In the order of the flange part 51 L i (1) to the flange part 51 L ₈ (8) in order from the slide axis X + side of the winding shaft, the rotating coordinate system (winding direction R in positive), the flange portion (1), 5 1 L 5 (5) is 0 ° to 9 0 guided in a range degrees of the groove ₅ 31 ^, 5 3 L 5 have a (hatched portion by dotted line), the flange portion 51 L ₂ (2) and 51 L 6 (6) have guide grooves 53 L ₂ and 53 L ₆ in the range of 90 degrees to 180 degrees (the shaded area by solid lines). flange unit _{5 1 L 3 (3),} 5 1 L 7 (7) is 1 8 0 degree to 2 7 0 degree range in the guide groove 5 3 L ₃ of 5 3 has a L ₇ (hatched portion by a solid line ), the flange portion 5 1 L 4 (4), 5 1 L 8 (8) is 2 7 0 degrees to 3 6 0 degrees range in the guide groove 5 3 L _4, and 5 3 having L ₈ (hatched by broken lines part) . Due to such an arrangement of the guide grooves, the center of gravity of the flange portion 51 L itself is such that the flange portions 53 L i (1) and 53 L ₅ (5) have the flange portions 51 L ₃ (3) and 5 L 1 L 7 (7) is symmetrical with respect to the winding axis, and the flanges 51 L 2 (2) and 51 L 6 (6) are the flanges 51 L ₄ (4) and 51 Ls Since it is symmetrical with respect to (8) and the winding axis, the center of gravity of the entire reel member 53L is located on the winding axis.

In addition, for the flange portions 51 L ₂ (2), 51 L 4 (4), and 51 L β (6) on the feed side, the guide edges 54 L ₂ and 54 L on the lower side in the winding direction R ₄ , 5 4 L ₆ are the guide edges on the upper side in the winding direction R for the receiving flanges 51 L ₃ (3), 51 L 5 (5), and 51 L 7 (7), respectively. It faces 54 L ₃ , 54 L 5 and 54 L ₇ on the same plane.

Further, in the case of the present embodiment, the guide edges 54 4 L ₂ , 54 L 4-on the feeding side are used to prevent the film from being broken when the film is drawn. 5 and 4 L _6, on the receiving guide edge portion of the side _{5 4 L 3, 5 4 L} 5, 5 4 L 7, their respective chamfer is applied at an angle so that parallel the slope to each other are formed Have been.

For example, as shown in the first FIG. 3 (a) (b) and the first 2 diagram (a), the guide edge portions 5 4 L ₂ of the flange portion 5 1 L ₂ (2), the卷取axis guide slopes 5 8 L ₂ inclined obliquely downward with respect to the horizontal plane containing is formed, the guide edges 5 4 L ₂ of the flange portion 5 1 L (3), towards the obliquely with respect to the horizontal plane containing the winding axis Guide slope 5 8 L ₃ that tilts are formed.

Guiding edge portions 54 of the other feed side L _4, 5 and 4 L _6, The same applies to the guiding edge _{5 4 L 5, 5 4 L} 7 of the receiving side.

Here, the setting of the chamfer angle of the guide edge 54L will be described with reference to FIG.

From the outermost portion of the wound film卷取shaft portion 5 2 L, be via the scan Bae one scan shaft 5 2 0 L i Kai pulling the film to the next winding spool 5 2 L ₂ In this case, since the film needs to be guided so as not to be broken as described above, it is preferable to take a locus that forms a spiral curve on a specific cylindrical curved surface.

Therefore, in the present embodiment, first, of the re Ichiru member 5 0 L, flange portion _{5 1 L i~ 5 1 L 4} , the take-up shaft section 5 2 L that is between them, 5 2 L ₂ and space shaft section 5 20 L!

Next, on the virtual cylindrical surface C, a film edge locus that forms a spiral curve by connecting the intersection P 1 and a point P 3 on the straight line L 3 that is away from the intersection P 2 by an amount corresponding to the film width. Consider a film edge locus S 2 connecting the intersection P 2 and a point P 4 on the straight line L 2 that is away from the intersection P 1 by an amount corresponding to the film width to form a spiral curve.

