[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a data collection method and a data collection device from a molding machine, and in particular, to a molding machine having only a printer port dedicated to output for outputting data of a predetermined content to a printer, and to a data collection device. Even if a data input / output port is provided in addition to the printer port, data from the molding machine whose data input / output format is unknown is collected and processed. The present invention relates to a data collection method and a data collection device suitable for a computer.
[0002]
[Prior art]
Usually, a molding machine, for example, an injection molding machine is provided with at least a printer port. As will be described in detail later, the printer port is an output-only terminal for printing out actual data during molding, for example, data such as weighing time and injection pressure by a printer. Injection molding machines may also be provided with I / O ports in addition to printer ports. The I / O port is an input / output terminal for outputting an operation signal, an abnormal signal, and the like of the injection molding machine, and for inputting an operation command signal, a stop command signal, and the like, as will be described later. is there.
[0003]
In addition to such ports, recently, ports called serial ports and LAN ports have been provided to enable data communication with a management device realized by a personal computer or the like. The type of data output from both the serial port and the LAN port is almost the same as the data from the printer port, but differs from the printer port in that bidirectional communication is possible.
[0004]
In any case, the data output from each port is performed under the control of a control device provided in the injection molding machine. The control device receives signals from various sensors installed in various parts of the injection molding machine, and is connected to various peripheral devices described later to control a molding operation. On the other hand, the management device is provided for the purpose of managing not only one injection molding machine but also a plurality of injection molding machines.
[0005]
By the way, the printer port and the I / O port are almost common even when the injection molding machine manufacturer is different. This is to provide versatility so that any type of printer connected to the printer port can be used as long as it satisfies certain conditions. Also, the type of the I / O port is limited, and the signal is represented by ON and OFF.
[0006]
On the other hand, in a communication method using a serial port or a LAN port, it is necessary to use a common command on the injection molding machine side and the personal computer side, and the format of data transmitted and received differs depending on the manufacturer of the injection molding machine. This is because the data management program by the management device differs depending on the manufacturer. In other words, when an injection molding machine is provided by a certain manufacturer, a management device suitable for the injection molding machine is provided accompanying the injection molding machine.
[0007]
[Problems to be solved by the invention]
As described above, even if an attempt is made to apply a management device of a certain manufacturer to an existing injection molding machine of another manufacturer, the serial port and the LAN port cannot be used as they are. This is because, as described above, the format of data transmitted / received via the serial port or the LAN port differs depending on the maker. Even if the format can be recognized, it is not easy to rearrange the software of the management device so as to conform to the format.
[0008]
Further, if it is possible to manage an existing injection molding machine of an old type having only a printer port and an I / O port with a recent management device, it is convenient in terms of production management, but it has not been realized.
[0009]
Accordingly, an object of the present invention is to provide a data collection method and a data collection device for a molding machine that enable management by a management device without using a serial port or a LAN port.
[0010]
Another object of the present invention is to provide a data collection method and a data collection device for a molding machine that enables a management device to manage an existing injection molding machine of an old type having only a printer port and an I / O port. Is to provide.
[0011]
Still another object of the present invention is to provide a data collection method and a data collection device for a molding machine suitable for achieving the above-mentioned object while managing a plurality of molding machines.
[0012]
[Means for Solving the Problems]
According to the present invention, data is collected from the printer port of a molding machine having an output-only printer port for outputting data of a predetermined content to a printer, and the data is collected based on a predetermined management program. A data collection method is provided in which a processing device that performs processing processes collected data and displays the processed data on a display in a predetermined display form.
[0013]
Note that the processing device collects data from the printer port through a first converter for converting the data into a data format suitable for the processing device.
[0014]
In this data collection method, when the molding machine further includes an I / O port for inputting / outputting data of a type different from the data of the predetermined content, the different type from the I / O port is used. And a second converter for converting the data of the I / O port through the second converter into a data format suitable for the processing device. May also be collected.
[0015]
In the data collection method, the processing device can collect data from a plurality of molding machines and perform data processing for each molding machine.
[0016]
The data collection method further includes a first data collection terminal for rearranging the data for each of the plurality of molding machines into predetermined format data, and the processing device includes the first data collection terminal. Data may be collected through a collection terminal.
[0017]
In the data collection method, when the molding machine further includes an I / O port for inputting / outputting data of a type different from the data having the predetermined content, the processing device includes a plurality of molding machines. In order to collect data from the molding machines and perform data processing for each molding machine, the plurality of molding machines are connected to the first converters respectively connected to the plurality of molding machines, and the plurality of molding machines are connected to the first converter. The data collection may be performed through a second data collection terminal connected to the I / O port. In this case, the second data collection terminal is provided for each molding machine converted by the first converter. Are rearranged into predetermined format data, and the data of each molding machine converted by the first converter and the different types of data of each molding machine from the I / O port are It has a function to perform the timing alignment.
