Definitions

  • This invention is broadly concerned with inking rollers in a printing machine or several rollers in a machine for processing plastic films and intended particularly to be used to a heating or cooling roller (referred to as a thermal roller in the following description ) being in control of its surface temper ature by being heated or cooled.
  • a heating or cooling roller referred to as a thermal roller in the following description
  • Rollers rotating in contact with others are generally employed in several machinery. Taking for an instance, there are arranged several inking rollers between an ink reservoir and a plate cylinder in the printing machine to feed ink to plates which are attached to the plate cylinder by transmitting ink sequentially from one roller to the other contiguous roller. These rollers are apt to go up the temperature of ink on the surface thereof due to a rolling friction heat generated by rotate in contact with others. But, according to specifications of ink, several conditions such as an admirable temperature and range of temperature in use of ink are prescribed. The preferable temperature of ink in offset press is generally recommended to be about 28 degrees. It is then noted that the surface temperature of the inking roller being out of the mentioned conditions for ink becomes a main cause to spoil quality of printed papers. It is also observed in a case of low room temperature in a cold district that the printing machine should be idled until the temperature of ink reaches to the admirable one for the start of daily work, which causes a drop in productivity.
  • HEI 3-21453 issued on January 30th in 1991 proposes a method of controlling the temperature of ink on the plate attached to a plate cylinder, wherein a fluid medium is circulated in the plate cylinder to control the temperature of ink by regulating the fluid medium.
  • a thermal roller employing a fluid medium should be closed up tightly and produced precisely.
  • a conventional device essentially needs a water or heated water circulatory device and a refrigerator, which is undesirable in view of the space.
  • heat pipe are coupled into a roller body from its one end so as to extend partly, so that a components to heat or cool the roller can be minimized. Furthermore, since a thermal transmissible member can be filled in to, so that maintenance become easy.
  • a roller to be heated or cooled has a solid roller body having a hole provided from at least one end along a central axis thereof and one or more heat pipes coupled into one or more holes of the roller body to partly extend therefrom.
  • the heat pipe extended from the roller body is first heated and the applied heat is transmitted to the roller body. While, cooling the roller, unnecessary heat is released from the heat pipe. If fins are provided on the heat pipe extended from the roller body, thermal transmission will be accelerated to facilitate preferable thermal control.

  • the radiation section 12 of the heat pipe 10 has thereon a radiation device 13 including plural fins.
  • the heat pipe 10 contains a working fluid such as water or fleon after decompressing the inside pressure.
  • the contained working fluid is once vaporized at the heat-inlet section 11 by heat and then moved to the radiation section 12 to be condensed.
  • the thus condensed working fluid is returned to the heat-inlet section 11 so that a heat transfer from the heat-inlet section 11 to the radiation section 12 is effected to thereby cool the roller.

  • the radiation device 13 is defined by fins 13b each having a four-sided figure shape.
  • the plural fins 13b are radially secured to the heat pipe 10.
  • Figure 4 shows an modification to compulsorily cool by air.
  • the radiation section 12 and the radiation device 13 of the heat pipe 10 are accommodated in a case 14, all together.

  • the outlet 16 can be connected with a blower 18 to exhaust the used air via a piping 17.
  • the evaporated working fluid in the radiation section 12 of the heat pipe can be condensed and liquefied by radiating the latent heat of condensation from the radiation device 13 to the inside space of the case 14. It will be apparent that the thus radiated heat in the case 14 is exhausted by the blower 18.
  • Figure 5 shows another embodiment of the roller according to this invention.
  • the shown composition is characterized to have therein two of independent heat pipes 101 and 102 which are adapted to be received in a through hole by being inserted from the ends of the roller, respectively.
  • Radiation sections 111, 112 of the heat pipes projected from the ends of the roller are provided with the radiation device 13 including plural fins.
  • the vaporized working fluid will be cooled faster as a circulation distance, from one portion where the working fluid is cooled to the other portion where the working fluid is heated, is shortened.
  • the roller can be cooled separately to thereby suppress the temperature gradient on the roller surface compared with a roller using a single heat pipe.
  • roller 30 is characterized to have a hollow portion in its body and receive plural heat pipes inside.
