Description

Technical Field

[0001] The invention relates to the technical field of tire manufacturing, and in particular to a car tire vulcanization switching device. Background Art

[0002] The main process flow of tire manufacturing includes raw material preparation, mixing, semi-component preparation, molding, vulcanization, inspection and final product delivery. Among them, the molding process is particularly important, which combines the calendered or extruded semi-components according to certain process requirements through the bonding or pressing of equipment to form an unvulcanized tire, that is, a green tire.

[0003] Green tires need to be stored for a short time before vulcanization. The efficiency and safety of green tire storage directly affect the smoothness of the entire production process and product quality. At present, green tire storage generally adopts automatic storage and retrieval to improve production efficiency and optimize production processes. There are two main ways to store green tires: truss + flat warehouse and stacker three-dimensional warehouse storage. Regardless of the storage method, the green tire needs a reliable carrying device, as well as the green tire from the green tire forming station to the storage location for storage process, or transferred to the aging furnace to enter the green tire aging process.

[0004] The green tire storage device commonly used in the industry is mainly a metal pot-shaped device; however, this device has the following significant defects:

[0005] 1. High processing cost: The device can only ensure its arc by stamping, and the steel plate needs to be stamped into the shape of a pot. This process is not only complicated but also costly.

[0006] 2. Easy to deform and damage: The pot-shaped component needs to be welded to the base, but the welding process is prone to deformation and damage, affecting the service life of the device.

[0007] 3. Inconvenient transportation: The device is easily deformed during transportation, resulting in damage, which affects the shape condition of the green tire for storage.

[0008] 4. Green tire adhesion: Since the green tire itself is relatively soft and has high viscosity, it is easy to adhere to the surface of the pot-shaped device, making it difficult to grab when leaving the warehouse, and may even damage the green tire.

[0009] At present, there is a lack of automated auxiliary tools for transferring the green tire from the green tire forming station to the storage location. Usually, the green tire is placed in a metal pot-shaped device on a trolley for transfer. However, when placing the green tire on the trolley or taking it out from the trolley, it is basically carried by hand wearing non-stick gloves. However, when carrying the green tire manually, it is easy to be unbalanced when holding the green tire with both hands, which makes the green tire easily deformed.

[0010] In view of the defects of the above-mentioned raw tire storage device, it is necessary to improve the design of an automatic or semi-automatic device for receiving / placing raw tires and a device for transporting / transferring raw tires, so that the two devices can be combined to realize the automatic handling process of multiple receiving / placing steps of the raw tires from the forming station to the storage location, avoid deformation of the raw tires during the transportation process, and achieve higher efficiency, safety and high reliability of raw tire transportation compared with the existing technology.

[0011] In summary, the applicant has found that the prior art has at least the following technical problems:

[0012] The green tire placement and transfer equipment in the existing green tire transfer process steps still has the problems of low automation and low reliability. Summary of the invention

[0045] The beneficial effects of the present invention are as follows:

[0046] In the tire vulcanization process, the application of the tire vulcanization transfer device can produce the following significant effects on the entire production process of green tire generation, removal, transportation, grabbing, tire vulcanization / temporary storage:

[0047] (1) Improve the transfer efficiency of green tires, thereby improving production efficiency;

[0048] The tire vulcanization transfer device uses the transport cylinder, lifting cylinder and lifting platform on the cart in an automated way, in conjunction with the green tire lowering equipment (truss gripper or EMS), to achieve mechanized green tire docking and green tire transfer between workstations, thus achieving efficient transfer of green tires from the production line to the vulcanizer. The traditional manual transfer method is not only time-consuming, but also prone to damage caused by improper operation. The introduction of this device helps to reduce the transfer time, thereby shortening the production cycle and improving overall production efficiency. The design and movement coordination of the lifting cylinder and lifting platform ensure the smooth and efficient transfer of green tires during the transfer process, improve the automation of the device, and avoid deformation caused by manual handling of green tires.

[0049] (2) Improve the safety of green tire transportation;

[0050] The protective frame installed on the second placement station can effectively prevent the green tire from being damaged due to external collision or accidental falling during transportation. It can fully guarantee the integrity of the green tire and reduce the risk of occasional operator errors. Compared with traditional manual handling, the device has a high degree of automation, which reduces the frequency of contact between workers and production line machinery and equipment, thereby reducing potential safety hazards.

[0051] (3) Reduce the deformation of the green tire during transportation;

[0052] During the production process, the integrity and shape quality of the green tire are of vital importance. The tire vulcanization transfer device effectively avoids the contact of the green tire with other mechanical parts during the transfer process through specially designed bearing blocks and finger plates of the lifting platform, reducing the factors that cause the deformation of the green tire. In addition, the inclination angle of the bearing block is set to 37 degrees, which ensures that the bearing surface only contacts the shoulder of the green tire, avoiding long-term contact between the bearing block and weak parts such as the side of the green tire, thereby reducing the adhesion damage between the side of the green tire and the bearing block, greatly reducing the risk of damage to the green tire surface and contour deformation, ensuring the high quality of the product, and thus improving the reliability of the device in transferring green tires in actual production.

