and 65 react to a thread signal of the thread take-up element 25.
  • the front compressed air connection of the pneumatic servomotor 64 is pressurized with compressed air, whereby the sleeve holder 62 is withdrawn and with it the sleeve part 50a is removed from the sleeve part 50b.
  • the rear compressed air connection of the pneumatic servomotor 64 is pressurized with compressed air, as a result of which the sleeve 50 closes again.
  • the front compressed air connection of the other pneumatic servomotor 65 is pressurized with compressed air, so that the cuff holder 63 with the cuff part 50b is withdrawn, against the widening 50b 'of which the further individual head carriers 39 and 40 with attached heads 36 and 37 are present from the outside. Due to the retraction movement of the widening 50b ', these two single head carriers 39 and 40 are first pushed back against the direction of movement 61 of the support surface 70, but then the path into the interior of the sleeve 50 is clear, so that in a short time the single head carrier 39 takes the place that previously had the single head carrier 38.
  • the cuff 50 then closes by pressurizing the rear compressed air connection of the pneumatic servomotor 65 with compressed air.
  • the edge of the widening 50b ' pushes between the two single head carriers 39 and 40, whereby the single head carrier 40 is pushed back, which then bears against the edge of the widening 50b'.
  • a program switching mechanism contained in the central control device 73 which can work, for example, electronically or also mechanically with cam disks, now switches on the valve 57, as a result of which a helical blown air flow is created in the sleeve 50, which is directed against the intake opening 25.
  • the helically upward air flow detects the rear turn 33 of the cop 36 now standing in the sleeve 50 and carries it upward out of the sleeve 50 into the suction area of the suction mouth 25.
  • valve 57 closes again. If the cop is now not to be handled on the spot, a thread scissors present in the suction tube 24 comes into operation. The thread end newly formed by the thread cut falls back onto the cop and can easily be picked up again later.
  • the cop delivery point 68 which can be designed, for example, as a conveyor belt.
  • the delivery point 69 can also be designed as a conveyor belt, as shown in FIG. 1.
  • blowing nozzles 139 to 141 can be arranged, for example, uniformly over the circumference at approximately one height.
  • the lower series of the blowing nozzles represented by the blowing nozzle 139, lies at the level of the piecing cone 144 or 145 of the cop 146 or 147.
  • blowing nozzle 143 can already be at the height of the upper cone section 148 in the case of smaller cops.
  • a further series of blowing nozzles can be arranged above this, which would then also lie at the level of the cone section in the case of larger cops. Since the tangential direction of the blowing nozzles has to be based on the winding direction of the cop, alternatively or additionally oppositely directed blowing nozzles 140 'according to FIG. 8 can be present. Plug connections and interchangeable plugs could be used to easily and flexibly reconnect the flexible cables if copes with the opposite winding direction were to be processed.
  • a loop of thread loosening device 149 is arranged above the sleeve 50. It has the task, especially in the case of weak yarn tension, to untie loops and curls if the thread is to be unwound on the spot, or even when the thread enters the suction mouth 25.

  • the twine loop release device 149 has two arms 153, 154 which can be moved against and away from one another and are provided with stops 151 and 152 at the ends.
  • the arms 153, 154 are designed as scissor-like overlapping webs.
  • concave edge parts 153 ', 154' of the webs and by a respective arranged in the middle of the concave edge notch 155 and 156 a yarn guide device for the yarn 12 is formed in the switched-on state according to FIG. 13 in the longitudinal axis 183 of the sleeve 50.
  • the webs 153, 154 overlap like scissors, but at a distance from one another so that the yarn 12 cannot be pinched between the webs 153 and 154.
  • the stop 152 of the web 154 lies against the stop 151 of the web 153, which among other things determines the precise position of the yarn guiding device 155, 156, among other things.
  • the webs 153, 154 form stop surfaces for loops, curls or the like, which may migrate upward from below with the yarn 12.
  • the notches 155, 156 form, in the switched-on state of the yarn loop dissolving device 149, partial looping points for the continuous yarn 12, as a result of which an increase in yarn tension occurs in the downstream section of the yarn.
  • the control device 150 consists of a pneumatic servomotor, the piston rod 158 of which is articulated to a lever 160 via an intermediate piece 159.
  • the lever 160 is connected to a shaft 161 mounted on the machine frame.
  • the arm 153 and also a gear 163 are also connected to the same shaft.

