At the rear end of the shelf 2, there is provided a harness 28 for energizing the drum motors of the tablet cases 3 and transmitting the output from the agent detection sensor.
[0020]
When the shelves 2 are stored in the case storage section 8, the passages 9 of the upper and lower shelves 2 correspond to each other, whereby a series of chutes 32 communicated vertically. Is composed. Therefore, in the embodiment, four rows of right and left chutes 32...
[0021]
On the other hand, the packing machine 13 (filling device) is housed in the lower portion of the lower structure 7B of the main body 7 as described above. Although the structure of the packaging machine 13 will be described later in detail, as shown in FIG. 3, the packaging machine 13 is detachably screwed to drawer rails 47 attached to the right and left bottom surfaces in the lower structure 7B. As a result, the packaging machine 13 can be pulled out from the lower structure 7B forward with the lower panels 4, 4 opened, and can be attached to and detached from the draw-out rails 47 in the pulled-out state. I have. Reference numeral 48 denotes a harness for the packaging machine, which is detachably connected between the packaging machine 13 and the lower structure 7B by a connector, and has a length that allows the withdrawal amount of the packaging machine 13 to be sufficiently allowed.
[0022]
Two opening / closing plates 53, 53 are juxtaposed on the left and right at the upper part in the lower structure 7B. Each of the open / close plates 53, 53 corresponds to the lower part of the above-mentioned chutes 32,..., And the open / close plate 53 on the right side opens and closes on the left side toward the right end and the chutes 32, 32 on the right side. The plate 53 corresponds to the chutes 32, 32 on the left end and the right side thereof. Then, it plays a role of temporarily receiving the medicine that falls from each of the chutes 32 to the hopper 54 described later.
[0023]
The hopper 54 is provided in the lower structure 7B below each of the open / close plates 53. The hopper 54 has a rectangular funnel shape having a wide open upper surface and narrowing toward the lower end. The hopper 54 receives the medicine dropped from each of the chutes 32. It is discharged from the opening 54A.
[0024]
The upper left and right sides of the hopper 54 are detachably screwed to drawer rails 56, 56 attached to the upper left and right in the lower structure 7B, and the respective open / close plates 53, 53 are also located above the drawer rails 56, 56. And are detachably screwed to the draw-out rails 56, 56. As a result, the hopper 54 and the opening / closing plates 53, 53 can be simultaneously pulled out forward from the inside of the lower structure 7B with the lower panels 4, 4 opened, and further with the drawn rails 56, 56 in the pulled-out state. It is removable. Although not shown, a detachable harness for the opening / closing plate 53 is also provided, and this harness also has a length that allows a sufficient amount of pull-out of the opening / closing plate 53.
[0025]
With such a structure, when performing maintenance such as replacement of the tablet case 3, cleaning of the chutes 32... Constituted by the passages 9, cleaning of the hopper 54, and replacement of parts of the packaging machine 13, These can be pulled out from the upper structure 7A or the lower structure 7B of the main body 7 and can be attached or detached.
[0026]
As a result, maintenance workability of the medicine supply device 1 is significantly improved, and smooth medicine filling can be realized. In particular, since a plurality of tablet cases 3 are simultaneously drawn out of the upper structure 7A together with the shelf 2 and the storage containers thereof are detachably attached, the workability of replacing the storage containers of the tablet case 3 is further improved.
[0027]
Further, since the opening / closing plates 53 are also detachably attached to the lower structure 7B, the maintenance workability of the opening / closing plates 53, 53 for temporarily receiving the medicine falling to the hopper 54 can be improved. Become like In particular, since the opening / closing plates 53 and 53 and the hopper 54 are attached so as to be able to be pulled out from the lower structure 7B at the same time, the operability when maintaining the opening / closing plate 53 and the hopper 54 can be further improved.
[0028]
Further, an additional medicine feeder (UTC) 57 is attached to the center of the upper part in the lower structure 7B between the opening and closing plates 53, 53. In this case, the additional medicine feeder 57 is independently pulled out forward without being covered by the lower panels 4 and is detachably attached (FIG. 1). The additional medicine feeder 57 is a feeder for arbitrarily supplying an additional medicine. The feeder 57 communicates with the hopper 54.
