Abstract

The invention relates to devices for packaging piece goods or products, in particular agricultural products. The aim of the invention is to increase the reliability of the device in operation. A mesh harness is inserted into the loop shaper 4, and when the rollers 7 and 8 feed the wire 5, the latter in the loop shaper 4 bends around the strap, forming a clip, and then when the knife 11 is fed, the wire 5 is cut in the groove 10 and crushed in the loop shaper. The use of a device for the manufacture and application of a clip on a bundle of packaging net improves reliability due to the fact that the presence of a hole or a groove 10 in the guide 9 provides a high-quality cut of the wire 5, and the presence of notches in the stop head 3 and in the guide 3 - elimination of the jamming effect. 4 il.

The invention relates to devices for packaging piece goods or products, in particular agricultural products.

The goal of Hjo6peTeHHH is to increase the reliability of the device in operation.

Fig, 1 shows the device in the initial position, a general view; FIG. 2 - the same, in the position after the wire wrapping and crimping of the wire harness; fig.Z - node I in figure 1; in fig. 4 - section / i-A in fig; 3.

The device for the manufacture and application of the clip 1 on the packaging grid bundle comprises a base 2, a stop head 3 comprising a shaper 4 loops, a wire feed mechanism 5 from the coil 6 including rollers 7 and 8, a wire cutting mechanism 5 including a directional 9 with a groove or A bore 10 and a knife 11 with cutting edges and a mechanism for reciprocating the movement of the knife 11 are made in the form of two levers 12 and 13 that are hingedly connected to each other and the stem 14, fixed in turn, on the base 2. The lever 2 hinge 15 is associated with a base 2, and the spherical hinge 16 interacts with the hilt 17 of the knife 11. Additionally, the knife P is connected through the bracket 18 to the levers 12 by a spring 19, and the tail 13 is connected to the feed unit 20 hinged on the base 2. The feed block 20 also has a stop 21, a return spring 22 and a hook 23 serving to interact with the ratchet wheel (not shown) of the roller 7.

The device works as follows.

In the initial position of the device, the mesh end assembled into a bundle is inserted into the loop shaper 4 and the cylinder 14 is turned on, while the movable knife 11 moves along the guide 9 towards the loop shaper 4, and the feed unit 20 interacts with the hook of the roller 7, pushes the wire 5 through the groove 10 into the former 4 loops and forms a string around the bundle.

When the knife I1 is approximated to the groove 10, the loop formation is completed, the hook 23 leaves the interaction

with the tooth of the ratchet wheel of the roller and the feeding of the wire 5 is stopped, and the knife 11 on a further course produces a piece of wire 5 and the molding of the formed loop, forming a clip. Then the cylinder 14 switches back and the knife I1 returns to its original position, and the hook 23 of the feed unit 20 contacts its back part with the ratchet wheel of the roller 7, rotates on the axis, stretching the spring 22, passes the ratchet wheel without turning

roller 7 and 8, after which the spring 22 returns to its initial position before contact with the stop 21. During the execution of the operating cycle, spring 19 ensures constant contact of the cutting edge of the knife I 1 with the guide 9 and reliable and high-quality cutting of the wire.

The use of the proposed device for the manufacture and imposition

zalsima on the harness of the packaging grid,

wherein the loop former is formed by grooves on the adjacent surfaces of the stop head and the guide, and a groove is made in the guide

or the hole, the edges of which are the cutting edge, improves reliability due to the fact that the presence of the hole or groove in the guide provides a high-quality cut of the wire, and the presence of a notch in both the stop head and the guideway eliminates the jamming effect.
