  • the tube 1 thus oriented tip 1A forward must be transferred for example to an F1 form presenting itself generally in the form of a clip incorporated into a station F whose functions can be various.
  • this station F can constitute indifferently a forming or sewing or ironing station or closing of the tips of the tube. It is necessary that during this transfer the tube 1 is submitted to positioning steps so as to be transferred in a predetermined position always the same on the F1 form to allow optimized realization of operations on this item F.
  • FIG. 4 illustrates, in a view from above, the general shape of the pins 2.
  • a transfer device has two pairs of pins, each pair of pins being intended for receive a tube threaded on said pins of the pair of pins.
  • pins of a pair of pins 2 are pins bent at least twice.
  • Elbows have respectively shown in 3A and 3B in the figure 4. These pins are also rotating pins rotated in a contra-rotating manner.
  • a portion 2A substantially spaced constant between said pins and a portion 2B to variable spacing between said pins The part 2A at substantially constant spacing of the pins is intended to receive the tip portion 1A of the blank 1 while variable-gauge portion 2B pins is intended to receive the band portion or tube 1B belt 1.
  • the free end of the pins is represented in 2C.
  • the end of the pins intended to be connected to a drive mechanism in rotation incorporated in a pin carrier is shown in 2D in Figure 4.
  • the drive mechanism in rotation of the pins, shown at 9 in the figures, is arranged to allow movement kinematically secured to the pins.
  • each pin 2 is a tubular pin.
  • the part of the pin extending between a free end 2C and a portion 3A, 3B against-bent is mounted free to rotation, the rest of the spindle 2 being rotated commanded by means of the training mechanism 9 rotation.
  • the spindle extending between the elbow 3B and the end free 2C it can be expected, the elbow 3B and the free end 2C, it can be provided in the body pin, for example a needle socket.
  • the function of this free rotational assembly will be described below.
  • Each pair of pins 2 thus produced is mounted on a spindle holder 4 including a mechanism 9 controlled contra-rotation drive of the pins 2 in the direction of approximation or spacing pins 2 as mentioned above.
  • this spindle holder 4 consists of a cart moving back and forth.
  • This trolley is preferably mounted on a carousel 5, for the transfer of the knitted tubular elements 1 of peer-to-peer
  • the pins 2 of a pair of pins respectively affect the shape general crank.
  • the transfer facility here consists of a plurality of pin transfer devices 2, in the occurrence four transfer devices, each transfer device being here itself constituted of two pair of pins.
  • Each transfer device is movable via a device such as a carousel 5 so as to cooperate, during his travels, with a plurality of positions represented in P, P1, F, E.
  • position P corresponds to the position of parallel loading of two 1-threaded tubes respectively on a pair of pins 2 of the device transfer.
  • This transfer device is then moved through the carousel 5 to a post P1 says positioning station.
  • At least a part P, P1 of these stations are equipped with trolley (s) 6 provided with 7 friction or pinch members likely to come in contact with the tubes 1 threaded onto pin 2 to position axially at minus the belt 1B of the tube 1 on said pins 2, and / or organs 8 for rotating a portion of pins 2 to obtain a radial orientation of the 1 knitted tubes on the pins 2.
  • transfer each consisting of two pairs of pins 2, are mounted on a carousel 5 common to the set of transfer devices.
  • the carousel 5 bring, during a turn, check transfer device in front of the four posts supra.
  • the transfer device When the transfer device is positioned in the vicinity of the post P, also called post loading the tube (s) or storage station bulk of the tubes, it can be loaded of tube (s) point 1A forward on the device of transfer. Because the installation has, for one transfer device, two pairs of pins positioned side by side, two tubes 1 are transferred simultaneously.
  • the transfer operation can to be carried out by means of the carriages 6 equipped of friction members 7 formed in the example represented by rollers.
  • FIG. 1 illustrates the positioning of the carriage 6 at the end of the race.
  • the axial positioning of the tube 1, in particular of the 1B tube 1 belt on pins 2 can be detected by means of appropriate cells.
  • the carriage 4 pin holder is brought back to its position initial. Pins 2 can then be discarded to exert maximum tension on tube 1 as illustrates it in FIG. 5C.
  • the carousel 5 operates a new quarter turn to bring the transfer device in the vicinity of the loading corresponding to the unloading of the tube 1 on a form F of any position such as a post of sewing, forming, ironing, closing tip or other. Again the design of the device is particularly interesting for proceed with this unloading operation. Indeed, as shown in Figure 5D, the pins of a pair pins can be positioned on either side of the form F to then be approximated by rotational drive as shown in Figure 5D.
  • the carousel can then perform again a quarter turn to bring the device to transfer to the vicinity of evacuation station E.
  • This post is active only when a tube has been incorrectly loaded or poorly positioned. It can then be evacuated of this post. In this case, the pins were not near the unloading station. It follows that these pins are still in the separated position. It is enough then bring the pins together to get by gravity an evacuation of the tube 1 of the pins 2. These tubes 1 are then sucked by a suction box and fall back into a storage container. A new transfer operation can then begin by bringing the transfer device to the loading. A new transfer cycle begins again.
  • this transfer can be done in a few seconds while ensuring a precise positioning of the tube on the form F of the forming or ironing or sewing station. All of these operations can be performed in an extremely small space due to the compactness of installation.
