DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an apparatus for loading a line closing machine.
In the hosiery industry, much of the production of panti-hose uses a line closing machine such as a Takatori Line Closer. Hitherto, such line closing machines are loaded manually with two stockings which are to be seamed into a pair of panti-hose.
The present invention seeks to provide an apparatus for loading a line closing machine with stockings to be seamed into a pair of panti-hose.
Accordingly, the present provides an apparatus for loading a line closing machine, the apparatus comprising a carousel unit having a plurality of transfer arm means, the carousel unit being rotatable to move said transfer arm means successively through a loading station and at least one transfer station; and wherein each said transfer arm means has support means for supporting a pair of stockings, said support means being movable between a first position enabling engagement of supporting means of said line closing machine with said stockings and a second position to allow said supporting means to disengage said stockings from said support means.
The present invention is further described hereinafter, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a plan view of two known line closing machines with a preferred embodiment of the present invention shown in outline;
FIG. 2 is a perspective view of a transfer arm of the apparatus of FIG. 1;
FIG. 3a is a side elevation of a pair of fingers of the arms of FIG. 2 in an extended position;
FIG. 3b is an end elevation of the fingers of FIG. 3a as seen in the direction of arrow A of FIG. 3a;
FIG. 3c is a plan view of the fingers of FIG. 3a;
FIGS. 4a, 4b and 4c are views similar to those of FIGS. 3a, 3b and 3c showing the pair of fingers in a retracted position;
FIG. 5 is a perspective view of the arm of FIG. 2 in a loading position;
FIG. 6 is a side elevation of the transfer arm prior to engagement with supporting arms of a line closing machine;
FIG. 7 is a view similar to that of FIG. 6 showing the supporting arms engaged in the stockings on the arm;
FIG. 8 is a plan view of the arrangement of FIG. 7;
FIGS. 9 and 10 are view similar to that of FIG. 7 showing subsequent operating positions of the supporting arms; and
FIG. 11 is a plan view of a portion of a cam track of the apparatus at a transfer station
Referring to the drawings, FIG. 1 shows two line closing machines 10, 12 with a preferred form of loading apparatus 14 according to the present invention positioned in alignment with and between the two line closing machines. Such line closing machines are well known and do not form part of this invention. Each line closing machine has six pairs of supporting arms 16 and the machines are arranged to rotate in the same direction (clockwise as seen in FIG. 1), 30 degrees out of phase, such that the pairs of supporting arms of the two machines alternately present themselves to the loading apparatus to enable transfer of pairs of stockings from transfer arms 18 of the loading apparatus to supporting arms of the line closing machines at transfer stations 20. To this end, the loading apparatus is provided with twelve equally angularly spaced transfer arms 18, a first set (six) of these (every alternate one) cooperating with one of the line closing machines and a second set (the other six) cooperating with the other line closing machine.
The loading apparatus 14 rotates in an anti-clockwise direction and as each alternate transfer arm 18 of those cooperating with the line closing machine 10 passes through a transfer station 20 the transfer arm is extended to enable transfer of the stockings. The extension of the transfer arms can be effected by suitable means such as fixed cams which act on a camming surface on each of the arms (described further below).
FIG. 2 shows a free end of a transfer arm of the loading apparatus, the arm having an elongate support member 22 which carries at its outer end a generally U-shaped bracket 24. The outer ends of the limbs of the U are joined
