From the take-up shaft sliding direction X + side in order flange (51L _{1 (1))} ~ flange (51L _{8 (8)),} if a a flange in a rotating coordinate system of the right side view (plus the take-up direction R) (51L ₁ (1) and 51L ₅ (5) have guide grooves 53L ₁ and 53L _{5 in the} range of 0 degree to 90 degree (the oblique line part by a chain line), the flange part 51L ₂ (2), 51L ₆ (6 )) Has guide grooves 53L ₂ and 53L _{6 in the} range of 90 ° to 180 ° (the slanted portion by the solid line), and the flange portions 51L ₃ (3) and 51L ₇ (7) are 180 to 270 degrees. With guide grooves 53L ₃ and 53L ₇ in the range (the oblique portions by solid lines), the flange portions 51L ₄ (4) and 51L ₈ (8) have guide grooves 53L ₄ , in the range of 270 to 360 degrees. 53L ₈ ) (the hatched portion by the dashed line).

According to the arrangement of the guide grooves, the center of the flange portion 51L itself is wound around the flange portion 53L ₁ (1), 53L ₅ (5) and the flange portion 51L ₃ (3), 51L ₇ (7). The reel is symmetric about the axis, and the flange portions 51L ₂ (2), 51L ₆ (6) are symmetric about the flange portions 51L ₄ (4), 51L ₈ (8) and the winding axis, The center of the entirety of the member 53L is located on the winding axis.

In addition, the transmitting side flange portion _{(51L 2 (2), 51L} 4 (4), 51L 6 (6)) take-up direction R the lower-side guide edges of the _{(54L 2, 54L 4, 54L} 6) with respect to the accommodating each With respect to the side flange portions 51L ₃ (3), 51L ₅ (5), and 51L ₇ ( ₇ ), the same plane as the upper guide edge portions 54L ₃ , 54L ₅ , 54L _{7 in the} winding direction R is interposed therebetween. To face.

In the case of the present embodiment, in order to ensure that when the sense of the film bending does not occur in the film, a transmission-side guide edges _{(54L 2, 54L 4, 54L} 6) and the receiving-side guide edges (54L _3, 54L _5, 54L ₇ ) chamfering is carried out at a constant angle so as to form slopes parallel to each other.

For example, as shown in Figs. 13A, 13B and 12A, the guide edge portion 54L ₂ of the flange portion 51L ₂ (2) is obliquely lower than the horizontal plane including the winding axis. Guide slope 58L ₂ which is inclined to the side surface is formed, and guide slope 58L ₃ which is inclined upwardly at an angle with respect to a horizontal plane including a winding axis is formed in the guide edge portion 54L ₂ of the flange portion 51L ₃ (3). Formed.

The same applies to the other sending side guide edge portions 54L ₄ and 54L ₆ and the receiving side guide edge portions 54L ₅ and 54L ₇ .

Here, with reference to FIG. 14, setting of the chamfering angle (alpha) of the guide edge part 54L is demonstrated.

When the film is wound on the next winding shaft portion 52L ₂ from the outermost portion of the film wound on the winding shaft portion 52L ₁ via the space shaft portion 520L ₁ , it is said that the film is induced so that there is no bending as described above. As needed, it is desirable to take a trajectory that becomes a spiral curve on a particular cylindrical curved surface.

Therefore, in the case of the present embodiment, first, the flange portions 51L _{1 to} 51L ₄ among the reel members 50L, the winding shaft portions 52L ₁ and 52L ₂ and the space shaft portions 520L ₁ interposed therebetween are targeted. After that, when pulling the intersection point P1 of the uppermost bus bar L1 on the film 2 of the winding diameter D and the inner surface of the flange part 51L ₁ to the starting point, the film 2 is in contact with the injured portion. The straight line L2 with respect to the straight line L3 drawn parallel to the straight line L2 from the intersection P2 of the innermost surface of the straight line L2 and the flange portion 51L ₄ and the lowest bus bar on the winding shaft portion 52L ₂ . , A hypothetical cylindrical curved surface C containing L3 as the outermost busbar and integrally similar to the side surface of the space axis portion 520L ₁ is assumed.

Subsequently, the film edge trajectory S1 which becomes a spiral curve by connecting the point P3 on the imaginary cylindrical curved surface C and the point P3 separated by the equivalent of the film width from the point P2 on the straight line L3. The film edge trace S2 which becomes a spiral curve is connected by connecting the point P4 separated from the intersection P1 by the part corresponding to the film width on the intersection P2 and the straight line L2.

