First, referring to FIGS. 3 and 4, the drying means 400 of the present invention includes a support 410, a casing 420, and a heating element 430.

The support 410 is configured to be bent up and down and left and right to immediately respond to the changing angle of the wire 310 released from the wire spool 300 due to the operation of the wire supply unit 200 described above, A first support 412 and the first support 412, one end of which is rotatably coupled in an up and down direction by a support shaft 262 on one side of the wire feeder 200, and is elastically supported by an elastic member 416. The second end of the hinge 415 is bent in the lateral direction in the axial direction and is configured to include a second support 413 formed with a coupling portion 414 for mounting the casing 420 on the lower side.

The casing 420 is mounted on the support portion 410, preferably the coupling portion 414 of the second support 413, and is bent in the same direction as the bending direction of the support 410, thereby feeding the wire 310. Corresponding to the insert portion 422 is inserted into the wire 310 and the discharge portion 424 is formed are respectively formed. At this time, the insertion part 422 and the discharge part 424 are coupled to the guide tube 426 having flexibility so as to minimize the bending and friction of the insertion and discharge wire 310, respectively. That is, the guide tube 426 is made of a material having elasticity, but implemented as a shape of a coil spring without a gap to have flexibility and at the same time reduce the contact area with the wire 310 to minimize friction.

The heating element 430 is mounted inside the casing 420 to form a drying passage 432 connecting the insertion portion 422 and the discharge portion 424 therein so that the wire 310 is inserted into the insertion portion 422. And to allow insertion and discharge through the discharge portion 424, it is configured to evaporate and remove the moisture contained in the surface of the wire 310 passing through the drying passage 432 by the exothermic action through the electrical connection. Of course, although the electrical connection of the heating element 430 is not shown, it may generate heat by receiving power from the outside, but the electric power is supplied to the wire feeder B through its own power supplied for the operating power of the feeding motor 230. In this case, the electrical connection is provided with a control unit, not shown, in a range of about 40 to 50 degrees, which is a temperature at which a heating element 430 is set, for example, a temperature enough to dry the wire 310. It is an electrical connection that can be maintained, and this temperature range can be adjusted as needed.

Drying means 400 configured as described above is coupled as shown in FIG.

That is, the support 410, that is, one end of the first support 412 is rotatably coupled up and down via the support shaft 262, and the support shaft 262 is a wire feeder 200, preferably a bracket. Although it may be provided separately on one side of 210, this may cause the complexity of the device, it would be preferable to use a support shaft 262 for mounting the guide roller 260. At this time, the support shaft 262 is mounted to the elastic member 416 together, one end of which is connected to support the first support 412 and the other end is connected to the bracket 210 of the wire feeder 200 to the first The support 412 is coupled to have an elastic force. Then, the second support 413 is coupled to the hinge 415 to the first support 412 by the axis to be bent to the left and right, and here it is not shown but the casing 420 having a heating element 430 therein By being fixed to the coupling part 414 of the second support 413, the coupling is completed on one side of the wire feeding part 200.

On the other hand, the coupling of the first support 412 to the support shaft 262 is mounted on the guide roller 260 means that it can be used as it is without changing the wire feeding device (B) already known and used It will be economical in terms of cost. However, it is clear that if the use of the support shaft 262 of the guide roller 260 is difficult, it may be provided by forming a separate support shaft.

The combined support 410 is divided into first and second supports 412 and 413 to be bent up and down and left and right, so that the wire 310 wound around the wire spool 300 is not unwound at the same position. The angle is changed and released while repeatedly moving left and right by the width interval of 300), and the change in position generated as the wound thickness is gradually thinned will also be immediately responded to in the following description of the operation relationship.

"A" in Figure 6 is an enlarged perspective view of the detection means according to a preferred embodiment of the present invention, "I" is a conceptual diagram of the detection means, Figure 7 is a coupling relationship of the detection means according to a preferred embodiment of the present invention Is a schematic side view.

First, referring to “a” and “b” of FIG. 6, the detecting means 500 of the present invention includes a rotating body 510 having a detecting unit 512 on one side, and a detecting unit of the rotating body 510. 512) a sensor unit 520 for sensing the rotational speed and a controller 530 for receiving the value sensed by the sensor unit 520 and comparing and analyzing the consumed amount of the wire 310 in real time.

The detection unit 512 of the rotating body 510 is sufficient to be the same as the magnetic body that the sensor unit 520 can recognize, and the sensor unit 520 and the controller 530 are not shown but are connected through a wired controller. 530 receives the sensing value. The controller 530 that receives the sensing value, that is, the rotational speed of the detector 512, includes an operation unit 532 that converts the rotational speed in units of length, and a display unit 534 that allows the naked eye to check the calculated value when the calculation is performed. It further includes.

As shown in FIG. 7, the detecting means 500 configured as described above has the rotating roller 510 feeding the wire 310 by the rotation operation, that is, feeding the feed roller 240 shaft of the wire feeding part 200. Is coupled to and configured to rotate together, the sensor unit 520 is fixedly installed via the mounting plate 522 to the bracket 210 to be located on the lower side of the feed roller 240. And, although not shown, the controller 530 is satisfied where the operator can easily check with the naked eye, that is, installed on any one side of the frame 100 or the bracket 210.

In this state, when the feed roller 240 is rotated to feed the wire 310, the rotating body 510 axially coupled thereto is also rotated together. Then, the sensor unit 520 senses the rotational speed of the detection unit 512 provided in the rotating body 510, and the controller 530, which has received this, converts the sensed rotational speed into a unit of length and displays it. will be. Then, the operator can easily check the supply amount of the wire 310 through the display unit 534 of the controller 530.

