Description

The subject of the invention is a control system for a device for the production of glass products from molten glass, especially for electronically controlled individual components of devices for the production of glass products. Known devices for the production of glass products contain a group of components, each of which has devices for producing glass products in a time-controlled, predetermined sequence of control steps. Typically, the components are fed from a single source for molten glass, which forms the molten glass bodies, separated into individual components in a predetermined sequence. The subassemblies work synchronously with a relative difference of phases so that one subassembly receives information about the solid, while another subassembly gives information about the finished glass product to the feeder, and one or more other subassemblies perform various intermediate steps of manufacture. is a control system for an apparatus for the manufacture of glassware from United States Patent No. 3,762,907. Until now, this device has usually been driven by air motors or servo motors. The air motors were controlled by a valve assembly, which in turn was controlled by a timing drum for each component controlled by a shaft that synchronized all parts of the machine. One of the limitations of the timing drum was the difficulty of adjusting the timer while the machine was running. One of the known solutions to this problem has been the replacement of all the timing drums with electronic control systems. The electronic control systems include a master unit that operates in accordance with the signals of the clock pulse generator and the shaft-controlled reset pulse generator. The master unit generates reset signals for an individual control for each of the individual subassemblies to synchronize the operation of the individual systems. Each particular system includes a pulse counter responding to clock pulses, and the master unit generates reset pulses to count the steps of the cycle. Each individual system includes forty-eight three-decade switches on the wheels d) a "setting the degrees of rotation of the device. Hence, each particular function of the glass product cycle is controlled by one of the switches on the wheels. It is also known from US Patent 3,905,793. electronic control system that uses discrete elements in the circuits of the counter and logic combination elements. Later control systems use a digital computer with memory and a cooperating program. This type of control system not only implements the system of automatic change of time values. of the word functions without manual reset of the finger wheel switches, but also implements a circuit to programmed events, groups of corresponding functions according to 2 certain time-boundary events. The computer generates control signals through the interface to actuate the electromagnetic valve assembly agnesem. Control systems of this type are also disclosed in patents Nos. 4007028 and 4108623. The inventive system comprises a control computer connected to the output of a pulse generator, the output of which is also connected to the inputs N of the computers of the individual sections, which inputs are also connected to the control computer. and the N outputs of the computers are connected to the individual N sections. The control computer outputs are connected to an input / output circuit, a memory chip and a rejection control panel to which the reject station is attached. Connected to the second input of the individual station computer is an output material sensor, and to. the second input / output of the computer is an attached Section Operator Control with an output attached to the section and an input attached to a remote start and stop station. *; The individual section comprises a valve block, the output of which is connected to the mechanisms forming the glass product. The system according to the invention comprises a memory circuit for storing a program for controlling the manufacturing steps and for timing on and off to determine the pause time, a circuit responsive to control signals attached to the memory elements. components of the product and a system sensitive to the signals of the required change, attached to the system providing the control signals for producing signals representing the required changes of the selected value of on or off syncronization. The timing values are expressed in steps of the cycle of the device and the control system is sensitive to a signal of a change required to cause a change of one degree The system providing a change signal comprises elements of selection of elements producing glassware, selected elements of a timing value to produce a signal representing a selected timing value wl The on / off and increment / lapse items of the selected timing value. The product producing item selection circuit includes a function selection toggle, the selected timing value items contain an on / off selection toggle and the increment / lapse items include a downstream toggle and an earlier toggle, function selection toggle, selection toggle on / off, with the subsequent toggle and the prior toggle being connected to the product-producing element selection elements. The section operator console is linked to an individual section computer that reads the time change values and taps the corresponding previous time data with new data. The dwell time value is associated with each device function and indicates what portion of the device cycle is executed between on and off timings. A pause inversion occurs when the on value is moved beyond the off value or when the on value is shifted beyond the switch-on value for a particular device function.; -; Inverted * device function breaks * could cause mechanism collisions and break the jpo mode cycle. - 4 None of the known devices has circuits to prevent a break reversal. According to the invention, in a situation when an operator requests a time value change, a suitable individual selection computer automatically prevents the interruption of the pause and therefore eliminates the problems associated with interrupting the pause. The