  Embodiments according to the present invention will be described below with reference to the drawings. This embodiment does not limit the present invention.

(First embodiment)
FIG. 1 is a block diagram illustrating a configuration example of an injection molding machine 1 according to the first embodiment. The industrial machine 1 may be, for example, a machine tool, a die casting machine, an extrusion molding machine or the like in addition to an injection molding machine.

  An injection molding machine 1 as an industrial machine includes a frame 2, a fixed plate 3, a moving plate 4, a tie bar 5, a mold clamping drive mechanism 6, an injection device 7, a control unit 8, an extrusion mechanism 9, And a human machine interface 60.

  The frame 2 is a base of the injection molding machine 1. The fixed platen 3 is fixed on the frame 2. A fixed mold 11 is attached to the fixed platen 3. One end of the tie bar 5 is fixed to the fixed platen 3 and the other end is fixed to the support platen 10. The tie bar 5 extends from the fixed plate 3 to the support plate 10 through the moving plate 4.

  The moving board 4 is placed on a linear guide (not shown) provided on the frame 2. The movable platen 4 is guided by a tie bar 5 or a linear guide, and can move toward or away from the fixed platen 3. A moving mold 12 is attached to the moving plate 4. The moving mold 12 faces the fixed mold 11, approaches the fixed mold 11 together with the moving board 4, and is combined with the fixed mold 11. When the moving mold 12 and the fixed mold 11 are combined and closed, a space corresponding to the product shape is formed between the moving mold 12 and the fixed mold 11.

  The mold clamping drive mechanism 6 includes a toggle mechanism 13 and a toggle mechanism drive unit 14. The toggle mechanism drive unit 14 includes a mold clamping servomotor 21, a ball screw 22, and a transmission mechanism 23 in order to drive the toggle mechanism 13. A cross head 15 is attached to the tip of the ball screw 22. As the ball screw 22 rotates, the crosshead 15 moves toward or away from the moving board 4. The transmission mechanism 23 transmits the rotation of the mold clamping servomotor 21 to the ball screw 22 and moves the crosshead 15.

  When the toggle mechanism driving unit 14 moves the cross head 15, the toggle mechanism 13 is activated. For example, when the cross head 15 moves toward the movable platen 4, the movable platen 4 moves toward the fixed platen 3 and the mold is closed. On the contrary, when the cross head 15 moves in a direction away from the movable platen 4, the movable platen 4 moves in a direction away from the fixed platen 3, and mold opening is performed.

  The extrusion mechanism 9 includes an extrusion servo motor 71, a ball screw 72, and a transmission mechanism 73 in order to remove the molded product from the moving mold 12. The tip of the ball screw 72 penetrates the inner surface of the moving mold 12. As the ball screw 72 rotates, the ball screw 72 pushes out the product adhered to the inner surface of the moving mold 12. The transmission mechanism 73 transmits the rotation of the extrusion servomotor 71 to the ball screw 72, and moves the ball screw 72 in the left-right direction in FIG.

  The injection device 7 includes a heating barrel (band heater) 41, a screw 42, a measuring unit 43, and an injection device drive unit 44. The heating barrel 41 includes a nozzle 41 a that injects a molten material into a mold and is connected to a hopper 45. The screw 42 is provided so as to be movable inside the heating barrel 41.

  The weighing unit 43 includes a weighing servo motor 46 and a transmission mechanism 47 that transmits the rotation of the weighing servo motor 46 to the screw 42. When the weighing servo motor 46 is driven and the screw 42 is rotated in the heating barrel 41, the resin of the molding material is introduced into the heating barrel 41 from the hopper 45. The introduced resin is sent to the front end side of the heating barrel 41 while being heated and kneaded. The resin is melted and stored in the tip portion of the heating barrel 41. The molding material is not limited to a resin, and any material can be used as long as it can be used as a molding material such as metal, glass, rubber, and a carbonized compound containing carbon fiber.

