Description

Technical Field

[0001] This invention relates to the field of palletizing technology, and more specifically to a palletizing and loading system. Background Technology

[0002] With the continuous development of logistics transportation systems, the requirements for transportation efficiency are becoming increasingly higher. Currently, in the process of logistics outbound loading and unpacking, the processes of unpacking, handling, loading, and palletizing are mostly completed manually.

[0003] Therefore, in the entire outbound logistics process, loading workers need to manually complete both unpacking and handling, as well as loading and stacking, which results in high labor intensity and low work efficiency. Summary of the Invention

[0022] Beneficial effects: By setting up a dividing component, the distance between each individual product on the conveying roller can be adjusted to a predetermined distance, so as to ensure that the reversing mechanism will not collide with other individual products when reversing individual products, and at the same time, it can also ensure that there will be no obstruction during normal reversal.

[0023] In one optional embodiment, the box stacking dismantling device further includes:

[0024] A rejection mechanism is disposed between the conveying mechanism and the reversing mechanism along the conveying direction of the loose products; the rejection mechanism rejects the loose products after detecting that the loose products are not in good shape.

Simultaneously, it ensures that all cooperating equipment can be fine-tuned in its position relative to the vehicle according to actual conditions, enabling all cooperating equipment to operate normally. Compared to a system where all cooperating equipment is in a fixed position, this significantly facilitates coordination with the vehicle to be loaded. To a certain extent, this improves work efficiency.

[0068] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0071] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0072] With the continuous development of logistics transportation systems, the requirements for transportation efficiency are becoming increasingly stringent. Currently, in the outbound logistics loading process, the unpalletizing, handling, loading, and palletizing processes are mostly completed manually. Therefore, in the entire outbound logistics process, loading workers need to manually complete both unpalletizing and handling, as well as loading and palletizing, resulting in high labor intensity and low work efficiency.

[0073] In view of this, the present invention provides a palletizing and loading system to solve the problem of low work efficiency caused by manual unpalletizing, handling, loading and palletizing in the entire outbound logistics process.

[0074] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0075] According to an embodiment of the present invention, in one aspect, a palletizing and loading system is provided, which includes a depalletizing robot 7, a box-palletizing and splitting device 4, a telescopic conveyor device 3, and a loading and palletizing device 2.

[0076] Specifically, in this embodiment of the invention, a depalletizing robot 7 is disposed in a depalletizing area, where product stacks are placed, and the depalletizing robot 7 is adapted to retrieve product stacks from the depalletizing area. Regarding the arrangement of the depalletizing robot 7, it can be fixedly disposed in the depalletizing area, or it can be movable. When the depalletizing robot 7 is fixedly disposed in the depalletizing area, the box-pallet splitting device 4 needs to be located within the operating range of the robotic arm of the depalletizing robot 7, thereby ensuring that the depalletizing robot 7 can properly place the product stacks onto the box-pallet splitting device 4.

[0077] The number of depalletizing robots 7 can be adjusted according to the actual number of boxes and pallets that the depalletizing equipment 4 receives, as long as the handling speed of the depalletizing robots 7 matches the receiving speed of the depalletizing equipment 4.

[0078] Furthermore, in this embodiment of the invention, the palletizing and splitting device 4 is provided with an input side and an output side. The input side is used to receive the product stack from the depalletizing robot 7, break down the product stack into individual products, and then transport them outward through the output side. One end of the telescopic conveyor 3 is connected to the output side; the other end of the telescopic conveyor 3 transports the individual products to the loading and palletizing device 2. The telescopic conveyor 3 is telescopic, and its length can be adjusted according to actual needs to adapt to different working spaces or conveying distances. For example, it can be a telescopic belt conveyor or a roller telescopic conveyor.

[0079] In actual operation, the other end of the telescopic conveyor 3 is connected to the loading and palletizing equipment 2, which means that the length of the telescopic conveyor 3 is related to the loading position of the loading and palletizing equipment 2. When the loading and palletizing equipment 2 just begins loading, it is at the front of the vehicle 1 to be loaded, so the length of the telescopic conveyor 3 is relatively long. When the loading and palletizing equipment 2 is about to finish loading, it is at the rear of the vehicle 1 to be loaded, so the length of the telescopic conveyor 3 is relatively short.

[0080] Of course, this embodiment is merely an example of a specific type of telescopic conveyor device 3, but it does not limit the scope of the invention. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect can be achieved.

[0081] Furthermore, in this embodiment of the invention, the loading and palletizing device 2 is connected to the other end of the telescopic conveyor 3. The loading and palletizing device 2 is adapted to receive the loose products from the telescopic conveyor 3 and form loading pallet groups, and then palletize and load the loading pallet groups onto the vehicle.