advantage of the system according to the invention is to increase the efficiency of devices for the production of glass and glass products, being individual sections, by preventing the reversal of the pause in the timing control of the mechanism. The subject of the invention is illustrated in an exemplary embodiment in the drawing, in which Fig. 1 shows a simplified block diagram of an apparatus being an individual section for the production of articles. of the glass and the control system for this device according to the invention, Fig. 2 - a more detailed block diagram of the control system and one of the individual sections of Fig. 1, Figs. 3h-8 - simplified program block diagrams which represent a part of the program being executed by the control computer of the circuit of Fig. 2 and Fig. 9H-12 - simplified program block diagrams representing a portion of the program executed by the computer of the individual section of FIG. 2. FIG. 1 shows a block diagram of an apparatus for the manufacture of glass products, which is an individual section in which the invention is used. the device receives a series of 30 timing pulses from the pulse generator 12 to establish a time program for the device cycle. The pulse generator 12 may be an encoder. The control computer 11 of the apparatus is connected 35 to a set of one to N computers of 13 individual sections, each of which is connected to a single section 14 working with it, one to a set of one to N sections of the apparatus for manufacture of glass products. Initially, the control computer 11 of the machine 40 feeds each of the section computers 13 with a control program and timing data to control a single section. Thereafter, each section computer 13 generates control signals in response to the control program and pulses from the pulse generator 12 to a valve block 45 (not shown) in the respective section 14 to control the glassware manufacturing cycle. The control computer 11 of the machine receives periodic current data from each computer of the 13 sections, which data can be stored for use next time in the production of glass products or in the event that one of the individual sections is shut down for any reason. 2 is a more detailed block diagram of the control system and one of the individual sections of FIG. 1. The pulse generator 12 generates a pulse train and feeds it to the machine control computer 11 and the section computer 13. The input / output circuit 15 and the memory circuit 16 are connected to the control computer 6 of the apparatus through a pair of bi-directional lines. The control computer 11 of the device and the computer of 13 sections may usually be high-integration computers, the input / output circuit 15 may be an ordinary teletype device and the memory chip 16 may be a regular memory chip on floppy disks. 122 800 5 The pulse generator 12 generates a clock signal For a control computer 11 and a computer 13, which signal produces a reference signal for controlling the machine cycle and the sequence of steps performed by the computer 13. Typically machine control is expressed in degrees, the machine cycle length being 360 °. Hence, 360 clock pulses or some multiples constitute the machine cycle. The cycle for each individual section is also 360 ° but the cycles for each section may be shifted relative to the beginning of the machine cycle by a different number of degrees to compensate for the difference in the feeding time of the element to each section. Pulse generator 12 produces a long reset signal of 360 clock pulses, which reset signal is used by computers 11 and 13 to determine the end and beginning of successive machine cycles. The control computer 11 is used to input control programs and time data. to the computer 13 from the memory chip 16. The operator uses the input / output circuit 15 to select individual time data to be input into the computer 13 of the sections. Note that each section computer 13 has a separate set of time data for the individual section it controls. Section computer 13 produces control signals for the valve block 17 via the section operator control 21 discussed below. The valve block 17 is connected to a plurality of mechanisms 18 forming the glass product to correct the molding steps in a specific time sequence to produce the glass products. The valves in the valve block 17 are actuated by electromagnets (not shown) which are controlled by signals generated by the 13 section computer according to the control program and time data which is continuously stored in the 13 section computer. The valve block 17 and the mechanisms 18 forming the glass product together form individual sections 14. Fig. 2 also shows a starting material sensor 19 which produces a signal upon detection of a body in the form of an individual section. The exit material sensor 19 consists of an exit material detector (not shown) to produce a signal for the section computer 13, which signal is used to adjust the timing of that individual section to the presence of a body, rather than to a separation time position, As has been done heretofore. The section operator control 21 is connected to the section computer 13 and the valve block 17 and is used by the operator to make adjustments to the timing of the mechanism. The actuation of the individual valves may be switched on or off by the operator using the control 21. The control 21 may also be used to change the section offset value and the reject timing value as will be discussed. Control 21 may be provided with an indicator (not shown) which makes it easier for the operator to check the current timer value for the individual machine functions. Control 21 is provided with a rotary function selector (not shown) to select a particular function. device function to regulate the time control. An on / off switch (not shown) is provided in the control system 21 to make corrections to the timer value or the off time value of the selected device functions. The control unit 21 is also provided with an "earlier" type spring-return switch (not shown) to accelerate the time values towards the acceleration of the cycle, and a "later" type spring-return (not shown) to delay