[0003] [Patent Document 1] JP 2011-167876 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, various peripheral devices that assist the injection molding machine are generally connected to the injection molding machine, and the setup support device for the injection molding machine described in Patent Document 1 can grasp the setup status of the setup items related to the injection molding machine during the setup work of the injection molding machine, but cannot grasp the setup status of the setup items related to the peripheral devices. In addition, the setup support device for the injection molding machine described in Patent Document 1 displays a setup screen during setup associated with the start of production of the injection molding machine, and can grasp the production of molded products based on a certain production plan, that is, the setup status of the setup items corresponding to a certain job, but cannot grasp the setup status of the setup items corresponding to the next job. Therefore, in the setup work of the injection molding machine, the operator cannot appropriately respond according to the setup status of the peripheral devices and the setup status of the next job, and there is a risk of a decrease in work efficiency. Therefore, there has been a demand for a setup support device that can inform the operator of the setup status of the peripheral devices and the setup status of the next job during the setup work of the injection molding machine. [Means for solving the problem]
[0005] A molding machine management system is a molding machine management system that manages an injection molding machine and peripheral equipment that assists the injection molding machine, and has a display unit that displays work items of the injection molding machine included in the setup work of the injection molding machine and work items of the peripheral equipment included in the setup work of the injection molding machine, and the display unit displays a first identification display that identifies a first job of the injection molding machine and a second job of the injection molding machine, and displays in a list format the progress of the work items of the injection molding machine corresponding to the first job, the progress of the work items of the peripheral equipment corresponding to the first job, the progress of the work items of the injection molding machine corresponding to the second job, and the progress of the work items of the peripheral equipment corresponding to the second job.

[0007] 1. Embodiment 1 A molding machine management system 1 according to a first embodiment will be described with reference to FIGS. 1 to 4. FIG. As shown in FIG. 1, the molding machine management system 1 includes an injection molding machine 2, a peripheral device 3 that assists the injection molding machine 2, and a management device 4. The injection molding machine 2 and the management device 4 are communicatively connected. The injection molding machine 2 and the peripheral device 3 are communicatively connected. As a result, the management device 4 and the peripheral device 3 are communicatively connected via the injection molding machine 2. In this embodiment, the management device 4 and the peripheral device 3 are communicatively connected via the injection molding machine 2, but the management device 4 and the peripheral device 3 may be communicatively connected without the injection molding machine 2. In this embodiment, the injection molding machine 2 and the peripheral device 3 are communicatively connected, but they may not be communicatively connected. In this embodiment, the injection molding machine 2 is communicatively connected to the management device 4, but there may be a plurality of injection molding machines 2 communicatively connected to the management device 4.
[0008] The injection molding machine 2 includes a molding control unit 21, a hopper 22 which is a material storage unit, an injection unit 23, a mold 26 having a cavity, and a mold clamping unit 27 which clamps the mold 26.
[0009] The hopper 22 stores the material in a state such as pellets or powder, and supplies the material to the injection unit 23. In this embodiment, the hopper 22 includes a heating unit (not shown). The heating unit (not shown) included in the hopper 22 is used to suppress moisture absorption of the material stored in the hopper 22 and to keep the material stored in the hopper 22 dry.
[0010] The injection unit 23 includes an impeller (not shown) having a shape such as a vortex type or a screw type, a heating unit (not shown), and a manifold 24. The impeller and heating unit of the injection unit 23 plasticize the material supplied from the hopper 22 to the injection unit 23. The manifold 24 is a metal block having a flow path (not shown) formed therein, and sends the material plasticized by the impeller and heating unit to the mold 26 through the flow path. In this embodiment, the manifold 24 includes a heating unit (not shown) and a hot runner nozzle (not shown). The injection unit 23 plasticizes the material supplied from the hopper 22, and injects a predetermined amount of the plasticized material into the mold 26 through the manifold 24.
[0011] The mold 26 has a cavity which is a space into which the material injected from the injection section 23 is filled.
[0012] The mold clamping section 27 clamps the mold 26 so that the mold 26 does not open due to the filling pressure when the material injected from the injection section 23 fills the cavity.
[0013] The molding control unit 21 has a function of controlling the overall operation of the injection molding machine 2 to execute injection molding, and a function of communicating with the peripheral device 3 and the management device 4 via an interface (not shown).
[0014] In accordance with the molding program, the molding control unit 21 controls the injection unit 23 to inject the material supplied from the hopper 22 into the mold 26, and controls the mold clamping unit 27 to clamp the mold 26, thereby molding a molded product having a shape that corresponds to the shape of the cavity of the mold 26.
[0015] The molding program is a program for performing one injection molding in the injection molding machine 2, and specifies molding conditions such as the timing for changing control values for the injection unit 23, the mold clamping unit 27, etc., and the magnitude of the control values.
[0016] The molding control unit 21 executes the molding program a number of times corresponding to the planned production number preset in the production plan of the molded products to be produced by the injection molding machine 2, and performs injection molding to mold the planned number of molded products. In this embodiment, one injection molding cycle is called a shot, and the unit time from the start to the end of one injection molding cycle is called cycle time (sec / shot). Also, executing the molding program a number of times corresponding to the planned production number and molding the planned number of molded products is called a job.
[0017] The molding control unit 21 also has a function of acquiring various time series data related to injection molding using various sensors (not shown) provided in the injection molding machine 2. Examples of the various sensors include a weight sensor that detects the weight of the material stored in the hopper 22, a pressure sensor that detects the pressure of the gas in the injection unit 23 and the material in the mold 26, and a temperature sensor that detects the temperature of the injection unit 23, the mold 26, etc. The time series data is data obtained by continuously or intermittently acquiring the detection values of various sensors during a predetermined period. Since the acquisition of such various time series data is performed in any injection molding machine, a detailed description will be omitted.
[0018] Various time series data related to injection molding acquired by the molding control unit 21 is transmitted from the molding control unit 21 to the management device 4.
[0019] The peripheral equipment 3 is equipment that supports the injection molding machine 2. Examples of the peripheral equipment 3 include a dryer, a temperature regulator, an inspection device, a processing machine, and a conveying device.
[0020] The dryer is used to dehumidify and dry the material before supplying it to the injection molding machine 2. The temperature regulator is used to adjust the temperature of the mold 26. The inspection device is, for example, an image inspection device, and is used to determine the presence or absence of abnormalities in the appearance of each molded product by visual inspection using images of the molded product. The processing machine is used to remove burrs and the like from the molded product. The transport device is, for example, a robot arm, and is used to remove the molded product from the mold 26 and transport the molded product to the processing machine, etc.
[0021] Such peripheral equipment 3 is provided with various sensors (not shown) for detecting the operating conditions of the peripheral equipment 3. For example, a dryer or a temperature controller, which is the peripheral equipment 3, is provided with a temperature sensor for detecting the temperature inside the dryer or the temperature of the heat medium of the temperature controller. Time series data relating to the operating conditions of the peripheral equipment 3 acquired by the various sensors provided in the peripheral equipment 3 is transmitted to the molding control unit 21 of the injection molding machine 2 via an interface (not shown). Then, the time series data relating to the operating conditions of the peripheral equipment 3 is transmitted from the molding control unit 21 to the management device 4.
[0022] In this embodiment, the peripheral device 3 and the injection molding machine 2 are configured as independent devices, but the peripheral device 3 and the injection molding machine 2 may be configured as an integrated device.
[0023] Furthermore, the peripheral device 3 may be, for example, an information processing device having a database constructed by accumulating molding conditions for molded items previously produced by the injection molding machine 2. Using the information processing device having a database accumulating molding conditions for each molded item, an operator can read molding conditions from the database according to the molded item to be produced, and set the molding conditions and generate a molding program. Furthermore, the information processing device as the peripheral device 3 can transmit the molding conditions read from the database and the molding program generated based on the molding conditions to the injection molding machine 2 and the management device 4.
[0024] In this embodiment, the information processing device as the peripheral device 3, the injection molding machine 2, and the management device 4 are each configured as independent devices, but the information processing device as the peripheral device 3 and the injection molding machine 2 or the management device 4 may be configured as an integrated device.
