Device for transferring products between moulds of a production machine and a table of a wrapping machine

Claim 1

Apparatus for removing tablets of chocolate from their respective molds as they issue from a production machine moving horizontally in mutually spaced relationship and transferring them to horizontal conveyor in a plane different from the plane of said path comprising a hollow shaft, cup supports, tubular arms mounting said cup supports for rotation about said shaft on opposite radii thereof in a path successively intersecting the moving tablets issuing from the production machine and said conveyor, means for driving said arms in synchronism with the spacing of said tablets issuing from said machine, means responsive to the angular position of said cups to provide vacuum to them from their intersection with said tablets issuing from said machine until intersection with said conveyor so as to suck up said tablets from said molds to hold them during angular transfer and to free them as they are supported by said conveyor, first cam means driven with said arms to impart to the cup supports an angular correction with respect to the radius of said shaft, in order to keep the longitudinal axis of the suction cups in a vertical position from the beginning of said suction zone until a locus beyond said suction zone, and furthermore in order to turn said axis around an angle of 180° and keep the axis in a vertical position from the beginning of a zone where the tablets or bars are given over to said conveyor until a locus beyond said last mentioned zone, and second cam means driven with said arms to move said arms parallel to the fixed shaft during their rotation in order to control the spacing of the tablets or bars during their transfer from said molds to said conveyor.
