[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing plate which is automatically printed on a printing plate by a fully automatic printing machine and then developed, and the pattern area of the printed printing plate subjected to the developing process is developed. The present invention relates to a printing plate automatic processing apparatus for automatically measuring a rate and automatically processing a series of steps until finishing as a final printing plate used for printing.

[0002]

2. Description of the Related Art Recently, a printing plate is automatically baked by a fully automatic printing machine, the baked printing plate is developed, and the pattern area ratio of the baked printing plate subjected to the developing process is determined. 2. Description of the Related Art A printing plate automatic processing device that measures a picture area ratio measuring device and automates a series of processes until finishing as a final printing plate used for printing is being developed.

The picture area ratio measuring device is a picture pattern defined as a ratio of an area of an image portion to an area of a divided area of a printing plate divided for each ink key for adjusting an ink supply amount to printing paper. It measures the area ratio.

That is, in FIG. 9, reference numeral 1 denotes a rectangular printing plate, and 2 denotes ink keys for adjusting the amount of ink supplied to printing paper (not shown). The printing plate 1 is divided according to the arrangement direction of each ink key 2,
n indicates each divided area. 3 is a picture. Each pattern area ratio is determined by whether or not the image area of the pattern 3 printed in each area of each of the regions 1 to n has or not. For example, the area of the i-th divided region Is b, and the area of the image portion of the picture 3 in the i-th divided area is a
Then, the i-th picture area ratio S is defined by a / b.

[0005] The opening of the ink key 2 is set for each pattern area ratio, and the amount of ink supplied to each of the divided areas 1 to n of the printing plate 1 is set according to the opening.

[0006]

The printing plate 1 is roughly classified into a positive PS plate, a negative PS plate, a waterless lithographic plate, and the like. Although it is possible to perform printing, it is necessary to change the developing solution and developing device according to the type of development. In the conventional printing plate automatic processing apparatus, when only one fully automatic printing plate machine is installed, the same type of printing plate continuously flows to the developing process and the like. The operator switched between printing and discharging, and discharged printing plates that could not be developed.

However, in the automatic printing plate processing apparatus, a plurality of fully automatic printing machines are installed in the automatic printing plate processing apparatus because the processing capacity of the developing process and the like is larger than the processing capacity of one full automatic printing machine. Is strongly desired. In this case, if a plurality of types of printing plates are mixed and flow to the development process, etc., the switching by the operator is not in time, the switching work load of the operator is large, and the printing time of the plurality of types is occupied. It is difficult to process a plate with a printing plate automatic processing device, and even with a printing plate automatic processing device having a plurality of fully automatic printing machines, processing at a time is limited to the same type of printing plate. Was. Therefore, for other types of printing plates, a dedicated printing plate automatic processing device is separately installed, and for other types of printing plates, workers are manually baking, etc. There were problems such as a large load.

Further, when a printing plate automatic processing device is provided with a pattern area ratio measuring step, data such as a printing plate management number, a printing machine on which the printing plate is to be set, and the number of ink keys are required. In a conventional printing plate automatic processing apparatus, when only one fully automatic printing plate machine is installed, printing plates of the same lot continuously flow to the development process and the like, so that the number of printing plates and the like are managed, There was no problem if the data was allocated in order. However, when multiple fully automatic printing machines are installed in the automatic printing plate processing device, the printing plates baked by each fully automatic printing machine are mixed and transported to the pattern area ratio measurement process. There is a problem that it is not possible to determine which printing plate corresponds.

Further, when a plurality of fully automatic printing machines are installed in the automatic printing plate processing apparatus, a label sticking device or the like which is an identifier providing means for providing an identifier to the printing plate is provided for each fully automatic printing machine. Had been set up. This is because it is not possible to identify on the conveyance means which printing machine has been discharged from the printing press, and the printing press can only determine which printing press has been ejected from the printing press within the printing press or immediately after discharging from the printing press. This is because it is not possible to identify whether the paper has been discharged from the fully automatic breeding machine. But in that case,
It is necessary to install a large number of identifier providing means, and the equipment efficiency is low. The provided identifier needs to have high resistance to a developing solution, a brush, etc. during the developing process, and the cost is high, and the means are limited. And so on.

