Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention decomposes a strip-shaped sheet of a plastic film, paper, metal foil or the like into a plurality of strips by a slitter and distributes the strips to both sides. The present invention relates to a slitter rewinder that winds around a core supported by a pair of left and right core supports provided corresponding to a sheet.

<Prior Art> A strip-shaped sheet winding device is called a slitter rewinder. The strip sheet divided by a slitter and distributed to both sides is wound on each core on both sides via a touch roller.
As the winding weight increases, the supporting position of each winding core is generally swung away from the touch roller all at once.

Recently, strip-shaped sheets are often made of thin and slippery plastic film, which is wound at high speed.
In some cases, a light and small touch roller is applied to each of the sheet rolls that are sorted and rolled up to refine the winding contact pressure control. For example, in Japanese Patent Publication No. 45-20644 “Rewinding Machine”, a thin touch roller is applied to the lower side of each of the left and right sheet rolls that are sorted and wound to detect the winding thickening. Each support arm that supports the sheet roll (that is, the core) at both ends and is driven to rotate, rotatably supports both ends by bearings,
It is slidably engaged with a supporting arm supporting common shaft provided so as to extend in the width direction of the belt-like sheet, and can swing by rotating the common shaft. These supporting arms mechanically maintain the inclination angle, and each time the touch roller detects a certain winding weight, the supporting arms are gradually raised.

Further, as disclosed in JP-B-55-293, a large number of sheet rolls supported by independent supporting arms are supported at fixed positions so as not to move by a contact pressure applying mechanism provided on each supporting arm. Sheet roll or touch roller,
Or, by driving both of them, the slit strip is wound up via the touch roller, and each supporting arm oscillates with respect to the touch roller common to the previous term in a range of a little angular range from the vertical supporting position. It is pivotally supported on one common support table so that the swing displacement of each support arm according to the increase of the winding diameter of each sheet roll is detected representatively or evenly, and each is detected based on the detected value. A sheet split winding device of a type in which the common support base is positively retracted horizontally from the common touch roller by automatic control so that the sheet roll support arm as a whole always maintains a substantially vertical support state. It has been known.

As disclosed in the first embodiment of Japanese Patent Publication No. 57-28658, in a sheet split winding device for winding a wide strip-shaped sheet while slitting the strip-shaped sheet around each winding core while dividing the strip-shaped sheet with a slitter. However, a touch roller is attached to the upper end of a vertically extending beam that is swingably supported around a single point, and a holding shaft that is supported on a frame so as to be horizontally movable via a trolley and While the sheet roll is being held and wound, a pressure is applied to the beam by a fluid pressure cylinder to adjust the contact pressure between the touch roller and the sheet roll to a constant value, and as the sheet roll take-up diameter increases, the motor holds the sheet roll. Drives the screw shaft engaged with to retract the holder and winding shaft from the touch roller in the horizontal direction, and winds the strip-shaped sheet around the winding shaft while keeping the touch roller at a substantially constant position. The taker was already known.

<Problems to be Solved by the Invention> Even in each of the above-described winding devices, when a plastic film having a smooth surface is wound at high speed, the end surface of the wound sheet roll becomes uneven. At times when it is difficult, the work may even stop due to the lateral misalignment of the split sheets that have become thick during winding.

It was understood that this is due to the side slip phenomenon of the rolled-up sheet, which is caused when air is entrained in the sheet layer having poor air permeability and the coefficient of friction between the sheets decreases. Therefore, the touch roller is pressed against the outer circumference of the sheet roll being wound with a required contact pressure to adjust the amount of air to be rolled in, thereby preventing the lateral displacement of the sheet.

However, recently, when a polyester film having a very slippery surface, such as a polyester film having a mirror-finished surface, is wound at high speed in a divided manner, no matter how the contact pressure between the touch roller and the sheet roll is controlled, The lateral deviation phenomenon cannot be prevented by controlling not only the contact pressure but also the winding tension and the sheet supply tension to the winding position.

