Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mold management system in a molding machine, particularly an injection molding machine.
[0002]
[Prior art]
The mold in the injection molding machine is made for each molded product and is expensive, so its maintenance is important. In other words, the mold has a lifetime, and as the number of shots increases, the end of the lifetime approaches. Therefore, maintenance is performed such that the period of regular maintenance is determined by the number of shots, or replacement is performed before the end of the service life.
[0003]
Until now, mold maintenance has been carried out as follows.
[0004]
1. The number of shots of the mold is measured at the shipping destination of the injection molding machine. That is, the number of daily shots is regularly recorded by the operator, and is input and stored in a PC (personal computer) or the like as mold maintenance information.
[0005]
2. A system that makes it possible to automatically record the number of shots of an injection molding machine by attaching a recording medium to a mold at a shipping destination that makes full use of information technology, and automatically collects information on this recording medium as maintenance record information of the mold Is making.
[0006]
[Problems to be solved by the invention]
In any case, the maintenance so far is to manage the number of shots for one mold. However, as will be described later, the mold is composed of a plurality of parts, and each part does not have the same life. And in a factory equipped with a plurality of injection molding machines in order to mold many of the same molded product, when a sudden failure occurs in a mold of an injection molding machine, for example, when a failure occurs in a part with a mold, In some cases, a part is replaced with the same part removed from another mold. In this case, a part that contributes to molding of another shot number is mixed in a mold that contributes to molding of a certain number of shots. In other words, in the above case, it is impossible to grasp the period of regular maintenance and the lifespan, and it is not possible to deal with die failure only when the die actually fails or a molding defect due to the die occurs. become. Suddenly, when a failure occurs in the mold or a molding defect due to the mold occurs, the mold shifts greatly from the production plan, causing problems such as missing parts.
[0007]
SUMMARY OF THE INVENTION An object of the present invention is to provide a mold management system for realizing preventive maintenance against a mold failure by automatically managing a mold for each part.

DETAILED DESCRIPTION OF THE INVENTION
Before describing the embodiments of the present invention, the embodiments described below are specialized in application to injection molding machines, and in particular, a plurality of management systems that collectively manage a plurality of injection molding machines It is assumed that they are applied in combination. Therefore, first, a management system for a plurality of injection molding machines will be described.
[0017]
FIG. 3 shows the configuration of a multiple-unit management system for an injection molding machine. In FIG. 3, a plurality of injection molding machines 10-1 to 10-n are installed in a certain factory 100, and the plurality of injection molding machines 10-1 to 10-n includes a management device 20. Are managed collectively. That is, the management device 20 is connected to each control device in the injection molding machines 10-1 to 10-n, and various kinds of sensors from various sensors installed in 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 processed result is stored in a built-in memory and displayed on a display as a management screen. Of course, depending on the type of information, the received raw information may be stored in the memory as it is.
[0018]
In particular, this multi-unit management system is used when there is an injection molding machine manufacturer (or the manufacturer's management center) or another factory managed by a similar multi-unit management system at a remote location away from the factory 100. Each manufacturer or another factory can be configured to acquire specific information in the management device 20 in the factory 100 by accessing a Web server via a communication network such as the Internet. Alternatively, even when a plurality of management systems in the factory 100 and a plurality of management systems in another factory can be connected via a network such as a LAN (Local Area Network), specific information can be mutually acquired. Can be configured.
[0019]
As is well known, the Web server generally operates according to HTML. However, for example, it may be one that can handle Compac HTML data that defines a Web service for mobile phones. In any case, this type of Web server includes a processor and a memory, and the operation of the Web server is realized by the processor executing a program stored in the memory. The memory is also a temporary storage location for data output while the processor is executing a program.
[0020]
Of course, in order to prevent access from a completely unrelated communication terminal apparatus, an ID number and a password are given to the communication terminal apparatus that can access the Web server in advance.
[0021]
Next, four examples of a plurality of types of screens displayed to represent the management status of each injection molding machine in the management apparatus 20 of the multiple-unit management system will be described.
[0022]
FIG. 4 is an operation status screen that displays the operation status of a plurality of injection molding machines in real time. On this operation status screen, the operating status of a plurality of injection molding machines is 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 to FIG. 5 showing the enlarged view of No. 9, the number of the No. machine is shown in the upper left, the molding condition change display section C1 in the upper right shows the count value of the molding condition change counter (here, 17), the right side A bar graph B1 shows a 24-hour operation status graph, and a shot number (529) and a cycle time (14.9 sec) are displayed on the lower side.
