Description

The present invention relates to a container and a container discharge device including an on-off valve operating device for operating the on-off valve device of the container.

Conventionally, in a wide range of industrial fields, containers (hoppers) suitable for storing and transferring powders, granular materials and the like (hereinafter referred to as "powder and granular materials") have been known. Suitable containers for such granules generally have a cylindrical or square cylinder shape at the top, a funnel-shaped constriction at the bottom, and an on-off valve on the bottom surface (eg,). See Patent Documents 1 and 2). When the powder or granular material contained in such a container is discharged, the on-off valve provided on the bottom surface is opened so that the powder or granular material is discharged by the natural flow of the powder or granular material.

Conventional container on-off valves open and close the discharge port by moving the cone valve suspended inside the container up and down, and open and close the discharge port by rotating a butterfly valve rotatably formed in the discharge port. There are known things that do.
Of these, the butterfly type on-off valve, which opens and closes the outlet of the container by rotating the butterfly valve, is widely used as an on-off valve for a container because of its simple mechanism and easy maintenance (for example, Patent Documents). See 3).

However, since the butterfly valve type on-off valve used in the conventional container needs to apply a relatively large rotational force in the opening / closing operation, there is a problem that the opening / closing operation is not easy in the case of the manual opening / closing type.

On the other hand, when the butterfly valve type switchgear is automatically opened and closed using an on-off device or the like, the operation handle of the on-off valve is accurately positioned and held, and this operation handle is rotated in one direction to open the on-off valve. It was necessary to use an automatic switchgear with a complicated structure equipped with a robot arm or the like capable of performing precise movements such as rotating in the opposite direction to close the switchgear. In addition, when using a butterfly valve equipped with a pneumatic or electric actuator, which is generally used as an automatic opening / closing valve, for a moving container, it is necessary to automatically attach / detach the air piping and electrical wiring, and in this case as well, these are accurate. Positioning is required. It is necessary to prepare a container equipped with such an automatic opening / closing valve and an operation handle having a special shape, and there is also a problem that the cost of the container is increased.

Further, it is difficult to manually operate the operation handle having a special shape adapted to the automatic operation of the on-off valve, and there is also a problem that the on-off valve is difficult to operate when the automatic switchgear is not used. ..

The present invention has been made in view of the above circumstances, and is a container provided with an on-off valve device capable of both opening and closing using an automatic opening and closing device and manually opening and closing, and an on-off valve device with a simple configuration. It is an object of the present invention to provide a container discharge device provided with an on-off valve operating device capable of opening and closing.

That is, the container of the present invention has the following configuration.
A container body having a discharge port on the bottom, a valve body that opens and closes the discharge port, a valve shaft that rotatably supports the valve body, and two operation pieces arranged apart from each other on the outside of the valve shaft. The valve shaft includes an on-off valve device having a coupling member for connecting the valve shaft and the two operating pieces, and the on-off valve device has the valve shaft at at least one of an open position and a closed position of the valve body. The valve body is opened by fitting a urging ball into a ball receiving hole formed on the outer surface of the container body, which is provided with a lock member for suppressing the rotation of the valve body. Locked at at least one of the position and the closed position, the coupling member is attached to the end of the valve shaft and extends in a direction perpendicular to the axis of the valve shaft, and the disc. It is characterized in that it is composed of a plate-shaped member extending from the outer peripheral portion of the shaped member toward each of the two operating pieces and to which the operating piece is fixed to the tip, and the lock member is formed on the plate-shaped member. And.

According to the container of the present invention, the two operation pieces are connected to the valve shaft that rotatably supports the valve body by connecting the two operation pieces arranged apart from each other via the coupling member. By simply extending upward, one valve shaft can be rotated in opposite directions to each other, and the outlet of the container can be easily closed and opened.

Further, according to such a container, the discharge operation can be automatically performed at low cost only by installing an on-off valve operating device having a simple structure provided with two telescopic arms. Further, the container can be easily operated even if it is manually opened and closed by using one operating piece for opening the valve body and the other operating piece for closing the valve body.

