  • a pulse is provided vto the index motor B-3 through contacts K10-2 and K12-2 causing the motor to move the control sprocket sufficiently to close limit switch LS-12 causing relay K-21 to energize providing a power path through limit switch LS-12, LS-11, and closed relay contacts K-21(1) directly to the index motor B-3 which rotates the cam support shaft 153 until the actuator of limit switch LS-12 falls into the next detent of the control sprocket and is opened disconnecting power from the index motor. Therefore whenever the trail edge of the sheet material goes through the light beam projecting to the photocell CR-l normally open contacts K12(2) and K-10(2) are closed supplying power to the index motor.
  • the first sheet When the sheet material enters the modular unit 100, the first sheet will be passed into the first copy catch bin due to the diverting mechanism 130 and the rst diverting mechanism 130 being in interference with the path of paper movement at the initial or reset position.
  • the interrupting and remaking of the light beam DS-2 into the photosensor CRl of the sheet distributor module will cause the index motor B-3 of the module to step under the same control as previously described with reference to the sheet distributor 200. This procedure continues with regard to additional modules until such time as the programmer M-2 reaches coincidence and the sheet distributor and modular units are reset by the memory wheel 300.
  • jam detection controller timer M-6 is provided to close normally open contact M-6 thereby energizing jam control relay K-19.
  • jam control relay K-19 normally closed contacts K-19(3B) open which removed power from all drives, and contacts K-19(3A) close to energize DS-3 indicator lamp to indicate that a jam has occurred in the sheet distributor.
  • Normally closed contacts K19(1A) open to isolate the power lines of the reproducing machine from the sheet distributor, and relay contacts K19(1B) close shorting the power lines 47 and 174 together which indicate to the reproducing machine that a jam has occurred and to begin machine shut down.
  • the jam detection controller timer M-5 will be energized to energize line 29 for actuating jam control relays K-8 and K-9, and contact M-S of the appropriate sheet distributor module which actuates jam indicator light DS-3 to in dicate a paper jam has occurred.
  • the energization of jam control relays K-8 and K-9 causes their appropriate contacts to be actuated thereby accomplishing the sheet distributor shut down provided that sheet material is not holding limit switch LS7 in a closed position, as previously stated, in which case the sheet distributor will function as hereintofore described.
  • jam control relay contact K9(1) is put in series with the power line to jam detection controller timer M-6 to be opened by the actuation of jam control relay K-9 for preventing the controller M-6 from indicating a paper jam has occurred in the transition portion of the sheet distributor when in actuality it has occurred in a sheet distributor module.
  • jam control relay K-8 The contacts of jam control relay K-8 are actuated whereby normally closed contact K-8(3) opens to remove power from line 14 which is the power line for all the index mechanisms and control components. Contacts K-8(1A) close shorting power line 19 and 135 to indicate to the reproducing mechanism that a jam has occurred and to retain the count of the number of copies reproduced. When the paper jam is cleared the reproducing machine may again continue to reproduce copies of an original document until the reproducing machine programmer has reached coincidence indicating that the desired copies have been reproduced.
  • Relay contact K-8(1B) opens to isolate this circuit from the sheet distributor in the same manner as relay contact K-19(1A) previously described, and relay contact K-8(2A) closes to short power lines 47 and 108 together which causes the reproducing machine to complete the reproducing cycle and to shut down while retaining its count of the number of copies reproduced. With a jam occurring, M5 contacts will remain closed energizing the jam indicator lamp DS-3 which will remain energized until an interlock is broken thereby preventing further operation of either the reproducing machine or the sheet distributor.
  • lines 108 and 19 are energized which through line 15 actuate the memory wheel solenoid L-2 and energize memory wheel control relay K-14 through diode CR-4, resistor R-4 and capacitor C-4 to provide a finite time delay before energization of relay K-14. Therefore, after the time delay has occurred relay K-14 will energize opening the normally closed contacts K-14 and disconnecting the power source from the memory wheel solenoid L-2. This momentary de-energization of the solenoid effects the punching out of pins 302 on the memory wheel to actuate the limit switches positioned adjacent the rotating pins of the memory wheel.
