Abstract

PURPOSE:To enable luggage of different specifications to be conveyed by only modifying the specifications of a truck, by a method wherein a truck and an unmannedly guided traveling body are detachably fitted to each other and are moved as one body in the traveling diretion, in the titled truck for conveying luggage in an unmanned manner. CONSTITUTION:The truck 2 in which legs 2b having freely rotatable casters 2c at their lower ends are provided below the luggage carrier 2a is detachably held on an upper part of the unmannedly guided traveling body 1 incorporating various control mechanisms required for unmanned traveling so that it can be moved in the vertical direction. The weight of the luggage conveyed is entirely supported by the truck 2, and is prevented from acting on the traveling body 1. Accordingly, the system can be adapted for conveying various luggage of different specifications by only modifying the specifications of the truck 2 without modifying the specifications of the traveling body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an unmanned guided trolley that transports cargo unmanned.

2. Description of the Related Art Unmanned guided carts are known that load cargo onto an upper loading platform and travel along a predetermined track or guide line.

Conventionally, in this type of unmanned guided trolley, the loading platform and the unmanned guided trolley body have an integrated U] structure, so it is possible to When changing the specifications of the loading platform, the main body of the unmanned guided trolley itself must be significantly redesigned and remanufactured each time.
There were problems such as high manufacturing costs.

Recently, unmanned guided carts equipped with an automatic transfer device on the loading platform that automatically transfers cargo between the loading platform and a transport mechanism such as a conveyor installed at a station have become widespread. If the transfer device is driven by a drive source housed within the frame of the main body of the unmanned guided trolley, the unmanned guided trolley may be modified due to a change in cargo specifications as described above, or the unmanned guided trolley may be damaged in addition to the loading platform. This is necessary for many parts of the guide truck main body and automatic transfer device, making modification work considerably complicated.

This invention was made in consideration of the above-mentioned circumstances, and includes an unmanned guided running body disposed below the bogie, and a structure in which the bogie and the unmanned guided running body are removable and move integrally in the running direction. The purpose of the present invention is to provide an unmanned guided trolley which can be adapted to transport various types of cargo with different specifications by simply changing the specifications of the trolley, and which reduces manufacturing costs by connecting the trolleys in such a way that .

Hereinafter, an example of this theory 1i1 will be explained according to Figure ■i.
Figures 1 and 2 show a first embodiment of the present invention, and the symbol l in the figures indicates an unmanned guided vehicle.

This unmanned guided vehicle 1 has a bumper la on the qli, one traveling wheel 1b on each of the front, rear, left, and right sides of the lower part, and has an unmanned steering control mechanism, a travel control mechanism, and a destination setting professional vehicle 2 in its internal heat. A holding stand that removably connects 1. A material 8 is provided.

The truck 2 has legs 2b provided at the lower t corners of a box-shaped loading platform 2a, and a swing width 2JC provided at the lower end of the legs 2b. The legs 2b and the freely rotating wheels 2C are provided with a strong traction force capable of withstanding the entire weight of the cargo placed on the loading platform 2a.
bσ] The length is 78. is higher than the height H2 of the unmanned guided vehicle 1, and the distance W1 between the legs 2b facing each other in the width direction (direction perpendicular to the traveling direction of the unmanned guided vehicle 1) is set to be higher than the height H2 of the unmanned guided vehicle 1. It is designed to be wider than the traveling body 1 (1) li, i w.

The nijiki holding material 8 is attached to the leg 2b of the cart 2 at the tip 4a.
A guide material 4 having a notch ff1i4b that vertically penetrates the guide material 4 and whose base end 4C side is fixed to the unmanned guided vehicle 1 via a tightening member 5 such as a bolt, and the notch gI)
A fixing member 7 is fixed to both ends of the leg 2b via a tightening bolt 6 such as a bolt, and fixes the leg 2b horizontally and slidably in the vertical direction.
The bogie 2 is not restrained in the vertical direction relative to the unmanned guided vehicle 1, but is held so that the freely rotating wheels 2C attached to the lower ends of the legs 2b are always in contact with the ground.

An automatic transfer device 8 is provided on the loading platform 2a of the truck 2.

This automatic transfer device 8 includes a loading machine 8a such as a roller conveyor installed above the loading platform 2a, and a loading machine 8a such as a roller conveyor installed above the loading platform 2a.
It is equipped with a transfer control box 8b which has a built-in control device for controlling a and which is installed in the back heat of the ltj recording platform 2a, and h(
(The drive device for the loading machine Ba is housed in the loading platform 2a.

In addition, if the structure of the holding member 8 is 0 years old, and the truck 2 is not restrained in the vertical direction and is held in an unmanned guided vehicle so that the freely rotating wheels 2C of the legs 2b of the truck 2 are always in contact with the ground,
n] Not limited to those with the structure described in 1, and holding T
The location is not limited to the leg 2b of the truck 2.

Moreover, FIG. 3 and FIG.
In Fig. 3, a belt conveyor is adopted as the loading machine 8a, and the 4th h ['LJ'') lid (elevator)?i:
It shows what has been adopted.

Moreover, FIG. S shows another embodiment of the unmanned guided vehicle l, in which various control mechanisms are provided in the head lO protruding upward from the front end of the chassis 0, and a bogie 2 is fixed on the chassis 9. A holding member 8 is provided for holding the handle.

In the unmanned guided trolley of the present invention configured as described above, the trolley 2, which is not provided with the legs 2b having the freely rotating wheels 2C at the lower end below the loading platform 2a, is equipped with various control mechanisms necessary for unmanned running. It is held removably and movably in the vertical direction on the ground 〇 of the unmanned guided traveling body l having the following structure, and all the load due to the cargo to be transported is supported by the trolley 2 so that it is not applied to the unmanned guided traveling body l. Therefore, by simply changing the specifications of the trolley 2 without changing the specifications of the unmanned guided vehicle 1, it becomes possible to adapt the system to the transportation of various types of cargo with different specifications. Therefore, it takes a long time to design, manufacture, etc. due to changes in baggage specifications.
It is suitable for reducing manufacturing costs by reducing the amount of work involved, and
Effects such as the ability to easily expand the applicable uses of conveyed objects are produced.

These effects are particularly noticeable when the loading platform 2a is provided with an automatic transfer device @8 and has a complicated structure.

In addition, when inspecting the unmanned guided vehicle l, the tightening members 5 and 6 of the holding member 8 are removed and the bogie 2 is moved to the unmanned guided vehicle l.
Since the automatic transfer device 8 and the loading platform 2a can be separated from each other during inspection work, there is no need for the automatic transfer device 8 or the loading platform 2a to get in the way, resulting in various effects such as improved workability during maintenance.
