US 2022/0274792 A1 · CONVEYING DEVICE AND ANALYSIS SYSTEM

Abstract

A conveying device conveys a container including a magnetic body to a target position along a conveyance path and includes a conveyance surface configured by arranging a plurality of magnetic poles including a core and a coil, and including a conveyance path, a drive unit supplying a current to the coil, and a position detection unit estimating the position of the container. The position detection unit excites a first magnetic pole to detect the position of the container and applies a voltage to at least one second magnetic pole that is peripheral in a predetermined range from the first magnetic pole and is different from the first magnetic pole in a direction in which the polarity becomes opposite to the exciting current of the first magnetic pole, and a process of estimating the position of the container based on the current value of the first magnetic pole.

Dependent claims

A conveying device that conveys a conveyance container including a magnet or a magnetic body to a target position along a conveyance path, comprising:

a conveyance surface configured by arranging a plurality of magnetic poles including a core and a coil, and having a conveyance path;
a drive unit for supplying a current to the coil;
and
a position detection unit for performing a process of estimating the position of the conveyance container, wherein
the position detection unit performs:
a process of exciting a first magnetic pole selected to detect the position of the conveyance container, and applying a voltage to at least one second magnetic pole that is a peripheral magnetic pole within a predetermined range from the first magnetic pole and is different from the first magnetic pole in a direction in which the polarity becomes opposite to the exciting current of the first magnetic pole, and
a process of estimating the position of the conveyance container based on a current value of the first magnetic pole.
