DELIVERY TABLE FIELD OF THE INVENTION

The present invention relates to a Zustelltisch for a plate-shaped object, the Zustelltisch comprising conveying means for rectilinear conveying the 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 the Zustelltischs is spanned by the first direction and a normally standing on this second direction.

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

STATE OF THE ART

For the coating of plate-shaped objects, in particular with paint, it is necessary to align the plate-shaped objects, preferably on a support surface, so that by means of linearly movable screens, inking rollers or other applicators, especially in the context of screen printing, rolling or spraying, the coating, in particular paint, can be applied to the desired locations. Patterns of straight lines should e.g. in the desired shape exactly parallel to a plate edge of a rectangular glass plate. 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 so far greater, as the spectrum of dimensions of coated plate-shaped objects to grow steadily and currently ranges from a few decimeters to several meters edge length. Accordingly, it is a great challenge to be able to accurately move and align plate-shaped objects of different sizes, especially since the alignment should be possible over the largest possible angular range and the manipulation of 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 an alternative Zustelltisch available that allows the precise alignment and process plate-shaped objects of different dimensions saving time.

PRESENTATION OF THE INVENTION

To achieve the above object, it is in a Zustelltisch for a plate-shaped object, the Zustelltisch comprising conveying means for rectilinear conveying the plate-shaped object parallel to a first direction and a rotating device for rotating the plate-shaped object about an axis of rotation, which parallel to a third Direction is, wherein the third direction is normal to a plane of the Zustelltischs and the plane of the Zustelltischs spanned by the first direction and a normally standing on this second direction, according to the invention provided that the rotating device has a main arm which is rotatable about a first axis of rotation is, 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.

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 in an end region of the main arm to be rotatably mounted on this to support plate-shaped objects with a large area or hang up on the rotating device can. 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 be seen along a longitudinal axis of the additional arm in the region of its center to allow a stable construction and the support of heavy plate-shaped objects on the rotating device.

In principle, the alignment of the plate-shaped object can thus be done by rotating the main arm about the first axis of rotation. Especially for large plate-shaped objects, this is the preferred way of aligning. For example, with the Zustelltisch invention a rectangular glass plate of up to 3 m, preferably up to 6 m, length and up to 3.21 m width easily manipulated and accurately fed to a processing device. It should be noted that there is no fundamental limitation to a maximum disk size, i. the Zustelltisch invention can be easily for the manipulation of even longer and / or wider plate-shaped objects, especially glass plates, designed.

In this case, the plate-shaped object is supplied with the funding 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 proceeded according linear, these steps (turning one hand, method on the other hand) in principle, one after the other or simultaneously.

The processing device may be a coating device which, 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 may alternatively or additionally be provided for other processing steps, e.g. for milling.

If the plate-shaped object has smaller dimensions or an average size and supported exclusively by a single additional arm or can be placed on this, the alignment of the plate-shaped object can in principle be done by turning the additional arm about the second axis of rotation alone that for this, the main arm must be twisted. For example, a rectangular glass plate of 1 m to 2 m in length and 1 m to 2 m in width can be easily manipulated and exactly fed to the processing device in this way.

Again, the plate-shaped object is supplied with the conveying means of the rotating device and with the rotating device - in this case by rotation of the additional arm about the second axis of rotation - rotated accordingly and preferably also proceeded accordingly linear, these steps (turning one hand, method on the other hand) in principle, one after the other or simultaneously. However, in this case, it is conceivable to additionally rotate the main arm in order to produce an 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 a plurality of plate-shaped objects, each of which is placed in each case on a single auxiliary arm, can be rotated independently by each of the additional arms is rotated according to 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 rotating device - rotated in this case by rotation of the additional arms about the respective second axis of rotation - correspondingly and proceed linearly with the funding, these steps (turning one hand, method on the other hand) usually in a suitable sequence one after the other and possibly iteratively. In this case too, it is conceivable to additionally rotate the main arm in order to produce an additional movement of the plate-shaped objects, in particular if the plate-shaped objects are arranged eccentrically to the first axis of rotation. Accordingly, this additional movement can be included in the said sequence of movements (rotation and procedure).

