Description

The present invention relates to a medicine packaging device.

2. Description of the Related Art Conventionally, as a heat sealing mechanism employed in a medicine packaging apparatus, for example, a rubber table and a heater table are rotatable around a first hinge shaft and a second hinge shaft arranged on the same axis, respectively. Are formed to form a vertical seal portion and a horizontal seal portion (see, for example, Patent Document 1).
JP 2001-31003 A

However, in the heat sealing mechanism of the medicine packaging device, the heater base simply rotates around the second hinge shaft. For this reason, the distance between the packaging sheet and the heater base cannot be sufficiently set before the packing sheet is sandwiched between the rubber table and the heater table, and the packaging sheet may be deformed due to heat. .

Accordingly, it is an object of the present invention to provide a medicine packaging apparatus capable of reliably preventing a wrapping paper from being deformed due to heat during transportation before sealing.

The present invention provides, as a means for solving the above-mentioned problem, a medicine in which a wrapping paper supplied with a medicine is sealed by being sandwiched between a pair of seal blocks from both sides and heated to be packaged one by one. In packaging equipment,
Among the seal blocks, those having a heater can be retracted from the transport path of the wrapping paper to a position where the wrapping paper and the medicine are not adversely affected by heat.

With this configuration, when the medicine is not wrapped, the sheet block having the heater is retracted from the conveyance path of the wrapping paper, so that the wrapping paper and the medicine are not adversely affected by heat, and the next wrapping operation can be smoothly performed. It is possible to resume.

When the hopper for supplying the medicine can be positioned at the center of the transport path of the wrapping paper, and when both the seal blocks can be retracted from the transport path of the wrapping paper, only one side of the wrapping paper is expanded. This is preferable in that the positional displacement of the wrapping paper is less likely to occur, and the medicine can be properly accommodated even when the amount of the medicine is large.

When the wrapping paper is conveyed obliquely downward, and the wrapping paper is sealed by the seal block at a position where two adjacent packets are partitioned and at a side edge that straddles the two adjacent packets, 1 This is preferable in that a medicine supply area capable of supplying the medicine in the package can be secured.

The seal block includes a first seal block having a heater and capable of coming and going in a direction perpendicular to a transport path of the wrapping paper, and rotating in conjunction with the operation of the first seal block. And a second seal block that can be brought into contact with and separated from the transport path of the wrapping paper.

By providing a pair of holding pieces that rotate in conjunction with the rotation of the second seal block and hold the wrapping paper, it is possible to prevent the medicine supplied in the medicine supply area from scattering around. It is preferable in that it becomes.

Preferably, the hopper is provided with an exhaust duct capable of collecting the medicine scattered inside.

The hopper is composed of an upper hopper and a lower hopper in which the upper hopper is housed. When the lower end opening of the upper hopper can be opened and closed by an opening / closing plate, the medicine drops over a long distance and directly drops. This is preferable because it does not reach the wrapping paper and can prevent scattering when dropped.

The lower end hopper lower end opening cylindrical part has a long axis side dimension that matches the seal width, and the opening edge part is curved so as to be depressed at the center part, further preventing scattering of the medicine dropped into the wrapping paper. It is preferable because it becomes possible.

According to the present invention, since the seal block having the heater can be retracted from the transport path of the wrapping paper, the wrapping work can be performed without adversely affecting the wrapping paper and the medicine contained therein by heat.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a medicine packaging device according to the present embodiment. The medicine packaging apparatus includes a powder dispensing unit 1 and a powder packaging unit 2.

As shown in FIG. 2 to FIG. 6, the powder dispensing unit 1 roughly includes a first disk 5, a second disk 6, powder supply devices 7 a and 7 b, and a powder on a table 4 provided on the upper surface of the apparatus main body 3. This is a configuration in which output devices 8 (see FIGS. 4 and 7) are provided.

上面 The upper surface of the apparatus main body 3 is openably covered by an opening / closing door 9, and mounting portions 3a and 3b are formed at two places on both front sides. The placing portions 3a and 3b are used for placing a mortar or the like used for making tablets into a powder form. Guide rails 10 are provided on both sides of the upper surface of the apparatus main body 3. On one guide rail 10, a rack 10 a is provided in front of the apparatus main body 3.

The table 4 is provided so as to be able to be pulled out to the front side of the apparatus main body 3 by sliding in the front-rear direction in a horizontal plane along the guide rail 10. The table 4 is formed with two through holes 11a and 11b and an arc-shaped relief hole 12 respectively.

