  With reference to FIGS. 1 and 2 showing a conventional luggage storage system with respect to the arrangement of the conveyor, the luggage 112 is stored on the second floor of the warehouse 110, and the main conveyor 114 extending in the center of the first floor of the warehouse 110 is stored. And a number of sub-conveyors 116 branched from the main conveyor to the left and right.

  The main conveyor 114 receives the package 112 on the second floor of the warehouse 110, conveys the package 112 to the first floor, sorts the package according to the delivery direction, and delivers it to the corresponding sub-conveyor 116. Each sub-conveyor 116 receives the cargo 112 sorted according to the delivery direction from the main conveyor 114 and conveys it toward the vehicle 118 prepared for each delivery route. Near the end of each secondary conveyor 116, the load 112 is unloaded from the secondary conveyor by the operator and placed in the conveyor peripheral zone 120A on the floor 120.

  After that, the luggage 112 is loaded on the car or cart 122 by the operator and carried to the storage zone 120B on the floor 120 as preparation for loading on the vehicle 118 according to the delivery route.

  When a load 112 loaded on a vehicle corresponding to a specific delivery route, for example, one vehicle corresponding to the Route 1 route toward Tokyo, is collected in the storage zone 120B, the worker or the driver of the vehicle 112 is taken into consideration in order of delivery and loaded into the vehicle 118.

  A device or a system for delivering a package conveyed by the main conveyor 114 to the sub-conveyor 116 according to the delivery direction and the delivery route is widely known. Since loading into is also common practice, a detailed description of these will be omitted.

  The disadvantage of conventional baggage handling is that the baggage 112 is required in the peripheral zone 120A of the sub-conveyor 116 and the storage zone 120B between the vehicle 118 and the sub-conveyor 116, which is required as a temporary storage place or a sorting place for delivery. This requires a large area depending on the amount of work, and therefore a large number of workers must be placed in those zones. Another drawback is that it is difficult and impossible for the operator to pick up the cargo placed in the peripheral zone 20A and the storage zone 20B according to the loading order, which causes various human errors. It is easy.

  Therefore, the main object of the present invention is to reduce the area of the zone around the conveyor that receives the load from the main conveyor and the zone between the conveyor and the vehicle, and reduce the load and number of workers placed in those zones. It is to reduce human error as well as to reduce.

  In order to achieve the above object, the present invention has a main conveyor for delivering a load to a load receiving conveyor arranged on the inner periphery of a work area at an overhead level on the first floor of a building, and a multi-stage storage conveyor in a space immediately below the load receiving conveyor. The three-dimensional installation reduces the area of the zone required around the load receiving conveyor, and the storage conveyor end is located under the main conveyor facing the vehicle outside the work area. The basic concept is to reduce the area of the zone to a minimum, thereby reducing the floor space required for effective use of the warehouse floor and reducing the number of personnel required for loading work.

A plurality of load storage devices for storing loads received from the main conveyor, the other end disposed in the work area, the load storage device comprising a plurality of support posts and a load support supported by the support posts. A conveyor, a plurality of storage conveyors below the consignment conveyor and supported by the struts spaced from each other, and adjacent to an end of the consignment conveyor opposite the main conveyor A transfer conveyor for receiving a load from the load receiving conveyor and transferring the load to the storage conveyor; and the transfer conveyor and the storage conveyor. And a lifting device for lifting between yer, the storage conveyor is characterized in that and is moved in the opposite direction storage and conveyance direction of the load receiving conveyor luggage received from the loaded replacement conveyor.

  A pair of luggage storage devices can be placed back to back between the main conveyors. The package storage device stores packages received from the main conveyor and sorted according to delivery direction but not sorted in the order of delivery.

  The storage conveyor is preferably cantilevered on the support column. The package is provided with a medium of information about a delivery direction and a delivery order on a surface opposite to the transport direction of the main conveyor, and the main conveyor, the load receiving conveyor, and the lifting device include When delivered to the storage conveyor, the load is transported so that the surface of the load is directed to the opposite side of the storage conveyor from the column. As a result, the worker can always handle the luggage while facing the medium.

  The main conveyor, the load receiving conveyor, and the transfer conveyor are each a drive conveyor, and the drive conveyor is a roller conveyor or a belt conveyor.

  On the other hand, the storage conveyor is a free roller conveyor. The storage conveyor can also be a drive conveyor. Each storage conveyor is preferably arranged so that its terminal end is located on one end side of the load receiving conveyor.

  According to the present invention, the main conveyor for delivering the load to the load receiving conveyor is arranged on the inner periphery of the load handling work area and above the floor surface, and a multi-stage storage conveyor is three-dimensionally installed in the space immediately below the load receiving conveyor. This reduces the area of the zone required around the receiving conveyor and reduces the area of the zone required for loading on the vehicle by placing the end of the storage conveyor in the vicinity of the vehicle. In addition to halving the required area of the area, by reducing the area of both zones, it is possible to improve the work efficiency of baggage handling and reduce the burden on the operator and work errors.

  Referring to FIGS. 5 to 8 showing the load storage device 18 in more detail, the load storage device includes a load receiving conveyor 26 that is cantilevered by a plurality of columns 24. The load receiving conveyor 26 is at approximately the same height level as the main conveyor 16. The load receiving conveyor 26 is also a drive conveyor, and in the illustrated example, is a roller conveyor. Alternatively, the load receiving conveyor 26 can be a belt conveyor.

  In the space below the load receiving conveyor 26, a plurality of storage conveyors 28 (three stages in the example shown in FIG. 7) which are similarly cantilevered by the support columns 24 at intervals are arranged. The storage conveyor 28 can arbitrarily increase or decrease the number of stages according to the type of baggage and the average size. As the number of stages increases, the area of the work area 14 can be reduced.

  As shown in FIGS. 7 and 9, the load storage device 18 includes a transfer conveyor 30, which is disposed adjacent to an end of the load receiving conveyor 26 opposite to the main conveyor 16. The transfer conveyor 30 is also a drive conveyor, and may be either a roller conveyor or a belt conveyor. After receiving the load 12 from the load receiving conveyor 26, the transfer conveyor 30 delivers the load to the storage conveyor 28 of each stage. Therefore, the luggage storage device 18 includes an elevating device 32 that raises and lowers the loading conveyor 30 between the cargo receiving conveyor 26 and each storage conveyor 28.
