(manufacture method of the coated band of pipe)
Below, the manufacture method that uses above-mentioned manufacturing installation 100 to manufacture the coated band of pipe is described.
First, as shown in Figure 2, pipe 13 inner sides to cylinder part 20 (inner circumferential side) are inserted (the 1st inserts operation).Specifically, the mode of protruding from the axial both ends of cylinder part 20 to manage 13 axial both ends, axially the inserting to the inner side of cylinder part 20 along cylinder part 20 by pipe 13.
Then, by the projection 13A protruding from cylinder part 20 in pipe 13 axial both ends to radial outside hole enlargement, this projection 13A is turned back to the outer peripheral face of cylinder part 20.
Then, retainer ring 14,16 is arranged on to the axial both ends of cylinder part 20, pipe 13 is fixed with respect to cylinder part 20.Thus, the space (gap) between the inner peripheral surface of cylinder part 20 and the outer peripheral face of pipe 13 becomes enclosure space.
Then, as shown in Figure 3, the cylinder part 20 that retainer ring 14,16 is installed is arranged on downside installation portion 40.Thus, downside installation portion 40 is close to from downside and retainer ring 16, cylinder part 20(pipe 13) the opening 20B of downside be closed.
Then, to make to become between the inner peripheral surface of cylinder part 20 and the outer peripheral face of pipe 13 mode of the 1st negative pressure (with reference to Fig. 9 " P1 "), air to this space attracts, and makes to manage on the inner peripheral surface that 13 outer peripheral face is adsorbed on cylinder part 20 (absorption process).Specifically, by driving vavuum pump 29, via the attraction path 26,27 at axial both ends that is located at cylinder part 20, attract the air between the inner peripheral surface of cylinder part 20 and the outer peripheral face of pipe 13.Thus, strain is on one side to radial outside expansion on one side for pipe 13, and the outer peripheral face of pipe 13 is adsorbed on the inner peripheral surface of cylinder part 20.
Then, as shown in Figure 4, maintaining under the state of the attraction (driving vavuum pump 29) in above-mentioned absorption process, make to decline at the upside installation portion 30 that utilizes support portion 36 to support under the state of core body 12.Thus, core body 12 and tunicle 10 are attracted to the pipe 13(cylinder part 20 under the state of inner peripheral surface of cylinder part 20 to outer peripheral face) inside insert (the 2nd inserts operation), and, upside installation portion 30 is close to from upside and retainer ring 14, cylinder part 20(pipe 13) the opening 20A of upside be closed.
By upside installation portion 30 and downside installation portion 40 and the retainer ring 14,16 being arranged on cylinder part 20 are close to, as shown in Figure 5, the space between inner peripheral surface and the outer peripheral face of tunicle 10 of pipe 13 becomes enclosure space.
Then, maintaining under the state of attraction in above-mentioned absorption process (driving vavuum pump 29), from the both end sides of cylinder part 20, with make to manage 13 and tunicle 10 between become the mode of the 2nd negative pressure (with reference to Fig. 9 " P2 ") that absolute value is less than or equal to the 1st negative pressure, the air in this space is attracted to (attraction operation).Specifically, by drive vavuum pump 39, via the attraction path 35 of upside installation portion 30 and the attraction path 45 of downside installation portion 40, to manage 13 and tunicle 10 between air attract.Therefore,, in this attraction operation, become in the inner circumferential side of pipe 13 and the outer circumferential side of pipe 13 and carrying out the state (with reference to Fig. 9) attracting.And the attraction in inner circumferential side and the outer circumferential side of this pipe 13 is carried out predetermined time T1(with reference to Fig. 9).Predetermined time T1 is for example made as 20 to 30 seconds.
In addition, the 1st negative pressure (with reference to Fig. 9 " P1 ") and the 2nd negative pressure (with reference to Fig. 9 " P2 ") are all set as the negative pressure that absolute value is more than or equal to 90kPa.In addition, as mentioned above, the 2nd negative pressure is set as the negative pressure that absolute value is less than or equal to the 1st negative pressure.Therefore,, if the 1st negative pressure is for example-95kPa, the 2nd negative pressure is set as that absolute value is more than or equal to 90kPa and the negative pressure that is less than or equal to the scope of 95kPa.In addition,, sometimes attracting in operation, due to the relation of the pressure differential of the 1st negative pressure and the 2nd negative pressure, sometimes manage a part of 13 and be coated to tunicle 10.
Then, as shown in Figure 6, maintaining under the state of the attraction (driving vavuum pump 39) attracting in operation, stop the attraction (driving vavuum pump 29) in absorption process, make to manage 13 to tunicle 10 coated (coated operation).Specifically, maintaining under the state of the attraction (driving vavuum pump 39) attracting in operation, stop the attraction (driving vavuum pump 29) in absorption process, the space between the inner peripheral surface of cylinder part 20 and the outer peripheral face of pipe 13 is to atmosphere opening.Thus, due to pipe 13 elastic force (elasticity recoverys), the internal diameter of pipe 13 dwindles, bonding by managing 13 the adhesive linkage in interior week and the outer peripheral face of tunicle 10, manages 13 and is coated to tunicle 10.
In addition, attract attraction (driving vavuum pump 39) in operation carrying out after predetermined time T2, stopping (with reference to Fig. 9).Predetermined time T2 is for example made as 20 to 30 seconds.Predetermined time T2 can be identical with above-mentioned predetermined time T1, also can be different.
