  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a hardware configuration of a parts list creation device 10 of a twin screw extruder according to the present embodiment. A parts list creation device 10 for a twin screw extruder includes a nonvolatile memory 11, a memory 12, an operation device 13, a display device 14, and a CPU (Central Processing Unit) 15.

  The nonvolatile memory 11 stores data such as a screw shape file and an owned screw list, various programs, and the like. Nonvolatile memory 11 can be transmitted via a magnetic tape, magnetic disk (hard disk drive, etc.), optical disk (CD-ROM, DVD disk, etc.), magneto-optical disk (MO, etc.), flash memory, etc., and via a network. Examples of the medium include all media that can be read and executed by a computer. The memory 12 temporarily stores data such as a screw shape file and an owned screw list, various programs, calculation results of the CPU 15, and the like.

  The operation device 13 is a device for a user to perform various operations via a screen, a keyboard, a mouse, and the like. The display device 14 is a device that displays a calculation result of the CPU 15, a screw shape file, and the like. The CPU 15 performs the classification of the screw type such as the screw form factor, the calculation of the number of held screws, the instruction to display the calculation result on the display device 14, and the storage of the held screw list in the nonvolatile memory 11. In the present embodiment, the screw form factor includes a screw length, a screw lead, a disk displacement angle, the number of disks, a screw outer shape, and the like. In addition to the screw form factor, the possessed screw list includes a stamp number and the like.

  Next, operation | movement of the components list preparation apparatus 10 of a biaxial screw extruder is demonstrated. FIG. 2 is a flowchart showing the operation of the parts list creation device 10 of the twin screw extruder according to the present embodiment. In the following description, the hardware configuration shown in FIG. 1 may be used. Moreover, the operation | movement shown below is performed by the hardware (computer) shown in FIG. 1 by the parts list preparation program of a twin-screw extruder.

  As shown in FIG. 2, the parts list creation device 10 of the twin-screw extruder has a means for creating a retained screw list based on an existing screw shape file, a screw type and the number of screws, and the retained screw list. Generating means.

  First, a means for creating a possessed screw list from an existing screw shape file will be described. After the parts list creation device 10 of the twin screw extruder is activated, the CPU 15 reads an existing screw shape file stored in the nonvolatile memory 11 (S1). Then, the CPU 15 calculates the screw type and the number thereof based on the data (screw shape data) of the existing screw shape file (S2). Thereafter, the CPU 15 creates a retained screw list based on the calculation result (S5), and stores the retained screw list in the nonvolatile memory 11.

  Next, a means for creating a possessed screw list by inputting the screw type and the number thereof will be described. After the parts list creation device 10 of the twin-screw extruder is activated, the screw object screen is selected by the user, and the screw shape factor and the number of the screw shape factors are input (S3). Then, it is determined whether or not the user has entered the shape factor and the number of all the retained screws (S4). If it is determined that the input has been made (S4, yes), the CPU 15 creates a possessed screw list (S5), and stores the retained screw list file in the nonvolatile memory 11 (S6). On the other hand, when it is determined that there is a shape factor or the like that has not been input (S4, no), the process returns to S3.

  Below, in order to demonstrate operation | movement of the parts list preparation apparatus 10 of a biaxial screw extruder more in detail, it demonstrates according to the transition screen of the parts list preparation apparatus 10 of a biaxial screw extruder. In the following, of the two types of operations shown in FIG. 2, an operation for creating the owned screw list from the existing screw shape file will be described.

  FIG. 3 is a diagram showing an operation screen of the part shape creation software of a typical twin screw extruder. FIG. 4 is a diagram showing a screen for selecting a “create screw list from screw diagram” command. FIG. 5 is a diagram showing a screen for creating an owned screw list from a screw diagram. FIG. 6 is a diagram showing a screen for reading an existing screw diagram. FIG. 7 is a diagram showing a possessed screw list. FIG. 8 is a diagram showing a screen for storing the owned screw list.

  First, a screw shape file as shown in FIG. 3 is created for two extruders and stored in advance. The screw shape file is created by the user selecting a screw, a cylinder, and a nozzle from the nozzle object on the left side of the screen shown in FIG.

  And after starting the components list preparation apparatus 10 of a biaxial screw extruder, the above-mentioned existing screw shape file is read, and the data of the existing screw shape file are displayed on a screen. Then, as shown in FIG. 4, the “Create screw list from screw diagram” command is selected from the “Edit” menu of the menu bar, and a screen for creating a screw list from the screw diagram is displayed as shown in FIG. Is done. When the screen shown in FIG. 5 is displayed, a screw list corresponding to the screw type is not created.

