"COMPACT CUTTING STATION AND LAMI NATION OF FINE SELF-LABELING MANUFACTURING EQUIPMENT"

110011 INTRODUCTION - The present descriptive report relates to a patent application for cutting and rolling station, which belongs to the field of media used in the manufacture of labels and thin self-adhesive labels and was developed to perform the process of obtaining labels. thin self-adhesive objects covered by patent application PI 0805032-0 by the same applicant.

[002] STATE OF THE ART - Self-adhesive labels are known, formed by: body of label that has imprinted the label itself; per layer of pressure sensitive adhesive provided on one side of the label body. This label is originally supplied on label tape formed by: support and protection (liner) tape; and by a succession of labels glued to the release surface of the liner. Mentioned ribbon of labels, consisting of the labels and liner, forming a coil.

[003] The above-mentioned patent application states that, currently, a particularly desirable feature in certain self-adhesive label applications is transparency, which provides the effect that the constituent art of the label itself is printed directly on the packaging. To optimize this feat and in order to lower costs, thinner plastic films have been used.

[004] The thin films used usually meet the need, but when cut to define the label contours, it may be that, due to some slight mismatch in As the film is thin and thin, the cut also hits the liner, rendering the label tape being produced unusable.

[005] The manufacturing process disclosed in the above mentioned patent application aims to overcome this problem.

To this end, the process is essentially comprised of the steps of:

[007] 1) - Unwind the first clear thin plastic film reel, which will be the labels and the second silicon thin plastic film reel, which will form the liner in its own unwind, provided at the entrance of a continuous type manufacturing machine ;

2) - Print a succession of labels themselves on one side of the first thin transparent plastic film tape;

[009] 3) - Cut the first printed thin transparent plastic tape around the contours of the labels themselves with a perforation knife to form perforated cut lines around the label impressions and keep them attached to the plastic film tape. ;

[010] 4) - Apply adhesive to the silicon face of the second thin silicon plastic film tape;

5) - Laminating the first and second adhesive cut and siliconized printed thin transparent plastic film tapes, forming a laminated tape, composed of the first printed and perforated thin transparent plastic film tape and the second adhesive siliconized thin plastic film tape ;

6) - Extract the regions of the first thin transparent plastic film tape around the labels (skeleton) to form a tape composed of the liner and a succession of labels glued to the liner release (silicon) surface; and

[013] 7) - Reel the thin label tape into a thin label tape reel.

[014] In this process, the time between cutting the first ribbon that has the labels printed and its lamination on the second ribbon (liner) is critical due to the tendency of the first constitutive regions of the labels to have their contours cut, may adhere to the knife and be torn or shifted from the tape before it is laminated to the second tape (liner). This impairs the lamination and consequently the process.

OBJECTS OF THE INVENTION Thus, the purpose of the present invention is to provide a cutting and rolling station which performs the process according to PI 0805032-0 and which provides firm stability of the tape through all processes performed at the station.

[016] Another objective is to provide a simple construction, manufacturing and operating station.

[017] Another objective is to provide a low cost station for construction, manufacture and operation.

In view of the above problem and in order to overcome it and in order to meet the related objectives, the compact cutting and rolling station for thin self-adhesive labeling equipment, object of the present invention, was developed. patent, which is essentially comprised in sequence: by station-entry rubber cylinder; per pair of cutting cylinders comprising cylinder knife and counter knife; and by rubber rolling cylinder, this, the knife cylinder and the inlet cylinder are tangent to three points in sequence of the counter-knife. The thin film printed with the labels is received at the station by the inlet and stabilization cylinder; passes between it and the counter-knife cylinder; passes between it and the knife cylinder, where the contours of the labels are cut, without extraction of the skeleton; and passes between the counter-knife and lamination cylinder, where said printed and cut thin film and the pre-adhesive liner are laminated. Eventually, at the cutting station, consisting of the knife cylinder and counter-knife cylinder, a device may be provided that favors the non-adherence or expulsion of the printed thin film cut from the knife, said device may consist of providing the mattress knife cylinder of rubber which helps to expel the cut film onto the counter-knife, vacuum device provided in the latter, device comprised by applying static to the film or the counter-knife or others.

[019] The compactness of the station and the presence of the rubber inlet and stabilization cylinder allow the printed thin film to be received and advance within the firmly stable station, especially after cutting and between it and lamination, to prevent The labels, after having their contours cut, separate from the tape, thus preventing the process from being harmed, thus meeting the main purpose of the invention. In fact, the compactness of the station determines relatively short paths for the thin film tape within it, which favors that the stabilization provided by the inlet cylinder and rubber stabilization does not lose effect along this path.