Further, the printing plate 1 includes FIGS.
As shown in FIG. 2, positioning pin holes 4, 4 are formed. These pin holes 4, 4 are used when the printing plate 1 is set on a so-called stencil printing machine including a fully automatic stencil printing machine and a pattern is printed. This is used when setting a printing plate on a printing machine (not shown) and performing plate bending for setting the printing plate on the printing machine.

However, for example, in a printing machine for a sheet-fed printing press, the pin holes 4, 4 are inserted into the pins so as to be spaced apart in the horizontal direction perpendicular to the conveying direction X of the printing paper, and the printing plate is printed. In the printing press for a rotary press, the printing plate is set by inserting the pins into the pins so that the pin holes 4, 4 are spaced apart in the vertical direction which is the transport direction X of the printing paper.
Therefore, as shown in FIG. 10, when printing the same pattern 7 as the pattern 6 printed on the printing plate 5 used for a sheet-fed press on a printing plate 8 used for a rotary press, It is necessary to change the positional relationship of the pattern 3 with respect to the pin holes 4, 4 by 90 degrees between the printing plate 5 used and the printing plate 8 used for the rotary press.

As described above, the direction in which the printing plate is set may vary depending on the type of printing press, manufacturer, and the like.
When the printing plate 5 baked by the fully automatic printing machine is transported as it is and developed to measure the pattern area ratio, the ink plates 2 arranged in a direction crossing the transport direction of the printing paper are used. When the picture area ratio of each divided area is matched, the printing plate 8 printed by the fully automatic printing machine is transported as it is, developed, and the picture area ratio is measured. When the printing plate 8 is set on the press, the ink key 2 does not fit in each divided area of the picture area ratio as shown in FIG. 12, which causes a trouble in printing.

The present invention has been made in view of the above circumstances, and an object of the present invention is to automate a process from printing of a pattern on a printing plate to development of the printing plate by a plurality of fully automatic printing machines. In the automatic printing plate processing system, we provide a printing plate automatic processing unit that can automate the processes from printing of a pattern on the printing plate to development of the printing plate and measurement of the pattern area ratio even if multiple types of printing plates are mixed. Is to do.

[0024]

According to the present invention, a plurality of types of printing plates are successively printed by a plurality of fully automatic printing plates of the printing plate automatic processing apparatus. The baked printing plate is conveyed to the developing step by the first conveying means. However, a printing plate of a type which cannot be developed in the developing step in the printing plate automatic processing device is identified by the printing plate discharge control means, The printing plate is discharged by a printing plate discharging unit provided in one transport unit.

Further, according to the present invention, the printing plate identification control means identifies which fully automatic printing machine the printed printing plate has been printed, and sends this identification information to the pattern area ratio measuring means. The developed printing plate transported to the picture area ratio measuring unit by the second transporting unit specifies the fully automatic printing machine that has performed printing based on the identification information, and specifies a necessary printing plate management number. The data of the printing press on which the printing plate is to be set, the number of ink keys, and the like are selected, and the pattern area ratio is measured.

Furthermore, according to the present invention, the positional relationship of the pattern in the fully automatic printing machine with respect to the printed printing plate is determined by setting the printed printing plate in the printing machine in relation to the pattern area ratio measuring step. When the ink plate conforms to the arrangement direction of each ink key, the printed printing plate is transported to the pattern area ratio measurement step while maintaining the transported state transferred from the fully automatic printing machine, and the pattern is printed on the printed printing plate. When the printing plate that has been baked is set in the printing machine due to the positional relationship in the fully automatic printing machine and the pattern area ratio measurement process, the printing plate that has been printed is rotated so that it matches if it does not match the arrangement direction of each ink key. Then, it is transported to the picture area ratio measuring step.

