Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic warehouse in which a ceiling carrier equipped with a lifting lift is installed in a warehouse and operations for loading and unloading luggage are performed from outside the building.

[0002]

2. Description of the Related Art An automated warehouse is computer-controlled, and for example, when the code name and quantity of an item are entered, the item placed at the loading / unloading port is automatically carried to a vacant shelf. Is being speeded up. However, looking at the details of automation, there are many areas that are still insufficient. FIG. 4 is a block diagram of a conventional automated warehouse. Reference numeral 1 is an entrance / exit for goods near the entrance of the building 5 of the automated warehouse. 23 is an automated warehouse building 5
Conveyor station 7 inside, and the inlet / outlet 1
Is a carrier truck that carries goods back and forth between, for example, a magnetic tape laid on the floor. Reference numeral 7 is a conveyor station for temporarily placing the goods for loading and unloading them into a carriage and a conveyor. Reference numeral 8 is a stacker crane with an elevating lift for loading and unloading the articles on the shelf 3. 3 is a shelf for storing items. 20
Is used for inputting the code name, quantity, etc. of an item at the time of loading and unloading, giving an instruction 21 for loading or unloading to the carrier vehicle 23, and sending and receiving the second control panel 9 and predetermined data 22. It is one control panel. Reference numeral 9 is a control panel of the second control panel for instructing the location of the shelf 3 on which the articles corresponding to the stacker crane 8 are placed. FIG. 5 is a flow chart for explaining a conventional unloading operation of an automated warehouse. Necessary data such as the name and quantity of the goods to be delivered are input to the first control panel 20 installed near the entrance of the warehouse (STP10). Based on the instruction 21 supplied from the first control panel 20, the transport carriage 23 moves to the conveyor station 7 (STP11). The operator in the warehouse inputs predetermined data such as the location of the shelf 3 on which the corresponding item is placed into the second control panel 9 by checking stock storage data (STP12). Based on the instruction from the second control panel 9, the stacker crane 8
Takes out the bucket containing the corresponding item placed on the shelf 3 (STP13). The stacker crane 8
Carries the bucket to the conveyor station 7 and places it on the conveyor (STP14). The conveyor carries the bucket to the carriage 23 (STP15). The carrier truck 23 carrying the bucket moves to the loading / unloading port 1 (STP1
6). As described above, in the conventional automated warehouse, the stacker crane 8 takes out the buckets from the shelves 3 and the conveyor station 7 conveys the above-mentioned buckets to the transport carriage 23. I have a problem. Further, an operator is required for each of the first control panel 20 and the second control panel 9, which is a problem in terms of labor saving.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an overhead carrier equipped with a lifting lift is installed in a warehouse without reloading the goods between the loading / unloading port and the shelf. Moreover, it is an object of the present invention to provide an automatic warehouse in which one operator can carry in and carry out goods.

[0004]

In order to achieve the above object, a three-dimensionally installed shelves for storing goods and a designated goods are taken out from the shelves and carried to a conveyor station, or placed at a conveyor station. A crane with an elevating lift that moves around the shelves, a carriage that transports the goods by connecting the loading / unloading port of the goods and the conveyor station, and carrying in and out of the goods. An automated warehouse including an operation panel for instructing unloading comprises a ceiling carrier equipped with a lifting lift instead of the crane equipped with the lifting lift and the carrier.

[0005]

With the above-described structure, based on the instructions for loading and unloading the goods, for example, in the case of loading, the goods (bucket) at the loading / unloading port are placed on the shelves where the ceiling carrier with the lifting lift is vacant. Carry and store. Also, in case of unloading,
A ceiling carrier with an elevator lift arrives at the location of the shelf where the relevant item is stored, takes out the item, and transports it to the entrance / exit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The automatic warehouse according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram of an automated warehouse according to the present invention. Reference numeral 1 is an entrance / exit for goods. Two
Is a ceiling carrier with an elevator for carrying goods and taking them out of shelves. Reference numeral 3 is a three-dimensionally installed shelf for storing items. 4 is a warehouse building.
Reference numeral 6 denotes a control device for inputting data for carrying out or carrying in an item, performing predetermined data processing, and generating an instruction signal and the like.

FIG. 2 is a sectional view of the essential parts of an automatic warehouse according to the present invention. Reference numeral 11 is a rail which is installed between the shelves 17 on the ceiling beams 10 of the warehouse and the like in parallel with the shelves and reaches the entrance. 12 hangs down on the rail 11,
It is a ceiling carrier with a lifting lift that moves along. Reference numeral 15 is an elevating lift that moves the tip portion 16 of the lift up and down. Reference numeral 19 denotes an article take-out device provided on the tip portion 16 so as to move in the left-right direction in the drawing. 18
Is a bucket containing the items stored on the shelf 17.

The operation will be described. FIG. 3 is a flow chart for explaining the operation of leaving the automated warehouse according to the present invention.
An operator inputs data relating to the warehousing procedure to the control device 6 installed near the entrance / exit (STP1).
The control device 6 instructs the ceiling carrier 12 to specify the location of the shelving where the items are stored based on the relevant item and quantity, and the ceiling carrier 12 moves to the designated shelf location in the warehouse ( STP2). The elevating lift 15 of the ceiling carrier 12 operates, the tip 16 stops at a predetermined position on the shelf, and the article take-out device 19 moves to grab the bucket 18 and take it out of the shelf 17 and return to the predetermined position (STP3). The elevating lift 15 of the ceiling guided vehicle 12 winds and fixes the tip end portion 16 on which the bucket 18 is placed at a predetermined position, and then conveys the bucket 18 to the loading / unloading port (STP4). Although the warehousing operation proceeds in the reverse order of the warehousing operation, each operation is the same as the warehousing operation.
Further, although the ceiling transfer vehicle 12 is described as one unit, a plurality of units may be operated.

[0009]

As described above, according to the present invention, a ceiling carrier equipped with an elevating lift is installed in a warehouse, and goods are not transshipped between a loading / unloading port and a shelf, and one operator can carry in the goods. Provide an automated warehouse for unloading. Therefore, it is possible to realize an automated warehouse that has a speed of loading and unloading and has a function of saving labor. In addition, a conveyor and a conveyor station are not required, space can be saved, and the flexibility of layout in the warehouse can be improved.
