Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container used for transporting a load and having a cargo handling device.

[0002]

2. Description of the Related Art In recent years, container transportation has increased in order to reduce transportation costs and packaging costs, shorten transportation periods, and prevent load pain. However, since the container is a box type and most of the containers have only one rear end, the crane cannot be used. Moreover, in order to improve the loading efficiency and prevent the cargo from collapsing, the cargo is loaded in bulk without any pallets and without gaps. For this reason, conveyors and forklifts can be used for transporting and transporting the load, but the removal of the load relies on manual work.

The unloading work of the container requires the work of transferring the load inside the container to the outside of the container, but in the case of loose articles such as chips, it is often a heavy work and it is a work safety. It is not preferable. In particular, with the aging of workers in recent years, there is a need for a cargo handling device that eliminates the work of back pain as a countermeasure for back pain. Conventionally, there is a crane that meets this condition, but it is not used in containers because it has the drawbacks that it is difficult to install in the container and the work speed is slow.

As a method of unloading chips from a container, as shown in FIG. 9, a platform 1, a hydraulic device 2,
It is also conceivable to provide an unloading device consisting of the cylinder 3, the overbang 4 and the weighing device 5.

The platform 1 tilts the container 8 up to 55 degrees by driving the hydraulic system 6 and the cylinder 7,
It is used for unloading, and is framed by shaped steel and steel plates and has sufficient width and strength for unloading the container 8, and one end thereof has sufficient strength for supporting the container 8 when the platform 1 is tilted. A back stop 9 as a locking device using a shaped steel is attached.

[0006]

Such a method of inclining the entire container on the platform 1 requires a large scale of the entire apparatus, and the unloading work cannot be performed unless the apparatus on the platform 1 is located. Moreover, in the course of a series of operations, if the next container enters while the overban 4 is open, it may fall into the receiving bin, and even if the rising position of the backstop 9 is not appropriate, it falls. It will be a serious disaster.

Japanese Unexamined Patent Publication (Kokai) No. 5-208731 discloses an automatic vertical table, a horizontal slide table,
A movable support frame that has a front and rear slide table, a gripping section, a conveyor upper and lower slide table, and a transfer section can be moved inside the container, and a conveyor section that connects to the transfer section is further equipped with an extension conveyor to position the load on each slide table. And the vacuum suction pad is operated to pull it out to the transport unit and move it on the conveyor.

The cargo handling device in a container disclosed in Japanese Unexamined Patent Publication No. 5-208731 has a large scale, which is problematic in terms of cost.

The object of the present invention is to solve the inconveniences of the above-mentioned conventional example, and to load the container without a pallet without gaps without major remodeling of the container and without providing a large-scale device outside or inside the container. It is possible to mechanize the unloading work or loading work, and to eliminate the heavy work of manual unloading, which allows unloading of containers, aging loaders, and improving work efficiency. It is to provide a container with a cargo handling device that can cope with improvement.

[0010]

In order to achieve the above-mentioned object, the present invention is, first of all, capable of moving back and forth by a cylinder on the bottom as a cargo handling device for discharging or loading cargo into a box which is an outer shell of a container. The floor plate is arranged on the floor plate, and the side portion can be locked to the box side on the floor plate. Only the floor plate moves at the time of locking, and the push wall moves together with the floor plate at the time of movement. The wall has an inclined surface whose lower part projects further forward. Thirdly, the locking of the push wall forms a rack portion on the box side, while the push wall only has one direction on the rack portion. The gist is that a locking cam is provided, and fourthly, the cam can reverse the locking direction with respect to the rack by its inclination.

Fifthly, the push wall is locked by forming a rail portion on the side of the box body, while the push wall is provided with a chuck mechanism by a cylinder for the rail portion. Forming an upper opening adjacent to this rear end opening by means of an opening / closing hatch in addition to the rear end opening provided with a double door
In addition, the floor plate that can be moved back and forth is characterized in that a portion of the rear end portion that goes out from the box body is bent or bent downward.