Furthermore, according to the present invention, a plurality of types of printing plates are successively printed by a plurality of fully automatic printing machines of the automatic printing plate processing apparatus. The baked printing plate is conveyed by the printing plate branching means to a first printing plate correspondence conveying means corresponding to the type of printing plate, and is conveyed to a plurality of developing steps respectively corresponding to the plurality of printing plate types. For this reason, it is possible to reduce the number of operations for transporting the discharged printing plate to a developing process or the like by an operator or the like.

Further, according to the present invention, the printing plate, which has been subjected to the development processing in a plurality of development steps respectively corresponding to the plurality of printing plate types, is subjected to the pattern area ratio measurement step by the printing plate-compatible second transport means. Transported to For this reason, it is possible to reduce the work of transporting the developed printing plate to the picture area ratio measuring step by an operator or the like. In this case, the pattern area ratio measuring step may be installed in each of the plurality of developing steps. However, if the printing plate-compatible second conveying means is joined to be conveyed to one pattern area ratio measuring step, the pattern area ratio measuring step may be performed. It is possible to reduce the equipment for the area ratio measurement process.

Furthermore, according to the present invention, the fully automatic printing machine that has performed printing is specified based on the information from the printing plate identification control means, and the identifier providing means provides an identifier to the printing plate. Based on the data, a necessary printing plate management number, a printing machine on which the printing plate is to be set, data such as the number of ink keys, and the like are selected to measure the pattern area ratio. Since the identifier providing means is based on the information from the printing plate identification control means, at least one of the first carrying means, the second carrying means, the rotating device, the first carrying means for printing plates, and the second carrying means for printing plates. , It is not necessary to install it for each fully automatic printing machine, the equipment can be reduced, furthermore, the second transport means after the development is completed, the second transport means corresponding to the printing plate, When installed on any of the rotating means that is installed after the development is completed, it is possible to reduce the necessity of giving the identifier itself a resistance that can withstand the development process, and it is possible to widen the range of selection of the identifier.

Further, according to the present invention, the position of the printing plate being transported is identified by the transport printing plate identification means provided in the first transporting means or the printing plate corresponding first transporting means.
Further, based on the information from the transport printing plate identifying means, the fully automatic printing machine control means, when discharging the printing plate from the fully automatic printing machine to the first transport means or the printing plate corresponding first transport means, It is determined whether or not the printing plate overlaps with another printing plate. If the printing plate overlaps, the discharging from the fully automatic printing machine is temporarily stopped, and the discharging is resumed when the printing plate no longer overlaps. The transport printing plate identification means is provided substantially continuously with the first transport means or the first transport means corresponding to the printing plate, and grasps the position of the printing plate and its movement in real time, and discharges from any fully automatic printing machine. Whether the printing has been performed is determined based on whether or not a new printing plate has appeared by the transport printing plate identification unit. Of course, the printing plate discharge information may be obtained from the fully automatic printing machine itself or the fully automatic printing machine control means. As described above, the position and movement of the printing plate on the transporting device discharged from each fully automatic printing plate machine by the transporting printing plate identification unit are grasped in real time, and the printing plate discharge control unit and / or based on the information. The printing plate identification control unit and / or the printing plate branching control unit are controlled and / or identified to discharge a specific type of printing plate, assign an identifier, and branch a specific type of printing plate.

Further, according to the present invention, the first transporting means or the first transporting means corresponding to the printing plate is constituted by a plurality of transporting parts, and the transporting printing plate identifying means determines the printing plate on each transporting part. Identify presence or absence. This transport printing plate identification means is provided between the position on the transport portion of the printing plate and the transport portion from the time when the printing plate is discharged from each fully automatic printing machine and mounted on the transport portion to the time when the printing plate is inserted into the developing process. Since the position movement is identified, it is possible to determine in real time from which identification plate the printing plate discharged from which fully automatic printing machine is located on which transport site. In addition, when the printing plate is discharged based on the information from the fully automatic plate printing machine by carrying and stopping each transfer part independently, other printing is performed on the transfer part where the discharged printing plate is mounted. The transport site in front of the plate is temporarily stopped so that there is no plate. In that case, there is no need to stop the discharge of the printing plate from the fully automatic intaglio machine, and it is possible to keep the efficiency of the fully automatic intaglio machine without decreasing.

