Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a machining history management device for a plate material processing machine, which can display the executed NC program name in association with the number of executions, the machining start time, and the end time.

[0002]

[Prior Art]

 In the production management of plate processing machines, it is necessary to clearly know how much processing is currently completed for the plate for which processing is instructed, and how it is progressing in the field.

Conventionally, in the on-site management of a plate material processing machine, a work plan is referred to, a processing plan for one day is set, and processing is performed as planned, and the processing management has not been given much importance. However, it is possible to display only the history of how many pieces are currently processed.

[0004]

[Problems to be solved by the device]

 However, it is not possible to know what has been machined, etc. simply by displaying the number of machines processed as in the past as described above. If machining is proceeding as planned, that is fine, but there are some troubles and the line If there is a deviation in the production plan in part of the above, there was a problem that the plan of the entire line would be confused.

Therefore, the present invention manages the production state of the processing machine or the processing line to easily grasp whether or not the production is carried out according to the plan or whether the plan needs to be changed. It is an object of the present invention to provide a processing history management device for a plate processing machine capable of performing the above.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention constitutes a processing history management device for a processing machine as described in the scope of utility model registration claims.

[0007]

[Action]

 In the machining history management device of the machining machine of the present invention, it is possible to display the list of the executed NC program names in association with the number of executions (that is, the number of machining), the machining start time and the machining end time.

Since the processing statuses of all the processing machines in the line can be displayed in a list, it is also possible to aggregate these and display the production status of all the machines.

Thus, the production status of each machine or all machines can be known at a glance, and the subsequent production plan on site can be reliably and easily established.

【Example】

 FIG. 1 is an explanatory diagram showing an outline of a processing system embodying the present invention. In the figure, 1 is a punch press machine as an example of a processing machine, 2 is a CNC device for numerically controlling the punching machine, and 3 is an MMC (man / machine) that is connected to this CNC device and processes data editing and other operation information. Machine controller). The processing history management device of this example is configured in this MMC3. First, the CNC device 2 is connected to the punch press machine 1 and controls various actuators of the punch press machine 1 according to the input NC program or schedule data designating the execution order and the number of times of these programs. The control result is appropriately detected by sensors and output to the CNC device 2.

On the other hand, the MMC 3 has a processing history file 4 and a display control device 5 built therein. The MMC 3 monitors the actual operation of the CNC device 2, records the time when a new NC program is set after the NC device enters the machining start mode, and records the time at which each NC program is executed. Machining history memory that records the number of executions corresponding to each name and records the machining end time of each NC program so that if the same NC program appears later, the previous recording time is updated at a later time. Part, and the recorded contents of the machining history storage part based on the machining history display command, and for the NC programs that have been executed, the program name is displayed as a list of the number of executions, the machining start time, and the end time. Therefore, at a certain time, in order to issue a machining history display command, the machining is performed in the machining start mode, and the following list is displayed.

No. NC number Number of sheets Start time End time 1 O0100 2 10:25:30 10:42:05 2 O0155 5 10:51:25 11:10:23 3 O3222 3 11:40:48 12:01:18 The operator is By looking at the above display, it is possible to know the current production status, whether or not the plan is carried out as planned, or the deviation of the plan, and it is possible to easily make the next plan. Since the display also shows the start time and end time of processing, the time required for processing and the end time of the schedule for the next plan can be easily estimated, and a simple display allocation is possible. Can be used for multiple purposes.

The processing history can be managed not only for one day, but also for five days and ten days. In addition, the number of processed sheets of the day can be held by the content of the processing history and the number of processed sheets can be left as the number of products. The processing history can be displayed not only on the screen but also on the printer. The processing history file can be viewed on the host computer of the office not only by MMC but also by transfer or IC card. The present invention is not limited to these embodiments, but can be carried out in appropriate modes by making appropriate changes in design.

[0014]

[Effect of the device]

 As described above, since the present invention is the machining history management device for the machining machine as described in the scope of utility model registration, the executed NC program is displayed in association with the execution count, the machining start time, and the end time. It is possible to understand the amount of work per day, the working rate of work, etc. at a glance by the working history. In addition, they can be used for progress management, and production plans can be made easier.
