Definitions

  • the invention relates to a method for feeding empty spinning tubes originating from a winding machine to a drawing-in device of a spinning machine, to which drawing-in device the spinning tubes are to be presented aligned parallel to one another. Furthermore, the invention relates to a device for feeding empty spinning tubes to a drawing-in device of a textile machine winding the empty spinning tubes with yarn, in particular for carrying out the previously specified method.
  • 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 placed in the spinning tube containers are arranged with the containers transported to the spinning machine and positioned there on the feed device, after which the bottom of the sleeve 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 placed on the sleeve feed belt of the spinning machine, the sleeves are sorted in this device so that the large opening of the conical sleeves points downwards.
  • This solution has the advantage that no separate container is required for the transport of the spinning tubes from the winding machine to the spinning machine. It is also possible to use the bobbin wagon, which is normally used for the transport of the cops from the spinning machine to the winding machine, for the transport of the empty spinning tubes from the winding machine to the spinning machine, since the spinning tubes are only aligned in the correct position on the spinning machine. In this way, in addition to the special spinning sleeve containers, you also save empty runs of the bobbin wagon from the winding machine to the spinning machines.
  • the unoriented spinning sleeves are temporarily stored and aligned separately, the respectively aligned sleeves being counted, and wherein "if there is a numerical difference, the surplus spinning sleeves are automatically returned to the other intermediate store, which has the advantage that, if necessary, an equal number of spinning sleeves is fed to both drawing-in devices of the spinning machine without the operator having to pay particular attention to this.
  • the object underlying the invention is achieved in that the Textile machine at least one buffer in the form of a container is provided, in which the spinning sleeves can be inserted in the unoriented state and that one of the container walls is at least partially designed as a vertical conveyor with an upward conveying direction, on which carrier bars horizontally aligned and parallel to one another and spaced apart from one another are provided.
  • This device is particularly suitable for carrying out the method according to the invention, since the empty spinning tubes originating from the winding machine e.g. can be transported to the spinning machine in a disordered state with the bobbin wagon and dumped there into the storage container.
  • the vertical conveyor which feeds the empty spinning tubes to the feeding device of the spinning machines, also aligns the spinning tubes in a parallel arrangement to one another. This is done in that the vertical conveyor forms a container wall and is provided with carrier bars which engage in the pile of empty spinning sleeves present in the storage container and mix these continuously until a spinning sleeve comes to rest on a carrier bar, which is then conveyed out of the storage container by the vertical conveyor becomes.
  • the vertical conveyor thus has a dual function.
  • the container can have a bottom surface that is inclined downward toward the vertical conveyor.
  • the inclination of this floor surface means that spinning sleeves are always in contact with the vertical conveyor and are mixed or taken along by the carrier bars. It has proven to be advantageous if the angle of inclination of the floor surface, measured relative to the horizontal, is approximately between 10 ° and 25 °, preferably 15 ° and 20 °.
  • the container can furthermore have two opposite side walls which converge in the direction of the container bottom and in the direction of the vertical conveyor. As a result, the pile of spinning tubes present in the container is fed to the vertical conveyor practically in a funnel-like manner, so that several spinning tubes are always involved in the mixing process up to the last spinning tube.
  • the distance between the side walls in the area of the vertical conveyor in the vicinity of the container bottom is greater than the length of a spinning tube and less than one and a half times the length of a spinning tube. This distance range has been found to be favorable in order to accelerate the separation of the spinning tubes by the vertical conveyor.
  • a distance can be provided between the edge of the container bottom facing the vertical conveyor and the vertical conveyor that is greater than the width of a carrier bar and smaller than the sum of the width of a carrier bar and the smallest diameter of a spinning tube.
  • the length of a carrier bar is greater than the length of a spinning tube and less than one and a half times the length of a spinning tube, on the one hand it does not depend on the exact position of a spinning tube in order to position it correctly To be taken vertically, while on the other hand a mutual jamming of the spinning sleeves is prevented.
  • the vertical conveyor has at least one circumferential belt to which the carrier strips are fastened.
  • blocks are cast onto the belt, on which the carrier strips are screwed tight.
  • the vertical conveyor has two belts designed as toothed belts.
  • the belt or belts are narrower than the driver bars and that the belt or belts laterally from fixed sliding walls are framed, on which the driver strips are slidably held by the belt.

  • the spinning sleeves lying directly on the carrier bars also lie directly on the sliding walls, which already counteracts the tendency that two spinning sleeves are transported one above the other.
  • a rear wall is attached to the side of the vertical conveyor facing away from the container and with its conveying direction pointing downwards, the back wall of which is smaller than the smallest diameter of a spinning tube.
  • a shaft is formed on the rear side of the vertical conveyor, in which the spinning sleeves fall onto the underside of the front driving bar in the transport direction and are guided downward in the shaft according to the speed of the vertical conveyor.

Although it would also be possible to provide two separate containers for the respective vertical conveyors, it is preferred that a common container is provided which has a dividing wall through which an intermediate store of approximately the same size is assigned to each of the vertical conveyors. This has the advantage that the unordered spinning sleeves can be emptied from a trolley into a container for loading the device without having to pay attention to a special distribution of the spinning sleeves.
  • the height of the partition is approximately one third of the height of the side walls of the container.

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 les 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.
