Description

  The present invention relates to a drug bagging machine that packs drugs contained in containers such as ampoules, bottles, PTPs, boxes, etc. into a drug bag, and more particularly, to a drug loading mechanism that loads a drug into the drug bag from its mouth.

  In the conventional drug bagging machine, the drug to be packed is dropped at the drug loading position by the drug loading mechanism, and the drug bag is held by the drug bag holding mechanism with the mouth opened in advance below the drug loading position. The medicine was automatically packed in the bag. The medicine input mechanism is configured to inject all the medicines in the tray all at once by tilting the tray when collecting or carrying in the medicine to be supplied is performed using the tray. On the other hand, when collection and delivery of the medicines to be introduced are performed by direct conveyance by a conveyance mechanism such as a belt conveyor, the drugs are separately introduced every time they are conveyed.

Of course, even in the case of direct conveyance on a belt conveyor, etc., in the drug input mechanism in which a shutter is attached to the end of the transfer path and the stored drug is temporarily stored, the stored drug is input all at once by opening the shutter. Is done.
In any case, the belt conveyor in the medicine feeding mechanism, that is, the belt conveyor that transports the collected medicines and trays and reaches the medicine feeding position is a single wire or a single wire (for example, see Patent Document 1). .
JP 2001-212208 A (Page 5, FIG. 4)

[Unpublished Patent Application 1] Japanese Patent Application No. 2002-319403 By the way, since the medicine bagging machine as described above automatically performs bagging, in addition to the advantage of high processing efficiency, it is also possible to pack the bag. There is also an advantage that a human hand does not need to touch the medicine directly after that. In particular, if the medicine bag is made transparent, it is possible to perform an audit without opening the medicine bag, so it is possible to eliminate almost direct contact between the medicine and the hand at the time of application. From the viewpoint, a transparent medicine bag delivery method using a medicine bagging machine is attracting attention.

  However, in the case of conventional medicine bagging machines, not only when the medicines are charged in bulk, but also when the medicines are charged together, the charging is slow over time so that the drugs do not collide and the drug container is broken by the impact. Had to be done. Also, if a bottle or the like falls and collides with an easily breakable part such as the neck of an ampoule, it is easy to damage even if it is slowly put in, so it was necessary to avoid packing such drugs together. For this reason, the use of drug bagging machines has been limited.

Therefore, in order to fully support the practical use of the transparent medicine bag delivery method, even if the medicine is put into the medicine bag in a shorter time and more efficiently than before, various medicines such as ampoules and small bottles are combined and packed together. Even so, it is a basic technical problem to devise a medicine injection mechanism so that the medicine can be gently packed without damaging the medicine container.
And in order to solve such a subject, the medicine bagging machine which can carry out the medicine injection | pouring into a medicine bag gently and quickly by the same applicant is developed (refer unpublished patent application 1).

  In the drug bagging machine provided with a drug bag holding mechanism that opens the mouth by holding the drug bag at or below the drug charging position and a transport mechanism that transports the drug to the drug charging position and drops it, The transport mechanism is horizontally provided with a first belt conveyor unit that travels from the medicine receiving position to the medicine charging position, and a second belt conveyor that runs parallel to the first belt conveyor unit and extends horizontally from the medicine receiving position to the medicine charging position. A belt conveyor unit; a guide member provided obliquely to a conveyance path of the first belt conveyor unit; and a shutter member that opens and closes a conveyance path tip of the second belt conveyor unit. It is.

  However, when the above basic problem is solved by the realization of such a medicine bagging machine, further solution of the problem is also required. Specifically, it is a further technical problem to make the mounting compact without impairing the function and performance of the medicine feeding mechanism in which a plurality of belt conveyor units run side by side. In addition, regarding the opening of the medicine bag and the acceptance of the medicine, it is required to devise technical measures so that preparation of the medicine bag can be made more gently and without damage to the medicine container. .

  The drug bagging machine of the present invention (Solution means 1) was devised to solve such problems, and a drug bag holding mechanism that opens the mouth by holding the drug bag at or below the drug input position. And a medicine bagging machine comprising a medicine transporting mechanism for transporting and dropping medicine to the medicine charging position, wherein the transport mechanism extends horizontally from the medicine receiving position to just before the medicine charging position. A unit, a second belt conveyor unit juxtaposed below and extending horizontally to the medicine loading position, a guide member provided obliquely to a transport path of the first belt conveyor unit, and the first belt conveyor And a shutter member that opens and closes the front end of the conveyance path of the unit.

The drug bagging machine according to the present invention is (the solution means 2), which is the drug bagging machine according to the solution means 1, wherein the second belt conveyor unit can move forward or backward toward or beyond the drug input position. It's like that.
Furthermore, the medicine bagging machine of the present invention is (the solution means 3), which is the medicine bagging machine of the solution means 1 and 2, wherein rollers are arranged on the guide surface of the guide member. .
The drug bagging machine according to the present invention (solution means 4) is the drug bagging machine of the above solution means 1 to 3, wherein the drug bag holding mechanism acts on the outer surface of the drug bag to open its mouth. 1 opening member and the 2nd opening member which acts also on the inner surface of the said medicine bag and opens the opening | mouth further are comprised.