Further, according to the present invention, the information on the type of printing plate is specified based on the exposure time which fluctuates greatly depending on the type of the printing plate, and this exposure time information is obtained from a fully automatic printing machine or the like. The discharge or branch is controlled by the printing plate discharge control unit or the printing plate branch control unit based on the information to discharge or branch the printing plate. Since the type of the printing plate is specified based on the exposure time, it is possible to omit the operation of the operator to specially input the type of the printing plate. Of course, the invention of the present application is based on the fact that, when the operator inputs the type of printing plate on the fully automatic printing machine side, when specifying the exposure time, on the contrary, the information of the type of printing plate input in place of the exposure time is used. Alternatively, both the exposure time and the information of the type of the printing plate may be input. Note that the exposure time may be an actual time such as seconds or a count value of an integrating light meter.

Further, according to the present invention, calibration data for each type of printing plate at the time of measuring the pattern area ratio is stored in the storage device, and when the type of printing plate is specified, this calibration is performed. By extracting data from the storage device and measuring the pattern area ratio based on the data, it is possible to reduce the work of printing a calibration mark for each printing plate.

The stop sensor 53 detects one side of the printed printing plates 5 and 8 and stops driving the transport roller 56. The printed printing plates 5 and 8 have their one side abutting against the positioning plate 51, and the conveyance thereof is stopped.

The printing plate detection sensor 54 has a function of detecting one corner of the printed printing plates 5 and 8 and driving an identifier providing means 58 such as a bar code printing device or a label attaching device. The identifier providing means 58 is a printing plate detection sensor 5
When 4 is turned on, it plays a role of directly printing an identification mark such as a barcode on a predetermined position of the printed printing plates 5 and 8 or attaching a label printed with the identification mark such as a barcode. The control of the identifier providing means 58 is performed by the printing plate automatic processing control device 110. The identification mark is provided in advance by the fully automatic reproduction machine controller 111A (or 1

[0048] Fully automatic breeding machine 112A (or 112B)
When the positional relationship of the pattern with respect to the printed printing plate is not compatible with the pattern area ratio measurement process, the positional relationship of the printed printing plate transported from the fully automatic printing machine 112A (or 112B) is determined by the pattern area. It is rotated so as to be suitable in relation to the rate measuring step and transported toward the developing step. That is, the printed printing plate 8 shown in FIG. 11A is rotated by 90 degrees, changed to the posture shown in FIG. 11B, and transported toward the picture area ratio measuring step.

However, if the printing plate detection sensor 57 is provided on the rotary table 49 every 90 degrees, the rotary table can be rotated. It is not necessary to reversely rotate the table 49.

Next, the case where the rotating device 46 is used as a part of the printing plate discharging means will be described. The printing plate detection sensor 57 is turned on when the leading edge of the printing plate traverses, is turned off when the baked printing plate passes the printing plate detection sensor 57, and the printing plate detection sensor 57 turns the baked printing plates 5 and 8 on the rotary table 49. It plays the role of detecting whether or not it has been placed on the device. The transport rollers 50 and 55 are a printing plate detection sensor 57.
Is driven simultaneously with turning on, and is stopped simultaneously with turning off. The transport roller 56 is driven at the same time as the printing plate detection sensor 57 is turned off. The printed printing plate is driven by the transport roller 56 in the direction opposite to the above-described rotation, that is, in the direction opposite to the positioning plate 51. The second stop sensor 45 detects one side of the printed printing plate, and stops driving the transport roller 56 when the printed printing plate passes the second stop sensor 45. The printed printing plate discharged from the rotating device 46 is delivered to a discharge stocker 114, where it is stocked. The control when the rotating device 46 is used as a part of the printing plate discharging means is performed by the printing plate automatic processing control device 110.

