[Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing the entire structure of a foot of a press molding machine (hereinafter abbreviated as "foot") according to an embodiment of the present invention. This foot base is a bending material placed on the mold for the pressure forming machine in a direction perpendicular to the ram (also referred to as "slider"), and is placed in a horizontal direction by the collision axis. The lower part is fixed with a ram of a stamping die, and is moved downward to apply a bending process, and is used to output various necessary instructions to the body of the pressure forming machine. The foot base is constituted by the base 1 body, the bracket 3, the seat box 5, and the like as shown in Fig. 1 . The base body 1 is a floor surface or the like on the front side of the pressure forming base body, and is disposed opposite to the pressure forming base body, and has a substantially box shape as a whole. The base body 1' has at least a sufficient capacity to accommodate both the operator's feet and the various mechanisms necessary; the front portion is such that at least the operator's feet are free to enter and exit, and the opening portion 7 is formed entirely. The inner space of the base body 1 is partitioned left and right by a partitioning plate 9 extending from the opening portion 7 to the entire rear surface of the inner space. The right internal space 1 1 of the base body 1 partitioned by the partition plate 9 is provided with an operation foot pedal (also referred to as a "down pedal" for performing a depression operation when the ram is lowered. The same) 1 3. Operating the pedal -9- 201139008 1 3 'Only when the operator steps on it, the ram is made. When the operator stops the stepping of the operating pedal 1 3, the collision stops and the movement stops. At the stop position. In the case of the operator, when the operator stops the pedaling until a certain period of time elapses (for example, before the vehicle is depressed again, the first descending motion is temporarily stopped. The pedals 13 are operated, for example, for the purpose of performing a new bending, respectively. The fixed stamping die is positioned, or the so-called setting of the table positioning tool (hereinafter referred to as "lower mold setting") is performed in the so-called micro-input mode. The operation pedal is separately fixed in the above setting operation. In the trial operation of the stamping die and the new bending process, in the single-input mode, the stepping operation is also performed. In the one-stroke mode of the so-called reverse production processing operation of the running pedal device In addition to the operation of the footboard 13 , the right inner space panel 9 is provided with a switch for causing the collision formed by the stepping operation pedal 13 to be in an effective state (hereinafter, this embodiment) In the mode, the switch is activated.) 15. This intentionally activates the switch 15 to be operated by the foot (right foot) before the operation of the foot pedal 13 is performed. The foot pedal 13 is set from the inactive state to the active state. In other words, when the operator calls the setting operation, or the so-called trial processing operation, or the so-called work industry, the switch 15 must be intentionally activated to perform the lowering operation in advance; When turning the pedals for about 13 seconds, the hammer is re-opened, and in the fixed mold mold industry, it will be at 1 3, which is used to make the mold, so-called 1 3, and the so-called safety sheet 1 The operation of lowering the separation hammer is indicated as "the operator performs the stepping operation of the manufacturer itself and performs the above-mentioned repeated production plus ON operation. -10- 201139008 For the intentional activation of the switch 15, it will be described later. The left internal space 17 of the partition base 1 is provided with a raised footrest 19 that performs a depression operation when the ram is raised. The pedal 19 is raised, and when the operator steps on it, the collision occurs. The hammer starts the ascending motion, and even if the operator stops the stepping of the stepping pedal 19, the hammer does not stop the lifting operation until it reaches a specific position (that is, the upper limit stop position). If it is composed of a round pipe, the base end side is vertically supported by the base body 1, and the upper end side is fixedly fixed with a box-shaped seat box 5. The inside of the bracket 3, for example, various lines such as a signal line or a power supply line are wired. The box 5 is provided with an LED 23 or various switches 35. The LED 23 is a pedal effective lamp as shown in Fig. 2. Fig. 2 is a diagram showing a control system of the pressure forming machine in one embodiment of the present invention. The control system includes the data display unit 29 included in the operation panel 27, the data input unit 31, and the foot holder 33 (shown in Fig. 1) as shown in Fig. 2; The emergency stop switch 3 5 'runs the foot pedal 1 3 , the raised foot pedal 丨 9 , the intentional start switch 15 , and the foot pedal effective lamp 2 3 . The control system described above includes the control unit 37, the servo amplifier 