Description

Technical Field

[0001] The present invention relates to the field of warehousing and logistics, and in particular to a cargo pickup trolley. Background Art

[0002] A delivery trolley is a common tool in the warehousing and logistics industry. Workers move the trolley to a warehouse's pickup location to pick up goods. Goods stored there are placed on the trolley and then transported to the next process. With the development of delivery trolleys, some are now equipped with integrated components such as sealers and label printers. Workers can complete steps such as bag sealing and label printing directly on the trolley during the delivery process.

[0003] However, the related functional components of the delivery trolleys in the prior art are all integrated, and the staff cannot adjust the corresponding functional components according to the actual needs of the delivery process. In this case, the staff can only carry the required functional components or move the delivery trolley to other processes for operation.

[0004] Furthermore, the pickup cart is sometimes located to the left of the cart and sometimes to the right. This variable location makes it more difficult for workers to operate. This is especially true for workers who are left-handed. If the pickup cart is only suitable for right-handed workers, these workers will have difficulty using it. Once the pickup cart is full, it needs to be unloaded and emptied before it can be used again. Frequent unloading and picking up of goods affects delivery efficiency.

[0005] The above-mentioned situations make it inconvenient for workers to use the delivery trolley, and the delivery process is time-consuming and labor-intensive. Therefore, how to provide a delivery trolley that can improve the convenience of workers' operation and thus improve the delivery efficiency has become a problem that needs to be solved. Summary of the Invention

[0006] In response to the above problems, the present invention provides a cargo pickup trolley, including: a loading trolley; an operating trolley that can be docked or detached with the loading trolley; an operating table that is arranged on the top of the operating trolley; and multiple functional modules, each of which is configured to be operable by one hand or the other, and can be installed and removed at multiple different positions on the operating table.

[0007] According to the above technical solution, multiple functional modules can be installed and removed at multiple different positions on the operating table, so that the installation position of the functional modules can be adjusted arbitrarily according to the actual application scenario and needs. Workers with right or left hands can configure the position of the functional modules in a way that suits them, and for the situation where the storage location is on the left or right, the staff can adjust the left and right positions of the functional modules, which effectively improves the convenience of the delivery process. The functional modules are installable and removable, and the staff can select the required functional modules for installation and remove the unnecessary functional modules. The operating trolley can be docked or disassembled with the loading trolley, so the operating trolley in this embodiment can be applied to multiple loading trolleys. When the loading trolley is full of goods for delivery, the operating trolley is disassembled from the loading trolley and docked with other loading trolleys. As a result, it can continue to be used for delivery operations without emptying and unloading, which effectively improves the delivery efficiency.

[0008] Preferably, the functional modules include a printing module, a weighing module, a sealing module and a storage module.

[0009] According to the above technical solution, the printing module can print labels, the weighing module can weigh goods, the sealing module can seal packaging bags, and the storage module can be used to place packaging bags and other items. Workers can complete printing, packaging, and weighing operations on the delivery trolley, eliminating the intermediate turnover link of goods delivery, improving the delivery efficiency and the turnover speed of the entire delivery process.

[0010] Preferably, the printing module, the storage module, the weighing module and the sealing module are placed in sequence from left to right or from right to left, and the storage module is installed in front of the printing module.

[0011] According to the above technical solution, this placement method can fully utilize the space on the operating table and improve space utilization. The storage module is installed in front of the printing module, making it convenient for staff to take out the items stored in the storage module.

[0012] Preferably, the sealing module is a heat sealer with a cutter, and the plane where the weighing platform of the weighing module is located is flush with the blade of the cutter.

[0013] According to the above technical solution, the plane where the weighing platform of the weighing module is located is flush with the cutting edge of the cutter, which efficiently utilizes the space. The staff can weigh and seal at the same time without moving.

[0014] Preferably, the sealing module further comprises a magnetic attraction device, which can release the cutter after attracting the cutter for a specified period of time.

[0015] According to the above technical solution, the magnetic device can release the cutter after attracting it for a specified period of time. The staff does not need to press the cutter themselves, but only needs to place the packaging bag on the corresponding position of the cutter to complete the sealing operation, which effectively improves the work efficiency of the sealing operation.

[0016] Preferably, the operating table has a plurality of fixing slots, and the functional module has fixing holes corresponding to the fixing slots.

