  • the roll finishing machine 1 in this embodiment includes: the chest 101 as a heating device having a concave curved surface; the chest roll 100 which is a rotating roll that rotates to convey a washed object 2 loaded from the inlet side end 101a of the concave curved surface while pressing and abutting the washed object 2 against the concave curved surface, and discharge the washed object 2 from the outlet side end 101b of the concave curved surface; and the suction peeling device (103a, 104, 104a, 106) that peels the washed object 2, which is discharged from the outlet side end 101b of the concave curved surface, off the chest roll 100.
  • the chest 101 as a heating device having a concave curved surface
  • the chest roll 100 which is a rotating roll that rotates to convey a washed object 2 loaded from the inlet side end 101a of the concave curved surface while pressing and abutting the washed object 2 against the concave curved surface, and discharge the was
  • the suction peeling device (103a, 104, 104a, 106) has: the suction surface 110 having a plurality of openings 111, the suction surface 110 sucking and peeling the washed object 2 off the chest roll 100; the exhaust device 104 that causes air to be sucked from the plurality of openings 111; and the ventilated conveying belt 106 that travels the suction surface 110 and conveys the washed object 2 peeled off the chest roll 100.
  • the suction surface 110 has the vertical surface 110a as a planar part facing to the roll surface of the chest roll 100 at a position in the vicinity of the outlet side end 101b of the concave curved surface, the position being located in a direction of an extension of the concave curved surface from the outlet side end 101b.
  • the vertical surface 110a is a planar part facing to the roll surface of the chest roll 100 at a position in a direction of an extension of the concave curved surface from the outlet side end 101b, contrary to a conventional curved surface, an increase in a distance between the washed object 2 and the suction surface 110 can be reduced after the washed object 2 leaves the chest 101 from the outlet side end 101b. As a result, a deterioration in the suction effect of the suction peeling device can be reduced so that the washed object 2 can be reliably peeled off the chest roll 100.
  • the planar part of the suction surface 110 is the vertical surface.
  • This configuration is employed because the direction of the extension of the concave curved surface from the outlet side end 101b generally corresponds to the vertical plane direction if the outlet side end 101b of the chest 101 is in the vicinity of the horizontal plane 100j passing through the center of the shaft of the chest roll as illustrated in Fig. 4 .
  • the planar part is preferably the vertical surface which extends in the vertical plane direction.
  • the planar part may be a planar surface extending in the inclined direction or may be a vertical surface.
  • the suction surface 110 has a convex curved surface 110b that extends away from the roll surface, the convex curved surface 110b being contiguous to the end of the vertical surface 110a which is the planar part in a direction in which the washed object 2 is conveyed.
  • the vertical surface 110a of the suction surface 110 is configured to extend generally in a vertical direction. With this configuration, the washed object 2 peeled off the roll surface can be effectively placed on the delivery belt 106.
  • the roll finishing machine further includes: the calender roll 202 as a heating roll that is rotatable; the conveying belt 204 as a traveling belt that is wound around a part of a circumferential surface of the calender roll 202 and travels following the rotation of the calender roll 202, the conveying belt 204 pressing the washed object 2 that has been peeled off the chest roll 100 against the calender roll 202 while the washed object 2 is held between the conveying belt 204 and the calender roll 202; the scraper 102 that scrapes a stuck object sticking to the surface of the chest roll 100; the operation unit 40 that outputs a deactivation command and an activation command for the exhaust device 104, in accordance with the operator's operation; and the control unit 50 that deactivates an operation of the exhaust device 104 in accordance with the deactivation command from the operation unit 40 and activates the operation of the exhaust device 104 in accordance with the activation command from the operation unit, wherein: when the operation unit 40 outputs
  • the suction by the exhaust device 104 is deactivated in response to the deactivation command outputted from the operation unit 40 to the control unit 50 in response to the operator's operation.
  • the wax cloth 3 remains stuck to the chest roll 100 and moves toward the inlet side end 101a, following the rotation of the chest roll 100. Then, the wax cloth 3 moving toward the inlet side end 101a is scraped off by the scraper 102. As a result, it can be prevented that the wax cloth 3 passes through the calender roll finishing unit 20 in a subsequent stage.
  • the scraper 102 may be movable between the contact position B2, which is a first position at which the scraper 102 is in contact with the roll surface of the chest roll 100, and the retracted position B1, which is a second position at which the scraper 102 is separated from the roll surface, wherein: the scraper 102 may be moved to the contact position B2 in response to the deactivation command and moved to the retracted position B1 in response to the activation command.
  • the scraper 102 is in contact with the chest roll 100 only when the wax cloth 3 is loaded into the roll finishing machine 1, which can mitigate the scratching of the roll surface by the scraper 102.
  • the washed object 2 peeled off by the suction peeling device is conveyed to the calender roll finishing unit 20, which is a subsequent processing device, and the washed object 2 is then loaded into the calender roll finishing unit 20.
  • the delivery belt 106 may also be responsible for conveying the washed object 2 from the chest roll 100 to the calender roll 202, which can result in a simplification of the conveying system and a reduction in cost.
  • the roll finishing machine includes: the chest 101 as a heating device having a concave curved surface; the chest roll 100 which is a rotating roll that rotates to convey a washed object 2 loaded from the inlet side end 101a of the concave curved surface while pressing and abutting the washed object 2 against the concave curved surface, and discharge the washed object 2 from the outlet side end 101b of the concave curved surface; the calender roll 202 as a heating roll that is rotatable; the conveying belt 204 that is wound around a part of a circumferential surface of the calender roll 202 and travels following the rotation of the calender roll 202, the conveying belt 204 pressing the washed object 2 against the calender roll 202 while the washed object 2 is held between the conveying belt 204 and the calender roll 202; and the suction peeling device (103a, 104, 104a, 106) that peels the washed object 2, which is
  • the suction peeling device (103a, 104, 104a, 106) has: the suction surface 110 having a plurality of openings 111, the suction surface 110 sucking and peeling the washed object 2 off the chest roll 100; the exhaust device 104 that causes air to be sucked from the plurality of openings 111; the delivery belt 106 as a ventilated conveying belt that travels on the suction surface 110 and conveys the washed object 2 peeled off the chest roll 100 to a washed object inlet (located directly before a position at which the calender roll 202 and the conveying belt 204 contact each other in Fig. 1 ) of the calender roll 202.
  • the delivery belt 106 is also responsible for conveying the washed object 2 from the chest roll 100 to the calender roll 202. As a result, a simplification of the conveying system and a reduction in cost can be achieved.
  • the chest roll finishing unit 10 having a single chest roll 100 has been described as an example in the above-described embodiment, the chest roll finishing unit 10 may be provided with a plurality of chest rolls 100. However, if there are a plurality of chest rolls 100, a delivery mechanism is required to deliver the washed object 2 between the chest rolls 100. By contrast, if the chest roll 100 having a large diameter greater than 1000 [mm] is used as described above, the single chest roll 100 can perform a roll finishing process comparable to the roll finishing process in the case where the plurality of chest rolls 100 are provided, wherein the above-described delivery mechanism required for the plurality of chest rolls 100 is eliminated. Thus, a simplification of the device configuration and a reduction in an installation area of the chest roll finishing unit 10 can be achieved.