[0025] The management device 4 includes a control unit 41, a storage unit 42, an operation unit 43, and a display unit 44. The management device 4 may be, for example, an information processing device such as a computer. In this embodiment, the management device 4 is provided independently from the injection molding machine 2, but it is not necessary to provide it independently from the injection molding machine 2, and the management device 4 and the injection molding machine 2 may be configured as one unit. For example, the molding machine management system 1 can be realized by using the molding control unit 21 originally provided in the injection molding machine 2, and the display unit (not shown), operation unit, and storage unit originally provided in the injection molding machine 2 as the management device 4.
[0026] The control unit 41 has a function of receiving various time series data related to injection molding transmitted from the injection molding machine 2 and various time series data related to the operating status of the peripheral equipment 3 transmitted from the peripheral equipment 3, and storing the same in the memory unit 42, a function of controlling the display unit 44 by starting a setup support program previously stored in the memory unit 42, and displaying a management screen, etc. for supporting the setup work of the injection molding machine 2 on the display unit 44, and a function of calculating the progress status of each of the various work items included in the setup work of the injection molding machine 2.
[0027] The control unit 41 may be implemented using an integrated circuit such as a central processing unit (CPU) or a micro processing unit (MPU).
[0028] The storage unit 42 stores various time series data related to injection molding, various time series data related to the operating conditions of the peripheral devices 3, a setup support program for displaying on the display unit 44 a management screen or the like for supporting the setup work of the injection molding machine 2, and data used to calculate the progress status of each of the various work items included in the setup work of the injection molding machine 2. The data used to calculate the progress status of each of the various work items included in the setup work of the injection molding machine 2 is, for example, the standard operation time of each of the various work items.
[0029] As the storage unit 42, for example, a volatile memory such as a random access memory (RAM), a non-volatile memory such as a read only memory (ROM), or a removable external storage device can be used.
[0030] The operation unit 43 transmits an operation signal to the control unit 41 based on an input operation, a selection operation, a screen transition operation, etc., performed by the operator. The control unit 41 performs various processes such as changing the display content of the display unit 44 based on the operation signal from the operation unit 43.
[0031] The operation unit 43 may be, for example, a keyboard, a mouse, a touch panel, or the like.
[0032] Under the control of the control unit 41, the display unit 44 displays various screens, such as a management screen for supporting the setup work of the injection molding machine 2, and an input screen for the operator to input the operating status of the injection molding machine 2 and each of the peripheral devices 3.
[0033] For example, a liquid crystal display can be used as the display unit 44. The display unit 44 and the operation unit 43 may be integrated together, such as a touch panel display.
[0034] Next, the management screen W1 displayed by the display unit 44 will be described with reference to FIG. As shown in Fig. 2, the display unit 44 displays a management screen W1 for supporting the setup work of the injection molding machine 2. By viewing the management screen W1, an operator can grasp the progress of the setup work of the injection molding machine 2. Note that various character strings and numerical values in Fig. 2 may be displayed differently from the actual character strings and numerical values in order to easily explain the present invention.
[0035] In the present invention, "setup" refers to work other than molding of a molded product among the work that occurs in order to mold a molded product, and is a concept that includes pre-setup performed before molding of a molded product and post-setup performed after molding of a molded product. Furthermore, "setup" includes work performed by an operator on peripheral equipment 3, in addition to work performed on injection molding machine 2. Work performed by an operator on peripheral equipment 3 includes work that is performed by operating peripheral equipment 3, such as material drying, which will be described later.
[0036] The management screen W1 includes a table T1 for displaying in a list format various work items included in the setup work 6 of the injection molding machine 2 and the progress status of each of the work items, a molding machine selection field F1 for selecting the injection molding machine 2 that the worker manages, and a setup button B1, an inspection button B2, and a job information button B3 which are buttons for switching the screen displayed by the display unit 44. The various work items included in the setup work 6 of the injection molding machine 2 include an injection molding machine 2 work item 6a that the worker performs on the injection molding machine 2, and a peripheral device 3 work item 6b that the worker performs on the peripheral device 3.
[0037] When the operator selects the setup button B1, the display unit 44 displays a management screen W1 that displays the progress of the setup work 6 of the injection molding machine 2. Also, as described below, when the operator selects the inspection button B2 or the job information button B3, the display unit 44 displays a screen that displays the progress of the inspection work or a screen that displays job information, depending on the button selected by the operator.
[0038] In this embodiment, the worker operates the operation unit 43 of the management device 4 to input the name of the injection molding machine 2 that the worker manages into the molding machine selection field F1. The display unit 44 displays, as a table T1, the progress status of the work items 6a and 6b included in the setup work 6 for the injection molding machine 2 input into the molding machine selection field F1.
[0039] Next, Table T1 will be specifically described. Table T1 is an example of displaying in list form the work items 6a for the injection molding machine 2, the work items 6b for the peripheral equipment 3, the progress of the work items 6a for the injection molding machine 2, and the progress of the work items 6b for the peripheral equipment 3.
[0040] In this embodiment, a first identification display 5 for identifying the first job of the injection molding machine 2 and the second job of the injection molding machine 2 is displayed in a row located at the top of the table T1. A work item 6a of the injection molding machine 2 included in the setup work 6 of the injection molding machine 2 and a work item 6b of the peripheral device 3 included in the setup work 6 of the injection molding machine 2 are displayed in a column located on the front side of the table T1. In the body of the table T1, a progress status is displayed in a cell where a row and a column intersect. In addition, a second identification display 10 for identifying the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3 are displayed in a column adjacent to the front side opposite to the body of the table T1. The second identification display 10 will be described later.
[0041] In addition, the work item 6a for the injection molding machine 2 and the work item 6b for the peripheral device 3 may be displayed in the row at the top of table T1, and the first identification display 5 may be displayed in the column on the front side of table T1.
[0042] The first identification indicator 5 displayed in the row located at the top of table T1 will be described. The first identification display 5 for distinguishing between the first job of the injection molding machine 2 and the second job of the injection molding machine 2 is, for example, the name of the job performed by the injection molding machine 2. In this embodiment, the names of the jobs performed by the injection molding machine 2 are "Job 1", "Job 2", and "Job 3" in the order in which the injection molding machine 2 performs the jobs. Job 1 is a job in which the setup work 6 is being performed, Job 2 is a job in which the production of a molded product is planned after Job 1, and Job 3 is a job in which the production of a molded product is planned after Job 2. In the row located at the top of the table T1, Job 1, Job 2, and Job 3 as the first identification display 5 are arranged in the order in which the injection molding machine 2 performs the jobs, that is, in chronological order. In this embodiment, three jobs, Job 1, Job 2, and Job 3, are displayed as the first identification display 5, but the number of first identification displays 5 may be two or four or more. Furthermore, the first identification mark 5 is not limited to the name of the job, but may be, for example, the molded item produced in each job.
[0043] The work items 6a and 6b included in the setup work 6 for the injection molding machine 2 displayed in the columns on the front side of table T1 will be described. In the columns on the front side of Table T1, the work items 6a for the injection molding machine 2 and the work items 6b for the peripheral equipment 3, namely, “material drying”, “installation of temperature regulator”, “manifold heating”, “purging for resin change”, “hopper heating”, “manifold cooling”, “reading of molding conditions”, “pre-production purge”, “mold installation”, “mold heating”, and “exhaust shot”, are arranged in the order in which the worker will perform the setup work 6, i.e., in chronological order.
[0044] The material drying is an operation of drying the material of the molded product molded by the injection molding machine 2 with a dryer as the peripheral device 3. The temperature regulator installation is an operation of installing a temperature regulator as the peripheral device 3 for adjusting the temperature of the mold 26 near the injection molding machine 2 and adjusting the temperature of the heat medium of the temperature regulator. The manifold temperature increase is an operation of increasing the temperature of the manifold 24 of the injection molding machine 2 before the resin change purge. The resin change purge is an operation of cleaning the inside of the injection molding machine 2, such as the impeller and the flow paths in the manifold 24, using a purge material that is a cleaning agent for the molding machine. The hopper temperature increase is an operation of increasing the temperature of the heating section provided in the hopper 22 of the injection molding machine 2 in order to dry the material stored in the hopper 22. The manifold temperature decrease is an operation of decreasing the temperature of the manifold 24 before the mold installation, thereby reducing the thermal expansion of the manifold 24. The loading of molding conditions is an operation of loading molding conditions for the molded product to be produced by the injection molding machine 2 from a database provided in an information processing device as a peripheral device 3. The pre-production purging is an operation of discharging from the injection molding machine 2 any purging material remaining inside the injection molding machine 2 or material that has been thermally deteriorated by remaining inside the injection molding machine 2, and replacing the inside of the injection molding machine 2 with new material. The attachment of mold is an operation of attaching the mold 26 to the injection molding machine 2. The heating of mold is an operation of connecting piping for circulating the heat medium of the temperature regulator to the mold 26, and heating the mold 26 before molding the molded product. The throw-away casting is an operation of molding samples of molded products that will not be incorporated as good products and will be discarded until the quality of the molded products stabilizes.
