Description

: BE2019 / 5283 1 | The present invention relates to a device and method for the manufacture of concrete articles. More specifically, the invention is intended for the manufacture of concrete articles by means of pressing an uncured concrete composition. ; These concrete articles can, for example, contain stones, | clinkers or tiles, but other articles are not excluded according to the invention.

It is known that it is financially attractive to manufacture concrete articles by pressing an uncured concrete composition, because in this case form-stable objects are formed very quickly, which can then harden elsewhere, outside the form used. To this end, a certain amount of uncured concrete composition is placed in a cavity of a mold provided for this purpose, which is then pressed by means of a punch of corresponding shape. The mold is also called a mold plate and is sealed at the bottom by a separate bottom plate so that when the punch presses the concrete composition and at the same time the mold plate is moved upwards, on the bottom plate the aidus molded beconner article | lagging behind ,. One nadeci of such known methods is that they | 5 do not allow to produce concrete articles where | different grades or types of concrete separated along | can be combined in one concrete article, where 9 there is a straight straight line of war between the 9 different scoring concrete at the top of the | 19 concrete article. | To combine different types of concrete in one concrete article, the cavity must be filled, simultaneously or otherwise, with the different types of concrete.

It goes without saying that without further measures a tight, straight dividing line can be obtained between the various types of concrete.

The present invention aims to provide a solution to at least one of the aforementioned and other drawbacks by providing a device and method which allows to manufacture a concrete article in which different kinds or types of concrete are combined and separated along each other,

The present invention has as an object a device for manufacturing concrete articles, which device comprises a reservoir for concrete with an exit through which the concrete can leave the reservoir, characterized in that the reservoir comprises at least two separate spaces for concrete, wherein the spaces

: communicating with the exit, a straight wall splitting the exit, which wall 8 partially protrudes; beyond or outside the exit 6. | An advantage is that because of the separated spaces two or: more scorten concrete separated from each other in the reservoir; can be provided. The different scoring concrete km can be distinguished from each other by, for example, their composition or color. It is also possible that the og surface structure of the cured concrete is different because different aggregates are used.

The split exit will allow the two types of concrete to fall simultaneously and separately from each other into a cavity of the mold, with the wall in the exit separating the two types of concrete.

220 In this way a tight separation can be obtained between both types of concrete.

According to the invention the wall partially protrudes beyond or outside the exit.

This has the advantage that the wall will ensure a good separation between the different types of concrete in the cavity of the mold, because the wall at this location will keep both types of concrete separate from each other. The final concrete article will therefore have a sharp and tight have a separation line between the two types of concrete,

Preferably, the device also comprises at least one mold with one or more noltes, the reservoir 9 being configured to pass through its exit over the cavities of the mold or the mold being configured | & is to be moved with its cavities under the outlet of the reservoir 9. A groove is preferably provided in the mold in which 9 the wall can slide.

This has the advantage that the wall with its edge can, as it were, slide through the cavity of the mold when the exit moves over the cavity.

This will provide guidance, so that the separation between the two types of concrete in the final concrete article can be established based on the location of the groove. Care should be taken to ensure that the straight wall extends in the direction of movement of the reservoir. it moves over the hoiten or the straight wall extends in the direction of travel of the mold as it is moved under the exit of the reservoir. in a practical embodiment, the reservoir is designed as an open tray with an open bottom serving as the aforementioned outlet, wherein in the open bin the aforementioned wall is arranged as a partition between the spaces and as a wall dividing the outlet, 39 Such embodiment has the advantage that the reservoir can be easily filled and that there is no need for pressure

| exit opening, allowing a complete filling of the | cavities of the mold is guaranteed when the cavities are over.

The invention also relates to a method for manufacturing concrete articles, characterized in that use is made of a device according to the | invention and that the method comprises the following steps: 9 - providing one or more mailboxes behind each other in the direction of movement of the reservoir | be placed, with optional support platform between each mold or not :; - filling the reservoir with concrete, whereby a different score or type of concrete is placed in each space; - moving the reservoir over the molds and the support platforms, ensuring that the exit moves over the cavities in the mold. The advantages of such a method, using a device according to the invention, are similar to those mentioned above. advantages of the device.

