  The chamfering angle α3 of the flange portion 51L3 is determined such that the guide slope 58L3 is in contact with the film edge locus S2. Further, the chamfer angle α2 of the flange portion 51L2 is the same as the chamfer angle α3 of the flange portion 51L3.

  The chamfer angles α1 and α4 to α8 of the other flange portions 51L1 and 51L4 to 51L8 are similarly the same as the chamfer angles α3 of the flange portion 51L3.

  Note that the guide inclined surface 58L2 of the flange portion 51L2 may or may not come into contact with the film edge locus S1 because of the relationship with the length d of the space shaft portion 520L1.

  When the length d1 of the space shaft portion 520L1 is set such that the guide inclined surface 58L2 does not contact the film edge locus S1, the length d1 of the space shaft portion 520L1 and the upper guide edge portion 54L2 with respect to the flange portion 51L2 And the virtual cylindrical curved surface C is enlarged along with the film guiding space defined by the lower guide edge 54L3 in the flange portion 51L3, which is 180 degrees apart from this, and thereby the advance angle of the spiral curve Therefore, there is an advantage that the drawing of the film becomes gentle. In this embodiment, such a point is used.

  On the other hand, although not adopted in the present embodiment, when the length d2 (<d1) of the space shaft portion 520L1 is set such that the guide inclined surface 58L2 is in contact with the film edge locus S1, the above film guide space As the film becomes smaller, winding of the film becomes tight, but winding slack can be prevented by guiding both end edges of the film by both the guide inclined surface 58L3 of the flange portion 51L3 and the guide inclined surface 58L2 of the flange portion 51L2. There is an advantage.

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

Next, the basic concept of the film winding method according to the present invention will be described by taking as an example the case where several kinds of the reel members 50A to 50L are applied to the multistage winding system as described above .

19 to 24 are views showing the basic concept of the film winding method of the present invention in a state in which the film is wound by the reel member described above , in (a) a left side view and (b) a front view. .
Fig.25 (a) is a left view which shows the reference example of a film container, FIG.25 (b) is a front view which shows the film container.

As shown in FIG. 17, first, the reel member 11 on which the film is wound is mounted on the feeding device 10, and, for example, after the above-described reel member 50 </ b> A is mounted on the winding device 20, the moving plate of the winding device 20. The flange side 51A on the 44th side (the rightmost side in FIG. 8) and the right side flange part 13 of the delivery device 10 (hereinafter referred to as “right flange part 13a”) are arranged on the same plane. The reel member 50A on the winding side is positioned with respect to the reel member 11.

  Next, the film 2 drawn out from the reel member 11 on the feeding 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. 1A, the flange portion 51A of the reel member 50A is arranged in order from the right one, the first flange portion 51A1, the second flange portion 51A2, and the third flange portion 51A. The flange portion 51A3 and the fourth flange portion 53A4, and the winding shaft portion 52A of the reel member 50A between the first and second flange portions 51A1 and 51A2 is the first winding shaft portion 52A1. A portion between the second and third flange portions 51A2 and 51A3 is a second winding shaft portion 52A2, and a portion between the third and fourth flange portions 51A3 and 51A4 is a third winding shaft portion 52A3. And

And according to the command from the control part 60 mentioned above, while operating the winding motor 32C and starting the rotation of the winding shaft 31, counting of the number of pulses of the winding motor 32C is started.
As a result, the reel member 50A winds around the first winding shaft portion 52A1 while the film 2 to which a load is applied by the delivery device 10 is stretched (see FIG. 19).

20 (a) and 20 (b), after the first winding shaft portion 52A1 of the reel member 50A has finished winding the adhesive film 2, the control unit 60 is a second flange portion 51A2 where the winding portion 2b of the release film 2a where the release-side release film 2a and the roll-side roll-like film 2 are in contact with each other is counted by counting the number of pulses of the take-up motor 32c. When it is determined that the coil has entered the guide groove 53A, the operation of the winding motor 32c is stopped.

As shown in FIG. 21 (a) (b), by a command from the controller 60, rotates the drive shaft 41 by operating the slide motor 43b by a predetermined number of pulses. As a result, the reel member 50A moves along the winding shaft 31 shown in FIG. 17 until the second flange portion 51A2 reaches a considerable distance beyond the position of the right flange portion 13a on the delivery side. In this case, the release film 2a on the delivery side is twisted with respect to the roll-shaped film 2 on the take-up side, so that the release film 2a protrudes from the guide groove 53A of the second flange portion 51A2 and the third flange portion. Approach 51A3.

