Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter device for opening and closing a solid agent discharge port which opens and closes a passage for a solid agent transferred from a hopper into which solid agents (tablets, capsules, etc.) are introduced to the next step. .

[0002]

2. Description of the Related Art Conventionally, a hopper having a discharge port communicating with the discharge passage is connected to the upper surface of a body having a discharge passage formed in the upper portion, and the discharge port is opened and closed to form a solid agent from the hopper. There has been proposed a shutter device for opening and closing the solid agent discharge port, which is provided with a shutter for discharging and blocking the liquid at the outlet.

[0003]

However, in the above-mentioned conventional apparatus, the solid agent discharged from the hopper is conveyed to the steps such as dirt detection and packaging, but when there is a trouble in these steps, etc. It is necessary to stop the line, but in this case if the shutter is closed as it is, the solid agent may be caught between the side wall of the body and the solid agent may be damaged. The shutter was closed after all the solid agent fell and became empty. However, in this conventional case, when the work is restarted, a new solid agent is put into the empty hopper, which is the same as the operation from the start of work in the morning, so that the efficiency of the solid agent transfer operation is improved. There was a problem of decline. An object of the present invention is to provide a shutter device for opening and closing a solid agent discharge port, which does not cause a problem such as the solid agent being caught even if the shutter is closed while the solid agent remains in the hopper.

[0004]

Therefore, according to the present invention, a hopper having a discharge port communicating with the discharge passage is connected to the upper surface of a body having the discharge passage formed in the upper portion, and the discharge port of the hopper is connected. In a shutter device for opening and closing a solid agent discharge port having a shutter for opening and closing, the discharge passage is provided on an upper side of the body, and a bottom surface inclined downward from a lower side surface of the discharge passage is provided. An outlet is formed in the lower portion of the side wall of the body at the end of the end of the body, and the ceiling of the body is formed in a horizontal shape so that a large space is formed in the body above the outlet portion. A shutter is provided which is horizontally inserted into the body from the outer side of the upper position of the inclined bottom surface and has a tip that passes through the space and divides the inside of the body into two parts. The sub shutter for opening and closing between the road,
The sub-shutter is inserted from the outside in the direction opposite to the shutter, and has an opening of a size that allows the solid agent to drop from the hopper discharge port into the discharge passage even when completely closed. This is a means for solving the problem.

Further, according to the present invention, a hopper having a discharge port communicating with the discharge passage at a lower part thereof is connected to an upper surface of a body having a discharge passage formed at an upper part thereof, and a solid shutter having a shutter for opening and closing the discharge port of the hopper is provided. In the shutter device for opening and closing the agent discharge port, the body forms a space portion, which is obliquely upward and has a bottom surface inclined downward in the passage direction, at a side of the discharge passage, and a lower portion of the discharge passage. Is provided so as to communicate with the outlet, and is provided with a shutter that is inserted obliquely upward toward the space from the outside of the side surface of the lower portion of the discharge passage opposite to the space and divides the inside of the body into two. A sub-shutter that opens and closes between the hopper discharge port and the discharge passage is provided, and the sub-shutter is horizontally inserted from the outside on the opposite side to the shutter, and even when the hopper is completely closed, Those solid dosage from the outlet is as openings sized to fall into the discharge passage is formed, it is an unit for which a problem solution.

[0006]

When the main shutter and the sub-shutter are completely open, the solid agent put into the hopper drops from the discharge port at the bottom of the hopper into the discharge passage of the body and then flows down along the inclination of the bottom surface of the body, It is sent to the next process from the outlet at the bottom of the side wall. In this case, since the ceiling above the outlet is horizontal, a space is formed between the solid agent flowing down the inclined surface and the ceiling. At this time, if a situation occurs in which the operation of the next process is stopped, it is necessary to prevent the solid agent that has flown out so far from falling from the hopper. In this case, the sub-shutter is first closed, but even if the sub-shutter is completely closed, an opening through which the solid agent can drop is formed. Therefore, even if the sub-shutter is closed, the solid agent is caught at the tip thereof. Nonetheless, the solid agent continues to fall from this opening into the discharge passage from the hopper. At this time, even if the main shutter is closed from the side opposite to the sub-shutter, there is no solid agent in the space above the outlet portion of the body, so that it does not get caught. And the solid agent that gradually drops from the opening accumulates on the main shutter,
Eventually, the solid agent on the main shutter stops moving, so that the dropping of the solid agent from the hopper is finished and the solid agent is accumulated in the hopper. At this time, all the solid agent in the lower chamber below the main shutter is discharged from the outlet. The above is the case where the sub shutter is closed first, but even if the main shutter is closed while the sub shutter is open, the bottom surface of the body is inclined and the body outlet is formed at the tip. Therefore, the solid agent does not enter the space above the outlet of the body. Further, the solid agent slightly moves into the space as the main shutter moves, but the space is not filled with the solid agent enough to be caught between the tip of the main shutter and the side wall of the body. .