[020] The compactness of this station makes it easy to install on label manufacturing equipment. [021] The station with the present solution, in addition to overcoming the state of the art problem, has simple, low cost construction, fabrication and operation, meeting other objectives of the invention.

DETAILED DESCRIPTION BASED ON DRAWINGS - The compact cutting and rolling station 1 (Figs. 2 to 7), object of this patent, is intended for use in manufacturing equipment Self-Adhesive Labels 100 (Fig. 1), which manufactures in accordance with the process object of the same patent application PI 0805052-0, substantially comprised of a succession of stations carrying out the manufacturing steps, namely:

[028] 1) - Unwinding in their own unwinders: first reel of thin transparent plastic film 200, which will form the labels and second reel of siliconized thin plastic film 300, which will constitute the support and protection tape (liner) of labels;

[029] 2) - Print a succession of actual labels 201 on one side of ribbon 200, forming a ribbon with a succession of printed labels 200-201;

[030] 3) - Cut the contours of labels 201 on ribbon 200 without detaching them, forming a ribbon 200'-201 '-202 composed of a succession of printed and contoured labels 201' and region (skeleton) 202 external to labels;

[031] 4) - Apply adhesive layer 301 to the release (siliconated) face of tape 300, forming adhesive liner tape 300-301;

5) - Laminating the tapes 200'-201 '-202 and 300-301, forming a laminated tape 200'-201' -202-300-301, consisting of: tape 200 'having labels 201' printed, with cut and not highlighted contours and skeleton 202; adhesive layer 301; and liner tape 300;

6) - Extract the skeleton 202, forming a ribbon of thin labels 201 -301 -300, composed by: the liner 300; by a succession of labels 201; and by layers of adhesive bonding 301 of labels 201 on the release (silicon) surface of liner 300; and

7) Winding and forming a bobbin 400 of the thin label tape 201 -301 -300. Optionally, manufacturing equipment 100 uses pre-printed label ribbon on out-of-line equipment. In this case, said manufacturing equipment 100 does not provide printing station (2) and its unwinding station (1) unwinds a ribbon 200 already printed with labels 201. This is the equipment / process as disclosed in the same applicant's patent application PI 0805052-0.

The compact cutting and rolling station 1, object of the present invention (Figs. 2) is used in this thin self-adhesive labeling equipment 100 described above. Said compact cutting and rolling station 1 is interspersed between the label printing station (2) 201 on ribbon 200 or already printed ribbon unwinder station (1) (when label ribbon is used in offline printing equipment) and the adhesive layer 301 station (4) on the liner tape (silicon) release surface 300, said station 1 incorporates: the label contour cutting station (3) and the lamination station (5) .

Thus, the compact slitting and rolling station 1 is formed essentially in sequence (fig. 3): by rubber inlet roll 10 and stabilizing tape 200-201 at station 1; per cylinder knife 20; and by rubber rolling cylinder 30 which are around and tangent to a counter-knife cylinder 21. Inlet rubber cylinder 10 and counter-knife cylinder 21 are tangent at first tangency point 40; the knife cylinder 20 and the knife counter 21 are tangent to the second tangent point constituting the label contour cutting station 201; and lamination rollers 30 and counter-knife roll 21 are tangent in a third constituent tangent point of the rolling station (5); said cylinders 10, 20, 21, 30 are supported by usual support and adjustment devices such as bearings, regulated supports and others and subjected to drive means (not shown), mounted on a frame (not shown) that rests on suitable surfaces. of the equipment 100.

[038] The inlet rubber cylinder 10 inlets the superfine film tape 200 printed with the labels 201 into the station 1 inlet and provides a first path run 50 for the printed label tape 200-201 between the inlet. of station 1 and the first tangential point 40 with counter-knife 21.

[039] From the first point of tangency 40 between said inlet rubber cylinder 10 and the counter-knife cylinder 21 and the point of tangency between the latter and the knife cylinder 20 constituting the cutting station (3) , on the surface of the counter-knife 21, a second path portion 51 is defined for the ribbon printed with labels 200-201.

