(Dimensions between them).

After the wrapping paper 20 is thermally welded by the heat sealing mechanism 27, the wrapping roller 30 is rotated to move a predetermined distance toward the drawing roller 30 (in the direction of the arrow in FIG. 14). It moves to the main heater 29 (from the folded portion 20A to the heat welded portion of the main heater 29 from the opening 20B). Then, the wrapping paper 20 is thermally welded by the main heater 29, so that the temporary heater 28 and the main heater 29 are sequentially heated.
36A provided with an opening 20B between vertical portions 29A
Is formed, and a small bag 36 is formed on the drawing roller 30 side except for the folded portion 20A, where the small bag 36 is heat-welded.

When the main heater 29 heat-welds the wrapping paper 20 above the temporary heater 28 from the folded portion 20A to the opening 20B, the main heater 29 substantially centers the width of the heat-welded portion (from the folded portion 20A to the opening 20B). ) Is formed with a plurality of perforated holes 37. Thereby, the three sides of the wrapping paper 20 (the other one is the folded part 20A) are thermally welded, and the small bag 3 whose entire circumference is closed
6 are formed, and the small bag 36 can be separated from the cut of the perforated hole 37. A printer (not shown) is provided in front of the tension roller 26, and prints the product name, usage, and the like of the solid preparation to be packed for each small bag 36.

Next, the operation of the solid preparation packaging apparatus 1 of the present invention having the above configuration will be described. It is assumed that the wrapping paper 20 as described above is loaded in the storage case 15, and the delivery motor 18, the drawing motor 31, and the tension roller 2
The switch 6 is connected to the control device 35. Then, for example, when the storage case 15 is loaded at a predetermined position, a switch (not shown) is turned on, and the control device 35
It is assumed that power is supplied to 8, 31. At this time, the fitting shaft 19 of the delivery motor 18 enters through the through hole on the lower surface of the storage case 15 and fits with the hollow shaft 21 of the wrapping paper 20.

With this configuration, the wrapping paper 20 on which the delivery motor 18 rotates rotates and the delivery port 16B of the storage case 15 rotates.
The wrapping paper 20 is sent out, and the hard portion 20C formed at the tip of the wrapping paper 20 moves between the guide plates 24 of the guide rail 23 in the direction of the bent portion 24A. The rigid portion 20C of the wrapped paper 20 is sent to the bent portion 2 of the guide rail 23.
When it reaches 4A, it reaches the draw-in roller 30 from there along the bent portion 24A and between the temporary heater 28 and the main heater 29 (the wrapping paper 20 indicated by a dotted line in FIG. 12).

When the wrapping paper 20 is delivered to the pull-in roller 30, the rubber rollers 33 and 33A of the pull-in roller 30 pull the wrapping paper 20 in the direction opposite to the guide rail 23 (front side) while pressing against each other. The wrapping paper 20 is drawn into the draw-in roller 30, and the leading end thereof is drawn out from the outlet 77 formed in the lower door 5 toward the near side. In this case, since the rigid portion 20C is provided at the end of the wrapping paper 20, the wrapping paper 20 sent out from the storage case 15 is easily bent and protrudes from the guide rail 23, the temporary heaters 28, and the main heater 29. It is possible to reach the pull-in roller 30 without performing. This makes it possible to guide and attach the wrapping paper 20 to a predetermined position without human intervention.

Here, the sending motor 18 and the retracting motor 31
Rotation of the wrapping paper 20 drawn in by the draw-in roller 30 is larger than the moving amount of the wrapping paper 20 sent out from the storage case 15, and a predetermined tension is applied between the storage case 15 and the draw-in roller 30. Is occurring. Thereby, the wrapping paper 20 located between the guide rail 23 and the temporary heater 28 acts inside between the inner guide plate (not shown) and the temporary heater 28. That is, the tension roller 26 is connected to the guide rail 2.
3 (guide plate 24) is moved in a direction away from the bent portion 24A (in the direction of the solid line arrow in FIG. 12).

