Description

Technical Field

[0001] The invention relates to the technical field of palletizing equipment, and in particular to a tire palletizing device. Background Art

[0002] After the tires are produced, they need to be palletized for the first time and then transported to the warehouse. After arriving at the warehouse, they need to be transported and re-palletized using palletizing equipment. During this process, the mobile mechanism of the palletizing equipment will move the clamping mechanism to the top of the tire and lower it to insert it into the tire. Then, the clamping plates on the outside of the clamping mechanism will hold the palletized tires. Then, the mobile mechanism will lift the tires through the clamping mechanism and move them to the predetermined position. In this way, the palletizing device can effectively palletize tires of different batches together, thereby reducing the footprint of the tires. When the above method is used for transportation and stacking, when the tires are stacked together, the weight of the upper tires will exert continuous downward pressure on the lower tires due to gravity, especially the tires on the bottom layer will be under the greatest pressure. Even if a clamp is used to clamp the inner side of the tire during transportation and sufficient friction is generated by applying an upward force to prevent the tire from sliding down, in theory, this friction can offset the gravity of the tire, but this cannot completely eliminate the interaction force between the upper and lower tires. Due to the transfer of force, each upper tire will exert a vertical downward force on the tire directly below it. This force comes directly from the weight of the upper tire, that is, the upper tire will still exert additional pressure on the lower tire, causing the tire on the bottom layer to be easily deformed and fall off. This pressure will not only affect the shape and structural integrity of the tire, but may also cause safety risks. Summary of the invention

[0003] In order to overcome the disadvantage that when tires are stacked, the weight of the upper tires will exert continuous pressure on the lower tires, which may cause the bottom tire to deform and fall off even if the clamps clamp the inner side, affecting the structural integrity and causing safety risks, the present invention provides a tire stacking device.

[0004] The technical solution is as follows: a tire stacking device comprises a connecting plate, a linkage assembly and a clamping plate; the connecting plate is connected to a linkage assembly; the linkage assembly is connected to a number of clamping plates; the connecting plate is connected to an external mobile device; it also comprises an electric push rod, a lifting rod, a sliding ring, a rotating plate, a torsion spring, a limit block, a lower pressure block and an upper push block; the connecting plate is fixedly connected to at least two electric push rods; the telescopic parts of all electric push rods are commonly fixedly connected to the lifting rod; the linkage assembly is connected to at least four sliding rings; each sliding ring is rotatably connected to at least four rotating plates; each rotating plate is commonly fixedly connected to a corresponding sliding ring with a torsion spring; each sliding ring is fixedly connected to at least four limit blocks; the lifting rod is fixedly connected to at least four lower pressure blocks distributed up and down; the lifting rod is fixedly connected to at least four upper push blocks distributed up and down; each upper push block is located below the corresponding lower pressure block; the middle part of each sliding ring is located between the lower pressure block and the upper push block.

[0006] Optionally, the upper portion of the limit block is inclined.

[0007] Optionally, the distance between the sliding ring and the adjacent push-up blocks increases gradually from top to bottom.

[0008] Optionally, the upper portion of the lifting rod is made of rubber material.

[0009] Optionally, fixed ropes are also included; each rotating plate is fixedly connected to the sliding ring by a plurality of fixed ropes.

[0010] Optionally, it also includes a slider and a pull rope; each clamp plate is slidably connected to at least four sliders; each slider is fixedly connected to a sliding ring at the same height by two pull ropes.

[0011] Optionally, the outer side of the slider is made of rubber.

[0012] Optionally, the pull rope is a steel wire rope.

[0013] Optionally, rotating wheels are also included; two rotating wheels are rotatably connected to the upper part of each clamping plate.

[0014] Compared with the prior art, the present invention has the following advantages: When the splint drives the tires to rise, the supporting effect of the rotating plate will disperse the downward pressure of each tire, help the bottom tire share the pressure, reduce the burden on the tire on the bottom layer, and avoid the situation where the weight of the upper tire will exert continuous pressure on the lower tire, affecting the structural integrity and causing safety risks.

[0015] The rotating plate at the top drives the tires in contact with it to rise in turn, ensuring that each tire is independent and non-contacting, which can completely eliminate pressure transmission and reduce the risk of deformation and potential damage to the tire at the bottom.

[0016] When the rotating plate pushes the tire to rise, the sliding ring will pull the drawstring to rise, so that the drawstring pulls the slider to rise. At this time, the rotating plate, the slider and the tire will rise synchronously, so that the clamping plate can be unfolded first to make the slider contact with the tire, reducing the preparation time.

