Description of the Invention: [Technical Field] The present invention relates to a molding machine, and more particularly, a motor of an injection molding machine as a driving source of a driving mechanism [Prior Art] The molding machine of the injection molding machine, etc., has an injection device, a model device, and a mold clamping device, and emits a dream, a system, a heating cylinder, and a screw. Coronation # a# 隹 Heating, the fly cylinder can be freely swivelled, and can be set freely to retreat. In the ten-mile operation, it is supplied to the twisting: the resin of the cylinder is heated and melted. It is accumulated in front of the screw. :: In the operation, the screw and the shovel are advanced, and the resin accumulated in front of the screw is filled in the cavity space of the model device. The model device is equipped with a fixed model and movable. Model. The clamping device is provided with a solid, ten σ for women's movable model, a movable platform, and a toggle mechanism for moving back and forth from the j. Toggle machine Constructing and moving the movable platform forward: The dynamic model is contacted in the fixed model and closed. By closing the mold, the cavity space is formed between the fixed model and the movable model. The mold clamping force, the movable mold is pressed to perform the mold clamping. , ^ π , the molten resin filled in the cavity space is cooled by the cooling of the model device. Thereby, the molten resin is solidified, and the mold is cured. In the cavity space, it becomes a molded product. Then, the toggle mechanism is actuated, and the movable platform

Be back. Thereby, the movable model is separated from the fixed model. At this time, the ejector device which is provided on the movable platform and is used as the F-moving device is actuated. That is, the ejector pin (P i η ) as the driven portion is protruded' to perform demolding. For the weeping I top, the front end of the ejector pin is facing the upper jaw cavity space, and the rear end is fixed to the apate. Further, the top a money device is coupled to the rear end of the ejector plate by the ejector rod (4). The ejector pin transfer device includes a motor as a drive unit, a ball screw, and the like. When the motor is driven while the mold is being opened, the turning force generated by the motor is transmitted from the output shaft to the ball screw. In the ball screw, the 'slewing motion system is converted to a linear motion, and the linear motion is transmitted to the ejector pin via the ejector rod, so that the ejector pin is advanced. Therefore, the molded product remaining in the movable model is ejector The pin is protruded and the die is released (for example, refer to Patent Document 1). However, the state of the line is fat. In this case, in the case where the model device is cleaned, the mold is removed, and the top of the tree, which is attached to the fixed model and the movable model, is removed, and the workpiece is cleaned. When the operation of the motor is stopped, the ejector pin is fixed in a predetermined working position. In this way, when the cleaning device is operated and the ejector pin is moved (retracted) for any reason such as an external force during the cleaning operation, the operation cannot be performed by I'. Therefore, as a motor for driving the ejector pin, it is considered to use a motor with a brake, which is equipped with a brake plate and a brake.

However, the braking effect is weakened by the friction state of the brake plate and the brake pad, and it is feared that the above-mentioned ejector pin can be moved for some reason: Therefore, it is preferable to know in advance the friction state of the brake plate and the brake pad. Ground. However, in the motor with the brake, since the brake device is covered by the motor cover (motor CQver), the friction state of the brake plate and the brake pad cannot be grasped. Therefore, there is a problem that the maintenance time of the brake device cannot be correctly known. Further, in the mold-locking motor as the drive unit, the brake motor is also used. In this case, when the external friction is applied to the model device by the friction state of the brake plate and the brake cymbal, the movement can be prevented and the workability is poor.

In the case where the injection molding machine and the servo motor for the fraud are provided with the brake device, the braking torque for holding the constant torque of the service motor is selected. Therefore, as described above, in the % of the servo servo brake device & p-manipulator of the ejector device, there is also a biasing force ratio of the return spring 9: the servo motor's constant torque Tc is generated. The situation of large thrust. Here, the pin 1 - 1 is pulled up and down by the torque T (Tp < T < Tc) between the rated torque Tc of the servo torque and the highest (Peak) torque Tp. On the other hand, in the case of performing maintenance inspection of the ejector device, it is necessary to make the ejector pin Η 突出 as a protruding state. In this case, even if the servo motor for driving the brake ejector device is braked, the ejector pin η may be bounced back by the return spring 1-9. Further, in the field where the position is controlled only by the servo controller, there is also an erroneous operation: Therefore, it is desirable to cut off the power of the servo motor by holding the position by braking. In addition, since the injection molding machine usually drives the locks independently and intermittently, the top-out device is disposed, and the side output is higher than the rated torque that is specified in the continuous operation, and the side is operated. There are many situations. In this case, the fJ dynamic torque can be operated while the constant torque of the servo motor is specified, especially when the servo motor is operated at the maximum torque Tp. Even if the brake is not released, the brake can be actuated, that is, the brake can be actuated while the brake is being applied. That is, the brake device is driven by a brake drive circuit other than the servo driver, although

The brake drive circuit is provided with a __third relay (relay) 22 223 for detecting a disconnection. The exciting coil of the first relay 221 is connected between the two wirings 2 2 5 , and the exciting coil of the second relay 2 2 2 is connected to the driving circuit input of the braking device 1 74. The exciting coil of the third relay 2 2 3 is connected to the input/output circuit 2 1 〇. The two a-contacts 223c of the third relay 223 are two wirings 225, and are connected to the connection portions of the first electric appliance 2 2 1 and the wiring 2 25 . The position of this connection portion defines the detection range of the disconnection of the wiring 2 25 which will be described later. That is, the wiring 2 2 5 between the two a contacts 223c of the second relay 223 and the brake device 1 74 becomes the detection range of the disconnection. Therefore, the connection position of the two a contacts 223c of the third relay 2 2 3 is preferably close to the brake drive power supply circuit 220. Further, in the brake drive power supply circuit 22, the lighting circuit 227 of the lamp 226 composed of an LED or the like is connected. In the lighting circuit m, one side of the two a contacts 221c of the first relay state 221 and the side of the two b contacts 222e of the second relay 222 are connected in an in-line manner.

