Description

In cotton factories, after the carding machines, the yielded yarn is transferred to single-pair rolled rolls of periodic action. In connection with the lack of an automatic roll machine, the pelzo will carry out threading at the primary cotton processing site.

A new machine allows to transfer a cotton factory to continuous work on a separate section of its technology - primary cotton processing.

The tape-connecting machine for continuous winding of rolls is a rotary-type machine, containing two mutually arranged winding mechanisms, vras, with relative movement around the horizontal axis in the process of winding tapes into a roll. The application of the principle of combination of winding and portable movement of the winding device makes it possible to wind the roll for a short time, automatically turn on the next sleeve for winding the roll between the discs and place the sleeve in such a position that will provide automatic winding.

FIG. 1 shows a machine diagram; in fig. 2 - section but AA.

The belt-connecting machine consists of the following main parts: bed 1, central shaft 2 with gear 3 mounted on it, winding drums 4 rigidly mounted on shaft 5, gear 6, movable crackers 7, prulsiny 8, sleeves 9, disc 10; a roller 11 with tongs 12, a rail 13, a driving cone 14, a roll 15, a roller 16, side cheeks 17, an electric motor 18.

The machine works as follows. Canvas from carding machines comes along a belt conveyor 19. In position A, the canvas is initially filled onto a sleeve 9, filed for refueling by a belt conveyor, the movement of which is coordinated with the machine cycle. The next sleeve 9 is in position B and is fed under the axis of the disk 10 when the latter is pressed on the roller 11, while

No. 137429-2 one of its tabs 12 keeps the sleeve from falling. A winding device consisting of winding drums 4 rigidly mounted on the shaft 5 in bearings mounted in the side cheeks 17 rotates clockwise around a horizontal axis. The winding drums 4 are rotated from the gear 6, which is in the setting with gear 3. The canvas pressed between the winding drum 4 and the sleeve I is wound on the last, and the remaining end of it is rolled onto the roll 15. During the winding of the roll 15, the axis of the sleeve 9 is located in movable cracks x 7. The winding density is provided by adjusting prrussina 4, and in the lower position as a roll counterweight damper is the following: it is spring 2L In position-B, the process of winding roll 15 ends. Then, the wound roll moves further, and when the rail 20 of J3 is pulled out, the disks 10 automatically expand, the lead-in cone 14 leaves the sleeve 9 and the roll 15 falls along an inclined plane. The discs 10 in the extended state are moved with the help of the roller 16 to the upper position along the rail 13 rigidly fixed to the bed /. After reaching the upper vertical position, the disks 10 freely cross the line B of the canvas movement and, having reached the slope of the slide 20, under the pressure of the spring 22 converge, putting the new sleeve 9 on the receiving ends of the lead-in cone 14, leaving the line of the canvas behind. Then, under the influence of the spring 8, the sleeve 9 is drastically lowered from the disc 10 along the groove of the side cheeks 17.

Claims (3)

1. A tape connecting machine comprising two pairs of sliding spring-loaded discs for clamping empty reels, two pairs of rolling drums and a mechanism for cutting the canvas, which is designed to ensure the continuity of the operation of the maschine in the production line of the cotton spinning industry, it is made in the form of two vertical parallel frames, freely seated on a horizontal shaft, carrying a central gear wheel and continuously rotating relative to the shaft with frames fixed at diametrically opposite ends, are continuous visually rolling around the central gears of the rolling drums, provided with annular grooves and imparting movement to the spring-loaded, sliding disks, rolling pins, equipped with annular rows of needles, winding the tape on the tape, and for expanding and drawing together the disks, when ejecting the slats or clamping the machine, the machine rolls on the ribbon two curved guide rails, carrying on the ends of the slide, interacting with the discs. 2. The machine according to claim 1, characterized in that for fixing the spreading discs in a predetermined position, it is equipped with mechanisms, each of which is designed as a nut freely mounted on the extension axis of the sliding disk, forming a screw pair with an axle a disk with a screw, as well as gear teeth, alternately interacting with one of the two curvilinear gear rails fixedly mounted on the frame and located on the movement path of the sliding disks. 3. A machine according to claim 1, characterized in that the mechanism of the accumulated canvas is made in the form of two elastic rollers rotating towards each other mounted on one-shoulder arms: one rotated around a fixed point, and the other hinged on the rotating frame, carrying on the end of the curvilinear plate - the cutter.
