Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a fruit box conveying device and a fruit and vegetable turning machine. Background Technology

[0002] As people pursue a higher quality of life, their demands for fruit quality are gradually increasing, making fruit sorting an important technology. After fruits and vegetables are picked from the orchard, they are collected and placed in fruit crates. For subsequent processes such as sorting and packaging, a conveyor system typically transports stacked fruit crates containing fruits and vegetables to a pre-set workstation for unpacking. Then, a flipping device flips the fruit crates one by one, causing the fruits and vegetables to fall onto a fruit and vegetable conveyor system, which then transports them to downstream workstations. After the fruits and vegetables have been unpacked, another conveyor system transports the crates to a designated location for stacking.

[0003] like Figure 1 As shown, the conveying direction of the conveying unit 301 is perpendicular to the plane of the paper in the view. Currently, when stacking and unstacking fruit boxes 201 at the conveying unit 301, cylinders 302 are installed on both sides of the conveying unit 301. The two cylinders 302 simultaneously compress and fix the fruit boxes 201, and then the lifting mechanism 303 drives the cylinders 302 and the fruit boxes 201 to rise and fall, thereby realizing the stacking and unstacking of fruit boxes 201. However, if the fruit boxes 201 cannot be accurately controlled to reach the preset work position 101, it will have a significant impact on the stacking and unstacking of fruit boxes 201. Utility Model Content

[0004] The present invention aims to provide a fruit box conveying device and a fruit and vegetable turning machine to solve the technical problem in the prior art that fruit boxes are difficult to accurately reach the preset work position during stacking and unstacking.

[0005] The technical problem solved by this utility model embodiment is addressed by the following technical solution: A fruit box conveying device is provided, including a mounting base, a conveying assembly, a fruit box fixing assembly, and a blocking assembly; The conveying assembly, the fruit box fixing assembly, and the blocking assembly are mounted on the mounting base; The fruit box fixing component is provided with a preset station, and the blocking component is located downstream of the preset station along the transmission direction of the conveying component; After the conveying component transports the fruit box to the preset workstation, the blocking component can block the fruit box. The fruit box fixing component is used to fix the fruit box that has reached the preset work position.

[0006] In this embodiment, the mounting base is used to install the conveying component, the fruit box fixing component, and the blocking component. The conveying component transports the fruit boxes, and the fruit box fixing component secures the fruit boxes at preset workstations to achieve stacking and unstacking of the fruit boxes. Since the blocking component is located downstream of the preset workstation, it can block the fruit boxes after they are transported there, ensuring they arrive at the workstation more accurately. This improves the fixing effect of the fruit box fixing component and ensures smooth stacking and unstacking. Furthermore, by setting the blocking component, the consistency of the fruit boxes arriving at the preset workstation is improved as the conveying component continuously transports them, meaning each fruit box arrives at the same position, which facilitates improved accuracy and efficiency of the stacking and unstacking assembly line operation.

[0007] In some embodiments, the conveying assembly includes a rotation drive element and at least two rollers, the rotation drive element and at least one of the rollers being tractively connected to drive the rollers to rotate, and a preset gap being formed between any two adjacent rollers; The blocking component is located below the roller. After the conveying component transports the fruit box to the preset work station, part of the blocking component can pass through the preset gap to block the fruit box.

[0008] In this embodiment, rollers support and transport the fruit boxes. Driven by a rotation drive element, the fruit boxes can be transported to a preset workstation. Since a preset gap can be formed between any two adjacent rollers, the blocking component can be placed below the rollers, thus not affecting the transport of fruits and vegetables and making the overall structure of the fruit box conveying device simpler. When the fruit box is transported to the preset workstation, part of the blocking component can pass through the preset gap to block the fruit box, thereby achieving precise positioning of the fruit box and ensuring that the fruit box accurately arrives at the preset workstation.

