Definitions

  • the invention relates to a device and a method for filling mineral mixture, in particular fresh concrete, in mold cavities of a molding frame of a compacting device.
  • the compacting device is also called a brick forming machine.
  • the devices for compacting have mold frames, are used in the mold elements. These mold elements, which are also called mold cavities, are placed on a workpiece carrier, which is also called production pallet or pallet or board.
  • the mold frame which is open at the top with a mineral mixture, e.g. with fresh concrete, ie a mixture with one or more different binders, e.g. Cement, and sand, gravel and / or other additives, which is liquefied by a liquid filled.
  • a mineral mixture e.g. with fresh concrete
  • binders e.g. Cement, and sand, gravel and / or other additives
  • the fresh concrete is usually used in a mixing process, e.g. mixed with a concrete mixer and thereby homogenized.
  • a conveyor belt or a comparable transport device By means of a conveyor belt or a comparable transport device, the fresh concrete is led to a so-called bunker, in which the fresh concrete is briefly stored for further use between.
  • the bunker corresponds to a hopper, with an openable closure on its underside.
  • the fresh concrete falls - at least when the hopper is still substantially empty - from a high height to the bottom of the hopper. From the hopper, the fresh concrete is then filled into a so-called Greschlitten, wherein the fresh concrete - due to the funnel shape - settles conically in Greschlitten.
  • the filling carriage is then accelerated with a high acceleration and moved over the mold frame, there to deliver the fresh concrete to the mold frame. Due to the high acceleration, a more uniform distribution of the conically arranged fresh concrete is achieved in the mold cavity of the mold frame.
  • the mineral mixture in particular the fresh concrete, then compacted with a stamp, which enters from the top of the mold cavity and presses under the vibration of the workpiece carrier or the stamp air bubbles from the fresh concrete addition.
  • the object of the present invention is therefore to fill a mineral mixture, in particular fresh concrete, in such a way in a molding element before a compression process, so that the mineral mixture is largely homogeneous and / or evenly distributed in the mold element.
  • the present invention solves this problem by a device for filling mineral mixture, in particular fresh concrete, in a molding frame of a compacting device according to claim 1 and a method according to claim 14.
  • the device according to the invention comprises a container, which is also called Basitten.
  • the container has a filling opening and an outlet opening. Through the filling opening mineral mixture can be poured into the container, so that the container can absorb the mineral mixture.
  • a funnel which is also called bunker, is filled with the mineral mixture in the filling opening.
  • the mineral mixture is discharged, this through the outlet opening, e.g. is spent in the mold frame.
  • the device according to the invention comprises at least one metering shaft, which is arranged between the filling opening and the outlet opening in the container.
  • mixing and / or metering tools are arranged at the metering shaft.
  • the metering shaft is set up such that its rotational speed can be varied and that the amount of mineral mixture taken up, which is discharged at the outlet opening, is dependent on the rotational speed of the metering shaft.
  • the device comprises a linear movement means, which serves to transfer the container between at least a first and a second position.
  • the device is thus adapted to receive fresh concrete in at least the first position by means of the filling opening and during the transfer from the first to the second position, the transfer from the second to the first position and / or in the second position fresh concrete by means of the outlet opening issue.
  • the linear movement means preferably serve to carry out a substantially horizontal movement of the container.
  • the exit opening is opened at a small distance, e.g. less than one meter, e.g. less than 20 cm, 10 cm, or more preferably less than one centimeter, moved to the mold frame along the mold frame so that the mineral mixture can fall into the mold frame over only a small distance from the exit opening.
  • the device according to the invention thus serves to deliver the mineral mixture by means of the metering shaft during the movement of the container (by means of the linear movement means) via the outlet opening in the mold frame and to homogenize in this case.
  • the mineral mixture is distributed with substantially uniform masses in the mold cavity.
  • the mass differences of the mineral mixture in the individual mold cavities thus remain below a predefined - relatively low in the prior art - low limit.
  • Mineral mixture in particular fresh concrete, that is, through a container of high altitude, e.g. from a concrete mixer was filled through a hopper into the filling opening and thus present inhomogeneous in the container is thus rehomogenized with the homogenizer and then filled with the metering during a linear movement with the linear motion in the mold frame immediately above the mold frame from low altitude. Furthermore, no high acceleration of the container or the filling sled is necessary because the mineral mixture - dosed with the dosing - distributed over the entire mold frame can be filled into the mold cavities.
