Definitions

  • the invention relates to a device for discharging a free-flowing casting material from a discharge container containing the casting material for dropping the free-flowing casting material into a mold.
  • the DE 30 41 905 A1 describes a concrete spreading device, consisting of a concrete container that can be moved relative to the formwork and is arranged above the formwork, with a slot-shaped star feeder on the bottom running transversely to the direction of movement, in which the star feeder is an annular channel that is open at the top and bottom and whose diameter is adapted to the blade diameter of the rotary feeder rotating therein and in which the metering of the concrete mass passing through the cellular wheel sluice in the unit of time, which exactly determines the concrete thickness in the formwork, can be controlled by the rotational movement of the cellular wheel related to the relative movement of the concrete container and formwork.
  • the GB 2 376 655 A describes a discharge device for lightweight concrete and comprises a plurality of tubes with dispensing openings, with a bottle vibrator being arranged in each tube for precompacting the lightweight concrete in the respective tube.
  • the bottle shaker can also be adjusted in height within the respective stepped tube to cover the free flow cross-section in the tube between a lowest position in which the bottle shaker occupies approximately three quarters of the narrower tube width and an uppermost position in which the bottle shaker only occupies half the wider tube width.
  • the object of the invention is to provide a device for discharging a free-flowing casting material from a casting material to create containing discharge container for falling entry of the flowable casting material in a mold that allows a variable and particularly uniform filling of molds.
  • the flowable casting material can be fresh concrete, for example.
  • the device for discharging a flowable casting material from a discharge container containing the casting material for dropping the flowable casting material into a mold can accordingly be used in particular in precast concrete plants.
  • the device can be used, for example, to produce double-wall elements or monolithic concrete components or reinforced concrete components.
  • the device serves to introduce the fresh concrete into the mold as precisely, uniformly and/or as splatter-free as possible.
  • the casting mold which in the case of fresh concrete is also referred to as a formwork device, among other things, can be used in manual production processes, in partially automated or fully automated production processes.
  • the formwork device is also referred to, among other things, as a pallet, which is particularly suitable for being able to be moved from one work station to the next work station in an automated production plant.
  • the formwork trough forms a mold into which the fresh concrete is poured in order to produce the desired concrete element, for example a wall element.
  • the formwork trough can be flexibly reconfigured so that differently designed concrete elements or wall elements can be produced.
  • the bottom of the formwork trough forms a preferably flat formwork table on which edge formwork elements can be attached or placed, which define the contour for the desired wall element and secure the fresh concrete poured into the formwork trough from flowing out of the formwork trough.
  • the edge formwork elements can be permanently installed edge formwork elements on at least one side edge of the formwork table.
  • the edge formwork elements can also be flexibly attachable edge formwork elements, which can be connected to the formwork table in a lockable and detachable manner.
  • Such flexibly attachable edge formwork elements can be magnet-integrated edge formwork elements, for example.
  • the edge formwork elements can also be fixed or flexibly attachable inner edge formwork elements. These inner edge formwork elements can define recesses in the wall element to be manufactured, such as windows or doors.
  • the discharge container which contains a predetermined quantity of free-flowing casting material, i.e. fresh concrete, is moved over the mold.
  • the fresh concrete flows out of the discharge container under the influence of gravity and falls into the mold due to the influence of gravity.
  • the discharge container can be mounted so that it can be moved automatically, for example by means of a running gear on a portal system which extends beyond the casting mold.
  • the flowable casting material should be discharged from the discharge container in as precise a dose as possible, so that the casting mold, which can vary in size depending on the individual case or have different built-in components and/or recesses, is filled with fresh concrete as precisely and evenly as possible, so that on the one hand no partial underfilling occurs and on the other hand no fresh concrete squirts out of the intended filling point.
  • fresh concrete generally has some self-leveling property, it is better for quality manufacture if the fresh concrete is poured into the mold as evenly as possible without the need for any significant self-leveling of the fresh concrete.
  • the discharge container which is designed to hold a quantity of casting material, is also referred to, among other things, as a concrete spreader or concrete distribution bucket.
  • the discharge nozzles are the sole outlets through which the free-flowing casting material, in particular the fresh concrete, is discharged from the discharge container, in which a quantity of casting material or fresh concrete is kept, into the casting mold.
  • At least two separate discharge nozzles are provided, each of which is connected to the common discharge container.
  • Each of these at least two separate discharge nozzles is assigned its own dosing device. Due to the separate discharge nozzles, which are fluidically connected directly to the interior of the discharge container, the pressure of the quantity of casting material that is stored in the interior of the discharge container can be applied evenly to each partial quantity of casting material that is in the discharge nozzle Act as a way to push the subset of casting material at the end of the respective discharge nozzle, without special conveyor drives, such as the star feeders DE 30 41 905 A1 or the bottle shakers after GB 2 376 655 A would be required.
  • the throughflow of the partial material flows is prevented by completely closing the flow cross section can be stopped completely, drip-free dosing of the partial material streams is also possible, which is not the case in the cited prior art, since there a residual amount can always drip or the discharge nozzles cannot even be completely closed at all.
  • At least two discharge nozzles are provided. However, more than two discharge nozzles can also be provided. Depending on the width of the discharge container or depending on the width of the discharge opening, there can also be three, four, five, six, eight, ten or twelve discharge nozzles. In a favorable embodiment, the discharge nozzles can also be provided in pairs. If the discharge nozzles are provided in pairs, then in the case of an assignment of a separate actuating unit to a dosing device of a discharge nozzle, the two actuating units of a respective pair of assigned discharge nozzles can be positioned on opposite sides. This forms a particularly space-saving design.
  • the discharge nozzles are each designed to discharge a partial quantity of casting material to be discharged from the discharge container in a separate material flow from the discharge container, the partial material flows can be metered particularly precisely and, for example, even if there are several discharge nozzles, a partial quantity of discharge nozzles can be completely closed, while one other subset of discharge remains open, so that, for example, the discharge width of the device changed, for example, can be shortened.
  • Such a shortening of the discharge width can take place, for example, during a continuous discharge process, for example if a concrete wall is to be produced that is narrower than the possible total discharge width of the device.
  • a reduction in the discharge width or a division into separate, smaller discharge widths can take place intermittently during a discharge process, for example if a concrete wall with window cutouts or door cutouts is to be manufactured, so that when the device sweeps over the mold, the discharge nozzles, which are currently located above the window cutouts or door cutouts, are switched off completely.
  • the dosing device preferably works without a conveyor drive for the partial material flows into the separate discharge nozzles. Dosing preferably takes place exclusively by controlling or regulating the flow rates of the partial material flows into the separate discharge nozzles individually by changing the flow cross section.
  • the dosing devices according to the invention are designed to individually set the flow rates of the partial material flows. At the same time, the dosing devices according to the invention are also designed to completely stop the respective flow of the partial material streams at the end of the respective discharge nozzle in the direction of flow of the casting material by completely closing the flow cross sections, at times and/or in periods of time in which no discharge of casting material from the discharge nozzle should take place. Such stopping of the discharge of casting material can take place individually for each discharge nozzle and thus independently of the control or regulation of the flow rates in other discharge nozzles.
