DETAILED DESCRIPTION

[0023] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should fall within the protection scope of the present application.

[0024] Please refer to Figures 1 to 4 According to the embodiments of the present application, an unloading device is provided, which comprises a tray 1, a mounting seat 2, a first embracing member 3 and a second embracing member 4. The tray 1 is located on the mounting seat 2 and is rotatably arranged relative to the mounting seat 2. The tray 1 has an unloading station and an initial station. The mounting seat 2 is movably arranged and is used to drive the tray 1 to approach or move away from a shaping drum. The first embracing member 3 and the second embracing member 4 are arranged on the tray 1 in a spaced manner and are oppositely arranged. The first embracing member 3 and the second embracing member 4 are used to embrace or avoid a tire blank. When the unloading device is unloading, the tray 1 is located at the unloading station so that the bearing surface 101 of the tray 1 is parallel to the end surface of the shaping drum. When the unloading device completes unloading, the tray 1 is switched from the unloading station to the initial station so that the bearing surface 101 of the tray 1 is upwardly arranged and the tire blank is placed on the bearing surface 101 of the tray 1.

[0025] It can be seen that the tire unloading device has the following advantages. The tire unloading device is provided with the tray 1, the mounting seat 2, the first holding member 3 and the second holding member 4, and the tire unloading process is optimized. When the tire unloading device starts to work, the tray 1 rotates relative to the mounting seat 2, so that the tray 1 is located at the tire unloading station, and the bearing surface 101 of the tray 1 is parallel to the end surface of the shaping drum. Then, the mounting seat 2 drives the tray 1 to move towards the shaping drum, so that the tray 1 approaches the tire blank, and the tire blank is stably clamped by the first holding member 3 and the second holding member 4. In this way, when the mounting seat 2 moves along the axis direction of the shaping drum, the tire blank can be smoothly transferred from the shaping drum to the tray 1. After the unloading is completed, the tray 1 rotates relative to the mounting seat 2 again, so that the bearing surface 101 faces upwards, thereby stably placing the tire blank on the tray. By making the bearing surface 101 of the tray 1 parallel to the end surface of the shaping drum, the tire blank can be stably transferred from the shaping drum to the tray, the risk of deformation caused by uneven local stress is reduced, and unnecessary mechanical interference is reduced. At the same time, the tray 1 is quickly switched between the tire unloading station and the initial station, the efficiency of the entire tire unloading process is improved, and the operation time is shortened. The movable mounting seat 2 enables the tray 1 to flexibly approach or move away from the shaping drum, thereby conveniently unloading the tire blank. In addition, the design of the first holding member 3 and the second holding member 4 ensures the stability of the tire blank during unloading, and prevents the tire blank from being displaced or damaged during the transfer process. During unloading, the tray 1 can be restored to the initial position, so that the tire blank is placed flat on the bearing surface 101, thereby avoiding the deformation problem caused by the excessive weight of the tire blank, and improving the safety and quality during transportation. The tire unloading device not only realizes efficient tire unloading operation, but also greatly improves the safety and stability of the operation. At the same time, the flexible movement mechanism improves the overall production efficiency and automation level, effectively solves the technical problem that the tire blank is easily deformed when the existing technology adopts the crane to hang the cloth pocket to unload the giant tire blank from the shaping drum.

[0026] Further, the area of the bearing surface 101 of the tray 1 is greater than the area of the tire blank.

[0027] Further, the bearing surface 101 of the tray 1, the first holding member 3 and the second holding member 4 form a clamping space, so that the tire blank is stably fixed in the clamping space by the first holding member 3 and the second holding member 4 during the tire unloading process. By clamping the first holding member 3 and the second holding member 4, the tire blank will not be displaced during the tire unloading process, thereby improving the safety and stability of the operation. The stable clamping space can reduce the misoperation during the tire unloading process, improve the work efficiency and reduce the labor cost. Effective clamping can prevent the tire blank from being damaged during the operation, and prolong the service life of the product.

[0028] Further, the first and second embracing members 3 and 4 are rotatably arranged on the tray 1 and protrude from the bearing surface 101 of the tray 1. The first and second embracing members 3 and 4 are arranged correspondingly and can move relative to each other. By adjusting the mutual approach or distance of the two embracing members, the size of the clamping space can be adjusted.

