  • the pin 262 is out of engagement with a slot in the wheel 266, the rim 264 is effective to prevent rotation of the wheel 266.
  • the incrementer roll 252 is driven intermittently by means of the wheel 266 with which the roll 252 is connected, and incremental movement of the card 20 through the punch station 26 is attained by energizing the actuator 52A.
  • the actuator 52A is similar to the actuator 52 and is rendered operative by the application of a voltage to its terminals 105.
  • the coil 286 is de-energized so as to release the gate 282 at the same time as the actuator 52A is energized.
  • the actuator 52A is effective on the lever 274 to swing the lever about its flexure 276 against the action of the spring 278, and the lever 274 with this movement moves the pressure roll 272 into forceful nipped relationship with respect to the incrementer roll 252 which is incrementally driven from the wheel 266.
  • the card 20 is thus incremented through the punch station 26.
  • the bail 214 moves upwardly.
  • the interposers 202 are held out of operating relationship with the upper edge 222 of the bail 214 by the magnets 204 and 206; and, if the controlling circuitry so directs, the pistons 212 effective on certain ones of the interposers 202 have air pressure from the pump 414 directed to them and are then operative to move these interposers into alignment with the bail edge 222 so that the edge 222 makes contact with the corresponding edges 224 of the interposers and moves these interposers upwardly along with the punches 198 to which these interposers are connected.
  • the punches 198 are then effective to pass through the document card 20 positioned between the stripper 192 and die 194 so as to punch corresponding holes 22 through the card 20.
  • These holes 22 will be in three aligned columns in the punch area of the card 20, for example, columns 1, 33 and 65.
  • These pistons 212 have air under pressure supplied to them through the corresponding air passages 236, and these passages are opened by energization from the controlling circuitry of the corresponding solenoids 232 effective on the associated valves 234.
  • the bail 214 after punching has occurred, is effective through its part 226 to return the previously active punches 198 into their inactive positions; and, after this movement of the punches 198 has occurred, the rolls 252 and 272 are active to move the card 20 into another incremented position in which a like punching action may occur.
  • This punching action in the station 26 continues until all of columns 1-32 and the columns in tiers 2 and 3 aligned therewith have had the appropriate holes 22 punched in them.
  • the card As the card 20 is being punched in the station 26, the card enters the nip of the rolls 306 and 300.
  • the roll 300, as well as the roll 298, are driven from the pulley 304 and belt 406; and the roll 300 acts to urge card 20 forwardly due to the action of the pressure roll 306 held by the spring 308 with a relatively low pressure on the card 20.
  • the actuator 52B After punching of the card has been completed, the actuator 52B is energized to become effective, and this actuator moves the pressure roll 310 into forceful engagement with the roll 298 through the lever 312.
  • the card 20 is thus propelled forwardly at this time with a continuous movement by the rolls 300 and 298; and this movement is positive since the pressure roll 310 bears with much greater force on the roll 298 than the force with which roll 306 bears on roll 300.
  • the card detector 316 which is in approximate alignment with the rolls 298 and 300, at this time signals the controlling circuitry for the machine that the card 20 is at the position of the detector 316.
  • the actuator 52B is operative for only a relatively short time, sufficient to start the card 20 moving at high speed after punching has been completed; and during this time, the stepper motor 342 is inactive and the pressure rolls 344 and 346 are stationary. The rolls 300 and 306 complete the movement of the card 20 into engagement in the nips of the rolls 334 and 344 and the rolls 336 and 346 and hold the card 20 from rebound out of these nips. At this time, the stepper motor 342 is energized so as to move the card 20 to align its print positions 1, 33 and 65 respectively with the print wheels 318, 320 and 322.
  • the stepper motor is then stopped so that the card is momentarily stationary; and the corresponding hammers 354, 356 and-358 are actuated by the corresponding magnets 362 so as to cause print positions 1, 33 and 65 to be printed,
  • the print wheels 318, 320 and 322 are continuously revolving at high speeds, and the controlling circuitry is effective so that the hammers 354, 356 and 358 are moved downwardly into printing relation with the 'wheels 318, 320 and 322 and the card 20 at just the proper times so that the proper alphanumeric characters are printed to correspond with the punchings 22 that are in the corresponding punch columns 1, 33 and 65.
