Description

The present invention relates to a powder packaging machine for packaging powder, and particularly to a powder discharging device for discharging powder to a powder packaging device which is a part of the powder packaging machine and a powder containing container used together with the powder discharging device. The present invention relates to a powder storage container and a powder discharge device that can prevent delivery and accurately measure and discharge powder into a powder packaging device.

Regarding the powder dispensing business, in the conventional device, the pharmacist weighs the amount of one prescription for a predetermined drug in advance on the weighing table, and then puts this into the device, so that the number of packages is reduced to the specified number of packages by the distribution device. It was divided and the divided powders were individually packaged one by one with a packaging machine. On the other hand, in recent years, in order to reduce the burden of pre-weighing work by pharmacists, devices and systems that can automatically perform weighing for one prescription have been put into practical use.

For example, Patent Document 1 is a drug dispensing device that takes out a predetermined amount of powder from a powder storage container, divides the powder into a predetermined number, and further individually packages and discharges the powder. A container for storing powder, having a discharge port for discharging the contained powder, a container storage device for storing a plurality of powder storage containers, and a container for moving the powder storage container. A moving device is provided, and 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, from the powder storage container mounted on the container mounting device. Discharge of 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 horizontally placed (the discharge port is). (Horizontal direction of the bottom surface), and in that state, it is placed on the container mounting device.

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 it is preferable to install it vertically because of the occupied area of the storage device. , When stored in the storage device, by moving the part that becomes the powder discharge port upward, the powder is moved to the lower part of the powder storage container (far away from the discharge port), so it is moved or mounted on the container. It is said that it is possible to prevent powdered medicine from spilling when it is placed on a placement device or immediately before it is discharged by opening the discharge port.

However, in each of these devices, a container containing a large number of drugs is arranged in advance on a shelf, and the container is moved to the measuring unit by using an articulated robot or a means such as an articulated chain movement. It was large and had to be expensive.

Generally, a small dispensing pharmacy cannot install a large device because its space is small, and it is necessary to prescribe tablets as well as powder for dispensing. However, if such a large device is installed in a small pharmacy, tablets There is also the problem that a packaging machine cannot be installed, 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 an articulated chain movement. A method for preventing powder spills without changing the posture of the powder storage container is required.

Here, the powder storage container must always be provided with a discharge port for discharging the drug. Normally, this discharge port is closed, moved or detached, and then attached to the powder discharge device. The door of this discharge port is opened, the drug is discharged and weighed, and after completion, the door of the discharge port is closed again, and then the attachment / detachment / movement is performed. At that time, there are two problems as described below.

FIG. 12 is an explanatory diagram of a conventional powdered medicine container. The powdered medicine container 1 contains the powdered medicine P inside. As shown in FIG. 12A, a shielding plate 3 rotatably supported by a shaft 2 is provided on the left side of the powder storage container 1 to close the discharge port 4 of the drug P.

FIG. 12B shows a state in which the shielding plate 3 of the discharge port 4 of the powder storage container 1 is opened by a means (not shown). When the shielding plate 3 is opened and driven by another vibrating means or the like, the drug P can fall from the discharge port 4 in the direction of the arrow 5. The first problem is that, just by opening the shielding plate 3 without applying vibration drive, the pile of the drug P at the tip of the discharge port 4 collapses a little and falls like P1. ..

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

The maximum angle of a slope that voluntarily maintains stability without collapsing when powdered fluids such as powder are piled up is called the "angle of repose". On the other hand, the "collapse angle" indicates the angle when the powder that is stationary at the angle of repose is collapsed by giving a constant impact.

Here, if the angle formed by the shield plate and the bottom surface of the powder storage container is larger than the angle of repose (or collapse angle), if the powder is collected in contact with the shield plate, it will be in a stationary state (or impact). If the shield is opened (while giving), powder may spill out.

Next, the second problem will be described. FIG. 12C shows a state in which the shielding plate 3 of the discharge port 4 of the powder storage container 1 is closed by a means (not shown). Although it is schematically drawn large here, there is a possibility that a part of the 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 created.