[0023]
Here, the molding condition change counter is a counter that counts how many times the molding conditions have been changed from the start of molding to the present. This counter is provided in the management apparatus 20. The control device in each injection molding machine is provided with means for detecting a change in molding conditions, and the management device 20 receives each detection result from each control device and counts each, and the count result for each machine is displayed as a molding condition change display unit. Display on C1. In the management device 20, this display value can be reset as necessary.
[0024]
The 24-hour operation status graph is a single first bar graph B1 in which the operation status of the injection molding machine in the past 24 hours from the current time is color-coded. The operation status is defined by four types: operation, normal stop (during standby), stop due to abnormality, and power-off, and the four types of status are displayed in different colors according to the passage of time from 24 hours ago to the present time. Is done. Here, operation is shown in blue, normal stop is yellow, stop due to abnormality is red, and power off is shown in gray. In FIG. 5, for convenience, blue is fine hatching with lower right, yellow is vertical stripes, red is lower right Coarse hatching and gray are shown with a left-down hatching. In addition, the lowermost end of the first bar graph B1 indicates 24 hours ago, and the uppermost end indicates the current time point. If there is, the first bar graph B1 is displayed with the lower half in yellow and the upper half in blue.
[0025]
Furthermore, in this example, the appearance of the injection molding machine is schematically displayed in the divided screen of each unit, and the background is based on the operation, the normal stop, and the occurrence of an abnormality to indicate the current operation status. The four types of stop and power off are displayed in the same color relationship as the color classification in the first bar graph B1. That is, if it is the same as the above example, the background color is blue.
[0026]
By looking at such an operation status screen, the operator or administrator can know at a glance which unit has been in what operating status in the past 24 hours. The numerical value of 24 hours is usually a fixed value, but may be variable.
[0027]
By the way, the management device 20 displays a general graph screen showing in detail the operating status of only the corresponding unit by clicking on a specific location (icon on the screen) in the divided screen of each unit on the above operating status screen on the display. It is possible.
[0028]
FIG. 6 shows an example of a summary graph screen. In this summary graph screen, the change status of quality data for 24 hours, presence / absence of abnormality, and presence / absence of setting change across time for each unit (here, No. 10). It is displayed on one screen as an axis. In FIG. 6, the uppermost graph is a line graph showing changes in the cumulative value of the number of shots, and a plurality of vertically entering lines, for example, the line L1, has a molding interruption (occurrence of anomaly) around 18:00. It shows that. The “state” of L2 is the same as the display of the operation status described above, and is defined by four types: operation, normal stop (during standby), stop due to abnormality occurrence, and power off, and 24 hours worth The status is displayed in different colors according to the time. The “condition name” of L3 is a graph showing the change time when the molding condition is changed, that is, when the condition name for each molded product is changed, the color is changed. In other words, this is changed when the molded product changes, and is displayed by color, but the color itself is not meaningful, but is meaningful at the time when the color changes. On the other hand, the “item” in L4 is a graph that displays the change in color with time when the condition item in the molding condition is changed. For example, the color is changed when an injection condition, a mold opening condition, or the like is changed, and this is also more meaningful at the time when the color changes rather than the color itself. For this reason, four or more colors are prepared for “condition name” and “item”, unlike “status”.
[0029]
Further, the first graph of L5 shows the elapsed time of “filling time” of the display item shown in the display item selection column on the lower side of FIG. 6, and the second row similarly shows the time of “minimum cushion position”. Show progress. The third graph shows the “holding pressure completion position”, and the fourth and fifth graphs show the elapsed time of “VP switching position” and “pre-filling position”, respectively.
[0030]
In this example, the operation status of the unit in the past 24 hours is further displayed on the right side of the general graph screen with a numerical value indicating 24 hours by the second bar graph B2 at an operation rate of 0 to 100%. ing. FIG. 6 shows that the operating rate of the past 24 hours is 95%, and the operating rate calculation is based on the “time display” portion shown in the display item selection column on the lower side of FIG. The number is displayed. The numbers in the “time display” column here can be arbitrarily changed. In other words, the “date and time” and “time display” shown in the display item selection field can be arbitrarily set, and here, a numerical value of 24 hours from 10:00 on September 4, 2000 is set. As shown in the uppermost part of FIG. 6, 24 hours from 10:00 on September 4, 2000 to 10:00 on September 5, 2000 are displayed. If the number “12” is entered in “time display”, the operation 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 stages in FIG. 6 are also shown for the past 12 hours. According to such 2nd bar graph B2, the operation rate from arbitrary time of arbitrary time can be displayed.
