The present invention relates to a roll over can drive apparatus of tire building machine supporting a bladder turning up a green tire semi-finished product on the molding drum when the bladders are expanded in the green tire molding process, and more specifically, to a roll over can of the tire building machine in which an operation cycle time and failure rate are reduced from a simplified structure. For this, the present invention discloses a roll over can drive device of a tire molding machine comprising: a bladder which supplies air to an interior of a various semi-finished products located on a forming drum and turns up the semi-finished products which located on a bead outside, and a roll over can which pushes the bladder to build a green tire, wherein the roll over can rotates on an axis of rotation of a supporting frame by a cylinder, and wherein the cylinder being connected to a support of the roll over can is mounted via a hinge axis to a top of the support frame.


A tire equipped with a sensor patch includes a sensor module and a sensor patch. The sensor patch is formed integrally with the inner liner of the tire by being vulcanized into the inner circumferential surface, and an accommodation space is formed in a region so that the sensor module can be fixed therein. A sensor patch is integrated with the inner liner without damaging the inner liner, and thus the sensor patch can be strongly bound to the tire. Furthermore, since the sensor patch is formed to have a thickness smaller than the thickness of the inner liner, when the sensor patch is vulcanized into the inner liner, the pressure of the bladder being exerted locally non-uniformly on the inner liner can be prevented.

The invention relates to a power transmission device of a green tire forming drum apparatus that includes a carcass drum shaft, left and right forming drums (2a,2b) mounted to the carcass drum shaft in a laterally symmetrical manner and being movable laterally in an axial direction of the carcass drum shaft, finger mounting supports for moving left and right turn-up fingers (3a,3b), respectively mounted to the left and right forming drums, up and down, and a driving unit (5) for supplying power required for rotational and lateral movement of the forming drums and up/down movement of the turn-up fingers. Power generated by a lower servomotor (6c) of the driving unit is transmitted to the forming drums via pull/push plates connected to a ball screw (7a), and power generated by an upper servomotor (6b) of the driving unit is transmitted to the turn-up fingers via pull/push plates connected to another ball screw (7b).

Disclosed is an automatic creel loading apparatus. The automatic creel loading apparatus is configured to unload creels, around which wires for use in manufacturing a tire are wound and which are stacked in multiple layers and multiple rows on a loading pallet, from the loading pallet and to carry and load the creels onto loading shafts of a creel stand, in order to supply the wires to the tire manufacturing process. The apparatus includes a loading base, on which the loading pallet loaded with the creels is disposed, an unmanned transport cart for reciprocatingly moving the loading base along transport rails, and a multi-axis rotational loading robot mounted to the loading base in order to unload the creels from the loading pallet and to carry and load each of the creels onto a corresponding one of the loading shafts of the creel stand.


The disclosed technology generally relates to an installation structure for installing a sensor module, and more particularly relates to an installation structure for installing a sensor module on a tire, and to a method of manufacturing the installation structure. In one aspect, the installation structure includes a sensor module housing configured to accommodate a sensor module and at least one sensor patch each comprising a bonding portion configured to attach to an inner side of a tire and a pressing portion configured to place and maintain the sensor module housing in contact with an installation position on the inner side of the tire. The pressing portion is configured to apply a downward pressure on a top portion of the sensor module housing by elastically extending and contracting.


The present invention relates to a structure for installing a sensor module on a tire and a method of manufacturing the structure. The structure includes: a sensor module housing accommodating the sensor module; and one or more sensor patch having a bonding portion that is attached to the inner side of a tire and a pressing portion that brings and maintains the sensor module housing in close contact with an installation position, in which the pressing portion presses down the top of the sensor module housing by extending and contracting. Accordingly, the structure has the advantage of conveniently mounting and separating a sensor module, being applicable to various sensors and various positions, and improving reliability of mounting the sensor module.

Disclosed is a power transmission device of a green tire forming drum apparatus. The green tire forming drum apparatus includes a carcass drum shaft, left and right forming drums mounted to the carcass drum shaft in a laterally symmetrical manner and being movable laterally in an axial direction of the carcass drum shaft, finger mounting supports for moving left and right turn-up fingers, respectively mounted to the left and right forming drums, up and down, and a driving unit for supplying power required for rotation& and later& movement of the forming drums and up/down movement of the turn-up fingers. Power generated by a lower servomotor of the driving unit is transmitted to the forming drums via pull/push plates connected to a ball screw, and power generated by an upper servomotor of the driving unit is transmitted to the turn-up fingers via pull/push plates connected to another bail screw.


The present invention relates to a tire silent foam fixing structure for attaching a silent foam to a tire, and a manufacture method thereof. In detail, the present invention relates to a tire silent foam fixing structure that includes: a silent foam for reducing noise generated in a tire; and a plurality of silent foam fixing bands made of an extendable material and having an attaching portion fixed to the inner side of the tire and a pressing portion bringing and keeping the silent foam in contact with the inner liner, in which the pressing portion presses down the top of the silent foam by extending and contracting and a specific adhesive layer is not applied. Therefore, it is possible to easily attach the silent foam and to firmly attach the silent foam to the inner side of a tire without damaging the tire.
