Definitions

  • the present invention relates to a device and a transfer installation, in particular between a storage and at least one form of a forming station or sewing or ironing, knitted tubes constituting footwear, such as tights, knee-high, sock, each tube presenting at a end a point and at the other end a strip or belt.
  • the blanks are pre-positioned, hears in particularly the axial positioning of the tip, the band or belt and the tube demarcation on the form; this rotational positioning being in particular required for asymmetric tubes or in the presence of patterns on the tubes for a relative and precise positioning of two tubes between them, these tubes being intended, after assembly, to constitute an article of footwear.
  • These operations transfer are carried out so far by means of a transfer member made of a folded sheet affecting the general shape 'a contoured parallelepiped as illustrated in particular the EP patent A-0.508.014.
  • This transfer organ generates significant tension of the tubular blank on the its entire length causing damage to the tip of the tube, this tip being unsuitable for bear as much tension as the tape or tube belt.
  • a body transfer must be adapted to the dimensions each time shapes of adjacent posts.
  • An object of the present invention is to provide a device and type transfer facility supra whose designs allow to preserve the tip of the tube by limiting the tension exerted on this last compared to the stress on the tube band or belt.
  • Another object of the present invention is to provide a transfer device and installation of the type supra whose designs / allow to adapt to variable dimensions of form, the operation of unloading the tube on the form which can further allow the tube to unravel.
  • the invention relates to a device for transfer, in particular between a storage station and least a form of a shaping or sewing station or ironing, knitted tubes constituting articles footwear, such as tights, knee-highs, socks, each tube having a tip at one end and at the other end a band or belt, device characterized in that it consists of at least one pair, preferably at least two pairs, of pins to parallel arrangement on at least part of their length, the pins of a pair of pins being contra-angled counter-rotating pins to present, during their rotation training, a portion to substantially constant spacing between said pins and a portion with variable spacing so as to exert, on the tubular element, a variable tension helping to load on spindles, positioning spawning and belt on pins, and at spindle unloading.
  • the design of the bent pins i.e. angled at least twice so allows, when their drive in rotation, to have a share of a first portion of the pins intended to receive the part of the tip of a tube threaded on the spindle, the spacing is kept substantially constant by position moved away from the pins, on the other hand from another portion of the pins during a approximation or spacing of the pins performed with variable spacing so as to exert on the tubular element, in particular at the level of the band or belt part of this element, tension variable within a range of variable amplitude so as to assist with spindle loading, positioning of the belt on the spindle and spindle unloading.
  • such pin design facilitates tube unloading on the form this will be described below.
  • the design of such a transfer device is simplified since only one drive mechanism in rotation is necessary to allow training in rotation of the two counter-rotating spindles.
  • the device and the installation, objects of the invention are intended for allow the transfer of constituent knitted tubes 1 footwear, such as tights, knee-highs, sock, in particular between a storage post P and at least one form F1 of an F training or sewing or ironing said tubes.
  • This post P of storage can affect a large number of forms.
  • this P storage station is constituted by an opening box whose detail of realization is more particularly described in the Patent EP-A-0.508.014.
  • the tubes 1 are brought to this opening box after undergoing an operation bulk sampling in a container and one step orientation so as to ensure loading of the tube 1 on the transfer device tip 1A in front of tube 1.
  • the tube 1 thus oriented point 1A in front must be transferred for example to an F1 form presenting generally in the form of a clamp incorporated in a post F whose functions can be diverse.
  • this post F can either constitute a forming or sewing or ironing or closure of the tube tips. It is necessary that during this transfer the tube 1 is subjected to positioning steps so as to be transferred in a predetermined position always identical on the F1 form to allow optimized realization of operations on this station F.
  • the transfer between these two posts is done by means of in transfer device consisting of at least spindles 2 available in parallel on at least part of their length.
  • FIG. 4 illustrates, in top view, the general shape of the pins 2.
  • such 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.
  • the pins of a pair of pins 2 are pins double-angled at least twice.
  • the elbows have respectively represented in 3A and 3B in the figure 4.
  • These spindles are also rotary spindles rotated counter-rotating.
  • a portion 2A with substantially spacing constant between said pins and a portion 2B to variable spacing between said pins The part 2A with substantially constant spacing of the pins is intended to receive the tip part 1A of the blank 1 while the variable spacing portion 2B of the pin is intended to receive the strip part or belt 1B of the tube 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 spindle holder 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 kinematic movement secured to the pins.
  • each pin 2 is a tubular pin.
  • the part of the spindle extending between a free 2C end and a portion 3A, 3B angled is mounted free at rotation, the rest of spindle 2 being rotatable controlled by means of the drive mechanism 9 in rotation.
  • the elbow 3B and the free end 2C it can be provided, in the body of the spindle, for example a needle socket.
  • the function of this free rotation assembly will be described below.
  • Each pair of pins 2 thus produced is mounted on a spindle holder 4 including a mechanism 9 counter-rotating drive of spindles 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 carriage is preferably mounted on a carousel 5, for the transfer of the knitted tubular elements 1 of peer to peer.
  • pins 2 of a pair of pins respectively affect the shape general crank.
  • the transfer installation here consists of a plurality of spindle transfer devices 2, in the occurrence of four transfer devices, each transfer device here being itself made up of two pair of pins.
  • Each transfer device is movable by means of a device suitable such as a carousel 5 so as to cooperate, during its movement, with a plurality of positions represented in P, P1, F, E.
  • post P corresponds to the post of parallel loading of two tubes 1 threaded respectively on a pair of pins 2 of the device transfer. This transfer device is then moved via carousel 5 to a post P1 says positioning station.
  • At least part P, P1 of these stations are equipped with a trolley (s) 6 fitted with friction or pinching members 7 likely to come into contact with the tubes 1 threaded on pins 2 to position axially at minus the belt 1B of the tube 1 on said pins 2, and / or members 8 for rotating a portion of pins 2 to obtain a radial orientation of the tubes 1 knitted on the pins 2.
  • the transfer each consisting of two pairs of pins 2, are mounted on a carousel 5 common to all transfer devices. Carousel 5 therefore brings, during a rotation, check transfer device in front of the four stations supra.
  • the transfer device is positioned in the vicinity of post P, also called post loading tube (s) or storage station bulk tubes can be loaded of tube (s) point 1A forward on the device transfer.
  • post P also called post loading tube (s) or storage station bulk tubes
  • tube (s) point 1A forward on the device transfer.
  • the transfer operation can be carried out via the 6 fitted carriages friction members 7 constituted, in the example shown, by rollers.
  • FIG. 1 illustrates the positioning of the carriage 6 at the end of the outward travel.
  • the axial positioning of the tube 1, in particular of the belt 1B of tube 1 on pins 2, can be detected using appropriate cells.
  • the spindle holder 4 constituted here by a carriage, moves in direction of carousel 5 to bring back the device transfer to initial position. Carousel 5 can then train the transfer device on a quarter turn and bring this transfer device to neighborhood of post P1, called positioning station.
  • This post is only active when a tube has been loaded incorrectly or badly positioned. It can then be evacuated to the level of this post. In this case, the pins were not close to 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 aspirated 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. Thanks to the design of the transfer device, this transfer can be done in seconds while ensuring precise positioning of the tube on the form F of the forming or ironing or sewing station. All of these operations can be carried out in an extremely reduced space due to the compactness of installation.
