Description

Technical Field

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

[0002] Tire vulcanization is one of the most important links in the tire manufacturing process. In the vulcanization process, the vulcanization bladder, as an important tool for tire manufacturing, is mainly used to load the inner cavity of the tire embryo to be vulcanized, and to shape and vulcanize the tire by introducing a heating medium (such as steam, hot water or nitrogen) in conjunction with a vulcanizer. Since the vulcanization process is mostly in a high-temperature environment, after long-term use, the vulcanization bladder will age and over-expand. Therefore, the vulcanization bladder needs to be replaced after a certain number of uses.

[0003] When the vulcanization bladder is in use, it is necessary to detachably set the vulcanization bladder on the central mechanism of the vulcanizer. The central mechanism is mainly used to control the extension and contraction of the bladder, shaping vulcanization and tire demolding. Specifically, the central mechanism includes a cylinder head, a central column vertically arranged on the cylinder head, and a limiting part detachably arranged on the central column. The vulcanization bladder is placed on the central column, and the vulcanization bladder is rotatably clamped on the cylinder head. The limiting part is used to limit the axial displacement of the vulcanization bladder.

[0004] At present, when replacing the curing bladder, it is necessary to first manually remove the curing bladder on the central mechanism and move it out of the curing machine by hoisting. Then, the curing bladder is placed on the central mechanism by hoisting again and manually fixed to the central mechanism. The whole process takes a long time and is inefficient. At the same time, the bladder is heavy, and there are safety risks in the process of manual removal and installation.

[0005] Therefore, the above problems need to be solved urgently. Summary of the invention

[0063] See also Figures 1 to 3 In the vulcanization process, the vulcanization bladder 200 is arranged on the central mechanism 100, wherein the central mechanism 100 includes a cylinder head 110, a central column 120 vertically arranged on the cylinder head 110, and a limit portion 1 detachably arranged on the central column 120. The vulcanization bladder 200 is sleeved on the central column 120, and the vulcanization bladder 200 is rotatably clamped on the cylinder head 110. The limit portion 1 is at the end away from the cylinder head 110 and is used to limit the axial displacement of the vulcanization bladder 200. The vulcanization bladder 200 includes a bladder body 210 and an upper clamping ring 220 and a lower clamping ring 230 respectively arranged at both ends of the bladder body 210, wherein the upper clamping ring 220 is fixed to the top of the bladder body 210 by bolts or clamping devices to ensure the sealing of the bladder during the vulcanization process, and the lower clamping ring 230 is detachably fixed to the central mechanism 100 of the vulcanizer to provide a stable support foundation for the bladder body 210 to prevent it from displacement or distortion under high pressure. In addition, a limit ring 121 is provided on the center column 120, and the limit ring 121 can abut against the inside of the upper clamping ring 220, so that the vulcanization bladder 200 can be kept in an extended state; when the vulcanization bladder 200 is replaced, it is necessary to manually remove or install the vulcanization bladder 200, and the whole process takes a long time and is inefficient. At the same time, the bladder is heavy, and there are safety risks in the process of manual removal and installation. For this reason, a vulcanization bladder replacement device is proposed in this embodiment to improve the replacement efficiency of the vulcanization bladder 200 and ensure the safety of the vulcanization bladder 200 during the replacement process.

[0064] Specifically, see Figures 4 to 8, the vulcanization capsule replacement device includes a driving part 2, a disassembly and assembly part 3, and a locking part 4. The driving part 2 has a driving end 21; the disassembly and assembly part 3 is arranged at the driving end 21 and is configured to remove the limiting part 1 from the central column 120 and be able to reinstall the limiting part 1 onto the central column 120; the locking part 4 is arranged at the driving end 21 and is configured to lock the vulcanization capsule; the driving part 2 is configured to drive the vulcanization capsule 200 to rotate in the first direction (such as clockwise) so that the vulcanization capsule 200 is in a position where it can be disengaged from the cylinder head 110, and is configured to drive the vulcanization capsule 200 to move axially along the central column 120 after the limiting part 1 is disengaged from the central column 120 to disengage from the central mechanism 100; the driving part 2 is further configured to sleave a new vulcanization capsule locked to the locking part onto the central column 120 and rotate in the second direction (such as counterclockwise) opposite to the first direction so that the new vulcanization capsule is clamped with the cylinder head 110. Among them, the driving part 2 is a six-axis manipulator in the prior art, and the end effector of the six-axis manipulator serves as the driving end 21, which can realize functions such as rotation, lifting, and translation.

