Description

Technical Field

[0001] This invention relates to a molding machine. Background Technology

[0002] JP2016-159481A discloses examples of conventional injection molding machines. The injection molding machine operates according to molding conditions to form a molded article. These molding conditions include set values ​​for parameters (speed, pressure, temperature, time, travel distance, etc.) related to the driving of each drive unit of the injection molding machine. The injection molding machine has a screen for setting these set values ​​(setting screen). Summary of the Invention

[0003] For example, when changing a mold to a new one in an injection molding machine, the operator uses the machine to perform a condition setting operation. During this operation, trial molding samples are produced while adjusting the settings until a product meeting the required specifications is formed. The molding conditions obtained from this operation are then used to create the final product.

[0004] During condition setting operations, operators use the setting screen displayed on the display device and input setting values. Sometimes, operators may want to refer to past setting values ​​when setting new values. In this case, operators can use the overview of changes related to multiple items included in the molding conditions (setting history screen) displayed on the display device to view past setting values. Figure 9 , Figure 10 Examples of the settings screen Gs and settings history screen Gr are shown below. Figure 10 The description of the Gs settings screen has been omitted.

[0005] However, the larger configuration history screens (Gr) are displayed overlaid on the configuration screen (Gs). Therefore, after viewing past settings on the configuration history screen (Gr), the operator needs to delete the configuration history screen (Gr) and return to the configuration screen (Gs) to input the settings. Furthermore, in the configuration history screen (Gr), change information related to multiple items included in the molding conditions is displayed side-by-side, requiring the operator to locate the change information related to the item being set. Therefore, the condition setting operation is complex.

[0006] The present invention aims to provide a molding machine that allows easy viewing of change information related to items included in the molding conditions.

[0007] To achieve the above objectives, the molding machine according to the present invention is characterized by comprising: a memory device that stores change information related to a plurality of items included in the molding conditions; a display device that displays a setting screen for setting a setting value in at least one of the plurality of items; an input device that inputs an item selection operation for selecting an item from the items displayed on the setting screen on the display device; and a control device that overlays a change information screen on the setting screen and displays it on the display device, wherein the change information screen displays only the change information related to the item selected by the item selection operation.

[0008] According to the present invention, if an item is selected as the setting object in the setting screen, then among the multiple items included in the molding conditions, only the change information screen displaying the change information related to the selected item is overlaid on the setting screen. Therefore, when setting a setting value for an item included in the molding conditions, the change information related to that item can be easily viewed. Attached Figure Description

[0037] Hereinafter, regarding an injection molding machine according to an embodiment of the present invention, reference will be made to... Figures 1-10 The injection molding machine plasticizes the resin material and injects it into the mold cavity to form the molded product.

[0038] like Figure 1As shown, the injection molding machine 1 according to this embodiment has a molding machine body 10 including a mold clamping device 2, an injection device 3, and an extraction device 4. The molding machine body 10 is mounted on a machine base 5. In addition, the injection molding machine 1 has a control unit 7 for controlling the molding machine body 10.

[0039] The mold closing device 2 opens and closes the fixed side mold 81 and the movable side mold 82, and closes the mold. The fixed side mold 81 and the movable side mold 82 form the mold cavity 83.

[0040] The mold closing device 2 includes a fixed template 21, a movable template 22, and a mold closing drive mechanism 23. A fixed side mold 81 is mounted on the fixed template 21. A movable side mold 82 is mounted on the movable template 22. The mold closing drive mechanism 23 includes, for example, an electric motor, a ball screw mechanism, and a toggle mechanism. The mold closing drive mechanism 23, through the fixed template 21 and the movable template 22, causes the fixed side mold 81 and the movable side mold 82 to move in the front-to-back direction (…). Figure 1 It is tightened in the left and right directions and generates clamping force.

[0041] The injection device 3 includes a cylinder 31, a nozzle 32, a resin supply section 33, a heater 34, a screw 35, and a screw drive mechanism 36.