  Next, as shown in FIG. 6, the screw shape files of the two existing screw extruders shown in FIG. 4 are selected, and the screw shape files of the twin screw extruder are read. Then, as shown in FIG. 7, the two existing screw shape files read in FIG. 6 are classified for each shape factor to create a retained screw list. The shape factors and the like shown in FIG. 7 are classified for each dimension input when the screw shape shown in FIG. 3 is configured, for example. With the screen shown in FIG. 7, the retained screw list is created with the operation result obtained by adding the number of screws for each screw type in the two twin-screw extruders as the retained number.

  For this reason, the user does not need to individually input each of the shape factors such as the screw length, lead, and multiplier shown in FIG. 7, and can create the owned screw list only by reading the existing screw shape file.

  Finally, the “save command” on the toolbar shown in the upper left of FIG. 7 is selected, and the owned screw list is saved on the saved screw list saving screen shown in FIG.

  Next, operation | movement of the components management apparatus of a twin screw extruder is demonstrated. Note that the hardware configuration of the component management device of the twin screw extruder is the same as that of the component list creation device 10 of the twin screw extruder, and the description thereof is omitted. In the following, description will be given using each configuration of the hardware shown in FIG. Moreover, the operation | movement shown below is performed by the hardware shown in FIG. 1 by the component management program of a twin-screw extruder.

  FIG. 9 is a flowchart showing the operation of the component management device of the twin screw extruder according to the present embodiment. First, the user activates the component management device of the twin screw extruder. And CPU15 reads the possessed screw list preserve | saved by the non-volatile memory 11 by the components list preparation apparatus 10 of a biaxial screw extruder (S11). The CPU 15 causes the display device 14 to display a retained screw list such as a screw type and the number of retained screws (S12).

  Next, the user determines whether a screw shape file is necessary (S13). When it is determined that it is necessary (S13, yes), the CPU 15 reads the screw shape file from the nonvolatile memory 11 (S14). Then, the “display screw usage status” function is selected by the user (S15). On the other hand, when it is determined that it is not necessary (S13, no), the process proceeds to S15.

  Next, the CPU 15 calculates the screw type and the screw holding number (S16), and on the screw usage status screen, for each screw type and screw holding number, the screw holding number, the set number by the screw shape file, and the remaining screw holding by the calculation result The number is displayed on the screw usage status screen (display device 14) (S17).

  Next, the user determines whether or not to print the display content of the display device 14 (S18). If it is determined to print (S18, yes), the CPU 15 causes the printer (not shown) to print the possessed screw list displayed on the display device 14 (S19). Then, it is determined whether or not the owned screw list is stored in the nonvolatile memory 11 by the user (S20). On the other hand, if it is determined not to print (S18, no), the process proceeds to S20. When it is determined by the user that the owned screw list is to be saved (S20, yes), the CPU 15 saves the owned screw list in the nonvolatile memory 11 (S21), and the operation ends. If it is determined not to save (S20, no), the operation is terminated.

  In the following, in order to explain the operation of the component management device of the twin screw extruder in more detail, the component management device of the twin screw screw extruder will be described with respect to the operation of calculating the remaining number of retained screws from the retained screw list and the screw shape file. This will be explained according to the transition screen.

  FIG. 10 is a diagram showing an operation screen for calculating the number of screws held. FIG. 11 is a diagram showing a screen for selecting an “Open” command for reading the owned screw list. FIG. 12 is a diagram illustrating a screen for reading a possessed screw list. FIG. 13 is a diagram illustrating an operation screen on which the owned screw list is displayed. FIG. 14 is a diagram showing a screen for selecting a “display screw usage status” command. FIG. 15 is a diagram showing a screw usage status display screen. FIG. 16 is a diagram showing a screen for selecting the “Add screw shape file from list” command. FIG. 17 is a diagram showing a screen for reading a screw shape file. FIG. 18 is a view showing a screen showing an improved screw shape of the second twin-screw extruder. FIG. 19 is a diagram showing a screen for selecting a “display screw usage status” command. FIG. 20 is a diagram illustrating a screen in which a list of screws whose number of possessions is to be changed is selected. FIG. 21 is a diagram showing an operation screen for changing the list of screws selected in FIG. FIG. 22 is a diagram showing a screw usage status screen after subtracting the used screw from the owned screw list.

  First, as shown in FIG. 10, after starting an operation screen for calculating the number of owned screws, as shown in FIG. 11, an “Open” command is selected from the “File” menu of the tool bar. Then, as shown in FIG. 12, the owned screw list created by the parts list creating device 10 of the twin screw extruder is read, and as shown in FIG. 13, the owned screw list is displayed on the owned screw list display screen of the operation screen. Is displayed.

  Next, as shown in FIG. 14, the “display screw usage” command is selected from the “display” menu of the menu bar, and the number of remaining retained lists based on the number of retained screws and the number of used screws (number of sets). Is performed. Then, the calculation result is displayed as shown in FIG.

