Description

Technical Field

[0001] This application relates to the field of fruit and vegetable sorting technology, and in particular to a fruit and vegetable container lifting device and a fruit and vegetable sorting equipment. Background Technology

[0002] In some fruit and vegetable sorting operations, workers often need to pick fruits and vegetables from a higher conveyor belt and place them into packing boxes or baskets, which are then transported by a lower conveyor belt. Due to the significant height difference between the two conveyor belts, workers need to frequently bend over to place the fruits and vegetables into the lower containers, or first fill the baskets at the higher level and then move the full containers to the lower conveyor belt. The entire manual picking process is labor-intensive and inefficient in handling the containers. Utility Model Content

[0003] One objective of this application is to provide a fruit and vegetable container lifting device and a fruit and vegetable sorting equipment to solve the technical problems in the related art where manual picking requires a lot of labor and the handling efficiency of fruit and vegetable containers is low.

[0004] This application provides a fruit and vegetable container lifting device, including:

[0005] main body;

[0006] A support platform, used to support part of the bottom of fruit and vegetable containers;

[0007] A lifting mechanism is installed on the main body and connected to the platform, used to drive the platform to rise or fall;

[0008] A rolling assembly, mounted on the main body, is used to support another part of the bottom of the fruit and vegetable container when the platform is lowered to its lowest height, and to allow the fruit and vegetable container to slide.

[0009] With the above structure, when the platform is lowered to its lowest position, the fruit and vegetable containers can be easily transferred by pushing, thereby reducing the intensity of manual handling and improving the transfer efficiency.

[0010] Optionally, the main body includes:

[0011] The base is provided with a receiving groove for partially or completely receiving the platform when it descends, and the rolling assembly is mounted on the base and disposed adjacent to the edge of the receiving groove;

[0012] The column is fixedly connected to the base, and the lifting mechanism is installed on the column.

[0013] The aforementioned structure allows the base to support the rolling assembly and the lowered fruit and vegetable containers, while the column supports the lifting mechanism and the containers during the lifting process, ensuring the overall structural stability. The receiving slot allows the platform to descend to a lower position, ensuring that the containers are stably supported by the rolling assembly and easily slidable for transfer when at their lowest position.

[0014] Optionally, the lifting mechanism includes:

[0015] A linear pneumatic track is installed on the column and extends in the height direction;

[0016] A pneumatic slider slides in conjunction with the linear pneumatic track, and the pneumatic slider can be raised or lowered relative to the linear pneumatic track;

[0017] A control valve, connected to the air passage of the linear pneumatic track, is used to drive the pneumatic slider to rise or fall by controlling the air supply;

[0018] The support is connected to the pneumatic slider and the platform respectively, and is used to follow the movement of the pneumatic slider and drive the platform to rise or fall relative to the linear pneumatic track.

[0019] Through the above structure, the control valve controls the on / off state or direction of the air supply, driving the pneumatic slider to rise or fall along a linear pneumatic track. The bracket moves synchronously with the pneumatic slider, thereby driving the platform to rise and fall. The embodiment of this application uses a pneumatically driven lifting mechanism, which has the advantages of fast response speed and easy control, and uses a bracket as a connecting part to effectively transmit the movement of the pneumatic slider to the platform.

[0020] Optionally, the fruit and vegetable container lifting device further includes a guiding mechanism, the guiding mechanism comprising:

[0021] A guide shaft is mounted on the column and is arranged parallel to the linear pneumatic track.

[0022] The guide slider, which slides in conjunction with the guide shaft and is connected to the bracket, is used to provide guidance during the lifting and lowering of the bracket.

[0023] Through the above structure, the guide mechanism provides additional support and guidance for the lifting and lowering of the support and platform. Working together with the linear pneumatic rail, it can effectively prevent the support and platform from shaking, tilting or rotating during the lifting and lowering process, thus improving the smoothness of operation and positioning accuracy.

[0024] Optionally, the platform includes a first support portion and a second support portion connected to each other in its own length direction. The second support portion is connected to the bracket. When the platform is lowered to its lowest height, the first support portion is received in the receiving groove, while the second support portion and the bracket are located outside the receiving groove.

[0025] With the above structure, the embodiment of this application divides the platform into two parts. Only the first support part of the rolling component supporting the container needs to be lowered to the lowest position to enter the receiving groove, while the second support part of the connecting bracket and the bracket do not need to enter the receiving groove. This avoids interference between the bracket and the base or receiving groove when the bracket is at the lowest position, making the overall structure more compact and reasonable.