On the other hand, in the case of the present invention in which the main shutter moves diagonally upward, in the inclined space formed upward on the side of the discharge passage, the solid agent is filled from the discharge passage to the outlet. Even if it is full, the solid agent does not enter, so that the problem that the main shutter bites the solid agent does not occur. Further, in this case, if the sub-shutter is provided above, there is no possibility that the solid agent will enter the space, and even if the main shutter is closed, an accident such as biting the solid agent at the tip is absolutely impossible. Does not occur in Therefore, it is not necessary to drop all the solid material in the hopper before closing the shutter. And when the shutter is closed,
Since the solid agent remains on the closed main shutter and in the hopper, the solid agent remaining in the hopper and the solid agent accumulated on the shutter drop first when the next work is restarted, Since the solid agent newly introduced into the hopper continuously flows down following this, the transfer of the solid agent is not interrupted or interrupted, and the transfer efficiency of the solid agent is extremely good.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments of the drawings. FIGS. 1 to 3 show a first embodiment of the present invention. In the figure, 1 is an upper body, and 2 is a lower body, which together form the body of the first embodiment of the present invention. Reference numeral 3 denotes a main shutter, which is horizontally inserted into the body from a lateral outside at a boundary portion between the upper body 1 and the lower body 2 and has a discharge passage 6 provided above the side portion of the upper body 1. It is possible to block the communication with the outlet 8 formed in the lower body side wall 7 on the side opposite to 6. Further, on the upper surface of the upper body 1, the discharge passage 6
Is connected to a hopper 5 having a discharge port 9 that communicates with the lower part of the discharge passage 6 of the lower body 2,
The bottom surface 10 is formed to be inclined downward, and the discharge port 8 is formed below the body side wall 7 at the end of the inclined bottom surface 10. Further, the ceiling 11 is formed horizontally, and a large space 1 is provided in the body above the exit 8.
2 are formed, and in this space 12,
Even when the main shutter 3 and the sub-shutter 4 are both open as shown in FIG. 2 and the solid agent a is continuously flowing down from the hopper 5, in addition to the bottom surface 10 being inclined, There is no outlet 8 and the solid agent a continuously flows out, so that the space 12 is not filled with the solid agent a.

Therefore, the main shutter 3 is provided with the first and second shutters from the outside.
When inserted between the bodies of the
Even if the main shutter 3 is moved to the side, the space 12 is not filled with the solid agent a. No problems with solid agent entrapment between them occur. When the main shutter 3 is closed, an upper chamber 13 is formed between the main shutter 3 and the ceiling 11, and a lower chamber 14 is formed between the main shutter 3 and the inclined bottom surface 10. The reference numeral 7a is a groove formed on the inner surface of the side wall 7 with which the tip of the main shutter 3 is engaged and fixed. Reference numeral 4 denotes a sub-shutter that is arranged above the main shutter 3 and opens and closes a passage between the discharge port 9 of the hopper 5 and the discharge passage 6, and is inserted into the body from the outside on the side opposite to the main shutter 3. Even in the completely closed state, the opening 15 is formed in a size that allows the solid agent a to drop from the discharge port 9 of the hopper 5 into the discharge passage 8. FIG. 3 shows a state in which the main shutter 3 is closing after the sub-shutter 4 is fully closed from the discharging state.

