Description

Technical Field

[0001] This invention belongs to the field of tire vulcanization, and in particular relates to a tire vulcanization production line with one machine and four molds. Background Technology

[0002] Currently, tire vulcanization is generally carried out using a dual-mold vulcanizing machine, and a few use a four-mold vulcanizing machine. However, the movement mode of the vulcanizing chambers in the existing four-mold vulcanizing machine is generally that the two vulcanizing chambers on the same layer move simultaneously or the upper vulcanizing chamber drives the lower vulcanizing chamber to move together. It is impossible to achieve the independent movement of the four vulcanizing chambers without mutual interference, resulting in low utilization rate.

[0003] Moreover, in the existing one-machine-four-mold tire vulcanization production line, the tire blanks are usually transported to the front of the tire vulcanizing machine by a conveyor truss or trailer and placed on the tire storage device in front of the vulcanizing machine. Each of these requires a separate tire blank loading device, tire unloading device, rear inflation device, and tire conveying line. These devices are not only complex in structure, but also occupy a large area and are complicated to operate.

[0004] Therefore, the existing one-machine-four-mold tire vulcanization production line has problems such as complex structure, large footprint, complicated operation, high labor intensity, low production efficiency and utilization rate, and high operation and maintenance costs. Summary of the Invention

[0005] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects and advantages of the present application more readily apparent.

[0006] This invention proposes a one-machine-four-mold tire vulcanization production line, which solves the technical problems of existing one-machine-four-mold tire vulcanization production lines, such as complex structure, large footprint, complicated operation, high labor intensity, low production efficiency and utilization, and high operation and maintenance costs. It not only simplifies the structure and centralizes the functions of the one-machine-four-mold tire vulcanization production line, but also greatly reduces the footprint, reduces labor intensity, improves production efficiency and utilization, and reduces operation and maintenance costs.

[0007] This invention discloses a four-stage tire vulcanization production line, including a vulcanizing machine, a post-inflation device, and an automated production line. The post-inflation device is spaced apart from the vulcanizing machine and has multiple inflation stations, which can inflate individually or simultaneously. The automated production line is located between the vulcanizing machine and the post-inflation device, and can realize the transportation of green tires before vulcanization and the transportation of finished vulcanized tires.

[0008] In some embodiments, the one-machine-four-mold tire vulcanization production line also includes a robotic arm device, which is located between the vulcanizing machine and the post-inflation device and above the automated production line. The robotic arm device can realize the loading of the green tires before vulcanization and the unloading of the finished tires after vulcanization.

[0009] In some embodiments, the automated production line has two parallel sections, one above the other. The automated production line includes a base, a mounting base, two tire holders, two tire conveyor lines, and a motor. The mounting base is located on the base. The two tire holders are spaced apart on the mounting base to store the green tires before vulcanization. The two tire conveyor lines are spaced apart on the mounting base to convey the vulcanized finished tires. The motor is located on the base and controls the tire holders and tire conveyor lines to move to the area below the robotic arm device.

[0010] In some embodiments, the mounting base is provided with a second cylinder, the second cylinder is provided with a positioning pin, and the base is provided with a positioning hole. The mounting base drives the second cylinder to move. When the positioning pin on the second cylinder cooperates with the positioning hole, the positioning of the tire retainer and the tire delivery line can be realized.

[0011] In some embodiments, the vulcanizing machine has four vulcanizing chambers, which can be vulcanized individually or simultaneously. The vulcanizing machine includes a lower base, an upper base, and a middle beam. The lower base is located at the bottom of the vulcanizing machine; the upper base is positioned opposite the lower base and at the top of the vulcanizing machine; the middle beam is located between the lower base and the upper base, with two upper vulcanizing chambers above the middle beam and two lower vulcanizing chambers below the middle beam. Each chamber has two upper guide columns, located on the left and right sides of the upper vulcanizing chamber. One end of each upper guide column is fixedly connected to the upper base, and the other end is threadedly connected to the intermediate beam. Similarly, each of the two lower vulcanizing chambers has two lower guide columns, located on the left and right sides of the lower vulcanizing chamber. One end of each lower guide column is fixedly connected to the lower base, and the other end is threadedly connected to the intermediate beam.

[0012] In some embodiments, the upper vulcanization chamber includes an upper movable beam, an upper upper mold, and an upper lower mold. The upper movable beam can move up and down along the upper guide column. The upper upper mold is fixed to the center of the upper movable beam and can move up and down along the upper guide column with the upper movable beam. The upper lower mold is fixedly connected to the intermediate beam.