In particular, to be able to align suitable small plate-shaped objects, it is provided in a preferred embodiment of the Zustelltisches invention 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, a rectangular glass plate of 0.3 m to 1.3 m in length and 0.3 m to 1.3 m in width can be easily manipulated and exactly fed to the processing device in this way.

Again, the plate-shaped object is supplied with the conveying means of the rotating device and with the rotating device - in this case by rotation of the turntable about the third axis of rotation - rotated accordingly and preferably also linear, these steps (turning 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 rotate the main arm and / or the additional arm on which the turntable is rotatably mounted to produce an additional movement of the plate-shaped object, especially if the plate-shaped object eccentric to the first axis of rotation and / or second axis of rotation is arranged. 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 turntable that a plurality of plate-shaped objects, each of which is placed each on a single turntable, can be rotated independently by each of the turntable is rotated according to its third axis of rotation. That Preferably, the turntables can be rotated independently of each other about their third axis of rotation.

Again, the plate-shaped objects are supplied to the conveying means of the rotating device and with the rotating device - in this case by rotation of the turntable about the respective third axis of rotation - rotated accordingly and preferably also proceeded according linear, these steps (turning one hand, method on the other ) in principle, one after the other or simultaneously. In this case too, it is conceivable to additionally rotate the main arm and / or the at least one additional arm in order to generate additional movement of the plate-shaped objects, in particular if 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 turntable 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, this is preferably lifted after being fed by the conveying means of these by means of the rotating device and remains raised during the entire movement with the rotating device. It is sufficient if the plate-shaped object is only slightly lifted off the conveyor, e.g. a few centimeters, typically 3 cm to 7 cm, especially 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 regard to the design effort and the associated costs on the one hand, and the workable size range of the plate-shaped objects to be moved on the other hand.

In a preferred embodiment of the Zustelltisches invention, it is provided that exactly two turntable are provided for each additional arm. This, too, represents in practice a mostly optimal compromise with regard to the design effort and the associated costs, on the one hand, and the workable size spectrum of the plate-shaped objects to be moved, on the other hand. In particular, a secure support for large plate-shaped objects is made possible by two turntables per additional arm.

In particular, in the case of medium and small plate-shaped objects, it is sometimes not absolutely necessary to allow the at least one additional arm to protrude at an angle from the main arm in order to enable the most stable possible support or support of the plate-shaped object. In this case, the rotating device can be arranged to save space. Therefore, it is provided in a preferred embodiment of the Zustelltisches invention that in a zero position, a longitudinal axis of each additional arm parallel, and preferably congruent, extending to a longitudinal axis of the main arm.

It should be noted, however, that in general an optimal adaptation of the rotating device to the geometry of the plate-shaped object is possible by appropriate 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 in a range of 5 ° to 30 °, relative to the main arm to allow optimal support of a long narrow plate-shaped object. With several additional arms, it would also be conceivable that not all, but only one of the additional arms or some selected additional arms include such an angle with the main arm and the remaining additional arms are aligned parallel to the main arm. In particular, 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, however, 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 rotating device particularly space-saving especially for small plate-shaped objects, it is provided in a particularly preferred embodiment of the Zustelltisches invention that extends in the neutral position, 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 the second direction and / or the third direction. On the one hand, this allows a certain process of the plate-shaped object to be made parallel to the first direction, without the need for the conveying means to be used for this purpose. In this way, the plate-shaped object can be time-saving and extremely precise linear move.

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 parallel to the second direction forcibly by other means than the rotating device would have to be done.

The ability to move the plate-shaped object by means of the rotating device also parallel to the third direction, provides a simple way to decouple the plate-shaped object from the funding, in particular by the plate-shaped object is simply lifted by means of the rotating device of the funding upwards , Conversely, of course, the rotating 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, especially on the funding. That In this way the coupling to the conveying means could be (re) established.

In order to move the entire rotating 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. This movement preferably takes place along the first axis of rotation.

