Description

TECHNICAL FIELD The present invention relates to a medicine packaging device that supplies and packs medicines one by one.

The most important requirements for automatic powder drug packaging machines that have been used for a long time to automate drug dispensing work are that the content of each package is the amount specified in the prescription, and that one The package should not be contaminated with non-prescription substances. The reason why the content of one package is reduced is that the medicine flies out from the middle of the medicine path and scatters, and the medicine remains adhered to the medicine path surface.

In the case where a different drug is to be packaged in the next prescription, if the remaining drug adhering to this path mixes with the new drug when it passes through, it can lead to the contamination of non-prescription substances. turn into.

In particular, the inner surface of the drop hopper, whose leading end is inserted into the V-folded packaging paper of the packaging machine and is used to introduce the falling powdered medicine from above, has a recessed shape, so the medicine tends to adhere. In addition, mechanical cleaning is difficult, and cleaning has been a major issue. Adhesion removal by mechanical tapping vibration or ultrasonic vibration has a certain effect, but as a more positive method, a suction method using air is also used as described in Patent Document 1.

In recent years, there has been an increasing need for fully automated powder medicine packaging machines, and as described in Patent Document 2, robot-type fully automatic powder medicine packaging machines have been put into practical use, which eliminate the need for a staff member to insert the medicine each time a prescription is given. .

Japanese Patent No. 4568082 JP-A-7-80043

In the device described in Patent Document 1, air is sucked by creating an air flow from the bottom to the top on the inner surface of the drop hopper, so foreign matter in the space can be taken into the hopper by sucking in new outside air from the lower outlet. have a nature. In addition, the powdered medicine itself falls from top to bottom due to gravity, and sucking it upward reduces efficiency. Furthermore, even if such residual chemicals are removed, it is not complete, and it is necessary to remove the drop hopper and wash it with water at a certain frequency.

In addition, in the device described in Patent Document 2, when cleaning the inner surface of the drop hopper, it is necessary to remove the drop hopper and wash it manually. Therefore, there has been a demand for realization of an apparatus capable of automatically removing adhered residual chemicals.

The problem to be solved by the present invention is to provide a drug packaging device that prevents contamination by substances other than prescriptions by removing residual drugs adhering to drop hoppers that receive drugs from a drug supply unit. do.

The medicine packaging device of the present invention comprises a medicine supply unit that supplies medicines one by one, an upper hopper that has an upper opening for receiving the medicines supplied from the medicine supply unit from above , and an upper hopper below the upper hopper. a lower hopper provided with a lower opening for discharging the drug from below ; a drop hopper that can move up and down as a whole; a medicine packaging unit, a high-pressure air blowing mechanism for blowing high-pressure air from above the upper hopper onto the inner surface of the drop hopper to drop residual medicine adhering to the inner surface of the drop hopper, and a lower opening of the drop hopper. and an air suction device that is selectively connected to and removes, from the lower opening , residual medicine adhered to the interior of the dropping hopper that has been dropped by the compressed air . do.

An automatic powder medicine packaging machine according to an embodiment will be described below with reference to the drawings.
In the following description, an automatic powder medicine packing machine will be taken as an example, but the present invention is not limited to the automatic powder medicine packing machine, and can of course also be applied to an automatic tablet packing machine. Powdered medicines are more effective than tablets because they are more likely to scatter and adhere, but an automatic tablet packaging machine can also provide the same effect of preventing contamination by unprescription substances.

FIG. 1 is a plan view of the automatic powder medicine packaging machine of this embodiment, and FIG. 2 is a front view of the automatic powder medicine packaging machine. Above the intermediate table 11 of the housing 10 is arranged a disk distribution section 100 as a drug supply section, and below the intermediate table 11 is arranged a printing packaging machine 200 as a drug packaging section. A drop hopper 300 serves to introduce the powdered medicine discharged from the disc distribution unit 100 through the inner surface of the drop hopper 300 into the printing packaging machine 200 side. It is an object of the present invention to remove the residual medicine adhering to the inner surface of the drop hopper 300 and remaining thereon.

The disc distributor 100 is provided with two sets of distributors. In the disc distribution unit 100, 101 is a detachable powdered medicine cassette, which is loaded with powdered medicine in the amount necessary for the prescription at another place in advance, and is placed on a shaking table from another shelf by an automatic device such as a robot arm (not shown). 102. The vibration table 102 generates vibration by an electromagnet (not shown) or the like, and by transmitting the vibration force to the powdered medicine cassette 101, the powdered medicine in the powdered medicine cassette 101 is transported by vibration, and the powdered medicine is dropped little by little in the direction of the arrow 103. It is.

