Description

  The present invention relates to a tool setup time display device for a punch press that displays a setup occurrence time for tool change in a scheduled operation.

  Some punch presses using turrets and the like are used by exchanging tools attached to the turrets depending on the processing contents. For example, in the multi-turret type punch press using a turret type tool equipped with a plurality of unit tools as the above-mentioned tool, there is a tool that performs a schedule operation by frequently replacing the turret type tool mounted on the tool magazine. The tool exchange setup is performed when a unit schedule, which is a schedule for executing one machining program, is completed.

  In such a punch press for exchanging and mounting tools, it is convenient to create setup information for tool exchange and perform setup according to the setup information in order to efficiently perform tool exchange as the machining schedule progresses. . There are proposals for displaying such setup information on the screen of the operation panel (for example, Patent Documents 1 and 2).

Conventionally, in such a punch press, a setup instruction to an operator is displayed to be performed until the scheduled line is executed. Moreover, although the estimated time of the machining time was obtained from CADCAM or the like, the time display considering the machining schedule line and the number of sheets was not made.
In the punch press, setting and displaying the scheduled machining time and updating the set machining time with the actual machining time are proposed in Patent Document 3, for example.

The setup occurrence time display output means 95 generates the setup occurrence time display 80 and the schedule progress prediction display 88 and outputs them to the display device 47.

As shown in FIG. 2, the guide display 82 is a display of an operation button-shaped mark, for example, a rectangular mark, and the display information output means 71 includes a guide display 82 composed of the button-shaped mark. A tool number display 84 of the turret type tool 7 in which setup occurs, a tool setup occurrence time display 80, and a setup occurrence summary display 85 are displayed. The tool number display 82 is displayed in an inner enclosure display 83 such as a circle shown in the guide display 82 composed of the button-shaped marks. The setup generation outline display 85 indicates the urgency at which setup occurs, for example, whether it is immediate or what number (ie, what line) the unit schedule Sch is being processed from the unit schedule Sch that is currently being processed. It is a display which shows a division.
Several guide displays 82 (for example, 5 or less, 4 or less, or 3 or less) are displayed side by side on the screen and constitute a guide display group 81. The plurality of guide displays 82 are displayed from the one end of the arrangement (the left end in the figure in FIG. 2) in order of the occurrence of the setup. In the case of the same order, rules such as arranging the tool numbers in ascending order are set as appropriate. In FIG. 2, the tool with the tool number “2”, which is a turret type tool 7 that needs to be set up immediately (necessary for the next unit schedule Sch), and the turret type tool 7 in which setup occurs in the second to fifth lines. A guide display 82 is displayed for each of the tool numbers “1” and “11”. In addition, the one-dot chain line in FIG. 2 is a line described for convenience in order to show a part, and is not a line displayed on the screen.

  The schedule progress display 87 is displayed side by side on the same screen as the guide display 82. The schedule progress display 87 is a table in which the file names of the machining programs of the unit schedules Sch constituting the machining schedule SH are displayed side by side in the execution schedule, and the current actual progress status of the machining schedule SH is displayed. More specifically, the schedule progress display 87 indicates the number of materials, the number of products, the number of scheduled processes, the number of completed processes, the number of remaining processes, etc. in each file name line.

As shown in FIG. 3, the schedule progress prediction display 88 displays the file names of the machining programs of the unit schedules Sch constituting the machining schedule SH in the order of execution schedule, and “estimated time” is displayed on the display line of each file name. , “Machining time”, “expected start time”, and “expected end time”. In addition, an execution line display K for displaying the line of the unit schedule Sch currently being executed is displayed by color coding or the like (hatched in the figure).
The “estimated time” is the time registered in the estimated time registration unit 91 (FIG. 1) as the time required for processing one sheet (that is, processing one processing program). The display content of this “estimated time” is updated to one actual processing time in a line above the execution line display K, for example, when there is a processing result. “Processing time” is the time actually required for processing the unit schedule Sch in the display row, and is the time measured by the actual processing time measuring means 92. The “expected start time” is an expected time when the unit schedule Sch of the row is started. The “expected end time” is an expected time when the unit schedule Sch of the row is completed. These “expected start time” and “expected end time” are times calculated by the tool setup occurrence time calculating means 74, but when there is a record of machining, for example, in a line above the execution line display K, It is automatically updated to the value recalculated with the actual machining time.

