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 techniques for monitoring the operation of an injection molding machine. [Background technology]

[0002] Japanese Patent Laid-Open Publication No. 2020-66152 (Patent Document 1) discloses a management device communicably connected to multiple injection molding machines. The management device collects operation status information from each injection molding machine and manages the operation status of the injection molding machine or the quality state of the molded product. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-66152 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a system having such a management device, each injection molding machine periodically transmits operating status information to the management device. In order for the management device to monitor the status of the injection molding machine as quickly as possible in real time, it is necessary for each injection molding machine to transmit information to the management device at relatively short intervals.

[0005] In an injection molding machine, in addition to controlling the molding of the product, transmission control to a management device is also performed. However, if data is sent to the management device frequently, the memory occupancy time for transmission control will increase, which may affect the execution of molding control.

[0006] The present disclosure has been made to solve such problems, and its purpose is to suppress the impact on molding control caused by information transmission to a server in an injection molding machine system having an injection molding machine and a server for managing the injection molding machine. [Means for solving the problem]

[0007] An injection molding machine system according to a 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 stores data indicating an operating state of the injection molding machine. The terminal device is configured to be able to communicate with the server and displays information from the server. The injection molding machine transmits data to the server at a predetermined timing when the injection molding machine is not in a molding operation.

[0008] A control device according to a second 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 processor and a storage device storing a program executed by the processor. By executing the program, the processor i) causes the injection molding machine to perform a molding operation, and ii) transmits data indicating the operating state of the injection molding machine to the external server at a predetermined timing when the injection molding machine is not performing a molding operation.

[0009] A control device according to a 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 status management unit, and a communication unit. The molding control unit controls the molding operation of the injection molding machine. The status management unit manages the operating status of the injection molding machine. The communication unit transmits data indicating the operating status of the injection molding machine to the external server. The status management unit transmits the data to the external server via the communication unit at a predetermined timing and when the injection molding machine is not performing a molding operation.

[0010] 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 including the steps of (a) causing the injection molding machine to execute a molding operation, (b) determining whether a predetermined timing has been reached, (c) determining whether the injection molding machine is in a molding operation, and (d) transmitting data indicating an operation state of the injection molding machine to the external server when the predetermined timing has been reached and the injection molding machine is not in a molding operation. Effect of the Invention

[0011] In the injection molding machine of the present disclosure, data indicating the operating status is transmitted to a higher-level server on the condition that the injection molding machine is not in a molding operation. In other words, when the injection molding machine is in a molding operation, data is not transmitted from the injection molding machine to the server. Therefore, it is possible to suppress the influence of information transmission to the server on molding control. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0014] [Outline of injection molding machine system] 1 is a schematic diagram of an injection molding machine system 10 including an injection molding machine 100 according to an embodiment. In addition to the injection molding machine 100, the injection molding machine system 10 includes an intraserver 20, a cloud server 30, and a terminal device 40. The injection molding machine 100, the intraserver 20, the cloud server 30, and the terminal device 40 are configured to be able to communicate with each other via a network 50 such as the Internet, either wired or wirelessly.

[0015] The intraserver 20 and the cloud server 30 are, for example, general-purpose computers, and include a processor and a large-capacity storage device. The intraserver 20 is a physical server located in a company that owns the injection molding machine 100. The intraserver 20 may be communicatively connected to the injection molding machine 100 via a company intranet instead of an external network such as the network 50. The cloud server 30 is a virtual server built on the network 50, and the business operator providing the cloud service owns and manages the equipment that builds the server.

[0016] The intraserver 20 and the cloud server 30 periodically acquire data indicating the operating status of the injection molding machine 100 via the network 50, and store the acquired data in a storage device (DB). If the intraserver 20 and the cloud server 30 include a display device (not shown), the intraserver 20 and the cloud server 30 can monitor the operating status of the injection molding machine 100 by displaying the stored data on the display device.

