Definitions

  • the invention relates to a method for changing spinning cans in a spinning preparation machine, to which a plurality of slivers removed from spinning cans are fed for processing, in which an empty sliver can is replaced by a full sliver can and a sliver contained in the full sliver can is accommodated, and a device for carrying it out of the procedure.
  • a method of the type mentioned at the outset is used, for example, in lines in which a number of fiber slivers are drawn.
  • the slivers are contained in spinning cans and are fed to the drafting system. Empty spinning cans are replaced by full operators with full spinning cans. Furthermore, the operator removes the sliver contained in the new, full sliver can and feeds it to the drafting system. This manual change of the spinning cans requires considerable effort and great skill on the part of the operator. An exact integration of the beginning of the new sliver into the entirety of the incoming slivers without a recognizable attachment point is not guaranteed.
  • the object of the invention is to provide a method and a device for changing spinning cans in a spinning preparation machine, which in each case ensures an exact incorporation of the new beginning of the band into the entirety of the incoming slivers and thus increases the quality of the drawn sliver.
  • the full spinning can is provided in a reserve position, a movable carriage is delivered to the full spinning can, the sliver is gripped by a gripper held on the carriage and inserted into the machine, and in that then the full spinning can is moved to a working position.
  • Changing the sliver cans and picking up and inserting the sliver contained in the new, full sliver can is carried out automatically. Inaccuracies or errors that can arise from manual intervention are reliably avoided.
  • the sequence of the changing process can be precisely predetermined and set so that an exact integration of the beginning of the new sliver into the entirety of the incoming slivers is possible. Attachments or the like in the drawn sliver can be improved in this way. Due to the automatic process, the changing process is reproducible, so that overall a stretched fiber sliver is obtained with a consistently high quality.
  • the full spinning can is bypassed by the gripper to capture the sliver. Finding the beginning of the new sliver is also carried out automatically. Manual intervention by an operator is not required.
  • the sliver is sucked in by a suction air flow guided by the gripper.
  • This measure makes it easy to find and detect the new sliver. The only requirement for this is that the beginning of the new sliver hangs, for example, on the outer wall of the full sliver can. A search revolution of the gripper is then sufficient to locate and suck the sliver in any case.
  • the sliver is placed by the gripper on a feed table.
  • the feed table is used to feed the slivers removed from the spinning cans to the spinning preparation machine.
  • the slivers are arranged in parallel on the feed table.
  • the new sliver is placed on the feed table with the aid of the gripper, so that it is carried along by the slivers present there and is fed to the spinning preparation machine.
  • the sliver is shortened to a predetermined length before being placed on the feed table. To do this, it is possible to clamp and cut the sliver on the gripper.
  • the empty spinning can is pushed out of the working position by the full spinning can.
  • the empty spinning can is therefore only removed at the last possible time, so that unwanted looping or knotting of the sliver removed from the empty spinning can is reliably avoided.
  • a device for changing spinning cans in a spinning preparation machine, to which a plurality of slivers removed from spinning cans are fed for processing, is characterized in that a movable carriage can be moved to a reserve position, a gripper is held on the carriage with which a sliver can be gripped and into which Machine can be inserted, which is contained in a full spinning can provided in the reserve position, and means are provided for moving the full spinning can into a working position.
  • the new, full spinning can is provided in the reserve position by an operator or automatically with the help of appropriate devices.
  • the car is on Rails can be moved and will be delivered to the reserve position.
  • the gripper attached to the carriage grips the sliver contained in the new, full spinning can and feeds it to the spinning preparation machine for further processing.
  • the full spinning can is then moved to the working position and the changing process is complete.
  • the carriage and / or the gripper is provided with a rotating device with the aid of which the gripper can bypass the full spinning can. The beginning of the sliver hanging from the side of the full sliver can can be found and detected in this way.
  • a suction device is provided, to which a suction opening contained in the gripper is connected. In this way, the detection of the sliver is guaranteed in any case.