[0045] In this embodiment, the work items 6a and 6b displayed in the columns on the front side of table T1, such as material drying, temperature regulator installation, manifold temperature increase, resin change purge, hopper temperature increase, manifold temperature decrease, molding condition reading, pre-production purge, mold installation, mold temperature increase, and trial shot, are examples of work included in the setup work 6 of the injection molding machine 2. As the work items 6a and 6b, some of these work may not be displayed, and work included in the setup work 6 of the injection molding machine 2 other than these work may be displayed in table T1. In this embodiment, the work items 6a and 6b displayed in the columns on the front side of table T1 are work corresponding to pre-setup among the setup work 6, but may include work corresponding to post-setup.
[0046] The progress displayed in a cell at the intersection of a row and a column in the body of table T1 will be described below. For example, among the cells displayed on the body of table T1, cell 7a where the column for job 1 as the first job in first identification display 5 intersects with the row for material drying in work items 6a and 6b displays the progress status of material drying corresponding to job 1. Since material drying corresponding to job 1 is a task in progress, cell 7a displays the progress rate of material drying corresponding to job 1 and the scheduled completion time of material drying corresponding to job 1.
[0047] Similarly, cell 7b displays the progress of temperature regulator installation corresponding to job 1, and cell 7c displays the progress of manifold temperature lowering corresponding to job 1. Because temperature regulator installation corresponding to job 1 and manifold temperature lowering corresponding to job 1 are tasks currently being performed, cells 7b and 7c display the progress rate and estimated completion time of each task.
[0048] Among the cells displayed in the body of table T1, cell 7d displays the progress of the hopper heating corresponding to job 1. Since the hopper heating corresponding to job 1 is a task that has been completed, a check mark is displayed as a symbol indicating completion.
[0049] Of the cells displayed in the body of table T1, cell 7e displays the progress of the throw-away printing corresponding to job 1. Because the throw-away printing work corresponding to job 1 is work that has not been performed, a hyphen is displayed as a symbol indicating that it has not been performed. Similarly, cell 7f displays the progress of the temperature regulator installation corresponding to job 2, the second job, and cell 7g displays the progress of the resin change purging corresponding to job 2. Because the temperature regulator installation corresponding to job 2 and the resin change purging corresponding to job 2 are work that has not been performed, cells 7f and 7g display a hyphen as a symbol indicating that it has not been performed.
[0050] Among the cells displayed on the front surface of table T1, cell 7h is a cell indicating material drying corresponding to job 3. In this embodiment, material drying corresponding to job 3 is an unnecessary task. To indicate that material drying corresponding to job 3 is an unnecessary task, the background of cell 7h is shaded with diagonal lines slanting upward to the right, and the display form is different from that of the other cells. Job 3 corresponds to the second job when job 2 is the first job.
[0051] In this way, by displaying table T1 on the management screen W1 by the display unit 44, the progress status of the work item 6a of the injection molding machine 2 corresponding to job 1 as the first job, the progress status of the work item 6b of the peripheral device 3 corresponding to job 1, the progress status of the work item 6a of the injection molding machine 2 corresponding to job 2 as the second job, and the progress status of the work item 6b of the peripheral device 3 corresponding to job 2 can be displayed in a list format. This makes it possible to provide a molding machine management system 1 that can inform the worker of not only the progress status of the work item 6a of the injection molding machine 2 but also the progress status of the work item 6b of the peripheral device 3 in the setup work 6 of the injection molding machine 2. Also, it is possible to provide a molding machine management system 1 that can inform the worker of not only the setup work 6 corresponding to job 1 but also the setup work 6 of job 2 in which production of a molded product is planned next to job 1. This molding machine management system 1 allows workers to respond appropriately to the setup work 6 of the injection molding machine 2 depending on the setup status of the peripheral equipment 3 and the progress of the setup work 6 for the next job, thereby improving work efficiency.
[0052] In this embodiment, the progress status of the work item 6a of the injection molding machine 2 and the progress status of the work item 6b of the peripheral device 3 are displayed using numerical values indicating the progress rate and symbols such as check marks and hyphens, but the display of the progress status is not limited to these. For example, the progress status may be displayed using character strings such as "not yet performed", "in progress", and "completed".
[0053] In this embodiment, for the work items 6a of the injection molding machine 2, the progress rate and the scheduled completion time are displayed as the progress status for the work being performed, but it is also possible to display either one of them. Similarly, in this embodiment, for the work items 6b of the peripheral device 3, the progress rate and the scheduled completion time are displayed as the progress status for the work being performed, but it is also possible to display either one of them.
[0054] In this embodiment, the progress rate of the work item 6a of the injection molding machine 2 and the progress rate of the work item 6b of the peripheral device 3 are displayed as numerical values, but may be displayed as graphs such as bar graphs or pie charts.
[0055] The progress rate of the work item 6a of the injection molding machine 2 and the progress rate of the work item 6b of the peripheral device 3 can be calculated, for example, by (time elapsed from the start of the work items 6a and 6b to the present) / (standard work time of the work items 6a and 6b). The time elapsed from the start of the work items 6a and 6b to the present can be obtained, for example, by the control unit 41 of the management device 4 detecting that the worker has started inputting information related to the work items 6a and 6b using an operation unit (not shown) provided in the injection molding machine 2 and the peripheral device 3, and the control unit 41 measuring the time from the time the worker started inputting information related to the work items 6a and 6b to the present.
[0056] In addition, the progress rate of the work item 6a of the injection molding machine 2 and the progress rate of the work item 6b of the peripheral equipment 3 can also be calculated, for example, based on detection values detected by various sensors (not shown) equipped on the injection molding machine 2 and the peripheral equipment 3.
[0057] Of the work items 6a and 6b, in the hopper temperature increase, manifold temperature increase, manifold temperature decrease, and mold temperature increase, the progress rate can be calculated by detecting the temperatures of the hopper 22, manifold 24, and mold 26 in each of the work items 6a and 6b using a sensor (not shown). For example, in the hopper temperature increase, the progress rate of the hopper temperature increase can be calculated by (current temperature of the hopper 22 - temperature of the hopper 22 when the hopper temperature increase started) / (set temperature of the hopper 22 in the hopper temperature increase - temperature of the hopper 22 when the hopper temperature increase started). Similarly, in the manifold temperature increase, manifold temperature decrease, and mold temperature increase, the progress rate of each work can be calculated from the current temperatures of the manifold 24 and mold 26, the set temperatures set in advance by the operator for each work, and the temperatures of the manifold 24 and mold 26 when each work started.
[0058] Of the work items 6a and 6b, in the resin change purging and pre-production purging, the progress rate can be calculated by detecting the weight of the purging material or the material of the molded product discharged from the injection unit 23 of the injection molding machine 2 in each of the work items 6a and 6b by a sensor (not shown). For example, the progress rate can be calculated by (weight of the purging material or the material of the molded product discharged from the injection unit 23) / (a set value set in advance by the operator as the weight of the purging material or the material of the molded product discharged from the injection unit 23).
[0059] Of the work items 6a and 6b, in the trial shot, the gas pressure in the ejection section 23 is detected by a sensor (not shown) installed in the ejection section 23, and the progress rate can be calculated based on the magnitude of variation in the gas pressure in the ejection section 23.
[0060] Next, the second identification mark 10 for identifying the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3 will be described.
[0061] The second identification display 10 is provided to clearly indicate to the worker whether the work item 6a for the injection molding machine 2 and the work item 6b for the peripheral device 3 displayed on the front side of the table T1 are work for the injection molding machine 2 or work for the peripheral device 3. In this embodiment, the second identification display 10 is the type of device on which the worker is to work in the work items 6a and 6b. Specifically, the display unit 44 displays two types as the second identification display 10: "molding machine" indicating the injection molding machine 2 and "peripheral device" indicating the peripheral device 3.
