Description

Technical Field

[0001] The present invention relates to the technical field of the transportation of bolted spherical grid members, and particularly relates to an automatic feeding device for bolted spherical grid members. Background Art

[0002] The bolted spherical grid members are the core load-bearing units in the bolted spherical grid structure, which are composed of steel pipes and the cones or cover plates welded at their ends.

[0003] A patent document with the publication number CN118164213B discloses a grid member production and assembly transportation device and a transportation method, including a frame and a conveyor belt. The frame is equipped with a transportation mechanism for driving the conveyor belt to move. A number of partition plates are fixedly connected to the outer wall of the conveyor belt. Above the frame, there is a feeding box, which is fixedly connected to the frame through a support frame. A discharge pipe located above the conveyor belt is fixedly connected to the feeding box. Below the discharge pipe, there is a first rotating shaft, and the frame is equipped with a driving unit for driving the first rotating shaft to rotate; two support disks are fixedly sleeved outside the first rotating shaft, and a number of receiving grooves are formed on the support disks for receiving the ends of the members. Two arc-shaped plates are fixedly installed on the discharge pipe, and the arc-shaped plates cooperate with the support disks.

[0004] However, the following problems still exist in this solution. When processing bolted spherical grid members, their surfaces need to be painted, and after painting, they need to be dried. During drying, the bolted spherical grid members usually need to be hung in a vertical state to avoid mutual collision between the bolted spherical grid members and improve the drying efficiency. After drying, the bolted spherical grid members are transported to a specified position, and at the same time, they need to be adjusted from a vertical state to a horizontal state during transportation for subsequent packing. In the above prior art, first, the suspended bolted spherical grid members need to be transported to the conveyor belt, and then the vertical bolted spherical grid members are adjusted to a horizontal state by manual and placed on the conveyor belt, which is a cumbersome process. Moreover, when the bolted spherical grid members are transported in a vertical state, they are prone to shaking and mutual collision, resulting in partial scratching and peeling of the paint. And when packing the members with different lengths and sizes after being placed horizontally, it is easy to cause the center of gravity to shift, affecting stacking and transportation. Summary of the Invention

[0005] The present invention provides an automatic feeding device for bolted spherical grid members, aiming to solve the problems in the related art that bolted spherical grid members with different lengths and sizes are prone to mutual collision and scratching due to instability during transportation and the center of gravity shifts during packing.

[0006] The automatic feeding device for bolt sphere grid members of the present invention includes a conveyor belt on a mounting frame. Sliding rails are assembled before and after on the conveyor belt. A first slider and a second slider are slidably assembled on the sliding rails. A guide rail is arranged on the side of the conveyor belt. One end of the guide rail slopes downward along the conveying direction of the members until it is flush with the conveyor belt. A connecting component connected to the members is arranged on the guide rail. The connecting component drives the members to move synchronously with the conveyor belt through the guide rail, and drives the members to move downward to cooperate with the first slider and the second slider in sequence. When the first slider moves away from the second slider, it drives the members to rotate to a horizontal state and then cooperate with the second slider. At the same time, the connecting component is separated from the members. Elastic members one are arranged at both ends of the sliding rails, and the elastic members one cooperate with the first slider and the second slider respectively to drive the center of the members to correspond to the center of the sliding rails.

[0007] The effect is that the connecting component is connected to the guide rail, and the connecting component drives the members to move through the guide rail. When the members move to the first slider, its lower end cooperates with the first slider through the limiting component, and at the same time releases the restriction on the first slider. The conveyor belt drives the first slider and the second slider to move through the sliding rails. The connecting component drives the members to move synchronously with the sliding rails. At the same time, the first slider slides away from the second slider until the upper end of the members is placed on the second slider and cooperates with the limiting component on the second slider to release the restriction on the second slider. Then the elastic members one cooperate with the first slider and the second slider respectively, so that the first slider and the second slider receive the same force, driving the center of the members to move to correspond to the center of the sliding rails, reducing the phenomenon of center of gravity deviation, so as to facilitate packing and subsequent stacking and transportation. At the same time, the connecting component drives the members to move synchronously with the conveyor belt, reducing the phenomenon of mutual collision of the members during transportation and reducing damage to the members.

