Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to an ink-washing machine, and more particularly to a press machine that uses a feeding machine to control the slider to be lifted and stopped to perform pressing. [Prior Art] · The press machine has an upper mold and a lower mold, which are pressed by the workpiece in the vertical direction, and the slider is fixed with the upper mold on the lower side to make the lifting movement; The slider is moved up and down; and the switching mechanism converts the rotational motion of the drive motor into a lifting motion and transmits it to the slider. In the operation of the press machine, the workpiece is formed by stamping. Etc.) Move out between the upper mold and the lower mold, and press the plate before the press processing = between the upper mold and the lower mold. Therefore, for each forming-sheet member, the weight is 2 sliders, stop, wait (4) After the movement is completed, the slider is operated again. The lowering, rising, and stopping of the slider are performed every cycle: 'Therefore, it is desirable to switch from stop to fall and from rise to stop. Therefore, the servo control can be used for the control. In the servo control 2 press machine, the servo control of the motor rotation angle can be used to increase and decrease the speed and stop, so the slider movement rises to stop From: to: The reduction of the knife can be carried out in a short period of time. The use of the above-mentioned feeding service control 'pressing machine is described, for example, in the following patent documents, the special literature, the literature 1] Japanese special open 2005_271〇7〇 bulletin In the stamping machine, there will be a balancer (Counter Balance) that is used to resist gravity and support sliding 320035 200918300. In this case, although there are two kinds of forces on the slider: by its own weight The force pulled below and the force lifted up by the balancing device, but the two usually do not balance. Therefore, in the press machine using servo control, in order to keep the slider in the stop position, the servo motor must be Torque is generated, so that a current flows through the servo motor and generates heat, which causes waste of energy. "In addition, while the slider is stopped, the rotation angle of the servo motor and the phase are fixed at the slider stop position. The servo control is performed in a manner that the rotation angle is the same. Due to the slight difference between the rotation angle and the detection angle value, the servo motor repeats the slight forward and reverse movement. Therefore, from the servo motor to In the power transmission path of the block, it is possible that the phenomenon of repeated contact with the tooth surface between the gears causes deterioration of the power transmission mechanism. The waste of the moon and the deterioration of the power transmission mechanism are particularly remarkable when the slider stop time is long. For example: When the manual or low-speed conveying device is used for ordering, when the workpiece is moved in and out of the mold, the stopping time of the slider becomes longer, and the waste of energy and the deterioration of the power transmission mechanism are more conspicuous. [Summary of the Invention] The purpose of Ming is to provide a stamping machine that can prevent the contact between the gears due to the servo weight (10)...reverse motion when using the =pressure machine in the stop state of the slider. The surface defect causes deterioration of the power transmission mechanism. In order to achieve the above object, the present invention provides that the upper mold and the lower mold are attached to the upper mold and have the ink, and the slider is fixed on the lower mold to form the upper mold. Carrying out the lifting and lowering of the cookware for lifting movements, · Servo 320035 6 200918300 - The motor is used to lift the slider; and the changing mechanism is to make the servo horse _, the rotation movement Converted into a lifting motion and transmitted to the slider; the stamping machine is provided with: a control device, which is a commanded rotation angle value according to a slider action mode for imparting a desired slider motion, and a rotation angle of the servo motor The detected values are compared to control the rotation angle of the vocal motor according to the above-mentioned command rotation angle value; the switching mechanism is set from the feeding motor to the ^=power transmission path to 'selectively switch ··from The movement of the servo motor reaches the power transmission state of the slider, and the power transmission non-transmission state of the motor is not transmitted to the slider; and the lifting movement of the slider holding the magazine _ 吏 'month block is not Restricted non-retaining shape: "The slider holding the slider's lifting movement is restricted. The slider stopping holding mechanism is switched to the slider holding state by the rotation angle control of the feeding motor: The switching mechanism switches to a power non-communication state. In addition, in order to achieve the above-mentioned purpose, it is too conscientious to win the beauty of the invention. There are two types of stamping machines: the upper mold and the lower mold, which are clamped in the vertical direction to carry out the slider, and are attached to the lower y puller. Carrying the material to transport the U machine, and then making the block structure, the rotary motion of the feeding motor is converted into the lifting and lowering method. Features: The selection of the cutting machine is selected from the servo blade. Path: Make the movement from the feeding motor; ^ = two-power transmission: and do not let the power from the feeding motor communicate to the conveyance of the situation, set the selective switch... not convey the slider of this evil Holding mechanism ··320035 7 200918300. The non-retaining state of the slider lifting movement is unrestricted, and the slider holding state that limits the movement of the slider. The movement is based on