Abstract
A conveyor for conveying piece goods or the like through a helical path around a central axis in a vertical direction includes a frame which supports an endless conveyor belt that is movable along the helical path in a conveying direction. The conveyor belt includes carrier plates which are movably connected to each other. The frame includes at least a guide and at least a number of carrier plates comprise at least a guide roller rotatable about an axis of rotation. The guide roller has at least a first guide roller surface which is in contact with the guide in a first contact location, and a second guide roller surface which is in contact with the guide in a second contact location. The first and second contact locations are spaced from each other and the normal to the first guide roller surface in the first contact location deviates from the normal to the second guide roller surface in the second contact location. The invention provides a conveyor with a high driving efficiency as a consequence of low resistance between the carrier plate and the guide.
