Abstract

PURPOSE:To eliminate unevenness on the end face of a wound-up sheet roll by removing a swinging arm from a mechanism for supporting a core and for separating it from a touch roller, forming a core supporting body and a space adjusting base in a vibration resistant structure, and fixedly providing said touch roller. CONSTITUTION:By bonding the cut end of each divided sheet to each core C, as the operation of a core driving mechanism is started, a sheet roller R on the outer periphery of the core C is gradually increased in its diameter, and a required contacting pressure is given to between the sheet roll R and a fixed touch roller 2 in accordance with the driving force, by a contacting pressure adding mechanism 25. And, by giving the command of a control device to a servo motor, the core C, together with a core supporting table 10 and a space adjusting base 13, is continuously backed by means of a driving mechanism 16. Then, the core C is supported, and separated from the touch roller 2. Thus, by removing a supporting arm structure from a mechanism, and by forming the core supporting table 10, space adjusting base 13, and touch roller into a vibration resistant structure which suppresses the vibration of the core C, the vibration of the core C is eliminated, stabilizing contacting force.

Description

[Detailed Description of the Invention] <Industrial Application Field> This invention divides a strip-shaped sheet of plastic film, paper, metal foil, etc. into multiple strips using a slitter, distributes them to both sides, and supports them in a fixed position to prevent movement. The present invention relates to a slitter ribbon that winds a belt-shaped sheet divided into nine parts through a touch roller, around a core supported by a pair of left and right core supports provided correspondingly.

<Conventional technology> The dividing and winding device for belt-shaped sheets is called a Nutitter Rewind, which uses a slitter to divide the belt-shaped sheets and distribute them to both sides.

A typical type is such that as each winding is wound on each winding core on both sides via a touch roller, the support position of each winding is swung away from the supporting position of each winding.

Recently, thin and slippery plastic films are increasingly being used for strip sheets, and in order to wind them at high speed, small and light touch rollers are applied to each sheet roll that is distributed and wound.

There are products that provide more precise control of the winding contact pressure. For example, in Japanese Patent Publication No. 45-20644 ``Rewinding Machine'', thin touch rollers are applied to the lower sides of each of the left and right sheet rolls that are distributed and wound to detect roll thickening. Sheet roll (
In other words, the winding core) is supported at both ends and IL! Each support arm that is driven by J rotation is rotatably supported by bearings at both ends.

The support arm is slidably engaged with a common shaft for supporting support arms provided to extend in the width direction of the belt-shaped sheet, and is swingable by rotation of this common shaft. These support arms mechanically maintain an inclination angle,
Each time the touch roller detects a certain amount of roll thickness, it gradually raises the slanted arm.

In addition, as disclosed in Japanese Patent Publication No. 55-293, a large number of sheet rolls each supported by an independent support arm are supported in a fixed position so as not to move by a contact pressure applying mechanism provided on each support arm. The sheet roll and/or the touch roller are pressed into contact with a single common touch roller.

winding the slit strip through said touch roller, each support arm relative to said common touch roller;
One common support base is pivoted so that it can swing back and forth within a small angular range from the vertical support position, and the swinging displacement of each support arm in response to an increase in the winding diameter of each sheet roll is representative or, Based on the average detection value, the common support base is automatically controlled in a horizontal direction from the common touch roller so that each sheet roll support arm as a whole always maintains a substantially vertical support state. A sheet dividing take-up device is known in which the sheet is retracted.

Note that, as disclosed in the first embodiment of Japanese Patent Publication No. 57-28658, a sheet dividing and winding device that divides a wide belt-like sheet with a slitter and winds the divided belt-like sheets around each core is not suitable. However, a touch roller is attached to the upper end of a beam that is swingably supported around one point and extends vertically, and the winding shaft and While the sheet roll is being held and being wound, a fluid pressure cylinder is applied to the beam.
1: Apply force and adjust the contact pressure between the touch roller and the sheet roll to a constant level, and as the sheet roll winding diameter increases, the motor drives the screw shaft engaged with the holder to separate the holder and the winding shaft. A winding device is already known in which the belt-shaped sheet is moved horizontally backward from the touch roller and the belt-like sheet is wound around a first winding shaft while keeping the touch roller at a substantially constant position.

