  As described above, in the loading device 70, the moving device 76 pulls the loading platform P in a state where the loading platform P on which the luggage B is placed is placed on the plate member 74 on the base portion 72, so It moves in the cargo transport direction and is loaded into the container C (loaded). Specifically, at the time of loading, the pair of winding portions 82 to which the winding force is applied from the driving source 84 winds the linear members 88 constituting both ends of the pulling member 86, respectively. The contact member 90 constituting the central portion of the member 86 pulls the cargo bed P downstream in the cargo transport direction M via the spacer member 64. By this pull-in, the loading platform P moves in the cargo transport direction M and is loaded into the container C together with the cargo B. Here, in the loading device 70, the loading platform P can be moved in the load carrying direction M with a simple structure in which the retracting member 86 is wound up by the winding unit 82.

[Third Embodiment]
Next, a loading device 100 according to a third embodiment of the present invention will be described with reference to FIGS. 15 and 16.

<Loading device 100>
As shown in FIGS. 15 and 16, the loading device 100 is attached to the base portion 22 and the plate member 24, which are the same as those in the first embodiment, and moves the loading platform P in the load carrying direction M. And a moving device 102. The description of the base portion 22 and the plate member 24 is omitted.

(Moving device 102)
As shown in FIGS. 15 and 16, the moving device 102 is configured to push the loading platform P and move it in the load carrying direction M. The moving device 102 includes a moving unit 104 that can move on the base unit 22 in the load carrying direction M, a drive source 106 that applies a moving force to the moving unit 104, and a loading platform P in the load carrying direction via the load B. And a pushing member 108 for pushing.

  The moving unit 104 includes a traveling unit 110 that can travel on the pair of longitudinal members 32 that constitute the frame body 28. The traveling unit 110 includes a pair of rolling wheels 112 that respectively roll on the pair of longitudinal members 32, a pair of restraining wheels 114 that contact the upper inner surfaces of the pair of longitudinal members 32 and suppress the lifting of the rolling wheels 112, and the rolling wheels 112 and a pair of support members 116 that rotatably support the restraining wheel 114, a connection member 118 that connects the pair of support members 116 to each other, and a mounting plate portion 120 provided at the center of the connection member 118. ing. Note that a belt-shaped resin material is wound around the outer periphery of the roller wheel 112 in order to improve the frictional force generated between the upper surface of the vertical member 32. As this resin material, for example, urethane or rubber may be used.

  The drive source 106 is an electric motor mounted on the mounting plate portion 120. A moving mechanism (not shown) converts the driving force (rotational force) of the electric motor into a propulsive force of the traveling unit 110 so that the traveling unit 110 travels on the vertical member 32. The moving mechanism is not particularly limited as long as the driving force of the driving source 106 can be converted into the driving force of the traveling unit 110. For example, the racks are arranged between the panel members 30 along the load carrying direction M, and the rotational force of the electric motor that is the drive source 106 is transmitted to the racks via a plurality of gears to be converted into the propulsive force of the traveling unit 110. The traveling unit 110 may be moved. In addition, for example, a pair of pulleys (or gears) are attached between the panel members 30 on the upstream side and the downstream side in the cargo transport direction M, and the belt (or chain) is circulated around these pulleys (or gears). Accordingly, the traveling unit 110 may be configured to travel in the cargo transport direction M. Still further, for example, a linear member (wire, rope, etc.) is passed between the panel members 30 along the load carrying direction M, and the leading end of this linear member is attached to the cross member 34 downstream in the load carrying direction. The rotational force of the electric motor 106 may be transmitted as a winding force to a winding unit (not shown) via a plurality of gears, and the traveling unit 110 may travel in the cargo transport direction M by winding a linear member. .

  The pushing members 108 are respectively attached to the distal end portions of the projecting portions 122 projecting upward from the support members 116 of the pair of traveling units 110 at both ends in the longitudinal direction. The protruding portion 122 protrudes from between the rolling wheel 112 and the restraining wheel 114 of the support member 116. With the above configuration, the pushing member 108 moves as the travel unit 110 moves, and pushes the loading platform P via the luggage B.

  Next, the effect of the loading device 100 of this embodiment is demonstrated. In addition, about the effect obtained by the structure similar to 1st Embodiment, since the same effect is obtained also in the loading apparatus 100, the description is abbreviate | omitted suitably.

  In the loading device 100, as shown in FIGS. 15 and 16, when the pushing unit 108 comes into contact with the load B due to the movement of the traveling unit 110 and a moving force is applied to the load B, a reaction force against the moving force is generated. It acts in the direction in which the protrusion 122 is tilted. When the reaction force acts on the support member 116, the restraining wheel 114 is pressed against the upper inner surface of the longitudinal member 32, and the rolling wheel 112 is pressed against the upper surface of the longitudinal member 32. As a result, the traveling unit 110 can be moved in the load carrying direction M by efficiently converting the driving force from the drive source 106 into the propulsive force of the traveling unit 110 without lifting the traveling unit 110.

  In the loading device 100 of the present embodiment, the drive source 106 is attached to the attachment plate portion 120 of the traveling unit 110, but the present invention is not limited to this configuration. For example, the driving unit 106 may not be attached to the mounting plate 120, and the traveling unit 50 of the first embodiment may be connected to the traveling unit 110. In this case, the traveling unit 110 is moved by the moving force of the traveling unit 50. Further, for example, the drive source 106 is not attached to the attachment plate portion 120, and the linear member 88 of the second embodiment is connected to the support member 116 or the protruding portion 122 of the traveling unit 110, and the drive force from the drive source 84 makes a line. The traveling unit 110 may be pulled and moved in the load carrying direction M by winding the shaped member 88 by the winding unit 82.

In the loading device 20 of the first embodiment, the base portion 22 is configured by the frame body 28 and the plurality of panel members 30 fitted inside the frame body 28, but the present invention is not limited to this configuration. . For example, instead of the plurality of panel members 30, a plate material (for example, a steel plate) may be attached to the upper surface of the frame body 28, and the plate member 24 may be disposed on the plate material. Further, the frame body 28 and the plate material may be integrally formed and installed on the floor surface F. Further, a reinforcing member may be added to the frame body 28. Furthermore, it is good also as a structure which makes a part of base part 22 project toward the site surface G from the floor surface F. FIG.
The various configurations described above may be applied to the loading device 100 of the third embodiment.
Moreover, in the loading apparatus 70 of 2nd Embodiment, although the base part 72 is comprised with the supporting member 78 and the several panel member 30, this invention is not limited to this structure. For example, a plate member (for example, a steel plate) or the like may be attached to the upper surface of a long frame-shaped member that is integrally formed instead of the plurality of panel members 30, and the plate member 24 may be disposed on the plate member. Further, the support member 78 and the frame member may be integrally formed and installed on the floor surface F. Furthermore, it is good also as a structure which makes a part of base part 72 project toward the site surface G from the floor surface F. FIG.

  In the first embodiment, the loading device is installed on the floor F of the warehouse, but the present invention is not limited to this configuration. It may be installed on the floor of a stilt factory or on the floor of a stilt truck yard.
