Description

Technical Field

[0001] This invention relates to the field of pipe manufacturing technology, and more specifically, to an automatic palletizing device for pipe manufacturing. Background Technology

[0002] In the pipe manufacturing industry, finished pipes typically need to be stacked in an orderly manner to facilitate subsequent storage, transportation, and further processing. Currently, the most common method for automated pipe stacking operations is to use robotic arms: the robotic arm picks up one or more pipes and moves them to a designated location for stacking.

[0003] However, the aforementioned robotic arm stacking method has obvious technical defects: on the one hand, the robotic arm's grasping, moving, and placing actions are relatively cumbersome, and the cycle time of a single stacking operation is long, resulting in low overall stacking efficiency and making it difficult to meet the needs of high-speed pipe production lines; on the other hand, the robotic arm can only achieve simple stacking of pipes and cannot effectively organize the pipes during the stacking process, which easily leads to problems such as pipe tilting, misalignment, and uneven stacking. This not only affects the stability of stacking but also requires subsequent manual intervention for secondary organization, increasing labor costs and further reducing production efficiency.

[0004] Therefore, in view of the problems of low efficiency and lack of pipe sorting effect of the existing robotic stacking method, there is an urgent need for an automated device that can achieve efficient stacking and simultaneous pipe sorting, so as to improve the overall automation level and production efficiency of pipe production. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide an automatic palletizing device for pipe production, which solves the technical problems of low efficiency and lack of pipe sorting effect in the prior art of robotic arm stacking of pipes.

[0006] According to one aspect, at least one embodiment of the present invention provides an automatic palletizing device for pipe production, comprising:

[0007] Guide rail bracket;

[0008] A storage box is mounted on the guide rail bracket. The top of the storage box has a first opening for the pipes to be stacked to enter the storage box.

[0009] A reciprocating pusher is disposed below the guide rail bracket and corresponds vertically to the storage box. The reciprocating pusher has a pusher rod capable of reciprocating up and down.

[0010] The bottom of the storage box is provided with a clearance groove, and the push rod can move upward through the clearance groove and push the pipes inside the storage box so that the pipes vibrate and stack.

[0011] Optionally, the storage box is slidably mounted on the guide rail bracket, and a pressing component is provided above the guide rail bracket and located above the storage box. The pressing component has a pressing plate that can move down and press the pipe, and the pressing plate can extend into the storage box through the first opening.

[0012] The pressing component and the reciprocating pushing component are arranged vertically and vertically, and the two form a sorting and stacking station; when the storage box is loaded with pipes, the storage box can slide along the guide rail bracket into the sorting and stacking station.

[0013] Optionally, the pressing component includes:

[0014] A fixed frame is located above the storage box;

[0015] The first lifting driver is disposed at the top of the fixed frame and has a downwardly extending movable end, and the pressing plate is fixedly disposed on the movable end of the first lifting driver.

[0016] Optionally, the storage box has entry slots on both side walls, the entry slots being horizontally continuous and extending upwards to the upper edge of the side wall of the storage box; the pressing assembly further includes:

[0017] A slide rail is provided on the fixed frame and is arranged along the sliding direction of the storage box;

[0018] A sliding plate is slidably mounted on the slide rail;

[0019] An electric actuator is mounted on the sliding plate. The movable end of the electric actuator is provided with a sorting block. The bottom surface of the sorting block is provided with a plurality of sorting grooves for positioning and cooperating with the outer wall of the pipe.

[0020] The electric push rod can move horizontally with the sliding plate closer to the storage box, so that the sorting block enters the storage box through the inlet slot and is positioned and sorted by means of the sorting slot.

[0021] Optionally, a second opening is provided on both end plates of the storage box, and a first pushing member corresponding to one of the second openings and a second pushing member corresponding to the other second opening are provided on the fixed frame. The first pushing member and the second pushing member can enter the storage box through the two second openings respectively to align the end face of the pipe.

[0022] Optionally, the movable end of the first pushing member is provided with a pushing block, the pushing block corresponding to one of the second openings, and the movable end of the second pushing member is provided with a baffle, the baffle facing the other second opening. The pushing block and the baffle can cooperate with each other to align the end face of the pipe located in the storage box; and when the baffle is opened, the pushing block can move the neatly stacked pipes out of the storage box through the second opening under the pushing action of the first pushing member.