Then, as shown in Figure 7, will be taken out (taking-up operation) from cylinder part 20 by pipe 13 coated tunicle 10 and core bodys 12.Specifically, by making to keep the upside installation portion 30 under the state of core body 12 to rise, managed 13 coated tunicle 10 and core bodys 12 to take out from the opening 20A of the upside of cylinder part 20.In addition, above-mentioned taking-up operation can form in such a way.,, under the state shown in the Fig. 6 stopping after vavuum pump 29 and 39, first remove the support (controlling) of the upper axial end portion of support portion 36 to core body 12.Then, make upside installation portion 30 increase.Then, the cylinder part 20 in inside with core body 12 is pulled down from downside installation portion 40.Now, the outer peripheral face that is supported on the tunicle 10 on the outer peripheral face of core body 12 is bonding with the adhesive linkage in the interior week of pipe 13, and the axial both ends of pipe 13 utilize retainer ring 14 and 16 to be arranged on the axial both ends of cylinder part 20.Then, pull down retainer ring 14 and 16 from the axial both ends of cylinder part 20, will be taken out (taking-up operation) from cylinder part 20 by pipe 13 coated tunicle 10 and core bodys 12.Then, as required, utilize the heating such as heating furnace by pipe 13 coated tunicle 10 and core bodys 12, make to manage 13 further bonding securely with tunicle 10.
Then, as shown in Figure 8, on the core body 12 from cylinder part 20 takes out, tunicle 10 is peeled off to (stripping process).And, will be cut off (with reference to double dot dash line C) by the unwanted part at the axial both ends of the coated tunicle 10 of pipe 13, obtain managing coated band.As mentioned above, produce the coated band of pipe.In addition, the coated band of pipe is for example used as the fixing band in the image processing system of electro photography, as release layer and cage walls.
As mentioned above, in this manufacture method, to manage 13 and tunicle 10 between air attract after, stop the attraction between inner peripheral surface to cylinder part 20 and the outer peripheral face of pipe 13, make to manage 13 and be coated to tunicle 10.Therefore, with not to manage 13 and tunicle 10 between the situation of the manufacture method that attracts of air compared with, can reduce the air capacity remaining between tunicle 10 and pipe 13.
In addition, in this manufacture method, the absolute value of the pressure (the 2nd negative pressure) between pipe 13 and tunicle 10 is less than or equal to the pressure (the 1st pressure) between cylinder part 20 and pipe 13, therefore, can effectively reduce the air remaining between pipe 13 and tunicle 10.; the absolute value of the pressure (the 2nd negative pressure) between pipe 13 and tunicle 10 is greater than the comparative example of the 1st negative pressure; compared with the attraction that pipe 13 is attracted to its outer circumferential side; the attraction attracting to the inner circumferential side of pipe 13 is strong, likely under the state that has large quantity of air between pipe 13 and tunicle 10, causes managing 13 and occurs bonding with tunicle 10.But, in this manufacture method, avoided above-mentioned situation.In addition, from suppress to cause managing 13 and tunicle 10 between closed viewpoint, compare with the situation that the 1st negative pressure is uniform pressure with the 2nd negative pressure, preferably the absolute value of the 2nd negative pressure is less than the 1st negative pressure.
As mentioned above, in the manufacture method of present embodiment, because minimizing remains in the air capacity between tunicle 10 and pipe 13, therefore, the activity duration that remains in the air between tunicle 10 and pipe 13 for extracting out becomes the shorter time.For example, current this activity duration will spend and be more than or equal to 10 hours, but present embodiment can foreshorten to for example 1 to 4 hour.In addition the operation that, remains in tunicle 10 and the air of pipe between 13 for extracting out be coated to be with by disposed tubes to be carried out.
(the 1st variation)
In above-mentioned attraction operation, to manage 13 and tunicle 10 between attract within the shortest time, to become the 2nd negative pressure, but as shown in figure 10, also can until become the 2nd negative pressure gradually (periodically) to manage 13 and tunicle 10 between attract.Specifically, drive by output less beginning the compared with maximum output that makes vavuum pump 39, until become the 2nd negative pressure gradually to manage 13 and tunicle 10 between attract.In addition, as additive method, can make vavuum pump be output as maximum output, adjustment valve is set connecting on the pipe arrangement attracting between path 35 and vavuum pump 39, by this adjustment valve until become the 2nd negative pressure gradually to manage 13 and tunicle 10 between attract.Thus, from start to manage 13 and tunicle 10 between space attract until reach the time of the 2nd negative pressure, with from starting the space between cylinder part 20 and pipe 13 to attract until reach longer compared with time of the 1st negative pressure.
As mentioned above, by until become the 2nd negative pressure gradually to manage 13 and tunicle 10 between attract, can effectively reduce remain in pipe 13 and tunicle 10 between air.
(the 2nd variation)
In above-mentioned coated operation, merely stop the attraction (driving vavuum pump 29) in absorption process, but also can weaken by (periodically) gradually the driving force of vavuum pump 29, until stop the driving of vavuum pump 29, thereby make the pressure between the inner peripheral surface of cylinder part 20 and the outer peripheral face of pipe 13 move closer to atmospheric pressure from the 1st negative pressure.
As mentioned above, weaken the driving force of vavuum pump 29 by (periodically) gradually, until stop the driving of vavuum pump 29, thus can effectively reduce the air remaining between pipe 13 and tunicle 10.
(the 3rd variation)