  • the shaft 162 is also mounted in the machine frame. Your pivot axis is designated 157.
  • This gear-like coupling of the two arms 153 and 154 ensures their opposite, synchronous movement.
  • FIG. 9 shows a practical training for this in connection with FIG. 6.
  • FIG. 9 shows that each cuff part 50a, 50b is connected to a cuff holder 181 or 182 and that each cuff holder 181, 182 is pivotable about an axis 184 or 185 parallel to the longitudinal axis 183 of the cuff 50.
  • the cuff holders 181, 182 are connected to hollow shafts 190 and 191 pivotably mounted vertically in bearings 186 (FIG. 6) and 188, respectively.
  • the bearings 186, 188 are connected to the machine frame 5 (Fig. 1, Fig. 6).

  • the levers 193 and 194 are firmly connected to the associated hollow shafts 190 and 191, respectively.
  • FIG. 9 indicates that by pulling the rod 199 back, the sleeve part 50b can be pivoted along the pivot paths 201, 202 shown in broken lines to the position 205 shown with broken lines. In this position of the cuff part 50b, the path would be free for a single head carrier to reach the stopped cuff part 50a in the direction of movement 61 of the support surface or the conveyor belt 70.
  • the other cuff part 50a could also first be pivoted counterclockwise by a small pivot angle about the axis 184 and then pivoted back into its starting position. After retracting a single head carrier with the cop attached, the cuff part 50b could be put out of position 205 by pushing the rod 199 back against the other cuff part 50a, after which the cuff 50 would then be ready for operation again.
  • the other cuff part 50a can be pivoted counter-clockwise about the axis 184 and brought along the pivot paths 203, 204 shown in broken lines to the position 206 shown in broken lines. This would clear the way for a single head carrier previously held in the cuff 50 to move further in the direction of movement 61 of the support surface or the conveyor belt 70.
  • the cuff part 50b could also first be pivoted through a small angle before it is pivoted away completely after the other cuff part 50a has been pivoted back in order to accommodate a further individual head carrier.

  • the entire arrangement tilts such that, for example, the cop 35 shown in FIG. 6 leans against the wall of the sleeve 50.
  • the time at which the single head carrier lifter 222 is switched off and the time at which the control device 150 of the twine loop release device 149 is switched on is set to the time at which the controllable valve 57 of the blowing nozzles 51, 52, 53 of the sleeve 50 is switched off. This ensures that the single head carrier remains raised only as long as the blown air is still flowing. After it has been determined or can be expected that the thread has already reached the lower thread take-up element 25, the twine loop release device 149 goes into operation.
  • the device 31 can be designed essentially as a transportable unit or a transportable yarn delivery unit 3.

If the scissors 324 are used, the arrangement of a suction tube scissors is unnecessary. If, however, the cop is to be unwound on the spot, the scissors 324 only become one on the occasion Kops Panel operated to cut any existing drag thread.

  • the embodiment according to FIG. 11 differs from the embodiment according to FIG. 10 essentially in that the diameter of the sleeve 500 remains unchanged up to its lower end, so that an advancing single-headed member does not move with its foot part against the foot part of a sleeve, but against the foot part 42 of the single head support 38 comes to rest. This reduces the space requirement.
  • Fig. 9 indicates that to drive the shaft 179 a lever 264 connected to the shaft 179 may be present, which is articulated to an actuator 215 'and can take over switching tasks. It can be connected to the central control device 73 (FIG. 1) through the operative connection 218.
