[0047] Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings. However, this is only exemplary, and the present disclosure is not limited to the specific embodiments exemplarily described.

[0048] The secondary battery reel storage rack 100 disclosed in the present invention is used to store reels wound with short-width semi-finished products in the secondary battery process. Figure 1 , the secondary battery reel storage rack 100 of the present disclosure includes a loading column 110 , a cantilever 120 , and a cover 130 .

[0049] The loading column 110 may be in the form of a rod or a bar vertically disposed on the ground ( Figure 1 xy plane, the same below) Figure 1 z-axis direction, the same below) is vertical.

[0050] The cantilever 120 is in the form of a beam horizontal to the ground (parallel to Figure 1 The cantilever 120 is used to support the secondary battery reel 10 loaded on the secondary battery reel storage rack 100.

[0051] The cantilever 120 may be disposed on a side surface of the loading column 110. The cantilever 120 is formed to protrude from the side surface in a direction horizontal to the ground. Figure 1 As a reference, the cantilever 120 may be formed to protrude in a direction horizontal to the ground (here, protrude in the y-axis direction) from one side of the loading column 110 erected perpendicular to the ground.

[0052] A plurality of cantilevers 120 may be provided at set intervals.

[0053] The cantilevers 120 may be disposed at predetermined intervals in a vertical direction on the same side of the loading column 110. This is to provide a plurality of cantilevers 120 on one loading column 110 to effectively store the secondary battery reel 10.

[0054] by Figure 1 As a reference, two cantilevers 120 are arranged on the loading column 110 at a set interval. The number of cantilevers 120 is not limited to Figure 1, may vary according to the height of the loading column 110 and the condition of the secondary battery storage warehouse where the secondary battery reel storage rack 100 is installed.

[0055] The set interval of the plurality of cantilevers 120 may vary according to the diameter of the secondary battery reel 10. Preferably, the interval of the plurality of cantilevers 120 is set larger than the diameter of the secondary battery reel 10 so that the loaded secondary battery reels 10 do not interfere with each other.

[0056] The cover 130 may be provided at a lower portion of the cantilever 120. The cover 130 is installed between the cantilever 120 and the cantilever 120. The cover 130 serves to receive foreign matter that may fall from the secondary battery reel 10 loaded on the cantilever 120 provided on the upper side.

[0057] The cover 130 may be disposed corresponding to the plurality of cantilevers 110 .

[0058] The cantilever 120 has a beam shape extending and protruding in the horizontal direction from the loading column 110. Figure 1 , the cantilever 120 is inserted into the core 11 of the secondary battery reel to support the secondary battery reel 10. In order to support the load of the secondary battery reel 10, the cantilever 120 may have a curved cross-sectional shape.

[0059] Next, we will refer to Figures 2 to 4 Various embodiments of the curved cross-sectional shape of the cantilever 120 are described.

[0060] Reference Figure 2 According to the first embodiment, the cross section of the cantilever 120 may have a cross-sectional shape in which both ends 122 of the cantilever are bent downward with the center line CL of the width as a reference. Figure 2 The cross section of the cantilever 120 in FIG. 1 may have a “∧” shape.

[0061] In this case, the cantilever 120 is Figure 1 The bending line 121 is formed in the y-axis direction of the secondary battery reel. The bending line 121 supports the core 11 of the secondary battery reel.

[0062] Reference Figure 3 According to the second embodiment, the cross section of the cantilever 120 may have a cross-sectional shape in which both ends 122 of the cantilever are bent upward with the center line CL of the width as a reference. Figure 3 The cross-section of the cantilever 120 in FIG. 1 may have a “∨” shape.

[0063] In this case, both end portions 122 of the cantilever support the core 11 of the secondary battery reel.

[0064] Reference Figure 4 According to the third embodiment, the cross section of the cantilever 120 may have a cross-sectional shape in which both ends 122 of the cantilever are bent downward. Figure 3 The cross section of the cantilever 120 in FIG. 1 may have a “∩” shape.

[0065] In this case, the cantilever 120 forms a pair of bending lines 123 formed along the length direction. (Here, the length direction is the distance from one end to the other end of the cantilever 120, that is, the length direction, with Figure 1 A pair of bending wires 123 supports the core 11 of the secondary battery reel.

[0066] Reference Figure 5 The secondary battery reel storage rack 100 may be provided in plurality to form a secondary battery reel storage warehouse 200. In the secondary battery reel storage warehouse 200, the plurality of secondary battery reel storage racks 100 may be arranged in rows and columns at set intervals.

[0067] Next, the fork 310 for inserting the core 11 of the secondary battery reel in the stacker 300 for unloading the secondary battery reel 10 from the secondary battery reel storage rack 100 or loading the secondary battery reel 10 to the secondary battery reel storage rack 100 will be described.

[0068] The stacker 300 is a crane for unloading or loading a load in the form of a reel, and is a known technique, so detailed description and illustration are omitted. Next, the fork 310 of the stacker 300 as a characteristic part will be described in detail.

[0069] The stacker 300 includes a fork 310 into which the core 11 of the secondary battery reel is inserted. A cross section of the fork 310 may have a curved cross-sectional shape to correspond to a cross-sectional shape of the cantilever 120 .

[0070] Reference Figures 6 to 8 According to the first embodiment, the cross section of the fork portion 310 may have a cross-sectional shape in which both end portions 311 of the fork portion are bent upward. Here, the cross section of the fork portion 310 may have a “∪” shape.

[0071] In this case, both ends 311 of the fork support the core 11 of the secondary battery reel. The width of the fork 310 may be greater than the width of the cantilever 120. Both ends 311 of the fork may support the core 11 of the secondary battery reel. This may prevent the fork 310 from interfering with the cantilever 120 when inserted into the core 11 of the secondary battery reel.

[0072] Figure 6 A case where the cross section of the cantilever 120 has a “∩” shape is shown. Figure 7 This is the case where the cross section of the cantilever 120 has a "∧" shape, Figure 8 This is the case where the cross section of the cantilever 120 has a “∨” shape.

[0073] Reference Fig. 9According to the second embodiment, the cross section of the fork 310 may have a cross-sectional shape in which both ends 311 of the fork are bent upward. Here, the cross section of the fork 310 may have a "∨" shape.

[0074] The width of the fork 310 is greater than the width of the cantilever 120 , and thus both end portions 311 of the fork support the core 11 of the secondary battery reel.

[0075] The secondary battery reel may be lifted upward while supporting the core 11 of the secondary battery reel by the fork 310 having the above-described cross-sectional shape without the fork 310 interfering with the cantilever 120 .

[0076] The above is only an example of applying the principles of the present disclosure, and other configurations may also be included without departing from the scope of the present invention.