According to the present invention as set forth in claim 1, the container is provided with a cargo handling device, and can be used for unloading loads such as chips and other loose objects that are stacked in the container without a pallet without a gap. Can be mechanized. In addition, the container has a push wall that moves in the front-back direction as a load discharging device or a loading device in the box that is the outer shell, and in the case of discharging the load, chips and other loads are moved in the direction of the load discharging port by this push wall. It can be moved and discharged to the outside of the container, and in the case of loading, this push wall sends the load to the back side, without any major remodeling of the container, and without pallets inside the container without a large external device. It is possible to mechanize the unloading work or the loading work of the load that has been loaded.

The load such as chips is placed on the floor plate inside the box body of the container and moves backward together with this slide plate so that the load at the rear part goes out of the box body. At this stage, the cargo is on the floorboard, but if the floorboard is pulled forward while the front wall of the cargo is restrained by locking the push wall to the box side, the floorboard under the rear cargo disappears and falls.

The lock between the push wall and the box side is released, the load is moved backward together with the floor plate, and the subsequent operation is repeated to sequentially drop the load from the rear part.

Even if a cylinder is used to move the floorboard back and forth, its stroke may be small and small, and since the push wall does not push out the load such as chips, the strength of the cylinder itself and the side plate of the cargo bed can be reduced. The locking does not have to be so robust.

On the other hand, when used as a loading and unloading device, contrary to the above operation, the push wall is at the rearmost position, and the load such as chips is placed on the floor plate inside the container box in front of it. Later with this slide plate forward (back side of the box)
Go to and at this stage the load is on the floorboard. Push the floorboard backward while locking the push wall to the box side to suppress the front end of the load, then release the lock between the push wall and the box side, and move forward with the floor plate of the load, And the subsequent operation is repeated to sequentially move the load from the rear part to the front part.

According to the present invention as set forth in claim 2, in addition to the above-mentioned action, since the lower portion of the push wall has a slanted surface which projects downward, the lower portion of the push wall is wide for a while. A stable shape can be secured. Also, since the push wall is only placed on the floor plate and the fixation between the push wall and the floor plate relies on friction, there is a risk that the push wall will move if the load collapse force due to loose loads such as chips is applied to the push wall. There is.

When a load collapsing force due to this bulk load is applied to the inclined surface, it is dispersed into a force for pushing the pushing wall forward and a force for pushing the pushing wall downward, and by moving the floor plate and pushing wall together, the load is surely secured. Can be sent. Further, when the push wall is locked to the box side, only the floor plate under the load can be moved against the friction between the floor plate and the push wall.

According to the third aspect of the present invention, the left and right load carrier side plates of the load carrier and the push wall are continuously locked by the rack portion and the cam which is locked to the rack portion only in one direction. And it can be done easily.

According to the fourth aspect of the present invention, the cam can reverse the locking direction with respect to the rack by its inclination.
As described above, the push wall and the load are moved to the load discharge port, and the load can be discharged to the outside of the container, and the cam and the rack rail are engaged in the opposite direction to move the push wall to the back of the loading platform.
That is, in order to return the push wall moved to the load discharge port to the original position, similarly, the load on the floor plate and the push wall are moved together with the floor plate as the first step, and then the rack rail is set as the second step. The cam and the cam are in the locked state, the push wall is fixed, and only the floor plate moves in the direction of the load discharge port (outward direction). Thereafter, the first step and the second step are sequentially repeated, and the push wall is moved to the back of the loading platform. Can be moved to.

According to the fifth aspect of the present invention, the push wall is locked by forming a ridge on the box body side, while the push wall is provided with a chuck mechanism by a cylinder for the ridge. Therefore, the push wall can be locked to the box side as necessary regardless of the direction in which the floor plate moves back and forth.

According to the present invention of claim 6, the box body is
In addition to the rear end opening with a double door, an upper opening by an opening / closing hatch is formed adjacent to this rear end opening so that when loading a container into the container and sending it to the back, the load can be placed inside the container through the upper opening. If you put in, the push wall is at the rearmost position,
It is possible to place the cargo such as chips on the front side of the container on the floor plate inside the box body without any trouble.

