Pulleys 27a and 29a are fixed to one end of the rotation shaft of the horizontal electric motor 27 and the horizontal rotation shaft 29, respectively, and a timing belt 30 is stretched around the pulleys 27a and 29a.
[0015]
Further, a front U-shaped holder 31 is fixed to the other shaft end of the horizontal rotation shaft 29, and an inversion shaft 33 having an axis in a direction orthogonal to the axis of the horizontal rotation shaft 29 rotates. It is pivotally supported. A reversal electric motor 35 such as a servo motor constituting a second drive member having a pulley 35a attached to the rotating shaft is attached to the holder 31. A pulley 35a of the rotating shaft and a pulley 33a attached to the reversing shaft 33 are attached to the holder 31. The timing belt 37 is stretched.
[0016]
In addition to the above-described electric motor, an air motor can be used as a driving member for the horizontal attitude control member 21 and the reverse attitude control member 23.
[0017]
A chuck mounting member 39 is fixed to the reversing shaft 33, and the chuck 19 is fixed to the chuck mounting member 39. As a result, the chuck 19 is rotated in the horizontal direction as the horizontal electric motor 27 is driven, and is reversely rotated as the reverse electric motor 35 is driven.
[0018]
Next, the operation of the swivel type product take-out machine 1 configured as described above will be described.
First, the reverse electric motor 35 is driven to control the chuck 19 so that its molded product holding surface faces the molded product P held in the movable mold, and the horizontal electric motor 27 is driven to control the horizontal. The posture control device 21 is rotated in the horizontal direction so that the molded product holding surface is parallel to the held surface of the molded product P.
[0019]

Is operated to project the molded product P in the movable mold toward the chuck 19 to hold the molded product P on the chuck 19.
[0021]
Next, the front / rear drive member 11 is controlled to rotate backward to move the chuck 19 away from the movable mold, and then the swing drive member 13 is controlled to rotate backward to rotate the swing arm 15 in the clockwise direction shown in the figure. Then, the chuck 19 holding the molded product P is moved to the molded product release position outside the resin molding machine.
[0022]
In this state, the molded product P held by the chuck 19 by driving and controlling the horizontal electric motor 27 and the reverse electric motor 35, respectively, is disposed at the molded product release position, such as a carry-out conveyor, a carry-out shooter, and a stacking device. It faces the molded product placement surface in the carry-out device 36. (See Figure 4)
[0023]
In this state, the holding of the molded product P by the chuck 19 is released and transferred to the carry-out device 36 to complete the molded product take-out operation. Then, the horizontal electric motor 27 and the reverse electric motor 35 are driven and controlled, respectively. Is returned to the initial state described above, and is kept waiting until the next molded product is taken out.
[0024]
Although the chuck 19 is moved to the molded product release position as the turning arm 15 is turned, the horizontal electric motor 27 and the reverse electric motor 35 are driven to control the posture of the chuck 19, but the chuck holding the molded product P is controlled. The chuck 19 may be controlled by driving and controlling the horizontal electric motor 27 and the reverse electric motor 35 in the middle of turning at the timing when the pair 19 exits the pair of upper and lower tie bars 4. In the above description, the horizontal electric motor 27 and the reverse electric motor 35 are driven and controlled so that the molded product P held by the chuck 19 moved to the molded product release position faces the mounting surface of the carry-out device 36. Although the posture of the chuck 19 is controlled, the posture of the chuck 19 may be controlled so that the molded product holding surface of the chuck 19 faces the mating surface of the die when the chuck 19 enters between the opened molds.
[0025]
In the present embodiment, the molded product holding surface of the chuck 19 is held in the movable mold in the mold by attaching the chuck 19 to the tip of the revolving arm 15 that rotates at high speed via the attitude control device 17. It can be made to be relative to the surface to be held of the molded product P, and the holding failure can be prevented.
[0026]
Further, when the chuck 19 moves to the molded product release position or in the middle of turning when the tie bar 4 is pulled out, the molded product P can be made to be opposed to the molded product placement surface of the carry-out device 36. As a result, there is no need to provide a delivery device that enables delivery by changing the direction of the molded product P between the swivel type product take-out machine 1 and the carry-out device 36, thereby simplifying and reducing the molded product take-out system. Cost can be increased.
