Description

Technical Field

[0001] This utility model relates to the field of high-stability loading and unloading devices, specifically a high-stability loading and unloading device for cargo loading equipment. Background Technology

[0002] The cargo loading equipment includes a gantry that can move between the cargo and the carriage, a rotating gantry structure that is driven to rotate by a rotating drive device on top of the gantry, and a pick-and-place device installed on the rotating gantry structure and driven to lift and swing by the drive device. The pick-and-place device is used to pick up the cargo, transport it into the carriage, and then place the cargo inside.

[0003] For loading in the cotton yarn industry, several material arrays are packaged side-by-side into a single material bag during production. When loading this type of material, a single-layer forklift can be used to pick up several bags row by row and stack them layer by layer. This method offers high stability but low efficiency. Alternatively, a multi-layer forklift can be used to pick up several layers of material bags, then reverse and push the bags down using a pusher plate, loading them row by row. This significantly improves loading efficiency. However, to ensure the forks can handle the multiple layers of material bags on the rack and prevent damage to lower layers, further adjustments are needed. The spacing between the forks in several layers causes some of the material bags to deform and bend downwards when unloading. This results in excessive forward and backward displacement of the material bags after they have completely fallen, and the falling position is also affected by the height difference between them. This increases the probability that the loaded material bags will be skewed, stacked unevenly, or stacked on one side of the same layer, making it difficult to place the material of the upper layer evenly. Once these situations occur, the machine needs to be stopped for manual adjustment, which greatly affects the loading effect and stability of the material bags and reduces loading efficiency.

[0004] The research objective of this utility model is to design a highly stable loading and unloading device for cargo loading equipment, addressing the problems existing in the prior art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a highly stable loading and unloading device for cargo loading equipment, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A highly stable loading and unloading device for cargo loading equipment includes:

[0008] A pick-and-place rack is used to connect the corresponding loading equipment. The pick-and-place rack is equipped with a movable drive device and a material unloading drive device.

[0009] Several picking layers are installed on one side of the picking and placing rack. The movable driving device is used to drive the multiple picking layers to move up and down to adjust the vertical distance between the multiple picking layers. When placing goods, the vertical distance between the multiple picking layers is adjusted to be reduced.

[0010] The unloading component is located on one side of the pick-up and place rack and corresponds to several of the pick-up layers. The unloading drive device is used to drive the unloading component to push the materials on several of the pick-up layers away from the several pick-up layers when placing the goods.

[0011] Furthermore, the plurality of the picking layers include at least one fixed layer fixedly installed on one side of the picking rack, and at least two movable layers movably installed on one side of the picking rack. The movable driving device is used to drive the movable layers to move up and down to adjust the vertical distance between the movable layers and between the movable layers and the fixed layer.

[0012] Furthermore, the number of fixed layers is set to one, and the number of movable layers is set to two and symmetrically distributed on the upper and lower sides of the fixed layer. The movable driving device is a screw driving device, and the two driving ends are respectively used to drive the two movable layers to move towards each other or in opposite directions. When unloading, the two movable layers move towards each other until the vertical distance between the fixed layer and the two movable layers is reduced, forming two guide channels for vertically limiting and guiding the material unloading.

[0013] Furthermore, the pick-and-place rack includes a connecting frame for connecting the loading equipment, a fixed frame installed on one side of the connecting frame, and two movable frames symmetrically located on the upper and lower sides of the fixed frame and slidably connected to the connecting frame via a slider and a slide rail. The fixed layer includes several fixed inserts installed laterally at intervals in the middle of one side of the fixed frame. The two movable layers are respectively installed on one side of the movable frame, and each movable layer includes several movable inserts arranged laterally at intervals. The movable drive device includes a housing on the other side of the connecting frame, a synchronous lead screw in the housing, a lead screw motor on the top of the housing for driving the synchronous lead screw to rotate, and a sliding seat slidably disposed on one side of the housing and respectively connected to the two movable frames.

[0014] Furthermore, the unloading drive device includes a telescopic motor mounted on the connecting frame, a telescopic frame that is laterally slidably connected to the loading equipment via a slider and a slide rail and has a support extending downward at one end, and the unloading component is a unloading frame mounted on one side of the support, the unloading frame including at least three push rods that are laterally corresponding to the top of one fixed layer and two movable layers respectively.

[0015] Furthermore, a plurality of inclined first braces are vertically arranged and fixed between the support and the telescopic frame, and a plurality of inclined second braces are vertically arranged and fixed between the connecting frame and the loading equipment.