[0026] Optionally, the rolling assembly includes a first roller, which is rotatably mounted on the base and disposed adjacent to the edge of the receiving groove, wherein the axial direction of the first roller is perpendicular to the length direction of the receiving groove.

[0027] With the above structure, the axis of the first roller is set perpendicular to the length direction of the receiving groove, so as to allow the container to slide easily along the length direction of the receiving groove.

[0028] Optionally, the fruit and vegetable container lifting device further includes a second roller, which is rotatably mounted on the bracket and disposed adjacent to the connecting portion of the platform, and the axis of the second roller is perpendicular to the length direction of the platform.

[0029] With the above structure, the second roller installed on the bracket and raised and lowered accordingly can provide rolling support when fruit and vegetable containers are placed on the platform or during the lifting process, reducing the friction between the bottom of the fruit and vegetable containers and the connection area of ​​the bracket, so that when the platform descends, it can assist the rolling component in making the fruit and vegetable containers slide.

[0030] Optionally, the fruit and vegetable container lifting device further includes a limiting member, which is connected to the bracket and located on the side of the bracket facing the column. The limiting member is used to restrict the fruit and vegetable container from contacting the column.

[0031] Through the above structure, the limiting component prevents the fruit and vegetable containers from hitting the column and the lifting or guiding mechanism installed on it due to improper placement or accidental movement during the placement or lifting process. It plays a role in physical protection and positioning, ensuring the safety of the equipment and the integrity of the containers.

[0032] Optionally, the fruit and vegetable container lifting device further includes a support column and an auxiliary material platform. One end of the support column is connected to the platform, and the other end of the support column is connected to and supports the auxiliary material platform, which is located above one side edge of the platform.

[0033] With the above structure, operators can place auxiliary materials related to fruit and vegetable processing, such as packaging bags, labels, tools, and small portions of ingredients, on the auxiliary material platform. The auxiliary material platform always maintains a relatively fixed height difference from the platform and is located at the edge of the platform, making it convenient for operators to access the auxiliary materials for their work.

[0034] In another aspect, embodiments of this application provide a fruit and vegetable sorting device, comprising:

[0035] The first conveyor belt is used for transporting fruits and vegetables;

[0036] The second conveyor belt, located below the first conveyor belt, is used to transport fruit and vegetable containers;

[0037] The fruit and vegetable container lifting device as described in any of the above claims is simultaneously located on one side of the first conveyor belt and one side of the second conveyor belt. When the platform of the fruit and vegetable container lifting device is raised to the highest position, it is closer to the first conveyor belt than the second conveyor belt, and when it is lowered to the lowest position, it is closer to the second conveyor belt than the first conveyor belt. The rolling component of the fruit and vegetable container lifting device is located adjacent to the second conveyor belt.

[0038] The embodiments of this application achieve the following technical effects: the lifting mechanism drives the platform to move up and down. When the platform is raised, the fruit and vegetable containers can be lifted to the required height for convenient operation or docking with other devices or equipment. When the platform is lowered to its lowest height, it only supports a portion of the bottom of the container. At this time, the rolling component located on the main body contacts and supports the other part of the bottom of the container, allowing the container to slide on the rolling component for easy insertion or removal. Through the cooperation of the platform and the rolling component, the embodiments of this application enable the convenient transfer of fruit and vegetable containers filled with fruits and vegetables by pushing when the platform is lowered to its lowest position, thereby reducing the intensity of manual handling and improving transfer efficiency.

Detailed Implementation

[0048] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them. The terms "upper," "lower," "left," "right," "upper end," "lower end," "top," and "bottom," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] 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.

[0050] In related technologies, some fruit and vegetable sorting operations require picking fruits and vegetables from higher conveyor belts and placing them into packing boxes or baskets, such as the boxing operation at the end of the sorting process for apples and pears. These fruit and vegetable containers are then transported by a lower conveyor belt. Due to the significant height difference between the two conveyor belts, workers need to frequently bend over to place fruits and vegetables into the lower containers, or first complete the packing at the higher level and then move the full containers to the lower conveyor belt. Therefore, the entire manual picking process requires a lot of labor, and the efficiency of transporting fruit and vegetable containers is low.

