[0025] 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 do not necessarily have to be used to describe a specific order or sequence.

[0026] The terms "comprising" and "having" in the description and claims of this application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0027] The following further describes this application in conjunction with the accompanying drawings:

[0028] As Figures 1 to 6 shown, this application provides a material receiving device, including a docking mechanism 11 and a material lifting mechanism 12. The material lifting mechanism 12 can select and batch-feed the materials 3 stacked on the transfer vehicle 2. The docking mechanism 11 is adapted to cooperate and lock with the transfer vehicle 2. The docking mechanism 11 is adapted to bring the transfer vehicle 2 close to the material lifting mechanism 12 and enable the materials 3 stacked on the transfer vehicle 2 to always cooperate with the material lifting mechanism 12, ensuring the normal progress of the feeding operation.

[0029] By stacking materials 3 on the transfer vehicle 2, the handling and transfer of a relatively large number of materials 3 can be achieved. When the transfer vehicle 2 cooperates with the docking mechanism 11 and the material lifting mechanism 12 to select materials 3, there is no need to set a discharging process for the materials 3, reducing operations such as manual handling and manual-assisted feeding, thereby improving the efficiency of the process from transfer to feeding intermediate.

[0030] The material lifting mechanism 12 includes a guide plate 121 and a material lifter 122. A plurality of telescopic ejectors 123 are arranged along the first direction on the guide plate 121. The material lifter 122 is arranged on the periphery of the guide plate 121 in a liftable manner. The material lifter 122 is adapted to rise and lift a part of the materials 3 on the transfer vehicle 2 along the guide plate 121. The ejectors 123 are adapted to extend out of the guide plate 121 after the material lifter 122 rises and restrict the movement of the remaining materials 3 on the transfer vehicle 2. The feeding equipment is adapted to sequentially pick up and convey the materials 3 lifted by the material lifter 122 from above (which can be part or all of the lifted materials 3), so that the materials 3 stacked on the transfer vehicle 2 can be fed in an orderly manner, ensuring the smooth progress of production and processing.

[0031] It can be understood that, on the premise of ensuring the stacking stability of the materials 3 stacked on the transfer vehicle 2, by setting the contact form between the material lifter 122 and the materials 3 stacked on the transfer vehicle 2, as well as structural parameters such as the shape and length of the contact part, diverse selection and batch-feeding of the materials 3 stacked on the transfer vehicle 2 can be achieved.

[0032] In some embodiments, the first direction is preferably set as the vertical direction, which can cooperate with and adapt to the process of lifting the material 3 while reducing the occupation of the space on the guiding plate 121, making the overall structural layout more compact, thereby optimizing the space occupation of the entire system.

[0033] As Figure 2 In the embodiment shown, when the material 3 is a strip-shaped material 3 with a relatively long length, the number of guiding plates 121 and lifters 122 can be configured as multiple, or a guiding plate 121 with a larger surface area can be set, and multiple channels for the lifters 122 to pass through are opened on the guiding plate 121, so that multiple lifters 122 can pass through the guiding plate 121 to contact the material 3. The guiding plate 121 and the lifters 122 are adapted to cooperate and contact with the material 3 along the length direction of the stacked material 3 on the transfer vehicle 2, thereby being able to improve the stability of the material 3 during the selection and lifting processes and ensuring that the material 3 can be taken by the feeding device in the correct state.

[0034] In some embodiments, when the material 3 on the transfer vehicle 2 is in the form of a square tube, a block, etc., the operator can stack the materials 3 in an array form during loading. A lifting plate structure can be provided on the lifter 122. After the transfer vehicle 2 is docked with the docking mechanism 11, the lifter 122 is adapted to lift one or more columns of the materials 3 on the transfer vehicle 2 along the guiding plate 121 through the lifting plate. The feeding device is adapted to take and convey at least part of the materials 3 in one or more columns of the materials 3 lifted by the lifter 122. In this application, the feeding device usually takes the materials 3 at the top of one or more columns of the materials 3 in sequence.