The first disk 5 and the second disk 6 have an outer peripheral groove 13 having an arc-shaped cross section, and the outer peripheral groove 13 is supplied with powdered medicine. The first disk 5 is provided at a position slightly higher than the second disk 6, and is provided on the table 4 with the outer peripheral portion partially overlapping. This makes it possible to make the entire apparatus compact.

The first disk 5 has a guide edge portion 14 formed in an area including at least a portion of the outer peripheral edge of the first disk 5 that overlaps the second disk 6, and the powdered medicine supplied to the outer peripheral groove 13 of the first disk 5 falls onto the second disk 6. Has been prevented. The first disk 5 is rotatably supported by a substantially fan-shaped intermediate plate 16 about the shaft 5a, and power from the first drive motor 15a is transmitted through a gear 5b. The intermediate plate 16 is provided in the through hole 11a of the table 4 so as to be rotatable about a rotation shaft 16a. The rotating shaft 16a penetrates the table 4, and a gear portion 16b that is partially extended is formed on the outer periphery of the lower end. The gear portion 16b meshes with a rack 10a provided on the guide rail 10 when the table 4 is pulled forward with respect to the apparatus main body 3. As a result, the intermediate plate 16 rotates about the rotation shaft 16a, and the first disk 5 moves accordingly. At this time, the first drive motor 15a is prevented from interfering with the table 4 by the escape hole 12. Since the intermediate plate 16 and the first disk 5 have a structure supported only by the rotary shaft 16a, the auxiliary plate and bearings (not shown) are appropriately provided on the lower surface of the intermediate plate 16 so that the rotary shaft is provided. The load on 16a is reduced. The intermediate plate 16 is locked by a lock mechanism (not shown) such as a solenoid so that the powder cannot be rotated unless the powder supply device 7 is rotated.

The second disk 6 is rotatably supported by the through hole 11b of the table 4. The second disk 6 is rotatable by transmitting power from the second drive motor 15b via a gear 6a.

The powder supply devices 7a and 7b have a conventionally well-known configuration (see, for example, Japanese Patent No. 2669511), and sequentially supply the powder supplied to the hopper to the outer circumferential groove 13 while rotating the disks 5 and 6. The powder supply device 7 a is provided on the table 4 and is movable between a position where powder can be supplied to the outer circumferential groove 13 of the first disk 5 and a position retracted from the first disk 5. Of course, not only the first disk 5 but also the second disk 6 may be movable. This is preferable in that the cleaning property on the table 4 can be further improved.

The scraping device 8 has a conventionally well-known configuration (for example, refer to Japanese Patent Application Laid-Open No. 2000-85719), is disposed at the center of each disk, and scrapes powders stored in the outer peripheral groove 13 of the disk one by one. To fall into the powder packaging section 2.

As shown in FIG. 8, the powder wrapping unit 2 includes a transport unit 19 for automatically transporting the wrapping paper 18 wound around the roll 17 to the powder wrapping unit 2, and a powder pill on the transported wrapping paper 18. And a sealing means 21 for heat-sealing the wrapping paper 18 supplied with the powdered medicine.

As shown in FIGS. 9 and 10, the transporting means 19 has a plurality of transporting rollers 23a, 23b, 23c, 23d, and 23e rotatably disposed between holding plates 22a and 22b arranged at predetermined intervals. The belt 24 is stretched over the transport rollers 23a, 23b, and 23c at the locations, and a guide member 25 is slidably disposed so as to be in contact with and separated from a part of the belt 24. A first motor 26 and a second motor 27 are provided on one end side of the holding plate 22a, respectively. The rotation shaft of the first motor 26 is connected to the transport roller 23a, so that the belt 24 can be circulated. A pinion 28 is integrated with the rotation shaft of the second motor 27. The guide member 25 has a substantially U-shape along a part of the belt 24, a side portion thereof is reinforced by a rectangular frame body 29, and a rack 30 on which a pinion 28 of the second motor 27 meshes is provided on a bottom surface side. I have. The guide member 25 moves toward and away from the belt 24 via the pinion 28 and the rack 30 by driving the second motor 27. The first motor 26 and the second motor 27 are driven and controlled to start driving when a sensor (not shown) detects that the wrapping paper 18 has been inserted into the entrance of the conveying means 19. Further, on / off control and forward / reverse control of the second motor 27 is performed based on a detection signal from a sensor 25b that detects a plate 25a provided on the bottom surface side of the guide member 25, and the movement range of the guide member 25 is limited. You. The inner surface of the guide member 25 is located closest to the belt 24 at the position closest to the belt 24 so that the wrapping paper 18 is sandwiched between the belt 24 and the frictional force between the belt 24 and the wrapping paper 18 is increased. The wrapping paper 18 can be transported. An auxiliary seal portion 100 is provided between the transport rollers 23d and 23e, and the wrapping paper 18 is manually pressed against the auxiliary seal portion 100 by a roller 102 provided at the tip of the arm 101, whereby the wrapping paper 18 is By sticking the tip portion, it is possible to smoothly move from the conveying means 19 to the sealing means 21. A printing device 31 (see FIGS. 8 and 10) is provided above the belt 24 between the transport rollers 23a and 23b so that the name of the medicine to be contained, the usage, the dosage, and the like can be appropriately printed on the wrapping paper 18. It has become. Further, the wrapping paper 18 conveyed along the belt 24 is changed in direction by the guide piece 19a, passes through a substantially U-shaped path formed by the roller 19b and the guide wall 19c, and is connected to the hopper member 20 and the sealing means 21. It is led to.

