Description

Technical Field

[0001] This application relates to the field of warehousing and logistics technology, and in particular to a warehousing security system. Background Technology

[0002] In the context of Industry 4.0, the rapid development of robotics has brought about tremendous technological changes to the entire logistics industry. Currently, the mainstream robot solutions mainly include two types: shelf-to-person and cargo-to-person. Shelf-to-person refers to robots moving shelves to workstations to complete picking tasks; cargo-to-person refers to robots moving cargo boxes to workstations to complete picking tasks.

[0003] While modern robots have become increasingly intelligent, safety during human-robot interaction cannot be ignored. This is especially true in shelving and picking operations, where operators often need to cooperate extensively with robots to complete the shelving process. During this process, operators may need to approach the robot for operational purposes or accidentally enter the robot's area. If the robot moves rapidly towards the operator at this time, it could potentially collide with them, posing a safety risk.

[0004] Therefore, how to design safety plans for operations such as shelving and picking to ensure both the normal operation of robots and the safety of operators is an urgent problem to be solved. Summary of the Invention

[0005] This application provides a warehouse safety system to address the lack of safety protection for operators interacting with robots during current shelving and picking operations.

[0006] This application provides a warehouse safety system, including a handling robot operating in a robotic area and a workstation located in a manual area, as well as a detection device located at the workstation. The workstation is used to process containers, and the handling robot is responsible for the allocation of containers between the manual area and the robotic area. The detection device includes a first detection unit and a second detection unit, and a control unit electrically connected to the first detection unit and the second detection unit respectively. The first detection unit is used to detect whether the handling robot has reached the docking position of the workstation, and the second detection unit is used to detect whether an object has entered the robotic area from the manual area. The first detection unit and the second detection unit respectively send a first detection signal and a second detection signal to the control unit. The control unit is also electrically connected to the handling robot, and in response to the received first detection signal, the control unit controls the second detection unit to shut down, and in response to the received second detection signal, controls the handling robot to stop moving.

[0007] In one feasible implementation, the workstation includes a base with a working window and a folding baffle disposed at the working window. The folding baffle has an unfolded state for carrying containers transferred between the robot area and the manual area, and a stowed state for picking containers transferred by the handling robot.

[0008] In one feasible implementation, there are two first detection units, and the two first detection units are symmetrically arranged below the working window; the second detection unit includes a transmitter and a receiver, and the transmitter and the receiver are symmetrically arranged on the two inner sidewalls of the working window.

[0009] In one feasible implementation, the warehouse security system further includes a display disposed above the working window, the display being electrically connected to the control unit for displaying the operating status of the warehouse security system.

[0010] In one feasible implementation, the detection device further includes an indicator light and an alarm, which are electrically connected to the control unit respectively. The indicator light is used to issue an indication signal to indicate the operating status of the workstation based on the first detection signal and the second detection signal received by the control unit, and the alarm is used to issue an alarm signal based on the second detection signal received by the control unit.

[0011] In one feasible implementation, the warehouse safety system further includes an emergency stop and reset control box located at the workstation. The emergency stop and reset control box is electrically connected to the handling robot and the alarm, respectively. The emergency stop and reset control box includes an emergency stop switch and a reset button. The emergency stop switch responds to the alarm signal emitted by the alarm to control the handling robot to stop moving, and the reset button responds to a pressing action to control the handling robot to resume moving.

[0012] In one feasible implementation, the transport robot includes a normal driving mode and a low-speed driving mode, and the control unit controls the transport robot to switch from the normal driving mode to the low-speed driving mode in response to the distance between the transport robot and the parking position.

[0013] In one feasible implementation, the warehouse security system further includes a fence connected to the base, and the fence is located between the robot area and the manual area to achieve separation between the robot area and the manual area.

[0014] In one feasible implementation, a safety gap is provided between the robotic area and the manual area.

[0015] In one feasible implementation, both the first detection unit and the second detection unit are one of an infrared sensor, a photoelectric sensor, or an ultrasonic sensor.