Further, the drug bagging machine of the present invention is (Solution means 5), which is the drug bagging machine of the above solution means 1 to 4, in the middle of the transfer of the drug toward the drug receiving position, A flexible sheet member is suspended.
Further, the drug bagging machine of the present invention is (the solution means 6), which is the drug bagging machine of the above solution means 1-5, and is provided with a bite detection sensor for detecting opening and closing of the shutter member. Is.

  In such a medicine bagging machine of the present invention (Solution means 1), when the medicine to be charged is transferred to the transport mechanism at the medicine receiving position, it spreads on the transport path of the first belt conveyor unit. There is no worry of breaking. Then, it is transported toward the medicine loading position, at which time the medicine on the first belt conveyor unit is gathered by the guide member and gathered in the lateral direction, and is held in front of the medicine loading position by the shutter member, It is also collected in the vertical direction and collected. Then, when the medicine bag is ready, the medicine on the first belt conveyor unit is transferred onto the second belt conveyor unit, and further the medicine on the second belt conveyor unit is put into the medicine bag from the mouth of the medicine bag. .

  Thus, when the medicine is transported from the medicine receiving port to the medicine input position, the medicine is gathered by the guide member and at the same time aligned to some extent. This aligned and assembled function makes it possible to load the medicine into the medicine bag more gently than when the medicines are directly put into the medicine bag from the transporter and simply put apart through the conveyor. Therefore, this medicine bagging machine can gently and quickly carry out the medicine into the medicine bag.

Moreover, in this medicine bagging machine, by arranging the first and second belt conveyor units up and down, it becomes easy to narrow the width of the conveyance path to the minimum limit necessary for receiving the medicine, Since the drive motor and the transmission member need not be spread out side by side, the installation area can be reduced, and in this sense, compact mounting is facilitated. Further, since the shutter member opens and closes the front end of the transport path of the first belt conveyor unit instead of the front end of the transport path of the second belt conveyor unit, the shutter member is placed in front of the medicine charging position, and the shutter member In addition, there is no need to worry about interference with the medicine bag when mounting the drive member and the support member. This also contributes to compact packaging.
Therefore, according to the present invention, it is possible to realize a compact medicine bag filling machine that can gently and quickly put the medicine into the medicine bag.

  In the medicine bagging machine of the present invention (solution 2), the tip of the first belt conveyor unit does not reach the medicine charging position, while the second belt conveyor unit reaching the medicine charging position moves forward and backward. Therefore, the tip of the second belt conveyor unit can be brought close to the mouth of the medicine bag or can be temporarily inserted into the mouth, so that the medicine can be reliably introduced while reducing the impact.

In addition, the provision of a shutter member for the first belt conveyor unit, which is not a movable belt unit such as the second belt conveyor unit, but a fixed unit, also simplifies and compactly mounts the belt conveyor unit. Helpful.
Therefore, according to this invention, it is possible to realize a compact medicine bagging machine that can gently and quickly put medicine into a medicine bag.

  Furthermore, in the medicine bagging machine of the present invention (Solution means 3), when the medicine on the first belt conveyor unit is width-adjusted by the guide member, the medicine is more smoothly guided by the row of rollers. . Therefore, even if the guide surface is steeply inclined, that is, even if the oblique angle between the guide member and the first belt conveyor unit conveyance path is increased, the width is adjusted without inconvenience. It becomes possible to shorten the conveyance path. This also contributes to compact packaging.

In the medicine bagging machine of the present invention (Solution means 4), when opening the mouth of the medicine bag in preparation for medicine injection, first, the first opening member opens to a certain extent, and through the opened mouth. When it becomes possible to act on the inner surface of the medicine bag, the mouth of the medicine bag is further opened by the second opening member.
By acting not only on the outer surface but also on the inner surface of the medicine bag in this way, the mouth of the medicine bag is surely opened widely, so that the target of the medicine can be spread, so that the medicine can be quickly put into the medicine bag. .
Therefore, according to the present invention, it is possible to realize a compact medicine bagging machine that can gently and quickly put the medicine into the medicine bag.

In the medicine bagging machine according to the present invention (solution 5), when the medicine is transferred onto the first belt conveyor unit at the medicine receiving position, the medicine hits the sheet member and then on the first belt conveyor unit. Move on. Since the sheet member is flexible and suspended, the moving speed of the medicine is lowered without causing an impact to the medicine, and the sheet member is dropped directly below or near. Therefore, even if the transfer speed is increased, the impact of the drug is alleviated and the drug is prevented from being widely dispersed after the transfer. This is also useful for compact mounting of belt conveyor units.
Therefore, according to the present invention, it is possible to realize a compact medicine bagging machine that can gently and quickly put the medicine into the medicine bag.

  In the medicine bagging machine of the present invention (solution 6), since the opening / closing of the shutter member is detected by the biting detection sensor, the shutter member tries to close the front end of the conveyance path of the first belt conveyor unit. If it does not close at this time, it can be detected that the medicine is being bitten. When the biting of the medicine is detected, the shutter can be opened and the medicine can be recharged by retrying the medicine insertion.