[0042] The cylinder body 31 has a cylindrical shape. The cylinder body 31 is arranged in a front-to-back direction. A nozzle 32 is located at the front end of the cylinder body 31. A resin supply section 33 is located at the rear end of the cylinder body 31. The resin supply section 33 has a hopper for containing powdered or granular resin, which is the material to be molded. The resin supply section 33 supplies resin to the cylinder body 31. The heater 34 is, for example, a belt heater located on the outer circumference of the cylinder body 31. The screw 35 is rotatably and movable back-to-back within the cylinder body 31. The screw drive mechanism 36 has, for example, an electric motor and a ball screw mechanism. The screw drive mechanism 36 rotates and moves the screw 35 back-to-back.

[0043] The removal device 4 has an ejector pin (not shown) and a protrusion mechanism 41. The protrusion mechanism 41 has, for example, a cylinder. The protrusion mechanism 41 drives the ejector pin to remove the molded article from the movable side mold 82.

[0044] Control unit 7 controls the overall movement of injection molding machine 1. For example... Figure 2 As shown, the control unit 7 includes a display device 71, an input device 72, a storage device 73, and a control device 78.

[0045] The display device 71 is, for example, a flat panel display such as a liquid crystal display.

[0046] The input device 72 is, for example, an operation key or a touch panel. The operation key is, for example, a key on a hardware keyboard. The touch panel is overlapped on the display surface of the display device 71, and the button images or toggle switch images displayed on the display surface combine to form software keys. The positions (tap images, etc.) corresponding to the button images or toggle switch images on the touch panel are equivalent to operating the software keys, that is, inputting an operation to the input device 72.

[0047] Storage device 73 is, for example, a disk drive or a non-volatile memory.

[0048] The storage device 73 stores the molding conditions. The molding conditions include the settings (speed, pressure, temperature, time, travel distance, etc.) set in the items involved in driving the clamping device 2, injection device 3, and ejection device 4 of the injection molding machine 1.

[0049] Storage device 73 stores an identification information table Ti. Identification information table Ti contains an identification information set Ks, which includes identification information and related information for identifying multiple items included in the molding conditions. Figure 3 An example of an identification information table Ti containing multiple identification information sets Ks is shown.

[0050] The identification information set Ks includes identification information K1, name K2, unit K3, and input screen type K4. Identification information K1 is used to identify multiple items and various control information items included in the molding conditions used in the control device 78. Identification information K1 is set with a unique number (identification number) assigned to each item. Name K2 is set with the name of the item identified by the identification number set in identification information K1. Unit K3 is set with the unit of the item's set value. Input screen type K4 is set with the type of input screen used to input the item's set value. If the item has no unit, the unit K3 field is blank. Input screen type K4 is set with options such as "numeric keys," "toggle switch," or "selection list."

[0051] Storage device 73 stores a change information table Th. Change information table Th contains a set of change information Js related to multiple items included in the molding conditions. Figure 4 The example shown is a change information table Th containing multiple change information sets Js.

[0052] The change information set Js includes number J1, identification information J2, setting value before change J3, setting value after change J4, change time J5, and username J6. Identification information J2, setting value before change J3, setting value after change J4, change time J5, and username J6 are all change information J.

[0053] Number J1 indicates the order in which change information sets Js are added to change information table Th. Identification information J2 indicates the identification number of the item involved in change information set Js. Setting value before change J3 indicates the setting value before the change. Setting value after change J4 indicates the setting value after the change (new setting value). Change time J5 indicates the date and time of the change. Username J6 indicates the login username in change time J5. Change information set Js may include the number of injections in change time J5. The number of injections is the number of molding actions performed in injection molding machine 1 within a specified period. The number of injections is reset, for example, when the mold is changed to a new mold in injection molding machine 1, or when molding of a molded product begins.

[0054] The control device 78 includes a computer. The control device 78 is communicatively connected to a display device 71, an input device 72, and a storage device 73.

[0055] The control device 78 displays various information on the display device 71 and performs actions based on the operations input into the input device 72. It should be noted that the display device 71 and the input device 72 may be, for example, a tablet or laptop computer that is wirelessly connected via the control device 78.

