Referring to fig. 2 and 3, a first embodiment of the present application provides an automatic loading and unloading apparatus 001 for transferring cargo 006 between a loading position and a unloading position having a height difference at a quay 003 or the like. The automatic loading and unloading apparatus 001 includes a lifting plate 100 having a loading surface 101 for loading the goods 006, and a driving means for transferring the goods 006 on the loading surface 101 to be displaced between a discharging position and a loading position having a height difference, the driving means including a lifting part 200 and a traverse part 300; the lifting part 200 comprises an outer frame 210 and a lifting driving device 230, the lifting plate 100 is accommodated in the outer frame 210, the driving end of the lifting driving device 230 drives the lifting plate 100 to lift in the outer frame 210, and the outer frame 210 is provided with a first opening 211 facing the wharf 003 and a second opening 213 facing away from the wharf 003; the traverse section 300 is provided on the bearing surface 101 for driving the goods 006 into or out of the bearing surface 101.

With this automatic loading and unloading apparatus 001, the cargo 006 at a high position on the quay 003 is carried to one side of the lifting plate 100, the cargo 006 on the quay 003 is horizontally moved onto the lifting plate 100 by the horizontal moving portion 300, the lifting plate 100 is lowered to the height, and when the lifting plate 100 is lowered to abut against the car under the quay 003, the horizontal moving portion 300 horizontally moves the cargo 006 on the lifting plate 100 out of the lifting plate 100, and the cargo 006 enters the car under the quay 003. Conversely, the cargo 006 at a lower position on the dock 003 can be transported to one side of the lifting plate 100 through the carriage, the cargo 006 on the carriage can be transversely moved onto the lifting plate 100 through the transverse moving part 300, the lifting plate 100 is lifted, when the lifting plate 100 is lifted to be in butt joint with the transport vehicle on the dock 003, the transverse moving part 300 transversely moves the cargo 006 on the lifting plate 100 out of the lifting plate 100, and the cargo 006 enters the transport vehicle on the dock 003. When the automatic loading and unloading equipment 001 is butted with the manned truck 005, the manned truck 005 is provided with the tail plate corresponding to the wharf 003, at the moment, the lifting plate 100 does not need to be lifted, and the goods 006 on the wharf 003 can be transversely moved to the carriage of the manned truck 005 through the lifting plate 100 with the height equal to the height of the wharf 003 in the butt joint of the boarding 005 and the boarding guard of the manned truck, namely the transverse moving part 300 on the lifting plate 100.

Referring to fig. 3 and 4, in order to increase the stability of the lifting plate 100 during the lifting process, the lifting plate 100 is configured as a bottom plate of the lifting box 010, one side of the lifting box 010 facing the first opening 211 is provided with a third opening, and one side facing the second opening 213 is provided with a fourth opening, so that the cargo 006 can be conveniently moved in and out through the third opening and the fourth opening.

The side wall of the lift box 010 forms a larger contact area with the outer frame 210, thereby increasing the stability of the lift plate 100, so that the outer frame 210 can keep the lift box 010 to keep the lift plate 100 in a horizontal state all the time, and the lift plate 100 is prevented from inclining when bearing heavier goods 006. In addition, the traverse portion 300 is required to be installed on the lifting plate 100, and the side plate of the lifting box 010 can be used as an installation base to facilitate installation of various parts.

Referring to fig. 5, in order to prevent the goods 006 from falling down during the lifting process of the lifting plate 100 and sliding out of the lifting plate 100, in some embodiments, the third opening and the fourth opening are provided with safety doors 011. In other embodiments, a safety door 011 can be provided only at the third opening or the fourth opening to ensure that the tilted cargo 006 can be supported and resisted in one direction.

In order to control the lifting of the lifting plate 100, the lifting driving device 230 includes a first power unit 231 and a first control unit 233, the first power unit 231 provides power for the lifting of the lifting plate 100, and the first control unit 233 is electrically connected to the first power unit 231 to control the power output of the first power unit 231.

