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, stranding machines. Given the increase in production speed, the weight and the diameter of the windings coming 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 in relation to each other both during the running stroke and when starting or stopping.
  • 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.
  • the invention therefore relates to a new type of mandrel intended to serve as a holding element for a hollow cylindrical support tube around which wire is wound, usable in particular for unwinding said wire on unwinding, said mandrel being mounted on a shaft allowing it to rotate, and it is characterized in that: -
  • the mandrel consists of two elementary sleeves, mounted opposite one another on the drive shaft, said sleeves comprising peripheral fingers regularly spaced from each other, the fingers of a sleeve pressing against the area between the fingers of the other sleeve, at least one of the elementary sleeves being mounted free in translation on the drive shaft and the assembly is subjected to the action of thrust means tending to keep the two sleeves spaced from one another, so that the ends of the fingers tend to move away from the axis of the mandrel and to block the cylindrical support tube disposed around said mandrel.
  • the two elementary sleeves are identical except that the ends of the fingers of one of the sleeves include the stops for the wire support tube; - the elementary sleeves are made of plastic, by molding; - Means tending to keep the two elementary sleeves separated from one another are constituted by a spring.
  • 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 at the unwinding to be returned to a spindle (3), ring and slider, 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 shown in Figures 2 and 3, two elementary sleeves (5a, 5b), mounted opposite 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 remainder of the description, the same references assigned with 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 the 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 (11a, 11b) 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 spread the relative to the axis XX of the mandrel 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 (11) so that the ends of the flexible fingers are no longer subjected to the action of the ramps and tend to resume 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.
