Description

one

The invention relates to knitwear production and is intended for dispensing round knitted knitwear products.

The known machine for the dissolution of the Vier-5 with a multi-system circular machine, containing a base, a crown fixed on it to don the stall, winding drums, spindles, thread guides, a device for turning off the spindles and the drive l3. On the axles of the spindles, levers are fixed with tgami, at the ends of which electromagnets are mounted. Devices for disconnecting the spindles 15 are microswitches electrically connected with electromagnets. In such a machine, when the thread reaches considerable tension, the winding mechanism stops by disconnecting the winding drum with the spindle from the common drive, after which for some time rotation of the winding mechanism by inertia with the same speed, and since the tension of the thread is sufficiently large, its breaking occurs.

In addition, the winding speed of the thread on this machine remains constant regardless of the length of the thread

In connection with this, the forces in the filaments causing the rotation of the crown are unevenly distributed. Occurs overlapping threads, entangling them and breakage.

The purpose of the invention is to reduce the breakage of the threads of the knit fabric that is being dispensed.

This is achieved by the fact that each winding mechanism is provided with an individual drive and has a means for controlling the winding speed, which is made in the form of rheostat sensors electrically connected with the winding mechanism drive. A DC motor is used as the winding mechanism drive.

FIG. 1 shows a general view of a knit dispenser; in fig. 2 - rheostat sensor.

The knitting machine consists of a base 1 on which a crown is installed for putting on the product, consisting of rods 2, arranged to move in grooves between the lower disks 3 and the upper disks 4.

The crown is freely mounted on axis 5, on which ring 6 with thread guides 7 to each winding mechanism is located. The winding mechanism consists of a motley drum 8, fixed on the base 1 by means of brackets 9 and provided with an axis 10, at one end of which the pulley 11 is located, via a belt drive 12 communicating with the direct current electric motor 13 and allowing for a wide range of smoothly controlled speeds.

The number of electric motors corresponds to the number of winding mechanisms. A spindle 14 is mounted on the winding drums 8, which by means of pivotally connected levers 15 and 16 are attached to the brackets e. On the base 1, thread guides 17 and 18 and rheostat sensors 19, through which rotation speed is controlled, are placed between the winding mechanisms. The rheostat sensor is a housing 20 in which a core 21 is mounted with a metal conductor 22 wound on it in a spiral. and one end connected to the thread, and the other to the metal conductor 22. The thread guide 18 is electrically connected to the electric motors and stops them in the event of a thread break.

The device works as follows.

On the rods 2 crowns place three KOTcWCHOe cloth, obtained from a multi-system circular machine. Each thread of a looped row, driven by a cgikda from the systems, is threaded through thread guides 7, 17 and 18, as well as through the sensor slider 24 and the winding drum 8 and fixed on the cone onto the spindle 14. When electric motors 13 are turned on through a belt drive 12, the drive t in rotation "etalny mechanisms. The thread is wound around a cone. Iodine, by the action of the thread being wound, turns the crown around axis 5. Depending on the type of interlacing of the knitted fabric, the threads from which it is formed have different lengths and, therefore, when they dissolve different tension; shorter threads experience greater tension. Passing through slider 24, they cause it to deflect and move along guide 23 along metal conductor 22. The higher the tension of the filament, the more the slider moves. The resistance of the electrical circuit linking the resistive sensor and the DC electric motor 13 increases, which leads to a decrease in the number of revolutions of the electric motor, and when the thread tension is strong, caused by its pulling, stop. With i

This winding mechanisms, dissolving threads, carried out by other systems, continue to work each

Q speed depending on the tension of its thread. When the thread tension is weakened, the slider 24 begins to move in the opposite direction, causing a decrease in resistance in the circuit and an increase in the rotational speed of the electric motor 13. In the event of a break in one of the threads, the yarn feeder operates - stop 18, stopping the entire device.

The use of the proposed knitting device

0 products allows to obtain smooth control of the speed of rotation of the winding mechanisms, depending on the tension of the threads. The result of this adjustment is to reduce

5 inertia of the winding mechanisms and, consequently, a decrease in the number of threads of the thread when wound.

Due to the fact that the thread having less tension, would be wound Q faster, and the thread with more tension slower, the forces between the threads that rotate the crown are evenly distributed, and this makes it possible to evenly unfold the product. The uniform feeding of threads to the winding mechanism improves the quality of winding and facilitates the further use of reels during their recycling. The proposed device makes it possible to eliminate tangling of threads on

0 the area between the crown and the winding mechanism, which takes place in known devices and often leads to increased breakage.
