Embodiment Construction

[0013] One embodiment of the present invention will be described below with reference to the drawings. In this specification, claims, and drawings, front, rear, left, and right are defined as directions of FF, FR, L, and R respectively marked in the drawings. The so-called definitions are for convenience of description, and the present invention is not limited thereto.

[0014] refer to Figure 1 to Figure 5 , The floating conveyance device 1 according to one embodiment of the present invention is a device that floats the object W in the vertical direction and conveys it in the horizontal conveyance direction (for example, the rear FR). The object W is a thin object that is planar as a whole, and for example, a thin plate such as a glass substrate for LCD (liquid crystal display) is suitable. The object W does not have to be flat as a whole, and at least a part of its lower surface should be flat. A fluid such as air is used for flotation.

[0015] When the object W must b...

Abstract

The present invention provides a floating conveyor which floats an object for conveying and comprises the following components: a plurality of floating devices and each of which comprises an upper surface, a spraying-out opening which is provided on the upper surface for spraying out the fluid, and a fluid supplying device which pressurizes the fluid and supplies to the spraying-out opening through a flow path; a communicating path which is communicated with the flow path; a sensor for detecting the pressure in the communicating path; a conveying device for conveying the object; and a controller for determining the pressure abnormity according to the output of the sensor.

Description

technical field [0001] The present invention relates to a floating conveyance device that floats and conveys an object using fluid such as compressed air. Background technique [0002] Many floating transport devices have been proposed that use fluid such as compressed air to float and transport an object. Typically, these floating transport devices include: an air supply device such as a fan or a blower for supplying a fluid such as air; and a floating device having a discharge hole through which the fluid can pass. The fluid injected between the floating device and the object generates pressure, and the object floats by the pressure. The floating object is transported by the driving force of the transport device. Related techniques are disclosed in Japanese Patent Application Publication No. 2006-182563. [0003] Generally, a floating conveyance device has a plurality of floating devices arranged in parallel along the direction in which an object is conveyed. The suppl...
