Description

Packing Device and Method for Guardrail The present invention relates to a packaging device and method, and more specifically, to a handrail packaging device and method for packaging handrails. Handrails refer to facilities installed on balconies, roads, stairs, bridges, etc., of residential facilities to prevent safety accidents by interfering with movement between spaces. Recently, handrails are sometimes manufactured using materials such as glass or transparent plastic for aesthetic purposes or to ensure visibility, but most handrails intended for safety are manufactured using metal materials of the same weight as steel to resist external forces. Meanwhile, handrails manufactured in factories or similar facilities must be transported to the actual construction site, and they are generally packaged to prevent damage during transport. Conventional handrail packaging involves placing a vinyl packaging material around the handrail and then joining the edges of the packaging material by heat fusion. However, when packaging handrails using this conventional technology, a portion of the packaging material fuses to the handrail during the heat fusion process, causing the handrail to become contaminated. Furthermore, there is a risk that the handrail may be directly damaged by the heat applied for the heat fusion of the packaging material. FIG. 1 is a plan view showing a handrail paving device according to an embodiment of the present invention. FIG. 2 is a plan view showing the state in which a railing and a wrapping paper are arranged in an embodiment of the present invention. FIG. 3 is a schematic diagram showing an embodiment of the present invention. FIG. 4 is a flowchart schematically showing a handrail paving method according to an embodiment of the present invention. Hereinafter, a handrail paving device according to an embodiment of the present invention will be described in more detail with reference to the attached drawings. FIG. 1 is a plan view showing a railing paving device according to an embodiment of the present invention, FIG. 2 is a plan view showing a state in which a railing and paving paper are arranged in an embodiment of the present invention, and FIG. 3 is a schematic diagram showing an embodiment of the present invention. Referring to FIGS. 1 to 3, the railing packaging device (1) according to the present embodiment packages a railing (G) in a packaging sheet (P). Here, the railing (G) may be a railing made of steel or other metal material primarily used for safety purposes, and the packaging sheet (P) may be made of a material that ensures a certain level of strength and surface roughness, such as non-woven fabric or woven fabric. In the railing packaging device (1), the packaging sheet (P) is formed in a rectangular shape and folded along a symmetry axis so that its edges are positioned on the same straight line, and the railing (G) is placed inside the packaging sheet (P), that is, between two sides of the folded packaging sheet (P). The railing packaging device (1) includes a base unit (100), a fixing unit (200), a sensing unit (300), a conveying unit (400), a sewing unit (500), and a control unit (600). More specifically, the base unit (100) is a place on its upper surface where the railing (G), substantially the railing (G) positioned inside the packaging (P), is placed. In particular, in this embodiment, a railing position area (A1) and a packaging position area (A2) are defined on the upper surface of the base unit (100). Here, the railing position area (A1) and the packaging position area (A2) are virtual areas defined on the upper surface of the base unit (100). The packaging position area (A2) is an area where the packaging (P) is positioned so that its edges are suitable for sewing by the sewing unit (500), as will be described later. The railing position area (A1) refers to an area where the railing (G) is positioned so that a sufficient buffer space can be secured between the edges of the packaging (P) and the edges when the edges of the packaging (P) are sewn. Accordingly, the railing position area (A1) and the packaging position area (A2) will be defined differently depending on the type and size of the railing (G) and the packaging (P). Additionally, the border of the packaging location area (A2) is defined to be spaced apart from the upper surface border of the base unit (100), and the border of the railing location area (A1) is defined inside the packaging location area (A2) to be spaced apart from the border of the packaging location area (A2). At this time, for example, the railing location area (A1) may be located on the border line of the packaging (P), or on the inside or outside thereof. Next, the fixing unit (200) fixes the two sides of the packaging (P) so as to restrict relative movement. For example, the fixing unit (200) may restrict relative movement of the two sides of the packaging (P) by being positioned on both sides centered on the two sides of the pa
