Description of the Related Art As a device for loading required cargo on the carrier of a freight vehicle, a crane of a lifting type is provided above the carrier, or a horizontal beam is erected in the front-rear direction and a chain block can be freely moved. The ones provided in the are known. On the other hand, in recent years, in the transportation situation, a box-type freight vehicle in which a rear cargo bed is surrounded by a top plate and side walls has come into wide use. Freight vehicles of this type often carry cargo in and out only at the rear opening. Therefore, the conventional hoist type crane cannot be applied because it has a ceiling.

Further, it is necessary to store the loads to be loaded on the loading platform from the front, that is, from the deepest position as seen from the opening to the opening side. Therefore, when loading luggage, a tailgate lift that reaches the ground from the trailing edge of the loading platform at the rear opening is used, and a belt conveyor, a pallet loader, or the like is used to move the cargo on the loading platform.

[0004]

The tailgate lift, the belt conveyor, and the pallet loader have various problems as described below. That is, when the tailgate lift is used, it is necessary to load the load on the lift manually or the like, and a separate moving device is required for moving the load on the loading platform. When the belt conveyor is installed on the luggage carrier, horizontal movement of the luggage is facilitated, but vertical movement on the luggage carrier is not so much improved, and the load capacity of the luggage is reduced by the installation space of the belt conveyor. Also in the case of a pallet loader,
It has the same problem as the belt conveyor.

The present invention has been made in view of the above problems, and an object thereof is to provide a cargo handling apparatus capable of efficiently loading and unloading cargo.

[0006]

Means and Actions for Solving the Problems The above object of the present invention is to provide a loading and unloading apparatus for loading and unloading cargo, wherein the trolley is horizontally movable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. 1 is a perspective view of a cargo handling device and a freight vehicle using the same, FIG. 2 is a side view showing the structure of the cargo handling device, FIG. 3 is a plan view, FIG. 4 is another side view, and FIG. FIG. 6 is a schematic explanatory view showing the handing over, and FIG. 6 is a schematic explanatory view showing the structures of the suspenders and the trolley cart.

First, the overall structure of the cargo handling device 1 will be described.
The structure of the cargo handling device 1 is roughly divided into a trolley 2 for reciprocating the entire device 1 in the horizontal direction, for example, in the back and front directions on the cargo carrier b of the freight vehicle a, and is rotatably provided on the trolley 2. The support pillar 3, the trolley carriage supporting member 4 that rotates integrally with the support pillar 3, the trolley carriage 5 that moves in the longitudinal direction of the trolley carriage supporting member 4, and the trolley carriage 5 that is movable together with the trolley carriage 5 and will be described later. It is configured by a luggage suspending device 7 configured to be movable in the vertical direction by winding and unwinding the rope 6 of the book. The luggage hanging device 7 will be simply referred to as a hanging device hereinafter.

At the lower part of the carriage 2, there are provided a drive roller 12 for causing the carriage 2 to travel along a guide rail 11 provided on the loading platform b, and a roller 13 for causing the carriage 2 to travel stably. Further, a traveling motor 14 for traveling the truck 2 is provided above the truck 2. The traveling motor 1
The drive roller 12 is rotationally driven by the drive roller 4. The column 3 is provided with a lifting motor 15 for vertically moving, that is, lifting and lowering the lifting tool 7 by winding and unwinding the rope 6. The trolley cart 5 is configured to support the hanging device 7 so as to be able to move up and down, and to move in the longitudinal direction along a pair of rails 16 provided on the trolley cart support member 4.

Next, the suspension of the rope 6 and the suspension 7 will be described. One end of the rope 6 is wound around the drum 20 as schematically shown in FIG. 5, and the rope 6 is sequentially wound around the guide rollers 21 to 32, and then the other end is fixed to the end portion of the trolley cart supporting member 4. . Since the drum 20 is configured so as to be bidirectionally urged by the lifting motor 15, the rope 6 is wound and unwound by rotating the lifting motor 15. Of the guide rollers 21 to 32, 24 and 2
Reference numerals 5, 30, and 31 are rotatably attached to the hanger 7, and reference numerals 23, 26, 29, and 32 are rotatably attached to a trolley cart 5 described later. In addition, the guide roller 21 is provided at a predetermined position of the supporting column 3 with the guide roller 22,
27 and 28 are rotatably attached at a predetermined position of the trolley cart supporting member 4.

