Abstract:
A coating such as liquid milk chocolate is applied to articles such as confectionery bars. The bars are conveyed by conveyor under a curtain of liquid chocolate issuing through an outlet slot in a trough. A layer of air is caused to flow through the outlet slot in the trough so as to modify the flow characteristics of the curtain. The layer of air permits a curtain of even thickness to be achieved.
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 device for gel-coating seeds includes: a plurality of nozzles into each of which a gelling agent is filled and a seed is charged and held in the gelling agent to form a gel-coated seed; a pair of upper and lower nozzle casings joined with each other through a joint surface; galleries for the gelling agent formed on the junction surface; and passages formed in the lower nozzle casing which extend from the respective galleries to the respective gel-filled portions of the nozzles below the galleries. The nozzles vertically penetrate the upper and lower nozzle casings which may be comprised of a bottom plate and nozzle sleeves. The joint surface is arranged higher than a gel-filled portion of each nozzle.
Abstract:
Method and system for encapsulating a coil are provided. In one exemplary embodiment, the method allows providing a chamber for performing at least one manufacturing operation in connection with at least one coil to be encapsulated. The method further allows providing a pallet for supporting the at least one coil to be encapsulated. The pallet may be mounted on a conveyor configured to move the pallet in the chamber proximate to a nozzle configured to dispense encapsulant to the at least one coil. A vibration generator may be mechanically coupled to the conveyor. The vibration generator is electrically responsive to command signals from a controller. The command signals may be based on a vibration profile configured to controllably vibrate the at least one coil so that the encapsulant may flow assisted by the vibration through passages in the coil notwithstanding of a dimensional tightness of the passages therein, and thereby reduce the possibility of faults that could otherwise develop due to poor flow of the encapsulant.
Abstract:
A method and apparatus for coating a work piece. The system comprising an applicator adapted to travel over a portion of the work piece. The system being operable to heat the work piece and/or apply a coating onto the work piece as the applicator travels over the work piece. The system may comprise an induction heating system to heat the work piece. The system may be adapted to apply a variety of coatings, such as a liquid coating and a dry powder coating. The applicator being operable to heat the work piece prior to applying the coating or heating the work piece after the coating has been applied. The applicator may also be adapted to apply heat to heat shrink a coating material onto the work piece.
Abstract:
There is provided a deposition system (1) for yielding substantially uniform deposition of an evaporant material onto a substrate. The deposition system (1) comprises: a source (10) for generating a coherent energy beam; a substantially planar target (60) containing the evaporant material and disposed in spaced relation to the substrate; a focusing element (30) optically coupled to the source for focusing the coherent energy beam onto the target (60); and, an actuator (40) coupled to the focusing element (30) for reversibly translating the focusing element (30) along a scanning path directed substantially parallel to a target plane defined by the target (60). The focused coherent energy beam defines an impingement spot (14) on the target (60). The impingement spot (14) is displaced responsive to the translation of the focusing element (30) along the scanning path. The focus of the coherent energy beam on the target (60) thus remains substantially preserved.
Abstract:
A die, having multiple discharge orifices arrayed in a generally straight line for applying an application fluid to an object of application, and an internal application fluid reservoir, wherein braces are provided in the application fluid reservoir and extending in a direction generally orthogonal to the direction of the array of the discharge orifices. Also, an application apparatus and method for application fluid, for relatively moving a base material wherein stripe-shaped vertical barrier ribs are formed on the surface of the base material and horizontal barrier ribs having a height equal to or lower than the vertical barrier ribs are formed in a direction generally orthogonal to the vertical barrier ribs, and a die provided facing the base material, while discharging application fluid from multiple discharge orifices provided on the die, thereby applying application fluid to selected grooves between the vertical barrier ribs of the base material.
Abstract:
On top of respective areas divided by partition plates, that is, a cassette station, a processing station, and an interface section in a coating and developing processing system, gas supply sections for supplying an inert gas into the respective areas are provided. Exhaust pipes for exhausting atmospheres in the respective areas are provided at the bottom of the respective areas. The atmospheres in the respective areas are maintained in a clean condition by supplying the inert gas not containing impurities such as oxygen and fine particles from the respective gas supply sections into the respective areas and exhausting the atmospheres in the respective areas from the exhaust pipes.
Abstract:
The invention relates to an adhesive robot, comprising a device for applying adhesive to a workpiece. The adhesive robot has a nozzle head (18), which has an application nozzle (24) and can be supplied with a pressurized viscous adhesive, the nozzle head (18) and the workpiece (14) being displaceable in relation to one another. The adhesive which is issued from the application nozzle (24) in a spray jet (28) is applied to a workpiece (14) along a predefined line of application (36) in the form of a strip of adhesive (40). To facilitate the adjustment and re-calibration process, the system comprises at least one camera unit (42), which is located on the nozzle head (18) and whose leans is directed towards the spray jet (28) or the adhesive strip (40). The output of said camera unit is connected to an image evaluation unit (45). The image data (40) recorded by the camera unit (42) is buffered and compared with predetermined image values (40). The decisive control parameters for the system can be calibrated and tracked either automatically or by remote control, on the basis of deviations in the image data that have been determined along the line of application (36).
