Description

The present invention relates to a method for winding a ribbon and an apparatus for carrying out the method.

More specifically, the present invention relates to an audio cassette, a professional video, a home video, a digital computer tape, a photographic film, a photosensitive film, a plastic film such as a typewriter ribbon, a ribbon such as a paper, and the like.
When performing winding such as coating and curing on the winding device, the thin ribbon that is being wound on one winding core is wound on an empty winding core without stopping its running and winding. The present invention relates to a method for winding a ribbon and an apparatus for carrying out the method, which makes it possible to continue.

[Conventional technology]

The full take-up tube is moved from the take-up position to the preliminary position, and the thin take-up tube is cut between the empty take-up tube and the full take-up tube located at the take-up position. The full take-up tube is continuously moved from the take-up position to the preliminary position and the empty take-up tube located at the take-up position is wound between the full take-up tube and the full take-up tube. In the method of cutting the body and continuing the winding of the ribbon to the empty winding tube,
Conventionally, the method shown in FIGS. 9 and 10 has been adopted.

That is, the rider arm 1 is used as a fulcrum of rotation on the turntable 11.
1a is swingably supported, and a rider roll 2 is rotatably supported on the tip of a rider arm 1. While winding the thin strip F on the winding tube in the winding position, the rider roll 2 supported by the rider arm 1 is brought into contact with the outer surface of the thin strip W wound on the winding tube (Fig. 9). .

When the ribbon W is fully wound, the turntable 11 is rotated around the fulcrum 12.
Turn 180 ° to the position shown in Fig. 10. As shown in FIG. 10, the rider arm 1 and the rider roll 2 are reversed together with the turntable 11 to cut the ribbon F between the winding position and the preliminary position.

[Problems to be solved by the invention]

According to such a conventional method, since the end portion of the thin strip F cut between the winding position and the preliminary position is freely wound up on the fully wound thin strip W, the thin strip F travels. The air A swaying in the direction intersecting the direction and entrained in the full-wound ribbon W is wound around the full-wound ribbon W together with the thin strip F (see the arrow in FIG. 10).

In the conventional device, no particular consideration is given to the contact position of the rider roll 2 with the fully wound ribbon W, and the ribbon F
Since the rider roll 2 presses the thin strip body W after being wound around the circumferential surface of the thin strip body W at a considerable angle,
The air A entrained together with the ribbon F cannot be escaped to the outside anymore even if it is pressed by the rider roll 2, and is entrained in the fully wound ribbon W as it is.

This air entrainment occurs even when the winding speed is low, but it does not pose a problem at a winding speed of 50 to 300 m / min. However, when the winding speed becomes as high as 350 to 500 m / min, the entrainment of air becomes very remarkable.

The air thus wound in the full-wound ribbon W gradually escapes to the outside while being stored in a fully-wound state later, and thus the obtained full-wound ribbon W is obtained. The outer surface of W becomes a messy state after at least some layers of air have been evacuated, and is a defective product due to a problem in the physical properties of the thin strip F and a problem in the shape of the wound full strip W. . For this reason, conventionally, the outermost layer, the gull-up part, is released and discarded.

On the other hand, in JP-A-52-31280, both ends of the core are
It is rotatably clamped by the holding mechanism provided on the multi-spindle turret, and at the first winding position, a sheet-like material having a long length is wound around the core, and then the multi-spindle turret is swung to move to the second winding position. And a winding mechanism for forming a roll-shaped material by fully winding the sheet and a swinging mechanism for rotatably supporting the first and second winding positions. A winding machine including a first touch roller and a second touch roller that can swing in parallel with a core is disclosed.

In the winding machine disclosed in Japanese Patent Laid-Open No. 52-31280, the roll-shaped material at the second winding position is pressed by the second touch roller, and special consideration is given to the contact position. It is possible to prevent the air from being entrained in the fully wound thin strip body W together with the thin strip body F.

However, in the winder disclosed in Japanese Unexamined Patent Publication No. 52-31280, no special consideration is given to the contact of the first touch roller with the core, and the thin strip body is pressed when the first touch roller is pressed. There is a problem that scratches and wrinkles are easily formed on the.

Further, in the winding machine disclosed in Japanese Patent Laid-Open No. 52-31280, the first touch roller is pressed at the first winding position where most of the long sheet is wound around the winding core, while At the 2 winding position, the second touch roller is pressed, and
In the middle of the process, the first and second touch rollers are simultaneously pressed against the fully wound ribbon. As described above,
In the winding machine disclosed in Japanese Patent No. 280, since the first touch roller is switched to the second touch roller during winding, the contact pressure of the thin strip changes during winding and a stable and good winding is achieved. There is a problem that it cannot be taken.

