Title: Obtaining alignment between two rotatable drums of a graphic reproducing apparatus
IPC: H02P5/56
Filed: 1974-12-12
Abstract: 1478917 Synchronizing graphic reproduction apparatus RUDOLF HELL GmbH 12 Dec 1974 [13 Dec 1973] 53839/74 Heading H2L An apparatus and method for aligning and running in synchronism two synchronous motor driven drums where each motor is supplied from an individual or a common supply through a frequency changer wherein the amount of misalignment is detected by sensing marks on the drums and a bi-directional counter operated accordingly to add or subtract pulses from a clock pulse signal used as a controlling reference supply to one frequency changer. As shown a scanning cylinder 1 is driven by synchronous motor 2 which is supplied from mains 7 through frequency changer 5 at a frequency f 2  dependent on the frequency of clock signal 9. A printing cylinder 3 is similarly driven by synchronous motor 4 supplied from frequency changer 6. The clock signals are derived from a single oscillator 12 in the system shown but separate oscillators could be used. Each drum is provided with respective marks 17, 21 which co-operate with pulse generators 16, 20 to provide pulses to set and reset coincidence circuit 19. The circuit 19 is conditioned to accept a single pulse from the scanning drum generator 16 which causes an up-down counter to have its up terminal connected to line 24 until a pulse is received from the printing drum generator when the down terminal is connected to line 27 through a reducer circuit which is set to produce an output pulse after a given number of input pulses until the counter reaches zero when the two drums should be aligned. The output pulses from the pulse reducer circuit can be used to either suppress (Fig. 2) or add (Fig. 3) pulses to the clock pulse train on terminal 28 depending on whether motor 2 is to be slowed down or speeded up to attain synchronism. In the case where pulses are added to the frequency of clock pulses from terminal 24 to the pulse reducer and counter is halved. A coincidence checking circuit continuously monitors the pulse generator outputs and indicates when the drums are aligned.

Rectangular record members, e.g. cards, are separated from a stack by pivoting the top card in its plane about an abutment acting on one edge of the card and then feeding the card in a direction aligned with the edge of the card after pivoting. Fig. 1 illustrates apparatus in which cards 1 are stacked in a hopper, one corner 2a of which is shaped to permit pivotal movement of a card in its plane from the fullline position to the dotted-line position of Fig. 1; a throat 3 at the bottom of the hopper allows the lowest card to pass therethrough. A retractable picker knife 4 is carried on an arm 5 pivoted at its end 6 near the corner 2a, and the arm is reciprocated by means of flywheel 7 and connecting link 8. Friction roller 9 or a pair of co-operating rollers complete the separation along the line of a guide 10. In an alternative embodiment (Fig. 2, not shown), at least one picker knife is carried on a continuously rotating disc, a knife being raised for part of a rotation to swivel the bottom card and being retracted after alignment of the card with the feed guide. The end card may also be swivelled in the stack by means of a conveyer belt (Fig. 4, not shown) which is frictionally engaged with the card for the required period of time by rollers controlled by an electromagnet, the rollers, being pushed through an aperture in a plate contacting the face of the stack.
