[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0025] The following refers to Figures 1-3 to understand the embodiments of the first aspect of the present invention.

[0026] First embodiment:

[0027] This embodiment discloses a stepped feeding device. Refer to Figure 1 for understanding. It includes an inclined bin 100, and the inclined bin 100 includes an inclined bottom plate 200 and a stepped lifting surface 300 that are connected to form the inclined bin 100. The inclined bottom plate 200 is inclined relative to the horizontal plane, and the lower part of the inclined surface is connected to the stepped lifting surface 300. The stepped lifting surface 300 is provided with a lifting device, and the lifting device is provided with a lifting surface 330, and the lifting surface 330 moves along the stepped lifting surface 300. It can be understood that due to the geometric characteristics of the cylindrical material 500, the cylindrical material 500 can automatically roll onto the stepped lifting surface 300 on the inclined bottom plate 200. This automatic rolling utilizes the shape and gravity of the material and does not require other driving forces, thus simplifying the process of material transportation. When the cylindrical material 500 rolls onto the stepped lifting surface 300, the lifting surface 330 will lift the material to a higher position as needed for further processing or transportation.

[0028] An arrangement bin 210 is further provided on the inclined bottom plate 200. The arrangement bin 210 includes a first bin body 220 and a pusher 230. The first bin body 220 is arranged in the arrangement bin 210. The direction of the first bin body 220 facing the stepped lifting surface 300 is the first direction, and the direction of the first bin body 220 facing the inclined bottom plate 200 is the second direction. As described above, the direction of the first bin body 220 facing the stepped lifting surface 300 is defined as the first direction, and the first direction is for material output, that is, the material leaves the bin through this direction and enters the stepped lifting surface 300. The direction facing the inclined bottom plate 200 is defined as the second direction, which is for material input, that is, the direction in which the cylindrical material 500 initially enters the bin.

[0029] Specifically, after the cylindrical material 500 is placed in the first bin body 220, the cylindrical material 500 will move in the bin along a preset path. The pusher 230 can push the material so that the material can be sent to the next processing stage in the correct order and direction from the bin. In this embodiment, the pusher 230 may adopt a robotic arm, a pneumatic push rod or other suitable mechanical devices to push the material along the first direction towards the stepped lifting surface 300 as needed. When the cylindrical material 500 reaches the stepped lifting surface 300, the lifting surface 330 moves along the stepped lifting surface 300 and can lift the material to a higher level according to the requirements of the material processing process.

[0030] Further refer to Figure 2It is understood that in the bottom area of the first bin body 220, a first opening 221 is provided on one side close to the stepped lifting surface 300, and an arc-shaped track 222 is provided at the first opening 221; a second opening 223 is formed in the top area of the first bin body 220, and the second opening 223 extends along the second direction to the bottom of the first bin body 220 and communicates with the first opening 221. Combining the foregoing structure, it can be seen that the cylindrical material 500 first enters through the second opening 223 located at the top of the first bin body 220, enters the bin body through the second opening 223, and falls to the bottom of the first bin body 220 under the action of gravity. After the cylindrical material 500 enters the bin body, the cylindrical material 500 at the bottom of the first bin body 220 leaves along the first opening 221.

[0031] When the material leaves the first opening 221, it continues to roll along the inclined bottom plate 200 until it rolls to the stepped lifting surface 300. After receiving the material, the lifting surface 330 moves it upward along the stepped lifting surface 300 to a set higher position for subsequent processing or distribution.

[0032] In this example, the arc-shaped track 222 has a guiding function and is used to change the moving direction of the cylindrical material 500 after the material leaves the first opening 221. The arc-shaped track 222 is connected to the first opening 221 to form a continuous path, which can change the direction of the material after it leaves the first opening 221, making it inclined relative to the first direction, so that it can smoothly roll to the stepped lifting surface 300 under the action of gravity.

[0033] In some examples, the radius of curvature and the track angle of the arc-shaped track 222 are calculated and determined to ensure that the cylindrical material 500 can maintain a stable rolling state when passing through the arc-shaped track 222 without jamming or deviating from the track. Through the guidance of the arc-shaped track 222, the material can naturally roll from the first opening 221 into the arc-shaped track 222, roll along the track path to the inclined bottom plate 200, and then continue to roll to the stepped lifting surface 300.

