Description

Technical Field

[0001] This invention relates to the field of mechanical packaging technology, specifically to a combined packaging and palletizing equipment for cylindrical materials in a factory. Background Technology

[0002] With the improvement of industrial automation and the development of logistics, in order to achieve full automation of production lines and improve production efficiency, automatic packaging and palletizing equipment is now widely used on production lines to package, sort and palletize products. Automatic packaging and palletizing equipment uses sensors to detect the position and status of items, and the control system directs the mechanical structure to perform gripping, handling and palletizing operations according to a preset program.

[0003] In industrial applications, automated packing and palletizing machinery is primarily used for stacking rectangular objects. Stacking cylindrical items largely relies on manual labor or the use of simple molds. Currently, equipment available for stacking cylindrical materials typically employs vertical drop or clamping methods for boxing, bagging, or wrapping, and can only process a single item or a single layer at a time. Because cylinders are prone to rolling, items in the second layer often slip into the gaps between items in the first layer, resulting in the second layer holding one less item than the first. This not only increases the space utilization of the packaging box or bag but also limits its ability to handle small items. Furthermore, it suffers from slow speed, low precision, and significant material loss. Existing technologies have proposed good solutions, such as the cylindrical item palletizing device with patent publication number CN105110022B. This device uses a pushing cylinder to move the material, and a pushing pressure plate and tension spring on the pushing mechanism ensure the stability of the material during lifting and pushing. Simultaneously, guide plates and guide strips set in the pushing direction of the pushing mechanism evenly separate the material, preventing rolling, accumulation, and collisions during palletizing and lifting. Moreover, the palletizing box structure with a fence-like middle partition effectively prevents cylindrical items from tipping over during palletizing, thus avoiding impacts on storage and transportation quality.

[0004] While existing technologies have solved the problem of cylindrical materials easily collapsing during storage and stacking, the following issues remain: Although the specifications and models of cylindrical materials are limited, the demand for different lengths results in a wide variety of cylindrical materials. Designing a dedicated packing and stacking rack for each type of cylindrical material would not only be a huge undertaking but also prone to confusion in actual use, affecting production efficiency. Furthermore, the molds occupy production space. Existing packing and stacking rack designs are relatively generic; for cylindrical materials of various specifications (such as Φ159, Φ89, Φ108, etc.), due to the unequal outer diameters, using a generic stacking rack results in irregular stacking, poor strapping tightening, and a tendency for collapse, thus affecting storage and transportation quality.

[0005] In view of the above, in order to overcome the above technical problems, the present invention provides a combined packaging and palletizing equipment for cylindrical materials in factories. Summary of the Invention

[0006] This invention provides a combined packaging and palletizing equipment for cylindrical materials in factories, which solves the problem that general stacking racks cannot form a regular shape when stacking cylindrical materials of different numbers and sizes, resulting in poor packaging effect and affecting storage and transportation. By designing the stacking rack as a freely adjustable structure, setting a fixing mechanism to distinguish and buffer the stacking of each layer of materials, and setting an adjustment mechanism to shape and support the bottom cylindrical materials, the invention ensures that the cylindrical materials are stacked regularly and form a stable support.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A combined packing and palletizing device for cylindrical materials in a factory includes a transport mechanism and a gripping mechanism; it also includes a stacking frame, a fixing mechanism, and an adjusting mechanism; the stacking frame is connected to the gripping mechanism; the fixing mechanism is connected to the stacking frame; the adjusting mechanism includes an adjusting hole and an adjusting plate; the adjusting hole is formed on the fixing mechanism; the adjusting plate is connected to the fixing mechanism; the gripping mechanism grips the cylindrical material to the stacking frame position, the fixing mechanism on the stacking frame receives the cylindrical material and slowly moves it down to the adjusting mechanism position, the adjusting hole slides open under the pressure of the cylindrical material and then contracts to press the cylindrical material, and the adjusting plate is pressed and limited by the pressure of the outermost cylindrical material to limit the adjusting hole.

