Japanese Patent No. 3581985 JP2013-119415A

  In the transport apparatus and transport method described in Patent Document 1 and Patent Document 2, it is necessary to carry and unload the cargo with a transporter such as a forklift, a carriage, or a crane to at least the container entrance position that comes into contact with the slide member or the sliding plate. There is. For this reason, skilled labor having high technology capable of operating the transporter is required, which requires power and time.

  In addition, for containers with a ceiling, it is necessary to ensure an appropriate work interval between the container ceiling and the luggage, and thus there is a risk that the efficiency of the cargo loading space of the container will be diminished.

  Furthermore, in the conveyance device described in Patent Document 1, since it is necessary for all of the plurality of rolling elements to roll at the same time, the entire conveyance device is used when rolling is prevented due to dust or damage even at one place. May become impossible. In addition, once a problem occurs, maintenance requires advanced technology, labor, and costs, and the loss incurred by the entire physical distribution due to a delay in the transportation work is large.

  In the transport method described in Patent Document 2, the load side slide portion is brought into contact with the container side slide plate, and the inside of the container is slid and moved by pressing the side surface of the load. The method itself is not particularly novel.

  In this transport method, a flat plate made of a slippery material is used for the sliding plate on the container side, the sliding portion on the moving luggage side is shaped like a boat, the tip bites into the sliding plate on the container side, and the sliding property is Prevents being killed. Further, a lubricant such as grease is applied to the sliding plate and the sliding portion in order to improve sliding. However, such a device for improving slidability is not new.

  In the transport method described in Patent Document 2, since it is necessary to provide a special structure that is easy to slide on the bottom surface of the package or the container that stores the package, the conveyance method is limited to a package using a dedicated packaging tool or a dedicated container, It is difficult to obtain sufficient slidability for normal luggage.

  In addition, since the contact portion between the load and the sliding plate is a flat surface-to-flat contact, the sliding portion is sufficiently affected by the friction coefficient determined by the material, flatness, and other factors of the sliding plate and the sliding portion. It is difficult to obtain mobility.

  In view of the above facts, the present invention has an object to provide a loading / unloading apparatus, a loading method, and a loading / unloading method that can load or unload a package in a container without using a transporter. And

(First embodiment)
Hereinafter, a loading / unloading apparatus according to a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the loading / unloading device 10 of the present embodiment includes an accumulation base 12 with an adjustable inclination angle, a first plate member (plate member) 24 disposed on the top surface of the accumulation base 12, A second plate member (plate member) 28 that slides on the first plate member 24 and a loading platform 14 on which the second plate member 28 is disposed on the bottom surface are provided.

  The stacking table 12 has a top surface having an area substantially equal to the area of the floor surface of the container 40 described later. The stacking table 12 includes a support member 16 and a pair of hydraulic cylinders (angle adjusting mechanism) 18. And the support | pillar 20 and the extrusion board (extrusion mechanism) 22 are provided.

The support member 16 is erected on the base 15 and supports the central portion of the stacking table 12 so that the stacking table 12 can be tilted.
The hydraulic cylinders 18 are provided at both ends of the stacking table 12, the cylinder 18 </ b> A is rotatably connected to the base 15, and the rod 18 </ b> B is rotatably connected to the bottom surface of the stacking table 12. With this configuration, the inclination angle of the stacking table 12 is adjusted by expanding and contracting the rod 18B by hydraulic pressure.

  The support column 20 is a holding mechanism that is erected on one end of the top surface of the stacking table 12 and holds the load table 14 in an upright state so that the load table 14 placed on the top surface does not slide off from one end of the stacking table 12. . The support column 20 is detachable from the stacking table 12. When the loading table 14 is slid from the stacking table 12, the column 20 is removed from the stacking table 12 so that the loading table 14 does not interfere with sliding.

  The push-out plate 22 is guided by a rail (not shown) provided on the top surface of the stacking table 12 and is slidable with a light force toward the support column 20 side.

  As shown in FIG. 3, the first plate member 24 is a plastic plate made of polyacetal or the like in which a plurality of ribs 24A are arranged in parallel along the longitudinal direction of the plate surface. By connecting in the longitudinal direction, one long first plate member 24 is formed.

  The rib 24A is formed over the entire length of the first plate member 24, and the top is rounded to have an arcuate cross section. Four first plate members 24 are juxtaposed on the top surface of the stacking table 12 at intervals, and are attached to the top surface of the stacking table 12 with an adhesive or the like.

