Description

Technical Field

[0001] This invention relates to an action setting device that makes it easy to set the action of the ejector in an injection molding machine, and to an injection molding machine. Background Technology

[0002] In injection molding machines, the ejector actuates (also known as "ejector action") when the injection-molded part is removed from the mold, demolding and removing the part from the mold. Ejector action is performed by protruding the ejector pin towards the mold while the mold is open. However, sometimes it is difficult to remove the part with a single ejector pin protrusion; in most cases, the ejector pin protrusion action is repeated. Multiple action modes are set to perform this ejector action to reliably remove the molded part.

[0003] Because the ejector action of an injection molding machine is complex, its settings are cumbersome. To address this complexity, for example, Patent Document 1 provides an ejector control device that allows for easy setting of the ejector action mode. Specifically, it proposes a technique for setting the ejector action mode on a process-by-process basis by comprising the following units: a process setting unit that sets the target arrival position of the ejector's movement and the speed of movement up to that target position for each process; a process sequence setting unit that sets the action sequence of multiple processes set by the process setting unit; and a process execution unit that executes the ejector's movement according to the action sequence set by the process sequence setting unit. This technique believes that by dividing the ejector action mode into multiple processes and setting its action for each process, it is possible to set and modify the action on a process-by-process basis, making the setting of the ejector action mode easier. Furthermore, it facilitates the modification of already set ejector action modes, allowing for simple setting and modification of the ejector action mode based on the shape and material of the molded product.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2008-6785 Summary of the Invention

[0007] The problem the invention aims to solve

[0008] In the technology of Patent Document 1, it is necessary to set four items for each process, namely, start conditions, delay timer, position, and speed, based on the set number of processes. In the prior art represented by Patent Document 1, the setting of the ejector action of the injection molding machine is complicated and must be operated in a complicated setting display screen.

[0009] The present invention was made to solve such conventional problems, and its object is to provide an action setting device and an injection molding machine that makes it easier to set the ejector action in an injection molding machine by eliminating the complexity of setting the ejector action and the associated complicated screen.

[0010] Solution for solving the problem

[0011] The motion setting device of this invention is a device for setting the motion of an ejector, which has a setting display screen in the form of a touch panel. It performs the following steps: First, touching any point on the chart displayed on the setting display screen to input the motion sequence and position of the ejector; Second, based on the input motion position, inputting motion parameters including the ejector's motion speed, motion position, motion time, and motion mode; and Third, displaying the input motion position and motion parameters on the chart of the setting display screen and displaying numerical values ​​on the numerical display section. The motion position and motion parameters of each motion set in the first to third steps are displayed on the chart and displayed numerically on the numerical display section.

[0012] According to the present invention, the action position and action parameters of each set action are displayed in a graph on the setting display screen and in numerical value on the numerical display unit. Therefore, an image of the ejector action can be easily formed through the graph, and the numerical value of its action parameters can be confirmed. This setting display screen is a touch panel capable of displaying the required information and allowing for intuitive operation, thus facilitating easy input of ejector action parameters. In particular, settings can be made by direct touch on the graph of the setting display screen, enabling visual settings.

[0013] In the motion setting device according to the present invention, the setting display screen includes an execution unit that executes the set motion parameters. According to the present invention, the set motion parameters can be executed by this execution unit.

[0014] The motion setting device according to the present invention includes: a correction function that corrects for locations mistakenly input due to touch operation; and a setting device for fine-tuning the input motion position and motion parameters. According to the present invention, the correction function for correcting mistakenly input locations enables changes to the motion position within a narrow range, which is a drawback of touch operation. Fine-tuning of the motion position and motion parameters can be performed using a setting device that allows direct input of numerical values.

[0015] In the motion setting device of this invention, the chart is saved as forming conditions. According to this invention, the motion parameters displayed in the chart can be managed as forming conditions. By recalling the managed forming conditions from the saved memory, previously set motion parameters can be used flexibly, making the setting process easier.

[0016] In the motion setting device of this invention, the chart and the numerical display are linked. According to this invention, the chart and the numerical display are linked so that a value input by touch in the chart is displayed numerically, or the chart is displayed based on the numerically displayed value.

