The invention relates to packaging technology and may be used for labeling, such as cans. A device for labeling labels on flat surfaces of products containing vacuum grippers for removing labels from a store, a glue-applying mechanism and a distributor of vacuum and compressed air is known. The disadvantages of this device are design complexity and not reliable operation due to the fact that the angle 90 of the entire system of working bodies during the cycle of labeling a single label with the help of a pneumatic cylinder does not: it invariably causes dynamic impacts against the stops at the time of stops, but a vacuum-grip made in the form hollow shtoka obliquely cut may not be in contact with the entire label surface. It is also known a device for labeling labels on flat surfaces of products, consisting of shops for labels coaxially mounted with them with the possibility of reciprocating movement of the heads for extracting the transfer and labeling of labels, an adhesive mechanism, a transporting body for moving articles and a stand C2. . The disadvantages of the known device are low productivity and the absence of locking mechanisms. The purpose of the invention is to increase the device performance and the ability to lock the device in case there are no labels and no labels and no labels and no adhesive. The goal is to get a known label sticker. on flat surfaces of products consisting of stores for etiquette coaxially mounted with them with the possibility of reciprocating movement of the heads for removal, transfer and sticking Vani labels, conductive glue applicator mechanism, the conveying organ for moving articles and the frame is provided with a rotor, and stores labels for fortified and coaxially with them are mounted on the rotor head, wherein the head mounted on the rods, the lower ends of which are for rollers. movement along the copier mounted on the frame — and the transporting body for moving articles is a cassette conveyor mounted so that in the zone of engagement with the rotor the cassette is located between the magazine and the head. At the same time, it can be equipped with a mechanism for fixing the head in the extreme upper position and associated locking mechanisms. No products - no label and No label - no adhesive applied. Heads are equipped with a spring-loaded manifold having cylindrical protrusions with channels and installed in a sleeve. The mechanism for fixing the head consists of a rotary latch with a roller and a ball lock. FIG. 1 shows the proposed device, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B in FIG. 2. The proposed device consists of a rotor 2 mounted on the base 1, coaxially mounted along its circumference around the heads of 3 liters of magazines 4 for labels of a cassette conveyor. 5f gluing mechanism 6, locking mechanism 7 No product -. no label, locking mechanism 8 No label-no adhesive, with head 3 fixed on rods 9, having rollers 10 running at the lower ends running around copier 11 and fitted with a manifold 12 having cylindrical projections with clamps installed in sleeve 13 and a spring-loaded spring 14. The mechanism for fixing the rods 9 consists of a rotary latch 15 with a roller 16 and a ball retainer 17, which interacts with the rods installed on the rods 9 and the sleeves 18 with the shoulders. The device works the next time. Through pipes 19 and 20, air is compressed and a vacuum is created. Bring the rotor 2 and the associated cassette conveyor 5 into rotation. In the conveyor cassette 5, the labeled products — banks 19 — are placed in the cassette. In sector a, i.e. in the zone of engagement of the conveyor 5 with a star 21 of the rotor 2, the cassettes with banks are located coaxially under the heads 3 and above the magazine 4 and have synchronous movement with them. In sector a of head 3, the labels with adhesive applied to them, together with the pins 9, rollers 10 of which are rolled around the copier 11, are lowered onto the lids of the cans and glued to the labels with pads 22. At the same time, the vacuum is turned off and compressed air into the manifold 12, improving the fit of the labels to the roofs of the cans. At the exit from sector a, the heads 3 are raised to the uppermost position, lr. Continuing to move around the circumference, and the labeled cans at the conveyor belt between the rotor 2 and the guide sprocket 23 are pushed onto the diverter conveyor with the aid of a bar fixed with an angle to the direction movements of the conveyor cassettes 5 Each head 3 after the next labeling in sector a, moving around the circumference of the rotor; 2, together with the studings 9 and rolling the roller 10 along the copier 11, after leaving the conveyor 5 from under it, lowering it with the slide 22 into the stoppers 23 of the magazine 4, touching the upper label. At this moment in the distribution distributor 24, in the flexible hose 25 and in the manifold 12, a vacuum is required for removing the label. With further movement, the head 3 begins to rise and the label is removed from the store 4 while simultaneously blowing it from the downstream labels as the store 4 passes by the air nozzle 26. Next, the head 3 with the received label rises to its extreme upper position in the label control section, then The bottom of the roller ridge 27 of the mechanism — for applying adhesive 6 — is lowered. When the label head 3 passes over the mechanism for applying adhesive b, the roller ridges 27 carrying the adhesive are rolled along the label b sliding of leaving the adhesive strip on the reverse side of the label. After applying glue to the label, the head 3 continues to move at the same height above the conveyor 5, in the cassettes of which there are cans to be labeled. When entering the sector, the head 3 is lowered, putting a label on the can and the cycle of operations repeats. In order to eliminate the receipt of the label by the head 3 from the magazine 4, applying glue to it and discharging it with compressed air in sector a into a cassette in the absence of a can to label, which is characteristic for the beginning or end of the machine, and can also happen during operation the machine with skips loading due to the uneven supply of cans, in my mother's automatic lock is provided. No products-no label-. During the operation of the machine, the hub 28, whose roller rolls around the annular cam 29, makes a swinging motion, slide over each conveyor belt 5. If there is a can in the cassette, the lever 28 lowers until it stops with a rubber elastic roller 29 into the can lid and rolls along it, not giving a signal to trigger the lock. When there is no canister in the cassette, the lever 28 drops lower than when there is a can, the lever 28 opens the photocell (not shown), which gives the command to activate the locking mechanism 7, the striker of which strikes the roller 16 by moving the latch 15 under the collar of the sleeve 18 fixed on the corresponding empty cassette of the rod 9, which is lifted to the extreme upper position by the cam 11 at this moment. As a consequence, the head- 3, fixed on this. rod 9, with further movements almost a complete revolution of the rotor rises fixed in the extreme Eern. tension, i.e. It does not lower to remove the label from magazine 4 and passes with a gap above the glue-applying mechanism 6. From the sector out of the sector a, the roller 10 of the rod 9 with the head 3 attached to it is placed on the profile section of the cam 11 corresponding to the extreme upper position of the head 3 and the load of the sleeve of the sleeve 18 to the latch 15 is removed, after which the copier

