Definitions

  • Control unit with signaling membrane and automatic control of the discharge of residues, cable app to passenger textile cleaners.
  • the present invention relates to a control unit having a membrane intended to signal and automatically control the time of emptying of textile residues accumulated in the filters of passenger textile cleaners.
  • said unit is characterized in that it works under vacuum or pressure and has the appropriate means to adapt to the corresponding chamber where the separator filter is located and with which the corresponding turbine acts, said membrane being combined.
  • a detector dependent on an electrical circuit capable of activating, automatically, the mechanisms of the cleaner provided for the emptying at the appropriate point of these residues, such as fluff, wires and others, which then detach from this filter, on which they formed a layer which neutralized the action of this turbine.
  • the diaphragm is constantly subjected to the tension of an internal spring which keeps apart, at the rest phase of the assembly, a central contact or stop with adjustable position, situated on said diaphragm, from another fixed contact of the detector and normally mounted at the bottom of a box on the edge of which this membrane is fixed, the electrical circuit then being closed, to which circuit the detector is located when the vacuum or pressure acting on the assembly is sufficiently high, at blockage of the filter, to cause the connection between the con- tackles mentioned above by defeating the tension of the spring interposed between them, the spacing being graduated between said detector and the contact or central stop of the membrane by moving either directly the latter (vacuum operation of the device) or this detector through a socket with differential operation (pressure on the assembly).
  • the unit that is described consists of a membrane (1), of normally circular shape and of variable material, which is applied to the edge (2) of a b8ite (3) using a fixing ring (4).
  • the center of said membrane (1) is occupied by a screw (5), axially open and provided inside with a threaded rod which acts as an adjustment stop (6).
  • a nut (7) remains attached to the inner face of the membrane (1) a casserole (8) which receives the end of a helical spring (9) pressed, by its other end, against the bottom of the box (3), which has several holes (10) for the passage of air and another central for fixing a screw (11) which acts as a detector and which is connected to electrical conductors (12), which are part of a circuit discharge maneuvering device.
  • the membrane unit of FIG. 1 is intended to act under pressure while that of the Pig. 2 is intended to operate under vacuum, however their structure is the same in their basic elements, as can be seen by examining these figures.
  • the membrane of FIG. 1 is installed on the trolley or textile traveler (13) in communication with the chamber (14), where the blades of the turbine (15) are located, that is to say in the pressure zone (Fig. 4) while the membrane of FIG. 2 is mounted on this carriage (13), but in communication with the lower chamber (16), that is to say in the vacuum zone (Fig. 5).
  • the trolley or traveler (13) is provided with the appropriate general filter (17), under which are accumulated the flocks (18) conducted through the chutes (19), to which are connected the suction sleeves which act during movement of the carriage (13) on the rails about (20), supported by the bearing group (21) and with the impulse of the motor (22).
  • the device is completed by a differential adjustment socket (23).
  • the membrane When the membrane is used to operate under pressure (Fig. 1), it is placed in communication with the pressure chamber (14), where the turbine (15) also draws air through the filter (17), by creating a high pressure in this chamber which acts on the membrane (1), which comes into contact with the detector (11), which is automatically connected.
  • the filter (17) When the filter (17) is saturated with residues, we arrive at the minimum suction limit, with which the pressure drops and the membrane (1), when it is free, returns to its initial position and the permanent signal which had been established is canceled. This cancellation is collected by said electrical circuit, which activates, automatically, the mechanisms of the cleaner so that it is drained.
