Abstract
The device comprises two facing parallel walls and a back wall, which forms a stacking station where two facing pairs of series of discs, which form eccentrics, act on related rings, which feature teeth, which in turn work alternately and in conjunction with one another to lift and pile up blister packs supplied to the station by a feed line, and ears fitted with arms in order to control the rotation of the rings. Two pairs of belts featuring segments pick up the pile of blister packs from the station, lifting it up, and then two further pairs of belts lift the pile in their turn, conveying it out of the device.
Claims9
A device for forming a pile of blister packs and moving said pile in an upward direction, said device comprising:
- a support structure;
- a feed line for blister packs;
- a station for collecting said blister packs, said station being formed by two facing vertical side walls, and a vertical back wall, with said side and back walls mounted on said structure and with said line ending between said vertical side walls;
- first means for supporting and stacking said blister packs, said first means being located inside said vertical side walls;
- facing first and second pairs of eccentric means, each pair of said eccentric means being identical in construction and reciprocally staggered by an equal number of degrees, with an axis of each pair of said eccentric means being parallel to the direction by which said blister packs enter said station;
- a ring for each one of said eccentric means mounted thereon;
- each ring defining a tooth;
- an eccentric means from each of said first and second pairs of eccentric means forming facing first and second groups, said first and second groups alternating cyclically with one another following a series of positions located at different levels from one another, in a first stage said teeth of said first group protruding in an upward direction so as to engage with the edges of a blister pack located in said station and raise said blister pack while said teeth belonging to said second group move in a downward direction, and in a second stage said teeth belonging to said first group moving in a downward direction thus causing said blister pack to be released upon a second blister pack picked up from said line and supported by said teeth of said second group, with said teeth of said second group projecting in an upward direction, or else, if there is no blister on said teeth of said second group, said blister pack is directly released upon said teeth of said second group.