[0018]
According to the present invention, there is also provided processing means for collecting data from a printer port of a molding machine for outputting data having predetermined contents to a printer, and performing data processing based on a predetermined management program; Display means for processing the data collected by the processing means and displaying the data in a predetermined display form.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Before describing some embodiments of the present invention, functions of various ports provided in a molding machine, particularly an injection molding machine, will be described with reference to FIG. In FIG. 5, as described above, recent injection molding machines are provided with an I / O port, a serial port or a LAN port, and a printer port.
[0020]
The I / O port is an input / output port. As for output items, an operation signal indicating that the apparatus is currently operating, a shot signal indicating that a shot has been executed for each shot, and an injection molding machine during molding. An abnormal signal is output when an abnormality occurs, and a defective signal is output when some defect occurs in a molded product during molding. On the other hand, the input items include an operation command signal for instructing the start of molding, a peripheral device abnormality signal notified when an abnormality occurs in peripheral devices such as a molded product unloading machine, and a defective product in a defective product discriminator which is a peripheral device. There is a failure notification signal that is notified when is detected, and a stop instruction signal that instructs molding stop. These are all indicated on and off, and are almost common regardless of the injection molding machine manufacturer.
[0021]
The serial port is a port for bidirectional communication, and is a port for outputting so-called logging data to the management device side and receiving various signals from the management device side. Speaking of output items, actual data such as weighing time, operation status data indicating the operation status, data indicating the number of shots up to the current shot and the number of defective products, molding indicating what molding conditions are being performed There are condition data, abnormality content data indicating the content of an abnormality in the injection molding machine, and molding condition, that is, setting change data indicating the content when the setting value is changed. Output with the indicated data. The operation status data is data indicating the state of the injection molding machine, and data called ID (A73) is used, and A73 is indicated by a numerical value. For example, when the value of A73 is 0, it indicates that the device is operating, when it is 1, it is stopped, and when it is 2, it is abnormal.
[0022]
On the other hand, as for the input items, molding condition data sent from the management device when the molding conditions are changed, operation instruction data by ID (A73) for instructing molding start, and stop instruction data by ID (A73) for instructing molding stop. There are peripheral device error notification data that is notified when an error occurs in the peripheral device, peripheral device operation notification data that notifies the operating status of the peripheral device, and peripheral device actual data. The data about the peripheral device is sent for the following reasons. There are a case where the peripheral device and the control device of the injection molding machine are directly connected to the management device, and a case where the peripheral device is connected to the management device via the control device of the injection molding machine. In the latter case, it is not necessary to send data on the peripheral device from the management device to the control device of the injection molding machine.In the former case, however, the occurrence of an abnormality in the peripheral device is notified to the control device of the injection molding machine, and the abnormality is notified. Since it is necessary to stop the injection molding machine depending on the situation, it is necessary to send data on peripheral devices from the management device to the control device of the injection molding machine. The serial port has a higher communication speed than the printer port described below.
[0023]
The LAN port is also for two-way communication, and the contents of data to be transmitted and received are the same as those of the serial port, but the communication speed is higher than that of the serial port.
[0024]
Even if the type of data transmitted / received through the serial port or LAN port is the same for each injection molding machine maker, the data format is usually different.
[0025]
The printer port is a port dedicated to output, and the output items are almost the same as the serial port and LAN port. That is, actual data, data indicating the number of shots and the number of defective products, molding condition data, abnormal content data, and setting change data, excluding the operation status data described above, are output. The format of these output data is common regardless of the manufacturer of the injection molding machine so that any type of printer can be connected as long as the printer satisfies certain conditions. However, the data from the printer port may be serial data or parallel data.
[0026]
As is apparent from the above description, in view of the fact that an injection molding machine is provided with at least a printer port common to each company, and in some cases, an I / O port, the present invention provides data collection of the injection molding machine by using a printer port, It is characterized in that it can be performed through at least the printer port among the I / O ports. In other words, in any of the embodiments described below, it is assumed that data collection is performed on an existing injection molding machine.
[0027]
A data collection method according to the first embodiment of the present invention will be described with reference to FIG. FIG. 1 shows a case in which the data collection method according to the first embodiment is applied to a multiple-unit management system that manages a plurality of injection molding machines. For convenience, here, only two injection molding machines are used. Is shown.
