Definitions

  • the invention relates to a method for feeding conical tubes to the winding units of a textile machine, wherein tubes inserted into one another in the form of columns are kept ready at a storage location and separated for removal, and each individual tube is brought into a conveying position and transferred to a storage and transport device in which the Sleeves are stored and transported to the winding stations of the textile machine, as well as a device for performing the method.
  • FR 2 543 931 A1 it is known to separate sleeves from a sleeve column and to transfer them to a conveying device which feeds the sleeves to a magazine.
  • the sleeves are first conveyed in an upright position and then pivoted into a vertical position by the conveying means. Starting from this position, the sleeves are transferred to a magazine via a slide.
  • a defined position of the sleeve relative to the conveying means is first produced after the separation. This position does not correspond to the position of the sleeve, which is required for changing the bobbin.
  • the conveyor changes its direction of conveyance, whereby the sleeves lose their defined position in the conveyor.
  • the sleeves After the sleeves have been transferred to the mobile magazine, the sleeves must be repositioned so that they can be transferred from the magazine to the winding unit.
  • the conveying position which has already been produced and which contains a defined position of the empty sleeve is therefore initially abandoned here by the further transport steps and must then be restored again. This makes the device complex and prone to failure.
  • the object of the present invention is to provide a method and a device which make it possible to feed the sleeve detached from a sleeve column in a simple manner to the winding stations in the position required for changing the bobbin.
  • the sleeve is stripped from a vertically arranged sleeve column in the direction of its conically tapering end and is then brought out of its vertical position into a horizontal position in which it is transferred to the magazine.
  • the transfer of the sleeve to the magazine is advantageously carried out successively until sleeves have been transferred for all storage locations of the magazine, whereupon the magazine returns to its starting position.
  • the device for performing the method with a sleeve magazine in which at least one sleeve column formed from nested conical sleeves is arranged, with a device for separating the sleeves and with means for transferring the individual sleeves from their column-like position into a conveying position, with a device for Saving and for transporting the sleeves to the bobbin stations of the textile machine, and with means for transferring the sleeve into the storage and transport device, is characterized in that the storage and transport device consists of a conveyor belt which extends over all bobbin stations as a means for transferring the sleeves into their conveyor system, an arcuate sleeve slideway is used, which is arranged downstream of the sleeve magazine, and that the means for transferring the sleeve into the storage and transport device maintains a conveying position of the sleeves have sponsors.
  • the sleeve is preferably brought into a horizontal conveying position by an arc-shaped sleeve slideway downstream of the sleeve magazine, which ends at a horizontally arranged sleeve storage table.
  • transfer means for transferring a sleeve to an ascending conveyor are assigned to the sleeve storage table, which is followed by a gripper which transfers the sleeve to the conveyor belt.
  • the position of the sleeve fixing stops are assigned to the sleeve storage table.
  • The in Provide the direction of sliding of the sleeve at the rear stop with a means that dampens the sleeve impact.
  • a possible spring back of the sleeve on the sleeve slide is prevented in a simple manner in that the front stop in the sliding direction of the sleeve is formed by the sleeve slide.
  • the transfer means assigned to the sleeve storage table are designed as pivotable brackets.
  • the brackets are preferably attached to a rotatably mounted bearing block.
  • a rotary movement of the bearing block about its axis, from which a pivoting movement of the bracket results is generated via a lever arm attached to the bearing block, to which a cam lever is articulated.
  • the pivoting movement of the brackets in the direction of the ascending conveyor is effected by a sleeve driver of the ascending conveyor acting on the cam lift.
  • the sleeve lying on the sleeve storage table is transferred to the same sleeve driver that actuates the cam lever. Because the brackets are adjustable transversely to the direction of travel of the ascending conveyor in the bearing block, their position can be changed and sleeves of different conicity and diameter can be adapted.