[0013] In some embodiments, the lower vulcanizing chamber includes a lower movable beam, a lower upper mold, and a lower lower mold. The lower movable beam can move up and down along the lower guide column. The lower upper mold is fixedly connected to the intermediate beam. The lower lower mold is fixed at the center of the lower movable beam and can move up and down along the lower guide column with the lower movable beam.

[0014] In some embodiments, the post-inflation device has four inflation chambers, each corresponding to one of the four vulcanization chambers, and each inflation chamber has an upper inflation station and a lower inflation station.

[0015] In some embodiments, the inflation chamber includes a first cylinder, a locking mechanism, and an adjusting device. The locking mechanism is connected to the first cylinder, and the first cylinder drives the locking mechanism to move up and down to control the locking and unlocking of the upper inflation station and the lower inflation station. The upper inflation station and the lower inflation station can be inflated individually or simultaneously. The adjusting device is disposed opposite to the locking mechanism to control the position of the upper inflation station and the lower inflation station.

[0016] In some embodiments, the robotic arm device includes a robotic arm, a connecting seat, a lifting device, a rotating device, and a gripping device. The connecting seat is connected to the vulcanizing machine; the lifting device is connected to the connecting seat to control the up-and-down movement of the robotic arm; the rotating device is connected to the lifting device to control the rotation of the robotic arm; and the gripping device is connected to the rotating device to control the robotic arm's tire picking and releasing.

[0017] Another aspect of the present invention discloses a tire manufactured using the aforementioned method for manufacturing engineering machinery tires.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention integrates a vulcanizing machine, a post-inflation device, and an automated production line into one unit. It can provide a comprehensive solution for the construction of a tire factory's vulcanizing workshop, including the transportation of green tires before vulcanization, the vulcanization of green tires, the inflation and cooling of vulcanized tires, and the transportation of vulcanized finished tires. It integrates these actions into one unit to achieve automation, providing a new approach to tire factory construction planning. This one-machine-four-mold tire vulcanizing production line not only simplifies the structure and centralizes the functions of the one-machine-four-mold tire vulcanizing production line, but also greatly reduces the floor space, reduces labor intensity, improves production efficiency and utilization, and reduces operation and maintenance costs.

[0020] 2. This invention, by placing an automated production line between the vulcanizing machine and the post-inflation device, enables the transportation of green tires before vulcanization and finished tires after vulcanization. The automated production line in this invention can transport both green tires before vulcanization and finished tires after vulcanization, thus fulfilling the dual function of transporting both green and finished tires. Currently, the transportation of green tires before vulcanization is usually carried out by an automated conveyor gantry or trailer to the front of the tire vulcanizing machine, and then placed on the tire storage container in front of the vulcanizing machine. Therefore, a certain amount of space needs to be left in front of the vulcanizing machine to store green tires. However, this invention, by placing the automated production line between the vulcanizing machine and the post-inflation device, reduces the transportation space for green tires and effectively reduces the floor space occupied. Compared with the existing tire vulcanizing production line, the floor space occupied can be reduced by 1 / 3.

[0021] 3. This invention, by placing the robotic arm device between the vulcanizing machine and the post-inflation device, and above the automated production line, enables the loading of green tires before vulcanization and the unloading of finished tires after vulcanization. This effectively solves the technical problem that green tires before vulcanization need to be transported to the front of the tire vulcanizing machine using automated conveyor trusses or trailers, and that robotic arms need to be placed both in front of and behind the vulcanizing machine to complete the loading and unloading, resulting in a complex structure and large footprint. This application combines the loading and unloading functions of the robotic arm device into one, which not only greatly saves the footprint but also achieves automation and significantly improves production efficiency.

[0022] 4. In the automated production line of this invention, the tire holder and tire conveyor are controlled by a motor to be transported to the bottom of the robotic arm device. However, relying solely on the motor to control the position of the tire holder and tire conveyor cannot achieve accurate positioning. Therefore, this invention provides a second cylinder with a positioning pin on the mounting base, and a positioning hole is installed on the base to accurately position the tire holder and tire conveyor. After the positioning pin is inserted into the positioning hole, the tire holder and tire conveyor can be accurately positioned, enabling the robotic arm to accurately grasp the tires during loading and unloading, preventing the tires from deviating from the robotic arm and causing inaccurate grasping and tires to fall off.

