Description

{Cartridge base for medicine packing machine}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pharmaceutical packaging apparatus, and more particularly, to a cartridge for accommodating any one type of tablet and discharging the received tablet according to a prescription.

FIG. 1 is a schematic view of a conventional pharmaceutical packaging apparatus, and FIG. 2 is a perspective view of the tablet cabinet shown in FIG. 1. FIG.

Pharmaceutical packaging devices such as the one shown in Figure 1 are well known for automatically dispensing and dispensing pharmaceutical formulations in tablet form in accordance with a doctor's prescription. The pharmaceutical packaging apparatus comprises a tablet cabinet 10 in which various tablets are stored for each type and a packaging unit 20 for packaging tablets supplied from the tablet cabinet 10 below the tablet cabinet 10. The tablet cabinet 10 has a cabinet body 11 and a tablet container 12 as shown in Fig. The cabinet body 11 has a structure in which an internal space is formed and at least one side is opened. For example, the cabinet body 11 may have an empty box shape and an open side. The tablet container 12 has a structure in which a plurality of cartridges 13 can be mounted so that the cartridges 13 can be pulled out together in the process of being drawn out from the cabinet body 11. [ The cartridge 13 has a cartridge case 13a and a cartridge base 13b which is engaged with the lower end of the cartridge case 13a. The cartridge case 13a accommodates tablets of any one of various kinds of tablets. The cartridge base 13b controls the tablets contained in the cartridge case 13a to be discharged according to the preparation data received from the integrated control unit that integrally controls the drug packaging apparatus.

On the other hand, a technique of recognizing the mounting of the cartridge case in a contact manner on the cartridge base is well known. In the case of the contact type, the cartridge base recognizes the mounting of the cartridge case through the terminal contact. However, in the case of such a contact type, contact friction may cause wear of the terminal, resulting in poor contact. Therefore, a technology for recognizing the mounting of the cartridge case using the RF tag is well known in the Korean Patent Registration No. 10-0744427 for solving such a problem. According to this, an RF tag is attached to the cartridge case, and the cartridge base determines whether or not the cartridge case is mounted by reading the RF tag information. The RF tag method solves the problem of the contact type recognition method.

However, the conventional non-contact type is for recognizing whether or not the cartridge case is mounted, but for reading drug information stored in the RF tag of the cartridge case in a noncontact manner, and additionally recognizing whether or not the cartridge case is mounted. Even if the cartridge case is not normally mounted on the cartridge base, the tag reader can read the drug information stored in the RF tag if the RF tag of the cartridge case and the tag reader of the cartridge base are in a communicable area, There is a limit in ensuring the mounting of the cartridge case.

On the other hand, in Korean Patent Registration No. 10-0858218, a display unit is provided on a cartridge base on which a cartridge case is mounted. This display shows a unique identification number so that the administrator can identify the cartridge through the number displayed on this display. However, the display portion provided in the conventional cartridge base is a seven-segment display portion. Therefore, there is a limit to display information related to the cartridge.

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a view of a cartridge having a display unit according to an embodiment of the present invention, and FIG. 4 is a block diagram of a cartridge base according to an embodiment of the present invention.

As shown in FIG. 3, the cartridge is composed of a cartridge case 100 and a cartridge base 200. The cartridge case 100 receives one kind of tablet and is mounted on the cartridge base 200. The cartridge base (200) discharges the tablets contained in the cartridge case (100). Accordingly, the cartridge base 200 may be referred to as a tablet discharge unit. The cartridge base 200 includes a display unit 210, a main communication unit 220, a storage unit 230, a mounting sensing unit 240, and a control unit 250. The display unit 210 is a display device capable of displaying text and images, and examples thereof include LEDs (Light Emitting Diodes) and TFT-LCD (Thin Film Transistor-Liquid Crystal Display). The main communication unit 220 is configured to perform wired or wireless communication with the integrated control unit 300 for integrally controlling the pharmaceutical packaging apparatus in the pharmaceutical packaging apparatus. In order to ensure reliability of communication, the main communication unit 220 may be implemented by a wired communication method, and the wired communication method may be exemplified by a half-duplex communication method as a serial communication.

The storage unit 230 may be a nonvolatile memory, and the storage unit 230 stores programs and data necessary for controlling the overall operation of the cartridge base. In addition, drug information is stored in the storage unit 230. The drug information includes information on the name of the medicine, the drug code, and the number of tablets contained in the cartridge case 100. Further, the drug information may further include at least some of the drug barcode, the drug image, the expiration date, and the distribution period. The expiration date means the period during which the tablets are normally packaged at the time of first packaging, and the shelf life period refers to the period during which the packaged product is repacked after being unpacked to allow normal use of the newly defined drug.

