Definitions

  • the invention relates to a device having the features specified in the preamble of claim 1. Such a device is disclosed in DE 298 19 320 U1.
  • Glass panels are cut by scratching and breaking.
  • the glass sheets obtained in this way have sharp-edged, irregularly jagged craters, impurities, breaks and hairline cracks on the glass edge.
  • This is disadvantageous for various reasons: When handling without protective gloves there is a risk of injury; during transport of the glass sheet on one of its edges, in particular in an assembly line for insulating glass, in which the glass sheets are transported standing on one of its edges, the edges cause a special wear of the conveyor; Tools that run along the glass edge, such as sealing nozzles for the sealing of insulating glass, run irregularly and are also subject to one special wear; From the hairline cracks on the edge of the glass later, further stress cracks can develop in the glass panel and, for example, make an insulating glass pane unusable.
  • the known from DE 298 19 320 U1 device has a frame to which a support wall is fixed for a glass sheet to be processed.
  • the supporting wall can be designed as an air cushion wall, as a roller field or as a roller field, as known from assembly lines for insulating glass.
  • a horizontal conveyor is provided, on which the glass panels to be conveyed are set up with one of their edges.
  • the support wall is inclined a little backwards, so that the glass sheet can be transported leaning against it.
  • a driving device is provided, for example, a sucker, which can act on the glass sheet and is driven reciprocally.
  • each grinding head has two crosswise arranged, endless abrasive belts, which are guided over pairs of rollers, thereby being tensioned by an inner pressure medium cylinder and can be delivered by a further pressure medium cylinder against the glass edges, which create the tensioned abrasive belts on the glass edges and each grind a chamfer.
  • Grinding belt additionally provided a support roller, which supports the abrasive belt in the area which is intended for application to the glass edge, back.
  • the known from DE-U-298 19 320 U1 device has disadvantages:
  • the construction of the grinding heads is complex.
  • the abrasive belts these can not be arranged opposite each other, but only side by side, with a distance between them. This has the consequence that in the vicinity of the corners of the glass panels always only one of the sanding belts rests on the glass sheet edge, whereby the glass sheet loaded on one side and as a result is ground unevenly.
  • Another disadvantage is that with the abrasive belts no high accuracy is achieved, but the edge remains irregular. Irregularities that have a scratched and broken glass edge can be mitigated with abrasive belts, but difficult to eliminate.
  • the abrasive belts are subject to rapid wear. They have to be changed practically every day, which is time-consuming and leads to expensive machine downtimes. Due to progressive wear, the grinding effect soon decreases, which reduces the quality of the grinding result. This can be countered by an increase in the rotational speed of the grinding belt and by an increased clamping of the grinding belt, but only at the price of accelerated wear.
  • the present invention has for its object to provide a way how a generic device can be improved so that it achieves a better grinding result with less effort when trimming glass panels.
  • each of the grinding heads are provided as grinding tools instead of abrasive belts grinding wheels, in particular cup wheels, the axes of rotation in each of the grinding heads lie in mutually parallel planes whose distance is smaller than the diameter of the grinding wheels and which the direction of relative movement between the respective grinding head and the Cut the glass sheet at right angles while grinding.
  • grinding wheels simplifies the construction of the grinding heads. Pulleys, support rollers and tensioning devices for abrasive belts are no longer needed, the space required for the grinding tools is smaller and the grinding heads are lighter. Unlike grinding belts, the grinding wheels in the respective grinding head can be arranged overlapping each other or even exactly opposite one another (claim 4), whereby one-sided loads on the glass sheets and resulting, acting on the glass sheets torques are reduced or even made to zero. In addition, because of their rigid construction, unlike abrasive belts, the abrasive wheels do not tend to be deflected by glass panel irregularities. As a result, the edges of the glass sheets according to the invention are ground much more precisely than with the known belt grinders.
  • the distance between the two planes, in which the axes of rotation of the grinding wheels lie in the respective grinding head is expediently limited to the length at which the glass edge touches the grinding wheel when the device is used as intended.
  • this limitation of the distance not only the two grinding wheels of a grinding head, but also the areas in which they simultaneously act on the glass edge overlap. This leads to a correspondingly large reduction of one-sided loads on the glass edges, which even at the latest when the two planes coincide, are completely compensated because the two grinding wheels are then exactly opposite each other.
  • the grinding wheels can be placed on the glass edges in such a way that they act on the glass edge with a region close to the outer edge (close to the peripheral edge), only slightly beyond the edge protrude the glass board and do not interfere with each other.
  • the distance between the two planes, in which the axes of rotation of the grinding wheels lie preferably adjustable, at least by adjusting one of the two grinding wheels.
  • the distance between the two planes it is possible to change the degree of overlap when changing the thickness of the glass sheets to be ground. Since with thicker glass panels, the supernatant of the grinding wheels can be larger over the edge of the glass sheets until the two grinding wheels interfere with each other, as with thinner glass panels, with larger glass panels, a substantial overlap of the grinding wheels is easier than with thin glass panels.
  • the grinding wheels always hit the glass edges with the same section near their outer edge, then the grinding wheels only wear out there. It is more favorable to change the area of the grinding surface with which the grinding wheels act on the glass edges from time to time, so that the grinding wheels wear evenly over a larger area. This not only increases the service life of the grinding wheels but also prevents them from forming steps due to the grinding of glass plates of different thicknesses in the grinding surface of the grinding wheels, which subsequently can be reflected in the ground glass edges. Therefore, it is preferably provided that at least one of the grinding wheels of each grinding head, preferably both grinding wheels, transverse to the direction of relative movement, which occurs during grinding between the respective grinding head and the glass sheet, is parallel to itself or displaceable.
