BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a device with the features of the introductory part of claim 1.
In the flat glass industry the problem often arises of transporting glass plates, for which among others transport rollers, conveyor rolls, and continuous conveyor belts are used, on which the glass plates rest. Conveyor belts are provided for example also in glass cutting tables, often there being several conveyor belts which are admitted into the plate of the glass cutting table and which extend parallel to one another.
Since float glass is coated with a lubricant for reasons of manufacture, it is not easy to transfer the delay and acceleration forces which occur during transport of glass plates from the conveyor belt or conveyor belts to the glass plates. This leads to the conveyor belts sliding through at the start of a conveyor process, therefore when the glass plates accelerate, and to the glass plate not being braked quickly enough and stopped precisely at the end of the conveyor process so that it can happen that it slips against the system parts and damages them and/or is itself damaged.
DESCRIPTION OF THE RELATED ART
It has already been proposed that the conveyor belts which engage the glass plates be cleaned, an approach which however has not achieved the objective, since the surfaces of the conveyor belts which are made rough or otherwise to increase friction cannot be effectively cleaned and a host of conveyor belts is affected.
Removing the lubricant from the glass plates on their side facing the conveying means using a brush roller which turns around an axis which extends transversely to the transport direction is also known. In this case the removed lubricant is however uncontrollably swirled by the brush. In particular, when the rear edge of the glass plate moves over the brush roller, the aforementioned swirling of the lubricant occurs to an especially pronounced degree, since the brush roller is then no longer completely covered by the glass plate.
SUMMARY OF THE INVENTION
The object of the invention is to devise a conveying device for glass plates which solves the aforementioned problems and which ensures reliable friction between the glass plate and the conveyor belt.
According to the invention this object is achieved with the features of the characterizing part of independent claim 1.
Preferred and advantageous embodiments of the device according to the invention are the subject matter of the subclaims.
BRIEF DESCRIPTION OF THE DRAWINGS
Other details and advantages of the invention follow from the following description of one embodiment of the invention in which reference is made to the drawings.
FIG. 1 schematically shows in an oblique view a glass plate conveyor device,
FIG. 2 shows in a side view a cleaning brush in the form of a conventional belt brush,
FIGS. 3 and 4 show embodiments with several brushes in an overhead view.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The conveyor device shown in FIG. 1 for glass plate 10 is integrated for example in a glass cutting table and consists of support surface 20 for the glass plate 10, in support surface 20 there being several continuous conveyor belts 25 (only suggested in FIG. 1) which run parallel to one another and which can optionally be lowered under the upper surface of support surface 20.
The strands of conveyor belts 25, strands which are provided in support surface 20, move here in the direction of arrows 26, i.e., in the same direction as glass plate 10 is delivered (arrow 11). Glass plate 10 was for example removed using a crane-like means from a glass bed, laid flat using a tilt table, and moved immediately from the latter to glass cutting table 20.
In front of edge 24 of support surface 20 of the glass cutting table, the edge which is forward viewed in the conveyor direction (arrow 11) there is belt brush 30 which has continuous brush belt 35 which carries brushes which point to the outside and which are attached to a continuous carrier, and which moves in the direction of arrows 36.
