Definitions

  • the present invention relates to a combined device for turning over strings of socks, stockings and similar footwear knitted into continuous strings, and for supplying strings of a sock separation machine.
  • the footwear is knitted in continuous strings by being connected to each other by a frangible or destructible yarn, for example a fusible yarn which can be destroyed by a heat treatment with steam.
  • a frangible or destructible yarn for example a fusible yarn which can be destroyed by a heat treatment with steam.
  • This method of inverting the strings and feeding the separation machine involves manual work which is not only tedious, but also tedious due to the vapor atmosphere prevailing in the zone of connection of the tubes to the separation machine, zone in which the personnel responsible for turning the chain and feeding the separation machine must enter when connecting each tube to the separation machine.
  • the capacity of the separation machine is only very partially used because manual feeding cannot ensure continuous and optimal feeding of the machine.
  • the present invention relates to a combined device for turning over strings of socks and supplying strings of a sock separation machine, making it possible to simplify manual work, make this work much less painful, and optimize the operation of the separation machine, that is to say to increase its output.
  • the combined device for turning over strings of socks and supplying strings of a sock separating machine comprises, according to the invention, a threading tube supported at a first of its two ends, for manual threading d 'a rosary on said tube by the second open end of the latter.
  • This device further comprises a plurality of parallel pipes for transporting and storing strings, the first ends of which are arranged opposite the first end of said threading tube and the second ends of which are connected to the separation machine.
  • This device furthermore comprises a distributor member making it possible to connect the first end of the threading tube selectively to the first end of one of said transport and storage pipes.
  • the device comprises means for creating a depression in said pipes, in the vicinity of their second ends, and thus producing in said pipes a suction effect which is propagated, via the distributor member, in said threading tube.
  • the first ends of the transport and storage pipes are distributed over a circle and the dispensing member is constituted by a member mounted in rotation about an axis aligned with the axis of the threading tube.
  • a first end of said dispensing member is permanently connected to the first end of the threading tube and its second end can, by rotation of the dispensing member, be selectively brought into coincidence with and connected to the first end of any of the transport and storage pipes.
  • the device advantageously comprises a roller whose axis is perpendicular to the axis of the threading tube, which is mounted movable back and forth so as to be able to be brought in contact with and out of contact with the threading tube, and which can be rotated in the direction of threading of the string on the tube.
  • the rotation of the dispensing member can be done manually, but it is advantageous to provide a motorized member such as a rotary actuator for rotating the dispensing member.
  • each transport and storage pipe can be transparent to allow the operator to determine which pipe is empty and can therefore be connected to the threading tube to receive the next string.
  • each transport and storage pipe comprises a detector of the presence of strings and the dispensing member is controlled so that when the threading tube is connected to a pipe, the the dispensing member remains locked in position until the detector of this pipe detects the presence of the chain and is then controlled so as to connect the threading tube to another pipe whose detector signals the absence of a chain.
  • each transport and storage pipe comprises, near its end connected to the separation machine, an injector controlled by the detector of this pipe to propel the rosary detected using a jet, for example of compressed air, in the separation machine.
  • each of these pipes advantageously comprises, at its connection end to the separation machine, a valve opening to allow passage of the rosary under the action of the injector and then closing under the action of vacuum.
  • the steam chamber A of a machine for separating socks into strings is followed by an evacuation and drying mat B opening into a receiving tank C for the separate socks.
  • the steam chamber A is supplied in strings of socks connected to each other by a thermofusible separation wire, destroyed by the heat treatment undergone in the steam chamber A.
  • the device for turning over the strings of socks and feeding the steam chamber A of the separation machine comprises a tube 1, one end 2 of which is mounted on a base 3 so that the tube 1 is horizontal and supports false. Below the tube 1 is installed a roller 4, the axis of rotation of which is perpendicular to the axis of the tube 1.
