Description

  The present invention relates to a medicine packaging device that is incorporated into a medicine packaging machine or used alone for packaging various medicines such as tablets and powders, and more specifically, intermittently feeds a long sachet for use in medicine packaging. The present invention relates to a drug packaging device that puts a drug into it while sorting and seals it.

  A drug packaging device that sequentially feeds a long bandage in the longitudinal direction and wraps a drug, for example, collects and drops a drug discharged from a drug feeder, a drug distribution and division mechanism, etc. In many cases, it is housed in a low-casing housing, but it is equipped with a banding band supply mechanism, a printing mechanism, and a division sealing mechanism that are arranged in order from upstream to downstream along the banding band feeding path (for example, patents). Reference 1-7). Each of these mechanisms is mounted on one side of a substrate (base plate) to which the medicine is dropped, and in the vertical type, the substrate is fixed vertically (see, for example, Patent Document 4). On the other hand, in the horizontal type, the substrate is held horizontally, and each mechanism is attached to the upper surface thereof, and the substrate can be pulled out for the purpose of exchanging the bandage roll or the like (for example, Patent Document 7). reference).

  In addition, among the mechanisms, the bandage supplying mechanism holds the roll of the bandage and feeds the bandage in order from the tip while gradually unwinding the winding, in order to adjust the tension applied to the bandage With a tension adjustment mechanism. Conventionally (see, for example, Patent Documents 4 and 5), the tension adjustment mechanism is realized by swinging the movable roller with an arm or urging the arm with a spring, etc., and imparting an appropriate tension to the bandage. In addition, the loosening state of the bandage was adjusted so as not to cause inconvenient slack.

Furthermore, in the medicine packaging apparatus provided with the ink ribbon feeding mechanism for medicine bandage printing that sends the ink ribbon to the print head facing the bandage sent to the medicine loading position, the ink ribbon feeding mechanism for medicine bandage printing is the print head. Some are divided into a main body portion on the side and a cover portion that can be attached to and detached from the main body portion (see, for example, Patent Document 7).
In this conventional apparatus, an operation portion of a head advance / retreat mechanism for advancing and retracting the print head toward the bandage is provided on the cover portion. The box-shaped part of the cover was made of metal and opaque. Further, the attached cover portion could not be locked.

Compared with the vertical type and the horizontal type on the premise that the dividing band supply mechanism, the printing mechanism, and the sorting and enclosing mechanism are arranged in a plane for such a conventional medicine packaging device, the vertical type makes it easy to replace the banding roll. It is easy to install in a high position and occupies a small area, but the folding bandage roll cannot be used, whereas the horizontal type can use the folding bandage roll, but the occupation area is wide and the banding roll position is low. It tends to be.
Therefore, it is a first technical problem to realize a medicine packaging apparatus that can use a roll of two-fold bandages and that can be easily replaced and requires only a small area.

Further, in the case of the conventional medicine packaging apparatus described above, in which the tension adjusting mechanism using the movable roller is attached to the packing band supply mechanism, the packing band is fed at high speed in order to improve the packing speed. As a result, the moving range of the movable roller widens and eventually exceeds the allowable range. However, if the movement range of the movable roller is restricted by a simple stopper or the like, the inertial movement of the bandage roll or the like cannot be stopped smoothly, so it cannot absorb undesired relaxation of the bandage. .
Therefore, a second technical problem is to realize a medicine packaging device that can accurately regulate the movement of the movable roller that adjusts the tension of the bandage.

Further, in the case of the conventional medicine packaging apparatus described above, in which the ink ribbon feeding mechanism for medicine bandage printing is divided into the main body part and the cover part, the operation of the head advancing / retreating mechanism for advancing and retreating the print head toward the packaging band Since the cover portion was provided on the cover portion, the cover portion was heavy by that amount, so that a force corresponding to the cover weight was required when the cover was attached or detached.
Therefore, it is a third technical problem to realize a medicine packaging device in which the cover part of the ink ribbon feeding mechanism for medicine bandage printing is light and easy to attach and detach.