[0009] In some embodiments, the blocking assembly includes a first telescopic drive element and a blocking plate, wherein the first telescopic drive element is mounted on the mounting base and located below the roller, and the blocking plate is mounted on the telescopic end of the first telescopic drive element; The first telescopic drive element can drive the barrier plate through the preset gap to block the fruit box.

[0010] In this embodiment, when the first telescopic drive element is located below the roller, it will not affect the roller's transport of the fruit box. The first telescopic drive element can drive the barrier plate through a preset gap to block the fruit box. Since the barrier plate is a plate-like structure, it can smoothly pass through the preset gap under the action of the first telescopic drive element. Furthermore, the width of the preset gap can be set relatively small to ensure that the roller can effectively support the fruit box.

[0011] In some embodiments, the number of the first telescopic drive elements is at least two, and the barrier plate is mounted on the telescopic end of each of the first telescopic drive elements; The blocking assembly also includes an adapter, and the number of the adapters and the first telescopic drive elements are equal and correspond one-to-one; Each of the adapters includes a base and a mounting shaft, the base being mounted on the telescopic end of a corresponding first telescopic drive element; The barrier plate has mounting holes that correspond one-to-one with the mounting shafts, and the barrier plate is mounted on the corresponding mounting shafts through the corresponding mounting holes.

[0012] In this embodiment, by providing at least two first telescopic drive elements, a relatively stable and balanced supporting force can be generated at both ends of the barrier plate. This ensures that the barrier plate passes through or exits the preset gap in a relatively balanced and stable manner. The base of the adapter is used to install on the telescopic end of the corresponding first telescopic drive element, and the barrier plate is mounted on the corresponding mounting shaft through the mounting hole. This arrangement facilitates the installation and replacement of the barrier plate, and also facilitates inspection and maintenance.

[0013] In some embodiments, each of the bases is provided with a slot, and both ends of each mounting shaft are connected to the opposite side walls of the corresponding slot, and the slots of each base are located on the same straight line; The barrier plate is engaged in the slot.

[0014] In this embodiment, the slot is used to accommodate and fix the barrier plate. By providing the slot, the connection strength between the barrier plate and the base can be improved. In addition, the slot also has a positioning function, allowing the mounting shaft to smoothly pass into the mounting hole of the barrier plate.

[0015] In some embodiments, the conveying assembly is connected to the top of the mounting base, the blocking assembly is connected to the bottom of the mounting base, the two fruit box fixing assemblies are connected to both ends of the mounting base, and the preset workstation is located between the two fruit box fixing assemblies.

[0016] In this embodiment, the blocking component and the conveying component are configured in such a way that they can effectively avoid each other and prevent mutual interference.

[0017] In some embodiments, the fruit box conveying device further includes an adapter plate, one end of which is connected to the bottom end of the mounting base, and the blocking assembly is connected to the other end of the adapter plate.

[0018] In this embodiment, by setting an adapter plate, the blocking component can be positioned directly below the preset gap, allowing the blocking component and the conveying component to further avoid each other and prevent interference. This also ensures that the blocking component can smoothly pass through the preset gap.

[0019] In some embodiments, the fruit box fixing assembly includes a lifting mechanism and a gripping mechanism; The lifting mechanism is mounted on the mounting base; The gripping mechanism includes a mounting frame, a drive unit, a first gripper, and a second gripper. The mounting frame is slidably mounted on the mounting base in a vertical direction. The lifting mechanism is connected to the mounting frame in a transmission manner to drive the mounting frame to move up and down in a vertical direction. One end of the first gripper and one end of the second gripper are respectively hinged to the mounting bracket. The driving unit is connected to the first gripper and the second gripper respectively to drive the other ends of the first gripper and the other ends of the second gripper to move closer or further away from each other. The other end of the first gripper and the other end of the second gripper face the preset work station.

