[0026] In order to solve the problem that the carcass barrel feeding device in the prior art is relatively complicated as a whole, the utility model provides a barrel transfer device and a tire building machine, wherein the tire building machine includes the following barrel transfer device.

[0027] like Figures 1 to 5 A barrel transfer device shown includes a base 10, a spreader 20 for sleeved barrel, and a cloth pulling ring 30, wherein the spreader 20 is coaxially arranged with a drum body 60; the cloth pulling ring 30 is arranged on the base and can move between the spreader 20 and the drum body 60, the cloth pulling ring 30 includes a ring body 31 and a clamping jaw assembly 32, the ring body 31 has an annular structure coaxial with the spreader 20, the clamping jaw assembly 32 is connected to the ring body 31 and is located on the circumferential side of the annular structure, the clamping jaw assembly 32 has a clamping area, and the entrance side of the clamping area is oriented parallel to the axial direction of the annular structure.

[0028] In this embodiment, the design of the pull ring 30 allows the spreader 20 and the pull ring 30 to cooperate to transfer the barrel to the drum body 60, thereby completing the transfer of the barrel, thereby improving production efficiency, saving production cycles, and reducing overall production costs. Specifically, on the one hand, the pull ring 30 is arranged on the base, and can move between the spreader 20 and the drum body 60 along the axis of the spreader 20 and the drum body 60 to meet the transfer of the carcass barrel 50 between the spreader 20 and the drum body 60. On the other hand, the pull ring 30 has an annular structure coaxial with the spreader 20, and a clamping claw assembly 32 is arranged on the circumferential side of the annular structure, and cooperates with the entrance of the clamping area. When the clamping area formed by the clamping jaw assembly 32 moves to the designated position on one side of the spreader 20, the carcass tube 50 can be clamped, and the pull ring 30 drives the carcass tube 50 to move axially to the designated position, thereby transferring the carcass tube 50 from the spreader 20 to the drum body 60. In this way, the carcass tube 50 can be made by other equipment, and no special equipment such as a separate feed rack is required, which simplifies the complexity of the overall structure and reduces the overall cost. For the production of relatively large tires such as agricultural tires and engineering tires, it has the advantages of small footprint and low equipment demand cost, and the carcass tube is transferred by the pull ring 30, and the whole process is completed automatically. Reduce manual intervention in the relative position of the carcass tube and the drum body, improve production efficiency, and improve the quality of the tire.

[0029] It should be noted that the movement of the cloth pulling ring 30 on the base along the axial direction of the spreader 20 can be driven by a motor.

[0030] In this embodiment, there are multiple clamping jaw assemblies 32, so that the clamping of the carcass tube 50 is more firm and reliable. Each clamping jaw assembly 32 is arranged at intervals along the circumference of the annular structure to form an annular structure, so as to evenly clamp the circumference of the carcass tube 50, so that the circumference of the carcass tube 50 can be evenly stressed, prevent the carcass tube 50 from being deformed, and ensure the effect of driving the carcass tube 50 to move. At the same time, in this embodiment, the clamping area is also arranged on the inner side of the annular structure, so that when the clamping jaw assembly 32 approaches the spreader 20 or the drum body 60 to clamp or release the carcass tube 50, the carcass tube 50 is located between the spreader 20 or the drum body 60 and the cloth pull ring 30, and they do not interfere with each other.

[0031] In this embodiment, the barrel transfer device further includes a sliding assembly 40, which is disposed between the clamping jaw assembly 32 and the ring body 31, and the clamping jaw assembly 32 can move relative to the ring body 31 along the radial direction of the annular structure through the sliding assembly 40, so that the clamping jaw assembly 32 can expand and contract along the radial direction of the annular structure, thereby changing the diameter of the annular clamping area, so that the clamping jaw assembly 32 can clamp carcass barrels 50 of different sizes, and increase the working range of the cloth pulling ring 30. This embodiment does not limit the structure of the sliding assembly 40, and the sliding assembly 40 can be a slideway slider structure, a guide rail structure, etc., and can be driven by a motor or a cylinder, and can adjust the radial position of the clamping jaw assembly 32.