[0062] By displaying the second identification mark 10 on the table T1 by the display unit 44, the worker can easily understand whether the work items 6a and 6b displayed on the front side of the table T1 are work for the injection molding machine 2 or work for the peripheral device 3, respectively. This improves the worker's work efficiency. The second identification mark 10 may be a mark other than the two types of "molding machine" and "peripheral device". For example, in the injection molding machine 2, the specific names of the parts of the injection molding machine 2 that the worker works on, such as the hopper 22, the injection unit 23, and the mold clamping unit 27, may be the second identification mark 10, and in the peripheral device 3, the specific names of the peripheral device 3 that the worker works on, such as the dryer and the temperature controller, may be the second identification mark 10.
[0063] In addition, in this embodiment, as described above, when the worker inputs the name of the injection molding machine 2 in the molding machine selection field F1 on the management screen W1, the display unit 44 displays the progress status of the work items 6a and 6b included in the setup work 6 of the injection molding machine 2 input in the molding machine selection field F1 as a table T1. In other words, when the management device 4 is connected to a plurality of injection molding machines 2 so as to be able to communicate with each other, the worker can change the name of the injection molding machine 2 input in the molding machine selection field F1 to display the progress status of the setup work 6 for each of the plurality of injection molding machines 2 on the management screen W1. This allows the worker to grasp the progress status of the setup work 6 for each of the plurality of injection molding machines 2. The worker can determine the priority order of the setup work 6 based on the progress status, thereby improving work efficiency.
[0064] In this embodiment, the management screen W1 displays the progress status of the setup work 6 for one injection molding machine 2 as table T1, but the progress status of the setup work 6 for each of a plurality of injection molding machines 2 may be simultaneously displayed on the management screen W1. By simultaneously displaying the progress status of the setup work 6 for each of the plurality of injection molding machines 2 on the management screen W1, the worker can easily grasp the progress status of the setup work 6 for each of the plurality of injection molding machines 2.
[0065] Next, the inspection screen W2 displayed on the display unit 44 when the operator selects the inspection button B2 will be described with reference to FIG.
[0066] As shown in Fig. 3, when an operator selects an inspection button B2, the display unit 44 displays an inspection screen W2 for displaying the progress of the inspection work of the injection molding machine 2 and the progress of the inspection work of the peripheral device 3. The inspection screen W2 includes a table T2 for displaying the progress of the inspection work of the injection molding machine 2 and the progress of the inspection work of the peripheral device 3 in a list format, a molding machine selection field F1 for selecting the injection molding machine 2, and a setup button B1, an inspection button B2, and a job information button B3, which are buttons for switching the screen displayed by the display unit 44. Note that various character strings and numerical values in Fig. 3 may be displayed differently from the actual character strings and numerical values in order to easily explain the present invention.
[0067] Table T2 for displaying in a list form the progress status of the inspection work of the injection molding machine 2 and the progress status of the inspection work of the peripheral device 3 will be described. In this embodiment, a first identification display 5 for distinguishing between a first job of the injection molding machine 2 and a second job of the injection molding machine 2 is displayed in a row located at the top of the table T2. A name 11 of the equipment to be inspected is displayed in a column located on the front side of table T2. A type 12 of inspection work is displayed in an adjacent column on the side of table T2 opposite the front body. In the front body of table T2, the progress status is displayed in a cell where a row and a column intersect.
[0068] The first identification display 5 displayed in the row located at the top of table T2 is the same as that in table T1 of the management screen W1 shown in FIG. 2, and therefore a description thereof will be omitted.
[0069] The names 11 of the devices to be inspected, which are displayed in the columns on the front side of Table T2, will now be described. In this embodiment, in a column on the front side of table T2, a "molding machine" as the injection molding machine 2 and an "image inspection device" as an example of peripheral device 3 are displayed in this order as the name 11 of the device to be inspected. In this embodiment, table T2 displays the image inspection device as an example of peripheral device 3, but peripheral devices 3 other than the image inspection device, such as a dryer or a temperature controller, may be included in table T2 as devices to be inspected.
[0070] The following describes the type of inspection work 12 displayed in the adjacent column on the side of table T2 opposite the surface body. In this embodiment, in a column adjacent to the front side opposite to the front body of table T2, "daily inspection" is displayed as the inspection work type 12. Note that "daily inspection" is an example of the inspection work type 12, and inspection work other than daily inspection, such as annual periodic inspection, may be included in the inspection work type 12.
[0071] The progress of the inspection work displayed in the cell where the row and column intersect in the body of table T2 will be described. For example, in table T2, cell 13a where the column corresponding to job 1 intersects with the row corresponding to the image inspection device displays the progress status of the daily inspection of the image inspection device corresponding to job 1. Since the daily inspection of the image inspection device corresponding to job 1 is an inspection task that is being performed, cell 13a displays the progress rate and expected completion time of the daily inspection of the image inspection device corresponding to job 1.
[0072] Cell 13b displays the progress of the daily inspection of the injection molding machine 2 corresponding to job 1. Since the daily inspection of the injection molding machine 2 corresponding to job 1 is an inspection task that has been completed, a check mark is displayed as a symbol indicating that it has been completed. Cell 13c displays the progress of the daily inspection of the image inspection device corresponding to job 2. Since the daily inspection of the image inspection device corresponding to job 2 is an inspection task that has not been completed, a hyphen is displayed as a symbol indicating that it has not been completed.
[0073] By displaying table T2 on inspection screen W2 by display unit 44 in this way, the worker can grasp the progress of the inspection work of the injection molding machine 2 and the progress of the inspection work of the peripheral device 3. This allows the worker to respond appropriately according to the progress of the inspection work of each of the injection molding machine 2 and the peripheral device 3, thereby improving work efficiency.
[0074] In this embodiment, table T2 displays the progress status of the inspection work of the injection molding machine 2 and the progress status of the inspection work of the peripheral equipment 3, but it is also possible to display only one of the progress status of the inspection work of the injection molding machine 2 and the progress status of the inspection work of the peripheral equipment 3.
[0075] In this embodiment, the progress status of the inspection work of the injection molding machine 2 and the progress status of the inspection work of the peripheral device 3 are displayed using numerical values indicating the progress rate and symbols such as check marks and hyphens, but the display of the progress status is not limited to these. For example, the progress status may be displayed in stages using character strings such as "not yet performed", "in progress", and "completed".
[0076] In this embodiment, as the progress status of the inspection work of the injection molding machine 2 and the inspection work of an image inspection device as an example of peripheral equipment 3, if the work is being carried out, the progress rate and the estimated completion time are displayed, but it is also possible to display only one of them.
[0077] In this embodiment, the progress rate of the inspection work of the injection molding machine 2 and the progress rate of the inspection work of the peripheral device 3 are displayed as numerical values, but may be displayed as graphs such as bar graphs or pie charts.
[0078] Furthermore, the progress rate of the inspection work of the injection molding machine 2 and the peripheral equipment 3 can be calculated in the same way as the progress rate of the work item 6a of the injection molding machine 2 and the progress rate of the work item 6b of the peripheral equipment 3. For example, it can be calculated by (time elapsed from the start of the inspection work to the present) / (standard work time for the inspection work). The time elapsed from the start of the inspection work to the present can be obtained, for example, by the control unit 41 of the management device 4 detecting that the worker has started inputting information related to the inspection work using an operation unit (not shown) provided on the injection molding machine 2 and the peripheral equipment 3, and the control unit 41 measuring the time from the time the worker started inputting information related to the inspection work to the present.
[0079] Next, the job information screen W3 displayed on the display unit 44 when the worker selects the job information button B3 will be described with reference to FIG.
[0080] As shown in Fig. 4, when the operator selects the job information button B3, the display unit 44 displays a job information screen W3 for displaying information on jobs of the injection molding machine 2. The job information screen W3 includes a table T3 for displaying information on jobs of the injection molding machine 2 in a list format, a molding machine selection field F1 for selecting the injection molding machine 2, and a setup button B1, an inspection button B2, and a job information button B3, which are buttons for switching the screen displayed by the display unit 44. Note that various character strings and numerical values in Fig. 4 may be displayed differently from the actual character strings and numerical values in order to easily explain the present invention.
[0081] Table T3 for displaying information on jobs of the injection molding machine 2 in a list format will be described. In this embodiment, a first identification display 5 for distinguishing between a first job of the injection molding machine 2 and a second job of the injection molding machine 2 is displayed in a row located at the top of table T3. Job information categories 15 are displayed in columns located on the front side of table T3. In the body of table T3, job information corresponding to job information category 15 is displayed in cells where rows and columns intersect.
