Description

Technical Field

[0001] The utility model relates to the field of pull rod storage, in particular to a layered pull rod three-dimensional storage shelf. Background Art

[0002] A Chinese patent with the publication number CN213863494U discloses a shaft cargo transfer shelf, which includes a bracket. A plurality of strip plates are arranged in parallel and at intervals on the bracket, and a plurality of arc-shaped grooves for placing shaft parts are symmetrically arranged on the plurality of strip plates.

[0003] The arc-shaped grooves in the above structure can be used to place shaft parts. If the mass of the shaft parts is large, a manipulator is required to place the shaft parts into the arc-shaped grooves. If the number of long shaft parts to be placed is large, in order to increase the space utilization rate, multiple brackets equipped with strip plates can be vertically stacked. However, the multi-layer setting will cause interference between the manipulators during placement, resulting in great difficulty in placing the manipulators. Summary of the Utility Model

[0004] Aiming at the shortcomings of the prior art that if the number of long shaft parts to be placed is large, in order to increase the space utilization rate, multiple brackets equipped with strip plates can be vertically stacked. However, the multi-layer setting will cause interference between the manipulators during placement, resulting in great difficulty in placing the manipulators, the utility model provides a layered pull rod three-dimensional storage shelf.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A layered pull rod three-dimensional storage shelf includes a shelf body, the shelf body includes a frame body, conveyor chains arranged in parallel on both sides of the frame body, and a driving component for driving the two conveyor chains to rotate synchronously. A placement position for placing both ends of the product is formed between the conveyor chains, and a plurality of placement positions are arranged along the conveying direction. At least two shelf bodies are inserted into the shelf body in a stepped manner, and the end at the conveying inlet is a fixed placement station for workpieces and the fixed placement station is in an exposed state.

[0007] By adopting the above scheme, setting at least two shelf bodies can store more pull rods. Since the fixed placement station is in an exposed state, it is convenient for the manipulator to place the pull rods in the shelf bodies on different steps. When the pull rod is placed on the fixed placement station on the shelf body, the set driving component will drive the conveyor chain to rotate. At this time, the conveyor chain will drive the pull rod placed in the shelf body to move, so that a new placement position without a pull rod will move to the fixed placement station, and the manipulator can place other pull rods at this new fixed placement station, thereby reducing the interference of multiple shelf bodies on the placement of the manipulator during placement, and thus reducing the difficulty of placing the pull rod by the manipulator.

[0008] Preferably, a number of V-shaped blocks with openings facing upward are arranged at intervals along the conveying direction on the upper end surfaces of the two conveying chains. The V-shaped blocks on the two conveying chains are arranged in one-to-one correspondence, and the corresponding two V-shaped blocks form a placement position.

[0009] With the above solution, the V-shaped blocks provided on the conveying chain can be used to place one end of the pull rod, and by arranging the V-shaped blocks on the two conveying chains in one-to-one correspondence, a placement position for placing both ends of the pull rod can be formed, thereby storing the pull rod.

[0010] Preferably, auxiliary components for assisting the operator to quickly bundle all the workpieces placed on the shelf body are provided on the two conveying chains.

[0011] Preferably, the auxiliary components include a pull rope and a hook. The hook is fixed on the opposite side of the conveying chain, and the hook is arranged in one-to-one correspondence with the V-shaped block and is located below the V-shaped block. One end of the pull rope is fixed on the hook corresponding to the fixed placement station, and the other end of the pull rope is fixed on a fixed component located at the conveying inlet.

[0012] With the above solution, the hook provided below the V-shaped block can be used for the pull rope. Since the hook is arranged below the V-shaped block, the hook will move together with the V-shaped block, and the hook will pull the pull rope to move. At this time, the pull rope will gradually cover the upper part of the pull rod. When all the pull rods on the rack need to be removed, the fixation between the pull rope near the hook side and the hook can be released, and the pull rope can be pulled so that the pull rope passes through the lower part of all the pull rods. Then, the pull rope near the fixed component end is released, and the two ends of the pull rope are fixed on the traveling crane. At this time, all the pull rods on the shelf body can be unloaded from the shelf body at one time.

[0013] Preferably, the driving component includes a rotating shaft rotatably arranged at both ends of the rack, transmission gears coaxially fixed at both ends of the rotating shaft and respectively meshed with a conveying chain, and a driving member for driving one of the rotating shafts to rotate.

[0014] With the above solution, the driving member provided can drive the rotating shaft to rotate. When the rotating shaft rotates, the transmission gears arranged at both ends of the rotating shaft will also rotate together with the rotating shaft. Since the transmission gears are meshed with the conveying chain, the conveying chain will rotate following the transmission gears, so that the pull rod placed at the fixed placement station by the manipulator moves forward. At this time, other empty placement positions will rotate to the fixed placement station, which is convenient for the manipulator to place a new pull rod on the placement position newly moved to the fixed placement station.

[0015] Preferably, the driving member includes a motor fixed on the rack. A driving wheel is arranged on the output shaft of the motor, and a driven wheel that can rotate following the driving wheel and drive the rotating shaft to rotate is arranged at the position on the rotating shaft opposite to the driving wheel.

