And a power supply unit (S) for supplying power to the heating wire (360).

In the present invention as described above, the hot wire 360 is composed of a plurality of hot wires arranged in the vertical direction. As shown in FIG. 1, in which a large block type SF is attached by the plurality of hot wires, And a plurality of styrofoams formed by a plurality of arranged heat lines 360 to form a thin thickness up and down.

In addition, the individual heat lines are connected in parallel in the power supply unit S to the parallel heaters. The detailed configuration of such a parallel configuration will be described later in detail. By this parallel configuration, even if one heat line is cut off by each power line having independent power lines, the other heat lines can be supplied without any abnormality .

And an individual thermal line parallel power supply unit 52 that receives power from the power supply unit S and supplies power to the heat lines through individual column selection units.

Particularly, the power supplied by the individual heat wire parallel power supply unit 52 for each of the individual heat wires is made of an AC power source.

That is, the individual thermal linearly connected power supply unit 52 is composed of an input coil and an output coil wound around the core and cores, respectively, and supplies power from the input coil side to the output coil side by the magnetic field.

Therefore, the magnetic field generated by the input side power source influences the output side coil through the core, thereby generating the AC power while generating the inductive power at the output side coil, and the output of the AC is supplied to the individual heat wires.

Since the separate heating wires are connected in parallel to each other while being supplied with such AC power, since the circuit configuration is independent even if other heating wires are disconnected, normal hot wires are continuously supplied with AC power, . ≪ / RTI > As a result, it is possible to cut the styrofoam stably, thereby achieving a high quality styrofoam cutting.

In the example of the accompanying drawings, a total of five heat lines are formed. The heat line 360 includes a first heat line 361, a second heat line 362, a third heat line 363, a fourth heat line 364, And the fifth heat line 365. The five heat lines will be described with reference to specific embodiments of the present invention. The configurations of the present invention can be applied to the same or similar similar configurations And will have action.

The first power line 511 and the second power line 362 are connected to both ends of the first heat line 361 and connected to both ends of the second power line 511 and the second heat line 362, A third power line 513 connected to both ends of the third heating line 363 and a power source connected to both ends of the fourth heating line 364 and a fourth power line And a fifth power line 515 connected to both ends of the fifth heat line 365 and supplied with power.

And a fifth power conversion / supply unit 525 for supplying AC power to the fifth heat line 365 through the fifth power line 515.

As described above, since the power supply and the power supply are separately provided for the individual heat lines, the power supply and the power supply can be supplied independently of each other. Therefore, even if one side of the hot- Are in a normal state so that they can be stably cut to provide a high-quality cut-off foam.

And a cutoff control unit 60 for controlling the power supply unit S to supply power to the drive motor 240 side.

The detailed configuration of the cutting control unit 60 includes a main controller 61 for discriminating the information received from the sensors of the cutting apparatus and controlling the members.

And a chain drive motor control unit 62 for controlling supply of power to the drive motor 240 for operating the transfer chain 230 to operate the drive motor 240 and the transfer chain 230, SF) at a predetermined distance and speed.

And a chain operation discriminating part 63 for receiving the rotation state of the transport chain 230 operated by the drive motor 240 from the chain rotation sensor 631 and discriminating the operation state of the transport chain 230 . Thus, it is determined whether or not the transport chain is operating normally.

And a main power supply control unit 64 for transmitting a control signal to the power supply unit S under the control of the main controller 61. [

In addition, the cutoff control unit 60 includes a first power line 511, a second power line 512, a third power line 513, a fourth power line 514, a fifth power line 515, An individual power supply discrimination unit (for discriminating the application of power to the first heat line 361, the second heat line 362, the third heat line 363, the fourth heat line 364, and the fifth heat line 365) 65).

The individual power source application discrimination unit 65 includes a first power source discrimination unit 651 connected to the first power source line 511 to discriminate application of power to the first heat source line 361, A second power discrimination unit 652 connected to the second heating line 362 to discriminate the application of power to the third heating line 363 and a third power line 513 connected to the second heating line 362, A fourth power source discrimination unit 654 connected to the third power source discrimination unit 653 and the fourth power source line 514 for discriminating application of the power to the fourth heat line 364 and a fifth power source line 515, And a fifth power discrimination unit 655 for discriminating the application of the power to the fifth heat line 365.

Thus, it is possible to judge whether or not the power supply is normally supplied to each of the individual heat lines, and whether or not the heat generation effect is achieved.