[0082] The first identification display 5 displayed in the row located at the top of table T3 is the same as that in table T1 of the management screen W1 shown in FIG. 2, and therefore a description thereof will be omitted.
[0083] The job information section 15 displayed in the columns on the front side of table T3 will be described. In this embodiment, the columns on the front side of Table T3 are arranged in the following order as job information categories 15: “Molding item,” “Planned production quantity,” “Item of material 1,” “Required quantity of material 1,” “Item of material 2,” and “Required quantity of material 2.”
[0084] In the columns on the front side of table T3, the molding item is an item related to the molding item of the molded product planned to be produced in each job, such as the name and part number of the molded product. The planned production quantity is an item related to the planned production quantity of the molded product planned to be produced in each job. The item of material 1 and the item of material 2 are items related to the materials used to produce the molded product planned to be produced in each job, such as the name and part number of the material. The required quantity of material 1 and the required quantity of material 2 are items related to the quantity of material required to produce the molded product planned to be produced in each job. In this embodiment, two types of material, material 1 and material 2, are displayed in table T3 as materials required to produce the molded product planned to be produced, but one type or three or more types of material may be displayed in table T3. In addition, the molding item, planned production quantity, item of material 1, required quantity of material 1, item of material 2, and required quantity of material 2 are examples of job information category 15, and as job information category 15, for example, the scheduled production start time and scheduled production end time may be displayed in table T3.
[0085] The job information displayed in the cell where the row and column intersect in the body of table T3 will be described. For example, in table T3, cell 16a, where the column corresponding to job 1 intersects with the row corresponding to the molding item, displays "Part A" as the molding item corresponding to job 1, and cell 16b, where the column corresponding to job 1 intersects with the row corresponding to the planned production quantity, displays "5000" as the planned production quantity corresponding to job 1, indicating that job 1 is a job to produce 5000 pieces of Part A.
[0086] Also, for example, in table T3, cell 16c where the column corresponding to job 2 intersects with the row corresponding to material 1 item displays “material C” as material 1 for the molded product corresponding to job 1, and cell 16d where the column corresponding to job 2 intersects with the row corresponding to material 2 item displays “material D” as material 2 for the molded product corresponding to job 2. It can be seen that job 2 uses materials C and D as materials for the molded product to be produced in job 2.
[0087] In this way, the display unit 44 displays the table T3 on the job information screen W3, so that the worker can grasp the job information of the injection molding machine 2. This allows the worker to take appropriate action according to the job information of the injection molding machine 2, thereby improving work efficiency.
[0088] In this embodiment, when the operator selects the setup button B1, the inspection button B2, and the job information button B3, the display unit 44 switches between displaying the management screen W1 including table T1, the inspection screen W2 including table T2, and the job information screen W3 including table T3. However, the display unit 44 may display tables T1 and T2, or tables T1 and T3 on the same screen.
[0089] As described above, according to this embodiment, the following effects can be obtained. The molding machine management system 1 of this embodiment is equipped with a display unit 44 that displays work items 6a of the injection molding machine 2 included in the setup work 6 of the injection molding machine 2 and work items 6b of the peripheral equipment 3 included in the setup work 6 of the injection molding machine 2, and the display unit 44 displays a first identification display 5 that identifies job 1 as the first job of the injection molding machine 2 and job 2 as the second job of the injection molding machine 2, and can display in list format as table T1 the progress status of the work item 6a of the injection molding machine 2 corresponding to job 1, the progress status of the work item 6b of the peripheral equipment 3 corresponding to job 1, the progress status of the work item 6a of the injection molding machine 2 corresponding to job 2, and the progress status of the work item 6b of the peripheral equipment 3 corresponding to job 2. This makes it possible to provide a molding machine management system 1 that can inform an operator of the progress status of the work items 6b of the peripheral device 3 as well as the progress status of the work items 6b of the peripheral device 3. It is also possible to provide a molding machine management system 1 that can inform an operator of the setup work 6 of job 2 as a second job as well as the setup work 6 of job 1 as a first job. This molding machine management system 1 allows an operator to appropriately respond to the setup work 6 of the injection molding machine 2 according to the setup state of the peripheral device 3 and the progress status of the setup work 6 of the next job, thereby improving work efficiency.
[0090] 2. Embodiment 2 Next, the management screen W1a displayed by the display unit 44 of the molding machine management system 1 according to the second embodiment will be described with reference to FIG. 5. The same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. The management screen W1a according to the second embodiment includes a table T1a. The second embodiment is similar to the first embodiment except that the table T1a has a second identification display 10a for identifying the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3, which is different from that in the first embodiment. In the second embodiment, the display unit 44 displays the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3 in different display forms as the second identification display 10a.
[0091] As shown in FIG. 5, in the second embodiment, there is no adjacent column on the side of the table T1a opposite the front body, and a second identification display 10a for identifying the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3 is realized by making a part of the table T1a into a different display form.
[0092] In this embodiment, the display unit 44 displays, in the columns located on the front side of table T1a, a work item 6a of the injection molding machine 2 included in the setup work 6 of the injection molding machine 2 and a work item 6b of the peripheral equipment 3 included in the setup work 6 of the injection molding machine 2, and in the cell corresponding to the work item 6a of the injection molding machine 2, displays the cell background in unshaded white as the second identification display 10a, and in the cell corresponding to the work item 6b of the peripheral equipment 3, displays the cell background in a light shaded color as the second identification display 10a.
[0093] For example, in the columns located on the front side of table T1a, the backgrounds of cell 60a displaying material drying, which is a work item 6b of the peripheral device 3, cell 60b displaying temperature regulator installation, and cell 60c displaying molding condition reading are displayed with light shading. On the other hand, in the columns located on the front side of table T1a, the backgrounds of cells other than cells 60a, 60b, and 60c, i.e., cell 60d displaying manifold temperature reduction, cell 60e displaying trial shot, which are work items 6a of the injection molding machine 2, are displayed in white without shading.
[0094] In other words, in the columns located on the front side of table T1a, the cells corresponding to the work items 6a of the injection molding machine 2 and the cells corresponding to the work items 6b of the peripheral equipment 3 are displayed with different shading, which is a different display format, depending on whether the work items 6a, 6b displayed in each cell are the work items 6a of the injection molding machine 2 or the work items 6b of the peripheral equipment 3.
[0095] The different display forms are not limited to changing the shading of the cells, but may be any display form such as changing the background color of the cells, the borders of the cells, changing the color or font of the letters or numbers displayed in the cells, adding symbols such as icons, etc. In the present embodiment, the display form of the cells in the columns located on the front side of the table T1a is changed as the second identification mark 10a, but it is not limited to the cells in the columns located on the front side of the table T1a, and for example, the display form of the row including the cells in the columns located on the front side of the table T1a may be changed.
[0096] According to this embodiment, in addition to the effects of the first embodiment, the following effects can be obtained. The display unit 44 displays the work items 6a of the injection molding machine 2 and the work items 6b of the peripheral equipment 3 in different display forms as the second identification display 10a for distinguishing between the work items 6a of the injection molding machine 2 and the work items 6b of the peripheral equipment 3. This allows the worker to easily and reliably visually distinguish whether the work items 6a, 6b are the work items 6a of the injection molding machine 2 or the work items 6b of the peripheral equipment 3, thereby improving work efficiency.
[0097] 3. Embodiment 3 Next, the management screen W1b displayed by the display unit 44 of the molding machine management system 1 according to the third embodiment will be described with reference to Fig. 6. Note that the same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. The management screen W1b according to the third embodiment includes a table T1b. The third embodiment is similar to the first embodiment, except that in the table T1b, the progress status of the work items 6a, 6b is displayed in different display forms depending on the progress status of the work items 6a, 6b.
[0098] As shown in FIG. 6, in the third embodiment, the display form of a cell at the intersection of a row and a column in the body of table T1b differs depending on the progress displayed in the cell. For example, cell 7j, where the column for job 1 intersects with the row for material drying, displays the progress status of material drying corresponding to job 1. Since material drying corresponding to job 1 is a task in progress, cell 7j displays the progress rate of material drying corresponding to job 1 and the scheduled completion time of material drying corresponding to job 1, and the background of cell 7j is displayed with a light shaded area.
