Description

Technical Field

[0001] This invention patent relates to the technical field of fruit weighing. Specifically, it relates to intelligent fruit weighing equipment. Background Art

[0002] With the continuous development of China's economy, the living standards of the people have been significantly improved. The fruit business is constantly changing from a quantity-based model to a quality-based model. It is gradually difficult for small vendors and traditional fruit stores to meet the requirements of the vast number of consumers for fruit quality and purchasing environment. Therefore, fruit chain supermarkets can gain market recognition and are an inevitable choice for the development of fruit sales.

[0003] Currently, fruit weighing in supermarkets is divided into two major steps. The first step is to weigh the fruit on the weighing platform and print barcodes. The second step is that the weighed fruit needs to be packed by another packing machine.

[0004] In the prior art, manual weighing and packing are adopted. Employees need to memorize the serial numbers corresponding to fruits and barcodes. Otherwise, it is easy to lead to low weighing efficiency and long waiting times for customers in line. At the same time, multiple employees need to take turns on duty, resulting in high labor costs. Summary of the Invention

[0005] The purpose of the present invention is to provide intelligent fruit weighing equipment, aiming to solve the problem of high labor costs in fruit weighing in the prior art.

[0006] The present invention is implemented as follows. The intelligent fruit weighing equipment includes a buffer recognition structure, a weighing structure, and a packing structure. The buffer recognition structure, the weighing structure, and the packing structure are arranged in corresponding order. The buffer recognition structure includes at least one buffer tray for placing fruits. The buffer tray transports the fruits to the weighing structure. The weighing structure weighs the fruits and then transports them to the packing structure. The packing structure packs and seals the fruits.

[0007] Furthermore, the buffer recognition structure includes multiple buffer trays, a rotating disk, a lifting member, and an identification camera. The identification camera is used to extract fruit images, and the background analyzes and identifies the fruit types based on algorithms. Each buffer tray is provided with the rotating disk, and the rotating disk rotates in a circular motion to adjust the position of the buffer tray. The inner end of the buffer tray is hinged to the rotating disk, and the lifting member is connected to the outer end of the buffer tray. The lifting member rises or falls to adjust the inclination angle of the buffer tray. When the lifting member rises, the fruits on the buffer tray fall into the weighing structure.

[0008] Further, the lifting member includes a lifting motor, a lifting plate and a lifting rod. The upper part of the lifting rod is connected to the lifting plate, and the lower part of the lifting rod is connected to the lifting motor. The lifting motor drives the lifting rod to move up or down, driving the lifting plate to move up or down. The lifting plate has a lifting surface, and the rotating disk is arranged corresponding to the lifting surface up and down.

[0009] Further, the weighing structure includes a weighing pan, a weighing module, a placing plate and a transfer member. The placing plate is arranged horizontally and has an adjustment opening. The weighing module is used for weighing, and the placing plate is in contact with the weighing module up and down. The weighing pan is arranged corresponding to the placing plate up and down. The placing plate is provided with a hinge joint and a support platform. The hinge joint and the support platform extend towards the weighing pan respectively. One end of the weighing pan is hinged to the placing plate through the hinge joint, and the other end of the weighing pan is movably arranged. When weighing, the other end of the weighing pan abuts against the support platform. The transfer member moves up or down. When the fruit weighing is completed, the transfer member moves up and abuts against the weighing pan through the adjustment opening, causing the other end of the weighing pan to gradually face upwards until the fruit falls into the packing structure.

[0010] Further, the transfer member includes a transfer motor, a transfer rod and a transfer block. The upper part of the transfer rod is connected to the transfer block, and the lower part of the transfer rod is connected to the transfer motor. The transfer motor drives the transfer rod to move up or down, driving the transfer block to move up or down. The transfer block has a transfer surface which is inclined. When transferring the fruit, the transfer block passes through the adjustment opening, and the transfer surface abuts against the weighing pan.