[0009] Preferably, the fixing mechanism includes a fixing plate, a separating groove, a separating slider, a separating spring, and a connecting assembly; the separating groove is formed on the inner wall of the fixing plate; a plurality of separating sliders are slidably installed in the separating groove; the separating springs are installed at intervals with the separating sliders; and the connecting assembly is connected between the separating sliders and the adjusting mechanism.

[0010] In the above scheme, multiple separation sliders are installed on the side wall of the fixed plate. The separation sliders of each layer are at the same angle to the side wall of the fixed plate. When each layer of cylindrical material is lowered, the outermost cylindrical material will contact the side wall of the fixed plate when it reaches the bottom position. At this time, the bottommost separation slider will contact the outermost cylindrical material. Thus, when the cylindrical material is stacked, it is clearly layered under the action of the separation sliders. Furthermore, due to the action of the separation spring, the lowering of the cylindrical material is buffered, avoiding impact on the bottom cylindrical material and preventing collapse.

[0011] Preferably, the fixing plate includes a base plate and a support plate; the base plate is connected to the stacking rack; the support plate is connected to the base plate, and the included angle between the base plate and the support plate is 120 degrees.

[0012] In the above scheme, cylindrical materials are usually stacked into a hexagonal structure to ensure stability and reduce space occupation during stacking. The interior angle of the hexagonal structure is 120 degrees. Therefore, the base plate and support plate are fixed as a 120-degree structure, which can provide good support for the stacked cylindrical materials, so that the stack can be formed. This allows the outer cylindrical materials to make tangential contact with the support plate, so that each cylindrical material in the outer ring can be supported, thereby ensuring the stability of the stacking structure.

[0013] Preferably, the adjusting hole includes an adjusting groove, an adjusting slider, and an adjusting spring; the adjusting groove is symmetrically opened on both sides of the base plate; multiple adjusting sliders are slidably installed in the adjusting groove; and the adjusting spring is installed at intervals with the adjusting slider.

[0014] In the above scheme, the adjustment hole is set to be automatically adjustable in size, which can accommodate cylindrical materials with different hole diameters. The distance between two adjustment sliders can be adjusted by adjusting the spring force, so that after the cylindrical material is placed between the two adjustment sliders, the spring force is adjusted to clamp the cylindrical material, thereby ensuring that the cylindrical material will not shake, increasing the stability of the bottom stacking, ensuring that it can be stacked and formed in the future, and adapting to cylindrical materials with different diameter specifications.

[0015] Preferably, the upper part of the adjusting slider is symmetrically provided with a fitting arc surface; the fitting arc surface is made of rubber, and when clamping the cylindrical material, the center of the arc of the fitting arc surface is set off-center from the center of the cylindrical material cross-section.

[0016] In the above solution, the rubber-coated curved surface further improves the stability of the bottom cylindrical material after clamping and fixing. The rubber material can deform to a certain extent under clamping force, maintaining its contact with the cylindrical material. The rubber material increases friction without causing wear on the cylindrical material surface, thus preventing radial sliding under clamping force. Since the radius of curvature of the curved surface is greater than the radius of the cylindrical material, to ensure that the curved surface increases the contact area with the cylinder, the center of the curved surface cross-section is offset from the center of the cylindrical material cross-section when clamping the cylindrical material. This results in better fixing of each bottom cylindrical material, improving stability.

[0017] Preferably, the adjusting spring is provided with threaded seats at both ends, and the elastic modulus of the adjusting spring first decreases and then increases along the axial direction; the adjusting slider is provided with threaded holes on both sides that cooperate with the threaded seats.

[0018] In the above solution, the adjusting spring and adjusting slider are set as detachable structures, so that the number of adjusting sliders and adjusting springs can be adjusted according to the actual stacking requirements. This design allows for quick conversion of the work site without frequent tooling changes, thus adapting to different quantities and specifications of cylindrical materials.

[0019] Preferably, the adjusting plate includes an adjusting plate body and adjusting legs; the adjusting plate body includes a rotating part and a bending part; the adjusting legs are connected to the stacking rack; the rotating part is connected to the adjusting legs; the bending part can be freely engaged with the adjusting slider.

