Further, preferably, the film automatic winding device 2 may have an air bleeding mechanism. By doing in this way, the problem that air enters between films 10 can be prevented.

Moreover, the film automatic winding apparatus 2 of this embodiment uses the air releasing mechanism as the touch roller 23. As shown in FIG. In this way, the touch roller 23 also functions as an air bleed mechanism, and it is not necessary to provide an air bleed mechanism separately. Therefore, the apparatus can be miniaturized.

The air bleeding mechanism is not limited to the above mechanism, and any mechanism may be used as long as the bleeding air is possible. For example, the near winding system which winds up close, without touching a roller, the touch winding system which fully contacts like the touch roller 23, etc. are mentioned.

If there is no problem in the characteristics of the film 10, it is preferable to select a touch winding method having the touch roller 23 as an effective means of preventing the air from being rolled up. The touch roller 23 also has a function of pressing the film in addition to degassing, and is particularly preferable because it can prevent the film 10 from being shifted during cutting.

<Guide Cutter>

Fig. 5 is a schematic view of the guide attachment cutter of the automatic film winding apparatus according to the embodiment of the present invention, (a) shows a front view, and (b) shows a C-C cross-sectional view.

In FIG. 5, the guide attachment cutter 24 includes a cutting blade 241, a rodless cylinder 242, a support member 243, a guide rod 244, an arm 245, a rotation shaft 246, and a driving arm. 247 is provided.

The rotation shaft 246 is rotatably supported by the bearing plate 201 opposite to both ends, and the driving arm 247 is fixed to the tip of the right side. The tip of the drive arm 247 is connected to a rotating air cylinder (not shown).

The pair of arms 245 is a plate member having a bent end, and the bottom side is fixed to the rotation shaft 246 in an opposing state. At the tip of the arm 245, a rodless cylinder 242 is mounted via a support member. In addition, a connecting member is attached to the tip of each arm 245 via the supporting member. Two guide rods 244 are attached to each connecting member in a state in which they face each other with a predetermined gap.

In addition, the cutting blade 241 is attached to the rodless cylinder 242 via the supporting member 243. The cutting blade 241 can cut the film 10 having the maximum width dimension L. FIG. In addition, the cutting blade 241 moves a predetermined gap between the two guide rods 244. That is, when the arm 245 rotates, the two guide rods 244 abut the film 10, and by this abutment, an appropriate tension is applied to the film 10. The cutting blade 241 cuts the film 10 given proper tension. By doing in this way, the problem of being bent and cut | disconnected by the entry | exit side or the exit side of the cutting blade 241 can be avoided, and linear cutting can be performed. In addition, the problem that the resist chip is attached can be avoided.

The guide attachment cutter 24 cuts the film 10 caught between the first winding shaft 21 and the second winding shaft 22 between the first winding shaft 21 and the second winding shaft 22. .

As described above, the guide attachment cutter 24 has a pair of arms 245 rotatably supported, and the distance between the pair of arms is L ₀ (see FIG. 5).

Here, the film attachment roller 25 has a pair of arms 253 rotatably supported, and the maximum external dimensions of the arms 253 including the air cylinder 254 are L ₁ (see FIG. 3). ). And L ₀ > L ₁ . Therefore, between the pair of arms 245 of the guide attachment cutter 24, the pair of arms 253 of the film attachment roller 25 enter.

Further, the distance between the arms 253 is L ₂ (see FIG. 3), and the distance between the pair of arms 232 supporting the touch roller 23 so as to be rotatable is the distance L ₂ between the arms 253. Shorter than Thus, the pair of arms 232 of the touch roller 23 enter between the pair of arms 253 (see FIG. 4). That is, according to the said structure, since the arm 245, 253, 232 does not interfere with the film automatic winding apparatus 2 of this embodiment, an apparatus can be miniaturized.

<Winding positioning means>

6 is a schematic view of the core positioning means of the film automatic winding apparatus according to one embodiment of the present invention, (a) shows a front view, and (b) shows a D-D cross-sectional view.

In FIG. 6, the core positioning means 29 includes a stopper 291, a knob 292, a slide rod 293, a connecting plate 294 and a bearing 295. In FIG.