And, defined as the angle in contact with the chamfer angle α3 is a guide surface (58L ₃₎ the film edge trace (S2) of the flange (51L _3). The chamfer angle α2 of the flange (51L ₂₎ is equal to the chamfer angle α3 of the flange (51L _3).

The chamfering angles α1 and α4 to α8 of the other flange portions 51L ₁ , 51L _{4 to} 51L ₈ are also the same as the chamfering angle α3 of the flange portions 51L ₃ .

Moreover, the guide inclined surface 58L ₂ of the flange part 51L ₂ may contact with the case where it is not in contact with the film edge trace S1 in relation to the length d of the space shaft part 520L ₁ .

When the length d1 of the space shaft portion 520L ₁ that the guide inclined surface 58L ₂ does not contact the film edge trajectory S1 is set, the length d1 of the space shaft portion 520L ₁ and the flange portion 51L ₂ are set. For the upper guide edge portion 54L ₂ and the flange portion 51L ₃ opened 180 degrees thereon, the virtual cylindrical curve C is enlarged along the film guide space defined by the lower guide edge portion 54L ₃ . As a result, since the advancing angle of the spiral curve becomes large, there is an advantage that the film can be loosely drawn. In this embodiment, such a point is used.

On the other hand, when Although not adopted in the present embodiment, the inclined guide surfaces (58L ₂₎ Set the length d2 (<d1) of the space, the shaft (520L ₁₎ in contact with the film edge trace (S1), the said film derived space passed to a cold stiff pull the film in accordance with the reduced, and by the flange (51L ₃₎ inclined guide surfaces (58L ₂₎ and flange lead to end edge amount of the film by the guide inclined surfaces (58L ₂₎ both of the portions (51L ₂₎ of There is an advantage that the looseness of the winding can be prevented.

It is a front view which shows the film container in which the film was wound on the reel member of this embodiment.

As shown in Fig. 15, the film container 70C is a reel member 50L of the present embodiment which is wound with a film to be described later, but the film 2 of the wound portion is a guide inclined surface 58L ₃ , 58L ₅ , respectively. , 58L ₇ ) and on a curve similar to the spiral curve.

However, the film of the part wound up by making at least the part which contact | connects the film 2 among the cross section of the guide edge part 54L (not chamfered), or the side surface of the space axis part 520L near the virtual cylindrical curve C. (2) can come on a curve more approximated to the film edge trajectories S1 and S2.

16 is a diagram illustrating an example in which the reel member of the present embodiment is divided into a plurality of component elements.

Although the reel member 50L mentioned above is comprised integrally, you may comprise so that the reel member 50L of this embodiment can be assembled by several component element.

For example, Figure a flange portion (51L ₁₎ and the take-up shaft (52L ₁₎ as shown in 16 with a first part element (501L), and further, and a flange portion (51L ₈₎ to the part elements (502L), also plan After the branch portion 51L ₂ , the flange portion 51L ₃ , the space shaft portion 520L ₁ , and the winding shaft portion 52L ₂ are the component elements 503L, the component elements 501L and the component elements 503L are connected to each other. At the same time, the component element 503L and the component element 502L can be connected to each other.

And such a reel member 50L connects each component element 501L-503L out of phase every 90 degrees, so that the number of flange parts 51L can be set to arbitrary integer multiple with respect to the unit configuration number n. do.

In the present embodiment, the guide grooves 53L ₁ and 53L ₈ were formed in the flange portions 51L ₁ (1) and 51L ₈ (8) from the viewpoint of uniformity of weight balance. It is unnecessary in that respect.

Therefore, the flange portion 51L having the guide groove 53L is arranged as described above by the integral number of the structural unit number n from the viewpoint of the uniformity of the weight balance and the protection of the film, and then the guide grooves 53L on these two outer sides. The flange part 51L which is not formed) can also be arrange | positioned.

The pressure plate 45 is configured to elastically support the moving plate 44 side by a coil spring (not shown) in a state of being engaged to slide only the slide shaft 42 without screwing with the drive shaft 41.

In addition, the moving plate 44 and the pressure plate 45 are both formed in a ring shape, for example, so as to contact only the outer peripheral portion of the flange portion 51 of the reel member 50.

Next, several types of reel parts 50A-50L of 1st-10th embodiment are given to the multistage winding system 1 which was mentioned above, for example for preferable embodiment of the winding method of the film which concerns on this invention. The application case will be described as an example.

