- Referring to
FIG. 1 andFIG. 8 , it is a handlingrobot 100 provided in an embodiment of the present application. The handlingrobot 100 can be applied to an intelligent warehousing system, an intelligent logistics system, an intelligent sorting system, etc. In an embodiment of the present application, the handlingrobot 100 applied to an intelligent warehousing system is taken as an example for detailed illustration. - The handling
robot 100 includes amobile chassis 10, astorage shelf 20, alift component 30, and ahandling device 40. Themobile chassis 10 supports thestorage shelf 20, thelift component 30 and thehandling device 40. - As shown in
FIGS. 1 and 2 , themobile chassis 10 includes ahousing 18. Thehousing 18 has an upper surface which forms arecess 19. Therecess 19 is provided with a bottom surface. - In an embodiment, when the handling
device 40 is lowered to a lowest position, the handlingdevice 40 is, at least in part, within therecess 19. In some implementations, it is not necessary for therecess 19 to support the handlingdevice 40 when the handlingdevice 40 is in a state where the handlingdevice 40 is lowered to the lowest position. - Further referring to
FIGS. 2 and 3 together, themobile chassis 10 includes, but is not limited to, application to the handlingrobot 100. For example, themobile chassis 10 may be applied to an unmanned vehicle, a sweeper, a shuttle, etc. - The
mobile chassis 10 is used to enable the handlingrobot 100 to move on the ground, themobile chassis 10 includes abase plate 11, a drivenwheel component 12, adriving wheel component 13 and a guidingdevice 14. The drivenwheel component 12, thedriving wheel component 13 and the guidingdevice 14 are each mounted to the base. - The base is assembled by welding a steel beam, a steel plate and a skin. The base includes a
base plate 11. Thebase plate 11 is a horizontal rectangular plate member in its entirety and has a horizontal first symmetry axis S1. Thebase plate 11 includes alower surface 1100 and anupper surface 1102 that are back to back, where thelower surface 1100 is toward the ground. - The
base plate 11 is provided with a recessedportion 1104, a first mountingport 1106 and a second mountingport 1108. The recessedportion 1104 is located on thelower surface 1100. The recessedportion 1104 is used for mounting the drivenwheel component 12. The first mountingport 1106 runs through thelower surface 1100 and theupper surface 1102. The first mountingport 1106 is used for allowing thedriving wheel component 13 to pass through. Thesecond mounting port 1108 runs through thelower surface 1100 and theupper surface 1102, and the second mountingport 1108 is used to expose the guidingdevice 14. - The driven
wheel component 12 is a universal wheel. Four drivenwheel components 12 are distributed in a rectangular shape, and the four drivenwheel components 12 jointly support thebase plate 11. It can be appreciated that, according to an actual situation, on the one hand, the drivenwheel component 12 is not limited to a universal wheel, for example, the drivenwheel component 12 may also be a wheel set with a steering bracket (with reference to rear wheel set of a car), as long as the drivenwheel component 12 has a steering function. On the other hand, the number of the drivenwheel component 12 is not limited to four, for example, the number of the drivenwheel component 12 may also be three, five, six, etc., as long as the number of the drivenwheel component 12 is three or more. - Two
driving wheel components 13 are symmetrically distributed relative to the symmetry axis S1, and different rotational speeds between the twodriving wheel components 13 makes the handlingrobot 100 deflect toward a side of one driving wheel component with a lower rotational speed of the twodriving wheel components 13, to realize the steering of the handlingrobot 100. - The driven
wheel component 12 and thedriving wheel component 13 jointly support thebase plate 11. - Further referring to
FIG. 4 , eachdriving wheel component 13 includes adriving wheel 130, ahinge bracket 131 and a shock absorber component. Thedriving wheel 130 is mounted to thehinge bracket 131 and the shock absorber component is mounted to thehinge bracket 131. - The
driving wheel 130 has a horizontal wheel rotation axis O. Thedriving wheel 130 is mounted to thehinge bracket 131. Thedriving wheel 130 is rotatable about the wheel rotation axis O relative to thehinge bracket 131. The wheel rotation axis O is perpendicular to the first symmetry axis S1, and a part of thedriving wheel 130 protrudes from thelower surface 1100 of thebase plate 11 through the first mountingport 1106. - It is worth noting that by providing the recessed
portion 1104 for mounting the drivenwheel component 12, and providing thedriving wheel component 13 on a side that theupper surface 1102 faces and allowing the driving wheel component to protrude from thelower surface 1100 through the first mountingport 1106, it can realize a reduction in both clearance from ground and height of mass center of themobile chassis 10, thereby increasing the ground grip of themobile chassis 10, and improving the stability of movement of themobile chassis 10. - The