[040] The point of tangency between the knife-cylinder 20 and the knife-counter 21 constitutes a cutting station (3), in which the tape printed with labels 200-201 is cut to the edges without being extracted. forming ribbon 200'-201 '-202 formed by ribbon 200' having labels 201 'printed with cut outlines and skeleton 202 around the labels. Cylinder knife 20 has several closed ring cutting knives 22 incorporated around its perimeter that cut the contours of labels 201 printed on thin film tape 200. [041] The surface portion of the counter-knife 21 between the cutting station (3) and the rolling station (5) constitutes a third path portion 52 for the cut-edge printed label tape 200 '-201' -202.

The point of tangency between the counter-knife 21 and lamination cylinder 30 constitutes the lamination station (5), on which said cut-off printed label tape 200'-201 '- 202 and the tape 300-301 adhesive liners are laminated, forming a 200'-201 '-202- 300-301 tape consisting of: 200 tape with cut and contoured 201' labels and skeleton 202 and 300-301 adhesive liner tape.

[043] From the rolling station (5) to the exit from station 1 a fourth stretch of path 53 is formed for the tape 200'-201 '-202- 300- 301 formed at station 1. This tape 200'-201 '-202- 300-301 goes to skeleton extraction station 6 (Fig. 2) which is part of manufacturing equipment 100.

Thus, the present station 1 performs the cutting and rolling operations efficiently, within the process as disclosed in the same applicant's patent application PI 0805052-0, due to its geometry - consisting basically of inlet and stabilization cylinder 10, knife-cylinder 20 and lamination cylinder 30 arranged around and tangent to the knife-counter cylinder 21 - result in a relatively short path for film tape 200 during processing, making it easier to stretch and not to loosen, especially by inlet cylinder action and stabilization 10. Thus, this tape is stable during the cutting operation favoring that there is no eventual detachment of the labels when cutting their contours.

[045] The compactness of station 1 further facilitates its installation on manufacturing equipment 100.

[046] Within the basic construction described above, it is claimed that the compact cutting and rolling station 1, object of the present patent, and the products obtained with it may present modifications regarding materials, dimensions, configurations, sequences of procedural steps. without departing from the scope of patent protection.

[047] Within this, the cutting station (3) may provide a device for better stabilization of the film tape 200 during its passage and cutting, avoiding the eventual extraction of part of the whole label 201 during the cutting of its contours.

[048] In one embodiment, said stabilizing device (fig. 4) is of the type comprised of a flexible rubber-like mattress 60 mounted on the surface of the knife cylinder 20 containing the knives 22 so that they cut the blade. 200-201 film and flexible mattress 60 compresses the cut film 200-201 against the counter-knife 21, preventing unwanted movement of the film from damaging the cut as well as favoring the expulsion of the cut film 200-201 onto the cylinder. knife finder 21.

[049] In another embodiment (fig. 5) there may be provided vacuum stabilizing device 70 consisting of the counter-knife cylinder 21 having a surface with suction holes 71 and being connected to a vacuum source 72 so that the film 200-201 is sucked against the surface of the counter-knife 21 thus becoming stable during the cut-off of the label-contour 201 made by the knife-cylinder 20

[050] In another embodiment, a static stabilizing device may be provided. In this case, in one embodiment a device 80 can be provided which provides static treatment on the film 200-201 (fig.6) upstream of the cutting station (3) so that it adheres to the surface of the counter-cylinder. Knife 21. Optionally, the stabilizing device consists (fig. 7) of the counter-knife cylinder 21 provided with a stably treated surface 90, which favors the adherence of film 200-201 thereon.

[051] The material to be processed at the compact slitting and rolling station 1 may be a thin film tape 200 having labels printed 201 to obtain a thin film label tape 200-201 as described above. Optionally, however, the material to be processed may be thin film tape 200 or other unprinted material from which blank labels 201 are obtained for variable data printing, such as product expiration dates, barcodes and others, thus obtaining a blank label tape 200-201. In this case, the compact slitting and rolling station 1 is immediately following a unwinder of a blank material spool.

[052] Station 1 is designed to process BOPP, PVC, PE, PET or other 10 to 60 micron thick polymeric films to obtain thin labels; said films may be transparent as described above or white or metallized.

[053] Optionally, station 1 can process paper tape to form the label front. [054] Station 1 processes 12 micron thick films, preferably PET, silicon BOPP or other 6 to 30 micron thick polymeric films, for liner formation.

[055] Process rubber-based or acrylic-based pressure-sensitive adhesive as provided in the same applicant's patent application process PI 0805052-0.
