Embodiment Construction

[0011] The present invention relates to an adaptive hot melt supply system that can automatically regulate the flow of solid hot melt material, such as adhesive pellets, from the supply system to the melting system for melting. Hot melt systems can adapt to changing conditions (e.g., air supply, volume of feed material in hopper, size of feed material, caking of material due to increased temperature or humidity, etc.) that increase or decrease solids The flow of hot melt material from the supply system to the melting system. In this way, the adaptive hot melt supply system can continuously optimize the time required to deliver the solid hot melt material to the melting system to ensure that the solid hot melt material has sufficient residence time in the melting system to allow the solid material to be dispensed before melt. Prior art methods require the operator to periodically monitor the delivery of the solid hot melt material and to optimize the flow of the solid hot mate...

Abstract

The invention discloses an adaptive hot melt feed system. The adaptive hot melt feed system includes a melt system, a feed system, a gas control device, a sensor, and a controller. The melt system includes a heated vessel. The feed system is configured to deliver a solid material to the vessel of the melt system for melting. The gas control device is configured to control a supply of gas providedto the feed system to drive the solid material from the feed system to the melt system. The sensor can be configured to detect an amount of material in the vessel of the melt system. The controller isin electronic communication with the gas control device and is programmed to signal the gas control device to vary the supply of gas to the feed system based on a fill metric determined by the controller.

[0001] Cross References to Related Applications [0002] This application is based on U.S. Provisional Application No. 1, filed February 21, 2017, by R. Lind, M. Smith, N. Peterson, B. Goreding, M. Brudevold, and M. Theisen, entitled "Adaptive Hot Melt Feed". 62 / 461,536 interests. technical field [0003] The present invention relates generally to hot melt supply and dispensing systems, and more particularly to adaptive hot melt supply systems. Background technique [0004] Hot melt systems are commonly used in manufacturing assembly lines to provide adhesive for the construction or closure of packaging materials (eg, boxes, cartons, etc.). A traditional hot melt dispensing system can include a material supply system and a hot melt dispensing system. The material supply system can deliver the hot melt adhesive pellets to the hot melt dispensing system, which in turn heats and melts the hot melt adhesive pellets to produce a liquid adhesive. When the volume of molten mater...
