To rotate. As the tire (1) rotates, the lubricant contained in the sponges (12) (12) ... Is applied to the bead portion (1a). When the tire (1) rotates about one and a half revolutions, the rotary drive motor (14) is stopped, the sponges (12) (12) ... are folded, and then the lift table (15) is raised. Support the tire (1). Next, the rotating rollers (10), (10), (11) and (11) are released to the outside to release the tire (1), and the lift table (15) is lowered to move the tire (1) onto the belt conveyor (4). Back to the transport conveyor (2).

[0013]

[Problems to be solved by the device]

 The lubricant application device presses the sponge (12) (12) containing the lubricant against the bead portion (1a) of the tire (1), and in this state, the tire (1) is rotated to apply the lubricant. Therefore, the rotating rollers (10), (10), (11) and (11) for gripping and rotating the tire (1) and the rotating mechanism for gripping and rotating these with respect to the tire (1). (6) is required, and a coating mechanism (7) for inserting and expanding the sponge (12) (12) ... into the tire (1) is required. Further, the tire (1) is attached to the belt conveyor (4). A lift mechanism (5) for floating from above was also required, and the structure was complicated.

Further, during the coating operation, the lubricant is scattered from the sponges (12) (12) ... to the surrounding rotating rollers (10) (10), (11) (11) and the rotating mechanism (6). In some cases, adhesion and rust and the like occurred, resulting in malfunction, or dripping downward and hitting the lift mechanism (5), and the lift mechanism (5) caused malfunction due to rust and the like.

This invention intends to provide a lubricant applying device which simplifies the structure of the device and eliminates the mechanical portion so as not to be adversely affected by the lubricant.

[0016]

[Means for Solving the Problems]

 This invention is to apply a lubricant, and to apply a large number of brushes to the inside of the bead portion of the tire on the periphery of the rotating member, and a lifting means for raising and lowering the applying brush with respect to the tire. And a rotating means for rotating the coating brush.

[0017]

With the above lubricant applying device, the brush for application is lowered without moving the tire, the brush brushed on the brush for application is inserted inside the bead portion of the tire, and the brush for application is rotated. , Apply lubricant. Then, the brush spreads outward due to the centrifugal force due to the rotation and is pressed against the bead portion of the tire, and the lubricant is applied.

[0018]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, in the lubricant applying device, brushes (61) are dispersed around the lower surface of the rotating member (60) around the entire circumference or at a plurality of places (for example, four places) to be transplanted. In addition, the application brush (62) is rotated to apply the lubricant. The brush (61) is arranged to have a diameter smaller than the inner diameter of the bead portion (1a) of the tire (1).

The rotating member (60) is rotatably supported by a rotating means (rotating cylinder) (64) via a rotating shaft (63), and the rotating cylinder (64) conveys a tire (1) with a conveyor (2). ) A lifting frame (elevating cylinder) (66) attached to a supporting frame (65) installed above the upper and lower parts raises and lowers. Further, guide rods (67) (67) are provided on both sides of the lifting cylinder (66) so as to be able to move up and down, and the guide cylinders (67) (67) guide the rotating cylinder (64) to move horizontally. There is.

In the lubricant applying device, when the tire (1) conveyed by the conveyer conveyor (2) is stopped below the coating brush (62) which has been waiting above, the lift cylinder (66) is moved. The brush (61) is extended into the tire (1) by lowering the coating brush (62). After the insertion, the rotary cylinder (64) is operated to reciprocally rotate the coating brush (62) at a predetermined angle (for example, 180 degrees), and the lubricant applied to the brush (61) is applied to the bead portion () of the tire (1). Apply to 1a).

In the lubricant applying device, when the applying brush (62) is rotated, the brush (61) provided on the rotating member (60) spreads outward due to its centrifugal force, and the bead portion of the tire (1). Since it is automatically pressed against (1a), the lubricant can be reliably applied without pressing the brush (61) against the bead portion (1a) of the tire (1) in advance. Further, since the brush (61) automatically follows the bead portion (1a) of the tire (1), it is not necessary to press the application brush (62) onto the bead portion (1a) of the tire (1), and the application brush It is not necessary to center the (62) and the tire (1) accurately.

The coating brush (62) may be rotated several times in a fixed direction when the lubricant is applied.

[0024]

[Effect of device]

 According to this invention, the tire is fixed, and the brush provided on the application brush is inserted into the tire and rotated to apply the lubricant, so that the lift mechanism for lifting the tire and holding the tire are held. A rotating mechanism for rotating the brush is unnecessary, and since the brush is automatically pressed against the bead of the tire by centrifugal force to perform the coating work, a mechanism for accurately centering the tire and pressing the brush against the tire are applied. No mechanism is required, and the device is very simple.

In addition, there is no mechanical part around or under the coating brush, and the lubricant is not attached to the coating brush, so that it is not affected by rust or the like.
