Description

  The present invention relates to a storage container that stores a storage object such as a powdery body or a granular body.

  As a conventional example of this type of container (container), for example, Patent Document 1 can be cited. In this case, a lid that covers the upper surface opening (hereinafter simply referred to as “opening”) of the container body is detachably mounted, so that the contents can be inserted into the container or discharged from the container. The lid is to be separated. Specifically, when storing the contents in the storage container, for example, after removing the lid from the container body and transporting it to the retracted position, a pipe for storing the contents is inserted from the opening, and the pipe is inserted through the pipe. The contents are put into the container body. When removing the contents from the container, remove the lid from the container body and transport it to the retracted position, and then place the container body in the upside down position with the opening facing downward. (See paragraph No. 0014 of Patent Document 1).

JP 2002-255104 A (paragraph number 0013, FIG. 2)

  In the storage container of Patent Document 1, it is necessary to carry and manage the removed lid to the retracted position, and the trouble of carrying and managing the cover is troublesome. In addition, the operation of taking out stored items from this type of storage container has been automated by an automatic discharge device. However, in the form of Patent Document 1, it is substantially impossible to cope with the automation. . That is, when an automatic discharge device is used, for example, the container is discharged after the container is opened upside down with the automatic discharge device opened in the upside down posture. In the form in which the lid is separated from the container body, the container is transported to a predetermined retracted position while preventing the lid from falling off while the container is falling because the container is placed in the upside down posture and the lid is separated. Therefore, it is difficult to handle the lid, and it must be said that it is unsuitable for an automatic discharge device.

  As a method for solving such a problem, for example, it is conceivable to support the lid so that the lid can swing in the outward opening direction. According to this, the opening of the container body can be opened by displacing the cover body from the closed position to the open position around the swing axis without separating the cover, and the cover is held by the container body. Therefore, time and labor for transporting and managing the lid are unnecessary. Further, since the container only needs to be turned upside down and the cover is simply swung from the closed position to the open position around the swing shaft, the opening can be easily opened.

  The problem with the outer lid as described above is that when the container is put into the container with the opening facing up, the lid rises obliquely, and the lid is used for loading the container. It is easy to interfere with the pipes and the like, and the insertion work of the pipes into the storage container cannot be smoothly performed.

  Apart from this, it is also conceivable to assemble the lid so as to be slidable in the horizontal direction. However, in this case, when the container is in an upside down posture, the weight of the container is almost entirely applied to the lid, and the container is easily caught between the lid and the periphery of the opening of the container body. It is difficult to slide smoothly.

  The present invention has been made in order to solve the above-described problems, and the lid is not obstructed when the contents are put into the container body, etc., and the loading work etc. can be carried out efficiently. It is another object of the present invention to provide a storage container suitable for an automatic discharge device that can open and close the lid reliably even when discharging the contents from the container main body in an upside down posture with the opening facing downward.

  As shown in FIG. 1, the container 1 according to the present invention includes a container main body 2 in which a container is stored, a lid 15 that seals an opening 5 provided on the upper surface of the container main body 2, and a lid 15. An opening / closing portion 6 is provided, which is slidable in the horizontal direction and supports the lid 15 so as to be swingable around the swing shaft 17, and closes the opening 5 in the horizontal direction. Between the three positions of the slide open position in which the opening 5 is opened by sliding and the swing open position in which the opening 5 is opened by swinging in the outward opening direction around the swing shaft 17 from the open position. The lid 15 is configured to be displaceable. The items contained here include powders, granules, liquids, and the like.

  Specifically, the opening / closing portion 6 is provided with a bearing portion 19 that supports the swing shaft 17 of the lid 15, and the peripheral wall of the bearing portion 19 is inserted into and detached from the swing shaft 17. When the swing shaft 17 is inserted and engaged with the bearing portion 19 and is pivotally supported, the lid body 15 can be displaced between a closed posture and a swing open posture. The rocking shaft 17 can be configured to be detached from the notch 29 when the lid body 15 is displaced from the closed posture to the slide open posture.

  The opening / closing part 6 is provided with a lock mechanism 16 for restricting the displacement of the lid 15 from the closed position to the swinging open position. The lock mechanism 16 rotates to the lock arm 23 and the lock arm 23. The lock arm 23 includes a roller 25 that is freely mounted. The lock arm 23 has a lock posture in which the roller 25 abuts against the lid body 15 and restricts the displacement of the lid body 15 from the closed posture to the swinging open posture. Is supported so as to be swingable about the horizontal axis 24 between the unlocked position allowing the displacement of the cover 15 from the closed position to the swinging open position, and in the normal state, the biasing means 26, when the cover 15 is displaced from the closed position toward the slide open position in the locked position, the roller 25 rolls and the cover 15 and the roller 25 are brought into contact with each other. Configured to release contact status It has been able to make that.

