  • the resulting loose thread end is picked up and removed via the suction device.
  • the thread is taken from a Fa denology.
  • the clamping plate When the clamping plate rotates, a thread section of the incoming thread located on the edge of the clamping plate falls into the incision and is thus caught by the catch.
  • the clamping plate has a clamping and cutting mechanism, which is not described in detail, so that the incoming thread can be fixed and wound onto the winding tube.
  • the thread itself can be actively grasped by a traversing thread guide, whereupon a new bobbin travel begins.
  • Another possibility is to hold the thread in that it is carried along by friction around the catch hook. This possibility was also discarded because the thread does not remain reliably on the catch hook due to the lack of fixation or soiling occurs on this over the long term, for example through thread remnants in the event of thread breakage.
  • annular thread catching body made of a elastic material with at least one catch nose arranged so that it cannot rotate. Due to the elasticity of the material, the catch that has gripped the thread can move away regardless of the thread thickness and the nature of the thread, so that damage to the thread can be ruled out.
  • the side facing away from the tip of the catch nose is secured against lifting off the face of the centering plate. As a result, the caught thread can be prevented from slipping through between the thread catcher and the center plate.
  • the document DE 43 34 813 A1 discloses a winding device for winding a continuously tapered thread with two centering plates, between which a Spu lenhülse is clamped and one of which has a catch groove for the thread.
  • a ring-shaped collar extending over the Hül senrand is provided.

  • the mass of the catch device compensating mass is provided, which is formed in a circumferential position offset from the catch device.
  • the thread If the thread is clamped in the centering plate or in the chuck of the centering plate, the thread must be actively pulled out of this clamping when the bobbin winding is completed, otherwise there is a risk that the wound bobbin will not unroll evenly or be inclined because it is still on fixed thread gets stuck. It is therefore the object of the present invention to provide a device and a method of the type specified above, which allow a reliable thread clamping during thread catching with an automatic bobbin change without major structural effort, without impairing the function by dirt such as adhering thread remnants if the thread breaks, it is to be feared.

  • a suitable thread clamping point 14 is formed between the first ring segment 16 in the thread running direction A after the catch hook 9 and the edge or corner formed between the casing side 31 and the end face 33 of the winding tube of FIG.
  • FIGS. 5 to 7 schematically show three successive steps of an embodiment of the method according to the invention, the winding tube 3 with the centering plate 52 having the catch hook 9 being shown in a side view.
  • FIGS. 5 to 7 The rotation of the winding tube 3 and the centering plate 52 is indicated in FIGS. 5 to 7 by an arrow on the centering plate 52.
  • FIG 5 a step of an embodiment of the method according to the invention is shown schematically in which the winding tube 3 shown in side view with the centering plate 52 having the catch hook 9 is brought to the thread 2 running between the traversing thread guide 17 and the thread suction 18.
  • the thread 2 fed in via the traversing thread guide 17 from a fixed feed position is first sucked off to the rear via a thread suction device 18 and the empty winding tube 3 is positioned between the traversing thread guide 17 and the thread suction device 18.
  • the thread 2 is initially not yet in contact with the centering plate 52.
  • the application lever 19 is movably mounted parallel to the axis of rotation R of the winding tube 3. Both the axis of rotation R of the flushing sleeve 3 and the direction of movement of the contact lever 19 protrude into the plane of the drawing in FIGS.
  • the application lever 19 When looking at FIG. 5, the application lever 19 is located behind the thread run of the thread 2, so that when it moves in a subsequent step of the embodiment of the method according to the invention shown, it is out of the image plane towards the viewer towards the thread 2 in the direction of the hook 9 having the catch Center quarter lers 52 pushes. As a result, the thread 2 arrives in a position in which it crosses the centering plate 52 having the Fangha ken 9.
  • FIG. 6 shows a step of this embodiment of the method according to the invention following the method step shown in FIG. 5, in which the thread 2 was picked up by the catch hook 9 and guided into a thread clamping gap beginning behind the catch hook 9, which opens into the thread clamping point 14, where the thread 2 was finally clamped.
  • the clamped thread 2 is initially still sucked from the thread suction 18 till.
  • FIG. 6 The cutting of the clamped thread 2 in a step following the process step shown in FIG. 6 of this embodiment of the process according to the invention is shown in FIG.
  • annular groove 54 and an inlet bevel 55 delimiting it are arranged on the outside of the centering plate 52 facing away from the winding tube 3.
  • a thread knife 21 is located on the annular groove 54.
  • the severed thread 2 remains in the thread clamping gap 14, while the remainder of the thread 2 is sucked off by the thread suction device 18.

Abstract

La présente invention concerne un dispositif (1) d'enroulement d'un fil (2) sur une bobineuse et un procédé d'enroulement d'un fil (2) sur une bobineuse. La bobineuse comprend au moins un manchon de bobine (3) et un porte-bobine (4), qui comporte deux plaques de centrage (51, 52) disposées à l'opposé l'une de l'autre, ayant une distance axiale réglable l'une par rapport à l'autre, pour tendre le manchon de bobine (3), les plaques de centrage (51, 52) présentant chacune un cône de centrage (7) qui se met en prise dans une extrémité de manchon de bobine ouverte, un crochet d'arrêt fixe (9) pour arrêter le fil (2) est disposé dans l'une des plaques de centrage (52), ledit crochet d'arrêt étant orienté dans la direction circonférentielle de ladite plaque de centrage, et la plaque de centrage (52) ayant le crochet d'arrêt (9) comprenant un cône externe (8) qui chevauche le diamètre externe de l'extrémité de manchon de bobine (6), un côté intérieur du crochet d'arrêt (9) étant formé par un évidement en forme de nez (11) disposé dans le cône externe (8), et un point de serrage de fil (14) étant formé entre une paroi interne (12) du cône externe et un bord entre le côté latéral (31) et la face d'extrémité (33) de l'extrémité de manchon de bobine (6).
