However, this is not intended to limit the present invention to a specific disclosed form, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention. Throughout the description of each drawing, similar reference numerals have been used to designate similar components.

[0026] The above terms are used solely to distinguish one component from another. The terms used in this application are used solely to describe specific embodiments and are not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0028] Figure 1 is an internal perspective view of a cargo storage tower according to the present invention.

[0029] Referring to Fig. 1, a cargo storage tower (10) according to an embodiment of the present invention has an octagonal prism-shaped exterior. The cargo storage tower (10) is covered by an outer plate (not shown).

[0030] A cargo loading port (340) capable of storing cargo is formed on one side of the cargo storage tower (10), and a cargo loading opening (not shown) is formed on the front of the cargo loading port (340). The cargo loading opening may be formed to be openable by having a transparent door or the like.

[0031] In addition, the cargo storage tower (10) is provided with a touchscreen type operation panel (30) on the exterior surface for use by users when storing and receiving cargo. The opening of the cargo loading opening door can be controlled by a control unit (600) according to operations on the operation panel.

[0032] A cargo storage tower (10) includes a tray (100) capable of loading parcel cargo, a tray frame (200) capable of loading a plurality of trays (100), an outer tray tower (300) and an inner tray tower (400) in the form of polygonal columns forming the side portions of the tray frame (200), a tray transport tower (500) for transporting the tray (100), and a control unit (600). Cargo (P) is loaded onto the upper surface of the tray (100).

[0033] The cargo storage tower (10) according to the present invention includes an N-shaped column-shaped external tray tower (300). According to an embodiment of the present invention, the external tray tower (300) has an octagonal column-shaped shape with eight sides. Therefore, the cargo storage tower (10) according to the embodiment of the present invention has an octagonal column-shaped exterior due to the external tray tower (300).

[0034] An inner tray tower (400) is arranged inside an outer tray tower (300), and a transfer tower (500) is arranged inside the inner tray tower (400). According to the present invention, the inner tray tower (400) has a smaller M-shaped column shape than the outer tray tower (300) (M <N, M은 3이상). 본 발명의 실시예에 의하면, 내측 트레이 타워(400)는 오각 기동 형태를 갖는다.

[0035] According to an embodiment of the present invention, the side portion of the outer tray tower (300) and the side portion of the inner tray (400) are formed as a tray frame (200) for loading and unloading the tray (100).

[0036] Fig. 2 is a perspective view of a tray frame according to an embodiment of the present invention. The tray frame (200) illustrated in Fig. 2 forms side portions of the outer tray tower (300) and the inner tray tower (400) and forms a loading portion.

[0037] The tray frame (200) includes two facing side frames (220). Each side frame (220) may be formed of two vertical bars (222). Additionally, the side frames (220) may be formed of plates. The vertical bars (222) are vertically fixed between the upper fixed frame (212) and the lower fixed frame (214) to form the side frames (220).

[0038] The upper fixed frame (212) and the lower fixed frame (214) are formed in a shape having an angle between the side portions of the polygonal pillars. The upper and lower fixed frames (212, 214) form a common support for each side frame (220) of the adjacent tray frame (200).

[0039] Accordingly, the side frames (220) of two tray frames (200) adjacent to the upper and lower fixed frames (212, 214) can be arranged. For example, the side frame indicated by the drawing reference numeral 220-1 in FIG. 3 is the side frame of the adjacent tray frame (200).

[0040] On the inner surface of the side frame (220), a tray rail (230) is arranged to guide the tray (100) in a horizontal direction. The tray rail (230) is arranged in the intersecting direction of the side frame (220), i.e., in the horizontal direction, and a plurality of tray rails are arranged in the extending direction of the side frame (220), i.e., in the vertical direction. The tray (100) is loaded on the tray rail (230).

[0041] The tray rails (230) are positioned facing each other on the facing side frames (220). When a tray (100) is pushed between the side frames (220) along the tray rails (230), the side end of the tray (100) is guided by the tray rails (230) and moves horizontally to be loaded. In addition, when the tray (100) is pulled, the tray (100) is pulled outward from the tray frame (200) along the tray rails (230).