<Problems to be Solved by the Invention> Even with each type of two-way winding device, for example, if a branutic film with a smooth surface and easy to stretch is wound at high speed, 9 rolls-1.
Scattered sheets: The edges of the coils are uneven and cracked. In extreme cases, the split sheets may shift sideways during one winding process, leading to work stoppages.

It was believed that this was caused by the side-slipping phenomenon of the rolled sheet, and that air was drawn into the sheet layer with poor air permeability, resulting in a decrease in the coefficient of friction between the sheets. Therefore, by pressing a touch roller with a required contact pressure against the outer periphery of the sheet roll being wound up to adjust the amount of air that is wound in one roll, the sheet is prevented from shifting laterally.

However, recently 1, for example, when a highly slippery material such as a polyester film whose surface has been treated to have a mirror finish is wound up in parts at high speed, no matter how the contact pressure of the touch roller is controlled, the contact pressure However, no matter how the sheet feeding tension to the winding position is controlled, the above-mentioned lateral shift phenomenon cannot be prevented.

Conventionally, tension, contact pressure, and supply tension were controlled on the assumption that vibration was zero, but as winding speeds have increased, ultra-thin materials, and highly elastic and slippery materials have been wound to a large diameter. become,
In this case, no matter how accurately the above-mentioned control is carried out, it is very difficult to obtain a wound product with good winding quality, and the current situation is that the winding speed is as low as possible and the winding is performed with a small diameter.

The biggest cause of this is the vibration of the winding mechanism, and since control is performed on the assumption that there is no vibration, we have determined that this is not a good thing, and eliminated the causes of vibration as much as possible, increasing tension and contact pressure.

This invention enables effective use of supply tension control.

Even if the causes of this vibration are eliminated, the minimum movement needed to take up nine winds cannot be avoided, so the configuration of the present invention eliminates these causes as much as possible. Furthermore, look at this +14 formation from the second perspective.

It incorporates ideas to improve operability, which is another problem.

In addition, when winding a wide sheet band by slitting it, winding it immediately after slitting is the most stable way to wind it and does not cause an imbalance in the quality of each rolled product. When winding with
A device that moves the sheet roll without moving the touch roller is suitable. As a means for releasing the sheet roll, a type in which the first roll shaft arm is rotated to swing away from the touch roller according to the thickness of the roll is generally used.

However, with this oscillating separation type, the higher the speed, the more likely it is that vibrations will occur. We have developed a device that eliminates as much as possible the elements that cause vibration.

This requires separating either the sheet roll or the touch roller, or both, depending on the thickness of the sheet roll. In addition, contact pressure control must be performed.Secondly, the configuration must be such that either the sheet roll or the touch roller can be finely adjusted. It is best to fix the problem of vibration firmly if possible, but 1 This is something that cannot be discussed, so I would like to avoid vibration as much as possible. Therefore, since sheet rolls are heavy, the 9-roll core support should be sturdy and solid, and the core support on the sheet roll side is equipped with a moving mechanism for separation due to thickening of the roll and fine adjustment of contact pressure control. In this way,
We have found that it is best to fix the touch roller to prevent vibration.

In addition, for example, when winding a film that is easy to stretch, in order to control the supply tension to restore the elongation of one winding length i' + il, it is necessary to slightly change the speed of the touch roller and use a fixed touch roller, especially a common touch roller. For example, it has the advantage of being structurally very cylindrical.

<1! +]Means for solving the problem> As a result of researching the mysterious lateral shear phenomenon, which is the problem 1111 mentioned above, the present inventor found that lateral shear begins to occur when the device is operated at high speed. They discovered that the main cause was vibration of the sheet roll due to high-speed operation, and not the winding itself.Furthermore, in order to obtain such high-quality rolled products, nine different types of control were carried out, but these main factors Control works accurately and is effective when there is no vibration in the device. However, at present, this vibration is not considered, and everything is controlled on the assumption that the vibration is zero.

However, in reality, the speed is increased, and the winding arm, which is structurally prone to vibration, is made into a rotating type, so if you slow down the speed of one revolution, you may be able to create a winding arm that does not cause winding misalignment, but If you raise it, it will cause misalignment. This is a problem before we even discuss the winding quality.

So, what causes this vibration that has a big impact on the winding quality? After checking various sources of this vibration, we found out.
In addition to being structurally susceptible to vibration, first of all, vibration is caused by the rotation of the winding core shaft.

fa) The core shaft is supported eccentrically.

