Conveyor system having a lateral take-off conveyor for flat products, especially paper products

Claim 2

A conveyor system for substantially flat products, especially paper products, comprising: an infeed conveyor for conveying the products in a first predetermined direction of travel; said infeed conveyor having a discharge end; an outfeed conveyor for conveying the products in a second predetermined direction of travel; said outfeed conveyor traveling past the discharge end of the infeed conveyor and at an angle with regard to said first predetermined direction of conveying of the products; a number of essentially conical clamping bodies each having a lengthwise axis and operatively associated with said outfeed conveyor; means for mounting said essentially conical clamping bodies to be rotatable about their related lengthwise axis; said mounting means arranging said essentially conical clamping bodies in succession in the second direction of conveying of the outfeed conveyor and in spaced relationship from the discharge end of the infeed conveyor; each of said clamping bodies having a tip directed towards the direction of conveying of the infeed conveyor; each of said clamping bodies having an outer surface; said outer surfaces of said clamping bodies together with the outfeed conveyor forming a respective product conveying gap which is effective in the second direction of conveying of the outfeed conveyor; and the spacing of the successive clamping bodies increasing from the discharge end of the infeed conveyor in the conveying direction of the outfeed conveyor, said spacing being measured in a plane parallel to the conveying direction of and perpendicular to the plane of the outfeed conveyor.

Claim 3

The conveyor system as defined in claim 1, wherein: each of said essentially conical clamping bodies has a region of largest diameter which frictionally bears at the outfeed conveyor and is thereby driven by such outfeed conveyor.

Claim 4

The conveyor system as defined in claim 1, wherein: said mounting means for said clamping bodies incorporates mechanism for adjusting the clamping bodies in the direction of their axes and fixedly positioning the thus adjusted clamping bodies, so that the increase of the spacing from the discharge end of the infeed conveyor in the second direction of conveying of the outfeed conveyor can be altered.

Claim 5

A conveyor system for substantially flat products, especially paper products, comprising: an infeed conveyor for conveying the products in a first predetermined direction of travel; said infeed conveyor having a discharge end; an outfeed conveyor for conveying the products in a second predetermined direction of travel; said outfeed conveyor traveling past the discharge end of the infeed conveyor and at an angle with regard to said first predetermined direction of conveying of the products; a number of essentially conical clamping bodies each having a lengthwise axis and operatively associated with said outfeed conveyor; means for mounting said essentially conical clamping bodies to be rotatable about their related lengthwise axis; said mounting means arranging said essentially conical clamping bodies in succession in the second direction of conveying of the outfeed conveyor and in spaced relationship from the discharge end of the infeed conveyor; each of said clamping bodies having a tip directed towards the direction of conveying of the infeed conveyor; each of said clamping bodies having an outer surface; said outer surfaces of said clamping bodies together with the outfeed conveyor forming a respective product conveying gap which is effective in the second direction of conveying of the outfeed conveyor; the spacing of the successive clamping bodies increasing from the discharge end of the infeed conveyor in the conveying direction of the outfeed conveyor; said plurality of essentially conical clamping bodies including two substantially axially parallel clamping bodies; balance beam means; means for oscillatingly suspending said balance beam means about an axis extending essentially parallel to the first direction of conveying of the infeed conveyor; said balance beam means having end portions; and one respective clamping body being mounted at each said end portion of said balance beam means.

Claim 6

A conveyor system for substantially flat products, especially paper products, comprising: an infeed conveyor for conveying the products in a first predetermined direction of travel; said infeed conveyor having a discharge end; an outfeed conveyor for conveying the products in a second predetermined direction of travel; said outfeed conveyor traveling past the discharge end of the infeed conveyor and at an angle with regard to said first predetermined direction of conveying of the products; a number of essentially conical clamping bodies each having a lengthwise axis and operatively associated with said outfeed conveyor; means for mounting said essentially conical clamping bodies to be rotatable about their related lengthwise axis; said mounting means arranging said essentially conical clamping bodies in succession in the second direction of conveying of the outfeed conveyor and in spaced relationship from the discharge end of the infeed conveyor; each of said clamping bodies having a tip directed towards the direction of conveying of the infeed conveyor; each of said clamping bodies having an outer surface; said outer surfaces of said clamping bodies together with the outfeed conveyor forming a respective product conveying gap which is effective in the second direction of conveying of the outfeed conveyor; the spacing of the successive clamping bodies increasing from the discharge end of the infeed conveyor in the conveying direction of the outfeed conveyor; said plurality of essentially conical clamping bodies including two substantially axially parallel clamping bodies; balance beam means; means for oscillatingly suspending said balance beam means about an axis extending essentially parallel to the first direction of conveying of the infeed conveyor; said balance beam means having end portions; and one respective clamping body being mounted at each said end portion of said balance beam means.

Claim 7

The conveyor system as defined in claim 4, wherein: said infeed conveyor has lateral oppositely situated edges; and each clamping body of said two clamping bodies being aligned with their related lengthwise axis essentially in the direction of a related one of the lateral edges of the infeed conveyor.

Claim 8

The conveyor system as defined in claim 4, further including: means for adjusting and fixing in adjusted position the balance beam means in the first direction of conveying of the infeed conveyor.

Claim 9

The conveyor system as defined in claim 4, further including: rocker means having a first end and second end; means for articulating said balance beam means between its end portions at the first end of said rocker means; means defining a stationary overhang arm means; means for hingedly connecting the other end of said rocker means at said stationary overhang arm means; said means for articulating the balance beam means at the first end of the rocker means and the means for hingedly connecting the other end of said rocker means at said stationary overhang arm means comprise pivot means having axes extending essentially parallel to the lengthwise axes of the clamping bodies.

Claim 10

The conveyor system as defined in claim 7, wherein: said means for hingedly connecting the second end of said rocker means at said stationary overhang arm means comprises pivot means; and means for displacing and fixing in position said pivot means at said overhang arm means in the first direction of conveying of the infeed conveyor.
