Abstract
Description
- This invention concerns circular machines for knitwear and hosiery and refers especially to a device for raising a knitted item after it has been made, when it is taken from the needles and transferred by handling it out of the machine, for example to be able to effect the toe closing operation in the case of socks.
- Some circular machines for knitwear and hosiery employed for making knitted items to be taken and transferred out of the machine for successive complementary operations are equipped inside with a cylinder and a tube with summit flaring to receive the item as it being made by the needles. The tube can move vertically inside the cylinder to raise the item once finished, according to need, so that it can be taken close to the needles, taken off and removed above the cylinder with a suitable and anyway known of handling device. The flaring of the lifting pipe extends partially above the internal guide crown of the sinkers but cannot come close to the needles so as not to interfere with the sinkers when these are moving radially. In other words, the flared part of the pipe always remains at a distance from the needles and the closest part of the knitted item does not find any support on the pipe flaring. In this condition, when the tube is raised up it cannot completely and reliably raise the item so that it can be correctly and securely taken by the transfer device.
- The purpose of this invention is therefore that of supplying a circular machine for knitwear and hosiery in which the operation of lifting the knitted item always takes place correctly and securely.
- Another purpose of the invention is of offering a circular machine in which the knitted item is lifted from the knitting formation plane also by its parts closest to the needles for reliable picking.
- These purposes are achieved in a circular machine with a lifting device for the knitted item which includes a lifting pipe located in the cylinder, rotating together with this, adjustable in height and fitted with a summit bell with a flared lip which extends above the internal small sinker crown, as far as the circumference of the needles and which is provided with radial slits corresponding to the sinkers.
- Such a system permits the knitted item to rest on the flaring of the bell, whilst is it is knitted and to be raised on completion also in its part closest to the needles. On the other hand, the radial slits of the bell's flared lip permit correct sinker movement, avoiding interference with the same.
- Further details of the invention are more evident following a description made with reference to the enclosed, indicative but not limiting drawings, in which:
- FIG. 1 shows the section of the summit portion of a circular machine cylinder for knitting according to the invention; and
- FIG. 2 shows an aerial view of the knitting lifting device.
- In the said drawings of a circular machine for knitwear of the type considered, a
cylinder 10, withneedles 11 andsinkers 12 located radially around the summit of the cylinder are represented, supported by anexternal crown 13 and aninternal crown 13 guiding their radial-horizontal movements. - According to the invention, inside the
cylinder 11 and coaxial to the same there is apipe 15 which can be moved in height between a lowered position and a raised one, ending at the top with abell 16, Thebell 16 and thepipe 15, rotate together with theinternal sinker crown 14 to which they are constrained by at least one rotation drive pin. Thispin 17 engages in a correspondingvertical slit 18 which permits the height movements of thebell 16 - When the
pipe 15 is raised and lowered through an appropriate control device, not worthy of particular attention here. - The bell has an upper
flared lip 19 which extends above the small internal crown of the sinkers close toneedles 11 on the cylinder. The flared lip hasradial slits 20 around the periphery corresponding to the sinkers—FIG. 2—so as to permit the radial movements of these without interference. - The
pipe 15 with thebell 16 which can move in height and rotate can be placed outside aninternal pipe 21 which has a summit flare that coincides with theflared lip 19 of the bell when this is in the lowered position. Theinternal pipe 21 can be rotating or non-rotating, is fixed in height and is destined to receive the knitted item as it is gradually constructed. - In practice, as the knitting progresses it rests on the
flared lip 19 of the bell I6 and passes into the internal pipe without impediment. Once the item is completed theexternal pipe 15 is lifted up, with a consequent upwards movement of the bell and which also raises the knitted item including its parts closest to the needles, permitting its secure grasp for the picking and following handling.
