Description

  The present invention relates to a tablet counting inspection apparatus that picks up and counts the packaged tablets without taking them out of the package, and more particularly to a tablet counting inspection apparatus that transports and continuously processes a strip of wrapped packaging paper.

  Based on prescription information, etc., the tablets are divided into sealed papers one after the other and installed adjacent to the tablet packaging machine that continuously forms the packaging of the tablets (packaging). There is known a tablet counting inspection device that receives images of each packet in order and automatically confirms the number of agents in each packet (see, for example, Patent Document 1). The number of agents in the package is automatically measured, and the count result is matched with prescription information and the like to automatically determine whether or not there is excess or deficiency.

  By the way, in tablet counting based on such imaging, even if the same tablet is packaged, the image obtained differs depending on the state of the tablet contained in the package, which affects the accuracy of the counting. In the case of tablets that cannot be separated, counting is lost, so that an image can be displayed on a display or the like and visually checked by an inspection operator. For example, when the number of prescription agents and the counting result are different, an alarm is issued to prompt visual confirmation of the display image.

  However, if the frequency of visual confirmation is high, the effect of automation by the tablet counting inspection device is diminished. The automatic processing is interrupted and the throughput is reduced, and the operator is burdened. For this reason, it is required to eliminate the overlap of tablets in the package. However, since it is not desirable to increase the cost including not only the manufacturing cost but also the maintenance cost, it is desirable to avoid adding complicated mechanisms and methods as much as possible. Therefore, a simple tablet counting inspection apparatus has been developed that captures images after spreading the tablets in a package.

  In other words, the pre-processing method that makes it possible to separate the state of the tablets contained in the wrap without separating the wrapping prior to imaging (a state in which stacking or aggregation has been eliminated) is easily realized with the clamp mechanism and the vibration mechanism. This is a tablet counting inspection device that images a packet of wrapping paper, etc., and automatically checks the number of agents in the package, and a clamp mechanism that temporarily presses the end of the packet, An excitation mechanism that vibrates the package and a transfer mechanism that transfers the package to the operation position of the clamp mechanism and the excitation mechanism are incorporated (for example, see Patent Document 2).

In such a tablet counting inspection apparatus, the performance of counting tablets based on imaging is improved, and accordingly, it is possible to perform continuous and continuous counting audits while transporting the wrapping paper. Thus, the processing efficiency is improved.
However, if the continuous transfer distance of the wrapping paper is increased or the transfer speed of the wrapping paper is increased, the undesired effect that the characteristics of the wrapping paper that wraps the medicine has on the transfer state becomes stronger. Different measures are required to further improve efficiency and utilization.

  In other words, if the medicine is introduced at the time of packaging, the packet expands, but since the amount of the medicine is not constant, the way the package swells is not determined, and the package is neither in the thickness direction, in the width direction nor in the length direction. Because it deforms variously, the wrapping paper twists and swells. Therefore, even if the twist is locally subtle, depending on the transfer distance and transfer speed, the effect of the twist is accumulated and amplified, resulting in transfer failures and transfer failures such as jamming and misalignment. . In order to further improve the efficiency and operating rate by lowering the frequency of occurrence of such problems, it is important to take measures to stabilize the transfer state. It is conceivable to introduce means for eliminating the twist of the transported wrapping paper.

However, since the twisting method is not constant as described above, the twisting of the wrapping paper cannot be sufficiently eliminated by adding a fixed guiding means such as a mechanical guide. Therefore, we want to detect the twisted state of the wrapping paper and actively and actively eliminate the twist, but simply use a detection member that can accurately detect the various twisted states of the wrapping paper that is soft and easily deformed. If it is added, even if remodeling is easy, it cannot withstand the rise in material costs.
Therefore, it becomes a technical problem to enable twist detection and twist elimination of the wrapper paper while suppressing an increase in cost by effectively using existing parts based on the characteristics of the wrapper paper.

