Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics technology, specifically to a material transfer device and a warehousing system including the material transfer device. Background Technology

[0002] An automated warehousing system includes shelves and multiple handling robots, where shelves are used to store materials and handling robots are used to move materials out of and into the warehouse.

[0003] It should be noted that when materials are being taken out of or into the warehouse, the handling robots need to transfer the materials to a material transfer station, where operators will pick up and place the materials. Typically, there are many handling robots, and they travel at high speeds, resulting in frequent handovers between personnel and robots. During these handover operations at the warehouse workstations, operators' hands are very susceptible to injury from collisions or crushing.

[0004] Ensuring the personal safety of operators at material transfer stations is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0044] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0045] like Figure 1 As shown, this embodiment of the present invention provides a material transfer device, which includes a material transfer platform 100. The material transfer platform 100 has a bearing surface for carrying materials, and the bearing surface of the material transfer platform 100 is divided into an inbound area 110 and an outbound area 120 adjacent to the inbound area 110. The material transfer device also includes a first detection component and a second detection component.

[0046] The first detection component and the second detection component are used to detect the inbound area and the outbound area from both sides of the material transfer station 100, respectively. The first component is used to generate a first detection signal when an object is detected, and the second detection component is used to generate a second detection signal when an object is detected.

[0047] It should be noted that the "object" here is not limited to the bin or material; a corresponding detection signal is generated whenever an object is detected. Furthermore, both the first and second detection components are electrically connected to the control module, which uses the time difference between the first and second detection signals to determine whether the material has been properly received and discharged.

[0048] For ease of description, the direction of material movement when entering and leaving the material transfer platform is called the length direction of the material transfer platform, and the direction perpendicular to the length direction is called the width direction of the material transfer platform. Figure 1 The vertical direction in the text represents the length of the material transfer platform. Figure 1 The left and right directions in the text represent the width of the material transfer platform.

[0049] Both the first and second detection components are used to detect the materials in the receiving area 110 and the outgoing area 120. It is easy to understand that the materials to be transferred have a certain length and width, and during normal material inflow and outflow, both the first and second detection components located on either side of the material transfer platform can detect the materials. Furthermore, the time difference between the first detection signal generated by the first detection component and the second detection signal generated by the second detection component is fixed.

[0050] For example, if the first detection component and the second detection component are arranged symmetrically on the left and right sides of the material transfer platform and about the center line of the material transfer platform, then if the material passes through the material transfer platform normally and no foreign objects (e.g., palms, arms) intrude, the time difference between the first detection signal and the second detection signal is 0.

[0051] If the material tilts significantly when passing through the material transfer station, the first and second detection components will not detect the material simultaneously; that is, the time difference between the first and second detection signals will not be zero. Consequently, the control module electrically connected to the first and second detection components will not generate a normal outbound or inbound signal. If an operator's hand passes from one side of the material platform through the outbound area into the inbound area, the detection component on that side will generate a detection signal, while the detection component on the other side will not.

[0052] Even with asymmetrical arrangements of the first and second detection components, if material transfer is normal and no foreign objects (e.g., hands, arms) intrude, the time difference between the first and second detection signals is fixed. For example, under normal warehousing conditions, the time difference between the first and second detection signals is Δt1; under normal outbound conditions, the time difference is Δt2. If the time difference between the first and second detection signals is not Δt1 during warehousing, an warehousing anomaly is identified; if the time difference is not Δt2 during outbound conditions, an outbound anomaly is identified.

[0053] In summary, there are two possible reasons for abnormal inbound / outbound operations: one is abnormal intrusion (e.g., a person's arm, palm, or fingers) obstructing the first or second detection component; the other is that the material has tilted. It should be noted that if the material tilts excessively, it may fall from the material transfer table 100, causing damage to the material and potentially injuring the operator.

[0054] By setting up a first detection component and a second detection component that can detect on both sides of the material transfer station 100 respectively, and calculating the time difference between the first detection signal generated by the first detection component and the second detection signal generated by the second detection component, it is possible to determine whether the material is transferred normally and whether an abnormal intrusion has occurred. This ensures both the safety and integrity of the material and the personal safety of the operators.

[0055] Once the control device determines that the material has tilted or that there has been an abnormal intrusion based on the time difference between the first and second detection signals, it can perform subsequent operations.

[0056] In this embodiment of the invention, the specific type of "subsequent operation" is not specifically limited. For example, a "subsequent operation" could be a control signal prompting device issuing a prompt message to remind the operator to stop pushing the material. Another example is a control auxiliary device adjusting the material to a set posture.

[0057] In this embodiment of the utility model, there is no special limitation on the specific types of the first detection component and the second detection component, as long as they can detect the inbound area 110 and the outbound area 120 from both sides of the material transfer table 100.