  • stepper motor 342 is again energized so as to incrementally rotate the wheels 334 and 336 to move the card 20 to align the next print areas 2, 34 and 66 with the print wheels 318, 320 and 322. Printing of these areas is completed in the same manner as print areas 1, 33 and 65; and, likewise, the printing of the other print areas on the card 20 is accomplished.
  • the stepper motor 342 is so energized as to continuously move the card 20 out of the print station 28 and into the nip of the rolls 388 and 384.
  • the roll 384 is continuously driven from the pulley 394, and the roll 388 is held in forceful nipped relationship with the roll 384 so that the card 20 is thereby moved into the stacker 30.
  • All of the cards 20 in the hopper 24 are punched and printed in the same manner and are stacked in the stacker 30.
  • the stack of cards in stacker 30 eventually reaches the resilient strip 400, they cause the strip 400 to actuate the stacker full switch 398; and the switch 398 is so connected with the controlling circuitry of the machine to cause the machine to cease operation at this time.
  • the various actuators in the machine may be easily removed from the machine for replacement.
  • the actuator 52 is simply drawn out of its fixture 54 which, due to its own resilience, yieldably holds the actuator 52 in position.
  • the actuators 52A and 52B are suitably held by any releaseable means with respect to the plates 280 and 314, and these actuators may thus be detached from these plates and from the machine.
  • the electricalpneumatic sub-assemblies 228 and 230 may be detached from the remainder of the machine by pushing down on the respective levers 250 so as to swing the associated springs 246 and release them from the fixed pins248 with which they have been engaged;
  • the subassembly 228 or 230 may then be pulled outwardly with respect to the block 200 so as to pull the associated terminal card 238 out of the associated socket 242.
  • the socket 242 normally exerts a compressive force on the card 238 and the strips 240 carried thereby, so this requires some force in making the disengagement.
  • the plunger 374 may be pulled out against its spring action from the corresponding opening in the bracket 360; and the bracket 360 may then be swung upwardly about its shafts 364 and 366. During this swinging action, the strip 376 carrying the contacts 378 disengage with respect to the socket 380 in substantially the same manner as the terminal card 238 has been separated from its socket 242 as previously described.
  • the spring pressed pin 372 may be thrust inwardly against its spring so as to release it with respect to the groove 370, and the bracket 360 may then be slid outwardly along and out of engagement with the shafts 364 and 366.
  • the document card punching and printing machine herein disclosed advantageously utilizes air pressure for raising the pick rolls 42, actuating the pressure rolls 272 and 310 and for actuating the interposers 202 for causing punching action.
  • the actual power, therefore, for completing these functions comes from the pump 414, and a relatively small amount of electrical power is required for controlling these functions.
  • the electrical stepper motor 342 is advantageously used in connection with the print unit 28 and particularly with the print wheels 318, 320 and 322 for incrementing the document cards 20 through the print station 28. It is desired that continuous movements of a document card 20 occur at times through the print station 28; and the stepper motor is capable of producing this movement.
  • the stepper motor 342 is also capable of producing a card incrementing action, stepping a card 20 from one print area to the next, with the actual duration of time at which the card stays in the incremented positions varying depending on which of the print characters on the wheels 318, 320 and 322 are to be printed. A maximum printing speed and throughput of cards 20 through the print station 28 is thus attained.
  • This variation of time does not exist with respect to punching; and, therefore, the mechanical incrementing device including the slotted wheel 266 is advantageously used with respect to the punch station 26, since this is a relatively inexpensive unit.
  • all of the various pneumatic actuators including the actuators 52, 52A and 52B as well as the piston solenoid assemblies 228 and 230, may be easily detached from the machine for easy replacement.
  • bracket 360 which swings upwardy about the support shafts 364 and 366 so that if there are any card jams in the print station, the jammed cards may be easily removed.
