The height and viewing angle of the second camera sensor 3-15 are made adjustable as the length and tilt angle of the telescopic tilt angle bracket 3-6 are changed.
In the case that the target cargo cannot be picked up by the mechanical arm 3-11, the cargo recognition and pickup device 1-8 of the embodiment pushes the target cargo to an inclined state by the retractable pushing support 3-5, adjusts the mechanical arm 3-11 to the inclined state, so as to hold the bottom of the target cargo by the clamping jaw 3-13 of the mechanical arm 3-11, and returns the target cargo to a horizontal state after the target cargo is successfully picked up, so as to complete the pickup of the target cargo. The principle is as follows: for the goods with smaller top view area, the goods usually have smaller weight, and after the mechanical arms 3-11 at the two sides of the goods are extended, the goods can be directly clamped and lifted, and the picking process is finished. For an object with a large visual angle area, a visual angle focal plane image of the object is a parallelogram (an actual cargo plane is a rectangle, and an actual cargo is a cuboid) and usually has large weight, the mechanical arm 3-11 tries to clamp the cargo first, and if the surface friction force of the mechanical arm 3-11 is not enough to clamp the cargo, the telescopic pushing support 3-5 controls the pushing fulcrum 3-16 to push the cargo, namely, one cargo (cuboid) rotates for a certain angle by taking a bottom edge as an axis. Then the tiltable angle fixing surface 3-9 is adjusted to make the plurality of groups of parallel and telescopic mechanical arms 3-11 keep parallel with the side surface of the cuboid. And controlling the mechanical arm 3-11 close to the lifted side of the goods to extend until the clamping jaws 3-13 below the mechanical arm 3-11 on the lifted side of the goods are opened by 90 degrees, and clamping the goods inwards. Then, the height of the second end 1-10 (not shown in fig. 3) of the second cantilever 1-7 in the vertical direction is controlled to lift the cargo identification and pickup device 1-8 upwards for a certain distance, after the cargo is suspended and stopped, the other side mechanical arm 3-11 is controlled to extend, and the clamping jaw 3-13 of the other side mechanical arm 3-11 is opened for 90 degrees, so as to clamp the cargo inwards. And finally, adjusting the inclinable angle fixing surfaces 3-9 to keep the goods horizontal, and finishing the picking process.
The process of picking up the target cargo specifically comprises the following steps:
the position of each cargo in the image collected by the first camera sensor is different, the central point of the collected image is right below the first camera sensor, and the cargo closest to the central point in the image is the cargo closest to the cargo identification and pickup device 1-8, namely the target cargo.
The automatic sorting apparatus allows the goods recognition and pickup device 1-8 of the present embodiment to reach directly above the target goods by rotating the first suspension arm 1-5 (not shown in fig. 3) and slidably suspending the slider 1-6 (not shown in fig. 3).
The distance to the target load is measured by the camera and the distance sensor among the distance sensors 3-14, and the automatic sorting apparatus lowers the load recognition and pickup device 1-8 to a predetermined working height by adjusting the height of the second end 1-10 (not shown in fig. 3) of the second arm 1-7 in the vertical direction according to the measured distance.
The edge of the target cargo to be detected is detected from above the target cargo through the first camera sensor, and the rotation angle of the rotatable fixing surface 3-3 in the horizontal direction is adjusted to adjust the mechanical arm 3-11 to the direction suitable for picking up the target cargo. The multiple groups of parallel and telescopic mechanical arms 3-11 move in the mechanical arm moving tracks 3-10 to reach the edge of the target cargo, the interval between the mechanical arms 3-11 in the same group is equal to the width of the target cargo, the mechanical arms 3-11 extend downwards, the second camera sensors 3-15 descend synchronously, the second camera sensors 3-15 start to work, and at the moment, the second camera sensors 3-15 are used for detecting the lower edge of the target cargo. When the pickup end of the robot arm 3-11 descends to the lower edge of the target cargo, the robot arm 3-11 stops the downward elongation and tries to pick up the target cargo.