Figure 8 is a schematic side view showing a state of use of the welding wire feeder having a composite function according to an embodiment of the present invention, "A" of Figure 9 is the use of the drying means according to an embodiment of the present invention Partial incision enlarged perspective view showing a state, "I" is a partial enlarged view showing the use state of the detection means, "A" of Figure 10 is a schematic side view showing the operating relationship of the drying means according to an embodiment of the present invention. "I" is a schematic plan view.

First, referring to Figure 8, the welding wire supply device (B) of the present invention is connected to the welding torch 700 and the cable 710 via a wire 310 is a welding material wound on the wire spool 300 Is fed to the welding torch 700. More specifically, this feeding preparation process, first, the wire 110 is wound on the shaft 110 provided on one side of the frame 100, the wire spool 300 is wound, and the wire 310 is partially unwound Penetrating into the casing 420 of the drying means 400 provided on one side of the feed unit 200 to be supported by the guide roller 260, the upper surface of the feed roller 240, preferably the feed roller 240 outer periphery At the same time it is placed in the groove 242 formed in the welding torch coupling portion 220 is set so that its end is located. Of course, before the wire 310 is placed on the upper surface of the feed roller 240, it is a matter of course that the adhesion roller 250 provided on the upper side thereof is provided in a state where the adhesion is released by the rotation of the adhesion bracket 252. When the wire 310 is positioned to the welding torch coupling unit 220 in this way, the contact roller 250, which has been released in close contact, rotates and fixes the contact bracket 252 so that the wire 310 is in close contact with the welding torch coupling unit. When the cable 710 is connected to the 220 is ready.

Here, referring to “a” of FIG. 9, the wire 310 is inserted into a guide tube 426 coupled to the casing 420 inserting portion 422 of the drying means 400, and a heating element provided therein. It can be seen that after passing through the drying passage 432 of 430 is discharged to the guide pipe 426 coupled to the discharge portion 424.

And, as shown in "b", the feed roller 240 is coupled to the rotating body 510, which is the detection means 500, the sensor unit 520 is provided on the lower side of the frame 100 on one side It can be seen that it is connected to the provided controller 530.

In this state, the power supply to the drying means 400 to heat the heating element 430, and after a while to operate the feed motor 230, which is the wire feeder 200, the feed roller 240 is axially coupled thereto When rotated, the wire 310 in close contact with the contact roller 250 is fed to the welding torch 700 through the inside of the cable 710, and the wire 310 to be supplied is a drying passage 432 of the heating element 430. When passing through), the moisture that may be contained due to the high temperature heat is removed by evaporation so that it is fed in a dry state. Accordingly, by lowering the welding failure rate that can be generated according to the moisture content of the wire 310 to improve the productivity as well as to minimize the occurrence of safety accidents such as electric shock to improve the work efficiency.

In addition, the sensor unit 520, which is the detection unit 500, senses the rotation speed through the detection unit 512 of the rotating body 510 provided in the feed roller 240 that is rotated when the wire 310 is fed. After receiving this, the controller 530 converts the unit by length to display the wire consumption in real time. For example, assuming that the length of the wire supplied at the time of one rotation of the detection unit 512 provided in the rotating body 510 is 10 cm, the controller 530 reduces the consumption amount by the rotation speed sensed by the sensor unit 520. Easily converted into units can be displayed in real time. Accordingly, the operator can immediately grasp the consumption of the wire 310, so that the replacement timing can be accurately taken, and the cost calculation and the amount of work can be calculated for the usage of the wire 310 relative to the welding area, thereby improving work efficiency. Will be. In this case, the controller may display the remaining amount in addition to displaying the wire consumption. In other words, assuming that the wire 310 wound on the wire spool 300 is wound for 10 meters, the remaining amount may also be displayed when the consumption is calculated.

On the other hand, the wire 310 wound on the wire 310 when feeding the wire 310 is not released on the same horizontal line, it is natural that the angle drawn into the drying means 400, that is, the casing 420 is to be changed.

That is, the wire 310 wound on the wire spool 300 as shown in "a" of FIG. 10 is fed due to the rotation of the feed roller 240 at the position shown by the first solid line, and thus the wire spool 300 gradually. As the wire 310 wound around is consumed, the angle is changed by the portion shown by the broken line. At this time, since the first support 412 is rotated counterclockwise through the support shaft 262 according to the drawn angle of the generated wire 310 to receive the angle immediately, the drawn wire 310 is bent or No bending occurs to ensure smooth supply. Then, when the wire 310 wound around the wire spool 300 is completed and the wire 310 is no longer inserted into the casing 420 to replace the new one, the first support 412 is an elastic member ( 416) is immediately restored to its original state by the elastic force to prepare for the next supply preparation process.

As described above, as the wire 310 is unwinded from the wire spool 300, the angle thereof is changed upward, but as shown in the "I", the wire 310 wound on the wire spool 300 may have a wire spool ( As shown by the broken line by the width interval of 300) it is released while the angle is repeatedly changed from side to side. At this time, since the second support 413 is bent to the left and right sides of the hinge 415, the angle is changed from side to side, so that the second support 413 immediately responds to the angle change of the wire 310 to be released. Smooth feeding is possible.

In particular, a flexible guide tube 426 is mounted to the insertion portion 422 and the discharge portion 424 of the casing 420 into which the wire 310 is inserted to support the wire 310. 310) It is possible to respond more actively to the change in the inlet angle is more smoothly the feeding operation.

In addition, since one side of the frame 100 is provided with a lighting 600 installed by the bent connecting rod 610 can be appropriately placed in the place necessary for welding work to implement the lighting does not need to install a separate lighting It will improve convenience.