[0020] In this embodiment, the mounting base is used to install the lifting mechanism, which drives the mounting frame to move vertically. When the drive unit drives the other ends of the first and second grippers to move closer together, it can hold the fruit box. When the drive unit drives the other ends of the first and second grippers to move away from each other, it can release the fruit box. When the fruit box is located at a preset work position, the drive unit drives the first and second grippers to hold and release the fruit box, thereby enabling the stacking or unstacking of the fruit box. Because the first and second grippers can hold the fruit box, the force on the fruit box is better, and the gripping force generated by the first and second grippers on the fruit box is relatively small. Therefore, damage to the fruit box can be reduced, and the operating power of the drive unit can also be reduced.

[0021] In some embodiments, the fruit box conveying device further includes sensing components and a controller; The sensing component is mounted on the mounting base and located to the side of the preset workstation; The controller is communicatively connected to the sensing component, the fruit box fixing component, and the barrier component.

[0022] In this embodiment, after the conveying component transports the fruit box to the preset workstation, the sensing component can promptly detect the fruit box. Under the unified control of the controller, the blocking component can promptly block the fruit box, and the fixing component can fix the fruit box.

[0023] This embodiment also provides a fruit and vegetable turning machine, including the above-mentioned fruit box conveying device. The fruit and vegetable turning machine of this embodiment also has the above-mentioned advantages, which will not be repeated here.

[0024] Compared with existing technologies, the fruit box conveying device of this utility model includes a mounting base for installing a conveying component, a fruit box fixing component, and a blocking component. The conveying component transports the fruit boxes, and the fruit box fixing component secures the fruit boxes at preset workstations to achieve stacking and unstacking. Since the blocking component is located downstream of the preset workstation, it blocks the fruit boxes after they are transported there, ensuring they arrive at the workstation more precisely. This improves the fixing effect of the fruit box fixing component and ensures smooth stacking and unstacking. Furthermore, by setting the blocking component, the consistency of fruit boxes arriving at the preset workstation is improved as the conveying component continuously transports them, ensuring that each fruit box arrives at the same position, thus enhancing the accuracy and efficiency of the stacking and unstacking assembly line operation.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0030] Please refer to Figure 2 and Figure 3 One embodiment of this application provides a fruit and vegetable box turning machine 1000, including a depalletizing device 200, a fruit box turning device 300, a fruit and vegetable conveying device (not shown in the figure), a transmission device 400, and a stacking device 500; Along the conveying direction of the fruit box 201, the unloading device 200, the turning device 300, the conveying device 400, and the stacking device 500 are distributed sequentially; as follows: Figure 2 As shown, Figure 2 The direction indicated by the hollow arrow is the transmission direction of the fruit box 201.

[0031] The unloading device 200 is used to transfer the fruit box 201 containing fruits and vegetables to the fruit box flipping device 300. The fruit box flipping device 300 is used to flip the fruit box 201 containing fruits and vegetables. Fruits and vegetables fall from the downstream end of the fruit box flipping device 300 onto the fruit and vegetable conveying device, which is used to collect and transfer the fruits and vegetables in the fruit box 201. The conveying device 400 is used to convey fruit boxes 201 that do not contain fruits and vegetables to the stacking device 500. Stacking device 500 is used to stack fruit boxes 201; The unloading device 200 and the stacking device 500 each include a fruit box conveying device 100.

[0032] In this embodiment, by providing the unpalletizing device 200, fruit boxes 201 containing fruits and vegetables can be smoothly unpalletized. By providing the fruit box flipping device 300, fruit boxes 201 containing fruits and vegetables can be flipped over, preventing damage to the fruits and vegetables. By providing the conveying device 400, fruit boxes 201 without fruits and vegetables can be conveyed to the unpalletizing device 200. By providing the fruit and vegetable conveying device, fruits and vegetables can be conveyed to the downstream workstation. By providing the stacking device 500, fruit boxes 201 without fruits and vegetables can be stacked.

