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 technology for manufacturing a direction converting device of a construction conveying line using glass plates for liquid crystal display devices. In more detail, it relates to a pneumatic helical steering type conveying device that can more stably change the conveying direction of large-weight and large-sized glass plates. machine. Background technique [0002] Generally speaking, the glass plate turning device can be divided into the following ways: the glass plate transferred to the worktable is run in the running direction or the transfer mode is changed in the vertical direction; the glass plate transferred to the worktable is moved according to the running direction. Orientation, or a steering method that moves in the desired direction after rotating in place; [0003] Among these steering devices, carefully observe the steering device of the rotating glass plate, there are a plurality of rotating shafts arrang...

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
