Description

  The present invention relates to a container for transporting a finely crushed product having a configuration in which the contents are stored and transported in a container body, the bottom of the container body is opened, and the contents are discharged.

  Various plastics, glass, paper, metal, etc. that can be reused are actively collected as so-called resources, and a system for collecting and recycling them has been established. The collected material is crushed into fine fragments, stored in a container as a finely crushed product, and transported. Conventionally, containers known as box-type pallets are used for the transportation, and when finely crushed products are brought in from the outside, they are put into the process from the input equipment such as a sorting line using a forklift. Is done.

  A pallet used for this type of transportation is generally, for example, one having a structure as disclosed in Japanese Patent Application Laid-Open No. 2002-160734. Is large but heavy. Since the bottom lid is configured to open as a whole in a heavy pallet, the force required to open and close the bottom lid that supports the heavy weight is large, and only one side of the box pallet is provided to open the closed bottom lid. It is necessary to operate the lever that is not. This lever can be operated while the person operating the forklift is still on the forklift, but care must be taken when a person at a lower position operates the lever. Moreover, depending on the positional relationship with the lever, for example, when the fork can be inserted into the pallet from four directions, two people, the driver and the operator, may be required, which is a work burden.

  In the case of a so-called box pallet, since the finely crushed product is filled in every corner of the cube or rectangular parallelepiped container body, the entire bottom surface must be opened to completely discharge the contents. For this reason, at the same time when the bottom cover is opened, the finely crushed product falls down with a tremendous momentum, and dust is scattered, resulting in a deterioration of the working environment. Further, in the case of a box pallet, if the bottom lid is opened in one direction, it cannot be completely opened if there is not enough space below it.

  The present invention has been made paying attention to the above points, and the problem is to provide a container for transporting a finely crushed product that can be easily operated by a lever for opening the bottom of the container body and discharging the contents. is there. Another object of the present invention is to provide a container for transporting a finely crushed product that does not cause deterioration of the working environment and can improve workability.

In order to solve the above-mentioned problems, the present invention stores a content in a container body and transports the container body as a container having a configuration in which the bottom of the container body is opened and the contents are discharged. And a frame that surrounds the container part and that bears the load of the entire container including the stored contents, and opens and closes the outlet provided in the container part. Are provided at the bottom of the container portion, and a plurality of bottom lid opening / closing mechanisms that are movable in the front-rear direction are provided between the bottom lid and the frame, and a plurality of ends of the bottom lid opening / closing mechanisms are pivotally supported by the frame. attached to the lever, and have a configuration which is connected with the lateral direction of the operating member the plurality of levers, the container portion has a smaller opening area than the top to bottom of the container portion, the lower portion Also has a large area Inclined parts that sag down the bottom of the container body are provided to guide the contents from the top of the container part toward the outlet with a small area, and the bottom lid opening and closing mechanism is provided at both the left and right ends of the bottom lid. A lock portion that can be engaged with the hook, a plurality of levers pivotally supported on the frame for linear movement of the lock portion, and a guide portion that converts the rotation into linear movement. The connecting rod is connected to a position that is pivotally supported by the frame and closer to the fulcrum than the center part of the lever length, and the connected point is the action point, and the operation member that connects the lever is the power point. Means is provided for performing a lever action for driving the lock portion .

  The container for transporting a finely crushed product according to the present invention particularly handles a crushed product of plastic or glass. For example, plastic pulverized products may contain useful metals such as gold and copper, so it is necessary to separate them. A finely crushed product is charged from a hopper provided outside the building.

  The container main body in the present invention includes a container part that stores the contents and a frame that surrounds the container part and bears the load of the entire container including the stored contents. Since it consists of a container part and a flame | frame, the room which provides a lever and the mechanism for the operation between them arises. In the present invention, the moving direction of the bottom lid is the front-rear direction, and the direction orthogonal thereto is the left-right direction. However, the orientation is merely for convenience of explanation and has no further meaning.

  In order to open and close the discharge port provided in the container part, a bottom cover is provided at the bottom of the container part, and a plurality of bottom cover opening / closing mechanisms movable in the front-rear direction are provided between the bottom cover and the frame, End portions of these bottom lid opening / closing mechanisms are attached to a plurality of levers pivotally supported on the frame, and the plurality of levers are connected using left and right operation members. The bottom lid is provided at the bottom of the container part, and it is desirable that the contents flow out from the large-area container part toward the small-area discharge port.

  The container part has the largest cross-sectional area at the top, and the outlet for discharging the contents has a smaller opening area than the upper part of the container part. In order to guide the contents toward the outlet, an inclined portion that is sunk downward in the container body is provided, and a space is set between the inclined portion and the frame surrounding the container portion. A bottom lid opening / closing mechanism is disposed at both left and right ends, and a left and right operation member is disposed in the space. Such a configuration is most desirable for achieving the object of the present invention because it prevents an excessive decrease in transport capacity and improves workability.

