Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a rotary type packing machine, and more specifically, it is divided into a necessary amount from a groove on a rotary table in which powder particles such as powdered medicines are distributed and supplied to a packaging section. The present invention relates to a rotary packaging machine having a cleaning mechanism that can be wrapped and that facilitates a cleaning operation after cutting out the powder or granules.

[0002]

2. Description of the Related Art Conventionally, powder particles such as powdered medicines are distributed and supplied to a concave groove provided on a rotary table, and the powder particles are cut out from the concave groove of the rotary table by a required amount and packaged. In a rotary type powder-packaging machine, as a cleaning mechanism, after cutting out the powder granules from the groove on the rotary table, before the next powder granule is received in the groove, the rotary brush makes a concave A method is adopted in which the powder particles remaining on the surface of the groove are swept away and the dust swept from the intake port connected to the suction pump is discharged to the outside of the machine. In addition, when dividing the granular material, the granular material is stopped in the groove,
The rotary plate and the scraping plate, which are used to cut and divide the powder particles by the scraping plate, are also cleaned by the brush after the splitting operation, and the dust is discharged to the outside of the machine by the suction pump. . The cleaning mechanism is provided outside the rotary table.

[0003]

As described above, the means for cleaning the residual adhered powder and granules of the main part of the rotary type powder and granule packing machine is provided outside the rotary table.
As a result, the cleaning device occupies the upper surface of the machine body, and there is a drawback that the machine body becomes large in structure. Further, since the rotary plate and the scraping plate for dividing and cutting out the powder and granules are integrated, it is not easy to reliably remove the fine powder particles adhering particularly to the peripheral edge of the rotary plate.

The fact that the powder particles of the previous process remain attached to the periphery of the rotary plate even after cleaning means that when the powder particles to be subjected to the next division cutting process are of different types, the powder particles of different types are present. This is especially a problem when the body is mixed and the treated product is a medicine, for example. Therefore, if it is attempted to reliably remove the fine powder particles adhering to the rotating plate or the like, it will take a lot of time to move to the next work, such as excessive rotation to lengthen the cleaning time.

According to the present invention, such a problem is solved and the rotary plate for damming and the cutting plate can be separately rotated so that the divided cutting portion can be easily and reliably cleaned. An object of the present invention is to provide a rotary packing machine in which the divided cutout portion and the cleaning device for the concave groove of the rotary table are arranged at a required position from the center of rotation of the rotary table.

[0006]

It is preferred that the mechanism is supported.

[0008]

According to the rotary packing machine of the present invention having the above-mentioned structure, when the cutting operation of the granular material is lifted from the annular concave groove after the operation of dividing and dividing the granular material from the annular concave groove of the rotary table is completed, The cleaning brush of the cleaning mechanism interlocked with the operation comes into contact with the rotary plate and the scraping plate. Therefore, the rotating plate and the scraping plate are idled, and the inside of the dust suction cover is sucked by the intake pump, at which time the rotating plate and the scraping plate are separately rotated to selectively rotate the cutting mechanism. Either the plate or the scraping plate can be rotated and cleaned until the dust is removed.

In the figure, reference numeral 13 is a guide roller for rotatably supporting the rotary table 10, 14 is a support ring attached to the rotary table 10, and 14 'is a support guide ridge provided on the inner circumference of the support ring 14.

On the upper side of the powder and grain cutting mechanism 21,
A cleaning mechanism 50 is provided. As shown in FIGS. 3 and 4, the cleaning mechanism 50 includes a rotating plate 22 and a scraping plate 23.
Cleaning brushes 51 and 52, which are capable of cleaning the contact portions of the respective particles when they come into contact with each other, are held and housed in a dust cover 53 surrounding the peripheries of the rear and rear portions. The dust cover 53 has a link 55 directly connected to the mounting seat plate 54, whose base end 55 'is supported by a pin 55 "at a position slightly ahead of the position of the support shaft 16 of the support arm 25, and the dust cover 53 On the adjacent side part, the tip of the cam link 56 is connected to the pin 56 '. The cam link 56 has a base end which is provided at a position opposite to the powder grain cutting mechanism 21 and which is an annular groove 11 for cleaning. The vertical operation support piece 58 that supports the cleaning brush 59 is connected to the center of the machine by a pin 56 "from a pivot shaft 58 '. The up / down operation support piece 58 of the rotary cleaning brush 59 is designed such that an attached cam follower 57 is constantly in contact with the cam 37 to be cleaned by the cam 37 in a predetermined order. In the figure, reference numeral 60 denotes a vertical operation drive mechanism for the powder particle cutting mechanism 21, the cleaning mechanism 50, and the rotary cleaning brush 59, and the cam 37
The driving force is transmitted to the rotary drive shaft 61.