[0017] The terminal device 40 is, for example, a mobile communication terminal such as a smartphone or a tablet, or a general-purpose computer. The terminal device 40 can remotely monitor the operating status of the injection molding machine 100 by acquiring information from the cloud server 30 via the network 50.

[0018] 1, one injection molding machine 100 is shown as the injection molding machine included in the injection molding machine system 10, but multiple injection molding machines may be included in the injection molding machine system 10. Also, in this specification, an example of a system including an injection molding machine will be described, but the features of the present disclosure are also applicable to systems including other industrial machines, such as machine tools, press machines, extruders, laser processing machines, and / or industrial robots.

[0019] [Injection molding machine configuration] 2 is a diagram for explaining the configuration of the injection molding machine 100 according to the embodiment. For convenience of explanation, the floor surface on which the injection molding machine 100 is placed is defined as an XY plane, and the direction perpendicular to the floor surface is defined as a Z-axis direction. The positive direction of the Z-axis may be referred to as the upper side or upward, and the negative direction as the lower side or downward. Note that the injection molding machine 100 in the embodiment is shown as a horizontal injection molding machine by way of example, but is not limited to a horizontal injection molding machine and may be a vertical injection molding machine.

[0020] 2, injection molding machine 100 includes a clamping unit 110 for clamping a mold, an injection unit 120 for melting and injecting an injection material, an operation panel 130, and a control unit 140. In Fig. 2, clamping unit 110 is disposed on the negative side of the X-axis with respect to injection unit 120.

[0021] The mold clamping device 110 includes a bed 111, a fixed platen 112, a mold clamping housing 113, a movable platen 114, tie bars 115, a mold clamping mechanism 116, molds 117 and 118, and a ball screw 119. The bed 111 is placed on the floor surface, and devices such as the fixed platen 112, the mold clamping housing 113, and the movable platen 114 are mounted on the upper surface of the bed 111.

[0022] The fixed platen 112 is fixed to the end of the bed 111 closer to the injection unit 120 (i.e., in the positive direction of the X-axis). The mold clamping housing 113 is disposed at the end of the bed 111 in the negative direction of the X-axis. The fixed platen 112 and the mold clamping housing 113 are connected by a tie bar 115 including a plurality of bars. The mold clamping housing 113 is movable on the bed 111 in the X-axis direction.

[0023] The movable platen 114 is disposed on the bed 111 between the fixed platen 112 and the clamping housing 113. The movable platen 114 is configured to be movable in the X-axis direction. The clamping housing 113 and the movable platen 114 are connected by a clamping mechanism 116. The clamping mechanism 116 has a toggle mechanism. A ball screw 119 is connected to the toggle mechanism, and the movable platen 114 can be moved in the X-axis direction relative to the clamping housing 113 by driving a servo motor 151 disposed in the clamping housing 113 to rotate the ball screw 119. Note that a direct acting cylinder driven by hydraulic pressure may be used as the clamping mechanism 116.

[0024] Molds 117 and 118 are disposed on the movable platen 114 and the fixed platen 112, respectively. The mold 117 and the mold 118 are disposed between the movable platen 114 and the fixed platen 112, facing each other. By moving the mold 117 in the X-axis direction using the mold clamping mechanism 116, the mold 117 and the mold 118 can be brought into close contact with each other, or the mold 117 can be separated from the mold 118. In the following description, the process of shifting the mold 117 and the mold 118 from a separated state to a close contact state is referred to as a "mold clamping process". Also, the process of shifting the mold 117 and the mold 118 from a close contact state to a separated state is referred to as a "mold opening process".

[0025] With the mold 117 and the mold 118 in close contact with each other in the mold clamping process, the inside of the mold is filled with molten material (resin), which is cooled and solidified, thereby molding a product of a desired shape. After the product is molded, with the mold 117 separated from the mold 118 in the mold opening process, the molded product can be removed from the mold 117 by operating an ejection mechanism (not shown) arranged on the movable platen 114. The ejection mechanism is driven by a servo motor 152 arranged on the movable platen 114. The process of removing the product using the ejection mechanism is referred to as the "ejection process."

