Description

Technical Field

[0001] The utility model relates to a paper loading device, in particular to an adjustable manual palletizing paper loading device. Background Art

[0002] An operator stands on a platform and places a paper stack on the paper loading platform from the rear side of the paper loading platform, aligns it with a reference line located on the front side of the paper loading platform and stacks it up for a paper picking suction nozzle to pick. When the paper size is too small, the operator needs to lean forward to align the paper stack with the reference line on the front side of the paper loading platform, and it is very inconvenient to place the paper. Without adjusting the paper picking suction nozzle, the structure is optimized to facilitate the operator to place the paper. Content of the Utility Model

[0003] In view of the technical problems existing in the background art, the utility model aims to provide an adjustable manual palletizing paper loading device, which moves the platform and opens a gap on the palletizing paper loading platform for the platform to enter or exit, so as to adapt to the placement of papers with different specifications.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: The adjustable manual palletizing paper loading device includes a palletizing paper loading platform and a platform. The palletizing paper loading platform is arranged to be lifted and lowered. The palletizing paper loading platform has a supporting area, and the platform has a standing surface. Among them, the platform is arranged to move back and forth. There is a gap on the rear side of the palletizing paper loading platform for the platform to enter and exit. The gap corresponds to a non-supporting area. The supporting area and the non-supporting area together form a paper supporting surface. The platform moves based on the front edge of the paper supporting surface to adjust the overlapping area in the up and down directions between the standing surface and the paper supporting surface.

[0005] In this solution, based on the front edge of the paper supporting surface, when the paper size becomes larger, the platform moves backward to exit the gap. When the paper size becomes smaller, the platform moves forward to enter the gap. Without changing the reference line, the position of the platform is adjusted to facilitate the operator to place the paper. The lifting and lowering of the palletizing paper loading platform can adjust the height of the upper surface of the paper stack, which is convenient for palletizing.

[0006] Preferably, the platform is installed on a mounting frame. Multiple levels of steps are sequentially arranged on the mounting frame. The height of the steps gradually decreases from front to back. A guardrail is arranged circumferentially around the platform.

[0007] In this solution, the arrangement of multiple levels of steps facilitates the operator to board the platform, and the guardrail can protect the operator during the paper placing process.

[0008] Preferably, the gap is located in the middle of the palletizing paper loading platform, and the supporting area is in a "U" shape.

[0009] In this solution, the gap is arranged in the middle, so that the paper can span across the non-supporting area and is stably supported on both the left and right sides.

[0010] Preferably, the paper stacking platform is lifted and mounted on the mounting platform, and the front side of the mounting frame is provided with casters, which are in rolling contact with the mounting platform.

[0011] In this design, the casters make rolling contact with the mounting platform, allowing the mounting bracket to be supported by the platform via the casters, and making adjustment convenient.

[0012] Preferably, the mounting bracket has a rack on its lower side, the rack meshing with a gear, and the gear being connected to a power source for transmission.

[0013] In this design, the power source drives the mounting frame to move back and forth through the meshing of gears and racks, and the structure is stable after adjustment.

[0014] Preferably, the mounting bracket has a slider on its rear side, and the slider is slidably mounted on a slide rail.

[0015] In this design, the mounting bracket is supported by a slide rail via a slider, and the slide rail guides the forward and backward movement of the mounting bracket via the slider.

[0016] Preferably, a linkage assembly connects the mounting platform and the paper stacking platform. The linkage assembly is symmetrically arranged on the left and right sides of the mounting platform. The linkage assembly includes a first link and a second link. The middle part of the first link is hinged to the middle part of the second link. The front end of the first link is hinged to the paper stacking platform. The rear end of the first link is in rolling contact with the mounting platform. The front end of the second link is hinged to the mounting platform. The rear end of the second link is in rolling contact with the paper stacking platform. A cylinder is hinged to the front part of the second link. The cylinder is connected to a drive block. The drive block is hinged to the front part of the first link.

[0017] In this design, the cylinder opens or closes the first and second connecting rods via a drive block, thereby raising and lowering the paper stacking platform, which facilitates stacking by operators.

[0018] Preferably, the non-supported area is provided with a support for forward and backward movement adjustment.

[0019] In this solution, for large sheets of paper, additional support is provided in the middle to prevent the paper stack from collapsing in the middle. For small sheets of paper, additional support is provided for sheets of paper that fall into the unsupported area on one side to prevent the paper stack from sagging on one side.

[0020] Preferably, the paper stacking platform is provided with a support plate for supporting the support. The support plate is located on the left and right sides of the non-support area. The support plate is equipped with a limiting plate for limiting the backward movement of the support. The distance between the support plates is greater than the width of the platform.

[0021] In this scheme, the support plate supports the barrier, and the limiting plate restricts the barrier from moving backward. The adjustment structure is simple, and the distance between the support plates is greater than the width of the platform to avoid mutual interference.

[0022] Preferably, the support plate is provided with adjustment holes arranged along the front-to-back direction for mounting the limiting plate, and the limiting plate is provided with mounting holes.

[0023] In this solution, the position of the limiting plate is adjusted by fastening the mounting holes to the corresponding adjustment holes, thereby achieving the purpose of adjusting the support.