The hopper member 20 includes a funnel-shaped upper hopper 32 and a lower hopper 33, as shown in FIG. The upper hopper 32 is separated into a tablet passage 32a and a powder passage 32b, and a lower opening of the powder passage 32b is opened and closed by an opening / closing plate. The opening / closing plate 34 opens and closes by transmitting a driving force of a motor 41a to be described later via a timing belt and a timing pulley (not shown). As a result, the powdered medicine supplied from the disks 5 and 6 does not fall over a long distance and directly reach the wrapping paper 18, so that scattering at the time of dropping is prevented. The lower opening cylindrical portion 33a of the lower hopper 33 has a substantially elliptical cross section, the dimension on the long axis side matches the seal width, and the opening edge is curved so as to be depressed at the center. Even with this configuration, the powdered medicine is prevented from scattering around from inside the wrapping paper 18. The powder that has flown into the lower hopper 33 is discharged through the exhaust duct 33b. Further, in order to smoothly discharge air from the exhaust duct 33b, an air introduction hole 33c is formed through a partition wall (not shown) (for preventing powder fall).

As shown in FIGS. 12 and 13, the sealing means 21 is provided with a first seal block 37 and a second seal block 38 provided on a mounting plate 36 constituting a front portion of the apparatus main body 3 so as to be openable and closable. Is attached in a state of being inclined corresponding to the wrapping paper 18 heading toward the center. The mounting plate 36 has first and second support plates 39a and 39b arranged on the back side thereof, and a third support plate 39c is fixed to both the support plates 39a and 39b. The two seal blocks 37 and 38 are separated from each other by a first cam member 40 driven by a first motor 40a and a second cam member 41 driven by a second motor 41a. A substantially T-shaped seal can be provided at a position orthogonal to the folding line and at a position opposite to the folding line. The wrapping paper 18 supplied to the sealing means 21 can be conveyed by being nipped by a pair of delivery rollers 42a and 42b and one of them is rotated by a stepping motor (not shown). The transport amount of the wrapping paper 18 is changed according to the difference in the amount of medicine per package. Here, the carry amount is determined based on the pulse of the stepping motor. Thus, even if a cutter (not shown) is fixed to the mounting plate 36, the wrapping paper 18 can always be cut at an appropriate position.

The first seal block 37 has a substantially T-shaped first heat seal portion 43, and is fixed to one end of a slide shaft 45 that passes through the bearing portion 44 of the mounting plate 36, as shown in FIGS. ing. The first heat sealing section 43 has a built-in heater and heats and seals the wrapping paper 18. A flange 45a is formed at the other end of the slide shaft 45, and a first bearing 46, a second bearing 47, and a third bearing 48 are provided therein. A spring (not shown) is provided between the flange 45a and the bearing 44 of the mounting plate 36. Thereby, the first seal block 37 is positioned at the retracted position close to the mounting plate 36. An arm 49 is provided on the flange 45 a of the slide shaft 45 so as to extend through the mounting plate 36 and extend forward. A first pressing portion 50 and a second pressing portion 51 are formed at the tip of the arm 49 by bearings provided at two places.

