Referring to FIG. 6, the controller 400 according to the embodiment of the present invention may include a memory unit 410, a receiver 420, a data converter 430, a data processor 440, an ultrasonic driver 450, and a motor driver. 460. Additionally, the controller 400 according to the embodiment of the present invention may further include a screen output unit 470.

The memory unit 410 stores setting load data for the target object.

In the preferred embodiment of the present invention, the receiving unit 420 receives the processing load input from the input unit 490. The data communication between the input unit 490 and the receiving unit 420 is a serial communication method through a cable. Or it may be made by a wireless communication method.

As such, the processing load received through the receiver 420 is converted into digital data through the data converter 430.

Hereinafter, the ultrasonic operation and the Z-axis operation state that is a feature of the present invention will be described.

Figure 7 is a flow chart for explaining a paper-type punching method using ultrasonic waves using a paper mill other milling device according to an embodiment of the present invention.

Before explaining the operating state of the Z-axis transfer unit 130 and the booster cylinder 140 with reference to Figures 1 to 7, the description according to the operating state to be described later the position of the pita ball by positioning the transfer table 110 After being mounted at the punching position, through the receiving unit 420, a processing load signal corresponding to the pressing pressure applied to the punched object at the current punching knife 160, the distance between the punched knife and the punched object, the pressing speed, the thickness of the punched object, and the like On the premise of receiving and transmitting the received processing rod signal to the controller 400. In this embodiment, it is assumed that the machining rod signal includes the pressing pressure applied to the workpiece by the punching knife.

1 to 7, the controller 400 receives a processing load signal through the receiving unit 420 (step S10). The received processing rod signal may include information such as a pressing pressure, a distance between the punching knife and the workpiece, a pressing speed, a thickness of the workpiece, and the like, and are converted into digital data by the data converter 430 to process the processing load data. Is generated.

Subsequently, the processing load data generated by the data converter 430 is compared with the setting load data stored in the memory unit 410 (step S20). The set load data is optimal data on the perforation conditions of the target object to be measured measured by the experiment. The setting load data is set by the operator according to the object to be punched and the drilling conditions. In the present embodiment, the set load data may include pressing pressure information (or pressing force) applied to the workpiece by the punching knife, or may include thickness information of the workpiece.

If the machining rod data and the setting rod data are checked to be the same in step S20, the current state between the perforated knife and the workpiece is maintained, and the stop of the servo motor 120 and the stop of the ultrasonic wave are maintained (step S30). This is because the perforation operation can be smoothly performed on the object to be transported even under the already set perforation conditions.

However, if the comparison result is not the same to drive the Z-axis drive motor included in the Z-axis transfer unit 130 to elevate the Z-axis transfer unit 130. This is because the perforation operation cannot be performed normally even with the perforation conditions already set. For example, the gap between the currently set punching knife and the punched object or the pressing force sufficient to drill the punched object normally may not be set.

That is, if it is checked in step S20 that the processing load data and the setting load data are not the same, it is checked whether the processing load data is larger than the setting load data (step S40).

On the other hand, if it is checked in step S40 that the machining rod data is larger than the set load data, the Z-axis driving motor is driven to raise the Z-axis feeding unit 130, and the ultrasonic drive and the cylinder are operated (step S50). That is, according to the driving signal input from the controller 400, the Z-axis transfer unit 130 is raised and the ultrasonic driving is operated. For example, if the pressing force corresponding to the set load data is 100 kg and the pressing force corresponding to the processing load data is 150 kg, the perforation operation is not performed smoothly. However, according to the present invention, by performing the ultrasonic drive, it is possible to smoothly perform the punching operation of forming a hole in the workpiece with a smaller force.

On the other hand, if it is checked in step S40 that the machining rod data is smaller than the set load data, the Z-axis feeder 130 is lowered (step S60). At this time, the driving motor of the Z-axis transfer unit 130 is driven to rotate in the forward direction according to the drive signal input from the controller 400, for example, the Z-axis transfer unit 130 is lowered.

As such, when the processing rod data and the setting rod data are checked to be different from each other, the Z-axis feeder 130 and the ultrasonic drive unit are driven up and down by the driving of the motor according to the drive signal of the controller 400, and the ultrasonic drive is performed, thereby making the pita Drill by adjusting the separation distance between the punching knife and the punching object so as to punch with the optimal punching force for the tribute.

Accordingly, the other paper mill for punching paper according to the embodiment of the present invention is punched while the lifting and ultrasonic operation of the Z-axis transfer unit 130 is driven or maintained in the current punching state according to the drilling conditions.

Following step S30 or after step S50, or after step S60, it is checked whether perforation is completed (step S70). If it is checked in step S70 that the perforation is completed, the perforation work is terminated. If the perforation is not completed, the booster cylinder 140 is artificially re-entered to step S10 by a continuous cycle until the end of the work artificially through the aforementioned steps. Repeatedly performs the punching operation.

Therefore, the paper mill punching plant according to an embodiment of the present invention to maintain the optimum processing rod for the pitting object by adjusting the separation distance between the punching knife and the pitting object through the processing rod applied to the pitting object, ultrasonic drive By perforation, the perforation speed and the product quality can be expected.

8 is a graph illustrating the relationship between the number of punches and the pressing pressure by the paper puncher and the general puncher according to the present invention.

Referring to FIG. 8, it can be seen that the other paper mills for punching paper according to the present invention are also punched with a relatively low pressing pressure (or pressing force) for the same number of punches as compared to a general punching device.

In addition, when the perforated sheet number reaches the threshold, the general perforated factory value is no longer perforated smoothly. However, the paper mill punching mill according to the present invention can be seen that the punching operation is performed smoothly even if the number of punching increases compared to the general punching device.

Therefore, the punching mill for punching papers according to the present invention can form a hole in a larger number of punching sheets even if the same pressing force is applied, and a hole can be formed in the workpiece with a smaller pressing pressure even with the same punching sheet. have.

Although described above with reference to the embodiments, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below. I can understand.

As described above, according to the present invention, the Z-axis feeder equipped with a perforated knife is driven up and down, and the perforation operation is performed in a stable state with respect to the perforated object by perforating the perforated object in an optimal perforated state by the operation of ultrasonic waves. As a result, product defects are relatively less than that of a general punching device, and the burrs on the surface of the product can be obtained clean, and more importantly, productivity improvement can be obtained.

In addition, as the ultra-precise position control is possible by the data memorized by the automatic supply of the perforated product, the precision of the perforation in the minimum error range can be improved in the minimum error range. In particular, by outputting the information about the current punching state through the screen output, the operator can check and check the punching status of the work in progress at any time, and can visually check the punching status for the target object In addition, it is possible to maximize the efficiency for drilling by changing the drilling conditions to the optimum state.

In addition, since the paper mill punching machine according to the present invention uses ultrasonic waves, it is possible to form holes in the number of punches more than the general punching device even with the same pressing force, even with the same number of punches Also, a hole can be formed in the workpiece. Accordingly, the work time can be shortened and the power consumption can be reduced as compared with a general punching device.