[0023] Optionally, the second pusher includes:

[0024] An arc-shaped guide rail is disposed on the fixed frame and extends in an arc shape below the side near the second opening;

[0025] A deflection plate is hinged to the fixed frame. The deflection plate has a guide rod that is slidably disposed on the arc-shaped guide rail. The deflection plate can swing around the hinge axis under the limiting support of the arc-shaped guide rail.

[0026] A telescopic actuator is disposed on the deflection plate. The telescopic end of the telescopic actuator is provided with the baffle. The telescopic actuator can drive the baffle to move closer to or away from the second opening so that the baffle limits the end face of the pipe.

[0027] Optionally, there are multiple push rods and one-to-one corresponding clearance slots. The push rods extend horizontally and are arranged perpendicular to the sliding direction of the storage box. The reciprocating pusher includes:

[0028] The second lifting actuator has an upwardly extending movable end;

[0029] A support frame is provided on the movable end of the second lifting drive. Several push rods are spaced apart on the support frame. After the support frame moves up, it can cover the outer side of the storage box so that the push rods can enter the clearance groove.

[0030] Optionally, a roller sleeve is fitted on the push rod, and the roller sleeve can rotate around the push rod. When the first pusher pushes the neatly stacked pipes outward, the roller sleeve can support the sliding of the pipes.

[0031] Optionally, a guide plate is provided on the upper edge of the storage box, and a guide plate is also provided on the side edge of the second opening. The guide plate near the first opening is used to guide the pipes to be stacked into the storage box, and the guide plate near the second opening is used to guide the push block into the storage box.

[0032] The beneficial effects of this invention are as follows:

[0033] In this invention, during operation, the pipes to be stacked are first placed into the storage box. Then, the storage box is pushed along the guide rail bracket, moving it to the stacking position between the pressing assembly and the reciprocating pusher. At this time, the pressing assembly drives the pressing plate downwards, extending into the storage box through the opening at the top and pressing the pipes. It should be noted that when the pusher vibrates the pipes, the pressing plate must leave some space between itself and the topmost pipe. After a period of vibration, the pusher moves down out of the clearance groove and stops moving. During this time, the pressing plate moves down to lower the pipe groove. Then, the pusher reciprocates again to apply vibration to the pipes until they are neatly stacked.

[0034] The pressing component and the reciprocating pushing component work together to process the pipes. Compared with single pushing vibration, this method can more effectively organize the pipes and further improve the neatness and stability of the pipe stacking. The storage box can slide along the guide rail bracket to the sorting and stacking station, realizing flexible adjustment of the pipe stacking position. This facilitates the subsequent unified processing of neatly stacked pipes, further simplifies the operation process, improves the overall stacking efficiency, and better solves the problems of low stacking efficiency and poor sorting effect of existing robotic arms.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0048] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0049] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0052] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] like Figure 1 , Figure 2 and Figure 3 The diagram illustrates an automatic palletizing device for pipe production according to an embodiment of the present invention. The device includes a guide rail support 1, a storage box 2, and a reciprocating pusher 3. The storage box 2 is mounted on the guide rail support 1, and the top of the guide rail support 1 has a first opening 201 for the pipes to be stacked. The reciprocating pusher 3 is located below the guide rail support 1 and corresponds to the position of the storage box 2. The reciprocating pusher 3 has a pusher rod 301 that can move up and down reciprocally. The bottom of the storage box 2 has a clearance groove 203 that penetrates the bottom wall of the storage box 2 and extends inwards. After the pusher rod 301 moves upwards, it can pass through the clearance groove 203 and extend into the interior of the storage box 2.

