    Method for producing a stamp impression with UV-curable ink with a preferably self-inking stamp and stamp therefor
    The invention relates to a method for producing a stamp impression with UV-curable ink with a preferably self-inking stamp and a stamp as described in the preambles of claims 1, 14 and 16.
    From AT 009 206 U a stamp is known in which to increase the
    Forgery-proof use is made of an ink pad mixed with color, one or more different colors being provided, at least one UV color or at least one of the colors containing UV color particles which are only visible when irradiated with UV light.
    The disadvantage here is that the stamp imprint can be easily blurred on difficult surfaces such as glass, metal, aluminum, cardboard, etc.
    In order to avoid the blurring of a stamp imprint, DE 7601070 U discloses a device for curing the stamp color of a stamp imprint on an object or workpiece, in which a guide rail for receiving the lamp or workpiece to be irradiated is provided in a housing with perforated base plates and cover plates is arranged, a metal halide lamp with a high UV component being arranged as a UV radiation source at a distance of approximately 30 mm from the printing on the lamp.
    The disadvantage here is that the object or the workpiece, in particular the lamp to be irradiated, must first be stamped, after which it can be inserted into the device for drying. However, there is a risk that the stamp imprint will be blurred when it is inserted. Also, only smaller objects can be placed in such a device.
    The object of the invention is to provide a method for generating a
    To create stamp imprints with UV-curable ink with a preferably self-inking stamp and a stamp, in which the above-mentioned disadvantages are eliminated and a quick drying of a stamp impression on most surfaces and with any size of the workpiece is possible.

    The object is achieved by the invention.
    The object of the invention is achieved by a method for producing a stamp impression with curable ink with a preferably self-inking stamp, in which a control is activated, wherein at least one or more radiation sources arranged on the stamp and with UV-rays directed towards an impression surface are used to harden the ink. Blasting is turned on.
    It is advantageous here that the use of additional components for curing the ink ensures that blurring of the stamp impression is avoided. This is particularly advantageous if a color with a very long curing time is used, the curing time being able to be significantly reduced by using certain radiation options, such as UV rays in particular. Another significant advantage is that in the stamp according to the invention all the components required for this, such as radiation source, control and energy source, are integrated in the stamp, so that the user does not need and need to operate any other additional devices. The usual stamp sequence is not changed by simply compressing the stamp, so that very easy handling is achieved.
    The measures in which the control is activated before or during the stamping process are particularly advantageous, the control being activated during or immediately after the stamping process, at least one or more radiation sources on the stamp, in particular in the interior, oriented in the direction of an impression surface of the stamp Curing of the color activated, especially turns on. This ensures that the control is switched on at the same time by simply actuating the stamp, the stamp imprint is generated and cured via the radiation source, so that when the stamping process is finished, the user can remove the stamp, preferably without waiting, so that immediately afterwards via the generated one Stamp imprint can be wiped or scratched. This stamp, preferably with UV-curable ink, is preferably used on surfaces that are difficult to stamp, such as glass, metal, aluminum, cardboard, wood, etc., with the prior art using inks with a high solvent concentration, which evaporate after the stamping process, in addition to this however, a drying time of more than 5 to 10 seconds is required.
    3/43
    UV Light Temple
    The measures are advantageous in which the control is activated, in particular switched on, during the resetting of the text plate from the stamp position to the rest position, in particular shortly before reaching or when reaching the rest position, at least one or more radiation sources on the stamp. This ensures that a great deal of energy can be saved in the energy store, since the radiation source is only switched on in the final stage, that is to say after the stamp impression has been generated, and not at the start of the stamping process. Thus, the duration of use of such a stamp is significantly increased with your energy storage charging cycle.
    Also advantageous are the measures in which the impression unit and / or the text plate is designed such that in the rest position it covers or closes a pad of the stamp pad used, which is soaked with preferably UV-curable ink. This ensures that when activated in the return movement, the text plate shields the UV light from the ink pad, so that unwanted hardening of the ink in the ink pad is avoided, for example when using a self-inking stamp that can be swiveled through 180 °.
    The measures in which the radiation source is activated during or after the stamping process for a period of less than 2 seconds, preferably between 0.5 and 0.1 seconds, are advantageous. It is advantageous that a high
    Safety aspect for the protection of the eyes is guaranteed, since the switch-on time is very short, so that there can be no injuries to the eyes. It is also possible that when the stamp is lifted from the surface of the object, workpiece or document to be stamped while the light source is switched on, the control unit deactivates it immediately, i.e. that triggering is prevented when the stamp is lifted or the switched on light sources are switched off immediately be deactivated in order to avoid possible damage to the eyes of a user or another person nearby. This ensures that a high safety aspect for the protection of eyes is guaranteed.
    The measures are advantageous in which the control detects a position of the text plate or the upper part and the lower part relative to one another during the stamping process, the control and / or the radiation sources being activated in particular at certain detected positions. This ensures that exactly the
    4/43
    UV Light Temple
    Switch-on time for the radiation source can be determined, regardless of whether a user carries out a stamping process at slow or fast speed.
