Description
Technical Field
The invention relates to an ink transferring and conveying method and device for image-text printing and printing equipment with the device.
Background
In order to ensure normal and orderly social and economic activities, anti-counterfeiting printing is adopted in the printing process of valuable paper such as bank notes, securities, bills and the like.
In order to improve the anti-counterfeiting level of the valuable paper, people usually print two or more colors of pictures and texts on the valuable paper, and for the picture and text printing which is continuous along the circumferential direction of a printing plate cylinder, different color areas are demarcated on the same rotating surface of the printing plate cylinder, so that ink is supplied to the different color areas at fixed points to ensure the accuracy of the demarcations.
The known fixed-point inking method is to make the diameter of the plate cylinder an integral multiple of the diameter of the ink transfer cylinder, so as to ensure that each point on the surface of the plate cylinder always corresponds to a certain point on the surface of the ink transfer roller in a one-to-one correspondence in the rotating ink transfer process. Although this method of spot inking is easy to implement, since a certain point on the plate cylinder is always inked by a certain fixed point on the surface of the ink transfer roller, areas on the surface of the plate cylinder are inevitably starved during printing, which may directly affect the quality of the product and the anti-counterfeiting properties of the securities, even produce waste products.
To avoid the potential starvation of a region of the plate cylinder surface that is prone to the known techniques described above, the inventors have considered it possible to cause relative repositioning of the ink transfer rollers each time they transfer ink to the plate cylinder. Chinese patent No. 200410050147.8 discloses a "misalignment ink transfer number connection printing device". The number printing unit comprises a number cylinder, an impression cylinder and two groups of inking systems, wherein each group of inking system consists of an ink supply device, a color mold roller and an ink transfer roller, the diameter of the color mold roller is matched with that of the ink transfer roller, the ink transfer rollers in the two groups of inking systems are number cylinder ink transfer, and the diameter ratio of the number cylinder to the ink transfer roller is a non-integer. After the diameter of the number cylinder and the diameter of the ink transfer roller are made into a non-integral multiple relation, in the working process, the number cylinder rotates J circles and the ink transfer roller rotates P circles to complete an ink transfer cycle, so that in each ink transfer period, the same color area of each number on the number cylinder is transferred J times by J ink storage areas on the corresponding ink transfer roller, and therefore each number can be fully supplied with ink, the defect of insufficient ink is overcome, and the printing quality is guaranteed.
The offset ink-supplying number wiring printing device designs the diameter of the number cylinder as a non-integral multiple of the diameter of the ink transfer roller, so that the diameter of the ink transfer roller, the color mold roller and the number cylinder is limited by the breadth of a printing product although the aim of offset ink transfer is achieved. This known construction requires that the circumference of the outer surface of the ink transfer roller must be an integer multiple of the common divisor of the width of the banknote, otherwise a staggered ink transfer cannot be carried out accurately. Therefore, in the known structure, when the size and the pattern position of the printing product are changed, the offset distance of the offset ink transfer is changed, and the whole set of cylinders including the ink transfer roller, the color mold roller and the number (printing plate) cylinder must be replaced to meet the requirement of the offset ink transfer. The known structure is complex, the application range is limited, the operation cost is high in actual production, and a large amount of time is needed for replacing the whole set of roller, so that the production cost is also increased.

The diameters of the color mold roller 12 and the ink transfer roller 11 are equal to or integral multiples of each other, and in this embodiment, as shown in fig. 1, 2, 3, 5, and 6, the description will be given only by taking the case where the diameters of the color mold roller 12 and the ink transfer roller 11 are equal to each other as an example.
The color mold roller 12 has a central shaft 12 ″ and at least one color mold wheel 12 ' arranged thereon, at least one color module group 120 is arranged on the outer circumferential surface of the color mold wheel 12 ', each color module group is composed of at least two color modules, the shapes, the numbers and the intervals among the color module groups 120 arranged on the outer circumferential surface of the color mold wheel 12 ' are the same, and the shapes and the intervals among the color modules in the same color module group are the same.
The connection manner of the color mold wheel 12' on the central axis of the color mold roller 12 is a common known technology, and is not described herein again.
