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 mechanism and a fruit and vegetable sorting device. Background Technology

[0002] Currently, fruits and vegetables are a type of food that people often consume. Fruits and vegetables include citrus fruits, cherries, apples, pears, and tomatoes. After ripening, fruits and vegetables need to be harvested and then transported to factories for sorting and processing to facilitate subsequent packaging and sales.

[0003] In related technologies, after sorting fruits and vegetables, the fruit and vegetable sorting device will transport them to a corresponding output channel. The fruits and vegetables can enter the packing area through the output channel and be packed into fruit boxes in the packing area. In order to pack fruits and vegetables quickly, the fruit and vegetable sorting device can generally include a packing mechanism and a fruit box conveying mechanism. The fruit box conveying mechanism can transport empty fruit boxes to the packing mechanism, and the packing mechanism packs the fruits and vegetables into the fruit boxes.

[0004] However, after the fruits and vegetables are packed, they may be arranged irregularly inside the fruit box, and there may be large gaps at the bottom of the fruit box, which makes it easy for the fruits and vegetables to roll inside the fruit box during transportation, making the fruit box unstable during transportation. Utility Model Content

[0005] The present invention aims to provide a fruit box conveying mechanism and a fruit and vegetable sorting device to solve the technical problems in the prior art where fruits and vegetables easily roll inside the fruit box during the conveying process, and the fruit box is unstable during the conveying process.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution:

[0007] A fruit box conveying mechanism is provided, comprising:

[0008] include:

[0009] frame;

[0010] A conveying assembly, which is mounted on the frame, is used to convey fruit boxes;

[0011] A positioning component is mounted on the frame and is used to position or deposition the fruit box on the conveying component.

[0012] A shaking component is mounted on the frame and is used to drive the fruit box of the positioning component to shake. In the conveying direction of the conveying component, the shaking component is located between the output end of the conveying component and the positioning component.

[0013] With the above structure, when the conveying component transports the fruit box to the positioning component, the positioning component can position the fruit box so that the fruit box can be fixed on the conveying component. Then, the user can use a fruit and vegetable grabbing device to put the fruit and vegetables into the fruit box, such as a robotic arm or suction cup. When the fruit box is full of fruit and vegetables, the positioning component releases the positioning of the fruit box. The conveying component can continue to move the fruit box.

[0014] When the fruit box moves to the positioning component, the shaking component drives the fruit box to shake as it passes the positioning component, causing the fruits and vegetables inside the fruit box to roll. This allows the fruits and vegetables inside the fruit box to fill the gaps, thus arranging them more evenly and flatly, in order to prevent the fruits and vegetables from rolling inside the fruit box during transportation.

[0015] In some embodiments, the fruit box conveying mechanism further includes a clamping and limiting component, which is mounted on the frame and arranged sequentially with the positioning component along the conveying direction of the conveying component; the clamping and limiting component is used to clamp or release the fruit box on the conveying component.

[0016] With the above structure, the clamping and limiting components and the positioning components are arranged sequentially along the conveying direction of the conveying components; the clamping and limiting components are used to clamp or release the fruit boxes on the conveying components; when the positioning component positions a fruit box, and the user puts fruits and vegetables into the fruit box located at the positioning component, the clamping and limiting components can clamp another empty fruit box to prevent the conveying components from moving the empty fruit box and hitting the fruit box located at the positioning component; thus improving the stability of the fruit boxes during the fruit and vegetable packing process.

[0017] In some embodiments, the clamping and limiting component includes:

[0018] A fixing clamp is mounted on the frame and located on one side of the conveying assembly;

[0019] A pushing component, which is mounted on the frame and located on the side of the conveying assembly opposite to the fixed clamping member;

[0020] A movable clamping member is mounted on the pushing member, and the pushing member is used to push the movable clamping member to move toward or away from the fixed clamping member.

[0021] With the above structure, when the conveying component moves the empty fruit box to the movable clamping member, the pushing component can drive the movable clamping member to move toward the fixed clamping member. The movable clamping member contacts and pushes the empty fruit box toward the fixed clamping member so that the fixed clamping member and the movable clamping member can clamp the fruit box.

