[0002] Currently, shaft tube parts are usually stored on a stereoscopic shelf. Although it saves floor space and improves space utilization rate, it is not convenient to pick and place. To solve the problem of inconvenient picking and placing, some enterprises or factories store shaft tube parts on a flow-through shelf. The flow-through shelf is also called a sliding shelf. Its slideway uses roller aluminum alloy, sheet metal and other flow-through strips. Utilizing the self-weight of the parts, goods are stocked from one side of the slideway and picked from the other side, realizing first-in, first-out. It is convenient for storage, can replenish goods once and pick goods multiple times, and has the characteristics of high storage efficiency and being suitable for short-term storage and picking of a large number of goods. It is widely used in distribution centers, assembly workshops and warehouses with a high shipping frequency.

[0003] However, when the existing flow-through shelf stores shaft tube parts, the later placed parts will hit the previously stored parts when rolling from a high place to a low place on the flow-through strip. Moreover, the longer the rolling distance, the more intense the impact, which will not only damage the parts, but also generate a huge noise. Summary of the Invention

[0004] The embodiment of this application provides a storage device for shaft tube parts, which is used to solve the technical problems that when the existing flow-through shelf stores shaft tube parts, the later placed parts will hit the previously stored parts, causing damage to the parts and generating noise.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0044] It should also be noted that in the embodiments of the present application, the same reference numerals are used to represent the same components or the same parts. For the same parts in the embodiments of the present application, only one of the parts or components may be marked with a reference numeral in the drawings. It should be understood that the reference numerals are equally applicable to other identical parts or components.

[0045] As described in the background art, when storing shaft tube parts in the existing gravity flow rack, the parts placed later will hit the previously stored parts when rolling from a high place to a low place on the gravity flow bar. Moreover, the longer the rolling distance, the more violent the impact, which will not only damage the parts but also generate a huge noise.

[0046] To solve the above problems, the embodiments of the present application provide a storage device for shaft tube parts, such as Figures 1-2As shown in the figure, the storage device for shaft tube parts includes a bracket 100, a placement rack 200, and a deceleration mechanism 300. The placement rack 200 is inclined and arranged on the bracket 100, and the placement rack 200 is used for placing shaft tube parts. The deceleration mechanism 300 is arranged on the bracket 100 and above the placement rack 200. The deceleration mechanism 300 includes a movable member 310 and a telescopic driving member 320 arranged on the bracket 100 and connected to the movable member 310. The telescopic driving member 320 is used to drive the movable member 310 to reciprocate between approaching and departing from the placement rack 200, so that the movable member 310 can be switched between a pressing state close to the placement rack 200 and a disengaged state away from the placement rack 200. Among them, in the pressing state, the movable member 310 can press the shaft tube part 10 placed on the placement rack 200 against the placement rack 200. In the disengaged state, the movable member 310 is disengaged from contact with the shaft tube part 10 on the placement rack 200.

[0047] In the embodiment of the present application, the storage device for shaft tube parts is provided with a deceleration mechanism 300 above the placement rack 200. The telescopic driving member 320 in the deceleration mechanism 300 is used to drive the movable member 310 to reciprocate between approaching and departing from the placement rack 200, so that the movable member 310 can be switched between a pressing state and a disengaged state. By continuously pressing and releasing the shaft tube part 10 on the placement rack 200 by the movable member 310, the deceleration effect on the shaft tube part 10 during the rolling process from the high end to the low end on the placement rack 200 is achieved, reducing the impact force of the later placed parts on the previously stored parts, and reducing the damage to the parts and the generated noise.

[0048] It can be understood that in the pressing state, the shaft tube part 10 on the placement rack 200 is pressed against the placement rack 200 by the movable member 310, and the shaft tube part 10 cannot roll towards the low end under its own gravity. In the disengaged state, the shaft tube part 10 can roll towards the low end under its own gravity. The deceleration mechanism 300 divides the original long rolling stroke into multiple short rolling strokes, so that the speed of the shaft tube part 10 cannot increase during the rolling process from the high end to the low end on the placement rack 200, thereby reducing the impact force of the later placed parts on the previously stored parts, and reducing the damage to the parts and the generated noise. By controlling the telescopic frequency of the telescopic driving member 320, the switching frequency between the pressing state and the disengaged state of the movable member 310 can be changed, achieving the purpose of adjusting the deceleration degree.

[0049] It should be noted that the high end of the placement rack 200 refers to the end with a higher position of the placement rack 200 in the height direction of the bracket 100, and the high end corresponds to the feeding position on the placement rack 200 ( Figure 2 shown as G); the low end of the placement rack 200 refers to the end with a lower position of the placement rack 200 in the height direction of the bracket 100, and the low end corresponds to the picking position on the placement rack 200 (Figure 2 Shown as D. The shaft tube parts 10 are placed on the feeding position of the placement rack 200 and roll towards the picking position under their own gravity, and finally, as Figure 3 shown, fill the entire placement rack 200.

