Description

METHOD AND CLAMPING DEVICE FOR FIXING ONE

PLATE-SHAPED OBJECT

The invention relates to a method for fixing a plate-shaped object, for example a glass pane, in a support plane, the plate-shaped object being fixed with a clamping device by at least one pressure element and at least one counter element of the

Clamping device can be placed on opposite sides of the plate-shaped object and the plate-shaped object is clamped between the pressure element and the counter element.

Furthermore, the invention relates to a clamping device for

Set one arranged in a support level

plate-shaped object and a cutting system for dividing a plate-shaped object, for example one

Glass pane.

In the course of processing glass panes in different

Processing devices, it is often necessary to fix glass panes with the aid of clamping devices, so that the glass panes are fixed to the processing device during processing or so that the glass panes, or at least parts of the

Glass panes that can be moved. Such clamping devices have, for example, adhesive elements (in particular suction heads for sucking firmly onto the glass pane) which adhere to the glass pane, so that the glass pane is fixed by the clamping device. Other clamps have two

holding elements movable towards each other, for example a pressure element and a counter element, between which the

Glass pane can be held and clamped. at

Clamping devices with two movable towards each other

Retaining elements are usually on surfaces of the holding elements, which when clamping the glass sheet with the surface of the

Glass pane come into contact, special coverings are provided. Depending on the glass pane to be processed, these coverings can have different properties.

On the one hand, when processing some glass panes, it can be advantageous if particularly non-slip coverings, for example made of rubber or polyurethane, are arranged on the holding elements, so that even a small clamping force is sufficient to fix the glass pane in the clamping device. On the other hand, when processing glass panes that are coated or specially treated on the surfaces, it is necessary to use particularly surface-friendly coverings, such as felt coverings, which largely avoid damaging the coating or changing the surface properties.

Clamping devices which have holding elements with special coverings are generally known. A disadvantage of known clamping devices is that the replacement of the pads can only be carried out manually and thus with the processing device at a standstill, and is therefore very time-consuming and

is labor intensive. When setting different types of glass panes - for example coated and

uncoated glass panes - with known clamping devices, increased downtimes must therefore be expected.

The invention is based on the object, a method of the type mentioned and one for this method

to provide suitable clamping devices which do not have the disadvantages of the prior art.

For example, the invention is intended to be a method

are provided with which different types of glass panes can be defined as simply and effectively as possible in chronological order. Furthermore, a clamping device that can be adapted quickly and easily, preferably automatically, to use with different types of glass panes and a cutting system that has at least one such clamping device are to be provided.

According to the invention, this object is achieved with a method having the features of claim 1

Clamping device having the features of claim 5 and with a cutting system having the features of claim 24.

Preferred and advantageous embodiments of the invention are the subject of the dependent claims.

According to the invention it is provided that in the method according to the invention a covering of at least two from one another

different coverings of the pressure element and / or the

Counter element is positioned in an active position assigned to the counter element or the pressure element, and that the covering positioned in the active position when the

plate-shaped object is applied to the plate-shaped object.

In the method according to the invention and in the

Clamping device according to the invention, the one covering of at least two different coverings is provided in its operative position on the pressure element or on the counter element or on the pressure element and on the counter element. Therefore, in the case of the invention, the respective (suitable) covering on the pressure element or on the object to be fixed, such as a glass pane

Counter element or be positioned on the pressure element and on the counter element in its operative position. Therefore, in the invention, one side or the other side of the

plate-shaped object or both sides the plate-shaped object (for example the

Glass pane) each touched by a suitable covering.

The labor-intensive and time-consuming dismantling of a covering and the fitting of another covering are therefore completely eliminated.

Within the scope of the invention, a covering is considered to be assigned to the counter element or the pressure element or positioned in the operative position if it is arranged on the pressure element and / or the counter element in such a way that that part of the pressure element which is approximated to the counter element (or vice versa) of

Pressure element and / or the counter element that the

Counter element or the pressure element is closest.

For example, the covering assigned to the counter element or the pressure element is when the plate-shaped is clamped

Object, for example the glass pane, that part of the pressure element or the counter element that on the

plate-shaped object rests, whereas the second covering is spaced from the plate-shaped object.

