Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a modular needle selection device, in particular for use in a main knitting element of a knitting machine. The invention also operates on some of the knitting elements arranged in each groove of the knitting head of the knitting machine, as described below.

The device of the invention is designed such that each of the needle selection devices is autonomous, regardless of the total number and location of the needle selection devices. That is, each can move the main knitting element to form stitches without the aid of other needle selection devices. By using this new device in a knitting machine, apart from the compatibility between modular needle selectors, a knitting machine with an infinitely large number of actuators can be obtained. In this case, the only limitation on the number of actuators is where they are installed.

The needle selection device is equipped with all the cams necessary for knitting or stitch transfer, thereby making it possible to simultaneously obtain three types of knitting operations. That is, it is possible to set the knitting/mesh knitting/non-operating position without prior preparation by other needle selection devices.

The device of the invention also performs two transfers, namely -
With this needle selection device, it is also possible to simultaneously perform stitch passing and stitch receiving from the front side to the back side or vice versa.

Another feature of the invention is that the cam, which was movable in previously known devices, is now fixed.

This greatly reduces the number of failures and makes maintenance easier.

On the other hand, the needle selection device of the present invention, due to its independence in that each can independently move the main knitting elements forming a stitch, allows the first needle selection device to prepare the operation to be completed by the second needle selection device. Compared to previously known devices with needle selection devices, it is possible to obtain a knitting machine with a significantly larger number of needle selection devices.

The device of the present invention is disclosed in Patent No. 405, owned by the applicant.
It is based on the use of electromagnets as used in the invention of No. 001.

Another feature of the invention is that one primary key, particularly made to move in a spring-like manner, is articulated to each knitting needle, and even though the primary key is only equipped with a - butt, four It is possible to perform three operations: knitting, mesh knitting, stitch receiving, and stitch passing. On the other hand, in a conventionally known device, the main key is provided with two six-butts, and an auxiliary key with a butt is present between the key and the key. The sole purpose of this bat is to provide auxiliary key return with a corresponding alignment cam, similar to the main key bat.

In order for the foregoing description to be more complete and for a better understanding of the features of the invention, reference will now be made in detail to the accompanying drawings. In addition, in the illustrated embodiment, 4
Although sets of modular needle selection devices are shown, of course this number of sets is merely exemplary and may be greater or less than four as desired.

Each figure shows a side sectional view of the knitting head cut along the knitting elements of the knitting machine, a skeleton diagram of the needle selection device of the knitting machine, and batts B, C, TI, T2. Various paths followed by the TS are depicted. In the side sectional view of the knitting head, all knitting elements are illustrated. The knitting needle A is of a transfer type, and the primary key CP is articulated B to the knitting needle A, so that the two cooperate. This is advantageous when the knitting needle A and the main key C are required.

The primary key CP is actuated like a spring so that its only butt C moves to an activated position or a non-activated position. The inoperative position is as shown in Figure 3.
Through the cooperation of cam F and rose 1-Tl of auxiliary key CA,
This is the position where the bat C is sunk into the groove of the knitting head.

In the operating position, the hat C protrudes outside the groove of the knitting head, and the needle selection device J1. This is a position within the action area of the J2 cam. Thereby, it is possible to set it to any of the four operating positions described later. Auxiliary key CA bat T
2, like the butt B (operated by the alignment cam EB) formed by the combination of the knitting needle A and the main key CP, is mainly used for returning the auxiliary key CA to its original position by the alignment cam ET.

The knitting, the element knitting needle A, the primary key CP, and the auxiliary key CA have been described above.Next, the knitting element jack selector JS will be described.

Jack selector JS is the first. Second. As shown in FIG. 4, the magnetic core E of one of the electromagnets arranged on the knitting head pushes it toward its operating position. When the bat TS is selected, the first TS. Second
