Abstract

A command device ( 1 ) for a knitting machine, the device comprising a body ( 2 ) of the device configured for movably housing at least an actuator, at least a command organ ( 5 ) movably mounted and associated to the body ( 2 ) and destined to interact with one or more organs of a knitting machine, for example one or more needles of the knitting machine, and/or with one or more threads infeeding into the knitting machine, and at least an actuator, movably housed at least partially in the body ( 2 ) and destined to controlledly move the command organ ( 5 ). The device ( 1 ) further comprises a support frame ( 10 ), associated to the body ( 2 ) and configured so as to increase the structural solidity of the body ( 2 ).

First claim

1 . A command device ( 1 ) for a knitting machine, the device comprising:

the device ( 1 ) comprising a support frame ( 10 ), associated to the body ( 2 ) and configured for increasing the structural solidity of the body ( 2 ).

2 . The device ( 1 ) of claim 1 , wherein the support frame ( 10 ) is configured for mounting the body, according to a determined mounting configuration, to a bearing structure ( 50 ) of the knitting machine, the determined mounting configuration of the knitting machine comprising at least a mounted position of the body ( 2 ) with respect to the bearing structure ( 50 ) of the knitting machine and/or wherein the determined mounting configuration defines a predetermined blocking force, guaranteed by the support frame ( 10 ) on the body ( 2 ) in the mounted configuration of the device to the bearing structure ( 50 ) of the knitting machine, and/or wherein the blocking force is such as to prevent a deformation of the body ( 2 ) during the mounting of the device ( 1 ) to the bearing structure ( 50 ) of the knitting machine, and/or wherein the body of the device is made in a single piece.

3 . The device ( 1 ) of claim 1 , wherein the body ( 2 ) of the device and the frame ( 10 ) are made of different materials, and/or wherein the body ( 2 ) is entirely made of a single material and the frame is entirely made of a single material, and/or wherein the body ( 2 ) is made of a plastic material, preferably a polymer material and/or a plastic material comprising a percentage of carbon preferably of at least 10% in weight and/or 20% in weight and/or 30% in weight, and the frame ( 10 ) is made of a metal material, preferably steel, iron, aluminium or alloys thereof.

4 . The device ( 1 ) of claim 1 , destined to be mounted to a fixed ring ( 51 ) of the bearing structure ( 50 ) of a circular knitting machine ( 51 ) developing circumferentially about the needle cylinder of the circular knitting machine, and/or wherein the frame ( 10 ) at least partially crosses the body ( 2 ) of the device, reaching, in the assembly configuration, the bearing structure ( 50 ) of the knitting machine, and/or wherein the body ( 2 ) of the device exhibits an upper surface ( 21 ) and a lower surface ( 22 ), the lower surface ( 22 ) of the body being destined to rest on a rest surface ( 52 ) of the fixed ring ( 51 ) of the bearing structure ( 50 ) of the knitting machine.

5 . The device ( 1 ) of claim 1 , wherein the body ( 2 ) comprises at least a first hole ( 31 ) passing through the upper surface ( 21 ) and the lower surface ( 22 ) and crossing an internal portion of the body ( 2 ), and the frame ( 10 ) comprises at least a first column ( 32 ), insertable in the first hole, and first fixing means ( 33 ) configured for joining the first column ( 32 ) to the body ( 2 ) and for mounting the assembly of the body-first column to the fixed ring ( 51 ) of the bearing structure ( 50 ) of the knitting machine, and/or wherein the first fixing means ( 33 ) realize one or more threaded couplings between the body ( 2 ) and the frame ( 10 ) and/or between the body-frame assembly and the bearing structure ( 50 ) of the knitting machine.

6 . The device ( 1 ) of claim 5 , wherein the first column ( 31 ) extends longitudinally between an upper end ( 34 ), positioned in proximity of the upper surface ( 21 ) of the body, and a lower end ( 35 ), opposite the upper end and positioned in proximity of the lower surface ( 22 ) of the body ( 2 ), and/or wherein the first fixing means ( 33 ) comprise a first thread ( 36 ), realized on the upper end ( 34 ) of the first column, and a second thread ( 37 ) realised on the lower end ( 35 ) of the first column ( 32 ), and/or wherein the first fixing means ( 33 ) comprise a first screw ( 38 ) and a second screw ( 39 ), the first screw ( 38 ) being configured for coupling with the first thread ( 36 ) and the second screw ( 39 ) being configured for coupling with the second thread ( 37 ).

7 . The device ( 1 ) of claim 1 , wherein the body ( 2 ) of the device is configured for positioning, on the fixed ring ( 51 ) of the bearing structure ( 50 ) of the knitting machine, in such a way that the first hole ( 31 ) collimates with a corresponding first vertical hole ( 55 ) passing through the fixed ring ( 51 ) of the bearing structure, and the lower end ( 35 ) of the first column ( 32 ), inserted in the first hole of the body, is positioned at the first vertical hole ( 55 ) of the fixed ring, and/or wherein the first screw ( 38 ) is vertically couplable from above to the first thread ( 36 ), so as to be superiorly solidly constrained to the first column ( 32 ), and the second screw ( 39 ) is configured so as to be vertically inserted, from below, during mounting, into the first hole ( 55 ) of the fixed ring ( 51 ), and so as to reach, by crossing the first hole of the fixed ring, the second thread ( 37 ) of the first column ( 32 ), the second screw ( 39 ) being inferiorly solidly constrained to the bearing structure of the knitting machine and the first column, and/or wherein the first screw ( 38 ) and the second screw ( 39 ) realize, respectively superiorly and inferiorly, a stacked assembly of the body ( 2 ) of the device to the fixed ring ( 51 ) of the bearing structure of the knitting machine, the body being fixed to the bearing structure, on opposite sides and in opposite blocking directions, by means of the first and second screw.

8 . The device ( 1 ) of claim 1 , wherein the body ( 2 ) of the device comprises a second hole ( 41 ) passing between the upper surface ( 21 ) and the lower surface ( 22 ) and crossing an internal portion of the body, and the frame ( 10 ) comprises a second column ( 42 ), insertable in the second hole, and second fixing means ( 43 ) configured for joining the second column to the body and for mounting the body-first column-second column assembly to the fixed ring of the bearing structure of the knitting machine, and/or wherein the second column ( 42 ) and/or the second hole ( 41 ) and/or the second fixing means ( 43 ) are substantially identical or equivalent to, i.e. exhibit the same characteristics as, respectively the first column ( 32 ) and/or the first hole ( 31 ) and/or the first fixing means ( 33 ).

9 . The device ( 1 ) of claim 8 , wherein the first hole ( 31 ) and the second hole ( 41 ) of the body ( 2 ) are distinct from one another and are separated by a distance of greater than 1 mm and/or greater than 5 mm and/or greater than 10 mm and/or greater than 20 mm, and/or wherein the first hole ( 31 ) and the second hole ( 41 ) have a respective longitudinal axis, the two longitudinal axes being preferably parallel to one another and lying on a vertical plane passing through a rotation axis of the cylinder and/or wherein the longitudinal axes of the first hole ( 31 ) and the second hole ( 41 ) are aligned along a radial direction with respect to the rotation axis of the needle cylinder, the first hole being closer to the rotation axis of the needle cylinder with respect to the second hole, and/or wherein the body comprises a third hole and the frame comprises a third column and third fixing means, the elements being substantially identical or equivalent to, i.e. exhibiting the same characteristics as, respectively the first or second ho
