Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a utilization rate totaling device for facility equipment.

[0002]

2. Description of the Related Art In every manufacturing industry from electronic component manufacturing to device manufacturing, various automation equipments are put in to improve the manufacturing efficiency and endeavor to increase the operation rate of these automation equipments. With the transfer of production to Southeast Asia and China, that is, the hollowing out of domestic production, further improvement in efficiency of domestic production is being called for. Under such circumstances, manufacturing companies are actively working on the proposition of how to improve the operating rate of automated equipment by grasping the operating state of their equipment.

The first step to improve the operating rate of equipment is to accurately grasp the operating status of each equipment. In other words, it is particularly important to make full use of the operation rate totalizing device having excellent responsiveness and accuracy to grasp the operation and failure time of each equipment and to study improvement measures.

The configuration of the operation rate tallying apparatus currently used is shown in FIG. 3 and will be described. The state input unit 2 is attached to each automated facility and the operating state is input at any time. For reference, if you write the method of inputting, the method of operating switches etc. by the operator, the operation information built in the equipment itself is RS-
There is a method of performing communication by communication such as 232C. The state data of the state input unit corresponding to n pieces of equipment is collected in the data integration unit 1 via the data collection unit 4 for each piece of equipment.
Time is accumulated for each state. For example, this is output as a form from the form output unit 3 into a facility-specific operation rate weekly report,
It is used as a material for examining the utilization rate improvement.

FIG. 4 shows a specific example of the configuration of the operation rate totalizing device shown in FIG. In FIG. 4, the status input unit 2
Will be described as an example in which a facility operator inputs a state data by pressing a switch representing three states of operation, stop (excluding a fault), and a fault, which corresponds to an operating state. Three-state data of each state input unit 2, for example, the number of equipment is 100
In the case of a stand, a total of 300 state data is collected in a personal computer (hereinafter referred to as a personal computer) which is a data integration unit 1 via a sequencer (programmable controller) used as the data collection unit 4.
The personal computer integrates each status data,
The stop time and failure time are output from the printer of the form output unit 3 as a form.

[0006]

However, in the above-mentioned conventional utilization rate totaling device, in order to improve the data accuracy, it is necessary to shorten the data collection interval, that is, the data sampling period (for example, to 1 minute). Yes,
The data integrating unit, for example, a personal computer always collects and integrates data, and the load on the personal computer becomes extremely heavy. Therefore, in the current device, for example, create high value-added data for improving the operating rate such as "output forms in order of high failure rate" or "output the operating rate of the specified equipment on the PC screen". Difficult to do.

Furthermore, when the data accumulating unit stops operating, the data of all the equipment is lost, and therefore measures for improving reliability such as duplication of the data accumulating unit and installation of an uninterruptible power supply are necessary. Become.

An object of the present invention is to provide a highly reliable operation rate totaling device which is capable of producing high value-added data and has high reliability.

[0009]

In order to achieve the above object, in the present invention, the state input unit is provided with a data integrating function, and the state input unit is provided with a data request from the data integrating unit (hereinafter referred to as "data request"). The integrated data is transmitted in accordance with (polling), and after the transmission is completed, the integrated data is reset to zero and the data is integrated again.

Further, preferably, the status input unit is configured to add the time from the previous polling to the current polling when transmitting the integrated data, and transmit the integrated data.

[0011]

According to the above construction, the data integrating unit only needs to receive and integrate the integrated data of the state input unit at regular intervals (for example, one hour), and the load is drastically reduced. As a result, the data integration unit can allocate time to create high value-added material for improving the operating rate.

Further, by adopting a method of transmitting data from the data integrating unit up to the polling interval, even if the data integrating unit fails, the operating rate is calculated from the integrated data of each state and the total time (polling interval) when the data recovering unit is restored. it can.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an operation rate totalizing device according to the present invention, and FIG.
Shows a specific example of the configuration of FIG.

In FIG. 1, the operation rate totalizing device is composed of a plurality of status input units 2 for inputting the operating status of each facility, a data integrating unit 1, and a form output unit 3, and a status input unit 2 Is composed of a status input unit 2a for taking in the operating status of the equipment and a data integration unit 2b for receiving data from the status input unit 2a and integrating the time. The operation of the operation rate totalizing device thus configured will be described below.

(Operation 1) The data accumulating unit 1 transmits a reset signal to all the state input units 2 when the operation rate totalizing device is started up (when the power is turned on, etc.).

(Operation 2) Upon receiving the reset signal, the status input unit 2 resets (zeroes) the integrated data of the data integrating section 2b to zero once, and then the data from the status input section 2a is transferred to the data integrating section 2b. Accumulate time.

(Operation 3) After that, the data integration unit 1
Indicates that each state input unit 2 has a predetermined fixed cycle.
The polling P1 for sequentially requesting integrated data is performed. (Operation 4) The state input unit 2 sends S1 the integrated data of the data integration unit 2b to the data integration unit 1. After that, the accumulated data is reset to zero and the time accumulation is started again. This is repeated for the number of state input units 2.

As described above, the integrated data for each fixed time of each equipment, that is, the operating time is collected in the data integration unit 1, and the equipment operating rate is totaled. This is edited into a form such as a weekly report and the form is output from the form output unit 3.

A specific configuration example of the operation rate totalizing apparatus shown in FIG. 1 will be described with reference to FIG. In the embodiment shown in FIG. 2, a personal computer is used as the data integration unit 1, a printer is used as the form output unit 3, and the status input section of the status input unit 2 operates
The figure shows a case in which an operator operates a switch to operate any of the above three states of the relevant equipment, which is composed of three switches, that is, a stop (other than failure) and a failure. In FIG. 2, only one state input unit 2 is shown for ease of explanation. The operation rate totalizing device shown in FIG. 2 also operates in the same manner as in FIG. 1 described above, and can collect operating time integrated data, stop (other than failure) integrated data, and failure time integrated data of each facility at a fixed time interval on a personal computer. Yes, the required forms can be output via the printer.

In the operation rate totalizing device shown in FIGS. 1 and 2, for example, if the data collection interval of the data integration unit 1, that is, the polling interval is set to 1 hour, the data integration unit will be sent from the status input unit 2 once an hour. All you have to do is add up the collected data. Therefore, the data accumulating unit 1 is to improve the equipment operating rate such as "reporting the operation rate of the designated equipment on the data accumulating unit 1 (personal computer)" most of the time. It can be used for editing data of, and can be more effective as a tool for improving the operation rate.

Further, in the operation rate totalizing device shown in FIGS. 1 and 2, when polling from the data integrating unit 1 to the status input unit 2, the status input unit 2 not only collects the status integrated data but also collects data from the previous polling to the current status. If the cumulative time until polling is also added as transmission data, a highly reliable operation rate totaling device can be provided as follows. In other words, if the data accumulating unit 1 with low reliability of continuous operation such as a personal computer is used, and if it should fail, all the data necessary for calculating the operating rate remains in the status input unit 2. Therefore, by adopting the method of reading all the data of the status input unit 2 when the personal computer returns to the normal state, the target operation rate can be calculated.