And if the pressure between the mechanical arm 3-11 and the target cargo sensed by the pressure sensor 3-12 reaches a pressure threshold value, lifting the target cargo by using the friction force between the mechanical arm 3-11 and the target cargo. The position change of the lower edge of the target cargo can be detected by the second camera sensors 3-15 to determine whether the target cargo is lifted successfully, if the lower edge of the target cargo is still at the original position, it indicates that the target cargo cannot be lifted, and if the lower edge is lifted, it indicates that the target cargo is lifted.
If the target cargo fails to be lifted, indicating that the target cargo is too heavy, the robot arm 3-11 leaves the clamped state and is away from the target cargo by a distance (which may be preset). The telescopic pushing supports 3-5 are controlled to move in the pushing device moving tracks 3-4, the target goods are pushed to be in an inclined state through the telescopic pushing supports 3-5, and in the process, the second camera sensors 3-15 can detect the inclination angle of the target goods.
And adjusting the multiple groups of mechanical arms 3-11 to reach an inclined state the same as the inclined angle of the target goods, supporting the bottom of the lifting side of the target goods by using the clamping jaws 3-13 of the mechanical arms 3-11 on one side, supporting the bottom of the other side of the target goods by using the clamping jaws 3-13 of the mechanical arms 3-11 on the other side after the target goods are lifted to enable the target goods to leave the contacted plane, and then restoring the target goods to be horizontal to finish the picking of the target goods. In the process, the position change and the inclination angle change of the target cargo are detected through the second camera sensor 3-15, and the positions of the mechanical arm 3-11 and the clamping jaw 3-13 are detected.
When the cargo recognition and pickup device 1-8 picks up the target cargo, the telescopic pushing support 3-5 can push the target cargo to an inclined state from the upper side or the side of the target cargo, wherein when the telescopic pushing support 3-5 pushes the target cargo from the upper side of the target cargo, the telescopic pushing support 3-5 is positioned above the target cargo and is far away from one side of the second camera sensor 3-15; when the telescopic pushing support 3-5 pushes the target cargo from the side of the target cargo, the telescopic pushing support 3-5 is located at the side of the target cargo and is located at the same side as the second camera sensor 3-15. Accordingly, the side where the target cargo is lifted up is made to be the side close to the second camera sensor 3-15, so that the second camera sensor 3-15 detects a change in the position and a change in the tilt angle of the target cargo, a change in the positions of the robot arm 3-11 and the gripper 3-13, and the like.
Fig. 4(a) and 4(b) are schematic diagrams illustrating that the telescopic pushing support of the embodiment pushes a large piece of target cargo to rotate. The large piece of the embodiment mainly means a heavy weight, and the goods usually have a large volume. Fig. 4(a) is a schematic view showing that the telescopic pushing support 3-5 pushes the target cargo from above, and when the telescopic pushing support 3-5 pushes the cargo from above the target cargo, a pushing force is generated at the pushing fulcrum 3-16 by extending the telescopic pushing support 3-5; fig. 4(b) is a schematic view showing that the telescopic pushing bracket 3-5 pushes the target cargo from the side of the target cargo to rotate, and when the telescopic pushing bracket 3-5 pushes the cargo from the side of the target cargo, a pushing force is generated at the pushing fulcrum 3-16 by moving the telescopic pushing bracket 3-5 in the pushing means moving track 3-4.
The goods identification and pickup device 1-8 of the embodiment identifies the target goods after picking up the target goods, and mainly identifies the tag information of the target goods. The label information is, for example, bar code information. The cargo identification process is described below.
In the case where the tag is located above the target cargo, the tag information of the target cargo may be directly recognized by the first camera sensor of the camera and distance sensors 3 to 14.
In the case that the tag is not above the target cargo, the rotatable stationary plane 3-3 is adjusted while the second camera sensor 3-15 on the retractable tilt angle bracket 3-6 starts to recognize the tag information at the side of the target cargo. If no label information is recognized from each side surface, which indicates that the label of the target cargo is positioned at the bottom, the inclination angle of the telescopic inclination angle bracket 3-6 is adjusted and the telescopic inclination angle bracket 3-6 is extended, so that the second camera sensor 3-15 can shoot the bottom of the cargo to recognize the label information of the bottom of the target cargo.
Fig. 5 is a schematic top view of an automated sorting apparatus in a sorting area according to one embodiment of the present invention.