[0058] As an optional implementation, both the first detection component and the second detection component can be proximity switches. The first detection component generates a first detection signal when it detects an object, and the second detection component generates a second detection signal when it detects an object.

[0059] As another optional implementation, the first detection component may include a first detection signal transmitter 211 and a first detection signal receiver 212, and correspondingly, the second detection component may include a second detection signal transmitter 221 and a second detection signal receiver 222.

[0060] One of the first detection signal transmitter 211 and the first detection signal receiver 212 is located in the inbound area 110, and the other of the first detection signal transmitter 211 and the first detection signal receiver 212 is located in the outbound area 120. The signal transmitting surface of the first detection signal transmitter 211 faces the signal receiving surface of the first detection signal receiver 212.

[0061] One of the second detection signal transmitter 221 and the second detection signal receiver 222 is disposed in the inbound area 110, and the other of the second detection signal transmitter 221 and the second detection signal receiver 222 is disposed in the outbound area 120, with the signal transmitting surface of the second detection signal transmitter 221 facing the signal receiving surface of the second detection signal receiver 222.

[0062] The first detection signal transmitter 211 and the second detection signal transmitter 221 are flush with each other and located on both sides of the material transfer platform 100; the first detection signal receiver 212 and the second detection signal receiver 222 are flush with each other and located on both sides of the material transfer platform 100.

[0063] In this embodiment, the first detection signal receiver 212 generates a first response signal when it does not receive a detection signal transmitted by the first detection signal transmitter 211, and generates a first detection signal when it receives a detection signal transmitted by the first detection signal transmitter 211; the second detection signal receiver 222 generates a second response signal when it does not receive a detection signal transmitted by the second detection signal transmitter 221, and generates a second detection signal when it receives a detection signal transmitted by the second detection signal transmitter 221.

[0064] In this embodiment of the invention, the materials are mostly rectangular box-shaped structures with symmetrical structures. When materials are transferred from the material transfer platform 100, the signal transmission channels between the first detection signal transmitter 211 and the first detection signal receiver 212, as well as the signal transmission channels between the second detection signal transmitter 221 and the second detection signal receiver 222, are blocked by the materials. Accordingly, the signal generated by the first detection signal receiver 212 at this time is the first detection signal, and the signal generated by the second detection signal receiver 222 at this time is the second detection signal.

[0065] In the above implementation, the transmission direction of the signal emitted by the first detection signal transmitter 211 is intersecting with the transmission direction of the signal emitted by the second detection signal transmitter 221. Regardless of whether the material is tilted, both the first detection component and the second detection component can quickly detect the material.

[0066] As an optional implementation, the first detection signal transmitter 211 and the second detection signal transmitter 221 are flush with each other and located on opposite sides of the material transfer platform 100, and the first detection signal receiver 212 and the second detection signal receiver 222 are flush with each other and located on opposite sides of the material transfer platform 100. In this case, if the time difference between the first and second detection signals is 0 (or within a relatively small range), it can be determined that the material transfer is normal and there is no abnormal intrusion. If the time difference between the first and second detection signals is not 0 (or exceeds a certain range), an abnormality is determined, and a corresponding prompt signal is generated.

[0067] In this embodiment of the invention, the positions of the first detection signal transmitter and the second detection signal transmitter are not specifically limited. As an optional implementation, both the first detection signal transmitter 211 and the second detection signal transmitter 221 are located in the inbound area 110. Of course, both the first detection signal transmitter 211 and the second detection signal transmitter 221 can also be located in the outbound area 120.

[0068] As an optional implementation, the first detection signal transmitter 211 is an optical signal transmitter, and the first detection signal receiver 212 is an optical signal receiver; the second detection signal transmitter 221 is an optical signal transmitter, and the second detection signal receiver 222 is an optical signal receiver.

[0069] To more accurately determine whether the operator's hand has entered the storage area and to improve the safety of the material handover process, the material handover device may also include a third detection component. This third detection component is used to generate an abnormal intrusion signal when an object whose size meets the set conditions is detected to enter the storage area 110 from the exit area 120 and the time interval between the first detection signal and the second detection signal does not meet the set conditions.

[0070] It should be noted that the above "setting conditions" include two cases: the first case is that the time interval between the first detection signal and the second detection signal is 0; the second case is that when the material enters the warehouse, the time difference between the first detection signal and the second detection signal is Δt1, and when the material leaves the warehouse, the time difference between the first detection signal and the second detection signal is Δt2.

[0071] Here, "size meets the set conditions" can mean at least one of the following: size similar to the size of a human hand, size similar to the size of a human finger, and size similar to the size of a human arm. It should be noted that the third detection component sends an abnormal intrusion signal to the control device, which then performs subsequent operations based on this signal.

