A conveying and sorting apparatus has a plurality of tilting conveyor units in a row in the conveying direction. Each tilting conveyor unit is able to switch between a horizontal conveying orientation and a tilted orientation for ejecting the object being conveyed, by means of gravity, laterally with respect to the conveying direction and has a belt conveyor with a plurality of ridge portions which extend in the width direction on the inside surface, and on the outside surface the ridge portions which extend in the width direction are provided an equivalent intervals in the length direction of the belt. A plurality of recessed grooves which engage with each of the ridge portions on the inside surface of the belt are provided to the peripheral surfaces of a front pulley and a rear pulley of the belt.

A net chain driving structure includes a conveying net chain. The conveying net chain includes a plurality of chain links successively inserted in a conveying direction, a plurality of lugs spaced apart from each other are arranged on two sides of the chain links, an end portion of the lug is an arcuate face, a meshing groove is disposed on the chain link, the meshing groove is spliced by an open slot provided on a back side of the chain link and the lugs on the adjacent chain links, a gear in transmission meshing with the meshing groove is disposed on each end of the conveying net chain, a tangent plane tangential to the arcuate face is disposed on the arcuate face of the lug, and transmission contact toothed surfaces of the tangent plane and the gear are attached to each other in parallel during meshing transmission.

According to one aspect of the present invention, an accumulation module for a product delivery system includes an input shaft configured to receive an external drive force. A transfer shaft reverses an operation of the external drive force to define a reversing drive force. An output shaft receives the reversing drive force. An accumulation belt is operated by the reversing drive force. The accumulation belt operates in opposition to the external drive force.

A modular conveyor belt module includes a base body extending along a first direction transverse with respect to the transport direction, between two opposite lateral faces. The module includes upper and lower surfaces; two opposed longitudinal edges; hinge elements projecting respectively from the two edges along a second direction. Each of the first and second hinge elements is crossed by a first and second hole, respectively, the axes of the holes being parallel to the first direction. The holes are each coaxial to each other. The first hinge elements interpose the second hinge elements of another module with the respective holes coaxially aligned. The hinge elements are interposed to each other leaving free spaces to receive a roller. Each roller projects with a portion from the upper surface, the plane parallel with respect to the two directions and tangent to the portion of the rollers projecting from the upper surface.
