SU27034A1 - Machine for mechanical unwinding of barbed wire and removing barbs from it - Google Patents

Description

The proposed machine has the purpose of mechanical unwinding of barbed wire and the removal of thorns from it.

In the attached drawing of FIG. 1 depicts the type of the proposed machine from the side; FIG. 2 - its top view; , figs. 3 is a longitudinal section of the mechanism for removing the spines.

On frame A (Figs. 1 and 2), an iron frame D is fastened with the help of racks B, which can rotate on horizontal trunnions and carries the transverse axis O on it to place a coil of wire on it. At the end of the trunnion P, a wheel is attached to the gear box, coupled with another gear wheel, tightly fastened with a stepped pulley B. At the end of the other, hollow, trunnion C, a gear wheel E (Fig. 1, 2 and 3) is hooked up, coupled through E- and z (Fig. 1) with a gear (Figs. 1 and 3), seated freely on the same trunnion C, and mechanism G (Fig. 1) for removing spines. Behind it are placed two guide rollers 5, and .Sa Two separating rollers 3s and 3, two drawing boards and // 2 and two drums M and M, on the axis

The gear K is mounted, driven by a worm gear on the shaft L, which, in turn, is rotated by gear E coupled to gear EI via gear E.

The mechanism for removing the spikes includes a sleeve T with a cam chuck U, fastened with gear j, a hollow stem C, which is free to sit at the end. Inside sleeve C is inserted a sleeve 5 with crosswisely arranged longitudinal grooves UJ for passing the spines. The sleeve / 7 is screwed to the very end of the trunnion C, inside of which the cams F-F are located (of which only F is visible on the drawing), rotating around the axes D - / j;, i, loaded with springs X - A and bearing the shaped cams on themselves Z / j - Z / 4 with processes that click on the bolt ring H; This latter is influenced by the springs H supported on the hub / V ring.

In the coil of the wire to be unwound, the end of the wire is unwound manually for about two meters; then, having strengthened the current on the axis O of the frame G, pass the untwisted ends of the wires through the hollow pin C, mechanism G, removing the prickles, and between the guide rollers 3 and further go around the separating rollers Zz to 3, draw the wires: boards and and //) and the ends of the wires are fixed on the reels M &a; L / a, after which the machine is activated. With one turn of the gear EI gear E and the parts of the mechanism connected with it, four turns are made for each step of unwinding the wire, which results in the removal or, more correctly, the unwinding of the spike nodes.

The subject of the invention.

Claims (2)

1. Machine for mechanical unwinding of barbed wire and removing barbs from it, characterized by the use of a mechanism for removing barbs (Fig. 3), which includes: a) freely mounted on a hollow shaft C of frame G 41 that is attached to the sleeve T and a cam chuck U, b) a sleeve B inserted inside the pin C with a cross-shaped longitudinal grooves W for the passage of spines; c) screwed onto the end of the pin C of the sleeve inside which the cams F1-F4 are located, turning around the axes - D, loaded with springs and bearing the jaws C - C with spikes that press on the slide ring H, loaded with springs And, resting on the hub ring / 7. 2. The form of the machine according to claim 1, which serves to unwind the wire, which includes: a) an iron frame D, which rotates on horizontal pins and carries the transverse axis O for a coil of barbed wire, the end of which passes through a hollow pin C (Fig. 2); b) gear s, which is wedged on pin C and causes the gear to rotate, through enumeration 2 and E, at a speed 4 times its own speed and c) a mechanism for straightening and winding the wire consisting of rollers 3i, per SB, 3i, drawing boards HI, U-, n drums M, MI, which are driven from gear K by means of a worm gear (Fig. I and 2).