Further, the drug information may further include three-dimensional shape information of tablets used to determine whether the tablets are discharged or not, and the color information of the tablets may be further included for the same purpose. The three-dimensional shape information includes at least one of length, width, and thickness information of the tablet. The shape of the tablets may be circular, rectangular, elliptical, or the like. Since the length, width, and thickness of the tablets vary depending on the shapes and sizes of the tablets, the three-dimensional shape information is easily used for distinguishing tablets . Likewise, color information of tablets can be readily used to distinguish tablets. The above drug information may be the information that the cartridge base 200 reads from the cartridge case 100. That is, the drug information is recorded in the memory of the cartridge case 100, and when the cartridge base 200 recognizes the mounting of the cartridge case 100, the drug information can be read in a contact or non-contact manner.

In addition, the storage unit 230 may further store various graphic data. For example, graphic data indicating that the quantity of tablets contained in the cartridge case 100 is sufficient and graphic data indicating that supplementation is necessary may be stored in the storage unit 230. [ Also, graphic data that may be displayed when the cartridge base 200 discharges the tablets may be stored in the storage unit 230, such as tablets, tablets, tablets, And the like. The graphical data indicating the tablets discharge means that the tablets are normally discharged, and the graphic data indicating the tablets overdischarge means that the tablets are discharged according to the preparation data in excess of the tablets to be discharged, and the graphic data indicating the tablets- Means that less than the amount of tablets to be discharged according to the preparation data. The lack of discharge purification means that the remaining amount of tablets contained in the cartridge case 100 is smaller than the amount of tablets to be discharged according to the preparation data and no tablets are contained in the cartridge case 100 .

The storage unit 230 may also store graphic data indicating the state of the cartridge base 200. The storage unit 230 may store graphic data indicating the state of the cartridge base 200, ), And the like. For reference, FIG. 5 shows some examples of graphic data. The first graphic data indicates that the amount of tablets contained in the cartridge case 100 is sufficient, the second graphic data indicates that the amount of the tablet is insufficient and needs to be replenished, Is not connected to the cartridge base 200. And the fourth graphic data indicates that the cartridge base 200 is in an abnormal operation state and the fifth graphic data indicates drug information (medicine name, capacity) for tablets accommodated in the cartridge case 100, The data indicates the remaining amount of tablets contained in the cartridge case 100. [

The mounting sensing portion 240 senses that the cartridge case 100 is mounted on the cartridge base 200. In one embodiment, the mounting sensing portion 240 is a proximity sensor. As a proximity sensor, a Hall sensor is exemplified. In this case, a magnetic body is formed in the cartridge case 100. Therefore, the mounting of the cartridge case 100 can be detected by the hall sensor. In another embodiment, the mounting sensing portion 240 is an optical sensor. An example of a photo sensor is a photo interrupter. In this case, the cartridge case 100 includes a limit guide having a structural shape for interruption. 6, the photo interrupter includes a light emitting portion (LED) 241 and a phototransistor 242. When the cartridge case 100 is mounted on the cartridge base 200, It is possible to detect an interrupt by the < / RTI > In yet another embodiment, the mounting sensing portion 240 may be a light receiving module that receives light. In this case, the cartridge case 100 is formed with a light emitting module and may conform to the IrDA standard. That is, the mounting sensing unit 240 may sense mounting of the cartridge base 200 using a non-contact optical system.

In yet another embodiment, the cartridge base 200 may recognize the mounting of the cartridge case 100 in a contact manner without using the mounting sensing portion 240. This is explained as follows. The control unit 250 applies power to the power terminal among the contact connectors with the cartridge case 100 as shown in FIG. When the cartridge case 100 is mounted on the cartridge base 200 and power is supplied to the memory in the cartridge case 100, the transmission line of the memory instantaneously changes to the HIGH state. The control unit 250 detects a change in the signal level of the communication terminal among the contact connectors and recognizes that the cartridge case 100 is mounted. If such a recognition method is applied, the mounting sensing unit 240 need not be separately configured.

The control unit 250 may be a micro control unit. The control unit 250 determines whether or not the mounting of the cartridge case 100 is detected by the mounting sensing unit 240 or the mounting of the cartridge case 100 by the above- And stores the drug information in the storage unit 230. Here, the memory of the cartridge case 100 may be an EEPROM (electrically erasable and programmable ROM). The control unit 250 reads the drug information from the memory of the cartridge case 100 electrically connected to the cartridge case 100 according to the mounting of the cartridge case 100, and stores the read drug information in the storage unit 230. As another example, the cartridge case 100 may include a non-contact type tag storing drug information. When the cartridge case 100 is mounted, the tag communication unit 260 reads the drug information stored in the non-contact tag of the cartridge base 200. The control unit 250 receives the read drug information and stores the read drug information in the storage unit 230 do.