[0011] Further, the packing structure includes a feeding mechanism, a sealing mechanism and an opening mechanism. The feeding mechanism is used for conveying packing bags. The sealing mechanism is used for heat-sealing the packing bags, and the opening mechanism is used for opening the packing bags to let the fruit fall in. When performing the packing operation, the feeding mechanism conveys the packing bags to the sealing mechanism. The sealing mechanism performs primary heat-sealing on the packing bags. After heat-sealing, the packing bags are continuously conveyed. The opening mechanism opens the packing bags to let the fruit fall in, and then the sealing mechanism performs secondary heat-sealing on the packing bags.

[0012] Further, the packing structure includes a packing board, and the feeding mechanism transports the packing bag to the packing board; the packaging mechanism includes a packaging motor, a packaging shaft, a lower pressing plate and a heat sealer. The lower part of the packaging shaft is connected to the lower pressing plate, and the upper part of the packaging shaft is connected to the packaging motor.

[0013] Further, the packing board includes an upper board and a lower board. The upper board is arranged obliquely. The inner end of the lower board faces the upper board, and the outer end of the lower board is inclined upwards. During heat sealing operation, the feeding mechanism transports the packing bag along the upper board towards the lower board; two guiding plates are provided on the upper board. The guiding plates protrude upwards along the direction away from the upper board, and along the direction away from the lower board, the two guiding plates are arranged in a flared shape.

[0014] Further, the opening mechanism includes at least one upper suction cup and at least one lower suction cup. The lower suction cup is installed on the upper board, and the upper suction cup is installed on the lower pressing plate; when opening the packing bag, the upper suction cup and the lower suction cup correspondingly adsorb the packing bag, and the lower pressing plate drives the upper suction cup to move along the direction away from the lower suction cup to open the packing bag.

[0015] Further, the packing structure includes a bag cutting mechanism, and the bag cutting mechanism is located below the upper board; the upper board has a cutting groove, and the bag cutting mechanism includes a cutting knife and a bag cutting motor. The bag cutting motor is used to drive the cutting knife to move towards or away from the cutting groove; the cutting knife cuts the packing bag through the cutting groove.

[0016] Compared with the prior art, for the intelligent fruit weighing device provided by the present invention, a customer places fruits on the cache recognition structure, and the cache recognition structure recognizes the corresponding fruits. After recognition, the fruits are transferred to the weighing structure. The weighing structure weighs the fruits based on the recognized fruit types.

This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the accompanying drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0033] Referring Figures 1 - 13 as shown, it is a preferred embodiment provided by the present invention.

[0034] The intelligent fruit weighing device includes a cache recognition structure 1, a weighing structure 2, and a packing structure 3. The cache recognition structure 1, the weighing structure 2, and the packing structure 3 are arranged in sequence correspondingly; the cache recognition structure 1 includes at least one cache tray 12. The cache tray 12 is used to place fruits, and the cache tray 12 transports the fruits to the weighing structure 2. After the weighing structure 2 weighs the fruits, it transports them to the packing structure 3, and the packing structure 3 packs and seals the fruits.

[0035] For the above intelligent fruit weighing device, customers place the fruits on the cache recognition structure 1. The cache recognition structure 1 recognizes the corresponding fruits. After recognition, the fruits are transported to the weighing structure 2. The weighing structure 2 weighs the fruits based on the recognized fruit types. After the fruits are weighed, they are transported from the weighing structure 2 to the packing structure 3, and the packing structure 3 packs and seals the fruits. In this way, in an automated manner, automatic recognition, weighing, and packing of fruits are realized, avoiding long queues for customers and wasting time. At the same time, the dependence on labor is reduced, the labor input is reduced, and the labor cost is greatly reduced.

[0036] The intelligent fruit weighing device includes a control board. The control board is preset with a control program. The control board is electrically connected to the cache recognition structure 1, the weighing structure 2, and the packing structure 3 respectively to realize the control of the cache recognition structure 1, the weighing structure 2, and the packing structure 3.

[0037] An Arduino 2560 controller is used as the control board. This control board can provide nearly 70 ports at most, enabling program control of all motors, servos, sensors, switches, buttons, and indicator lights.