[0053] (4) Low maintenance cost: The tire vulcanization transfer device, which consists of a cart, multiple cylinders, cantilevers and load-bearing blocks, adopts a modular design for easy maintenance and replacement. Key power components such as transport cylinders and lifting cylinders are standardized components with low maintenance costs and high replaceability. Compared with traditional equipment, the device has a longer service life and lower failure rate, thereby reducing maintenance frequency and downtime. In addition, the stable operation of automated equipment also reduces equipment damage caused by human operating errors, further reducing maintenance costs.

[0054] (5) Easy to operate: The tire vulcanization transfer device is easy to operate. It only needs to control the movement of the transport cylinder and the lifting cylinder through buttons to push the cart to dock with the corresponding production line station. Workers only need simple training to master it. The design of the cart makes the entire green tire transfer process more intuitive and simple, reducing the difficulty of operation. The automated coordination of the transport cylinder and the lifting cylinder enables the cart to automatically dock the green tire, move the green tire between the first placement station and the second placement station, and automatically remove the green tire, which not only improves work efficiency, but also reduces the labor intensity of workers and improves work comfort.

[0055] In summary, the tire vulcanization transfer device has significant advantages in improving transfer efficiency, enhancing human-machine safety, reducing green tire deformation to ensure green tire quality, and reducing maintenance costs. It improves the automation level and reliability of the device used for green tire transfer procedures, optimizes the production process, and improves the overall level of tire production, which helps to achieve efficient, stable and high-quality tire production.

The setting of the 37-degree inclination angle 331 is used to make the bearing surface 33 always only contact the shoulder of the green tire, avoiding Avoid contact with other parts of the green tire; the bearing block 3 is suspended on the first placement station 11 and the second placement station 12 by the cantilever 4, at least three bearing blocks 3 are arranged on each station, and multiple bearing blocks 3 are evenly arranged along the circumferential path, and a lifting distance is left between the bearing blocks 3; a plurality of finger plates 231 for lifting the side or shoulder of the green tire are provided on the lifting platform 23; the finger plates 231 are lifted and lowered through the lifting distance as a channel during the lifting process, and are used to lift the green tire on the bearing block 3 or place the green tire on the bearing block 3;

[0081] Transfer by following the steps below:

[0082] When the green tire is being transported, the cart 1 is connected to the green tire lowering device at the first placement station 11. After the green tire lowering device places the green tire on the supporting block 3 of the first placement station 11, the lifting cylinder 22 is extended to drive the lifting platform 23 to lift the green tire on the first placement station 11. Subsequently, the green tire is transported to the second placement station 12 under the drive of the transport cylinder 2. The lifting cylinder 22 retracts to drive the lifting platform 23 to descend and place the green tire on the supporting block 3 of the second placement station 12. Under the protection of the protective frame 13, the cart 1 moves to transfer the green tire to the target location.

[0083] The application of tire vulcanization transfer device can produce the following significant effects on the entire production process of green tire generation, removal, transportation, grabbing, tire vulcanization / temporary storage:

[0084] (1) Improve the transfer efficiency of green tires, thereby improving production efficiency;

[0085] The tire vulcanization transfer device uses the transport cylinder 2, lifting cylinder 22 and lifting platform 23 on the cart 1 in an automated manner, in conjunction with the green tire lowering equipment (truss gripper or EMS), to achieve mechanized green tire docking and green tire transfer between workstations, thereby achieving efficient transfer of green tires from the production line to the vulcanizer.

[0087] The protective frame 13 provided on the second placement station 12 can effectively prevent the green tire from being damaged due to external collision or accidental falling during transportation. It can fully guarantee the integrity of the green tire and reduce the risk of occasional operational errors by workers. Compared with traditional manual handling, the device has a high degree of automation, which reduces the frequency of contact between workers and production line machinery and equipment, thereby reducing potential safety hazards.

[0088] (3) Reduce the deformation of the green tire during transportation;

[0089] During the production process, the integrity and shape quality of the green tire are of vital importance. The tire vulcanization transfer device effectively avoids the contact of the green tire with other mechanical parts during the transportation process through the specially designed bearing block 3 and the finger plate 231 of the lifting platform 23, reducing the factors that cause the deformation of the green tire. In addition, the inclination angle 331 of the bearing block 3 is set to 37 degrees, thereby ensuring that the bearing surface 33 only contacts the shoulder of the green tire, avoiding long-term contact between the bearing block 3 and weak parts such as the side of the green tire, thereby reducing the adhesion damage between the side of the green tire and the bearing block 3, greatly reducing the risk of damage to the green tire surface and contour deformation, ensuring the high quality of the product, and thus improving the reliability of the device in transporting green tires in actual production.

[0090] (4) Low maintenance cost: The tire vulcanization transfer device, which consists of a trolley 1, multiple cylinders, a cantilever 4 and a bearing block 3, adopts a modular design, which is easy to maintain and replace. Key power components such as the transport cylinder 2 and the lifting cylinder 22 are standardized components with low maintenance costs and high replaceability. Compared with traditional equipment, the device has a longer service life and a lower failure rate, thereby reducing maintenance frequency and downtime. In addition, the stable operation of the automated equipment also reduces equipment damage caused by human operating errors, further reducing maintenance costs.

