Description

For the mechanization of rope twisting, machine tools equipped with clamps mounted on gears rotated by any engine and a moving carriage are known. In the proposed machine for facilitating work, the carriage movement direction change is performed automatically by means of levers located in its path tied with rocker arm articulated with a switching coupling.

In FIG. 1 depicts a general view of the machine; FIG. 2-view of the front of the machine; FIG. 3-side view, carriage with a partial cut; FIG. 4-view reversing mechanism.

When fusing wood, the rafts are tied up with ropes, and the use of hemp or urine ropes is very expensive due to the relatively high cost of the material and its short lifespan. Ropes twisted from wood rods-vits, which are very durable and convenient to use, are widely used to reduce the cost of floatation, but, however, manually making such a rope is a process that requires considerable labor and time.

Rope twisting machine from

The rods consist of a front part for spraying individual rods and a carriage for twisting rods into one rope. The fixed riveted design of the front part has on itself from the side of the working shield 1 with points 2, in which the worker lays the beams of the wits, going to the manufacture. the rope. The size of the point makes it possible to always have the same thickness for the rope. After passing through the glasses, the particles fall between the rollers 3 with a notch, which are free to sit on their axes and fixed in rotating discs-gear 4.

Usually the rope is woven from three strands and therefore three gears 4 and three points 2 are installed in the wall.

All gears are driven in rotation by the Middle Drive Gear 5 and supported from falling by two small parasitic gears 6 fixed to the frame, where they are adjusted to be able to adjust the entire system. When all gears are simultaneously rotated, the rods that fall between the rollers begin to twist and twist into the straps. The second worker takes all three ends of the twisted ribs and pulls them through.

to the clamp 9 of the carriage, standing in the extreme forward position.

When the carriage is activated, the spindle 7 begins to rotate and, unscrewing from the nut 8, tightens the clamps 9, which clamp the ends of the strands. The clamped ends, rotating with the spindle, are twisted into a rope. The carriage, which rotates from the common shaft 10 through the sprocket 11 and the chain Gall 12 with the servo 24, gradually moves back to the required length of the rope (6 m).

The rotation of the spindle is transmitted by means of a pinhole 13, rolling along the rack 14, the rotary axis 15 with bevel gears 16, 17.

After making a path equal to the required length of the rope, the carriage presses the lever 18, which, through 19, rotates the rocker 20 n lever 26, and switches the coupling 21 to the gear 22.

In this case, the common shaft begins to rotate in the opposite direction, and the carriage returns to the original polonsenie. At this time, the rope is removed. When the carriage reaches the extreme forward position, the carriage rests again on the lever 23, which, through th 25, switches the clutch 21 to the forward stroke, and the twisting process begins again.

The subject matter of the invention.

A machine for twisting ropes from rods with rotating clamps and a movable carriage, characterized in that for automatically changing the direction of movement of the carriage, pivoted-mounted levers 18 and 23 are used, located in the movement path of the carriage and connected by rods 19 and 25 with the beam 20, carrying shift clutch lever 26 21.