  As described above, the inclined portion sunk downward in the container body does not leave a finely crushed product and discharges smoothly, but by providing the inclined portion, the inclined portion and the container portion are provided. A space is generated between the frame surrounding the frame. Therefore, it is possible to provide a bottom lid opening / closing mechanism at both the left and right ends of the above-mentioned space, and to arrange the left and right operation members in the space. However, although the weight can be reduced by providing the inclined portion, it is also preferable to provide the inclined portion only on the two front and rear surfaces because the load amount of the contents is also reduced. Accordingly, the left and right two surfaces remain vertical, but even in that case, it is allowed to promote discharge by partially providing an inclined portion in the lower part.

  In addition, the above-mentioned bottom lid opening / closing mechanism includes a lock portion that can be engaged with hooks provided at both left and right end portions of the bottom lid, and rotation of a plurality of levers that are pivotally supported on the frame to linearly move the lock portion. It is possible to provide a guide part for converting the movement into a linear movement. The operation member that opens and closes the bottom plate in the entire area of the side surface of the container can be operated by the operation member in the left-right direction.

  Since the present invention is configured and operates as described above, the lever operation for opening the bottom of the container body and discharging the contents can be easily performed in the entire area of the side surface of the container. There is an effect that it becomes possible to improve. In addition, according to the present invention, it is possible to provide an inclined portion that is sunk downward from the upper part of the container portion having a large area toward the discharge port having a small area, and the contents can be guided. Since the product flows smoothly and does not fall and dust is not lifted up unnecessarily, it is possible to suppress deterioration of the working environment.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of a container 10 for transporting a finely crushed product according to the present invention, 11 is a container body, and the container body 11 is a container portion 12 for storing contents and the entire container including the contents. It is comprised from the flame | frame 13 which bears a weight. The container portion 12 in the illustrated example has a rectangular parallelepiped box shape as a basic shape, and inclined portions 15 and 16 which will be described later are provided on the lower portion. Therefore, the frame 13 surrounding the container portion 12 has a basic shape box shape. It has a rectangular parallelepiped structure that is slightly larger than that.

  As is apparent from the drawings, the container portion 12 has the largest cross-sectional area at the top, and the discharge port 14 provided at the bottom for discharging the contents is smaller than the top of the container portion 12. The opening area is narrowed to about one third of the length in the front-rear direction, and the contents are directed from the upper part of the large container portion 12 toward the small outlet 14. Inclined portions 15 and 16 are provided so as to be guided downward (see FIGS. 3 and 4). For convenience, when FIG. 2 is a front view of the container 10 according to the present invention, the direction perpendicular to the paper surface is the front-rear direction, the front is the front, and the left-right direction of the paper is the left and right of the container 10.

  The inclined portions 15 and 16 are provided on both the front and rear surfaces of the container portion 12, leaving an upper portion that is a fraction of the height of the rectangular box-shaped container portion 12 that is the basic shape. The left and right side surfaces are almost vertical. As the degree of the inclined portions 15 and 16, it is desirable that the rising angle from the horizontal plane is several tens of degrees, particularly about 40 degrees for smooth discharge of the contents. For the same purpose, the left and right side surfaces of the container portion 12 are also provided with small small slopes 17 and 18 at a part of the lower portion thereof. It can be said that it is composed of small slopes 17 and 18.

  In order to form a rectangular parallelepiped structure that is slightly larger than the basic shape box shape necessary for the structure surrounding the container portion 12, the frame 13 has a rectangular upper frame 19 and a lower frame 20 and vertical positions positioned at the four corners thereof. It has pillars 21, 22, 23, 24. The lower frame 20 includes a support frame 25 for supporting the forklift by a fork, a bottom frame 26 positioned at the lowest position, and a fork insertion port 27 (see FIG. 4). The fork insertion holes 27 are provided on the front, rear, left and right sides of the container 10 and have a structure that allows so-called four-way insertion.

  Further, the vertical columns 21, 22, 23, and 24 also serve as a support for stacking the containers 10 of the present invention. Therefore, the upper end portions are provided with convex portions 21a, 22a, 23a, and 24a, and the lower end portions are provided. In order to receive and support the convex portions 21a, 22a, 23a, and 24a at the upper end portion, concave receiving portions 21b, 22b, 23b, and 24b are provided. The receiving portions 21b, 22b, 23b, and 24b are formed in a concave shape that opens downward and outward, and have inwardly inclined wall surfaces, so that the work of placing the upper container 10 can be performed smoothly. it can. Reference numeral 28 denotes a reinforcing vertical frame, which connects the upper frame 19 and the lower frame 20 of the frame 13.

