    Field of the invention
    The invention presented below relates to a combination printing device for secure files (particularly marketable securities) that enables combined printing using three printing techniques, ie screen printing, magnetic printing and high-pressure, in a single printing pass.
    Background of the invention
    Most security printing devices can only print using a single printing technique. Thus, for example, single-sided printing devices with Sinzelbiatteinzug and rotating Siebdruckplatie use only screen printing technology and high-pressure devices can only print in high-pressure technology. As soon as print products have to be produced using a plurality of printing methods, successively different printing devices, each with a specific technique, must be used for printing. Therefore, printing lines of a plurality of printing apparatuses having different printing techniques must each be configured for screen printing, high-pressure, etc. Since any type of equipment must be provided with Bogeniransportvornchtungen, the
    Printing lines very long and require a lot of footprint in the production area, which increases the production costs accordingly.
    The Chinese patent 200410084389.9 teaches a rofatty acid printing machine consisting of a paper feeder, a paper detecting device, a screen printing part and an associated high pressure part, etc., in which a screen printing unit coordinates with a high pressure machine, but integrated printing with three printing techniques, screen printing, magnetic printing and high pressure is not a single paper pass is possible
    The Chinese patent 200880005435.8 teaches a "cylindrical body for aligning magnetic particles and ink-coated substrates with sheets or sheets." The known cylinder body 10 having magnetic-generating functions has a certain position circumferentially with respect to the shaft member and both rotate synchronously. Thus, a sheet is always in a locked state when it is delivered to the cylinder body 1.0, in particular, it is fixed on the Zyiinderkorper also during the Öbergabeprozess of the bow.Thus, if a sheet transfer system of the known cylinder body 10 with magnetic-generating devices a sheet transfer to a sheet transfer system of In other words, the holding force of the cylinder body 10 affects the accuracy and stability of sheet transfer to some extent Production sheet transfer between cylinders unstable and accuracy low, which suffers the quality of the printed product; Therefore, in the known structure, the cylinder body 10 is more suitable for pressure environments similar to those shown in Fig. 13 without sheet transfer. Further, in the known structure (although the suction opening in the central shaft of the magnet aligning cylinder can switch between holding and non-holding effects by selectively using an element is pushed over one another) such an arrangement can be made with reasonable effort. Thus, their structure is relatively complex and labor intensity in production is increased. Moreover, the axial position of the prior art magnetic field generating device is not adjustable on the support ring. Only the fixing position of the supporting ring in the axial direction relative to the central shaft can be adjusted, which considerably restricts the flexibility in the position adjustment of the magnetic-field-generating device.
    Since the ink layer of screen printed products is thick, it must be dried to ensure: the quality of the printed product. In prior art screen printing devices, the printed product is usually dried by a combination of hot air drying and infrared / UV drying. However, this combined drying process requires a long drying path, which not only takes up a lot of space in the apparatus, but also causes the problem that the
    Quality of the printed product is affected if it can not be dried in time. For this reason, an apparatus for baking ink on sheet surfaces by ultraviolet light has been developed, and in the drying process, printing cylinders with cooling effect must cool the sheet surface simultaneously with the drying, so that the sheet security in the drying process is increased. For example, the teachings of Chinese patent 200820009427.8 describe a switchable infrared infrared dryer for an internal hollow cooling / transfer roller provided at the lower part of a UV light box. The cooling water is supplied through the water tube and the rotary valve group to the Cavity of Kühh / Obergabewalze introduced. When the sheet is dried by the OV light box, (to prevent shrinkage of the sheet due to the high temperature of the UV Uehtbox), the rotary valve group is opened and the K0h! ~ / Übergabewaize inside is filled with cooling water, so that she absorbs the heat from the arch surface.
    The printing process is a complex process and the known structure of the cooling transfer roller merely cools the sheet surface. However, if the cooling transfer roller can not engage with other paper transporting cylinder, the sheet will float on the surface of the transfer roller and thus become unstable in the transfer process. For example, during the handover process, the back end of the sheet may shift, different areas of the sheet may not be in the same level, and so on.
    As a result, in high-output printing plants, and predominantly comprehensive techniques, the prior art printing devices and devices can only be equipped with devices having one or two combined printing processes. As a result, the cost of investing and managing the equipment is high, the production run takes a long time and a lot of manpower is required. In addition, the maintenance costs increase, so that the production costs are high and the
    Competitiveness in the market is impaired. In addition, the screen printing requires very large drying systems, whereby the known printing presses with integrated printing process continue to have the disadvantage that the production and storage areas need a lot Piatz.