As a result, when the medicine is sent from the first belt conveyor unit to the second belt conveyor unit, it is not necessary to take extra waiting time for completion of feeding, so that the transport time and hence the medicine charging time can be shortened. It becomes.
Therefore, according to the present invention, it is possible to realize a compact medicine bagging machine that can gently and quickly put the medicine into the medicine bag.

About the chemical | medical agent bagging machine of such this invention, the specific form for implementing this is demonstrated by the following Examples 1-6.
The embodiment 1 shown in FIGS. 1 to 3 embodies the above-described solving means 1 to 3 (claims 1 to 3 as originally filed), and the embodiment 2 shown in FIG. Means 4 (claim 4 at the beginning of the application) is embodied, and the third embodiment shown in FIG. 5 embodies the solution means 5 (claim 5 at the beginning of the application) described above. The fourth embodiment shown in FIG. 6 embodies the above-described solution 6 (claim 6 at the beginning of the application).

Moreover, Example 5 shown in FIG. 7 is a modification. Furthermore, Example 6 shown in FIG. 8 is those application examples, and is a dispensing system which cooperates with other apparatuses.
In these drawings, for simplification and the like, a housing panel, a fastener such as a base, a frame, and a bolt, a coupling tool such as a hinge, a drive source such as an electric motor, a transmission member such as a timing belt, and a motor Electrical circuits such as drivers and electronic circuits such as controllers are not shown in the drawings, and those necessary and related to the explanation of the invention are mainly illustrated.

  About the Example 1 of the chemical | medical agent bagging machine of this invention, the specific structure is demonstrated referring drawings. FIG. 1 is a perspective view showing the structure of the main part.

  The medicine bagging machine 10 includes a medicine bag holding mechanism 20 for holding the medicine bag 2 in a single-sheet form so that the medicine can be charged, and a transport mechanism 30 as a medicine charging mechanism for charging the medicine into the medicine bag in a casing (not shown). It is equipped. In addition to the printing on the medicine bag, the printer 11 that also forms the medicine bag into a single sheet, the lifter 12 and the shifter 13 that transfer the medicine bag 2 from the printer 11 to the medicine bag holding mechanism 20, and the medicine 3 from the medicine tray 4 at the medicine receiving position. The arm 14 to be transferred to the transport mechanism 30 is also provided in the housing in this example, but these may be externally attached or not essential. In addition, a conveyor 5 for carrying the medicine tray 4 containing the medicine to be charged and a conveyor 7 for carrying out the medicine bag tray 6 containing the medicine bag 2 after the medicine is charged are partly incorporated in the medicine bagging machine 10, It extends inside and outside the housing. These are all controlled in accordance with a program by a controller (not shown) so as to perform a cooperative operation.

  The printer 11 prints information on the medicine to be put on the long and continuous medicine bag material 1 and cuts it after sending it out by a predetermined length. In addition, one of the cutting parts is sealed by heat welding or the like. In this way, the medicine bag 2 in a single-cut state is created. The unsealed cut portion of the medicine bag 2 becomes a mouth 2a that can be opened and closed. The medicine bag material 1 is made of a transparent and soft plastic film, formed into a long cylindrical body, and rolled up into a roll paper shape. Drug information is obtained from prescription data, derived dispensing data, and the like. For example, drug names, quantities, patient names, and the like are printed.

  The shifter 13 is composed of a belt conveyor or table on which the medicine bag 2 can be mounted, and the medicine bag 2 is unfolded by horizontally transferring the single medicine bag 2 discharged from the printer 11 in synchronization with the discharge speed. It is supposed to be received at. The lifter 12 lifts the medicine bag 2 on the shifter 13 by vacuum suction or the like and transports it onto the plate 22 of the medicine bag holding mechanism 20 so that the medicine bag 2 is transferred while being spread horizontally. Such medicine bag transfer means 12 and 13 may be omitted if the next opener 21 or plate 22 is disposed there.

  The medicine bag holding mechanism 20 is provided with a plate 22 that receives the medicine bag 2 and an opener 21 that opens the mouth 2a. The plate 22 is formed of a substantially flat plate-like body, and a small hole for vacuum suction or the like is formed on the holding surface of the medicine bag 2. The plate 22 is supported by the support shaft 23 so as to be swingable and rotatable. The state of can be taken. The holding surface is also facing upward in a horizontal state. The opener 21 is also formed of a substantially flat horizontal plate-like body, and has a small hole for vacuum suction formed on the lower surface thereof, and is supported above the plate 22 so as to be movable up and down. In any case, the vacuum suction surface / vacuum suction range is narrower than that of the medicine bag 2, and the mouth 2a is opened widely by adsorbing and separating the medicine bag 2 from above and below. Note that the opener 21 and the lifter 12 may be integrated to reduce the number of parts and to omit the delivery process.

  The transport mechanism 30 transports the medicine 3 from the medicine receiving position to the medicine charging position and drops it, so that a conveyor 32 (first belt conveyor unit) and a conveyor 31 (second belt conveyor unit) provided therebetween are provided. It is equipped with. Each of the conveyors 31 and 32 is obtained by extending an endless belt horizontally, and at least an upper surface portion forming a conveyance path is horizontal. However, since the horizontal definition in the present invention is not strict, even if there is a slight inclination, the drug 3 placed quietly on the transport path is naturally formed as long as it is not inconvenient for drug transport. If the inclination is small enough not to roll out, the conveyance path is practically horizontal.