  • the slivers to be processed by the spinning preparation machine are fed to the latter with the aid of a feed table.
  • the spinning cans from which the slivers are removed are arranged in a row in their working position under the feed table. After the sliver of the new, full spinning can has been gripped by the gripper, it is placed on the feed table and the full spinning can is pushed from the reserve position into the working position. The sliver laid on is taken along by the slivers on the feed table and fed to the spinning preparation machine for processing.
  • the changing device shown in FIGS. 1 to 3 is assigned to a route, not shown. It is used to replace spinning cans from which slivers are removed, fed to the draw frame and stretched by it.
  • a stretch is provided by way of example in which four fiber slivers are stretched simultaneously.
  • three full spinning cans (12, 13, 14) are arranged in a row next to one another in reserve positions. Parallel to the row formed by the full spinning cans (12, 13, 14), a further full spinning can (10) and three empty spinning cans (16, 17, 18) are arranged next to one another in a row in working positions.
  • the reserve positions and the working positions are assigned to one another, so that the full spinning cans (12, 13, 14) can be moved from the respective reserve position into the associated working position with the aid of push cylinders (20).
  • the full spinning cans (12, 13, 14) are displaced approximately transversely to the rows formed by the spinning cans, as is shown by way of example with the inserted full spinning can (10) in FIG. 1.
  • the guide and positioning of the full spinning cans (12, 13, 14) when moving from the reserve to the working position can be attached to the push cylinders (20) Push jaws (21) take place.
  • the spinning cans (12, 13, 14) can run on inclined roller conveyors which are provided with lateral guides. Retractable pawls or stops can be provided in the roller conveyors for positioning the spinning cans (12, 13, 14).
  • a carriage (30) can be moved over the spinning cans (12, 13, 14) with the aid of a rail system which is composed of longitudinal rails (32) and transverse rails (33) arranged approximately at right angles to one another, which are attached to the ceiling or other supporting elements.
  • the carriage (30) can be positioned coaxially via each of the reserve positions assigned to the individual full spinning cans (12, 13, 14), as well as other similar spinning preparation machines.
  • the carriage (30) is divided into a stationary part (66) and a part (67) which can be rotated about a vertical axis.
  • Two vertically arranged lifting cylinders (35) are attached to the rotatable part (67) at a distance from the axis of rotation.
  • the arm (37) is shown in a vertically downward position, while in Fig. 3 the arm (37) is arranged approximately horizontally.
  • the pivot axis (38) of the arm (37) is arranged with respect to the axis of rotation of the rotating device in such a way that the arm (37) in its position shown in FIG. 2 is a short distance from the outer circumference of the full spinning can placed under the carriage (30) (12).
  • the arm (37) bypasses the full spinning can (12).
  • the length of the lifting cylinder (35) is selected such that the arm (37) is pivoted into the horizontal position in the raised state and then can be lowered into the position shown in FIG. 3 via a feed table (50).
  • a suction device is contained in the carriage (30), to which a suction opening (42), which is arranged at the free end of the arm (37) and is directed towards the axis of rotation of the rotating device, is connected via a hose (43). Furthermore, the arm (37) is provided with a clamping and separating device in a manner not shown.
  • the feed table (50) already mentioned is arranged above the spinning cans (10, 16, 17, 18) in their working positions, or the like in a manner not shown on carriers. is attached.
  • the feed table (50) is arranged approximately horizontally and forms a rail for feeding the fiber slivers (55) removed from the spinning cans (10, 16, 17, 18) placed underneath.
  • Each of the spinning cans (10, 16, 17, 18) is assigned a feed roller (52) which is arranged approximately horizontally and is mounted on the feed table (50) and over which the sliver (59) removed from the associated spinning can is guided. This is shown by way of example in FIG. 1 on the basis of the full spinning can (10) that is engaged in its working position.
