SU914414A1 - Method of bundling stacks of articles with endless band - Google Patents

Description

The invention relates to the technique of handling unit loads, in particular to the strapping of packages of these goods, with the aim of mechanization of loading and unloading operations during transport by various types of transport.

There is a method of strapping a package of objects with endless ribbons, involving the formation of a package of objects on a supporting tape with loops, the imposition on the package of objects of a closing tape with loops and the connection of loops among themselves (1).

The disadvantage of this method is a significant consumption of the binding material due to the large (relative to the perimeter of the fastened package) dimensions of the closing and carrier loops, which in turn leads to the formation of lifting loops of great length. The latter circumstance is the reason for the difficulty of carrying out transshipment work in rooms with low altitude.

The purpose of the invention is to save banding tape by reducing its length.

This goal is achieved by agreeing to. But the method of tying a package of objects.

* endless ribbons providing for the formation of a package of objects on the supporting tape with loops, the application of locking tape with loops to the package and the connection of loops among themselves, after applying locking tape to the package of items of locking tape, pass the sling with rings into each loop, which then draw through supporting belt loop to the output loop of the closing belt, the hinge strap after the connection with the rings removed from the loop _I eamykayu tape.

positioning and loading of an additional line through the lock strapping on the package; in fig. 4 - the first turn of the additional line around the supporting harness; in fig. 5 “scheme of formation of the lifting loop after pulling the additional binding around the support · by an additional sling; FIG. 6 is a diagram of the formation and tightening of the locking connection of the lifting loop before removing the additional sling.

To create a package that meets the requirements of keeping its density and shape, a harness consisting of two loops is used: supporting 1 and closing 2, Both loops are tape segments, stitched or connected in closed rings by nodes 3 · The total length of the straps is less than the perimeter of the package covered .

The locking harness 2 is wrapped and tightened around the supporting 1 and vertical portions of its own branches from the sides of the bag so that it forms locking joints 4, holding the tapes in a fixed position, and lifting loops 5.

The method is as follows.

On the flat surface or on a pallet with slots, the supporting harness 1 is laid out so that its branches are parallel at a distance of 2/3 of the length of the units of the cargo being packaged (Fig. 2). Then the load is laid on the strapping in parallel rows. The ratio between the length of the supporting strapping 1 and the number of packaged units of cargo must be such that when covering the package from the sides, the locking connections 4 before fitting would be between the top and second from the top, units of cargo,

An additional straps 2 are placed on top of the stacked bag, and then additional straps 6 (FIG. 3) are pulled into the locking straps on both sides of the packet (fig. 3), and the joint ends of the additional straps with ring-shaped loops 7 are pulled around the supporting straps.

In loop 7 an extra sling. lay the hook 8 of the lifting mechanism and the package is raised. In this case, the lifting loops 5 freely twitch around the supporting harness 1. A tight tightening occurs.

package. At the same time, by twisting the loops 5, the natural stretching of the strapping tapes and its cutting into the load is compensated (bags, bales

5, etc.).

After lifting the package is lowered, the loops 7 of the additional sling are removed from the hooks 8 and, without dissolving the connection, the lifting loop 5 is wrapped

1Θ around the strapping branches 2 (FIG. 6). Then the package is raised again with the help of a lifting mechanism. When the package is lifted, the lifting loops wrapped around the supporting strapping and closing strapping branches are finally tightened, forming a locking connection 4. The formed package is lowered, and additional Slings are removed for use when forming the following packages.

Synthetic tape LTK 501600, TU RSFSR 2703-74, the cost of

25 1 m tape 0.48 rub.

The results of the calculation of economic efficiency show that the proposed method of tying packages of packaged piece goods using woven

30 tapes, for example, synthetic, in comparison with the known, allows to reduce the consumption of binding material per package by 2 m, and the cost by 0.96 rubles.

Claims (1)

Claim A method of tying a package of objects with endless ribbons, involving the formation of a package of objects on a * supporting tape with loops, the imposition on the package of objects of a closing tape with loops and the connection of loops between each other, characterized in that it is economical. strapping tape by reducing its length, after applying a closing tape on the package of items to each loop of this tape, pass a sling with rings, which are then ⁵⁰ pull through the loop of the supporting tape to the exit loop of the closing tape, while after connecting the loops, the sling with the rings is removed from the loop of the closing tape.
