It relates to an inspection and supply device for heating rods for ondol heating that enables supply to and recovery of defective products.

Heating using electricity is a preferred heating method due to its comfort and relatively low operating and installation costs, and as an eco-friendly heating method, it has recently been in the spotlight as a heating device that is embedded in the floor or wall of a building.

In this way, the heating rod (heater) for ondol heating, which is embedded in the floor or wall, has an exterior made of stainless steel and is manufactured by filling the interior with magnesium oxide, an insulating material. The lifespan, strength, and insulation of the heating rod, etc. It is recognized as a long-lasting product.

Such heating rods are manufactured in lengths of 1.0M, 1.5M, 2.0M, 2.5M, 3M, 4M, etc., and depending on each construction space and method, the constructor connects heating rods with the above lengths in series or parallel. Construction is done.

In this way, in heating electric equipment, the heating rod is generally made depending on the manual work of the worker, and if there is a problem with the heating rod used in this work, many problems such as the need for re-construction arise, so this rework is not possible in advance. In order to solve problems such as these, the inspection process for the heating rod is essential.

And in order to remove foreign substances on the outer surface of the heating rod supplied to the axial pipe device 200, foreign matter is installed on the path where the heating rod progresses to the axial pipe device 200 in front of the heating rod inlet 210 of the axial pipe device 200. It includes a removal unit 160, which includes a brush unit 161 that contacts the left and right, upper and lower surfaces of the heating rod to remove foreign substances, and an air unit that supplies air toward the heating rod to remove foreign substances ( 162).

And the resistance test unit 122 is transferred in the direction of the heating rod, the sensor 123 is brought into contact with the heating rod, and the resistance test unit 122 is controlled to perform a resistance and earth leakage test, and the value of the sensor 123 is read to determine the resistance, Generates an earth leakage test result, determines the length and bending of the heating rod according to the detection signal input from the contact sensor 124, and determines the length and bending of the heating rod according to the test results of the resistance test control unit 152 and the length and bending test unit 153.

And the control unit 150 determines the time to supply the heating rod to the shaft pipe 200 by predicting the time taken for the shaft pipe process of the shaft pipe 200 according to the length of the detected heating rod, and accordingly, the heating rod transfer unit ( 130) can be controlled to supply the heating rod to the axial pipe 200.

The control unit 150 includes information required for the shaft pipe process of the shaft pipe device 200 according to the length of the heating rod, and uses the length information of the heating rod detected in the process of determining the length and bending of the heating rod to perform the shaft pipe process of the heating rod. Predict the time it takes and decide when to supply the heating rod to the axial tube (200).

Since the shaft pipe process consists of filling and compressing insulation in a heating rod, the time for which the shaft pipe process proceeds in the shaft pipe machine 200 is bound to vary depending on the length of the heating rod.

In other words, if the length of the heating rod is long, it takes longer for the heating rod to proceed through the shaft pipe process through the shaft pipe machine 200.

Therefore, the control unit 150 has information on the time required for the shaft pipe process of the heating rod according to the standard length of the heating rod, and refers to the time required for the shaft pipe process of the heating rod according to the detected length of the heating rod supplied prior to the shaft pipe device 200. The timing of supply of the heating rod is determined by predicting the shaft pipe process time of the previously supplied heating rod.

For example, if the length of the heating rod on which the shaft pipe process is currently in progress is 1M, the current shaft pipe process time is predicted by referring to the shaft pipe process time for the 1M-long heating rod, and the time when the shaft pipe process for the preceding heating rod is completed. The heating rod is put into the shaft pipe machine 200, and if the length of the heating rod on which the shaft pipe process is currently in progress is 4M, the shaft pipe process time currently in progress is predicted by referring to the shaft pipe process time for the 4M long heating rod, At the point when the preceding heating rod axial pipe process is completed, the heating rod is put into the axial pipe machine 200.

In this way, the shaft tube process time increases depending on the length of the heating rod, and therefore the waiting time for injecting the heating rod into the shaft pipe device 200 increases.

In the present invention's heating rod inspection and supply device for ondol heating constructed as described above, the inspection process of the heating rod supplied to the axial pipe 200 is described as follows.

The heating rod supply unit 110 storage box 111 contains a heating rod connected to an electrode.

As shown in FIGS. 2 to 6, the heating rod stored in the storage box 111 is connected to the first holder 112, the separation piston 113, the first piston 115, and the second piston 116. It passes through the second holder 114 and is seated on the standby block 121 as shown in FIG. 6.

And the control unit 150 controls the heating rod transfer unit 130 to pick up and fix the heating rod seated on the standby block 121 with the jig 131.

Afterwards, the control unit 150 slides the resistance test unit 122 in the direction of the heating rod as shown in FIG. 7 to bring the resistance test unit 122 into contact with the electrode of the heating rod.

The control unit 150 performs resistance and electric leakage tests and determines the resistance value and presence of electric leakage by judging the value read from the sensor 123.

When the resistance and earth leakage tests are completed, the control unit 150 moves the resistance test unit 122 backwards, separates it from the electrode of the heating rod, and moves it to its original position, as shown in FIG. 8.