Like the cover 58 "of the rotary cleaning brush 59, the dust cover 53 is connected to an intake pump (not shown) by a hose, and the dust suction operation is performed after the operation of dividing and cutting the powder particles is completed. It is done like this.

In use of the rotary type packing machine of the present invention thus constructed, when the support arm 25 of the powder grain cutting mechanism 21 is raised, the annular groove 11 on the rotary table 10 is used. The rotary plate 22 and the scraping plate 23 are lifted upward from the rotary table 10 (see FIG. 5 (a)), and the required amount of powder particles is fed from the feeder 41 of the powder / particle supply mechanism 40 onto the rotating table 10 which is rotating in that state. The body A is distributed and supplied to the annular groove 11. In this state, the cleaning mechanism 50 and the rotary cleaning brush 59 of the annular groove 11
Is in a retracted state.

When the supply of the granular material A to the annular concave groove 11 of the rotary table 10 is completed, the rotary table 10 is rotated at a speed corresponding to the number of divisions, and the support arm 25 of the cutting mechanism 21 is correspondingly rotated. It is lowered by the rotation of the cam 37, and as shown in FIG. 5 (b), the rotary plate 22 is inserted into the annular groove 11, and the scraping plate 23 is rotated at a predetermined speed. At the time of the first cutout of the granular material, the drive of the rotary plate 22 is stopped, and only the scraping plate 23 is rotated to rotate the rotary plate 22.
Thus, the granular material A held in the annular groove 11 is cut out and sent to the supply chute 45 for the packaging mechanism.

After that, the rotary plate 22 and the scraping plate 23 are simultaneously rotated to cut out the required number of packages. With this kind of operation,
The cutting amount of the powder and granules of the first package is only the scraping amount by the scraping plate 23, and the powder and granules adhere to the rotary plate 22 without being taken out. The powdery particles thus obtained are sent to the packaging unit via the supply chute 45 and packaged.

When the operation of dividing and supplying all the packages is completed, the rotation of the cam 37 raises the support arm 25 through the cam follower 37 ', and the powder particle cutting mechanism 21 is operated.
Are lifted and retracted. At the same time, the rotating cleaning brush 59
The cam follower 57 on the side of the vertical operation support piece 58 is in a state in which the pushing down action of the cam 37 is removed, and the cam link 56 whose base end is connected to the vertical operation support piece 58 is in a state of being lifted. As shown in Fig. 5 (c), the cleaning mechanism
The link 55 of the 50 is placed along the upper surface of the support arm 25, and as a result, the cleaning brushes 51 and 52 of the cleaning mechanism 50 are rotated.
If the powder and granules that come into contact with the scraping plate 23 and the scraping plate 23 are cleaned and removed, the dust is sucked by the suction pump connected to the dust suction cover 53 and is removed outside the machine. Simultaneously with this operation, the rotary cleaning brush 59 at the opposite position is brought into contact with the annular groove 11 to clean the surface of the annular groove 11.

Then, in the process of rotating the rotary plate 22 and the scraping plate 23 to remove the powdery particles, the rotation of the rotary plate 22 and the scraping plate 23 is changed according to the adhered state of the powdery particles. If, for example, it is not possible to easily remove the powder or granules of the rotary plate 22, only the rotary plate 22 is rotated for a long time to remove the adhered powder or granules, or only the scraping plate 23 is lengthened. It can be cleaned according to the situation, such as rotating to remove the adhering powder particles. Therefore,
During the next operation, the work can be performed without mixing the treated powder and granules.

After the cleaning operation is completed, the rotation displacement of the cam 37 causes the link 55 of the cleaning mechanism 50 and the vertical operation support piece 58.
And are lifted, the cleaning brushes 51, 52 and the rotary cleaning brush 59 are lifted, and are returned to the state shown in FIG. 5 (a), so that the granular material A can be supplied.

[0023]

According to the present invention, after the granular material is divided into the required number from the annular concave groove on the rotary table and sent out to the packaging mechanism, when the cutting mechanism of the granular material is cleaned, the rotational movement is performed. Since the plate and the scraping plate are driven and rotated separately, the rotary plate and the scraping plate can be used according to the degree of the adhesion in order to clean the powder particles attached during the cutting operation. The cleaning operation with the cleaning brush can be performed by setting the contact time arbitrarily according to the conditions, so even if the powder with high adhesion is divided, it can be processed without disturbing the next work. The cleaning mechanism can also be simplified and downsized.
