<Overall configuration of packaging device>
FIG. 1 is a schematic diagram showing an example of the overall configuration of the packaging device 9. As shown in FIG. The packaging device 9 includes a container 1 , a reservoir 2 , a first measuring device 31 , a second measuring device 32 , a first control device 41 , a second control device 42 , and an enclosing device 5 .

The container 1 is a container that stores a medicine, and stores a delivery member 11 at the bottom of the space where the medicine is stored. This carrying-out member 11 is a member that carries out the medicine contained in the container 1 to the outside. That is, this container 1 accommodates a medicine and a delivery member for transporting the medicine to the outside. The discharged medicine is supplied to the reservoir 2.

The reservoir 2 is a container that temporarily stores the drug carried out from the container 1 by the carrying out member 11. That is, this storage container 2 temporarily stores the drug taken out from the container containing the drug.

The first measuring device 31 is a measuring device that measures the amount of drug stored in the reservoir 2, and is, for example, a strain gauge type, a spring type, a piezoelectric element type, a magnetostrictive type, a capacitance type, a gyro type, etc. There are various types of load cells. This first measuring device 31 is an example of a measuring device that measures the amount of medicine stored in the reservoir 2.

The first control device 41 is a device that causes the delivery member 11 to transport the medicine based on the measured amount of the medicine.

When the amount of the drug measured by the first measuring device 31 reaches a predetermined amount, the enclosing device 5 stores the drug discharged from the reservoir 2 in a packaging film and into a packaging bag (hereinafter simply referred to as a "bag"). It is a device that forms and encapsulates That is, the enclosing device 5 encloses the drug discharged from the reservoir 2 and placed in the sachet film.

Further, the second measuring device 32 shown in FIG. 1 is a measuring device that supports the container 1 and measures the weight of the stored drug and the carrying-out member 11, and is, for example, a load cell. This second measuring device 32 measures the weight of the container 1 before and after the drug is carried out by the carrying-out member 11, and measures the amount of the drug carried out based on the difference between the measured weights.

For example, the first control device 41 shown in FIG. When this happens, control is performed to reduce the speed of drug delivery. That is, the first control device 41 causes the delivery member 11 to transport the medicine at a speed corresponding to the ratio of the amount of medicine measured by the second measuring device 32 to the predetermined amount. Thereby, the first control device 41 can bring the amount of medicine to be delivered by the delivery member 11 close to the above-mentioned predetermined amount.

The second control device 42 controls the operation of the enclosing device 5, which will be described later. The second control device 42 is a computer equipped with a CPU, a memory, and an input/output interface, and is capable of inputting signals from the first measuring device 31, the reservoir 2, etc., and outputting control signals to each part in the enclosing device 5. Control is performed to form a sachet for enclosing the drug contained in the sachet film. The second control device 42 may be installed in the packaging device 9, but may also be installed in the enclosing device 5, for example.

<Container configuration>
FIG. 2 is a diagram showing an example of the configuration of the container 1. The container 1 shown in FIG. 2 has a reception port 10, a discharge member 11, and a discharge port 12. The receiving port 10 is an opening provided in the upper part of the container 1, and receives the medicine introduced along the arrow D1 shown in FIG. The medicine received from the receiving port 10 is stored inside the container 1 .

The carry-out member 11 is disposed at the bottom of the container 1 and moves surrounding medicine to carry it out from the carry-out port 12. The area Ro shown in FIG. 2 is an area closer to the outlet 12 in the area where the carry-out member 11 is installed.

The carry-out member 11 shown in FIG. 2 is driven without contacting the first control device 41 by a magnetic force generated by an electromagnet or the like included in the first control device 41.

The discharge port 12 is an opening facing downward for carrying out the drug to the outside by the action of the discharge member 11. The drug falls and is carried out from the outlet 12 to the outside of the container 1 along the arrow D2 shown in FIG.

The second measuring device 32 shown in FIG. 2 measures the weight of the container 1. Note that in the case shown in FIG. 2, the first control device 41 and the container 1 are not in contact with each other, so the second measuring device 32 is not subjected to a load by the first control device 41.

<Configuration of unloading parts>
FIG. 3 is a diagram showing an example of the configuration of the carrying-out member 11. The carrying out member 11 shown in FIG. 3 is a so-called screw, and has a shaft 110 and blades 111.

The shaft 110 is installed substantially horizontally at the bottom of the container 1, or inclined so as to descend as it approaches the outlet 12, and is supported by bearings at both ends, for example.

A magnetic body or the like that receives the magnetic force generated by the first control device 41 is attached to at least one of the ends of the shaft 110 .

The blade 111 is a member spirally provided around the shaft 110. When the shaft 110 rotates, the blade 111 pushes the surrounding medicine toward the outlet 12 and moves it along the arrow D3 shown in FIG. 3.

The first control device 41 rotates a magnetic field generated by an electromagnet or the like to rotate a shaft 110 having a magnetic material or the like, thereby driving the unloading member 11 . Thereby, the blades 111 of the carrying-out member 11 carry out the surrounding medicine stored in the bottom of the container 1 from the carrying-out port 12. That is, the first control device 41 controls the delivery member 11 to carry out the drug using magnetic force.

That is, the carrying out member 11 is a screw having a shaft 110 and blades 111 spirally provided around the shaft 110, and as the shaft 110 is rotated by the first control device 41, the container 1 A blade 111 carries out the drug from an outlet 12 provided at the bottom of the container.

Note that the distance Pt between the blades 111 that circle around the shaft 110 along the arrow D3 is such that the blades 111 in the area Ro, which is the side closer to the export port 12, are smaller in the unloading member 11 shown in FIG. It is shorter than the other side, that is, the side far from the exit 12. That is, in this carrying-out member 11, the interval between the blades is shorter on the side closer to the carrying-out port than on the side farther from the carrying-out port.