  The rib 24A has a shape that is linearly continuous from one end to the other end in the longitudinal direction of the first plate member 24, a shape that is discretely arranged in a chain line shape, a shape that is arranged in a dotted line shape, or a chain line shape. Any shape such as a combination of dotted lines may be used. Furthermore, the cross-sectional shape of the top of the rib may be an edge shape or a wedge-shaped shape, and can be appropriately selected in consideration of load resistance and slidability.

  The second plate member 28 is a plastic plate having the same shape as the first plate member 24 in which a plurality of ribs 28A are arranged in parallel along the longitudinal direction of the plate surface, and a single plate is formed by connecting a plurality of plastic plates. A long second plate member 28 is formed.

  Four second plate members 28 are arranged side by side along the longitudinal direction of the bottom surface of the loading platform 14, and each first plate member is placed when the loading platform 14 is placed on the stacking platform 12. The position 24 corresponds to the position of each second plate member 28.

  When the second plate member 28 is placed on the first plate member 24, the top of the rib 24A of the first plate member 24 abuts between the rib 28A and the rib 28A of the second plate member 28, and the second plate The top of the rib 28A of the member 28 abuts between the rib 24A and the rib 24A of the first plate member 24.

  Note that the height of the ribs 28A of the second plate member 28 is made shorter than the height of the ribs 24A of the first plate member 24 only in part or in part so that the ribs 28A do not contact the first plate member 24. Good. By doing so, the contact area of the 1st board member 24 and the 2nd board member 28 can be decreased, and slidability can be improved. In this case, the rib 28 </ b> A has an effect as a guide rib that determines the sliding direction of the second plate member 28.

  Since the tops of the ribs 24A and 28A are abutted against the surfaces of the first plate member 24 and the second plate member 28 facing each other, the plate members not having the ribs 24A and 28A are compared with each other over the entire surface. As a result, the contact area is reduced and the frictional force is reduced.

  That is, the first plate member 24 and the second plate member 28 are easy to slide with respect to each other. Further, since the ribs 24A and 28A are juxtaposed in the longitudinal direction of the first plate member 24 and the second plate member 28, the ribs 24A and 28A act as a guide to each other, and the first plate member 24 and the second plate member 28. Are not shifted from each other in the short direction.

  The loading platform 14 is composed of a plurality of basket-like plastic pallets. Since the load 30 loaded in the container 40 is placed on the top surface of the load platform 14, the load platform 14 has a thickness that can withstand the load of the load 30. The plurality of loads 30 are each sized to be accommodated in the container 40 on the loading platform 14, and the plurality of loads 30 placed on the loading platform 14 are fixed to each other by a binding tool 32.

  A long hole 14A for receiving a forklift claw is formed on the side surface of the loading platform 14. Further, the loading platform 14 is provided with a hook (not shown), and a binding tool 32 is hooked on the hook to fix the luggage 30 on the loading platform 14.

  In addition, as shown in FIG. 1, a step 42 is installed in the vicinity of the loading / unloading device 10. The platform 42 is set to a height at which the side of the container 40 on the rear side of the truck 44 is close to one end of the loading / unloading device 10 when the rear wheel of the truck 44 loaded with the container 40 is placed on the platform 42. ing.

  The container 40 is particularly used for marine transportation. As shown in FIG. 2, a third plate member (plate member) 46 is disposed on the floor surface of the container 40. The third plate member 46 is a plastic plate having the same shape as the first plate member 24 and the second plate member 28 in which a plurality of ribs 46A are arranged in parallel along the longitudinal direction of the floor surface of the container 40. One long third plate member 46 is formed by connecting plastic plates.

  Four third plate members 46 are arranged side by side along the longitudinal direction of the floor surface of the container 40 and are attached to the floor surface of the container 40 with an adhesive or the like. When the loading platform 14 is loaded into the container 40, the position of each second plate member 28 corresponds to the position of each third plate member 46. In addition, between each 3rd board member 46, it is a channel | path when a person works in the container 40. FIG.

  As in the case where the first plate member 24 and the second plate member 28 are brought into contact with each other, the tops of the ribs 24A and 46A are abutted against the surfaces of the second plate member 28 and the third plate member 46 facing each other. , The contact area is reduced, and the frictional force is reduced.

  That is, the second plate member 28 and the third plate member 46 are easy to slide with respect to each other. Further, since the ribs 28A and 46A are juxtaposed in the longitudinal direction of the second plate member 28 and the third plate member 46, the ribs 28A and 46A act as a guide to each other, and the second plate member 28 and the third plate member 46. Are not shifted from each other in the short direction.

  Further, as shown in FIG. 2, a buffer member 48 is provided in the back of the container 40. The buffer member 48 is for stopping the sliding of the load 30 by contacting the loaded load 30 and preventing the load 30 from colliding with the side surface of the container 40.