As shown in fig. 5, the sorting device comprises sorting areas 5-1 distributed in a circle, wherein the sorting areas 5-1 are centered at inner cylinders 2-2 of the automatic sorting device, and comprise a storage area for goods to be sorted (see the upper half part of the sorting area 5-1 in fig. 5) and a storage area for the sorted goods (see the lower half part of the sorting area 5-1 in fig. 5), and different areas belong to different angle (i.e. angle coordinates in polar coordinates) intervals, so that dynamic setting and adjustment are facilitated. Fig. 5-2 shows a truck for transporting sorted goods, which reserves a position for parking the truck 5-2 when the sector angle of the sorted goods storage area is configured.
The automatic sorting equipment provided by the embodiment of the invention can be provided with N rotatable suspension devices, wherein N is any integer between 1 and 8. Fig. 5 shows, by way of example only, a top view of a rotatable suspension of the automatic sorting device, which top view comprises the first suspension arm 1-5 and the suspended slider 1-6. The automatic sorting apparatus recognizes a label of a target cargo by using a cargo recognition and pickup device 1-8 (not shown in fig. 5) on a rotatable suspension device and picks up the target cargo according to its polar coordinate position, calculates a polar coordinate of a designated sorting position to which the target cargo is finally sorted according to a sorted cargo storage area to which the target cargo should be sorted and a volume size of the target cargo, and finally places the target cargo at the designated sorting position.
The goods picking process comprises the following steps: and placing the goods to be sorted in the goods storage area to be sorted. When the rotatable suspension device moves above the goods storage area to be sorted, the goods identification and pickup device 1-8 starts to work to locate the target goods to be picked up (using the camera sensor on the goods identification and pickup device 1-8 to locate the target goods), and controls the current rotatable suspension device (i.e. the rotatable suspension device shown in the top view of fig. 5) to pick up the located target goods. The first boom 1-5 is suspended from rotating during the picking of the goods to avoid unsuccessful picking of the goods. The sub-suspension devices (including the suspension sliders 1-6, the second suspension arms 1-7, the goods identification and pickup devices 1-8) (not shown in fig. 5) on the other rotatable suspension devices (not shown in fig. 5) can still continue to operate. After the rotatable suspension device carries the target goods to reach the designated height, the target goods move along with the first cantilever 1-5 and are conveyed to the sorted goods storage area for placement.
The goods placing process comprises the following steps: the first boom 1-5 to the designated sorting location of the sorted goods storage area, the rotatable suspension device starts to simultaneously lower and move the target goods. When the volume of the target goods is larger, the target goods can be placed in the direction that the radius of the sorted goods storage area is close to the edge, and when the volume of the target goods is smaller, the target goods can be placed in the direction that the radius of the sorted goods storage area is close to the circle center (namely, the radius coordinate of the polar coordinate). Specifically, the designated sorting location to which the target goods are finally sorted is determined as follows: the method comprises the steps of firstly determining a target sector corresponding to target goods in a sorted goods storage area, and then determining the position of a radial distance corresponding to the volume of the target goods in the target sector, wherein the volume of the target goods and the target sector are determined according to label information of the target goods identified by the goods identification and pickup device 1-8. Therefore, the embodiment of the invention realizes automatic tallying according to different volumes. The freight train that waits to the loading also stops near the outside region of the radius in the district is deposited to the goods of having sorted, conveniently carries out follow-up loading.
When the rotatable suspension device is used for placing goods, the first cantilever 1-5 can also pause to rotate so as to avoid errors in the position for placing the goods, and the sub-suspension devices on other rotatable suspension devices can still continue to work at the moment.
When the ground surface of the area occupied by the goods in the sorted goods storage area is full, the rotatable suspension device can superpose and place new goods on the upper layer of the existing goods, so that the occupied space is reduced. And when the height of the goods reaches the minimum working height of the rotatable suspension device, the sorting of the goods corresponding to the sorted goods storage area is suspended. The minimum working height of the rotatable suspension means the maximum height of the second end 1-10 (not shown in fig. 5) of the second boom 1-7 of the rotatable suspension in the vertical direction from the ground of the sorting area 5-1.