[0008] Preferably, limiting components are arranged on both the first slider and the second slider. The limiting components are connected to the sliding rails to fix the first slider and the second slider. An elastic member two is arranged between the first slider and the second slider. The elastic member two is connected to the first slider or the second slider. When the first slider and the second slider are in contact, the elastic member two is in a compressed state. The members cooperate with the first slider or the second slider through the limiting components. The members cooperate with the limiting components to release the restrictions on the first slider or the second slider in sequence. After releasing the restriction on the first slider, the elastic member two pushes the first slider away from the second slider.

[0009] The effect is that after the limiting component releases the restriction on the first slider, the elastic member two drives the first slider to move away from the second slider, making the members in an inclined state, so that while the members move with the connecting component, they gradually rotate to a horizontal state under their own gravity.

[0010] Preferably, the limiting component includes a pressing plate, a connecting plate, an elastic member III, and a clamping block. The pressing plate is slidably assembled up and down on the first slider. An installation groove is formed in the first slider. The clamping block is assembled up and down in the installation groove. The clamping block is connected to the pressing plate through the connecting plate. A first clamping groove is formed on the slide rail. The clamping block slides upward to engage with the first clamping groove to fix the first slider. The elastic member III cooperates with the clamping block to drive the clamping block to engage with the first clamping groove. When the rod member is placed on the first slider, it cooperates with the pressing plate and presses the pressing plate downward. The movement of the pressing plate drives the clamping block to separate from the first clamping groove.

[0011] The effect is that the rod member cooperates with the pressing plate and drives the pressing plate to move. The movement of the pressing plate drives the clamping block to move through the connecting plate, so that the clamping block separates from the first clamping groove, releasing the restriction on the first slider, and enabling the first slider to move relative to the slide rail.

[0012] Preferably, the connecting component includes a connecting seat, a lifting ring, a connecting block, a clamping rod, and an elastic member IV. The connecting seat is connected to the guide rail. The lifting ring is connected to the connecting block and the connecting seat respectively. There are two clamping rods, and both clamping rods are slidably arranged on the connecting block. A buckling portion is provided at the lower end of the clamping rod. The elastic member IV is arranged in the clamping rod and connected to the clamping rod for driving the buckling portion to buckle on the end of the rod member.

[0013] The effect is that the connecting seat drives the clamping rod to move through the lifting ring and the connecting block. The clamping rod suspends the rod member through the buckling portion and drives the rod member to move at the same time.

[0014] Preferably, the two clamping rods are symmetrically arranged around the center of the rod member. The sliding directions of the two clamping rods are parallel to each other. An inclined block is provided on the side of the clamping rod. A sliding sleeve is slidably engaged with the inclined block on the outside of the clamping rod. The sliding sleeve cooperates with the inclined block at different positions to drive the two clamping blocks to approach each other, so that the buckling portion separates from the rod member. A top rod is provided on the mounting frame. An inclined surface II is formed on the side of the top rod close to the sliding sleeve. The inclined surface II abuts against the side of the sliding sleeve to drive the sliding sleeve to move.

[0015] The effect is that after the rod member rotates to the horizontal state, the sliding sleeve abuts against the inclined surface II of the top rod. The top rod drives the sliding sleeve to move. The sliding sleeve drives the two clamping rods to approach each other through the inclined block until the buckling portion separates from the rod member, and the rod member is conveyed only by the conveyor belt for subsequent position adjustment.

[0016] Preferably, a connecting shaft is arranged in the connecting seat. The lifting ring is rotatably assembled on the connecting shaft. A limiting frame and an elastic member V are arranged on the connecting seat. The limiting frame is slidably assembled up and down on the connecting seat. The elastic member V is connected to the limiting frame for driving the limiting frame to move upward. A horizontal portion is arranged on the guide rail. An inclined plate is arranged in the horizontal portion. The movement of the connecting seat drives the limiting frame to abut against the inclined plate. The limiting frame moves to the outside of the lifting ring, and the lifting ring rotates between the limiting frames to place the rod member in the horizontal state.

[0017] The effect is that the limiting frame moves past the inclined plate, causing the limiting frame to move outside the hanging ring, restricting the hanging ring so that the hanging ring can only rotate around the connecting shaft and drive the rod to rotate to the horizontal state.

[0018] Preferably, a stabilizing belt is rotatably arranged on the mounting frame. A stabilizing groove is formed on the outer side of the stabilizing belt. The stabilizing belt is arranged below the horizontal part. When the connecting seat moves in the horizontal part, the rod is engaged with the stabilizing groove.

