Abstract:
A powder coating control system comprising a plurality of gun controls associated with a like plurality of powder spray guns. Each of the gun controls stores a plurality of presets spray parameters. Each of the gun controls responds to part identification signals and part position signals to select in real time one of the stored presets of spray parameters and trigger its respective powder spray gun ON and OFF to apply a powder coating to the moving part in accordance with the selected set of spray parameters. The control system further permits a gun purge cycle to be programmed either before or after the powder coating process is executed. The control system automatically initializes and brings each of the gun controls to an operable state on-line with the system control.
Abstract:
An apparatus is disclosed for the automatic coating of articles. The apparatus has a spray device controlled by a programmed control device. A transport device transports the articles along a predetermined path to a coating position and then away therefrom after coating. A sensor monitors the position of the article and generates signals representative thereof, preferably generating one signal each time the article moves a predetermined distance (e.g. 2 cm.) along the path. A second sensor generates additional signals to the control device when an article passes a predetermined point, also indicating which of several types of articles has been detected. The control device controls the spraying process responsive to these signals. If desired, portions of the article that are moved sequentially into the coating position can be sprayed in different manners, e.g. with the spray devices positioned or oriented differently, or using different coating materials, etc. The control device is preferably reprogrammable.
Abstract:
Method of making a self-locking threaded element, e.g. a screw including a strongly adhered convexly curved plastic body on its threaded surface allowing smooth assembly and giving strong frictional engagement between the element and a mating threaded surface. In the method, a stream of fine particles of heat-softenable plastic is directed against a threaded surface portion of a heated metallic element. Contacting particles are caught on the heated surface and fused by heat from the element to form a continuous plastic body which is then hardened by cooling.
Abstract:
A process and apparatus are provided for spray coating an annular race or seam on a motor vehicle wheel or the like. The apparatus includes a spraying device and a conveyor carrying a frame for supporting the wheel in a vertical position; the spraying device has a first carriage adapted to engage and move horizontally with the frame, a second carriage supported by the first carriage adapted to move towards and from the frame and a third carriage supported by the second carriage and adapted to move vertically therefrom; the third carriage being a spray head and carrying rollers adapted to remove the wheel from its support on the frame and to rotate it in front of the spray head.
Abstract:
A vertically retractable rotatable bottle chuck attachable to a belt of an overhead chuck conveyor comprises a first support plate having at least one protruding lock pin with a recess in its exposed periphery and a second support plate having at least one mating orifice for receiving each aligned lock pin and release means intersecting each orifice for releasably engaging a lock pin recess, one of the plates supporting the bottle chuck and the other of the plates being attachable to the belt of the overhead chuck conveyor.
Abstract:
A plastic powder spray station is disclosed through which bottles to be spray coated are carried by a continuously moving overhead chain conveyor from which are suspended neck gripping bottle chucks. Cam operated means on a parallel conveyor, driven in synchronism with the bottle conveyor, operates chuck covering means which sense the presence or absence of a bottle in each chuck before entering the spray station, and covers empty chucks to prevent their fouling by sprayed plastic while passing therethrough. The covers are removed by caming means following exit from the spray station. The foregoing abstract is not to be taken either as a complete exposition or as a limitation of the present invention, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be had to the following detailed description and the accompanying drawings as well as to the claims.
Abstract:
Apparatus for treating the surfaces of elongated bodies, especially sheet metal bodies of automotive vehicles, comprising a plurality of upright dip tanks arranged in a row and each containing a treating liquid. Guide rails are arranged above the row of tanks and conveying and hoisting means are provided movable along the guide rails for suspending a body at one end in vertical position and for moving the body in vertical position and in vertical direction successively into the tanks to be submerged in the liquid therein. The apparatus includes preferably also spraying means for spraying the bodies with treating liquids while they are at least partly withdrawn from the respective tank.
