In general, a single-dose medicament according to a patient's prescription may include various kinds and forms of medicines, and a medicament for a single dose is dispensed from the medicament dispensing box to be delivered to the patient.

A variety of medicines contained in a single basket are dispensed from a box containing each medicament according to a prescription of a patient and collected in a basket. The basket in which the medicines are collected is delivered to the patient, and the medicines collected in the basket .

On the other hand, in order to collect various medicines in one basket, in the past, medicines experts such as pharmacists needed a process of manually selecting medicines according to the patient's prescription, and accordingly, a confirmation operation to judge the accuracy of the medicament collection It was necessary. This makes it difficult to ensure the correctness of the medication and always implies the possibility of causing an attrition. In addition, not only the possibility of weakness but also the complexity of the collection process itself, it takes a long time to collect the medicine according to the prescription of the patient, which also causes a problem of lowering the working efficiency. For this reason, it is necessary to study methods and techniques for improving the accuracy and efficiency in collecting medicines for one dose according to the patient's prescription, thereby providing convenience to users such as pharmacists and preventing weakening accidents in advance Do.

On the other hand, in order to automatically dispense canned medicines, a technique of recognizing the perforated lines of the medicament package is required in order to separate each of the bound medicines. Conventionally, an ultrasonic sensor or the like has been used in addition to a camera for detecting a perforated line of such a package. However, in this case, there were many difficulties to include the perforating line detection technology due to the characteristics of the medicine dispensing box which is limited by limited space.

The present invention provides a method for detecting a perforation line of a drug package as a premise for individually cutting a drug package.

The present invention also provides a percutaneous line sensing method for minimizing system consumption of a computing device for image processing of a drug package.

The storage part 300 is formed in a wheel shape and is stored in a state in which the medicine package 2 is wound. The storage unit 300 includes a winding core 320 and a side case 310. The medicine package 2 is wound around the winding core 320 and unrolled by the transfer unit 400. [ The side case 310 serves to prevent the side face 320 from being deviated to the side when the package 2 is wound or unwound. Meanwhile, the storage unit 300 can be formed simply by a space portion in which the package can be stored. That is, it is also possible to provide a simple space by excluding constituent parts such as wheels in the storage part, and to simply fold the package of medicine into the formed space part.

The transfer unit 400 includes a pair of first rolls 410, a pair of second rolls 420, and a discharge roll 430. The pair of first rolls 410 includes a first upper roll 411 and a first lower roll 412. The first upper roll 411 is located at the upper portion of the first lower roll 412 and is provided to abut the first lower roll 412. The outer circumferential surfaces of the first upper roll 411 and the first lower roll 412 may be formed of an elastic material, in particular, a porous material. The outer circumferential surfaces of the first upper roll 411 and the first lower roll 412 are formed of an elastic material, so that the force for pressing the medicines in the package of medicine between the first roll 411 and the first lower roll 412 can be minimized. The first lower roll 412 in this embodiment is driven by a motor, preferably a stepping motor, and the first upper roll 411 rotates passively in accordance with the rotating direction of the first lower roll 412. The pair of first rolls 410 guides the package 2 in the direction of the discharge roll 430 in a state where the foremost end of the package 2 is initially positioned.

The pair of second rolls 420 transfer the front end of the package 2 to the discharge roll 430 side from the pair of first rolls 410. The pair of second rolls 420 includes a second upper roll 421 and a second lower roll 422. The second upper roll 421 is positioned above the second lower roll 422 and abuts the second lower roll 422. The outer circumferential surfaces of the second upper roll 421 and the second lower roll 422 may be formed of an elastic material, in particular, a porous material. The outer circumferential surfaces of the second upper roll 421 and the second lower roll 422 are made of an elastic material, so that the force for pressing the medicines in the package packaging interposed therebetween can be minimized. The second lower roll 422 in this embodiment is driven by a motor, preferably a step motor, and the second upper roll 421 rotates passively in accordance with the rotational direction of the second lower roll 422. The pair of second rolls 420 transports the frontmost end of the medicine package 2 toward the discharge roll 430.