[0017] According to the above technical solution, the fixing slots and fixing holes cooperate to facilitate the disassembly and assembly of the functional module and the operating table. In addition, the fixing slots have a wider range of adaptability, which can meet the disassembly and assembly requirements of functional modules and operating tables in more different positions.

[0018] Preferably, a self-driving power-assisting device is provided at the bottom of the operating trolley, and the self-driving power-assisting device includes a single fork arm mechanism and a self-driving wheel connected to the single fork arm mechanism.

[0019] According to the above technical solution, the self-driving wheel is installed under a specially designed single fork arm mechanism with a spring shock-absorbing effect inside, ensuring that it can always provide downforce to contact the ground while having a good buffering effect.

[0020] Preferably, it also includes a docking mechanism, which includes a cross bar and a docking hook. The cross bar is set on the loading trolley, and the docking hook is set on the operating trolley.

[0021] According to the above technical solution, when the operating trolley approaches the loading trolley, the docking hook first abuts against the cross bar of the loading trolley. Due to the curvature of the outer edge of the docking hook, during the forward abutment process, the docking hook rotates upward and lifts up, and the hook tip passes through the cross bar and falls under the action of gravity to achieve engagement with the cross bar of the loading trolley. Under the action of gravity, horizontal movement of the operating trolley and the loading trolley in any direction will not cause the hook tip to fall out, and the engagement structure is simple and highly stable.

[0022] Preferably, the docking mechanism further comprises a drawstring and a draw ring, wherein one end of the drawstring is provided with a draw ring, and the other end is provided with a docking hook.

[0023] According to the above technical solution, the pull rope is connected to the docking hook, so that the docking hook and the crossbar of the loading trolley can be released by simply pulling the pull rope in the direction opposite to the engagement direction of the docking hook. In addition, the provision of the pull ring also makes it easier for the staff to perform the pulling operation.

[0024] Preferably, the docking mechanism further includes a guiding device, and the operating trolley docks with the loading trolley along a specified direction of the guiding device.

[0025] According to the above technical solution, during the docking process, the guide devices of the operating trolley and the loading trolley contact and correct their relative positions, allowing them to dock at the docking position. The docking hook then engages with the metal rod to complete the docking. The guide device provides guidance and helps improve the docking efficiency of the operating trolley and loading trolley.

DETAILED DESCRIPTION

[0034] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] This embodiment provides a delivery trolley. Figure 1 FIG is a schematic structural diagram of the operating trolley 100 and the loading trolley 200 according to an embodiment of the present invention. Figure 1 As shown, the delivery trolley includes a loading trolley 200 and an operating trolley 100, with the loading trolley 200 and the operating trolley 100 in an undocked state. The operating trolley 100 is used for various operations and tasks. The operating trolley 100 can be docked or detached with the loading trolley 200. Therefore, the operating trolley 100 in this embodiment can be used with multiple loading trolleys 200. When the loading trolley 200 is fully loaded with goods for delivery, the operating trolley 100 detaches from the loading trolley 200 and docks with another loading trolley 200. This eliminates the need for emptying and unloading and allows continued use for delivery operations, effectively improving delivery efficiency.

[0036] Figure 2 303 and the functional module 302 according to an embodiment of the present invention. Figure 3 Schematic diagram of the structure of the operating table 303 according to an embodiment of the present invention. Figure 2 as well as Figure 3 As shown, the operation trolley 100 further includes an operation table 303, which is disposed on the top of the operation trolley 100. Multiple functional modules 302 are mounted on the operation table 303. The multiple functional modules 302 can be installed and removed from multiple locations on the operation table 303, allowing the installation positions of the functional modules 302 to be adjusted according to actual application scenarios and needs. The detachable function modules 302 allow staff to select the required functional modules 302 for installation or remove the unused functional modules 302.

[0037] The multiple functional modules 302 are configured to be operable with either hand. The left and right sides refer to the left and right sides of the operator's operating trolley 100. The operator can adjust the left and right positions of the functional modules 302 based on their dominant hand or the orientation of the storage location, meeting various usage requirements and effectively improving the convenience of the delivery process.

