Description

Field of the invention

The invention presented below relates to a combination printing device for secure files (in particular marketable securities), with which combined printing using three printing techniques, ie screen printing, magnetic printing and high-pressure, is possible 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 single-sheet feeder and rotating screen printing plate can only use 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 must be equipped with various printing techniques for screen printing, high-pressure, etc., respectively. Since each type of equipment must be provided with sheet transport devices, the printing lines are very long and require a lot of floor space in the production area, which increases the cost of production accordingly.

The Chinese patent CN 100 382 963 C teaches a rotary label printing machine which consists 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 possible in a single paper pass is.

The Chinese patent CN 101 631 680 B teaches a "cylindrical body for aligning contained in printing ink or paint as a carrier magnetic particles and applying to sheet or sheet-like substrate". The known cylinder body 10 with magnetic field generating devices has a certain position in the circumferential direction relative to the shaft member and both rotate synchronously. Thus, a sheet is always in a fixed state when it is delivered to the cylinder body 10, in particular it is held on the cylinder body during the transfer process of the sheet. Thus, when a sheet transfer system of the known cylinder body 10 with magnetic field generating devices performs sheet transfer to a sheet transfer system of another cylinder or device, the holding force of the cylinder body 10 affects, to some extent, the accuracy and stability of sheet transfer. Therefore, in the known construction in the current production, the sheet transfer between cylinders are unstable and the accuracy is low, including the quality of the printed product suffers. Therefore, the cylinder body 10 of the known construction is more suitable for printing environments similar to those in FIG 13 presented without sheet transfer. Further, in the known structure (though the suction port in the central shaft of the magnet aligning cylinder can switch between holding and non-holding action by being selectively overlapped with an element), such an arrangement can be made with reasonable effort. Thus, their structure is relatively complex and labor intensity in production is increased. In addition, the axial position of the magnetic field generating device according to the known prior art is not adjustable on the support ring. It can only be adjusted in the axial direction with respect to the central shaft, the mounting position of the support ring, which substantially limits the flexibility in the position adjustment of the magnetic field generating device.

Since the color layer of screen printed products is thick, it must be dried to ensure the quality of the printed product. In screen printing devices according to the known prior art, 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 machine, but also causes a problem that the quality of the printed product is impaired 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. In the drying process, printing cylinders with cooling effect must cool the sheet surface simultaneously with the drying, so that the sheet security is increased in the drying process. For example, the teaching of the Chinese utility model describes CN 201 198 221 Y a "Switchable Ultraviolet Infrared Printer Drying Device" means an inside hollow cooling / transfer roller provided at the bottom of a UV light box. The cooling water is introduced through the water pipe and the rotary valve group to the cavity of the cooling / transfer roller. When the sheet is dried by means of the UV light box, (to prevent shrinkage of the sheet due to the high temperature of the UV light box), the rotary valve group is opened and the cooling / Transfer roller is internally filled with cooling water, so that it absorbs the heat from the arc 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 print shops and predominantly comprehensive techniques, the printing lines of prior art printing devices and devices can only be equipped with devices having one or two combined printing methods. 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 of space.

The CN 102085747 A discloses a printing device for bills in which various printing units are arranged around a central printing cylinder.

The DE 103 12 870 A1 discloses a digital printing machine for sheetfed printing.

The US 3,037,557 A discloses a vacuum cylinder for a printing machine with less heat generation.

The DE 10 2005 062 203 A1 discloses a method for transporting printing material sheets and sheet transport means for carrying out the method, wherein the printing material sheets is held with a coolable sheet support surface and an intermediate adhesive.

The DE 10 2004 032 111 A1 discloses a guide for substrates with a heat dissipation through integrated, parallel and coolant flowed through the cooling capillary.

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 which 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 can not only meet the requirements of the printing process and ensure print quality, but also greatly shortens the transport path and reduces the amount of equipment required.

Compared with the prior art, the invention presented herein has the following characteristics and advantages:

The combination printing apparatus according to the present invention enables the passage of the sheet through a paper feed section, a paper feed cylinder, a first paper feed cylinder, printing sections, and a paper collecting section in a single printing operation. Integrated screen printing, magnetic printing and letterpress printing can be completed on one side of a single paper. The process of paper transport, printing and collecting can finally be finished.

In a printing apparatus, the present invention supplies the sheets one at a time, and the integrated printing can be completed by continuous screen printing, magnetic printing and high-pressure. The finished printed products are delivered to the paper collecting section. Thus, the present invention over the prior art can significantly shorten the production cycle, significantly reduce the investment cost of equipment, significantly reduce the space required for production and storage, and reduce the need for human labor. The invention presented herein may include i.a. to safely print secured and marketable securities.

