    Device and method for manufacturing special formats of masonry bricks or masonry bricks, resp. masonry dressings
    The invention relates to a device, resp. a method for manufacturing special formats of masonry bricks or masonry bricks. The invention further relates to a conveyor belt for supplying masonry bricks or masonry bricks to a sawing device. Finally, the invention relates to a method for manufacturing masonry dressings.
    Sand-lime bricks are manufactured by pressing lime and sand in a pressing device and a subsequent hardening under steam pressure. DE 10 2005 031 236 B4 discloses such a pressing device which comprises a mold with several mold spaces that have different cross sections. Depending on the dimensions of the brick bricks to be produced, one of these molding spaces is filled with a correspondingly dimensioned amount of soil material and pressed by means of pressed stamps. After pressing the green bricks, they are cured in a curing installation.
    It is also known to further process masonry bricks or bricks for masonry bricks produced in this way into special formats. To this end, DE 0 2005 048 81 A1 describes the value of masonry bricks or bricks described in DE 0 2005 048 81 A1 to make saw cuts, e.g. oblique cuts or miter cuts. Masonry bricks and sawn designs of a special format are made into masonry joints in accordance with the specified order in accordance with the specified order.
    Circular saw devices are used in particular as sawing devices. DE 691 11 044 T2 discloses a miter cutting machine in which the objects to be cut can be moved back and forth on a table. The cutting device is held on a rigid holder which, however, is pivotable in such a way that the cutting edge always engages the same location in a recess in the table. The transport of objects to be cut on a conveyor belt to guide them to a sawing device is also known. To this end, DE 42 06 274 A1 describes a monoblock installation for cutting stone slabs, wherein the objects to be cut lie on a conveyor belt. The belt serves for loading and unloading the machine and is cut by a circular saw which is movably mounted in several directions and which itself is moved towards the object to be cut.
    The invention has for its object to provide a device and a method for manufacturing special sizes of masonry bricks or masonry bricks, whereby any predetermined miter cut or oblique cut can be made in masonry bricks or bricks of any size by means of a sawing device sinking into the bearing surface or a saw blade thereof. A further purpose is to provide a conveyor belt for supplying masonry bricks or masonry bricks to a sawing device, which allows passage of a sawing device or saw blade thereof only through the upper belt portion of the conveyor belt. Finally, a particularly rational method will be provided for the manufacture of brickwork dressings with assembled elements of brickwork bricks and designs in a special format.
    The object with regard to the device for the manufacture of special masonry formats or masonry bricks is achieved with the features of claim 1.
    For the production of special sizes of masonry bricks or masonry bricks, in particular sand-lime bricks or bricks thereof, a device is provided which comprises a sawing device for sawing the masonry bricks or bricks and a feeding device for supplying the objects to be processed to the sawing device. The feed device has an upper element on which the brick or green brick to be processed can be placed. This can be a movable platform, a mobile table or a sled. However, this upper element of the feed device is preferably a conveyor belt, for example a belt conveyor, a chain conveyor or the like. The supply device furthermore has a lower element below the upper element, which has a distance therefrom, so that the upper and the lower element define a gap. The saw device or a saw blade thereof is pivotable relative to the feed device about an axis of rotation, so that oblique cuts or miter cuts, for example, can be made on the object to be processed. The pivoting can take place here by means of a manual adjustment or by an automatic pivoting device on the sawing device or a holder device for the sawing device. On the upper element, i.e. for example on the above-mentioned sleigh, the table, or on the platform or the conveyor belt, a saw gap is provided through which the sawing device or saw blade can be guided at least partially. In the case of the conveyor belt, this sawing gap can be designed in that the conveyor belt itself is divided in length, so that two conveyor belts are arranged running parallel to one another at a distance from each other and which are advantageously driven at the same speed.
    According to the invention, the axis of rotation of the sawing device or saw blade is at least approximately in the area of the upper element of the feed device, preferably at the height of the supporting surface for the masonry brick or masonry brick formation. In this way the sawing device or saw blade is not moved sideways or only slightly to the side when pivoting within the sawing gap at the height of the bearing surface, so that the sawing gap can be dimensionally small accordingly. Due to this small gap, an object of almost any size can be processed. Therefore, smaller stones or bricks can also be sawn and the corresponding object certainly lies on this during the sawing process.
    The object preferably lies flat on the support surface. The support surface is preferably arranged close to the saw blade.
    The intermediate space bounded by the upper and the lower element is designed in such a way that the area of the saw device or of the saw blade which is guided through the saw gap can be received in any desired angular position. Swiveling with a sunken saw device or saw blade is possible without hindrance. It is advantageous to allow the sawing device to sink sufficiently deep into the sawing gap to ensure that the masonry or the brick is completely cut.
