BACKGROUND OF THE INVENTION
The present invention relates to a medicine packaging device that divides and wraps a medicine such as a powder or a tablet into a medicine container such as a packaging bag for each dose.
[0002]
[Prior art]
Conventionally, as a medicine packaging device that divides and wraps medicines such as powders or tablets, the powder supply part and tablet supply part are arranged at the upper part, and the medicines that are dropped and supplied from the respective supply parts are placed at the lower part. There is known a structure in which a hopper is arranged, and a packaging device is provided below the hopper to divide and pack the medicines one by one with a packaging sheet.
[0003]
In this type of conventional medicine packaging apparatus, there is a structure shown in FIG. 8A as an example of a packaging apparatus for dividing and packaging medicine. In the apparatus shown in FIG. 8 (a), the packaging sheets 100 are sequentially fed out from a packaging sheet roll obtained by winding a long packaging sheet 100 folded in advance along the length direction into a roll shape. While the packaging sheet 100 is intermittently transferred in the length direction (arrow B direction), the vertical seal 101 is formed by sequentially heat-sealing in the width direction at the vertical seal portion made of a hot plate, and adjacent to each other. The medicine inlet 103a of the medicine injection hopper 103 is inserted from above into the compartment 102 formed by the vertical seals 101, 101 having an open top so that the medicine is introduced. The upper opening 102 is continuously heat-sealed by the horizontal seal portion to form the horizontal seal 104. Here, as shown by the arrow C, the medicine injection hopper 103 moves downward when the medicine is put into the compartment 102 so that the drop distance of the medicine is shortened. Later, it is moved upward so that the vertical seal 101 does not interfere with the medicine charging hopper 103 when the packaging sheet 100 is moved.
[0004]
Moreover, the thing of the structure shown by FIG.8 (b) is also known as another example of a packaging apparatus. In the apparatus shown in FIG. 8 (b), a fold forming body 111 that folds the packaging sheet 110 fed from the packaging sheet roll in two along the transfer direction is provided, and a fixed type is provided downstream of the fold forming body 111. A medicine charging hopper 112 is provided, and further on the downstream side, a heat seal device including a heating roll that continuously forms a horizontal seal 113 and a vertical seal 114 on the packaging sheet 110 is provided. Thus, before the compartment 115 is formed by the horizontal seal 113 and the vertical seal 114 by the heat seal device, the medicine is introduced into the compartment 115 from the medicine introduction hopper 112 to continuously form a package. It has become so.
[0005]
[Problems to be solved by the invention]
However, in the structure of the packaging device as in the former (FIG. 8A), in order to move the medicine charging hopper 103 up and down, when the medicine charging hopper 103 moves down, in other words, into the compartment 102. It is necessary to stop the feeding of the packaging sheet 100 at the time of charging the medicine, and the packaging sheet 100 has to be intermittently fed, which becomes a bottleneck in improving the packaging speed.
[0006]
On the other hand, in the structure of the packaging device described in the latter (FIG. 8 (b)), the packaging sheet can be continuously fed, and the above-mentioned problems concerning the packaging speed can be solved. However, in this structure, the wrapping sheet roll can be removed by the fact that the hopper 112 for medicine charging is fixed, the heat seal device is enlarged, and the wrapping sheet 110 needs to be folded in the middle of the transfer. When the packaging sheet 110 is newly loaded into the packaging apparatus after the replacement, it is necessary to place the packaging sheet 110 along the crease forming body 111 or the medicine charging hopper 112 and insert it into a narrow gap in the heat seal apparatus. However, there is a problem that this loading operation becomes extremely difficult.
[0007]
The present invention has been made to solve the problems of each of the conventional techniques, and provides a medicine packaging apparatus that can easily load a packaging sheet and can improve the packaging speed. It is for the purpose.
[0008]

In addition, it is possible to minimize the falling distance of the medicine and to prevent the medicine from being blown up at the time of injection. In addition, after the drug input port of the drug hopper is charged into one drug container,In accordance with the feeding operation of the medicine container, perform a circular motion in substantially the same plane as the medicine container.Since the medicine container can be moved to another medicine container adjacent to the medicine container, the medicine container can be continuously fed without stopping when the medicine is charged, and stable dispensing can be achieved without slowing the packaging speed. Can be implemented.
