Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a system for checking that a printing plate is properly mounted at each mounting position when mounting a plurality of printing plates on a printing press for printing.

  For example, in newspaper printing, a plurality of rotary presses and a paper folding machine are connected to form a set of rotary press rows. Then, a plate cylinder for printing each page of a newspaper is mounted on a plate cylinder provided for each rotary press. Recent newspapers are color printed, and it is also universal to use four color separations of C (cyan), M (magenta), Y (yellow) and K (or Q, black) for printing one page There is. In the printing process, it is required to mount a large number of printing plates on the correct plate cylinder and the correct position of each rotary press.

  In the past, the prevention of misplacement of printing plates was solely dependent on inspection before the start of printing visually by the operator and inspection after the start of printing. However, with the increase in the amount of work per worker, the increase in the number of newspaper pages, and the speeding up of the printing process, inspections and inspections relying only on the worker's attention have already reached their limits.

  In addition, it is extremely important to visually confirm the specific content of the plate surface in a completely non-processing plate (a plate that does not need to be subjected to washing with water after printing (exposure), development and gumging processes) which is becoming widespread recently. It is difficult. In other words, it is not clear in the first place what color page of a newspaper a certain printing plate is.

  In addition, daily changes in the number of pages and the layout of newspapers also complicate the situation. Among the rotary presses deployed in printing plants, there are a mixture of those capable of CMYK (or CMYQ) four-color printing and those capable of only monochrome printing of K (Q) color. Not a few. And which page of the newspaper is in color and which page is in monochrome depends on the day, whether it is a morning newspaper or an evening paper. A specific page of a newspaper, for example, six sides (sixth page) is not always in color, and is not always in monochrome. Since color pages can only be printed by a color-printable rotary press, the color / monochrome paper configuration of each page of a newspaper also makes it necessary to change the rotary press used to print each page. It is not guaranteed that the rotary presses for printing the six sides are always the same. Therefore, even for skilled workers, it is not always easy to fit all the printing plates on the plate cylinder without error each time.

  Therefore, the work of mounting the printing plate on the plate cylinder by printing the information of the mounting position on each of the plurality of printing plates using aqueous ink so as to be clearly and easily visible with the naked eye It has become common practice to let people know the mounting position of each printing plate correctly to prevent erroneous mounting. Printing with water-based ink is washed away and removed by dampening water applied to the printing plate when the rotary press, which is an offset printing press, is activated (see the following patent documents).

  In newspaper printing, printing may be continued by replacing only some pages. Typically, this is a local version, that is, replacement of a page whose page content differs depending on the region or prefecture where the newspaper is read, or sudden replacement of the page by obtaining emergency news or the like. That is, once all printing plates have been mounted on the plate cylinder and printing is started, there is a task to exchange some of them for other printing plates as needed. Needless to say, such plate exchange needs to be carried out without error.

  The present invention makes it easy to ensure that a printing plate has been properly mounted when it is time to replace a part of a plurality of printing plates mounted at each mounting position of a printing machine with another printing plate.

  One embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an overview of the entire newspaper printing system in the present embodiment. This system includes a rotary press 3, a laser processing machine 4 for making a printing plate 7 mounted on the rotary press 3 and used for printing, and an inkjet for printing additional information 71 and printing plate identification information 72 described later on the printing plate 7. The printing plate 5 is a printer, the control computer 0 controls the rotary press 3, the CTP (Computer-To-Plate) server computer 6 controls the laser processing machine 4 and the printing unit 5, and the plate cylinder 311 of the rotary press 3 The information processing terminal 1 possessed by the worker who wears 7 and the inspection computer 2 which determines whether the printing plate 7 is properly mounted on the rotary press 3 are components.

