| 摘要 |
The present invention relates to an elevator for vending machines comprising a flat vertical chassis with two longitudinal guide profiles and an end transverse bridge; two pairs of gear wheels that are coaxial and coplanar to one another in twos, which are assembled in the guide profiles, two endless belts assembled between each pair of gear wheels, and a horizontal transverse tray assembled between coinciding sections of the two belts. The wheels of each pair of gear are connected by means of a shaft connected to a gear motor featuring an encoder. The tray has on its sides two freely rotating rear wheels located at different heights, housed in the guide profiles. The guide profiles have a lower stop and a front mouth located above the stop through which the lower wheels exit when the said wheels rest in the mentioned stops, causing the tray to swivel to a lower vertical overturning unloading position. The chassis furthermore has upper and lower microswitches to define the travel of the tray.