Reference numeral 104 denotes a horizontally arranged distribution disk, a large circular wheel of which is rotated by a stepping motor 105 via a gear 106 in the direction of an arrow 104a. Further, an arcuate concave surface 107 is formed on the upper surface of the distribution disk 104 in the outer peripheral direction. Here, when the vibrating table 102 is driven while the stepping motor 105 is continuously rotated, the powdered medicine falls little by little onto the arcuate concave surface 107 of the distribution disc 104 to form a donut-shaped powdered medicine mountain P1. can be done. This operation is called a "circumferential scattering operation".

Reference numeral 108 denotes a scraping disk portion, and a lever 108a can rotate up and down around a shaft 109. As shown in FIG. A disk 110 made of silicon rubber is attached to the tip of the lever 108a, and can be rotated in the direction of an arrow 110a by a motor 111. As shown in FIG. This disk 110 has a waterwheel-like shape in which blades are provided between two discs. It should be noted that the disk diameter of the disc 110 is the same as the diameter of the concave surface of the arcuate concave surface 107 .

In the case of the above-mentioned "circumferential scattering operation", this disk 110 is retracted upward and does not interfere with the formation of the donut-shaped powdered drug pile P1. Next, during the "one-pack distribution operation", the disk 110 of the scraping disk portion 108 rotates downward, and the disk 110 comes into close contact with the arc-shaped concave surface 107 without any gap. In this state, when the motor 111 is driven, the blades provided on the disk of the disk 110 scrape the powdered medicine on the arcuate concave surface 107 onto the drop hopper 300 . Then, when the stepping motor 105 is rotated by a predetermined angle R, the amount of powdered medicine corresponding to that angle is dispensed to the drop hopper 300 side. Here, the aforementioned predetermined angle R is the angle for the dose to be packaged in a single packet separately specified by the prescription.

For example, in the case of making a prescription for 36 packets of a powdered medicine with a weight of 1g per packet, 36g of powdered medicine is loaded into the powdered medicine cassette 101 in advance, and this is carried out by the "circumferential spreading operation". Spread the entire amount evenly in a donut shape. Next, in the "single package distribution operation", when the stepping motor 105 is rotated by 10 degrees while the disc 110 is being rotated, one package of 1 g of powdered medicine can be correctly dispensed to the drop hopper 300. be.

The disc distribution unit 100 has two pairs of discs 112a and 112b arranged symmetrically in the left and right direction. The disc portion 112b of the prescription is capable of performing "one package dispensing operation" so that a plurality of consecutive prescriptions can be continuously dispense-packaged without wasting time.

FIG. 3 outlines the shape and operation of the drop hopper 300 . The drop hopper 300 has a double structure of an upper hopper 301 and a lower hopper 302, and a lower opening 303 of the upper hopper is closed by a shutter 304 that can be opened and closed. The upper end of the upper hopper 301 is formed with an upper opening 300a for receiving the powdered medicine from the distribution disc 100. As shown in FIG. The lower end of the lower hopper 302 is formed in a wedge shape as shown in FIGS. ) 305c are formed. The drop hopper 300 can move up and down as a whole. Then, at the timing of dispensing the powdered medicine from the disc distribution unit 100 in the "one packet dispensing operation", it is positioned at the upper position in FIGS. 3(a) and 3(b). At this time, the shutter 304 is closed as shown in the side view of FIG.

At this time, the left and right claw portions 305a and 305b at the lower end of the drop hopper 300 are inserted into the open end B1 of the conveyed packaging paper B that has been folded in two into a valley fold.

When the powdered medicine is discharged, as shown in FIG. 3(c), the entire drop hopper 300 moves downward. It acts as a guide to the times. When the shutter is opened as shown in 304a in this state, the powdered medicine is stored inside the packaging paper B. FIG. After that, the drop hopper 300 rises to the position shown in FIG. 3(b).

Next, the configuration and operation of the printing packaging machine 200 will be described with reference to FIGS. 4 and 5. FIG. FIG. 4 is a front cross-sectional view of the powdered drug dispensing machine, showing a state in which the drop hopper 300 positioned above in FIG. 2 has moved downward. FIG. 5 is a top cross-sectional view of the printing and packaging machine 200. As shown in FIG. Reference numeral 201 denotes a packaging paper roll, which is formed by winding up a double-folded thermal adhesive paper on a reel with the valley-fold side facing downward. The paper is pulled out from the leading edge of the paper on the outer peripheral side of the reel and conveyed along the route shown by the one-dot chain line B2 to B3. A printing unit 202 is composed of an ink ribbon 203, a thermal printing head 204, a platen roller 205, etc., and prints prescription information on the surface of the packaging paper B for each package.

