Description

Robot transfer box

[0001] The present invention relates to a robot transfer box, and more specifically, to a robot transfer box capable of easily loading and transferring multiple layers of robots.

[0002] Generally, an autonomous robot refers to a robot that independently surveys its surroundings, detects obstacles, and uses wheels or legs to select the optimal path to reach its destination. Recently, the demand for autonomous robots is gradually increasing due to labor shortages and the growing trend toward non-face-to-face interactions.

[0003] According to conventional technology, autonomous robots are utilized to the extent of automatically delivering food in places such as restaurants or delivering packages unmanned in apartment complexes. In particular, autonomous robots based on conventional technology implement a method in which the robot travels autonomously to a destination, after which the user (consumer) retrieves the delivered item.

[0004] However, conventionally, in order to transport such autonomous robots (hereinafter referred to as robots) to a place of purchase, the robots are moved and loaded through a ramp passage connected to the trunk of a vehicle, and then transported to a place of sale for delivery. This presents a problem in that it is difficult to transport robots in large quantities because there is no method to transport multiple robots by stacking them vertically.

[0005] Therefore, there is a need to improve this.

[0006] A related background technology is Korean Patent Publication No. 2024-0103436 (July 4, 2024, Title of Invention: Autonomous Transport Robot and Delivery Method Using the Same).

[0007] The present invention was created out of the above-mentioned necessity, and aims to provide a robot transport box that allows multiple robots to be easily transported by stacking them vertically using the box body, by placing the box body on the ground, opening the door through the upward movement of the lifting / opening unit to accommodate a robot, and then lifting the box body loaded with the robot to load it onto a vehicle, causing it to descend due to the weight of the door and the lifting / opening unit to block the door of the box body.

[0008] To achieve the above-mentioned purpose, the robot transfer box according to the present invention comprises: a box body having a bottom plate, a plurality of side plates, and a top plate, and a robot receiving a robot through an entrance; a door member that opens and closes the entrance of the box body and rotates by means of a hinge; and a lifting / opening / closing unit that rises when the box body is placed on the ground to open the door member and receive the robot in the box body, and descends by its own weight when the box body is lifted to close the door member and prevent the robot from escaping.

[0009] O-ring bolts are fastened to each corner of the top plate, and hoist wires are connected to each of the O-ring bolts, allowing one box body to be loaded onto another box body.

[0010] A lower space protrusion is formed on the lower plate that protrudes convexly downward, and when the box body is stacked in multiple layers, a space can be formed between the lower space protrusion and the upper space protrusion so that the O-ring bolt formed on the upper plate of the box body located on the lower side does not collide with the lower plate of the box body located on the upper side.

[0011] The above box body may have one or more stopper members installed between the side plates to prevent the robot housed inside from moving out of a predetermined position.

[0012] The above lifting / opening unit may include: a pair of slot holes formed through both corners of the lower plate on the entrance side; a lower frame that is inserted into each of the slot holes and protrudes downward from the lower side of the lower plate and moves up and down when the box body is placed on the ground or lifted; a pair of lifting frames that are each coupled to both sides of the lower frame and move up and down in contact with a plurality of the side plates; and a push rotation unit provided on each of the lifting frames and pushes or releases the hinge part to open or close the door member.

[0013] A gap hole is formed between the upper plate and the door member, so that when the box body is stacked, the lower frame of the box body stacked on the upper side is inserted into the gap hole, thereby preventing the door member of the box body stacked on the upper side from opening.

[0014] When multiple box bodies are stacked, the bottom surface of the box body at the bottom can be supported by a support member to prevent the lower frame of the box body at the bottom from rising.

[0015] The above-mentioned push rotation member may include: a fixed member provided on the lifting frame; a spacing support member bent from the fixed member and spaced apart from the lifting frame at a set interval; and a pressure roller rotatably provided between the lifting frame and the spacing support member to push or release the hinge member to open or close the door member.

[0016] The hinge portion may include: a mounting portion connected to the upper corner of the side plate so as to rotate via a hinge axis; and a rotation guide portion connected to the mounting portion in an L-shape and installed on the door member, which, when the lifting frame is lifted, presses the pressure roller upward or releases the pressure to open or close the door member.

[0017] The above-mentioned rotational guide may have a protruding anti-detachment projection formed thereon to prevent the side of the pressure roller, which moves up and down in contact with the inner surface of the rotational guide, from detachment.