  The conveyor 32 has a wider width than the conveyor 31 in order to receive the medicine 3 transferred and scattered from the medicine tray 4 at the medicine receiving position, and extends horizontally from the medicine receiving position to the front of the medicine loading position. . It does not reach the drug injection position, but before that. The upper surface of the conveyor 32, that is, the conveyance path surface, is provided with a surrounding plate 37 (fixed side plate) fixed to three sides around the medicine receiving position so that the medicine 3 is not spilled and dropped at the time of transfer, and a medicine input position that is the conveyance direction. It is surrounded by guides 34 and 35 (guide members) and a shutter 36 (shutter member) provided at the front side. The shutter 36 opens and closes the conveyance path at the tip of the conveyor 32, and has a lateral width that is narrower than the conveyor 32 and is substantially equivalent to the conveyor 31.

  The guides 34 and 35 are provided separately on both sides of the conveying path of the conveyor 32, and both guide the end of the shutter 36 and the end of the surrounding plate 37 in order to gradually narrow the effective width of the conveying path. In this case, it crosses the conveyance path. Of the side surfaces of the guide 34, the surface facing the conveyance path of the conveyor 32 is a guide surface for guiding the medicine 3 being conveyed, and the guide surface has a vertical surface for smooth guidance of the medicine 3. A large number of rollers 34a rotatably supported by a support shaft are arranged in a line. Of the side surfaces of the guide 35, the surface directed toward the conveyance path of the conveyor 32 is also a guide surface for guiding the medicine 3 being conveyed, and is also rotatably supported by a vertical support shaft on this guide surface. A large number of rollers 35a are arranged in a line.

  The conveyor 31 is installed in a state where the rear end portion is in parallel with the lower portion of the conveyor 32, and the front end extends to the medicine charging position. This is provided with an appropriate linear reciprocating drive mechanism (not shown) so that the conveyor 31 itself can be advanced and retracted in the same direction as the conveying direction, that is, toward the medicine charging position. As described above, the width of the conveyor 31 is narrower than that of the conveyor 32 so that the tip of the conveyor 31 can enter the medicine bag 2 from the mouth 2a when moving forward to the medicine charging position. The upper surface / conveyance path of the conveyor 31 is surrounded on both sides by a surrounding plate 37 and the rear end is surrounded by the front ends of the shutter 36 and the conveyor 32, but the front end is not enclosed.

The conveyor speeds of the conveyors 31 and 32 can be changed or adjusted by setting parameters of the controller, etc., but in this setting, is the conveyor speed of the conveyor 31 the same as the conveyor speeds of the conveyor 32 and the conveyor 33? In order to increase the speed, conditions are imposed by the program or the set value is corrected.
The forward speed of the conveyor 31 can also be changed or adjusted by parameter setting of the controller, but the backward speed of the conveyor 31 is automatically set to be the same as the transport speed of the conveyor 31. In addition, the controller is programmed to cause the conveyor 31 to perform the forward movement immediately when the shutter 36 is opened for charging the medicine.

  In addition, the medicine bagging machine 10 is provided with a medicine transfer means including an arm 14 or the like in the vicinity of the medicine bag receiving position in response to the automatic delivery of the medicine 3 to be packaged. The arm 14 tilts the medicine tray 4 carried by the conveyor 5 at the medicine bag receiving position and transfers the medicine 3 from the medicine tray 4 onto the transport path of the transport mechanism 30. The illustrated type is a push-up type, but it may be a pulling type or a holding type as long as it can be transferred.

The drug tray 4 is a small box made of plastic, and has a bowl-shaped protruding portion formed on the edge of the upper surface opening. The conveyor 5 is configured to convey the protruding portions on the two sides of the medicine tray 4 from above and below. As a result, the conveyance noise and other noises and vibrations are almost eliminated. Compared with the entire bottom surface transport mechanism, the collar transport has a simple structure and is easy to maintain.
The medicine bag tray 6 is also a plastic box having an open top surface. This is not only limited to the conveyance by the conveyor 7, but also by hand, and the number of medicine bags 2 after the bagging is not limited to one. -Since a large number of containers may be accommodated, the conveyor 7 carries the medicine bag tray 6 by placing the bottom surface of the medicine bag tray 6 on the belt, and at that time, the conveyor 7 passes or temporarily stops below the medicine charging position. It is like that.

  About the chemical | medical agent bagging machine of this Example 1, the use aspect and operation | movement are demonstrated referring drawings. FIGS. 2A to 2E are all plan views of the transport mechanism, and show an aligned set state associated with the medicine transport operation in time series. FIGS. 3A to 3D are all side views of the vicinity of the medicine loading position for the transport mechanism and the medicine bag holding mechanism, and show the medicine loading operation in time series.