[0023] 5. The vulcanizing machine designed in this invention has four vulcanizing chambers, which provides a new design concept compared with the existing vulcanizing machines with four vulcanizing chambers. The tires in the four vulcanizing chambers can be vulcanized simultaneously or individually. When vulcanizing individually, the tires in each vulcanizing chamber do not interfere with each other during the vulcanization process. When one vulcanization is completed, the tires in the other three vulcanizing chambers can continue to vulcanize normally without stopping, which greatly improves the flexibility and utilization rate of the vulcanizing machine, and also improves production efficiency.

[0024] 6. This invention provides a novel design by installing an intermediate beam within the vulcanizing machine, which divides the machine into two upper vulcanizing chambers and two lower vulcanizing chambers. The upper lower mold in the upper vulcanizing chamber is fixed to the intermediate beam, and its opening and closing action is achieved by the up-and-down movement of the upper mold. Similarly, the lower upper mold in the lower vulcanizing chamber is fixed to the intermediate beam, and its opening and closing action is achieved by the up-and-down movement of the lower mold. This mold-opening and closing structure offers a new design approach compared to existing vulcanizing machines where only the upper mold can move up and down to achieve the opening and closing action.

[0025] 7. The post-inflation device designed in this invention has four inflation chambers, which correspond one-to-one with the four vulcanization chambers. Each inflation chamber has an upper inflation station and a lower inflation station, that is, one vulcanization chamber corresponds to two inflation stations. Therefore, the post-inflation device in this invention has a total of eight inflation stations, and the eight inflation stations can realize individual inflation or simultaneous inflation. When the upper inflation station and the lower inflation station in one of the inflation chambers are inflated at the same time, the inflation action can be realized by locking the locking mechanism at the same time. When any inflation station is inflated, the locking mechanism of this inflation station must be locked, while the other station that does not need to be inflated is released.

[0039] This invention provides a method for manufacturing engineering machinery tires. Figure 1 This is a left view of a one-machine-four-mold tire vulcanization production line according to an embodiment of the present invention, as shown below. Figure 1 As shown, the one-machine-four-mold tire vulcanization production line includes a vulcanizing machine 1, a post-inflation device 2, and an automated production line 3. The post-inflation device 2 is arranged at intervals from the vulcanizing machine 1. The post-inflation device 2 has multiple inflation stations, which can be inflated individually or simultaneously. The automated production line 3 is located between the vulcanizing machine 1 and the post-inflation device 2. The automated production line 3 can realize the transportation of green tires before vulcanization and the transportation of finished tires after vulcanization. This invention integrates the vulcanizing machine 1, the post-inflation device 2, and the automated production line 3 into a single unit, centralizing functions to form an automated production line for transportation, tire loading, vulcanization, inflation, tire unloading, and re-transportation. This provides a comprehensive solution for the construction of vulcanization workshops in tire factories, encompassing the transportation of green tires before vulcanization, the vulcanization of green tires, the inflation and cooling of vulcanized tires, and the transportation of finished vulcanized tires. By integrating these actions into a single, automated system, it offers new ideas for tire factory construction planning. This invention's one-machine-four-mold tire vulcanization production line not only simplifies the structure and centralizes functions, but also significantly reduces floor space, lowers labor intensity, increases production efficiency and utilization, and reduces maintenance costs.

[0040] In some embodiments, the present invention places the automated production line 3 between the vulcanizing machine 1 and the post-inflation device 2, which can realize the transportation of green tires before vulcanization and the transportation of finished tires after vulcanization. The automated production line 3 in the present invention can transport both green tires before vulcanization and finished tires after vulcanization, taking into account both functions of transporting green tires and finished tires. The existing transportation of green tires before vulcanization usually uses automated conveyor gantry or trailer to transport them to the front of the tire vulcanizing machine, and then place them on the tire storage device in front of the vulcanizing machine. Therefore, a certain space needs to be left in front of the vulcanizing machine 1 to store green tires. However, the present invention places the automated production line 3 between the vulcanizing machine 1 and the post-inflation device 2, which reduces the transportation space of green tires and effectively reduces the floor area. Compared with the existing tire vulcanizing production line, the floor area can be reduced by 1 / 3.

[0041] Furthermore, such as Figure 1 As shown, the one-machine-four-mold tire vulcanization production line also includes a robotic arm device 4. The robotic arm device 4 is located between the vulcanizing machine 1 and the post-inflation device 2, and above the automated production line 3. The robotic arm device 4 can realize the loading of green tires before vulcanization and the unloading of finished tires after vulcanization. This invention places the robotic arm device 4 between the vulcanizing machine 1 and the post-inflation device 2, and above the automated production line 3, which can realize the loading of green tires before vulcanization and the unloading of finished tires after vulcanization. It can effectively solve the technical problems of the need to use automated conveyor gantry or trailer to transport green tires to the front of the vulcanizing machine 1 during the transportation process before vulcanization, and the need to set up robotic arms in front of and behind the vulcanizing machine 1 to complete the loading and unloading of tires, which is complex in structure and occupies a large area. This application combines the loading and unloading functions of the robotic arm device 4 into one, which not only saves a lot of space, but also realizes automation and greatly improves production efficiency.

