Device for picking up semi-rigid sheet-like elements from a magazine and transferring them onto a conveyor

A device for picking up semirigid sheet-like elements from a magazine, characterized in that it comprises a rotating body driven of continuous motion and supported by a normally horizontal and fixed shaft, a radial cam mounted on said shaft and fixed with respect to said rotating body, at least one arm mounted on said shaft for oscillation in a plane normal thereto and serving as a radial guide for an attaching block of a gripping member for the sheet-like elements contained in the magazine, a planet gear carried idly by said arm and provided with an eccentric pin for engagement with said radial cam, said planet gear meshing with a gear segment rigid with said rotating body and concentrical with said shaft, and a cam provided on said rotating body at said gear segment and being engaged by a pin projecting from said block for defining the displacement of the block between a position wherein the gripping member is spaced apart from the magazine and a position wherein said gripping member is approached thereto to pick up said sheet-like elements, said radial cam being contoured such as to cause an advanced oscillatory movement of said arm prior to the latter reaching the magazine and the stopping of said arm with respect to the magazine when the gripping member is in its position of sheet-like element picking up.