There are various shapes of powders, but when a large particle size such as granules is sandwiched, the gap is large. In this state, if the discharge port 4 is turned slightly downward, the drug will spill further.

Even if the amount of unnecessary powder spilled due to these two problems is small, it is difficult to control where the spilled powder falls and adheres, resulting in unintended other drugs. It may lead to contamination with.

Japanese Patent No. 5953471

Hospital Pharmacy Vol. 19, No. 2 (1993)

In view of the above problems, the problem to be solved is to prevent powder from spilling from the powder storage container when providing a small, space-saving, low-priced powder packaging machine with an automatic weighing function. It's a difficult point.

In order to solve the above problems, the first invention is a powder storage container that can be accommodated for discharging powder and can be attached to a powder discharge device, and has a discharge port for discharging powder. It has a shielding portion that shields the discharge port and an additional shielding portion that further shields the discharge port, and is placed horizontally, and the additional shielding portion is mechanically attached to and detached from the powder discharge device. It is characterized by being opened and closed.

The powder storage container is a substantially rectangular parallelepiped, box-shaped having a bottom surface, and when the container is placed with the longitudinal direction as the substantially horizontal direction, this posture is referred to as “horizontal placement”.

In this way, since the shielding portion that shields the discharge port is provided twice, it is possible to prevent the powder from spilling even if the powder storage container is moved without changing its posture while being placed horizontally. ..

Further, even if the powder is caught in the shielding portion, the additional shielding portion can prevent the powder from spilling out of the powder storage container.

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

Alternatively, in order to solve the above-mentioned problems, the second invention is a powder containing container that can be contained for discharging powder and can be attached to a powder releasing device, and discharges powder. The shielding portion has an outlet and a shielding portion that shields the discharge port, and is placed horizontally, and the shielding portion opens at an angle formed with the bottom surface of the shielding surface of the shielding portion in the vicinity of the shielding portion. It is characterized in that the shielding portion is movable along the end face of the discharge port at an angle or less at which the powder does not collapse in a stationary state.

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

Further, the fact that the shielding portion can operate along the end face of the discharge port indicates the following state.

First, the end face of the drain port is provided so as to have an angle (for example, about 30 degrees) that is equal to or less than the angle of repose of the powder when the bottom surface of the powder storage container near the drain port is horizontally installed. ..

Therefore, for example, a linear motion bearing fixed to the shielding portion slides on an axis parallel to the shielding surface of the shielding portion by a drive mechanism.

By doing so, the shielding portion can operate along the end face of the discharge port, so that the discharge port can be opened and closed.

By enabling such an operation, even if the drug adheres to and remains on the end face of the discharge port due to static electricity or the like, the drug is pushed out by the closing operation of the shielding portion, and the shielding portion and the discharging port are closed at the time of closing. There is no gap between them.

Further, in the present invention, the powder storage container mounting portion to which the powder storage container described above is attached, the shielding portion opening / closing portion for opening / closing the shielding portion of the powder storage container, the powder storage container and the storage are contained. It may be an embodiment of a powder discharge device having a measuring unit for measuring the weight of the powder and a powder discharge unit for discharging the powder from the discharge port of the powder storage container.

In this way, the powder storage container is attached to the powder storage container attachment portion of the powder discharge device, and the shield portion is opened by the shield opening / closing portion provided on the powder discharge device side, and the powder is released by means such as vibration. A powder storage container is attached so that the powder in the powder storage container is released by the unit 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 attachment part. Subsequent series of automation can be realized.

That is, even when the powder storage container is manually transported and attached to the powder discharge device while it is placed horizontally, the shield opening / closing part is built in the powder discharge device, so that the powder spills out. It is possible to realize simple automation while preventing the above.

In the case of using an automatic transportation means such as an articulated robot as in the past and having a means for opening and closing the shielding portion on the automatic transportation means side, the shielding portion opens at the timing of installing the powder storage container in the powder discharge device. At that time, spillage may occur due to an external force such as vibration. However, according to the present invention, since the shield opening / closing portion is provided on the powder discharge device side, the powder storage container is powdered. After installing in the discharge device, the shield can be opened without any external force, and the risk of spillage can be reduced.