[0024] The beneficial effects of this utility model are as follows: using the front edge of the paper tray as a reference, when the paper size increases, the platform moves backward out of the gap; when the paper size decreases, the platform moves forward into the gap. Without changing the baseline, the platform position can be adjusted, making it convenient for operators to place paper. The lifting and lowering of the paper stacking platform can adjust the height of the top surface of the paper stack, facilitating stacking. Therefore, this utility model has substantial features and progress compared to the prior art. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0032] In the description of the present application, terms such as "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0033] See the attached Figure 1-2 , in the embodiment of this implementation manner, the adjustable artificial palletizing paper loading device includes a palletizing paper loading table 1 and a platform 2. The palletizing paper loading table 1 is arranged to be lifted and lowered. The palletizing paper loading table 1 has a supporting area 3. The platform 2 has a standing surface. The platform 2 is installed on a mounting frame 6. Multiple steps 7 are successively arranged on the mounting frame 6. The height of the steps 7 gradually decreases from front to back. A guardrail 8 is arranged circumferentially around the platform 2.

[0034] Among them, the platform 2 is arranged to move back and forth. A notch is provided at the rear side of the palletizing paper loading table 1 for the platform 2 to enter and exit. The notch corresponds to a non-supporting area 3. The notch is located in the middle of the palletizing paper loading table 1. The supporting area 3 is in a "U" shape. The supporting area 3 and the non-supporting area 3 together form a paper supporting surface. The platform 2 moves based on the front edge of the paper supporting surface to adjust the overlapping area in the up and down directions between the standing surface and the paper supporting surface.

[0035] In this implementation manner, at the start of paper feeding, the palletizing paper loading table 1 is at the high point. The operator climbs onto the platform 2 through multiple steps 7 to feed the paper. As the paper stack is stacked higher, the palletizing paper loading table 1 gradually descends so that the height of the upper surface of the paper stack remains unchanged. When the paper size becomes larger, the platform 2 moves backward to exit the notch. When the paper size becomes smaller, the platform 2 moves forward to enter the notch.

[0036] See the attached Figure 1-2 , the palletizing paper loading table 1 is arranged to be lifted and lowered on a mounting table 9. Casters 10 are provided on the front side of the mounting frame 6. The casters 10 are in rolling contact with the mounting table 9. A rack 11 is provided on the lower side of the mounting frame 6. The rack 11 meshes with a gear. The gear is传动连接 to a power source. A slider 13 is provided on the rear side of the mounting frame 6. The slider 13 is arranged to slide on a slide rail 14.

[0037] In this implementation manner, the power source drives the mounting frame 6 to move back and forth through the gear and the rack 11. The front side of the mounting frame 6 is supported by the mounting table 9 through the casters 10. The rear side of the mounting frame 6 is supported by the slide rail 14 through the slider 13. Among them, the slide rail 14 guides the back and forth movement of the mounting frame 6 through the slider 13. It should be noted that there is an unclear expression "传动连接" in the original text. It might be a misspelling or an incomplete term. Here it is left in the translation as it is for the sake of maintaining the original content. You may need to check and correct it according to the actual situation.

[0038] See appendix Figure 3 A connecting rod assembly 15 is connected between the mounting platform 9 and the paper stacking platform 1. The connecting rod assembly 15 is symmetrically arranged on the left and right sides of the mounting platform 9. The connecting rod assembly 15 includes a first connecting rod 16 and a second connecting rod 17. The middle part of the first connecting rod 16 is hinged to the middle part of the second connecting rod 17. The front end of the first connecting rod 16 is hinged to the paper stacking platform 1. The rear end of the first connecting rod 16 is in rolling contact with the mounting platform 9. The front end of the second connecting rod 17 is hinged to the mounting platform 9. The rear end of the second connecting rod 17 is in rolling contact with the paper stacking platform 1. A cylinder is hinged to the front part of the second connecting rod 17. The cylinder is connected to a drive block. The drive block is hinged to the front part of the first connecting rod 16.

[0039] In this embodiment, the cylinder uses a drive block to open or close the first connecting rod 16 and the second connecting rod 17 with the midpoint intersection as the reference. The rolling contact adapts to the opening or closing of the first connecting rod 16 and the second connecting rod 17 as the endpoints approach each other. The front ends of the first connecting rod 16 and the second connecting rod 17 are both hinged, which keeps the front side of the paper stack 1 stable and ensures that the baseline remains unchanged. The connecting rod assembly 15 is symmetrically arranged on the left and right sides of the mounting platform 9 to avoid interference with the moving platform 2.

[0040] In other alternative embodiments, the cylinder can be mounted on the mounting platform 9, and the cylinder can pull the first connecting rod 16 or the second connecting rod 17 to raise or lower the paper stacking platform 1, thereby adapting the force on the other connecting rod.

[0041] See appendix Figure 3 The non-supported area 3 is equipped with a support 18 for adjustable movement. The paper stacking platform 1 is provided with a support plate 19 for supporting the support 18. The support plate 19 is located on the left and right sides of the non-supported area 3. The support plate 19 is provided with adjustment holes arranged along the front-back direction for the installation of the limiting plate 20. The limiting plate 20 is provided with mounting holes. The distance between the support plates 19 is greater than the width of the platform 2.

[0042] In this embodiment, the support 18 is freely adjustable within the range defined by the limiting plate 20, making it easy to put in and take out. Adjusting the position of the limiting plate 20 allows the support 18 to avoid the platform 2.

[0043] In other embodiments, the support 18 can also be slidably set.

[0044] The above description represents the preferred embodiment of this utility model. It should be noted that the protection scope of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these modifications and substitutions are also considered to be within the protection scope of this utility model.
