- As is known, many pourable food product comprising not only food product like milk, fruit juice or beverages in general, but also detergents are sold in articles having different shape and dimension.
- These articles are typically made within bottling units, which comprise a plurality of stations for carrying out respective operations on the articles.
- Very briefly, the bottling unit comprises at least one rinsing station for rinsing the articles, one filling unit for filling the articles with a pourable food product, one capping station for applying a plurality of caps onto the respective articles and one labelling station for applying labels onto the outer surface of respective articles.
- Though excellently performing, the known bottling units leave room for improvement.
- In particular, the outer surface of the articles can get wet or dirty inside the filling unit, thus affecting the proper operation of the labelling unit.
- Furthermore, the caps could not be precisely applied on the container, as regards to the position and the orientation of the caps, could be wet or even could have not been applied by the capping unit.
- In all these situations, the labelling unit of the known bottling unit uselessly applies the labels onto defected containers.

Control unit 19 receives the images ofarticle 2 extracted byinspection device 17 and generates, on the basis of the extracted images, a control signal fordischarge device 18 arranged along portion T4 of path T. - In particular, control signal is such that:
- in
case article 2 is suitable to be labelled insidelabelling station 14,discharge device 18 does not interfere with the advancement ofarticle 2 along portion T4; and - in
case article 2 is not suitable to be labelled insidelabelling station 14,discharge device 18discharges article 2 travelling along portion T4 by means ofchute 24. - As
article 2 is conveyed by star-wheel 34 along portion T4 of path T,: - at first,
body 3 ofarticle 2 is dried bydryer 38; - then
article 2 not suitable to be labelled insidelabelling station 14 are discharged from star-wheel 34 bydischarge device 18; and - finally,
body 3 of article is again dried bydryer 39. - In particular, the mouths of
nozzles relative dryers 36; 37; 38; 39 eject the air flow onto respective opposite lateral sides ofbody 3 ofarticles 2 travelling onto respective portions T2, T3, T4 of path T and conveyed by respective star-wheels - Furthermore, the mouths of
nozzles relative dryers 36; 37; 38; 39 are arranged at progressive increasing axial distances fromneck 4 and at progressive decreasing axial distances from bottom 5, asarticle 2 is advanced on respective portions T2, T3, T4 of path T by respective star-wheels Figure 14 ) - Accordingly,
article 2 is repeatedly axially dried fromneck 4 to bottom 5 parallel to axis H, asarticles 2 advances on portions T2, T3, T4 of path T and is conveyed by respective star-wheels - Furthermore, as
article 2 is advanced along portion T2 of path T by star-wheel 32,body 3 is at first dried only bynozzles 52a carried bybody 67 ofbox 58 ofdryer 36, and then dried by bothnozzles body 68 ofbox 58 andbody 60 of dryer 36 (Figure 9 ) . - As
article 2 is advanced along portion T3 of path T by star-wheel 33,body 3 is at first dried by bothnozzles body 70b ofbox 58 andbody 60 ofdryer 36, and then dried only bynozzles 53a carried bybody 70a ofbox 58 of dryer 36 (Figure 11 ). - As
article 2 is advanced by star-wheel 34 along portion T4 of path T,body 3 is at first dried only bynozzles 54a carried byportion 72 ofbox 58 ofdryers 38; 39 and then dried by bothnozzles portion box 58 and box 60 (Figure 12 ). - Then,
article 2 is either discharged bydischarge device 18 by means ofchute 24 if not suitable to be labelled inlabelling station 14, or conveyed todryer 39. - Finally,
body 3 is dried only bynozzles boxes dryers 39. - In particular,
fan 40 ofdryer box 57, and, thenboxes relative nozzles -
Fans 40 are cooled bypassages 88. -
Fans 91 ofextraction unit 90 is effective in discharging the air from the top offrame 22 by means ofdischarges 92. -
Sensors respective boxes dryer 35 andrespective boxes dryers - Star-
wheel 34outputs articles 2 dried and suitable to labelled at station O, from which they are conveyed insidelabelling station 14. - From an analysis of the features of unit 1 and method made according to the present invention, the advantages it allows to obtain are apparent.
- In particular,
inspection device 17 inspectsarticles 2, as the latter are conveyed bytransfer station 16 along curved path T. - In this way, on one hand,
inspection device 17 ensures thatarticles 2 which are not suitable to be labelled inlabelling station 14, e.g. becauserespective bodies 3 are damaged or becausecaps 15 have not been properly positioned or rings 21 have been detached fromrelative frames 20, are not conveyed bylabelling station 14, thus optimizing the efficiency oflabelling station 14 and, therefore, of whole unit 1. - On the other hand, the inspection of
articles 2 does not require a further dedicated linear station distinct fromtransfer station 14, thus reducing the whole size of unit 1 and simplifying the layout thereof. - Furthermore, unit 1 comprises a
discharge device 18, which dischargearticles 2 which are not suitable to be labelled along path T. - In this way, the discharge of
articles 2 not suitable to be labelled does not require a further dedicated linear station distinct fromtransfer station 14, thus further reducing the whole size of unit 1 and further simplifying the layout thereof. -
Transfer station 16 comprises star-wheels articles 2 gripped onrespective necks 4 along respective portions T1, T2, T3, T4 of path T. - Therefore,
inspection device 17 inspectsarticles 2 as the latter are gripped onrespective necks 4 and conveyed by star-wheel 33, anddischarge device 18discharge articles 2 as the latter are gripped onrespective necks 4 and conveyed by star-wheel 34. - In this way, the inspection of
articles 2 and the discharge ofarticles 2 does not create a need for a morecomplex transfer station 16, thus containing the overall cost of unit 1. - Furthermore, unit 1 comprises a plurality of
dryers dry necks 4, caps 15 andbodies 3 ofarticles 2 travelling on this path T. - It is therefore ensured that
labelling station 14 is fed with driedarticles 2 and can therefore properly operate. - Finally, it is apparent that modifications and variants not departing from the scope of protection of the claims may be made to unit 1 and to the method.
- In particular,
nozzles articles 2 travelling along respective portions T1, T2, T3, T4 of path T. - In this case,
fans 40 would be replaced by corresponding pumps. - Furthermore, the number of drying
stations 13,inspection devices 17 andejection station 18 can be varied according to the needs, such as for example increasing production speeds.
