Abstract
Systems for spacing and transferring objects between operative stations are provided. Such systems can be used with ovens for preforms for plastic material, in blowing or stretch-blowing machines and for other applications in the packaging field. Such systems provide spacing and transferring of objects advancing in procession on transport elements, from a minimum pitch to a preset pitch larger than said minimum pitch, and for transferring said spaced objects to handling elements.
Claims32
A system for spacing and transferring objects advancing in procession on transport elements from a minimum pitch to a preset pitch larger than said minimum pitch, and for transferring said spaced objects to handling elements, said system comprising a driving wheel, said driving wheel comprising a plurality of recesses for driving said objects, the recesses being spaced by a pitch larger than said minimum pitch of the objects in the transport elements, said pitch of the recesses being equal to or less than said preset pitch, wherein said system further comprises:
- a handling and spacing system capable of moving said objects from said minimum pitch to a pitch substantially corresponding to the pitch of the recesses, and
- a plurality of pliers radially extendible from the driving wheel, said pliers being driven by a cam profile that determines the path of said pliers, said pliers being adapted to transfer the objects to said handling elements.