the time values. If the operator requests a time value change, he first selects the individual device functions on the function selector and then selects an on or off time value on the on / off switch as required. He then depresses the acceleration switch if he commands the acceleration of the time dependency or the delay switch if he requires a time delay. As long as the operator presses the acceleration or deceleration switch, the station computer 13 automatically lowers or raises the time values one degree at a time. When the time value reaches the set level, the operator releases the depressed switch. Note that the section does not need to be in the off state when adjusting the timer, because the mechanism operation time value may be changed when the section is in the Run state. As discussed previously, each operation of the device may have a single on time value and one off time value. The value of the controlled break in device operation indicates that part of the machine cycle between the on and off values during which a particular function of the device is turned on. Hence, if the machine cycle is 360 °, a 0 ° gap value indicates that the function is being performed continuously. If the operator requests to change the time value of a function, it cannot be changed so that the enable value is implemented after the disable value and the disable value is implemented after the enable value. This type of steer-gap variation is known as steer-gap inversion, and could result in mechanical collisions that would break the molding cycle. According to the invention, the 13-section computer does not allow the device to be switched from 0 ° to 359 ° or 359 ° to 0 °. The control system 21 is also used to control the operation of an individual section. When an individual section is not running, it is referred to as a "safe" state. If the section is in a safe state, the operator can switch to a manual mode in which the solenoids in the valve block 17 can be controlled by a set of switches (not shown). used in the control system 21. Although the control system 21 is implemented with a start and stop control, it is located on one side of the device and is only easily accessible to the operator when the operator is on that side. The remote start and stop station 22 is usually located on the opposite side of the control system 21. Thus, the start and stop controls are easily accessible to the operator from both sides of the machine. The bottle reject control panel 23 includes a set of switches (not shown) each corresponding to a particular dimple of the mold of each individual section. If the operator is asked to reject a particular glass product, he activates the appropriate switch in panel 23. The control computer 11 periodically checks the panel 23 to determine if any switch has been actuated. When the control 11 detects an actuated switch, it will compare the rejection timing value * according to the rejected glass product section with the current position of the device. If the two values are equal, a rejection signal will be given to the bottle rejection station 24 so that the corresponding bottle (s) are rejected. As discussed previously, in connection with the timing of the valves, the operator may use the control system 21 to adjusting the timing value for the individual section so that the glass product from the selected mold cavity is rejected when it reaches the bottle rejection station 24. The reject timing value is stored in the 13-section computer as a machine cycle item. In a predetermined period, typically every minute , the control computer 11 reads the reject timing values of the 13 section computer and stores them. Each time the machine position changes one step, the control computer 11 compares the new machine position with the reject timing values and produces a reject signal when they match. 13 sections and a control computer 11 and between the control computer 11 and the I / O circuit 15 can be achieved using a model DLV11 serial I / O board (not shown). The input and output control for the section computer 13 for the control system 21 and the valve block 17 and for the control computer 11 for the bottle rejection control panel 23 and the bottle rejection station 24 may be realized by using the DRVII model of the parallel interface plates. input / output (not shown). If flexible disks are used as the data storage device 16, an RXV11 flexible disk driver (not shown) may be used to control the transfer of data between the control computer 11 and the flexible disk assembly, where all the DLV11, DRV11, and RXV11 chips are manufactured by the Digital Eauipment Corporation in Maenard, Massachusetts. As previously mentioned, the machine control computer 11 and the individual section computer 13 may be ISI-11 computers. As will be discussed, the features of this computer are automatic restart after a power failure and user control of an external task list. Figs. 3-8 show simplified flowcharts of the programs used in the operation of the machine control computer 11. As shown in Fig. 2, the control computer 11 is connected to an input / output system 15, which may be a teletype having a keyboard input and a printer output, and to a memory device 16 which may be a set of flexible disks. The memory chip 16 stores on flexible disks the data of both systems, such as control programs and job histories, which contain the time data for the formation of each type of glass product. The control computer 11 can be loaded by various "keyboard" programs from the panreboard 16, which programs allow the operator of the machine to place, change, list or delete job histories in memory or list the addresses of all stored job histories or transfer histories from one floppy disk to another, set the device parameters for the new job, input the job history to the computer of 13 sections from memory chip 16, keep the job history active by loading it from the computer, 13 sections, to the memory chip 16, reload kcnruter 13 sections threshold amem control and control data from any other 13 section computer or test pattern, display or change the number of cycles in which glass products are rejected. The