Description

[0001] Powder type disposable packaging module device [0002]

The present invention relates to a powder supply device for monitoring misdetection of dropping failures that do not drop a predetermined amount from a weighing mass when supplying various powders using a weighing mass, a powder filling device for filling and sealing the powder in a packing bag, And a method of manufacturing the package.

Various kinds of medicines and medicines, seasonings such as granulated sugar, deoxidants and other powders whose main ingredient is iron or an easily oxidizing compound, and products in which a certain amount of this powder is packed in small pockets made of paper or plastic Is widely known as a form. Generally, a powder filling packing machine is used for automation at the time of packaging. The powder filling packing machine measures a certain amount of powder and then guides the powder into the packing bag through a chute or the like. In addition, weighing of powder has been widely used in volumetric methods for charging powder into a space (metering mass) having a certain volume.

When the powder filling and packaging machine is operated, a certain amount of the metering mass is not charged due to a failure of the shutter mechanism in the lower opening of the metering mass, charging failure due to foreign objects in the charging section, etc., There is a problem that the amount of powder in the weighing mass is lower than a certain amount immediately before (charging failure) occurs. In addition, powder may fall off later than the position at which the powder should fall from the weighing mass due to clogging of the powder in the weighing mass, poor flowability of the powder, defective operation of the lower opening shutter mechanism of the weighing mass, or the like, (Failure to drop) may occur in some cases.

In a packaging bag in which such a problem occurs, a certain amount of powder is not charged and becomes a defective product. As a method for detecting such defective products, a weight inspection for measuring the weight of each powder package body by one is generally known. However, this method can not cope with high-speed automatic recharging packaging. In addition, this method can not be applied to a continuous bag shape in which one powder package is not separated and is continuous in a strip shape. Therefore, there has been a general method of measuring the weight by continuously sampling the powdery body continuously produced at a predetermined time or a predetermined number of times.

The failure due to the clogging of the powder in the measuring mass and the clogging of the foreign object often occurs when the failure occurs once, and in such a case, the above sampling method is effective.

However, if a bad state occurs suddenly, it can not be found by the above sampling method. Therefore, a phototube (tube) is installed at a certain position through which the powder package of the powder filling and packaging machine is passed, and the height of the powder is detected with respect to the whole of the powder package filled with the amount of transmitted light, A method of inserting a sieve and detecting that the thickness is equal to or more than a predetermined value is known.

However, these methods have a large error due to the non-uniformity of the individual powder package and the difference in the filling shape of the powder due to vibration, and if the sensitivity is raised, the malfunction increases. Further, in the case of a powder package which is filled with two kinds of powders having different volume ratios as in some deoxygenating agents, there is a drawback that the shortage of powder having a small volume ratio can not be detected substantially. Therefore, it is extremely difficult to know whether or not the right powder is filled in the mode powder package.

Thus, it is determined whether or not the powder to be supplied to the packaging bag remains in the weighing mass without directly checking the presence or absence of the powder packed in the packaging bag, thereby determining whether or not the powder is securely filled in the packaging bag Have been proposed. Specifically, a depth measuring sensor for measuring the depth of the weighing mass is used to measure the weight of the weighing mass at the stage of closing the shutter of the lower opening of the weighing mass by opening the shutter of the lower opening of the weighing mass, Place it on top of the raw material weighing dish to correspond. Then, the depth of the weighing mass is measured by the depth measuring sensor at the step of closing the shutter of the lower opening of the weighing mass, and the presence or absence of the powder in the weighing mass is checked by comparing this weighing with the depth of the empty weighing mass (Patent Document 1).

