Definitions

• the present invention relates to a piston handling assembly, particularly developed for use in instant beverage preparation equipment and machines. More preferably, the piston movement assembly according to the present invention is comprised of technical, constructive and functional aspects specially designed to ensure accurate, safe and effective locomotion of the piston as well as controlling and ensuring the positioning of said piston. , so as to provide adequate crushing of the beverage capsules during the preparation process thereof.
• This movable element used in instant beverage equipment and machinery can be actuated in a variety of ways and with different technologies, but conventionally use electric motors that drive a kind of endless spindle or thread that carries a plunger with a constructivity designed to contact the capsules and process them, and in some cases gear sets, reducers, pulleys or other auxiliary components are available to promote displacement of the piston or piston.
• Another drawback of positioning sensor positioning only at the beginning of the piston stroke is when a failure occurs during processing and brewing, more particularly during movement of said piston. For example, should the supply of electrical power, or the electric motor breaks down and needs to be replaced. With only the sensor available at the start of travel, when the drive set is restarted, it will not know exactly where it has been positioned or where it has stopped and needs to restart, resulting in equipment malfunctions.
• the placement of the positioning sensor only at the beginning of the stroke restricts and affects the regulation and operation of equipment and machines and thus requires constant maintenance which eventually becomes unpleasant to users.
• the present invention aims to propose a plunger movement assembly, developed particularly for application in instant beverage preparation equipment and machines, comprising technical and constructive features designed and developed. to simply and efficiently solve and improve the drawbacks and restrictions identified in the piston drive assemblies of prior art equipment and machines as discussed above.
• the assembly according to the present invention is intended to ensure proper fulfillment of the function of the plunger in promoting proper crushing of the beverage capsule and thereby to ensure that the contents of said capsules have been properly and suitably poured to obtain the beverage under the desired conditions.
