Furthermore, the present invention relates to the use of a Zustelltisches invention.

STATE OF THE ART

For coating plate-shaped objects,

especially with paint, it is necessary to align the plate-shaped objects, preferably on a support surface, precisely so that by means of linearly movable sieves,

Inking rollers or other applicators,

especially in the context of screen printing, rolling or

Spray method, the coating, in particular paint, can be applied to the desired locations. Pattern off For example, straight lines should run exactly parallel to a plate edge of a rectangular glass plate in the desired shape. Such a device for aligning in the form of a Zustelltisches is known for example from the utility model AT 13.360 U.

The demands on the functionality of such devices are increasing in size, as the range of dimensions of plate-to-be-coated objects to grow steadily and currently ranges from a few decimeters to several meters edge length. Accordingly, it is a big challenge, plate-shaped objects

to be able to precisely align and align a wide variety of sizes, especially since the alignment is as large as possible

Angle range should be possible and manipulating the plate-shaped object may not cost too much time.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide a

to provide alternative Zustelltisch available, which allows the precise alignment and process of plate-shaped objects of different dimensions saving time.

PRESENTATION OF THE INVENTION

To solve the above problem, it is in a Zustelltisch for a plate-shaped object, the Zustelltisch

comprising conveying means for rectilinear conveying the

a plate-shaped object parallel to a first direction and a rotating device for rotating the plate-shaped object about an axis of rotation which is parallel to a third direction, wherein the third direction is normal to a plane of the Zustelltischs and the plane of Zustelltischs is spanned by the first direction and a normal standing on this second direction,

According to the invention, the rotary device has a main arm, which is rotatable about a first axis of rotation, and at least one additional arm, which is rotatably mounted on the main arm about a second axis of rotation, wherein the first axis of rotation and the second axis of rotation are parallel to the third direction. That the first direction, the second direction and the third

Direction are mutually normal to each other. By the at least one additional arm is rotated so that it protrudes from the main arm in a, preferably right, angle, large plate-shaped objects can be supported and rotated by the rotating device according to the invention. In this case, the at least one additional arm can be rotatably mounted in an end region of the main arm at this, in order

support or hang up on the turning device. For supporting the at least one additional arm on the main arm, a bearing element connected to the main arm or fixed thereto may be provided.

The rotatable mounting of the additional arm can along a

Longitudinal axis of the additional arm seen in the region of its center, to a stable construction as possible and the

To allow circulation of heavy plate-shaped objects on the rotating device.

Basically, the alignment of the plate-shaped

Thus object done by rotating the main arm about the first axis of rotation. Especially for large plate-shaped objects that is the preferred way of

Alignment. For example, with the delivery table according to the invention a rectangular glass plate of up to 3 m, preferably up to 6 m in length and up to 3.21 m in width easily manipulated and accurately fed to a processing device. It should be noted that a

basic limitation to a maximum disk size does not exist, i. the Zustelltisch invention can easily longer for the manipulation and / or

wider plate-shaped objects, in particular

Glass plates, to be designed.

In this case, the plate-shaped object is supplied with the conveying means of the rotating device and with the rotating device - in the described case by rotation of the main arm about the first axis of rotation - rotated accordingly and preferably also

according linear process, these steps (turning one hand, procedures on the other hand) in principle

one after the other or simultaneously.

The processing device may be a

Coating device act, for example, based on screen printing, rolling, spraying or digital printing, the coating, in particular paint, applied to the desired locations. It is also possible to apply any desired patterns, not just rectilinear ones. However, the processing device can - alternatively or additionally - for others

Processing steps may be provided, e.g. for milling.

Insofar as the plate-shaped object has smaller dimensions or an average size and can be supported or placed on it exclusively by a single additional arm, the alignment of the plate-shaped

Subject matter in principle also by turning the additional arm about the second axis of rotation can be done alone, without requiring the main arm must be rotated. For example, in this way a rectangular glass plate of 1 m to 2 m in length and 1 m to 2 m wide easily manipulated and the

Processing device to be fed exactly. Again, the plate-shaped object is supplied with the conveying means of the rotating device and with the

Turning device - in this case by rotation of the additional arm about the second axis of rotation - rotated accordingly and

preferably also correspondingly linear method, these steps (turning on the one hand, method on the other hand)

in principle, one after the other or simultaneously. However, it is conceivable in this case, in addition to twist the main arm to a

to generate additional movement of the plate-shaped object, in particular when the plate-shaped

Object is arranged eccentrically to the first axis of rotation. Accordingly, this additional movement can be included in the said sequence of movements (rotation and procedure).