The first power unit 231 may be in the form of a motor-driven gear rack, a motor-driven chain transmission, a motor-driven wire rope traction, and the like, and these are commonly used technical means in the field of driving the goods 006 to ascend and descend, and will not be described herein again. Since the lifting plate 100 needs to be docked at various height positions, the lifting height position should be non-jumping, and the lifting plate 100 can be fixed at any position within the whole lifting interval of the lifting plate 100. In order to control the position of the lifting plate 100, a first control unit 233 is provided, and the first control unit 233 may be manually operated or may be interfaced with a sensor, and the lifting and fixing of the lifting plate 100 may be automatically controlled by data information obtained from the sensor.

In order to accurately grasp the height of the lifting plate 100, the first control unit 233 further includes a height sensor 2331, and the height sensor 2331 is disposed in the outer frame 210 for monitoring the height of the lifting plate 100 in the outer frame 210. The height sensor 2331 may be a grating ruler or a hall sensor, and the height sensor 2331 is installed in the outer frame 210 to monitor the height of the lifting plate 100.

The auto-control handling equipment 001 further needs to be docked with an external transportation device 002, so the lifting driving device 230 further comprises a wireless communication unit 235, the wireless communication unit 235 is in wireless communication with the transportation device 002 and is electrically connected with the first control unit 233 to provide the state of the transportation device 002 to the first control unit 233, and the first control unit 233 is convenient for controlling the power output of the first power unit 231.

The traverse section 300 includes a plurality of conveying rollers 330 arranged in parallel for smooth transportation of the goods 006, and the conveying rollers 330 are rotatably coupled to the lifting plate 100. The goods 006 frictionally acts with the transfer roller 330 to be displaced in a direction perpendicular to the transfer roller 330 following the rotation of the transfer roller 330. And the transfer roller 330 has a high strength, is not easily damaged although directly contacting the goods 006 and bearing the weight of the goods 006, has a long service life, and can improve the overall life of the auto-handler 001.

In order to control the traverse of the traverse portion 300, the traverse portion 300 further includes a second power unit having an output end coupled to the conveying roller 330 to drive the conveying roller 330 to rotate, and a second control unit electrically connected to the second power unit to control the power output of the second power unit.

The second power unit may be a motor driven chain, with sprockets at the ends of all of the transfer rollers 330, with the chain sprockets being driven by gears as well. The transmission mode of the transmission roller 330 is a common technical means, and is not described in detail herein. Because the position of the goods 006 needs to be controlled when the removal of goods 006 on sideslip portion 300 needs to be realized on the goods 006 entering lifter plate 100, avoid goods 006 not all to get into lifter plate 100 and result in the lifter plate 100 to descend the time goods 006 are scraped, also need to avoid goods 006 sideslip excessively to lead to goods 006 to transport out and fall from the opposite side of lifter plate 100. The second control unit is thus arranged to control the power output of the second power unit.

In order to control the second power unit more precisely through the second control unit, the second control unit includes a sensor group 350, and the sensor group 350 is fixedly connected to the lifting plate 100 for sensing whether the load bearing surface 101 has the cargo 006. The state of the cargo 006 on the lift plate 100 is judged by the sensor group 350.

Specifically, the sensor group 350 includes a first sensor 351 near the first opening 211, and a second sensor 355 near the second opening 213. The sensor group 350 further includes a presence sensor 353 located between the first sensor 351 and the second sensor 355, the presence sensor 353 having a sensing range covering 30% -70% of the area of the bearing surface 101.

