Description

Packaging System {Packaging System}

The present invention relates to a packaging system, and more specifically, to a packaging system that can easily and quickly package products while improving packaging reliability.

As industrialization and division of labor become more sophisticated, it is common for each component that makes up a finished product to be manufactured by a different business, and the producer of the finished product purchases each manufactured component to produce the finished product.

At this time, the above components must usually be completed in accordance with the specified delivery deadline and supplied to the producer of the finished product. Therefore, it can be said that compliance with delivery date is a very important matter in manufacturing and packaging the above components.

Meanwhile, various components that make up a finished product require various handling depending on their material, function, and properties. In particular, in the case of electronic devices, careful handling may be required due to the sensitivity and durability of the product. To this end, packaging of components typically requires additional processes depending on the characteristics of the components.

However, when additional processes are added, the packaging speed of components inevitably decreases. Therefore, it is very difficult to achieve both packaging speed and packaging quality in the production of components.

Accordingly, technologies have been introduced to ensure packaging quality while quickly packaging products that require specific handling.

Korean Patent Document No. 10-2090638 discloses a gas filling packaging method and a packaging machine that can effectively perform bag filling of packaged items into large packaging bags. Specifically, a gas filling packaging method and packaging machine for securing the quality of the packaged product by simultaneously filling and packaging the packaged product with an inert gas are disclosed.

However, there is a limitation that this type of packaging method and packaging machine can only be applied to bulk products such as rice, sugar, and pet food. In other words, the above prior literature does not suggest a method for effectively packaging products with a specific shape other than in bulk form.

Korean Patent Publication No. 10-2004-0049825 discloses an automated packaging method and system. Specifically, an automated packaging method and system is provided that allows accurate delivery of packaged cartons using various identifiers to track the shipping container and its filling with component contents.

However, these types of packaging methods and systems do not provide a way to reliably and effectively package products that require specific processing. In other words, the above prior literature also does not suggest a method for quickly and stably performing the packaging process, even when a specific process is added.

3. According to embodiments of the present invention Packaging System(1) Description of how this works

Hereinafter, with reference to FIGS. 17 and 18, the process in which the packaging system 1 according to an embodiment of the present invention is operated and packaging work for a product is performed will be described in detail.

The packaging system 1 according to an embodiment of the present invention performs packaging work on products supplied through the various components described above, and ultimately packages the products contained in the first box B1 or the second box B2. It can be processed in the form of a pack (P).

The operating sequence of the packaging system 1 described below will be understood with reference to the arrows shown in FIGS. 17 and 18.

First, products are supplied to the product supply unit 100. In one embodiment, the product may be a PCB board, etc. The product supplied to the product supply unit 100 is moved between the cushioning material supply unit 200 and the product bundle unit 300 through the first product line (L1) or the second product line (L2).

Cushioning material is supplied to the cushioning material supply unit 200. The cushioning material loaded in the cushioning material loading unit 210 is transferred to the space where the product is located by the cushioning material transfer unit 220 and the cushioning material handle unit 230, that is, the space between the cushioning material supply unit 200 and the product bundle unit 300 described above. It is moved.

At this time, the product and the cushioning material may be stacked randomly or alternately, or the cushioning material may be stacked in a form that surrounds the lower and upper sides of the product.

The laminated structure of the product and the cushioning material is moved to the product bundle unit 300. At this time, the laminated structure may be moved through a conveyor belt system or the like. The product bundle unit 300 bundles (i.e., ties) the passed laminated structure using a string made of synthetic resin. Accordingly, the product and cushioning material may be in the form of a kind of pile.

The product and cushioning material that pass through the product bundle unit 300 proceed toward the product packing unit 400. The product packing unit 400 opens the previously accommodated first packing sheet (P1) or the second packing sheet (P2), accommodates the product and the cushioning material, and then seals it. At this time, in order to prevent oxidation of the product and the cushioning material, the product packing unit 400 may perform a process of suctioning the air inside the first packing sheet (P1) or the second packing sheet (P2). .

Accordingly, the work at the front end 10 is completed, and the product is converted into a product pack P. The product pack (P) is moved to the rear end (20) through the connecting rail (33) of the compartment wall (30).

The product pack P moved to the rear end 20 reaches the package folding unit 500. The package folding unit 500 presses or hits the wing portion of the product pack (P) to deform the shape of the product pack (P) so that it does not protrude to the outside. Accordingly, the product pack P that has passed through the package folding unit 500 may be transformed into a smooth square pillar shape.

The product pack P on which the folding operation has been completed is moved toward the box packing unit 800 and is positioned between the first box supply unit 700a and the second box supply unit 700b.

The air cap supply unit 600 cuts the supplied roll-shaped air cap (A), injects air into the space where the product pack (P) is located, that is, the first box supply unit (700a) and the second box. It is moved between the supply units (700b).

The first box supply unit 700a and the second box supply unit 700b operate independently to collect the first box B1 and the second box B2, respectively. The packed first box (B1) and second box (B2) are moved between the first box supply unit (700a) and the second box supply unit (700b).

Therefore, the product pack (P), air cap (A), first box (B1), and second box (B2) can all be located between the first box supply unit (700a) and the second box supply unit (700b). .

The first spacer (G1) or the second spacer (G2) is accommodated inside the first box (B1) and the second box (B2) for which the boxing operation has been completed by the lower spacer supply unit 730. Next, the product pack (P) and the air cap (A) are accommodated inside the first box (B1) and the second box (B2), and the first gap member (G1) is supplied by the upper gap member supply unit 740. Alternatively, the second spacing member (G2) is accommodated on the upper side of the product pack (P) and the air cap (A).

Accordingly, the interior of the first box (B1) and the second box (B2) includes a spacer (i.e., a lower spacer), a product pack (P), an air cap (A), and a spacer (i.e., an upper spacer). can be stacked and accommodated. As a result, the product pack P accommodated in the first box B1 and the second box B2 is not damaged by external impact.

The first box (B1) and the second box (B2) for which the receiving operation has been completed, that is, the first box (B1) and the second box (B2) in which the product pack (P) is accommodated, are transported by the box packing unit 800. It is packed. In one embodiment, the box packing unit 800 tapes the upper sides of the transported first box (B1) and the second box (B2) in a plurality of directions to form the first box (B1) and the second box (B2). Can be packed.

The first box (B1) and the second box (B2) transported by the box packing unit 800 are labeled for identification by the labeling unit 900 and then placed in the first stack 920 or the second stack. Accepted at (930). The received first box (B1) or second box (B2) may be supplied to the consumer using an operator or any device.
