[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention proposes an apple sorting and bagging device. The device enables apples to move in a sorting cylinder through a spiral conveyor. Through fruit leakage grooves of different widths on the sorting cylinder, dynamic screening is achieved by utilizing the size difference of the apples themselves, that is, smaller apples preferentially fall from the front narrow groove, and larger apples are gradually discharged from the rear wide groove as the conveying process proceeds, thereby forming a natural sorting flow. This replaces manual use of card sleeves to screen apples, thereby improving apple sorting efficiency and reducing apple sorting costs. The sorted apples are packaged through a packaging assembly connected to the sorting groove, so that the apples can directly enter the bagging link after being sorted, thereby avoiding collision damage caused by secondary handling, thereby ensuring fruit quality and reducing labor costs.

[0016] Furthermore, the packaging component in the device forms a linear conveying channel through the seamless connection of the sorting flow channel and the sorting trough. After sorting, the apples directly enter the packaging bag preset by the diversion opening ring, without the need for manual stacking, thereby improving the packaging efficiency. At the same time, the coordinated use of the diversion opening ring, the heat sealing component and the vertical sealing shearing component can quickly package the screened apples, realizing the integrated processing from apple screening to packaging, shortening the apple screening and packaging time, and improving the efficiency of apple sorting and packaging.

[0017] Furthermore, after the fruit transport component in the device buffers the apples in the fruit bin, the conveyor belt lifts them steadily to the fruit guide bucket, and the transport volume can be adjusted according to the sorting rhythm, which not only avoids fruit flow congestion caused by manual dumping, but also eliminates the efficiency window period caused by frequent adding of materials, reducing the workload of the handling personnel.

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] The present invention provides an apple sorting and bagging device. As Figures 1 to 11 shown, it includes a sorting component 1, and on one side of the sorting component 1, there is a packing component for packing the sorted apples. As Figure 1 and Figure 2 shown, the sorting component 1 includes a sorting box 101. Inside the sorting box 101, a classification cylinder 106 is horizontally installed near the top port. At the position of the other end of the classification cylinder 106 on the sorting box 101, a fruit guide hopper 504 is provided. The fruit guide hopper 504 is used to convey apples. At the positions near the two ends of the classification cylinder 106 inside the classification cylinder 106, there are support plates. On the inner end faces of the support plates, support rings are connected. Between the two support rings, a screw conveyor 102 is rotatably installed. The screw conveyor 102 is concentric with the classification cylinder 106. One end of the screw conveyor 102 away from the fruit guide hopper 504 is connected to a transmission component 8. Through the transmission component 8, the screw conveyor 102 rotates inside the classification cylinder 106, moving the apples from the fruit guide hopper 504 along the axial direction of the classification cylinder 106, that is, the apples move from the fruit guide hopper 504 towards the direction of the transmission component 8.

[0026] As Figure 1 and Figure 3As shown in the figure, leaky fruit grooves are arranged along the axial direction on the outer wall of the sorting cylinder 106, and the leaky fruit grooves penetrate into the interior of the sorting cylinder 106. Moreover, the width of the leaky fruit groove on the sorting cylinder 106 near the fruit guiding hopper 504 is smaller than the width of the leaky fruit groove on the sorting cylinder 106 near the transmission assembly 8. When the apples move from the fruit guiding hopper 504 towards the transmission assembly 8, the smaller apples fall out of the sorting cylinder 106 first through the leaky fruit groove with a smaller width. The larger apples continue to move along the axial direction of the sorting cylinder 106 under the push of the screw conveyor 102. When the position of the apples in the sorting cylinder 106 exceeds the center of the sorting box 101, they fall out through the corresponding leaky fruit groove on the sorting cylinder 106 and drop into the sorting box 101. Sorting grooves 104 are respectively arranged at the positions of the two ends of the sorting box 101 where the sorting cylinder 106 is located. The two sorting grooves 104 are parallel to each other. When the axis of the sorting cylinder 106 and the center line of the sorting groove 104 are both projected onto the bottom end face of the sorting box 101, they are perpendicular to each other. One end port of the sorting groove 104 is attached to one inner wall of the sorting box 101, and the other end port of the sorting groove 104 extends outside the sorting box 101 and is connected to the packing assembly. When the apples are screened by the sorting cylinder 106, they fall into the corresponding sorting groove 104, and then are guided to the outside of the sorting box 101 through the sorting groove 104 and are packed by the packing assembly. This realizes the rapid sorting of apples, improves the apple screening efficiency, and reduces the apple screening cost. The distance from the end port of the sorting groove 104 that extends outside the sorting box 101 to the bottom surface of the sorting box 101 is smaller than the distance from the end port of the sorting groove 104 that does not extend outside the sorting box 101 to the bottom surface of the sorting box 101, that is, the sorting groove 104 is inclined along the direction in which it extends outside the sorting box 101. Through the inclined sorting groove 104, the apples falling into it can move towards the packing assembly under the action of their gravity, avoiding the accumulation of apples in the sorting groove 104 and affecting the sorting of apples, and improving the automation degree of this device.