[0082] With this configuration, this embodiment of the invention, by setting up the palletizing and splitting device 4, can automatically break down product stacks into individual products, thus eliminating the need for loading workers to manually unpile product stacks sequentially in the warehouse, significantly improving unpile efficiency. This embodiment of the invention, by setting up the telescopic conveyor 3, ensures a real-time supply of individual products during the actual loading process, as the loading and palletizing device 2 continuously moves. Furthermore, this embodiment of the invention, by setting up the loading and palletizing device 2, can automatically arrange individual products into loading stacks, thereby directly palletizing and loading these stacks onto trucks, further improving the efficiency of loading and palletizing, and ultimately improving logistics efficiency.

[0083] Furthermore, in an optional embodiment, the box stacking dismantling device 4 includes a dismantling mechanism 42, a conveying mechanism 43, and a reversing mechanism 44.

[0084] Specifically, in this embodiment of the invention, the disassembly mechanism 42 is provided with an input side and an output side, wherein the input side is used to receive product stacks. The input side may also be provided with a receiving roller 41, which then transports the product stacks to the disassembly mechanism 42. After the disassembly mechanism 42 disassembles the product stacks into individual products, they are output outwards through the output side. The disassembly mechanism 42 can employ a differential roller set or a Mecanum roller set 421. Of course, this embodiment is merely an example illustrating a specific type of disassembly mechanism 42, and is not intended to limit its application. Those skilled in the art can modify it according to actual circumstances, as long as the same technical effect is achieved.

[0085] Furthermore, in this embodiment of the invention, the conveying mechanism 43 is connected to the output side, and the conveying mechanism 43 continues to convey the loose products. The output mechanism can be an output roller group arranged along the conveying direction of the loose products, or it can be a conveyor belt. Of course, this embodiment is merely an example of a specific type of conveying mechanism 43, but it is not intended to limit it. Those skilled in the art can make changes according to actual conditions, as long as the same technical effect is achieved.

[0086] Furthermore, in this embodiment of the invention, the reversing mechanism 44 is disposed at one end of the conveying mechanism 43 away from the output side. The reversing mechanism 44 adjusts the placement direction of the loose products according to a predetermined procedure.

[0087] In other words, after setting the working mode of the reversing mechanism 44 according to the type of product stack to be destabilized, the decomposition mechanism 42 and the output mechanism automatically decompose and transport the product stack. The reversing mechanism 44 only needs to place the scattered products according to the prescribed quantity.

[0088] With this configuration, the decomposition mechanism 42 in this embodiment of the invention can directly decompose an entire stack of products into individual products, thus eliminating the need for loading workers to manually unstack the product stacks in the warehouse, greatly improving destacking efficiency. Furthermore, in this embodiment, the reversing mechanism 44 can directly adjust the placement direction of the individual products, so that after being shipped out, the individual products can be directly stacked into the loading stacks required for loading, and the loading stacks can be directly assembled into the truck without manual re-stacking, significantly improving stacking efficiency.

[0089] Further, in an optional embodiment, the disassembly mechanism 42 includes a Mecanum wheel set 421 and a conveyor belt 422. Specifically, in this embodiment, the Mecanum wheel set 421 is provided with an input side and an output side, and the Mecanum wheel set 421 is used to disassemble the product stack into individual products. Further, the conveyor belt 422 is disposed on the Mecanum wheel set 421. Along the output direction of the individual products, the conveyor belt 422 is disposed at the end of the Mecanum wheel set 421. After the Mecanum wheel set 421 breaks up the product stack, the resulting individual products are transported to the end of the Mecanum wheel set 421, so that the surface of the conveyor belt 422 contacts the surface of the individual products. Since the conveying direction of the conveyor belt 422 is the same as the output direction of the individual products, the individual products continue to be output outward under the driving action of the conveyor belt 422.

[0090] Further, in an optional embodiment, the conveying mechanism 43 includes a conveying roller 431 and a dividing assembly 432. Specifically, in this embodiment, one side of the conveying roller 431 is connected to the output side, and the other side of the conveying roller 431 conveys the loose products outward. The dividing assembly 432 is disposed on the conveying roller 431, and at least one dividing assembly 432 is located upstream of the reversing mechanism 44 along the conveying direction of the loose products. The dividing assembly 432 may be a dividing plate.

