Abstract

Stamping system for photo-digitalized monitoring has as its object an innovative cutting process by stamping, included in the electromechanical field, used for cutting around thin objects embedded between two polymeric films, since it innovatively comprises a process in which the transponders (1) are transported until the plastifier-cutter, being plastified between two polymeric pellicles, thus forming a double film pellicle (15) which follows until the locator-cutter device, which has the principle of transponder (1) localization on the double film pellicle (15) and its corresponding cuttings by stamping by means of the plastifier-cutter, by analysing the image of the contours of the transponder (1) to be cut, when it gets close to the vision field (22) of the digital video camera (20), so to direct it until the center of the stamping cylinder body (18), which is immediately activated by means of the pneumatic piston (17), cutting the plastified transponder (1A) over the support table (23) and subsequently ejecting it by means of the ejecting device (19), both computer (21) commanded.

Description

STAMPING SYSTEM FOR PHOTO-DIGITALIZED MONITORING has the object of an innovative cutting process by stamping directed by means of digitalized image analysis, included in the electromechanical field, used for cutting around thin objects embedded between two polymeric films, separating them from the original tape, to which original disposition was given, since it aims to enhance the production system over other systems traditionally in use in the field.

We therefore have a process which has been especially projected and developed to reach huge practicality and optimization, besides offering huge quality and quickness to the step of cutting transponders, plastified objects by the process of adhesive pellicle, a cutting process which has been developed from intellectual studies on the issue much besides the traditional experience existing in the field in which it is employed, in processes connected to the activity to which it is intended. It is also an object of the invention to present an innovative procedure disposition under low costs for industrial execution, but added to the requirements of safety, economy and utility practicality, thus offering users of said technical field an additional option in the market of similar products which, as opposed to the usual application of available processes, offers numerous possibilities of automation, being therefore largely accepted by the consumer market.

As known in the technical field, various industrial process steps must be performed by human handwork, mainly activities depending on unforeseeable decisions, i. e. activities consuming the sensorial acuity of men, a faculty to perceive a specific mode of feelings, such as heat, sound waves, flavor, corresponding to a given organ, which stimulation starts the internal sensorial reception process, being generally known touch, vision, audition, taste and smell.

Numerous examples can be mentioned, which in most cases are unforeseeable, due to the nature of the step to be performed, among them we highlight: smelling, for the automatic classification for formulation of perfumery products and coiffeur and aesthetics articles in the cosmetic industry; tasting, to distinguish and select among essences, flavors and corresponding mixes in the food industry; vision and touch, for the tridimensional instantaneous perception in the execution of activities requiring maximum sensibility, such as dental obturations and heart and neural surgeries in medicine.

Concerning activities depending on vision and touch, linked to unforeseeable strategic decisions, there are many efforts in the technological development to substitute human handwork, mainly in dangerous activities or excessively repetitive jobs, which expose human beings to work conditions causing health damage.

Cuttings between ornaments or stamped or randomly embedded dispositions in plastic pellicles, papers or textiles are activities intensively involving manual activities, with the direction of the cutting-stamping tool made as a function of the sensibility of the operator, as a function which could difficulty be performed by a mechanical equipment.

Aiming to offer the market an automated production process performing the cut of transponders, after embedding them between two adhesive plastic films, the present stamping cutting process directed by means of digitalized image analysis was developed, provided with features to locate and cut the transponder, which locator and cutter results in a process granting considerable precision, not damaging the plastified component. Therefore, the present patent application was created so to obtain the registration of a process with the least possible number of steps, conveniently distributed to allow manufactured plastified transponders to be automatically located and cut, saving manual handwork from inconvenient and extremely repetitive jobs, besides executing the substitution efficiently and precisely, optimizing time and displacing previously used handwork to more important activities.