[0022] Once the fruit box located at the positioning component has finished packing, the positioning component releases the positioning of the fruit box full of fruits and vegetables, and the pushing component drives the moving clamp to move away from the fixed clamp. The clamping and limiting component releases the empty fruit box on the conveying component, so that the conveying component can move the empty fruit box to the positioning component, thereby realizing automated packing and improving packing efficiency.

[0023] In some embodiments, the fixing clamp includes a first limiting wall, which is perpendicular to the horizontal plane and parallel to the conveying direction of the conveying assembly, and the first limiting wall is located on the side of the fixing clamp facing the pushing component;

[0024] The movable clamping member includes a second limiting wall, which is perpendicular to the horizontal plane and parallel to the conveying direction of the conveying assembly. The second limiting wall is located on the side of the movable clamping member facing the fixed clamping member.

[0025] With the above structure, the first limiting wall is perpendicular to the horizontal plane and parallel to the conveying direction of the conveying assembly. The first limiting wall is located on the side of the fixed clamp facing the pushing component. This makes the first limiting wall parallel to one side of the fruit box. The contact area between the first limiting wall and the fruit box is large during the process of pushing the fruit box, so that the first limiting wall can push the fruit box more stably and prevent the fruit box from rotating during the process of being pushed.

[0026] The second limiting wall is perpendicular to the horizontal plane and parallel to the conveying direction of the conveying assembly. The second limiting wall is located on the side of the movable clamping member facing the fixed clamping member. The second limiting wall can be parallel to the first limiting wall so that the first limiting wall and the second limiting wall can clamp the fruit box more stably.

[0027] In some embodiments, the positioning component includes:

[0028] A lifting component, the lifting component being mounted on the frame;

[0029] A positioning component is installed on the lifting component. The lifting component is used to drive the positioning component to protrude out of or retract from the upper surface of the conveying assembly. When the positioning component protrudes from the upper surface of the conveying assembly, the positioning component lifts the fruit box on the conveying assembly and positions the fruit box. When the positioning component retracts from the upper surface of the conveying assembly, the fruit box falls onto the conveying assembly, and the positioning component releases the positioning of the fruit box.

[0030] With the above structure, when the lifting component lifts the positioning component, the lifting component protrudes relative to the upper surface of the conveying assembly. The lifting component can contact the lower surface of the fruit box and lift the fruit box, causing it to detach from the upper surface of the conveying assembly. Consequently, the conveying assembly stops moving the fruit box, thus achieving the positioning function of the positioning component. When the lifting component retracts the positioning component, the lifting component retracts relative to the upper surface of the conveying assembly. The lifting component can then cause the lower surface of the fruit box to fall onto the upper surface of the conveying assembly, allowing the conveying assembly to continue moving the fruit box.

[0031] In some embodiments, the lifting component includes a cylinder, the pushing direction of the cylinder of the lifting component is perpendicular to the horizontal plane; the positioning component includes a first connecting plate and a second connecting plate, the lower surface of the first connecting plate is connected to the lifting component, the first connecting plate is parallel to the horizontal plane, and the second connecting plate is connected to the side of the first connecting plate opposite to the clamping and limiting component, the second connecting plate is perpendicular to the horizontal plane.

[0032] With the above structure, during the process of the lifting component lifting the positioning component, the second connecting plate can first protrude relative to the upper surface of the conveying component, and the fruit box moving on the conveying component can contact the second connecting plate. The second connecting plate plays a limiting role for the fruit box to prevent the fruit box from passing over the lifting component. Subsequently, the first connecting plate protrudes relative to the upper surface of the conveying component, and the first connecting plate can contact the lower surface of the fruit box and lift the fruit box.

[0033] In some embodiments, the end of the lifting member facing away from the positioning member is rotatably connected to the frame. The positioning member includes a support plate and a rotating frame. The lower side of the rotating frame is rotatably connected to the frame, and the upper side of the rotating frame is rotatably connected to the support plate. The support plate is parallel to the horizontal plane. The lifting member is connected to the rotating frame. The lifting member is used to push the rotating frame to rotate relative to the frame, so as to cause the support plate to protrude out or retract from the upper surface of the conveying assembly.