The first sensor 351, the second sensor 355, and the presence sensor 353 are all provided on a side wall of the lift box 010. Whether the goods 006 enter the lift plate 100 can be determined by the first sensor 351, and whether the goods 006 are carried out of the lift plate 100 can be determined by the second sensor 355. The presence of the cargo 006 on the lifting plate 100 can be determined by the presence sensor 353. In order to accurately sense the entrance and exit of the cargo 006 as much as possible, the first sensor 351 is disposed as close to the third opening of the lift box 010 as possible, and the second sensor 355 is disposed as close to the fourth opening of the lift box 010 as possible. To avoid missing detection of the cargo 006 at a low height, the first sensor 351, the second sensor 355 and the presence sensor 353 are located as close as possible to the load surface 101.

In other embodiments, when the lifting board 100 is not formed by the lifting box 010, a side plate needs to be disposed at a side of the lifting board 100, and the side plate needs to extend to above the traverse portion 300.

Since the traverse section 300 employs the conveying roller 330 to traverse the cargo 006, the conveying roller 330 is slightly insufficient in stabilizing the cargo 006, and a clamping device 400 is further provided on the bearing surface 101 in order to stabilize the cargo 006 during the lifting and lowering of the lifting and lowering section 200.

Referring to fig. 4 and 7, an installation space is formed between the conveying rollers 330 and the carrying surface 101, and a gap is formed between two adjacent conveying rollers 330; the clamping device 400 includes two opposing sets of clamping members 410. Referring to fig. 8, each group of clamping members 410 includes a rotating shaft 411 and a plurality of clamping jaws 413, the clamping jaws 413 are circumferentially limited and connected to the rotating shaft 411, the rotating shaft 411 rotates and drives the clamping jaws 413 to rotate, the rotating shaft 411 is rotatably connected to the lifting plate 100, and the rotating shaft 411 rotates to enable the clamping jaws 413 to be switched between a placing state and a clamping state; in the rest state, the clamping jaw 413 is accommodated in the mounting space; in the clamped state, the clamping jaw 413 projects out of the mounting space from the gap.

When the transport of the goods 006 is performed using the transport rollers 330, there may be a phenomenon in which the goods 006 slips on the transport rollers 330. The slippage of the goods 006 on the conveying roller 330 can be effectively prevented by providing the gripping device 400. When the goods 006 are transported from the outside of the lifting plate 100 to the inside of the lifting plate 100, the clamping device 400 is hidden under the conveying rollers 330 without affecting the lateral movement of the goods 006 on the conveying rollers 330.

Because the lifter plate 100 can transport the goods 006 with different sizes, in order to clamp the goods 006 with different sizes firmly, the sliding rails 415 are arranged on the rotating shaft 411 and the lifter plate 100, the rotating shaft 411 is in sliding fit with the lifter plate 100 through the sliding rails 415, and the sliding rails 415 extend in the direction parallel to the conveying rollers 330. In use, if the small goods 006 are clamped, the two sets of rotating shafts 411 are relatively close to each other through the sliding rails 415, so that the clamping space is reduced, and if the large goods 006 are clamped, the two sets of rotating shafts 411 are relatively far away from each other through the sliding rails 415, so that the clamping space is enlarged.

In order to facilitate the worker to manually control the operation of the auto-assembling and disassembling apparatus 001, a control panel 500 is further disposed outside the outer frame 210, and the control panel 500 is electrically connected to the lifting portion 200 and the traverse portion 300.

Through the control panel 500, the worker can autonomously regulate the height position of the lifting plate 100 and regulate the lateral conveyance of the cargo 006 by the traverse section 300.

It should be noted that in other embodiments, the conveying roller 330 of the traverse portion 300 may be replaced by a belt 310 or a caterpillar, and the like, and referring to fig. 6, such a form may increase the force bearing surface with the goods 006 for better load bearing effect, but the installation of the clamping device 400 is no longer convenient.

In other embodiments, the quay 003 may be located below the transport device 002, and in this case, the automatic loading/unloading facility 001 may transport the load at a position lower than the quay 003 to a position higher than the transport device 002, or transport the load at a position higher than the transport device 002 to a position lower than the quay 003.