driving wheel 130 is driven by a driving wheel motor. Specifically, the driving wheel motor may be a servo motor, and the driving wheel motor drives thedriving wheel 130 to rotate about the wheel rotation axis O relative to thehinge bracket 131. A reducer may also be provided between the driving wheel motor and thedriving wheel 130, a stator of the driving wheel motor is connected to one end of housing of the reducer by a flange, a rotor of the driving wheel motor transmits torque to an input shaft of the reducer by a flat key, the other end of housing of the reducer is connected to thehinge bracket 131 by a flange, an output shaft of the reducer passes through thehinge bracket 131 and transmits torque to thedriving wheel 130 by a flat key. - The
hinge bracket 131 as a whole is a vertical plate member, and thehinge bracket 131 can be a single piece or an assembly assembled by several parts. This is not limited in the embodiment of the present application. - The
hinge bracket 131 is hinged to thebase plate 11 by a bearing seat, and thehinge bracket 131 is rotatable about a first axis L1 relative to thebase plate 11. It can be appreciated that, depending on an actual situation, the bearing seat may be omitted and thehinge bracket 131 is hinged directly to thebase plate 11, a position where thehinge bracket 131 is hinged to thebase plate 11 is located on a side to which theupper surface 1102 is oriented. - In this embodiment, the first axis L1 is parallel to the wheel rotation axis O and the first axis L1 does not coincide with the wheel rotation axis O so that during rotation of the
hinge bracket 131 about the first axis L1 relative to thebase plate 11, a spacing between drivingwheels 130 of twodriving wheel components 13 remains constant and the movement of themobile chassis 10 is stable. - In some other embodiments, the first axis L1 is perpendicular to the wheel rotation axis O.
- One end of the shock absorber component is hinged to the
hinge bracket 131, and the other end of theshock absorber 132 is hinged to theupper surface 1102 of the base plate. - The shock absorber component includes a
shock absorber 132 and an adjustingarm 133 hinged to theshock absorber 132. - The
shock absorber 132 is used to reduce the vibration transmitted to thebase plate 11 via thehinge bracket 131. Theshock absorber 132 realizes the reduction of the vibration at the two ends by compressing lengths of the two ends. One end of theshock absorber 132 is hinged to thehinge bracket 131. Theshock absorber 132 is rotatable about a second axis L2 relative to thehinge bracket 131, and the second axis L2 is parallel to the first axis L1 and the first axis L1 does not coincide with the second axis L2. The other end of theshock absorber 132 is hinged to the adjustingarm 133. Theshock absorber 132 is rotatable about a third axis L3 relative to the adjustingarm 133, and the third axis L3 is parallel to the first axis L1. - One end of the adjusting
arm 133 is hinged to the other end of theshock absorber 132. Theupper surface 1102 of thebase plate 11 is provided with avertical fixing rod 1110, and the other end of the adjustingarm 133 is hinged to the fixingrod 1110. The adjustingarm 133 is rotatable about a fourth axis L4 relative to thebase plate 11, and the fourth axis L4 is parallel to the first axis L1. The adjustingarm 133 abuts against the fixingrod 1110 so that the adjustingarm 133 is not rotatable about the fourth axis L4 relative to thebase plate 11 toward a first direction F1. The first direction F1 is in the same direction as the orientation of theupper surface 1102. - The
shock absorber 132 provides an elastic force to abut the adjustingarm 133 against the fixingrod 1110 and prevent theadjusting arm 133 from rotating toward a second direction F2 relative to thebase plate 11. The second direction F2 is opposite to the first direction F1. The second direction F2 is in the same direction as the orientation of thelower surface 1100. - It can be appreciated that, depending on an actual situation, the fixing
rod 1110 may be omitted, that is, the other end of the adjustingarm 133 is hinged directly to thebase plate 11, and a position where the adjustingarm 133 is hinged to thebase plate 11 is located on a side to which theupper surface 1102 is oriented. The adjustingarm 133 abuts against thebase plate 11, and a position where the adjustingarm 133 abuts against thebase plate 11 is located on a side to which theupper surface 1102 is oriented. - The adjusting
arm 133 is provided with astop portion 1330. Thestop portion 1330 is located on a side of the adjustingarm 133, where the side is orientated towards the first direction F1. - The adjusting
arm 133 and theshock absorber 132 are provided at a first included angle, and the orientation of the opening of the first included angle is in the same direction as the second direction F2. - It is worth noting that, on the one hand, the working environment of the handling