[0034] With the above structure, the lifting component can push the rotating frame to rotate relative to the frame. The lower side of the frame is fixed in height. During the rotation of the rotating frame relative to the frame, it can drive the upper side of the frame to rise or fall, thereby driving the support plate to rise or fall. In turn, the support plate can lift or lower the fruit box on the conveying component.

[0035] In addition, during the rotation of the rotating frame relative to the machine frame, the support plate makes an arc motion so that when the support plate contacts the fruit box, both the support plate and the fruit box have a certain initial velocity in the horizontal direction. As a result, the fruit box is difficult to fall off relative to the support plate during the process of the support plate lifting the fruit box.

[0036] In some embodiments, the conveying assembly includes a drive component, sprockets, a rotating link, and two parallel conveying chains. Each end of the conveying chain is fitted with one of the sprockets. The drive component is located at the input end of the conveying assembly. The two ends of the rotating link are respectively connected to the two sprockets located at the input end of the conveying assembly. The drive component is used to drive the rotating link to rotate, so as to drive the two conveying chains to move synchronously.

[0037] With the above structure, the conveying assembly includes two parallel conveying chains, which can more stably support the fruit box; and the space between the two conveying chains can provide installation space for the positioning component. In addition, the same drive component can drive the two conveying chains to move synchronously at the same time, which simplifies the structure of the conveying assembly and improves the synchronization of the two conveying chains.

[0038] In some embodiments, the shaking assembly includes two shaking components located on both sides of the conveying assembly. Each shaking component includes a vertical drive and an abutment. The vertical drive is mounted on the frame, and the abutment is connected to the vertical drive. The vertical drive is used to drive the abutment to protrude out of or retract into the upper surface of the conveying assembly.

[0039] The positioning component is located between the two conveyor chains, and the positioning component and the shaking component are located at the same point in the conveying direction of the conveyor components.

[0040] With the above structure, the two shaking components are located on both sides of the conveying assembly. The two shaking components can alternately lift the fruit box so that the fruit box shakes back and forth, making it easier to roll the fruits and vegetables inside the fruit box into the gaps inside the fruit box, and making the fruits and vegetables on the surface of the fruit box more even.

[0041] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the fruit box conveying mechanism in any of the above embodiments.

[0042] Compared with existing technologies, when the conveying component transports the fruit box to the positioning component, the positioning component can position the fruit box so that it can be fixed on the conveying component. Then, the user can use a fruit and vegetable grabbing device to load the fruit and vegetables into the fruit box, such as a robotic arm or suction cup. When the fruit box is full of fruit and vegetables, the positioning component releases the positioning of the fruit box, and the conveying component can continue to move the fruit box.

[0043] When the fruit box moves to the positioning component, the shaking component drives the fruit box to shake as it passes the positioning component, causing the fruits and vegetables inside the fruit box to roll. This allows the fruits and vegetables inside the fruit box to fill the gaps, thus arranging them more evenly and flatly, in order to prevent the fruits and vegetables from rolling inside the fruit box during transportation.

[0053] 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.

[0054] The following detailed description, in conjunction with all the accompanying drawings, of a fruit box conveying mechanism 100 and a fruit and vegetable sorting device provided in this application through specific embodiments, will be provided in detail.

[0055] Please refer to Figure 1 and Figure 2 One embodiment of this utility model discloses a fruit box conveying mechanism 100, including a frame 10, a conveying component 20, a positioning component 30, and a shaking component 40; the conveying component 20 is installed on the frame 10 and is used to convey fruit boxes; the positioning component 30 is installed on the frame 10 and is used to position or deposition the fruit boxes on the conveying component 20; the shaking component 40 is installed on the frame 10 and is used to drive the fruit boxes located on the positioning component 30 to shake; in the conveying direction of the conveying component 20, the shaking component 40 is located between the output end of the conveying component 20 and the positioning component 30.

[0056] With the above structure, when the conveying component 20 conveys the fruit box to the positioning component 30, the positioning component 30 can position the fruit box so that the fruit box can be fixed on the conveying component 20. Then, the user can use a fruit and vegetable grabbing device to put the fruit and vegetables into the fruit box, such as a robotic arm or a suction cup. When the fruit box is full of fruit and vegetables, the positioning component 30 releases the positioning of the fruit box. The conveying component 20 can continue to move the fruit box.