The movement of the tension roller 26 is detected by the switch, and the control device 35 sends the output motor 1
8 and the pull-in motor 31 are stopped. In this state, the opening 2 of the small bag 36A between the temporary heater 28 and the main heater 29 is opened.
0B each shutter plate 72, 73 of the shutter device 71
Are inserted (FIG. 11).
The filling port 13 of the lower hopper member 41 is slightly spaced above the wrapping paper 20 as shown in FIG.

The control device 35 once detects the movement of the tension roller 26 and detects the movement of the tension motor 26 and the feed motor 18 and the pull-in motor 3.
When 1 is stopped, the feeding motor 18 is not energized and only the pull-in motor 31 is rotated until the wrapping paper 20 is next loaded.

As described above, when the storage case 15 containing the wrapping paper 20 having the rigid portion 20C formed at the tip is loaded at a predetermined position of the solid pharmaceutical product packaging mechanism 14, the wrapping paper is automatically automatically used without using a hand. 20 is fed out and can be mounted from the guide rail 23 to the draw-in roller 30 through the heat sealing mechanism 27. Therefore, it is possible to eliminate the trouble of mounting the roll-shaped wrapping paper by hand over a long period of time and passing it through the predetermined position as in the related art, and almost no mounting failure of the wrapping paper 20 and the like. The replacement time can be greatly reduced.

After the wrapping paper 20 is attached, when the power of the solid preparation packaging apparatus 1 is turned on, the count value for counting the number of drops of the solid preparation is reset. The temporary heater 28 and the main heater 29 are heated to a predetermined temperature, and the conveyor 52 is energized and driven.

An operator can input an input device (not shown) (not shown) based on a doctor's prescription.
And the discharge drum of the tablet case 6 containing the solid preparation is driven to rotate,
Solid preparations of the type specified by the prescription data fall onto the hopper 51 or the conveyor 52 one by one. Further, the solid preparation from the sub-storage unit 7 also falls onto the conveyor 52 by the user's arbitrary operation.

The number of solid preparations falling from the tablet case 6 is counted by the control device 35 based on the output of the photosensor, and when the counted number of dropped solid preparations matches the number of solid preparations based on the prescription data, The rotation of the discharge drum is stopped, and the drop of the solid preparation ends.

At this time, the solid preparation falls directly into the lower hopper member 41 from the tablet case 6 above the lower hopper member 41. Further, the solid preparation dropped on the right hopper member 53 falls into the lower hopper member 41 due to its inclination. Further, the solid preparation dropped on the left and right front hopper members 56 and 57 drops on the elastic sheet 61 of the conveyor 52 due to the inclination. Then, it is sent out into the lower hopper member 41 together with the solid preparation directly dropped on the elastic sheet 61.

Here, since the conveyor 52 is inclined, the solid preparation on the elastic sheet 61 is sent to the lower hopper member 41 by the inclination and the conveying force of the conveyor 52 itself. In particular, since the conveyor 52 is inclined, it is possible to prevent or suppress a cylindrical tablet or the like from idling on the elastic sheet 61.

Further, since the curtain 63 is suspended above the lower hopper member 41, the solid preparation discharged from the conveyor 52 and flying toward the right hopper member 53 falls on the curtain 63 and falls downward. Further, the solid preparation discharged from the conveyor 52 tends to rotate spirally along the inner surface of the lower hopper member 41. However, since the ridges 59 are formed on the inner surface of the lower hopper member 41, the ridges 59 are formed. And falls in the direction of the filling port 13 as it is.

Thus, the time during which the solid preparation is collected in the filling port 13 can be reduced. In addition, debris (powder of medicine and shavings on the surface of the elastic sheet 61) on the conveyor 52 at a portion that sinks below the hopper members 56 and 57 is conveyed before and after coming off the filling port 13, and the powder receiving members 64 and 64.
Received by Thus, the amount of waste packaged with the solid preparation can be reduced, and the contamination inside the device can be reduced.

The solid preparations thus collected in the lower hopper member 41 are once held on the horizontal surfaces 72A, 73A of the shutter plates 72, 73 of the shutter device 71.

