Abstract

A method and device for conveying large-area panels, particularly panes of glass, of extreme size over 40 meters long and over 6 meters wide, wherein the panel can be held from the bath side or the air side, said method comprising the following features: a) the panes of glass (10) delivered on conveyance rollers (17) are swung by means of a vertical hoisting device (20) either on the left side or right side at an acute angle, wherein the device (20) has finger-like carrying elements structured in a comb arrangement which grip through the conveyance rollers (17) and carry suction discs (12); b) swung in this way, the pane of glass (10) is gripped by means of a plurality of comb grippers (22) using suction discs (12), which grippers are synchronized in their sequence of movements, and placed on a stacking frame (15, 16), wherein the comb grippers (22) are moved on a plurality of guiding beams (2) arranged like a portal.

First claim

The invention claimed is:

1. An apparatus for conveying glass panels, comprising the following features:
a conveying line which is fitted with conveying rollers;
a plurality of portal supports which are arranged in a linear manner one behind the other and are connected by means of guide beams and support column carriages;
a plurality of comb-type grippers which are positioned by means of a pivoting and rotating device in a manner in which they are each moved horizontally on the guide beams by means of a column carriage and are vertically guided by a lifting column, wherein the comb-type grippers are fitted with suction devices, and wherein each comb-type gripper can change the width of its capture range on both sides by means of a telescopic apparatus;
a stacking framework for setting down a glass panel such that it is inclined to the left and/or a stacking framework for setting down a glass panel such that it is inclined to the right, wherein glass panels of about 40 meters in length and about 6 meters in width are conveyed, wherein the panels can be held from the bath side or from the air side,
a vertical-lifting apparatus is provided in the length and the width of the respective panel, wherein said vertical-lifting apparatus can be pivoted at an angle of up to 90 degrees such that it is stopped on the left and/or right side,
distance sensors to control the movement of the individual comb-type grippers, and,
wherein extendable stabilizers are additionally provided on the corresponding column carriages, and wherein laser sensors are used to align the comb-type grippers with one another vertically and horizontally, and wherein, in order to control the entire conveying system, field sensors are installed on each portal support, said field sensors being aligned with one another and, in the form of hundreds of mini lenses, collecting optical information in accordance with the optical field principle, it then being possible for said optical information to later be combined using data technology to form images with a desired resolution and/or a desired viewing angle.

2. An apparatus according to claim 1 , wherein power suction devices and/or precision suction devices are used on the vertical-lifting apparatus and/or on the comb-type grippers, wherein a power suction device has a circular filter element and the flow resistance of a filter element is detected and displayed on a monitor, and wherein a precision suction device has a sealing ring which is guided in a suction device head which is composed of solid material.

3. An apparatus according to claim 1 , wherein electrostatic grippers and/or ultrasonic grippers are used for conveying purposes on the air side in the case of glass panels which are to be coated.

4. A method for conveying glass panels comprising the following features:
delivering glass panels on conveying rollers;
capturing the glass panels by means of suction devices on a large number of guide beams, the beams forming a portal, by means of a large number of comb-type grippers, of which the movement sequences are synchronized, and set down on a stacking framework in a desired location, wherein the comb-type grippers are moved on the large number of guide beams and wherein each comb-type gripper can change the width of its capture region on both sides by means of a telescopic apparatus, wherein glass panels of about 40 meters in length and about 6 meters in width are conveyed, wherein said panels can be held from the bath side or from the air side, the glass panels, which are delivered on conveying rollers, are pivoted at an acute to right angle either on the left or the right side as required by means of a vertical-lifting apparatus which extends over the entire length of the glass panel,
controlling the movement of individual comb-type grippers using distance sensors,
wherein extendable stabilizers are additionally provided on the corresponding column carriages, and wherein laser sensors are used to align the comb-type grippers with one another vertically and horizontally, wherein, in order to control the entire conveying system, field sensors are installed on each portal support, said field sensors being aligned with one another and, in the form of hundreds of mini lenses, collecting optical information in accordance with the optical field principle, it then being possible for said optical information to later be combined using data technology to form images with a desired resolution and/or a desired viewing angle.

5. The method according to claim 4 , wherein power suction devices and/or precision suction devices are used on the vertical-lifting apparatus and/or on the comb-type grippers, wherein a power suction device has a circular filter element and the flow resistance of a filter element is detected and displayed on a monitor, and wherein a precision suction device has a sealing ring which is guided in a suction device head which is composed of solid material.

6. The method according to claim 4 , wherein electrostatic grippers and/or ultrasonic grippers are used for conveying purposes on the air side in the case of glass panels which are to be coated.

7. The method according to claim 4 , wherein the comb-type grippers and the vertical-lifting apparatus are employed separately.