  The injection device drive unit 44 includes an injection servo motor 51, a ball screw 52, and a transmission mechanism 53. As the ball screw 52 rotates, the screw 42 moves in the left-right direction in FIG. The transmission mechanism 53 transmits the rotation of the injection servo motor 51 to the ball screw 52. Thereby, when the injection servo motor 51 is rotated, the screw 42 is moved. The molding material is injected from the nozzle 41a by the screw 42 pushing out the molding material stored in the tip portion of the heating barrel 41 from the nozzle 41a.

  The human machine interface (HMI / F) 60 displays various information regarding the injection molding machine 1. The HMI / F 60 may include, for example, a display unit and a keyboard, or may be a touch panel display. The operator can input settings such as a command related to the operation of the injection molding machine 1 through the HMI / F 60. Further, the user can display image data of a maintenance portion requiring maintenance or a maintenance manual through the HMI / F 60. The maintenance part is a part that constitutes the injection molding machine 1, and is a part that changes due to wear, deformation, material adhesion, and the like. Therefore, the maintenance part requires maintenance such as periodic replacement, cleaning, and repair. The image data is actual photograph data of the maintenance part imaged by a camera or the like, and the data format may be arbitrary.

  The controller 8 monitors sensor information received from various sensors (not shown) during the injection process, and controls the injection device 7 so that a numerical value obtained from the sensor information does not exceed a preset threshold value. In addition, the control unit 8 displays necessary data on the display unit in response to a user instruction through the HMI / F 60.

  FIG. 2 is a diagram illustrating an example of the configuration of the control unit 8. The control unit 8 includes an information processing unit 61, a setting unit 62, a storage unit 63, an injection device control unit 64, and an input / output unit 65.

  The arithmetic processing unit 61 controls the mold clamping force, the temperature of the heating barrel 41, and the injection pressure while comparing the detection values obtained from the various sensors with the setting values stored in the setting unit 62. The arithmetic processing unit 61 also controls each component of the control unit 8.

  The setting unit 62 stores information input via the HMI / F 60. For example, the setting unit 62 stores information related to the setting value of the maximum injection pressure, the setting value of the mold clamping force, the setting of the operation mode, and the like input from the operator.

  The storage unit 63 stores information such as a program for operating the injection molding machine 1, the set value, and detection values obtained from various sensors. The storage unit 63 stores information related to maintenance. For example, the storage unit 63 stores a maintenance manual and image data of the maintenance part. The storage unit 63 stores the image data classified for each maintenance part of the industrial machine 1. Further, the storage unit 63 stores the date and time when image data was captured or the date and time when image data was captured from the input / output unit 65. These image data are displayed on the display unit of the HMI / F 60 and are referred to when the user performs maintenance. The display of the image data will be described later with reference to FIGS. 3 (A) and 3 (B).

  The injection device control unit 64 controls driving of the injection servo motor 51. The injection device control unit 64 controls the injection pressure of the injection device 7 by controlling the driving of the injection servomotor 51, for example.

  The input / output unit 65 is configured to take information from the outside into the control unit 8 or to output information from the control unit 8 to the outside. The input / output unit 65 can be communicably connected to other terminals by wire or wirelessly. The communication connection between the input / output unit 65 and another terminal is not particularly limited, and may be, for example, USB, wireless LAN (Local Area Network), wired LAN, Bluetooth (registered trademark), or the like. Thereby, the input / output unit 65 can capture the actual image data of the maintenance part of the injection molding machine 1 from the outside. For example, the image data is obtained by the user capturing an image of the maintenance portion using the camera function of the camera or the terminal. The user transmits this image data from the camera or terminal to the injection molding machine 1. The input / output unit 65 receives the image data of the maintenance part transmitted from the user terminal or the like and stores it in the storage unit 63.

