Description

Technical Field

[0001] The utility model relates to the technical field of logistics conveying equipment, in particular to a turnover roller conveyor. Background Art

[0002] Roller conveyors are also an important type of conveying equipment in the logistics industry. They are used for sorting and classification and are suitable for the transportation of various types of boxes, packages, pallets and other pieces of goods. Bulk materials, small items or irregular items need to be placed on pallets or in turnover boxes for transportation. When emergencies such as fire occur, the fire doors need to be closed. Since some roller conveyors are located right at the fire doors, the normal lifting and lowering of the fire doors are affected.

[0003] Existing roller conveyors, such as the one disclosed in patent number CN 109823812 A, are reversible roller conveyors, which include a fixed roller frame and a reversing roller frame, both of which are equipped with conveying rollers, and the conveying drive motor drives the conveying rollers to rotate through the first transmission assembly, and the reversing roller frame is reversibly connected to one end of the fixed roller frame through the reversing shaft, and the bottoms of the fixed roller frame and the reversing roller frame are respectively provided with a plurality of first supporting legs and a second supporting leg, and a reversing drive motor is installed below the fixed roller frame, and a reversing transmission assembly is arranged between the reversing drive motor and the reversing shaft. The reversible roller conveyor can effectively avoid interference and ensure the normal operation of the conveying system when a fire shutter door falls or an escape passage is opened, which not only effectively ensures life safety, but also does not affect the normal operation of the conveying system; and the manufacturing cost is low and maintenance is convenient.

[0004] The above roller conveyor drives the turning roller frame to turn over by driving the motor, but when the driving motor fails to work normally, the turning roller frame cannot turn over in time, affecting the rapid descent of the fire door and failing to ensure the personal safety of the workers.