According to the seventh aspect of the present invention, in the floor plate that can be moved back and forth, the rear end portion of the floor plate is bent or bent downward, so that the floor plate is rearward of the box body. It is not necessary to secure a space in the rear of the box that extends horizontally from the end, and a support stand and the like are not necessary, which is convenient even when a sufficient space cannot be obtained.

[0024]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of a container with a cargo handling device according to the present invention, FIG. 2 is a side view of the same as above, and 10 in the drawing shows a box which is an outer shell of the container, from a front end plate 10a, a side plate 10b, and the like. This is the box 10
The rear end is the rear end opening 11. Further, the rear end opening 11 has a door 14 that can be opened and closed by opening the double door.

There are cases where the roof material 10c is provided and cases where it is not provided. In the case where the roof material 10c is provided, in addition to the rear end opening provided with the double door 14 as shown in FIGS. An upper port 20 of 20a was formed adjacent to the rear end port 11.

The rear end opening 1 is not always necessary.
1 is an auxiliary door 1 at the bottom of a door 14 that opens and closes with a double door
9 may be provided.

According to the present invention, a pushing wall 12 that moves in the front-rear direction is provided in the box body 10 as a load discharging device or a loading device. Further, a floor plate (slide plate) 13 which is laid below the push wall 12 and is movable back and forth is laid.

The push wall 12 is made of steel, and the box body 10 is a rectangular parallelepiped and is arranged in a direction parallel to the rear end opening 11.
In addition, the push wall 12 has a partition plate 12b provided upright on the support plate 12a, and the lower part of the partition plate 12b has an inclined surface 26 whose lower portion projects further forward. Also, the floor board 13
Is also made of steel or stainless steel and may be relatively thin.

The push wall 12 is different from the floor plate 13 in the support plate 12a.
Is mounted only by contacting with each other. On the other hand, a reciprocating cylinder 15 is provided between the floor plate 13 and the box body 10 so that the floor plate 13 can be moved in the front-back direction.

Further, as fixing means 16 for fixing the push wall 12 to the box body 10, lock pins 17a as locking projections are provided on the inner side surface of the side plate 10b at appropriate intervals to provide the rack portion 1.
On the other hand, the push wall 12 is provided with a cam 18 which is locked to the stop pin 17a of the rack portion 17 only in one direction. The cam 18 is a pendulum type or seesaw type lock bar.

The cam 18 is rotatable by a shaft, and the inclination of the cam 18 makes it possible to reverse the locking direction of the rack portion 17 with respect to the stop pin 17a. That is, the rack portion 17
The pawl is provided at the end portion so as to be locked to the stop pin 17a only in one direction.

Next, the usage will be described. 3 to 5
Is a case of unloading the container of the present invention loaded on the trailer truck 27.
Assuming that there is a load A inside, the rear end opening 11 is opened. The push wall 12 is located near the front end plate 10a, and the cam 1
8 engages with the stop pin 17a of the rack portion 17 and the front end plate 1
Prevents movement to the 0a side.

When the cylinder 15 is extended, the floor plate 13 moves from the front end plate 10a side toward the rear end, and the load A of the floor plate 13 and the push wall 12 also move by that amount. In addition,
In this state, the relationship between the rack portion 17 and the cam 18 is such that the tip claw moves out of the continuous concave portion between the retaining pins 17a of the rack portion 17 and moves to the adjacent continuous concave portion, and the rack portion 1 shifts sequentially.
Since it moves along 7, the push wall 12 is not locked to the box 10.

Further, since the push wall 12 moves together with the floor plate 13, the load A can be reliably sent.

As a result of the sliding of the floor plate 13, the floor plate 13
The rear end of the rear end goes out from the rear end opening 11 with the load still loaded.
(See Figure 4)

Next, when the floor plate 13 is pulled toward the front end plate 10a side while the cylinder 15 is contracted, the claws of the cam 18 are locked and fixed to the stop pins 17a of the rack portion 17,
The push wall 12 is locked to the side of the box body 10, and the load A does not move as it is because the front end portion is fixed to the push wall 12, and falls because the floor plate 13 disappears outside the rear end opening 11.

