Description

  More particularly, the present invention relates to a powder discharge device that discharges powder to a powder packaging device that is a part of the powder distribution device, and a powder container that is used together with the powder discharge device. The present invention relates to a powder storage container and a powder discharge device that can prevent dispensing and accurately measure powder and discharge it to a powder packaging device.

  With regard to powder dispensing operations, in a conventional device, a pharmacist measures the amount of one prescription for a predetermined drug in advance on a weighing table, and then puts this into the device, so that the distribution device can reduce the amount to a predetermined number of packages. The powder was divided and the powdered powder was individually packaged by a packaging machine. On the other hand, in recent years, in order to reduce the burden of pre-measurement work by a pharmacist, an apparatus and a system that can automatically perform measurement for one prescription by the apparatus have been put into practical use.

  For example, Patent Document 1 discloses a medicine dispensing device that takes out a predetermined amount of powder from a powder storage container, divides it into a predetermined number, and individually wraps and discharges the powder. A container for storing a plurality of powder storage containers, having a discharge port portion that serves as a discharge port for discharging the stored powder, and for storing a plurality of powder storage containers; A moving device is provided, the container moving device can perform an operation of taking out a predetermined powder storage container from the container storage device and placing it on the container mounting device, and from the powder storage container mounted on the container mounting device Discharging the powder is disclosed.

  Here, the powder storage container is stored vertically in the container storage device (the discharge port is in the vertical direction of the upper surface), and when it is moved by a container moving device such as a robot arm, its posture is set horizontally (the discharge port is (The horizontal direction of the bottom surface) and placed on the container placing device in that state.

  The reason for changing the posture of the powder storage container in this way is that it is desirable to install it horizontally in order to discharge the powder from the powder storage container, while the storage device is preferably placed vertically because of the occupied area. When storing in the storage device, the powder discharge port is turned upward so that the powder is drawn below the powder storage container (distant from the discharge port). It is said that the powder can be prevented from spilling when it is placed on the mounting device and immediately before the discharge port is opened and discharged.

  However, each of these devices has a system in which containers containing a large number of drugs are arranged in advance on a shelf, and this is moved to a measuring unit using means such as an articulated robot or articulated chain movement. It was large and expensive.

  In general, small dispensing pharmacies have a small space, so it is not possible to install a large device. For dispensing, it is necessary to prescribe not only powder but also tablets. There is a problem that it is not possible to install a packaging machine, or even if an expensive device is installed, there is a problem that the operating rate is low and it is difficult to make a profit.

  In addition, when realizing a small and simple device, it is assumed that the powder storage container is manually moved (transported) instead of a large-scale means such as an articulated robot or moving an articulated chain. A method for preventing powder from spilling out without changing the posture of the powder storage container is required.

  Here, the powder container must always have a discharge port for releasing the drug. Normally, the discharge port is closed, moved and detached, and then attached to the powder discharge device. After opening the door of the outlet, the drug is discharged and measured, and after completion, the door of the outlet is closed again, and then it is detached and moved. At that time, there are two problems as described below.

  FIG. 12 is an explanatory view of a conventional powder container. The powder storage container 1 stores the powder P therein. As shown in FIG. 12 (a), a shielding plate 3 rotatably supported by the shaft 2 is provided on the left side of the powder storage container 1, and the discharge port 4 for the medicine P is closed.

  FIG.12 (b) has shown the state which opened the shielding board 3 of the discharge port 4 of the powder storage container 1 by the means which is not shown in figure. When the shielding plate 3 is opened and driven by another vibration means or the like, the medicine P can fall from the discharge port 4 in the direction of the arrow 5. The first problem is that the crest of the medicine P at the tip of the discharge port 4 collapses slightly and falls like P1, just by opening the shielding plate 3 without applying vibration drive. .

  Table 7 in the paper “Relationship between packaging accuracy and powder physical properties by powder pre-former” described in Non-Patent Document 1. The measurement results of physical properties of each powder and granule (reproduced in FIG. 13) show the repose angle and collapse angle of typical drugs.

  The maximum angle of the slope that keeps its stability without collapsing spontaneously when powdered fluid such as powder is stacked is called the “rest angle”. On the other hand, the “collapse angle” indicates an angle when the powder deposits that are stationary at the repose angle are collapsed by giving a certain impact.

  Here, if the angle between the shielding plate and the bottom surface of the powder storage container is larger than the angle of repose (or the collapse angle), if powder is gathered in contact with the shielding plate, If the shield is opened, powder may spill out.