(b) Support F+ of the winding core is eccentric.

(e) Deformation of winding and unbalance due to uneven thickness Since the vibrations caused by (a) to (e) above cannot be zero, the higher the speed, the greater the vibrations due to eccentricity and unbalance. Furthermore.

Although the winding arm rotates due to the thickening of the roll, the vibration of the winding arm is - for example, 15 microns as a result of an experiment.
It was confirmed that the diameter was as high as 35 microns. This amount of vibration has an adverse effect on the contact pressure control of the sheet band wound nine times.

Conventionally, when performing contact pressure control, which is an important control element related to winding quality, vibrations have been ignored and contact pressure control has been performed on the assumption that there is no vibration. This may be able to control the contact pressure depending on conditions such as thickness, but the recent trend is to wind the Gokuran sheet band with a large diameter, making it no longer important for conditions that require winding at high speeds. .

The invention of the present application focuses on the vibrations that have a significant effect on the winding quality and takes into consideration thorough measures to eliminate the vibrations.

It was confirmed through experiments that no matter how accurate contact pressure control is performed, the cause of winding misalignment is vibration, and thorough efforts were made to eliminate this vibration. It goes without saying that the film path may be from above or from below.

While talking about the specific structure, if we dig deeper into the problem with the step, we will be able to precisely machine the parallelism of the guide mechanism 9 interval adjustment table 1 winding core support with the assembly to prevent any play. By guaranteeing that there is no vibration, the cause of vibration is further eliminated, and since it only moves linearly in one direction, it is the best measure against vibration.

Furthermore, since there is a tendency to slit a wide raw material and roll it into a large diameter roll, the two-point sliding support structure causes deflection.
This can cause vibrations, so we prevent vibrations by using a full-surface or multi-point sliding support structure and supporting it so that it can move linearly in one direction.In addition, it has a low center of gravity and is supported on the most vibration-resistant ground, reducing weight. Vibration was prevented by making it heavier by filling it with concrete.

In addition, the belt-shaped sheet has some thickness unevenness, and if it is rolled up, for example, in thousands of layers, the sheet roll will no longer be a perfect circle.

If the contact pressure is maintained properly, the touch roller has the ability to keep the sheet roll perfectly round to some extent, but the rigidity of the entire support arm that supports the second winding core and the separation mechanism that separates the winding core from the touch roller is important. If the number of turns is small and the core of the first turn is likely to change, the sheet roll will begin to lose its perfect circle, the sheet roll will vibrate, and the contact pressure will become unstable, causing the seal l-(+-) to become a perfect circle. It becomes difficult to maintain.

Therefore, when the sheet roll is rotated at high speed, the force applied to the sheet roll from the touch roller changes in small increments, and the rotational balance of the sheet roll itself becomes poor, causing the sheet roll to vibrate together with the support arm supporting the second core. , the contact pressure of the touch roller also changes in a wave-like manner, causing the sheet to slide sideways.

This is the result of the inventor's efforts to elucidate the cause of this phenomenon.

In order to prevent the phenomenon of lateral slippage, this was the main role of conventional belt-shaped sheet winding devices. The method disclosed in Japanese Patent Publication No. 45-20644 in which the winding core is supported by a supporting arm that swings at a single point in the center is completely abolished. In the conventional swing type core support arm, which changes the inclination angle as the roll thickens, the vibration of the sheet roll that causes the support arm to swing is entirely absorbed by the drive mechanism (which is used to turn the core 241) from the touch roller. Even if the swing angle changes slightly, it will cause a large change in the core support part at the tip of the support arm, and since the center of swing does not move, as the roll thickens, the touch roller's seal (IJ-ru) will be pressed. Direction and touch 1-Contact between the roller and the sheet roll In order to avoid causing too much difference in the JIE direction number and to sufficiently separate the core from the touch roller, the length of the core support must be made longer. As a result, the two-wound core support has a long and flexible structure, which makes it impossible to prevent the vibration of the sheet roll.

Furthermore, in order to move the first core support away from the touch roller by swinging, the touch roller is applied (11) even if the direction is constant.
Due to the thickening of the sheet roll, the direction connecting the touch roller and the center of the sheet roll changes, and correction is required for precise contact pressure control. and.

Since each touch roller located inside the core support must be replaced through the nine core supports, replacement or maintenance of the touch rollers is troublesome.

