DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fusion joint in which ends of opposed pipe members are fitted to each other so as to abut each other, and are fused. More specifically, product information is provided on the surface of the fusion joint. The present invention relates to a bar code printer device of a fusion joint with a bar code for printing or attaching a bar code.

[0002]

2. Description of the Related Art A fusion joint for connecting a pipe member such as a polyethylene pipe (water pipe, gas pipe, etc.) has a heating coil therein. Heat is generated by energizing the heating coil, and the heat fuses the pipe members.

[0003] The degree of fusion of the pipe member is determined by the amount of heat generated by the heating coil, and the amount of heat generated is determined by the resistance value of the heating coil and the energizing time. Conventionally, as a means for determining the energization time, a plurality of types (for example, 20 types) of standard resistance values of the heating coil are set according to the type and diameter of the fusion joint, and the heating coil of the fusion joint of a certain type is set. Are manufactured so that the resistance value of the above-mentioned resistance falls within an error range (for example, ± 3%) of the standard resistance value set correspondingly, and the fusion joint is manufactured.

At the manufacturing stage, a label printed by converting information (shape, type, diameter, standard resistance value, etc.) of the fusion joint into a bar code in advance is attached to the fusion joint during the production. ing. This label is printed in advance in the office, etc. for the required number of varieties of the type to be manufactured on that day, and the finished label is manually pasted to the fusion joint by the manufacturer in the final process of manufacture. I have.

On the other hand, the fusion spliced joint thus manufactured is then sent to a product inspection step, where various product inspections are performed. One of the product inspections is a resistance value inspection. Conventionally, the resistance value inspection is performed as follows.

That is, first, the inspector inputs the standard resistance value of the fusion joint to be inspected to the inspection machine by manual input. Here, the input of the standard resistance value is performed by an inspector visually confirming the fusion joint to be inspected, judging the type and size of the fusion joint, and determining the standard value corresponding to the applicable type and size. The resistance value is checked and input, for example, in a list.

Next, the resistance value of the heating coil of the fusion joint is measured by a resistance measuring device (such as a tester) and input to an inspection machine. The inspection device compares the manually input standard resistance value with the actually measured resistance value measured by the resistance measuring instrument, and determines whether the actually measured resistance value is within an error range of the standard resistance value (for example, ± 3%). To inspect. Then, if the measured resistance value is within the error range of the standard resistance value, it is determined to be acceptable, and if the measured resistance value is not within the error range of the standard resistance value, it is determined to be unacceptable. Such an inspection is performed on all manufactured fusion joints.

Is manufactured, there is a problem that a label printed with product information of one kind may be attached to a fusion joint of another kind, which may cause an erroneous attachment. In addition, since the sticking is performed manually by the manufacturing worker, there is a problem that the sticking method is not constant, and the sticking or peeling off occurs.

Further, when the product is small and there is no space for attaching a label, there is a problem that a tag or the like for attaching a label is required. The present invention has been devised to solve such problems, and its purpose is to print a bar code, which is product information, directly on the fusion joint, or to automate the operation of attaching a label, An object of the present invention is to provide a bar code printer device of a fusion spliced joint with a bar code, which eliminates sticking errors.
