[0009]
The operation of the configuration shown in FIGS. 1 to 4 will now be described. As shown in FIG. 1, the air supply port 11 is attached to the first frame 14, and the air supply port 11 has a first connection end connected to an air supply hose outside the first frame 14, It has a second connection end that fits into the opening on the air supply side of the air blowing head inside the first frame 14, and has a hollow structure in the middle. Therefore, when temperature-controlled air is supplied from the air supply hose to the first connection end of the air supply port 11, the temperature-controlled air flows from the first connection end of the air supply port 11 to the second connection end, The air is supplied to the opening on the air supply side of the air blowing head.
The air blowing head 1 has a cylindrical shape. One end of the cylinder is an opening on the air supply side, and the other end is closed. A part of the cylinder has a slit-shaped opening parallel to the axis of the cylinder, and this is an opening on the air blowing side. Therefore, the temperature-regulated air sent to the opening on the air supply side is blown out from the opening on the air blowing side. The blown temperature-regulated air is blown to the temperature-regulated object 9 to transfer heat and heat the temperature-regulated object 9.
[0010]
As shown in FIG. 3, the air blowing head 1 and the air supply port 11 are fitted (pressed) at the tapered hole 18, and no special connection means is used to connect them. In the air blowing head 1, a force is applied in the axial direction toward the tapered hole 18 of the air supply port 11, and the air blow head 1 and the air supply port 11 are securely fitted to each other, so that the temperature to be supplied can be increased. The air conditioning does not leak in this area.
The force acting on the air blowing head 1 toward the tapered hole 18 is obtained by a compression spring 6 provided between the second set collar 3 and the second arm 8, as shown in FIG.
That is, the air blowing head 1 penetrates a round hole having an inner diameter slightly larger than the outer diameter of the air blowing head 1 formed in the first and second arms 7 and 8, and is parallel to the axis of the air blowing head 1. Are supported by the first and second arms 7 and 8 so as to be able to move. The compression spring 6 applies a force so that the second set collar 3 and the second arm 8 provided on the air blowing head 1 and fixed at a predetermined position are pushed open. Therefore, a force that moves the air blowing head 1 in the direction in which the second set collar 3 moves away from the second arm 8 acts.
[0011]
The movement of the air blowing head 1 is stopped by the first set collar 2 provided on the air blowing head 1 and fixed at a predetermined position abutting on the side surface of the first arm. Is restricted from moving.
The first and second set collars 2 and 3 have a mechanism for adjusting their positions in the air blowing head 1. When the first fixing screw 19 is loosened, the first set collar can move on the air blowing head 1 in a direction parallel to its axis, and after adjusting to an appropriate position, tighten the first fixing screw 19. Thus, the first set collar can be fixed on the air blowing head 1. When the second fixing screw 20 is loosened, the second set collar can move on the air blowing head 1 in a direction parallel to its axis, and after being adjusted to an appropriate position, the second fixing screw 20 can be moved. To fix the second set collar on the air blowing head 1.
[0012]
By adjusting the position of the first set collar 2, it is possible to prevent the air blowing head 1 and the air supply port 11 from fitting together with an excessive force, and prevent the air blowing head 1 from being damaged or easily pulled out. Further, it is possible to prevent the air blowing head 1 from falling off from the first and second arms 7 and 8. Further, by adjusting the position of the second set collar 3, the force acting on the air blowing head 1 by the compression spring 6 can be adjusted.
As described above, the force of the compression spring 6 acts on the tapered hole 18 or the force of the compression spring 6 limited by the first set collar 2 acts on the air blowing head 1 and the air supply port 11 so that they are fitted. I do.
[0013]
The air blowing head 1 is configured to be movable in a direction parallel to the axis and rotatable around the axis. As shown in FIG. 4, the air blowing head 1 is fixed to the second arm 8 in a semi-fixed state by a ball plunger 10, and does not normally rotate, but rotates more than a predetermined amount by hand or the like. When a force is applied, it can be rotated.
The air blowing head 1 has a slit-shaped opening on the air blowing side provided in a direction parallel to the axis, so that the direction of the temperature-controlled air blown out from this opening by rotation can be appropriately adjusted. .
The air blowing head 1 is fitted to the air supply port 11 at the tapered hole 18, and the air blowing head 1 is held by the frictional force at the tapered hole 18. Therefore, even when the ball plunger 10 is not provided, rotation or the like does not occur due to external force due to normal vibration or the like.
[0014]
As shown in FIG. 1, the first and second arms 7, 8 are fixed to each other by a stay 12, and operate as an integrated arm. A hole slightly larger than the outer diameter of the fulcrum shaft 13 is formed in the first and second arms 7, 8 on the opposite side of the portion supporting the air blowing head 1. The fixed fulcrum shaft 13 passes through the hole and rotatably supports the first and second arms 7 and 8.
The side surfaces of the first and second arms 7, 8 are fixed to the fulcrum shaft 13 so that the first and second arms 7, 8 do not move in the direction parallel to the axis of the fulcrum shaft 13. It is abutted and positioned by the collars 4 and 5.
Therefore, the air blowing head 1 is moved in a direction parallel to the axis thereof against the force of the compression spring 6 being negatively biased, and is moved from the tapered hole 18 of the air supply port 11 shown in FIG. When the opening is removed, the first and second arms 7, 8 can rotate around the fulcrum shaft 13.
[0015]
As shown in FIG. 2, the temperature-regulated object 9 can be moved in the direction of the arrow when it is desired to pull it out of the processing machine body for cleaning. It cannot move because of the air blowing head 1. However, when the temperature control is stopped, when the first and second arms 7 and 8 are rotated and moved to the position shown by the two-dot chain line (the retracted position) as described above, the air blowing head 1 is not obstructed and The temperature controller 9 can be moved in the direction of the arrow.
The stopper 16 shown in FIG. 2 restricts the rotation of the first and second arms 7, 8 at the retracted position and stops the rotation, and restricts the rotation of the first and second arms 7, 8 at the operating position to blow air. There is a function of facilitating the alignment for fitting the opening on the air supply side of the head 1 and the tapered hole 18 of the air supply port 11. As shown in FIG. 2, the stopper 16 is provided with an adjusting screw which abuts on the side surface of the arm so that the stop position of the first and second arms 7, 8 in the operating position can be finely adjusted.
[0016]
Although the present invention has been described with reference to the embodiment, the present invention is not limited to this embodiment, and can be applied in various forms based on the technical idea of the present invention. Needless to say,
For example, although an ink fountain has been described as an example of the temperature-controlled object, the present invention is not limited to the ink fountain, and a heating roller, a coating liquid dispenser, a gravure cylinder, or the like can be similarly implemented. It is apparent that the present invention can be applied not only to heating but also to cooling, for example, to a cooling roller, a blast cooling of a heated web, or the like.
