Description

Technical Field

[0001] This utility model relates to the field of logistics sorting equipment technology, and in particular to a multi-specification parcel sorting chute. Background Technology

[0002] With the rapid development of the modern logistics industry, the sorting efficiency and accuracy of express parcels have become key factors affecting the speed of logistics turnover. Among them, sorting chutes, as a basic equipment that uses gravity to transport and divert parcels, are widely used in major logistics transfer centers because of their simple structure and lack of additional power drive.

[0003] However, traditional parcel sorting chutes mostly use a fixed-width channel structure and a sliding bottom with a constant coefficient of friction. This fixed structure is inadequate when dealing with "multi-specification" parcels with huge differences in size and weight in the current logistics scenario. When large parcels enter narrow chutes, they are prone to jamming or even blockage, causing the entire sorting line to stop. When heavy parcels enter chutes with low friction, they are often damaged by impact due to excessive sliding speed. Existing chute equipment lacks the ability to adaptively adjust according to the real-time parameters of the parcels, which seriously restricts the smoothness and safety of sorting operations.

[0004] Therefore, this utility model proposes a multi-specification package sorting chute to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of multi-size package sorting chute, the fixed channel width cannot be adapted to packages with huge size differences, which makes it easy to blockage, and the constant friction of the sliding bottom surface causes heavy packages to slide down too fast and be prone to collision damage, this utility model aims to provide a multi-size package sorting chute with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a multi-specification package sorting chute, including: an inner frame and a support; as well as a conveyor belt, a transmission port, a fixing plate, a side plate, a rotating bolt, and a damping strip fixing seat.

[0007] The inner frame is fixedly installed inside the conveyor belt as an internal support skeleton. The support is fixedly connected to the bottom of the inner frame. The transmission port is fixedly installed on the left side of the conveyor belt. A sensor is fixedly installed on the top of the transmission port. The fixing plate is fixedly connected to the front and rear sides of the inner frame. The side plate is located above the conveyor belt. The rotating bolt is connected between the fixing plate and the side plate. The damping strip fixing seat is fixedly connected to the surface of the conveyor belt.

[0008] Furthermore, the side plate and the fixed plate are adjustablely connected by the rotating bolt. The rotating bolt is used to drive the side plate to move horizontally and laterally relative to the center line of the conveyor belt, thereby changing the spacing between the side plates to accommodate different sizes of wrapping. The damping strip fixing seat is combined with the surface of the conveyor belt by a fixed connection, and the damping strip fixing seat is used to provide adjustable frictional resistance.

[0009] Preferably, screws are threaded at the four corners of the bottom of the transmission port, and the transmission port is fastened to the supporting structure below by the screws. This multi-point threaded connection not only facilitates the disassembly and maintenance of the transmission port, but also effectively improves the stability of the connection structure and prevents loosening under the vibration environment of continuous passage of the package.

[0010] Preferably, the damping strip fixing seat is equipped with a miniature cylinder inside. The miniature cylinder is used to adjust the rigidity of the damping strip fixing seat or the height of the surface protrusion. By controlling the extension and retraction of the miniature cylinder, the physical characteristics of the contact surface between the damping strip fixing seat and the package can be changed, thereby providing differentiated frictional resistance for packages of different weights and realizing intelligent control of the sliding speed.

[0011] Preferably, a drop plate is fixedly connected to both the front and rear sides of the middle section of the inner frame. The drop plate is vertically arranged at the edge of the conveyor belt and located behind the side plate. The drop plate plays a role in lateral limiting and protection, effectively preventing packages from accidentally slipping off the side due to deviating from the center during rapid sliding, thus ensuring the safety of the sorting process.

[0012] Preferably, a guide plate is provided at the end of the conveyor belt. The guide plate has an inwardly contracting or a specific angled guide surface. The guide plate is used to help correct the slip direction of the package. In particular, for irregularly shaped packages such as cylindrical ones that are prone to disorderly rolling, the guide plate can limit their rolling trajectory and guide them to accurately enter the next stage of conveying equipment.

[0013] Preferably, the inner wall of the fixed plate is threadedly connected to the side plate via the rotating bolt. The rotating bolt passes through the threaded hole on the fixed plate and is rotatably connected to the side plate. When the drive source drives the rotating bolt to rotate, the rotational motion is converted into axial linear motion using the thread transmission principle, thereby smoothly and accurately pushing the side plate to adjust its position.

