Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power transmission / distribution device used for electric wiring. More specifically, the present proposal relates to a power transmission / distribution device used for wiring in a module conveyor.

[0002]

[Prior Art]

 Module conveyors that can be used in combination of several to several hundreds or can be used independently include conveyor components such as rollers and belts, motors that drive them, and power transmission and distribution devices for wiring. Is provided. The power transmission and distribution device is used not only to supply power to the drive motor but also to be used as a power source for the assembly robots and tools used on or near the module conveyor. It is needed to prevent it.

Conventionally, as such a power distribution device, for example, the power distribution devices disclosed in Japanese Patent Laid-Open No. 63-1842765 and Japanese Utility Model Laid-Open No. 60-170985, which are mainly used for power distribution in factory facilities, can be cited. As shown in FIG. 5A, this power distribution device has three conductor rods 102, 102, 102 for three-phase power supply and two conductor rails 103, 103 for 100V power supply in a duct 101. Each is arranged in parallel. This power distribution device has an opening 104 on the bottom surface side of the duct 101, from which a plug having a special structure is inserted into the duct 101 and hooked on the conductor rod 102, 102, 102 or rail 103, 103 described above. In this way, a 200V or 100V concentrator is provided at an arbitrary position. In addition, as shown in FIG. 5B, this power distribution device is provided with a connector 105 called a feed-in cap for introducing power to the power transmission / distribution duct 101, which is the terminal, while the other duct has a pin shape. Feed-in terminals 106 and rail-shaped feed-in terminals 107 are provided, and the feed-in terminals 106, 107 are used to connect the power transmission / distribution ducts 101, 101, ... Is configured to obtain 101. The feed-in cap 105 includes a terminal block 108 electrically connected to the conductors 102 and 103 in the duct 101 through feed-in terminals 106 and 107, a power supply intake pipe 109, and a space 110 for wiring. Is provided and is covered with the cap 111.

The present inventors have considered using this power distribution device as a power distribution device for a module conveyor. The power transmission / distribution duct 101 is installed at the bottom of the pedestal 113 of each module conveyor 112a, ..., 112n, and provided with feed-in caps 105, 105 at both ends thereof, respectively. The cable 105 and the cable 114 are connected to each other (see FIG. 6). Reference numeral 115 is a plug having a special structure.

[0005]

[Problems to be solved by the device]

 However, in the case of a module conveyor, the power transmission and distribution device itself is required to be divided into modules and to be independent. Therefore, the power transmission / distribution ducts 101, 101, ..., 101 of the module conveyors 112a, 112b, ..., 112n respectively require feed-in caps 105, 105 for receiving power at both ends thereof, which is expensive. The problem arises.

Moreover, since the feed-in caps 105, 105 are arranged at both ends of the power transmission / distribution duct 101, there is a problem that the substantial length of the power transmission / distribution duct 101 is shortened and the number of plugs that can be set is reduced.

Further, in order to connect the power transmission / distribution ducts 101, 101 of the adjacent module conveyors, the feed-in caps 105 must be connected by the cables 114, respectively. Therefore, the power transmission / distribution ducts 101, 101 are connected to each other. There is a problem that the original advantage of easily obtaining a long wiring is lost by directly fitting with the pin- or rail-shaped feed-in terminals 106 and 107.

Further, as the outlets or plugs 115, ..., 115 for extracting the power source, outlets or plugs having a general structure cannot be used, and a special structure must be used, resulting in high cost. There is a problem that becomes.

Further, the connection of the power transmission / distribution ducts 101, 101, ..., 101 of the module conveyors 112a, 112b, ..., 112n is performed by a pin-shaped or rail-shaped feed-in as shown in Japanese Utility Model Publication No. Sho 60-17098. When using the terminals 106 and 107, when disconnecting the ducts 101 and 101 to replace or remove the module conveyor 112 in the middle, all the module conveyors 112a, 112b, ..., 112n are fed-in terminals. It is necessary to move the 106 and 107 sequentially in the longitudinal direction to disconnect the pins and the like, and then remove the corresponding module conveyor. Therefore, it is virtually impossible to replace or remove the modular conveyor in the middle of a production line of a factory with hundreds of connected units.

The present invention can be manufactured at a low cost because the number of outlets per duct can be increased and the contents can be used with an inexpensive and simple general structure. An object is to provide a power transmission and distribution device. Another object of the present invention is to provide a power transmission and distribution device that simplifies electrical connection between power transmission and distribution ducts and can easily replace or remove a module conveyor.

[0011]

[Means for Solving the Problems]

 In order to achieve such an object, the power transmission and distribution device of the present invention is a power transmission and distribution device used for a module conveyor, and includes a power transmission and distribution duct containing a conductor for power transmission and distribution, and a conductor installed in advance in the duct. A plurality of outlets connected in parallel, a terminal on the free side of the conductor arranged at one end of the power transmission / distribution duct, and a conductor connected to the other side of the power transmission / distribution duct at the other end of the power transmission / distribution duct. It is provided with fixed side terminals that can connect the side terminals.

Further, the power transmission and distribution device of the present invention is provided so as to be movable in the length direction of the power transmission and distribution duct, and a free side terminal at one end of the power transmission and distribution duct and a fixed side terminal of another power transmission and distribution duct connecting the same. And a connection cover for covering and.

[0013]

[Action]

 Therefore, by connecting the free side terminal of the conductor at one end of the power transmission / distribution duct to the fixed side terminal of the conductor at the other end of another adjacent power transmission / distribution duct, Can be used by connecting them together.

Furthermore, if the connecting cover at the end of the power transmission / distribution duct is pulled out and fixed to another adjacent duct after the conductors are connected, the connecting portion of the free side terminal and the fixed side terminal is covered with the connecting cover.