main program for the control computer 11 is shown in the block diagram in Fig. 3. The program is started in the circle "start" and then enters the decision point "keyboard program task" to check that keyboard control wishes 25 have been entered by the machine operator. . If there is such a task, the program branches to the processing point. The processing point "execute assigned program from the keyboard" corresponds to a set of instructions telling the control computer to execute the program. The program then returns to the start of the main program. If there is no keyboard task, the main program branches from decision point to "no" and returns until the start of the program. It should be noted that all keyboard programs execute with the lowest priority and may be interrupted by any of the programs shown in Figs. 4-8. In addition to the keyboard programs initiated by input / output 15, control computer 40 11 is also responsible for executing other programs, all of which take precedence over keyboard programs. The interrupt program has the highest priority and is shown in the diagram of FIG. 4. A timer interrupt is generated each time a time pulse is received by the control computer 11 from the pulse generator 12. If the control computer 11 executes the program When a keyboard interrupt is generated, the keyboard program is interrupted and a timer interrupt is handled before the keyboard program returns. The timer interrupt program is started in a circle with the label "timer interrupt" and then proceeds to the processing point "device position counter increment 55" to update the overall count representing the device positions in the device cycle. The program then proceeds to the processing point "check the state of the reject control switches ** per section" which 60 includes instructions for checking the state of the reject control switches in the bottle reject control panel 23 in Fig. 2 per section. The program proceeds to the "any discard switches" selection point. to determine if any bottles were intended for rejection. If any of the recoil control switches 122 800 9 is activated, the program splits "yes" to the "device-reject" decision point, where the control computer 11 compares the current total device position count with the discard timing value. for each individual section. If they are equal, the program splits "yes" to the "discard marked bottle" processing point, which contains instructions for generating a reject signal for the bottle reject station 24 of FIG. 2 so that the intended bottle will be rejected. The timer interrupt program then returns to the main program to the point where the main program was interrupted, as is the case where the program branches to "no" from the decision point "any reject switches" when no switches are activated or when the program splits at the "no" point from the "device-reject" decision point, when the total device position count does not equal the reject sync value, the zero-interrupt program has a second priority priority as shown in Fig. 5. Each time a reset pulse is produced by the pulse generator 12, the reset program is started in the circle "restart restart interrupt". The program proceeds to the processing point "restart device position counter to 359", which contains instructions for breaking the total countdown. fixture position at the end of each fixture cycle The Zero Interrupt program then returns to the main program mu at the point where it was interrupted. After that, a pulse will set the counter to zero and 359 more pulses will be counted to complete the machine cycle. As the counter accumulates the last pulse, the reset pulse is re-generated to correct any errors that may appear in the overall position counter of the machine. As discussed previously, the operator can change the section timing data using the control 21. Approximately every 5 minutes the control computer 11 executes a stored program to update the current section timing data for each individual section, which is stored on the flexible disks in memory chip 16. Therefore, if the operator has changed the timing data for a section by accelerating or delaying the actuation of the valve, the timing change will be stored in the memory 16 in no more than five minutes. The control computer 11 is equipped with the control of an external schedule of tasks. For example, the operator may predict the execution of the program at absolute time of one day, delta time from synchronization clock units), or every few time units like five minutes. Hence, every five minutes the stored program is started in the circle "data update interrupt" and goes to the processing function "get the time data from the section computer and put it in the memory". After saving the current time data, the program returns to the main program. In Fig. 7 there is shown a rejection program which is executed by the control computer 11 approximately every minute to update the reject timing values. Hence, if an operator has changed any of these values to obtain a more proper rejection, the change will be remembered by the control computer 11 in no more than a minute. The reject program is started in the "discard update interrupt" wheel and passes to the processing functions, get the value Synchronize 5 rejects from the section computer and remember "which contains instructions for reading and remembering the current reject timing values for each campus selection. The reject program then returns to the main program. The stored values are used in comparison to the device position performed at the "device = discard" decision point of Fig. 4. If a power outage occurs, the contents of the computer register will be lost. Shown in Fig. 2 is the 15 block diagram of the program that it shows. steps taken by the control computer upon noticing a power failure. The control system 11 may be programmed to execute a restart program which is initiated in a "start" wheel. Then the processing function, play the logic and job history in each computer of the section "recreates the memory with the control programs and time data that were loaded before the power outage 25. The restart program then returns to the main program. 