In particular, if medium-sized plate-shaped objects to be lifted from the linear funding, rotated and possibly placed on this again, sometimes an additional arm is large enough to ensure complete support and safe resting 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. In order to make this possible, it is provided in a preferred embodiment of the Zustelltisches invention 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 to be lifted from the linear funding, rotated and placed on these again, sometimes a turntable is large enough to ensure complete support and safe resting of the plate-shaped object. That In this case, only the respective turntable must 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 provided in a preferred embodiment of the Zustelltisches invention that the at least one turntable is movable parallel to the third direction relative to at least one additional arm. This movement preferably takes place along the respective third axis of rotation.

Basically, a large number of possibilities for the realization of suitable linear conveying means known from the prior art, for example chain conveyors on which the plate-shaped object rests, or an air cushion combined with finger conveyors that push the plate-shaped object on the air cushion. In order to achieve a structurally simple, precise and reliable realization of suitable conveying means, it is provided in a preferred embodiment of the Zustelltisches invention that the conveying means comprise at least one, preferably 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 suction devices.

On the one hand to guarantee a stable position of the plate-shaped object in the straight-line promotion means of the conveyor or belt conveyor and on the other hand to ensure the most balanced arrangement of the plate-shaped object on the rotating device during rotation with this, it is in a particularly preferred embodiment of the invention Zustelltisches provided 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 provided in a preferred embodiment of the Zustelltisches invention that the conveying means are movable parallel to the second direction. Preferably, each conveyor, in particular each belt conveyor, may be individually movable parallel to the second direction, i. independent of another conveyor, in particular other belt conveyors. In the case of the rotary device arranged between two conveying means or belt conveyors, the belt conveyors can also be moved together with the rotating device parallel to the second direction, without the rotating device abutting one of the belt conveyors.

On the one hand to ensure a stable promotion plate-shaped objects of various sizes by means of belt conveyors and on the other hand always to ensure the most balanced arrangement of the plate-shaped object on the rotating device during rotation with this, it is provided in a particularly preferred embodiment of the Zustelltisches invention that the two belt conveyors, between which the rotary device is arranged, are movable parallel to the second direction towards and away from each other. 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 supplying plate-shaped objects of a processing device, in particular for coating, in a highly precise and effective manner. Accordingly, according to the invention a use of a Zustelltisches invention for feeding the plate-shaped object to a processing device for processing, preferably coating, in particular an edge, the plate-shaped object is provided.

The precise processing or coating of edge regions of plate-shaped objects is an increasingly frequent 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 other plate-shaped objects are possible, especially if they have a closed smooth surface to allow effective suction.

In particular, if the delivery table according to the invention for the delivery of frame profiles, such. Window frame is used, it is advantageous to run 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.

Therefore, it is provided in a preferred embodiment of the Zustelltisches invention that the at least one turntable is designed as a sucker and / or gripper. That It is also possible a combination in which some turntable as a vacuum cleaner, other turntable are designed as a gripper. It would also be conceivable, however, for a turntable to have both a suction function and a gripping function. In particular, when the plate-shaped object is raised with the rotating device, this enables a stable position of the plate-shaped object on the rotating device.

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, the glass plate 2 is executed square with a side length of typically 2.7 m.

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

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 in dashed lines in a position in which it is brought to the Zustelltisch 1 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 with this 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 the three directions 4, 5, 6 are mutually normal to each other.

In order to align the glass plate 2 for the coating as desired relative to the processing device 8, the Zustelltisch 1 next to the belt conveyors 3a, 3b, a rotating device 7, by means of which the glass plate 2 are rotated about a direction parallel to the third direction 6 axis of rotation can.

For this purpose, the rotary device 7 has a main arm 9, which is rotatable about a first axis of rotation 12, preferably by means of an electric motor 21, cf. 2. The first 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, two additional arms 10a, 10b are mounted rotatably about second pivot axes 13a, 13b on the main arm 9, wherein the second pivot axes 13a, 13b are parallel to the third direction 6. The second axes of rotation 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 is in each case a turntable 11a, 11b, 11c, 11d on the respective additional arm 10a, 10b rotatably mounted about third axes of rotation 14a, 14b, 14c, 14d, which are parallel to the third direction 6 are.

