Conveyor system

A conveyor system that transports a plurality of pallets that are closely placed on a transport path, comprising:

• at least two driving devices that each has an engaging portion to be engaged with, of the plurality of pallets, the pallet located at an upstream-side end portion in a pallet transport direction, and that each moves the engaging portion toward a downstream side in the pallet transport direction in a state where the engaging portion is engaged with the pallet located at the upstream-side end portion to thereby simultaneously push the plurality of pallets;
• and
• a plurality of transport portions on which the plurality of pallets are mounted and that are coupled in series to form the transport path and are able to transport the plurality of pallets pushed by the driving devices,
• wherein the conveyor system is configured to transport the plurality of pallets at a constant speed by repeating engaging the engaging portion of one of the driving devices with the pallet located at the upstream-side end portion in the pallet transport direction and causing the one of the driving devices to start pushing the plurality of pallets by the time when another one of the driving devices completes pushing the plurality of pallets, and
• the conveyor system is configured so that a length of the conveyor system can be changed by adding or removing at least one of the transport portions.