[0032] like Figure 3 As shown, in this embodiment, the clamping jaw assembly 32 includes a mounting seat 321, a clamping member 322, and a driving member 323. The mounting seat 321 is connected to the base 10, so that the clamping jaw assembly 32 can move along the axial direction of the spreader 20 with the base 10. The clamping member 322 is movably connected to the mounting seat 321. The mounting seat 321 has a clamping portion. The clamping member 322 and the clamping portion form a clamping area. The side surfaces of the clamping member 322 opposite to the clamping portion, that is, the inner wall surface of the clamping area can be set as a wavy curved surface, thereby helping to enhance the reliability of clamping; the driving member 323 is drivingly connected to the clamping member 322. The driving member 323 can be set as a cylinder, which is used to drive the clamping member 322 to move relative to the clamping portion to change the size of the clamping area and realize the clamping and release of the tire body tube 50.

[0033] In this embodiment, the mounting seat 321 includes a first section, a second section and a third section. The first section is slidably connected to the ring body 31, so that the radial position of the clamping jaw assembly 32 relative to the annular structure is changed by the movement between the first section and the ring body 31, so that the clamping jaw assembly 32 can adapt to the carcass tube 50 of different sizes. The second section and the third section are both connected to the first section, and the second section and the third section are both extended along the axial direction of the annular structure, so that the second section and the third section form a parallel matching relationship. Further, the second section and the third section of this embodiment are both vertically connected to the first section. The side wall of the second section, more specifically, the side of the second section close to the third section, serves as a clamping portion. Accordingly, the clamping member 322 is located between the second section and the third section. In this way, a clamping area can be formed between the clamping member 322 and the clamping portion, and the size of the clamping area can be changed by following the position change of the clamping member 322, so as to achieve clamping and release. In this embodiment, the ends of the second section and the third section that are close to each other are connected to the first section, so that the free ends of the second section and the third section are located in the same direction. Based on the formation of the above-mentioned clamping area, the entrance side of the so-called clamping area is essentially the side where the ends of the second section and the third section away from the first section are located.

[0034] In general, the mounting base 321 of the present embodiment has an F-shaped structure, wherein the longitudinal portion is the first section, and the two transverse portions are the second section and the third section. Figure 3 Taking the clamping jaw assembly 32 located at the upper part of the annular structure as an example, the mounting seat 321 at this position is an inverted F-shaped structure, wherein the longitudinal segment is the first segment, the lower segment of the two transverse segments is the second segment, and the upper segment is the third segment. The second segment and the third segment are arranged opposite to each other, the upper surface of the second segment is used as a clamping portion, and a clamping member 322 is arranged on the lower side of the third segment, thereby forming a clamping area between the upper surface of the second segment and the lower surface of the clamping member 322, and the entrance side of the clamping area is the left side. Of course, the specific structural form of the mounting seat 321 is not limited to the above-mentioned setting mode of this embodiment, and other structural forms can be adopted as needed.

[0035] Optionally, the second section and the inlet side end of the clamping member 322 can be set to a wedge shape to increase the opening area on the inlet side of the clamping area, so that the carcass tube 50 can enter the clamping area more smoothly and facilitate the clamping of the jaw assembly 32.

[0036] In this embodiment, the clamping jaw assembly 32 also includes a transmission rod 324, and the clamping member 322, the driving member 323 and the mounting seat 321 are all driven and connected to the transmission rod 324. The driving member 323 drives the clamping member 322 to move relative to the clamping part through the transmission rod 324, thereby adjusting the distance between the clamping member 322 and the clamping part, thereby clamping or releasing the tire body tube 50.