On the other hand, the drug information read from the cartridge case 100 may be a medicine code for identifying the tablets contained in the cartridge case 100. In this case, the control unit 250 transmits the drug code and the identification information (CBID) of the cartridge base 200 through the main communication unit 220 to the integrated control unit 300 ). The integrated control unit 300 returns concrete drug information corresponding to the drug code to the cartridge base 200. [ Accordingly, the control unit 250 receives concrete drug information from the integrated control unit 300 through the main communication unit 220, and stores the specific drug information in the storage unit 230.

As another example, the cartridge case 100 does not include a memory or a non-contact tag for storing drug information, and includes a dip switch (DIP switch). The dip switch is used to manually set the drug code, and is made up of a series of on-off switches on the dip as is well known. The administrator can then set the drug code by operating these on-off switches. The control unit 250 recognizes the medicine code through a series of on-off setting values of the dip switch electrically connected according to the mounting of the cartridge case 100. When the drug code is identified, the control unit 250 transmits the drug code and the CBID to the integrated control unit 300 through the main communication unit 220 to request and obtain specific drug information.

Meanwhile, the control unit 250 performs dispensing-related control only when the mounting detection unit 240 recognizes the mounting of the cartridge case 100. That is, even if the control unit 250 receives the preparation data from the integrated control unit 300 through the main communication unit 220, the control unit 250 does not perform the control for discharging the tablets if the mounting of the cartridge case 100 is not recognized. In other words, the control unit 250 controls to discharge tablets contained in the cartridge case 100 according to the preparation data received from the integrated control unit 300 via the main communication unit 220 when the preparation data is received, The tablet discharge is controlled only when the mounting of the case 100 is recognized. By doing this, dispensing errors are prevented.

Further, the control unit 250 counts the number of tablets to be discharged when the tablets contained in the cartridge case 100 are discharged, and updates the information on the quantity of the drug information stored in the storage unit 230. In one embodiment, the control unit 250 can manage the information on the quantity by dividing the quantity of discharged material and the remaining quantity. Also, the control unit 250 may output at least a part of the drug information stored in the storage unit 230 to the display unit 210 and display the screen. For example, the control unit 250 may display the drug information on the drug name and the dose on the display unit 210 as shown in FIG. 8, and display the drug information indicating that the drug code and the remaining quantity are absent on the display unit 210 ). ≪ / RTI > The control unit 250 may read the drug barcode stored in the storage unit 230 and output the drug barcode to the display unit 210. The user can read the drug barcode with the scanner and obtain detailed information about the drug. If the quantity of the tablets contained in the cartridge case is equal to or larger than the reference quantity, the control unit 250 reads the graphic data indicating that the quantity of the tablets is sufficient, and outputs the graphic data to the display unit 210. If the quantity is less than the reference quantity Graphic data indicating that the quantity is insufficient can be read from the storage unit 230 and output to the display unit 210.

Also, the control unit 250 reads the corresponding graphic data among the graphic data indicating the discharge of the tablet, the discharge of the tablet, the discharge of the tablet, the discharge of the tablet, and the absence of the tablet, from the storage unit 230, . That is, the control unit 250 performs control for discharging the tablets according to the preparation data received through the main communication unit 220, and at the same time, displays the tablets discharged, purified excess discharge, lack of tablet discharge, And reads the corresponding graphic data among the graphic data from the storage unit 230 and outputs the same to the display unit 210. The control unit 250 may also store corresponding graphic data among graphic data indicating operation, communication error, power supply error, operation error, and mounting / dismounting of the cartridge case 100 according to the state of the cartridge base 200 230 and output it to the display unit 210.

Furthermore, the cartridge base 200 may further include a tablet detection unit 270. The tablet detection unit 270 detects the tablets discharged through the cartridge base 200 two-dimensionally. To this end, the tablet detection unit 270 detects the discharge tablets using the photosensor array. The optical sensor may be an infrared (IR) based sensor, an ultrasonic based sensor, or a laser based sensor. The tablet detection unit 270 includes a transmission array 271, a reception array 272, a filter unit 273, and a signal conversion unit 274. The transmission array 271 is configured such that the light emitting elements are arranged, and the reception array 272 is configured such that the light receiving elements corresponding to the light emitting elements are arranged. As is well known, the filter unit 273 filters the signal output from the light receiving elements constituting the receiving array 272 to a specific wavelength band, and the signal converting unit 274 converts the filtered analog signal into a digital signal . In addition, the tablet detection unit 270 may include a color sensor for detecting the color of the tablet.