[0019] The effect is that the cooperation between the stabilizing groove and the rod reduces the phenomenon of the rod shaking during transportation, so that the rod can cooperate with the first sliding seat.

[0020] Preferably, a reset rod is arranged at the bottom of the mounting frame. The two ends of the reset rod are respectively arranged obliquely near the two sides of the conveyor belt. One end of the reset rod is arranged at an interval from the side surface of the conveyor belt. After the conveyor belt drives the first slider and the second slider to rotate to the bottom of the mounting frame, they are in sliding contact with the reset rod. The reset rod drives the first slider to move to the first clamping groove so that the clamping block is engaged with the first clamping groove.

[0021] The effect is that after the first slider and the second slider are separated from the rod, the reset rod drives the first slider and the second slider to move to the initial position, so as to cooperate with the rod again to convey it.

[0022] Preferably, a first inclined surface is provided on the side of the clamping block in the first slider close to the second slider. The shape of the clamping block in the second slider is the same as that of the clamping block in the first slider.

[0023] The effect is that when the first slider and the second slider are reset, the clamping block on the second slider can move past the first clamping groove through the first inclined surface, reducing the phenomenon that the clamping block interferes with the movement of the second slider to the initial position.

[0024] Preferably, a second clamping groove is formed on the slide rail. The clamping block in the second slider is engaged with the second clamping groove. When the clamping block is engaged with the second clamping groove, the second slider compresses the first elastic member.

[0025] The effect is that the clamping block on the second slider is engaged with the second clamping groove to restrict the second slider. At the same time, the first elastic member is compressed. After the cooperation between the rod and the second slider releases the restriction on the second slider, the first elastic member pushes the second slider to correct the position of the rod.

[0026] Beneficial effects:

[0027] When the rod of the present invention is suspended and transported, through the cooperation between the stabilizing belt and the rod, and the cooperation between the limiting frame and the hanging ring, the phenomenon of the rod shaking is reduced. And when the rod rotates to the horizontal state, the connecting seat drives the rod to move synchronously with the conveyor belt. After the rod cooperates with the first slider and the second slider, the first elastic member drives the first slider and the second slider to move. Since the first slider and the second slider are subjected to the same force, the two first elastic members drive the center of the rod to move to correspond to the center of the slide rail, reducing the phenomenon of the center of gravity shifting during packing, so as to facilitate stacking and transportation.

Detailed Description of the Embodiment

[0039] The following describes in detail the embodiments of the present invention, and the examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] As Figures 1 to 9 shown, the automatic feeding device for bolt ball grid frame members of the present invention includes a conveyor belt 2, a guide rail 3, a connecting component 4, and a supporting component assembled on a mounting frame 1. The conveyor belt 2 is horizontally placed, and the guide rail 3 is arranged on one side of the conveyor belt 2. The guide rail 3 is arranged along the conveying direction of the conveyor belt 2. One end of the guide rail 3 is inclined downward along the conveying direction of the member 01, so that one end of the guide rail 3 is flush with the conveyor belt 2. The member 01 is connected to the connecting component 4, and the supporting component is arranged on the conveyor belt 2.

[0041] Under the action of the inclined guide rail 3, the connecting component 4 drives the member 01 to move downward while moving, until the lower end of the member 01 moves downward to cooperate with the supporting component. The connecting component 4 moves synchronously with the conveyor belt 2. While the member 01 is conveyed by the conveyor belt 2, it gradually rotates from a vertical state to a horizontal state, and then the connecting component 4 is separated from the member 01, and the member 01 is conveyed to the next process for packing through the conveyor belt 2.

[0042] Referring to Figure 1 , multiple sets of the connecting component 4 and the supporting component are provided to convey multiple members 01 simultaneously, improving the conveying efficiency of the members 01.

[0043] Referring to Figure 2 , Figure 3 , Figure 4 , the supporting component includes: slide rails 5 assembled on the conveyor belt 2 front and back, a first slider 6 and a second slider 7 slidably matched with the slide rails 5, a limiting component 8, and a first elastic member 9. The slide rails 5 are arranged along the direction perpendicular to the conveying direction of the conveyor belt 2. The first slider 6 and the second slider 7 are slidably arranged on the slide rails 5 along the length direction of the slide rails 5. The limiting component 8 is respectively arranged on the first slider 6 and the second slider 7, and the limiting component 8 is used to fix the first slider 6 and the second slider 7 on the slide rails 5. The first elastic member 9 is set as a spring, and the first spring is arranged on the slide rails 5, and two first elastic members 9 are arranged at both ends of the slide rails 5.