[0010]
  Next, a medicine packaging device according to the second invention is:
  A longitudinal seal portion that forms a compartment having an open top by sequentially heat-sealing in the width direction while continuously transferring the long packaging sheet folded in the length direction in the length direction; A medicine injection hopper into which the medicine inlet is inserted from the upper opening of the compartment, and a lateral heat-sealing continuously on the upper opening of the compartment after the medicine is introduced from the medicine introduction hopper And a medicine inlet of the medicine injection hopper after the medicine is introduced into one compartment.Perform a circular motion in substantially the same plane as the compartment in accordance with the feeding operation of the compartment.It is configured to be movable in another compartment adjacent to the compartment.
[0011]
  According to the second aspect of the invention, when the medicine is divided and packaged for each dose, the medicine is charged in a state where the medicine inlet of the medicine input hopper is inserted from the upper opening of the compartment. The falling distance of the medicine can be made the minimum distance, and the dispensing at the time of charging can be prevented and stable dispensing can be performed. In addition, after the drug input port of the drug input hopper has injected the drug into one compartmentPerform a circular motion in substantially the same plane as the compartment in accordance with the feeding operation of the compartment.Since it can be moved to another compartment adjacent to the compartment, the packaging sheet need not be stopped when the medicine is charged, and can be continuously fed to increase the packaging speed. In addition, a large heat sealing device that simultaneously performs vertical sealing and horizontal sealing is unnecessary, and a packaging sheet that has been folded in advance can be used. Can be easily performed.
[0012]
  In the second invention, an opening forming means for adsorbing the folded folded packaging sheet from the left and right sides and forming an opening for inserting the drug charging port of the drug charging hopper at the upper part of the packaging sheet Is preferably provided.
[0013]
  In this way,When the packaging sheet wound around the packaging sheet roll in a folded state in advance when the packaging sheet roll is replaced is loaded into the packaging device, the medicine input hopper is retracted upward from the packaging sheet transfer path. Therefore, the packaging sheet can be easily loaded. In addition, after the packaging sheet is loaded, an opening for inserting the medicine inlet of the medicine feeding hopper is formed on the upper part of the packaging sheet by the opening forming means, so that the packaging sheet is charged with static electricity. Even if it is in a state, the packaging sheet can be peeled off to the left and right to reliably form the opening, and the medicine insertion port can be inserted through the opening to perform the packaging operation without any trouble.
[0014]
  here,It is preferable that the opening forming means also serves as sheet pressing means for pressing the upper edge of the packaging sheet when a drug is charged into the compartment from the drug charging hopper. By doing so, the opening forming means provided below the medicine feeding hopper can be used as a sheet pressing means for preventing scattering of the medicine blown up at the time of medicine feeding, and the number of parts is reduced to configure the apparatus. Can be made compact.
[0015]

[0021]
In other words, the first transmission shaft 18 is connected to the output shaft of the motor 15 via the first spur gear mechanism 16 and the clutch 17, and the rotation of the first transmission shaft 18 is orthogonal to the first transmission shaft 18 via the bevel gear. 1 and the rotation of the first feed roller drive shaft 19 is transmitted to the second feed roller drive shaft 21 via the second spur gear mechanism 20, thereby The upper edge of the packaging sheet 2 is gripped by the two pairs of feed rollers 9 and 9 that are arranged to face each other, and the packaging sheet 2 is fed forward.
[0022]
The clutch 17 is connected to a third spur gear mechanism 22 that is driven together with the first transmission shaft 18, and its rotation is transmitted to the second transmission shaft 23, and further, the second transmission shaft 23. Is transmitted to the first rotating shaft 24 of the transverse seal device 7 orthogonal thereto, and the rotation of the first rotating shaft 24 is transmitted to the second rotating shaft 26 via the fourth spur gear mechanism 25, Thus, the vicinity of the upper edge of the packaging sheet 2 is continuously heat-sealed by a pair of heat rollers 7a, 7a arranged to face each other.
