DETAILED DESCRIPTION

[0026] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0030] The present application is further described below with reference to the accompanying drawings:

[0031] like Figures 1 to 9 As shown, the present application provides a transfer material receiving and loading system, including a material receiving device 1, a transfer vehicle 2 and a loading device 4. The transfer vehicle 2 is suitable for stacking materials 3. The material receiving device 1 is provided with a docking mechanism 11 and a lifting mechanism 12. The lifting mechanism 12 can select and load the materials 3 stacked on the transfer vehicle 2 in batches. The docking mechanism 11 is suitable for locking with the transfer vehicle 2. The docking mechanism 11 is suitable for making the transfer vehicle 2 close to the lifting mechanism 12, and making the materials 3 stacked on the transfer vehicle 2 always cooperate with the lifting mechanism 12 to ensure the normal loading operation. The loading device 4 can move the selected materials 3 to the equipment for processing and production.

[0032] By stacking on the transfer vehicle 2, a large number of materials 3 can be transported and transferred. The transfer vehicle 2, the docking mechanism 11 and the lifting mechanism 12 cooperate to select the material 3. There is no need to set the unloading process of the material 3, which reduces manual handling and manual assisted loading operations, and can also effectively reduce the difficulty of the loading device 4 to pick up the material 3, thereby improving the efficiency of the process from transfer to the middle of loading, and facilitating the loading device 4 to quickly transfer the material 3 to the equipment.

[0033] The lifting mechanism 12 includes a guide plate 121 and a lifter 122. A plurality of retractable ejectors 123 are arranged on the guide plate 121 along a first direction. The lifter 122 is liftably arranged on the side of the guide plate 121. The first direction corresponds to the lifting direction of the lifter 122. The lifter 122 is suitable for lifting and lifting part of the material 3 on the transfer vehicle 2 along the guide plate 121. The ejector 123 is suitable for extending out of the guide plate 121 after the lifter 122 is lifted, and limiting the movement of the remaining material 3 on the transfer vehicle 2. The loading device 4 is suitable for sequentially taking and conveying the material 3 lifted by the lifter 122 from above (which may be part or all of the lifted material 3), so that the material 3 stacked on the transfer vehicle 2 can be loaded in an orderly manner to ensure the smooth progress of production and processing.

[0034] It can be understood that, while ensuring the stacking stability of the stacked materials 3 on the transfer vehicle 2, by setting the contact form between the lifter 122 and the stacked materials 3 on the transfer vehicle 2, as well as the shape, length and other structural parameters of the contact part, diversified selection and batch loading of the stacked materials 3 on the transfer vehicle 2 can be achieved.

[0035] In some embodiments, the first direction is preferably set to a vertical direction, which can adapt to the material 3 lifting process while reducing the space occupied on the guide plate 121, making the overall structural layout more compact, thereby optimizing the space occupancy of the entire system.

[0036] like Figure 2 In the illustrated embodiment, when the material 3 is a strip-shaped material 3 of a relatively long length, the number of guide plates 121 and lifters 122 may be configured to be multiple, or a guide plate 121 with a larger surface area may be provided, and multiple channels for the lifters 122 to pass through may be opened on the guide plate 121, so that multiple lifters 122 can pass through the guide plate 121 and contact the material 3, and the guide plate 121 and lifter 122 are suitable for cooperating and contacting with the material 3 along the length direction of the stacked material 3 on the transfer vehicle 2, thereby improving the stability of the material 3 during the selection and lifting process, and ensuring that the material 3 can be picked up by the loading device 4 in the correct state.

[0037] In some embodiments, when the material 3 on the transfer vehicle 2 is a structure such as a square tube or a block, the operator can stack the material 3 in an array when loading. A lifting plate structure can be set on the lifter 122. After the transfer vehicle 2 is docked with the docking mechanism 11, the lifter 122 is suitable for lifting one or more columns of materials 3 on the transfer vehicle 2 along the guide plate 121 through the lifting plate. The loading device 4 is suitable for taking and conveying at least part of the material 3 in the one or more columns of materials 3 lifted by the lifter 122. In the present application, the loading device 4 usually takes part of the material 3 at the top of one or more columns of materials 3 in turn.

