Definitions

  • the present invention relates to a method and a device for the automatic positioning of the stockings in a machine for forming tights, with the automatic detection of the garter line.
  • two stockings must first be threaded, individually, on a pair of flat shapes, paired, superimposed and, then, aligned vertically and juxtaposed, so as to obtain the correspondence of the elastic edges of the body of the two stockings and the corresponding garter lines, which determine the dividing line between two areas of the stockings with fabric of different density, as is the case for the body and leg of each stocking.
  • the two stockings thus positioned must be cut longitudinally, from the elastic edge of the body to a predetermined distance from the garter line.
  • the technical solutions known to date, for placing the two stockings to be united in a predetermined position to form a pantyhose arise, essentially, from the same origin.
  • the two stockings are threaded, randomly, on the respective support forms; then, optical sensors, movable in the longitudinal direction of the shapes, detect the position of the elastic edges of the bodies to control - with a horizontal translation towards the end of the shapes which is opposite the tip - the activation of first clamping means for picking up said edges to drive them to a predetermined position of reciprocal vertical alignment; successively, by means of second clamp or track means which act on the lateral portion of the stockings threaded on the forms and are controlled by second optical sensors, translate the stockings towards the point of the forms, until depositing in an extended position the portion of each stocking comprised between the elastic edge of the body and the garter line and until the vertical alignment of the two garter lines is obtained.
  • the main object of the present invention is to provide a method and a device for positioning two stockings intended to be united to form a pantyhose, which makes it possible to obtain a significant reduction in the cost of manufacturing machines for pantyhose, as well as time required to position the stockings, while at the same time guaranteeing high operating reliability.
  • the advantages obtained thanks to the present invention essentially consist in the fact that it is possible to carry out the correct alignment of the garter lines of the two stockings to be joined to form the tights, in a simple, rapid and precise manner; in that a device according to the invention is simple, economical and reliable to manufacture even after a long period of operation.
  • FIG. 1A schematically represents a side view of a device according to the invention, in the rest position;
  • Fig. 1B shows the device of FIG. 1A in the advancement phase with opening of the clamp to grab a stocking;
  • Fig. 1C shows the device of FIG. 1A in the gripping phase of a lateral portion of the bottom;
  • Fig. 1D represents the device of FIG. 1A in the retraction phase with stretching from the bottom;
  • Fig. 1E shows the device of FIG.
  • FIG. 2A shows a plan view of the device of FIG. 1A
  • Fig. 2B shows a plan view of the device of FIG. 1B
  • Fig. 2C shows a plan view of the device of FIG. 1 C
  • Fig. 2D represents a plan view of the device of FIG. 1D
  • Fig. 2E shows a plan view of the device of FIG. 1E
  • Fig. 3 schematically represents the plan view of a device according to the invention, according to an alternative form of implementation.
  • said clamp means (1) are slaved to an alternative translation in the oblique direction (F1) relative to the longitudinal axis (8) of the corresponding shape (5).
  • said clamp (1) is of the type with normally closed flat jaws (15).
  • a stop element (6) is interposed between the head of the clamp (1) and the corresponding control cylinder (2), so as to limit the operational return stroke of the clamp (1) and exert a push on the back of each jaw (15) and generate a moment of opening of the clamp (1) and release of the bottom (4).
  • an elastic blade (10) is mounted astride, longitudinally, on the two jaws (15) of said clamp (1) so as to allow its spontaneous closing in the rest position.
  • said cam (3) has a double rectilinear profile with symmetrically divergent development towards the form (5) of bottom support (4) for controlling activation, that is to say the opening and respectively closing of said clamp (1), in cooperation with two axes (11), each of which is housed idly in a corresponding jaw (15) of the clamp (1), so as to be laterally projecting from it and thus cooperating with a corresponding profile of the cam (3) during the movement of the clamp (1): said cam (3) being interposed between the cylinder (2) for movement of the clamp (1) and the shape (5) of bottom support (4).