[0020] Example 1 A tire stacking device, such as Figure 1-Figure 4 As shown, it includes a connecting plate 1, a linkage component and a clamping plate 5; the connecting plate 1 is connected to the linkage component; the linkage component is connected to four clamping plates 5; the connecting plate 1 is connected to the external mobile device; It also includes an electric push rod 6, a lifting rod 7, a sliding ring 8, a rotating plate 9, a torsion spring 10, a limit block 11, a lower pressing block 12 and an upper pushing block 13; the connecting plate 1 is fixedly connected to two electric push rods 6; the telescopic parts of all electric push rods 6 are fixedly connected to the lifting rod 7; the linkage assembly is connected to four sliding rings 8; each sliding ring 8 is rotatably connected to four rotating plates 9; each rotating plate 9 is fixedly connected to a torsion spring 10 with the corresponding sliding ring 8, and the rotating plate 9 is pushed to expand by the rebound of the torsion spring 10 state; each sliding ring 8 is fixedly connected with four limit blocks 11, through which the limit blocks 11 squeeze the rotating plate 9 to reset the rotating plate 9; the lifting rod 7 is fixedly connected with four upper and lower pressure blocks 12 distributed vertically, through which the rotating plate 9 is squeezed to descend; the lifting rod 7 is fixedly connected with four upper push blocks 13 distributed vertically, through which the rotating plate 9 is pushed up; each upper push block 13 is located below the corresponding lower push block 12; the middle part of each sliding ring 8 is located between the lower pressure block 12 and the upper push block 13.

[0021] The linkage assembly includes a pneumatic push rod 2, a lifting column 3 and a connecting block 4; four pneumatic push rods 2 are fixedly connected to the connecting plate 1; each telescopic part of all pneumatic push rods 2 is fixedly connected to a lifting column 3; the lifting column 3 is rotatably connected to a plurality of connecting blocks 4 in a ring array, all connecting blocks 4 are evenly distributed in a plurality of layers on the lifting column 3, and the connecting blocks 4 of two adjacent layers are aligned up and down; all connecting blocks 4 in the same column are rotatably connected to a clamping plate 5; the lifting rod 7 is located in the lifting column 3; the lifting column 3 is slidably connected to the sliding ring 8; the lifting column 3 is provided with a plurality of sliding openings 3001, and the sliding ring 8 slides up and down in the sliding openings 3001; the pneumatic push rod 2 is connected to an external power supply.

[0022] The upper portion of the limit block 11 is inclined, so as to facilitate the guide of the rotating plate 9 to descend into the limit block 11 .

[0023] From top to bottom, the distance between the sliding ring 8 and the adjacent push-up block 13 increases gradually, so that the upper and lower rotating plates 9 are driven to rise successively through the push-up block 13, so that the tires no longer contact each other.

[0024] The upper part of the lifting rod 7 is made of rubber material, which is soft and elastic, and can better adapt to the internal shape of the tire, reducing hard contact and potential damage to the inner wall of the tire.

[0025] It also includes fixing ropes 111 ; each rotating plate 9 and the sliding ring 8 are fixedly connected with a plurality of fixing ropes 111 .

[0026] The specific working steps are: Before work, the connecting plate 1 is connected to the external mobile device by bolts, and the connecting plate 1 is driven to move by the external mobile device.

[0027] When handling and stacking are required, the connecting plate 1, the pneumatic push rod 2, the lifting column 3, the connecting block 4 and the clamping plate 5 are moved to the top of the multiple tires to be stacked by the external mobile device, and then the external mobile device drives the connecting plate 1, the pneumatic push rod 2, the lifting column 3, the connecting block 4 and the clamping plate 5 to descend, so that the lifting column 3, the connecting block 4 and the clamping plate 5 are inserted into the multiple tires, and then the pneumatic push rod 2 drives the lifting column 3 to rise, at this time the lifting column 3 drives the connecting block 4 and the clamping plate 5 to rise together, and the clamping plate 5 is blocked by the connecting plate 1 during the rising process. As the lifting column 3 drives the connecting block 4 and the clamping plate 5 to continue to rise, the connecting block 4 will go around the lifting column 3. , and the connection point of the clamping plate 5 is rotated. Specifically, since one end of the connecting block 4 connected to the clamping plate 5 cannot rise, when the lifting column 3 drives the other end of the connecting block 4 to rise, the connecting block 4 will push all the clamping plates 5 to move outward and unfold. The unfolded clamping plates 5 will squeeze the inner sides of multiple tires to clamp the multiple tires, and then the external mobile device drives the connecting plate 1 to rise and move, and the multiple stacked tires are driven to rise and move through the clamping plate 5. After moving to the specified position, the multiple tires can be put down, and the external mobile device drives the tire to descend, and then the clamping plate 5 is controlled to be retracted to the original position, and prepare for the next handling work. In the above manner, one The tires with a small number of pallets are stacked together twice to reduce the floor space; when the lifting column 3 descends and drives the lifting rod 7, the sliding ring 8, the rotating plate 9, the torsion spring 10, the limit block 11, the lower pressure block 12 and the upper push block 13 to be inserted into multiple tires, the rotating plate 9 will be located in the middle position of the tire in the vertical direction, and the electric push rod 6 first drives the lifting rod 7 and the upper push block 13 to rise, so that the upper push block 13 rises and pushes the sliding ring 8 and the rotating plate 9 to rise together. When the rotating plate 9 rises away from the limit block 11 and loses its limit, the torsion spring 10 in a compressed state will rebound and drive the rotating plate 9 to rotate, so that the rotating plate 9 is unfolded, and the unfolded rotating plate 9 The rotating plate 9 will be inserted into the hollow tire, and as the rotating plate 9 continues to rise, the rotating plate 9 will contact the inner upper edge of the tire. At this time, the rotating plate 9 will support the tire in contact with it, and then the rotating plate 9 stops rising, and the clamping plate 5 will also unfold and contact multiple tires, and then start to carry and stack multiple tires. When the clamping plate 5 drives the tire to rise, the supporting effect of the rotating plate 9 will disperse the downward pressure of each tire, help the bottom tire share the pressure, reduce the burden of the bottom tire, and avoid the weight of the upper tire will exert continuous pressure on the lower tire, affecting the structural integrity and causing safety risks.After the handling and stacking work is completed, the electric push rod 6 drives the pressing block 12 to descend and squeeze the sliding ring 8 through the lifting rod 7, so that the sliding ring 8 drives the rotating plate 9 to descend and return to its original position. During the descent and resetting process of the rotating plate 9, the rotating plate 9 will contact the limit block 11, and the limit block 11 remains stationary relative to the descent of the rotating plate 9. As the rotating plate 9 continues to descend, the limit block 11 pushes the rotating plate 9 to rotate in the direction close to the lifting column 3, and the torsion spring 10 is compressed again to reset the rotating plate 9. The way in which the rotating plate 9 is reset during the descent process can avoid the obstruction of the upper edge of the inner side of the tire when the rotating plate 9 is directly reset; it should be noted that when the pneumatic push rod 2 drives the lifting column 3 to rise, the electric push rod 6 will drive the lifting rod 7 to rise synchronously to avoid mutual collision. ;