Further, the present invention is in the embodiment of a powder packaging machine having a powder containing container and a powder discharging device described above, and a powder packaging device for distributing and packaging the powder released from the powder discharging device. There may be.

In this way, it is possible to consistently automate even the packaging of powdered medicine.

According to the powder container, the powder discharge device, and the powder packaging machine of the present invention, it is possible to provide a small and space-saving powder packaging machine with an automatic weighing function, in particular, during storage, transportation, and. , It is possible to prevent powder from spilling from the powder storage container when it is set in the powder discharge device.

It is a front view of the powdered medicine packing machine 100 which concerns on a form.

The powder packaging machine 100 distributes and packages a powder storage container 200 that stores the powder to be packaged, a powder discharge device 300 that attaches the powder storage container 200 and discharges the powder in the powder storage container 200, and the released powder. It is composed of a powder packaging device 400 to be used.

However, the separation of these devices is not limited to this, and any separation may be used as long as it can exhibit the same function.

Each component will be described below.

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

The powder storage container 200 is a substantially rectangular parallelepiped, box-shaped having a bottom surface, and is placed with the longitudinal direction as the substantially horizontal direction. This posture is placed horizontally.

The powder storage container 200 rotatably holds an upper lid 201 on the upper portion, a powder discharge port 202 on the lower side surface, a shielding portion (shielding plate) 203 for shielding the discharge port 202, and a shielding portion 203 at the outlet portion of the discharge port 202. The shielding portion rotating shaft 204, the additional shielding portion 205 provided on the outer portion of the container from the shielding portion 203, the additional shielding portion rotating shaft 106 for rotatably holding the additional shielding portion 205, the shielding portion 203, and the addition. A leaf spring 207 that urges the shielding portion 205 in the closing direction, a push plate 208 that is provided at the lower end of the shielding portion 203 and allows the shielding portion 203 to rotate in the opening direction when pushed, and an iron plate that is a magnetic material on the outside of the bottom surface. Has 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 portion 203 and the additional shielding portion 205 with a common leaf spring 207 has a great effect of reducing the number of parts, but a separate urging means may be provided for each shielding portion. Depending on the mass of the shield and the opening / closing timing, it may be more advantageous to separate them.

As shown in the figure, the bottom surface of the powder storage container 200 when placed on a horizontal surface is horizontal at the center, and the front (outlet side) and the rear (opposite the discharge port) are slightly inclined upward. It has a pan-bottomed shape. This should not be too close to the outlet 202 to prevent leakage of the contained powder and should not be too close to the rear to facilitate the discharge of the contained powder at the time of discharge. It was intended.

However, the bottom surface may be a horizontal or non-horizontal uniform flat surface. Depending on the nature of the powder, the handling method of the powder storage container, etc., it may be advantageous to have a uniform flat surface that can be easily processed. Further, even when only one of the front and the rear is slightly inclined upward, the above-mentioned effect can be obtained to some extent.

Further, the angle A formed by the bottom surface of the powder containing container 200 near the discharge port 202 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 discharge device, the bottom surface near the discharge port 202 is placed horizontally, so that it is a horizontal surface of the shielding surface of the shielding portion 203. The angle formed is set to be equal to or less than the angle (called the 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 angle of repose according to the present invention. Here, for example, regarding the angle of repose, 43.5-54.5 degrees for powder-based powders and 31.0- for fine granules. The temperature is 34.5 degrees, and that of granules is 36.0-36.5 degrees.

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

However, depending on the powder used, a larger angle (35 degrees, 40 degrees, etc.) may be sufficient, or a smaller angle (25 degrees) may be taken into consideration for the collapse angle (13.0-32.0 degrees). , 20 degrees, 15 degrees, etc.) may also be effective.

In this embodiment, the shielding portion 203 has a plate-like shape having a rotation center above the discharge port 202, and may be referred to as a shielding plate. However, the shape is not limited to the plate shape, and it may be rod-shaped, columnar, or other shape, and at least the portion that shields the discharge port 202 may be flat. Further, the opening / closing method is not limited to the one having the plate-shaped end as the center of rotation, 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 the powder discharge device 300 according to the embodiment of the present invention, and FIG. 7 is a perspective view showing the relationship between the powder discharge device 300 and the powder storage container 200 according to the 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. It has an opening / closing unit 312.

