[Industrial application fields]
In the production machine which obtains a roll-shaped product by printing or other processing on a web such as paper or plastic film, the present invention is defective in order to convey printing processing defect information (contents and position) to each subsequent roll. The present invention relates to a method and apparatus for efficiently collecting information. In particular, the present invention relates to a method and apparatus for collecting defect information by online connection of a process management terminal and an inspection apparatus of each production machine.
[0002]
[Prior art]
For example, as described in JP-A-5-181870, a process management terminal (terminal device) is a component of a production machine and collects data from equipment for operating the production machine, and further data manually input by an operator To generate process data such as the operating status of production machines, quantity of products, and quality. For example, in a printing press, the line shaft rotation signal that conveys the driving force to multiple printing units and the operation panel signal are captured as data, and the operator is adjusting the printing conditions, or the adjustment is completed and If the user is manually entering the printing stage, the quantity of regular paper can be obtained by the process management terminal.
On the other hand, the inspection device is a device for inspecting the quality of the product obtained by the production machine and obtaining inspection data, and it can be provided in a part immediately before the web is wound up in the production machine and inspected inline. For example, it can also be provided in a post-process machine different from a production machine such as an inspection defect removing device.
[0003]
Conventionally, for example, when an inspection device is used in-line on a web printing machine, the operator switches on the inspection device to start the inspection when printing on regular paper, and at the end of printing, turns off the inspection device and ends the inspection. . Also, if the inspection device detects a defect during normal paper printing, an alarm is sent to the operator, and the operator checks whether there is any abnormality in the operation status of the printing machine, and if necessary, operates the printing press. Work to remove the cause of the failure by interrupting. Moreover, the defective part of a product is also removed although it is not necessarily.
However, some of the defects continue like a doctor streak due to doctor spillage in gravure printing, but it happens to be temporary and not continuous as when machine oil or dust adheres to the printed matter. There is a defect. Such a transient failure has no direct cause of failure in the printing machine, and therefore does not interrupt the operation of the printing press or remove the defective part of the product on the printing press.
[0004]
[Problems to be solved by the invention]
As described above, when a web is supplied with a roll in web printing and the web printed with the roll is collected, the defective part of the product is removed without interrupting the printing machine even if a defect occurs. Also not done. Therefore, the rolls printed by the printing machine and the data of the results inspected by the inspection device are managed as one set.
If the production machine is equipped with a process management terminal, the process management terminal collects the process data about each roll collected from the manual input of the production machine and the operator, and the inspection data about each roll obtained by the inspection device. Collected by.
Conventionally, however, process data and inspection data are collected separately without being associated with each other. Therefore, the operator of the production machine associates and edits raw data of many pieces of defect information output from the inspection device with process data. I had to start over.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a defect information collection method and apparatus for obtaining data associated by editing process data and inspection data in a process management terminal without bothering an operator.

[0007]
【Example】
The defect information collecting method and apparatus of the present invention will be described below based on preferred embodiments.
FIG. 1 is a diagram for explaining the configuration of a defect information collecting apparatus according to the present invention. In FIG. 1, 1 is an unprocessed roll of paper, plastic film or the like on the paper feed side of the production machine, 2 is a web supplied from the roll and processed by the production machine, and 3 is a process wound on the paper discharge side. It is a finished role. Reference numeral 4 denotes a process management terminal composed of a computer main body and display, keyboard, mouse, storage device, LAN (Local Area Network) connection device, and the like. Reference numeral 5 denotes an instruction PB (an operator input data to the process management terminal). (Push Button Switch), 6 is a machine signal output from the production machine to the process management terminal.
Reference numeral 7 is an inspection apparatus body, 8 is an imaging camera that converts visual images into electrical signals, 9 is a communication means for communicating data between the process management terminal 4 and the inspection apparatus body, and 10 is a communication means. The operation instruction is output from the process management terminal 4 to the inspection apparatus body 7 through 11, and 11 is inspection data output from the inspection apparatus body 7 to the process management terminal 4 through communication means.