And finishing the whole automatic sorting process when all the goods are sorted. The embodiment of the invention determines the position of the goods to be sorted by utilizing the polar coordinates (including sector angles and radial distances), and puts the goods on different polar coordinate radius axes according to the volume of the goods by utilizing the characteristics of the polar coordinates. The change of goods and the temporary storage area can be well coped with. The rotatable suspension device (comprising the goods identification and pickup device 1-8) is used for simulating a manual sorting and carrying mode, so that manual intervention is reduced, and unmanned sorting and carrying are realized. In addition, the embodiment of the invention does not need a conveyor belt, and has the advantages of low cost, high sorting speed and the like compared with a sorting scheme such as a sorting robot with a stepping device and a robot arm.
In the whole automatic sorting process, the automatic sorting equipment provided by the embodiment of the invention is controlled to work by a background control system. A control method and a control system of the automatic sorting apparatus according to the embodiment of the present invention will be described in detail below.
Fig. 6 is a schematic view of main steps of a control method of an automatic sorting apparatus according to one embodiment of the present invention.
The control method of this embodiment may be executed by a background control system (control system for short) that controls the automatic sorting device, and the control system may be specifically located on a server or a terminal. The control method of the automatic sorting apparatus of the present embodiment mainly includes steps S601 to S604 as follows.
Step S601: and controlling the goods identification and pickup device to pick up the target goods and identify the label information of the target goods.
Step S602: and obtaining the volume of the target goods and the target sector of the target goods corresponding to the sorted goods storage area according to the label information.
Step S603: and determining the position of the radial distance corresponding to the volume of the target goods in the target sector as the designated sorting position according to the preset corresponding relation between the volume of the goods and the radial distance of each position in the sector.
Wherein, the radial distance of a position in a sector refers to the distance from the position to the center of a circle of a sorting area 5-1, the sorting area is a circular distribution area comprising a storage area for goods to be sorted and a storage area for the sorted goods, and the rotatable suspension device can rotate around the position right above the center of the circle of the sorting area.
Step S604: the control transmission device drives the rotatable suspension device to rotate, so that the rotatable suspension device sorts the target goods to the designated sorting position.
Specifically, the control system can control the transmission device 1-2 to drive the first cantilever 1-5 of the rotatable suspension device to rotate, so that the rotatable suspension device can carry and place the target goods to the designated sorting position to complete sorting.
The control method of this embodiment further includes, before step S601, configuring in advance start and stop angles corresponding to sectors included in each of the storage areas for the goods to be sorted and the storage areas for the sorted goods, and configuring a corresponding relationship between a radial distance of each position in each sector of the storage areas for the sorted goods and a volume of the goods.
The automatic sorting apparatus of the present embodiment may be configured with a plurality of rotatable suspensions, and in the case where two or more rotatable suspensions are configured, the control system further includes, before controlling the first boom 1 to 5 of one of the rotatable suspensions to rotate: determining that the rotatable suspension device to be controlled has been assigned turning control. The rotatable suspension can only be rotated by the transmission 1-2 if the rotatable suspension is assigned rotational control.
The control method of the automatic sorting apparatus of the present embodiment is explained in detail below based on the structure of the embodiment shown in fig. 1 to 3.
And (3) picking and positioning:
the first cantilever 1-5 waits for a background control system (control system for short) to distribute the rotation control right of the rotatable suspension device to which the first cantilever belongs; when the first cantilever 1-5 determines to obtain the rotation control right, the control system starts a top camera sensor (namely a first camera sensor) in the goods identification and pickup device 1-8. The top camera sensor obtains the position of the target cargo closest to the top camera sensor, and the control system obtains the angle difference between the angle of the first cantilever 1-5 and the angle of the target cargo according to the position of the target cargo. The control system controls the transmission device to drive the rotatable suspension device to rotate around the position right above the circle center of the sorting area, and the circle center of the sorting area is the position point of the intersection of the upright post 1-1 and the plane of the sorting area. The rotatable suspension device rotates around the right upper part of the circle center of the sorting area, namely, the rotatable suspension device rotates by taking the upright post 1-1 as an axis. Specifically, the control system starts the transmission device 1-2 to drive the outer-layer cylinder 2-1 of the upright post 1-1 to rotate, so that the first cantilever 1-5 rotates to the angle of the target goods.
