Transport system, method of manufacturing the transport system

A transport system for conveying goods in a conveying direction along a conveyor belt plane of a conveyor belt, comprising:

• a) on a bearing side of the conveyor belt, at least one bearing surface for carrying the goods, the at least one bearing surface is oriented along the conveyor belt plane, and
• b) on a guiding side of the conveyor belt, at least one guide surface, oriented along the conveyor belt plane, for guiding the conveyor belt,
• c) wherein the guide surface includes a plurality of notches, wherein the notches
• d) include a plurality of guide notches, wherein a longitudinal axis of each of the guide notches is oriented along the conveying direction, and
• e) include a number of drive notches, wherein a longitudinal axis of each of the drive notches is oriented in a transverse direction, transversely to the conveying direction, and
• f) wherein the transport system includes at least one drive roller for driving the conveyor belt, which is in contact with an outer surface of the drive roller, through a rotation of the drive roller about an axis of rotation,
• g) wherein the outer surface includes a plurality of ridges,
• h) wherein the ridges include a number of drive ridges that engage in the drive notches for driving the conveyor belt along the conveying direction, wherein a longitudinal axis of each of the drive ridges is oriented along the axis of rotation,
• i) wherein the ridges include a plurality of guide ridges that engage in the guide notches for guiding the conveyor belt along the conveying direction, wherein each of the guide ridges extends about the axis of rotation in the circumferential direction of the drive roller,
• j) wherein at least one of the guide notches of the conveyor belt, and the guide ridge of the drive roller engaging therein, are configured such that mechanical transverse play in the transverse direction exists between the guide notch and the guide ridge, without transverse stressing of the conveyor belt in the transverse direction, wherein at least one of the notches includes:
• a) at least one base surface for limiting a penetration depth of the guide ridge or drive ridge into the conveyor belt, and
• b) at least one left flank surface, arranged obliquely to the conveyor belt plane, and connecting the guide surface with the base surface, and
• c) at least one right flank surface, arranged obliquely to the conveyor belt plane, and connecting the guide surface with the base surface, wherein
• d) a base width of the base surface, perpendicularly to the longitudinal axis of the notch, is smaller than an opening width of the notch perpendicularly to the longitudinal axis of the notch and in a plane with the guide surface.
