[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying an operation screen of a servo transfer feeder device and a recording medium for the operation screen display program.

[0002]

2. Description of the Related Art A servo transfer feeder is a transfer feeder device driven by a servomotor for transferring a work between press steps in synchronization with a slide of a transfer press, and has been widely used in transfer press processing. I have. As shown in FIG. 15, a general servo transfer feeder device includes a pair of right and left feed bars 21 and 2 in the work transfer direction.
The pair of left and right feed bars 21 and 21 has a plurality of pairs of fingers 22 and 2 facing inward facing each other.
2 are attached at predetermined intervals. A pair of right and left feed bars 21 and 21 are respectively provided in three directions of a front-rear direction (hereinafter referred to as a feed axis), a left-right direction (hereinafter referred to as a clamp axis), and an elevating direction (hereinafter referred to as a lift axis) (hereinafter referred to as a feeder axis). ), And are driven in synchronization with each other by a crank angle of a slide of a transfer press (not shown) by servo motors provided for each direction. The control device (not shown) determines the amount of each movement stroke in the three directions, the crank angle for starting each movement (hereinafter referred to as an operation start angle), the crank angle for ending each movement (hereinafter referred to as an operation end angle), and the like. The set motion curve is stored in advance, and the servo motors are servo-controlled in synchronization with the crank angle based on the motion curve.

[0003] Many techniques related to the method of setting each feeder axis of the control device of the servo transfer feeder device as described above have been proposed in the past, for example, Japanese Patent Publication No. 7-85.
Japanese Patent Application Laid-Open No. 819 and 7-275971 are known. According to the descriptions in these publications, when the movement stroke amount, the operation start angle, and the operation end angle of each feeder shaft are set from a predetermined input device, the motion position of each feeder shaft is determined in correspondence with the crank angle. , And image processing is performed on the basis of the calculation result to display a slide and an operation diagram of each feeder axis (hereinafter, referred to as a slide motion and a feeder motion, respectively) on the CRT. Also,
At the time of actual machining, the control device obtains the target position of each feeder shaft corresponding to the crank angle of the press based on the calculated feeder motion, and the deviation between the position feedback value of each feeder shaft and the target position becomes smaller. In this manner, the speed and position of each feeder axis servomotor are servo-controlled, and are continuously controlled in synchronization with the crankshaft.

[0004]

However, Japanese Patent Publication No. Hei 7-85819 and Japanese Patent Laid-Open Publication No. Hei 7-275971 describe the above.
The control device for a servo transfer feeder disclosed in Japanese Patent Application Laid-Open Publication No. H10-15095 has the following problems. (1) In a forging press, a bed knockout (hereinafter, referred to as BKO) device for extruding a molded product upward from a lower mold so as to be easily gripped by a finger 22 of a transfer feeder is generally used. Many.
Then, the knock pin of the BKO device is moved up and down in synchronization with the slide, and the molded product is pushed upward to substantially move the BK product.
It is necessary that the finger 22 be held at the upper end position of the knock pin of the O device. That is, the operator needs to know how many mm before the upper end position the knock pin of the BKO device is at a certain crank angle. However, conventionally, only the slide motion and the feeder motion based on the data of the set movement stroke amount, the operation start angle and the operation end angle are displayed on the CRT, and the BKO motion, that is, the crank angle and the knock pin upper end position of the BKO device are displayed. Is not displayed. Therefore, as described above, since the operator does not know how many millimeters before the upper end position the knock pin is, it is difficult to check for interference during the transportation of the forging press.

(2) In a sheet metal press (a punching process, a forming process, etc.), in addition to a slide motion and a feeder motion, it is required to display an interference curve in order to check interference between a finger and a die. Often,
The prior art described in the above publication cannot display an interference curve. (3) Although motion data is registered and managed in correspondence with each program number, setting data of peripheral devices such as a material supply device, a mold lubrication spray device, and an ejector device used in correspondence with the same motion are stored. I cannot register. For this reason, the operator can read the motion data corresponding to the program number, but it is necessary to set the peripheral device data corresponding to the motion data each time. Therefore, there is a problem that the setting operation is troublesome, a setting error easily occurs, and a time required for the test hit is long. (4) Further, it is not possible to set the two-stage motion of the feed shaft and the clamp shaft generally required for a forging press. As a result, the number of types of molded articles to be processed is reduced, and the versatility of the servo transfer feeder device is lost.
The scope of application is limited.

The advance and the clamp respectively correspond to FIG. 9 and FIG. 11, and represent the motion set to the two-stage motion. In these drawings, the same components as those in FIGS. 4 and 3 are denoted by the same reference numerals, and description thereof is omitted.