[0008]
The operation in the above configuration will be described. The web 2 is sent from the unprocessed roll 1 in the paper feed section of the production machine, and the web 2 reaches the paper discharge section while being processed in the processing section, and is wound there to obtain the processed roll 3. In the process, a machine signal 6 indicating the operation state of the production machine is output from the control device of the production machine, the operation panel, etc., and is input to the process management terminal 4.
For example, in the case of a printing press, the machine signal indicating the operation state includes a rotation signal of a line shaft to which a prime mover is connected, a removal signal of an impression cylinder, a tension signal of a web, and the like. The line shaft rotation signal can be used to detect the stop, preparation, and operation of the printing machine. If the impression cylinder is the arrival signal and the web tension signal is normal in the operation state, printing can be performed on the printing paper. It can be seen that it is being performed. In this way, various states of the production machine can be known from the machine signal 4.
[0009]
Further, the instruction PB5 can be input manually by the operator into the operation status of the production machine in the process management terminal 4. For example, in the case of a printing machine, when the adjustment of color tone registration, registration, etc. is completed and the quality of the printed material reaches a predetermined level, it is manually entered that regular paper printing has started. By this input, the production quantity of the regular paper can be correctly counted by the process management terminal 4.
An operation instruction 10 is given from the process management terminal 4 to the inspection apparatus body 7 through the communication means 9. The contents of the operation instruction 10 include inspection start, inspection end, inspection condition setting (inspection range, inspection item, inspection standard, inspection result output method), operation check, and the like. In addition, inspection data 11 is output from the inspection apparatus body 7 to the process management terminal 4 through the communication means 9. The contents of the inspection data include dust, foreign matter, ink splashes, doctor streaks, discoloration, poor color tone, registration failure, etc., and correspond to the inspection items of the inspection apparatus. In the embodiment, a camera is used as the sensor. However, in the present invention, the inspection apparatus is not limited to the appearance inspection apparatus, and includes inspection apparatus for inspection items relating to all specifications of the product.
[0010]
In the process management terminal 4, the inspection data can be taken and recorded or stored as it is. However, in the present invention, the inspection data is edited and added to the process data.
The process data is an operation history of the production machine, and is data in which the web position and the web state are recorded in the processed roll 3 from the winding core, that is, in order from the start of the process. The core portion may include a web in the production state adjustment period, and the web that can be used as a product is the web from where the operator has manually input from the instruction PB5 that the paper is normal. In addition, the processed roll 3 may include web splicing, and may include a portion in which the registration control device has informed of the occurrence of a registration failure during production. There may be a part that informs you.
Therefore, the processed roll 3 needs to be accompanied by data in which the web position and the web state are recorded for the subsequent process. In the present invention, the inspection data is edited and written in the process data. Added.
[0011]
Next, the defect information collecting method and apparatus of the present invention will be described in further detail. FIG. 2 is a flowchart showing a series of flow of defect information collection according to the present invention. FIG. 3 is a flowchart subsequent to FIG.
In FIG. 2, first, the operator determines whether or not preparation adjustment has been completed in the production machine and regular paper production has started (S1). When normal paper production is started, the operator inputs a normal paper production start to the process management terminal 4 from the instruction PB (S2). The process management terminal 4 starts collecting process data through the machine signal 6 (S3). In the process management terminal 4, an operation instruction 10 for starting the inspection apparatus operation is sent to the inspection apparatus body 7 through the communication means 9 (S4). Upon receiving an instruction to start the inspection apparatus operation, the inspection apparatus starts operation (S5).
[0012]
When the inspection apparatus starts operation, inspection data 11 is transferred from the inspection apparatus body 7 to the process management terminal 4 through the communication means 9. When a defect occurs, the inspection data 11 includes defect information. Even when no defect occurs, the inspection data 11 includes data relating to the quality grade of the product (S6). The inspection data 11 is taken in by the process management terminal 4 and recorded on a recording medium or stored in a storage device (S7). The process management terminal 4 collects various data and determines the presence / absence of defect information from other than the inspection apparatus based on the process data from the machine signal 6 (S8). If there is defect information from other than the inspection apparatus, the failure information is preferentially taken in and input of the inspection data 11 is blocked (S9).