Meanwhile, the first lower roll 412 and the second lower roll 422 are preferably driven by independent driving motors. The detection of the perforated line of the package 2 may not be easy when the package 2 is interlocked or loosened between the first lower roll 412 and the second lower roll 422. In this case, any one of the first lower roll 412 and the second lower roll 422 may be driven in the direction to generate tension in the package 2, thereby minimizing errors that may occur in detecting the perforated line. At this time, it is possible to apply an accurate tension by driving each roll using a step motor.

On the other hand, the first upper roll 411 and the second upper roll 421 are connected to each other by an elastic member 403. The first upper roll 411 and the second upper roll 421 are fixed by the elastic member 403 so that they have a constant operating range in the vertical direction and are lifted by the user at the initial setting of the package 2 or in the event of an error And even when the drug package 2 is transferred between the first roll 410 and the second roll 420, the force applied to the medicament contained in the medicament package 2 is minimized .

A discharge roll 430 may be provided at the distal end in the transport direction. The discharge roll 430 discharges the package 2 of the medicine delivered from the pair of second rolls 420 to the outside. The discharge roll 430 receives the driving force using the second upper roll 421 and a timing belt.

As shown in FIG. 5, a support 150 for supporting the package of the medicine delivered via the first lower roll 412 and the second lower roll 422. The drug package is transported while being supported by a transfer plate 151 formed in a flat plate shape on the upper end of the support part 150. [ At this time, the first lower roll 412 and the second lower roll 422 are exposed on the transfer plate 151. At the center of the transfer plate 151, a light transmitting member 152 is provided. The light transmitting member 152 transmits light emitted from the light source unit 500 provided below the light transmitting member 152. The light source unit 500 emits light using the light emitting device 510. The light emitted from the light source unit 500 is used as illumination when photographing the package of caps by a scanning unit to be described later. Meanwhile, the light source unit 500 may provide illumination by an indirect illumination method. In this embodiment, the light transmitting member 152 is used in indirect lighting. The light transmitting member 152 may scatter or diffuse light emitted from the light source unit 500 to uniformize the illuminance distribution and prevent light from being concentrated in other components. Unlike the present embodiment, the light source unit 500 may be provided with the light emitting device 510 facing downward so that the reflected light may be directed upward. The light source unit 500 in this embodiment is provided on the opposite side of the scanning unit, which will be described later, on the basis of the packaging package.

The scan unit and light blocking unit will be described with reference to FIGS. 6 to 10. FIG. FIG. 6 is an exploded perspective view of a medicine dispenser dispenser box according to an embodiment, FIG. 7 is another exploded perspective view of a medicine dispenser dispenser box according to an embodiment, and FIG. 8 is a cross- FIG. FIGS. 9 and 10 are schematic views showing operations of the scan unit according to an embodiment.

And includes a light blocking portion 160 as shown in FIG. The light shielding part 160 includes a light shielding part upper case 160a and a light shielding part lower case 160b as shown in FIG. The upper case 160a and the lower case 160b of the light shielding unit 160 form a predetermined space portion having a scan unit therein. 8, a scan window 161 is formed in the light blocking part lower case 160b. The scan unit, which will be described later, can photograph the package of the medicine under the scan window 161 through the scan window 161. At this time, the light shielding unit 160 prevents other light noise other than the image of the medicine package from flowing into the image. Further, a light absorbing layer (not shown) may be formed on the inner side of the light intercepting portion 160 to minimize reflection of light. At this time, a matte black coating layer may be used as the light absorbing layer. In addition, the upper constituent parts of the first upper roll etc. transfer part 400 are exposed to the light blocking part lower case 160b.

9 and 10, the scan unit 600 is disposed above the light transmitting member 152 and is transported onto the light transmitting member 152 from the storage unit 300, Quot;). At this time, it is preferable that the scanning unit 600 photographs the fusible package 2 with the fused portion formed at the time of sealing the package 2 as the center.

