Abstract

A travelling gate G of a sorter is driven by means of a toothed belt B which is also used to drive the gate insertion rolls R as shown in Figure 1. The belt is guided between offset pulleys P1, P2, P3 by which it rotates insertion rolls R. The gate G is advanced by the belt and restrained by cable 13, being indexed by pawl and ratchet 1, 2. For reverse indexing, clutch 15 drives ratchet 2 anti-clockwise to wind the wire onto the capstan 14.

INDEXER FOR TRAVELLING GATE SORTER (Cont'd)

A travelling gate G of a sorter is driven by means of a toothed belt B which is also used to drive the gate insertion rolls R as shown in Figure 1. The belt is guided between offset pulleys P1, P2, P3 by which it rotates insertion rolls R. The gate G is advanced by the belt and restrained by cable 13, being indexed by pawl and ratchet 1, 2. For reverse indexing, clutch 15 drives ratchet 2 anti- clockwise to wind the wire onto the capstan 14.

A modified mechanism for indexing the gate in both directions, as shown in Figure 2, comprises a first pawl and ratchet arrangement 1, 2 the pawl 1 of which is activated once for each indexing movement of the gate in the forward direction, and a second pawl and ratchet arrangement 3, 4 the pawl 3 of which is activated once for each indexing movement in the reverse direction. The first ratchet 2 also serves to drive the second ratchet 4 via a Geneva mechanism 5 against a spring (not shown) during forward movement of the gate. The second ratchet 4 is mounted on a shaft 6 which drives the gate past the bins (e.g. via wire 13 connected to the gate and wrapped around capstan 14 on the shaft 6 as shown in Figure 1).