robot 100 is generally a warehouse with a relatively flat floor. On the other hand, thedriving wheel component 13 carries only the weight within the limit of the handlingrobot 100, that is, during the gradual increase of the weight of the handlingrobot 100, thedriving wheel 130 will move towards the side to which the upper surface of thebase plate 11 is oriented, until the lowest point of thedriving wheel 130 is at the same level as the lowest point of the drivenwheel component 12. At this time, weight of the handlingrobot 100 exceeding the limit will be carried by the drivenwheel component 12. Thus, a rotation range of thehinge bracket 131 rotating is limited, and thus a rotation range of theshock absorber 132 rotating is also limited. The first included angle therefore remains substantially unchanged. - When the
shock absorber 132 is assembled, theshock absorber 132 and the adjustingarm 133 are arranged at a second included angle, and the orientation of the opening of the second included angle is in the same direction as the first direction F1. The lengths of two ends of theshock absorber 132 can be elongated so that the elastic force provided by theshock absorber 132 is reduced, which may enable theshock absorber 132 to be mounted conveniently. By first making thestop portion 1330 of the adjustingarm 133 not abut against the fixingrod 1110, and mounting the two ends of theshock absorber 132 to the adjustingarm 133 and thehinge bracket 131 respectively, theshock absorber 132 can be in a natural state or slightly compressed, that is, a connection line between two ends of theshock absorber 132 and a connection line between two ends of the adjustingarm 133 are provided at the second included angle. The orientation of the opening of the second included angle is in the same direction as the first direction F1. Then theshock absorber 132 and the adjustingarm 133 are pulled towards the first direction F1. Theshock absorber 132 is first compressed and then is slightly elongated, so that thestop portion 1330 of the adjustingarm 133 abuts against the fixingrod 1110. By setting the adjustingarm 133, it is not necessary to mount theshock absorber 132 while compressing theshock absorber 132, and the mounting of theshock absorber 132 is more convenient. - In addition, by setting the adjusting
arm 133, after theshock absorber 132 is mounted, the spring tightness of theshock absorber 132 is also easy to be adjusted to adapt to the working environment of the mobile chassis. Specifically, making theshock absorber 132 and the adjustingarm 133 provided at the second included angle, and at this time two ends of theshock absorber 132 are basically not under pressure, and the spring tightness of theshock absorber 132 is easy to adjust. - When the driving wheel motor stops working, the
driving wheel 130 is not rotatable. Therefore, in the case where theshock absorber 132 and the adjustingarm 133 are provided at the first included angle, thedriving wheel 130 supports the chassis. When the handlingrobot 100 is pushed by the drivenwheel component 12 to a maintenance area, thedriving wheel 130 will rub against the ground, therefore preventing the handlingrobot 100 from moving. When theshock absorber 132 and the adjustingarm 133 are provided at the second included angle, since two ends of theshock absorber 132 are basically not under pressure, thedriving wheel 130 basically does not abut against the ground, that is, thedriving wheel 130 does not support the base, and the handlingrobot 100 can be relatively easily pushed to the maintenance area for maintenance. - It can be appreciated that, depending on the actual situation, the adjusting
arm 133 may be omitted, that is, one end of theshock absorber 132 is hinged to thehinge bracket 131 and the other end of theshock absorber 132 is hinged to thebase 11, as long as thedriving wheel 130, thehinge bracket 131, theshock absorber 132 and thebase plate 11 are connected in sequence and two ends of theshock absorber 132 are telescopic. - In comparison with the prior art, in a handling
robot 100 of the embodiment of the present application and itsmobile chassis 10, by setting a shock absorber component in themobile chassis 10, the movement of themobile chassis 10 is more stable. - The guiding
device 14 is mounted to theupper surface 1102 of thebase plate 11. In an embodiment, the guidingdevice 14 is a camera, and lens of the camera is aligned with the second mountingport 1108. The guidingdevice 14 is used to identify the two-dimensional code affixed to the ground, so that the handlingrobot 100 travels along a preset path. - It can be appreciated that, depending on the actual situation, the guiding
device 14 is not limited to a camera. For example, the guidingdevice 14 may also be a laser guiding device for guiding the handlingrobot 100 to travel along a laser beam, or, for another example, the guidingdevice 14 is a short-wave receiving device for achieving a guidance function by receiving a preset short-wave signal, etc. - Referring back to
