BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a barrel door automatic opening /

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barrel door automatic opening and closing apparatus, and more particularly, to a barrel door automatic opening and closing apparatus for automatically opening and closing a door member of a barrel unit.

Plating generally refers to coating the surface of a metallic material with a thin film of another kind of metal or alloy.

Therefore, the main purpose of performing such plating is for a method (corrosion prevention), decoration, and surface treatment. For example, a thin film having a special function such as a magnetic thin film, a conductor thin film, a resistive thin film, and a superconducting thin film is used. The generalized plating method for coating such a film is electroplating, chemical plating, hot dip coating, spraying, Chemical vapor deposition and penetration plating.

Here, electroplating refers to a method of obtaining a coating layer by reducing and precipitating a target metal (a metal that becomes a direct thin film) present in the form of ions in an aqueous solution on the surface of the object to be plated with electrical energy. That is, a metal having a higher ionization energy than hydrogen or a metal having a high hydrogen overvoltage in an aqueous solution can be electrodeposited.

For example, in steel products, multilayer plating of copper-nickel-chromium that combines the corrosion (prevention of corrosion) and decoration, and single layer plating of zinc-cadmium-tin for decoration purposes are being conducted.

In addition, plating of noble metal such as gold-silver-palladium-rhodium may be performed for a copper alloy product or the like.

Specifically, the plating for imparting a special function includes a magnetic thin film such as a cobalt-phosphorus alloy or a cobalt-nickel alloy, a superconducting thin film such as a niobium tin alloy, a lead-bismuth alloy, a gold-titanium carbide, a gold- And a conductive and abrasion-resistant thin film.

In this case, in order to smoothly and uniformly coat small objects to be plated, such as bolts, nuts, and washers, a small number of objects to be plated are put into a rotatable barrel among plating apparatuses adopting the electroplating method, The plating solution is immersed in a plating solution containing a plating solution in which the metal is dissolved in the form of ions.

However, when the object to be plated with the barrel is charged, or when the object to be plated is discharged, the object is carried out by the automatic apparatus. However, as the operator performs the opening and closing of the barrel for performing such an operation, There is a problem that the door is damaged due to irregular force of the door, the door is contaminated due to the external seating of the detached door, and the plating product is defective due to the operator's mistake. In terms of productivity, The price of the product is rising.
