The present invention relates to a loading and unloading system of a molding press, and more particularly, a loading and unloading system of a molding press for loading a molding object into the molding press and unloading the molded molding after finishing molding. It is about.

In general, a plurality of molding presses (PCB Laminating hot press) for forming a variety of electronic components such as a printed circuit board is formed at a predetermined interval, and when the molding object such as a circuit board is seated therebetween to form the molding object at a constant temperature. It consists of a heat generating plate and cylinders laminated to each other by applying a constant pressure to the heat generating plate.

A loading and unloading system of a conventional molding press for loading a molding object between the heating plate and the heating plate, or unloading a molded product between the heating plate and the heating plate, includes a carrier plate on which the molding object or molding is seated, and A carrier plate latching device for hanging up a carrier plate, a carrier plate forward and backward device for advancing the carrier plate latching device back and forth a predetermined distance, and the carrier plate forward and backward device for reciprocating a predetermined section to a loading station / molding press / unloading station It is a structure provided with the carrier plate reciprocating feeder.

In particular, the carrier plate reciprocating device of the loading and unloading system of a conventional molding press is installed to enable reciprocation by a transfer rail installed on the ground or floor of a factory and wheels moving along the transfer rail. It is a structure comprised by the movement trolley and the said movement trolley, and the feed motor which drives the said wheel.

The type of the conventional carrier plate is a flange type in which both edges of the carrier plate body are bent like a plate to form a flange portion by bending, or a hole type in which a vertical hole is formed in the carrier plate body. The carrier plate locking device of the loading and unloading system of a conventional molding press, in the case of a flange type carrier plate, includes both arms for lifting the flange of the carrier plate and an arm lifting device for lifting the arms. In the case of a carrier plate of the hole type, the hook is inserted into the vertical hole of the carrier plate, a horizontal feed roller is installed to facilitate the sliding of the carrier plate caught in the hook and the hook forward and backward device for pulling the hook Configuration.

However, such a conventional molding press loading and unloading system, firstly, when the carrier plate of the flange type is applied, the processing precision in the production of the carrier plate to be processed by banding is greatly reduced, and for the bending process relatively There was a problem in that the precision of the product is deteriorated because the carrier plate is thinly twisted or bent easily, and when the hole-type carrier plate is applied, the processing accuracy of the carrier plate may be improved, but As the horizontal feed roller slides in contact with each other, there are many problems such as hot plate damage due to wear and friction of the carrier plate and the roller or additional installation cost of the roller during loading and unloading.

Second, various lifting devices such as arm lifting devices of the conventional loading press and unloading system use screw rods, belts and pulleys, and the device is unnecessarily enlarged despite the relatively short lifting distance. There was a problem of losing or complicated structure.

Third, in the conventional loading and unloading system of the molding press, the conveying rail is installed on the ground or the floor of the factory, and is separately installed apart from the molding press, so that the molding target or In order to load and unload moldings, the alignment work of connecting the molding press with the loading and unloading system is very cumbersome, and the conventional carrier plate reciprocating feeder is supported only by the lower rail so that the carrier plate is moved forward and backward. When the press enters, the device is inclined toward the forming press due to the load, and the alignment position of the forming press and the loading and unloading system are easily shifted, so that the parts collide with each other during the loading and unloading operation, or the conveying operation fails. There is a problem such as a bad It was.

An object of the present invention for solving the above problems is to improve the processing accuracy of the carrier plate by using a carrier plate of the ear type rather than the flange type or hole type, and to prevent deformation of the carrier plate or damage to the hot plate, The use of an eccentric rotary cam as a carrier plate lifting device simplifies the structure by minimizing the device.