When adopting this configuration, the closer the delivery member 11 is to the delivery port 12, the shorter the interval Pt. Therefore, the amount of medicine delivered during one revolution of the shaft 110 is smaller than when the interval Pt is longer than this. It becomes a small amount. Therefore, it is possible to easily adjust the amount of the drug to be discharged from the discharge port 12.

In addition, since the interval Pt on the side far from the outlet 12 is longer than that on the side closer to the outlet 12, the speed of moving or stirring the medicine is improved compared to when the interval Pt is the same as the outlet 12. This has the effect of making it difficult for the drug to become compacted and harden.

<Storage vessel configuration>
FIG. 4 is a diagram showing an example of the configuration of the reservoir 2 in which medicine is stored. FIG. 5 is a diagram showing an example of the configuration of the reservoir 2 in a state in which the drug has been discharged.

As shown in FIG. 4, the reservoir 2 has an inlet 20, a valve 21, an outlet 22, and an opening/closing cylinder 23. The receiving port 20 is an opening provided in the upper part of the reservoir 2 . This receiving port 20 is arranged directly below the export port 12 of the container 1 . Therefore, the drug discharged from the discharge port 12 falls along the arrow D4 shown in FIG. 4 and is stored in the reservoir 2.

The valve 21 is called an opening/closing damper, a shutter, or the like, and is moved by the opening/closing cylinder 23 according to the amount of medicine stored in the reservoir 2. The outlet 22 is an opening provided at the bottom of the reservoir 2 . Since the valve 21 in the state shown in FIG. 4 closes the discharge port 22, the drug does not fall downward from the discharge port 22 and is stored inside the reservoir 2.

The valve 21 has a support shaft 210 and an elongated hole 211. The support shaft 210 is a shaft that rotatably supports the main body of the valve 21 over a predetermined range of angles. The elongated hole 211 is a hole provided in the main body of the valve 21 to engage with the opening/closing cylinder 23.

The opening/closing cylinder 23 is a rod-shaped member that expands and contracts according to the measurement results of the first measuring device 31 . The opening/closing cylinder 23 shown in FIG. 4 is, for example, a solenoid, and has a cylindrical portion 231, a cylindrical portion 232, and a pin 230.

The cylindrical portion 231 has, for example, a coil (not shown), and this coil generates a magnetic field. The cylindrical portion 232 is a plunger that is drawn into the inside of the cylindrical portion 231 by the magnetic field generated by the coil.

The pin 230 is attached to the end of the cylindrical portion 232 on the opposite side to the cylindrical portion 231 . This pin 230 is a clasp or the like passed through the elongated hole 211 of the valve 21 described above, and transmits force to the main body of the valve 21 while moving inside the elongated hole 211 according to its movement.

The first measuring device 31 is a measuring device that measures the entire weight of the reservoir 2, including the medicine stored therein.

The first measuring device 31 measures the weight of the drug stored inside the reservoir 2 by subtracting a predetermined empty weight of the reservoir 2 from the measured weight of the reservoir 2 containing the drug. . The empty weight of the reservoir 2 is the weight of the reservoir 2 with nothing inside. That is, the first measuring device 31 measures the amount of drug stored in the reservoir 2 by subtracting the empty weight of the reservoir 2 from the weight of the reservoir 2 .

The first measuring device 31 drives the opening/closing cylinder 23 when the measured weight of the medicine reaches a predetermined amount determined to be sealed in one bag. At this time, a magnetic field is generated in the coil of the cylindrical portion 231 of the opening/closing cylinder 23, and the cylindrical portion 232 is accommodated in the cylindrical portion 231, so that the total length of the opening/closing cylinder 23 is reduced. As a result, the pin 230 approaches the cylindrical portion 231, and the valve 21 rotates around the support shaft 210.

When the valve 21 rotates about the support shaft 210 along the arrow Do shown in FIG. 5, the valve 21 separates from the discharge port 22. As a result, the discharge port 22 opens downward, and the drug stored in the reservoir 2 falls downward from the discharge port 22 along arrow D5 shown in FIG. 5 and is discharged from the reservoir 2.

That is, when the amount of the drug measured by the first measuring device 31 reaches a predetermined amount, the reservoir 2 opens the valve 21 provided at the bottom and drops the stored drug. Drain the stored drug.

<Configuration of enclosing device>
FIG. 6 is a diagram showing an example of the configuration of the enclosing device 5. As shown in FIG. The enclosing device 5 shown in FIG. 6 includes a chute 50, a sealing device 51, a front roller 55, and a rear roller 56.

The chute 50 is a cylindrical member that guides the medicine to the bag so that it does not spread while falling. A receiving port 500, which is an opening, is provided at the top of the chute 50. This intake port 500 is arranged directly below the discharge port 22 of the reservoir 2 . An input port 501, which is an opening, is provided at the bottom of the chute 50. Therefore, the medicine carried out from the discharge port 22 falls along the arrow D6 shown in FIG. 6, passes through the receiving port 500 and the input port 501, and reaches the sachet film F.

The front roller 55 and the rear roller 56 are provided to sandwich the packaged film F from both sides, and by rotating, guide the packaged film F conveyed by the sealing device 51 and discharge it from the enclosing device 5. The packaged film F is held between the front roller 55 and the rear roller 56, and is conveyed from the rear roller 56 toward the front roller 55.

The sealing device 51 is arranged between the front roller 55 and the rear roller 56, and includes heating rollers 61A and 61B inside. Like the front roller 55 or the rear roller 56, the heating rollers 61A and 61B are provided so as to sandwich the sachet film F from both sides, and have a contact position where they contact the sachet film F and a distance away from the sachet film F. It is possible to move between locations.