[0016] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows:

[0017] This application provides a warehouse safety system that uses detection devices to monitor containers in the robotic area and operators in the manual area in real time. This prevents the handling robot from directly impacting the operator if they accidentally enter the robotic area due to improper operation, thus ensuring the operator's safety and the stable operation of the warehouse system. Specifically, the detection device includes a first detection unit and a second detection unit, as well as a control unit electrically connected to both. When the control unit receives a first detection signal from the first detection unit, it indicates that the handling robot has reached its stopping position, and the operator can interact with it. At this time, to ensure the smooth operation of the operator, the control unit shuts down the second detection unit to prevent false detections. Furthermore, when the control unit receives a second detection signal, it indicates that an object (such as the operator's hand or foot) has entered the robotic area from the manual area, suggesting a possible operator error. In this case, to prevent the handling robot in the robotic area from directly impacting the operator, the control unit stops the handling robot, greatly reducing the risk of injury to the operator.

[0018] The warehouse safety system provided in this application greatly improves the overall safety and reliability of the system through the linkage and cooperation of the first detection unit and the second detection unit set in the detection device with the handling robot, workstation, etc., which is conducive to the stable operation of the shelving and picking process. It can not only ensure the normal operation of the handling robot, but also ensure the safety of the operators. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0030] Reference Figures 1-5 As shown, this application provides a warehouse safety system, including a handling robot 110 operating in a robot area 100 and a workstation 210 set in a manual area 200, as well as a detection device (not marked in the figure) set in the workstation 210. The workstation 210 is used to process containers, and the handling robot 110 is responsible for the allocation of containers between the manual area 200 and the robot area 100.

[0031] It should be noted that, in the embodiments of this application, the robot area 100 refers to the area where the robot operates, which may include shelves, cabinets, etc., such as the inventory container area, the container waiting to be put on the shelf area, the buffer area, etc.; the manual area 200 refers to the area where the operator works, which may include workstations 210, picking stations, operating tables, etc., such as the order picking area, the container putting area, etc.

[0032] Furthermore, the containers in this application embodiment can include general-purpose containers and special-purpose containers. General-purpose containers refer to containers that can store any goods, such as storage boxes or organizers. Special-purpose containers refer to containers specifically designed for storing a particular type or category of goods, such as shoe boxes, fresh produce boxes, or buckets. In terms of material, the present invention includes cardboard boxes, glass bottles, plastic boxes, metal boxes, and leather cases.

[0033] In addition, in practical applications, the handling robot 110 varies depending on the content being handled. If it is handling containers containing goods, the handling robot 110 can be a container handling robot 110; if it is handling mobile shelves containing containers, the handling robot 110 can be a shelf handling robot 110; if it is handling stacked goods, the handling robot 110 can be a forklift, etc.; if it is handling cage carts containing goods, the handling robot 110 can be a traction robot or a lifting robot, etc.

[0034] Furthermore, the detection device includes a first detection unit 211 and a second detection unit 212, and a control unit 213 electrically connected to both the first detection unit 211 and the second detection unit 212. The first detection unit 211 detects whether the transport robot 110 has reached the docking position of the workstation 210, and the second detection unit 212 detects whether an object has entered the robot area 100 from the manual area 200. The first and second detection units 211 and 212 respectively send a first detection signal and a second detection signal to the control unit 213. The control unit 213 is also electrically connected to the transport robot 110, and in response to the received first detection signal, the control unit 213 controls the second detection unit 212 to shut down, and in response to the received second detection signal, controls the transport robot 110 to stop moving.

[0035] It should be noted that the control unit 213 in this application embodiment may be a control box set in the workstation 210, or a main control cabinet set independently of the workstation 210, or a remote server that communicates wirelessly with the first detection unit 211, the second detection unit 212 and the handling robot 110 respectively. This application does not limit the type of control unit 213.

[0036] In some embodiments, both the first detection unit 211 and the second detection unit 212 can be one of an infrared sensor, a photoelectric sensor, or an ultrasonic sensor. Furthermore, the types of the first detection unit 211 and the second detection unit 212 can be the same or different; this application embodiment does not limit this.

[0037] In the specific shelving and picking operations, the transport robot 110 located in the container waiting area (robot area 100) can transport containers from the shelves to the workstation 210. When the transport robot 110 reaches its docking position, the first detection unit 211 located below the workstation 210 detects the transport robot 110 and sends the generated first detection signal to the control unit 213. At this time, the operator at the workstation 210 needs to operate on the containers on the transport robot 110 (such as picking, labeling, inspection, etc.). Since the operator needs to interact with the transport robot 110 during the operation, the operator's hands or head may cross the manual area 200 of the workstation 210 and enter the robot area 100 where the transport robot 110 is located. In order to avoid false detection by the detection device during the operation, the control unit 213 in this embodiment can control the second detection unit 212 to shut down according to the received first detection signal. That is, when the transport robot 110 reaches its docking position and the operator needs to perform relevant operations, the second detection unit 212 stops detection.