[0029]
Next, the configuration of the packaging machine 13 will be described with reference to FIG. Reference numeral 71 denotes a roll around which heat-weldable wrapping paper 72 (constituting a container) is wound, 73 denotes a printer, 74 denotes a nozzle attached to the lower end opening 54A of the hopper 54, and 76 denotes a heat seal head made of silicon rubber. , 77 are rollers for transporting the wrapping paper 72 pulled out from the roll 71, 79 is a cutter for cutting the wrapping paper 72, 81 is an outlet provided on the lower panel 4 for separating and cutting the wrapping paper 72. The conveyor is a conveyor that transports the wrapping paper 72 along the transport path. Reference numeral 83 denotes a motor for operating the heat seal head 76, reference numeral 78 denotes a motor for driving the rollers 77, and reference numeral 84 denotes a motor for the conveyor 81.
[0030]
The wrapping paper 72 wound around the roll 71 has an open top surface and is folded (semi-folded) at the lower end to have a substantially V-shaped cross section. The wrapping paper 72 is once pulled out obliquely rightward and upward from the roll 71 by a roller 77 or the like. After being drawn obliquely downward and to the right, the printer 73 prints on its surface as described later. Next, the medicine released from the nozzle 74 is put into the wrapping paper 72, and the wrapping paper 72 is partitioned into packages by heat welding by the heat seal head 76. The divided and packaged paper 72 is then cut by a cutter 79 and conveyed by a conveyor 81 to an upper left outlet 82.
[0031]
In this case, the wrapping paper 72 is wound around a cylindrical shaft tube 70 (made of synthetic resin) to form a roll 71 as shown in FIG. It is detachably attached to a wrapping paper delivery mechanism 102 provided below the mounting plate 101 inclined at an angle of 20 degrees. As shown in FIG. 6, the wrapping paper delivery mechanism 102 includes a disc-shaped base plate 103, an engagement shaft 104 protruding from the center of the base plate 103, and a guide provided corresponding to the lower side of the base plate 103. It is composed of a plate 106 and a brake mechanism (not shown) that contacts the lower side of the base plate 103.
[0032]
The engaging shaft 104 is made of metal or synthetic resin, and has a plurality of engaging ridges 107 formed on the side surface thereof as shown in FIG. Each of the engaging ridges 107... Extends in the axial direction of the engaging shaft 104 (in FIG. 4, the engaging shaft 104 projects obliquely to the upper right from the base plate 103, and in FIG. 5 to project obliquely to the upper left). ) Is formed so as to intersect at a predetermined angle with respect to the direction of rotation of the engagement shaft 104 and the base plate 103 (see FIG. 6 (indicated by an arrow in FIG. 6). The tip of the engagement shaft 104 has a predetermined tapered shape so as to be tapered, and a tapered portion 108 is formed there.
[0033]
On the other hand, the inner diameter of the shaft tube 70 of the roll 71 on which the wrapping paper 72 is wound is set to a size that can be closely engaged with the side surface of the engagement shaft 104 and can be engaged. Further, on the inner surface of the shaft tube 70, a plurality of engaging grooves 109 having a depth capable of engaging with each of the engaging ridges 107 of the engaging shaft 104 and being inclined in the same direction. (The broken line in FIG. 5 is an imaginary line indicating the engagement groove 109 on the near side.)
[0034]
On the other hand, the guide plate 106 is disposed at a small distance from the base plate 103 as shown in FIG. 5, and corresponds at least below the engagement shaft 104 (in FIG. 5, diagonally below left). When the roll 71 of the wrapping paper 72 is mounted on the mechanism 102, first, the roll 71 is placed on the guide plate 106 as shown in the upper part of FIG. 5, and the shaft tube 70 and the engaging shaft 104 are aligned. In this case, the guide plate 106 may have a curved shape such that a portion corresponding to the engagement shaft 104 is the lowest. With such a configuration, the alignment is further facilitated.
