describe

Field invention

The present invention relates generally to a printing system and method, and more particularly to a printer for forming a printed image on the surface of a printing device. Although the present invention is particularly suitable for rotary printing gas cylinders, the present invention is not necessarily so limited, but can be applied to other fields.

Background invention

Some existing printing systems use printing plates. This area is printed as the above area, and printing is not allowed. The reason why there are two different levels is the so-called "relief" printing field. The amount of relief required depends largely on the material to be printed. There is almost no change in the medium, the demand for controllable thickness, and some uncertain reliefs, but more relief materials are needed. An example of a high-precision medium is a magazine paper printing grade network. Representatives of less accurate media, such as corrugated board printing and feeding utensils. In any case, the necessary relief is not great. Corrugated board is usually embossed with 1mm (0.040 ").

Rotary press, there are several ways to create these types of printing cylinders in printing and non-printing fields. One way is to use processing tools and machine tools instead of gas cylinders. Another method is to use the printing plate to form a unit photography form, glue the carrier table, and then install the steel plate and the carrier table in a cylinder that is sufficiently smaller than the expected printing diameter account thickness. The mounting roller provided by the mounting plate, paper and carrier is called printing blanket. The latter system is a common printing machine for manufacturing corrugated boxes.

In any case, the roller or blanket must be installed and removed every printing job. They must clean up and store print jobs between runs. Changing the image to be printed involves changing the drum or blanket.

Different thicknesses, materials used to make the blanket, plates, adhesives and stages may lead to great differences in the overall thickness of the blanket, resulting in different ideal printing cylinders.

Objects and advantages of the present invention

Object of the Invention The present invention provides a new method and apparatus for forming a printing machine with a printing surface, and overcomes the above disadvantages.

Another object of the present invention is to provide a new method and apparatus for in-situ forming a printing surface on a printing machine or other printing equipment. Listed here are methods and instruments that can be used to quickly replace the printing surface of a printing machine or other printing parts printing machine without disassembling the cylinder.

Another object of the present invention is to provide such a method and apparatus for forming a printing surface, using electronic images in an automatic manner, for example, through a computer image processing system, and by using electronic images for equipment, buildings and printing surfaces.

Another object of the present invention is to provide the method and apparatus as described above, and it can also be applied to traditional printing apparatus, such as an apparatus using a rotating printing cylinder.

Other advantages, the invention includes the following contents:

The print job can start as soon as possible. The ideal method of electronic image printing is not to wait for the roller blanket to be ready, usually in the distance.

There is no need to store and preserve gas cylinders or blankets.

There is no loss in changing the continuous printing operation of the same job.

You can change printing, quickly stop printing, delete some plates and replace them with new printing. So in the long run, many small groups of products can produce different materials or instructions, as long as the basic parameters have not changed. In the case of box manufacturing, in the long run, boxes of specific products and groups of these boxes can be printed to show different colors or models of product packaging.

The system of the invention can be fully automated, thus avoiding the unpredictable delay of the manufacturing process and the damage causes of manual installation and disassembly of gas cylinders and blankets.

In a possible configuration with four printing stations, all printing can use a four-color processing method, in which all colors are the four basic colors of printing spots, usually cyan, magenta, yellow and black. With the invention, the printing operation of ink does not need to be changed.

Even if all the components of the traditional blanket are tightly tolerated, the combination of total thickness may vary greatly. By establishing the printing surface at a suitable position and shaping it when necessary, the printing surface can be particularly concentric to achieve optimal printing.

The first choice of the summary embodies the present invention.

For convenience of explanation, the methods and machines described below are used to print corrugated boards and make squares. It should be understood that the present invention can be implemented using a printing surface with "relief" in any printing mode or machine.

In a preferred form, the method steps include the construction and configuration of in-situ printing components such as printing cylinders and improved printing surfaces. Surface configuration is the best way to print the required image on the board meeting. The deposition surface of the automatic "rapid prototyping" device or "melting deposition simulation device" is pre-configured and connected to the equipment according to the computer image processing system provided by the electronic image. In order to change the printing surface, the next printing job needs to print different pictures. The first surface is removed from the printing cylinder in any suitable way, such as scraping, grinding, cutting, etc.

Using the above method, the printing machine will include:

The diameter of the printing cylinder is less than twice the expected printing diameter. The surface printing cylinder of the material allows the printing surface material to be improved to conform to it.

The traditional impression cylinder is the printing of cylinder storage materials, such as corrugated board and contact surface printing.

Traditional systems transmit forms through a printing press.

Traditional deinking systems use a controlled amount of ink to print their surrounding surfaces. For example, only one such system is a flexible, grave-changing blade system.

According to a preferred form of the present invention, the bracket is used to store the materials of the mobile device in the front and rear edge printing cylinders. The other carriage has tools for machining, scraping, cutting and/or grinding the printing surface to delete it at the end of the printing operation, and prepares the printing cylinder to receive the next printing surface for the next printing operation. If necessary, it can also be used to provide uniform and concentric surface printing after the printed surface of the decorative material is deposited. This may include debris removal devices, such as vacuum systems.