[0027] Preferably, as Figure 3 shown, a connecting plate is arranged at the central position of the sorting box 101 near the sorting cylinder 106. The connecting plate is located below the sorting cylinder 106, and the projection line of the connecting plate on the sorting box 101 is perpendicular to the projection line of the sorting cylinder 106 on the bottom surface of the sorting box 101. Guide plates are inclinedly installed between the connecting plate and the sorting grooves 104 respectively. The guide plates provide a sliding ramp for the apples screened near the central position in the sorting cylinder 106, and at the same time isolate the apples screened into the two sorting grooves 104 to avoid mutual mixing and affecting the apple screening efficiency.

[0028] As Figure 11As shown in the figure, a cover plate 107 is provided at the top of the sorting box 101. The cover plate 107 is slidably installed on the top of the sorting box 101 to block the top of the sorting box 101, preventing some sundries and the like from entering the sorting box 101 during the apple screening process and damaging the apples in the sorting box 101. At the same time, during the apple screening process, damaged apples can be taken out from the sorting slot 104 by sliding the cover plate 107. In this embodiment, the cover plate 107 is an acrylic plate.

[0029] As Figure 10 As shown in the figure, the transmission assembly 8 includes a support base. The support base is fixed to the bottom of the sorting box 101 to support the sorting box 101 and at the same time provide an installation space for other components. A first motor 801 is installed at a position below the sorting box 101 on the support base. The output shaft of the first motor 801 is parallel to the axial direction of the screw conveyor 102. A reducer 802 is connected to the output shaft of the first motor 801. A first large pulley 803 is connected to the output shaft of the reducer 802. A first small pulley 805 is connected to the screw conveyor 102. The first large pulley 803 and the first small pulley 805 are arranged in parallel, and a first transmission belt 804 is connected between the first large pulley 803 and the first small pulley 805. Through the first transmission belt 804, the first large pulley 803 and the first small pulley 805 rotate synchronously, and then the screw conveyor 102 rotates stably.

[0030] As Figures 3 to 9As shown in the figure, the packing component includes a sorting channel 103. One end of the sorting channel 103 is connected to the end extending outside the sorting box 101 on the sorting trough 104. A diversion opening ring 105 is arranged on the sorting channel 103. A rotating shaft is vertically arranged in the sorting box 101, and a turntable is arranged on the rotating shaft. The rotating shaft is used for winding and unwinding a single-layer packaging bag 6. When used for the first time, the single-layer packaging bag 6 is manually pulled and placed into the diversion opening ring 105 for clamping; on the side of the diversion opening ring 105 at the opening position, a heat-sealing component 3 is arranged; the heat-sealing component 3 is installed on a support seat. The heat-sealing component 3 includes a mounting frame fixed on the support seat. On the upper end face of the mounting frame, a third motor 301 is connected. The output shaft of the third motor 301 is vertically upward. On the output shaft of the third motor 301, a rotating disk 303 is connected. On the upper end face of the rotating disk 303, at a position near its side, a connecting column is arranged. One end of a first connecting rod 304 is rotatably connected to the connecting column. On the first connecting rod 304, at the end far from the connecting column, a push rod 305 is connected. The push rod 305 is horizontally installed in the mounting frame and slides horizontally in the mounting frame. At the end of the push rod 305 far from the first connecting rod 304, a heat sealer 306 is horizontally arranged. The heat sealer 306 is aligned with the opening position on the diversion opening ring 105. When the packaging bag 6 is clamped in the diversion opening ring 105, the rotating disk 303 is rotated by the third motor 301. The rotating disk 303 pushes the first connecting rod 304 and the push rod 305, so that the heat sealer 306 moves and fits against the opening of the packaging bag 6 to heat-seal the side of the packaging bag 6, making the packaging bag 6 form a cylinder shape.