The stopper 291 has a substantially rectangular cylindrical shape and is slidably mounted with respect to the slide rod 293. In addition, the stopper 291 penetrates the knob 292 provided with the male screw protruding from the lower portion. The stopper 291 is fixed to the slide rod 293 when the knob 292 is tightened. When the knob 292 is loosened, the stopper 291 becomes slidable.

Both ends of the slide bar 293 are connected to the bearing 295 via the connecting plate 294. The pair of bearings 295 are each screwed to the bearing plate 201. The bearing 295 has a rotation angle of about 180 degrees, and can rotate in this range. The worker rotates the slide bar 293 between the standby position (the inclined position on the front side lower side) and the positioning position (the back side inclined position).

The stopper 291 of the core positioning means 29 generally avoids the problem of contacting the wound film 10 in the standby position. Moreover, when positioning the core 12, it is rotated to a positioning position, and the cross section of the core 12 abuts with the stopper 291, and the core 12 can be positioned. There is also, in this embodiment, is fixed to the L ₃ is the distance from the abutment surface, the axis center of each stopper 291 (see Fig. 2).

By doing in this way, the core 12 can be positioned at a short time degree while high precision, and productivity and quality (center winding precision) can be improved. Moreover, by making the core positioning means 29 into the above structure, it is easy to use and the structure is simplified. Therefore, the manufacturing cost can be reduced.

In addition, in this embodiment, although it is set as the structure which an operator installs the core 12, it is not limited to this. For example, the winding core 12 may be configured to automatically install the winding core 12 at a predetermined position on the winding shafts 21 and 22 by a winding positioning mechanism (not shown).

<Film carrying roller>

Moreover, what is necessary is just to have the film conveyance roller which supplies the film 10 to the winding shafts 21 and 22 preferably. In this way, the film 10 can be conveyed smoothly.

As shown in FIG. 1, the film automatic winding apparatus 2 of this embodiment is equipped with the 1st film conveying roller 27 and the 2nd film conveying roller 28 about each pair of turrets 20, respectively. Doing. The first film conveying roller 27 and the second film conveying roller 28 supply the film 10 to the first winding shaft 21 or the second winding shaft 22.

The journal diameter of the film conveying rollers 27 and 28 shall be 10-25 mm. This journal diameter is the shaft diameter of a roller, and 10-25 mm is optimal in order to reduce rotational resistance with a bearing. If the journal diameter is too thick, the rotational resistance increases, making the preroller difficult to rotate, and too thin, the roller lacks strength. The more preferable range is about 10-15 mm, and 15 mm was selected this time. However, it is not limited to this range. In the measurement of the journal diameter, calipers are generally used.

In addition, the angle (film sandwich angle) of the contact surface of a film conveyance roller and a film should just be 90-160 degrees. Specifically, as shown in FIG. 7, the pinching angle of the last two rollers (film conveying rollers 27 and 28) is preferably in the range of 90 to 160 ° as viewed at least from the winding shaft. The reason is that if the included angle is too small, the roller does not rotate, causing meandering or damaging the film. In addition, when the included angle is too large, the tension of the film is cut off, and thus, the support tension of the wound product cannot be controlled, and a failure such as winding becomes hard occurs.

Moreover, Preferably, the film contact surfaces of the film conveying rollers 27 and 28 may be a porous material or a non-adhesive material. The reason why the film contact surface is made of a porous material is that a cross-section winding shift of the wound product (winding step due to air being rolled up between the film 10 and the film conveying rollers 27 and 28 and the film is shifted in the lateral direction) Defects) can be effectively prevented. Examples of the porous material include foamed materials, and among these, rubber materials are preferred for reasons such as not damaging the film or durability. Moreover, when using an adhesive material for the said film contact surface, it is preferable to use a non-tacky rubber material so that it may not adversely affect the holding tension (winding hardness) of a product. Although largely affected by the characteristics of the product to be wound, a rubber material having a coefficient of friction of 0.7 to 0.8 and a rubber hardness of 40 to 80 ° is more preferable.

