積層貼着The present invention relates to a tire attachment/detachment device for a tire molding machine. The molding of radial tires for automobiles involves the primary forming of a cylindrical primary formed tire from a plate-shaped tire carcass;
Deforming the above cylindrical primary molded tire into a toroidal shape,
It consists of secondary forming, in which a belt or tread is endlessly attached to the surface to form a green tire. As a device for taking out the green tire obtained in the secondary molding machine for performing this secondary molding from the molding former that supports the bead part, it is movable in the direction of the main axis of the secondary molding machine. The outer circumferential surface of the green tire is held on the inner surface of a transfer ring that is provided so that its diameter can be expanded and contracted, and the green tire is removed from the molding former by moving the transfer ring in the direction of the main axis. Next, the bead part of the green tire is held by a chuck device, and the outer peripheral surface of the green tire is released from the transfer ring L, and then the chuck device is moved around the horizontal axis by 9 L.
Rotate 0 degrees to change the attitude of the green tire from upright to horizontal, and stop the chuck device 1. Furthermore, the outer peripheral surface of the green tire is gripped by the gripping device, and the bead portion is released from the chuck device 1- 7. After that, it is known that the above-mentioned gripping device is rotated by the upper neck of a conveyor for conveying green tires so that the green tires are dropped (Kame 1 "Open and Close Publication No. 56-104046). However, the above-mentioned known tire take-out device sequentially transfers the green tire supported by the forming former to the transfer ring, the chuck device, and the gripping device, and the number of transfers is large. l') The structure was complicated and failures were likely to occur.Furthermore, the above-mentioned gripping device was formed to grip a toroidal resin tire, and the gripping device was designed to grip a toroidal-shaped tire. Since it is not a device to be gripped, manual work was required to attach the primary formed tire to the forming former. It can be done automatically,
The fNJ f, which combines a molding former and a conveyor, provides a tire attachment/detachment device for a tire molding machine that does not require changing tires and is easy to draw. That is, this invention provides an upper sliding frame that is slidably provided above the tire molding machine parallel to its main axis, an elevating frame that is provided on the upper sliding frame so as to be movable up and down, and a lower end of the elevating frame. a main body frame rotatably connected to the main body frame via a vertical axis around the main body frame, a pivot bracket rotatably connected to the main body frame via a horizontal axis around the main body frame, and a pivot bracket attached to the pivot bracket. This is a tire attachment/detachment device for a tire molding machine that includes a tire clamping mechanism configured to clamp the outer periphery of the tire.