If it is a thermoplastic material, the cylinder or material can be heated to help remove the material. In addition, the printing surface can be concentric, and if necessary, heating rollers can replace processing, cutting, scraping and grinding equipment.

expand on

When referring to the current drawings, it is shown in detail that the instrument includes a machine for illustration purposes only, which constitutes a preferred method for implementing the present invention. The printing machine is used to print a photo of 10, such as corrugated board, which is the surface printing cylinder 12 of the multi-roller rotary transport platform 10, generally designated as 20. On the balance sheet 10, volume 12, the cover 14 is held to close the space generated in vacuum. Specifically, it is shown that the impression cylinder 16 is located in the portion of the light shielding plate 14 in the printing cylinder 20 to provide contraction across the table, and this is through the printing cylinder 20 that receives the image. Although in a specific embodiment, the form 10 is shown as being conveyed to the printing cylinder 20, it should be understood that in other embodiments not shown, the balance sheet may be conveyed to a position lower than the printing cylinder 20. Among the flexible materials, impression cylinder 16 can be partially summarized. Similarly, the present invention is not necessarily limited to printed corrugated board, but will be applicable to other balance sheets or materials for flexible web-to-print.

Except for the printing cylinder 20 formed on the printing surface proposed on 22nd (which will be described according to the present invention), the text printing cylinder on May 20th is conventional and needs no further description, and this cylinder is a well-known technology ... However, the 20-cylinder diameter printing option for printing the account surface on 22nd will be described. In addition, the surface printing cylinder 20 must be made of a material so that the printing surface 22 can adapt to it. Therefore, in the embodiment where the surface material is printed with thermoplastic, the surface printing cylinder 20 must conform to the thermoplastic material so that it can conform to it.

The ink is supplied to the printing cylinder in any suitable or conventional manner, for example, by extending 24 the ink from the head to extend 26 the ink on the surface of the roll call 24. The first one 26 is mounted on a beam 28.

In the preferred embodiment, on 22nd, the surface printing cylinder deposited on the printing surface is continuously located on single layer or multi-layer on 20th, and the other 30 cylinders are usually designated by the melting deposition simulation device, including 36 deposition heads and movable articles, which rise along the surface printing cylinder 20 to deposit flowable materials, preferably thermoplastics, on the surface of one or continuous layers. When depositing a substance on the printing cylinder 20, the printing cylinder turns on its axis 2 1 servo drive motor to achieve the ideal area position on the deposition head 36. The deposition head 36 is positioned facing the printing cylinder 20 by a lead screw 35, which is a servo-driven motor. A computer image processing system for controlling the output of the printing cylinder 20 and the deposition head 36. For example, by proposing Stratasys, one such fused deposition simulation device can be used. Another similar device can be used as a three-dimensional system of ACTUA 2 100 multi-jet simulator. This device is also called "rapid prototyping" device. The material 36 compresses the head and quickly strengthens the deposited printing cylinder 20. The electronic image products for controlling and managing the shape of the deposited substance are preferably connected to the input of operation, equipment and 30 rollers through a computer image processing system. In the field of corrugated board, the printed 10 corrugated board is 1 mm (0.040 inch) relief, that is, the 22nd printing surface protrudes 1 mm or 0.040 inch from the surface printing cylinder 20.

Specifically, the printing member 20 is shown as a rotary printing cylinder, and 36 deposition heads will be mounted on a carriage 33, which in turn is slidably mounted on a parallel guide rail 34 to move along the longitudinal direction of the guide rail and print the cylinders 20 and 34, and the movement is carried out by a lead screw 35. As shown in the figure, the guide rail of three or four hectares is appropriately elongated to support the fixed channel 32. 1 。

As mentioned above, the printing surface 22 is adapted to the printing cylinder through the deposition head 36, which has been deactivated and the printing cylinder 20 is ready for printing. The deposition head 36 is printed at 22 off the printing surface or radially or axially. After a specific printing job is completed, it is desirable to apply the printing cylinder 20 with a different configuration to the printing surface on 22nd. The original printing surface on No.22 is removed in any suitable way, such as scraping, grinding or cutting from the surface of the printing cylinder 20 until the latter is restored to its original diameter. Specifically, the tool 46 is shown with the printing surface 22 removed and mounted on a conveyor 47, which in turn is mounted on a slidable parallel guide rail with 44 fixed extensions to support 42 channels to expand the printing on the edge of the drum. The carriage 47 is a lead screw 45 along a rail 44, and the rail 44 is a driving motor. When machine printing, the position of the deletion tool 46 is printed radially or axially from the ground 22. If the tool 46 is also used to decorate the printed surface after the 22nd deposition, it must have two radial positions. The tangential surface cylinder 20 is removed and the tangential printing surface 22 is finely adjusted. Although the tool 46 is shown as a grinder, scraping, cutting or any other suitable tool may be used in its place. In addition, on May 20th, the printing cylinder may also be heated to help eliminate the printing surface 22 formed of thermoplastic materials.

In the tool 46 where the previous printing surface 22 has been deleted, the deposition head 36 can then start the next printing job to apply a new printing surface 22 to the printing cylinder 20. In some cases, it is preferable to delete only a part of the printing surface 22 and modify the deposition head 3 in this respect, which makes it easy to control and remove the deposition head 36 by a suitable tool 46.

As can be seen from the above, it is effective to cancel the printing surface 22 in advance and apply a new printing surface without shutting down or disassembling the printing cylinder 20 or the printing equipment in the relevant area. The precise shape can also be quickly given to the printed surface by the computer image processing system and related deposition equipment 36 on 22nd.

Although the preferred embodiments of the present invention have been proved as described above, it should be understood that the present invention is not limited to these specific embodiments, but is an additional requirement indicated in the present invention showing its scope.