Conventionally, the winding tension, contact pressure, and supply tension were controlled on the premise that there was no vibration, but it was necessary to increase the winding speed, and an extremely thin sheet, highly elastic and slippery. It has become possible to wind a sheet into a large diameter, and in this case, it is very difficult to obtain a wound product with good winding quality no matter how accurately the above control is performed in the conventional sheet split winding device. The current situation is that the speed is as low as possible and the winding is done with a small diameter. The biggest reason for this is the vibration of the winding mechanism, and the control is performed on the premise that there is no such vibration, so it is determined that it is not good. The cause of the vibration is eliminated as much as possible, and the winding tension, contact pressure, and supply This is an invention that enables effective use of tension control.

Even if the cause of this vibration is eliminated and the cause is eliminated, the minimum movement for winding cannot be avoided. Therefore, the configuration of the present invention is the one that is eliminated as much as possible. Furthermore, from the viewpoint of this mechanism, another problem is taken into consideration to improve operability.

Moreover, when slitting a wide sheet strip and winding it up, winding up immediately after slitting is the most stable state and does not cause imbalance in the quality of each wound product. In the case of winding, the gap between the touch roller and the winding core is gradually widened as the roll becomes thicker, so a device that moves the sheet roll without moving the touch roller is suitable. As a means for escaping the sheet roll, a type is generally used in which the core support arm is swung to swing away from the touch roller in accordance with the winding weight. However, in this type of swinging and separating, vibration is inevitably likely to occur at higher speeds, so first of all,
Instead of this swinging and separating, we have developed a device that separates the core from the touch roller by linear motion and eliminates the factors that cause vibration as much as possible.

This minimizes vibration of the core support. Further, in the structure in which the sheet roll product is taken out between the touch roller and the core support, the core support having an inverted L-shape, a U-shape, a C-shape, etc. as shown in the drawing. In addition, since the guide mechanism for supporting and guiding the core support is firmly provided directly on the base or floor (ground), the seat path is of a type that is lowered from above.
Furthermore, with regard to the take-out of the roll-up product, the conventional lifting device that hangs upward has to be a large-scale device, and there are problems of space and cost. The workability is very poor because the work has to be carried out at the same time. Therefore, in order to solve these problems, a problem of vibration, operability and workability was solved by installing a carry-out device inside the touch roller and the sheet roll. It is designed to support speeding up and automation, solves all the conventional problems, increases productivity several times, and reduces equipment costs, which is a great contribution to the industry.

Furthermore, in the strip winding process for strip-shaped sheets, there is a tendency for small lot production in a lot at present, and the split width of strip-shaped sheets processed by one slitter rewinder varies from wide width to narrow width, and the slit position of slitter and The core support position of the core support is frequently changed. Therefore, in order to improve the productivity, it is required not only to change the slit position but also to change the core support position of the core support in a short time.

In order to wind a very slippery strip-shaped sheet such as a polyester film whose surface is smoothed like a mirror surface at high speed, it is necessary to finely adjust the contact pressure between the sheet roll and the touch roll. It is necessary, and for that reason, an advantageous small diameter and light touch roller is often provided individually for each divided sheet.

In this case, the touch roller also needs to be replaced according to the change in the strip-shaped sheet division width, and it is necessary to easily replace each touch roller in a short time.

Further, in order to improve the productivity, it is necessary to shorten the time for carrying out the rolled-up sheet roll, attaching a new core to the core support, and preparing for the next winding.

<Means for Solving Problems> As a result of researching one inexplicable lateral deviation phenomenon, which is the above-mentioned problem, the present inventor has found that lateral deviation starts to occur when the apparatus is operated at high speed, but the high-speed winding itself causes the problem. However, it was discovered that the main cause was vibration of the sheet roll due to high-speed operation, and in addition, various controls are performed in order to obtain high-quality wound products. Is effective when there is no vibration in the device. However, this vibration is not taken into consideration, and all is controlled under the assumption that the vibration is zero.