    At the same time, considerable energy is saved if the control is only activated at a certain position during the stamping process in order to achieve the longest possible runtime with a charging cycle.
    The measures in which the detection of the text plate or the upper part and the lower part with respect to one another are advantageous via an integrated sensor system, preferably capacitive capacitor plates or elements or via contact elements or magnetic switching elements. This enables or enables contactless detection and activation for the control and / or radiation source, so that the handling during the stamping process is not influenced. In addition, the switch-on time for the control and light sources can be changed variably since the activation can take place depending on the field strength.
    The measures in which the text plate has an advantage are advantageous
    Turning mechanism of 90 ° or preferably 180 ° is pivoted or rotated from the rest position into the stamp position, and that a stamp pad is used to hold the UV-UV-curable ink, against which the text plate rests in the rest position. This makes it possible to use a commercially available stamp, as shown in the exemplary embodiments below. At the same time, the use of so-called self-inking stamps, in which the color is absorbed by contacting the cushion of the stamp pad, has the great advantage that the impression unit or the text plate itself serves or can be used in shielding the radiation from the color in the stamp pad.
    But it is also advantageous to take measures in which one or more
    Radiation sources in the area of the impression surface of the stamp, in particular on a lower part of the stamp, and / or on the back of the text plate, in particular on the side of a text plate holder protruding towards the contact surface, and / or on the lower part, in particular the top of the interior, is attached or ., The light emission is aligned in the direction of the impression surface, in particular in the interior of the lower part of the stamp. This ensures that the UV rays of the radiation sources are always in the direction of the impression made on the surface of the
    5/43
    UV Light Temple
    Object or workpiece or document are emitted, so that this fully activates and cures the curing process when it hits the UV ink.
    The measures are advantageous in that, depending on the size of the text plate, the number of radiation sources used is defined, taking into account their technical data. This ensures that full coverage of the impression area is ensured with the most varied stamp sizes, since correspondingly more radiation sources are used for larger stamp areas. The radiation sources used, in particular LEDs, can also be taken into account, since less of these are required for stronger LEDs.
    The measures in which the control is deactivated after a stamping operation within a predeterminable time period or directly when the radiation sources go out are advantageous, with a new stamping process remaining activated within the time period for deactivating the control. This ensures that energy can be saved.
    However, the measures in which the stamp components, in particular the lower part, are designed as UV protection against the eyes are also advantageous, for this purpose a transparent viewing window or, in the case of transparent surfaces, these as UV-impermeable material, in particular made of polymethyl methacrylate or
    Polyallyl diglycol carbonate, etc. is used. The result of this is that the transparent design enables the stamp to be optimally positioned, but the eyes or the surroundings are protected from the emitted UV rays.
    In addition, the measures are advantageous in which the controller, the energy source and at least one or more radiation sources form a structural unit or module, in particular a retrofit module, which is attached to the impression unit, in particular on the opposite side of the text plate is stuck. It is thereby achieved that a standardized stamp can be equipped with such a module at any time or can be removed when it is not being used. The ink pad only has to be replaced when using such a module.

    UV Light Temple
    However, the object of the invention is also achieved by a method for producing a stamp impression with UV-curable ink, in which a control is activated, wherein after the stamp impression has been generated, the stamp or a
    Additional component of the stamp, in particular a closure cap, with light sources arranged thereon, is manually aligned for the stamp impression and the light sources are activated for irradiating the stamp impression.
    It is advantageous that in such a solution all components are in turn housed on the stamp or its accessories, so no additional devices are required, and the user only has to manually align the stamp or the additional components for printing in order to activate them by activating the light sources To bring hardening. In this way, it is advantageously achieved that stamps are also used in which the color memory can be shielded, as is the case, for example, with flash stamps, since this simply has to be turned sideways or so that the radiation from the radiation sources does not can get to the color memory. With stamps of this type with UV, UV-curable ink, it must be ensured that the rays do not get into the ink reservoir or ink pad, since otherwise the ink in the ink pad or ink reservoir itself will be hardened and thus the ink pad or the color memory is unusable.
    However, the measures in which the radiation source is activated over a period of less than 2 seconds, preferably between 0.5 and 0.1 seconds, are also advantageous. The result of this is that a very short dwell time or alignment is necessary and the risk of the stamp imprint being blurred is reduced.
    Furthermore, the object of the invention is also achieved by a stamp, in which a control with an energy source connected thereto, in particular a rechargeable button cell or rechargeable battery, is arranged in or on the stamp component, which is arranged via lines with at least one or more on the stamp component Radiation sources is connected.
    It is advantageous here that the line connection between the control and the light source on the stamp enables it to be easily activated for curing the stamp impression. Activation is possible before or during or after the stamping process. It is also possible for the activation to be carried out manually, for example using a button, and the control unit corresponds to the required time period
    7/43
    UV light stamp fully hardened the color of the light source activated. In the case of an automatic process, the control is preferably activated independently, so that it switches on or activates the radiation sources for a settable period of time in a certain detected position of the text plate, in particular after the stamp impression has been generated.
