Description

Technical Field

[0001] The present disclosure relates to an injection molding machine and an injection molding machine system including the same, and more particularly to a technique for monitoring the motion of the injection molding machine. Background Art

[0002] Japanese Patent Application Laid-Open No. 2020-66152 discloses a management device that is communicatively connected to a plurality of injection molding machines, and collects operating status information of each injection molding machine to manage the operating status of the injection molding machine or the quality status of molded products. Summary of the invention

[0003] In a system having the above-mentioned management device, each injection molding machine regularly sends operating status information to the management device. In order for the management device to monitor the status of the injection molding machine as real-time as possible, it is necessary to send information from each injection molding machine to the management device at short time intervals.

[0004] In the injection molding machine, transmission control to the management device is performed simultaneously with product molding control. However, if data is frequently transmitted to the management device, memory usage time due to transmission control increases, which may affect the execution of molding control.

[0005] The present disclosure is made to solve such a problem, and an object of the present disclosure is to suppress the influence on molding control caused by sending information to a server in an injection molding machine system including an injection molding machine and a server for managing the injection molding machine.

[0006] The injection molding machine system according to the first aspect of the present disclosure includes an injection molding machine, a server and a terminal device. The server is configured to be able to communicate with the injection molding machine and store data representing the operation status of the injection molding machine. The terminal device is configured to be able to communicate with the server and display information from the server. The injection molding machine sends data to the server when it is at a predetermined timing and the injection molding machine is not in a molding action.

[0007] A control device according to a second aspect of the present disclosure is used in an injection molding machine configured to communicate with an external server. The control device includes a processor and a storage device storing a program executed by the processor. The processor executes the program to: i) cause the injection molding machine to perform a molding action, and ii) send data indicating the action state of the injection molding machine to the external server at a predetermined timing and when the injection molding machine is not in a molding action.

[0008] The control device according to the third aspect of the present disclosure is used in an injection molding machine configured to be able to communicate with an external server. The control device includes a molding control unit, a state management unit, and a communication unit. The molding control unit controls the molding action of the injection molding machine. The state management unit manages the action state of the injection molding machine. The communication unit sends data indicating the action state of the injection molding machine to the external server. The state management unit sends the above data to the external server via the communication unit when it is at a predetermined timing and the injection molding machine is not in the molding action.

[0009] A control method according to a fourth aspect of the present disclosure relates to a control method for an injection molding machine configured to be able to communicate with an external server. The control method includes: (a) a step of causing the injection molding machine to perform a molding action; (b) a step of determining whether a predetermined timing has been reached; (c) a step of determining whether the injection molding machine is in a molding action; and (d) a step of sending data indicating an action state of the injection molding machine to the external server when the predetermined timing is reached and the injection molding machine is not in a molding action.

[0016] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be noted that in the accompanying drawings, the same or corresponding parts are marked with the same reference numerals, and their descriptions are not repeated.

[0017] [Overview of injection molding machine system]

[0018] Figure 11 is a schematic diagram of an injection molding machine system 10 including an injection molding machine 100 according to an embodiment. The injection molding machine system 10 includes an internal server 20, a cloud server 30, and a terminal device 40 in addition to the injection molding machine 100. The injection molding machine 100, the internal server 20, the cloud server 30, and the terminal device 40 are configured to be able to communicate in a wired or wireless manner via a network 50 such as the Internet.

[0019] The internal server 20 and the cloud server 30 are, for example, general-purpose computers, and include a processor and a large-capacity storage device. The internal server 20 is a physical server provided in the enterprise that owns the injection molding machine 100. The internal server 20 can be connected to the injection molding machine 100 so as to be communicable via the enterprise's internal network, rather than an external network such as the network 50. The cloud server 30 is a virtual server built on the network 50, and the operator providing the cloud service owns and manages the equipment that builds the server.

[0020] The internal server 20 and the cloud server 30 periodically acquire data indicating the operating state of the injection molding machine 100 via the network 50, and store the acquired data in the storage device (DB). In the case where the internal server 20 and the cloud server 30 include a display device (not shown), the internal server 20 and the cloud server 30 can monitor the operating state of the injection molding machine 100 by displaying the stored data on the display device.

