On rotation limitation cam 55, the groove portion 56 of the U-shaped shape formed in the way of removing its rising wood is in circumferential direction with 72 ° of interval And it is set to 5 positions.

Corresponding to this, rotation limitation protrusion 57 is formed on the circumferential surface of axle portion 40, which limits protrusion 57 can be towards diameter It protrudes outward, and is inserted into respect to groove portion 56.But rotation limitation protrusion 57 is provided only in circumferential 1 of axle portion 40 A position.In addition, rotation limitation protrusion 57 is inserted into any one of the groove portion 56 at 5 positions, claw 42 is in and stops at as a result, State on any one of stop position X1~X5.

In addition, in axle portion 40, in the lower position of supporting part 50, setting is from its circumferential direction, and shape prominent in radial outside At flange part 60.Between below the flange part 60 and supporting part 50, helical spring 61 is installed.It with this solution, can be by axis Portion 40 is depressed into lower section, and laminated body 4 is pressed by claw 42.

On the other hand, the action cam 63 cylindric in the setting of the lower position of axle portion 40.More specifically, cam is acted 63 are set to the lower position of turntable 6, according to can be by driving mechanism not shown in the figure, being revolved by axle center of upper and lower directions Turn, and mode moving up and down is constituted.But action cam 63 and its driving mechanism are set in addition to without requiring holding The only stacking operation position R2~R9 of the displacement action of component 31 being taken into other than job position R1 and blank position R10, R12 At taking-up job position R11.

In addition, in the turntable 6 of the lower position of axle portion 40, correspond to action cam 63, in jack not shown in the figure It is formed through along the vertical direction.Action cam 63 can haunt on turntable 6 as a result, can impart power to axle portion 40.

In addition, an example of driving mechanism as drive actions cam 63 and enumerate following structures, wherein be used for The fluid hydraulic drive cylinder (driving upside down mechanism) for making the straight line motion that action cam 63 moves up and down, for making action cam The combinations such as the rotation driving cylinder (rotary drive mechanism) of 63 rotations.Obviously, the driving mechanism of holding member 31 (action cam 63) Structure it is without being limited thereto, other driving mechanisms also can be used.

In addition, a pair of cams face 64 is arranged on the top of action cam 63, this is to cam surface 64 according to removing its rising wood Mode formed.This is to cam surface 64 in the position that clamping faces the axle center of cam surface 64, that is, between circumferential direction is with 180 ° Every and formed at interval.

Cam surface 64 is respectively formed in the range of 72 ° circumferential of the central angle of action cam 63, and in along defined 1 A direction of rotation is (for example, in the occasion of holding member 31A, to be clockwise in the occasion of holding member 51D counterclockwise Direction) inclined slope shape from the top down.

Corresponding to this, a pair of of action pin 65 of setting in the lower end of axle portion 40, this can be towards radial outside to action pin 65 And protrude, and can be abutted with the cam surface 64 of action cam 63.This faces action pin 65 in the axle center of clamping axle portion 40 Position, that is, formed at interval with 180 ° of interval in circumferential direction.

Further more, in the present embodiment, claw 42 is the structure that can be subjected to displacement in upper and lower directions with respect to axle portion 40. In the following, specifically the structure is described.In base portion 41, formed make that axle portion 40 passes through in jack not shown in the figure. The internal diameter of the jack and the outer diameter of axle portion 40 are essentially identical.Base portion 41 is in and can along the vertical direction be sent out with respect to axle portion 40 as a result, The state of raw slide displacement.

But base portion 41 is in the state that cannot be subjected to displacement with respect to the circumferential direction of axle portion 40.More specifically, in axle portion On 40 upper periphery face, keyway not shown in the figure is formed in along its axial (upper and lower directions).Corresponding to this, in base portion 41 On the inner peripheral surface of (jack), formation protruded towards its radially inner side, and along the vertical direction and formed be not shown in figure Key.In addition, the key of 41 side of base portion is in the state in the keyway of 40 side of embedded axle portion, base portion 41 (claw 42) is in as a result, Can be axial with respect to it and be subjected to displacement with respect to axle portion 40, and can be circumferential with respect to it and the state that cannot be subjected to displacement.

