Embodiment Construction

[0052] Such as figure 1 and figure 2 As shown, the powder supply system for a powder coating plant according to the invention comprises a tank 2 for containing powder. The system comprises means for detecting the amount of powder in the tank 2 , for example consisting of means 3 for weighing the mass of the tank 2 .

[0053] The system also includes a transfer device for transferring the powder into the tank. The conveying device includes a conveying pipe 4 for conveying powder to the tank 2 and a supply valve 5 for blocking the powder conveying pipe 4 . The supply valve is a pinch valve type.

[0054] The transfer pipe 4 is connected downstream of a loading device, not shown, in particular a filling container.

[0055] The transfer pipe 4 is arranged approximately horizontally and the powder supply valve 5 is arranged near the horizontal section of the pipe, which prevents compaction of the powder near the valve 5 due to gravity.

[0056]At the downstream end of the tra...

Abstract

The invention relates to a powder supply system for powder coating plants, in particular for parts coating plants using electrostatic powders, according to the invention comprising a tank (2) designed to contain powder, for feeding the powder means (4, 5, 6) for supply to the tank (2), means (15, 14) for injecting compressed air into the bottom of said tank (2) in order to fluidize the powder, and the powder is air- A discharge pipe (8) entrained from the tank (2), this pipe (8) is connected to at least one remotely located powder application device, in particular a spray gun (9). The system also comprises means (16, 17, 18, 19).

Description

technical field [0001] The invention relates to a system for supplying powder to a powder coating plant, in particular a spraying plant for spraying components with electrostatic powder, and to a method for supplying powder to a powder coating plant. Background technique [0002] Powder coating plants provided with a powder spraying device usually have a conveying device for moving the parts to be coated in front of the spraying device. Depending on the size and shape of the individual components it is necessary to adjust the flow rate of the powder sprayed by the spraying device in a suitable manner. Therefore, the spraying device needs to be supplied from a remote location with a controllable and adjustable flow rate of powder which is fluidized and delivered by compressed air. Thus, the flow of powder can advantageously be measured, the powder mixed with compressed air and the air / powder mixture transported to the powder supply device in order to feed the spraying device...