The tablet counting inspection device of the present invention was created to solve such a problem, and images a series of packets separated by perforations on a wrapping paper and automatically confirms the number of agents therein. In the tablet counting inspection apparatus, an inclination detecting means for detecting an inclination of the perforation or an equivalent thereof based on the imaging data, and the inclination based on the detection (that is, the inclination of the perforation or the equivalent) A transfer mechanism that changes the transfer direction of the wrapping paper in the direction of eliminating the wrapping paper, and a spread mechanism that spreads the medicine therein by applying a mechanical action to the wrapping is provided upstream of the imaging position, The transport mechanism can also reversely feed the wrapping paper. Further, when the state of the tablets contained in the wrapping cannot be separated in the image, the wrapping is returned to the spread mechanism to retry from the spread process. become Characterized in that that.

  Here, "equivalent perforation" is one that tilts together with the perforation as the wrapping paper twists, and can perform image extraction and tilt detection from the image data of the hull as with the perforation. For example, marking lines printed parallel to the perforations, marking lines printed near both ends of the perforations, different area boundaries such as color and shading, etc., parallel to the perforations, etc. Is mentioned. Further, the “tilt” is measured based on the state when the wrapping paper is straightly stably transferred without being twisted.

  .

In the tablet counting auditing apparatus of the present invention includes a characteristic that perforations in the package paper attached mostly tilts along with the twisting of the packing paper, when imaging the wrap in the end region of the image Based on the characteristic that the perforation is reflected, the inclination or equivalent inclination of the perforation is detected from the imaging data of the packet, and the inclination is eliminated by changing the transport direction of the wrapping paper according to the inclination. As a result, it is possible to detect the tilt necessary for eliminating the twist by modifying the software without adding hardware for detection. Therefore, it is possible to detect twisting of the wrapping paper and eliminate twisting while suppressing an increase in cost.
Therefore, according to the present invention, it is possible to provide a tablet counting inspection apparatus with good efficiency and availability at low cost.

Moreover , in the tablet counting inspection apparatus of the present invention , the spreading mechanism is provided upstream of the imaging position, the transfer mechanism is capable of reverse feeding of the wrapping paper, and the tablet accommodation state in the wrapping is further provided. by the when that can not be sorted in the image you to retry from the spread out processing to return the package of corresponding to the place of diverging mechanism, the most to improve the separation ability and counting ability and audit capability, so the package paper When going back and forth, the wrapping paper tends to be deformed severely, and that alone will increase the frequency of transfer failures and transfer failures such as jamming and misalignment. Combined with measures for detecting and twisting paper, it is possible to increase the accuracy of counting without reducing the efficiency and operating rate.
Therefore, according to the present invention, it is possible to provide a tablet counting inspection apparatus with good efficiency, availability, and performance at low cost.

With regard to such a tablet counting inspection apparatus of the present invention, a specific form for carrying out this will be described with reference to Examples 1 and 2 below .
In these drawings, for simplification, etc., a support such as a frame, a fastener such as a bolt, a coupling such as a hinge, a drive source such as an electric motor, a transmission member such as a cam, a motor driver, etc. Detailed circuits in an electronic circuit such as an electric circuit and a controller are not shown in the figure, and those necessary and related to the explanation of the invention are mainly shown.

  A specific configuration of the tablet counting inspection apparatus according to the first embodiment of the present invention will be described with reference to the drawings. 1A and 1B show a mechanical structure of a tablet counting inspection apparatus, where FIG. 1A is a plan view and FIG. 1B is a front view. FIG. 2 shows the main structure of the transfer mechanism, and both (a) and (b) are perspective views. FIG. 3 is a perspective view showing the main structure of the spreading mechanism. FIG. 4 is a functional block diagram of the electronic circuit unit.