FIG. 10 is a schematic view of a cartridge base according to an embodiment of the present invention, FIG. 11 is a view showing the arrangement of a sensor array around an outlet according to an embodiment of the present invention, and FIG. FIG. 13 is a view showing a change in the detection of purification in the case of debris. FIG.

The arrangement of the sensor array, i. E., The transmit array 271 and receive array 272, is illustrated in Figs. As illustrated, the transmit array 271 and receive array 272 are disposed around the outlet 280 of the cartridge base 200. For example, if the outlet width is 50 mm and the length is 600 mm, 120 sensors should be placed in 10 longitudinal directions with a minimum width. 10, the transmit array 271 includes a first transmit array 271a that transmits a first array signal onto an outlet 280 and a second transmit array 271b that transmits a second array signal And the receive array 272 is comprised of a first receive array 272a that receives the first array signal and a second receive array 272b that receives the second array signal. To this end, the first transmission array 271a and the first reception array 272a are positioned to correspond to each other, and the second transmission array 271b and the second reception array 272b are positioned to correspond to each other. The first transmission array 271a and the first reception array 272a are arranged on the X axis and the second transmission array 271b and the second reception array 272b are arranged on the Y axis will be. That is, the direction of the first array signal and the direction of the second array signal are arranged at right angles. This is to enable two-dimensional detection of whether or not the tablet is discharged.

In addition to the two-dimensional detection, the transmission array 271 periodically transmits a signal according to a predetermined timing, so that the reception array 272 periodically receives signals. When the tablet is discharged through the outlet 280, however, some transmission signals of the transmission array 271 are not received by the reception array 272. And such a phenomenon is changed while the tablets pass through the detection target area on the discharge port 280. [ For example, in the case where the tablet is circular, the sensing change with respect to the sensing target area may be the same as in FIG. 12 (a) according to the passage of time. In the case where the tablet is rectangular, it may be as shown in Fig. 12 (b). 13 (a), 13 (b), and 13 (c) show examples in which debris is detected rather than tablets.

The control unit 250 estimates the three-dimensional shape by the sensing data of the tablet sensing unit 270 according to the tablet discharge, and determines whether or not the tablet is actually discharged based on the predicted shape. Specifically, the control unit 250 can estimate the three-dimensional shape using the optical transmission time interval information and the sensing data of the tablet sensing unit 270. This can be sufficiently predicted from the change of the two-dimensional sensing data with the passage of time as shown in FIG. For reference, the two-dimensional sensing image data is expressed by Equation (1) when t = 0, and the three-dimensional shape image data is represented by Equation (2).

The controller 250 acquires the three-dimensional shape information through the calculation for the three-dimensional shape prediction. At this time, the three-dimensional shape information includes at least one of length, width, and thickness information of the shape. The control unit 250 compares the obtained three-dimensional shape information with the three-dimensional shape information stored in the storage unit 230 to determine whether they are the same. If the color information is included in the sensed data, the controller 250 further compares the sensed color information with the color information stored in the storage unit 230 to determine whether they are the same. The error range can be set when comparing the same. If the result of the comparison is the same, the controller 250 determines that the tablet of the corresponding type is discharged. However, if it is determined that they are not the same, the controller 250 determines that the tablet of the corresponding type is not discharged. In this case, the control unit 250 may output the display data for informing the display unit 210 of the information. The control unit 250 also outputs a notification signal to the integrated control unit 300 through the main communication unit 220. This may be to cause the integrated control unit 300 to notify the manager of abnormal discharge of tablets through output of a notification sound or screen output. In addition, the control unit 250 may compare the number of discharged tablets detected by the tablet detecting unit 270 with the number of discharged tablets contained in the prescription data to determine whether they are the same. If not, the control unit 250 may output display data for informing the display unit 210 of the fact and may output a notification signal to the integrated control unit 300 through the main communication unit 220.

FIG. 14 is a diagram showing transmission timings and reception timings of a sensor array according to an embodiment of the present invention. FIG.

In the illustrated example, D_on indicates reception in a state that the LED is on, and D_off indicates that reception light is detected in a state where the LED is off. When the light amount is more than a certain amount when D_off is D_off, the controller 250 determines that the light is a disturbance light or a malfunction, and notifies the manager of the occurrence of an error. That is, when the control unit 250 does not transmit light from the transmitting LED but detects a certain amount of light through the corresponding receiving LED of the transmitting LED, the controller 250 informs the manager of the occurrence of the error. Here, as a notification method, a screen output or a warning sound output may be used.

