る。2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, JP-A-62-859 is used to cool an ink roller of a printing machine.
The one described in Japanese Patent Publication No. 46 has been proposed. In this conventional example, the ink roller 1 is a roller tube 3 made of aluminum, and a roller holder 1 for holding both ends of the roller tube 3.
0 and 11, the cooling medium (temperature adjusting medium) is supplied and discharged from the end surface of one roller holder 10. A plurality of passages 2 are arranged near the pipe wall of the cross section of the roller pipe 3, and a pair of the passages 2 are provided among the plurality of passages 2.
(2a, 2b) are connected to each other by a notch groove 7 provided in the end surface of the other roller holder 11. By this connection, the cooling medium is transferred from the outward passage 5 to the passage 2a and the notch groove 7
And the flow path 2b to the return path 6, and reciprocates once in the axial direction of the roller tube 3 to uniformly cool the outer peripheral surface of the roller tube 3. The cooling medium, such as cooling water, is fed from the supply side of the rotary joint 15 to the inner diameter 17 of the roller holder 10.
It flows through the pipe 16 provided at the center of the inside to the outward passage 5, and also passes from the return passage 6 through the passage 18 between the pipe 6 and the inner diameter 17 to the discharge side of the rotary joint 15.

There is a thing shown in FIG. 6 as what is supplied and discharged from. In this example, the cooling water is fed from the supply side of the rotary joint 15 to the forward passage 12 in the pipe 16 provided in the center of the inner diameter 17 of the roller holder and the inner passage 1 of the roller pipe 3.
3, a plurality of holes 14 radially opened from the end of the inner passage 13 on the roller holder 11 side so as to communicate with the inner passage 2 of the roller pipe 3, the passage 2 and the return passage 6, and the outer peripheral side of the pipe 16. A return water flow system is adopted in which the flow passes through the passage 18 to the discharge side of the rotary joint 15.

As described above, there is one that adopts the one-way water flow system in which the other rotary joint 19b (single type) discharges the water. In all of the conventional examples described above, the cooling medium cools the outer peripheral surface of the ink roller 1 by the flow in a single direction, but in these water-passing methods, the axial direction (flow direction) of the ink roller 1 is used. A temperature gradient occurs in the cooling water, and the outer peripheral surface of the ink roller 1 is not cooled uniformly. Therefore, when a plurality of ink rollers 1 are installed, the supply and discharge directions of the cooling water to the respective ink rollers are alternately changed, and the ink supplied through the plurality of ink rollers is transferred to the roller tube. It is designed to be uniformly cooled in the axial direction.

法及び装置を提供しようとするものである。When a plurality of cooling rollers are provided by causing cooling water to flow near the wall of the roller tube of the cooling roller as in the above-mentioned conventional example (generally this case is common). ) Is a return water flow system and a one-way water flow system, in which the direction of supplying and draining the cooling water is alternately changed for each cooling roller, and the roller tube of the ink supplied through the plurality of cooling rollers is changed. Although the cooling in the axial direction is made uniform, the cross-sectional area of the cooling passage is large in any of the above water-passing methods (in the method in which the passage cross-section has a length of 1 in the circumferential direction, the outer circumferential length of the roller pipe is Approximately ½, the return and one-way water flow systems have an approximately outer circumferential length), so the flow velocity of the cooling water in the passage is slow, which causes a temperature gradient and deteriorates the cooling effect. Therefore, in order to increase the flow velocity of the cooling water, it may be possible to reduce the width of the cooling passage in the radial direction to reduce the passage area. However, in this way, the passage becomes flat and the resistance of the cooling water is reduced. It tends to increase and cause turbulence, which is not preferable. The present invention provides a cooling method and apparatus for flowing the cooling medium of the cooling roller, which can increase the flow velocity of the cooling medium with a simple structure, uniformize the cooling in the axial direction of the cooling roller, and increase the cooling efficiency. It is the one we are trying to provide.

Further, the partition plates adjacent to each other in the circumferential direction in order to arrange the plurality of partition plates in a zigzag manner so that the cooling medium flows in a zigzag manner in the circumferential direction of the cooling roller a plurality of times are opposite to each other. The shaft end portion on the side is cut out to form a notch groove that forms a passage, and this serves as a means for solving the problem.

均一になる。The cooling medium flowing in from the outward passage is formed by a plurality of partition plates provided in a zigzag pattern extending in the radial direction between the outer cylinder and the inner cylinder of the cooling roller and extending in the axial direction. Not only can it reciprocate through the cooling roller in the circumferential direction a plurality of times (N times) while reciprocating in the axial direction, but also in the circumferential direction of the passage of the cooling medium provided near the roller tube tube wall. Is about 1 / N of the outer circumferential length of the roller tube, and the passage cross-sectional area can be reduced, and the flow velocity is correspondingly increased. Therefore, depending on the flow rate, if the flow rate is constant, a good cooling effect can be obtained in 2 to 3 reciprocations. Further, since the reciprocation is repeated a plurality of times, the cooling of the roller tube in the axial direction becomes uniform.