[0031]
FIG. 7 shows an example of the setting history screen. In this setting history screen, the history of setting change is 1 for each unit (here, No. 10), together with the changed item, the setting value before and after the change, and the change date and time. Displayed on the screen.
[0032]
FIG. 8 is an example of an abnormality history screen. In this abnormality history screen, the history of occurrence of abnormality is displayed on one screen for each unit (here, No. 10) together with the item of abnormality, the occurrence date and time, and the release date and time. .
[0033]
As described above, the general graph screen of FIG. 6 is linked to the operation status screen of FIG. 4 and is displayed by clicking a specific location (icon on the screen) of each unit on the operation status screen of FIG. It is like that. Further, the setting history screen of FIG. 7 and the abnormality history screen of FIG. 8 are linked to the operation status screen of FIG. 4 or the general graph screen of FIG. 6, respectively, and the operation status screen of FIG. 4 or the general graph screen of FIG. It is displayed by clicking a specific part (icon on the screen).
[0034]
This multi-unit management system is a system for managing the number of shots of an injection molding machine in real time and managing how many molded products are molded. In this multi-unit management system, at least the following information is managed.
[0035]
1) Mold name and number of shots
2) History of various abnormalities and setting changes that occurred in the molding machine
3) Molding conditions for molding
The above-mentioned multiple-unit management system is proposed by the present inventor, for example, in “Remote Monitoring Method Using Communication Network” (2001 Japanese Patent Application No. 193119).
[0036]
The mold management system according to the present invention is connected to the above-described multiple-unit management system via communication means, and receives data related to at least the mold and the number of shots in each injection molding machine and performs management related to the mold. Before describing the mold management operation, an example of a mold to be managed according to the present invention will be described with reference to FIG.
[0037]
FIG. 9 shows an example of a mold for a disk molding mold. In FIG. 9, reference numeral 12 denotes a fixed-side mold assembly that is attached to a fixed platen (not shown) by a bolt (not shown). The mold assembly 12 includes a base plate 15, a disk plate 16 attached to the base plate 15 with bolts 17, and is disposed in the base plate 15 so as to face the fixed platen, and locates the base plate 15 with respect to the fixed platen. 23, and a sprue bush 24 disposed adjacent to the locating ring 23.
[0038]
A die 28 is formed at the front end (the left end in the figure) of the sprue bush 24 so as to face the cavity space C. The sprue 26 is connected to the die 28 and allows resin injected from an injection nozzle of an injection device (not shown) to pass therethrough. Is formed.
[0039]
On the other hand, 32 is a movable side mold assembly attached to a movable platen (not shown) by a bolt (not shown). The mold assembly 32 is arranged so as to face the movable platen in the base plate 35, the intermediate plate 40 attached to the base plate 35 with bolts 37, the disk plate 36 attached to the intermediate plate 40 with bolts 42, and the base plate 35. A cylinder 44 mounted on the base plate 35 with a bolt 45, and moved forward and backward (moved in the right and left directions in the figure) by the cylinder 44, and has a cut punch 48 having a shape corresponding to the die 28.
[0040]
Further, a concave portion for forming the cavity space C is formed on the surface of the disc plate 36 facing the disc plate 16. Therefore, when the mold clamping device (not shown) is operated to move the movable platen to the fixed platen side, and the mold is closed and clamped, the disk plate 36 is pressed against the disk plate 16 and the cavity space C is formed.
[0041]
In the cylinder 44, a piston 51 formed integrally with the cut punch 48 is disposed so as to freely advance and retract. Further, a cut punch return spring 52 is disposed in front of the piston 51 (rightward in the figure), and the piston 51 is pushed rearward by the bias of the cut punch return spring 52.
[0042]
Accordingly, when the piston 51 is moved forward (moved to the right in the drawing) by a driving means (not shown) in the mold clamping state, the cut punch 48 is moved forward and enters the die 28. As a result, the resin in the cavity space C can be perforated to remove the inner diameter of the disk substrate.
[0043]
By the way, the mold assemblies 12 and 32 are centered by the guide posts 54. For this purpose, four guide post holes 53 (two guide post holes 53 are shown in the figure) are formed on the base plate 15 concentrically with respect to the center of the mold assembly 12 by grinding. The guide post 54 is attached to the guide post hole 53 so as to protrude toward the mold assembly 32 by press-fitting and fixed to the base plate 15 by bolts 55.
