Device for transferring hollow bodies, equipped with a cleaning tool
The invention relates to a transfer device for a hollow article comprising a conveyor wheel, transfer arms mounted moveably on the conveyor wheel, and at least one static cam. The at least one static cam comprising at least one cam path that cooperates with cam followers carried by the transfer arms to control the position thereof. The wheel carries at least one cleaning tool for a related cam path, and the cleaning tool is mounted movably and pressed against the cam path with sufficient force to enable the automatic cleaning of the cam path as the conveyor wheel rotates.
1. A transfer device ( 10 ) for a hollow article comprising:

4. The device ( 10 ) as claimed in claim 1 , wherein the slide ( 38 ) is fastened removably in place of a transfer arm ( 18 ).
5. The device ( 10 ) as claimed in claim 1 , wherein the cleaning tool ( 36 ) is carried by an arm ( 18 ).
6. The device ( 10 ) as claimed in claim 5 , wherein the device ( 10 ) has several cleaning tools ( 36 A, 36 B, 36 C) carried by a single slide ( 38 ).
7. The device ( 10 ) as claimed in claim 1 , wherein each cleaning tool ( 36 A, 36 B, 36 C) is carried removably on the slide ( 38 ), thereby enabling the cleaning tool to be replaced as required.
8. The device ( 10 ) as claimed in claim 1 , wherein the cleaning tool ( 36 A, 36 B, 36 C) includes a scraper blade ( 43 ), notably a rubber blade or a steel blade or a ceramic blade.
9. The device ( 10 ) as claimed in claim 1 , wherein the cleaning tool ( 36 A, 36 B, 36 C) includes a sponge that can be soaked in a cleaning product.
10. The device ( 10 ) as claimed in claim 2 , wherein the slide ( 38 ) is mounted on a dedicated seat on the conveyor wheel ( 12 ) between two adjacent transfer arms ( 18 ).
11. The device ( 10 ) as claimed in claim 2 , wherein the slide ( 38 ) is fastened removably in place of a transfer arm ( 18 ).
12. The device ( 10 ) as claimed in claim 2 , wherein the cleaning tool ( 36 ) is carried by an arm ( 18 ).
13. The device ( 10 ) as claimed in claim 2 , wherein each cleaning tool ( 36 A, 36 B, 36 C) is carried removably on the slide ( 38 ), thereby enabling the cleaning tool to be replaced as required.
14. The device ( 10 ) as claimed in claim 3 , wherein each cleaning tool ( 36 A, 36 B, 36 C) is carried removably on the slide ( 38 ), thereby enabling the cleaning tool to be replaced as required.
15. The device ( 10 ) as claimed in claim 4 , wherein each cleaning tool ( 36 A, 36 B, 36 C) is carried removably on the slide ( 38 ), thereby enabling the cleaning tool to be replaced as required.
16. The device ( 10 ) as claimed in claim 5 , wherein each cleaning tool ( 36 A, 36 B, 36 C) is carried removably on the slide ( 38 ), thereby enabling the cleaning tool to be replaced as required.
17. The device ( 10 ) as claimed in claim 2 , wherein the cleaning tool ( 36 A, 36 B, 36 C) includes a scraper blade ( 43 ), notably a rubber blade or a steel blade or a ceramic blade.
18. The device ( 10 ) as claimed in claim 3 , wherein the cleaning tool ( 36 A, 36 B, 36 C) includes a scraper blade ( 43 ), notably a rubber blade or a steel blade or a ceramic blade.
