A device for transferring objects, in particular containers such as preforms or bottles, comprising a support () which is rotated about an substantially vertical rotational axis and which supports at least one transfer arm () with an inner radial part fixed to the support () and an outer radial part () adapted for sliding with respect to said inner radial part along an elongation axis held within a plane substantially perpendicular to the rotational axis of said support (), the outer radial part () having a gripper head () adapted for supporting at least one object, wherein said head () is adapted for sliding, with respect to the inner radial part, along an elongation axis substantially parallel to the rotational axis of the support ().

Object transferring device with a transfer arm having a substantially vertically movable gripper head

A molding device for manufacturing thermoplastic containers by blow-molding or stretch-blow-molding heated parisons. The molding device having a blow-molding mold of the hinged mold type with at least two mold halves which can be separated from one another by rotation about a common axle of articulation under the action of an actuating device. The actuating device is designed in such a way that the two mold halves have respective angles of opening on each side of the parting plane of the mold which are not equal.

Rotary device for transferring containers, with a base () rotating about an axis () and supporting a mobile assembly () comprising: a main arm () pivoting () on the base, a gripping pincer () at the free end of the main arm, and a rotary roller () which is solidly connected to the main arm and interacts with a fixed curvilinear cam () with a closed contour; the pivot shaft () and the free end of the main arm define a line (L) which extends approximately tangentially to the circular trajectory of the pivot axis, which precedes the free end of the arm in the direction (F) of rotation of the base; the cam is such that, when the base rotates, the end of the main arm is moved approximately radially; and the gripping pincer mounted on the free end of the main arm follows a predetermined circular path, having inverse convexity with respect to the trajectory of the rotary base, within a fixed angular range (&#x3b1;) of rotation of the base.

Rotary device for transferring containers

Device for conveying objects, includes a rotating support having a transfer arm which consists of a plate and a gripper head which can bear at least one object and which is slidingly mounted in relation to the plate according to a direction. The gripper head () is coupled to a slider sliding in a slide rail fixed to the plate, and including a first and second cam system in order to respectively slidingly drive the gripper head and to pivotingly drive the plate, according to the angular position of the arm around the axis of rotation of the support. The slider is constructed as a single part which has an overall rail shape, and the profile of the slider is complementary with respect to the profile of the slide rail. The gripper head is fixed such that it overhangs on the distal end section of the slider.

Conveyor device with an improved transfer arm

A rotary machine for producing recipients made of a thermoplastic material by drawing and blowing performs by a molding device which is provided with an openable mold and a movable drawing rod, a device for supporting and driving the drawing rod, which is embodied in such a way that it is mechanical and includes a power take-off device for generating, on the basis of a monodirectional rotary rotation, two rotary motions of given angular amplitudes of a rocker in two predetermined angular places of a merry-go-round path and a device for converting the two rotary movements of the rocker into two opposite linear alternately descending and ascending displacements of a drive unit connected to the drawing rod.

Stretch-blow molding machine with mechanically controlled stretch rod

A blow-molding installation for manufacturing receptacles from blanks of thermoplastic polymer, said installation comprising a bell-nozzle for blowing a fluid under pressure into a blank () disposed in a cavity () of a mold (), the end of the nozzle being in the shape of a bell () which is suitable, during blow-molding, for being pressed into leaktight end-to-end abutment against a wall (F) of the mold while capping the neck () of the blank that emerges from said wall; said installation further comprises means () for securing the nozzle to the wall of the mold by mutual attraction, which means can be activated, after the nozzle has been brought into end-to-end contact with the wall (F) of the mold without flattening a sealing gasket (), so as to attract the nozzle () and the wall (F) towards each other with an attraction force greater than the repulsion force due to the pressure of the blow-molding fluid.
