Description

Technical Field

[0001] This utility model relates to the technical field of gantry return elevators, and in particular to an integrated gantry return elevator. Background Technology

[0002] In modern industrial production, logistics warehousing, and automated assembly, efficient and precise material transportation is crucial for ensuring production continuity, which is why gantry conveyors are widely used in material transportation scenarios.

[0003] The core structure of existing gantry conveyors typically includes a track frame extending along a preset trajectory, a movable conveying trolley, and a corresponding power system. However, existing gantry conveyors can only achieve single-line, unidirectional material transport and cannot directly meet the return requirements of empty loads or materials awaiting secondary processing. Currently, the industry commonly adopts a solution of setting up another set of identical equipment in parallel next to the original single-line gantry conveyor, with one set for forward transport and the other for reverse transport, thereby achieving the return of loads or materials. However, the parallel gantry conveyors greatly increase the space occupied, severely compressing the operation or storage area. At the same time, the parallel gantry conveyors also greatly increase the cost of material transport. Therefore, it is necessary to design an integrated gantry conveyor to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated gantry return elevator, which has the advantages of integrating material conveying and return processes, reducing space occupation and material conveying costs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an integrated gantry return elevator, comprising at least one set of parallel gantry conveyor return line modules and a double-layer lifting module symmetrically fixedly connected to both ends of the gantry conveyor return line modules along the conveying direction. The gantry conveyor return line module includes a gantry frame and a material conveying line and a tray return conveying line fixedly connected to the gantry frame in parallel along the vertical direction. The double-layer lifting module includes a first conveying line for conveying materials or empty trays and at least one set of second conveying lines for conveying empty trays or materials. The vertical distance between the first conveying line and the second conveying line is adjustable.

[0006] The present invention is further configured such that: the double-layer lifting assembly includes a lifting base and a vertical screw lifting slide fixedly connected to the lifting base in the vertical direction; the sliding end of the vertical screw lifting slide is fixedly connected to a lifting frame; the first conveyor line is fixedly connected to the top of the lifting frame; and the second conveyor line is movably connected to the lifting frame in the vertical direction based on the guide lifting adjustment assembly.

[0007] The present invention is further configured such that: the guide lifting adjustment assembly includes a vertical guide rail symmetrically and fixedly connected to the lifting frame along the vertical direction and a vertical lifting seat slidably connected to the vertical guide rail along the vertical direction; a lifting component that drives the vertical lifting seat to lift and lower is fixedly connected to the lifting frame along the vertical direction; and the second conveyor line is fixedly connected to the vertical lifting seat along the horizontal direction.

[0008] The present invention is further configured such that the lifting component uses a lifting electric cylinder.

[0009] The present invention is further configured such that: the adjacent gantry conveyor return line module and the double-layer lifting module are connected and fixed based on the mounting plate to realize the free combination between the gantry conveyor return line module and the double-layer lifting module.

[0010] The present invention is further configured such that: the bottom of the double-layer lifting module is evenly provided with a number of universal sliding wheels to realize the individual transfer of the double-layer lifting module or the overall transfer of the gantry return elevator.

[0011] The present invention is further configured such that: a plurality of first laser sensors for detecting the conveying status of materials or trays are fixedly connected at uniform intervals along the conveying direction of the material conveying line and the tray return conveying line; and second laser sensors for detecting the input or output status of materials or trays are fixedly connected at both ends of the first conveying line and the second conveying line along the conveying direction.

