Description

  The present invention relates to a container that stores therein a granular material such as a mixed feed. In particular, the present invention relates to a container having a swing opening / closing type door, into which powder particles are charged and discharged via a hopper or the like.

Some containers that contain powdered bodies such as blended feeds have a swing opening / closing door (lid) that opens and closes the opening of the container body, and a lock mechanism that locks the door with respect to the opening.
FIG. 7 is a diagram showing an example of the structure near the opening of such a type of container. This figure shows a state in which contents are dropped and discharged from the upper container 101 into the lower hopper 150.
The container 101 includes a container main body 110 having an opening 111 for discharging / injecting into a hopper, a swing opening / closing type door 120 for opening and closing the opening 111, and a lock mechanism 140 for locking the door 120 to the container main body 110. Have.

  An abutting plate 115 projecting outward (horizontal direction) is provided on an edge around the opening 111 of the container body 110. When the contents are discharged from the container 101 to the hopper, the hopper opening seal is applied to the abutting plate 115.

  The door 120 has a shape that is slightly larger than the opening 111 of the container main body 110, and includes a central portion 121 and a peripheral edge portion 122 that rises from the periphery of the central portion 121. A packing 125 is disposed in a circumferential groove portion that opens to the inner side (container main body side) of the peripheral edge portion 122. As shown in FIG. 7B, the packing has a semicircular shape in which the cross-sectional shape of the tip is convex upward (inward) on the inner surface of the container body. The door 120 has a size that is slightly larger than the opening 111 of the container main body 110, and the packing 125 is applied to the contact plate 115 around the opening 111 of the container main body 110.

  The door 120 is attached to the contact plate 115 so as to be rotatable about a rotation shaft 132, and rotates between a closed position where the opening 111 is closed and a closed position where the opening 111 is opened.

  The lock mechanism 140 includes two U-shaped arms 141, a rotation shaft 142 that connects the base ends of both arms 141, and a tip shaft 143 that connects the tip ends of the lock mechanism 140. It is attached to the container main body 110 on the moving shaft side. The arm rotation shaft 142 is rotatably supported by a bracket that is fixed to a side surface on the back side (inner side of the container body) from the contact plate 115 of the container body 111. The arm 141 extends from the bracket through the opening 116 formed in the contact plate 115 to the outside of the contact plate 115 (on the container body opening side), and then extends to the opening 111 side. A roller 145 is rotatably attached to the tips of both arms 141.

  The arm 141 rotates inward (on the opening 111 side of the container body 110) around the rotation shaft 142, and the roller 145 presses the packing 125 of the door 120 against the contact plate 115; The roller 145 rotates to the outside (opposite to the opening 111 of the container body 110), and rotates between the unlocked position where the roller 145 is removed from the door 120.

An outwardly extending lever 144 is fixed to the rotating shaft 142 of the arm 141. The lever 144 is pushed up by an actuator (not shown). Then, the rotation shaft 142 rotates in the clockwise direction in the drawing, and the arm 141 fixed to the rotation shaft 142 also rotates in the clockwise direction, so that the roller 145 moves to the unlocking position that is removed from the door 120.
Further, the lever 144 is urged downward in the figure by a spring (not shown), and holds the arm 141 in the locked position.

  When discharging the contents from the container main body 110 to the hopper, first, as shown in FIG. 7A, the opening seal 151 of the hopper 150 is attached to one of the door 120, the lock mechanism 140, and the opening 116 of the backing plate 115. Place it around the outside. Here, the inside of the hopper 150 communicates with the outside through an opening 116 formed in the contact plate 115. Thereafter, while holding the door 120 with a cylinder (not shown) or the like, the lever 144 is pushed up to rotate the arm 141 to the unlocked position, thereby opening the door 120.

This type of container has the following problems.
(1) The arm 141 needs to sandwich the door 120 and the contact plate 115, and the contact plate 115 has an opening 116 through which the arm 141 passes. Then, when the opening seal 151 of the hopper 150 is applied to a position around the door 120 or the opening 116 of the contact plate 115, the inside of the hopper 150 is externally connected via the opening 116 formed in the contact plate 115. It will be in the state of communicating with. When the contents of the container 101 are discharged to the hopper 150 in such a state (further, there are a silo, a processing device, and a shipping container), the contents blown up through the opening 116 when the contents soar. There is a risk of blowing outside.

