Definitions
- the invention relates to a lifting and deburring device for interlocking brick turret presses with a lifting plate, a suction plate and a knife frame surrounding the suction plate, the suction plate and knife frame being movable relative to one another.
- the knife frame is firmly connected to the lifting plate, which in turn is firmly connected to the press.
- the suction plate is pneumatically inserted into the knife frame for pressing and deburring a ceramic tile.
- a vacuum is then applied to the suction plate in order to be able to lift the pressed and deburred interlocking tile from the associated lower mold.
- the suction plate is pressurized with compressed air and at the same time extended out of the knife frame.
- the invention has for its object to provide a device of the type described above, which ensures proper cleaning of the knives of the knife box and gentle storage of the interlocking tile moldings.
- suction plate is fixed to the lifting plate and thus immovably connected to it, and that the knife frame is extendable and retractable relative to the suction plate.
- the knife frame in the area of the knife edges is advantageously slidably arranged on an oiled felt insert arranged on the circumference of the suction plate such that the knife edges can be retracted over the lower edge of the felt insert.
- the knives of the knife box are constantly oiled through the oiled felt insert in contact with them and any clay residues still adhering to them are stripped off when the knife frame is pulled back relative to the suction plate.
- the interlocking tile blank is put down, it is released from the suction plate by releasing the vacuum and additional compressed air supply in a reliable and gentle manner, without the suction plate moving relative to the lifting plate connected to the press.
- the knife frame is advantageously guided such that it can be moved relative to the suction plate by means of rod guide bearings, four rod guide bearings being expediently provided.
- the guide function is thus exclusively assigned to the rod guide bearings in connection with the felt insert, and guidance via the extension drive is neither required nor provided.
- a compressed air cylinder arrangement for extending and retracting the knife frame is expediently arranged between the suction plate and the knife frame.
- the compressed air cylinder arrangement advantageously consists of two compressed air piston cylinders which, as already mentioned, do not have to perform any guiding functions and can accordingly be of simple and robust design.
- the extension and retraction drive of the knife frame can advantageously be controlled separately from the operating pneumatics of the suction plate.
- the relative movement between the knife frame and the suction plate can be controlled separately depending on the operational requirements and independently of the actual laying process of the interlocking tile blank.
- suction plate and the knife frame are expediently arranged electrically insulated from one another in order to be able to apply direct voltages of different polarities to the two parts in order to improve the detachment of clay.
- the preferred embodiment of the lifting and deburring device according to the invention shown in the drawing also referred to as a suction head, has a lifting plate 1 and a suction plate 2 attached to it.
- a vacuum connection 3 and a compressed air connection 4 are provided in the upper part of the hollow suction plate.
- the underside of the suction plate 2 has suction bores 5 towards the interlocking tile blank 6.
- the suction plate 2 is surrounded by a knife frame 7 which is movable relative to the latter.
- the knife frame 7 can be extended by means of two compressed air piston cylinders 8 in a controlled manner from the position shown in FIG. 1 relative to the suction plate 2 into the position shown in FIG. 2 and can be withdrawn from this again into the position according to FIG. 1.
- the knife frame 7 is guided relative to the suction plate 2 by means of four rod guide bearings 9 which slide onto the bolts 10 connecting the lifting plate 1 and the suction plate 2.
- a felt insert 11 is attached, on which the knife 12 of the knife frame 7 slide.
- holes are provided in the side walls of the suction plate, which are supplied by a central oil connection for constant or intermittent oiling of the felt insert 11.
- the knives 12 of the knife frame 7 are electrically insulated from the suction plate 2 by an insulating insert 14. By applying direct voltages of opposite polarities to the suction plate 2 on the one hand and the knives 12 on the other hand, the cleaning effect on the knives 12 can be further improved.
- the extension and retraction drive of the knife frame 7 can be controlled separately from the operating pneumatics of the suction plate 2.
- the movement of the knife frame 7 can be controlled independently of the actuation of the operating pneumatics of the suction plate 2 and adapted to the respective most favorable conditions for sucking and depositing the interlocking tile blank 6.