A vertical sealing mechanism 206 presses the packaging paper B from the front and back (up and down in FIG. 5) with a hot plate to effect vertical sealing as indicated by 207a. 207b shows the sealing at the position moved by one package, but the upper open end 208 of the packaging paper B is not sealed. This is so that the packing sheets B can be transported in a state in which the claw portions 305a and 305b of the drop hopper 300 are inserted between the packing sheets B as shown in FIG. 3(a). A drop hopper cleaning device 310 is attached to the far side of the drop hopper 300 arranged next. The drop hopper cleaning device 310 will be detailed later.

Next, 209 is a horizontal sealing mechanism, which presses the packaging paper B from the front and back with a hot plate to seal the unsealed portions in the horizontal direction and the vertical direction as indicated by 210 . With the vertical seal 207 and the horizontal seal 210, the packaging paper B is sealed as a single package.

A driving roller 211 is driven synchronously with the platen roller 205 of the printing unit 202, and is driven by a distance of a pitch B4 for one package of the packaging paper B as one step. A cutter 212 is provided at the outlet, and cuts the packaging paper B when the continuous individual packaging for one prescription is completed.

In addition, as accessories of the drop hopper cleaning device 310, which will be described in detail later, a dust collection blower 401 and a compressed air generating compressor 402 are arranged at the rear of the housing and used as air sources for the drop hopper cleaning device 310, respectively. be.

The structure and operation of the drop hopper cleaning device 310 will be described below with reference to FIGS. 6 to 12. FIG. FIG. 6 is a perspective view of the drop hopper cleaning device 310, showing a state in which the drop hopper section 300 is removed. Also, FIG. 7 shows a state in which the drop hopper 300 is attached. Furthermore, FIG. 8 shows a state in which the vertical movement mechanism of the drop hopper 300 is removed.

9 is a side sectional view when the drop hopper 300 is in the upper position, and FIG. 10 is a side sectional view when the drop hopper 300 is in the lower position. 11 is a perspective view showing the cleaning operation position, and FIG. 12 is a side sectional view showing the cleaning operation position. In addition, in order to make it easy to understand, some parts are omitted in the drawing.

Each mechanism is mounted on the base 311, and each actuator is configured to perform the following functions.

(1) Mechanism for Vertical Movement of Falling Hopper In FIGS. 6 and 9, a first motor (not shown) attached to a shaft 312 is a drive source, and a first cam 313 and a second cam 314 are attached to the shaft 312. It is attached. A drop hopper mount 315 has a shaft 317 attached to the bottom of the drop hopper mount 315 . Further, the shaft 317 is inserted in a linear motion bearing 316 so that the drop hopper mounting base 315 can move up and down in the axial direction of the shaft 317 .

That is, when the first motor (not shown) rotates by a predetermined angle, the first cam 313 pushes up the cam follower 318. As the cam follower 318 rises, the arm 319 rotates clockwise about the shaft 320. Move drop hopper mount 315 upward. The position is shown in FIG. Further, by rotating the first motor in the reverse direction, the drop hopper mount 315 is moved to the position shown in FIG. These correspond to FIGS. 3(b) and 3(c), which have been outlined in FIG.

(2) First Opening and Closing Mechanism of Drop Hopper Shutter In FIGS. 6 and 7, the shutter 304 in the drop hopper 300 is closed when the drop hopper 300 is in the upper position and opened when the drop hopper 300 is in the lower position by the first opening and closing mechanism. It is configured so that it can be driven to open and close so as to be positioned. First, the first motor (not shown) rotates to move the drop hopper 300 downward from the state where the drop hopper 300 is at the upper position. As the first motor rotates, the second cam 314 attached to the shaft 312 also rotates, causing the cam follower 322a attached to the lower end of the arm 322 rotating about the shaft 321 to move to the second cam. 314 presses. This pressure causes the arm 322 to rotate counterclockwise. By this rotation, the tip 322b of the arm 322 pushes the lever 323 attached to the shutter 304, thereby opening the shutter to the position 304a (FIG. 10).