[0042] At the end of the tray rail (230) opposite to the insertion direction of the tray (100), a limit (235) is provided to prevent the tray (100) from being transported beyond the tray rail (230). The limit (235) may be, for example, in the form of a block that blocks the end of the tray rail (230). Additionally, it may be a plate attached to the end of the tray rail (230). Through this, the tray (100) is prevented from moving past the loading position in each tray frame (200).

[0043] Referring again to FIG. 1, each side portion of the outer tray tower (300) is placed on an octagonal base (310). A tray frame (200) is placed on the edge of the base (310) to form the side portion of the outer tray tower (300). The base (310) may be formed by a plate or by placing a plurality of bar members.

[0044] The outer tray tower (300) includes one cargo inlet frame (201). Therefore, according to an embodiment of the present invention, the octagonal prism-shaped outer tray tower (300) includes seven tray frames (200) and one cargo inlet frame (201). That is, when the outer tray tower (300) is in the N-angle prism shape, it includes N-1 tray frames (200) and one cargo inlet frame (201).

[0045] The cargo inlet frame (201) includes two side frames (220) that face each other, similar to the tray frame (200). The cargo inlet frame (201) and the tray frame (200) have the same width and height, and share the upper and lower fixed frames (212, 214) of the adjacent tray frame (200). As a result, the outer tray tower (300) has regular polygonal, for example, regular octagonal columns.

[0046] FIG. 3 is a drawing for explaining a cargo inlet according to an embodiment of the present invention.

[0047] The cargo loading port (340) includes a cargo storage room (342) into which cargo is loaded and stored. The cargo storage room (342) is formed as a space capable of accommodating cargo loaded through the cargo loading opening.

[0048] A load cell mounting part (345) equipped with a load cell (344) is placed on the floor of the cargo storage room (342), and a tray (100) is placed on top of it. The weight of cargo loaded into the cargo input port (340) is measured using the load cell (344).

[0049] When sending parcels using the cargo storage tower (10) according to the present invention, the delivery fee can be calculated using the weight measured by the load cell (344). Furthermore, the cargo storage tower (10) can be programmed to only accept cargo below an appropriate weight to ensure stable operation of the device. Accordingly, cargo storage can be refused if the cargo exceeds the set weight limit.

[0050] The cargo inlet (340) includes a moving opening (343) formed at the rear side of the cargo storage compartment (342). The moving opening (343) forms a path along which the tray (100) moves rearward.

[0051] The cargo loading port (340) includes a height measurement sensor (347) on the side of the cargo storage compartment (342).

[0052] The height measurement sensor (347) measures the height of cargo (P) placed on a tray (100) in the cargo storage room (342). The control unit (600) sets the limit height of cargo that can be stored based on the spacing between the tray rails (230) on the tray frame (200). If the height of the cargo measured by the height measurement sensor (347) is higher than the limit height, cargo storage is rejected.

[0053] FIG. 4 is a perspective view of an inner tray tower of a cargo storage tower according to the present invention, and FIG. 5 is a drawing showing the lower surface of a cargo storage tower according to the present invention.

[0054] Referring to FIGS. 4 and 5, the inner tray tower (400) is arranged inside the outer tray tower (300). The inner tray tower (400) has a polygonal column shape in which a plurality of tray frames (200) are arranged to form the side portions of the M-shaped column. According to an embodiment of the present invention, the outer tray tower (300) has a regular octagonal column shape, and the inner tray tower (400) has a regular pentagonal column shape.

[0055] According to an embodiment of the present invention, the side portion of the inner tray tower (400) is formed with the same tray frame (200) as the side portion of the outer tray tower (300). The structure, size, and arrangement of the trail rails (230) of the tray frame (200) are the same. Since the side portions of the outer tray tower (300) and the inner tray tower (400) are formed with the same tray frame (200), the inner tray tower (400) has a smaller M-shaped column shape than the outer tray tower (300).

[0056] The cargo storage tower (10) according to the present invention is easy to manufacture and can ensure uniformity of each loading space by manufacturing the outer and inner tray towers (300, 400) by commonly using the tray frame (200).

[0057] It includes four side sections formed by a tray frame (200) of an inner tray tower (400) in the shape of a pentagonal polygonal column and one tray guide frame (202) used for a tray transport path. The tray guide frame (202) forms a path along which a tray (100) is transported toward the side section of the outer tray tower (300) when no trays are loaded.