[0054] In the above scheme, when stacking and organizing the pipes, the pipes to be stacked enter the storage box 2 through the first opening 201 at the top of the storage box 2. It should be noted that, if... Figure 10 As shown, the steel pipes to be stacked can be transported into the storage box 2 via a conveyor belt or by hoisting. Once the pipes enter the storage box 2, the reciprocating pusher 3 begins operation, driving the pusher rod 301 to move up and down reciprocally. During the upward movement of the reciprocating pusher 3, the pusher rod 301 can enter the clearance groove 203. This rapid, repeated pushing and vibration allows the pipes to be automatically aligned during vibration. Specifically, during its movement, the pusher rod 301 passes through the clearance groove 203 at the bottom of the storage box 2 and extends into the storage box 2, continuously and repeatedly pushing the bottom of the pipes inside the storage box 2. Through this reciprocating pushing action, the pipes vibrate, gradually aligning them during vibration.

[0055] Therefore, this application eliminates the need for cumbersome grasping, moving, and placing actions by robotic arms, simplifying the palletizing process, shortening the time for a single palletizing operation, and effectively improving overall palletizing efficiency. It can better meet the needs of high-speed pipe production lines. At the same time, the pipes are aligned by vibrating through the push rod 301, which can effectively organize the pipes during the palletizing process, avoiding problems such as pipe tilting and uneven stacking, ensuring the stability of the palletizing, eliminating the need for subsequent manual intervention for secondary organization, reducing labor costs, and further improving production efficiency.

[0056] For example, such as Figure 2 As shown, a pressing assembly 4 is provided above the guide rail bracket 1. The pressing assembly 4 is located above the storage box 2. The pressing assembly 4 is equipped with a pressing plate 401 that can move up and down. The pressing plate 401 can extend into the storage box 2 through the opening at the top of the storage box 2. The pressing assembly 4 and the reciprocating pushing member 3 located below the guide rail bracket 1 are arranged opposite each other in the vertical direction, forming a sorting and stacking station for sorting and stacking pipes. The storage box 2 can slide along the guide rail bracket 1 into this sorting and stacking station.

[0057] In the above scheme, specifically, the pipes to be stacked are first placed into the storage box 2, and then the storage box 2 is pushed to slide along the guide rail bracket 1, so that the storage box 2 moves to the sorting and stacking position between the pressing component 4 and the reciprocating push component 3. At this time, the pressing component 4 drives the pressing plate 401 to move downward. The pressing plate 401 extends into the storage box 2 through the opening at the top of the storage box 2 and presses the pipes. It should be noted that when the push rod 301 drives the pipes to vibrate, the pressing plate 401 should leave a certain space with the top layer of pipes. After a period of vibration, the push rod 301 moves down out of the clearance groove 203 and stops moving. During this period, the pressing plate 401 moves down to move the pipe groove down. Then the push rod 301 moves back and forth again to apply vibration to the pipes until the pipes are stacked neatly.

[0058] The pressing component 4 and the reciprocating pushing component 3 work together to process the pipes. Compared with single pushing vibration, this method can more effectively organize the pipes and further improve the neatness and stability of the pipe stacking. The storage box 2 can slide along the guide rail bracket 1 to the sorting and stacking station, realizing flexible adjustment of the pipe stacking position. This facilitates the unified processing of the neatly stacked pipes in the future, further simplifies the operation process, improves the overall stacking efficiency, and better solves the problems of low stacking efficiency and poor sorting effect of existing robotic arms.

[0059] Reference Figure 2 It should be noted that the guide rail bracket 1 includes a base and guide rails. At least two guide rails are provided, with a lead screw motor positioned between them. Stopping blocks are located at both ends of the guide rails to limit the maximum distance the storage box 2 can move. Specifically, two sliders are located at the bottom of the storage box 2, each corresponding to and slidably connected to a guide rail. A nut is fixedly installed in the center of the bottom surface of the storage box 2, connecting to the lead screw motor nut. The lead screw motor drives the storage box 2 to move horizontally on the guide rails. The bottom of the storage box 2 has grooves for the lead screw to pass through.

