The present invention relates to packaging articles into portions of blister band, commonly known as blister packs.

More precisely, the invention relates to a method for transferring blister packs from a cutting station to a blister pack conveying line, and to a corresponding device which carries out this method.

DESCRIPTION OF THE PRIOR ART

Automatic machines have been heretofore provided for forming blisters in a continuous band of thermoformable material, in a suitable working station, and for filling the obtained blisters with relative articles, e.g. pharmaceutical products such as tablets, pills or capsules.

In another working station, a suitable film, usually of aluminum, is applied to the blister band, so as to close the blisters. Subsequently, the so closed blister band is cut in a cutting station, so as to obtain blister packs.

Usually, downstream of the blister pack producing machine is a blister packs conveying line operated in phase relation with the cutting station and aimed at feeding a packaging machine.

The blister packs are usually transferred from the cutting station to the conveying line by a device, basically including an oscillating arm, which is equipped with means for picking up the blister packs and which supported by driving means which rotate it about an axis perpendicular to the moving direction of the conveying line.

The arm oscillates between a pick up position, in the region of the cutting station, in which the picking up means pick up one blister pack, and a releasing position, in the region of the conveying line, in which the picking up means release the blister pack (see e.g. EP-A-0 466 660).

In this field, there is the problem of transferring pairs of blister packs from the cutting station of the blister pack producing machine to a single conveying line, which feeds the packaging machine.

SUMMARY OF THE INVENTION

The object of the present invention is to propose a method, which allows to transfer pairs of blister packs, arranged side by side, from the cutting of station to only one conveying line, in particular in a packaging machine.

Another object of the present invention is to propose a method, which ensures high productivity, reliability and practicality also when working with different sizes of blister packs.

A further object of the present invention is to propose a particularly strong, versatile and functional device, which carries out the above mentioned method.

Still another object of the present invention is to propose a cheap device obtained by a simple technical solution, which optimizes the transfer of pairs of blister packs picked up from the cutting station to the receiving station.

The above mentioned objects are obtained, in accordance with the contents of the claims, by means of a device for transferring blister packs from a cutting station to a blister pack conveying line, the device including:

The device described above carries out a method for transferring blister packs from a cutting station to a blister packs conveying line including:

BRIEF DESCRIPTION OF THE DRAWINGS

The characteristic features of the invention will be pointed out in the following description of a preferred, but not unique embodiment, with reference to the enclosed drawings, in which:

BEST MODES OF CARRYING OUT THE INVENTION

With reference to the above described figures, reference numeral 1 indicates the proposed device, which allows to transfer pairs of blister packs 2 from a cutting station 3 of a blister pack producing machine to a conveying line 4 which takes the blister packs 2 and feeds them to e.g. a packaging machine 5.

The cutting station 3 defines a cutting surface α, which, in the described case, is inclined with respect to the horizontal plane, in which the blister packs 2 are cut.

Likewise, the conveying line 4 defines a corresponding receiving surface δ, substantially horizontal, on which the blister packs 2 are released.

The device 1 basically includes transfer means, respectively a first transfer means 11 and a second transfer means 12.

As shown in the figures, the transfer means 11,12 includes two arms equipped with picking up means, respectively first picking up means 13 and second picking up means 14, in the region of respective ends.

The picking up means include e.g. suction cups connected in known way to a vacuum source, which is not shown (Figure 4).

The length of the first transfer means or arm 11 is different from the length of the second transfer means or arm 12.

At their extremities opposite to the respective picking up means 13, 14, the first transfer means 11 and the second transfer means 12 are carried respectively by a first shaft 15 and a second shaft 16.

The first shaft 15 and the second shaft 16 are parallel to each other and crosswise to a moving direction Z of the conveying line 4 (Figure 3).

The first shaft 15 and the second shaft 16 have different lengths and their axes 15b, 16b are positioned at different height levels.

More precisely, as shown in Figures 3 and 4, the axes 15b, 16b of the shafts 15, 16 lie in a plane β, which is inclined with respect to the cutting plane α and with respect to the receiving plane δ by the same angle ω.

At their extremity opposite to the one carrying the picking up means 13, 14, the first shaft 15 and the second shaft 16 carry, keyed thereto, relative toothed wheels 15a, 16a, first and second respectively.

The toothed wheels 15a, 16a engage with a single toothed belt 17 operated by driving means 18 in known way (Figure 4). Tightening means 17a are provided, which act on the toothed belt 17.

The driving means 18 drive the first transfer means 11 and the second transfer means 12 into simultaneous oscillation between a pick up position W (Figure 3), in which the first picking up means 13 and the second picking up means 14 are located at the cutting station 3, so as to pick up a pair of blister packs 2, and a release position Y (Figure 4), in which the first picking up means 13 and the second picking up means 14 are located over the conveying line 4, so as to release the pair of blister packs 2 onto the conveying line 4. The blister packs 2 are released offset with respect to each other.