Patent Document 1: Japanese Patent No. 3662276

In the supply confirmation of the powder described in Patent Document 1, the powder feeder must recognize that the weighing mass has moved to the irradiation position of the laser beam, and irradiate the laser beam at this timing. Further, the depth of the weighing mass must be calculated based on the reflected laser light. It should also be compared with a normal measured depth. As described above, since a very large load is applied to the control of the apparatus, it takes time to detect an abnormality, which hinders the speed-up of the apparatus. Whether laser light is irradiated to the weighing mass or laser light is irradiated to the upper surface of the rotating plate when the movement timing of the plate on which the weighing mass is provided or rotation failure or speed change of the rotation plate occurs Thereby making it easy to cause malfunction of the apparatus.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to enable high-speed operation because anomaly detection is simple. And an object of the present invention is to provide a powder feeder, a powder filling machine, and a method of manufacturing a powdered package.

As a result of careful examination of the problem of poor filling of the powder with respect to the weighing mass and failure of the powder to fall from the weighing mass, the inventors of the present invention have found that both the filling failure and the dropping failure pay attention to the position of the powder- , In particular, in the case of a drop failure in which only a part of the powder in the weighing mass falls, a part of the lower part of the weighing mass falls down, and the upper part remains in its original position. In addition, it is confirmed that the device is a practical device with extremely few malfunctions due to actual operation and high effect, and the present invention has been completed. Further, in the present specification, a hole serving as a weighing mass may be referred to as a weighing mass.

A powder supply device according to the present invention comprises a member having a plate portion with a through hole formed therein, a motion mechanism for moving the member so that the upper opening of the hole moves along a constant movement path, An opening and closing member for bringing the lower opening of the hole into a closed state and an opened state accompanied by the opening of the hole, a powder charging unit for charging a predetermined amount of the powder into the hole in a predetermined section of the moving path, And a sensor provided on the upper side of the path for continuously monitoring the movement path on the plate.

In addition, the powder filling packing machine of the present invention comprises a member having a plate-like portion with a hole formed therethrough, a movement mechanism for moving the member so that the upper opening of the hole moves on a constant movement path, An opening and closing member for bringing the lower opening of the hole into a closed state and an open state; a powder charging section for charging a predetermined amount of the powder into the hole in a predetermined section of the moving path; An encapsulating part for encapsulating the powdered bag packed with the powder guided from the guide part, and an encapsulating part for encapsulating the powdered encapsulated encapsulated encapsulating material, And a sensor for continuously monitoring the movement path.

The present invention also provides a method of manufacturing a powder package, comprising the steps of moving a member having a plate-like portion with a perforated hole so that the upper opening of the hole is moved along a constant path, and closing the lower opening of the hole with an opening / A powder charging section for drawing a predetermined amount of powder into the hole in a predetermined section of the movement path; and a powder charging section for guiding the powder dropped from the hole to the packaging bag when the lower opening of the hole is open An encapsulating unit for encapsulating the packed bag filled with the powder guided from the guide unit and a sensor provided on the path of the path other than the predetermined section of the path to continuously monitor the path of travel on the plate, And the like.

The present invention also provides a method of manufacturing a powder package, comprising the steps of moving a member having a plate-like portion with a perforated hole so that the upper opening of the hole is moved along a constant path, and closing the lower opening of the hole with an opening / A step of filling the hole with a predetermined amount of powder in a predetermined section of the moving path; a step of dropping the powder in the hole while the lower opening of the hole is in an open state; A step of guiding and charging the powder in a packaging bag located on the lower side of the upper part of the plate, and a step of sealing the packaging bag, wherein a sensor provided on the upper side of the path other than the predetermined section of the movement path, Continuously monitors the above-mentioned moving behavior of the upper part, and when an abnormality is detected, It is characterized in that for performing.

Since the powder feed device, the powder filling packing machine and the powder package manufacturing method having such a structure continuously monitor the movement path of the upper opening of the hole in the upper part of the plate, the upper surface of the powder in the hole and the columnar surface It is monitored continuously. Therefore, there is no need to control the sensor to operate the sensor at the timing when the hole moves to the right of the sensor or to recognize that the device is monitoring the hole. Because of this, the load to be given to the control of the apparatus is very small, so that the speed of the apparatus can be increased.

