Rolling wheel type transporter

Abstract

A roller conveyor that transports large panels such as liquid crystal panels. It has a plurality of moving wheels (11), and long driving moving wheel axles (10) with a length corresponding to the width of the transported object G are arranged side by side in the longitudinal direction of the frame. The bearing (5) is provided on the driving side of each driving moving axle (10) close to one side in the width direction of the object to be conveyed, and is provided at a position close to the other end of the moving axle (10) away from the other side in the width direction of the object to be conveyed. The bearing (5) supports each driving moving axle (10) at two points. The two ends of the moving axle (10) are extended from the bearings provided on the driving side and the driven side to reach a prescribed length at the wide end of the conveyed object to drive the above-mentioned drive. Move the axle (10). The driving moving axle is formed by a protruding beam extending from the bearing near the other end to a predetermined length of the end edge in the width direction of the object to be conveyed, so that the maximum deflection between the bearings and the deflection of the protruding end are consistent.

Description

technical field [0001] The present invention relates to a roller conveyor in which both ends or one end of a driving and moving wheel shaft extend out and are supported by two points in a roller conveyor for conveying large flat panels such as liquid crystal panels and plasma displays. Background technique [0002] Such as Figure 20 As shown, the roller conveyor for high-speed transport of large thin flat glass (conveyor) G such as liquid crystal panels or plasma display glass substrates has a plurality of moving wheels 51, and is arranged side by side along the length direction of the frame corresponding to the conveyed The long-dimensioned driving axle 50 of the width of the object G; the driving side frame 53 and the driven side frame 54 are relatively arranged on the base 52, and the bearings 55, 55 that are arranged on the above-mentioned frames 53, 54 are formed. Two points support the structure of each driving moving axle 50 . A motor 56 is assembled inside the driv...

AI Technical Summary

Problems solved by technology

[0016] As mentioned above, adopting the structure of increasing the shaft diameter or setting bearings in the middle part outside the two ends to form a three-point support driving the moving axle (or moving axle), there are the following problems respectively: or by increasing the axle diameter to achieve Balance of shaft weight and section properties so that the shaft cannot form too long; or generate dust from the central bearing of the three-point support