[0013]
As defect information from other than the inspection device, the web is automatically continued without stopping the operation of the production machine, for example, when the web of the unprocessed roll runs out and the roll is replaced with a new unprocessed roll. Quality defects occur before and after the web is spliced and the seam passes through the production machine. Therefore, in the process management terminal 4, when the machine signal 6 that connects the web is input, it is determined that a defect occurs for a certain period from the web path of the production machine using the signal as defect information.
[0014]
Next, in FIG. 3, when there is no defect information from other than the inspection apparatus, it is determined by the operator whether or not the production is finished, and when the production is not finished, the process returns to S6 in FIG. 2 (S10). In the case of the end of production, the operator inputs the end of production of regular paper from the instruction PB (S11). In the process management terminal 4, the collection of the inspection data is finished (S12), and when the operation instruction 10 for finishing the operation of the inspection apparatus is output to the inspection apparatus through the communication means 9, the inspection apparatus ends the operation. (S13).
[0015]
Further, the failure information is assigned by the operator in the process management terminal 4, and when the assignment is made, the inspection data for that portion is deleted (S14).
In the assignment of defect information by the operator, defect information that has not been input only from the machine signal 6 is input by the operator in the record, work memo, storage, etc. of the process management terminal 4. For example, when a defect is generated by operating a device from which the machine signal 6 has not been extracted, if there is a defect that cannot be detected by the inspection apparatus but is found by a quality check by the operator, it is inherited to the raw roll 1 and coated. This is the case where there is a defect such as a defect and there is recorded data but the defect is not detected in this process.
Finally, the operator inputs an end to the process management terminal 4 from the instruction PB (S15), and the process management terminal ends the operation (S16).
[0016]
FIG. 4 is a flowchart of the inspection data input blocking process (S9 in FIG. 2) in the defect information collecting method and apparatus of the present invention. In FIG. 4, first, defect information other than the inspection apparatus is captured by the process management terminal 4 (S21). The process management terminal 4 prevents the inspection data 11 output from the inspection apparatus body 7 from being output to the process management terminal 4 through the communication means 9 (S22). Defect information other than the inspection apparatus is added to the process data by the process management terminal 4 (S23).
[0017]
FIG. 5 is a flowchart of the defect information assignment process (S13 in FIG. 3) in the defect information collection method and apparatus of the present invention. In FIG. 5, the operator sets the process management terminal 4 to the defect information manual input mode and inputs the defect information from the keyboard or the like (S31). Then, the process management terminal 4 assigns defect information to process data based on the defect information input by the operator. As a result of the assignment, the content that what kind of content defect exists in which part of the processed roll is recorded (S32).
For example, in the case of printing, the content is that the portion in the third row from the left between 120 to 160 meters from the core of the processed roll is defective due to dirt.
Thereafter, the record of the inspection data within the range to which the defect information is assigned by the process management terminal 4 is deleted (S33).
[0018]
Next, how to use the defect information collecting method and apparatus of the present invention will be described by taking a processing system for soft packaging materials as an example.
FIG. 6 is a diagram showing a system configuration example incorporating the defect information collecting method and apparatus of the present invention. In FIG. 6, 12 is a server computer, 13 is connected to the server computer 12 through a communication line, and is a logistics computer for controlling equipment for transporting and storing the raw roll 1, processed roll 3, etc., and 14a to 14c are processing devices. They are a printing machine, a coating machine, and a slitter, respectively. 7a and 7b are inspection apparatuses provided in the printing machine 14a and the coating machine 14b, 15 is a defect removing apparatus, 16 is a conveying means for winding material, 17 is a receiving means for winding material, and 4a to 4d. Is a process management terminal connected to the server computer 12 through a communication line, and a display is connected to each of them. The operator of the processing apparatus advances the work while confirming information such as a processing schedule displayed on each display. be able to.