Further, due to the structure, preparation work for new winding cannot be performed until after the sheet roll has been moved to another position, and the stop time of the slitter rewinding increases to 1 k.

Incidentally, regarding this point, the same can be said about the prior art disclosed in Japanese Patent Publication No. 55-293. In the prior art disclosed in Japanese Patent Publication No. 55-293, the contact pressure must be adjusted on the side of the core support that swings and supports a very heavy sheet roll. It is easily affected by inertia, etc., and since the support arm of the first roll core is pivotally supported on a support stand, even slight deformation of the sheet roll during winding may cause the support arm to swing and cause the sheet to Rolls tend to vibrate.

Furthermore, there is also another conventional example,
The winding device disclosed in Publication No. 8 is used for winding tape of a constant width, and does not have the function of adjusting the distance between the pair of left and right holding bodies that support the two winding shafts. Unlike slitter rewinding, which requires changing the channel division width, it is virtually impossible to apply this method to slitter rewinding, and vibrations are not taken into consideration.

The outline of this invention, which was created by solving all of the above problems, is as follows.

The strip-shaped sheet divided by the slitter is distributed to the winding positions on both sides, and wound onto the core at each winding position via a touch roller that is supported in a fixed position so as not to move.As the roll thickens, the core is removed from the touch roller. In the sheet dividing and winding device that separates the sheet, a plurality of guide mechanisms are fixed on a base or the ground at right angles to the width direction of the strip sheet, and the sheet is supported and guided by the guide mechanisms to linearly move in one direction at right angles to the width direction of the strip sheet. a plurality of pairs of space adjustment tables on each of the two sides that are supported and guided by the space adjustment tables, capable of horizontal linear movement in one direction in the width direction of the band-shaped sheet, and further capable of horizontal linear movement in the width direction of the band-shaped sheet; A winding core support body having a sheet winding core support part that supports the winding core, and the space adjustment table linearly moving in one direction on a guide mechanism;

To adjust the contact pressure, the core support is placed against the interval adjustment table.
The belt-shaped sheet moves straight in the width direction/Q4 in one direction,
The guide mechanism is a high-speed machine characterized by being equipped with a guide mechanism 9 interval adjustment table and a drive mechanism for moving each of the core supports so as to be able to move horizontally linearly in one direction perpendicular to the width direction of the strip sheet. Sheet division winding device.

Function> This invention solves the phenomenon of sideways slipping of a strip-shaped sheet that occurs during high-speed winding, and eliminates the conventional support for the winding core using a swinging arm in order to suppress the vibration of the sheet roll that occurs during winding, which is the cause of this. , developed a new method for supporting and moving the core of the antigen structure.

In other words, the core support of the present invention does not move the core away from the touch roller by swinging itself as in the conventional case, but merely restrains and supports the core and places it on the spacing adjustment table in the sheet width direction. Although it is equipped with a support and guide mechanism that is guided so as to be able to move laterally only linearly in one direction at right angles to the figure, it is integrally supported.

Furthermore, the interval adjustment table slides and positions the 9-roll core support only when the sheet division width changes;
While controlling the contact pressure integrally with each core support on one side by a core support drive mechanism, each core is moved little by little on the guide mechanism as the core becomes thicker.

This interval adjustment table is engaged with the guide mechanism so that the guide machine 11 can move in this guide direction, but is restrained from moving in other directions.

A is integrated with the core support of ``-'' to form an antigenic structure that suppresses the vibration of the first core.

Furthermore, since the core support of the 1-spacing adjustment table -I has 11 sliding positions, the support position of the winding core support can be easily changed, and the 1-spacing adjustment table moves away from the fixed touch roller at the winding position. It is possible to create a space where workers can enter.

The core support and the spacing adjustment table are integrated to support the core, and linearly move the core away from the fixed touch roller in the lateral direction. and.

Since the rocking force acting on the core support is supported by the guide mechanism, 2
The lateral force acting on the winding core is not magnified.

Fine adjustment of the core support for contact pressure control is performed using a low friction cylinder or a bellows cylinder, so the touch roller can be firmly fixed.

Therefore, it is possible to increase the weight of the 9-spacing adjustment table, etc., which has rigidity in the lateral direction. 1. For example, the sheet roll is filled with concrete or the like to prevent vibration from occurring in the sheet roll.

Practical example 1st. Figure 2 shows an embodiment of this invention.

