Problems solved by technology

[0033] Thus, depending on the thermoplastic material used and the type of finished container desired, the forceful insertion of the gripper jaws around the neck can sometimes generate material debris that constitutes undesired contamination, inter alia affecting the manufacturing process or damaging the container, e.g. Cannot be used because it is too fragile or unattractive

Embodiment Construction

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

[0083] In a known manner, the preform 14 is made of thermoplastic material, especially PET (polyethylene terephthalate), intended to be heated and then molded by blowing or with stretch-blowing to finally obtain a container 12, such as a vial or bottle.

[0084] The preform 14 is generally produced according to an injection molding process, which may be integrated with the apparatus or carried out at another location than the apparatus 10 .

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

[0086] The preform 14 has a body 16 , here generally cylindrical, closed at its lower end by a base 18 and, opposite, open at its upper end by an opening 20 delimited by the lip of a neck 22 .

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

Abstract

A preform transfer device includes at least one clamp including two levers pivoting between an open position and a closed position and elements for the elastic return of the levers to the closed position. The device includes a mechanism for selectively controlling the opening and closing of the clamp, this mechanism including: a lever spreading member driven by a link including at least one free end able to interact with actuating elements to cause the clamp to open against the force of the elastic return elements, and associated locking elements that are able to move between a locked position in which the clamp is held in the open position and a retracted position in which the clamp is free to close, the locking elements being able to interact with second actuating elements designed to cause the locking element to move from the locked position to the retracted position, 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] A large number of devices are already known for the manufacture of containers for the manufacture 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 ...