[0038] The cache recognition structure 1 includes a plurality of cache trays 12, a rotating disk 13, a lifting member 14, and an identification camera 11. The identification camera 11 is used to extract fruit images, and the background analyzes and identifies the fruit types based on algorithms; realizing the identification of fruit types is convenient for the subsequent weighing structure 2 to perform corresponding weighing.

[0039] Each buffer tray 12 is provided with a rotating tray 13, and the rotating tray 13 rotates in a circular motion to adjust the position of the buffer tray 12; different customers place fruits on different buffer trays 12 respectively, which improves the compactness of the whole process and the efficiency of the equipment. At the same time, it avoids the fruits being held by customers and improves the customer experience.

[0040] The buffer identification structure 1 includes a rotating motor 16 which has a rotating gear, and the rotating gear is arranged in meshing with the rotating tray 13; in this way, by driving the rotating gear to rotate through the rotating motor 16, the rotating tray 13 is driven to rotate in a circular motion, so as to realize the position adjustment of the buffer tray 12.

[0041] Each buffer tray 12 is arranged in a circle along the center of the rotating tray 13. In this way, by rotating the rotating tray 13, the switching of the buffer trays is realized; at the same time, under the action of centrifugal force, it is convenient for the fruits in the buffer tray 12 to tend to one end, which is convenient for transferring the fruits from the buffer tray 12 to the weighing structure 2 subsequently.

[0042] The inner end of the buffer tray 12 is hinged to the rotating tray 13, and the lifting member 14 is connected to the outer end of the buffer tray 12; the lifting member 14 rises or falls to adjust the inclination angle of the buffer tray 12; when the lifting member 14 rises, the fruits in the buffer tray 12 fall into the weighing structure 2; in this way, when the equipment starts to work, the control member, based on the identification camera 11, judges whether there are fruits placed on the buffer tray 12 and analyzes and identifies the fruit types. After determination, the control member controls the lifting member 14 to rise, so that the buffer tray 12 is arranged obliquely. Under the action of gravity, the water falls into the weighing structure 2, and the weighing structure 2 weighs correspondingly based on the identified fruit types.

[0043] The inner end of the buffer tray 12 is hinged to the rotating tray 13 through a hinge portion 15. In this way, when transferring fruits, the outer end of the buffer tray 12 is arranged obliquely upward or horizontally along the hinge portion 15.

[0044] The lifting member 14 includes a lifting motor 141, a lifting plate 143 and a lifting rod 142. The upper part of the lifting rod 142 is connected to the lifting plate 143, and the lower part of the lifting rod 142 is connected to the lifting motor 141; the lifting motor 141 drives the lifting rod 142 to rise or fall, driving the lifting plate 143 to rise or fall; the lifting plate 143 has a lifting surface, and the rotating tray 13 is arranged corresponding to the lifting surface up and down; in this way, the rotating tray 13 is switched between a horizontal state and an inclined state.

[0045] The lifting member 14 is fixedly arranged. When the buffer tray 12 moves to be correspondingly arranged with the weighing tray 21, at this time, the outer end of the buffer tray is arranged corresponding to the lifting member 14 up and down. In this way, the rising or falling of the lifting member 14 realizes the switching of the rotating tray 13 between a horizontal state and an inclined state.

[0046] The buffer tray 12 includes a buffer bottom plate and buffer side plates. The buffer bottom plate is horizontally arranged, and the buffer side plates are inclined. The buffer side plates are close to the weighing structure 2. The inner ends of the buffer side plates are connected to the buffer bottom plate, and the outer ends of the buffer side plates are gradually inclined upward in a direction away from the buffer bottom plate. In this way, it is convenient for fruits to be placed in the buffer tray 12, and during the buffering process, the buffer side plates play a limiting role to prevent the fruits from falling out of the buffer tray 12. When transferring the fruits, the buffer side plates are in contact with the weighing tray 21, playing a guiding role to facilitate the fruits to fall into the weighing tray 21.

[0047] The buffer side plates are provided with two buffer plates, which are arranged correspondingly. Along the direction away from the buffer bottom plate, the two buffer plates are gradually inclined towards each other. When the fruits are transferred from the buffer tray 12 to the weighing tray 21, the two buffer plates play a role of buffering and decelerating, and also prompt the fruits to tend to the middle, facilitating the fruits to fall into the weighing tray 21.