Further, in the case of the conventional medicine packaging device described above, in which the ink ribbon feeding mechanism for medicine bandage printing is divided into the main body portion and the cover portion, the box-shaped portion of the cover portion is made of metal and opaque. Even if there was a malfunction in the operating state of the internal mechanism covered with the cover, it could not be easily confirmed visually. Moreover, since the cover part was heavy, the force corresponding to it was required for attachment or detachment of the cover.
Therefore, it is a fourth technical problem to realize a medicine packaging device that is light and easy to attach and detach and that can easily recognize the operating state of the ink ribbon feeding mechanism for medicine bandage printing.

In addition, in the case of the conventional medicine packaging device described above, in which the ink ribbon feeding mechanism for medicine bandage printing is divided into the main body part and the cover part, the attached cover part cannot be locked. When the substrate and the mounting device are pulled out for the purpose, care must be taken to avoid inadvertent contact with the cover part during cleaning work so that the cover part does not undesirably come off.
Therefore, it is a fifth technical problem to realize a medicine packaging device that can be attached / detached when the cover of the ink ribbon feeding mechanism for medicine bandage printing can be attached / detached but cannot be removed otherwise.

  The medicine packaging apparatus of the present invention (Solution means 1) was devised to solve such a problem, and is a mechanism for feeding a long bandage in a progressive manner while releasing a bandage roll. The mechanism, the printing mechanism that prints information such as the drug name and usage on the bandage, and the division enclosure that is the mechanism that separates the bandage by performing vertical seal and horizontal seal and puts the medicine into each compartment In a medicine packaging apparatus in which a mechanism is disposed on the upper surface of a substrate from which a medicine can be dropped along a packaging band feeding path, the substrate is inclined with the installation side of the packaging band supply mechanism raised. It is characterized by that.

  Further, the medicine packaging apparatus of the present invention (Solution means 2) is the medicine packaging apparatus of the above solution means 1, wherein the section enclosing mechanism includes a pressing member, a medicine charging hopper, and a sealing mechanism, The presser member is erected upstream of the medicine charging hopper and regulates swinging with a wrapping band interposed therebetween, and the seal mechanism has both a horizontal seal portion and a vertical seal portion positioned downstream of the medicine charging hopper. It is characterized by.

  Furthermore, the medicine packaging apparatus of the present invention (Solution means 3) is characterized in that a damper is provided in the moving range of the movable roller for adjusting the tension of the dividing band.

  Further, the medicine packaging apparatus of the present invention (Solution means 4) includes an ink ribbon feeding mechanism for printing a medicine bandage for feeding an ink ribbon to a print head facing a bandage sent to a medicine charging position, and a main body portion on the print head side. In the medicine packaging device divided into a cover part that can be attached to and detached from it, a head advancement / retraction mechanism for advancing and retreating the print head toward the packing band and an operation part thereof are provided in the main body part, and a hole through which the operation part can be inserted is provided. The cover portion is formed so as to penetrate therethrough.

  Further, the medicine packaging device of the present invention (Solution means 5) is provided with an ink ribbon feeding mechanism for medicine bandage printing for feeding an ink ribbon to a print head facing a bandage fed to a medicine charging position, and a main body portion on the print head side. In the medicine packaging apparatus divided into a cover part that can be attached to and detached from the cover part, a box-shaped part of the cover part is made of a transparent resin or a translucent resin.

  Further, the medicine packaging apparatus of the present invention (Solution means 6) is provided with an ink ribbon feeding mechanism for printing a medicine bandage for feeding an ink ribbon to a print head facing a bandage fed to a medicine loading position, and a main body portion on the print head side.

  In such a medicine packaging apparatus of the present invention (Solution 1), the dividing band supply mechanism, the printing mechanism, and the division enclosing mechanism necessary for sorting and packaging the medicine with the long dividing band can be pulled out. Since it is arranged in a plane on the upper surface of a simple substrate, the horizontal advantage of being able to use a roll of bi-fold bandage is inherited. Nevertheless, since the board is tilted, the occupied area is reduced by being a projected component on the floor surface, so it is sufficient to be smaller than the area of the upper surface of the board, so it is less than the conventional horizontal floor area. As a result, the apparatus casing can be made slim.

Moreover, when the substrate is pulled out for replacing the bandage roll by raising the installation side of the bandage supply mechanism when tilting the substrate, the position of the bandage supply mechanism to which the bandage roll is attached is more than that of the conventional horizontal type. Since it is high, it is easy to change the bandage roll.
Therefore, according to the present invention, it is possible to realize a medicine packaging device that can use a roll of two-fold bandage and that can be easily exchanged and requires only a small area, thereby solving the first technical problem. Is done.