19-24 is a figure which showed the state which a film winds with the reel member of this invention about the winding method of the film of this embodiment in the left side view and the front view.

FIG. 25A is a left side view of the film container of the present embodiment, and FIG. 25B is a front view of the film container.

As shown in FIG. 17, first, the reel member 11 wound around the film 2 is attached to the delivery device 10, and for example, the reel member 50A of the first embodiment is attached to the winding device 20. 51A of the flange portion 51A on the movable plate 44 side (the rightmost side in FIG. 17) of the winding device 20 and the right flange portion 13 of the delivery device 10 are hereinafter referred to as the "right flange portion 13a". The winding-side reel member 50A is positioned with respect to the delivery-side reel member 11 so that it may be arrange | positioned on the same plane.

Next, the film 2 taken out from the delivery side reel member 11 is wound around the winding shaft portion 52A of the winding side reel member 50A. Here, for convenience of explanation, as shown in Fig. 1 (a), the first flange portion 51A ₁ , the second flange portion 51A ₂ , and the third flange 51A of the reel member 50A are sequentially turned from the right side. The first winding shaft portion, which is the branch 51A ₃ and the fourth flange portion 51A ₄ , and the one between the first and second flange portions 51A ₁ , 51A ₂ among the winding shaft portions 52A of the reel member 50A. 52A ₁ , between the second and third flange portions 51A ₂ , 51A ₃ , and as the second winding shaft portion 52A ₂ , between the third and fourth flange portions 51A ₃ , 51A ₄ . and in that the third winding shaft portion (52A _3).

Then, the winding motor 32C is operated in response to a command through the control unit 60 described above to start the rotation of the winding shaft 31, and the count of the number of pulses of the winding motor 32C is started.

Thus, the reel member 50A winds the film 2 loaded by the delivery device 10 in the unwinding state to the first winding shaft 52A ₁ (FIGS. 19A and 19B). Reference).

After the first winding shaft portion 52A ₁ of the reel member 50A winds up the portion of the adhesive film 2 and starts winding the release film 2a as shown in Figs. 20 (a) and 20 (b), The winding-up part 2b which the control part 60 contact | connects the sending side peeling film 2a of the peeling film 2a and the winding-up roll-shaped film 2 by the count of the pulse number of the winding motor 32c is 2nd. when it is determined to have reached within the guide groove (53A) of the flange (51A _2), it stops the operation of the take-up motor (32c).

The drive shaft 41 is rotated by operating the slide motor 43b by a predetermined number of pulses according to a command through the control unit 60. As a result, as shown in FIGS. 21A and 21B, the reel member 50A has a position where the second flange portion 51A ₂ is on the delivery side right flange portion 13a along the winding shaft 31. Move over until you reach the equivalent distance. In this case, since the sending side peeling film 2a is twisted with respect to the roll-side roll-shaped film 2, the peeling film 2a is projected from the guide groove 53A of the second flange portion 51A ₂ . me approach the third flange (51A _3).

Figure 22 (a), Figure 22 (b) is rotated back to the reel member (50A) in the state as shown in the second flange portion (51A ₂₎ a peel-off film (2a) on the guide edge (54A) takes a .

Thereafter, as shown in FIGS. 23A and 23B, the reel member 50A holds the release film 2a in the state caught in the _second flange portion 51A ₂ as the second winding shaft portion ( 52A ₂ ), when time passes, the discharging of the release film 2a is terminated, and the next adhesive film 2 is sent out, so that the film 2 is wound.

On the other hand, when the slide motor 43b is operated in response to a command through the control unit 60, the reel member 50A is disposed on the same plane as the second flange portion 51A ₂ on the delivery side right flange portion 13a. Return to

As such, FIG. 24 (a), Figure 24 (b) the reel member (50A), as shown in the second take-up shaft (52A ₂₎ is wound in a parallel to the film (2) from the transmitting side with respect to the state.

Next, the third winding shaft 52A ₃ of the reel member 50A is also wound as described above.

Thus, by giving the reel member 50A the winding-up method of the film of this embodiment, as shown to FIG.25 (a), FIG.25 (b), the peeling film 2a of the film 2 is carried out from the sending side. The film container 70A which wound the film 2 in roll shape in each winding shaft part 52A in the state which wound the exposed part from 51 A of flange parts to the winding shaft part 52A is obtained.

27-30 is a figure which shows the state which a film winds by the other reel member which concerns on this invention about the winding method of the film of this embodiment.