[0038] In this embodiment, the operating table 303 has multiple fixing slots 10, and the functional modules 302 have fixing holes (not shown) corresponding to the fixing slots 10. Fasteners pass through the fixing slots 10 and are threaded into the fixing holes. The matching fixing slots 10 and fixing holes facilitate assembly and disassembly of the functional modules 302 from the operating table 303. Furthermore, the fixing slots 10 offer a wider range of adaptability, accommodating assembly and disassembly of the functional modules 302 and the operating table 303 in a variety of locations.

[0039] In other embodiments of the present invention, the functional module 302 is not limited to the above connection method with the operating table 303, and other connection methods are also possible. For example, the operating table 303 is provided with a guide rail (not shown), and the functional module 302 cooperates with the guide rail to more conveniently move the functional module 302. Alternatively, the functional module 302 can be connected to the operating table 303 by snapping, thereby facilitating disassembly and installation.

[0040] In this embodiment, the functional module 302 includes a printing module 6, a weighing module 7, a sealing module 8, and a storage module 9. The printing module 6 can print labels or receipts, and the storage module 9 stores packaging bags for goods. After removing goods from storage, staff can remove the bags from the storage module 9 and package the goods.

[0041] The weighing module 7 has a weighing platform 71. After the staff places the goods on the weighing platform 71, the weighing module 7 will detect the weight of the goods. The weight detection of the goods can be completed without the staff manually measuring, thereby improving the weighing efficiency.

[0042] After the product is packaged in the packaging bag, the bag is sealed by a sealing module 8. Sealing module 8 can be a heat-pressed plastic bag sealer, for example. In this embodiment, by placing sealing module 8 on the operating table 303, the packaging and sealing operations for the inspected product can be completed on the operating table 303 of the delivery cart.

[0043] In this embodiment, the sealing module 8 is a heat sealer 81 having a cutter 82 . The heat sealer 81 heats and applies pressure to the packaging bag to complete the sealing operation.

[0044] In some embodiments of the present invention, the plane where the weighing platform 71 of the weighing module 7 is located is flush with the cutting edge of the cutter 82. This makes efficient use of the space available, allowing workers to weigh and seal simultaneously without having to move.

[0045] The sealing module 8 also includes a magnetic attraction device 83, which can release the cutter 82 after being engaged for a specified period of time. The magnetic attraction device 83 with a timed automatic release function is mainly divided into two parts. The upper part is a metal sheet 84 fixed to the heat sealer 81, and the lower part is a magnetic attraction portion 85. The magnetic attraction portion 85 is controlled by an electromagnet through a relay to control the specified length of time of magnetic attraction, and then attracts and releases the upper metal sheet 84. This means that the staff no longer needs to press the cutter 82 themselves, but only needs to place the packaging bag on the corresponding position of the cutter 82 to complete the sealing operation, effectively improving the work efficiency of the sealing operation.

[0046] To sum up, staff can complete printing, packaging, weighing and other operations on the delivery trolley, eliminating the intermediate turnover links of goods delivery, improving the efficiency of goods delivery, and increasing the turnover speed of the entire delivery process.

[0047] Furthermore, the printing module 6, storage module 9, weighing module 7, and sealing module 8 are arranged in sequence from left to right or from right to left, with the storage module 9 mounted in front of the printing module 6. The front side here refers to the side closest to the operator when using the operating trolley 100. This arrangement fully utilizes the space on the operating table 303, improving space utilization. The storage module 9 is mounted in front of the printing module 6, making it convenient for the operator to access items stored in the storage module 9.

[0048] In some other embodiments of the present invention, the placement of each functional module 302 is not limited to the above-mentioned form, and can also be other placement forms, which are not specifically limited here.

[0049] In some other embodiments of the present invention, the functional module 302 is not limited to the above-mentioned printing module 6, weighing module 7, sealing module 8 and placement module 9, but can also be other types of modules, such as a three-dimensional structured light module. The three-dimensional structured light module can quickly detect the three-dimensional size of the product and then calculate the volume of the product.

[0050] Figure 4 Schematic diagram of the structure of the self-driving power-assisting device 13 according to the embodiment of the present invention. Figure 4 As shown, further, a self-driving power-assisting device 13 is provided at the bottom of the operating trolley 100. The self-driving power-assisting device 13 includes a self-driving wheel 132, and a drive motor is provided inside the self-driving wheel 132. The drive motor inside the self-driving wheel 132 can directly drive the self-driving wheel 132 to rotate, thereby achieving a self-driving effect. The self-driving power-assisting device 13 also includes a single fork arm mechanism 131. The self-driving wheel 132 is installed under a specially designed single fork arm mechanism 131 with a spring shock-absorbing effect inside. This ensures that downward force can always be provided to contact the ground while achieving a good buffering effect.