[0065] It can be understood that with the cooperation of the driving part 2 and the disassembly and assembly part 3, the connection between the limiting part 1 and the central column 120 can be released, the vulcanization capsule 200 can be locked by the locking part 4, and under the action of the driving part 2, the old vulcanization capsule 200 can be removed, and the new vulcanization capsule 200 can be placed on the central column 120. Subsequently, under the action of the driving part 2, the limiting part 1 can be reinstalled onto the central column 120 to complete the replacement of the vulcanization capsule 200. The whole process does not require manual participation, effectively improving the replacement efficiency of the vulcanization capsule 200 and ensuring safety.

[0066] In this embodiment, a limiting groove 122 is provided on the outer peripheral wall of the central column 120; the limiting part 1 includes a limiting member 11, a blocking member 12, and a pin 13. The limiting member 11 is partially inserted into the limiting groove 122, and the limiting member 11 and the blocking member 12 can form a through space for passing through the central column 120; among them, one end of the blocking member 12 is rotatably connected to the limiting member 11, and the other end can be fixedly connected to the limiting member 11 through the pin 13. It can be understood that the limiting member 11 is partially inserted into the limiting groove 122, then the blocking member 12 is rotated so that the other end of the blocking member 12 can rotate to a position connected to the limiting member 11, and finally the blocking member 12 is fixed by the pin 13, thereby completing the installation of the limiting part 1. Among them, the limiting groove 122 is an annular groove, and the limiting member 11 can rotate circumferentially along the annular groove to adapt to different assembly positions, thereby improving the applicability of the replacement device.

[0067] Preferably, the limiting member 11 is a U-shaped limiting block. A limiting extension block 113 is provided on the inner side wall of the U-shaped limiting block. The limiting extension block 113 is slidably adapted to the limiting groove 122 to facilitate the installation of the limiting member 11 onto the central column 120. The two ends of the U-shaped limiting block are respectively defined as a first end 111 and a second end 112. The blocking member 12 is a cross bar. One end of the blocking member 12 is rotatably provided at the first end 111, and a positioning hole is provided at the other end. The second end 112 is provided in the positioning groove 1121. A pin hole is provided on the side of the U-shaped limiting block where the second end 112 is located. The pin hole communicates with the positioning groove 1121. After the blocking member 12 rotates, it can be located in the positioning groove 1121 to close the penetrating space. Then, the push pin 13 is moved so that the push pin 13 is inserted into the positioning hole.

[0068] In addition, the limiting portion 1 further includes a return spring. The return spring is sleeved outside the push pin 13 and is compressively arranged inside the limiting member 11, and can elastically deform when the push pin 13 moves away from the positioning hole, so as to have elastic potential energy for reinserting into the positioning hole.

[0069] Further, an ear is provided at one end of the blocking member 12 facing away from the push pin 13, and the ear extends outside the limiting member 11; wherein, the disassembly and assembly portion 3 includes a disassembly and assembly bracket 31, a disassembly and assembly member 32, and a pressing member 33. The disassembly and assembly bracket 31 is connected to the driving end 21; the disassembly and assembly member 32 is vertically arranged on the disassembly and assembly bracket 31, and a cutting surface 321 is provided at one end facing away from the disassembly and assembly bracket 31. The driving portion 2 is used to drive the disassembly and assembly member 32 to approach the push pin 13, so that the pin tail abuts against the cutting surface 321, thereby enabling the push pin 13 to slide along its axial direction and disengage from the blocking member 12; the pressing member 33 is vertically arranged on the disassembly and assembly bracket 31, and the pressing member 33 is used to press the ear downwards after the push pin 13 disengages from the blocking member 12 to open the penetrating space. It can be understood that when it is necessary to disassemble and assemble the connection between the limiting portion 1 and the central column 120, the driving portion 2 controls the disassembly and assembly bracket 31 to approach the limiting portion 1. At this time, the end of the disassembly and assembly member 32 is located between the pin tail of the push pin 13 and the limiting block. As the driving portion 2 continuously controls the disassembly and assembly bracket 31 to move, the pin tail can abut against the cutting surface 321. Since the thickness of the disassembly and assembly member 32 continuously increases, the push pin 13 can be pushed to move in a direction away from the ear, thereby being able to release the limit on the blocking member 12. At this time, the return spring is in a compressed state. As the driving portion 2 continuously controls the disassembly and assembly bracket 31 to move, the pressing member 33 can push the ear to rotate downwards, and relatively, the side facing away from the ear rotates upwards to open the penetrating space. The pressing member 33 is preferably strip-shaped.