The heating rollers 61A and 61B are roller-shaped, and when in contact with the packaging film F, rotate to heat the packaging film F while conveying it, and seal the packaging film F to package the packaging film F. Form a bag.

That is, the heating rollers 61A and 61B contact the packaging film F and heat the contact position with the packaging film F to seal the packaging film F to form a packaging bag, and also seal the packaging film F to form a packaging bag. This is an example of a heating member that is movable between a first position (contact position) in which it contacts the packaging film F and a second position (separated position) in which it is separated from the packaging film F.

FIG. 7 is a diagram showing the configuration of heating rollers 61A and 61B. The heating roller 61A and the heating roller 61B have the same configuration, and the heating roller 61A includes a rotating shaft 611A, a horizontal sealer 613A, a vertical sealer 614A, a support section 615A, and a conveying roller section 616A, and the heating roller 61B has a rotating shaft 611B, a horizontal sealer 613B, a vertical sealer 614B, a support section 615B, and a conveyance roller section 616B. The heating roller 61A will be described below, but the heating roller 61B and the members constituting it are also the same as the heating roller 61A.

The horizontal sealer 613A and the vertical sealer 614A each have a heat generating part (heater). The horizontal sealer 613A and the vertical sealer 614A generate heat by supplying power to the heaters of the horizontal sealer 613A and the vertical sealer 614A by a power supply unit (not shown). The horizontal sealer 613A and the vertical sealer 614A seal the packaging film F by contacting the packaging film F while generating heat.

The support column 615A has a cylindrical shape, and a horizontal sealer 613A and a conveyance roller section 616A are provided at both ends thereof. The horizontal sealer 613A and the conveyance roller section 616A also have a cylindrical shape, and their outer circumferential surfaces protrude from the outer circumferential surface of the support column 615A. A vertical sealer 614A is provided at one location in the circumferential direction of the support column 615A. The vertical sealer 614A is provided to protrude along the longitudinal direction of the support column 615A, and the height position of the outer circumferential surface is the same as that of the horizontal sealer 613A and the conveyance roller section 616A.

When the heating roller 61A is in the contact position where it contacts the packaged film F, the outer peripheral surfaces of the horizontal sealer 613A and the conveyance roller section 616A always come into contact with the packaged film F. As the rotating shaft 611A is rotated by the drive of the motor, the support column 615A, the horizontal sealer 613A, and the conveying roller section 616A also rotate, and the packaged film F in contact with the horizontal sealer 613A and the conveying roller section 616A is rotated. transported. In this state, the packaging film F is heated and sealed by the horizontal sealer 613A.

Every time the rotating shaft 611A rotates once, there is one period during which the vertical sealer 614A contacts the packaging film F. At this time, the packaged film F is heated and sealed by the vertical sealer 614A.

The heating roller 61A and the heating roller 61B are arranged at symmetrical positions with respect to the packaging film F, and operate in synchronization with each other. Therefore, when the heating roller 61A is in the contact position, the heating roller 61B is also in the contact position and rotates synchronously. When the horizontal sealer 613A of the heating roller 61A is in contact with the packaging film F, the horizontal sealer 613B of the heating roller 61B is also in contact with the packaging film F. Further, during the period in which the vertical sealer 614A is in contact with the packaging film F, the vertical sealer 614B of the heating roller 61B is also in contact with the packaging film F.

As described above, the packaged film F is sealed at the same position from both sides by the heating roller 61A and the heating roller 61B. The sachet film F is provided with a resin layer that melts when heated and fuses (also referred to as welding or thermal bonding) when pressurized so that they come into close contact with each other. The packaging film F is, for example, glassine paper, cellophane coated with a polyethylene film, PET resin, OPP bag, or the like.

As explained above, the enclosing device 5 seals the packaging film F by heating it in contact with the packaging film F to form a packaging bag, and at the same time, the enclosing device 5 contacts the packaging film F at the contact position (the first It has heating rollers 61A and 61B which are heating members that are movable between a first position) and a separated position away from the packaged film F (second position), and discharge the packaged film F from the storage device 2. This is for enclosing the medicine contained in the sachet film F.

<Structure of packaging film and formation of bags>
FIG. 8 is a diagram showing the structure of the sachet film F, and FIGS. 8(a) and 8(b) are diagrams showing a cross section intersecting the traveling direction. FIG. 8(a) is a diagram showing a cross section of the sachet film F taken along arrow V7a-V7a in FIG. FIG. 8(c) is a diagram showing the sealed packaged film F seen from the side.

As shown in FIG. 8(a), the packaging film F is bent along the center line Fc so that both left and right sides Fo face the chute 50 when viewed from the traveling direction. The resin layer of the sachet film F is provided on the inside of this fold.

The position of the packaged film F shown in FIG. 8(a) is before (that is, upstream) in the traveling direction than the rear roller 56 shown in FIG. 6, and has not passed through the heating rollers 61A and 61B. Therefore, in the packaged film F shown in FIG. 8(a), the two sides Fo are separated from each other and an opening is formed above.

FIG. 8(b) is a diagram showing a cross section of the sachet film F taken along the arrow V7b-V7b in FIG. The position of the packaged film F shown in FIG. 8(b) is further forward (that is, downstream) in the traveling direction than the front roller 55 shown in FIG. 6, and has passed through heating rollers 61A and 61B. Therefore, the packaged film F shown in FIG. 8(b) is heated and pressurized by the horizontal sealers 613A and 613B, and the adhesive portions Fh are fused to each other. As a result, the two sides Fo come into close contact with each other, and a space is created inside the folded sachet film F to seal the medicine. That is, the packaging film F shown in FIG. 8(b) forms a bag that seals the medicine.