It results that, during the transition from the pick up position W to the release position Y, the unity vector of the bisector of the common rotation angle described by the first and second transfer means 11, 12 is orthogonal to the surface β.

It is to be pointed out that during the oscillation step, the second transfer means 12, situated behind the first transfer means 11, considering the view arrow F of Figure 2, does not interferes with the first transfer means 11, which is shorter than the second transfer means 12 and which is operated by the first shaft 15, situated at a higher level with respect to the second shaft 16.

The above mentioned situation is facilitated by the fact that the first transfer means 11 as well as the second transfer means 12 are substantially L-like arms, suitably shaped, and are fastened to the respective shafts 15, 16 with e.g. the shorter side.

As shown in Figure 2, the conveying line 4 includes conveyors, first 41 and second 42, including e.g. pairs of side by side belts, which cooperate with the corresponding transfer means, first 11 and second 12, and a third conveyor 43 located downstream of the first and second conveyors.

The conveyors 41, 42, arranged one beside the other with their active run in the same surface δ, are operated stepwise in the movement direction Z, according to a predetermined step.

In particular, the blister packs 2 of each pair of blister pack picked up from the cutting station are released on the first and second conveyors 41, 42, in such a that they are offset with respect to each other, by an offset value "f", considering the first and second conveyors 41, 42 movement direction Z.

The offset "f", together with the relative positioning of the blister packs 2 on the cutting surface α, determines the longitudinal extension of the transfer means 11, 12.

The conveyors first 41 and second 42, respectively, are equipped with a plurality of corresponding lugs, first 41a and second 42a, respectively. The lugs are removably fastened to the belts forming each conveyor, so that the mutual distance between the subsequent lugs can be adjusted to define seats, which receive blister packs 2 having different size and orientation, i.e. positioned with the longitudinal symmetry axis parallel or perpendicular, as in the present case, with respect to the conveyors 41, 42 common movement direction Z.

As seen in Figure 2, the blister packs 2 held within the seats are guided, at their ends, by side panels 33, which are distant from each other by a distance "d4".

The side panels 33 extend along the whole length of the first and second conveyors 41, 42.

It is to be pointed out that the transfer means 11, 12 are advantageously formed like a fork, so that the corresponding tines 11a 12a of each fork, substantially parallel to each other, are distant from each other by a distance "d1".

The distance "d1" is bigger than the crosswise dimension "d2" of the conveyors 41,42 (Figure 2).

The maximum transversal dimension of the transfer means 11, 12, i.e. the distance "d3" between the outer edges of each tine 11a, 12a, must be smaller than the distance "d4" between the side panels 33.

The conveyors 41, 42 feed alternately the blister packs 2 to the third conveyor 43, which is likewise a belt conveyor and lies substantially on a same plane including the receiving surface δ, on which the first and second conveyors 41, 42 lie.

The first, second and third belt conveyors 41, 42, 43 are operated synchronously.

Likewise, the conveyor 43 is equipped with lugs 43a, removably fastened to the belt, so that the mutual distance between subsequent lugs can be adjusted to define seats for blister packs 2.

The blister packs 2 are fed to the third conveyor 43 alternately by the first and second conveyor 41, 42 in a merging station 6 located at a connection point between the first and second conveyors 41,42 and the third conveyor 43.

The merging station 6 is equipped with pushing means, first 61 and second 62, respectively, which act symmetrically crosswise to the respective first and second conveyors 41, 42, in opposite directions.

The principles of the blister packs transfer method carried out by the described device are easily understandable and fully explained in the following, beginning from a configuration, in which the transfer means 11, 12 are located at the cutting station 3.

The cutting surface α of the cutting station 3 is preferably inclined with respect to the vertical plane by an angle ranging from 0° to 90°.

A pair of blister packs 2, are situated in the cutting station, arranged side by side and with the relative longitudinal symmetry axes e.g. orthogonal to the first and second conveyors 41, 42 movement direction Z.

The transfer means 11, 12, oscillate simultaneously about the axes 15b, 16b of the shafts 15, 16, in phase relation with the blister packs 2 cutting in the cutting station 3, and reach the pick up position W, in which the corresponding first and second picking up means 13, 14 locate in the cutting station 3 near the respective blister pack 2.

When the transfer means 11, 12 reach the pick up position W, the picking up means 13, 14 are connected to a vacuum source, so as to create vacuum condition in the area of contact with the blister packs 2 and thus to hold the respective blister packs 2 on the side opposite to the one having the blisters.