[0050] In one embodiment, as Figures 1-3 shown, the movable part 310 includes a movable rod, and the length direction of the movable rod is perpendicular to the length direction of the shaft tube parts on the placement rack 200.

[0051] The movable rod has a simple structure, is convenient for installation and arrangement, and has a low cost. By arranging the movable rod as above, it can act on the rolling direction of the shaft tube parts throughout its entire length.

[0052] Furthermore, at least one side of the movable rod facing the placement rack 200 is provided with a protective pad, and the protective pad can be made of soft and elastic materials such as rubber, silica gel or foam, so as to avoid the metal movable rod directly pressing against the shaft tube parts and causing damage to the shaft tube parts.

[0053] It can be imagined that in other embodiments, the movable part 310 can also adopt a plate structure or a frame structure, etc.

[0054] In a specific embodiment, as Figures 2-3 shown, the telescopic driving part 320 includes a linear cylinder. The cylinder body of the linear cylinder is hinged to the bracket 100, the piston rod of the linear cylinder is hinged to one end of the movable rod, and the other end of the movable rod is hinged to the bracket 100.

[0055] By setting as above, using the linear cylinder as the telescopic driving part 320 is convenient for installation, has a low cost, and has a rapid action.

[0056] It should be noted that when the distance from the high end to the low end of the placement rack 200 is relatively long, a plurality of deceleration mechanisms 300 in this embodiment can be arranged in the rolling direction of the shaft tube parts.

[0057] Of course, it can be imagined that in other embodiments, the telescopic driving part 320 in this embodiment can also adopt an electric cylinder or an electric push rod, etc.

[0058] In one embodiment, as Figure 1 shown, a centering mechanism 400 is provided at the low end of the placement rack 200 on the bracket 100, and the centering mechanism 400 is used to clamp and center the shaft tube parts located at the low end of the placement rack 200.

[0059] By setting the centering mechanism 400, it can ensure the accurate position of the shaft tube parts 10 at the picking position, and is convenient for the gripping device (not shown in the figure) to accurately grip the shaft tube parts 10 located at the picking position.

[0060] In a specific embodiment, as Figure 3 shown, the centering mechanism 400 includes two centering blocks 420 and two centering cylinders 410. The two centering cylinders 410 are respectively arranged at opposite ends of the support 100 in the axial direction of the tubular part 10 at the material taking position, and the piston rod movement directions of the two centering cylinders 410 are opposite. The two centering blocks 420 are respectively fixed on the piston rods of the two centering cylinders 410. The two centering cylinders 410 respectively drive the two centering blocks 420 to open and close relatively in the axial direction of the tubular part 10 at the material taking position, so as to clamp or release the tubular part 10 at the material taking position. Through the above arrangement, the centering mechanism 400 has a simple structure, is convenient to install, and saves costs.

[0061] It can be understood that in other embodiments, the centering cylinder 410 in the above implementation manner can also be replaced by an electric cylinder or a linear module.

[0062] In some embodiments, the slope angle of the plane where the placement rack 200 is located is designed to be 2° - 3°, preferably 2.5°. With this design, the placement rack 200 will neither be too steep to cause the tubular part to roll too fast, nor be too gentle to cause the tubular part to roll slowly.

[0063] In one embodiment, as Figures 1-2 shown, the placement rack 200 includes at least two spaced support rods 210. In the height direction of the support 100, the plane where the at least two support rods 210 are located is inclined from one end to the other end of the support rods 210, and a stop member 211 for preventing the tubular part from falling off is fixed at the low ends of the at least two support rods 210.

[0064] With the placement rack 200 arranged as above, it has a simple structure, low cost, light weight, and is convenient to arrange.

[0065] Of course, in other embodiments, the placement rack 200 can also adopt a whole inclined support plate.

[0066] In one embodiment, as Figures 1-4 shown, a separation mechanism 500 is further arranged on the support 100 near the low end of the placement rack 200. There is a separation position corresponding to the separation mechanism 500 on the placement rack 200 ( Figure 4 shown as F in the figure), and the separation mechanism 500 is used to release the tubular parts 10 placed between the separation position and the high end of the placement rack 200 to the low end of the placement rack 200 one by one.

[0067] By arranging the separation mechanism 500, the tubular parts 10 stored on the placement rack 200 can be released to the material taking position of the placement rack 200 one by one, which is convenient for subsequent material taking.

[0068] Specifically, asFigure 4 As shown, the separating mechanism 500 includes a Y-shaped fork 510 hinged in the middle to the bracket 100 and a separating cylinder 520 with its cylinder body hinged to the bracket 100 and its piston rod hinged to one end of the Y-shaped fork 510. By driving the Y-shaped fork 510 to swing reciprocally through the separating cylinder 520, the purpose of separating the tubular parts 10 one by one is achieved.