[0037] Specifically, in this embodiment, the driving member 323 and the clamping member 322 are located on opposite sides of the third section, and the two ends of the transmission rod 324 are rotatably connected to the driving member 323 and the clamping member 322 respectively. The transmission rod 324 is rotatably connected to the third section and the connection is located between the two ends of the transmission rod 324. That is, one end of the transmission rod 324 is connected to the driving member 323, and the other end is connected to the clamping member 322. According to the movement distance requirement of the clamping member 322, a point is selected between the two ends of the transmission rod 324 to be connected to the second section of the mounting seat 321, so that when the driving member 323 drives one end of the transmission rod 324 to move away from or close to the first section of the mounting seat 321, the other end drives the clamping member 322 to move in the direction of the third section close to or away from the mounting seat 321, thereby clamping or releasing the carcass tube 50. Based on the aforementioned Figure 3 In the structural form, the driving member 323 of this embodiment is located above the third section, the middle part of the transmission rod 324 is pivotally connected to the third section, the lower end of which is rotatably connected to the clamping member 322, and the upper end is matched with the driving member 323. When the driving member drives the upper end to move, the transmission rod 324 can rotate as a whole, thereby realizing the movement of the clamping member 322 relative to the clamping part, and realizing the clamping and releasing actions.

[0038] In this embodiment, the output end of the driving member 323 has a transfer shaft, and one end of the transmission rod 324 has a rotating shaft, and the transfer shaft is rotatably mounted on the outside of the rotating shaft. The reason for adopting the above-mentioned arrangement is that when the transmission rod 324 rotates as a whole, the up and down position of its upper end will also change. Therefore, a rotating shaft is rotatably provided on the upper end of the transmission rod 324, and the transfer shaft is rotatably mounted on the rotating shaft. In this way, the lateral driving force of the driving member 323 can be transmitted to the transmission rod 324 through the transfer shaft. Even if the up and down position of the upper end of the transmission rod 324 changes, it can ensure that the transmission rod 324 and the driving member 323 always maintain a driving matching relationship, thereby realizing the reliability of the rotation drive of the transmission rod 324.

[0039] In this embodiment, the clamping jaw assembly 32 further includes a connecting rod 325, the two ends of which are rotatably connected to the third section and the clamping member 322, respectively. The function of the connecting rod 325 is to cooperate with the transmission rod 324 to assist the movement of the clamping member 322, so as to ensure that the clamping member 322 as a whole is close to or away from the clamping portion, and avoid tilting. Figure 3 Specifically, the clamping member 322 can move up and down as a whole so as to be close to or away from the clamping portion, thereby clamping or releasing the carcass tube 50.

[0040] In this embodiment, the clamping jaw assembly 32 can also be provided with a sensor position detection function, and the sensor detects the gripping starting position of the carcass tube 50, which can adapt to the error caused by manual feeding and ensure the fitting accuracy.

[0041] The barrel transfer device in this embodiment is integrated on a section of the main machine of the tire building machine. The carcass barrel 50 completed in the previous process is manually loaded to the spreader 20, and the spreader 20 expands. The clamping claw assembly 32 of the pull ring 30 moves radially to the specified size and then opens the clamping claw assembly 32. The clamping claw assembly 32 moves axially so that one end of the carcass barrel 50 is located in the clamping area. The clamping piece 322 and the clamping arm cooperate to clamp one end of the carcass barrel 50. The pull ring 30 drives the carcass barrel 50 to move axially to the specified position, and the carcass barrel 50 is transferred from the spreader 20 to the drum 60. The clamping claw assembly 32 releases the carcass barrel 50, and the pull ring 30 returns to the original position. This process completes the transfer of the carcass barrel 50. When used specifically, the main process is as follows: the carcass barrel 50 is manually loaded to the spreader 20, the spreader 20 expands to the set diameter, and the clamping claw assembly 32 of the pull ring 30 is driven by the sliding assembly 40 to expand to the corresponding diameter. The clamping jaw assembly 32 opens, and the motor drives the entire cloth pulling ring 30 to move axially from the origin to the position of taking the carcass tube 50. After the sensor on the clamping jaw assembly 32 detects the carcass tube 50, the clamping member 322 and the clamping arm clamp the carcass tube 50. The cloth pulling ring 30 clamps the carcass tube 50 and moves axially. After moving to the position of the carcass tube 50, the clamping jaw assembly 32 is released, and the transfer of the carcass tube 50 is completed, that is, it is transferred from the expander 20 to the drum body 60. After the transfer is completed, the cloth pulling ring 30 returns to the origin.