In the winding method of this film, the reel member coupling body (henceforth simply "reel member 50K") with which the reel member 50K of 9th Embodiment mentioned above was couple | bonded is used.

In the case of the present embodiment, the winding method itself is not different from the winding method using the reel member 50A of the first embodiment described above, but in a shape different from the reel member 50A of the reel member 50K. Mainly explain the resulting effect.

27, 29, and 30 correspond to FIG. 22 (a), FIG. 23 (a), and FIG. 24 (a), respectively.

As shown in FIG. 27, in this embodiment, after winding the film 2 to one winding shaft part 52K, the reel member 50K itself itself in the state in which the film 2 reached one guide groove 53K. Sliding and rotating. Thereby, the film 2 is in contact with the guide edge 54K in the state spanning the flange portion 51K.

As shown in FIG. 28, when the reel member 50K is further rotated, the film 2 moves in the direction in which the contact 2c with the inner edge 54K faces the first locking groove 57K ₁ , while the film The portion 2d released from the roll of (2) moves in the direction toward the second locking groove 57K ₂ .

Then, the film 2 as shown in Fig. 29 over the edges of the two flanges (51K) in a state being in the second locking groove (57K ₂₎ at the same time the first jam is exposed to the bottom groove (57K ₁₎ Takes

Subsequently, as shown in FIG. 30, the film 2 is wound on the next winding shaft portion 52K and wound as it is, while maintaining the tension between the first and second locking grooves 57K ₁ and 57K ₂ .

Moreover, another embodiment of the winding-up method of the film of this invention is described.

For example, in this invention, the winding shaft part 52 which rolled up the film from the viewpoint of protecting it from being broken when it pulls a film using any one of the reel members 50A-50L of 1st-10th embodiment; In addition, at least one winding shaft portion 52 which does not sense the film 2 is interposed between the winding shaft portions 52 to which the film is to be wound, that is, the winding shaft portion 52 may be skipped one by one to wind the film 2. have.

According to such a structure, the flange part 51 for pulling out from the winding-shaft part 52 which wound the film 2, and the flange part 51 for winding around the winding-shaft part 52 to wind the film 2 The film 2 in between is pulled at a gentle angle as compared with the case where the film is wound around all of the winding shaft portions 52.

However, it is preferable to apply this method to the reel member 50F of the said 6th embodiment.

In this case, the film 2 is pulled while being in contact with the curved surface portion in the guide groove 53F of the flange portion 51F, the winding shaft portion 52F is skipped one by one, and the guide groove of the other flange portion 51F adjacent thereto. After dropping into the locking groove 57F in the 53F, it is wound around the next winding shaft portion 52F.

Thus, by applying the so-called skipped film winding method described above to the reel member assembly 60F to which the reel member 50F is bonded in multiple numbers, as shown in FIG. 26, the film 2 is wound by a gentle angle. The true film acceptor 70B is obtained.

On the other hand, it can also be wound using the reel member which added the spacer for winding between each winding-shaft part of a sending side and a receiving side from a viewpoint of pulling smoothly so that a film may not be bent similarly by the winding method of the film of another embodiment. have.

In this case, it is preferable to use the reel member 50L of 10th Embodiment shown to FIG. 12 (a), for example from a viewpoint of achieving uniform weight balance.

Moreover, when using this reel member 50L, it is necessary to shift the timing which winds a film, ie, the timing which slides the winding shaft part 52L by 90 degrees.

Further, when a winding method in another embodiment of the film, apply the first embodiment of the reel member (50A) shown in Fig on the multi-stage winding machine (1), attached to the first take-up shaft portion (52A ₁₎ When the winding-up part 2b of the sending side peeling film 2a reaches the guide edge 54A of the 2nd flange part 51A2 in the step of winding the film ₂ , rotation of the reel member 50A is stopped. You can also

In this case, after stopping rotation of the reel member 50A, the peeling film 2a is fastened to the guide edge 54A of the _2nd flange part 51A2, moving the reel member 50A axially. Processing thereafter is the same as in the above embodiment.

Moreover, 2nd, 3rd, and 5th embodiment shown to FIG. 3, FIG. 4 (a), FIG. 4 (b) or FIG. 6 (a), FIG. 6 (b) to the multistage winding system 1 mentioned above. When one of the reel members 50B, 50C or 50E is applied, the shape and the size of each guide groove 53B, 53C, 53E are compared with the case where the reel member 50A of the first embodiment is applied. different.

