[0001] The present invention relates to the technical field of tire vulcanization equipment, and specifically relates to a two-station tire storage device and a group-controlled vulcanization unit. Background Art

[0002] The existing two-station tire storage devices generally achieve the switching between the two tire storage stations by means of swing arm rotation or rotation, and sufficient space for the rotation movement needs to be reserved, which results in a large occupied space of the tire storage device and cannot be applied to the vulcanizer cluster. Summary of the Invention

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a two-station tire storage device and a group-controlled vulcanization unit.

[0004] To achieve the above purpose, the technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] A two-station tire storage device includes a frame, a first tire storage device, a second tire storage device and a driving mechanism. The frame is provided with a first station and a second station. Taking the line connecting the centers of the first station and the second station as the X-axis and the vertical plane passing through the X-axis as the XZ plane, the driving mechanism drives the first tire storage device and the second tire storage device to move along the XZ plane direction, and makes the first tire storage device and the second tire storage device alternately switch between the first station and the second station.

[0006] Compared with the prior art, the first tire storage device and the second tire storage device only move within the upper and lower spaces where they are located, without the need for a turning radius space, which is convenient for multiple two-station tire storage devices to be correspondingly arranged one by one with multiple side-by-side vulcanizers, effectively saving the floor area.

[0007] Furthermore, it further includes a first moving frame and a second moving frame. The first tire storage device is fixedly installed on the first moving frame, the second tire storage device is fixedly installed on the second moving frame, the first tire storage device and the second tire storage device are at different heights, and the driving mechanism drives the first moving frame and the second moving frame to move in opposite directions.

[0008] Furthermore, the first moving frame is translatably installed on the frame via a first guide rail, and the driving mechanism includes a first driving mechanism, and the first driving mechanism drives the first moving frame to translate along the first guide rail.

[0009] Furthermore, the second moving frame is translatably installed on the frame via a second guide rail, and the driving mechanism includes a second driving mechanism, and the second driving mechanism drives the second moving frame to translate along the second guide rail.

[0010] With the above - mentioned preferred solution, the first tire storage device and the second tire storage device translate at different heights to realize the switching between the first working station and the second working station.

[0011] Further, the second moving frame is installed on the frame through the first swing frame. The first swing frame includes a first swing arm, a second swing arm and a first connecting arm. The two ends of the first connecting arm are respectively hinged to the lower end of the first swing arm and the lower end of the second swing arm. The middle positions of the first swing arm and the second swing arm are respectively hinged to the frame. The upper ends of the first swing arm and the second swing arm are respectively hinged to the second moving frame. The driving mechanism includes a third driving mechanism. The end of the telescopic rod of the third driving mechanism is hinged to the first swing arm or the second swing arm. The third driving mechanism drives the second moving frame to swing above the first tire storage device through the first swing frame.

[0012] With the above - mentioned preferred solution, the first tire storage device changes positions between the first working station and the second working station in a translational manner, while the second tire storage device changes positions between the first working station and the second working station in a swinging manner. Here, the swinging trajectory is within the vertical space where the first working station and the second working station are located, that is, the radius of rotation is within the vertical space and does not exceed the periphery of the frame.

[0013] Further, the first moving frame and the second moving frame are installed on the frame through the second swing frame. The second swing frame includes a third swing arm and a fourth swing arm. The middle positions of the third swing arm and the fourth swing arm are hinged to the frame. The upper ends of the third swing arm and the fourth swing arm are respectively hinged to the second moving frame. The lower ends of the third swing arm and the fourth swing arm are respectively hinged to the first moving frame. The driving mechanism is a cylinder, a hydraulic cylinder or an electric push rod. The end of the telescopic rod of the driving mechanism is hinged to the third swing arm and the fourth swing arm.

[0014] With the above - mentioned preferred solution, the second tire storage device and the first tire storage device swing synchronously up and down within the vertical space where the first working station and the second working station are located without interfering with each other, which simplifies the structure.

[0015] A group - controlled vulcanizing machine unit includes:

[0016] At least one row of vulcanizing machine single - row combinations. The vulcanizing machine single - row combination includes multiple vulcanizing machines arranged side by side. Each vulcanizing position of each vulcanizing machine is provided with a vulcanizing machine manipulator for putting green tires into the vulcanizing mold and taking out cured tires from the vulcanizing mold.

[0017] At least one common conveying system, which is arranged in parallel with the vulcanizing machine single - row combination. The common conveying system is provided with a common manipulator shared by all the vulcanizing machines in the vulcanizing machine single - row combination. The common manipulator moves along the common conveying system.

[0018] Multiple double-station tire storage devices are provided, with one such device configured at the position between each vulcanizer manipulator and the common conveying system. The double-station tire storage device has a first station and a second station. The vulcanizer manipulator can rotate to the first station of the double-station tire storage device, and the common manipulator can move to the second station of the double-station tire storage device. The double-station tire storage device includes a frame, a first tire storage device, a second tire storage device, and a driving mechanism. The driving mechanism drives the first tire storage device and the second tire storage device to alternately switch between the first station and the second station.

[0019] With the above technical solution, multiple vulcanizers are arranged side by side. The tire loading and unloading of the vulcanizers share a single vulcanizer manipulator on the same side. One row of vulcanizers is equipped with a common conveying system conveyor line. The green tires are fed in and the cured tires are taken away by the common manipulator, and the rapid position switching of the green tires and cured tires is realized in the upper and lower spaces where they are located through the double-station tire storage device between the vulcanizer and the common conveying system. Compared with the usual single-vulcanizer layout, the occupied space and cost are both reduced by about 30%, greatly improving the economic benefits of the tire vulcanization factory.

[0020] Furthermore, a green tire feeding line and a cured tire collecting line are provided at the end of the common conveying system. The green tire feeding line and the cured tire collecting line are respectively located at both ends of the common conveying system or at the same end of the common conveying system. The common manipulator transfers the green tires from the green tire feeding line to each double-station tire storage device, and the common manipulator transfers the cured tires from each double-station tire storage device to the cured tire collecting line.

[0021] With the above preferred solution, the automation level of tire vulcanization production is improved, and the overall layout of the factory is more coordinated and beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The beneficial effect of adopting the above - mentioned technical solution is that the first tire storage device and the second tire storage device only move within the upper and lower spaces where they are located, without the need for a turning radius space, which is convenient for multiple double - station tire storage devices to be correspondingly arranged one by one with multiple side - by - side vulcanizers, effectively saving the floor area.

[0043] The first working station 22 and the second working station 23 here are not limited to a certain horizontal height position, but include a space in the vertical direction with a certain horizontal plane area.