[0070] Preferably, when the threading space is opened, the lug can abut against the limiting member 11 so that the blocking member 12 inclines towards the inner side of the threading space. When installing the limiting member 11, the disassembly and assembly bracket 31 can move upward under the action of the driving portion 2, so that the pressing member 33 can be separated from the lug. The blocking member 12 can rotate under the action of its own gravity and be located in the positioning groove 1121. And as the disassembly and assembly bracket 31 continues to move, the disassembly and assembly member 32 is separated from the nail tail. Under the action of the return spring, the pin 13 can be inserted into the positioning hole again.

[0071] Wherein, the disassembly and assembly member 32 includes two disassembly and assembly rods 322. Cutting surfaces 321 are arranged on one sides of the two disassembly and assembly rods 322 away from the disassembly and assembly bracket 31. The two disassembly and assembly rods 322 form a Y shape to form an avoidance groove 323 for avoiding the pin 13 between the two disassembly and assembly rods 322. During the movement of the disassembly and assembly member 32, the body of the pin 13 can enter the avoidance groove 323, and the cutting surfaces 321 on both sides can abut against the nail tail to push the pin 13 to move.

[0072] It should be noted that, in order to ensure that the nail tail can abut against the two cutting surfaces 321 simultaneously, a washer with a diameter larger than the nail tail can be sleeved on the pin 13.

[0073] In this embodiment, the disassembly and assembly portion 3 further includes a clamping mechanism 34. The clamping mechanism 34 is arranged on the disassembly and assembly bracket 31 and is used for clamping the limiting member 11. The driving portion 2 is further used for moving the limiting member 11 along the radial direction of the central column 120. It can be understood that after the blocking member 12 is opened, the entire limiting portion is still at the top of the vulcanization capsule 200. At this time, the clamping mechanism 34 can clamp the limiting member 11. Subsequently, under the action of the driving portion 2, it can drive the disassembly and assembly member 32 to move along the radial direction of the central column 120, so as to facilitate the subsequent separation of the vulcanization capsule 200 from the central column 120.

[0074] Exemplarily, the clamping mechanism 34 is an electric claw. The electric claw has two clamping ends. The two clamping ends are respectively on both sides of the limiting member 11, and the two clamping ends can move relatively to complete the clamping of the limiting member 11.

[0075] It should be noted that after the limiting member 11 is removed, the driving part 2 can place the limiting member 11 on the buffer rack so that after the vulcanization capsule 200 is replaced subsequently, the limiting member 11 can be installed on the central column 120 again. In this embodiment, the vulcanization capsule replacement device further includes a visual positioning part 5 and an attitude adjustment part 6. The visual positioning part 5 is arranged at the driving end 21 and is electrically connected to the driving part 2. The visual positioning part 5 is used to position the limiting member 11; the attitude adjustment part 6 is arranged at the driving end 21, and the attitude adjustment part 6 is used to adjust the attitude of the limiting member 11 so that the limiting member 11 is in a preset attitude. It can be understood that due to the vibration of the vulcanizer or in different replacement scenarios, the position of the limiting part 1 will be adjusted. Therefore, before disconnecting the connection between the limiting part 1 and the central column 120, the visual positioning part 5 is used to visually position the position of the limiting part 1. The visual positioning part 5 is preferably an industrial vision camera in the prior art. And the visual positioning part 5 can transmit the position information of the limiting part 1 to the driving part 2, and then under the action of the attitude adjustment part 6, the limiting part 1 is adjusted to the preset attitude, so as to facilitate the disassembly and assembly of the connection between the limiting part 1 and the central column 120 by the disassembly and assembly part 3. The preset attitude refers to the position that facilitates the disassembly and assembly of the limiting part 1 by the disassembly and assembly part 3.

[0076] Among them, the attitude adjustment mechanism is an adjustment cover, and the adjustment cover is adapted to the limiting member 11. Under the action of the driving part 2, the adjustment cover can be covered on the limiting member 11 to limit both sides of the limiting member 11, and then the driving part 2 drives the adjustment cover to rotate to the required position to complete the attitude adjustment of the limiting part 1.