FIG. 1 , thestorage shelf 20 is mounted to theupper surface 1102 of thebase plate 11. - The
storage shelf 20 includes a plurality of layeredplate components 21 distributed at different heights and avertical beam 22 for supporting eachlayered plate component 21. - Each
layered plate component 21 includes alayered plate 210, a restriction structure and across beam 214. As shown inFIG. 1 , thecross beam 214 is connected (e.g., mounted) to thevertical beam 22. Specifically, one end of thecross beam 214 is mounted to one of twovertical beams 22, and another end of thecross beam 214 is mounted to another of the twovertical beams 22. In an embodiment, thecross beam 214 is connected (e.g., mounted) to thevertical beam 22 by fasteners, such as threaded nuts. In some other embodiments, thecross beam 214 is integrally formed with thevertical beam 22. - The
layered plate 210 is used for placing a material, thelayered plate 210 has two ends distributed horizontally, one end of thelayered plate 210 is close to thevertical beam 22 and the other end of thelayered plate 210 is suspended in the air and away from thevertical beam 22. As shown inFIG. 1 , at least two of the plurality of layeredplate components 21 are wholly supported by the twovertical beams 22. It is obvious fromFIGS. 1, 5 and 7 that thelayered plates 210 of the at least two layered plate components are wholly supported by the twovertical beams 22. For example, as shown inFIG. 1 , with respect to each of the at least two layered plate components, across beam 214 of a particularlayered plate component 21 is mounted to the twovertical beams 22, and alayered plate 210 of the particularlayered plate component 21 is supported by thecross beam 214 of the particularlayered plate component 21. As the weight of thelayered plate 210 of the particularlayered plate component 21 is wholly supported by thecross beam 214 of the particularlayered plate component 21, it is in fact that thelayered plate 210 of the particularlayered plate component 21 is wholly supported by thecross beam 214 of the particularlayered plate component 21. It can be seen fromFIGS. 1 and 5 that thelayered plate 210 is disposed on thecross beam 214. - It is not limited to the shape of the
layered plate 210. In an embodiment, thelayered plate 210 is provided with a flat surface, as shown inFIG. 5 . For example, as shown inFIG. 5 , thelayered plate 210 includes a board with a flat upper surface. This board can be made of wood or various type of metals. The material (inventory item) is placed on the board. In some other embodiments, thelayered plate 210 is provided with a hollowed structure. For example, thelayered plate 210 includes two bars spaced apart with each other, and the two bars are configured to jointly place or support a material (e.g., an inventory item). - In an embodiment, as shown in
FIG. 1 , each of the plurality of layeredplate components 21 is wholly supported by the twovertical beams 22. For example, the layered plate 210 (such as the above board) of each of the plurality of layered plate components is wholly supported by thevertical beam 22 through thecross beam 214 of the each of plurality of layered plate components. - The restriction structure is used to block the material located on the layered plate.
- In this embodiment, the restriction structure is a
surrounding plate 212, the surroundingplate 212 extends at an edge of the layeredplate 21 in a direction away from themobile chassis 10. The surroundingplate 212 is used to block the material placed on thelayered plate 210 to prevent the material placed on thelayered plate 210 from slipping off thelayered plate 210. - It can be appreciated that the restriction structure is not limited to the surrounding
plate 212. Depending on the actual situation, the restriction structure may also be a columnar structure provided close to the edge of the layered plate. - Referring to
FIGS. 5 and 6 , eachlayered plate component 21 includes a plurality of surroundingplates 212. The edge of thelayered plate 210 has a plurality of side edges, each surroundingplate 212 extends on one side edge of the layered plate 210 Ajoint structure 216 is provided at a gap between each two adjacent surroundingplates 212. Thejoint structure 216 is jointed with two adjacent surroundingplates 212 respectively such that an arc-shaped corner is formed at a corner of the two adjacent surroundingplates 212. - The
joint structure 216 has twoslots 2160. Side edges of two adjacent surroundingplates 212 are embedded in the twoslots 2160, respectively. Thejoint structure 216 is fixed to thelayered plate 210 by a screw. - Each surrounding
plate 212 includes a surrounding platemain body 2120 and aflanging body 2122. Theflanging body 2122 extends at an edge of the surrounding platemain body 2120 facing away from thelayered plate 210, and theflanging body 2122 fits to the surrounding platemain body 2120 so that a position where theflanging body 2122 is connected to the surrounding platemain body 2120 is shaped into an arc transition. - The
