Method for efficient resin supply using cartridge replacement
The granted patent US12023826B2 outlines a method for efficiently supplying liquid resin through a dual-cartridge system. The process begins with discharging liquid resin from a first cartridge, which is pushed out using a rod. If the remaining amount in the first cartridge is less than the target supply amount, the method involves replacing it with a second cartridge that has already undergone a dripping-out process. This ensures a continuous supply of resin to the target. The method also includes measuring the remaining resin in the first cartridge before its supply and allows for the second cartridge to be prepared for use while the first is still in operation.
Additionally, the patent describes a resin molding apparatus that incorporates a molding die and a liquid resin discharging mechanism. This mechanism is controlled to manage the supply of resin from the cartridges effectively. The supply process is designed to ensure that the transition between cartridges is seamless, with specific locations for starting and stopping the resin flow based on the rod's position. The method also includes checks to confirm that the resin from the second cartridge can be supplied normally. Overall, this innovation aims to enhance the efficiency and reliability of resin supply in manufacturing processes, particularly in producing resin-molded products.
