Description

DETAILED DESCRIPTION OF THE INVENTION A method and apparatus for knitting pieces of a predetermined shape on an electronically controlled flat knitting machine by filling them with scrapable knitted pieces of material B) .

In order to form knitted pieces of a predetermined shape on a weight-controlled flat knitting machine, it is necessary to use a device equipped with a means for automatically retracting the knitted product from the knitting machine, or to continuously adjust the knitting width of the knitted piece. Doesn't it change the tension of all the stitches in each row? Devices that are made to be as uniform and regular as possible are often used. However, the equipment for withdrawing such knitted products from aircraft A is complicated and expensive.

In order to simplify such a device, it is known to fill the spaces between the knitted pieces of a predetermined shape with disposable uniform knitted pieces of lower grade material. However, in this case, a complicated operating procedure is required.

The invention, in a method and device of the type described above, considerably simplifies the operating procedure for emptying spaces between knitted pieces of a predetermined shape, so that the structure of the flat knitting machine is not unnecessarily complicated. The purpose is to do so.

To this end, the method according to the invention comprises knitting a predetermined shape, controlling a left-hand IJ limiter of a thread guide guiding the material of the piece in conjunction with a right-hand limiter of the thread guide guiding the material of the disposable knitting part. adjustable, and controls the right-hand limiter of the thread guide for guiding the material of the knitted piece of predetermined shape in relation to the left-hand limiter of the thread guide for guiding the material of the disposable knitted part; It is characterized by enabling.

It should be noted that if the knitted piece of predetermined shape is of symmetrical shape, the method according to the invention is advantageous in that the limiters of the thread guides are all controlled and adjustable in relation to each other.

Furthermore, in order to carry out the above method, the apparatus of the present invention includes a left-hand limiter of a yarn guide for guiding the matching of knitted pieces having a predetermined shape.
One liter is tied to the right limiter of the thread guide that guides the material of the disposable knitting piece through the connecting means, and the right limiter of the thread guide that guides the material of the knitting piece of a predetermined shape is connected to the second one.
The left IJ mitter of the thread guide guiding the material of the disposable knitted piece is connected via a connecting means, said first and second connecting means being longitudinally displaceable by individually controlled positioning means. It is characterized by what it did.

The positioning unit is preferably an electric motor or a stepping motor.

Note that when the knitted piece of a predetermined shape is symmetrical, the first connecting means, for example, a rod, is connected to the second connecting means, for example, by a reversing gear means.
For example, the two rods may be connected to a rod and the longitudinal displacement of the two rods may be effected by a single positioning unit.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In FIG. 1, a symmetrical knitted piece j, 2 of a predetermined shape is shown.

3 are shown arranged side by side with each other. These knitted sections can be sleeve-shaped, for example. 1 piece of organization],
The space between 2 and 3 is the discarded knitting piece 4.

Fill in 5, 6.7. In order to knit a knitted piece of a predetermined shape] to
Supplied by 10. In order to knit the waste knitting pieces 4 to 7, lower grade and cheaper materials are fed by the thread guides ]] to ]4. It is assumed that the discarded knitted pieces 4 to 7 are discarded after being separated from the knitted pieces 1 to 3 having a predetermined shape.

The cooperative relationship of the individual IJ mitters of the thread guide is shown in Figure 2. In order to make the control and adjustment system for the thread guide limiter as uncomplicated as possible and so that the operating sequence occurs straight ahead, the thread guiding the material of the knitted sections 1 to 3 of a predetermined shape is The left-hand limiters 15, 17[deg.] of the guides 8-]0 are connected by means of rods 29 to the right-hand limiters 22, 24, 26 of the thread guides []-]8, which guide the entire material of the waste knitted pieces 4-6. Further, the right limiter 16 of the thread guides 3 to 10 that guide the material of the m-acid piece] to 3 having a predetermined shape. ]8.20 is connected by a rod 30 to the left-hand limiter 28, 25.27 of the thread guide 12~]4 which guides the material of the waste knitted pieces 5-7.

Symmetrical pieces of a predetermined shape]~8, For example, when knitting a sleeve-like piece as shown in FIG. 1, two rods 29, 3
1+ is moved by ] controlled positioning units 3]. The kneading positioning unit (3) is connected to the rod 29 so that the movement of the shaft 29 is transmitted to the rod 30 by means of a reversing gear means (1) (not necessarily shown).

When knitting an asymmetrical piece of a predetermined shape, the rod 30 is connected to and controlled by its own positioning unit 32f. In this case, it is necessary to control the two positioning units 31 and 32 independently of each other.

The positioning unit 31, 82 is preferably a mold motor or a stepping motor.

[Brief explanation of the drawing]

FIG. 1 shows eight pieces of a predetermined shape to be knitted according to the invention, with the space between them filled with waste knitting pieces; FIG. 2 shows the common control and control of the thread guide limiter according to the invention; It is a route map showing an adjustment system. 1-8...