However, in reality, since the winding arm, which is faster and structurally susceptible to vibration, is of a swivel type, it may be possible to prevent winding misalignment if the rotation speed is slowed down. If you raise it, winding misalignment will occur. This is a problem before we discuss winding quality.

Then, by checking various sources of this vibration, which has a great influence on the winding quality, it is found that the vibration is structurally prone to occur, and first, the core shaft (A) The support of the winding shaft is eccentric.

(B) The support of the winding core is eccentric.

(C) Deformation and unbalance of winding due to uneven thickness.

Since the vibration due to (a) to (c) above cannot be zero,
The higher the speed, the greater the vibration due to eccentricity and unbalance.

When performing contact pressure control, which is an important control element related to the winding quality, conventionally, vibration was ignored and contact pressure control was performed on the assumption that there was no vibration. This may allow good control of contact pressure depending on conditions such as thickness, but the recent trend is that it cannot be applied to conditions where ultra-thin sheet strips must be wound at a large diameter and wound at high speed. I came.

The invention of the present application is one in which a spot is applied to the vibration that has a great influence on the winding quality to thoroughly eliminate the vibration.

It was confirmed by experiments that the cause of the winding misalignment was vibration, no matter how accurately the contact pressure control was performed. Therefore, we devised a method to eliminate this vibration.

Considering the above things comprehensively, if we try to eliminate this vibration, the structure will be limited. It enables the core support to be separated from the touch roller by a linear motion, and the take-up of the wound roll product is taken out laterally or downward between the take-up arm and the touch roller (taken out obliquely downward). Needless to say, it must be carried out.

Taking a closer look at the problems while discussing the concrete structure based on the above points, the guide mechanism,
By assembling the space adjustment base and the core support to process the parallelism with high accuracy and ensuring that there is no backlash, the cause of vibration is eliminated more and the unidirectional linear movement is the only countermeasure against vibration. Is the best. In addition, since the reverse L-shaped, U-shaped, C-shaped, etc. winding arm is used, neither lifting nor swiveling can be used when taking up the wound product, and in order to solve this, a unloading device (eg, conveyor) The machine is installed between the take-up arm and the touch roller, and the take-out arm and the take-out device work together to carry out batch take-out regardless of the take-up diameter, take-up width and take-up position, enabling full automation. On the other hand, the conventional take-up arm that swivels out and is carried out to the outside is outside the working space side, so a fixed take-out device cannot be installed. Also, take a lot of space,
When operating this take-up device, the operability was poor because it had to be carried through the cradle or take-out device for the take-up product. Furthermore, the lifting method under the vertical arm condition is inevitably large in size and expensive in equipment cost, and is not good in terms of economy and space. As described above, the conventional armor has various drawbacks, but the take-up arm is formed into an inverted L-shape, a U-shape, a C-shape, etc., and the carry-out device is provided between the take-up arm and the touch roller. We were able to create a permanent automatic batch discharge device.

To summarize again, since there is a tendency for a large-diameter roll to be wound with a large diameter as a slit, the two-point sliding support structure causes bending and causes vibrations. Vibration is prevented by supporting it so that it can move linearly in one direction, and the center of gravity is lowered, and it is supported on the most vibration resistant ground and the weight is also concretely packed to prevent vibration. It is a product that solves all the problems by devising the delivery of rolled products.

At the same time as solving the problem of this vibration, the operability, which is a problem of each conventional technique, is also solved.

The band-shaped sheet has some thickness unevenness, and when it is wound with, for example, thousands of layers, the sheet roll is not a perfect circle.

