To facilitate understanding of the present embodiment, an application scenario of the container transfer system disclosed in the embodiments of the present disclosure is first described, and the container transfer system provided in the embodiments of the present disclosure may be applied to a docking process of the robot 11 and the container transfer device 12. As shown in fig. 1, the robot 12 may illustratively be a robot capable of effecting the handling of multiple containers at once.
In a warehouse logistics scenario, in one possible implementation, the cloud server 13 may issue a movement control instruction for the robot 11, where the movement control instruction may be an instruction for controlling the robot 11 to put goods; alternatively, the instruction may be an instruction for controlling the robot 11 to pick up the goods. For example, in a cargo picking scenario, the cloud server 13 may control the robot to move to a container docking position of the container transfer device 12, at this time, the multiple containers on the robot store the cargo to be picked, the container transfer device may transfer the multiple cargo out to wait for picking, at this time, the robot may leave the container docking position to wait for a next instruction sent by the cloud server. For another example, in a cargo warehousing scene, when the cargo box has been transferred to a position waiting for the robot to receive by the cargo box transfer device, the cloud server may control the robot to move to the cargo docking position to pick up the cargo.
Here, the cloud server 13 stores an order pool of warehouse goods, and a robot is called to select goods according to information to be selected of the goods in the order pool; or calling the robot to realize warehousing of the goods according to the information to be warehoused of the goods in the order pond.

Embodiments of the present disclosure provide a container transfer system that includes at least one robot and at least one container transfer device. As can be seen in fig. 2, which is a schematic structural diagram of the robot and the container transfer device when the robot is docked with the container transfer device, the robot and the container transfer device include a robot 11, a container transfer device 12 and a container 23; the container transfer device 12 may include at least one first container transfer mechanism 221, a multi-tier container transfer mechanism 222, a second container transfer mechanism 223 corresponding to each tier of container transfer mechanisms, a lift mechanism 224 corresponding to each second container transfer mechanism, external transport rails 225, a third container transfer mechanism (the third container transfer mechanism includes a lift mechanism 2261 and a tie bar transfer mechanism 2262), and a controller.
Here, the container transfer device 12 may be docked with a plurality of robots 11 simultaneously. For example, the container transfer device 12 may be docked with two robots 11 simultaneously, wherein different first container transfer mechanisms 221 are controlled to transfer containers from different robots 11. For example, a plurality of containers on the robot a are transferred by the first container transfer mechanism a ', and a plurality of containers on the robot B are transferred by the first container transfer mechanism B', and at this time, the first container transfer mechanism a 'and the first container transfer mechanism B' may be respectively disposed at both ends of the container transfer device 12 in the direction in which the containers are conveyed by the multi-layer container conveying mechanism 222, so that the robot a and the robot B may be docked to different container docking positions of the container transfer device 12.
In some embodiments, a plurality of first container transfer mechanisms 221 may be further disposed at two ends of the direction in which the container conveying mechanism 222 conveys the containers. The specific setting manner may be arranged according to an application scenario, and is not specifically limited herein. The number of layers of the box conveying mechanisms 222 in the box transfer device 12 may be arranged according to a specific application, and is not particularly limited.
Reference can be made to fig. 3, which is a schematic structural diagram of the robot. The robot 11 comprises a robot body 211, a gantry 212 and a multi-layer temporary storage mechanism 213; the gantry 212 is mounted on the robot body 211; a multi-deck buffer mechanism 213 is mounted to one side of the gantry 212, and the buffer mechanism 213 may be used to buffer containers.
The robot 11 is configured to move to the cargo box docking position. Here, the container docking position includes a projection position of the temporary storage mechanism on the ground when the robot 11 is docked with the container transfer device 12; alternatively, the position of each layer of the temporary storage mechanism in the space.
The container transfer device 12 is configured to transfer a plurality of containers on different levels of the buffer mechanism of the robot, which are moved to the container docking station, onto the same external conveying track; or, a plurality of containers on the same external conveying track are transferred to different layers of temporary storage mechanisms of the robot.
