The state of the injection molding machine 100 when performing is shown.

  The operation state display unit 11 outputs the control signal (a signal for sliding the cores 50a and 50b toward the cavity space CV) to the core tractor 5 (first core tractor). The same control signal is received from the molding control unit 10, and as shown in FIG. 4, the symbol SY1 representing the sliding motion toward the cavity space CV of the cores 50a and 50b is displayed, and the core tractor 5 moves toward the cavity space CV. To show the operator that the user is sliding.

  In addition, since the 2nd core tractor does not exist in a present Example, the operation state display part 11 does not display the symbol which shows the present state of a 2nd core tractor.

  The operation state display unit 11 displays symbols SY2, SY3, and SY4 indicating the current states of the mold clamping device 2, the injection / plasticizing device 3, and the ejector device 4, and the mold clamping device 2 opens the mold. To the operator that the injection / plasticizing device 3 is in an inoperative state and the ejector device 4 is in a state after the ejector pin 40 is returned (non-projecting state). .

  In addition, the operation state display unit 11 displays symbols SY5 and SY6 representing the current states of the cavity ventilator and the air ejector, and indicates that the cavity ventilator and the air ejector that exist in two each are in an inoperative state. Present to the operator.

  FIG. 5 is a diagram for explaining the details of the symbols SY1 to SY6 on the operation state display screen. FIGS. 5A to 5D are the details of the symbol SY1, and FIGS. H) shows details of symbols SY2 and SY4, FIGS. 5 (I) to 5 (K) show details of symbol SY3, and FIGS. 5 (L) to 5 (O) show details of symbols SY5 and SY6, respectively.

  5A shows a state in which the cores 50a and 50b are slid toward the cavity space CV by the core tractor 5, and FIG. 5B shows that the cores 50a and 50b are moved to the cavity space CV by the core tractor 5. The state which the core tractor 5 has stopped after sliding toward is represented. 5C shows a state in which the cores 50a and 50b slide away from the cavity space CV by the core tractor 5, and FIG. 5D shows the cores 50a and 50b by the core tractor 5. This represents a state where the core tractor 5 is stopped after sliding away from the space CV.

  FIG. 5E shows a state where the mold opening is performed by the mold clamping device 2, and FIG. 5F shows a state where the mold clamping device 2 is stopped after the mold opening is performed by the mold clamping device 2. Represents the state. 5 (G) shows a state where the mold is closed by the mold clamping device 2, and FIG. 5 (H) shows a state where the mold clamping device 2 is closed after the mold is closed by the mold clamping device 2. Indicates the stopped state. The same applies to the symbol SY4 representing the state of the ejector device 4.

Represents a state.

  Thus, the operation state display unit 11 presents the operation state of the injection molding machine 100 to the operator while displaying these symbols SY1 to SY6.

  In addition, the operation state display unit 11 displays “mold open limit”, “mold fully closed”, “ejector return”, “nozzle touch”, “pause”, “cooling” at the top of the operation state display screen shown in FIG. ”,“ Delay ”,“ Holding pressure ”,“ Filling ”,“ Weighing ”, and“ Weighing complete ”are arranged, and the respective statuses are indicated by turning on or off the indicators. (In FIG. 4, the ejector pins 40 are returned to the non-projecting state by turning on the indicators corresponding to the “ejector return” and “nozzle touch”, respectively, and the nozzle touch is in a state of being performed. Is shown.)

  Further, as described above, the control device 1 causes the same control signal to be output to the operation state display unit 11 at the same time as the molding control unit 10 outputs a control signal to each of the various components. Thus, while the injection molding machine 100 is actually operated, its operation state is displayed on the display device 6 (hereinafter, this method is referred to as “normal mode”), but the molding control unit 10 controls various components. By outputting the control signal to the operation state display unit 11 while prohibiting the output of the signal, it is as if the injection molding machine 100 is operating without actually operating the injection molding machine 100. The operation state may be displayed on the display device 6 (hereinafter, this method is referred to as “simulation mode”). Note that the molding control unit 10 originally receives signals (for example, a signal indicating the position of the plasticizing screw 31 and the like) from various components (if the injection molding machine 100 is operating). The output timing of the control signal for various components is determined. In the simulation mode, the control signal is automatically output to the operation state display unit 11 at a predetermined output timing.

  Further, the control device 1 performs the same control at the same time when the molding control unit 10 outputs a control signal to each of the various components except the core tractor 5 under the condition that the resin pellets are not supplied to the injection cylinder 30. By outputting a signal (including a control signal to be output to the core tractor 5) to the operation state display unit 11, various components other than the core tractor 5 can be provided without using resin. These operating states may be displayed on the display device 6 while actually operating (hereinafter, this method is referred to as “dry mode”). Note that the molding control unit 10 is originally in a dry mode, as in the simulation mode, when a certain condition is originally satisfied (for example, when the position of the plasticizing screw 31 reaches a predetermined position). )) Forcibly output to the operation state display unit 11 at a predetermined output timing.