[0060] Furthermore, such as Figure 2 As shown, the pressing assembly 4 includes a fixed frame 402 and a first lifting actuator 403. The fixed frame 402 is fixedly mounted above the guide rail bracket 1 and positioned above the storage box 2. The first lifting actuator 403 is located inside the fixed frame 402, and the pressing plate 401 is fixedly mounted on the movable end of the first lifting actuator 403. When the first lifting actuator 403 drives the movable end to move, the pressing plate 401 can extend out of the bottom surface of the fixed frame 402 and extend into the storage box 2 through the opening at the top of the storage box 2. It should be noted that the pressing plate 401 is rectangular, and the width of the pressing plate 401 is adapted to the width of the inner wall of the storage box 2, and the length is preferably also adapted to the length of the storage box 2. This ensures that pipes of different lengths and quantities can be pressed and arranged.

[0061] In the above scheme, specifically, after the lead screw motor drives the storage box 2 to slide to the sorting and stacking station, the first lifting driver 403 is activated. The movable end of the first lifting driver 403 drives the pressing plate 401 to move downward. The pressing plate 401 gradually extends out of the bottom surface of the fixed frame 402, and continues to move downward until it enters the storage box 2 through the opening at the top of the storage box 2, until the pressing plate 401 contacts the pipes in the storage box 2 and applies appropriate pressure to press and sort the pipes. This process is intermittent with the process of pipe vibration. After the pipes are completely sorted and stacked, the movable end of the first lifting driver 403 drives the pressing plate 401 to move upward, so that the pressing plate 401 exits the storage box 2 and retracts into the fixed frame 402.

[0062] By using the fixed frame 402 as the mounting support for the first lifting driver 403 and the pressing plate 401, the structural stability of the pressing assembly 4 during operation is ensured. The first lifting driver 403 can precisely control the lifting stroke and pressing force of the pressing plate 401, avoiding damage to the pipes due to excessive pressing force or affecting the sorting effect due to insufficient pressing force. This improves the accuracy and reliability of pressing and sorting, further ensuring that the pipes are stacked neatly. It also increases the service life of the pressing assembly 4, reduces the probability of device failure, and indirectly improves the overall production efficiency.

[0063] Furthermore, for example, such as Figures 4-8 As shown, entry slots 204 are provided on both sides of the storage box 2. Two adjacent entry slots 204 on the two side walls are arranged opposite each other. The top of the entry slot 204 is open and connected to the inside of the storage box 2. The pressing assembly 4 also includes a slide rail 411, a sliding plate 412 and an electric push rod 413. The slide rail 411 is set on the side wall of the fixed frame 402. The sliding plate 412 is slidably mounted on the slide rail 411. The electric push rod 413 is vertically and vertically mounted on the sliding plate 412. The electric push rod 413 is provided with a sorting block 414. Several sorting slots 415 for sorting the pipes stacked in the storage box 2 are arranged at intervals on the bottom surface of the sorting block 414. The electric push rod 413 can drive the sorting block 414 to rise and fall. The electric push rod 413 can move with the sliding plate 412 towards the storage box 2, so that the sorting block 414 enters the storage box 2 through the entry slots 204.

[0064] When pipes of different heights are stacked in storage box 2, the height of the organizing block 414 is first adjusted by the electric actuator 413 to match the height of the pipe stack. Then, the sliding plate 412 is pushed to slide along the slide rail 411 towards storage box 2. The sliding plate 412 drives the electric actuator 413 and the organizing block 414 to move synchronously, so that the organizing block 414 enters storage box 2 through the entry groove 204 on the side wall of storage box 2. After the organizing block 414 enters, the organizing groove 415 on its bottom surface corresponds to and matches the pipes in storage box 2. During the sorting process, the sorting block 414 can move up and down reciprocally under the drive of the electric push rod 413, or it can move laterally reciprocally under the drive of the sliding plate 412. This multi-directional reciprocating movement positions and sorts the pipes, ensuring that the top layer of pipes are neatly arranged. It also functions as a pressing device for the pipes. This process can be performed immediately after the storage box 2 enters the stacking station, or it can be done intermittently with the pressing plate 401 after it has been pressed down, prioritizing the neat stacking of the pipes, and is not limited to the specific sequence of the pressing plate 401's actions. After sorting is complete, the sliding plate 412 drives the electric push rod 413 and the sorting block 414 out of the storage box 2, and the electric push rod 413 drives the sorting block 414 back to its original position.

