  • the controller 125 may be designed so as not to allow the opening of the first shutter 60 and stop the operation of the pharmaceutical packaging apparatus if the magnitude of the output signal is larger than the reference value CR.
  • the first shutter 60 is not automatically opened and the operation of the medicine packing apparatus is also stopped , The operator does not have to be burdened with the work of urgently stopping the medicine packing apparatus.
  • the piezoelectric plate 101 is installed on the inner space of the first medicine tank 11, that is, on the inner surface defining the first medicine space 12.

  • the installation height DH of the piezoelectric plate 101 is the height between the middle height MH and the lower limit height BH then the small particle medicament 2 having an amount smaller than the minimum allowable amount is applied to the first medicament space 12,
  • the difference between the size of the output signal in the case where the particulate agent 2 remains in the second chemical space 12 and the size of the output signal in the case where the small amount of the particulate agent 2 remains in the second chemical space 12 in an amount larger than the minimum allowable amount is not clearly revealed, The operator may not be aware that the medicament space 12 is empty. This is because the interference due to the small particle medicament 2 scattered in the first medicament space 12 is increased in the piezoelectric plate 101.
  • the small particle drug exhaustion notification device 100 automatically informs the operator of a small particle medicine (e.g., water) when the internal space 12 of the medicine tank 11 containing the small particle medicine 2, 2) should be supplemented. Therefore, the operator can appropriately replenish the small particle medicine (2) to the medicine tank (11), and work defects are prevented in the automatic medicine packing using the medicine packing apparatus.
  • the small particle drug exhaustion notification device 100 uses the piezoelectric plate 101 as a means for detecting whether or not the small particle medicine 2 is filled in the medicine tank 11. Therefore, the accuracy and the cost are reduced as compared with the case of using the photo sensor or the ultrasonic sensor.

Abstract

L'invention concerne un dispositif pour avertir d'une pénurie de granules de médicament, qui donne une alerte lorsque la quantité de granules de médicament remplissant l'espace interne d'un réservoir de médicament est inférieure à un niveau autorisé minimal prédéterminé. Le dispositif divulgué pour avertir d'une pénurie de granules de médicament comprend : une membrane piézoélectrique installée à l'intérieur d'un réservoir de médicament tout en étant exposé à des granules de médicament ; une unité d'alarme pour émettre une stimulation qui peut attirer l'attention d'un opérateur ; et un dispositif de commande qui applique une tension de type impulsion en tant que signal d'entrée sur la membrane piézoélectrique, et reçoit, en provenance de la membrane piézoélectrique, une tension de type impulsion en tant que signal de sortie en réponse au signal d'entrée, et active l'unité d'alarme lorsque la force du signal de sortie est supérieure à une valeur de référence prédéterminée.