(2) As shown in FIG. 7B, when the packing 125 of the door 120 is pressed against the contact plate 115, there is a step S between the central portion 121 of the door 120 and the tip of the packing 125. . Then, as shown in FIG. 7C, the contents C may accumulate on the step S.

  When the above-mentioned “balloon” or “stack” occurs, the surrounding environment may become dirty, unsanitary due to the decay of feed, or mixing between lots of feed, etc., which may be undesirable.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a container in which the contents do not leak when discharged to the hopper or there is no space for the contents to accumulate in the door. And

A container serving as a base of the present invention includes: a container main body that contains powder particles and has an opening for discharging / injecting into the hopper; and a discharge hopper that protrudes outward from the periphery of the opening of the container main body. A contact plate to which an opening seal hits, a swing open / close door that covers the opening of the container body, and a lock mechanism that locks the door with respect to the opening, and the lock mechanism is attached to the contact plate. A slide member attached to be movable in the surface direction of the door; a roller attached to an end of the slide member so as to be rotatable; and a roller for pressing the door against the opening of the container body; and the slide member. , that Yusuke an actuator for moving between said rollers and an open position away from the door and a closed position for pressing the door, and a spring for urging the slide member in the closed position.

  According to the present invention, since the slide member moves in the surface direction of the door, it is not necessary to provide an opening / hole through which the slide member passes in the contact plate. Accordingly, it is possible to prevent leakage (blow-up) of the contents from the openings and holes when the contents are charged or discharged.

  Note that the portion of the door that is pressed by the roller of the slide member may be a door body or a block-like portion formed so as to protrude horizontally from the end face of the door.

  In this invention, packing is arrange | positioned at the opening of the said container main body, The recessed part of the depth which can be deform | transformed when the said packing is compressed is provided in the surface pressed by the said roller of the said door. Preferably, the roller is inserted into the recess when the door is closed.

  According to the present invention, when the roller rides on the door, the packing is compressed, after which the roller fits into the recess, and the packing slightly expands. At this time, the force of the packing makes it difficult for the roller to come out of the recess, and the door can be securely locked.

  In the present invention, the actuator is attached to the hopper, and when the opening seal of the hopper hits the contact plate of the container body, the actuator is engaged with the slide member, and then the actuator is driven. By sliding the slide member, the slide member can be slid to an open position where the roller is separated from the door.

  If the actuator is attached to the hopper, the actuator can be engaged with the slide member when the hopper hits the contact plate of the container body.

  As is clear from the above description, according to the present invention, since the opening / hole through which the arm of the locking mechanism passes is not formed in the backing plate, the container soared when discharging the contents of the container to the hopper. Leakage of contents to the outside can be prevented.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
With reference to FIGS. 1-4, the structure of the container which concerns on embodiment of this invention is demonstrated.
The container 1 contains a granular material, a container main body 10 having an opening 11 for discharging / injecting into a hopper, a swing opening / closing door 20 covering the opening of the container main body 10, and the door 20 as a container. And a lock mechanism 40 that locks against the main body 10.

The container body 10 includes a tapered truncated pyramid-shaped cone-shaped portion 10a and a rectangular box-shaped main accommodating portion 10b. A square opening 11 through which contents are input / extracted is formed at the tip of the conical portion 10a. Further, the weight-like portion 10a is provided with a vibrator mounting bracket 12 for vibrating the container 1.
When the contents are charged, the main housing portion 10b of the container body 10 is turned down. On the other hand, when the contents are discharged, the weight-like portion 10a (the opening 11 or the door 20 side) is turned down. The inclination angle of each side plate of the conical portion 10a preferably has an inclination equal to or greater than the repose angle of the granular material that is the content. By providing the inclination angle in this manner, the contents smoothly flow out toward the opening 11 along the side wall of the cone-shaped portion 10a when discharging in the posture with the cone-shaped portion 10a facing down. The contents do not remain.

  As shown in FIG. 2, the container body 10 is surrounded by a rectangular frame-shaped angle 13. This angle 13 is for reinforcing the container body 10 and for handling during transportation.

  As shown in FIG. 1, the container body 10 lies outward (horizontal direction) from the entire periphery of the opening 11 at a position slightly closer to the inside of the container body 10 (upper side in the figure) than the edge of the opening 11. The plate 15 is fixed. As will be described later, an opening seal 55 of the discharge hopper 50 is applied to the contact plate 15 (see FIG. 6). A bracket 16 that supports a rotation shaft 32 of the door 20 to be described later is fixed to a portion of the contact plate 15 outside the one side of the opening 11. In this example, as shown in FIG. 2, the bracket 16 is fixed at two locations near both ends of the same side.