[0016] Furthermore, the left and right sides of the two movable frames are respectively connected to the connecting frame by sliders and slide rails to form two vertical sliding lines symmetrical about the central axis of the connecting frame. The housing is located on the side of the other side of the connecting frame and between the two vertical sliding lines. The telescopic motor is located in the middle of the other side of the connecting frame.

[0017] Furthermore, the fixed frame is provided with vertically extending limiting posts on both sides, and the two movable frames are provided with limiting bosses corresponding to the upper and lower ends of the limiting posts at both ends. The movable driving device drives the two movable layers to move towards each other until the limiting bosses of the two movable frames abut against the two limiting posts and are then restricted.

[0018] Furthermore, a fixing rod for installing the fixing layer is connected between the middle parts of the two limiting posts. The upper and lower sides of both ends of the fixing rod are perpendicular to the two limiting posts and are provided with triangular reinforcing ribs.

[0019] Therefore, the beneficial effects of this utility model are:

[0020] 1. By configuring several picking layers that move up and down driven by a moving drive device, the picking and placing device, when applied to loading in the cotton lap yarn industry, can achieve the following functions: During picking, the vertical distance between the picking layers can be increased, thereby improving picking efficiency by picking multiple layers of material bags at once while avoiding damage to the material bags below them; during placing, the vertical distance between the picking layers and the material bags can be reduced until the gap is above the material bags, allowing adjacent picking layers to be vertically limited during the falling of the material bags to prevent deformation. The downward curve of the material bag prevents excessive forward and backward displacement after the bag has completely fallen. The feeding mechanism simultaneously pushes materials from several layers of bags to be fed, ensuring a stable and neat stack after the bags have been fed. This prevents the bags from shifting due to height differences between layers, avoiding misalignment, uneven stacking, or bags from the same layer stacking on one side, thus improving the stability of the feeding device and ultimately enhancing the loading efficiency and effectiveness of the loading equipment.

[0021] 2. By dividing several picking layers into fixed layers and movable layers, the spacing between several picking layers can be adjusted simply by driving the movable layer up and down through the movable drive device. This reduces the number of picking layers that the movable drive device needs to drive, reduces the drive burden, thereby reducing drive costs, and also reduces the weight of the picking and placing device, thus reducing the overall drive cost of the loading equipment.

[0022] 3. Under the premise of simultaneously picking up and placing materials from three layers of three picking layers to improve loading efficiency, the vertical distance between the three picking layers is adjusted by synchronously driving two movable layers to move in opposite directions or in the opposite direction through a screw drive device, thereby minimizing the driving cost of the movable drive device.

[0023] 4. By setting the fixed layer and the movable layer as several fixed insertion rods and several movable insertion rods respectively, when picking up goods from several picking layers, the fixed insertion rods and movable insertion rods can be inserted into the multi-layer comb-tooth shelf respectively, and then lifted up to lift several layers of cotton rolls to complete the picking and handling. This greatly improves the convenience of picking up goods from several picking layers, and the insertion rods will not damage the material bags during the picking process.

[0024] 5. By adding a support unit, the support strength of the telescopic frame to the material feeding frame is improved, thereby improving the stability of the material feeding rod pushing the material above the fixed layer and the movable layer, which improves the driving stability of the material feeding drive device, and thus improves the stability when several layers of material bags are lowered.

[0025] 6. By adding the first and second diagonal braces, the structural stability of the connection between the support and the telescopic frame, and between the connecting frame and the mounting frame 7, is improved, thereby improving the structural stability of the material feeding drive device and the structural stability of the pick-and-place frame.

[0026] 7. By setting up two upper and lower sliding lines to ensure the stability of the upper and lower sliding of the two movable frames, the housing of the screw drive device is installed laterally to make way for the installation of the telescopic motor. This ensures the stability of the telescopic motor driving the telescopic frame to move laterally, and allows the screw drive device and the telescopic motor to be installed on the same mounting level, improving the structural compactness of the picking and placing device.

[0027] 8. By adding limiting posts and limiting bosses, the excessive movement of the two moving layers towards each other can be prevented from causing the vertical distance between them and the fixed layer to be too small, which could squeeze and damage the material inside, or cause the material to be damaged by excessive friction when it is being fed. This improves the safety and stability of the movement of the two moving layers towards each other. Attached Figure Description

[0034] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0035] A highly stable loading and unloading device for cargo loading equipment:

[0036] refer to Figure 1 The cargo loading equipment includes:

[0037] The lifting drive mechanism 6 is driven to move laterally by the gantry frame;

[0038] Mounting frame 7 is equipped with a rotary drive mechanism 8 and is located below the transverse frame. The two ends of the mounting frame 7 are respectively rotatably connected to a first linkage mechanism 61 and a second linkage mechanism 62. The first linkage mechanism 61 and the second linkage mechanism 62 extend upward and are respectively driven by the lifting drive mechanism 6 to move up and down.

