[0007] In addition, the present invention may further include a vertical conveying means that is provided so as to be capable of conveying the automatic conveying means, and the vertical conveying means may be provided so as to be capable of communicating with the automatic conveying means. In addition, the present invention may be configured so that the vertical conveying means is composed of a plurality of units, and the plurality of units include at least a top unit, a middle unit, and a bottom unit. In addition, the present invention may be configured so that the plurality of units further includes a spacer unit. Effect of the Invention

The self-propelled conveying means 1 is capable of moving between the initial position and the loading platform installation E by reading the tape with the sensor. The guidance system of the self-propelled conveying means 1 is not limited to the route guidance system, and may be an autonomous moving system, in which case the self-propelled conveying means 1 has a position estimation means, for example, an optical wave distance meter, a camera, a gyro sensor, etc.

[0015] The loading platform 3 is installed at the work site to carry in the equipment M carried by the automatic transport means 2 to the work site, and is provided with an in-loading transport means 10. The in-loading transport means 10, together with the out-loading transport means 7, constitutes a transport path 11 for carrying the equipment M from the self-propelled transport means 1 to the loading platform 3, as described below.

[0016] In this embodiment, the receiving platform 3 has a configuration substantially similar to that of the placement section 6 of the automatic transport means 2, the carry-in side transfer means 10 is provided as a conveyor, and the receiving platform 3 is provided with a stopper section 12 for fixing the equipment M during storage of the equipment M. Also, in this embodiment, a stop mark (not shown) is provided at the receiving platform installation position E, and the automatic transport means 2 is adapted to stop at the position of the stop mark, whereby the automatic transport means 3 and the receiving platform 3 are arranged in parallel to form a transport path 11.

[0017] The vertical conveying means 4 is connected to the floor S on which the receiving platform 3 to which the automatic conveying means 2 is to be delivered is installed. G The vertical conveying means 4 has an elevation gauge 13 on which the automatic conveying means 2 can board, an elevation means for the elevation gauge 13, for example, a hoist 14, and an entrance 15 provided on each floor S, and is provided so as to be able to communicate with the automatic conveying means 2. In this embodiment, the entrance 15 is provided with a gate unit 16 that can be opened and closed, and a stop line (not shown) is provided in front of the gate unit 16.

[0018] In this embodiment, the vertical conveying means 4 is composed of a plurality of units 17, so that it can be easily assembled and disassembled at a construction site, etc. Each unit 17 is provided so that an entrance 16 provided in the unit 17 is connected to each floor S of a building under construction, etc., and the plurality of units 17 includes a top unit 17 T and Intermediate Unit 17 M and bottom unit 17 B and,

[0019] Bottom unit 17 B The bottom unit 17 constitutes the lowest floor of the vertical conveying means 4, and usually, when the equipment M is carried into the work site, the automatic conveying means 2 B You will board the elevator to gauge 13 through the entrance.

[0020] Top unit 17 T constitutes the top floor of the vertical conveying means 4, and is equipped with a hoisting machine 14. In this embodiment, the hoisting machine 14 is composed of a wire 18 that suspends the lifting gauge 13 and a main body 19 that winds up the wire 18.

[0022] Next, a transfer process of the transfer system 1 of this embodiment will be described. (1) Prior to this, for the automatic transport means 2, the operation start time and the transport destination are specified, and the equipment M is placed on the placement unit 6. At this time, in this embodiment, the tray T is placed on the placement unit 6, and the equipment M is placed on the placement unit 6 via the tray T. The automatic transport means 2 operates at the specified time and checks the safety of the surroundings by the safety confirmation means. Note that the placement of the equipment M on the automatic transport device 2 may be performed manually or may be automated using a robot or the like (not shown).

[0023] (2) The automatic transport means 2 moves to the vertical transport means 4 and stops at the stop line. As a result, the vertical transport means 4 operates and communicates with the automatic transport means 2 to obtain the transport destination from the automatic transport means 2.

[0024] (3) When the gate portion 16 of the lift opening 15 of the bottom unit 17 B opens, the automatic transport means 2 enters the vertical transport means 4 and gets on the lift gauge 13. After that, the gate portion 16 closes, and the lift gauge 13 moves up and down to the floor S G where the receiving platform installation position E, which is the transport destination, is located.

[0025] (4) The gate portion 17 leading to the floor S G where the receiving platform installation position E, which is the transport destination, is located, opens, and the automatic transport means 2 receives this information. When the automatic transport means 2 receives this information, it checks the safety of the surroundings by the safety confirmation means, gets off the lift gauge 13, and when the automatic transport means 2 stops at the stop line, the gate portion 17 is closed.

[0026] (5) The automatic transport means 2 moves to the receiving platform installation position E and stops at the stop mark. At this time, the unloading side transfer means 7 and the loading side transfer means 10 are in a parallel state, and the unloading side transfer means 7 and the loading side transfer means 10 form a transport path 11 for loading the equipment M onto the receiving platform 3. The unloading side transfer means 7 and the loading side transfer means 10 are operated to transport the equipment M to the receiving platform 3. Thereby, the transport of the equipment M to the work site is completed.

[0027] (6) After that, the automatic transport means 2 reverses the above steps and returns to the initial position, where a stop mark is provided in the same manner as the loading platform installation position.

[0028] Therefore, in the conveying system of this embodiment, by providing the automatic conveying means 2 and the loading platform 3 as described above, it is possible to automate the conveying of the equipment M.

[0029] Although the present invention has been described based on the above embodiment, the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit and scope of the invention.

[0030] For example, the multiple units 17 of the vertical conveying means 4 can include spacer units (not shown). The spacer units are provided to adjust the height of the units 17 when the height of each unit 17 does not match the height of the story S of the building, etc., because the height of the story S of the building, etc. differs depending on the building, etc., resulting in a misalignment between the entrance 15 of the unit 17 and the story S of the building, etc. [Explanation of symbols]
