Abstract

The invention relates to an apparatus for aligning box-shaped articles of various sizes on a conveyor belt, as well as a printing station, a reading station, and a labelling station including said apparatus. The apparatus comprises an input conveyor belt operable to move transversally with respect to an output conveyor belt conveying direction, to adapt to a transverse size of a transported box-shaped article, and feed said output conveyor belt with corresponding aligned article.

First claim

The invention claimed is:

1. An apparatus for aligning box-shaped articles of various sizes in a conveying direction on a conveyor belt, comprising:
an output conveyor having output conveyor drive means and an output conveyor belt operable to transport said box-shaped articles in the conveying direction, with a guide member fastened to the output conveyor and allowing a face of a box-shaped article transported on the output conveyor belt to slide along it in the conveying direction, the guide member having a guiding portion extending beyond an entrance extremity of the output conveyor belt;
an input conveyor having input conveyor drive means and an input conveyor belt, coplanar with the output conveyor belt, operable to transport the article in said conveying direction with said face of the transported article sliding along the guiding portion of the guide member, and deliver the article to the entrance of the output conveyor belt, the input conveyor including an input guide member disposed on a side of the input conveyor belt opposite to the guiding portion and facing the guiding portion, and fastened to the input conveyor, the input guide member allowing an opposite face of the box-shaped article transported on the input conveyor belt to slide along it in the conveying direction,
wherein the input conveyor has further drive means operable to move the input conveyor belt in translation in a direction perpendicular to the conveying direction and make the input guide member to push the transported article against the guiding portion.

2. The apparatus according to claim 1 , wherein
the guiding portion of the guide member is elevated above a conveying plane defined by the output conveyor belt; and
the further drive means is operable to make a part of the input conveyor belt to pass underneath the guiding portion.

3. The apparatus according to claim 1 , wherein an input guide member extension is fastened to the input guide member, aligned with the input guide member, extending above the conveying plane of the output conveyor belt and facing the guide member, said input guide member extension being operable to slidingly guide a box-shaped article transferred from the input conveyor belt to the output conveyor belt by maintaining it in contact with the guide member.

4. The apparatus according to claim 1 , further comprising a top guiding member disposed above a portion of the output conveyor belt and top drive means operable to make the top guide member to move in translation in a direction perpendicular to said portion of the output conveyor belt, and make the top guiding member to press on a top face of the box-shaped article transported on said portion of the output conveyor belt.

5. The apparatus according to claim 4 , wherein the top guiding member is disposed at the level of the entrance extremity of the output conveyor belt and further extends above a portion of the input conveyor belt.

6. The apparatus according to claim 4 , wherein the top guiding member is a top conveyor belt.

7. A printing station for printing on box-shaped articles of various sizes, comprising:
the apparatus for aligning box-shaped articles of various sizes in a conveying direction on a conveyor belt according to claim 1 ;
a print head of a printer operable to print on a face of a box-shaped article aligned by said apparatus on the input conveyor belt, the print head being mounted on a support being one of the guiding portion of the guide member, for printing on a first side face of the box-shaped article abutting said guiding portion, and the input guide member, for printing on a second side face of the box-shaped article opposite to the first side face and abutting said input guide member; and
a control unit having a processing unit and being connected to the printer, the input conveyor and the output conveyor, operable to control the printer and motion of the input conveyor belt and the output conveyor belt to print data on the face of the box-shaped article abutting the support.

8. A printing station for printing on box-shaped articles of various sizes, comprising:
the apparatus for aligning box-shaped articles of various sizes in a conveying direction on a conveyor belt according to claim 4 ;
a print head of a printer operable to print on a face of a box-shaped article aligned by said apparatus on the output conveyor belt, the print head being mounted on a support being one of the guide member, for printing on a side face of the box-shaped article transported on the output conveyor belt abutting said guide member, and the top guiding member, for printing on a top face of the box-shaped article transported on the output conveyor belt abutting said top guiding member; and
a control unit having a processing unit and being connected to the printer, the input conveyor, the output conveyor, and the top drive means, operable to control the printer and motion of the input conveyor belt, the output conveyor belt and the top guiding member to print data on the face of the box-shaped article abutting the support.

9. A reading station for reading data on box-shaped articles of various sizes, comprising:
the apparatus for aligning box-shaped articles of various sizes in a conveying direction on a conveyor belt, according to claim 1 ;
a reader operable to read data on a face of a box-shaped article aligned by said apparatus on the input conveyor belt, the reader being mounted on a support being one of the guiding portion of the guide member, for reading data on a first side face of the box-shaped article abutting said guiding portion, and the input guide member, for reading data on a second side face of the box-shaped article opposite to the first side face and abutting said input guide member; and
a control unit having a processing unit and being connected to the reader, the input conveyor and the output conveyor, operable to control the reader and motion of the input conveyor belt and the output conveyor belt to read data on the face of the box-shaped article abutting the support.

10. A reading station for reading data on box-shaped articles of various sizes, comprising:
the apparatus for aligning box-shaped articles of various sizes in a conveying direction on a conveyor belt according to claim 4 ;
a reader operable to read data on a face of a box-shaped article aligned by said apparatus on the output conveyor belt, the reader being mounted on a support being one of the guide member, for reading data on a side face of the box-shaped article transported on the output conveyor belt abutting said guide member, and the top guiding member, for reading data on a top face of the box-shaped article transported on the output conveyor belt abutting said top guiding member; and
a control unit having a processing unit and being connected to the reader, the input conveyor, the output conveyor, and the top drive means, operable to control the reader and motion of the input conveyor belt, the output conveyor belt and the top guiding member to read data on the face of the box-shaped article abutting the support.

11. A labelling station for applying labels on box-shaped articles of various sizes, comprising:
the apparatus for aligning box-shaped articles of various sizes in a conveying direction on a conveyor belt, according to claim 1 ;
a labelling unit operable to apply a label on a face of a box-shaped article aligned by said apparatus on the input conveyor belt, the labelling unit being fastened to a support being one of the guiding portion of the guide member, for applying the label on a first side face of the box-shaped article abutting said guiding portion, and the input guide member, for applying the label on a second side face