the movement of the slider to be desired. The command rotation angle value of the slider action mode, the more the feed is found: the detected values of the rotation angle are compared, and the rotation angle of the feeding motor is controlled according to the above-mentioned command rotation angle value, thereby lowering the slider to perform the punching After y The slider is raised and stopped at the target stop position; after the slider stops at the target stop position, the slider holding mechanism is switched to the slider state i and the slider holding mechanism is switched to the slider holding shape. Then, the switching mechanism is switched to the power non-conveying state. In the above-described press machine and control method therefor, after the slider is stopped by the rotation of the servo motor, the slider is held, and the switch mechanism is powered. Non-communicating status. Therefore, in the stopped state of the slider, it is held by the slider holding mechanism, so that β is maintained to keep the slider in the stop position, and the current is applied to the servo horse gB Α ^ because the servo motor and the slider are Separately, the power is not transmitted, so the servo is small, and the torque required for the positive reversal of the motor + motor = the result, the current supplied to the motor can be made smaller. Therefore, the power consumption in the stop of the slider can be reduced. In addition, in the stop of the slider, since the feeding and reversing movements do not convey the slight repetitive positive movements of the motor, the mechanism of self-feeding motor 7 is separated from the power transmission. Wei π, the power transmission path of the heart block, so there is no slight repetitive motion in this work. Therefore, it is possible to prevent deterioration of the power transmission path due to repeated connection between the gears. & contact-surface search leads to power transmission 320035 8 200918300 The positive motor:::=:: can reduce power consumption and prevent the deterioration of the feed-to-power transmission mechanism and the repeated contact of the tooth surface between the wheels (4) Separating the two 'can still be used _ machine two (2) because the slider holding mechanism is sliding in the stop at the start of the operation - the door of the slider holding mechanism and the power transmission mechanism:: due to the braking effect Friction and heat. In addition, in the meeting, the slight forward and reverse movement of the feeding motor will not be transmitted to the = will be between the m slider holding mechanism and the power transmission mechanism (3) and the use of the conventional servo control press machine Similarly, since the slider movement is controlled by the = service control, the movement of the slider from the ascending to the stop, and the stop to the lower can be performed in a short time. (4) The energy can be regenerated by changing the power supplied to the servo motor during the deceleration of the slider to improve the efficiency of energy use. According to the above, the present invention can reduce the power consumption by using a servo-controlled press machine, and can prevent the power transmission mechanism from being repeatedly contacted between the gears due to the slight forward and reverse movement of the servo motor. deterioration.

"The shield path cuts the power from the reward 7 to the slider 5 to transfer the ground. The following two states of the structural power are transmitted to the power transmission state of the slider 5, and the two mechanisms 13 are not supported by the feeding; After the switch is stopped, the slider 5 is placed with the ==1:::: to the phase # in the power transmission state - the electromagnetic force drives the position of the heart 9 by the control of the control 1: 2:1 corner.

Further, the motor drive amplifier i丨c uses a structure such as a 4-quadrant control inverter that can regenerate energy, thereby reducing the energy loss when the motor energy is converted to electric energy when the word motor 7 is decelerated. Further, the servo motor 7 can use an induction motor, a synchronous motor motor or the like. . . The motor rotation angle encoder 17 can use an optical encoder or a resolver ° / outer' in the figure of the figure, and is provided with a crankshaft rotation angle encoder 19 for detecting a crankshaft 后 which is described later. And will rotate the crankshaft from the crankshaft: rotation angle code H 19 ::,. / "Crankshaft 9" "... 2:: 2 This hunting can calculate the crank angle of rotation and the height of the slider. Therefore, the crankshaft rotation of the wheel of the press machine controller can be used for motion confirmation. The crankshaft rotation angle encoder is a pre-learning encoder or a retractor. The construction of the other parts of the press machine 1G will be described next. The rotation of the motor 7 is transmitted to the speed reducer via the clutch 13 320035 13 200918300 = The speed reducer 21 decelerates the rotation, and the shaft 9a is rotated by the rotation of the speed reducer 21. The crank shaft 9a and the slider 5 are coupled by the connection 2, and the crank shaft 9a- rotates, and the slider 5 moves up and down. For this, the reduction gear 21 can use, for example, a mechanism for the number of teeth. The number of different gears or bevel gears meshes with the lower mold and is mounted on the carrier plate 23. The press is applied to the load system of the upper mold 3a. Through the slider 5, the connecting rod 9b, and the crank, the upper part of the frame 25 is selected, and the (4) dry 9b crank bearing plate 23 is operated to form the frame 25, and the load of '3b is processed by the lowering. :: ^ between, slip (four) ^ mold and "the lower mold 3b is in contact, The upper cooker 3a and the lower changer 3b will be attached to the processed material. In addition, in order to support the slider 5盥^ " device...the mechanism of the balance device 27=3; , ^ 97 4 1 Figure does not 'can be used to the following for the above configuration of the + balance