BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation data collecting / calculating device for collecting operation data of a machine tool such as a press machine and performing a predetermined calculation based on the data.

[0002]

2. Description of the Related Art Conventionally, in the case of managing the operating data of a processing machine, in a small factory or a single machine, the worker generally records the operating time and the production quantity in a daily report as data and manages them. Was. In addition, in the case where the production quantity is large or there are many machines to be managed, etc.
As disclosed in Japanese Patent No. 26093, a data collection device using a personal computer is also used. Further, in a factory where a so-called FA system is introduced, or in a CAD or CAM system designed and manufactured by more advanced computer control, all necessary production information is computer-managed.

[0003]

In the case of the above-mentioned conventional technique, when the worker writes and manages in the daily report,
The number of man-hours required for time management and reading and resetting of machine counters was troublesome, and mistakes were prone to occur. Further, the management using a personal computer is extremely expensive as a system provided for a small-scale factory or a single processing machine, and an effect commensurate with the reduction in man-hours cannot be obtained. Furthermore, the so-called F
A system, etc. is not profitable at all unless it manages a large number of machines from the price.
Even from its processing capability, it is an excessive facility as a system for managing a single machine.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to reliably collect the operation data of the processing machine with a simple and inexpensive device, perform a predetermined calculation and display it. It is an object of the present invention to provide an operation data collection arithmetic unit capable of performing the above.

SUMMARY OF THE INVENTION According to the present invention, a programmable logic controller is provided which receives data on the operating time and processing time of a processing machine and performs a predetermined calculation based on the data, and is integrated with the programmable logic controller. It is an operation data collection arithmetic unit provided with a printer which is provided and prints the above-mentioned data and the above-mentioned calculation result. Further, the programmable logic controller and the printer are housed in one case body.

[0006]

The operation data collection arithmetic unit of the present invention inputs the operating time and the processing time data of the processing machine to the programmable logic controller, and based on this data, the operating rate and the processing rate etc. by the programmable logic controller. Is calculated and the data such as the operating time and the calculation result are printed and displayed by the printer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The operation data collection arithmetic unit of this embodiment is attached to a processing machine 10 that performs press working, and includes a known programmable logic controller (hereinafter abbreviated as PLC) 12 and a printer 14 that prints the output of the PLC 12. Provided with this PLC12
The printer 14 and the printer 14 are housed in one case body 16. The PLC 12 may be inexpensive and small in size, and may be one for well-known one-machine control. A carrying handle 18 is attached to an upper surface 16b of the case body 16, and an output section 20 of the printer 14 and a power switch 22 are provided to the front surface 16a. Further, the entire surface 16a is provided with a lamp 24 for displaying the operating state of this device and a reset button 26. A terminal 28 for collecting data is provided inside the case body 16, and a cable (not shown) is pulled out from the back surface of the case body 16.

The data input to the PLC 12 is a control signal for turning on and off the motor and various valves of the processing machine 10. By turning the control signal on and off, time is counted and the number of times is counted. Is taken in as data.

Next, the processing contents of the operation data collection arithmetic unit of this embodiment will be described with reference to FIGS. First, when the operation of the processing machine 10 is started, the processing during the operation is started, and the counting of the number of times of operation N1 and the integration of the operation time T1 are started. The number of operations N1 is the number of times the operation of the processing machine 10 is started after the operation is stopped. At the same time, for each machining type of the machining machine (machining A, machining B, etc. in FIG. 3), counting of the machining times NA, NB, etc. and machining time TA, TB, etc. for each machining are started. Then, this processing is performed until the predetermined data collection deadline time comes. Then, when the predetermined data collection deadline is reached, the above-mentioned data collection is stopped and a predetermined calculation is started based on the collected data.

Further, when the operation is stopped, as shown in FIG. 3, the processing during the stop of the processing machine 10 is started, the number N2 of the stop is counted, and the stop time T2 is integrated.

As shown in FIG. 4, the arithmetic processing calculates a total time T from the previous collection deadline time to the current collection deadline time of this operation data collection arithmetic unit, and at this total time T, the integrated operation of this time is performed. The operating rate K1 is obtained by dividing the time T1. And processing time TA, TB
Etc. are each divided by the operating time T1 to obtain the processing rates KA, KB, etc. After that, the printer 14 receives these data N
1, T1, N2, T2, NA, TA, NB, TB, K
Print 1, KA, KB, etc.

According to the operation data collecting / calculating device of this embodiment, the processing data can be surely collected and calculated by a simple device, and the man-hours can be reduced by the inexpensive device. It also enables efficient operation and management of a single processing machine.

The operation data collection arithmetic unit of the present invention is not limited to the above embodiment, the types of various data can be selected as appropriate, and the arithmetic contents can be programmed appropriately.

[0014]

The operation data collecting and calculating method of the present invention is
Using a programmable logic controller, it is possible to easily collect and calculate the operating data of processing machines.
Moreover, since the printer is integrally provided, it is easy to handle. In particular, by accommodating the programmable logic controller and the printer in one case body, mounting and carrying becomes extremely easy. Further, the cost is low, and it can be easily attached to a new processing machine as well as to an existing processing machine. In addition, programming such as predetermined calculation is easy, and it is easy to install it in a small factory or each individual machine, and the cost performance is high.