  As shown in FIG. 2, the rotary press 3 is, for example, a tower-type known one in which four rotary presses 31 respectively responsible for printing four colors of CMYK (or CMYQ) are stacked. Each rotary printing press 31 is an offset printing press, and the printing ink attached to the printing plate 7 wound around the plate cylinder 311 is transferred to an intermediate transfer member 312 such as a rubber blanket, and then the paper 9 as a printing object Print on The plate cylinder 311 and the intermediate transfer member 312 of each rotary printing press 31 are disposed to face the front and back sides of the paper 9, and the printing plate 7 for printing on the front side and the back side are printed on each of the plate cylinders 311. The plate 7 for printing is mounted. The printing plate of one printing plate 7 has an area for two pages of newspaper, and the printing plate 7 for two sheets, that is, four pages of newspaper is mounted on one printing cylinder 311 of the rotary printing press 31. One tower-type rotary press 30 prints four pages on the front side of the paper 9 and four pages on the back side. That is, it is possible to print in full color the paper of eight pages conveniently on both sides. By combining five such tower-type rotary presses 30 into one unit, it is possible to print newspapers of up to forty pages. However, some of the plurality of rotary presses constituting one unit may be a rotary press dedicated to monochrome printing that can not perform color printing. Such a rotary press comprises only a single rotary press 31 for the K (Q) color. The paper 9 continuously printed by the rotary press 3 is cut by the paper folding machine 32 and then folded into pieces of newspaper. Thus, in the printing plant, a plurality of units in which the rotary press 3 and the paper folding machine 32 are connected are provided.

  The CTP server computer 6 controls the preparation of the printing plate 7 by the laser processing machine 4 and the control of the printing process such as printing plate identification information to the printing plate 7 by the printing apparatus 5. The CTP server computer 6 controls the laser processing machine 4 to receive information on the plate surface of each page of the newspaper to be printed from the outside and form the plate surface on the plate which is the material of the printing plate 7. Perform laser processing.

  Furthermore, the CTP server computer 6 identifies additional information 71 indicating which page of which newspaper and which page of which date the printing plate 7 completed through laser processing is and the completed printing plate 7 The printing apparatus 5 is controlled to execute printing on the printing plate 7 in order to display the printing plate identification information as an identification identifier on the plate surface of the printing plate 7. As illustrated in FIG. 3, the additional information 71 is printed in the form of a character string that can be visually recognized by the operator. The additional information 71 plays the role of making the operator recognize the mounting position of the plate cylinder 311 in the rotary press 3 to which the printing plate 7 should be mounted. On the other hand, the printing plate identification information is printed in the form of a code 72 of a format readable by the information processing terminal 1 used by the worker, for example, a two-dimensional code (in particular, QR code (registered trademark)) or a bar code. . The printing plate identification information is used by the replacement surface inspection system of the present embodiment to detect an error in the mounting of the printing plate 7 on the rotary press 3. The ink used by the printing device 5 for printing is an aqueous ink that can be washed away with dampening water applied to the plate surface of the printing plate 7 in the rotary press 3.

  As a supplement to the additional information 71 in the illustrated example, the “D version” indicates the destination of the local version, that is, a page intended for readers of which region or prefecture. As a specific example, "D version" is a local version page for Shiga blocks, and "E version" is a local version page for Aichi blocks. That is, even if it is "2 pages (2nd page)" of "the evening paper" of the same "22nd", the contents of the paper differ depending on the destination, and therefore the printing plate 7 used for printing this page is different. is there. After printing the evening paper for Shiga block, if you continue to print the evening paper for Aichi block, replace plate 7 for printing the page with the one for "D" and the one for "E" A need arises. “Self 11P” indicates a unit of the rotary press 3 on which the printing plate 7 should be mounted.

  The hardware resources of the control computer 0 and the CTP server computer 6 are the same as those of the computer 2, and therefore the description thereof is omitted here.

  The function of each part of the replacement surface inspection system of the present embodiment will be described in detail. The plate identification information acquisition unit 101 of the information processing terminal 1 is a plate identification for identifying the plate cylinder 311 attached to the plate 7 already mounted or to be mounted on the plate cylinder 311 of the rotary press 3. Get information. In the present embodiment, printing plate identification information is printed in advance in the form of a two-dimensional code 72 or the like using water-based ink on the plate surface of the printing plate 7 mounted on the plate cylinder 311. The operator shoots the two-dimensional code 72 and the like with the camera sensor 1 h mounted on the information processing terminal 1 owned by the operator. Thereby, the information processing terminal 1 reads the printing plate identification information, and further transmits the printing plate identification information to the inspection computer 2 through the LAN in the printing factory.