[0012] In summary, this utility model has the following beneficial effects: 1. The gantry conveyor return line module achieves simultaneous forward material conveying and reverse return of empty trays by setting parallel material conveying lines and tray return conveying lines along the vertical direction of the gantry frame. This eliminates the need for additional lateral space, significantly reducing space requirements. The integrated material conveying lines and tray return conveying lines also greatly reduce equipment operating costs. The double-layer lifting assembly uses a lifting frame on a vertical screw lifting slide with a first conveyor line at the top and at least one second conveyor line inside the lifting frame. On one hand, the first conveyor line connects with the material conveying line to achieve material conveying; on the other hand, the second conveyor line... By connecting with the material tray return conveyor line, the material tray can be returned and recycled, thus simultaneously realizing material feeding and material tray return, greatly improving work efficiency. On the other hand, by connecting the first and second conveyor lines simultaneously with the material conveyor line, or by connecting the first and second conveyor lines simultaneously with the material tray return conveyor line, multiple materials or material trays can be conveyed or returned at one time, further improving the material conveying efficiency or material tray return efficiency. At the same time, multiple sets of second conveyor lines can be set in the lifting frame at the same time, thus greatly increasing the material tray return efficiency while maintaining the material conveying efficiency. The adjustment method is flexible. 2. The adjacent gantry conveyor return line module and the double-layer lifting module are detachably connected and fixed through the mounting plate, so as to freely combine the number of modules and the arrangement according to the actual conveying needs, adapting to the conveying needs in different scenarios. At the same time, universal sliding wheels are set at the bottom of the double-layer lifting module to facilitate the individual transfer of the equipment or the overall position adjustment, improving the flexibility of equipment installation and layout adjustment.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Example: refer to Figures 1 to 3 An integrated gantry return elevator includes at least one set of parallel gantry conveyor return line modules 1 and double-layer lifting modules 2 symmetrically fixedly connected to both ends of the gantry conveyor return line modules 1 along the conveying direction. The gantry conveyor return line module 1 includes a gantry frame 11 and material conveying lines 12 and tray return conveying lines 13 fixedly connected to the gantry frame 11 in parallel along the vertical direction. This allows for simultaneous forward material conveying and reverse return of empty trays, eliminating the need for additional lateral space and significantly reducing space occupancy. The integrated material conveying lines... The double-layer lifting module 2 includes a first conveyor line 21 for conveying materials or empty trays and at least one set of second conveyor lines 22 for conveying empty trays or materials. The vertical distance between the first conveyor line 21 and the second conveyor line 22 is adjustable. The vertical distance between the first conveyor line 21 and the second conveyor line 22 is sufficient for a tray carrying materials to pass through. When multiple sets of second conveyor lines 22 are provided, the distance between adjacent second conveyor lines 22 remains fixed to achieve tray return. In this embodiment, only one set of the second conveyor line 22 is provided. By adjusting the vertical distance between the first conveyor line 21 and the second conveyor line 22, different conveying requirements can be adapted. On the one hand, the first conveyor line 21 is connected to the material conveyor line 12 to realize the conveying of materials, and the second conveyor line 22 is connected to the tray return conveyor line 13 to realize the return and recycling of trays. Thus, material feeding and tray return can be realized simultaneously, greatly improving work efficiency. On the other hand, the first conveyor line 21 and the second conveyor line 22 are connected to the material conveyor line 12 at the same time, or the first conveyor line 21 and the second conveyor line 22 are connected to the tray return conveyor line 13 at the same time, so that multiple materials or trays can be conveyed or returned at one time, further improving the material conveying efficiency or tray return efficiency. At the same time, multiple sets of second conveyor lines 22 can be set in the lifting frame 25 at the same time, so that the tray return efficiency can be greatly increased while maintaining the material conveying efficiency. The adjustment method is flexible.

