Definitions

  • the present invention relates to an improved device allowing the positioning and the maintenance of a wire support tube during a reeling or reeling operation during which said support (tube) is rotated.
  • Such expandable mandrels are used on many textile machines such as twists, assemblers, cablers ... Given the increase in production speed, weight and diameter of the windings from spinning, it is imperative to have a perfect coincidence of the axes of the mandrel and of the wire support tube as well as a perfect immobilization of these two elements with respect to each other both in operating stroke and during start-up or 'stop.
  • another also very important problem is that of the ease of positioning the support on the mandrel as well as of its extraction, an operation which is sometimes disturbed by the fact that the support tubes are not always perfectly cylindrical, in particular when they are made of cardboard.
  • FIG. 1 illustrates, in perspective, a working position of a twisting machine in which a winding of wire (1) formed on a support tube (2), made of cardboard for example, must be unwound during unwinding to be returned to a spindle (3), with ring and slider, allowing it to communicate a twist.
  • the wire winding (1) is mounted on a support mandrel according to the invention, which will be seen in more detail in the following description, said mandrel being driven in rotation by a motor shaft (4). controlled by any appropriate means (geared motor for example).
  • said mandrel M is constituted, in accordance with the invention, as is apparent from FIGS. 2 and 3, from two elementary sleeves (5a, 5b), mounted facing one another at the end (6) of the drive shaft (4).
  • These two sleeves (5a, 5b) are made of molded plastic, from identical parts and, in the following description, the same references assigned the indices a e b will be used to designate the same elements which characterize their structure.
  • These two sleeves (5a) and (5b) comprise a hub (7a, 7b) allowing their mounting on the end (6) of the drive shaft (4), a bottom (8a, 8b) and a plurality of peripheral fingers (9a, 9b)).
  • the machons (5a, 5b) are mounted in opposition to the end (6) of the shaft (4), so that the peripheral fingers (9a, 9b) are nested one inside the other and bear against the junction area between your fingers of the opposite sleeve. In other words, the fingers (9a) bear against the junction zone (10b) formed between the fingers (9b) of the sleeve (5b) and vice versa for the fingers (9b).
  • One of the machons, (5a) for example, is fixedly mounted on the end (6) of the drive shaft (4) while the other sleeve, (5b) in the present case, is mounted free in translation.
  • a spring (14) is applied between the internal faces of the bottoms (5a) and (5b) and tends to keep the two sleeves normally spaced from one another, so that the stops (11 a, 1 1 b) provided on the underside of each of the fingers (9a, 9b) bear against the ramps (12a, 12b) provided against the bottoms (5a, 5b), which tends to move away from the axis XX of the mandrel the ends of said fingers.
  • the wire support tube is therefore perfectly maintained and centered around the mandrel M.
  • the two sleeves (5a, 5b) When it is desired to install or remove the support tube, the two sleeves (5a, 5b) are brought into the position shown in Figures 2 and 3, that is to say that the sliding sleeve (5b) is pushed back, for example by means of jacks so as to compress the internal spring (14) so that the ends of the flexible fingers are no longer subjected to the action of the ramps and tend to return to their initial position parallel to the axis XX of the mandrel.
  • Such a mandrel of particularly simple design has a very high efficiency, is easy to maintain and assemble and moreover allows automatic self-centering during the positioning of the wire support tubes.
  • the dimensions of the mandrel are determined as a function of the diameter and the length of the support slats.
  • such a type of mandrel is particularly suitable for equipping the unwinding part of a collating-twisting unit, it could be envisaged to maintain the winding support tubes in a similar manner.