  On the other hand, a lock mechanism 40 that locks the door and the container body is provided on a portion of the contact plate 15 opposite to the portion where the bracket 16 is fixed (details will be described later). In this example, the lock mechanisms 40 are provided at two locations near both ends of the door 20.

  The door 20 has a rectangular shape that is substantially the same size as the opening 11 of the container body 10, and includes a central portion 21 and a peripheral edge portion 22 that rises from the periphery of the central portion 21. The central portion 21 is provided with reinforcing ribs 24 over the entire surface. A packing 25 is disposed in the peripheral groove 22 that is open on the inner side (the container body 10 side). The packing 25 has a square cross-sectional shape, the inner surface (inner side of the container body 10) is flat, and is located on the same surface as the inner surface of the central portion 21. Since the door 20 and the opening 11 of the container main body 10 have substantially the same size, the packing 25 is applied to the edge of the opening 11 of the container main body 10 as shown in FIG. In addition, a hook 27 for opening and closing the door 20 is provided on the peripheral edge portion 22.

  One of the sides of the peripheral edge portion 22 of the door 20 is formed with an overhang portion 31 that protrudes horizontally outward. A rotation shaft 32 extending in parallel with the same side is fixed to the tip of the overhang portion 31. The rotary shaft 32 is rotatably supported by a bracket 16 fixed to the contact plate 15 of the container body 10. The door 20 rotates around the rotation shaft 32 between a closed position that closes the opening 11 and an open position that opens the opening 11.

Next, the lock mechanism 40 will be described with reference to FIGS.
The lock mechanism 40 includes a slide member 41 that is movably attached to the contact plate 15, a roller 42 that is rotatably attached to the slide member 41, and a spring 43 that biases the slide member 41. Is provided on the side opposite to the rotation shaft 32 (the side on the lock mechanism side). As described above, the lock mechanism 40 is provided at two locations near both ends of the side of the lock mechanism of the door 20.

  As shown in FIG. 2 (A), a slide shaft 45 is arranged on the outer side of the side of the locking mechanism of the door 20 of the contact plate 15 so as to be parallel to the same side, and both ends thereof are respectively The bracket 46 is fixed to the backing plate 15. As shown in FIGS. 2B and 2C, a slide member 41 is slidably attached to the slide shaft 45. The slide member 41 is a rectangular parallelepiped member, and includes a lower portion 41a and an upper portion 41b that are slidably fitted to the slide shafts 45. The slide member 41 slides on the same surface as the door 20 along the slide shaft 45 in parallel with the side of the lock mechanism of the door 20.

  As shown in FIG. 1B, a roller 42 is rotatably attached to the surface of the upper portion 41b of each slide member 41 on the door 20 side. The direction of the rotating shaft 42 a of the roller 42 is a direction orthogonal to the sliding direction of the slide member 41.

  As shown in FIGS. 2B and 2C, each slide member 41 is urged in the direction of one bracket 46 by a spring 43 fitted on the slide shaft 45. In this example, the slide members 41 are urged in opposite directions to abut on the outer bracket 46.

  On the other hand, as shown in FIG. 1B, a block-shaped protruding portion 29 protruding outward is provided on the side of the lock mechanism side of the door 20. Each protrusion 29 protrudes slightly before each slide shaft 45. The positions of the protrusions 29 correspond to the positions where the slide members 41 are urged by the springs 43 on the plane.

  At the position where the slide member 41 is urged by the spring 43, the protruding portion 29 and the roller 42 of the slide member 41 partially overlap on a plane. That is, at the position where the slide member 41 is urged by the spring 43, as shown in FIG. 3A, the roller 42 rides on the upper surface of the protruding portion 29, and the door 20 is moved with respect to the opening 11 of the container body 10. Are fixed. On the other hand, as shown in FIG. 3B, when the slide member 41 is slid away from the protrusion 29 against the biasing force of the spring 43, the roller 42 is separated from the protrusion 29 and the door 20 can be opened. It becomes.