[0058] The tray guide frame (202) can be formed with the same structure as the tray frame (200) on which the tray (100) is loaded, except that the limit (235) is omitted. Accordingly, it includes two side frames (220) facing each other and a plurality of tray rails (230) arranged in a direction intersecting each side frame (220).

[0059] Since the limit (235) is not placed, the tray (100) can be transported to the side of the outer tray tower (300) by passing through the tray guide frame (202) while being guided by the tray rail (230) of the tray guide frame (202). In addition, transport of the tray (100) in the opposite direction is guided.

[0060] The cargo storage tower (10) of the present invention includes a base (310), a rotation guide (410), and a rotation stage (510) at the lower part.

[0061] The rotation guide (410) is formed in a ring shape and is placed on the base (310). The rotation stage (510) is placed on the base (310) on the inside of the rotation guide (410).

[0062] The inner tray tower (400) is placed on a rotation guide (410) and is rotatably placed relative to the outer tray tower (300).

[0063] A tray frame (200) forming an inner tray tower (400) is arranged on a rotation guide (410) to form side portions, and a tray guide frame (202) is arranged on one side portion to form a pentagonal column shape. The inner tray tower (400) rotates inside the outer tray tower (300) by the rotation guide (410).

[0064] The rotation guide (410) includes an annular track plate (412) arranged on a base, and an annular rotary plate (414) that moves along the track plate (412). A roller (415) is provided on the lower surface of the rotary plate (414) to move along a guide formed on the track plate (412). A rotary guide motor (not shown) that drives the rotary plate (414) of the rotation guide (410) is arranged on the base (310). The rotary guide motor rotates the rotary plate (414) using a driving mechanism such as a belt or gear meshing. A guide roller (416) that rotatably supports the outer surface of the rotary plate (414) and supports the rotational position of the rotary plate (414) is provided on the base (310). Three or more guide rollers (416) are arranged at equal intervals to guide the rotation of the rotary plate (414) and prevent it from coming off.

[0065] The inner tray tower (400) includes a rotation support member (450) on the upper surface. The rotation support member (450) includes a support member (452) and a hub (455).

[0066] The support member (452) extends radially toward the center from the upper member (205) of the tray frame (200) of the inner tray tower (400) and is coupled to the hub (455).

[0067] The hub (455) is located at the upper center of the inner tray tower (400) and each support member (452) is connected. Axial portions (456) are formed on both upper and lower sides of the hub (455). The axial portion (456) may be formed as a protruding shaft or may be a shaft groove into which the shaft is inserted. When the axial portion (456) is formed as a protruding shaft, a shaft groove is formed at the portion where the shaft is coupled to the axial portion (456), and when the axial portion (456) is formed as a shaft groove, a protruding shaft is formed at the portion where the shaft is coupled. Hereinafter, the shaft portion (456) formed on the lower side of the hub (455) is formed as a shaft groove, and the shaft portion (456) formed on the upper side of the hub (455) is formed as a shaft groove, as an example, will be described.

[0068] The shaft portion (456) in the form of an axial groove formed on the lower surface of the hub (455) is rotatably coupled with the protruding shaft-shaped coupling shaft portion (523) on the upper surface of the tray transfer tower (500) arranged inside the inner tray tower (400) to support the rotation of the tray transfer tower (500). The protruding shaft-shaped shaft portion (456) formed on the upper surface of the hub (455) is rotatably supported on the upper surface (not shown) of the cargo storage tower (10).

[0069] Figure 6 is a perspective view of a tray transfer tower according to an embodiment of the present invention.

[0070] The tray transfer tower (500) includes a transfer frame (520) fixed on a rotation stage (510).

[0071] The transport frame (520) includes a top frame (522), a bottom frame (524), and side support frames (530) on both sides.

[0072] The top frame (522) is rotatably supported on the hub (455) of the inner tray tower (400). It includes a protruding shaft-shaped coupling shaft portion (523) that is rotatably supported by an axial groove-shaped shaft portion (456) formed in the lower direction of the hub (455).

[0073] The lower frame portion (524) is placed on the base (310) and is coupled to a rotation stage (510) that rotates. Accordingly, the transfer frame (520) is rotated by the rotation stage (510).

[0074] The side support frame (530) is arranged on both sides between the top frame (522) and the bottom frame (524). The side support frame (530) includes a vertical guide rail (532). The side of the tray transporter (550) is coupled to the vertical guide rail (532), thereby guiding the up and down movement of the tray transporter (550).