  The mounting position identification information acquisition unit 102 of the information processing terminal 1 acquires mounting position identification information identifying a mounting position at which the printing plate 7 in the rotary press 3 is already mounted or to be mounted. As described above, one unit of the rotary press 3 of the present embodiment is equipped with four tower-type rotary presses 3 and one tower-type rotary press 3 has four rotary presses 31 and one The base rotary printing press 31 is provided with two plate cylinders 311, and one plate cylinder 311 is equipped with two printing plates 7. Therefore, one tower type rotary press 3 can be equipped with at most sixteen printing plates 7 and at most one sixty-four printing plates 7 in one unit. In other words, 64 mounting positions for mounting the printing plate 7 exist in one unit. If a plurality of units are deployed in the printing plant, the number of mounting positions of the printing plate 7 increases in proportion to the number of units. As shown in FIG. 7, in the present embodiment, radio waves or electric waves or waves may be attached to each of two mounting positions of one plate cylinder 311 in the vicinity of the mounting position (which may be directly above or below). A beacon 8 capable of transmitting an electromagnetic wave is installed. Each beacon 8 transmits mounting position identification information, which is an identifier for identifying a mounting position corresponding to the beacon 8, toward the vicinity of the mounting position in the form of a radio wave or an electromagnetic wave signal. When the beacon 8 is an RFID card or chip, the reach of the signal, that is, the communicable distance is relatively short. The worker receives this signal with the NFC reader or RFID reader 1 l mounted on the information processing terminal 1 owned by the worker. Thus, the information processing terminal 1 receives the mounting position identification information, and further transmits the mounting position identification information to the inspection computer 2 through the LAN in the printing factory.

  It supplements regarding the operation at the time of acquiring printing plate identification information and mounting position identification information. The operator goes to any mounting position of the plate cylinder 311, and on the spot, the irradiation range of radio waves or electromagnetic waves from the beacon 8 attached to the mounting position (this mounting range, of course, the mounting position) In the vicinity of)). In the case where the beacon 8 is an RFID card or chip, the irradiation range 81 of radio waves or electromagnetic waves may be an extremely short distance from the beacon 8, in which case the worker brings the information processing terminal 1 into contact with the beacon 8. It is necessary to hold the beacon 8 so as to make the contact almost in contact.

  At this time, as a function of the mounting position identification information acquisition unit 102, as shown in FIGS. 8 and 9, the display 1i of the information processing terminal 1 receives the NFC reader or the RFID reader 1l built in the information processing terminal 1 An image 11 is displayed that suggests the position of the antenna. The image 11 appears at a position overlapping the receiving antenna of the NFC reader or the RFID reader 11 when the information processing terminal 1 is viewed from the direction perpendicular to the display 1 i. The worker holds the information processing terminal 1 so that the image 11 is located directly below the beacon 8, so that the receiving antenna of the NFC reader or the RFID reader 1 l is properly within the irradiation range 81 of radio waves or electromagnetic waves from the beacon 8. Can be positioned.

  In addition, when the information processing terminal 1 succeeds in receiving the attachment position identification information transmitted from the beacon 8, as a function of the attachment position identification information acquisition unit 102, as shown in FIG. 10, the light emitting device 1k of the information processing terminal 1 However, while irradiating the visible light 12 toward the imaging target area of the camera sensor 1 h automatically, imaging with the camera sensor 1 h and recognition processing of the two-dimensional code 72 and the like are executed. The visible light 12 not only becomes illumination light illuminating the plate surface of the printing plate 7 to be photographed and the two-dimensional code 72 printed on this, but also the area of the object to be photographed by the camera sensor 1 h It also has the effect of making workers visually recognize. The light emitting device 1k may emit light to project the reticle (cross hair) 13 serving as an aim of the imaging target area onto the plate surface of the printing plate 7. The operator holds the information processing terminal 1 over the beacon 8 and immediately thereafter performs a series of operations such as photographing the plate surface of the printing plate 7 in front of the user, thereby identifying the mounting position according to the mounting position where the operator is located A pair of information and plate identification information related to the plate 7 to be mounted at the mounting position can be obtained, and the pair of information can be transmitted to the inspection computer 2.