Then, the control system controls the transmission device 1-2 to stop driving the outer layer cylinder 2-1 of the upright post 1-1 to rotate, according to information collected by the top camera sensor, the control system can obtain the distance difference between the suspension sliding block 1-6 on the first cantilever 1-5 and the position of the target cargo, and the control system starts the suspension sliding block 1-6 to move to the position right above the target cargo.
And (3) picking up:
the rotatable suspension device has no control over the rotation of the picking device, i.e. the first suspension arm 1-5 is not rotatable, so as to avoid unsuccessful picking.
The control system obtains the height difference between the cargo identification and pickup device 1-8 and the target cargo according to the top camera sensor and the distance sensor, and controls the foldable second suspension arm 1-7 between the cargo identification and pickup device 1-8 and the suspension slide block 1-6 to descend to a preset working height according to the height difference.
After the second cantilever 1-7 reaches a preset working height, the top camera sensor detects the edge of the target cargo, and the control system controls the multiple groups of parallel and telescopic mechanical arms 3-11 to move in the horizontal direction, so that the positions between the same group of mechanical arms 3-11 with the same width as the target cargo are reached. The pick-up end of the mechanical arm 3-11 descends synchronously with the side camera sensor (i.e. the second camera sensor 3-15), and the side camera sensor starts to work at the same time.
When the side camera sensor detects the lower edge of the target cargo, the control system stops and the robot arm 3-11 extends (i.e., stops the cargo picking end from moving). The robot arms 3-11 on both sides of the target cargo attempt to pick up the target cargo. When the pressure detected by the pressure sensor 3-12 inside the robot arm 3-11 reaches a predetermined pressure threshold, the control system stops the gripping action of the robot arm 3-11. The control system controls and adjusts the folding angle of the second cantilever 1-7 to try to lift the target goods, and if the side camera sensor does not detect that the side of the second cantilever changes to the lower edge of the target goods (indicating that the lifting of the target goods is unsuccessful, the second cantilever is not lifted and the target goods are too heavy), the control system controls the mechanical arms 3-11 on the two sides of the target goods to leave the clamping state and leave the target goods to reach a certain distance threshold value.
The control system controls the telescopic pushing support 3-5 to increase pressure on the edge of the target cargo (the edge increasing the pressure is opposite to the direction of the side camera sensor, so that the camera sensor can monitor the subsequent positions of the clamping jaws 3-13 conveniently). When the side camera sensor detects that the target cargo is rotated to a preset angle, the control system controls the telescopic pushing supports 3-5 to stop working.
The control system controls the control angle cable above the tiltable angle fixing surface 3-9 to change the length so that the tiltable angle fixing surface 3-9 rotates in the vertical direction, thereby driving the mechanical arm 3-11 to tilt, and controls the tiltable angle fixing surface 3-9 to stop rotating after the tilt angle of the mechanical arm 3-11 is the same as that of the target cargo.
The control system controls the mechanical arm 3-11 on the side lifted by the target cargo to descend to the target cargo suspension area. When the side camera sensor detects that the clamping jaws 3-13 reach the suspended area at the lower edge of the target goods on the lifted side, the control system stops the descending of the side mechanical arm 3-11. The control system controls the mechanical arm 3-11 to clamp the target goods and ascend, and when the side detection of the side camera sensor reaches the state that the clamping jaw 3-13 is overlapped with the lower edge of the target goods (at the moment, the side clamping jaw 3-13 holds the target goods), the control system stops the ascending of the mechanical arm 3-11 (the ascending refers to the shortening length of the mechanical arm 3-11 which is stretched before).
The control system controls the foldable second suspension arm 1-7 between the goods identification and pickup device 1-8 and the suspension sliding block 1-6 to lift the target goods. When the folding angle in the folding booms reaches a predetermined first angle threshold, the control system controls the second booms 1-7 to suspend raising the target cargo. The control system controls the control angle cable above the tiltable angle fixing planes 3-9 to change the length to adjust the target cargo to a horizontal state.