The bevel angle alpha 3 of the flange portion 5 1 L ₃ are guide slopes 5 8 L ₃ is defined at an angle in contact with the film edge trace S 2. The chamfer angle α 2 of the flange 51 L ₂ is the same as the chamfer angle α 3 of the flange 51 L ₃ .

Other flange portion 5 1 1 ^, 5 1 L 4 ~ 5 1 L 3 chamfer angle al, the also a 4 ~ c¾ 8, is the same as the bevel angle (¾ 3 of the flange portion 5 1 L 3 as well.

The guide inclined surface 58 L ₂ of the flange 51 L ₂ is not in contact with the film locus S 1 due to the length d of the space shaft 52 0 L i. There is.

When the guide slope 5 8 L ₂ does not contact the film edge locus S 1, the space shaft 5 2 OL i If the length d 1 is set, the space shaft 5 2 0 L between the length d 1, and the guide edges 5 4 L ₂ of the upper side for the flange portion 5 1 L _2, open 1 8 0 degrees with respect to this, the guide of the lower side are in the flange portion 5 1 L ₃ The virtual cylindrical surface C is enlarged along with the film guiding space defined by the edge portion 54 L ₃ , which leads to an increase in the lead angle of the spiral curve. In the present embodiment, such a point is used.

On the other hand, although not adopted in the present embodiment, the length d 2 (g dl) of the space shaft portion 5 2 OL i is set such that the guide inclined surface 58 L ₂ comes into contact with the film edge locus S 1. If this is done, the above film guiding space will be smaller Although routing of the film is tight with particular, both edges of the film by both the flange portions 5 1 L ₃ of guide inclined surfaces 5 8 L ₃ and guide the flange portion 5 1 L ₂ inclined surfaces 5 8 L ₂ There is an advantage that winding loosening can be prevented by inducing winding.

FIG. 15 is a front view showing a film container in which a film is wound around a reel member of the present embodiment.

As shown in FIG. 15, this film container 70 C is obtained by applying a film winding method described later to the reel member 50 L of the present embodiment, but is wound around. film second portion, respectively, while in contact with the guide inclined surfaces _{5 8 L 3, 5 8 L} 5, 5 8 L 7, is on the curve approximate to a spiral curve.

However, at least the portion of the end surface of the guide edge 54 L (not chamfered) or the side surface of the space shaft portion 52 O L that comes into contact with the film 2 should be close to the virtual cylindrical curved surface C. Accordingly, the film 2 of the routed portion can be placed on a curve that is more approximate to the film edge trajectories Sl and S2.

FIG. 25 (a) is a left side view showing the film container of the present embodiment, and FIG. 25 (b) is a front view showing the film container.

As shown in FIG. 17, first, a reel member 1 on which a film 2 is wound

1 is attached to the sending device 10 and, for example, After attaching the reel member 50 A to the winding device 20, the flange portion 51 A on the moving plate 44 side (the rightmost side in FIG. 8) of the winding device 20 and the right side of the sending device 10. The reel member 50 A on the take-up side is connected to the reel member 11 on the feed side so that the flange portion 13 (hereinafter referred to as “right flange portion 13 a”) is arranged on the same plane. Position.

Next, the film 2 drawn from the reel member 11 on the sending side is wound around the winding shaft portion 51A of the reel member 50A on the winding side. Here, for convenience of explanation, as shown in FIG. 1 (a), the flange portion 51A of the reel member 5OA is sequentially arranged from the right side to the first flange portion 51A and the second flange portion 51A. flanges 5 1 a _2, the third flange portion 5 1 a _3, and a fourth flange portion 5 3 a _4, of卷取shaft portion 5 2 a reel member 5 OA, first, second flange part 5 1 a 1, those between 5 1 a ₂ is a first winding spool 5 2 Ai, second, those between the third flange portion 5 1 a _2, 5 1 a ₃ second and卷取shaft portion 5 2 a _2, third, and fourth flange portions 5 1 a _3, 5 1 a third卷取shaft portion 5 2 a ₃ also to from between _4.

