Definitions
- This disclosure relates to a machine.
- Each of the multiple actuators includes a motor, an amplifier, and the like.
- the multiple actuators or the amplifiers of the multiple actuators are connected to each other via a bus connection or a daisy chain connection. This allows current from an external power source to be supplied to each of the multiple actuators (see, for example, JP 2015-093329 A).
- each actuator requires both an input terminal and an output terminal.
- the actuator board area becomes larger, and the actuator becomes larger. This means that machines equipped with multiple actuators also become larger.
- the actuator in the case of bus connection, it is sufficient for the actuator to have one terminal.
- soldering or branching work using a branch connector is required. This reduces the reliability of a machine equipped with multiple actuators, and also requires space to perform the branching work. This causes the problem of the machine becoming larger.
- a machine includes a first actuator and a second actuator, a first wire that connects an external power source to the first actuator, a first wiring section provided on the first wire, and a second wire that connects the second actuator to the first wiring section.

- Each of the first to sixth axes is perpendicular to the other adjacent axes.
- the first to sixth actuators 5a to 5f are arranged inside the robot 1f in correspondence with the first to sixth axes, respectively.
- a first group 51 is shown, which is made up of three or more actuators, 5a-5c.
- a first wire L1 connects the external power source 10 to one of the actuators in the first group 51, 5a.
- a first wiring section 21 is also disposed on the first wire L1.

- the second wiring portion 22 is provided on the third wire body L3.
- at least one additional wire body L4-L6 is arranged to connect at least one actuator 5d-5f in the second set 52 to the second wiring portion 22.
- wiring units 21, 22 and filaments L1-L6 are arranged on robot 1f based on the configuration in FIG. 3.
- first wiring unit 21 is arranged near first arm member 11 of robot 1f, and can also be mounted inside first arm member 11. Furthermore, first arm member 11 is located on the base end side of robot 1f. Sixth arm member 16 of machine 1f almost never moves near first arm member 11, and therefore there are no space issues with first wiring unit 21.
- the second wiring part 22 is disposed inside the second arm member 12 which is rotatably connected to the first arm member 11. Therefore, the presence of the second wiring part 22 does not change the external shape of the robot 1f, for example, the external shape of the second arm member 12. Therefore, there are no space problems with respect to the second wiring part 22.
- each of the groups 51, 52 is equipped with wiring units 21, 22.
- the reason for this is that by arranging the wiring units 21, 22 in a location in the machine 1f where there is ample space, it is possible to avoid the machine 1f becoming larger. Therefore, it is particularly advantageous to apply the configuration shown in Figure 3 to a 6-axis vertical articulated robot 1f as shown in Figure 5.
- the effect of at least one of the embodiments described above is that the actuator only needs to be provided with a single terminal, and therefore the actuator and the machine do not need to be made larger.
- a space-saving machine consisting of multiple actuators with only one terminal can be provided.
- soldering or branching processing using a branch connector is no longer necessary, which can increase the reliability of the machine.
- (Appendix 1) A first actuator and a second actuator; A first umbilical member that connects an external power source and the first actuator; A first wiring portion provided on the first filament; a second wire member connecting the second actuator and the first wiring portion.
