Definitions
- the invention relates to a device with in the preamble of claim 1 specified characteristics. Such a device is described in DE 298 19 320 U1 disclosed.
- Glass panels are cut by scratching and breaking.
- the thus obtained Glass panels have sharp-edged, irregularly jagged craters, wraps, Breakouts and hairline cracks on the glass edge.
- the device known from DE 298 19 320 U1 has a frame on which a Supporting wall is attached to a glass panel to be processed.
- the supporting wall can as an air cushion wall, as a roller field or as a roller field, as from assembly lines for insulating glass known to be formed.
- a horizontal conveyor In the area of the lower edge of the Supporting wall is provided a horizontal conveyor, on which the promotional Glass panels are set up with one of their edges.
- the supporting wall is a little bit tilted backwards, so that the glass sheet are transported leaning against it can.
- a driving device provided, e.g. a sucker, which can act on the glass sheet and hinund is driven drivable.
- each grinding head has two crosswise arranged, endless sanding belts, which are guided over pairs of rollers, here an internal pressure medium cylinder are tensioned and by another Pressure medium cylinder can be delivered against the glass edges, whereby the tensioned sanding belts attach themselves to the glass edges and in each case grind a chamfer.
- Sanding belt additionally provided a support roller, which the sanding belt in the area intended for application to the glass edge, on the back supported.
- the known from DE-U-298 19 320 U1 device has disadvantages:
- the structure The grinding heads are complex.
- the abrasive belts can not be arranged opposite each other but only next to each other, with a gap between them.
- the As a result, near the corners of the glass panels is always only one of the Abrasive belts on the glass panel edge is applied, whereby the glass panel loaded on one side and as a result thereof is ground unevenly.
- Another disadvantage is in that with the abrasive belts no high accuracy is achieved, but the edge remains irregular. Irregularities a scratched and broken Glass panel edge, although can mitigate with abrasive belts, but difficult to eliminate.
- the grinding wheels are subject to a rapid 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.
- grinding wheels in particular cup wheels, provided, whose Rotary axes 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 the relative movement between the respective grinding head and cut the glass sheet at right angles during grinding.
- the use of grinding wheels simplifies the Structure of the grinding heads. Pulleys, support rollers and clamping devices for Abrasive belts are no replacement, the space required for the grinding tools is smaller, the grinding heads become lighter. Unlike sanding belts, the Grinding wheels in the respective grinding head overlap each other or even each other exactly opposite (claim 4) are arranged, whereby one-sided Strain on the glass panels and resulting, attacking on the glass panels Torques are reduced or even made to zero. Furthermore Due to their stiff construction, the grinding wheels tend to be contrary to Abrasive belts are not, distracted by irregularities of the glass panel edge to become. As a result, the edges of the glass sheets become according to the invention much more precisely ground 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 on which the glass edge under normal use of the device the grinding wheel touches. Due to this limitation of the distance not only the two grinding wheels of a grinding head overlap, but also also the areas in which they act simultaneously on the glass edge. This leads to a correspondingly large reduction of one-sided loads the glass edges, which even at the latest when the two planes coincide, be completely balanced because the two grinding wheels then lie exactly opposite each other.
- the grinding wheels so on the Glaskanten can be delivered, that they with a close to the outside Edge (near the peripheral edge) area acting on the glass edge, only slightly above the edge of the glass panel protrude and not hinder each other.
- the distance between the two levels, in which the axes of rotation of the grinding wheels lie preferably adjustable, at least by adjusting one of the two grinding wheels. By the adjustment of the distance of the two levels, it is also possible, the degree the overlap when changing the thickness of the glass sheets to be ground.
- the supernatant of the grinding wheels over the edge of the Glass panels can be larger until the two grinding wheels obstruct each other, as with thinner glass panels, with larger glass panels is a far-reaching Overlapping of the grinding wheels easier possible than thin glass plates.
- the two grinding wheels to the grinding head together with their drives preferably have in common, suitable adjustment can be provided be, e.g. Spindle drives or with rack and pinion or with a pressure medium cylinder working adjusting organs. It is preferred that the adjustment so are arranged that they the respective adjustable grinding wheel in the right Can move angles to the running plane of the glass panels.
- suitable adjustment can be provided be, e.g. Spindle drives or with rack and pinion or with a pressure medium cylinder working adjusting organs. It is preferred that the adjustment so are arranged that they the respective adjustable grinding wheel in the right Can move angles to the running plane of the glass panels.
- glass sheets are understood to be those in which which the glass panels move as intended, when they are promoted become; the level is determined by the position of the horizontal conveyor and the synchronously driven with him takeaway device for the glass panels as well as by the location of the above the horizontal conveyor arranged support means for the glass panels.