[0038] In some embodiments, when the material 3 on the transfer vehicle 2 is a structure such as a round tube, the operator can place and stack the material 3 in the form of an array through auxiliary clamps, and a corresponding clamp structure can also be set on the lifter 122. After the transfer vehicle 2 is docked with the docking mechanism 11, the lifter 122 is suitable for lifting one or more columns of materials 3 on the transfer vehicle 2 along the guide plate 121 through the clamp mechanism, and the loading device 4 is suitable for taking and conveying at least part of the material 3 in the one or more columns of materials 3 lifted by the lifter 122. In the present application, the loading device 4 usually takes part of the material 3 at the top of one or more columns of materials 3 in turn.

[0039] like Figure 5In the illustrated embodiment, the maximum length of the lifter 122 extending out of the surface of the guide plate 121 is no greater than the length of the ejector 123 extending out of the guide plate 121 when limiting the remaining materials 3 on the transfer vehicle 2, thereby ensuring the limiting effect of the ejector 123 on the remaining materials 3 on the transfer vehicle 2 and reducing the probability of the stacking state of the remaining materials 3 on the transfer vehicle 2 being damaged before the next lifting and selection by the lifter 122.

[0040] In some embodiments, the length of the ejector 123 extending out of the guide plate 121 when limiting the remaining material 3 on the transfer vehicle 2 is generally designed to be close to an integer multiple of the width of a single material 3, so that after the lifter 122 lifts one or more columns of materials 3 on the transfer vehicle 2, the ejector 123 can cross the vacant gap after the materials 3 are lifted and stably limit the remaining materials 3 on the transfer vehicle 2.

[0041] In some embodiments, the length of the ejector 123 extending out of the guide plate 121 can be designed to be elastic, and the maximum length of the ejector 123 extending out of the guide plate 121 is not less than the gap left after the material 3 is lifted. The ejector 123 can cross the gap left after the material 3 is lifted and hit the remaining material 3 on the transfer vehicle 2. At this time, the maximum length of the lifter 122 extending out of the surface of the guide plate 121 must still be no greater than the length of the ejector 123 extending out of the guide plate 121 when limiting the remaining material 3 on the transfer vehicle 2.

[0042] In some embodiments, the ejector 123 is a cylinder telescopic structure.

[0043] In some embodiments, the ejector 123 is a spring electromagnet telescopic structure.

[0044] In some embodiments, the lifter 122 is configured to be suitable for extension and retraction in a direction perpendicular to the surface of the guide plate 121. The lifter 122 is designed as a telescopic structure, which can enable the lifter 122 to retract to the inner side of the surface of the guide plate 121 during the process of descending after the lifting is completed, thereby reducing the probability of structural interference with the remaining materials 3 on the transfer vehicle 2, so as to reduce the impact on the stability of the stacking state of the remaining materials 3 on the transfer vehicle 2 before the next lifting and selection by the lifter 122.

[0045] In some embodiments, the lifter 122 is a cylinder telescopic structure.

[0046] In some embodiments, the lifter 122 is a spring electromagnet telescopic structure.

[0047] In some embodiments, when the lifter 122 lifts the material 3, multiple lifters 122 are suitable for cooperating to support and lift the material 3, which can improve the stability of the material 3 during the lifting process and reduce the probability of the material 3 falling during the lifting process.

[0048] like Figure 6In the illustrated embodiment, after the lifter 122 lifts the material 3, the ejector 123 is suitable for cooperating one by one to the nearest material 3 of the remaining material 3 on the transfer vehicle 2, or multiple ejectors 123 are suitable for cooperating with each other to the nearest material 3 of the remaining material 3 on the transfer vehicle 2. It can be understood that the ejector 123 can maintain the overall stacking stability of the material 3 by limiting and supporting a column of materials 3 of the remaining material 3 on the transfer vehicle 2 that is closest to the lifting mechanism 12, and cooperating with the transfer vehicle 2 to limit and support the remaining sides of the remaining material 3. Therefore, each material 3 in the column of materials 3 of the remaining material 3 on the transfer vehicle 2 that is closest to the lifting mechanism 12 needs to be restricted by at least one ejector 123. When the material 3 is a strip structure such as a square tube, a single material 3 can be restricted by multiple ejectors 123, so as to better maintain the stability of the stacking of the material 3.