[0031] Preferably, as Figure 5 shown, a fruit blocking component 2 is arranged between the inlet of the sorting channel 103 and the outlet of the sorting trough 104. The fruit blocking component 2 includes a mounting plate horizontally fixed on the outer wall of the support seat. On the upper end face of the mounting plate, a fourth motor 202 is arranged. One end of a second crank 201 is connected to the output shaft of the fourth motor 202. The other end of the second crank 201 is rotatably connected to a second connecting rod 203. The other end of the second connecting rod 203, far from the second crank 201, is rotatably connected to a baffle 204. The baffle 204 is slidably installed between the inlet of the sorting channel 103 and the outlet of the sorting trough 104. And on the outer wall of the sorting box 101, at positions corresponding to the outlet of the sorting trough 104, limiting platforms are symmetrically arranged. The baffle 204 is installed between the limiting platforms.

[0032] As Figure 1 、 Figure 7 and Figure 8As shown, a vertical sealing and cutting assembly 4 is provided at the other end of the sorting channel 103. The port of the tubular packaging bag 6 is placed in the vertical sealing and cutting assembly 4 for heat sealing, so as to heat seal the bottom of the tubular packaging bag 6. After the apples slide through the sorting channel 103 into the heat-sealed packaging bag 6, the vertical sealing and cutting assembly 4 is used again to heat seal and cut at the top of the apples, completing the packaging of the apples; As Figure 7 and Figure 8 shown, the vertical sealing and cutting assembly 4 includes a mounting seat. Two groups of first cranks 406 are symmetrically arranged for rotation inside the mounting seat. Each group of first cranks 406 includes two first cranks 406. A connecting frame is installed between the two first cranks 406 inside each group of first cranks 406. A sealing and cutting device 405 is arranged on one side end face of the connecting frame. Transmission rods are connected to both groups of first cranks 406, and a driving part is connected to the transmission rods; when the packaging bag 6 is located between the two connecting frames, the two connecting frames are rotated through the driving part, so that the two sealing and cutting devices 405 are brought into contact to seal or cut the packaging bag 6.

[0033] As Figure 7 and Figure 8 shown, the driving part includes a gear set. The gear set includes two first gears 401. The two first gears 401 mesh with each other and are rotatably installed on the outer wall of the mounting seat. A second large pulley 403 is connected to the first gear 401. A second small pulley 404 is connected to the transmission rod. The second large pulley 403 and the second small pulley 404 are installed vertically aligned. A second transmission belt 408 is connected between the second large pulley 403 and the second small pulley 404. Through the second transmission belt 408, the second large pulley 403 and the second small pulley 404 are synchronously rotated, so that the two connecting frames are synchronously rotated, and the rotation directions of the two connecting frames are opposite; a second gear 402 is connected to one of the first gears 401 in the gear set. The second gear 402 meshes with the first gear 401. A second motor 407 is connected to the second gear 402. Through the second motor 407, the second gear 402 is rotated, and then the power is transmitted to the first gear 401. The first gear 401 makes the first crank 406 rotate through the cooperation of the second large pulley 403, the second transmission belt 408 and the second small pulley 404, so that the connecting frame rotates.

[0034] As Figure 1 and Figure 9As shown in the figure, a transportation component 7 is provided at the bottom of the vertical sealing and shearing component 4. The transportation component 7 includes a conveyor belt 703 and a conveyor frame. Two rollers are arranged in parallel on the conveyor frame.

One end of the conveyor belt 703 is located below the sealing and shearing cutter 405, and a packing box 702 is provided below the other end of the conveyor belt 703. A mover 701 is provided at the bottom of the packing box 702, and the mover 701 is a flatbed trolley.

