Abstract

Abstract A device that can be mounted on an infeed hopper of a cigarette packeting machine, for checking the soundness of the cigarettes in a pile movable along each of the exit channels of the hopper. The device comprises sensor means for checking at least two successive cigarettes per movement cycle of the pile, and at least one ejector device for individual cigarettes, this being placed downstream with respect to the sensor means, in the movement direction of the pile, and controlled by the sensor means.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 223 words
A device for checking the soundness of cigarettes fed to a cigarette packeting machine, a cigarette infeed hopper for said packeting machine, means to feed said cigarettes through said hopper in steps of one cigarette at a time in single file transversely to their axes, means to mount said checking device on said hopper, said checking device comprising a plurality of N in number of cigarette soundness sensor means, and cigarette ejector means all arranged closely adjacent the ends of said cigarettes as they move through said hopper and in predetermined spaced relation to each other with said ejector means downstream of all of said sensor mens, all N of said sensor means each performing a checking operation on each single cigarette step motion of said cigarettes through said hopper, means to coordinate the operations of all N of said sensor means and said ejector means together with the operation of said means to feed said cigarettes through said hopper to eject a faulty cigarette sensed by any one of said N number of sensor means by said ejector means, and said N number of sensor means being operative to detect and to cause said ejector means to eject (N-1) faulty cigarettes in succession and also to assure that every cigarette in said hopper will be checked as to soundness at least once.
Claim 2
Independent Claim 223 words
A device for checking the soundness of cigarettes fed to a cigarette packeting machine, a cigarette infeed hopper for said packeting machine, means to feed said cigarettes through said hopper in steps of one cigarette at a time in single file transversely to their axes, means to mount said checking device on said hopper, said checking device comprising a plurality of N in number of cigarette soundness sensor means, and cigarette ejector means all arranged closely adjacent the ends of said cigarettes as they move through said hopper and in predetermined spaced relation to each other with said ejector means downstream of all of said sensor mens, all N of said sensor means each performing a checking operation on each single cigarette step motion of said cigarettes through said hopper, means to coordinate the operations of all N of said sensor means and said ejector means together with the operation of said means to feed said cigarettes through said hopper to eject a faulty cigarette sensed by any one of said N number of sensor means by said ejector means, and said N number of sensor means being operative to detect and to cause said ejector means to eject (N-1) faulty cigarettes in succession and also to assure that every cigarette in said hopper will be checked as to soundness at least once.
Claim 3
Dependent Claim 28 words
Device according to claim 1, wherein said sensor means are able to check at least two successive cigarettes per stepping movement of said cigarettes in said hopper pile.
Claim 4
Dependent Claim 36 words
Device according to claim 1, wherein said sensor means are able to perform at least two checking operations in the same position along said cigarettes in said hopper channel per stepping movement of the said pile.
Claim 5
Dependent Claim 20 words
Device according to claim 1, wherein said hopper is substantially vertically oriented and gravity aids in feeding said cigarettes therethrough.
Claim 6
Dependent Claim 9 words
Device according to claim 1, wherein N equals two.
Claim 7
Dependent Claim 26 words
Device according to claim 5, wherein said two sensor means are separated from each other by a distance substantially equal to the diameter of one cigarette.
Claim 8
Dependent Claim 13 words
Device according to claim 1, wherein said ejector means comprise an air blower.
Claim 9
Dependent Claim 13 words
Device according to claim 1, wherein said sensor means comprise tactile pin means.