[0026] The injection device 120 includes a base 121, a heating cylinder 122, a driving device 124, a hopper 125, a nozzle touch device 127, and a temperature sensor 128. The base 121 is placed on the floor surface on the positive side of the X-axis of the bed 111, and the driving device 124 is mounted on the upper surface thereof. Servo motors 153 and 154 are arranged in the driving device 124.

[0027] The driving device 124 is provided with a heating cylinder 122 extending in the X-axis direction. The heating cylinder 122 includes a heater (not shown) for heating the inside, a screw 123, and an injection nozzle 126. The screw 123 is driven by a servo motor 153 in the driving device 124 and configured to be rotatable around the X-axis direction as a rotation axis. The screw 123 is also configured to be movable in the X-axis direction within the heating cylinder 122 by the servo motor 154. The injection nozzle 126 is provided at the end of the heating cylinder 122 on the clamping device 110 side (i.e., the end in the negative direction of the X-axis). The heating cylinder 122 heats and melts the bead-shaped resin material fed from the hopper 125, and kneads it using the screw 123 to generate a molten material. The process of melting the resin material in this manner is called a "plasticization process."

[0028] The nozzle touch device 127 is configured by, for example, a mechanism using a hydraulic cylinder or a mechanism using a ball screw, and connects the drive device 124 and the fixed platen 112 of the mold clamping device 110. When the nozzle touch device 127 is configured by a mechanism using a ball screw, the nozzle touch device 127 is driven by the drive device 124 to move the drive device 124 and the heating cylinder 122 in the X-axis direction. The nozzle touch device 127 brings the injection nozzle 126 into contact with the sprue bush of the mold 118 in the mold clamping device 110, and injects the molten material from the injection nozzle 126, thereby filling the cavity of the mold 117, 118 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, and injects the molten material into the mold 117, 118 and keeps the pressure of the molten material constant after injection.

[0029] The configuration of the nozzle touch mechanism is not limited to the above-mentioned configuration in which the entire injection device is moved by a ball screw arranged between the fixed platen 112 and the driving device 124, and other configurations may be used. For example, a configuration in which a ball screw is used to connect the device frame and a fixed member at the rear of the heating cylinder, and the heating cylinder itself is moved toward the mold, may be used. Alternatively, a configuration in which a ball screw is used to connect a slide base on which the injection device is mounted and the device frame, and the injection device is moved together with the slide base to bring the injection nozzle into contact with the mold.

[0030] The process of injecting the molten material into the molds 117, 118 is referred to as an "injection process". After the injection process, the process of cooling the molten material filled in the molds 117, 118 while maintaining a constant pressure is referred to as a "pressure holding process".

[0031] The temperature sensor 128 is disposed near the injection nozzle 126 of 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.

[0032] Once the dwell step is completed, the mold opening and ejection steps are carried out to remove the molded product.

[0033] The injection molding machine 100 can continuously form products by cyclically repeating a mold clamping process, an injection process, a pressure holding process, a plasticizing process, a mold opening process, and an ejection process.

[0034] The control device 140 is housed inside the base 121. The control device 140 typically includes a calculation device 141, a storage device 142, and a servo amplifier 143 for driving the servo motors 151 to 154. The calculation device 141 is a central processing unit (CPU) and / or a microcomputer. The storage device 142 includes a volatile or non-volatile memory such as a read only memory (ROM) and a random access memory (RAM), as well as a large-capacity storage device such as a hard disk drive (HDD) and a solid state drive (SSD). The control device 140 acquires detection values ​​of various sensors arranged in the injection molding machine 100 and controls each device of the injection molding machine 100 in an integrated manner.