In addition, a commercially available inexpensive butterfly valve can be used as the valve body without using a specially shaped on-off valve device that supports automatic opening and closing of the valve body, and a container that supports automatic opening and closing of the valve body can be used at low cost. Can be manufactured in. In addition, a container that can handle both automatic opening and closing operations and manual opening and closing operations using an on-off valve operating device can be realized.

Further, in the present invention, the operation piece is a rod-shaped member extending parallel to the axis of the valve shaft.

Hereinafter, a container and a container discharge device including an on-off valve operating device according to an embodiment to which the present invention is applied will be described with reference to the drawings. It should be noted that the embodiments shown below are specifically described in order to better understand the gist of the invention, and are not limited to the present invention unless otherwise specified. In addition, the drawings used in the following description may be shown by enlarging the main parts for convenience in order to make the features of the present invention easy to understand, and the dimensional ratios of the respective components are the same as the actual ones. Is not always the case.

FIG. 1 is a plan view showing a container discharge device (hopper device) including a container and an on-off valve operating device according to an embodiment of the present invention.
The container discharge device 10 includes a container 20 of the present invention for accommodating powders and granules, which is an example of contained matter, an on-off valve operating device 30 for operating the on-off valve device 50 of the container 20, and the on-off valve operating device 30. It includes a pedestal 40 that can be attached and detachably supports the container 20, and an automatic control device 60 (see FIG. 6). The container 20 may be a liquid or the like as well as a powder or granular material.

The container 20 includes a tubular portion 21, a funnel-shaped cone 22 whose diameter is gradually reduced from the tubular portion 21 toward the discharge port 23 arranged in the center of the container 20 in a plan view, and a top plate covering the upper part of the tubular portion 21. A container main body 25 having 24 and an on-off valve device 50 formed in a discharge port 23 at the bottom of the container main body 25 are provided.

The tubular portion 21 of the container 20 has a square tubular shape in the present embodiment. Further, the pyramid portion 22 has a quadrangular pyramid shape composed of four surfaces inclined from each surface of the tubular portion 21 forming the square cylinder toward the discharge port 21. In addition to the quadrangular cylinder and the quadrangular pyramid, the tubular portion 21 and the conical portion 22 of the container 20 can be formed into a cylindrical shape and a conical shape, respectively, as in the present embodiment. Further, it can be formed into a polygonal cylinder shape or a polygonal pyramid shape, and the outer shape of the container body 25 is not limited.

The discharge port 23 has, for example, a circular opening, and a shooter 41, which will be described later, is connected to the discharge port 23 when the powder or granular material M housed in the container body 25 is discharged.

FIG. 2 is an enlarged schematic view of a main part showing an on-off valve device of a container.
The on-off valve device 50 includes a valve body 51 that opens and closes the discharge port 23, a valve shaft 52 that rotatably supports the valve body 51, and one operation piece 53 arranged apart from each other on the outside of the valve shaft 52. It also includes a coupling member 55 that connects the valve shaft 52 and the two operating pieces 53, 54 with the other operating piece 54.

The valve body 51 is, for example, a disk-shaped butterfly valve capable of closing the circular discharge port 23, and a valve shaft 52 extending parallel to the surface direction is fixed to the valve body 51. Such a valve body 51 has a closing position V1 (solid line in FIG. 2) that closes the discharge port 23 by rotating the valve shaft 52 by 90 ° and an open position along one surface of the valve body 51 in the vertical direction. It is made displaceable with V2 (chain line in FIG. 2).

At the closing position V1, the valve body 51 closes the discharge port 23 to prevent the powder or granular material M housed in the container body 25 from flowing out from the discharge port 23. Further, in the valve body 51, at the open position V2, one surface of the valve body 51 stands up along the vertical direction, so that the discharge port 23 is opened in a region excluding the thickness of the valve body 51, and powder particles are formed. Allows the outflow (excretion) of body M. The open position V2 of the valve body 51 also includes a half-open state in which one surface of the valve body 51 is inclined in an angle range of less than 90 ° with respect to the vertical direction.