[0035]
When the roll 71 is moved in the direction of the base plate 103 in this state, the inner edge of the upper surface of the lower surface of the shaft tube 70 comes into contact with the tapered portion 108 of the engagement shaft 104 as shown in the upper part of FIG. The positional relationship with the roller 106 is appropriately set according to the size of the roll 71 as described above. When the roll 71 of the wrapping paper 72 is further moved in the direction of the base plate 103, the shaft tube 70 is guided by the tapered portion 109 and lifts away from the guide plate 106. Match. By providing the tapered portion 108 and the guide plate 106 in this manner, the positioning of the roll 71 becomes extremely easy.
[0036]
Next, when the roll 71 is slightly rotated in the direction of the arrow in FIG. 6, the engagement groove 109 on the inner surface of the shaft tube 70 eventually matches the engagement ridge 107 on the engagement shaft 104. When the screw is rotated and pushed in the direction of the arrow in FIG. 6, the engaging ridges 107 enter the engaging grooves 109 and engage detachably (the lower state in FIG. 5). Then, the roll 71 is finally mounted and mounted on the upper surface of the base plate 103.
[0037]
Here, as described above, the engagement protrusions 107 of the engagement shaft 104 extend so as to be inclined in the direction of the base plate 103 toward the rotation direction of the base plate 103 and the engagement shaft 104. As described above, when the wrapping paper 72 is sent out, the force acting on the shaft tube 70 and the engagement shaft 104 acts in the direction of further tightening the meshing engagement between the engagement protrusions 107 and the engagement grooves 109. Thus, the roll 71 can be prevented from falling off even when the engagement shaft 104 has a small protrusion dimension (in the embodiment, the height dimension to the lower end of the tapered portion 109 is 10 mm).
[0038]
In this embodiment, the engagement shaft 104 projects obliquely upward at 45 degrees due to the inclination of the mounting plate 101. However, the present invention is not limited to this, and includes horizontal (in this case, the base plate 103 is in the vertical direction). A structure that projects obliquely upward at a small angle may be used.
[0039]
Next, FIG. 7 shows a view of the roll 71 as viewed straight from the upper left side of FIG. A tension applying mechanism 113 is provided on the mounting plate 101 in a path between the roll 71 and the printer 73. The tension applying mechanism 113 includes a metal base 114 and a rod-shaped body 116 protruding from the base 114 and formed of a metal round bar (circular in cross section) having a dimension sufficiently longer than the width of the wrapping paper 72. A part 121, a pair of rollers 117, 117 protruding from both sides from the base 114, a pair of rails 118, 118 slidably engaged with the rollers 117, 117, and a tension pin 119. I have.
[0040]
The action portion 121 itself has a predetermined weight. In addition, the rails 118 are provided in a direction in which the mounting plate 101 is inclined, and extend from the upper right to the lower left (in the vertical direction, which may be the vertical direction) in FIG. Thus, the action portion 121 including the rod-shaped body 116 is movable vertically by its own weight along the rails 118, 118 by sliding of the rollers 117, 117. The tension pin 119 is located on the upper side of the opposite side of the roll 71 with the rails 118 and 118 interposed therebetween. (FIG. 7). Thereby, substantially equal force is applied to the left and right wrapping paper 72 of the rod-shaped body 116.
[0041]
With the above configuration, the wrapping paper 72 pulled out from the roll 71 passes under the rod 116 of the tension applying mechanism 113 and is routed from the upper side of the tension pin 119 to the printer 73. As a result, the force with which the action portion 121 descends due to its own weight is the force with which the bar-shaped body 116 pushes down the wrapping paper 72, and thus the wrapping paper 72 is given tension.
[0042]
When the wrapping paper 72 is pulled out from the roll 71 by the roller 77 or the like described above, the action portion 121 is lifted by the wrapping paper 72 as shown by a broken line in FIG. When the pulling force decreases, the action portion 121 descends again (a state shown by a solid line in FIG. 7). With this, tension is applied to the wrapping paper 72 to prevent wrinkles. However, as described above, the action portion 121 of the tension applying mechanism 113 moves in the vertical direction and is pulled out by its own weight. Since the tension is applied to the wrapping paper 72, the tension applied to the wrapping paper 72 does not depend on the operating position of the action section 121.