[0017] The motion setting device of the present invention has an editing mode for editing the motion position and the motion parameters. When the editing mode is set, the portion of the motion position or motion parameter to be edited is displayed in a strip. According to the present invention, by displaying the portion of the motion position or motion parameter to be edited in a strip, it is easy to know the part to be edited and the setting can be easily performed.

[0018] In the motion setting device according to the present invention, when the ejector is moved forward, the maximum forward travel limit is displayed in color on the graph. According to the present invention, displaying the maximum forward travel limit in color on the graph prevents exceeding the maximum forward travel limit setting.

[0019] The motion setting device of this invention has the function of copying and pasting the motion position and motion parameters displayed in the chart. According to this invention, such a function can save the effort of setting the motion position and motion parameters.

[0020] The motion setting device of the present invention has a preview function for previewing motion images displayed on the setting display screen. According to the present invention, the preview function can be used to preview the motion displayed on the setting display screen for visual confirmation, which helps to confirm whether there are setting errors, etc.

[0021] (2) The injection molding machine of the present invention has the motion setting device of the present invention described above.

[0022] The effects of the invention

[0023] According to the present invention, an action setting device and an injection molding machine are provided that eliminate the complexity of setting up the ejector action in an injection molding machine and the associated complicated screen, thereby making it easier to set up the ejector action in the injection molding machine.

[0039] The motion setting device and injection molding machine related to the present invention will be described with reference to the accompanying drawings. Furthermore, the present invention is not limited to the following embodiments, but includes various modifications and applications within its scope.

[0040] As shown in the figures, the motion setting device 1 of the present invention is a device for setting the motion of the ejector 40, which includes a setting display screen 2 in the form of a touch panel. This structure performs the following steps: First, by touching any point within the graph 9 displayed on the setting display screen 2, the motion sequence and position of the ejector 40 are input; second, based on the input motion position, motion parameters including the motion speed, motion position, motion time, and motion mode of the ejector 40 are input; and third, the input motion position and motion parameters are displayed in the graph 9 on the setting display screen 2 and displayed numerically in the numerical display unit 7. Furthermore, by performing the first to third steps in the motion sequence, the motion position and motion parameters of each motion are displayed in the graph 9 and displayed numerically in the numerical display unit 7.

[0041] The motion setting device 1 displays the motion position and motion parameters of each motion on the graph 9 of the setting display screen 2 and displays the values ​​on the numerical display unit 7. Therefore, the motion image of the ejector 40 can be easily formed through the graph 9, and the motion parameters can also be numerically confirmed. The setting display screen 2 is a touch panel that can display the required information and perform simple input operations, so the motion input of the ejector 40 can be easily performed. In particular, settings can be made by directly touching the graph 9 of the setting display screen 2, so visual settings are possible.

[0042] The following is an explanation of each component.

[0043] Injection molding machine

[0044] Injection molding machine 10 Figure 1 As shown in the overall diagram, the machine 11 includes at least an injection unit 12, a mold clamping unit 13, and a display unit 14. A cover 20, a safety door 29, and a cover 30 are respectively provided at the drive positions of the injection unit 12 and the mold clamping unit 13. Furthermore, in... Figure 1 In this example, the control device 51 is located inside the machine tool 11.

[0045] <Ejector>

[0046] like Figure 2 As shown, the ejector 40 is disposed within the mold closing device 13. The mold closing device 13 includes a mold 21 consisting of a fixed mold 21a and a movable mold 21b, and is a device for performing mold closing, mold opening, high-pressure mold closing, etc. Plastic injected from the top nozzle of the heating cylinder 17 provided in the injection device 12 is filled into the mold 21. The plastic filled in the mold 21 cools and solidifies to form a molded product. Regarding the molded product, after the mold 21 is opened, the ejector 40 ejects (removes) the molded product from the mold 21 by the action of the ejector 40.

[0047] In addition, such as Figure 2 As shown, the mold clamping device 13, equipped with an ejector 40, moves the movable mold 21b mounted on the movable platen forward and backward to perform mold closing, mold opening, and high-pressure mold clamping. The moving mold 21b is moved forward and backward using a conventionally known method that utilizes a mold clamping drive unit 25 and extends or bends the toggle lever 23 via a lead screw (not shown) and a crosshead 24. Furthermore, four connecting rods 22 support the movable platen on which the movable mold 21b is mounted to guide its forward and backward movement.