The following detailed description is made on the butt joint of the robot and the container transfer device in the cargo picking scene to realize the transfer of the container:
the container transfer device 12 is configured to transfer a plurality of containers on different layers of temporary storage mechanisms of the robot to a first preset area corresponding to the conveying track in the corresponding layer; the container transfer device 12 is configured to transfer containers at a first predetermined area corresponding to the inner transport rails of different levels to the same outer transport rail. Here, the container transfer device includes a multi-layer internal conveying track. Here, the size of the first predetermined area may be a bottom surface size of the cargo box.
The controller may be configured to control the first container transfer mechanism to lift the plurality of containers from the robot and transfer onto the different levels of container transport mechanisms in response to the first container transfer instructions; controlling each layer of container conveying mechanism to drive the containers to a first preset area corresponding to the layer of container conveying mechanism; respectively controlling a second container transfer mechanism corresponding to each layer of container conveying mechanism, and hooking the containers from the container conveying mechanisms to lifting mechanisms corresponding to the second container transfer mechanisms; and respectively controlling the lifting mechanisms to transfer the containers to the same external conveying track.
Here, the first container transfer instruction may be a container transfer instruction sent to the controller when the robot reaches the container docking station; alternatively, the first sensor assembly can detect that the robot is in the container docking position and send a container transfer instruction to the controller; or, the container transfer instruction may also be issued by the cloud server. The first container transfer instruction may select a suitable sending subject according to a specific application scenario, which is not limited in the embodiment of the present disclosure. Various substitutions and modifications may be made by those skilled in the art without departing from the scope of the present disclosure, and these substitutions and modifications are intended to fall within the scope of the present disclosure.
Based on the control flow of the controller, detailed implementation processes of the mechanisms are described in detail below.
In one embodiment, the first container transfer mechanism 221 may be configured to lift a plurality of containers from the robot 11 and transfer to the container transport mechanism 222. Reference is now made to fig. 4, which is a schematic illustration of the first container transfer mechanism. The first container transfer mechanism 221 includes a plurality of first lift forks 2211, a first drive unit 2212 and a first rail assembly 2213; the first drive unit 2212 is connected to the first rail assembly 2213; a plurality of first jacking prongs 2211 are slidably mounted on the first rail assembly 2213 by support brackets.
It should be noted that the temporary storage mechanism 213 may be a comb mechanism; the first lifting fork 2211 may be a comb mechanism; the container transport mechanism 222 may be a comb mechanism, i.e., the internal transport tracks 2221 (shown in fig. 6) on the container transport mechanism 222 described below are comb mechanisms; the comb mechanism comprises comb teeth; the comb teeth of the temporary storage mechanism 213 and the projection of the comb teeth of the first jacking fork 2211 on the horizontal plane do not overlap; the comb teeth of the first jacking fork 2211 do not overlap with the projections of the comb teeth of the inner conveying track 2221 on the horizontal plane. Exemplarily, inside transfer rail's broach can be a plurality of cylinder, and when first jacking fork was used for shifting the packing box, the broach of first jacking fork can pass the gap between a plurality of cylinder of inside transfer rail, can also pass the gap between the broach of this first jacking fork corresponding layer temporary storage mechanism simultaneously. Specifically, the positional relationship among the temporary storage mechanism, the first lifting fork and the internal conveying track can be seen in fig. 5, which is a structural diagram of a process of transferring a container from the temporary storage mechanism of the robot to the first lifting fork, where a represents that the first lifting fork is at a first initial position, b represents that the first lifting fork leaves from a gap of the internal conveying track and passes through a gap between comb teeth of the temporary storage mechanism, and c represents that the first lifting fork lifts the container.
In specific implementation, the first driving unit 2212 may be used to drive the first guide rail assembly 2213 to rotate according to a preset direction (for example, clockwise or counterclockwise), and the first guide rail assembly 2213 may rotate according to the preset direction to drive the first lifting fork 2211 to move to the position of the butt joint of the cargo box along the vertical direction, at this time, because the comb teeth of the first jacking fork can penetrate through the gaps among the rollers of the internal conveying track and can also penetrate through the gaps among the comb teeth of the temporary storage mechanism on the corresponding layer of the first jacking fork, the container can be lifted up from the temporary storage mechanism, after the robot 11 exits from the container butt joint position, the first driving unit 2212 is used for reversely driving the first guide rail assembly 2213 to rotate in a preset reverse direction, the first guide rail assembly 2213 rotates in the preset reverse direction to drive the first jacking fork 2211 to move to a first initial position in the vertical direction, and the container can be transferred to the container conveying mechanisms 222 on different layers.
