Device for Blowing Out Hollow Bodies Made of Plastics

A device for blowing out hollow bodies (1), such as plastic containers, in a conveyor assembly, wherein the hollow bodies (1) are open at one end (2) and are closed at the other end (3) and comprise at the open end (2) a head (4) with a collar (5), the conveyor assembly comprising a transport line (6) with feed rails (7, 8) being inclined in a transport direction (9), wherein the hollow bodies (1) are supported with the collar (5) and with the upwardly directed open end (2) on the feed rails (7, 8) and are arranged relative to one another in a row with an axial distance (10) and are conveyed along the transport line, and wherein a facility for blowing a gas stream into the hollow space (11) of the hollow bodies (1) is arranged in a partial area of the transport line (6), the device comprising:

• a rotatable rotor (13) above and at a distance from the feed rails (7, 8), the rotatable rotor having multiple nozzle heads (14) directed radially outwardly, each nozzle head (14) comprising a gas feed line (15) and a nozzle (16), all nozzles (16) being arranged in a common plane wherein the common plane is arranged approximately perpendicular to a supporting surfaces (12) of the feed rails (7, 8) and runs through an central axis (17) of the hollow bodies (1) and during conveying of the hollow bodies (1), the rotor (13) rotates in a conveying direction (12, 18), and wherein, in an area (19) between the rotor (13) and the feed rails (7, 8), at least one nozzle head (14) interacts with the head area (4) of a respective hollow body (1).