Then, in accordance with the command from the control unit 60 described above, the winding motor 32C is actuated to start the rotation of the winding shaft 31 and the counting of the number of pulses of the winding motor 32C is started. I do.

As a result, the reel member 50A winds up the first winding shaft portion 52Ai while keeping the film 2 loaded by the feeding device 10 stretched (first winding shaft portion 52Ai). 9 (See (a) and (b)).

As shown in FIGS. 20 (a) and (b), after the first winding shaft 52 of the reel member 50A finishes winding the adhesive film 2, the peeling film 2a is wound. After starting to take, the control section 60 counts the number of pulses of the take-up motor 32c so that the release film 2a of the release film 2a and the release-side release film 2a and the take-up roll film 2 are separated. The winding part 2 b that contacts Guide grooves 5 3 of the flange portion 5 1 A ₂ when it is determined that One Sashikaka in A, stops the operation of卷取Ri motor 3 2 c.

In response to a command from the control unit 60, the slide motor 43b is operated for a predetermined number of pulses to rotate the drive shaft 41. Thus, as shown in the second 1 view (a) (b), the reel member 5 OA, the second flange portion 5 1 A ₂ is sending side of the right flange portion 1 3 along卷取shaft 3 1 Move beyond position a until a considerable distance is reached. In this case, since the release film 2 a delivery side is twisted relative to the roll-shaped film 2 of the take-up side, the peeling off Ilm 2 a, the second flange portion 5 1 A ₂ of the guide groove 5 3 A It protrudes and approaches the _third flange portion 51A3.

As shown in the second 2 diagram (a) (b), in this state, by rotating the reel member 5 OA again, release film in the second flange portion 5 1 A ₂ is guiding edge 5 4 A 2 Hook a.

Then, as shown in FIGS. 23 (a) and (b), as the reel member 50A rotates, the peeling film 2a hooked on the second flange portion 51A2 is moved to the second position. The film 2 is wound around the winding shaft portion 5 2 A 2, but after a while, the next adhesive film 2 is fed after the release film 2 a has been sent out.

Meanwhile, by a command from the controller 6 0, by operating the slide Domo Isseki 4 3 b, the reel member 5 0 A, the second flange portion 5 1 A ₂ is sending side of the right flange portion 1 3 Return until it is placed on the same plane as a.

As a result, as shown in FIGS. 24 (a) and (b), the reel member 5OA is wound in a state where the film 2 from the feed side is parallel to the second winding shaft portion 52A2. take.

Hereinafter, with respect to the third卷取shaft portion 5 2 A ₃ of the reel member 5 0 A, subjected to Certificates removal process as described above. In this way, by applying the film winding method of the present embodiment to the reel member 50A, as shown in FIGS. 25 (a) and (b), the film 2 is fed from the feed side. A film container 7 0 in which the exposed portion of the release film 2 a is wound from the flange portion 51 A to the winding shaft portion 52 A, and the film 2 is wound in a roll shape on each winding shaft portion 52 A. Get A.

FIG. 27 to FIG. 30 are views showing the film winding method of the present embodiment in a state where the film is wound by another reel member according to the present invention.

In this film winding method, a reel member assembly 60 K (hereinafter, simply referred to as “reel member 50 K:”) in which a plurality of reel members 50 K of the ninth embodiment described above are joined. ) 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. The operation resulting from the shape different from that of the single-piece member 50A will be mainly described.

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

As shown in FIG. 27, in the present embodiment, after the film 2 has been wound on one winding shaft portion 52K, the film 2 is inserted into the guide groove 53K of the core. In this state, slide the reel member 50 K itself and then rotate it. As a result, the film 2 comes into contact with the inner edge 54 K while straddling the flange portion 51 K.