It would also be conceivable in the presence of several additional arms that several plate-shaped objects, each of which is placed on a single additional arm, can be rotated independently by each of the additional arms is rotated in accordance with its second axis of rotation. That

Preferably, the additional arms can be rotated independently of each other about their second axis of rotation.

Again, the plate-shaped objects with the

Turning device - in this case by rotation of the additional arms about the respective second axis of rotation - correspondingly rotated and proceed linearly with the funding, these steps (turning one hand, procedures on the other hand) are usually performed in a suitable sequence one behind the other and possibly iteratively. Also in this case, it is conceivable to turn the main arm in addition to a

to generate additional movement of the plate-shaped objects, in particular when the plate-shaped

Objects are arranged eccentrically to the first axis of rotation. Accordingly, this additional movement in the mentioned Sequence of movements (turning and procedures) are recorded.

In particular, to be able to align small plate-shaped objects suitable, it is in a preferred

Embodiment of the Zustelltisches invention

provided that at least one turntable at least one turntable is rotatably mounted about a third axis of rotation, which is parallel to the third direction. That If the plate-shaped object has small dimensions and can be supported or placed on it exclusively by a single turntable, the alignment of the plate-shaped object by turning the turntable about the third axis of rotation alone, without the additional arm and / or the main arm twisted Need to become.

For example, in this way a rectangular

Glass plate from 0.3 m to 1.3 m in length and 0.3 m to 1.3 m

Width easily manipulated and fed to the processing device exactly.

Again, the plate-shaped object with the

Conveyors fed to the rotating device and with the

Turning device - in this case by rotation of the turntable about the third axis of rotation - rotated accordingly and

preferably also linear process, these steps

(Turning on the one hand, procedures on the other hand) in principle, one after the other or simultaneously can be performed. However, it is conceivable in this case, the main arm and / or the additional arm, on which the turntable rotatable

is mounted, in addition to rotate, to produce an additional movement of the plate-shaped object,

especially when the plate-shaped object

is arranged eccentrically to the first axis of rotation and / or second axis of rotation. Accordingly, this additional movement can be included in the said sequence of movements (rotation and procedure). Analogous to the above, it would be conceivable in the presence of several turntables that several plate-shaped objects, each of which each on a single turntable

can be turned independently, turning each of the turntables accordingly around its third

Turning axis is rotated. That Preferably, the

Turntables are rotated independently of each other about their third axis of rotation.

Again, the plate-shaped objects with the

Conveyors fed to the rotating device and with the

Turning device - in this case by rotation of the turntable about the respective third axis of rotation - rotated accordingly and preferably also proceeded accordingly linear, these steps (turning on the one hand, method on the other hand)

in principle, one after the other or simultaneously. Also in this case, it is conceivable, the main arm and / or the at least one additional arm

in addition to rotate to produce additional movement of the plate-shaped objects, in particular when the plate-shaped objects are arranged eccentrically to the first and / or the respective second axis of rotation. Accordingly, this additional movement can be included in the said sequence of movements (rotation and procedure). In plate-shaped objects of medium size, a plurality of turntables of an additional arm can form a support for the respective plate-shaped object, in which case when aligning only the additional arm about the second axis of rotation and / or the main arm are rotated about the first axis of rotation. In the case of large plate-shaped objects, several turntables of a plurality of additional arms, possibly all turntables of all additional arms, form a support for the respective plate-shaped object, wherein only the main arm is then rotated about the first axis of rotation during alignment. In order to move the (at least one) plate-shaped object with the rotating device, it is preferably lifted from the latter by means of the rotary device after being fed by the conveying means and remains raised during the entire movement with the rotary device. It is sufficient if the plate-shaped object is lifted only slightly from the funding, for example, a few centimeters, typically 3 cm to 7 cm, in particular 5 cm. After the plate-shaped object has the desired position relative to the processing device, it is preferably lowered again to guarantee a stable position during processing with the processing device.

In a preferred embodiment of the Zustelltisches invention, it is provided that exactly two additional arms are provided. In practice, this configuration represents a mostly optimal compromise with respect to the

Design effort and the associated costs on the one hand and the editable size range of the moving plate-shaped objects on the other. In a preferred embodiment of the Zustelltisches invention, it is provided that exactly two turntable are provided for each additional arm. Again, this represents a mostly optimal compromise for the practice in terms of the design effort and the associated costs on the one hand and the editable size range of the moving plate-shaped objects on the other hand.