[0072] In this embodiment of the invention, the specific structure of the third detection component is not specifically limited. As an optional implementation, the third detection component includes a plurality of third detection signal transmitters 310 arranged at intervals along the height direction, and a plurality of third detection signal receivers 320 arranged at intervals along the height direction. Each of the plurality of third detection signal transmitters 310 and the plurality of third detection signal receivers 320 corresponds one-to-one, with the signal transmitting surface of the third detection signal transmitter 310 facing the signal receiving surface of the corresponding third detection signal receiver 320.

[0073] The third detection signal transmitter 310 and the third detection signal receiver 320 are located on both sides of the material transfer platform, respectively.

[0074] Since the size of a human hand is relatively small, the third detection component mentioned above can be a planar detection sensor (e.g., a grating) with a certain resolution that can detect small objects, thereby avoiding the missed detection when a human hand enters the inbound area 110 from the outbound area 120.

[0075] For ease of installation, optionally, the corresponding third detection signal transmitters 310 and third detection signal receivers 320 are of the same height, and the interval between two adjacent third detection signal transmitters does not exceed a set distance. In this embodiment of the invention, the distance between two adjacent third detection signal transmitters can be determined based on the size of a human hand.

[0076] As described above, the third detection component can be a planar detection sensor. Correspondingly, the third detection component may also include a mounting bracket, which is a gate-like structure, with the third detection signal transmitter 310 and the third detection signal receiver 320 mounted on two columns of the gate-like structure.

[0077] To improve safety, the third detection component may optionally be located at the boundary between the inbound area 110 and the outbound area 120.

[0078] To more conveniently determine the entry and exit status of materials, the material transfer device may optionally include a fourth detection component, which is used to detect the entry area 110 and generate an exit signal when it detects that materials enter the entry area 110 from the end of the material transfer platform away from the exit area 120.

[0079] It should be noted that the fourth detection component is electrically connected to the control device. After the outbound signal is sent to the control device, the control device can send a shielding signal to the third detection component to control the third detection component to stop detection, thereby avoiding affecting the operator's normal inbound and outbound operations.

[0080] Furthermore, such as Figure 2 As shown, the fourth detection component includes a fourth detection signal transmitter 410 and a fourth detection signal receiver 420. Both the fourth detection signal transmitter 410 and the fourth detection signal receiver 420 are located on the edge of the material transfer platform 100 away from the outbound area. The fourth detection signal transmitter 410 and the fourth detection signal receiver 420 are located on both sides of the material transfer platform, with the signal transmitting surface of the fourth detection signal transmitter 410 and the signal receiving surface of the fourth detection signal receiver 420 facing each other.

[0081] As an optional implementation, the fourth detection signal transmitter 410 is an optical signal transmitter, and the fourth detection signal receiver 420 is an optical signal receiver.

[0082] The so-called "outbound signal" is the fourth response signal generated when the fourth detection signal receiver does not receive the signal emitted by the fourth detection signal transmitter. After the material is pushed to the edge of the material transfer platform 100, the signal between the fourth detection signal transmitter 410 and the fourth detection signal receiver 420 is blocked. Since the fourth detection signal transmitter 410 and the fourth detection signal receiver 420 are located at the edge of the material transfer platform 100, the generation of the outbound signal indicates that the material has begun to leave the warehouse.

[0083] Optionally, the material transfer device may further include a fifth detection component, which is used to detect the inbound area 110 and generate an outbound completion signal when the material has completely entered the outbound area 120 from the inbound area 110. The fifth detection component is electrically connected to the control device and sends the outbound completion signal to the control device, which performs corresponding actions upon receiving the outbound completion signal.

[0084] As an optional implementation, the fifth detection component includes a fifth detection signal transmitter 510 and a fifth detection signal receiver 520. Both the fifth detection signal transmitter 510 and the fifth detection signal receiver 520 are located at the boundary between the inbound area 110 and the outbound area. The fifth detection signal transmitter 510 and the fifth detection signal receiver 520 are located on both sides of the material transfer platform 100, with the signal transmitting surface of the fifth detection signal transmitter 510 and the signal receiving surface of the fifth detection signal receiver 520 facing each other.

[0085] The fifth detection signal receiver 520 is used to generate the outbound completion signal when it does not receive a signal transmitted by the fifth detection signal transmitter 510.

[0086] The fifth detection component is electrically connected to the control device and sends the outbound completion signal to the control device. The control device is used to control the third detection component to restart detection after receiving the outbound completion signal.

[0087] The fifth detection signal transmitter 510 can be an optical signal transmitter, and the fifth detection signal receiver 520 can be an optical signal receiver.

[0088] In the warehousing system, after material 800 enters the receiving area 110, it is transferred to the storage area by the handling robot 500. When the material leaves the warehouse, it is also handled by the handling robot 500 to move the material from the storage area to the material transfer station 100. There are a large number of handling robots 500 in the entire warehousing system, which may cause the handling robots to queue up.