9-12 show flowcharts of programs that represent the operation of section 13 computer The main program is shown in Fig. 3. After the control computer 11 restores the memory of the section computer 11, the section computer 13 performs several control program initiation tasks. such as setting the machine position counter to 359. The main program is started in the "start" wheel and proceeds to the "block interrupts and execute initiation tasks" processing function which includes instructions to check the control system 21 to determine if the operator has requested changes to time data. section offset values or sync values by darts. A more detailed block diagram of this program is shown in Fig. 12. All requested changes are stored in the memory of the section computer 13 to be sent by the control computer 11 to the memory chip 16 during the execution of the memory program of Fig. 6 by the control computer 11. Then the main computer program The 13 sections proceed to the "enable interrupts" processing function, which contains instructions to enable the computer of the 13 section to respond to the pulses and breaks generated by the pulse generator 12. The program then proceeds to the decision point "communication task by the control computer". "11. If the control computer 11 requests data transmission 55 or receiving data from the computer 13 of the section, the program branches at the" yes "point to the processing function" transmit or receive data "which contains given instructions for communication between the control computer and section computer. The program returns almost step by step to the function "startup subroutine - change timer function" and continues the loop. If the control computer 11 requested communication, the program branches from the decision point "communication task by control com- puter" at point "no" to return to the first processing function.1228 * 011 The flowchart of the timer interrupt program for the station computer is shown in Fig. 10. Each time a pulse is received from the pulse generator 13, the main program starts the timer and stops it. reset, the station computer s initiates the timer interrupt because the timer interrupt program has a higher priority. The timer interrupt routine is started in the "clock interrupt" circle and passes to the "ignore clock interrupt" decision which checks the direction of the timer interrupt ignore As will be discussed later, the last c so that at least one timer interrupt is ignored, so that the program branches to "yes" and returns to the main program. If the timer interrupt is not to be ignored, the program branches to "no" and goes to the processing function "increment the device position counter "which includes instructions to update the total state of the counter representing the positions of the device in the machine cycle. As discussed above, this total count is preferably zero to 359 °, representing 360 ° in the machine cycle. This corresponds to one revolution of the time drum according to the previous embodiment which used cams to actuate the valves to actuate the glassware making apparatus, the position of the cams being defined in degrees. The program then proceeds to the "subtract section offset" processing function, which contains instructions for subtracting the section offset value, if any, from the total device position counter to obtain an integer count representing the instantaneous 35 positions of an individual section in the device cycle, which is total. the state of the counter is stored. The program then proceeds to the processing function "check switches for control plant state changes" which includes instructions to check the state of the start and stop switches on the control 21 and the remote control panel 22 to determine if the operator device state changes. The program proceeds to the "run" decision point to check that the section is in the process of forming glassware. If the section is not running, the program branches "no" to the "start start" decision point to see if it switches The start switches were triggered as determined by the processing functions. "Check the control state changeover switches 50". If the start switch has not been activated, the timer interrupt program splits "no" to the "repeat timer interruption" decision point. As will be discussed below, an early reset 55 pulse will require at least one additional timer interruption. so that the program splits "yes" back to the processing function "increase the count of the devices position *". If the interrupt of the clock is not repeated that the program is splitting on then "to return to the main program for waiting. to the next pulse. If the start switch has been triggered, the program splits to "tale" back to the "start" wheel of the main program to run the section. 65 12 If the section is running, the program divides from "work" to "yes **" to the decision point "Start stop" to verify that any of the stop switches has tripped as determined by the processing functions "check switch and change of state ". If any stop switch is triggered, the program splits from "yes" to the "stop sections" processing function, which includes instructions for stopping the section run. The timer interrupt program then enters the decision point "repeat timer interruption". If no stop switch has been actuated, the program splits "no" into the processing function "get the value in degrees next function from the table" which contains instructions to look for the value in degrees of the next forming function of the glass product to be performed in the table, where the forming functions are listed in the order in which they are to be performed in the forming cycle. The program then enters the decision point "position-degree ", where the instant position counter for a section is compared with the value in degrees of the next function to be performed. If the values are not equal, the program splits at the point "no" and enters the decision point "repeat interrupt clock *". If the values are equal, the program splits into "yes" and enters the processing function "do function ", which contains instructions to generate a control signal to the solenoid