Ausiührungsiorm the invention is the plate in this Position held during several successive stripping processes and after each stripping process lowered as much as it corresponds to the thickness of a tile.

According to a further embodiment of the invention several tiles successively on conventional ■> -:. Manner and with conventional devices onto the surface of a shovel or other conventional means are stripped to pick up stripped tiles, taken individually after stripping, in order one after the other still in the fresh state on top of one another on the moving Plate and to be transported in this way in the stacked state to the drying cell. This Operation can be achieved in that the ordinary scraper with one among the raised took insertable shovel connected to a transfer tool with which the fresh tile is transported from this shovel to the plate on which several fresh Tiles are to be stacked. This tool can be in the form of a suction device with suitable storage means and be designed with protective and support bars provided therein for the tile on which the negative pressure acts.

A plate with several rows of superimposed Tiles can be moved directly into the drying cell and other processing facilities.

Fig. 1 shows the conventional stripping system. The frame is raised after the pressing process with respect to the bottom of the mold, so that the tile M remains in the frame. One Shovel with a plate 13 or other member for receiving the stripped tile is placed directly under the Frame 11, and then the stripping with the help of a Stamp 15 causes the stripping of the tile M by the effect of its relative movement in relation to

609882/0368

determines the frame 11; usually stays with Ausreifvorgaug the stamp becomes stationary and the rooms raked on, while the loosened tile remains on the plate 13 or the like. The plate or the like Means is then moved away according to deui Pieii 11.

Cremuli of a first embodiment of the inventive method are opened after a first removal process! a plate ± j which the latter together with the shovel does not move away, but ledigiicii closed in such a way that the upper surface of the first stripped tile Mi serves to receive the second tile M2, which is stripped by the following frame, which is attached to para Treif station uiiCome. The process can continue

on
lunrt that the two tiles Ml and M2 a third filament Mj, which is then stripped, is stacked, the plate 1} being lowered even further beforehand. The same process can be extended further by slipping off a fourth tile M'i, a controlled lowering of the shovel or other member and the plate can be provided for each subsequent lowering, or it can even be arranged that the lowering is carried out directly a near downward movement of the stripping element such as, for example, yy. of the punch 15 is effected. After a certain number of stripping processes and therefore of Aufemauderstapelungen new tiles, the plate is separated in order to be used for subsequent treatment, e.g. B. to the drying cells to be moved on.

Most of the controls are hydraulic.

of the seven plates! Each shape includes a floor I ¹ J and a room 21 similar to your 11 denotes tea and can e.g. B. by means of a vertical hydraulic cylinder-piston system 23 are lifted and abseukt. From a stationary structure 24 on the stripping part a punch 25 is carried (which is the punch Ij eutspricut ), which is operated by a cylinder-piston system 2o, 2oA, which is controlled for a preliminary lowering by a limit switch 25A, which is to be stripped Tile felt.

in station 1 the frame 21 descends on the floor 19 and the first layer of mortar is poured in; in station 2 there is a shaking run; in station J it is planned to distribute the second shift; A first pressing or pre- pressing is provided in station and a second pressing is provided in station j , which is achieved with a press, the type of which is indicated at 27. In station b (see also FIG. 4) the lifting of the frame 21 from the supported arrangement on the floor 19 to the raised arrangement shown in FIG. 4 is provided. In the stripping station / a movable carriage is arranged in addition to the stationary structure 24, which can be moved along guides 31 which are aligned radially with respect to the table 1 /; the carriage 29 is moved with the aid of a cylinder Koiberi system. The carriage 29 carries a paddle member 33 which is guided for vertical movement with respect to the carriage 29 by means of a cylinder-piston system Jk; This system 34 includes a controller 35 ₅ which is formed so as to cause the Anhebaa of the blade and a series of partial lowering of the same permitted by an action from the outside and following it, stopping the blade on each level achieved. A plate 3'j is shown on the shovel 33 which corresponds to the plate 13 iu of the preceding Dars teii "ü; igea. When the carriage 29 is brought close to the press (Fig. 4 & cä 5) the plate 3 ^f J • -inter of the frame 21, egg is lifted, while uacii deia removing the Wageas 29 according to the arrow f3 (Pig = ο)

the plate 3b with melirereu stripped and stacked tiles can be dispensed with. In the arrangement for the outside of the tiles (Fig. ¹ i and 5) the unit _>3> ^ b is lowered lortscnreitend. For this purpose a cylinder-piston system 3 / is provided on the movable section 2bA of the cylinder-cylinder system 2b, 2bA; the movable member 37A of the system 37 is designed to act on the stop 33A of the blade 33. A hydraulic control member 37B of the system 37 causes the movable section 37A to be lowered after the limit switch 2 ^ A has stopped the section 2bA; this lowering is interrupted when the lower end of the link 37A reaches a light beam or a light beam from a detector 3bA-3aB with a photoelectric line a little above the stop joA regardless of the level previously reached by this, the link 3 / A is in this way locked and determined just above the stop 33A. additional lowering of the shovel 33 as soon as the unit 2bA - 3 / is lowered during the stripping cycle. When the section 2bA is raised, the link 3 / A is also raised with respect to the cylinder of the system 37.