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 fixture 304 is provided on the fixing plate 303 with a leg portion and a flat plate portion supported by the leg portion, on which an element of the device is fixed.

The measuring unit 305 is installed on the flat plate of the fixture 304, and the vibration base 306 is placed on the upper surface thereof. Therefore, the total mass mounted on the vibration base 306 is loaded on the measuring unit 305, so that the mass is massed. It is possible to measure.

The measuring unit 305 is preferably a platform scale, but is not limited to this, as long as it can measure the weight of an object placed on the load cell or the like.

The vibration base 306 has a leg portion that is inclined so that the powder outlet direction (forward) is low, 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 the 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, while the magnetic iron material 310 is arranged on the powder storage container mounting portion 308 while holding a slight gap relative to each other. As a result, when an AC electric waveform is input to the first electromagnet 309, the iron material 310 exhibits a vibrational behavior of being attracted to or separated from the first electromagnet 309.

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

The iron material 310 of the vibration base 306, the first electromagnet 309, the leaf spring 307, and the powder storage container mounting portion 308 are collectively referred to as the powder discharge unit 320.

However, the configuration of the powder discharge unit 320 is not limited to that by an electromagnet, and vibration may be generated by a piezoelectric element as long as the powder can be discharged little by little, or the spiral screw drive is not limited to vibration. Or something else.

The second electromagnet 311 is provided with the magnetized surface exposed on the upper surface of the powder storage container mounting portion 308. This can adsorb the iron plate 209 attached to the bottom surface of the powder containing container 200 by energization, and fix and hold the powder containing container 200 to the powder containing container mounting portion 308.

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

The shield opening / closing portion 312 is not limited to a mechanism consisting of a direct acting electromagnetic solenoid and a push plate 208 on the shield side. For example, a lead screw is directly connected to the motor and the rotation of the motor is regarded as a linear motion of the push plate. Various things such as pushing 208, using a push plate, or without using a push plate, operating various drive sources provided on the powder discharge device 300 side, and rotating the shielding portion 203 by a link mechanism, etc. A known actuation mechanism may be used.

<Powder packaging 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 device 400 according to the embodiment of the present invention.

The powder packaging device 400 includes a disk distribution unit 401 that receives and distributes 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. -It has a powder packaging unit 404 for arranging a packaging paper at the outlet of the chute 403 and enclosing and packaging the powder in the packaging paper.

The disk distribution unit 401 is composed of two sets of left and right disk distribution units 401A and a right disk distribution unit 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. Further, as the powder packaging machine 100 as a whole, a plurality of sets of such disk distribution units 401 may be arranged.

It should be noted that the number of these arrangements is an example, and may be less or more than this. It may be appropriately selected according to the purpose of use.

The cut out powder drops downward through the hopper chute 403, and a powder packaging unit 404 capable of enclosing the powder in the packing paper arranged corresponding to the outlet of the hopper chute 403 is arranged. There is.

Next, the operation according to the 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 the embodiment of the present invention is attached to or removed from the powder discharge device 300. Further, FIG. 10 is a cross-sectional view showing an operation in the vicinity of the discharge port 202 of the powder storage container 200 in the attachment / detachment operation of the powder storage container 200 according to the embodiment of the present invention.

The individual powder P is filled in the powder storage container 200 by opening the upper lid 201 at another place, closing the upper lid 201 again, and then carrying it by hand. At this time, since the shielding portion 203 is in the “closed” state and the additional shielding portion 205 is in the “closed” state as shown in FIGS. 9 (a) and 10 (a), the discharge port 202 is in a double closed state. The powder does not spill even if it is operated roughly by hand.

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

As shown in FIG. 10A, the angle A formed by the bottom surface near the discharge port 202, which becomes horizontal when attached to the powder discharge device 300, and the shielding surface of the shielding portion 203 is equal to or less than the angle of repose. Therefore, even if the shielding portion 203 is opened after being attached to the powder discharging device 300, there is little possibility that the powder will spill out.

