    [0001] Automatic adhesive tape applicator
    [0002]
    [0003] The present specification refers, as its title indicates, to an adhesive tape applicator of the type used industrially for the automatic application of single or double-sided adhesive tape. A quasi-machine is treated, as defined in the European Machinery Directive 2006/42 / EC, which can be associated with a robot of any type or other mobile support driven by an electromechanical system or by human action. It is characterized in that it comprises an electrically actuated clutch assembly from a potentiometer related to a belt tension probe, and an electrically operated belt thermal cutting mechanism.
    [0004]
    [0005] Field of the Invention
    [0006] The invention relates to the field of double-sided adhesive tape applicator devices for automated use.
    [0007]
    [0008] Current state of the art
    [0009] For the union of different surfaces in the industrial environment, it is very common to use adhesives of different types, in liquid or semi-liquid format, easily automatable, but that present the problem of requiring large drying times other inconveniences of lack of precision and staining typical of its liquid character. This can be solved by using double-sided adhesive tape, wound on a plastic guide or "liner", which does not require drying times and does not flow from its application site.
    [0010] Currently, multiple devices for the application of double-sided adhesive tape are known. Most of them are designed for exclusively manual use, as we can find described in patents ES0233859 "A dispensing device for the expansion of continuous or discontinuous adhesive tape on both sides", ES2365279 "Portable adhesive applicator ' and ES0113786 " An applicator of adhesive tape ", and are very prone to breakage in the tape or to jams due to incorrect synchronization between supply and collection of the tape.
    [0011] There are also more sophisticated and precise industrial applicators, such as those claimed in patents ES2211825 "Adhesive application tool and procedure for an automated application of serial adhesive tape", ES1008594 "Tape applicator head in box sealing machines", US4270971 "Applicator for double-sided tape strips" and US4026754A "Apparatus for the application of double adhesive tape", but all of them present the problem of being fixed, heavy and bulky equipment, quite complex mechanically, and that for the application of the adhesive tape on an object they need this object to move and move in front of the machine applicator, which greatly limits its application in case of very bulky or heavy objects, complicating and making the process more expensive.
    [0012] Some of these applicators, such as the one described in patent US2003084987 "Adhesive applicator" can use mechanically regulated clutches for a regulation of the flow of tape, but they are inaccurate equipment, with too much weight for mobile operation, and which make their cost quite expensive.
    [0013] Some equipment is also known, such as that described in US2005081627 "System and method for dispensing correction weight of adhesive imbalances" that use complex electronic control feedback systems, external to the equipment, to regulate the flow of tape, with the problem of its great complexity and cost, in addition to requiring expensive equipment external to the applicator.
    [0014]
    [0015] Description of the invention
    [0016] To solve the current problem in the application of adhesive tape, especially for its automated use associated with robots or other mobile supports, improving the state of the art, the adhesive tape applicator object of the present invention has been devised, which comprises a support body, on which a load shaft and a rewind shaft are mechanically related to transmission gears located under a rear cover, driven by the movement of the double-sided adhesive tape itself.
    [0017] The device also consists of an application mechanism, an electrically operated belt cutting mechanism, and a tensioning probe, optionally comprising one or more auxiliary guides.
    [0018] The double-sided adhesive tape cartridge is located on the loading axis, by means of the appropriate coupling mechanism, and the collection cartridge of the excess plastic guide or “liner” is located on the rewind shaft, also by another coupling mechanism .
    [0019] The adhesive tape circulates from the loading axis, to the application mechanism, returning the remaining plastic guide through a sliding channel of said application mechanism, passing through a tensioning probe to the rewinding axis where it is collected. The tensioning probe activates an analog potentiometer depending on the tension of the plastic guide, thus regulating the electrical voltage supplied from a power source to an electric clutch located on the load axis, allowing control of the amount of adhesive tape to be unwound by the regulation of friction, and therefore of the force, that the electric clutch performs.
    [0020] The tape cutting mechanism performs heat cutting and is electrically operated.
    [0021] The applicator may also optionally comprise mechanical and electrical connection means with an external robot arm or with mobile supports driven by electromechanical systems.
    [0022]
    [0023] Advantages of the invention
    [0024] This applicator of adhesive tape that is presented provides multiple advantages over the equipment currently available, being the most important that thanks to the use of a combination of a probe, potentiometer and electric clutch, a perfect regulation of the tension of the tape and a Optimum flow, avoiding the mismatches that produce tape loops and jams due to lack of tension, or breakage due to excessive tension. Another important advantage is that thanks to this operation with friction regulation of the load shaft by means of the electric clutch, an operation without stops or breakdowns is achieved, in addition to a light and versatile equipment, promoting its automated use by robots of any type or by mobile stands It is important to highlight that this applicator, unlike the existing ones, is of the mobile type, that is, the object on which the adhesive tape is to be stuck remains static, while the applicator, moved by the robot or by mobile supports. It moves around it by applying the pressure tape where necessary. This allows its use with objects of any size and weight, avoiding the usual limitations in existing industrial wrapping machines.
    [0025] Another advantage to highlight is the incorporation of a heat cutting device, with electric drive, which also allows automated operation, supplying the necessary quantity and avoiding waste of tape.
    [0026] Another of the most important advantages to highlight is that the applicator is self-regulating, not needing external supply tape control mechanisms, just enough with the movement provided by the robot arm.
    [0027] We must not forget that this applicator device allows quick and easy accessibility to reels of tape, both loading and collection, accelerating and facilitating the change of material.
    [0028] Also another added advantage is that it is a device that allows its application to any type of robot, both anthropomorphic and gantry arm with both Cartesian axes and multi-axis parallel kinematics, as well as other types of mobile supports.