<2. Nippers ＞

In the film automatic winding apparatus 2 of this embodiment, as the support means which supports the stopped film 10, the nipper 26 is provided below the 1st film conveyance roller 27. As shown in FIG.

This nipper 26 is a metal rod whose upper surface consists of resin, rubber | gum, etc., and is about the same length as the 1st film conveyance roller 27. As shown in FIG. The nipper 26 reciprocates in an up-down direction by reciprocating drive means, such as an air cylinder. When the nippers 26 are moved upwards, the stopped film 10 is pressed against the first film conveying rollers 27 and supported so as not to move.

By providing the nipper 26 in this way, the axial shift of the stopped film 10 is prevented effectively, and generation | occurrence | production of bad start is suppressed more reliably. Moreover, by setting it as the said structure, the film 10 can be reliably supported. In addition, since the structure is simple, the manufacturing cost can be reduced.

Next, the operation and effect of the film automatic winding apparatus 2 having the above-described configuration will be described with reference to the drawings.

8 is a schematic cross-sectional view of the side direction of the main portion for explaining the operation of the film automatic winding apparatus according to the embodiment of the present invention.

As shown in FIG. 8 (a), when the film 10 is wound around the winding core 12 of the first winding shaft 21 by a predetermined amount, the first winding shaft 21 is rotated. The rotation is stopped (step S1).

At this time, the first winding shaft 21 and the second winding shaft 22 are stopped rotating, the touch roller 23 is being pressed, the film attachment roller 25, the guide attachment cutter 24, and the nipper 26. Is waiting, and the core positioning means 29 is at the positioning position. In addition, the first winding shaft 21 is at the film winding position, and the second winding shaft 22 is at the evacuation position.

Moreover, when the film 10 is wound, the touch roller 23 presses the film 10 wound by the core 12. As a result, the touch roller 23 functions as an air bleeding mechanism between the films 10 to be wound. In addition, even if the rotation of the first winding shaft 21 stops, the touch roller 23 maintains the pressing state.

In addition, when the film 10 is wound, it is preferable that the contact angle (pinching angle) of the conveyance rollers 27 and 28 and the film 10 shall be 90 degrees-160 degrees. If the included angle is smaller than 90 °, the rotation of the conveying roller will not be sufficient, which will cause the film to meander, and if larger than 160 °, the tension to the film will be too strong, making it difficult to adjust the tension on the winding shaft. .

In addition, when the film 10 is wound, the pressure control mechanism (expansion packing 211) adjusts the pressure with respect to the core 12. Thereby, tension suitable for film winding is ensured.

Next, as shown to FIG. 8 (b), the film 10 caught by the 1st film conveying roller 27 is supported by the nipper 26, Then, the touch roller 23 rotates upwards, In addition, the turret 20 is rotated 180 ° so that the film 10 is caught by the second winding shaft 22 (step S2).

At this time, the first winding shaft 21 moves to the evacuation position, and the second winding shaft 22 moves to the film winding position.

At this time, the first winding shaft 21 and the second winding shaft 22 are stopped rotating, the nipper 26 is being supported, the touch roller 23, the film attachment roller 25, and the guide attachment cutter 24. And the core positioning means 29 are waiting.

Moreover, since the nipper 26 supports the film 10, generation | occurrence | production of bad start can be suppressed more reliably.

In addition, before the turret 20 rotates, the operator applies an adhesive to a part of the surface of the core 12 of the second winding shaft 22, and the core 12 is moved to the core positioning means 29. Positioning is carried out on the 2nd winding-up shaft 22 using this, and the core positioning means 29 is rotated to a standby position.

In addition, when the turret 20 rotates, the core 12 of the first winding shaft 21 is returned to the counterclockwise rotation direction. However, the film 10 is in a taut state by the support torque of the expansion packing 211. That is, a tension suitable for cutting the film is ensured.

Next, as shown in FIG.8 (c), the touch roller 23 rotates downwards, presses the film 10 to the core 12 of the 2nd winding shaft 22, and then guides cutter (24) rotates downward, and cuts the film 10 in a straight line between the 1st winding shaft 21 and the 2nd winding shaft 22 (step S3).

