Description

  The present invention relates to a mold history display apparatus and a mold press apparatus, and more particularly to a mold history display apparatus and the like capable of displaying in detail a use history and a time history of a mold.

  2. Description of the Related Art Conventionally, press working using a metal mold pressing device for a processing target (object) such as metal or resin has been performed. In press working, the quality of the mold affects the processing accuracy of the object. For example, if the number of times the mold is used exceeds a certain number and the dimensional accuracy of the mold decreases due to wear, the processing accuracy of the object also decreases. Therefore, a management method is performed in which the number of times a machining tool such as a mold or a machining jig is used is managed, and the machining tool is replaced or maintained before the performance of the machining tool deteriorates.

  For example, in Patent Document 1, the cutting tool is managed by distinguishing between cutting during operation and non-cutting by performing air cut detection in an NC cutting machine.

<Mold history display device>
In the first embodiment, the press device S also functions as a mold history display device (hereinafter referred to as a history display device) T. The history display T is for displaying history information (time-lapse information) such as a use history, a storage history, and a maintenance history of the mold 20. By displaying the history information of the mold 20 by the history display T, the user of the press apparatus S grasps not only the number of times and the usage time of the mold 20 but also the storage period and maintenance period of the mold 20. be able to. The influence over time due to storage of the mold 20 and the influence due to the maintenance can be grasped, and the state management of the mold 20 can be performed with higher reliability.

  The history display T includes a history database B, extraction means 15a, and display means 15b. The history database B is a database stored in the memory 14b. The extraction unit 15a and the display unit 15b are functions that the CPU 14a exhibits based on the operation of the history display program P stored in the memory 14b, and the CPU 14a is substantially the extraction unit 15a and the display unit 15b. In the first embodiment, the display screen 16 and the input device 18 further constitute a part of the history display T. An example of the data structure of the history database B is shown in Table 1 below.

  When the identification information C is input from the input device 18 (or the identification information C is read by the identification information sensor when the press device S includes the identification information sensor), the identification information C is stored in the history database B. . When management information related to the identification information C is input from the input device 18, the management information is associated with the identification information C and stored in the history database B.

  For example, use start information (first start information) BS1 which is information indicating a use start time (start time of the first state) of a specific mold 20, and information indicating a use end time (end time of the first state). When certain use end information (first end information) BE1 is input from the input device 18, the use start information (first start information) BS1 and the use end information (first) are associated with the identification information C of the mold 20. 1 end information) BE1 is stored in the history database B. Here, the period from the use start information BS1 to the use end information BE1 is the use period (period corresponding to the first state) B1, and the state corresponding to the use period B1 is the use state (first state) B10 (FIG. 4). Reference).

  When the press device S includes a mounting sensor, information indicating the time when the mounting of the specific mold 20 to the press device S is detected by the mounting sensor is used start information BS1, and the pressing device S of the specific mold 20 is used. Information indicating the time when removal from the camera is detected may be automatically stored in the history database B as the use end information BE1. In this case, it is not necessary to input the use start information BS1 or the use end information BE1 from the input device 18.

  Maintenance start information (second start information) BS2 which is information indicating a maintenance start time (second state start time) of the specific mold 20 and maintenance end information (second state end time) are information indicating the maintenance end time (second state start time). When the end information (second end information) BE2 is input from the input device 18, the maintenance start information BS2 and the maintenance end information BE2 are stored in the history database B in association with the identification information C of the mold 20. The Here, a period from the maintenance start information BS2 to the maintenance end information BE2 is a maintenance period (period corresponding to the second state) B2, and a state corresponding to the maintenance period B2 is a maintenance state (second state) B20. The maintenance state B20 is a state in which maintenance work such as repair or improvement is performed on the specific mold 20, and the maintenance period B2 is a period in which the maintenance state is continued.

  The remaining period excluding the use period B1 and the maintenance period B2 in the specific mold 20 is grasped by the control unit 14 as a storage period (period corresponding to the third state) B3. In this case, the third state is a storage state. Thus, the history database B stores various management information in association with the identification information C of the specific mold 20.

  When the history display program P is executed, the CPU 14a functioning as the extraction unit 15a uses from the history database B the use start information BS1, the use end information BE1, the maintenance start associated with the identification information C of the specific mold 20 Information BS2 and maintenance end information BE2 are extracted.

  When the history display program P is executed, the CPU 14a functioning as the display unit 15b sets the state corresponding to the period between them based on the use start information BS1 and the use end information BE1 extracted by the extraction unit 15a. Is displayed on the display screen 16 in association with the identification information C. An example of the display is shown in FIG. In FIG. 4, as the history information of the mold 20 corresponding to the identification information C, the usage state B10 is displayed as a horizontal bar graph with the horizontal axis as the time axis.

  Based on the maintenance start information BS2 and the maintenance end information BE2 extracted by the extraction means 15a, the CPU 14a functioning as the display means 15b associates the state corresponding to the period between them with the identification information C as the maintenance state B20, and displays the display screen 16 To display. In FIG. 4, as the history information of the mold 20 corresponding to the identification information C, the maintenance state B20 is displayed as a horizontal bar graph with the horizontal axis as the time axis.

  At this time, the use state B10 and the maintenance state B20 are displayed on the screen as distinguished from each other as shown in FIG. At first glance, the usage history and the maintenance history of the mold 20 corresponding to the identification information C can be distinguished and grasped.

  The CPU 14a functioning as the display means 15b sets the storage state B30 to the identification information C so as to correspond to the remaining period (storage period B3) other than the use period B1 corresponding to the use state B10 and the maintenance period B2 corresponding to the maintenance state B20. And displayed on the display screen 16. Thereby, the history information of the mold corresponding to the identification information C is classified into one of the use state B10, the maintenance state B20, and the storage state B30 and displayed on the screen.

<Die history information display procedure>