    The designs in which the radiation sources are arranged in such a way that their UV rays are oriented in the direction of an impression surface or the stamp impression produced are advantageous. This ensures that in the stamp position, the curing process takes place simultaneously via the rays of the light sources. The result of this is that the stamp impression is simultaneously generated in one work process and the curing process is carried out without changing the position of the stamp. By appropriate dimensioning and optimized arrangement of the radiation sources, the curing processes, i.e. switching on the light sources, can be carried out to less than 2 seconds, in particular between 0.5 and 0.1 seconds, so that no dwell time after the stamping process is necessary.
    An embodiment is also advantageous in which the radiation sources on the stamp are preferably arranged on the upper part or on the side surfaces for manual alignment with the impression surface. It is thereby achieved that other types of stamps, such as flash stamps, in which the printing unit cannot protect the color from the rays, can also be used, since in the case of such stamps the stamp impression is first generated, and then the stamp is turned to that side , on which the light sources are arranged and this is placed or held over the stamp imprint, whereupon the light sources are activated so that the stamp imprint is cured by the emitted rays.
    An embodiment in which the hardenable ink is arranged in an exchangeable ink pad, in particular in a soaked pillow, is advantageous, with the text plate for receiving the hardenable ink resting on the pillow when the ink pad is inserted. This ensures that new ink is always taken up after each stamping process and thus a high print quality is achieved. At the same time, the ink pad can be exchanged quickly when the ink is used up, so that the stamp can be used again quickly.
    8/43
    UV Light Temple
    An education is also advantageous, in which the text plate at one
    Stamping process for generating the stamp impression in the stamp position, the impression unit with the text plate can be adjusted from the rest position into the stamp position by about 180 “or 90 ° using a turning mechanism. It is thereby achieved that, due to the rotary movement, the impression unit simultaneously serves to generate the stamp impression and to shield it from the rays of the light sources against the stamp pad.
    However, an embodiment is also advantageous in which the energy source and the control are arranged on an upper side of the lower part, the radiation sources being attached to one or more surfaces of the lower part in the region of an imprint area or footprint, the radiation source or radiation sources are oriented in the direction of an interior, in particular the impression surface. It is thereby achieved that the components required for the curing are all bundled in one part, so that only in this part is there an increased production outlay.
    An embodiment is advantageous in which at least one or more radiation sources are arranged on the opposite side of the text plate, in particular on the printing unit or text plate holder, the control and the energy source likewise being arranged on the printing unit. It is thereby achieved that all electrical components are in turn arranged on one part, namely the impression unit, so that the production of only one part is more complex. At the same time, short cable connections can be achieved thanks to the compact design.
    However, the designs in which the individual components for curing the paint, in particular the radiation sources, the control system, the energy source etc., are arranged in a common housing to form a module, which can be exchangeably connected to the impression unit, are also advantageous. The result is that simple retrofitting or replacement is possible, so that a conventional stamp can easily be converted to a special stamp by attaching the module to the impression unit and using an appropriately colored stamp pad.
    However, an embodiment is also advantageous in which a transparent, exchangeable protective cover, which is preferably arranged, is arranged above the radiation source or sources
    9/43
    UV light stamp is simultaneously designed as a lens, in particular a diverging lens, for better distribution of the UV rays in the interior. This ensures that the radiation sources are easily protected, because if they become soiled with the UV-curable paint and if the light source is activated, the paint would harden immediately on the light source and therefore this can no longer be easily removed, so that the stamp is usually unusable would. If the protective cover is dirty, the protective cover can easily be replaced so that the stamp can continue to be used.
    An embodiment is also advantageous in which at least one or more radiation sources are arranged on the opposite side of the text plate, in particular on the impression unit or text plate holder, the control and the energy source being arranged on the upper part or lower part or also on the text plate holder. This ensures that there is sufficient space in the interior of the upper part to accommodate the components, so that additional functions that are difficult to accommodate in the lower part can be easily installed.
    Finally, an embodiment is also advantageous in which the radiation source is arranged in the upper part and / or lower part, with guide elements, in particular light guides and mirror systems, which deflect the emitted rays, in particular UV rays, in the direction of the impression surface, for irradiating the stamp impression. It is thereby achieved that the radiation source is positioned at the place where sufficient space is available, since the radiation source does not have to be arranged directly in the subject area to the imprint area due to the forwarding of the rays. Such indirect lighting or irradiation has the further advantage that it enables easy access to the radiation sources, since these can be reached at any time from the outside, for example, by means of a cap.
    It is pointed out that the advantages can be combined with one another, so that not all advantages have always been mentioned in order to avoid repeated repetition.
    The invention is subsequently described in the form of exemplary embodiments, it being pointed out that the invention is not limited to the exemplary embodiments and solutions illustrated and described.

    In the introduction, it should be noted that in the different embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, laterally, etc. related to the figure described and are to be transferred to the new position in the event of a change of position. Can too
    Individual features or combinations of features from the exemplary embodiments shown and described represent independent inventive solutions.