In a preferred embodiment of the method according to the invention, the is in the operative position before clamping

positioned covering against another covering if necessary

replaced by a carrier of the pressure element, on which the coverings are arranged next to one another, being displaced essentially parallel to the support plane. It is particularly advantageous that this embodiment with known, only

retrofitted clamping devices can be performed.

In a further preferred embodiment of the

The method according to the invention is, before clamping, the covering positioned in the active position, if necessary, replaced by another covering by the pressure element on its

at least two surfaces each one of the pads is arranged around an axis that is at an angle or substantially parallel runs to the support plane, is rotated. A particular advantage of this embodiment is that the pads only have to cover short distances when changing due to the rotary movement, so that the pads can be changed quickly with this embodiment.

In yet another preferred embodiment of the method according to the invention, the covering, which is positioned in the active position, is exchanged for another covering, if necessary, in that at least one of at least two holding means of the pressure element, on each of which one of the coverings is arranged, is essentially normal to the support plane is moved towards or away from this. Advantage of this

The embodiment is that changing the covering is not associated with any additional action, but is only effected by the selection and activation of the holding means with the appropriate covering, which is placed on the plate-shaped object.

A clamping device according to the invention for fixing a plate-shaped object arranged in a support plane, for example a glass pane, has at least one

Pressure element and at least one counter element, which are approachable to each other and the support plane, so that the plate-shaped object, for example the glass pane, between the

Pressure element and the counter element can be clamped.

According to the invention, it is provided that the pressure element has at least two mutually different coverings, one of which is optionally assigned to the counter element.

It is particularly advantageous in the clamping device according to the invention that its pressure element already has different coverings for holding different types of plate-shaped

Objects, for example glass panes. Thereby the pad can be changed quickly and easily, just by adjusting one or more parts of the pressure element.

It is particularly preferred if the part or parts of the printing element are remote-controlled, for example by operating personnel or automated, for example computer-aided

Clamping device can be assigned. This means that the surface can be changed without having to take any special safety precautions. Furthermore, another covering can be assigned to the counter element quickly and effectively, for example between work cycles of a processing device.

The clamping device according to the invention can be adjusted as a whole between a ready position and a fixed position. In the ready position, the pressure element and the counter element are spaced from one another, so that the

plate-shaped object, for example the glass pane, between the pressure element and the counter element in the

Support level can be positioned and moved (aligned). The pressure element and the are in the fixed position

Counter element approximated to each other, so that the pressure element abut on both sides of the plate-shaped object via a covering and preferably also via a covering and clamp the plate-shaped object, for example the glass pane.

Within the scope of the invention, the pressure element can have more than two coverings which can be assigned to the counter element, for example by adjusting one or more parts of the pressure element.

Such a clamping device according to the invention can

Capture three or more than three different types of plate-shaped objects, for example glass panes, can be used.

The clamping device according to the invention and the method according to the invention for clamping glass panes, for example laminated glass panes, are preferably provided. However, it is also conceivable that the clamping device in

To use processing devices with which other plate-shaped objects, such as metal plates or plastic plates, or also strip-shaped objects are processed or to use the method for fixing such other plate-shaped objects.

For example, a first is within the scope of the invention

Preferred embodiment, in which the pressure element

Has holding means with a surface facing the counter element and a carrier arranged on the surface, the coverings being arranged next to one another on the carrier. The carrier can be displaced on the holding means essentially parallel to the support plane in order to assign one of the coverings to the counter element. By moving the carrier, the other covering is arranged between the pressure element and the counter element and assigned to the counter element instead of the one covering. It is advantageous in this first embodiment that the coverings arranged on the carrier are particularly easy to clean and that the coverings are arranged on a separate carrier separate from the holding means. Conventional clamping devices can be converted quickly and easily to the clamping devices according to the invention.

In this embodiment, it is preferred if the carrier is a strip of flexible material. For example, the carrier can be a belt, for example a flat, wedge or

Toothed belt, or a textile belt, wherein the coverings are arranged on a side of the carrier pointing away from the holding means. The carrier can be, for example, a self-contained one

Be an (endless) carrier which is guided around the holding means via rollers which are arranged in the region of the holding means.