At this time, the first winding shaft 21 and the second winding shaft 22 are stopped rotating, the nipper 26 is being supported, the touch roller 23 is being pressed, the guide attachment cutter 24 is being cut, The film attachment roller 25 and the core positioning means 29 are in the air.

In addition, in this embodiment, when the film 10 is cut | disconnected, although the 2nd winding-up shaft 22 stopped rotation, it is not limited to this. For example, when cutting the film 10, the second winding shaft 22 may be rotated at a speed of 15 m / min or less (a low speed of rotation corresponding to a speed of 15 m / min or less). . In this way, the tension of the film cut surface can be ensured.

Next, as shown in FIG.8 (d), the guide attachment cutter 24 rotates upwards, the film attachment roller 25 rotates downwards, and it cut | disconnected in the downstream position of the touch roller 23. Then, as shown to FIG. The film 10 is pressed to the core 12 of the film automatic winding device 22 (step S4).

At this time, the first winding shaft 21 and the second winding shaft 22 are stopped rotating, the nipper 26 is being supported, the touch roller 23 is being pressed, the film attachment roller 25 is being pressed, The guided cutter 24 and the core positioning means 29 are waiting.

Next, as shown in FIG. 8E, the film attachment roller 25 is further rotated downward, and the film 10 is wound around the core 12 while the film 10 is pressed against the core 12. It winds up and moves to the front-end | tip part of the cut film 10 (step S5).

At this time, the first winding shaft 21 and the second winding shaft 22 are stopped rotating, the nipper 26 is being supported, the touch roller 23 is being pressed, the film attachment roller 25 is being pressed, The guided cutter 24 and the core positioning means 29 are waiting.

In addition, the front-end | tip part of the cut | disconnected film 10 is a range from the cutting | disconnection position of the film 10 to several mm below several tens of mm normally.

In addition, in this embodiment, as shown in FIG. 9, the roller 251 shown by the dotted line of the film attachment roller 25 abuts the film 10 inclined from the front side upper side, and wound up the film 10 ( 12) (step S4). And in the said step S5, the roller 251 moves about 100 degrees in the state which pressed the film 10 to the core 12, and maintains the pressed state (this roller 251 is shown by the solid line). ). Thereby, the film 10 between the roller 231 and the roller 251 shown by the dotted line closely adheres to the core 12, and in particular, the film 10 between the roller 251 of the dotted line and the roller 251 of the solid line. ) Is forcibly brought into close contact with the core 12 by the roller 251. That is, the looseness of the film 10 between the pressing position by the roller 231 of the touch roller 23 and the front end of the cut film 10 is effectively suppressed. Thereby, the film 10 can be wound in the state which contact | adhered to the predetermined position of the core. Therefore, defects, such as a bad start, wrinkles which arise at the time of film winding, and fold | fold of a film part, can be cut down reasonably.

In addition, the distance (angle) which the roller 251 moves in the state which crimped the film 10 to the core 12 is not limited to said about 100 degrees, About 60 according to the kind (adhesive force) of a film, etc. It can be set within the range of ° to about 130 °.

Moreover, Preferably, as shown in FIG. 9, the angle (winding angle) which the film 10 winds up to the core 12 should just be in the range of 30 degrees-90 degrees, More preferably, within the said range A larger angle may be sufficient. By doing in this way, the distance until the front-end | tip of the cut | disconnected film 10 is inserted between the film 10 and the core 12 which are supplied is shortened. Thereby, the reliability of winding quality (especially folding of a film corner part etc.) can be improved.

In addition, a winding angle means the angle from the immediately upper direction of the core 12 to the position which the film 10 supplied and the core 12 contact.

Next, as shown to FIG. 8 (f), the 2nd winding-up shaft 22 which is a friction axis | shaft is predetermined | prescribed in the state which the film attachment roller 25 pressed the front-end | tip part of the film 10 to the core 12. Next, as shown to FIG. The low-speed rotation is performed in the winding direction with the loosening removal torque (step S6).

At this time, the first winding shaft 21 is stopped rotating, the second winding shaft 22 is rotating at low speed, the nipper 26 is being supported, the touch roller 23 is being pressed, and the film attachment roller 25 The pressure is applied and the guide attachment cutter 24 and the core positioning means 29 are waiting.