[0056] The control device 78 is communicatively connected to the mold closing drive mechanism 23, the heater 34, the screw drive mechanism 36, and the protrusion mechanism 41. Based on the molding conditions stored in the storage device 73, the control device 78 controls the mold closing drive mechanism 23, the heater 34, the screw drive mechanism 36, and the protrusion mechanism 41, etc., to perform molding actions simultaneously with the molding machine body 10.

[0057] If a new setting value is set for an item included in the molding conditions (i.e., the setting value is changed), the control device 78 generates a set of change information Js related to that item and adds it to the beginning of the change information table Th. Figure 4 (The very top). Figure 4 In the change information table Th shown, change times J5 are arranged in a retrospective manner, with change information sets Js arranged from top to bottom. Change information table Th can contain, for example, 10,000 change information sets J. If a new setting value is set in an item included in the molding conditions when change information table Th is completely filled, the control device 78 overwrites the new change information set Js on the oldest change information set Js.

[0058] The control unit 7 has multiple setting screens for setting items included in the molding conditions. If an operator inputs a specified setting screen display operation into the input device 72, the control device 78 displays the setting screen corresponding to that setting screen display operation on the display device 71. Figure 9The image shows an example of a settings screen Gs used to set settings for items involved in injection and plasticizing. The settings screen Gs displays the current settings for the items involved in injection and plasticizing. Each item displayed in the settings screen Gs is accompanied by its own identification number.

[0059] If a setting screen Gs is displayed on the display device 71, and the operator inputs an operation (item selection operation) to the input device 72 to select one item from the multiple items displayed on the setting screen Gs, the control device 78 will overlay the input screen for inputting setting values ​​and the item setting history screen on the setting screen Gs. The setting value is set in the item selected through the item selection operation (selected item X).

[0060] Specifically, if an input item selection operation is performed, the control device 78 obtains the identification number of the selected item X, and specifically includes an identification information set Ks containing identification information K1 with the identification number of the selected item X set in the identification information table Ti. Furthermore, the control device 78 obtains the name K2 of the specific identification information set Ks as the name of the selected item X, obtains the unit K3 as the unit of the selected item X, and displays an input screen according to the input screen type K4. Simultaneously, the control device 78 displays an item setting history screen that arranges and displays the change information J related to the selected item X on this input screen.

[0061] Next, refer to the instructions in the input screen and project settings history screen. Figures 5-9 .exist Figures 5-8 In the text, a portion of the description of the settings screen Gs has been omitted.

[0062] The settings screen Gs has an area (item Ia) that displays settings such as "Injection speed switching position". Figure 9 ). Item Ia comes with an identification number (“325”). Furthermore, if the operation of tap item Ia (item selection operation) is input to input device 72, control device 78 obtains the identification number accompanying item Ia as the identification number for selected item X. Based on the identification number, control device 78 obtains “injection five-speed switching position” from identification information table Ti as the name of selected item X, obtains “mm” as the unit of selected item X, and obtains “numeric keys” as the type of input screen. Moreover, as Figure 5 As shown, the control device 78 overlays the input screen G11 and the project setting history screen G21 on the setting screen Gs and displays them on the display device 71. The input screen G11 is of the "numeric keypad" type.

[0063] The input screen G11 has a question section G11a, a display section G11b, a slider section G11c, a numeric keypad section G11d, a reset button G11e, an OK button G11f, and a delete button G11g.

[0064] The control device 78 displays the name of the selected item X in the question section G11a. When displaying the input screen G11, the control device 78 reads the current setting value of the selected item X from the storage device 73 and displays it on the display section G11b.

[0065] The slider unit G11c has a slider TB. When the input screen G11 is displayed, the control device 78 moves the slider TB to the position corresponding to the current setting value of the selected item X. If the operation of sliding the slider TB to the left is input to the input device 72, the control device 78 decreases the value of the display unit G11b; if the operation of sliding the slider TB to the right is input to the input device 72, the control device 78 increases the value of the display unit G11b.

