Description

  The present invention relates to a cargo handling container suitable mainly for truck transportation, and a physical distribution system using the same.

The rationalization and efficiency improvement of the logistics system is always required from the viewpoint of reducing the environmental load, not just the shipper service. However, this method relies on the development of information infrastructure represented by so-called computer networks, and it cannot be said that the development of hardware to actually carry cargo is sufficient.
For example, in the case of containers, the relationship between overseas marine transportation, the handling facilities such as cranes in harbors and the cargo handling system using the same, and the road transport vehicle law and road traffic law concerning truck transport on land. As a result of various requests such as legal and regulatory relationships, the specifications of the container are naturally limited, and as a result, the idea that the current specification of the container is optimal is fixed or standardized, and further improvements are made. It wasn't done.

  Specifically, speaking of a so-called dry container 20 feet type of the most popular large container in Japan, it is about 5900 mm long x about 2350 mm wide x about 2380 mm high, and its own weight is about 2000 kg. With the maximum loading (about 22,000 kg), the strength of the container itself corresponding to the cargo handling work by a crane, a forklift or the like is required and can withstand this. In other words, the side panels and container floors that make up the container are required to have appropriate strength, and in order to satisfy the load capacity when lifting, the side panels are closed panels, and the height dimension is also the case of a fixed platform for trucks. The maximum ground clearance of 3800 mm, which is the same as the legal regulation value, is suppressed to the extent possible.

  For this reason, the volume of the cargo and the maximum load weight are subject to almost constant restrictions. In addition, with such a shape, the opening door for cargo handling work can only be provided at the rear, and when the container is transferred completely, once it enters the stage of land transportation In the truck terminal or the like, only the rear part of the container can be used as a loading / unloading port. From here, the cargo handling work can be continued by reciprocating work with a forklift or the like, and sufficient efficiency cannot be improved. Moreover, as long as such a handling method is assumed, it is necessary to install a loading platform facility at the lower edge of the opening at the rear of the container at the handling site, and manual handling operations are often required in the container. Yes.

  By the way, in actual cargo handling work, it is not always the case that the cargo with the maximum load weight is always stored in the container. Therefore, the present inventor does not necessarily need to always design the maximum loading weight for the container, and if there is a cargo with the maximum load, a structure that facilitates the unloading work separately. In that case, the inventors have found that there is room for improvement in the prior art with the focus that the cargo handling efficiency can be improved comprehensively. In addition, legally, this type of container is regarded as a load on a truck bed, so the fixed bed type truck is subject to legal restrictions. It is possible to select a dimensional specification up to a limit of 4100 mm above the ground, and found a room for securing a larger cargo space.

  The present invention has been made on the basis of such an idea, and is a container for cargo handling that can directly contribute to the improvement of cargo handling efficiency and transportation efficiency and can also reduce the environmental load as a result. The technical challenge is to develop a distribution system that uses the.

  The container for cargo handling according to claim 1 is a box-type container that is used by being loaded on a freight vehicle, and the container can be opened substantially at its rear and at least one side surface for handling work. It is characterized by being configured to be able to.

  In addition to the requirement described in claim 1, the container for cargo handling described in claim 2 is provided with a wing hatch for the opening structure of the side surface of the container, and this is provided on both the left and right side surfaces. It is characterized by being.

  The container for cargo handling according to claim 3 is designed to have a cargo handling load capacity of the container that is smaller than the weight of the cargo loaded with the maximum loading weight in addition to the requirements of claim 1 or 2. It consists of Here, the load-bearing capacity of the container refers to a load-bearing capacity when the container is lifted by a crane or the like, lifted by a forklift or the like, and further subjected to a load-handling operation such as support using a stand-like pedestal.

  The container for cargo handling according to claim 4 is characterized in that, in addition to the requirements of claim 1, 2, or 3, the height dimension of the container is in the range of 3800 mm to 4100 mm when loaded on the vehicle. It consists of.

  A logistics system using a cargo handling container according to claim 5 is a logistics system using the cargo handling container according to claims 1, 2, 3, and 4, and is loaded with cargo having a maximum loading weight. In some cases, the container is placed in a vehicle-mounted state and at least its side surface is opened to carry out the cargo transshipment operation.

  First, according to the first aspect of the present invention, even when the container is loaded on a freight vehicle, the cargo handling work can be performed from the side surface, the efficiency of the cargo handling work can be improved, and the flexibility of the construction of the cargo handling base can be selected. Some logistics work can be done. Further, even when the cargo owners of the cargo in the container move from one cargo handling site to another, a reasonable cargo handling operation is possible.

  In addition, according to the invention described in claim 2, since the opening of the side surface is sufficiently obtained and the wing hatch itself acts to elongate when opened, it is possible to avoid fouling of cargo even when it is raining outdoors. .

