Description

[Technical Field]

[0001] The present invention relates to a packaging paper line drawing device that draws lines on packaging paper, and a medicine packaging machine that divides medicines into individual packets and packages them. [Background technology]

[0002] A known packaging device encloses powder or solid packaged items in long wrapping paper divided into predetermined lengths and seals the wrapping paper with heat after the packaged items are enclosed (see, for example, Patent Document 1). Also known is a configuration in which the above-mentioned packaging device is added with a tablet discharge device or powder medicine dispensing device that discharges predetermined amounts of medicine as packaged items, thereby operating as a medicine packaging machine (see, for example, Patent Documents 2, 3, and 4).

[0003] Known medication packaging machines include one equipped with a printing mechanism along the path of the packaging paper in which the medication is packaged, which prints patient information, medication dosage information, and other information onto the packaging paper. One type of dosage information is information about when medication should be taken (morning, noon, evening, or night), and the printing mechanism prints the dosage information in text. Other known machines include a packaging paper marking device that uses colored lines to indicate the dosage times in addition to or instead of text. Furthermore, a tablet inspection device is known that inspects the number and shape of tablets, judges whether they are good or bad, and activates a marking means based on the judgment results, making it possible to quickly determine whether they are good or bad (see, for example, Patent Document 5). In this technology, five pens of five colors are individually displaced by five solenoids that act as actuators, and colored lines are applied to packaging bags in different colors.

[0004] However, in the above-mentioned configuration, since N writing implements are displaced by N actuators, there is a problem in that the device configuration becomes complicated and the device becomes large. In particular, the packaging paper line drawing device used in the above-mentioned medicine packaging machine is located downstream of the packaging paper transport path within the packaging device of the medicine packaging machine, and must fit into a small space because it is installed between the various mechanisms that make up the packaging device. Therefore, a packaging paper line drawing device has been proposed in which a writing instrument is displaced to an advance / retract position by one actuator, and the writing instrument displaced to the advance / retract position is advanced / retracted by another actuator (see, for example, Patent Document 6).

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-051305 [Patent Document 2] Japanese Patent Application Laid-Open No. 2014-188101 [Patent Document 3] Japanese Patent Application Laid-Open No. 2004-168427 [Patent Document 4] Patent No. 3524680 [Patent Document 5] Japanese Patent Application Laid-Open No. 2000-135268 [Patent Document 6] Patent No. 6555689 Summary of the Invention [Problem to be solved by the invention]

[0006] Recently, there has been a push to make medicine packaging machines more compact, particularly in the components that make up the device. While the technology disclosed in Patent Document 6 simplifies the configuration, including the writing implement and actuator, there is room for improvement, particularly in terms of miniaturizing the packaging paper line drawing device itself in the height direction (thickness direction). The present invention aims to solve the above-mentioned problems and provide a packaging paper line drawing device that has a simple configuration and can be made compact in height, and a medicine packaging machine equipped with the same. [Means for solving the problem]

[0007] The invention described in claim 1 is characterized by comprising a unit body, a holding member that holds multiple writing instruments flush with each other, a first moving member that moves one of the writing instruments held by the holding member in the direction in which the writing instruments are arranged to a drawing position where the writing instrument will be located when drawing a line on the packaging paper, and a second moving member that moves the writing instrument that occupies the drawing position to a drawing position where it can come into contact with the packaging paper. [Effects of the Invention]

[0008] According to the present invention, the packaging paper line drawing device can be made smaller, particularly in the height direction, and the medicine packaging machine equipped with the packaging paper line drawing device can be made smaller. [Brief explanation of the drawings]

[0010] Figure 1 shows a schematic front view of the internal structure of a medicine packaging machine according to one embodiment of the present invention, and Figure 2 shows a schematic perspective view of the same. In each figure, when the medicine packaging machine is viewed from the front where an operator stands, the direction from left to right is the X direction, the direction from the front to the back is the Y direction, and the direction from bottom to top is the Z direction.