[0066] The numeric keypad G11d includes numeric keys ("0" to "9", ".") and symbol keys ("*", " / ", "+", "-", "+ / -"), which function the same as those in a typical electronic calculator. When an operation of a tapped numeric keypad is input to the input device 72, the control device 78 displays the corresponding numerical value on the display unit G11b. When an operation of a tapped symbol key is input to the input device 72, the control device 78 performs mathematical calculations involving the operation symbols corresponding to the symbol keys.

[0067] If the tap reset button G11e is input to the input device 72 after the operation of the slider section G11c or the numeric key section G11d, the control device 78 will return the value of the display section G11b to the current setting value of the selected item X (the previous setting value of the display input screen G11), and the slider TB will return to the position corresponding to the current setting value of the selected item X.

[0068] If the operation of the tap confirmation button G11f is input to the input device 72, the control device 78: (i) if the value on the display unit G11b is in operation, calculates the result and displays it on the display unit G11b (equivalent to the "=" button in an electronic calculator); (ii) if the value on the display unit G11b is not in operation, saves the value as a setting value in the storage device 73 and deletes the input screen G11. The control device 78 also deletes the input screen G11 when the operation of the tap deletion button G11g is input to the input device 72.

[0069] The project history screen G21 has a title section G21a, a change information name section G21b, a change information display section G21c, and a show / not show button G21d.

[0070] The control device 78 displays "Setting History" in the title section G21a and displays "No.", "Date and Time", "Old", "New", and "Unit" in the change information name section G21b in order from left to right.

[0071] The control device 78 displays the change information J related to the selected item X on the change information display unit G21c. Specifically, the control device 78 extracts a change information set Js from the change information table Th, which includes identification information J2 that sets an identification number for the selected item X. The control device 78 displays a display information set Ls on the change information display unit G21c, which arranges the change time J5, the setting value before the change J3, and the setting value after the change J4 of the extracted change information set Js in a left-to-right order. Figure 5 For ease of explanation, the information set Ls is enclosed in an ellipse with a single dotted line, but the ellipse is not actually displayed. In the change information display unit G21c, the change time J5, the setting value before change J3, and the setting value after change J4 are set to correspond to the "date and time," "old," and "new" in the change information name unit G21b. Furthermore, the control device 78 arranges and displays each information set Ls in descending order, starting from the new change time J5. The change information display unit G21c is equivalent to a change information screen that only displays change information J related to the selected item X among the multiple items included in the molding conditions. It should be noted that "only displaying change information J related to the selected item X among the multiple items included in the molding conditions" means that change information J related to items other than the selected item X among the multiple items included in the molding conditions is not displayed; only the change information J related to the selected item X is displayed as change information J.

[0072] The control device 78 adds numbers in ascending order starting from the new change time J5 to the left side of each display information set Ls and displays them. The unit of the selected item X is displayed to the right side of each display information set Ls. In the change information display unit G21c, this number is set to correspond to the "No." in the change information name unit G21b, and the unit of the selected item X is set to correspond to the "Unit" in the change information name unit G21b.

[0073] It should be noted that if the operation (change information selection operation) of the display information set Ls displayed on the tap change information display unit G21c is input to the input device, the display information set Ls of the tap is selected, and the control device 78 can be configured to: display the previous setting value J3 contained in the display information set Ls (i.e., as a candidate setting value for the selected item X) on the display unit G11b, or set the previous setting value J3 contained in the display information set Ls as the setting value for the selected item X (and save it in the storage device 73). Thus, the operator can set the previous setting value as the selected item X through a relatively simple operation.

