Apparatus for manufacturing and unloading plastic container preforms
The patent US12042969B2 describes an advanced apparatus designed for the manufacture and unloading of preforms used in the production of plastic containers. The apparatus integrates an injection molding device for creating multiple preforms and a cooling and extraction system that includes a grip assembly with cooling receptacles. This system features first transferring means to move warm preforms from the molding device to the grip assembly, and an unloading plate that supports grip bodies arranged in a matrix. These grip bodies can be selectively engaged to extract cooled preforms and unload them onto a designated surface. Additionally, the apparatus includes a selective extraction device that organizes the transfer of a predetermined subset of preforms to a control and inspection device, ensuring an orderly process.
The control and inspection device is equipped with various units for thorough examination of the preforms, including video cameras for inspecting seals, body defects, and color, as well as units for measuring thickness and temperature. The apparatus also allows for the movement of the preforms during inspection, enabling detailed analysis of their properties. Conveyance options include belt or chain conveyors, air jet conveyors, and rotating rollers, with provisions for accumulation and timing systems downstream. The design emphasizes efficiency and precision in the manufacturing process, with isolated access areas for the control and inspection device to maintain operational integrity. Overall, this patent outlines a comprehensive solution for enhancing the production and quality control of plastic container preforms.