flanging body 2122 and thelayered plate 210 are located on the same side of the surrounding platemain body 2120. - Further referring to
FIG. 7 , a side of thelayered plate 210 facing away from themobile chassis 10 is used for placing a material. Thecross beam 214 is located on a side of thelayered plate 210 facing themobile chassis 10, and thecross beam 214 is close to one end of thelayered plate 210. As shown inFIGS. 1, 5 and 7 , thecross beam 214 is located beneath thelayered plate 210 and configured to support weight of thelayered plate 210, as well as weight of an inventory item if the inventory item is placed on thelayered plate 210. - In an embodiment, the
cross beam 214 is connected to a side of thelayered plate 210 facing themobile chassis 10 by asupport plate 218 located beneath thelayered plate 210. For example, as shown inFIG. 7 , thesupport plate 218 is mounted to a lower side of thelayered plate 210. In an embodiment, thesupport plate 218 is installed to thelayered plate 210 by screws. In another embodiment, thesupport plate 218 and the lower side of thelayered plate 210 are integrally formed into one piece, as shown inFIG. 7 . - In an embodiment, the
support plate 218 is mounted to thecross beam 214 by screws, as shown inFIG. 7 . In some other embodiments, thesupport plate 218 is integrally formed with thecross beam 214. It should be noted that both thesupport plate 218 and thelayered plate 210 may be integrally formed with thecross beam 214. - It is not limited to the number of the
support plates 218. For example, there may be more than twosupport plates 218 disposed vertically and parallelly to each other. In an embodiment, there may be twosupport plates 218, as shown inFIG. 7 , where each of the twosupport plates 218 is disposed vertically and is parallel to another. In another embodiment, three ormore support plates 218 are provided. In some other embodiment, there may be asingle support plate 218. - Two
vertical beams 22 are symmetrically distributed relative to the symmetry axis S1. - Referring to
FIG. 8 , thevertical beam 22 is detachably connected, specifically by a bolt, to theupper surface 1102 of thebase plate 11. - The
vertical beam 22 is provided with a mountingslot 220 and avertical guideway 222. - The mounting
slot 220 is used for mounting thelift component 30, and the mountingslot 220 is located within thevertical beam 22. - The
vertical guideway 222 is used for mounting the handlingdevice 40, and thevertical guideway 222 is provided on a surface of thevertical beam 22. Thevertical guideway 222 is connected with the mountingslot 220, and thevertical guideway 222 and the mountingslot 220 form a closed loop. - The
vertical beam 22 is provided with acushion 224 at the end of thevertical guideway 222. Thecushion 224 can be made of such material as sponge or rubber, etc. Thecushion 224 can prevent thehandling device 40 from directly colliding with thevertical beam 22 when rising to the highest point or falling to the lowest point. - The
cushion 224 protrudes into thevertical guideway 222 and abuts against thelift component 30. - The
lift component 30 is used to drive the handlingdevice 40 to lift (e.g., raise or lower) relative to thestorage shelf 20. - The
lift component 30 includes a synchronousbelt pulley mechanism 31 and a lift driving motor. The lift driving motor is used to drive the handlingdevice 40 to raise or lower relative to thestorage shelf 20 by the synchronousbelt pulley mechanism 31. - The synchronous
belt pulley mechanism 31 is mounted in the mountingslot 220. Thesynchronous belt 310 of the synchronousbelt pulley mechanism 31 is located in the closed loop, and thesynchronous belt 310 of the synchronousbelt pulley mechanism 31 is connected to thehandling device 40. - The lift driving motor drives an
active belt pulley 311 of the synchronousbelt pulley mechanism 31 to rotate through a lift driving reducer, a gear set and a transmission shaft. Depending on the actual situation, one or more of the lift driving reducer, the gear set and the transmission shaft can be omitted. - The
synchronous belt 310 of the synchronousbelt pulley mechanism 31 abuts against thecushion 224 so that dust does not easily enter from thevertical guideway 222 into the mountingslot 220, avoiding a power drop caused by the accumulation of dust in the synchronousbelt pulley mechanism 31. - Referring to
FIGS. 9 and 10 , thelift component 30 further includes abraking device 32; thebraking device 32 is used to stop the synchronousbelt pulley mechanism 31 from working. - The
braking device 32 includes abraking disc 320, a guidingbase 322, apin 324, aresilient member 326 and acam 328. Thebraking disc 320 is provided coaxially with theactive belt pulley 311 of the synchronousbelt pulley mechanism 31. Thebraking disc 320 rotates synchronously with theactive belt pulley 311 of the synchronousbelt pulley mechanism 31 when the synchronousbelt pulley mechanism 31 is in operation. Thebraking disc 320 is provided with one ormore pin holes 3200, and the pin holes 3200 rotates synchronously with thebraking disc 320 when thebraking disc 320 rotates. - The guiding