Therefore, when using the reel members 50B, 50C, and 50E of these 2nd, 3rd, and 5th embodiment, it is necessary to change the timing which stops rotation of the reel member 50. FIG.

However, in the step of winding the adhesive film 2 to the other points, for example, the first winding shaft portion 52, the release film 2a is passed through the guide groove 53 of the second flange portion 51, After moving to the 2 winding shaft part 52, the 2nd winding-shaft part (whilst walking on the guide edge 54 and hanging the peeling film 2a at the guide edge 54 of the 2nd flange part 51 The point of winding after moving to 52) is the same as that of the said embodiment.

In addition, when the reel member 50D of 4th Embodiment shown to FIG. 5 (a) and FIG. 5 (b) is applied to the above-mentioned multistage winding system 1, according to rotation of each flange part 51D, Since the release edge 2 can be hung on the guide edge 54D of the engaging projection 56D after sliding the peeling film 2a at the outer circumferential edge portion, the width of the timing for stopping the rotation of the reel member 50D is described in the above embodiment. It can be expanded in comparison with.

Moreover, in the case of this embodiment, the peeling film 2a is made to pass around the engaging protrusion part 56D of each flange part 51D, and it is the same as that of the said embodiment about the point which dried at the guide edge 54D. .

Moreover, when moving the reel member 50 to an axial direction by the winding method of the film of another embodiment, you may continue to rotate in the state which slowed down than the speed at the time of winding the reel member 50.

In this case, the rotational speed of the reel member 50 is such that the release film 2a is applied to the point of passing the release film through the guide grooves 53 of the flange portions 51 or the guide edge 54 of the flange portions 51. This decision is taken into account.

Moreover, when using the reel member 50G, 50H of 7th, 8th embodiment shown to FIG. 9 (a), 9 (b), or FIG. 10 as the winding method of the film of another embodiment, After winding the film around one winding shaft portion 52, the film may be hung in the vicinity of the winding shaft portion 52 by falling the film into the locking groove 57 while being along the guide edge 54 of the flange portion 51. .

Here, the seventh in the embodiment, the film as the clogging by the rotation the stop portion (57G ₃₎ according to the reel member (50G), the retaining hole (57G ₂₎ the motion is constrained in the retaining hole (57G ₂₎ While changing the posture in the inside, the edge portion of the engaging hole 57G ₂ is tensioned and wound around the winding shaft portion 52G in abutting state.

In the case of the eighth embodiment, the film is fixed by being sandwiched between the bottom portions of the locking grooves 57H according to the rotation of the reel member 50H, while keeping the fixed portion expanded in the starting point. It is wound around the winding shaft portion 52H.

Moreover, in the present invention, the locking grooves 57G and 57H of the reel members 50G and 50H and the locking grooves 57F and 57K of the reel members 50F and 50K described above are automatically applied when the film is wound in a multi-stage shape. In addition to being used to fasten the flange 51, these locking grooves 57 automatically perform only the process of winding the film, and in order to fasten the film to the flange 51 by manually performing the film winding operation. Can also be used.

However, in the case of manually winding the film, the guide groove 53 formed in the flange portion 51 does not need the original function of automatically passing the film, and the operator, for example, puts the tip of the film on the winding shaft portion 52. It is only necessary as a working hole in the case of sticking or inserting a film into the locking groove 57, and the locking groove 57 is sufficient without forming the guide groove 53.

Therefore, in the present invention, the locking groove 57 is included in the concept of the guide groove 53 as long as it has a common point in the broad sense of passing the film through the flange portion 51. For example, only the engaging groove 57 can be formed as a "guide groove" without forming the guide groove 53 for the reel members 50F, 50G, 50H, and the guide groove 53 for the reel member 50K. The locking groove 57 including the shape of the groove can be formed as a "guide groove".

As explained above, according to the said embodiment, after winding an adhesive film in one winding shaft part 52 of the reel member 50, the rotation of the reel member 50 is stopped (or reduced), and the reel member 50 is carried out. Since the film winding can be smoothly started in the next winding shaft portion 52 because the film is moved in the axial direction, the film can be wound in a multistage shape while being suppressed to a diameter such that the adhesive does not protrude in the film with respect to the long film. It becomes possible.

When performing the winding method of the film of this embodiment, it becomes more effective to wind an elongated film in multistage shape by using the reel member 50 shown in 1st-10th embodiment.