[0011] The medicine packaging machine 1 is provided with a tablet processing unit 5 at the top of the device main body 2, which includes a manual distribution unit 3 located on the top surface of the device main body 2 and through which an operator manually adds medicines such as tablets, and a transport unit 4 that transports the medicines added to the manual distribution unit 3 to a packaging device 8 located below, which will be described later. The medicine packaging machine 1 also has a powder medicine processing unit 7 below the tablet processing unit 5, which includes a distribution disk 6 through which an operator adds a weighed amount of medicine such as powder medicine and distributes it to the specified amount specified in the prescription. The medicine packaging machine 1 also has a packaging device 8 below the device main body 2, which individually packages medicines, including tablets and powder medicines, sent from the tablet processing unit 5 and the powder medicine processing unit 7 in packaging paper. The medicine packaging machine 1 functions as a medicine packaging machine that packages a mixture of tablets and powdered medicine, a powdered medicine packaging machine that packages powdered medicine, and a tablet packaging machine that packages tablets.

[0012] In this embodiment, the drug packaging machine 1 is shown as being configured to integrally include a tablet processing unit 5, a powdered medicine processing unit 7, and a packaging device 8, but it may also be configured to have a tablet cassette that stores tablets and sends them one by one to the tablet drop path, or a powdered medicine cassette and storage shelf for storing powdered medicine. The medicine dispensing and packaging machine 1 shown in this embodiment is provided with a control unit 9 on top of the device main body 2, in which applications and the like for controlling the operation of each component of the device are installed.

[0013] As shown in Figure 2, the tablet processing unit 5 is located at the top of the device main body 2 and has a manual distribution unit 3 covered by an openable and closable lid, and a conveying unit 4 located below the manual distribution unit 3 and conveying tablets fed into the manual distribution unit 3 downward. The manual distribution unit 3 has multiple divided compartments 3a, and tablets are manually distributed into each compartment 3a. The conveying unit 4 is movable left and right in FIG. 1 and has multiple compartments 4a corresponding to each compartment 3a. When the conveying unit 4 assumes its initial position where each compartment 4a is located below the corresponding compartment 3a, the bottom of each compartment 3a is released and the tablets are transported to each compartment 4a. Thereafter, as the conveying unit 4 moves from its initial position in the +X direction, the tablets transported into each compartment 4a are released from the bottom of the compartment 4a each time the conveying unit 4 moves one square of the compartment 4a and the compartment 4a reaches the tablet hopper 10 located below. The tablet hopper 10 is located at the rear of the device, in the +Y direction of the powdered medicine processing unit 7.

[0014] As shown in Fig. 3, the powdered medicine processing unit 7 has a circular distribution disk 6, two troughs 11 arranged facing each other on the front side of the distribution disk 6 below an input hopper 15 (described later) for transporting the powdered medicine input into the input hopper 15 toward the distribution disk 6, and a feeder drive unit 12 arranged adjacent to the input hopper 15 and the trough 11 for vibrating the input hopper 15 and the trough 11. As shown in Fig. 1, an annular groove 6a is formed on the upper surface of the distribution disk 6 to uniformly distribute the powdered medicine.

[0015] The powdered medicine processing section 7 has a cutting and cleaning device 13 downstream of the trough 11 in the rotation direction of the distribution disk 6. In this embodiment, the rotation direction of the distribution disk 6 is described as counterclockwise, but the rotation direction of the distribution disk 6 may also be clockwise. In this embodiment, the input hopper 15 and the trough 11 form a pair and are arranged so that the two pairs face each other, and the cutting and cleaning device 13 is arranged on the most downstream side of the pair of input hopper 15 and trough 11. The cutting and cleaning device 13 scrapes out the powdered medicine scattered on the distribution disk 6 toward the tablet confluence section 14 and cleans the annular groove 6a after the powdered medicine has been scraped out. In Figure 2, the upper part of the device main body 2, including the manual distribution section 3, is configured to be openable upward using the +Y direction end as a fulcrum, and each part of the powdered medicine processing section 7 can be cleaned with the upper part of the device main body 2 open.

