The present invention relates to an automatic molded product retrieval device that performs controlled operations.

[Prior art 1] A conventional molded product automatic take-out device includes, for example, a running frame supported movably in the longitudinal direction on a main body frame attached to a molding machine, and front and rear frames provided on the running frame. It is generally known that the device consists of a movably supported front-rear moving body and a vertical drive member that is installed on the front-rear moving body and moves a chuck member that holds a molded product in the vertical direction. In this type of molded product automatic take-out device, when taking out the molded product from the mold, the chuck member is placed in a vertical position facing the molded product in the mold, and the taken out molded product is placed in a predetermined position. When releasing the chuck member at the release position, for example, an attitude control member is provided to control the attitude of the chuck member so as to reverse the chuck member so that the molded product faces the conveying surface of the carry-out conveyor provided at the release position. It's there. (Problem to be solved by R Ming 1) However, the posture control members installed in the above-mentioned automatic molded product take-out device are a link mechanism or a reversing mechanism such as a toggle mechanism, a rotation mechanism such as a rotary actuator, etc. For example, after the chuck member is rotated and carried out by a rotating mechanism, the chuck member is inverted by a reversing mechanism to a state where the molded product can be released. The problem is that the posture control mechanism becomes complicated and increases in size and weight.For this reason, when the chuck member moves and stops, the inertia force becomes large and the chuck member vibrates greatly when stopped. In other words, if the chuck member vibrates significantly, it will not be possible to immediately move on to the next operation, which will prolong the ejection time, and in the worst case, the chuck member may come off from the molded product and become impossible to eject. The present invention was invented in order to solve the above-mentioned conventional drawbacks, and its purpose is to carry out unloading and posture control of a molded product in one operation. It is an object of the present invention to provide an automatic molded product take-out device that can shorten the molded product take-out time by reducing the size and weight of the periphery of the pick member, which is available in 171 locations. The purpose of this is to reduce the weight and size of the posture control member, and to provide an automatic molded product unloading device that can immediately move on to the next operation and significantly shorten the unloading time.

It is characterized by configuring an automatic product take-out device. [Operation of the invention] Since the present invention is configured as described above, the first and second
When the traveling body and the front and rear traveling bodies are moved to a predetermined take-out position by the driving member, the chuck member comes into contact with the molded product in the mold. At this time, since the rotating shaft is installed so as to extend downward at 45 degrees with respect to the horizontal direction, when the chuck member comes into contact with the molded product, the posture of the chuck member is controlled to be vertical. ing. When the molded product is held by the chuck member,
After the traveling body is moved by the first drive member as necessary, the chuck member is twisted and rotated toward the side opposite to the mold by the rotating shaft that rotates 180 degrees in the opposite direction, and the molding is continued. The posture is controlled so that the surface holding the item faces downward. As a result, the molded product can be carried out and its posture controlled by a single operation of rotating the rotary shaft.