29, I act on the roller 16, moves the latch 15 to its original position with its fixation with a ball retainer 17, preparing it for the next interlock action.

To eliminate the possibility of applying glue to the surface of the cushion 22. in case the label is not removed for any reason by the head 3 from the magazine 4, the machine has a locking mechanism 9 No label does not apply glue. In this case, after lowering the head 3 to Mairazin 4 and lifting to the uppermost position to control the presence of the label, the photocell 30 gives the command to activate the mechanism 8 locks 10, which sets the latch 15 under the collar of the sleeve 18, t, e. upon further movement, the cushion 22 of the head 3 passes with a gap above the glue-applying mechanism b and upon exiting the sector and the latch 15 is reset to its original position as described above. the locking mechanism 7 is triggered No product — there is no label and there is no label head on the pad 22, the locking mechanism 8 locks No label — no adhesive does not occur because the photocell 31, when the latch 15 is installed under the collar of the sleeve 18, does not release the command to turn on the locking mechanism 8 electromagnet for the head 3. The level of glue in the bath of the glue-applying mechanism b is ensured when the machine is operated by feeding glue with a diaphragm pump driven by rotational transmission of the flexible roller 32. In this case the pump The glue from tank 33 is transferred to the bath of mechanism b through a flexible hose in an amount exceeding the consumption of glue. The excess glue through the fitting located in the wall of the glue bath at the working level is drained back to the tank 33 via a flexible hose.

0 The active circulation of glue with its limited contact with the air of the environment prevents the formation of films and clots.

Expected economic effect