  Further, as shown in FIG. 1B, the roller 42 and the protruding portion 29 partially overlap in the height direction of the container 1. The overlapping depth is such that it can be deformed when the packing 25 of the door 20 is compressed. As shown in FIG. 4, a concave shallow groove 29 a extending in a direction orthogonal to the sliding direction of the slide member 41 is formed on the upper surface of the protruding portion 29. The depth of the groove 20a is substantially the same as the overlapping depth. When the slide member 41 is urged in the direction of the protrusion 29 by the spring 43, the roller 42 first rides on the outer surface 29 b of the groove 29 a of the protrusion 29. At this time, the protruding portion 29 is pressed downward by the roller 42 to compress the packing 25, and the roller 42 can pass through the same surface. Thereafter, as shown in FIG. 4B, the roller 42 fits into the recess 29a, and the packing 25 extends to push up the door 20, that is, the protruding portion 29, so that the roller 42 and the protruding portion 29 are reliably engaged with each other. Therefore, the door 20 can be reliably held in the closed state.

  As described above, all the components constituting the lock mechanism 40 are accommodated in the space on the opening 11 side of the backing plate 15 (inside the portion where the packing 55 (see FIG. 6) of the hopper 50 contacts). Yes. That is, unlike the conventional example of FIG. 7, since the opening through which the arm 41 passes is not formed in the backing plate 15, there is no gap in which the content leaks when the content is discharged.

Next, the opening / closing operation and the locking operation of the door 20 will be described.
When the door 20 is closed, each slide member 41 is previously held at a position inward of the slide shaft 45 against the biasing force of the spring 43. Then, the door 20 is rotated about the rotation shaft 32, and the peripheral edge portion 22 is applied to the opening 11 of the container body 10. At this time, the packing 25 of the door 20 hits the edge of the opening 11 of the container body 10. Then, when the force holding the spring 43 is released, the slide member 41 is urged by the spring 43 and slides the slide shaft 45 outward, and rides on the protruding portion 29 of the door 20 as described above, and the groove 29a. Housed inside.

The operation of discharging the contents of the container 1 to the hopper will be described with reference to FIGS.
First, the structure of the hopper 50 will be described with reference to FIG. The hopper 50 includes a rectangular parallelepiped main body 51 and a support portion 52 in which a lower portion of the main body 51 is taken in and out. The main body 51 and the support portion 52 are connected by a connecting member 53. The main body 51 is supported by a lifting cylinder 60 so as to be movable up and down with respect to the support portion 52. A seal 55 (packing) is disposed around the opening of the main body 51. Further, a slide cylinder 70 for sliding each slide shaft 41 of the lock mechanism 40 of the container 10 is provided on each of the opposing side surfaces of the inner surface of the main body 51. A hook 71 is attached to the tip of the piston of the slide cylinder 70. In this example, the cylinders 70 are arranged at the same height position and attached so as to slide on the same straight line. Each cylinder 70 is controlled to be driven synchronously in a direction approaching and separating from each other.

  When discharging the contents of the container 10 to the hopper 50, first, the hopper 50 is positioned below the opening 11 of the container 10. At this time, the sliding direction of the sliding cylinder 50 of the hopper 50 is parallel to the sliding direction of the sliding member 41 of the locking mechanism 40 of the container 10, and the hook 71 of each sliding cylinder 70 is connected to each sliding member 41. Position it so that it is directly below. Then, as shown in FIG. 6A, the lifting cylinder 60 is driven to raise the main body 51 relative to the support portion 52, and the opening seal 55 is applied to the contact plate 15 of the container main body 10. At this time, the opening seal 55 is applied to the opening 11 of the container main body 10 and the contact plate 15 outside the slide shafts 41. In this state, there is no space or opening between the inside of the hopper body 51 and the container body 10. At the same time, the hook 71 at the tip of the piston of each slide cylinder 70 engages with the upper portion 41 b of the slide member 41 of the container body 10.

  Next, as shown in FIG. 6 (B), each sliding cylinder 70 is driven to move out the piston. Then, each slide member 41 engaged with the hook 71 at the tip end of the piston moves in the approaching direction along the slide shaft 45, and the roller 42 is moved to the protruding portion 29 of the door 20 as shown in FIG. Deviate from. Thereby, the lock of the door 20 is released, and the door 20 can be rotated about the rotation shaft 32. Actually, the hopper 50 is also provided with a door opening / closing cylinder (not shown) that opens while supporting the door 20 that can be turned.