  • the textile machine 1 for example an open-end spinning machine, of which only one end frame is shown in FIG. 1, has the usual multitude of work stations, each with a winding device for winding yarn onto a tube.
  • the individual winding devices are supplied with empty tubes by means of a conveyor belt 2 provided with tube holders 20, which is arranged above the winding units.
  • the sleeves are inserted into the sleeve holders 20 in a sorted manner in the longitudinal direction of the machine.
  • the conveyor belt 2 is assigned a stationary sleeve loading device, which is located in a housing 3 at one end of the machine 1.
  • the sleeve loading device contains a sleeve magazine, designated overall by 4, which receives at least one sleeve rod or sleeve column 5.
  • the sleeve column 5 is formed from nested conical sleeves 50 and arranged upright in the sleeve magazine 4, the tapered ends of the sleeves pointing in the opening direction of the sleeve column 5, that is to say downwards in the exemplary embodiment.
  • a horizontally arranged turntable 42 which is fastened on an axis of rotation 41 and has a plurality of passage openings 43 arranged on a circular path, each serves for a sleeve column 5 (FIGS. 1 and 2).
  • the axis of rotation 41 is mounted standing on the stationary base plate 44.
  • One of the sleeve columns 5 stands on a support in the form of a base plate 45 which can be pivoted out of the vertical plane of the sleeve column 5 and which is fastened on a rotatably mounted and drivable axis 46.
  • the sleeve columns 5 which are in reserve are supported on a stationary base plate 44 and can be moved one after the other onto the pivotably arranged base plate 45 by rotating the turntable 42.
  • a further turntable 47 provided with through openings is fastened on the axis of rotation 41 between the turntable 42 and the base plates 44 and 45 at the level of the last sleeve of the sleeve columns 5.
  • the last sleeve of the sleeve column 5 to be opened receives precise guidance through the second rotary plate 47.
  • the sleeve column 5 standing on the pivotable base plate 45 is assigned a device arranged on the axis of rotation 46 for separating the sleeves inserted into one another, which has a movable sleeve clamp 48, which cooperates with a stationary sleeve clamp 481, for clamping the penultimate sleeve and a rotational axis 46 which can be moved in the vertical direction attached sleeve stripper 49 for stripping the last sleeve from the sleeve column 5 contains (Fig. 5).
  • the two clamping jaws 48 and 481 are arranged on a bearing plate 482, the clamping jaw 48 being pivotable about an axis 483 arranged on the bearing plate 482.
  • the pivoting movement takes place, for example, by means of a compressed air cylinder 484, the piston rod of which is connected to a pin arranged on the clamping jaw 48.
  • the sleeve scraper 49 is fastened on the axis of rotation 46, which is rotatably guided in the fixed clamping jaw 481 and a tab 462 connected to the piston rod of a compressed air cylinder 461 is.
  • a compressed air cylinder 491, the piston rod of which is connected to a pin on the sleeve scraper 49, causes the rotary movement of the axis 46 and thus the movement of the sleeve scraper 49 towards the sleeve column and the pivoting of the base plate 45 out of the area of the sleeve column 5.
  • a low clamping pressure is sufficient to hold the penultimate sleeve by means of the clamping jaws 48 and 481, since if the axial loading force acting on the sleeve and possibly exceeding the clamping force of the clamping jaws in the sleeve wiping direction, this penultimate sleeve with its conically enlarged diameter enters the clamping jaws 48, 481 moved in and so clamped itself. This prevents damage to the sleeves.
  • the last sleeve of the sleeve column is equally gently detached from the sleeve column by the sleeve scraper 49 which bumps onto the edge of the sleeve.
  • a conveyor device is arranged between the sleeve magazine 4 and the conveyor belt 2, by means of which a sleeve 50 detached from the sleeve column 5 can be brought into a conveying position and fed to the conveyor belt 2 in the conveying position.
  • the conveying device contains a sleeve slideway 51 which is arranged below the pivotable base plate 45 and which is bent in the direction of a sleeve storage table 52 which is mounted on the side and below the sleeve magazine 4 and ends at this.