  The container body 2 is provided with a roller 25 on one end side of the lock arm 23 and an operation portion 23a on the other end side. When the operation unit 23a is pushed up, the lock arm 23 is displaced from the locked position to the unlocked position, and the lid 15 is configured to be displaced from the closed position to the swinging open position. .

  As shown in FIG. 4, the container body 2 has a funnel-shaped portion 2 b that narrows in a funnel shape toward the opening 5, and the inclination angle of a pair of inner surface portions that constitute the funnel-shaped portion 2 b is , Different angles can be set.

  Since the lid 15 can slide and move from the closed position that closes the opening 5 to open the opening 5, and can swing from the open position to the outward opening direction to open the opening 5. For example, when the container 15 is accommodated, the lid 15 is slid to open the opening 5 of the container body 2, so that the lid 15 rises obliquely and the container 5 is accommodated in the opening 5. It is possible to prevent the insertion pipe 39 from being obstructed and the like, and thus it is possible to reliably obtain good workability when accommodating the contents.

  Further, when taking out the contents in the container body 2, for example, the container 1 is placed upside down, the opening 5 of the container body 2 is set to the lower side, and the lid body 15 is swung in this state to By opening the upper surface opening 5, the lid body 15 can be moved more easily than when the lid body 15 is slid and moved, even if the container 15 is sandwiched between the lid body 15 and the periphery of the opening 5 of the container body 2. Thus, it is possible to reliably open the opening 5 of the container body 2 and discharge the contents. In addition, when the container 1 is placed in the upside down posture and the contents in the container body 2 are taken out, the contents of the container and the weight of the lid 15 can be combined to vigorously displace the lid 15 to the open position. It is also excellent in that it can effectively prevent the occurrence of malfunctions during the opening operation.

  When the cover 15 is displaced from the closed position to the slide-open position, if the swing shaft 17 is detached from the notch 29, the swing shaft 17 of the cover 15 is moved when the cover 15 is slid. Work such as removal from the bearing portion 19 can be omitted, and good workability when the lid 15 is slid to open the opening 5 of the container body 2 can be reliably obtained.

  When the roller 25 is brought into contact with the lid 15 to restrict the displacement of the lid 15 from the closed posture to the swinging open posture, for example, the opening 5 of the container body 2 is placed on the lower side in order to take out the contents in the container body 2. Even so, the lid 15 does not swing freely and does not open the opening 5 of the container body 2. That is, the opening 5 of the container main body 2 is prevented from opening unintentionally and the contents are prevented from falling. When the roller 25 is moved away from the lid body 15 to swing the lid body 15, the lid body 15 can be rocked to open the opening 5 of the container body 2 to discharge the contents. For example, when the lid 15 is slid and moved with the opening 5 of the container body 2 facing upward, the roller 25 rolls and the contact state between the lid 15 and the roller 25 is released. When the body 15 is slid, the operation of separating the roller 25 from the lid 15 can be omitted, and good workability when the lid 15 is slid can be reliably obtained.

  In the funnel-shaped part 2b, when the inclination angles of the pair of inner surface portions facing each other are set to different angles, for example, when the contents in the container body 2 are discharged with the opening 5 of the container body 2 facing down. In addition, the falling speed of the contained material falling along one inner surface portion is different from the falling speed of the contained material falling along the other inner surface portion, and the contained material is pressed and solidified near the opening 5 of the containing container 1. Clogging and the like are suppressed, and the contents in the container body 2 are discharged smoothly and quickly.

  1 to 5 show an embodiment of a storage container according to the present invention. The container 1 is transportable, and as shown in FIG. 3, a steel container main body 2 for storing a container such as a powdery body or a granular body, and the container main body 2 are surrounded.

The upper part (funnel-shaped part) 2b of the container main body 2 is formed in the shape of a quadrangular pyramid that narrows in a funnel shape toward the upper surface opening 5 side. That is, the upper part 2b of the container body 2 is arranged in an inclined shape in which the front, rear, left and right side plates 9, 10, 13, 14 (see FIGS. 4 and 5) are inclined inwardly of the container body 2, respectively.