In particular, by two turntables per additional arm a secure support for large plate-shaped objects

allows. Especially with medium and small plate-shaped

It is sometimes not necessary for objects to allow the at least one additional arm to protrude at an angle from the main arm in order to provide support that is as stable as possible or support to allow the plate-shaped object. In this case, the rotating device can be arranged to save space. Therefore, in a preferred embodiment of the invention

according to the invention provided Zustelltisches that extends in a zero position, a longitudinal axis of each additional arm parallel, and preferably congruent, to a longitudinal axis of the main arm.

It should be noted, however, that in general an optimal

Adaptation of the turning device to the geometry of the

plate-shaped object is possible by suitable choice of an angle between the longitudinal axis of the main arm and the longitudinal axis of the at least one additional arm. For example, For example, the at least one additional arm may be rotated, typically within a range of 5 ° to 30 °, relative to the main arm, providing optimal support for a long, narrow arm

plate-shaped object is made possible. With several additional arms, it would also be conceivable that not all, but only one of the additional arms or some selected

Additional arms such an angle with the main arm

include and the remaining additional arms parallel to

Main arm are aligned. Especially if exactly two

Additional arms are present, it is conceivable that the longitudinal axis of one of the two additional arms with the longitudinal axis of the main arm at an angle greater than 0 ° but less than 90 °, preferably an angle in the range of 5 ° to 30 °, with the longitudinal axis of

Main arm includes and the other of the two additional arms is aligned parallel to the main arm. Of course, situations are possible in which both or

all additional arms are aligned in parallel and enclose the same angle with the main arm.

In order to arrange the rotation device particularly space-saving, especially in small plate-shaped objects, it is in a particularly preferred embodiment of

according to the invention provided Zustelltisches that in the Zeroing the longitudinal axis of the main arm parallel to the first direction. It can therefore be achieved an arrangement of the turntable, in which all turntables are on a line which is parallel to the first direction. In a preferred embodiment of the Zustelltisches invention, it is provided that the rotating device is movable parallel to the first direction and / or to the second direction and / or to the third direction. On the one hand, this allows a certain process of the plate-shaped

Object parallel to the first direction are made possible without the need for this funding must be used. In this way, the plate-shaped object can be

Time-saving and extremely precise linear movement.

The ability to move the plate-shaped object by means of the rotating device also parallel to the second direction, allows an overall larger area in which the plate-shaped object can be moved without the movement would have to be parallel to the second direction forcibly by other means than the rotating device. The possibility of the plate-shaped object by means of

Turning device also to move parallel to the third direction, provides an easy way to the plate-shaped

To decouple the object from the funding, in particular by the plate-shaped object by means of

Turning device is simply lifted off the conveyor upwards. Conversely, of course, the

Turning device of the plate-shaped object in a simple manner (again) are decoupled, in particular by the rotating device is lowered down and the

plate-shaped object thereby comes to rest on other elements of the Zustelltischs, in particular on the funding. That is, in this way the coupling to the conveyor (again) could be made. In order to move the entire turning device parallel to the third direction, the main arm can be moved along the third direction, for example by means of at least one pneumatic, hydraulic or electric cylinder.

Preferably, this movement takes place along the first

Rotation axis.

In particular, if medium-sized plate-shaped objects to be lifted from the linear funding, rotated and possibly placed on this again, is sometimes a

Additional arm large enough to ensure full support and secure support of the plate-shaped object. That In this case, only the respective additional arm has to be moved parallel to the third direction, which can be done for example by means of at least one pneumatic, hydraulic or electric cylinder. To make this possible, it is at a preferred

provided that the at least one additional arm is movable parallel to the third direction relative to the main arm.

This movement preferably takes place along the respective second axis of rotation.

In particular, if small plate-shaped objects are to be lifted from the linear conveyors, rotated and placed on them again, sometimes a turntable is large enough to ensure complete support and secure seating of the plate-shaped object. That in this case, only the respective turntable must be moved parallel to the third direction, which

For example, by means of at least one pneumatic, hydraulic or electric cylinder can be done. To make this possible, it is at a preferred

Embodiment of the Zustelltisches invention

provided that the at least one turntable parallel to the third direction relative to the at least one additional arm is movable. This movement preferably takes place along the respective third axis of rotation.