[0023]
The rotation of the first rotation shaft 24 is transmitted to a third transmission shaft 27 orthogonal to the bevel gear through the bevel gear, and the rotation of the third transmission shaft 27 is orthogonal to the third transmission shaft 27 through the bevel gear. Of the first rotation shaft 28 and the rotation of the first rotation shaft 28 is transmitted to the second rotation shaft 30 via the fifth spur gear mechanism 29, thereby causing a pair of opposingly arranged pairs. The packaging sheet 2 is continuously heat-sealed at predetermined intervals in the width direction by the heat rollers 5a and 5a. A spur gear mechanism 25A separate from the fourth spur gear mechanism 25 is provided below the first rotary shaft 24 and the second rotary shaft 26. Similarly, the first rotary shaft 28 and the second rotary shaft 30 A spur gear mechanism 29A separate from the fifth spur gear mechanism 29 is provided at the lower portion. These spur gear mechanisms 25A and 29A are not meshed during the packaging operation by the packaging device 1, and when the packaging sheet 2 is mounted, the front heat rollers 5a and 7a are laid down forward to form a fourth spur gear. The mechanism 25 and the fifth spur gear mechanism 29 are configured to be engaged when the meshed state is released. Thus, when the packaging sheet 2 is mounted from above between the pair of heat rollers 5a, 5a; 7a, 7a with the front heat rollers 5a, 7a lying forward, the spur gears are arranged. The heat rollers 5a, 5a; 7a, 7a can be driven by the mechanisms 25A, 29A so that the packaging sheet 2 can be easily mounted and cleaned, and the gears are divided for normal operation and maintenance. Therefore, no excessive load is applied to the gear, and deterioration can be prevented.

On the other hand, a sixth spur gear mechanism 31 is connected to the third spur gear mechanism 22, and a fourth transmission shaft 32 and a fifth spur gear arranged parallel to each other are connected to the sixth spur gear mechanism 31. The transmission shaft 33 is connected, and the transmission shafts 32 and 33 are rotated in the same direction, whereby the rotations are transmitted to the hopper rotation cams 34 and 35, respectively, so that the lower hopper 12 performs a circular motion. .
[0025]
Next, the structure of the rotational drive mechanism of the lower hopper 12 will be described in more detail with reference to FIGS.
[0026]
The hopper rotating cam 34 (the hopper rotating cam 35 has the same structure, so only one will be described) is formed in a rectangular parallelepiped shape as a whole, and a fourth transmission shaft is formed in the upper half portion from the rear side. 32 is fitted and fixed. A rectangular long hole 36 penetrating the front and rear is formed in the lower half portion of the hopper rotating cam 34, and a slide slidable up and down along the inner surface of the long hole 36 is formed in the long hole 36. A moving piece 37 is fitted. The sliding piece 37 is always urged downward by the two compression coil springs 38 and 38, and maintains a state in which the sliding piece 37 is in contact with the lower side of the long hole 36. A shaft body 39 is integrally fixed to the sliding piece 37, and a front end portion of the shaft body 39 is fixed to the back surface portion of the lower hopper 12 through a mounting bracket 40. Thus, when the fourth transmission shaft 32 and the fifth transmission shaft 33 are rotated, the hopper rotation cams 34 and 35 are rotated around the transmission shafts 32 and 33, respectively, at the front end portions of the shaft bodies 39 and 39. The fixed lower hopper 12 performs a circular motion (or a truncated circular motion described later).