In addition, in axle portion 40, in the top position of rotation limitation protrusion 57, setting is prominent from its circumferential surface and is formed in diameter Flange part 67 outward.Between below the flange part 67 and base portion 41, helical spring 68 is installed.Pass through helical spring 68 Bias force, base portion 41 and claw 42 are in the state above pushed away upward.Helical spring 68 constitutes the biasing mechanism of present embodiment.

But the upper end of the keyway in 40 side of axle portion, setting limit base in retainer not shown in the figure, the retainer The movement of the key of 41 side of portion.As a result, in general, base portion 41 is in through the bias force of helical spring 68, relatively above-mentioned retainer and The state of biasing.That is, by the bias force of above-mentioned helical spring 61, axle portion 40 is pushed downwards, is pressed by claw 42 When laminated body 4, base portion 41 is in the state being offset on the retainer.

Referring to Figure 10~Figure 15, the correlation specifically acted according to the transport of the sheet body with suction portion 17, to protecting The action for holding the driving mechanism of component 31 illustrates.

It is rotated intermittently in turntable 6, stacked platform S stopped at stacking operation position R2~R9 originally, at holding member 31 In halted state.

(each claw 42 stops at the phase at the places any one of stop position X1~X5 in the halted state of holding member 31 Between), action cam 63 stops at the reference position of the lower section of turntable 6.In the state, in the biasing by helical spring 61 Axle portion 40 is depressed into the state of lower section by power.It is in as a result, and lamination is pressed by the claw 42 for stopping at the 1st stop position X1 The state of body 4.In the example shown in Fig. 10, the cathode claw 42A for stopping at the 1st stop position X1 is in pressing laminated body 4 The state of (anode foil 1).

Then, if by suction portion 17, new sheet body is transported to the top position of stacked platform S, then acts cam 63 It rises near the lower end of axle portion 40, is waited for (referring to Fig.1 0).

Then, suction portion 17 declines, and new sheet body is loaded into the upper surface of laminated body 4 (referring to Fig.1 1).Herein, it is inhaling The foreign side of the peripheral part of socket part 17 and the edge part of sheet body exposed is on the claw 42 for being loaded into the upper surface of pressing laminated body 4 State.In addition, the jack for the margining tablet 38 (limitation protrusion 39) being set on suction portion 17 is inserted on the top in axle portion 40 State in 39a.

If sheet body is loaded into the upper surface of laminated body 4, acts cam 63 and begin to ramp up.Then, if action cam 63 (cam surface 63) is abutted with the action pin 65 of axle portion 40, then is above pushed away axle portion 40 by acting cam 63.

Claw 42 shifts to top as a result, and in the 1st stop position X1, claw 42 leaves with laminated body 4, loads thereon The edge part of sheet body is in the state of upper lift.But it due to rising beginning originally, maintains rotation limitation protrusion 57 to be inserted into and rotates The state of the inside of the groove portion 56 of cam 55 is limited, axle portion 40 does not rotate, therefore the position of the direction of rotation of each claw 42 does not become Change.

In addition, if axle portion 40 above pushed away, axle portion 40 passes through the jack 39a of margining tablet 38 (limitation protrusion 39), and Claw 42 (base portion 41) is abutted with the lower end of limitation protrusion 39.

If from here, axle portion 40 further above pushed away, then pass through margining tablet in the height and position of claw 42 (base portion 41) 38 (limitations protrusions 39) and maintain certain state, resist the bias force of helical spring 68, only above push away axle portion 40.That is, one With axle portion 40 in upper and lower directions relative displacement occurs for side claw 42 (base portion 41), on one side by acting cam 63 only by axle portion Shift scheduled defined height and position on 40 onto.In addition, in the occasion of present embodiment, the axis of rising by acting cam 6 The ascending amount in portion 40 is often certain, does not change.

In addition, as shown in Figure 10, from below suction portion 17 (suction plate 19), that is, the top of laminated body 4 The distance T for the position that lower end, that is, claw 42 (base portion 41) of the position of abutting to margining tablet 38 (limitation protrusion 39) is abutted is Certain.Then, whenever new carrier sheet body, the height and position of claw 42 improves, and still, laminated body 4 is uppermost relatively The ascending amount of claw 42 is often certain.

In addition, the ascending amount of claw 42 according to the ascending amount of axle portion 40, can limit overhang etc. of protrusion 39 and arbitrarily Setting, but in the occasion of present embodiment, since stacked, terminate to stacked, the ascending amount of claw 42 is according to often constant Mode set.