    According to a special embodiment of the invention, there is provided a circular saw device with a circular saw blade. In order to achieve a clean cut without breaking out material parts, it is advantageous to have the saw blade sink into approximately half of it in the saw gap. Consequently, the lower element of the feed device must also have a distance of at least about half the diameter of the saw blade from the upper element.
    A very special embodiment of the invention provides that not only the upper element of the feed device is a conveyor belt. Rather, an endless conveyor belt may be provided, so that the upper element has a forward-running belt portion that forms the support surface for the masonry bricks or the green bricks and the lower element has a reverse-running belt portion.
    In order to be able to provide the necessary space between the upper and the lower belt section with such a construction for receiving the desired area of the sawing device or the saw blade, two correspondingly dimensioned rollers can be used for tensioning the endless conveyor belt.
    However, this conveyor belt is advantageously guided around at least three rollers which form the corners of a triangle or a polygon in the side view of the conveyor belt.
    The conveyor belt can thus be tensioned by two rollers arranged at the top to form the conveying surface and the lower strap part can be kept at a distance by at least one roll arranged at the bottom. In the case of the use of a circular saw device it is particularly advantageous to bring the axis of rotation of one of the rollers arranged below into an at least approximately vertical arrangement with respect to the axis of rotation of the saw blade. This leads to a particularly space-saving construction of the endless conveyor belt.
    The feeding device may further comprise a depositing and removing device, in particular a robotic device, which places the objects to be processed on the upper element of the feeding device, i.e. for example on the upper belt part of the conveyor belt, and removes it again after processing.
    With regard to the conveyor belt for supplying masonry bricks or masonry bricks, this object is achieved with the features of claim 5.
    A conveyor belt is used for supplying masonry bricks or masonry bricks to a sawing device, e.g. for making oblique cuts or miter cuts. According to the invention, this conveyor belt is longitudinally divided for at least partial passage of the saw device or a saw blade thereof, wherein the conveyor belt comprises an upper belt portion and a lower belt portion running in opposite direction to the upper belt portion and which define a gap in which the sawing device or saw blade thereof is at least partially galvanized. The upper belt portion of the conveyor belt is tensioned by two top-mounted rollers and the bottom belt portion is spaced by at least one bottom-mounted roller, so that the bottom belt portion has a distance to the sawing device or saw blade thereof.
    The sawing device preferably comprises a circular saw blade. In this case it is advantageous for a space-saving structure if a roller arranged at the bottom lies in an at least approximately vertical arrangement with respect to the axis of rotation of the saw blade. Such a feed device constructed in this way can then cooperate with a saw blade which is galvanized in the distance region of the divided conveyor belt which forms a saw gap, which saw blade slopes obliquely with respect to the bearing surface of the conveyor belt, respectively. is tilted.
    The object with regard to the method for manufacturing special formats of masonry bricks or masonry bricks is achieved with the features of claim 7.
    For the production of special formats masonry bricks or masonry bricks, unprocessed objects, in particular bricks coming from a pressing device or bricks supplied from a hardening installation, are supplied to a sawing device by means of a conveyor belt. According to the invention, the sawing device or saw blade thereof for the processing process is set at a predetermined angle with respect to the bearing surface of the conveyor belt prior to the supply of the object to be processed. Subsequently, the sawing process takes place by means of correspondingly sliding the conveyor belt forward. After the corresponding processing, a transport device, e.g. a robot device, removes the processed brick bricks or brick brick formations from the conveyor belt for further transport to, in particular, a hardening truck or a transport truck for further routing to a storage location or directly to a shipping device. The removal of the processed brick blocks or brick brick formations from the conveyor belt can preferably take place either in the direction of movement of the conveyor belt behind the saw device or the saw blade, or after a return movement of the conveyor belt, before the saw device or the saw blade.
    If a further sawing process is to be carried out, for example for the manufacture of a facing brick, then the partially worked brick or brick can be guided once again to the sawing device, wherein for the further processing step an altered angle of the sawing device or the saw blade with respect to the support surface of the conveyor belt can be adjusted.
    For this further processing step, it is possible that the transport device, i.e. e.g. the robot, displaces the partially processed object. Another embodiment provides that the conveyor belt is moved backwards for the further sawing process.
    The processing process can also provide for the transport device to also deposit the raw masonry blocks or bricks on the or a hardening trolley.
    Finally, with the features of claim 10, the object is achieved with regard to the method for manufacturing masonry dressings.
    The invention herein provides that such masonry dressings are produced as follows. First, masonry formations are formed in a pressing device and partially cured in a hardening installation and guided to a storage location, a stacking and / or a packaging device. Another part of the green bricks produced is subjected to the above-mentioned process and then guided to the storage location, the stacking and / or the packaging device, where the masonry bond is assembled there by means of a predetermined assembly.