  Next, the second problem will be described. FIG.12 (c) has shown the state which closed the shielding board 3 of the discharge port 4 of the powder storage container 1 by the means which is not shown in figure. Here, although it is drawn schematically schematically, some powder P2 may be sandwiched between the shielding plate 3 and the discharge port 4. As a result, the shielding plate 3 cannot be sealed and a gap is formed.

  The shape of powder is diverse, but the gap is large when a large particle size called a granule is sandwiched. In this state, when the discharge port 4 is turned slightly downward, the medicine further spills out.

  Even if the amount of unnecessary powder spillage due to these two problems is small, it is difficult to manage where the spilled powder falls and adheres, and as a result other drugs that are not intended There is a risk that it may lead to contamination.

Japanese Patent No. 595471

Hospital pharmacy Vol. 19, no. 2 (1993)

  In view of the above problems, the problem to be solved is to prevent the powder from spilling out from the powder container when providing a compact, space-saving, low-price powder dispenser with automatic weighing function. It is a difficult point.

  In order to solve the above-mentioned problems, a first aspect of the present invention is a powder storage container that can be stored to release a powder and can be attached to a powder discharge device, and a discharge port that discharges the powder. And a shielding portion that shields the discharge port, and an additional shielding portion that further shields the discharge port.

  If it does in this way, since it will have the shielding part which shields a discharge port, even if it moves without changing the attitude | position of a powder storage container horizontally, it can prevent a powder from spilling out. .

  In addition, even if the powder is caught in the shielding part, the additional shielding part can prevent the powder from spilling out of the powder container.

  Alternatively, in order to solve the above-mentioned problem, the second aspect of the present invention is a powder storage container that can be stored to release a powder and can be attached to a powder discharge device, and is a waste container that discharges the powder. The angle between the outlet and the shielding part that shields the discharge port, and the angle between the shielding surface of the shielding part and the bottom surface in the vicinity of the shielding part is an angle at which the powder does not collapse in a stationary state when the shielding part is opened. It is characterized by the following.

  Here, the angle at which the powder does not collapse in a stationary state is generally called the angle of repose and is determined by the material and particle size of the powder, and if the angle of the shielding part, for example, the flat plate for shielding is less than that Even if the flat plate for shielding is opened by means such as turning, the powder does not spill out as it is.

  Furthermore, in 2nd this invention, the center part of the bottom part of a powdered medicine container is horizontal, and the front (discharge port side) and back (opposite side to a discharge port) incline slightly upwards, It is characterized by the above-mentioned. Also good.

  In this way, it is possible to prevent unintentional spilling out of the powder before release and to release it efficiently at the time of release.

  Alternatively, in order to solve the above-mentioned problem, the third aspect of the present invention is a powder container that can be accommodated for releasing a powder and can be attached to the powder discharge device, wherein the powder is discharged from the powder. An opening, a shielding portion that shields the discharge port, and an additional shielding portion that further shields the discharge port, and the angle between the shielding surface of the shielding portion and the bottom surface in the vicinity of the shielding portion opens the shielding portion. The angle is equal to or less than the angle at which the powder does not collapse in a stationary state.

  If it does in this way, the effect of both the double shielding part mentioned above and the angle of a shielding part will be acquired repeatedly.

  In the powder container of the first invention or the third invention, the shielding portion is opened and closed by electrical control, and the additional shielding portion is mechanically opened and closed by being attached to and detached from the powder discharge device. It is good also as a feature.

  In this way, when attached to the powder discharge device, the additional shielding part is first mechanically opened, and then the shielding part is electrically opened. Since the shielding parts are opened in this order, it is possible to further prevent powder from spilling out.

  In addition, since the additional shielding portion is mechanically opened and closed, a control mechanism and a drive mechanism are not required, and a low-cost configuration can be realized.

  It should be noted that the order of opening the shielding part and the additional shielding part may be more effective depending on the structure of the apparatus, etc., even if it is the reverse or the same as described above.

  The present invention also includes a powder storage container mounting portion to which the powder storage container described above is mounted, a shielding portion opening / closing section for opening and closing the shield portion of the powder storage container, the powder storage container, and the container. It may be an aspect of a powder discharge device including a measuring unit that measures the weight of the powder and a powder discharge unit that discharges the powder from the discharge port of the powder container.

  If it does in this way, a powder storage container will be attached to the powder storage container attachment part of a powder discharge device, and the shielding part will be opened by the shielding part opening and closing part provided in the powder discharge device side, for example, powder discharge by means, such as vibration The powder in the powder storage container is released by the part, and the weight of the released powder can be known by measuring the weight of the powder storage container attached to the powder storage container mounting part. A series of subsequent automation can be realized.