[0035] The operation panel 130 is a device for an 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 acquire and display the status of the injection molding machine 100, and output a user operation signal from the input device to the control device 140. The operation panel 130 may be a touch panel in which the display device and the input device are integrated. The operation panel 130 may be attached to the bed 111 or base 121 of the injection molding machine 100, or may be disposed in a position independent of the injection molding machine 100.

[0036] [Control device configuration] Fig. 3 is a functional block diagram of the control device 140 of Fig. 2. The control device 140 includes a forming control unit 1401, a state management unit 1402, and a communication unit 1403.

[0037] The molding control unit 1401 includes the servo amplifier 143 described with reference to FIG.

[0038] The status management unit 1402 collects data indicating the operating status of the injection molding machine 100 and performs overall management of the injection molding machine 100. The status management unit 1402 acquires information such as command values ​​and current values ​​for each servo motor from the molding control unit 1401, and acquires detection values ​​from various sensors 160 arranged in the injection molding machine 100. The status management unit 1402 also acquires operation information from the operator inputted from the input device 131 of the operation panel 130.

[0039] The status 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 status management unit 1402 determines the presence or absence of 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.

[0040] The communication unit 1403 is an interface for communicating with the intraserver 20 and the cloud server 30 via the network 50. The status management unit 1402 uploads various types of information acquired from the injection molding machine 100 and information (logging data) indicating the operating status including detected abnormality information to the intraserver 20 and the cloud server 30 via the communication unit 1403.

[0041] The intra-server 20 and the cloud server 30 store in the storage device the logging data uploaded from the injection molding machine 100. As described in FIG. 1, the logging data stored in the cloud server 30 is appropriately transmitted to the external terminal device 40 in response to a request from the terminal device 40. This allows the user of the terminal device 40 to remotely monitor the status of the injection molding machine 100. Furthermore, the cloud server 30 may transmit an alarm to the terminal device 40 when an abnormality occurs in the injection molding machine 100.

[0042] [Data upload process to server] The process of uploading the logging data from the injection molding machine 100 to the server can be set, for example, so as to transmit the data periodically at a predetermined time interval from the start of the startup of the injection molding machine 100. The predetermined time interval is, for example, 30 seconds, 1 minute, 5 minutes, or 10 minutes.

[0043] In order to remotely monitor the status of the injection molding machine 100 as quickly as possible in real time, it is necessary to upload logging data at relatively short time intervals. However, since the injection molding machine 100 also executes a molding operation, which is the original function of the device, if the data transmission interval becomes short, there may be cases where the timing for uploading data arrives during the execution of a molding operation.

[0044] In the control device 140, the control program for performing the molding operation and the control program for uploading the logging data may share the same memory. In such a case, if the upload process is frequently performed, the time that the shared memory is occupied by the control program for uploading increases, and the molding operation may be delayed. This may cause a delay in the display of the display device 132 or make it impossible to set parameters using the input device 131. This may cause a cycle delay due to a delay in the execution time of each process, leading to a decrease in the operation rate of the device and causing quality defects.

[0045] Therefore, in this embodiment, when the upload timing arrives while the injection molding machine 100 is performing a cycle operation (during cycle operation), the upload process is stopped or delayed so that the molding operation is performed with priority. This may delay the update of information during monitoring on the external terminal device 40, but it is possible to suppress the effect on the molding control of the injection molding machine 100. Therefore, it is possible to prevent a decrease in the operating rate of the device and / or the occurrence of quality defects.

[0046] Fig. 4 is a time chart for explaining an example of the operation of the upload process to the server in the embodiment. The horizontal axis of Fig. 4 shows time, and the vertical axis shows the power supply state of the injection molding machine 100, the signal of the internal timer of the control device 140, the operating state of the cycle, and the execution state of the upload process.

[0047] When the power supply to the injection molding machine 100 is turned on at time t1, the control device 140 generates a transmission start pulse for starting an upload process to the server at each predetermined time interval T1.