  • the memory wheel 300 is used for both resetting and terminating operation of the sheet distributor mechanism. In some situations it is desirable to terminate operation of the sheet distributor such as in the case of a malfunction in the reproducing machine, but not to reset the mechanism for a new run. However, when the number of copies being reproduced of the original document has been reached, it is desired to terminate operation of the sheet distributor and to reset it for the beginning of another program. Therefore, control relay K-3 is provided to be energized when it is desired merely to terminate operation of the sheet distributor without resetting the distributor for a new program. To this end, the normally closed relay contacts K-3(2) are opened to interrupt all the reset circuits by interrupting the power to line 22 from which all the reset circuits are supplied.
  • normally closed contact K-3(3) is opened to interrupt the reset of the programmer M-2. Since all of the reset limit switches are supplied with power through line 22 the interruption of the power to line 22 prevents the closing of LS-l, LS-2, LS-3, LS-4 and LS-S from effecting a reset of the distributor. However, it does not interrupt the power to limit switch LS-6 which controls the termination of the sheet distributor operation and therefore when the pins 302 of the memory wheel 300 contact normally closed limit switch LS-6, the switch opens and causes the sheet distributor to terminate operation. Therefore, upon restarting the reproducing mechanism and the sheet distributor, the distributor is not reset but again continues the previous program.
  • line 108 is energized actuating the memory wheel solenoid L-Z and moving the pins 302 into actuating position whereby they will actuate the limit switches LS-l through LS-6 to reset the sheet distributor and terminate operation. Therefore, the only way in which the sheet distributor may be reset is upon a coincidence signal through line 108 indicating that the reproducing mechanism with which it is utilized has reached coincidence, that is the number of reproductions of an original document has been reached.
  • Actuation of limit switch LS-l energizes reset control relay K-S to reset the distributor.
  • limit switch LS-Z is actuated to close the reset path for the programmer M-2 resetting the programmer for the next program.
  • limit switch LS-3 is actuated to reset the catch tray portion of the sheet distributor 200 applying power directly to the index motor B-3 from line 14 which causes the diverting mechanisms to be rese-t.
  • This resetting to position No. l is accomplished by power being supplied through limit switch LS-11 which energizes relay K-21 closing the normally open contact K-21( 1) directly applying power to the index motor B-3 until limit switch LS-11 is de-actuated by means of its actuator moving into the detent on the sprocket 156.
  • Limit switch LS4 energizes the reset relay K-6 for all sheet distributor modules to reset each module by applying power 4through LS-11 in each module to drive each index motor B-3 until LS-11 is de-actuated.
  • Limit switch LS-S is energized closing contact LS-SA to energize sheet distributor delay shut down control relay K-13, and LS-SB contacts open to de-energize reset control relay K-S which was previously energized through limit switch LS-l, thereby insuring that enough time elapses prior to sheet distributor shut down to allow the last sheet emerging from the reproducing machine to arrive at its predetermined destination.
  • the last limit switch on the memory wheel to be actuated is LS-6 which is actuated after operation of the reproducing machine is terminated. At this time the only power path left to the sheet distributor is through limit switch LS-6 and K-2( 1) contact. Therefore, when limit switch LS-6 is actuated it de-energizes relay K-2 and terminates all power to the sheet distributor except power to relay K-18 and the programmer M-2 thereby leaving the sheet distributor in a stand-by condition for another program.
  • a sheet distributor for use in operative relationship with an apparatus for forwarding sheet material thereto including a plurality of catch trays supported in space relation to each other,
  • a catch bin positioned adjacent said path of movement for the collection of non-distributed sheet material
  • a second diverting mechanism positioned adjacent said path of movement and said catch bin actuable into and from interference relationship with said path of movement to divert sheet materia] into said catch bin

  • programming means Iselectively actuable to determine a preselected number of sheet material to be fed past said second diverting mechanism toward said catch trays, said programming means being operably coupled to switch means to count the number of sheets fed into the distributor and to actuate said lsecond diverting mechanism into interference with said sheet material in response to lthe passage of the preselected number of sheets beyond said second diverting mechanism.