[0016] As shown in Figure 4, the feeding hopper 15 is detachably supported by a hopper holding frame 16 provided on the feeder drive unit 12. The feeding hopper 15 has a funnel shape that narrows downward, and the powdered medicine inside falls into the trough 11 from an opening 20 (see Figure 5) provided at the lowest part. The outer surface of the feeding hopper 15 is provided with triangular protrusions 15a that protrude outward, at two locations on each side, for a total of four locations. These protrusions 15a engage with the hopper holding frame 16, thereby supporting the feeding hopper 15 on the hopper holding frame 16.

[0017] As shown in Figures 4 and 5, trough 11 is supported by vibrating unit 17 extending from feeder drive unit 12 and is arranged to slope gently downward from the rear end to the front end. As shown in Figures 4 and 6, trough 11 has powdered medicine dispensing unit 18 at its front end, which is formed to move the powdered medicine toward the center so that the powdered medicine falls into the center of annular groove 6a, and sloped unit 19, which is formed to taper toward powdered medicine dispensing unit 18 and have an increasing slope. The vibrating unit 17 is a vibrating plate that is vibrated by the feeder driving unit 12, and vibrates finely based on a signal from the feeder driving unit 12, causing the trough 11 placed above to vibrate finely. By applying vibrations from the vibrating unit 17, the powdered medicine placed on the trough 11 is transported in the X direction.

[0018] Hopper holding frame 16, which is made of a pipe-shaped member, is a rectangular frame body that is open at the tip end on the X-direction side of input hopper 15, and supports each of protrusions 15a from below. As shown in Fig. 5, hopper holding frame 16 is rotatably supported at its rear end by a support shaft 21, and input hopper 15 can be moved up and down around support shaft 21 as hopper holding frame 16 rotates. As shown in Figure 5, by rotating the feeding hopper 15 upward, the gap between the opening 20 and the trough 11 increases, and the amount of powdered medicine that falls from the feeding hopper 15 increases. The powdered medicine that falls from the feeding hopper 15 onto the trough 11 is transported along the bottom surface of the trough 11, which is vibrated by the vibrating section 17, and falls into the annular groove 6a of the distribution disk 6 via the inclined section 19 and the powdered medicine cutting section 18.

[0019] The powdered medicine dispensing section 18 is a recess formed in the widthwise center of the trough 11. As shown in FIG. 6, both sides of the dispensing section 18 narrow in the direction of transport so that the powdered medicine gathers toward the end of the dispensing section. The powdered medicine dispensing section 18 is positioned in a recessed portion in the annular center of the distribution disk 6, most preferably directly above the center of the annular groove 6a. The powdered medicine transported through the trough 11 falls into the center of the annular groove 6a of the distribution disk 6. The amount of powdered medicine falling from the powdered medicine dispensing section 18 can be adjusted by controlling the vibration of the vibration section 17. Typically, as shown in FIG. 7, the amount of powdered medicine falling from the powdered medicine dispensing section 18 is adjusted so that a predetermined amount falls at a time. With this configuration, by rotating the distribution disk 6 at a predetermined rotational speed for one or more revolutions, a pile of powdered medicine is uniformly distributed on the annular groove 6a.

[0020] Once the powdered medicine has been evenly dispersed on the annular groove 6a, the control unit 9 rotates the distribution disk 6 at a predetermined angular velocity. Specifically, if one rotation is 360 degrees, which is one prescription, and the disk is to be divided into ten packets, the appropriate amount for one packet is collected near the cutting and cleaning device 13, and then the cutting and cleaning device 13 deposits the powdered medicine into the hopper 22 shown in FIG. 1 by rotating the distribution disk 6 at 36 degrees. 3, the cutting and cleaning device 13 has at one end a circular disk 23 whose periphery abuts against the annular groove 6a, and a scraper 24 rotatably attached to the disk 23 for scooping up and scraping out the powdered medicine on the annular groove 6a blocked by the disk 23. At the other end of the cutting and cleaning device 13 is provided a cleaner unit 25 for cleaning the distribution disk 6 after packaging of one prescription has been completed.

