Description

Technical Field

[0001] The utility model relates to the technical field of a vulcanizing machine manipulator tire lifting device, in particular to a tire contactor for a tire vulcanizing machine. Background Art

[0002] A tire vulcanizer is a device used to pressurize and heat a tire blank (also called a green tire) in a cavity surrounded by a mold and an air bag to obtain a tire. The tire loading and unloading system is a key accessory component of the tire vulcanizer. In actual work, the tire loading and unloading system not only needs to grab the tire blank from the side work frame before the vulcanizer starts vulcanizing, and accurately align it and attach it to the bladder of the vulcanizer's central structure, but also needs to be able to automatically remove and unload the shaped tire after the tire blank is vulcanized and formed, so as to start a new round of vulcanization operation.

[0003] In the existing technology, after the tire blank is vulcanized and molded, it is transported to the machine by the AGV automatic logistics system. Currently, personnel manually control the robot to lift the tire. The robot has no tire blank detection structure. When the robot performs automatic tire lifting, it cannot stop accurately according to the height of the tire blank, which can easily press down the tire blank on the tooling and affect the quality of the tire blank. Utility Model Content

[0004] In response to the shortcomings of the existing technology, a tire vulcanizer tire toucher is proposed, which solves the problem in the above-mentioned background technology that the robot arm has no tire blank detection structure, and the robot arm cannot stop accurately according to the height of the tire blank when performing automatic tire lifting, which easily presses the tire blank on the tooling downward.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A tire contactor for a tire vulcanizer includes a frame assembly, which is arranged on a manipulator. A tire contact assembly is slidably connected to the bottom of the frame assembly. A detection assembly is also installed on the frame assembly. The detection assembly controls the movement of the manipulator according to the motion state of the tire contact assembly and the frame assembly to achieve automatic tire lifting.

[0007] Furthermore, the frame assembly includes a first frame fixedly connected to the manipulator, a sliding cavity for sliding the tire contact assembly is provided in the first frame, and the first frame is vertically arranged.

[0008] Furthermore, the tire contact assembly includes a first lifting rod inserted in the first frame, and the first lifting rod is provided with a first spring pin, and the first spring pin is slidably connected to a first limiting groove opened on the first frame.

[0009] Furthermore, the tire contact assembly also includes a tire contact plate for contacting the tire blank, and the tire contact plate is fixedly connected to the bottom of the first lifting rod and is arranged perpendicular to the first lifting rod.

[0010] Furthermore, the frame assembly also includes a second frame arranged parallel to and fixedly connected to the first frame, and the detection assembly is fixedly installed on the second frame to detect the tire contact assembly.

[0011] Furthermore, the detection component includes a fixing plate fixedly connected to the second frame, and a sensor installed on the fixing plate, and the sensor is horizontally arranged.

[0012] Furthermore, a second lifting rod is slidably connected to the second frame, and the sensor is arranged perpendicular to the second lifting rod to detect whether the second lifting rod slides relative to the second frame.

[0013] Furthermore, a second spring pin is fixedly connected to the second lifting rod, and a second limiting groove is provided on the second frame body. The second spring pin is clamped in the second limiting groove to limit the second lifting rod.

[0014] Furthermore, the tire contact plate includes a horizontal plate and an arc-shaped plate, the horizontal plate is fixedly connected below the first lifting rod, and the arc-shaped plate is tilted upward and fixedly connected to one end of the horizontal plate.

[0015] Compared with the prior art, the comprehensive effects brought by the utility model include:

[0016] A frame assembly is provided to support the tire contact assembly and the detection assembly, and a robot is connected at the same time. During the descent of the robot, the tire contact assembly contacts the tire embryo and is pushed up by the tire embryo. When the detection assembly detects that the tire contact assembly has risen, the PLC controls the robot to stop descending and controls the robot to open and grab the tire embryo to realize the transfer and handling of the tire embryo. The above structure prevents the robot from being unable to stop accurately and causing squeezing of the tire embryo, thereby affecting the quality of the tire embryo.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of the present invention.

[0023] In this document, the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", and "top" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0024] like Figures 1 to 4 As shown, a tire vulcanizer tire contactor includes a frame assembly, the frame assembly is arranged on a manipulator, a tire contact assembly is slidably connected to the bottom of the frame assembly, and a detection assembly is also installed on the frame assembly. The detection assembly controls the movement of the manipulator according to the motion state of the tire contact assembly and the frame assembly to realize automatic tire lifting.

[0025] A frame assembly is provided to support the tire contact assembly and the detection assembly, and a robot is connected at the same time. During the descent of the robot, the tire contact assembly contacts the tire embryo and is pushed up by the tire embryo. When the detection assembly detects that the tire contact assembly has risen, the PLC controls the robot to stop descending and controls the robot to open and grab the tire embryo to realize the transfer and handling of the tire embryo. The above structure prevents the robot from being unable to stop accurately and causing squeezing of the tire embryo, thereby affecting the quality of the tire embryo.

[0026] Specifically, during the manipulator's descent, the manipulator remains closed until the tire contactor contacts the tire blank. Upon detecting the rise of the tire contactor assembly, the PLC controls the manipulator to stop descending, determine if the manipulator has reached its designated position, and then open after a five-second delay. Once fully opened, the manipulator ascends to grab and drive the tire blank for transport. With the tire contactor installed, manual tire lifting becomes unnecessary, enabling the vulcanizer manipulator to automatically lift the tire.

[0027] In the tire vulcanizer tire contactor of this embodiment, the frame assembly includes a first frame 1 fixedly connected to the manipulator, a sliding cavity for sliding the tire contact assembly is provided in the first frame 1, and the first frame 1 is vertically arranged.