[0033] Specifically, the fruit box tipping device 300 includes a main frame 310, a roller conveyor assembly 320, a first conveyor belt assembly 330, a rotating drum assembly 340, a second conveyor belt assembly, and a telescopic drive assembly 350. The rotating drum assembly 340 is rotatably mounted on the main frame 310. The roller conveyor assembly 320, the first conveyor belt assembly 330, and the telescopic drive assembly 350 are mounted on the rotating drum assembly 340. The roller conveyor assembly 320 and the first conveyor belt assembly 330 are parallel to each other. The telescopic drive assembly 350 is connected to at least one of the roller conveyor assembly 320 and the first conveyor belt assembly 330 to drive the roller conveyor assembly 320 and the first conveyor belt assembly 330 to move closer to or further away from each other. The second conveyor belt assembly is mounted on the main frame 310 and is inclined relative to the horizontal plane. The downstream end of the second conveyor belt assembly is higher than the upstream end of the second conveyor belt assembly. Driven by the rotating drum assembly 340, the downstream end of the first conveyor belt assembly 330 can be flush with the upstream end of the second conveyor belt assembly.

[0034] The main frame 310 is used to mount the rotating drum assembly 340 and the second conveyor belt assembly. The rotating drum assembly 340 can rotate relative to the main frame 310. After the upstream station transfers the fruit box 201 containing fruits and vegetables to the roller conveyor assembly 320, the roller conveyor assembly 320 can continue to transfer the fruit box 201 containing fruits and vegetables a certain distance, so that the fruit box 201 containing fruits and vegetables is transferred between the roller conveyor assembly 320 and the first conveyor belt assembly 330. Under the action of the telescopic drive assembly 350, the roller conveyor assembly 320 and the first conveyor belt assembly 330 can approach each other and clamp the fruit box 201 containing fruits and vegetables. Then, the rotating drum assembly 340 drives the first conveyor belt assembly 330, the roller conveyor assembly 320, and the fruit box 201 containing fruits and vegetables to rotate together, so that the top of the fruit box 201 faces down and the bottom faces up. The fruits and vegetables are transferred from the fruit box 201 to the first conveyor belt assembly 330, and the fruits and vegetables are directly supported on the first conveyor belt assembly 330. The first conveyor belt assembly 330 continues to transport the fruits and vegetables and the rotated fruit box 201 together for a distance. Because the first conveyor belt assembly 330 can support the fruits and vegetables and the rotated fruit box 201, the fruits and vegetables will not fall off, and there will be no damage to the fruits and vegetables during rotation. Under the action of the rotating drum assembly 340, when the downstream end of the first conveyor belt assembly 330 connects with the upstream end of the second conveyor belt assembly, the fruits and vegetables and the rotated fruit box 201 can continue to be transported. The fruits and vegetables fall onto the fruit and vegetable conveying device at the downstream end of the second conveyor belt assembly, and the second conveyor belt assembly continues to transport the rotated fruit box 201 to the conveying device 400.

[0035] The first conveyor belt assembly 330, the second conveyor belt assembly, and the fruit and vegetable conveying device can be belt conveying mechanisms. These mechanisms include a driving pulley, a driven pulley, a belt, and a first motor. The belt is fitted onto the driving pulley and the driven pulley. The first motor is connected to the driving pulley via a transmission drive to drive the driving pulley to rotate, thereby driving the belt and the driven pulley to rotate. Furthermore, the belt conveying mechanism may also include a pressure roller, which is used to tension the belt and control the conveying surface of the belt.

[0036] Downstream of the stacking device 500, fruits and vegetables can be placed again in the stacked fruit boxes 201, and the fruit boxes 201 filled with fruits and vegetables can be transported again to the unstacking device 200.

