DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1 and FIG. 2, an automatic medicine packaging machine includes a plurality of tablet cassettes 3 arrayed in the interior of a body 2 and a door 4 established in each of the front and sides of the interior of the body 2 for opening and closing the body 2 and continuously packages each dose of medication by extracting tablets from the tablet cassettes 3.
The automatic medicine packaging machine includes a door lock unit 10 that is established in the front and sides of the body 2 of the automatic medicine packaging machine corresponding to the upper part of the door 4 and a button operation unit 20 that is established on the front of the body 2.
The door lock unit 10 automatically locks or unlocks the upper part of the door 4 by operation of a user.
The button operation unit 20 plays a role of inputting authentication information to authenticate a user of the door lock unit 10 by operation of a user and simultaneously inputs a locking or unlocking signal to lock or unlock the door 4 by the door lock unit 10.
The user authentication of the door lock unit 10 is done by authentication information, that is, personal identification numbers or passwords, inputted by the button operation unit 20, but various arts may be applied for authentication.
The user authentication of the door lock unit 10 is also done by a biometric identifier 21 that is established on the front of the body 2 and on a side of the button operation unit 20. The biometric identifier 21 is for smooth user authentication when a user forgot authentication information, in addition to the user authentication through the input of authentication information.
The biometric identifier 21 that plays the above-identified role may independently authenticate a user without being inputted by the button operation unit 20, which is an art of common knowledge for authenticating a user by recognizing human being like a fingerprint identifier which identifies a fingerprint of human being, an iris identifier which identifies an iris of human being, or a voice identifier which identifies a voice of human being.
The user authentication of the door lock unit 10 is also done by a card reader 22 that is established on the front of the body 2. The art of the card reader 22 is an art of common knowledge for authenticating a user by recognizing and reading Integrated Circuit (IC) card information inputted by a user.
The user authentication by the card reader 22 may be independently used without getting authentication information inputted by the button operation unit 20 or may be subsidiarily used in case of being forgotten authentication information, that is, personal identification numbers or passwords, which will be inputted to the button operation unit 20.
In the FIG. 1 there are a touch screen S which is a display apparatus and a label printer P which prints labels.
Referring to FIG. 3 and FIG. 4, the automatic medicine packaging machine includes the door lock unit 10 that locks or unlocks the door 4, the button operation unit 20 that operates the door lock unit 10, the lock controller 30 that controls the operation of the door lock unit 10.
The door lock unit 10 that is established in the body 2 and releasably locks the door 4 includes a driver 11 that is established in the body 2 corresponding to the upper part of the door 4 and controlled by the lock controller 30, an anchor member 12 that locks or unlocks the door 4 by being moved vertically by the driver 11, and a groove member 13 that is established on the upper part of the door 4 corresponding to the lower part of the anchor member 12.
If a user inputs a locking signal into the lock controller 30, then the lock controller 30 operates the driver 11 to insert the anchor member 12 into the groove member 13, and hence the door 4, on which the groove member is attached on the upper part, can be solidly fixed by the anchor member 12.
Conversely, if a user inputs an unlocking signal into the lock controller 30, then the lock controller 30 operates the driver 11 to pull the anchor member 12 out of the groove member 13, and hence unlocking of the door 4 can be accomplished by the anchor member 12.
The driver 11 can be embodied through a motor or a solenoid because the driver 11 can be operated to make the anchor member 12 vertically moved.
The door lock unit 10 further includes a manual operation unit 14 that locks or unlocks the door lock unit 10 by manual operation of a user during power failure.
The manual operation unit 14 allows manual operation of locking or unlocking of the door lock unit 10 by a user with a key in case of unexpected power failure in the automatic medicine packaging machine.
The manual operation unit 14 includes an on/off switch 141 that is established on the body 2 as a state of being connected to the driver 14, a battery 142 that is connected to the on/off switch 141 and provides power to the driver 14, and a key operation unit 143 that is exposed outside the body 2 and controls the driver's 11 operation of locking or unlocking by turning on/off power to be supplied to the driver 11.
When locking or unlocking of the door lock unit 10 may not be performed through the button operation unit 20 in case of power failure, following alternative steps may be sequentially proceeded: a user inserts and rotates a key into the key operation unit 143, power changes from off to on by the on/off switch 141, the door lock unit 10 operates to be unlocked in a state of power on, the door lock unit 10 changes from the operation of unlocking to locking, and finally the door lock unit 10 changes from the operation of locking to power off.
