Meanwhile, from this stage (after the moment that can contact with coated portion 7 at Porous sorption pad 27), above-mentioned main vacuum pump is in opening.Thus, the coated portion 7 of the electrode foil 6U of most top layer is attracted by Porous sorption pad 27.But carve at this moment, substrate parts 26 grade still maintains the state of moving downward.
Then, servomotor 24 with formerly contrary rotation and action, thus, as shown in Fig. 6 (d), upward movement such as substrate parts 26 grade.Thus, attracted by Porous sorption pad 27 in coated portion 7, and under the state that is attracted at Porous sorption pad 36 of uncoated portion 8, lift on the electrode foil 6 of most top layer.In addition, from the compressed-air actuated injection of air-blast nozzle 42, continue to carry out during lifting on temporarily.Thus, even if when being close between contingency coated portion 7, both can more positively be separated.In addition, if by means of only the attraction of coated portion 7, electrode foil 6 does not fall, then obviously carve at this moment, can remove the attraction in uncoated portion 8.
In addition, under the state that at least coated portion 7 is attracted by Porous sorption pad 27, the actions such as above-mentioned not shown electrical motor, along not shown guide rail, substrate parts 26 grade with electrode foil 6, and moves in the horizontal direction.Then, when arriving above electrode foil supply unit 12, again making servomotor 24 action, substrate parts 26 etc. is moved downward.Then, main vacuum pump (with secondary vacuum pump) is closed condition, removes the attraction of electrode foil 6.Thus, an electrode foil 6 is supplied in electrode foil supply unit 12.After this supply completes, make servomotor 24 action again, make rising such as substrate parts 26 grade, in addition, moved to the position in above-mentioned pedestal portion 18.
By repeatedly carrying out above-mentioned action, in electrode foil supply unit 12, repeatedly supply an electrode foil 6.In addition, this electrode foil feed mechanism 21 corresponds respectively to anode foil 1 and cathode foil 3 and arranges, according to anode foil 1 and cathode foil 3 sequence alternate be supplied in electrode foil supply unit 12.
As above-mentioned specific descriptions, according to this form of implementation, for the electrode foil 6 be stacked and placed in pedestal portion 18, the mode being positioned at phase the same side according to uncoated portion 8 is completely stacked.Due to the thickness of relative coated portion 7, the thickness in uncoated portion 8 is less thickness to a great extent, if therefore under the stacked state of electrode foil 6, when there is the possibility be close between coated portion 7, easily between uncoated portion 8, form gap, be difficult to generation and be close to.For this point, in this form of implementation, never side, coated portion 8, lifts first preferentially.More particularly, first by multistage bellows sorption pad 36, the uncoated portion 8 of the electrode foil 6 of the most top layer of sorption, makes it rise.With this situation, the ora terminalis of coated portion 7 of the electrode foil 6 (6U) of most top layer is separated with the ora terminalis of the coated portion 7 of the electrode foil 6 (6L) of positive lower floor, then makes electrode foil 6 rise overally.
In addition, now, while above-mentioned uncoated portion 8 lifts, the never air-blast nozzle 42 of side, coated portion 8, sprays pressurized air.Thus, the ora terminalis of the coated portion 7 of the electrode foil 6 (6U) of most top layer is separated more easily from the ora terminalis of the coated portion 7 of the electrode foil 6 (6L) of its positive lower floor.In this form of implementation, their two actions (attraction in uncoated portion 8, on lift brush with air) interact, the ora terminalis of the coated portion 7 of the electrode foil 6 (6U) of most top layer is separated relative to the ora terminalis of the coated portion 7 of the electrode foil 6 (6L) of its positive lower floor, so the most electrode foil 6 (6U) of top layer is separated with the electrode foil 6 (6L) of its positive lower floor.Thus, more positively only can lift on the electrode foil 6 (6U) of most top layer, consequently, can more positively prevent from once, lifting multiple this fault of electrode foil 6.
In addition, in this form of implementation, the multistage bellows sorption pad 36 for sorption uncoated portion 8 can tilt along the vertical direction.As mentioned above, time stacked according to the mode being all positioned at phase the same side in uncoated portion 8, due to the thickness of relative coated portion 7, the thickness in uncoated portion 8 is less, therefore uncoated portion 8 is stacked under the state that inclination is sagging on the whole.In this regard, even if such as when the uncoated portion 8 of the electrode foil 6 (6U) of most top layer tilts sagging, along with this sagging multistage bellows sorption pad 36 also can tilt, can more positively sorption uncoated portion 8.So, more positively can avoid sorption uncoated portion 8 and damage this fault.
Further, in this form of implementation, multistage bellows sorption pad 27 is arranged on substrate parts 26, and this substrate parts 26 relatively, be integrally formed into above-mentioned driving cylinder 32 etc.Thus, driving cylinder 32, multistage bellows sorption pad 36, while substrate parts 26 up-and-down movement with servomotor 24 action, can up-and-down movement.Thus, when being in the upward movement etc. of the electrode foil 6 (6U) of the above-mentioned most top layer of sorption state because of Porous sorption pad 27, do not make action such as driving cylinder 32 grade, electrode foil 6 (6U) corresponds to above-mentioned upward movement etc. with uncoated portion 8, moves.In this sense, the simplification of device entirety can be sought.