[0051] To address the aforementioned technical problems, this application provides a fruit and vegetable container lifting device, applied to fruit and vegetable sorting equipment. Exemplarily, it can be specifically applied to the final packaging process of the fruit and vegetable sorting equipment. The fruit and vegetable container can be a packaging box, fruit basket, or tray, etc.

[0052] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the fruit and vegetable container lifting device 300 includes a main body 10, a platform 20, a lifting mechanism 30, and a rolling assembly 40. The platform 20 supports a portion of the bottom of the fruit and vegetable container. The lifting mechanism 30 is mounted on the main body 10 and connected to the platform 20, and is used to drive the platform 20 to rise or fall. The rolling assembly 40 is mounted on the main body 10 and is used to support another portion of the bottom of the fruit and vegetable container when the platform 20 is lowered to its lowest height, and to allow the fruit and vegetable container to slide.

[0053] The working principle of the fruit and vegetable container transport device in this embodiment is as follows: the lifting mechanism 30 drives the platform 20 to move up and down. When the platform 20 is raised, the fruit and vegetable container can be raised to the required height for convenient operation or docking with other devices or equipment. When the platform 20 is lowered to its lowest height, the platform 20 only supports a part of the bottom of the container. At this time, the rolling component 40 located on the main body 10 will contact and support the other part of the bottom of the container, so that the container can slide on the rolling component 40, which is convenient for moving in or out.

[0054] Understandably, in this embodiment of the application, through the cooperation of the platform 20 and the rolling component 40, when the platform 20 is lowered to its lowest position, the fruit and vegetable container filled with fruits and vegetables can be conveniently transferred by pushing, thereby reducing the intensity of manual handling and improving the transfer efficiency.

[0055] In some embodiments, the rolling assembly 40 may dock with other transport devices or equipment, such as a conveyor belt for transporting fruit and vegetable containers, and the rolling assembly 40 may allow the fruit and vegetable containers to slide in at least one direction by rolling itself. Exemplarily, when the fruit and vegetable containers descend and contact the rolling assembly 40, they can be pushed onto the conveyor belt for transporting fruit and vegetable containers and transported to the next process.

[0056] In some embodiments, the main body 10 includes a base 11 and a column 12. The base 11 is provided with a receiving groove 111 for partially or fully receiving the platform 20 when it descends. A rolling assembly 40 is mounted on the base 11 and disposed adjacent to the edge of the receiving groove 111. The column 12 is fixedly connected to the base 11, and a lifting mechanism 30 is mounted on the column 12.

[0057] Understandably, the base 11 supports the rolling assembly 40 and the lowered fruit and vegetable container, while the column 12 supports the lifting mechanism 30 and the fruit and vegetable container during the lifting process, ensuring the stability of the overall structure. This embodiment of the application provides a receiving groove 111, allowing the platform 20 to descend to a lower position, such as flush with or below the surface of the base 11. This allows the rolling assembly 40 to more effectively support the bottom of the container, ensuring that the container is stably supported by the rolling assembly 40 at its lowest position and is easily slidable and transferred.

[0058] Please see Figure 3 In some embodiments, the lifting mechanism 30 employs a rodless cylinder and includes a linear pneumatic track 31, a pneumatic slider 32, a control valve 33, and a bracket 34. The linear pneumatic track 31 is mounted on the column 12 and extends in the height direction. The pneumatic slider 32 slides with the linear pneumatic track 31, allowing it to rise or fall relative to the track. The control valve 33 is connected to the air passage of the linear pneumatic track 31 and controls the air supply to drive the pneumatic slider 32 to rise or fall. The bracket 34 is connected to both the pneumatic slider 32 and the platform 20, and moves with the pneumatic slider 32, causing the platform 20 to rise or fall relative to the linear pneumatic track 31.

[0059] Understandably, the control valve 33 controls the on / off state or direction of the air supply, driving the pneumatic slider 32 to rise or fall along the linear pneumatic track 31. The bracket 34 moves synchronously with the pneumatic slider 32, thereby driving the platform 20 to rise and fall. The embodiment of this application uses a pneumatically driven lifting mechanism 30, which has the advantages of fast response speed and easy control, and uses the bracket 34 as a connecting member to effectively transmit the movement of the pneumatic slider 32 to the platform 20.