In other words, if a user operates the on/off switch 141 through the key operation unit 143 by inserting a key into the key operation unit 143, then the on/off switch 141 makes power on/off in between the rechargeable battery 142 and the driver 142 according to the rotating position of the key, or locking or unlocking of the door 4 may be manually performed by controlling operation of the driver 11.
The button operation unit 20 that is established on the front of the body 2 plays a role of outputting to the lock controller 30 by being inputted operation of a user, and a user inputs user authentication information through the button operation unit 20 and simultaneously inputs a locking or unlocking signal of the door lock unit 10 into the lock controller 30.
If authentication information is inputted into the lock controller 30 by the button operation unit 20, then an user authentication unit 31 authenticates a user by comparing and analyzing inputted authentication information and authentication information stored in advance.
As another tool of user authentication in addition to the button operation unit 20, a biometric identifier 21 does user authentication alternatively or in case of being forgotten authentication information. The biometric identifier 21 inputs biometric information like a fingerprint, an iris or a voice of a user into the lock controller 30, and user authentication will be performed by the user authentication unit's 31 comparing and analyzing inputted biometric information and biometric information stored in advance.
As still another tool of user authentication in addition to the button operation unit 20, a card reader 22 does user authentication alternatively or in case of being forgotten authentication information. The card reader 22 reads Integrated Circuit (IC) card information of a user, inputs into the lock controller 30, and then user authentication will be performed by the user authentication unit's 31 comparing and analyzing inputted card information and card information stored in advance.
The lock controller 30 includes the user authentication unit 31 which authenticates a user of the door lock unit 10 and controls operation of the door lock unit 10 according to a signal of locking or unlocking inputted by the button operation unit 20.
In other words, the lock controller 30 authenticates a user by confirming authentication information inputted by the button operation unit 20 through user authentication unit 31 and simultaneously locks or unlocks the door 4 by controlling the driver 11 of the door lock unit 10 according to a locking or unlocking signal inputted through the button operation unit 20.
The automatic medicine packaging machine further includes an open/close detection sensor 40 that is established on the body 2 corresponding to the door 4 and inputs into the lock controller 30 by detecting a state of the door's 4 being locked or unlocked.
The open/close detection sensor 40 is a kind of contact sensor which recognizes a state of being open or close of the door 4 through contact or separation of the door 4 established in the body 2 and the open/close detection sensor 40 enables more precise locking because operation of the door lock unit 10 is done in a state of the door's 4 complete closing.
The automatic medicine packaging machine further includes a display 50 that is established on the front of the body 2 and displays the door's 4 opening or closing state inputted from the lock controller 30.
The display 50 is controlled by the lock controller 30 and makes locking or unlocking operation of the door 4 performed more precisely and conveniently by letting a user smoothly recognize a state of locking or unlocking of the door 4 by displaying information detected by the open/close detection sensor 40, that is, a state of locking or unlocking of the door 4.
The display 50 may be independently established on the front of the body 2 or a touch screen which is already established on the front of the body 2 may play the same role.
The automatic medicine packaging machine further includes a beep generation unit 60 that is connected to the lock controller 30 and makes beep sound for warning in case of abnormal opening of the door 4.
The beep generation unit 60 generates a beep by operation of the lock controller 30 if separation of the door 4 is detected by the open/close detection sensor 40 when the door 4 is separated by an unauthorized user while the door 4 is locked after a locking signal's being inputted by a user.
In other words, the lock controller 30 judges a state of the door's 4 being abnormally opened by an authorized person according to present state and information of the open/close detection sensor 40, and the lock controller 30 operates the beep operation unit 60 to make a beep outside.
The automatic medicine packaging machine further includes a user's resumé storage unit 70 that is connected to the lock controller 30 and stores users' resumés which are authenticated by the user authentication unit 31 of the lock controller 30.
The user's resumé storage unit 70 forms resumés on the door lock unit's 10 users by sequentially storing information on users who are authenticated by the user authenticated unit 31 while being controlled by the lock controller 30.
The users' resumés that are stored in the user's resumé storage unit 70 will be displayed on the display 50 according to operation of a user through the button operation unit 20 and makes a user conveniently confirm users of the door lock unit 10.
The automatic medicine packaging machine further includes a printer 80 that is connected to the lock controller 30 and prints users' resumés stored in the user's resumé storage unit 70 according to a user's operation through the button operation unit 20.
The printer 80 may be independently established on the front of the body 2 or a label printer which is already established on the front of the body 2 may play the same role.
