Abstract

A device for orienting objects in which a main axis (S) can be identified and comprising: first rotation means (11, 12), configured to bring about the rotation of an object (P) around a first axis (X); second rotation means (21), configured to bring about the rotation of an object (P) around a second axis (Y) perpendicular to the first axis (X); an optical detection device (31, 32), configured to capture images and/or a video of the object (P) during the rotation around the first axis (X); control means (50), configured to control the actuation of the first rotation means (11, 12) and of the second rotation means (21) and to receive and process the images and/or videos captured by the optical detection device (31, 32); said control means (50) being further configured to: recognize, during the rotation of the object (P) around the first axis (X), a first position in which a main axis (S) of the object (P) lies in a given plane of orientation (A); recognize, during the rotation of the object (P) around the first axis (X), a second position in which the object (P) assumes a pre-established angular position relative to the first rotation axis (X).

Claims

1. A device for orienting objects in which a main axis (S) can be identified, characterized in that it comprises:

rotation means (11, 12, 21, 41, 42, 43), configured to bring about the rotation of an object (P) around a first axis (X);

an optical detection device (31, 32), configured to capture images and/or a video of the object (P) during the rotation around the first axis (X);

control means (50), configured to control the actuation of the rotation means (11, 12, 21, 41, 42, 43) and to receive and process the images and/or videos captured by the optical detection device (31,32);

said control means (50) being further configured to;

recognize, during the rotation of the object (P) around the first axis (X), a first position in which a main axis (S) of the object (P) lies in a given plane of orientation (A).

2. The device according to claim 1, wherein said control means (50) are configured to recognize, during the rotation of the object (P) around the first rotation axis (X), a second position in which the object (P) assumes a pre-established angular position relative to the first rotation axis (X).

3. The device according to claim 1, wherein the optical detection device (31, 32) comprises a profile detector (31, 32), the control means (50) being configured to recognize at least one area of the surface of the object (P) in which the profile exhibits a given conformation.

4. The device according to claim 3, wherein the profile detector (31, 32) is positioned in such a way as to detect a profile of the object (P) lying in the plane of orientation (A).

5. The device according to claim 4, wherein:

the control means (50) are configured to receive, in real time, during the rotation of the object (P) around the first axis (X), the images of the profile of the object (P) in the plane of orientation (A);

the control means are provided with a recognition algorithm by means of which they are capable of detecting the change in the profile of the object (P) in the plane of orientation (A) during the rotation of the object (P) around the first axis (X);

by means of said recognition algorithm the control means (50) are further capable of recognizing when a pre-established area of the surface of the object (P), whose profile is illuminated by the light source (31), comes to lie in the plane of orientation (A) during the rotation of the object (P) around the first axis (X).

6. The device according to claim 1, wherein the optical detection device (31, 32) comprises a video capture device (32), the control means (50) being configured to recognize at least a given area of the surface of the object (P) having pre-established characteristics.

7. The device according to claim 6, wherein:

the control means (50) are configured to receive, in real time, during the rotation of the object (P) around the first axis (X), the images of the surface of the object (P) picked up by the video capture device (32);

the control means (50) are provided with a recognition algorithm by means of which they are capable of recognizing the presence and position of a particular area of the surface of the object (P).

8. The device according to claim 1, comprising first rotation means (11, 12) structured so as to support an object (P).

9. The device according to claim 1, wherein the first rotation means (11, 12) comprise at least a roller (11) that can be driven in rotation around an axis parallel to the first axis (X).

10. The device according to claim 9, wherein the first rotation means (11, 12) comprise a second roller (12) that can be driven in rotation around an axis parallel to the first axis (X).

11. The device according to claim 1, comprising second rotation means (21) provided with a support (21) that can be driven in rotation around the second axis (Y).

12. The device according to claim 1, wherein the first and the second rotation means are mobile relative to each other, along the second axis (Y), between a first position, in which the second rotation means (21) are in a lowered position, below the first rotation means (11, 12), and the object (P) is supported by the first rotation means (11, 12), and a second position, in which the second rotation means (21) are in a raised position, above the first rotation means (11, 12), and support an object (P) above the first rotation means (11, 12).

13. The device according to claim 1, comprising:

a fixed cradle (41), structured so as to contain the movements of the object (P) in the plane of orientation (A), said fixed cradle (41) being open at the top and having a concave surface (41c) intended to delimit, at least laterally, a housing for an object (P);

a first (42) and a second roller (43), which are concentric relative to the first axis (X) and project from the bottom of the fixed cradle (41) and are motorized independently of each other.

14. A method for orienting an object, comprising the following steps:

bringing about the rotation of an object (P) around a first axis (X);

capturing images and/or a video of the object (P) during the rotation around the first axis (X);

recognizing, during the rotation of the object (P) around the first axis (X), a first position wherein a main axis (S) of the object (P) lies in a given plane of orientation (A);

stopping the object (P) in the first position;

bringing about the rotation of the object (P) around a second rotation axis (Y) perpendicular to the plane of orientation (A) in such a way as to orient the main axis (S) parallel to the first rotation axis (X) in the plane of orientation (A);