  • the filled mineral mixture in the mold frame or in the mold cavities is thus substantially uniformly distributed over the entire volume of the mold frame or mold cavities and homogeneous. This ensures even compaction in the production of concrete products made from the mineral mixture, so that concrete products of essentially constant, consistent quality are produced.
  • the device comprises a homogenizer, which can also be called mixing device.
  • the homogenizer is arranged in one direction - seen from the filling opening to the outlet opening - in front of the dosing.
  • the homogenizer serves to mix the mineral mixture, e.g. was introduced through a funnel from a high altitude in the filling hole and thus has become inhomogeneous, in addition to the dosing to homogenize even better.
  • mineral mixture can be introduced through the filling opening into the container, which moves past the homogenizing device or by means of the homogenizing device and is thereby homogenized.
  • the homogenized mineral mixture is then fed to the metering shaft and discharged by means of the metering at the outlet opening.
  • the homogenizing device comprises a homogenizing shaft with mixing tools.
  • Mixing tools are, in particular, fingers arranged on the homogenizing shaft, at the outer ends of each of which a mixing hand, eg consisting of a metal plate, is formed with plastic cover. Furthermore, mixing tools are possible that resemble a screw.
  • the homogenizer shaft with the mixing tools thus serves to homogenize the mineral mixture and to further movement of the mineral mixture in the direction of the outlet opening.
  • the rotational speed of the homogenizing shaft is dependent on the rotational speed of the metering shaft.
  • the homogenization is carried out at a higher speed. If, on the other hand, less mineral mixture is released via the outlet opening, a slower homogenization can also take place at a slower rotational speed, that is to say at a lower rotational speed, of the homogenizing shaft.
  • the performance of the metering shaft and the homogenizer ie in particular their torque, speed and speed to the product to be manufactured and / or the mineral mixture used are adaptable.
  • the metering shaft is arranged in the region of the outlet opening.
  • the arrangement is chosen in particular such that in at least one predefined position of the metering a connection between the filling opening and the outlet opening is at least partially, largely or substantially completely interrupted.
  • the metering shaft which is arranged in the region of the outlet opening, wherein then - at least in one position of the metering shaft - no mineral mixture can escape from the outlet opening.
  • the outlet opening is even blocked by the stopped Dosierwelle in a certain position relative to the container and / or the filling opening. Leakage or leakage of the mineral mixture can therefore be stopped controlled.
  • the speed of the transfer of the container from the first to the second position and / or the transfer from the second to the first position at least in a predetermined range depending on the rotational speed of the metering shaft. That is, at least in one area of the movement of the Container by the linear movement means, this movement is dependent on the rotational speed of the metering shaft. Dosing the fresh concrete when filling in a mold frame is thereby guaranteed in the way that the distribution of fresh concrete on the mold frame can be made very evenly.
  • the rotational speed or speed of the metering shaft is dependent on the speed, direction of movement and / or the position of the linear movement means.
  • the metering shaft is cylindrical, with metering tools being arranged on the cylinder jacket surface of the cylindrical metering shaft.
  • metering tools are e.g. Flat iron or sheet metal, which according to further embodiments on the cylinder jacket surface, e.g. are applied by welding.
  • manufacture of the metering shaft in one piece with the metering tools e.g. by casting or milling possible.
  • the device has one or more scrapers in the region of the outlet opening, wherein the scraper serves to strip off the mineral mixture or fresh concrete entrained by the metering shaft.
  • the scraper is e.g. made with metal, rubber or plastic.
  • the scraper is adjustable. The distance between scraper and metering shaft is thus variable.
  • the scraper serves according to a further embodiment, e.g. in cooperation with the dosing of the dosing, in a certain position of the dosing to complete the outlet largely or substantially completely opposite the container or at least in a region of the outlet, so that no or only negligible little mineral mixture can escape through the outlet opening.
  • the scraper is used in particular during the movement of the metering for stripping the mitbeezeden with the metering mineral mixture, so that the amount of mineral mixture that is conveyed to the outlet opening is even better dosed.
  • the metering shaft and / or the homogenizing device is designed in such a way that in its axial edge region, ie in the edge region of the cylinder jacket surface which lies in the area of the cylinder cover surfaces, more mineral mixture is to be conveyed than in the region lying in between in the axial direction.
  • This embodiment of the metering shaft is achieved according to a further exemplary embodiment in that the metering tools arranged on the cylinder jacket surface are distributed or formed such that more mineral mixture is conveyed in the edge region than in the central region.