The coupling member 55 is attached to one end of the valve shaft 52, and has a disc-shaped member 56 that extends in a direction perpendicular to the axis O of the valve shaft 52 and one operating piece from the outer peripheral portion of the disc-shaped member 56. It is composed of plate-shaped members 57a and 57b extending toward 53 and the other operation piece 54, respectively.

The operation pieces 53 and 54 are formed of cylindrical rod-shaped members that are fixed to the tips of the plate-shaped members 57a and 57b and extend parallel to the axis O of the valve shaft 52, respectively.

In the on-off valve device 50 having such a configuration, the valve body 51 rotates from the closed position V1 to the open position V2 by lifting one of the operating pieces 53 upward as shown in FIG. Further, by lifting the other operation piece 54 upward as shown in FIG. 4, the valve body 51 rotates from the open position V2 to the closed position V1.

The plate-shaped member 57b is formed with a lock member 58 that suppresses the rotation of the valve shaft 52 at the closing position V1 of the valve body 51. The lock member 58 is composed of, for example, a ball plunger, and when the other operation piece 54 is at the upper side shown in FIG. 4, the urging ball of the ball plunger is fitted into the ball receiving hole formed on the outer surface of the container body 25. By matching, the valve body 51 is locked at the closing position V1. This prevents the valve body 51 from rotating toward the open position V2 due to vibration during movement of the container 20, for example, and the powder or granular material M unexpectedly flowing out.

With reference to FIG. 1 again, the on-off valve operating device 30 automatically operates the on-off valve device 50 of the container 20 having the above-described configuration, and the first telescopic arm 31 and the second telescopic arm 32. And a frame body 33 that supports the first telescopic arm 31 and the second telescopic arm 32.

In the embodiment of FIG. 1, the on-off valve operating device 30 is installed below the on-off valve device 50, but as shown in FIG. 14, the on-off valve operating device 30 is installed on the side of the on-off valve device 50. You can also do it. In FIG. 14, the members corresponding to the members of FIG. 1 are assigned the same number.
Hereinafter, an example in which the on-off valve operating device 30 shown in FIG. 1 is installed below the on-off valve device 50 will be described.

The first telescopic arm 31 and the second telescopic arm 32 can be expanded and contracted between the extended position and the retracted position, respectively, and are expanded and contracted by, for example, an air cylinder. The first telescopic arm 31 and the second telescopic arm 32 are extended by injecting compressed air into the air cylinder, and the air inside the air cylinder is compressed by compressing the respective telescopic arms 31 and 32 from the outside. Is discharged and degenerates.

The second telescopic arm 32 is preferably formed so that the telescopic force is larger than that of the first telescopic arm 31. That is, as the air cylinder of the second telescopic arm 32, a cylinder having a larger capacity than that of the air cylinder of the first telescopic arm 31 is selected.

As the telescopic means of the first telescopic arm 31 and the second telescopic arm 32, for example, a hydraulic cylinder, an electromagnetic solenoid, a linear motor, or the like can be used in addition to the air cylinder.

The first telescopic arm 31 and the second telescopic arm 32 are rotatably supported with respect to the frame body 33. In the present embodiment, the first telescopic arm 31 and the second telescopic arm 32 are oriented in a direction perpendicular to the axis O (see FIG. 2) of the valve shaft 52 of the container 20 by the rotation axis formed on the frame body 33. It is axially attached to the frame 33 so as to be rotatable along a certain angle range. Further, the first telescopic arm 31 and the second telescopic arm 32 are positioned so that their longitudinal directions are along the vertical direction by means of urging means (not shown) such as a coil spring in a state where no stress is applied. Is being urged to.

As a result, the first telescopic arm 31 and the second telescopic arm 32 can be expanded and contracted in a direction inclined from the vertical direction in an angle range of, for example, 45 ° or less with respect to the vertical direction.

Operation piece engaging members 34 and 35 are provided at the tip portions of the first telescopic arm 31 and the second telescopic arm 32, respectively. The operation piece engaging members 34 and 35 have a bifurcated shape that extends along the expansion / contraction direction of the first expansion / contraction arm 31 and the second expansion / contraction arm 32.

