Levitation transportation device and levitation transportation method

Abstract

A levitation transportation device capable of adjustment when an object being transported is displaced from the center of a transportation path, A levitation transportation device having a transportation path forming a transportation router for an object to be transported, a plurality of jetting nozzles for transporting the object in a levitated manner along the transportation path, one or more detection sections for detecting the direction of the transportation of the object being transported in the transportation path and a control section for independently controlling the plurality of jetting nozzles based on a detection result by the detection sections.

1 . A levitation transportation device, comprising:
 a transportation path forming a transportation route for an object to be transported;   a plurality of jetting nozzles for transporting the object in a levitated manner along the transportation path;   at least one detection section configured to detect a direction of the object being transported in the transportation path; and   a control section for independently controlling the plurality of jetting nozzles based on a detection result of the detection section.   
   
   
       2 . The levitation transportation device according to  claim 1 , further comprising:
 a line sensor having a detection range crossing a direction of the transportation path and across an entire width of the transportation path.   
   
   
       3 . The levitation transportation device according to  claim 1 , wherein the control section, based on the direction of the object detected by the at least one detection section, controls a jetting pressure of a pressure gas jetted from the jetting nozzles such that the object being transported is returned to a center of the transportation path. 
   
   
       4 . The levitation transportation device according to  claim 1 , wherein the control section, based on the direction of the object detected by the at least one detection section, controls a jetting pressure of the pressure gas jetted from the jetting nozzles such that the object being transported is not displaced from a center of the transportation path. 
   
   
       5 . A levitation transportation method, comprising:
 transporting an object using a levitation transportation device, the levitation transportation device comprising a transportation path forming a transportation route for an object to be transported, a plurality of jetting nozzles for transporting the object in a levitated manner along the transportation path, at least one detection section configured to detect a direction of the transportation of the object being transported in the transportation path, and a control section for independently controlling the plurality of jetting nozzles based on a detection result of the detection section.   
   
   
       6 . The method according to  claim 5 , wherein the levitation transportation device further comprises a line sensor having a detection range crossing a direction of the transportation path and across an entire width of the transportation path. 
   
   
       7 . The method according to  claim 5 , further comprising:
 controlling a jetting pressure of a pressure gas jetted from the jetting nozzles based on the direction of the object detected by the at least one detection section so that the object being transported is returned to a center of the transportation path.   
   
   
       8 . The method according to  claim 5 , further comprising:
 controlling a jetting pressure of a pressure gas jetted from the jetting nozzles based on the direction of the object detected by the at least one detection section so that the object being transported is not displaced from a center of the transportation path.