It is also taken into consideration that one end of the carrier is fixed to a roll on both sides of the holding means and the carrier can alternately be rolled up onto the roll or unrolled from the roll. In comparison to a carrier made of a rigid material, for example a strip, a large number of coverings can be arranged on such a flexible carrier without having to have a lot of space available on the side of the holding means.

In the context of the invention, the carrier can also be guided over drums or rollers or can be rolled up onto or off these. Furthermore, in the context of the invention, for example in the case of a closed (endless) carrier, a tensioning roller

be provided, which rests on the carrier and via which the voltage of the carrier can be changed.

There is preferably at least one in the region of the carrier

Cleaning device arranged so that at least one of the coverings can be moved past the cleaning device when the carrier is moved. For example, there are two

Cleaning devices are provided, one of which is arranged next to the holding means, so that pads are cleaned with each change of position and pad.

In the context of the invention, a further embodiment of the clamping device is preferred, in which the pressure element has at least two surfaces, on each of which one of the linings is arranged, the pressure element being rotatable about an axis in order to assign one of the linings to the counter element. Within the scope of the invention, the pressure element can have two, three, four or more than four surfaces and the axis can

Run essentially parallel to the contact surface or to

Support surface must be inclined at an angle. Such a pressure element takes up little space on the side and can extend over the entire width of the plate-shaped object, for example the glass pane, or only over part of the width of the

Extend object.

In this embodiment, the pressure element preferably has the shape of a straight prism with a polygonal,

for example a three, four, five or more than

pentagonal, footprint (cross-sectional shape).

The pressure element can, for example, be elongated and

be designed bar-shaped, so that the plate-shaped

Object can be clamped along its entire width, or can be made short, so that the plate-shaped object can only be clamped in certain, selected areas.

The surfaces on which the coverings are arranged enclose angles with one another, the angles between adjacent surfaces preferably being of the same size, so that the base surface of the pressure element has the shape of a regular polygon. The axis about which the pressure element is rotatable is normal to the base of the embodiment

Pressure element, for example essentially aligned parallel to the support plane.

A further development of this embodiment is also possible within the scope of the invention, in which the pressure element is a

circular base and thus has the shape of a cylinder or a roller. The surfaces on which the coverings

are arranged in this case are surface sections that directly adjoin one another. In a further variant of this embodiment, the pressure element has an essentially pyramid-shaped head with a polygonal, in particular a triangular, quadrangular, pentagonal or more than pentagonal, base area. The head points towards the counter element and the axis around which the

Pressure element is rotatable, preferably runs normally on the base of the pyramid-shaped head and includes an acute angle with the support plane. By turning the

One of the surfaces, which are the side surfaces of the pyramid and on which the coverings are arranged, can be aligned parallel to the support plane, so that the cover of this surface is aligned with the counter element

assigned.

A further development of this embodiment is also conceivable within the scope of the invention, in which the head of the pressure element has a circular base area and thus a conical shape. In this variant, too, the surfaces on which the coverings are arranged are surface sections which directly adjoin one another.

In one embodiment, at least one adhesive element, for example a

Suction element for sucking firmly on the plate-shaped object, in particular the glass pane. Additionally or instead, at least one further device, which for example has a heating source, can be pivoted on the pressure element about the same axis or arranged on one of the surfaces of the pressure element.

In yet another preferred embodiment of the

Clamping device comprises the pressure element at least two

Holding means with surfaces facing the counter element, one of the coverings being arranged on each of the surfaces. The areas are independent of each other towards and from the counter element

Counter element movable away to assign one of the pads to the counter element. The holding means can, for example, have a strip shape and can be arranged one behind the other and / or next to one another when viewed in the machining direction.

The surfaces of the holding means or the holding means themselves can be moved toward and away from the counter element, preferably independently of one another. The closer to the counter element

arranged surface is assigned to the counter element. In this embodiment, the holding means themselves can be approximated to the counter element, which in the sense of the invention is to be regarded as an approximation between the pressure element and the counter element.

In addition to the holding means on which the coverings are arranged, in this embodiment the clamping device can also have at least one further holding means with one in the direction

Counter-facing further surface can be provided, on which at least one adhesive element, for example a suction element for sucking firmly on the plate-shaped object, for example the glass pane, is arranged.