Meanwhile, the control unit 150 extracts the length information of the heating rod from the signal input from the contact sensor 124, determines whether the length is normal by comparing it with the standard length information of the heating rod, and can also detect the bending of the heating rod.

In the heating rod inspection unit 120, a plurality of contact sensors 124 are installed in accordance with the heating rod lengths of 1.0M, 1.5M, 2.0M, 2.5M, 3M, and 4M to contact the heating rod mounted on the waiting block 121. They are arranged along the standby block 121 at positions and intervals, so that the length of the heating rod can be detected according to the detection signal from the contact sensor 124, and the bending can be detected according to the presence or absence of an input signal from the contact sensor 124. can do.

Here, the length of the heating rod can be detected by using information on both ends of the contact sensor 124 where the detection signal is input. According to an embodiment of the present invention, the moving distance of the resistance test unit 122 and the installation of the contact sensor 124 Using the location information and the detection signal from the contact sensor 124, the length of the heating rod can be detected.

Additionally, the control unit 150 may determine that the heating rod is bent when there is no contact detection signal from the contact sensor 124 because the bent portion of the heating rod may not be in contact with the contact sensor 124.

As described above, when the length and bending test for the heating rod is completed, the control unit 150 controls the heating rod transfer unit 130 according to the resistance test, earth leakage test, and length and bending test results to transfer the heating rod to the shaft tube 200. Alternatively, the heating rod is transferred to the defective product recovery unit 140.

If the heating rod is defective, such as resistance, short circuit, length, or bending, as shown in FIG. 8, it is transferred to the defective product recovery unit 140 and the defective heating rod is stored in the defective product recovery unit 140. In the case of a good product, as shown in FIG. 9 As shown, it is inserted into the foreign matter removal unit 160 and seated at the injection standby position of the axial pipe 200 of the standby block 121.

As described above, the control unit 150 transfers the heating rod into the foreign matter removal unit 160, operates the brush unit 161 and the air unit 162 to remove foreign substances from the outer surface of the heating rod, and removes foreign substances from the external surface of the heating rod. While the heating rod enters the axial pipe 200, the brush unit 161 and the air unit 162 are operated to remove foreign substances from the heating rod and allow it to enter the axial pipe 200.

Meanwhile, the shaft pipe process performed in the shaft pipe machine 200 is a work process of filling magnesium oxide, an insulating material, into the heating rod and compressing the heating rod to remove the air inside it. The time taken for the shaft pipe process may vary depending on the length of the heating rod. there is.

If the heating rod is supplied into the axial tube machine 200 while the axial tube process for the heating rod is in progress within the axial tube machine 200, a problem may occur in the axial tube machine 200.

Therefore, the control unit 150 predicts the time taken according to the length of the heating rod, calculates the timing of supplying the heating element to the axial pipe machine 200, and transfers the heating rod to the axial pipe machine 200 accordingly.

That is, the time taken for the shaft tube process is predicted according to the length of the heating rod supplied to the shaft pipe machine 200 and the shaft pipe process proceeds, and the heating rod is supplied to the shaft tube machine 200 at the time the shaft tube process is completed.

The control unit 150 controls the heating rod transfer unit 130 according to the time at which the heating rod is supplied to the shaft pipe machine 200 as described above and transfers the heating rod to the shaft pipe machine 200 to the heating rod injection port 210. Insert it with

Afterwards, when the heating rod is further pushed and transported inside the shaft pipe 200, the heating rod inside is advanced on the roller 220 of the shaft pipe 200. At this time, the control unit 150 detects the load in the load sensing unit 132. The detected load value is read and compared with the standard load value to determine whether the shape of the heating rod is abnormal.

The heating rod transfer unit 130 inserts the heating rod through the heating rod inlet 210 of the axial pipe 200, and after being bitten by the roller unit 220 of the axial pipe 200, the heating rod is moved by the roller unit 220. The heating rod is held by the jig 131 to the transfer position and the heating rod is pushed in. At this time, the heating rod transfer unit 130 is loaded according to the rotation of the roller unit 220, and the normal heating rod is connected to the axial pipe (200). ) is used to determine whether there is an abnormality by comparing it with the load standard value applied when it is transported through normal operation.

This is to determine the bending that was not checked in the bending test of the control unit 150 and other abnormalities in the heating rod. If there is another abnormality such as shape bending, a load is generated as it is supplied to the axial pipe 200 and pushed in, thereby causing the problem. The purpose is to determine whether there is an abnormality using the load information. If the load occurs, it may occur even if there is a problem with the shaft pipe 200. If it is determined that there is an abnormality, notification information is provided through the inspection notification unit 170 to the manager. Have someone perform an inspection on the axial pipe 200 or the relevant heating rod.

According to the present invention, the external shape of the heating rod, such as resistance, electrical leakage, length, and bending, is inspected to select and distinguish defective heating rods, and only good heating rods can be supplied to the shaft tube 200, It can provide a smooth production process environment and provide a heating rod inspection device that can prevent defects in the heating rod shaft pipe process.