  Further, in the medicine packaging apparatus of the present invention (solution 2), the conventional horizontal type is positioned upstream of the medicine charging hopper by utilizing the fact that the dividing band feeding path is also inclined as the substrate is inclined. Since the vertical seal was moved downstream of the drug charging hopper, the horizontal seal also came to the vertical seal that was originally positioned downstream of the drug charging hopper, and the seal mechanism was integrated. In addition, the classification and encapsulation mechanism including the control system and the control system are simplified, and the miniaturization contributing to the reduction of the occupied area and the reduction of the cost can be achieved at the same time.

In addition, it is sufficient to provide a simple and inexpensive presser member upstream of the medicine injection hopper that has no vertical seal, and the presser member is erected and regulates the vibration with the bandage in between. When replacing the bandage roll, it is easy to perform the work of inserting the bandage into the bandage feed path from above and stretching it.
Therefore, according to the present invention, it is possible to realize a medicine packaging device that can use a roll of two-fold bandage, can easily replace the bandage roll, occupies less area, and is less expensive. One technical problem is solved to a high degree.

  Furthermore, in the medicine packaging device of the present invention (solution 3), since the damper is provided in the movable range of the movable roller, when the movable roller stops moving due to the restriction, the movable roller suddenly stops. Rather than stopping, after decelerating according to the shock absorbing characteristics of the damper. Therefore, adopt a damper that exhibits buffering characteristics suitable for the inertial movement of the bandage roll, etc., or adjust the buffering characteristics to adjust the inertial movement of the bandage roll etc. Accordingly, the movement of the movable roller can be accurately regulated.

That is, even if the feeding speed of the packing band is increased, the movable roller moves within the allowable range, and the inertial movement of the packing band roll and the like stops smoothly together with the movable roller, so that the banding band relaxes undesirably. There is nothing.
Therefore, according to the present invention, it is possible to realize a medicine packaging device that can accurately regulate the movement of the movable roller that adjusts the tension of the packing band, and the second technical problem is solved.

In the medicine packaging device of the present invention (solution 4), since the operation unit that has been conventionally provided in the cover unit is moved to the main body unit, the cover unit is lightened by the amount of the operation unit. Yes. In addition, since the insertion hole of the operation portion is formed through the cover portion, the cover portion is further lightened.
Therefore, according to the present invention, it is possible to realize a medicine packaging device in which the cover portion of the ink ribbon feeding mechanism for medicine bandage printing is light and easy to attach and detach, and the third technical problem is solved.

Moreover, in the medicine packaging device of the present invention (solution 5), the cover portion is light because the box-shaped portion of the cover portion is made of resin instead of metal. In addition, since the box-shaped portion of the cover portion is not opaque and is transparent or translucent, it is possible to visually confirm the operating state of the internal mechanism from the outside even if it is covered with the cover.
Therefore, according to the present invention, it is possible to realize a medicine packaging device in which the cover portion is light and easy to attach and detach, and the operation state of the ink ribbon feeding mechanism for medicine bandage printing can be easily visually recognized. Solved.

In the medicine packaging device of the present invention (solution 6), a key portion is provided so that the cover portion is not undesirably removed, and the cover portion can be locked. Since the locking / unlocking is performed in conjunction with the operation of the head advancing / retreating mechanism, the lock is maintained in a printing state where it is not desirable to remove the cover, whereas the print head is separated from the bandage. When the printing posture is released, unlocking is also performed accordingly, and the cover portion can be attached and detached.
Therefore, according to the present invention, it is possible to realize a medicine packaging device that can be attached / detached when the cover of the ink ribbon feeding mechanism for medicine bandage printing can be attached / detached but cannot be removed otherwise. The problem is solved.

Since it is sufficient to pass the bandage 8 between them (see FIGS. 1D and 1E), the bandage 8 is inserted into the bandage feed path from above. Can be easily set.

