Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a first embodiment, as shown in fig. 1, the system for autonomous goods distribution based on internet of things provided by the present invention includes: a self-service cabinet 100, a distribution vehicle 200, and at least one delivery vehicle 300.
As shown in fig. 2 to 4, the self-service cabinet 100 has a plurality of cells 100a arranged horizontally and vertically, and each cell 100a has a second turnaround box 110. The front and back surfaces of the second transfer case 110 are provided with iron sheets 111, and the inside of the cell 100a is provided with an electromagnetic plate (not shown) magnetically attracted to the iron sheets 111 on the back surface of the second transfer case 110 and an eject mechanism (not shown) for ejecting the second transfer case 110 from the cell 100 a.
When the second transfer box 110 is placed in the cell 100a, the electromagnetic plate is electrified to generate a certain magnetism, so that the iron sheet 111 on the back surface of the second transfer box 110 is attracted and fixed, and meanwhile, the iron sheet 111 presses the ejection mechanism, so that the ejection mechanism is in a compressed state. When the electromagnetic plate is de-energized, the second rotating box 110 is ejected from the cell 100a by a certain distance by the elastic force of the ejection mechanism.
In this embodiment, the ejection mechanism is comprised of a plurality of springs arranged side-by-side. An accommodation groove 100b is provided in the cell 100a, and a plurality of springs are disposed in the accommodation groove 100 b. The number of the electromagnetic plates is two, and the two electromagnetic plates are respectively arranged in the mounting grooves 100c at two sides of the accommodating groove 100 b. When the second circulation box 110 is pushed into the cell 100a, the two electromagnetic plates will attract the iron sheet 111 in the second circulation box 110 and press the spring in the receiving slot 100 b.
In order to prevent the spring from being ejected out of the receiving groove 100b, one end of the spring is fixed in the receiving groove 100 b.
The self-service cabinet 100 is further provided with a touch screen 120, and a user can operate the touch screen 120 to pick up goods. The picking process is the same as the picking process of the conventional self-picking cabinet 100. For example, a user may unlock a corresponding electromagnetic plate by entering a pick code. After the unlocking, the power of the electromagnetic plate is cut off, the ejection mechanism ejects the second circulation box 110 outwards for a certain distance, so that the user can grab the side wall of the second circulation box 110, further pull the second circulation box 110 out of the cell 100a, take out the goods in the second circulation box 110, and push the second circulation box 110 into the cell 100a again after the goods taking is completed.
To ensure that the user can quickly suction-fix the second transfer cassette 110 when pushing the second transfer cassette 110 into the cell 100 a. The surface of the unit cell 100a opposite to the back surface of the second transfer box 110 is provided with a distance sensor, and when an object is sensed by the distance sensor to approach, the power of the electromagnetic plate is turned on again, so that the electromagnetic plate generates magnetism, and thus when a user pushes the second transfer box 110, the second transfer box 110 can be fixed in the unit cell 100a in an attracting manner.
In addition, the electromagnetic plate can also be automatically powered on within a set time after being powered off, for example, after 5S after the electromagnetic plate is powered off, the electromagnetic plate is automatically connected to the power supply circuit, so that the magnetism of the electromagnetic plate is recovered. The user can draw the electromagnetic plate out of the induction range of the magnetic attraction of the electromagnetic plate within 5S. When the user pushes the empty second circulation box 110 into the cell 100a to a certain extent, the electromagnetic plate automatically attracts the empty second circulation box 110 to move further into the cell 100a, thereby fixing the cell 100a by suction.
Preferably, on the basis of the above embodiment, two sliding grooves 110a are provided at the bottom of the second rotating box 110, a guide plate 130 is provided in the cell 100a of the self-service cabinet 100, and a guide rail corresponding to the sliding groove 110a is provided on the guide plate 130. By providing the guide plate 130, the second transfer box 110 can be guided to a certain extent, so that the second transfer box 110 can slide more smoothly in the cell 100a, the ejection structure is convenient to eject the second transfer box 110 out of the magnetic induction range of the electromagnetic plate, and even after the magnetic plate is restored to be magnetic, the user can smoothly pull out the second transfer box 110 from the cell 100 a. And, it is also convenient for the user to withdraw the second transfer box 110 from the cell 100 a.
Further, in the above embodiment, a plastic plate made of PTFE material is used as the guide plate 130. The plastic plate made of PTFE material has low friction and good wear resistance, so that the second transfer box 110 can slide more smoothly, and the wear of the second transfer box 110 is reduced. While also facilitating subsequent magnetic actuation of the second transfer cassette 110.
