Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable weighing technology, and in particular to a conveying device for online dynamic weighing of fruit. Background Technology

[0002] Currently, in order to accommodate the transportation and sorting of large quantities of fruit, assembly lines are usually used to sort the fruit. Before sorting, the fruit usually needs to be weighed, and the weight data of the fruit is used as a reference to grade and transport fruits of different weights.

[0003] Currently, a weighing line is installed before the grading production line. The weighing line includes a frame, a conveyor belt, and a weight sensor. The conveyor belt is set on the frame and rolls along the length of the frame. The weight sensor is located below the conveyor belt. The fruit is located on the conveyor belt and moves with it. When the fruit is conveyed to the top of the sensor, the weight sensor weighs the fruit on the conveyor belt. The data from the weight sensor is transmitted to the grading production line, which then uses the weighing data to grade the fruit.

[0004] Regarding the aforementioned technologies, during the process of conveyor belt transporting fruit, the vibration generated by friction between the conveyor belt and the rollers, as well as the vibration generated by the operation of the frame, can easily interfere with the weight sensor during weighing, causing deviations in the weighing data and affecting the subsequent grading results of the fruit. Therefore, there is an urgent need for a weighing and conveying device that can reduce the deviation of the measurement data. Summary of the Invention

[0005] In order to reduce the data deviation of fruit weighing during the conveyor belt conveying process, this application provides a conveying device for online dynamic weighing of fruit.

[0006] Firstly, this application provides a conveying device for online dynamic weighing of fruit, employing the following technical solution: A conveying device for online dynamic weighing of fruit includes a frame, characterized in that: a conveyor belt and a feeding platform are provided on the frame, the feeding platform is located at the feeding end of the conveyor belt, the conveyor belt has a plurality of positioning holes along its length, the inner diameter of the positioning holes gradually decreases from the upper surface to the lower surface of the conveyor belt, a positioning ring is coaxially provided on the conveyor belt within the positioning hole, the positioning ring is slidably connected to the inner wall of the positioning hole along the axial direction of the positioning hole, and an anti-detachment plate is provided at the end of the positioning ring away from the upper surface of the conveyor belt along the axial direction of the positioning ring. The anti-detachment plate is radially away from the axis of the positioning ring. Extended, the outer diameter of the anti-detachment plate is larger than the maximum inner diameter of the positioning hole. In the initial state, there is a preset distance between the anti-detachment plate and the lower surface of the conveyor belt. A basket net for holding fruit is set inside the positioning ring. The edge of the basket net is fixedly connected to the inner wall of the positioning ring. The basket net is made of deformable material. The frame is provided with several lifting parts corresponding to the anti-detachment plate between the upper and lower conveyor belts. The frame is provided with a lifting part for driving the lifting parts to rise and fall. When the lifting part moves upward to the weighing position, it lifts the anti-detachment plate upward by a preset distance, and the positioning ring separates from the inner wall of the positioning hole.

[0007] By adopting the above technical solution, the conveyor belt and feeding platform transport the fruit. The positioning hole is designed with a structure where the inner diameter gradually decreases from the upper surface to the lower surface, and it cooperates with the anti-detachment plate whose outer diameter is larger than its maximum inner diameter, so that the positioning ring can be reliably kept on the conveyor belt and will not detach upwards. In the initial state, there is a preset distance between the anti-detachment plate and the lower surface of the conveyor belt, providing a basis for the movement distance of the subsequent weighing action. When the fruit falls into the basket made of deformable material and fixedly connected to the inner wall of the positioning ring, the basket can buffer the impact through adaptive deformation and conform to the shape of the fruit, playing a role in positioning and protection. During weighing, the lifting component drives the lifting component to move upward, lifting the anti-detachment plate up the preset distance, so that the positioning ring separates from the inner wall of the positioning hole. At this time, the entire positioning ring assembly is only supported by the lifting component, thereby effectively blocking the path of vibration generated by the frame and conveyor belt operation to the weighing component, significantly improving the accuracy and stability of online dynamic weighing.