[0048] The fruit recognition scheme adopts the simultaneous recognition of the shape, size and color of the fruits. The Openmv camera is selected as the main recognition component. Visual recognition has relatively high requirements for environmental stability. For example, the recognition background should have a large color difference from the recognized object, and the environmental light source brightness should be stable, etc.

[0049] Before performing image shape recognition, Openmv needs to preprocess the captured fruits, including grayscale conversion and enhancement of the color image.

[0050] Since the threshold selection needs to refer to the histogram, after the image is processed, the histogram of the image is obtained to help select the threshold.

[0051] The whole process is called binarizing the image. The corresponding gray value T is selected as the threshold value at the most suitable valley point of the histogram of the image. Let u(i, j) be the gray value of the binarized image at the scanned point, then

[0052]

[0053] After the above binarization algorithm, the gray level of the fruits is all 1, and the gray value of the background is all 0, so as to obtain the image of the fruit shape.

[0054] The weighing structure 2 includes a weighing tray 21, a weighing module 23, a placement plate 22 and a transfer member 24. The placement plate 22 is horizontally arranged and has an adjustment opening. The weighing module 23 is used for weighing, and the placement plate 22 and the weighing module 23 are arranged in an up-and-down contact manner. In this way, during weighing, the placement plate 22 and the weighing tray 21 are integrated, and the fruits on the weighing tray 21 are weighed by the weighing module 23.

[0055] Furthermore, the weighing plate 21 and the placement plate 22 are arranged vertically corresponding to each other. The placement plate 22 is provided with a hinge joint 25 and a support platform 26. The hinge joint 25 and the support platform 26 extend towards the weighing plate 21 respectively. One end of the weighing plate 21 is hinged to the placement plate 22 through the hinge joint 25, and the other end of the weighing plate 21 is movably arranged.

[0056] The transfer member 24 is arranged to rise or fall, realizing the angle adjustment of the weighing plate 21.

[0057] During weighing, the other end of the weighing plate 21 abuts against the support platform 26. At this time, the weighing plate 21 is horizontally arranged, which is convenient for weighing fruits and helps to ensure the weighing accuracy. When the fruits are weighed and need to be transferred, the transfer member 24 rises and abuts against the weighing plate 21 through the adjustment opening, making the other end of the weighing plate 21 gradually face upwards, so that the weighing plate 21 is inclined. Under the action of gravity, the fruits fall into the packing structure 3, realizing the transfer of the fruits.

[0058] In addition, under the action of the support platform 26 and in cooperation with the hinge joint 25, it is ensured that the weighing plate 21 is horizontally arranged, improving the weighing accuracy.

[0059] The weighing structure 2 includes two weighing modules 23. The two weighing modules 23 are arranged at intervals corresponding to each other, and the two weighing modules 23 are correspondingly arranged below the weighing plate 21; this avoids offset weighing and improves the weighing accuracy.

[0060] The transfer member 24 includes a transfer motor, a transfer rod and a transfer block. The upper part of the transfer rod is connected to the transfer block, and the lower part of the transfer rod is connected to the transfer motor. The transfer motor drives the transfer rod to rise or fall, driving the transfer block to rise or fall; the transfer block has a transfer surface, and the transfer surface is inclined. When transferring fruits, the transfer block passes through the adjustment opening, and the transfer surface abuts against the weighing plate 21; in this way, the other end of the weighing plate 21 is lifted by the transfer surface of the transfer block.

[0061] The packing structure 3 includes a feeding mechanism 31, a sealing mechanism 32 and an opening mechanism 33. The feeding mechanism 31 is used for conveying packing bags; the sealing mechanism 32 is used for heat-sealing the packing bags, and the opening mechanism 33 is used for opening the packing bags to let the fruits fall in; when carrying out the packing operation, the feeding mechanism 31 conveys the packing bags to the sealing mechanism 32, and the sealing mechanism 32 performs primary heat-sealing on the packing bags. After heat-sealing, the packing bags are continuously conveyed for a certain distance, and the opening mechanism 33 opens the packing bags to let the fruits fall in, and then the sealing mechanism 32 performs secondary heat-sealing on the packing bags; realizing the packing and sealing of the fruits.

