Patent number: 5826696Abstract: In an apparatus for inspecting small articles, such as in particular tablets, for obtaining a precise lining up of the articles there is a rotationally symmetrical separating body (4) rotatable about a vertical rotation axis (A), which has a substantially conical feed section (6) and a section (7, 8) for orienting and/or separating the articles (G) surrounded by a ring slot (S) at least corresponding to the thickness of the articles (G). The separating section (8) is subdivided into individual shafts (11) for receiving the articles (G) by ribs (9) circumferentially succeeding one another with a spacing at least corresponding to the width or diameter of the articles (G).Type: GrantFiled: August 10, 1995Date of Patent: October 27, 1998Assignee: Walter Grassle GmbHInventors: Michael Rupp, Werner Schiffer, Gyula Varhaniovsky, Thomas Kirchner, Nikolaus Asteriadis
