Description

Technical Field

[0001] The utility model belongs to the field of elevators, and in particular relates to an elevator with a box-unpacking structure. Background Art

[0002] With the vigorous development of the warehousing and logistics industry, the demand for improving the efficiency of goods storage and retrieval and reducing goods loss has become an important driving force for the development of the industry. As an indispensable key equipment in the warehousing system, the stability of the performance and the accuracy of the operation of the elevator directly affect the operating efficiency and safety of the entire logistics system. Especially when dealing with multiple vertically stacked boxes, the challenge is even more severe. How to ensure the fast and accurate placement of the target box while avoiding unnecessary interference with other boxes has become a technical problem that needs to be solved in the field of warehousing and logistics.

[0003] In the current warehousing system, when multiple boxes are stacked vertically in a single cargo space, a shuttle car and a hoist are usually used to work together to remove the target box. The shuttle car first transports the boxes stacked vertically in the cargo space to the transfer platform, and then the loading platform reaches the height of the target box through the lifting mechanism and docks with the transfer platform. The telescopic fork on the loading platform is controlled to reach the location of the target box, and then the target box is grabbed and placed on the loading platform.

[0004] However, when the telescopic fork grabs the target box, the friction between the target box and the box below it often causes the lower box to be accidentally dragged. This dragging may not only cause the position of other boxes to shift, resulting in unnecessary displacement, increasing the complexity and cost of system maintenance, but also may cause a series of potential safety risks, such as box collapse and collision, which seriously threatens the overall stability and safety of the storage system.

[0005] In addition, this unexpected dragging may also have a negative impact on other equipment in the storage system. When handling accidentally dragged boxes, shuttles, conveyor belts and other equipment may be subject to additional loads and wear, which will shorten the service life of the equipment, increase the frequency of repairs and replacements, and further increase the operating costs of the storage system. Especially when handling valuable or fragile items, this potential risk places extremely high demands on the safety and reliability of the storage system. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a hoist with a box unloading structure. By arranging an abutment mechanism at the end of the cargo platform, when grabbing the upper material box, the abutment mechanism is used to abut the lower material box, thereby avoiding the movement of the lower material box and enhancing the stability and safety of the storage system.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A lifting machine with a box unloading structure comprises a frame, a lifting mechanism and a cargo platform, wherein the cargo platform is provided with a telescopic cargo pickup mechanism and an abutment mechanism, wherein the abutment mechanism is used to abut against a lower material box when the telescopic cargo pickup mechanism grabs an upper material box.

[0009] Furthermore, the abutment mechanism includes a flip plate hinged to the end of the cargo platform and a first driving mechanism for driving the flip plate to flip.

[0010] Furthermore, the flip plate is flipped upside down or left side to left side.

[0011] Furthermore, the abutment mechanism includes a telescopic plate slidably arranged at the end of the cargo platform and a second driving mechanism for driving the telescopic plate to slide left and right along the cargo platform.

[0012] Furthermore, one or more conveying rollers are provided on the flip plate, and the conveying rollers are powered conveying rollers or unpowered conveying rollers.

[0013] Furthermore, a cargo platform mounting seat is provided at the lower part of the cargo platform, and the cargo platform and the cargo platform mounting seat constitute a contact mechanism. The cargo platform is slidably set on the cargo platform mounting seat through a sliding drive mechanism, and the cargo platform slides left and right along the cargo platform mounting seat, so that the end of the cargo platform can support the lower material box when the telescopic picking mechanism grabs the upper material box.

[0014] Furthermore, the rack adopts a column type structure or a frame type structure. When the rack adopts a column type structure, the column type structure includes but is not limited to a single column structure and a multi-column structure.

[0015] Furthermore, the cargo platform includes but is not limited to a flat plate structure, a roller structure, a synchronous belt structure and a chain structure.

[0016] Furthermore, the cargo platform includes a single row of rollers or multiple rows of rollers, and the single row of rollers or multiple rows of rollers are powered rollers or non-powered roller structures. When the cargo platform includes multiple rows of rollers, an abutment mechanism is provided at the end of at least one row of rollers.

[0017] Furthermore, the cargo platform includes at least two rows of support structures arranged at intervals, and the distance between the at least two rows of support structures arranged at intervals is adjustable. The support structures include but are not limited to flat plate structures, roller structures, conveyor belt structures and conveyor chain structures.

[0018] Furthermore, the telescopic cargo-picking mechanism is a fork-holding structure, an adsorption structure, a clamping structure, or a combination of multiple structures.