It is preferred if at least one cleaning device, in particular with a clamping device according to the other

Embodiments, such in the area of the pressure element

is arranged that the cleaning device along

at least one surface of the pressure element is movable. In a clamping device according to yet another embodiment, for example, a single cleaning device can be provided for cleaning one of the holding means or all holding means of the pressure element. It is also possible for each holding device to be assigned its own cleaning device. In the context of the invention, the can

Clamping device / s provided

Have brushes, in particular rotatable round brushes, and / or suction nozzles in order to clean the covering or coverings. However, it is also conceivable that the covering (s) from the

Cleaning device (s) is / are cleaned by means of vibrations or by using a cleaning fluid, such as compressed air. Such cleaning facilities can

Surfaces of the plate-shaped objects, for example the glass panes, are optimally protected without manual

Cleaning work must be done.

It is also conceivable within the scope of the invention that

Counter element in addition to at least one covering, or

instead, has at least one adhesive element for adhering to the plate-shaped object, for example the glass pane, with which it can be fixed. The adhesive element can, for example, be a suction element for sucking the

plate-shaped object.

For example, it is preferred within the scope of the invention if

Coverings consist of different materials and / or have different structures, for example surface structures. Preferably there is

at least one of the coverings made of textile, for example made of felt, and / or at least one of the coverings made of plastic,

especially made of rubber or polyurethane. Thereby are on

different types of plate-shaped objects,

for example coated or uncoated or

surface-treated or untreated glass panes, customized coverings can be selected.

In the context of the invention, embodiments are also considered in which two coverings made of the same material,

for example made of rubber, but another Surface structure, for example a covering a smooth one

Surface and another covering have a lamella surface. Embodiments are also conceivable in which two coverings consist of different materials, for example one made of rubber and another covering made of polyurethane, but both have the same surface structure, for example a smooth surface. More usable

Materials for the coverings are, for example, ethylene-propylene-diene rubber (EPDM), natural rubber (NBR) and / or

Polyvinyl chloride (PVC).

It is particularly preferred if the counter element in the

Essentially how the pressure element is constructed and has the same coverings as the pressure element, or if the counter element has different coverings from the coverings of the pressure element, one of which is assigned to the pressure element. For example, it is preferred if the counter element is designed like one of the pressure elements of one of the three preferred embodiments described. The pressure element and the counter element can be essentially the same or can also have differences from one another. For example, the printing element according to one of the three preferred

Embodiments and the counter element may be formed according to another of the preferred embodiments.

It is also preferred within the scope of the invention if the coverings of the counter element, which is designed like the pressure element, consist of the same or a different material or of the same or different materials as the coverings of the pressure element.

Furthermore, it is advantageous if the coating of the counter element, which is assigned to the pressure element, can be exchanged with the coating of the pressure element, which is assigned to the counter element, or independently of it. Thereby can be plate-shaped objects, for example glass panes, which are treated equally on both sides, for example

are coated, but also plate-shaped objects that are treated differently on both sides, for example

coated, are particularly gently clamped.

Preferably, a clamping device according to the invention according to one of the previously described embodiments is used to carry out the method according to the invention.

The invention also relates to a cutting system for dividing a plate-shaped object, for example a glass pane, preferably a laminated glass pane, along a dividing line. The cutting system has at least one first and at least one further clamping device for fixing to the plate-shaped object, for example the glass pane, on both sides of the dividing line, and a cutting device for producing at least one gap in the plate-shaped

Object, for example the glass pane, along the

Dividing line. According to the invention that is

Procedure can be carried out with the cutting system. It is particularly preferred if at least one of the clamping devices has one

inventive clamping device according to one of the described embodiments. For example, both are

Clamping devices according to one of the previously described

Embodiments executed.

Such cutting systems are particularly for the sharing of

Laminated glass panes are provided, the laminated glass panes generally consisting of two glass panes, between which a plastic film is arranged. In order to split a laminated glass pane along a dividing line, the glass panes are scored along the dividing line in a first process step and broken along the scored line in a subsequent process step. This creates a gap in each of the glass panes generated. Then the glass panes are held on both sides of the column by clamping devices and moved away from each other, so that the gap is opened and the between the

Glass panes arranged film is stretched. In a further process step, the film is, for example, by

Exposure to heat or with the help of a cutting tool,

severed so that the laminated glass pane along the

Dividing line is divided.