For example, according to the first to third, fifth to tenth embodiments, since the guide grooves 53 are formed in the flange portions 51, at the stage where the film winding is completed in one winding shaft portion 52, By passing the film through the guide groove 53, the film can be smoothly moved to the next winding shaft 52.

In particular, in the first to third and fifth embodiments, the film is removed from the edge (guide edge) of the guide groove 53, and in the sixth to ninth embodiments, the film is removed from the locking groove 57. While stopping the locking, the film can be wound around the next winding shaft 52 so as not to loosen.

Moreover, about the point which formed the guide groove 53 in each flange part 51, the point which can wind up a film so that it may not protrude from the outer peripheral part of each flange part 51, 2nd, 3rd One winding shaft portion by extending the guide groove 53 near the winding shaft portion 52 as in the fifth and ninth embodiments, and extending the locking groove near the winding shaft portion as in the seventh and eighth embodiments. There is also an advantage that the length of the film (peel film) required for pulling from the 52 to the next winding shaft portion 52 may be short.

In addition, according to the fourth embodiment, since the engagement protrusions 56 are formed on the flange portions 51, the film can be smoothly moved from one winding shaft portion 52 to the next winding shaft portion 52. There is an advantage in that the film can be hanged at the point or the engaging projection 56, and of course, the timing width at which the film is formed can be set wide.

In addition, according to the second to ninth embodiments, the respective reel members 50 are bonded to each other in the axial direction, so that the number of reel members 50 can be appropriately responded according to the degree of elongation of the film. Will be.

And according to 1st-9th embodiment, since each guide groove 53 or each engagement protrusion 56 was arrange | positioned in the same position on the circumference of the flange part 51, when moving a film to an axial direction, When walking a film, it can carry out at the same timing between each flange part 51. FIG.

In addition, according to the sixth embodiment, since the thickness of the flange portion 51 is thickened to a considerable extent, and the portion through which the film in the guide groove 53 passes is made into a curved shape, the film breaks when the film is pulled out. Can be prevented.

In particular, by using a so-called skipping method of the film with respect to such a reel member 50, it is possible to prevent the film from breaking more effectively.                 

Further, according to the sixth to ninth embodiments, since the locking grooves 57 are formed on the guide edges 54 of the guide grooves 53 and the film can be automatically caught by the flange portion 51, the film The film can be prevented from loosening when the film is pulled out.

In particular, since not only the film of the part wound by the winding shaft part 52 can be hooked like the 9th embodiment, but also the film of the outer part which has already been wound can be hooked, looseness of a film can be prevented more effectively.

However, even in the first to fifth embodiments, the film can be prevented from being loosened by winding the film around the winding shaft portion 52 while the film is held in the corner portion or the bottom portion of the guide groove 53. A certain amount of tension must be applied to the film so as not to move in the jammed portion of the guide groove 53, while in the sixth to ninth embodiments, once the film is caught in the locking groove 57, Since the tension applied to the film can then be made to the minimum required size, there is an advantage that it is suitable for winding thin films.

In addition, according to the eighth and ninth embodiments, the center of the flange portion 51 itself is on the winding shaft portion 52, so that the reel member 50 including such a flange portion 51 in the configuration is included. Since it becomes possible to rotate by the uniform rotation moment with respect to it, it can wind up uniformly, giving a minimum tension to a film.

Moreover, since the film container 70 which wound the film on this reel member 50 is stable because the center with respect to the whole is on the winding-shaft part 52, a delivery form can be varied at the time of shipment. .

Further, according to the tenth embodiment, the uniformity of the weight balance of the reel member 50L can be achieved, so that the long film can always be wound with a uniform rotation moment, and the film is smoothly drawn while inducing the film into a spiral shape. The long film can be wound without causing breaks, and as a result, the customer can be provided with a film acceptor 70C containing a film with no breaks (no scraps).

In particular, in the present embodiment, the film is wound in a multi-stage shape while maintaining the uniformity of the weight balance by increasing the number of the winding shaft portions 52L and the flange portion 51L for each unit number n determined in terms of weight balance. The length of can be further increased.

For example, the length of the film which can be wound using the reel member 50L is 200 × by multiplying the unit configuration number n (= 4) by an integer multiple N when 50 meters of film is wound on one winding shaft portion 52L. N meters ("x" represents multiplication).

As described above, according to the present invention, in order to cope with the elongation of the adhesive film, the adhesive film can be wound in a multi-stage shape with a diameter at which the adhesive does not protrude, and a reel member applicable to this can be obtained.
