Description

  The present invention relates to a medicine packaging apparatus.

Conventionally, as a heat seal mechanism employed in a medicine packaging device, for example, a rubber base and a heater base are rotatable around a first hinge shaft and a second hinge shaft arranged on the same axis, respectively, and a packaging sheet Is used 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 only rotates around the second hinge shaft. For this reason, before the packing sheet is clamped by the rubber table and the heater table, a sufficient distance between the packing sheet and the heater table cannot be secured, and the packing sheet may be deformed by the influence of heat. .

  Then, this invention makes it a subject to provide the chemical | medical agent packaging apparatus which can prevent reliably that a wrapping paper receives the influence of heat during conveyance before sealing, and deform | transforms.

As a means for solving the above problems, the present invention provides:
In the medicine packaging apparatus in which the wrapping paper supplied with the medicine is sandwiched from both sides by a pair of seal blocks and heated to be sealed and packaged one by one,
The seal block can be moved to a seal position where the wrapping paper can be sandwiched and heated and a seal preparation position where the wrapping paper can be separated so as to be transported,
Among the seal blocks, those having a heater can be moved further away from the seal preparation position, from the transport path of the wrapping paper to a retreat position that does not adversely affect the wrapping paper and the medicine,
The seal block is
A first seal block having a heater and movable to a seal position, a seal preparation position, and a retracted position by contacting and separating in a direction perpendicular to the conveyance path of the wrapping paper;
When the first seal block moves between the seal position and the seal preparation position, the first seal block rotates in conjunction with the rotation axis, contacts and separates from the wrapping paper conveyance path, and the seal position and the seal preparation position And a second seal block that is movable .

  With this configuration, when the medicine is not packaged, the next block of work can be performed smoothly by retracting the sheet block with the heater from the wrapping paper conveyance path without adversely affecting the wrapping paper or medicine. It is possible to resume.

  The first seal block is movable to a seal position, a seal preparation position, and a retracted position via a slide shaft provided movably on the mounting plate.
  It is preferable that the second seal block is rotatable between a seal position and a seal preparation position by being pressed on the rotating shaft side by an arm that moves together with the slide shaft.

The wrapping paper is provided with a pair of clamping pieces that can be clamped by rotating synchronously ,
In addition to the second seal block, the arm that moves together with the slide shaft is preferably configured to operate the second seal block and the clamping piece in synchronization by pressing and rotating the clamping piece.

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

  Embodiments according to the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows a medicine packaging apparatus according to this embodiment. This medicine packaging apparatus includes a powder distribution unit 1 and a powder packaging unit 2.

  As shown in FIGS. 2 to 6, the powder distribution unit 1 is roughly arranged on the table 4 provided on the upper surface of the apparatus body 3, on the first disk 5, the second disk 6, the powder supply devices 7 a and 7 b, and the scratches. The dispensing device 8 (see FIGS. 4 and 7) is arranged.

  The upper surface of the apparatus body 3 is covered with an opening / closing door 9 so as to be openable, and mounting portions 3a and 3b are formed at two locations on both sides of the front. The mounting portions 3a and 3b are used for mounting a mortar or the like that is used for making a tablet into a powder form. Further, guide rails 10 are disposed on both sides of the upper surface of the apparatus body 3. One guide rail 10 is provided with a rack 10 a on the front side of the apparatus 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 the horizontal plane along the guide rail 10. The table 4 is formed with two through holes 11a and 11b and an arc-shaped escape hole 12 respectively.

  The first disk 5 and the second disk 6 include an outer peripheral groove 13 having an arc-shaped cross section, and powder is supplied to the outer peripheral groove 13. 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. Thereby, it is possible to make the whole apparatus compact.

  The first disc 5 has a guide edge 14 formed in a region including at least an overlapping portion of the outer peripheral edge with the second disc 6, and the powder supplied to the outer peripheral groove 13 of the first disc 5 falls to the second disc 6. Is prevented. The first disk 5 is rotatably supported by a substantially sector-shaped intermediate plate 16 around the shaft portion 5a, and the power from the first drive motor 15a is transmitted through the gear 5b. The intermediate plate 16 is provided in the through hole 11a of the table 4 so as to be rotatable about the rotation shaft 16a. The rotating shaft 16a penetrates the table 4, and a gear portion 16b that extends partially is formed on the outer periphery of the lower end. The gear portion 16 b meshes with a rack 10 a 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 15 a is prevented from interfering with the table 4 by the escape hole 12. Since the intermediate plate 16 and the first disk 5 are supported only by the rotary shaft 16a, an auxiliary plate, a bearing, or the like (not shown) is appropriately provided on the lower surface of the intermediate plate 16, thereby rotating the rotary shaft. The burden on 16a is reduced. Further, the intermediate plate 16 is locked by a locking mechanism (not shown) such as a solenoid so that it cannot be rotated unless the powder supply device 7 is rotated.