[0021] The terminal device 40 is, for example, a mobile communication terminal such as a smartphone or a tablet computer, or a general-purpose computer. The terminal device 40 can acquire information from the cloud server 30 via the network 50 to remotely monitor the operating state of the injection molding machine 100 .

[0022] It should be noted that in Figure 1 In the example of FIG. 1 , one injection molding machine 100 is shown as an injection molding machine included in the injection molding machine system 10, but the injection molding machine system 10 may also include a plurality of injection molding machines. In addition, although an example of a case where a system including an injection molding machine is described in this specification, the features of the present disclosure may also be applied to a system including other industrial machines such as a processing machine, a press device, an extrusion molding machine, a laser processing machine, and / or an industrial robot.

[0023] [Structure of injection molding machine]

[0024] Figure 21 is a diagram for explaining the structure of the injection molding machine 100 according to the present embodiment. It should be noted that, for the sake of convenience, the ground on which the injection molding machine 100 is installed is taken as the XY plane, and the direction perpendicular to the ground is taken as the Z-axis direction. Sometimes the positive direction of the Z-axis is referred to as the upper side or the top, and the negative direction of the Z-axis is referred to as the lower side or the bottom. It should be noted that, although the injection molding machine 100 in the present embodiment is shown as an example of a horizontal injection molding machine, it is not limited to a horizontal injection molding machine, and may also be a vertical injection molding machine.

[0025] Reference Figure 2 The injection molding machine 100 is configured to include a mold clamping device 110 for clamping a mold, an injection device 120 for melting and injecting an injection material, an operation panel 130, and a control device 140. Figure 2 In the figure, the mold clamping device 110 is arranged on the negative side of the X-axis with respect to the injection device 120.

[0026] The mold clamping device 110 includes a base 111, a fixed plate 112, a mold clamping housing 113, a movable plate 114, a tie rod 115, a mold clamping mechanism 116, molds 117 and 118, and a ball screw 119. The base 111 is set on the ground, and the fixed plate 112, the mold clamping housing 113, the movable plate 114 and other equipment are mounted on the upper surface of the base 111.

[0027] The fixed plate 112 is fixed to the end of the side close to the injection device 120 (i.e., the positive direction of the X-axis) on the base 111. The mold clamping housing 113 is provided on the base 111 at the end of the negative direction of the X-axis. The fixed plate 112 and the mold clamping housing 113 are connected by a tie rod 115 including a plurality of rods. The mold clamping housing 113 can move along the X-axis direction on the base 111.

[0028] The movable plate 114 is arranged on the base 111 between the fixed plate 112 and the mold clamping housing 113. The movable plate 114 is configured to be movable in the X-axis direction. The mold clamping housing 113 and the movable plate 114 are connected by a mold clamping mechanism 116. The mold clamping mechanism 116 has a toggle mechanism. The ball screw 119 is connected to the toggle mechanism, and the servo motor 151 arranged on the mold clamping housing 113 is driven to rotate the ball screw 119, so that the movable plate 114 can be relatively moved along the X-axis direction relative to the mold clamping housing 113. It should be noted that as the mold clamping mechanism 116, a direct-acting hydraulic cylinder driven by hydraulic pressure can also be used.

[0029] The molds 117 and 118 are respectively arranged on the movable platen 114 and the fixed platen 112. The molds 117 and 118 are arranged between the movable platen 114 and the fixed platen 112 so as to face each other. By moving the mold 117 along the X-axis direction using the mold clamping mechanism 116, the molds 117 and 118 can be brought into close contact or the mold 117 can be separated from the mold 118. In the following description, the process of changing the molds 117 and 118 from a state in which they are separated from each other to a state in which they are in close contact is referred to as a "mold clamping process". In addition, the process of changing the molds 117 and 118 from a state in which they are in close contact is referred to as a "mold opening process".

[0030] By filling the mold with molten material (resin) and cooling and solidifying the mold while the mold 117 and the mold 118 are in close contact through the mold closing process, a product of a desired shape can be molded. After the product is molded, by operating the protrusion mechanism (not shown) provided on the movable plate 114 while the mold 117 is separated from the mold 118 through the mold opening process, the molded product can be taken out from the mold 117. The protrusion mechanism is driven by a servo motor 152 provided on the movable plate 114. It should be noted that the process of taking out the product using the protrusion mechanism is called a "protrusion process".