When the first telescopic arm 31 and the second telescopic arm 32 are extended, the operating pieces 53 and 54 constituting the on-off valve device 50 of the container 20 are sandwiched by the operating piece engaging members 34 and 35 having such a bifurcated shape. Will be done.

The gantry 40 is formed by joining a frame made of, for example, a steel material, and supports the container 20 at the upper portion. Further, a frame body 33 that rotatably supports the first telescopic arm 31 and the second telescopic arm 32 of the on-off valve operating device 30 is fixed to the upper part of the gantry 40.

The gantry 40 is formed with a shooter 41 that is detachably connected to the discharge port 23 of the container 20 and guides the powder or granular material M discharged from the container body 25. The shooter 41 has a vertical movement mechanism 42 and a telescopic tube 43. The vertical movement mechanism 42 includes, for example, an air cylinder or a hydraulic cylinder, and expands and contracts the expansion / contraction pipe 43 along the vertical direction. The telescopic pipe 43 is made of, for example, a stretchable bellows pipe, and a connecting portion 43a forming one end thereof is formed so as to be in close contact with the discharge port 23 of the container 20. The expansion tube 43 guides the powder or granular material M discharged from the container 20.

The shooter 41 having such a configuration has a vertical movement mechanism 42, as shown in FIG. 1, a separated position where the connecting portion 43a of the telescopic pipe 43 is retracted downward from the discharge port 23 of the container 20 supported by the gantry 40. As shown in FIG. 3, the connecting portion 43a of the telescopic pipe 43 is formed so as to be displaceable from the connecting position connected to the discharge port 23 of the container 20.

Further, as shown in FIG. 5, a shooter valve 45 is formed in the vicinity of the shooter 41. The shooter valve 45 has a position of closing one open end of the telescopic tube 43 (position T1 in FIG. 5) and a position of retracting from the telescopic tube 43 (position in FIG. 5) at the separated positions of the telescopic tube 43 shown in FIG. It is rotatably formed with T2). When the container 20 is removed from the gantry 40, the shooter valve 45 rotates to a position where it closes one open end of the telescopic tube 43, so that the open end of the telescopic tube 43 is exposed and foreign matter or the like flows into the shooter valve 45. To prevent that.

As shown in FIG. 6, the automatic control device 60 includes a shooter detection sensor 61 arranged near the connection portion between the shooter 41 and the discharge port 23 of the container 20, and a first telescopic arm 31 of the on-off valve operating device 30. And a control unit 62 that controls the expansion and contraction of the second expansion and contraction arm 32.

The shooter detection sensor 61 detects the connection between the expansion tube 43 of the shooter 41 and the discharge port 23 of the container 20, and outputs a connection detection signal to the control unit. As such a shooter detection sensor 61, various sensors such as a mechanical sensor that detects the movement of the detection piece and an optical sensor that uses visible light or infrared light can be used.

The control unit 62 is composed of, for example, a boat microcomputer, a control interface, and the like. For example, the control unit 62 receives a detection signal from the shooter detection sensor 61 and controls the on-off valve operating device 30 to open and close the discharge port 23 of the container 20. The control unit 62 also controls the vertical movement mechanism 42 of the shooter 41 and the shooter valve 45 (see FIG. 5). Instead of the shooter detection sensor 61, a control signal may be output to the control unit 62 when the vertical movement mechanism 42 of the shooter 41 is completely raised.

The operation of the container discharge device 10 including the container 20 and the on-off valve operating device 30 having the above configuration will be described.
7 to 12 are enlarged perspective views of main parts showing the movement of the container discharge device including the container and the on-off valve operating device.
When the powder or granular material M is discharged from the container 20 containing the powder or granular material M inside, the container 20 is discharged from the container 20 in a state where the expansion pipe 43 of the shooter 41 is retracted and separated (see FIG. 7). It is placed at a predetermined position on the gantry 40 of 10 (see FIG. 8). When the container 20 is placed on the gantry 40, the control unit 62 of the automatic control device 60 starts the discharge control program. The discharge control program of the automatic control device 60 may be started automatically by a sensor that detects the placement of the container 20 on the gantry 40, or manually after the container 20 is placed on the gantry 40. Can be done.

