Conveying system for shock-sensitive items, in particular eggs

A conveying system for shock-sensitive items, comprising at least a first conveying device, having a substantially horizontal orientation, and a second conveying device, having at least a first, upwardly moving section, which has a substantially vertical orientation and along which the items are advanced in an upward direction, wherein the second conveying device comprises a plurality of seats to receive the items, wherein the second conveying device is arranged so that the upwardly moving section faces an end of the first conveying device and is aligned thereto, whereby the items are transferred from the first conveying device to the seats of the second conveying device, wherein the conveying system is provided with a motion transmission assembly which is arranged between the first and the second conveying devices to transmit motion from one to the other of the conveying devices, the motion transmission assembly comprising:

• a first, driving shaft, which receives motion from the one of the conveying devices;
• a second, driven shaft, mounted on the other one of the conveying devices;
• a first pinion, mounted on the first, driving shaft;
• a second pinion, mounted on the second, driven shaft;
• a transmission chain, mounted between the first pinion and the second pinion;
• wherein:
• the first, driving shaft has a polygonal cross-section;
• the second, driven shaft has a polygonal cross-section, with the same number of sides as the cross-section of the first, driving shaft;
• the first pinion has a number of teeth equal to the number of sides of the cross-section of the first, driving shaft;
• the second pinion has a number of teeth equal to the number of teeth of the first pinion or to a multiple thereof.