The second seal block 38 has a second heat seal portion 52 facing the first heat seal portion 43 of the first seal block 37, and is rotatable by a cover 53 that can be opened and closed to cover both seal blocks 37 and 38. Attached to. That is, the cover 53 is provided with an auxiliary plate 54 that is rotatable about a rotation shaft 54a. The second seal block 38 is urged by the auxiliary plate 54 in the projecting direction via a spring 54b. Is attached. The second seal block 38 is urged toward the cover 53 by a spring (not shown) provided between the auxiliary plate 54 and the cover 53, and abuts on an auxiliary cam 55 rotatably provided on the cover 53. The auxiliary cam 55 has an eccentric shaft portion 56a, and the shaft portion 56a is provided with an auxiliary bearing 56. The auxiliary bearing 56 is slidably positioned in the elongated hole 57a of the auxiliary block 57. The auxiliary block 57 rotates the auxiliary cam 55 about 90 degrees around the shaft 56a by pressing the rod 57b extending therefrom with the first pressing portion 50 of the arm 49. As a result, the second seal block 38 is positioned via the auxiliary plate 54 in parallel with the cover 53 or inclined so as to approach the cover 53 side. The cover 53 is provided with a holding member 58 for holding the wrapping paper 18. The holding member 58 is composed of a pair of holding pieces 59a and 59b provided rotatably about a fulcrum. Pressing portions 60 made of rubber or the like are formed on the opposing surfaces of the holding pieces 59a and 59b, and are rotated synchronously by a gear 61 that meshes with each other. A press receiving portion 62 that is pressed by the first pressing portion 50 of the arm 49 extends on one of the holding pieces 59b.

As shown in FIG. 14, the first cam member 40 is formed in parallel with a first guide wall 63 formed along substantially half of the outer edge and in a range of approximately の of the first guide wall 63. A second guide wall 64 is provided, and is rotatably mounted on the third support plate 39c about the rotation shaft 40b. As shown in FIG. 12, a third support plate 39c is provided on the third support plate 39c via a gear (not shown). The power of one motor 40a is transmitted. Thus, when the first cam motor 65 is driven to rotate forward and reverse, the first cam member 40 is rotated through a drive gear and a driven gear within a range of about 90 degrees based on detection signals from the sensors 49a and 49b. . When the first bearing 46 slides between the two guide walls 63 and 64, the slide shaft 45 slides, and the first seal block 37 approaches the mounting plate 36 in a retracted position, and the mounting plate 36 Reciprocates between the seal preparation position and the seal preparation position.

As shown in FIG. 15, the second cam member 41 has a stepped shape, a rotational center portion 66 is provided eccentrically, and a relief recess 68 is formed by partially cutting off the side surface of the body portion 67. ing. The flange 69 has a guide groove 70 in which the third bearing 48 provided on the slide shaft 45 slides. The guide groove 70 is formed to have the same radius at the center with respect to the rotation center portion 66, and the radius gradually decreases toward the both ends. The second cam member 41 is rotatably provided on a first support plate 39a and a second support plate 39b about a rotation axis, and a driven gear provided on the rotation shaft is a second motor provided on the first support plate 39a. It is in mesh with the drive gear integrated with the rotation shaft of 41a. Thus, when the second motor 41a is driven, the second cam member 41 rotates via the driving gear and the driven gear.

Next, the operation of the medicine packaging apparatus having the above configuration will be described.

First, the folded wrapping paper 18 wound around the roll 17 is supplied to the transporting means 19. When the wrapping paper 18 supplied to the conveying means 19 is detected by the sensor, the first motor 26 is driven and the belt 24 circulates. Further, the second motor 27 is driven and the guide member 25 approaches so as to follow a part of the belt 24. Thereby, the wrapping paper 18 is brought into a press-contact state between the belt 24 and the guide member 25, and is conveyed as the belt 24 moves. The wrapping paper 18 carried out from the transporting means 19 is changed in direction along a substantially U-shaped path formed by the guide pieces 19a, the rollers 19b and the guide walls 19c, and the fold is positioned on the lower side to the wrapping portion. It is led. After the wrapping paper 18 is guided to the wrapping portion, the second motor 27 is driven to separate the guide member 25 from the belt 24. As a result, the load acting on the wrapping paper 18 during wrapping can be reduced, and problems such as tearing can be prevented.

In the powdered medicine packaging section 2, the first cam member 40 is rotated to the position shown in FIG. 12 by driving the first cam motor 40 a to slide the first bearing 46 along the first guide wall 63. Is moved from the space between the two guide walls 63 and 64 to a region where the second guide wall 64 is not provided. Thus, the first seal block 37 advances through the slide shaft 45 to the seal preparation position as shown in FIGS. In this state, the holding pieces 59a and 59b of the holding member 58 are opened, and the second seal block 38 is rotated to the retracted position about the rotary shaft 54a together with the auxiliary plate 54 by the urging force of a spring (not shown). . That is, not only the first seal block 37 but also the second seal block 38 is separated from the transport path of the wrapping paper 18. Therefore, the lower hopper 33 can be located at the center of the transport path, and the wrapping paper 18 can be expanded on both sides. For this reason, compared to the case where only one side of the wrapping paper 18 is inflated as in the related art, the wrapping paper 18 is less likely to be displaced, and the medicine can be properly accommodated even when the amount of medicine is large.