[0031] The injection device 120 includes a base 121, a heating cylinder 122, a driving device 124, a hopper 125, a nozzle contact device 127, and a temperature sensor 128. The base 121 is set on the ground on the positive side of the X-axis direction of the base 111, and the driving device 124 is mounted on its upper surface. The driving device 124 is provided with servo motors 153 and 154.

[0032] A heating cylinder 122 extending in the X-axis direction is provided at the driving device 124. The heating cylinder 122 includes a heater (not shown) for heating the interior, a screw 123, and an injection nozzle 126. The screw 123 is configured to be driven by a servo motor 153 in the driving device 124, and can rotate with the X-axis direction as the rotation axis. In addition, the screw 123 is configured to be movable in the X-axis direction in the heating cylinder 122 by the servo motor 154. The injection nozzle 126 is provided at the end of the mold clamping device 110 side in the heating cylinder 122 (i.e., the end in the negative direction of the X-axis). The heating cylinder 122 heats and melts the bead-shaped resin material thrown from the hopper 125, and generates a molten material by kneading using the screw 123. In this way, the process of melting the resin material is called a "plasticizing process."

[0033] The nozzle contact device 127 is configured as a mechanism including a hydraulic cylinder or a mechanism using a ball screw, and connects the drive device 124 and the fixed plate 112 of the mold clamping device 110. In the case where the nozzle contact device 127 is configured as a mechanism including a ball screw, the nozzle contact device 127 is driven by the drive device 124, and the drive device 124 and the heating cylinder 122 are moved in the X-axis direction. By using the nozzle contact device 127, the injection nozzle 126 is brought into contact with the sprue bushing of the mold 118 in the mold clamping device 110, and the molten material is injected from the injection nozzle 126, so that the cavity of the molds 117 and 118 is filled with the molten material. The servo motor 154 applies pressure to the molten material by moving the screw 123 in the heating cylinder 122 in the negative direction of the X-axis, so that the injection of the molten material into the molds 117 and 118 and the pressure of the injected molten material are kept constant.

[0034] It should be noted that the configuration of the nozzle contact mechanism is not limited to the configuration in which the injection device is moved as a whole by a ball screw disposed between the fixed plate 112 and the drive device 124 as described above, and may also be other configurations. For example, the device frame and the fixed component at the rear of the heating cylinder may be connected by a ball screw, and the heating cylinder itself may be moved toward the mold. Alternatively, the sliding base on which the injection device is mounted may be connected to the device frame by a ball screw, and the injection device and the sliding base may be moved together so that the injection nozzle contacts the mold.

[0035] Note that the process of injecting the molten material into the molds 117 and 118 is referred to as an “injection process.” In addition, the process of keeping the molten material filled into the molds 117 and 118 at a constant pressure and cooling it after the injection process is referred to as a “pressure holding process.”

[0036] The temperature sensor 128 is provided near the injection nozzle 126 in the heating cylinder 122. The temperature sensor 128 detects the temperature of the molten material inside the heating cylinder 122 and outputs the temperature to the control device 140. The control device 140 controls the heater based on the detection value of the temperature sensor 128 to adjust the temperature of the molten material to a desired temperature.

[0037] After the pressure holding process is completed, the mold opening process and the protrusion process are carried out, and the molded product is taken out.

[0038] The injection molding machine 100 can continuously form a product by cyclically repeating a mold clamping process, an injection process, a pressure holding process, a plasticizing process, a mold opening process, and a protruding process.

[0039] The control device 140 is housed inside the base 121. The control device 140 typically includes a computing device 141, a storage device 142, and a servo amplifier 143 for driving servo motors 151 to 154. The computing device 141 is a CPU (Central Processing Unit) and / or a microcontroller. The storage device 142 includes volatile or non-volatile memories such as ROM (Read Only Memory) and RAM (Random Access Memory), and large-capacity storage devices represented by HDD (Hard Disc Drive) and SSD (Solid State Drive). The control device 140 obtains the detection values ​​of various sensors provided in the injection molding machine 100, and uniformly controls each device of the injection molding machine 100.

