METHOD AND APPARATUS FOR SEPARATING STEAM- CURED AERATED CONCRETE UNITS This invention refers to a method and apparatus for unloading steam-cured aerated concrete units, already cut before the steam curing, wherein a mold content still not separated through cut is brought between two pairs of rollers arranged one after the other and having different periphery speeds.
Aerated concrete is normally produced in the following way: Finely crushed raw materials, containing lime and silicic acid are mixed with water and then some porosity-forming agent, such as aluminum powder, is added, whereafter the mass obtained is cast into relatively large molds where it is left to expand and to bind to a consistency suitable for dividing it into smaller units. While in this plastic state the mold content is divided into the desired units by sawing with cutting devices, such as wires, braced in frames. After dividing, the material is brought into horizontal autoclaves to be steam-cured. When the cured material arrives from the autoclaves to be unloaded and stored in groups of different units, there may, when using certain raw materials, appear some adhesion in the saw cuts rendering the separating difficult.
All manual methods used for the separating have in common that they require a good deal of labor and that the risk of damage is relatively great, particularly at the corners of the units. Some mechanical devices for facilitating the separating work are known earlier, e.g. by the Swedish Pat. 164,138. They are preferably intended for large reinforced aerated concrete units but have proved less usable for masonry blocks for instance, because their use is too time consuming and rather costly.
The present invention relates to a solution of the problem of separating steam cured aerated concrete units, preferably blocks, mechanically. According to the invention the mold content arriving from the autoclaves is, before being separated, brought between two pairs of rollers arranged one pair after the other in the transport direction and separately driven, the rollers of the first or downstream pair having a somewhat higher peripheral speed than those of the second or upstream pair. By the difference of speed between the pairs of rollers a pulling force arises, working between the aerated concrete units to make them separate at the saw cuts. According to one embodiment of the invention, one of the rollers in the first pair has a greater peripheral speed than the other one in the same pair, whereby, beside the pulling force, there arises a breaking moment contributing to the separating of the aerated concrete units from each other. The method and apparatus of the invention will be described in detail here below in connection with a' statement of one way of constructing a device for practicing it:
In the drawings:
FIG. 1 shows a schematic arrangement of a separating device including the features of the present invention.
FIG. 2 is an enlarged detailed view of a part of FIG. 1.
FIG. 1 shows the installations around an separating device. On an endless belt conveyor 11, the mold content still not separated (though divided by a cutter) is placed in such a position that the dividing cuts in the aerated concrete mass are perpendicular to the moving direction of the belt which transports it through the separating device 12. For continuous transporting away of the separated aerated concrete units, there is behind the separating device a further endless belt conveyor 13. This one may consist of a rubber strip, to protect the units against edge damage. Alternatively the units may be palleted immediately after separating and the pallets transported away.
The apparatus functions as follows. Referring in particular to FIG. 2, divided and autoclaved mold content is transported on the belt conveyor 11 and seized by the rollers 14 and 15 which possess the same peripheral speed as the conveyor 11. The roller 14 is arranged so as to press against the mold content with a certain force perpendicularly. to the transport direction. The block A passes the second rollers I4 and 15 and when these have seized the block B, the block first mentioned has already been brought in between the first rollers 16 and 17, the roller 16 pressing against block A with a certain force perpendicularly to the transport direction. Because the rollers 16 and 17 of the first roller pair possess a peripheral speed somewhat greater than that of the second pair of rollers, and particularly if the 16 has a still greater peripheral speed than the 17, there arises a pulling force and a bending moment in the mass separating the blocks at the saw cuts. The block A falls down onto the belt conveyor 13 and is brought away. The moment of the roller 16 during this operation approaching 0, this roller is lifted by an automatic control device, not described here, and, after a certain time interval for preventing damage on the edges-of the aerated concrete, it starts pressing against the next block. The length of the time interval mentioned depends on the distance center to center between the rollers which distance in its turn is decided by the smallest size of the blocks treated. The rollers 14 and 16 may suitably be fixed to one end of levers l8, 19, preferably driven mechanically, e.g. by hydraulic cylinders.
The device thus operates so as to separate the aerated divided concrete automatically and continuously at the saw cuts without any need adjust the dimensions.