FIG. 1 is an explanatory elevational view of a sheet dividing and winding device according to the present invention.

FIG. 2 is an explanatory diagram of the same plane.

The wide sheet S travels on a sheet running path above the nine winding work spaces, passes through a group of rollers, reaches a grooved roller 1, and is divided into a plurality of strips by a slitter K. And the sheet divided into one.

It is distributed from the grooved roller 1 via the touch roller 2, which is supported in a fixed position so as not to move, and is parallel to the touch roller 2.

It was supported by the tips of a pair of core supports 10. The sheet roll R is wound around each core C.

The right half of FIG. 1 shows a state in which the sheet roll R is wound up, and the left half shows a state in which the rolled-up sheet roll R is passed to the delivery mechanism and the core support 10 is retreated. In addition, in the left half of FIG. 1, a winding is shown in which the winding core support 10 is moved in 1) 11 (rightward movement in the figure) and the supported winding core C is brought into contact with the touch roller 2 that is rotatably supported in a fixed position. The state at the start of the process is shown by the chain line. The position of the winding core C, which indicates the winding position, moves from the chain line position at the start of winding, drawn in the left half of FIG. 1, to the solid line position at the completion of one winding. A touch roller 2 in which the first roll core C is gradually rotatably supported at a fixed position as the sheet roll R becomes thicker.
It is moving away from.

The contact pressure is controlled by a low-friction cylinder 25 that performs fine adjustment of the first core support. Alternatively, the touch roller can be firmly fixed and vibration-free since the horizontal linear movement is guided without play by adjusting it with a peroflator, cylinder, etc. Further, although using a conventional spring as a means for applying a pressing force to a fixed touch roller is inferior in terms of automatic control, it goes without saying that this is still good.

Note that FIG. 2 shows a cross section taken along cutting line a-a in FIG. 2.
.

Along the front and rear winding positions, space adjustment tables 13 are provided horizontally in the sheet width direction, and the first roll core support 10 is supported by these space adjustment tables 13''.

In this case, the 1-spacing adjustment table 13 has a dovetail-shaped protrusion 13a extending in the sheet width direction on its upper part, and the winding core support 10, the base of which is slidably engaged with the dovetail-shaped protrusion 13a, is attached to the spacing adjustment table. ,
It is guided so as to be movable in the sheet width direction and in a direction perpendicular to the sheet width direction for contact pressure control. Even if the sheet dividing position by the slitter K changes, the stand 2 of the 1-roll core support 10
7 can be slid on the one-interval adjustment table I3 to a new winding position corresponding to the dividing position, and can be fixed with a clamp 15 provided at the base thereof.

Furthermore, the 9-roll core support moves in the sheet width direction on the 9-spacing adjustment table 13; ii) It moves laterally only linearly in one direction perpendicular to the sheet width direction on the 9-spacing adjustment table 13; It is provided with a supporting guide groove 28 in which it can be guided. The mechanism for moving these is the base 11 and the interval adjustment table 13, which will be described below. A mechanism similar to the moving mechanism of the guide mechanism 12 may be used. Further, one or both of each pair of core supports is provided with a core drive groove (not shown) that centrally drives the core C in order to wind up the divided sheet with a required tension. In order to enable the 9-winding core C to separate from the fixed touch roller 2, the 1-interval adjustment table 13 is set at a winding position 1ζ before and after the 9-winding core C.
They were placed at 31:0 in the width direction of the sheet.

A guide mechanism 12 such as a rail 12a that extends horizontally at right angles to the width direction of the seat and is fixed to the base 11'' supports and guides the seat so that it can move linearly only in one direction without wobbling in other directions. be done. Basically, this causes vibration in the guide mechanism's seat L/12a. A movable movable body (fitting member) 14a, l that is fitted and guided so as to prevent play in the vertical, horizontal, and other directions.
The interval adjustment table 13 is fixed to the ``-'' of the leg stand 14 fixed to t. And the base 11 and the interval adjustment table 13.13
In between, there is provided a drive mechanism 16 for driving the interval adjustment tables 13 and 13 on both sides of the 9 in one direction in a symmetrical direction. In this case, the drive mechanism 16 mainly operates the rail 12 for each interval adjustment table on one side.
The ball screw shaft 1 has a small rotational resistance with no substantial backlash and is screwed into the threaded part 16b because it is fixed to the nine-spacing adjustment table 13, which is arranged in two places on the left and right in parallel with the direction a.
6a1 During winding, a servo motor 16c drives the ball screw shaft 16a at low speed, a motor 16d rotatable in both forward and reverse directions drives the ball screw shaft 16a at high speed, and the rotation of these motors 16c and 16d is transmitted to the ball screw shaft 16a. It consists of a differential gear mechanism 16e, a transmission shaft 16f, and a bevel gear mechanism 16g. And balls 4 on the left and right
・The screw 16a is synchronously driven and the 9-interval adjustment table 131 winding core C
can approach and leave in parallel with the fixed touch roller 2. Furthermore, since the ball screw shaft 16a tries to prevent displacement other than the displacement of the interval adjustment table 13 due to its own rotation, even if a large force is applied to the interval adjustment table 13 from the outside.