In addition, in a detailed configuration of the cutting control unit 60, a cutting edge SF (SF) is formed between the cutting initial position where the cutting sprout SF to be cut is started to be fed by the feed chain 230, And a cutting position judging section 66 for judging the position that is positioned.

That is, when the heating foil SF is conveyed by the operation of the transfer chain 230 in a state of being heated to a predetermined temperature by power supply to the heating wire 360, the heating coil 360 contacts with the heating wire 360 while passing through the heating wire 360, (SF) is cut by the conveying chain 230, and the styrofoam (SF) is cut in the horizontal direction to form a thin foil foam.

In this case, the feed distance of the static foam (SF) fed by the feed chain 230 may be calculated. Such a conveying distance is determined by a method of discriminating the conveying distance through the rotation number and rotation time of the driving motor 240, a method of discriminating from the reference position of the conveying chain 230 by the conveying distance of the conveying chain, A method of calculating the distance of travel by discriminating the position by the contact type of the terminal switch or the non-contact type sensor such as a laser or the like may be applied, and generally a technique of calculating the distance of travel may be applied .

Next, a heat ray that distinguishes the broken heat ray from the current flowing in the first heat ray 361, the second heat ray 362, the third heat ray 363, the fourth heat ray 364 and the fifth heat ray 365 is interrupted, And a disconnection discrimination unit 67. [

That is, whether individual heat lines are disconnected or not may be determined according to the current flow of the individual heat lines determined by the individual power source discrimination units of the individual power source application discrimination unit 65.

The term "disconnection" referred to in the present invention refers to a case where a physical disconnection occurs in which a power line connected to a physical hot line or a hot line is disconnected or a predetermined current is not applied as a hot line due to a circuit abnormality, And the case of electrical disconnection in case of failure. That is, a state in which the heat can not be generated in the individual hot wire and thus the steel foam can not be cut as heat is referred to as a single wire in the present invention. In this disconnection state, not only the styrofoam can not be cut off, but if the styrofoam is continuously fed in a state that the styrofoam is caught by a hot line which can not be cut, the other styrofoam may be damaged. It can be broken.

Therefore, the individual power supply discrimination unit 65 discriminates whether the power supply is physically or electrically disconnected.

In addition to this, the hot wire disconnection part 67 can be provided with any one of the first heat ray 361, the second heat ray 362, the third heat ray 363, the fourth heat ray 364 and the fifth heat ray 365 When it is determined that the hot wire is broken, the position information in the cutting state of the styrofoam (SF) determined by the cutting position determining unit 66 is received and the position where the styrofoam SF is located is detected at the cutting initial position A cutting end determination unit 68 for generating a cutting end signal for terminating cutting when a predetermined cutting end position has not elapsed by analyzing whether or not a predetermined cutting end position has elapsed from the cutting end position and transmitting the cut end signal to the main controller 61 .

The main controller 61 stops the operation of the transfer chain 230 by cutting off the power applied to the drive motor 240 through the chain drive motor control unit 62.

That is, when it is determined that one or more hot wires are disconnected by the hot-wire disconnection discriminating section 67, the position where the hot-rolled foam SF is fed in the disconnection is received from the cutting position discriminating section 66. The cut-off continuation determining unit 68, which has received the cut-out information and the cut-off position, performs the continuous cut-off process when the position transferred at the cut-off passes the predetermined position. On the other hand, A cutting end signal for stopping the cutting process is generated.

With respect to this predetermined position, it may be determined that the residual chopsticks remaining in the broken hot wire are likely to be cut off.

That is, when the transfer of the styrofoam is stopped by the disconnection discrimination of one heat line during the cutting process, there is a latent heat even if the heat is continuously generated in the normal heat line or the power supply is interrupted. As a result, Excessive heat may damage the portion of the styrofoam, which may be unusable as a sheet of styrofoam, so that it may cause disadvantages such as disposing not only the styrofoam where the broken line is located but also other portions.

However, in the case where there is only a small amount of remaining styrofoam parts to be cut off, it is possible to continuously supply the remaining heat to the heat while continuing to transfer the styrofoam, The cutting is normally performed on the styrofoam in which the other normal hot wire is located.

In this case, only the top and bottom side screoforms of the contact area where the broken wire is contacted are removed, and the styrofoam plates where the remaining normal hot spots are located are in good condition, so that they can be treated as good quality products.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The technical idea of the present invention should not be construed as being limited.