[0043]
This makes it possible to apply a constant tension uniformly to the wrapping paper 72 wound in a roll shape and continuously pulled out, thereby effectively preventing both generation of wrinkles and cutting due to excessive tension. Can be eliminated. In particular, the tension applying mechanism 113 includes an operating portion 121 for pushing down the wrapping paper, rollers 117 and 117 provided on the operating portion 121, and vertical rails 118 and 118 on which the rollers 117 and 117 are slidably engaged. Therefore, the action portion 121 and the rollers 117 and 117 move smoothly along the rails 118 and 118 by their own weights, and can constantly apply a stable tension to the wrapping paper 72.
[0044]
Next, the nozzle 74 is provided substantially vertically as shown in FIG. The nozzle 74 has a rectangular cylindrical shape with an open top and bottom, and its tip (lower part) is moved toward the near side to form a narrow portion 122 having a narrow front and rear width, and the lower end of the narrow portion 122 is opened. (The inside depth of the medicine drop passage at the upper part in the nozzle 74 of the embodiment is 30 mm, and the narrow portion 122 is 18 mm). The wrapping paper 72 usually has a depth (width) of 74 mm and 43 mm, and the narrow width portion 122 is formed so that the nozzle 74 can be inserted even in this shallower wrapping paper 72.
[0045]
A wrapping paper guide 123 is attached to the narrow portion 122 from outside. The wrapping paper guide 123 has a tapered cross-section of substantially V-shape, and is orthogonal to the traveling direction of the wrapping paper 72 (a 45-degree inclined direction from upper left to lower right) (FIG. 9). . The wrapping paper guide 123 has open front and rear surfaces (left and right surfaces in FIG. 4) in the traveling direction of the wrapping paper 72, so that the medicine dropped into the nozzle 74 can pass through the lower front side of the wrapping paper guide 123 (see FIG. 4). 9, it is possible to pass downward from the opening surface (shown by 123A on the lower right side and in FIG. 8 on the near side in FIG. 8) (indicated by a broken arrow in FIG. 9).
[0046]
The upper end opening of the nozzle 74 faces the lower end opening 54A of the hopper 54, and the nozzle 74 is inserted into the wrapping paper 72 from the lower end of the wrapping paper guide 123. In this case, since the wrapping paper guide 123 has a V-shaped cross section, it is easy to insert the wrapping paper 72 from the upper opening side of the half-folded wrapping paper 72 as described above. In this case, if the nozzle 74 is placed so as to be slidable in the traveling direction of the wrapping paper 72, the operation of inserting the wrapping paper guide 123 into the wrapping paper 72 is further facilitated.
[0047]
When the nozzle 74 is inserted into the wrapping paper 72, the wrapping paper 72 expands left and right in the advancing direction as shown by a broken line in FIG. Since the 123 is attached and inserted into the wrapping paper 72, wrinkling and loosening of the wrapping paper 72 are prevented or minimized.
[0048]
When the nozzle 74 is inserted into the wrapping paper 72 in this manner, the medicine received by the hopper 54 enters the nozzle 74, and then passes through the medicine falling passage formed therein to form the medicine of the wrapping paper guide 123. It passes through the opening surface and is put into the wrapping paper 72 (FIG. 9). At this time, since the bottom portion of the wrapping paper 72 is swelled by the wrapping paper guide 123, even if a large amount of medicine is supplied, the inconvenience of loosening and wrinkling is prevented or suppressed.
[0049]
Further, a shutter 126 as shown in FIG. 10 is provided in the nozzle 74 (the wrapping paper guide 123 is omitted in this figure). The shutter 126 has a first shutter plate 128 whose upper end is rotatably driven by a drive shaft 127 located at the upper part on the inner side of the nozzle 74, and a rotation shaft 129 which rotates at the tip of the first shutter plate 128. And a second shutter plate 131 that is freely connected. In addition, a guide groove 132 is formed on the side wall of the nozzle 74 so as to match the rotation locus of the rotation shaft 129 associated with the rotation of the first shutter plate 128.
[0050]
In a state where the first shutter plate 128 of the shutter 126 is rotated upward as shown in FIG. 10, the rotation shaft 129 at the tip abuts on the inner wall of the nozzle 74, whereby the first shutter plate 128 Close the fall path (FIG. 10). At this time, the second shutter plate 131 is suspended by its own weight in a state in which the second shutter plate 131 is slightly inclined inward as shown in FIG.