[0048] When the cycle operation starts at time t2, the control device 140 turns on the "molding flag" which indicates that the cycle operation is in progress. If the upload timing arrives at time t3 during the cycle execution period, a start pulse for transmission is output, but since the molding flag is ON at time t3, the upload process is not executed (dashed line LN11).

[0049] After that, when the cycle operation ends at time t4 and the upload timing arrives at time t5 during the period until the start of the next cycle operation at time t6, the molding in progress flag is OFF, so the control device 140 executes the upload process to the server (solid line LN12). As a result, the logging data is transmitted to the intraserver 20 and the cloud server 30.

[0050] At times t7 and t10 when the upload timing occurs during cycle operation (i.e., while the molding flag is ON), the upload process is stopped as at time t3. Also, at time t12 when the upload timing occurs while the molding flag is OFF, the upload process is executed.

[0051] By performing such processing, it is possible to suppress a decrease in the operating rate and / or the occurrence of quality defects caused by a delay in the molding operation due to the upload process.

[0052] In the example of Fig. 4, the upload process is stopped when the upload timing arrives during the cycle operation, but if the start pulse from the timer and the molding in progress flag overlap, the upload process may be delayed until the cycle operation is completed. In this case, the upload process is started immediately after the cycle operation is completed. In this way, it is possible to prevent delays in updating data when monitoring externally due to the upload process being stopped repeatedly.

[0053] 5 is a flowchart of an upload process executed by the control device 140 of the injection molding machine 100. This flowchart is called from a main routine (not shown) and executed, for example, for each control cycle of the control device 140.

[0054] When the power supply of the injection molding machine 100 is turned on and the injection molding machine 100 is started, the control device 140 determines in step (hereinafter, step is abbreviated as "S") 100 whether or not a start pulse of upload timing is ON.

[0055] If the activation pulse is OFF (NO in S100), it is not the upload timing, so that control device 140 skips the subsequent processes and returns the process to the main routine.

[0056] On the other hand, if the start pulse is ON (YES in S100), the control device 140 determines that the timing for uploading logging data has arrived. Then, in S110, the control device 140 determines whether the molding in progress flag is OFF, that is, whether a cycle operation is not being performed.

[0057] If the molding in progress flag is OFF (YES in S110), the cycle operation is not in progress, so the control device 140 advances the process to S120 and uploads the collected logging data to the intra-server 20 and the cloud server 30 via the network 50.

[0058] On the other hand, if the forming in progress flag is ON (NO in S110), in order to prevent any effect on the forming operation, the control device 140 skips the subsequent steps and returns the process to the main routine.

[0059] When the upload process is delayed until the cycle is completed instead of being stopped, if the control device 140 determines that the molding flag is ON (NO in S110), the control device 140 advances the process to S115 shown by the dashed line in Fig. 5. In S115, the control device 140 monitors the transition of the molding flag from ON to OFF, and advances the process to S120 and executes the upload process when the molding flag becomes OFF.

[0060] By performing control according to the above-described process, it is possible to prevent the execution of the upload process during a molding operation by the injection molding machine 100. Therefore, it is possible to suppress the influence of information transmission to the server on molding control.

[0061] If the start condition for the molding operation is satisfied while the upload process is being performed, the upload process may be temporarily interrupted and the transmission of the remaining data may be resumed after the cycle operation is completed. Alternatively, if the transmission of 50% or more of the logging data has already been completed and the remaining data transmission time will be completed in a relatively short period of time, the upload process may be continued even if the start condition for the molding operation is satisfied, and the molding operation may be started after the transmission of the logging data is completed.

[0062] Moreover, the timer that determines the upload timing can be set in the input device 131 of the injection molding machine 100. In addition, the timer may be remotely set from any one of the intra-server 20, the cloud server 30, and / or the terminal device 40.

[0063] The "cloud server 30" in the embodiment corresponds to the "server" and the "external server" in the present disclosure.