The transfer means 11, 12 oscillate clockwise (Figure 3), in phase relation with the connection to the vacuum source, until they reach the release position Y, in which the blister packs 2 contact the relative conveyors 41, 42.

When in the release position Y, the transfer means 11, 12 are situated substantially under the blister packs 2 receiving surface δ with the relative tines 11a, 11b extending along the corresponding conveyor 41, 42 internally with respect to the side panels 33 (Figure 4).

The different levels of the shafts 15, 16 and the extension of the forks 11, 12, allow the forks 11, 12 to release the blister packs 2 of the pair of blister packs previously picked up from the cutting station onto the conveyors 41, 42, maintaining the offset "f".

The picking up means 13, 14 are disconnected from the vacuum source in phase relation with the transfer means 11, 12 reaching the release position Y, so as to release the blister packs 2 onto the respective conveyors 41, 42, within the seat defined by the lugs 41a, 42a.

The blister packs 2 longitudinal symmetry axes are normal with respect to the conveyors 41, 42 movement direction Z and the blisters 2a are turned upwards (Figure 2).

During the passage from the pick up position W to the release position Y, the blister packs 2 rotate clockwise by 90° to 180°, according to the inclination angle of the cutting surface δ in the cutting station 3, thus making the blisters 2a of the blister packs 2 rotate from the position, in which they are turned downward and touch the cutting plane δ to a position, in which they are turned upwards and blister packs are situated on the conveyors 41, 42.

The conveyors 41, 42, in phase relation with the disconnection from the vacuum source, and consequently, with the release of the blister packs 2, perform a predetermined number of steps of their sequence, e.g. one, so as to shift the released blister packs 2 with respect to the fork arms of the transfer means 11, 12 situated below, thus avoiding putting one blister pack on another.

The transfer means 11, 12, in phase relation with the blister packs 2 shifting, rotate counterclockwise, so as to pass from the release position Y to the pick up position W, thus beginning a new cycle of transferring blister packs 2 from the cutting station 3 to conveyors 41, 42.

Due to the synchronous movement of the conveyors 41, 42, blister packs 2 are fed to the merging station 6 alternately by the first conveyor 41 and the second conveyor 42.

Therefore, the blister packs 2 are fed to the third conveyor 43 alternately by the first conveyor 41 and the second conveyor 42 by the synchronous action of the respective pushing means, first 61 and second 62, so as to define one single row of products at the inlet of the packaging machine 5.

The described method and device obtain the object of transferring pairs of blister packs 2 arranged one beside the other from a cutting station 3 of a blister pack producing machine to a relative blister packs 2 conveying line 4, so as to feed a packaging machine 5.

It is to be pointed out that the objects are obtained by a very strong and functional device, working at high speed.

In case the blister packs 2 size is to be changed, it is enough to adjust the distance between the lugs 41a, 42a, 43a of the corresponding conveyors 41, 42, 43, so as to adapt the dimensions of the seats to the new blister packs 2 dimension.

In case the blister packs 2 size change is considerable, beside the adjustment of the distance between the lugs 41a, 42a, 43a, it is possible to substitute the whole transfer means 11, 12.

Likewise, in case the longitudinal symmetry axis of the blister packs 2 is parallel to the conveyors 41, 42, 43 common movement direction Z, it is enough adjust the distance between the lugs 41a, 42a, 43a of the corresponding conveyors 41, 42, 43.

It is to be pointed out that the particular shape of the transfer means 11, 12 avoids their mutual interference during movement, as well as interference with conveyors 41, 42, 43.

The offset of blister packs 2 on the conveyors 41, 42, 43 by an offset value "f", together with the positioning thereof in the cutting station 3 determines the forks extension and shape.

In the described example, the cutting station 3 feeds two blister packs 2 arranged one beside the other at the same time.

In case the cutting station 3 can feed more than two blister packs 2, it is sufficient to add a corresponding number of transfer means equipped with picking up means, with the necessary associated conveyors, onto which the blister packs 2 are released.

For instance, if the cutting station 3 feeds three blister packs 2 arranged one beside another, there are needed three transfer means, three corresponding conveyors and two additional conveyors, onto which the blister packs, suitably offset according to the previously described principles, are transferred by analogous merging stations 6.

All what has been said about the merging station 6 - third conveyor 43 - packaging machine 5 assembly is valid also for the two additional conveyors.

It is evident that the offset value "f" of each conveyor 41, 42, 43 depends on the number of blister packs 2 arranged side by side in the cutting station 3, i.e. depends on the number of conveyors.

It is also to be pointed out that the above described device is composed of few simple elements, what reduces the production costs.

It is understood that what above has been described as a pure, not limitative example, therefore possible structure variants remain within the protective scope of the present technical solution, as described above and claimed below.