[0008] Optionally, the lifting component includes a support plate, two weighing plates, two support plates, and a weight sensor. The support plate is fixedly connected to one output end of the lifting component. The two support plates are fixedly mounted on the support plate. The two weighing plates are parallel to each other. The two ends of each weighing plate are fixedly connected to the two support plates respectively. The weight sensor is fixedly mounted on the weighing plate. During weighing, the weighing plate abuts against the lower end surface of the anti-detachment plate.

[0009] By adopting the above technical solution, the pallet provides a stable lifting base for the entire weighing unit; the two support plates provide reliable mounting points for the weighing plates. The two weighing plates and the two support plates form a structurally stable and force-balanced portal frame weighing frame. When the weighing plate abuts against the lower end face of the anti-slip plate, the load of the positioning ring assembly can be evenly transferred to the weighing frame through the anti-slip plate, and accurately sensed by the weight sensor. This structural design optimizes the transmission path of the gravity force, reduces the adverse effects of off-center loading on measurement accuracy, and ensures more reliable weighing results.

[0010] Optionally, the feeding platform includes a conveyor belt and several diverter plates. The conveyor belt is located at the feeding end of the conveyor belt, and the several diverter plates are fixed on the conveyor belt and evenly distributed along the width direction of the conveyor belt. A conveying trough is formed between adjacent diverter plates, and the number of conveying troughs corresponds to the number of transport lines along the width direction of the conveyor belt.

[0011] By adopting the above technical solution, the diversion plate diverts and guides the fruit, and the conveyor troughs separate and guide the fruit to the corresponding conveyor belt feeding area during feeding. By limiting the number of conveyor troughs to correspond to the number of weight sensors, a one-to-one matching relationship is established between the feeding channels and the subsequent weighing units. This helps to achieve single-fruit, orderly, and channel-separated feeding of fruit to each weighing station, providing an orderly prerequisite for subsequent accurate weighing and grading, and reducing weighing wait times and errors caused by multiple fruits piling up or competing for channels.

[0012] Optionally, the frame is slidably connected with a baffle at the material feeding end of the conveyor belt. The baffle is used to prevent fruit from entering the conveyor belt when it is in the blocking position. The frame is provided with a lifting component 2 for driving the baffle to move vertically.

[0013] By adopting the above technical solution, the baffle can reliably block the fruit when in the blocking position, reducing the probability of it sliding into the conveyor belt before it is ready. When feeding is required, the baffle is moved by the lifting component to release the fruit. This structure realizes mechanical intermittent control of the feeding rhythm, ensuring that the positioning holes on the conveyor belt and the conveying troughs of the feeding platform can accurately align for feeding, effectively reducing the probability of fruit falling, jamming, or being missed due to continuous feeding, and improving the operating order and automation of the device.

[0014] Optionally, the conveyor belt is equipped with multi-color indicator lights that correspond one-to-one with the positioning holes, and the multi-color indicator lights are electrically connected to the weight sensor.

[0015] By adopting the above technical solution, after a weighing operation is completed, a light signal of the corresponding color is emitted intuitively according to the preset weight range to which the weighing result belongs. This allows on-site operators or subsequent picking stations to quickly determine the weight grade of the fruit while it is still on the curved plate without relying on a monitor or central control screen, providing convenience for manual grading confirmation or assisted picking.

[0016] Optionally, a flexible pad is glued to the side of the positioning ring away from the anti-detachment plate, and the flexible pad is in contact with the inner wall of the positioning ring.

[0017] By adopting the above technical solution, when the fruit falls into the net, its surface will first or secondly contact the flexible pad rather than the rigid inner wall of the positioning ring due to possible shaking or indirect impact. The flexible pad, bonded together, forms a secondary flexible buffer interface for the fruit. Working together with the net, it further absorbs the impact energy of the falling fruit, effectively reducing the probability of skin damage caused by direct collision between the fruit and the metal or hard plastic positioning ring, and providing good protection for fragile fruits.