[0049] In some embodiments, an absorber 124 is provided on the guide plate 121, and the absorber 124 is located above the ejector 123. The absorber 124 is suitable for enabling the lifter 122 to lift at least a portion of the material 3 close to the plane where the surface of the guide plate 121 is located. It can be understood that the absorber 124 can prevent the material 3 from falling, and help the feeding device 4 to position and stabilize the material 3, thereby reducing the probability of the feeding device 4 failing to pick up the material 3 and causing it to fall.

[0050] In some embodiments, the attractor 124 may be a magnet or an electromagnet, and preferably an electromagnet, which has a greater magnetic force and can fix the material 3 .

[0051] like Figures 2 to 7 In the illustrated embodiment, the suction end of the suction device 124 faces the transfer vehicle 2 and does not protrude from the surface of the guide plate 121. When the material 3 rises along the surface of the guide plate 121, structural interference between the suction device 124 and the material 3 can be reduced or even avoided, thereby improving the smoothness of material loading.

[0052] like Figure 2 , 3 In the embodiment shown in Figure 7, the lifting mechanism 12 includes a positioner 125, which is arranged on both sides of the guide plate 121. The positioner 125 is suitable for approaching or moving away from the guide plate 121 along the plane where the surface of the guide plate 121 is located. The positioner 125 can push the material 3 to move by contacting the two ends of the material 3, so that the material 3 remains in the same position during the loading process, thereby reducing the deviation of the material 3 during the loading process.

[0053] like Figure 3In the illustrated embodiment, further, the positioner 125 is arranged on both sides of the suction device 124 of the guide plate 121, and the positioner 125 is suitable for approaching or moving away from the suction device 124 along the plane where the surface of the guide plate 121 is located. It can be understood that the positioner 125 can help to position the material 3 currently to be taken by the loading device 4 and reduce its cost. At this time, the suction device 124 can also prevent the probability of the material 3 falling during the positioning process.

[0054] The material lifting mechanism 12 includes a positioning driver 126 and a transmission assembly 127. The positioning driver 126 is connected to the positioner 125 on one side of the guide plate 121, and the transmission assembly 127 is connected to the positioners 125 on both sides of the guide plate 121. The transmission assembly 127 is suitable for making the two positioners 125 move synchronously to clamp the material 3, so as to help keep the position of the material 3 consistent in the moving direction of the positioner 125 each time.

[0055] In some embodiments, the positioning driver 126 may be a cylinder, and the transmission assembly 127 may be a transmission guide such as a gear and a guide rail.

[0056] In some embodiments, the length of the positioner 125 and the guide in the first direction must be no less than the length of the number of materials 3 that can be loaded by the loading device 4 at a time, to ensure that the state of the material 3 to be loaded can be kept consistent.

[0057] In some embodiments, the activity state of the lifter 122 can be associated with the ejection state of the ejector 123 so that the ejector 123 can be ejected in time when the lifter 122 rises and passes by, thereby improving the operation stability.

[0058] In some embodiments, the guide plate 121 is provided with a plurality of travel switches along the first direction, and the travel switches are suitable for sensing the rising travel of the material 3 along the guide plate 121. The ejection state of the ejector 123 can be associated with the signal of the travel switch. When the lifter 122 is raised, when the travel switch below the lifter 122 loses the signal, it indicates that the material 3 corresponding to the ejector 123 has been raised and needs to be ejected by the ejector 123 to occupy the space. After the formation switch is added, it can be coordinated with the activity state of the linkage lifter 122 to improve the accuracy of the operation of the ejector 123.

[0059] In some embodiments, at least one travel switch is disposed in the horizontal plane where each ejector 123 is located, thereby improving the accuracy of identification and control.