  • the direction of feed of the fiber slivers (55) placed on the feed table (50) is identified by an arrow (64) in FIG. 1.
  • the empty spinning can as shown in FIG. 1 is replaced by the full spinning can (10) with respect to the feed most distant from the drafting system. Then the empty spinning cans (16, 17, 18) are pushed out of the working positions one after the other and the full spinning cans (12, 13, 14) are pushed into the working positions.
  • the carriage (30) Before transferring the full sliver can (12, 13, 14), the carriage (30) is positioned coaxially over the full sliver can (12), the arm (37) being located between the full sliver can (12) and the feed table (50) .
  • the vertically aligned, lowered arm (37) once surrounds the full sliver can (12) and, with the help of the suction air flow generated by the suction device, detects the beginning of the sliver (57) of the sliver contained in the full sliver can (12).
  • the beginning of the band (57) is drawn into the suction opening (42), which is detected with the aid of a light barrier or another sensor.
  • the beginning of the tape (57) is clamped to the arm (37) by the clamping device and shortened to a predetermined length with the aid of the separating device.
  • the arm (37) is raised with the aid of the lifting cylinders (35) and the pivoting cylinder (40) one after the other according to the arrows (60, 61, 62), pivoted outwards and lowered again.
  • the arm (37) with the detected tape start (57) is above these feed movements (50). This state is also shown in FIG. 1.
  • the carriage (30) is then moved in the longitudinal direction to the next full spinning can (13), the beginning of the belt (57) passing over the assigned feed roller (52) pulled and at least partially placed on the feed table (50).
  • the clamping device is opened so that the beginning of the belt (57) is released by the arm (37) and falls onto the feed table (50).
  • the full spinning can (12) is moved from the reserve position into the working position.
  • the empty spinning can (16) is pushed out of the working position by the full spinning can (12).
  • the arm (37) is now brought back into its vertical and lowered position shown in FIG. 2 and the process described is repeated again with the full spinning cans (13 and 14).
  • Switching off the line before changing the sliver can and the described laying of the respective slivers on the feed table (50) during the sliver can change is coordinated with one another in such a way that the sliver ends of the "old" slivers and the beginning of the "new" slivers are at least partially accurate definable length overlap.
  • An operator can provide the full spinning cans (12, 13, 14) in the respective reserve positions.
  • the pushed out empty spinning cans (16, 17, 18) can also be removed by an operator.
  • the full and empty spinning cans are automatically prepared and removed. In this way, a fully automatic changing device can be created, or the like by a control device, in particular a microcomputer. is controlled and no longer requires manual operation.
  • the respective band starts (57) of the "new" fiber bands (55) removed from the full spinning cans (10, 12, 13, 14) are not placed on the feed table (50), but by the arm (37) Movement of the carriage (30) in the direction of the drafting system pulled over a band rake, not shown, and deposited.
  • the band starts (57) of the "new" fiber bands (55) have an exact starting position when the drafting system is switched on. This position can be taken into account in the drafting system by changing the drawing, so that the quality of the drawn fiber sliver can be improved.
  • the drafting system for changing the spinning cans is stopped.
  • the deviations resulting from such a change due to the briefly missing sliver can be compensated for by the subsequent drafting system or a subsequent regulating section or can be eliminated as waste.
  • the runout of the slivers from the cans (10, 16, 17, 18) in the operating position is monitored. This can be done, for example, by attaching a marking to the spring plate of the cans (10, 16, 17, 18) which can be recognized by a sensor when this spring plate moves out of the can or when the sliver is removed from the can in question has been and the marking is no longer covered. The operating speed of the machine is then reduced on the basis of the signal which is emitted by the first can (10, 16, 17, 18) which is running out.
  • the can is then changed at a reduced speed, so that it can be ensured that the "new" sliver "can be put on the old sliver" in good time so that the can can be changed without the machine being stopped.
  • the machine is raised to the operating position.