With the insight to better demonstrate the characteristics of the invention, as an example without any limiting character, some preferred variants of an apparatus according to the invention for manufacturing concrete articles and a method used therein have been described with reference to the accompanying drawings. , in which:

| figure il schematically and in perspective a device | according to the invention; figure 2 section according to line II-TII in figure 1; displays; | Figures 3 to & represent different steps of a method according to the invention.

The device 1 according to |. Is schematically shown in figure 1 the invention for the production of concrete articles 9 10 cm contains mainly a reservoir 2 for concrete 3 and, in this case case, also a mold 4 with one or more cavities 5.In the example shown, the mold 4 has two cavities 5, but this can also only be one cavity 5 or more than two cavities 5. molds d are provided. These mailers 4 can then, for example, be adjusted one after the other, as may, for example, be the case in a production line. According to the invention, the reservoir Z comprises openings 6 along which the concrete 3 can leave the reservoir 2, and it comprises at least two spaces 7a, 7b for concrete 5, which are separated from each other. The spaces 7a, Jo are connected with the outlet 6, whereby a straight wall 8 divides the outlet 6 into two parts 6a, 6b.

| In each of the aforementioned spaces 7a, 7b, a different type | of concrete 3, as schematically shown in the figures.

In the example of figure 1, and also visible in the cross-section of figure 2, the aforementioned wall 8 also serves as partition wall 8 between the aforementioned spaces 7a, 7b | of the reservoir 2, 9 10 In other words: the wall 8 extends: from the reservoir 9 to the outlet 6, so that the reservoir 2 9 comprises at least two spaces separated by a wall 8 Yes, 7b 9 for concrete 3, wherein the spaces 7a, 7b communicate 9 with the outlet 6, whereby the wall 8 extends up to | 15 the outlet &, so that the outlet 6 is split into two parts 6a, 6D. As can be seen in figures 1 and 2, the reservoir 2 is designed as a kind of open container 9 with an open bottom 10, which serves as the aforementioned output 6. It will be clear that this is only one possible embodiment. It will also be clear that in the same way three spaces 7a, 7b can be created, whereby the exit & is split into three parts Ga, 6b. As can be seen in figures 1 and 2, the device 1 also comprises one or more support platforms 11 which are arranged before and / or after the ml 4. In this case there is a

| provide support platform 11 in front and a support platform 11 after the mold 4 à, | The reservoir 2 can move over these support plates 11: &. Herein, the support platform 11 is provided with rails 12 and the reservoir 2 is provided with wheels 13 which can move on these rails 12. As a result, the reservoir 2 is configured to be displaced with its outlet 6 over the cavities 5 of the mold 4.

Figure 3 shows a cross-section as in figure Z, but in which the reservoir ZZ has been moved and is located partly above the mold 4. It is clear that this can also be realized in a different way than with the aid of the predefined rails 12. and wheels 13. By making use of the wheels 13, the reservoir 2 is designed as a so-called filling truck, which can, as it were, drive over the mai à.

But the mai 4 can also be configured to be moved with its cavities 5 below the outlet 6 of the reservoir 2, 1.6. the reservoir 2 is disposed immovably.

As can be clearly seen in Figures 1 to 3, the wall B protrudes partially beyond or beyond the exit 6. [It will be apparent later that this is advantageous for the | obtaining a perfectly tight dividing line between the 9 3 different types of concrete 3 in the final 9 created concrete article, 9 The wall & can for example with an edge 14 stex about half a Lot five centimeters from or beyond the exit.

It is not ruled out that the wall 8 protrudes less than half or more than five centimeters from or beyond the exit 6, this will mainly depend on the finish of the final concrete article to be produced,

In order to ensure that the reservoir 2 with protruding wall 8 can still slide smoothly over the mold and the support platform 11, a groove 15 has been provided in both the mold 4 and in the support platform 11, in which groove 15 can be inserted into the wall 8 with the aforementioned edge 14. It may be clear that the groove 15 is at least as deep as the protruding edge 14 of the wall B. As for the mold 4, it is in this embodiment composed of the mold plate 16 in which the Sn or more cavities L are arranged and a separate bottom plate 17 which forms the bottom of the cavities 5. This is visible in figure 3,

In this case, the device 1 is also, but not necessarily, provided with means 18 for lifting the mold plate 16 upwards and with means 19 for changing the bottom plates 17. This means both mechanical and robotic means 18, 19 can be used. a production line or the like, but can also be: for example handles 20 to be able to manually lift the mold plate 16 or handles 20 to lift the bottom plate 17. 19 can be removed, shifted or lifted. The operation of the device 1 for manufacturing ceton articles is very simple and as follows.

