Description

Description: TECHNICAL FIELD The present invention relates to a transfer device for a molded component storage container by a resin molding machine, and particularly in unmanned molding work at night, computer-related components or other electronic devices. Synthetic resin molded parts used as parts are molded with a synthetic resin molding machine, and these molded parts are stored in a container from a relatively low position delivery part of the molding machine, and after a certain period of time passes or a certain quantity is reached. By automatically moving the container and moving the next container to the delivery site, it was possible to automatically and continuously convey the container containing the mass-produced molded parts to the target location. It is a thing.

[Prior Art] Generally, a part molded by a resin molding machine is delivered from a delivery site of the molding machine, accommodated in a predetermined amount in a storage container, and transported to a target location. And as the above-mentioned transportation method, there are a case of using a human power and a case of using a known belt conveyor. In this case, it is possible to repeatedly move and stop the belt conveyor drive source with a timer or the like at regular intervals.

[Problems to be solved by the invention]

However, among the above-mentioned transportation methods, when the human power is used, the continuous molding work by unmanning for a long time such as day and night requires human power to transport the molded parts. It is not preferable because the cost becomes high.

On the other hand, the method of transporting with a belt conveyor is suitable for unmanned work at night, but when a container placed on a belt is repeatedly moved and stopped according to the time setting by the function of a timer, etc. Since the container is pushed, there is a slight discrepancy in the control of the direction of each container and the size of the container and the movement amount of the belt conveyor, and the position of the container is misaligned each time the belt conveyor is repeatedly driven and stopped. Therefore, if the unmanned driving state continues for a long time due to continuous molding processing at night, there is a risk of causing an unexpected accident. In addition, the parts delivery site of the generator for computer-related parts or other electronic device parts is located at a relatively low position of about 60 to 70 cm from the floor surface, whereas in the known belt conveyor machine, the belt surface to be conveyed is on the floor. Since it is relatively high from 60 to 90 cm, it is positioned as it is at the part delivery site of the resin molding machine, and when a container with a height of about 30 to 40 cm is placed, the height is at least about 90 cm. Therefore, it is difficult to apply it to the conveyance by the molding machine.

[Means for solving problems]

Therefore, the present invention solves the problems of the conventional conveying apparatus, and automatically and continuously forms a container containing a synthetic resin molded part used as a computer and other electronic device-related parts, molded by a resin molding machine, every predetermined time. An object of the present invention is to make it possible to convey the material toward a predetermined location even during unmanned forming work such as nighttime by repeating movement and stop.

In order to achieve the above object, the present invention provides a pair of left and right rail bodies in which a plurality of free rollers are arranged in a row, and a constant width of the rail body in a conveying device for a molded component storage container by a resin molding machine. An endless chain belt mechanism (3) having a machine frame to be fixed, a pair of front and rear pulleys arranged along the length between the rail bodies, and a pusher that winds around the pair of front and rear pulleys and pushes a container. A molded component storage container having a guide (8) extending along the outside or the inside of the rail member and placed on the rail member, and the container stops facing the molded component delivery site of the resin molding machine (10). And, the molded parts that are continuously produced within a predetermined time are containers (7).
When a predetermined amount is stored in the container, a detection mechanism (9) for moving and stopping only one container and its actuation on / off mechanism (12), and a machine frame (2) with the rail body (1) fixed It is composed of a wheel that is movable and adjustable.

[Action]

The operation based on the above means will be described. First, the rail body is disposed at a position orthogonal to the delivery site of the resin forming machine, and the rail body is disposed at a substantially middle portion of its entire length.

Next, the formed component storage container is placed on the rail body and the advancing / retreating mechanism that face the delivery site, and the same containers as the above-mentioned containers are sequentially placed in a row at the rear of the container in the same direction. The detection mechanism for driving / stopping the advancing / retreating mechanism and the actuation on / off mechanism use a timer and a microswitch or a relay circuit or the like, and these are operated in conjunction with each other.

Then, the operation of the resin molding mechanism is started. The molded part is placed from the delivery site of the molding machine into a container that faces the delivery site and is not placed on the rail.

Next, the advancing / retreating mechanism moves by the function of the detection mechanism set at a predetermined time and the lower part of the rear surface of the container is pushed by the pusher, so that the container moves by one and the next empty container faces the delivery site. The process is stopped at the position to be completed and one process is completed. The timer is set by a resin molding machine so as to set a time required for a molded part to be put into a container from a delivery site and to reach a desired quantity.
