Detailed Description

Reference is made to the accompanying drawings. The automatic positioning device for the film covering comprises a film pulling mechanism 100 and an alignment sensor 200, wherein the film pulling mechanism is arranged behind a film sealing device 300, and the film sealing device 300 is used for bonding a film on a cup to seal the cup 400. In the filling line, the cups 400 are arranged in an array and transported along the line. The film 500 for sealing the cup mouth is in a roll 501, is rolled out by a drawing film to cover the cup 400, is adhered to the cup by the film sealing device 300, the film 500 is provided with label patterns corresponding to the cup 400 one by one,

as shown, the film drawing mechanism 100 is disposed at a position adjacent to the rear of the film sealing device 300, and no other device for processing the filled and sealed cup is disposed between the film drawing mechanism and the film sealing device.

The film drawing mechanism comprises a film pressing roller 11 and a film drawing roller 12, and a film guide roller 13 is arranged on the front side of the film drawing mechanism. The film supporting frame 14 is arranged at the rear side of the film drawing mechanism, so that a film head of a drawn film can be prevented from being involved in the film drawing mechanism.

Film pressing roller 11 and draw membrane cylinder 12 setting to be in the top of the conveying orbit of cup 400, film pressing roller 11 is last, draw membrane cylinder 12 under, the setting height of support film frame 14 is less than film pressing roller 11 and draws the clearance between membrane cylinder 12. The film pressing roller 11 is connected with a lifting driving cylinder 15, and the film pressing roller 11 is a driven roller capable of lifting; the film drawing roller 12 is connected with a driving motor 16. The film pressing roller 11, the film pulling roller 12, the driving motor 16 and the film supporting frame 14 are arranged on the mounting frame 10 of the film pulling mechanism.

The film guide roller 13 is arranged on the cantilever 17 connected with the mounting frame 10, the setting height of the film guide roller 13 is close to the film covering height of the cup 400, and after the film is sealed by the cup 400, the cup 400 is not influenced to be conveyed to the next station.

The index sensor 200 is connected to a controller of the film drawing mechanism, for example, to a controller of the driving motor 16 and a controller of the lifting driving cylinder 15, and the controller of the driving motor 16 and the controller of the lifting driving cylinder 15 may be the same controller. When the index sensor 200 senses and sends a signal, the controller controls the lifting driving cylinder 15 to lift the film pressing roller 11 according to the signal, and the driving motor 16 stops driving the film pulling roller 12. At this time, the label patterns of the film 500 at the film sealing device 300 are exactly aligned with the cups one by one, and after the sealing is bonded, the film 500 is gradually unwound as the cups 400 are fed forward, and the patterns on the film are aligned with the cups one by one at the film sealing device 300. As the cup begins to be conveyed forward, the film head in the film drawing mechanism 100 is also drawn back and conveyed forward following the cup.