The application provides an automatic handling equipment 001 can be applied to the unmanned commodity circulation of industrial factory building pier 003 department, through automatic handling equipment 001 with the goods 006 on the eminence pier 003 transport the lifter plate 100 on, transport the carriage height of unmanned commodity circulation car under the pier 003 through lifter plate 100, send into the carriage of unmanned commodity circulation car with goods 006 on the lifter plate 100 again. The problem that the height difference of the industrial factory building wharf 003 is adjusted by using a transportation device 002 such as a forklift 004 by workers is avoided. As shown in fig. 13 and 14, when the manned vehicle 005 is used at the industrial factory building quay 003, the tailboard of the manned vehicle 005 may be laid on the lifting board 100, and the cargo 006 on the quay 003 may be transported into the cabin of the manned vehicle 005 by the lifting board 100 traversing the cargo 006.

Referring to fig. 15, a second embodiment of the present application provides a method for unloading and loading cargo 006 on a quay 003 into a transport device 002 using the transport device 002 and the automatic loading and unloading equipment 001 provided in the first embodiment, including:

s101: the transport device 002 initiates a docking command to the wireless communication unit 235 electrically connected to the lift driving device 230.

S102: the lifting driving device 230 drives the lifting plate 100 to ascend to the wharf 003 height.

S108: the traverse section 300 transports the cargo 006 to the vehicle compartment near the transport device 002 as shown in fig. 12.

By the automatic loading and unloading method, the goods 006 can be automatically butted and transferred between the goods 006 at the high position on the wharf 003 and the transportation device 002 at the low position under the wharf 003 without manual allocation.

In step S105, it is necessary to automatically determine the position of the cargo 006 on the bearing surface 101 to start and stop the traverse unit 300, and therefore, it is necessary to:

s105 a: the first sensor 351 of the lift plate 100 near the first opening 211 senses the entry of the cargo 006 into the load surface 101.

S105 b: the first sensor 351 sends a command to the traverse 300 to activate the traverse 300.

S105 c: the wireless communication unit 235 sends an instruction to the forklift 004 to drive the forklift 004 to unload goods;

s105 d: the traverse section 300 transports the cargo 006 toward the position of the second opening 213 until the cargo 006 is sensed by the second sensor 355 on the lifting plate 100 near the second opening 213.

S105 e: the second sensor 355 sends an instruction to the traverse 300 to stop the traverse 300.

Since the traverse section 300 can carry the cargo 006 only to the end of the carriage after the robot 001 is docked with the carriage of the transporter 002, the method further includes the following steps after step S108:

s109: the cargo transport portion in the vehicle compartment transports the cargo 006 transported by the traverse portion 300 to a predetermined position in the vehicle compartment.

Wherein, the shipment transportation portion can be the inclined plane of carriage bottom, through the slowly stretching out of sliding to the carriage of self gravity of goods 006. It is also possible to provide rollers at the bottom of the car, which can be driven, to drive the goods 006 to a preset position.

In order to avoid the traverse portion 300 from continuously idling after the cargo 006 is carried out, the step S108 includes:

s108 a: the second sensor 355 on the lifting plate 100 near the second opening 213 senses the transport of the cargo 006.

S108 b: the second sensor 355 sends an instruction to the traverse 300 to stop the traverse 300.

When the forklift 004 transports the goods 006 on the dock 003 to the carrying surface 101, the transportation device 002 also needs to complete the butt joint with the automatic loading and unloading equipment 001 in time, so as to avoid that the transportation device 002 cannot take the goods 006 when the goods 006 are transported out of the lifting plate 100. Therefore, step S106 further includes:

s106 a: the transport unit 002 is adjacent to the auto-handler 001.

S106 b: the docking sensor of the robot 001 senses the attitude of the transporter 002.

S106 c: when the posture of the transport device 002 meets the butt joint requirement, the carriage of the transport device 002 is opened.

S106 d: the transport unit 002 sends a seating command to the wireless communication unit 235.