[0091] Because there are many loose products, and the distance between adjacent loose products remains relatively short after being broken down, a blocking mechanism is needed to separate them. When a loose product is conveyed to the vicinity of the reversing mechanism 44, the reversing mechanism 44 is performing reversing operations on other loose products, so the blocking component 432 needs to block the current loose product. After the other loose products have completed their reversing operations, the blocking mechanism moves away from the conveying roller 431, allowing the next loose product to enter the reversing mechanism 44. This process continues.

[0092] With this configuration, the present invention embodiment can adjust the distance between each individual product on the conveying roller 431 by setting the dividing component 432, and adjust the distance between each individual product to a predetermined distance, so as to ensure that the reversing mechanism 44 will not collide with other individual products when reversing individual products, and at the same time, it can also ensure that there will be no obstruction during normal reversal.

[0093] Furthermore, in an optional embodiment, the box-stacking and dismantling device 4 further includes a rejection mechanism 45, which is disposed between the conveying mechanism 43 and the reversing mechanism 44 along the conveying direction of the loose products. The rejection mechanism 45 rejects loose products that do not meet the shape requirements after detection. The rejection mechanism 45 can be a toggle plate, which directly moves the unqualified loose product away from the conveyor line after detection, and then recycles the unqualified loose product. The rejection mechanism 45 can also be a robotic arm, whose working process is similar to that of a toggle plate, and will not be described in detail here.

[0094] Of course, this embodiment is merely an example of a specific type of rejection mechanism 45, but it does not limit the scope of the invention. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect can be achieved.

[0095] With this configuration, the present invention embodiment can detect unqualified loose products in real time by setting up the rejection mechanism 45, thereby promptly removing unqualified loose products from the queue of loaded products, ensuring that all products in the loading stack are qualified products, which can significantly improve the product qualification rate and thus improve customer satisfaction.

[0096] Furthermore, in an optional embodiment, the loading and palletizing equipment 2 includes a chassis mechanism 21, a lifting mechanism 22, a conveying mechanism 23, a palletizing mechanism 24, and a pushing mechanism 25.

[0097] Specifically, in this embodiment of the invention, the chassis mechanism 21 is provided with a lifting mechanism 22. The lifting mechanism 22 can be, for example, a frame-type lifting frame, a lifting guide rail, or a scissor-type lifting mechanism 22. Of course, this embodiment is merely an example of the specific type of lifting mechanism 22, but it is not intended to limit it. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect is achieved.

[0098] Furthermore, in this embodiment of the invention, the conveying mechanism 23 is mounted on the chassis mechanism 21. One side of the conveying mechanism 23 is connected to the telescopic conveyor 3. After receiving the loose products and conveying them to the other side of the conveying mechanism 23, a loading stack is formed. In this embodiment of the invention, the conveying mechanism 23 can be a conveyor belt or a conveyor roller 431. Of course, this embodiment is merely an example illustrating the specific type of the conveying mechanism 23, but it is not intended to limit it. Those skilled in the art can modify it according to actual conditions, as long as the same technical effect is achieved.

[0099] Furthermore, in this embodiment of the invention, the palletizing mechanism 24 is disposed on the lifting mechanism 22, and the palletizing mechanism 24 is located on the other side of the conveying mechanism 23 and adjacent to the conveying mechanism 23. Under the driving action of the lifting mechanism 22, the palletizing mechanism 24 pallets and loads the loading pallets onto the vehicle after reaching a predetermined height.

[0100] Furthermore, in this embodiment of the invention, a pushing mechanism 25 is disposed on the conveying mechanism 23. The pushing mechanism 25 has a first position for pushing the loading pallet onto the palletizing mechanism 24 and a second position for returning to its original position. That is, after the conveying mechanism 23 transports the loading pallet to its end, the pushing mechanism 25 can promptly push the loading pallet onto the palletizing mechanism 24, and then the pushing mechanism 25 can return to its original position, waiting for the next loading pallet to arrive at the end of the conveying mechanism 23. This reciprocating motion continues.

[0101] As for the implementation method, a photoelectric switch can be installed at the end of the conveying mechanism 23. The photoelectric switch is communicatively connected to the ejection mechanism 25. After the conveying mechanism 23 transports the loaded pallet to its end, the photoelectric switch can receive a signal, so that the ejection mechanism 25 can promptly push the loaded pallet onto the palletizing mechanism 24. Of course, other communication methods can also be used, as long as the communication connection between the ejection mechanism 25 and the conveying mechanism 23 can be guaranteed.