First, the automatic control device 60 operates the vertical movement mechanism 42 of the shooter 41 to extend the telescopic tube 43 toward the discharge port 23 of the container 20 to bring it to the connection position (see FIG. 9). When the connecting portion 43a of the expansion tube 43 is connected to the discharge port 23 of the container 20, the shooter detection sensor 61 outputs a detection signal to the control portion 62.

When the shooter 41 is connected to the discharge port 23 of the container 20, the control unit 62 of the automatic control device 60 rotates the valve body 51 of the on-off valve device 50 from the closed position V1 to the open position V2. First, the automatic control device 60 extends the first telescopic arm 31 from the degenerate position (see FIG. 9) toward the extension position (see FIG. 10).

At this time, the first telescopic arm 31 sandwiches the cylindrical rod-shaped operating piece 53 of the on-off valve device 50 by the bifurcated operating piece engaging member 34. Then, the valve shaft 52 of the container 20 extends from the degenerate position to the extension position while rotating in the clockwise direction in the drawing. Since the operation piece 53 is connected to the valve shaft 52 via the coupling member 55, it moves in an arc shape, but since the first telescopic arm 31 is rotatably supported by the frame body 33, it can be operated. It can be extended while changing the angle from the vertical direction following the movement of the piece 53.

Further, at the start of extension of the first telescopic arm 31, the first telescopic arm 31 is urged to stand upright in the vertical direction, so that it extends in the vertical direction. Even if the installation position on the 40 is slightly deviated and the initial position of the operation piece 53 is slightly deviated from directly above the first telescopic arm 31, the operation piece engaging member 34 is formed in a bifurcated shape, so that it can be expanded and contracted. The arm 31 can be securely engaged with the operation piece 53.

Further, at the start of extension of the first telescopic arm 31, the valve shaft 52 rotates against the bias of the ball plunger of the lock member 58 formed on the plate-shaped member 57b constituting the coupling member 55. start.

As shown in FIG. 10, when the first telescopic arm 31 is extended to the extended position, the valve shaft 52 is rotated by about 90 ° via the coupling member 55 due to the ascent (rotation) of the operation piece 53. Due to the rotation of the valve shaft 52, the valve body 51 is displaced from the closing position V1 that closes the discharge port 23 toward the opening position V2 that has one surface of the valve body 51 along the vertical direction. As a result, the powder or granular material M contained in the container 20 is discharged from the open discharge port 23 through the expansion pipe 43 of the shooter 41. The discharged powder or granular material M may be introduced into, for example, a storage tank or the like.

As shown in FIG. 11, the first telescopic arm 31 supplies compressed air to the degenerate operation side of the air cylinder while discharging the powder or granular material M from the container 20. 31 is compressed to the retracted position to prepare for the next operation. By setting the inside of the air cylinder of the first telescopic arm 31 to be in an open state in which it communicates with the outside air, the first telescopic arm 31 may be compressed to a degenerate position by its own weight.

After completing the discharge of the powder or granular material M from the container 20, the automatic control device 60 then extends the second telescopic arm 32 from the degenerate position (see FIG. 11) to the extension position (see FIG. 12). As for the timing of extending the second telescopic arm 32, the completion of discharge of the powder or granular material M is automatically detected by a sensor or the like, or the completion of discharge of the powder or granular material M is visually confirmed and manually started and input. can do.

The second telescopic arm 32 sandwiches the cylindrical rod-shaped operating piece 54 of the on-off valve device 50 by the bifurcated operating piece engaging member 35. Then, the valve shaft 52 of the container 20 extends from the degenerate position to the extension position while rotating in the counterclockwise direction in the drawing. Since the operation piece 54 is connected to the valve shaft 52 via the coupling member 55, it moves in an arc shape, but since the second telescopic arm 32 is rotatably supported by the frame body 33, it can be operated. It can be extended while changing the angle from the vertical direction following the movement of the piece 54.

Further, at the start of extension of the second telescopic arm 32, since the second telescopic arm 32 is urged to stand up in the vertical direction, it extends in the vertical direction. Even if the position is slightly deviated from directly above the second telescopic arm 32, since the operation piece engaging member 35 is formed in a bifurcated shape, the telescopic arm 32 can be reliably engaged with the operation piece 54. ..

