Problems solved by technology

However, this solution is unsatisfactory, since the centrifuge bowl volumetric size would then be very large and, moreover, the travel time of the preforms increases so that the first preforms are discharged at the same time as they reach the centrifuge bowl The start-up of production equipment is delayed between the time of export

Embodiment Construction

[0050] In the following description, components having the same structure or similar functions will be denoted by the same reference numerals.

[0051] In the following description, without limitation, the following local orientations are taken for each preform present in the centrifuge bowl of the apparatus:

[0052] - a radial direction R, which is oriented from the inside to the outside from the axis of rotation of the turntable;

[0053] - a tangential direction T, which is orthogonal to the radial direction R, extending in the plane of the turntable, oriented from upstream to downstream in the direction of rotation of the turntable;

[0054] - Vertical direction V, which is oriented from bottom to top in the direction opposite to gravity.

[0055] figure 1 shows a device 10 for arranging and erecting preforms 12 for forming containers of thermoplastic material by molding of preforms, in particular blow molding or stretch blow molding components of the device (not shown)....

Abstract

The invention relates to a device (10) for aligning preforms (12) in a row and righting same, the device (10) comprising a bowl centrifuge (20) including: a horizontal circular platen (24) rotating about a vertical axis (B); a fixed peripheral rail (28) including at least one receiving portion (28A) that is intended to retain the body (14) of the preforms (12) on the rotating platen (24) and inside the bowl (20); and a preform chute (30) which discharges the preforms (12) in bulk onto the rotating platen (24) towards the receiving portion (28A) of the rail (28). The device is characterised inthat the bowl (20) comprises at least one damper (35) for reducing the rebound effect of the preforms (12) against the receiving portion (28A) of the rail (28).

Description

technical field [0001] The invention relates to a device for aligning and erecting preforms, said device having a centrifugal drum with: [0002] - a circular horizontal turntable that can rotate around a vertical axis; [0003] - Peripheral fixed guardrails; [0004] - a first alignment angular sector of the centrifuge bowl comprising at least one receiving portion for retaining the body of the preform on the turntable within the centrifuge bowl; [0005] - a feeder for the preforms, which discharges the preforms randomly onto the turntable in the direction of the receiving part of the guardrail; [0006] - A second vertical angular sector of the centrifuge bowl, the second vertical angular sector having vertical elements for erecting the preforms. Background technique [0007] The device is intended for use in production plants for the production of containers of thermoplastic material, in particular containers of polyethylene terephthalate (PET), by preform forming, in...