As shown in FIG. 28, when the reel member 50K is further rotated, the contact 2c of the film 2 with the guide edge 54K is directed to the first locking groove 57Ki. moves in a direction, while the portion 2 d was loose from the film 2 roll is moved in a direction toward the second engaging groove 5 7 K _2. Then, as shown in FIG. 29, the film 2 abuts against the bottom of the second locking groove 57 K ₂ and falls into the first locking groove 57, and the two flange portions 5 1 It is hooked over the 緣 part of K.

Thereafter, as shown in FIG. 30, the film 2 is kept in tension between the first and _second locking grooves 57 K 1 and 57 K ₂ , and the next winding shaft 5 2 It is wound around K and wound as it is.

Further, another embodiment of the film winding method of the present invention will be described. For example, in the present invention, from the viewpoint of protecting the film from being broken when the film is drawn around using any one of the reel members 50A to 50L of the first to tenth embodiments, Between the take-up shaft portion 52 that has finished winding the film and the take-up shaft portion 52 that is about to take up the film next, at least one take-up shaft portion 52 that does not take up the film 2 is interposed. That is, the film 2 can be wound by skipping one winding shaft portion 52.

According to such a configuration, the flange portion 51 for pulling out the film 2 from the winding shaft portion 52 that has finished winding, and the flange portion for winding the film 2 around the winding shaft portion 52 where the film 2 is to be wound. The film 2 between the portion 51 and the film 51 is wound at a gentler angle than when the film is wound around all of the winding shaft portions 52.

However, this method is preferably applied to the reel member 50F of the sixth embodiment.

In this case, the film 2 is wound around the curved portion in the guide groove 53F of the flange portion 51F, and the film 2 is wound around the other flange portion adjacent to the winding shaft portion 52F. After dropping it into the locking groove 57F in the guide groove 53F of 51F, wind it around the next winding shaft 52F.

As described above, the so-called one-shot film winding method described above is applied to the reel member combined body 60F in which a plurality of reel members 50F are combined. As a result, as shown in FIG. 26, a film container 70B in which the film 2 is drawn at a gentle angle is obtained.

On the other hand, as a method of winding the film according to another embodiment, similarly, from the viewpoint of smoothly winding the film so as not to be broken, a spacer for winding the film between the winding shafts on the sending side and the receiving side is used. Winding can also be performed using the added reel member.

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

When the reel member 50L is used, the timing of drawing the film, that is, the timing of sliding the winding shaft portion 52L is determined.

It must be shifted 90 degrees.

In addition, as a method of winding a film according to another embodiment, a case where the reel member 50A of the first embodiment shown in FIG. At the stage where the adhesive film 2 has been wound around the winding shaft portion 5 2 A, the winding portion 2 b of the release film 2 a on the sending side reaches the guide edge 54 A of the _second flange portion 51 A _2. When the reel member 5

It is also possible to stop the rotation of OA.

In this case, after stopping the rotation of the reel member 5 0 A, hooking the release film 2 a in the second flange 5 1 guiding edge of A ₂ 5 4 A while moving the reel member 5 OA in the axial direction. Subsequent processing is the same as in the above embodiment.

In addition, the reel member 5 of the second, third, and fifth embodiments shown in FIGS. 3, 4 (a), (b) or 6 (a), (b) is added to the multi-stage winding system 1 described above. When any one of 0 B, 50 C and 50 E is applied, each guide groove 53 B, The shape and size of 53 C and 53 E are different.

Therefore, when the reel members 50B, 50C, 50E of the second, third, and fifth embodiments are used, it is necessary to change the timing for stopping the rotation of the reel member 50. is there.

However, for other points, for example, at the stage when the adhesive film 2 has been wound around the first winding shaft portion 52, the release film 2a is passed through the guide groove 53 of the second flange portion 51. Move to the second take-up shaft 52, and then wind it while hooking it with the guide 緣 54.Or, pull the release film 2a on the guide edge 54 of the second flange 51, It is similar to the above embodiment in that it is wound after being transferred to the winding shaft 52.