[0074] The show / hide button G21d is located in the title section G21a. The show / hide button G21d is a toggle switch that toggles the display / hide function of the change information name section G21b and the change information display section G21c. When the change information name section G21b and the change information display section G21c are displayed, the control device 78 displays an upward-pointing triangle image as the show / hide button G21d. Figure 5 If the operation of the upward-pointing triangle image (non-display operation) is input to the input device 72, the control device 78 deletes the change information name section G21b and the change information display section G21c, and displays the downward-pointing triangle image as the display / non-display button G21d. Figure 6 If the operation of the downward-pointing triangle image (screen display operation) is input to the input device 72, the control device 78 displays the change information name section G21b and the change information display section G21c, and displays the upward-pointing triangle image as the display / non-display button G21d.

[0075] If the control device 78 deletes the input screen G11, it will also delete the item setting history screen G21 at the same time.

[0076] It should be noted that when the operation of dragging and dropping the title section G11a of the input screen G11 (screen movement operation) is input to the input device 72, the control device 78 can be configured, based on this operation, to move only the input screen G11 on the setting screen Gs, or to move both the input screen G11 and the item setting history screen G21. Furthermore, for example, when the operation of dragging and dropping the title section G21a of the item setting history screen G21 (screen movement operation) is input to the input device 72, the control device 78 can be configured, based on this operation, to move only the item setting history screen G21 on the setting screen Gs, or to move both the input screen G11 and the item setting history screen G21. Thus, the operator can move the input screen G11 or the item setting history screen G21 and visually confirm the area of ​​the hidden setting screen Gs within these screens.

[0077] The setting screen Gs has, for example, a toggle switch image for inputting the setting value of "SRC-III" (Item Ib). Figure 9 ). Item Ib comes with an identification number (“580”). Furthermore, if the operation of tap item Ib (item selection operation) is input to input device 72, control device 78 obtains the identification number attached to item Ib as the identification number for selected item X. Based on the identification number, control device 78 obtains “SRC-III” from identification information table Ti as the name of selected item X, and obtains “toggle switch” as the type of input screen. Moreover, as Figure 7 As shown, the control device 78 overlays the input screen G12 and the project setting history screen G22 on the setting screen Gs and displays them on the display device 71. The input screen G12 is of the "toggle switch" type.

[0078] When the control device 78 displays the input screen G12 on the display device 71, each time the operation of tap item Ib is input to the input device 72, the toggle switch image related to item Ib is alternately switched to the ON state image. Figure 7 ) and the image of the OFF state ( Figure 9 ).

[0079] The input screen G12 has a reset button G12e and an OK button G12f.

[0080] If the operation of the tap reset button G12e is input to the input device 72, the control device 78 sets the toggle switch image related to item Ib to the state before displaying the input screen G12.

[0081] If the operation of the tap confirmation button G12f is input to the input device 72, the control device 78 will save the set value according to the state (ON state, OFF state) of the toggle switch image in the storage device 73 and delete the input screen G12. It should be noted that when the control device 78 displays the input screen G12, it can delete the input screen G12 by inputting the operation of any position of the tap setting screen Gs to the input device.

[0082] The project setting history screen G22 includes a title section G22a, a change information name section G22b, a change information display section G22c, and a show / display button G22d. Except for the fact that the change information name section G22b and the change information display section G22c do not display information related to the unit selected for item X, the project setting history screen G22 is identical to the project setting history screen G21 (including substantial similarity), therefore a detailed description of the project setting history screen G22 is omitted.

[0083] The settings screen Gs has an area (item Ic) that displays settings such as "VP switching mode" (VP switching mode). Figure 9 ). Item Ic comes with an identification number (“102”). Furthermore, if the operation of tap item Ic (item selection operation) is input to input device 72, control device 78 obtains the identification number attached to item Ic as the identification number for selected item X. Based on the identification number, control device 78 obtains “VP switching mode” from identification information table Ti as the name of selected item X, and obtains “selection list” as the type of input screen. Moreover, as Figure 8 As shown, the control device 78 overlays the input screen G13 and the item setting history screen G23 on the setting screen Gs and displays them on the display device 71. The input screen G13 is of the "selection list" type.

[0084] The input screen G13 has a question section G13a, a selection list section G13d, an OK button G13f, and a delete button G13g.