In addition, "sealing" here means the meaning of sealing in Article 13 of the Measurement Act. In other words, this seal cannot increase or decrease the quantity of the object unless the product is placed in a container or packaged and the container or packaging or the seal attached to it is discarded. It means to do something like that.

FIG. 8(c) is a side view of the packaged film F (the state shown in FIG. 8(b)) after passing through the heating rollers 61A and 61B. In FIG. 8(c), the packaging film F includes a plurality of bags in which drugs M are sealed by an adhesive part Fh sealed by horizontal sealers 613A and 613B and an adhesive part Fv sealed by vertical sealers 614A and 614B. is formed.

When the heating rollers 61A and 61B rotate while in contact with the packaged film F, the packaged film F is conveyed and a bonded portion Fh is formed by the horizontal sealers 613A and 613B. When the heating roller rotates once, the vertical sealers 614A and 614B come into contact with the packaged film F to form a bonded portion Fv.

FIG. 9 is a diagram for explaining how a bag is formed from the sachet film F. FIG. 9 shows the sealing device 51 as viewed from the arrow V8 in FIG.

As shown in FIG. 9, the packaged film F is sandwiched between the front and rear sides of the sealing device 51 by front rollers 55A, 55B and rear rollers 56A, 56B, respectively, and the heating rollers 61A, 61B in the sealing device 51 rotate. , it is transported along arrow D8. A chute 50 is arranged upstream of the rear rollers 56A, 56B, and the medicine falls toward the sachet film F through the chute 50.

As shown in FIG. 7, the heating rollers 61A and 61B of the sealing device 51 are provided with horizontal sealers 613A and 613B and vertical sealers 614A and 614B. When the heating rollers 61A and 61B are at a separate position away from the packaging film F, when a power supply unit (not shown) flows a predetermined current to the heaters of the horizontal sealers 613A and 613B and the vertical sealers 614A and 614B, each The heater becomes hot.

With the vertical sealers 614A and 614B in positions facing the packaging film F, the heating rollers 61A and 61B move to contact positions where they contact the packaging film F. Then, the vertical sealers 614A and 614B come into contact with the packaging film F so as to sandwich the packaging film F, and by heating with the heaters of the vertical sealers 614A and 614B, the adhesive part Fv of the packaging film F in FIG. The resin layer is fused. The heating rollers 61A, 61B rotate, and when the vertical sealers 614A, 614B rotate to a position where they do not come into contact with the packaging film F, the heating rollers 61A, 61B stop rotating and move to a separated position away from the packaging film F. . As described above, the vertical sealers 614A and 614B seal the lateral direction of the packaged film F (that is, the direction intersecting the arrow D8).

In this state, the medicine M falls onto the packaging film F. The fallen medicine M is supported by the fused adhesive portion Fv. Thereafter, the heating rollers 61A and 61B move to the contact position where they come into contact with the packaged film F again. Then, the horizontal sealers 613A and 613B contact and rotate the sachet film F, and the resin layer at the adhesive portion Fh in FIG. It will be worn.

When the heating rollers 61A, 61B complete almost one rotation, the vertical sealers 614A, 614B come into contact with the packaged film F again, and the resin layer of the packaged film F at the adhesive portion Fv in FIG. 8 is fused. Then, the heating rollers 61A, 61B further rotate, and when the vertical sealers 614A, 614B rotate to a position where they do not come into contact with the packaging film F, the heating rollers 61A, 61B stop rotating and move to a separated position away from the packaging film F. and move.

When the heating rollers 61A, 61B rotate while in contact with the packaging film F as described above, the packaging film F is transported in the direction of arrow D8 by the rotation of the horizontal sealers 613A, 613B and the transport roller section 616A. That is, the heating rollers 61A and 61B have a conveyance mechanism that conveys the sachet film F along the arrow D8 direction (the longitudinal direction of the sachet film F). Further, the horizontal sealers 613A and 613B can seal the longitudinal direction of the packaged film F while the packaged film F is being conveyed.

As described above, the horizontal sealers 613A and 613B seal the packet film F in the longitudinal direction (that is, the direction along arrow D8). Further, in the above-described manner, the resin layer of the adhesive portions Fh and Fv of the packaging film F is fused, so that a bag is formed in which the medicine M is sealed inside.

Through the above-described operations, the packaging device 9 temporarily stores the medicine transported from the container 1 by the delivery member 11 in the storage container 2, and when the weight of the stored medicine reaches a predetermined amount, a valve is opened. 21 and seal the drug in the bag. Therefore, this packaging device 9 does not need to identify the weight of the medicine based on the difference in the weight of the container measured before and after the packaging.

<Configuration of sealing device>
10 and 11 are cross-sectional views showing the internal structure of the sealing device 51. FIG. 10 is a diagram showing a case where the heating rollers 61A, 61B are in a contact position where they are in contact with the packaging film F, and FIG. 11 is a diagram showing a case where the heating rollers 61A, 61B are in a separated position away from the packaging film F. It is a figure showing a case.

In FIGS. 10 and 11, the sealing device 51 has movable casings 512A and 512B inside a casing 511. The moving case 512A is provided with a heating roller 61A, and the moving case 512B is provided with a heating roller 61B.

Ball screws 63 and 64 are provided at both ends of the movable housings 512A and 512B. The ball screw 63 is engaged with one end of each of the movable casings 512A, 512B, and the ball screw 64 is engaged with the other end of each of the movable casings 512A, 512B. A pulley 68 is attached to one end of each of the ball screws 63 and 64. The two pulleys 68 are connected by a synchronizing belt 69.

