Definitions

  • the invention relates to a method for automatically calibrating a control of a device for supplying pets with a foodstuff, or its components from storage containers, possibly via a mixing container or directly to a removal point.
  • the present invention is based on the object
  • the solution to this problem is that a control is used to determine at intervals the amount (volume and / or weight) of the food or a certain food component in the mixing container or directly to the tapping point and an adjustment if the value changes compared to a desired amount the quantity is added to the desired value.
  • the basic idea of the present invention is that at certain intervals, whether triggered by the Operating personnel themselves or by means of a corresponding impulse in the control, a determination of the amount of food or its components during or when the automatic feeding of feed to the removal point is interrupted or the common addition of all food components to the mixing container. Instead, the food or the food components are fed to the tapping point or the mixing container in a controlled manner. At the same time, it is determined what time a certain amount (weight and / or volume) of food or food ingredients takes. If this time differs from a time previously specified in the control system, the old value is replaced by the new calibration value.
  • a portioning device can also be monitored.
  • a food or a food component is fed, for example, through a metering screw to the mixing container or the removal point. The amount of one is known
  • this value can also change significantly if, for example, food deposits on the screw. Therefore, from time to time, the amount that is actually in the removal point or the mixing container for a given rotation of the screw should be determined. If this value deviates from the specified value, the action of the portioning device must be changed, for example the rotation of the dosing screw must be increased or decreased.
  • Portioning devices are used. This includes not only the dosing screw, but also a dosing wheel, a rotary valve, vane wheels and a conveyor belt Sliders, dosing pumps, etc.
  • the portioning can take place according to various, adjustable setting parameters, such as, for example, time, step, pressure, speed, cross section, discharge speed, etc. There should be no limit to the present invention.
  • Difficulties can arise with food ingredients that are only added in very small amounts, such as medical ingredients. These medical ingredients can be added in 10th gram, with a scale, for example, measuring the weight only in grams.
  • a scale for example, measuring the weight only in grams.
  • the addition of food to the animal can be stopped during the calibration process and during the other quantity acquisition. Furthermore, the system is reset to zero after each output.
  • the calibration process can also take place during feeding, especially if it takes too long and the feeding process would be disturbed. For example.
  • a quantity and / or a weight of a food or food component can be determined in succession for each portion preparation, added up and divided by the number of portions.
  • the calibration can be carried out fully automatically, for example by specifying times in the control system in which the calibration takes place.
  • the controller can also contain a frame that specifies how often the calibration has to be repeated if detected deviations lie within or outside the frame.
  • the calibration is also carried out semi-automatically, ie depending on Request is initiated by the operating personnel. This is especially important when the farmer uses new feed, which requires a basic calibration.
  • the farmer has the option of manually starting the calibration process by pressing the corresponding button.
  • a scale should be assigned to the mixing container or the tapping point, which can be used to determine the weight of the individual food components. If the determination of the food component can be determined using other parameters, such as, for example, the fill level of the tapping point or the mixing container, these values are of course used as the basis for the calibration. In this case, the determination is made via a level sensor or light sensor. Detection by ultrasound is also considered.
  • Determining the amount of food ingredients has other advantages. It happens that an animal does not drink all of the mixed amount intended for it, but only part of it. By determining the amount of food, be it based on the weight or on the level, it can now be determined how much the animal has actually drunk or eaten. Furthermore, the rest of a subsequent animal is generally removed from the removal point or the mixing container, so that the additional quantity taken up by it can also be determined for this animal. Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
  • Figure 1 is a schematic representation of an inventive device for the care of pets
  • FIG. 2 shows a schematic illustration of a further exemplary embodiment of a device according to FIG. 1.
  • a mixing container 1 is indicated by an automatic feeder in FIG. 1, to which in turn five storage containers 2.1 to 2.5 are assigned. These storage containers 2.1 to 2.5 each contain food components, for example milk powder, medicine, pure milk or even water, it being possible for all possible sources of the food components to function as storage containers.
  • a storage container is also understood to mean, for example, a normal supply line for water from a water connection.
  • the food from the different food ingredients is then mixed together in the mixing container 1 and fed to a removal point 3.
  • This can be a suction part, but also, for example, a trough or the like.
  • a scale 4 or a level meter or any device for determining the amount of the food component, which is connected to a controller 5, is assigned to the mixing container 1.
  • the portioning devices 6.1 to 6.5 are also connected to the controller 5, it being determined how much of a food component has reached the mixing container 1 from the storage container 2.1 to 2.5. For example. this can be done by counting the revolutions of a screw.
  • the food components are also predetermined for a particular calf, so that, for example, the addition of pure milk or medicine can vary per calf.
  • the additions of the food components should be calibrated from time to time. This can happen, for example, once a day, a week or after a predetermined amount of dispensed portions.
  • the scale 4 is set to zero for calibration. A predetermined amount of water is now supplied to the mixing container 1 separately from the other food components. This is the first calibration value.
  • This process is carried out for each food component, so that the exact number of revolutions which are required for dispensing and transferring a specific amount of the specific food component in each case can be stored in the controller 5. If the values deviate from the desired values, the selection of revolutions or partial revolutions is increased or decreased.
  • the device according to the invention is now switched back to automatic operation, but the calibration values now allow the exact amount of food components to be added to the mixing container 1.
  • FIG. 2 a simple exemplary embodiment is also indicated, in the case of concentrated feed from a storage container
  • a controller 5 determines the rotation of the screw, while a scale 4 can determine the weight of the concentrate, which is present in the tapping point 3.
  • a level sensor or the like may be provided instead of a balance.
  • the controller 5 determines the actual weight of the concentrate fed from the screw 6.6 at the removal point 3 and relates it to the number of revolutions of the screw or the partial revolutions. If the desired value is not reached, the number of revolutions of the screw 6.6 is increased or decreased. As a rule, this should already be done by increasing or decreasing partial revolutions.

Abstract

L'invention concerne un procédé pour le calibrage automatique d'une commande d'un dispositif pour l'approvisionnement d'animaux domestiques en un aliment qui arrive ou dont les constituants arrivent, en provenance de réservoirs de stockage (2.1 à 2.6), directement ou éventuellement par l'intermédiaire d'un réservoir de mélange (1) à une station de prélèvement (3). Dans le procédé selon l'invention, une quantité (volume ou poids) de l'aliment ou d'un constituant précis de l'aliment arrive directement dans le réservoir de mélange (1) ou à la station de prélèvement. En cas de variation de la valeur par rapport à une quantité désirée, l'excédent de quantité est adapté à la valeur désirée.