[0019] The beneficial effects of the utility model are:

[0020] 1) The utility model provides an abutment mechanism at the end of the cargo platform. When grabbing the upper material box, the abutment mechanism is used to abut the lower material box, thereby preventing the lower material box from moving and enhancing the stability and safety of the storage system.

[0021] 2) By setting a conveying roller on the flip plate, it is helpful to reduce the friction between the material box and the flip plate, ensuring the smoothness of the movement of the material box to the loading platform. When the conveying roller adopts a powered conveying roller, it is helpful to reduce the force on the telescopic pickup mechanism and reduce the deformation of the telescopic pickup mechanism, especially when conveying heavy material boxes, thereby extending the service life of the telescopic pickup mechanism.

[0022] 3) When the cargo platform adopts at least two rows of supporting structures, the distance between the at least two rows of supporting structures arranged at intervals is adjustable, which is suitable for material boxes of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the attached Figure 1-Figure 4, clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example 1

[0034] like Figure 1 As shown, a lifting machine with a box unloading structure includes a frame 1, a lifting mechanism 2 and a cargo platform 3, wherein the lifting mechanism 2 is installed on the frame 1. Figure 3 As shown, a telescopic picking mechanism 31 is provided on the cargo platform 3, and a butt mechanism 32 is provided at the end of the cargo platform 3. The butt mechanism 32 is used to butt against the lower material box when the telescopic picking mechanism 31 grabs the upper material box, thereby avoiding the movement of the lower material box and enhancing the stability and safety of the warehousing system.

[0035] like Figure 2 As shown, the abutment mechanism 32 includes a flip plate 321 hinged to the end of the conveying mechanism 33 and a first driving mechanism (not shown in the figure) for driving the flip plate to flip. When grabbing the upper material box, the first driving mechanism drives the flip plate 321 to flip to the end of the loading platform, so that the upper surface of the flip plate 321 is flush with the upper surface of the lower material box, and the end of the flip plate 321 abuts against the side wall of the lower material box, thereby preventing the lower material box from moving and enhancing the stability and safety of the storage system.

[0036] In some working environments, the flip plate 321 of the abutment mechanism 32 can also reduce the gap between the cargo platform 3 and the shelf or the transfer platform 4 to ensure the smooth movement of the material box.

[0037] like Figure 2As shown, in the present embodiment, the flip plate 321 flips up and down, and both sides of the flip plate 321 are hinged to the end of the cargo platform 3. The first driving mechanism includes but is not limited to a motor and a cylinder + rack and pinion mechanism. When the driving mechanism adopts a motor, the motor is horizontally installed on one side of the cargo platform, and the output shaft of the motor is fixedly connected to the flip plate 321. When the motor rotates, it drives the flip plate 321 to flip around its hinge point; when the first driving mechanism adopts a cylinder + rack and pinion mechanism, the rack is fixedly connected to the piston rod of the cylinder, the gear is connected to the flip plate 321, and the gear is meshed with the rack. When the cylinder is extended or retracted, the rack drives the gear to rotate, thereby realizing the flipping function of the flip plate 321.

[0038] like Figure 2 As shown, a conveying roller 322 is provided on the flip plate 321 , which is beneficial to reducing the friction between the material box and the flip plate 321 and ensuring the smoothness of the movement of the material box to the cargo platform 3 .

[0039] In other embodiments, the conveying roller 322 is only disposed at the end of the flip plate 321 , or a plurality of conveying rollers 322 are disposed on the flip plate 321 .

[0040] In some embodiments, the conveying roller 322 adopts an unpowered conveying roller or a powered conveying roller. When a powered conveying roller is adopted, it is beneficial to reduce the force on the telescopic picking mechanism 31 and reduce the deformation of the telescopic picking mechanism 31, especially when conveying heavy weight boxes, thereby extending the service life of the telescopic picking mechanism 31.

[0041] In some embodiments, the rack 1 may adopt a column structure or a frame structure. When the rack 1 adopts a column structure, the column structure includes but is not limited to a single column structure and a multi-column structure.

[0042] In some embodiments, the cargo platform 3 includes but is not limited to a flat plate structure, a roller structure, a synchronous belt structure and a chain structure. When the cargo platform 3 adopts a roller structure, the roller adopts an unpowered roller or a powered roller.

[0043] In this embodiment, the cargo platform 3 adopts a roller structure, such as Figure 1 As shown, the cargo platform 3 includes two rows of rollers spaced apart, and the spacing between the two rows of rollers spaced apart is adjustable to accommodate material boxes of different sizes, and the spacing adjustment forms include but are not limited to a screw centering adjustment mechanism and a cylinder adjustment.

