  • the outer layer 413 has its upper edge 415 contoured in the manner of analog control of the process programmed.
  • Both the inner layer 417, and the outer layer 413 have apertures coinciding whenever a digital operation is to be carried out i.e. an on-off type operation, as is best shown by the compositely formed aperture 421 in FIG. 14.
  • the apertures, such as 421 occur at heights conforming to the holes, such as 423, in the brass bar 425 of the programmer itself (FIG. 12).
  • the programmer also incorporates an analog setpoint transmitter that can be programmed to vary a 3-15 PSI set-point signal to effect pneumatic process controlling.
  • This set-point transmitter includes tracer nozzle 427 (FIG. 14), carried by analog tracer head 429, in turn sensing the upper edge 415 of the outer layer 413 of chart 411.
  • the analog tracer head 429 is contained at the rear of brass bar 425, (not seen in FIG. 12) and is therefor opposite the digital on-off aperture seeking arrangement (of holes 423) visable from the face of bar 425 of FIG. 12.
  • FIG. 14 is a schematic, merely to explain the operation of the analogpick-up and the digital operation in one view, each operation really being 180 around the chart or on opposite sides of brass bar 425.
  • the chart of FIG. 13 is capable of use through the structure of FIGS. 12, 14, solenoids and cylinders and valves of FIGS. 8 and 9, of controlling all of the necessary variables that directly govern the patterning effect of the yarn.
  • the control system operates other electrical or pneumatic devices that energize and de-energize the dye chemical pumps, the dye diverter valves, such as 201 and 203 (FIG. 2), the infra red ovens, the main drive chain and any other dyeing apparatus desired.
  • These digital functions on and off controls
  • Velocity of the spray head cylinders such as cylinder 131 (FIGS. 2 and 8) provide maximum versatility best under variable control, that is control that is maintained in the analog fashion by this programmer through the analog set-point transmitter of FIG. 12.
  • the set-point signal varies from a 3 PSI signal to a PSI signal via a pneumatic nozzle, i.e., 427 in FIG.
  • a 15 PSI signal output is generated, and when the nozzle is at the bottom of the chart, as depicted at point 431, a 3 PSI signal output is generated.
  • the plastic composite chart4l1 is driven at a predetermined rate perpendicular to the motion of the profile tracer, and therefor, the output is a function of time, as well as, the profile tracer position in a vertical plane.
  • FIG. 8 is an electrical-pneumatic showing to illustrate both the analog and digital control outputs that govern the speed and position of the spray nozzle cylinders.
  • the pneumatic transmitter signalling from the programmer is connected to each pneumatic relay for each spray head station.
  • These analog signals from the electro-pneumatic programmer travel over the 3l5 PSI signalling pressure line 501 directly to pneumatic relay No. 1, shown at 215 in FIG. 8, and also by branch lead 503, in communication with lead 505, to pneumatic relay No. 2, shown at 507, and also via lead 503 to pneumatic relay No. 3, shown at 509.
  • Each spray nozzle solenoid valve is electrically energized by separate function switches (see FIG. 11) when a selected punched hole is sensed at the plastic chart, as described.
  • the normally closed port, as seen at 521 for solenoid valve No. 1 in FIG. 8, of the solenoid 217 is connected to the retract port on the cylinder 131 over pressure lead 523, and the normally open port 525 of the solenoid 217 is connected to the extend port on the same cylinder over line 526, to control piston rod 133 (FIGS. 2 and 8).
  • spray nozzles at stations 2 and 3 are controlled.
  • Each spray nozzle station is equipted with two or more individual nozzles for spraying dyes and chemicals (see nozzles 151 and 153 of FIG. 5). At any given moment, however only two of the nozzles are attached to the same dye chemical pump (see FIG. 9).
  • FIG. 9 shows a threeway diverter valve assembly that passes the dyes or chemicals from a pump to one or the other aforementioned spray nozzles per station, depending upon the electrical state of the diverter solenoid valves, such as 201 and 203 in FIG. 2.
  • Each diverter valve as shown in FIG. 9, is assigned to a separate function switch in the programmer and, as the desired pattern dictates, holes can be punched in the plastic chart, and the diverter valve energized resulting in a threeway valve control directing the dye or chemicals to the diverting path, and consequently to one or the other of the spray nozzles.
  • high pressure air is applied over lead 561 to the diverter solenoid 563 which operates over lead 561 to drive the valve cylinder 567 to the left and over lead 569 to drive the valve cylinder 567 to the right.