39', and the ram drive unit 41 in addition to the above-described respective units. The control device 3 7 ' includes a calculation unit 43 , a data storage unit 4 5 'operation preparation processing unit 47 , an abnormality detection unit 49 , an abnormality processing unit 5 1 , a hammer operation command unit 5 3 , and a BS (back gear). The operation command unit 55, the input processing unit -11 - 201139008 5 7 , and the output processing unit 59. The ram drive unit 141 includes a mechanically coupled ball screw 63, and is screwed to the ball screw 65, and an AC servo motor 67, and a small pulley 69 to the AC servo motor 67. The ram drive unit 4 1, in addition to the above-described respective portions, includes a position detector (transition encoder) 71 mounted on the rotating shaft of the AC servo motor 67, and position detection for detecting the vertical displacement of the ram 70). (Linear Scale) 73 » The data display unit 29 is a visible (portrait) material that is input to the data unit 100 and is input via the calculation unit 43 and which can be visually recognized by the input data. The data input unit 3 1 is provided with various buttons required to input various data to the control device; when the operator operates any of the buttons, an electrical signal corresponding to the operation is generated, and the data storage unit 45 is input to the control device 37. There are various kinds of information in the memory (such as the upper limit stop position data of the hammer, the falling speed data of the hammer 70, the position information of the collision speed of the collision money, the degree data of the hammer 70 after the speed switching, and the lower limit stop position of the hammer 70 ( Target position) The information on the pressurization action time of the material to be processed during the pressure operation, and the ascending speed data of the collision. The data storage unit 45 outputs the above-described one to the material display unit 29 via the calculation unit 43. The memory unit 45 inputs various data output from the data output unit 31, and the calculation unit 43 inputs the data. The operation preparation processing unit 47 is a processing unit that supplies power to the servo 31 from the power source 74. When the operation is prepared, the motor is slid coaxially with the ram, and the package is rotated, for example. 70, ί 70, the speed of the material, plus i key, 70 data, recorded by the operation of the enlargement button (not -12-201139008), at this time, the abnormality detecting unit 49 does not detect an abnormality. Further, by the operation of the input processing unit 57 that does not require the switching signal, it is confirmed that there is no input ', and the output is switched to the switching device 75, and the servo amplifier 39 is driven. In addition, even when the operation pedal is operated, the pedal is raised. When the foot pedal 19 and the operation start ready button (not shown) are activated in the state of the switch 15 are not output to the switching device 75, the abnormality detecting unit 49 notifies that the emergency stop switch 35 is turned on. The foot 3 3 is supplied via the input processing unit 57, thereby detecting that any abnormality has occurred on the main body side of the press molding machine. The abnormality detecting unit 149 notifies the abnormality processing unit 51 of the abnormality detection. When receiving the notification of the content of the abnormality from the abnormality detecting unit 49, the control unit 51 immediately stops the downward movement of the hammer 70, and stops the output of the switching device 75 that supplies the power to the servo amplifier 39; At the same time, the ram operation 'command unit 53 outputs a drive stop command to the AC servo motor 67 to the servo amplifier 39. The ram operation command unit 53 determines that the output from the foot side 3 3 is not output via the input processing unit 57. When the notification of the abnormality is indicated, a series of control operations of the ram 70 required to apply the bending process to the workpiece is performed, and a specific drive command is output to the servo amplifier 39. The rear gear operation command unit 5 5 is to be processed. The position of the material on the mold is positioned at a specific position, and a command for controlling the movement of the collision axis in the linear direction (moving back and forth) is issued. The input processing unit 57 is in addition to the various notifications from the side of the foot 3 3 described above. The current position information of the ram 70 outputted by the position detector (linear scale) 73 is also input, and the above notification or information is processed by the timer processing of -13-201139008. After that, the processing result is notified to each part of the control device 37. The output processing unit 59 is effective for the foot pedal when the abnormality detecting unit 49 determines that no abnormality has occurred in the pressure forming basic body from the side of the foot 33. The lamp 23 outputs a lighting command. The position detector 7-1 outputs a square wave pulse signal matching the number of rotations of the AC servo motor 67 to the servo amplifier 