In the present embodiment, taking the ratio of the diameter of the color module roller 12, the ink transfer roller 11 and the plate cylinder 30 as 1: 2 as an example, it is schematically shown that 3 color module groups 120 are provided on the outer circumferential surface of the color module roller 12', wherein the 3 color module groups are respectively denoted by reference numerals 121, 122 and 123, and each color module group is composed of four color modules a, b, c and d. While the working area of plate cylinder 30 is provided with 3 image-text areas 300, indicated by reference numerals 301, 302, 303, respectively, as shown in figure 2.
When the color mold roller 12 inks the ink transfer roller 11, 3 ink storage areas 110 corresponding to the 3 color module groups 121, 122, 123 on the color mold roller are formed on the ink transfer roller 11, in the figure, the 3 ink storage areas 110 are respectively represented by the reference numerals 111, 112, 113, and each ink storage area 110 is composed of four ink storage blocks a ', b', c ', d'. The 3 image areas 300 on the plate cylinder correspond to the 3 ink reservoirs formed on the ink transfer rollers 11 one by one, and are supplied with ink by the 4 ink reservoirs a ', b', c ', d' in the corresponding ink reservoir 110 in a certain regular turn.
In addition, the surface of the ink transfer roller 11 is made of an elastic material, and the surface of the color mold roller 12 is made of a hard material. The hardness of the elastic material can be 30 degrees to 45 degrees Shore, for example, the elastic material can be a rubber layer or a polyester layer; the hard material may be a nylon plate or a metal plate.
Of course, the ink transfer and inking device of the present invention is not limited to only one set of inking mechanisms 10, and fig. 5 is a schematic structural diagram illustrating an ink transfer and inking device provided with two sets of inking mechanisms 10, so the number of inking mechanisms can be set according to actual needs, wherein the structure and principle of each set of inking mechanisms are the same, and only one set of inking mechanisms is taken as an example for description herein.
A printing apparatus according to the present invention comprises at least a printing unit as shown in fig. 6, and wherein the plate cylinder 30 and the impression cylinder 50 are driven to rotate synchronously by a second drive system.
In one embodiment, the inking system 10 is supplied with ink by a set of independent ink supplies 13, wherein each set of ink supplies 13 may consist of an ink fountain, an ink fountain roller, an ink vibrator, an ink distribution roller, and the like. Each set of inking units 10 comprises an inking unit 13, a colour former cylinder 12 and an ink transfer cylinder 11, which are interconnected in sequence, whereby the inking unit 13 transfers ink to the ink transfer cylinder 11 via the colour former cylinder 12 and from the ink transfer cylinder 11 to the corresponding image area 300 of the plate cylinder 30 with which it is in contact. The inking unit 10 according to the invention is independently driven by a first drive system, see also fig. 1, which can be independently driven by a servomotor 40, while the plate cylinder 30 and the impression cylinder 50 are driven by a second drive system, for example, by another motor (not shown). In this embodiment, the color cylinder 12 is connected to a first drive system, and the color cylinder 12 and the ink transfer roller 11 are driven to rotate synchronously by means of the gears 41 engaging with each other, and the diameter of the color cylinder 12 is equal to that of the ink transfer roller 11.
Of course, fig. 1 is only one specific example, and the servo motor 40 is not limited to driving the color mold roller 12, but may directly drive any of the transfer, distribution and distribution rollers to synchronously drive the other rollers of the inking mechanism through a gear transmission.
When two sets of inking units 10 are provided, as shown in fig. 5, the color former rollers 12, 22 of the two sets of inking units may alternatively be driven synchronously by a separate drive system 40 and the ink transfer rollers 11, 21 of the two sets of inking units 10 may be driven in synchronous rotation by intermeshing gears, respectively. Another possible embodiment is that the two sets of inking mechanisms 10 are driven by two drive systems, such as two servomotors, respectively, and keep the two servomotors rotating synchronously. The control method is well known in the art and will not be described herein.
The working principle of the invention is as follows: the inking unit 10 is driven by a first drive system (e.g., a servo motor 40), wherein the inking unit 10 includes at least an ink supply unit 13, a color mold roller 12, and an ink transfer roller 11 connected to each other in this order, and the color mold roller 12 and the ink transfer roller 11 are rotated in synchronization by the servo motor 40. The ink transfer rollers 11 are each connected to a plate cylinder 30, and the plate cylinder 30 and impression cylinder 50 are driven in rotation by another drive system (not shown).