[0048] In this mold-closing device 13, the molded article remains adhered to the movable mold 21b after demolding. When the molded article is removed from the movable mold 21b, the ejector 40 is activated to demold the molded article from the mold 21b. Figure 2 As shown, the ejector 40 is operated by causing the ejector rod 42, which is provided on the ejector base 41, to protrude into the movable mold 21b to be opened. While the ejector 40 operates by causing the ejector rod 42 to protrude, it is sometimes difficult to remove the molded part with a single protrusion action; in most cases, the ejector rod 42 protrudes multiple times. Conventionally, multiple operating modes are set to operate the ejector 40 in this way to reliably remove the molded part. Since the operation of the ejector 40 is complex, its settings are cumbersome, and this complexity needs to be improved, which is insufficient. This invention solves this problem.

[0049] [Motion Setting Device]

[0050] The action setting device 1 is used to set the action of the ejector 40. The action setting device 1 is a device with a setting display screen 2 in the form of a touch panel for setting the action of the ejector 40, and performs the following steps.

[0051] <Setting the display screen>

[0052] The setting display screen 2 is a display screen in which all or part of the screen has a touch panel. At least the chart 9, which is input via touch operation, uses a touch panel. Either any other part can also be a touch panel, or the entire screen can be a touch panel. The left side of the setting display screen 2 has a group of setting item buttons 6. Regarding the setting item button group 6, any setting item buttons can be configured as needed. The setting items and their configuration are not particularly limited, and it can also include a setting item display for displaying setting items. Figure 3 The example of setting item button group 6, arranged from top to bottom, includes an ejector selection button, a mode selection button, an edit mode button, an overall repeat display, and an automatic interval display. Furthermore, while "button" can refer to a press-type button, here it refers to a button that can be input via touch operation on the touch panel.

[0053] In detail, Figure 3 In the setting display screen 2 shown in the example, among the setting item button group 6 on the left, the "Ejector" button is used to select "On" - "Off" for the ejector. The "Mode" button is the button to switch the operation mode of the ejector 40; "Any" means that the operation mode can be set arbitrarily on Figure 9. The "Edit Mode" button is the selection button when inputting the operation mode on Figure 9. The "Overall Repeat" display shows the number of times the ejector 40's operation is repeated, and the "Automatic Interval Arrangement" display shows the automatic interval arrangement.

[0054] exist Figure 3 In the example, Graph 9 is displayed in the left half of the setting display screen 2. The vertical axis of Graph 9 represents the ejection process, and the horizontal axis represents the ejection stroke. A scroll bar is displayed on the right side of Graph 9. A meter bar indicating the current position of the ejector is displayed in the lower left of the setting display screen 2. The "Ejector Position" is displayed numerically to the right of the meter bar. The upper right half of the setting display screen 2 displays the setting bars for the "Forward Pressure" and "Reverse Pressure" of the ejector 40. These forward and reverse pressures refer to the forward and reverse pressures of the ejector in all processes. A numerical display unit 7 is arranged in the right half of the setting display screen 2. This numerical display unit 7 displays the "Speed ​​(%)", "Position (mm)", and "Time (s)" for each movement of the ejector 40. A "Preview" button 3 is displayed in the lower right of the setting display screen 2. This button is used to preview a 2D or 3D image or motion image of the ejector settings.

[0055] Chart 9 in Figure 3 In the example shown, the left half of the setting display screen 2 displays the set action position and action parameters in a chart mode. Here, "action parameters" refers to the action items of the ejector 40, which can include the forward, backward, protrusion (forward) stroke length, backward stroke length, temporary stop time, vibration (shaking) time, etc. of the ejector rod 42. In this invention, such action parameters can be set by touch input to the chart 9. Moreover, by inputting the action mode in the chart 9, a numerical display unit 7 that is linked to the chart is also displayed on the right side of the setting display screen 2, so the overall action mode can be visually confirmed and the setting value can be confirmed on the numerical display unit 7.

[0056] also, Figure 15 The example shown is different from the setting display screen 2 in this invention. It is a display screen that arranges setting items and setting values ​​sequentially. This display screen does not display the operation of the ejector 40 in a chart mode, but instead displays the operation of the ejector 40 as a display screen of setting values.

