[0030] The base plate (10), marker plate (20), and cover plate may be made of metal plates, for example. The base plate (10), marker plate (20), and cover plate may have a roughly square plate shape. The base plate (10), marker plate (20), and cover plate may be manufactured in the same shape as each other.
[0031] The base plate (10) is a part that is attached by making contact with the floor surface of the industrial site. In industrial sites such as logistics centers, rapid receiving and shipping of goods is vital, so to increase competitiveness, unmanned automation systems are introduced and robots are used more extensively in places where it is difficult to work with human labor, thereby saving labor costs and increasing work efficiency and productivity. One of the pieces of equipment widely used in such automation systems is the AGV (Automated Guided Vehicle). Recently, AGVs are being widely used in fields that handle large volumes of products, such as logistics centers. The base plate (10) is a part that is directly attached to the floor surface of the industrial site.
[0032] As described above, the base plate (10) may be made of a square metal plate. A first fastening hole (12) for fastening to a bottom surface may be formed at the corner portion of the base plate (10), but is not limited thereto, and the base plate (10) may be attached to a bottom surface without the first fastening hole (12). The first fastening hole (12) is formed to correspond to the second fastening hole (22) and the third fastening hole (42) described below, and can be fastened to a bottom surface using a fastener such as a screw.
[0033] Additionally, a first position alignment section (14) for position alignment on the bottom surface may be formed on each of the four sides of the base plate (10). The first position alignment section (14) is a part provided for alignment with a line drawn on the bottom surface when setting the alignment position of the base plate (10). The first position alignment section (14) may be formed by being recessed into a triangular cross-section, for example.
[0034] In one embodiment, the base plate (10) may be formed in white or silver. Here, the term "white" may be applied to any color that can be contrasted with black, in addition to the white defined in the dictionary.
[0035] Referring to FIG. 2, the marker plate (20) is a part attached to the surface of the base plate (10). As described above, the marker plate (20) may be made of a square metal plate. A second fastening hole (22) for fastening to the bottom surface may be formed at the corner of the marker plate (20), but is not limited thereto, and the marker plate (20) may be attached to the bottom surface without the second fastening hole (22). The second fastening hole (22) is formed to correspond to the first fastening hole (12) and the third fastening hole (42), and can be fastened to the bottom surface using a fastener such as a piece.
[0036] Additionally, a second position alignment section (24) for position alignment on the bottom surface may be formed on each of the four sides of the marker plate (20). The second position alignment section (24) is a part provided for alignment with a line drawn on the bottom surface when setting the alignment position of the marker plate (20). The second position alignment section (24) may be formed by being recessed into a triangular cross-section, for example.
[0037] In one embodiment, the marker plate (20) may be formed in black. Here, the term "black" may be applied as any color that can be contrasted with white or silver, in addition to the black defined in the dictionary.
[0038] Additionally, a second position alignment section (24) for position alignment on the bottom surface may be formed on each of the four sides of the marker plate (20). The second position alignment section (24) is a part provided for alignment with a line drawn on the bottom surface when setting the alignment position of the marker plate (20). The second position alignment section (24) may be formed by being recessed into a triangular cross-section, for example.
[0039] A through-hole (26) is formed through the central part of the marker plate (20). The through-hole (26) is a part formed to form a marking part (30) for guiding the driving path of the AGV. That is, the through-hole (26) is formed to form the shape of the marking part (30) that is finally displayed on the marker assembly, and a base plate (10) formed in white is exposed through the through-hole (26). Thus, the marking part (30) can be displayed in the required shape in contrast to the marker plate (20) formed in black. The through-hole (26) can be formed in the required shape on the inner side of the marking part (30).
[0040] The marking portion (30) is a part that the AGV actually recognizes on the driving path, and can be displayed in black when finally manufactured. The marking portion (30) is indicated by a dotted line in FIG. 2, and can be displayed externally when the cover plate (40) is finally attached.