39. That is, the AC servo motor 309 is based on the control device 3. The drive command signal of 7 and the square wave pulse signal outputted from the position detector 71 adjust the magnitude of the motor drive current to the AC servo motor 37. Fig. 3 is a diagram showing the control system described in Fig. 2 causing the hammer An illustration of the migration of the target position (in the vertical direction). In Fig. 3, the vertical axis represents the position (in the vertical direction) of the hammer 70, and the horizontal axis represents time. The curve indicated by the thick line indicates the target position migration of the hammer 70 (vertical direction). In Fig. 3, first, after the intentional activation switch 15 is turned ON, if the operation foot pedal 13 is depressed, the ram 70 that has stopped at the upper limit position before starts to descend at a speed of, for example, 100 mm/sec. The stepping of the operation pedal 13 continues as described above. When the ram 70 reaches a predetermined specific position, the speed is switched to, for example, a speed of 10 mm/sec during the period from the specific position to the lower limit position, that is, the target position. decline. When the operation pedal 13 is continuously depressed, the ram 70 reaches the target position, and the workpiece is subjected to a pressurizing operation for 0.5 sec by the press die on the ram 70 side and the mold mold on the table side. Then, when the specific time elapses, the ram 70 starts to rise at a speed of, for example, -14 - 201139008 100 mm/sec, and finally returns to the upper limit position to stop the upward movement. Fig. 4 and Fig. 5 are flowcharts showing the control operation of the control system of the press molding machine shown in Fig. 2. In Fig. 4, first, the driving power of the servo amplifier 39 is turned on, and the preparatory operation operation of the pressure forming machine is started (step S1). Next, as a returning origin operation, the tamper 70 is returned to the upper limit position to form an initial stage of each part of the press molding machine (step S2). Next, as the operation data setting operation, the operator inputs the data on the operation (downward operation/upward operation) of the ram 70 to the control device 37 by operating various buttons arranged on the operation panel 27 (step S3). Next, as the operation start operation of the hammer 70, the operator presses a switch for starting the operation of the hammer 70 in accordance with the information on the operation of the hammer 70 input by the operator via the operation panel 27 (step S4). Next, it is checked whether or not the intentional activation switch 15 is operated (pressed) (step S5). If the result of this check is judged to be a (pressed) operation (YES in step S5), then it is checked whether or not the (pressing) operation of the intentional activation switch 15 is released (step S6). As a result of the check, if it is determined that the (pressing) operation is released (YES in step S6), the receiving process of the operation pedal 1 3 is performed, and even if the operator steps on the ram 70 formed by the operation of the foot pedal 13. The descending action becomes an effective process (step S7). Next, the effective timer initialization is intentionally started (step S8), and the pedal effective lamp 23 is turned on (step S9). Next, moving to Fig. 5, it is checked whether or not the operation pedal 13 is depressed -15-201139008 (step S1 0). If the result of this inspection is judged to be depressed (YES in step s), then as the ram start processing, the processing required to start the lowering operation of the ram 70 from the upper limit position to the target position is performed (step S1). 1 ). Next, the reception cancel processing of the operation foot pedal 13 is carried out (step S12), and the processing required to turn off the foot pedal effective lamp 23 is performed (step S13), and then the hammer operation command is output as the ram operation command.指令 Do the command signal required for the down action (step S 1 4 ). Next, it is checked whether or not the depression of the operation pedal 13 is released (step 515). As a result of this check, if it is determined that the depression has been released (Y E S in step S15), the lowering operation of the hammer 70 is stopped at this point of time (step 516), and it is checked whether or not the series of operations is completed (step S17). If the result of this inspection is judged to be completed (YES in step S17), after a sequence of operations required to stop the operation of the pressure forming machine is performed (step S18), a series of control operations are ended. Returning to FIG. 4 again, when it is judged that the intentional activation switch 15 is not operated (pressed) (N0 in step S5), the processing operation of step S5 is repeatedly performed before determining that the (pressing) operation is performed; When the (pressing) operation of the start switch 15 is not released (NO in step S6), the processing operation of step S6 is repeatedly performed until the determination (pressing) operation is released. Returning to Fig. 5 again, if it is determined that the operation pedal 1 3 has not been depressed (NO in step S10), after