In one embodiment, the container transport mechanism 222 may be configured to transfer a container to a corresponding first predetermined area. Here, in order to prevent the processes of moving the containers to the external conveying tracks from conflicting with each other, the first preset areas distributed in a staggered manner are provided, that is, the projections of the first preset areas corresponding to the container conveying mechanisms of different layers on the horizontal plane do not overlap. As can be seen in fig. 6, which is a schematic structural view of the container conveying mechanism, wherein the container conveying mechanism 222 includes an internal conveying track 2221, and the container transferring device 12 further includes at least one limit block 227 and a sensor 228 corresponding to each second container transferring mechanism (the limit block 227-1 corresponds to the sensor 228-1, and the limit block 227-2 corresponds to the sensor 228-2); at least one limiting block may be correspondingly disposed on each layer internal conveying track 2221. Specifically, the inner conveying track is a comb mechanism; the comb mechanism includes comb teeth. Illustratively, the comb teeth of the inner conveying track can be a plurality of rollers, and the limiting blocks can be arranged between the comb teeth gaps of the inner conveying track, such as the gaps of the plurality of rollers shown in fig. 6.
Here, the length of the inner conveying track is adjustable. Specifically, according to a specific application scenario, in order to set a plurality of layers of internal conveying tracks and enable projections of first preset areas on the internal conveying tracks of different layers on a horizontal plane not to overlap, the length of the internal conveying tracks can be adjusted.
The stop block 227 may be configured to define the container at a first predetermined area on the internal conveying track corresponding to the stop block; the projections of the first preset areas corresponding to the limiting blocks on the container conveying mechanisms on different layers on the horizontal plane are not overlapped. Here, the height of the second initial position of the limiting block is lower than the height of the surface, used for placing the container, of the internal conveying track of the corresponding layer, so that the second initial position of the limiting block is set, when the limiting block is located at the second initial position, the container is not influenced to move on the internal conveying track of the corresponding layer of the limiting block, when the limiting block moves upwards and leaves the second initial position, the container can be limited to be located in a first preset area, and the container is waited for subsequent transfer.
The first preset area can limit the position of the container for the limit block, and projections of the first preset areas corresponding to the limit blocks on the container conveying mechanisms on different layers on the horizontal plane are not overlapped, so that the first preset areas can be distributed on the conveying tracks in different layers in a staggered manner, and particularly, refer to fig. 6.
The sensor 228 is configured to detect whether the container has reached a first predetermined area. Here, the sensor 228 may be fixedly mounted to the container conveying mechanism 222 corresponding to the stop block 227. Thereafter, the stop block 227 is configured to be raised to a predetermined height after the sensor detects that the container has reached the first predetermined area, so as to define the container on the internal conveying track at the first predetermined area corresponding to the stop block.
When the container conveying device is specifically implemented, the driving unit of the inner conveying track can be utilized to drive the rollers to rotate, the containers placed on the surface of the inner conveying track are transferred along the conveying direction, at the moment, after the sensor detects that the containers reach a first preset area, the container can be lifted to a preset height by utilizing the limiting block, and the containers on the inner conveying track of the container are limited at the first preset area corresponding to the limiting block.
In one embodiment, the second container transfer mechanism 223 may be configured to hook a container from the corresponding level of container transport mechanisms to the corresponding lift mechanism. Reference is now made to fig. 7, which is a schematic illustration of the second container transfer mechanism. The second container transfer mechanism 223 includes a first tie bar mechanism 2231, a first pusher 2232, and a first tie bar drive unit 2233; one end of the second container transfer mechanism 223 is fixedly assembled on the corresponding lifting mechanism 224, and the other end is fixedly assembled on the container conveying mechanism 222 on the upper layer of the corresponding container conveying mechanism 222; a first toggle block 2232 is installed at one end of the first link mechanism 2231; a first drawbar drive unit 2233 is installed at the other end of the first drawbar mechanism 2231.