[0014] Preferably, the inner frame serves as the internal support skeleton of the conveyor belt, and the conveyor belt is supported by the support. The geometric contour of the inner frame is closely fitted with the inner surface of the conveyor belt, providing all-round structural support for the conveyor belt, preventing collapse and deformation due to bearing heavy packages, and ensuring the flatness of the sliding surface.

[0015] Preferably, the sensor is used to detect the size and weight of the package and collect parameters. As the sensing front end of the system, the sensor can acquire the physical characteristic data of the package in real time and feed it back to the control system, providing accurate data support for the adjustment of the side plate width and the friction adjustment of the damping strip fixing seat, and realizing the intelligent adaptive operation of the sorting chute.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a sensor at the top of the transmission port to detect the package size in real time, and cooperating with the controller to control the drive source to drive the rotating bolt to rotate, thereby driving the side plate to perform horizontal lateral extension and retraction relative to the fixed plate to adjust the internal width of the chute, solves the problem that the fixed width of the existing sorting chute is difficult to adapt to multiple package sizes, which easily leads to blockage or excessive gaps. It achieves the effect of automatically adapting to the passage of packages of different sizes, effectively preventing blockage inside the chute, and improving the versatility and sorting efficiency of the sorting device.

[0017] 2. This utility model solves the problem of uncontrollable downward speed of packages of different weights due to constant friction during sliding by fixing a damping strip fixing seat on the surface of the conveyor belt and using the package weight data detected by the sensor to control the action of the internal micro cylinder to adjust the hardness or protrusion height of the damping strip. It achieves the effect of dynamically adjusting the downward friction resistance according to the package weight, increasing the friction for heavy packages to prevent excessive downward speed, and ensuring the stability and safety of the package sorting process.

[0018] 3. This utility model solves the problem that cylindrical and other irregularly shaped packages are prone to disorderly rolling or lateral sliding during the sliding process by setting a guide plate with a specific guide surface at the end of the conveyor belt and cooperating with the drop plate set in the middle section of the chute for lateral limiting. It achieves the effect of assisting in correcting the sliding direction of the package, limiting the rolling trajectory of irregularly shaped packages, and ensuring that the package slides accurately and smoothly into the next level of sorting area along the preset path.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a multi-size package sorting chute, which aims to solve the structural defects in the prior art that cause the sorting chute to be easily blocked due to the variety of package sizes and the difficulty in controlling the sliding speed.

[0023] like Figure 1 As shown, the multi-size package sorting chute includes an inner frame 10 and a support 11 fixedly connected to the bottom of the inner frame 10. The support 11 is used to stably support the device on the ground. The inner frame 10 is fixedly installed inside the conveyor belt 7 as an internal support skeleton. The geometry of the inner frame 10 is adapted to the inner contour of the conveyor belt 7. The conveyor belt 7 covers the surface of the inner frame 10. The conveyor belt 7 serves as an inclined conveying base surface to support the packages for sliding movement. The conveyor belt 7 is supported by the support 11 fixedly connected to the bottom of the inner frame 10.

[0024] like Figure 1 and Figure 2 As shown, a transmission port 1 is fixedly installed on the left side of the conveyor belt 7, i.e., the feeding end. The transmission port 1 serves as the inlet channel for packages to enter the chute. The transmission port 1 is used to guide and limit the flow of the packages entering. Screws 3 are threaded to the four corners at the bottom of the transmission port 1. The transmission port 1 is fastened to the supporting structure below by the screws 3. The screws 3 are used to ensure the tightness and stability of the connection of the transmission port 1 and prevent the transmission port 1 from loosening during use. A sensor 2 is fixedly installed on the top of the transmission port 1. The sensor 2 is used to detect the size and weight of the package and collect package parameters in real time. The sensor 2 transmits the collected data to the controller, providing a basis for subsequent adjustment of the spacing of the side plate 5 and the parameter adjustment of the damping strip fixing seat 6.

[0025] It also includes a fixed plate 4, a side plate 5, and a rotating bolt 12. The fixed plate 4 and the side plate 5 form a specific width adjustment mechanism through the rotating bolt 12, which is used to accommodate different sizes of packages and prevent the chute from getting blocked.

[0026] Please refer to Figure 4 The core structure is described in detail below. There are at least two fixed plates 4. The fixed plates 4 are symmetrically fixed to the front inner wall and the rear inner wall of the inner frame 10. The inner wall of the fixed plate 4 is provided with threaded holes. The rotating bolt 12 is threaded through the threaded holes of the fixed plate 4 and extends to the inner side of the fixed plate 4. The end of the rotating bolt 12 is rotatably connected to the side plate 5. The side plate 5 is located on both sides above the conveyor belt 7. The side plate 5 is used to limit the lateral movement range of the package. The rotating bolt 12 is used to drive the side plate 5 to reciprocate in the horizontal direction. The controller controls the drive motor to drive the rotating bolt 12 to rotate. When the rotating bolt 12 rotates, it generates axial displacement under the action of the threaded holes of the fixed plate 4, thereby pushing or pulling the side plate 5 to change the distance from the center line of the conveyor belt 7, realizing the dynamic adjustment of the width inside the chute.