Furthermore, when the reel member 50D of the fourth embodiment shown in FIGS. 5 (a) and 5 (b) is applied to the multi-stage winding system 1 described above, the rotation of each flange portion 51D As a result, since the release film 2a can be slid on the outer peripheral edge thereof and then hooked on the guide edge 54D of the engagement projection 56D, the rotation of the reel member 50D is stopped. It is possible to increase the width of the timing to be performed as compared with the above embodiment.

In the case of the present embodiment, the point that the release film 2a passes through the periphery of the engaging projection 56D of each flange portion 51D and is hooked at the guide edge 54D is the same as in the above-described embodiment. Is the same as

In addition, as another method of winding the film, when the reel member 50 is moved in the axial direction, the reel member 50 keeps rotating at a speed lower than the speed at which the reel member 50 is wound. It is also possible.

In this case, the rotation speed of the reel member 50 is determined by the point at which the release film passes through the guide groove 53 of each flange 51 and the point at which the release film 2a is hooked on the guide 緣 54 of each flange 51. Decide in consideration.

9 (a), 9 (b) and 9 (b) show a film winding method according to another embodiment. Alternatively, when either one of the reel members 50 G and 50 H according to the seventh and eighth embodiments shown in FIG. 10 is used, the film is wound around one winding shaft portion 52. After finishing, it is also possible to lock the film in the vicinity of the winding shaft 52 by dropping the film along the guide edge 54 of the flange 51 and dropping it into the locking groove 57.

Here, in the seventh embodiment, the film moves in the engaging holes 5 within 7 G ₂ by being blocked with the rotation of the reel member 5 0 G, the stop portion 5 7 G ₃ missing There is restrained, keep up with-out Certificates the winding spool 5 2 G while contacting with nervous edge portion of the engagement stop holes 5 7 G ₂ while changing the attitude in the locking hole 5 7 G _2.

Further, in the case of the eighth embodiment, the film is fixed by being sandwiched between the bottom portions of the locking grooves 57H with the rotation of the reel member 50H. Wrap around the winding shaft 52H while keeping the tension as the starting point.

In the present invention, such locking grooves 57 G and 57 H of the reel members 50 G and 5 OH, and the locking grooves 57 F and 50 F of the aforementioned reel members 50 F and 50 K, 57 K is used to automatically lock the flange portion 51 when the film is wound in a multi-stage shape, and these locking grooves 57 automatically control only the process of winding the film. It can be used to lock the film to the flange portion 51 when performing the work of drawing the film manually.

However, when the film is manually routed, the guide groove 53 provided in the flange portion 51 does not need the original function of automatically allowing the film to pass therethrough. It is only required as a working hole, such as when affixing to the take-up shaft 52, or when inserting a film into the locking groove 57, and the locking groove is not provided without the guide groove 53. 5 7 only But it is enough.

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 a broad sense that the film passes through the flange portion 51. For example, with respect to the reel members 50 F, 50 G, and 5 OH, only the locking grooves 57 can be provided as “guide grooves” without providing the guide grooves 53. For 0 K, a locking groove 57 including the shape of the guide groove 53 can be provided as a “guide groove”.

As described above, according to the above-described embodiment, after the adhesive film is wound on one of the winding shaft portions 52 of the reel member 50, the rotation of the reel member 50 is stopped (or decelerated). Since the reel member 50 is moved in the axial direction afterwards, the winding of the film can be started smoothly at the next winding shaft portion 52. It is possible to wind in multiple steps while keeping the diameter of the adhesive so as not to protrude.

When the film winding method of the present embodiment is performed, by using the reel member 50 shown in the first to tenth embodiments, the elongated film can be wound in multiple stages. Taking becomes more effective.

For example, according to the first to third and fifth to tenth embodiments, since the guide groove 53 is provided in each flange 51, the film can be wound by one winding shaft 52. When the film is completed, the film can be smoothly moved to the next winding shaft 52 by passing the film through the guide groove 53.

In particular, in the first to third and fifth embodiments, the film is hooked at the guide groove 53 (the inner edge of the guide groove). In the sixth to ninth embodiments, the locking groove 5 is used. By hooking while locking the film in step 7, the film can be wound around the next winding shaft 52 without loosening the film.