    In view of the above-described disadvantages of the prior art and after many years of experience in manufacturing and construction in this and related fields, the inventor has developed an integrated printing apparatus according to the present invention in which three printing methods (screen printing, magnetic printing, high-pressure) are possible and solves the problems that arise in the sheet transfer between different printing devices, the offset of printed image and text or the necessary turning over bows, Furthermore, the transport route should be as short as possible and much more This means that the present invention could not only meet the requirements of the printing process and ensure the quality Druek, but also greatly reduces the transport path and reduces the necessary scope of equipment, overview of the invention
    An object of the invention presented herein is a single-sided rotary printing apparatus for a plurality of methods, and more particularly to an integrated printing apparatus with which three methods (screen printing, magnetic printing, high-pressure) are possible in a single printing pass.
    A further subject of the present invention is a magnetic trimming cylinder which satisfies various print product requirements, is conveniently adjustable, has a simple structure and is capable of improving the quality of the printed product.
    Another object of the present invention is a paper transport and drying type finder for holding and cooling sheets during the process of printing on paper in sheet or web like form,
    Therefore, the invention presented herein discloses an integrated pusher in which at least one unit for light curing of inks, a screen printing unit, is used in FIG
    Magnetic alignment unit for magnetic ink and a high-pressure unit are provided, wherein the units with each other by a
    Paper transport system are connected. in said combination printing apparatus, the ink-curing unit includes a UV drying apparatus and / or an infrared drying apparatus and a paper transport and inking apparatus

If the ring carrier 22 or other element has to be readjusted, the tensile force of the cover plate 23 is reduced by loosening the fastening screw 261 or the cover plate 23 moves away from the clamping of the upper and lower pressure plates 251, 252 by unscrewing the positioning screw 262 Cover plate 23 is to be stretched, the lower pressure plate 252 is stretched by adjusting the mounting screw 261 to the end of the ring carrier 22 out, so that the cover plate 23 is stretched.
    As can be seen from the common observation of Figs. 7 and 12, the spindle of the magnet breaker is axially provided with a hollow air passage 2111 which is usually arranged coaxially with the spindle 211. The side wall of the spindle 211 is provided with a plurality of openings communicating with the air passage 2111. Both outer ends of the spindle 211 are provided with one each with an annular shoulder 2113. The annular shoulder 2113, the inner wall of the cylinder body 212, and the spindle 211 constitute the air chamber 213. The air opening 2112 can suck the air out of the air chamber 213.
    In order to stably transfer the printed matter sucked to the magnet aligning cylinder to the next cylinder and to avoid errors in the transfer of the printed matter, it is a possible solution to further attach two radially protruding air chamber distributing ledges 271, 272 in the longitudinal direction outside the spindle 211 Air chamber distribution ledges 271, 272 divide the circumferential cavity between the spindle 211 and the cylinder body 212 into two spaces, one of which is a vent chamber 213 darsiellt. In the space inside the air chamber 213, the spindle 211 is provided with an air hole 2112 communicating with the air passage 2111. Therein, the through hole 2121 is provided on the cylinder body 212 of the magnetic cylinder, preferably in a cross section corresponding to the air chamber 213. Since the first retaining hole 222 of the ring carrier 22 is in communication with the through hole 2121 and the second retaining holes are uniformly distributed on the cover plate 23, it is obvious that in the process of relative rotation between the cylinder body 212 and the spindle 211, the surface of the magnet Ausrlchtzylinders 20 can shade between the effects of suction and non-aspiration,
    As is apparent from FIGS. 7 and 12, in order to achieve a more stable connection between the air chamber distribution lines 271, 272 and the spindle 211, two groups of mutually corresponding grooves 2114, 2115 in the radial direction are preferably located on opposite inner sides of the two shoulders 2113 intended. The two Luftkammerteilungsieisten 271, 272 are each embedded in the grooves 2114, 2115 and fixed by screws with the lockers! 211 connected, The cylinder body 212, the two Sch-u'item 2113 of the lockers! 11 and the two Luftkammerteifungsieisteo 271,272 form the air chamber 213,
    Furthermore, between the shoulders 2113, each of the two air chamber distribution strips 271, 272 and the Zyiinderkörper 212 is a Spieipassung, i. the outer diameter of the shoulder 2113 and the distance between the outer end faces of each of the
    Luftkamm.erteilungslei.sten 271; 272 and the center of the Zyiinderkörpers 212 is slightly smaller than the inner diameter of the Zyiinderkörpers 212, so that the cylinder body 212 is freely rotatable on the spindle 211 and without any disturbing friction with the Luftkammerteilungsleisten. In order to achieve the above object, preferably, each of the air-chamber distribution bars 271, 272 when the air-chamber distribution bars are attached to the spindle 211 is set so that a clearance between the outer-side and the inner wall surface of the cylinder body 212 0.1 mm to 4 mm, and further, the shoulder 2113 between the outer peripheral surface and the inner wall surface of the Zyiinderkörpers 212 has a clearance of 0.1 mm to 4 mm.
