Description

The invention relates to the field of labeling of non-planar surfaces, namely, the attachment of self-adhesive labels by rolling on vessels, for example, bottles filled with liquid, including without overpressure, or other containers.

Various devices for sticking labels are known in the art.

Known labeling unit for bottles according to patent US 4192703, 1980, in which opposite the elastic rolling strip are adjustable guides that can be fixed by screws in a position corresponding to the diameter of the product on which the label is applied. The rolling strip rotates at a speed of approximately two times the speed of the conveyor belt with the products. The label, which is applied to the cylindrical product, is wrapped around the product, which rotates relative to the guides, while the label is pressed tightly and attached to the product by pressure of the outer surface of the rolling strip.

CN 105000236, 2015 describes a rotational labeling machine with a planetary disk, which comprises a conveyor belt for transporting bottles, an adjusting screw and a support plate for bottles, as well as sequentially arranged label feeding mechanism, marking means and label alignment mechanism. The marking means comprises a label sticker plate and a label alignment mechanism including an alignment roller pressing the label to the bottle, a first driven wheel, a drive wheel and a drive. The leveling roller can change its position, if necessary, if the diameter of the bottles on which the label is applied changes, which allows you to re-set this device and use it to stick labels on bottles of different diameters.

ее оборота.A device for gluing labels applied to the surface of a tape and having an adhesive layer (self-adhesive labels) is known, according to patent RU 2301765, 2007. The device includes a knot for rolling a label on a circular surface of a container, a knot for changing the radius of twisting of the tape depending on the radius of winding the tape on a roll, a unit for changing the tension force of both branches of the tape before and after the separator, a unit for changing the angle of rotation of the tape on the separator. During its movement, the container runs into the extended part of the label, presses against it with the force provided by the roller, and adheres to the label. With further movement of the container, it pulls out the remaining part of the label along with the tape, and the released tape is reeled up by the receiving drum. A container with a label attached to it drives the smoothing unit of the label, while the lever rotates the fist and groove around the fixed center. The fist and groove profiles are made in such a way that the lever with the roller is constantly pressed in the surface of the container as it moves along the assembly, which ensures that the label is pressed against the container and is smoothed over the container circumference to

her turnover.

The closest analogue of the claimed invention is a device for smoothing, intended for use in a labeling machine Gernep brand Labetta 16-640 2SK, Germany. As a means for smoothing labels, the manufacturer proposed several options: a smoothing edge with a soft substrate; or sponge rollers; or sponge rollers and polyurethane plates with brushes, or a polyurethane plate and a smoothing edge. These solutions are also widely used on machines of other manufacturers: Kronec; KHS; Sakmi; RE; SMI The option, including a polyurethane plate and a smoothing edge, provided the most high-quality result, but not to the full extent, periodically there were defects in the form of non-glued sections.

All the above solutions (analogues, including the closest analogue) do not provide the required quality of label sticking. This is due to the fact that when using a bottle with a non-cylindrical shape, for example, rectangular in cross section, and in particular if there is no excess pressure inside the bottle after filling the water with water, it is possible that the label is unevenly pressed to the surface of the bottle and, accordingly, the appearance of non-glued areas.

The technical problem solved by the invention is the elimination of the shortcomings of the closest analogue, namely, the quality of the product after applying a self-adhesive label to the bottle should be such that even small non-glued areas (double-sided label) should be absent when visualizing through a transparent bottle. Non-glued areas that do not fit snugly against the bottle wall are visible as defects - dark spots.

The solution to the technical problem posed is to improve the smoothing device for the labeling machine in such a way that the smoothing plate would ensure that the label is pressed against the bottle almost simultaneously with the moment the label touches the bottle wall and does not deform under the action of a moving bottle (container), on which the label is glued, moreover, there may be no excess pressure in the bottle, i.e. the wall of a bottle filled with liquid may sag under the influence of external pressure.