0 and 70 are driven, and the posture of the printed printing plate is aligned parallel to the transport direction. This positioning is performed when the picture area ratio is measured, but it can also be performed with respect to an identification mark reading device (not shown).

The picture area ratio measuring means 62 has a frame 73 as shown in FIG. 7 between left and right sides of frame 73
Feed rollers 75, 75 for transporting the printing plate into the frame 73 are provided on the reference numerals 4, 74 via bearings 76, 76. Each of the feed rollers 75 is driven to rotate by a servomotor 77 installed on a frame 73 via a timing belt 77 '. The movable frame 7 is provided on the side surfaces 74, 74.

A bracket 84 is stretched over the side surfaces 74, 74. A guide rail 85 is provided on the bracket 84. The measuring head 83 is driven via a guide roller 86 as shown in FIG. The measuring head 83 is driven by the timing belt 87. The timing belt 87 is stretched around a timing pulley 88 and a timing pulley 89, and the timing pulley 88 is driven by a servomotor 90. The timing belt 8

Four contact rails 91 are stretched over the side surfaces 74, 74 of the frame 73, and the contact rails 91 extend parallel to the bracket 84. One contact rail 91 is supported on each surface of a support member 91 ′ having a square cross section. The contact rail 91 is in electrical contact with four contact brushes 92 provided at the rear of the measuring head 83. The contact rail 91 and the contact brush 92 constitute power supply and communication means.

The bracket 84 is provided with a scale member 93. At the rear of the measuring head 83, a photo interrupter 94 is provided so as to sandwich the scale member 93 from above and below. At the front of the measuring head 83, a box body 95 containing a light source (not shown) and a photoelectric converter is provided. The box body 95 is moved up and down by the movable frame 96 to be separated from and approached to the printing plates 5 and 8 having been printed.

The measurement data based on the slit detection pulse from the photo-interrupter 94 and the amount of reflected light from the photoelectric converter is input to the measurement head control unit 97, which processes the measurement data and processes each ink key. The pattern area ratio for each image is calculated, and the data is filed (see Japanese Patent Application No. 2-246142). Prior to the picture area ratio, the condition data of the identification mark is read by the identification mark reading device, and the measurement is executed based on the identification mark.

The printing plate whose pattern area ratio has been measured is transferred to a washing machine 99 for washing the printing plate by a conveyor belt 98, and after washing with water, the surface is leveled by spraying a chemical on the surface. Transferred to 100. Then, the printing plate is transferred to the next-stage burning machine 101, where the photosensitive agent is cured to improve the printing durability of the printing plate. Then, the toner is transferred to the gumming device 103 by the conveyor belt 102, and rubberized. Next, the printing plate is transferred to the dryer 104, and the printing plate is stocked in the stocker 105.

FIG. 8 is a block diagram showing the data flow of the first embodiment. In the figure, reference numerals 121, 122, and 123 denote input means, and a fully automatic printing machine control means 124 and a transport control means 12 are provided inside the printing plate automatic processing control device 110.
5, printing plate identification control means 126, printing plate discharge control means 1
27, there is a rotation device control means 128. As described above, in the first embodiment, the printing plate discharging means and the rotating means are also used, but they may be separated.

The input means 121, 122 and 123 are composed of a monitor and a display for displaying input information and a keyboard and the like for input operation. Of course, it is not necessary to limit to this. If there is a system or the like for managing the printing progress in the factory and information necessary for printing etc. can be obtained from this printing progress management system, connection with the printing progress management system When the printing progress management system performs progress management and data management using an identifier such as a barcode, an identifier reading device is further added.
The input means 121, 122, and 123 have the same data input function in principle, and input data include a job number used in the above-described fully automatic printing machine, a printing plate size, and a register mark for each printing color. Designation of each color, printing position of positive or negative film, printing order, number of printings, exposure time at the time of printing (or counting number of integrated light meter), printing plate control number and other printing plates are set. There are condition data and the like (hereinafter, referred to as basic printing data) required for measuring the pattern area ratio such as the number of printing presses and ink keys to be used. Of course, it goes without saying that the type of printing plate may be input simultaneously as described above.