to actuate the correct valve in valve block 17. Then the program goes to the processing function" go to next function in table "which contains instructions to move to the next function in the table, yes that the degree value for this function is obtained when the program returns to the processing function "get the degree value of the next function from the table". Hence the program will execute all functions having the same degree value before returning to the main program. The reset interrupt is shown in Fig. 11. Each time the pulse generator 12 produces a reset pulse, and the main prime. The program allows the clock to be interrupted and reset, the 13-section computer initiates the interrupt reset program, which is started in the "interrupt reset" circle. The program then enters the "self-synchronization" processing function, which includes instructions to check whether the reset pulses have occurred between 359 ° a 0 "and if not present no further action is required. If reset pulses have occurred in the range of, for example, 357 * to 2 °, the instructions to modify the state of the clock pulse counter are executed. If the reset pulse was early, the next time the timer is interrupted, the timer interrupt routine will cycle as many times as required to increment the clock counters to synchronize the sections. If the reset pulse was late, the timer interrupt is ignored as many times as required to maintain the clock pulse counter for synchronization. "In these examples, the reset interrupt program then returns to the main program. If the zero pulses are out of range, a delay stop number 8oo 13 14 is initiated. The reset interrupt is lower in priority than the clock interrupt. There is also a program. line breakout, which is similar to the reset break program in Fig. 11. The break is produced by each cycle of the AC power source for the section commuter. Every specified number of cycles the line break program checks the state of the clock pulse counter to see if it has increased on since the last such check. If the clock counter 10 has not increased for a certain number of such checks, a stop is immediately initiated. In Fig. 12 is shown in the computer subroutine flowchart of the section "function timer change" that is entered into from the main program IT comp uter of the section in Fig. 9 in the "start" circle. As previously discussed, this subroutine contains instructions for storing all changes to the time data given by the operator. The first step is a "function change task" decision point which checks the control system 21 for signals indicating that the machine operator has requested changes to time data, section offset value or discard timing value. If a function change was not requested, the program branched out. to "no" and returns to the main program. If a function change is requested, the program splits "yes" to the "change time data" decision point to check for the change of enable or disable values required for the selected function. If the machine operator has not requested a change in timing data, the program splits "no" to the "reject or offset change" decision point to determine if the requested change is for one or two values. If such a change was requested, the program splits "yes" into a "write new value in degrees" processing function, which includes instructions to increase or decrease the discard timing or the offset value in degrees. Since both the discard timing and the offset value are single values, there is no timeout associated with them and there is no need to check for a possible pause reversal. If there is no task of changing any of the values, as in the case of a task without pressing the acceleration switch or delay, the program branches from "change reject or shift" no "back to the main program. If the machine operator requested changes to time data, the program branches from" change time data "to" yes "to processing function" send " switch-on = pause ". This function processed includes instructions for subtracting the on time 55 of the selected device function from the off time to obtain the pause time for the function. The progeam then enters the decision point "break = 0". If the branch is "yes" to the section of the program that # only allows the time control to be changed to the extension of the runtime. If the pause time is greater than zero, the program splits into timer change "no" to either narrow the pause time to a minimum of zero or extend the pause time to a maximum of 359 °. The "yes" trace leads to the M Timing, Off or On decision point. "to determine whether the operator of the machine has requested a change to the timer value for off or on. If a change to turn on has been requested, the program splits" no "to the decision point" faster start. " having an acceleration switch. If an acceleration switch is pressed by an operator, the program branches "yes" to the section of the program that starts with the processing function "block interrupts" for changing the time value, since such a change would extend the pause time above zero. Acceleration is not pressed, the program varies "no" from "faster switch actuation" to the processing function "indicate invalid change". This processing function instructs the control to produce a visual indication that no change is allowed because the acceleration switch is not pressed or the deceleration switch is pressed and such a change would invert the pause. The program then returns to the main program. If time changes are requested off, the program varies from the decision point "on or off time" at "off" to the decision point "trigger switch later". If the delay switch is pressed, the program branches from "yes" to the processing function "disable interrupts" because One change would extend the pause time above zero. If the delay switch is not pressed, the program branches on "no" to the processing function "indicated change not allowed" to indicate that no change is allowed, because the pic delay switch is depressed or the acceleration switch is if pressed and such a change would invert the pause. The program then returns to the main program. If the pause time is not zero, the program