[0075] A vertical transport unit (540) that moves a tray transporter (550) in a vertical direction is coupled to the side support frame (530). The vertical transport unit (540) includes a belt pulley (544) fixed to the upper and lower portions of the side support frame (530), respectively, and a belt (542) that rotates by the belt pulley (544).

[0076] The belt (542) is connected to the side belt connection portion (551) of the tray transporter (550). As the belt (542) moves, the tray transporter (550) moves vertically while being guided by the vertical guide rail (532). A belt drive motor (545) is connected to the bottom frame (524), and drive shafts (546) extending to both sides of the belt drive motor (545) are connected to the lower belt pulleys (544) of the side support frames (530) on both sides to drive the belt (542).

[0077] The tray transporter (550) is movably connected to the side support frame (530) by a vertical transport member (540).

[0078] The tray transporter (550) includes a support base (560) extending between two side support frames (530), a horizontal guide (570) arranged on the support base (560), and a tray coupler (580) coupled to be movable in the horizontal direction along the horizontal guide (570).

[0079] The support base (560) is formed as a plate, and both bent sides are fixed to the moving block of the vertical guide rail (532). In addition, it is fixed to the belt (542) through the side belt coupling part (551) arranged on the side of the support base (560). Therefore, the support base (560) moves up and down by driving the belt (542). A tray rail (563) is provided on the inner side of the support base (560).

[0080] A horizontal guide (570) is fixed to the upper surface of the support base (560). A tray coupler (580) is movably positioned on the horizontal guide (570).

[0081] The horizontal guide (570) includes horizontal guide rails (574) arranged on both sides of the guide plate (572), and a transfer guide (576), such as an LM guide, arranged between the horizontal guide rails (574).

[0082] The tray coupler (580) is guided by the horizontal guide rail (574) and transported horizontally by the transport force provided by the transport guide (576). A motor (578) that provides the transport force to the transport guide (576) is arranged on the guide plate (572).

[0083] The tray coupler (580) is coupled with the tray (100) and transports the tray (100) horizontally while pulling the tray (100) in the front-back direction. The tray coupler (580) has a horizontal transport distance that can transport the tray (100) past the side portion (400) of the inner tray tower to the side portion of the outer tray tower (300). After the tray coupler (580) transports the tray (100) to the required placement position, the tray coupler (580) is disengaged from the tray (100). After being disengaged from the tray (580), the tray coupler (580) waits at that position or returns to its original position, i.e., to the inside of the tray transport tower (500).

[0084] The tray coupler (580) is coupled to the rear side (105) of the tray (100) (see FIG. 4). The rear side of the tray (100) is the side positioned toward the tray transfer tower (500). The tray coupler (580) includes an attachment portion (582) formed of an electromagnet. For magnetic coupling using the attachment portion (582), at least the rear side of the tray (100) is formed of a magnetic material, such as iron.

[0085] When the tray coupler (580) moves forward and comes into contact with the tray (100), power is applied to the attachment portion (582) formed by the electromagnet to provide magnetic force, and the tray (100) is held by the magnetic force, so that the tray coupler (580) can move the tray (100) in a horizontal direction.

[0086] A contact detection sensor (584) is provided on the front of the tray coupler (580). The contact detection sensor (584) detects the point of contact with the tray (100) and the contact pressure with the tray (100). Through the detection signal of the contact detection sensor (584), the control unit (600) controls the coupling point and the coupling release point between the tray coupler (580) and the tray (100).

[0087] The control unit (600) inputs and outputs relevant information through the operation panel (30), and can provide information on the storage and receipt of cargo to the wireless terminals of the cargo custodian and the cargo recipient by having a wireless interface inside. The wireless terminal can be a smartphone. In addition, the control unit (600) can connect to the courier company's courier system to relay information on the receipt and shipment of courier cargo and the delivery of courier cargo between the courier cargo shipper and the courier cargo recipient, and between the courier cargo sender and the courier cargo transporter.

[0088] In addition, the control unit (600) records the placement of trays (100) in the tray frames (200) forming the side portions of the outer tray tower (300) and the inner tray tower (400), loading information of each tray (100), and controls the movement of the inner tray tower (400) and the tray transfer tower (500).

