[0009] A. First embodiment: 1 is a block diagram showing a schematic configuration of a molding machine management system 90 in the first embodiment. The molding machine management system 90 includes an injection molding machine 10 that molds a molded product, a removal machine 20 that removes the molded product, an inspection device 30 that inspects the molded product, and a management server 50.

[0010] The injection molding machine 10 has a first control unit 110 and a molding die 160. The molding die 160 includes a fixed die and a movable die. A metal mold or a resin mold is used as the molding die 160. A detailed configuration of the injection molding machine 10 will be described later. The first control unit 110 is configured by a computer having one or more processors, a memory, and an input / output interface for inputting and outputting signals to and from the outside. The first control unit 110 controls each part of the injection molding machine 10 to perform injection molding and mold a molded product. A second control unit 210 of the take-out machine 20 and a third control unit 310 of the inspection device 30, which will be described later, have the same configuration as the first control unit 110.

[0011] The take-out machine 20 is composed of a second control unit 210 and a take-out robot 220. The second control unit 210 controls the operation of the take-out robot 220. The take-out robot 220 is a robot that takes out a molded product from the molding die 160 of the injection molding machine 10. The take-out robot 220 of this embodiment grasps and takes out the molded product, which has been released from the molding die 160 by an ejector pin provided in the injection molding machine 10, with an end effector attached to the tip of the arm of the take-out robot. The take-out robot 220 places the taken out molded product on a tray. The tray on which the molded product is placed is transported to the inspection device 30 by a transport device (not shown) or the take-out robot 220.

[0012] The inspection device 30 is composed of a third control unit 310 and a sensor 320. The sensor 320 in this embodiment is an image sensor. The third control unit 310 controls the sensor 320 to capture an image of the molded product, and performs an appearance inspection of the molded product by analyzing the captured image of the molded product. The third control unit 310 judges the presence or absence of an abnormality in the appearance of each molded product by an appearance inspection using the image. The judgment result of the abnormality is hereinafter referred to as the inspection result. The inspection device 30 transmits the inspection result to the management server 50. The inspection result may include the image used in the inspection. The sensor 320 can be various sensors such as a contact sensor or a non-contact sensor depending on the type of inspection.

[0013] Fig. 2 is a front view showing a schematic configuration of the injection molding machine 10. Arrows indicating mutually orthogonal X, Y, and Z directions are shown in Fig. 2. The X and Y directions are parallel to the horizontal plane, and the Z direction is opposite to the direction of gravity.

[0014] The injection molding machine 10 includes a molding die 160, an injection unit 100, and a clamping unit 170. The injection unit 100 is also called a plasticizing unit. The molding die 160 is attached to the clamping unit 170. The injection unit 100 and the clamping unit 170 are each fixed to a base 11. The base 11 includes a first control unit 110.

[0015] The injection section 100 is connected to a material input section 15 into which the material of the molded product is input. The material input section 15 in this embodiment is configured by a hopper that temporarily stores the material. For example, a thermoplastic resin formed into pellets is used as the material of the molded product. The injection section 100 plasticizes the material supplied from the material input section 15 to make it a molten material, and injects the molten material into a molding die 160 attached to a mold clamping section 170. Note that the material input section 15 is not limited to a hopper, and for example, a tube through which the material is pressure-fed can also be used.

[0016] Fig. 3 is an explanatory diagram showing the internal configuration of the injection molding machine 10. The X, Y, and Z directions shown in Fig. 3 correspond to the X, Y, and Z directions shown in Fig. 2. The injection section 100 includes a melting section 120, an injection control section 150, and a nozzle 156.

[0017] The melting section 120 includes a case 121, a first driving section 122, a flat screw 130, a barrel 140, a heating section 165, and a check valve 149. The melting section 120 plasticizes at least a portion of the material supplied from the material input section 15, generates a paste-like molten material having fluidity, and guides the paste-like molten material to the injection control section 150.

[0018] The flat screw 130 has a generally cylindrical shape whose height in the direction along the central axis RX is smaller than its diameter. The flat screw 130 is accommodated in a space surrounded by the case 121 and the barrel 140. The flat screw 130 has a groove forming surface 132 that is generally perpendicular to the central axis RX on an end surface facing the barrel 140. A spiral or helical groove 135 is formed on the groove forming surface 132. The groove forming surface 132 of the flat screw 130 faces an opposing surface 142 of the barrel 140 that is generally perpendicular to the central axis RX. A first drive unit 122 equipped with a motor and a reducer is connected to the surface of the flat screw 130 opposite to the groove forming surface 132. The flat screw 130 rotates about the central axis RX by the torque generated by the first drive unit 122. The first drive unit 122 is driven under the control of the first control unit 110.