  More specifically, the user periodically takes an actual image of each maintenance part with a camera or a terminal, and transmits the image data to the injection molding machine 1. At this time, the camera or the terminal may transmit the imaging date and time of the image data together with the image data. When receiving the image data, the control unit 8 stores the image capturing date / time or the receiving date / time in association with the image data in the storage unit 63. At this time, the user selects a maintenance part corresponding to the image data on the display unit of the HMI / F 60. The control unit 8 classifies the image data into the maintenance portion selected by the user. Thereby, the memory | storage part 63 can preserve | save the log | history of image data about each of the some maintenance part of the injection molding machine 1. FIG. The selection of the maintenance part and the classification of the image data will be described later in “Fetching image data”.

  As described above, since the storage unit 63 stores the change of each maintenance part as image data, even if each maintenance part of the injection molding machine 1 is gradually deteriorated by use, the user can change the maintenance part as shown in FIG. As shown, a change in the maintenance portion can be easily grasped by referring to the history of the image data. As a result, the user can determine the repair time or replacement time of the maintenance part relatively easily. In addition, the period when a user images a maintenance part is not specifically limited. Therefore, for example, the period at which the user images the maintenance part may differ depending on the maintenance part, or may be determined by the usage time of the injection molding machine 1. Preferably, the period for imaging the maintenance portion is defined by the maintenance manual.

  3A and 3B are diagrams showing a maintenance screen of the display unit 100 of the HMI / F 60. FIG. The display unit 100 displays an operation process of the injection molding machine 1, sensor information received from various sensors, and the like. In addition, the display unit 100 displays necessary data in response to a user instruction. For example, at the time of maintenance, the display unit 100 receives a user instruction and displays a maintenance screen shown in FIG.

  On the maintenance screen, first, the display unit 100 displays a diagram or a photograph of the entire injection molding machine 1 as shown in FIG. In the screen of FIG. 3 (A), the user's comment 103, the current date and time 105 (year, month, day, time), the manual display button 107, etc. are displayed in addition to the figure or photograph 101 of the entire injection molding machine 1. Yes.

  Next, when the user selects a certain maintenance part of the injection molding machine 1 shown on the display unit 100, the display unit 100 displays the image data of the selected maintenance part in time series. FIG. 3B displays a history of actual image data of a certain maintenance part. For example, IMG0 to IMG3 are image data of the same maintenance part, and are displayed in time series in order from IMG0, IMG1, IMG2, IMG3, and old image data. That is, the image data IMG0 is the oldest image data, and is the maintenance portion image data close to the initial state. The image data IMG1 is the next oldest image data after the image data IMG0, the image data IMG2 is the next oldest image data after the image data IMG1, and the image data IMG3 is the newest image data.

  Further, the display unit 100 displays the imaging date / time and the capturing date / time of the image data IMG0 to IMG3 associated with the image data IMG0 to MIMG3 together with the image data IMG0 to IMG3.

  Further, the display unit 100 may display the user comment field 103 together with the corresponding image data IMG0 to IMG3. The user comments are stored in the storage unit 63 in association with the image data IMG0 to IMG3.

  Thus, the display unit 100 represents a plurality of image data in a time series on a single screen, so that the user can easily grasp the state change (for example, deformation, wear, resin adhesion, etc.) of the maintenance part. be able to. As a result, the user can replace or repair the maintenance part at an appropriate time, and can suppress failure and excessive maintenance of the injection molding machine 1.

  The image IMG0 may be image data of an initial maintenance portion. In this case, the storage unit 63 stores in advance the image data in the initial state of the maintenance part. When the maintenance part is selected, the display unit 100 displays the image data IMG0 in the initial state of the maintenance part and the image data IMG1 to IMG3 after the start of use of the maintenance part side by side. The image data IMG1 to IMG3 are, for example, three pieces of image data captured most recently. Thereby, the user can confirm the present state of the maintenance part while comparing with the initial state.