[0020] In the above scheme, when the cylindrical material on the side presses against the rotating part, it provides a torque to the rotating part, thereby causing the bent plate to generate a flipping torque. Under the action of the flipping torque, the bent plate will exert an upward pressure on the adjusting slider, so that both the adjusting slider and the bent plate can remain stable, increasing the friction and preventing them from sliding horizontally. As the stacking weight increases, the upward pressure and friction will increase accordingly, thus maintaining the stability of the stacking structure. Furthermore, the bent plate can be freely engaged between the two adjusting sliders, making the disassembly and assembly of the structure more flexible and suitable for cylindrical materials of various quantities and specifications, further improving its practicality.

[0021] Preferably, the separating slider includes a limiting plate, a separating rotating block, a shrinking block, and a shrinking spring; the limiting plate is slidably installed in the separating groove; the separating rotating block is rotatably installed on the limiting plate, and a shrinking groove is formed on the separating rotating block; the shrinking block is slidably installed in the shrinking groove; and the shrinking spring is connected between the shrinking groove and the shrinking block.

[0022] In the above solution, by setting the separating slider as a rotatable and retractable structure, and under the action of the limiting plate, the separating slider can only automatically rotate and retract during the process of collectively pulling up and moving the cylindrical materials after they have been stacked and packaged. This ensures that when the cylindrical materials are stacked, the overall stability of the stacking structure is increased, the pressure of each layer on the lower layer is reduced, and the cylindrical materials can be taken off the stacking rack normally and smoothly without jamming between the cylinder and the fixing mechanism due to the separating slider.

[0023] Preferably, the connecting assembly includes a connecting rod and a driving block; the connecting rod is connected to the adjusting slider on the upper side of the bent plate; and the driving block is connected to the lowermost separating slider.

[0024] In the above scheme, the connecting rod slides under the pressure of the driving slider as the driving block follows the sliding block downwards. This causes the connecting rod to drive the adjusting slider to slide. Since the adjusting slider on the upper side of the bent plate is the outermost one that contacts the cylindrical material, when the adjusting slider slides, it will evenly stretch all the adjusting springs by a small distance to complete the pre-opening action between the adjusting sliders. This avoids the cylindrical material from being unable to smoothly enter between the two adjusting sliders due to the large diameter difference between the largest and smallest diameter materials produced. It ensures that the bottom cylindrical material can accurately enter the gap between each pair of adjusting sliders.

[0025] Preferably, the connecting rod is provided with a sliding wheel at its tail end; the driving block includes a downward pressing slope and a tightening rail.

[0026] In the above scheme, the downward pressing slope can press the connecting rod during the pressing process, thereby opening the adjusting spring. The opening distance can be controlled by adjusting the length of the downward pressing slope. The opening distance is controlled to a small distance to avoid the two cylinders falling into the gap between the two adjusting sliders due to the excessive opening distance. The tightening track is a horizontal track, so that after the sliding wheel is pressed away from the tightening slope, it enters the tightening track. The tightening distance can be freely adjusted under the action of the adjusting spring. Under the action of the adjusting spring, the connecting rod can automatically achieve the reset function, improving the automation level of the equipment.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. Compared to existing cylindrical palletizing devices, this invention, by setting the position of the adjusting plate to an automatically adjustable structure and making the adjusting spring and adjusting slider a detachable structure, can adapt to the packaging needs of cylindrical materials of various specifications and models, reducing the number of tooling required in the production process. The distance between the sliders can be adaptively adjusted under the pressure of the cylindrical material, accommodating cylindrical materials of different diameters and ensuring that the cylindrical materials placed on the bottom layer of the stacking rack are neatly shaped, thereby improving the stability of the overall stacking structure. This not only facilitates the organization and placement of tooling but also reduces production costs, allowing workers to complete the replacement and adjustment of the stacking rack in a short time, thus reducing the time spent changing tooling and improving work efficiency.

