Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for loading and unloading cargo onto a pan-type vehicle or a flat body vehicle (hereinafter referred to as a vehicle), and an apparatus for carrying out this method.

(Prior art) Conventionally, a vehicle is parked sideways on a platform in a backward position,
Loading and unloading cargo through the rear opening was all done manually.

In other words, when it comes to loading cargo.

As shown in FIG. 7, the workers carried the luggage scattered on the platform one by one, and loaded the luggage into the loading platform C one by one from the front. Alternatively, although not shown, a portable conveyor was used for loading work. Most of these tasks involved loading by workers, and improvements in efficiency were desired.

In particular, there has been a desire to shorten the loading time of baggage in pan-shaped vehicles intended for small-lot transportation.

(Problems to be Solved by the Invention) In view of the prior art, a method for loading and unloading cargo loaded on a platform can be efficiently loaded and unloaded using simple tools that do not require human labor, and an apparatus for carrying out this method. The purpose is to provide

(Means for solving the problem) A loading winch is provided on the vehicle side, a pull-out winch is provided on the platform side, a sheet plate made of resin is placed between both winches, the cargo is placed on the sheet plate, and the load winch is installed on the vehicle side. By operating the loading winch to pull in the entire sheet board for loading, and conversely by operating the pull-out winch on the platform side to pull down the cargo along with the sheet board onto the platform, loading and unloading of cargo is efficient. I made it possible.

A device for carrying out the above method is a loading winch under the floor of the front part of a vehicle equipped with a chucking device at the end of the rope, a pull-out winch on a platform also equipped with a chucking device at the end of the rope, and a loading winch on the platform with a chucking device at the end of the rope, and a loading winch on the platform with a chucking device at the end of the rope. It consists of a sheet plate that can be connected.

In addition, with the above device, a loading winch is installed on the end wall of the platform, and a rope on the loading winch side and a detachable rope are installed on the vehicle side, and the ropes are connected under the floor of the vehicle when loading cargo. did.

Furthermore, the sheet plate used in the above device is a flat plate, a flat plate with holes, or has a removable wall, making it suitable for conveying irregularly shaped cargo.

(Example) The cargo handling method of the present invention will be explained using a pan-type vehicle based on FIGS. 1 and 2. Reference numeral 61 is a pan-type vehicle, which is currently approaching the platform 2 in a backward manner. A sheet plate 3 made of, for example, synthetic resin is placed on the platform 2, and many pieces of luggage A are piled up on this sheet plate 3.

4 is a drawer winch provided on the platform 2, and 5 is a loading winch provided at the front lower part of the pan-type vehicle. A chuck device 7 is attached to the tip of the rope 6 of the draw-out winch 4, and can grip the edge portion 3a of the sheet plate 3 and pull it out.

There is also a chuck device 9 at the end of the rope 8 of the loading winch 5.
is attached, and by grasping the front edge 3b of the seat plate 3, the cargo can be loaded together with the seat plate 3 into the pan-type vehicle.

Note that the cargo A placed neatly on the sheet board 3 on the platform 2 is moved into the loading platform by winding up the winch 5;
Since the movement of the sheet plate 3 involves large frictional resistance, smooth movement can be achieved by attaching a roller conveyor to the lower surface of the sheet plate 3 or attaching a resin plate or the like with a small coefficient of friction. Although this embodiment has been described with respect to a pan-type vehicle, it is of course applicable to a flat-body vehicle as well.

(Operation) With the above configuration, the procedure for retracting the seat plate on which the cargo A is placed on the cargo platform is as follows.

a) Work on the platform ■ A roller conveyor (not shown) is installed on the platform 2.

■Place sheet board 3 on the conveyor.

■Place the luggage A in a line on the seat board 3.

■Ready for loading (wait for vehicle to arrive).

b) ■Attach the pan-shaped vehicle vertically to platform 2 in a backward position. In this case, it should be aligned with the position of the sheet plate 3.

■Open the rear door of the pan-shaped vehicle.

■Pull out the chuck device 9 of the winch on the vehicle side to the seat plate 3.

■ Grip the edge of the sheet plate 3 with the chuck device 9.

(2) Drive the loading winch 5 to pull the sheet plate 3 into the cargo shed, and stop the loading winch 5 at a predetermined position.

■Close the door.

■Departure.

(Second example) This will be explained based on FIG. In this example.

A loading winch is not installed on the vehicle side, and the loading winch for loading the vehicle is also installed on the platform 2 side.

And a rope 8 equipped with a chuck device 9 at the tip on the loading platform side
is stretched across a pulley 10. The end of the rope 8 opposite the chuck device 9 is finished with a clip 11. On the other hand, the end of the rope 12 of the platform side loading winch 5 installed on the end wall of the platform 2 is also finished with a clip 13, and when pulling the cargo A into the loading platform, the clip 11 on the vehicle side and the platform side winch are finished. It is connected to the clip 13 via a shackle (not shown). Since the rope 8 of the vehicle side chuck device 9 slackens when the sheet plate 3 is in the loading platform, it is wound up under the loading platform and stored in an appropriate space under the floor.

When a pan-type vehicle loaded with luggage is vertically mounted on the platform 2 and unloads the luggage A, the pull-out winch 4 on the ground side 7 is used. First, the door is opened, and the chuck device 7 attached to the end of the rope 6 of the pull-out winch 4 on the ground side is pulled close to the loading platform of the bread-type vehicle. The edge of the sheet plate 3 is gripped by a chuck device 7, and the drawer winch 4 is driven to pull out the cargo. In this case, it is advisable to lay a resin sheet or a roller conveyor in advance on the platform side on the extension of the loading platform opening.Next, an example of the sheet plate 3 will be explained below. It is a sheet board made of When loading cargo, leave some space for the chuck to grip at the front and back. This sheet plate is suitable for relatively modular luggage.

Note that the size (width x length) of the seat plate is formed to a fixed size that is slightly smaller than the inside size of the vehicle's cargo bed.

FIG. 4(b) shows a so-called box-type pallet 3B in which walls 14 are removably provided on the left and right front edges of the sheet plate 3A. When loading cargo, the wall 14 is removed and placed, that is, it is loaded in the same manner as the sheet board 3A.
Finally, erect the wall 14. Therefore, grooves 15 into which the lower ends of the walls 14 fit are provided on three sides of the sheet plate 3A.

Further, since the upper ends of the wall bodies 14 become unstable during movement of the sheet plate 3A, it is preferable to connect the left and right walls 14 with a steady rest rod 16.

Further, corner fittings 17 (FIG. 5) formed at right angles are inserted into the corners of the front wall and left and right side walls to stabilize the wall. The box-type pallet 3B prevents the load from collapsing when loading and unloading the load onto the bread-type vehicle or while the vehicle is running, and is also suitable for transporting relatively irregular-shaped loads.

FIG. 4(c) shows an example of a sheet plate used in a frozen bread type vehicle. A plurality of holes 18 are bored in the sheet plate 3C to the extent that the strength of the sheet plate 3C is not impaired. Cold air from under the floor is circulated through these holes. This hole 18 can also be bored in the floor surface of the box-type pallet 3B shown in FIG. 4(b).

(Effects) According to the method and device for loading and unloading cargo according to the present invention, 1) Since the cargo can be loaded or unloaded using mechanical force on the sheet plate on the platform side, loading and unloading is possible.
The loading and unloading workability is very good, and it greatly contributes to reducing labor and cargo handling time.

2) The vehicle can be loaded onto the sheet board before it is vertically mounted, and therefore the loading work can be done in a short time after the vehicle arrives, improving the vehicle operating turnover rate.