The control unit 250 controls the light intensity of the transmission LEDs constituting the transmission array 271 and determines whether or not the operation of the purification sensor 270 is abnormal through the reception of the reception LEDs constituting the reception array 272 can do. For example, when the transmission LED is turned on but no light is received by the reception LED, the controller 250 may determine that the transmission LED has a weak light intensity, thereby increasing the light intensity of the transmission LED. However, if light is not received by the receiving LED even though the light intensity of the transmitting LED is adjusted as described above, the controller 250 determines that the transmission LED has failed or has reached the end of its life, and informs the manager thereof. For reference, since light is not received from some receiving LEDs at the time of discharging the tablets, it is preferable to adjust the light intensity of the transmitting LEDs when such a phenomenon continues for a certain period of time, that is, for a predetermined period of time.

15 is a first exemplary view of a sensor array driving method according to the present invention.

For convenience of explanation, it is assumed that the optical transmission diodes D1, D2, D3, D4, and D5 and the light receiving transistors TR1, TR2, TR3, TR4, and TR5 have five, respectively. The light is sequentially turned on from D1 to D5 and the light is transmitted to the predetermined time points T1_0, T1_1, T1_2, T1_3, and T1_4. And all the transistors TR1, TR2, TR3, TR4, and TR5 remain on. At this time, there is a time gap between on-switching of each diode. That is, there is a time gap between T1_0 and T1_1, between T1_1 and T1_2, between T1_2 and T1_3, and between T1_3 and T1_4. In fact, all the transistors are turned off in the gap period. The reason why the optical transmission time intervals of the diodes are made different from each other is to prevent reception errors due to the adjacent light. However, if there are many sensor arrays, diodes that are separated from each other can be driven simultaneously so that there is no fear of receiving errors. The control unit 250 can control the transmission array 271 and the reception array 272 as shown in FIG.

16 is a second exemplary view of a sensor array driving method according to the present invention.

The optical transmission time period of the diode is the same as that of the example of Fig. 15, and the transistor is turned on only during the ON time period of the corresponding diode. That is, only TR1 corresponding to D1 is turned on when Dl is turned on, only TR2 corresponding to D2 is turned on when D2 is turned on, only TR3 corresponding to D3 is turned on when D3 is turned on, D4 Only TR4 corresponding to D5 is turned on. When D5 is turned on, only TR5 corresponding to D5 is turned on. In this way, power dissipation can be prevented when the number of sensor arrays used for tablet detection is large. The control unit 250 can control the activation of the light emitting elements constituting the transmission array 271 and the activation of the light receiving elements constituting the reception array 272 according to a predetermined rule as shown in FIG.

17 and 18 are a third example and a fourth example of the sensor array driving method according to the present invention.

The same as in the example of Fig. 16, but the adjacent transistor of the transistor that is turned on is also turned on. This takes into consideration the case where light is received from the adjacent transistor due to the width of transmission light. When the sensor array is driven as in the example of FIGS. 17 and 18, the sensitivity can be increased. The control unit 250 can control the activation of the light emitting elements constituting the transmission array 271 and the activation of the light receiving elements constituting the reception array 272 according to a predetermined rule as shown in FIG. 17 or FIG.

19 and 20 are a fifth example and a sixth example of the sensor array driving method according to the present invention.

Some diodes of all the diodes are simultaneously turned on to transmit light and the corresponding transistors are turned on to receive light. If there are many sensor arrays, it is necessary to allocate different time intervals to transmit light. Thus driving some diodes simultaneously. This can shorten the time required for tablet detection. Also, by driving only the corresponding transistor, it is also possible to prevent waste of electric power. The control unit 250 can control the activation of the light emitting elements constituting the transmission array 271 and the activation of the light receiving elements constituting the reception array 272 according to a predetermined rule as shown in Fig. 19 or Fig.

21 is a seventh illustrative view of a sensor array driving method according to the present invention.

Some diodes of all the diodes are simultaneously turned on to transmit light and the corresponding transistors and transistors adjacent thereto are turned on to receive light. That is, the driving method of FIG. 21 is a combination of the driving method of FIG. 17 and the driving method of FIG. By doing so, the time required for detecting the tablets can be shortened, waste of electric power can be prevented, and light sensitivity can be increased. The controller 250 can control the activation of the light emitting elements constituting the transmission array 271 and the activation of the light receiving elements constituting the reception array 272 according to a predetermined rule as shown in FIG.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