[0077] In this embodiment, since the capsule body 210 of the vulcanization capsule 200 is made of flexible rubber and the upper clamping ring 220 and the lower clamping ring 230 are relatively heavy, in order to ensure the stability of the vulcanization capsule 200 during the replacement process, it is necessary to lock the upper clamping ring 220 and the lower clamping ring 230 simultaneously through the locking part 4.

[0078] Specifically, the locking part 4 includes a first locking mechanism 41 and a second locking mechanism 42. The first locking mechanism 41 is arranged at the driving end 21 and has a first locking end for locking the upper clamping ring 220; the second locking mechanism 42 is arranged at the driving end 21 and has a second locking end for locking the lower clamping ring 230, and the second locking end is below the first locking end. It can be understood that the first locking mechanism 41 can lock the upper clamping ring 220, and the second locking mechanism 42 can lock the lower clamping ring 230, so that the vulcanization capsule 200 can be kept vertically arranged during the handling process. The vertically arranged vulcanization capsule 200 can make its gravity evenly distributed along the axis, avoiding radial compression deformation caused by horizontal placement, so as to ensure the stability of the vulcanization capsule 200 during the handling process, and the handling device does not require manual participation during the handling process, thus improving the handling efficiency and safety performance.

[0079] Among them, the second locking mechanism 42 includes at least two locking arms 421 and at least two locking claws 422. The at least two locking arms 421 are respectively slidably arranged on the connecting part, and are evenly distributed around the vertical center line of the vulcanizing capsule 200 and can move radially synchronously to form a centering structure; the at least two locking claws 422 are arranged on the locking arms 421 in one-to-one correspondence, and the multiple locking claws 422 can cooperate with each other to form a second locking end. It can be understood that after the vulcanizing capsule 200 is assembled, it is set in a vertical state as a whole, that is, the axis of the vulcanizing capsule 200 is in the vertical direction. When the second locking mechanism 42 locks the lower clamping ring 230, the vulcanizing capsule 200 is placed between all the locking arms 421, and under the action of the centering structure formed by the multiple locking arms 421, the lower clamping ring 230 can be centered and locked and clamped. In addition, using a mechanical method to lock the lower clamping ring 230 can provide rigid support to further improve the stability of the vulcanizing capsule 200 during handling. Especially when handling heavy capsules, mechanical clamping provides stronger holding force.

[0080] It should be noted that a plurality of linear guide rails are arranged at the bottom of the connecting part. The plurality of linear guide rails are arranged in one-to-one correspondence with the plurality of locking arms 421, and the length direction of any linear guide rail is consistent with the radial direction of the vulcanizing capsule 200. The second locking mechanism 42 further includes an electric linear module, which is arranged on the connecting part and is used to drive the locking arm 421 to move along the linear guide rail. The first locking mechanism 41 is an electromagnetic adsorption structure, and the electromagnetic adsorption structure includes an electromagnetic suction ring, and the electromagnetic suction ring forms a first locking end and is coaxially arranged with the vertical center line of the vulcanizing capsule 200. It can be understood that using an electromagnetic adsorption structure to lock the upper clamping ring 220 does not require designing a dedicated clamping structure and adding an additional motor or the like as a power source, and the structure is simple. The electromagnetic adsorption structure can quickly and efficiently lock the upper clamping ring 220 to improve the handling efficiency.

[0081] Among them, the electromagnetic adsorption structure further includes a power supply module, and the power supply module can supply current to the electromagnetic suction ring and can further improve the applicability of the handling device by adjusting the current magnitude to adapt to upper clamping rings 220 of different weights.

[0082] Using electromagnetic adsorption locking and mechanical clamping locking together to lock the vulcanizing capsule 200 can take into account both stability and handling efficiency, and form redundant protection. Even if one party fails, the stability of the vulcanizing capsule 200 during handling can still be maintained temporarily, reducing the risk of accidental detachment.

