    Label desmallador system. The conventional stripping systems incorporate a roller (9), from which the mesh (17) obtained in the die-cutting process is separated from the sheet of siliconized or waxed paper (15) carrying the labels (14), in such a way that that the mesh (17) is wound in a shrinkage collection coil (11) and the siliconized or waxed paper sheet (15) carrying the labels (14) is wrapped in a final collection coil (16), complementing the roller (9) with a support roller (10) tangential to said roller (9), essential when carrying out the winding of meshes of irregular configuration, but which nevertheless at the time of winding regular meshes suppose a element that slows down this process. The invention consists in that the axis (12) of rotation of said roller is associated with a linkage/uncoupling mechanism of the drive transmission thereof, such as a clutch system or the like that allows releasing said roller to accelerate the winding process when the mesh is regular, or use said roller to apply a suitable torque on the mesh in order that it does not break in the winding process when it is irregular. Additionally, the system is capable of including a second support roller (19) tangential to the support roller (10), either free-standing or static, in the latter case provided with air injection means.

    LABELING SYSTEM OF LABELS

    D E S C R I P C I Ó N
    OBJECT OF THE INVENTION 5

    The present invention relates to a label desmelling system, the purpose of which is to eliminate the leftovers of a label roll after its die-cutting process, so that the label roll finally obtained contains only the labels arranged on the paper roll paraffin or silicone, in order to facilitate its subsequent detachment.

    The object of the invention is to provide the labeling sector with a system by which the process of desmallado of both regular and irregular configuration labels is optimized, avoiding mesh breakage and optimizing the working speed. fifteen
    BACKGROUND OF THE INVENTION

    In the practical scope of the invention, that of the adhesive labels, in order to facilitate their removal in the final labeling process, they are supplied with their final configuration on a roll of paraffinized paper or siliconized support. from the same.

    However, to get to this configuration, it starts from an initial bi-layer coil, in which the adhesive paper from which the labels are to be obtained has the same width as the sheet of paraffin or siliconized paper on which it is adhered, so that said paper is passed through a printing unit, to later pass through a stamping station in which the intended final shape for the labels is given, keeping the base sheet of paraffinized or siliconized paper its with -30 figuration, so that the edges or "remains" of the adhesive paper are continuously detached from the treated reel through a module of desmallado, while the desmallado product is rewound for final distribution.

    The collection and winding of the aforementioned "remains", known in the sector as "mesh", depends on the configuration of the labels, so that if they present a regular configuration, whether rectangular, circular, or similar, the winding process, both of the coil of the final product, and of the coil with the shrinkage or mesh, can be done at a much higher rate than if the labels have an irregular or complex configuration, in which If such a process must be carried out at a lower speed, the use of additional rollers is necessary to avoid breaking the mesh.

    As in most cases it is not economically feasible to have a rack of facilities for two types of labels referred to above, the reality is that what is done is to opt for the most complex solution, that is, the one designed for irregular configuration labels, which although it is perfectly valid for the treatment of regular configuration label reels, the reality is that they slow down the process when it comes to winding said regular configuration labels. fifteen
    DESCRIPTION OF THE INVENTION

    The label desmallador system that is recommended solves in a completely satisfactory way the problem previously exposed, allowing to optimize the process of desmallado at all times, depending on the configuration of the labels to obtain.

    To do this, and more specifically, based on the conventional structuring of this type of installation, in which it starts from an initial reel, which feeds one or more units of serial printing, so that said reel once properly The dam is impelled through a die-cutting station and the exit of this one to a proper desmallator system, in which the external mesh or die is separated from the label-bearing band by means of a main coil and tractor unit that redirects on the one hand the stripped label band towards a final coil, and the mesh or overhang of the die cut towards a collection coil whose axis of rotation is horizontally movable, in order to adopt different positions and angles in function of the diameter that said coil acquires, a set that is complemented by a support roller, tangential to the tractor roller, and which facilitates the addressing of the detached mesh band, especially in that The cases in which the dies / mesh have a
    irregular configuration.

