Description

Technical Field

[0001] This invention belongs to the technical field of V-belt production equipment, and relates to an automatic V-belt assembly and disassembly device. Background Technology

[0002] Vulcanization is a crucial step in the production of rubber V-belts, requiring the use of a ring-shaped vulcanizing mold. The vulcanizing mold typically consists of multiple interlocking rings (i.e., mold material rings, including an intermediate layer and a top layer) and a mold base stacked together. Each V-belt is fitted onto one mold material ring, and then another mold material ring is placed on top, and so on, layer by layer, to form a complete vulcanizing mold. After assembly, the mold is fed into vulcanizing equipment for vulcanization. Once vulcanization is complete, the mold is disassembled layer by layer, and the vulcanized V-belts are removed.

[0003] Currently, the above-mentioned disassembly and assembly operations mostly rely on manual labor, which is not only labor-intensive and costly, but also inefficient and cannot meet the needs of large-scale production.

[0004] Chinese patent CN110355914A (publication date 2021-04-20) discloses a fully automatic film-coating machine, which includes an assembly module and a disassembly module, capable of automatically installing and removing rubber V-belts. The disassembly device in this patent uses a pry gripper, inserting a pry bar into the gap between the rubber V-belt and the vulcanizing mold, and removing the rubber V-belt through relative movement. However, this prying method has limitations in peeling off V-belts that may stick together after vulcanization, and its integration of the disassembly and assembly actions is not high. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic V-belt disassembly and assembly device, which features a compact structure, high degree of automation, and more reliable disassembly and assembly performance.

[0006] To solve the above-mentioned technical problems, the objective of this invention is achieved through the following technical solution: An automatic V-belt installation and removal device, comprising: A flipping mechanism includes a flippable material rack for carrying a mold containing a vulcanized V-belt. The material rack flips between a vertical feeding position and a longitudinal unloading position. The material rack is equipped with a peeling component that separates and transfers the mold base and mold material ring from the mold layer by layer. The assembly / disassembly mechanism includes a rotatable turntable with multiple internal support clamps arranged circumferentially on the turntable. These internal support clamps are rotatably mounted on the turntable and circulate between a receiving station, a tape removal station, and a tape assembly station. The receiving station receives the mold material ring transferred from the stripping component; The strip removal station is equipped with a strip removal assembly on one side, which includes a strip removal blade. The strip removal blade cooperates with the rotating inner support clamp to remove the vulcanized V-belt from the mold material ring. The strip loading station is used to load the V-belt to be vulcanized onto the mold material ring.

[0007] As a further improvement of the present invention, the front bottom of the material rack is hinged to the flipping base via a flipping shaft. The flipping mechanism also includes a flipping drive device, one end of which is hinged to the flipping base and the other end of which is hinged to the material rack, driving the material rack to flip between vertical and longitudinal directions.

[0008] As a further improvement of the present invention, the peeling assembly includes a peeling swing arm and peeling claws disposed on the peeling swing arm, and a swing shaft driven by a swing drive device is disposed through the flipping shaft, and the peeling swing arm is mounted on both ends of the swing shaft and swings with the swing shaft.

[0009] As a further improvement of the present invention, the peeling claw is laterally movable on the peeling swing arm, and the peeling claw has a first clamping surface and a second clamping surface. The first clamping surface is used to clamp the outer peripheral surface of the mold base, and the second clamping surface is used to clamp the inner peripheral surface of the mold material ring.

[0010] As a further improvement of the present invention, the material rack is provided with clamping components on both sides. The clamping components include clamping blocks and clamping drive devices for driving the clamping blocks. When peeling off the current mold material ring, the clamping blocks are pressed onto the next mold material ring.

[0011] As a further improvement of the present invention, a pushing assembly is provided on the rear side of the material rack. The pushing assembly includes a pushing plate and a pushing drive device for driving the pushing plate. The pushing assembly pushes the mold forward so that the mold material ring at the foremost end is always in the peeling position.