  The screen shown in FIG. 15 shows the screw type and each form factor for each screw type. Also, in the first to third columns from the right, the number of screws held, the number of sets, and the number of remaining screws are shown for each screw type. These are results calculated based on the retained screw list and the screw shape file created by the parts list creation device 10 of the twin screw extruder. At this stage, since only the owned screw list is calculated without reading out the screw shape file, the number of sets becomes 0 as shown in FIG.

  Next, as shown in FIG. 16, an “add screw shape file from the list” command is selected from the edit menu of the operation screen, and as shown in FIG. Unit improvement file is selected. Note that the Unit 2 improved file is a file in which the screw shape of Unit 2 is slightly changed. As shown in FIG. 18, the improvement file for No. 2 is read by the part shape creation software of the twin screw extruder as shown in FIG. 3, and is changed appropriately using the nozzle object on the left side of FIG. Created.

  Next, as shown in FIG. 19, after a screen on which two screw shape files have been read is displayed, as shown in FIG. 20, a screw type whose number of screws to be changed is selected. Then, as shown in FIG. 21, the properties of the selected screw type are displayed, and the numerical value in the “Number of owned” column is changed from 13 to 15. In the operation screen shown in FIG. 21, in addition to the number of possessions, it is possible to collectively set the outer shape and the engraving number according to the screw type, and newly add a new screw type, its shape factor and the number of possessions. It is also possible to update the owned screw list.

  After the information regarding the screw type is changed in this way, as shown in FIG. 19, the “display screw usage status” command in the “display” menu of the menu bar is selected. Then, after the number of remaining retained screws is calculated based on the retained screw list and screw shape file data shown in FIG. 19, the calculation result is displayed as shown in FIG.

  The calculation results shown in FIG. 22 are calculated based on the two types of information of the possessed screw list and the screw shape file as described above. Therefore, unlike the screw usage situation shown in FIG. 15, the number of sets currently used is displayed in the set number column and the remaining number of holdings is subtracted from the calculation result shown in FIG. Is displayed.

  Here, in the calculation result shown in FIG. 22, there is a screw type displaying “−” as the remaining number of possessions. This means that there are not enough screw types indicating “−” when the current number of held screws is used as a reference. In other words, the configuration of the improved screw plan for Unit 2 indicates that it is not possible at this time.

  As described above, according to the present embodiment, the user can manage the screw only by operating the command on each screen with the mouse of the computer or the like. For this reason, the ease of management can be greatly improved compared with the function that is required to input numerical values by the conventional keyboard operation, and can greatly contribute to the reduction of labor and time.

  As an example, a holding screw list for two twin screw extruders was similarly created using the parts list creation device 10 of the twin screw extruder according to the present embodiment. As a result, the work could be completed in 2 minutes.

  On the other hand, a possessed screw list for two twin screw extruders was created using Excel manufactured by Microsoft (registered trademark). For full-flight screws, the screw length, screw lead, and screw profile were integrated into the management items using the screw length, disc displacement angle, number of disks, and screw profile as the shape factors. As a result, it took 30 minutes.

  In other words, it can be said that the same shortening was achieved in the labor for creating the owned screw list. Further, referring only to these examples, the list creation time can be reduced to 1/15 in this embodiment.

  Furthermore, in this embodiment, not only full flight screws and kneading discs but also all screw elements that can be drawn with the part shape creation software of a twin screw extruder as shown in FIG. 3 can be handled. Become. For this reason, screws having different shape factors such as notched flight screws, gear kneading disks, and rings can be easily managed in an integrated manner.

  In the present embodiment, the calculation result for all items of the screw type shape factor is shown in the screw usage status screen shown in FIG. 22, but the item selection screen shown in FIG. It becomes possible to calculate again after removing the check. For example, when it is desired to create a screw list that does not require the screw length, batch management can be performed by unchecking the item “L / D”. Therefore, management that has been difficult with the conventional screw management method using spreadsheet software can be performed.

  Further, as shown in FIG. 24, from the two owned screw lists of No. 1 and No. 2 created by the parts list creation device 10 of the twin screw extruder, the owned screw lists of the improved shapes of No. 1 and No. 2 are obtained. Newly created. This procedure is as follows.

  First, a base list file is selected from a “reference” command. Then, the second machine improvement file is selected from the “add” command as the addition list file, and the second machine file is selected from the “add” command as the subtraction list file. Thereafter, as shown in FIG. 25, when the owned screw list reflecting the screw list improved from Unit 2 is stored, the addition / subtraction operation is performed based on the base list file shown in FIG. Is stored in the nonvolatile memory 11.

  According to this procedure, the improved shape of Unit 2 can be instantaneously reflected in the possessed screw list, so that the labor and time required for creating the possessed screw list can be shortened.