As shown in FIG. 22 (a) (b), in this state, by rotating the reel member 50A again, the second flange portion 51A2 is hooked release film 2a by guide edge 54A.
Thereafter, as shown in FIGS. 23 (a) and 23 (b) , the reel member 50A winds the release film 2a hooked by the second flange portion 51A2 around the second winding shaft portion 52A2 as it rotates. However, after a while, the feeding of the release film 2a is completed and the next adhesive film 2 is sent, so that the film 2 is wound up.

  On the other hand, the control unit 60 operates the slide motor 43b to return the reel member 50A until the second flange portion 51A2 is arranged on the same plane as the right flange portion 13a on the delivery side.

Accordingly, as shown in FIGS. 24A and 24B , the reel member 50A winds up the film 2 from the feeding side in parallel with the second winding shaft portion 52A2.
Hereinafter, the winding process as described above is also performed on the third winding shaft portion 52A3 of the reel member 50A.

And as shown to Fig.25 (a) (b) , the film container 70A gives the part of the adhesive film 2 and the peeling film 2a from the sending side by giving the above-mentioned winding method to the reel member 50A. For a series of films 2 that are alternately sent to the part, the part of the adhesive film 2 is rolled to each take-up shaft part 52A in a state where the part of the release film 2a is drawn from the flange part 51A to the take-up shaft part 52A. It is rolled up in

27 to 30 are views showing a reference example of the film winding method of the present invention in a state in which the film is wound by the reel member described above .
In the winding method of the film, reel member conjugate 60K of the aforementioned reel member 50K is more binding (hereinafter, simply referred to as "reel member 50K") but, this winding method itself is described above The operation of the reel member 50K having a shape different from that of the reel member 50A will be mainly described below, without being different from the winding method using the reel member 50A.
27, 29, and 30 correspond to FIGS. 22 (a), 23 (a), and 24 (a), respectively.

  As shown in FIG. 27, after the film 2 has been wound around the one winding shaft portion 52K, the reel member 50K itself is slid and rotated in a state where the film 2 reaches the one guide groove 53K. Thereby, the film 2 contacts the guide edge 54K in a state of straddling 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 guide edge 54K is directed toward the first locking groove 57K1, while the roll-shaped film The part 2d loosened from 2 moves in the direction toward the second locking groove 57K2.

  And as shown in FIG. 29, the film 2 is hooked over the edge part of the two flange parts 51K in the state which contact | abutted to the bottom of the 2nd locking groove 57K2, and fell in the 1st locking groove 57K1.

  Thereafter, as shown in FIG. 30, the film 2 is wound around the next winding shaft portion 52K while being kept in tension between the first and second locking grooves 57K1 and 57K2.

On the other hand, in this reference example , from the viewpoint of protecting the film from being broken when the film is drawn using any one of the reel members 50A to 50L described above , the winding shaft portion 52 that has finished winding the film. It is also possible to interpose at least one take-up shaft portion 52 not used between the take-up shaft portion 52 and the next take-up shaft portion 52 to take up the film. As a result, the film between the flange portion 51 for drawing out from the take-up shaft portion 52 that has finished winding the film and the flange portion 51 for winding the film around the take-up shaft portion 52 to take up the film is wound. The film is drawn at a gentle angle as compared with the case where the film is continuously wound around all the take-up shaft portions 52.

However, such a film winding method is preferably applied to the above-described reel member 50F configured from the same point of view. In this case, the film is a curved portion in the guide groove 53F of the flange portion 51F. The winding shaft portion 52F is placed in the guide groove 53F in the other adjacent flange portion 51F, and then wound around the next winding shaft portion 52F.

Here, FIG. 26 is a front view showing another reference example of the film container, as shown in FIG. 2 6, the film container 70B is Lille member conjugate 60F reel member 50F has multiple binding And the so-called one-time film winding method described above.

