Description

Device for unloading ceramic plates from a Hagen

The invention relates to a device for unloading IQ ceramic plates from a trolley according to the preamble of claim 1.

Make the burn have to stand on their narrow sides Ceramic plates are unloaded from the kiln car and conveyed on flat for reasons of stability and for inspection for sorting and packaging.

It is known / manually unloading plates set standing on their narrow sides or over them in rows to pick up their narrow sides, to move them and to tilt them during further transport.

Manual unloading is labor-intensive and leads to increased damage to the plates; in rows Rarely, tapping requires sufficient and constant spacing between the transverse rows for inserting the gripper. In addition, for reasons of stability, the plates must be placed on the device that is demanding further must first be compacted, whereby damage is possible.

The invention is therefore based on the object of automatically unloading plates standing on their narrow sides, placed in rows on Hagen and thereby removing the plates

One should be placed flat on the conveying device.

This object is achieved according to the invention by the measures indicated in the characterizing part of claim 1 solved"

The advantages that can be achieved with the invention exist especially in that / that the plates are automatically picked up individually and gently on the further conveyor and that no specific spacing is required between the transverse rows of panels on the carriage.

An exemplary embodiment of the invention is shown in the drawing and is described in more detail below. Show it:

plates 1 , which stand with or without a distance between the transverse rows 2, normally in several layers one above the other in the same orientation on the carriage 3, the layers being separated from one another by intermediate plates 4, which are unloaded with a separate device (not shown), are tapped with an Eat charger 5 from the car 3 and for further processing

fed to a further conveyor 6. The plates 1 one or more transverse rows 2 can be the same " can be picked up and transported on in good time. The unloading device 5 is at the level of the top -

B plates 1 on the carriage 3 in direction Ά) over the carriage and each time after the last plate has been unloaded 1 in a transverse row 2 against the direction A) brought back to the starting position.

The unloading device 5 has a row of suction grippers 9 mounted on a shaft 7 with a rotary drive 8 / which are brought into contact with the plates 1 standing on their narrow sides on the carriage 3, wherein the suction pads 9 contain elastic members 10, so that differences in the position of the plates 1 on the Car 3 can be compensated within limits. The unloading device 5 also contains a suction pad between the suction grippers entering raisable and lowerable conveyor 11 made of narrow sanders or chains.

After a foremost plate in a row has been picked up, the suction grippers 9 are moved by the shaft 7 Pivoted upwards by 90 °, whereby they come into engagement with the conveyor 11 which can be raised and lowered. The plat ten 1 become after briefly switching off the vacuum and tremors of the conveyor 11 taken over by this. With the lifting and lowerable conveyor 11, the plates 1 in direction B) Transferred to the following conveyor 6, while the suction gripper 9 swivels back into its starting position and the discharge device 5 in the direction A) until the contact is moved on with new plates 1.