[0028] Specifically, a first frame 1 is provided to guide the tire-touching assembly, and a sliding cavity is provided for the tire-touching assembly to extend and retract, ensuring that the tire-touching assembly can slide up smoothly after contacting the tire blank for detection, thereby improving detection sensitivity and preventing the tire-touching assembly from squeezing the tire blank.

[0029] In the tire vulcanizer tire contactor of this embodiment, the tire contact assembly includes a first lifting rod 2 inserted into the first frame 1, and a first spring pin 3 is provided on the first lifting rod 2. The first spring pin 3 is slidably connected to the first limiting groove 4 opened on the first frame 1.

[0030] Specifically, two first spring pins 3 are relatively arranged on both sides of the first lifting rod 2, and two corresponding first limiting grooves 4 are also relatively arranged. The first limiting groove 4 is opened at the upper part of the first frame 1. In the initial state, the first spring pin 3 is clamped at the bottom of the first limiting groove 4 to limit the first lifting rod 2 to prevent slipping. When the first lifting rod 2 rises, the first spring pins 3 on both sides slide along the first limiting groove 4 respectively, thereby improving the limiting effect and ensuring that the tire contact assembly moves in the vertical direction.

[0031] In the tire vulcanizer tire contact device of this embodiment, the tire contact assembly also includes a tire contact plate 5 for contacting the tire blank. The tire contact plate 5 is fixedly connected to the bottom of the first lifting rod 2 and is arranged perpendicular to the first lifting rod 2.

[0032] Specifically, a tire contact plate 5 is provided to directly contact the tire embryo. The horizontally provided tire contact plate 5 descends with the manipulator. After contacting the tire embryo, the tire contact assembly fixedly connected to the tire contact plate 5 stops moving and is relatively displaced with the first frame 1 which continues to descend. The detection assembly is used to detect whether the manipulator is in place at this time, thereby achieving the detection purpose and avoiding squeezing the tire embryo.

[0033] In the tire vulcanizer tire contact device of this embodiment, the frame assembly also includes a second frame 6 arranged parallel to and fixedly connected to the first frame 1, and the detection assembly is fixedly mounted on the second frame 6 to detect the tire contact assembly.

[0034] Specifically, the second frame 6 is fixedly connected to the first frame 1 through a connecting plate, and a second lifting rod 8 is slidably connected inside the second frame 6. The bottom end of the second lifting rod 8 is fixedly connected to the tire contact plate 5. Two groups of frames are provided to limit and guide the tire contact assembly, further improving the sliding stability of the tire contact assembly and improving the strength of the tire contact plate 5.

[0035] Preferably, the tire contact plate 5 comprises a horizontal plate and an arcuate plate. The horizontal plate is fixedly connected below the first lifting rod 2 and the second lifting rod 8, while the arcuate plate is tilted upward and fixedly connected to one end of the horizontal plate. This arrangement allows the tire contact plate 5 to better match the cross-sectional shape of the tire blank, improving detection effectiveness.

[0036] In the tire vulcanizer tire detector of this embodiment, the detection component includes a fixing plate 7 fixedly connected to the second frame 6, and a sensor 9 installed on the fixing plate 7, and the sensor 9 is horizontally arranged.

[0037] Specifically, the height of the second frame 6 is smaller than that of the first frame 1, the first lifting rod 2 and the second lifting rod 8 are equal in length, and the fixing plate 7 is L-shaped, with one end perpendicular to the second frame 6 and the other end parallel to the second frame 6. Through the above arrangement, when the tire contact plate 5 drives the two lifting rods to move upward, the second lifting rod 8 can extend out of the second frame 6 to facilitate detection by the sensor 9 fixed on the second frame 6.

[0038] Preferably, the sensor 9 is an infrared sensor. When it is detected that the second lifting rod 8 is extended to block the transmitting end of the sensor 9, it is determined that the manipulator has descended to the tire blank position, and the PLC system controls the manipulator to stop moving to avoid squeezing the tire blank.

[0039] Preferably, the detection component also includes a warning light, which is connected to the sensor 9 signal. When it is detected that the second lifting rod 8 is extended, the warning light lights up to remind the staff to avoid injuring the staff during the movement of the manipulator.

[0040] In the tire vulcanizer tire contactor of this embodiment, the sensor 9 is arranged perpendicular to the second lifting rod 8 to detect whether the second lifting rod 8 slides relative to the second frame 6.

[0041] Specifically, the sensor 9 is installed above the second frame 6. In the initial state, the top of the second lifting rod 8 is not lower than the top of the second frame 6, so as to avoid the second frame 6 blocking the transmitting end of the sensor 9 and affecting the detection effect of the sensor 9 on the second lifting rod 8. When the second lifting rod 8 rises, it is detected by the sensor 9 in time.

[0042] Preferably, in the initial state, the top end of the second lifting rod 8 is at the same height as the top end of the second frame 6, which reduces the overall size of the tire contactor and makes the overall structure of the device more compact.

[0043] In the tire vulcanizer tire contactor of this embodiment, a second spring pin 10 is fixedly connected to the second lifting rod 8, and a second limiting groove is provided on the second frame 6. The second spring pin 10 is clamped in the second limiting groove to limit the second lifting rod 8.

[0044] Specifically, by providing a second spring pin 10 to cooperate with the second limiting groove, the sliding of the second lifting rod 8 in the second frame 6 is guided to improve the movement stability of the tire contact assembly.

[0045] Preferably, the PLC system in this application adopts existing technology, which will not be repeated here. The installation positions of the tire feeler and the manipulator in this application are selected according to actual use to ensure the detection effect of the tire feeler on the tire embryo, while allowing the manipulator to open and accurately grasp the tire embryo.