[0040] The operation panel 130 is a device for the operator to operate the injection molding machine 100, and includes a display device such as a liquid crystal display and an input device such as a keyboard. The operation panel 130 is connected to the control device 140, and can obtain and display the state of the injection molding machine 100 or output the user operation signal from the input device to the control device 140. The operation panel 130 can also be a touch panel in which the display device and the input device are integrated. In addition, the operation panel 130 can be installed on the base 111 or the base 121 of the injection molding machine 100, or it can be set at a position independent of the injection molding machine 100.

[0041] [Control device configuration]

[0042] Figure 3 yes Figure 2 The control device 140 includes a molding control unit 1401, a state management unit 1402, and a communication unit 1403.

[0043] The molding control unit 1401 includes Figure 2 The servo amplifier 143 described above drives the servo motor 150 included in the injection molding machine 100 .

[0044] The state management unit 1402 collects data indicating the operation state of the injection molding machine 100 and centrally manages the injection molding machine 100. The state management unit 1402 obtains information such as command values ​​and current values ​​from the molding control unit 1401 to each servomotor, and obtains detection values ​​from various sensors 160 provided in the injection molding machine 100. In addition, the state management unit 1402 also obtains operation information from the operator input from the input device 131 of the operation panel 130.

[0045] The state management unit 1402 displays the acquired information on the display device 132 of the operation panel 130 to notify the operator of the operating status of the injection molding machine 100. In addition, the state management unit 1402 determines whether there is an abnormality in the injection molding machine 100 based on the acquired information, and notifies the operator of an alarm via the display device 132.

[0046] The communication unit 1403 is an interface for communicating with the internal server 20 and the cloud server 30 via the network 50. The state management unit 1402 uploads various information acquired from the injection molding machine 100 and information indicating the operating state (log data) including detected abnormal information to the internal server 20 and the cloud server 30 through the communication unit 1403.

[0047] The internal server 20 and the cloud server 30 store the log data uploaded from the injection molding machine 100 in the storage device. Figure 1 As described, in response to a request from an external terminal device 40, the log data stored in the cloud server 30 is appropriately sent to the terminal device 40. Thus, the user of the terminal device 40 can remotely monitor the state of the injection molding machine 100. In addition, when an abnormality occurs in the injection molding machine 100, the cloud server 30 can send an alarm to the terminal device 40.

[0048] [Data upload process to the server]

[0049] The upload process of the log data from the injection molding machine 100 to the server can be set to be transmitted regularly at predetermined time intervals starting from the start of the injection molding machine 100. The predetermined time interval is, for example, 30 seconds, 1 minute, 5 minutes, or 10 minutes.

[0050] In order to remotely monitor the state of the injection molding machine 100 as real-time as possible, it is necessary to upload log data at relatively short time intervals. However, since the injection molding machine 100 also performs the molding operation which is the original function of the device, if the data transmission interval is shortened, the data upload timing may arrive during the execution of the molding operation.

[0051] In the control device 140, there is a case where the control program for performing the molding action and the control program for uploading the log data share the same memory. In this case, if the upload process is frequently performed, the time occupied by the shared memory by the control program for uploading increases, which may cause the molding action to be unsmooth. If this happens, there is a risk that the display of the display device 132 will be delayed or the parameters cannot be set through the input device 131. As a result, the delay in the execution time of each process causes a cycle delay, which may cause a decrease in the operating rate of the device or a quality defect.

[0052] Therefore, in this embodiment, when the upload timing arrives during the execution of the cyclic action (cyclic operation period) by the injection molding machine 100, the upload process is suspended or delayed, and the molding action is performed preferentially. Thus, even if there is a possibility of delay in updating the information during monitoring in the external terminal device 40, the influence on the molding control of the injection molding machine 100 can be suppressed. Therefore, it is possible to prevent the reduction of the operating rate of the device and / or the occurrence of quality defects.