[0037] Please refer to Figure 4 and Figure 5In some specific embodiments, the transmission device 400 includes a first sprocket 410, a second motor 420, a first chain 430, and a push rod 440; the main frame 310 is provided with a support frame 312, which forms the transmission path of the fruit box 102 and can support the fruit box 102. Specifically, the support frame 312 includes a frame body 3122, an upper limit beam 3124, and a lower limit beam 3126. The upper limit beam 3124 and the lower limit beam 3126 are connected to the frame body 3122. The upper limit beam 3124 abuts against the bottom end of the fruit box 102, and the lower limit beam 3126 abuts against the top end of the fruit box 102. The upper limit beam 3124 and the lower limit beam 3126 jointly support and limit the fruit box 102. A transmission path is formed between the upper limit beam 3124 and the lower limit beam 3126. The upstream end of the transmission path is connected to the downstream end of the first conveyor belt assembly 330, and the downstream end of the transmission path is connected to the stacking device 400. In some embodiments, a belt conveyor mechanism may also be provided between the downstream end of the transmission path and the stacking device 400. Multiple first sprockets 410 are rotatably mounted on opposite sides of the frame body 3122, and first chains 430 are mounted on opposite sides of the frame body 3122. Each first chain 430 is fitted onto the multiple first sprockets 410 on one side of the frame body 3122. A push rod 440 is connected between two first chains 430 and spans the transmission path. A second motor 420 is driven by the first sprockets 410 to drive them to rotate. When the second motor 420 drives the first sprockets 410 to rotate and the first chains 430 are running, the push rod 440 can push the fruit box 102 to move along the transmission path on the support frame 312.

[0038] Preferably, the upstream end of the transmission path is located below the downstream end of the transmission path, and the downstream end of the transmission path is connected to the stacking device 400. That is, the transmission path turns from bottom to top. When the fruit box 102 is transported along the transmission path, the fruit box 102 is flipped over again, so that the top of the fruit box 102 faces upward and the bottom faces downward, and the fruit box 102 is transported to the stacking device 400. Correspondingly, a corresponding first sprocket 410 is provided at the turning node of the frame body 3122, and the upper limit beam 3124 and the lower limit beam 3126 each include arc-shaped segments. Driven by the second motor 420, the fruit box 102 is flipped from bottom to top along the transmission path.

[0039] Please see Figure 4 Another embodiment of this application provides a fruit box conveying device 100, which includes a mounting base 10, a conveying component 20, a fruit box fixing component 30, and a blocking component 40; The conveying assembly 20, the fruit box fixing assembly 30, and the barrier assembly 40 are mounted on the mounting base 10; The fruit box fixing component 30 is provided with a preset station 101, and the blocking component 40 is located downstream of the preset station 101 along the transmission direction of the conveying component 20. After the conveying component 20 transports the fruit box 201 to the preset work station 101, the blocking component 40 can block the fruit box 201. The fruit box fixing component 30 is used to fix the fruit box 201 that has reached the preset work station 101.

[0040] In this embodiment, the mounting base 10 is used to install the conveying assembly 20, the fruit box fixing assembly 30, and the blocking assembly 40. The conveying assembly 20 is used to convey the fruit box 201, and the fruit box fixing assembly 30 is used to fix the fruit box 201 at the preset station 101 to realize the stacking and unstacking of the fruit box 201. Since the blocking assembly 40 is located downstream of the preset station 101, when the conveying assembly 20 transports the fruit box 201 to the preset station 101, the blocking assembly 40 can block the fruit box 201, so that the fruit box 201 can arrive at the preset station 101 more accurately, thereby improving the fixing effect of the fruit box fixing assembly 30 on the fruit box 201 and ensuring the smooth stacking and unstacking of the fruit box 201. In addition, by setting up the blocking component 40, when the conveying component 20 successively transmits the fruit box 201 to the preset station 101, it can ensure better consistency in the transmission of the fruit box 201 to the preset station 101. That is, the position of the fruit box 201 arriving at the preset station 101 is basically the same each time, which is conducive to improving the accuracy and efficiency of stacking and unloading assembly line operations.

[0041] In this embodiment, the basic principle of destacking is as follows: For example, after the conveying component 20 transports three stacked fruit boxes 201 containing fruits and vegetables to a preset station 101, the fruit box fixing component 30 holds the two upper fruit boxes 201 and moves them upward a certain distance so that the two upper fruit boxes 201 and the bottom fruit box 201 are no longer in contact. At this time, the two upper fruit boxes 201 will not exert pressure on the bottom fruit box 201. The conveying component 20 can continue to transport the bottom fruit box 201 to the downstream station. Then, the fruit box fixing component 30 places the two original upper fruit boxes 201 on the conveying component 20. The above steps are repeated until all fruit boxes 201 are destacking and transported to the downstream station.