The smoothing device for the labeling machine is made up of means for pressing and smoothing the label and means of attachment to the elements of the labeling machine. Means of attachment to the elements of the labeling machine are formed by upper and lower levers fixed with the possibility of their angular movement by one end on the element of the labeling machine and the other end rigidly fixed on a vertical threaded rod, the upper and lower levers being rigidly interconnected by pressure, in addition, the fastenings to the elements of the labeling machine contain a bracket designed to fix on it a regulator of the pressing force of the smoothing plate and having means for securing Insulation to the element of the labeling machine. The means for pressing and smoothing the labels are made in the form of a rigid, predominantly metal, smoothing plate fixed to a vertical threaded rod, and a pressure force (pressure) regulator for pressing the smoothing plate and bevelled for interaction with the label. The force regulator of the clamping plate smoothing installed with the possibility of interaction with the smoothing plate through the clamp.

The smoothing plate is mounted on a vertical threaded rod by means of an intermediate element with nuts screwed onto a vertical threaded rod equipped with a handle, while the smoothing plate is made with horizontal slots in which threaded elements are connected connecting the smoothing plate with the intermediate element. In addition, the smoothing plate is mounted on a vertical threaded rod, preferably at an angle to the longitudinal axis of the pressure controller of the pressing force of the smoothing plate.

The force regulator of the clamping plate of the smoothing plate can be made in the form of a cylinder with a spring placed in its cavity, acting at one end on the output rod interacting with the clamp, and the other abutting against the spring pre-compression regulator. The clamping of the clamping force regulator on the fixed element of the labeling machine can be carried out by means of a clamp consisting of a plate and bolts with nuts, which ensure the clamping of the element of the labeling machine between the bracket and the plate.

The technical result achieved by using the invention is that it provides an improvement in the quality of sticking of self-adhesive labels due to the prevention of defects during label sticker, which is achieved by guaranteed constant pressing of the label to the surface of the bottle (or other container), starting from the moment the surface of the bottle is touched , due to the fact that the formation of non-glued areas - air bubbles between the surface of the bottle and the inner surface of the label is excluded.

The specified technical result is achieved by performing a smoothing plate rigid, while the rigidity of the plate must be such as to exclude elastic deformation (deviation) of the plate under the action of a moving bottle (container), on which the label is glued, in addition, the device is configured to adjust the position of the plate to smooth out in the horizontal plane and the angle of its inclination in the vertical plane (relative to the bottle wall), as well as the gap between the smoothing plate and the plate labels and the contact force to the bottle label by smoothing plate, which also allows to change due to the mutual arrangement of the elements to obtain the optimal setting, which provides high quality of gluing.

The smoothing device for the labeling machine is mounted on the fixed parts (elements) of the labeling machine and includes a vertical threaded rod 1 on which a rigid smoothing plate 2, mainly metal, as well as the upper 3 and lower 4 levers attached at one end to the fixed part of the labeling are fixed machines with the possibility of their angular movement, and the other end by means of nuts 5 and locknuts are rigidly connected to a vertical threaded rod 1. Upper 3 and lower 4 levers gesture of interconnected clamp 6 disposed vertically and are able to together with holder and a vertical threaded rod 1 to rotate about a vertical axis to the mounting element of the labeling machine. On the bracket 7, also attached to the fixed part (element) of the labeling machine, a pressure regulator 8 of the pressing force of the smoothing plate to the surface of the bottle (container) on which the label is applied is mounted and fixed. In this particular example, the regulator 8 is spring-loaded, however, the design of the regulator may be different (not only mechanical, but also pneumatic or hydraulic).

In the above example, the pressure regulator 8 of the pressure of the smoothing plate is made in the form of a cylinder 9, mounted on the bracket 7, with a spring 10 placed in its cavity, acting one end on the output rod 11, interacting with the clamp 6. The amount of pressure (pressure) of the pressure of the smoothing plate 2 is regulated by pre-compression of the spring 10, which is provided by screwing in / out of the controller 12 pre-compression of the spring, interacting with the other end of the spring 10.