[0057] <Step 1 to Step 3>

[0058] The first step is to touch any point on the graph 9 displayed on the setting display screen 2 to input the operation sequence and position of the ejector 40. The second step is to input operation parameters including the speed, position, time, and operation mode of the ejector 40 based on the input operation position. The third step is to display the input operation position and operation parameters on the graph 9 in the setting display screen 2 and display the values ​​on the numerical display unit 7. Setting display screen 2 is as follows... Figures 4 to 12 As shown, the motion position and motion parameters of each motion to be set are displayed in Figure 9 and the values ​​are displayed in the numerical display section 7. Next, we will proceed with the following... Figures 4 to 12 Please provide an explanation.

[0059] exist Figure 3 In the initial state shown, the editing mode is "off", therefore, as Figure 4 Switch to "On" as shown in (A). In this case, the touch input strip 9a is displayed on "Step 1" in Figure 9. This touch input strip 9a is preferably a strip-shaped area, and in fact, it is more preferable to display, for example, a blue colored strip.

[0060] For example, if you touch the location with a 90mm protrusion in the touch input band 9a, then as Figure 4 As shown in (B), the new process 1 is displayed as a line starting from the origin. Simultaneously, the numerical display section 7 on the right displays the action sequence, action display, action speed, and action position, showing No. "1", action "ejection", speed (%), and position (mm) "90". Entering "10" in the speed display field displays "10" in the speed (%) field. Entering the speed displays "10%" at the point of 90mm of the protruding stroke in Figure 9. When process 1 is set, touch the input strip 9a as shown... Figure 4 Move to step 2 as shown in (B).

[0061] Figure 5 (A) is the case where touch input was performed in the touch input strip 9a shown in process 2. At the touched location, such as... Figure 5 When the operation is in the same position as in step 1, as shown in (A), the operation is temporarily stopped, and the numerical display unit 7 displays No. "2" and the operation is "paused". As the operation time, by inputting the time (s) as "1" in the numerical display unit 7, a time of "1s" is displayed at the point where the protruding stroke of step 2 in Figure 9 is 90mm. When step 2 is set, the touch input band 9a moves to step 3.

[0062] Figure 5 Example (B) illustrates a case where the protruding stroke of process 1 is changed after process 2 has been set. The touch input band 9a is located at the position of process 3, therefore only process 3 input can be performed on the touch input band 9a. However, by changing the operation position bar of process 1 on the numerical display unit 7 to "90" to "110", the location of process 1 in Figure 9 is moved to a position of 110mm. This allows the operation parameters of the set process to be changed on the numerical display unit 7, and this change is displayed in conjunction with the operation mode in Figure 9.

[0063] exist Figure 5 In (B), process 1 is modified and the modified chart 9 is displayed. However, since process 2 is temporarily stopped (paused), the operation mode of chart 9 differs from the operation display of the numerical display unit 7. In the event of such a difference, as... Figure 5 As shown in (B), an adjustment line 9b (actually, for example, a red line) is drawn to represent the action based on the value in the numerical display unit 7. Furthermore, when the adjustment line 9b is displayed, the editing mode cannot be set to "off". When the adjustment line 9b appears, there is a conflict between Figure 9 and the numerical display unit 7 in the preceding and following processes, therefore the position of process 1 is returned to its original 90mm, or by... Figure 6 The method is to change the position of process 2.

[0064] Figure 6 (A) refers to the case where the marked position of the set process 2 is touched. Upon this touch, the color of the marked process 2 changes to the change operation mark 9c. By changing it in this way, process 2, as the target, is in a set change state. Furthermore, in the state of being marked as change operation mark 9c, "Move," "Add," "Change," and "Delete" are displayed at the bottom edge of the graph, showing four options for changing the action position (reset in graph 9), changing the action parameters (reset in numerical display unit 7), adding actions, and deleting actions.

[0065] Figure 6 (B) is the case where the "Move" button is activated by touching it. This allows the position of the marker for process 2, the target process, to be reset on Figure 9. At this time, the blue touch input band 9a becomes inactive, and the yellow change input band 9d is displayed. The position of the marker can be changed by touching any point on the change input band 9d. The changed input result is reflected in conjunction with the numerical display unit 7.

