Description

(5) DEVICE FOR CLOSING RECTANGULAR

PRODUCTS

one

The invention relates to packaging machines, in particular, mechanisms for completely wrapping rectangular products, which can be packaging boxes, cardboard boxes, etc., and can be applied in post offices of the USSR, in food processing and trade enterprises, as well as in other enterprises packing products into rectangular packagings of small dimensions.

The known device for wrapping rectangular products includes roll holder for wrapping tape installed in a row, a mechanism for applying glue to a tape with rollers, a knife mechanism with a plate, a mechanism for feeding the tape and a rotor with four pairs of shelves and bending tools for tape LIT.

Such a device is not sufficiently reliable for operation and efficiently, and also does not ensure complete banding of the boxes. Due to availability

two sets of devices for feeding the tape and plastering it with glue, the device is excessively bulky and bulky. A complex lever system prevents the achievement of high device performance. The supply of glue to the tape device is unreliable due to frequent pipe clogging and transfer fittings. In addition, the supply of wrapping tape is difficult.

The aim of the invention is to increase operational reliability by facilitating the supply of wrapping tape to the rotor.

To achieve this goal, a device for wrapping rectangular products containing a roll holder for a wrap tape installed in a row, a mechanism for applying glue on a tape with rollers, a knife mechanism with a plate, a mechanism for feeding the tape and a rotor with four pairs of shelves and a bending roll mi for tape.

the rotor shelves are freely mounted on axles and with a gap between the shelves in each pair for the tape passage, and the tape feed mechanism consists of a grab, which is mounted for movement perpendicularly to the rotor shaft, and a movable plate located under the blade of the knife mechanism, in which a hole is formed for the passage of the plate, wherein the rotor bendings consist of two pairs of rollers mounted for movement in vertical and horizontal planes.

The drawing schematically shows the proposed device.

The device comprises a roll holder 1 for paper tape 2; iiiehanism 3 filing glue; feed rollers 4 and 5. One of which k wets with glue one side of the tape, the movable plate 6; the stationary plate /. the performing function of the fixed blade of the cutting mechanism, through which the movable plate passes, performing a reciprocating motion in the vertical plane; cutter 8; feed mechanism 9 with a folding gripper 10; frame 11; two pairs of winding rollers 12 and 13 having the ability to move sequentially in the vertical and horizontal planes; a tilter consisting of two crosses 1A, performing synchronous rotational movement by 90 during each cycle and provided with swinging shelves 15 and 16.

The tape end of the roll holder is preloaded between rollers k and 5 to the cutting edge of the stationary plate. A movable plate lifts the edge of the tape over this plate, allowing the fold-back grip to hold the edge of the tape. The latter is fed into the working area of the feeding mechanism and rests on the rollers 12 and 13. Then the gripper releases the end of the belt and the feeding mechanism departs from the operation 958174

whose zone is in its original position. The cutter cuts off a measuring piece of tape. The tilter, in shelves 15 and 16 of which item 17 is laid in position t, transfers it to the working area (position W). The product lies on the adhesive-coated surface of the tape. The rollers 12 and 13 alternately roll the tape to the surface of the product and go to the original

to position. At the position and / or the graded article, it is discharged from the turner and the banding cycle ends there.

The proposed implementation of the device facilitates the filing of the wrapping tape to the rotor and increases the reliability of its work.