If by defined height and position is shifted in axle portion 40 onto, cam 55 is limited from rotation in rotation limitation protrusion 57 Groove portion 56 in the state (referring to Fig.1 2) extracted out.If being in the state, due to allowing the rotation of axle portion 40, therefore accompanying action It is moved along the cam surface 64 of action cam 63 position of the rising of cam 63, action pin 65.That is, axle portion 40 is in defined one Direction (for example, in occasion of holding member 31A, counter clockwise direction, in the occasion of holding member 31D, clockwise) and revolve Turn, each claw 42 (base portion 41) is in horizontal direction rotary motion to the height and position abutted with margining tablet 38 (limitation protrusion 39).

It being in as a result, in the 1st stop position X1, claw 42 does not rub to the upper surface of laminated body 4, and from laminated body 4 It is upper hidden, and to this and the edge of sheet body that is loaded on claw 42 extends as the crow flies, coincide with the shape of the upper surface of laminated body 4 State.

Then, each claw 42 in axle portion 40 circumferential direction and 72 ° of rotary motion, and action pin 65 reach cam surface 64 lower end The rotary motion in portion, each claw 42 stops (referring to Fig.1 3).

Herein, if action cam 63 is made to decline, by the bias force of helical spring 61, axle portion 40 is depressed into down Side.Rotation limitation protrusion 57 is inserted into the groove portion 56 for the rotation limitation cam 55 for being different from positioning before the rotational motion as a result, 1 groove portion 56 in.That is, each claw 42 declines and stops at stop position X1~X5 different from positioning before the rotational motion 1 adjacent stop position X1~X5 (referring to Fig.1 4).

It is in the state that laminated body 4 is pressed by the claw 42 for stopping at the 1st stop position X1 as a result,.Shown in Figure 14 Example in, on the cathode for stopping at the 1st stop position X1 separator claw 42B press laminated body 4 (separator 2) shape State.

In the state, stops the attraction of suction portion 17, release the suction of sheet body.Then, it is left upward in suction portion 17 (referring to Fig.1 5) afterwards, reference position of the action cam 63 back to the lower section of turntable 6.

In addition, cam 63 is acted while back to reference position, by above-mentioned driving mechanism, in defined 1 side To (for example, in occasion of holding member 31A, counterclockwise, in the occasion of holding member 31D, clockwise) rotation fortune It is 72 ° dynamic.Action cam 63 (cam surface 64) and the circumferential relative position relation of the action pin 65 of axle portion 40 are in above-mentioned as a result, The position relationship (referring to Fig.1 0) of wait state.

, can be in defined 1 direction by the way that above-mentioned a series of action is repeated, 72 ° of ground make each claw 42 revolve every time Transhipment is dynamic.But in the occasion of present embodiment, it is in stacking operation to make " on anode to divide (other than after the completion of stacked) Spacing body claw 42D " is from the 1st stop position X1, and when being rotated, the lower end of cam surface 64 is reached in above-mentioned action pin 65 At the time of (referring to Fig.1 3) last stage, make action cam 63 in defined 1 direction (for example, in the field of holding member 31A Close, counterclockwise, in the occasion of holding member 31D, clockwise) 72 ° of rotary motion.As a result, stop each claw 2 In 72 ° of position of rotary motion, it in addition can further increase 72 ° of 144 ° of degree and be rotated.

As " the separator claw 42D on anode " made in present embodiment from the 1st 144 ° of stop position X1 rotary motions At the time of, have in stacking operation (other than when stacked start), by anode foil 1 by anode foil loading attachment 11A Anode foil 1 is transported by anode foil loading attachment 11E and is loaded by the case where transporting and being loaded into stacking operation position R2 The case where stacking operation position R6.

In addition, be it is stacked after the completion of, it is and other when carrying out the taking-up operation of laminated body 4 in taking out job position R11 Occasion it is identical, by " separator claw 42D on anode " from the 1st stop position X1, in defined 1 direction and rotary motion 72°。

Below as the flow of 1 supporting plate P, specifically the flow of the stacking operation of above-mentioned stacking apparatus 5 is illustrated. In the occasion of present embodiment, the stacked step carried out during 1 circle of rotation of turntable 6 is repeated by with stipulated number Suddenly, laminated body 4 is completed.