- each of the Grinding heads at least substantially in front of the running plane of the glass sheets lying grinding wheel is slidable, because the running plane of the glass panels fixed is given and with it the plane in which the back of the Glass panels is located.
- the grinding wheel which is used for grinding the back Glass edge is provided, therefore, basically a constant position with respect to the running plane of the glass panels, whereas it is convenient is, the front grinding wheel to adapt to different thickness glass sheets to change in their distance from the running plane of the glass panels. Because the front Grinding wheel due to its inclination but partly behind the running plane It has been stated above that they are "essentially" in front of the run level the glass panels lies.
- the grinding wheels individually in their planes Sliding surface are displaced. That makes it possible in a simple way, at each grinding head a first of the two grinding wheels far behind the Retract the edge of the glass sheet to be machined so that the second grinding wheel, if it is pushed over the edge of the glass panel, nothing more can hit the first grinding wheel. That makes it possible at the second Grinding wheel one from its outer edge further away area for use the grinding, while at the first grinding wheel a closer at its outer edge lying portion is used for grinding.
- Varying these distances and swapping their positions with respect to the Glasstafelrandes can be achieved in this way that both grinding wheels on most of their grinding surface or even on the whole Wear evenly on the grinding surface.
- the grinding process requires a certain pressure of the grinding wheels to the Glass panel edge. So that this even with existing irregularities of the Glass panel edge remains, are preferably means for resilient Andrükken the grinding wheels provided on the glass sheet edge. It can work around coil springs, rubber springs or other elastomeric springs, pressure cylinder or combinations of these, which upon delivery of the Grinding heads against the edge of the glass panel or during the delivery of the glass panels against be clamped the respective grinding head. The grinding wheels can then with a degree of compliance to irregularities in the glass panel edge, e.g. on protruding tips, react.
- 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 may be conventional vibration dampers on the basis of pressure cylinders, if necessary in combination with damping springs, act.
- At least one is preferably at the grinding head for application to the Edge of the glass sheet certain role provided, which with respect to the relative movement between the grinding wheels and the glass sheet the grinding wheels is arranged ahead and can roll on the edge of the glass sheet.
- the grinding wheels In order to The course of the edge of the glass panel can be scanned and the grinding wheels be tracked accordingly. That's for a good plant of grinding wheels cheap on the glass panel, both in terms of random occurring irregularities of the glass panel edge as well as glass panels, which have a different shape from the rectangular shape, so-called Model disks, which are e.g. have an arcuate edge portion.
- Particularly reliable is the guidance of the grinding wheels along the Glass panel edge, if the grinding head not only one roll, but two rolls has, which scan the glass panel edge, with a roller grinding wheels leading and the other role the grinding wheels trailing arranged should be.
- these roles can take on another task, namely the Limit travel, and thus limit the contact force when the Grinding wheels by feeding the grinding head against the glass sheet edge or by placing the glass sheet against the sanding head against the glass sheet edge and thereby stretched the means for resiliently pressing the grinding wheels become. If the rollers hit the glass panel edge, the travel is completed and the tension and thus the pressure of the grinding wheels to the glass panel edge limited.
- At least one of the grinding heads is a right angle to the running plane of the glass sheets extending axis is rotatable, which the Abrasive surfaces of the two grinding wheels expediently in that area interspersed, with which the grinding wheels are to act on the glass edges.
- the device shown in Figure 1 is a machine for trimming the edges of glass panels and is primarily for installation in an assembly line intended for insulating glass panes.

- FIG. 2 shows a View of the first grinding head 5 in the station 1 of the illustrated in Figure 1 Device, but with respect to the Figure 1 reverse conveying direction.
- the grinding head 5 has a carrier 20 for two crosswise arranged grinding wheels 21 and 22 and for the electric motors driving them 23.
- the axes of rotation 24 and 25 lie in two mutually parallel planes, which in the right Angle to the direction of the relative movement between the grinding head 5 and the glass sheets 3 runs, that is perpendicular to the grinding head 5 in the present case to the longitudinal direction of the vertical guides 10.
- the carrier 20 is rotatable in one Bearing 26 mounted, which in turn guided by four vertical guides 10 is.
- the frame 26 carries bearings 27 for the rotatable mounting of the carrier 20 and a drive 28, which is the rotation of the carrier 20 about a vertical to the running plane of the glass sheets 3 extending axis 29 causes.
- spindle drives 30 are the two grinding wheels designed as cup wheels 21 and 22 together with their electric motors 23 at right angles to Running plane of the glass panels 3, ie parallel to the axis of rotation 29, displaced and allow thereby adapting to differently thick glass panels 3. Zur Control of the spindle travel is the spindles 30 each a potentiometer 37th assigned.
- Spring and damping devices 31 are arranged, which are parallel extend to the running plane of the glass sheets 3 and a combination of springs with represent a damping cylinder, like a conventional vibration damper can be constructed. They ensure a sufficiently even, resilient pressure of the grinding wheels 21 and 22 to be machined Glass edges.