Next, the operation of the first embodiment shown in FIGS. 1 to 3 will be described. When the main shutter 3 and the sub-shutter 4 are completely open, the solid agent a put in the hopper 5 will be described. After being dropped from the discharge port 9 in the lower part of the hopper into the discharge passage 6 of the body, it flows down along the inclination of the bottom surface 10 of the body and is sent to the next process from the outlet 8 in the lower part of the body side wall 7. In this case, since the ceiling 11 above the outlet is horizontal, a space 12 is formed between the solid agent a flowing down the inclined surface and the ceiling 11. At this time, when a situation occurs in which the next process is stopped, it is necessary to prevent the solid agent a that has flown out until now from dropping from the hopper 5. In this case, the sub-shutter 4 is closed first, but even if the sub-shutter 4 is completely closed, the opening 15 through which the solid agent can drop is formed.
The solid agent a does not bite at its tip, and the solid agent a continues to drop from the opening 15 into the discharge passage 6 from the hopper 5. At this time, even if the main shutter 3 is closed from the side opposite to the sub-shutter 4, it does not get caught because there is no solid agent in the space 12 above the outlet of the body. Then, the solid agent a that gradually drops from the opening 15 is accumulated on the main shutter 3, but eventually the solid agent a on the main shutter 3 stops moving, and the dropping of the solid agent a from the hopper 5 ends, and the inside of the hopper 5 is stopped. In this state, the solid agent a is accumulated. At this time, all the solid agent a in the lower chamber 14 below the main shutter 3 is discharged from the outlet. The above is the case where the sub-shutter 4 is closed first, but even if the main shutter 3 is closed while the sub-shutter 4 is open, the bottom surface 10 is inclined and the exit of the body is beyond that, Space 1 above the exit 8 of the body
The solid agent a does not penetrate into 2. Although the solid agent a moves a little into the space 12 as the main shutter 3 moves, the solid agent a is moved into the space 12 so that the solid agent a is caught between the tip of the main shutter 3 and the side wall of the body. Will not be filled with.

Next, FIG. 4 shows a second embodiment of the present invention, in which the body consisting of the upper body 1 and the lower body 2 is directed to the side of the discharge passage 6 and obliquely upward, and the bottom surface 16 is in the direction of the passage 6. A space portion 17 is formed so as to be inclined downward toward the bottom of the discharge passage 6. The lower portion of the discharge passage 6 communicates with the outlet 18.
Further, a shutter 3'that is inserted obliquely upward toward the space 17 is provided from the outside of the side surface of the lower portion of the discharge passage 6 opposite to the space 17, and the front end of the shutter 3'is the space 1.
7 and is locked in the groove 7a on the side wall of the body, the upper chamber 1 including the space portion 17a and the discharge passage 6 is inserted.
9, a lower chamber 20 including a space portion 17b and an outlet 18
Is divided into and FIG. 5 shows a third embodiment of the present invention. In the second embodiment of FIG. 4, a sub shutter 4 similar to that of FIG. 1 is provided to open and close between the hopper discharge port 9 and the discharge passage 6 of the body. However, even if the opening 15 is completely closed, the opening 15 shown in FIG.
It is formed in the same manner as in the above embodiment.

Next, the operation of the second and third embodiments shown in FIGS. 4 and 5 will be described. In this embodiment, the inclined space 17 formed at the side of the discharge passage 6 has an outlet from the discharge passage 6. Even if the solid agent a is filled up to the part, the solid agent a does not enter the space 17, so that the main shutter 3'will bite the solid agent a even if the main shutter 3'is closed. Nothing happens at all. In this case, according to FIG. 5 of the third embodiment in which the sub shutter 4 is provided above, the opening 1
Since the fall of the solid agent from 5 is reduced, the solid agent does not enter the space 17 at all. Therefore, the insertion of the main shutter 3'can be performed without any problem.

[0013]

As described in detail above, according to the present invention, there is a space in the body above the outlet, the bottom surface is inclined toward the outlet, and the sub-shutter is completely closed. Since the opening is formed at the tip, even if the main shutter and the sub-shutter are closed while the solid agent is flowing down from the hopper, the problem that the solid agent is caught does not occur at all. Therefore, unlike the conventional case, it is not necessary to drop the solid agent in the hopper before closing the shutter, and the solid agent remains on the closed main shutter and in the hopper. Therefore, when the next work is resumed, the solid agent remaining in the hopper and the solid agent on the shutter first drop, and subsequently the solid agent newly introduced into the hopper continuously flows down. Therefore, unlike the case where the conventional machine is stopped, the transportation of the solid agent is not interrupted or interrupted, so that the efficiency of transferring the solid agent is extremely good.