[0017] refer to Figure 3Specifically, the double-layer lifting assembly includes a lifting base 23 and a vertical screw lifting slide 24 fixedly connected to the lifting base 23 in the vertical direction. A lifting frame 25 is fixedly connected to the sliding end of the vertical screw lifting slide 24. A first conveyor line 21 is fixedly connected to the top of the lifting frame 25. A second conveyor line 22 is movably connected to the lifting frame 25 in the vertical direction based on the guide lifting adjustment assembly 26. The lifting frame 25 is lifted and lowered by the vertical screw lifting slide 24, thereby lifting and lowering the first conveyor line 21 and the second conveyor line 22, thus realizing the loading and unloading of materials and trays. The guide lifting and adjusting assembly 26 includes a vertical guide rail 261 symmetrically fixedly connected to the lifting frame 25 along the vertical direction, and a vertical lifting seat 262 slidably connected to the vertical guide rail 261 along the vertical direction. A lifting component 263, which drives the vertical lifting seat 262 to rise and fall, is fixedly connected to the lifting frame 25 along the vertical direction. The second conveyor line 22 is fixedly connected to the vertical lifting seat 262 along the horizontal direction. The lifting component 263 drives the vertical lifting seat 262 and the second conveyor line 22 to rise and fall along the vertical guide rail 261, thereby adjusting the vertical distance between the first conveyor line 21 and the second conveyor line 22. In this embodiment, the lifting component 263 uses a lifting electric cylinder to precisely adjust the gap between the first conveyor line 21 and the second conveyor line 22. The lifting electric cylinder can also be coupled with the vertical screw lifting slide 24 to more flexibly adjust the material conveying and tray return mode.

[0018] refer to Figure 1 Specifically, the adjacent gantry conveyor return line module 1 and the double-layer lifting module 2 are connected and fixed based on the mounting plate 3 to achieve free combination between the gantry conveyor return line module 1 and the double-layer lifting module 2. The mounting plate 3 is fixed between the gantry conveyor return line module 1 and the double-layer lifting module 2 by welding or bolting. This allows for free combination of the number and arrangement of modules according to actual conveying needs, adapting to conveying requirements in different scenarios. Several universal sliding wheels 4 are evenly provided at the bottom of the double-layer lifting module 2 to realize the individual transfer of the double-layer lifting module 2 or the overall transfer of the gantry return elevator, improving the flexibility of equipment installation and layout adjustment.

[0019] refer to Figure 2Specifically, the material conveying line 12 and the tray return conveying line 13 are uniformly spaced and fixedly connected with several first laser sensors 5 for detecting the conveying status of materials or trays. The first conveying line 21 and the second conveying line 22 are fixedly connected at both ends along the conveying direction with second laser sensors 6 for detecting the input or output status of materials or trays. By using the first laser sensors 5 on the material conveying line 12 and the tray return conveying line 13, the conveying status of materials or trays can be detected in real time, and abnormalities such as jamming and deviation can be detected in time. By using the second laser sensors 6 at both ends of the first conveying line 21 and the second conveying line 22, the input and output status of materials or trays can be accurately monitored, ensuring smooth connection of the lifting and transfer process, and improving the accuracy and safety of the overall conveying operation.

[0020] Brief description of operating principle: The gantry conveyor return line module 1 achieves simultaneous forward material conveying and reverse return of empty trays by setting parallel material conveying lines 12 and tray return conveying lines 13 along the vertical direction on the gantry frame 11. The double-layer lifting assembly sets a lifting frame 25 on a vertical screw lifting slide 24, sets a first conveying line 21 on the top of the lifting frame 25, and sets at least one set of second conveying lines 22 inside the lifting frame 25. On the one hand, the first conveying line 21 connects with the material conveying line 12 to realize material conveying, and the second conveying line 22 connects with the tray return conveying line 13 to realize tray return. The reflux and recycling system enables simultaneous material feeding and tray return, significantly improving work efficiency. Furthermore, by connecting the first conveyor line 21 and the second conveyor line 22 to the material conveyor line 12, or by connecting the first conveyor line 21 and the second conveyor line 22 to the tray return conveyor line 13, multiple materials or trays can be conveyed or returned at once, further improving material conveying efficiency or tray return efficiency. Additionally, multiple sets of second conveyor lines 22 can be installed within the lifting frame 25, thereby greatly increasing tray return efficiency while maintaining material conveying efficiency.