[0065] Therefore, the electric push rod 413 can adjust the height of the sorting block 414 according to the height of the pipe layer, so that the device can adapt to the pipe stacking and sorting needs of different layer heights, thus improving the versatility of the device; the sorting groove 415 works with the pipe to achieve precise positioning and sorting, effectively solving the problem of unevenness that easily occurs when stacking multiple layers of pipes, and further improving the neatness of the pipe stacking; the cooperation between the sliding plate 412 and the slide rail 411 allows the sorting block 414 to flexibly enter and exit the storage box 2, which is convenient to operate, eliminates the need for manual sorting, reduces manpower input, and also avoids pipe damage that may be caused by manual sorting, ensuring pipe quality and stacking efficiency.

[0066] For example, such as Figure 6 As shown, the inner contour of the sorting groove 415 on the bottom surface of the sorting block 414 is adapted to the outer contour of the pipe to be stacked, and can fit with the outer surface of the pipe. The number and position of the sorting groove 415 correspond one-to-one with the top layer of pipes to be sorted and stacked in the storage box 2, that is, each pipe in the top layer can correspond to a sorting groove 415.

[0067] In the above scheme, after the sorting block 414 enters the storage box 2, the inner contour of the sorting groove 415 matches the outer contour of the pipe and corresponds one-to-one with the pipe. The sorting groove 415 will engage with the corresponding pipe. Through the limiting effect of the sorting groove 415 on the pipe, the offset pipe is adjusted to the correct position, ensuring that each pipe on the top layer is neatly arranged. At the same time, it can also ensure the alignment between the upper and lower layers of pipes, avoiding the problem of misalignment between layers. The matching of the sorting groove 415 with the outer contour of the pipe can fit the pipe tightly, improving the positioning and limiting effect of the pipe, preventing the pipe from sliding or shifting during the sorting process, and further ensuring the neatness of the pipe stacking. The one-to-one correspondence between the sorting groove 415 and the top layer of pipes ensures that each pipe in the top layer can be effectively sorted, solving the problem that some pipes cannot be sorted, making the entire stacking process more comprehensive and efficient. At the same time, it can also adapt to pipes of different specifications. As long as the inner contour of the sorting groove 415 matches the outer contour of the pipe, it can be used, thus expanding the applicability of the device.

[0068] For example, such as Figure 2 As shown, the storage box 2 has a second opening 202 at both ends. The fixed frame 402 has a first pusher 5 and a second pusher 6 at one end. The movable end of the first pusher 5 has a pusher block 51. The pusher block 51 is directly opposite one of the second openings 202 of the storage box 2 and can enter the storage box 2 through the second opening 202. The movable end of the second pusher 6 has a baffle 61. The baffle 61 is directly opposite the other second opening 202 of the storage box 2. The pusher block 51 and the baffle 61 can cooperate with each other. After the baffle 61 is opened, the pusher block 51 can push the neatly stacked pipes out of the corresponding second opening 202 of the storage box 2 under the push of the first pusher 5.

[0069] In the above scheme, when aligning the pipe ends, the baffle 61, under the action of the second pushing member 6, approaches the corresponding second opening 202 of the storage box 2, blocking one end of the pipe. Then, the first pushing member 5 pushes the pushing block 51 through the corresponding second opening 202 into the storage box 2. The pushing block 51 pushes the pipe towards the baffle 61 until the end faces of all the pipes are in contact with the baffle 61, achieving pipe end alignment. After the pipes are neatly stacked, the second pushing member 6 moves the baffle 61 away from the baffle. From the second opening 202, open the second opening 202 on one side of the storage box 2. Then, the first pushing member 5 pushes the pushing block 51 to push the neatly stacked pipes in the storage box 2 out of the corresponding second opening 202. It should be noted that the first pushing member 5 can slowly push out the neatly stacked pipes. For example, when the pipes are pushed out one-third of the second opening 202, stop pushing and tie the pipes. When two-thirds of the pipes are pushed out, stop pushing again and tie the pipes again.

[0070] The automatic alignment of the pipe end face is achieved through the cooperation of the push block 51 and the baffle 61, which solves the problem of easy misalignment of the pipe end face in the existing robotic arm stacking and further improves the stacking quality. After stacking, the pipe can be automatically pushed out of the storage box 2 without manual handling or robotic arm grabbing and moving, which simplifies the subsequent processing process, shortens the operation time, improves the overall production efficiency, and also reduces the safety hazards that may be caused by manual operation.