When the basic printing data is input to the input means 121, the basic printing data is temporarily stored in the automatic printing machine control means 1 in the printing plate automatic processing control device 110.
24, and the basic printing data is sent to the fully automatic printing machine controllers 111A and 111B. At that time, the input means 121 specifies a fully automatic printing machine to which data is to be sent. When the basic printing data is input to the input means 122 and 123, the basic printing data is temporarily stored in the fully automatic printing machine controllers 111A and 111.
B, and the printing basic data is sent to the fully automatic printing machine control means 124. At that time, the fully automatic intaglio machine can be specified by the fully automatic intaglio machine controller, and there is no need to specify the fully automatic intaglio machine that uses the basic printing data. Fully automatic breeding machine controller 111A, 11
1B is a fully automatic printing machine 1 based on the basic printing data.
12A and 112B are controlled to perform a printing operation.

The full-automatic printing plate control means 124 does not directly control the full-automatic printing plate machine, but stores and accumulates basic printing data.
Send to 111B. This is because, when a trouble occurs in the fully automatic printing machine, the basic printing data of the scheduled printing operation is sent to another fully automatic printing machine, and the business is quickly performed. Also, a printing plate identification control unit 12 described later.
When the instruction to stop the discharge is sent from 6, the instruction to stop and restart the discharge of the printing plate is sent to the fully automatic printing plate controllers 111A and 111B.

The transport control unit 125 uses the identification information from the transport printing plate identifying units 118A to 118D to identify the transport site 113.
The position of the printing plate placed on each of the transport portions 113A to D is determined based on this position information and the printing plate discharge information from the fully automatic plate printing machine control means 124. Is to be driven or stopped, and the transport driving means of each part is driven and stopped. For example, in the case of FIG.
The transport control unit 125 receives the passing information of the printing plate 5B from the transport printing plate identifying unit 118C and does not receive the passing information of the printing plate 5B from the transport printing plate identifying unit 118B. And instructs the transport driving means of the transport portion 113B to drive. Next, the transport printing plate identification unit 118B
Before the printing plate 5B is identified, when the ejection information of the printing plate 5A is sent from the fully automatic printing plate controller 111A through the fully automatic printing plate control means 124, the transporting portion 113
The transport driving means B is instructed to stop, the printing plate 5B is made to stand by on the transporting part 113B, and at the same time, the driving is instructed to the transporting driving means of the transporting part 113A. Transport site 113A
The printing plate 5A discharged above starts to be conveyed and starts to pass over the conveyed printing plate identification means 118A.
8A sends the identification information to the transport control means 125, and this identification information is sent continuously until the passage of the printing plate 5A ends. The transport control unit 125 includes a transport printing plate identification unit 118
When the identification information from A stops, the printing plate 5A recognizes that the printing plate 5A has been transported to the next rotating device from above the transport portion 113A,
The transport driving means of the transport portion 113B is instructed to drive, and when the transport printing plate identification means 118B identifies passage of the printing plate 5B, the transport driving means of the transport portion 113A is instructed to drive, and the transport printing plate identification means 118B is provided. Stops the identification information of the printing plate 5B, the printing plate 5B
Identify that it has moved onto A.

In the first embodiment, the control is carried out so that only one printing plate is always present on the transport portion. However, this is because only two fully automatic printing machines are connected. This is because there is spare capacity in the transport means, and there is no need to limit to this. That is, if the printing plates do not overlap each other on the first transport means, it is possible to identify which fully automatic printing machine the printing plates are baked on and at which position on the first transport means, May be controlled so that a plurality of printing plates straddle the transfer portion. That is, in FIG. 3, the printing plate 5B is ejected, the transport printing plate identification means 118A starts to identify the passage of the printing plate 5A, and when the printing plates 5A and 5B have a sufficient distance, the transport driving of the transport portion 113B is started. A means may be instructed to drive, and a part of each of the printing plates 5A and 5B may be placed on the transport portion 113A with a distance.