Further, the looseness can be completely removed by the low speed rotation with the predetermined loosening torque. That is, for example, some looseness may remain between the roller 231 of the touch roller 23 and the roller 251 of the film attachment roller 25, as shown in FIG. . Even in this case, without winding the film 10 on the upstream side of the touch roller 23, the core 12 rotates by a small angle (X point → X ₁ point) according to the amount of loosening. Remove looseness completely. Thereby, defects, such as bad start, wrinkles which arise at the time of film winding, and fold | fold of a film corner part, can be rationally avoided, and the highly reliable winding technique can be established.

In addition, the low speed rotation of the 2nd winding shaft 22 in step S6 is the rotation speed corresponding to the speed of 50% or less of the film winding speed normally. For example, when the film winding speed is 50 m / min, the rotation speed of the 2nd winding shaft 22 is the low speed rotation speed corresponding to the winding speed of 25 m / min or less.

Next, as shown to FIG. 8 (g), the nipper 26 moves downward and the support of the film 10 with respect to the 1st film conveying roller 27 is released, and then the 2nd winding shaft ( 22 rotates at a low speed in the winding direction with a predetermined winding torque, the film 10 is wound around the winding core 12 of the second winding shaft 22, and the tip of the cut film 10 is the film 10. When approaching the mutually overlapping position, the touch roller 23 and the film attachment roller 25 are rotated upwards, and the pressing force with respect to the film 10 is released (step S7).

At this time, the first winding shaft 21 is stopped rotating, the second winding shaft 22 is rotating at low speed, the nipper 26, the touch roller 23, the film attachment roller 25, and the guide attachment cutter 24. And the center of gravity positioning means 29 are waiting. In addition, the 2nd winding shaft 22 normally rotates by the said low rotation further half rotation-several times, and the film 10 mutually overlaps reliably by this.

In addition, the low speed rotation of the 2nd winding shaft 22 in step S7 is the rotation speed corresponding to the speed of 50% or less of the film winding speed normally. For example, when the film winding speed is 50 m / min, the rotation speed of the 2nd winding shaft 22 is the low speed rotation speed corresponding to the winding speed of 25 m / min or less.

Next, as shown in FIG. 8 (h), when the front end of the cut film 10 passes through the overlapping positions of the films 10, the touch roller 23 rotates downward again to form the film 10. Is pressed against the winding core 12 of the second winding shaft 22, and the second winding shaft 22 is then rotated in the winding direction with a predetermined winding torque (step S8).

At this time, the first winding shaft 21 is stopped rotating, the second winding shaft 22 is rotating at a predetermined winding speed, the touch roller 23 is being pressed, the nipper 26 and the film attachment roller 25. ), The guide attachment cutter 24 and the core positioning means 29 are waiting.

Next, although not shown, the worker first removes the core 12 in which the film 10 is wound from the first winding shaft 21, and newly inserts the core 12 into the first winding shaft 21. (Step S9).

As explained above, according to the film automatic winding apparatus 2 of this embodiment, the looseness of the film 10 between the pressing position by the touch roller 23 and the cut | disconnected tip part is suppressed effectively. Thereby, the film 10 can be wound in the state which contact | adhered to the predetermined position of the core 12. Therefore, defects such as bad start, wrinkles generated at the time of film winding, and folding of each film portion can be prevented, and the winding quality can be greatly improved.

Further, by rotating the winding shafts 21 and 22 at low speed with the loosening removal torque, some looseness can be removed and the winding quality can be improved.

In addition, the present invention is also effective as the invention of the slit winding system 1. That is, by providing the film automatic winding apparatus 2, quality and productivity can be improved.

Next, one Embodiment of the manufacturing method of a winding film is demonstrated.

First, as shown in FIG. 11, when the film 10 winds a predetermined amount in the core 12 of the 1st winding shaft 21, the 1st winding shaft 21 stops rotation (step S1).

Next, the stopped film 10 is supported by the first film conveying roller 27 by the nipper 26, the touch roller 23 releases the pressing of the film 10, and the turret 20. It rotates by this 180 degree, and the film 10 is caught by the core 12 of the 2nd winding shaft 22 (step S2).

