Description
Technical field
The present invention relates generally to coating applicators, especially, the present invention relates to be suitable for fast the electrostatic sprayer of the various different coating of spraying continuously.
Background technology
Automatically spray applicator expects that being coated with of spraying number of different types this respect on the object has the scope of application of broad in manufacture process.For example: the body portion of automobile is had robot device's coating of spray applicator usually.Robot is programmed and carries out a series of action, and body portion is covered fully and accurately with the fast method of minimum waste coating.
Spray applicator is often used in the amount that reduces overatomize, cuts the waste further.In known spray applicator, the cup of toroidal is with rotation at a high speed, and coating material for example paints then, is provided to the cup inside of toroidal.When paint or other coating move to the toroidal cup in appearance and because centrifugal force when breaking away from the surface, coating is atomized into tiny mist of oil and is sprayed directly on the object.As everyone knows, air stream straight along the appearance of cup to the border and the coating that is atomized of guiding towards coated object.Everybody also knows, owing between charged mist and the object of preparing coated ground connection electromotive force is arranged, therefore, coating material attracted on the object, further reduces the coverage rate that overspray and improvement are coated to erose target object.
In existing processing method,, part color transfer sequence is at random arranged along production line such as body of a motor car.Therefore, for each coated object, the coating type that changes painting color or be used for an object is necessary.30 kinds or more kinds of different color may be suitable for buying the consumer of automobile, and all may be necessary in any color of any point of manufacture method for the object of the coating before being placed on robot.Preferably to lack from the time that a kind of coating switches to another kind of coating, so that the performance of spray robot does not constitute the limiting factor of an important manufacturing speed on assembly line.A useful system, changing the required time of coating should be no longer many to the time of spraying position than transmitting a complete object and transmit next target object from the front of robot.
Suggestion is used and is had a series of interchangeable flush coaters that the container of various types of coatings is housed, as the paint of different colours.Between coating spraying, applicator relinquishes one empty and accept a full container that is used for next object that suitable coating is arranged.One fluid hose stretches out and is inserted into by flush coater near the inside of the broadening formation cup that is used to supply the coating broadening formation cup and is used for atomizing subsequently from container.Yet, to insert and move and the pipe of container one may be heavy, and pipe is placed on one when being large enough to hold in the passage of pipe, the position of pipe may be very at random.So supplying to the bell-mouthed coating of atomizing also can be more or less at random with inconsistent.Also have, if a kind of special coating is without commonly used, and the container that comprises this coating do not use for a long time, and being kept in the said vesse coating in the pipe on a small quantity may hardening, also may block pipe.
In the system of another suggestion, container is constrained in the storage vault of a container.Each container is filled dissimilar coating, and can be placed on selectively in the supply lines that is communicated with the flush coater fluid, and directly is not attached to or is installed on the flush coater.
When coating is assigned with or when container was filled once more by coating, the structure of the above-mentioned container of mentioning may encounter problems.In a kind of structure, container has one be the wall of rigidity substantially what internal tank slided, when coating is assigned with reducing volume, and when coating is added in the container increase volume.Interface between the installed surface of sliding wall and container keeps water-tight seal to meet difficulty.In other words, further, when sliding wall slided in container when sliding wall, the surface of sliding wall had constituted a part of coating volume and a part of non-coating volume.When container was poured out coating, the film of coating remained on the sliding wall.If container is full of dissimilar coating, remaining film will pollute new coating.If sliding wall moves by the fluid that a dielectric feed fluid is pumped in the container, paint film on sliding wall pollutes the fluid of feed, and if coating conduct electricity, then change the dielectric property of feed fluid subsequently.
The multiple structure that utricule or insert are arranged that other has been used all has effect in various degree.The container of a flush coater that is used to spray is necessary, and it can be unloaded fast and connect, and the empty container of change is filled up between the step of using apace fully.
