Abstract

Described is a method to permit picking up multiple parts spaced at one set of center lines and to insert the parts into styrofoam packaging of another set of center lines. Utilizing an IBM 7535 robot, capsule 1 is removed from the plastic puck 2, as illustrated in Fig. 1, and inserted into the nest 3 of a styrofoam pack tray. The plastic puck 2 is conveyed from a previous automatic filling and capping machine. The center distances of the capsules 1 are greater when placed in the puck 2 and narrower when placed in the nest 3. Styrofoam nest 3 consists of 10 rows of holes in one direction and 5 rows of holes in the other direction. This design permits insertion of 5 capsules at one time.

Variable-Pitch Gripper/Vacuum

Described is a method to permit picking up multiple parts spaced at one set of center lines and to insert the parts into styrofoam packaging of another set of center lines. Utilizing an IBM 7535 robot, capsule 1 is removed from the plastic puck 2, as illustrated in Fig. 1, and inserted into the nest 3 of a styrofoam pack tray. The plastic puck 2 is conveyed from a previous automatic filling and capping machine. The center distances of the capsules 1 are greater when placed in the puck 2 and narrower when placed in the nest 3. Styrofoam nest 3 consists of 10 rows of holes in one direction and 5 rows of holes in the other direction. This design permits insertion of 5 capsules at one time. To achieve this, the upper portion of the gripper 4 is used to provide the actuator motion to grasp five capsules at once from the five pucks 2 at the given centers, then move the capsules inward to align with the holes in nest 3. On the downward stroke, the gripper piston shaft 5, in Fig. 2, presses the link 6, causing it to move the slide plate 7 in a horizontal plane. Five vacuum heads 8 are affixed to the slide plate 7. With the center head remaining stationary, the two heads on opposite sides of the center head remain stationary only during the first 1/16" travel of the slide plate. By means of slot 9, the two outer heads move in and out 1/16". As slide plate 7 continues its side motion, the slot 9 engages the guide pin 10, causing the inner head...