[0012] As a further improvement of the present invention, the turntable is provided with a stripping seat in the middle, and a movable stripping tool holder is provided on the side of the stripping seat facing the stripping station, and the stripping tool is rotatably mounted on the stripping tool holder.

[0013] As a further improvement of the present invention, a tape removal driving device is provided on one side of the tape removal station, the inner support clamp is rotatably mounted on the turntable via the clamp shaft, the clamp shaft is provided with a driven transmission component, the output end of the tape removal driving device is provided with an active transmission component, the tape removal driving device can be driven by the lifting device to move vertically, and when it moves to the top, the active transmission component and the driven transmission component engage and transmit power.

[0014] As a further improvement of the present invention, the turntable is also provided with a material unloading station, which is equipped with a material unloading device for stacking the mold material rings containing the vulcanizing V-belts onto the mold base in sequence to form a complete mold.

[0015] The present invention also provides an automatic method for attaching and detaching V-belts, the method comprising the following steps: (1) Feeding: Place the vulcanized mold on the material rack, flip the material rack so that the axis of the mold changes from vertical to longitudinal; (2) Mold separation: The mold base is separated first by the peeling component, and then the mold material ring is peeled off layer by layer. The separated mold material ring is then transferred to the inner support fixture at the receiving station. (3) Strip removal: Rotate the inner support clamp from the receiving station to the strip removal station, and use the strip removal tool to remove the vulcanized V-belt from the mold material ring. (4) Belt loading: Rotate the inner support clamp from the belt unloading station to the belt loading station, and put the V-belt to be vulcanized onto the mold material ring; (5) Unloading: Rotate the inner support fixture from the belt loading station to the unloading station, and stack the mold base and mold material ring in sequence to form a complete mold containing the vulcanized triangular belt.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention provides an automatic assembly and disassembly method for V-belts, adding a flipping feeding mechanism to make process connections smoother. Specifically, this invention drives the material rack to flip between the vertical feeding station and the longitudinal picking station through the flipping mechanism, changing the mold's axial direction from vertical to longitudinal, providing a suitable working posture for subsequent layer-by-layer peeling. In addition, the flipping shaft and the swing shaft of the peeling arm adopt a coaxial through-type design, with a compact layout and no interference between their movements.

[0017] 2. The peeling claws of this invention have a first clamping surface and a second clamping surface, which can respectively clamp the outer peripheral surface of the mold base and the inner peripheral surface of the mold material ring. First, the mold base is peeled off using an external clamping method, and then the mold material rings are peeled off layer by layer using an internal supporting method. Simultaneously, the clamping component clamps the next mold material ring while peeling off the current mold material ring to prevent displacement; the pushing component pushes the mold forward, ensuring that the foremost mold material ring is always in the peeling position. These three components work together to ensure the stability and accuracy of layer-by-layer separation.

[0018] 3. This invention employs a strip removal scheme at the strip removal station that combines a strip removal tool with a rotating inner support clamp. After the strip removal tool extends into the gap between the vulcanized V-belt and the mold material ring, the inner support clamp drives the mold material ring to rotate, and the strip removal tool scrapes off the vulcanized V-belt along the circumferential direction. Compared to the axial pulling method, this circumferential scraping method has a stronger peeling ability for V-belts that may stick together after vulcanization.

[0019] 4. This invention features multiple internal support clamps arranged circumferentially on the turntable. These clamps rotate cyclically between the receiving station, the stripping station, and the loading station, integrating the separation, stripping, and loading processes into one unit. Each station can operate in parallel, resulting in a compact overall cycle time. The stripping drive device employs a liftable, separable meshing structure, providing rotational power to the internal support clamps only at the stripping station. This eliminates the need for independent drive devices at each station, simplifying the structure and facilitating control. The unloading station ensures continuous stripping and stacking, with the stripping sequence matching the final stacking sequence. The operational logic is clear, the machine boasts a high degree of automation, requires minimal manual intervention, and is suitable for the automation transformation of large-scale V-belt production.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-7 : like Figure 1As shown in the figure, the automatic V-belt disassembly and assembly device provided in this embodiment mainly consists of two parts: a flipping mechanism and a disassembly and assembly mechanism.

