Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a linking machine for knitted products, socks and socks.

More particularly, the present invention relates to a linking machine needle rod (necdlt: necdlt:bar) of the type disclosed in co-assigned Ecly patent application Ser. Nos. 757,021 and 804,750.
) and a control device for a yarn loop device (yarn Io'oper).

In such a linking machine, the above-mentioned patent application No. 757
According to the specification of No. 021, at the same time as the tiffl reciprocates in one direction, the needle rod partially rotates around its own axis so that the needle can insert thread and stop the stitches for chain knitting. make a rotational movement.

Furthermore, the needle is eccentrically fixed to the needle rod so that it can follow the movement of the tip, so that there is no conventional camming device to cause orthogonal movement of the needle.

Like other linking machines known in the art, this linking machine has the inconvenience of knitting only by rotating the ring in one direction, either clockwise or counterclockwise, depending on the type of construction.

In detail, in conventional linking machines, the movement of the needle rod and thread ring device must be controlled in order to change from knitting by rotating the knitting ring clockwise to knitting by rotating the knitting ring counterclockwise. It requires some changes to the equipment, and its operation is inherently complex and time consuming. Furthermore, in the linking machine disclosed in the above-mentioned patent application, the device for controlling the movement of the needle rod and thread ring device is complex and delicate.

The purpose of the present invention is to enable the conventional linking machine to operate even when the knitting ring rotates clockwise or counterclockwise without changing any part of the device, and to allow rotation in one direction. It is an object of the present invention to provide a device for controlling the movement of a needle rod and a thread ring device, which requires reversing the direction of rotation of a machine morph to change from rotation to the opposite direction.

Another object of the present invention is to provide a device for controlling the movement of a needle rod and thread ring device that is extremely simple to operate and assemble and is capable of high speed operation.

According to the invention, the movement of the thread ring device cooperating with the knitting needles of the needle rod and the knitting rod is driven by separate crank levers, each of the crank levers having a crank pin;
A linking machine for frequently used knitted products, socks, and stockinettes is provided, in which the axis of the crank pin is inclined with respect to the axis of rotation of the crank lever itself.

Because of the rank lever, the hem ring rotates in the opening direction and the thread ring device does not pass the knitting yarn through the hook of the knitting needle even if the hem ring rotates counterclockwise. Unlike the machine, the crank lever that controls the movement of the thread ring device ensures that the thread ring device always follows the same path around the wire side, whether the knitting ring turns clockwise or counterclockwise. This is possible by doing this.

The present invention will now be described in detail with reference to the drawings showing one embodiment.

In the figure, the needle rod 4 is coaxial with the knitting ring 1 of the linking machine.
A support arm 2 for the stitch forming device is provided, consisting of a line side 3 and a thread ring device 5, which are arranged eccentrically.

The rod 4 is movable around an axis and is provided so as to be able to rotate around its own axis within a housing 6 fixed to the arm 2. The end of the 91 rod 4 opposite the knitting needle 3 is connected to a universal joint 7, which is fixed to a yoke 8, and the yoke 8 is pivotally connected to a support block 10 via a pin 9. It can be attached freely. The lever 10 tightly tightens a pin 11 constituting the crank pin of a crank lever 12 driven by an axle 13. The axis of the pin 11 is inclined about 1 with respect to the axis of a shaft 13 connected to a shaft 15 controlling the rotation of the channel ring 1 via a pair of umbrella arms 14.
There is ζ.

Crank lever 12 &; Take it perpendicular to J 13.
The plate 1 has an extension 17 which is inclined with respect to the plane of rotation of the plate 16. Extension part 17
A pin 11 is vertically and rotatably attached to the pin 11, and the needle rod 4 is connected to the pin 11 via a block 10, a yoke 8, and a universal joint 7.

More specifically, the pin 11 is a saw that is coaxially fitted into a bush 11' fixed to the extension part 17.

The thread ring device 5 is attached to the arm 2 (=J), and a bar 19 is attached to the arm 2 so that it can move around the bushing 20 and rotate around its own axis. The arm 18 is fixed to the bar 19.
The end opposite to 1 and 18 is fixed to yoke 2], =
It is an I-ri which is pivotably attached to the block 23 via the 21-center connector 22. The block 23 has 31 on the shaft 26,
It is pivotably attached to the pin 24 that constitutes the crank pin of the crank lever 25 that is operated (=t tJ).

The axis of the pin 24 is inclined with respect to the axis of the shaft 2G. The crank lever 25 is composed of a cylinder 27 fixed coaxially to a shaft 26, and has a surface 2B cut by a surface inclined with respect to the longitudinal axis on the opposite side from the shaft 2G. A pin 24 is fixed perpendicularly to an inclined surface 28 near the edge of the cylinder 27 near the longest generatrix. To be more specific, the block 23 is fixed to the pin 24 by the collar 32 of the tightener.

A crank lever 12 that controls the movement of the needle rod 4 γ11
Now, because the pin 11 is inclined, the metal rod 4 makes two half-turns in the opposite direction around its own axis for each rotation of the crank lever 12.

The extent of half a rotation of the needle rod 4 is determined by the angle of inclination of the axis of the pin 11 with respect to the axis of rotation of the lever 120.

The half-turn of the needle rod 4 occurs when the needle rod reaches and passes the bottom dead center and immediately when the wire side 3 should pick up the knitting yarn and rotate to release it.

Crank lever 2 for controlling the movement of the thread ring device 5
5, the pin 24 or crank pin is tilted so that the bar 19 vibrates within the bushing 20 each time the crank pin lever itself rotates one degree.

The angle of inclination of the surface 28 of the cylinder 27 with respect to the long axis of the cylinder itself determines the degree of vibration of the bar 19 within the bushing 20.

This vibration, coupled with the unidirectional movement component of the crank lever 25, causes the thread ring g''l 15 to simultaneously undergo a rotational movement and a unidirectional movement around the knitting needle 3.

The adjustment shafts for crank levers 12 and 25 are shafts 13 and 2.
They are interconnected by a heald 29 which cooperates with a pair of pulleys 30 and 31 which are fixed to each other. The diameter of pulley 30 is larger than the diameter of pulley 31 so that the transmission ratio between shafts 13 and 26 is 1=2.

The crank levers 12 and 25 are adjusted in phase with respect to each other so that when the rod 4 reaches the top dead center, the thread ring device 5 just passes through the bottom dead center.

In this way, when the knitting needle reverses its movement in one direction, it rotates around the knitting needle with a short return. At the same time, the knitting needle rotates half a turn in the direction opposite to the concave curve of the thread ring device 5.