[0041] Referring to FIG. 3, the cover plate (40) is a part attached to the surface of the marker plate (20). As described above, the cover plate (40) may be made of a square metal plate. A fourth fastening hole (42) for fastening to the bottom surface may be formed at the corner of the cover plate (40), but is not limited thereto, and the cover plate (40) may be attached to the bottom surface without the third fastening hole (42). The third fastening hole (42) is formed to correspond to the first fastening hole (12) and the second fastening hole (22), and can be fastened to the bottom surface using a fastener such as a screw.
[0042] Additionally, a third position alignment part (44) for position alignment on the bottom surface may be formed on each of the four sides of the cover plate (40). The third position alignment part (44) is a part provided for alignment with a line drawn on the bottom surface when setting the alignment position of the cover plate (40). The third position alignment part (44) may be formed by being recessed into a triangular cross-section, for example.
[0043] In one embodiment, the cover plate (40) may be formed in white or silver. Here, white refers to any color that can be contrasted with black. The cover plate (40) is formed in black to contrast with the marker plate (20) formed in black, so that when it is finally attached, the black marking portion (30) can be displayed externally.
[0044] To this end, a marker window (50) is formed through the central part of the cover plate (40). The marker window (50) may be formed to have an area larger than the through-hole (26) and is formed to cover the outside of the through-hole (26) so that the marking part (30) can be substantially exposed to the outside. In one embodiment, the marker window (50) may have a square shape.
[0045] Referring to FIGS. 4 and 5, the marker assembly can be attached in the order of a base plate (10), a marker plate (20), and a cover plate (40). That is, the marker plate (20) can be attached to the surface of the base plate (10), and the cover plate (40) can be attached to the surface of the marker plate (20) in sequence. When the three plates are attached in this way, the marking portion (30) can be exposed to the outside through the marker window (50) as shown in FIG. 5. Also, since the base plate (10) attached to the bottom is white or silver, the white or silver color is exposed through the penetration portion (26), so it can be clearly displayed to the outside in contrast to the black marking portion (30).
[0046] Additionally, a clear layer may be applied to the penetration portion (26) while the cover plate (40) is attached. For example, a transparent clear layer may be applied, and the layer may be applied to the thickness of the penetration portion (26). When the clear layer is applied in this manner, the marking portion (30) can be protected from being directly exposed to the outside through the penetration portion (26).
[0047] FIG. 6 is a drawing illustrating the attachment relationship of a marker assembly according to another embodiment of the present invention. In this embodiment, the same reference numerals have been assigned to components identical to those in the above-described embodiment, and a detailed description thereof is omitted for convenience.
[0048] A marker assembly according to another embodiment of the present invention as described herein comprises a base plate (10) and a marker plate (20) attached to the surface of the base plate (10) and having a through-hole (26) formed therein to form a marking portion for recognizing a driving path, and a coating portion (60) may be formed on the surface of the marker plate (20) to surround a marking portion (30) formed around the through-hole (26).
[0049] In this embodiment, the cover plate (40) disclosed in the above-described embodiment may not be included, and only the base plate (10) and marker plate (20) may be included.
[0050] Here, in addition to the penetration portion (26), a coating portion (60) forming a marking portion (30) may be formed on the marker plate (20). The coating portion (60) may be applied, for example, through a white or silver paint. That is, in this embodiment, the coating portion (60) is configured to perform the role of the cover plate (40) without the cover plate (40). When a coating portion (60) having a color or silver color is formed on the marker plate (20) in this way, the marking portion (30) can be clearly displayed to the outside in contrast to the black marking portion (30).
[0051] As seen above, since the marker assembly is formed by combining two or more plates, only the damaged plate can be separated and repainted for use. In addition, since the base plate (10) attached directly to the floor surface is less likely to be damaged, the position of the marker assembly can be prevented from shifting when reattached. Furthermore, since the possibility of the AGV deviating from its driving path can be reduced, safety can be ensured during the movement of the AGV.
[0052] Although the present invention has been described above with reference to specific embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims.