[0019] The melting section 120 heats the material supplied between the groove 135 of the flat screw 130 and the barrel 140 by the heating section 165 while rotating the flat screw 130 relative to the barrel 140, thereby transporting the material to the communication hole 146 and plasticizing the material. The plasticized material then flows from the communication hole 146 to the injection control section 150 and the nozzle 156. A check valve 149 is provided in the communication hole 146. The check valve 149 prevents the material from flowing back from the communication hole 146 to the groove 135 of the flat screw 130.

[0020] The injection control unit 150 includes a cylinder 151, a plunger 152, and a second driving unit 153. The cylinder 151 is a substantially cylindrical member connected to the communication hole 146 of the barrel 140. The plunger 152 moves inside the cylinder 151. The plunger 152 is driven by the second driving unit 153 which is constituted by a motor, gears, etc. The second driving unit 153 is controlled by the first control unit 110.

[0021] Under the control of the first control unit 110, the injection control unit 150 executes a metering operation and an injection operation by sliding the plunger 152 in the cylinder 151. The metering operation refers to an operation of moving the plunger 152 in a direction away from the communication hole 146 to guide the molten material in the communication hole 146 into the cylinder 151 and measuring it in the cylinder 151. The injection operation refers to an operation of moving the plunger 152 in a direction approaching the communication hole 146 to inject the molten material in the cylinder 151 into the molding die 160 through the nozzle 156. The first control unit 110 controls the movement of the plunger 152 so as to achieve an injection pressure determined by the molding conditions.

[0022] The nozzle 156 communicates with the communication hole 146. By executing the above-mentioned metering operation and injection operation, the molten material measured in the cylinder 151 is sent from the injection control unit 150 to the nozzle 156 through the communication hole 146. The nozzle 156 is provided with a heater (not shown), and the temperature of the nozzle 156 is adjusted by controlling the heater by the first control unit 110. In addition, the nozzle 156 is provided with a sensor that measures the temperature of the nozzle 156 and the injection pressure of the nozzle 156. The temperature and injection pressure of the nozzle 156 measured by the sensor are acquired by the first control unit 110 and transmitted to the management server 50.

[0023] The molten material sent to the nozzle 156 is injected from the nozzle 156 into a cavity 164 of a molding die 160. The molding die 160 has a movable die 162 and a fixed die 163 that face each other, and has a cavity 164 between them. The cavity 164 is defined by uneven shapes formed on the movable die 162 and the fixed die 163.

[0024] A temperature adjustment device (not shown) is connected to the molding die 160. The temperature adjustment device is controlled by the first control unit 110. The first control unit 110 controls the temperature adjustment device to flow a heat medium inside or around the molding die 160, thereby adjusting the temperature of the molding die 160. The molding die 160 is provided with a temperature sensor that measures the temperature of the molding die 160, and a mold clamping force sensor. The temperature measured by the temperature sensor and the mold clamping force measured by the mold clamping force sensor are acquired by the first control unit 110 and transmitted to the management server 50.

[0025] The mold clamping unit 170 is equipped with a third drive unit 171 having a motor and a ball screw 172. The ball screw 172 is connected to the movable mold 162. The drive of the third drive unit 171 is controlled by the first control unit 110. The ball screw 172 transmits power from the motor to the movable mold 162. Under the control of the first control unit 110, the mold clamping unit 170 moves the movable mold 162 by the third drive unit 171, thereby performing a mold clamping operation of the molding mold 160 with a mold clamping force determined by the molding conditions, and a mold opening operation. When the molding mold 160 is opened, the molded product is released from the cavity 164 by the ejector pin 181.

[0026] The injection molding machine 10 is equipped with a first camera 16 that photographs the molding die 160. The first camera 16 is controlled by a first control unit 110. The first control unit 110 uses the first camera 16 to photograph the operation of the molding die 160 for each shot, more specifically, the operation of the movable die 162 from mold opening to mold closing for each shot, and transmits the photographed video data to the management server 50 as first video data.

[0027] The injection molding machine 10 is equipped with a second camera 17 that captures an image of the third driving unit 171. The second camera 17 is controlled by the first control unit 110. The first control unit 110 uses the second camera 17 to capture an image of the operation of the ball screw 172 for each shot, more specifically, the operation of the ball screw 172 from mold opening to mold closing for each shot, and transmits the captured video data to the management server 50 as second video data.

[0028] Returning to Fig. 2 for the explanation, the injection molding machine 10 of this embodiment is equipped with a third camera 18 that captures images of the material input section 15, in addition to the first camera 16 and the second camera 17. The third camera 18 is controlled by the first control section 110. The first control section 110 uses the third camera 18 to capture images of the state of material supply in the material input section 15 for each shot, and transmits the captured video data to the management server 50 as third video data.