At this time, the protrusions 210 provided on the left and right sides of the additional shielding portion 205 are pressed against the slope portion 314 of the container mounting guide body 313, so that the additional shielding portion 205 is opened. At this time, the shield portion 203 is “closed” and the additional shield portion 205 is “open” in FIG. 10 (b).

Next, when the device is notified of the "set completion" of the powder storage container 200 by an input device (not shown), the second electromagnet 311 of the powder discharge device 300 is driven by the control unit (not shown) 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 becomes the standby state of the powder discharge device 300. In this state, the powder storage container 200 is in a state in which the front surface (discharge port side) is slightly lowered and inclined, and the bottom surface in the vicinity of the shielding portion 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 an angle of repose, and when the shielding portion 203 is gently opened, the powder does not spill by itself.

Next, when instructed to release the drug P from the powder storage container 200 by a predetermined mass, the shield opening / closing unit 312 is first driven, whereby the shield 203 of the powder storage container 200 is opened. At this time, the shield portion 203 “open” and the additional shield portion 205 “open” in FIGS. 9 (c) and 10 (c) are obtained.

After that, the disk 402 of the disk distribution unit 401 of the powder packaging device 400 whose surface is arranged at the bottom of the powder discharge port 202 is rotated at a constant speed, and subsequently, the first electromagnet 314 is driven to drive the third electromagnet 314. When the base 313 is vibrated, the powder storage container 200 coupled to the base 313 also vibrates, so that the powder is deposited in a donut shape on the rotating disk 402 from the powder discharge port 202.

At this time, the total mass on the first base is continuously weighed by the measuring unit 305, and when the predetermined mass (for example, the amount specified by the prescription) is reached, 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 drive of the shield opening / closing portion 312 is released, the shield portion 203 of the discharge port 202 is closed.

As a result, even if a disturbance such as vibration is applied from the outside, the powder P in the vicinity of the discharge port 202 does not spill out.

Next, the donut-shaped pile of powdered medicine formed 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, divided into 10 equal parts) instructed by the control unit is performed. It is distributed in 1 package by cutting out at a cutting part (not shown).

The cut out powder drops downward through the hopper chute 403, and the drug P is enclosed in the packing paper of the powder packaging section 404 provided at the outlet of the hopper chute 403. In this way, for example, a packaged state of 10 packages per prescription is completed.

When removing the powder storage container 200 after the series of treatments is completed, the operation opposite to that at the time of attachment is performed. Then, the shielding portion 203 and the additional shielding portion 205 are leaf springs 207 which are common urging means in the closing direction (shown in FIGS. 4 and 9 (c), not shown in FIG. 9 (a)). , The outlet 202 is doubly shielded (closed) and can be moved to another place without worrying about spilling.

FIG. 11 is an explanatory diagram of a shielding portion 503 of a powder containing container according to another embodiment of the present invention. The discharge port 502 of the powder storage container is provided with a shielding portion 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 angle of repose of the powder when the bottom surface of the powder storage container near the discharge port 502 is horizontally installed.

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

By a drive means (not shown), the shielding portion 503 can be operated along the end face of the discharge port 502, so that the discharge port 502 can be opened and closed. FIG. 11A is a “closed” state, and FIG. 11B is an “open” state.

By enabling such an operation, as shown in FIG. 11C, even when the drug P2 adheres to and remains on the end face of the discharge port 502 due to static electricity or the like, the drug is closed by the closing operation of the shielding portion 503. When P2 is pushed out and closed, no gap is created between the shielding portion 503 and the discharge port 502 by sandwiching the drug.

In the above description, it has been described as preventing the powder from spilling when the powder storage container is handled manually, but even if the robot or the like automatically performs the powder storage container without human intervention. The present invention is effective and has an advantage that the precision of control of a robot or the like can be reduced.

Further, in the above description, the portion attracted by the electromagnet is described as an iron plate or an iron material which is a magnetic material, but the substance is not limited to iron as long as it can be attracted by the electromagnet. It may be a material.

In the above description, the powder discharge device or the powder storage container used for the powder packaging machine has an additional shielding portion in addition to the discharging port and the shielding portion that shields the discharging port, or / and.