[0029] 2. This invention, by incorporating a separating slider, mitigates the impact of each layer of cylindrical material being lowered onto the already stacked layers during stacking. It also provides support to each layer and differentiates between them, ensuring the stability of the overall stacking structure. Furthermore, the rotatable and retractable separating slider does not obstruct subsequent packaging and handling, further improving the forming effect of the cylindrical material stacking. This effectively reduces problems such as poor strapping tightness and post-packaging collapse caused by poor stacking formation. This contributes to improved product quality, reduced customer complaints, and enhanced market competitiveness for enterprises.

[0030] 3. This invention, by inserting the curved portion of the adjusting plate between the adjusting sliders, achieves two objectives: firstly, to adjust the overall stacking structure dimensions to accommodate stacking different numbers of cylindrical materials; secondly, when cylindrical materials on the side press against the rotating portion of the adjusting plate, a torque is provided to the rotating portion, causing the curved portion to generate a flipping torque. Under the action of the flipping torque, the curved portion applies an upward pressure to the adjusting slider, thus ensuring the stability of both the adjusting slider and the curved portion, increasing friction, and preventing horizontal slippage. Furthermore, as the stacking weight increases, both the upward pressure and friction increase accordingly, maintaining the stability of the stacking structure and avoiding poor packaging results due to misshapen stacking, which would affect subsequent storage and transportation.

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0043] Please see Figures 1 to 9 This invention provides a combined packaging and palletizing equipment for cylindrical materials in a factory, the technical solution of which is as follows:

[0044] As a specific embodiment of the present invention, refer to Figure 1A combined packing and palletizing device for cylindrical materials in a factory includes a transport mechanism 1 and a gripping mechanism 2; it also includes a stacking frame 3, a fixing mechanism 4, and an adjusting mechanism 5; the stacking frame 3 is connected to the gripping mechanism 2; the fixing mechanism 4 is connected to the stacking frame 3; the adjusting mechanism 5 includes an adjusting hole 51 and an adjusting plate 52; the adjusting hole 51 is formed on the fixing mechanism 4; the adjusting plate 52 is connected to the fixing mechanism 4; the gripping mechanism 2 grips the cylindrical material to the stacking frame 3 and moves the cylindrical material... As the material slides downwards, the fixing mechanism 4 on the stacking rack 3 receives the downward-sliding cylindrical material and slowly moves it to the position of the adjusting mechanism 5. The adjusting hole 51 slides open under the pressure of the cylindrical material and then contracts to press the cylindrical material. The adjusting plate 52 is pressed and limited by the pressure of the outermost cylindrical material to limit the adjusting hole 51. When the second to last layer of cylindrical material is stacked, the fixing mechanism 4 separates the second to last layer of cylindrical material from the bottom layer of cylindrical material and provides some upward support force to the cylindrical material above the bottom layer.

[0045] As a specific embodiment of the present invention, refer to Figure 2 and Figure 3 The fixing mechanism 4 includes a fixing plate 41, a separation groove 42, a separation slider 43, a separation spring 44, and a connecting assembly 45; the separation groove 42 is formed on the inner wall of the fixing plate 41; a plurality of separation sliders 43 are slidably installed in the separation groove 42; the separation springs 44 are installed at intervals with the separation sliders 43; the connecting assembly 45 is connected between the separation sliders 43 and the adjusting mechanism 5. Separating sliders 43 are installed on the side wall of the fixed plate 41. Multiple separating sliders 43 are used. To ensure good support, the number of separating sliders 43 can be set to half the total number of stacked layers plus one. This allows the cylindrical material in the lower half of the stack to receive lateral support, preventing the lower structure from collapsing. The angle between the separating sliders 43 and the side wall of the fixed plate 41 is the same for each layer. When each layer of cylindrical material is lowered, the outermost cylindrical material will contact the side wall of the fixed plate 41 when it reaches the bottom position. At this time, the separating sliders 43 of the bottom layer will contact the outermost cylindrical material. This allows the cylindrical material to be clearly layered under the action of the separating sliders 43 during stacking. Furthermore, due to the action of the separating springs 44, the lowering of the cylindrical material is buffered, preventing impact on the bottom cylindrical material and causing collapse. Each layer can also receive some upward support under the elastic force of the separating springs 44, thus providing good support for each layer of cylindrical material.