The moving motor 67 has its rotating shaft connected to the ball screw 64, and can rotate the ball screw 64. When the ball screw 64 rotates, the pulley 68 attached to the ball screw 64 also rotates, and the rotation is transmitted to the other pulley 68 by the synchronization belt 69. As a result, the ball screw 63 to which the other pulley 68 is attached also rotates. That is, the ball screws 63 and 64 rotate synchronously with the rotation of the moving motor 67.

The ball screw 63 is provided with a right-hand thread 631 and a left-hand thread 632 that is a reverse thread. The right-hand screw 631 is screwed into a slide block 65A fixed to the movable case 512A, and the left-hand screw 632 is screwed into a slide block 65B fixed to the movable case 512B. Similarly, the ball screw 64 is provided with a right-hand screw 641 and a left-hand screw 642, the right-hand screw 641 is screwed into a slide block 66A fixed to the movable housing 512A, and the left-hand screw 642 is a movable screw. It is screwed into a slide block 66B fixed to the housing 512B.

The rotation shaft 611A of the heating roller 61A engages with an engagement portion provided on the movable housing 512A, and is rotatably attached to the movable housing 512A. Further, the rotation shaft 611B of the heating roller 61B engages with an engagement portion provided in the movable housing 512B, and is rotatably attached to the movable housing 512B.

A rotating shaft 611B of the heating roller 61B is connected to a rotating shaft of the transport motor 62. Therefore, when the transport motor 62 is driven, the rotation shaft 611B of the heating roller 61B rotates, and the heating roller 61B rotates. A gear 612A is attached to the rotating shaft 611A of the heating roller 61A, and a gear 612B is attached to the rotating shaft 611B of the heating roller 61B.

The two gears 612A, 612B mesh with each other when the heating rollers 61A, 61B are in the contact position where they are in contact with the sachet film F, as shown in FIG. Therefore, in this case, when the rotation shaft 611B and the gear 612B rotate due to the rotation of the transport motor 62, the gear 612A also rotates, and the heating roller 61A rotates in synchronization with the heating roller 61B.

When the heating rollers 61A, 61B are located at a distance from the packaging film F as shown in FIG. When this occurs, the ball screw 64 also rotates in the same direction, and the ball screw 63 also rotates in the same direction via the pulley 68 and synchronization belt 69. As the ball screws 63, 64 rotate in the first direction, the slide blocks 65A, 66A, which are threaded with the ball screws 63, 64, move downward in FIG. 11 (ie, in the direction toward the sachet film F). As the slide blocks 65A and 66A move, the movable housing 512A also moves downward in FIG. 11.

Furthermore, the slide blocks 65B and 66B that are threaded with the respective ball screws 63 and 64 are in the opposite direction from the slide blocks 65A and 66A because the left-hand screws 632 and 642 that are threaded thereon are reverse threaded. 11 (in the direction approaching the sachet film F). As the slide blocks 65B and 66B move, the movable housing 512B also moves upward in FIG. 11.

As described above, the heating rollers 61A and 61B as shown in FIG. It can be moved to a state where it is in a contact position where it makes contact.

Further, when the heating rollers 61A, 61B are in the contact position where they contact the sachet film F as shown in FIG. When the ball screw 64 is rotated in the "second direction"), the ball screw 64 is also rotated in the second direction, and the ball screw 63 is also rotated in the second direction via the pulley 68 and the synchronization belt 69. As the ball screws 63, 64 rotate in the second direction, the slide blocks 65A, 66A, which are screwed into the ball screws 63, 64, move upward in FIG. 10 (ie, in the direction away from the sachet film F). As the slide blocks 65A and 66A move, the movable housing 512A also moves upward in FIG. 10.

At this time, the slide blocks 65B and 66B, which are screwed into the respective ball screws 63 and 64, move downward in FIG. 10 (in the direction away from the sachet film F), which is the opposite direction to the slide blocks 65A and 66A. As the slide blocks 65B and 66B move, the movable housing 512B also moves downward in FIG. 10.

As described above, the heating rollers 61A and 61B as shown in FIG. It can be moved to a state in a remote location.

As described above, the sealing device 51 of the enclosing device 5 rotates the right-hand screw and the left-hand screw integrally to control the heating rollers 61A and 61B, which are heating members provided on both sides of the sachet film F, respectively. , is provided with a reverse screw mechanism for moving it between a contact position (first position) where it contacts the sachet film F and a separated position (second position) where it separates from the sachet film F.

<Procedure of packaging process>
FIG. 12 is a flowchart showing the packaging process. The process in FIG. 12 is performed by the CPU of the second control device 42 reading and executing a program stored in the memory. As a premise at the start of the process, it is assumed that the sealing device 51 is in a state where the heating rollers 61A and 61B are in a separated position away from the packaged film F as shown in FIG. Further, the rotational positions of the heating rollers 61A and 61B are assumed to be such that the vertical sealer 614A and the vertical sealer 614B face each other, as shown in FIG. 11.

First, the second control device 42 recognizes whether the packaging film F is set in the enclosing device 5 of the packaging device 9 (step S401). Before starting the packaging process, the tip position of the packaging film F needs to be set between the heating rollers 61A and 61B of the enclosing device 5. The second control device 42 may detect that the packaging film F is set by providing a sensor or the like, or the packaging film F may be set in the sealing device 51 by the operator, and for example, It may also be detected that an operation start button provided on the packaging device 9 is pressed by the operator. The second control device 42 waits until these detections are made (step S401: No).

When it is recognized that the sachet film F has been set (step S401: Yes), the second control device 42 supplies power to the heaters of the heating rollers 61A and 61B to generate heat (step S402). . The heating rollers 61A and 61B that are now in a heat generating state are kept supplied with power and kept in a heat generating state until the packaging process for all of the set packaging films F is completed.