The pressure force (pressure) regulator 8 is fixed to the stationary part (element) of the labeling machine using a clamp consisting of a plate 13 and bolts 14 with nuts, which ensure the clamping of the labeling machine element between the bracket 7 and the plate 13.

The smoothing plate 2 is mounted on the vertical threaded rod 1 by means of an intermediate element 14 with nuts screwed onto the vertical threaded rod 1. The smoothing plate 2 is made with horizontal slots 15 in which threaded elements (bolt joints) are connected connecting the smoothing plate 2 with the intermediate element 14 The horizontal slots 15 allow, if necessary, to move the smoothing plate 2 in the horizontal direction relative to the vertical threaded rod, and those m thereby changing the gap between the smoothing plate 2 and the label removal plate (not included in the design of the claimed invention). To do this, first loosen the bolt nuts and move the smoothing platinum 2 to the desired distance in the horizontal direction.

The angular position of the smoothing plate 2 is adjusted by loosening the lock nut of the nuts 5, with which the upper 3 and lower 4 levers are fixed on the vertical threaded rod 1, with the subsequent rotation of the vertical threaded rod 1 together with the smoothing plate 2 by the required angle relative to the axis of the adjuster 8 of the pressing force of the smoothing plate . For ease of rotation of the threaded rod 1, it is equipped with a handle 16.

To prevent damage to the label, the smoothing plate 2 is made with a chamfer 17 at the end, designed to interact with the label.

The work of the smoothing device as part of the labeling machine is as follows.

The tape with labels is wound into a roll and mounted on the roll holder, while the free end of the tape passed through the tension unit adheres to the label removal plate, then deviates from the edge of the label removal plate and, after removing the label (s), is wound on the drum.

The bottle on which the label is applied (or another container, for example, a can, etc.) moves in the direction of the smoothing device, rotating around its axis, while the sensor turns on the tape drive and it moves to the distance of the label size. Due to the tension of both branches of the tape and the corresponding angle of deviation of the tape coming from the edge of the label removal plate, the front part is separated from the tape and moves in the direction of the bottle (container), the tape moves at the same speed as the bottle (synchronously), and the bottle comes into contact with the front of the label and simultaneously with the chamfer 17 at the end of the smoothing plate 2.

The smoothing plate 2, which has rigidity that prevents its deformation upon contact with the bottle, remains in an unchanged fixed position, including when it comes into contact with the surface of the bottle (through the thickness of the label) and beyond. The smoothing plate 2 presses the front of the label to the surface of the bottle, thereby starting the process of gluing and smoothing the self-adhesive label. The regulator 8 of the pressing force of the smoothing plate 2 to the surface of the bottle provides constant guaranteed compression of the label on the bevel 17 of the smoothing plate 2 to the surface of the bottle, while the label is constantly pressed due to the impact on the clamp 6 of the output rod 11 of the regulator 8, the spring 10 of which provides continuous uniform compression, not depending on the shape of the bottle.

Guaranteed pressing of the smoothing plate 2 to the label glued to the surface of the bottle is carried out due to the fact that the upper 3 and lower 4 levers rigidly connected to each other by the clamp 6 and rigidly connected to the vertical threaded rod on which the smoothing plate 2 is attached form a single design having the ability to rotate relative to the place of articulation of the levers 3 and 4 to the element of the labeling machine under the influence of the rod 11 of the pressure controller 8.

Further, due to the movement of the bottle and the movement of the tape when winding onto the take-up reel, the label completely leaves the label removal plate, freed from the tape, and adheres to the bottle due to constant uniform pressing and smoothing by the smoothing plate 2. Next, the steps are repeated for the next bottle.

The combination of a rigid, predominantly metal, smoothing plate 2 with a regulator 8, which ensures that the smoothing plate 2 is constantly pressed against the surface of the bottle, allows labels to be glued onto bottles of various shapes, for example, having a cross-sectional shape that is close to rectangular, with no sticking defects (air bubbles under the label) arise.