[0046] As a specific embodiment of the present invention, refer to Figure 3The fixing plate 41 includes a base plate 411 and a support plate 412; the base plate 411 is connected to the stacking rack 3; the support plate 412 is connected to the base plate 411, and the included angle between the base plate 411 and the support plate 412 is 120 degrees. Since cylindrical materials are typically stacked into a hexagonal structure to ensure stability and reduce space occupation during stacking, and the interior angle of the hexagonal structure is 120 degrees, fixing the base plate 411 and the support plate 412 into a 120-degree structure provides good support for the stacked cylindrical materials, allowing them to be stacked in shape. This ensures that the outer ring of cylindrical materials can make tangential contact with the support plate 412, so that each cylindrical material in the outer ring receives support force, thereby ensuring the stability of the stacking structure.

[0047] As a specific embodiment of the present invention, refer to Figure 3 and Figure 4The adjusting hole 51 includes an adjusting groove 511, adjusting sliders 512, and adjusting springs 513. The adjusting grooves 511 are symmetrically arranged on both sides of the base plate 411. Multiple adjusting sliders 512 are slidably installed in the adjusting grooves 511. The adjusting springs 513 are installed at intervals with the adjusting sliders 512. The adjusting hole 51 is designed to automatically adjust its size, allowing cylindrical materials of different diameters to be placed. The distance between two adjusting sliders 512 can be adjusted by the elasticity of the adjusting springs 513. After the cylindrical material is placed between two adjusting sliders 512, the elasticity of the adjusting springs 513 clamps the cylindrical material, ensuring that the cylindrical material does not shake and increasing the stability of the bottom stack. This ensures that the material can be stacked and formed, and can accommodate cylindrical materials of different diameters. The upper part of the adjusting slider 512 is symmetrically provided with a fitting arc surface 5121, and the top ends of the fitting arc surfaces 5121 on the left and right sides of the upper part are tangent to each other, thereby ensuring that the top end is a pointed structure, thus ensuring that each cylindrical material can make tangential contact, thereby ensuring the compactness of the overall stacking structure and improving the packaging effect; the fitting arc surface 5121 is made of rubber, and when clamping the cylindrical material, the center of the arc of the fitting arc surface 5121 is set off-center from the center of the cylindrical material cross-section. The rubber-coated curved surface 5121 further enhances the stability of the bottom cylindrical material after clamping and fixing. The rubber material deforms to a certain extent under clamping force, maintaining its contact with the cylindrical material. It also increases friction without causing wear on the cylindrical material surface, thus preventing radial sliding under clamping force. Since the radius of curvature of the curved surface 5121 is greater than the radius of the cylindrical material, to ensure increased contact area, the center of the curved surface 5121 is offset from the center of the cylindrical material's cross-section when clamping. This results in better fixing of each bottom cylindrical material, improving stability. The adjusting spring 513 has threaded seats 5131 at both ends, and the elastic modulus of the adjusting spring 513 first decreases and then increases along the axial direction (i.e., the elastic modulus is large at both ends and small in the middle). This increases the resistance of the adjusting spring 513 to deformation after the cylindrical material is pressed downwards and spreads open the two adjusting sliders 512, resulting in the maximum clamping force on the cylindrical material when it is pressed down to be tangent to the base plate 411. The adjusting sliders 512 have threaded holes 5122 on both sides that mate with the threaded seats 5131. The adjusting spring 513 and the adjusting sliders 512 are designed as detachable structures, allowing the number of adjusting sliders 512 and adjusting springs 513 to be adjusted according to actual stacking requirements. This design enables quick changes in the work site without frequent tooling changes, thus adapting to different quantities and specifications of cylindrical materials.