[0018] The above door member may be locked and fixed by the downward movement of the lifting / opening / closing part due to its own weight when the box body is lifted by the locking part, or unlocked by the upward movement of the lifting / opening / closing part when the box body is placed on the ground.

[0019] The locking member may include: a hook shaft member protruding and formed to be hookable on both sides of the lower portion of the door member; a support shaft member fixed to the side of the lifting frame and extending to the outside of the entrance; a pair of hooks rotatably provided on both sides of the end of the support shaft member and rotated by the hook shaft member to hook the hook shaft member; and a weight member integrally connected to the upper side of each hook and which returns the hooks to their original position by their own heavy weight so as to hook the hook shaft member after it has been inserted by the rotation of the hooks.

[0020] The weight member is integrally connected to the upper side of each of the catch hooks, but is further extended to the rear of the support shaft member to increase the distance from the hinge shaft of the catch hook.

[0021] Each of the above side plates is provided with an axle insertion groove into which the hanging shaft member is inserted, thereby restricting the vertical movement of the hanging shaft member.

[0022] The robot transfer box according to the present invention allows a robot to be easily transported by stacking multiple robots side by side in the upper and lower directions using the box body. When the box body with the robot loaded is placed on the ground, the door opens through the upward movement of the lifting / opening unit to accommodate the robot, and when the box body with the robot loaded is lifted and loaded onto a vehicle, it descends due to the weight of the door and the lifting / opening unit to block the door of the box body.

[0023] In addition, the present invention prevents the robot from escaping to the outside through the opening of the door member when the box body is lifted by a hoist wire and loaded onto a vehicle by locking the door member to the box body using a locking part.

[0038] FIG. 7 is an assembled perspective view of a robot transfer box according to an embodiment of the present invention in which a push rotation unit opens a door member through a hinge unit; FIG. 8 is an exploded perspective view of a robot transfer box according to an embodiment of the present invention in which a push rotation unit opens a door member through a hinge unit; FIG. 9 is a drawing showing the state in which a door member is opened when a box body is placed on the ground in a robot transfer box according to an embodiment of the present invention; FIG. 10 is a drawing showing the process of a locking unit engaging as the door member closes by lowering a lifting / opening / closing unit while lifting a box body in a robot transfer box according to an embodiment of the present invention; and FIG. 11 is a cross-sectional view showing the state in which a box body is loaded in a robot transfer box according to an embodiment of the present invention.

[0039] Referring to FIGS. 1 to 11, a robot transfer box according to one embodiment of the present invention includes a box body (100), a door member (200), and a lifting / opening / closing part (300).

[0040] The box body (100) is equipped with a bottom plate (110), a plurality of side plates (120), and a top plate (130), and a robot (10) is accommodated in the entrance (20). The bottom plate (110) and the top plate (130) can be fixed by placing an L-shaped steel member inside the plurality of side plates (120) provided on the left, right, and rear sides, respectively, and bolting them together.

[0041] The robot (10) may be a food transport robot, a parcel delivery robot, or various types of autonomous robots. When delivering the robot (10) to an order location or transporting it for rental, the conventional method of loading it onto a vehicle was not suitable, but by using a cage-shaped box body (100) to accommodate the robot (10) through the entrance (20) and then loading the box body (100) in multiple layers for delivery, the advantage of reducing vehicle space and transportation costs is achieved.

[0042] The door member (200) opens and closes the entrance (20) of the box body (100) and is configured to rotate by means of a hinge part (210).

[0043] The door member (200) can be formed with a size that blocks about 55-70% of the upper side of the box body (100) relative to the area of ​​the side plate (120), taking into account the weight when opened through the lifting / opening / closing unit (300). In this way, if the door member (200) is small, the area that comes into contact with adjacent objects when the door member (200) is opened can be reduced, thereby increasing space utilization.

[0044] The door member (200) is rotatably provided at the upper corner portions on both sides of the side plate (120) of the box body (100) so that a portion of the lower side is opened to the outside.

[0045] Various shapes of perforated holes are formed in the side plate (120) of the box body (100) to reduce weight and allow the condition of the robot (10) housed inside to be identified. In one embodiment of the present invention, the perforated holes are shown as being formed in a hexagon, but as needed, the perforated holes can be configured in various shapes such as circles, squares, pentagons, and geometric patterns.

[0046] Referring to FIG. 1, O-ring bolts (132) are fastened to the top plate (130), and hoist wires (30) are connected to each O-ring bolt (132) so that one box body (100) can be loaded onto another box body (100). Four O-ring bolts (132) are formed at each corner of the top plate (130), so that four hoist wires (30) are gathered at the center and connected as one, allowing the box body (100) containing the robot (10) to be lifted.

