  In general, in a medicine packaging apparatus, powdered medicine or the like is once stored in a medicine supply container such as a hopper, and then supplied to the wrapping paper in accordance with the packaging timing and packaged.

  2. Description of the Related Art Conventionally, a medicine supply container is configured such that a lower end opening is opened and closed by an opening / closing plate so that medicine can be temporarily stored and then discharged at the timing of packaging.

  However, in the conventional chemical supply container, when an error occurs in the processing accuracy, particularly the processing accuracy and assembly accuracy of the opening / closing plate, a gap is generated between the lower end opening and the opening / closing plate. Adjustment work is required. However, if the error is due to the inclination of the axis of the opening / closing plate, adjustment work in the subsequent process cannot be performed and it is necessary to dispose of it. In addition, a gap may be generated between the lower end opening and the opening / closing plate due to wear or deterioration due to long-term use.

  Then, this invention makes it a subject to provide the chemical | medical agent supply container which can ensure the closed state by an opening-and-closing board.

As a means for solving the above problems, the present invention provides:
In the medicine supply container in which the opening and closing plate provided on the container body via the hinge member is rotated between the closed position for closing the opening formed in the container body and the open position for opening,

The container body is urged by the second urging means while being supported .

  With this configuration, even if the opening / closing plate is inclined with respect to the opening of the container body due to processing and assembly errors or wear or deterioration due to use, the shaft portion of the opening / closing plate moves at the support portion, and the biasing portion Thus, the opening / closing plate is pressed against the container main body, so that the closed state by the opening / closing plate is corrected, and the opening can be reliably closed.

  If the first urging means and the second urging means are made of the same member, it is preferable in that the structure is simplified and it can be manufactured at low cost.

  When the medicine remaining in the container body can be removed via the suction port by being driven in the container support member having a suction port connected to the suction device and driving the suction device, It is preferable in that it can be removed while preventing chemicals remaining on the surface from being scattered around.

  When the container main body is grounded, the chemical adhering to the container main body can be easily dropped by applying a force by striking or the like to the container main body, and the residual chemical can be easily removed. As a result, it is possible to prevent the residual chemical from being mixed into the chemical that passes through the container body next, and a complicated cleaning operation is not required.

  When a voltage is applied to the container body and the voltage value to be applied is changed, it is possible to prevent chemicals from adhering to the container body due to static electricity and to easily remove the remaining chemicals as described above. It is preferable in that it becomes possible.

  The voltage applied to the container body may be alternately switched in polarity between a positive electrode and a negative electrode, or may be alternately switched between a high potential and a low potential. In addition, the cycle time for replacement can be freely set.

  The opening / closing plate includes a variety of plane shapes such as a rectangle and an ellipse, and may have a curved surface shape. In short, it is only necessary that the opening can be closed. The material is not particularly limited, and if it is made of a flexible material, it is possible to further ensure the closed state of the opening / closing plate.

  The opening may be formed not only on the bottom surface of the container body but also on the side surface. In short, by closing the opening / closing plate, the medicine is temporarily stored in the container body and the opening / closing plate is opened. It is only necessary to be formed so that it can be discharged by doing so.

  The first urging means includes a coil spring, rubber, magnet, solenoid and the like. In short, what is necessary is just to automatically rotate the opening / closing plate to the closed position when the external force applied to the opening / closing plate is removed in the open position.

  In addition, the pivoting support means that the opening / closing plate is rotated about its shaft portion so that the opening / closing plate can be rotated between a closed position for closing the opening and another position for opening. Means that.

  Moreover, the said support so that a movement is possible means that it supports so that the axial part, ie, the inclination angle of an opening-and-closing plate, can be changed freely. For example, when the shaft portion of the opening / closing plate is supported by a vertically long insertion hole, the shaft portion can freely slide in each insertion hole, and the inclination angle of the opening / closing plate can be changed. Further, if the insertion hole is formed to have a larger inner diameter than the support shaft portion, the tilt angle of the shaft portion can be freely changed in any direction.

  The second urging means includes a coil spring, rubber, magnet, solenoid and the like. In short, any structure that can press the opening / closing plate against the container body in the closed position may be used.

  The vibration generating means includes a vibration motor and a solenoid. Any material can be used as long as it can apply vibration to the container body, such as low frequency to high frequency vibration or ultrasonic vibration. The container main body may be vibrated directly, may be vibrated indirectly via some member, or may be vibrated in a non-contact manner by an ultrasonic generator or the like.

  The suction device includes all devices that can suck and remove chemicals remaining in a container body such as a vacuum cleaner.

  The conductive material includes graphite powder, carbon powder, aluminum powder, and the like. The most preferred material is graphite powder, in particular polycrystalline powder aligned graphite.