  Incidentally, in the present embodiment, as shown in FIGS. 7 to 10, the mounting position identification information and the printing plate identification information are acquired before the printing plate 7 is completely wound around the plate cylinder 311. The rotary press 3 is provided with a mechanism for automatically winding and fixing the printing plate 7 around the plate cylinder 311. The operator uses the information processing terminal 1 to obtain the mounting position identification information and the printing plate identification information, and the mounting position where the printing plate 7 which is about to be mounted on the printing drum 311 (not yet wound on the printing drum 311) is correct After confirming that the printing plate 7 is located, the above-described mechanism is activated to wind and mount the printing plate 7 on the plate cylinder 311.

  Note that the information processing terminal 1 captures a character string of the additional information 71 printed in advance on the plate surface of the printing plate 7 through the camera sensor 1 h, and reads this by OCR (Optical Character Recognition), thereby It is also possible to obtain plate identification information that identifies the plate 7.

  Moreover, as shown in FIG. 9 and FIG. 10, mounting position identification information for identifying the mounting position can be read by the information processing terminal 1 beside each mounting position of the rotary press 3 of the present embodiment. It is attached in the form of code 313 in the form. Under a situation where reception of the mounting position identification information transmitted from the beacon 8 is not successful, the mounting position identification information for identifying the mounting position is acquired by photographing the code 313 with the camera sensor 1h of the information processing terminal 1. You can also.

  The collation data storage unit 201 of the inspection computer 2 utilizes the required storage area of the main memory 2b or the auxiliary storage device 2c, and for each mounting position of the rotary press 3, as illustrated in FIG. The printing plate identification information for identifying the printing plate 7 to be mounted is stored. This information stored in the collation data storage unit 201 is collation data used to determine whether or not the correct printing plate 7 is mounted at each mounting position of the rotary press 3, and identifies the mounting position of the printing plate 7 It is a combination of mounting position identification information to be performed and printing plate identification information for identifying the correct printing plate 7 to be mounted at the mounting position. However, for the mounting position where the printing plate 7 is not mounted, the printing plate identification information is empty (or information indicating that the printing plate 7 does not need to be mounted). The verification data is provided, for example, from the CTP server computer 6 or the control computer 0 through the LAN. The inspection computer 2 receives this and stores it in the collation data storage unit 201.

  When the time to replace a part of the plurality of printing plates 7 mounted at each mounting position of the rotary press 3 with another printing plate 7 comes, the verification data updating unit 202 of the inspection computer 2 Printing plate identification information for identifying a new printing plate 7 after replacement is stored in the collation data storage unit 201 as printing plate identification information relating to the printing plate 7 to be mounted at the mounting position where the printing plate 7 needs to be replaced. Let it be stored. For example, when a part of a plurality of printing plates 7 is replaced with another printing plate 7, for example, after printing of a newspaper targeted to a certain destination is completed, a newspaper continuing to target another destination This is the case when printing a page or when suddenly replacing a page by obtaining emergency news etc. When printing a newspaper with different destinations, the printing plate 7 of the page with different contents of the page must be replaced for each destination, but the printing plate 7 of the page with common contents of the page is replaced regardless of the destination There is no need to Even when the page is suddenly replaced, only the printing plate 7 for printing the page to be replaced needs to be replaced. The collation data updating unit 202 relates to a mounting position at which the printing plate 7 needs to be replaced among the collation data used to determine whether or not the correct printing plate 7 is mounted at each mounting position of the rotary press 3. By updating the printing plate identification information, it is possible to determine whether or not the printing plate 7 is mounted at an appropriate mounting position when replacement of a part of the printing plate 7 is performed.

  The verification data update unit 202 updates the verification data before the plate 7 is exchanged. The replacement surface data, which is data for updating the verification data, includes mounting position identification information for identifying the mounting position at which the printing plate 7 is to be exchanged, and the printing plate 7 (newly attached) newly mounted at the mounting position. It includes a set of plate identification information to identify. The substitute plane data is obtained, for example, from the CTP server computer 6 or the control computer 0 through the LAN. The verification data update unit 202 of the inspection computer 2 receives this, stores it in the verification data storage unit 201 in association with the mounting position identification information identifying the mounting position where the printing plate 7 is exchanged, that is, the printing plate 7 is exchanged The printing plate identification information relating to the mounted position is rewritten.