As a result, the distance adjustment table 13 is not easily displaced.

It should be noted that a drive mechanism for separating the first winding core C from the fixed touch IJ-ra (1) may also use a motor-driven rack, pinion mechanism, fluid 11, cylinder, etc.
．． Further, the arrangement of the ball-ray axis 16a is not limited to two locations, and one motor may also serve as the motors 16c and 16d. It is also possible to use other screw shafts instead of the ball screw shaft.

In addition, if it is necessary to mechanically further ensure the parallel movement of the 1-interval adjustment table, a known diagonal movement mechanism can be used as an auxiliary mechanism in addition to adjusting the f+'i degree of the guide mechanism to 1-gero. .

These structures must firmly support the first core C and suppress the vibrations to such an extent that even when the sheet roll R grows eccentrically and rotates at high speed, the vibrations do not occur in the sheet. Therefore, the guide mechanism 12 on the floor or base is fixed, and the rails 12a are restrained from moving vertically and horizontally.
of the movable body 14a (see Fig. 3) that is engaged with the
14. Interval adjustment table 13 for supports fixed thereon. Each core support 10, which is slidably engaged with this and fixed by tightening the clamp 15 during one winding, is located between the end portion supporting the core and the retaining portion of the nine-spacing adjustment table 13. , 1) For contact pressure control, 11 is provided with a sliding part in the rear direction, but has an integrated structure that does not include a 2 rotating part,
It has an antigenic structure that cannot receive vibrations, that is, even if a force that tries to cause vibration is applied to the winding core, it has sufficient rigidity and rigidity to prevent it from being synchronized (for example, by assembling reinforcing bars and filling the core). They are connected to each other without any looseness, creating a short profile that is directly connected to the floor or base.

Further, in the contact sensor, the force of the sheet 1 noll is pushed onto the touch roller using a fluid pressure cylinder such as a low friction cylinder or other driving device 11 by adjusting the force. In this case, the 1st roll core support is placed on the edge of the 1st interval adjustment table, and as the sheet roll becomes thicker, it is displaced relative to the interval adjustment table, so the 1st roll core support is placed almost at a constant position on the interval adjustment table. In order to maintain the position within the range, the displacement of the 9-volume core support is detected and controlled by feeding it back to the drive mechanism that moves the 9-spacing adjustment table backward. What controls the magnitude of the contact force is a contact pressure control device that adjusts the driving force of the low friction cylinder 25.

With the above configuration, a low-friction cylinder is provided for each divided sheet roll, so
Appropriate contact pressure control is possible even for differences in the winding diameter of each sea 1-I knot due to 1'/mm unevenness of the sheet band.

In addition, the leg stands 14 on both sides on which the 1-spacing adjustment table 13 is mounted protrude long to the sides, increasing the area of engagement with the guide machine RF912, thereby increasing the stability of the 9-spacing adjustment table 13. . A work floor plate 17 is installed on the upper surface between the legs 14 and 14 to make it easier to work on both sides of the winding position. In addition.

In the embodiment, the footrests 14 are provided at three locations in total, at both ends and in the middle.

Enhances antigen function. Furthermore, by providing multiple leg bases 14 and guide mechanisms in the middle, and increasing the number of locations to an infinite number, it becomes an integrated structure that supports the entire surface, which further suppresses the deflection of the interval adjustment base and allows the antigen function to be better exerted. can.

Note that a groove 13b is provided in the center of the dovetail-shaped protrusion 13a on the negative side of the space adjustment table, and a groove 13b is provided over the entire length of the space adjustment table. It contains a screw shaft 19 that can be rotated in reverse.