[0048] As a specific embodiment of the present invention, refer to Figure 7 The adjusting plate 52 includes an adjusting plate body 521 and an adjusting support leg 522; the adjusting plate body 521 includes a rotating part 5211 and a bending part 5212; the adjusting support leg 522 is connected to the stacking rack 3; the rotating part 5211 is connected to the adjusting support leg 522; the bending part 5212 can be freely engaged with the adjusting slider 512. When the cylindrical material on the side presses against the rotating part 5211, it provides a torque to the rotating part 5211, thereby causing the bent plate part 5212 to generate a flipping torque. Under the action of the flipping torque, the bent plate part 5212 will apply an upward pressure to the adjusting slider 512, so that both the adjusting slider 512 and the bent plate part 5212 can remain stable, increasing the friction and preventing horizontal sliding. As the stacking weight increases, the upward pressure and friction will increase accordingly, thus maintaining the stability of the stacking structure. Furthermore, the bent plate part 5212 can be freely engaged between the two adjusting sliders 512, making the disassembly and assembly of the structure more flexible and suitable for cylindrical materials of various quantities and specifications, further improving its practicality.

[0049] As a specific embodiment of the present invention, refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The separating slider 43 includes a limiting plate 431, a separating rotating block 432, a shrinking block 433, and a shrinking spring 434. The limiting plate 431 is slidably installed in the separating groove 42. The separating rotating block 432 is rotatably installed on the limiting plate 431, and a shrinking groove 4321 is provided on the separating rotating block 432. The shrinking block 433 is slidably installed in the shrinking groove 4321, and the surface of the shrinking block 433 that contacts the cylindrical material is set as an arc surface. The shrinking spring 434 is connected between the shrinking groove 4321 and the shrinking block 433. The elastic modulus of the shrinking spring 434 is set to be small enough so that the shrinking block 433 can shrink when it is squeezed with the cylindrical material without affecting the packaged cylindrical material. By setting the separating slider 43 as a rotatable and retractable structure, and under the action of the limiting plate 431, the separating slider 432 can only automatically rotate and retract during the process of the cylindrical materials being pulled up and moved after stacking and packaging. This ensures that when the cylindrical materials are stacked, the overall stability of the stacking structure is increased, the pressure of each layer on the lower layer is reduced, and the cylindrical materials can be taken off normally and smoothly from the stacking rack 3 after packaging, without jamming between the cylinder and the fixing mechanism 4 due to the separating slider 432.

[0050] As a specific embodiment of the present invention, refer to Figure 8 and Figure 9The connecting assembly 45 includes a connecting rod 451 and a driving block 452; the connecting rod 451 is connected to the adjusting slider 512 on the upper side of the bent plate portion 5212; the driving block 452 is connected to the lowermost separating slider 43. As the drive block 452 follows the sliding of the separating slider 43, the connecting rod 451 slides under the pressure of the drive slider, thereby causing the connecting rod 451 to drive the adjusting slider 512 to slide. Since the adjusting slider 512 on the upper side of the bent plate 5212 is the outermost one that contacts the cylindrical material, when the adjusting slider 512 slides, it will evenly stretch all the adjusting springs 513 by a small distance to complete the pre-opening action between the adjusting sliders 512. Since the adjusting springs 513 are designed with a large elastic modulus at both ends and a small elastic modulus in the middle, it ensures that when multiple adjusting springs 513 are opened, the middle part of the adjusting springs 513 is more easily stretched, so that the multiple adjusting springs 513 are stretched more evenly. This avoids the cylindrical material from not being able to smoothly enter between the two adjusting sliders 512 due to the large diameter difference between the largest and smallest diameter materials produced. It ensures that the bottom cylindrical material can accurately enter the gap between each pair of adjusting sliders 512. The connecting rod 451 is provided with a sliding wheel 4511 at its tail; the driving block 452 is provided with a pressing track 4521 at its lower part; a tightening track 4522 is provided above the pressing track 4521; the entire driving block 452 is provided with a detachable structure, and the included angle between the pressing track 4521 and the tightening track 4522 can be adjusted according to the diameter of the cylindrical material, so as to ensure that the specifications of the driving block 452 can be adjusted in time even for cylindrical materials with large diameter differences. During the downward pressing process, the inclined plane can press the connecting rod 451, thereby opening the adjusting spring 513. The opening distance can be controlled by adjusting the length of the inclined plane. By controlling the opening distance to a smaller range, it is possible to prevent the two cylinders from falling into the gap between the two adjusting sliders 512 due to excessive opening distance. The tightening track 4522 is a horizontal track, so that after the sliding wheel 4511 is pressed off the inclined plane, it enters the tightening track 4522. The tightening distance can be freely adjusted under the elastic force of the adjusting spring 513. Under the action of the adjusting spring 513, the connecting rod 451 can automatically achieve the reset function, improving the automation level of the equipment.