Therefore, when winding the suspended rope 6, the winding allowance, in other words, the length that can be wound corresponds to the distance between the trolley cart 5 and the hanger 7.
When the rope 6 is wound up, the hanger 7 rises, that is, approaches the trolley cart 5. Further, when the rope 6 is unwound, the distance between the trolley truck 5 and the suspending tool 7, in other words, the distance becomes longer, and the suspending tool 7 descends, that is, farther from the trolley truck 5.

Next, the structure and operation of the suspension 7 and the trolley truck 5 will be described. First, the structure of the trolley cart 5 will be described. The trolley truck 5 includes a joint plate 51 and a shaft 52 attached to both ends of the trolley truck 5 with a predetermined distance A,
53, a pair of rollers 23 and 32 provided for hanging the rope 6 on one shaft 52, and a pair of traveling rollers 5.
4, 55, and a pair of rollers 26 and 29 provided for hanging the rope 6 on the other shaft 53 and the traveling roller 5.
It is composed of 6, 57.

On the other hand, the suspender 7 is provided with a pair of roller fixing plates 62, 63 on the upper part of the substrate 61, and one roller fixing plate 6 is provided.
Rollers 24 and 25 for wrapping the rope 6 at a predetermined interval B are rotatably attached to 2, and rollers 30, 31 for wrapping the rope 6 at a predetermined interval B on the other roller fixing plate 63 are rotated. It is freely attached, and a luggage suspension is provided below the substrate 61. It should be noted that the hanging of the luggage is not limited to the hook, and a suction tool or the like can be applied.

Then, one rope 6 is attached to the trolley truck 5.

It is handed over to 31. Furthermore, the trolley truck 5 is wound around the rollers 32. Therefore, although the number of ropes 6 is one, as shown in FIG. 5 in particular, the suspending tool 7 is as if suspended by four ropes. Therefore, the load of the hanger 7 is
The load between the rollers 3 and 24, the rope between the rollers 26 and 25, the rope between the rollers 29 and 30 and the rope between the rollers 32 and 31 is distributed. Reduce to.

By the way, the distance A between the rollers of the trolley truck 5 and the distance B between the rollers of the suspension 7 are:
The relationship is A> B. This interval setting allows the hoisting device 7 to be lifted when the hoisting device 7 is lifted to the maximum.
It is for storing so to speak at the bottom of. According to this structure, the lifting tool 7 can be lifted up to the set height of the trolley cart supporting member 4, and the loads can be lifted up to the ceiling of the loading platform b and loaded. Further, even if the load is tall, it is easy to carry out the loading work.

Next, the loading operation will be described. When loading, the entire cargo handling apparatus 1 is moved to the rear end of the cargo bed b as shown in FIG. Next, the trolley cart supporting member 4 is rotated to the outside of the loading platform b, and the elevating motor 15 is further driven to feed the rope 6. As a result, the suspending tool 7 descends due to the above action, and the load can be suspended. At this time, the drive roller 12 provided at the bottom of the carriage 2
However, since it is pressed by the rail 11, the cargo handling device 1 does not fall outside the cargo bed b.

After the hanging of the load is completed, the lifting motor 15 is driven to wind the rope 6. As a result, the lifting device 7 as a whole rises due to the above action. Then, for example, after hoisting to a height at which the luggage can be loaded on the cargo bed b, the traveling motor 14 is driven to move the device 1 in a state in which the luggage is hung to the back of the cargo bed b. After the loads are carried to the stacking position, the lifting motor 15 is driven so that the rope 6 is unwound again. Then, by separating the luggage from the hanging device 7, the loading operation of the luggage is completed. It should be noted that loading and unloading of cargo is performed promptly by a work opposite to the above-mentioned loading work.