Although the touch roller has the function of keeping the sheet roll in a perfect circle to some extent if the contact pressure is properly maintained, the rigidity of the supporting arm that supports the core and the separation mechanism that separates the core from the touch roller When the roll is small and the core is easy to change, when the sheet roll begins to lose its true circle shape, the sheet roll vibrates and the contact pressure becomes unstable, making it difficult to keep the true circle shape. .

Therefore, when this is rotated at a high speed, the force received by the sheet roll from the touch roller changes in small steps, and the balance of the rotation of the sheet roll itself becomes poor, causing the sheet roll to vibrate together with the support arm supporting the winding core. The contact pressure of the touch roller also changes in a wave shape, causing the sheet to slip.

As a result of elucidating the cause of such a phenomenon, the inventor of the present invention has focused on one point of Japanese Patent Publication No. Sho 45-20644, which has been the leading role of the conventional belt-shaped sheet winding device in order to prevent the above-mentioned lateral deviation phenomenon. Completely abolish the method of supporting the winding core on the moving support arm.
In the conventional swing-type core support arm that changes the inclination angle as the winding weight increases, all the vibration of the sheet roll that attempts to swing the support arm is added to the drive mechanism for separating the core from the touch roller, and Even if the swing angle changes, the core support at the tip of the support arm changes significantly, and the center of swing does not move. The core support has to be long in order to allow the core to be charged and separated from the touch roller without causing a large difference in the contact pressure direction between the sheet rolls. Since it has a long and flexible structure, the vibration of the sheet roll cannot be prevented. In addition, the force acting on the spacing adjustment table may change in a complicated manner due to changes in the swing angle of the swing-type core support arm, its support position on the spacing adjustment table, and the weight of the sheet roll. Is not preferable from the viewpoint of.

Moreover, even if the pressing direction of the touch roller is constant because the core support is moved away from the touch roller by swinging, the direction of the straight line connecting the centers of the touch roller and the sheet roll changes due to the thickening of the sheet roll. ， Compensation is necessary for precise contact pressure control. Further, since the replacement work of each touch roller inside the core support must be performed through the core support, the replacement work or maintenance of the touch roller is troublesome.

Further, due to the configuration, a new winding preparation work cannot be performed until the sheet roll is moved to another position, and the stop time of the slitter rewinder becomes long.

In this regard, the same can be said for the conventional technique disclosed in Japanese Patent Publication No. 55-293. Japanese Patent Office Sho 55
In the conventional technique disclosed in Japanese Patent Publication No. 293-293, since the contact pressure must be adjusted on the side of the core support that supports a very heavy sheet roll, it is easily affected by the inertia and the like. In addition, since the support arm of the winding core is pivotally supported on the support base, even if the sheet roll is slightly deformed during winding, the support arm swings and the sheet roll easily vibrates.

Furthermore, in another conventional example, which is disclosed in Japanese Patent Publication No. 57-28658, the sheet roll unloading is as follows.
Not considered at all. This winding device is applied to winding a tape or the like having a constant width, and does not have a function of adjusting the distance between the pair of left and right holders that support the winding shaft, so that the strip-shaped sheet dividing width can be reduced. Unlike the slitter rewinder that needs to be changed, it is virtually impossible to apply to the slitter rewinder, and vibration is not considered at the same time.

The outline of the present invention, which is created by solving all of the above problems, is to divide a strip-shaped sheet by a slitter to a winding position on the amount side, wind it to a winding core at each winding position via a touch roller, and wind it. In a sheet split winding device in which the core is separated from the touch roller as the weight increases, a guide mechanism fixed on the base or the ground at right angles to the width direction of the strip-shaped sheet,
Space guides supported by the guide mechanism and capable of moving linearly at right angles to the width direction of the belt-shaped sheet. The distance adjusting bases on both sides of the winding positions are supported by the space adjusting bases and guided, and are movable in the widthwise direction of the belt-shaped sheet. A high-speed sheet split winding, characterized in that a core support having a pair of sheet core support parts for supporting the core projecting inwardly, and a unloading device aligned below the sheet core support part of the core support. Device.