  The control device 1 may cause the operator to select any one of the normal mode, the simulation mode, and the dry mode by displaying a mode selection screen (not shown). The simulation mode may be automatically executed after the operation timing of the movable part is set.

  The operation timing setting unit 12 is a functional element for setting the operation timing of the movable part arranged in relation to the mold structure, and the movable part arranged in relation to the mold structure is, for example, Includes core tractor, gate cutter, cavity ventilator, air ejector, etc.

  Specifically, the operation timing setting unit 12 displays a screen for setting the operation timing of the core tractor 5 (hereinafter referred to as “operation timing setting screen”) on the display device 6 and operates the operation timing. Let the person set it.

  FIG. 6 is a diagram illustrating an example of the operation timing setting screen. The operation timing setting screen includes “priority core”, “control selection”, “mode”, “time”, “manual mode”, “delay”, “ “Mold open position” and “Mold closed position” are set items.

  “Priority core” is a setting item for preferentially selecting a core tractor to be controlled. “Return” (meaning movement of the core tractor away from the cavity space) and “On” (core tractor It means the movement to project into the cavity space.)

  “Control selection” is a setting item for selecting a control method for stopping the core tractor 5, and has options of “position limit” and “time”, and when “position limit” is selected. Causes the core tractor 5 to stop when the cores 50a, 50b reach a predetermined position (for example, when the position sensor detects that the cores 50a, 50b have reached a predetermined position), and the "time" When selected, the core tractor 5 is stopped when the set time elapses after the core tractor 5 is operated regardless of whether the cores 50a and 50b have reached the predetermined positions. .

  “Mode” is a setting item set individually for “core return” and “core on”. For “core return”, “off”, “before mold opening”, “mould open”, “After mold opening is completed” and “mold opening is temporarily stopped” options are available. For “with core”, “off”, “before mold closing”, “during mold closing”, “after mold clamping is completed” ”And“ Mold Closed Pause ”.

  When “OFF” is selected for “Core return”, the operation of the core tractor 5 is prohibited. When “Before mold opening” is selected, before the mold opening is started. Will be activated. Further, when “mould open” is selected for “return to core”, the core tractor 5 operates during mold opening. When “after mold opening is completed” is selected, mold opening is performed. When the mold opening is temporarily stopped, the operation is performed when the mold opening is temporarily stopped.

  In addition, when “off” is selected for “core on”, the operation of the core tractor 5 is prohibited. When “before mold closing” is selected, before the mold closing starts. Will work. Further, when “mold closing” is selected for “core insertion”, the core tractor 5 operates during mold closing. When “after mold clamping is completed” is selected, mold closing is performed. When the mold closing is temporarily stopped, the operation is performed when the mold closing is temporarily stopped.

  “Time” is a setting item that is valid when “Time” is set for “Control selection”, and is set individually for “Core return” and “Core input”. The time from when 5 is activated to when it is stopped can be set in units of 0.1 second.

  “Manual mode” has choices of “individual” and “interlocking”, and when “individual” is selected, the core tractor 5 responds to an input by the operator during the period selected in “mode”. When “interlocking” is selected, it automatically operates during the period selected in “mode”.

  “Delay” is a setting item for finely adjusting the operation timing of the core tractor 5 so that the operation timing can be finely adjusted in units of 0.1 seconds.

  “Mold open position” and “Mold closed position” are set to “Mode” when “Mold open”, “Mold open pause”, “Mold closed”, or “Mold closed pause” is set. This is an effective setting item, and the timing for operating the core tractor 5 when the mold is opened or closed can be finely adjusted in units of 0.1 mm based on the position of the movable mold 21.

  By setting the setting items described above, the operator can determine the operation timing of the core tractor 5, but if an inappropriate setting is made, the injection molding machine 100 may form a defective molded product, or In some cases, the mold, the ejector pin 40, or the cores 50a and 50b may be damaged.

  7 and 8 are diagrams for explaining an example of a failure caused by an inappropriate operation timing of the core tractor 5. FIG.

  Specifically, in FIG. 7, when the molten resin RS is injected from the injection / plasticizing apparatus 3 into the cavity space CV, the cores 50a and 50b are still placed in predetermined positions (positions indicated by broken lines in the figure). This shows the situation when the injection molding machine 100 forms a defective molded product.

  Further, FIG. 8 shows that when the molded product MP is pushed out from the movable mold 21, the cores 50a and 50b are not yet returned to the predetermined positions (positions indicated by the broken lines in the figure), so A situation in which the injection molding machine 100 damages the ejector pins 40 and the cores 50a and 50b by projecting 40 toward the molded product MP (see arrow AR7) is shown.

  In order to prevent the occurrence of such a problem, the operator sets the operation timing of the core tractor 5 by the operation timing setting unit 12 and then operates the injection molding machine 100 in the simulation mode or the dry mode.

  The operation timing information output unit 13 notifies the operation timing of the movable unit set by the operation timing setting unit 12 according to the actual or virtual operation state of the injection molding machine 100 displayed by the operation state display unit 11. It is a functional element for outputting information.