[0028]
In FIG. 1, a management device 1 for a multiple-unit management system is realized by a personal computer or the like, and is connected to printer ports of two injection molding machines 2 and 3 via converters (first converters) 4 respectively. ing. The converter 4 is necessary when the data from the printer ports of the injection molding machines 2 and 3 is parallel data, and is unnecessary when the data is serial data. In other words, the converter 4 is used to convert parallel data from the printer ports of the injection molding machines 2 and 3 into serial data suitable for the management device 1. A commercially available converter of this type can be used.
[0029]
The management device 1 receives the serial data converted by the converter 4, processes the data for each injection molding machine based on a predetermined management program, saves the processing results in a built-in database, and displays the data in various display forms. It is displayed on the display 1a. The display mode will be described later.
[0030]
The management apparatus 1 has a built-in means for analyzing data from the two injection molding machines 2 and 3 and rearranging the data into certain format data. Such an analysis and rearrangement means is realized by a processing function by software. However, analysis and rearrangement processing by software imposes a new load on the management device 1. The analysis and rearrangement processing is based on the fact that the data output from the printer port is binary data, and the management device 1 needs to convert the received binary data into data in a format suitable for internal processing. Of course, as described above, such a load is much smaller than the load of recognizing the format of data from the serial port or the LAN port and reconfiguring the software. No new load has occurred.
[0031]
Therefore, in order to reduce the load on the management apparatus 1, it is desirable that the analysis and rearrangement processing on the data from the two injection molding machines 2 and 3 be performed before the data is input to the management apparatus 1.
[0032]
FIG. 2 shows a second embodiment including a data collection terminal 5 (first data collection terminal) for reducing the load on the management device 1. In FIG. 2, as in the first embodiment, the converter 4 converts parallel data from the printer ports of the injection molding machines 2 and 3 into serial data. Each of the serial data from the converter 4 is analyzed and rearranged into predetermined format data by the data collection terminal 5. The management device 1 receives the serial data from the data collection terminal 5, processes the data for each injection molding machine based on the management program, saves the processing result in a built-in database, and displays it on the display 1a in various display forms. . The display mode is the same as that of the first embodiment, and will be described later.
[0033]
FIG. 3 shows a data collection method according to the third embodiment of the present invention. In the third embodiment, not only data from a printer port but also data from an I / O port provided in an injection molding machine are collected and processed to enable more detailed management. 3, the same elements as those in FIG. 1 are denoted by the same reference numerals.
[0034]
In FIG. 3, a management device 1 is connected to printer ports of two injection molding machines 2 and 3 via a converter 4. In addition, the management device 1 is connected to the I / O ports of the two injection molding machines 2 and 3 via the converter 6 (second converter). The converter 6 is for converting the signal from the I / O port described above into a signal suitable for the management device 1, but may be built in the management device 1.
[0035]
As described above, signals from the I / O port are an operation signal, an abnormal signal, a defective signal, a shot signal, and the like, and data represented by these signals cannot be acquired from the printer port in many cases. In other words, these signals indicate the state by the presence or absence of a voltage, that is, on and off. For example, when the operation signal changes from on to off and the abnormal signal is off, it is determined that the injection molding machine has stopped. Is done. The main role of the converter 6 is to transmit a change in the voltage of a certain signal to a predetermined port (address), whereby the management device 1 can determine which signal has changed. That is, the management device 1 sets the value 0, 1 or the like to the numerical value A73 of the ID (A73) determined by checking the state of the port.
[0036]
The management device 1 receives the serial data converted by the converter 4 and the I / O signal converted by the converter 6, processes each injection molding machine based on the management program, and stores the processing result in a built-in database. Or displayed on the display 1a in various display forms.
[0037]
In any case, for example, the operation signal and the abnormal signal from the I / O port can be used for displaying the state of each color in the display mode of FIG.
[0038]
The management apparatus 1 has a built-in means for analyzing data from the two injection molding machines 2 and 3 and rearranging the data into a certain format data as described in the first embodiment. In the third embodiment, the management device further includes a means for aligning the timing because there is a timing difference between the I / O signal from the converter 6 and the serial data from the converter 4. are doing. Such means is realized by a processing function by software. However, the analysis and rearrangement processing and the timing adjustment processing by software impose a new load on the management device 1.
[0039]
Therefore, in order to reduce the load on the management apparatus 1, the analysis and rearrangement processing for the serial data from the two injection molding machines 2, 3 and the timing adjustment processing of the I / O signal and the serial data are performed on the management apparatus 1. It is desirable that it be executed before input.