[0091] (5) Easy to operate: The tire vulcanization transfer device is easy to operate. It only needs to control the movement of the transport cylinder 2 and the lifting cylinder 22 through the button 821 to push the cart 1 to dock with the corresponding production line station. Workers only need to undergo simple training to master it. The design of the cart 1 makes the entire green tire transfer process more intuitive and simple, reducing the difficulty of operation. The automated coordination of the transport cylinder 2 and the lifting cylinder 22 enables the cart 1 to automatically dock the green tire, move the green tire between the first placement station 11 and the second placement station 12, and automatically remove the green tire, which not only improves work efficiency, but also reduces the labor intensity of workers and improves work comfort.

[0092] In summary, the tire vulcanization transfer device has significant advantages in improving transfer efficiency, enhancing human-machine safety, reducing green tire deformation to ensure green tire quality, and reducing maintenance costs.

[0093] As one optional implementation,

[0094] Regarding the number of the bearing blocks 3 provided at the workstations on the cart 1 and the specific structure of the lifting platform 23, this embodiment Figures 1 to 4 As shown, four bearing blocks 3 are arranged on the first placement station 11 and the second placement station 12; and the number of finger plates 231 of the lifting platform 23 is four.

[0095] The specific position and movable position of the lifting platform 23, the starting position of the lifting of the lifting platform 23 is set under the cantilever 4 of the supporting block 3, and the lifting platform 23 can reciprocate under the cantilever 4 of the supporting block 3 of the first placement station 11 and the second placement station 12.

[0096] Among them, the transport cylinder 2 can be a combination of a telescopic cylinder and a guide rail slide. The transport cylinder 2 is used as a rodless cylinder, and the transport slide 21 is a slide on the rodless cylinder. This can improve the integration of the moving parts (transport cylinder 2) on the cart 1, reduce the complexity of the mechanism, and improve the reliability of the device.

[0097] During application, four bearing blocks 3 are arranged at each workstation on the cart 1, and a total of four lifting intervals are formed between the four bearing blocks 3, so that the number of finger plates 231 passing through the lifting intervals is set on the lifting platform 23 according to the number of lifting intervals, and the four finger plates 231 intersect vertically in pairs, so that the lifting platform 23 forms a cross-shaped platform; when the lifting platform 23 supports the green tire, the four finger plates 231 can support the green tire in two radial directions and evenly bear the weight of the green tire, so that the lifting platform 23 can support the green tire for lifting and moving in a more stable manner.

[0098] Among them, the transport cylinder 2 and the lifting cylinder 22 on the trolley 1 can be controlled to be extended and retracted by a manual valve, and the air supply of the transport cylinder 2 and the lifting cylinder 22 can be connected through an air pipe for online air supply.

[0099] In order to improve the non-stick performance of the bearing surface 33 of the bearing block 3, the bearing block 3 adopts a mixed material of modified PP and glass fiber. Compared with the existing green tire bearing device "metal pot-shaped device", it has the characteristics of not easy to adhere to the rubber of the green tire, good corrosion resistance, good mechanical properties and high temperature resistance.

[0100] To ensure the stability of the lifting platform 23 when it is lifted and lowered, guide sliders 222 are installed on the opposite sides of the cylinder body of the lifting cylinder 22. A guide rod 221 is slidably connected inside the guide slider 222, and one end of the guide rod 221 is connected to the bottom of the lifting platform 23. When the lifting cylinder 22 is extended or retracted, the guide rod 221 assists the lifting platform 23 in lifting and lowering, so that the telescopic rod of the lifting cylinder 22 that drives the lifting platform 23 only bears a vertical downward force, thereby avoiding the problem that the telescopic rod of the lifting cylinder 22 shakes during the lifting process, thereby affecting the stability of the lifting platform 23 carrying the green tire.

[0101] A second embodiment of the passenger car tire vulcanization adapter 00 is as follows Figure 5 As shown, the difference between this embodiment and the first embodiment is that three bearing blocks 3 are arranged on the first placement station 11 and the second placement station 12; and the number of finger plates 231 of the lifting platform 23 is three.

[0102] During application, three bearing blocks 3 are arranged at each workstation on the cart 1, and a total of three lifting intervals are formed between the three bearing blocks 3, so that the number of finger plates 231 passing through the lifting intervals is set on the lifting platform 23 according to the number of lifting intervals, and the three finger plates 231 are connected to each other at the same center at an interval of 120 degrees, so that the lifting platform 23 forms a star-shaped platform; when the lifting platform 23 supports the green tire, the three finger plates 231 can support the green tire at three equally spaced support points on the annular plane on the side of the green tire, evenly bear the weight of the green tire, and while reducing the number of bearing blocks 3, the lifting platform 23 can still support the green tire for lifting and moving in a smooth manner.

[0103] Based on the above embodiment of the passenger car tire vulcanization transfer device 00, a green tire transfer method is provided, comprising the following steps: S1: a cart 1 is moved to the front or below a green tire lowering device;