[0034] In this example, the pusher 230 includes a telescopic rod 231 and a top rod 234 connected as an integrated structure. At least a part of the telescopic rod 231 is arranged in the arrangement bin 210, and the telescopic rod 231 expands and contracts along the first direction; the top rod 234 has a first end 235 and a second end 236. The first end 235 is connected to the telescopic rod 231, and the second end 236 faces the first bin body 220; wherein, the axial direction of the top rod 234 is the first direction.

[0035] In this embodiment, the process of the telescopic rod 231 driving the ejector rod 234 to push the cylindrical material 500 in the first bin 220 is as follows:

[0036] The telescopic rod 231 reciprocates and expands and contracts along the first direction. The telescopic movement of the telescopic rod 231 is realized by its built-in driving mechanism, and the driving mechanism can be an electric, pneumatic or hydraulic device. The telescopic speed and stroke of the telescopic rod 231 are set according to the requirements of material transportation to ensure that the materials can be transported in sequence and stably.

[0037] When the telescopic rod 231 extends along the first direction, its first end 235 is connected to the ejector rod 234, driving the ejector rod 234 to move forward. The second end 236 of the ejector rod 234 faces the cylindrical material 500 in the first bin 220. When the ejector rod 234 moves forward, its end contacts the material and applies a thrust. At this time, the cylindrical material 500 starts to move along the first direction under the push of the ejector rod 234.

[0038] Under the push of the ejector rod 234, the cylindrical material 500 gradually leaves the first bin 220 and enters the arc track 222 through the first opening 221. Due to the arc track 222, after the material enters the arc track 222, its moving direction changes. The cylindrical materials 500 leaving the arc track 222 are not perpendicular to the first direction and can smoothly roll to the stepped lifting surface 300.

[0039] When the ejector rod 234 completes one pushing action, the telescopic rod 231 will retract to the initial position to prepare for the next pushing action. At this time, the overlapping cylindrical materials 500 in the first bin 220 will gradually move to the front of the ejector rod 234 under the action of gravity and be ready to receive the next push.

[0040] Based on the foregoing content, it can be seen that this embodiment can prevent the cylindrical material 500 from being perpendicular to the stepped lifting surface 300 and being unable to effectively roll to the stepped lifting surface 300. The foregoing example is only a possible implementation manner and does not limit the present invention. One can continue to refer to the subsequent embodiments for understanding.

[0041] Second Embodiment

[0042] Based on the foregoing embodiment, continue to refer to Figures 1-2 wherein a plurality of first bins 220 are arranged in an array in the arrangement bin 210. In this example, the arrangement bin 210 is a rectangular bin, and the first bins 220 are arranged in an array in the arrangement bin 210. Specifically, the first bin 220 is a cuboid cavity, the height direction of the cuboid cavity is the second direction, the length direction is the first direction, and the height of the first bin 220 is greater than the width.

[0043] It is understandable that the height of the first bin body 220 being greater than the width is aimed at optimizing the storage and pushing efficiency of the cylindrical materials 500. In this example, each of the first bin bodies 220 can accommodate multiple cylindrical materials 500 to form a vertical stack. This stacking structure utilizes the height of the bin body, enabling the materials to naturally accumulate under the action of gravity, thereby maximizing the utilization of the space of the bin body.

[0044] In the case of the material stacking arrangement, when the ejector rod 234 moves forward under the drive of the telescopic rod 231, the cylindrical material 500 at the bottom of the first bin body 220 is first pushed out. As the bottom material is pushed out, the cylindrical materials 500 above gradually fall under the action of gravity and successively fill the vacancies at the bottom. The ejector rod 234 can continuously push the cylindrical materials 500 out of the first bin body 220 one by one to ensure the orderly conveyance of the materials.

[0045] During the specific operation process, when the ejector rod 234 pushes the lowermost cylindrical material 500 out of the first bin body 220, the other materials in the bin body successively fall to prepare for the next push.

[0046] In some preferred examples, the bending direction of the arc-shaped track 222 forms an angle of no more than 30° with the first direction. In this embodiment, the angle being no more than 30° is to prevent the cylindrical materials 500 pushed out between two adjacent first bin bodies 220 from interfering with each other.

[0047] In some specific examples, the bottom surface of the first bin body 220 is the plate surface of the inclined bottom plate 200, and the arc-shaped track 222 is in the same inclined direction as the ejector rod 234 and the inclined bottom plate 200.