One starts from a starting position as shown in figures 1 and 2, in which the filled reservoir 2 is located on the supporting platform 11 next to the mold 4.

Subsequently, the reservoir will move towards the mold 4, so that it will thread over the mai 3. This is shown in figure 3.

Care is taken that the straight wall 8 extends in the direction of movement of the reservoir 2 while the reservoir 2 is moving.

During this movement, the wall 8 will slide into the groove 15 in the support platform 11 and then into the groove 15 of the mold 4. This will, as it were, be an automatic correct alignment of the reservoir 2 and in particular of the outlet 6 with the mai 4 cause,

When the reservoir 2 moves with its exit © over the cavity 5 3 or drives, as shown in figure 4, through | the cut-out 6 concrete 3 are poured into the cavity 5 of the 9. Since both parts 6a, 6b of the exit 6 extend at least 9 partially above the cavity 5, both | types or types of concrete 3 are poured into the cavity 5.

Through the wall 8, both types of concrete 3 will end up separately in the center 5. Since the wall 8 partially protrudes with its edge 14 from the outlet 6, it will protrude partially into the cavity 5. This results in a tight dividing line 21 in the concrete, as can be seen in figure 5. This dividing line 21 is created by the indentation that the wall & has caused in the concrete 3 when sliding over the cavity 5. The reservoir 2 will drive completely over the mold 4 and then continue to the next support platform 11 or return to the support platform 11 from which it came, depending on the arrangement of the production line.

This means that the reservoir 2 is no longer located over or above the mold d.

In a next step, the concrete 3 can be pressed. Use is made of so-called stamps 22 for this.

To this end, the device 21 is provided with one or more stamps 22 which can be moved up and down into the cavities 5 of the mold 4. In this case, an equal number of stamps 22 can be provided if there are cavities 5 in the mold 4. If there are several: molds 4, for example in a production line, the: stamps 22 can be moved from mold 4 to mold 4 or | the mailers can be successively shifted under 120 the stamps 22. The stamps 22 will be lowered towards the molds 4 to compress or press the concrete 3 in the holes 5,

This is shown in figures 5 and 6. In this case, but not necessary for the invention, the stamps 22 are provided on their underside 23 with a line-shaped protruding profile 24. With this profile 24, the stamp 22 will be positioned in the aforementioned dividing line 21 of pressing the concrete 3, In this way, the dividing line 21 is emphasized even more and made taut. After pressing by the stamps 22, the forming plate 16 and the stamp 22 are moved upwards, as shown in figures 7 and 8,

| The blank 17 of the mold 4 remains in place, together with the thus created compressed concrete articles 25, which in this case are tiles 25. 9 5 This bottom plate 17 can be removed and taken to a drying place where the tiles can be removed drying out, 9 A new bottom plate 17 or bottom plates 17 can be placed 9 10 and the mold plate 16 or mold plates 16 can be lowered again or other mold plates 16 9 can be lowered if one wishes to make other concrete articles 25 9 It is not excluded that the device 11 is provided with a second reservoir 2 for concrete 3, similar to the above-described first reservoir 2, but with the difference that it only comprises one space 7a, 7b for concrete 3, ie, is not provided with a wall 8.

The second reservoir 2 can be used to first pour a so-called core concrete 3 into the mold 4, whereby it will first drive over the mold 4, after which the second reservoir 2 will then drive over the mold 4 to transfer the two types of concrete 3. pour the core concrete 3, whereby again a tight dividing line 21 between the two types of concrete 3 will be obtained here, it is not excluded that the core concrete 3 is equal to one of the two types of concrete 3 in the first reservoir

2.

| It is possible here for both reservoirs 2 to follow one another, successively over the mold 4 or a series of | molds placed one behind the other drive 4, but it is also | possible that on either side of the mold 4 a reservoir 2 | 5 is placed, whereby first the second reservoir 2 travels back and forth over the mold 4 to pour the core concrete 3, after which the serste reservoir 2 then drives back and forth over the mold 4 9 for the two types of concrete. 3 Le deposit. Subsequently, the method can be continued as described above. The present invention is by no means limited to the nitvosrina discharge screens described by way of example and shown in the figure, because the invention according to the invention for the manufacture of concrete articles and a method can be used therein. according to different variants without departing from the scope of the invention.