[0071] For example, such as Figure 9 As shown, the second pusher 6 includes an arc-shaped guide rail 62, a deflection plate 63, and a telescopic actuator 64. The arc-shaped guide rail 62 is located at the end of the fixed frame 402 and extends downward in an arc shape towards the side near the second opening 202. The deflection plate 63 is slidably mounted on the arc-shaped guide rail 62, and the position of the deflection plate 63 near the side wall of the fixed frame 402 is hinged to the fixed frame 402. The deflection plate 63 can rotate around the hinge axis and simultaneously achieve vertical swing under the limiting support of the arc-shaped guide rail 62. The telescopic actuator 64 is located on the deflection plate 63, and the baffle 61 is mounted on the movable end of the telescopic actuator 64. The telescopic actuator 64 can drive the baffle 61 to approach or move away from the second opening 202 of the storage box 2.

[0072] In the above scheme, when the baffle 61 needs to block the end face of the pipe, the deflection plate 63 first swings vertically around the hinge axis on the arc-shaped guide rail 62. It should be noted that the deflection action is driven by a motor and gears. Specifically, a gear is provided at the end of the hinge axis, the motor is mounted on the fixed frame, and a gear is also provided on the drive shaft of the motor. The two gears mesh, and when the motor starts, the motor can drive the hinge axis to rotate, and the hinge axis will drive the guide rod to slide along the arc-shaped guide rail. After deflection, the angle of the deflection plate 63 is adjusted to position the telescopic actuator 64 and the baffle 61 appropriately. Then, the telescopic actuator 64 drives the movable end to extend, causing the baffle 61 to approach the second opening 202 of the storage box 2 until the baffle 61 aligns with the second opening 202 and blocks the pipe end face. When it is necessary to open the baffle 61, the telescopic actuator 64 drives the movable end to retract, causing the baffle 61 to move away from the second opening 202. Then, the deflection plate 63 swings in the opposite direction around the hinge axis on the arc-shaped guide rail 62, causing the telescopic actuator 64 and the baffle 61 to swing together, further opening the passage of the second opening 202 and preventing obstruction of pipe extension. It can be understood that the telescopic actuator 64 can apply a pushing force to the baffle 61 to prevent it from being pushed open when the pipe is aligned. The distance between the baffle 61 and the second opening 202 can also be adjusted to accommodate pipes of different lengths.

[0073] The vertical swing of the deflection plate 63, combined with the telescopic action of the telescopic actuator 64, allows for flexible adjustment of the position and height of the baffle 61, adapting to storage boxes 2 and pipes of different specifications and placement positions, thus improving the adaptability and flexibility of the device. The arc-shaped guide rail 62 provides limiting support for the deflection plate 63, ensuring the stability of the deflection plate 63 during swing and preventing the baffle 61 from shaking during operation. This ensures that the baffle 61 can block or open smoothly, further improving the reliability of the device and ensuring the smooth alignment and ejection of the pipe ends.

[0074] For example, such as Figure 3 and Figure 9 As shown, there are several push rods 301 and several clearance slots 203, and each push rod 301 corresponds to a clearance slot 203. Each push rod 301 can pass through a corresponding clearance slot 203. The reciprocating push component 3 includes a second lifting drive 302 and a support frame 303. The second lifting drive 302 provides power for the lifting of the support frame 303. The support frame 303 is located on the movable end of the second lifting drive 302. Several push rods 301 are installed on the support frame 303 at intervals. After the support frame 303 moves upward, it can cover the outside of the storage box 2, so that all push rods 301 can enter the corresponding clearance slot 203 at the same time.