At this time, the controller is U 230, so that the brake and the disconnection of the drive circuit are displayed. The brake drive circuit operates as follows. :: Issue: Servo motor 172 is activated by brake splitting:,. The braking torque Tb is generally greater than the maximum torque Tp of the ejector 72. When the brake of the brake device 174 is released, the controller m turns on the third relay via the input/output circuit 21G. In short, the a contact 223c of the third relay 223 is closed, and the straw is supplied by the electromagnetic brake receiving power of the brake device i 174, and the brake system for the ejector servo track i72 is released. In the above-described state energy I, by the fact that a relay 221 is excited, the a contact 221c becomes; σ, the second relay 222 is also excited, and the b contact 222c is turned on, and the result light 226 is not lit. . However, if the wiring 225 is broken, the power to the brake device 74 is 'interrupted'. As a result, the ejector motor 172 is braked. At the same time, the second relay 222 is turned on by being not excited, and its contact 222c is closed. As a result, since the first relay 22i is in an open state, its a contact 221c is closed, so that in addition to the lamp 226 lighting, this is transmitted to the controller 2A. The controller 2 displays a disconnection on the display unit 23A. On the other hand, the ejector servo motor 丨 72 is in the slewing state, and the brake device 174 is in an unactuated state. That is, the electric power from the brake drive power source circuit 220 is supplied to the brake device 1 74. In this state, when the wiring 225 is broken, the servo motor i 72 is used for the ejector.
7041-6769-PF 30 1252155 動裝置174進行制動。同時，第二繼電器222係藉由成 為沒有激磁而成為關閉，其b接點成為閉合。結果是因 為第一繼電器221係在開啟的狀態下，且其a接點221 閉合，所以除了燈226點燈之外，同時此係被傳達至控 制器200。控制器2〇〇除了在顯示部23〇顯示斷線之外， 經由伺服驅動器2，使頂出具用伺服馬達1 72的回轉停 止。因而，可防止在頂出具用伺服馬達丨72由制動裝置 7 4進行制動的狀態下，運轉繼續的情形。 如上述，在制動驅動電路，特別是在到制動裝置i 74 的配線產生斷線時，除了快速地以燈顯示之外，因為在 顯不部230顯示，所以操作者可快速地知道發生斷線。 ^ 另方面，相對於頂出具裝置，在進行洗淨等的維 濩時，需要驅動頂出具用支架馬達172，以作為突出頂出 /、銷(第1圖的卜1)的狀態。此狀態係以最大力矩Tp驅 ^頂出具用伺服馬彡1 72，將頂出具銷突出之後，使回轉 :止以制動裝i i 74進行的制動被得到。又，在此狀 ::口為制動裝置1 74係對於頂出具用伺服馬達1 72， - ：2大力矩TP以上的制動力矩Tb進行制動，所以回 设缽簧(第1圖的卜9)的偏壓力可防止頂出具銷返回。 制動羞置被作動期間，因為沒有必要供給用以使 二服馬達制動的電流供給，可防止因伺服馬達的過度發 於具備有由電磁制動 達172的頂出具裝置 又’雖然上述實施例係為適用 的制動裝置7041-6769-PF 30 1252155 Actuator 174 performs braking. At the same time, the second relay 222 is turned off by becoming non-excited, and its b-contact is closed. As a result, since the first relay 221 is in the open state and its a contact 221 is closed, in addition to the lighting of the lamp 226, the system is transmitted to the controller 200. The controller 2 stops the rotation of the ejector servo motor 1 72 via the servo driver 2 in addition to the display of the disconnection on the display unit 23A. Therefore, it is possible to prevent the operation from continuing when the ejector servo motor 丨 72 is braked by the brake device 74. As described above, in the brake drive circuit, particularly when the wiring to the brake device i 74 is broken, in addition to being quickly displayed as a lamp, since the display is displayed on the display portion 230, the operator can quickly know that the disconnection has occurred. . On the other hand, in the case of performing maintenance such as cleaning, it is necessary to drive the ejector bracket motor 172 as a state of protruding the ejector/pin (Fig. 1 of the first drawing). In this state, the servo head 1 72 is driven by the maximum torque Tp, and after the ejector pin is protruded, the rotation is performed: the braking by the brake device i i 74 is obtained. Further, in this case, the port is the brake device 1 74. The brake motor torque of the ejector servo motor 1 72, - : 2 is equal to or greater than the braking torque Tb of the large torque TP, so the spring is returned (Fig. 1). The biasing force prevents the ejector pin from returning. During the operation of the brake shyness, since it is not necessary to supply the current supply for braking the two-motor brake, it is possible to prevent the servo motor from being excessively generated by the ejector device having the electromagnetic brake up to 172, although the above embodiment is Applicable brake device