[0044]
On the other hand, a guide bush hole 56 is formed by grinding at a position corresponding to the guide post hole 53 of the intermediate plate 40. A guide bush 57 is attached to the guide bush hole 56 by press fitting, and the guide post 54 can be guided by the guide bush 57. When the mold is closed, the mold assemblies 12 and 32 can be aligned by causing the guide post 54 to enter the guide hole of the guide bush 57 via a ball bearing portion (not shown).
[0045]
Temperature control channels 61 and 62 are formed in the disk plates 16 and 36, respectively. By supplying and circulating a medium such as water, oil, air, etc. to the temperature control channels 61 and 62, the disk plates 16, 36 can be cooled.
[0046]
The mold management system according to the present invention manages the mold as described above for each part.
[0047]
FIG. 1 shows a configuration when a mold management system according to the present invention is connected to a plurality of management systems via a communication network such as a LAN. Here, the mold management system is connected to a plurality of management systems consisting of injection molding machines 10-1 to 10-n and a plurality of management systems consisting of injection molding machines 10-1 'to 10-n'. It shall be. The number of the injection molding machine in this case is, for example, 10-1 for “No. 1”, 10-n for “No. n”, 10-1 ′ for “(n + 1) No.”, and 10-n ′ for “No. The number “n + n” is given. The mold management system is realized by a management device 1 such as a personal computer. The management device 1 has a memory for receiving and storing data relating to the number of shots for each injection molding machine from each of the plurality of management systems. , Output means such as a display, and input means such as a keyboard and a mouse.
[0048]
In the memory of the management apparatus 1, a mold management table as shown in FIG. 2 is created and registered in advance. This management table is created for each mold in operation in the injection molding machine. In order to create a management table, a unique management number is assigned in advance to each of a plurality of parts constituting the mold. The management numbers of these parts are different even for the same type of mold.
[0049]
Speaking of the disk molding die described in FIG. 9, the base plates 15 and 35, the disk plates 16 and 36, the locating ring 23, the sprue bush 24, the intermediate plate 40, the cylinder 44, the cut punch 48, the piston 51, and the cut punch return. A management number is assigned in advance to the spring 52, the guide post 54, the guide bush 57, and the like.
[0050]
In FIG. 2, the management table shows the part name, its management number, the total number of shots used for molding up to the present time, and each part for each part constituting the mold of the injection molding machine in operation. This represents a correspondence relationship between the lifespan shot obtained by converting the component life calculated in advance into the number of shots, and the number of maintenance shots on which maintenance is to be performed on the component. In FIG. 2, “10” is entered as the machine number of the injection molding machine, “die for disk molding” is entered as the mold name, and “base plate”, “disk plate”, “locating ring”, “sprue bush” are entered as the part names. ”,“ Intermediate plate ”,“ cylinder ”, and others (not shown) are input. In addition, the management number, the number of life shots, and the number of maintenance shots are input for each column, and here, when a part is replaced, the replacement date is also input. The exchange date is accumulated and registered, and all the registered information is displayed so that the number of exchanges can be known.
[0051]
This management table can display a die management table in a desired injection molding machine by designating the machine number of the injection molding machine on the display of the management apparatus 1, and changes the contents of each column by input means. However, the total number of shots is updated for each shot based on the shot number data transmitted from the multiple-unit management system.
[0052]
The management apparatus 1 collectively manages a management table for a large number of molds in a large number of injection molding machines managed by two multiple-unit management systems, and updates the total number of shots for each part in each management table for each shot. When the total number of shots of a certain part reaches the number of maintenance shots set for this certain part, a warning is displayed on the display. The form of the alarm display is a form in which, for example, a management table including the corresponding part is forcibly displayed, and the item of the total shot number, for example, is displayed in red and blinking in the corresponding part column in the management table. However, this display form is arbitrary. When there is such a display, the operator can confirm the name of the blinking part of the mold according to the display content, and can know that the part has come to a time that requires maintenance.