[0038] It is understandable that, in order to ensure the accuracy of the detection device and to minimize the risk of operators accidentally entering the robot area 100, thereby ensuring the personal safety of the operators, the second detection unit 212 in this embodiment should remain on except when the first detection unit 211 detects that the handling robot 110 has reached the docking position. Otherwise, it should remain on whenever any workstation 210 is in normal working condition.

[0039] When the second detection unit 212 generates the second detection signal, it indicates that an object (such as the operator's hand or foot) has entered the robot area 100 from the manual area 200. This means that the operator may have made a mistake. In order to prevent the handling robot 110 in the robot area 100 from rushing directly towards the operator, the control unit 213 can control the handling robot 110 to stop moving in time according to the received second detection signal. This greatly reduces the risk of injury to the operator and helps to ensure the personal safety of the operator and the stable operation of the warehousing system.

[0040] The warehouse safety system provided in this application, through the linkage and cooperation of the first detection unit 211 and the second detection unit 212 set in the detection device with the handling robot 110, workstation 210, etc., greatly improves the overall safety and reliability of the system, which is conducive to the stable operation of the shelving and picking process. It can not only ensure the normal operation of the handling robot 110, but also ensure the safety of the operators.

[0041] Figure 6 This is a schematic diagram of another workstation provided in an embodiment of this application.

[0042] In one feasible implementation, refer to Figure 2 and Figure 6 As shown, the workstation 210 may include a base 220 with a work window 221 and a folding baffle 222 disposed at the work window 221. The folding baffle 222 has an unfolded state for carrying containers transferred between the robot area 100 and the manual area 200, and a stored state for picking containers transferred by the handling robot 110.

[0043] This configuration serves two purposes. First, when the folding baffle 222 is in its retracted state (i.e., the folding baffle 222 is upright), it effectively separates the manual area 200 from the robot area 100, preventing operators from easily crossing the manual area 200. Furthermore, at this time, operators can perform operations such as picking containers on the handling robot 110. Second, when the folding baffle 222 is in its unfolded state (i.e., the folding baffle 222 is flattened), it can support containers transferred between the manual area 200 and the robot area 100, thus facilitating related operations by operators.

[0044] Furthermore, the edge of the folding baffle 222 can be provided with a pivot, and the two side walls of the working window 221 are provided with shaft holes. The folding baffle 222 can rotate relative to the base 220 through the cooperation between the pivot and the shaft holes, thereby realizing the switching between the folding baffle 222 in the stored state and the unfolded state. Preferably, the workstation 210 may also include a pull rod (not marked in the figure). One end of the pull rod is fixed to both sides of the working window 221, and the other end is connected to the folding baffle 222. The pull rod enables the folding baffle 222 to remain stable in the unfolded state, and the folding baffle 222 in the unfolded state has a certain strength under the pulling force of the pull rod, thereby enabling the folding baffle 222 to have a carrying function. Operators can place frequently used tools such as scissors and tape in the folding baffle 222, and can also temporarily place containers on the handling robot 110 in the folding baffle 222.

[0045] Regarding the connection method between the folding baffle 222 and the base 220, in addition to the structure described above, the folding baffle 222 and the base 220 can also be connected by hinges, pins, etc. Furthermore, when switching between the unfolded and retracted states, the folding baffle 222 can rotate relative to the base 220, or it can extend or retract relative to the base 220. This application embodiment does not limit the structure of the folding baffle 222 or the connection method with the base 220.

[0046] It should be noted that, in order to ensure the normal operation of the operator while preventing the handling robot 110 from directly rushing towards the operator or the operator from entering the robot area 100, a working window 221 can be opened on the workstation 210 to facilitate the passage of containers. In this embodiment, the size of the working window 221 is not limited; those skilled in the art can make a reasonable selection based on the specific size of the container or the actual product design requirements. For example, when designing the ground clearance of the lower surface of the working window 221, the ease with which the operator can move the container to the folding baffle 222 can be considered; when designing the ground clearance of the upper surface of the working window 221, the height of the operator and the minimum height required to prevent the operator from climbing over the working window 221 can be considered.