[0083] In this embodiment, an annular groove is provided on the inner peripheral wall of the lower snap ring 230, and a plurality of openings are evenly spaced apart at the bottom of the annular groove; a plurality of protrusions 1110 are evenly spaced on the outer peripheral wall of the cylinder head 110, and the protrusions 1110 are adapted to the annular groove. The lower snap ring 230 has a locked state in which the protrusions 1110 and the openings are staggered, and an unlocked state in which the protrusions 1110 and the openings are aligned. The driving part 2 is used to drive the lower snap ring 230 to switch between the locked state and the unlocked state. It can be understood that when removing the vulcanization capsule 200, it is necessary to switch the lower snap ring 230 from the locked state to the unlocked state. After the second locking end locks the lower snap ring 230, under the action of the driving part 2, the lower snap ring 230 can be driven to rotate, so that the opening can be rotated to a position aligned with the protrusion 1110, and then the vulcanization capsule 200 can be lifted under the action of the driving part 2 to complete the removal of the vulcanization capsule 200 to be replaced. When replacing the new vulcanization capsule 200, the first locking end locks the upper snap ring 220, and the second locking end locks the lower snap ring 230. Under the action of the driving part 2, the new vulcanization capsule 200 can be moved above the central mechanism 100. Since the positions of the first locking end and the second locking end do not change during the movement, the attitude of the capsule body 210 does not change during the movement of the vulcanization capsule 200, thus ensuring the stability of the vulcanization capsule 200. When the driving part 2 places the vulcanization capsule 200 on the central mechanism 100, the protrusion 1110 is aligned with the opening, so that the top end of the central column 120 can sequentially pass through the lower snap ring 230, the capsule body 210 and the upper snap ring 220, and the protrusion 1110 can be located in the annular groove. Then the driving part 2 rotates the lower snap ring 230, so that the protrusion 1110 and the opening are staggered, that is, the driving part 2 can switch the lower snap ring 230 from the unlocked state to the locked state. Then, under the cooperation of the driving part 2 and the clamping mechanism 34, the limiting part 11 can be inserted into the limiting groove 122 to complete the replacement of the vulcanization capsule 200.

[0084] In this embodiment, the vulcanization capsule replacement device further includes a storage unit 7, a moving unit 8, and a plurality of temporary storage units 9. The storage unit 7 is used to store the new vulcanization capsule 200 to be replaced; the moving unit 8 reciprocates between the central mechanism 100 and the storage unit 7; the plurality of temporary storage units 9 are arranged at intervals on the moving unit 8, and the number of temporary storage units 9 is greater than the number of vulcanization capsules 200 to be replaced. Any one of the temporary storage units 9 is used to temporarily store the vulcanization capsule 200 to be replaced or the new vulcanization capsule 200. Among them, the driving unit 2 is arranged on the moving unit 8, and the driving unit 2 is used to transport the new vulcanization capsule 200 on the storage unit 7 to the temporary storage unit 9, and is also used to, when the moving unit 8 moves to the central mechanism 100, transport the vulcanization capsule 200 to be replaced on the central mechanism 100 to an idle temporary storage unit 9, and transport the new vulcanization capsule 200 on the temporary storage unit 9 to the central mechanism 100. Among them, the moving unit 8 is preferably an AGV vehicle.

[0085] It can be understood that when the vulcanization capsule 200 needs to be replaced, the moving unit 8 moves with the driving unit 2 to the position where the storage unit 7 is located. Under the action of the driving unit 2 and the locking unit 4, the new vulcanization capsule 200 can be placed on the temporary storage unit 9. Subsequently, the moving unit 8 carrying the new vulcanization capsule 200 moves to the vulcanizer. Under the combined action of the driving unit 2, the contact unit, and the locking unit 4, the vulcanization capsule 200 to be replaced can be removed from the central mechanism 100 and placed on an idle temporary storage unit 9. Subsequently, under the combined action of the driving unit 2, the contact unit, and the locking unit 4, the vulcanization capsule 200 can be installed on the central mechanism 100. The whole process does not require manual participation, which can improve safety and replacement efficiency.

[0086] Among them, the storage unit 7 includes a storage table 71 and a plurality of storage mechanisms 72. The plurality of storage mechanisms 72 are arranged on any one of the storage mechanisms 72 for vertically fixing the new vulcanization capsule 200, and the number of new vulcanization capsules 200 stored is less than the number of storage mechanisms 72. It can be understood that after the vulcanization capsule 200 is replaced, the transportation unit can transport the vulcanization capsule 200 to be replaced to the storage unit 7. Under the combined action of the driving unit 2, the contact unit, and the locking unit 4, the vulcanization capsule 200 to be replaced can be placed on an idle storage mechanism 72 for recycling. It should be noted that the specific structures of the central mechanism 100, the temporary storage unit 9, and the storage mechanism 72 are the same. Such a setting can ensure that the vulcanization capsule 200 can be maintained in an extended state at different workstations, thereby ensuring the stability of the vulcanization capsule 200.

[0087] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