[0044] In the initial state, slider one 6 and slider two 7 are in contact, and both slider one 6 and slider two 7 are placed close to the guide rail 3. Slider two 7 is in contact with and compresses elastic member one 9. The limiting component 8 fixes slider one 6 and slider two 7 on the slide rail 5 respectively. While the connecting component 4 drives the rod 01 to move along with the guide rail 3, the rod 01 moves downward. The lower end of the rod 01 moves to cooperate with slider one 6, and at the same time cooperates with the limiting component 8 to release the restriction on slider one 6. Then slider one 6 slides away from slider two 7, causing the rod 01 to gradually rotate to a horizontal state until the other end of the rod 01 rotates to the position of slider two 7 and cooperates with the limiting component 8 on slider two 7 to release the restriction on slider two 7. At this time, the connecting component 4 is separated from the rod 01. Slider one 6 moves to the elastic member one 9 at the other end of the slide rail 5. Slider one 6 and slider two 7 cooperate with the two elastic members one 9 respectively. Under the action of the elastic member one 9, the centers of the respective rods 01 correspond to the center of the slide rail 5, reducing the phenomenon of center of gravity deviation during subsequent packaging.

[0045] If the lengths of the rods 01 are different, as the connecting component 4 continues to move, the rod 01 will still cooperate with the corresponding slider one 6 successively. After the rod 01 is separated from the connecting component 4, the center of gravity of the rods 01 with different lengths can also be adjusted to the same straight line through the elastic member one 9 for subsequent packaging.

[0046] Refer to Figure 1 , the bottom of the guide rail 3 is arranged obliquely in the direction away from the conveyor belt 2, so that the upper end of the rod 01 can cooperate with slider two 7 when rotating to the horizontal position.

[0047] Refer to Figure 2 , an elastic member two 61 is arranged between slider one 6 and slider two 7. The elastic member two 61 is set as a spring, and the spring is connected to slider one 6 or slider two 7. In this embodiment, the elastic member two 61 is set to be connected to slider one 6. When slider one 6 and slider two 7 are in contact, the elastic member two 61 is in a compressed state. After the end of the rod 01 cooperates with slider one 6 and releases the restriction on slider one 6, the elastic member two 61 pushes slider one 6 away from slider two 7, and at the same time drives the rod 01 to rotate to an inclined state, so that the rod 01 rotates in a specified direction, so that the rod 01 gradually rotates to a horizontal state as the connecting component 4 moves.

[0048] The cooperation mode of the limiting component 8 with slider one 6 and slider two 7 is the same.

[0049] Refer to Figure 2 , Figure 3, the limiting component 8 includes a pressing plate 81, a connecting plate 82, a third elastic member 83, and a clamping block 84. An installation groove 62 is formed in the first slider 6, and a first clamping groove 51 is formed on the slide rail 5. The clamping block 84 is slidably assembled up and down in the installation groove 62. The pressing plate 81 is arranged on the side of the first slider 6 close to the rod 01. The connecting plate 82 is arranged between the clamping block 84 and the pressing plate 81 and connects the two. The third elastic member 83 is a spring. The third elastic member 83 is arranged in the installation groove 62 and connected to the clamping block 84. The third elastic member 83 drives the clamping block 84 to move upward to engage with the first clamping groove 51 to fix the first slider 6.

[0050] In the initial state, the clamping block 84 engages with the first clamping groove 51 to fix the first slider 6. The rod 01 cooperates with the first slider 6 through the pressing plate 81. The rod 01 and the pressing plate 81 cooperate to drive the pressing plate 81 to move downward. The pressing plate 81 drives the clamping block 84 to move downward through the connecting plate 82 to separate from the first clamping groove 51 to release the restriction on the first slider 6.

[0051] Refer to Figure 2 , a second clamping groove 52 is formed on the slide rail 5. The second clamping groove 52 is correspondingly arranged with the second slider 7. The clamping block 84 on the second slider 7 engages with the second clamping groove 52 to fix the second slider 7. When the end of the rod 01 away from the first slider 6 cooperates with the pressing plate 81 on the second slider 7, the restriction on the second slider 7 is released.