[0021] 8 shows a schematic side view of the internal configuration of a medicine packaging machine according to one embodiment of the present invention. In the figure, tablet confluence section 14 guides tablets dropped from tablet processing section 5 via conveying section 4 and powdered medicine dispensed into individual packets in powdered medicine processing section 7 to hopper 22 via separate paths. The tablet confluence section 14 has a push-pull member 26 that is provided at the bottom of the tablet hopper 10 and collects tablets that have fallen through the tablet hopper 10, and a moving member 27 that moves the push-pull member 26 from the position shown in Figure 8 toward the front of the device in the -Y direction.

[0022] In its initial standby state, which is its initial state, the tablet junction 14 is in the state shown in FIG. 8, in which the push-pull member 26 is located below the tablet hopper 10, and when tablets are discharged from the tablet processing unit 5, the push-pull member 26 receives the discharged tablets. When the tablet junction 14 discharges the tablets in the push-pull member 26, it operates the moving member 27 to move the push-pull member 26 to the left in FIG. 8, causing the tablets in the push-pull member 26 to drop into a receiving hopper 28 provided above the hopper 22. The receiving hopper 28 has a bottom plate that can be opened and closed freely, and when this bottom plate is opened, the medicine inside drops into the hopper 22.

[0023] The medicines such as tablets and / or powder medicine that have fallen into the hopper 22 are packaged in packaging paper 29 by the packaging device 8 shown in Figures 1, 9 and 10. The arrows in Figures 9 and 10 indicate the front of the device. Packaging device 8 includes, in order along the conveyance path of packing paper 29, packing paper feed unit 30 that holds packing paper roll 29A and applies appropriate tension to packing paper 29, feeding packing paper 29 from the leading edge, marker unit 31 as a packing paper line drawing device that draws a line on packing paper 29, printer 32 that prints on the packing paper, sealing unit 33 that has heater 38 that heats packing paper 29 and seals packing paper 29, hopper 22 that moves up and down to insert and remove the leading edge into packing paper 29 folded in half, conveyor roller 34 that conveys the packing paper, and cutter 35 that cuts packing paper 29. Note that hopper 22 is not shown in Figure 9.

[0024] After tablets, powdered medicines, etc. are sealed in compartments of a specified length, one end of the packaging paper 29 is heat-fused and the paper is discharged from the downstream outlet 36 to the outside of the packaging device at the length set in the prescription information. Packaging paper 29 is folded in half with one side open and is then drawn out from packaging paper feeder 30. Packaging paper 29 drawn out from packaging paper feeder 30 is lined by marker unit 31 if necessary, printed by printer 32, and then moves below hopper 22, where the front end in the conveying direction is sealed by sealing unit 33, medicines are poured into the paper by hopper 22, the top end is sealed, cut by cutter 35, or perforated, and then the paper is discharged. Marker unit 31 will be described later.

[0025] Figure 11 shows sealing unit 33 with pressing member 37 removed, and Figure 12 shows sealing unit 33 with pressing member 37 attached. Sealing unit 33 is provided with pressing member 37, which is attached so as to be able to move toward and away from the packaging device main body, a heater 38 that heats packaging paper 29 and simultaneously performs conventional vertical and horizontal sealing on packaging paper 29, and a perforation blade receiver 40 that receives perforation blade 39, and pressing member 37 is also provided with perforation blade 39. With this configuration, when heater 38 generates heat, pressing member 37 comes into contact with the packaging device main body via packaging paper 29, thereby sealing packaging paper 29 with heater 38 and forming perforations in packaging paper 29. A conveyance roller 34 and a cutter 35 are provided downstream of sealing unit 33 in the direction in which packaging paper is conveyed. Packaging paper 29 discharged from discharge port 36 is stored in packaging paper container 41 which is detachably provided on device main body 2, as shown in FIG.

