ABSTRACT:

In a bottle extractor, the different points of the surface of the rods that join head and handling fingers of the bottles, are exposed to the contaminating atmosphere with very different intensity, giving rise to problems in the operation.
The applicant has developed a bottle extractor, which maintains the same length of rod on the outside, under any circumstances, so the deterioration of the surface is even. Therefore, the head has been split into two parts, the head (itself) and head base. The head base remains in fixed position and the head moves as required by the user with respect to the head base, making a fixed amount of rod length stand out from the head during the work. All of this will be understood better with the drawings enclosed.
The bottle extractor for hollow glass moulding machines, of this invention, is of the type comprised of bottle handler fingers, a head joined to a fixed position spin axis and which includes at least one fluidic action cylinder, whose rod is joined to the fingers. It is characterised because the head is comprised of a mobile head supporting at least one fluidic action cylinder, a head base joined to the fixed position spin axis and means to move the mobile head with respect to the head base.
It is also characterised because the means to move the mobile head with respect to the head base are nut-screw elements, one of the elements being placed in the mobile head and the other in the head base.
It is also characterised because the mobile head is comprised of some flaps, which envelop the head base.
It is also characterised because it has a slip bushing, which channels the air from the shaft to the mobile head.
