Abstract

A transfer unit for transferring glass articles from a supporting surface to a carry-off conveyor, the transfer unit includes a pickup member for engaging the articles for transfer and is hinged to one end of an actuating arm to rotate with respect to the actuating arm about a movable hinge axis under the control of a control unit for adjusting the position of the pickup member independently of the position of the actuating arm.

Claims

1. A transfer unit for transferring glass articles from a supporting surface to a carry-off conveyor, the transfer unit comprising:

a fixed support;

a pickup member for engaging the articles for transfer;

an actuating arm for activating said pickup member, said actuating arm being pivotably attached to the fixed support, said pickup member being positioned at a free end of the actuating arm hinged to said actuating arm to rotate with respect to the actuating arm about a movable hinge axis, the movable hinge axis being perpendicular to the supporting surface; and

a control unit provided to adjust the position of said pickup member about said movable hinge axis independently of the position of said actuating arm, and to control the actuating arm.

2. The unit as claimed in claim 1, wherein said control unit adjusts the position of said pickup member continuously with respect to said actuating arm.

3. The unit as claimed in claim 1, wherein said control unit comprises a dedicated electric motor.

4. The unit as claimed in claim 3, wherein said electric motor is located beneath said supporting surface.

5. The unit as claimed in claim 3, wherein said electric motor is carried by said actuating arm.

6. The unit as claimed in claim 4, wherein said control unit also comprises a transmission interposed between said pickup member and said electric motor.

7. The unit as claimed in claim 6, wherein said transmission is a gear transmission.

8. A transfer unit for transferring glass articles from a supporting surface to a carry-off conveyor, the transfer unit comprising:

a fixed support;

a pickup member for engaging the articles for transfer;

an actuating arm for activating said pickup member, said actuating arm being pivotably attached to the fixed support, said pickup member being hinged to said actuating arm to rotate with respect to the actuating arm about a movable hinge axis perpendicular to the supporting surface;

a control unit provided to adjust the position of said pickup member about said movable hinge axis independently of the position of said actuating arm,

wherein said actuating arm is an articulated arm comprising a first elongated portion hinged to said fixed support to rotate about a fixed hinge axis, and at least a second elongated portion connected to the first elongated portion to rotate about a further movable hinge axis, and to rotate with respect to the pickup member about said movable hinge axis; and

an electric actuating unit provided to rotate said first and second elongated portion with respect to each other and with respect to said fixed support.

9. The unit as claimed in claim 8, wherein said electric motor is activated independently of said electric actuating unit.

10. The unit as claimed in claim 8, wherein said electric actuating unit comprises a first and a second electric motor, and further control unit for controlling said first and said second electric motor independently of each other.

11. The unit as claimed in claim 10, wherein said first and said second electric motors are located beneath said supporting surface.

12. The unit as claimed in claim 11, wherein said first and said second electric motors are located adjacent to each other.

13. The unit as claimed in claim 8, wherein said electric actuating also comprises a first mechanical transmission activated by said first electric motor to rotate said first elongated portion about said fixed hinge axis, and a second mechanical transmission activated by said second electric motor to rotate the first and second elongated portions with respect to each other about said further movable hinge axis, at least one of said mechanical transmissions being located beneath said supporting surface.
