Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gas filling packing method,

The present invention relates to a method of filling a large packaging bag with a packing material such as rice, sugar, pet food, or fertilizer weighing about 10 to 20 kg, The bag is continuously shaped from the filling of the bag mouth until the bag mouth is temporarily sealed so that the packing bag in the flat loading can be made into a desired stable form in which the drop water does not easily collapse , A gas filling packing method capable of automating the entire operation including switching of related apparatuses according to bag size change, and a packing machine thereof.

BACKGROUND ART [0002] In a conventional rotary type packaging machine, there is known a method of filling a package such as rice or sugar having a weight of about 1 kg to 15 kg and packaging the same. For example, Patent Document 1 of the present applicant discloses a packaging bag in which a rotary gas filled packing machine is used, and a packing bag filled with heavy articles of 10 kg to 15 kg by a pressing member provided with a vibrator is provided from both sides A packing method in which the bag material is pressed in a vertical direction to form a uniform thickness and at the same time air in the bag is removed by a deodorizing nozzle to perform heat sealing of the back mouse Lt; / RTI >

In the rotary type packaging machine, a grip for supporting the packaging bag is radially arranged on the rotating body and is rotationally moved, and a packaging bag filled with a package having a weight of 10 to 15 kg is interposed between stages A large centrifugal force is generated when the rotor is rotationally moved, resulting in a problem that a trace of a pinching portion due to the grip remains. Further, since the conventional shaping work is performed only at one stage, it is difficult to maintain stability in the shape after the shaping, and this is a factor that causes the dropping of the load to occur when the product after the packaging is laid flat.

In addition, the conveyor type bag feeder has a known structure in which the packing bag is laid and stacked on the belt conveyor, and is fed one by one from the front packaging bag to the grip of the packaging machine, In the case of a large packing bag of ~ 1050 mm, since the belt conveyor is long and requires a large space, when a chuck is formed, a slightly bulging chuck part is prevented from moving smoothly when it is fed forward on the belt conveyor . In addition, a conventional magazine-type bag feeding device has a structure for manually adjusting a guide for accommodating a packaging bag when changing the bag size, as shown in Patent Document 3, and is suitable for automaticization of the packaging machine Function is not provided. In addition, there were no suitable devices for large gusset bags, large stock chucked bag stocks or bags.

Further, with regard to the grip of the conventional packing machine, since the gripping portion for supporting the packing bag is manually adjusted in accordance with the bag width, it takes much time and effort .