[0040]
FIG. 4 shows a fourth embodiment including a data collection terminal 7 (second data collection terminal) for reducing the load on the management device 1. In FIG. 4, the parallel data from the printer ports of the injection molding machines 2 and 3 are converted into serial data by the converter 4 as in the first embodiment. Each of the serial data from the converter 4 is analyzed and rearranged into predetermined format data by the data collection terminal 7. On the other hand, I / O signals from the I / O ports of the injection molding machines 2 and 3 are respectively converted into signals suitable for the management device 1 by the data collection terminal 7, and the timing is adjusted with the serial data from the converter 4. I do. That is, the data collection terminal 7 receives the serial data (logging data) from the converter 4 on a certain injection molding machine and the I / O signal (defective signal, shot signal, etc.) from the same I / O port on the injection molding machine. ) Are sent to the management device 1 at the point in time when the above is completed. The data obtained from the operation signal and the abnormal signal is sent to the management device 1 when the state changes (for example, a change from operation to abnormal).
[0041]
The management device 1 receives the serial data and the I / O signal from the data collection terminal 7, processes the data for each injection molding machine based on the management program, saves the processing results in a built-in database, and displays the data in various display forms. It is displayed on the display 1a.
[0042]
Next, with reference to FIGS. 6 to 9, a management apparatus for a multiple-unit management system proposed by the present applicant (Japanese Patent Application No. 2001-193234) will be described. The management device according to the above proposal is applied to a system for managing a plurality of injection molding machines as shown in FIG.
[0043]
In FIG. 6, a plurality of injection molding machines 10-1 to 10-n are installed in the same place, and these are collectively managed by a management device 20 with a display device. That is, the management device 20 is connected to each control device in the injection molding machines 10-1 to 10-n, and receives various signals from various sensors installed in each of the injection molding machines 10-1 to 10-n. Information is received via each control device, the received information is processed for each injection molding machine based on a built-in management program, and the processing result is stored in a built-in database and displayed on a display device as a management screen. Depending on the type of information, the received raw information is directly stored in the database.
[0044]
Next, there are a plurality of types of management screens displayed on the display device to indicate the operation status of each injection molding machine in the management device 20, and four examples will be described.
[0045]
FIG. 7 is an operation status screen that displays the operation status of a plurality of injection molding machines in real time. In this operation status screen, the operation statuses of a plurality of injection molding machines are collectively displayed on a single screen in real time for all the units (here, No. 1 to No. 30) in a screen division format. For example, referring also to FIG. 8 which is an enlarged view of the No. 9 machine, the number of the No. 9 machine is shown at the upper left, the count value C1 (here 17) of the molding condition change (setting change) counter is shown at the upper right, and 24 is shown at the right side. The time operation status graph shows the number of shots (529) and the cycle time (14.9 seconds) on the lower side. Here, the molding condition change counter is a counter that counts how many molding conditions (settings) have been changed from the start of molding to the present. This counter is provided in the management device 20. The control device of each injection molding machine is provided with a means for detecting a change in molding conditions, and the management device 20 receives the detection result from each control device and counts each, and displays the count result for each unit on a display device. Let it. In the management device 20, this display value can be reset as needed.
[0046]
The 24-hour operation status graph is a graph in which the operation status of the injection molding machine in the past 24 hours from the present time is color-coded and displayed as a single first bar graph B1. The operation status is defined by four types: operation, normal stop (during standby), stop due to abnormality occurrence, and power-off. The four types of status are color-coded and displayed according to the elapsed time from 24 hours before to the present time. Is done. Here, the operation is blue, the normal stop is yellow, the stop due to the occurrence of an abnormality is red, and the power supply is turned off in gray. For convenience, in FIG. 8, blue is narrow hatching falling to the right, yellow is vertical hatching, and red is right hatching. Thick hatching, gray is shown with thick hatching down to the left. In addition, the lowermost end of the first bar graph B1 is 24 hours ago, and the uppermost end is the present time. For example, a normal stop is performed from the past 24 hours to 12 hours ago, and it is in operation from the past 12 hours to the present time. If so, the first bar graph B1 is displayed in yellow in the lower half and blue in the upper half.
[0047]
In the above proposal, furthermore, the appearance of the injection molding machine is displayed as an icon image in the divided screen of each unit, and the background is based on the operation, the normal stop, and the occurrence of the abnormality to indicate the current operation status. The four types of stop and power-off are displayed in the same corresponding color relationship as the color classification in the first bar graph B1. That is, assuming the same as the above example, the background color is blue.
[0048]
By looking at such an operation status screen, the operator or the administrator can know at a glance which unit was in what operation status in the past 24 hours. The value of 24 hours is usually a fixed value, but may be variable.