This tablet counting inspection device 30 (see FIG. 1) is for performing a counting audit on each of the wrappings 11 (packaging bodies) partitioned in the longitudinal direction of the wrapping paper 10 (see FIG. 1). 5 (a)), roughly divided, a transfer spread imaging mechanism for drawing the wrapping paper 10 and imaging the wrapping 11 (see FIGS. 1 to 3), automatic operation of the number of wrapping agents in addition to its operation control And an electronic circuit unit for confirmation (see FIGS. 1 and 4).
In the case shown (see FIG. 1), the transfer spread imaging mechanism is arranged along the wrapping paper transfer path in the housing, and the wrapping paper 10 is pulled in from the receiving guide 35 on the left side and the delivery guide on the right side. 36 is discharged.

The electronic circuit unit (see FIG. 1) employs a programmable arithmetic control device such as a microprocessor system, and the controller 32 as the main body unit is stored in the electrical unit 31 in the housing together with a power supply unit (not shown). An operation unit 34 such as an operation panel provided with switches and keys, a display unit 33 such as a liquid crystal panel, and the like are disposed in an easy-to-use place, for example, on the front surface of the upper stage of the housing.
Note that the packet 11 (see FIGS. 5A to 5C) is divided into front and rear (left and right in the figure) by an end 12 containing a perforation 13, and two sides of the both ends 12 and another side. And the other side is bent, and the tablet 14 is accommodated therein.

  First, the transfer spread imaging mechanism will be described in detail (refer to FIG. 1). The transfer front part 41 to 43, the print information reading parts 61 to 62, the spread processing parts 51 to 54, and the imaging parts 63 to 64. , And a rear end portion 44 to 46 of the transfer section and a marker 37, which face from the upstream side to the downstream side, facing the dividing paper transfer path extending horizontally from the receiving guide 35 to the sending guide 36 (FIG. 1). (From left to right) in that order. In addition, they are supported at a predetermined position by an appropriate support or frame plate (not shown).

  An imaging stage 65 is the place where the imaging units 63 to 64 face between the spread processing units 51 to 54 and the transfer unit rear stage units 44 to 46 in the wrapping paper transfer path. The imaging units 63 to 64 include an imaging device 63 such as a CCD camera and an illuminating device 64 such as a halogen lamp. The illuminating device 64 illuminates the imaging stage 65 and the package that has been transferred to the imaging stage 65. The packet 11 of the paper 10 is taken by the imaging device 63. The illustrated one is a reflection type, but may be a transmission type.

  The place where the printing information reading units 61 to 62 face between the transfer unit front-stage units 41 to 43 and the spread processing units 51 to 54 in the dividing paper transfer path is a reading stage. Also, on the back of the wrapping paper 10, information such as the number of agents is printed in OCR (optical character reading) characters of a default font for each wrapping 11 of the tablet 11 or in an empty wrapping 11 just before the wrapping. There are many. The print information reading units 61 to 62 include an OCR 61 (character reading device) corresponding to a predetermined font and an illumination device 62 such as a halogen lamp. The illumination device 62 illuminates the reading stage and is transferred there. The print information of the wrapper 11 of the wrapper 10 is read by the OCR 61.

  The front part 41 to 43 of the transfer unit (see FIGS. 1 and 2A) forms a transfer mechanism together with the rear part 44 to 46 of the transfer part. A first transfer mechanism 41 installed on the side), a roller 42 protruding from the first transfer mechanism 41 to the upper surface of the wrapping paper transfer path, and a roller 43 protruding from the first transfer mechanism 41 to the lower surface of the wrapping paper transfer path; So that the wrapping paper 10 is sandwiched between the roller pairs 42 and 43 by rotating the rollers 42 and 43 around the shaft center by the motor and drive mechanism of the first transfer mechanism 41, respectively. It has become. In order to enable the forward feeding of the wrapping paper 10 from the receiving guide 35 to the sending guide 36 and the reverse feeding back to the opposite direction, the first transfer mechanism 41 can rotate both of the roller pairs 42 and 43. Can be done in the direction. Each of the rollers 42 and 43 is made of a sponge or the like that is easily deformed so as not to be affected by the thickness change of the wrapping paper 10.