[0027] Meanwhile, a damping strip fixing seat 6 is also fixedly connected to the surface of the conveyor belt 7. The damping strip fixing seat 6 is used to adjust the downward friction force according to the weight of the package. The damping strip fixing seat 6 is equipped with a miniature cylinder, which is connected to the air source through an air pipeline. The controller controls the extension and retraction of the miniature cylinder according to the package weight data fed back by the sensor 2. The extension and retraction of the miniature cylinder causes the damping strip on the surface of the damping strip fixing seat 6 to deform or change the height of the protrusion, thereby changing the friction resistance of the damping strip fixing seat 6 to the package. For heavy packages, increasing the height of the damping strip protrusion or the hardness can increase the friction force, prevent the package from sliding down too fast, and ensure the stability of the sorting process.

[0028] For the drive source used to drive the rotating bolt 12 to rotate and the air source device used to drive the micro cylinder to move, those skilled in the art can use conventional methods such as servo motors, stepper motors and small air pumps. The specific installation position and internal structure of the drive source are well known in the art and will not be described in detail here.

[0029] As a preferred embodiment, to prevent packages from falling sideways during the sorting and sliding process, please refer to... Figure 1 The inner frame 10 has a drop plate 8 fixedly connected to the front and rear sides of the middle section. The drop plate 8 is vertically set at the edge of the conveyor belt 7 and located behind the side plate 5. The drop plate 8 is used to prevent the package from sliding to the side. The surface of the drop plate 8 is smooth to reduce the frictional resistance on the side of the package and guide the package to slide smoothly into the sorting outlet.

[0030] As another preferred implementation method, to assist in correcting the direction of package slippage, especially for irregularly shaped packages such as cylindrical packages, please refer to... Figure 1The end of the conveyor belt 7 is fixedly connected to a guide plate 9. The guide plate 9 has an inwardly contracting or a specific angle guide surface. The guide plate 9 is used to limit the rolling trajectory of the package, ensure that the package accurately enters the next level sorting area along the preset path, and prevent the package from rolling or piling up in a disorderly manner at the exit.

[0031] As another preferred embodiment, to ensure the secure connection between transmission port 1 and the lower support structure, please refer to... Figure 1 The four corners at the bottom of the transmission port 1 are provided with mounting holes. The screw 3 passes through the mounting holes and is threaded to the support structure below. The head of the screw 3 is provided with a washer to increase the clamping area and prevent the screw 3 from loosening and causing the transmission port 1 to shake.

[0032] Working principle: When users sort multi-sized packages, the transmission port 1 serves as the inlet channel for packages to enter the chute. The transmission port 1 plays a guiding and flow-limiting role. The sensor 2, which is fixedly installed on the top of the transmission port 1, detects the size and weight of the package. The sensor 2 collects package parameters in real time and transmits them to the controller. The controller makes a judgment based on the feedback data from sensor 2. When sensor 2 detects that packages of different sizes are entering, the controller controls the drive source to drive the rotating bolt 12 to rotate. The rotating bolt 12 drives the side plate 5 to perform horizontal lateral extension and retraction relative to the fixed plate 4. The side plate 5 moves to adjust the width of the slide groove to accommodate packages of different sizes passing through, preventing the packages from getting stuck inside the slide groove. At the same time, the controller adjusts the micro cylinder inside the damping strip fixing seat 6 according to the package weight data. The micro cylinder changes the rigidity or surface protrusion height of the damping strip fixing seat 6, thereby changing the friction resistance of the package sliding down. For heavy packages, the friction is increased to reduce the sliding speed. The damping strip fixing seat 6 ensures the stability of the package sorting process. The package slides down the surface of the conveyor belt 7. The front and rear drop plates 8 in the middle section of the inner frame 10 prevent the package from sliding to the side. The drop plates 8 guide the package to slide smoothly into the sorting outlet. The guide plate 9 at the end of the conveyor belt 7 helps to correct the direction of the package's slide. In particular, it limits the rolling trajectory of irregularly shaped packages such as cylindrical ones. The guide plate 9 ensures that the package moves accurately to the next process along the preset path.
