JPS58163005A - Sequence controller - Google Patents

Abstract

PURPOSE:To realize a multi-purpose application of a sequence controller with a simple device, by adding functions which are not contained in a sequencer programming console to a programming console unit connected to a sequencer and then using these functions with switching. CONSTITUTION:A CRT unit 10 contains an original function (1) of a programming console of a sequencer 9 which controls the operation of a stacker crane 8 of a machine device such as an automatic warehouse. A monitoring function (2) for monitor, fault display, etc. of the working state of the crane and a function (3) for input/output setting of warehouse and its data display are added to the unit 10. A keyboard 11 contains the keys for additional functions (2) and (3) and a key which switches the functions (1)-(3) in addition to a key exclusive for the original function (1). As a result, it is possible to select and use occasionally each type of functions which have a small frequency of application in addition to the original function. Thus, the cost of equipment is reduced.

Description

[Detailed description of the invention] The present invention relates to a sequence control device.

When using a sequencer to control a mechanical device consisting of
As shown in FIG. 1, in addition to the sequencer 1 and the mechanical device 2 to be actually controlled, a setting device 6 for setting control conditions and data for the mechanical device 20, and a display device 4 for monitoring operating conditions, alarms, etc.
, various selection switches, changeover switches 5, etc. are often used in combination.

In such a case, even when a type using a CRT7 is used as the programming console 6 of the sequencer 1, the CRT unit is used as a single function function as the programming console of the sequencer 1, and the settings as described above are used. The device 6, display 4, switches 5, etc. were connected to the sequencer as separate units.

The present invention aims to make effective use of the CRT unit and significantly reduce equipment costs by providing various functions other than the function as a programming console to the CRT Unisol sequencer. be.

An embodiment of the present invention will be described below based on FIGS. 2 and 3. For example, a stacker crane 8 in an automated warehouse.
The original function of the sequencer 9 as a block ramming console which controls the operation of The keyboard 11 has a setting and data display function (■), and in addition to keys 12 dedicated to the sequencer/programming console, the keyboard 11 includes keys 15 for executing the additional functions (■ and ■), and a key 14 commonly used for both functions. and a J8B key 15 for switching to a mode for selecting functions 1 to 2.

When programming the sequencer 9, after operating the JδB key 15 (use the numeric keypad to select the original function ■), then use the keys 12 and 14 to program the sequencer in the same way as before. When actually operating the car crane δ, select the function ■ by the same function selection operation as described above, and use the keys 16 and 14 to set the loading and unloading settings.At this time, the CRT unit 10
Setting data is displayed on the CRTloa.

When the loading/unloading settings are completed and the stacker crane 8 is to be operated, the operating status of the crane will be displayed on the CRTloa of the CRT unit 10 by selecting function ① using the function selection operation described above, and the operating status of the crane will be displayed and the abnormality detected. When a situation occurs, it is also displayed.

As described above, according to the sequence control device of the present invention, the programming console CRT unit connected to the mechanical device control sequencer has [7 device control condition setting and display functions, mechanical device operating status, failure diagnosis, etc.] In addition to adding a display function and other functions other than the sequencer/programming console function, we also provide a means to switch these functions. CRT units for programming consoles, which were very rare, can now be used effectively as conventional setting devices and displays, and external devices such as setting devices and displays are no longer required, or As a result, we have been able to achieve significant cost reductions in equipment costs.