The first link driving unit 2233 is configured to drive the first link mechanism to extend and retract.

Here, the first tie rod mechanism 2231 includes a first tie rod 2231-1 and a belt 2231-2, and in practical implementation, the first tie rod driving unit may be used to drive the belt to drive the first tie rod to retract, and the retraction of the first tie rod may drive the first shifting block to hook the container onto the corresponding lifting mechanism, and when the container is already on the lifting mechanism, the first tie rod driving unit may be used to drive the belt to drive the first tie rod to extend out, return to the initial position, and wait for the transfer of the next container.
In one embodiment, the lift mechanism 224 is configured to transfer multiple containers onto the same external transport track. Reference can be made to fig. 8, which is a schematic structural diagram of the lifting mechanism. The lifting mechanism 224 includes a second driving unit 2241, a second guide rail assembly 2242, and a second lifting fork 2243; the second driving unit 2241 is connected with the second guide rail group 2242; second lift-up fork 2243 is slidably mounted on second guide rail assembly 2242. Second lift-up fork 2243 may be a comb mechanism, which includes comb teeth. The comb teeth of the second jacking fork are not overlapped with the projections of the comb teeth of the external conveying track on the horizontal plane. For example, the comb teeth of the external conveying rail may be a plurality of rollers, and when the second lifting fork is used for transferring a container, the comb teeth of the second lifting fork may penetrate through a gap between the plurality of rollers of the external conveying rail.
The second driving unit 2241 is configured to drive the second rail assembly to rotate.
The second guide rail assembly 2242 is configured to drive the second jacking fork to move in the vertical direction under the driving of the second driving unit, so as to transfer the container on the lifting mechanism to the external conveying rail.
When the container is specifically implemented, the container is received at the second jacking fork of the lifting mechanism, then the second driving unit can be utilized to drive the second guide rail assembly, the second guide rail assembly drives the second jacking fork to move to the position of the external conveying track along the vertical direction, at the moment, because the comb teeth of the second jacking fork can penetrate through the gaps among a plurality of rollers of the external conveying track, the container temporarily existing on the second jacking fork can be placed on the external conveying track, after the container is transferred by the external conveying track, the second driving unit is utilized to drive the second guide rail assembly, the second jacking fork is driven to move back to the initial position of the second jacking fork along the vertical direction, and the next container is waited for transferring.
In one possible embodiment, the container transfer device may further comprise a third container transfer mechanism. Specifically, the remaining containers of the robot except the container on the bottom temporary storage mechanism can be transferred by using at least one first container transfer mechanism, a plurality of layers of container conveying mechanisms, a second container transfer mechanism corresponding to each layer of container conveying mechanism and a lifting mechanism corresponding to each second container transfer mechanism in the container transfer device. And aiming at the containers on the temporary storage mechanism at the bottommost layer of the robot, the containers can be transferred by utilizing a third container transfer mechanism. Here, the container on the temporary storage mechanism at the bottommost layer of the robot is directly transferred to the external conveying track by the third container transfer mechanism, so that the first container transfer mechanism, the container conveying mechanism, the second container transfer mechanism and the lifting mechanism corresponding to the bottommost layer of the robot are not needed, and certain structural material cost can be saved.
The first container transfer mechanism is configured to transfer the other containers except the container on the bottom temporary storage mechanism of the robot to the container conveying mechanism of the corresponding layer; the container conveying mechanism is configured to convey the container to a first preset area corresponding to the container conveying mechanism; the projections of first preset areas corresponding to the container conveying mechanisms on different layers on the horizontal plane are not overlapped; the second container transfer mechanism is configured to hook the containers at the corresponding first preset area on the container conveying mechanism of the corresponding layer onto the corresponding lifting mechanism; the projections of different second container transfer mechanisms on the horizontal plane are not overlapped; the lifting mechanism is configured to transfer the containers onto the same external conveying track; the third container transfer mechanism is configured to transfer a container on the robot bottommost buffer mechanism to the external transport track.