[0018] Optionally, the frame has a rolling belt above the conveyor belt, the rolling belt is covered with soft bristles, and the frame has a number of pressure sensors corresponding to the conveyor troughs along the width of the conveyor belt on the inner side of the conveyor belt.

[0019] By adopting the above technical solution, when the conveyor belt rotates, its soft bristles gently contact the surface of the fruit moving forward in the conveyor trough, helping to remove surface dust or adjust the fruit's posture. Simultaneously, pressure sensors corresponding to each conveyor trough can sense the fruit's passage status in real time. This controls the conveyor belt's rolling speed, reducing the probability of fruit piling up due to excessively fast conveying speed or affecting weighing efficiency due to excessively slow conveying speed.

[0020] Optionally, the frame is provided with indicator light strips on both sides along the width direction, each corresponding to a conveying trough, and the pressure sensor is electrically connected to the indicator light strip.

[0021] By adopting the above technical solution, indicator light strips are installed on both sides of the frame corresponding to the positions of each conveying trough, and pressure sensors are used to sense the amount of fruit in each trough. This allows operators to quickly determine the material fullness of each conveying channel from a distance during equipment operation or inspection, providing guidance for timely adjustment of upstream feeding speed or detection of abnormalities, without having to approach each conveying trough to check one by one.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The conveyor belt and feeding platform transport the fruit. The positioning hole is designed with a structure where the inner diameter gradually decreases from the top surface to the bottom surface. This, combined with an anti-detachment plate whose outer diameter is larger than its maximum inner diameter, ensures the positioning ring is reliably held on the conveyor belt and will not detach upwards. Initially, a preset distance is maintained between the anti-detachment plate and the lower surface of the conveyor belt, providing a basis for the movement distance in subsequent weighing operations. When the fruit falls into a basket made of deformable material and fixedly connected to the inner wall of the positioning ring, the basket can absorb the impact through adaptive deformation and conform to the shape of the fruit, providing positioning and protection. During weighing, the lifting component drives the lifting component to move upwards, lifting the anti-detachment plate a preset distance, separating the positioning ring from the inner wall of the positioning hole. At this point, the entire positioning ring assembly is supported only by the lifting component, effectively blocking the path of vibration generated by the frame and conveyor belt operation to the weighing assembly, significantly improving the accuracy and stability of online dynamic weighing. The pallet provides a stable lifting base for the entire weighing unit; the two support plates provide reliable mounting points for the weighing plates. The two weighing plates and the two support plates form a structurally stable and stress-balanced portal frame weighing system. When the weighing plate abuts against the lower surface of the anti-slip plate, the load of the positioning ring assembly is evenly transferred to the weighing frame through the anti-slip plate, where it is accurately sensed by the weight sensor. This structural design optimizes the transmission path of the gravity force, reducing the adverse effects of off-center loading on measurement accuracy and ensuring more reliable weighing results. The flow divider separates and guides the fruit, while the conveyor troughs separate and guide the fruit to the corresponding conveyor belt feeding area during loading. By limiting the number of conveyor troughs to correspond to the number of weight sensors, a one-to-one matching relationship is established between the feeding channels and the subsequent weighing units. This helps to achieve single, orderly, and channel-separated delivery of fruit to each weighing station, providing an orderly prerequisite for subsequent accurate weighing and grading, and reducing weighing wait times and errors caused by multiple fruits piling up or competing for channels.

Detailed Implementation

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a conveying device for online dynamic weighing of fruit.

[0031] Reference Figure 1 and Figure 2 A fruit online dynamic weighing conveyor includes a frame 1, on which a conveyor belt 2 for conveying fruit and a feeding platform 3 for supplying fruit to the conveyor belt 2 are installed. The feeding platform 3 is arranged at the loading end of the conveyor belt 2 to form a connected conveying path. The conveyor belt 2 is a chain plate conveyor belt 2.

