Definitions

  • the invention relates to a machine for separating strings of tubular textile articles assembled by fragile threads and optionally turning said strings beforehand.
  • Another technique consists in using fusible wires which are destroyed by a heat treatment. This technique however entails risks of deterioration of the article itself and generally only provides a partial elimination.
  • This technique of knitting in strings can relate to various textile articles such as sweater sleeves. for example, but more particularly relates to the manufacture of socks.
  • the strings of socks are generally turned over either before or after the separation of the articles while the next operation consists in closing the points on a sewing or re-stitching machine.
  • the invention provides a machine for breaking apart strings of tubular textile articles, such as strings of socks, assembled by fragile threads. These strands may also, in certain cases, be soluble or fusible, so as to be able to eliminate residues which may remain on the articles, after the breakage of said wires.
  • the machine is remarkable in that the transport tube is arranged in a known manner to receive a rosary by threading, by means possibly with a drive roller, so that said chain can be turned over in the tube and then attracted by the suction generated by the vacuum cleaner.
  • the vacuum cleaner is formed by a suction means which communicates with a chamber arranged around the tube which has an openwork wall at this location in the manner of a strainer so that the rosary is applied by suction against the perforated internal wall of said tube.
  • the overpressure means is formed by a compressed air supply, controlled for example by a solenoid valve and connected to the tube by an oblique connection inclined towards the valve which opens under the action of compressed air when said supply is open.
  • the separator can be formed by two successive pairs of rotating rollers, the linear speed of rotation of the second pair being greater than that of the first so that the chain is driven between the rollers of each pair and the difference in speed allows to the rollers of the second pair to exert sufficient traction to break the assembly threads of the articles of the rosary.
  • the electrical means provided for actuating the overpressure means during the path of the rosary comprises a feeler, disposed in the transport tube before the vacuum cleaner and which electrically controls the overpressure means while the means d 'stop of the latter is formed by an electrical contact controlled by the separator when the latter receives the chain.
  • the probe advantageously controls the overpressure means by means of a bi-stable or self-powered relay on which the electrical stop contact also acts.
  • the overpressure means comprises a compressed air supply controlled by a solenoid valve
  • the bi-stable relay acts directly on it.
  • the drawing schematically shows an embodiment according to the invention which presents a transport tube 1 on which is strung a chain 2, of socks for example, by means of the drive roller 3.
  • a suction means 4 communicates with a chamber 5 arranged around the tube 1 which has at this location a wall la, perforated in the manner of a strainer.
  • the lower end of the tube 1 is provided with a valve 6 comprising a movable shutter valve 7.
  • a compressed air supply 8 controlled by a solenoid valve 9 is connected to the tube 1 by an oblique connection 10 inclined towards the valve 7.
  • a separator 11 comprising two superposed pairs of rotary rollers 12 and 1 3.
  • the rollers rotate in the direction indicated by the arrows at different linear speeds from one pair to the other, the rollers 13 having a speed slightly higher than that of the rollers 12.
  • An electric probe 14 is placed in the tube 1 above the chamber 5.
  • This probe acts via a bi-stable or self-powered relay, not shown, on the solenoid valve 9.
  • At least one roller of each pair can deviate from its opposing roller while it is biased towards it by an elastic means such as a spring 15, which acts on a support arm 16 of said roller.
  • An electrical contact 17 is further arranged to be controlled by the movement of the arm 16 of the upper pair of rollers 12 when the latter move away from one another. This contact 17 acts on the solenoid valve 9 for example by means of the above-mentioned relay.
  • the operation is simple to understand.
  • the suction means 4 creates in the tube 1, through the chamber 5, a depression which causes the closure of the valve 7 and the suction of the chain 2, the end of which is introduced, after turning (see the arrow F), in the end orifice of the tube 1.
  • the chain 2 is thus sucked up to the level of the chamber 5.
  • the chain activates the probe 14 which controls, via the aforementioned relay, the opening of the solenoid valve 9 of the compressed air supply 8.
  • the compressed air thus released arrives in the tube 1 by the connector 10 and generates an overpressure which, on the one hand, causes the opening of the valve 7 of the valve 6 and, on the other hand, creates, upstream, an additional depression in the tube 1, so that the chain 2 is sucked towards the fitting 10 and pushed through the valve 7 between the pair of rollers 12.
  • the rosary which can be crumpled or in accordion at the level of the chamber 5 undergoes a smoothing due to the retention of the posterior part of the rosary by the suction means 4 and a suction of the anterior by diet 8.
  • the embodiment described is given by way of nonlimiting example and many variants can be imagined without departing from the scope of the invention.
  • the invention relates not only to strings of socks, but also to all kinds of tubular articles comprising a fragile separation thread.
  • the invention obviously makes it possible to separate said strings without necessarily having to turn them over beforehand.
