Abstract
Abstract Apparatus for selectively destroying improperly coded cartons in a series of cartons moving through a folding and gluing machine, comprising a code reader mounted on the machine to sense coded indicia on cartons and a cutter activated by the code reader when it senses an improper code, and synchronized to intercept and sever an element of the improperly coded carton, thus rendering the carton unusable while permitting the remainder of the severed carton to proceed without disturbing the properly coded cartons as they pass together through the machine, the miscoded carton being severed in a manner to insure that a portion of the severed carton will extend from the stack of completed cartons as the stack leaves the machine to provide for flagging of improperly coded cartons.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
Apparatus for use with high speed conveyor means for transporting a series of folding carton blanks from a stack of such blanks to a station for further processing, each of the blanks having a predetermined portion essential to the erection of the blank into a useable carton and having coding indicia formed on said portion, said apparatus comprising means for generating a signal in response to the coding indicia on said portion as it passes a predetermined point adjacent the conveyor means, means operative in response to the signal generated for selectively destroying the predetermined portion of any carton passing said point from which carton a predetermined signal has not been generated without altering the position of any carton blank on the conveyor means.
Claim 2
Dependent Claim
124 words
Apparatus for use with high speed conveyor means for transporting a series of folding carton blanks from a stack of such blanks to a station for further processing, each of the blanks having a predetermined portion essential to the erection of the blank into a useable carton and having coding indicia formed on said portion, said apparatus comprising means for generating a signal in response to the coding indicia on said portion as it passes a predetermined point adjacent the conveyor means, means operative in response to the signal generated for selectively destroying the predetermined portion of any carton passing said point from which carton a predetermined signal has not been generated without altering the position of any carton blank on the conveyor means.
Claim 3
Dependent Claim
144 words
Apparatus for use with high speed conveyor means for transporting a series of folding carton blanks from a stack of such blanks to a station for further processing, each of the blanks having a predetermined portion essential to the erection of the blank into a useable carton and having coding indicia formed on said portion, said apparatus comprising means for sensing the coding indicia on each carton, means operatively connected to said sensing means and programmed to distinguish a preselected coding indicia on said cartons sensed by said sensing means and to change state in response to the absence of said preselected coding indicia on at least one of said cartons and means operatively connected to said programmed means for selectively destroying said predetermined portion in response to said change of state without altering the position of any carton blank on the conveyor means.
Claim 4
Dependent Claim
144 words
Apparatus for use with high speed conveyor means for transporting a series of folding carton blanks from a stack of such blanks to a station for further processing, each of the blanks having a predetermined portion essential to the erection of the blank into a useable carton and having coding indicia formed on said portion, said apparatus comprising means for sensing the coding indicia on each carton, means operatively connected to said sensing means and programmed to distinguish a preselected coding indicia on said cartons sensed by said sensing means and to change state in response to the absence of said preselected coding indicia on at least one of said cartons and means operatively connected to said programmed means for selectively destroying said predetermined portion in response to said change of state without altering the position of any carton blank on the conveyor means.
Claim 5
Dependent Claim
47 words
The apparatus of claim 2 further comprising means for controlling the operation of said selective destroying means in response to said change of state to insure the destruction of only those cartons which pass said sensing means and cause a change of state in said programming means.
Claim 6
Dependent Claim
27 words
The apparatus of claim 3 wherein said selective destroying means comprises a cutting means for removing the portion of the carton on which the indicia is formed.
Claim 7
Dependent Claim
50 words
The apparatus of claim 4 wherein said cutting means is mounted adjacent to said conveyor means, spaced along the direction of movement of said carton blanks on said conveyor from said sensing means and said predetermined portion of said carton blanks comprises a glue flap hingedly connected to said blank.
Claim 8
Dependent Claim
19 words
Apparatus according to claim 5 wherein said controlling means comprises means for delaying the operation of said cutting means.
Claim 9
Dependent Claim
21 words
The apparatus of claim 6 wherein said controlling means comprises a time delay means syncronized with the speed of said conveyor.