[0052] Refer to Figure 5 , a reset rod 11 is arranged at the bottom of the mounting frame 1. The reset rod 11 is arranged along the conveying direction of the conveyor belt 2, and both ends of the reset rod 11 are respectively close to both sides of the conveyor belt 2, so that the reset rod 11 is in an inclined state, and one end of the reset rod 11 is arranged at an interval from the side surface of the conveyor belt 2.

[0053] The conveyor belt 2 drives the rod 01 to move through the slide rail 5, the first slider 6, and the second slider 7, and conveys the rod 01 to the next process for packing. After the rod 01 is separated from the conveyor belt 2, the conveyor belt 2 drives the first slider 6 and the second slider 7 to rotate to the bottom of the mounting frame 1. At the same time, the first slider 6 cooperates with the inclined side of the reset rod 11. As the conveyor belt 2 continues to rotate, the reset rod 11 drives the first slider 6 to move towards the second slider 7 until the clamping block 84 on the first slider 6 engages with the first clamping groove 51, and the clamping block 84 on the second slider 7 engages with the second clamping groove 52, driving the first slider 6 and the second slider 7 to move to the initial position for conveying the rod 01 again.

[0054] Refer to Figure 2, a first inclined surface 841 is formed on the clamping block 84 inside the first slider 6. The first inclined surface 841 is arranged on the side of the clamping block 84 facing the second slider 7. The shape of the clamping block 84 on the second slider 7 is the same as that of the clamping block 84 inside the first slider 6, that is, the first inclined surface 841 is provided on the same side of the two clamping blocks 84. When the first slider 6 moves to the initial position, the clamping block 84 on the second slider 7 can be separated from the first clamping groove 51 through the first inclined surface 841, reducing the phenomenon that the clamping block 84 on the second slider 7 interferes with the movement of the first slider 6 and the second slider 7.

[0055] Refer to Figure 6 , Figure 7 , Figure 8 , the connecting component 4 includes a connecting seat 41, a lifting ring 42, a connecting block 43, a clamping rod 44, and a fourth elastic member 45. The connecting seat 41 is connected to the guide rail 3, the lifting ring 42 is connected to the connecting seat 41, and the connecting block 43 is connected to the lifting ring 42, that is, the connecting block 43 is connected to the connecting seat 41 through the lifting ring 42. There are two clamping rods 44, and the clamping rods 44 are arranged in the vertical direction. The two clamping rods 44 are slidably arranged on the connecting block 43. A clamping portion 443 is provided at the lower end of the clamping rod 44. The fourth elastic member 45 is arranged as a spring. There are two fourth elastic members 45, and the two fourth elastic members 45 are respectively connected to the two clamping rods 44. The fourth elastic member 45 is connected to the clamping rod 44 to drive the two clamping rods 44 to move away from each other. The end of the clamping rod 44 is inserted into the rod member 01, and the fourth elastic member 45 drives the clamping portion 443 to engage with the inside of the rod member 01 and connect with the rod member 01 to hang the rod member 01, so that the rod member 01 can move with the connecting seat 41.

[0056] A driving wheel and a motor that cooperate with the guide rail 3 are arranged on the connecting seat 41. The motor is arranged on the connecting seat 41. The driving wheel cooperates with the guide rail 3. The driving wheel is arranged at the output end of the motor. The motor drives the driving wheel to rotate, thereby driving the connecting seat 41 to move and adjusting the position of the rod member 01.

[0057] Refer to Figure 6 , Figure 7 , the two clamping rods 44 are symmetrically arranged about the center of the rod member 01, and the sliding directions of the two clamping rods 44 are parallel to each other, that is, the clamping rods 44 will not interfere with each other during sliding. Oblique blocks 441 are arranged on the sides of the two clamping rods 44. A sliding sleeve 442 is slidably arranged outside the clamping rod 44. The sliding sleeve 442 cooperates with the oblique block 441. The sliding sleeve 442 cooperates with different positions of the oblique block 441 to drive the clamping rods 44 to approach each other until the clamping portion 443 is separated from the rod member 01. A top rod 12 is arranged on the mounting frame 1. A second inclined surface 121 is formed on the side of the top rod 12 close to the sliding sleeve 442.

[0058] After the rod 01 rotates to the horizontal state, that is, after the two ends of the rod 01 are respectively placed on the first slider 6 and the second slider 7, the sliding sleeve 442 moves to cooperate with the second inclined surface 121 of the ejector rod 12. With the continuous movement of the sliding sleeve 442, the sliding sleeve 442 is driven to move through the second inclined surface 121, and then the clamping rod 44 is driven to move, so as to separate the clamping rod 44 from the rod 01.