  In addition, as shown in FIG. 4, the inner surfaces of any one of the pair of side plates 9 and 10 (the left and right side plates in FIG. 4) of the pair of side plates facing the front and rear and the left and right that constitute the upper portion 2 b of the container body 2 are The inclination angle d1 of the inner surface portion of the one side surface 9 (left side in FIG. 4) is larger than the inclination angle d2 of the inner surface portion of the other side plate 10 (right side in FIG. 4). That is, the inclination angles of the pair of inner surface portions facing each other are set to different angles.

  The inner surface portion of one side surface 9 in the upper portion 2b of the container body 2 has an inclination angle d1 of 70 to 80 degrees, for example, and the inner surface portion of the other side plate 10 has an inclination angle d2 of 50 to 60 degrees, for example. Have. Thereby, the upper surface opening 5 of the container main body 2 is formed at a position biased to any one of the front, rear, left and right peripheral sides of the container 1 (see FIG. 2). In addition, the other pair of side plates 13 and 14 in the upper part 2b of the container body 2 is inclined inward of the container body 2 at substantially the same inclination angle as shown in FIG.

  As shown in FIG. 1, the edge of the upper surface opening 5 of the upper part 2b of the container main body 2 is formed in a square tube shape, and the support plate 11 of the opening / closing part 6 is fixed to the upper end thereof. The support plate 11 is formed in a rectangular flat plate shape, and an opening 12 is formed at the center thereof so as to overlap the upper surface opening 5 of the container body 2. The opening / closing part 6 supports the lid 15 so as to be slidable in the horizontal direction, and to swing around the swing shaft 17. The opening / closing part 6 abuts on one edge 15a (left side in FIG. 1) of the support plate 11, the rectangular lid 15 and one of the front, rear, left and right edges of the lid 15, and the lid 15 A locking mechanism 16 that regulates the swinging of the lid, and a lateral swinging shaft 17 disposed on the other edge 15b of the lid 15 located on the opposite side (right side in FIG. 1) of the one edge 15a, A pair of bearing portions 19 and 19 are fixed to the upper surface of the support plate 11 and detachably support each axial end portion (see FIG. 5) of the swing shaft 17.

  The lid 15 of the opening / closing part 6 is formed with an annular groove 20 that bulges upward along the peripheral edge of the rectangle.

Next, the support arm 46 of the lid opening / closing mechanism 43 of the automatic discharge device 41 is swung downward, and the lid body 15 of the container 1 supported by the support arm 46 is swung downward by its own weight. That is, the lid body 15 is displaced from the closed posture to the swinging open posture, the upper surface opening 5 of the container main body 2 is opened, and the stored item falls and is discharged from the upper surface opening 5 by the weight of the stored item. The discharged contents are received by the hopper 49 or the like.

  At that time, since the upper part 2b of the container main body 2 has a funnel shape, all the contents in the container main body 2 are discharged smoothly and quickly. Further, the inclination angle d1 of the inner surface portion of the one side surface 9 facing the upper portion 2b of the container body 2 is different from the inclination angle d2 of the inner surface portion of the other side plate 10 facing each other, thereby along the inner surface portion of the one side surface 9. The fall speed of the fallen contents is different from the fall speed of the fallen contents along the inner surface portion of the other side plate 10, and the contained articles are pressed and clogged in the vicinity of the upper surface opening 5 of the receiving container 1. Is suppressed.

  When the container 1 of the container 1 is completely discharged, the support arm 46 of the cover opening / closing mechanism 43 of the automatic discharge device 41 is swung upward to close the cover 15 from the swinging open position to the closing position. The upper surface opening 5 of the container main body 2 of the container 1 is closed by the lid 15. In this state, the push-up rod 47 of the clamping release unit 45 of the automatic discharge device 41 is lowered. Then, due to the urging force of the tension spring 26 of the lock mechanism 16 of the container 1, the lock arm 23 swings and displaces from the unlocked position to the locked position, and the roller 25 of the lock mechanism 16 moves to one edge of the lid 15. It is pressed against the part 15a. Thereby, the closed posture of the lid 15 is maintained. Note that a hole 50 through which the push-up rod 47 of the clamping release portion 45 of the automatic discharge device 41 can be inserted is formed in the upper frame 3 a of the frame body 3.

  As described above, when the contents are accommodated in the container main body 2 of the container 1, the lid 15 is slid to open the upper surface opening 5 of the container main body 2. It does not obstruct the case of inserting the pipe 39 for storing the contents into the upper surface opening 5. Further, when taking out the contents in the container body 2 of the container 1, the lid body 15 is swung to open the upper surface opening 5 of the container body 2 of the container 1, so that the lid body 15 is slid. The upper surface opening 5 of the container body 2 of the container 1 can be opened by moving the lid 15 more easily.
