Taking the embodiment shown in Figures 1-5 as an example, the working process of the reversing conveying equipment will be described below.

Before starting to work, the position of the belt conveying assembly 31 is lower than that of the conveying roller 11, for example, 5-10 mm lower. When reversing conveying operation is required, according to the work order of the production line control system, the roller conveyor system 1 is first started, and after the glass is conveyed to the designated position by the conveying roller 11, the conveying roller 11 stops rotating. The exhaust fan 41 starts to generate negative pressure. The lifting system 2 is activated to make the belt conveying system 3 rise, and the belt conveying assembly 31 is higher than the conveying rollers 11 arranged alternately with it, and lifts the glass resting on the conveying rollers 11 . Subsequently, the lifting system 2 stops working, for example, when the belt conveying section is 5-10mm higher than the conveying surface of the roller table. The belt conveying system 3 is started, and the glass is conveyed in a direction perpendicular to the conveying direction of the roller conveying system 1 under the state of negative pressure, realizing the reversing conveying of the glass. After the belt conveying system 3 stops working, the lifting system 2 runs in the opposite direction, so that the belt conveying system 3 returns to the initial position, and waits for the next reversing conveying operation.

It is also possible on the mechanism, and it can also realize reversing conveying.

It can be known from the foregoing functional description that the reversing conveying equipment provided by the present invention can also be used for conveying other materials or articles, not limited to glass substrates.

As can be seen from the above description of the embodiment of the present invention, since the vertical lifting mechanism of the lifting system of the present invention adopts a straight-up and straight-down operation mode of lifting, the possibility of lateral movement of the glass during the reversing process is reduced, and the glass and the belt are reduced. The friction of the glass reduces the damage of the glass; when the belt with negative pressure is used for conveying, the glass substrate is transported by the belt, on the one hand, the glass is turned and conveyed more stably, and the possibility of lateral movement of the glass is further reduced On the other hand, it also avoids the damage of the glass substrate due to the jumping of the breaking force, and can achieve the purpose of stable breaking and conveying; the uniform and small distance between the roller table and the belt distance can realize the glass substrate from the small glass size to the large glass size The transportation; the lifting system adopts the H-type four ball screw lifting platform configuration, the power demand is small, energy saving, and it is easy to ensure the flatness of the lifting platform.

The above-mentioned embodiments only illustrate the principles and effects of the present invention, but are not intended to limit the present invention. Anyone skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention.