  The fluororesin includes hexafluoropropylene-tetrafluoroethylene (FEP), alkyl vinyl ether-tetrafluoroethylene copolymer (PFA), polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene copolymer ( ETFE), polychlorotrifluoroethylene (PCTFE), ethylene-chlorotrifluoroethylene copolymer (ECTFE), polyvinylidene fluoride (PVDF), and the like.

  Moreover, polyimide, polybismaleimide, polyamideimide, etc. are contained in the said adhesive agent, ie, the adhesive agent used as a base material. In short, any material may be used as long as it prevents the coating material from peeling from the container body and can ground the static electricity generated on the surface of the coating material by having conductivity.

  The paint material includes an enamel paint material, an acrylic paint material, and the like.

  The heating means heating to room temperature or higher, and the heating method includes various methods such as infrared irradiation and a baking furnace.

  Moreover, it is preferable to increase the surface roughness by performing vapor deposition, sputtering and thermal spraying on the surface of the material before forming the base layer. The underlayer can be formed by (baking) coating.

  The coating material can be applied by spraying, brushing, transferring, screen printing, or the like. The most preferred method is spraying.

  Moreover, what is necessary is just to make it heat the said coating material at 100-400 degreeC. For example, baking is performed at 380 ° C. in the case of enamel paint, and 220 ° C. in the case of acrylic paint. Thereby, the surface strength and hardness of the coating material can be increased.

Moreover, as a method which does not form the said base layer and surface layer, the method of removing coating by machining, a file, etc. by masking and post-processing is contained.
Furthermore, the chemical supply container according to any one of the above,

The second bearing portion is supported, and the second bearing portion is configured to support the pivot portion of the opening / closing plate so as to be rotatable and movable, and the opening portion of the container body is biased by the opening / closing plate. Since the second urging means for closing is provided, the opening of the container body can be reliably closed with the opening / closing plate even if processing or assembly errors, or wear or deterioration due to use occur. It becomes possible.

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

  1 and 2 show a hopper according to this embodiment. The hopper includes a chemical supply container 1 and a container support member 2 that supports the chemical supply container 1.

  As shown in FIGS. 2 to 5, the chemical supply container 1 includes a container body 3, an opening / closing plate 4, and a hinge member 5.

  The container body 3 is formed by forming a conductive material such as DC12 aluminum die-casting or stainless steel into a pyramid shape whose sectional area gradually decreases downward. The container body 3 is partitioned into a tablet supply passage 6 and a powder supply passage 7. A closing piece 8 protrudes obliquely downward from the upper opening edge of the container body 3. Further, as will be described later, the container body 3 is subjected to a surface treatment so that powders and the like are less likely to adhere (see paragraphs 0049 to 0052). However, non-processing parts 9a and 9b (see FIG. 1) that are not subjected to surface treatment are formed on a part of the container body 3. The non-processing part 9 a is formed at the edge of the lower end opening 7 a of the container body 3. The non-processing portion 9b is formed on the side surface of the container body 3. The non-processing portion 9b is given an impact force by a solenoid or the like, and the container body 3 is vibrated to drop the powder adhering to the inner surface. It can be made to.

  The opening / closing plate 4 is a plate-like body that opens and closes the lower end opening 7a of the powder supply passage 7 of the container body 3, and a bearing portion 4a is formed on one end side. A shaft portion 4b that passes through an insertion hole 18 of the second bearing portion 12 to be described later is attached to the bearing portion 4a.

  The hinge member 5 includes a first bearing portion 10 that is integrated with the side surface of the container body 3, a drive shaft portion 11 that is rotatably supported by the first bearing portion 10, and is rotatable about the drive shaft portion 11. And a second bearing portion 12 supported by the first bearing portion 12.

  The first bearing portion 10 has a support wall 14 projecting from a rectangular frame 13 at a predetermined interval. A through hole 14 a is formed at the tip of each support wall 14. A cylindrical ring 15 is press-fitted into each through hole 14a so that the drive shaft 11 can be rotatably supported.

  The drive shaft portion 11 is bent and extends from the support shaft portion 16 rotatably supported through a ring 15 in a through hole 14a formed in the support wall 14 of the first bearing portion 10. It is comprised with the drive part 17. FIG. The drive unit 17 is pressed by a solenoid or the like (not shown). By pressing the drive unit 17, the drive shaft unit 11 rotates about the support shaft unit 16.

  The second bearing portion 12 includes an insertion hole 18 through which the support shaft portion 16 is inserted, and a support wall 19 that protrudes at a predetermined interval and is formed with a through hole 19a, like the bearing portion. The insertion hole 18 is formed in a vertically long shape so that the inserted support shaft portion 16 can move. However, the shape of the insertion hole 18 is not limited to a vertically long shape, and may simply have a larger inner diameter than that of the support shaft portion 16, as long as the support shaft portion 16 is freely movable. Moreover, the 2nd bearing part 12 is formed with the guide hole (not shown) in two places, and the auxiliary | assistant spring 20 is each arrange | positioned. The auxiliary spring 20 presses the opening / closing plate 4. However, instead of the auxiliary spring 20, a rubber, a magnet, a solenoid, an air cylinder, or the like may be used. The second bearing portion 12 is non-rotatably attached to the support shaft portion 16 with screws or the like.

