Prior art carcass assembly delivery devices often have the following major drawbacks:

1. If the mechanical clamping actuator is used, under the condition of long-term high-frequency swinging motion and linear motion, the moving joint is easy to cause wear, which causes the moving parts to produce a vibrating and serpentine trajectory, which significantly affects The accuracy of the clamping and transfer of the bead and the carcass member adversely affects the dynamic balance and uniformity of the green tire molding.

2. If the vacuum chuck type clamping actuator is used, the requirements for gas source stability are high, and the vacuum chuck is easy to be damaged, resulting in an increase in maintenance cost.

Summary of the invention

The carcass assembly transfer device and the transfer method thereof according to the present invention solve the defects and deficiencies of the prior art described above, and adopt an array drive combination device carcass removal device between the ring body and the transfer actuator to The driving force of the driving device is transmitted and converted into the thrust pushing the actuator in the radial direction, thereby improving the consistency and operation precision of the plurality of executing terminals, and improving the clamping force control for the carcass member and the bead Accurate, avoid problems such as slippage or deformation of the carcass assembly caused by improper clamping force.

Another object of the invention is to effectively reduce the wear between the motion guide and the clamping actuator under conditions of long-term high-frequency rotational oscillation and linear motion, and to improve the smoothness of the driving force transmission.

It is also an object of the invention to improve the control of the telescopic accuracy of the grip actuator to be applied to the accurate transfer of the carcass components of various models and sizes.

In order to achieve the above object, the carcass assembly transfer device mainly comprises:

a carcass center ring for reciprocating sliding through the bottom or top sliding track, a left bead transfer ring and a right bead transfer ring for transmitting left and right beads, and for performing sidewall expansion Side wall expansion Ring. The difference from the prior art is that

The carcass center ring has a ring body, and an array driving combination device and a carcass removal device are disposed on the ring body, and a carcass removal claw is installed at an end of each group carcass removal device.