Next, the touch roller 23 presses the film 10 against the core 12 of the second winding shaft 22, and the guide attachment cutter 24 cuts the film 10 (step S3).

Next, the film adhesion roller 25 presses the cut | disconnected film 10 to the core 12 of the 2nd winding shaft 22 in the downstream position of the touch roller 23 (step S4).

Next, it moves to the front-end | tip part of the cut | disconnected film 10, winding the film 10 in the state which the film adhesion roller 25 was pressed (step S5).

Then, the second winding shaft 22, which is the friction shaft, rotates at a low speed in the winding direction with a predetermined loosening torque (step S6).

Next, the nipper 26 releases the support of the film 10, the second winding shaft 22 rotates at a low speed in the winding direction with a predetermined winding torque, and the film 10 is the second winding shaft 22. When the front end of the cut film 10 approaches the overlapping position, the touch roller 23 and the film attachment roller 25 release the pressing force (step S7).

Subsequently, when the front end 10 of the cut film passes the overlapping position, the touch roller 23 presses the film 10 against the winding core 12 of the second winding shaft 22, and the second winding shaft 22. ) Rotates in the winding direction with a predetermined winding torque (step S8).

Then, the core 12 in which the film 10 is wound is first removed from the first winding shaft 21, and the new core 12 is charged into the first winding shaft 21 (step S9).

As explained above, this invention is effective also as a manufacturing method of a winding film, and can improve quality and productivity.

Further, in the slit winding system 1, the film automatic winding device 2, and the method of manufacturing the wound film, the film automatic winding device 2 includes the turret 20, the guide cutter 24, and the nipper. (26) and the core positioning means 29, etc., but the present invention is not limited thereto.

For example, in the film automatic winding apparatus of the present invention, as shown in Fig. 9, one winding shaft 22, a touch roller 23 (roller 231), and a film attachment roller 25 (roller ( 251)) may be provided. That is, the film automatic winding device does not have to include the turret 20, the guide cutter 24, the nipper 26, the core positioning means 29, and the like.

In this case, the worker cuts the film 10 wound around the core 12, removes the wound film 10 and the core 12, installs a new core 12, and replaces the film 10 with a new one. To the core (12). As a result, the film automatic winding apparatus has a structure in which the touch roller 23 and the film attachment roller 25 are separated between the pressing position by the touch roller 23 and the tip of the film 10. Suppresses looseness effectively. That is, since the film 10 can be wound in the state in which the film 10 is in close contact with the predetermined position of the core 12, the winding quality is greatly improved.

In addition, the film automatic winding apparatus of the above simple configuration may be configured to selectively include various functions and structures (for example, an automatic cutter, a plurality of winding mechanisms, a rotating touch roller or a film attachment roller, etc.). good.

In addition, the film automatic winding apparatus of this simple structure is effective also as a manufacturing method of a winding film, and the winding quality improves significantly. Moreover, the manufacturing method of this winding film may have the process of rotating to a winding direction with the torque which removes the looseness of a film, etc.

Although the preferred embodiment of the film automatic winding device, the slit winding system, and the method of manufacturing the wound film of the present invention has been described and described, the present invention is not limited to the above-described embodiment, It goes without saying that changes can be made.

For example, although an adhesive such as glue is used as the holding means for holding the film 10 wound on the core 12 by the film attachment roller 25 on the surface of the core 12, the present invention is not limited thereto. no. For example, depending on the characteristics of the film 10 or the like, adsorption by static electricity, an air spray method, a double-sided tape, or the like may be used. Even in this way, the problem that the front-end | tip of the film 10 peels off from the surface of the core 12 before the films 10 mutually overlap can be reliably avoided.

In addition, as described above, it is not necessary to say semi-automatic using this apparatus, and fully automatic can also be achieved.

Although the present invention provides a film automatic winding device for winding a film, a slit winding system, and a method for producing a wound film, the material and structure of the film are not particularly limited. The material of the film may be, for example, a resin, metal, cloth, paper or the like, or a mixed material thereof. The film may be of a laminated structure in which layers made of different materials are laminated.