  In addition to the second bearing portion 12, a coil spring 21 and a spring support body 22 are attached to the support shaft portion 16 of the drive shaft portion 11. The coil spring 21 is extended so that one end thereof is in pressure contact with the bearing portion, and the other end is annular and is screwed to the second bearing portion 12. The spring support 22 is formed with a through hole 22 a through which the support shaft portion 16 passes and a screw hole 22 b for screwing the coil spring 21. The spring support 22 is fixed to the support shaft 16 so as not to rotate by screws or the like.

  The container support member 2 includes a container housing portion 23 in which the medicine supply container 1 is mounted, and a guide portion 24 that guides the medicine supplied from the medicine supply container 1 to a packaging device (not shown).

  The container housing portion 23 has suction ports 25 formed at both end surfaces. Then, by driving a suction device (not shown), it is possible to remove chemicals remaining in the hopper through the suction port 25. Further, the container housing portion 23 is formed with a first cutout portion 26 on the front wall where the closing piece 8 of the medicine supply container 1 is located. Moreover, the container accommodating part 23 is formed with a second notch 27 on the back wall where the bearing part of the chemical supply container 1 is exposed. A guide piece 28 that protrudes outward and guides the drive shaft 11 is provided on the lower edge of the second cutout 27. The container housing portion 23 is grounded so that charging of the container body 3 can be prevented through a contact portion (conduction portion) with the container body 3.

  The guide portion 24 has a configuration in which the tip is separated into a substantially V shape so that the medicine can be smoothly supplied to the wrapping paper prepared in a folded state by a packaging device (not shown). The chemical supply container 1 accommodated in the container accommodating portion 23 of the container support member 2 is detachably fixed to the container accommodating portion 23 with screws 30 using a fixing bracket 29.

  Then, the surface treatment of the said container main body 3 is demonstrated. The surface treatment here is performed in the order of degreasing treatment, base treatment, and coating treatment. Each process is described below.

  In the degreasing treatment, it is carried out by either a baking degreasing method or a chemical cleaning method. In the baking degreasing method, after baking at a melting limit temperature of 200 ° C. or higher, the oxide film formed on the surface is subjected to sand shot, barrel polishing, or blasting (using a steel grid # 30 with a blast machine). Remove. In the chemical cleaning method, for example, cleaning is performed with trichlene, thinner, Freon cleaning liquid, or the like. Moreover, what is necessary is just to etch the surface by acid or alkali washing | cleaning, when forming the container main body 3 with an aluminum alloy. In this embodiment, after baking at 380 ° C. and naturally cooling for 2 hours, the oxide film was removed by sand shot.

In the base treatment, a base layer having a two-layer structure is formed on the surface of the degreased container body 3 with a base material. As the base material, for example, a mixture of a fluorine-based resin and graphite in an adhesive can be used. As the adhesive, polyimide, polybismaleimide, polyamideimide, aromatic polyamide, or the like can be used. One or more types may be selected from these. As the fluororesin, a tetrafluoroethylene homopolymer or a modified tetrafluoroethylene polymer containing a copolymer of tetrafluoroethylene and a fluorine-containing α-olefin can be used. What is necessary is just to make it contain fluorine-containing alpha-olefin content in an upper layer compared with the lower layer of a base layer. Graphite can use carbon molecules that are crystalline (multi-bonded) and have a particle size of several to several hundred microns. In this case, the mixing ratio of the graphite with respect to the adhesive and the fluorine-based resin may be 6 to 70%, and preferably about 30%. As a result, the surface resistance of the underlayer can be made 10 ⁷ Ω (ohms) or less. In the present embodiment, the base layer having a thickness of 10 to 30 μm is formed by drying and cooling at 120 ° C. for 30 minutes. However, the non-processed portions 9a and 9b are masked with a chemical substance that is flammable or vaporized at a high temperature in addition to tape, brazing, and sealing so that the base treatment is not performed.

  In the coating process, a surface layer is formed on the surface of the base layer with a coating material. As the coating material, for example, an enamel paint mainly composed of varnish and a mixture of an adhesive, a fluorine-based resin, and graphite can be used in the same manner as the base layer. The surface layer is formed with a coating material by coating with an air spray gun until the thickness reaches 15 to 20 μm, dried at 100 ° C. for 20 minutes, and then baked at 380 ° C. for 30 minutes. This was repeated until the thickness reached 70 μm (here, 3 times). The masking applied to the non-processing parts 9a and 9b is removed after the coating process.