[0029] Optionally, after the tire blank is processed on the shaping drum, the tire unloading device without carrying the tire blank is moved to the vicinity of the shaping drum, and then the tray 1 is rotated relative to the mounting seat 2 from the initial position to the tire unloading position, so that the bearing surface 101 of the tray is parallelly aligned with the end surface of the shaping drum. After the position adjustment is completed, the mounting seat 2 drives the tray 1 to move along the axis direction of the shaping drum towards the tire blank, at this time, the first and second embracing members 3 and 4 are in an open state to avoid the tire blank, when the bearing surface 101 of the tray 1 contacts the side surface of the tire blank, the first and second embracing members 3 and 4 are respectively rotated relative to the tray 1, and then the first and second embracing members 3 and 4 embrace the tire blank, so as to fix the tire blank on the bearing surface 101 of the tray 1. Finally, the mounting seat 2 is moved away from the shaping drum along the axis direction of the shaping drum, so as to unload the tire blank from the shaping drum. When the tire blank is separated from the shaping drum, the tray 1 drives the tire blank to rotate, so that the tray 1 returns to the initial position, and then the tire blank is placed horizontally on the bearing surface 101 of the tray 1 (i.e. the axis of the tire blank is perpendicular to the horizontal direction at this time). Thus, the tire blank can be conveniently transported to the next process by the tire unloading device. Further, the deformation problem caused by the excessive weight of the tire blank is avoided during transportation, and the safety and quality during transportation are improved.

[0030] During the unloading process, since the contact area between the bearing surface 101 of the tray 1 and the tire blank is large, the stability of the tire blank during the transfer process is ensured, and the tire blank is prevented from being displaced or damaged during the unloading process. It can be seen that the entire tire unloading process is accurately controlled by the automatic control system, ensuring the accuracy of the tire unloading action, greatly improving the production efficiency and the safety of the operation.

[0031] Specifically, as shown in FIG. 1, the tire unloading device comprises a mounting seat 2 and a tray 1 arranged on the mounting seat 2. Figures 1 to 4As shown, the tire unloading device further comprises a supporting member 5 arranged on the tray 1 and protruding from the bearing surface 101 of the tray 1, and the supporting member 5 is arranged separately from the first clamping member 3 and the second clamping member 4, and the supporting member 5 is located on the side of the tray 1 close to the shaping drum; and the supporting member 5 is used for supporting the tire blank. With such a structure, the tire blank is provided with an additional support point by arranging the supporting member 5, which facilitates supporting the tire blank during tire unloading, thereby reducing the risk of deformation of the tire blank due to uneven local stress during transfer. The design of the supporting member 5 ensures uniform pressure distribution of the tire blank during transfer, preventing displacement or damage caused by excessive local stress, further improving the stability of the operation.

[0032] Further, the supporting surface 50 of the supporting member 5 is provided with an arc-shaped groove matched with the tread of the tire blank, which ensures that the tread can closely fit the arc-shaped groove when the tire blank is placed on the supporting member 5, increases the contact area, and enables the pressure borne by the tire blank during unloading to be more evenly distributed, avoiding deformation or damage caused by excessive local stress. In addition, it can also enhance the stability of the tire blank on the supporting member, preventing displacement or sliding of the tire blank during transfer.

[0033] Optionally, the supporting member 5 is a supporting block.

[0034] Further, as shown, Figures 1 to 4 the cross section of the tray 1 is circular, and the bearing surface 101 of the tray 1 is provided with an avoiding hole 100 extending along the axis direction of the tray 1; wherein, when the tire unloading device unloads the tire, the tray 1 is driven by the mounting seat 2 to approach the tire blank on the shaping drum, so that the shaping drum is arranged on the avoiding hole 100. With such a structure, by arranging the avoiding hole 100, physical collision between the tray 1 and the shaping drum during tire unloading is avoided, ensuring the safety and smoothness of the operation. And by arranging the avoiding hole 100, it ensures that the tire blank can be smoothly transferred from the shaping drum to the tray 1, reduces the risk caused by mechanical interference, and improves the safety of the operation.

[0035] Optionally, the cross-sectional area of the avoiding hole 100 is larger than the cross-sectional area of the shaping drum.

[0036] Optionally, the edge of the bearing surface 101 of the tray 1 is higher than the axis of the bearing surface 101 of the tray 1. The bearing surface 101 of the tray 1 has a slight negative curvature. The design of the edge of the bearing surface 101 being higher than the axis helps to prevent the tire blank from sliding or shifting on the tray, especially during the tire unloading process or during transportation, ensuring the stable placement of the tire blank. The slight negative curvature enables the weight of the tire blank to be more evenly distributed on the bearing surface 101, reducing the risk of excessive local stress and avoiding deformation or damage caused by concentrated pressure. The slight negative curvature of the bearing surface helps to guide the tire blank to naturally center, ensuring that the position of the tire blank on the tray is more accurate, facilitating the operation of subsequent processes.