  • the mineral mixture is braked by the frame of the container, so that less mineral mixture would be promoted with the metering wave in these areas without this special embodiment.
  • a uniform distribution of the fresh concrete in the mold frame is therefore possible by this embodiment.
  • the conical mineral mixture received by the filling carriage is thus better conveyed to the edge regions of the metering shaft.
  • the container has a conveyor belt which is adapted to convey the fresh concrete at least in a region of the container in a direction from the filling opening to the outlet opening.
  • the conveyor belt is arranged in particular in the bottom region of the container and serves to support the homogenizing device, so that the mineral mixture is reliably conveyed from the filling opening in the direction of the outlet opening.
  • the conveyor belt corresponds to the metering shaft, so that the conveyor belt, in particular in combination with a homogenizer, serves as metering shaft.
  • the conveying speed of the conveyor belt is dependent on the rotational speed of the metering, whereby is ensured by this dependence that in the dosing shaft always enough mineral mixture is available, so that moved along by the formation of dosing Amount of mineral mixture can be determined solely by the rotational speed of the metering. A dosage of the fresh concrete discharged from the outlet opening is therefore certainly possible.
  • the container comprises a base plate, wherein the base plate in each case has a rounded cross-section in the regions below the metering shaft and below the homogenizing device designed as homogenizing shafts.
  • the soil bleaching therefore has grooves which run parallel to the axis of the waves.
  • the bottom plate is adapted to the outer radii of the metering with dosing and / or the homogenizer with the mixing tools, so that by the rotation of the waves substantially all the mineral mixture that is held in the container, can be moved by means of the waves.
  • the waves thus reach as many areas of the container volume, so that a setting of fresh concrete is prevented.
  • the metering shaft and / or the homogenizing shaft are arranged in the container in such a way that the mixing tools and / or the metering tools each strip and / or touch the bottom of the container during the rotary movement of the metering shaft and / or the homogenizing shaft in predetermined regions.
  • the dosing shaft and / or the homogenizing shaft and its tools are provided with a coating, in particular an anti-adhesion coating, in order to prevent mineral mixture from adhering to the shafts and / or the tools.
  • the invention also includes a method for filling mineral mixture in a mold frame with a device according to one of the aforementioned embodiments.
  • Fig. 1 shows an embodiment of the device 10, wherein the device 10 comprises a container 12 which is movable with a linear movement means 14 between a first and a second position in the direction of arrow 15 and 16.
  • the linear movement means 14 are designed here as hydraulic cylinders.
  • the container 12 is mounted on a machine table 17, wherein on the surface of the machine table 17, not shown mounted rollers are provided to move the container 12 with the linear movement means 14, while the weight of the container 12 is substantially absorbed by the machine table 17 becomes.
  • a filling opening 18 of the container 12 is located below a funnel 20.
  • the funnel 20 is filled from its upper side with fresh concrete 22, for which purpose e.g. a - not shown - concrete mixer truck moves backwards to the hopper 20 and filled the fresh concrete 22 in the hopper 20 from above.
  • the hopper 20 thus serves to fill the container 12 via the filling opening 18 with fresh concrete 22.
  • the container 12 is shown here schematically in section, so that you can see inside three arranged waves whose axes of rotation perpendicular to the plane of the drawing.
  • a first mixing tool 24 is arranged, which here has a homogenizing shaft 25.

  • the Homogenisierwellen 25 of the homogenizer 24 are rotated so that the fresh concrete 22 can propagate in the entire container to the metering shaft 28.
  • the container 12 is transferred with the linear movement means 14 to a second position.
  • This second position is in Fig. 2 shown.
  • the metering shaft 28 also rotates in the clockwise direction in the example shown, so that the fresh concrete is filled into the shaping frame 34 during the transfer to the second position.
  • a dependent of the volume of the mold cavity of the mold frame 34 amount of fresh concrete 22 is filled into the mold cavities.
  • Fig. 2 Accordingly, the container 12 is now in the second position, wherein the fresh concrete 22, which was previously filled in the container 12, has now been filled from the outlet opening 32 in the mold frame 34.
  • the homogenizing shafts 25 of the homogenizing device 24 and the metering shaft 28 were each allowed to rotate at a speed dependent on the movement of the linear movement means. In this case, a quantity of fresh concrete 22 dependent on the rotational speed of the metering shaft 28 was then output via the outlet opening 32.
  • the container 12 is then returned to its first position, the concrete in the mold frame 34, which is now filled with concrete, compacted, and the compacted product from the mold frame - by lifting the mold frame - removed.