  In order to replenish and replace the ink ribbon 71, it is preferable that the ink ribbon roll 70 is mounted in advance using the spare ink ribbon feed mechanism cover 60. When the ink ribbon 71 is attached to the ink ribbon feeding mechanism cover 60 (see FIG. 2B), the ink ribbon feeding mechanism cover 60 is turned upside down, that is, the release surface of the ink ribbon cover 64 is faced up. The ribbon take-up tube 72 is fitted on the ink ribbon take-up mechanism outer fitting portion 69, and the ink ribbon roll 70 is fitted on the ink ribbon supply mechanism outer fitting portion 61. Then, the tip of the ink ribbon 71 is attached. The ink ribbon is drawn out from the ink ribbon roll 70 and wound around the ribbon take-up pipe 72 in order around the outside of the ink ribbon guide mechanisms 62, 63, 66 and 68.

  When it becomes necessary to replenish the medicine packaging device 20 with the ink ribbon 71, the ink ribbon feeding mechanism 40 + 60 to the ink ribbon feeding mechanism with the medicine packaging device 20 pulled out (see FIG. 1B). The cover part 60 is removed, and instead, a spare ink ribbon feed mechanism cover part 60 with an ink ribbon attached in advance is attached to the ink ribbon feed mechanism main body part 40. Of course, the cover 60 can be easily replaced with the ribbon attached to the cover 60 described above because the cover 60 is lighter.

  At this time, the ink ribbon feeding mechanism cover unit 60 can be easily and quickly removed in the reverse order of the mounting method described below, but the ink ribbon feeding mechanism main body 40 remains on the substrate 21 from which the cover unit 60 has been removed. In the main body 40, the print head 42 is retracted in the separation direction of the platen 41 (see FIG. 2A). In this state, the cover portion 60 on which the ink ribbon is mounted is brought on the ink ribbon feeding mechanism main body portion 40 for attachment. When the ink ribbon feed mechanism cover unit 60 is held in the hand with the cover handle 60a up, the release surface is naturally lowered. Therefore, when the ink ribbon feeding mechanism main body 40 is lowered, the ink ribbon feeding mechanism main body 40 overlaps the ink ribbon feeding mechanism cover 60 (see FIG. 2D).

  In addition, along with this, the print head advance / retreat mechanism operation unit 47 passes through the inner hole 67a of the metal plate of the ink ribbon feeding mechanism cover unit 60 and further protrudes from the outer hole 67 of the ink ribbon cover 64 to be operable. The key portion 47a passes through the key hole 67b of the metal plate of the ink ribbon feeding mechanism cover portion 60 and reaches the inner side of the ink ribbon cover 64, and the ink ribbon supply mechanism inner fitting portion 44 and the ink ribbon supply mechanism outer fitting portion 61 are fitted. The ink ribbon take-up mechanism inner fitting portion 45 and the ink ribbon take-up mechanism outer fit portion 69 are also fitted. The ink ribbon 71 enters between the platen 41 and the bandage 8 and the print head 42. Then, the detection result with the ink ribbon is notified to the controller from the ribbon presence / absence detection members 43 and 46, but the head advance / retreat detection member 49 notifies that the print head 42 is in the retracted state.

  Then (see FIG. 2E), when the print head advance / retreat mechanism operation unit 47 is operated and rotated, the print head advance / retreat mechanism operation unit 48 swings, and the print head 42 moves forward toward the platen 41. The ink ribbon 71 and the bandage 8 overlap in the narrow gap. Moreover (see FIGS. 2B and 2C), the operation of the print head advance / retreat mechanism operation section 47 causes not only the print head advance / retreat mechanism operation section 48 but also the key section 47a to swing together, so that the key section 47a becomes the key hole 67b. Since the ink ribbon feeding mechanism cover 60 is locked by the interference between the key 47a and the metal plate, the print head advancing / retreating mechanism operating portion 47 is not operated in the reverse direction. As long as the ink ribbon feeding mechanism main body 40 does not come off.

  Further, as the print head 42 advances, a notification that the print head 42 is in the forward state is sent from the head advance / retreat detection member 49 to the controller. Therefore, coupled with the fact that the presence of ink ribbon has been detected first, the controller As a result of this control, the ink ribbon take-up mechanism inner fitting portion 45 and the ink ribbon take-up mechanism outer fit portion 69 are slightly pivoted, whereby the leading portion of the ink ribbon 71 is taken up by the ribbon take-up tube 72. The slack of the ink ribbon 71 is eliminated. Then, it is possible to print on the bandage 8 by the print head 42 with the ink ribbon 71 interposed.