[0099] Similarly, cell 7k displays the progress of temperature controller installation corresponding to job 1, and cell 7m displays the progress of manifold cooling corresponding to job 1. Since the tasks corresponding to cells 7k and 7m are tasks currently being performed, the progress rate and estimated completion time of each task are displayed in cells 7k and 7m, and the backgrounds of cells 7k and 7m are lightly shaded.
[0100] In cell 7n, which displays the progress of the hopper heating corresponding to job 1, since the hopper heating corresponding to job 1 has been completed, a white check mark is displayed as a symbol indicating completion, and the background of cell 7n is displayed with a dark shaded area.
[0101] Cell 7e displays the progress of the trial shot corresponding to job 1, cell 7f displays the progress of the temperature controller installation corresponding to job 2, and cell 7g displays the progress of the resin change purging corresponding to job 2. Since the tasks corresponding to cells 7e, 7f, and 7g are tasks that have not been performed, a hyphen is displayed in cells 7e, 7f, and 7g as a symbol indicating that the tasks have not been performed, and the background of the cells is displayed in unshaded white.
[0102] Cells 7k, 7j, 7m, 7n, 7e, 7f, and 7g are examples of cells where rows and columns intersect in the body of table T1b, and in this embodiment, cells where rows and columns intersect in the body of table T1b are displayed in different display forms, that is, with different shading, similar to cells 7k, 7j, 7m, 7n, 7e, 7f, and 7g, depending on the progress displayed in the cell.
[0103] In addition, different display forms are not limited to changing the shading of a cell, but may include changing the background color of a cell, the borders of a cell, changing the color or font of letters or numbers displayed in a cell, adding symbols such as icons, and any other display form may be used.
[0104] According to this embodiment, in addition to the effects of the first embodiment, the following effects can be obtained. The display unit 44 displays the progress status of the work item 6b of the injection molding machine 2 and the progress status of the work item 6b of the peripheral equipment 3 in different display forms depending on the progress status of the work item 6a of the injection molding machine 2 and the progress status of the work item 6b of the peripheral equipment 3, thereby allowing the worker to easily and reliably visually distinguish the progress status of the work items 6a, 6b, thereby improving work efficiency.
[0105] 4. Embodiment 4 Next, a management screen W1c displayed by the display unit 44 of the molding machine management system 1 according to the fourth embodiment will be described with reference to Fig. 7. Note that the same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. The management screen W1c according to the fourth embodiment includes a table T1c. The fourth embodiment is similar to the first embodiment, except that a third identification display 70 for identifying manual work and machine work is displayed for the work items 6a and 6b in the table T1c.
[0106] In this disclosure, "human work" refers to work that places a high workload on the worker. The workload of the worker is also called the human load, and the human work is also called the manual work. In this disclosure, "machine work" refers to work that places a low workload on the worker. In this disclosure, the workload of the worker is a concept that includes the time that the worker is confined to perform the work.
[0107] For example, in this embodiment, among the work items 6b for the peripheral equipment 3, the installation of the temperature regulator is a task in which an operator moves the temperature regulator near the injection molding machine 2 and installs it, which is a task that places a high workload on the operator and corresponds to manual work. Among the work items 6a for the injection molding machine 2, the pre-production purging is a task that an operator performs while monitoring the discharge status of the material discharged from the injection unit 23 of the injection molding machine 2, which corresponds to manual work. Additionally, among the work items 6b of the peripheral equipment 3, material drying includes the work of an operator loading and unloading the material for the molded product into and from the dryer, and the work of an operator inputting specified information into the dryer; however, it takes several hours or more to dry the material in the dryer, and while the dryer is drying the material, the operator is not tied up in drying the material, so this falls under machine work. The third identification display 70 may be displayed according to a division between manual work and machine work that is preset by the manager for each of the work items 6a and 6b.
[0108] 7, in the fourth embodiment, in a column on the front side of table T1c, a work item 6a of the injection molding machine 2 included in the setup work 6 of the injection molding machine 2 and a work item 6b of the peripheral device 3 included in the setup work 6 of the injection molding machine 2 are displayed, and a third identification display 70 for distinguishing between manual work and machine work is displayed for the work items 6a and 6b. In this embodiment, the third identification display 70 for distinguishing between manual work and machine work includes an icon 70a indicating that it is a manual work and an icon 70b indicating that it is a machine work.
[0109] For example, in a column located on the front side of table T1c, a cell 61a displaying material drying, which is a work item 6b of the peripheral device 3, displays an icon 70b indicating that it is a machine work as a third identification indicator 70 for distinguishing between manual work and machine work. Similarly, a cell 61b displaying pre-production purging, which is a work item 6a of the injection molding machine 2, displays an icon 70a indicating that it is a manual work as a third identification indicator 70.
[0110] Meanwhile, for example, in a column located on the front side of table T1c, cell 61c displaying temperature regulator installation, which is the work item 6b of peripheral device 3, displays icon 70a indicating that it is manual work as third identification 70 for distinguishing between manual work and machine work. Similarly, cell 61d displaying manifold temperature lowering, which is the work item 6a of injection molding machine 2, displays icon 70b indicating that it is machine work as third identification 70.
[0111] In this manner, by displaying the third identification display 70 for distinguishing between manual work and machine work, the worker can understand whether the work items 6a, 6b are manual work or machine work.
[0112] In this embodiment, the third identification mark 70 for distinguishing between manual work and machine work is an icon 70a indicating manual work and an icon 70b indicating machine work; however, the third identification mark 70 is not limited to the icons 70a and 70b, and any display form may be used, such as changing the background color, shading, lines, etc. of the cells in the columns located on the front side of table T1c, or changing the color or font of the letters and numbers displayed in the cells.
[0113] In this embodiment, the third identification display 70 for distinguishing between manual work and machine work is an icon 70a indicating manual work and an icon 70b indicating machine work, but either the icon 70a or the icon 70b may be used. When either the icon 70a or the icon 70b is used, for example, the work items 6a and 6b with the icon 70a indicating manual work displayed indicate manual work, and the work items 6a and 6b without the icon 70a indicating manual work displayed indicate machine work.
[0114] In this embodiment, the third identification indicator 70 for distinguishing between manual and machine work is displayed in a column located on the front side of table T1c, but it may be displayed in a cell where a row and a column intersect in the body of table T1c. For example, when a job for producing the same molded item is performed multiple times in succession, a work item that is a manual work in the setup work 6 corresponding to the first job may be a machine work in the setup work 6 corresponding to the second or subsequent job. By displaying the third identification indicator 70 for distinguishing between manual and machine work on the body of table T1c, the third identification indicator 70 can be appropriately displayed according to the production plan for the molded product, etc.
[0115] According to this embodiment, in addition to the effects of the first embodiment, the following effects can be obtained. The display unit 44 displays a third identification display 70 for identifying whether the work items 6a of the injection molding machine 2 and the work items 6b of the peripheral equipment 3 are manual work or machine work. This allows the worker to know whether the work items 6a and 6b are manual work or machine work, thereby improving work efficiency.
[0116] 5. Embodiment 5 Next, the management screen W1d and the input screen W4 displayed by the display unit 44 of the molding machine management system 1 according to the fifth embodiment will be described with reference to Fig. 8 and Fig. 9. The same components as those in the fourth embodiment are denoted by the same reference numerals, and the description thereof will be omitted. The display unit 44 according to the fifth embodiment is the same as that of the fourth embodiment, except that the display unit 44 displays a table T1d including a reception unit 8 that receives the selection of specific work items 6a, 6b by the worker in the management screen W1d, and displays an input screen W4 including an input unit 9 for the worker to input the progress status of the specific work items 6a, 6b when the selection of the specific work items 6a, 6b is received in the reception unit 8.
[0117] As shown in Fig. 8, among cells where rows and columns intersect in the body of table T1d, a reception unit 8 that receives a selection by a worker is displayed in cells corresponding to work items 6a and 6b identified as manual work. In this embodiment, an icon is displayed as the reception unit 8. In the body of table T1d, cell 7p is an example of a cell corresponding to work items 6a and 6b identified as manual work. The reception unit 8 is displayed in cell 7p.