[0048] Third Embodiment

[0049] Based on the foregoing embodiments, in this example, further referring to Figure 3 the structure shown, the lifting device includes a lifting member 320. The top of the lifting member 320 is provided with the lifting surface 330, and the upper end of the stepped lifting surface 300 is provided with a conveying track 400. The lifting member 320 reciprocates along the stepped lifting surface 300; in the downward movement state of the lifting member 320, the lifting surface 330 is flush with the inclined bottom plate 200; in the upward movement state of the lifting member 320, the lifting surface 330 is flush with the conveying track 400.

[0050] In this example, the lifting member 320 includes a first lifting member 331 and a second lifting member 332. Among them, both the first lifting member 331 and the second lifting member 332 are connected to the driver. The first lifting member 331 and the second lifting member 332 are both connected to the driver. The first lifting member 331 is controlled by the driver, and its lifting height is flush with the lowest position of the second lifting member 332. The second lifting member 332 is controlled by another driver and can be lifted within a higher range and lifted to be flush with the conveying track 400.

[0051] Specifically, the first lifting member 331 includes a first lifting column and a first lifting plate. The first lifting column realizes the lifting movement through the driver. Its bottom is connected to the driver, and the top is connected to the first lifting plate. The first lifting plate is parallel to the inclined bottom plate 200 and moves up and down under the action of the first lifting column. In the initial state, the lifting plate is flush with the inclined bottom plate 200. When the driver is started, the first lifting column drives the first lifting plate to rise along the stepped lifting surface 300 until it is flush with the lowest position of the second lifting member 332.

[0052] The second lifting member 332 includes a second lifting column and the second lifting plate. Similar to the first lifting member 331, the lifting column of the second lifting member 332 also realizes the lifting movement through the driver. Its bottom is connected to an independent driver, and the top is connected to another second lifting plate. The lowest position of the second lifting member 332 is flush with the lifting height of the first lifting member 331, so as to realize the smooth transition of the material between the two lifting members 320.

[0053] When the material moves to the highest position on the first lifting plate of the first lifting member 331, the second lifting plate of the second lifting member 332 is flush with the lifting plate of the first lifting member 331, and the material can be smoothly transferred to the second lifting plate of the second lifting member 332. At this time, the driver of the second lifting member 332 is started, and the second lifting column drives the second lifting plate to continue to rise, further lifting the material to a position flush with the conveying track 400.

[0054] Fourth Embodiment

[0055] Based on the foregoing embodiments, in this example, the telescopic rod 231 includes a fixed section 232 and a telescopic section 233. You can continue to refer to Figure 1 for understanding (the structure of the telescopic rod 231 is fully shown in the figure). The fixed section 232 is a hollow rod body, and the telescopic section 233 is arranged to reciprocally contract within the fixed section 232. In the figure, the fixed end is arranged in the arrangement bin 210, and a part of the telescopic end is exposed outside the arrangement bin 210.

[0056] Among them, a first plate body is provided at the exposed end of the telescopic section 233. The first plate body is vertically arranged relative to the first direction. A ejector rod 234 is provided on the side of the first plate body facing the first bin 220. The telescopic rod 231 expands and contracts along the first direction under the action of a driver. The telescopic section 233 controls its telescopic movement through a built-in driver (such as an electric, pneumatic or hydraulic device). The expansion and contraction speed and stroke of the telescopic rod 231 are set according to the requirements of material transportation. During the telescopic process, the first plate is fixed at the exposed end of the telescopic section 233 and moves with the movement of the telescopic section 233. When the telescopic section 233 extends, the first plate moves in the first direction, and one side of it is connected to the ejector rod 234. The ejector rod 234 moves in the first direction under the drive of the first plate. The second end 236 of the ejector rod 234 contacts the cylindrical material 500 and applies a thrust force to make the cylindrical material 500 move in the first direction.

[0057] The Fifth Embodiment

[0058] Based on any of the foregoing embodiments, wherein the length of the ejector rod 234 is at least half of the length of the first bin 220 in the first direction. Its function is to prevent the cylindrical material from getting stuck in the first bin 220.

[0059] Based on any of the foregoing embodiments, wherein the distance between the arrangement bin 210 and the stepped lifting surface 300 in the first direction does not exceed the length of the first bin 220 in the first direction. Its function is to prevent the cylindrical material 500 from becoming parallel to the first direction again, resulting in its inability to roll onto the stepped lifting surface 300.