  The transfer stage rear stage parts 44 to 46 (see FIGS. 1 and 2B) also include a second transfer mechanism 44 installed on the side just behind the packing paper transfer path (the rear side in FIG. 1) and the packing from there. The roller 45 protrudes from the upper surface of the paper transfer path and the roller 46 protrudes from the lower surface, and the rollers 45 and 46 are rotated about the shaft center by the motor and drive mechanism of the second transfer mechanism 44, respectively. Thus, the wrapping paper 10 is transported by being sandwiched between the roller pairs 45 and 46. The roller pairs 45 and 46 are made of a soft sponge or the like and can perform forward feed and reverse feed by bi-directional shaft rotation, similar to the transfer unit front stage parts 41 to 43. 46 can also change the transport direction of the wrapping paper 10.

  Specifically, the roller pairs 45 and 46 are swung (bidirectionally rotated) around the vertical line on the wrapping paper transport path. That is, the roller pairs 45 and 46 move together like a propeller on a horizontal plane centering on a vertical imaginary line instead of a horizontal axis. Since it is desirable that the vertical line of the swing center is located at the center of the wrapping paper transfer path, in this example, all of the second transfer mechanism 44 or a portion of the second transfer mechanism 44 supporting the roller pairs 45 and 46 is a roller. It swings together with the pair 45, 46.

  The spread processing units 51 to 54 (see FIG. 1 and FIG. 3) are provided on the upper surface of the wrapper paper transfer path from the spread mechanism 51 installed immediately next to the wrapper paper transfer path (the rear side in FIG. 1). The projecting brushes 52 and 53 and the projecting brush 54 on the lower surface of the wrapping paper transfer path are provided, and the brush groups 52 to 54 are moved by the motor and driving mechanism of the spreading mechanism 51 to wrap the wrapping paper. A mechanical action is applied to the ten packets 11. The movement of the brush groups 52 to 54 is for quickly spreading the tablets 14 in the wrap 11. For example, the brush 52 is moved downward and then swept in the traveling direction, and the brush 53 is lowered. After that, it is designed to stir with a spiral motion.

  Next, the electronic circuit unit and the drive unit controlled by the electronic circuit unit will be described in detail (see FIG. 4). The controller 32 is composed of a microprocessor system or the like as described above. In addition to the operation unit 34 and the display unit 33 described above, the OCR 61 and the imaging device 63 are also connected by a signal cable or the like. The lighting and reading timing are controlled, and print information read from the wrapping paper 10 is input. The imaging device 63 and the illumination device 64 are also connected to the controller 32 by a signal cable or the like. The controller 32 controls the timing of illumination and imaging, and takes in the image data into the image memory. A marker 37 for writing a defective mark or the like on the wrapper 10 is also connected to the controller 32 and is under its control.

  Furthermore, the controller 32 includes a sensor input circuit 71 for inputting detection results of various sensors, such as the presence / absence information of the packet 11, and a first transfer motor 72 that is provided in the first transfer mechanism 41 and rotates the roller pairs 42 and 43. A control drive circuit, a control drive circuit of a spread motor 73 provided in the spread mechanism 51 for spreading the brush groups 52 to 54, and a second transfer motor provided in the second transfer mechanism 44 for rotating the roller pairs 45, 46 about an axis. A control drive circuit 74 and a control drive circuit for a direction adjusting motor 75 which is also provided in the second transfer mechanism 44 but swings the roller pairs 45 and 46 instead of rotating the shaft are attached.