branches on "no" from "pause = 0" to the decision point "negative pause" to check the sign of the pause time If the break value is negative, indicating that the on value precedes a change from 359 ° to 0 ° in the cycle and the off value follows this change, the program branches off at "yes" to the processing function "add £ 60 ° to the gap that includes instructions for adding a 300 ° gap to obtain a positive gap time value. The program then goes to the decision point "gap = 359 °". If the pause time is already positive, the program branches "into" no "from the decision point" negative gap "to the decision point" gap = 359 ° ". If the pause time is not is equal to 359 °, the program branches "no" from the decision point "gap = 359 °" to the processing function "block interrupts" because such a timeout can be extended or narrowed. If the outage time is 359%, the program taps "yes" to the "on or off time" decision point to determine if the machine operator requested a change to the on or off time value. If a change is requested, the program delays "not" as the decision point "switch actuation later". If the baby monitor delay switch-122 800 is pressed by an operator, the program branches "yes" to the processing function "disable interrupts" because such a change will reduce the dwell time from 359 °. If the delay switch is not pressed, the program branches at the point "no" from "switch activation later" to the processing function "indicate invalid change". This processing function contains instructions to produce a visual indication in the control, so that no change, because the acceleration switch is depressed and such a change would cause the pause to be reversed. The program then returns to the main program. If a switch-off time change has been requested, the program branches from "on or off time" to "off to the decision point" faster start switch slam. If the acceleration switch is pressed, the program branches "yes" to the processing function "disable interrupts", because such a change would result in a pause time below 359 °. If the acceleration switch is not pressed, the program branches in the point "no" to the processing function "indicate illegal change" purpose an indication that no change is allowed because the acceleration switch is not depressed or the delay switch is depressed and such a change would cause the pause to be reversed. The program then returns to the main program. The processing function "block interrupts" contains the instructions to block all interrupts for the station computer, while the value is changed in steps of on or off time. The program then enters the processing function "new value in degrees =" old value in degrees ± 1 ° ", which contains instructions to generate a new value in degrees for a selected on or off time by increasing or decreasing the old value in degrees by a degree depending on whether the delay or acceleration switch is depressed. The program then comes to the decision point "section position = new value in degrees", Irtóry contains the value in degrees of the current section position in the cycle with the new value in degrees. If the values in degrees are equal, the change is not allowed because the computer A section may erroneously generate an enable or disable control signal, for example, if the value in degrees decreases after executing the interrupt program of FIG. 10 for the current section position but before executing the interrupt program for the next position. Hence, the program branches "yes" to the processing function "indicate invalid change" which contains instructions to produce a visual indication that the value in degrees cannot be changed at the given time. The program then enters the processing function "enable interrupts". If the position of the section is not equal to the new value in degrees, the program branches from "no" to "write new value in degrees", which contains instructions to replace the old value in degrees from the section stored in the computer with the new value in degrees. This new value is then read by the control computer the next time the program in Fig. 6 is executed. The program then enters the processing function "enable interrupts" which includes instructions to enable interrupts that were blocked from generating a new value in degrees. This is the end of the function timer change subroutine and the program returns to the main program. In summary, the invention relates to a control system for a glassware manufacturing apparatus. The apparatus has a molten glass body, a unit of individual sections for forming glass articles, and a unit for feeding molten glass bodies to individual sections. Each of the individual sections comprises a molding device for forming glass products in a cyclic series of defined molding steps corresponding to a plurality of control signals and control systems for producing control signals. The control system has a machine control computer connected to a set of individual section computers. , one for each of the individual 20 sections of the machine. The control computer of the device loads the sections individually with the control program and time data in order to form individual glass products. Each station computer then produces control signals according to the control program and time data. The time data includes the on and off time values for each of the glass forming machines, which time values define the pause time during which the mating machine 30 is activated to form the glass products. A section operator control is used to produce the desired shift selected. one of the time values. The control system comprises circuits for generating a signal representing the selected forming devices for which it is desired to change one of the on and off time values, a circuit for generating a signal representing a selected one of the on or off time values, and a circuit for generating a signal indicating whether it is a desired increase or decrease in a selected time value. The computer of the section reacts to the signals to produce a change in the selected time values, before such a change causes a break reversal and a shift in one of the on and off time values.