[0032] Reference Figure 3 and Figure 4 The conveyor belt 2 has multiple positioning holes 4 along its length on all chain plates, with each hole 4 penetrating the thickness of the chain plate. The inner diameter of each positioning hole 4 gradually decreases from the opening on the upper surface of the conveyor belt 2 to the opening on the lower surface, forming a variable diameter hole structure with a larger opening at the top and a smaller opening at the bottom. A positioning ring 41 is coaxially installed in each positioning hole 4, with a sliding fit between the outer circumferential surface of the positioning ring 41 and the inner wall of the positioning hole 4, allowing the positioning ring 41 to move relative to the conveyor belt 2 along the axial direction of the positioning hole 4.

[0033] Reference Figure 2 and Figure 4 An anti-detachment plate 42 is provided at one end of the positioning ring 41 facing the lower surface of the conveyor belt 2. The anti-detachment plate 42 extends radially from the end of the positioning ring 41 away from the axis of the positioning ring 41, and its outer diameter is larger than the maximum inner diameter formed by the positioning hole 4 on the lower surface of the conveyor belt 2. In the initial state before the device is weighing, a predetermined gap is maintained between the upper surface of the anti-detachment plate 42 and the lower surface of the conveyor belt 2. A basket 43 for accommodating the fruit to be weighed is fixed inside the positioning ring 41. The edge of the basket 43 is fixedly connected to the inner wall of the positioning ring 41, and the entire basket 43 is made of a deformable material, such as rubber, to cushion and accommodate the fruit.

[0034] Reference Figure 3 and Figure 4In the space between the upper and lower conveyor belts 2, frame 1 has a lifting member 5 located below each anti-detachment plate 42 corresponding to each positioning ring 41. Each lifting member 5 corresponds to each anti-detachment plate 42. The lifting member 5 specifically includes a support plate 51, two weighing plates 52, two support plates 53, and a weight sensor 54. A lifting member 11 is installed between the upper and lower surfaces of the conveyor belt 2 on frame 1. The lifting member 11 can be a cylinder. The lower end of the support plate 51 is fixedly connected to the output end of the lifting member 11. The two support plates 53 are vertically fixed to the upper surface of the support plate 51 and are parallel and spaced apart. The two weighing plates 52 are arranged parallel and spaced apart. The two ends of each weighing plate 52 along its own length direction are fixedly connected to the upper part of the two support plates 53, thereby forming a rectangular frame-shaped weighing structure. The weight sensor 54 is fixedly installed at a preset sensing position on the weighing plate 52.

[0035] Reference Figure 3 and Figure 4 During weighing, the lifting component 11 moves the pallet 51 upward to the weighing position. The pallet 51 then moves the support plate 53 and the weighing plate 52 upward. The upper surface of the weighing plate 52 directly abuts against the lower end of the anti-detachment plate 42, lifting the anti-detachment plate 42 upward to the preset distance in the initial state. The outer circumference of the positioning ring 41 is completely separated from the inner wall of the positioning hole 4. The basket 43 and the fruit are only supported on the positioning ring 41, thus completing the vibration isolation from the conveyor belt 2. The entire weight of the fruit and the positioning ring 41 is transferred to the weighing plate 52 and the weight sensor 54 through the anti-detachment plate 42, completing the collection of weight data.

[0036] Reference Figure 2 and Figure 4 The outer circle of the anti-detachment plate 42 is set as an arc surface, and both ends of the weighing plate 52 along the length direction are set as arc surfaces. When the weighing plate 52 and the anti-detachment plate 42 come into contact, the arc surfaces guide the contact between the two, reducing the probability of damage caused by hard contact.

[0037] Reference Figure 2 and Figure 4 To reduce fruit damage, a flexible pad 44 is glued to the end of the positioning ring 41 away from the anti-detachment plate 42, that is, the end facing the upper surface of the conveyor belt 2. The flexible pad 44 is in contact with the inner wall of the positioning ring 41. When the fruit falls into the basket 43 or shakes due to conveying, the flexible pad 44 forms a secondary buffer to prevent the fruit skin from directly colliding with the relatively hard positioning ring 41.