  The controller 32 is provided with an image memory for temporarily storing the image data fetched from the image pickup device 63, and in order to perform the tablet counting inspection process using the peripheral circuit and the like as described above. The program is installed. That is, a transfer control routine for controlling the first transfer motor 72 and the second transfer motor 74 for transferring the wrapping paper 10 and a spread control for controlling the spread motor 73 for spreading the tablets 14 in the package 11. A control routine, a perforation extraction routine for extracting a partial image of the perforation 13 from the image data in the image memory, a tilt detection routine for calculating the inclination of the perforation 13 from the extraction result, and a package from the image data in the image memory A drug image extraction routine for extracting a partial image of the tablet 14, a counting routine for counting the number of tablets 14 in the package from the extraction result, a determination as to whether or not the count value matches the prescription value, etc. A determination routine and a display routine for performing monitor display of the imaging result, confirmation display of the determination result, and the like are installed. Characteristic processing among these routines will be described in detail in the following operation description.

  The use mode and operation of the tablet counting inspection apparatus of the first embodiment will be described with reference to the drawings. FIG. 1 is a plan view and a front view of the tablet counting inspection apparatus 30 with a supply unit 21 and a storage basket 23 for the wrapping paper 10 attached thereto. FIG. 5 is a plan view for explaining the operation, in which (a) is a wrapping paper in which a number of wrappings are arranged in a row, (b) is a wrapping in which tablets before spreading are enclosed, and (c) is a tablet after spreading. (D) is an example of imaging data, (e) is an example of agent image area data, (f) is an example of perforation area data, (g) is a packet in which direction adjustment is performed by half, (h) Indicates a package in which twist is eliminated.

  The wrapping paper 10 to be counted and audited (see FIG. 5A) is a series of wrappings 11, each wrapping 11 being separated by an end 12 and containing one or more tablets 14. A typical size of the packet 11 (see FIGS. 5B and 5C) is about 70 mm in width (up and down in the figure) and about 80 mm in length (left and right in the figure). The width of the end portion 12 (between the packets 11 adjacent to the left and right in the drawing) is about 10 mm, and a perforated line 13 is formed there. A typical example of the tablet 14 is a ball having a diameter of several millimeters, a capsule longer than that, and the like, which are often mixed.

  Since this tablet counting inspection device 30 is a stand-alone type (see FIG. 1), in order to supply the packaging paper 10 to the tablet counting inspection device 30, a supply unit 21 is attached to the receiving guide 35 side, Wrap the wrapped wrapping paper 10. The storage basket 23 that receives the wrapping paper 10 discharged from the tablet counting inspection device 30 is placed along the delivery guide 36 side. When the leading end of the wrapping paper 10 is set in the receiving guide 35 and the transfer mechanisms 41 to 46, the wrapping paper 10 is intermittently transferred in units of 11 wraps by the transfer mechanisms 41 to 46 under the control of the transfer control routine. The

  At each intermittent transfer, the print information of the packet 11 coming there is read by the OCR 61 and the illumination device 62 at the upstream reading stage, and the spread control routine control is performed for the packet 11 coming there at the intermediate spread stage. Spreading processing (preprocessing) is performed by the lower processing units 51 to 54, and imaging is performed on the packet 11 by the imaging device 63 and the illumination device 64 in the downstream imaging stage 65. Therefore, even if the tablets 14 are overlapped in the wrap 11 before the spread process (see FIG. 5B), the tablets 14 are scattered in the wrap 11 after the spread process so that there is no overlap (FIG. 5C). reference).

  The image data taken by the imaging device 63 (see FIG. 5D) is displayed on the monitor 33 and stored in the image memory of the controller 32, and the image processing of the perforation extraction routine and the agent image extraction routine is performed. To be served. By the processing of the drug image extraction routine, a drug image area 81 that reliably contains the drug image that is the image of the tablet 14 is cut out (see FIG. 5E), and noise removal processing, drug image division processing, and the like are performed on it. . Cutting out the agent image area 81 is performed on a partial area of the fixed range unless the twist of the wrapping paper 10, that is, the inclination θ of the wrapping 11 from the traveling direction is not so large (see FIG. 5B). . From the agent image area 81, the number of agent image chunks is counted by a counting routine, and this is used as the agent number in the packet 11.