[0060] For example, the control valve 33 is mounted on the column 12. The control valve 33 includes a control switch 331 with three control positions. One control position is used to cause the control valve 33 to control the pneumatic slider 32 to descend, another control position is used to cause the control valve 33 to control the pneumatic slider 32 to stop, and the remaining control position is used to cause the control valve 33 to control the pneumatic slider 32 to ascend. Alternatively, the control switch 331 can be a knob, button, or rocker arm, etc. The drive configuration of the rodless cylinder can refer to the prior art, and will not be described further here.

[0061] In some embodiments, the lifting mechanism 30 may also employ other cylinder types; in other embodiments, the lifting mechanism 30 may also employ other driving methods, such as electric screw lifting mechanism, electric rack and pinion lifting mechanism, chain lifting mechanism, etc., without limitation.

[0062] In some embodiments, the fruit and vegetable container lifting device 300 further includes a guide mechanism 50, which includes a guide shaft 51 and a guide slider 52. The guide shaft 51 is mounted on the column 12 and arranged parallel to the linear pneumatic track 31. The guide slider 52 is slidably engaged with the guide shaft 51 and connected to the bracket 34 to provide guidance during the lifting and lowering of the bracket 34.

[0063] Understandably, the guide mechanism 50 provides additional support and guidance for the lifting and lowering of the support 34 and the platform 20. Working together with the linear pneumatic rail 31, it effectively prevents the support 34 and the platform 20 from swaying, tilting, or rotating during lifting and lowering, thus improving operational stability and positioning accuracy. Furthermore, the guide mechanism 50 shares some of the lateral force or torsional load, helping to protect the linear pneumatic rail 31 and the pneumatic slider 32 and extending their service life.

[0064] In some embodiments, the columns 12 are arranged in pairs and located on opposite sides of the base 11. Each column 12 is equipped with a corresponding linear pneumatic track 31, a pneumatic slider 32, and a guide mechanism 50. The bracket 34 connects the pneumatic slider 32 and guide slider 52 on the two columns 12 respectively. One column 12 is equipped with a single control valve 33, which is connected to the air passage of the linear pneumatic track 31 on each column 12 to achieve simultaneous control of the two pneumatic sliders 32, thereby ensuring that the bracket 34 and the platform 20 can be raised and lowered more smoothly.

[0065] In some embodiments, the platform 20 includes a first support portion 21 and a second support portion 22 connected to each other in its own length direction. The second support portion 22 is connected to the bracket 34. The first support portion 21 is received in the receiving groove 111 when the platform 20 is lowered to its lowest height. At the same time, the second support portion 22 and the bracket 34 are located outside the receiving groove 111 when the platform 20 is lowered to its lowest height.

[0066] Understandably, in this embodiment of the application, the platform 20 is divided into two parts. Only when it needs to be lowered to the lowest position so that the first support part 21 of the rolling assembly 40 supporting the container enters the receiving groove 111, the second support part 22 of the connecting bracket 34 and the bracket 34 do not need to enter the receiving groove 111. This avoids interference between the bracket 34 and the base 11 or the receiving groove 111 when the bracket 34 is in the lowest position, making the overall structure more compact and reasonable.

[0067] In some embodiments, the rolling assembly 40 includes a first roller 41, which is rotatably mounted on the base 11 and disposed adjacent to the edge of the receiving groove 111. The axial direction of the first roller 41 is perpendicular to the length direction of the receiving groove 111.

[0068] Understandably, the axis of the first roller 41 is positioned perpendicular to the length direction of the receiving groove 111 to allow the container to slide easily along the length direction of the receiving groove 111. For example, the receiving groove 111 has first rollers 41 on opposite sides along its length. The number and length of the rollers can be determined based on the bottom area of ​​the fruit and vegetable container and are not limited here. Also for example, the height of the first roller 41 gradually decreases along the direction from the first support 21 to the second support 22, meaning the fruit and vegetable container tends to slide on the rolling assembly 40 in the direction from the first support 21 to the second support 22. This is well-suited for devices or equipment that are docked outside the second support 22, facilitating the sliding of the fruit and vegetable container towards the docking device or equipment.

[0069] In other embodiments, the rolling assembly 40 includes a ball rotatably mounted on the base 11 and disposed adjacent to the edge of the receiving groove 111, allowing the fruit and vegetable container to slide well in multiple directions on the ball.

