Description

The invention relates to mechanical engineering for the glass industry and is intended for use in the production of technical and structural sheet glass:

The purpose of the invention is to increase conveyor productivity.

Due to the fact that the slot for the passage of sheets transported by the conveyor is formed under the transport beams by installing each of them on two racks mounted on the frame, the distance between which is greater than the width of the sheets, allows transporting sheets of a larger width than in the known device.

The reliability of the transport beams can be enhanced by the implementation of their working bodies in the form of drive disks. This reduces damage to the working bodies themselves by the side edges of the glass and damage to the sheets due to their deflection on the working bodies.

The invention is illustrated in the drawing.

The glass sheet roll-off device contains a haul-off device 1, which includes a lifting frame 2, transport beams 3 (the others are shown in the drawing) and the racks 4 and 5 connecting them, the lifting frame 2 may extend beyond the conveyor frame 6. In this case racks 5 may occupy position 7. Each transport beam 3 is provided with disks 8, which inform the movement of sheet 9. On the transport frame, some disks 10 may be idle. The frame 2 is located under the rollers 11 of the conveyor, transport beams between them. The basis for the rollback device 1 is the lifting mechanism 12 mounted on the base plate 13. The mechanism 12 shown in the drawing contains a driving crank 14, a connecting rod 15 and two shoulders levers 16 and 17 connected by a link 18 and pivotally mounted on the uprights 19 of the base plate 13, on a lifting frame 2 is mounted on the hinges of the levers 16 and 17, Sheet 20 is located on the rollers 11 of the conveyor. When rolling, the transport beams 3 are raised by a mechanism

lifting 12 to a height that provides a clearance between the rollers 11 and the lifting frame 2, as well as between the sheet 20 and the transport beams 3. For this, the height of the racks 4 and 5 should be selected by the ratio

h d + s

where d is the diameter of the rollers;

s is the thickness of the sheet.

The distance between the posts 5 and 4 is greater than the width of the sheets, which allows for the free transport of sheets by conveyor. The implementation of racks 4 and 5 of small thickness t allows processing sheets of nominal width for the conveyor.

In the initial position, the transport beams 3 are set by the lifting mechanism 12 to a lower position in which their upper surface is below the level of the working surface of the rollers 11.

The hauler operates as follows.

When the sheet approaches the lifting position with the hauler, the crank 14 is turned 180 ° from the connecting rod 15 and the levers 16 and 17. The hauling device 1 together with the sheet rises to the position shown in the drawing. Then, the disks 8 are driven into rotation and the sheet 9 is transferred to the processing chain. At this time, the sheets 20 following the conveyor are transported by rollers 11 under transport points 3 and between the posts 4 and

5. When the sheet 9 comes off the haul-off device 1 and there is a gap between the sheets under this device, the crank 14 transported by the conveyor is again rotated 180 °. lowering the haulage device to its original position.

Then the cycle of work is repeated.

Thus, the present invention allows for high productivity of the conveyor due to the use of its entire useful area. The serviceability of the hauler is improved since its working bodies are placed in one of the standard positions above the level of sheet transport. The reliability of the operation is also increased by reducing the possibility of damage to the working bodies of the hauler and sheets rolled by it.