  That is, even if the powder container is placed in a horizontal position and is manually transported and attached to the powder discharge device, the opening and closing part of the shielding part is built in the powder discharge device, so that the powder spills out. Simple automation can be realized while preventing the above.

  If the automatic transportation means such as a multi-joint robot is used and the automatic transportation means side has an opening / closing means for the shielding part, the shielding part is opened at the timing when the powder storage container is installed in the powder discharge device. In this case, there is a risk that spillage may occur due to external force such as vibration. However, according to the present invention, since the shielding part opening / closing part is provided on the powder discharge device side, After being installed in the discharge device, the shielding portion can be opened without any external force and the risk of spillage can be reduced.

  Further, the present invention is an aspect of a powder wrapping machine having a powder packaging container for distributing and packaging a powder discharged from the powder discharge device in addition to the powder container and the powder discharge device described above. There may be.

  In this way, it is possible to automate consistently up to powder packaging.

  The present invention is not limited to powder storage containers having the characteristics described so far, but any powder storage container having a discharge port for discharging powder and a shielding part for shielding the discharge port. Even if it exists, the powder storage container attaching part to which it is attached, the shielding part opening and closing part for opening and closing the shielding part of the powder storage container, and the measuring part for measuring the weight of the powder storage container and the stored powder And the aspect of a powder discharge | release apparatus which has a powder discharge | release part which discharges a powder from the said discharge port of the said powder storage container may be sufficient.

  According to this, the powder storage container is not particularly limited, and even when the powder storage container is manually transported and attached to the powder discharge device, since the shielding portion opening and closing part is built in the powder discharge device, Simple automation can be achieved while preventing powder spillage.

  Furthermore, the present invention is not limited to the powder storage container having the characteristics described so far, in addition to the powder discharge container that has a discharge port that discharges powder and a shielding part that shields the discharge port, and the powder discharge device, It may be an embodiment of a powder packaging machine having a powder packaging device that distributes and packs the powder discharged from the powder discharge device.

  In this way, it is possible to automate consistently up to powder packaging.

  According to the powder container, the powder discharge device, and the powder dispenser of the present invention, it is possible to provide a powder dispenser with a small, space-saving, low-price automatic weighing function, especially during storage, transportation, and The powder can be prevented from spilling out of the powder storage container when set in the powder discharge device.

It is a front view of the powder medicine packaging machine 100 which concerns on a form.

  The powder dispensing machine 100 includes a powder storage container 200 that stores a powder to be packaged, a powder release device 300 that attaches the powder storage container 200 and releases the powder therein, and distributes and packs the released powder. And a powder packaging apparatus 400.

  However, the separation of these devices is not limited to this, and any separation may be used as long as an equivalent function can be exhibited.

  Each component will be described below.

<Powder storage container 200>
An embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a perspective view of a powder storage container 200 according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view of the powder storage container 200 according to an embodiment of the present invention.

  The powder storage container 200 is a substantially rectangular parallelepiped box shape having a bottom surface, and the longitudinal direction is set to be a substantially horizontal direction. This posture is set horizontally.

  The powder storage container 200 has an upper lid 201 on the upper side, a powder discharge port 202 on the lower side surface, a shielding part (shielding plate) 203 that shields the discharge port 202 at the outlet part of the discharge port 202, and a shielding part 203 rotatably. The shielding part rotating shaft 204, the additional shielding part 205 provided on the outer part of the container with respect to the shielding part 203, the additional shielding part turning shaft 106 for rotatably holding the additional shielding part 205, the shielding part 203, and the addition. A plate spring 207 urging the shielding part 205 in the closing direction, a push plate 208 provided at the lower end of the shielding part 203 and capable of rotating the shielding part 203 in the opening direction when pressed, and an iron plate made of a magnetic material on the outside of the bottom surface 209.

  The means for urging in the closing direction is not limited to the leaf spring, and may be an elastic body such as a coil spring or an inertial mass body. Further, urging the shielding part 203 and the additional shielding part 205 with the common leaf spring 207 has a great effect of reducing the number of parts, but separate urging means may be provided for each shielding part. Depending on the mass of the shielding part, the opening / closing timing, etc., there may be cases where different ones are advantageous.