[0044] In some embodiments, the rollers, transmission belts or transmission chains on one side are fixed, and the rollers, transmission belts or transmission chains on the opposite side are movable. The spacing adjustment mechanism drives the movable rollers, transmission belts or transmission chains to move closer to or away from the fixed rollers, transmission belts or transmission chains to adjust the spacing of the cargo platform 3.

[0045] In other embodiments, the rollers, transmission belts or transmission chains on both sides are movable, and the spacing adjustment mechanism drives the rollers, transmission belts or transmission chains on both sides to move closer to or away from each other, thereby adjusting the spacing of the cargo platform 3.

[0046] like Figure 1 As shown, the abutment mechanism 32 is only provided at one end of the cargo platform 3, or the abutment mechanism 32 is provided at both ends of the cargo platform 3. When the abutment mechanism 32 is provided at both ends of the cargo platform 3, claws are provided at both ends of the telescopic picking-up mechanism 31, and the telescopic picking-up mechanism 31 can be telescoped to both sides of the cargo platform 3. The abutment mechanism 32 is provided at both ends of the cargo platform 3, which is beneficial for the cargo platform 3 to realize unpacking and picking up goods at both ends.

[0047] In some embodiments, the claw is a telescopic claw or a swinging claw. When the claw is a telescopic claw, the telescopic claw is a component with a telescopic function, such as an electromagnetic telescopic rod, an electric push rod, etc.; when the claw is a swinging claw, the swinging claw is rotationally connected to the telescopic pickup mechanism 31, and the swinging claw is driven to rotate by a motor + gear, or other rotation driving methods are used.

[0048] Example 2

[0049] The difference from Example 1 is that Figure 3 As shown, in this embodiment, the cargo platform 3 adopts a single-row roller structure.

[0050] Example 3

[0051] The difference from Example 1 is that Figure 5 As shown, the flip plate 321 flips horizontally, one side of the flip plate 321 is hinged to the end of the cargo platform 3, and the other side of the flip plate 321 is a free end. The first driving mechanism is connected to the hinge axis of the flip plate 321. When the first driving mechanism rotates, it drives the flip plate 321 to flip horizontally around its hinge point, thereby realizing the flipping function of the flip plate 321.

[0052] Example 4

[0053] The difference from Example 1 is that Figure 6 As shown, the abutment mechanism 32 includes a telescopic plate 33 slidably arranged at the end of the cargo platform 3 and a second driving mechanism for driving the telescopic plate 33 to slide left and right along the cargo platform 3. When the second driving mechanism drives the telescopic plate 33 to extend along the cargo platform, the telescopic plate forms an abutment mechanism to realize the unpacking action of loading and unloading boxes.

[0054] Example 5

[0055] The difference from Example 1 is that Figure 7As shown, a cargo platform mounting seat 34 is provided at the lower portion of the cargo platform 3, and the cargo platform 3 and the cargo platform mounting seat 34 constitute a contact mechanism. The cargo platform 3 is slidably set on the cargo platform mounting seat 34 through a sliding drive mechanism, and the cargo platform 34 slides left and right along the cargo platform mounting seat 34, so that the end of the cargo platform 3 can support the lower material box when the telescopic picking mechanism 31 grabs the upper material box.

[0056] When the hoist is used to grab the topmost material box in the vertical stack, the shuttle car moves the stacked material box and places it on the transfer platform 4, and the lifting mechanism 2 lifts the cargo platform 3 to the height of the target material box. Figure 4 As shown, the abutting mechanism 32 is in motion, and the front end of the abutting mechanism 32 is used to abut the lower material box, and then the telescopic picking mechanism 31 on both sides of the cargo platform 3 is controlled to extend toward the target material box. After the telescopic picking mechanism 31 is extended to the right position, the target material box is grabbed, and then the telescopic picking mechanism 31 is controlled to retract toward the cargo platform 3. At this time, the target material box moves toward the cargo platform 3 together with the telescopic picking mechanism 31 under the action of the telescopic picking mechanism 31, until the target material box is completely grabbed onto the cargo platform 3, and then the abutting mechanism 32 is reset; during the grabbing process of the target material box, the movement of the lower material box is avoided under the resisting action of the abutting mechanism 32, thereby enhancing the stability and safety of the storage system. After completing the handling of the material box, the abutting mechanism 32 is retracted to prevent the cargo platform from interfering with the handover platform during the lifting process.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
