Embodiment Construction

[0058] [Overall structure of warehouse system]

[0059] 〈Outline structure〉

[0060] figure 1 It is a schematic structural diagram of the warehouse system which concerns on one Embodiment of this invention.

[0061] The warehouse system 300 includes a central control device 800 (control device) for overall control, a warehouse 100 for storing items in stock, a temporary storage device 104 for temporarily storing items to be shipped, and a centralized inspection site for collectively inspecting items to be shipped 106. A packaging site 107 for packaging the inspected items and a delivery machine 108 for delivering the packaged items to delivery trucks and the like.

[0062] The warehouse 100 is a place where an automatic guided vehicle (AGV) described later works, and includes storage racks for storing articles therein, a transport robot (not shown), an arm robot 200 , and a sensor 206 . Here, the sensor 206 includes a camera or the like that captures an image of the entire ...

Abstract

The warehouse system of the present invention includes: an arm robot (200‑1~200‑n) capable of taking out items from a storage rack; a handling robot that carries the item together with the storage rack within the operating range of the arm robot; a robot that can store the original teaching data Robot teaching database (229), the original teaching data is based on the coordinate model value of the storage rack as the model value of the 3-dimensional coordinate of the storage rack and the coordinate model value of the manipulator as the model value of the 3-dimensional coordinate of the manipulator; A sensor (206) of the relative positional relationship between the frame and the manipulator; and a robot data generation unit (264, 230), which corrects the original teaching data based on the detection result of the sensor (206) to generate the robot provided to the arm robot (200). Teaching data (θ1'~θn').

Description

technical field [0001] The present invention relates to warehouse systems. Background technique [0002] Robots that carry goods from one location to another are called unmanned guided vehicles or AGVs (Automatic Guided Vehicle: automatic guided vehicles). AGVs are widely introduced in facilities such as warehouses, factories, and ports. Furthermore, by combining and using a loading and unloading device that automatically performs delivery of goods between the storage place of the goods and the AGV, that is, the loading and unloading work, most of the operations of logistics in the facility can be automated. [0003] In addition, due to the diversification of customer needs in recent years, warehouses that handle a variety of small quantities of goods, such as mail order warehouses, are increasing. Given the nature of the items being managed, time and personnel costs are spent in searching for the items, carrying out the loading. Therefore, in the warehouse for mail order...