These problems are particularly noticeable in a thin ribbon that has a low winding tension and needs to be wound with a low contact pressure.

[Object of the Invention]

The present invention makes it possible to softly touch the rider roll with an empty winding tube, prevent scratches and wrinkles from entering the thin strip when the rider roll is pressed, and prevent scratches and wrinkles at the start of winding the thin strip. Wrinkles can be prevented, good winding can be performed with a uniform contact pressure from the start of winding to full winding, and at the same time, air entrapment at the completion of winding of the ribbon can be prevented, and the obtained thin An object of the present invention is to provide a method for winding a thin strip and a device for performing the method, which enables the outermost layer of the strip winding body to be used as a good product.

[Means for solving problems]

In the present invention, the above-mentioned object is to move the full-winding tube from the winding position to the preliminary position and to form a thin strip between the empty winding tube and the full-winding tube located at the winding position. In a method of cutting and continuing to wind a ribbon on an empty winding tube, a rider roll is softly pressed against the empty winding tube via the ribbon wound on the empty winding tube. Then, the ribbon was wound on the winding tube while the rider roll was being pressed against the ribbon of the winding tube, and when the winding tube became full, the ribbon was wound on the winding tube. The rider roll is positioned near the virtual contact point where the cut end of the ribbon is separated from the full-roll ribbon or at the outer surface position of the full-roll ribbon on the free end side of the contact point. Winding of the thin strip, characterized by pressing the outer surface position of the fully-wound strip with a roll To achieve by law.

Furthermore, in the present invention, as an apparatus for performing the above method,
A member for moving the take-up tube between the take-up position and the preliminary position, and a member for cutting a thin strip continuous from the full-take-up take-up tube located at the preliminary position to the empty take-up tube located at the take-up position And a rider roll that presses the outer surface of the full-wound ribbon during the winding of the thin strip onto the winding tube and when moving from the winding position to the preliminary position. A member that is rotatably supported between a pair of rider arms that are swingably supported by a main rider arm provided coaxially with the winding tube on the member, and that rotates the rider arm with respect to the main rider arm; A stopper member for controlling the clearance between the rider roll and the take-up tube is included, and the stopper member is composed of a pair of pneumatic cylinders that abut against the pair of rider arms. A speed control valve is connected to the exhaust side of each cylinder, and a common switching valve is connected to the air supply side of each pneumatic cylinder, and 1/2 of the total supporting load of both rider arms is connected to each pneumatic cylinder through the switching valve. A winding device for a thin strip is provided, which is adapted to supply a supporting air pressure.

[Work]

In the present invention, since the rider roll is soft-touched to the empty winding tube via the thin winding body wound on the empty winding pipe, the thin winding body is damaged or wrinkled when the rider roll is pressed. This can prevent scratches and wrinkles at the start of winding the ribbon.

Further, in the method of the present invention, the thin ribbon of the winding tube is constantly pressed by the same rider roll during winding, and a uniform contact pressure is applied to the thin ribbon during winding. ,
Good winding of thin ribbon can be performed.

In addition, in the method of the present invention, the thin ribbon is separated from the fully wound thin ribbon toward the empty winding tube in the vicinity of or outside the virtual contact position, that is, the empty winding tube. The side positions can be pressed by the rider roll, thereby preventing air from being entrained in the fully wound ribbon body together with the ribbon body.

Here, when the position of the downstream side of the contact point, that is, the full-wound ribbon side is pressed by the rider roll, it is within a range of about 150 mm, preferably about 100 mm from the contact point. Within this range, the ribbon can be pressed by the rider roll in a state in which the ribbon is hardly wound, and the air entrained in the fully wound ribbon together with the ribbon can be pushed out by the rider roll to prevent the inclusion. When the rider roll presses the contact point position or the upstream side of the contact point position, that is, the free end side of the ribbon, it is pressed by the rider roll without winding the ribbon at all. Therefore, it is possible to prevent air from being caught in the full-wound ribbon.

As shown in FIG. 9, a conventional rider arm is swingably supported on a rotation fulcrum distant from the axis of the winding tube, and a rider roll is provided at the tip thereof. For this reason, in view of the fact that the contact position of the rider roll is limited in the conventional device, in the device of the present invention, the rider arm is swingably supported on the main rider arm provided coaxially with the winding tube. However, the rider roll is rotatably supported at the tip of the rider arm, so that the rider roll can press the vicinity of the virtual contact point of the fully wound ribbon or the free end side of the contact point. This can prevent wrinkles when the thin ribbon is rolled up.