[0066] Figure 7 (A) is to Figure 6In the change operation in (B), the position of marker 9c is changed to the same position as the protruding stroke of process 1. By changing it to the same position, the difference in the operation mode of chart 9 and the operation display of the numerical display unit 7 between process 1 and process 2 is eliminated, and therefore the adjustment line 9b disappears. This change can be made by touching the protruding stroke 110mm on the change input band 9d. While the "Move" button is active, operations other than position changes are not allowed. After the position change operation is completed, pressing the "Move" button again will... Figure 7 The position is determined as shown in (B), and the touch input band 9a is displayed again in step 3, which is the next step, so that other operations can be performed. Figure 15 Compared to conventional input operations on the settings screen, this touch input operation has the following advantages: a) the position can be changed simply by touching the screen (without needing to press number keys as before); b) the position can be changed regardless of the type of action.

[0067] Figure 8 (A) refers to the case where the marker for step 2 is touched to set marker 9c in the change operation. When marker 9c in the change operation is displayed, four operation buttons are displayed at the bottom edge, and the "Add" button is touched. In this case, step 3 with the same action parameters as step 2 is added as the next step after the selected step 2. Furthermore, if other markers already exist in step 3, the new marker becomes step 3 and the existing step 3 becomes step 4, and subsequent markers are also shifted one step to the right. The step added using "Add" is, for example, added as a temporary stop action with an initial value of 1 second at the same position as the original marker.

[0068] Figure 8 (B) is also with Figure 8 (A) is also the case where the mark in step 2 is set as mark 9c in the change operation, but in this Figure 8 In (B), the "Change" button was touched. This allows modification of the action marked 9c in the Change operation. Each time "Change" is touched, the modified action cycles in the following order: "Push Out" → "Pause" → "Shake" → "Push Out". Figure 8 In example (B), the change operation of process 2 is marked with "jitter" and the following action mode is shown: after protruding to a position of 110mm protrusion stroke at a speed of 10% in process 1, it vibrates at the same position for 1 second in process 2, and stops temporarily for 1 second without vibration in process 3.

[0069] Figure 9Example (A) shows how to change process 3 from "pause" (temporarily stopped) to "protrusion" (raised). First, touch the marker for process 3 to set it as marker 9c in the change operation, and then touch the "move" button to display the change input band 9d in process 3. Next, touch other positions within the change input band 9d to set new positions. Figure 9 In example (A), step 3 is changed from a position where the stroke protrusion is 110mm to a position where the stroke protrusion is 0mm. In this state, the operation mode of graph 9 in step 3 differs from the operation display of the numerical display unit 7, so an adjustment line 9b is generated based on the markings of step 2. To eliminate this adjustment line 9b, the "Move" button is touched to set it to "Off," and then the "Change" button is touched twice to change from the "Pause" state to the "Eject" state, thereby aligning the operation mode of step 3 with that of the numerical display unit 7. Thus, as Figure 9 As shown in (B), the adjustment line 9b can be eliminated, and the numerical display unit 7 displays "ejection", speed 0% and position 0mm, consistent with Figure 9.

[0070] Figure 10 (A) is deleted Figure 9 A diagram illustrating the action pattern of process 2 in (B). Figure 9 In state (B), touch the mark of process 2 to set it as mark 9c in the change operation. If you touch "delete" in this state, the selected process 2 will be deleted, the process will move forward 1 step, and process 3 will become process 2.

[0071] Figure 10 (B) shows the number of operations that can be displayed in Chart 9 when the edit mode is "On". The number of operations that can be displayed can be changed through settings, but in this example, a maximum of 5 operations can be displayed. When the edit mode is "Off", all operations that have been set can be enlarged / reduced to fit the size of Chart 9. Figure 10 In example (B), 30 processes are set when the editing mode is "on," but the chart on the setting display screen 2 shows 5 processes, from process 26 to process 30. By operating the scroll bar, the numerical display unit 7 and the chart 9 are scrolled together. In the numerical display unit 7, the action parameter group corresponding to the mark shown in the chart 9 can be displayed in a way that is surrounded by a black frame.

[0072] Figure 11 (A) is in relation to Figure 10 The chart when the editing mode is "off" under the same settings as (B). When the editing mode is "off", all processes are displayed in the chart. Therefore, it is displayed when the process spacing is narrow. On the other hand, the numerical display unit 7 displays at the normal display size. Figure 11Example (A) shows eight processes, from process 23 to process 30. Furthermore, operating the scroll bar will scroll through the processes in the numerical display section 7, but the display of chart 9 will not change.