[0042] In this embodiment, the basic principle of stacking is as follows: When another conveying component 20 transports a fruit box 201 without fruit or vegetables to another preset workstation 101, the corresponding fruit box fixing component 30 holds the fruit box 201 and moves it upward a certain distance. The conveying component 20 then transports another fruit box 201 without fruit or vegetables to the preset workstation 101, placing it below the previous fruit box 201. Then, the fruit box fixing component 30 places the previous fruit box 201 on top of the current fruit box 201. The above steps are repeated, with the fruit box fixing component 30 lifting the bottommost fruit box 201 and the conveying component 20 transporting the fruit box 201 below these fruit boxes 201, allowing multiple fruit boxes 201 to be stacked sequentially. When a certain number of fruit boxes 201 are stacked, the conveying component 20 transports the stacked fruit boxes 201 to the downstream workstation.

[0043] In some specific embodiments, the conveying component 20 can be a roller conveyor, a belt conveyor, etc.

[0044] Please refer to Figures 4 to 7 In some embodiments, the conveying assembly 20 includes a rotation drive element and at least two rollers 22. The rotation drive element and the rollers 22 are connected in a transmission to drive the rollers 22 to rotate, and a preset gap 102 is formed between any two adjacent rollers 22. The blocking component 40 is located below the roller 22. After the conveying component 20 transports the fruit box 201 to the preset station 101, part of the blocking component 40 can pass through the preset gap 102 to block the fruit box 201.

[0045] In this embodiment, the fruit box 201 is supported and transported by the roller 22. Driven by the rotation drive element, the fruit box 201 can be transported to the preset station 101 through the roller 22. Since a preset gap 102 can be formed between any two adjacent rollers 22, the blocking component 40 can be placed below the roller 22, so as not to affect the transport of the fruit box 201 by the roller 22, making the overall structure of the fruit box conveying device 100 simpler. When the fruit box 201 is transported to the preset station 101, part of the blocking component 40 can pass through the preset gap 102 to block the fruit box 201, thereby achieving precise positioning of the fruit box 201, so that the fruit box 201 can accurately arrive at the preset station 101.

[0046] In some specific embodiments, the rotation drive element can be a motor. This motor can be built into at least one roller 22, each roller 22 having a sprocket at its end, and the sprockets of each roller 22 being connected by a chain drive to enable the rollers 22 to drive together. Alternatively, each roller 22 may have a pulley at its end, and the pulleys of each roller 22 being connected by a belt drive to enable the rollers 22 to drive together.

[0047] In some specific embodiments, the rotation drive element can be a third motor, with each roller 22 having a built-in third motor that drives the corresponding roller 22 to rotate.

[0048] In some specific embodiments, it is understood that the rotation drive element may also be other drive elements capable of driving the roller 22 to rotate, for example, the rotation drive element may be an engine.

[0049] In some embodiments, the blocking assembly 40 includes a first telescopic drive element 42 and a blocking plate 44. The first telescopic drive element 42 is mounted on the mounting base 10 and located below the roller 22, and the blocking plate 44 is mounted on the telescopic end of the first telescopic drive element 42. The first telescopic drive element 42 can drive the barrier plate 44 through the preset gap 102 to block the fruit box 201.

[0050] In this embodiment, when the first telescopic drive element 42 is located below the roller 22, it will not affect the roller 22's transmission of the fruit box 201. The first telescopic drive element 42 can drive the barrier plate 44 through the preset gap 102 to block the fruit box 201. Since the barrier plate 44 has a plate-like structure, it can smoothly pass through the preset gap 102 under the action of the first telescopic drive element 42. Furthermore, the width of the preset gap 102 can be set relatively small to ensure that the roller 22 can effectively support the fruit box 201.

