1. An apparatus for placing products into blisters of a blister band moved in a forward motion direction along a blistering machine, with blisters made in an upper surface of said blister band and made accessible from top, the apparatus having at least one work unit, situated above said blister band, the work unit including:
a carriage carried by a support, connected to a bearing structure of said blistering machine, with the carriage capable of sliding, with respect to the support, parallel to the blister band forward motion direction;
at least one hopper, carried by said carriage, fed with products and feeding said products to at least one discharge conduit fastened to said carriage, the discharge conduit having a lower end situated directly above the upper surface of said blister band and aligned with respect to a corresponding longitudinal row of blisters made in the latter;
first means for operating said carriage between two extreme positions, a rear position and a fore position, by a forward stroke and return stroke, with the forward stroke being operated in step relation with advancement of said blister band, so as to center the lower end of said discharge conduit with respect to a corresponding blister of said row, situated below and to maintain this centering for a prefixed period of time;
at least one moving assembly, connected to said carriage and carrying a strip interposed between said lower end of at least one discharge conduit and the upper surface of the blister band, and extending forward with respect to the band forward motion direction, said strip having at least one hole, which is aligned with the longitudinal row of blisters and whose size allows single products to pass therethrough;
second means for moving said strip parallel to the blister band forward motion direction, in step relation with the operation of said carriage, thus performing a forward stroke and a return stroke, between two extreme positions, a rest position and a working position, with the rest position preventing the lowermost product of the pile of products contained in said conduit from falling, and with the working position, defined by said forward stroke, allowing the centering of the hole with the lower end of said conduit, situated above, and consequently, allowing the said lowermost product to fall into said blister, during said time period.
2. An apparatus, as claimed in claim 1, further including a least two work units, provided with hoppers containing different kinds of products, which can be fed by means of respective discharge conduits to corresponding blisters of said blister band.
3. An apparatus, as claimed in claim 2, wherein the length of the strips of said work units is such as to cover longitudinally and continuously the filling area of said blister band.
4. An apparatus, as claimed in claim 2, wherein the carriages of said work units are moved in synchrony.
5. An apparatus, as claimed in claim 3, wherein the carriages of said work units are moved in synchrony and said strips are also moved in synchrony.
6. An apparatus, as claimed in claim 2, wherein the carriages of said work units are moved asynchronously.
7. An apparatus, as claimed in claim 3, wherein the carriages of said work units are moved asynchronously and said strips are moved asynchronously.
8. An apparatus, as claimed in claim 1, wherein said strip matches with the upper surface of said blister band.
9. An apparatus, as claimed in claim 3, wherein said strips match with the upper surface of said blister band.
10. An apparatus, as claimed in claim 1, wherein the hopper of said at least one work unit includes at least two separate chambers fed with different products and feeding these products to corresponding discharge conduits.
11. An apparatus, as claimed in claim 1, wherein the moving assembly carrying said strip also carries a first arm, with an upstream end of the strip fastened to said arm.
12. An apparatus, as claimed in claim 11, wherein said moving assembly supports a second arm, situated downstream of the first arm, with respect to the blister band forward motion direction, and having suction means for raising, when operated, the strip below when the work unit in cleaning andor maintenance configuration.
13. An apparatus, as claimed in claim 3, wherein the length of said strips is such, as to cause partial superimposing of the strips, at least in a configuration of minimum mutual distance between the respective units.
14. An apparatus, as claimed in claim 1, wherein the support of each of said units moves vertically, for raising the respective unit with respect to the blister band, when the unit is inoperative.
15. An apparatus, as claimed in claim 1, wherein said hopper slides vertically with respect to the carriage and that said discharge conduit, fastened to the carriage, is freely introduced into a hole made in the bottom of the hopper, with means being provided for operating the hopper to move vertically with a vibratory motion, so as to allow the products contained therein to be enter to the discharge conduit.
16. An apparatus, as claimed in claim 1, wherein the fore stroke of said moving assembly is discordant with respect to the blister band forward motion direction.
17. An apparatus, as claimed in claim 2, wherein said units are carried by only one support.
18. An apparatus, as claimed in claim 1, wherein said moving assembly is carried, sliding, by guides made in the carriage, parallel to the band forward motion direction.