[0035] In some embodiments, when the material 3 on the transfer vehicle 2 is in the form of a round tube, etc., the operator can stack the materials 3 in an array form through an auxiliary fixture. A fixture structure can also be correspondingly provided on the lifter 122. After the transfer vehicle 2 is docked with the docking mechanism 11, the lifter 122 is adapted to lift one or more columns of the materials 3 on the transfer vehicle 2 along the guiding plate 121 through the fixture mechanism. The feeding device is adapted to take and convey at least part of the materials 3 in one or more columns of the materials 3 lifted by the lifter 122. In this application, the feeding device usually takes the materials 3 at the top of one or more columns of the materials 3 in sequence.

[0036] As Figure 5 In the embodiment shown, the maximum length of the lifter 122 extending out of the surface of the guiding plate 121 is not greater than the length of the ejector 123 extending out of the guiding plate 121 when restricting the remaining material 3 on the transfer vehicle 2, which can ensure the restricting effect of the ejector 123 on the remaining material 3 on the transfer vehicle 2 and reduce the probability of the stacking state of the remaining material 3 on the transfer vehicle 2 being damaged before the next lifting and selection by the lifter 122.

[0037] In some embodiments, when the ejector 123 restricts the remaining material 3 on the transporter 2, the length that the ejector 123 extends out of the guide plate 121 is generally designed to be an integer multiple close to the width of a single material 3, so that after the lifter 122 lifts one or more columns of materials 3 on the transporter 2, the ejector 123 can cross the gap vacated after the material 3 is lifted and stably restrict the remaining material 3 on the transporter 2.

[0038] In some embodiments, the length that the ejector 123 extends out of the guide plate 121 can be elastically designed. The maximum length that the ejector 123 extends out of the guide plate 121 is not less than the gap vacated after the material 3 is lifted. The ejector 123 can cross the gap vacated after the material 3 is lifted and abut against the remaining material 3 on the transporter 2. At this time, the maximum length that the lifter 122 extends out of the surface of the guide plate 121 still needs to be not greater than the length that the ejector 123 extends out of the guide plate 121 when restricting the remaining material 3 on the transporter 2.

[0039] In some embodiments, the ejector 123 is a cylinder telescopic structure.

[0040] In some embodiments, the ejector 123 is a spring electromagnet telescopic structure.

[0041] In some embodiments, the lifter 122 is arranged to be suitable for telescoping in a direction perpendicular to the surface of the guide plate 121. Designing the lifter 122 as a telescopic structure can enable the lifter 122 to retract to the inside 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 material 3 on the transporter 2, so as to reduce the influence on the stability of the stacking state of the remaining material 3 on the transporter 2 before the next lifter 122 lifts and selects.

[0042] In some embodiments, the lifter 122 is a cylinder telescopic structure.

[0043] In some embodiments, the lifter 122 is a spring electromagnet telescopic structure.

[0044] 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.

[0045] Such as Figure 6In the illustrated embodiment, after the lifter 122 lifts the material 3, the ejector 123 is adapted to cooperate one by one and abut against the closest material 3 of the remaining material 3 on the transfer vehicle 2, or a plurality of ejectors 123 are adapted to cooperate with each other and abut against the closest 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 restricting and supporting the column of material 3 closest to the lifting mechanism 12 on the remaining material 3 on the transfer vehicle 2 and cooperating with the transfer vehicle 2 to restrict and support the other sides of the remaining material 3. Therefore, each material 3 in the column of material 3 closest to the lifting mechanism 12 on the remaining material 3 on the transfer vehicle 2 needs to be restricted by at least one ejector 123. When the material 3 is a strip structure such as a square pipe, a single material 3 can be restricted by a plurality of ejectors 123, so as to better maintain the stacking stability of the material 3.