Subsequently, the second control device 42 rotates the moving motor 67 in the first direction, so that the heating rollers 61A and 61B are brought into contact as shown in FIG. 10 from the separated position as shown in FIG. It is moved to a position (a position where the heating rollers 61A, 61B are in contact with the packaged film F) (step S403).

When the heating rollers 61A, 61B move to the contact position where they come into contact with the sachet film F, the vertical sealers 614A, 614B contact the sachet film F and heat the sachet film F. In this state, the second control device 42 rotates the conveyance motor 62 by a small amount, thereby causing the heating rollers 61A and 61B to rotate slightly (step S404). The rotation control here is such that the vertical sealers 614A and 614B are rotated by a minute amount to the extent that they are separated from the packaged film F. Through the above operations, adhesive portions Fv are formed in the transverse direction of the packaged film F by the vertical sealers 614A and 614B.

Subsequently, the second control device 42 stops the rotation of the transport motor 62 and rotates the movement motor 67 in the second direction, so that the heating rollers 61A and 61B as shown in FIG. Control is performed to move it to a state where it is at a separate position away from (step S405).

Subsequently, the second control device 42 determines whether the medicine M has been dropped onto the sachet film F (step S406). This judgment is made by detecting whether the weight of the drug measured by the first measuring device 31 has reached a predetermined amount determined to be sealed in one bag, or by discharging the drug from the reservoir 2. This can be done by detecting whether or not an operation has been performed (whether the opening/closing cylinder 23 is driven or whether the valve 21 is opened). That is, this judgment can be detected and executed by the second control device 42 inputting a signal indicating the state from the reservoir 2, the first measuring device 31, the opening/closing cylinder 23, or the valve 21.

The second control device 42 waits until it is determined that the medicine M has been dropped onto the packaging film F (step S406: No). If it is determined that the medicine M has been dropped onto the packaging film F (step S406: Yes), the second control device 42 rotates the movement motor 67 in the first direction so that the heating rollers 61A and 61B are in the separated position. from the state to the contact position (the position where the heating rollers 61A, 61B contact the packaged film F) (step S407). In addition, when the medicine M is dropped onto the packaging film F, the dropped medicine M is supported by the formed adhesive part Fv and does not fall from the packaging film F.

Note that the second control device 42 determines whether the medicine M has been dropped onto the sachet film F based on the status from the reservoir 2, the first measuring device 31, the opening/closing cylinder 23, or the valve 21, as described above. The second control device 42 may input a signal indicating . Regardless of which signal is used, the heating rollers 61A and 61B should be placed at the contact position (the position where they come into contact with the sachet film F) after the medicine is discharged from the reservoir 2 to the sachet film F. Preferably controlled. The heating rollers 61A and 61B are moved to the contact position in consideration of the time from receiving the signal until the drug is discharged from the reservoir 2 (or the time until the drug M is dropped onto the packaging film F). What is necessary is to set the timing in advance so that the timing for moving the object up to the point can be controlled.

Since the minute rotation was performed in step S404, the rotational positions of the heating rollers 61A and 61B are such that the vertical sealer 614A and the vertical sealer 614B are not facing each other. In this state, when the heating rollers 61A, 61B move to the contact position where they contact the packaging film F, the vertical sealers 614A, 614B do not contact the packaging film F, and the horizontal sealers 613A, 613B contact the packaging film F. They come into contact.

Therefore, the horizontal sealers 613A and 613B contact the packaging film F, thereby heating the packaging film F. In this state, the second control device 42 rotates the transport motor 62 once (step S408).

Then, the packaging film F is conveyed, and the horizontal sealing process is performed from a position behind the position of the packaging film F where the vertical sealing process was performed in step S404, and the adhesive part Fh is formed in the longitudinal direction of the packaging film F. It is being formed. Thereafter, the heating rollers 61A and 61B rotate to a position where the vertical sealers 614A and 614B come into contact with the packaged film F, a vertical sealing process is performed, and an adhesive part Fv is formed in the transverse direction of the packaged film F. .

As described above, the adhesive part Fv formed by the vertical sealing process in step S404 and the adhesive parts Fh and Fv formed by the horizontal sealing process and the vertical sealing process in step S408 are shown in FIG. 8(c). One of such bags is formed and the drug M is sealed.

At the end of the process in step S408, the heating rollers 61A, 61B have rotated to the position where the vertical sealers 614A, 614B are separated from the packaged film F, similarly to the end of step S404. In this state, the second control device 42 stops the rotation of the conveyance motor 62 and rotates the movement motor 67 in the second direction to move the heating rollers 61A and 61B to a separated position away from the packaged film F. Control is performed to move the image (step S409).

The first bag is formed on the sachet film F through the processes of steps S401 to S409 as described above. Subsequently, by repeating steps S406 to S409, the next bag can be formed. The second control device 42 determines whether the processing has been completed a predetermined number of times (step S410). The number of bags formed on one sheet of packaging film is predetermined. In step S410, the second control device 42 determines whether the predetermined number of bags have been formed. If the predetermined number of bags have been formed (step S410: Yes), the second control device 42 ends the process. If the predetermined number of bags have not been formed (step S410: No), the second control device 42 returns to step S406 and repeats the process.

According to the embodiments described above, the following effects can be obtained.
(1) According to the packaging device 9 of the present embodiment, the medicine carried out from the container 1 is temporarily stored in the storage container 2, and when the amount to be enclosed in one bag is reached, the medicine is transferred from the storage container 2. Since the medicine is discharged into the sachet film F, the amount of medicine itself to be sealed in each bag can be measured.