  As shown in the figure, the bottom of the powder container 200 placed on a horizontal plane is horizontal at the center, and the front (discharge port side) and rear (opposite the discharge port) are slightly inclined upward. It has a pan-bottom shape. This prevents the stored powder from getting too close to the discharge port 202 to prevent the powder from leaking out, and prevents it from collecting too much backward to facilitate discharge of the stored powder. It is intended.

  However, the bottom surface may be a flat surface that is horizontal or non-horizontal. Depending on the nature of the powder, the method of handling the powder container, etc., it may be advantageous to have a uniform flat surface that is easy to process. Even when only one of the front and rear is inclined slightly upward, the above-described effects can be obtained to some extent.

  In addition, an angle A formed by the bottom surface near the discharge port 202 of the powder storage container 200 and the shielding portion 203 is about 30 degrees. This is because, as will be described later, when the powder storage container 200 is placed on the powder discharger, the bottom surface in the vicinity of the discharge port 202 is horizontally placed. The angle formed is equal to or less than an angle (referred to as an angle of repose) at which the powder does not collapse in a stationary state when the shielding portion 203 is opened.

  FIG. 13 is an explanatory diagram of the angle of repose and the collapse angle according to the present invention. Here, for example, the angle of repose is 43.5-54.5 degrees for powdered powder and 31.0-- for fine particles. 34.5 degrees and 36.0-36.5 degrees for granules.

  Therefore, if the angle A is 30 degrees, almost any powder is smaller than the angle of repose, and collapse of the powder in a stationary state can be prevented.

  However, depending on the powder used, a larger angle (35 degrees, 40 degrees, etc.) may be acceptable, or a smaller angle (25 degrees) in consideration of the collapse angle (13.0-32.0 degrees). , 20 degrees, 15 degrees, etc.) may be effective.

  In this embodiment, the shielding part 203 is a plate-like thing which has a rotation center above the discharge port 202, and may be called a shielding board. However, the shape is not limited to a plate shape, and may be a rod shape, a column shape, or other shapes, and at least a portion that shields the discharge port 202 may be a flat surface. Further, the opening / closing method is not limited to the plate-shaped end portion as the rotation center, and various shapes such as a slide type and a double door can be considered.

<Powder release device 300>
An embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a cross-sectional view of a powder discharge device 300 according to an embodiment of the present invention, and FIG. 7 is a perspective view showing a relationship between the powder discharge device 300 and the powder container 200 according to an embodiment of the present invention. .

  The powder discharge device 300 includes a fixing plate 303, a fixture 304, a measuring unit 305, a vibration base 306, a leaf spring 307, a powder storage container mounting unit 308, a first electromagnet 309, an iron material 310, a second electromagnet 311, and a shielding unit. An opening / closing part 312 is provided.

  The fixing plate 303 holds the entire powder discharge device 300 and is firmly fixed in the housing of the powder packaging machine 100.

  The fixing tool 304 is provided on the fixing plate 303 with a leg portion and a flat plate portion supported by the leg portion, and an element of the apparatus is fixed thereon.

  The weighing unit 305 is installed on the flat plate of the fixture 304, and the vibration base 306 is placed on the upper surface of the weighing unit 305. Therefore, when the total mass mounted on the vibration base 306 is loaded on the weighing unit 305, the mass is increased. Measurement can be performed.

  The weighing unit 305 is preferably a platform scale, but is not limited thereto, and may be any unit that can measure the weight of a load cell or the like placed on top of the weighing unit.

  The vibration base 306 includes a leg portion that is inclined with a low exit direction (front) of the powder and an inclined flat plate portion that is supported by the leg portion.

  There are two sets of leaf springs 307, which extend upward from the front and rear of the inclined flat plate portion of the vibration base 306 to hold the powder storage container mounting portion 308.

  The first electromagnet 309 is fixed to the vibration base 306, and on the other hand, the iron material 310 having magnetism is disposed in the powder storage container mounting portion 308 with a slight gap therebetween. As a result, when an alternating electrical waveform is input to the first electromagnet 309, the iron material 310 exhibits a vibrational behavior such as being pulled toward or away from the first electromagnet 309.

  As a result, the powder storage container mounting portion 308 is attached to the vibration base 306 via the leaf spring 307, so that the powder storage container mounting portion 308 as a whole performs vibration in which the vertical and horizontal directions in the drawing are combined. Can do.

  These iron bases 310 of the vibration base 306, the first electromagnet 309, the leaf spring 307, and the powder storage container mounting part 308 are collectively referred to as a powder discharge part 320.

