Abstract:
The invention device measures the instantaneous rotation speed of a turbine (6) which is housed inside the body (3) of the paint sprayer (2) and which rotationally drives the rotating bowl (5) when the paint sprayer is mounted on the end of an arm (8) of a robot or an analogous multi-axis machine. A disk (10) which is disposed to the rear of the turbine (6) and which rotates therewith, cooperates with the front end (11a) of an optical-fiber-type light guide (11) which is interrupted (11b) at the rear (7) of the body (3) of the paint sprayer (2). Transmitting and receiving optoelectronic means are mounted on the end of the arm on the mounting pane (9) of the paint sprayer, opposite the rear end (11b) of the light guide (11). Said means covert a reflected optical signal which is carried by the optical guide (11) into an electronic signal which is carried by an electric cable (22) placed in the arm (8). The inventive device is suitable for use with machines on automatic painting lines for automotive vehicles.
Abstract:
A material spreader assembly for the broadcast spreading of particulate material from the trailer hitch of a vehicle. A hopper for storing the particulate material is supported by a frame having a trailer hitch coupler for connection to the vehicle. A spreader including a spinner driven by an electric motor receives and disperses the particulate material. A control circuit receives electric current from the vehicle via a plug interface and a wiring harness and controls the operation of the spreader. A remote communicates user commands to the control circuit. The control circuit includes a motor control processor that controls a motor power relay and a motor driver to gradually ramp up the current supplied to the spreader for start up the spreader while preventing a high transient current draw spike. Component feedback sensors enable the motor control processor to provide an emergency shut off feature and warning signals.
Abstract:
The invention relates to an electrostatic projector (P1) comprising: an insulation body (1); a rotatably movable projection member (2); rotational driving means (7); high-voltage power supply means (26); conducting elements (2.1, 6, 22, 23); a detection device (40) for evaluating the rotation speed of the projection member (2), the detection device (40) including at least one target (41, 42) on a rotary component and a sensor (43) adapted for detecting the or each target. The projector (P1) further includes at least one insulating wall (50) that defines a housing (51) surrounding the sensor (43) for insulating the entire sensor (43) from the conducting elements (2.1, 6, 22, 23). The sensor (43) is separated from the space (V) scanned by the rotating target (41, 42) by an essentially axial detection distance (H).

Abstract:
An irrigation sprinkler is for use in distributing water to an area of vegetation, and has a rotatable nozzle for dispersing the water by rotation of the nozzle. A magnet is coupled or connected to the nozzle and rotates synchronously with the rotation of the nozzle. A sensor unit is disposed adjacent to the nozzle and detects a magnetic field generated by the magnet during nozzle rotation to generate a signal indicative of the speed and direction of rotation of the nozzle.

A method for conducting diagnostic tests of spray equipment in a hazardous environment. The method includes automatically gathering test data, comparing the automatically gathered test data to a database of baseline data, and providing a signal if the automatically gathered data differs from the baseline data by a predetermined amount.

Abstract:
A rotary atomizer for atomizing a coating material for the coating of workpieces having a housing, a turbine wheel which is arranged in the housing and can be driven in two directions of rotation, a bell cup can be set in rotation by the turbine wheel about an axis of rotation and also a device for determining a rotational speed, wherein the device comprises an optical waveguide and a disc, which is indirectly or directly connected to the bell cup or the turbine wheel for rotation therewith and has an optically detectable structure, wherein the optical waveguide is designed for recording the optically detectable structure and for passing on the recorded structure as an optical signal in the housing. The optical waveguide has a first information channel and a second information channel, which are respectively designed for passing on an optical signal independently of one another.
Abstract:
Exemplary illustrations of a bell cup for a rotary atomizer and method of using the same are disclosed. The exemplary illustrations are generally directed to the control of the rotating bell plate of a rotary atomizer used for the serial coating of work pieces. An air flow component may be created by the structural design of the bell plate and/or of an element of the rotary atomizer and by the rotation of the bell plate. The air flow component may correspond to the bell plate design, and the element may be adjacent to the bell plate and stationary relative to same. The air flow component may be measured and compared to a predefined reference value.
Abstract:
A rotary atomizer has an internal power supply in the atomizer housing about which is passed cooling air. The air then flows out of the atomizer housing in a twisting direction as vectored air in the same direction of rotation as the atomizer head to eliminate any vacuum condition around the atomizer head and to provide shaping control of the coating being sprayed. A portion of the exhaust air from an air turbine motor driving the atomizer head with a turbine shaft is directed through a passageway between a stationary fluid tube within the turbine shaft and the rotary shaft to direct the exhaust air into the atomizer head to mix with the coating and create an air barrier that prevents coating material from leaking back into the rotary atomizer device. The remaining portion of the exhaust air from the air turbine motor is channeled around the outside surface of the housing of the rotary atomizer device to prevent liquid coating material from wrapping back and attaching to the atomizer housing.
