It is a figure which shows the 3rd example of a display of the setting screen of embodiment. It is a figure which shows the example of a setting of track record value relevant information.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1A is a schematic diagram of an injection molding machine 1 to which the present invention is applied, and FIG. 1B is a schematic diagram of a control panel 2 used in the injection molding machine 1. The injection molding machine 1 includes a mold opening / closing device 8 that holds a mold, an injection device 9 that injects a molding material into the mold, a control unit 5 that controls the operation of the injection molding machine 1, and a control panel 2. The injection device 9 includes, for example, a hopper 9a that supplies a resin material, a cylinder 9b, and a nozzle 9c. A screw (not shown) rotates in the cylinder and advances to push the resin material to the nozzle 9c.

  The control unit 5 is configured around a microcomputer, and includes a CPU 6, a storage unit 7, a ROM, a RAM, a timer, a counter, and the like (not shown). The control unit 5 controls the operation and state of each component of the injection molding machine 1, acquires various measurement values from the injection molding machine 1, and stores them in the storage unit 7. A control panel 2 is connected to the control unit 5.

  In FIG. 1B, the control panel 2 includes a display unit 3 and an operation unit 4. An operator can perform an input operation and setting / changing of setting conditions via the operation unit 4. As will be described later, the display unit 3 displays set information, actual values used for quality determination of injection molding, and the like.

  FIG. 2 shows a first display example of the setting screen 11 of the display unit 3. The setting screen 11 includes an item display area 11A indicating a currently displayed target item, a result value display area 11B, a setting condition display area 11C, and a display item selection area 11D. In FIG. 3, the plasticize button 14 is selected.

  In the case of the screw-type injection device 9 (see FIG. 1), plasticization means a process of making a molding material flexible by heating with a heater and rotation of the screw. The plasticizing conditions vary depending on the product to be molded and the molding material, but it is necessary to maintain appropriate conditions to maintain the quality. Therefore, the names and values of various performance values related to plasticization are shown in the performance value display area 11B.

  In the present embodiment, by selecting each actual value displayed in the actual value display area 11B, related information of the actual value is displayed in the empty area of the item display area 11A. In the display example of FIG. 2, “filling peak pressure” is selected from the actual value display area 11B, and the ID number “P300” assigned to “filling peak pressure” is displayed in the help column 13 of the item display area 11A. .

  When the operator wants to capture the actual value of “filling peak pressure” into a personal computer or the like, the operator can obtain the ID number on the same setting screen 11 only by selecting the subarea 12 of “filling peak pressure”.

  In the case of a touch panel, the selection of the actual value on the setting screen 11 may be performed by touching the corresponding actual value subarea 12, for example, the “filling peak pressure” subarea 12 with a finger. Alternatively, a desired actual value sub-area 12 may be selected using the multifunction key of the operation unit 4 in FIG. 1B, or may be clicked using a mouse. In this example, the actual value of “filling peak pressure” is selected. However, for other actual values such as screw position and injection pressure, the help field 13 can be obtained by simply touching or selecting the sub-area 12 of the actual value. The ID number of the actual value can be displayed immediately.

  In the first display example, the actual value display area 11B corresponds to the first display area for displaying the actual value, and the help column 13 for displaying the ID number of the actual value is the second display area for displaying the related information. Correspond.

  FIG. 3 shows a setting screen 21 which is a second display example of the display unit 3. The setting screen 21 includes an item display area 21A indicating a currently displayed target item, an actual value display area 21B, a setting condition display area 21C, and a display item selection area 21D. Also in FIG. 3, the plasticizing button 14 is selected.

  When “filling peak pressure” is selected as the actual value from the actual value display area 21B, the ID value “P300” of “filling peak pressure” is displayed in the help field 23 of the item display area 21A, and the average value of the filling peak pressure and The maximum value is displayed. The average value and the maximum value in this case are, for example, the average value and the maximum value from the start of production in the injection molding machine 1 to the point in time when the actual value information is displayed.

  By using the help function of the item display area 21A, a certain amount of information can be displayed as related information. The operator can set what information is displayed in the help field 23 in relation to the actual value. For example, desired information can be set as related information from the logging data indicating the past history of the actual value.