First, according to above-mentioned tables of data, at the time of regulation and by being taken into homework department 7, supporting plate P is set to positioned at taking Enter on the defined stacked platform S on the turntable 6 of job position R1.

Then, turntable 6 rotates 30 °, and thus supporting plate P moves to stacking operation position R2.If supporting plate P stops at stacked work Industry position R2, then the interval between the intermitten of turntable 6 anode foil 1 is loaded by anode foil loading attachment 11A On supporting plate P.

Herein, first, by the conveyer 14 of the suction anode foil 1 in the reservoir 12 of anode foil loading attachment 11A Suction portion 17 be directed on supporting plate P.Then, suction portion 17 drops in the state of suction anode foil 1, which is loaded In on supporting plate P.Then, suction portion 17 stops in the state that anode foil 1 is pressed on to lower section (supporting plate P).

Stacking operation R2 was shifted in supporting plate P originally, and the 1st stop position X1 (pressing position) is stopped in gutter K State (with reference to Fig. 8).In addition, if anode foil 1 is loaded on supporting plate P1, each holding member 31 rises.Claw as a result, 42 rise to the height and position limited by margining tablet 38 of suction portion 17.

Then, each holding member 31 rotates, by cathode claw 42A rotary motions to the 1st stop position X1 (with reference to Fig. 4). If cathode claw 42A moves on to the 1st stop position X1, each holding member 31 declines.It is in 4 angles of anode foil 1 as a result, The state that each adjacent corner is pressed by cathode claw 42A.

If in the state for pressing 4 angles of anode foil 1 by cathode claw 42A, stop the suction of suction portion 17 Draw, releases the suction of anode foil 1.In addition, it is in each stacking operation below and identical, and the attraction of suction portion 17 stops Only independent of the above-mentioned moment at the time of (suction of sheet body releases), sheet body is pressed on lower section by suction portion 17, if in sheet body After the state for not generating dislocation etc., 1 can also.

Then, suction portion 17 rises, and turntable 6 rotates 30 °, and supporting plate P moves on to stacking operation position R3 as a result,.During this period, The state for maintaining each adjacent corner of anode foil 1 to be pressed by cathode claw 42A.

If supporting plate P stops at stacking operation position R3, the interval between the intermitten of turntable 6 passes through separation Separator 2 is loaded into the laminated body 4 on supporting plate P by part loading attachment 11B.

Herein, first, by the conveyer 14 of the suction separator 2 at the reservoir 12 of separator loading attachment 11B Suction portion 17 be directed on supporting plate P.Then, suction portion 17 drops in the state of suction separator 2, which is loaded In in above-mentioned anode foil 1.Then, state of the suction portion 17 on separator 2 to be pressed on to lower section (anode foil 1) stops.At this In, the edge part (exposed portion) of the separator 2 exposed from the foreign side of the peripheral part of suction portion 17 is in be loaded into press and bear State on the anode foil claw 42A of pole foil 1.

If separator 2 is loaded into anode foil 1, each holding member 31 rises.Claw 42, which rises to, as a result, passes through The margining tablet 38 of suction portion 17 and the height and position limited.Then, it is on one side in the 1st stop position X1, cathode claw 42A The edge part of separator 2 is lifted, one side opposing negative polarity foil 1 and the state that floats slightly.

Then, each holding member 31 rotates, and makes cathode claw 42A rotary motions to the 2nd stop position X2.Meanwhile the 1st Stop position X1, in the way of replacing cathode claw 42A, separator claw 42B is carried out from the 5th stop position X5 on cathode Rotary motion (with reference to Fig. 5).

If separator claw 42B moves to the 1st stop position X1 on cathode, each holding member 31 declines.Locate as a result, The state pressed by each adjacent corner at 4 angles of separator 2 is by separator claw 42B on cathode.If being in the shape State then stops the attraction of suction portion 17, releases the suction of separator 2.

Then, suction portion 17 rises, and turntable 6 rotates 30 °, and supporting plate P moves to stacking operation position R4 as a result,.In this phase Between, maintain each adjacent corner of separator 2 by cathode separator claw 42B by the state that presses.

If supporting plate P stops at stacking operation position R4, the interval between the intermitten of turntable 6 passes through anode Cathode foil 3 is loaded into the laminated body 4 on supporting plate P by foil loading attachment 11C.
