AI Technical Summary

Technical Problem

The existing devices for transporting and gripping preforms in thermal conditioning units are inefficient in quickly changing spinner noses to accommodate different preform models, requiring manual disassembly and reassembly, which is time-consuming and labor-intensive, especially when dealing with multiple spinner noses.

Method used

A device with a frame, preform conveying system, and mandrels that include a bayonet socket and pin mechanism, along with angular pre-orientation, blocking, and locking/unlocking means, utilizing a cam follower and movable cam path to securely lock and unlock the spinner nose to the mandrel, allowing for rapid changeover and automation through a robotic arm.

Benefits of technology

This solution significantly reduces the time required to change spinner noses, from four hours to a fraction of the time, enhancing efficiency and enabling faster format changes and maintenance in thermal conditioning units.

Abstract

Disclosed is a device (85) for locking and / or unlocking at least one spinner nose, intended to be mounted on a thermal conditioning unit comprising at least: - a frame (23); - a preform conveying device that consists of a plurality of supports and circulates along the frame (23); - mandrels that are rotatably mounted on each support of the conveying device, each mandrel comprising at least one bayonet socket intended to receive a pin that is integral with the spinner nose, characterized in that the locking and / or unlocking device (85) comprises: - an angular pre-orientation means (88) for each mandrel; - a means for preventing each spinner nose (64) from rotating; and - a means for locking and / or unlocking (90) the bayonet securing the spinner nose to the mandrel.