[0027]
Above the hopper rotating cams 34 and 35, a rising suppression mechanism is provided that suppresses the lower hopper 12 from rising above a predetermined height. The lift suppression mechanism swings by a lift suppression plate 41 disposed above the hopper rotation cams 34, 35, a motor 42 for moving the lift suppression plate 41 in the vertical direction, and a reciprocating drive of the motor 42. It is comprised by the two rocking bodies 43 and 43 made. In such a configuration, when the rise restraining plate 41 is in the lowest position (solid line position in FIG. 5A), the shaft body 39 is fitted to the front portion of the shaft body 39 when the shaft body 39 is rotated to the upper position. When the roller 44 is in contact with the lower surface of the rise restraining plate 41, the sliding pieces 37, 37 are pushed down against the urging force of the compression coil springs 38, 38, and the predetermined height of the lower hopper 12 is exceeded. The rise of is suppressed. Therefore, the central axis locus of the shaft body 39 at this time has a truncated circular shape as indicated by the symbol P in FIG. On the other hand, when the rise suppression plate 41 is at the uppermost position (the chain line position in FIG. 5A), the roller 44 does not contact the lower surface of the rise suppression plate 41 even if the shaft body 39 rotates to the upper position. Therefore, the sliding pieces 37 and 37 are not pushed downward, and the central axis locus of the shaft body 39 has a circular shape. Here, the rise suppressing plate 41 is raised to the uppermost position when the packaging sheet 2 is set along the transfer path and the medicine packaging operation is started, and is lowered to the lowest position during the packaging operation. . When the ascent restraint plate 41 is in the lowest position, even when the lower hopper 12 is in the highest position, the tip of the medicine inlet 12a overlaps the packaging sheet 2 (in the position of FIG. 7A). The swing stroke of the ascent restraint plate 41 is set so as to come to the hopper position (see hopper position).
[0028]
As shown in FIG. 6, below the lower hopper 12, there is disposed a paper pressing mechanism that serves as both an opening forming means by suction of the packaging sheet 2 and a sheet pressing means by sandwiching the packaging sheet 2. ing. The paper presser mechanism includes a swing shaft 45 that is reciprocally rotated by power from the third transmission shaft 27 (see FIG. 3), and a pair of fan-shapes that mesh the swing motion of the swing shaft 45 with each other. By converting the left and right paper pressers 48, 48 into swinging motions with the gears 46, 47, the upper ends of the paper pressers 48, 48 can be brought close to and separated from the packaging sheet 2. Yes. Each paper presser body 48 includes a substantially U-shaped machine body 48a disposed so as to straddle the medicine inlet 12a of the lower hopper 12, and a cylindrical abutment projecting inwardly at each upper end portion of the machine body 48a. And a contact body 48b. Here, the contact body 48 b is connected to the suction pipe 49, and the contact body 48 b also serves to suck the packaging sheet 2 by sucking air through the suction pipe 49. In addition, this suction pipe 49 is connected to a dust collector for cleaning or a manual dust collector (equipped as standard) disposed on the upper part of the V soot or the split soot in the powder supply unit (not shown), It is preferable to use it by switching with a valve or the like.
[0029]
Next, operation | movement of the packaging apparatus 1 which consists of the above-mentioned structure is demonstrated.
[0030]
First, when the packaging sheet 2 is initially set in the packaging device 1, a printing roller (not shown) in the printing device 4, a heat roller 5 a of the vertical sealing device 5, a heat roller 7 a of the horizontal sealing device 7, and a paper presser. With the upper part of the contact body 48b and the like of the 48 opened, the leading end of the packaging sheet 2 is pulled out from the packaging sheet roll 3, and the packaging sheet 2 is mounted from above the transfer path. At this time, the elevation suppressing plate 41 is in a state where it is raised to the uppermost position (the chain line position in FIG. 5A), and the medicine inlet 12a of the lower hopper 12 is in a position that does not interfere with the upper edge of the packaging sheet 2. .
[0031]
When the packaging sheet 2 is set in a predetermined position in this manner, the printing roller, the heat rollers 5a, 7a, etc. are returned to the predetermined operation position, the motor 15 is driven, and a suction device (not shown) is operated to draw in the suction pipe 49. Then, air is sucked from the tip of the contact body 48b. Thereby, each contact body 48b is swung to a position close to the surface of the packaging sheet 2, and the upper edge portion of the packaging sheet 2 in the folded state is sucked by the contact body 48b, and in this suction state, they face each other. When the contact bodies 48b at the positions are separated from each other, the upper portion of the packaging sheet 2 is peeled left and right to form an opening.
[0032]
In accordance with this operation, the lower hopper 12 moves downward and the tip of the medicine inlet 12a is inserted from the upper opening of the packaging sheet 2, and the suction device is inactivated in conjunction with this insertion operation. At the same time, the paper pressing mechanism is swung to the holding position of the packaging sheet 2. Further, the lift suppression plate 41 is moved to the lowest position (solid line position in FIG. 5A) by the operation of the motor 42 in the lift suppression mechanism.