[0060] In some embodiments, at least one travel switch is flush with the uppermost suction device 124. In addition to controlling the lifting height of the material 3 by setting a maximum lifting stroke for itself, the lifter 122 can also further cooperate to limit the lifting height of the material 3 through the travel switch, so that the material 3 can be lifted more accurately.

[0061] like Figures 3 to 6 In the illustrated embodiment, a docking hook 111 and a docking port 21 are provided on the transfer vehicle 2 and the docking mechanism 11 respectively. The docking hook 111 is adapted to extend into the docking port 21 and engage with the docking port 21 after rotation.

[0062] The docking mechanism 11 includes a docking driver 112 , which is connected to the docking hook 111 . The docking driver 112 is suitable for driving the docking hook 111 and making the transfer vehicle 2 approach the material lifting mechanism 12 .

[0063] like Figure 7 In the illustrated embodiment, the docking drive 112 includes a motor, a rotating shaft and a guide rail. The motor can enable the docking hook 111 to cooperate with the rotating shaft or the guide rail to perform corresponding actions. The rotating shaft can control the docking hook 111 to rotate and lock or unlock with the docking port 21. The guide rail can enable the docking hook 111 to pull the transfer vehicle 2 close to the lifting mechanism 12.

[0064] like Figure 8 In the shown embodiment, the transfer vehicle 2 includes a mobile base 22, a first baffle 23 and a second baffle 24. A universal wheel can be set under the mobile base 22 and moved by means of the first baffle 23. The first baffle 23 is fixedly arranged on one side of the mobile base 22 along the length direction of the mobile base 22. A sliding guide rail 25 is arranged at one end of the mobile base 22 along the length direction of the mobile base 22. The second baffle 24 is suitable for being slidably arranged on the sliding guide rail 25. By adjusting the position of the second baffle 24 on the sliding guide rail 25, the limiting fixation of one end of the material 3 is realized, so that materials 3 of different lengths can be accommodated. Different quantities of materials 3 can also be stacked in the length direction according to the requirements of the lifting mechanism 12 and the feeding device 4, thereby improving applicability.

[0065] like Figure 8 In the illustrated embodiment, a plurality of positioning holes 251 are provided on the sliding guide rail 25. The positioning holes 251 are suitable for installing pins to limit the sliding of the second baffle 24. The latch locking method can reduce the difficulty of operation and the complexity of the structure to simplify the cost. It can be understood that the positioning holes 251 opened on the movable base 22 can also play a corresponding role.

[0066] like Figure 8 In the illustrated embodiment, the top end of the second baffle 24 is set to be lower than the lowest position of the suction device 124 and the positioner 125, which can reduce the probability of structural interference between the operation of the second baffle 24 and the lifting mechanism 12, and especially can reduce the probability of structural interference between the operation of the second baffle 24 and the positioner 125.

[0067] like Fig. 9In the illustrated embodiment, the feeding device 4 includes a manipulator 41, a clamping mechanism 42 and a positioning mechanism 43. The clamping mechanism 42 and the positioning mechanism 43 are arranged on the manipulator 41. The manipulator 41 can flexibly control the changing direction and position of the clamping mechanism 42 and the positioning mechanism 43, so that the clamping mechanism 42 can cooperate with the clamping lifting mechanism 12 to lift the material 3.

[0068] like Fig. 9 In the illustrated embodiment, the clamping mechanism 42 includes a plurality of clamping jaws 421 , which are arranged at intervals along the first direction. The plurality of clamping jaws 421 can clamp different quantities of materials 3 and can also stably clamp longer materials 3 .

[0069] like Fig. 9 In the illustrated embodiment, the positioning mechanism 43 includes a positioning plate 431, which is disposed on both sides of the clamping mechanism 42 in the first direction. At least one side of the positioning plate 431 is suitable for approaching or moving away from the clamping mechanism 42 along the first direction. The positioning mechanism 43 can perform final positioning on the material 3 clamped by the clamp 421, thereby further improving the accuracy of loading the material 3.

[0070] In some embodiments, the operating principle of the positioning plate 431 can be the same as the operating principle of the positioner 125 .

[0071] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