[0073] Figure 11 (B) is an explanatory diagram of the copy and paste functions of the process. Regarding copy and paste, when multiple markers are selected, the "Copy" and "Paste" buttons are displayed in Figure 9. In this state, if the "Copy" button is touched, the information of the selected multiple markers is stored in the internal memory. By selecting a specific marker again and then touching the "Paste" button, the group of markers stored in the internal memory can be inserted at the next process position of the selected markers. Figure 11 In example (B), select the two markers for process 1 and process 2 as marker 9c in the change operation, touch the displayed "Copy" button, touch marker 9c in the change operation of process 2, and then touch the "Paste" button. This will allow you to... Figure 12 As shown in (A), processes 1 and 2 are pasted as processes 3 and 4. The operation parameters of the additional processes 3 and 4 are also displayed in the numerical display unit 7.

[0074] about Figure 12 (B) is the correct choice. Figure 11 (B) shows two markers for process 1 and process 2. In the change operation, mark 9c. Touch the displayed "Copy" button, then touch marker 9c in the change operation for process 1, and then touch the "Paste" button. Thus... Figure 12 As shown in (B), add steps 1 and 2 after step 1 and designate them as steps 2 and 3. Step 2 before pasting is changed to step 4. Using this operation, it is possible to set... Figure 12 The action pattern shown in (B) is as follows.

[0075] As another setting method, for example, in all the processes set, for example Figure 4 (B) Figure 5 (B) Figures 6 to 11 As shown, an easily observable orange vertical line (solid line) is displayed at the position of the process with the largest operating position. This display indicates the maximum forward position of the ejector. Thus, when the ejector 40 is moved to its maximum forward position, it is preferable to display the maximum forward position as the "maximum forward limit 9e" as a colored solid line in Figure 9 to prevent exceeding the maximum forward limit 9e setting.

[0076] When all settings are completed and the edit mode is set to "Off", if the final process does not reach the backtrack limit, it is preferable to display a warning message such as "The mold cannot be closed because the final process did not reach the backtrack limit. Please repeat the settings to reach the backtrack limit." The edit mode cannot be set to "Off" if the backtrack limit is not reached. Additionally, when "Overall Repeat" is set to a value of 1 or higher, all set processes are repeated as one loop.

[0077] By setting the "ejector" to "on" or "off," it can be set to be used or not used. The operation position and operation parameters are displayed in graph 9 of the setting display screen 2, and the operation position and operation parameters are also displayed numerically in the numerical display unit 7. Therefore, it is possible to easily form an image of all or part of the operation of the ejector 40 through graph 9, and to easily confirm the values ​​through the numerical display unit 7. The setting display screen 2 is a touch panel that can display the required information and is easy to operate, so it is easy to input the operation of the ejector 40. In particular, it is possible to perform direct touch operation on graph 9 of the setting display screen 2, so that the settings can be performed visually.

[0078] The settings display screen 2 has the function of displaying settings tools such as "Move," "Add," "Change," "Delete," "Copy," and "Paste" as described above. The operator can access these tools as needed, allowing for easy addition of new processes, modification of existing processes, change of target positions for existing processes, and deletion of existing processes simply by touching icon 9. Furthermore, the settings display screen 2 has a scroll bar, allowing for virtually unlimited addition of settings, accommodating various operation modes.

[0079] (Touch position calibration)

[0080] The motion setting device 1 includes: a correction function that corrects for locations mistakenly entered due to touch operation; and a setting device for fine-tuning the input correction position and motion parameters. As a result, it is possible to change the motion position within a narrow range, which is a drawback of touch operation. Fine-tuning of the motion position and motion parameters can be performed using the setting device, which allows direct input of numerical values. When the "Automatic Alignment Interval" shown in Figure 9 is set to a value of 1 or higher, the touched point can be corrected to a multiple of the automatic alignment interval. For example, when the automatic alignment interval is set to 30mm, touching any position between 15mm and 44mm on Figure 9 results in an input of 30mm, touching any position between 45mm and 74mm on Figure 9 results in an input of 60mm, and touching any position between 75mm and 105mm on Figure 9 results in an input of 90mm. When the automatic alignment interval is 0, no correction is performed, and the input is rounded to one decimal place, which is the input limit for the injection molding machine.