To give an example of such a case, the fully automatic intaglio machine controller 111A to the fully automatic intaglio machine control means 124
The transfer control unit 125 receives the discharge end information (using the suction stop signal of the suction mechanism 39) of the printing plate 5A through
After that, set for a certain period of time (the time taken for the printing plate to fall from the suction mechanism to the transporting site and the time for the printing plates to take a certain distance. Is obtained.) After the lapse of time, the transport printing plate identification unit 118A causes the printing plate 5
Even if the end of the passage of A is not identified, the drive may be instructed to the transport driving unit of the transport portion 113B.

The printing plate identification control unit 126 receives the printing plate position information from the transfer units 113A to 113D from the transfer control unit 125 and the printing basic data from the fully automatic printing plate control unit 124, and associates them. And constantly identifying which printing plates are currently where. In this case, based on the printing basic data from the full-automatic printing plate control means 124, the information such as the job No., the printing order, and the designation of each color is used. One sheet can be identified, and even if a plurality of printing plates printed by the same fully automatic printing machine are present on the first transport means, they will not be confused based on information such as the printing order and color designation. Upon receiving the printing plate mounting information (using the signal of the printing plate detection sensor 57) from the rotating device 46, the printing plate identification control means 126 fully automatically outputs the data necessary for identification in the corresponding printing basic data. Read from the plate control means 124,
The printing plate is identified.

For the identification, the type of the printing plate is determined from the exposure time at the time of printing (or the count number of the integrated luminometer). When directly inputting the type of the printing plate, the information is used.
This is because some manufacturers have the same exposure time for both positive and negative exposures. It is determined whether or not this printing plate is to be discharged, and if so, the printing plate discharge control means 1
27, and if not, determine whether or not there is rotation by the printing machine to be set. If it is to be rotated, it is instructed to rotate to the rotating device control means 128. An instruction is given to the rotation device control means 128 to convey the printing plate.

The printing plate detection sensor 54 detects the printing plate,
When the identifier assigning unit 58 assigns an identifier to the printing plate, the identifier assigning unit 58 sends the identifier information to the printing plate identification control unit 126, and the printing plate identification control unit 126 transmits the identifier information and the pattern in the printing basic data. The data necessary for the area ratio measurement is associated with each other, and the association information is sent to the pattern area ratio measuring means 62. The pattern area ratio measuring means 62 calls the stored printing basic data based on the identifier information read by the identification mark reading device,
The pattern area ratio is measured. Although the identifier is used in the first embodiment, the identifier can be omitted. That is, since the printing plate enters the picture area ratio measuring means 62 in the order of passing through the rotating device, the printing basic data may be used in the order sent from the printing plate identification control means 126. However, if another baking process such as a hand baking process exists in the same workplace, it is wasteful to provide a developing process and a pattern area ratio process separately. We decided to use identifiers so that they could be inserted freely. In this case, there is a separate means for inputting data necessary for the picture area ratio measurement to the identifier providing means and the picture area ratio measurement means 62.

The association information sent by the printing plate identification control means 126 to the picture area ratio measuring means 62 includes data of the printing plate type, and the pattern area ratio measuring means 62 uses the data of the printing plate type based on the data of the printing plate type. Then, from the calibration information section which separately stores the type of the printing plate and the reflected light amount information of the printing plate printing portion, the reflected light amount information corresponding to the printing plate is called and used as calibration data. In this case, the printing of the calibration marks 9 in FIGS. 10 and 11 can be omitted, and the efficiency of the fully automatic printing machine can be improved by reducing the number of printings per printing plate by one (see FIG. 10). Most of the operation time of the fully automatic printing machine is occupied by vacuum and exposure time, and the number of printings greatly affects efficiency). Needless to say, in the present invention, a burned calibration mark may be used.

