AI Technical Summary

Technical Problem

Existing precast component processing equipment is prone to being scrapped when the equipment is shut down due to excessive thermal stress on the precast components, resulting in low productivity and serious waste, as well as insufficient equipment reliability and cost competitiveness.

Method used

Design a preform processing equipment, including a supply line, a closed conveying loop, an unloading component, and an actuation control device, which can switch between an operating state and a recirculation state. By controlling the movement of the preform in the conveying loop and adjusting the temperature of the furnace, the equipment can avoid overheating of the preform and achieve rapid recovery.

Benefits of technology

It significantly improves productivity, reduces waste during equipment downtime, enhances equipment reliability and cost competitiveness, and adapts to the supply of prefabricated components of different diameters and shapes.

Abstract

An apparatus (1) for processing plastic preforms, comprising a line (10) for feeding preforms (50), the preforms comprising a preform body (51) and a preform mouth (52), the feeding line (10) being arranged upstream of a furnace (2) for conditioning the preforms (50), an assembly (20) being provided for unloading the preforms (50), the assembly is arranged downstream of a conditioning furnace (2) and is designed to feed the preforms (50) to a transfer carousel or a blow carousel, the conditioning furnace (2) being associated with a closed conveying circuit (3) comprising a plurality of support elements (4) configured to support the respective preforms (50), the feed line (10) having a feed device (11), the feed device (11) being arranged downstream of the conditioning furnace (2) and being designed to feed the preforms (50) to the transfer carousel or the blow carousel. The supply device is designed to supply the preforms (50) to the closed conveying circuit (3), and the unloading assembly (20) has an unloading device (21) designed to remove the preforms (50) from the closed conveying circuit (3), characterized in that the apparatus comprises a control and actuation device, the control and actuation device is configured to actuate a transition of the apparatus (1) between an operating state in which the preforms (50) are fed to the closed conveying circuit (3) via the feed line (10) and sent to the transfer carousel or the blow carousel via the unloading assembly (20), and a recirculation state in which the preforms (50) are fed to the closed conveying circuit (3) via the feed line (10) and sent to the transfer carousel or the blow carousel via the unloading assembly (20). The supply of the preforms (50) to the closed conveying circuit (30) via the supply line (10) is interrupted, and wherein the unloading assembly (20) is functionally unconnected to the closed conveying circuit (30), in a recirculation state, the preforms (50) supported by the respective support elements (4) are moved along the closed conveying circuit (3), and the preforms (50) which are supported by the respective support elements (4) and which are not removed by the unloading assembly (20) are sent again towards the conditioning furnace (2).