    1 to 3 show an exemplary embodiment of a stamp 1, in particular a control stamp, which, for example, as a stamp print 2 shows a QR print, personal characters, bar codes etc., preferably the stamp surface, in particular the size of the text plate, between 1cm x 1cm to 4cm x 4cm. Of course, it is also possible that smaller or larger stamp surfaces and also other shapes, such as rectangular, round, oval, triangular, etc., can be used. It is also possible that the designs in the individual exemplary embodiments in FIGS. 1 to 12 can be combined with one another or exchanged.
    The stamp 1 shown is a so-called self-inking stamp 1, in which a text plate 3 with the negative stamp impression 2 bears against a stamp pad 4, in particular a pad soaked with UV-curable ink 5, for receiving the ink 5.
    The stamp 1 is formed from stamp component 6 and an impression unit 7 with a text plate 3 attached, in particular glued, to it. The stamp component 6 consists at least of an upper part 8 and a lower part 9 with a cushion receiving element 10. The upper part 8 is designed like a cap and encloses the lower part 9, a spring element 11 being arranged between the upper part 8 and lower part 9, as shown schematically in broken lines, so that when the stamp 1 is actuated, the upper part 8 is pushed from a rest position 12 over the lower part 9 into a stamp position 13, as indicated schematically by broken lines, and then over the
    12/43
    UV Light Temple
    Spring element 11 is returned to the rest position 12, that is to say the stamp 1 is pressed together, so to speak, in order to produce a positive stamp impression 2.
    The impression unit 3 is connected to the upper part 8 by means of a turning mechanism 14 which is formed by 180 ° and is connected in motion in the lower part 9 via an axis 15 or axle journal 15, so that the impression unit 7, as is known from the prior art, is located in the lower part 9 of the Rest position 12, according to FIGS. 1 to 3 in full lines, can move into the printing or stamp position 13 (as indicated by dashed lines in FIGS. 2 and 3) by applying pressure. During a stamping process, the stamp 1 is placed on an object 16, documents 16, or workpiece 16, in particular with a smooth surface 16a that is difficult to stamp, over the impression surface 17 or contact surface 17a, which is preferably equipped with anti-slip devices 18, and a stamping process is carried out , so that the stamp imprint 2, as shown schematically, is generated on the object 16, documents 16, or workpiece 16.
    Since this stamp 1 is designed for surfaces which are difficult to stamp, such as glass, metal, in particular steel, aluminum, magnesium, plastics, etc., the stamp pad 4 is filled or impregnated with UV-curable ink 5, this ink 5 being UV- Rays 19 from at least one or more light sources 20, is activated and cured.
    The one or more radiation sources 20 are arranged in the stamp 1 such that their UV rays 19 are aligned in the direction of the impression surface 17 or the stamp impression 2 generated. In the exemplary embodiment shown in FIGS. 1 to 3, a total of six radiation sources 20 (see FIG. 3) are arranged, these being arranged in the lower part 9, in particular in the area of the contact surface 17a or impression surface 17, and in an interior 21 of the lower part 9 Activation light up. In order to increase the luminosity in the interior 21 or to direct the UV rays 19 in the direction of the stamp impression 2, it is possible for inner surfaces of the lower part 9 and / or the impression unit 7 to be provided with a reflection layer and / or reflection foil (not shown) , so that the UV rays 19 emitted by the radiation source 20 against the stamp impression 2 or impression surface 17 are reflected on these surfaces, so that the UV rays 19 incident on the stamp impression 2 are increased.
    However, in order that the radiation sources 20 can be activated, it is necessary for a corresponding control 22 or control electronics and energy source 23 in the stamp 1
    13/43
    UV light stamps are arranged, the individual components, in particular the radiation sources 20, control 22 and energy source 23, being connected to one another via lines which have not been shown since these are integrated in the parts of the stamp 1. For the sake of order, it is pointed out that the lines and other components can also be injected or embedded in an injection molding process during manufacture.
    According to the invention, it is thus possible for a stamp impression 2 to be produced from a UV-UV-curable ink 5 in a single work step, in particular a single stamping operation, and to be cured with UV rays 19 from radiation sources 20. Ie that to generate the stamp imprint 2 with UV-curable ink 5 with a preferably self-inking stamp 1, the text plate 3 with the negative stamp impression 2 is moved from a rest position 12 into a stamp position 13, whereby in the stamp position 13 the stamp impression 2 with the UV - Curable ink 5, which was taken from the text plate 3 by the ink pad 4, is generated on a preferably smooth surface 16a of the object 16 or workpiece 16 or document 16, and then the text plate 3 is returned to the rest position 12, the Control 22 is activated and at least one or more radiation sources 20 arranged on the stamp 1 and oriented in the direction of an impression surface 17 are activated to harden the ink.
