Example Embodiment

[0082] figure 1 A linear apparatus 10 for manufacturing containers 12 from preforms 14 is shown schematically.

[0083] In a known manner, the preform 14 is made of a thermoplastic material, in particular PET (polyethylene terephthalate), for being heated and then moulded by blowing or by stretch-blowing to finally obtain a container 12, such as a vial or bottle.

[0084] The preform 14 is typically made according to an injection molding process, which may be integrated with the apparatus or carried out in a different location than the apparatus 10 .

[0085] like Figure 1A As shown, the preform 14 is generally in the shape of a tube, here extending vertically along a vertical main axis A.

[0086] The preform 14 has a main body 16 , here generally cylindrical, closed at its lower end by a bottom 18 and, on the opposite, open at its upper end through an opening 20 defined by the rim of a neck 22 .

[0087] From the bottom 18 to the neck 22, the cylindrical inner wall 26 ...

Abstract

The invention relates to a preform transfer device (50) comprising at least one clamp (54) consisting of two levers (54a, 54b) pivoting between an open position and a closed position and comprising means for the elastic return of the levers to the closed position, said device being characterized in that it comprises a mechanism (80) for selectively controlling the opening and closing of the clamp, this mechanism (80) comprising: a lever spreading member (82) designed to be driven by a link (84), the driving link of the member comprising at least one free end (88) able to interact with actuating means designed to cause the clamp to open against the force of the elastic return means of the levers, and associated locking means (92) that are able to move between a locked position in which theclamp is held in the open position and a retracted position in which the clamp is free to close, the locking means (92) being able to interact with second actuating means designed to cause the locking means to move from the locked position to the retracted position, in such a way as automatically to trigger the closure of the clamp.

Description

technical field [0001] The invention relates to a conveying device, in particular a conveying device for preforms or containers, and a linear machine for container production having such a device. Background technique [0002] Many devices are already known for the production of containers for the production of containers such as vials or bottles, in particular from preforms of plastic material, for example PET (polyethylene terephthalate). [0003] In these plants, the preform is generally first heated while passing through a thermal conditioning or heat treatment unit having at least one furnace for heating the preform to a temperature close to its glass transition temperature. A determined temperature is then conveyed directly to a molding unit, also called a blowing unit, to be shaped by blowing or stretch-blowing. [0004] Such a device has at least one conveying device for conveying the preforms and / or containers between the different units, usually by means of their ...