[0102] With this configuration, this embodiment of the invention, through the setting of the conveying mechanism 23 and the palletizing mechanism 24, can automatically form products into loading pallets. Regarding the formation method, palletizing software can automatically adjust the product placement according to specifications during external conveyor belt transport, or the product placement can be adjusted manually. The palletizing mechanism 24 can directly palletize and load the loading pallets, thereby improving the efficiency of loading and palletizing, and thus improving logistics efficiency. It avoids relying on human experience for product loading quality, comprehensively improving the overall quality of product loading. Furthermore, it can also realize the flower-arranged palletizing of boxed products, with pallet stability superior to manual methods. It is currently the only loading and palletizing equipment 2 in the industry with flower-arranged palletizing function and application cases with loading volumes exceeding 70 trucks.

[0103] Further, in an optional embodiment, the conveying mechanism 23 includes a first conveyor belt 231, a second conveyor belt 233, and a reversing conveyor group 232. Specifically, in this embodiment, the first conveyor belt 231 is disposed on one side of the chassis mechanism 21 and connected to the telescopic conveyor device 3. The second conveyor belt 233 is disposed on the other side of the chassis mechanism 21, and the second conveyor belt 233 and the first conveyor belt 231 are connected by the reversing conveyor group 232, so that the first conveyor belt 231 and the second conveyor belt 233 form an L-shaped structure. The loading stack is formed at the end of the second conveyor belt 233. The reversing conveyor group 232 can also be composed of Mecanum wheel sets 421.

[0104] In actual operation, loose products are first transferred from the telescopic conveyor 3 to the first conveyor belt 231, and then the conveying direction of the loose products is changed on the reversing conveyor group 232, so that the loose products are transported towards the second conveyor belt 233. Since the loose products have already been reversed by the reversing mechanism 44, they will be automatically assembled into a stack after being transported to the end of the second conveyor belt 233, without the need for manual adjustment, thus achieving full automation.

[0105] Further, in an optional embodiment, the palletizing mechanism 24 includes a palletizing platform 241 and a pusher assembly 242. Specifically, in this embodiment of the invention, the palletizing platform 241 is used to receive the loading pallets pushed out by the ejection mechanism 25, and the pusher assembly 242 is used to push out all the loading pallets on the palletizing platform 241 for palletizing and loading.

[0106] In actual operation, after the loading stack has been assembled at the end of the second conveyor belt 233, it can be directly pushed onto the palletizing platform 241 by the pushing mechanism 25. Then, driven by the lifting mechanism 22, the palletizing platform 241 automatically adjusts the palletizing height according to the actual palletizing situation. After the height is determined, the loading stack is pushed to the palletizing position by the pusher assembly 242, thus completing the automatic palletizing. After all the palletizing at the current position is completed, the loading and palletizing equipment 2, driven by the chassis mechanism 21, moves a certain distance toward the rear of the vehicle 1 to be loaded, and performs palletizing at the next palletizing position until the vehicle 1 to be loaded is fully palletized.

[0107] Furthermore, in an optional embodiment, the palletizing and loading system further includes a positioning calibration device 5, which is disposed in the loading area. The positioning calibration device 5 is adapted to house the pallet unpacking device 4, the telescopic conveyor device 3, and the loading and palletizing device 2. The positioning calibration device 5 has a movable working state and performs position calibration with the vehicle 1 to be loaded by moving it.

[0108] Before loading, the vehicle to be loaded 1 needs to be parked in the loading area, close to the positioning calibration device 5. Currently, because different specifications of vehicles 1 have different widths and heights, the loading and palletizing equipment 2 may not be able to drive onto the vehicle 1 properly. Before loading, a driving platform is often installed at the rear of the vehicle 1 to facilitate the loading and palletizing equipment 2 to drive onto the vehicle 1 via the ramp. However, in this embodiment, there is no need to use a driving platform. The positioning calibration device 5 can be continuously moved to calibrate its position with the vehicle 1, making the bottom of the cargo box of the vehicle 1 flush with the bottom of the loading and palletizing equipment 2, thus ensuring that the loading and palletizing equipment 2 can drive onto the vehicle 1 properly.

[0109] With this configuration, the positioning and calibration device 5 in this embodiment of the invention allows the loading and palletizing device 2 to be easily moved directly onto the vehicle 1 to be loaded. Simultaneously, it ensures that all cooperating devices can be fine-tuned in their positions relative to the vehicle 1 according to actual conditions, enabling all cooperating devices to operate normally. Compared to having all cooperating devices in fixed positions, this significantly facilitates cooperation with the vehicle 1. To a certain extent, it can improve work efficiency.

