Description

Technical Field

The invention relates to the technical field of cold end conveying on an automobile glass production line, in particular to a three-dimensional conveying roller way mainly used for conveying glass.

Background

The automobile glass production line has the characteristics of high conveying speed, small glass specification and short glass period. Therefore, in order to ensure the smoothness of the main channel, generally, the glass is not grabbed on the main line conveying roller way, but the glass is transferred to the branch line conveying roller way perpendicular to the main line conveying roller way to be grabbed.

The traditional method for conveying the branch line conveying roller way to the branch line conveying roller way in a steering way has two types, one is a common domestic overpass roller way conveying method, and the other is a double-layer roller way conveying method which is frequently used abroad.

In the double-layer roller way conveying method, a long section of conveying roller way is needed to be swung downwards for a certain angle and then directly connected to a lower roller way for steering conveying. The method has no obvious advantages in period, and the swing roller way is too large, so that the structural stability is poor.

When the glass plate conveying device works, before the glass plates reach the three-dimensional conveying roller way, the control system informs the three-dimensional conveying roller way that the group of glass plates are conveyed to a main line or a branch line through the three-dimensional conveying roller way. If the glass plate needs to be conveyed to the main line, the glass plate selecting roller way 1 keeps the horizontal direction and conveys the glass plate to the main line together with the hanging roller way 2. If the glass plate is required to be conveyed to the branch line, after the glass plate is conveyed to the setting position of the sheet selecting roller way 1, the air cylinder push rod mechanism 1.3 drives the sheet selecting roller way 1 to swing down for a certain angle, the glass plate swings down along with the glass plate, and at the moment, the lifting roller ways 4.2 of the receiving roller way 3 and the steering roller way 4 all operate at the same linear velocity as the sheet selecting roller way 1 to wait for the arrival of the glass plate. The glass plate is conveyed by the receiving roller way 3, when the glass plate reaches the designated position of the lifting roller way 4.2 of the steering roller way 4, the lifting roller way 4.2 stops running, the glass plate descends below the roller surface of the fixed roller way 4.3, the glass plate on the lifting roller way 4.2 is supported by the fixed roller way 4.3, then the fixed roller way 4.3 starts running, the glass plate is conveyed out along the direction vertical to the direction entering the steering roller way 4, after the glass plate leaves the fixed roller way 4.3, the lifting roller way 4.2 is lifted and runs again, and the next group of glass plate is waited to enter.

The invention has the beneficial effects that:

1. the swing angle of the sheet selecting roller way is small, and the glass is stably laid down without scratching or crushing; the length of the sheet selecting roller way is short, the lifting stroke is short, the time required by glass passing is short, and the requirement of safe passing of the automobile glass with a short period is met.

2. Hang the first conveying roller of roll table and adopt full vulcanite roller, this kind of material can accomplish the roller core when the same with other rollers, the roller external diameter is less, for meeting the roll table tip and letting out the top space, can not bump with hanging the roll table when guaranteeing glass to meeting the roll table transport. The materials of the driving bevel gear and the driven bevel gear have self-lubricating function, and the noise is low at high speed.

3. The inclination angle of each section of the roller way of the receiving roller way is slightly and progressively reduced, so that the adverse effect on glass conveying is avoided, the included angle between the third section of the receiving roller way and the lifting roller way is smaller, the energy decomposition in the vertical direction is smaller when glass enters the lifting roller way, and the damage of the glass to a belt is effectively avoided.

4. The lifting mechanism is simple and reliable, the stroke control is accurate, and the lifting period is accurate. The upper surface of the lifted belt is slightly lower than the lowest point of the roller surface of the third section of the receiving roller way, the design enables the actual contact point of the front edge of the glass and the belt to move backwards, and impact force generated when the front edge of the glass contacts the belt is reduced by means of the elasticity of the glass and the belt, so that the phenomenon that the glass gnaws the belt is effectively prevented, and the service life of the belt is prolonged.

5. The three-dimensional conveying roller way occupies a short time in the whole glass conveying process, and as long as the rear edge of the glass is separated from the sheet selecting roller way, the sheet selecting roller way can lift up the following glass to convey the glass to the main line conveying roller way. On an automobile glass production line, a plurality of sets of the three-dimensional conveying roller ways can be arranged on a main line conveying roller way, so that glass is conveyed to different branch line conveying roller ways according to a preset destination, and the automobile glass conveying with high speed, small specification and short period is realized.
