Pneumatic spiral direction-converted conveyor

Abstract

The invention relates to a technology of a direction conversion device of a manufacturing engineering conveyor line of a glass plate for a liquid crystal display device, in particular to a pneumatic spiral direction-converted conveyor. In order to more stably convert the conveying direction of a heavy-weight large-size glass plate, a balanced level state is integrally kept by uniformly dispersingpower in the ascending / descending action process of an upper stand provided with trip rollers in an arraying way so that partial subsidence is not generated, therefore bad influence is ensured not tobe caused on the glass plate and the quality of processed products is also enhanced when the direction of the large-size glass plate is converted.

Description

technical field [0001] The present invention relates to a technique of direction changing device of a glass plate manufacturing engineering conveying line for a liquid crystal display device. In more detail, it relates to a pneumatic spiral steering type conveying that can more stably change the transfer direction of a glass plate with a large weight and a large specification. machine. Background technique [0002] Generally speaking, the glass plate steering device can be divided into the following methods: the glass plate transferred to the workbench runs according to the running direction or is transferred according to the vertical direction; Direction operation, or the steering method of moving in the desired direction after rotating in situ; [0003] Among these turning devices, if you look carefully at the turning device of the rotating glass plate, there are a plurality of rotating shafts arranged in parallel at a certain interval, and a roller transfer machine with ...

Problems solved by technology

[0010] In other words, as the specifications of flat-panel display devices increase in size, in order to reliably transfer and process large glass plates, and to accommodate large-size glass plates, it is necessary to increase the size of the steering gear; , when the upper frame moves up / down, due to the bending phenomenon of the upper frame, it will cause adverse effects on the transferred glass plate

[0011] That is to say, when the upper frame rises through the upper / lower cylinder installed in the central part, the pressure acts on the central part concentratedly, which will cause the peripheral sinking phenomenon

[0012] At the same time, when transferring large-sized glass plates, the discharge rollers arranged on the upper frame should form a uniform plane at the same height, while the central part is high and the surroundings are in a state of sinking, forming an imbalance that will give the glass plates cause adverse effects