[0042] Furthermore, such as Figure 1 and Figure 5 As shown, the automated production line has two sections, one above the other. The automated production line includes a base 301, a mounting base 302, two tire holders 303, two tire conveyor lines 304, and a motor 305. The mounting base 302 is located on the base 301. The two tire holders 303 are spaced apart on the mounting base 302 and are used to store green tires before vulcanization. The two tire conveyor lines 304 are spaced apart on the mounting base 302 and are used to convey vulcanized finished tires. The motor 305 is located on the base 301 and controls the tire holders 303 and tire conveyor lines 304 to move to the bottom of the robotic arm device 4. In this invention, the base 301 is fixed to the ground and the second-floor platform. The base 301 is stationary. The mounting base 302 is located on the base 301 and is provided with two tire retainers 303 and two tire conveying lines 304. The mounting base 302 can drive the two tire retainers 303 and the two tire conveying lines 304 to move on the base 301.

[0043] In some embodiments, the motor 305 on the automated production line is preferably a servo motor, and a displacement sensor is used to control the tire holder 303 and the tire conveyor line 304 to move below the corresponding robotic arm device 4. Furthermore, a displacement sensor can also be installed on the automated production line to control the position of the tire holder 303 and the tire conveyor line 304.

[0044] Furthermore, such as Figures 5-7 As shown, the present invention provides a second cylinder 306 on the mounting base 302, a positioning pin 307 on the second cylinder 306, and a positioning hole 308 on the base 301. The mounting base 302 drives the second cylinder 306 to move. When the positioning pin 307 on the second cylinder 306 cooperates with the positioning hole 308, the tire retainer 303 and the tire conveying line 304 can be accurately positioned. In order to make the positioning of the tire holder 303 and the tire conveying line 304 more accurate, the present invention provides a second cylinder 306 with a positioning pin 307 on the mounting base 302, and a positioning hole 308 is installed on the base 301 to enable the accurate positioning of the tire holder 303 and the tire conveying line 304. After the positioning pin 307 is inserted into the positioning hole 308, the accurate positioning of the tire holder 303 and the tire conveying line 304 can be achieved, so that the robot arm 401 can accurately grasp the tire when loading and unloading the tire, and prevent the tire from deviating from the robot arm 401, which would cause the robot arm 401 to lose its gripping position and the tire to fall off.

[0045] Furthermore, such as Figure 2 As shown, the vulcanizing machine 1 has four vulcanizing chambers, which can be vulcanized individually or simultaneously. The vulcanizing machine 1 includes a lower base 13, an upper base 14, and a middle beam 15. The lower base 13 is located at the bottom of the vulcanizing machine 1; the upper base 14 is positioned opposite the lower base 13 and is located at the top of the vulcanizing machine 1; the middle beam 15 is located between the lower base 13 and the upper base 14. Two upper vulcanizing chambers 11 are located above the middle beam 15, and two lower vulcanizing chambers 12 are located below the middle beam 15. Each of the two upper vulcanizing chambers 11 contains two... Two upper guide columns 111 are respectively located on the left and right sides of the upper vulcanizing chamber 11. One end of each upper guide column 111 is fixedly connected to the upper base 14, and the other end is threadedly connected to the intermediate beam 15. Two lower guide columns 121 are respectively located on the left and right sides of the lower vulcanizing chamber 12. One end of each lower guide column 121 is fixedly connected to the lower base 13, and the other end is threadedly connected to the intermediate beam 15. This invention uses threaded connections between the upper guide columns 111 and the lower guide columns 121 and the intermediate beam 15, which is not only more secure than the existing method of fixing guide columns only with retaining rings, but also facilitates disassembly.

[0046] Furthermore, such as Figure 2 As shown, the upper vulcanizing chamber 11 includes an upper movable beam 112, an upper upper mold 113, and an upper lower mold 114. The upper movable beam 112 can move up and down along the upper guide column 111. The upper upper mold 113 is fixed at the center of the upper movable beam 112 and can move up and down along the upper guide column 111 with the upper movable beam 112. The upper lower mold 114 is fixedly connected to the intermediate beam 15. In this invention, the upper lower mold 114 is fixedly connected to the intermediate beam 15, so that the upper lower mold 114 is stationary, while the upper upper mold 113 can move up and down along the upper guide column 111 with the upper movable beam 112, thereby realizing the mold opening and closing action.