When all of the solid preparation for one dose is held on the shutter plates 72, 73, the vertical surfaces 72B, 73B of the shutter plates 72, 73 are driven to be separated. By the operation of the shutter plates 72 and 73, the opening 20B of the small bag 36A is largely opened as shown in FIG. At the same time, since the horizontal surfaces 72A and 73A are separated outward from the filling port 13, the solid preparation collected in the lower hopper member 41 is thrown into the pouch 36A of the wrapping paper 20 located below.

As described above, since the opening 20B of the small bag 36A is opened by the shutter plates 72 and 73 and the solid preparation is supplied, the solid preparation can be reliably and smoothly filled into the wrapping paper 20. . Also, the shutter plate 7
The reference numerals 2 and 73 also serve to temporarily hold the solid preparation dropped by closing the filling port 13, so that the number of parts can be reduced.

After the solid preparation is stored in the small bag 36A of the wrapping paper 20, the shutter device 71 closes the filling port 13 again by the horizontal surfaces 72A and 73A of the shutter plates 72 and 73. At the same time, the vertical surfaces 72B and 73B also come into close contact with each other, so that the opening 20B of the wrapping paper 20 is also closed by the urging force of the tension roller 26 (actually, the vertical surfaces 72B and 73B are open by the thickness thereof. Since the thickness is extremely small, the opening 20B is substantially closed.) Next, the draw-in roller 30 is operated by the control device 35 to pull the wrapping paper 20, and the heat sealing mechanism 2
At 7, the opening 20 </ b> B of the wrapping paper 20 is sealed by heat welding as described above.

As described above, since the opening 20B of the wrapping paper 20 is closed by the shutter plates 72 and 73 after the filling of the solid preparation, the occurrence of displacement of the upper part of the folded wrapping paper 20 is reduced, and wrinkles during heat welding are reduced. It becomes difficult to do. Further, since the filled solid preparation also becomes difficult to move in the small bag 36A, the risk of the solid preparation being caught in the heat sealing mechanism 27 during heat welding and being crushed is reduced.

Further, the temporary heater 2 of the heat sealing mechanism 27
8 is heat-welded from the folded portion 20A side of the wrapping paper 20 to almost the middle between the opening portions 20B side, and the upper portion is not heat-welded.
Without raising the shutter device 71, the wrapping paper 20
Can be drawn in by the drawing roller 30. When the movement of the wrapping paper 20 is stopped, the wrapping paper 20 is again heat-sealed by the main heater 29, and the solid preparation is wrapped in the small bag 36, and at the same time, the shutter device 71 is opened, and the solid of the next dose is solidified. The preparation is smaller than the lower hopper member 41 in the pouch 36A.
It is stored inside. By repeating this, a predetermined number of solid preparations based on the prescription data are automatically packed.

In the embodiment, the vertical surfaces 72B and 73B of the shutter plates 72 and 73 of the shutter device 71 are
The opening 20B is opened and closed by inserting them into the inside of the wrapper 20 and separating and contacting them. However, the present invention is not limited to this. The opening 20 </ b> B may be opened and closed by approaching. According to such a configuration, it is also possible to completely close the opening 20B after filling the solid preparation.

[0065]

As described above in detail, according to the present invention, the shutter device for opening and closing the filling port expands the opening of the wrapping paper in conjunction with the opening of the opening, so that the solid preparation can be reliably and smoothly. Can be filled into the wrapping paper. Further, since the shutter device also has a role of closing the filling port and temporarily holding the dropped solid preparation, the number of parts can be reduced.

In particular, the wrapping paper is separated from the filling port,
After the filling of the solid preparation, the opening of the wrapping paper is closed as the shutter device closes the filling port, and in that state, the occurrence of displacement of the wrapping paper is prevented or suppressed. Therefore, the inconvenience of wrinkling of the wrapping paper during the heat welding is also prevented or suppressed. Furthermore, since the filled solid preparation also becomes difficult to move in the wrapping paper, the risk of the solid preparation being crushed during heat welding is reduced.