[0089] The control unit (600) uses a tray transporter (550) to extract trays (100) assigned to trays for loading cargo according to logic from each tray frame (200) of the outer tray tower (300) and the inner tray tower (400), and then inserts the trays into the cargo inlet (340).

[0090] For example, assuming that the assigned tray (100) is in the tray tower (200) of the outer tray tower (300), the control unit (600) rotates the inner tray tower (400) and the tray transfer tower (500) so that the front direction of the tray guide frame (202) of the inner tray tower (400) and the tray transporter (550) of the tray transfer tower (500) are aligned in the direction of the tray tower (200) of the outer tray tower (300) where the assigned tray (100) is located. To this end, the rotation guide (410) and the rotation stage (510) are rotated. At this time, the tray transporter (550) is transferred in the mathematical direction corresponding to the position of the assigned tray (100) in the transfer frame (520).

[0091] With the directions aligned, the tray coupler (580) moves forward and is coupled to the rear side (105) of the tray (100). The tray coupler (580) returns the tray (100) into the tray transfer tower (500) while holding the tray (100).

[0092] Thereafter, the inner tray tower (400) and the tray transfer tower rotate so that the front direction of the cargo inlet (340) of the outer tray tower (300), the tray guide frame (202) of the inner tray tower (400), and the tray transporter (550) of the tray transfer tower (500) are aligned.

[0093] And, in a state where the vertical position of the tray transporter (550) in the tray transfer tower (500) is aligned with the cargo inlet (340), the tray coupler (580) moves forward and places the tray (100) in the cargo inlet (340). After the tray coupler (580) is disengaged from the tray (100), it can return into the tray transfer tower (500) or wait in the disengaged position. At this time, the electromagnet of the attachment part (582) is deactivated.

[0094] When cargo is loaded into the cargo inlet (340), and the control unit (600) determines that the cargo meets the limit height and limit weight, and when the measures for cargo loading, such as inputting information for loading the cargo, are satisfied, the tray coupler (580) moves backward to load the tray (100) loaded with cargo into the tray transfer tower (500).

[0095] Thereafter, the inner tray tower (400) and the tray transfer tower (500) rotate so that the front direction of the tray frame (200), the tray guide frame (202), and the tray transporter (550) on which the tray (100) is to be placed are aligned. The tray transporter (550) is moved vertically to adjust the vertical position, and the tray coupler (580) moves forward to load the tray (100) onto the tray frame (200).

[0096] The control unit (600) selects a tray (100) on which cargo is to be loaded in the lower priority according to logic, and moves and places the tray (100) to the cargo inlet (340) according to the method described above.

[0097] When receiving cargo, the control unit (600) finds a tray (100) loaded with cargo to be received, and transports the tray loaded with cargo to the cargo inlet (340) in the manner described above. This allows the cargo recipient to receive the cargo.

[0098] The cargo storage tower (10) according to the present invention is installed in a shared space such as an apartment complex or a place where people frequently come and go.

[0099] The delivery person, recipient, and sender of the parcel cargo can receive, deliver, send, and store the parcel cargo (P) through the cargo storage tower (10) without the help of separate personnel.

[0100] For example, a courier delivers a parcel to a cargo storage tower (10) and transmits information to the recipient, such as a smartphone, to enable receipt of the parcel via the courier system or the control unit of the cargo storage tower. The recipient can then use the information to receive the parcel from the cargo storage tower (10).

[0101] In the opposite case, the sender of the parcel cargo stores the parcel cargo to be sent in a cargo storage tower (10), and the transporter of the parcel cargo receives the parcel cargo from an unmanned cargo storage tower (10), and then transports the parcel cargo according to the normal parcel cargo transport method.

[0102] The cargo storage tower according to the present invention comprises a height measurement sensor and a load cell. Accordingly, the control unit can calculate a cost based on the size and weight of the parcel when the parcel sender receives the parcel, request payment of the cost through a payment system, and request that the parcel invoice be printed and attached to the parcel (P).

[0103] In addition, the cargo storage tower (10) according to the present invention can be used not only for sending and receiving parcel cargo, but can also be installed in a public place and used for transferring cargo between individuals.

[0104] The above description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that the present invention can be readily modified into other specific forms without altering the technical spirit or essential characteristics of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of the present invention is defined by the following claims, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