The configuration of the device object of this patent, which in its new constructive shape comprises a process in which transponders prepared to receive plastifying pellicles are transported until the plastifier- cutter, being plastified between two pellicles by means of hot calendering, remaining included between both pellicles, forming a double-film pellicle, which remains tractioned by a reel until the locating-cutting device, constituted by a suspended platform, under which a pneumatic piston with a coupled stamping cylinder body, next to the double film pellicle, internally provided with an ejecting device, having on its side a digital video camera, connected to an appropriate computer, centrally positioned over the stamping cylinder body, locating-cutting device having as its transponder locating principle on the double film pellicle and its corresponding cuttings by stamping by the plastifier-cutter, by means of analysis of the image of the contours of the transponder to be cut, when it is near the vision field of the digital video camera, so that it can receive the image of the transponder and send it to the computer which, by analysing the image of the transponder contours by appropriate software, sends a signal to the directing device of the crosswise displacement bench, displacing it crosswise by a distance synchronously with the speed of movement of the double film pellicle, until positioning the transponder exactly in the middle point of the stamping cylinder body, which is immediately activated by the pneumatic piston, thus cutting the plastified transponder over the support table and subsequently ejecting it by means of the ejecting device, both computer-commanded.

We can therefore realize that the process at issue is extremely simple over employed machines, being therefore easily feasible, but excellent practical and functional results are obtained.

Projected to offer perfect finishing and the least number of manual interventions, it results in a product offering to the observer the same quality over the previous one or even enhanced.

Subsequently, for better understanding and realization of what constitutes the STAMPING SYSTEM FOR PHOTO-DIGITALIZED MONITORING as claimed herein, we present the attached illustrative figures, in which we can see:

Fig. 1 shows a schematic front view of the process. Fig. 2 shows a schematic front view of the process, detailing the locating-cutting device and its components.

Fig. 3 shows an upper schematic view of the process. Fig. 4 shows an upper schematic view of the process, detailing the locating-cutting device and its components.

According to what is shown by the above listed figures, the STAMPING SYSTEM FOR PHOTO-DIGITALIZED MONITORING, object of this application, is constituted by a process in which transponders (1), prepared to receive plastifying pellicles, are transported to the plastifier- cutter (2), constituted by a crosswise displacement bench (3), supported by means of pulleys (4) over guide rails (5) supported by a rectangular base (6), being said crosswise displacement bench (3) moved crosswise by a directing device (7). Over the crosswise displacement bench (3), the plastifying device is supported, constituted by a lower polymeric pellicle (8) originated from a coil (9) supported over a tensioning rack (10), lower polymeric pellicle (10) over which transponders (1) are randomly located and prepared to be plastified by means of the upper polymeric pellicle (11 ), originating from a coil (12), supported over a tensioning rack (13), upper polymeric pellicle (11 ), which is linked to the lower polymeric pellicle (8) containing the transponders (1) by means of hot calendering through the calender (14), being included between both pellicles, forming a double film pellicle (15), which remains tractioned by a reel until the locating-cutting device, constituted by a suspended platform (16), under which a pneumatic piston (17) having a stamping cylinder body (18) coupled to it, next to the double film pellicle (15), internally provided with an ejecting device (18), having at its side a digital video camera (20) connected to an appropriate computer (21 ), in central position towards the stamping cylinder body. The localization principle of transponders (1 ) in the double film pellicle (15) and their corresponding stamping cuttings by means of the plastifier-cutter occurs when the transponder (1 ), linearly or randomly positioned inside the double film pellicle (15) gets close to the vision field (22) of the digital video camera (20), so that it can receive the image of the transponder (1A) and send it to the computer (21 ) which, by analysing the image of the contours of the transponder (1A) by appropriate software, sends a signal to the directing device (7) of the crosswise displacement bench (3), displacing it crosswise through a distance (A) synchronously with the speed of movement of the double film pellicle (15) until positioning the transponder (1A) exactly in the central point of the stamping cylinder body (18), which is immediately activated by means of the pneumatic piston (17), thus cutting the plastified transponder (1A) over the support table (23) and subsequently ejecting it by means of the ejecting device (19), both computer (21 ) commanded. We therefore conclude from the above explained that the

STAMPING SYSTEM FOR PHOTO-DIGITALIZED MONITORING at issue is a largely useful product, presenting all practical and functional qualities plainly justifying the application for a Patent and Invention Privilege. Although the present application has been illustrated and described with reference to the above intended mode, it will be evident to the experts in the art that other changes in composition and process details may be effected herein, not leaving the spirit and scope of the application, as well defined in the attached claims.
