International Classification:

B65G 1500

US Classification:

186 68, 186 69, 198594, 198812

Abstract:

An extension/retraction mechanism for a take-away conveyor in a checkstand. The extension/retraction mechanism selectively stops and holds the telescoping take-away conveyor at the scan-and-bag position as the telescoping take-away conveyor is moving between walk-through and scan-and-pass positions. The extension/retraction mechanism includes a cam follower that is pivotally attached to the telescoping take-away conveyor for movement therewith. The cam follower rides within a cam track as the telescoping conveyor moves between the scan-and-bag, walk-through, and scan-and-pass positions. The cam track includes a series of turn surfaces so that the cam follower changes course as the telescoping take-away conveyor moves backward and forward. The cam track also includes at least one pocket for retaining the cam follower when the telescoping take-away conveyor is in the scan-and-bag position.

Abstract:

A modular conveyor that may used, for example, as a take-away conveyor or an accumulation conveyor in a checkstand. The modular conveyor includes front and rear brackets that are configured for attachment of rollers for the conveyor belt. The front and rear brackets are designed so that they may be attached to a deck, such as a wooden board. The belt is attached on the rollers, and wraps over the deck. The length of the deck, or wooden board, may be varied, permitting same-shaped brackets to be used to form variable lengths of conveyors. Two brackets may be used for each end of the conveyor, one each for supporting opposite sides of the roller at that end of the conveyor. In this manner, the deck may be widened or narrowed, so that the same brackets may be used to create conveyors of various widths.