[0047] A lower space protrusion (112) is formed on the lower plate (110) and an upper space protrusion (136) is formed on the upper plate (130) that contacts the lower space protrusion (112). When stacking multiple layers of the box body (100), the O-ring bolt (132) formed on the lower upper plate (130) in the space formed through the upper and lower space protrusions (112) (136) can be prevented from hitting the upper lower plate (110) that is stacked.

[0048] The lower space protrusion (112) can be formed by pressing it integrally with a press when forming the lower plate (110), and the upper space protrusion (136) can also be formed by pressing it integrally with a press when forming the upper plate (130).

[0049] When stacking the box body (100) in multiple layers, the upper and lower space protrusions (112) (136) come into contact with each other, forming a receiving space, and the O-ring bolt (132) formed on the lower upper plate (130) is received in this receiving space, so that the O-ring bolt (132) can be safely stacked in multiple boxes (100) in a row in the upper and lower directions without the O-ring bolt (132) hitting the upper lower plate (110).

[0050] The box body (100) may be provided with one or more stopper members (140) that are positioned between the side plates (120) or run across the inside of the side plates (120). The stopper members (140) can connect each of the side plates (120) to prevent the robot (10) housed inside from moving out of a predetermined position.

[0051] The stopper member (140) is formed in the shape of a rod or a plate and is provided as a pair across a position spaced apart by a set distance in the longitudinal direction of the side plate (120) where the door member (200) is opened and closed, thereby preventing the robot (10) loaded through the open door member (200) from hitting the opposite side of the door member (200) through movement. As a result, as shown in FIG. 11, when a user loads and transports the robot (10) into the box body (100), the wheels of the robot (10) are prevented from hitting the box body (100) due to shaking, thereby increasing stability and convenience.

[0052] The lifting / opening / closing unit (300) can rise when the box body (100) is placed on the ground to open the door member (200) and accommodate the robot (10) in the box body (100), and can lower due to its own weight when the box body (100) is lifted to close the door member (200) and prevent the robot (10) from escaping.

[0053] The lifting / opening / closing unit (300) does not automatically open or close the door member (200) using a driving means such as a motor, but rather allows the door member (200) to be opened or closed manually from the box body (100) by placing the box body (100) on the ground or lifting the box body (100) up and down to raise the lifting / opening / closing unit (300).

[0054] The lifting / opening / closing unit (300) may include a pair of slot holes (310) formed through the corners of the lower plate (110) on the entrance / exit side, a lower frame (320) that is inserted into each slot hole (310) and protrudes downward from the lower side of the lower plate (110) and moves up and down when the box body (100) is placed on the ground or lifted, a pair of lifting frames (330) that are connected to each side of the lower frame (320) and move up and down in contact with a plurality of side plates (120), and a push rotation unit (340) provided on each of the lifting frames (330) and pushes or releases the hinge part (210) to open or close the door member (200).

[0055] The slot hole portion (310) is formed as a rectangular hole and is formed slightly larger than the rectangular cross-section of the lifting frame (330) to guide the up and down sliding movement of the lifting frame (330). The slot hole portion (310) is formed as a rectangular hole, but may be formed open toward the door member (200) so as to provide a front-and-back movement space during the lifting of the lower frame (320) and the lifting frame (330).

[0056]

[0057] The lower frame (320) is formed in a U-shape so that a part of it can be inserted into the slot hole (310).

[0058] The lifting frame (330) overlaps with the lower frame (320) and can be joined to the lower frame (320) using rivets or the like.

[0059] A gap hole (134) is formed between the top plate (130) and the door member (200), and the upper lower frame (320) loaded thereon is inserted into the gap hole (134) to prevent the upper door member (200) from opening.

[0060] Referring to FIG. 2 and FIG. 11, the spaced-out hole (134) is a spaced-out space between the ends of the top plate (130) when the door member (200) is closed, and can be formed wider than the width of the lower frame (320).

[0061] As illustrated in FIG. 11, when stacking multiple layers of box bodies (100), a support member (40) having a height greater than or equal to the lowering height when the lower frame (320) is lowered can be provided to prevent the lower frame (320) of the lowest box body (100) from rising, thereby configuring the box body (100) at the lowest side to be horizontally supported.