On the other hand, in the film winding method according to the embodiment of the present invention , as in the case described above, it is a viewpoint that the film is smoothly routed so as not to be broken. 12 (a) and 12 (b), in addition to the concept of adding a space for routing between the winding shafts on the sending side and the receiving side, and in addition, from the viewpoint of uniform weight balance It is preferable to use the reel member 50L. In this case, it is necessary to shift the timing of drawing the film, that is, the timing of sliding the winding shaft portion 52L by 90 degrees.

In the film winding method of another reference example , when the reel member 50A is applied to the multistage winding system 1 in the same manner as described above , the adhesive film 2 is wound around the first winding shaft 52A1. in stage, when the winding portion 2b of the transmitting side of the release film 2a is approaching the guide edge 54A of the second flange portion 51 A2, it is also possible to stop the rotation of the reel member 50A. Then, the release film 2a is hooked on the guide edge 54A of the second flange 51A2 while moving the reel member 50A in the axial direction. Subsequent processing is the same as in the reference example .

Furthermore, as a film winding method of another reference example , when any one of the above-described reel members 50B, 50C, and 50E is applied to the multistage winding system 1, compared with the case where the reel member 50A having the above basic configuration is applied. Thus, the shapes and sizes of the guide grooves 53B, 53C, and 53E are different. Therefore, here, it is necessary to change the timing of stopping the rotation of the reel member 50, but when the adhesive film 2 has been wound around the first winding shaft 52, the release film 2 a is attached to the second flange portion 51. The guide groove 53 is passed through the second take-up shaft portion 52 and then wound while being hooked by the guide edge 54, or the release film 2a is hooked by the guide edge 54 of the second flange portion 51. In the point which winds after moving to the 2nd winding axial part 52, it is the same as that of the said reference example .

Furthermore, when the above-described reel member 50D is applied to the multistage winding system 1 as a film winding method of another reference example , the release film 2a is passed around the engaging protrusion 56D of each flange portion 51D, The point of hooking at the guide edge 54D is the same as in the above reference example , but here, the guide edge of the engaging protrusion 56D is slid after the release film 2a is slid at the outer peripheral edge as the flanges 51D rotate. Since it can be hooked to 54D, the width of the timing for stopping the rotation of the reel member 50D may be expanded as compared with the reference example .

In addition, in the film winding method of the above reference example , the reel member 50 is stopped from rotating when the reel member 50 is moved in the axial direction. However, when the reel member 50 is wound under certain conditions. You may continue to rotate while decelerating from the speed of.

  In this case, the rotation speed of the reel member 50 is determined so as to ensure that the release film passes through the guide groove 53 of each flange portion 51 and that the release film 2 a is hooked on the guide edge 54 of each flange portion 51. There must be.

In addition, when any of the above-described reel members 50G and 50H is used as a film winding method of another reference example , after the film has been wound on one winding shaft portion 52, the film is flanged. 51, it is locked in the vicinity of the take-up shaft portion 52 by dropping into the locking groove 57 along the guide edge 54.

  In this case, with respect to the reel member 50G, as the reel member 50G rotates, the film is blocked by the retaining portion 57G3, thereby restricting the movement in the locking hole 57G2, and changing the posture in the locking hole 57G2. However, it winds around the winding shaft portion 52G in a state of being in contact with the edge portion of the locking hole 57G2 while being in tension.

  As for the reel member 50H, the film is fixed by being pinched by the bottom portion of the locking groove 57H as the reel member 50H rotates, and the film is wound while maintaining a tensioned state from the fixed portion. It winds around the shaft 52H.

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 are automatically flanged 51 when the film is wound in a multi-stage shape. in addition to be used to lock, the locking groove 57 of these, only the step of winding the film automatically performed to lock when the film to the flange portion 51 performs work to route the film manually Also used for.

  However, when the film is manually routed, the guide groove 53 provided in the flange portion 51 does not require the original function of automatically passing the film, and an operator can take up the leading edge of the film, for example. It is only required as a work hole, such as when affixing to the shaft portion 52 or when a film is inserted into the locking groove 57, and the locking groove 57 alone is sufficient without providing the guide groove 53.

Therefore, in this specification , 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 allowing the film to pass through the flange portion 51. For example, for the reel members 50F, 50G, and 50H, it is possible to provide only the locking groove 57 as the “guide groove” without providing the guide groove 53, and for 50K, the engagement including the shape of the guide groove 53 is possible. The stop groove 57 can be provided as a “guide groove”.