(2) The sealing device 51 of the packaging device 9 of this embodiment moves the heating rollers 61A and 61B, which are heating members for sealing the packaging film F, to the contact position where the packaging film F contacts and the packaging film F. Since the heating rollers 61A and 61B can be moved to the separated position away from the film F, the heating rollers 61A and 61B can be retracted to the separated position while the drug is temporarily stored in the reservoir 2 and its weight is measured.

For this reason, in this packaging device 9, even if the heating rollers 61A and 61B continue to be supplied with power and are in a heat-generating state when the transport of the packaging film F is once stopped while measuring the weight, the heating rollers 61A and 61B , 61B to a separate position, it is possible to prevent the same part of the packaged film F from being heated continuously. Therefore, this packaging device 9 can prevent the packaging film F from being damaged due to overheating.

(3) The packaging device 9 of this embodiment can move the heating rollers 61A and 61B to the separated position even if the transport of the packaging film F is stopped while the drug is temporarily stored in the reservoir 2 and the weight is being measured. By evacuating the heating rollers 61A and 61B, it is possible to continue supplying power to the heating rollers 61A and 61B and keep them in a heat generating state. Therefore, this packaging device 9 does not need to use an impulse type sealer that is powered and generates heat only when it comes into contact with the packaging film F, and the configuration of the sealing device can be simplified.

<Modified example>
The above is the description of the embodiment, but the content of this embodiment can be modified as follows. Further, the following modifications may be combined.

<1>
In the embodiment described above, the storage device 2 measures the amount of the drug stored therein by the first measuring device 31, and discharges the drug to the outside when the amount reaches a predetermined amount. However, the stored medicine may be sealed in a bag in the reservoir 2 and taken out together with the bag. In this case, the enclosing device 5 may be integrated with the reservoir 2. In this case, the first measuring device 31 calculates the amount of drug stored in the bag installed in the storage device 2 by subtracting the total of the empty weight of the storage device and the empty weight of the bag from the weight of the storage device 2. All you have to do is measure it.

That is, the enclosing device 5 only needs to enclose the drug in the bag when the amount of the drug stored in the reservoir 2 and measured by the first measuring device 31 reaches a predetermined amount.

<2>
In the embodiment described above, the reservoir 2 had the valve 21 at the bottom, but the reservoir 2 may not have the valve 21. For example, the reservoir 2 may be rotated so that the receiving port 20 is directed downward when the amount of the stored drug, as measured by the first measuring device 31, reaches a predetermined amount. In this case, the medicine stored in the reservoir 2 is discharged from the receiving port 20.

<3>
In the embodiment described above, the first control device 41 controls the speed of drug delivery when the amount of decrease in weight measured by the second measuring device 32 before and after the drug delivery reaches 80% or more of the predetermined amount. Although the control was performed to lower the temperature, other controls may also be used. For example, when the weight of the drug stored in the reservoir 2, as measured by the first measuring device 31, exceeds a predetermined ratio of the predetermined amount, the first control device 41 controls the speed of drug delivery. Control may be performed to lower the value. Further, the first control device 41 may control the speed at which the medicine is carried out using a function in which the independent variable is the ratio of the weight of the medicine measured by the first measuring device 31 to the predetermined amount.

That is, the first control device 41 in this modification causes the delivery member to carry out the drug at a speed corresponding to the ratio of the amount of the drug measured by the first measuring device to the predetermined amount.

<4>
In the embodiment described above, the first control device 41 causes the dispensing member 11 to carry out the medicine by magnetic force without contacting the dispensing member 11. may have. In short, the first control device 41 does not need to use magnetic force as long as it causes the delivery member to transport the medicine based on the measured amount of medicine.

For example, the end of the shaft 110 of the unloading member 11 may extend from the housing of the container 1 to the first control device 41. In this case, the first control device 41 may rotatably support the end of the shaft 110 and transmit power from this end to rotate the unloading member 11 . In this case, the second measuring device 32 may measure the weight of the container 1 and the first control device 41.

<5>
In the embodiment described above, the delivery member 11 is a so-called screw feeder having the shaft 110 and the blades 111, but the mechanism for delivering the medicine is not limited to this. The discharge member 11 may be, for example, a screw without a shaft, a bucket conveyor, or a belt conveyor.

Moreover, when the carrying-out member 11 is a screw, the shape of the blade|wing 111 is not restricted to what was mentioned above. For example, the blades 111 may have a uniform interval Pt between the region Ro and other regions. Further, the blade 111 may be, for example, a ribbon-shaped screw supported by a plurality of support rods extending from the shaft 110 in the region Ro. In this case, since the blade 111 in the region Ro has a gap between it and the shaft 110, the drug may move backward through this gap, and the amount of the drug to be carried out can be suppressed.

<6>
In the embodiment described above, a reverse screw mechanism is used as a mechanism for moving the heating rollers 61A, 61B of the enclosing device 5 between the contact position and the separation position, but an eccentric cam mechanism may be used.

FIG. 13 is a sectional view showing the internal structure of a sealing device according to a modified example, and is a diagram showing a case where the heating rollers 61A and 61B are in a contact position where they are in contact with the sachet film F. In FIG. 13, the sealing device 71 has movable housings 712A and 712B inside a housing 711. The moving case 712A is provided with a heating roller 61A, and the moving case 712B is provided with a heating roller 61B.

The outer circumferential surfaces of the eccentric cams 81A and 81B are respectively provided so as to be in contact with the surfaces of the movable casings 712A and 712B on the side opposite to the side where the heating rollers 61A and 61B are provided. The eccentric cam 81A and the eccentric cam 81B have rotating shafts 82A and 82B provided at eccentric positions, and the rotating shafts 82A and 82B are rotatably engaged with the inner surface of the housing 711.

