Definitions

  • Known manual attachment methods also include so-called depositing, also known as the American attachment method, in which the operator pulls the thread end in question past the delivery-side pressure roller of the drafting unit after removing an existing cleaning roller. A full constant removal of the cleaning roller by the operator is necessary, since otherwise the cleaning roller will prevent the operator from depositing the thread.
  • the operator has to work with two hands (one hand removes the cleaning roller while the second hand holds the thread).
  • the operator guides the thread manually with a lateral movement under the pressure roller in such a way that it is gripped and driven by the drafting system.
  • the operator holds the thread end in question, and with constant tracking of this held thread end, the thread then runs in transversely to the direction of travel, so that the path of the fiber stream is swept over and integrated.
  • Such a manual preparation takes a little more time, but is always successful, since the first meeting of the yarn and the fiber stream already takes place at the point where the spinning process finally takes place.
  • FIG. 13 and 14 schematically show a further variant of the operating robot 82 according to the invention, in which an additional auxiliary roller 154 is in turn used for the attachment.
  • the operating robot 82 or thread applicator 136 is constructed in the same way as described above.
  • a carrier 166 which is horizontally displaceably guided on the carriage 120 by means of a bearing block 164 is provided.
  • the auxiliary roller 154 is free to rotate stored in cash.
  • the auxiliary roller 154 is wider than the delivery roller 42 and can be pressed against the delivery roller 42 by means of a lifting motor 168.
  • the mouth 112 of the suction pipe 110 is arranged above the auxiliary roller 154. In the starting position A (cf. FIG. 14), the foreign thread 102 passes over the area of the auxiliary roller 154 which projects laterally beyond the delivery roller 42.
  • the auxiliary roller 154 is pressed against the delivery roller 42 and rotates with it.
  • the attachment process is analogous to that described above: shortly after the start of the pivoting movement of the suction pipe 110 from the position A to the position B, the brake 90 is released (cf. FIG. 2). After reaching position B, the suction tube 110 is pivoted back into position C approximately in the plane of symmetry of the spinning unit. As before, more than the full traverse stroke 70 of the roving 74 is swept over during the pivoting movement between the positions A and B (cf. FIG. 1), so that the foreign thread 102 securely grasps the stretched roving 74. Here, however, the spinning triangle is formed at the exit of the nip between delivery roller 42 and auxiliary roller 154.
  • the sliver separating device shown in FIG. 15 comprises a carrier section 210, a guide part 212 and a rocker arm 214.
  • the lever 214 is rotatably mounted on a pivot axis, which in this example is formed by a pin 216 (FIG. 16) embedded in the carrier section 210 .
  • the lever 214 has a working head 218 at one end, which is to be explained in more detail below together with the guide part 212.
  • the design of the other end 220 of the rocker arm 214 is less important for this invention and will only be described briefly at the end of this description in connection with the operation from an operating robot.
  • the sliver guide part 212 consists of the actual sliver guide 222 and a clamping element 224.
  • the sliver guide 222 has an essentially U-shaped slot 226 (FIG. 17). At the closed end of the slot 226, the sliver guide 222 has a rounded running surface 228 (FIG. 15) which merges into a clamping surface 230 of the clamping element 224 facing the pivot axis.
  • the surface 232 (FIG. 17) of the sliver guide 222 directed against the sliver running direction has a substantially pear-shaped bevel 234, which contributes to the condensation of the sliver as it enters the guide slot 226.
  • the part 240 adjoining the clamping element 238 only adds weight to the clamping head.
  • the rocker arm 214 is provided with a disk 256 (FIG. 18) which is pushed into a bowl-shaped part 258 (FIG. 16) of the carrier part 210 when the sliver separating device is assembled.
  • the disk 256 has on its side facing away from the lever 214 a projection 260 (dashed line, FIG. 18) with two stops 262 and 264.
  • a bolt 266 (FIG. 15) extending inside from the shell-shaped part 258 serves as a counter-stop, which together with the stops 262, 264 defined two limit positions of the lever 214 relative to the carrier section 210.