  According to the third aspect of the present invention, when the container accommodates the cargo with the maximum loading weight, the container of the cargo vehicle is used as a part of the strength member and the container is mounted on the vehicle. It is premised on the work of unloading the internal cargo as it is, and even when the content of the shipper and the cargo changes, flexible cargo handling corresponding to it is possible.

  According to the invention described in claim 4, since the container itself is also a cargo vehicle load, it is possible to set a maximum ground height of 4100 mm for legal purposes, and substantially set the height of the cargo compartment in the container to the maximum. Thus, a large capacity container can be obtained, which leads to a total reduction in the number of vehicles, and as a result, an environmental load can be reduced.

  Further, according to the invention described in claim 5, even when the container is loaded on the cargo vehicle, the cargo handling work can be performed from the side surface, the efficiency of the cargo handling work can be improved, and the structure of the cargo handling base can be selected flexibly. Logistics work can be done. Further, even when the cargo owners of the cargo in the container move from one cargo handling site to another, a reasonable cargo handling operation is possible.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention includes the embodiment described below, and also includes embodiments with various improvements based on this technical idea.

Hereinafter, the present invention will be described based on illustrated embodiments.
First, reference numeral 1 denotes a container according to the present invention, which is used by being loaded on a cargo vehicle such as a truck 2 in a state where a cargo (package) C is housed therein. Of course, the truck 2 includes a trailer type cargo vehicle towed by a semi-tractor in addition to the truck type defined in the claims.

  First, the container 1 will be described. This is a box-type container, and a container floor 11 is provided on the base surface. Although this container floor 11 has joists combined in an appropriate cross beam shape, the container floor 11 is not premised on carrying out a cargo handling operation such as lifting in the loaded state with the maximum loading weight as a whole, so the height is higher than that of the conventional type. Can be configured low. In addition, about this structure, the structure of Unexamined-Japanese-Patent No. 2004-322695 etc. with which this applicant is concerned can be applied suitably, for example. Of course, the container floor 11 may be a wooden deck laid on a steel deck plate having a folded plate structure.

  The container floor 11 has an elongated shape in plan view, and is formed so that the front panel 12 is raised on the front surface. On the other hand, a rear gate-type frame 13 is formed so as to stand up on the rear side facing this, and a ceiling beam 14 is provided near the center as an example between the front panel 12 and the rear gate-type frame 13. The rear gate-type frame 13 and the ceiling beam 14 including the container floor 11 become main strength members so as to maintain the strength of the container 1.

A wing hatch 15 that covers the side surface and the top surface of the container 1 is provided with the ceiling beam 14 as a support member and the pin 141 as a pivot point. This is integrated in the front-rear direction over a length corresponding to the longitudinal dimension of the container 1, bent 90 degrees from the top plate portion 151 connected to the pin 141, and laterally. And a side plate portion 152 that hangs down.
The wing hatch 15 itself is mainly composed of an appropriate combination of aluminum plates, aluminum aggregates, etc. In addition, when further weight reduction is required, a tent member having a waterproof function and the like is provided with a skeleton member as a pipe structure. It is possible to take a stretched configuration.

  Incidentally, referring to the shifter 155 for opening and closing the wing hatch 15, when the weight of the wing hatch 15 is possible by manual operation or the like, an opening / closing structure by manual winding, for example, a registered design involving the applicant of the present application. The structure disclosed in 1181082, No. 11811812, etc. can be taken. Of course, when using the power of a cylinder or the like, it is possible to shift by a hydraulic cylinder by connecting a hydraulic motor because the container 1 is a load, but more practically, from the main body of the truck 2 It is preferable to apply an electric motor cylinder that supplies power. In addition, about these, since there exists various existing means, detailed description is abbreviate | omitted.

The side plate 152 of the wing hatch 15 is set to be smaller than the height dimension H of the container, and a lower plate 16 is provided with a lower plate 16 that is opened and closed by a lower hinge type. The tilt plate 16 and the wing hatch 15 are closed by an appropriate latch structure. However, since well-known means can be adopted as appropriate for these, detailed description is omitted.
Further, the rear gate-type frame 13 is provided with a rear door 17. As an example, a door with a double door is applied.

  As defined in claim 4 of the present invention, the height of the container 1 of the present invention can be set sufficiently higher than that of the conventional container 1 '. That is, as shown in FIG. 4 and FIG. 5, the container 1 that is a cargo that is legally loaded is permitted to have a height of 4100 mm because the ground height dimension H1 is allowed up to 4100 mm in the loaded state. Dimensions can be taken. As a result, the room height dimension H0 of the conventional container of about 2660 mm can be set to about 2800 to 3000 mm, and a so-called high roof type container is realized.

