Description
Technical Field
[0001] This application relates to the field of fruit packaging technology, and in particular to a flipping device for storing fruit frames. Background Technology
[0002] Fruit storage involves various factors, including the type of fruit, shelf life, storage conditions, and storage methods. Different types of fruit have different shelf lives and storage requirements. Generally, berries have a shorter shelf life, typically only 37 days; citrus fruits are more resistant to storage and can be kept for 23 weeks; apples and pears, among others, can be kept for weeks or even months under suitable conditions; tropical fruits have a shorter shelf life at room temperature, but refrigeration can extend their shelf life. Currently, in fruit-growing areas, after harvest, fruits cannot be packaged and sold immediately. To prevent spoilage, they are usually loaded into crates and transferred to cold storage. Packaging, transportation, and sales are then carried out as needed based on market demand.
[0003] Currently, fruits (such as kiwifruit) stored in cold storage are typically transferred from the cold storage to the packing line's conveyor belt using forklifts before packaging. The fruit inside the crates is then unloaded onto the conveyor belt for transport. After transport, the fruit undergoes sorting, visual inspection, boxing (or cartoning), and is loaded onto trucks for transport. However, currently, when unloading the fruit from the crates onto the conveyor belt, if... Figure 1 As shown, the process typically involves using a forklift to lift the crates and place them on a support frame on one side of the conveyor belt. The fruit inside is then manually turned over, causing it to spill onto the conveyor belt for transport. Due to the large size of the crates and the large amount of fruit stored within, manual turning is physically demanding. Furthermore, the rapid spillage after turning not only causes crushing damage among the fruit but also results in fruit falling from the conveyor belt to the ground, further damaging the fruit and increasing costs while reducing profits. Utility Model Content
[0004] To address the aforementioned problems, this application aims to provide a turning device for fruit storage frames, which can realize the mechanized dumping of fruit inside the frames, solving the problem of the heavy physical burden of manual turning and the loss of fruit due to crushing caused by excessively fast manual dumping.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a flipping device for storing fruit frames, the flipping device including an L-shaped support frame connected to one side of the conveyor belt, a flipping frame hinged on the L-shaped support frame to support the frame and drive the frame to flip so that it contacts the surface of the conveyor belt, and a driving component on the L-shaped support frame to drive the flipping frame to flip gradually.
[0006] Preferably, the overturning frame body is L-shaped structure, including a vertical rod hinged with the L-shaped support frame at the end, and a horizontal rod horizontally connected at the bottom of the vertical rod, and a supporting rod is symmetrically arranged at the middle position of the horizontal rod on one side, and a limiting rod is horizontally arranged at the top end of each supporting rod and can contact the top of the frame body.
[0007] Preferably, a roller is symmetrically arranged between the opposite horizontal rods, and an insertion slot is formed in each roller for inserting the insertion plate.
[0008] Preferably, a baffle is symmetrically arranged at the two ends of the limiting rod close to the conveying belt and located on the two sides of the conveying belt, and a retractable corrugated plate is arranged on the side edge close to the conveying belt.
[0009] The beneficial effects of the present application are: the overturning device can realize the mechanical dumping of the fruits in the frame body through the overturning frame body, which can avoid the problem of crushing and falling to the ground of the fruits caused by the too fast manual overturning of the frame body, and solve the problem of heavy physical burden in the current manual overturning.

[0026] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.
[0027] See attached document Figures 1-15 The diagram shows a flipping device for storing fruit frames, such as... Figure 8 As shown, the flipping device includes an L-shaped support frame 1 connected to one side of the conveyor belt, which is preferably fixed to the ground (using expansion bolts). A flipping frame 2 is hinged to the L-shaped support frame 1 to support the frame and, after the frame is flipped, to contact the surface of the conveyor belt. A driving component (preferably a drive cylinder) is provided on the L-shaped support frame 1 to drive the flipping frame 2 to flip gradually. During operation, the frame is transferred to the flipping frame 2 using a forklift's insert plate, and the insert plate is then removed. The drive cylinder then drives the flipping frame 2 and the entire frame to flip. During the flipping process, the fruit inside the frame gradually pours onto the conveyor belt. The drive cylinder drives the frame to flip at a uniform speed, avoiding the problem of fruit being completely poured out in a short time due to the current manual flipping method, which causes crushing and damage to the fruit upon falling to the ground. Simultaneously, this flipping device achieves mechanical frame flipping, solving the problem of the heavy physical burden of manual flipping.
[0028] Specifically, such as Figures 2-3As shown, the tilting frame 2 has an L-shaped structure, including a vertical rod 21 hinged at one end to an L-shaped support frame 1, and a horizontal rod 22 connected horizontally to the bottom of the vertical rod 21. The horizontal rod 22 is detached from the ground and is used to support the frame being transferred by the forklift. During the process of tilting the frame and dumping the fruit using the drive cylinder, to prevent the frame from detaching from the tilting frame 2, as follows... Figures 2-3 As shown, support rods 23 are spaced apart at the middle of the horizontal bar 22 on one side. At the top of each support rod 23, a limiting rod 24 is horizontally positioned towards the other horizontal bar 22 and can contact the top of the frame. After the frame is transferred by forklift and placed on the horizontal bar 22, the limiting rods 24 at the top of the support rods 23 provide a similar limiting effect on the top of the frame during the flipping process. Figure 7 As shown, this configuration effectively prevents the frame from detaching from the flipping frame 2 and falling off after flipping.