[0081] (Preview)

[0082] like Figure 13 As shown in (A) and (B), the desired action setting device 1 has a preview function that allows for previewing all or part of the action of the ejector 40. A preview display screen 4 for performing this preview can be displayed by touching the preview button 3. By previewing the action of the ejector 40, the action displayed on the setting display screen 2 can be visually confirmed, making it easy to check for setting errors, etc. By touching... Figure 3 The preview button 3 in the lower right corner of the settings display screen 2 shown in (A) is used to... Figure 13 The preview display screen 4 is displayed as shown in (B). This still image can be either a two-dimensional or a three-dimensional image. The displayed preview display screen 4 has a playback button 5. By touching the playback button 5, the action of the ejector 40 can be reproduced using a moving image. When the playback button 5 is touched again, the moving image can be reproduced again.

[0083] To more easily confirm the reproduced action, it is desirable to set the reproduction speed of any action to 100%, and to slow down the reproduction speed of other actions relative to this 100% reproduction speed. Thus, by setting the reproduction speed of the fastest action to 100%, the reproduction speed of other actions becomes slower and easier to view, thereby facilitating action confirmation. Here, "100%" refers to the upper limit of the reproduction speed that the eye can follow during reproduction. By setting the fastest action among the actions of the object, or even if not the fastest but one of the faster main actions, to 100%, other actions can be made slower.

[0084] During playback, it is preferable to display the gauge bar 8 in the preview display screen 4. This allows the position of the action to be confirmed via the displayed gauge bar 8. The width of the gauge bar 8 can be changed within the screen. It is preferable that the gauge bar 8 is displayed on the same screen as the preview display screen 4, thereby facilitating easy confirmation of the action's position.

[0085] (Control device)

[0086] Figure 14 This is a schematic system diagram of the control device 51 that controls the motion setting device 1. The control device 51 is not limited to any structure capable of controlling the motion setting device 1. Figure 14 For example, the control device 51 mainly consists of a CPU 121, a chipset 123, and an internal memory 125. The chipset 123 is connected to the CPU 121 via an internal bus 122. A bus 124, using a local area bus such as a PCI bus, is connected to the chipset 123 to form an HMI (Human Machine Interface) control system. The internal memory 125, including various types of memory such as RAM and ROM, is connected to the bus 124. Furthermore, the display device 100 is connected to the bus 124 via a display interface (IF) 126, and a driver 128 for reading and writing to an external memory 129 composed of storage media such as a memory card is connected to the bus 124 via an input / output interface (IF) 127. In this case, the display device 100 has a display Fd with a touch panel Ft.

[0087] Chipset 123 is connected to bus 131, the same bus as bus 124, to form a PLC (Programmable Logic Controller) control system. Input / output interface (IF) 133 and input / output interface (IF) 135 are connected to bus 131. IF 133 is used to send switching data Di from switches, etc., to CPU 121 and to send control command data Do from CPU 121 to the corresponding actuator. IF 135 is used to send the detection signals Si from various sensors after analog-to-digital conversion to CPU 121, and to send the control signal So obtained by digital-to-analog conversion of the control command data from CPU 121 to the corresponding actuator. Thus, a defined feedback control system and open-loop control system are formed.

[0088] The internal memory 125 stores the PLC program and the HMI program, as well as various processing programs. Furthermore, the PLC program is software used to implement the sequential actions and monitoring of various functions in the ejector device, while the HMI program is software used to set and display the action parameters of the ejector 40, and to display the monitoring data of the ejector's actions.

[0089] Using such a control device 51, the motion setting device 1 of the present invention can be controlled to display the preview display screen 4. According to the motion setting device 1, by reproducing the various actions under various settings of the ejector action in the preview display screen 4, the action can be simulated before the ejector 40 is actually operated, and damage to the mold caused by incorrect setting of the ejector action can be prevented.

[0090] The control device 51, equipped with a touch panel-style setting display screen 2, displays a graph 9 showing the relationship between the action sequence and position of the ejector 40. By touching any point on the graph 9, the action position can be set. The actions and positions of the ejector 40 can be set based on the input information, the graph 9 is generated, and all ejection processes are displayed on the numerical display unit 7. By performing this operation the required number of times, the actions of the ejector 40, consisting of various action modes, can be set. Furthermore, the action parameters displayed in the graph 9 can be managed as molding conditions.