[0039] The lifting drive mechanism 6 is used to drive the first linkage mechanism 61 and the second linkage mechanism 62 to move in the same direction, thereby driving the mounting frame 7 to move up and down; or, it can drive the first linkage mechanism 61 and the second linkage mechanism 62 to move in opposite directions or one of them to drive the mounting frame 7 to swing to an inclined position. For the specific structure of the cargo loading equipment, please refer to the prior patent application entitled "An Automatic Cargo Loading Equipment," application number 202411344605.2.

[0040] refer to Figure 2-6 The picking and placing device includes:

[0041] The pick-and-place frame 1 is used to connect the mounting frame 7. The pick-and-place frame 1 is equipped with a movable drive device 4 and a feeding drive device 5.

[0042] A plurality of picking layers 2 are installed on one side of the picking rack 1. The movable driving device 4 is used to drive the plurality of picking layers 2 to move up and down to adjust the vertical distance between the plurality of picking layers 2. When unloading, the vertical distance between the plurality of picking layers 2 is adjusted to reduce the setting.

[0043] The unloading component 3 is located on one side of the pick-up and place rack 1 and corresponds to several of the picking layers 2. The unloading drive device 5 is used to drive the unloading component 3 to push the materials on several of the picking layers 2 out of the several picking layers 2 during unloading.

[0044] The above structure, through the arrangement of several picking layers 2 driven up and down by the active drive device 4, enables the picking and placing device to achieve the following functions when used in the cotton roll yarn industry for loading: During picking, the vertical distance between the picking layers 2 can be increased, thereby improving picking efficiency by picking several layers of material bags at once while avoiding damage to the material bags below them; during placing, the vertical distance between the picking layers 2 and the material bags can be reduced until the gap is above the material bags, allowing adjacent picking layers 2 to be vertically limited during the falling of the material bags. To prevent deformation and bending, thus avoiding excessive forward and backward displacement after the material bags have completely fallen, the feeding component 3 pushes the materials on several picking layers 2 to be fed simultaneously. This ensures that after several layers of material bags are fed, they can be stably stacked into a neat stack. This prevents the falling position of several layers of material bags from being affected by the height difference between them, thus avoiding situations where the material bags are skewed, not stacked neatly, or stacked on one side of the same layer, causing the material of the upper layer to not be placed evenly. This improves the stability of the picking and placing device, thereby improving the loading effect and efficiency of the loading equipment.

[0045] To reduce the driving cost of the movable drive device 4, the plurality of picking layers 2 include at least one fixed layer 22 fixedly installed on one side of the picking rack 1 and at least two movable layers 23 vertically movably installed on one side of the picking rack 1. The movable drive device 4 is used to drive the movable layers 23 to move up and down, thereby adjusting the vertical distance between the movable layers 23 and between the movable layers 23 and the fixed layer 22. This structure, by dividing the plurality of picking layers 2 into fixed layers 22 and movable layers 23, allows the distance between the plurality of picking layers 2 to be adjusted simply by driving the movable layers 23 vertically through the movable drive device 4. This reduces the number of picking layers 2 that the movable drive device 4 needs to drive, reduces the driving burden, thereby reducing the driving cost, and also reduces the weight of the picking device, thus reducing the overall driving cost of the loading equipment.

[0046] Preferably, the fixed layer 22 is one, and the movable layers 23 are two, symmetrically distributed on the upper and lower sides of the fixed layer 22. The movable drive device 4 is a screw drive device, and the two drive ends are used to drive the two movable layers 23 to move towards each other or in opposite directions. When unloading, the two movable layers 23 move towards each other until the vertical distance between the fixed layer 22 and the two movable layers 23 is reduced, forming two guide channels 21 for vertically limiting and guiding the material unloading. Thus, while simultaneously picking up and placing three layers of materials through three picking layers 2 to improve loading efficiency, the vertical distance between the three picking layers 2 is adjusted by synchronously driving the two movable layers 23 to move towards each other or in opposite directions through the screw drive device, minimizing the driving cost of the movable drive device 4. Furthermore, when unloading, the guide channels 21 can limit the material bag's vertical movement during its descent to prevent deformation and bending, improving the stability of the material bag unloading and loading.

