DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor-conveying apparatus having a floor-conveyor structure used as a bed for vehicles such as large trucks and trailers and a bed for warehouses.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. 3-53210 discloses a floor surface transfer device for automatically transferring a load loaded on a long rear loading platform such as a large truck in the front-rear direction.
This floor surface transfer device has a plurality of floor members 1 laid in parallel on the bottom of a box-shaped carrier 3 of a large truck as shown in FIG. 5, for example. Each floor member 1 is a straight plate made of, for example, aluminum which is long in the front and rear direction. A plurality of the same length members are installed in the width direction in parallel with each other at the bottom of the loading platform 3. Thus, a substantially horizontal floor surface 2 is formed.
Each floor member 1 repeats a reciprocating motion with a constant stroke back and forth while maintaining a substantially horizontal posture by a hydraulic drive system (not shown), and automatically conveys the load loaded on the floor surface 2 in one of the front and rear directions.

[0003] A method of transporting a load using the floor member 1 will be described with reference to schematic plan views of the floor surface 2 in Figs. FIG. 6 shows six floor members 1 in which the number is reduced for simplicity, and the six floor members 1 are counted from one end in the parallel direction.
The first and fourth two members constitute the first group of floor members 1a, and the second and fifth two members constitute the second group of floor members 1b.
And the third and sixth members constitute the floor member 1c of the third group. Hereinafter, only in the case of grouping, the floor members 1a, 1b, and 1c are displayed and distinguished.

Assuming that the leftward direction in FIGS. 6 and 7 is forward X and the rightward direction is backward Y, FIG. 6 shows that all floor members 1 are in the forward position where they have moved forward X, and are formed by the floor members 1. When 10 is loaded on the back of the floor surface 2, each floor member 1 moves back and forth in the manner shown in FIGS.
Is transported intermittently to the back side of the front X of the carrier 3 by a constant stroke. Specifically, first, as shown in FIG. 7A, the floor member 1a of the first group moves backward Y by a fixed stroke. The frictional force between the floor member 1a of the first group moving rearward and the load 10 is larger than the total frictional force of the load members 10 and the floor members 1b and 1c of the second and third groups at rest. Therefore, the cargo 10 does not move while remaining stationary. Next, as shown in FIG. 7 (B), the floor members 1b of the second group are moved backward Y by a fixed stroke, and subsequently, as shown in FIG. 7 (C).
c moves backward Y by a fixed stroke. Even when these groups move backward, the cargo 10 remains stationary. Then, as shown in FIG.
When all the floor members 1 are simultaneously moved forward X by a constant stroke, the load 10 on each floor member 1 is intermittently fed forward X by a constant stroke.

[0007] By repeating the operations of FIGS. 7A to 7D several times, the load 10 is intermittently fed on the floor 2 to the back of the front X by a constant stroke, and finally, FIG. The load 10 is transported to the foremost position on the floor 2 as shown in FIG. Each floor member 1 in FIG. 7 (E) is at a retracted position lowered to the rear Y, and in this state, the floor members 1 of the first to third groups are set.
When a to 1c are advanced in order by a constant stroke, the load 10
Is stationary, and when the floor members 1a to 1c of all the groups that have moved forward and retreated at the same time by a fixed stroke, the load 10 moves backward Y by a fixed stroke. By repeating this backward movement, the deepest cargo 10 on the floor 2 is intermittently fed backward Y by a constant stroke, and finally discharged from the entrance 5 at the rear end of the floor 2.

[0006] In the above-described floor transfer device, since the entire floor surface operates, a large space for the loading platform can be taken and a large amount of load can be transferred at a time. In addition, cargo is not limited to boxes, pallets, and bags, as well as undefined loose objects such as earth and sand, gravel, and wood chips.
Powders are also possible.

[0007]

However, in the above-mentioned floor transporting apparatus, the floor member 1 reciprocates with a constant stroke in the front-rear direction of the loading platform 3, so that the floor member 1 is retracted backward Y of the loading platform 3. As shown in FIG. 7, a gap H between the front end of the floor member 1 and the front wall of the bed 3 is slightly larger than the stroke of the floor member 1 by a certain amount.

[0008] As described above, the above-mentioned floor transport device is inevitably provided between the front end of the floor member 1 and the front wall of the carrier 3.
The gap H is approximately the same as that of the stroke, but the gap H is slightly larger. Therefore, when loading irregularly shaped loose or granular materials such as earth and sand, gravel, and wood chips, the gap from the gap H to the operating portion of the floor member 1 Bubbles or powdery particles may enter.

Therefore, as shown in FIG. 8, a metal shield plate 6 which covers the gap H between the tip of the floor member 1 and the front wall of the carrier 3 is provided at the lower portion in front of the carrier 3 in an inclined manner. The gap H is covered by the shield plate 6 to prevent loose and powdery substances from entering the operating portion of the floor member 1. The shield plate 6 has its upper end and both sides fixedly attached to the front and side walls of the loading platform 3 and is integrally attached thereto, and has a bent lower end portion formed of a plurality of floor members 1 via a resin sliding contact plate 7. By being in close contact with the floor 2, the airtightness with the floor surface 2 is maintained, and the floor member 1 can smoothly reciprocate with a constant stroke.

However, if the shield plate 6 is provided in the front lower portion of the loading platform 3 in such a manner as to be inclined, the load flows on the shield plate 6 when the load is irregular bulk or powdery material. There is no particular problem because the cargo can be loaded on the forefront of the cargo bed 3, but if the cargo is a regular box, pallet, or bag with no risk of foreign matter invading the operating part of the floor member 1, a shield is used. Since the load does not flow on the plate 6, a dead space is formed at the forefront of the loading platform 3, and the loading efficiency is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a floor transporting apparatus capable of efficiently loading a box, a pallet, or a bag having a fixed shape. Aim.

[0012]

According to the present invention, a plurality of floor members extending in a substantially horizontal front-rear direction and capable of reciprocating at a constant stroke in the front-rear direction are provided on the bottom of a box-shaped carrier. The floor is formed on the upper surface of each floor member by arranging in parallel with each other, and the load placed on this floor member is intermittently fed on the floor surface by controlling the direction and order of the forward and backward movement of each floor member. In the floor transfer device according to the above, a shield plate which is provided in an inclined shape so as to cover the gap between the tip of the floor member and the front wall of the loader is provided at the lower front part of the loader, if necessary. The above-mentioned object is achieved by approaching in an upright manner while maintaining a distance close to the wall.