I. E. the additional arm 10a has the turntables 11a, 11b with the third axes of rotation 14a, 14b and the additional arm 10b the turntables 11c, 11d with the third axes of rotation 14c, 14d. The turntables 11a, 11b, 11c, 11d can preferably be rotated by means of electric motors 21 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 have a right angle. In this way, the rotating device 7 covers a large area, and large plate-shaped objects or glass plates 2 can be easily accommodated or supported by the rotating device 7 and moved without the risk that the respective glass plate 2 out of balance and from the rotating device 7 tilts down.

The recording of the resting on the belt conveyors 3a, 3b glass plate 2 on the rotating device 7 is carried out by moving the rotating device 7 in the third direction 6. As a result, the glass plate 2 is first contacted by the turntables 11a, 11b, 11c, 11d and then lifted from the belt conveyors 3a, 3b, ie decoupled from the belt conveyors 3a, 3b. Preferably, the turntables 11a, 11b, 11c, 11d are formed 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 , guided, cf. 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 is in engagement with a rack (not shown). In principle, however, could e.g. Also, at least one pneumatic, hydraulic or electric cylinder for moving the rotary device 7 and the main arm 9 may be provided parallel to the third direction 6.

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. 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 or small glass plate 2 which is supported only on one or both turntables 11a, 11b; 11c, 11d of a single auxiliary arm 10a; 10b rests to turn. Typically, the dimensions of a medium glass plate 2 lying on both turntables 11a, 11b; 11c, 11d 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 resting on a single one of the turntables 11a, 11b, 11c, 11d are typically in the range of 0.4m to 1.25m in length and 0.4m to 1.25m in width.

Finally, in Fig. 3, a rotation angle γ is shown, by which the turntables 11a, 11b, 11c, 11d can be rotated about the respective third axes of rotation 14a, 14b, 14c, 14d to a small glass plate 2, the only on one of the turntables 11a, 11b, 11c, 11 r rests to rotate. The angles of rotation β and γ can each 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 angles of rotation β and γ each cover 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, these are still supported by the rotating device 7 and fixed by means of the turntable 11a, 11b, 11c, 11d designed as a sucker.

Theoretically, it would also be conceivable, the glass plate 2 by lowering back 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 turntables 11 a, 11 b, 11 c, 11 d no longer touch the glass plate 2, wherein the suction would be disabled.

Preferably, each of the additional arms 10a, 10b and each of the turntables 11a, 11b, 11c, 11d can be moved individually parallel to the third direction 6, for example by means of a 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 is in turn guided linearly by means of a rail 18 which runs parallel to the first direction 4. That 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 an electric motor 21 in a conventional manner, for example by the electric motor 21 a pinion (not shown) drives, which (not shown) with a rack engaged. Thus, the glass plate 2, when it rests on the rotary device 7 and on the turntables 11 a, 11 b, 11 c, 11 d is raised and moved very precisely and quickly linearly parallel to the first direction 4, without the need for 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 transverse to the first direction 4 transverse bar 23, which in turn is guided at its ends in rails 19, which are parallel to the second direction 5, out. 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 rotary device 7 and on the turntables 11 a, 11 b, 11 c, 11 d and is raised, very precise and quickly linearly parallel to the second direction 5, are moved.

Fig. 4 illustrates a situation in which the glass plate 2 on lying on the Drehvorrich-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 procedure is. 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 connected to further transverse to the first direction 4 transverse beams 24a, 24b. 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 FIG Second direction 5 seen can be kept substantially constant.

Theoretically, the glass plate 2, if it rests on the belt conveyors 3a, 3b, could be conveyed with these not only parallel to the first direction 4, but also parallel to the second direction 5, without necessarily for this purpose the rotating device 7 must be used.

Finally, the belt conveyors 3a, 3b can also be moved toward and away from each other parallel to the second direction 5 if no glass plate 2 (or no plate-shaped object) rests on the belt conveyors 3a, 3b. In this way, a measured parallel to the second direction 5 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 3a, 3b can be reduced only as far as it allows the spatial extent of the rotating device 7 in the second direction 5, in particular if the glass plate 2 continues to be rotated with the rotating 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 extent 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. 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 smallest possible extent of the rotating device 7 in the second direction 5 is given, however, when the longitudinal axes 16, 17 a, 17 b are parallel to the first direction 4. This zero position 15 is illustrated in FIG. 5.