[0035] As Figure 1 and Figure 2 As shown in the figure, a fruit conveying component 5 is provided on the side of the fruit guiding hopper 504. The fruit conveying component 5 includes a support frame. Two driving rollers 503 are symmetrically and parallelly installed on the support frame. A second driving motor is connected to one of the driving rollers 503, and a conveyor belt 501 is connected between the two driving rollers 503. A fruit blocking plate is provided on the conveyor belt 501 to prevent the apples from moving or rolling along the moving direction of the conveyor belt 501 during the conveying process, which may cause damage to the apples. The upper end of the conveyor belt 501 is close to the fruit guiding hopper 504, and a fruit storage bin 502 is provided at the position of the lower end of the conveyor belt 501 on the support frame. The apples are contained in the fruit storage bin 502 and then conveyed into the fruit guiding hopper 504 through the conveyor belt 501 for screening and packaging.

[0036] A controller is provided on the sorting box 101 of this device. The controller is used to control the start of the first motor 801, the second motor 407, the third motor 301 and the fourth motor 202, so as to realize different process controls. Protective cotton is provided on the channels of apple screening and packaging in this device, that is, protective cotton is provided on the inner walls of the fruit guiding hopper 504, the fruit blocking plate, the fruit storage bin 502, the conveyor belt 501, the sorting box 101, the inner wall of the sorting channel 101, the inner wall of the sorting groove 104, the inner wall of the sorting cylinder 106, and the inner wall of the packing box 702.

[0037] The present invention provides a method for using an apple sorting and bagging device, which is used for the above-mentioned apple sorting and bagging device, and includes the following steps: Put the apples into the fruit guiding hopper 504; Start the transmission component 8, and the apples in the fruit guiding hopper 504 are conveyed through the screw conveyor 102 in the sorting cylinder 106 in the sorting component 1, so that the apples move along the axis of the sorting cylinder 106; During the moving process, the smaller apples fall from the fruit leakage groove close to the fruit guiding hopper 504 into the corresponding sorting groove 104, and the larger apples fall from the fruit leakage groove close to the transmission component 8 into the corresponding sorting groove 104; The apples move out of the sorting box 101 along the sorting chute 104 and are packaged by a packaging component connected to the port where the sorting chute 104 extends out of the sorting box 101.

[0038] Specifically, before using this device, the single-layer packaging bag 6 must be manually pulled from the gap of the diversion opening ring 105 along the sorting channel 103 to the vertical sealing and shearing component 4. The side of the packaging bag 6 is located at the opening of the diversion opening ring 105 and is heat-sealed by the heat-sealing component 3. That is, under the action of the third motor 301, the transmission shaft 302 rotates, the transmission shaft 302 drives the rotating disk 303 to rotate, and then the rotating disk 303 drives the first connecting rod 304 to move. The heat-sealer 306 is pushed towards the opening of the diversion opening ring 105 through the push rod 305 to heat-seal the side of the packaging bag 6.

[0039] The bottom of the packaging bag 6 starts vertical sealing and shearing under the action of the vertical sealing and shearing component 4. That is, the output shaft of the second motor 407 drives the second gear 402 to rotate. Through the meshing of the second gear 402 with the first gear 401, and then through the cooperation of the second large pulley 403, the second transmission belt 408 and the second small pulley 404, the first crank 406 moves. Under the action of the first crank 406, the two sealing and shearing cutters 405 converge to achieve the vertical sealing of the bottom of the packaging bag 6 and complete the three-sided heat-sealing of the packaging bag 6.

[0040] Start the second drive motor, put the apples into the fruit storage bin 502, and convey the apples into the fruit guiding hopper 504 through the cooperation of the conveyor belt 501 and the driving roller 503; Start the transmission component 8, that is, start the first motor 801. The first motor 801 drives the reducer 802 to work, the reducer 802 drives the first large pulley 803 to rotate, the first large pulley 803 drives the first small pulley 805 to rotate through the first transmission belt 804, and the first small pulley 805 drives the screw conveyor 102 to rotate, gradually input the apples in the fruit guiding hopper 504 into the import classification cylinder 106, and move along the classification cylinder 106. The apples in the import classification cylinder 106 are screened through the fruit leakage groove, so that apples of the same size fall into the corresponding sorting chute 104 in the sorting box 101, and then flow into the corresponding sorting channel 103, completing the screening of the apples. The screened apples roll along the sorting channel 103 into the packaging bag 6 provided at its port. The fourth motor 202 is started, so that the baffle 204 is clamped at the connection position between the sorting channel 103 and the sorting chute 104 to prevent the apples from continuing to fall.
