Abstract

Tape packing sling, consisting of a lower supporting part, which is two circular branches, crossed and fastened together at the intersection and the upper closing part, connected on the package through rigid rings with branches of the lower part, with the formation of lifting loops, characterized in that the ring the branches of the lower part are crossed at an angle corresponding to the direction of the diagonals of the packet rectangle in the plan, and threaded through on each of the four branches formed, with the possibility of shifting joints along the tape, one rigid ring, by means of which every two branches of the lower part are connected on the package with one loop end of the upper part, which is one ring sling, with the formation of two lifting loops located on the sides of the package.

Description

Strap Tape

1. The device relates to technological equipment for cross-cutting work, namely: to packing tape slings for bag and bale goods and can be used in the formation, transshipment and transportation of packages of goods.

2. Packing slings are known, the set of which consists of a lower supporting part and an upper trailing part (UK patent No. 1 394 823 1, US patent No. 3, 701, 559 2, French patent No. 75 39773 3, US patent No. 4.448, 451 4 )

The lower part has four branches in various configurations.

- in the form of the so-called "clover leaf (Fig. 9 of the patent 1,394,823 and similar figures in the other mentioned patents);

- in the form of "rays diverging from one common center (Fig. 11 1). Practice has shown that with these two configurations the bottom

parts, branches of the sling when transporting packages converge in one line, which leads to a violation of the integrity of the packages. Somewhat better is the following execution of the lower part:

-in the form of two circular branches crossed at a right angle (90 °) and fastened together at the intersection (Fig. 10 1). The sizes of the packages in the plan are practically never equal, that is, in the plan the package looks like a rectangle, not a square. The location of the branches of the lower part at a right angle, and they start from the corners of the package, leads to uneven tension of the branches and reduces the reliability of compression of the package with a sling.

The upper part is made in the following main options:

- two annular, not crossed among themselves, slings - X-shaped four corner part 4, which does not have any

functional benefits.

The branches of the lower part of the sling are connected on the package to the upper part using self-tightening units (Clause 6 of Formula 1 and Figs. 3,4,5 4 or ring-links - (Clause 3 of Formula 1, with the formation of four lifting loops at the corners of the packet).

(more than 600 kg), because due to the high resistance in the self-tightening nodes, reliable compression of light packets with a sling is not achieved.

The closest to the claimed tape bundling sling for the totality of signs is the sling according to paragraph 7 of formula 1, the prototype, which in translation of this paragraph is characterized by the following features:

“A sling in accordance with any one of paragraphs 1 and 3-6, consisting of a four-branch part of constant length and two continuous loops with four loop ends, each secured by two pairs of tightening means to the four-branch part.

The prototype has four lifting loops located at the corners of the package, which requires four dowel operations, and, accordingly, four hooks of the load gripping device.

3. The task to which the claimed device is directed is to reduce the number of lifting loops to two, with their most convenient location on the sides of the package. In this case, the following additional technical results are also achieved: instead of two upper locking parts that are not fastened together, only one ring line is used, the number of metal rings is reduced from eight to four, reliable compression is achieved by the package line both around the perimeter from the sides and four bottom corners. Case compression is achieved even for relatively light bale packages.

These technical results are achieved in that, in contrast to the known tape sling 1, which consists of a lower supporting part, which is two circular branches, crossed at a right (90 °) angle and fastened together at the intersection, and two upper closing ring parts , each of the four loop ends of which is connected on the packet by four pairs of rigid rings with four branches of the lower line, with the formation of four lifting loops located at the corners of the packet, with a packing tape sling, the annular branches of the lower part are crossed under the corner corresponding to the direction of the diagonals of the package rectangle in plan, and on each of the four branches of the lower part formed, one rigid ring is moved along the tape, through which every two branches of the lower part connected on the bag with one loop end of the upper part, which is one annular sling, with the formation of two lifting loops located on the sides of the bag.

4. The essence of the proposed device is illustrated by drawings, which depict:

figure 4 The connection node of pairwise rigid rings with tape parts of the sling - side view.

5. The lower supporting part of FIG. 1 and the upper trailing portion of FIG. 2. The lower part consists of two identical circular branches 1 and 2, each formed by stitching 3 ends of a woven synthetic tape.

Branches 1 and 2 are crossed at an angle corresponding to the direction of the diagonals of the package rectangle in the plan. In practice, for most types of packages, the angle a is 65 ± 5 °. Tapes at the intersection 4 are fastened (spshty) among themselves. On each of the four branches formed 5, it is made with the possibility of moving along the tape along one rigid (metal) ring 6. The upper part 7 is one ring sling, which, as a rule, is sewn from two pieces of tape so that at the looped ends (lifting loops ) 8 formed two layers of tape to reinforce the most loaded section of the sling.

The assembly of the tape packaging sling on the package is carried out in the following order.

Units of cargo (bags, bales) are placed on the lower unfolded part of the sling - FIG. 1, after which the upper part - 7 is laid on top of the bag. The branches 5 are circled around the lower corners of the bag, and the rings 6 are aligned in pairs in the middle of the sides of the bag (the direction of alignment is shown by arrows in Fig. 1), due to the displacement of the rings along the tape, branches stretch evenly. Every two rings 6, on both sides of the packet, are looped through the loop ends 8 of the upper sling 7, which are known in a winding way - FIG. 4.

For the formed two lifting loops 8, the package rises. At the first lift, the package is evenly crimped around the perimeter from the sides and from the four lower corners. After lowering, the compression of the package of the sling does not weaken and the package is ready for transshipment and transportation.

The disconnection of the parts of the sling when the package is disassembled is carried out by spreading the rings manually or using known simple devices.

Tests made in the process of developing a utility model prototypes of tape packaging slings confirmed the receipt of the technical results specified in the section "The essence of the utility model. Reliable compression of packages of relatively light cargo loads was achieved, the cost of the sling was reduced, due to the reduction in the number of tops and metal rings, the time for forming and reloading packages was reduced compared to four-loop slings.