[0029] like Figures 5-6 As shown, after the frame is transferred between the horizontal bar 22 and the limiting bar 24 using the forklift's insert plate, the forklift needs to move backward to disengage the insert plate from the bottom of the frame. Therefore, the frame needs to be limited to disengage the insert plate. Figure 2 , 5 As shown in Figure -6, rollers 3 are connected at intervals between the opposing horizontal bars 22, and as shown in Figure -6. Figure 10 As shown, since the length of the vertical support legs of the frame is usually greater than its internal height, after the frame is transferred to the horizontal bar 22 via the insert plate, the frame is lowered so that its support legs are limited in the horizontal direction by the rollers 3, as shown. Figure 6 As shown in the diagram, during the forklift's backward movement of the insert plate, the roller 3 blocks the plate, allowing it to smoothly detach from the frame. Simultaneously, during the plate's detachment, the rolling contact with the roller 3 reduces the resistance during ejection.
[0030] During the process of detaching the insert from the frame, the insert moves and slides, causing wear and tear on the bottom of the frame. Additionally, the frame contains a significant amount of fruit, making it quite heavy. This results in considerable wear and noise during the insert's removal. Furthermore, the frame will sag after the insert is completely removed (e.g., ...). Figure 10 As shown by the middle arrow, this causes gravitational compression of the fruit at the bottom of the frame, and after the fruit has been unloaded, it is difficult for the insert plate to be reinserted between the adjacent frame and the roller to remove the empty frame. Therefore, to solve this problem, as... Figures 11-13As shown, the insertion slot 3a is opened on each roller 3 to insert the insertion plate to lift the frame. The depth of the insertion slot 3a is slightly larger than the thickness of the insertion plate. When the insertion plate transfers the frame to the roller, the insertion plate is inserted into the insertion slot 3a, so that the frame is directly contacted and received by the roller. Then the insertion plate can be removed without contacting the frame, thereby effectively solving the problem of large sliding wear between the insertion plate and the frame when the insertion plate is removed, and the problem of gravity extrusion of the fruit in the frame when the frame falls after the insertion plate is removed. After the fruit is poured, the insertion plate can be inserted into the insertion slot 3a to smoothly unload the frame from the roller 3.
[0031] When the above fruit pouring is performed, after the frame is turned to a certain angle, the fruit in the frame inevitably speeds up the pouring under the action of gravity, thereby the problem of the fruit falling to the ground and being damaged still exists. Therefore, in order to solve this problem, as shown, Figures 14-15 As shown, the insertion slot 3a is opened on each roller 3 to insert the insertion plate to lift the frame. The depth of the insertion slot 3a is slightly larger than the thickness of the insertion plate. When the insertion plate transfers the frame to the roller, the insertion plate is inserted into the insertion slot 3a, so that the frame is directly contacted and received by the roller. Then the insertion plate can be removed without contacting the frame, thereby effectively solving the problem of large sliding wear between the insertion plate and the frame when the insertion plate is removed, and the problem of gravity extrusion of the fruit in the frame when the frame falls after the insertion plate is removed. After the fruit is poured, the insertion plate can be inserted into the insertion slot 3a to smoothly unload the frame from the roller 3.
[0032] However, when the frame starts to turn, the baffle 4 cannot be close to the surface of the conveying belt, so the blocking effect on the fruit is limited. If the width of the baffle 4 is increased, the turning angle of the frame 4 will be limited, and the fruit in the frame cannot be completely poured out. Therefore, in order to solve this problem, as shown, Figure 15 As shown, the insertion slot 3a is opened on each roller 3 to insert the insertion plate to lift the frame. The depth of the insertion slot 3a is slightly larger than the thickness of the insertion plate. When the insertion plate transfers the frame to the roller, the insertion plate is inserted into the insertion slot 3a, so that the frame is directly contacted and received by the roller. Then the insertion plate can be removed without contacting the frame, thereby effectively solving the problem of large sliding wear between the insertion plate and the frame when the insertion plate is removed, and the problem of gravity extrusion of the fruit in the frame when the frame falls after the insertion plate is removed. After the fruit is poured, the insertion plate can be inserted into the insertion slot 3a to smoothly unload the frame from the roller 3.
[0033] The principle of the present application is: when the fruit pouring operation is performed, the frame loaded with fruit is transferred from the cold storage to the outside of the turning frame 2 by the insertion plate of the forklift. Then the forklift moves linearly and makes the insertion plate correspond to the insertion slot 3a on the roller 3. After the frame is transferred to the upper side of the turning frame 2, the frame is contacted with the roller 3, and then the insertion plate is removed from the insertion slot 3a. Then the turning frame 2 and the frame are turned as a whole by the driving cylinder, and the fruit is gradually poured on the conveying belt. In this process, the baffle 4 and the corrugated plate 5 realize the blocking between the frame and the conveying belt to avoid the falling of the fruit. After the pouring is completed, the insertion plate is inserted into the insertion slot 3a to unload the frame, and waits for the transfer, turning and fruit pouring of the next frame.
[0034] The foregoing merely illustrates the principles of the application and application of its leading features. Various modifications and alterations to this application will become apparent to those skilled in the art in the light of the foregoing detailed description. It is our intention that within this detailed description there be read into as equivalents for each aspect of the application in which a change or alteration is suggested.