As described above, according to the present embodiment (or the reference example) , after winding the adhesive film on the winding shaft portion 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 after that, it is possible to smoothly start the winding of the film at the next winding shaft portion 52, so that the adhesive is applied to the long film from the inside of the film. It becomes possible to wind in a multistage shape while suppressing the diameter to a level that does not protrude.

In carrying out the full Irumu winding method that written, by using the reel member 50 described above, the elongated been film be wound in the multi-stage becomes more effective.

For example, the Rukoto provided a guide groove 53 in the flange 51, to the next winding spool 52 by passing one of the take-up shaft 52 in the guide groove 53 a step with a film take-up is finished the film it is possible to smoothly move, by hooking the film at the edges of the draft in the groove 53 (guide edge), also by hooking while locking the film with engagement groove 57, the next winding spool 52 The film can be wound around without loosening.

In particular, the points where the guide groove 53 provided in each flange 51, the winding shaft portion 52 and the advantage that the film so as not to protrude from the outer peripheral portion can be wound, the draft in the groove 53 of the flange portions 51 by extending to the vicinity of, also, by extending the engagement groove to the vicinity of the winding shaft portion, a film required to routed from one winding spool 52 to the next winding spool 52 (release film ) Has the advantage that the length is short.

Further, the Rukoto provided an engaging projection 56 in the flange portions 51, a film that can smoothly move from one winding spool 52 to the next winding spool 52, with the engaging projection 56 Film There is an advantage that a wide range of timings for performing these operations can be set.

Further , by connecting the reel members 50 to each other in the axial direction, it is possible to appropriately cope with the problem by increasing or decreasing the number of connections of the reel members 50 according to the degree of lengthening of the film.

Furthermore, by the respective guide grooves 53 or each engagement projection 56 is arranged in the same position on the circumference of the flange portion 51, when the hooking when and films for moving the film in the axial direction, the flange portions 51 Can be done at the same timing.

Further, by making the portion through the film in the guide groove 53 on which thick degree corresponding to the thickness of the flange portion 51 in a curved surface, thereby preventing the film break it in routing the film.

  In particular, with respect to such a reel member 50, it is possible to more effectively prevent the film from being broken by using a so-called one-time film winding method.

Furthermore, by locking the automatic flange 51 provided a film engaging groove 57 on the guide edge 54 of the draft in the groove 53 can be prevented so as not film loosen when routing the film.

In particular, not only to lock the film portion wound around the winding shaft portion 52, also the film already wound outer portion Ri by that engaged, thereby preventing loosening of the more effectively the film.

However, even with the reel members 50A to 50E shown in FIGS. 1 to 7, the film can be prevented from loosening by being wound around the winding shaft 52 while the film is hooked on the corner or bottom of the guide groove 53. However, in this case, a certain amount of tension must be continuously applied to the film so that the film does not move from the hooked portion of the guide groove 53, while the reel members 50F to 50F shown in FIGS. In the case of 50K, once the film is locked by the locking groove 57, the tension applied to the film can be reduced to the minimum necessary size, and there is an advantage that it is suitable for winding a thin film.

Further, according to the reel members 50H and 50K shown in FIG. 10 and FIG. 11, the center of gravity of the flange portion 51 itself is on the take-up shaft portion 52. Since the member 50 can be rotated with a uniform rotational moment, the film can be wound evenly while applying the minimum necessary tension to the film.

  Further, since 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 portion 52 as a whole, there are various delivery forms at the time of shipment. Can have a width.

Furthermore, according to the reel member 50L of the present embodiment shown in FIGS. 12 (a) and 12 (b), the uniform balance of the weight of the reel member 50L is achieved, so that a long film is always wound with a uniform rotational moment. In addition, it is possible to wind up a long film without causing folding by guiding the film smoothly while guiding it in a spiral shape. No) A film container 70C containing a film can be provided.

  In particular, in the case of this embodiment, by increasing the number of winding shaft portions 52L and flange portions 51L for each unit number n determined from the point of weight balance, a multi-stage shape is maintained while maintaining a uniform weight balance. The length of the film wound up can be further increased.

  For example, the length of the film that can be wound using the reel member 50L is set such that when a film of 50 meters is wound on one winding shaft portion 52L, an integral multiple N is added to the unit configuration number n (= 4). Multiply to 200 * N meters.
