Description

The invention relates to the knitting industry and relates to a device for an individual needle drive, which can be used in various knitted machines.

Known is the individual needle drive of a knitting machine, including a source of movement and a device for selecting and controlling the movement of the needle, kinematically connected with the needle itself, in an amount corresponding to the number of needles (Pat. USSR No. 154634, IPC 7 D 04 B 15/36, 07/06/1963) .

The disadvantages of the known drive are the design complexity and limited technological capabilities.

An object of the invention is to simplify the design and expand technological capabilities.

The technical problem is achieved in that in an individual needle drive of a knitting machine, including a source of movement and a device for selecting and controlling the movement of the needle, kinematically connected with the needle itself, in an amount corresponding to the number of needles, according to the invention as a source of movement and a device for selecting and controlling the movement of the needle The design of the electromechanical converter, made in the form of spatially located modules of a reversing linear stepper motor, is used. The modules are connected to the outputs of the control computer information.

According to the invention, electromechanical transducers are located above and / or below the needle web in the form of tiers.

The modules of the electromechanical converter are located in a vertical plane, and the outputs of the modules are kinematically connected with the common output of the electromechanical converter.

To place electromechanical converters within the step determined by the machine class, they are placed above and / or below the needle sheet in the form of tiers or in the form of modules located in a vertical plane, while the outputs of the modules are kinematically connected with the general output of the electromechanical converter.

Figure 1 shows an individual needle drive with an electromechanical transducer located above the needle web. Figure 2 shows an individual needle drive with an electromechanical transducer located under the needle web. Figure 3 shows individual needle drives with electromechanical transducers placed in two tiers above the needle web. Figure 4 shows individual needle drives with electromechanical transducers placed above and below the needle web.

The individual drive (figure 1) consists of a reversible linear stepper motor located on the needle web 1, consisting of an inductor 5 and a gear rack 4, which is rigidly fixed. A command is received from the built-in control computer to the reversing linear stepper motor, and the inductor 5 moves, in accordance with the received command, and through the kinematic connection 3 introduces the needle 2 into the working area, where the thread is laid on it. The depth of curation is determined by the movement of the inductor 5, the amount of movement of which depends on the command received from the control computer. After the operation is completed, the needle is returned to the working area.

The individual drive (figure 2) works similarly to the drive shown in figure 1, only the gear rack 4 is connected, connected to the needle 2 through a kinematic connection 3, and the inductor 5 is rigidly fixed in the housing 6.

In the case when, within the limits of the step determined by the class of the machine, the electromechanical converters cannot be placed in one tier, they are placed in several tiers above and / or under the needle sheet (Figs. 3 and 4).

Figure 3 shows the individual needle drives with electromechanical converters placed in two tiers, the 1st tier on the needle web, the 2nd tier on the casing 7. The drive operates similarly to the drive shown in Fig. 1.

Figure 4 shows individual needle drives with electromechanical transducers placed above and below the needle sheet, the inductors of which 5 are rigidly fixed in the housings 6 and 7, and gear racks 4 are connected, connected with the needles through kinematic connections 3. The drive works similar to the drive shown in figure 1.

In order to change the stopping depth, the interface protocol provides for the possibility of supplying pulses to the inductor coils of a reversing linear stepper motor with step crushing.

The implementation of the selection and inclusion of needles in the work is carried out by forming the appropriate teams at the output of the control computer.

By replacing the source of movement and the device for selecting and controlling the movement of needles, consisting of drive shafts with cams, rotary levers, etc., by a reversible linear stepper motor, the design has been greatly simplified, and this replacement allows the drive to be used on various types of knitted machines, such as plane-flat, flat-knitting and others.
