Abstract

A cyclone separator for a powder recovery device of a powder coating system includes an inlet region with an inlet for a mixed flow of powder/air, a separation region adjoining the lower end region of the inlet region for the centrifugal separation of at least a portion of the powder contained in the mixed flow, and a powder collecting region connected or connectable to the lower end region of the separation region for collecting the powder separated in the separation region. The powder collecting region is shiftable relative to the separation region between a first position in which the powder collecting region is aligned in flush connection with the lower end region of the separation region and a second position in which the powder collecting region is not aligned in flush connection with the lower end region of the separation region.

First claim

The invention claimed is:

1. A cyclone separator for a powder recovery device of a powder coating system, wherein the cyclone separator comprises:
an inlet region with an inlet for a mixed flow of powder and air;
a separation region adjoining a lower end region of the inlet region for the centrifugal separation of at least a portion of the powder contained in the mixed flow; and
a powder collecting region connected or connectable to a lower end region of the separation region for collecting the powder separated in the separation region,
wherein the powder collecting region is shiftable relative to the separation region between a first position in which the powder collecting region is aligned in flush connection with the lower end region of the separation region and a second position in which the powder collecting region is not aligned in flush connection with the lower end region of the separation region and in which access to an interior of the separation region and/or inlet region of the cyclone separator is possible via the lower end region of the separation region, wherein the cyclone separator further comprises an illuminating device with at least one light source, wherein the illuminating device is designed to illuminate or light up at least sections of the interior of the separation region and/or the inlet region of the cyclone separator with the at least one light source when the powder collecting region is in its second position,
wherein the at least one light source of the illuminating device is arranged outside of the separation region and the inlet region of the cyclone separator,
wherein the illuminating device is designed such that:
the at least one light source of the illuminating device switches on automatically and/or can be switched on manually when the powder collecting region is in its second position and/or when the powder collecting region shifts into its second position,
wherein the cyclone separator comprises a limit stop for defining the first position of the powder collecting region and limiting a pivoting movement of the powder collecting region relative to the separation region when the powder collecting region shifts from its second position into its first position, and
wherein the limit stop has a locating surface at least partially formed from an elastomer and/or magnetized material which is held by a bar-shaped mount thereof, wherein the illuminating device has a bar-shaped mount, wherein the at least one light source is provided at a first end region of the bar-shaped mount of the illuminating device, and wherein a hinge joint connected to the bar-shaped mount of the limit stop is formed on a second end region of the bar-shaped mount of the illuminating device.

2. The cyclone separator according to claim 1 , wherein the illuminating device is designed such that:
the at least one light source of the illuminating device switches off automatically and/or can be switched off manually when the powder collecting region is in its first position and/or when the powder collecting region shifts into its first position.

3. The cyclone separator according to claim 1 ,
wherein the at least one light source is arranged and aligned relative to the separation region and the inlet region of the cyclone separator such that at least 50% of the light emitted by the at least one light source of the illuminating device strikes an interior wall area of the separation region and/or the inlet region of the cyclone separator in the second position of the powder collecting region.

4. The cyclone separator according to claim 1 ,
wherein the illuminating device is shiftable relative to the separation region between a first position, in which the at least one light source can illuminate or light up at least part or areas of the interior of the separation region and/or inlet region of the cyclone separator via the lower end region of the separation region, and a second position in which the powder collecting region is in its first position and lighting or illuminating of at least part or areas of the interior of the separation region and/or inlet region of the cyclone separator via the at least one light source is prevented.

5. The cyclone separator according to claim 4 ,
wherein the illuminating device is designed such that:
(i) the illuminating device is only shiftable from its second position into its first position when the powder collecting region is in its first position; and/or
(ii) the illuminating device independently shifts from its first position to its second position when the powder collecting region is shifted from its second position to its first position; and/or
(iii) the at least one light source of the illuminating device is automatically switched on and/or can be manually switched on when the illuminating device shifts from its second position to its first position; and/or
(iv) the at least one light source of the illuminating device is automatically switched off and/or can be manually switched off when the illuminating device shifts from its first position into its second position.

6. The cyclone separator according to claim 4 ,
wherein the powder collecting region is pivotable between its first position and its second position in a horizontal pivot plane relative to the separation region, and wherein the illuminating device is pivotable between its first position and its second position in a horizontal pivot plane relative to the separation region, wherein the horizontal pivot plane of the illuminating device coincides with the horizontal pivot plane of the powder collecting region or is in immediate proximity to the horizontal pivot plane of the powder collecting region.

7. The cyclone separator according to claim 1 ,
wherein the cyclone separator comprises a support frame via which the inlet region and/or separation region of the cyclone separator is/are at least partially supported, wherein the powder collecting region is pivotably mounted to the support frame via a first joint assembly, and wherein the illuminating device is pivotably mounted to the support frame via a second joint assembly separate from the first joint assembly.

8. The cyclone separator according to claim 1 ,
wherein an edge protector is formed on the first end region of the bar-shaped mount of the illuminating device, and wherein the rotational axis of the hinge joint lies on an outer edge of the bar-shaped mount of the limit stop.

9. The cyclone separator according to claim 1 ,
wherein at least the lower end region of the separation region is frustoconical with a shell geometry that conically tapers toward the powder collecting region, wherein the powder collecting region is provided with a shell geometry which tapers conically toward a powder outlet at the lower end region of the powder collecting region, wherein in the first position of the powder collecting region, the powder collecting region is pneumatically, hydraulically, electrically or manually movable in a longitudinal direction of the cyclone separator relative to the separation region such that an outlet opening of the separation region is connectable to an inlet opening of the powder collecting region.

10. A cyclone separator for a powder recovery device of a powder coating system, wherein the cyclone separator comprises:
an inlet region with an inlet for a mixed flow of powder and air;
a separation region adjoining a lower end region of the inlet region for the centrifugal separation of at least a portion of the powder contained in the mixed flow; and
a powder collecting region connected or connectable to a lower end region of the separation region for collecting the powder separated in the separation region,
wherein the powder coll