[0057] When the fruit box moves to the positioning component 30, the shaking component 40 drives the fruit box that has passed the positioning component 30 to shake, so that the fruits and vegetables in the fruit box roll, so that the fruits and vegetables in the fruit box fill the gaps in the fruit box, and thus the fruits and vegetables in the fruit box can be arranged more evenly and flatly; in order to prevent the fruits and vegetables in the fruit box from rolling inside the fruit box during transportation.

[0058] Specifically, in this embodiment, the frame 10 may include a steel support frame and legs. The support frame may be formed by splicing steel bars and plates. The support frame is used to support the conveying assembly 20 and to house the positioning assembly 30 and the shaking assembly 40. The legs may be installed at the bottom of the support frame and provide support for it. The conveying assembly 20 may include a motor-driven conveyor chain, and the positioning assembly 30 may include a cylinder-driven steel block. The steel block is used to lift the fruit box, causing it to detach from the conveying assembly 20 to position the fruit box.

[0059] The shaking component 40 may include a cylinder-driven steel block. The shaking component 40 may be distributed on both sides of the conveying component 20. Two shaking components 40 may alternately push up the opposite sides of the fruit box to drive the fruit box to shake. In the conveying direction of the conveying component 20, the shaking component 40 may be located at the same position as the positioning component 30 so that the shaking component 40 can drive the fruit box passing through the positioning component 30 to shake.

[0060] In other embodiments, the frame 10 may also include other structures, such as a hollow box structure; the conveying assembly 20 may also include other structures, such as a motor-driven conveyor belt; the positioning assembly 30 may also include other structures, such as a cylinder-driven rotating frame; the shaking structure may also include other structures, such as a mechanism that clamps the fruit box and drives the fruit box to shake horizontally; in the conveying direction of the conveying assembly 20, the positioning assembly 30 and the shaking assembly 40 may also be arranged in sequence. After the fruit box at the positioning assembly 30 is filled with fruits and vegetables, the fruit box moves to the shaking assembly 40, and the shaking assembly 40 can also drive the fruit box of the positioning assembly 30 to shake.

[0061] In some embodiments, the fruit box conveying mechanism 100 further includes a clamping and limiting component 50, which is mounted on the frame 10. The clamping and limiting component 50 and the positioning component 30 are arranged sequentially along the conveying direction of the conveying component 20. The clamping and limiting component 50 is used to clamp or release the fruit box on the conveying component 20.

[0062] With the above structure, the clamping and limiting component 50 and the positioning component 30 are arranged sequentially along the conveying direction of the conveying component 20; the clamping and limiting component 50 is used to clamp or release the fruit box on the conveying component 20; when the positioning component 30 positions a fruit box, and the user puts fruits and vegetables into the fruit box located at the positioning component 30, the clamping and limiting component 50 can clamp another empty fruit box to prevent the conveying component 20 from moving the empty fruit box and hitting the fruit box located at the positioning component 30; thus improving the stability of the fruit box during the fruit and vegetable packing process.

[0063] Specifically, in this embodiment, the clamping and limiting component 50 may include a cylinder-driven clamping block and a fixed clamping member. The clamping block can push one side of the empty fruit box and cause the other opposite side of the empty fruit box to abut against the fixed clamping member, so that the fruit box is fixed on the conveying component 20.

[0064] In other embodiments, the clamping and limiting component 50 may further include two cylinder-driven clamping blocks, which may abut against opposite sides of the empty fruit box to limit the position of the empty fruit box.

[0065] In some embodiments, the clamping and limiting assembly 50 includes a fixed clamping member 52, a pushing member 54, and a movable clamping member 56; the fixed clamping member 52 is mounted on the frame 10 and is located on one side of the conveying assembly 20; the pushing member 54 is mounted on the frame 10 and is located on the side of the conveying assembly 20 opposite to the fixed clamping member 52; the movable clamping member 56 is mounted on the pushing member 54, and the pushing member 54 is used to push the movable clamping member 56 to move toward or away from the fixed clamping member 52.