[0070] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In some embodiments, the fruit and vegetable container lifting mechanism 30 further includes a second roller 60, which is rotatably mounted on the bracket 34 and disposed adjacent to the connection portion of the platform 20. The axis of the second roller 60 is perpendicular to the length direction of the platform 20.

[0071] Understandably, in this embodiment of the application, the second roller 60, which is installed on the bracket 34 and moves up and down with it, can provide rolling support when the fruit and vegetable container is placed on the platform 20 or during the lifting process, reducing the friction between the bottom of the fruit and vegetable container and the connection area of ​​the bracket 34, so that when the platform 20 descends, it can assist the rolling component 40 to slide the fruit and vegetable container.

[0072] Please see Figure 4 In some embodiments, the axis of the second roller 60 is parallel to the axis of the first roller 41, and the second roller 60 is aligned with the first roller 41 when the platform 20 is lowered to the lowest position, and together with the first roller 41, provides sliding support for the fruit and vegetable container.

[0073] In some embodiments, the fruit and vegetable container lifting mechanism 30 further includes a limiting member 70, which is connected to the bracket 34 and is located on the side of the bracket 34 facing the column 12. The limiting member 70 is used to restrict the fruit and vegetable container from contacting the column 12.

[0074] Understandably, the embodiments of this application, by setting the limiting component 70, prevent the fruit and vegetable containers from hitting the column 12 and the lifting mechanism 30 or guide mechanism 50 installed thereon due to improper placement or accidental movement during the placement or lifting process. This plays a role in physical protection and positioning, ensuring the safety of the equipment and the integrity of the containers.

[0075] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the fruit and vegetable container lifting mechanism 30 also includes a support column 80 and an auxiliary material platform 90. One end of the support column 80 is connected to the platform 20, and the other end of the support column 80 is connected to and supports the auxiliary material platform 90. The auxiliary material platform 90 is located above one side edge of the platform 20.

[0076] Understandably, this application embodiment includes a material platform 90 that rises and falls synchronously with the platform 20. Operators can place materials related to fruit and vegetable processing, such as packaging bags, labels, tools, and small portions, on the material platform 90. The material platform 90 always maintains a relatively fixed height difference with the platform 20 and is located at the edge of the platform 20, making it convenient for operators to access the materials for their work.

[0077] In some embodiments, the auxiliary material platform 90 is disposed above the side edge of the first support portion 21 away from the second support portion 22, and correspondingly, the support column 80 is disposed on the side edge of the first support portion 21 away from the second support portion 22. When the fruit and vegetable container is large, this will restrict the fruit and vegetable container 400 from sliding out from the second support portion 22 toward the first support portion 21.

[0078] Please refer to the following: Figure 5 and Figure 6 On the other hand, this application also provides a fruit and vegetable sorting device 1000, including a first conveyor belt 100, a second conveyor belt 200, and the fruit and vegetable container lifting device 300 described in the above embodiments. The first conveyor belt 100 is used to transport fruits and vegetables. The second conveyor belt 200 is located below the first conveyor belt 100 and is used to transport fruit and vegetable containers 400. The fruit and vegetable container lifting device 300 is simultaneously located on one side of the first conveyor belt 100 and one side of the second conveyor belt 200. When the platform 20 of the fruit and vegetable container lifting device 300 is raised to its highest position, it is closer to the first conveyor belt 100 than the second conveyor belt 200, and when it is lowered to its lowest position, it is closer to the second conveyor belt 200 than the first conveyor belt 100. The rolling component 40 of the fruit and vegetable container lifting device 300 is disposed adjacent to the second conveyor belt 200.

[0079] Understandably, the fruit and vegetable container lifting device 300 is located on one side of the first conveyor belt 100 and the other side of the second conveyor belt 200. When it rises to the highest position, the platform 20 is closer to the upper first conveyor belt 100, which facilitates receiving fruits and vegetables from the first conveyor belt 100 and loading them into containers, or sending the fruit and vegetable containers 400 filled with fruits and vegetables to a height close to the first conveyor belt 100. When it descends to the lowest position, the platform 20 is closer to the lower second conveyor belt 200, and the rolling component 40 is close to the second conveyor belt 200, which facilitates receiving empty fruit and vegetable containers 400 from the second conveyor belt 200, or transferring fruit and vegetable containers 400 filled with fruits and vegetables to the second conveyor belt 200 via the rolling component 40, thus realizing the transfer of fruit and vegetable containers 400 between conveyor belts at different heights.