[0089] To prevent the moving transport robot 500 from colliding with the operator, optionally, such as Figure 3As shown, the material transfer device also includes a separator 600, which is positioned at the junction of the inbound area 110 and the outbound area 120 and extends to both sides of the material transfer platform 100. A transfer window is formed on the separator 600 at the position opposite to the junction of the inbound area 110 and the outbound area 120.

[0090] The separator 600 can be a fence or a partition, which can physically separate the area where the handling robot operates from the area where the operator is active, to ensure the operator's safety. Materials can pass through the handover window to ensure the normal flow of materials in and out of the warehouse.

[0091] Optionally, such as Figure 3 As shown, the material transfer device may further include a signal indication device 700, which is disposed on the top of the separator 600.

[0092] Optionally, the signal indicator 700 can be a signal light, which can remind the operator whether the status of the material being pushed is normal by flashing the signal light.

[0093] As a second aspect of this utility model, a warehousing system is also provided, the warehousing system including a control device and a material transfer device, wherein the material transfer device is the material transfer device provided in the first aspect of this utility model.

[0094] The control device is electrically connected to the first detection component; the control device is used to determine whether the material handover is normal based on the time difference between the first detection signal and the second detection signal when it receives the first detection signal and the second detection signal.

[0095] Optionally, the warehousing system further includes a signal prompting device, which is electrically connected to the control device. The control device is used to control the signal prompting device to issue corresponding prompting information when an abnormality is determined in the material handover.

[0096] Optionally, the warehousing system further includes an inbound workstation. In this invention, the inbound workstation can be a static shelf or a dynamic conveyor line.

[0097] The following is a brief description of the specific working process of the warehousing system.

[0098] When the inbound / outbound workstation is in the form of a static shelf, the inbound / outbound process is as follows:

[0099] When material 800 is put into storage, the operator manually pushes material 800 along the guide plate through the transfer window. The material first blocks the first detection signal transmitter 211 and the second detection signal transmitter 221. Since material 800 is a regular material that is symmetrical from left to right, the time delay of triggering the first detection signal receiver 212 and the second detection signal receiver 222 is very small. The control device has a preset time delay threshold. When the time delay between the first response signal generated by the first detection signal receiver 212 and the second response signal generated by the second detection signal receiver 222 is less than the preset time delay threshold, the control device determines that material 800 has passed through the transfer window in a set posture. At this time, the control device sends a command to disable the intrusion alarm function of the third detection component, so that material 800 can pass through normally. Once material 800 has fully entered the storage area, the fourth detection signal receiver 420 will be triggered, and the person's hand has left the hand-to-hand window, meaning the third detection component has not detected the intrusion of the person's hand. At this time, the control device determines that material 800 is in place and in a safe state, and can send a material handling signal to the control mechanism of the mobile robot, while simultaneously restarting the intrusion alarm function of the third detection component.

[0100] As mentioned above, if a human hand or other abnormal material enters the handover window, and neither the first detection component nor the second detection component is triggered, or if the delay of triggering the first detection signal receiver 212 and the second detection signal receiver 222 exceeds the preset delay threshold, the control device will determine it as an abnormal intrusion and immediately trigger an abnormal intrusion alarm.

[0101] When material 800 is being processed out of the warehouse, the mobile robot 500 transports material 800 into the inbound / outbound workstation. The fourth detection component is triggered first, and the control device determines that material is being processed out of the warehouse. Then, the material triggers the first and second detection components. When the time delay between the first detection signal generated by the first detection signal receiver 212 and the second detection signal generated by the second detection signal receiver 222 is less than the threshold, the control device determines that the outbound process is normal. Finally, the material triggers the fifth detection component, and the system determines that the material has been processed and is in place. When all three conditions are met, the handover window is blocked by the material, eliminating the risk of abnormal intrusion. The control device sends a command to disable the intrusion alarm function of the third detection component, allowing personnel to normally reach into the handover window to retrieve the material. After the material is removed from the inbound / outbound workstation, once the fourth, fifth, and third detection components have successively stopped detecting material signals, the control device restarts the intrusion alarm function of the third detection component, restoring the initial state.

[0102] In one feasible implementation, the control device can control the signal lights to output different working status indications according to the different sensing states of the detection components, such as initial idle state, illegal intrusion state, material entering the warehouse waiting for the mobile machine to pick up the box, material leaving the warehouse waiting for manual picking up the box, etc., which can be customized according to specific needs.

[0103] In one feasible implementation, when the inbound / outbound workstation is a dynamic conveyor line, the operator does not need to pass through the handover window when handing over tasks, so the fourth and fifth detection components can be eliminated.

[0104] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