In some embodiments, the third container transfer mechanism may be configured to transfer a container on the robot bottommost buffer mechanism to the external transport track. Reference is now made to fig. 9, which is a schematic illustration of a third container transfer mechanism, which includes a jacking mechanism 2261 and a tie bar transfer mechanism 2262.
It should be noted that the jacking mechanism 2261 may be a comb mechanism. The projections of the comb teeth of the temporary storage mechanism 213 and those of the jacking mechanism 2261 on the horizontal plane do not overlap; the comb teeth of the jacking mechanism 2261 do not overlap with the projections of the comb teeth of the outer conveying track 225 on the horizontal plane. Therefore, when the jacking mechanism 2261 is lifted, the container temporarily stored on the lowermost temporary storage mechanism 213 by the robot 11 can be lifted by passing through the outer conveying rail 225 and the temporary storage mechanism 213 through the gap between the comb teeth of the outer conveying rail 225 and the temporary storage mechanism 213. After the tie bar transfer mechanism 2262 transfers the container on the jacking mechanism 2261 to the second predetermined area, the jacking mechanism 2261 is retracted to the third initial position to transfer the container at the second predetermined area to the outer transport track 225. Here, the second preset area may be a position where the jacking mechanism is located right above the outer conveying rail. For example, whether a container exists in the second preset area may be detected by a sensor, and in the case that a container exists in the second preset area, a signal indicating that a container exists in the second preset area is sent to the controller, and the controller may control the jacking mechanism to perform an action of returning to the third initial position according to the signal. Here, the size of the second predetermined area may be a bottom surface size of the cargo box.
In some embodiments, the tie bar transfer mechanism 2262 may be configured to transfer a container on the jacking mechanism to a second predetermined area of the jacking mechanism.
As shown in fig. 9, the lever transferring mechanism 2262 includes a second lever mechanism 2262-1, a second shifting block 2262-2, and a second lever driving unit 2262-3. A second shifting block 2262-2 is arranged at one end of a second pull rod mechanism 2262-1; a second lever drive unit 2262-3 is installed at the other end of the second lever mechanism 2262-1.
The second link driving unit 2262-3 may be configured to drive the second link mechanism to extend and retract.

Here, the specific structure and the operation principle of the tie rod transfer mechanism may refer to the second container transfer mechanism described above, and are not described in detail herein.
In some embodiments, the container transfer apparatus may further comprise a fourth container transfer mechanism, which may be configured to transfer a container from the robotic bottom buffer onto the external transport track.
The fourth container transfer mechanism may include a third tie bar mechanism, a third paddle, a third tie bar drive unit, and a third paddle drive unit. The third shifting block is arranged at one end of the third pull rod mechanism; the third pull rod driving unit is installed at the other end of the third pull rod mechanism.
The third shifting block driving unit can be configured to drive the third shifting block to rotate from the initial horizontal position to the vertical position so as to hook the container.
The third link driving unit may be configured to drive the third link mechanism to extend and contract.
The third pull rod mechanism can be configured to drive the third shifting block to hook the container on the bottom temporary storage mechanism onto the external conveying track under the driving of the third pull rod driving unit.
In a possible embodiment, at least one lifting mechanism may be provided in the container transfer device, and the lifting mechanism may not correspond to the second container transfer mechanism one by one, that is, the lifting mechanism is used to transfer the containers on the multi-layer internal conveying track to the external conveying track. In a specific implementation, the container transfer device may include a lifting mechanism, and at this time, the position where the container conveyed on the conveying rails in different layers is limited may be selected arbitrarily, wherein the position where the container on each conveying rail in different layers is limited is provided with a second container transfer mechanism correspondingly. The lifting mechanism can move in a two-dimensional scene coordinate to acquire containers on the internal conveying tracks of different layers and transfer the containers to the external conveying tracks. Specifically, the first container transfer mechanism is configured to lift a plurality of containers from the robot and transfer the containers to the container conveying mechanism on different layers; the container conveying mechanism is configured to convey the container to a first preset area corresponding to the container conveying mechanism; the second container transfer mechanism is configured to hook the containers at the corresponding first preset area on the container conveying mechanism of the corresponding layer onto the lifting mechanism; the lift mechanism is configured to transfer the containers onto the same external transport track.