[0026] 8, a suction device 42 for suctioning air is disposed in the middle of the device body 2. The suction device 42 is provided with a plurality of suction ports 42a that open to the outside and fins disposed inside the device, and air is sucked in from various parts of the device on the front side and exhausted from the rear side of the device. A cleaning device and a cutting cleaning device 13 for cleaning the outside and inside of the device are connected to the suction device 42.

[0027] Next, a description will be given of the marker unit 31, which is used in one embodiment of the present invention and is a characteristic part of the present invention. As shown in Fig. 13, the marker unit 31 has a unit main body 43 and a pen holder 44 as a holding member. A movable base 45 that detachably holds a pen holder 44 is provided on the unit main body 43 so as to be movable in the direction indicated by arrow A in Fig. 13. As shown in Fig. 14, the movable base 45, which is a first movable member, is provided with a linear bushing 47 that is slidably supported on a linear guide 46 provided on the unit main body 43. The unit main body 43 also has a stepping motor 48 as a first drive means that drives the movable base 45, as shown in Fig. 14, a gear 49 to which the rotational drive force of the stepping motor 48 is transmitted, as shown in Fig. 15, and a rack 50 that is connected to the movable base 45 and meshes with the gear 49, as shown in Fig. 15.

[0028] With the above-described configuration, when the stepping motor 48 rotates forward, the gear 49 rotates forward, and the rack 50 meshing with the gear 49 and the movable base 45 move to the right in Fig. 13. When the stepping motor 48 rotates reversely, the gear 49 rotates reversely, and the movable base 45 moves to the left in Fig. 13. The pen holder 44 is configured to be detachable from the movable base 45 by engaging an engaged portion provided on the pen holder 44 with an engaging portion provided on the movable base 45. The engaged portion and the engaging portion can be configured using conventionally known structures such as a pin and an associated hook, or a recess and a retractable protrusion that fits into the recess. A rear cover 51 shown in FIG. 14 and a front cover 52 shown in FIG. 15 are attached to the unit body 43 by a known method such as screw fastening.

[0029] 13, in this embodiment, six color pens 53, which are writing implements of different colors, are held in the pen holder 44. Each color pen 53 is held flush with the upper surface of the pen holder 44, and is held so that the axial direction of each color pen 53 is perpendicular to the direction of movement of the pen holder 44 associated with the movement of the movable base 45, i.e., in the arrangement direction of each color pen 53. As shown in Figure 16, color pen 53 is detachably supported by holder member 54. Holder member 54 has hook portion 54a with which tip portion 53a of color pen 53 engages, and elastically deformable retaining portion 54b that is gripped when attaching or detaching and into which main body portion 53b of color pen 53, which is formed to a uniform thickness, fits. Color pen 53 is supported by holder member 54 as shown in Figure 16(a) by engaging tip portion 53a with hook portion 54a at an angle of about 30 degrees as shown in Figure 16(b), and then fitting main body portion 53b into retaining portion 54b by laying it down.

[0030] The holder members 54 are held by the pen holder 44 so as to be able to move freely in the direction indicated by arrow B in Fig. 13, and the multiple holder members 54 are arranged closely spaced in the pen holder 44, with adjacent holder members 54 being in contact with or close to each other as shown in Fig. 17(b). Rail members (not shown) that support the holder members 54 so as to be able to move freely in the direction indicated by arrow B are provided on the upper surface of the pen holder 44, and the holder members 54 are supported on these rail members so as to be able to slide and be detachable. As shown in Fig. 16, a first protrusion 54c and a second protrusion 54d are formed on the bottom surface of the holder member 54. As shown in Fig. 17(a), the first protrusion 54c and the second protrusion 54d are fitted into holes 44a and 44b, respectively, formed in the bottom surface of the pen holder 44, and are disposed so as to protrude from the holes 44a and 44b. The holder member 54 is biased by a compression spring 58, which is a biasing member, in a direction in which the pen tip of the color pen 53 moves backward (in a direction in which the pen tip moves rightward in Fig. 13), and is normally positioned in an initial position in which the protrusions 54c and 54d abut against the right ends of the holes 44a and 44b, respectively, as shown in Fig. 18(a).