  In this medicine bagging machine 10, several medicines 3 to be packed together are accommodated in a medicine tray 4 and carried on a conveyor 5, and a medicine bag 2 packed with medicines 3 is accommodated in a medicine bag tray 6. The medicine 3 used in an environment where the medicine 3 is taken out and received from the medicine tray 4 is received from the medicine tray 4 and put into the medicine bag 2, and information on the medicine to be put into the medicine bag 2 is printed. Do. The input preparation and information printing are performed in parallel as much as possible to improve the throughput.

  That is, (refer to FIG. 1), the necessary medicine 3 is collected based on prescription data, etc., and when the medicine tray 4 containing the medicine 3 is carried in or when a notification of the carrying-in schedule is received, the printer 11 follows the instructions of the controller. The medicine bag 2 in a single-cut state on which the information of the medicine 3 is printed is created. The medicine bag 2 is transferred to the medicine bag holding mechanism 20 by the lifter 12 and placed on the horizontal plate 22 to be adsorbed. In this way, it is held at the medicine loading position. Then, the mouth 2a of the medicine bag 2 is opened widely by a series of operations of the opener 21, specifically by operations of descending, adsorbing and ascending. Thus, the medicine bag 2 is held at the medicine input position with the mouth open, and the medicine bag 2 side is in a state where the medicine can be input.

  On the other hand (see FIG. 1), when the medicine tray 4 is transported to the medicine receiving position by the conveyor 5, the medicine tray 4 is tilted by the arm 14, so that the medicine 3 contained therein is transported by the conveyor 32. Move to the street. Since the conveyance path of the medicine receiving position is widely secured by the surrounding plate 37, the medicine 3 is not spilled and does not collide or overlap even if it is quickly moved (FIG. 2 (a)). reference). In this way, the transfer of the medicine 3 is performed quickly and safely.

  Then, the transport mechanism 30 starts the transport operation, specifically, the conveyor 32 is operated, and the medicine 3 is transported from the medicine receiving position to the medicine loading position (from left to right in FIG. 2). At that time, when the medicine 3 comes into contact with the rollers 34a and 35a of the guides 34 and 35 along with the conveyance, the medicine 3 is smoothly brought to the center along the guide surfaces (see FIG. 2B). They are aligned and gathered in front of the shutter 36 (see FIG. 2C). Thus, when the medicine 3 is stored in front of the shutter 36, the shutter 36 is operated and the medicine 3 is delivered from the conveyor 32 to the conveyor 31 (see FIG. 2D).

At this time, since the conveyor 31 performs a forward operation in addition to the transport operation, the medicine 3 is transported while being spread to some extent in the traveling direction without being scattered undesirably to the side and hardly overlapping vertically. (See FIG. 2 (e)).
In this way, the medicine 3 can be put into the medicine bag 2 on the conveyor 31. In addition, at that time, the medicine 3 develops moderately and waits for input in an orderly manner.

  When the medicine 3 is transferred to the conveyor 31 and the medicine bag 2 opens the mouth 2a at the medicine input position and preparation for preparation is made (see FIG. 3A), the conveyor 31 moves forward and enters the medicine bag 2 together with the medicine 3 from the tip. (See FIG. 3B). When the conveyor 31 has sufficiently advanced to the depth of the medicine bag 2, the conveyor 31 turns from advancing to retreating. Since the transport operation is performed at the same speed during the backward movement (see FIG. 3C), the medicine 3 falls in order from the tip, but the medicine is offset by the offset between the transport speed of the conveyor 31 and the backward speed. The horizontal speed of 3 is almost zero. Thus, the medicine 3 gently falls and is put into the medicine bag 2, and the conveyor 31 comes out of the medicine bag 2 (see FIG. 3D).

  When the injection of the medicine is completed (see FIG. 1), the medicine bag 2 is sealed by a heat seal member or the like (not shown) while the mouth 2a is held by the plate 22, and the transition of the plate 22 to the vertical state and the adsorption stop are performed. Is put into the medicine bag tray 6. In this way, the process of filling the medicine 3 in one medicine bag 2 is completed. Then, if it is OK to carry it out alone, or if it is carried out together with other medicine bags 2, the medicine bag tray 6 containing the medicine bags 2 is transferred to the conveyor 7 after repeating the above-described bagging operation as necessary. It is carried out by.

  Thus, in this medicine bagging machine 10, automatic processing of medicine bag bagging is executed safely and quickly with a higher throughput (efficiency) than conventional medicines even in fragile containers such as ampoules. The

About the Example 2 of the chemical | medical agent bagging machine of this invention, the specific structure is demonstrated with reference to drawing. 4 shows another structure of the medicine bag holding mechanism, and shows the opening operation of the medicine bag in time series, (a) to (c) are perspective views of the first opening member, and (d) to (f) are second views. It is a side view of an opening member.
This medicine bag holding mechanism 40 is different from the medicine bag holding mechanism 20 of the first embodiment described above in that it has a two-stage configuration of a first opening member 41 and a second opening member 45.