A spring 83A is connected between the inner surface of the casing 711 facing the eccentric cam 81A and the surface of the movable casing 712A facing the eccentric cam 81A. It is energizing. Since the eccentric cam 81A is provided between the movable housing 712A and the inner surface of the housing 711, the movable housing 712A is in contact with the outer peripheral surface of the eccentric cam 81A and is biased.

The configuration of the housing 711, the movable housing 712A, the eccentric cam 81A, and the spring 83A as described above is the same for the housing 711, the movable housing 712B, the eccentric cam 81B, and the spring 83B. The eccentric cam 81B is in contact with the outer circumferential surface of the eccentric cam 81B and is biased.

A rotating shaft 82B of the eccentric cam 81B is connected to a rotating shaft of a moving motor 85. A pulley 86A is attached to the rotating shaft 82A of the eccentric cam 81A, and a pulley 86B is attached to the rotating shaft 82B of the eccentric cam 81B. Pulley 86A and pulley 86B are connected by a synchronizing belt 87.

As shown in FIG. 13, when the moving motor 85 is rotated when the heating rollers 61A and 61B are in the contact position where they are in contact with the packaging film F (the rotation direction may be either direction), the rotating shaft 82B, the eccentric cam 81B, Pulley 86B also rotates. Then, the pulley 86A connected to the pulley 86B by the synchronization belt 87 also rotates, and the rotating shaft 82A and eccentric cam 81A also rotate.

By rotating the eccentric cam 81A. The outer peripheral surface of the eccentric cam 81A that is in contact with the moving housing 712A moves upward in FIG. 13. At this time, the outer circumferential surface of the eccentric cam 81A moves in a direction away from the outer circumferential surface of the movable casing 712A, but the outer circumferential surface of the movable casing 712A is in contact with the outer circumferential surface of the eccentric cam 81A due to the biasing force of the spring 83A. is maintained, and the movable housing 712A moves upward in FIG. As a result, the heating roller 61A, which was in the contact position where it contacts the packaged film F, moves upward in FIG. 13, that is, to a separated position away from the packaged film F.

Similarly, as the eccentric cam 81B rotates, the outer peripheral surface of the eccentric cam 81B that is in contact with the movable housing 712B moves downward in FIG. 13, and the movable housing 712B moves downward in FIG. . At this time, the outer circumferential surface of the eccentric cam 81B moves in a direction away from the outer circumferential surface of the movable casing 712B, but the outer circumferential surface of the movable casing 712B is in contact with the outer circumferential surface of the eccentric cam 81B due to the biasing force of the spring 83B. is maintained. As a result, the heating roller 61B, which was in the contact position where it contacts the packaged film F, moves downward in FIG. 13, that is, to a separated position away from the packaged film F.

When the moving motor 85 is rotated when the heating rollers 61A, 61B are at a separate position away from the packaging film F, the eccentric cams 81A, 81B rotate and are in contact with the moving housing 712A of the eccentric cam 81A. The outer circumferential surface moves downward in FIG. 13, and the outer circumferential surface of the eccentric cam 81B that is in contact with the moving housing 712B moves upward in FIG. 13. As a result, the heating rollers 61A and 61B move to the contact position where they come into contact with the sachet film F.

As described above, by rotating the moving motor 85 and moving the movable casings 712A and 712B, the heating rollers 61A and 61B are moved from the contact position where they contact the sachet film F to the sachet film F. It can be moved between remote locations.

The heating rollers 61A and 61B may be controlled in the same manner as in the above-described embodiment, and by using the sealing device 71 of FIG. 13 and controlling the conveying motor 62 and the moving motor 85 by the second control device 42, Similar to the embodiment described above, a bag can be formed in the sachet film F and the medicine can be sealed therein.

<7>
In the embodiment described above, when the amount of the drug measured by the first measuring device 31 reaches a predetermined amount, the valve 21 provided at the bottom is opened and the stored drug is dropped. Although it is assumed that the storage device 2 performs this operation, the second control device 42 may also perform the operation. In this case, the packaging device 9 may have a configuration that allows the second control device 42 to control the acquisition of measurement data from the first measuring device 31 and the output of the control signal to the reservoir 2 as described above. .

<8>
In the embodiment described above, the first control device 41 controls the delivery member 11 to carry out the medicine, and the second control device controls the sealing device 51. It may also be performed by a control device.

<9>
In the above-described embodiment, the medicine taken out from the container 1 containing the medicine is temporarily stored in the reservoir 2, and then the stored medicine is discharged to the sachet film F. However, the configuration for carrying out the process from accommodating to discharging the medicine is not limited to this.

For example, if the package film F can be configured to discharge a predetermined amount of medicine, there is no need to provide the reservoir 2. In short, when a predetermined amount of medicine is discharged onto the sachet film F by some kind of discharge mechanism, if the second control device 42 can recognize the timing of discharge (for example, if a signal indicating the timing is input If possible), a configuration other than the configuration of the above-described embodiment may be used.

<10>
In the above-described embodiment, there is only one path for discharging the medicine from the packaging film F (for example, the path from the container 1 to the chute 50, or a part of that path). , there may be more than one route for expelling the drug. The drug may be a powder, a tablet, or a combination thereof. For example, if there are two routes, one route may be for discharging powders to the packaging film F, and the other route may be for discharging tablets to the packaging film F. When the drug is a tablet, the amount of tablets to be discharged onto the packaging film F may be specified by the number of tablets rather than by weight. The heating rollers 61A and 61B, which are heating members, may be moved to the contact position (first position) when the second control device determines that the medicine for the sachet film F has been discharged through all routes. .