The output shafts of the servomotors 53a and 53b with reduction gears are directly connected to the rotary shafts 13c and 13d of the winding tubes 13a and 13b, respectively. As a result, the winding tubes 13a and 13b are rotated at a predetermined speed by the servomotors 53a and 53b with reduction gears, respectively.

Referring again to FIG. 1, a reion arm 15 is rotatably supported on a rotation fulcrum 15a on the outside of the turntable 11, and a reion arm 15 is rotatably supported by a fluid pressure cylinder 15b on the tip of the reion arm 15. A main arm 15c is supported, and a raion roll 16 and a winding roll 17 are rotatably supported on the raion main arm 15c.

The structure of the reion arm 15, the reion roll 16, the winding roll 17, and the like is different from that of, for example, JP-A- Since the structure is similar to that disclosed in Japanese Patent Laid-Open No. 62-120996, detailed description will be omitted.

A guide roll 18 is rotatably provided at a position upstream of the reion arm 15.

A cutting arm 19 is rotatably provided at a rotation fulcrum 19a above the reion arm 15, and a pair of rolls 20 and a blade driving device 21 are provided at the tip of the L-shaped cutting arm 19. Has been. The blade driving device 21 moves the blade 22 in a direction orthogonal to the paper surface to cut the ribbon.

The cutting arm 19, the blade driving device 21, and the blade 22 are similar in structure to those disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 62-120996, and a detailed description thereof will be omitted.

In FIGS. 1 and 2, the main rider arms 36a, 3 are attached to the rotary shafts 13c, 13d of the winding tubes 13a, 13b, respectively.
6b and large gears 36c and 36d are rotatably supported by bearings (not shown). Main rider arm 36a, 3
Large gears 36c and 36d are integrally fixed to the 6b as shown in FIG. The above-described turntable 11 has the servomotors 53a and 53b with reduction gears and the servomotors 33a and 33b with reduction gears for arm rotation attached thereto, and the output shafts of the servomotors 33a and 33b with reduction gears are attached. The fixed small gears 33c and 33d mesh with the large gears 36c and 36d.

Therefore, by operating the servomotors 33a, 33b with a reducer, the main rider arms 36a, 36b are rotated around the rotary shafts 13c, 13d of the winding tubes 13a, 13b via the small gears 33c, 33d and the large gears 36c, 36d. It can be rotated.

It should be noted that as the member for rotating the main rider arms 36a, 36b, another drive source, for example, an oscillating hydraulic cylinder or the like may be used.

A pair of rider arms 38a, 38b are swingably attached to the tips of the main rider arms 36a, 36b, respectively. Rider rolls 46a and 46b are rotatably held at the tips of the paired rider arms 38a and 38b. Counterweights 39a and 39b are attached to the rear ends of the rider arms 38a and 38b. Rider arm actuating fluid pressure cylinders 42a, 42b are supported on the pivotal fulcrums 41a, 41b of the main rider arms 38a, 38b, and the tips of their piston rods 42c, 42d are attached to the rider arms 38a via fulcrum pins 43a, 43b. , 38b. Therefore, by operating the cylinders 42a and 42b, the rider arm
The 38a, 38b can be rotated with respect to the main rider arms 36a, 36b.

Further, stopper cylinders 44a and 44b are attached to the main rider arms 36a and 36b (only one is shown in FIG. 7). Rollers 45a and 45b are rotatably supported by piston rods 44c and 44d of the stopper cylinders 44a and 44b, and the rollers 45a and 45b can abut on the rider arms 38a and 38b. In the present embodiment, the stopper cylinders 44a, 44b are provided with elongated holes 44e, 44f, so that
The contact positions of the rollers 45a, 45b and the rider arms 38a, 38b can be easily adjusted.

The main rider arm, the rider arm, the fluid pressure cylinder, and the stopper cylinder of this embodiment are provided on both the left and right sides when viewed in the width direction of the thin strip. As shown in FIG. 8, the stopper cylinders 44a and 44b communicate with the air pressure source via solenoid type switching valves 47a and 47b and speed control valves 48a and 48b.

In the ribbon winding device of the present invention having the above-described structure, the ribbon F is wound on the winding tube 13a supported by the rotating disk 11. That is, the thin strip F passes through the guide roll 18, the reion roll 16, the rider roll 46a, and the winding tube 1
It is wound up on 3a.

The servomotor 33a with a reducer is braked so that the main rider arm 36a does not rotate. The rider arm 38a rotates as the thin strip wound on the winding tube 13a becomes thicker, and the cylinder 42a presses the rider roll 46a with a predetermined pressing force.