[0051] In some specific embodiments, the first telescopic drive element 42 can be one of a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. The first telescopic drive element 42 is mounted on the mounting base 10 by bolts or the like. The first telescopic drive element 42 drives the barrier plate 44 vertically through or out of the preset gap 102.

[0052] In some embodiments, the number of first telescopic drive elements 42 is at least two, and a barrier plate 44 is installed on the telescopic end of each first telescopic drive element 42.

[0053] In this embodiment, by providing at least two first telescopic drive elements 42, a relatively stable and balanced supporting force can be generated at both ends of the barrier plate 44. This ensures that the barrier plate 44 passes through or exits the preset gap 102 in a relatively balanced and stable manner.

[0054] In some specific embodiments, there are two first telescopic drive elements 42. The telescopic ends of the two first telescopic drive elements 42 are connected to the opposite ends of the barrier plate 44. The two first telescopic drive elements 42 can provide stable support and drive for the barrier plate 44. The barrier plate 44 has a rectangular plate structure. The length direction of the barrier plate 44 is the same as the length direction of the roller 22. The length of the barrier plate 44 is slightly less than the length of the roller 22. The width of the barrier plate 44 is set in the vertical direction.

[0055] In some embodiments, the blocking assembly 40 further includes an adapter 46, the number of which is equal to and corresponds one-to-one with the number of the first telescopic drive element 42; Each adapter 46 includes a base 462 and a mounting shaft 464, the base 462 being mounted on the telescopic end of a corresponding first telescopic drive element 42; The barrier plate 44 has mounting holes 442 that correspond one-to-one with the mounting shaft 464. The barrier plate 44 is mounted on the corresponding mounting shaft 464 through the corresponding mounting holes 442.

[0056] In this embodiment, the base 462 of the adapter 46 is used to be installed on the telescopic end of the corresponding first telescopic drive element 42, and the barrier plate 44 is installed on the corresponding mounting shaft 464 through the mounting hole 442. This arrangement facilitates the installation and replacement of the barrier plate 44 and makes maintenance easier.

[0057] In some specific embodiments, there are two first telescopic drive elements 42 and two adapter seats 46, with one adapter seat 46 provided at the telescopic end of each first telescopic drive element 42. Each end of the barrier plate 44 is provided with a mounting hole 442, and the mounting holes 442 correspond one-to-one with the mounting shafts 464.

[0058] In some embodiments, each seat 462 is provided with a slot 4622, and both ends of each mounting shaft 464 are connected to the opposite side walls of the corresponding slot 4622, and the slots 4622 of all seats 462 are located on the same straight line. The barrier plate 44 is secured in the slot 4622.

[0059] In this embodiment, the slot 4622 is used to accommodate and fix the barrier plate 44. By providing the slot 4622, the connection strength between the barrier plate 44 and the base 462 can be improved. In addition, the slot 4622 also has a positioning function, so that the mounting shaft 464 can be smoothly inserted into the mounting hole 442 of the barrier plate 44.

[0060] In some specific embodiments, through holes are provided on both side walls of the slot 4622, and the mounting shaft 464 is installed on the side walls of the slot 4622 through the through holes, that is, the mounting shaft 464 is located inside the slot 4622. This arrangement facilitates the installation and replacement of the barrier plate 44, and facilitates inspection and maintenance.

[0061] In some embodiments, the conveying assembly 20 is connected to the top of the mounting base 10, the blocking assembly 40 is connected to the bottom of the mounting base 10, the two fruit box fixing assemblies 30 are connected to both ends of the mounting base 10, and the preset station 101 is located between the two fruit box fixing assemblies 30.

[0062] In this embodiment, the blocking component 40 and the conveying component 20 are configured in such a way that they can effectively avoid each other and prevent mutual interference.

[0063] In some specific embodiments, the fruit box fixing assembly 30 is mounted to opposite ends of the mounting base 10 by bolts or the like. The first telescopic drive element 42 of the blocking assembly 40 is mounted to the bottom end of the mounting base 10 by bolts.