Still further, in addition to the above-described embodiment, a first magnet 112 may be provided at the bottom of the second transfer case 110, and a second magnet opposite to the first magnet 112 may be provided on the guide plate 130. The first magnet 112 and the second magnet have the same magnetic pole on opposite sides, thereby causing the first magnet 112 and the second magnet to generate repulsion. The pressure applied by the second transfer box 110 between the guide plates 130 is further reduced by the repulsive force between the first magnet 112 and the second magnet, thereby further reducing the frictional force between the second transfer box 110 and the guide plates 130. When there are many commodities stored in the second transfer box 110, the second transfer box 110 can still keep smooth sliding, and the user experience is improved. Meanwhile, the efficiency of driving the second transfer cassette 110 to move by the magnetic force is further improved.
As shown in FIGS. 5 to 8, the distribution vehicle 200 has a container 210, and a storage area 210a, an activity area 210b and a storage area 210a are provided in the container 210 in parallel in this order. During distribution, the delivery trolley 300 moves into the active area 210b of the container 210, and the delivery trolley 300 is transported to the destination area by the distribution vehicle 200 together with the first turnaround box 231.
Each storage area 210a is provided with a storage 230, the storage 230 has a plurality of storage compartments 230a arranged in a horizontal and vertical manner, and each storage compartment 230a can store a first rotating box 231 to be dispensed. After the system receives the external order, the goods on the order are sorted into a first turnaround box 231 according to the order information. Then, the system transfers the first turnaround box 231 having the same destination area to the storage compartment 230a of the storage bin 230 of the same delivery cart 200 through the launch vehicle 300.
In the present embodiment, the first turnaround box 231 and the second turnaround box 110 are of the same type, and for convenience of distinction, the turnaround box to be delivered in the delivery vehicle 200 is designated as the first turnaround box 231, and the turnaround box empty in the self-service cabinet 100 is designated as the second turnaround box 110.
In order to reduce the weight of the first and second cassettes 231 and 110 for driving the first and second cassettes 231 and 110 to move by magnetic force, in the embodiment, the first and second cassettes 231 and 110 are made of plastic material such as LCP, PARA, or PEEK, which has light weight, good structural strength, and wear resistance.
Each storage compartment 230a of the storage cabinet 230 is also provided with a guide plate 130 therein, and the guide plate 130 is identical to the aforementioned guide plate 130 for improving the smoothness of sliding of the first rotating box 231 for easy extraction or storage.
Correspondingly, in order to fix the first rotating box 231 or the recovered second rotating box 110, two magnetic plates 232 are disposed inside the cabinet for attracting and fixing the first rotating box 231 or the second rotating box 110.
During delivery, the delivery vehicle 200 transports at least one delivery vehicle 300 to the self-service cabinet 100 in the destination area, and exchanges the first turnaround box 231 in the storage cabinet 230 with the empty second turnaround box 110 in the self-service cabinet 100, thereby realizing the autonomous delivery of the goods from the order placement to the self-service cabinet 100.
The rear of the container 210 is provided with a lifting tail plate 220 which can be turned outward and contacted with the ground, and the lifting tail plate 220 is fixed to the rear of the distribution vehicle 200. It should be noted that the lifting tail plate 220 is substantially the same as the lifting tail plate 220 applied in the existing truck, and the specific structure and action principle thereof are implemented by referring to the existing lifting tail plate 220, in this embodiment, the lifting tail plate 220 is a vertical lifting tail plate 220, which can play a certain role in protecting the tail of the truck.
When the distribution vehicle 200 reaches a target area on a distribution path, cabinet body label data of the self-service cabinet 100 is acquired through the vehicle-mounted omnidirectional active reader-writer, vehicle information of the vehicle and label information of the self-service cabinet 100 of the target area are packaged and sent to a background distribution system through a vehicle-mounted wireless network, a corresponding delivery task is sent to the distribution vehicle 200 through the distribution system according to the vehicle information and the label information of the self-service cabinet 100, and the delivery path is analyzed from the delivery task after the delivery vehicle 200 receives the delivery task information. Finally, as shown in fig. 11-12, the delivery vehicle 200 drives the lifting tail 220 to turn over and contact the ground, and the delivery vehicle 300 is controlled to move back and forth between the self-lifting cabinet 100 and the storage cabinet 230 according to the delivery route, so as to deliver and recover goods.
The throwing trolley 300 is provided with a wireless communication module, the distribution vehicle 200 can control the throwing trolley 300 to throw and recycle according to a throwing route through a vehicle-mounted network, and the working state of the throwing trolley 300 is fed back to the distribution system in real time.