    Also, as is conventional, the rollers and coils will be assisted by servomotors by means of which to adjust the speed of rotation according to the specific needs of each case. 5

    Well, from this structuring, the essence of the invention is centered on the fact that the support roller, fundamental for the winding of irregular meshes, and nevertheless a slowing element of the winding process of regular meshes, presents in correspondence with its axis of rotation, practicable disengagement means of the transmission associated therewith, such as a clutch system or the like, from which, when it comes to carrying out the dismantling of regular configuration labels, said The shaft will be disengaged, turning insane, allowing the winding process to be accelerated by electronic control of the rest of the servomotors associated with the different cylinders / coils. fifteen

    Optionally, the system could include an additional cylinder in order to shorten the critical area of breakage, tangent to the support roller, which may rotate freely or simply be a static roller but with air injection means, to act as a guide and support in the process of desmallado, shortening the critical zone of breakage as it has been commented 20 previously.

    From this structuring, the system allows complex materials and forms to be worked, difficult to remove, avoiding mesh breakage and optimizing the work speed, being controlled by servomotors that allow varying the speed, the motor torque, 25 accelerations and decelerations very precisely, defining a fully autonomous system of the machine where it will be installed.
    DESCRIPTION OF THE DRAWINGS

    Figure 3.- Shows, finally, a view similar to that of Figure 2, but in which the system includes an additional roller that shortens the critical area of breakage.
    PREFERRED EMBODIMENT OF THE INVENTION
     fifteen
    In view of the aforementioned figures, it can be seen how the desmelling system of the invention is intended to be implanted as an independent module (1) in an installation (2) for obtaining adhesive labels, in which an initial coil (3) participates. ) of a bilayer nature, in which a sheet of adhesive paper arranged on a sheet of paraffin or siliconized paper participates, both layers having the same width initially.

    Said initial coil (3) through a series of routers (4) is made, in this case, by a series of printing units (5) responsible for obtaining the screen printing of each label to be obtained, so that at the exit of said printing zone (6) the continuous sheet is passed through a stamping station (7), which in turn feeds the module or system of desmallado (1) through a series of guide rollers (8).

    Obviously the resulting object can pass this stage without printing, when the design 30 justifies it.

    In said desmallado module a main roller (9) is established, from which the mesh (17) is separated from the sheet of siliconized or paraffined paper (15) carrying the
    labels (14), as shown in Figure 2, so that, in order to avoid the breakage of said mesh (17), especially in cases where the perimeter of the label is not regular, said roller (9) is complemented with a support roller (10) tangential to the roller (9) and whose axis of rotation (12) is also associated with a motor-reducer group in which the corresponding servo motor participates, being redirected by On one side the mesh (17) towards 5 a shrinkage pickup coil (11), whose axis of rotation (13) is horizontally movable to adapt different positions and angles depending on the size that the coil acquires during its winding, coil that is also assisted by a servo motor with adjustable speed, so as to ensure constant speeds and tensions during said operation, achieving a more reliable production. For its part, the continuous sheet of siliconized or paraffined paper (15) carrying the labels (14) devoid of the remains of the die cut is redirected through a series of rollers (18) towards a final collection coil (16).

    Well, according to the essence of the invention, it is provided that the axis of rotation 15 (12) of the support roller (10) is associated with a linkage / disconnection mechanism of the drive transmission of said roller , such as a clutch system or the like, which allows the appropriate traction torque to be applied when the mesh to be collected has certain irregularities, as well as detaching said axis from the motor system, in order to leave the roller rotating freely, without opposing resistance or exerting any kind of force on the mesh, in order to accelerate the winding process when the meshes have a regular configuration.

    Optionally, and according to Figure 3, additionally, the system could include a second support roller (19) tangential to the support roller (10) and ra-25 dial movement with respect to the axis (12), to be adapted in the ideal position according to the variable diameter of the collection cylinder (11), in order to shorten the critical break zone; This cylinder (19) can rotate freely or simply be a static roller but with air injection means, acting as a guide and support for the set of sheets (15-17) defining from this point the detachment between both sheets, shortening the critical break zone by 30.

    Between the cylinders (9) and (19), other cylinders of the same characteristics of the cylinder (19) could be located, in order to hold the carrier sheet of the labels to
    desmallar.

    All the system component cylinders, such as the roller (10), can be of variable diameter, and of suitable characteristics depending on the deflation objective to be performed, as for example they can be drilled in their contact surface 5 with the band of labels, for the passage of compressed air either one way or another.