base 322 is mounted to thevertical beam 22 and the guidingbase 322 is provided with asocket 3220. - The
pin 324 is inserted into thesocket 3220. As thebraking disc 320 rotates, one end of thepin 324 can be aligned with and inserted into thepin hole 3200 to stop thebraking disc 320 and the synchronousbelt pulley mechanism 31 provided coaxially with thebraking disc 320 from working. - The
cam 328 is located on a side of the guidingbase 322 away from thebraking disc 320. Thecam 328 is rotatably connected to the other end of thepin 324, and thecam 328 is rotatable about its wheel center relative to thepin 324. A wheel face of thecam 328 abuts against the side of the guidingbase 322 away from thebraking disc 320 so that thepin 324 moves along thesocket 3220 relative to the guidingbase 322. - The
resilient member 326 is used to enable thecam 328 to abut against the guidingbase 322 and provide a pressing force to keep thepin 324 stationary. Specifically, theresilient member 326 is a compression spring. A first retaining ring 3240 is protrudingly provided on a middle portion between two ends of thepin 324, and asecond retaining ring 3222 is protrudingly provided on a wall of thesocket 3220. Thesecond retaining ring 3222 is located between the first retaining ring 3240 and thecam 328. Theresilient member 326 is sheathed on thepin 324, and theresilient member 324 abuts between the first retaining ring 3240 and thesecond retaining ring 3222. - A
spanner 329 is provided on thecam 328. An operator pulls thespanner 329 to drive thecam 328 to rotate, so that the synchronousbelt pulley mechanism 31 stops working. It can be appreciated that, depending on the actual situation, a cam driving motor may also be provided to drive thecam 328 to rotate so as to achieve braking of the synchronousbelt pulley mechanism 31. - It should be noted that implementation of the lifting transmission mechanism is not limited to the synchronous belt pulley mechanism. For example, the lifting transmission mechanism may also be any one of a sprocket wheel mechanism, a gear rack mechanism, a turbine worm mechanism, and a lifting screw mechanism, as long as the lifting transmission mechanism, at least in part, is mounted in the mounting
slot 220. - It should be noted that there are many ways to mount the lifting transmission mechanism in the mounting
slot 220. In an embodiment, a part of the lifting transmission mechanism is mounted in the mountingslot 220. In another embodiment, the whole of the lifting transmission mechanism is mounted in the mountingslot 220. - For example, in an embodiment, the synchronous
belt pulley mechanism 31 including two belt pulleys is wholly housed in the mountingslot 220. However, in some other embodiments, only a part of the synchronous belt pulley mechanism 31 (e.g., the top belt pulley) is within the mountingslot 220. - Referring to
FIG. 11 , the handlingdevice 40 includes a handlingassembly bracket 41, a handlingassembly 42 and arotation driving device 43. The handlingassembly 42 is mounted to thehandling assembly bracket 41, and therotation driving device 43 is mounted between the handlingassembly 42 and the handlingassembly bracket 41. - It can be seen from
FIG. 1 that the handlingdevice 40 andlayered plates 210 of the plurality of layeredplate components 21 are disposed at two different sides of the twovertical beams 22. For example, as shown inFIG. 1 , the twovertical beams 22 form a vertical plane. The handlingdevice 40 is located at a right side of the vertical plane and is disposed at the right side of the twovertical beams 22. Thelayered plates 210 are located at a left side of the vertical plane and are disposed at the left side of the twovertical beams 22. It should be noted that as long as an end of a particularlayered plate 210 suspended in the air and away from the twovertical beams 22 is located at the left side of the twovertical beams 22, this particularlayered plate 210 for placing a material is located or disposed at the left side of the twovertical beams 22, and vice versa. As long as the handlingassembly bracket 41 or therotation driving device 43 is located at the right side of the twovertical beams 22, the handlingdevice 40 is disposed at the right side of the twovertical beams 22, and vice versa. - The handling
assembly bracket 41 is assembled by welding a steel beam and a steel plate. The handlingassembly bracket 41 is provided with a slidingmember 410. Two slidingmembers 410 are symmetrically distributed relative to the first symmetry axis S1, and the two slidingmembers 410 are each mounted to a correspondingvertical guideway 322. The slidingmember 410 can move along thevertical guideway 322 to enable thehandling device 40 to lift relative to thestorage shelf 20. - The handling