[0110] Further, in an optional embodiment, the positioning calibration device 5 further includes a load platform, a power unit, drive wheels, and multiple lifting legs. Specifically, in this embodiment, the load platform is adapted to house the pallet unpacking device 4, the telescopic conveyor device 3, and the loading and palletizing device 2. The power unit is located on the load platform, and multiple lifting legs are located at the bottom of the load platform to support it. The height of the load platform can be adjusted by the lifting legs. The drive wheels are located at the bottom of the lifting legs, and the drive wheels are connected to the power unit via a transmission device. The power unit can be a motor, and the transmission device can be a power transmission screw. Under the driving action of the power unit, the drive wheels drive the load platform to move.

[0111] With this configuration, the lifting outriggers and drive wheels in this embodiment of the invention enable the load platform to move all the cooperating equipment in both horizontal and vertical directions, thus facilitating easier coordination with the vehicle 1 to be loaded. This can improve work efficiency to a certain extent.

[0112] Furthermore, in an optional embodiment, the palletizing and loading system further includes a product receiving device 6, which receives product stacks in pallet units and transports the pallets to the depalletizing area for the depalletizing robot 7 to pick up the product stacks. In this embodiment of the invention, product stacks are delivered to the depalletizing area in pallet units, with a certain number of product stacks placed on each pallet, and the depalletizing robot 7 can directly pick up the product stacks from the pallets.

[0113] Furthermore, in an optional embodiment, the product receiving device 6 includes a receiving station 61, a buffer station 62, a depalletizing station 63, and a return station 64.

[0114] Specifically, in this embodiment of the invention, receiving station 61 is used to receive product stacks in pallet units and to transport the pallets containing the product stacks. After receiving the pallets containing the product stacks, buffering station 62 buffers the pallets containing the product stacks, and then continues to transport the pallets containing the product stacks according to the actual working situation of the depalletizing robot 7. After the pallets containing the product stacks are transported to depalletizing station 63, the depalletizing robot 7 removes the product stacks from the pallets. After all the product stacks on the pallets are removed, depalletizing station 63 continues to transport the empty pallets to return station 64. Return station 64 receives the empty pallets and performs stacking and sorting.

[0115] The overall working process of this embodiment is as follows:

[0116] Step 1: The box-stacking and unpacking equipment 4, the telescopic conveyor equipment 3, and the loading and palletizing equipment 2 are mounted on the load platform of the positioning calibration equipment 5. After the vehicle to be loaded 1 is in place, the load platform drives the drive wheel to complete the left and right movement through the motor power output of the power transmission screw of the positioning calibration equipment 5. The left and right movement is completed through the lifting outriggers, so as to realize the position calibration of the palletizing and loading system with the vehicle to be loaded 1. After the calibration is completed, the loading and palletizing equipment 2 enters the front of the compartment of the vehicle to be loaded 1 and is positioned.

[0117] Step 2: The product stacks are delivered to the receiving station 61 of the product receiving equipment 6 in pallet form. They are transported by pallet and pass through the buffer station 62 before arriving at the depalletizing station 63. The depalletizing robot 7 takes the product stacks from the pallet and the empty pallet continues to move forward to the return station 64 for stacking.

[0118] Step 3: The depalletizing robot 7 uses a vacuum suction cup to pick up the entire stack of products in one go and place it onto the receiving roller 41 of the box stacking and depalletizing equipment 4;

[0119] Step 4: The receiving roller 41 transports the product stack to the disassembly mechanism 42. The conveyor belt 422 breaks down the product stack into individual products through the differential speed of the Mecanum pulley set 421 and transports them to the conveyor roller 431. Then, the spacing between two adjacent individual products is increased by the dividing assembly 432. After passing through the rejection mechanism 45 to reject unqualified individual products, the reversing mechanism 44 turns the individual products as needed.

[0120] Step 5: After turning, the loose products are transported to the conveying mechanism 23 of the loading and palletizing equipment 2 via the telescopic conveyor 3;

[0121] Step 6: Loose products are transported via the first conveyor belt 231, the reversing conveyor group 232, and the second conveyor belt 233 of the conveying mechanism 23. After reaching the end of the second conveyor belt 233, half-layer stacking is completed. Then, the pushing mechanism 25 pushes the products onto the stacking platform 241 of the stacking mechanism 24. After the stacking platform 241 completes the stacking and arrangement, a loading stack is formed. Then, the lifting mechanism 22 controls the stacking platform 241 to be raised and lowered to the designated stacking position, and the pushing box assembly 242 pushes the loading stack out and places it.

[0122] Step 7: After placing one stack of loading pallets, the loading and palletizing equipment 2 moves back to the next stack placement position via the chassis mechanism 21. Steps 2 to 6 are repeated until the entire vehicle 1 to be loaded is stacked.

[0123] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
