Conveyor device for conveyor installations, a modular system, and a method for producing such a conveyor device

A conveyor for conveyor systems for conveying containers, pallets and the like, or bulk material, comprising:

• a drum tube which extends along a longitudinal axis and has a first end and a second end opposite said first end;
• an electrical drive unit which is designed to exert a conveyor torque from a first axle onto the drum tube, wherein a drive cartridge comprising a cartridge tube secured torque-resistantly and coaxially in the drum tube;
• and
• a cover rotatably mounted on the first axle and which covers one end of the cartridge tube,
• wherein the electrical drive unit is arranged inside the cartridge tube and said cartridge tube is secured coaxially inside the drum tube.

A modular system for constructing a conveyor of a desired length, in particular a conveyor according to any one of the preceding claims, said system comprising:

• a drum tube which can be produced with a desired length and having a first end and a second end opposite said first end;
• a drive cartridge comprising a cartridge tube which is designed to be received torque-resistantly into the drum tube;
• a cover which is rotatably mounted on a first axle and which covers one end of the cartridge tube;
• and
• a drive unit for exerting a conveyor torque from the first axle onto the drum tube arranged coaxially inside the cartridge tube;
• wherein
• the cartridge tube has an insert cover at one end, which is rotatably mounted on a second axle by means of a rolling bearing, wherein said second axle has a recess at the end face of the cartridge tube for torque-resistantly receiving a stub shaft.

A method for producing a conveyor, said method comprising the steps of:

• providing a drum tube which extends along a longitudinal axis and has a first end and a second end opposite said first end, and wherein the drum tube is provided with a length depending on the desired length of the conveyor;
• providing a drive cartridge comprising a cartridge tube which is designed to be received torque-resistantly and coaxially into the drum tube, and a cover which is rotatably mounted on a first axle and which covers one end of the cartridge tube;
• and
• inserting the cartridge tube into the drum tube through the second end until the cover abuts the second end of the drum tube.
