Accordingly, an overload may occur in the mold depending on the load of the working material used in the press apparatus, and a system for managing the load is required to prevent the overload.

Conventionally, a press load management system for mold overload protection includes a strain gauge sensor for sensing a torn value mounted on an UPRIGHT of a press device, and a dedicated controller for correcting and managing the torn value. In such a press load management system, a tincture value detected from a strain gauge attached to the upright at the time of starting the press apparatus is inputted to the dedicated controller and displayed. At this time, the operator performs TRYOUT of the mold with reference to the displayed TONY value and refers to the production. Further, in the conventional press load management system, the tread value is initialized to "0 " at the time of restarting the press apparatus, and the above processes are repeated at the time of press forming.

However, the conventional press load management system for protecting the overload of the mold has a problem that it is insufficient to substantially protect the mold by displaying only the tornee value in the typical controller, and it is insufficient to protect the press apparatus due to the mold offset. Further, there is a problem in that it is difficult for the worker to read the non-molded product after molding the product since the worker must keep a close watch on the torn paper value. That is, the conventional press load management system for protecting the mold overload has a problem that the mold or the press apparatus can not be protected separately except for the function of displaying the torn paper value.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which those skilled in the art can readily implement the present invention.

FIG. 1 is a schematic view of a press load management system for protecting a mold overload according to an embodiment of the present invention. FIG. 2 is a block diagram of a press load management system for protecting a mold overload according to an exemplary embodiment of the present invention. FIG. 3 is a graph for explaining the operation of the HMI and the PLC control unit of FIG. 1, and FIG. 4 is a flowchart schematically illustrating the operation of the press load management system for protecting the mold overload of FIG.

Referring to FIG. 1, a press load management system for protecting a mold overload according to an exemplary embodiment of the present invention includes a sensor unit 1 provided in a press apparatus for molding a mold, A PLC input unit 3 to which a maximum value and a minimum value are inputted for each of the molds, and a controller 2 that receives a tony value from the dedicated controller 2 and reads the tony value from the dedicated controller 2 And a HMI and PLC control unit 4 for comparing the maximum value and the minimum value inputted to the PLC input unit 3 with the read tony value and controlling the driving of the press apparatus according to the comparison result.

The sensor unit 1 may include at least one strain gauge sensor. The strain gauge sensor is a sensor for detecting mechanical fine strain by an electric signal and is used by being adhered to a plurality of surfaces of a press apparatus. Such a strain gauge sensor measures a strain by applying a microscopic change occurring on the surface of the press apparatus, that is, a physical phenomenon in which the resistance value changes.

The maximum value input to the PLC input unit 3 may be compared with the Tony value extracted from all molding sections of the press apparatus. Accordingly, when the TONY value taken out of the maximum value inputted to the PLC input unit 3 is large, the HMI and PLC control unit 4 can stop the press apparatus.

The minimum value input to the PLC input unit 3 may be compared with a torn paper value taken out in a section where the press apparatus (that is, the press angle (PRESS ANGLE) or the press crank angle) is 250 degrees or more. Accordingly, the HMI and PLC control unit 4 can stop the press apparatus at the top dead center when the tincture value extracted from the minimum input to the PLC input unit 3 is small.

The HMI and the PLC control unit 4 determine whether the input value and the control characteristic curve, which are detected by the sensor unit 1 When the tornee value is located at the first point, the press apparatus is immediately stopped and the corresponding message is outputted through the display unit 5. [ At this time, the sensor unit 1 senses the entire interval. When the tincture value sensed by the sensor unit 1 is positioned at two points in the non-forming period (250 degrees), the HMI and PLC control unit 4 stops the press apparatus at the top dead center, And the corresponding message can be outputted through the display unit 5. That is, the HMI and PLC control unit 4 stops the press unit in a full cycle when the tincture value detected by the sensor unit 1 is less than the minimum value.

The HMI and PLC control unit 4 may further include an alarm display unit (not shown) for outputting an alarm signal to the outside. When the tincture value extracted from the minimum value input to the PLC input unit 3 is small, the alarm display unit stops the press apparatus at the top dead center under the control of the HMI and PLC control unit 4 and outputs an alarm signal to the outside .

The HMI and PLC control unit 4 may further include a display unit 5 that can display the maximum value and the minimum value individually. The display unit 5 may include a plurality of unit display units 5c, 5d, 5e, and 5f corresponding to respective dies, and may include an entire display unit 5b that expresses a total TONY value.

Meanwhile, the HMI and PLC control unit 4 are provided with a PLC control program and a designing HMI program for PLC control and HMI design for load and mold overload management of the press device, and the respective programs execute the above- Can be implemented.

The operation of the press load management system for protecting the mold overload according to the present invention will be described with reference to FIG. 4. First, the operator selects either the entire or individual management of the mold in the HMI, stores the maximum value or the minimum value , The start of the press apparatus can be instructed. Then, if the maximum value and the minimum value are compared with the extracted TONY value, if it is larger than the maximum value, an urgent stop command for the press apparatus is provided. If the minimum value is smaller than the minimum value, Thereby protecting the press apparatus and the mold. That is, it is determined whether or not the extracted tony value (i.e., PEAK tone) deviates from the maximum value (i.e., MAX tone), whether or not the press angle is 250 degrees or more and the extracted Tony value is less than the minimum value Emergency stop command or top dead center stop command can be commanded.

Therefore, according to the press load management system for protecting the mold overload according to the present invention, since the torn value is managed for each mold, even when unexpected situations such as equipment abnormality, mold abnormality, material abnormality, foreign matter input, As a result of the change, the press apparatus is stopped at the emergency position or the top dead point, so that it is possible to protect the mold from being protected from the mold, and to protect the press apparatus from the load.
