  • Patent number: 6114636
    Abstract: The capsules or other products (1) are fed by a vertically arranged tube-shaped conveyor (4, 5, 10, 11, 12, 112, 13) in single file and taken up one at a time by a tangential wheel (16) which is fitted with reference teeth (18), with each tooth supporting one product, and has suction holes (19) to retain the products. When the products are about to reach a position above suitably shaped associated weighing heads (24), the suction that holds them against the wheel is cut off and the products fall, positioning themselves correctly on the heads, aided in part by the halting action exerted by the teeth in front. The products deposited on the heads are weighed and are then discharged by the pushing action of the wheel teeth (18) which place the next product on the heads. A chute (25) collects the products ejected from the heads and a deflection plate (26), controlled by the central processing and control system (32), separates products of the correct weight from those to be rejected.

  • Patent number: 6109000
    Abstract: A covering band (12) is pre-heated and then definitively heated in two subsequent areas (P,Z), and is subjected to primary pulling, in an area (T), where the covering band is pulled and applied to a blister band (1), and to secondary pulling in an area (R) which coincides with the pre-heating area (P). The speed of the covering band (12) is lower in the secondary pulling area (R), so as to determine a lengthening which corresponds at least to its maximum lengthening resulting from pre-heating. Cyclical detecting of reference marks (20) printed on the covering band determines temporary reducing of the covering band (12) speed in the secondary pulling point (R), so as to provoke an additional lengthening. The device includes pulling means (5,11) of the blister band (1) and covering band (12), pre-heating means (11) and heating means (13) for the covering band (12), detecting means (16), and driving means (30) acting with different speeds, controlled by the detecting means (16).

  • Patent number: 6070385
    Abstract: A device for transferring blister packs comprises an intermediate station situated between a working station (3) and a packaging line. The intermediate station includes a clamp for receiving and holding at least one blister pack. First and second groups of suction cups are driven by a two-arm mechanism situated in the intermediate station. In a first position, the first group of suction cups is placed in the working station for picking up one blister pack while the second group of suction cups is over the intermediate station for picking up another blister pack temporarily held by the clamp. In a second position, the first group of suction cups is located over the intermediate station, to release the blister pack previously picked up, that is received and held by the clamp, while the second group of suction cups is over the packaging line to deliver the blister pack previously picked up.

  • Patent number: 6050059
    Abstract: The packaging apparatus for bags containing products for infusion envisages a plurality of stations located one after another along a feed line and used first to continuously cut successive individual pieces of fabric from a continuous strip of fabric, then to transform the piece of fabric from its flat configuration to a bag configuration, tubular in shape and with an open top which forms the mouth and into which a dose of product is inserted; the tubular bag is then moved to stations which cut the excess part of the mouth to size and close the mouth by tying it with a continuous thread, so as to form a closed bag, containing a single dose of product and having a projecting upper portion of thread; finally, a label is attached to the thread on each bag and the label is inserted in the bag tying zone.

  • Patent number: 5802820
    Abstract: Between a machine that manufactures bags of variable volume containing cohesionless material (exemplified by tea bags), and a packing machine which packs the bags as stacks, an indexing rotor with pockets in its outer periphery acts, in cooperation with a loading mechanism and an unloading mechanism at respective angularly distributed stations, at which each bag is respectively oriented bottom down and bottom up, to tend to redistribute the cohesionless material away from each bag bottom and to cause individual bags to be generally equally thick relative to one another.

  • Patent number: 5630347
    Abstract: The device includes dispensing units, each of which features a pair of counter-rotating rollers, between which there is inserted the end of a blister band unrolling from a reel and pushed toward a delivery opening. A blade moves vertically and cooperates with the edge of a support surface, situated downstream of the two rollers, to cut the blister band after a predetermined number of products, counted by a sensor, have passed through the delivery opening. An electric motor drives two ratchet coupling mechanisms acting in opposite directions and connected, by belts or chains, with pulleys or toothed wheels which are integral respectively with the rollers and with a pinion meshing with a rack fastened to the blade. An electronic unit controls and checks the working of the device. Optionally, a token, or coin receiver, a banknote reader or other payment mechanism may be used to allow the user to activate the dispenser after making a payment.

  • Patent number: 5626171
    Abstract: The mechanism (27, 28) which regulates the volume of the distributors (16, 116) is connected to a shaft (41) coaxial to the shaft of the distributor carrousel. When the motor (63) is at standstill, the two coaxial shafts (2,41) rotate in the same direction and at the same speed. Whenever the motor (63) is activated in one direction or the other with the carrousel at the standstill or rotating, the inner shaft (41) rotates relative to the outer shaft (2), in the direction and to the extent necessary for the required regulation of volume of the distributors. The volume of the distributors is controlled remotely by a programmable processor (77).

  • Patent number: 5588643
    Abstract: Tubular blanks, from which containers to be filled and closed are set up, are stacked in flat condition inside a magazine (3), so that they rest on supporting bars. A back edge of the lowermost blank of the stack is engaged by a pair of lugs mounted on a belt conveyor situated under the magazine, so that the lugs protrude upwards beyond a rest plane defined by the supporting bars. The lowermost blank is stripped by passing it through a passage delimited by the supporting bars and stops situated above the supporting bars, and aimed at stopping blanks of the stack situated above the blank just withdrawn. The belt conveyor carries the withdrawn blank through following working stations.

  • Patent number: 5581975
    Abstract: All the carousels of the machine are provided with grippers for holding the flasks. A carousel with grippers (6) for holding the flask by the neck is followed by a carousel with grippers (7) for holding the flask by the body and so on. Between the jaws of each gripper there is provided in the middle region a vertical opposition element (35) fixed onto a horizontal slide (36) supported by the gripper body (33) and connected to a mechanism which modify the position of the said opposition element according to the diameter of the flasks. The opposition element is directed towards the flask with a concave-profile front face. The orbits (29, 30) along which the grippers of two consecutive carousels travel intersect each other in the zone where the flasks pass from one carousel to the other. In this zone the flask is immediately held between the opposition elements of the opposite grippers of the carousels, which open and close alternately.