[0046] In some embodiments, an attractor 124 is provided on the guide plate 121. The attractor 124 is located above the ejector 123. The attractor 124 is adapted to make at least a part of the material 3 lifted by the lifter 122 closely adhere to the plane where the surface of the guide plate 121 is located. It can be understood that the attractor 124 can prevent the material 3 from falling, and help the feeding device locate and stabilize the material 3, reducing the probability of the feeding device failing to pick up the material 3 and causing it to fall.

[0047] In some embodiments, the attractor 124 can be a magnet or an electromagnet. Preferably, an electromagnet is used, and the electromagnet can have a greater magnetic force, so as to play a role in fixing the material 3.

[0048] As Figures 2 to 6 In the illustrated embodiment, the attracting end of the attractor 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 attractor 124 and the material 3 can be reduced or even avoided, thereby improving the feeding smoothness.

[0049] As Figure 2 In the illustrated embodiment, the lifting mechanism 12 includes a positioner 125. The positioner 125 is arranged on both sides of the guide plate 121. The positioner 125 is adapted to approach or move 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 abutting against both ends of the material 3, so that the material 3 remains in the same position during the feeding process, reducing the offset of the material 3 during the feeding process.

[0050] As Figure 3In the illustrated embodiment, further, the positioners 125 are disposed on both sides of the suction device 124 of the guiding plate 121. The positioners 125 are adapted to approach or move away from the suction device 124 along the plane where the surface of the guiding plate 121 is located. It can be understood that the positioners 125 can help position the material 3 to be picked up by the feeding device currently and reduce its deviation. At this time, the suction device 124 can also reduce the probability of the material 3 falling during the positioning process.

[0051] The 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 guiding plate 121, and the transmission assembly 127 is connected to the positioners 125 on both sides of the guiding plate 121. The transmission assembly 127 is adapted to make the two positioners 125 act synchronously to clamp the material 3, and help the position of the material 3 in the moving direction of the positioner 125 to be consistent each time.

[0052] In some embodiments, the positioning driver 126 can be a cylinder, and the transmission assembly 127 can be transmission guiding members such as gears and guide rails.

[0053] In some embodiments, the length of the positioner 125 and the guide in the first direction needs to be not less than the length of the number of materials 3 that can be fed by the feeding device at one time, so as to ensure that the states of the materials 3 to be fed are consistent.

[0054] In some embodiments, the active state of the lifter 122 can be associated with the ejecting state of the ejector 123, so that the ejector 123 can eject in time when the lifter 122 rises past, improving the operation stability.

[0055] In some embodiments, the guiding plate 121 is provided with a plurality of travel switches along the first direction. The travel switches are adapted to sense the upward travel of the material 3 along the guiding plate 121. The ejecting state of the ejector 123 can be associated with the signals of the travel switches. When the lifter 122 rises and the travel switch below the lifter 122 loses the signal, it indicates that the material 3 corresponding to the ejector 123 has risen and needs to be ejected by the ejector 123 to occupy the space. After adding the travel switches and coordinating with the active state of the lifter 122, the operation accuracy of the ejector 123 can be improved.

[0056] In some embodiments, at least one travel switch is provided in the horizontal plane where each ejector 123 is located, thereby improving the accuracy of identification and control.

[0057] 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 the maximum lifting stroke of itself, the lifter 122 can further cooperate with the travel switch to limit the lifting height of the material 3, making the lifting of the material 3 more accurate.

[0058] In Figures 3 to 6 the illustrated embodiment, a docking hook 111 and a docking port 21 are respectively provided on the transfer vehicle 2 and the docking mechanism 11. The docking hook 111 is adapted to extend into the docking port 21 and, after rotation, is snap-fitted with the docking port 21.

[0059] The docking mechanism 11 includes a docking driver 112. The docking driver 112 is connected to the docking hook 111 and is adapted to drive the docking hook 111 and move the transfer vehicle 2 closer to the lifting mechanism 12.

[0060] In Figure 1 the illustrated embodiment, the docking driver 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 rotation of the docking hook 111 and lock or unlock it with the docking port 21. The guide rail can enable the docking hook 111 to pull the transfer vehicle 2 closer to the lifting mechanism 12.