  Next, the operation of the hopper will be described.

  In the medicine supply container 1, in the initial state, as shown in FIG. 6A, the lower end opening of the powder supply passage 7 is closed by the opening / closing plate 4 by the biasing force of the coil spring 21. In this initial state, one powder of powder is supplied to the powder supply passage 7 from a powder supply device (not shown) and is temporarily stored here.

  Then, by exciting a solenoid (not shown) and pressing the drive unit 17 of the drive shaft unit 11, the drive shaft unit 11 is rotated about the support shaft unit 16 as shown in FIG. Thereby, the opening / closing plate 4 opens the lower end opening of the powder supply passage 7, and the stored powder falls. Since the chemical supply container 1 is grounded and the surface treatment is applied to the inner surface, it is difficult for the powder to adhere. For this reason, the powder in the powder supply passage 7 falls smoothly into a packaging device (not shown).

  Table 1 shows the results of comparison of the adhesion status of each reagent between the chemical supply container 1 subjected to the surface treatment and the chemical supply container 1 subjected to the same surface treatment. Here, EP-FCP means antistatic treatment fluororesin fired coating which is a surface treatment according to the present invention, and SPC means hard alumite fluororesin adsorption treatment which is a conventional surface treatment. Moreover, the said chemical | medical agent supply container 1 used the thing made from die-casting. Further, as experimental conditions, as shown in FIG. 8, the medicine supply container 1 is turned sideways, and each reagent is sequentially supplied in a predetermined amount (a quantity that can be supplied according to each reagent). Thereafter, as shown in FIG. 9A and FIG. 9B, it was rotated 90 degrees to a position in a normal use state, and the remaining amount of the reagent was visually observed. As a result, in the case of using calcium lactate as a reagent, in the chemical supply container 1 subjected to the surface treatment shown in FIG. 9A, the amount of the remaining medicine was small, whereas the conventional surface treatment shown in FIG. 9B was performed. In the applied chemical supply container 1, the remaining drug was larger than that in FIG. 9A.

(In Table 1, ◎: None, ○: Slight, △: Small amount, ▲: Slightly more)

  At this time, an impact force is applied to the non-processing section 9 of the container body 3 by driving a solenoid (not shown). For this reason, even if the powder adheres to the inner surface of the powder supply passage 7, it is surely dropped into the packaging device. In each reagent in Table 1, the amount of the remaining drug was completely lost.

  When the supply of powder to the packaging device is completed in this way, the solenoid is demagnetized and the pressing force applied to the drive unit 17 is released. Thereby, the drive shaft part 11 rotates around the support shaft part 16 according to the urging force of the coil spring 21, and directs the opening / closing plate 4 toward the lower end opening part of the powder supply passage 7. In this case, the support shaft portion 16 can move through a vertically long insertion hole 18 formed in the second bearing portion 12. The opening / closing plate 4 is urged by the auxiliary spring 20 so as to be separated from the second bearing portion 12. Therefore, even if the opening / closing plate 4 is inclined with respect to the lower end opening of the powder supply passage 7 due to variations in processing accuracy and assembly errors, the support shaft 16 is allowed to be inclined in the insertion hole 18, and the auxiliary spring 20. Since the opening / closing plate 4 is pressed against the lower end opening, the closed state can be ensured. Further, even if the opening / closing plate 4 or the lower end opening is worn due to long-term use or the rotation of the opening / closing plate 4 is displaced, the opening / closing plate 18 is corrected by the action of the insertion hole 18 and the auxiliary spring 20. The closed state of the lower end opening by 4 can be ensured.

  In the above-described embodiment, the tablet supply passage 6 and the powder supply passage 7 are formed in the container body 3, but a configuration including only the powder supply passage 7 may be employed. Moreover, it is good also as a structure by which multiple container main bodies 3 are arranged in parallel, The quantity does not matter.

  Moreover, in the said embodiment, static electricity was removed by grounding the container main body 3, However, It is also possible to remove by applying a voltage. For example, the positive electrode and the negative electrode may be applied alternately. Alternatively, a high potential (20V) and a low potential (5V) may be applied alternately. In this case, as the cycle time for changing the potential, for example, the high potential may be 10 seconds and the low potential may be 3 seconds.

  Moreover, in the said embodiment, although the coil spring 21 was used as an urging | biasing means and the auxiliary spring 20 was used as an urging | biasing part, as shown in FIG. That is, one end 21 a of the coil spring 21 is pressed against the frame 13, and the other end 21 b is pressed against the opening / closing plate 4. As a result, not only the opening 7a is automatically closed by the opening / closing plate 4 from FIG. 7 (b) to FIG. 7 (a) but also the inclination of the opening / closing plate 4 at the closed position can be corrected only by the coil spring 21. It becomes possible.