In order to enable the delivery vehicle 300 to follow the delivery route, a designated parking area is set beside the self-service cabinet 100, and during delivery, a delivery driver stops the delivery vehicle 200 in the designated parking area, and plans a path of the delivery vehicle 300 with a point in the designated parking area as a starting point.
After the delivery vehicle 200 is parked in the designated parking area, the positions of the delivery vehicle 200 and the self-service cabinet 100 are determined, and the positions of each storage compartment 230a in the self-service cabinet 100 and each unit cell 100a in the container 210 are determined, so that the movement route of the delivery vehicle 300 from the delivery vehicle 200 to the self-service cabinet 100 can be planned in advance, and after the delivery vehicle 200 reaches the destination area, the delivery vehicle 300 is controlled to deliver the first turnaround box 231 and the second turnaround box 110 according to the planned movement route (i.e., the delivery route described above).
In order to make the planned delivery route more accurate and reduce the deviation of the delivery driver caused by manual parking, in this embodiment, an automatic parking system may be built in the delivery vehicle 200, and accurate parking may be achieved through the automatic parking system. And moreover, the parking information can be sent to the distribution system through the vehicle-mounted wireless network, so that the distribution system can finely adjust the delivery route according to the positioning data in the parking information, and the planned delivery route is more accurate.
In order to determine whether the cart 300 travels along the route, distance sensors 140 and 233 are disposed on the front surfaces of each cell 100a of the self-service cabinet 100 and each storage cell 230a of the storage cabinet 230, and when the cart 300 approaches the storage cell 230a or the cell 100a, the distance sensors 140 and 233 may sense that the cart 300 has reached the loading position or the retrieval position (when the cart 300 takes out the second rotating box 110 empty in the cell 100a, the cell 100a becomes the loading position, and when the cart 300 takes out the first rotating box 231 to be delivered in the storage cell 230a, the cell 230a becomes the retrieval position), so that the cart 300 may be controlled to perform the next loading or retrieval operation.
Since the car of the delivery vehicle 200 is at a certain height from the ground, this has a certain influence on the accuracy of the launch route of the launch vehicle 300. Therefore, in this embodiment, the container 210 is a wing-extended container 210, that is, the two sides of the container 210 have wing-extended plates 211 that can be extended outwards. The storage opening of the corresponding storage cabinet 230 faces the wing expanding plate 211, so that the storage lattice 230a of the storage cabinet 230 is exposed when the wing expanding plate 211 of the freight container 210 is expanded. Thus, the cart 300 can directly carry out the loading work with the ground as a movement reference surface without loading and unloading the container 210. Specifically, the throwing trolley 300 is controlled to move out of the movable area 210b of the container 210 and move towards the penultimate unit cell 100a on the left side of the self-lifting cabinet 100, and the throwing trolley 300 is aligned with the penultimate unit cell 100a on the left side of the self-lifting cabinet 100 through the distance sensor 140. Then, the position of the penultimate cell 100a on the left side of the self-service cabinet 100 is used as the starting point and the end point of the delivery route, and the delivery trolley 300 is controlled to carry out delivery and recovery work according to the delivery route. After all the releasing and recovering operations are finished, the releasing trolley 300 is controlled to move to a position aligned with the penultimate unit cell 100a on the left side of the self-lifting cabinet 100, then the releasing trolley 300 is controlled to return to the distribution vehicle 200, and the distribution vehicle 200 is driven to a corresponding specified parking space of the next target area by a distribution driver to perform new releasing operations.
As shown in fig. 9 to 10, the cart 300 is mainly composed of a moving unit 310, an elevating unit 320, and an exchanging unit 330. The moving part 310 includes a frame, a movable wheel disposed at a bottom of the frame, and a driving mechanism for driving the movable wheel. In order to sense the distance between the cart 300 and other objects (such as the self-service cabinet 100), the circumference of the frame is provided with distance sensors distributed uniformly.
In the present embodiment, the moving portion 310 is substantially identical to the driving structure of the conventional general launch vehicle 300, and therefore, the detailed description thereof is omitted.
The elevating unit 320 includes a cross-type holder 321 and an electric pusher 322, and the cross-type holder 321 is slidably provided at the bottom thereof to the moving unit 310 and slidably provided at the top thereof to a bottom plate 331 of the exchanging unit 330. The fixed end of the electric push rod 322 is pivoted on the moving part 310, and the free end of the electric push rod 322 is pivoted on a horizontal connecting rod of the cross bracket. When the electric push rod 322 extends, the cross-type bracket 321 is driven to extend, so as to raise the height of the exchanging part 330, so that the exchanging part 330 can be aligned with the storage compartment 230a or the unit compartment 100a in the high position. When the electric push rod 322 retracts, the cross-type support 321 is synchronously driven to retract, so that the exchange part 330 is aligned with the lower storage compartment 230a or the unit cell 100 a.