  The second disk 6 is rotatably supported in the through hole 11 b of the table 4. The second disk 6 can be driven to rotate by transmitting power from the second drive motor 15b via the gear 6a.

  The powder supply devices 7a and 7b have a conventionally known configuration (for example, refer to Japanese Patent No. 2669511), and sequentially supply the powder supplied into 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 peripheral groove 13 of the first disk 5 and a position where the powder is 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 (see, for example, Japanese Patent Application Laid-Open No. 2000-85719), and is disposed at the center of each disk, and scrapes the powder contained in the outer peripheral groove 13 of the disk one by one. Then drop it into the powder packaging part 2.

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

  As shown in FIGS. 9 and 10, the transport unit 19 includes a plurality of transport rollers 23a, 23b, 23c, 23d, and 23e rotatably arranged between holding plates 22a and 22b arranged in parallel at predetermined intervals. The belt 24 is bridged between the conveying rollers 23a, 23b, and 23c at the location, and the 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. The rotating shaft of the first motor 26 is connected to the conveying roller 23a, and the belt 24 can be circulated and moved. A pinion 28 is integrated with the rotation shaft of the second motor 27. The guide member 25 is substantially U-shaped along a part of the belt 24, the side portion is reinforced by a rectangular frame body 29, and a rack 30 with which the pinion 28 of the second motor 27 is engaged is provided on the bottom surface side. Yes. The guide member 25 contacts and separates from the belt 24 through the pinion 28 and the rack 30 by driving the second motor 27. The first motor 26 and the second motor 27 are controlled so as to start driving when it is detected by a sensor (not shown) that the wrapping paper 18 has been inserted into the entrance of the conveying means 19. The second motor 27 is on / off controlled and forward / reversely controlled 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. The The inner surface of the guide member 25 is positioned closest to the belt 24 to sandwich the wrapping paper 18 between the belt 24 and increase the frictional force between the belt 24 and the wrapping paper 18. The wrapping paper 18 can be conveyed. An auxiliary seal portion 100 is provided between the transport rollers 23d and 23e, and the wrapping paper 18 is pressed against the auxiliary seal portion 100 by a roller 102 manually provided at the tip of the arm 101. It is possible to make the movement from the conveying means 19 to the sealing means 21 smoothly by sticking the tip portion. In addition, 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 accommodated, usage, 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 redirected by the guide piece 19a, passes through a substantially U-shaped path formed by the roller 19b and the guide wall 19c, and the hopper member 20 and the sealing means 21. Led to.

  As shown in FIG. 11, the hopper member 20 includes a funnel-shaped upper hopper 32 and a lower hopper 33. The upper hopper 32 is separated into a tablet passage 32 a and a powder passage 32 b, and a lower opening portion of the powder passage 32 b is opened and closed by an opening / closing plate 34. The opening / closing plate 34 opens and closes when a driving force of a motor 41a described later is transmitted through a timing belt and a timing pulley (not shown). As a result, the powder supplied from the disks 5 and 6 does not fall over a long distance and reach the wrapping paper 18 directly, and 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 major axis side dimension matches the seal width, and the opening edge is curved so as to be recessed at the center. Also with this configuration, the powdered medicine is prevented from being scattered from the inside of the wrapping paper 18. Note that the powder that has risen into the lower hopper 33 is discharged through the exhaust duct 33b. Further, in order to smoothly discharge the air from the exhaust duct 33b, an air introduction hole 33c is formed with a partition wall (not shown) (not shown) for separating the powder.