[0062] The support member (40) may be configured to support the entire bottom surface of the box body (100) adjacent to the lower frame (320) in the form of a pallet, or to support it by being separated into multiple parts with the same height.

[0063] The push rotation part (340) may include a fixed part (350) provided at the end of the lifting frame (330), a spaced support part (360) that is bent at the end of the fixed part (350) and spaced apart from the end of the lifting frame (330) at a set interval, and a pressure roller (370) that is rotatably provided between the lifting frame (330) and the spaced support part (360) to push or release the hinge part (210) to open or close the door member (200).

[0064] Referring to FIGS. 7 to 9, the hinge portion (210) may include a mounting portion (212) that is rotatably connected to the upper corner of the side plate (120) via a hinge shaft (214), and a rotation guide portion (216) that is connected to the mounting portion (212) in an L-shape and installed on the door member (200), and which opens or closes the door member (200) by pressing the pressure roller (370) upward or releasing the pressure when the lifting frame (330) is lifted.

[0065] The mounting part (212) rotates by means of a hinge shaft (214), and the hinge shaft (214) is configured as a ball bearing so that it can absorb some of the up-down-left-right movement when the door member (200) rotates through the mounting part (212) and the rotation guide part (216), thereby guiding the door member (200) smoothly.

[0066] The rotation guide (216) can cause the door member (200) to be gradually rotated and opened when the lifting frame (330) rises through the lower frame (320) by contacting the inner surface of the rounded curved portion of the pressure roller (370).

[0067] The pressure roller (370) provided in the push rotation part (340) can come into contact with the inner end of the rotation guide part (216) when the lifting / opening / closing part (300) descends due to its own weight.

[0068] In addition, when the box body (100) is placed on the ground and the lifting / opening / closing unit (300) rises, the pressure roller (370) is positioned at the inner end of the rotation guide unit (216), so that the gap between the hinge shaft (214) and the pressure roller (370) is formed wide, thereby maintaining a large rotational torque of the door member (200) relative to the side plate (120) of the box body (100), so that the door member (200) can be easily rotated.

[0069] Referring to FIGS. 4, 9 and 10, the door member (200) may be configured to be locked and fixed by the downward movement of the lifting / opening / closing part (300) due to its own weight when the box body (100) is lifted by the locking part (400), or unlocked by the upward movement of the lifting / opening / closing part (300) when the box body (100) is placed on the ground.

[0070] The locking member (400) may include a hanging shaft member (410) formed to protrude so as to be hooked on both sides of the lower portion of the door member (200), a supporting shaft member (420) fixed to the side of the lifting frame (330) and extending to the outside of the entrance (20), a pair of hooks (430) provided to be rotatable by a rotation shaft (432) on both sides of the end of the supporting shaft member (420) and rotated by the hanging shaft member (410) to hook the hanging shaft member (410), and a weight member (440) integrally connected to the upper side of each hook (430) and which returns the hooks (430) to their original position by their heavy weight so as to hook the hanging shaft member (410) after it is inserted by the rotation of the hooks (430).

[0071] The hanging shaft member (410) is installed in a mounting groove (412) formed in a recess at the lower corner of the door member (200), and when hooked onto a hook (430) provided on a lifting frame (330) that contacts the inner side of a plurality of side plates (120), it can block exposure to the outer surface of the side plate (120).

[0072] The upper and lower heights of the mounting groove (412) can be configured to have a height greater than the rising height of the lower frame (320) so that when the lower frame (320) is raised when the box body (100) is placed on the ground, the supporting shaft member (420) and the hook (430) that are provided on the lifting frame (330) and rise together do not get caught on the hooking shaft member (410) provided on the door member (200).

[0073] The support shaft member (420) is formed in a T-shape so that a wide portion of it can be attached to the lifting frame (330) by contacting it vertically and securing it to the lifting frame (330).

[0074] The hook (430) is formed in a triangular shape and the hook shaft member (410) enters through an inclined surface having an angle range of approximately 40 to 50 degrees. After the hook shaft member (410) enters through the rotation of the hook (430) via the rotation axis (432), the hook (430) is restored to a half-rotation and is hooked onto the vertical portion of the hook (430).

[0075] The weight member (440) is configured to be provided in the shape of a square block extending rearward above the rear end of a pair of hooks (430) to add a load to provide a restoring force to the hooks (430) when the hooks (430) return after the hook shaft member (410) has completed its entry.