[0075] In the above scheme, when it is necessary to push and vibrate the pipes inside the storage box 2, the second lifting driver 302 drives the movable end to rise, causing the support frame 303 to move upward. The support frame 303 gradually covers the outside of the storage box 2. At the same time, each push rod 301 on the support frame 303 is aligned with a relief groove 203 at the bottom of the storage box 2. As the support frame 303 continues to rise, all push rods 301 simultaneously pass through the corresponding relief groove 203 and extend into the storage box 2. Subsequently, the second lifting driver 302 drives the movable end to move up and down reciprocally, causing the support frame 303 and the push rods 301 to move up and down together. The push rods 301 push the bottom of the pipes to achieve vibration and alignment of the pipes. After the alignment is completed, the second lifting driver 302 drives the movable end to descend, causing the support frame 303 and the push rods 301 to descend. The push rods 301 exit the relief groove 203, and the support frame 303 detaches from the outside of the storage box 2.

[0076] Several push rods 301 act simultaneously on the bottom of the pipe, ensuring uniform force distribution and preventing deformation or damage due to excessive force at a single point, thus guaranteeing pipe quality. The support frame 303 covers the outside of the storage box 2, serving two purposes: firstly, it positions the push rods 301, ensuring they accurately enter the clearance groove 203; secondly, it provides some fixation for the storage box 2, preventing it from shaking during the push vibration process and improving the stability of the device. The push rods 301 and clearance grooves 203 correspond one-to-one, further enhancing the uniformity of the push vibration, resulting in better pipe stacking and improved stacking quality and efficiency.

[0077] For example, such as Figure 3 As shown, a roller sleeve 304 is fitted on the push rod 301. The roller sleeve 304 can rotate freely around the push rod 301. When the first push member 5 pushes the neatly stacked pipes outward, the roller sleeve 304 contacts the bottom of the pipe and can support the sliding of the pipe.

[0078] In the above scheme, after the pipes are neatly stacked, the baffle 61 is opened, and the first pusher 5 pushes the pusher block 51 to push the pipes outward. Under the push of the pusher block 51, the pipes move along the inside of the storage box 2 towards the second opening 202. At this time, the bottom of the pipes contacts the roller sleeve 304 on the pusher rod 301. As the pipes move, the roller sleeve 304 rotates around the pusher rod 301, converting the sliding friction between the pipes and the pusher rod 301 into rolling friction, supporting the pipes to slide smoothly until the pipes are pushed out of the storage box 2 from the second opening 202.

[0079] The roller sleeve 304 effectively reduces the frictional resistance between the tube and the push rod 301, making the tube push out more smoothly and avoiding scratches or damage to the tube surface due to excessive frictional resistance, thus ensuring the appearance quality and performance of the tube. At the same time, the reduced frictional resistance also reduces the workload of the first push member 5, reduces the energy consumption and wear of the first push member 5, extends the service life of the first push member 5, reduces the maintenance cost of the device, and further improves the overall operating efficiency.

[0080] For example, such as Figure 3 As shown, guide plates 21 are provided on the storage box 2 at the upper edge near the first opening 201 at the top and at the side edges near the second openings 202 at both ends. The guide plate 21 near the first opening 201 is folded outward to guide the pipes to be stacked into the storage box 2; the guide plate 21 near the second opening 202 is also folded outward to guide the push block 51 of the first pusher 5 into the storage box 2.

[0081] In the above scheme, when the pipes to be stacked need to enter the storage box 2, the pipes move from the top of the storage box 2 toward the first opening 201. The guide plate 21 near the first opening 201 guides the pipes, guiding them to accurately enter the first opening 201 and fall into the storage box 2, avoiding collisions or jamming between the pipes and the edge of the opening of the storage box 2 during the entry process. When the first pusher 5 pushes the pusher block 51 into the storage box 2, the pusher block 51 moves toward the second opening 202. The guide plate 21 near the second opening 202 guides the pusher block 51 to accurately enter the second opening 202 and extend into the storage box 2, avoiding friction or collision between the pusher block 51 and the edge of the second opening 202.

[0082] The guide plate 21 makes the process of pipes entering storage box 2 and push block 51 entering storage box 2 smoother, avoiding problems such as jamming and collision, ensuring the continuity of operation and improving overall work efficiency; at the same time, it also reduces friction and collision damage between pipes and push block 51 and the opening edge of storage box 2, extends the service life of storage box 2, pipes and push block 51, reduces the maintenance cost of the device, and further improves the reliability of the device operation.