[0062] The primary heat-sealing and the secondary heat-sealing realize the sealing of both ends of the packing bag.

[0063] The packing bag can be a fresh-keeping bag, which is convenient for heat-sealing and plays a role in keeping the fruits fresh.

[0064] The feeding mechanism 31 includes a material-releasing roller 311, a conveying roller 312 and a feeding motor. The packing bag is wound around the material-releasing roller 311, and the outer end of the packing bag extends and is clamped by the conveying roller 312. The feeding motor drives the conveying roller 312 to rotate to realize the conveyance of the packing bag.

[0065] The conveying roller 312 includes a first roller body and a second roller body. The feeding motor drives the first roller body and the second roller body to rotate respectively, and the first roller body and the second roller body rotate in opposite directions to realize the conveyance of the packing bag.

[0066] The outer surface of the first roller body is wrapped with a friction layer, and the outer surface of the second roller body is wrapped with a friction layer. The packing bag is clamped through the friction layer to facilitate the conveyance of the packing bag.

[0067] The material-releasing roller 311 and the conveying roller 312 are arranged in a staggered manner. The packing bag extends forward through the conveying roller 312 and then is placed around the packing plate 35 circuitously, increasing the conveying path, avoiding blockage, and making the conveyance of the packing bag smoother.

[0068] The packing structure 3 includes a packing plate 35. The feeding mechanism 31 conveys the packing bag to the packing plate 35. Under the action of the packing plate 35, it is convenient to place the packing bag and for subsequent fruits to enter the packing bag.

[0069] The encapsulation mechanism 32 includes an encapsulation motor 321, an encapsulation shaft 322, a lower pressing plate 323 and a heat sealer 34. The lower part of the encapsulation shaft 322 is connected to the lower pressing plate 323, and the upper part of the encapsulation shaft 322 is connected to the encapsulation motor 321. The encapsulation motor 321 drives the lower pressing plate 323 to move towards or away from the packing plate 35. During heat sealing, the lower pressing plate 323 presses down the packing bag to fix the packing bag, and then the heat sealer 34 is started to perform heat sealing on the packing bag.

[0070] The packing bag stops being conveyed after being conveyed to the heat sealing tape by the feeding mechanism 31. The lower pressing plate 323 is pressed down by driving the screw rod to rotate through a stepping motor. After pressing down in place, the heat sealer 34 is started. After the heat sealer 34 seals the bag opening, the packing bag continues to be conveyed forward a certain distance by the feeding mechanism 31. After the lower pressing plate 323 is pressed stably, the cutting knife 371 cuts off the packing bag. At the same time, the packing bag is sucked up and opened by the upper suction cup 331, waiting for the fruits to enter. After the fruits enter the packing bag, it is encapsulated again to complete the packing.

[0071] The heat-sealing machine 34 includes a heat-sealing shell 341 and a heat-sealing member 342. The heat-sealing member 342 is installed inside the heat-sealing shell 341, and the heat of the heat-sealing member 342 is used for heat-sealing the packing bag; the heat-sealing shell 341 is formed with a heat-sealing groove 343, and the heat-sealing groove 343 is arranged in communication with the heat-sealing member 342; in this way, the lower pressing plate 323 has a lower pressing strip. When the lower pressing plate 323 presses down on the packing bag, the lower pressing strip squeezes the packing bag into the heat-sealing groove 343, and the lower pressing strip and the heat-sealing member 342 clamp the packing bag, and then the heat-sealing operation is carried out; to ensure the stability of heat-sealing and enhance the pressing stability of the packing bag.

