Abstract

This is a low cost transport device for a document stacker. The documents are fed to the system input A at random, with the main transport belt 1 being externally driven. The documents are thus conveyed along the main belt path and pass by a number of stacker entrances. Depending on whether the selector gate 2 is open or closed, the transported document would be selected for transfer either to a stacker pocket 3 or not. If the former, the paper document is conveyed along a guide 4 toward the corresponding pocket 3, using a stacker belt 5 wrapped about two pulleys 6 and 7. The paper document is in fact moved by using the friction between the main belt and paper and then the paper and stacker belt.

Transport Device for Document Stacker

This is a low cost transport device for a document stacker. The documents are fed to the system input A at random, with the main transport belt 1 being externally driven. The documents are thus conveyed along the main belt path and pass by a number of stacker entrances. Depending on whether the selector gate 2 is open or closed, the transported document would be selected for transfer either to a stacker pocket 3 or not. If the former, the paper document is conveyed along a guide 4 toward the corresponding pocket 3, using a stacker belt 5 wrapped about two pulleys 6 and 7. The paper document is in fact moved by using the friction between the main belt and paper and then the paper and stacker belt.

No external power source is provided for the stacker belt; instead, the stacker belt is driven through main stacker belt motion.

For that purpose, the stacker belt 5 is only partially imbedded in the pulley 6 (Fig. 2), thus providing a direct contact between the main driving belt and the stacker driven belt. An idler roller 8 is also provided to ensure proper contact between the driving and driven belts. Belt wearing is considerably limited by having the Idler roller 8 slightly offset from the contact points between the driving and driven belts.