As described in (1) and (2), the vertical movement of the drop hopper 300 and the opening and closing of the shutter 304 are synchronized by the first cam 313 and the second cam 314 of the shaft 312, and the drop hopper 300 is When the drop hopper 300 is in the down position, the shutter 304 is "open".

(3) Hopper hitting mechanism 324 shown in FIG. 6 is a hitting mechanism which is a first vibrating device rotationally driven by a solenoid (not shown). and drop the remaining medicine adhering to the inside of the drop hopper 300 .

When one package of powdered medicine is put into the drop hopper 300 from the disk distribution unit 100 side during the "one-pack distribution operation", the drop hopper 300 is in the upper position and the powdered medicine is held on the closed shutter 304. be. When one packet of powdered medicine has finished dropping, the first motor is driven to move the drop hopper 300 downward, and the recessed portion 305c of the drop hopper 300 enters between the packaging sheets B, and the shutter 304 However, by opening, the powdered medicine is accommodated between the packing sheets B. Also, at the timing when the shutter 304 opens, the hopper hitting mechanism 324 is operated multiple times to drop the remaining medicine adhering to the drop hopper 300 onto the packing paper B side. It is designed to be

When the powdered medicine is stored in the packaging paper B, the first motor is reversed to move the drop hopper 300 to the upper position. After that, the packaging paper B is transported by the driving roller 211 and the platen roller 205, printed by the printing unit 202, and sealed by the vertical sealing mechanism 206 and the horizontal sealing mechanism 209, and the processing for one package is completed. Even if the drop hopper 300 moves to the upper position, the claws 305a and 305b of the drop hopper 300 are still inserted between the packing sheets B, but the upper portion of the packing sheets B is sealed by the vertical sealing mechanism 206. Since the sealing is not performed, the movement of the packaging paper B is not hindered.

Then, the drop hopper 300 is moved upward to wait for the drop of the next packet of powdered medicine. By repeating this series of operations, a plurality of individual packages for one prescription are completed.

Next, for cleaning the drop hopper 300, a drop hopper cleaning device 310 is provided with the following mechanism.

(4) Air Suction Mechanism As shown in FIG. 9, when the drop hopper 300 is at the upper position, it faces the wedge-shaped recess 305c formed in the lower part of the drop hopper 300, and sandwiches the recess 305c from both sides. A pressure member 328 is provided on one side of the wedge to block the opening to form a closed air flow path. A suction element 329 for sucking air from the opening is provided on the other side of the wedge. The pressing element 328 and the attracting element 329 form a suction mechanism. In the non-sucking state, the pressure element 328 and the suction element 329 are in an open state as shown at 328a and 329a, as shown in FIG.

For suction, when the second motor 331 shown in FIG. 11 rotates, the cam 332 attached to the shaft of the motor 331 rotates to move the link 333, which also serves as a cam follower, upward. As the link 333 moves, the presser 328 rotates clockwise about the shaft 334 as indicated by the arrow 335 in FIG. Then, as indicated by 328b, one side of the wedge in which the concave portion 305c of the drop hopper 300 is formed is covered through the packaging paper B, thereby blocking one side of the lower opening.

As the link 333 moves upward, the attractor 329 advances in the direction of the arrow 336 by a moving mechanism (not shown) and moves from 329a to 329b. As a result, the attracting element 329 is brought into pressure contact with the other side of the wedge of the drop hopper 300 in which the concave portion 305c is formed. A conduit 337 through which air passes is formed inside the adsorber 329 and is connected to the dust collection blower 401 via a pipe 338 .

As shown in FIGS. 11 and 12, when the dust collection blower is driven with the pressing element 328 and the attracting element 329 in the states 328b and 329b and blocking the recess 305c of the drop hopper 300, the air in the drop hopper 300 is can flow into the dust collection blower side. At this time, the claws 305a and 305b, which are projections at the lower end of the drop hopper 300, are inserted between the packing sheets B, but the recess 305c of the dropping hopper 300 is above the packing sheets B. Therefore, air can be sucked through this recess 305c. As a result, an air flow is formed in the drop hopper 300 from the top to the bottom, and the remaining medicine adhering to the inside of the drop hopper 300 can be removed. In this manner, since a part of the drop hopper 300 can be washed while being inserted between the packing sheets B for washing, the next prescription operation can be performed continuously.