On the two-stage motion setting screen, two setting columns are provided for an operation start angle, an operation end angle, and a stroke amount for advance and clamp, respectively. That is, advance 1 and advance 2 can be set for advance, and clamp 1 and clamp 2 can be set for clamp. When setting data is input to two setting fields at the same time, a two-stage motion is set. When setting data is input to one of the two setting fields, the same setting as the standard motion is made. .

It is assumed that the range from the operation start angle to the operation end angle of the advance 1 and the advance 2 is closer to the advance 1 than the advance 2 and does not overlap. Similarly, the range from the operation start angle to the operation end angle of the clamps 1 and 2 is such that the clamp 1 is closer to the clamp 2 than the clamp 2 and does not overlap. Further, each of the curves of the advance 1, advance 2, clamp 1 and clamp 2 is created by a cycloid curve, like the stroke movement curve of the other feed shaft.

Next, the motion transition function by the motion transition angle setting section 55 shown in FIGS. Touching the motion transition angle setting unit 55 during the data correction mode or the new data setting mode makes it possible to set the motion transition angle, and the setting unit 55 is displayed in reverse or blinking to change the setting possible state. Represent. In this state, the transition angle data is inputted by the numerical keys of the numeric keypad (not shown),
It is designed to take in U7. Then, when the data registration key 59d is touched, the transition angle data is stored in the external storage device 3 and the external storage device 4 as the motion data of the motion number together with each setting data of the setting screen. Thereby, the motion curve in which the motion transition angle data is set is, as shown in FIG.
All the feeder shafts are curves that are shifted in parallel by the crank angle corresponding to the set transition angle. At this time, the rotary cam signal on range of the peripheral device data is also shifted in parallel by the crank angle corresponding to the same transition angle.

Further, the display device 1 of the present invention can monitor various operating states in the production mode and the manual operation mode. FIG. 12 shows an example in which the display device 1 displays the crank angle and slide position of the press, the current position of each feeder shaft, the BKO pin position of the BKO device, and the like. At the same time, press,
Each setting data of the feeder device and the peripheral device is displayed, so that the comparison with the above-mentioned present value is easy. In the present embodiment, an example is shown in which a pair of right and left feed bars 21 and 21 are driven in a left-right synchronous manner by two servo motors for the clamp shaft and the lift shaft. The present value display is performed for each of the pair of left and right servomotors.

According to the above configuration, the following operations and effects can be obtained. (1) A slide, a feed axis, a clamp axis, and a lift axis of a servo transfer feeder device when a press machine operator having a control device based on the operation screen display method of the servo transfer feeder device according to the present invention creates motion. , And BKO are graphically displayed on the display device, and all the stroke values are also displayed on the same screen. It is also possible to print out these motions and stroke values. Thereby, even if it is conventionally difficult to determine each set data of the motion in relation to each axis, it can be easily set. For example, when both motions of the clamp and the lift are wrapped, it is easy to determine the numerical values for the set values of both the motions. Alternatively, for example, when creating a motion for scooping and transporting a stepped workpiece with a finger, the relationship between the BKO pin and the clamp can be read strictly with a numerical value and a motion diagram, which is effective for interference check at the time of finger design. . In this way, the relationship between the motions can be easily and strictly read, so that the motion can be easily created and the creation cost can be reduced.

(2) When a two-stage motion can be set, a device that sprays the mold lubricant onto the workpiece by temporarily stopping or stopping the movement of the feed shaft during the advance of the feed shaft is used. And shafts (long)
In the case of moving the clamp shaft early by a predetermined amount in the clamping direction so that the molded product does not fall down when the molded product knocks out during the molding, and the workpiece is first supported by the fingers, the transfer with two-stage motion is required. It can be done according to the type of work. Therefore, the types of work that can be processed are increased, the applicable range is widened, and the versatility of the press machine can be improved.

(3) Only by inputting the data of the stroke amount and the press speed of each feed shaft, the minimum allocation angle required to move the stroke amount is automatically calculated.
When the allocation angle between the set operation start angle and operation end angle is smaller than the calculated minimum allocation angle, the minimum allocation angle is displayed so that the setting can be redone. When creating a motion, a motion appropriate for each servomotor of the servo transfer feeder device can be created. That is, the setting can be made according to the capacity of the servo transfer feeder device (that is, the maximum rated output and the maximum rotation speed of the servo motor). Therefore, overload of the servomotor of the servo transfer feeder device is prevented beforehand, so that the life of the servomotor can be extended and a servo transfer feeder device with less failure can be obtained.

(4) The interference curve calculated on the basis of the set motion data can be graphically displayed on a screen or printed out, so that a sheet metal press (forming or punching) or the like can be performed. At this time, the operator can easily check the interference between the finger and the mold. Thereby, the mold design and the motion setting can be easily and accurately performed, so that the mold designing operation and the motion setting operation can be efficiently performed.