set. To illustrate. Fig. 2 is a flow chart showing the control method of the pirate 10 plus the control method of the step S1. Get ready. Control (four) set〗 "Spiriting of the heart machine is not communicated from the servo motor 7" When the Ha is in the power structure 13 (in the first picture): the switching mechanism 13 of the power non-communication state is switched to the power transmission force Instructing the switch to turn the hold release finger a to the switch controller in the above-mentioned slider holding state, and the mechanism 15 (in the first figure, /, 使7 switches the slider holding mechanism 15 to 320035 14 200918300 The state of staying. In addition, in step S1, the control device continues to staple the feeding control to maintain the feeding motor 7 at a constant rotation angle. In step Μ, the slider 5 is lifted and lowered for pressing. The device you = lowers the slider 5 to perform the stamping process of the material 1 and again raises the slider 5 and stops the control at the eye position. During this period, the first-two-1 stamping machine controller mountain The output rotates according to the command rotation angle value of the slider operation mode, and the motor rotation angle η outputs the angle value of the detection rotation angle value of the servo motor 7, so as to follow the command rotation angle angle value and the detection rotator nc to control the feeding service. Motor via motor In the meantime, the up and down movement of the slider 5 is increased. In the feeding machine motor 7 decelerate to keep the slider 5 in the stop of your ¥ output with the slider stop position on the nf system mountain system... exercise servo, ...: two ^ value consistent control. By this, make _ = / In addition, the target stop position (four) is at the target stop position. The high position, that is, the upper of the slider 5:: and =9b become the most, after the second: the second slider 5 stops at the target stop The position holding command 'makes the slider holding mechanism 15 (the ==5 output slider is held to the slider holding state. Thereby, the ° "brake" action & month block 5 is held at the target stop position. 320035 15 200918300 . In step S4, the press machine controller & (4) mechanism, 13 (in the case of the i-th diagram is a clutch), a power non-communication command (a separate instruction from the crying instruction) is made to switch the switching mechanism 13 to a power non-conveying state. (clutch;; separate Thereby, the driving force of the feeding motor 7 is not transmitted to the state: 'The slider holding force of the slider holding mechanism 15 is maintained so that the slider 5 is served." Therefore, the motor 7 is driven only. The state of the body of the body is caused by a slight deviation of the commanded rotation angle = degree value, and the small forward and reverse movement by the ship control is repeated, but only a small torque is generated. As a result, = servo motor 7 And the motor drive amplifies the crying IL, and the current of the bite %勑裒大勑裒丨丨c becomes smaller. In the stop state of the slider, the manual operation or automatic movement of the material is used: =: the processed material is processed by stamping 1 'and the new 'added, f Cao', 3b above. Thereafter, the process returns to step S as described above for the stamping process. In addition, in the above-mentioned stamping plus lp, in the middle of the cymbal, the crankshaft is rotated by the angler..., the action t: is input into the press machine to control the gamma", that is, the switching mechanism 13 is the power transfer to: The rotation angle of the second motor 7 and the rotation angle of the crankshaft 9a should be changed in proportion to the reduction of the speed of the reducer 21 by the llaf. kb, so that the press mechanical control 114 is compared with the motor by two angles. The degree of rotation with the crankshaft rotation (four)^ is determined to be abnormal if it is not the same as that of the reducer 21, and the rotation angle detected by the benefit of 19 jin. When the ratio of the slider holding structure = R sample changes Then, the crankshaft 9a is not in the state of the slider holding position (3) red 4v, so the stamping machine controller Ua checks 320035 16 200918300 := Whether the rotation angle has not changed, and the operation when it is determined that the abnormality is broken is Abnormality: When the feeding motor 7 is stopped, the 丄 丄 丄 - 定 定 定 llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc Circuit (not shown), etc., or the present invention In the stamping machine method of the embodiment, the slider 5 is stopped by controlling the servo control arm angle, and the frame 13 is moved: the non-transmission = is:::r state' The switch slider 5 is h, and in the stopped state of the slider 5, the slider holding mechanism 15 is held, so that the current of the slider 7 is not increased to the servo motor 7, and the servo horsepower is not transmitted. The electric furnace #1 η , , · , which is the torque of the positive rotation of the motor 7 , which is reversed by 7 , causes the servo motor κ claw to be small. Therefore, the power consumption in the stop of the slider can be reduced. In addition, during the stop of the slider, the slight repetition of the servo motor 7 and the turning motion are not transmitted to the power transmission from the position where the power transmission from the servo motor 7 is separated by the switching mechanism 13 to the slider 5. The path, therefore, does not produce a slight repetitive motion in this power transmission path. Therefore, it is possible to prevent the deterioration of the power transmission mechanism caused by the repeated contact of the tooth surface #❿ between the four power transmission paths. Therefore, in the stop of the slider, the power consumption can be reduced and the deterioration of the power transmission mechanism caused by the meshing portion between the gears repeatedly contacting the tooth surface due to the forward and reverse movement of the servo motor 7 can be prevented. 17 320035 200918300
