Abstract

A conveyer with an automated sorting system comprises a transport mechanism, a guide mechanism, and a sorting mechanism. A sorting sensor activates electrical spiral tubes which, in turn, actuate left and the right separation pieces to guide pins of the transport mechanism along desired guide rails so as to alter their original moving paths. More particularly, the guide pins are capable of moving along three different directions: left, middle, and right. The article intended to be transported is thus sorted out automatically and is sent to the designated area.

Claims

1. A conveyor with an automated sorting system comprising:

a transport mechanism including a motor, a pair of longitudinally extending and laterally spaced chains drivingly connected to said motor, a plurality of sliding tubes extending laterally between said pair of chains at longitudinally spaced locations, a plurality of blocks slidably mounted on said sliding tubes, a plurality of plastic sleeves disposed on both ends of each of said sliding tubes, first and second sets of protruded pins each of which is attached at one end to a respective one of said pair of chains and at another end thereof to a respective one of said plurality of plastic sleeves for interconnecting said sliding tubes to said pair of chains, a plurality of compression springs disposed about each of said first set of protruded pins between one of said pair of chains and an end of each of said sliding tubes, and two laterally spaced guide pins projecting from a lower portion of each of said plurality of blocks;

a guide mechanism including first and second sets of laterally spaced guide rails positioned beneath said plurality of sliding tubes and a set of laterally spaced correction guide rails positioned at terminal ends of said first set of guide rails, each of said first and second sets of guide rails and said set of correction guide rails being adapted to be engaged by said guide pins for guiding said plurality of blocks;

a sorting mechanism including a plurality of individually controllable separation pieces for selectively engaging said guide pins and shifting said plurality of blocks along said sliding tubes to cause one of said guide pins to engage a respective one of said first and second sets of guide rails and said set of correcting guide rails so as to reposition said blocks along said sliding tubes; and

a sensor for controlling the operation of said separation pieces.

2. A conveyor according to claim 1, wherein said first set of protruded pins comprise long protruded pins and said second set of protruded pins comprise short protruded pins, each of said sliding tubes being connected to said pair of chains through one of said long protruded pins and one of said short protruded pins.

3. A conveyor according to claim 1, wherein said first set of guide rails include first ends which are laterally spaced and said first set of guide rails diverge, laterally outwardly from the first ends thereof.

4. A conveyor according to claim 1, wherein said separation pieces include slanted surfaces that are adapted to engage said guide pins, said surfaces slanting in a direction substantially perpendicular to a longitudinal direction of movement of said plurality of blocks.