assembly bracket 41 is connected to the handlingassembly 42 by a cross roller bearing or a cross ball bearing so that the handlingassembly 42 is rotatable about a vertical direction relative to thehandling assembly bracket 41. Depending on the actual situation, the handlingassembly bracket 41 and the handlingassembly 42 are not limited to being connected by a cross roller bearing, for example, the handlingassembly bracket 41 and the handlingassembly 42 may also be connected by a slewing bearing. - The
rotation driving device 43 includes a rotation driving motor, a fixedpulley 430, a handling assemblysynchronous belt pulley 432 and a handling assemblysynchronous belt 434. A side of the handlingassembly bracket 41 towards the handlingassembly 42 is fixedly mounted with the fixedpulley 430, and the fixedpulley 430 is coaxially provided with the cross roller bearing. The handling assemblysynchronous belt pulley 432 is rotatably mounted to the handlingassembly 42 about a vertical direction. The handling assemblysynchronous belt 434 is connected to the handling assemblysynchronous belt pulley 432 and the fixedpulley 430. The rotation driving motor is used to drive the handling assemblysynchronous belt pulley 432 to rotate relative to the handlingassembly 42 so that the handlingassembly 42 rotates about the vertical direction relative to thehandling assembly bracket 41. - In an embodiment, the fixed
pulley 430 is provided with a synchronousbelt press block 4300 convex on its outer wheel face. The synchronousbelt press block 4300 abuts against the handling assemblysynchronous belt 434 so that the handling assemblysynchronous belt 434 is tensioned. - In some embodiments, the fixed
pulley 430 and thesynchronous belt pulley 432 may be a sprocket wheel, and thebelt 434 is a roller chain. - The handling
assembly 42 is provided with afirst locking hole 4200 and the handlingassembly bracket 41 is provided with asecond locking hole 4100. A lockingpin 44 can be inserted into thefirst locking hole 4200 and thesecond locking hole 4100 simultaneously, so that the handlingassembly 42 is not rotatable about a vertical direction relative to thehandling assembly bracket 41. - A side of the handling
assembly bracket 41 towards the handlingassembly 42 is mounted with afirst restriction block 450, and a side of the handlingassembly 42 towards the handlingassembly bracket 41 is mounted with asecond restriction block 452. Thefirst restriction block 450 is used to abut against thesecond restriction block 452 to enable the handlingassembly 42 to rotate within a preset angle range. - The handling
device 40 further includes afirst angle sensor 460, asecond angle sensor 461 and a controller. Thefirst angle sensor 460 and thesecond angle sensor 461 are both connected to the controller. - The
first angle sensor 460 is used to detect whether the handlingassembly 42 rotates to be within a first preset angle range relative to thehandling assembly bracket 41, and thesecond angle sensor 461 is used to detect whether the handlingassembly 42 rotates to be within a second preset angle range relative to thehandling assembly bracket 41. It is noted that the first preset angle range and the second preset angle range are both included in the preset angle range, and there is an intersection between the first preset angle range and the second preset angle range. The intersection between the first preset angle range and the second preset angle range is a reference angle, and the reference angle is either a specific value or a continuous range of values. - The
first angle sensor 460 and thesecond angle sensor 461 are both proximity switches. The handlingdevice 40 further includes adetection plate 462. Both thefirst angle sensor 461 and thesecond angle sensor 462 are mounted to a side of the handlingassembly bracket 41 towards the handlingassembly 42. Thedetection plate 462 is mounted to a side of the handlingassembly 42 towards the handlingassembly bracket 41. When the first angle sensor rotates with the handlingassembly 42 to be directly opposite to thedetection plate 462, thefirst angle sensor 460 detects that the handlingassembly 42 rotates to be within the first preset angle range. When thefirst angle sensor 460 rotates with the handlingassembly 42 to be not directly opposite to thedetection plate 462, thefirst angle sensor 460 detects that the handlingassembly 42 does not rotate to be within the first preset angle range. Similarly, when thesecond angle sensor 461 rotates with the handlingassembly 42 to be directly opposite to thedetection plate 462, thesecond angle sensor 461 detects that the handlingassembly 42 rotates to be within the second preset angle range. When thesecond angle sensor 461 rotates with the handlingassembly 42 to be not directly opposite to thedetection plate 462, thesecond angle sensor 461 detects that the handling assembly does not rotate to be within the second preset angle range. When both thefirst angle sensor 460 and thesecond angle sensor 461 are directly opposite to thedetection plate 462, the handlingassembly 42 rotates to be within the intersection of the first preset angle range and the second preset angle range, that is, the handlingassembly 42 rotates to the reference angle. - The controller is connected to the rotation driving motor. When the