1 and 2 show a clamping device 1 according to the invention according to a first embodiment with a pressure element 2 and a counter element 3, between which in a support plane 4 a plate-shaped object 5 - in the example shown, one

Laminated glass pane - is arranged.

The pressure element 2 has a holding means 6 with a

Counter element 3 facing surface 7. On the surface 7, a carrier 8 is arranged, which along the surface 7 and in

Is essentially parallel to the support level 4.

The carrier 8 is a in the illustrated embodiment

Strap made of flexible material with two ends. Each of the ends is fastened to a roller 9, the rollers 9 being positioned on both sides of the holding means 6. By rolling up the carrier 8 on one of the rollers 9 and

Unwinding the carrier from the other roll 9, the carrier 8 can be moved along the surface 7 of the holding means 6.

A first covering 11a and at least a second covering 11b are arranged on the side of the carrier 8 which does not abut the surface 7 and which faces the support plane 4 and away from the holding means 6. The two linings 11a and 11b arranged next to one another on the carrier 8 are separated from one another by an intermediate section 13

spaced. If there are more than two linings 11a and 11b, an intermediate section 13 is provided between two linings 11a and 11b. However, an embodiment (not shown) is also conceivable within the scope of the invention, in which the pads 11a and 11b connect directly to one another.

By moving the carrier 8, one of the coverings 11a or 11b is optionally positioned between the holding means 6 of the pressure element 2 and the counter element 3. Thus, the first covering 11a, the second covering 11b, or, in the case of more than two coatings, one of these coatings is assigned to the counter element 3.

In Fig. 1, the pressure element 2 and the counter element 3 are not approximate to each other, so that in between in the

Support level 4 arranged plate-shaped object 5 is not clamped. In contrast, in FIG. 2 the pressure element 2 and the counter element 3 are approximated to one another and the plate-shaped object 5 is clamped between the holding means 6 of the pressure element 2 and the counter element 3.

Furthermore, in FIG. 2, the first covering 11a of the pressure element 2 is assigned to the counter element 3, so that the pressure element 2 is located on one side of the plate-shaped element via the first covering 11a

Object 5 rests, whereas in FIG. 1 the counter-element is assigned the second covering 11b.

When the clamping device 1 is fixed on the plate-shaped object, for example the glass pane 5, as in FIG.

2 - the intermediate section 13 or the abutting edge preferably not between the holding means 6 and the

Glass pane 5 arranged and for example laterally of the

Holding means 6 positioned. In the area of the carrier 8 there are cleaning devices 12

arranged, with which surfaces of the coverings 11a and 11b, which bear against the glass pane 5 when the clamping device 1 is fixed, can be cleaned. 1 and 2, the cleaning devices 12 have rotatable brushes 14 which are arranged on the side of the holding means 6.

3 and 4 show detailed views of the clamping device 1 shown in FIGS. 1 and 2 with different ones

Alternatives to that shown in Fig. 1

Cleaning device 12.

In FIG. 3, the cleaning device 12 arranged on the side of the holding means 6 has a suction nozzle 15 instead of the brush 14, whereas in FIG. 4 the cleaning device 12 has both a rotatable brush 14 and a suction nozzle 15 arranged next to it.

5 shows a clamping device 1 according to a variant of the first embodiment with an alternative pressure element 2, in which the carrier 8 is a flexible, self-contained, endless belt. On the carrier 8 are three of each other

various coverings, namely a first covering 11a, a second covering 11b and yet another covering 11c, are arranged.

The carrier 8 is via lateral rollers 9 and one

Tension roller 17 guided around the holding means 6. By

Adjustment of the tension roller 17 to the holding means 6 and from

Retaining means 6 is the belt tension of the carrier 8th

adjustable.

Fig. 6 shows the clamping device 1 according to another

Variant of the first embodiment, in which the counter element 3 is designed essentially like the pressure element 2, and like this a holding means 6 and a carrier 8 which can be displaced thereon with coverings 11a, 11b. The counter element 3 in FIG. 6 is designed like the pressure element 2 from FIGS. 1 and 2, but can also be designed like the alternative pressure element 2 from FIG. 5 within the scope of the invention.

