Description

  The present invention relates to a transport system for transporting a baggage of a boarding customer on a transport pass box (hereinafter referred to as “tray”) at an airport or the like.

  In general, baggage of boarding customers is consigned from the customer before boarding at the airport, etc., then given a baggage identifier ID, and is automatically transported to the designated aircraft on the conveyor belt according to the departure time. . Thereafter, the baggage that is airlifted to the destination by the aircraft is automatically transported to the customer at the place where the baggage is received at a specified time.

  All these baggage are sorted and transported by the transport system according to the flight number, destination, etc. Baggage is read by the baggage identifier ID reader in the transport mechanism and automatically transported to the boarding machine within the specified time. After the aircraft is transported, it is transported by a conveyor belt to reach the specified location at the arrival airport. Each route is branched and conveyed.

  In such a baggage transfer system for passengers, a wide belt conveyor has been used in the past, but in a transfer system using a wide and long belt made of flexible resin, etc., it is driven by a driving motor or the like. Not only is the electric power large, but the speed is limited and the maintenance (inspection / repair) is very complicated.

  In recent years, in baggage transport at airports, a belt conveyor (narrow belt), rollers, and no A high-speed baggage transport system is used in which a transport path composed of a driving roller or the like is used, or a load is placed on a self-propelled carriage and the surface of the transport path is moved.

  In this way, the optimum tray transport (baggage tray placement transport) for accurately transporting customer baggage at high speed and accurately to all designated destinations is generally adopted. There are various problems.

  For example, Patent Document 1 discloses a general technique of a transport system in an automatic warehouse, in which empty trays are stacked and stored in a storage space, and taken out to a transport path as needed. It is essentially efficient because it is efficient to stack and store the trays, and it must temporarily stand in a stock yard off the conveyance path and requires a large space. Absent.

  In Patent Document 2, an empty tray is stored in a storage space called a reservoir in a warehouse system. However, the storage space is temporarily placed in a reservoir that is out of the conveyance path only by placing the storage space in an efficient position. It is not efficient because it requires a large amount of space and requires a large space.

  The destination-designated article tray mounting and transporting system according to the present invention is a space for storing 1 to 12 empty trays inside a substantially linear transporting device unit constituting the transporting path, more specifically, at the lower part of the transporting path surface. And an empty tray can be stored from the conveyance path as needed, or conversely, an empty tray can be taken out and moved onto the conveyance path.

  Depending on the length and height of the transport device unit and the length and height of the empty tray, the empty tray storage space can be provided in about 1 to 3 steps below the transport path surface of the transport device unit. In order to store and remove the empty tray in the storage space, empty tray moving means such as a conveyance belt driven by a motor can be installed on both sides in the same manner as the conveyance path surface. If necessary, the empty tray storage space may be provided with a sensor for detecting the presence or absence of an empty tray, a storage space, and a cushion mechanism for receiving the empty tray at the end portion.

  Although the number of empty trays that can be stored in the storage space depends on the length of the transport device unit and the length of the tray, the number of empty trays may be about 1 to 4 per stage and about 1 to 12 per transport device unit. it can.

  In the destination-designated article tray mounting and conveying system according to the present invention, an empty tray that moves on the conveying path is placed in the tray storage space of the conveying device unit, or conversely, an empty tray that is stored is moved on the conveying path. This control can be performed by software that manages trays in the entire transport path. The command from the entire tray management software may be sent to the control unit of the transport unit so that the tray can be taken in and out.

  Means for putting an empty tray that moves on the conveyance path into the tray storage space of the conveyance device unit, or conversely moving the empty tray stored on the conveyance path, is connected adjacent to the conveyance device unit, for example, up and down. A tray lifting / lowering unit having a moving lift may be used, or a sorting unit that is inclined at an angle connected to a designated storage stage may be used. Even these tray lifting / lowering units and the inclined sorting unit may have means for moving the empty tray using a driven conveyor belt or the like when the empty tray is taken in and out of the conveyance path.

  The destination designation article tray mounting conveyance system concerning the present invention can also be made into the mode which uses a drive roller as a means to move an empty tray. For example, the drive roller is driven by software stored in the control unit of the transport unit, but the required drive roller may be sequentially driven according to the presence or absence of the tray in the tray storage space.

  The destination-designated article tray mounting and transporting system according to the present invention provides a temporary stock and storage of so-called empty trays after transporting articles, without providing a conventional storage warehouse and storage space, and a lower empty space on the article conveyor transport path. This is a technical idea that is utilized rationally as a connected empty tray storage conveyance path and / or storage storage space, and all equivalent methods using the prior art are included in the technical idea of the present invention. .

Since the configuration, shape, and the like shown in the drawings are examples of the embodiment of the present invention, the present invention is not limited to what is illustrated in the drawings.

  FIG. 1 is a conceptual view seen from the side of a transport unit having an empty tray storage space inside a destination designated article tray mounting transport system according to an embodiment of the present invention. As shown in the figure, a substantially straight portion of the transport path is configured and a transport apparatus unit having a certain length, and has an empty tray storage space 110 inside. On the conveyance path surface, there is a conveyor belt 10 that is slightly narrow on the left and right in the conveyance direction, and the conveyor belt 10 is driven by a drive motor 20 via a drive roller 21. Cargoes and transport trays transported by conveyor belts arranged and driven on both sides in the traveling direction move, but are guided by tray guides 50 on the left and right so that they do not jump out of the transport path.

  Specifically, a three-stage empty tray storage space 110 is provided in the lower part of the transport path inside the transport unit. In the empty tray storage space of each stage, a conveyor belt 15 having a slightly narrow width is arranged in the same manner as the conveyance path, and is used for moving the empty tray 70 to be taken in and out. The conveyor belt 15 for moving the empty tray in each stage is driven by a storage unit drive roller 22 driven by a storage unit drive motor 25.

  The empty tray has a weight of 70 and is also supported by a non-driven roller 23 located under the conveyor belt. In addition, the presence or absence of an empty tray in each space is detected by a tray storage unit sensor 40 or the like, and management software installed in the control unit 30 receives a command from a control unit (not shown) that manages the entire conveyance path. The empty tray is inserted and removed by driving the drive motor of the storage unit.

  FIG. 2 is a conceptual diagram viewed from the side of a transport apparatus unit having an empty tray storage space inside a destination-designated article tray mounting transport system according to another embodiment of the present invention.