Furthermore, regarding the provision of the guide groove 53 in each flange 51, There is an advantage that the film can be wound so as not to protrude from the outer peripheral portion of the flange portion 51, and, as in the second, third, fifth and ninth embodiments, the guide groove 53 is formed by the winding shaft portion 52. By extending the locking groove to the vicinity of the winding shaft as in the seventh and eighth embodiments, There is also an advantage that the length of the film (release film) required to be routed around the winding shaft portion 52 is short.

Further, according to the fourth embodiment, since the engagement projections 56 are provided on each flange 51, the film is transferred from one winding shaft 52 to the next winding shaft 52. In addition to the point that the film can be moved smoothly and that the film can be hooked by the engaging projections 56, there is an advantage that the timing of performing these operations can be set wider.

Further, according to the second to ninth embodiments, since the reel members 50 are connected to each other in the axial direction, the number of connected reel members 50 depends on the length of the film. By increasing or decreasing the number, it becomes possible to respond appropriately.

Furthermore, according to the first to ninth embodiments, each guide groove 53 or each engagement protrusion 56 is arranged at the same position on the circumference of the flange 51. When moving in the direction or hooking the film, it can be performed at the same timing between the flange portions 51.

Further, according to the sixth embodiment, since the thickness of the flange portion 51 is made considerably large and the portion through which the film passes in the guide groove 53 is formed into a curved surface, the The film can be prevented from being broken. In particular, for such a reel member 50, by using a so-called one-shot film winding method, the film can be more effectively prevented from being broken.

Furthermore, according to the sixth to ninth embodiments, on the guide edge 54 of the guide groove 53 Since the locking groove 57 is provided in the frame, it is possible to automatically lock the film to the flange portion 51, so that it is possible to prevent the film from being loosened when the film is pulled around.

In particular, as in the ninth embodiment, it is possible to not only lock the portion of the film wound around the winding shaft 52, but also lock the portion of the film that has already been wound. Therefore, loosening of the film can be more effectively prevented.

However, even in the first to fifth embodiments, the film can be prevented from being loosened by winding the film around the winding shaft 52 while the film is hooked on the corner or the bottom of the guide groove 53. In this case, it is necessary to keep applying a certain amount of tension to the film so that the film does not move from the portion where the guide groove 53 is hooked, while in the case of the sixth to ninth embodiments, Once the film is locked in the locking grooves 57, the tension applied to the film can be reduced to the minimum necessary, which is advantageous for winding a thin film.

Further, according to the eighth and ninth embodiments, the center of gravity of the flange portion 51 itself is located on the winding shaft portion 52, and thus the flange including such a flange portion 51 in the configuration is provided. Since the film member 50 can be rotated with a uniform rotational moment, the film can be wound uniformly while applying the minimum necessary tension to the film.

In addition, the film container 70 in which the film is wound on the reel member 50 has a stable center of gravity on the winding shaft 52, so that the film container 70 is delivered at the time of shipment. Various widths can be provided for the configuration. Further, according to the tenth embodiment, by equalizing the weight ratio of the reel member 50L, a long film can be always wound up with a uniform rotational moment, and The spiral By winding the film smoothly while guiding it into a shape, it is possible to wind a long film without breaking, and as a result, the film storage that stores the film without breaks (no discarded parts) for the customer Body 70 C can be provided.

In particular, in the case of this embodiment, the weight balance is maintained uniform by increasing the number of the winding shaft portion 52 L and the flange portion 51 L for each unit number n determined from the viewpoint of weight balance. As it is, the length of the film to be wound in a multi-stage can be further increased.

For example, the length of the film that can be wound using the reel member 50 L is assuming that 50 m of film is wound on one winding shaft 52 L. The number of unit units n (= 4) Multiplied by an integer multiple N gives 200 XN meters ("X" indicates multiplication). Industrial applicability

As described above, according to the present invention, in order to cope with a longer adhesive film, the adhesive film can be wound in a multi-stage shape with a diameter such that the adhesive does not protrude. A possible reel member can be obtained.