    For example, it is possible that a switching element (not shown) for manually activating the control 22 and possibly for simultaneously activating the radiation source 20 (however, a separate control element can be arranged for this) is arranged on the stamp 1, so that preferably before the stamping process Control 22 is activated via the switching element. Then the stamp imprint 2 is generated by a stamping process, the stamp 1 not being removed from the position, so that by activating the light sources 20 the UV rays 19 are emitted, whereupon the stamp 1 can be removed from the position. However, it is also possible for the switching element to be in the form of a button (not shown), so that after the stamp impression 2 has been generated, the control 22 and the radiation sources 20 are activated by actuating the button, so that the UV-curable ink 5 is again UV -Beams 19 is cured. A disadvantage of the two processes described is that after the stamping process, the stamp 1 must be left in the stamp position in order to activate the radiation sources 20 for curing, so that the UV14 / 43
    UV Light Temple
    Rays 19 can cure the still damp and easily smudged stamp impression 2. This allows very good impression results to be generated, but the time required for a stamping process is very long. There is also the risk that after the stamping process, by moving the stamp 1, the stamp impression 2 can easily be blurred or destroyed by the anti-slip devices 18.
    It is preferably provided in the stamp 1 and its method according to the invention that an automatic or independent detection of a possible stamping operation is provided, so that the control 22 is automatically activated and the radiation source 20 is also switched on and off automatically, whereupon the control 22 to save energy is always activated as briefly as possible so that a high number of stamps can be generated with a charged energy source 23. The capacity of the energy source 23 is preferably designed in such a way that up to 1000 stamp impressions can be generated with one charge or that when used in shift operation, one shift can get by with one charge, that is to say, for example, in the automotive industry, the security stamp 1 at the beginning of a working shift from the Charging station is removed and then has sufficient energy available over the entire working shift.
    According to the invention, the control 22 is activated, in particular switched on, before or during the stamping process, the control 22 during or immediately after the stamping process, at least one or more radiation sources 20 on the stamp 1 oriented in the direction of an impression surface 17 of the stamp 1 for curing the stamp 1 Color 5 activates, in particular switches on, that is, when the stamp 1 is placed on the object 16, workpiece 16 or document 16, this is recognized, for example, by a touch button (not shown) or by a capacitive sensor system 24, so that the control 22 for lightning-fast switching on of the radiation sources 20 is activated in advance, whereupon the control 22 monitors whether and when a stamping operation is carried out, so that the light sources 20 act over a configurable period of time at a specific time or position of the text plate 3 or printing unit 7 be iviert. This ensures that, as usual, the user carries out a simple stamping process and can remove the stamp 1 immediately after the stamping process has been completed.

    During the return of the text plate 3 from the stamp position 13 into the rest position 12, in particular shortly before reaching or when reaching the rest position 12, at least one or more of the radiation sources 20 on the stamp 1 is preferably activated, in particular switched on, because this ensures that already a stamp imprint 2 is generated and therefore energy is not unnecessarily consumed. It is further achieved that the impression unit 7 with the text plate 3 covers the UV rays 19 in the direction of the ink pad 4, so that unwanted hardening of the ink 5 in the ink pad 4 is avoided. It is therefore advantageous if the radiation source 20 is preferably supplied with energy from the energy source 23 only immediately before the rest position 12 is reached or when or shortly after the rest position 12 is reached. The position can be, for example, via the capacitive sensor system 24, in which a capacitive element 25, 26, in particular capacitor plates, is embedded in the lower part 9 and in the upper part 8, a capacitive field being built up between the elements 25, 26, so that the capacitive field at the beginning of the stamping process is reduced, since the upper part 8 is pressed down, so that the control 20 is activated and at the end of the stamping process the field is increased again, so that by appropriately evaluating the field strength, the exact switch-on position for the light sources 20 can be determined. Of course, it is also possible that another type of sensor system 24, for example with micro-switches, light barriers, contact elements, magnetic switching elements, etc., can be used.
    To harden the paint 5, the radiation source 20 is therefore activated over a defined period of time, which can be set on or via the control 22, this period of time being far below the drying times for safety stamps known from the prior art, which begin with the prior art lasts from 10 seconds to a few minutes. According to the invention, the radiation source 20 is activated during or after the stamping process for a period of less than 2 seconds, preferably between 0.5 and 0.1 seconds, so that the radiation source 20 is already deactivated again when the stamp 1 is removed from the object 16 or workpiece 16 or document 16 is lifted off. Only through this short period of time is it possible that such a sequence with stamping and curing in one work step and with one device, namely preferably a hand stamp 1, is possible. However, in order to achieve such short exposure times, it is necessary that sufficient UV rays 19 act on the stamp impression 2, so that preferably several radiation sources 20
    16/43
    UV light stamps are used. One or two radiation sources 20 are preferably used for 0.5 cm 2 to 1 cm 2 stamp surface, ie the larger the stamp surface of the stamp 1 is designed, the more radiation sources 20 are required and used for the optimal curing, with the result being the performance the radiation source 20 must be taken into account. According to the current state of the art, LEDs with a wavelength of 420 nm to 365 nm are preferably used.