[0076] The weight member (440) is integrally connected to the upper side of each hook (430), but is formed to extend further to the rear of the support shaft member (420) to increase the distance from the hinge shaft (432) of the hook (430) and thus provide more weight.

[0077] Meanwhile, when the hanging shaft member (410) is engaged and restrained by the hook (430) and the hanging shaft member (410) moves outward due to the opening of the door member (200), the weight member (440) is engaged with the support shaft member (420), thereby stopping the integrally connected hook (430) and blocking the rotation of the hanging shaft member (420) and the opening of the door member (200).

[0078] Each side plate (120) is provided with a shaft insertion groove (414) into which a hanging shaft member (410) is inserted, thereby restricting the up and down movement of the hanging shaft member (410) when the door member is closed.

[0079] The shaft insertion groove (414) can be formed as a semicircular groove or an arc groove so that the upper and lower sides of the hanging shaft member (410), which has a circular cross-section, are caught.

[0080] Below, we examine the process of placing the box body (100) on the ground, accommodating the robot (10), lifting it, and loading it onto a vehicle.

[0081] First, when the box body (100) is placed on the ground, the lower frame (320) is pressed and the lifting frame (330) is raised, and the pressure roller (370) provided at the end pushes the rotation guide part (216) of the hinge part (210) upward, thereby opening the door member (200) based on the hinge shaft (214) provided in the mounting part (212).

[0082] At this time, the support shaft member (420) and the locking hook (430) provided on the lifting frame (330) are raised to release the locking of the hanging shaft member (410), thereby enabling the door member (200) to be opened.

[0083] The robot (10) is accommodated in the box body (100) through the entrance (20) opened by the opening of the door member (200).

[0084] Next, a hoist wire (30) is connected to the O-ring bolts (132) provided at the four corners of the top plate (130), and the top plate is lifted and loaded onto a vehicle.

[0085] At this time, when the robot (10) lifts the box body (100) to deliver the box body (100) to the place of purchase, the lower frame (320) and the lifting frame (330) descend through the slot hole (310) of the bottom plate (110) due to the weight of the lifting opening / closing part (300).

[0086] Then, the rotation guide portion (216) of the hinge portion (210) pressed by the pressure roller (370) returns to its original position, and the door member (200) is closed.

[0087] As shown in FIG. 10, as the support shaft member (420) and the catch hook (430) provided on the lifting frame (330) are lowered, the door member (200) rotates so that the hook shaft member (410) comes into contact with the inclined surface of the catch hook (430), and the catch hook (430) rotates around the rotation axis (432).

[0088] Subsequently, as the self-weight of the locking hook (430) and the load of the weight member (440) are added to return it, the hanging shaft member (410) is locked to the vertical part of the locking hook (430) to prevent the door member (200) from rotating in the opposite direction. The weight member (440) is hooked onto the support shaft member (420) and connected integrally, and also performs the role of a stopper for the locking hook (430) that hooks the hanging shaft member (410).

[0089] In this state, the Bigs main body (100) is lifted by the hoist wire (30) and loaded onto a vehicle, and the box main body (100) is stacked in multiple layers as shown in FIG. 11.

[0090] At this time, the box body (100) located at the bottom is leveled by placing a support member (40) having the height of a lower frame (320) to prevent the opening of the lifting / opening / closing part (300), and the lower frames (320) of the multiple box bodies (100) located at the top are each inserted into the spacing holes (134) provided in the top plate (130) of the box body (100) located at the bottom to prevent being pressed and to stack and deliver in multiple layers.

[0091] Meanwhile, the upper and lower space protrusions (112) (136) formed on the upper plate (130) and lower plate (110) come into contact with each other, and the lower O-ring bolt (132) is received in the receiving space formed, thereby preventing the O-ring bolt (132) from hitting the bottom surface of the upper lower plate (110).

[0092] Accordingly, in a robot transfer box according to one embodiment of the present invention, when the box body is placed on the ground, the door opens through the upward movement of the lifting / opening unit to accommodate a robot, and when the box body loaded with the robot is lifted and loaded onto a vehicle, it descends due to the weight of the door and the lifting / opening unit to block the door of the box body, thereby allowing multiple robots to be easily transferred by stacking them side by side in the upper and lower directions using the box body.

[0093] In addition, the present invention prevents the robot from escaping to the outside through the opening of the door member when the box body is lifted by a hoist wire and loaded onto a vehicle by locking the door member to the box body using a locking part.

[0094] Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0095] Therefore, the true technical scope of protection of the present invention should be determined by the following claims.