Further, for example, when the member having the plate-like portion is the original plate, it is possible to suppress the malfunction of the apparatus even when the movement timing of the original plate provided with the holes, the defective rotation or the speed change occurs.

In addition, it is possible to precisely exclude defective products that have been difficult to monitor in the past. Therefore, a high-quality powder package can be provided to the world.

The powder charging section may be configured to deposit a predetermined amount of powder on the main surface of the upper part of the plate. In such a case, the present invention monitors the state of the upper surface of the powder deposited on the main surface and the surface of the powder filled in the hole by monitoring the path of the upper opening of the hole on the upper surface of the plate.

Also, it is appropriate that the powder charged in the hole and the sedimented donut powder on the main surface of the plate are made to have the same height. With this configuration, if a change occurs in the sensor before falling from the powder hole after filling the powder, it is possible to make the charging failure to the hole. In addition, when the sensor does not change after the drop of the powder, it is possible to make the drop failure.

As described above, since the position of the hole is not specified and the monitoring is simple and the processing time delay and the calculation process that causes the control (sequencer) load can be minimized and the defect can be judged, And so on.

In addition, by providing a plurality of sensors, it is possible to carry out the management of the charging package with higher precision by using the drop failure monitoring and the charging failure monitoring together.

It is preferable that the sensor is provided on the upper side of the movement path in a state in which the opening / closing member is in a state in which the lower opening of the hole is opened after the sensor is charged with a certain amount of powder in the hole. It is preferable that the surveillance is performed until the opening member closes the lower opening of the hole after the hole is filled with a certain amount of powder. With such a configuration, charging of the powder can be monitored.

Further, in the present invention, it is preferable that the sensor is provided on the upper side of the movement path in the open environment of the lower opening of the hole. It is preferable that the monitoring is performed while the lower-side opening of the hole is in the open state, and the falling of the powder from the hole is monitored. With this configuration, according to the present invention, There is a large difference between the output of the monitoring of the upper surface of the powder in the hole by the sensor and the output of the surface monitoring of the upper surface of the plate. On the other hand, when the powder does not fall normally from the hole, there is no difference between the monitoring output of the upper surface of the powder in the hole by the sensor and the monitoring output of the main surface. Therefore, the drop failure of the powder can be monitored with high precision.

Further, in the present invention, it is preferable that the plate-shaped portion is a disk-shaped member, and the exercise mechanism is a rotating mechanism for moving the member so that the plate-shaped portion rotates. With this configuration, it is possible to arrange the holes on the circumference, and by repeating (circulating) the powder filling into the holes and the dropping of the powder from the holes as the circumferential angle progresses, Suitable.

According to the powder supply device, the powder filling packing machine and the method of manufacturing the powder package of the present invention, it is possible to speed up the operation and suppress the malfunction.

The powders referred to in the present invention generally include not only powdery materials having a particle size of 100 microns or less but also granular and granular materials having a particle size of several millimeters or less and are used in various medicines, And an oxygen scavenger as a main raw material.

The powder feeder and the powder filling and packaging machine of the present invention are characterized in that a plurality of holes passing through the plate-like portion of a member having a plate-shaped portion having a predetermined thickness and rotating or reciprocating along the main surface are placed on a circumferential or straight line And the opening / closing member is further provided at the lower opening of the hole. Further, the lower opening of the hole is closed, and the powder is filled in the hole at a position functioning as the measuring mass, and the powder is dropped from the hole by gravity while the lower opening of the hole is opened. The dropped powder is guided through a chute, which is an induction part for charging, into a small pocket of the lower part. A powder feeder or a powder filling packing machine having such a volume metering (metering mass) formula is suitable.

According to the powder supplying apparatus of the present invention, since the falling of the powder (3) filled in the hole (2) can be precisely monitored, the supply of the powder can be stabilized.