  The first opening member 41 (see FIGS. 4 (a) to 4 (c)) acts only on the outer surface of the medicine bag 2 to open the mouth 2a to some extent. A vacuum tube 42 (vacuum suction member) is provided. The vacuum tube 42 provided on the upper side adsorbs a portion of the outer surface of the medicine bag 2 close to the mouth 2a and lifts it upward instead of the opener 21 described above. In addition, the vacuum tube 42 provided on the lower side adsorbs a portion close to the mouth 2a on the outer surface of the medicine bag 2 in place of the plate 22 described above and pulls it down. The medicine bag holding mechanism 40 is also provided with a plate 43, but this does not have an adsorption function, and the plate 43 carries the medicine bag 2 and adjusts the posture of the medicine bag 2 to a horizontal and flat state. .

  The second opening member 45 (see FIGS. 4D to 4F) acts on both the outer surface and the inner surface of the medicine bag 2 to further open the mouth 2a. A separation member 46 that is provided to be separated / proximate to each other according to the control of the controller and a pair / set of a movable holding member 47 and a fixed holding member 48 provided on each separation member 46 are provided. The fixed clamping element 48 provided on the upper separation member 46 presses the outer surface of the medicine bag 2 near the mouth 2a from above, and the movable clamping element 47 provided on the same separation member 46 has The tip portion of the medicine bag 2 is driven to rotate and enters the medicine bag 2 from the mouth 2a to push up the inner surface of the medicine bag 2 from below, and the pair of the movable clamp 47 and the fixed clamp 48 of the mouth 2a of the medicine bag 2 The upper edge part is clamped. Although the vertical relationship is reversed, similarly, the pair of the movable clamp 47 and the fixed clamp 48 provided on the lower separation member 46 also clamps the lower edge portion of the mouth 2a of the medicine bag 2 from inside and outside. It has become.

  In this case, since the vacuum tube 42 also serves as the above-described lifter 12, when the single-pack medicine bag 2 on which the information of the medicine 3 is printed by the printer 11, the medicine bag 2 is opened by the vacuum tube 42. The vicinity of 2a is gripped (see FIG. 4A), and in this state, the vacuum tube 42 is moved to the medicine input position. At that time, the posture is corrected by using the plate 43 (see FIG. 4B). Then, the vacuum tube 42 moves up and down, and the mouth 2a is slightly opened. Specifically, the movable holding element 47 is opened to such an extent that it can enter (see FIG. 4C).

  The medicine bag 2 carried to the medicine charging position (see FIG. 4D) has the mouth 2a between the upper and lower fixed clamps 48, and when the mouth 2a is opened by the first opening member 41, The outer surface of the upper edge portion of 2a hits the upper fixed clamp 48, and the outer surface of the lower edge portion of the mouth 2a hits the lower fixed clamp 48. Then, when the movable clamp 47 rotates and enters the mouth 2a, and the mouth 2a of the medicine bag 2 is clamped by the movable clamp 47 and the fixed clamp 48 (see FIG. 4 (e)), the first opening member 41 Escapes and the separation member 46 is separated vertically.

If it does so, the movable holding element 47 and the fixed holding element 48 will also be separated up and down, pinching the edge part of the opening | mouth 2a of the medicine bag 2 accompanying the separation member 46 (refer FIG.4 (e)). At that time, since the mouth 2a of the medicine bag 2 is firmly clamped, the mouth 2a is further opened wide and surely opened.
In this way, the medicine bag 2 is held at the medicine charging position with its mouth wide open, and the medicine can be put into the medicine bag 2. Then, drug injection is performed in the same manner as in the above example.

  About the Example 3 of the chemical | medical agent bagging machine of this invention, the specific structure is demonstrated with reference to drawing. FIG. 5 shows another structure of the medicine bag holding mechanism and the transport mechanism around the medicine receiving position, and shows the medicine receiving operation by both mechanisms in chronological order, (a) is a perspective view of both mechanisms, and (b)-( e) is a side view as seen from the arrow A.

  This drug bagging machine is different from those of the first and second embodiments described above in that the conveyor 5 that transports the drug tray 4 is not behind the transport mechanism 30 but on the side of the transport mechanism 30 (in FIG. 5A). There are a point at the upper left), a point corresponding to the fact that there is no corresponding guide 35 and the surrounding plate 37 extends straight up to the shutter 36, and a point at which a buffer mechanism 50 is provided above.

  The buffer mechanism 50 is provided so as to be horizontally movable and is urged toward the conveyor 5 by a spring or the like (not shown), and three sheet members 52, 53, 54. The sheet members 52, 53, and 54 are made of soft and thin rubber, plastic, etc., and the sheet member 52 on the conveyor 5 side is suspended at the softest and highest position, and the sheet member 54 on the conveyor 32 side is compared although it is soft. In this case, the sheet member 53 is suspended at the hardest and lowest place, and the sheet member 53 between them is located between the members 52 and 54.

  In this case, the tilting of the medicine tray 4 is not performed by the arm 14 but by the tilting support shaft 55 on the side of the conveyor 32 and the tilting arm portion 56 extending from the tilting support shaft 55 toward the conveyor 5 (FIG. 5B). When the medicine tray 4 containing the medicine 3 is conveyed to the tilting arm part 56 by the conveyor 5, the tilting arm part 56 rotates and swings upward, and the medicine tray 4 is lifted while tilting. (See FIG. 5C). Then, the medicine 3 rolls out from the medicine tray 4, but the medicine 3 hits the sheet member 52 and tries to fall down slowly.