  • the upward moving run of an ascending conveyor 6 runs past near the sleeve depositing table 52, the sleeve drivers 61 (FIG.
  • Transfer means for transferring a sleeve 50, which is placed on the sleeve storage table 52 and protrudes laterally beyond it, to one of the sleeve drivers 61 of the ascending conveyor 6 are assigned to the sleeve storage table 52.
  • Brackets 71 are provided as transfer means, which are arranged on both sides of the sleeve storage table 52, so that they can grip a sleeve 50 lying thereon in the vicinity of their two ends.
  • the brackets 71 are clamped in a bearing block 7 by means of a clamping strip 72 and can be adjusted in the direction of the ascending conveyor 6 and against this direction in the bearing block 7 after loosening screws 73 (FIG. 4).
  • the bearing block 7 is rotatably mounted in its holder.
  • the last sleeve is first removed from the sleeve column 5 standing on the pivotable base plate 45 above the sleeve slide 51.
  • the penultimate sleeve of the sleeve column 5 is held by means of the sleeve clamps 48 and 481
  • the base plate 45 is pivoted out of the area of the sleeve column 5 and the last sleeve is stripped from the sleeve column 5 by the sleeve stripper 49 acting on the upper sleeve edge.
  • This sleeve 50 falls with its tapered end ahead onto the arcuate sleeve slide 51 and slides down there, initially coming from its vertical position into an inclined position and upon arrival on the sleeve storage table 52 into a horizontal position.
  • the tapered end of the sleeve 50 abuts against a stop 53, which can be coated with a means that dampens the impact of the sleeve.
  • a possible spring back of the sleeve 50 on the slide is prevented in a simple manner by arranging the sleeve storage table 52 somewhat lower than the sleeve slide 51 so that, as can be seen in FIG. 2, the outlet edge of the sleeve slide 51 itself has a stop for the sleeve 50 forms.
  • a stop 54 is also arranged on the sleeve storage table 52, which has a contact surface for the sleeve 50 which is inclined in the direction of the ascending conveyor 6 and prevents the sleeve 50 from rolling off in this direction. Contrary to this direction, the sleeve 50 is held by a vertical wall 55 of the sleeve storage table 52 or by the bracket 71.
  • the sleeve 50 thus brought into a conveying position and centered on the sleeve storage table 52 is then transferred to a sleeve driver 61 of the rotating ascending conveyor 6. This happens as soon as one of the sleeve drivers 61 abuts against the cam lever 74 and presses it into the position 74 ', whereby the bearing block 7 is rotated about its axis via the lever arm 75 and the brackets 71 pivot in the direction of the ascending conveyor 6 into the position 71' .
  • the stirrups 71 take the sleeve 50 with them and transport them across the stop 54 in a horizontal position onto the sleeve driver 61, which has triggered the pivoting movement of the stirrups 71 and assumes the position 61 'when the sleeve is handed over.
  • the sleeve drivers 61 are continuously loaded with sleeves 50 and conveyed horizontally upwards by the ascending conveyor 6.
  • the sleeve arriving at the upper end of the ascending conveyor 6 is then gripped by a gripper 8 which can be moved between the ascending conveyor 6 and the conveyor belt 2 and which, in its conveying position, places it in a sleeve holder 20 of the conveyor belt 2.
  • the transfer of the sleeves 50 to the conveyor belt 2 takes place successively until 2 sleeves have been transferred for all the sleeve holders 20 of the conveyor belt. Then the conveyor belt 2 returns to its starting position.
  • the described embodiment can be modified in various ways.
  • the sleeve detached from the sleeve column by the separating device is gripped by a gripper, brought into the conveying position and inserted directly into a sleeve driver 61 of the ascending conveyor 6.
  • the sleeve slide 51 and the sleeve storage table 52 with the transfer means 71 can then be omitted.
