Description

Machines for winding a fabric, such as gauze, are known in rolls, including a periodically checked drum with several kois which are solo mounted around it around the circumference and forcibly rotated bars for winding gauze and pressure rollers on them.

The described mask compared with the known automates the winding process and facilitates labor, for which it is equipped with a device for cutting and removing the coil and being rotated from an individual electric drive by a vertical camshaft, which carries on itself several vertical friction discs. The discs interact alternately with pulleys attached to rods for winding gauze, with a pulley attached to the axis of the rotary drum, and with a drive pulley on which the device for cutting and removing the coil is placed.

A device for cutting and removing a roll of gauze is made of an E. type of reversing lead screw interacting with a nut on which a disk is mounted to remove the roll and a holder with a knife blade.

FIG. 1 shows a front view of a car; in fig. 2 is a view of the mashina along arrow A in FIG. one.

The machine includes a vertical camshaft (rotated by an electric motor 2 through a gearbox 3. Four friction disks 4, 5, 6 and 7 are seated on the shaft, having the ability to move the shaft vertically for some distance and intended to turn on and off the working parts of the machine. These include a drum 8 periodically rotated by 90 °, mounted on axis 5, carrying two crosses Yu and P. In the cross Yu, bearings 12 are fixed, in which rods / 5 rotate, winding on gauze. The rods 13 are mounted in the crosspiece 10 console; other con # 126099-2 -

Rods are supported during winding gauze on them by folding spring-loaded brackets 14 mounted on a crosspiece, releasing the end of the rod during removal of the wound roll 15 from it. In the intervals between the bars, both crosses are connected by metal bonds.

Under the drum 8, a pair of spring-loaded pressure rollers 16 are mounted, moving in the vertical direction and pressing against the lower bar 13 during winding gauze on it.

Each of the rods 13 carries a pulley 17 at the end, which interacts with the friction disk 4 and rotates the bar, and on the axis 9 of the rotary drum 8 a cross-shaped pulley / iS is fixed, intended to periodically rotate the drum 90 °.

 The drum 8 mounted a device for cutting and removing from the rod 13 a roll deposited on it. This device is made in the form of a lead screw 19 of the receiving reverse rotation when the pzhiva 20 is mounted on its end and interacts with friction disks 6 or 7.

The screw interacts with the nut 21 fixed on the bracket 22 moving along the guides 23. On the bracket 22 the holder with a knife blade 24 ll of gauze cutting is fixed. On the nut 2 / the disk 25 is fixed to remove the roll from the bar. The device for removing the roll from the rod can be made in the form of two parallel disks 25 with blades mounted on the nut 21 and compressing the roll from both tors when removing it from the rod.

Work in the field is done in the following order.

The end of the gauze is placed on the front pressure roller 16, the electric motor 2, which drives the vertical shaft 1, rotates, and the handle 26 is turned. At the same time, the load ha 27 releases the tension of the springs under the rollers 16, and the latter are lifted up and pressed to the bottom screw 13. At the same time, the roller mounted on the handle 26, shuffled, and sliding along the bevel of the friction disk 4, lifts it until it touches the pulley 17 at the end of the lower bar 13. The drive starts to rotate, catching the end of the gauze with its clips and winds it to itself. After winding a certain amount of gauze, the bar is automatically turned off by a known mechanism. At the same time, the handle 26 moves back, the ha lowers the rollers 16, and the latches 28 lock the rollers in the lower position, making it possible to rotate the drum 5. At the same time, the handle presses the friction disk 5 s finger to the cross-shaped shchivka 18 on the axis of the drum 8. The finger rotates the drum 90 and out of engagement with the pulley 18, and the latches lock the drum in this position. The next bar 13 is in the lower position and is prepared for winding gauze. T ha 29, connecting the upper friction discs b and 7 with the lower disc 4, when lowering the latter lowers the discs 6 and 7. The disc 7, interacting with the tongue 20, rotates the spindle screw 19, which does not move the nut 21. The blade of the knife 24 cuts gauze, and the disks 25 remove the finished roll from the bar 13 when it takes the upper position. When approaching the end of the lead screw, the nut 21 presses the lever {not shown in the drawing), which raises the discs 6 to 7; the lead screw 19 begins to rotate in the opposite direction and the nut 21 returns to its original position. At the same time, the disk 4 is raised, which includes the next bar 13 for winding a roll of gauze on it.