  When tilting of the medicine tray 4 by the tilting arm part 56 proceeds (see FIG. 5D), the tip of the tilting arm part 56 or a part of the medicine tray 4 comes into contact with the suspension part 51 to convey the suspension part 51 to the conveyor. Move toward 32. After the medicine tray 4 is sufficiently tilted (see FIG. 5 (e)), the sheet member 53 and the sheet member 54 are moved onto the conveyor 32, and the medicine 3 is gently conveyed by the appropriate braking action. Rolls down on 32 transport surfaces.

  Thus, the impact at the time of transferring the medicine is alleviated, so that the medicine 3 is transferred from the medicine tray 4 to the conveyor 32 without scattering so much, so there is no inconvenience even if the width of the conveyor 32 is somewhat narrowed. Moreover, since there is no possibility that the medicine 3 collides with the conveyor 32 and the surrounding plate 37 vigorously, the tilting speed of the medicine tray 4 can be increased without any inconvenience. Also in this case, the other operations are the same as those described in the first and second embodiments.

  About the Example 4 of the chemical | medical agent bagging machine of this invention, the specific structure is demonstrated with reference to drawing. FIGS. 6A and 6B show an installation example of the bite detection sensor, where FIG. 6A is a plan view of the transport mechanism, FIG. 6B is a side view of the B arrow, and FIG. 6C is a perspective view of the C arrow.

  This medicine bagging machine is different from those of the first to third embodiments described above in that the conveyor 31 entering the medicine bag 2 is thinned and the conveyor 31 is arranged in order to facilitate the arrangement of the drive shaft. The rear end portion of the conveyor 32 in order to make the rear end portion bent downward and the front end portion of the conveyor 32 thin to reduce the transport path step between the conveyor 32 and the conveyor 31 and to facilitate the arrangement of the drive shaft. Is bent downward, the transport path of the conveyor 32 is slightly inclined, for example, by 3 °, to make it easier to feed the medicine 3 from the conveyor 32 to the conveyor 31, and the shutter 36. A biting detection sensor 60 is provided for detecting the opening and closing of the sensor and sending the detection signal to the controller.

In this case, if the shutter 36 is normally opened and closed according to the control of the controller, the opening / closing state of the shutter 36 and the biting detection sensor 60 controlled by the controller, apart from the temporary / transitional period required for the transition of the opening / closing state. The detection result of the open / close state by coincides.
On the other hand, if the medicine 3 on the conveyor 31 is bitten when the shutter 36 is closed, the shutter 36 is not completely closed, and therefore the control state of the controller and the detection result of the biting detection sensor 60 match. Disappear.

In such a case, once the shutter 36 is opened, the conveyor 31 operates for a time sufficient to carry the bitten medicine 3 from under the shutter 36, and then the closing operation of the shutter 36 is retried. .
In this way, the opening / closing operation of the shutter 36 is accurately executed, and as a result, the medicine is reliably inserted.
In this case, the other operations are the same as those described in the first and second embodiments.

  About the Example 5 of the chemical | medical agent bagging machine of this invention, the specific structure is demonstrated with reference to drawing. 7A and 7B show another structure of the medicine bag transfer means that is also a front stage portion of the medicine bag holding mechanism, in which FIG. 7A is a perspective view, FIG. 7B is a side view of a part thereof, and FIG. It is. In the illustration, a heater 15 that seals the bottom 2b of the medicine bag 2 by heat fusion or the like, and a cutting line 16 when the front and rear medicine bags 2 are separated by a cutter are also schematically shown. For the loop conveyor 71, only its circulation path is shown.

  This drug bagging machine is different from those of the first to fourth embodiments described above in that the drug bag transfer mechanism 70 is composed of a loop conveyor 71 (circulation mechanism), a side clamper 72 (downward transfer clamp), and a plate 73 (receiving member, It is a point comprised by the vacuum tube 74 (horizontal transfer element, vacuum suction member). The medicine bag transfer mechanism 70 includes a first transfer path for lowering the medicine bag 2 separated after printing by the printer 11, and further horizontally moving the medicine bag 2 to open medicine bag opening means (specifically, the opener 21 and the first example above). And the second transfer path to be fed into the two opening members 45). The former first transfer path portion is composed of the loop conveyor 71 and the side clamper 72, and the latter second transfer path portion is the plate. 73 and a vacuum tube 74.

  The loop conveyor 71 is formed by extending an endless belt or chain on upper and lower rollers (not shown) to form a vertically long circulation path, and is separated by a distance corresponding to the width of the medicine bag 2 to form two circulation paths. Are running side by side. A portion of the circulation path that moves downward is used as the first transfer path. A plurality of sets (three sets in the figure) of side clampers 72 are mounted on the loop conveyor 71 at an equal pitch. Each group of side clampers 72 is composed of side clampers 72 provided in two circulation paths, and is divided into left and right sides so as to sandwich both sides of the medicine bag 2. Each side clamper 72 is composed of a pair of clamping pieces that move up and down to separate / approach in order to clamp one portion of the medicine bag 2 from above and below.