    The invention is explained in more detail below with reference to drawings of an exemplary embodiment. In the drawings: Fig. 1 shows in perspective view an installation for the production of green bricks and special formats thereof, comprising a green saw and a conveyor belt; figure 2 shows a side view of the arrangement of the green saw and the conveyor belt according to figure 1 with a saw blade that is countersunk in the cutting position; figure 3 shows the arrangement of figure 2, but in a front view and with a slanted saw blade for performing a miter cut.
    Figure 1 shows an installation 1 for the production of sand-lime bricks and special formats thereof. This installation comprises a press 3 for forming and pressing the green bricks. To this end, a molding space of this press 3, not shown in detail, is filled with soil material in the known manner and is compressed by means of two pressing stamps moved towards each other to form a sand-lime bricks.
    The broth ejected from the molding space can then be removed by a robot 5 from the pressing table 7 and placed on a hardening trolley 9 which feeds a stack of these bricks to a hardening installation for hardening under steam pressure.
    However, the greening can also be intended for further processing. Namely, on a building site, not only block-shaped sand-lime blocks or surface elements that are formed in the press and hardened in the hardening installation are required, but special formats must also be provided, in particular supplementary bricks such as facing bricks, window and door sections and the like. These can either be cut to size from the surface elements or from blocks of sand-lime brick on the building site. For a reduction of waste on the building site, it is, however, advantageous to supply pre-processed special formats in accordance with the building plan from the company where they are produced.
    To keep the amount of waste as small as possible in the company where they are produced, the special sizes are not made from hardened sand-lime bricks. On the contrary, the green bricks are already cut into the required shape by means of a green saw 11, so that the cut ground material can again be supplied to a hopper of the press 3.
    The joining saw 11 is built on a table 13 of a support frame 15. On this table 13 a rotatable support frame 19 is arranged which can be pivoted about a horizontal axis by means of a hinge 17. The rotation of the support frame 19 is carried out by a hydraulic device 21.
    A support arm 25 is coupled to the support frame 19 via a further hinge 23 which carries a circular saw blade 27 which is driven via a drive motor (not shown). The hinge 23 is suitable for performing a height adjustment of the circular saw blade 27. A corresponding hydraulic device 29 is also provided for this.
    The sand-lime bricks intended for further processing is placed by the robot 5 on an endless conveyor belt 31. This conveyor belt 31 serves to feed the bricks to the circular saw 27 and thus also supplies it for the sawing process. The conveyor belt 31 is tensioned by a drive roller 35 which is driven by a drive motor 33 and a roller 37 arranged horizontally relative thereto, as well as by a tensioner roller 39 lying deeper compared to these rollers 35, 37, so that in the lateral image there is a a triangle image is created, as this is particularly clear in figure 2.
    Tensioning the conveyor belt 31 in this way is necessary in order to create a sufficient distance from the reverse running, lower-lying belt portion of the countersunk saw blade 27. The saw blade 27 namely sinks in the countersunk operating state in the position tensioned by the rollers 35, 37, 39 gap 41. For this purpose, the conveyor belt has a divided embodiment, so that a saw gap 43 is created.
    Figure 3 shows the arrangement of the sawing device in the case of an oblique cut. The hydraulic device 21 has moved the support frame 19 in an oblique position for this purpose. This has the consequence that the saw blade 27 is also tilted accordingly. The sawing edge located at the bottom is displaced in this way within the gap 41 in the form of an arc and is therefore also in a displaced position relative to the sawing gap 43.
    As can be seen in particular in Figure 1 (Figure 2), the hinge 17 for rotating the support frame 19 and therefore for tilting the saw blade 27 is at the same height as the conveyor belt 31. In this way ensuring that the axis of rotation of the saw blade 27 passes through the saw gap 43. Thus, when the saw blade 27 is turned, there is no lateral displacement of the saw blade 27 within the saw gap 43. The saw gap 43 can thus be kept particularly small.
    After a sawing process has taken place, the robot 5 removes the tailor-made bricks from the conveyor belt 31 in the direction of movement behind the saw blade 27 so that it can be deposited on the hardening trolley 9 for subsequent transport to the hardening installation. rotational direction to be moved backward to reposition the processed green brigade before the saw blade 27 to remove it before the saw blade.
    However, a second process can also be connected to the first sawing process. To this end, the conveyor belt 31 displaces the once-worked brigade in front of the saw blade 27. in a reverse direction of rotation. The changed cutting angle is adjusted by means of the hydraulic device 21 and the following sawing process is carried out. Alternatively, however, the robot 5 can also move the green brigade to prepare it for the further sawing process.
