(54) DEVICE FOR PACKING RING PRODUCTS

I

This invention relates to the wire manufacturing industry.

A device for packing wire coils is known, which contains flexible shuttles installed in closed guides, and on the flexible shuttles band-laying machines made in the form of rolls with a supply of packaging materials 1 are fortified.

The known device carries a limited supply of packaging materials, which necessitates frequent change of coils and preparatory operations for pre-winding material on the rolls, which, ultimately, drastically reduces the performance of the device.

It is also known a device for packing ring-shaped products, comprising mechanisms for feeding and rotating products and a mechanism for wrapping products having two parallel chains and a paver 2.

However, in the known device filling the packaging material in the paver for-. difficult, so the performance of this device is low.

The purpose of the invention is to improve the performance of the device and its operation is more convenient.

To achieve this goal, the paver consists of two pairs of parallel plates, one inside the other and hinged on the chains of the mechanism for wrapping products, with one of the pairs of plates moving relative to the other pair, and the plates in each pair are interconnected by a roller for packaging material and one of the plates of the fixed pair has a lock for one of the plates of the moving pair.

FIG. 1 shows the described device, axonometrics; in fig. 2 - that. same, in the preparatory period; in fig. 3 the same at the beginning of the work cycle; in fig. 4 - the same, during the transfer of packaging material to the product; in fig. 5 - band paver, axonometrics.

The device for packing ring-shaped products contains a multi-site mechanism 2 installed on a common base, equipped with several pairs of support rollers 3, 37 serving to transfer the products 4 to the wrapping zone and to rotate them during earing. The device also includes a reel 5 with packaging materials 6, mounted on axis 7, and a product wrapping assembly, which is a flexible shuttle made in the form of two open circuits 8 and 9 connected by rollers 10 serving to transfer the packaging material 6 from reel 5 on product 4. Chains 8 and 9 carry a paver consisting of a system of movable parallel plates 11-14, mounted in pairs on axes 15 and 16, arranged in a single line and rigidly fixed on links 8 and 9. Plates 11 and 12 on x 15 and 16 are fixed and with The rollers 17 and 14 are interconnected by a roller 18 and are movably mounted on axes 15 and 16. The rollers 17 and 18 when they are closed are used for braking and guiding the packaging material 6 when transferring it to the product 4, the Plate 11 carries the latch 19, made in the form of a pivot arm of the 1st kind, mounted on the axis 20 and spring-loaded relative to the plate 11 with a spring. For closing and unlocking the system of plates 11 14 serve as a copier 22 and an emphasis 23 mounted on the base I. Plate 13 for interaction with lock 19 performed with groove 24, and for interacting with copier 22 is equipped with a pulley roller 25. Chains 8 and 9 are installed in closed guides, the contour of which is formed by the lower fixed parts 26 and the upper - sliding parts 27. The latter are fixed on the carriage 28 moved the drive 29 along the rolling pins 30. The fixed portions 26 mate backup guides 31, and in the places of their intersection there are installed paired controlled turnouts, made in the form of U-shaped swing arms 32, covering said guides in the spaces x interface (not shown). Chains 8 and 9 are set in motion in the guide sprockets 33. The device operates as follows. The U-shaped arms 32 are mounted horizontally and chains 8 and 9 are distilled into reserve guides 31. After that, the actuator 29 retracts the carriage 28 with the extended parts 27 to the extreme right position, at the same time the closed guide rails crumble, opening access to product 4 to the wrapping unit. By the multiplace mechanism 2, the article 4 in dits is in a wrapping unit. The packaging material is unwound from the roller 5, passed between the rollers 17 and 18 of the open-top paver and secured to the product 4. With the actuator 29, the sliding guides return to the far left position, forming a closed loop with the fixed parts 26. The sprockets 33 of chains 8 and 9, the carrying rollers 10 and the paver, come out of the backup guides 31 and start moving in a closed cutter, on the way to which the copier roller 25 interacts with the wedge surface of the copier 22, shifts the plates 13 and 14 upwards, the rollers 17 and 18 are closed, braking and directing the packaging material 6 when transferred to the product. When the roller 25 descends from the wedge surface of the copier 22, the movable pair of plates 13 and 14 remains fixed relative to the stationary pair 11 and 12, since the latch 19 has stuck 13 into the groove 24. After passing the last links of chains 8 and 9 under the U-shaped levers 32, the latter are lowered and the KOHTjp guides are finally closed. Simultaneously with the beginning of the movement of the chains 8 and 9, the support rollers 3 start to rotate and, consequently, the product 4. When the chains 8 and 9 are closed, closed by a guide loop, the packaging material 6 is transferred from the coil 5 to the product 4. The amount of overlap is established by agreeing on the speeds of the sprockets 33 and the support rollers 3. After packing part of the product 4, the packaging material is cut and further packaging is carried out by stocking the packaging material on the rollers 10 of chains 8 and 9. At the end of the process the rotation is followed by a command to stop the support rollers 3 and horizontal installation of the U-shaped arms 23. Then by reversing the sprocket 33 chains 8 and 9 are distilled into reserve guides 31. In the extreme right position, the latch 19 of the paver, pushing against the stop 23, exit from groove 24 of the plate 13, freeing the last. The plates 13 and 14, as well as the guide roller 18, which binds them, under the action of its own weight, are lowered downward, revealing the palm loop. Next, the actuator 29 carriage 28 moves / s to the extreme right position. The free end of the packaging material is fixed on the packaged product 4, after which the mechanism 2 carries it away from the wrapping unit, delivering the next product to its place. Then the cycle is repeated. Due to the fact that the paver is made self-separating in the device, the losses for preparatory operations for filling packing materials decrease, and this, eventually, as shown by experimental testing, increases productivity by approximately 15-20%.