    As shown in Fig. 3, two air chamber distribution ledges 271, 272 divide the rotary air valve 21 into a suction-effect space (air chamber 213) and a non-suction-effect space. Since the spindle 211 in section A is not provided with any air opening 2112, the section A forms the non-suction-effect space therein. The portion enclosed by the angle α (380 * - A), since the spindle 211 is provided with the air opening 2112, forms the space with the suction effect, that is, this space is formed as the air chamber 213 Turning the Zyiinderkörpers 212 the passage opening 2121 provided thereon enters the air chamber 213, which receives the Anssaugwirkung this section of the Zyiinderkörpers 212 corresponding ring carrier 22. Then, when the cylinder body 212 continues to rotate such that the passage opening 2121 provided therefrom leaves the air chamber 213 and enters the section A, the ring carrier 22 corresponding to this portion of the cylinder body 212 loses the suction effect.
    The principle of operation of the Magnetausrichtzylinders 20 is that the spindle 211 does not rotate and the cylinder body 212 by a drive system, for example by a gear drive, is rotationally driven. When the passage 2121 of the cylinder body 212 reaches the portion A between the two air chamber distribution bars 271, 272 during rotation of the cylinder body 212, the magnet alignment cylinder 20 has no suction effect because the spindle 211 has no air hole 2112 in this portion. When the cylinder body 212 is rotated so that the provided thereon. Through hole 2121, the air chamber (213) between the two Luftkammerteilungsieisten 271. 272, i. reached the portion 300 ° - A, are the second holding hole on the cover plate 23, the first Haiteöffnung 222 on the ring carrier 22 and the through hole 2121 on the cylinder body 212 in a line-up connection and the air suction sucks through the air passage 2111, the air opening 2112 of lockers! and the air chamber 213 from the surface of the Magnetausrichtzylinders 20, so that the surface of the
    Magnetic view detonator 20 has the Ansaugwärkung. When the peripheral surface of the cylinder body 212 having the through hole 2121 in the rotary air valve 1 completely enters the portion (360 ° -Δ) between the two air chamber dams 271, 272, this part of the surface of the cylinder body 212 has the largest holding force, i. The MagneiNightzylmder 20 achieves the maximum shark effect. With the rotation of the cylinder body 2121, the magnet aligning cylinder 20 switches between two states with and without suction effect. By constructing the rotary air valve, the magnet breaker ensures the stability of transfer of the printed matter, reduces the instability factors in the magnetization process of the printing unit such as biassing and improves the quality of magnetic alignment Pattern in printed matter.
    Furthermore, on the one hand, when in the Magnetausrichtzylinder the axial and circumferential positions of the magnetic-generating device 221 of the ring carrier 22 nachgestefit must be nachgestefit according to the layout of the printed product, since the annular bearings 22 with a certain distance L (see Fig. 2) are spaced apart and each ring carrier 22nd is fixedly connected to the Zyiinderkörper by the frictional force that is produced between the Festungsgungskei 2124 and the keyway, the
    Attachment between the Befungsflgungskeil 2124 and the keyway 2122. 2123 by loosening the connecting screw 28, which connects the ring carrier 22 with the Befestigungskeii 2124, are released, so that common axial movement in the keyway and thereby making the axial adjustment of the magnetic field generating device 221 and reaching the purpose of adjusting the axial position of the magnetic field generating device 221 is possible. On the other hand, when the position of the magnetic field generating device 221 needs to be circumferentially adjusted, the attachment of the surface of the magnetic field generating device 221 can be released by loosening the adjusting screw 227, since the magnetic field generating device 221 is fixed by the pressure plate 226 and the adjusting screw 227 in the annular groove 2251 of FIG Ring carrier 22 is fixed, and so the magnetic field generating device 221 is moved in the annular groove 2251 until it reaches a suitable position. Then, the adjusting screw 227 is tightened to fix the magnetic field generating device 221. Thereby, the position of the magnetic field generating device (221 in the circumferential direction can be easily adjusted.