  • the roller 4 comprises a motor, not shown, for rotating, as well as a means, not shown, for example. a pedal, making it possible to bring the roller 4 into contact with and out of contact with the tube 1.
  • the member 5 comprises an S-shaped tube 6, one end of which 7 is rotatably connected to the end 2 of the tube 1, in alignment with the latter .
  • the other end of the tube 6 is rigidly connected to an eccentric axial hole of a rotary plate 8, the axis of which also coincides with the axis of the tube 1.
  • a rotary cylinder 9 mounted on the base 3 acts in rotation on the plate 8 for the modification of the angular position of the distributor member 5.
  • the plate 8 of the distributor member 5 cooperates with a fixed plate 10.
  • the plate 10 has five axial holes distributed at regular angular intervals on a circle whose radius corresponds to the eccentricity of the passage hole of the plate 8.
  • two trays 12 and 13 containing the strings of socks to be returned the tray 12 being the tray during work and the tray 13 serving as a reserve tray.
  • a nozzle 14 for blowing hot air or steam is disposed in the vicinity of the tube 1 to allow the operator who stands on one side of the tube 1 to cut the strings contained in the tubes to a determined length.
  • trays 12 and 13 Finally, a window 15 is placed on the side of the tube 1 opposite the operator, this window allowing the operator to see the hidden side of the pipe 1.
  • each of the five pipes 11 comprises, at a distance from its connection end to the steam chamber A, a detector 16 sensitive to the presence of a chain of socks in the pipe 11.
  • each pipe 11 close to the steam A, each pipe 11 comprises a strainer 17, all the strainers 17 being connected to the suction side of a turbine 18 whose discharge side is connected to the mat B of the separation machine for drying the socks leaving the chamber steam A.
  • each pipe 11 comprises an injector 19 connected by a valve 20 to a source of compressed air, the injectors 19 being oriented in the direction of the steam chamber A.
  • each pipe 11 has a valve 21 which closes under the effect of the vacuum created by the turbine 18 in the pipes 11, but opens under the effect of the jet of compressed air supplied by the injector 19.
  • valves 20 which control the supply of compressed air to the injectors 19 are time-controlled by the detectors 16 so that each injector 10 is actuated by the detector 16 of the corresponding pipe laying after this detector has detected the presence of a chain of socks in the pipe in question and after this chain has had time to settle between the strainer 17 and the detector 16.
  • the detectors 16 are also involved in the control of the rotary actuator 9 of the distributor member 5 in the sense that when the presence of the string removed by suction from the tube 1 is detected by the detector 16 of the pipe 11 connected by the member distributor 5 to the tube 1, which indicates that the chain in question is contained in the hose 11, the jack 9 actuates the distributor member 5 to move the latter into a position in which it connects the tube 1 to another hose 11 empty, that is to say a pipe whose detector 16 detects the absence of a chain.
  • the operator puts a chain on the tube 1 by engaging one end of the chain on the free end of the tube 1 and advancing it to the roller 4 which, brought into contact with the tube, then ensures by its rotation the complete threading of the chain on the tube 1.
  • the rotary actuator 9 actuates the distributor member 5, under the control of the detectors 16, to bring the distributor member 5 into a position in which the latter connects the tube 1 to a pipe 11 does containing no rosary, so that the depression established in the pipe 11 in question by the turbine 18 creates a suction effect at the free end of the tube 1.
  • the operator After having put the roller 4 out of contact with the tube 1, the operator brings the other end of the chain to the free end of the tube 1, so that the chain is progressively drawn inside the tube 1 and returned.
  • the rosary progresses in the pipe 11 until reaching the detector 16 which, after compaction of the rosary between the strainer 17 and the detector, actuates the injector 19 to propel the rosary in the steam chamber A whose introduction rollers are not shown are responsible for passing the string in the steam chamber, and to trigger the rotation of the distributor member 5 in order to bring the latter into another angular position in which it connects the tube 1 to another pipe 11 whose detector 16 has detected the absence of a chain.