[0029] Returning to FIG. 1 for the explanation, the management server 50 can communicate with the injection molding machine 10, the extractor 20, and the inspection device 30 via a network 80. The network 80 may be, for example, a LAN, a WAN, or the Internet. A display unit 60 is connected to the management server 50. For example, a liquid crystal display or an organic EL display is used as the display unit 60. Alternatively, for example, a tablet terminal or a mobile terminal connected to the management server 50 via the network 80 may be used as the display unit 60.

[0030] The management server 50 includes a control unit 510 and a storage unit 520. The control unit 510 is configured by a computer including one or more processors, a memory, and an input / output interface for inputting and outputting signals from and to the outside. The storage unit 520 stores a computer program 521 for controlling the molding machine management system 90 and a video database 522. The control unit 510 loads the computer program stored in the storage unit 520 into the memory and executes it, thereby causing the management server 50 to realize a function of acquiring video data, a function of recording the video data in the video database 522 in association with the shot number, and a function of displaying the video data on the display unit 60 in association with the shot number. The computer program 521 may be recorded on a computer-readable recording medium such as a memory card or an optical disk.

[0031] Control unit 510 acquires the shot numbers, the measurement values ​​corresponding to the shot numbers, and the first to third video data from injection molding machine 10 via network 80. The measurement values ​​include various values ​​measured in injection molding machine 10, such as the nozzle temperature, injection pressure, mold temperature, and mold clamping force, as described above. Control unit 510 also acquires the inspection results of the molded product from inspection device 30 in the order of shot numbers via network 80. Control unit 510 records these acquired data and values ​​in video database 522 stored in storage unit 520.

[0032] 4 is a diagram showing a data structure of video database 522 stored in storage unit 520. Video database 522 records lot numbers. The lot numbers are determined according to the manufacturing time, such as the manufacturing date, manufacturing week, or manufacturing month. Video database 522 associates the lot numbers with molding condition data indicating the molding conditions set in injection molding machine 10 for the lot. The molding condition data includes nozzle temperature, mold temperature, injection pressure, mold clamping force, and the like.

[0033] Furthermore, the lot number is associated with the shot number of each shot in which injection molding was performed in that lot. The first video data, the second video data, and the third video data are associated with the shot number as video data. Furthermore, in addition to the video data, each shot number is associated with the measurement value for each shot number acquired from the injection molding machine 10 and the inspection result acquired from the inspection device 30. When the lot number is changed in the management server 50, the control unit 510 of the management server 50 transmits a predetermined command to the injection molding machine 10 to initialize the shot number.

[0034] 5 is a flowchart of a video display process executed by the control unit 510 of the management server 50. This process is executed when the control unit 510 receives a predetermined operation from an administrator through a predetermined input device such as a touch panel or a mouse connected to the management server 50. This process may be executed while a molding cycle is being performed in the molding machine management system 90, or may be executed when the molding cycle is stopped.

[0035] In step S10, control unit 510 acquires a lot number and a shot number from the administrator via the input device.

[0036] In step S20, control unit 510 obtains from video database 522 the video data, measurement values, and inspection results corresponding to the lot number and shot number obtained in step S10, together with the molding condition data corresponding to the lot number.

[0037] In step S30, the control unit 510 causes the display unit 60 to display each of the data acquired in step S20, i.e., the video data, the measurement values, and the inspection results. Furthermore, the control unit 510 causes the display unit 60 to display the lot number and shot number acquired from the administrator in step S10, and the molding conditions represented by the molding condition data acquired in step S20.

[0038] FIG. 6 is a diagram showing an example of the display contents of the display unit 60. As shown in FIG. 6, the control unit 510 displays the video data acquired from the video database 522, that is, the first video data, the second video data, and the third video data, on the display unit 60. In this embodiment, the control unit 510 displays the video data of the mold 160 represented by the first video data, the video data of the ball screw 172 represented by the second video data, and the video data of the material input unit 15 represented by the third video data, in a switchable manner by a tab control represented by a graphical interface in the lower part of the screen. That is, in this embodiment, one of the first video data, the second video data, and the third video data selected by the administrator is displayed on the display unit 60. FIG. 6 shows an example in which the first video data MD1 is displayed. Furthermore, the control unit 510 displays the lot number, the shot number, the molding conditions, the inspection results, and the measurement values ​​on the same screen as the video data in the upper part of the screen. In addition to these pieces of information, the control unit 510 may also display, for example, values ​​of control limit lines and specification values ​​on the display unit 60 as numerical information used for quality control of the molded product. The control limit lines include an upper control limit line, a center line, and a lower control limit line, and the specification values ​​include an upper specification value and a lower specification value.