[0033]
After the initial setting as described above, tablets and / or powders (hereinafter, only when powder is supplied) from the tablet supply unit and / or the powder supply unit will be used for the upper hopper 10 and the lower hopper 12. Then, the packaging operation is proceeded by being supplied into the compartment of the packaging sheet 2.
[0034]
FIG. 7 shows the procedure of this packaging operation (note that FIG. 7 shows the packaging procedure in the middle of packaging). In this packaging, the packaging sheet 2 is sequentially melted in the width direction at predetermined intervals by the heat roller 5a of the vertical sealing device 5 while continuously transporting the packaging sheet 2 in the length direction (arrow X direction). The vertical seal portions 50 and 50 are formed to form a compartment 51 having an upper portion opened by the vertical seal portions 50 and 50 and the folded portion of the packaging sheet 2. The vertical seal 50 is formed so that the upper edge of the packaging sheet 2 remains slightly.
[0035]
The lower hopper 12 descends while making a circular motion in the compartment 51, and powder is put into the compartment 51 in accordance with the descending motion (FIGS. 7A and 7B). When the lower hopper 12 reaches the lowest lowered position, the powder charging operation is completed, and the lower hopper 12 thereafter moves forward and upward in accordance with the forward movement of the packaging sheet 2 (FIGS. 7C and 7D). ). The contact body 48b of the paper pressing mechanism swings to the holding position of the packaging sheet 2 in conjunction with the powder charging operation, thereby suppressing scattering due to blowing up during the powder charging operation.
[0036]
Subsequently, as the lower hopper 12 reaches the highest position, the vertical seal portion 50 on the upstream side of the lower hopper 12 passes under the lower hopper 12, in other words, the compartment in which the lower hopper 12 is adjacent. Then, the lower hopper 12 moves to the upper side of the adjacent compartment 51 as the packaging sheet 2 moves forward. Next, the charging operation into the adjacent compartment 51 is started. Further, the upper edge portion of the compartment 51 to which the powder has already been charged is continuously sealed by forming the horizontal seal portion 52 continuously by the heat roller 7a of the horizontal seal device 7.
[0037]
According to the packaging device 1 of the present embodiment, the packaging sheet 2 folded in two at the time of replacement of the packaging sheet 2 can be easily loaded from above the packaging device 1, and the conventional device shown in FIG. Thus, when loading the packaging sheet, it is not necessary to pass through a narrow gap between the heat seal devices or the lower portion of the fixed hopper device, and the loading operation can be greatly simplified. Further, unlike the conventional apparatus shown in FIG. 8A, it is not necessary to stop the sheet feeding every time the hopper is moved down, and the packaging sheet 2 can be continuously fed, so that the packaging speed is increased. be able to. In addition, the medicine fall distance from the hopper can be minimized when the medicine is charged, and the upper edge of the packaging sheet 2 is securely held by the paper pressing mechanism, thereby preventing scattering due to blowing up when the medicine is charged. And stable dispensing can be performed.
[0038]
In the present embodiment, the vertical seal device 5 and the horizontal seal device 7 are configured to be driven in conjunction with each other, but the drive systems of these seal devices 5 and 7 can also be separated. When the drive systems are separated in this way, it is preferable that the seal width (the width of the compartment) can be freely changed by changing the drive timing of the vertical seal device 5 and the horizontal seal device 7.
[0039]
In this embodiment, the paper pressing mechanism that serves as both the opening forming means and the sheet pressing means can be mounted not only on the wrapping apparatus in which the hopper moves circularly as in this embodiment, but also in FIG. Even if it is mounted on an intermittent drive type packaging apparatus as shown, it is possible to obtain desired actions and effects.
[0040]
In this embodiment, a description has been given of a case in which a required portion of a packaging sheet is heat-sealed to form a compartment for storing a medicine. However, as in the present invention, the medicine is placed while the medicine feeding hopper performs a circular motion. The medicine packaging apparatus having the above structure can be applied to an apparatus having a structure in which the medicine containers are continuously supplied separately from each other. Even when applied to such an apparatus, it is possible to minimize the drop distance of the medicine, prevent the blow-up at the time of charging, and to continuously feed the medicine container, The effect is that the speed can be increased.