[0085] The control device 78 displays the name of the selected item X in the title section G13a. The control device 78 displays multiple selection buttons G13d1 to G13d5 in the selection list section G13d. The multiple selection buttons G13d1 to G13d5 correspond to set values ​​that can be set to the selected item X. In the input screen G13, the multiple selection buttons G13d1 to G13d5 correspond to "stroke switching," "pressure," "timer," "mold internal pressure," and "calculation (pressure switching)." When displaying the input screen G13, the control device 78 reads the current set value of the selected item X from the storage device 73 and highlights the setting button corresponding to the current set value among the multiple selection buttons G13d1 to G13d5. Furthermore, if the operation of one of the multiple selection buttons G13d1 to G13d5 is input to the input device 72, the control device 78 highlights the selected selection button based on that operation.

[0086] If the operation of the tap confirmation button G13f is input to the input device 72, the control device 78 saves the setting value corresponding to the highlighted selection button in the storage device 73 and deletes the input screen G13. The control device 78 also deletes the input screen G13 when the operation of the tap deletion button G13g is input to the input device 72.

[0087] The project setting history screen G23 includes a title section G23a, a change information name section G23b, a change information display section G23c, and a show / display button G23d. Except for the fact that the change information name section G23b and the change information display section G23c do not display information related to the unit selected for item X, the project setting history screen G23 is identical to the project setting history screen G21 (including substantial similarity), therefore a detailed description of the project setting history screen G23 is omitted.

[0088] As described above, the injection molding machine 1 includes a molding machine body 10 for molding into a molded article and a control unit 7. The control unit 7 includes: a memory device 73 that stores change information J related to multiple items included in the molding conditions; a display device 71 that displays a setting screen Gs for setting values ​​for items included in the molding conditions; an input device 72 that inputs an item selection operation from the items displayed on the setting screen Gs on the display device 71; and a control device 78 that overlays an item setting history screen G21 on the setting screen Gs and displays it on the display device 71. The item setting history screen G21 includes a change information display section G21c that displays only the change information J related to the item selected through the item selection operation (selected item X). Thus, when setting values ​​for items included in the molding conditions, the operator can easily view the change information J related to that item.

[0089] Furthermore, the control device 78 overlays the input screen G11, used for inputting setting values ​​for selected item X, and the item setting history screen G21 on the setting screen Gs and displays them on the display device 71. Thus, the operator can input setting values ​​while viewing past setting values ​​displayed in the item setting history screen G21.

[0090] Furthermore, when the input screen G11 and the item setting history screen G21 are displayed on the display device 71, if the operation of the display / non-display button G21d of the tap item setting history screen G21 (screen non-display operation) is input to the input device 72, the control device 78 continues to display the input screen G11 and sets the change information display section G21c of the item setting history screen G21 to non-display. When the input screen G11 is displayed on the display device 71 and the change information display section G21c of the item setting history screen G21 is not displayed on the display device 71, if the operation of the display / non-display button G21d of the tap is input to the input device 72 (screen display operation), the control device 78 displays the change information display section G21c on the display device 71. Thus, the operator can reduce the size of the item setting history screen G21 as needed, expanding the possible visual confirmation area of ​​the setting screen Gs.

[0091] Furthermore, the change information J stored in storage device 73 includes identification information J2 of the item involved in the change information J, the previous setting value J3 as the setting value before the change, the new setting value J4 as the setting value after the change, and the change time J5 as the time when the new setting value was set in that item. The change information J displayed in the change information display unit G21c of the item setting history screen G21 is the previous setting value J3, the new setting value J4, and the change time J5. The change information J displayed in the change information display unit G21c may include at least the previous setting value J3. Thus, the operator can view past setting values ​​set before the current setting value.

[0092] Furthermore, in the change information display section G21c of the project setting history screen G21, multiple change information Js are displayed in order of change time J5. This allows for the confirmation of past settings for the selected project X in chronological order.

[0093] This specification describes an injection molding machine according to one embodiment of the present invention, but the present invention is not limited to injection molding machines. The present invention can be applied to other types of molding machines such as die casting machines.