(5) Compressed Air Blowing Mechanism As shown in FIGS. 6 and 8, the air conduit 325 connected to the compressor (high-pressure air generator) 402 shown in FIG. Contiguous. As a result, the high-pressure air generated by the compressor 402 is blown onto the inner surfaces of the four corners of the drop hopper 300 located at the upper position, so that the remaining medicine adhering to the inside of the drop hopper 300 can be dropped.

(6) Second Opening/Closing Mechanism of Shutter of Falling Hopper The first opening/closing mechanism of the shutter described in (2) opens and closes in synchronization with the vertical movement of the dropping hopper 300 . The second opening/closing mechanism of the shutter 304 constitutes a second vibrating device that vibrates the drop hopper 300 by opening and closing the drop hopper 300 at the upper position. As shown in FIG. 8, a cam 340 is attached to the shaft 339a of the third motor 339. As shown in FIG. By driving the third motor 339, the cam 340 is rotated, which laterally moves the arm 341. When the tip of the arm 341 pushes the lever 323 attached to the shutter 304, the shutter 304a is moved. position (Fig. 12). Further, by rotating the third motor 339 a plurality of times, the shutter 304 is repeatedly opened and closed, thereby vibrating the drop hopper 300 .

The first opening/closing mechanism of the shutter 304 described in (2) cannot operate unless the drop hopper 300 moves up and down. can. When this opening and closing is performed a plurality of times, the shutter 304 hits the lower end of the upper hopper 301 and the inner surface of the lower hopper, and vibration can be applied to the drop hopper 300 . Remaining medicine adhering to the upper hopper 301, the lower hopper 302 and the shutter 304 can be dropped. Therefore, by applying vibration to the drop hopper 300 at the same time as the drop hopper cleaning device 310 sucks the drop hopper 300 from below, it is possible to reliably clean the residual medicine adhered to the drop hopper 300 .

The cleaning of the drop hopper by the mechanisms (3), (4), (5), and (6) described above is performed when all the individual packages for one prescription are sealed, that is, the "one package distribution operation". ' is completed, the pile of powdered medicine on the disk 104 disappears, and the last package is moved from the position of the drop hopper 300 to the horizontal seal portion 209 and kept in a sealed state.

In this state, as shown in FIG. 12, the drop hopper 300 is placed in the upper position and the pressing member 328 and the suction member 329 are closed. create airflow. In this state, the compressor 402 is driven to blow compressed air from the air outlet 327 onto the inner wall of the upper hopper 301, blowing off the remaining medicine adhering to the corresponding portion. Since the compressed air flows from top to bottom, the air in which the powdered medicine is suspended is led to the dust collection blower 401 via the adsorbent 329 .

At this time, by performing (3) hitting the hopper and (6) opening and closing the shutter a plurality of times, a strong vibration force is applied to the drop hopper 300, and the residual medicine adhered to it is peeled off from the inner surface. The remaining medicine is also led out to the dust collection blower 401 via the adsorber 329 .

Since the residual drug attached in this way has mass, it tends to move in the direction of free fall. By creating an air flow in the direction of gravity from top to bottom, it is possible to efficiently remove and clean the residual medicine adhering to it, and clean the drop hopper 300 .

It should be noted that although it is not always necessary to blow compressed air from a compressor, it is possible to more reliably remove residual chemicals that have adhered by blowing compressed air.

Furthermore, although two sets of the disk part of the disk distribution part are provided, one set may be sufficient.

Moreover, as described above, the present invention can be applied not only to powdered medicine but also to a tablet packaging device.

As described in detail above, according to this embodiment, a synergistic effect of creating an air flow in the direction of gravity from top to bottom in the drop hopper and applying effective vibrations allows efficient adhesion. Removal and cleaning of residual medicine can be achieved.

By installing this drop hopper cleaning mechanism in the drug packaging apparatus, it is practically possible to operate continuously for about one day without manual cleaning. Furthermore, in the fully automatic medicine packaging device, instead of washing by hand once a day, by preparing a "washing cassette" containing baking soda in the medicine cassette and supplying this baking soda from a disk, Since a series of drug paths from the disk to the drop hopper can be washed, unmanned operation of the fully automatic drug packaging device for a long time can be realized.

As described in detail above, according to the present invention, medicine is divided and packaged in such a way that contamination of non-prescription substances is prevented by removing residual medicine adhering to the drop hopper that receives the medicine from the medicine supply section and delivers it to the medicine packaging section. Equipment can be provided.

Although several embodiments and variations of the invention have been described, these embodiments and variations are provided by way of example and are not intended to limit the scope of the invention. These novel embodiments and modifications can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and equivalents thereof.