[0022] Flipping mechanism like Figure 2 and Figure 3 As shown, the flipping mechanism includes a flipping base 14 and a material rack 1. The front bottom of the material rack 1 is hinged to the flipping base 14 via a flipping shaft 13. Its initial state is vertical, used to receive the vulcanized and upright mold 2 placed by a lifting device or robot. A flipping drive device 15 is provided between the flipping base 14 and the material rack 1. In this embodiment, it is a flipping cylinder, whose cylinder body is hinged to the flipping base 14 and whose piston rod is hinged to the material rack 1. When the flipping cylinder extends, it pushes the material rack 1 to flip backward around the flipping shaft 13, so that the material rack 1 and the mold 2 on it switch from the vertical loading position to the longitudinal unloading position. When switching from the loading position to the unloading position, the mold 2 is slightly tilted backward, and its axial direction changes from vertical to longitudinal, which facilitates subsequent layer-by-layer peeling.

[0023] The peeling assembly 3 is mounted on the material rack 1 and mainly includes peeling swing arms 16 and peeling claws 17. The flipping shaft 13 is a hollow shaft with a swing drive device 18 running through it. In this embodiment, it is a swing shaft 19 driven by a swing motor. There are two peeling swing arms 16, which are fixedly installed at both ends of the swing shaft 19 and can swing within a certain angle with the swing shaft 19.

[0024] like Figure 4 As shown, the peeling claw 17 is laterally slidable on the inner side of the peeling swing arm 16 via a slide rail, and is driven by the peeling cylinder to move laterally (i.e., radially towards the mold 2). The peeling claw 17 has two functional surfaces: a first clamping surface 20 located on the outer end face and a second clamping surface 21 located on the inner side face. The first clamping surface 20 is arc-shaped and is used to externally clamp the outer peripheral surface of the mold base 4; the second clamping surface 21 is also arc-shaped and is used to internally clamp the inner peripheral surface of the mold material ring 5.

[0025] To achieve layer-by-layer peeling, clamping assemblies are also provided on both sides of the material rack 1, including a clamping drive device 23, which in this embodiment is a clamping block 22 driven by a clamping cylinder. When peeling the current mold material ring 5, the clamping block 22 presses radially against the next mold material ring 5 to prevent it from being pulled out along with it. Figure 4 As shown, a pushing assembly is provided on the rear side of the material rack 1, including a pushing drive device 25, which in this embodiment is a pushing plate 24 driven by a pushing motor. Each time a component is peeled off, the pushing plate 24 pushes the remaining mold 2 forward one station along the axial direction, so that the foremost component is always within the working range of the peeling claw 17.

[0026] Disassembly and assembly mechanism like Figure 5As shown, the assembly / disassembly mechanism includes a circumferentially rotatable turntable 6, with four stations evenly arranged circumferentially on the turntable 6: a material receiving station 8, a strip unloading station 9, a strip loading station 10, and a material unloading station 33. Each station on the turntable 6 is equipped with an internal support clamp 7, which is rotatably mounted on the turntable 6 via a clamp shaft 29. The internal support clamp 7 has radially expandable support blocks for internally tightening the mold material ring 5.

[0027] like Figure 6 As shown, the strip removal station 9 is equipped with a strip removal assembly 11. Specifically, a strip removal seat 26 is provided in the middle of the turntable 6, and a movable strip removal tool holder 27 is provided on the side of the strip removal seat 26 facing the strip removal station 9. The strip removal tool holder 27 is driven by a cylinder assembly and can be moved from the standby position to the working position. When the strip removal tool holder 27 moves to the working position, the strip removal tool 12 is inserted into the gap between the vulcanized V-belt and the mold material ring 5. The strip removal tool 12 is rotatably mounted on the strip removal tool holder 27 to adapt to the outer circumference contour of the mold material ring 5.