Basically, from the prior art, a variety of ways for the realization of suitable linear

provided that the funds at least one,

preferably comprise a plurality of parallel belt conveyors. Usually, the plate-shaped object is in its conveyance by the belt conveyor due to gravity on this. It would also be conceivable, however, to provide the belt conveyors with suitable adhesives in order to make the plate-shaped object particularly stable, and preferably easily detachable, to fix on the belt conveyors, e.g.

by means of magnets, preferably electromagnets, or

Intake devices.

On the one hand a stable position of the plate-shaped

To ensure rotation with this, it is provided in a particularly preferred embodiment of the Zustelltisches invention that the rotating device is disposed between two belt conveyors.

In order to move the plate-shaped object over greater distances parallel to the second direction, it is in a preferred embodiment of the invention Zustelltisches provided that the conveying means are movable parallel to the second direction. Preferably, each conveying means, in particular each belt conveyor, can be moved individually parallel to the second direction, ie independently of another conveying means, in particular other

Belt conveyors. In the case of arranged between two conveyors or belt conveyors rotating device, the

Belt conveyors are also moved together with the rotating device parallel to the second direction, without the

Turning device abuts one of the belt conveyor.

Preferably, the turning device is always arranged parallel to the second direction in the middle between the two belt conveyors.

The Zustelltisch invention is particularly suitable for plate-like objects

To supply processing device, in particular for coating, in a highly precise and effective manner.

Accordingly, according to the invention is a use of a

Delivery table according to the invention for supplying the

plate-shaped object to a processing device for processing, preferably coating, in particular an edge, the plate-shaped object provided. The precise processing or coating of edge regions of plate-shaped objects is an increasingly frequently demanded requirement in the glass industry. Accordingly, it is provided in a preferred embodiment of the inventive use that the plate-shaped object is a glass plate.

In particular, when the Zustelltisch invention is used for the supply of glass plates, it is advantageous to perform the turntable as a sucker, which have a suction function to selectively suck the glass plate resting on and so fix or release. Such suckers with such a suction function are known per se. Of course, with such suckers and the suction of others

In particular, if the delivery table according to the invention for the delivery of frame profiles, such. Window frames,

is used, it is advantageous to perform the turntable as a gripper, which can attack in particular on the frame profile to fix this or release optional.

Such grippers with such a gripping function are known per se. Of course, with such grippers and the gripping of other plate-shaped objects possible, especially if they have a frame or a frame profile on which the gripper can attack.

WAYS FOR CARRYING OUT THE INVENTION

In the plan view of Fig. 1, an embodiment of a Zustelltisches 1 according to the invention is shown, on which a plate-shaped object in the form of a (large) glass plate 2 is arranged. In the illustration of FIG. 1 is the

Glass plate 2 square executed with a side length of typically 2.7 m.

By means of the Zustelltisches 1, the glass plate 2 a

Processing device 8 supplied, in particular to edit an edge region of the glass plate 2, preferably to coat. The processing device 8 is shown in Fig. 1 only schematically by the L-shaped structure

illustrated.

The Zustelltisch 1 has two belt conveyors 3a, 3b, with which the glass plate 2 can be moved parallel to a first direction 4. In Fig. 1, the glass plate 2 is shown by dashed lines in a position in which they to the

Zustelltisch 1 is introduced and is located immediately before the support on the belt conveyors 3a, 3b. The

solid lines represent the glass plate 2 after their linear promotion by the belt conveyors 3a, 3b parallel to, more precisely opposite, the first direction 4. This linear promotion or conveying movement is shown in Fig. 1 by the arrow (without reference numeral) next to the dashed line

indicated glass plate 2 indicated. A second direction 5 is normal to the first direction 4 and spans a plane of the Zustelltisches 1, which plane is parallel to the plane of Fig. 1. A third direction 6 is normal to this plane and protrudes in Fig. 1 out of the plane. That is, the three directions 4, 5, 6 are mutually normal to each other. To the glass plate 2 for the coating relative to

Machining device 8 to be able to align as desired, the Zustelltisch 1 next to the belt conveyors 3a, 3b, a rotating device 7, by means of which the glass plate 2 can be rotated about a direction parallel to the third direction 6 axis of rotation.