[0118] For example, a worker can operate the operation unit 43 of the management device 4 to place a cursor (not shown) over the reception unit 8 displayed in cell 7p, thereby selecting the work corresponding to cell 7p as the specific work item 6a, 6b. Cell 7p is a cell that displays the progress of temperature regulator installation corresponding to job 1. In other words, a worker can select temperature regulator installation corresponding to job 1 as the specific work item 6a, 6b by placing a cursor (not shown) over the reception unit 8 displayed in cell 7p. In other words, the reception unit 8 displayed in cell 7p accepts the selection of temperature regulator installation corresponding to job 1 as the specific work item 6a, 6b.
[0119] As shown in FIG. 9, when the selection of specific work items 6a, 6b is accepted by the accepting unit 8, the display unit 44 displays an input screen W4 including an input section 9 for the worker to input the progress status of the specific work items 6a, 6b accepted by the accepting unit 8.
[0120] The input screen W4 includes an input section 9 for inputting the progress of specific work items 6a, 6b accepted by the reception section 8, a molding machine name display field F2 that displays the injection molding machine 2 corresponding to the specific work items 6a, 6b, a job display field F3 that displays the job corresponding to the specific work items 6a, 6b, a work item display field F4 that displays the specific work items 6a, 6b, a decision button B4, and a cancel button B5.
[0121] The input unit 9 is a field in which the worker inputs the progress status of the specific work items 6a and 6b accepted by the accepting unit 8. In this embodiment, the input unit 9 is configured as a pull-down menu that allows the worker to input a progress rate as the progress status of the specific work items 6a and 6b.
[0122] For example, when the reception unit 8 displayed in cell 7p in table T1d of the management screen W1d receives a selection of temperature controller installation corresponding to job 1 as a specific work item 6a, 6b, the display unit 44 displays an input screen W4 for inputting the progress status of temperature controller installation corresponding to job 1. At this time, the molding machine name display field F2, job display field F3, and work item display field F4 on the input screen W4 respectively display the molding machine name, job, and work items 6a, 6b corresponding to cell 7p in table T1d of the management screen W1d. The worker operates a cursor (not shown) to input a progress rate as the progress status of temperature controller installation corresponding to job 1 into the input unit 9 displayed on the input screen W4.
[0123] When the worker inputs the progress status of temperature regulator installation corresponding to job 1 into input unit 9 and then operates a cursor (not shown) to press decision button B4, display unit 44 accepts the progress status of temperature regulator installation corresponding to job 1 inputted into input unit 9 and displays management screen W1d with the updated progress status of temperature regulator installation corresponding to job 1. On the other hand, when the worker presses cancel button B5, display unit 44 displays management screen W1d without accepting the input of the progress status of temperature regulator installation corresponding to job 1.
[0124] According to this embodiment, in addition to the effects of the fourth embodiment, the following effects can be obtained. A reception unit 8 is displayed for receiving selection of specific work items 6a, 6b among the work items 6a of the injection molding machine 2 and the work items 6b of the peripheral equipment 3, which are identified as manual work, and when the selection of the specific work items 6a, 6b is received in the reception unit 8, an input unit 9 for inputting the progress status of the specific work items 6a, 6b is displayed, so that the worker can specifically input the progress status of the work items 6a of the injection molding machine 2 and the work items 6b of the peripheral equipment 3, which are identified as manual work. In other words, the worker can specifically grasp the current progress status, not the progress rate calculated, for example, by (elapsed time from the start of work of the work items 6a, 6b to the present) / (standard work time of the work items 6a, 6b), and thus the work efficiency is improved.
[0125] In this embodiment, the reception unit 8 that receives the selection of the worker is displayed as an icon, but the reception unit 8 may be displayed in a form other than an icon. For example, the background of a cell displayed in the body of the table T1d may function as the reception unit 8.
[0126] 6. Embodiment 6 Next, the input screen W4a displayed by the display unit 44 of the molding machine management system 1 according to the sixth embodiment will be described with reference to Fig. 10. The same components as those in the fifth embodiment are given the same reference numerals, and the description thereof will be omitted. The display unit 44 according to the sixth embodiment is the same as that of the fifth embodiment, except that the input screen W4a includes an input unit 9a for the worker to input the progress status of specific work items 6a and 6b.
[0127] As shown in FIG. 10, the input screen W4a includes an input section 9a for inputting the progress of specific work items 6a, 6b accepted by the reception section 8, a molding machine name display field F2 that displays the injection molding machine 2, a job display field F3, a work item display field F4, a decision button B4, and a cancel button B5.
[0128] In this embodiment, the input unit 9a is a list-format table including element tasks 90 included in the specific work items 6a, 6b received by the receiving unit 8, and check boxes 91 indicating the implementation status of the element tasks 90. The element tasks 90 included in the specific work items 6a, 6b are arranged in one column. The check boxes 91 indicating the implementation status of the element tasks 90 are arranged in a column adjacent to the column in which the element tasks 90 are displayed, so as to correspond to each element task 90.
[0129] When a worker performs an element task 90 included in a specific work item 6a, 6b, the worker operates a cursor (not shown) to input information into a check box 91 corresponding to the performed element task 90. When the worker inputs information into the check box 91, a check mark is displayed in the check box 91 corresponding to the performed element task 90. In other words, the number of check marks in the check box 91 indicates the progress status of the specific work item 6a, 6b selected by the worker. For example, the progress rate as the progress status of the specific work item 6a, 6b can be calculated by (the number of check boxes 91 with check marks displayed) / (the total number of check boxes 91).
[0130] In this embodiment, as an example of the input screen W4a, an input screen W4a when the specific work items 6a and 6b accepted by the accepting unit 8 are temperature regulator installation corresponding to job 1 will be described.
[0131] An input section 9a is displayed on the input screen W4a for inputting the progress status of the temperature regulator installation corresponding to job 1. Then, as element tasks 90 included in the temperature regulator installation, "supply of cooling water," "check pressure of supplied cooling water," "check water temperature," etc. are displayed, and check boxes 91 corresponding to each element task 90 are displayed adjacent to each element task 90.
[0132] Among the element tasks 90, the worker inputs information into check boxes 91 corresponding to element tasks 90 that have been performed by the worker, such as supplying cooling water and checking the pressure of the supplied cooling water, and a check mark is displayed in each check box 91. Among the element tasks 90, the worker does not input information into check boxes 91 corresponding to element tasks 90 that have not been performed, such as checking the water temperature, and no check mark is displayed.
[0133] When the worker operates a cursor (not shown) and presses the decision button B4, the display unit 44 accepts the progress status of temperature regulator installation corresponding to job 1 inputted to the input unit 9a and displays the management screen W1d with the updated progress status of temperature regulator installation corresponding to job 1. On the other hand, when the worker presses the cancel button B5, the display unit 44 displays the management screen W1d without accepting the progress status of temperature regulator installation corresponding to job 1 inputted to the input unit 9a.
[0134] According to this embodiment, in addition to the effects of the fifth embodiment, the following effects can be obtained. The input section 9a is a list-type table including element tasks 90 included in specific work items 6a, 6b selected by the worker and check boxes 91 indicating the implementation status of the element tasks 90. This enables the worker to reliably implement the element tasks 90 included in the specific work items 6a, 6b, thereby improving work efficiency.
[0135] 7.Embodiment 7 Next, a management screen W1e displayed by the display unit 44 of the molding machine management system 1 according to the seventh embodiment will be described with reference to Fig. 11. Note that the same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. The management screen W1e according to the seventh embodiment includes a table T1e. The seventh embodiment is similar to the first embodiment, except that a fourth identification display 74 for identifying the process type is displayed in the table T1e for the work items 6a of the injection molding machine 2 and the work items 6b of the peripheral equipment 3.
[0136] The process types include external setup and internal setup. In this disclosure, "external setup" refers to the work items 6a and 6b included in the setup work 6 of the injection molding machine 2 that can be performed without stopping the injection molding machine 2, and "internal setup" refers to the work items 6a and 6b included in the setup work 6 of the injection molding machine 2 that cannot be performed unless the injection molding machine 2 is stopped.
[0137] For example, in this embodiment, among the work items 6b of the peripheral equipment 3, material drying is a work that is performed independently of the injection molding machine 2 using a dryer used for drying the material, and is a work that can be performed in parallel with the work item 6a of the injection molding machine 2 without stopping the injection molding machine 2. Therefore, material drying corresponds to external setup. Among the work items 6b of the peripheral equipment 3, temperature regulator installation is a work that cannot be performed unless the injection molding machine 2 is stopped, and corresponds to internal setup. Also, among the work items 6a of the injection molding machine 2, manifold temperature reduction and waste injection are works that cannot be performed unless the injection molding machine 2 is stopped, and correspond to internal setup.