[0051] Figure 5 This is a structural diagram of a delivery trolley according to an embodiment of the present invention. Figure 5 As shown, the operating trolley 100 and the loading trolley 200 are in a docking state. Further, the delivery trolley also includes a docking mechanism for docking or separating the operating trolley 100 and the loading trolley 200. The docking mechanism includes: a guide device 1, a locking device 2 and a pulling device 3.

[0052] Figure 6 Schematic diagram of the structure of the docking mechanism provided by the embodiment of the present invention. Figure 5 as well as Figure 6 As shown, the guide device 1 is an arbitrary guide structure protruding from the operating trolley 100 and / or the loading trolley 200. When the operating trolley 100 and the loading trolley 200 are docked, the guide device 1 can generate a force to correct the relative position between the operating trolley 100 and the loading trolley 200 through the cooperation of the mechanical structure, so that the operating trolley 100 and the loading trolley 200 are docked in the docking position. Figure 2 As shown, the guide device 1 is a plurality of guide plates 11 formed by extending the operating trolley 100 along the docking direction. The guide plates 11 abut against the side surfaces of the support columns 201 of the loading trolley 200 at the docking position. Therefore, during the docking process, the guide plates 11 can pass through the support structure of the loading trolley 200 and abut against the support columns 201, thereby achieving the guiding and limiting of the docking position of the operating trolley 100 and the loading trolley 200, further simplifying the structure of the docking mechanism while ensuring the accuracy of the limitation of the docking position.

[0053] The guide piece 11 includes: a limiting end 11a, which is fixed to the operating trolley 100; a guide end 11b, which is bent by the limiting end 11a in the direction away from the support column 201 of the loading trolley 200. The bent guide end 11b is provided at the end of the guide piece 11, and the docking position of the operating trolley 100 and the loading trolley 200 can be adjusted by the bent inclined surface, thereby expanding the guiding range of the guide piece 11 and making it easier for the staff to perform the docking operation.

[0054] Furthermore, the guide device 1 includes two guide plates 11, and the limit ends 11a of the two guide plates 11 are respectively fixed on both sides of the operating trolley 100, and the guide ends 11b are formed by bending the limit ends 11a inward. The two guide plates 11 are respectively arranged on both sides of the operating trolley 100 and bent inward. Therefore, when the operating trolley 100 is docked with the loading trolley 200, the two guide plates 11 respectively abut against the inner sides of the support columns 201 on both sides of the loading trolley 200, and two opposite abutting forces are generated on both sides of the operating trolley 100. The left and right deviations generated by the operating trolley 100 during the docking process can be corrected by the guide plates 11 on both sides, so that better limiting can be performed during the docking process.

[0055] The engaging device 2 is hinged to the operating trolley 100 and can rotate around the operating trolley 100. When the operating trolley 100 and the loading trolley 200 are docked at the docking position, the engaging device 2 is engaged and fixed with the loading trolley 200 to achieve a stable mechanical engaging structure.

[0056] Figure 7 Schematic diagram of the structure of the locking device 2 provided in an embodiment of the present invention. Figure 7 As shown, the engaging device 2 includes:

[0057] The docking hook 21 is flush with the crossbar 202 of the loading trolley 200. It should be noted that the "flush" here does not specifically mean that the two are arranged in a manner of strict horizontal alignment of the center of gravity, but means that the docking hook 21 and the crossbar 202 are at least partially located on the same horizontal plane.

[0058] The fixed base 22 is fixed to the operating trolley 100, and the hook handle 21a of the docking hook 21 is rotatably connected to the fixed base 22. The rotatable hook is used to realize the engagement between the operating trolley 100 and the loading trolley 200, which has a simple structure and stable engagement.

[0059] The engagement direction of the docking hook 21 and the crossbar 202 of the loading trolley 200 is not limited. The docking hook 21 can be engaged from top to bottom or from bottom to top. Generally, considering the factor of gravity, the docking hook 21 is preferably positioned with the hook tip 21b facing downward, so that it can be engaged under the action of gravity. Under the action of gravity, the hook tip 21b is pressed downward and is not easy to loosen.