[0047] In some embodiments, continue to refer to Figure 3 and Figure 4 As shown, there can be two first detection units 211, and the two first detection units 211 are symmetrically arranged below the working window 221. The second detection unit 212 may include a transmitter and a receiver, and the transmitter and receiver are symmetrically arranged on the two inner sidewalls of the working window 221.

[0048] Setting two first detection units 211 can further improve the accuracy of the first detection unit 211. For example, although the transport robot 110 has reached the docking position, it is not in the center of the docking position, but slightly off-center, located on the right side. In this case, if there is only one first detection unit 211 located below the work window 221 in the workstation 210, it is very likely that the transport robot 110, which has reached the docking position, will not be detected, resulting in missed detection. However, with two first detection units 211 symmetrically arranged below the work window 221, through reasonable positioning design, one first detection unit 211 is closer to the left side of the docking position, and the other first detection unit 211 is closer to the right side of the docking position. In this way, even if the transport robot 110 deviates from the docking position, it can still be detected, thereby improving the detection accuracy of the first detection unit 211. It is understood that the embodiments of this application do not limit the specific number of first detection units 211. In addition to two, it can also be set to three, four, etc.

[0049] Furthermore, regarding the working principle of the second detection unit 212, this application will use an infrared sensor as an example for explanation. The transmitting end of the second detection unit 212 emits infrared light, and the receiving end receives infrared light. Since the transmitting and receiving ends of the second detection unit 212 are positioned correspondingly on the two inner sidewalls of the working window 221, when no object passes through the working window 221, the receiving end can receive the infrared light emitted by the transmitting end. When an object passes through the working window 221, the infrared light emitted by the transmitting end is blocked by the object, and the receiving end cannot receive the corresponding infrared light, thus indicating that an object is passing through the working window 221. At this time, the second detection unit 212 generates a second detection signal and sends it to the control unit 213. The control unit 213 then takes the next action, controlling the handling robot 110 to stop moving.

[0050] In one feasible implementation, refer to Figure 2 and Figure 4 As shown, the warehouse security system may also include a display 230 disposed above the work window 221. The display 230 is electrically connected to the control unit 213 to display the operating status of the warehouse security system.

[0051] The display 230 allows operators to monitor the operation of the workstation 210. It also provides operators with various auxiliary information, such as the type and quantity of items being picked, or prompts them to perform corresponding operations.

[0052] In some embodiments, continue to refer to Figure 2 and Figure 4 As shown, the detection device may also include an indicator light 240 and an alarm (not shown) that are electrically connected to the control unit 213 respectively. The indicator light 240 is used to issue an indication signal to indicate the operating status of the workstation 210 according to the first detection signal and the second detection signal received by the control unit 213. The alarm is used to issue an alarm signal according to the second detection signal received by the control unit 213.

[0053] The operating status of workstation 210 can be determined based on the first and second detection signals received by control unit 213. For example, when control unit 213 receives neither the second nor the first detection signal, it indicates that workstation 210 is in an idle state; when control unit 213 receives the first detection signal but not the second detection signal, it indicates that workstation 210 is in a working state; when control unit 213 receives the second detection signal, it means that an object has passed through the working window 221, indicating that workstation 210 is in an abnormal state. Correspondingly, indicator light 240 can emit different types of light signals depending on the operating status of workstation 210. For example, indicator light 240 emits red light to indicate that workstation 210 is in an abnormal state; indicator light 240 emits green light to indicate that workstation 210 is in an idle state; indicator light 240 emits yellow light to indicate that workstation 210 is in a working state.

[0054] Furthermore, when the workstation 210 is in an abnormal state, the alarm connected to the control unit 213 can promptly issue an alarm signal, which may be a buzzer, voice broadcast, music, etc.

[0055] In one feasible implementation, refer to Figure 2 As shown, the warehouse safety system also includes an emergency stop / reset control box 250 located at workstation 210. The emergency stop / reset control box 250 is electrically connected to the handling robot 110 and the alarm. The emergency stop / reset control box 250 includes an emergency stop switch (not marked in the figure) and a reset button (not marked in the figure). The emergency stop switch, in response to an alarm signal from the alarm, controls the handling robot 110 to stop moving. The reset button, in response to being pressed, controls the handling robot 110 to resume moving. The installation location of the emergency stop / reset control box 250 on workstation 210 should be easily accessible to the operator.