[0051]
The shutter 126 is for temporarily receiving the medicine discharged from the hopper 54 to the nozzle 74. When the medicine is dropped by opening the shutter 126 during packaging, a first shutter plate 128 is provided with a solenoid or motor (not shown). By means of a driving means such as this, it is rotated counterclockwise in FIG. 10 about the drive shaft 127, and finally changes from the closed state of FIG. 10 to the hanging open state as shown in FIG. In this state, the medicine drop passage in the nozzle 74 is opened. At this time, the tip of the second shutter plate 131 abuts on the corner 122A at the upper end serving as the starting point of the narrow portion 122, and enters a tilted state in which the second shutter plate 131 rotates clockwise about the rotation shaft 129. When the shutter is closed, the first shutter plate 128 is rotated clockwise in each of the drawings by the above-mentioned driving means, and returns to the state shown in FIG.
[0052]
Here, the maximum drug has a length of about 25 mm. Therefore, when the medicine is dropped by opening the shutter 126, if the medicine tries to enter the narrow portion 122 in a substantially horizontal state as shown in FIG. 11, the medicine may be clogged due to its narrow width. At this time, as described above, the second shutter plate 131 contacts the corner 122A of the narrow portion 122 and its lower end is located at the entrance of the narrow portion 122 as shown in FIG. It is on the lower end of the shutter plate 131.
[0053]
When the first shutter plate 128 is rotated in the closing direction from this state, the second shutter plate 131 swings counterclockwise in the drawing from the state shown in FIG. The action force such as lowering the right end of the medicine in the state of FIG. 11 is exerted. As a result, the clogged medicine changes its posture, and falls into the narrow portion 122 as shown in FIG.
[0054]
Although FIG. 11 shows a state in which one medicine is clogged, when several medicines are clogged, the swing of the second shutter plate 131 breaks them. In any case, the structure of the shutter 126 can eliminate a large-sized drug from being clogged. However, if the clogging still does not clear, a control device (not shown) will generate an alarm.
[0055]

【The invention's effect】
As described in detail above, according to the present invention, there is provided a drug supply device that includes a tablet case for storing a medicine and a wrapping paper wound in a roll, and wraps the medicine discharged from the tablet case with the wrapping paper. A wrapping paper delivery mechanism for delivering the wrapping paper. The wrapping paper delivery mechanism engages with a base plate that holds the wrapping paper and that engages with a shaft tube that protrudes from the center of the base plate and around which the wrapping paper is wound. The engaging shaft has an engaging protrusion formed on a side surface of the engaging shaft so as to intersect at a predetermined angle with respect to the axial direction of the engaging shaft. Since the engaging groove is formed so as to be engaged with the engaging ridge, the engaging shaft is inserted into the shaft pipe of the wrapping paper, and the engaging groove is rotated so as to be aligned with the engaging ridge and screwed. Allows the wrapping paper to be mounted on the base plate.
[0062]
Thereby, the mounting workability of the wrapping paper is improved. In particular, since the engaging ridge of the engaging shaft and the engaging groove of the shaft tube engage with each other, the falling off of the wrapping paper can be effectively prevented.
[0063]
According to the invention of claim 2, in addition to the above, the engaging ridge extends from the tip of the engaging shaft toward the base plate while being inclined in the rotation direction of the engaging shaft. Since the rotation when the wrapping paper is pulled out acts in the direction of tightening the engagement between the engaging ridge and the engaging groove, even if the height of the engaging shaft is reduced and the mounting property is improved, Dropping can be reliably prevented.
[0064]
According to the third aspect of the present invention, in addition to the above-mentioned inventions, the wrapping paper sending mechanism is provided with the guide plate for receiving the wrapping paper corresponding to the lower portion of the base plate. Even when the wrapping paper is provided so as to protrude upward, the mounting operation can be performed after the wrapping paper is placed on the guide plate, and the positioning can be easily performed. In addition, since the tip of the engaging shaft is tapered, the tapered shape can be used to guide the shaft tube of the wrapping paper to the engaging shaft, and positioning can be further facilitated.