The present invention uses for drying the printed product simply drying variants of UV or infrared drying or a combined variant of UV and infrared drying. This means that the drying path in the invention presented herein is relatively short and so the quality of the printed product can be easily ensured. Timely drying is especially important for printed products with magnetic alignment. In the process of drying the printed product, the present invention provides the printed matter through the paper transporting and drying cylinder in which the sheet suction effect makes the printing of the printed product more stable and smoother within the drying process. The cooling process provided in this case can cool the surface of the sheet, while ensuring a stable transport process. In particular, the dry sheet surface temperature and the sheet moisture loss are reduced, distortion caused by shrinkage of the sheet is avoided, and the drying effect and the security of the printed product are ensured.

Further, both of the paper transporting and drying cylinders and the magnetic aligning cylinder according to the present invention use the structure of a rotary air valve which divides the area of the outer surface as the working surface of the paper transporting and drying cylinder and the magnet aligning cylinder into an aspirating region and a non-adhering region that suction and non-aspiration are switchable against each other. Compared to the existing prior art, the invention presented herein is simple in structure. By an appropriate arrangement of the transfer position between the cylinders, it ensures that the transfer process of the printed products always takes place in the region of Nichtansaugwirkung. This eliminates the error by the transfer of the printed product and the stability of the transfer of the printed product is improved. In addition, the holding force on the cylinder surface causes the instability factors in magnetizing the printed product such as free-floating sheet decreases and the quality of the magnetic alignment of the printed product is improved.

In addition, both the paper transport and drying cylinder and the magnetic alignment cylinder according to the invention presented herein are provided with at least one group of gripping bars for sheet transfer and transfer during drying or magnetic alignment of the printed product, thereby improving the quality of the magnetic alignment pattern of the printed product is guaranteed.

The screen cylinder according to the invention presented herein employs the independent servo-driven control technology so that it does not have to idle with the machine when printing is not being performed. The non-pictorial text part of the screen printing cylinder stops just in time under the cylinder after being dropped off. As a result, leakage of ink and contamination of the screen plate cylinder are largely avoidable. The losses / wastes generated in shutdowns after shutdown can be reduced.

According to the invention presented herein, after screen printing, the sheet must be transported between the second paper transport cylinder, the magnet alignment cylinder and the third paper transport cylinder and then to the drying unit. In order to prevent displacement of the printed image or text, the second paper transport cylinder and the third paper transport cylinder use the kiss cylinders according to the invention presented herein so that in the transport process the sheet is always applied to the pads under the negative pressure and the image / text page and the non-image page of the sheet never comes into contact with the cylinder. This ensures that moving between image and text is avoided.

To the sucked on the Magnetausrichtzylinder printed product stable to the next It is a possible solution to be able to deliver cylinders and to avoid errors in the transfer of the printed product, furthermore two radially outstanding air chamber distribution strips 271 . 272 in the longitudinal direction outside the spindle 211 to fix. The two air chamber distribution strips 271 . 272 divide the circumferential cavity between the spindle 211 and the cylinder body 212 in two rooms, one of which is an air chamber 213 represents. In the room inside the air chamber 213 is the spindle 211 with an air opening 2112, which communicates with the air passage 2111 communicates. This is the passage opening 2121 on the cylinder body 212 the Magnetausrichtzylinders preferably in a cross section, which the air chamber 213 corresponds, provided. Because the first holding hole 222 of the ring bearer 22 with the passage opening 2121 communicates and 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 Magnetausrichtzylinders 20 between the effects of suction and non-aspiration can switch.

Like from the 7 and 12 Taken together, are to provide a more stable connection between the Luftkammerteilungsleisten 271 . 272 and the spindle 211 to reach, preferably on opposite inner sides of the two shoulders 2113 each two groups of mutually corresponding grooves 2114 . 2115 provided in the radial direction. The two air chamber distribution strips 271 . 272 are each in the grooves 2114 . 2115 embedded and secured by screws with the spindle 211 connected. The cylinder body 212 , both shoulders 2113 the spindle 11 and the two air chamber distribution strips 271 . 272 form the air chamber 213 ,