After the second pressing stage (pos. 5), the frame is prepared for stripping in the following station b by raising it as high as necessary so as not to j with the size of the links which are attached in the following station 7 the stripping station is to get in the way, in this station 7 the frame 21 arrives in a raised position and finds the shovel 33 ready to pick up the stripped tiles. The paddle 33 will remain in the stripping position for the number of stripping operations that are to be superimposed. With each stripping on the blade, the latter is lowered by the additional thickness equal to that of the stripped tile. Fig. K shows the level which is reached by the shovel 33 at the beginning, while the following Fig. 5 shows the arrangement

. 609882/0368

shows after four subsequent strippings. Before everyone Stripping determines the link y / A an additional lowering the shovel and the already stripped tiles. After stripping and overlays as intended are finished, the scoop 33 is moved away (see Fig. 0), so that the plate 3b with the superposed Tiles can be unloaded.

This system allows a remarkable saving of time. Indeed, the shovel no longer reciprocates for each pressing process (as happens with conventional machines), but a back and forth movement every three, four or more pressing operations. Because of the overexposure, you get a considerable one Saving of plates (equal to the number of pressing operations during the full path of a plate divided by the Number of stacking uneu), a higher one. Speed from one pressing operation to the next due to the smaller ones Number of movements to be performed and also a reduction in size the size of the drying or deposition cells.

Two press operations are provided in the machines (as can be seen in Figure 2); in fact, although a faster cycle is obtained, it is not necessary to decrease the pressing time, which is related to the natural rate of absorption of moisture from the first semi-dense layer to the almost dry second layer, which does so achieves that it is pressed twice in two successive situations .

The manufacturing process should be adapted to the requirements, in particular in order to increase the number of stacking. In particular , one should act in that the aggregate materials and the grain size are selected in order to increase the consistency of the tiles after pressing;

You can also provide - especially in the case of presses with Do it. with multiple shapes - to move the panels directly, without storing the plates in trolleys.

FIG. 1 shows a second embodiment of the inventive concept which can be used in already existing conventional presses without, however, creating constructive complications in the molding press. According to this embodiment, the tiles are stripped one by one, picked up and placed on the pile of tiles formed with tiles piled on top of the panels passing in front of the blade. In this case, the filings are stripped onto the paddle of the conventional press and are removed from it and placed on the plate, which stands in front of the paddle as long as is necessary for the stacking.

is raised. 4y denotes a vague _f which carries the blade 50, which is designed to receive the stripped tile M10. The carriage ^ y can slide on tracks and is operated by a hydraulics system 52. When the toagen 4y is moved along the ducts 51 under your new frame ip, the shovel is a little under the frame and can pick up the tile pressed out by the stamp 4 /. After a tile has been stripped off, the carriage 4y with the shovel 50, which carries the tile M10 that has just been stripped, is moved outward to the position shown in FIG is on a motion slide 5 7; one or more stacks of new tiles M12 are thus formed on the plate. The picking up and transfer of the tiles are carried out with a suction plate 59 operated by a cylinder-piston system bü to be raised and lowered with respect to the carriage Oi. This car oil can discharge; Guides bj slide from the position for picking up (shown in solid lines in the figure; to the position for placing on the floor 55 to form the stack; these two positions are defined by stops by and b7, and the carriage 61 is in of the embodiment controlled by a chain by which is operated by a reduction reversing gear 71.

In connection with the presence of a different number of thicknesses of the tiles M12 in the pile ^{formed on the plate:} j5 , the lowering of the suction device 5y must be different in order to deposit the tile or brick at the correct height. To achieve this, a detector 73 with a photoelectric line is provided on the movable suction unit, which detector is designed so that it interacts with a reflective surface 75; the beam of the cell 73 is immediately below the tile MX which passes through the

This suction device is designed in such a way that it provides close support elements such as protection and support holine for the tile held by the suction effect; the suction device is connected to a vacuum source with a control valve for picking up and releasing the tile.

With this solution the stripping system remains conventional and the external device, tij , bl, ^ y is added.