[0138] As shown in FIG. 11, in embodiment 7, a column located on the front side of table T1e displays a work item 6a of the injection molding machine 2 included in the setup work 6 of the injection molding machine 2 and a work item 6b of the peripheral equipment 3 included in the setup work 6 of the injection molding machine 2, and a second identification display 10 for identifying the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral equipment 3 is displayed in a column adjacent to the front side opposite the front body of table T1e, and further, a fourth identification display 74 for identifying the process type is displayed in a column adjacent to the column in which the second identification display 10 is displayed, on the opposite side of the front side.
[0139] The fourth identification indicator 74 is provided to clearly indicate to the worker whether the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3 displayed on the front side of the table T1e are external setup or internal setup. Specifically, the display unit 44 displays two types, external setup and internal setup, as the fourth identification indicator 74.
[0140] According to this embodiment, in addition to the effects of the first embodiment, the following effects can be obtained. The display unit 44 displays a fourth identification display 74 for identifying process types including external setup and internal setup for the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3. This allows the worker to know whether the work items 6a and 6b are external setup or internal setup, thereby improving work efficiency.
[0141] 8.Embodiment 8 Next, a management screen W1f displayed by the display unit 44 of the molding machine management system 1 according to the eighth embodiment will be described with reference to Fig. 12. Note that the same components as those in the seventh embodiment are given the same reference numerals, and the description thereof will be omitted. The management screen W1f according to the eighth embodiment includes a table T1f. The eighth embodiment is the same as the seventh embodiment except that the fourth identification indicator 74a for identifying the process type in the table T1f is different. In the eighth embodiment, the display unit 44 displays the work items 6a of the injection molding machine 2 and the work items 6b of the peripheral device 3 as the fourth identification indicator 74a in a display form that differs for each process type.
[0142] As shown in FIG. 12, in the eighth embodiment, among the columns adjacent to the column in which the second identification mark 10 is displayed on the opposite side of the front side of the table T1f, there is no column on the opposite side of the front side of the table T1f, and the fourth identification mark 74a for identifying the process types including external setup and internal setup is realized by giving a different display form to a part of the table T1f.
[0143] In this embodiment, the display unit 44 displays the work items 6a of the injection molding machine 2 included in the setup work 6 of the injection molding machine 2 and the work items 6b of the peripheral device 3 included in the setup work 6 of the injection molding machine 2 in the columns located on the front side of table T1f, and displays the background of the cell corresponding to the external setup with light shading as the fourth identification display 74a, and displays the background of the cell corresponding to the internal setup with white without shading as the fourth identification display 74a. That is, in the columns located on the front side of table T1f, the cells corresponding to the external setup and the cells corresponding to the internal setup are displayed with different shading, which is a different display form for each process type corresponding to the work items 6a, 6b displayed in each cell.
[0144] For example, in this embodiment, among the work items 6b of the peripheral device 3, material drying corresponds to external setup, so the background of cell 60f displaying material drying in the column located on the front side of table T1f is displayed with light shading. Also, for example, temperature controller installation, manifold temperature reduction, and dumping correspond to internal setup, so the backgrounds of cells 60g, 60h, and 60j corresponding to each work are displayed in white with no shading.
[0145] The different display forms are not limited to changing the shading of the cells, but may be any display form such as changing the background color of the cells, the borders of the cells, changing the color or font of the letters or numbers displayed in the cells, adding symbols such as icons, etc. In the present embodiment, the display form of the cells in the columns located on the front side of table T1f is changed as the fourth identification mark 74a, but it is not limited to the cells in the columns located on the front side of table T1f, and for example, the display form of the row including the cells in the columns located on the front side of table T1f may be changed.
[0146] According to this embodiment, in addition to the effects of the seventh embodiment, the following effects can be obtained. The display unit 44 displays the work items 6a of the injection molding machine 2 and the work items 6b of the peripheral equipment 3 in different display forms for each process type as the fourth identification display 74a for identifying the process type, so that the worker can easily and reliably visually distinguish whether the work items 6a, 6b are external setup or internal setup, respectively, thereby improving work efficiency.
[0147] 9. Embodiment 9 Next, a management screen W1g displayed by the display unit 44 of the molding machine management system 1 according to the ninth embodiment will be described with reference to Fig. 13. Note that the same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. The management screen W1g according to the ninth embodiment includes a table T1g. The ninth embodiment is similar to the first embodiment, except that a fifth identification display 75 is displayed in table T1g, which indicates the chronological relationship of the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3 according to the execution order of the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3.
[0148] 13, the display unit 44 displays a fifth identification indicator 75. Specifically, in this embodiment, the display unit 44 displays an arrow, which is a symbol, as the fifth identification indicator 75, superimposed on the column located on the front side of the table T1g, i.e., the column in which the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3 are displayed.
[0149] The fifth identification indicator 75 may be a symbol other than an arrow as long as it indicates the ante-post relationship of the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3 according to the execution order of the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral device 3. The fifth identification indicator 75 may be displayed in a form other than a symbol. The position where the fifth identification indicator 75 is displayed may be a position other than a column located on the front side of the table T1g.
[0150] According to this embodiment, in addition to the effects of the first embodiment, the following effects can be obtained. The display unit 44 displays the fifth identification display 75 indicating the chronological relationship of the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral equipment 3 in accordance with the execution order of the work item 6a of the injection molding machine 2 and the work item 6b of the peripheral equipment 3, thereby enabling the worker to easily and reliably visually distinguish the execution order of the work items 6a, 6b, thereby improving work efficiency.
[0151] 10. Embodiment 10 Next, the management screen W1h displayed by the display unit 44 of the molding machine management system 1 according to the tenth embodiment will be described with reference to Fig. 14. The same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted. The management screen W1h according to the tenth embodiment includes a table T1h. The tenth embodiment is the same as the first embodiment, except that in the table T1h, in addition to the work items 6a and 6b corresponding to the pre-setup among the setup work 6 of the injection molding machine 2, a work item 6c corresponding to the post-setup among the setup work 6 of the injection molding machine 2 is displayed.
[0152] 14, the columns on the front side of table T1h display work items 6a of the injection molding machine 2 and work items 6b of the peripheral devices 3 which correspond to pre-setup among the setup work 6 of the injection molding machine 2, and work item 6c which corresponds to post-setup among the setup work 6 of the injection molding machine 2. In other words, the setup work 6 of the injection molding machine 2 includes work items 6a and 6b as pre-setup work and work item 6c as post-setup work, and the display unit 44 displays, as the setup work 6 of the injection molding machine 2, the work items 6a and 6b which correspond to pre-setup work and the work item 6c which corresponds to post-setup work.
[0153] In this embodiment, the work items 6c displayed are "mold cooling" and "mold removal," which are work items for the injection molding machine 2. Mold cooling and mold removal are examples of work corresponding to the post-stage among the setup work 6 for the injection molding machine 2. Mold cooling is a work of cooling the mold 26 attached to the injection molding machine 2, and mold removal is a work of removing the cooled mold 26 from the injection molding machine 2. Work items 6c corresponding to the post-stage among the setup work 6 for the injection molding machine 2 are not limited to mold cooling and mold removal, and may include other work. For example, mold cooling and mold removal are work for the injection molding machine 2, but may include work for the peripheral device 3.
[0154] In this way, the display unit 44 displays work items 6a, 6b corresponding to pre-setup work and work item 6c corresponding to post-setup work as the setup work 6 of the injection molding machine 2, so that the worker can understand not only the pre-setup work but also the post-setup work, thereby improving work efficiency.
[0155] In this embodiment, in the columns located on the front side of table T1h, the backgrounds of the cells of the work items 6a and 6b corresponding to pre-setup work are displayed in white without any shading, and the backgrounds of the cells of the work items 6c corresponding to post-setup work are displayed in light shading. In this way, the work items 6a and 6b corresponding to pre-setup work and the work item 6c corresponding to post-setup work are displayed in different display forms of shading depending on whether the work items 6a, 6b, and 6c are pre-setup work or post-setup work, so that the worker can visually easily and reliably distinguish whether the work items 6a, 6b, and 6c are pre-setup or post-setup, respectively, and work efficiency is improved.