As shown in FIG. 12, when the second telescopic arm 32 is extended to the extended position, the valve shaft 52 is rotated by about 90 ° via the coupling member 55 due to the ascent (rotation) of the operation piece 54. Due to the rotation of the valve shaft 52, the valve body 51 is displaced from the open position V2 toward the closed position V1 that closes the discharge port 23. As a result, the discharge port 23 of the container 20 is closed by the valve body 51.

Further, when the second telescopic arm 32 reaches the extended position, the ball plunger of the lock member 58 formed on the plate-shaped member 57b suppresses the rotation of the coupling member 55, thereby closing the valve body 51. Lock at position V1. As a result, when the powder or granular material M is housed in the container 20 again, the valve body 51 rotates toward the open position V2 due to vibration or the like when the container 20 moves, and the powder or granular material M unexpectedly. It is possible to prevent the outflow.

After that, as shown in FIG. 13, for example, by supplying compressed air to the degenerate operation side in the air cylinder, the second telescopic arm 32 is compressed to the degenerate position, and the powder or granular material M of another container 20 is compressed. Prepare for discharge. By setting the inside of the air cylinder of the second telescopic arm 32 to be in an open state in which the inside of the air cylinder is communicated with the outside air, the second telescopic arm 32 may be compressed to the degenerate position by its own weight.

As described above, according to the container 20 of the present invention, two operation pieces 53, 54 arranged apart from each other via a coupling member 55 are provided on a valve shaft 52 that rotatably supports the valve body 51. By combining, one valve shaft 52 can be rotated in opposite directions only by extending the two operation pieces 53 and 54 upward, respectively, and the discharge port 23 of the container 20 can be easily closed and closed. It can be opened.

Then, according to such a container 20, the discharge operation of the powder or granular material M can be automatically performed at low cost only by installing the on-off valve operating device 30 having a simple configuration provided with the two telescopic arms 31 and 32. Can be done. Further, in such a container 20, one operation piece 53 is used for opening operation of the valve body 51, and the other operation piece 54 is used for closing operation of the valve body 51, so that the operation can be facilitated even if it is manually opened and closed. Can be done.

Further, a commercially available inexpensive butterfly valve can be used as the valve body 51 without using an on-off valve device having a special shape corresponding to the automatic opening and closing of the valve body, and the container 20 corresponding to the automatic opening and closing of the valve body can be used. It can be manufactured at low cost. Further, it is possible to realize a container 20 that can handle both an automatic opening / closing operation and a manual opening / closing operation using the on-off valve operating device 30.

According to the on-off valve operating device 30 of the present invention, it is only necessary to form a first telescopic arm 31 and a second telescopic arm 32 using an air cylinder and extend these two telescopic arms 31 and 32, respectively. , One valve shaft 52 of the container 20 can be rotated in opposite directions to each other. This makes it possible to easily automate the opening and closing of the discharge port 23 of the container 20 by the valve body 51 at low cost.

Further, the two telescopic arms 31 and 32 are rotatably attached to the frame body 33, respectively, and the operating piece engaging members 34 and 35 of the telescopic arms 31 and 32 holding the operating pieces 53 and 54 of the on-off valve device 50. By forming the two-pronged shape, the telescopic arms 31 and 32 can easily hold the operation pieces 53 and 54 at the time of extension even if the positions of the operation pieces 53 and 54 are slightly deviated. This eliminates the need for a highly accurate positioning mechanism when mounting the container 20 on the gantry 40, and makes it possible to realize automation of the on-off valve device 50 at low cost with a simple configuration.

Further, in operating the on-off valve device 50, in order to ensure that the discharge port 23 is closed by the valve body 51, the second telescopic arm 32 has a larger telescopic force than the first telescopic arm 31, that is, the capacity. By using an air cylinder having a large size, it is possible to realize a low-cost and space-saving on-off valve operating device 30 by applying an inexpensive first telescopic arm 31 having a small telescopic force.