  The number of agents is compared with a prescription value known by reading of the OCR 61 by a determination routine, and if it matches, it is determined to be appropriate, and if it does not match, it is determined to be inappropriate. The determination result is displayed on the display unit 33 by a display routine. Further, according to the determination result, if it is appropriate, the normal delivery of the wrapping paper 10 is performed by the transfer control routine, whereas if inappropriate, the wrapping paper 10 is reversely fed by the transfer control routine. And retry from the spread process. If it is inappropriate even after retrying, the audit result to that effect is displayed on the display unit 33, and a defective mark or the like is written on the corresponding packet 11 with the marker 37.

  In parallel with the tablet counting process, twist detection and twist elimination of the wrapping paper are also performed. That is, the perforation region 82 including the image of the perforation 13 is cut out from the image data of the image memory by the process of the perforation extraction routine (see FIG. 5F), and noise removal processing and the like are performed on it. The perforated region 82 is cut out for a partial region of the fixed range unless the twist of the wrapping paper 10, that is, the inclination θ from the traveling direction of the wrap 11 is not so large. An approximate straight line of the perforation is obtained from the perforation region 82 by a known method such as a least square method, and the inclination component of the approximate straight line is set to the inclination Θ of the perforation.

  Since this inclination Θ corresponds well to the twist of the wrapping paper 10 and is almost the same as the inclination θ, it is handed over to the transfer control routine, and the direction adjusting motor 75 operates to eliminate the inclination Θ. The amount of direction adjustment may theoretically be the inclination Θ as it is, but here, the stability is emphasized and only half of the inclination Θ is suppressed by feeding a single package, that is, Θ / 2. Twist is halved to θ / 2 (see FIG. 5G). If no new twisting factor is added, the twist of the packet 11 is quickly eliminated (see FIG. 5H). Actually, twisting factors are added one after another, but they are not stacked and become large, and the twisting of the wrapping paper 10 is within a small range that does not hinder high-speed transfer for a long time.

A specific configuration of the tablet counting inspection apparatus according to the second embodiment of the present invention will be described with reference to the drawings. 6A is a front view showing the mechanical structure of the tablet counting inspection device, and FIG. 6B is a functional block diagram of the electronic circuit unit.
This tablet counting inspection apparatus is different from that of the first embodiment described above in that a tablet packaging machine 24 is introduced instead of the supply unit 21 and a main controller 90 is added.

  The main controller 90 is composed of a personal computer or the like, and is provided with an operation unit 91 such as a keyboard and a display unit 92 such as a display, and is placed on the desk beside the tablet counting inspection device 30 so as to be easy to use. . The controller 32 is a local controller, and the agent image extraction routine, the counting routine, the determination routine, the display routine, the print information reading units 61 to 62, the interfaces of the imaging units 63 to 64, and the control drive circuit of the marker 37 are supplied from the controller 32. The main controller 90 is relocated.

Both controllers 90 and 32 are connected so as to be able to communicate with each other by a signal cable or the like for transmitting an operation instruction or an operation result. The main controller 90 is also connected to the controller of the tablet packaging machine 24 through a signal cable or the like.
Then, under the integrated control of the main controller 90, the wrapping paper 10 in which the tablets 14 are packaged by the tablet packaging machine 24 is immediately sent to the tablet counting inspection device 30 and subjected to automatic counting inspection.

[Others]

For example, one that causes vibration to be applied to the packet 11 with a vibration member, one that presses both ends of the packet 11 with a clamp member to cause the packet 11 to expand and contract, or one that temporarily inflates the packet 11 using vacuum Or a combination of them as appropriate.
In the second embodiment, the main controller 90 (counting inspection unit) and the tablet counting inspection device 30 (transfer spreading imaging mechanism unit) are one-to-one. However, if the processing capacity of the main controller 90 is sufficient, one main controller 90 A plurality of tablet counting inspection devices 30 may be installed in 90.
