Abstract
A spiral conveyor has a conveying device that is moved along a helically running spiral region. The conveying device is supported along the spiral region on the radially loaded side of the conveying device. The support is realized by multiple individual deflecting devices that lie along the radially loaded side of the conveying device. Each said deflecting device has a central body including a roller body that surrounds the central body, the roller body including a plurality of rollers. The rollers are rolled on a roller track of the central body in an annular segment of a helically running supporting region of the spiral conveyor.
Claims19
A spiral conveyor, comprising:
- a conveying means moved along a helically extending spiral region, wherein the conveying means is supported on its radially loaded side along the spiral region,
- wherein said support is realized by several individual deflecting devices arranged along the radially loaded side of the conveying means, and
- wherein said deflecting devices each comprise a central body with a roller body circulating around said central body with a plurality of rollers, and the rollers roll along a roller track of the central body in an angular segment of a helically extending support region.
A method for producing a spiral conveyor, said method comprising the following steps:
- producing a central body for a deflecting device and inserting a roller body into the central body, wherein the track of the roller body around the central body lies in a plane,
- assembling the deflecting device as a structural unit in the spiral conveyor, wherein the deflecting device, as it is being installed into the spiral conveyor of the assembly, is deformed.
A deflecting device comprising:
- a central body with a roller body which circulates around the central body, and
- the roller body comprises a plurality of rollers which roll around the central body on a roller track of the central body, wherein the central body is formed by plastic deformation of a profiled rod.
A method for producing a deflecting device, said method comprising the following steps:
- producing a initial profile which comprises a profile cross section that remains substantially the same along its longitudinal direction;
- plastic deforming of the initial profile into a curved and/or twisted form;
- and
- inserting the rollers and assembling end elements for guiding the rollers.
