    [48] Hereinafter, the operation of the pallet magazine setup station 90 degree index apparatus according to an embodiment of the present invention will be described.
    [49] First, when the rotation frame 20 is to be rotated, the plunger 53 of the clamping device 50 is operated to release the clamping state with the locating bush 51 to be unclamped, and the unclamping of the plunger 53 is performed. When the confirmation signal is received from the upper proximity switch 54a for the clamp, the hydraulic motor 60 is operated.
    [50] When the rotation of the hydraulic motor 60 is applied, the sprocket 61 mounted on the hydraulic motor 60 is rotated, the rotation frame 20 is rotated by the chain 62 is engaged with the sprocket 61.
    [51] If the deceleration proximity switch 66 recognizes the deceleration dogs 65a, 65b, 65c, 65d during the rotation of the rotation frame 20, the flow path of the hydraulic circuit is changed to the deceleration valve 86 so that the rotation frame 20 decelerates. At this time, the unclamping state of the clamping device 50 is released and the plunger 53 moves upward.
    [52] The plunger 53 slides on the lower surface of the rotation frame 20, and then the plunger 53 is inserted into the locating bush 51 formed below the rotation frame 20 in the setup position.
    [53] At this time, when the clamp confirmation signal of the proximity switch (54a, 54b) for the clamp is generated, the rotation of the hydraulic motor 60 is stopped and the clamp state is maintained to set the workpiece. Every 90 degrees, the workpiece can be set by repeating the unclamp or clamp state with the above operation.
    [54] The current position of the rotation frame 20 is recognized by the position sensing tags 63a, 63b, and 63c installed at the 0 °, 90 °, and 180 ° positions by the limit switches 64a and 64b, and the clamping device 50 is attached thereto. Can be detected by a combination of the clamp confirmation signals. For example, the current position is recognized as shown in Table 1 below.
    [55] Current position (angle; °)1st limit switch2nd limit switchProximity switch for clamp 0 °ONONON 90 °ONOFFON 180 °OFFONON 270 °OFFOFFON
    [56] That is, the first and second limit switches 64a and 64b and the clamp proximity switches 54a and 54b make contact with the respective dogs 63a, 63b, 63c, 65a, 65b, 65c and 65d as shown in the above table. In this case, the current position is 0 ° (origin), and the first and second limit switches 64a and 64b do not form a contact, and the current position when the clamp proximity switches 54a and 54b make a contact is 270 °. Recognize it as a state.
    [57] Hereinafter, the operation of the hydraulic motor and the operation of the clamp device as described above will be described through a circuit diagram.
    [58] First, when the rotation frame 20 is to be rotated, the fourth solenoid valve 84 is closed to block the inflow of the working fluid into the hydraulic motor 60, the second solenoid valve 90 is opened, and the working fluid is clamped. ) To overcome the spring force by the spring provided in the clamping device (50) and to lower the plunger 53 to release the clamping state, and the unclamping confirmation signal of the plunger (53) for the clamp upper proximity switch (54a) The controller received from the operating the hydraulic motor 60 to rotate the rotation frame 20. At this time, by adjusting the direction of the flow of the working fluid by adjusting the first solenoid valve 83, it is possible to select the rotation in the forward direction and the reverse direction of the rotation frame 20.
    [59] If the deceleration proximity switch 66 recognizes the deceleration dogs 65a, 65b, 65c, and 65d during the rotation of the rotation frame 20, the controller that receives the signal from the deceleration proximity switch 66 causes the bypass valve 85 to operate. By rotating the working fluid toward the deceleration valve 86 to reduce the rotation frame 20. At this time, the controller closes the second solenoid valve 90 and the third solenoid valve 95 is opened and air is injected. The plunger 53 moves upward by unclamping the clamping device 50.
    [60] At this time, when the clamp confirmation signal of the proximity switch 54a, 54b for the clamp is generated, the controller stops the inflow of the working fluid, the rotation of the hydraulic motor 60 is stopped, the clamp state is maintained, and the workpiece can be set. .
    [61] In the preferred embodiment of the present invention, but the sprocket and the chain is engaged to adopt a structure for transmitting power, the present invention is not limited to this, the pulley and the belt is installed by adopting a structure for transmitting power by the friction force of the pulley and the belt. It is also possible to transfer power using gears to the hydraulic motor and the rotation frame.
    [62] In a preferred embodiment of the present invention, a hydraulic motor is used as the driving means of the sprocket, but the present invention is not limited thereto, and it is also possible to use an electric motor.
    [63] In addition, in the preferred embodiment of the present invention, four deceleration dogs are used for deceleration of the rotation frame, but the present invention is not limited thereto, and four or more deceleration dogs may be used for more precise deceleration. Do.
    [64] Also, in the preferred embodiment of the present invention, two clamping proximity switches are used to detect whether the plunger is clamped. However, the present invention is not limited thereto, and one clamping proximity switch may be used.
    [65] According to the pallet magazine setup station 90 degree index apparatus according to an embodiment of the present invention having the above configuration, the operation of rotating the rotation frame is made automatically by using power rather than manual operation can reduce the labor of the operator .
    [66] In addition, since a series of processes such as the deceleration proximity switch detect the position of the rotation frame and cause the plunger to rise, the chain of signals is performed, so the working time is significantly shorter than when the operator checks the process. This can contribute to increased productivity.
    [67] Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