  Specifically, the operation timing information output unit 13 is an injection molding machine regardless of whether or not the core tractor 5 is actually operated (that is, in any of the normal mode, the simulation mode, and the dry mode). When the operation timing of the core tractor 5 set by the operation timing setting unit 12 arrives while the actual or virtual operation of 100 changes (for example, the core tractor 5 output by the molding control unit 10 operates). When the control signal for receiving the signal is received), the symbol SY1 on the operation state display screen shown in FIG. 4 is changed to a state corresponding to the operation.

  Further, the operation timing information output unit 13 outputs a control signal to the audio output device 7 when the operation timing of the core tractor 5 arrives, and outputs a short notification sound, or the operation continuation time of the core tractor 5 For example, the notification sound is continuously output.

  Further, the operation timing information output unit 13 outputs a control signal to the light emitting device 8 when the operation timing of the core tractor 5 arrives, and causes the light emitting device 8 to emit light for a short period of time. The light emitting device 8 is caused to emit light continuously over a continuous time.

  The operation timing information output unit 13 may output a control signal to either the audio output device 7 or the light emitting device 8.

  In this way, the operation timing information output unit 13 can inform the operator of the operation timing of the core tractor 5, particularly when the injection molding machine 100 is virtually operating in the simulation mode, or When the injection molding machine 100 is partially operating in the dry mode, the operation timing of the core tractor 5 set by the operation timing setting unit 12 can be notified to the operator, and is the operation timing appropriate? The operator can determine whether or not the core tractor 5 is actually operated.

  The operation timing suitability determination unit 14 determines whether the operation timing of the movable part set by the operation timing setting unit 12 is appropriate based on the actual or virtual operation state of the injection molding machine 100. For example, the actual or virtual operation state of the injection molding machine 100 in the simulation mode or the dry mode (for example, the actual or virtual position of the fixed mold 20 or the plasticizing screw 31). )), It is determined whether or not a situation as shown in FIG. 7 or FIG. 8 (a situation that causes a problem due to improper arrangement of the cores 50a and 50b) occurs. When it is determined that a situation has occurred, it is determined that the operation timing of the core tractor 5 is inappropriate.

  When it is determined that the operation timing of the core tractor 5 is inappropriate, the operation timing suitability determination unit 14 outputs a control signal to the display device 6 to indicate that the operation timing of the core tractor 5 is inappropriate. A text message is displayed on the display device 6 so as to inform the operator.

  With the above-described configuration, the injection molding machine 100 does not actually operate the core tractor 5 and the actual or virtual operation of the injection molding machine 100 changes or the operation timing of the core tractor 5 arrives or Since the operating period of the core tractor 5 can be informed to the operator, the core tractor 5 can be operated in a state in which the mold, the core tractor 5 and various components related to the core tractor 5 are not damaged. The operator can determine whether or not the operation timing is appropriate.

  In addition, the injection molding machine 100 uses the simulation mode, and the operation timing of the core tractor 5 is changed while the virtual operation of the injection molding machine 100 changes without actually operating the injection molding machine 100. Since the operator can be notified of the arrival or the operation period of the core tractor 5, there is no possibility of damaging the mold, the core tractor 5, and various components related to the core tractor 5, and a defective molded product. The operator can determine whether or not the operation timing of the core tractor 5 is appropriate.

  Moreover, the injection molding machine 100 operates the injection molding machine 100 without operating the core tractor 5 or supplying resin by using the dry mode, and the actual operation of the injection molding machine 100 can be performed. Since the operator can be notified of the arrival of the operation timing of the core tractor 5 or the operation period of the core tractor 5 during the transition, the mold, the core tractor 5 and various components related to the core tractor 5 can be used. There is no possibility of damaging, no possibility of forming a defective molded product, and the operation timing of the core tractor 5 is operated while operating the injection molding machine 100 in a state closer to the actual operation compared to the simulation mode. The operator can determine whether it is appropriate.

  Further, the injection molding machine 100 automatically determines whether the operation timing of the core tractor 5 set by the operation timing setting unit 12 is appropriate based on the actual or virtual operation state of the injection molding machine 100. Therefore, it is possible to assist the operator in determining whether or not the operation timing is appropriate.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, the operation state display unit 11 displays the transition of the actual or virtual operation of the injection molding machine 100 on the display device 6 with the same elapsed time as the actual elapsed time. Transitions may be displayed in slow motion (time passage slower than actual time passage) or quick motion (time passage faster than real time passage), fast forward, rewind, random access, reverse playback, frame The transition of the operation may be displayed while enabling forward playback, reverse playback of frame advance, pause, and the like.

  Further, in the above-described embodiment, the injection molding machine 100 does not actually operate the core tractor 5, and the actual or virtual operation of the injection molding machine 100 changes, and the core tractor 5 The operator is notified of the arrival of the operation timing or the operation period of the core tractor 5, but the actual operation of the injection molding machine 100 is performed without actually operating other movable parts such as a gate cutter, a cavity ventilator, and an air ejector. Alternatively, during the transition of the virtual operation, the operator may be notified of the arrival of the operation timing of the movable unit or the operation period of the movable unit.
