Abstract

Device for controlling the thread guides of a single-cylinder circular knitting machine, which contains in each knitting system a control drum with an axis parallel to the axis of the needle cylinder, on the cylindrical surface of which there are also program elements for controlling the thread guides, on which the sensing levers rest. The space-saving control of the guides is solved in such a way that the program elements for controlling the thread guides rest on radially movable sensing levers, on the ends of which vertical arms rest on which the thread guides are provided.

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for controlling the yarn guides of a single-cylinder circular knitting machine, which comprises in each knitting system an actuating drum with an axis parallel to the axis of the needle cylinder.

A hosiery circular knitting machine is known in which the programming pins of the control drum are sensed by tangentially arranged levers against which the vertical bars engage the thread guides.

This arrangement has the disadvantage that the bars are arranged side by side and need to be guided respectively. This means that a certain needle cylinder is built up and the locks are not accessible, making their operation and adjustment difficult.

This disadvantage is solved by the arrangement of the program pins on the front of the actuating drum, where the actuating rods that abut the front do not cover the arc of the needle cylinder. This arrangement is suitable for machines with fewer thread guides in the knitting system, since multiple rows of pins cannot be placed on the front of the control drum with respect to the diameter of the drum.

Or the drum must be of a large diameter, which in turn is not suitable for machines that also control the pattern from the drum, for which it is necessary to reduce the diameter of the drum.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome these disadvantages in that the program pins for operating the thread guides are supported radially movably by the picking levers, the ends of which are supported by the vertical arms with which the thread guides are provided.

1 shows a side view of the arrangement of the picking levers and wires, FIG. 2 shows a top view of the arrangement of the control drum, the pickup levers and the thread guides, FIG. 3 shows the same as FIG. 1, but the sensing levers are mounted in a different axis, FIG. 4 shows a top view of the bearing according to FIG. 3 with the representation of the control drum.

The known one-round circular knitting machine for the production of hosiery or the like is provided in each knitting system with a control drum 6 (FIG. 1). 2), the axis of rotation of which is parallel to the axis of the needle cylinder (not shown).

On the cylindrical surface of the control drum 6 are program pins 6 for controlling the thread guides and other program elements (not shown) for operating the locks. The program levers 6 are supported by sensing levers 54, which are arranged radially pivotable one above the other on the pin 8, as shown in FIG. 1.

The pin 8 is fixedly mounted in the machine frame 6. The sensing levers £ - £ are successively starting from the upper sensing lever £ to the lower sensing lever £ of gradually increasing lengths, at these ends with adjustment screws 31-71.

The adjusting screws 31-71 are supported by the vertical arms of the thread guides 10-14, which are pivotably mounted on a pin 15 arranged in the frame of the machine. The operation of the device described above is as follows.

When the actuating drum 8 is pushed, the program pins 8 act on the shifting levers £ - £ and swing them between the dashed position and the fully indicated position of FIG. 2. If the programming pin 8, for example, swivels the sensing lever £, 10 and is lifted from the working to the non-working position.

Upon removal of the pickup lever 6 from the pin 6, the conductor 10 is brought into a non-working position. The adjusting screw 31 then serves to precisely limit the oscillation of the conductor 8, which may be different for each conductor, e.g. the working position of the amplifying conductor is higher.

The other conductors 4-T_ operate similarly. Within the scope of the invention it is possible to accommodate the sensing levers of the actuating drum 1 in other ways, for example according to the arrangement in Figs. 3 and 4, wherein the sensing levers 3 '- 7' are provided with arms 32 '- 72' which are pivotably mounted on the pin 8 '. in frame £.

The other arrangement is the same as the previous one. Thus, the pick-up levers 3 '- 8 swing in the same sense as the yarn guides 10-14 as seen from the dashed position in Fig. 4.
