<p>The present invention relates to a system for spacing and transferring objects between operative stations. In particular, the invention is applied to an oven for preforms in plastic material, usable moreover, without limitation, in blowing or stretch-blowing machines. In particular, the present invention relates to a system for spacing and transferring objects (P) advancing in procession on transport means, from a minimum pitch to a preset pitch larger than said minimum pitch, and for transferring said spaced objects to handling means, wherein said system comprises a driving wheel (15'), said driving wheel (15') comprising a plurality of recesses (26) for driving said objects, the recesses (26) being spaced by a pitch larger than said minimum pitch of the objects in the transport means, said pitch of the recesses (26) being equal to or lower than said preset pitch, wherein the system comprises:
- handling and spacing means (44b) of the objects from said minimum pitch to a pitch substantially corresponding to the pitch of the recesses (26), and
- a plurality of pliers (50) for the objects radially extendible from the driving wheel (15'), said pliers (50) being driven by a cam profile (55, 55') that determines the path of said pliers (50) and being adapted to transfer the objects to said handling means.</p> |