  It is necessary for the inspection computer 2 to actually acquire the surface data from the CTP server computer 6 or the control computer 0 before the need to replace the printing plate 7 (for example, printing of a newspaper intended for another destination) All printing plates 7 (used for the printing of a newspaper intended for a certain destination) necessary to carry out the printing process in the stage of printing a newspaper intended for a certain destination prior to It may be the timing at which it is determined that the printing unit has been mounted at the correct mounting position, the timing after that, that is, the timing when the printing process of the previous stage is started, or the timing when the printing process of the previous stage is finished. As described later, the subject that determines that all the printing plates 7 have been mounted at the correct mounting position is the inspection computer 2, so when the determination is completed, the inspection computer 2 executes the CTP server computer 6 or the control computer 0. The CTP server computer 6 or the control computer 0 that has received the request can send back the replacement surface data to the inspection computer 2. Alternatively, CTP server computer 6 or control computer 0 is monitoring the start or end of the printing step of the previous stage, and when CTP server computer 6 or control computer 0 starts or finishes the printing process, replacement data from the CTP server computer 6 or control computer 0 Can be transmitted to the inspection computer 2.

  The determination unit 203 of the inspection computer 2 includes the plate identification information acquired through the plate identification information acquisition unit 101 of the information processing terminal 1 and the mounting position identification information acquired through the mounting position identification information acquisition unit 102. It is determined whether the pair matches the plate identification information for each mounting position read out from the collation data storage unit 201. That is, it is determined whether the printing plate 7 to be mounted at the mounting position of the plate cylinder 311 with the rotary press 3 is the correct printing plate 7 to be mounted at the mounting position. As described above, the operator uses the information processing terminal 1 to mount position identification information for identifying the mounting position of the rotary press 3 and a plate identification for identifying the printing plate 7 to be mounted at the mounting position. Perform an operation to sequentially read information. The information processing terminal 1 having received this operation acquires a pair of mounting position identification information relating to one mounting position and printing plate identification information relating to one printing plate 7, and transmits it to the inspection computer 2. . The inspection computer 2 that has received the pair of mounting position identification information and printing plate identification information is associated with the mounting position identified by the received mounting position identification information, which is defined in the collation data stored in the collation data storage unit 201. The printing plate identification information (to identify the printing plate 7 to be mounted at the mounting position) is read out. Then, this is compared with the received plate identification information. If the two match, the printing plate 7 which is about to be mounted at the mounting position where the operator is currently located is the proper printing plate 7, otherwise the printing plate 7 is mounted at the wrong mounting position It is the incorrect printing plate 7 which is going to be done. The inspection computer 2 transmits the result of the above determination to the information processing terminal 1 through the LAN. Each time determination section 203 receives a pair of mounting position identification information and printing plate identification information from information processing terminal 1, determination section 203 executes determination and sends the result back to information processing terminal 1.

  The determination result output unit 103 of the information processing terminal 1 outputs the determination result by the determination unit 203 of the inspection computer 2 in a manner to appeal to the operator's sight, hearing or touch. Specifically, if the judgment result that the information processing terminal 1 has received from the inspection computer 2 is that the printing plate 7 that is about to be mounted at the mounting position where the operator is currently located is correct, it is appropriate. Information indicating that it is displayed on the screen of the display 1i, outputting a specific sound or sound indicating that it is appropriate from the audio output device 1j, or a light emitting device 1k with a specific pattern indicating that it is appropriate Is notified, the operator is notified of the determination result by not turning on, turning off, blinking or blinking, or not vibrating (or vibrating) the vibrator mounted on the information processing terminal 1.

  On the other hand, if the judgment result indicates that the printing plate 7 which is about to be mounted at the mounting position where the operator is currently located is incorrect, the display 1i shows information indicating that it is incorrect. The voice output device 1j displays a specific sound or voice indicating that it is improper, or the light emitting device 1k is lit, extinguished, blinks, or in a specific pattern indicating that it is improper. By blinking or vibrating the vibrator (or not vibrating), the operator is notified of the determination result promptly. An operator who senses that the printing plate 7 in the mounting position in front of the eye is an incorrect printing plate 7 to be installed erroneously removes the printing plate 7 and substitutes the appropriate printing plate 7 for the installation. Do the work of mounting at the position. Then, the mounting position identification information and the printing plate identification information are read again using the information processing terminal 1, these are transmitted to the inspection computer 2, the determination by the determination unit 203 is executed, and the determination in the information processing terminal 1 Receive and know the results.