Here, the second cam motor 41a is driven to rotate the second cam member 41. As a result, the radius of curvature of the outer peripheral surface of the body portion 67 of the second cam member 41 changes, so that the second cam member 41 presses the second bearing 47 at the center portion, and passes through the slide shaft 45 for a predetermined time (for example, 0.5 20), the state where the first seal block 37 is advanced to the seal position as shown in FIG. With the movement of the slide shaft 45, the arm 49 provided on the flange 45a moves forward, and the first pressing portion 50 presses the pressing receiving portion 62 of the holding member 58. Thus, the holding pieces 59 of the holding member 58 approach each other, and hold the wrapping paper 18. Further, the second pressing portion 51 presses the auxiliary block 57 via the rod 57b, and rotates the auxiliary cam 55 via the auxiliary bearing 56. As a result, the auxiliary cam 55 presses the auxiliary plate 54, and the auxiliary plate 54 rotates together with the second seal block 38 to the sealing position as shown in FIG. As a result, on the obliquely lower side of the lower hopper 33 located in the folded wrapping paper 18, the wrapping paper 18 is sandwiched by the heat seal portions 43 and 52 of the seal blocks 37 and 38, and is substantially T-shaped, that is, The area between the two adjacent packets and the area slightly more than half of the sides are sealed. On the other hand, the lower hopper 33 is pinched along the lower hopper 33 by a pinching member 58 at a side portion located obliquely above the lower hopper 33. As a result, a powder supply area capable of supplying one package of powder via the lower hopper 33 is secured.

で In this state, powder is supplied from the first disk 5 or the second disk 6 by the scraping device 8 one package at a time based on the prescription data. The supplied powder is once stored in the powder passage 32b of the upper hopper 32 closed by the opening and closing plate 34, and after the scattering of the powder is prevented, the opening and closing plate 34 is opened, as described above. The wrapping paper 18 thus formed is supplied into the powder supply area. In the powdered medicine supply region, as described above, one side of the lower hopper 33 is sealed, and the other side is held by the holding member 58. Therefore, the supplied powdered medicine is prevented from scattering around.

Each time the supply of the powdered medicine to the powdered medicine supply area is completed, the second motor 41a is driven to rotate the second cam member 41 once, and the delivery rollers 42a and 42b are driven to rotate to wrap the wrapping paper 18 by one package. Transport only. As a result, as shown in FIG. 19, the first seal block 37 and the second seal block 38 are both separated from the wrapping paper 18 and the wrapping paper 18 is conveyed in a state where the nip state by the nip member 58 is released. You. Thereafter, packaging of the powder is continued according to the prescription data by the same operation as described above.

When the packaging process is not performed, in the packaging section, the first cam member 40 is rotated to the position shown in FIG. 16 by driving the first cam motor 40a. As shown in FIGS. 16 and 17, the first bearing 46 moves along the second guide wall 64, and the first seal block 37 moves to the retracted position via the slide shaft 45. Therefore, when the first seal block 37 is far from the wrapping paper 18 and the wrapping process is not performed, the adverse effect on the wrapping paper 18 and the medicine can be eliminated by the high-temperature first heat seal portion 43.

If the disk needs to be cleaned, the door 9 is opened and the powder supply devices 7a and 7b are rotated to release the locked state of the intermediate plate 16. The rotation of the powder supply devices 7a and 7b for supplying the powder onto the first disk 5 facilitates cleaning in the area where the powder is most likely to scatter. When the table 4 is pulled out to the front, as shown in FIGS. 3 and 6, the gear portion 16 b provided on the rotating shaft of the first disk 5 meshes with the rack 10 a provided on the guide rail 10, and the table 4 is pulled out. In conjunction with this, the intermediate plate 16 rotates about the rotation axis. Accordingly, the second disk 6 on the intermediate plate 16 rotates about the rotation axis, the overlapping state with the second disk 6 is released, and the first disk 5 moves to a position where it can be easily cleaned. Further, the second disk 6 is also located forward by pulling out the table 4, and the state of overlapping with the first disk 5 has been released, so that the cleaning is easy.