As described above, in the first embodiment, the case where the number of the fully automatic printing machines is two has been described. However, the present invention is not limited to this. Can be similarly performed.

FIG. 13 is a second embodiment of the present invention, and is an enlarged view of another first conveying means. In the first embodiment,
The first transport unit is divided into transport sections, and the printing plate identification control unit is provided for each transport section. However, the present invention is not limited to this, and the first transport unit is integrated as in the second embodiment. May be configured. In FIG. 13, 13
Numeral 0 denotes a drive roller, 131 denotes an auxiliary roller, 132 denotes an endless belt, 133A to L ... denote transport printing plate identification means, and the same numbers are the same as in the first embodiment. The drive roller 130 is driven by conveyance driving means (not shown).
42, 142. The endless belt 132 is stretched over the driving roller 130 and a roller at the other end (not shown), and is supported flat by the auxiliary roller 131. Although the block diagram showing the data flow of the second embodiment is the same as that of FIG. 8, the transport parts 113A to 113D and each transport drive unit become one, and the transport printing plate identification units 118A to 118A.
D becomes 133A-L ....

The transport printing plate discriminating means 133A-L... Are arranged at regular intervals along the center of the first transporting means.
In this case, the identification information of the printing plate is sent to the transport control unit 125 in the printing plate automatic processing control device 110. The transport control unit 125 includes transport printing plate identification units 133D and 13D.
3G does not detect the printing plate, and the transported printing plate identification unit 133
E and 133F detect the printing plate 5B,
It recognizes that there is a printing plate 5B between D and 133G, and recognizes that there is no printing plate between 133A and 133D by the transport printing plate identification means 133A, 133B and 133C not detecting the printing plate. When the discharge information of the printing plate 5A is sent from the fully automatic printing machine control means 124, the conveyance control means 1
25 confirms the presence or absence of a printing plate at the lowered position of the printing plate 5A, and if there is a printing plate, instructs the fully automatic printing machine control means 124 to stop discharging, and the suction mechanism 39A keeps the printing plate 5A suctioned In the standby state, when there is no printing plate, the suction mechanism 39A stops the suction of the printing plate 5A, and the printing plate 5A is lowered and placed on the endless belt 132.

In FIG. 3, when the printing plate 5B and the printing plate 5A overlap, the suction mechanism 39A is in a standby state while sucking the printing plate 5A, and is in a standby state until the printing plate 5B passes the lowering position of the printing plate 5A. When the continuation and conveyance control means 125 recognizes the passage of the printing plate 5B, it instructs the fully automatic printing plate control means 124 to discharge, the suction mechanism 39A stops suction, and the printing plate 5A descends on the endless belt 132. Is placed. During this time, the transport control unit 125 sends the position information of the printing plate to the printing plate identification control unit 126, and the printing plate identification control unit 126 recognizes the position of each printing plate and prints the printing plate as in the first embodiment. The discharging means, the rotating means, and the identifier providing means are controlled.

In the case of the second embodiment, the structure of the first conveying means 113 can be simplified as compared with the first embodiment, but since the printing plates do not overlap, the suction mechanisms 39A, 39A are used.
Since B is in the standby state, the next printing plate is fully automated
It cannot be supplied to 12A, 112B, and the efficiency of the fully automatic printing machine 112A, 112B will be reduced.
In addition, when the suction mechanism is equipped with two suction plates exclusively for printing plate supply and printing plate discharge, the efficiency of the fully automatic plate printing machines 112A and 112B can be reduced even in the second embodiment. Although there is no lowering, there is an effect of simplifying the structure of the first transport means 113, but there is a disadvantage that the suction mechanism is complicated. Needless to say, any of them can be selected in the present invention.

As described above, in the second embodiment, as in the first embodiment, the case in which the number of the fully automatic breeding machines is two has been described. However, the present invention is not limited to this. The same can be applied to a case where there are two or more plate machines.
