Abstract
Abstract A system and process for sorting and opening packages particularly suitable for reclaiming reusable, returned goods. The system and process separates unusable returned goods from reusable returned goods, and gathers information and data on the goods which information can be of benefit to management. The system and process provides for optically reading the Universal Product Codes on the packages of reusable and unusable goods. Based on this UPC code identification, the packages are segregated into categories of reusable and unusable goods. The system and process further segregates the reusable goods into various different types of reusable goods based on predetermined criteria. The system and process even further provides for automatically opening the packages containing reusable goods, and separating the goods from the opened packages.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
141 words
A system for sorting packages, comprising: means for conveying the packages to be sorted; Universal Product Code reading means located at a preselected location at the conveyor means for reading the Universal Product Code on each of the packages being conveyed on the conveyor means; processor means operatively associated with the Universal Product Code reading means for receiving the signal representing the Universal Product Code from the reading means and comparing the Universal Product Code with stored information related to the Universal Product Code; first ejector means operatively associated with the processor means for ejecting packages not identified by the processor means from the conveyor means; and, detection means located at the conveyor means downstream of the first ejector means for determining if a package selected for ejection by the first ejector means was in fact ejected from the conveyor means.
Claim 2
Independent Claim
141 words
A system for sorting packages, comprising: means for conveying the packages to be sorted; Universal Product Code reading means located at a preselected location at the conveyor means for reading the Universal Product Code on each of the packages being conveyed on the conveyor means; processor means operatively associated with the Universal Product Code reading means for receiving the signal representing the Universal Product Code from the reading means and comparing the Universal Product Code with stored information related to the Universal Product Code; first ejector means operatively associated with the processor means for ejecting packages not identified by the processor means from the conveyor means; and, detection means located at the conveyor means downstream of the first ejector means for determining if a package selected for ejection by the first ejector means was in fact ejected from the conveyor means.
Claim 3
Dependent Claim
35 words
The system of claim 1, further comprising sorting means located at a preselected location at the conveyor means downstream of the first ejector means for sorting packages remaining on the conveyor means into different categories.
Claim 4
Dependent Claim
29 words
The system of claim 2, wherein the sorting means is operatively associated with the processor means for sorting the packages into different categories based on the Universal Product Code.
Claim 5
Dependent Claim
26 words
The system of claim 2, further comprising second conveyor means downstream of the sorting means for separately conveying each of the different categories of sorted packages.
Claim 6
Dependent Claim
20 words
The system of claim 2, further comprising means for severing each of the sorted packages downstream of the sorting means.
Claim 7
Dependent Claim
24 words
The system of claim 5, wherein the package severing means comprises means for directing a jet of liquid against the packages to be severed.
Claim 8
Dependent Claim
45 words
The system of claim 2, further comprising package aligning means for aligning the packages on the conveying means upstream of the Universal Product Code reading means in a first orientation so that the Universal Product Code is exposed to the Universal Product Code reading means.
Claim 9
Dependent Claim
28 words
The system of claim 7, further comprising second package aligning means for aligning the packages sorted into different categories in a second orientation in preparation for being severed.
Claim 10
Dependent Claim
34 words
The system of claim 1, further comprising second ejector means operatively associated with the detector means for ejecting the packages previously selected for ejection by the first ejector means but which were not ejected.
Claim 11
Dependent Claim
27 words
The system of claim 1, wherein the detection means comprises photocell means for determining if a package selected for ejection by the first ejector means was ejected.
Claim 12
Dependent Claim
26 words
The system of claim 10, further comprising means for activating the photocell means in timed relationship to the movement of the packages on the conveyor means.
Claim 13
Dependent Claim
19 words
The system of claim 1, further comprising means for slitting open each of the packages on the conveyor means.
Claim 14
Dependent Claim
27 words
The system of claim 12, wherein the package slitting means comprises means for directing a jet of liquid against each of the packages to slit them open.