For this purpose, the rotating device 7 on a main arm 9, which is about a first axis of rotation 12, preferably by means of a

Electric motor 21, is rotatable, see. Fig. 2. The first

The axis of rotation 12 is arranged parallel to the third direction 6 and along a longitudinal axis 16 (see Fig. 3) of the main arm 9 in the region of the center of the main arm 9.

In the region of the two ends of the main arm 9 are two

Additional arms 10a, 10b rotatably supported about second axes of rotation 13a, 13b on the main arm 9, wherein the second axes of rotation 13a, 13b are parallel to the third direction 6. The second

Rotary axes 13a, 13b are arranged along longitudinal axes 17a, 17b (see FIG. 3) of the additional arms 10a, 10b in the region of the centers of the additional arms 10a, 10b. The additional arms 10a, 10b can preferably be rotated by means of electric motors 21 about the second axes of rotation 13a, 13b.

In the region of the two ends of each additional arm 10a, 10b, a turntable IIa, IIb, 11c, 11d is respectively rotatably mounted on the respective additional arm 10a, 10b about third axes of rotation 14a, 14b, 14c, 14d, which are parallel to the third direction 6. That is, the additional arm 10a has the turntables IIa, IIb with the third axes of rotation 14a, 14b and the additional arm 10b, the turntable 11c, lld with the third axes of rotation 14c, 14d. The turntables IIa, IIb, 11c, lld can preferably by means of Electric motors 21 are rotated about the third axes of rotation 14a, 14b, 14c, 14d.

In the illustrations of FIGS. 1, 2, 3 and 4, the additional arms 10a, 10b are rotated around the second axes of rotation 13a, 13b such that the additional arms 10a, 10b project at right angles from the main arm 9. That the longitudinal axes 17a, 17b of the additional arms 10a, 10b close to the longitudinal axis 16 of the

Main arm 9 each a right angle. In this way, the rotating device 7 covers a large area, and it can be easily picked up by the rotating device 7 large plate-shaped objects or glass plates 2.

be supported and moved without the risk that the respective glass plate 2 gets out of balance and tilts down from the rotating device 7. The recording of the belt conveyors 3a, 3b resting

Glass plate 2 on the rotary device 7 is made by moving the rotary device 7 in the third direction 6. Thereby, the glass plate 2 is first contacted by the turntables IIa, IIb, 11c, lld and then lifted off the belt conveyors 3a, 3b, i. decoupled from the belt conveyors 3a, 3b.

Preferably, the turntables IIa, IIb, 11c, lld are designed as suckers to fix the glass plate 2 by suction and so avoid unwanted slippage of the glass plate 2 can. In order to move the rotating device 7 parallel to the third direction 6, in the illustrated embodiment, a bearing element 22, on which the main arm 9 is rotatably mounted about the first axis of rotation 12, in a rail 20, which is parallel to the third direction 6, out, see. Fig. 2. The movement along the rail 20 by means of an electric motor 21 in a conventional manner, for example by the electric motor 21 a pinion (not shown) drives, which with a rack (not shown) in Intervention is. In principle, however, at least one pneumatic, hydraulic or electric cylinder could also be provided for moving the rotary device 7 or the main arm 9 parallel to the third direction 6, for example. When the glass plate 2 is decoupled from the belt conveyors 3a, 3b by lifting, the glass plate 2 can be rotated by rotation of the main arm 9 about the first rotation axis 12 by a rotational angle α, as illustrated in FIG. Of the

Angle of rotation α can cover an angular range of at least 180 ° in order to allow the coating of two opposite regions of the glass plate 2 by corresponding rotation of the glass plate 2. Preferably, the angle of rotation α covers an angular range of at least 360 °.

Furthermore, in Fig. 3, a rotation angle ß is drawn, by which the additional arms 10a, 10b can be basically rotated about the respective second rotation axis 13a, 13b, e.g. in order to adapt the geometry of the rotary device 7 to the geometry and / or dimensioning of the glass plate 2 to be moved or to a medium-sized or small glass plate 2 which is only supported on one or both turntables IIa, IIb; 11c, lld one

single auxiliary arm 10a; 10b rests to turn.

Typically, the dimensions of a medium sized

Glass plate 2, on both turntables IIa, IIb; 11c, lld of a single auxiliary arm 10a; 10b, in the range of 1.25 m to 1.75 m in length and 1.25 m to 1.75 m in width. Large glass plates 2 typically have longer lengths and / or larger widths. Dimensions of a small glass plate 2 which rests on a single one of the turntables IIa, IIb, 11c, lld are typically in the range of 0.4 m to

1.25 m long and 0.4 m to 1.25 m wide.

