Problems solved by technology

[0005] The problem on which the object of the invention is based is that the spraying equipment and the associated powder container are changed when changing the powder (changing one powder type for another powder type), especially when changing the color (changing the powder of the first color) powder of a second color) must be cleaned carefully as there are already some small amounts of powder particles of the previous powder type which can cause coating defects when coating with the new powder type

Embodiment Construction

[0021] figure 1 An example embodiment of a powder coating plant 1 according to the solution according to the invention is shown schematically. The powder coating device 1 is used to spray coating powder on an object 2, and the coating powder technique is thereafter figure 1 fused onto the object 2 in a furnace not shown in . In order to control the functions of the powder coating installation 1 one or more electronic control devices 3 are provided.

[0022] A powder pump 4 is provided for pneumatically feeding the coating powder. This can be a syringe into which the coating powder medium is sucked from the powder container by means of compressed air used as feed air, after which the mixture of feed air and coating powder flows together into the container or to the spraying device.

[0023] Suitable syringes are known, for example, from publication EP0412289B1.

[0024] It is also possible to use as the powder pump 4 a pump type which successively feeds a small amount of po...

Abstract

Disclosed herein is a powder container for supplying coating powder to a powder coating station. The powder container includes a powder compartment for coating powder, the powder compartment being delimited by side walls, one of which is provided with an outlet port via which the powder compartment is or can be fluidically connected to an inlet of a powder deposition system. The effective flow cross-section of the fluid connection between the outlet port and the inlet of the powder deposition system can be variably adjusted.

Description

technical field [0001] The invention relates to a powder container for supplying coating powder to a spray coating device. Background technique [0002] The powder container according to the invention is particularly suitable for supplying powder to powder coating installations for electrostatically spraying powder on objects, wherein unused coating powder (hereinafter also referred to as "fresh powder") and, if necessary, recycled The coating powder (hereinafter also referred to as "recovery powder") is located in a powder container and is conveyed by a powder discharge device (for example in the form of a syringe or powder pump, spray device, in particular a spray gun). The spraying device can be, for example, a hand-held spray gun or an automatic spray gun. [0003] As required, the unused powder is transferred from the supplier container to the powder container through the fresh powder pipeline, and the powder supplier provides the unused powder to the powder user in th...