The control system controls the other side mechanical arm 3-11 to descend (i.e. extend), and when the clamping jaw 3-13 of the other side mechanical arm 3-11 reaches the lower edge of the target cargo, the other side mechanical arm is also detected by the side camera sensor and fed back to the control system. The control system controls the other side arm 3-11 to stop descending (extending) and start ascending (shortening). When the side camera sensor detects that the clamping jaws 3-13 are overlapped with the lower edge of the target cargo, the control system stops the other side mechanical arm 3-11 from rising (shortening) so that the clamping jaws 3-13 of the other side mechanical arm 3-11 support the target cargo. The control system controls the foldable second cantilever 1-7 to lift the target cargo, and when the folding angle reaches a predetermined second angle threshold, the lifting is stopped.
The control system controls the overhead camera sensor to attempt to identify the target cargo tag (i.e., the tag information of the target cargo) of the logistics above the target cargo. If the label is not identified, the control system controls the rotatable fixing surface to rotate for 360 degrees 3-3, and the side camera sensor searches for the label on the side of the target cargo in the rotating process. If the side face is not recognized, the control system controls the telescopic inclination angle support 3-6 to a certain angle, and enables the telescopic inclination angle support 3-6 to extend, so that the side face camera sensor reaches the position below the lower edge of the target goods, and the side face camera sensor recognizes the label of the target goods at the bottom of the target goods.
And after the target cargo tag is identified, the target cargo tag is transmitted back to the control system through the network device. The control system controls the retractable reclining braces 3-6 that retract the sides.
After the picking is finished, the first cantilever 1-5 waits for the control system to distribute the rotation control right of the rotatable suspension device to perform subsequent calculation and placement.
Cargo conveying and placing processes:
the control system obtains the destination and the volume of the target goods in a logistics subsystem (a system for storing information) according to the label of the target goods sent by the automatic sorting equipment. And the control system inquires the starting and stopping angle of the sector where the destination is located in a local database of the control system according to the destination. The control system inquires the distance corresponding to a central point (the larger the volume is, the farther the distance is) in a local database of the control system according to the volume of the target goods, wherein the central point is the center of the sorting area 5-1, namely the installation position of the inner-layer cylinder 2-2 in the sorting area 5-1, and the distance corresponding to the central point at a certain position is the distance from the position to the center of the sorting area 5-1.
After the control system distributes the rotation control right of the rotatable suspension device, the transmission device 1-2 is started to drive the first cantilever 1-5 to move to the designated sector (namely the target sector corresponding to the target goods in the sorted goods storage area) according to the obtained angle range and distance, and the goods identification and pickup device 1-8 is enabled to convey the target goods to the position right above the designated sorting position. The control system inquires the local database information and finds the angle and the distance of the lowest point in the height of the placed goods (the height of the placed goods can be obtained by the side camera sensor) within the specified distance of the specified sector. The control system controls the first boom 1-5 to move to an angle above the lowest point, and stops the first boom 1-5 from rotating (the rotatable suspension device does not have rotation control).
The control system controls the suspension sliding blocks 1-6 on the first suspension arms 1-5 to slide to the positions corresponding to the distance from the lowest point to the central point, and controls the foldable second suspension arms 1-7 to descend the target cargo to the designated height. The control system controls the mechanical arms 3-11 to gradually release and gradually separate (so as to prevent the target cargos from being damaged by excessive vibration), so that the target cargos are placed in a radial distance corresponding to the volume of the target cargos in a target sector, and the lowest height of the placed cargos is achieved.
The control system then controls the second foldable cantilever arms 1-7 to be reset. The control system updates the height of the placement position in the database. The control system releases the state that the outer cylinder 2-1 of the automatic sorting equipment is not rotatable, and other rotatable hanging devices can obtain the rotation control right.
The control method of the automatic sorting equipment can control the automatic sorting equipment to automatically position, pick up, transport and place the goods, so that the automatic sorting of the goods is completed, the manual intervention is reduced, the dynamic and flexible setting of the sorting starting and stopping positions is realized, and the many-to-many automatic sorting can be realized. It will be appreciated by those skilled in the art that some of the alternative embodiments of the automated sorting apparatus mentioned above for the embodiment of fig. 1 may also be controlled with reference to the above-described method.
