Abstract
Abstract In a method of sequence control for controlling a production installation containing one or more functional units independent of brand and process of product to be produced, unit sequence programs are provided for each of the functional units. A series of steps from start process to a stop process are installed for every minimum function unit which are independent of brand and process of a product to be produced. Sequence control is performed by enabling and disabling the selected unit sequences automatically or manually, so that the functional unit is controlled by the parameter stored in the unit sequence program.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
125 words
A method of sequence control for controlling unit sequence programs singly or in parallel, each of the programs including a series of steps from a start process to a stop process and each of the programs being installed for every minimum function unit which is independent of brand and process of product to be produced, the method of comprising the steps of: controlling a unit sequence program in association with at least one program selected from other unit sequence programs and other control programs; preparing unit sequence programs for each of the minimum function units, each of said unit sequence programs availing itself of operating conditions of each production as parameters and controlling each minimum function unit with sequence control in accordance with the parameters.
Claim 2
Independent Claim
125 words
A method of sequence control for controlling unit sequence programs singly or in parallel, each of the programs including a series of steps from a start process to a stop process and each of the programs being installed for every minimum function unit which is independent of brand and process of product to be produced, the method of comprising the steps of: controlling a unit sequence program in association with at least one program selected from other unit sequence programs and other control programs; preparing unit sequence programs for each of the minimum function units, each of said unit sequence programs availing itself of operating conditions of each production as parameters and controlling each minimum function unit with sequence control in accordance with the parameters.
Claim 3
Dependent Claim
55 words
The method of sequence control according to claim 1, wherein said unit sequence program further comprises at least one flag which is related to at least one program selected from the other unit sequence programs and other control programs, whereby the unit sequence program can progress in response to the state of the respective flags.
Claim 4
Independent Claim
44 words
The method of sequence control according to claims 1 or 2, wherein said unit sequence program is controlled by an operation scheduler having the parameter which is a stepping condition or the information with respect to the unit sequence to start or to stop.
Claim 5
Dependent Claim
60 words
The method of sequence control according to claim 3, wherein at least one unit control device, each of which performs sequence control of at least one brand by taking necessary operating conditions for the brand as the parameters in the unit sequence program, is controlled by a central control device and the parameters are set by the central control device.
Claim 6
Dependent Claim
21 words
The method of sequence control according to claim 4, wherein one unit control device controls processes of a plurality of brands.
Claim 7
Dependent Claim
75 words
The method of sequence control according to claim 5, wherein entry counter numbers which show the order of using said unit sequence program and the operation parameters are stored in a storing means in the central control device, and the entry counter number is designated in the unit sequence program, in the case where the same unit sequence program is used a plural number of times for producing the same brand or a different brand.
Claim 8
Dependent Claim
43 words
The method of sequence control according to claim 5, wherein the central control device monitors the brands, lot numbers, stage numbers of the executing process, conditions of start, stop and complete of the unit sequence programs in a memory of a control computer.
Claim 9
Dependent Claim
75 words
The method of sequence control according to claim 7, wherein entry counter numbers which show the order of using said unit sequence program and the operation parameters are stored in a storing means in the central control device, and the entry counter number is designated in the unit sequence program, in the case where the same unit sequence program is used a plural number of times for producing the same brand or a difference brand.
Claim 10
Independent Claim
164 words
A method of sequence control for controlling unit sequence programs singly or in parallel, each of the programs including a series of steps from a start process to a stop process and each of the programs being installed specifically for every minimum function unit of an apparatus which is independent of brand and process of a product to be produced, the method comprising the steps of: providing unit sequence programs for each of the minimum function units to be able to operate in association with at least one program selected from other unit sequence programs and other control programs; inputting the operating condition for each brand as parameters into each of the unit sequence programs; controlling, by means a central control device, at least one unit control device for controlling at least one unit sequence program for at least one of the brands in accordance with the inputted parameters; and setting the operating conditions for the minimum function units through the central control device.
Claim 11
Independent Claim