  However, the configuration of the powder discharger 320 is not limited to that using an electromagnet, and may generate vibration by a piezoelectric element as long as the powder can be discharged little by little, or is not limited to vibration and is driven by a helical screw. Or other than that.

  The second electromagnet 311 is provided in a state where the magnetized surface is exposed on the upper surface of the powder storage container mounting portion 308. This can adsorb | suck the iron plate 209 attached to the bottom face of the powder storage container 200 by electricity supply, and can hold the powder storage container 200 fixed to the powder storage container mounting part 308.

  The shielding part opening / closing part 312 is a direct acting electromagnetic solenoid, is attached to the lower surface of the powder storage container mounting part 308, and pushes the push plate 208 provided on the shielding part 203 of the powder storage container 200, thereby shielding the shield part 203. Has the function of opening

  The shielding unit opening / closing unit 312 is not limited to a mechanism including a direct acting electromagnetic solenoid and a shielding plate-side push plate 208. For example, a lead screw is directly connected to a motor to rotate the motor as a linear motion. Various operations such as pushing 208, using a push plate, or using various drive sources provided on the powder discharger 300 side without using a push plate, and rotating the shield 203 by a link mechanism, etc. A known operating mechanism may be used.

<Powder packing device>
An embodiment of the present invention will be described with reference to the drawings. FIG. 8 is a perspective view of the disk distribution unit 401 of the powder packaging apparatus 400 according to one embodiment of the present invention.

  The powder packaging device 400 includes a disk distribution unit 401 that receives and distributes the powder discharged from the powder discharge device 300 on the disk 402, a hopper chute 403 that drops the powder distributed by the disk distribution unit 401 downward, and a hopper A wrapping paper is disposed at the exit of the chute 403, and the wrapping paper has a powder packaging part 404 that encloses and packs the powder.

  The disc distribution unit 401 includes two sets of left and right disc distribution units 401A and right disc distribution units 401B. Since two powder discharge devices 300 are arranged for each of them, four powder discharge devices 300 are arranged in one disk distribution unit 401. Furthermore, a plurality of such disk distribution units 401 may be arranged in the powder medicine packaging machine 100 as a whole.

  In addition, these arrangement | positioning number is an illustration, and may be less than this or may be many. What is necessary is just to select suitably according to a use purpose.

  The cut powder is dropped downward through the hopper / chute 403, and a powder packaging unit 404 is provided that can enclose the powder in the wrapping paper arranged corresponding to the outlet of the hopper / chute 403. Yes.

  Next, an operation according to an embodiment of the present invention having such a configuration will be described. FIG. 9 is a perspective view showing a state in which the powder storage container 200 according to one embodiment of the present invention is attached to or removed from the powder discharge device 300. FIG. 10 is a cross-sectional view showing the operation in the vicinity of the discharge port 202 of the powder storage container 200 in the mounting and removal operations of the powder storage container 200 according to one embodiment of the present invention.

  In another place, the individual powder P is opened by filling the inside of the powder storage container 200 by opening the upper lid 201, and the upper lid 201 is closed again, and then carried by hand. At this time, since the shielding portion 203, “closed”, and additional shielding portion 205 “closed” as shown in FIGS. 9A and 10A, the discharge port 202 is double-closed. It doesn't spill even if it is operated roughly by hand.

  Next, the powder storage container 200 is a part of the powder storage container mounting portion 308 of the powder discharge device 300 and the container mounting guide body 313 constituting the upper surface is used as a guide by the operator to make the powder storage container 200 a powder. It is attached to the container attachment part 308.

  In addition, as shown to Fig.10 (a), the angle A which the bottom face which becomes horizontal when attached to the powder discharge | release apparatus 300 in the vicinity of the discharge port 202, and the shielding surface of the shielding part 203 becomes below a repose angle. Therefore, even if the shielding part 203 is opened after being attached to the powder discharge device 300, there is little risk of powder spilling out.

  At this time, the protrusions 210 provided on the left and right sides of the additional shielding part 205 are pressed against the inclined surface part 314 of the container mounting guide body 313, so that the additional shielding part 205 is in an open state. At this time, the shielding unit 203 is “closed” and the additional shielding unit 205 is “open” in FIG.

  Next, when the input device (not shown) notifies the device of “setting completion” of the powder storage container 200, the second electromagnet 311 of the powder discharge device 300 is driven by the control unit (not shown), and on the bottom surface of the powder storage container 200. By adsorbing the attached iron plate 209, the powder storage container 200 is firmly fixed to the powder discharge device 300.