  In addition, according to the present embodiment, the user can not only easily determine the part replacement timing of the maintenance part, but can also check the state of the maintenance part before and after replacement with the image data. Furthermore, since the storage unit 63 stores the history of image data, it can be used as a maintenance diary. In this case, even if the user switches to another user, the other user can easily grasp the status and replacement history of each maintenance part of the injection molding machine 1 by referring to the image data on the display unit 100. it can.

  When a plurality of industrial machines are connected via a network, a host computer (not shown) may collectively manage image data of the plurality of industrial machines. In this case, each industrial machine transmits image data to the host computer while storing its own image data. Thus, the user can easily grasp the state of the maintenance portion by referring to the image data of a plurality of industrial machines in the host computer.

  Further, according to the present embodiment, the image data is stored in the storage unit 63 provided in the injection molding machine 1 and displayed on the display unit 100 provided in the injection molding machine 1. Therefore, the user can check the past history of the maintenance part at the work site. Furthermore, although a camera and a camera-equipped terminal are required, other terminals that display a maintenance manual for maintenance are not necessary.

  In FIG. 3B, the display unit 100 divides one screen into four to display four image data simultaneously. However, the display unit 100 may display the history of image data by other methods. For example, the display unit 100 may display one image data on one screen and display the history of the image data in time series when the user scrolls the screen vertically or horizontally.

(Import image data)
When capturing image data from the user's terminal, the control unit 8 needs to classify the captured image data into corresponding maintenance parts and store them in the storage unit 63. For example, when the user transmits image data from the terminal, the control unit 8 displays an image data capturing screen on the display unit 100. The image data capture screen may be the screen of the figure of the injection molding machine 1 or the photograph 101 as in FIG. The display unit 100 makes it possible to select a maintenance part corresponding to the image data on the figure or photo screen of the injection molding machine 1. The user selects a maintenance portion corresponding to the image data to be transmitted on the display unit 100, and then transmits the image data from the terminal. Thereby, the control unit 8 can classify the received image data into the corresponding maintenance part and store it in the storage unit 63.

  Alternatively, the control unit 8 may select a maintenance portion corresponding to the image data after the image data is captured. For example, the user transmits image data from the terminal to the control unit 8. Upon receiving the image data, the control unit 8 causes the display unit 100 to display an image data registration screen. At this time, as shown in FIG. 4, the display unit 100 arranges the entire image or photograph 101 of the injection molding machine 1 and the image data IMG10 to IMG12 captured from the outside on the same screen as the image data registration screen. indicate. FIG. 4 is a diagram showing an image data capturing screen.

  The user drags one of the image data IMG10 to IMG12 on the display unit 100, and moves and drops the dragged image data to the corresponding maintenance portion of the entire view of the injection molding machine 1 or the photograph 101. This drag-and-drop operation is executed for each of the image data IMG10 to IMG12. Thereby, the memory | storage part 63 can store the image data IMG10-IMG12 on the display part 100 as image data of a corresponding maintenance part.

(Modification 1)
The injection molding machine 1 according to the above embodiment may further include a camera 90 as indicated by a broken line in FIG. The camera 90 is fixed to the frame 2 of the injection molding machine 1 for imaging the maintenance part, and is connected to the input / output unit 65 so as to be communicable. When the shutter of the camera 90 is pressed, the camera 90 automatically executes imaging of the maintenance part and transmission of image data to the input / output unit 65. Therefore, the image data of the maintenance part is automatically stored periodically in the storage unit 63 simply by pressing the shutter of the camera 90 periodically by the user.

  Preferably, a plurality of cameras 90 are provided corresponding to each of the plurality of maintenance portions. In this case, the plurality of cameras 90 transmit their identifiers together with the image data to the control unit 8. Thereby, the control part 8 can specify the camera 90 which imaged image data, and the maintenance part corresponding to image data. Therefore, the control unit 8 can automatically classify the image data for each maintenance portion and store the image data in the storage unit 63.

(Modification 2)
FIG. 5 is a diagram illustrating a screen of the display unit 100 of the injection molding machine 1 according to the second modification of the first embodiment.