[0016] With the above solution, the motor can drive the driving wheel to drive the driven wheel on the rotating shaft to rotate, so that the rotating shaft drives the conveyor chain to rotate, and the pull rod placed at the fixed placement station by the manipulator is moved, facilitating the manipulator to place a new pull rod at the end of the conveyor chain inlet.

[0017] Since the present utility model adopts the above technical solution, it has remarkable technical effects: at least two shelf bodies are provided to accommodate more pull rods. Since the fixed placement station is in an exposed state, it is convenient for the manipulator to place the pull rods in the shelf bodies on different steps. When the pull rod is placed at the fixed placement station on the shelf body, the driving component drives the conveyor chain to rotate. At this time, the conveyor chain drives the pull rod placed in the shelf body to move, so that the new placement position without a pull rod moves to the fixed placement station, and the manipulator can place other pull rods at this new fixed placement station, thereby reducing the interference of multiple shelf bodies on the placement of the manipulator and reducing the difficulty of the manipulator placing the pull rod.

[0024] Embodiment

[0025] A layered pull rod three-dimensional storage shelf, referring to Figure 1, including a shelf body, which includes a frame 1, conveyor chains 2 arranged in parallel on both sides of the frame 1, and a driving component for driving the two conveyor chains 2 to rotate synchronously. A placement position for placing both ends of the product is formed between the conveyor chains 2, and several placement positions are arranged along the conveying direction. The shelf body is inserted in a stepped manner with at least two. In this embodiment, two shelf bodies are provided. The end at the conveying inlet is a fixed placement station for workpieces and the fixed placement station is in an exposed state. Along the conveying direction, several V-shaped blocks 4 with upward openings are arranged at intervals on the upper end surfaces of the two conveyor chains 2. The V-shaped blocks 4 on the two conveyor chains 2 are arranged in one-to-one correspondence, and the corresponding two V-shaped blocks 4 form a placement position.

[0026] In this embodiment, the distance between two corresponding V-shaped blocks 4 on the upper shelf body is greater than the distance between two corresponding V-shaped blocks 4 on the lower shelf body. And before the manipulator grabs the pull rod and places it into the shelf body, the length of the pull rod needs to be identified by a length identification sensor, and the identified result is fed back to the manipulator, so that the manipulator can place the longer pull rod into the upper shelf body and the shorter pull rod into the lower shelf body.

[0027] Reference Figures 1-4 , an auxiliary component for assisting the operator to quickly bundle all the workpieces placed on the shelf body is arranged on the two conveyor chains 2. The auxiliary component includes a pull rope (not shown in the figure) and a hook 9. The hook 9 is fixed on the opposite side of the conveyor chain 2. The hook 9 is arranged in one-to-one correspondence with the V-shaped block 4 and is located below the V-shaped block 4. One end of the pull rope is fixed on the hook 9 corresponding to the fixed placement station, and the other end of the pull rope is fixed on a fixed component located at the conveying inlet. In this embodiment, the end of the pull rope away from the hook 9 is fixed to the overhead crane.

[0028] Reference Figures 3-4 , the driving component includes a rotating shaft 5 rotatably arranged at both ends of the frame 1, transmission gears 3 coaxially fixed at both ends of the rotating shaft 5 and respectively meshed with a conveyor chain 2, and a driving member for driving one rotating shaft 5 to rotate. The driving member includes a motor 6 fixed on the frame 1. A driving wheel 7 is arranged on the output shaft of the motor 6. At a position opposite to the driving wheel 7 on the rotating shaft 5, a driven wheel 8 that can rotate following the driving wheel 7 and drive the rotating shaft 5 to rotate is arranged. In this embodiment, both the driving wheel 7 and the driven wheel 8 are sprockets 3, and the driving wheel 7 drives the driven wheel 8 to rotate through a toothed chain (not shown in the figure).

[0029] Specific steps: When the drawbar needs to be stored after production, first, fix the two ends of the drawstring to the hook 9 under the V-shaped block 4 at the conveying inlet of the conveyor chain 2 and on the overhead crane respectively. Then, identify the length of the drawbar through the length identification sensor and give feedback to the manipulator to control whether the manipulator needs to place the drawbar on the upper shelf body or the lower shelf body. After that, the manipulator grabs the drawbar and moves it above the fixed placement station. Then, the manipulator descends to place the drawbar into the V-shaped block 4 at the fixed placement station. After that, the motor 6 starts to drive the V-shaped block 4 and the hook 9 below the V-shaped block 4 to move, so that the V-shaped block 4 without a drawbar behind the V-shaped block 4 with a drawbar moves to the fixed placement station. Then the motor 6 stops. At this time, the manipulator can place the newly processed drawbar at the fixed placement station. The same applies subsequently, so that the drawbars can be placed into the shelf body in sequence. When the drawbar needs to be unloaded from the frame 1, at this time, the drawstring on the hook 9 under the V-shaped block 4 can be released, and the drawstring is pulled through under all the drawbars and fixed on the overhead crane. At this time, the overhead crane can remove all the drawbars on the frame 1.

[0030] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
