Abstract:
A device for transferring a bar from an inclined supporting surface onto an underlying channel of a guide of a bar feeder, the device including:a motorization system comprising a motorization rod; anda plurality of oscillating elements actuated by said motorization system for oscillating between a bar receiving position located at said supporting surface in which a bar arriving from said supporting surface is received in abutment and a bar deposition position in which the bar is deposited at a bottom part of the channel of the feeder guide;and wherein said oscillating elements each comprise:a bar abutment lever having an abutment edge for receiving in abutment and accompanying said bar during transfer movement thereof from said supporting surface to said underlying channel;a bar supporting lever having a central expansion constituting a supporting edge for supporting the bar during the transfer movement thereof, a front edge with a tip expansion protruding therefrom for retaining the bar arriving from the supporting surface, with said supporting edge and said front edge with the tip expansion thereof forming a bar transferring slot for accommodating and respectively transferring, along a path extending from a bar receiving position to a bar deposition position, the bar arrived from the supporting surface; anda linkage system, mounted under said supporting surface, for linking said bar supporting and abutment levers to said motorization system,wherein said linkage system comprises: a radial arm connected to said motorization rod; a first arm connected to said abutment lever; a stem, said first arm being further connected at a free end thereof, by way of said stem, to said radial arm, said motorization rod being actuatable to produce oscillation of said oscillating elements; and articulation pivots for articulating said stem to said first and radial arms respectively; andwherein said bar supporting lever and said abutment lever are operatively interconnected by way of a slot link and are further articulated to said linkage system so as to be oscillatable both together and with respect to each other through preset rotation angles, said rotation angles being such as to determine movement of said bar transferring slot with said bar accommodated therein along said path, with said supporting lever oscillating through a greater rotation angle than the rotation angle of the abutment lever.
