Description

Technical Field

[0001] This utility model relates to the field of logistics sorting technology, specifically a logistics sorting machine with a material drop protection structure. Background Technology

[0002] With the rapid development of e-commerce, the logistics industry is facing unprecedented challenges and opportunities. To improve efficiency and reduce costs, automated equipment is being used more and more widely in logistics centers, among which logistics sorting machines, as one of the core pieces of equipment, play a crucial role in handling massive volumes of parcels.

[0003] The patent with publication number CN216225485U discloses logistics sorting equipment, including a conveyor. Support plates are provided on both sides of the conveyor, and support frames are installed at the bottom of both support plates. One support plate has multiple equally spaced guide ramps on its side away from the conveyor, and the other support plate has a fixed platform on its side away from the conveyor. Collection carts are located at the bottom of the guide ramps. The top of the fixed platform has multiple hollow columns adapted to the guide ramps. The inner circumference of the hollow columns has a lifting assembly for adjusting the working height. The bottom of the inner circumference of the collection cart has two symmetrically distributed sliding tracks, and the inner circumference of the collection cart has a protective assembly connected to the sliding tracks for buffering.

[0004] However, the aforementioned device has the following problems in use: the fixed position of the discharge port means that items must fall directly into the collection container from a relatively high position. This significant drop can easily damage fragile or high-value items. Furthermore, because the discharge port cannot be flexibly adjusted according to actual needs, the distribution of materials in the collection box is often uneven, easily leading to localized accumulation. This situation not only limits the effective utilization of storage space but also further affects overall storage efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a logistics sorting machine with a material drop protection structure, which can realize the automatic identification, classification and layer-by-layer placement of items, and effectively reduce the risk of damage to items during the handling process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A logistics sorting machine with a material drop protection structure includes a machine body and a collection box. The machine body is equipped with a conveying device and an identification device. The machine body is equipped with a material distribution mechanism at equal intervals. The machine body is also equipped with a distribution bracket at equal intervals. A transmission belt is installed on the distribution bracket. The distribution bracket is equipped with a receiving mechanism and a feeding mechanism. A receiving plate is slidably installed inside the collection box. The collection box is equipped with a lifting mechanism.

[0008] Preferably, the material distribution mechanism includes a platform, which is mounted on the machine body. An electric push rod is installed on the platform, and a connecting plate is fixedly installed at the other end of the electric push rod. An elastic pad is embedded in the end of the connecting plate opposite to the electric push rod.

[0009] Preferably, the receiving mechanism includes a servo motor, which is mounted on a bracket. A threaded rod is fixedly mounted on the output end of the servo motor shaft. A nut pair is threadedly mounted on the threaded rod, and a mounting block is fixedly mounted on the nut pair. A buffer pad is embedded in the side of the mounting block away from the servo motor.

[0010] Preferably, the feeding mechanism includes a mounting plate, which is fixedly mounted on the mounting block. An electric telescopic rod is mounted on the mounting plate, and a push plate is fixedly mounted on the other end of the electric telescopic rod.

[0011] Preferably, the lifting mechanism includes a stepper motor and two lead screws. Both lead screws are rotatably installed inside the collection box. A synchronous chain is installed between the two lead screws via a sprocket. Each lead screw is threaded with a lead screw nut, which is fixedly connected to the receiving plate. The stepper motor is installed on the collection box, and the output end of the stepper motor shaft is fixedly connected to one of the lead screws.

[0012] Preferably, a positioning block is fixedly installed on the collection box, and the bracket has a positioning groove adapted to the positioning block at the corresponding position.

[0013] Preferably, a side plate is movably installed on the collection box, and a connecting strip is fixedly installed on the collection box. The connecting strip and the positioning block are provided with grooves that are adapted to the side plate.

[0014] Preferably, the bottom of the collection box is equipped with casters.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention enables precise interception, positioning, and transfer of materials, and gradually fills the same layer of space, ensuring that each layer of space is fully utilized. The stepper motor and lead screw in the lifting mechanism can adjust the height of the receiving plate according to the number of items stored in the collection box, ensuring that the items in each layer are closely arranged, maximizing the use of vertical space. After one layer is filled, it smoothly descends to an appropriate height to prepare for the next layer. This not only achieves efficient space utilization but also minimizes the falling distance of newly arrived items, further reducing impact damage caused by large drops. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figures 1 to 8A logistics sorting machine with a material drop protection structure includes a machine body 1 and a collection box 7. The machine body 1 is equipped with a conveying device 2 and an identification device 3. The conveying device 2 is used to convey the items to be sorted, and the identification device 3 is used to identify information (which can be achieved through RFID or QR code scanning technology) to facilitate sorting activities and to allocate different types of items to the corresponding processing paths. Since the conveying device 2 and the identification device 3 are existing technologies, they will not be described in detail here.

[0028] The machine body 1 is provided with a material distribution mechanism at equal intervals. The machine body 1 is also provided with a distribution bracket 5 at equal intervals. The distribution bracket 5 is equipped with a transmission belt 6. The distribution bracket 5 is provided with a receiving mechanism and a feeding mechanism. The receiving plate 24 is slidably installed inside the collection box 7. The collection box 7 is provided with a lifting mechanism.

