Description

Socket type automatic welding device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fusion apparatus for melting and joining plastic pipes, and more particularly, to a socket type automatic fusion apparatus for fusion between pipes by controlling the temperature of a heating wire in an electric fusion sleeve tube according to a preset fusion parameter. It is about.

In general, plastic pipes are used for various purposes because they have no advantage of corrosion and have the advantages of semi-permanent life and low material cost and construction cost unless artificial damage is caused. In addition, because of its flexibility, it is easy to pipe on any terrain, and there is no substance dissolving in the pipe itself, so it is mainly used for water pipes, gas pipes, sewer pipes, etc. Wide range of applications However, in order to safely transport and store materials such as gases or chemicals, which are dangerous substances when installing plastic pipes, the joints of pipes must be firmly joined.

To this end, the joining of the plastic pipes is performed by directly fusion of the plastics themselves with heat without using other materials to join the pipes, which is called welding.

The welding method is divided into butt welding, socket welding and saddle welding. Among them, the socket welding device is classified into a hot tool using welding machine and an electrofusion welding machine according to the type of the socket.

In the same way as the butt method, the socket welding device using a hot tool is to weld the end face of the plastic pipe by using a heater, whereas the electric melting socket welding device supplies a constant voltage and current to the sleeve for the electric welding in the sleeve pipe. By heating the heating wire, the outer surface of the pipe is melted to fuse the plastic pipe.

1 is a view showing a conventional socket-type welding device.

As shown in FIG. 1, the socket type automatic welding device includes a sleeve tube 20 in which a plastic pipe 10 to be bonded is mounted and a heating wire 22 is embedded therein, and a heating wire 22 in the sleeve tube 20. The electric socket 24 for supplying power to the electric socket, the connector 32 coupled to the electric socket 24, and the power applied to the electric socket 24 according to the welding parameter are controlled and mounted to the sleeve tube 20. It consists of a fusion controller 40 for melting / bonding between the pipes. In addition, the fusion controller 40 is connected to the connector 32 by a conductive wire and includes a power supply device for applying a current to the heating wire. In addition, the electric socket 24 is provided with an electrode 26 connected to the heating wire 22.

In such an electric melting socket welding device, when the plastic pipes to be joined are inserted into both sleeve pipes 20 and the connector 32 is connected to the electric sockets 24, a current flows from the power supply to the hot wire of the sleeve pipe 20. Will flow. At this time, the fusion controller 40 heats the heating wire with a current or power amount of a temperature at which the plastic pipe can be fused.

However, in the case of the above-mentioned electrofusion socket fusion apparatus, the fusion parameters such as heating temperature and time of the heating wire must be accurately adjusted according to the size of the plastic pipe. If not, bad pipe joints will occur.

Therefore, in order to prevent this, in the related art, an identification resistor corresponding to the type of the electric socket 24 is embedded in the hot wire so that the welding controller 40 can automatically recognize the welding parameter according to the size of the plastic pipe. A method of recognizing a socket type by detecting a value has been proposed. That is, this method performs the welding operation by adjusting the power amount of the heating wire according to the identification resistance value according to the type of the socket.

However, this method of recognizing the socket of the resistance insertion method deteriorates the reliability of the welding process because the specification of the welding parameter may be incorrect when the resistance value is inaccurate, and data on the material, size, and manufacturer of the pipe are not input. Do not.

Besides the above-described resistance insertion method, other socket recognition methods include a magnetic card or a microchip embedded method.

However, in the case of such a socket recognition device, despite the advantage that the socket recognition method is accurate, it is difficult to apply it directly to the product because the equipment related to the magnetic card or the microchip is expensive.

An object of the present invention is to manufacture a recognition device consisting of a plurality of grooves of the concave-convex shape in the power socket or the sleeve of the sleeve tube in order to solve the problems of the prior art as described above, and the fusion parameter by the contact of the switch by the height difference of the unevenness It is to provide a socket type automatic fusion device that can recognize the type and manufacturer of the socket accurately and at the same time lower the unit cost of the product.

Another object of the present invention is to provide a recognition device having a metal surface electrode in a sleeve tube, and to provide a coupling device having a metal electrode in electrical contact with the metal surface electrode of the recognition device, whereby the metal electrode contact state between the recognition device and the coupling device is provided. According to the present invention to provide a socket type automatic fusion device that can recognize the fusion parameters of the socket type and manufacturer.