When the load A is dropped, the push wall 12 is locked to the side of the box body 10, the cylinder 15 is extended again to push the floor plate 13 rearward, and thereafter, the push of the floor plate 13 and the push wall are performed. 12, locking of the floorboard 13,
By repeating the procedure of dropping the load and releasing the lock of the floor plate 13, all the loads A are dropped out of the box 10.

In order to prepare for loading again from the state where all the loads A are unloaded, the push wall 12 is moved to the front part of the floor plate 13 and the front end plate 10a side.

By the engagement of the rack portion 17 and the cam 18, only the movement of the cam 18 toward the front end plate 10a side is allowed, and the backward movement is prevented.

When the cylinder 15 is extended, the floor plate 13 moves from the front end plate 10a toward the rear end, and the pawl of the cam 18 is fixed by being locked to the stop pin 17a of the rack portion 17, and the push wall 12 is fixed to the box. It is locked on the side of the body 10 and only the floor plate 13 moves.

Next, when the floor plate 13 is pulled toward the front end plate 10a side while the cylinder 15 is contracted, the relationship between the rack portion 17 and the cam 18 in this state is that the pawl has a locking pin 17a.
Since the push wall 12 is not locked on the side of the box body 10, the push wall 12 on the floor plate 13 is correspondingly moved away from the push wall 12 by moving to the adjacent continuous concave portion and moving sequentially along the rack portion 17 while shifting. Just move.

Thereafter, the floor plate 13 is extruded and the pushing wall 1 is pushed.
The procedure of locking 2 and retracting the floor plate 13 and unlocking the floor plate 13 is repeated to move the push wall 12 to the front so that the inside of the box 10 becomes a space suitable for loading.

Loading of the load into the box body 10 is performed at the rear end opening 11
In addition to the above, if the upper opening 20 is provided by the opening / closing hatch 20a, it can be performed from here.

At this time, the push wall 12 can also be used as a load feeding mechanism. That is, the push wall 12 is placed close to the rear end opening 11 where the door 14 and the auxiliary door 19 are closed, and a load is put into this front side through the upper opening 20.

Similar to the operation of discharging the load, the floor plate 13 is pulled in, the push wall 12 is locked, the floor plate 13 is pushed out,
By repeating the procedure of moving the load to the back and unlocking the push wall 12, the loads directly below the upper port 20 are sequentially fed to the back, and when a space can be secured immediately below the upper port 20, again,
Load the load there.

In this way, it is possible to fill the inside of the box 10 with a load by loading a load just below the upper port 20, sending it, and repeating loading.

Next, as another embodiment, the box body 10
On the other hand, instead of the fixing means 16 for fixing the push wall 12, a fixing means 22 as shown in FIG. 3 may be used.

The fixing means 22 is formed by forming a rail-shaped protruding portion 23 on the side of the box body 10, while providing a chucking mechanism 25 by a cylinder 24 for the protruding portion 23 on the push wall 12. did. In this embodiment, the chuck mechanism 2
Reference numeral 5 has a rotating claw 25b with respect to the fixed claw 25a, which extends the cylinder 24 and pushes the rotating claw 25b toward the fixed claw 25a, so that the protrusion 23 is sandwiched between the fixed claw 25a and the rotating claw 25b. To wear. When the cylinder 24 is reduced or freed, the rotating claw 25b and the fixed claw 25a are separated from each other and the protrusion 2
Release the clamp to 3.

The method of use is the same as in the case of using the fixing means 16, and the floor plate 1 is fixed by the cylinder 15.
When 3 moves, this fixing means 22 is made free, and both the push wall 12 and the load placed on the floor plate 13 are fixed to the floor plate 13.
It is selected whether to move together with the floor plate 13 so as to be carried by or to fix the push wall 12 to the box body 10 side by the fixing means 22 and move only the floor plate 13.

The floor plate 13 which can be moved back and forth is
A portion of the rear end portion that goes out of the box body 10 may be bent or bent downward.

As a structure that bends or bends in this way, it is conceivable that the tip portion of the floor plate 13 is made flexible. For that purpose, a thin wall structure, a crawler belt structure, or a hinge structure is used. Various methods are conceivable, such as having a joint.