    In the case of the security stamp 1 shown in FIGS. 1 to 3, a stamp area of approximately 2 cm 2 is possible, so that six radiation sources 20 or six LEDs are used in order to provide a sufficient amount of energy or luminosity in the short exposure time or time period of less than 2 seconds, preferably between 0.5 and 0.1 seconds. The radiation sources 20 are arranged in the lower part 9 in the area of the contact surface 17a or impression surface 17, the light sources 20 emitting in the direction of the impression surface 17 into the interior 21 of the lower part 9. It is possible that the side surface of the lower part 8 is designed to be opaque for shielding against the UV rays 19, so that no rays can penetrate to the outside due to eye protection. This is possible with security stamps 1 of this type, since the impression area 17 is kept very small and the positioning is therefore simple. Of course, it is also possible that a transparent viewing window 27 is arranged for improved positioning, so that the user can look through the viewing window 27 into the interior 21 and thus an exact alignment is possible. The viewing window 27 is formed from a UV-impermeable material, in particular plastic, so that no UV rays 19 can penetrate through the viewing window 19 to the outside. For the sake of order, it is pointed out that instead of a viewing window 27, part or the entire surface of the lower part 9 can be produced with such a transparent, UV-impermeable material or plastic.
    The position of the controller 22 and the energy source 23 is at this
    Embodiment also on the lower part 9, so that all the lines required need only be integrated in the lower part 9, so that the energy supply via the lines is not hindered by any moving processes or elements. The controller 22 and the energy source 23 are preferably arranged between the spring element 11 and the stamp pad 4 in a space 28 created for this purpose. However, it is also possible for the spring element 11 to rest directly on a component, so that the energy source 23 and the controller 22 are fastened or arranged on the surface of the lower part 9.
    17/43
    UV Light Temple
    Of course, it is also possible for the control 22 and the energy source 23 to be arranged in the interior 21 above the stamp pad 4. It is also possible for the control 22 and the energy source 23 to be arranged separately from one another, for example the control 22 being positioned in the interior 21, preferably above the stamp pad 4, and the energy source 23 on the surface of the lower part 9 in the spring element 11, so that the energy source is easily interchangeable.
    It is advantageous if an interface 29, as can be reached schematically in FIG. 1 through an opening 30 or cutout in the upper part 8, is arranged on the stamp 1 and is connected to the control 22, so that data exchange preferably for setting the control 22, in particular the duration or switch-on time for the light sources 20, the activation time, etc., can be carried out. This interface 29 can also be used at the same time for the charging process of the energy source 23.
    Furthermore, it is duly mentioned that, as is known from the prior art, the stamp pad 4 can be replaced simply by pressing the stamp 1 slightly together, so that the text plate lifts off the pad impregnated with UV-curable ink 5 and then that Ink pad 4 can simply be pressed outwards and removed. A simple pillow change is important, since when ink 5 is used up, it can be re-soaked or that a replacement pad that has already been pre-soaked with UV-curable ink 5 is used as a new ink pad 4 in order to quickly have a usable stamp 1 again. It is advantageous here that the individual stamping processes, which are detected on the basis of the detection by the sensor system 24, are counted via the control 22 and, when a predefinable number of stamps is reached, information or a warning tone or signal tone is sent out, so that the user can determine the impression quality can check or replace the ink pad 4 due to quality requirements.
    4 and 5 a further embodiment of a stamp 1 with UV-curable ink 5 is shown. This in turn is a so-called self-inking stamp 1 of the Printy P4 series of the applicant. The main difference from the stamp of the Printy P2 series of the applicant shown in FIGS. 1 to 3 is that the stamp pad removal takes place differently, where this can be found in WO 2011/020608 A or AT 507833 A and their family members,
    18/43
    UV light stamp where the structure is essentially the same, only the size, in particular the size of the text plate 3 is different, so that the structure is no longer discussed in detail.
    By using the UV-curable ink 5, it is also necessary here that the stamp imprint 2 (not shown) must be irradiated with UV rays 19 from one or more radiation sources 20 in order to trigger the curing reaction. If this were not done, it would take a very long time for the stamp impression 2 to harden the stamp impression 2 via the UV rays emitted by the sun, so that the stamp impression 2 can easily be blurred or removed.
    In contrast to the first exemplary embodiment, the radiation sources 20 are now arranged on the impression unit 7. The radiation sources 20 are arranged on the opposite side to the text plate 3, so that they are aligned in the direction of the impression surface 17. The controller 22 and the energy source 23 are also arranged on the impression unit 7. This makes it possible for the light sources 20 to be soldered directly to the controller 22, in particular the control board, so that no lines outside the controller 22 are necessary. The energy source 23 can also be arranged directly on the controller, in particular on the opposite side to the radiation sources 20. It can thus be said that the controller 22, the energy source 23 and the radiation sources 20 form a common structural unit or module 31 which is attached directly to the impression unit 7. It is also possible that due to the modular design, the module consisting of the control 22, the energy source 23 and the radiation sources 20 are arranged in an independent housing, which is attached or arranged as an additional component on the impression unit, for example via a snap connection is. Thus, a commercially available stamp 1 can be retrofitted with such a module 31 at any time, an additional stamp pad 4 impregnated with UV-curable ink 5 having to be used for this purpose.