  • 19 has a rocker arm 214 and a guide 212 which have already been described in connection with the other figures and are therefore not explained again here.
  • the carrier section 210A is similar to that of FIG. 15, but is provided with a shoulder 268 which bears against the outer surface of a tube 270 installed in the spinning machine, so that the carrier section 210A can be connected to the tube 270 by a screw 272.
  • the tube 270 extends from the shoulder 268 beyond the guide 212 and (seen from a point upstream of the sliver separating device in the sliver conveying direction) closes off the open end of the U-shaped guide slot 226 (FIG. 17).
  • the surface 274 of the tube 270 facing the running surface 228 (FIG. 15) therefore forms a boundary surface which prevents the fuse from moving away from the running surface in the direction of the open end from the slots 226.
  • the surface 274 also serves as a threading aid in that, during the threading in, a fuse which has been unwound from a bobbin (not shown) can first be placed on the surface 274 and then threaded into the slot 226.
  • the tube 270 is preferably a continuous tube which extends over a plurality of spinning stations of the spinning machine and serves as a common carrier for a corresponding plurality of separating devices (one separating device per spinning station).
  • separating devices one separating device per spinning station.
  • the own separating device with its own carrier can be provided for each spinning station.
  • connection of the sliver separating device to a suitable carrier can also be solved differently than has been shown in FIG. 19.
  • a carrier section 210 (FIG. 15) could easily be connected to a carrier in the vicinity of the bowl-shaped part 258 (FIG. 16). It may then still be advantageous to provide a guide surface corresponding to surface 274 (FIG. 19) upstream of tread 228. It is also not necessary to connect the rocker arm 214 and the guide part 212 into one unit by means of a support part. However, this connection has the advantage that the unit can be assembled as a whole in the machine or can be removed from the machine.
  • the free end part 220 (FIG. 15) of the rocker arm 214 serves as an operating part. It has a side extension 280 and a surface 282 that is beveled with respect to the longitudinal axis of the lever.
  • the attachment 280 serves as a stop, which can be pushed by an operating element of the robot, not shown, in the counterclockwise direction (according to FIG. 15) in order to move the working head 218 from its ready position into its operating position.
  • the fuse is clamped between the rod 238 (FIG. 18) and the clamping surface 230.
  • the clamping action occurs before the clamping head 218 has reached its limit position (dashed line, FIG. 15).
  • the clamping effect is in no way dependent on the operating robot, but initially only on the weight of the clamping head.
  • the sliver is pulled apart by the conveying action between the sliver separating device and the conveying device.
  • the separation point depends on the adhesion of the fibers in the fuse, but will normally be close to the nip, so that the fuse is thinned in the nip.
  • the fuse remains securely threaded with the guide 222 and is ready to be re-threaded into the sliver conveyor (into the drafting system) as soon as the clamping head 218 is inserted by an operator by tilting the lever 214 clockwise (FIG. 1).
  • the surface 282 is provided with a reflective film (not particularly indicated) and is approximately vertical in the ready position of the lever 214.
  • This film serves as a "scanning surface", according to which an optical sensor provided on the operating robot can determine whether the sliver separating device is in the operating position or in the standby position in a specific spinning position. If it is determined by this sensor that the sliver separating device is in the operating position, the operating robot can drive past this spinning station without performing an operating operation, since this spinning station requires manual operation and can be classified as "defective" for the operating robot.
  • the surface 262 can also be provided with a film (229 colored red), e.g. to visually represent the condition of the disconnect device for the operating personnel.
  • the parts shown are suitable for production (e.g. from plastic) by means of a casting process (i.e. without further processing), in which case the carrier section 210 and the guide part 212 can be cast from one piece and the lever 214 together with its disk 256 from a second piece.
  • the clamping surface on the rocker arm is rounded up. Furthermore, the rocker arm and the guide have been formed into a unit by a carrier section, the guide being provided with a threading opening.