On the other hand, each winding core support 10 is slidably engaged with the spacing adjustment table.
The retaining portions 10a each holding a locking/disengaging mechanism that can be engaged and disengaged from the screw shaft 19 as indicated in - are provided in the groove 13b, and the screw shaft 19 can be rotated in the normal direction.

During reverse rotation, it is possible to move the 1-interval adjustment table to a predetermined position in a short time by operating the engagement and disengagement mechanism to engage and disengage the screw shaft.

- On the other hand, fixed touch rollers corresponding to each winding core C at one winding position on both sides are provided in the center of this device.

Note that the touch roller is a fixed position touch roller common to one side.

A similar effect can be obtained even if a separate fixed position touch roller is used.

The separation drive of the winding core C during winding is controlled by a first winding core support displacement detecting device (not shown) and winding: 1. Detection device ffj
(not shown), the sheet roll R is pressed against the fixed touch roller 2 with the required contact pressure by a 9-core reciprocating low-friction cylinder or a velophram cylinder, and the 2nd core C is separated. This is performed by a control device that instructs the drive mechanism of the core support to drive.

Note that the control device is not limited to this, and any known device may be used depending on the type of drive groove, etc.

- The one-way core support 10 is shown as having a U-shape and having a space below the sheet roll for receiving the delivery mechanism at the sheet roll receiving position.

Note that the shape of the first roll core support is not limited to the U-shape, but may be variously changed such as an inverted-shape, a C-shape, a columnar ring without a pocket, and a support for a sheet roll.

The operating procedure for this device is briefly explained as shown on the left side of Figure 1.

Volume 1. For each pair of core supports 10 and 10, which have passed the removed sheet roll R to the unloading device and retreated to the solid line position, a new core C is first supported, and then one sheet roll is unloaded and driven. Rotate the motor 16c of the mechanism at high speed to advance the core support 10.10 toward the fixed touch roller 2 of all ff1L, and move the core C to the fixed touch roller 2 as shown by the chain line in the left half of Figure 1. bring into contact. In addition, the rail 12a of the guide mechanism is provided with a movable movable body (fitting member) 14a that covers the rail 12a of the guide mechanism and is guided by fitting in order to prevent vibrations in the downward, left-right, and other directions. An interval adjustment table 13 is fixed via a leg stand 14 fixed to.

When the cut ends of each divided sheet are glued to each new core C and the core driver groove (not shown) is started to operate, the sheet roll R on the outer periphery of the first core C gradually becomes thicker. The friction cylinder 25 applies the required contact pressure between the sheet roll R and the fixed touch +1-ra 2 according to its driving force, and also gives the command from the control device described above to the servo motor 16c to drive the drive mechanism 16. By this, the core support 101 and the interval adjustment table 13 as well as the core C are continuously retracted. It goes without saying that if the contact pressure is 0 (applied continuously by the friction cylinder), the separation of the 1-interval adjustment table 3 may be intermittently.

According to this invention, both ends of the winding core C are firmly restrained and supported by the support mechanism of the antigen (14-structure core with sufficient weight and rigidity). The distance adjustment table 13 is firmly fixed to the dovetail-shaped protrusion 13a on two sides with a clamp 15, and furthermore, this distance adjustment table 13 is connected to the screw shaft of each drive device 16 via a leg table 14. 16a, and the female thread 16b, the first core support 101 interval adjustment table 13. The footrest 14. Since the guide mechanism 12 has an antigenic structure and suppresses the vibration of the first roll core C, the sheet roll R cannot generate vibrations that would cause the sheet to shift laterally.

Further, when the sheet division width changes and the position of the slitter is changed, the clamps 15 of each core support 10 are loosened and the 9-interval adjustment table 13J- is slid to the corresponding position.

Note that a well-known positioning drive mechanism may be used in place of manual labor to move each core support to a desired position.

Although one embodiment has been described above, the present invention can be varied and applied in various ways depending on the implementation conditions and using well-known techniques of the designer.

For example, in the embodiments described above. The fitting member 14a may be fixed to the floor or base η:2 and a rail fixed to a two-distance adjustment table may be guided by the fitting member, or the fitting member may be suspended from the floor or base and firmly supported. 9. Guide the 1-interval adjustment table directly with a rail without using a 9-leg platform. 1. Use a commercially available linear motion bearing (commonly known as 'J Nearway).

