Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a logistics device that stocks and ships cargo and loadable cases directly onto a floor seat installed on the floor or in the air without using shelves or roller conveyors.

BACKGROUND OF THE INVENTION In recent years, logistics equipment that supplies parts to factory assembly lines and the like has been required to be able to quickly respond to changes in the factory layout.

Conventionally, this type of physical distribution apparatus is shown in FIGS. 2 and 3. The configuration will be explained below.

As shown in the figure, a three-dimensional warehouse 10 has shelves 11 installed in multiple stages, and loads 14 are transferred to and from other distribution means 13 using a horizontally and vertically movable transfer device 12.

Further, as other conventional examples, there are those shown in FIG. 4 and FIG. ε. The configuration will be explained below.

As shown in the figure, a track 15 is disposed in the air within a multi-level warehouse 10, and is used to carry an aerial mobile automatic guided vehicle 17 equipped with a cargo lifting device 16, stock it on shelves, and ship it. Ta.

The problem that this invention aims to solve is that conventional logistics equipment has a problem with the weight of the cargo handled. Due to the heavy weight of equipment such as the A11, it was necessary to construct it on the first floor of a building or install it on multiple floors with a sturdy foundation and floor construction. For this reason, when adding equipment to the current factory equipment, a dedicated building is required, or an excessive investment is required, but when a factory requires quick response such as parts supply, it is possible to avoid long transfer distances. There were problems in that it was difficult to deal with, and it was difficult to switch production.

In addition, in order to respond to needs that require immediate response, such as when supplying parts to factory assembly equipment, the conveyor itself can be used as a warehouse, even if it is placed above the assembly equipment with a logistics supply device or in a shelf-type warehouse. However, there were some openings that could not be adopted due to the construction schedule and cost due to the large weight and volume of the equipment.

The present invention is intended to solve the above-mentioned problems, and aims to provide a logistics supply system that can respond immediately without unreasonably reducing equipment costs and schedules.

Means for Solving the Problems In order to achieve the above object, the present invention provides an aerial mobile automatic guided vehicle having a plurality of baggage inventory positions separated and set on the floor, a luggage lifting function, and the aerial mobile automatic guided vehicle. The automatic guided vehicle includes a track means and a control means for moving the automatic guided vehicle, and transports the aerial mobile automatic guided vehicle correspondingly above the luggage inventory position, and stocks and ships luggage from above the luggage inventory position. This is the solution to the problem.

Effects of the Invention The present invention uses the above-mentioned problem-solving means to inventory and transport baggage by placing it from above or grabbing it from above at baggage inventory positions set separately on the floor, and reducing the weight of the load to be handled. In contrast, the weight of the logistics equipment can be kept small, making it possible to add additional equipment above the assembly line in terms of schedule and cost.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

As shown in the figure, the assembly equipment 1 is provided on the first floor, and a simple floor surface 2 is provided above. On this simple floor surface 2, a plurality of baggage inventory positions @ 3 are arranged and arranged in a manner that they are classified and assigned internal arrangement codes as a control system, and supply communication holes 4 to the assembly equipment 1 below are arranged. are placed. Above the simple floor 2 is an aerial mobile automatic guided vehicle (
A track 6 for driving an automated guided vehicle (hereinafter referred to as an automated guided vehicle) 6
The track 6 is connected to the cargo inventory position 3 and the supply communication hole 4.
They are arranged corresponding to the upper part, and furthermore, a branch point 7 is provided to branch the flow, so that the cargo can be transferred to a different inventory position 3 in a different column. The automatic guided vehicle 5 has a function of lifting and lowering cargo, and is capable of lowering and picking up cargo from above the cargo inventory position 3 using a lifting wire 8 and a cargo gripping mechanism 9.

To explain the operation in the above configuration, the control system causes the automatic guided vehicle 5 to stock or ship the luggage based on the inventory position information and the transportation information. At this time, since the baggage is placed and grabbed from above by the automatic guided vehicle 5 at the predetermined baggage inventory position 3 on the simple floor surface 2, there is no need for a movable part as a baggage storage area, and the baggage can be separated. There is no need for shelves or conveyors. Therefore, the load applied to the simple floor surface 2 is almost only the load of the luggage, and the structure of the simple floor surface 2 can be constructed with a simpler structure than in the past. In addition, simple floor surface 2
The height between the height and the ceiling can be the sum of the height of the cargo loading stage and the height of the track 6, the automatic guided vehicle 6, and the transported cargo, and it can be installed in the space within the factory without feeling oppressive.

As described above, according to the logistics device according to the embodiment of the present invention, the weight of the equipment such as shelves is small compared to the weight of the cargo to be handled, and the load of the logistics equipment is hardly applied to the floor surface, so it is possible to carry a large flat surface sube in a building. There is no need for installation or a dedicated building. In addition, recently factories are required to be able to respond quickly, especially when it comes to supplying parts, but it is possible to shorten the transportation distance in the assembly process trench, provide a logistics supply system with immediate response without undue stress on equipment costs and schedules, and switch production. Kayaji becomes easier.

Further, by providing a seat for stably placing the luggage and a guide body for preventing the inventory luggage from shifting in the luggage inventory position 3, more stable position control and accurate transfer can be achieved.

Effects of the Invention As is clear from the embodiments described above, according to the present invention, an aerial mobile automatic guided vehicle is transported above the cargo inventory position, and the cargo is stocked and shipped from above the cargo inventory position. This makes it possible to keep the weight of the logistics equipment small relative to the weight of the cargo being handled, making it possible to add equipment such as installing additional equipment above the assembly equipment, both in terms of schedule and cost, and to improve the market. We can provide production equipment that can fully respond to production changes for flexible production that meets demand.
