The invention relates to a device for you to apply a belt tension and to tie up ring-shaped objects by it, can be used in various parts of the national economy, especially in the pin industry for tire packaging, and is complementary to the basic model. St. No. 1244028,

The purpose of the invention is to improve the reliability of the device by ensuring that the cut end of the tape is pressed against the article being knitted by tightening and tensioning the polypropylene tape before welding its ends with a pressure elastic plate.

On 4ig. 1 shows a device for ringing ring-shaped articles; the general view of FIG. 2 is a section AtA in FIG. one; in fig. 3 - clamp unit; in fig. 4 is a view B in FIG. 3; in fig. 5 — sequence of operation of the tape end mechanism; in fig. 6- mechanism for gripping the end of the tape; in fig. 7 shows the position of the fur: the bottoms of the device at the time of the formation of the binding loop of the tape; Figs. 8, 9, and 10 are stages of the formation of a binding loop.

The device for tying ring-shaped products comprises a frame 1 on which a carriage 2 is installed (figure 1).

The carriage 2 contains brackets 3, at the end of each of which is placed on the belt feed mechanism (FIG.) Containing the rollers 4 and spring-loaded L-shaped lever Z.

On the bracket 6 of the carriage 2, a pneumocilloid yarn 7 is fixed, interconnected through the rod 8 (Fig. H), the link 9, the levers 10 with t 11 and 11 (Fig. 5),

A mechanism for capturing the end of the tape (Fig. 1, 2) is installed on the bars 11. The mechanism 12 for gripping the end of the belt; (Fig. 1, 2) includes a pneumatic-cylinder 13 (Fig. 1.7) fixed on the base 14 (Fig. 1.6), and a slider 15 movably mounted on it (Fig. 6), interconnected with the rod of the pneumatic cylinder 13 (Fig. 1.7).

. The base 14 (Fig. 1.6) has a fixed sponge 16, and the slider 15 has a movable sponge 17 (Fig. 6).

The reel 18 with the packing tape 19 and the guide rollers 20 are mounted at an angle of 120 at the rear end of the caret 2 (Fig. 1, 2).

The pneumatic cylinders 21 (Fig. 2, 7), which serve to drive the carriage 2, are attached to the frame 1 (Fig. 1).

On the bracket 22 (fig, 7) of the frame 1 (fig „1) are located the joints 23 for joining and welding the tape, as well as the mechanisms for cutting the tape.

On the brackets 3 of the carriage 2 (FIG. 1), between the shoulders of the L-shaped lever 5, there are fasteners 25 (FIGS. 1, 4, 7), which have clamping elastic plates 26 (FIGS. 1, 3, 7) fixed by one End on bracket 3, and the free end located along the large shoulder of the L-shaped lever 5

The plate 26 is made of medium-hard rubber and, for example, with regard to the bound motorcycle tires 3.75-19, has the following dimensions: length — 200 mm, width — 800 mm, thickness — 8 mm.

The ring strapping apparatus operates as follows.

From the reel 18, the packaging tape 19 is pulled manually along the guide roller 20, and then fed to the tape feed mechanism (Figs. 1, 6).

The pneumatic cylinder 7 (Fig. 5) is put into operation and with the help of the rod 8, pushes the levers 10 through the link 9 (Fig. 5), which in turn spread the rods 11 (Fig. 5) in the radial direction from the center and bring the jaws 16 closer. and 17 (Fig. 5,6) to the tape feed mechanism (Fig. 5).

The jaws 16 and 17 abut against the end of the stem 27 (FIG 6) of the belt feeding mechanism (FIG. 5, 6), which compresses the spring 28 (FIG. 6) moving in the radial direction from the center, and the end 29 of the tape 19 (FIG. 5, 6) when this comes out of the groove 30 of the rod 27 (Fig. 6) and is in the gap between the jaws 16 and 17 (Fig. 6).

The pneumatic cylinder 13 of the gripping mechanism 12 (Figs. 1, 5, 7) works, moving the slider 15 with the sponge 17 in the direction of the sponge 16, clamps the end 29 of the tape 19 (Fig. 6) between the jaws 16 and 17.

The pneumatic cylinder 7 then returns the levers 10 and the gi 11 to the initial position, and the end 29 of the belt 19 is clamped in the jaws 16 and 17, while the belt 19 is unwound from the reel 18.

In this position, when all three tapes are tensioned, the pneumatic cylinder 21 (Fig. 2.7) is used to insert the carriage 2 into the package 31 of the ring-shaped products 32 (Fig. 7), and the clamped ends 29 of the tape 19 in the jaws 16 and 17 extend from the mechanism; garden tape to the center. Simultaneously with the insertion of the carriage 2, the binding loops 33 form from the tape 19 on the bag 31 itself (Fig. 7). Yu

The tension of the belt 19 in the process of forming the loop 33 is ensured by the fact that the belt 19 drawn out of the feed mechanism all the time is in a position pressed against the outer surface of the bag 31.

At the same time, the bag 31 is compressed by the gland (not shown) to a certain size along the length

at the top, cutting the tape occurs at this time, then overlapping its ends (FIG. 9) and welding (FIG. 10). Thus, after the tape 19 is cut by the trimming mechanism 24, its end is fixed, making it possible to perform an overlap well.

After welding the ends 29 of the belt 19, the carriage 2 is returned to its original position by the pneumatic cylinder 21, releasing the bound package.

The proposed device allows to increase the reliability of the device in the process of forming a package of products due to the tension and holding the cut ribbon in the tensioned state by pressing, which makes it possible to precisely

In this case, the established degree of compression of the 20 overlap of the tape and to produce a cap in the bag must ensure its rigidity and at the same time not affect the quality of the tires. Packet compression ratio is recommended up to 8% of the total package size along its length.

The feed mechanism of the tape (Fig. 7) reaches the mechanisms 24 for cutting the tape and the node 23 for joining and welding the tape (Fig. 7), during which loop 33 assumes the position as shown in Fig. 8.

Before the overlap of the belts is performed by the pneumatic cylinder 13, the sponge 17 (fig. 1, 6) is retracted to its original position, freeing the end of the belt, and