[0019]
The operation of the above configuration will be described. The server computer 12 stores data of machining schedules and work schedules of each machining apparatus and defect removal apparatus. The data includes items, schedule of work, operating conditions of the machine, scheduled quantity of regular paper, winding materials with rolls of paper and plastic web, auxiliary materials such as printing plates, inks, coating liquids, etc. Information is included.
Such processing schedule and work schedule data are sent from the server computer 12 to each process management terminal 4a to 4d, and necessary information therein is displayed on each display. Each operator recognizes a work to be performed next while looking at the display, and executes a scheduled work.
In addition, information such as the quantity and quality of the product produced by the production machine is output from the process management terminal 4 to the server computer 12, and when the raw material is received or when the product is transferred from each processing device to the storage means and received. The distribution information such as the distribution information is output to the server computer 12 by the distribution computer 13. Therefore, the server computer 12 stores data relating to the stock status of the winding material and auxiliary material, and the corresponding data is also stored in the physical distribution computer 13.
[0020]
Here, a case where the operator starts production work of a new item will be described. First, when an operator gives an instruction (item switching instruction) to the server computer 12 by manual input from the process terminal device or the operation panel of the production machine, an instruction is issued from the server computer 12 to the distribution computer 13, and the distribution computer 13 is unmanned. The transporter controls the new winding material and auxiliary material to a predetermined location near the production machine, and the previous winding material (remaining unprocessed roll, processed roll) and auxiliary material (printing plate) , Residual ink and residual coating liquid) are collected and transported and stored in a predetermined storage location.
At this time, process data for each processed roll regarding the previous processed roll is transferred from the process terminal device to the server computer 12 and stored therein. As described above, this process data includes inspection data output from the inspection apparatus in an edited form.
Next, the operator sets a new winding material and auxiliary material on the production machine and adjusts the production conditions so that a good product is produced.
When the normal paper is produced, the operator inputs the start of production of the normal paper to the process terminal device 4 by manually inputting from the instruction PB5.
[0021]
Next, a case where defect removal work is performed in the system configuration of FIG. 6 will be described. When removing defects in a roll-shaped product, there are cases where defects are removed from a wide processed roll before slitting, and defects are removed from a narrow processed roll after slitting. . Usually, the former method is used when the defect extends over the entire width of the web, such as poor color tone, and the latter method is performed when the defect is only in a part of the web flow direction, such as a doctor line.
The defect removal device is a fully automatic device that removes the defective portion and connects the correct paper portion, and a device that removes the defective portion and connects the correct paper portion by performing a visual inspection while referring to the inspection data of the previous process ( Rewinding device). In FIG. 6, the defect information regarding the processed roll is transferred from the server computer 12 to the process management terminal 4d of the defect removing apparatus 15, and the defect is removed using the defect information.
[0022]
First, the operator sets the processed roll to be inspected in the paper feed unit of the defect removal apparatus. In addition, the operator inputs the processed roll item, roll number, and the like at the process management terminal 4d, and sets the defect information in the defect removal apparatus 15.
Next, when the operator starts the defect removing device 15, the defect removing device 15 unwinds the processed roll and winds it on the paper discharge unit. Then, the web transfer is decelerated immediately before the defective web in the defect information is unwound. The operator visually inspects the web, and inputs an input for stopping the web transfer to the defect removing device 15 when the defective portion reaches immediately before the splicer portion.
In the splicer unit, the end of the downstream web is pressed, and the upstream web is wound around the defective paper discharge unit. When the operator inputs defect feed to the defect removal device 15, the defect removal device 15 recognizes the end portion of the web defect from the defect information, and the web is transferred when the defect end portion is wound around the defect discharge portion. To stop.
A bad web is cut off at the splicer section, and the upstream and downstream web ends are connected. Then, the processed roll is unwound and wound around the paper discharge unit until the next defective portion is reached.
By repeating the above, defects are removed.