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 on the belt conveyors 3a, 3b a survives little. 5, the glass plate 2 is shown in broken lines in a position from which it is brought to the Zustelltisch 1 parallel to, more precisely opposite, the first direction 4, wherein the arrow illustrates the movement without reference character in the approach.

Lying on the two belt conveyors 3a, 3b, the glass plate 2 can then be moved parallel to the first direction 4 by means of the belt conveyors 3a, 3b, in particular to one of the turntables 11a, 11b, 11c, 11d, in Fig. 5th the glass plate 2 is shown above the turntable 11 d. If necessary, in addition, the rotating device 7 and thus the

Turntable 11 d are moved parallel to the first direction 4 so until the turntable 11 d is centrally located under the glass plate 2 and this can safely accommodate. For a rotation of the glass plate 2, this can therefore be raised by moving the rotating device 7 or the turntable 11 d alone in the third direction 6, until the glass plate 2 rests only on the turntable 11 d and is supported by this. Preferably, the glass plate 2 is fixed by suction on the trained as a sucker turntable 11 d. Then, the turntable 11 d can be rotated about its third axis of rotation 14 d by the desired angle γ in order to achieve the desired orientation of the glass plate 2.

It is understood that in this case, the rotating device 7 can be moved parallel to the first direction 4 to move the resting on the turntable 11 d glass plate 2 parallel to the first direction 4. Furthermore, in this case as well, the rotating device 7 can be moved together with the belt conveyors 3 a, 3 b parallel to the second direction 5 in order to move the glass plate 2 resting on the turntable 11 d parallel to the second direction 5.

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

As already mentioned, the rotating device 7 can be adapted to the geometry of the respective glass plate 2 to be moved and aligned by rotating 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, a typical alignment process will be described with reference to FIG. 1, as it may occur in a circumferential coating of the edge of the glass plate 2. After the glass plate 2 by means of the belt conveyors 3 a, 3 b of the rotating device 7 was supplied and lifted by the rotating device 7 and rests only on the turntables 11 a, 11 b, 11 c, 11 d, 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, closes off the glass plate 2. 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 rotated by the corresponding amount, 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 reference line 27 which is parallel to the second direction 5. Now the glass plate 2 is moved against the first direction 4 to 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 are completely known, and may be indicated 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 can be chosen so that there is a strip to be coated with a desired width in the second direction 5, when the first edge 31 of the glass plate 2 to coincide with the first Reference line 26 is brought. Likewise, the position of the second reference line 27 may be selected so that a strip to be coated with 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 covering of the first edge 31 with the first reference line 26 and the covering of the second edge 32 with the second reference line 27 can be achieved by moving the rotating device 7 parallel to the second direction 5 and the first direction 4, so that the glass plate 2 with respect the first direction 4 and the second direction 5 is now positioned in a coating position. Possibly. For example, the belt conveyors 3a, 3b must be 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 be lowered by moving the rotating device 7 counter to the third direction 6, so that the edge to be coated in the region of the first edge 31 and second edge 32 of the glass plate 2 rests on the processing device 8 to perform the coating can. Preferably, the glass plate 2 is further supported by the rotating device 7 and fixed by means of the turntables 11a, 11b, 11c, 11d designed as suction elements.

After coating, the glass plate 2 can be raised again by means of the rotating device 7 and brought by methods parallel to the first direction 4 and the second direction 5 in 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 exactly known, the glass plate 2 can be moved and rotated 180 ° after rotation directly in the coating position 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, where it is e.g. Can be lifted by a crane from the Drehvorrich-device 7. Theoretically, however, it would also be possible to lower the glass plate 2 onto the belt conveyors 3a, 3b and to convey with them the glass plate 2 away from the infeed table 1, which, however, is usually much more time-consuming in practice.

Finally, it should be noted that the to be processed, preferably coating, plate-shaped object or the glass plate 2 need not necessarily be rectangular, but, for. can also be triangular or otherwise 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.