Speaking of the rider roll 46b on the side of the empty take-up tube 13b, the servomotor 33b with reduction gear and the fluid pressure cylinder 42b are included.
1 is operated so as to be separated from the winding tube 13b at the center side position of the rotary disk 11 so as not to come into contact with the ribbon when the rotary disk 11 rotates.

In the state shown in FIG. 1, the thin strip is wound on the winding tube 13a. When the thin strip on the winding tube 13a is fully wound, the turntable 11 is rotated around the rotation fulcrum 12. By rotating the turntable 11,
The fully wound winding tube 13a moves to the preliminary position, and the empty winding tube 13b that was in the preliminary position moves to the winding position (see FIG. 3).

During the winding of the ribbon around the winding tube 13a and the rotation of the turntable 11, the rider roll 46a presses the circumferential surface of the winding ribbon 13a in the winding tube 13a that is fully wound.

Thus, during the winding of the thin strip F around the winding tube 13a,
The rider roll 46a is continuously pressed against the outer peripheral surface of the wound thin strip W by the nip pressure, and good winding is performed.

As shown in FIG. 3, the thin strip F extends from the fully wound thin strip W wound on the winding tube 13a through the guide roll 14 between the empty winding tube 13b.

At the position B where the rider roll 46a comes into contact with the outer peripheral surface of the fully wound thin strip W as shown in FIG. Even if the main rider arm 36a is fixed to the turntable 11 when the virtual straight line reaching the guide roll 14 is located closer to the guide roll 14 than the point of contact T, that is, the point where it is separated from the fully wound thin strip 13a. Good. During the rotation of the turntable 11,
By rotating the servomotor 33a with reduction gear,
The main rider arm 36a may be rotated around the rotary shaft 13a of the winding tube 13a to bring the rider roll 46a to a predetermined position near the virtual contact point or on the free end side of the contact point.

By being pressed by the rider roll 46 in such a position, it is possible to prevent the air A from being caught in the fully wound thin strip W. On the other hand, after turning the reion arm 15 and the reion main arm 15c from the position shown by the broken line in FIG. 3 to the position shown by the solid line, the cutting arm 19
Is rotated counterclockwise as shown in FIG. 3, and the thin strip F between the guide roll 14 and the empty winding tube 13b at the winding position is shown.
Is cut with a blade 22. The operation of the cutting arm 19 and the blade 22 is similar to the method disclosed in JP-A-62-120996.

When the ribbon F is cut by the blade 22, the ribbon F starts to be wound around the empty winding tube 13b at the winding position.

The blade arm 19 rotates clockwise and returns to the standby position as shown by the solid line in FIG.

In FIG. 4, the fluid pressure cylinder 42b causes the rider arm 38b on the side of the empty take-up tube 13b to pivot largely from the position shown in FIG. 3 to the position shown in FIG. 4 so that the roller 45b of the stopper cylinder 44b ( 7), the rider roll 46b is stopped with a gap C of about 4 to 10 mm from the peripheral surface of the empty winding tube 13b.

On the other hand, in the fully wound thin strip W, the rider arm 39a is slightly rotated clockwise by the fluid pressure cylinder 42a to bring the rider roll 46a in contact with the fully wound thin strip W as shown in FIG. , Slightly separated from the outer surface of the full-wound ribbon W (4th
The figure is exaggerated). By doing so, after that, when the servomotor with reduction gear 33a and the fluid pressure cylinder 44a are operated to return the rider roll 46 to the standby position as shown in FIG.
Does not contact the fully wound thin strip W, and the fully wound thin strip W is not scratched or streaked by the rider roll.
preferable.

Keep the rider roll 46b from rubbing the surface of the ribbon with a slight gap C between the empty take-up tube 13b and the main rider arm 36b by the servomotor 33b with reduction gear (Fig. 2). Winding tube 13b as shown in Fig. 5
The rider roll 46b is rotated clockwise around the rotation shaft 13d to position the rider roll 46b between the winding tube 13b and the reion roll 16. In this state, the gap C'is 2 to 7 mm due to the thickening of the thin strip on the winding tube.

In this state, the solenoid type switching valve 47b of the stopper cylinder 44b is switched and the air inside the cylinder 44b is controlled by the speed control valve.
By discharging through 48b (see FIG. 8), the rider roll 46b is soft and slowly contacts the ribbon on the empty winding tube 13b as shown in FIG.

As a result, the rider roll 46b exerts a pressing force on the empty winding tube 13b. At this time, the nip pressure of the rider roll 46 generated on the empty winding tube 13b through the thin strip F is 0.7 to 1.5 k.
About g / cm ² is preferable.