[0053] Figure 4 This is a sequence diagram for explaining an example of the operation of the upload process to the server in the embodiment. Figure 4 The horizontal axis represents time, and the vertical axis represents the power state of the injection molding machine 100, the signal of the internal timer of the control device 140, the operation state of the cycle, and the execution state of the upload process.

[0054] When the injection molding machine 100 is powered on at time t1 , the control device 140 generates a start pulse for starting the upload process to the server at every predetermined time interval T1 .

[0055] When the cycle action starts at time t2, the control device 140 turns on the "molding flag" indicating that the cycle action is in progress. When the upload timing arrives at time t3 during the cycle execution, a start pulse for transmission is output, but since the molding flag is ON at time t3, the upload process is not performed (dashed line LN11).

[0056] After that, when the cycle action ends at time t4 and the upload timing arrives at time t5 until time t6 when the next cycle action starts, the control device 140 performs the upload process to the server (solid line LN12) because the molding flag is OFF. Thus, the log data is sent to the internal server 20 and the cloud server 30.

[0057] In the loop operation (i.e., the forming flag is ON), at time t7 and time t10 when the upload timing arrives, the upload process is terminated as in the case of time t3. In addition, when the forming flag is OFF, the upload process is executed at time t12 when the upload timing arrives.

[0058] By executing such a process, it is possible to suppress a decrease in operating rate and / or occurrence of quality defects due to a delay in the molding operation caused by the upload process.

[0059] It should be noted that in Figure 4In the example of , the upload process is suspended when the upload timing arrives during the cyclic action. However, it can also be set so that when the start pulse from the timer overlaps with the forming flag, the upload process is delayed until the cyclic action is completed. In this case, the upload process starts immediately after the cyclic action is completed. In this way, it is possible to prevent the delay of data update during external monitoring due to the continuous suspension of the upload process.

[0060] Figure 5 This is a flowchart of the upload process executed by the control device 140 of the injection molding machine 100. This flowchart is called from a main program (not shown) and executed in each control cycle of the control device 140, for example.

[0061] When the injection molding machine 100 is powered on and started, the control device 140 determines whether the start pulse of the upload timing is ON in step (hereinafter referred to as “S”) 100 .

[0062] When the start pulse is OFF (No in S100 ), since it is not the upload timing, the control device 140 skips the subsequent processing and returns the processing to the main routine.

[0063] On the other hand, when the start pulse is ON (YES in S100), the control device 140 determines that the log data upload timing has arrived. Then, the control device 140 determines in S110 whether the molding flag is OFF, that is, whether the cycle operation is not being performed.

[0064] When the molding flag is OFF (YES in S110 ), since the loop operation is not in progress, the control device 140 advances the process to S120 and uploads the collected log data to the internal server 20 and the cloud server 30 via the network 50 .

[0065] On the other hand, when the molding flag is ON (No in S110 ), the control device 140 skips the subsequent steps and returns the processing to the main routine in order to prevent the molding operation from being affected.

[0066] It should be noted that, in the case where the upload process is delayed until the cycle is completed instead of terminating the upload process, the control device 140 advances the process to the next step when it is determined that the molding flag is ON (“No” in S110). Figure 5 S115 is indicated by the dotted line in FIG. In S115, the control device 140 monitors the transition of the molding flag from ON to OFF, and when the molding flag turns OFF, the control device 140 advances the process to S120 and executes the upload process.

[0067] By performing control according to the above process, it is possible to prevent the injection molding machine 100 from executing the upload process during the molding operation. Therefore, it is possible to suppress the influence on the molding control caused by sending information to the server.

[0068] It should be noted that, if the start condition of the shaping action is met during the execution of the upload process, the upload process can be temporarily interrupted, and the remaining data can be sent after the cycle action is completed. Alternatively, if more than 50% of the log data has been sent and the remaining data will be sent in a relatively short time, even if the start condition of the shaping action is met, the upload process can be continued, and the shaping action can be started after the log data is sent.

[0069] In addition, the timer for determining the upload timing can be set at the input device 131 in the injection molding machine 100. In addition, it is also possible that the timer can be remotely set from any one of the internal server 20, the cloud server 30 and / or the terminal device 40.

[0070] The “cloud server 30 ” in the embodiment corresponds to the “server” and the “external server” in the present disclosure.
