Definitions

  • the invention relates to a method for transporting cops and sleeves between spinning and winding machines in a spinning mill, in which the wound cops originating from the spinning machine are moved to the dishwasher by means of mobile, essentially box-shaped bobbin wagons in which the cops are disordered transported.
  • a winding machine In the spinning mill, a winding machine is usually arranged after several spinning machines. The wound cops produced in the spinning machines are rewound in the winding machine to larger bobbins. As a result, empty spinning tubes are produced in the winding machine, which need to be examined for any remaining threads, sorted out and returned to the spinning machines. So far, the procedure is as follows. After the spinning tubes with residual threads have been sorted out, the usable spinning tubes are placed parallel to one another in specially designed spinning tube containers. The spinning tube containers, which have a width that corresponds approximately to the length of the spinning tubes, have a bottom that can be opened on their underside.
  • the spinning tubes deposited in the spinning tube containers are transported with the containers to the spinning machine and positioned there on the feeding device, after which the bottom of the tube container is then opened.
  • the feed device of the spinning machine successively removes the spinning tubes, which are aligned parallel to one another, from the tube container. So that the sleeves are then automatically attached to the sleeve feed belt of the spinning machine, the sleeves are in This device is sorted so that the large opening of the conical sleeves points downwards.
  • This object is achieved in that the bobbin wagon is also used for the return transport of the sleeves unwound in the winding machines to the spinning machines.
  • This solution has the advantage that no separate container for the transport of the spinning tubes from the Winding machine for spinning machine is needed.
  • the bobbin wagon which is normally used to transport the cops from the spinning machine to the winding machine, is now also used to transport the empty spinning tubes from the winding machine to the spinning machine. In this way, in addition to the special spinning sleeve containers, empty runs of the bobbin wagon from the winding machine to the spinning machines are saved.
  • IM also larger bobbin wagons on the spinning machine, e.g. To be able to empty into a container, it is advantageous if the bobbin wagon is tipped out in a tilting device to remove the sleeves on the spinning machine.

  • the angle of inclination o of the floor to the horizontal is approximately 20 ° in the exemplary embodiment shown here.
  • the storage container 2 is delimited by two side walls 14 and 15, which run on the one hand from above in a funnel-like manner to the bottom 3 and on the other hand also funnel-like towards the front to the vertical conveyors 9 and 9 '.
  • the storage container 12 is divided by a partition 16 into two intermediate stores 17 and 18 assigned to the respective vertical conveyors 9 and 9 '.
  • the height of the partition is only about a third of the height of the two side walls 14 and 15.

In any case, the distance A is smaller than the sum of the smallest diameter d of a sleeve 30 and the width B of a driver strip 10.
  • a threaded pin 32 is screwed into one of the sliding walls 25, but this screw projects slightly beyond the front of the sliding walls. So that the driver strips 10 are not hindered by the threaded pin 32, corresponding recesses are provided in the driver strips 10, which are not shown in the drawing for the sake of clarity.
  • An ejector 33 is arranged above the threaded pin 32 and comprises an ejector pin 35 which can be actuated and moved by means of a pneumatic short-stroke cylinder 34.
  • the ejector 33 is, as will be explained later, connected to a counting device which comprises a light barrier 36 which is attached to the side of the vertical conveyor 9 facing away from the storage container 12 and which counts spinning sleeves conveyed by the vertical conveyor 9.