[0037] Specifically, as shown in Figures 1 to 4 , the tire unloading device further comprises a telescopic assembly 6 telescopically arranged on the mounting seat 2 along a first preset direction, and the telescopic assembly 6 is hinged to the tray 1 to drive the tray 1 to rotate relative to the mounting seat 2 by extending or contracting the telescopic assembly 6. The telescoping direction of the telescopic assembly 6 forms a first preset angle with the horizontal direction, and the first preset angle is greater than 0° and less than 90°. With such a structural arrangement, the design of the telescopic assembly 6 enables the tray 1 to be flexibly switched between the tire unloading station and the initial station, and the angle of the tray 1 can be accurately controlled by extending or contracting the telescopic assembly 6, ensuring that the bearing surface can accurately align with the forming drum to achieve smooth tire blank transfer. At the same time, the telescoping direction of the telescopic assembly 6 forms a certain angle with the horizontal direction, avoiding mechanical interference that may be caused by vertical or horizontal movement, and improving the safety of the entire tire unloading process.

[0038] Specifically, as shown in Figures 1 to 4 , the telescopic assembly 6 comprises a first telescopic rod 61 and a second telescopic rod 62, and the first telescopic rod 61 and the second telescopic rod 62 are arranged in a length direction of the mounting seat 2. The first telescopic rod 61 and the second telescopic rod 62 are both hinged to the tray 1 to drive the tray 1 to rotate relative to the mounting seat 2 by synchronously extending and contracting the first telescopic rod 61 and the second telescopic rod 62. With such a structural arrangement, the first telescopic rod 61 and the second telescopic rod 62 are arranged in the length direction of the mounting seat 2, ensuring that the tray 1 is uniformly stressed during the turning process, and avoiding deformation or damage caused by excessive local stress. Moreover, the synchronous action of the first telescopic rod 61 and the second telescopic rod 62 enables the tray 1 to be smoothly switched between the tire unloading station and the initial station, reducing the risk of mechanical interference caused by uneven stress and improving the safety of the entire tire unloading process.

[0039] The length direction of the mounting seat 2 is the direction indicated by arrow A in Figure 1 .

[0040] Specifically, as shown in Figures 1 to 4As shown, the tire unloading device further comprises a moving rod 7 movably arranged on the mounting seat 2 along a second preset direction, the moving rod 7 extending along the length direction of the mounting seat 2; one end of the telescopic assembly 6 away from the tray 1 is adjustably connected with the moving rod 7, so as to adjust the distance between the moving rod 7 and the tray 1 by adjusting the position of the telescopic assembly 6 relative to the moving rod 7; wherein when the moving rod 7 moves along the second preset direction, the moving rod 7 drives the tray 1 to rotate relative to the mounting seat 2 through the telescopic assembly 6; the moving direction of the moving rod 7 forms a second preset included angle with the horizontal direction, the second preset included angle is greater than 0° and less than 90°.

[0041] With such a structural arrangement, by arranging the moving rod 7, the tray 1 can be further ensured to rotate to the tire unloading position. Through the movement of the moving rod 7 and the cooperation of the telescopic assembly 6, the position of the tray 1 relative to the mounting seat 2 can be further accurately adjusted, ensuring that the bearing surface 101 of the tray 1 can accurately align with the forming drum during tire unloading, achieving smooth tire blank transfer. The moving direction of the moving rod 7 forms a certain included angle with the horizontal direction, avoiding mechanical interference that may be caused by vertical or horizontal movement, and improving the safety of the entire tire unloading process. The rapid movement of the moving rod 7 and the synchronous action of the telescopic assembly enable the tray 1 to complete position switching in a short time, shortening the operation time and improving the efficiency of the overall tire unloading process. At the same time, the inclined moving direction of the moving rod 7 ensures that the tray 1 is uniformly stressed during rotation, avoiding deformation or damage caused by uneven local stress, and protecting the quality of the tire blank. In addition, the combined design of the moving rod 7 and the telescopic assembly 6 not only applies to standard tire unloading operations, but also can be adjusted according to actual needs to adapt to different working conditions, enhancing the versatility and flexibility of the device. Moreover, since the moving rod 7 and the telescopic assembly 6 share the load, the wear of individual components is reduced, prolonging the service life of the entire device.

[0042] Further, the first telescopic rod 61 and the second telescopic rod 62 are respectively located on both sides of the moving rod 7, and the first telescopic rod 61 and the second telescopic rod 62 are adjustably connected with the moving rod 7, so as to adjust the distance between the two ends of the moving rod 7 and the tray 1 by adjusting the positions of the first telescopic rod 61 and the second telescopic rod 62 relative to the moving rod 7. With such a structural arrangement, the initial distance can be adjusted according to actual conditions to adapt to different installation requirements and size of the tray.