[0072] The packing board 35 includes an upper board 351 and a lower board 352. The upper board 351 is arranged obliquely, the inner end of the lower board 352 faces the upper board 351, and the outer end of the lower board 352 is obliquely upward. During the heat-sealing operation, the feeding mechanism 31 conveys the packing bag along the upper board 351 towards the lower board 352; under the action of the upper board 351, it is convenient for fruits to fall into the packing bag. Under the action of the lower board 352, it plays a limiting role to avoid the fruits rolling too fast and causing too much pulling of the packing bag. At the same time, the fruits are basically at the junction of the upper board 351 and the lower board 352, avoiding the fruits affecting the packaging of the packing bag.

[0073] The encapsulation mechanism 32 includes an adjustment motor and an adjustment shaft. The adjustment motor is electrically connected to the control board, the adjustment shaft is connected to the adjustment motor, and the adjustment motor is used to drive the adjustment shaft to rise or fall. The upper part of the adjustment shaft is connected to the upper board 351; in this way, by rising or falling of the adjustment shaft, the inclination angle of the upper board 351 is adjusted; in this way, the control board controls the inclination angle of the upper board 351 based on the fruit type identified by the camera and combined with the weighing result of the weighing structure 2. If the fruit type is relatively large, the inclination angle is reduced to avoid the fruit being too heavy and rolling too fast.

[0074] Two guide plates 353 are provided on the upper board 351. The guide plates 353 protrude upward along the direction away from the upper board 351, and the two guide plates 353 are arranged in a flared shape along the direction away from the lower board 352; in this way, it is convenient for the fruits on the weighing pan 21 to enter the upper board 351, and under the action of the two guide plates 353, it is convenient for the fruits to be centered. Since the opening diameter in the middle of the packing bag is the largest, it is convenient for the fruits to enter the packing bag; at the same time, it avoids a large number of fruits entering at one time and plays a role in shunting.

[0075] The opening mechanism 33 includes at least one upper suction cup 331 and at least one lower suction cup 332. The lower suction cup 332 is installed on the upper board 351, and the upper suction cup 331 is installed on the lower pressing plate 323; when opening the packing bag, the upper suction cup 331 and the lower suction cup 332 correspondingly adsorb the packing bag, and the lower pressing plate 323 drives the upper suction cup 331 to move in the direction away from the lower suction cup 332 to open the packing bag; through the cooperation of the upper suction cup 331 and the lower suction cup 332, the opening of the packing bag is realized.

[0076] The packaging structure 3 includes a bag cutting mechanism 37, which is located below the upper plate 351; the upper plate 351 has a cutting groove 354, and the bag cutting mechanism 37 includes a cutter 371 and a bag cutting motor, and the bag cutting motor is used to drive the cutter 371 to move toward or away from the cutting groove 354; the cutter 371 cuts the packaging bag through the cutting groove 354; in this way, the cutting and separation of the packaging bag is achieved through the cutter 371, which makes it convenient for customers to take the packaged packaging bags.

[0077] The bag cutting mechanism 37 includes a cutting motor, a cutting rod 372 and a cutting block 373. The cutting rod 372 is connected to the cutting block 373, and the cutting rod 372 is arranged horizontally. The cutter 371 is installed on the cutting block 373, and the cutter 371 extends upward. The cutting motor drives the cutting block 373 to reciprocate along the direction of the cutting groove 354, driving the cutter 371 to cut the packaging bag.

[0078] The packaging structure 3 includes a storage table 36, which is arranged corresponding to the lower plate 352. The storage table 36 has a storage surface, which is arranged upward and inclined away from the lower plate 352. The packaged packaging bags are transferred to the storage surface for customers to take.

[0079] The storage table 36 is provided with a swing block 361 and a swing motor, and the swing motor drives the swing block 361 to swing up and down; the storage table 36 and the swing block 361 are arranged correspondingly up and down; when the heat sealing is completed, the control panel controls the swing motor to drive the swing block 361 to swing upward, lift the storage table 36, and make the end of the storage table 36 away from the lower plate 352 swing upward to prevent the packaging bag containing the fruit from leaving the storage table 36; in this way, it is convenient for customers to take it from the storage table 36.

[0080] The storage platform 36 has a bending portion 362 away from the lower plate 352, the bending portion 362 is arranged in a flat shape, and the outer end of the bending portion 362 is arranged upwardly in an inclined manner.