  • the bobbin wagon 7 is filled with the empty spinning tubes that are produced there. Since the bobbin wagon is larger in all dimensions than the spinning sleeves to be transported, the spinning sleeves are disordered and mixed up in the bobbin wagon 7. The bobbin wagon filled in this way is then moved from the winding machine to the spinning machines, where it is emptied into the storage container 12 together with the lifting and tilting device 19. Since the partition 16 between the two intermediate stores 17 and 18 of the storage container is not as high as the two side walls, the number of spinning sleeves 30 is distributed relatively well between the two intermediate stores 17 and 18, since the spinning sleeves are also above the partition 16 when the storage container 12 is full lie.
  • the driver strips 10, 10 ′ facing the storage container 12 move upward.
  • the unordered pile of spinning sleeves present in the store is mixed until a sleeve parallel to the vertical conveyor is also present on the front edge 31 of the storage container bottom 13.
  • Such a sleeve is then gripped by a driver strip 10 or 10 'and conveyed upwards.
  • This process is repeated until the intermediate stores 17, 18 of the storage container 12 are completely emptied, the obliquely arranged bottom 13 ensuring that all spinning tubes are fed to the vertical conveyors 9 and 9 ', respectively. Now it can happen that two spinning tubes on top of each other rest on a carrier bar 10 or 10 ', but this is not desirable.
  • Such a pair of spinning sleeves passes through the setscrew 32 in the upper region of a vertical conveyor 9 or 9 ', as a result of which the spinning sleeve lying above is pressed a small amount away from the sliding wall 36. This small amount is sufficient for the upper spinning sleeve 30 to become “overweight” and to fall down into the storage container 12 from the lower spinning sleeve.
  • the underlying spinning sleeve is also pressed off the sliding wall by the grub screw 32, but then returns to the sliding wall 26, since the width B of the carrier strips is dimensioned such that the spinning sleeves 30 are not knocked down by the grub screw 32 from the top 28 thereof.
  • Guide bars 44 are provided on the rear wall 38 so that the spinning tubes are centered on the feed channel 41 during the downward transport in the shaft 39.
  • the width of the intermediate store is the distance between the partition 16 and a side wall 14 or 15 in the region of the front edge 31 of the bottom 13 selected so that it corresponds to one and a half times the length of a spinning sleeve 30.
  • the side walls 14 and 15 as well as the partition 16 serve to guide the driver strips 10, 10 ', which have corresponding guide shoulders 45 at their free ends.
  • the spinning tubes While the spinning tubes are being sorted and fed, they are counted by means of the light barrier 36. If now e.g. If the first intermediate store is empty and is only conveyed from the other intermediate store 18, the numerical difference is compensated for as follows.
  • the ejector 33 is actuated, the ejector pin 35 throwing the spinning sleeves off the respective carrier bars 10 and 10'.
  • These thrown-down spinning sleeves 30 pass through the chute 37 into the respective other intermediate store, that is to say into the empty intermediate store 17, which is refilled in this way, so that the other vertical conveyor feeds empty spinning sleeves to the other feed of the spinning machine. In this way, an inaccurate distribution of the spinning sleeves present in the two intermediate stores 17 and 18 in a disordered manner can be compensated for.

  • the wound sleeves are then conveyed out of the machine via the sleeve feed belt 5 and the conveyor belt 6 and get into the bobbin wagon 7
  • the bobbin wagon 7 cops to be put down this is no longer necessary in the device according to the invention, since the bobbin wagon with the lifting and tilting device is slowly pivoted downwards from the position shown in dashed lines in FIG. 1 and finally set down on the floor can, without the cops having to travel larger heights.
  • the loading and disposal of the spinning machines with sleeves or cops with the same transport container, namely the bobbin wagon, can be carried out without any empty paths.

Abstract

Afin de pouvoir insérer automatiquement les bobines sur les bandes de rentrage de métiers classiques à filer, il faut présenter les bobines vides dans leur position correcte. A cet effet, il était nécessaire de transporter les bobines jusqu'au métier à filer dans des récipients mutuellement parallèles. Afin de permettre l'utilisation de n'importe quels récipients pour transporter les bobines entre le bobinoir et le métier à filer, le métier à filer comprend un dispositif ayant un réservoir (12) dans lequel les bobines (30) sont temporairement stockées de manière désordonnée. Le réservoir (12) est relié à un convoyeur vertical (9) pourvu d'une pluralité de baguettes d'entraînement (10) horizontales qui reçoivent des bobines individuelles tirées du tas désordonné de bobines (30) et qui les amènent au dispositif de rentrage (3) du métier à filer dans leur position correcte.