  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 that can be opened and closed on a mounting plate 36 that constitutes a front surface portion of the apparatus body 3. It is attached in an inclined state corresponding to the wrapping paper 18 heading toward the front. The mounting plate 36 has first and second support plates 39a and 39b arranged in parallel on the back surface, and a third support plate 39c is fixed to both the support plates 39a and 39b. Both the seal blocks 37 and 38 are formed by folding the wrapping paper 18 folded in two by bringing the sealing surface into contact with and separating from the first cam member 40 driven by the first motor 40a and the second cam member 41 driven by the second motor 41a. It can be sealed in a substantially T-shape at a position orthogonal to the fold line and at a position on the opposite side. Further, the wrapping paper 18 supplied to the sealing means 21 can be conveyed by being sandwiched between a pair of delivery rollers 42a and 42b and rotationally driven by a stepping motor (not shown). The conveyance 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. Thereby, even if the 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 portion of the slide shaft 45 that penetrates the bearing portion 44 of the mounting plate 36 as shown in FIGS. 11 and 13. ing. The first heat seal part 43 incorporates a 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 there. A spring (not shown) is disposed between the flange 45a and the bearing portion 44 of the mounting plate 36. As a result, the first seal block 37 is positioned at the retracted position close to the mounting plate 36. In addition, an arm 49 that extends forward through the mounting plate 36 is provided on the flange portion 45 a of the slide shaft 45. 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 locations.

  The second seal block 38 has a second heat seal portion 52 that faces the first heat seal portion 43 of the first seal block 37, and is freely rotatable to an openable / closable cover 53 that covers both the seal blocks 37 and 38. Is attached. That is, the cover 53 is provided with an auxiliary plate 54 so as to be rotatable about the rotation shaft 54a. The second seal block 38 is urged by the auxiliary plate 54 in the protruding direction via the 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 comes into contact with an auxiliary cam 55 provided rotatably on the cover 53. The auxiliary cam 55 includes an eccentric shaft portion 56a, and an auxiliary bearing 56 is provided on the shaft portion 56a. The auxiliary bearing 56 is slidably positioned in the elongated hole 57 a of the auxiliary block 57. The auxiliary block 57 rotates the auxiliary cam 55 in the range of about 90 degrees around the shaft portion 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 while being inclined in parallel with the cover 53 or so as to approach the cover 53 side. Further, the cover 53 is provided with a holding member 58 for holding the wrapping paper 18. The clamping member 58 includes a pair of clamping pieces 59a and 59b provided so as to be rotatable about a fulcrum. A pressure contact portion 60 such as rubber is formed on the opposing surfaces of the sandwiching pieces 59a and 59b, and rotates synchronously by a gear portion 61 that meshes with each other. A pressing receiving portion 62 that is pressed by the first pressing portion 50 of the arm 49 is extended on one of the clamping pieces 59b.

  As shown in FIG. 14, the first cam member 40 is formed in parallel with the first guide wall 63 formed along substantially half of the outer edge and in the range of about 2/3 of the first guide wall 63. And a second guide wall 64. The second guide wall 64 is attached to the third support plate 39c so as to be rotatable about the rotation shaft 40b. As shown in FIG. 12, the 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. As a result, when the first cam motor 65 is driven to rotate forward and backward, the first cam member 40 rotates in a range of about 90 degrees based on the detection signals from the sensors 49a and 49b via the drive gear and the driven gear. . Then, when the first bearing 46 slides between the guide walls 63 and 64, the slide shaft 45 slides and the first seal block 37 approaches the mounting plate 36, and the mounting plate 36. It moves back and forth between the seal preparation position projecting from.

  As shown in FIG. 15, the second cam member 41 has a stepped shape and is provided with an eccentric rotation center portion 66, and a relief recess 68 is formed by partially cutting the side surface of the body portion 67. ing. A guide groove 70 in which a third bearing 48 provided on the slide shaft 45 slides is formed in the flange portion 69. The guide groove 70 is formed with the same radius at the central portion with respect to the rotation center portion 66, and the radius gradually decreases as the distance from the both ends increases. The second cam member 41 is provided on the first support plate 39a and the second support plate 39b so as to be rotatable about the rotation shaft, and a driven gear provided on the rotation shaft is provided in the second motor provided on the first support plate 39a. It meshes with a drive gear integrated with the rotating shaft 41a. Thus, when the second motor 41a is driven, the second cam member 41 is rotated via the drive 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 conveying 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 to approach the guide member 25 along a part of the belt 24. Thus, the wrapping paper 18 is brought into a pressure contact state between the belt 24 and the guide member 25 and is conveyed according to the movement of the belt 24. The wrapping paper 18 carried out from the conveying means 19 changes its direction along a substantially U-shaped path formed by the guide piece 19a, the roller 19b, and the guide wall 19c, and enters the wrapping portion so that the crease is positioned on the lower side. It is guided. After the wrapping paper 18 is guided to the packaging portion, the second motor 27 is driven to separate the guide member 25 from the belt 24. Thereby, the load which acts on the wrapping paper 18 at the time of packaging can be reduced, and it becomes possible to prevent malfunctions, such as a tear.

