Definitions

  • the invention relates to a device for combining individual free-flowing material components of small weight to form a mixture with an exact formulation of the components, consisting of a number of storage containers corresponding to the number of components, a scale with weighing container assigned to each storage container and a weighing unit taking over the weighed components from the weighing containers and at least one mixer feeding conveyor.
  • a concrete preparation plant is known (DE-A-2 849 624), in which a mobile scale is provided, which can be moved below three silos, each with a material component, in order to pick up and weigh the components one after the other in the addition process and after completion of the Recipe the components on a conveyor belt, which transports them into the mixer.
  • Mobile scales are only accurate enough for larger target weights, fine weighing is not possible. Furthermore, the components must be removed individually and one after the other, which is correspondingly time-consuming.
  • the conveyor device has a mobile collecting container, the path of which extends over all weighing containers, and a drive control by means of which the traveling movements of the collecting container can be controlled in such a way that the collecting container reaches the weighing container in the order in which the target weight is reached and finally moves to a position for transferring the collected components to one of the mixers.
  • a collecting container which takes over the components from all weighing containers after the respective weighing process and delivers the collected components to the mixer after taking over the last weighed component.
  • the travel drive of the collecting container is controlled so that it moves to the individual weighing containers in the order in which the target weight is reached.
  • the component with the lowest weight is therefore taken over first, while at the same time the weighing of the other components is continued until the next component has reached the target weight and the corresponding weighing container is approached by the collection container.
  • the entire time for the longest weighing process is thus used to collect the weighed components during this period.
  • the collection container moves into a transfer position in which all of the components of a batch that have been picked up are delivered to one of the mixers.
  • a pneumatic or hydraulic cylinder can be provided as the positioning drive, which has fixed positions on the individual weighing containers, with only the sequence of moving to the individual positions being changed depending on the target weight being reached on the individual weighing containers in accordance with the desired recipe.
  • the weighing containers are arranged on an arm with a tilting drive which, when the target weight is reached and the collecting container is moved under, tilts the weighing container into the emptying position.
  • the tilt drive is on the one hand the target weight receiving sensor, on the other hand controlled by a position detector of the collecting container.
  • each weighing container with its tilting arm is guided by a parallelogram linkage which is received by the balance. In this way, the tilting moment of the weighing container does not affect the weighing.
  • the weighing container can be equipped with a mechanical loosening device, e.g. B. a vibrating or tapping device, provided to also sticky products such. B. completely empty pigments that do not flow out by tilting alone.
  • a mechanical loosening device e.g. B. a vibrating or tapping device, provided to also sticky products such. B. completely empty pigments that do not flow out by tilting alone.
  • This training initially has the advantage that the individual components get from the storage container in the shortest possible way into the metering screw in order to be discharged into the weighing container by the latter.
  • the closure arranged at the outlet of the dosing screw can fulfill two functions. On the one hand, it can be actuated when the target weight has been reached on the corresponding weighing container, so that the material flow is suddenly interrupted. On the other hand, by closing the drain, the dosing screw can be placed under vacuum or overpressure together with the storage container, in order in this way, for example, to enable the storage containers to be filled by suction or pressure delivery. It is therefore also expedient to flange-mount the dosing screw directly onto the outlet of the storage container.
  • a collecting container for receiving incorrectly weighed components can be arranged in the path of movement of the collecting container in order to be able to separate out such an incorrect batch in the same working cycle.
  • each storage container 1 can be seen, which hold a larger supply of the individual components.
  • the storage containers 1 are connected via a line 2 to a vacuum blower 3 and each have a filter 4 in their upper area.
  • Each storage container 1 is further provided with a component inlet 5, by means of which it can be filled from a tank truck or the like by means of the vacuum blower 3.
  • a motor-driven metering screw 7 is flanged to the bottom 6 of each storage container, which is optionally also equipped with a loosening device, the outlet 8 of which can be closed by means of a closure 9, which is controlled pneumatically, for example.
  • a weighing container 10 is arranged, which sits on a rotatably mounted tilting arm 11 and can be tilted downwards by 180 degrees from the filling and weighing position shown in the drawing.
  • the weighing container 10 sits together with the tilting arm 11 in a parallelogram linkage 12 by means of which it is guided in parallel in order to keep the weighing cell 13 free of tilting moments.
  • the collecting container can of course also be used to feed two or more mixers, the recipes and the sequence of the collecting container 15 being controlled according to the need for the mixers. Enough volume of an individual If the weighing container does not extend for the total weight of a component to be weighed, the collecting container 15 last moves to this position, takes over the first filling of the weighing container and then the remainder missing for the target weight.
