Definitions

  • the present invention relates generally to control systems for controlling various events that are performed repetitively and sequentially to manufacture large numbers of discrete products.
  • molten glass or hot glass gobs are delivered from a feeder through a distribution system and are delivered to a plurality of independent sections sequentially into upwardly opening blank molds in each of the sections.
  • Each mold section is a self-contained unit which includes a blank molding station and a blow molding station.
  • the molten gob of glass is sequentially delivered to each section of the machine and is transformed into a finished bottle in two stages, respectively, in the blank molding station and in the blow molding station.
  • Each bottle-forming section of the glassware-forming machine is identical in construction and the sequence of events for each section must be accurately controlled on a repetitive basis for each section.
  • the present invention provides a redundant data processor control system for a glassware forming system which provides a high degree of protection against breakdown or malfunction of the control system.
  • two data processors are utilized and both processors are operating concurrently; however, only the output of one data processor is utilized to control the system at any given time. Hence, an operator can continually monitor the operating condition of both processors. It is important to note that both processors are actively operating to provide control outputs, but as mentioned above, only the output of one processor is coupled to the machine or machines to be controlled.
  • the sole FIGURE is a block diagram illustrating the inventive control system.
  • the inventive control system 10 comprises a supervisor subsystem 11 which controls both the bottle forming functions of one or more IS machines having multiple sections, and the machine data terminals.
  • the supervisor subsystem 11 includes a supervisor processor 15 such as for example, such as an DEC Mi ⁇ ro-11 computer (manufactured by Digital Equipment Corp.) which provides intelligence to the control processor subsystem 12 and controls 5 communication with the other components of the supervisor subsystem.
  • a supervisor processor 15 such as for example, such as an DEC Mi ⁇ ro-11 computer (manufactured by Digital Equipment Corp.) which provides intelligence to the control processor subsystem 12 and controls 5 communication with the other components of the supervisor subsystem.
  • the supervisor subsystem 11 When machine setup or timing functions are to be changed, the supervisor subsystem 11 translates the changes into a format acceptable by the central 0 processing subsystem 12 and then communicates this information to a control or central processors or .computers 17A and 17B.
  • Product data information is also controlled by the supervisor subsystem 11 so 5 that the user can create and maintain job setup information and product timing files. Active product files and all current timing information is stored on the system disks generally labeled 18.
  • the system printer 19 ° provides hard copy of the data in video screens are selected and generates selected reports.
  • the printer provides a permanent record of all management information reports and may also be used for hard copy output of video screen 5 information from the supervisors console terminal 14, such as a TI 820 (manufactured by Texas Instrument Co.) receiver terminal or similar device.
  • the operators terminals serve as consoles for the processor 15. These units may be a DEC VT 102 video terminal (manufactured by Digital Equipment Corp.) or similar device.
  • the operator terminals 16 allows the operator to accomplish job changes and to run the product timing functions and change them as required. The operator is also provided with a set of real time reports which allow him to monitor the performance of the machine.
  • the control subsystem 12 provides real-time control of the I/S glassware forming machines and also provides data acquisition for machine functions which data may be included in various reports.
  • the control processors 17A and 17B receive information/data from the supervisor subsystem 11 through suitable memory (RAM) boards generally labeled 21 and incorporates the data into the active control programs or into the machine timing tables as appropriate.
  • the control programs provide the necessary coordination of control to operate each section of the I/S machines generally labeled 30. It should be appreciated that the control system shown in FIG. 1 can be utilized to control one or more machines.
  • control program obtains information from each I/S machine as to the exact operating position or status of that
  • I/S machine This information is then transmitted through a suitable known cable splitter board 26 to the respective associated machine interface module 25. Information or data from supervisor subsystem 11 is concurrently received. Such input information may include machine operational data for reports and status or it may be a request for a special cycle initiated by the operator. These functions are executed asynchronously by the control processors 17A and 17B using user modifiable subprograms.
  • the timing signals for the control processors 17A and 17B may be provided as by a timing pulse transducer 32, such as a shaft encoder of any suitable known type which is mechanically driven from the shear cam shaft on the I.S. machine.
  • a shaft encoder can provide position indicating pulses at one degree intervals and a reset pulse at zero degrees.
  • the control subsystem 12 is fully redundant to insure continuity of control in the event of equipment failure.
  • the two identical control processors 17A and 17B are connected or coupled in the circuit and simultaneously or concurrently execute the control software program.
  • Processor 17A is termed the connected or in-line processor and the processor 11B is termed the redundant processor.
  • Processor 17B might be considered as the stand-by processor, however it should be understood that both processors 17A and 17B are concurrently executing the same program and commands.
  • the output from only one of the processors is electrically connected to the system, as indicated at 22A.
  • the 22A electrically may consist of an electronic switch means as is well-known.
  • the output from the other processor, as at 22B is disconnected.
  • each of processors 17A and 17B is monitored on each I/O cycle such as by well-known watch dog timers 28A and 28B; and, if a fault is detected in the coupled or connected processor, that processor is automatically uncoupled or disconnected and the other processor is automatically coupled or connected to the respective line interface unit 23A or 23B.
  • each of the control processors 17A and 17B may include electronic switching controls 20A and 20B of any suitable known type to connect and disconnect the associated control processors from the data control paths.
  • the electronic switching control means 20A include temperature sensors, and voltage sensors which provide an indication of the operating condition of the particular processor 17A and 17B. As stated above, both processors 17A and 17B are operating concurrently and in synchronism, an the operating condition of both processors is continually being monitored.
  • processors 17A and 17B are normally in operation, neither processor is on a .standby mode.
  • switching control means 20 disconnects or opens, and also the watch dog timer 28A cause electronic switch 20A to open and the output of central processor 17A is thus disconnected from the circuit. Also, switching control means 20A causes switching control means 20B and watch dog timer 28B also closes electronic swtich 22B and thus the output of central processor 17B is connected to the glassware forming machine or machines 30 without interrupting the operation of the machines.