Finally, in Fig. 3, a rotation angle γ is located to the turntable IIa, IIb, 11c, lld to the respective third rotary axes 14a, 14b, 14c, 14d can be rotated to a small glass plate 2, which rests only on one of the turntables IIa, IIb, 11c, Lld rotate. The angles of rotation β and γ can each have an angular range of at least 180 °

Cover to allow the coating of two opposite areas of the glass plate 2 by turning the glass plate 2 accordingly. Preferably, the cover

Rotation angle ß and γ each have an angular range of at least 360 °. Of course, the glass plate 2 can also be lowered again. The lowering can be made to deposit the glass plate 2 on the processing device 8. In this case, for better support of the glass plate 2, this still supported by the rotating device 7 and fixed by means of the designed as a sucker turntable IIa, IIb, 11c, lld.

Theoretically, it would also be possible, the glass plate 2 through

Lowering again on the belt conveyors 3a, 3b hang up in order to move them with the belt conveyors 3a, 3b can. In this case, the rotating device 7 would be lowered so far that it is no longer in engagement with the glass plate 7, in particular that the turntable IIa, IIb, 11c, lld the

Do not touch the glass plate 2, whereby its suction function would be deactivated. Preferably, each of the additional arms 10a, 10b and each of the turntables IIa, IIb, 11c, Lld are individually moved parallel to the third direction 6, for example by means of pneumatic cylinder (not shown). Thus, for the raising and lowering of medium-sized and small glass plates 2, the entire rotating device 7 or the main arm 9 does not always have to be moved up and down. As can be seen in particular from FIG. 2, the rail 20 in turn is linearly guided by means of a rail 18 which runs parallel to the first direction 4. That is, the rail 20 and thus the entire rotating device 7 can be moved along the rail 18. The movement along the rail 18 takes place in the illustrated embodiment by means of a

Electric motor 21 in a conventional manner, for example by the electric motor 21, a pinion (not shown) drives, which is in engagement with a rack (not shown). Thus, the glass plate 2, when it rests on the rotating device 7 and on the turntables IIa, IIb, 11c, lld and raised, are moved very precisely and quickly linearly parallel to the first direction 4, without requiring a decoupling with the Turning device 7 and a

Coupling with the belt conveyors 3a, 3b would be necessary.

The rail 18 is mounted on a parallel to the first direction 4 extending crossbar 23, which in turn is guided at its ends in rails 19 which are parallel to the second direction 5. That the rail 18 and thus the entire rotating device 7 can be moved along the rails 19. The movement along the rails 19 takes place in the illustrated embodiment by means of at least one electric motor 21 in a conventional manner, for example by the at least one electric motor 21, a pinion (not shown) drives, which (not shown) is in engagement with a rack. Thus, the glass plate 2, when it rests on the rotating device 7 and on the turntables IIa, IIb, 11c, Lld and raised, very precise and quickly linearly parallel to the second direction 5, are moved.

4 illustrates a situation in which the glass plate 2 resting on the rotating device 7 with respect to the position shown in FIG. 1 parallel to, more precisely opposite, the first direction 4 and parallel to the second direction. 5 moved or moved. The arrows without reference indicate the direction of movement.

In the illustrated embodiment, the rotating device 7, in particular seen in the second direction 5, between the belt conveyors 3a, 3b, preferably centrally located. The belt conveyors 3a, 3b are in turn provided with further transverse beams 24a, 24b extending parallel to the first direction 4

connected. This connection is not shown separately in FIG. 2 for reasons of clarity. Each of the further transverse bars 24a, 24b is in turn guided in the rails 19 and can be moved along the rails 19, whereby the belt conveyors 3a, 3b can be moved parallel to the second direction 5. The movement of the further crossbars 24a, 24b along the rails 19 in the illustrated embodiment by means of at least one electric motor 21 in a conventional manner, for example by the at least one electric motor 21 a pinion (not shown) drives, which with a rack (not shown) engaged.

Thus, when the rotary device 7 is moved parallel to the second direction 5, the belt conveyors 3a, 3b can also be moved by a corresponding amount parallel to the second direction 5, so that the relative arrangement between the rotary device 7 and the belt conveyors 3a, 3b in the second direction 5 can be kept substantially constant.