[0038] Reference Figure 1 and Figure 5The feeding platform 3 includes an independently driven conveyor belt 31 and several diverter plates 32. The conveyor belt 31 is located at the feeding end of the conveyor belt 2. The multiple diverter plates 32 are distributed along the width direction of the upper surface of the conveyor belt 31, and a conveying trough 33 extending along the conveying direction is defined between two adjacent diverter plates 32. The number of these conveying troughs 33 is consistent with the number of positioning holes 4 opened on a chain plate, so that each conveying trough 33 can correspond to a subsequent weighing station, realizing the single-channel orderly feeding of fruits.

[0039] Reference Figure 1 and Figure 5 To control the feeding cycle, a baffle 34 is vertically slidably connected to the frame 1 at the unloading end of the conveyor belt 31. The baffle 34 has a blocking position and a releasing position. When it is in the blocking position, the surface of the baffle 34 lies across the moving path of the fruit, preventing the fruit from entering the conveyor belt 2. A lifting component 35 is installed on the frame 1. The output end of the lifting component 35 is connected to the baffle 34 to drive the baffle 34 to slide vertically to achieve position switching.

[0040] Reference Figure 1 and Figure 5 For intuitive indication of weighing results, the conveyor belt 2 is equipped with multi-color indicator lights 21 corresponding to each positioning hole 4. Each multi-color indicator light 21 is electrically connected to the weight sensor 54 at the corresponding workstation. After the weight sensor 54 completes the weighing, it illuminates the light of the corresponding color according to the range of the measured weight value, providing on-site personnel with a quick classification identification signal.

[0041] Reference Figure 1 and Figure 5 In the feeding section, a rolling belt 6 is installed across the frame 1 above the conveyor belt 31. The outer surface of the rolling belt 6 is evenly covered with soft bristles 61. Simultaneously, pressure sensors 12 are installed along the width of the inner side of the conveyor belt 31, corresponding to the lower part of each conveying trough 33. Each pressure sensor 12 corresponds one-to-one with each conveying trough 33. When the rolling belt 6 rotates, it drives the soft bristles 61 to gently brush the surface of the passing fruit, while each pressure sensor 12 monitors the passage of fruit in its corresponding conveying trough 33 in real time, providing the system with material monitoring signals for each channel.

[0042] Reference Figure 1 and Figure 5In addition, along the width of the frame 1, a long strip of indicator light 13 is installed at each of the two edges corresponding to each conveying trough 33. Each indicator light 13 is electrically connected to a pressure sensor 12 at the same location. When the pressure sensor 12 in a certain conveying trough 33 detects that fruit is continuously passing through, it will drive the indicator light 13 corresponding to that trough to dynamically display with varying length or brightness. The operator can quickly grasp the material flow of each channel by observing the status of the light strip from a distance.

[0043] The implementation principle of the online dynamic weighing conveyor device for fruits in this application embodiment is as follows: The fruits to be weighed are divided into corresponding channels by the conveyor belt 31 of the feeding platform 3 via the diverter plate 32, and enter the corresponding positioning rings 41 on the conveyor belt 2 in batches under the intermittent control of the baffle 34, falling into the basket 43. The conveyor belt 2 carries the positioning rings 41 and fruits forward. When it reaches the weighing station, the lifting component 11 drives the pallet 51 to rise. The pallet 51 drives the support plate 53 and the weighing plate 52 to rise. The weighing plate 52 lifts the anti-detachment plate 42 a preset distance, causing the positioning rings 41 to disengage from the inner wall of the positioning hole 4 of the conveyor belt 2, blocking the transmission of vibration from the conveyor belt 2 to the weighing component. At this time, the load on the weighing frame is accurately measured by the weight sensor 54, and the weight grade is displayed in real time by the multi-color indicator light 21. After weighing is completed, the lifting component 11 is reset, the positioning rings 41 fall back into the positioning hole 4, and the fruits continue to move forward with the conveyor belt 2 to enter the subsequent grading process. This structure enables dynamic and precise weighing of fruits during continuous transport.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