[0039] FIG. 7 is a diagram showing another example of the display contents of the display unit 60. FIG. 6 shows an example in which the first, second, and third video data are switchably displayed, but the control unit 510 may simultaneously display the first, second, and third video data MD1, MD2, and MD3 on the same screen as shown in FIG. 7. In addition to such a display, the control unit 510 may simultaneously display two of the first, second, and third video data MD1, MD2, and MD3 on the same screen and display the remaining one video data on a separate screen. The separate screen may be, for example, a display unit different from the display unit 60, or a separate window displayed on the display unit 60, or at least the first and second video data MD1 and MD2 may be synchronously played back.

[0040] According to the molding machine management system 90 of the present embodiment described above, the video data of the mold 160 and the video data of the third drive unit 171 are displayed on the display unit 60 in association with the shot number, so that it becomes easier to identify the cause of molding abnormality that cannot be confirmed only by the video data of the mold 160, for example, when an abnormality occurs in a molded product due to a cause such as an external load applied to a drive unit provided in the injection molding machine 10. Therefore, it is possible to appropriately formulate measures to prevent recurrence of molding abnormality without taking ad hoc measures such as changing molding conditions. In the present embodiment, the control unit 510 displays the video data of the ball screw 172 provided in the injection molding machine 10, so that it becomes easier for the manager to identify the cause of molding defects, for example, contact of a foreign object with the ball screw 172, and to appropriately deal with the cause.

[0041] In this embodiment, the video data of the material input unit 15 is displayed on the display unit 60 as the third video data. Therefore, it becomes easier to identify molding abnormalities caused by a malfunction of the material input unit 15, such as clogging of material in the material input unit 15.

[0042] In this embodiment, the molding conditions of the injection molding machine 10 are also displayed on the same screen as the video data. Therefore, if the molding conditions are the cause of the abnormality, it is easy to analyze the cause of the abnormality. Furthermore, in this embodiment, the inspection results and each measurement value of the injection molding machine 10 are also displayed on the same screen, so the cause of the molding abnormality can be analyzed from various perspectives.

[0043] B. Other embodiments: (B1) In the above embodiment, the control unit 510 of the injection molding machine 10 uses the first camera 16 to capture an image of the movable mold 162 as the first video data. In contrast, the first camera 16 may capture an image of the fixed mold 163. Also, a plurality of first cameras 16 may be provided to capture video data of both the movable mold 162 and the fixed mold 163. In this case, the control unit 510 may cause the display unit 60 to switch between displaying the video data of the movable mold 162 and the video data of the fixed mold 163, or to display them simultaneously.

[0044] (B2) In the above embodiment, the control unit 510 displays the video data of the material input unit 15 on the display unit 60. However, it is not essential to display the video data of the material input unit 15. For example, the control unit 510 may display the video data of the movable type, the fixed type, and the video data of the drive unit on the display unit 60 without displaying the video data of the material input unit 15 on the display unit 60.

[0045] (B3) In the above embodiment, the control unit 510 captures, as the second video data, the operation of the ball screw 172 provided in the third drive unit 171. In contrast, the control unit 510 may capture, as the second video data, the operation of the first drive unit 122 and the second drive unit 153 provided in the injection unit 100 as the drive units. This makes it easier to identify molding abnormalities caused by a malfunction of the drive units provided in the injection unit 100.

[0046] (B4) In the above embodiment, the control unit 510 displays the molding conditions together with the video data, but displaying the molding conditions is not essential. Also, the control unit 510 does not have to display the lot number, the inspection results, or the measurement values. These data may be displayed on a screen separate from the video data.

[0047] (B5) In the above embodiment, the injection molding machine 10 is equipped with a flat screw 130 in the injection unit 100. In contrast, the injection unit 100 may be equipped with an in-line screw instead of the flat screw 130. In this case, the second camera 17 captures, for example, an image of a drive unit that rotates the screw or a drive unit that moves the screw in the axial direction.

[0048] (B6) In the above embodiment, the storage unit 520 may be provided in a storage device separate from the management server 50, for example, a file server or a NAS (Network Attached Storage).

[0049] (B7) The first control unit 110 may transmit an imaging start signal to the first camera 16 and the second camera 17 when transmitting a predetermined operation signal of the injection molding machine 10. The predetermined operation signal is, for example, a mold closing operation signal to the mold clamping unit 170, a shot start signal to the plunger 152, a material supply signal to the material input unit 15, etc. This makes it possible to appropriately synchronize the imaging start timing of the first video data and the imaging timing of the second video data.

[0050] (B8) In the above embodiment, the injection molding machine 10 is equipped with a third camera 18 that photographs the material feeding section 15, in addition to the first camera 16 and the second camera 17, but the remover 20 or the inspection device 30 may be equipped with multiple cameras.
