Abstract
Abstract Apparatus for identifying containers comprises a memory in which data relating to physical characteristics of containers is stored, a conveyor for transporting containers through a scanning station comprising a plurality of light detectors and a light source and signal generating means for generating signals distinguishing between those detectors obscured from said source by a container passing through said station and those not so obscured and means for comparing those signals with said data to identify the container. There is also disclosed a method of identifying containers utilizing such apparatus.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
144 words
A method for automatic recognition of containers of varying size and shape comprising storing data related to container sizes and shapes in a memory unit, transporting containers to be recognized along a transport path at a first speed, disposing a light receiving unit comprising a plurality of receivers on one side of said path, directing a narrow beam of light from the other side of said path to fall on said light receiving unit, causing said light beam to strike each receiver sequentially, repeating said process of causing said light beam sequentially to strike each receiver, cyclically at a rate directly related to said first speed, generating, in a form compatible with said data, signals distinguishing between those receivers obscured by a container passing said light receiving unit and those not so obscured and comparing said signals with said data to identify that container.
Claim 2
Independent Claim
144 words
A method for automatic recognition of containers of varying size and shape comprising storing data related to container sizes and shapes in a memory unit, transporting containers to be recognized along a transport path at a first speed, disposing a light receiving unit comprising a plurality of receivers on one side of said path, directing a narrow beam of light from the other side of said path to fall on said light receiving unit, causing said light beam to strike each receiver sequentially, repeating said process of causing said light beam sequentially to strike each receiver, cyclically at a rate directly related to said first speed, generating, in a form compatible with said data, signals distinguishing between those receivers obscured by a container passing said light receiving unit and those not so obscured and comparing said signals with said data to identify that container.
Claim 3
Dependent Claim
20 words
Method as claimed in claim 1 which comprises transmitting light received by aid receivers to a common signal generating means.
Claim 4
Dependent Claim
16 words
A method as claimed in claim 2 wherein said light is transmitted along optically conductive fibers.
Claim 5
Dependent Claim
30 words
A method as claimed in claim 1 in which said light beam is caused to strike each receiver sequentially by directing light from a source to a rotating reflecting unit.
Claim 6
Dependent Claim
20 words
A method as claimed in claim 1 wherein a laser beam is generated and is used as the light beam.
Claim 7
Independent Claim
156 words
A device for automatic recognition of containers of varying size and shape comprising transport means for transporting containers along a transport path, a light receiving unit comprising a plurality of individual receivers disposed on one side of said path, means directing a narrow beam of light across said path to fall upon said light receiving units, light beam directing means for transversing said beam of light across said light receiving unit to strike each receiver sequentially, means causing said light beam directing means to be operated cyclically at a rate directly related to the speed of operation of said transport means, means generating signals distinguishing between those receivers obscured by a container passing along said transport path and in front of said light receiver unit and those no so obscured, a memory for storing data relating to containers and means for comparing signals generated by said means for generating signals with data stored in said memory.
Claim 8
Independent Claim
156 words
A device for automatic recognition of containers of varying size and shape comprising transport means for transporting containers along a transport path, a light receiving unit comprising a plurality of individual receivers disposed on one side of said path, means directing a narrow beam of light across said path to fall upon said light receiving units, light beam directing means for transversing said beam of light across said light receiving unit to strike each receiver sequentially, means causing said light beam directing means to be operated cyclically at a rate directly related to the speed of operation of said transport means, means generating signals distinguishing between those receivers obscured by a container passing along said transport path and in front of said light receiver unit and those no so obscured, a memory for storing data relating to containers and means for comparing signals generated by said means for generating signals with data stored in said memory.
Claim 9
Dependent Claim
21 words
A device as claimed in claim 6 wherein said light receivers each comprise an end portion of an optically conductive fiber.
Claim 10
Dependent Claim
26 words
Apparatus as claimed in claim 7 wherein ends of said optical fibers remote from said light receiving ends are disposed adjacent a common signal generating element.
Claim 11
Dependent Claim
17 words
A device as claimed in claim 7 wherein said light directing means comprises a rotating reflector unit.
Claim 12
Dependent Claim
27 words
A device as claimed in claim 9 wherein said reflector unit comprises an element having a polygonal cross section, at least one face of which is reflective.
Claim 13
Dependent Claim
30 words
A device as claimed in claim 6 comprising a connection between a drive mechanism of said transport means and said means causing said light directing means to be operated cyclically.
Claim 14
Dependent Claim
31 words
A device as claimed in claim 6 wherein a common drive means is provided for said transport means and for said means causing said light directing means to be operated cyclically.
