[Technical field to which the invention belongs]

 The present invention relates to a generator-integrated EF (electrofusion) controller. Specifically, in an EF controller used to connect an electrofusion joint (hereinafter, referred to as an EF joint) that connects a gas pipe made of a plastic pipe by an electrofusion method (hereinafter, referred to as an EF method), a generator is integrated with the EF controller. The present invention relates to an integrated EF controller provided.

[Prior art]

 Conventionally, in plumbing work with plastic pipes such as water and sewage and gas pipes, plastic T-joints, elbow joints, socket joints, saddle joints, etc. are used, and the inner surface and the outer surface of the plastic tube are heated and melted by a heater. In this state, a plastic pipe was inserted into the joint and connected. However, recently, the EF method has been adopted to improve workability and connection quality.

A method of connecting a plastic pipe by the EF method will be described with reference to FIG. In the figure, 1, 1 'are two plastic tubes to be connected, and 2 is an EF joint. This EF joint is a plastic tube in which a coil-shaped heating wire 3 is embedded in advance. One end of the heating wire 3 is connected to a terminal pin 4 and the other end is used to identify the type of the joint. Is connected to the terminal pin 5 having the identification resistance of

Then, the plastic pipes 1, 1 ′ to be connected from both ends of the EF joint 2 are inserted until they abut against the stopper 2 a, and the connector cables 7, 7 ′ from the controller 6 are connected to the terminal pins 4, 5. I do. As shown in FIG. 5, the controller 6 has two connector cables 7, 7 'having a connector 8 and a power cable 9. An operation panel 11 is provided on the upper surface of the controller 6, and The panel 11 is provided with a power switch 12, a start switch 13, a reset switch 14, a temperature sensor 15, a fusion time display section 16, an abnormality display section 17, and the like.

When the power cable 9 is connected to the power source and the power is turned on, the controller 6 reads the identification resistance of the terminal pin 5, identifies the type of the EF joint, and identifies the EF joint based on the outside air temperature detected by the temperature sensor 15. The current application time suitable for the type is set and displayed on the fusion time display section 16. At this time, if there is an abnormality such as an input voltage abnormality, an output voltage abnormality, a fusion abnormality, a disconnection, a disconnection of a connector, etc., the abnormality is displayed on the abnormality display section 17. If there is no abnormality, a predetermined current is supplied to the EF joint 2 for a predetermined time. As a result, the heating wire 3 generates heat and melts the inner surface of the EF joint 2 and the outer surface of the plastic pipes 1 and 1 'to join them together.

[0006]

[Problems to be solved by the invention]

 In such a conventional controller for an EF joint, power is often supplied from an engine generator. The generator and controller were selected independently, and both were connected by cables. In this case, depending on the generator, the controller, and the fusion joint, there is a problem that an appropriate power generation output cannot be obtained and a normal fusion operation cannot be performed. Also, in general, it is determined that one EF controller is used independently for one generator (without using other loads at the same time). However, there is a problem that it may not be executed. there were. Furthermore, the conventional EF controller alone is required to be small and lightweight, have good working of cables and the like, and have a good working environment (with respect to earth, sand, water, and impact). there were.

[0007] In view of the above-mentioned conventional problems, the present invention provides an EF controller in which a generator is provided integrally with the controller, whereby an appropriate power generation output is obtained and a generator that is suitable for a work environment. An object is to realize an integrated EF controller.