[0069] In one embodiment, as Figure 5 shown, the placing rack 200 is provided with multiple layers, and the multiple layers of placing racks 200 are spaced apart in the height direction of the bracket 100.

[0070] By providing multiple layers of placing racks 200 on the bracket 100, the storage capacity of the storage device for tubular parts is improved, and the space utilization rate is increased under the condition of the same floor area.

[0071] In a specific embodiment, as Figure 5 shown, the multiple layers of placing racks 200 include a top placing rack 2001 and multiple temporary placing racks 2002. The multiple temporary placing racks 2002 are arranged parallel and spaced apart in the height direction of the bracket 100. The top placing rack 2001 is located above all the temporary placing racks 2002, and the lower end of the top placing rack 2001 is directly above the upper end of the temporary placing racks 2002.

[0072] With the above arrangement, the multiple temporary placing racks 2002 are mainly used for storing the tubular parts, and the top placing rack 2001 is mainly used for the external access of the tubular parts.

[0073] To facilitate the transfer of parts between different placing racks 200, please continue to refer to Figure 5 , the storage device for tubular parts further includes two transfer devices 600. The two transfer devices 600 are respectively arranged at the opposite ends of the multiple layers of placing racks 200 (i.e., the left and right ends of the bracket 100 in the figure), and the transfer device 600 is used to transfer the tubular parts between different placing racks 200.

[0074] To facilitate the storage of tubular parts into the placing rack 200, a conveyor 700 is provided beside the transfer device 600 on the high-end side of the multiple temporary placing racks 2002. As Figure 7 shown, the conveyor 700 includes a frame body 710, a plurality of conveyor rollers 720 rotatably arranged in the length direction of the frame body 710, and a driving mechanism (not shown in the figure) for driving the conveyor rollers 720 to operate. A circle of V-shaped grooves is arranged along the circumferential direction of the conveyor rollers 720 to facilitate the stable conveyance of the cylindrical tubular parts.

[0075] In a more specific embodiment, as Figure 6As shown, the transfer device 600 includes a lifting device 610 and a flipping device 620. The lifting device 610 has a frame 611 and a lifting frame 612 disposed on the frame 611. The lifting frame 612 can move in the height direction of the frame 611. An elevating mechanism 613 is provided on the frame 611. The elevating mechanism 613 is connected to the lifting frame 612 and is used to drive the lifting frame 612 to move in the height direction of the frame 611. The flipping device 620 is disposed on the lifting frame 612. The flipping device 620 includes a support bracket 621 for supporting tubular parts and a flipping drive mechanism 622 disposed on the lifting frame 612 and connected to the support bracket 621. A support position 6201 is provided on the support bracket 621. The support bracket 621 is rotatably disposed on the lifting frame 612. The flipping drive mechanism 622 is used to drive the support bracket 621 to flip relative to the lifting frame 612, so that the support bracket 621 can be switched between a material storage state and a discharging state; wherein, in the material storage state, the height of the support bracket 621 gradually decreases from the end far away from the lifting frame 612 to the support position 6201; in the discharging state, the height of the support bracket 621 gradually decreases from the support position 6201 to the end far away from the lifting frame 612.

[0076] By driving the support bracket 621 to flip relative to the lifting frame 612 through the flipping drive mechanism 622 (such as a cylinder hinged between the support bracket 621 and the lifting frame 612), the support bracket 621 can be switched between the material storage state and the discharging state. In the material storage state, the height of the support bracket 621 gradually decreases from the end far away from the lifting frame 612 to the support position 6201. At this time, the tubular parts can roll from the end of the support bracket 621 far away from the lifting frame 612 to the support position 6201 and be stored on the support position 6201. After adjusting the support bracket 621 to a suitable height through the lifting device 610, the flipping drive mechanism 622 is used to drive the support bracket 621 to switch from the material storage state to the discharging state. At this time, the height of the support bracket 621 gradually decreases from the support position 6201 to the end far away from the lifting frame 612, and the tubular parts stored on the support bracket 621 can roll down from the support bracket 621 under their own gravity to complete the discharging. Through the transfer device 600, the transfer of tubular parts between the upper and lower storage layers can be realized instead of manual labor, and the transfer efficiency of tubular parts can be improved.

[0077] Furthermore, an alignment mechanism 400 is further provided on the lifting frame 612. The alignment mechanism 400 is used to align and clamp the tubular parts located on the support position 6201. The structure of the alignment mechanism 400 has been introduced in detail in the alignment mechanism 400 on the lower end of the placement frame 200 on the middle bracket 100 in the above embodiment Figure 3 and will not be elaborated here.

[0078] By providing the alignment device on the lifting frame 612, the position of the tubular parts on the support position 6201 can be ensured to be accurate.

[0079] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope recorded in this specification.

[0080] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