Since the docking of the transport unit 002 and the robot 001 needs to ensure a proper interval and also needs the transport unit 002 to have a reasonable posture toward the lifting plate 100. Therefore, after S106a, it is necessary to include a step for repeatedly adjusting the posture of the transportation device 002:

s106 a': when the posture of the transport device 002 does not satisfy the docking request, the transport device 002 is separated from the automatic handling equipment 001, and the process returns to step S106 a.

In summary, a method for automatically loading and unloading goods, which can cope with most problems in the process of automatically loading and unloading goods, comprises the following steps at the end of an automatic loading and unloading goods device:

the transportation device 002 starts a docking instruction to the wireless communication unit 235 electrically connected to the elevation driving device 230;

the lifting driving device 230 drives the lifting plate 100 to ascend to the wharf 003 height;

the wireless communication unit 235 sends a start loading instruction to the transport device 002 and the forklift 004;

the forklift 004 sends the goods 006 on the wharf 003 to the bearing surface 101 to contact with the cross sliding part 300;

the first sensor 351 on the lifting plate 100 near the first opening 211 senses that the cargo 006 enters the bearing surface 101;

the first sensor 351 sends an instruction to the traverse 300 to activate the traverse 300;

the wireless communication unit 235 sends an instruction to the forklift 004 to drive the forklift 004 to unload goods;

the traverse section 300 transports the cargo 006 to the position of the second opening 213 until the cargo 006 is sensed by the second sensor 355 on the lifting plate 100 near the second opening 213;

the second sensor 355 sends a command to the traverse 300 to stop the traverse 300, and the traverse 300 transports the cargo 006 on the bearing surface 101 to the position entirely on the bearing surface 101;

the transportation device 002 is transported to a position below the wharf 003 and butted with the automatic loading and unloading equipment 001;

the lifting plate 100 is lowered to a height to abut against the transport device 002;

the traverse section 300 transports the cargo 006 to the carriage near the transport device 002;

the second sensor 355 on the lifting plate 100 near the second opening 213 senses the transport of the cargo 006;

the second sensor 355 sends an instruction to the traverse 300 to stop the traverse 300.

Accordingly, a method for handling a plurality of problems during a process of loading/unloading a load onto/from a transport unit 002 includes the steps of:

starting a docking instruction of the transportation device 002 to the wireless communication unit 235 electrically connected to the lifting driving device 230;

the transport device 002 is close to the automatic handling equipment 001;

the docking sensor of the automatic handling equipment 001 senses the attitude of the transporter 002;

when the posture of the transport device 002 meets the butt joint requirement, the carriage of the transport device 002 is opened; when the posture of the transport device 002 does not meet the butt joint requirement, the transport device 002 is far away from the automatic handling equipment 001, and the transport device 002 returns to be close to the automatic handling equipment 001;

the transporter 002 sends a seating command to the wireless communication unit 235;

the cargo transport portion in the vehicle compartment transports the cargo 006 transported by the traverse portion 300 to a predetermined position in the vehicle compartment.

The automatic loading and unloading method can be applied to unmanned logistics at the wharf 003 of an industrial factory building, goods 006 on the high wharf 003 are conveyed to the lifting plate 100 through the automatic loading and unloading equipment 001, the height of a carriage of an unmanned logistics vehicle under the wharf 003 is conveyed through the lifting plate 100, and the goods 006 on the lifting plate 100 are conveyed into the carriage of the unmanned logistics vehicle. The problem that the height difference of the industrial factory building wharf 003 is adjusted by using a transportation device 002 such as a forklift 004 by workers is avoided. And the opening and closing of the traverse portion 300 and the opening and closing of the lifting driving device 230 are realized by the communication butt joint of the unmanned logistics vehicle and the automatic loading and unloading equipment, thereby really realizing the unmanned operation.

In addition, other changes may be made by those skilled in the art within the spirit of the present application, and it is understood that such changes are encompassed within the scope of the present disclosure.
