Description

The invention relates to a knit machine industry, namely to the mechanisms for the selection of needles of flat-to-wall machines.

The purpose of the invention is to increase reliability in operation.

On flash, 1 shows the selection mechanism Hi l pposkos zachyyuy machine; figure 2 - node I in figure 1; on fig.Z - section aa in figure 1; Fig. 4 illustrates the structure of the embedding wedge.

The selection mechanism of the SHL contains a frame 1 with straps 2 and 3. On the clamp 3, there is a needle bed 4 with needles 5 and podgolnymi pushers 6 (figure 1). In the needle bar 4, an axis 7 is located, on which two shoulders levers 8 are installed. One end of the lever contacts the pusher t, and the second is pivotally connected to the selector pusher 9. In the working position, the pushers 6 are held by means of springs 10 hooked to the bracket 1 1. Initial The position of the pushers 6 is adjusted by means of the limiting angle 12. On the stitch 2, a housing 13 is installed, in the groove 14 of which the selector pushers 9 with heights 15 are located by the number of needles (Figures 1 and 2). Each pusher 9 has one pc 15, located in a certain way relative to the selector plate 16 mounted on the axis 17 in the inner part of the housing. The axis 17 supports the grid plate 16 in a predetermined position. The plate has a groove (Fig. 3), allowing it to move in the direction of the arrow and in the opposite direction. Along its length, the housing 13 erne contains one system of grooves 18, peremesonic grooves 14, in which webs of 19 selector plates 16. As can be seen from Figures 2 and 3, the grooves 14 and 18 intersect at an angle of 90V. To return the selector plates to the needle (L

the spring position serves as a spring 20 (fig.Z). The mechanism also includes a means of synchronizing the movement of the locking carriage with the wedges and the selector plates (not shown).

The L-area of the sunken wedge (Fig. 4) is calculated so that the selector pusher is held in its inactive position until the heel of the selector plate closes the groove for the heel to pass.

The mechanism works as follows.

Selection is carried out sequentially by one needle as the carriage progresses. With a wedge that acts on the heel, the pusher 6 retracts, through the double-arm lever 8, the movement is transmitted to the pusher 9, and the needle goes into the working area. Further, if the program contains information on the shutdown and operation of this needle, then the selector plate 16 goes into working position and locks with a finger 19, a groove 14 for passing the heel 15 of the selector pusher 9. After releasing the heel of the paddle pusher 6 from under the action of This pusher is turned off from work and is not involved in the process. If the selector plate 16 does not reach the working area, the plunger returns to the initial position under the action of a spring 10 D. The earlier fixed pusher is put into operation as follows. The selector plate 16 is released from the control elec

coping, after which the spring 20 returns the plate to its original position, thereby freeing the groove 14 for the passage of the pusher 9.

The proposed mechanism allows to increase the reliability in the hall equipment. The design of the mechanism has been solved in such a way that it can be used on all types and classes of machines with or without electronic control systems.