Theoretically, the glass plate 2, when placed on the

Belt conveyors 3a, 3b rests, with these not only parallel to the first direction 4, but also parallel to the second

Direction 5 are encouraged without necessarily for this purpose the rotating device 7 must be used.

Finally, the belt conveyors 3a, 3b can also be moved towards and away from each other parallel to the second direction 5, if no glass plate 2 (or no plate-shaped object) on the belt conveyors 3a, 3b rests. In this way, one can be parallel to the second

Direction 5 measured distance 25 of the belt conveyors 3a, 3b to each other to the size of the male glass plate 2 (or the male plate-shaped object) can be adjusted.

This distance 25 of the belt conveyors 3 a, 3 b can only be reduced to the extent that the spatial extent of the rotary device 7 in the second direction 5 permits, in particular if the glass plate 2 can continue to be rotated by the rotary device 7. In order to allow for the alignment of small glass plates 2 (or plate-shaped objects) small distances 25 between the belt conveyors 3a, 3b, both the main arm 9 and the

Additional arms 10a, 10b are aligned accordingly.

The smallest possible extension of the rotary device 7 in the second direction 5 results in a zero position 15, when the main arm 9 and the additional arms 10a, 10b are rotated about the axes of rotation 12, 13a, 13b, that the longitudinal axes 16, 17a, 17b all parallel and preferably congruent

run. In principle, zero positions 15 are possible in which the longitudinal axes 16, 17 a, 17 b do not run parallel to the first direction 4. The zero position 15 with the

However, the smallest possible extension of the rotary device 7 in the second direction 5 is given when the longitudinal axes 16, 17 a, 17 b are parallel to the first direction 4. These

Zero position 15 is illustrated in FIG.

The distance 25 of the belt conveyors 3a, 3b is smaller than the side length of a small glass plate 2, so that the small glass plate 2 after feeding to the Zustelltisch 1 on both belt conveyors 3a, 3b can rest and preferably

laterally beyond the belt conveyors 3a, 3b a little bit. In this case, the glass plate 2 is dashed in Fig. 5 in a Position shown, from which it to the Zustelltisch 1 parallel to, more precisely opposite, the first direction. 4

is introduced, wherein the arrow with no reference numeral illustrates the movement in the lead. On the two belt conveyors 3 a, 3 b lying can

Glass plate 2 then parallel to the first direction 4 by means of the belt conveyors 3a, 3b are moved, in particular to about one of the turntable IIa, IIb, 11c, lld, wherein in Fig. 5, the glass plate 2 is shown on the turntable Lld. If necessary, in addition, the rotating device 7 and thus the turntable Lld be moved parallel to the first direction 4 so until the turntable Lld is centrally located under the glass plate 2 and this can safely accommodate. For one

Rotation of the glass plate 2, this can therefore be raised by moving the rotary device 7 or the turntable lld alone in the third direction 6, until the glass plate 2 rests only on the turntable lld and from this

is supported. Preferably, the glass plate 2 is fixed by suction on the trained as a sucker turntable Lld. Then the turntable lld around its third

Rotary axis 14d are rotated by the desired angle γ to achieve the desired orientation of the glass plate 2.

It is understood that in this case, too, the rotating device 7 can be moved parallel to the first direction 4 in order to move the glass plate 2 resting on the turntable 2 parallel to the first direction 4. Furthermore, in this case too, the rotating device 7 - together with the belt conveyors 3 a, 3 b, can be moved parallel to the second direction 5 in order to move the glass plate 2 resting on the turntable 2 parallel to the second direction 5.

Theoretically, the movement of the glass plate 2 could of course also, as described above, by moving the belt conveyors 3a, 3b - together with the rotating device 7 - parallel to second direction 5 are moved when the glass plate 2 rests on the belt conveyors 3a, 3b.

As already mentioned, the rotating device 7 to the

Geometry of each to be moved and aligned

Glass plate 2 can be adjusted by rotation of the additional arms 10a, 10b. By way of illustration, an arrangement with an oblong rectangular glass plate 2 is shown in Fig. 6, which is rotated with the rotating device 7. The longitudinal axes 17a, 17b of the additional arms 10a, 10b are located in a relation to the longitudinal axis 16 by about 15 ° twisted parallel arrangement to optimally support the long narrow glass plate 2.