It is possible to provide guidance between the guide surface of the rail and the fitting member via a rolling element such as a wheel, or to use the 11 surface of the base as a sliding gap and directly engage the lower surface of the interval adjustment table in sliding engagement with this. From here,
The distance adjustment table may be supported and guided by a guide mechanism.

The method for attaching the winding support to the interval adjustment table is not limited to the above-mentioned embodiments, such as using commercially available linear motion bearings and sliding engagement. Other clamp mechanisms may be used, but are not limited to those in which the winding support engages with the side of the interval adjustment table.

In addition, by fixing both J:I5 parts of the stay part hand 426 to a pair of left and right winding core supports (, 11 bodies),
When the left and right winding core supports are connected and integrated into one (114 structure), the winding core separates from the touch roller.

It is possible to ensure a 1'-distance of the winding core with respect to the touch roller.

The left and right winding core supports can be individually separated from the touch roller.

If the left and right sides are not integrated, it is not always possible to maintain parallelism between the first winding core and the touch roller.

In addition, in the example, the 9-spacing adjustment table is supported by a set of three rails provided at both ends and the center of the 9-spacing adjustment table, but the guide mechanism, such as the number and position of the rails, can adjust the spacing. The position that supports the table and its sheet dividing winding device are of the type that centrally drives nine cores, and the type that uses a combination of center drive and surface drive using touch rollers.

Surface-driven type 1 or the like may be adopted depending on the conditions.

Basically, if you try to eliminate vibration as much as possible, it is understandable that there are various ways to deal with it.

-1- In the embodiment described above, the first core is separated from the touch roller in the horizontal direction, but it may be separated in a direction close to horizontal. Further, the nine-volume core support may be movably supported by a plurality of interval adjustment tables.

<Effects of the Invention> The present invention uses a sheet dividing device to divide a plastic film whose surface is extremely slippery and wind it at high speed. -Researched and clarified the cause of the unevenness of the end faces of the wheels.

That is, even if an attempt is made to properly adjust the contact pressure between the touch roller and the sheet roll to prevent sheet roll deformation and edge irregularities.

The rigidity of the core support and its approach/separation mechanism as a whole is small.

During winding, the deformation of the sheet roll due to the thickness of the belt, etc. cannot be suppressed only by the contact control between the fixed touch fJ-ra and the sheet roll, and the deformed sheet) IJ- The sheet roll vibrates due to the simultaneous rotation of the rollers, which causes sideways slipping of the wound sheet.Furthermore, when the touch roller is oscillated to control the contact pressure, vibration occurs in the touch roller. I saw something.

As a countermeasure, the supporting means for the first winding core oscillates as the winding thickens, and since it is difficult to control vibrations with the conventional winding arm, we have developed a new winding core supporting means that moves linearly as the winding thickens to maintain a fixed touch. We developed an anti-roller plate (made of 11 yen) that separates from the roller, and we also used a touch 1J-ra that was firmly fixed to move the core support horizontally to control the contact pressure and further prevent vibrations. .it is.

Although it is equipped with a support guide mechanism that guides all the core supports so that they can move laterally only linearly in one direction perpendicular to the sheet width direction with respect to the 1-interval adjustment table during winding. As the whole is integrated, it moves along the guide mechanism without loosening or floating as the winding progresses.
With its large mass and rigidity, it moves while suppressing the vibration of the winding core, that is, the vibration of the sheet roll.

In addition, when changing the position of 1 division of the band-shaped sheet division width, the 9-roll core support.

It is possible to easily change the winding core support position by sliding the 4 adjustment stands 11i.

In order to prevent vibration with conventional equipment, the rotation of the base shaft of the take-up arm, which has a sheet roll attached to the tip that is the source of the vibration, is stopped.

Even with the "lever" principle, there was only an extremely disadvantageous method.

This invention eliminates the troublesome work of changing the core support position of the core supporter, which is often necessary, in the step of winding up each sheet roll by maintaining a simple core support mechanism. All of the supporting core supports are incorporated into a large antigen structure on each side, which increases the ground-breaking vibration-damping power to ensure steady straight movement.

This equipment successfully prevents sideways displacement of the A-sheet due to vibration and unevenness of the sheet roll end face, and also achieves extremely good operability and productivity, reducing the cost of equipment.