[0029] The receiving and feeding mechanisms ensure that the collected items are neatly arranged and not piled up haphazardly. The lifting mechanism can adjust the height of the receiving plate 24 according to the amount of collected items, thereby minimizing the displacement of the items during the falling process and protecting them.

[0030] When the material is moved to the corresponding position, the material sorting mechanism is activated, which pushes the material into the transmission belt 6 on the corresponding sorting bracket 5, thereby realizing the sorting activity.

[0031] The material distribution mechanism includes a platform 4, which is mounted on the machine body 1. An electric push rod 9 is installed on the platform 4. A connecting plate 10 is fixedly installed on the other end of the electric push rod 9. An elastic pad 11 is embedded in the end of the connecting plate 10 away from the electric push rod 9.

[0032] The electric push rod 9 is used to push items for initial sorting, and the elastic pad 11 can reduce the impact force on the items during the transfer process and avoid damage.

[0033] The receiving mechanism includes a servo motor 12, which is mounted on a bracket 5. A threaded rod 13 is fixedly mounted on the output end of the shaft of the servo motor 12. A nut pair 20 is threadedly mounted on the threaded rod 13. A mounting block 14 is fixedly mounted on the nut pair 20. A buffer pad 15 is embedded on the side of the mounting block 14 away from the servo motor 12.

[0034] The start of the servo motor 12 can cause the threaded rod 13 to rotate, and then the nut pair 20 drives the mounting block 14 to move synchronously. The buffer pad 15 on the mounting block 14 can intercept the material on the transmission belt 6. By controlling the position of the mounting block 14, the material can be placed in different positions, so as to successfully fill each layer of space inside the collection box 7.

[0035] The feeding mechanism includes a mounting plate 16, which is fixedly mounted on the mounting block 14. An electric telescopic rod 17 is mounted on the mounting plate 16, and a push plate 18 is fixedly mounted on the other end of the electric telescopic rod 17.

[0036] The activation of the electric telescopic rod 17 causes the push plate 18 to come into direct contact with the items and push them into the collection box 7, thereby realizing the collection activity.

[0037] The lifting mechanism includes a stepper motor 25 and a lead screw 26. There are two lead screws 26, both of which are rotatably installed inside the collection box 7. A synchronous chain 27 is installed between the two lead screws 26 via a sprocket. Each lead screw 26 is threaded with a lead screw nut 28, which is fixedly connected to the receiving plate 24. The stepper motor 25 is installed on the collection box 7, and the output end of the shaft of the stepper motor 25 is fixedly connected to one of the lead screws 26.

[0038] The start of the stepper motor 25 causes the lead screw 26 to rotate. With the presence of the synchronous chain 27, the two lead screws 26 rotate synchronously, thereby driving the lead screw nut 28 and the receiving plate 24 to move vertically. After one layer of space is filled, the receiving plate 24 can be lowered to carry out the filling activity of the next layer.

[0039] Preferably, the sprocket and the synchronous chain 27 should be connected by a toothed drive or a chain drive to ensure the transmission ratio and prevent slippage.

[0040] A positioning block 23 is fixedly installed on the collection box 7. The bracket 5 has a positioning groove 19 that matches the positioning block 23 at the corresponding position. The positioning groove 19 works with the positioning block 23 to improve the stability of the collection box 7.

[0041] A side plate 21 is movably installed on the collection box 7, and a connecting strip 22 is fixedly installed on the collection box 7. The connecting strip 22 and the positioning block 23 have grooves that are adapted to the side plate 21.

[0042] The bottom of the collection box 7 is equipped with casters 8. Preferably, the casters 8 can be a version with brakes to further ensure that the collection box 7 will not move accidentally during use.

[0043] After the collection box 7 is full, the side plate 21 can be smoothly installed in place through the trough. During transportation, the side plate 21 can cover the exposed opening to ensure that the material will not fall off due to bumps and ensure the effect of use.

[0044] The workflow of this utility model is as follows: the items to be sorted are conveyed to the bottom of the identification device 3 via the conveying device 2. The identification device 3 (such as RFID or QR code scanning technology) identifies the item information and provides a basis for subsequent classification.

[0045] Based on the identification results, when an item moves to the corresponding position, the sorting mechanism is activated. The electric push rod 9 pushes the connecting plate 10 and the elastic pad 11, pushing the item onto the transmission belt 6 on the sorting bracket 5, thus achieving preliminary sorting.

[0046] Servo motor 12 drives threaded rod 13 to rotate, causing nut pair 20 to move mounting block 14 and its buffer pad 15 along the direction of transmission belt 6, intercepting and positioning materials at the corresponding positions. Once the materials are correctly placed, electric telescopic rod 17 is activated, and push plate 18 acts directly on the materials, pushing them into the collection box 7 to complete the material collection process. This process involves a gradual filling activity in the same layer of space, allowing the materials to be tightly arranged.

[0047] As one layer of space is filled, the stepper motor 25 starts, driving the lead screw 26 to rotate and ensuring that the two lead screws 26 work synchronously through the synchronization chain 27, so that the lead screw nut 28 drives the receiving plate 24 to descend to an appropriate height, ready for the filling activity of the next layer.

[0048] After the collection box 7 is full, the side plate 21 can be smoothly installed in place through the grooves opened on the connecting strip 22 and the positioning block 23, effectively preventing materials from falling off accidentally due to bumps during transportation.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
