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 two or more mixers feeding conveyor.
  • the invention has for its object to develop the device mentioned in such a way that even with small and smallest batches within a recipe
  • the recipe can be exactly adhered to from a large number of components and can be produced in the shortest possible time and two or more mixers can be supplied by the device with possibly changing recipes.
  • 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.
  • the collection container is emptied in a very short time. During the movement in the over dispensing position and during emptying can already be weighed again, especially for a batch with a different recipe if necessary, in order to dispense the batch to another mixer after collecting these components.
  • the collecting container runs on a guide which extends below all weighing containers and can be moved by means of a positioning drive.
  • 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 respectively desired recipe.
  • the weighing containers are preferably mounted such that they can be tilted and can be tilted from a weighing position for receiving the components from the storage containers by 180 degrees into an emptying position above the collecting container.
  • the tilting of the weighing container has the advantage that the emptying can be carried out quickly and without further aids, such as loosening devices or the like, and that a residue-free emptying of the weighing container is also possible, which ensures high formulation accuracy.
  • 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 becomes the target weight-absorbing 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.
  • each storage container is assigned its own dosing screw, the drain above which is provided with a closure.
  • 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 11 by means of which it is guided in parallel in order to keep the weighing cell 13 free of tilting moments.
  • a guide 14 is arranged below the weighing container 10, which extends over all weighing containers 10 and on which a collecting container 15 can be moved in accordance with the indicated directional arrows.
  • the collecting container 15 has a closable outlet 16. It is by means of a drive, not shown, for. B. a pneumatic or hydraulic cylinder, from weighing container to weighing container and to the transfer position shown in the drawing, in which it is located above a container 17, to which in turn a mixer is connected.
  • the collecting container 15 moves into the position of the weighing container 10 that first reaches the target weight, that is, in which the smallest amount is weighed. When the target weight is reached, the tilt drive of this weighing container is put into operation, so that the weighing container is emptied into the collecting container 15. The collecting container 15 then moves the individual weighing containers in the order in which the target weight is reached there. If the collecting container 15 has taken up the last component, which is usually the one with the greatest weight, it moves into the transfer position shown in the drawing and releases the collected components to the container 17 after opening the closure 16. The next recipe can already be weighed again while moving into the transfer position and transferring to the container 17.
  • 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.
  • a collecting container can be provided along the guide 14 in a position corresponding to the container 17, in order to be able to empty the incorrect batch received by the collecting container 15 in the event of incorrect weighing, without disrupting the working cycle more than necessary.
