Abstract
Official abstract text for this publication.
Provided is a transport device in which reliability is increased by suppressing deterioration of the transport surface and transport efficiency is increased by suppressing electrical current loss. A transport device 1 comprising a transported body having either a permanent magnet 10 or a magnetic body, and an electromagnet unit in which coils 21 are wound around teeth 25 comprising magnetic bodies, and having recesses on surfaces of the teeth 25 facing the transported body. Specifically, the surfaces of the teeth 25 facing the transported body have at least two surfaces (first facing surface 22, second facing surface 23, etc.) which have different distances to the transported body.
First claim
Opening claim text (preview).
What is claimed is: 1 . A conveying device, comprising: a conveyed object having a magnet or a magnetic material; and an electromagnet unit formed by coiling wire around teeth comprised of a magnetic material, wherein the conveying device has a recess on a surface of each of the teeth facing the conveyed object. 2 . The conveying device according to claim 1 , wherein the surface of each of the teeth that faces the conveyed object comprises at least two surfaces having different distances from the conveyed object. 3 . The conveying device according to claim 1 , wherein the surface of each of the teeth that faces the conveyed object comprises a first facing surface close to the conveyed object and a second facing surface far from the conveyed object, and wherein the first facing surface is on an outer diameter side than the second facing surface. 4 . The conveying device according to claim 1 , wherein the surface of each of the teeth that faces the conveyed object comprises a first facing surface close to the conveyed object, a second facing surface far from the conveyed object, and a third facing surface a distance of which from the conveyed object is intermediate. 5 . The conveying device according to claim 4 , wherein a distance of the third facing surface from the conveyed object varies gradually from the first facing surface to the second facing surface. 6 . The conveying device according to claim 1 , wherein the surface of each of the teeth that faces the conveyed object comprises a first facing surface close to the conveyed object and a second facing surface far from the conveyed object, and wherein the second facing surface is formed linearly. 7 . The conveying device according to claim 1 , wherein the surface of each of the teeth that faces the conveyed object comprises a first facing surface close to the conveyed object and a second facing surface far from the conveyed object, and wherein the second facing surface comprises a plurality of surfaces that radially extend from a center to an outer diameter side. 8 . A sample analysis system having a conveying device according to claim 1 , wherein the conveyed object is a holder or a rack to retain a sample container.