[0028] Even in the supported state, if the tires still maintain contact with each other, the weight of the upper tire will still exert pressure on the lower tire, causing the lowest tire to deform. Therefore, the initial position of the upper push block 13 located at the top is closer to the sliding ring 8, so that the upper push block 13 first pushes the sliding ring 8 to rise, allowing the rotating plate 9 to unfold. As the upper push block 13 continues to move, the rotating plate 9 will drive the tire to rise. At this time, the upper tire will not contact the lower tire, and then the rotating plate 9 at the lower tire position will unfold and drive the tire to rise without contacting the next tire. This process is repeated, so that the stacked tires no longer contact each other, and then the handling and stacking work can be carried out. The rotating plate 9 located at the top drives the tires in contact with it to rise in turn, ensuring that each tire is independent and non-contacting, which can completely eliminate pressure transmission and reduce the risk of deformation and potential damage to the tire at the bottom.

[0029] When the rotating plate 9 is in the unfolded state, the fixing rope 111 will be in a taut state, sharing the downward pressure brought to the torsion spring 10 by the tire through the rotating plate 9, thereby preventing the torsion spring 10 from fatigue damage.

[0030] Example 2 On the basis of Example 1, Figure 1 , Figure 3 and Figure 5 As shown, it also includes a slider 101 and a pull rope 102; each clamp plate 5 is slidably connected to four sliders 101; each slider 101 is fixedly connected to the sliding ring 8 at the same height by two pull ropes 102, and the slider 101 is pulled up by the pull rope 102.

[0031] The outer side of the slider 101 is made of rubber material, which can increase the friction between the slider and the tire.

[0032] The pull rope 102 is a steel wire rope.

[0033] It also includes a rotating wheel 201; each upper portion of each clamping plate 5 is rotatably connected to two rotating wheels 201, and the rotating wheels 201 are used to prevent the clamping plate 5 from directly rubbing against the connecting plate 1.

[0034] The specific working steps are: Since the rotating plates 9 need to drive the tires to rise in sequence, the clamping plates 5 need to wait until all the rotating plates 9 rise before they can be unfolded, which will affect the overall work efficiency. Therefore, when the rotating plates 9 are unfolded, the clamping plates 5 will also be unfolded synchronously. When the clamping plates 5 are unfolded, the clamping plates 5 will drive the slider 101 and the pull rope 102 to move, and the pull rope 102 will be in a taut state, and the slider 101 will also contact and clamp a corresponding tire, and then the upper push block 13 which is closer will first push the corresponding sliding ring 8 to drive the rotating plates 9 to rise, so that when the rotating plates 9 push the tire to rise, the sliding ring 8 will pull the pull rope 102 to rise, and the pull rope 102 will pull the slider 101 to rise. At this time, the rotating plates 9, the slider 101 and the tire will rise synchronously, so that the clamping plates 5 can be unfolded first to make the slider 101 contact with the tire, thereby reducing the preparation time.

[0035] When the splint 5 rises, it is blocked by the connecting plate 1 and slides and unfolds on the connecting plate 1. At this time, the splint 5 can roll on the connecting plate 1 through the rotating wheel 201 to avoid direct friction between the splint 5 and the connecting plate 1, thereby reducing mechanical wear, increasing service life, and reducing maintenance costs of the device.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