Next, the reion main arm 15c of the reion arm 15 is rotated counterclockwise as shown by the chain double-dashed line, and then the reion arm 15 is rotated clockwise to move to the position shown by the solid line in FIG. . Further, the rider roll 46a, which was located on the side of the fully wound ribbon W, operates the fluid pressure cylinder 42a to change the position from the chain line position in FIG. Set to the position not to

The rider roll 46 from the state shown in FIG. 5 to the state shown in FIG.
The method of moving a and 46b to softly contact (soft touch) the thin strip on the winding tube will be further described.

In FIG. 8, the switching valves 47a and 47b are switched, the pressurized fluid (air) is introduced from the pipe P, and the pressurized fluid (air) is withdrawn from the pipe Q. The speed of the fluid flowing out of the pipe Q is controlled by speed control valves 48a and 48b. As a result, the stopper cylinders 44a, 44b
The speed at which the piston retracts is controlled and the rider roll
46a and 46b slowly and softly touch the air core (soft touch).

The amount of protrusion of the left and right pistons, that is, Figs. 4 and 7
It may be difficult to set the amount of the clearance C, which is set to 4 to 10 mm in the drawing, to be completely the same on the left and right sides due to processing errors such as the rider arm, rider roll, and air core.

If the bottom of the rider arm hits the roller of one of the stopper cylinders and the rider arm does not hit the rollers of the other stopper cylinder temporarily, the full load (both rider arms And rider roll load). Normally, the stopper cylinder on one side receives fluid pressure from the pipe Q so as to support 1/2 of the total load, so the piston of the stopper cylinder is slightly retracted. As a result, the other rider arm also immediately contacts the roller of the other stopper cylinder.

Thus, while the main rider arm moves to the fixed position shown in FIGS. 4 to 5, one rider arm serves as the roller of one stopper cylinder and the other rider arm serves as the roller of the other stopper cylinder. Hit

Therefore, the rider roll can touch the empty core in parallel (without a gap on the left and right) through the ribbon, and can be soft-touched.

On the other hand, in the case of simple insertion / removal using the stopper rod, it is difficult to synchronize the insertion / removal of the left and right rods, and even if only one of them is slightly hooked, the rider roll inclines in FIG. If you go to and touch as shown in FIG. 6, the rider roll may tilt and touch the air core. If this happens, the rider roll cannot press the film against the air core. Further, even when touching as shown in FIGS. 5 to 6, if both rods are removed, the rider roll may impact the air core and the soft touch may become difficult. Also, since the time that changes from FIG. 4 to FIG. 5 to FIG. 6 is short, there is a case where the rider roll tilts and hits the empty core when one of the remaining rods is caught and pulled out. .

〔The invention's effect〕

In the present invention, the rider roll can be soft-touched to the empty take-up tube through the thin strip wound on the empty take-up tube, and the thin strip can be scratched or wrinkled when the rider roll is pressed. Can be prevented, and scratches and wrinkles at the start of winding a thin strip can be prevented.

Further, in the method of the present invention, the thin ribbon of the winding tube is constantly pressed by the same rider roll during winding, and a uniform contact pressure is applied to the thin ribbon during winding. ,
Good winding of thin ribbon can be performed.

In the method of the present invention, the thin strip is separated from the fully wound thin strip toward the empty winding tube in the vicinity of or outside the contact point, that is, the empty winding tube side, The position can be pressed by the rider roll, thereby preventing the air from being entrained in the fully wound ribbon together with the ribbon.

Here, when the position of the downstream side of the contact point, that is, the full-wound ribbon side is pressed by the rider roll, it is within a range of about 150 mm, preferably about 100 mm from the contact point. Within this range, the ribbon can be pressed by the rider roll in a state in which the ribbon is hardly wound, and the air entrained in the fully wound ribbon together with the ribbon can be pushed out by the rider roll to prevent the inclusion. When the rider roll presses the contact point position or the upstream side of the contact point position, that is, the free end side of the ribbon, it is pressed by the rider roll without winding the ribbon at all. Therefore, it is possible to prevent air from being caught in the full-wound ribbon.

As shown in FIG. 9, a conventional rider arm is swingably supported on a rotation fulcrum distant from the axis of the winding tube, and a rider roll is provided at the tip thereof. For this reason, in view of the fact that the contact position of the rider roll is limited in the conventional device, in the device of the present invention, the rider arm is swingably supported on the main rider arm provided coaxially with the winding tube. However, the rider roll is rotatably supported at the tip of the rider arm, so that the rider roll can press the vicinity of the virtual contact point of the fully wound ribbon or the free end side of the contact point. This can prevent wrinkles when the thin strip is rolled up.