If the medicine packaging device 20 is replenished with the banding band 8 and the ink ribbon 71, the packaging state of the medicine packaging device 20 is adjusted. Then, the medicine packaging machine 10 is caused to automatically perform medicine packaging.
When the automatic packaging starts, the medicine is delivered to the medicine input hopper 52 of the medicine packaging device 20 from the powder dividing device 12 and the tablet handing device 13 via the medicine collecting mechanism 14 one by one, and the medicine packaging device 20 uses the medicine. Is divided and packaged in a bandage 8.

  Specifically, the operation of the division packaging is as follows. In the medicine packaging device 20, the bandage 8 is fed from the bandage roll by the bandage supply mechanism 30, and the bandage feeding mechanism 54 and the fixed roller 23 set the bandage feeding path. It is forwarded. At that time, the dividing band 8 is intermittently fed in the longitudinal direction in the length unit of the compartment storage chamber, and each time the ink ribbon feeding mechanism main body 40 has the patient name, usage, etc. In the sorting and sealing mechanism 50, the medicine for one pack is put into the portion between the pressing member 51 and the seal mechanism 53 in the packing band 8, and then the packing band 8 is intermittently fed. Then, the medicine is stored in a vertical and horizontal direction by, for example, heat sealing and sealing, and a medicine storage compartmentalized compartment (packaging) is completed.

  Such intermittent feeding, printing, medicine charging, and sealing, and perforation formation and cutting are omitted under the details, and a series of medicine packaging processing is performed under the control of the controller. Of these, the drug charging operation will be described in detail (see FIGS. 1D and 1E). The part of the dividing band 8 that comes under the drug charging hopper 52 has the same inclination angle as that of the substrate 21 and the upstream side is high. Since the downstream side is low, even if the upstream side is lightly pinched by the presser member 51 from the bottom, there is no possibility that the injected drug will enter the upstream next chamber beyond the presser member 51. Since the downstream side is divided at the time of sealing the front chamber by the sealing mechanism 53, there is no possibility that the medicine is mixed here. Therefore, even if the seal mechanism 53 comes to the downstream of the medicine charging hopper 52 together with the horizontal seal and the vertical seal, there is no inconvenience in the sealing performance, and an appropriate seal is made.

  In addition, the intermittent feeding of the bandage 8 will also be described in detail (see FIG. 1C). In the bandage supply mechanism 30, the self-propelled supply roller 32 unwinds the bandage roll and sends out the bandage band 8. A moderate braking force is applied to the bandage shaft support 31 by the brake 33 so as not to run away. Furthermore, the intermittent feeding by the bandage pulling mechanism 54 and the intermittent feeding by the self-propelled supply roller 32 have different characteristics and timing deviations, so that the tension of the bandage 8 is made as constant as possible in order to absorb the influence. Thus, the tension of the bandage 8 is adjusted by the swinging of the movable roller 36 biased by the spring 34.

  If the feeding speed of the bandaging band 8 is the same as or slower than the conventional speed, the movable range of the movable roller 36 is within an appropriate range between the rocking position B and the rocking position C, and the tension of the bandaging band 8 is also conventional. Similarly, it is maintained at an appropriate value. On the other hand, if the feeding speed of the bandage 8 is made higher than before, the inertial movement due to the inertia of each member and the banding roll also increases, so that when the feed of the self-running supply roller 32 is stopped, the movable roller 36 May reach the swinging position D beyond the swinging position B, but since the rod of the damper 35 is waiting there, the movable roller 36 is stopped by the damper 35 without impairing the tension adjusting function.

That is, the movable roller 36 does not stop suddenly, but does not go too far, and stops moderately in a decelerating state commensurate with the deterring force of the brake 33 and the like against inertial movement such as a bandage roll.
Therefore, even if the characteristics of the brake 33 and the spring 34 are maintained in the same manner as before in order to keep the tension of the bandage 8 at an appropriate value, the feeding speed of the bandage 8 and the packaging speed of the medicine packaging device 20 and further the medicine The packaging speed of the packaging machine 10 can be increased without any inconvenience.

  The medicine packaging apparatus of the present invention is not limited to the medicine packaging machine 10 described above, but may be incorporated into a tablet packaging machine equipped with a large number of tablet feeders, or may be incorporated into a so-called V-shaped powder medicine packaging machine, or as a single unit.