11 to 15, a perforated line sensing method of the drug package according to one embodiment will be described. FIG. 11 is a block diagram illustrating components associated with perforated line sensing of a drug package according to an embodiment, and FIG. 12 is a schematic diagram illustrating a schematic view of a drug package. FIG. 13 is a flowchart illustrating a perineal line sensing method according to an exemplary embodiment. FIG. 14 is a flowchart illustrating an image processing process according to an exemplary embodiment. FIG. 15 is a flowchart illustrating a perineal line sensing process according to an exemplary embodiment.

Referring to FIG. 11, as described above, the scan unit 600 photographs a continuous image of the medicine package 2 transported using the illumination provided by the illumination unit 500. At this time, the sensing unit 700 receives the continuous image photographed from the scan unit 600 and senses the perforated line. Hereinafter, a method of detecting the perforation line of the package 2 by the scan unit 600 and the sensing unit 700 will be described in detail.

First, as shown in Fig. 12, the medicine package 2 is generally manufactured by folding a sheet in half and then forming a heat-sealed portion A1 by thermal fusion and then forming a perforated line L1. And the medicament receiving portion A2 in which the medicines are accommodated inside by the thermally fused portion A1 is provided. At this time, the thermally fused portion A1 can be divided into the transverse direction fused portion A1a and the longitudinal direction fused portion A1b. The transverse thermal fused portion A1a functions to seal the mouth of the package 2 and the longitudinal thermal fused portion A1b functions to partition the medicament receiving portion A2 formed between the respective fingers . In the following description, for the sake of convenience, the intersection A2 of the transverse direction fused portion A1a and the longitudinal direction fused portion A1b, the transverse direction fused portion A1a, the longitudinal direction fused portion A1b, The inner intersection points P1a and P1b are used. The intersection A2 between the longitudinally welded portion A1a and the longitudinally welded portion A1b means a portion where the transverse direction welded portion A1a and the longitudinally welded portion A1b meet and cross each other, The inner intersection points P1a and P1b of the longitudinally welded portion A1a and the longitudinally welded portion A1b refer to the innermost intersections of the intersections A2 as shown in FIG. Also, when the package is transported in a certain direction (D1), the first inner intersection (P1a) and the second inner intersection (P1b) are divided according to the sequence taken by the scan unit.

The drug package perforated line sensing method according to the present embodiment includes an image acquisition step (S10), an image processing step (S20), and a perforated line sensing step (S30) as shown in FIG. In the image acquiring step (S10), an image including intersections of the thermally fused portions formed in the lateral direction and the thermally fused portions formed in the longitudinal direction of the package is obtained, and in the image processing step (S20) Image processing is performed as a preliminary step. In the perforated line sensing step S30, the perforated line of the package of the medicine is sensed using the image processed image.

At this time, if the perforated line is not sensed in the perforated line sensing step S30 (S40), the image acquisition step S10, the image processing step S20, the perforated line sensing step S30, .

Specifically, the image acquiring step includes: an image acquiring step of acquiring an image of the drug package; And an image acquiring second step of cutting out an image including an intersection of the transverse thermal fusing part and the longitudinal thermal fusing part of the package of the package in the image. That is, it is possible to reduce the size of the perforated line sensing target image by taking an image of the package medicine package using the camera, taking only the necessary portion, and discarding the remaining portion.

The package of the medicine is variously formed using a transparent material or an opaque material, but in the case of the heat-sealed part, the material is transparently changed due to fusion due to high temperature. Therefore, if the scan unit captures the image after providing illumination from the back side of the package of packages through the illuminating unit, the light and dark portions of the heat-sealed portion through which the light passes may greatly differ in contrast from the other portions.

In order to detect the intersection between the transverse fusing part and the longitudinal fusing part, there is a method of photographing an image by positioning the position of the scanning part at the corresponding position. After the image is taken, It is also possible to use a method of detecting the inner intersection of the fused portion and deducing the position of the intersection of the transverse fused portion and the longitudinal fused portion.