[0049]
By the way, the management device 20 can display a general graph screen which shows the operation status of only the corresponding car in detail by clicking a specific portion in the divided screen of each car in the above-mentioned operation status screen on the display device.
[0050]
FIG. 9 is an example of a general graph screen. In this general graph screen, the change status of quality data for 24 hours, the presence or absence of an abnormality, and the presence or absence of a setting change indicate the time for each unit (here, Unit 10). It is displayed on one screen along the axis. In FIG. 9, the uppermost graph is a line graph showing the change in the cumulative value of the number of shots, and a plurality of vertically extending lines, for example, the line L1, was interrupted at around 18:00 (abnormality occurred). It indicates that. The “status” of L2 is the same as the display of the operation status described above, and is defined by four types of operation, normal stop (during standby), stop due to occurrence of an abnormality, and power-off, for 24 hours. The status is displayed in different colors according to the time. The “condition name” of L3 is a graph showing the time when the molding condition is changed, that is, when the condition name for each molded article is changed, the color is changed and the time is changed. In other words, this is changed when the molded article changes, and is displayed by color. However, the color itself has no meaning, and the time when the color changes is significant. On the other hand, the “item” of L4 is a graph that changes the color when the condition item in the molding condition is changed and displays the change with the time. For example, a color is changed when an injection condition, a mold opening condition, or the like is changed, and this also has a meaning at a time when the color changes rather than the color itself. Therefore, the colors of “condition name” and “item” are different from “state”, and four or more colors are prepared.
[0051]
Further, the graph in the first row of L5 shows the elapsed time of the “filling time” of the display item shown in the display item selection column on the lower side of FIG. 9, and the second row similarly shows the time of the “minimum cushion position”. Show progress. The graph in the third row shows the “holding pressure completion position”, and the fourth and fifth rows show the lapse of time in the “V / P switching position” and the “position before filling”, respectively.
[0052]
In the above proposal, on the right side of the summary graph screen, the operation status of the relevant unit in the past 24 hours is further classified into the same color as the first bar graph B1 by the second bar graph B2 at an operation rate of 0 to 10%. , And 24 hours. FIG. 9 shows that the operation rate in the past 24 hours is 28%, and the "time display" shown in the display item selection column at the bottom of FIG. Is displayed. Note that the number in the “time display” column can be arbitrarily changed. In other words, “date and time” and “time display” shown in the display item selection column can be set arbitrarily. Here, the numerical value of 24 hours from 10:00 on September 4, 2000 is set. As shown at the top of FIG. 9, 24 hours from 10:00 on September 4, 2000 to 10:00 on September 5, 2000 is displayed. If the number "12" is entered in "time display", the operating rate for the past 12 hours based on 12 hours is displayed in the second bar graph B2. In this case, the graphs or items in the first to eighth rows in FIG. 9 are also shown for the past 12 hours. According to such a second bar graph B2, it is possible to display the operation rate from an arbitrary time at an arbitrary time.
[0053]
The general graph screen of FIG. 9 is linked to the operation status screen of FIG. 7, and is displayed by clicking a specific portion (icon) of each unit on the operation status screen of FIG.
[0054]
In the present invention, the management device 20 according to the above proposal is used as the management device 1. For the above-mentioned reason, at least the data from the printer port out of the printer port and the I / O port is used, so that FIG. A display form as shown in FIG. 9 can be realized. For example, referring to FIG. 9, the graphs L1 and L2 and the bar graph B2 can be displayed in a graph using I / O signals from the I / O port, and the graphs L3 to L5 can be displayed from the printer port. Can be displayed in the form of a graph based on the above data.
[0055]
It goes without saying that the present invention is applicable not only to injection molding machines but also to molding machines in general, for example, molding machines such as extrusion molding machines. The management device 1 is a management device for a multiple management system, but can be used as only one management device. In this case, the operation status screen as described with reference to FIG. 7 is unnecessary, and the display is performed by the general graph screen of FIG.
[0056]
【The invention's effect】
According to the data collection method of the present invention, even when the format of data at a serial port or a LAN port of an existing molding machine is unknown, or even when these ports are not provided, the quality data of the molding machine is utilized using a printer port. Can be collected on the management device side.
[0057]
The programming change made to the management device to realize the present invention is much easier than the programming change made after analyzing the data format in the serial port or LAN port.
[0058]
When a plurality of injection molding machines are installed, a printer is connected and printed for each injection molding machine in order to print quality data and molding conditions. In the present invention, however, a plurality of injection molding machines are provided in one management apparatus. Since a molding machine can be connected, data of a plurality of injection molding machines can be printed by one printer connected to the management device.