Since the moving unit 310 and the contracted elevating unit 320 have a certain height, the loading and retrieving work is not performed for the cells 100a having a lower height than the sum of the moving unit 310 and the contracted elevating unit 320 in the present embodiment.
The exchanging part 330 includes a bottom plate 331, and the top of the cross-shaped support 321 is slidably coupled to the bottom surface of the bottom plate 331. The top surface of the bottom plate 331 is provided with two linear modules 332, and each linear module 332 is provided with a magnetic attraction plate 333 perpendicular to the bottom plate 331.
When the throwing trolley 300 is positioned below the empty second rotating box 110 according to the planned throwing route, the throwing trolley 300 is extended outwards by controlling the electric push rod 322 to lift the exchanging part 330 to the same height as the empty second rotating box 110, and the driving linear module 332 drives the magnetic adsorption plate 333 to move towards the empty second rotating box 110. After the distance sensor on the cell 100a corresponding to the empty second transfer box 110 senses the magnetic absorption plate 333, the power supply of the electromagnetic plate in the cell 100a is disconnected, the empty second transfer box 110 is ejected by the ejection mechanism for a certain distance, and the magnetic absorption plate 333 drives the empty second transfer box 110 to move to the magnetic absorption plate 333 through magnetic force, so that the empty second transfer box 110 is absorbed on the magnetic absorption plate 333.
After the empty second transfer box 110 is taken out, the throwing trolley 300 moves to align the first transfer box 231 to be distributed with the empty cell 100a, and pushes the first transfer box 231 to move into the cell 100a through another linear module 332, when a distance sensor inside the cell 100a senses that an object is close to the empty cell, the current on the electromagnetic plate is increased, so that the magnetism of the electromagnetic plate is increased, and meanwhile, the current on the magnetic adsorption plate 333 is reduced, so that the first transfer box 231 continues to move into the cell 100a under the action of the magnetic pole of the electromagnetic plate until the first transfer box 231 is adsorbed and fixed on the cell 100 a.
When the first turnaround box 231 is taken out of the storage compartment 230a of the storage 230, the cart 300 is controlled to move along the dispensing route to the opposite side of a locker of the storage 230, and the distance sensor 233 on the front side of the storage compartment 230a in the lowermost row senses which row of storage compartments 230a the cart 300 moves. When the launch vehicle 300 moves the storage compartment 230a in the row where the designated first circulation box 231 is located, the exchange portion 330 is lifted, the magnetic attraction plate 333 is driven to move towards the designated first circulation box 231, the magnetic force of the magnetic attraction plate 333 is increased, the magnetic force is larger than the magnetic attraction force exerted on the first circulation box 231 by the magnetic plate 232 in the storage compartment 230a, and the first circulation box 231 moves towards the magnetic attraction plate 333, so that the first circulation box 231 is taken out.
When the empty second transfer box 110 is stored in the storage compartment 230a of the storage cabinet 230, the principle is similar to the principle of taking out the first transfer box 231 from the storage cabinet 230, that is, the magnetic attraction plate 333 of the exchanging part 330 is first controlled to be aligned with the empty storage compartment 230a, the empty second transfer box 110 is inserted into the empty storage compartment 230a, and after the empty second transfer box is inserted to the limit movement distance of the linear module 332, the magnetism of the magnetic attraction plate 333 is reduced or removed, so that the empty second transfer box 110 can move towards the storage compartment 230a under the action of the magnetic attraction force of the magnetic plate 232 inside the storage compartment 230a and be attracted to the magnetic plate 232.
Preferably, on the basis of the above embodiment, the number of the linear modules 332 on the bottom plate 331 is four, and each magnetic absorption plate 333 corresponds to two linear modules 332, so as to ensure that the turnover box can be driven to move smoothly when being thrown in or recovered.
According to the technical scheme, the delivery trolley 300 is delivered to the self-service cabinet 100 in a target area along with the commodities, then the commodities are automatically delivered from the delivery trolley 200 to the self-service cabinet 100 without people through the delivery trolley 300, and the controlled second turnover box 110 is automatically recovered, so that the labor cost of commodity delivery and turnover box recovery is reduced.
