Abstract
Abstract A modular conveyor comprising a plurality of interconnected modules each module having a receptacle integral therewith and in which each module is pivotable about both a horizontal and a vertical axis. The module receptacles are in a closed position during conveyor movement along a straight path or through horizontal turns, while during movement of the conveyor through a vertical turn, the receptacles are in an open position for dispensing or releasing of a product contained therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A modular conveyor capable of movement in a curved path in the conveyor plane and in a curved path in a plane transverse to the conveyor plane and comprising a plurality of modules each including: a bottom wall having a first link section and a second link section pivotally interconnected for pivotal movement of said first and second sections about a normally horizontal axis transverse to the longitudinal conveyor axis; first and second end portions each pivotally connected to an end portion of an adjacent module for pivotal movement of adjacent modules about a normally vertical axis and displaced from said normally horizontal axis along the conveyor axis; and a receptacle integrally formed with said module and disposed between said end portions and including side walls having flexible portions to accommodate opening of the receptacle upon pivotal movement of the module about its normally horizontal axis.
Claim 2
Dependent Claim
146 words
A modular conveyor capable of movement in a curved path in the conveyor plane and in a curved path in a plane transverse to the conveyor plane and comprising a plurality of modules each including: a bottom wall having a first link section and a second link section pivotally interconnected for pivotal movement of said first and second sections about a normally horizontal axis transverse to the longitudinal conveyor axis; first and second end portions each pivotally connected to an end portion of an adjacent module for pivotal movement of adjacent modules about a normally vertical axis and displaced from said normally horizontal axis along the conveyor axis; and a receptacle integrally formed with said module and disposed between said end portions and including side walls having flexible portions to accommodate opening of the receptacle upon pivotal movement of the module about its normally horizontal axis.
Claim 3
Dependent Claim
96 words
The modular conveyor of claim 1 wherein each of said modules includes: a sprocket plate integral with the bottom wall and disposed symmetrically with respect to the longitudinal conveyor axis and with respect to said normally vertical axis and cooperative with a vertical sprocket wheel for movement of the modules in a vertical turn; and sprocket elements integral with the bottom wall and disposed symmetrically with respect to the longitudinal conveyor axis and with respect to said normally horizontal axis and cooperative with a horizontal sprocket wheel for movement of the modules in a horizontal turn.
Claim 4
Dependent Claim
40 words
The modular conveyor of claim 2 wherein said first and second link sections are joined for pivotal movement about said normally horizontal axis by a flex hinge integral with said bottom wall and joining said first and second link sections.
Claim 5
Dependent Claim
47 words
The modular conveyor of claim 3 wherein said receptacle includes: a plurality of walls integral with and upstanding from said bottom wall to provide a closed receptacle; and the flexible portions of said side walls being of flexible folded configuration disposed in alignment with said flex hinge.
Claim 6
Dependent Claim
65 words
The modular conveyor of claim 3 wherein said end portions extend outwardly substantially at the plane of the bottom wall along said conveyor axis, the vertical sprocket plate being integral and outwardly extending from one of said end portions; and an opening provided symmetrically through said one end portion and said sprocket plate for accommodation of a pivot pin for pivotal interconnection of adjacent modules.
Claim 7
Dependent Claim
54 words
The modular conveyor of claim 2 wherein one of said end portions has a bottom surface disposed substantially in the plane of the upper surface of the other end portion such that the one end portion of a module is disposed over the other end portion of an adjacent module and pivotally connected thereto.
Claim 8
Dependent Claim
41 words
The modular conveyor of claim 6 wherein the vertical sprocket plate is spaced from the bottom surface of said one end portion to provide a slot into which the other end portion of an adjacent module is inserted and pivotally connected.
Claim 9
Dependent Claim
63 words
The modular conveyor of claim 2 wherein said sprocket elements include: first and second pairs of elements each pair disposed on a respective side of the longitudinal axis symmetrical with respect to the longitudinal axis and with respect to said normally horizontal axis, each pair of elements being cooperative with a horizontal sprocket wheel with the module lying in a normally horizontal plane.