7 to 10 each show the pressure element 2 of the

Clamping device 1 according to the invention according to a second

Embodiment. In the second embodiment, this is

Pressure element 2 rotatable about an axis 19.

FIG. 7 shows the pressure element 2 with a pyramid-shaped head 20, which has a first surface 7 and further surfaces 18a, 18b, 18c, viewed from below and in the direction of the axis 19 shown in FIG. 8.

Coverings 11a, 11b, 11c are arranged on three of the surfaces 7, 18a, 18b and adhesive elements 21 are arranged on one of the surfaces 18c.

FIG. 8 shows a section through the pressure element 2 shown in FIG. 7 along the one shown in FIG. 7

Section plane VIII-VIII. The head 20 of the pressure element 2 points to the glass pane 5. The axis 19 of the pressure element 2, which runs centrally through the pyramid-shaped head 20, is inclined at an angle to the plate-shaped object 5 and to the support plane 4, in which the plate-shaped object 5 is arranged.

For example, the pressure element 2 can be rotated about the axis 19 with the aid of a shaft 22, which is shown uncut in FIG. 8. As a result, one of the surfaces 7, 18a, 18b, 18c of the pressure element 2 can be aligned essentially parallel to the plate-shaped object 5. A covering 11a, 11b, 11c arranged between the pressure element 2 and the plate-shaped object 5 can be regarded in the sense of the invention as assigned to the counter element 3, not shown in FIG. 8. 9 shows the pressure element 2 according to a variant of the second embodiment of the clamping device 1 viewed from the side and in the direction of the axis 19, about which the pressure element 2 can be rotated.

In this variant, the pressure element 2 is a bar with an essentially square cross section and has four surfaces 7, 18a, 18b, 18c. On three of the surfaces 7, 18a, 18b

Coverings 11a, 11b, 11c and adhesive elements 21 are arranged on surface 18c. For example, one of the coverings 11c has a different surface structure than the other coverings 11a, 11b.

The axis 19, about which the pressure medium 2 can be rotated, runs parallel to the plate-shaped object 5. As a result, by rotating the pressure element 2 about the axis 19, each of the

Surfaces 7, 18a, 18b, 18c essentially parallel to

Align plate-shaped object 5. In this variant of the second embodiment, too, a covering 11a arranged between the pressure element 2 and the plate-shaped object 5 is

11b, 11c in the sense of the invention as that in FIG. 9 is not

counter element 3 shown assigned to view.

10 shows the pressure element 2 according to a further variant of the second embodiment of the clamping device 1, also viewed in a side view and in the direction of the axis 19.

The pressure element shown in FIG. 10 is essentially designed like the pressure element 2 in FIG. 9 with which

Difference that it has a triangular cross section and therefore only has three surfaces 7, 18a, 18b.

In addition, another device 23 is shown in FIG. 10

shown, which is pivotable about the same axis 19 as the pressure element 2 - but independently of it. This facility 23 has a heating element 24, for example. Thus, when the plate-shaped object is designed as a laminated glass pane, a plastic film can be placed between the glass panes

Laminated glass pane heated in the area of a gap 25 and severed. It is also conceivable within the scope of the invention to use such a device 23 in the same way in the case of FIG.

9 shown variant of the pressure element 2 to provide.

11 shows a pressure element 2 according to a third

Embodiment of the clamping device 1 in a side view.

In this embodiment, the pressure element 2 has a first holding means 6 and a second holding means 26. The first surface 7 of the first holding means 6, on which the first covering 11a is arranged, and the second surface 18a of the second

Holding means 26, on which the second covering 11b is arranged, run parallel to the plate-shaped object 5 or to the support plane 4 and are directed towards the latter.

In the first position of the pressure element 2, which is shown on the right in FIG. 11, the first holding means 6 with the first surface 7 approximates the plate-shaped object 5 and the counter element 3, not shown in FIG 3 is assigned. In a further position, which is shown in the middle in FIG. 11, the second holding means 26 with the second surface 18a is not the plate-shaped object 5 and that in FIG. 11

counter element 3 shown approximated so that the second covering 11 b is assigned to the counter element 3. In another