[0060] The hook handle 21 a of the docking hook 21 is horizontally disposed on the fixed base 22 , and the outer edge of the docking hook 21 is inclined toward the hook tip 21 b to form a guide surface 21 c . When the operating trolley 100 approaches the loading trolley 200, the outer edge of the docking hook 21 first abuts against the cross bar 202 of the loading trolley 200. In the process of the docking hook 21 and the cross bar 202 of the loading trolley 200 abutting forward, the cross bar 202 of the loading trolley 200 can directly abut against the guide surface 21c, and the docking hook 21 is lifted. As the docking hook 21 is lifted, the cross bar 202 can slide along the inclined guide surface 21c to the hook tip 21b. After the hook tip 21b passes through the cross bar 202, it falls under the action of gravity to achieve engagement with the cross bar 202 of the loading trolley 200. Under the action of gravity, the horizontal movement of the operating trolley 100 and the loading trolley 200 in any direction will not cause the hook tip 21b to fall out. The engagement structure is simple and stable, and the docking process is smoother and faster.

[0061] In this embodiment, the pulling device 3 is a pull cord 31. Because the docking hook 21 is directly fastened by gravity, there is no need for the pulling device 3 to compress it. Therefore, the pulling device 3 only needs to be able to release the engaged state of the docking hook 21. Therefore, a flexible pull cord 31 can be selected as the pulling device 3. One end of the pull cord 31 is fixed to the hook handle 21a of the docking hook 21, and the other end is formed into a pull ring 32. Simply pulling the pull cord 31 in the direction opposite to the engagement direction of the docking hook 21 can release the engagement between the docking hook 21 and the crossbar 202 of the loading trolley 200. In addition, the provision of the pull ring 32 also makes it easier for the operator to perform the pulling operation.

[0062] The pull rope 31 is fixed to one end of the hook handle 21 a away from the fixed base 22 . Since the docking hook 21 rotates around the fixed base 22 , it is more labor-saving to arrange the pull rope 31 away from the fixed base 22 .

[0063] In this embodiment, during the docking process, the support column 201 of the loading trolley 200 first contacts the guide piece 11 protruding from the operating trolley 100. The relative position between the operating trolley 100 and the loading trolley 200 is corrected to the docking position by the contact force between the guide piece 11 and the loading trolley 200. Then, the outer edge of the docking hook 21 of the locking device 2 contacts the cross bar 202 of the loading trolley 200. In the process of the docking hook 21 and the cross bar 202 of the loading trolley 200 contacting forward, the cross bar 202 of the loading trolley 200 directly contacts the cross bar 202 of the loading trolley 200. The docking hook 21 is connected to the guide surface 21c on the outer edge of the docking hook 21, and the docking hook 21 is lifted. As the docking hook 21 is lifted, the cross bar 202 slides along the inclined guide surface 21c to the hook tip 21b. After the hook tip 21b passes through the cross bar 202, it falls under the action of gravity, and engages with the cross bar 202 of the loading trolley 200 to complete the docking; during the separation process of the docking mechanism, the staff first pulls the pull ring 32 upward, and uses the pull rope 31 to drive the docking hook 21 to rotate upward, release the engaging state of the engaging device 2, and then withdraw the operating trolley 100 from the docking position to complete the separation.

[0064] For the docking mechanism provided in this embodiment, when the staff performs the docking operation, they only need to push the docking surface of the operating trolley 100 toward the docking surface of the loading trolley 200 to achieve docking; moving the pulling device 3 and returning the operating trolley 100 can achieve separation. The operation is simple, and the docking process is more accurate and faster. In particular, the docking mechanism in the present invention adopts a purely mechanical structure with fewer components and simple connections between components. It is more durable than an electric structure, and individual components can be replaced individually, which is more flexible and more convenient to maintain.

[0065] It will be understood by those skilled in the art that the specific technical features in each embodiment can be adaptively split or combined. Such splitting or combining of specific technical features will not cause the technical solution to deviate from the principles of the present invention. Therefore, the technical solutions after splitting or combining will fall within the scope of protection of the present invention. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