    To protect against contamination, it is possible for a transparent, replaceable protective cover 32 to be arranged, which is preferably designed at the same time as a lens 33, in particular a diverging lens, for better distribution of the UV rays 19 in the interior 21. It is no longer possible for one
    19/43
    UV Light Temple
    Stamping process, in which the impression unit 7 is rotated through the turning mechanism by 180 °, the radiation sources 20 can be contaminated with ink 5, which would harden immediately when the radiation sources 20 were activated and are therefore no longer or only very difficult to remove from the radiation sources become. If, on the other hand, the protective cover 32 becomes dirty, it can easily be replaced at any time, since the protective cover 32 is simply snapped onto the module 31 or the cover unit 7. Another important advantage, however, is the function as a lens 33, since here the UV rays 19 can be optimally scattered in the interior 21 of the lower part 9.
    In this exemplary embodiment, it is advantageous if the interface 29 (not shown) is arranged on the module 1 so that it can be contacted through the interior 21. It is also possible for the module 31 to be removed for charging the energy store or the energy source 23 or for data exchange. It is therefore possible that another loaded second module 31 is used and the stamp 1 is thus immediately ready for use again. It is also provided in this exemplary embodiment that the control 22 detects a position of the text plate 3 during the stamping process, the control 22 and / or the radiation sources 20 being activated in particular at certain detected positions, as already described in the exemplary embodiment in FIG. 1 to 3 is described and can be transferred to this embodiment of FIGS. 4 and 5, so that this has not been shown for the sake of clarity. The detection of the text plate 3 or the impression unit 7 is again preferably carried out capacitively via integrated capacitor plates or via contact elements or magnetic switching elements.
    In this stamp 1 of the embodiment 4 and 5 can in turn
    Stamp area of approximately 2-3 cm 2 are generated with a corresponding text plate 3, with only 2 radiation sources 20 now being used, since the UV rays are distributed through the lens 33. For the sake of order, however, it is mentioned that a plurality of radiation sources 20, for example four or six radiation sources 20 in the form of UV LEDs, are also used.
    6 to 7 is a stamp 1 with a 90 ° turning mechanism 11 of the applicant, for example with the brand name
    20/43
    UV Light Temple
    3912 based on documents WO2012 / 159728 A or AT 511453 B, so that the specific structure is not discussed in detail, since this can be found in the documents.
    The stamp 1 is connected via an interface cable 34 to an external component, in particular a computer 35 and / or charger, for charging and for data exchange in the rest position 12, as is shown schematically in FIG. 7.
    In the case of the stamp 1, all the components required for the UV-curable process, in particular the radiation source 20, the controller 22, the energy source 23, the interface 29, etc., are arranged on the lower part 9. However, since in the so-called 90 “stamp 1 shown, the impression unit 7 is arranged at an angle of 90 ° to the impression surface 17 or the object 16, workpiece 16 or document 16, in the rest position 12, sufficient space is created in the interior 21 for the Radiation sources 2 hiss the impression unit 7 and to arrange a front side 36 of the stamp 1. Thus, in the rest position 12 or immediately before activating the radiation sources 20, the UV rays 19 can be emitted unhindered in the direction of the impression surface 17, without this being impeded by the impression unit 7. At the same time, the impression unit 7 serves as a cover for the stamp pad 4, in particular the pad in the stamp pad 4 impregnated with UV-curable ink 5, so that no UV rays 19 can reach the stamp pad 4 in the interior 21. It is also possible for cover elements 37, which are preferably of elastic design, to be arranged on the impression unit 7 or on the ink pad 4 themselves, so that they can be easily deformed when they strike the housing.
    Another difference from the previously described exemplary embodiment lies in the fact that with this stamp 1, in addition to the light sources 20 attached to the control 22, additional light sources 20 are arranged in the area of the impression surface 17, as indicated schematically below the impression unit 7, so that several Positions in the interior 21 for better illumination of the entire impression area 17, the light sources 20 are distributable can be distributed.
    7 to 9 show a further exemplary embodiment for the arrangement of the essential components in the stamp 1, with the stamp 1 again being a known one
    21/43
    UV Light Temple
    Model of the Printy P4 series, namely a P4 4912, shown by the applicant. The structure of the stamp 1 can be found in the granted European patents EP 2591921 B, EP2384283B, EP2591919 and EP25991920B, so that the details are no longer discussed.
    With this construction, the individual components, in particular the light sources 20, the controller 22, the energy source 23, etc., are now arranged separately from one another. The control 22 and energy source, as well as all other parts, such as the interface 29 (not shown), are arranged in the upper part 8, whereas the light sources 20 are arranged in the lower part 9, in particular in the interior 21 of the lower part 9, for irradiating the impression surface 17 , The advantage of this solution lies primarily in the fact that a much more extensive control 22 and a larger energy source 23 or several additional components, such as the interface, etc., can be used, since there is much more space than is possible in the lower part 9 , It is also possible that access to the electrical or electronic components can be made possible from the outside by forming a so-called double floor (not shown). There is also the possibility that the controller 22, the energy source 23 and other components, such as the interface 29 on the outside of the upper part 8, for example below the transparent window element 38 for inserting a sample print and for the control and power supply of the Luminous sources 20 required leads to the inside.