[0056] This embodiment of the application further enhances the security of the warehouse safety system by incorporating an emergency stop reset control box 250. In the event of an emergency, or if the detection device malfunctions and falsely detects an error, the operator can press the emergency stop switch to stop the handling robot 110. The emergency stop switch can also actively control the handling robot 110 to stop in response to an alarm signal. When the fault or emergency is resolved, the operator can press the reset button to resume the movement of the handling robot 110.

[0057] In one feasible implementation, the transport robot 110 includes a normal driving mode and a low-speed driving mode, and the control unit 213 controls the transport robot 110 to switch from the normal driving mode to the low-speed driving mode in response to the distance between the transport robot 110 and the parking position.

[0058] To further enhance the safety of the warehouse security system, this application sets the driving mode of the handling robot 110 to a normal driving mode and a low-speed driving mode. Specifically, when the handling robot 110 is working normally in the robot area 100, it can move in the normal driving mode at a speed of 20-25 m / s. When the handling robot 110 reaches the preset safety range of the workstation 210's stopping position, it switches from the normal driving mode to the low-speed driving mode at a speed of 5-10 m / s.

[0059] Furthermore, the safe zone of the docking position refers to the distance extending outwards from the docking position as the center. For example, the area within 2m or 3m around the docking position is considered the safe zone. By setting the safe zone, the handling robot 110 can move at a reduced speed when it is about to enter, arrives at, or leaves the docking position, thereby avoiding potential injury to the operator caused by the handling robot 110 moving too fast.

[0060] In some embodiments, refer to Figure 6 As shown, the workstation 210 may also include a kick-proof net 260 disposed below the base 220. The kick-proof net 260 can, on the one hand, separate the manual area 200 and the robot area 100 to a certain extent, and on the other hand, can prevent the operator from kicking the handling robot 110 due to operational errors, thereby helping to ensure the safety of the operator and the handling robot 110.

[0061] In one feasible implementation, the warehouse security system also includes a fence (not shown) connected to the base 220, and the fence is located between the robot area 100 and the manual area 200 to separate the robot area 100 from the manual area 200.

[0062] The fence can be used to enclose the manual area 200 into a closed area, or to enclose the robot area 100 into a closed area, or to enclose the robot area 100 and the manual area 200 into separate closed areas. This application does not limit this.

[0063] Optionally, in this embodiment of the application, conspicuous identification marks may be set on the ground corresponding to the robot area 100 and / or the manual area 200 to remind operators not to easily enter the robot area 100.

[0064] In another feasible implementation, a safety gap can be maintained between the robot area 100 and the manual area 200. Since the handling robot 110 performs actions such as starting, stopping, lifting, and rotating during operation, a certain safety distance should be maintained between the interaction positions of the manual area 200 where the operator is located and the robot area 100 where the handling robot 110 is located to ensure the safety of the operator.

[0065] To facilitate understanding, the working process of the warehouse security system provided in this application embodiment will be described below with a specific example:

[0066] In the specific shelving or picking operation, the operator is located at workstation 210. Workstation 210 starts running, and the first detection unit 211 and the second detection unit 212 are also turned on. Since the control unit 213 has not yet received the first detection signal and the second detection signal, the indicator light 240 indicates that the current workstation 210 is in an idle state.

[0067] When the handling robot 110 moves a container from the shelving area to its docking position, the first detection unit 211 detects the arrival of the handling robot 110 and sends a first detection signal to the control unit 213. Based on the received first detection signal, the control unit 213 controls the second detection unit 212 to shut down, and the indicator light 240 indicates that the workstation 210 is currently in operation. At this time, the operator can perform shelving or picking operations on the containers through the work window 221.

[0068] When the handling robot 110 leaves its docking position, the operator ceases normal operations, and the control unit 213 receives neither the first nor the second detection signal. The workstation 210 then transitions from an active state to an idle state, and the second detection unit 212 reactivates. At this point, if the operator makes a mistake, such as placing their hand through the work window 221, the second detection unit 212 will detect an object crossing the manual area 200 into the robot area 100, generating a second detection signal and sending it to the control unit 213. Based on the received second detection signal, the control unit 213 will control the handling robot 110 to stop moving. The indicator light 240 will show that the workstation 210 is in an abnormal state, and the alarm will simultaneously sound to alert the operator of the current danger.

[0069] It is readily understood that, based on the several embodiments provided in this application, those skilled in the art can combine, split, or reorganize the embodiments of this application to obtain other embodiments, none of which exceed the protection scope of this application.

It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