[0066] With the above structure, when the conveying component 20 moves the empty fruit box to the movable clamping member 56, the pushing component 54 can drive the movable clamping member 56 to move toward the fixed clamping member 52. The movable clamping member 56 contacts and pushes the empty fruit box toward the fixed clamping member 52, so that the fixed clamping member 52 and the movable clamping member 56 can clamp the fruit box.

[0067] After the fruit box located at the positioning component 30 is filled, the positioning component 30 releases the positioning of the fruit box filled with fruits and vegetables, and the pushing component 54 drives the moving clamping component 56 to move away from the fixed clamping component 52. The clamping and limiting component 50 releases the empty fruit box on the conveying component 20, so that the conveying component 20 can drive the empty fruit box to the positioning component 30 to realize automated boxing and improve boxing efficiency.

[0068] Specifically, in this embodiment, the fixed clamping member 52 may include a steel bar, which may be parallel to the conveying direction of the conveying assembly 20; the pushing member 54 may include a cylinder, the pushing direction of the pushing member 54 is perpendicular to the conveying direction of the conveying assembly 20 and parallel to the horizontal plane, the cylinder body of the cylinder of the pushing member 54 may be fixed to the frame 10 by a threaded connection, and the piston rod of the cylinder of the pushing member 54 may be fixed to the movable clamping member 56; the movable clamping member 56 may include a rectangular metal plate.

[0069] In other embodiments, the fixing clamp 52 may also include other structures, such as a cuboid block structure; the pushing component 54 may also include other structures, such as an electric motor fixed to the frame 10.

[0070] In some embodiments, the fixing clamp 52 includes a first limiting wall 522, which is perpendicular to the horizontal plane and parallel to the conveying direction of the conveying assembly 20, and is located on the side of the fixing clamp 52 facing the pushing member 54; the moving clamp 56 includes a second limiting wall 562 (see... Figure 5 The second limiting wall 562 is perpendicular to the horizontal plane and parallel to the conveying direction of the conveying assembly 20. The second limiting wall 562 is located on the side of the movable clamping member 56 facing the fixed clamping member 52.

[0071] With the above structure, the first limiting wall 522 is perpendicular to the horizontal plane and parallel to the conveying direction of the conveying assembly 20. The first limiting wall 522 is located on the side of the fixed clamping member 52 facing the pushing member 54. This makes the first limiting wall 522 parallel to one side of the fruit box. The contact area between the first limiting wall 522 and the fruit box is large during the process of pushing the fruit box, so that the first limiting wall 522 can push the fruit box more stably and prevent the fruit box from rotating during the process of being pushed.

[0072] The second limiting wall 562 is perpendicular to the horizontal plane and parallel to the conveying direction of the conveying assembly 20. The second limiting wall 562 is located on the side of the movable clamping member 56 facing the fixed clamping member 52. The second limiting wall 562 can be parallel to the first limiting wall 522 so that the first limiting wall 522 and the second limiting wall 562 can clamp the fruit box more stably.

[0073] Specifically, in this embodiment, the first limiting wall 522 can be a long rectangular plane, and the length of the first limiting wall 522 is adapted to the length of the conveying component 20; the second limiting wall 562 can be a rectangular plane, the width of the second limiting wall 562 is greater than the width of the first limiting wall 522, and the length of the second limiting wall 562 is less than the length of the second limiting wall 562.

[0074] In other embodiments, the shape of the first limiting wall 522 may be other, such as circular or elliptical; the shape of the second limiting wall 562 may also be the same as that of the first limiting wall 522.

[0075] Please refer to Figure 3 In some embodiments, the positioning component 30 includes a lifting component 32 and a positioning component 34; the lifting component 32 is mounted on the frame 10; the positioning component 34 is mounted on the lifting component 32, and the lifting component 32 is used to drive the positioning component 34 to protrude out of or retract from the upper surface of the conveying component 20; when the positioning component 34 protrudes out of the upper surface of the conveying component 20, the positioning component 34 lifts the fruit box on the conveying component 20 and positions the fruit box; when the positioning component 34 retracts into the upper surface of the conveying component 20, the fruit box falls onto the conveying component 20, and the positioning component 34 releases the positioning of the fruit box.