- the two ends of four toothed belts 32 are fixed, which are each guided via gears 33 and 34, one of which is below and one is mounted in the top of the housing 15. From the gears 33 and 34 in each case at least one is driven.
- the synchronization of the gears 33 and 34 can be electric or mechanically, e.g. with the help of them connecting rods 38.
- two rollers 35 and 36 are still provided, which are mounted on the carrier 20 free-running and one of which the grinding wheels 21 and 22 leading and one the grinding wheels 21 and 22nd trailing arranged. These rollers 35 and 36 touch the edge of the glass panels 3 and also limit the travel of the spring and damping devices 31 when delivering the glass sheets 3 against the grinding wheels 21st and 22.
- a running into the device glass sheet 3 is in the station 1 against the Driven grinding wheels of the local first grinding head 5 and by stopping of the horizontal conveyor 2 and the belt straps 11 held.
- the Grinding wheels 21 and 22 have resiliently against the front edge of the glass sheet 3 created and move up to this, passing through the engines 23 and 24 are driven.
- the front upper Ekke the glass panel 3 has left behind, he is stopped and the glass panel 3 moved into the station 2 and fixed there as soon as the front edge of the Has reached the effective range of the grinding heads 6 and 7, which the lower Edge and the top of the glass sheet 3 are resiliently applied. Is that done the glass sheet 3 is transported further in the conveying direction 9, wherein the upper edge and the lower edge are trimmed.
- the grinding head 7 is pivotable, it can move in a corresponding manner as in FIG. 6 be used to trimming a model disk, the e.g. an arcuate upper edge has.
- the grinding head 7 of the grinding head 5 by 180 ° pivotable, then it can also be worked as shown in Figure 7 is: In the station 1 is first held glass plate 3 whose front Edged edge with the grinding head 5. Then the grinding head 5 against the curved arcuate upper edge and this by forward feeding the Glass panel 3 edited. If the upper rear corner of the glass panel 3 reaches the attack area the grinding wheels, then the glass sheet is stopped again and when glass plate 3 is held, the grinding head 5 against the rear edge the glass sheet 3 is pivoted and moved along this down.
- Station II the glass panel is promoted to Station II and the Grinding head 5 pivoted to its original position. Edited in Station II the stationary grinding head 6, the glass sheet 3 in the pass. Station III is only a transit station without special function.
- the rollers 35 and 36 see FIGS. 3 and 5, when machining model disks, can help the grinding head 8 optimally along the arcuate edge to lead.
- Figure 8 shows a variant in which the device only two stations and only has two grinding heads, namely a first station with an up and retractable and swivelable by 180 ° grinding head 7 and a second station with a movable up and down and at least 90 ° Grinding head 6.
- a first station with an up and retractable and swivelable by 180 ° grinding head 7
- a second station with a movable up and down and at least 90 ° Grinding head 6.
- the first station is first at resting glass panel 3 whose front edge ground by the grinding head 7. Achieved the grinding head 7 the Front upper corner of the glass panel 3, it is rotated by 90 ° and then grinds the upper edge while the glass sheet 3 passes the grinding head 7 becomes.
- the rear upper corner reaches the grinding head 7, the glass sheet 3 is stopped and the grinding head 7 moves at the rear edge of the glass sheet 3 down.
- the glass sheet 3 is conveyed to the second station and there ground by means of the grinding head 6 of the lower edge in the run until the Rear lower corner reaches the grinding head 6. Then the glass sheet 3 is stopped, the grinding head 6 is pivoted by 90 ° and then moves to the stationary Glass plate 3 upwards to grind its rear edge. In appropriate Way can be trimmed in such an arrangement, a model disk become.
- Rectangular glass panels and model disks can also be used in one device trimmed with only two stations, if this e.g. two grinding heads 6 and 7, of which one, namely the grinding head 7, up and abverfahrbar and is pivotable by 180 °, and of which the other grinding head 6 is stationary and only serves to grind the lower edge of the glass sheet 3, as in Figure 9 is shown in the successive phases 1 to 5.
- FIG. 10 schematically shows a possibility of the two grinding wheels 21 and 22 to position on the edge of the glass sheet 3, and that substantially symmetrical to the glass sheet 3.
- Figure 11 shows another possibility, the grinding wheels 21 and 22 to be positioned on the glass sheet 3, namely so that the one grinding wheel 21 its grinding surface of the peripheral surface of the second grinding wheel 22nd turned toward.
- the two grinding wheels 21, 22 are individually displaceable parallel to their grinding surfaces. In this way can the grinding wheels 21 and 22 often different at the edge of the Glass panels 3 are positioned so that the wear of the grinding wheels spread over a larger area of their grinding surfaces.