  This state is the standby state of the powder discharge device 300. In this state, the powder storage container 200 is in a state where the front (discharge port side) is inclined slightly lower, and the bottom surface in the vicinity of the shielding part 203 is horizontal. Therefore, the angle formed by the shielding surface of the shielding portion 203 and the bottom surface in the vicinity of the shielding portion 203 is a repose angle, and when the shielding portion 203 is gently opened, the powder does not spill by itself.

  Next, when there is an instruction to release a predetermined amount of the drug P from the powder storage container 200, the shielding part opening / closing part 312 is first driven, thereby opening the shielding part 203 of the powder storage container 200. At this time, the shielding portion 203 “open” and the additional shielding portion 205 “open” in FIG. 9C and FIG.

  Thereafter, the disk 402 of the disk distribution unit 401 of the powder packaging apparatus 400 having the surface disposed below the powder discharge port 202 is rotated at a constant speed, and then the first electromagnet 314 is driven, When the base 313 is vibrated, the powder storage container 200 coupled to the base 313 also vibrates, so that the powder accumulates in a donut shape from the powder discharge port 202 on the rotating disk 402.

  At this time, the total mass on the first base is continuously weighed by the weighing unit 305, and when the predetermined mass is reached (for example, the amount specified in the prescription), that is, the predetermined amount is released. When the predetermined mass is reduced, the vibration of the electromagnet 314 is stopped and the rotation of the disk 402 is also stopped.

  At the same time or after some time, when the driving of the shielding portion opening / closing portion 312 is released, the shielding portion 203 of the discharge port 202 is closed.

  Thus, even if a disturbance such as vibration is applied from the outside, the powder P near the discharge port 202 does not spill out.

  Next, the powder 402 formed in a donut shape on the disk 402 of the disk distribution unit 401 is stopped by rotating the disk 402 by a predetermined angle, and the number of circumferential divisions (for example, equal to 10) indicated by the control unit And is divided into one package by cutting out at a cut-out section (not shown).

  The cut out powder falls downward through the hopper / chute 403, and the medicine P is enclosed in the wrapping paper of the powder packaging part 404 provided at the outlet of the hopper / chute 403. In this way, for example, the packaging state of 10 packages of 1 prescription is completed.

  In addition, when a powder storage container 200 is removed after a series of processes are complete | finished, operation opposite to the time of attachment is performed. Then, the shielding part 203 and the additional shielding part 205 are a leaf spring 207 (shown in FIGS. 4 and 9C), which is a common biasing means in the closing direction (not shown in FIG. 9A). As a result, the discharge port 202 is double-shielded (closed) and can be moved to another place without worrying about spillage.

  FIG. 11 is an explanatory diagram of a shielding part 503 of a powder storage container according to another embodiment of the present invention. The discharge port 502 of the powder storage container is provided with a shielding part 503.

  The shielding portion 503 is provided so as to have an angle (for example, about 30 degrees) that is equal to or less than the repose angle of the powder when the bottom of the powder container near the discharge port 502 is horizontally installed.

  The linear motion bearing 505 fixed to the shielding portion 503 is slid on an axis parallel to the shielding surface of the shielding portion 503 by a drive mechanism (not shown).

  The shielding unit 503 can be operated along the end surface of the discharge port 502 by a driving unit (not shown), so that the discharge port 502 can be opened and closed. FIG. 11A shows the “closed” state, and FIG. 11B shows the “open” state.

  Since such an operation is possible, even when the medicine P2 adheres to the end face of the discharge port 502 due to static electricity or the like as shown in FIG. 11C, the medicine is closed by the closing operation of the shielding portion 503. P2 is pushed out, and there is no gap between the shielding portion 503 and the discharge port 502 when the drug is closed.

  In the above description, it has been described as preventing powder spillage when handling the powder container manually, but even if it is automatically performed by a robot, etc. The present invention is effective and has an advantage that the precision of control of a robot or the like can be reduced.

  In the above description, the portion attracted by the electromagnet has been described as an iron plate or iron material that is a magnetic material. However, the material is not limited to iron as long as it is a substance that can be attracted by the electromagnet. It may be a material.

  In addition, in the explanation so far, the powder discharge container or the powder storage container used for the powder dispenser has an additional shielding part in addition to the discharge port and the shielding part that shields the discharge port. The angle between the shielding part and the bottom surface is small, but even when using a powder container that does not have these characteristics, from the characteristics such as having a shielding part opening and closing part on the powder release device side, A certain degree of effect can be obtained to solve the problems of the present invention.