In operation, ink is transferred by the ink transfer rollers 11 of the inking unit 10 to the respective plate cylinder 30. During a certain period of time, the plate cylinder 30 rotates at a constant speed, and the inking unit 10 moves relative to the plate cylinder 30 at a constant speed in a certain regular manner, so that the inking unit 10 is shifted by a certain distance in each movement cycle relative to the inking position of the plate cylinder 30 in a certain regular manner. Specifically, when the plate cylinder 30 is rotated to the position where its working position (i.e., the position where the image-text area 300 is provided) is opposed to the ink transfer rollers 11, as shown in fig. 2, in this embodiment, when the image-text areas 301, 302, 303 of the plate cylinder 30 are respectively brought into opposed contact with the ink reservoirs a' of the ink reservoirs 111, 112, 113 of the ink transfer rollers 11, the servo motor 40 drives the color mold roller 12 and the ink transfer rollers 11 to rotate synchronously with the plate cylinder 30 at the same rotational speed. When the plate cylinder 30 rotates to the non-working position a (i.e. the position on which no image is provided) opposite to the ink transfer rollers 11, that is, when the ink transfer rollers 11 are in one-to-one contact with the image areas 300 provided on the plate cylinder 30, and after one ink transfer is completed, the plate cylinder 30 rotates to the non-working position a opposite to the ink transfer rollers 11, the servo motor 40 drives the color mold roller 12 and the ink transfer rollers 11 to rotate at a speed greater than or less than that of the plate cylinder 30, so that after one ink transfer cycle is completed by one rotation of the plate cylinder 30, the image areas 300 on the plate cylinder 30 are respectively inked by different ink storage blocks of the same ink storage area 110 on the ink transfer rollers 11 in the next ink transfer cycle, as shown in fig. 3, that is schematically shown after one corresponding ink transfer to the plate cylinder with respect to the ink transfer rollers 11 shown in fig. 2, when the servo motor 40 completes the speed change adjustment, the ink transfer rollers 11 and the corresponding ink transfer positions of the plate cylinder 30 are adjusted to be shifted, and ink is transferred from the ink storage blocks c' of the ink storage areas 111, 112, 113 to the image areas 301, 302, 303.
More specifically, when the ink transfer rollers 11 are in the working area of the plate cylinder 30, they rotate synchronously with the plate cylinder 30 to transfer the ink from the ink storage areas 110 on the ink transfer rollers 11 to the graphic areas 300 provided in the working area of the plate cylinder 30 by cooperating with the plate cylinder 30. When the ink transfer roller 11 is in the non-working area A (i.e. neutral position) of the plate cylinder 30, the rotation speed of the ink transfer roller 11 is different from that of the plate cylinder 30, i.e. stepless speed regulation is performed by the servo motor 40 to drive the color mold roller 12 to perform position dislocation according to a preset interval, and the color mold roller 12 and the ink transfer roller 11 are synchronously dislocated because the color mold roller 12 and the ink transfer roller 11 are connected through a gear and the diameter ratio is 1: 1. For example, in the first cycle (see fig. 2), ink is first transferred by the ink reservoir a' in each ink reservoir 111, 112, 113 of the ink transfer roller 11 for the corresponding image and text areas 301, 302, 303 on the plate cylinder 30. When the plate cylinder 30 is in the working area, the ink transfer rollers are driven by the servo motor 40 to perform variable speed adjustment, so that in the second working cycle, i.e. when the plate cylinder 30 is in the working area again, the ink is transferred by the ink storage blocks in the ink storage areas 111, 112, 113 of the ink transfer rollers 11 except the ink storage block a ', for example, the ink storage block c' in fig. 3 is used as the corresponding image-text areas 301, 302, 303 on the plate cylinder 30.
