Conveying device

A conveying device, comprising:

• a guideway including a pair of guide rails arranged parallel to each other and extending between a first position and a second position, the guide rails defining a direction of conveyance between the first and the second positions;
• a carrying device extending between the guide rails and movably supported on the guide rails so as to be displaceable along the guide rails in the direction of conveyance;
• a pulling mechanism carrier arranged between the pair of guide rails and extending between the first and the second position;
• a pulling mechanism movably supported by the pulling mechanism carrier and spaced apart from the guide rails, the pulling mechanism extending between the first and the second positions and being configured to pull the carrying device along the guide rails in the direction of conveyance;
• and
• at least one permanent magnet configured to connect the carrying device to the pulling mechanism via a magnetic attraction force between the permanent magnet and the pulling mechanism,
• wherein the permanent magnet is positioned on the carrying device, and
• wherein the pulling mechanism is a belt that is rotatably supported by the pulling mechanism carrier and that includes magnetic material,
• wherein the at least one permanent magnet defines a contact face on the carrying device,
• wherein the belt has an outer belt face that is drawn into contact with the contact face of the carrying device by the magnetic attraction force generated by the permanent magnet, and
• wherein the outer belt face of the belt and the contact face of the carrying device are configured to have a predetermined coefficient of friction that enables the outer belt face and the contact face to slide over one another when a predetermined pulling force acting on the carrying device is exceeded.