Finally, with reference to FIG. 1, a typical

Alignment process be described as he at a

circumferential coating of the edge of the glass plate 2 may occur. After the glass plate 2 by means of the belt conveyors 3 a, 3 b of the rotary device 7 is supplied and by means of

Turning device 7 was raised and only on the

Turntables IIa, IIb, 11c, lld rests, the glass plate 2 in the second direction 5 to an imaginary first

Reference line 26, which is parallel to the first direction 4, with the rotating device 7 to move. Sensors 29 register when a first edge 31 of the glass plate 2 reaches the position of the respective sensor 29, and send a corresponding signal, e.g. can be evaluated with a control unit (not shown). In this case, the first edge 31 is that which, viewed in the second direction 5, the glass plate. 2

concludes. The sensors 29 are arranged on a line which runs parallel to the first direction 4. Therefore, it can be determined exactly by the sensor signals by how many degrees the first edge 31 is rotated relative to the first reference line 26 or relative to the first direction 4. According to this information, after the movement in the second direction 5 is stopped, the glass plate 2 is moved by the corresponding amount rotated, wherein in the embodiment of FIG. 1, the rotation about the first axis of rotation 12 takes place. Now, the first edge 31 is perfectly parallel to the first reference line 26.

Since the glass plate 2 is rectangular, a second edge 32, with which the glass plate 2 begins as seen in the first direction 4, is perfectly parallel to an imaginary second one

Reference line 27, which is parallel to the second direction. 5

runs. Now, the glass plate 2 against the first

Direction 4 moves toward the second reference line 27 until the second edge 32 reaches the position of another sensor 30, which registers this and sends a corresponding signal. Thus, the orientation and position of the

Glass plate 2 completely known, and can be given with respect to a reference point 28. The reference point 28 is selected in the embodiment of FIG. 1 as an intersection of the two reference lines 26, 27, but can basically be arbitrarily set, if its position with respect to the sensors 29, 30 is known.

The position of the first reference line 26 along the second direction 5 may be selected such that a strip to be coated with a desired width in the second direction 5 results when the first edge 31 of FIG

Glass plate 2 is brought to coincide with the first reference line 26. Likewise, the position of the second

Reference line 27 may be chosen so that a to

coating strip having a desired width in the first direction 4 results when the second edge 32 of the

Glass plate 2 is brought to coincide with the second reference line 27. The coverage of the first edge 31 with the first reference line 26 and the coverage of the second edge 32 with the second

Reference line 27 may be parallel to the second direction 5 and the first direction 4 by moving the rotating device 7 be achieved, so that the glass plate 2 with respect to the first direction 4 and the second direction 5 now in a

Coating position is positioned. Possibly. must they

Belt conveyors 3a, 3b are moved with the rotating device 7 parallel to the second direction 5 in order to avoid a collision between the rotating device 7 and belt conveyors 3a, 3b. The glass plate 2 can now by processes of

Rotating device 7 are lowered counter to the third direction 6, so that the edge to be coated in the region of the first edge 31 and the second edge 32 of the glass plate 2 on the

Processing device 8 rests to perform the coating can. Preferably, the glass plate 2 is further supported by the rotating device 7 and fixed by means of the rotating plates IIa, IIb, 11c, lld designed as suction elements.

After coating, the glass plate 2 can be raised by means of the rotating device 7 again and by methods

parallel to the first direction 4 and the second direction 5 are brought into a central position in which a rotation of the glass plate 2 can be done by 180 °, without the glass plate 2 abuts the processing device 8 or other elements. If the dimensions of the glass plate 2 are known exactly, the glass plate 2 can be moved immediately after rotation by 180 ° in the coating position and

are lowered to coat the remaining edge of the glass plate 2. Otherwise, in the manner described above, the orientation and position of the glass plate 2 can be redetermined and then brought to the coating position to perform the coating. After the coating process is completed, the glass plate 2 is preferably returned to the center position

brought, where it can be lifted for example by a crane of the rotating device 7. Theoretically, it would also be possible to lower the glass plate 2 on the belt conveyors 3a, 3b and to promote with them the glass plate 2 away from the Zustelltisch 1, but this is usually much more time-consuming in practice.

Finally, it should be noted that the work to be done,

preferably coating, plate-shaped object or the glass plate 2 does not necessarily have to be rectangular, but for example, be triangular or otherwise may have a polygonal shape. In principle, it is even sufficient if the plate-shaped object or the glass plate 2 has at least one rectilinear edge. Thus, an orientation relative to this edge can be carried out analogously to the method described above, and machining, in particular coating, can take place in the region of this edge.
