Description

Technical Field

[0001] The present invention relates to a loading and unloading device for a carcass tube of a tire embryo and a two-stage forming machine for radial passenger tires, belonging to the technical field of two-stage forming of radial passenger tires. Background Art

[0002] In a traditional two-stage forming machine for radial passenger tires, as Figure 9 shown, in terms of layout, it is basically divided into two main machines: one is a main machine for producing a carcass tube (commonly known as the first-stage main machine), one is a main machine for forming production (commonly known as the second-stage main machine) and a feeding system, and a carcass tube conveying mechanism is also arranged in front of the two main machine lines. The carcass tube conveying mechanism manually places the carcass tube produced on the first-stage main machine by workers on the carcass tube conveying mechanism; the carcass tube conveying mechanism conveys the placed carcass tube to the vicinity of the forming drum of the second-stage main machine, and workers or a mechanism place the carcass tube on the forming drum of the second-stage main machine for the forming process operation. The participation of workers has a certain restriction on the production efficiency of the forming machine. When the carcass tube is conveyed after being manually placed on the carcass tube conveying mechanism, its positioning accuracy and the manual loading on the forming drum of the second-stage main machine line have an impact on the quality of the tire; and it increases the labor intensity of the operators (one more operator is required for manually loading the carcass tube). In the layout of a traditional two-stage forming machine for radial passenger tires, the first-stage main machine line and the second-stage main machine line are basically arranged side by side, and there is at least a passage of not less than 1.5 m left between the two main machine lines; thus increasing the length of the two-stage forming machine for radial passenger tires in the left-right direction. And a carcass tube conveying mechanism also needs to be placed in front of the two main machine lines, thus increasing the length of the two-stage forming machine for radial passenger tires in the front-back direction.
