In the step of performing backup operation, medicine packing is performed according to the backup file(s) stored in the storage unit.


In the step of performing backup operation, whether there is a backup file in the storage unit is searched. If there is no backup file in the storage unit, new prescription data are input from a server computer. If there are one or more backup files found by the search, a situation, in which packing is performed in continuation to a packing just before the power failure, is displayed on a server computer.


The present invention also provides an apparatus for backing up power failure for an automatic medicine packing machine having a plurality of tablet cassettes that contain medicine, a printing unit that prints data on packing envelopes that contain medicine and a sealing unit that seals the packing envelopes. The apparatus includes a controller for the automatic medicine packing machine, which controls the tablet cassettes, the printing unit and the sealing unit of the automatic medicine packing machine according to prescription data that are input from a server computer, a storage unit that is connected to the controller and stores backup files that are input into the controller and a power recovery detecting unit that detects power recovery after power failure in the automatic medicine packing machine.


The controller creates backup files with the prescription data that are input from the server computer, stores them in the storage unit, and loads the backup files and performs packing operation according to the backup files stored in the storage unit when power recovery is reported from the power recovery detecting unit.


The power recovery detecting unit detects voltage applied to the controller.


The controller comprises a backup file creation module that arranges the prescription data input from the server computer in preparation order, classifies the prescription data for each packing unit, creates a backup file for each classified packing unit, and stores the created backup files in the storage unit, and a backup file deletion module that deletes the backup file, for which corresponding medicine has already been packed, for each packing unit.


The controller further comprises a backup file search module that searches whether a backup file exists in the storage unit after power recovery is reported from the power recovery detecting unit. If a backup file is not found, a new prescription data is requested to the server computer, and if one or more backup files are found, the searched backup files are loaded promptly to the controller.


The controller further includes a continued packing display module that displays continued packing status on the server computer when a backup file is found by searching with the backup file search module.


The storage unit comprises a hard disk drive.


The advantages of the present invention are: (1) duplicate medicine packing due to power failure and recovery is prevented in advance; (2) stable and precise packing is continued after power recovery; (3) delay due to duplicate packing is prevented; (4) the apparatus has a simple structure facilitating its installation and setting; (5) storing prescription data is conveniently performed with backup files; and (6) deleting backup files for which packing have been completed makes searching and loading of backup files easy and precise.

DETAILED DESCRIPTION OF THE INVENTION


FIG. 1 shows a method for backing up power failure for an automatic medicine packing machine. The method includes step S1 of creating backup file, in which a backup file is created from a prescription data, step S2 of storing backup file, in which the backup file created in step S1 is stored, step S3 of deleting backup file, in which the backup file for which packing of corresponding medicine is completed is deleted, step S4 of detecting power recovery, in which power recovery after power failure is detected, and step S5 of performing backup operation, in which backup operation of the automatic medicine packing machine is performed when power recovery is detected. These steps are performed sequentially and enable stable operation of medicine packing when the power is restored.


In step S1, when prescription data are input with a server computer to a controller, the controller arranges the prescription data in preparation order, classifies the data with each packing unit, and creates a backup file for each packing unit. Preferably the packing unit is a unit classified for each patient. In other words, the prescription data are classified for each patient, and the backup file is created for each patient.


In step S2, the backup file created in step S1 is stored in a separate storage unit that is electrically connected to the controller. In this way, even if prescription data that is input in the controller is lost by power failure, the controller can use the backup file stored in the storage unit.


In step S3, the controller deletes the backup file for the medicine that has already been packed during the operation of the automatic medicine packing machine. Among a plurality of backup files, the backup file, for which packing has been completed, is deleted so that the controller retrieves remaining backup files when a power failure and a subsequent power recovery occur and operate the packing machine according to the remaining backup files. In this way, seamless operation of medicine packing that is continuous from the operation before power failure.


In step S4, a power recovery detecting unit detects power recovery, when a power failure occurs during operation of the automatic medicine packing machine and then power is recovered. The moment of power recovery is detected and reported to the controller so that the controller recognizes the timing of using the backup files.


In step S5, operation of packing medicine according to the backup files stored in the storage unit is performed when power recovery is reported in step S4. When the controller searches backup files in the storage unit, if there is no backup file in the storage unit, new prescription data are input from the server computer. In this way, prompt operation of the packing machine is facilitated. If there are one or more backup files found by the search, the situation is displayed on the server computer so that a user can easily recognize that the automatic medicine packing machine is packing medicine following the packing operation just before the power failure.


Referring FIG. 2, an apparatus for backing up power failure for an automatic medicine packing machine includes a controller 10 of an automatic medicine packing machine 1, which controls tablet cassettes, a printing unit and a sealing unit of the automatic medicine packing machine 1 according to prescription data that are input by a server computer S; a storage unit 20 that stores backup files that are input by the controller 10; and a power recovery detecting unit 15 that detects power recovery after power failure in the automatic medicine packing machine 1.


The controller 10 creates backup files with the prescription data that are input from the server computer, stores them in the storage unit 20, and loads the backup files and performs packing operation according to the backup files stored in the storage unit 20 when power recovery is reported from the power recovery detecting unit 15.


The controller 10 further includes a backup file creation module 11 that arranges the prescription data input by the server computer in preparation order, classifies the prescription data for each packing unit, creates a backup file for each classified packing unit, and stores the created backup files in the storage unit 20.


The controller 10 further includes a backup file deletion module 12 that deletes a backup file, for which corresponding medicine has already been packed, for each packing unit.


The controller 10 further includes a backup file search module 13 that searches whether a backup file exists in the storage unit 20 after power recovery is reported from the power recovery detecting unit 15. If a backup file is not found, a new prescription data is requested to the server computer. If one or more backup files are found, the searched backup files are loaded promptly to the controller 10.


The controller 10 further includes a continued packing display module 14 that displays continued packing status on a monitor for the server computer when a backup file is found by searching with the backup file search module 13. In this way, the user can recognize that the packing is continuous before and after a power failure, an erroneous duplicate input of prescription data is prevented.


The storage unit 20 may utilize various storage devices including a hard disk drive, which can store mass data stably and easily and allows easy loading and deletion of files.


The power recovery detecting unit 15 has a role of informing the controller 10 that power is recovered in the automatic medicine packing machine 1 after power failure, and is preferably implemented as a constant voltage circuit that senses voltage that are supplied to the controller 10.
