Notogawa Plant (8) Publisher: Office Space Co., Ltd.; Publication name: General Civil Engineering Technology Journal, Civil Engineering Construction, Vol. 63, No. 1; Publication date: December 22, 2021 This invention relates to a rebar assembly system and assembly method for assembling a rebar structure that includes reinforcing bars arranged in two upper and lower tiers. Traditionally, the assembly of reinforcing bars—placing them in designated positions and tying them together—has been performed manually by workers. Various methods have been proposed to improve the efficiency of this reinforcing bar assembly process. For example, Patent Document 1 discloses a rebar assembly system that automatically performs rebar supply, placement, and tying using a robotic arm or the like. Japanese Patent Publication No. 2021-049567 A schematic perspective view showing a factory where the rebar assembly system according to the embodiment is installed.Perspective view showing a reinforced concrete assembly system according to an embodiment.Perspective view of a reinforced concrete member including reinforcing bars assembled by the reinforcing bar assembly system according to the embodiment.Reinforcement diagram of a reinforced concrete member including reinforcing bars assembled by the reinforcing bar assembly system according to the embodiment.Front view showing the gripping device of the rebar assembly system according to the embodiment.Front view showing the upper reinforcement tying machine of the reinforcement assembly system according to the embodiment.An explanatory diagram showing the reinforcement bar placement procedure using the reinforcement bar assembly system according to the embodiment. The embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a schematic perspective view showing a factory 2 where the rebar assembly system 1 is located. Factory 2 includes a temporary material storage area 4 for temporarily storing materials such as rebars 3, a rebar assembly area 5 for assembling the rebars 3, and a temporary assembled rebar storage area 6 for temporarily storing assembled rebars 3. Materials are transported from the temporary material storage area 4 to the rebar assembly area 5, and from the rebar assembly area 5 to the temporary assembled rebar storage area 6, by a gantry crane 7. Figure 2 is a perspective view showing a rebar assembly system 1 located in the rebar assembly area 5. The rebar assembly system 1 comprises a plurality of rebar supply machines 8 for storing and supplying rebars 3 before assembly, an individual rebar conveyor 9 for transporting the rebars 3 supplied from the rebar supply machines 8, an assembled rebar conveyor 10, a rebar stand 11 supported by the assembled rebar conveyor 10, a gripping device 12 capable of gripping rebars 3, an upper rebar tying device 13 (see Figure 6) for tying the rebars 3 located on the upper level, a robot arm body 14 whose base end is immovable and to which the gripping device 12 and the upper rebar tying device 13 can be selectively attached, and a lower rebar tying device 15 for tying the rebars 3 located on the lower level (the rebar supply machines 8 and individual rebar conveyor 9 on the left side of Figure 2 are omitted from the illustration). The robot arm 16 is constructed by attaching the gripping device 12 or the upper rebar tying device 13 to the robot arm body 14. With the gripping device 12 attached, the robot arm 16 grips the reinforcing bars 3 that have been transported by the individual reinforcing bar conveyor 9, places them on the reinforcing bar stand 11 on the assembled reinforcing bar conveyor 10, and with the upper reinforcing bar tying device 13 attached, ties together the intersecting parts and the parts that constitute overlapping joints of the reinforcing bars 3 arranged on the upper level. Figure 3 shows a precast concrete member 17 including reinforcing bars 3 assembled by the reinforcing bar assembly system 1 (see Figure 2), and Figure 4 shows the reinforcement diagram. The precast concrete member 17 is a component of which many identical structures are manufactured, and is, for example, a component t