  • Valve cylinder 567 is connected to linkage 569 which is adapted to operate the pneumatic threeway valve 571.
  • FIG. 11 there is shown the electrical schematic for wiring the standard programmer to achieve the functions necessary to the present invention.
  • the programmer comes equipped with the function switches No. 1 through No. 15 and it has already been shown how function switch No. 2 has been used as switch 461 in FIG. 8. All of these 15 switches (the programmer may come equipped with 25 switches but it was only necessary to use the 15 designated switches herein) are shown in their upper position, which is the position only attained by a hole in the chart activating the corresponding microswitch to cause it to move to the upper position.
  • all function switches 1 through 15 are normally in the lower position and only moved to their upper position when, or at that particular time that, a hole in the composite plastic chart 411 uncovers the particular nozzle associated with that function switch.
  • the circuitory is supplied with 110 volts AC between input terminals 601 and 602, respectively fused for amps at 603 and 605.
  • the neutral side of the line is designated as 607, 608 from terminal 602, and the other side of the line at 609 from terminal 601.
  • the ON button is shown at 611 for applying power to the starting circuitory, generally appearing in the upper portion of FIG. 11.
  • Switch 611 is one of those button switches 402 appearing in FIG. 7. Closure of the power switch 611 provides voltage to the input side 613 of the 24 volt transformer 615 to convert the 110 AC to 24 volts AC on the secondary side 617. This low voltage supplies the lamps indicated as 619 to indicate that power is ON, 621 showing the cycle has begun (usually the cycle requires approximately 8 /2 minutes to conclude) 623 for reset, 625 for running and 627 for hold.
  • depression of the CYCLE ON button 631 applies power to the relays CR-l, shown at 633, and CR-2, shown at 635.
  • Energization of relay 633 causes its contacts CR-l to close, thereby powering the upper portion of the circuit of FIG. 11, but its closed contacts CR-l to open (these are normally closed as shown by the slanted line thereacross), thereby relieving the reset momentary circuitory, including reset switch 641, Function Switch No. 1 etc.
  • the other relays operate their contacts in the same manner as above described and contribute only mechanical skill to the invention.
  • the Function Switches No. 2 through do enable the various functions of the present invention to be carried out and these will now be described in detail.
  • Function Switch 3 is provided as an addition to Function Switch 2, in that further control may be had over the circuitory, depending upon whether toggle switch 1 is closed or not, because this toggle switch may be operated manually to enable the aperture assigned to Function Switch 3 to pull it in at a different time than Function Switch 2 and maintain the energization of relay CR-4 in spite of the fact that the binary hole assigned to Function Switch 2 has now passed in time, due to movement of the chart.
  • Function Switches 4 and 5 operate in the same manner to control the solenoid valve No. 2, shown at 511 and Function Switches 6 and 7 perform the same functions relative to solenoid valve No. 3 identified heretofore at 513.
  • Function Switch No. 8 initiates pump motor No. 1, shown at 691 to insure that the pressure is available for spraying the fluid from spray station No. 1.
  • Function Switch 9 and Function Switch 10 energize motors 693 and 695 for their respective same purposes.
  • Function Switch 11 provides a holding circuit for FS-S, FS-9, and FS-10, respectively.
  • Function Switch No. 12 energizes diverter valve No. 1, shown at 201 in FIG. 3 and explained in detail at 571 in FIG. 9.
  • Function Switches No. 12 and 13 control diverter valves No. 2 and No. 3.
  • Function Switch 14 energizes relay CR-12 to operate solenoid valve No. 3 shown at 513 (FIGS. 8 and 11). Function Switch 14 operates CR-O relat to energize the DC control starter 701 (FIG. 11) for the main DC motor, the Time Delay-ON, shown at 703 in FIG. 11 for the oven and the Time Delay-OFF shown at 705 for the Drive Delay.
  • FS-15 returns all diverter valves to normal i.e., de-energizes them in the manner of FS-11 for all pumps.
  • the Function Switch FS-l is provided to reset the cycle at any time.
  • the MR symbol 701 reverses the motor of the programmer with switch 702 in one position, and the MD symbol is for main drive of the programmer motor with switch 702 in its other position.
  • the conventional nozzle applies an acid dye in an aqueous solution to yield a suitable viscosity when using 1,300 two ply nylon filament yarn approximately at F temperature for the dye.