Referring to FIG. 14, the image processing process S20 converts the acquired image into gray scale in order to eliminate color information from the acquired image (S210). On the other hand, it is also possible to remove the noise of the image using a median filter as needed before conversion to grayscale.

Next, the image converted to gray scale is subjected to binarization processing so as to be converted into white and black only (S220). As a final step of the image processing, the edge of the binarized image is extracted (S230). The edge-extracted image is transformed so that the boundary between white and black is displayed in black. Furthermore, the noise cancellation can be performed by a median filter.

The perforated line sensing process can be performed in various ways. For example, a perforated line of a drug package can be extracted using an outline trace technique using an edge extracted image or a pattern recognition method.

In the case of the pattern recognition method, various known techniques are used to grasp the pattern of the black pixels in the extracted image, and when there is a linear pattern terminating the image in the image, pixels corresponding to the pattern are recognized as perforations . ≪ / RTI >

In the case of the outline tracing method, as shown in FIG. 15, a black pixel located at the uppermost end of the edge extracted image is searched (S310). When a black pixel located at the uppermost end is found, the surrounding black pixel is detected using the pixel as a reference pixel (S320). In this case, in the present embodiment, when the outline is traced downward in the image, it is determined whether there are surrounding black pixels in the clockwise direction from the 3 o'clock direction. If a black pixel exists in the vicinity (S340), the pixel is again used as a reference pixel (S345), and the surrounding black pixels are detected in the same manner. If there is no surrounding black pixel before reaching the lowermost end of the image, it is determined that the perforation line is not present in the image (S352), and the detection of the surrounding black pixels is repeated until the reference pixel reaches the lowermost end of the image , It can be determined that the perforated line exists in the image and that the movement path of the reference pixel corresponds to the perforated line. On the other hand, in the present embodiment, only the unidirectional tracking method from the upper part of the image to the lower part is used, but it is also possible to continue tracking from the lower part to the upper part. In this case, it is detected whether or not a pixel at 9 o'clock direction of the reference pixel is a black pixel. If the pixel does not have black information, it rotates along the clockwise direction and determines whether surrounding pixels have black information. If there is a black pixel in the periphery, the pixel is used as a reference pixel to determine whether or not the surrounding black pixel exists again.

In the case where the movement path of the reference pixel is linearly formed from the top to the bottom of the image by tracing the outline, it can be determined that the position of the movement path of the reference pixel corresponds to the position of the perforation line of the package.

A detailed description will be made with reference to FIG. As shown in FIG. 16A, a black pixel is detected at the top of the image first, and the corresponding pixel is set as a reference pixel. Next, the surrounding black pixels are detected clockwise from the pixels at the 3 o'clock direction of the reference pixel. In this case, as shown in FIG. 16B, since the immediately lower pixel is a black pixel, the reference pixel is moved to the lower pixel and the surrounding black pixel is tracked from the 3 o'clock direction clockwise. When the surrounding black pixels are traced in this manner, the reference pixel forms a path along the right outline of the black pixels to the bottom of the image as shown in FIGS. 6C to 6F. In this case, if the black pixels protruding in the lateral direction reach the transverse end of the image or fail to reach the lower end of the image, it is judged that the pixels are not perforated lines. In the case of FIGS. 16A to 16F, since there are black pixels that terminate the image, it can be determined as a perforated line. On the other hand, in order to increase the accuracy, the outline from the lower end portion to the upper portion can be further traced as shown in FIGS. 16F to 16K. In this case, it rotates clockwise from the pixel at 9 o'clock of the reference pixel and tracks the black pixel. As a result, when tracing the image from the bottom to the top, the left outline of the black pixels is traced. In this way, the outline of the pixels included in the image is traced to determine whether or not the movement path of the reference pixel ends the image, and the position of the perforation line is detected.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