[0031] As shown in FIG. 17(a), the unit main body 43 is provided with a lever member 55 as a second moving member that moves the holder member 54. The lever member 55, which has a protrusion 55a, is rotatably supported by a support shaft 56, and selectively occupies an operating position shown in FIG. 17(a) or an initial position shown in FIG. 18(a). A tension spring 55b is attached to the lever member 55, and applies a biasing force in a direction that causes the lever member 55 to abut against the first protrusion 54c. The biasing force of the tension spring 55b is set to be greater than the biasing force of the compression spring 58. 14, the unit body 43 is provided with a motor 57 as a second driving means for driving the lever member 55. The lever member 55 is driven by the operation of the motor 57, and one holder member 54 positioned at a predetermined position in the unit body 43 moves in the direction of arrow B in FIG. 13 as the moving base 45 moves.

[0032] When the movable base 45 occupies the initial position, which is the leftmost position in FIG. 13, the marker unit 31 is positioned such that the protrusions 54c, 54d of the holder member 54 located at the rightmost side of the pen holder 44 (the most downstream side in the direction of movement of the movable base 45) can engage with the lever member 55, as shown in FIG. 19(a) . From this state, the stepping motor 48 operates for each different color of color pen 53 to be used based on a command from the control unit 9, and the protrusions 54c, 54d of the selected color pen 53 are positioned such that they can engage with the lever member 55, as shown in FIG. 20(a) , until the movable base 45 occupies the rightmost position in FIG. 13. The above-mentioned positions where the protrusions 54c, 54d of each holder member 54 can engage with the lever member 55 are the drawing positions in the present invention.

[0033] When the holder member 54 holding the designated color pen 53 is positioned in the drawing position, the motor 57 is then actuated to displace the lever member 55 from the initial position to the actuated position. Accompanying this displacement, the first protrusion 54c is moved to the left in FIG. 17(a) (toward the front of the marker unit 31) by the lever member 55, as shown in FIG. 17(a). At this time, the motor 57 is not transmitting its driving force to the lever member 55, and the lever 55 moves the first protrusion 54c to the left by the biasing force of the tension spring 55b against the biasing force of the compression spring 58. When first protrusion 54c and holder member 54 move leftward, the tip of designated color pen 53 comes into contact with packing paper 29 as shown in Figure 17(b), and when packing paper 29 is transported by the transport operation of packaging device 8, a line in the designated color is drawn on packing paper 29. At this time, the contact pressure of color pen 53 against packing paper 29 is set to a predetermined contact pressure by tension spring 55b. The position where the tip of color pen 53 comes into contact with packing paper 29 as described above is the line drawing position in the present invention.

[0034] According to the above-described configuration, the marker unit 31 of the present invention has a pen holder 44 movably held in the unit body 43 that holds multiple color pens 53 flush, allowing the marker unit 31 to be made smaller, particularly in the height direction, and the drug packaging machine 1 equipped with the marker unit 31 to be made smaller. Furthermore, since the color pen 53 can be moved to the drawing position and the line drawing position using two moving members, the configuration can be simplified. Furthermore, since the plurality of holder members 54 for supporting the respective color pens 53 are movably held in the pen holder 44, the designated color pen can be moved to the line drawing position with a simple structure.

[0035] Furthermore, since multiple holder members 54 are arranged closely spaced on the pen holder 44, the distance between each holder member 54 can be shortened, and the size of each holder member 54 in the arrangement direction (the direction indicated by arrow A in Figure 13) can be reduced, thereby making the device more compact. Furthermore, since the moving base 45 that moves the color pen 53 to the drawing position and the lever member 55 that moves it to the line drawing position are separate, the configuration of the moving member and the device configuration of the marker unit 31 can be simplified. Furthermore, since the marker unit 31 has a stepping motor 48 that drives the movable base 45 and a motor 57 that drives the lever member 55, the marker unit 31 can be constructed with only two motors, which simplifies the device and reduces costs.

[0036] The aspects of the present invention are as follows, for example.
