Abstract

The machine includes stackers 1, 2, 3, 4 and 5 for receiving document cards from hoppers 6 and 7, respectively, on the left and right sides of the machine. Stackers 1, 2, 3 and 4 are accessible from the left side hopper 6 and stackers 5, 4 and 3 are accessible from the right side hopper 7. Stacking into hoppers 1 and 2 from the left side and stacking into hopper 5 from the right side is done conventionally. With respect to the common stackers 3 and 4, the functions performed by the machine are: 1) Normal stacking from the left side into stacker 3 or 4. 2) Normal stacking from the right side into stacker 3 or 4. 3) Progressive stacking from the left side into the stackers 3 and L. 4) Progressive stacking from the right side into stackers 3 and 4.

Opposed Feed Transports Having Shared Stackers

The machine includes stackers 1, 2, 3, 4 and 5 for receiving document cards from hoppers 6 and 7, respectively, on the left and right sides of the machine. Stackers 1, 2, 3 and 4 are accessible from the left side hopper 6 and stackers 5, 4 and 3 are accessible from the right side hopper 7. Stacking into hoppers 1 and 2 from the left side and stacking into hopper 5 from the right side is done conventionally. With respect to the common stackers 3 and 4, the functions performed by the machine are: 1) Normal stacking from the left side into stacker 3 or 4. 2) Normal stacking from the right side into stacker 3 or 4. 3) Progressive stacking from the left side into the stackers 3 and L. 4) Progressive stacking from the right side into stackers 3 and 4. 5) Normal stacking from either or both left side and right side hoppers into stacker 3 or 4. 6) Progressive stacking from either or both the left side and right side into stacker 3 or 4.

The transport above the common stackers 3 and 4 includes an upper card guide 10 and lower card guides 12 and 14. These guides provide a left-hand card groove 16 and a right-hand card groove 18. Idler rolls 20 and 22 are, respectively, disposed in the grooves 16 and 18, and movable card driving rolls 24 and 26 are disposed in the grooves 16 and 18 and cooperate with the rolls 20 and 22. The rolls 24 and 26 are constantly driven and are movable toward and away from the idler rolls 20 and 22 by electromagnets.

A left-hand transport belt 28 is disposed above the stackers 1, 2 and 3, being movably disposed on support rolls 30, 32 and 34. A right-hand transport belt 36 is disposed above stackers 4 and 5 and is movable over rolls 38 and 40. Each of the stackers has a spring mounted support bed 42 for supporting a stack of document cards, and a roll 44 is positioned above the support bed to facilitate the movement of cards into the respective stacker. Swingable pocket selectors 46, 48, 50, 52 and 54, actuated by suitable electromagnets, are disposed at the top of the stackers 1, 2, 3, 4 and 5, respectively. Document card sensors 56, 58 and 60 are, respectively, disposed between stackers 3 and 4, over stacker 5 and over stacker 2.

Control of entry by document cards into stacker 3 or 4 is done by controlling the start of card feeding from hoppers 6 and 7. The transport belts 28 and 36 run continuously.

The most likely use of function 5 above (normal stacking from either or both left side or right side) is string sorting. In this case, approximately half of the cards sorted are loaded into each of the hoppers 6 and 7; the string is started into stacker 3; when the next string starts, it is directed to stacker 4; the next string goes to stacker 3, etc., until both hoppers 6 and 7 are empty. Hoppers 6 and 7 are then reloaded, the left side from stacker 3 and the right side from

stacker 4. The process is repeated as many times as necessary to complete the sort...