  • the two grinding wheels preferably have in common with their drives together with their drives, suitable adjusting members can be provided, for example spindle drives or with rack and pinion or working with a pressure medium cylinder adjustment. It is preferred that the adjusting members are arranged so that they can move the respective adjustable grinding wheel at right angles to the running plane of the glass sheets.
  • the plane of the glass sheets is understood to mean the plane in which the glass sheets move as intended when they are conveyed; the running plane is determined by the position of the horizontal conveyor and the driving device for the glass panels driven synchronously with it, as well as by the position of the supporting device for the glass panels arranged above the horizontal conveyor.
  • the grinding wheel lying substantially in front of the running plane of the glass panels is displaceable in each of the grinding heads, because the running plane of the glass panels is fixed and with it the plane in which the back of the glass panels located.
  • the grinding wheel which is intended for the grinding of the rear edge of the glass, therefore, can basically assume a constant position with respect to the running plane of the glass sheets, whereas it is expedient to change the front grinding wheel to adapt to differently thick glass sheets in their distance from the running plane of the glass sheets , Because the front Abrasive disk, however, due to its inclination, can partly grip behind the running plane, it has been stated above that it lies "substantially" in front of the running plane of the glass sheets.
  • the grinding wheels are individually displaceable in their flat grinding surface. This makes it possible in a simple manner to retract a first of the two grinding wheels so far behind the edge of the glass sheet to be processed in each grinding head that the second grinding wheel, when it is advanced over the edge of the glass sheet, can no longer hit the first grinding wheel , This makes it possible for the second grinding wheel to use a region lying further away from its outer edge for grinding, while in the first grinding wheel a section lying closer to its outer edge is used for grinding. By varying these distances and by interchanging their positions with respect to the glass sheet edge, it can be achieved in this way that both grinding wheels wear evenly on the majority of their grinding surface or even on the entire grinding surface.
  • the grinding process requires a certain pressure of the grinding wheels on the glass sheet edge. So that this is maintained even with existing irregularities of the glass panel edge, means for resilient Andrükken the grinding wheels are preferably provided on the glass panel edge. It may be coil springs, rubber springs or other elastomeric springs, pressure cylinder or combinations of these, which are stretched during the delivery of the grinding heads against the glass panel edge or the delivery of the glass panels against the respective grinding head. The grinding wheels can then respond with some compliance to irregularities in the glass sheet edge, eg protruding tips.
  • the grinding wheels are preferably with a damping device connected, via which they can be pressed against the edge of the glass panels.
  • the damping devices can be conventional vibration absorbers based on pressure-medium cylinders, optionally in combination with damping springs.
  • At least one intended for application to the edge of the glass sheet roll is preferably provided on the grinding head, which is arranged precedently with respect to the relative movement between the grinding wheels and the glass sheet grinding wheels and can roll on the edge of the glass sheet.
  • the course of the edge of the glass sheet can be scanned and the grinding wheels are tracked accordingly.
  • This is favorable for a good abutment of the grinding wheels on the glass sheet edge, both in view of randomly occurring irregularities of the glass sheet edge and in glass sheets having a shape deviating from the rectangular shape, so-called model disks, which are e.g. have an arcuate edge portion.
  • Particularly reliable is the leadership of the grinding wheels along the glass panel edge when the grinding head has not only one role, but two rollers which scan the glass panel edge, one roller ahead of the grinding wheels and the other role of the grinding wheels to be trailing.
  • these roles can take on another task, namely to limit the travel, and thus limit the pressure force when the grinding wheels create by advancing the grinding head against the glass sheet edge or by advancing the glass sheet against the grinding head to the glass panel edge and the means be stretched to the resilient pressing of the grinding wheels.
  • the spring travel is terminated and the tension and thus the contact pressure of the grinding wheels are limited to the glass panel edge.
  • At least one of the grinding heads is rotatable about an axis extending at right angles to the running plane of the glass sheets, which expediently passes through the grinding surfaces of the two grinding wheels in that region with which the grinding wheels are to act on the glass edges.
  • the control signals to be able to track the grinding head by motor to the edge of the glass panels. You can win using the tactile rollers or specify the device by a control program that knows the shape and dimensions of the glass panels to be processed and provides for the controller.
  • the device shown in Figure 1 is a machine for trimming the edges of glass panels and is intended primarily for installation in an assembly line for insulating glass panes.
  • the apparatus has a frame 1, which carries a horizontal conveyor 2, which consists in the present case of a row of synchronously driven rollers with approximately horizontal axis of rotation on which glass sheets 3 can be transported standing and leaned against a support means 4 through the device, namely in Figure 1, for example, from right to left.
  • a horizontal conveyor 2 which consists in the present case of a row of synchronously driven rollers with approximately horizontal axis of rotation on which glass sheets 3 can be transported standing and leaned against a support means 4 through the device, namely in Figure 1, for example, from right to left.
  • further stations of the insulating glass assembly line would join on both sides of the device, each having a horizontal conveyor of equal height and also a support device to which the glass sheets 3 can lean.