[0028] A tape removal drive device 28 is provided on one side of the tape removal station 9. The inner support clamp 7 is rotatably mounted on the turntable 6 via a clamp shaft 29. A driven transmission component 30 is provided on the clamp shaft 29. An active transmission component 31 is provided at the output end of the tape removal drive device 28. The tape removal drive device 28 can be driven to move vertically by a lifting device 32. When it moves to the top, the active transmission component 31 engages with the driven transmission component 30. In this embodiment, a tape removal motor is provided on one side of the tape removal station 9. The tape removal motor is mounted on a lifting cylinder and can slide vertically. A drive gear is mounted on the shaft end of the tape removal motor, and a matching clamp gear is mounted on the bottom of the clamp shaft 29. When the inner support clamp 7 carries the mold material ring 5 to the tape removal station 9, the lifting cylinder lifts the tape removal motor, causing the drive gear to engage with the clamp gear, thereby driving the inner support clamp 7 to rotate.

[0029] A belt-picking rod 35 is also hinged to the belt-removing seat 26. The belt-picking rod 35 is connected to the belt-picking cylinder 37 via a connecting rod 36 and can swing under the drive of the cylinder. A belt-hanging frame 38 is provided on the outside of the belt-removing station 9.

[0030] The working process of this embodiment is as follows: (1) Feeding: After vulcanization is completed, the mold 2 is hoisted onto the material rack 1 in the vertical feeding position. The tilting cylinder drives the material rack 1 to tilt backward to the longitudinal material picking position, and the mold 2 leans against the push plate 24 in a slightly backward state.

[0031] (2) Separation of mold 2: First, peel off mold base 4: peeling arm 16 swings to the working position, peeling claw 17 moves from the outside to the inside, and hugs the outer periphery of mold base 4 through the first clamping surface 20. Then peeling arm 16 swings outward to pull out mold base 4 and transfer it to the inner support clamp 7 of unloading station 33.

[0032] Then, the mold material rings 5 ​​are peeled off layer by layer: the pushing assembly pushes the mold 2 forward axially, so that the foremost mold material ring 5 reaches the peeling position. The peeling claw 17 is initially located inside the mold 2, and moves outward to support the inner circumferential surface of the mold material ring 5 through the second clamping surface 21. The clamping assembly clamps the next material ring, and the peeling swing arm 16 swings outward to separate the current mold material ring 5 from the mold 2 and transfer it to the inner support clamp 7 of the receiving station 8. This process is repeated until all mold material rings 5 ​​are separated.

[0033] (3) Strip Removal: The turntable 6 rotates, moving the mold material ring 5 containing the V-belt to be stripped from the receiving station 8 to the strip removal station 9. The strip removal tool holder 27 moves, inserting the strip removal tool 12 into the gap between the vulcanized V-belt and the mold material ring 5. The lifting cylinder lifts the strip removal motor, causing the drive gear to mesh with the clamp gear, driving the inner support clamp 7 and the mold material ring 5 to rotate. The stationary strip removal tool 12, rotating with the material ring, scrapes off the entire circle of the vulcanized V-belt. Subsequently, the strip picking rod 35 swings, picking up the scraped V-belt onto the hanging frame 38.

[0034] (4) Loading the belt: The turntable 6 continues to rotate, and the mold material ring 5, from the belt removal station 9, is moved to the belt loading station 10. The operator or the automated device loads the new V-belt to be vulcanized onto the mold material ring 5.

[0035] (5) Unloading: The turntable 6 rotates to move the mold material ring 5 with the new V-belt from the belt loading station 10 to the unloading station 33. The unloading device 34 (such as a robot) first removes the mold base 4 from the inner support clamp 7 and places it in the stacking area, and then removes each mold material ring 5 in sequence and stacks them on the mold base 4 to form a complete set of vulcanizing mold 2.

[0036] By continuously rotating the turntable 6 and repeating the above process, the continuous automatic assembly and disassembly of the V-belt mold 2 can be achieved.

[0037] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