[0047] To facilitate the retrieval of material bags by several retrieval layers 2, the retrieval rack 1 includes a connecting rack 11 for connecting the loading equipment, a fixed rack 12 installed on one side of the connecting rack 11, and two movable racks 13 symmetrically located above and below the fixed rack 12 and connected to the connecting rack 11 by sliders and slide rails. Specifically, the connecting rack 11 is connected to the lower part of the mounting rack 7. The fixed layer 22 includes several fixed inserts 221 installed horizontally at intervals in the middle of one side of the fixed rack 12. The two movable layers 23 are respectively installed on one side of the movable rack 13, and each movable layer 23 includes several movable inserts 231 arranged horizontally at intervals. The movable drive device 4 includes a housing 41 located on the other side of the connecting rack 11, a synchronous lead screw located in the housing 41, a lead screw motor 42 located on the top of the housing 41 and used to drive the synchronous lead screw to rotate, and a sliding seat 43 slidably located on one side of the housing 41 and respectively connected to the two movable racks 13. By setting the fixed layer 22 and the movable layer 23 as a number of fixed insert rods 221 and a number of movable insert rods 231 respectively, when picking up goods from the multiple picking layers 2, the fixed insert rods 221 and the movable insert rods 231 can be inserted into the multi-layer comb rack respectively, and then lifted up to lift the multiple layers of cotton rolls to complete the picking and handling, which greatly improves the convenience of picking up goods from the multiple picking layers 2, and the insert rods will not damage the material bags during the picking process.

[0048] To improve the driving stability of the feeding drive device 5, the feeding drive device 5 includes a telescopic motor 51 mounted on the connecting frame 11, and a telescopic frame 52 that is laterally slidably connected to the mounting frame 7 via a slider and a slide rail, and has a support portion 521 extending downward at one end. The feeding component 3 is a feeding frame mounted on one side of the support portion 521. The feeding frame includes at least three push rods 31 that are laterally positioned above one fixed layer 22 and two movable layers 23, respectively. By adding the support portion 521, the support strength of the telescopic frame 52 on the feeding frame is increased, thereby improving the stability of the push rods 31 pushing the material above the fixed layer 22 and movable layer 23, thus improving the driving stability of the feeding drive device 5, and consequently improving the stability when several layers of material bags are lowered.

[0049] To improve the structural stability of the unloading drive device 5 and the pick-and-place frame 1, a plurality of inclined first braces 522 are vertically arranged and fixed between the support part 521 and the telescopic frame 52, and a plurality of inclined second braces 111 are vertically arranged and fixed between the connecting frame 11 and the mounting frame 7. Thus, by adding the first braces 522 and the second braces 111, the structural stability of the connection between the support part 521 and the telescopic frame 52, and between the connecting frame 11 and the mounting frame 7, is improved, thereby enhancing the structural stability of the unloading drive device 5 and the pick-and-place frame 1.

[0050] To improve the structural compactness of the pick-and-place device, the left and right sides of the two movable frames 13 are respectively connected to the connecting frame 11 by sliders and slide rails, forming two vertical sliding lines 131 symmetrical about the central axis of the connecting frame 11. The housing 41 is located on the side of the other side of the connecting frame 11 and between the two vertical sliding lines 131. The telescopic motor 51 is located in the middle of the other side of the connecting frame 11. This structure, by ensuring the vertical sliding stability of the two movable frames 13 through the arrangement of the two vertical sliding lines 131, allows the housing 41 of the screw drive device to be installed laterally to make room for the installation of the telescopic motor 51. This ensures the lateral stability of the telescopic motor 51 driving the telescopic frame 52 and allows the screw drive device and the telescopic motor 51 to be installed on the same mounting surface, improving the structural compactness of the pick-and-place device.

[0051] To improve the safety of the two movable layers 23 moving towards each other, the fixed frame 12 is provided with vertically extending limiting posts 121 on both sides, and the two movable frames 13 are provided with limiting bosses 132 at both ends corresponding to the upper and lower ends of the limiting posts 121. The movable drive device 4 drives the two movable layers 23 to move towards each other until the limiting bosses 132 of the two movable frames 13 abut against the two limiting posts 121 and are then restricted. Thus, by adding the limiting posts 121 and limiting bosses 132, the vertical distance between the two movable layers 23 and the fixed layer 22 is prevented from being too small due to excessive movement towards each other, which could crush and damage the material therein, or cause the material to be damaged by excessive friction during material feeding. This improves the safety and stability of the two movable layers 23 moving towards each other.

[0052] To improve the structural strength of the fixing frame 12, a fixing rod 122 for installing the fixing layer 22 is connected between the middle of the two limiting posts 121. The upper and lower sides of the two ends of the fixing rod 122 are perpendicular to the two limiting posts 121 and are provided with triangular reinforcing ribs 123.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