[0064] In some embodiments, the fruit box conveying device 100 further includes an adapter plate 50, one end of which is connected to the bottom end of the mounting base 10, and the blocking assembly 40 is connected to the other end of the adapter plate 50.

[0065] In this embodiment, by setting the adapter plate 50, the blocking component 40 can be positioned directly below the preset gap 102, allowing the blocking component 40 and the conveying component 20 to further avoid each other and prevent mutual interference. This also ensures that the blocking component 40 can smoothly pass through the preset gap 102.

[0066] In some specific embodiments, the adapter plate 50 is a rectangular plate structure, and the adapter base 46 is a square tube structure. One end of the adapter plate 50 is bolted to the bottom end of the mounting base 10, and the first telescopic drive element 42 of the blocking assembly 40 is bolted to the other end of the adapter plate 50.

[0067] In some embodiments, the fruit box conveying device 100 further includes a sensing component 60 and a controller; The sensing component 60 is mounted on the mounting base 10 and is located to the side of the preset work station 101; The controller is connected to the sensing component 60, the fruit box fixing component 30, and the barrier component 40 for communication purposes.

[0068] In this embodiment, after the conveying component 20 transports the fruit box 201 to the preset workstation 101, the sensing component 60 can promptly sense the fruit box 201. Under the unified control of the controller, the blocking component 40 can promptly block the fruit box 201, and the fruit box fixing component 30 can fix the fruit box 201.

[0069] In some specific embodiments, the sensing component 60 includes a photoelectric switch, which is mounted on the mounting base 10 and located to the side of the preset workstation 101. The controller is a PLC controller.

[0070] In some embodiments, the fruit box fixing assembly 30 includes a lifting mechanism 32 and a gripping mechanism 34; The lifting mechanism 32 is mounted on the mounting base 10; The gripping mechanism 34 includes a mounting frame 342, a drive unit 344, a first gripper 346 and a second gripper 348. The mounting frame 342 is slidably mounted on the mounting base 10 in the vertical direction. The lifting mechanism 32 is connected to the mounting frame 342 in a transmission to drive the mounting frame 342 to rise and fall in the vertical direction. One end of the first gripper 346 and one end of the second gripper 348 are respectively hinged to the mounting bracket 342. The drive unit 344 is connected to the first gripper 346 and the second gripper 348 respectively to drive the other end of the first gripper 346 and the other end of the second gripper 348 to move closer or further away from each other. The other end of the first gripper 346 and the other end of the second gripper 348 face the preset station 101.

[0071] In this embodiment, the mounting base 10 is used to mount the lifting mechanism 32, which drives the mounting frame 342 to move vertically. When the driving unit 344 drives the other end of the first gripper 346 and the other end of the second gripper 348 to move closer together, it can hold the fruit box 201. When the driving unit 344 drives the other end of the first gripper 346 and the other end of the second gripper 348 to move away from each other, it can release the fruit box 201. When the fruit box 201 is located at the preset work station 101, the driving unit 344 drives the first gripper 346 and the second gripper 348 to hold and release the fruit box 201, thereby enabling the stacking or unstacking of the fruit box 201. Since the first gripper 346 and the second gripper 348 can hold the fruit box 201, the force on the fruit box 201 is better. The gripping force of the first gripper 346 and the second gripper 348 on the fruit box 201 is relatively small. Therefore, the damage to the fruit box 201 can be reduced, and the working power of the drive unit 344 can also be reduced.

[0072] In some specific embodiments, the drive unit 344 includes two second telescopic drive elements 3442, one end of which is hinged to the mounting bracket 342. The other end of one second telescopic drive element 3442 is hinged to the first gripper 346, and the other end of the other second telescopic drive element 3442 is hinged to the first gripper 346, so as to drive the other end of the first gripper 346 and the other end of the second gripper 348 to move closer or further away from each other.