(5) Peripheral device data can be registered together with motion data in correspondence with a motion number, so that motion data and peripheral device data are separately set and managed as in the conventional case. It is no longer necessary. Therefore, since the motion data and the peripheral device data can be centrally managed by the same motion number, the setting can be facilitated and the setting error can be eliminated. Also, during actual machining, by simply selecting one motion number, the corresponding motion data and peripheral device data are read out automatically and without an error in the correspondence, so that the control of the feeder device and the peripheral device is ensured. Can be done accurately.

(6) After setting the feeder motion data, when the type of separation device (pusher device or lifter device) is selected on the peripheral device data setting screen, the maximum operating speed value of the drive cylinder of the pusher device or lifter device, and Based on the set press speed data,
Since the rotary cam-on angle range of the peripheral device data is automatically set, when a new motion is created, the trouble of setting the rotary cam-on angle range by trial and error in accordance with the motion can be omitted. In addition, together with the separation device,
The misfeed detection or the setting of the rotary cam-on angle range data of the ejector device is also automatically set. In addition, if a trial shot is performed at the actually set rotary cam angle and the rotary cam on angle is to be corrected based on the result, the set value can be changed by re-inputting the numerical data. The change of the set value is optional and easy.

(7) Since the feeder motion is entirely shifted according to the set motion shift angle, it is not necessary to re-input each set data, and the operability at the time of data change can be improved. . Further, along with the entire transition of the feeder motion, all the setting data of the peripheral cam, the misfeed detection and the rotary cam angle of the ejector device are also shifted according to the motion transition angle, so that the peripheral device, the misfeed detection and the ejector The operability can also be improved for setting the rotary cam angle of the device or the like.

The above-mentioned motion transfer function is particularly effective in an automatic forging press apparatus as follows. For example, in the case of a bevel gear work, as shown in FIG. 13, when the work W is clamped with the fingers 21a, 21a, the timing of pushing up by the mold ejector pin 41 of the BKO device and the timing of clamping by the fingers 21a, 21a are different. In many cases, the clamp can be reliably performed by delaying the clamp timing. In this case, the work W can be smoothly transported by delaying the entire motion. At this time, it is necessary to change the timing of misfeed detection or the like in accordance with delaying the entire motion. However, in the conventional setting method, the changed data is re-input one by one. According to the motion transition function, the rotary cam angle set value for misfeed detection is also shifted by the motion transition angle, so that the trouble of resetting can be saved.

For example, as shown in FIG.
The workpiece W may jump due to the mold ejector pins 41 of the apparatus, and therefore, the timing of clamping by the finger 21b is advanced, and
There is a case where the work W is desired to be suppressed from above by the work jump prevention plate 23 attached to the work. At this time, according to the present motion transfer function, the setting data can be easily changed, and a test hit can be performed based on the changed data to immediately confirm the effect of preventing the work from jumping. As a result, the data change and the confirmation test by the trial hit can be performed in a short time, so that the work efficiency can be greatly improved.

(8) Since the data input means and the display device are constituted by a touch panel display, various types of data can be obtained by combining display contents of one screen display and switch setting of one transparent touch key. Setting can be easily performed, and the configuration can be made compact and downsized. Further, by operating the transparent touch key set on the display unit, the operation can be easily and surely performed, and there is no erroneous operation, so that the operability is good for the operator.

As described above, according to the present invention, the feeder motion, the slide motion and the BKO motion based on the motion setting data are simultaneously confirmed by screen display or print output (that is, on the same screen or on the same print). Therefore, the relationship between the position and the timing between the BKO and the slide or feeder shaft is easy to understand, and the check is easy. In addition, an interference curve is created based on the motion setting data and is displayed on a screen or printed out, so that an interference check can be easily performed. In addition, 2
Since the step motion can be set, the applicable range of the work is widened, and a highly versatile servo transfer feeder can be obtained.

In accordance with the motion number, the rotary cam angle data of the peripheral device, misfeed detection and ejector device can be set together with the motion setting data, so that various setting data can be centrally managed with the same motion number. In addition, it is possible to facilitate the setting operation and prevent erroneous setting. In addition, since a work name or the like can be registered as a memo, it is easy to confirm data of workers and confirmation of communication items. To drive within the maximum capacity of the servo motor,
The minimum allocation angle according to the stroke amount and slide speed of each feeder axis of the feeder motion is calculated, and the allocation angle based on the operation angle setting data is set to be larger than this minimum allocation angle. Can be extended to extend the life.

When setting the peripheral cam, misfeed detection, and setting of the rotary cam angle of the ejector device, the setting data is automatically input according to the setting data of the feeder motion, and the input data can be corrected if necessary. Therefore, the data input work of the operator becomes easy and the operability is good. Furthermore, since the motion data and the rotary cam angle data can be transferred collectively by the motion shift function, the operability can be improved.