[0051] Workflow: The gripping mechanism 2 lowers the cylindrical material. When the bottom layer of cylindrical material is placed, the cylindrical material comes into contact with the separating slider 43. The separating slider 43 moves downward under the pressure of the cylindrical material. The driving block 452 follows the separating slider 43 to slide and squeeze the connecting rod 451. The connecting rod 451 drives the adjusting slider 512 to slide and pre-open. The cylindrical material continues to be pressed down, so that a single cylindrical material enters between the two adjusting sliders 512. At this time, the adjusting slider 512 clamps the cylindrical material under the action of the adjusting spring 513, and fixes the bottom layer of cylindrical material. The stacking of cylindrical materials continues. At this time, the adjusting plate 52, the separating slider 43, and the fixing plate 41 support the upper layer of cylindrical material.

[0052] Specifically, firstly, based on the number and diameter of the cylindrical materials to be stacked, the number of separating sliders 43 on the fixing mechanism 4 and the number of adjusting sliders 512 on the adjusting mechanism 5 are disassembled and adjusted. Simultaneously, the bent portion 5212 of the adjusting plate 52 is attached to the underside of the adjusting slider 512. The transport mechanism 1 transports the cylindrical materials to below the gripping mechanism 2. The gripping mechanism 2 grips the cylindrical materials to the stacking rack 3 position. The gripping mechanism 2 lowers the cylindrical materials. When placing the bottom layer of cylindrical materials, during the downward movement of the cylindrical materials, the outermost cylindrical materials exert downward pressure on the separating slider 43. At this time, the separating spring 44 is stretched, and the separating slider 43 slides down, driving the drive block. 452 slides down, pressing down the sliding wheel 4511 at the tail of the connecting rod 451 on the lower track 4521. This causes the adjusting slider 512 to slide under the thrust of the connecting rod 451, and multiple adjusting springs 513 are stretched evenly. As a result, multiple adjusting sliders 512 complete the pre-opening action. The cylindrical material continues to be pressed down, causing a single cylindrical material to enter between two adjusting sliders 512. Through the compression between the contact arc surface 5121 and the cylindrical material, the single cylindrical material completely expands the two adjusting sliders 512. The cylindrical material is then clamped and fixed by the elastic force of the contact arc surface 5121 and the adjusting springs 513. At this time, the sliding wheel 4511 enters the tightening state. Horizontal sliding occurs in track 4522 to ensure the tightening process is not affected; cylindrical materials continue to be stacked upwards. When the cylindrical materials on the side press against the rotating part 5211, they provide a torque to the rotating part 5211, thereby causing the bent plate part 5212 to generate a flipping torque. Under the action of the flipping torque, the bent plate part 5212 will exert an upward pressure on the adjusting slider 512, thus ensuring that both the adjusting slider 512 and the bent plate part 5212 remain stable, increasing friction and preventing horizontal sliding. As the stacking weight increases, the upward pressure and friction will also increase, thereby maintaining the stability of the stacking structure; and the cylindrical materials in each layer of stacking... The cylindrical material is separated by multiple separating sliders 43, preventing stacking and misshapen layers. As the separating sliders 43 slide down with the cylindrical material, they stretch the separating springs 44, reducing the impact on the lower structure during stacking and ensuring the stability of the overall stacking structure. After the overall stacking is completed, the cylindrical material is packaged with strapping. When the cylindrical material needs to be transported after packaging, it is lifted upwards. At this time, the separating rotating block 432 rotates automatically on the limiting plate 431. The shrinking block 433 is squeezed and shrinks into the separating rotating block 432, thus separating from the packaged cylindrical material and allowing it to be transported away smoothly.