  FIG. 4 shows an example of the logging data 41 of the actual value. The logging data 41 is stored as a record value data file in the storage unit 7 of FIG. When it is desired to confirm the entire logging data 41 as independent information, it can be displayed by, for example, touching or clicking the quality control button in the item selection area 21D.

  When a part of the logging data 41 is used as the related information of the actual value (for example, “filling peak pressure”), a desired information item is selected in advance. For example, when the actual value statistical data 42 is set as related information, statistical data such as an average value, a range, a maximum value, a minimum value, and a standard deviation are displayed in a predetermined column (an example is a help column 23) in FIG. Is done. Of course, it is not necessary to display all of these, and only necessary parameters may be set. With this configuration, when it is desired to check related data of a specific actual value during monitoring of the injection molding machine 1, it can be immediately displayed on the same screen by simply touching or clicking the sub-area 12 of the actual value.

  In the second display example, the actual value display area 21B corresponds to a first display area for displaying actual values, and a predetermined column for displaying statistical data corresponds to a second display area for displaying related information.

  FIG. 5 shows a setting screen 31 which is a third display example of the display unit 3. The setting screen 31 includes an item display area 31A indicating a currently displayed target item, an actual value display area 31B, a setting condition display area 31C, and a display item selection area 31D. In the example of FIG. 5, the temperature button 16 is selected. In addition to the help column 33, a setting condition display area 31C is also used as the related information display area.

  In order to manage the temperature at the time of melting of the resin material, temperature sensors are arranged at a plurality of locations of the cylinder 9b and the nozzle 9c of the injection device 9 (see FIG. 1A), and temperature information is collected from each sensor. In the actual value display area 31B, the main set value which is a preset value and the actual value measured by the sensor are displayed for each zone.

  In this case, when the operator selects the zone 3 of the actual value display area 31B, the ID number “H303” of “zone 3 temperature” as the actual value is displayed in the help column 33 of the item display area 31. Furthermore, a graphic image indicating the arrangement position of the temperature sensor in the zone 3 and information related to the sensor are displayed in the setting condition display area 31C.

  The selection of zone 3 in the actual value display area 31B is performed by touching the sub area (temperature display area) 35 of the zone 3 as in the first display example (FIG. 2) and the second display example (FIG. 3). , Can be selected by clicking. By selecting the actual value, necessary related information is displayed on the same setting screen 31. The operator can confirm the information he wants to know directly without moving to another screen.

  In the third display example, the actual value display area 31B corresponds to the first display area for displaying the actual value, and the help column 33 and the setting condition display area 31C correspond to the second display area for displaying the related information. .

  FIG. 6 shows an example of related information associated with the actual value. For example, an ID number, a statistical value, a related condition, and the like are set in association with “filling peak pressure”. Further, an average value, a maximum value, a minimum value, a standard deviation, and the like can be set as statistical values. As related conditions, the filling speed and temperature can be set. These are merely examples, and the present invention is not limited to these.

  For each of the actual values such as the screw position and the injection pressure in FIG. 2, the same setting screen can be obtained simply by selecting a specific actual value or the subarea 12 for displaying it by setting desired related information in advance. You can immediately check the information you want to know above.

  When an arbitrary actual value is selected on the display unit 3 of the control panel 2, it is the function of the CPU 6 that reads related information of the actual value from the storage device 7 and displays it on the same setting screen. A computer program that causes the CPU 6 to perform such an operation is stored in a ROM or an IC card (not shown).

  In the embodiment, the help fields 13, 23, and 33 of the setting screens 11, 21, and 31 are used as the related information display area, or the setting condition display area 31C is used as the related information display area. However, the present invention is not limited to these examples. For example, if it is simple related information such as ID information and average value assigned to the actual value, it may be configured to pop up on the setting screen. Also in this case, it is possible to obtain an effect that information desired to be known can be immediately confirmed on the same screen by selecting a desired result value. The ID number of the actual value, the statistical data, and the related condition are examples of information related to the actual value, and may not be displayed, or may be displayed by arbitrarily combining these related information. .