  In the powder packaging part 2, the first bearing 46 is slid along the first guide wall 63 by driving the first cam motor 40a and rotating the first cam member 40 to the position shown in FIG. Then, it is moved from between the guide walls 63 and 64 to a region where there is no second guide wall 64. As a result, the first seal block 37 advances to the seal preparation position via the slide shaft 45 as shown in FIGS. In this state, the clamping pieces 59a and 59b of the clamping member 58 are opened, and the second seal block 38 is rotated to the retracted position around the rotation shaft 54a together with the auxiliary plate 54 by the biasing 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 conveyance path of the wrapping paper 18. Therefore, the lower hopper 33 can be positioned at the center of the transport path, and the wrapping paper 18 can be inflated on both sides thereof. For this reason, as compared with the conventional case where only one side of the wrapping paper 18 is inflated, the positional displacement of the wrapping paper 18 is less likely to occur, and even when the amount of the medicine is large, it can be appropriately accommodated.

  Here, the second cam motor 41a is driven to rotate the second cam member 41. Thereby, since the curvature radius of the outer peripheral surface of the trunk | drum 67 changes, the 2nd cam member 41 presses the 2nd bearing 47 in a center part, and is predetermined time (for example, 0.5 second) via the slide shaft 45. ), The state where the first seal block 37 is advanced to the seal position as shown in FIG. As the slide shaft 45 moves, the arm 49 provided on the flange 45a moves forward, and the first pressing portion 50 presses the pressing receiving portion 62 of the clamping member 58. Thereby, each clamping piece 59 of the clamping member 58 approaches, and the packaging paper 18 is clamped. The second pressing portion 51 presses the auxiliary block 57 via the rod 57 b 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 seal position as shown in FIG. As a result, the wrapping paper 18 is sandwiched between the heat seal portions 43 and 52 of the seal blocks 37 and 38 at the obliquely lower side portion of the lower hopper 33 located in the folded wrapping paper 18, and is substantially T-shaped, that is, The area between two adjacent packets and the area slightly over half of the side edges are sealed. On the other hand, the side portion located obliquely above the lower hopper 33 is clamped along the lower hopper 33 by the clamping member 58. Thereby, the powder supply area | region which can supply the powder for one package via the lower side hopper 33 is ensured.

  In this state, powder is supplied from the first disk 5 or the second disk 6 one by one by the scraping device 8 based on the prescription data. The supplied powder is once accommodated in the powder passage 32b of the upper hopper 32 closed by the opening / closing plate 34, and after the powder is prevented from being scattered, the opening / closing plate 34 is opened, as described above. Is supplied into the powder supply area of the wrapping paper 18 formed in this way. In the powder supply region, as described above, one side portion of the lower hopper 33 is sealed, and the other side portion is held by the holding member 58. Therefore, the supplied powder is prevented from being scattered around.

  Each time the supply of powder to the powder 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 into one package. Only carry. 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 in which the clamping state by the clamping member 58 is released. The Thereafter, powder packaging is continued according to the prescription data by the same operation as described above.

  When the packaging process is not performed, the first cam member 40 is rotated to the position shown in FIG. 16 by driving the first cam motor 40a in the packaging unit. 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 away from the wrapping paper 18 and the packaging process is not performed, it is possible to eliminate the adverse effect on the wrapping paper 18 and the medicine by the high temperature first heat seal portion 43.

  When the disk or the like needs to be cleaned, the door 9 is opened and the powder supply devices 7a and 7b are rotated, so that the intermediate plate 16 is unlocked. By the rotation of the powder supply devices 7a and 7b for supplying the powder on the first disk 5, the cleaning in the region where the powder is most likely to be scattered is facilitated. When the table 4 is pulled forward, the gear portion 16b provided on the rotating shaft of the first disk 5 meshes with the rack 10a provided on the guide rail 10 as shown in FIGS. In conjunction with this, the intermediate plate 16 rotates around the rotation axis. Along with this, the second disk 6 on the intermediate plate 16 turns around 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. Moreover, since the 2nd disk 6 is also located ahead by pulling out the table 4, and the overlapping state with the 1st disk 5 is also cancelled | released, it is easy to clean.