[0047] Furthermore, such as Figure 2 As shown, the lower vulcanizing chamber 12 includes a lower movable beam 122, a lower upper mold 123, and a lower lower mold 124. The lower movable beam 122 can move up and down along the lower guide column 121. The lower upper mold 123 is fixedly connected to the intermediate beam 15. The lower lower mold 124 is fixed at the center of the lower movable beam 122 and can move up and down along the lower guide column 121 with the lower movable beam 122. This invention fixes the lower upper mold 123 to the intermediate beam 15, making the lower upper mold 123 stationary while the lower lower mold 124 can move up and down along the lower guide column 121 with the lower movable beam 122, thus realizing the mold opening and closing action. This mold opening and closing structure provides a new design concept compared to the existing vulcanizing machine structure where only the upper mold can move up and down to realize the mold opening and closing action.

[0048] Furthermore, such as Figure 4 As shown, the post-inflation device 2 has four inflation chambers 21, each corresponding to one of the four vulcanization chambers. Each inflation chamber 21 has an upper inflation station 211 and a lower inflation station 212. In this invention, the four inflation chambers 21 correspond one-to-one with the four vulcanization chambers, and each inflation chamber 21 has an upper inflation station 211 and a lower inflation station 212. That is, one vulcanization chamber corresponds to two inflation stations. Therefore, the post-inflation device 2 in this invention has a total of eight inflation stations, and these eight inflation stations can achieve individual or simultaneous inflation. When inflation is performed individually, each inflation station can avoid mutual interference, greatly improving the flexibility and utilization rate of the inflation stations.

[0049] Furthermore, such as Figure 4 As shown, the inflation chamber 21 includes a first cylinder 213, a locking mechanism 214, and an adjusting device 215. The locking mechanism 214 is connected to the first cylinder 213. The first cylinder 213 drives the locking mechanism 214 to move up and down, thereby controlling the locking and opening of the upper inflation station 211 and the lower inflation station 212. The upper inflation station 211 and the lower inflation station 212 can be inflated individually or simultaneously. The adjusting device 215 is arranged opposite to the locking mechanism 214 to control the position of the upper inflation station 211 and the lower inflation station 212.

[0050] In some embodiments, the upper inflation station 211 and the lower inflation station 212 in the inflation chamber 21 are both lifting structures. The locking mechanism 214 is raised and lowered by the first cylinder 213 to lock and open the upper inflation station 211 and the lower inflation station 212. When the upper inflation station 211 and the lower inflation station 212 in one inflation chamber 21 need to be inflated at the same time, the locking mechanism 214 is raised and lowered by the first cylinder 213 to lock both the upper inflation station 211 and the lower inflation station 212. When any one inflation station is inflated, the locking mechanism of this inflation station is raised and lowered by the first cylinder 213 to lock it, while the other station that does not need to be inflated is released. In actual use, the upper inflation station 211 and the lower inflation station 212 are locked and released alternately.

[0051] Furthermore, such as Figure 3 As shown, the robotic arm device 4 includes a robotic arm 401, a connecting seat 402, a lifting device 403, a rotating device 404, and a gripping device 405. The connecting seat 402 is connected to the vulcanizing machine 1; the lifting device 403 is connected to the connecting seat 402 and is used to control the up and down movement of the robotic arm 401; the rotating device 404 is connected to the lifting device 403 and is used to control the rotation of the robotic arm 401; the gripping device 405 is connected to the rotating device 404 and is used to control the robotic arm 401 to pick up and release tires.

[0052] In some embodiments, two robotic arms 4 are provided, one located above the automated production line 3 on the ground and the other located above the automated production line 3 on a second-floor platform, both positioned in the middle of the vulcanizing machine 1. The robotic arm 4 has two robotic arms 401, left and right, which can respectively operate the left and right vulcanizing chambers and inflation chambers for tire loading and unloading. The two robotic arms 401 are independent of each other and can be operated simultaneously or individually. Furthermore, the lifting device 403 is equipped with a motor for controlling lifting, preferably a servo motor. The servo motor drives the lifting device 403 to move the rotating device 404 and the gripping device 405 to a specified height and position, enabling the robotic arm 4 to flexibly load tires at different heights before vulcanization and unload finished tires after vulcanization, thus having a wide range of applications.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent.