first angle sensor 460 detects that the handlingassembly 42 rotates to be within the first preset angle range and thesecond angle sensor 461 detects that the handlingassembly 42 does not rotate to be within the second preset angle range, the controller controls the rotation driving motor to operate so that the handlingassembly 42 rotates to be within the second preset angle range. When thefirst angle sensor 460 detects that the handlingassembly 42 does not rotate to be within the first preset angle range and thesecond angle sensor 461 detects that the handlingassembly 42 rotates to be within the second preset angle range, the controller controls the rotation driving motor to operate so that the handlingassembly 42 rotates to be within the first preset angle range. When thefirst angle sensor 460 detects the handlingassembly 42 rotates to be within the first preset angle range and thesecond angle sensor 461 detects the handlingassembly 42 rotates to be within the second preset angle range, the controller controls the rotation driving motor to stop operating, and at this time the handlingassembly 42 is at the reference angle. - The handling
assembly 42 is used to transport a material to alayered plate 210 at the same height as the handlingassembly 42, or to transport a material out of alayered plate 210 at the same height as the handlingassembly 42. The handlingassembly 42 may be at the same height as alayered plate 210 when the handlingdevice 40 lifts relative to the storage shelf. - The handling
assembly 42 has a horizontal second symmetry axis S2. The handlingassembly 42 includes atemporary storage pallet 420, atelescopic arm 421, a fixedpusher 422 and amovable pusher 423. Where one end of thetelescopic arm 421 is mounted to thetemporary storage pallet 420, and both the fixedpusher 422 and themovable pusher 423 are mounted at the other end of thetelescopic arm 421. The fixedpusher 422 is closer to one end of thetelescopic arm 421 than themovable pusher 423, where the one end of thetelescopic arm 421 is mounted to thetemporary storage pallet 420. The other end of thetelescopic arm 421 may extend or retract along the second symmetry axis S2 relative to thetemporary storage pallet 420, and drive the fixedpusher 422 and themovable pusher 423 to extend or retract. Themovable pusher 423 may be expanded or folded relative to thetelescopic arm 421. - Two
telescopic arms 421 are symmetrically provided on two opposite sides of the second symmetry axis S2, and each of twotelescopic arms 421 is mounted with onemovable pusher 423. The fixedpusher 422 is connected between the twotelescopic arms 421. Depending on the actual situation, the number of thetelescopic arms 421 is not limited to two, and the number of thetelescopic arm 421 may also be one. - Further referring to
FIG. 12 , eachtelescopic arm 421 includes anouter section arm 424, amiddle section arm 425 mounted to theouter section arm 424, and aninner section arm 426 mounted to themiddle section arm 425.

FIGS. 1 and 12 , the handlingassembly 42 includes aU-shaped housing 4210. TheU-shaped housing 4210 is installed around thetemporary storage pallet 420 and configured to prevent the material (e.g., inventory item) on thetemporary storage pallet 420 from falling off. Because of theU-shaped housing 4210, thetelescopic arm 421 is only extendable in a single direction. - At least a part of the
temporary storage pallet 420 and thetelescopic arm 421 is in theU-shaped housing 4210. For example, as shown inFIG. 12 , at least a part of the telescopic arm 421and at least a part of thetemporary storage pallet 420 are housed in theU-shaped housing 4210. - As shown in
FIG. 12 , theU-shaped housing 4210 includes aleft housing member 4211, aright housing member 4212, and arear housing member 4213.

U-shaped housing 4210. In an embodiment, theleft housing member 4211, theright housing member 4212 and therear housing member 4213 are integrally formed into one piece. In some other embodiments, theleft housing member 4211, theright housing member 4212 and therear housing member 4213 are separate components. Both theleft housing member 4211 and theright housing member 4212 may be connected to therear housing member 4213 via fasteners, such as screwed nuts. However, it may be also possible that one of theleft housing member 4211 and theright housing member 4212 is integrally formed with therear housing member 4213, and another of theleft housing member 4211 and theright housing member 4212 is connected to therear housing member 4213 by fasteners. - In an embodiment, the
left housing member 4211 may be integrally formed with one of twotelescopic arms 421, and theright housing member 4212 may be integrally formed with another of the twotelescopic arm 421. - It is not limited to the shape and structure of each of