Fig. 3 is merely an example of the ink reservoir on the ink transfer rollers 11 being offset by three color module spacings with respect to the plate cylinder 30, but is not limited thereto. After the variable speed adjustment of the color mold roller and the ink transfer roller is completed in the non-working area of the plate cylinder, in the next working cycle, ink is transferred for the same image-text area on the plate cylinder 30, and any other ink storage block except the ink storage block a' in the same ink storage area on the ink transfer roller 11 can be an integer from 1 to (x-1) as long as the interval of each variable speed dislocation is an integral multiple of the interval between two adjacent ink storage blocks in the same ink storage area on the ink transfer roller, wherein x is the number of the ink storage blocks in the same ink storage area. Thus, the ink transfer roller 11 can realize dislocation ink transfer once when the printing plate cylinder 30 rotates for one circle, thereby ensuring that the same image-text area 300 on the printing plate cylinder 30 is inked by different ink storage blocks in the same ink storage area 110 on the ink transfer roller 11 every time, ensuring that each image-text area can be fully inked, and correspondingly ensuring the printing quality of the printed images and texts on the securities.
For example: the plate cylinder 30 is operated at 8000 revolutions per hour, and the inking unit 10 is rotated by the first drive system at the same rotational speed as the plate cylinder 30 when the ink transfer rollers 11 are rotated to the working area of the plate cylinder 30; every time the ink transfer roller 11 rotates to the non-working area a of the plate cylinder 30, the inking mechanism 10 is driven by the first drive system (servo motor 40) to operate at 6000 revolutions per hour; after such a working cycle, the position of the ink transfer rollers 11 of the inking mechanism for transferring ink to the plate cylinder is adjusted by the ink reservoir block a 'in the ink reservoir 111 to the ink reservoir block c' in the ink reservoir 111 for transferring ink to the same corresponding image area on the plate cylinder 30, as shown in fig. 2 and 3. Thus, when the ink transfer roller of the inking mechanism rotates for n circles, the plate cylinder rotates for m circles, (of course, in the next movement period, the ink transfer roller of the inking mechanism can also rotate for n circles, and the plate cylinder rotates for k circles.) to ensure that each ink storage block in the same ink storage area 110 on the ink transfer roller 11 is supplied with ink for multiple times by the corresponding color module on the color mold roller 12, then the ink is supplied to the image-text area 300 on the plate cylinder 30, so that the ink supply amount of the image-text area 300 of the plate cylinder 30 is ensured, and the printing quality is ensured.
The present invention thus overcomes the disadvantages of known constructions which require the ratio of the diameter of the plate cylinder to the ink transfer rollers to be non-integer and the circumference of the outer surface of the ink transfer rollers to be an integer multiple of the common divisor of the width of the banknote, otherwise a staggered ink transfer cannot be achieved. The known structure requires the replacement of the whole set of cylinders including the colour mould cylinder, the ink transfer roller and the number cylinder when the products are printed with different number (image-text area) intervals.
The inking mechanism 10 is driven by a first driving system, for example, the servo motor 40 drives the color mold roller 12, and the plate cylinder 30 is driven by another driving system, so that the speed of the ink transfer roller 11 can be flexibly adjusted, the dislocation distance can be adjusted according to the distance B between the color modules in the color module group, and after the ink storage blocks in the same ink storage area on the ink transfer roller 11 are supplied by the color modules on the color mold roller 12 for multiple times, the ink is supplied to the image-text area 300 on the plate cylinder 30, thereby ensuring that the ink supply of the image-text area 300 is sufficient, and improving the quality of the printed product. When the printing product is replaced, namely the distance between the image-text sections on the printing plate cylinder 30 is changed, the size and the distance between the color modules in the color module group on the outer circumferential surface of the color module wheel are only needed to be replaced, and the drive control system is modified to change the preset dislocation distance without replacing the color module roller, the ink transfer roller, the printing plate cylinder and the like, so that the time is saved, the production cost is saved, the production efficiency of printing equipment is improved, and the printing requirements of different printing products can be met.
The plate cylinder 30 in the present embodiment is a relief cylinder, but is not limited thereto.
The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes and modifications that can be made by one skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention. It should be noted that the components of the present invention are not limited to the above-mentioned whole application, and various technical features described in the present specification can be selected to be used alone or in combination according to actual needs, so that the present invention naturally covers other combinations and specific applications related to the invention.