Continue to exist between the shoulders 2113 , each of the two air chamber distribution strips 271 . 272 and the cylinder body 212 a clearance fit, ie the outer diameter of the shoulder 2113 and the distance between the outer end faces of each of the air chamber distribution strips 271 . 272 and the middle of the cylinder body 212 is slightly smaller than the inner diameter of the cylinder body 212 so that the cylinder body 212 on the spindle 211 is freely rotatable and without any disturbing friction with the Luftkammerteilungsleisten. In order to achieve the stated object, it is preferable that each of the air chamber distribution bars 271 , 272, when the air chamber dividers on the spindle 211 are fixed, adjusted such that between the outer end face and the inner wall surface of the cylinder body 212 a clearance of 0.1 mm to 4 mm, and further the shoulder 2113 between the outer peripheral surface and the inner wall surface of the cylinder body 212 has a clearance of 0.1 mm to 4 mm.

As in 3 shown, divide two air chamber distribution strips 271 . 272 the rotary air valve 21 into a room with suction effect (air chamber 213 ) and a room with non-suction effect. Because the spindle 211 is provided in section A with no air opening 2112, forms therein the section A, the room with Nichtansaugwirkung. The section enclosed by the angle α (360 ° - A) forms, since the spindle 211 with the air opening 2112 is provided, the room with suction, ie that this space as the air chamber 213 is trained. This means that if while turning the cylinder body 212 the passage opening provided thereon 2121 in the air chamber 213 enters, this section of the cylinder body 212 corresponding ring carrier 22 receives the suction effect. Then, when the cylinder body 212 continues to rotate such that the passage opening provided thereon 2121 the air chamber 213 leaves and enters the section A, loses that proportion of the cylinder body 212 corresponding ring carrier 22 the suction effect.

The principle of operation of Magnetausrichtzylinders 20 is that the spindle 211 not rotates and the cylinder body 212 by a drive system, for example by a gear drive, is driven in rotation. When the passage opening 2121 of the cylinder body 212 during the rotation of the cylinder body 212 section A between the two air distribution boards 271 . 272 reached, has the Magnetausrichtzylinder 20 no suction because the spindle 211 no air opening in this section 2112 Has. When the cylinder body 212 is rotated such that the passage opening provided thereon 2121 the air chamber ( 213 ) between the two air chamber distribution strips 271 . 272 , ie, reaches the portion 360 ° - A, are the second holding hole on the cover plate 23 , the first holding hole 222 on the ring bearer 22 and the through hole 2121 on the cylinder body 212 in a line-up and the air exhaust sucks through the air passage 2111, the air opening 2112 the spindle and the air chamber 213 Air from the surface of Magnetausrichtzylinders 20 off, leaving the surface of the magnetic field deterrent 20 has the suction effect. When the peripheral surface of the cylinder body 212 with the passage opening 2121 in the rotary air valve 1 completely into the section (360 ° - A) between the two air chamber dividers 271 . 272 enters, this part of the surface of the cylinder body 212 the largest holding force, ie the Magnetausrichtzylinder 20 achieves the maximum holding effect. With the rotation of the cylinder body 2121 the magnet alignment cylinder switches 20 between two states with and without suction effect. By the construction of the rotary air valve, the magnetic alignment cylinder ensures the stability of the transfer of the printed product, reduces the instability factors in the Magnetization process of the printing unit such as sheet displacement and improves the quality of the magnetic alignment of the patterns in the printed product.

Furthermore, on the one hand, if in the Magnetausrichtzylinder the axial and circumferential positions of the magnetic field generating device 221 of the ring bearer 22 must be readjusted according to the layout of the printed product, since the ring carrier 22 with a certain distance L (see 2 ) are spaced from each other and each ring carrier 22 is firmly connected to the cylinder body by the frictional force which is produced between the mounting wedge 2124 and the keyway, the attachment between the mounting wedge 2124 and the keyway 2122 . 2123 by loosening the connecting screw 28 which the ring bearer 22 with the mounting wedge 2124 connects, so that common axial movement in the keyway and thereby making the axial adjustment of the magnetic field generating device 221 and achieving 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 must be adjusted in the circumferential direction, the attachment of the surface of the magnetic field generating device 221 by loosening the adjusting screw 227 be solved because the magnetic field generating device 221 through the pressure plate 226 and the adjusting screw 227 in the ring groove 2251 of the ring bearer 22 is fixed, and so the magnetic field generating device 221 in the ring groove 2251 is moved until it reaches a suitable position. Then the adjusting screw 227 attracted to the magnetic field generating device 221 to fix. This allows the position of the magnetic field generating device ( 221 be adjusted comfortably in the circumferential direction.