  In order to open and close the discharge port 14, a bottom lid 28 that is movable in the vertical direction is provided at the bottom of the container portion 12, and a bottom lid opening / closing mechanism that is movable in the front-rear direction between the container portion 12 and the frame 13. 32 and 33 are installed in two places on the left and right, respectively. The bottom cover 28 is pivotally supported by the lower frame 20 positioned below the discharge port 14 so as to be movable up and down by a support shaft 29 at an upper portion of the rear end portion, and has a certain angle when it is suspended when opened. As shown, an inclined wall 28b is formed on the rear surface, and a buffer material 28a is attached to the inclined wall 28b. A small wheel 30 is provided at the open / close end to smooth the ground movement, and a hook 31 locks the bottom cover 28 at a position to keep the discharge port 14 closed.

  The bottom lid opening and closing mechanisms 32 and 33 include a lock portion 34 that can be engaged with the hooks 31 provided at the left and right ends of the bottom lid 28, and a plurality of shafts that are pivotally supported on the frame 13 to move the lock portion 34 linearly. And a guide portion 36 that converts the rotation of the lever 35 into linear movement (see FIG. 8). The lock portion 34 is incorporated in a sliding portion 37 installed on each of the left and right sides of the frame 13 facing the discharge port 14 so as to be movable back and forth. The guide portion 36 includes a guide piece 38 installed in front of the sliding portion 37 in the moving direction, and includes a moving piece 39a and a moving piece 39a provided to move along the longitudinal guide groove 38a. A connecting rod 39 is provided at one end and attached to the lever 35 at the other end.

  The two left and right levers 35 are connected using a left and right operation member 40, and the operation member 40 has a length that covers almost the entire width of the container portion 12 in the left and right direction. And the space | gap 41 and 42 is set between the inclination parts 15 and 16 of the container part 12, and the flame | frame 13 surrounding the container part 12, and the bottom-lid opening-and-closing mechanism 32 and 33 is the one of the space | gap 41. Since left and right ends are arranged, the left and right operation members 40 that connect the left and right levers 35, 35 are arranged inside the space 41. The lever 35 is pivotally supported on the frame 13 by a support shaft 35a at the lower end, and a connecting portion 39b to the connecting rod 39 is located at a point closer to the fulcrum than the center of the lever length. Therefore, the operation member 40 is used as a power point, and a force due to the lever action is applied to the connecting rod 39 at the point of action.

  The container 10 of the present invention configured as described above is used when, for example, as shown in FIG. 9, the recovered plastic of the finely crushed product is input to the process from an input facility such as a sorting line by a forklift 43. Is done. In FIG. 9, the container 10 of the present invention is held at a required height by a forklift 43. In this state, the container 10 enters above the hopper 44 and stops, and the bottom lid 28 is opened. Since the container 10 is at a high position and the operation member 40 has a length that extends over almost the entire width of the container portion 12 in the left-right direction, when the operation member 40 is on the side of the operator 45 on the forklift 43, The operation of opening the bottom lid 28 while riding can be performed. When the operation member 40 is on the opposite side of the forklift 43, the operator 45 'on the line side performs an operation of opening the bottom cover 28. This operator may be a 45 'forklift driver or another person. When the operating member 40 is on the left and right of the forklift 43, an operator 45 riding on the forklift 43 can operate it, and can be operated by another person. In either case, the operation is very easy. .

  Since the operation member 40 has a length that covers almost the entire width of the left and right sides of the container 10, if the operation member 40 is operated in a random manner near the left and right ends in the above-described operation, the left and right levers 35 and 35 are evenly distributed. May be difficult to apply. In that case, if a difference in opening / closing force occurs between the left and right sides of the bottom lid 28, it is predicted that an obstacle to smooth opening and closing will occur. In the illustrated example, for this reason, the support shafts 35a and 35a are coupled to each other by a member 40 'parallel to the operation member 40, and the operation member is used as a rectangular frame to improve rigidity. It is preventing.

  In the container 10 of the present invention, the container part 12 has the largest cross-sectional area at the top, and the outlet 14 for discharging the contents has a smaller opening area than the top of the container part 12, so that it is charged. Since the finely crushed product is guided to the discharge port 14 at the inclined portions 15 and 16 of the container portion 12 and is smoothly discharged from the discharge port 14, the dust is hardly raised and the work environment is hardly deteriorated. . The finely crushed product put into the hopper 44 is conveyed to the sorting step by a conveying means 46 such as a screw feeder.

FIG. 9 described above also illustrates a state in which finely crushed plastic or the like is charged from another container 49 into the container 10 of the present invention. A container 46 is transported by a hoist 48 mounted on a building frame 47, and plastic or the like of a finely crushed product is charged into the container 10 of the present invention in which the upper surface is opened and the bottom lid 28 is closed. In the container 10 of the present invention, since the bottom lid 28 slides in the front-rear and lateral directions by the bottom lid opening / closing mechanisms 32, 33, even if there is not enough space below the discharge port 14, the deposits of finely crushed products The contents can be discharged without fear of touching 50 .
