Abstract

A card inverter or “flipper” is used in connection with card printers and laminators for inverting cards which are to be printed and/or laminated on two sides, so that after operations on one side have been completed, the card can be inverted and fed back to the processing stations for processing the second side of the card. This can be done with cards that are being programmed, for example, “Smart Cards” that will be moved to different stations for processing, and also can be used in connection with lamination stations where the card will be printed on two sides, and then a laminate film layer placed over both sides of the card The card inverter or flipper is supported about a central axis that bisects the plane of the card, and the inversion is about this axis so that the card plane is maintained in the first position of the card as well as the inverted position of the card.

Claims

1. A card handling mechanism for inverting a card about a central axis of the a plane of the card comprising a card support, a pair of mounting shafts, one on each side of said card support, said shafts having coincidental axes and lying along a central plane of a card support, first and second rollers rotatably mounted on the card support on opposite sides of the plane of the card support, the rollers clamping a card therebetween and driving a card when one roller is rotated about an axis, a first gear mounted on a first shaft of said pair of shafts, a second gear mounted on an end of one roller and engaging the first gear, a drive effective to drive the card support from a second of the pair of shafts to selectively rotate the card support about the axes of the shafts, the first and second gears being the same size so that the card support can rotate about the shaft axes without driving the one roller.

2. The card handling mechanism of claim 1, wherein said card support comprises a pair of card support plates, a card positioned between said card support plates, each of the rollers extending through openings in a separate plate to engage a card between the card support plates.

3. The card handling mechanism of claim 1 and a stepper motor, forming a part of the drive to rotate the card support, the stepper motor being controllable to stop rotation of the card support at a selected indexed position.

4. A card handling mechanism for turning an identification card about a central axis lying in a plane of the card, said card handling mechanism including a pair of spaced apart support walls, an assembly of a pair of card guides supported on first and second housings on opposite sides of the card guides, and each of the housings being supported by a separate mounting shaft extending through bearings on the respective spaced support walls, a single pair of drive rollers mounted in mid portions of said card guides, one on one side of a first card guide and the other on the other side of a second card guide, a drive gear on a first of said mounting shafts for driving one of said rollers, the rollers having shaft portions extending into and rotatably mounted on the housing supported by a second of said mounting shafts.

5. The card handling mechanism of claim 4 and a card sensor on one of said card guides for sensing the presence or absence of a card between the card guides.

6. The card handling mechanism of claim 4, wherein said card guides comprise plates having mounting flanges on opposite side edges thereof, the mounting flanges of each plate extending in direction away from the other plate, and said flanges being mounted to a gear housing and a drive housing, respectively, for supporting the two plates forming the card guide in a spaced apart position.

7. The card handling mechanism of claim 4 and separate controllable motors drivably connected to the respective mounting shafts, and a central control for controlling said motors.

8. The card handling mechanism of claim 4 and a controllable motor for driving a second mounting shaft, the housing supported by the second of the mounting shafts, being drivable connected to both of the card guides, said controllable motor being controlled to index the card guides at different angular positions about the axis of said second mounting shaft.

9. A card handling mechanism for inverting a card about a central axis of the plane of the card comprising a card support;

a pair of mounting shafts, one on each side of said card support;

said mounting shafts having coincidental axes and lying along a central plane of a card support;

a clamp to hold a card relative to said card support, wherein said clamp comprises a drive roller and a pinch roller, the pair of mounting shafts including one mounting shaft having a drive gear thereon;

a driven gear mounted on a shaft for the drive roller and engaging the drive gear, whereby driving one of said pair of mounting shafts causes the drive roller to be driven;

the second of said shafts being drivably mounted to a drive housing;

said rollers having roller shafts that are rotatably mounted in said drive housing;

the second of said mounting shafts being drivably connected to the drive housing;

said card support comprising a pair of card support plates spaced to permit a card to pass between the card support plates, each roller extending through an opening in one plate, respectively, to engage a card between the card support plates, the card support plates being substantially planar, and having flanges bent out of the planes of the respective plates along side edges thereof, the flanges of each plate extending in a direction away from the other plate, and the flanges on one side of both plates being attached to the gear housing, and the flanges on the other side of both plates being attached to the drive housing; and

a drive effective to drive the card support from at least one of the pair of mounting shafts to rotate the card support about the axes of the mounting shafts.

10. A card handling mechanism for turning an identification card about a central axis lying in a plane of the card, said card handling mechanism including first and second support members on opposite sides of a card path, each of the support members being supported by a separate mounting shaft, a single pair of drive rollers mounted on and extending between the support members, the drive rollers being positioned to engage and selectively hold and drive a card, a first selectively operated drive to one of the rollers to rotate the rollers about roller axes, and a second selectively operated drive to one of the support members, the second drive rotating the support members, the rollers and a card held between the rollers while the rollers remain holding the card between the rollers and do not rotate about the roller axes.