    However, in order for the light sources 20 to be supplied in the lower part 9 in such a construction, an electrical connection must be established between the upper part 8 and the lower part 9. This can be done, for example, by using conductive axes 15 or electrically conductive inserts 39 in the region of the axes 15, via which a so-called sliding contact 40 is produced with the turning mechanism 14, in particular the guide groove, so that the energy from the upper part 8 via the inserts 39 Sliding contact 40 is passed to the lower part 9 and thus the light sources 20 are supplied with energy for a defined period of time for emitting the UV rays 19, as is shown schematically. However, it is also pointed out that flexible lines can be used to connect the upper part 8 to the lower part 9, which can compensate for the pushing together or pressing together of the two parts. It is essential that with such training the
    22/43
    UV Light Temple
    Lower part 9 is formed in electrical connection for transmitting the energy to the upper part 8, so that sufficient energy is made available to the light sources 20 in the lower part 20.
    11 and 12 show a further exemplary embodiment of a stamp 1, a so-called flash stamp 1 now being used, in which the ink 5 seeps through the text plate 3 and a stamp impression 2 can thus be generated, whereby on the detailed design of the stamp 1 and its mode of operation will not be discussed in more detail, since a large number of such systems are already known.
    In this variant, the radiation sources 20 on the stamp 1 are preferably arranged on the upper part 8 or on side surfaces 41 for manual alignment to the impression surface 17, that is to say that first the stamp impression 2 according to FIG. 11 is generated, then the stamp 1 is turned over, according to FIG. 12, and, for example, by activating a button 42, the light sources 20, which are directed manually in the direction of the stamp impression 2, are switched on, the controller 20 carrying out the control over the period of time.
    Furthermore, it can be seen from the exemplary embodiment that the light sources 20 are arranged on the upper side of the upper part 8, in particular below a cover 43, so that the light sources 20 are protected against contamination. The
    For the sake of order, however, it is pointed out that the light sources 20 can also be exposed or that they are embedded in a depression, so that the stamp 1 can be placed over the stamp imprint 2 and when the light sources 20 are activated, they start the curing process.
    A further possibility of arranging the light sources 20 is shown in FIG. 13, in which the light sources 20 are arranged in a sealing cap 44 of the stamp 1. The light sources 20 are preferably arranged in the inner region 45, so that the closure cap 44 can simply be placed over the stamp imprint 2 and the light sources 20 can be switched on with the button 42 (not visible) arranged on the side opposite the light sources 20. Of course, it is also possible to arrange the light sources 20 on the outside of the closure cap 44.
    23/43
    UV Light Temple
    The use of the additional component of the stamp 1 makes it possible for the controller 20 and the energy source 23 and further additional components such as the interface 29 to be simply integrated therein, since there is sufficient space for accommodating the components.
    According to the invention, it is thus possible to create a method or sequence for producing a stamp imprint 2 with curable ink 5, in which the text plate 3 with the negative stamp imprint 2 is moved from a rest position 12 into a stamp position 13, so that in the stamp position 12 the stamp impression 2 with the color 5 is generated on a preferably smooth surface 16a of a document 16 or object 16 or workpiece 16, and then the text plate 3 is returned to the rest position 12, a control 22 being activated, after the generation of the stamp impression 2, the stamp 1 or an additional component of the stamp 1, in particular a closure cap 44, with light sources 20 arranged thereon, is manually aligned with the stamp impression 2 and the light sources 20 for irradiating the stamp impression 2 are activated.
    Furthermore, it is possible that additional safety measures can be integrated in stamp 1. For example, one or more, in particular four, switching elements or contact switches can be installed in the anti-slip devices 18, so that when the stamp 1 is placed on an object 16, workpiece 16 or document 16, these are activated or deactivated and thus release a UV-curable stamp process. This prevents the user from accidentally activating the radiation source 20 when the stamp 1 is compressed in the air, since the stamp 1 must be placed on an object 16, workpiece 16 or document 16.
    Furthermore, indirect irradiation (not shown) of the stamp impression 2 with the UV rays 19 is possible, in which the radiation source 2 is not aligned directly in the direction of the stamp impression 2, but rather the rays 19 are received by a guide element and subsequently deflected or deflected in this way are transported such that the rays run or radiate on exiting the guide element in the direction of the impression surface 17 or the stamp impression 2. That is to say that the radiation source 20 is arranged in the upper part 8 and / or lower part 9, whereby for irradiating the stamp impression 2
    24/43
    UV Light Temple
    Guide elements, in particular light guides, mirror system, which deflect the emitted rays, in particular UV rays 19, in the direction of the impression surface 17.
    For the sake of order, it is pointed out that the closure cap 44 for the
    Self-inking stamp according to FIGS. 1 to 10, as well as for the flash stamp according to FIGS. 11 and 12, can be designed, which can be adopted depending on the design, as is known from the prior art.
    For the sake of order, it should finally be pointed out that, for better understanding, drawings have been shown sometimes to scale and / or enlarged and / or reduced. It is also pointed out that the individual exemplary embodiments of FIGS. 1 to 10, in particular the arrangement of the elements for the curing process, are interchangeable with one another and not for the one shown
    Embodiment is limited.
    Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also form independent, inventive or inventive solutions.