[0059] Refer to Figure 8 , a connecting shaft 411 is arranged in the connecting seat 41, and the lifting ring 42 is rotationally matched with the connecting shaft 411. A limiting frame 412 is arranged on the connecting seat 41. The bottom of the limiting frame 412 is provided with an opening. The limiting frame 412 is slidably assembled up and down on the connecting seat 41, and the limiting frame 412 is arranged above the lifting ring 42. A fifth elastic member 413 for connecting the two is arranged between the limiting frame 412 and the connecting seat 41. The fifth elastic member 413 is set as a spring, and the fifth elastic member 413 is used to drive the limiting frame 412 to move upward. A horizontal portion 31 is arranged on the guide rail 3, and an inclined plate 32 is arranged on the top of the horizontal portion 31.

[0060] When the connecting seat 41 moves past the inclined plate 32, the limiting frame 412 moves to abut against the inclined plate 32, driving the limiting frame 412 to move downward. The limiting frame 412 moves to the outside of the lifting ring 42 through the opening at its bottom. When the connecting seat 41 moves to other positions of the guide rail 3, the limiting frame 412 always abuts against the inner wall of the guide rail 3 to limit the lifting ring 42, so that the lifting ring 42 can only rotate around the connecting shaft 411. The rod 01 rotates around the connecting shaft 411 to the horizontal state. Through the cooperation of the limiting frame 412 and the lifting ring 42, the phenomenon of the rod 01 shaking when rotating to the horizontal state is reduced, and its stability is improved.

[0061] Refer to Figure 1 , Figure 9 , a stabilizing belt 13 is arranged on the mounting frame 1. The stabilizing belt 13 is set as a conveyor belt 2. The side surface of the stabilizing belt 13 corresponds to the side surface of the conveyor belt 2, that is, the rotation axis of the stabilizing belt 13 is arranged in the vertical direction. The stabilizing belt 13 is arranged on one side of the conveyor belt 2. A stabilizing groove 131 is opened on the stabilizing belt 13. The stabilizing belt 13 is arranged below the horizontal portion 31. After the limiting frame 412 cooperates with the lifting ring 42, the side surface of the rod 01 cooperates with the stabilizing groove 131. At the same time, the stabilizing belt 13 rotates synchronously with the movement of the rod 01 to support the rod 01, reducing the phenomenon of the rod 01 shaking, so that the rod 01 can cooperate with the first slider 6 when moving to the first slider 6. After the lower end of the rod 01 cooperates with the first slider 6, the stabilizing belt 13 rotates to drive the stabilizing groove 131 to separate from the rod 01. In addition, magnets can be arranged on the inner wall of the stabilizing groove 131 to adsorb the side surface of the rod 01, further improving the stability of the rod 01.

[0062] The implementation principle of the present invention is as follows: The connecting seat 41 suspends the rod 01 to move. At the same time, the stabilizing belt 13 drives the stabilizing groove 131 cooperating with the rod 01 to move synchronously. When the rod 01 moves to the first slider 6, the rod 01 drives the pressing plate 81 to move downward. The movement of the pressing plate 81 drives the clamping block 84 to separate from the first clamping groove 51, releasing the restriction on the first slider 6. As the connecting seat 41 continues to move, the second elastic member 61 drives the first slider 6 to move away from the second slider 7 by a certain distance, making the rod 01 in an inclined state. When the connecting seat 41 continues to move, the rod 01 can continue to rotate along this inclined direction under the action of its own gravity, and at the same time, it pushes the first slider 6 to move until the other end of the rod 01 is placed on the second slider 7, releasing the restriction on the second slider 7. At this time, the second inclined surface 121 of the ejector rod 12 cooperates with the sliding sleeve 442 to drive the sliding sleeve 442 to move, so that the clamping rod 44 separates from the rod 01. The first slider 6 and the second slider 7 drive the clamping rod 44 to move to correspond to the center of the slide rail 5 under the action of the first elastic member 9, so that the centers of multiple rods 01 are on the same straight line when they rotate to the horizontal state, facilitating stacking and transportation.

[0063] In addition, for rods 01 with different length dimensions, they continuously descend during the conveying process until they cooperate with the designated first slider 6. And under the action of the first elastic member 9, the centers of rods 01 with different lengths can be adjusted to correspond to the center of the slide rail 5 for subsequent packing.

[0064] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
