Description

Technical field

The present invention relates to the field of mechanical engineering, in particular to an edging machine for glass, in particular a horizontal linear edger with a grinding wheel or a grinding wheel for closing four sides of the glass.

Background of the technique

In order to enable a further processing after cutting a glass sheet, in particular a reworking the hard glass, laminated glass and insulating glass with intermediate cavity, the edges should be ground in almost all of these glass sheets before completion or before re-machining. The requirements and methods of grinding are different due to the different fields of application. Edge sanding can meet the various requirements for safety, protection for breakage, aesthetics, format, etc. Edge sanding can be divided into two types depending on the work processes, i. H. manual and machine grinding. Manual edge grinding refers to grinding or cutting off the glass with an edge sharpening device in the hand. This also includes holding the glass sheet in hand and grinding or cutting with the edger. The machine edge grinding is the processing of the glass pane, in which the glass sheet is transported by a conveyor in the edge grinding device. Depending on the shape of the glass pane, the edge grinding can be divided into linear and non-linear grinding. Linear edge grinding, for example, refers to the grinding of a rectangular glass sheet. According to the material used, the edge grinding can be divided into belt loops and wheel loops. Belt grinding often involves manual edge grinding.

The existing linear edging machines with grinding wheel are divided into two types, namely the vertical linear edging machine and the horizontal edging machine. With these two edge sanding machines, not all four edges of a rectangular glass can be machined in one operation. You can only grind one edge or side of the glass pane before repositioning the glass pane manually so that the other three sides can be processed. Such a device is off CN 200620085825 gets. In mass production, four of these devices are often required in succession to achieve high manufacturing efficiency. In addition, many workers are needed to transport the glass panes. This causes high equipment costs and at the same time requires a larger area of the factory. CN 2008201475703 While suggesting the use of NC equipment, it still can not process all four sides of the glass sheets at once.

Double-sided edge sanding provides improved machining in which it can sand the edges on two sides at the same time. However, it also can not grind edges on all four sides at the same time. In mass production, two systems are still needed side by side to achieve high production output. In addition, the system is set every time the machine tool is changed, which is expensive and time consuming. In addition, when the glass is transferred by pressing with a synchronized upper and lower conveyor belt, the glass shards that have been caused by grinding may damage the surface of the glass together with the conveyor belts, especially in a LOW-E coated glass that has a surface coating from z. B. silver is provided and thus energy-saving. This surface is relatively sensitive. Damage to the surface can lead to oxidation of the glass.