[0043] Optionally, the extension and retraction of the first telescopic rod 61 and the second telescopic rod 62 are controlled by a hydraulic or pneumatic system, ensuring the smoothness and accuracy of the operation. The pressure of the hydraulic or pneumatic system can be adjusted according to actual needs to adapt to the unloading operation of tires of different weights and sizes. During the extension and retraction of the first telescopic rod 61 and the second telescopic rod 62, the tray 1 can remain in a horizontal state, which is crucial to ensure the smooth unloading of the tire. In this way, the tire unloading device not only improves the convenience of operation, but also enhances the safety of operation.

[0044] Optionally, when switching the tray 1 from the initial position to the tire unloading position, the moving rod 7 first moves in a second preset direction towards the tray 1, thereby causing the first telescopic rod 61 and the second telescopic rod 62 to rotate relative to the moving rod 7, thereby realizing the rotation of the tray 1 relative to the mounting seat 2. When the moving rod 7 moves to the limit position, the first telescopic rod 61 and the second telescopic rod 62 are synchronously extended, finally adjusting the tray 1 to the tire unloading position.

[0045] Specifically, as shown in Figures 1 to 4 the tire unloading device further comprises a driving structure 8 mounted on the mounting seat 2, the driving structure 8 is drivingly connected with the moving rod 7, and the driving structure 8 is used to drive the moving rod 7 to move in the second preset direction.

[0046] Specifically, as shown in Figures 1 to 4 the tire unloading device further comprises a first support frame 9 and a second support frame 10, the first support frame 9 and the second support frame 10 are arranged on the mounting seat 2 in a length direction of the mounting seat 2; the first support frame 9 and the second support frame 10 are both provided with a guide hole 11 extending in the second preset direction; both ends of the moving rod 7 are respectively arranged in the two guide holes 11, and the moving rod 7 moves along the extension direction of the guide hole 11. With such a structure, the first support frame 9 and the second support frame 10 can provide stable support for the moving rod 7, enhance the structural rigidity of the entire device, and reduce the risk of deformation or damage caused by uneven force on the moving rod. The guide hole 11 extending in the preset direction on the first support frame 9 and the second support frame 10 can ensure that the moving rod 7 moves smoothly and accurately along the second preset direction during movement, avoiding deviation or jamming and improving the accuracy of the entire operation.

[0047] Optionally, the first telescopic rod 61 is located on the side of the first support frame 9 away from the second support frame 10, and the second telescopic rod 62 is located on the side of the second support frame 10 away from the first support frame 9.

[0048] Specifically, as shown in Figures 1 to 4As shown, the tire unloading device further comprises a fixed frame 12, the fixed frame 12 is installed on the mounting seat 2, and the fixed frame 12 protrudes from the mounting seat 2; the tray 1 is rotatably arranged at the top end of the fixed frame 12; the fixed frame 12 is arranged along the width direction of the mounting seat 2 and is located on the side of the mounting seat 2 close to the shaping drum. By adopting such a structural arrangement, by arranging the fixed frame 12, the rotating space of the tray 1 is effectively increased, thereby avoiding interference between the edge of the tray 1 and the mounting seat 2, so that the tray 1 can be smoothly adjusted to the tire unloading position. And by arranging the fixed frame 12, a stable support point can be provided for the tray 1, especially when the tray 1 is performing a turnover action, the stability and accuracy of its movement are ensured.

[0049] The width direction of the mounting seat 2 is Figure 2 The direction indicated by arrow B in the figure.

[0050] Further, the top end of the fixed frame 12 is provided with a mounting groove 120 extending along the length direction of the mounting seat 2. The tire unloading device further comprises a connecting piece 14 fixedly connected with the tray 1, and the connecting piece 14 is rotatably arranged in the mounting groove 120, so as to drive the tray 1 to rotate relative to the fixed frame 12 through the rotation of the connecting piece 14.

[0051] Further, the tire unloading device further comprises a rotating shaft 15 arranged in the mounting groove 120, and the axis of the rotating shaft 15 extends along the length direction of the mounting seat 2. The connecting piece 14 is rotatably sleeved on the rotating shaft 15.

[0052] Specifically, as Figures 1 to 4 shown, the mounting seat 2 is provided with an opening groove 20 close to the shaping drum; at least part of the supporting piece 5 is located in the opening groove 20 when the tray 1 is in the tire unloading position. By adopting such a structural arrangement, by arranging the opening groove 20 in the mounting seat 2, a clearance can be provided for the supporting piece 5, so as to ensure that at least part of the supporting piece 5 can smoothly enter the opening groove 20 when the tray is turned over to the tire unloading position, avoiding mechanical interference between the supporting piece 5 and the mounting seat 2, improving the safety and smoothness of the operation.