The plate 73 is for adjusting the posture of the medicine bag 2 from below, but the width is slightly narrower than that of the medicine bag 2 so as not to interfere with the side clamper 72. In addition to the horizontal movement in the second transfer path, this also moves up and down at the start point of the second transfer path (which overlaps the lower end of the first transfer path).
The vacuum tube 74 may be the same as the vacuum tube 42 described above, but only the upper two are provided because the vacuum tube 74 is linked and cooperates with the lower plate 73. The vacuum tube 74 also serves as the first opening member and acts on the mouth 2a of the medicine bag 2. Therefore, when the side clamper 72 clamps the medicine bag 2, the side of the mouth 2a is about several centimeters, for example, 2 to 3 cm. (See E in FIG. 7A).

In this case, since a plurality of sets of side clampers 72 are provided in place of the lifter 12 and the like which were only one set in the above-described example, the medicine bag 2 can be lowered and transferred one after another without interruption.
That is, the medicine bag 2 printed by the printer 11 or the like and created by the heater 15 or the cutter 16 is sandwiched by the side clamper 72 and lowered by the loop conveyor 71 (see FIG. 7A). . With respect to the lowered medicine bag 2, the plate 73 rises from below (see FIG. 7B). Therefore, when the mouth 2a of the medicine bag 2 hangs down, it is raised and becomes horizontal. Further, from above, the vacuum tube 74 descends in order to hold the medicine bag 2 by holding the mouth 2a and further adsorbing it. Furthermore, the side clamper 72 moves up and down to deliver the medicine bag 2 to them.

  And (refer FIG.7 (c)), the medicine bag 2 passed to the plate 73 and the vacuum tube 74 is horizontally transferred toward the chemical | medical agent injection position in the 2nd transfer path, and the side clamper 72 which passed the medicine bag 2 is a loop conveyor. In this case (see FIG. 7A), the other side clamper 72 has reached the medicine bag creation position of the printer 11, etc., so that it is created next. Since the downward movement of the medicine bag 2 is started immediately, the downward movement of the medicine bag 2 can be performed one after another without interruption.

  When the medicine bag 2 is clamped and lowered, the shape of the medicine bag 2 may be undesirably disturbed unless the entire medicine bag 2 is clamped or moved at a low speed. Since descending transfer can be performed, the efficiency, that is, the processing amount per unit time does not need to be reduced even if low speed movement is adopted. Therefore, the printer 11 and the like can be accommodated in an empty space at the top of the housing, the side clamper 72 can be downsized, and the loop conveyor 71 can be reduced in weight.

  The configuration of a dispensing system that is Embodiment 6 of the drug bagging machine of the present invention will be described. FIG. 8A is a plan view, and FIG. 8B is a front view.

  In this automatic dispensing system 80, in addition to the above-described medicine bagging machine 10, for example, a medicine dispensing machine 81 for automatically dispensing ampule-containing injection medicine and a liquid medicine contained in a small bottle of 50 ml or 100 ml, for example, are automatically used. A medicine dispensing machine 82 for dispensing the medicine, a tray supplier 83 for supplying an empty medicine bag tray 6, a medicine dispensing machine 84 for delivering a relatively large infusion bottle, and a soft kit medicine in a bag, for example. Also provided is a medicine dispenser 85 and a trace stocker 86 for stocking the medicine bag tray 6 containing the medicine bag 2 containing the medicine 3 so as to be ready for inspection or the like.

Among them, the medicine dispensing machines 81 and 82 are connected to the medicine bagging machine 10 via a conveying device including the conveyor 5, and the conveying path is completed (see the one-dot chain line with an arrow in FIG. 8). ), The medicine tray 4 is circulated.
Further, the tray supplier 83, the medicine dispensing machines 84 and 85, and the trace stocker 86 are connected to the medicine bagging machine 10 through a conveying device including the conveyor 7, and the medicine bag tray 6 is connected to the tray supplier 83, the medicine dispensing machine. 84, the medicine dispensing machine 85, the trace stocker 86, the medicine bagging machine 10, and the trace stocker 86 are again conveyed in that order (see the two-dot chain line in FIG. 8).

  In this case, when prescription data is transmitted from a higher-level prescription ordering system or the like (not shown), the automatic dispensing system 80 correspondingly sends out an ampoule or the like from the medicine dispenser 81, If a bottled medicine is prescribed, it is dispensed from the medicine dispensing machine 82, collected in the medicine tray 4, and carried into the medicine bagging machine 10 on the conveyor 5. In the medicine bagging machine 10, as described above, the medicine information is printed on the transparent medicine bag 2 and the medicine 3 such as an ampule is packed.

At the same time, an empty medicine bag tray 6 is sent out from the tray supplier 83. To the medicine bag tray 6, infusion bottles and soft kit medicines to be prescribed are dispensed from the medicine dispensing machines 84 and 85. Then, the medicine bag tray 6 passes through the trace stocker 86 and is carried into the medicine bagging machine 10 by the conveyor 7. Then, after the additionally filled medicine bag 2 is added, it is returned to the trace stocker 86.
Thus, in this automatic dispensing system 80, the medicine that can be packaged is sealed in a medicine bag so that it cannot be touched by human hands, and the medicine that is not suitable for bagging is not separated by using the tray. And prescription units.