[0053]
By the way, the management apparatus 1 further stores in the memory a spare part table registered for all spare parts prepared as spare parts, in addition to the management table related to the active mold. This spare parts table is exactly the same as the management table in terms of content, with the only difference that mold parts that are not in operation are registered. That is, in this spare parts table, the name, the management number, the total number of shots used for molding up to the present time, and the part life calculated in advance for each part are used as the number of shots. The correspondence between the number of converted life shots and the number of maintenance shots to be maintained and the replacement time is expressed. In the spare part table, there is an item for registering the total number of shots because there is a case where the spare part is temporarily used in a certain mold and then again placed in a standby state as a spare part. That is, the number of shots during this temporary use is held as the total number of shots. When a completely new part is prepared and replaced instead of the part managed in the spare part table, the management number, the number of life shots, and the number of maintenance shots are input to the management table. On the other hand, when a completely new part is put on standby as a spare part, a new item relating to the new part is registered in the spare part table and necessary data is input.
[0054]
In both the management table and the spare parts table, the management number information indicating the management number includes name information indicating the name, total shot number information indicating the total shot number, life shot number information indicating the life shot number, and alarm shot. Alarm shot number information indicating the number of maintenance shots, maintenance shot number information indicating the number of maintenance shots, and replacement time information indicating the replacement time. As a result, when the part in the mold being managed is replaced with a part registered in the spare part table and the management number of the replaced part is input, the management apparatus 1 refers to the spare part table. The name information associated with the management number entered in the spare parts table includes name information, total shot number information, life shot number information, maintenance shot number information, and replacement time information in the replaced parts column in the management table. And the total shot number information, life shot number information, maintenance shot number information, and replacement time information are automatically updated.
[0055]
For example, in FIG. 2, assuming that 3 locating rings have been exchanged, name information, total shot number information, life shot number information, maintenance shot number information in the locating column previously managed in the management table, The replacement time information is moved to the spare parts table. Instead, the name information, total shot number information, life shot number information, maintenance shot number information, and replacement time information in the locate ring column registered in the spare part table are managed. Transferred to the table. As a result, for example, if this exchanged locating ring is already used for a certain number of shots S1, if molding is resumed after the exchange is completed, it is added to the number of shots S1, which is an item of the total number of locating shots The obtained value is updated as the total number of shots.
[0056]
According to such a configuration, regardless of when and what parts are replaced in any mold, the total number of shots related to the replacement parts can be reliably grasped, and the operator can be informed of the maintenance time and the service life accurately. Can do.
[0057]
In the management apparatus 1, in addition to the display of the management table as shown in FIG. 2 on the display, the history of how the specific mold has been used so far, that is, which parts are set by the input means. A history such as when it was exchanged can be displayed. The management apparatus 1 also receives an abnormality history for a specific mold, that is, a history of what abnormality has occurred in which parts so far, and receives data for the abnormality history screen described in FIG. It can also be displayed using this.
[0058]
As apparent from the above description, the following management can be realized by the mold management system according to the present invention.
[0059]
1) Receive shot data of molds for each injection molding machine from each of the multiple-unit management systems.
[0060]
2) In the mold management system, the mold is managed for each part, and the shot number data of the item 1) is added to each part. With this mechanism, the number of molding shots is managed for each part of the mold.
[0061]
3) In the mold management system, settings for preventive maintenance, that is, the number of maintenance shots and the number of life shots can be set for each part in advance, and the actual value and the set value are compared in real time. When reaches the set value, alarm processing is performed. In addition to the example described above, the alarm processing can be performed by displaying a mold picture on the display screen in a 3D (dimension) form or 2D form, changing the color of the corresponding part, or mailing the operator. Is possible. Since this alarm process can be arbitrarily set according to the customer's request, any display form may be used.
[0062]
4) Even if a part is transferred from one mold to another, by inputting the part management number, the shot number data so far can be managed without disappearing.
[0063]
5) In the mold management system, the history of an arbitrary mold can be displayed by the operator, and the past maintenance record can be maintained.
[0064]
6) The abnormality history can be displayed by calling the abnormality history data related to a specific mold from the mold management system to the multiple-unit management system of the injection molding machine by the communication means.
[0065]
7) The mold management system shown in Fig. 1 is installed at the manufacturer of the injection molding machine or its management center, and a plurality of multi-unit management systems are held at the customer's factory to which the injection molding machine is delivered. Then, it is possible to provide the customer with a service for automatically preventing and maintaining hundreds of molds owned by the customer.
[0066]
【The invention's effect】
According to the present invention, the following effects can be obtained.
[0067]
a) Preventive maintenance can be realized for each part of the mold.
b) The maintenance history of the mold can be easily grasped.
c) A history of occurrence of abnormality during the molding operation of the mold can be easily grasped.
d) Even if a part of a certain mold is diverted to another mold, the data on the number of shots is managed as it is without being erased because of management in parts.
