DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device for receiving and transposing of plates, in particular glass plates from a substantially vertical position into a substantially horizontal position, or in reverse, with a pivot arm which is pivotable around a horizontal axis into two end positions, namely into a receiving position and into a release position and back, whereby at the pivotable end of this horizontal axis, a support arm is pivotably mounted around a horizontal axis which is provided with suction cups for receiving a plate and which is so guided that it is moved at an angle around its pivot axis which is smaller than 90.degree. during the movement of the pivot arm from an end position into the other position.
Devices of this type are known, for example, from prospectuses of the company Grenzebach. The known devices are provided with special drives which operate the rotating of the support frame during the pivot movement of the pivot arm. The rotating drive for the support frame can be derived from cam disks and transmitted through chains onto gears which are mounted on the pivot axis of the support frame.
The known devices are disadvantageous in that the pivot drives for the support frame are relatively expensive and subject to interferences and that appearances of wear show after a long operation duration which make an exact guiding of the support frame questionable.
It is an object of the subject invention to design a device for receiving and transposing of plates, in particular, glass plates of the aforementioned type, in such a manner that after a long operation time it still operates exactly and reliably, while being of simple construction. Such a robust structure is obtained in accordance with the invention in that the support frame is rigidly connected with a guide rod which is positioned in a vertical plane and which is guided longitudinally displaceable in a guide bushing which is pivotably mounted around a horizontal axis outside of the pivot radius of the pivot arm. This device in accordance with the invention has the advantageous that the support frame is pivoted into the desired position by the guide rod during pivoting the pivot arm from the receiving position into the release position. Since the guide bushing can be located at a relative large distance from the pivot radius of the pivot arm and therefore also in a relative large distance from the pivot axis of the support frame, the guiding forces which act on the guide bushing and the guide rod are low.
Advantageously, the rotating axis of the pivot arm and the pivot axis of the guide bushing are so disposed, and the radius of the pivot radius, the pivot angle of the pivot arm as well as the angle between the plane of the support frame and the guide rod are so coordinated to the receiving position and release position of the plates, that the guide rod is disposed substantially at a right angle with respect to the pivot arm in the end positions of the pivot arm. This embodiment has the considerable advantage that the rotating movement of the support frame in the end positions of the pivot arm is at a minimum, so that, for example, the horizontal end position of the support frame can be adjusted, with limits, to the transport height of the feeding device, and that the position of the support frame in the almost vertical position can be adjusted to the pile.
Further features of the invention are stated in the claims.
The invention is explained in the following description with respect to the drawings which show exemplified embodiments.
The drawings show:
FIG. 1 a side view and
FIG. 2 a front view of the device in accordance with the invention,
FIG. 3 a front view of a modified exemplified embodiment of the device in accordance with the invention.
The device shown in FIG. 1 serves to receive substantially horizontally fed glass plates 2 from feeding device 1, for example, a conveyor or roller train and to place them onto a glass support 3 which retains the placed glass plates in a position which is somewhat inclined from a vertical position.