As described above, although the cargo handling device 1 according to the present invention uses one rope 6,
Since the hanging tool 7 is hung by a plurality of ropes, the hanging tool 7 can be stabilized. In addition, lifting and lowering of the hanging device 7, in other words, lifting and lowering of luggage can be performed by winding and unwinding one rope 6.

Further, since the trolley cart supporting member 4 for supporting the hanging device 7 is constructed so as to be rotatable in the horizontal direction,
When carrying out loading and unloading, it is possible to carry out the work while the suspending tool 7 is being pushed out of the loading platform b integrally with the trolley cart supporting member 4, and the load is lifted up to the height of the loading platform b by hand and held. There is no need to lower it. In other words,
It is possible to hang the load outside the loading platform b, carry it as it is, carry it to the loading position, and unload it. Therefore, even heavy and large loads can be easily loaded and unloaded, workability can be greatly improved, and manpower can be saved.

Further, the hanging device 7 is the trolley cart supporting member 4
Since it is housed inside, it is not necessary to leave a space for the hanger 7 in the upper space of the loading platform b, and the limited space of the loading platform b can be effectively used.

Next, a second embodiment of the present invention will be described with reference to FIGS. 7. FIG. 7 is a perspective view showing the overall structure of the cargo handling apparatus, and FIG. 8 is a side view for explaining loading and unloading. The difference between this embodiment and the first embodiment is that
The support member is a cantilevered support, which is supported by both ends, and is configured to be rotated in the vertical direction about the loading platform instead of being horizontally rotated. Therefore, the same reference numerals are given to the portions having the same operations as those in the first embodiment, and the description thereof will be omitted.

Therefore, as shown by the solid line in FIG. 8, the device 101 does not fall down even if the suspending tool 7 that suspends the load is rotated from the inside to the outside, that is, as shown by the phantom line, outside the loading platform b. The carriages 102a and 102b are run and stopped by driving and stopping the travel motor 14, and the carriage traveling member 105 is biased and stopped by driving and stopping the rotation motor 106. .

It should be noted here that the angles θa, θA, θb, and θB of the respective parts shown in the figure are the same as those of the rotating support column (10).
3 and 104) regardless of the rotational position, θa + θb = θA
+ ΘB = const. Therefore, the position of the hanger 7 with respect to the carriage traveling member 105, in other words, the height h does not change unless the lifting motor 15 is driven.
Then, the load suspended as shown by the solid line in FIG. 8 is loaded outside the loading platform b at the same height, and the lifting motor 1 is moved from the position where the rotation columns 103 and 104 are stopped to rotate.
5 is driven and the rope 6 is paid out to unload the rope.

On the other hand, when loading, the suspending tool 7 is taken out of the loading platform b as shown by the phantom line, and the suspending tool 7 is lowered at that position to suspend the load, and the columns 103 and 104 are moved in the y direction. Rotate to. At this time, if the loading position is behind the loading platform b, the carts 102a and 102b are run. Further, the traveling rollers 111a and 113a are connected to the stoppers 116a and 11a.
It may be locked to 6b. Further, if the loading position is within the range reached by the rotation of the rotation columns 103 and 104, the carriage 102
It becomes unnecessary to run a and 102b.

When the traveling rollers 111a and 113a are locked to the stoppers 116a and 116b during the loading as described above, if the loading position is low, the height h of the hanger 7 is as described above. Since it does not change, it is not necessary to wind up the hanging device 7 after hanging the luggage,
The rotating columns 103 and 104 can be rotated as they are to perform unloading. That is, hoisting and lowering of the hanging device 7 are not necessary according to the loading position, and the efficiency of loading work can be improved.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above, and various modifications can be made. For example, also in the second embodiment, the same rail as in the first embodiment may be provided, or the stopper 116 may be extended. The trolley cart may be configured to reciprocate by a motor. The length of the support column 3 and the rotation support columns 103 and 104 may be adjusted.