adding "1" to the intentional activation effective timer (step S19), it is checked that the effective timer is activated. The count 値 is smaller than a preset 値 (step S20). If the result of this check is judged to be -16:201139008 is large (NO in step S20), the same operation pedal receiving cancellation processing (step S2 1 ) as in step S12 is performed, and the same foot as that described in step S13 is performed. When the pedal effective light is turned off (S22), then the process shown in step S5 of FIG. 4 intentionally starts counting the effective timer. If it is not larger than the previous one (YES in step S20), the process proceeds to step S10. . When it is determined that the depression of the operation pedal 13 has not been solved, S15 is NO), the processing returns to the processing shown in step S14. Further, if the result of checking whether or not the series of operations is completed is completed (NO in step S17), the processing proceeds to the processing operation of the step house of Fig. 4. 6 , 7 , 8 , and 9 are diagrams showing a modification of the control operation of the control system of the pressure forming machine described in the sixth and seventh diagrams, and the processing operations are performed in steps S1 to S16. And steps S1 to S22 are respectively shown, and in steps 4 and 5, steps S1 to S16 are divided into processing operations, and steps S1 to S22 are respectively the same, and therefore omitted. A detailed description of these. In Fig. 7, when the lowering operation of the ram 70 is stopped (step S16), it is checked whether or not the ram 70 is descending in the lowering operation (step S29). As a result of the check, if the down operation is determined (YES in step S29), the initialization is stopped in the middle (step S30), and the person described in the foot pedal effective lamp 23 is simultaneously executed (the processing of the step 〇 setting) Xu (the step judges that there is no processing operation shown by the processing operation shown in the flowchart shown in Fig. 2 shown in Fig. 2, and stops the stop timer in the middle of the processing (step -17- 201139008, step S31) Next, moving to the eighth drawing, it is checked whether or not the operation pedal 13 is depressed (step S32). If the result of the inspection is judged to be depressed (YES in step S3 2), the process is started as a middle of the ram. The process required to restart the ram 70 from the stop position in the middle of the descent to the target position is performed (step S 3 3 ). Next, the reception cancel process of the operation foot pedal 13 is performed (step S 3 4 ), At the same time, the processing required to turn off the pedal effective lamp 2 3 (step S 3 5 ) is performed, and then the command signal required to restart the lowering operation of the hammer 70 is output as the ram intermediate operation command (step S 36) . Then, the operation proceeds to the operation shown in step 15 of Fig. 7. On the other hand, if it is determined that the operation pedal 13 has not been depressed (NO in step S3 2), the timer is added to the stop timer. Thereafter (step S37), it is checked whether the count of the stop timer is smaller than the preset threshold (step S38). If the result of the check is judged to be small (YES in step S38), then step S12 is performed. Or the same operation pedal receiving cancellation processing (step S39) as described in step S21, and performing the same step of turning off the pedal effective light (step S40) as described in step S13 or step S22, and then moving The processing operation shown in step S5 of Fig. 6. If the count of the stop timer is not smaller than the preset threshold (NO in step S38), the processing proceeds to step S32. 〇 Returning to FIG. 7 again, if it is determined that the ram 70 has not stopped descending during the lowering operation (NO in step S29), then moving to the ninth figure, -18-201139008, checking whether the series of operations is ended (step S4 1) If the result of this check is judged to be the end ( If the operation required to stop the operation of the pressure forming machine is performed (step S42), the series of control operations is terminated. If the result of checking whether the series of operations is completed is determined to be not completed (NO in step S4 1), Then, the processing moves to the processing shown in step S5 of Fig. 6. The preferred embodiments of the present invention and the modifications thereof have been described above. However, this is an example for explaining the present invention, and not the present invention. The scope is limited to the meaning of the embodiments and the modifications. The invention can also be embodied in other various forms. For example, instead of intentionally activating the switch 15, a manually operated intentional activation button, or an optical sensor, may be provided at an appropriate location on the operating panel 27. Alternatively, the operator's voice and term may be pre-registered by voice recognition technology, and the ram may not be activated unless a combination of keywords, such as "hammer" or "action", is input. Furthermore, it is also conceivable that the ramper can be activated by the operator blowing or moving a part of the operator's body.
