¹¹ rack arrangement for cargo knitting machines ¹ '»

The present invention relates to a rack and pinion arrangement for use in flat knitting machines, especially for flat knitting machines with two needle boards.

The purpose of the invention is to provide an extremely two-way Arrangement to procure a compact structure that is a practical Control of the various control members associated with the width of the fabric to be produced allows. Such Organs are well known in specialist circles; they include, among other things, devices for automatic weight gain and loss, arrangements for Limitation of the thread guide strokes, arrangements for regulating the ■ Tension in the scrapers, etc ...

The use of rack and pinion assemblies in knitting machines with two needle boards was previously considered drawn; However, these arrangements turned out to be very complicated, prone to failure and space-consuming.

The arrangement according to the invention overcomes these shortcomings -.- Basically, by removing them from the compilation two independently effective racks, which are on the rear the machine are arranged side by side; .with means, whereby either one or the other rack step by step can be moved to one side of the machine; with

Means whereby: the mentioned racks "both together moved gradually to the other side of the machine can be, and with means which are actuated by the movement of the racks mentioned and which the drive or to adjust the machine parts known per se.

Due to their very limited space requirements and their Compact structure, such an arrangement can be arranged on the rear of the machine without difficulty, without the width of the machine is exceeded. It is namely an additional feature of the inventive arrangement, that the two racks are each almost half as long like the thread beds used in the machine.

Other features and gate parts of the arrangement according to the invention will become clearer from the description below occur, which refers to the Ausftthrungsbeispiel illustrated in the accompanying drawings; show it:

Figure 1 is a sketchy representation of the inventive arrangement in perspective;

Figure 2 is a schematic representation of this arrangement, viewed in the direction of arrow F2 in Figure 1; Figure 5 shows a view according to arrow F3 in Figure 2;

Figure 4 shows a cross section along the line IV-IV in Figure 3 »

The arrangement according to the invention consists of two racks 1 and 2, each arranged on an endless chain 3 and 4, respectively are »On the one hand, these chains run over tensioning wheels 5 and 6, which are each attached to a shaft 7 or 8, and other

on the other hand on sprockets 9 and 10 , which are arranged on the rotating shafts 11 and 12, respectively.

The invention provides three racks 1 and 2 various possibilities of movement:.

1 ° - gradual advance of the rack 1 eu & closing-

, lent / the one honor (namely to the left in figure 3); this feed depends, for example, with the decrease on the front plate of the machine together}

2 ° - step-by-step sliding gate of rack 2 outside in one of the eights (according to linfcs in Figure 3)? this "feed depends, for example, with the decrease on the machine rear needle board together;

30 _ simultaneous gradual shifting of the two Racks 1 and 2 in the opposite direction (after on the right in Figure 3), for example for increasing on the both bathing boards »

The individual cream sticks are fed step-by-step in a single direction by means of two separate but completely identical organs I3 and I3 ♦; a single one of these organs will be described in greater detail below. The apparatus 13 for shift to the left of the rack 1 consists of a SperxJtlinke 14 s to a pin 15 is rotatable _f said pin of the pyramidal Köokens I7 can be moved laterally under the action of the inclined side sixteenth

The curl IT sits at the end of a vertical rod 16, which by a crouch 10 on the drive shaft 20 of the engine Lifted and alternately via a transmission gear is lowered; this gear consists of a

circumferential pole roller 22, an associated tie rod 25, a toggle lever 24 which is pivotable about a pivot 25, and an articulated connection between this Lever and the lower end of the lifting rod 18. By the action of an acting on the lower arm of the toggle lever 24 Tension spring 26, the pole roller 22 is printed onto the circumference of the cam 19 and at the same time the squat 1? prestressed, so that he is kept in the highest possible position will.

The arrangement for gradually moving the two racks to the right is shown in Figure 3 from a single pawl 27, which can be rotated about an axis 28 and under the action of the other inclined side 29 of the aforementioned cam 17 can be moved laterally. The width of this pawl is so large that the pawl can attack both racks at the same time.

By turning around their joint axes, the pawls 13, 13 »and 27 each individually either in an ineffective Rest position held, "or in an effective working position they are moved into the corresponding racks can intervene; this rotation of the pawls is done by means of individual, but mutually identical control rods, which are actuated by the central program control arrangement of the machine will. These control linkages consist mainly of a toggle or rocker lever 30, pivotable about an axis 31, the end 32 of one of the two lever arms being a stop or support point, whereupon the corresponding pawl rests, while the end 33 of the other lever arm on the one hand

by means of a pull cable 34 with the program control device the machine, and on the other hand via a tension spring 35 with is connected to a fixed point of the machine,

. By changing the pitch of the racks 1 and. 2 dem Unit dimension of the machine takes the same, the inclination of the inclined surfaces 16 and 29 of the cam should be determined so that the pawls are each lost by a distance that is slightly larger than this basic dimension "

In certain cases this route can be repeated twice the basic dimension. ·

As "already mentioned-the so-shaped tooth bar assembly can control several machine parts or * drive. For this purpose, the shafts 11 and 12 each with a plurality of gears 36, 37, 38 and 39 provided ₉ to be met by successively, for example, the following functions? regulation of Abstreifspannung, moving the stops for the thread guide, moving the waste and Zunehmglieder _s etc * _ÖE the skilled person will not be difficult to adapt the arrangement described herein in various applications, the respective existing practical requirements "

Any suitable arrangements, such as manually operated levers, which can act on the shafts 7 and 8, or fully automatic Gears can be used to reset the racks.
