The invention relates to a lifting and deburring device for folding tile turret presses with a Suction head and a knife frame surrounding it and displaceable with respect to the suction head.

In the production of interlocking tiles, the tile that is pressed in a turret press is usually finished Bricks deburred using a knife frame, then released from the lower mold and placed on a wooden frame filed. A known device in which the knife frame is used to mechanize this operation and a lifting device that works by means of negative pressure, hereinafter referred to as the suction head, are united. To the brick reliably from, cut off Burrs need to be separated from the suction head when the knife frame sits on the lower mold fetched back through this and then put down.

The invention is based on the object in a lifting and deburring device of the initially mentioned type a sticking of the brick on the knife frame and a soiling of the knife avoid.

This object is achieved in that the suction head retracted into the knife frame during deburring for the purpose of laying down the brick from which the frame is arranged so that it can be extended from the front.

This mutual mobility of the suction head and knife frame reliably prevents contamination the knife and the brick from getting caught on them. The deburred brick is completely free on its circumference after the suction head has been extended out of the knife frame can be placed on its frame without hindrance, which, as is known, can be done with the help of can take place by compressed air blown between the suction plate and the brick.

In order to keep the knife clean, it is useful if the sliding and guide surfaces for the knife frame with lubricant on the suction head:, preferably a compressed air-oil mixture, supplying device is provided.

In the drawing is an embodiment of the lifting and deburring device according to the invention shown. It shows

F i g. 1 is a view of a section through the device with the suction head extended,

FIG. 2 shows a representation corresponding to FIG. 1, in which the suction head is retracted and the knife frame is in the deburring position.

On the underside of a lifting plate labeled 10, the drive device of which is not shown, sits the lifting and deburring device acted upon on both sides

Piston provided and operated by compressed air piston-cylinder drive 11 and 12 for the movable suction head 13. Hollow bolts 14, 15 fastened in the lifting plate are used to guide it. The bore of the bolt 14 is connected to a vacuum source, that of the bolt 15 with a compressed air source in order to obtain a vacuum in the cavity 13 α of the suction head when the brick is lifted from the lower mold 16 and an overpressure when the brick is pushed off the suction head. (Suction heads for ejecting the bricks with compressed air are known per se and therefore do not need a detailed description here.) A knife frame 18 with cutting edge 18 α is attached to the lifting plate 10 with the interposition of electrical insulation 17. It fully surrounds the suction head 13, which is fitted with wear sealing strips 19 on its circumference. In their sliding surfaces, channels 19 α running transversely to the feed direction are incorporated, to which a compressed air-oil mixture is fed via bores 19 & from channels 13 & in the suction head. The supply lines through which the compressed air-oil mixture reaches the channels 13 b and the guide surfaces 21 for the hollow pin 15 (FIG. 2) are denoted by 20 and 22.

The suction head 13 can be removed from the knife frame IS by means of the piston-cylinder drive 11, 12 are extended (Fig. 1), and so far until the vacuum effect on the suction head hanging bricks is completely free from the knife frame on its entire circumference, or can be retracted (Fig. 2), so that the knife frame still pressed in the previous work stage can deburr connected brick with its press burr. The brick is (F i g. 2) for Part still in the lower mold, and the knife

At the end of its downward movement, the box arrives with its cutting edge 18 α to sit on the steel strip 23. The cut ridge is denoted by 24. The device works in such a way that the suction head 13 is retracted into the knife frame 18 and the whole device is lowered until the knife frame rests with its cutting edge 18 α on the deburring bar23, ie has cut the burr from the compact and also has the suction plate fed up on the Pressing rests. The vacuum valve (not shown) is now opened and the cavity 13 α of the suction head is connected to the vacuum source via the bore in the hollow pin 14. The lifting device is now raised as a whole, and the release of the compact from the lower mold 16 can be assisted in a manner known per se by blowing in compressed air. When it is lifted, the device performs a lateral pivoting movement away from the press in order to get ao via a conveyor belt or the like, which brings the wooden frames to and from the press. When the set-down position is reached, the suction head 13 is extended out of the knife frame (in FIG. 1) until the brick is completely free from the knife frame 18 on its periphery. During this mutual movement of the suction head 13 and knife frame 18, the knives are lubricated on the inside with the oil mist supplied through the channels 19 α and at the same time cleaned of clinging clay. The suction head is now switched to compressed air, which is fed to the cavity 13 a through the bore of the hollow pin 15. The brick is thereby released from the suction plate and placed on the frame. The air valves are operated electromagnetically; A program control unit is provided on the press to control it. Patent claims: 1. Lifting and deburring device for interlocking tile revolver presses with a suction head and a knife frame encompassing this and displaceable with respect to the suction head, thereby characterized in that the suction head retracted into the knife frame during deburring for the purpose of laying down the brick is arranged so that it can be extended forward from the frame. 2. Lifting and deburring device according to claim 1, characterized in that the suction head one of the sliding and guiding surfaces for the knife frame with lubricant, preferably a compressed air-oil mixture, supplying device is provided.
