Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a rotary joint device for a rotating shaft.

For example, when molding a molded material using a mold installed on a rotating frame fixed to a horizontal rotating shaft, such as in a molding device for molding the skin of interior decoration layers of automobiles, etc., the temperature inside the mold cavity is controlled by a film. A rotary joint device is known in which a heat transfer fluid is alternately supplied into the mold via a rotary shaft so as to cool the mold during forming and to cool the mold during solidification.

Specifically, conventionally, a rotation joint is provided in the rotation shaft, and the heat medium fluid is supplied and discharged through the rotation shaft. Therefore, the rotating shaft has a double structure, and when the heating/cooling heat medium fluid is exchanged, the supply fluid and the discharge fluid flow in the same rotating joint, which causes a large temperature change of the fluid, which is not good in terms of thermal efficiency. Moreover, it takes time to control the temperature. Furthermore, when there are two or more locations to which fluid is to be supplied, the rotating shaft becomes large and its structure and installation become complicated.

The present invention was made to solve the above-mentioned problems all at once.The purpose of the present invention is to eliminate the need for passing heat medium fluid through the rotating shaft, simplify the structure of the rotating shaft, and The supply and 4: Il output are performed through independent rotating joints, which reduces the change in U degree of the fluid and improves thermal efficiency. Therefore, the seat 11 degree control can be performed efficiently in a short time. In addition to shortening the flexible/pull tubes leading out from the fluid supply and discharge ports on the heat transfer fluid source side, the overall piping length is also shortened, thereby preventing damage to the flexible/pull tubes due to turning. f) 7i1' of the heating fluid due to the piping length.

Next, the operation of the above rotary 7-joint device will be described.

Rotation lll1l]Y is 180° from the state shown in Figure 4
When it rotates, the rotating frame 8 fixed to the rotating shaft 7 and the mounting bracket 12 also rotate together, causing the mounting bracket 12 to rotate.

A tilting motion of 6.6γ is allowed by each rotation of the slider 52.53 (tilt)/mutual rotation of the inner cylinder 62.65 and the outer cylinder 61, 64 of the yoint 60.63. Thus, as shown in FIG. As shown, the positional relationship between the two flexible tubes 68 and 69 is also reversed due to the above-mentioned interlocking structure φ.

The cooled or heated heat medium fluids are then supplied through independent rotating joints (30 and 40), and are simultaneously passed through the same rotating joints as in the past.
Since there is no flow of the output fluid, the temperature change of the heat medium fluid to be supplied is reduced, and the thermal efficiency is improved.
It is possible to efficiently control 11 hours of control in a short time. Historically, there is no need for a heat transfer fluid to pass through the rotating shaft 7, so a 1'11mm (J cylinder) construction of the rotating shaft 7 is sufficient.

In addition, if the number of locations to which fluid needs to be supplied increases, it is possible to extend the mounting bracket 12f in the radial direction and provide a similar piping joint and rotating joint 31-in-1. It is possible to rely on it.

History (・In addition, the guide rails 50, 51-1-: can be moved, and people can rotate and join 1 on the 52 and 53 sides.
-60.63 are provided, and each rotary joint 60.63 is interlocked with each rotary joint (30.40) provided on the mounting bracket 12 through a full-length pipe 66.67, so that the fluid supply of the heating medium fluid source 1111 It is possible to shorten the flexible tubes 68° and 69 extended from the inlet and outlet, and the overall piping length can be shortened accordingly.
Therefore, it is possible to completely prevent damage to the flexible/pull tube due to turning, etc., and improve its durability.
It is possible to suppress a decrease in the temperature of the heating heat medium fluid to be supplied due to the length of the piping. Therefore, in combination with the above effects, the temperature change of the heat medium fluid to be supplied can be minimized, and thermal efficiency and temperature control can be greatly improved.