In FIG. 1, estimated time registration means 91 is means for registering estimated time, which is the time required for processing one plate material by a processing program, and each unit schedule Sch stored in the schedule storage means 45. Registered. This registration is performed from input means such as a keyboard provided on the operation panel 46 or the like or other appropriate means. For the unit schedule Sch that uses the same machining program, the same time may be registered or may be individually registered.
The actual machining time measuring means 92 is means for actually measuring the machining time required to machine one plate material by the machining program. This machining time is obtained, for example, by measuring the time between the machining start signal and the machining completion signal output from the control device 41.
The actual result update means 93 is a means for updating the registered estimated time registered in the estimated time registration means 91 with the actual machining time measured by the actual machining time measuring means 92. The actual result update means 93 may be provided as a part of the tool setup occurrence time calculation means 94.

The tool setup occurrence time calculation means 94 starts the execution of the unit schedule Sch that is executed earliest among the unit schedules Sch in which the setup of the tool searched by the setup occurrence schedule search unit 48a of the setup information generation means 48 occurs. This is a means for calculating the tool setup occurrence time, which is the time, from the registered estimated time registered in the estimated time registration means 91.
In this embodiment, the tool setup occurrence time calculation means 94 calculates the expected start time and the expected end time of each unit schedule Sch from the registered estimated time registered in the estimated time registration means 91.

FIG. 4 is a flowchart showing a procedure for calculating the expected start time of the schedule by the tool setup occurrence time calculation means 94. When the unit schedule Sch is started (step S1), the current time is acquired (S2). The current time is obtained from a timer (not shown) provided in the management device 42.
Thereafter, it is checked whether or not the estimated time is registered in the estimated time registering means 91 (S3). If registered, the number is converted from the estimated registered time and the expected start time of the unit schedule Sch is calculated. . The above-mentioned number conversion is a process of integrating, for example, the number of sheets when processing by the same processing program is continued. The calculation of the expected start time is a process of adding the estimated registration time converted into the number of sheets as described above to the acquired current time.
If the estimated time is not registered, the number of units is converted from the internally set time, and the expected start time of the unit schedule Sch is calculated (S8). The internal setting time is a time that is appropriately set in a predetermined storage area. It should be noted that an appropriate setting value is set as the estimated registration time in the estimated time registration means 91 without setting an internal setting time setting area, and the expected start time is always calculated from the estimated time. Also good. That is, the determination step S3 and the calculation step S8 may be omitted.

  After calculating the expected start time in this way, it is checked whether or not there is an actual time (the machining time measured by the actual machining time measuring means). If there is no actual time, the process returns to step S3 to return to the next unit schedule. Wait for Sch to start. In this case, the time calculated in each of the calculation steps S3 and S8 is directly used as the expected start time.

If there is an actual time, the actual machining time is registered as an estimated time in the estimated time registration means 91 (S6).
The start time of the unit schedule Sch is recalculated based on the estimated time that is the actual machining time thus registered, and the expected start time is updated and displayed in the schedule progress schedule display 88 of FIG. 3 (S7). ). When the predicted end time is displayed as shown in FIG. 3, the predicted end time is also calculated in step S7 and the above-described predicted start time calculation processes (S3, S8). If another screen is displayed without displaying the screen of FIG. 3, the setup occurrence time display output means 74 prepares for the update display, and displays the above update display when the screen is switched. Do.

  The tool setup occurrence time calculation means 94 sets the expected start time of the unit schedule Sch in which setup occurs among the expected start times of each unit schedule Sch calculated in this way as the tool setup occurrence time. The unit schedule Sch where the setup occurs is obtained from the output of the setup occurrence schedule search unit 48. The tool setup occurrence time is displayed on the screen together with each guide display 82 as shown in FIG. In this case, the first setup occurrence time display (the time “05/08 12:28” for the tool with the tool number “2” in the figure) is displayed on the screen. Also regarding the picking occurrence time, up to a total of three tools are displayed.

According to the tool setup time display device having this configuration, the earliest tool setup occurrence time is thus displayed as the tool setup occurrence time display 80 on the screen of the display device 47. Further, the tool setup occurrence time is a value calculated by the estimated time updated by the actual machining time by the actual result update means 93. For this reason, the tool setup occurrence time is easy to understand, and an accurate tool setup occurrence time corresponding to the actual machining time is displayed. In addition, as described in the flowchart of FIG. 4, since the current time is acquired and the prediction is calculated, even when an interrupt process is entered in the process schedule, the setup occurrence time is displayed correspondingly. . For this reason, the worker only needs to go to the punch press at that time, and wasteful work waiting time can be reduced.
Note that the control device 41 maintains the stopped state until the setup is completed when the unit schedule Sch in which the setup occurs is executed.
