Definitions

  • the present invention relates to a method for automatic orientation of hosiery articles such as socks, knee socks or the like with respect to a predetermined plane.
  • the invention relates to a device that carries out this method.
  • Such a device even if it is technically effective, causes a high energy consumption due to the introduction of the air flow, and furthermore a difference in the flow rate of air is required depending upon the type of knitting quality of the socks.
  • a process of orientation of socks begins with the picking up the same from a special container. These are put automatically or manually in a random way on substantially cylindrical elongated supports, i.e. without taking care of their orientation.
  • the elongated support has at least one cylindrical portion.
  • the sock even if stretched elastically in order to match the shape of the support, has a protrusion oriented towards outside at the heel.
  • the rotation is effected of the sock same with respect to the axis of the support, in order to detect the protrusion of the heel according to a tangential longitudinal direction, by using optical sensors.
  • rollers tangential to the support which is kept still.
  • the latter is as smooth as possible, whereas the rollers are coated of a friction surface, so that a relative movement of tangential circumferential rotation between sock and support is created.
  • the presence of the sock on the elongated support for orientation purposes is associated to steps of qualitative control of the same by an operator.
  • the integral rotation of the support and of the sock is provided, according to an angle of at least 180°, so that the operator can see all its surface without moving or using mirrors.
  • FIGS. 1A and 1B show two views of a stretched sock, seen according to two orthogonal longitudinal planes
  • FIG. 2 shows a view of a stretched knee sock
  • FIG. 3 shows an elongated support on which the sock or the knee sock of the previous figures has been put;
  • FIGS. 4A and 4B show the sock of FIGS. 1A and 1B put on the support of FIG. 3 and in two different positions of angular rotation;
  • FIGS. 5A and 5B show the knee sock of FIG. 2 put on the support of FIG. 3 and in two different positions of angular rotation;
  • FIG. 6 shows a top plan view of a rotation device of the sock on the elongated support
  • FIG. 7 shows a possible path followed by the sock on the support.
  • a sock provides differently knitted zones and precisely: a foot 1 a , a heel 1 b , the leg 1 c and a leg collar id.
  • Such zones have different functions and precisely the foot 1 a is thickly knitted, heel 1 b is thickly knitted and curved, the leg 1 c has a tubular knitting, often with pattern, and the leg collar Id is a tubular collar knitted with elastic thread.
  • Such zones have been shown with different graphical background.
  • a knee sock 2 or tubular sock, instead, as shown in FIG. 2, has a tubular knitting with at the end a closure seam 2 a .
  • the foot is not knitted but is shaped when steaming the knee sock on forms.
  • elongated support 3 (FIG. 3).
  • the elongated support 3 notwithstanding shown of plain cylindrical shape, can have also grooves or oval or rectangular with rounded edges shape.
  • heel 1 b has a curved profile with a central vertex
  • the range 11 of the optical sensor 4 can detect this vertex calculating an average of the measured values, with possibility of sufficient precision for detecting the plane of orientation 9 (FIG. 6).
  • a plurality of sensors 4 or 5 can be provided, for example two, three or four angularly spaced sensors.
  • a control software is provided which, according to the sensor that detects heel 1 b or seam 2 a , a further rotation to the sock up to the orientated position.
  • an array of optical sensors can be provided, for example CCD or equivalent, which provides a matrix of signals of presence of the heel or of the seam.
  • the sensors detect the shape of the sock from the above.
  • they detect a line having a greater density, i.e. the seam.
  • mechanical sensors can be provided having tracing points capable of giving signals of presence when are touched by the heel or when they feel an higher thickness of the seam.
  • the rotation of the sock may be carried out by means of axial integral rotation of support 3 with sock 1 on a support base. Otherwise, as shown in FIG. 6, the rotation of the sock can be carried out by means of counter rotating movement of rollers 6 , 6 ′ tangential to the support that is kept still.
  • the elongated support 3 is as smooth as possible, whereas the rollers 6 , 6 ′ are coated by a friction surface, so that a relative movement of circumferentially tangential rotation is created between sock and support.
  • Support 3 can be a carrier in a production cycle. In fact, the sock must follow a path that comprises various work stations. In particular, with reference to FIG. 7, the following steps are carried out:
  • station 10 this is the step where sock 1 is put on support 3 ; more precisely, sock 1 is put on support 3 manually or automatically in a random way, being support 3 of shape preferably cylindrical elongated and vertical. Furthermore said support 3 follows the direction of a guide 8 .
  • station 20 a qualitative control of the sock is carried out; in particular support 3 with sock 1 , in addition to sliding along the direction of guide 8 , rotates axially about its own vertical axis for an angle of at least 180°. This rotation allows the operator 5 to check quickly the quality of the sock excluding preliminarily from the final packaging those socks having knitting defects, color defects and other.
  • the control can be carried out also by optical electronic instruments for defect recognition.
  • station 30 stops its movement of translation along guide 8 ; then the plane of orientation 9 of the sock (FIG. 6) is detected in the way above described. Then the support with the oriented sock goes on along guide 8 ;
  • station 40 sock 1 that is now in a predetermined plane, is withdrawn from support 3 for successive finishing steps, such as for example steaming and/or seaming.