Next, the truck 2 which is an example of the cargo vehicle carrying such a container 1 is demonstrated.
This does not require a special mechanism for receiving the container 1 of the present invention, and can be applied to a general flat platform truck 2. That is, a flat deck-like loading platform 22 is provided behind the driver's seat cabin 21, and a torii gate 23 for ensuring the safety of the driver's seat cabin 21 is provided at the front end of the loading platform 22.
Furthermore, since the height dimension H of the container 1 of the present invention can be set sufficiently high above the driver's seat cabin 21, it is preferable to provide a wind cowl 25 in consideration of air resistance.

The following cargo handling operation is performed by the combination of the container 1 and the truck 2 described above.
First, in a state where the container 1 itself is not mounted on the truck 2, the empty container 1 is lifted by the crane device 5 or the like and installed on the loading platform 22 of the truck 2. Of course, after installation, the container 1 is securely fixed to the loading platform 22 of the truck 2 using an appropriate clamp member. Even if you travel appropriately in such a state, the ground height H1 for legal regulations is 4100 mm or less, so there is no interference with structures on the road, such as pedestrian bridges, street lights, etc. Is possible.
The loading capacity at this time is increased to about 130% compared to the conventional container, and as a result, the transportation cost can be reduced and the environmental burden can be reduced.

After arriving at the cargo handling base in such a state, when the weight of the cargo C is so-called bulky, and when all the cargo is a single shipper, the container 1 and the crane device 5 It is possible to carry out cargo handling work such as lifting and storing.
In other cases, when the weight of the cargo is sufficiently heavy, or when the shipper has to move to a different handling base, the wing hatch 15 on the side surface of the container 1 or the rear door 17 on the rear surface is opened. The cargo C in the container 1 is loaded and unloaded using the forklift 3 or the like.
Of course, the fact that the forklift 3 can approach the container 1 from the side as described above is highly effective in streamlining the cargo handling operation. In particular, when the cargo C is loaded on the pallet P, a plurality of forklifts 3 can be approached from both the left and right sides, and the unloading work can be performed efficiently and rationally.

  In the case of long-term use, the service life of the relatively simple container 1 is longer than the service life of the truck 2 and the renewal time is different, but in the present invention, the container 1 continues as it is. It is possible to continue the transportation work by exchanging only the truck 2. When the so-called panel van type truck expires, the overall cost of equipment maintenance can be reduced compared to when the vehicle is completely replaced.

[Other Examples]
The present invention has the above-described embodiment as one basic form, but various modifications as described below are possible.
For example, the insulation material is incorporated in all parts such as the container floor 11, the front panel 12, the wing hatch 15, the tilt plate 16, and the rear door 17, which are specific members that divide the container 1, thereby improving the cooling function and the like. A container 1 can also be used.

Further, when the truck 2 itself is provided with a refrigerator unit (not shown), a cooling fin coil of the refrigerator or a cooling air supply duct for freezing is introduced into the container 1 so as to have a refrigeration function. It can also be set as a simple structure.
Of course, the refrigerator unit can be packaged compactly and mounted inside the container 1.
In addition to supplying power from the truck 2, the driving power itself can be applied to an independent internal combustion engine to drive the refrigerator.

  Furthermore, when the type, shape, etc. of the cargo itself to be transported are determined, there may be a form in which a rack or the like suitable for the cargo is incorporated in advance.

Furthermore, what is shown in FIG. 6 shows another embodiment of the method for transferring the container 1 to the truck 2. That is, the method already described is to lift the container 1 as shown in FIG. 1 and transfer it to the truck 2, but as shown in FIG. Work. Specifically, a pedestal attachment port 18A is formed on a side edge of the container 1 near the container floor 11 and an inverted L-shaped leg 18 is temporarily attached thereto. On the other hand, for example, the truck 2 incorporates an air suspension (not shown) having a vehicle height adjusting function.
Then, with the vehicle height of the truck 2 set to a regular dimension or a raised dimension, the pedestal 18 is set with respect to the container 1 at the cargo handling place, and then the air suspension of the truck 2 is contracted to bring the loading platform 22 of the truck 2 into place. The truck 2 is moved forward as it is so that the loading platform 22 passes through the lower surface of the container 1 so that the truck 2 and the container 1 are separated. Incidentally, when the container 1 is loaded on the truck 2, the reverse operation is performed.

  In the case of this embodiment, since the container 1 itself has a flat container floor surface 11 for supporting the cargo C, the loading platform 22 in the truck 2 is not necessarily found in the standard specification of the truck 2. It is not necessary to adopt such a flat deck type loading platform 22 (type shown in FIG. 1). For example, as shown in FIG. 6, it is possible to adopt a loading platform 22 made of a supporting member having a sufficient degree to support the container 1 according to the container 1. That is, a joist-like stay 27 is extended in a direction orthogonal to the ladder-shaped chassis 26 in the truck 2 so that the lower surface of the container 1 can be supported. In addition, in order to be able to perform such cargo handling work more reliably, it is also possible to employ, for example, the connection guide structure disclosed in the above-described Japanese Patent Application Laid-Open No. 2004-322695.