[0076] With the above structure, when the lifting member 32 lifts the positioning member 34, the lifting member 32 protrudes relative to the upper surface of the conveying assembly 20. The lifting member 32 can contact the lower surface of the fruit box and lift the fruit box, so that the fruit box is separated from the upper surface of the conveying assembly 20. Therefore, the conveying assembly 20 no longer moves the fruit box, thus achieving the positioning function of the positioning member 30. When the lifting member 32 retracts the positioning member 34, the lifting member 32 retracts relative to the upper surface of the conveying assembly 20. The lifting member 32 can cause the lower surface of the fruit box to fall onto the upper surface of the conveying assembly 20, allowing the conveying assembly 20 to continue moving the fruit box.

[0077] Specifically, in this embodiment, the lifting component 32 may include a cylinder. The cylinder body of the lifting component 32 can be fixed to the frame 10 by threaded connection or welding. The piston rod of the lifting component 32 cylinder can be connected to the lower surface of the positioning component 34. The positioning component 34 may include two mutually perpendicular sheet metal structures.

[0078] In other embodiments, the lifting component 32 may also include other parts, such as an electric motor; the positioning component 34 may also include other structures, such as a cuboid block structure.

[0079] In some embodiments, the lifting member 32 includes a cylinder, and the pushing direction of the cylinder of the lifting member 32 is perpendicular to the horizontal plane; the positioning member 34 includes a first connecting plate 342 and a second connecting plate 344, the lower surface of the first connecting plate 342 is connected to the lifting member 32, the first connecting plate 342 is parallel to the horizontal plane, and the second connecting plate 344 is connected to the side of the first connecting plate 342 facing away from the clamping and limiting component 50, and the second connecting plate 344 is perpendicular to the horizontal plane.

[0080] With the above structure, during the process of lifting the positioning component 34 by the lifting component 32, the second connecting plate 344 can first protrude relative to the upper surface of the conveying component 20. The fruit box moving on the conveying component 20 can contact the second connecting plate 344, and the second connecting plate 344 plays a limiting role for the fruit box to prevent the fruit box from passing over the lifting component 32. Subsequently, the first connecting plate 342 protrudes relative to the upper surface of the conveying component 20. The first connecting plate 342 can contact the lower surface of the fruit box and lift the fruit box so that the fruit box is separated from the conveying component 20.

[0081] Specifically, both the first connecting plate 342 and the second connecting plate 344 can be rectangular plate structures, and the first connecting plate 342 and the second connecting plate 344 can be integrally formed.

[0082] Please refer to Figure 4 In some other embodiments, the end of the lifting member 32 facing away from the positioning member 34 is rotatably connected to the frame 10. The positioning member 34 includes a support plate 36 and a rotating frame 38. The lower side of the rotating frame 38 is rotatably connected to the frame 10, and the upper side of the rotating frame 38 is rotatably connected to the support plate 36. The support plate 36 is parallel to the horizontal plane. The lifting member 32 is connected to the rotating frame 38. The lifting member 32 is used to push the rotating frame 38 to rotate relative to the frame 10, so as to drive the support plate 36 to protrude or retract from the upper surface of the conveying assembly 20.

[0083] With the above structure, the lifting component 32 can push the rotating frame 38 to rotate relative to the frame 10. The lower side of the frame 10 is fixed in height. During the rotation of the rotating frame 38 relative to the frame 10, it can drive the upper side of the frame 10 to rise or fall, thereby driving the support plate 36 to rise or fall. In turn, the support plate 36 can lift or lower the fruit box on the conveying assembly 20.

[0084] In addition, during the rotation of the rotating frame 38 relative to the frame 10, the support plate 36 makes an arc motion so that when the support plate 36 contacts the fruit box, both the support plate 36 and the fruit box have a certain initial velocity in the horizontal direction. As a result, during the process of the support plate 36 lifting the fruit box, the fruit box is difficult to fall off relative to the support plate 36.

[0085] Specifically, the support plate 36 can be made of rectangular sheet metal. The lower surface of the support plate 36 can be connected to the fixing block by welding or threading. The fixing block can be rotatably connected to the rotating frame 38 by a rotating shaft. The rotating frame 38 can include four parallel rotating rods 382. The four rotating rods 382 are located at the four corners of the support plate 36.