<Operation> The present invention has clarified the lateral shift phenomenon of the belt-shaped sheet due to high-speed winding and suppresses the vibration of the sheet roll during winding, which is the cause, eliminates the conventional support of the core by the swinging arm, and introduces a new anti-rolling mechanism. We have developed a swing core support and movement method.

In addition, we have developed a product that solves all the problems by pursuing the easiness of replacement work of each member according to the improvement of the operability of unloading the sheet roll and the change of the strip-shaped sheet dividing width.

That is, the core support of the present invention does not separate the core from the touch roller by its own swing as in the prior art, but merely restrains and supports the core and integrally supports it on the space adjusting table. It has only been done.

The space adjustment base slides and positions the core support only when the sheet division width changes, but it is integrated with each core support on one side during winding, and as the core becomes thicker, ， Move the guide mechanism little by little.

This space adjustment base is movable in the guide direction of the guide mechanism and is restrained from moving in the other directions to engage with the guide mechanism. , It has a vibration-proof structure that suppresses vibration of the core.

Furthermore, since the core support can slide on the space adjustment table,
The support position of the core support can be easily changed, and the spacing adjustment stand can be moved away from the touch roller at the winding position. In order to replace the touch roller at the winding position, a space for the worker to enter can be created. be able to.

The core support and the space adjustment base are integrated to support the core, and linearly separate the core from the touch roller at right angles in the width direction of the strip-shaped sheet. Since the swinging force acting on the core support is supported by the guide mechanism, the lateral force acting on the core is not increased.

Therefore, the sheet roll has rigidity in the lateral direction, and the weight of the space adjusting table can be increased, so that, for example, when talking about concrete or the like, vibration is unlikely to occur in the sheet roll. Further, when the sheet roll is rolled up, the conveyor is moved from the retracted position to the delivery position below the sheet roll at that position, or almost at the rolled-up position, and the sheet roll is released.
Each core support is retracted to the position where it does not interfere with the movement of the sheet roll in the width direction of the belt-shaped sheet for each interval adjustment base, and the sheet roll is carried out to the machine side by the conveyor. Therefore, as soon as the core support is retracted, the sheet roll can be carried out immediately and the new core can be attached to the core support. Further, when the division specification of the strip-shaped sheet is changed, it is possible to move the core support to a new support position while unloading the sheet roll.

<Embodiment> FIGS. 1 and 2 show an embodiment of the present invention.

FIG. 1 is an elevational explanatory view of a sheet dividing and winding device according to the present invention, and FIG. 2 is an explanatory plan view of the same.

The wide sheet S travels in a sheet traveling path above the winding work space, reaches the grooved roller 1 through the roller group, and is separated into a plurality of lines by the slitter K. Then, the divided sheets are immediately distributed from the grooved roller 1 to the front and rear guide rollers 1a and 1b, and pass through the touch roller 2 in parallel with the touch roller 2 at the same height as the touch roller 2 to form a pair. A sheet roll R is wound around each of the cores C supported by the sheet core support portion at the tip of the core support 10.

The right half of FIG. 1 shows the state where the sheet roll R is wound up, and the left half shows the state where the wound sheet roll R is passed to the carry-out mechanism 24 and the core support 10 is retracted. In the left half of FIG. 1, the state at the start of winding when the core support 10 is moved forward (to the right in the figure) to bring the supported core C into contact with the touch roller 2 is shown by a chain line. During winding, the core C moves from the chain line position at the start of winding shown in the left half of FIG. 1 to the solid line position at the end of winding. As the sheet roll R becomes thicker, the core C gradually separates from the touch roller 2.

Note that FIG. 1 shows a section taken along the line aa in FIG.

A space adjusting table 13 is horizontally provided in the seat width direction along the front and rear winding positions, and the core support 10 is supported on the space adjusting table 13.

In this case, the space adjusting base 13 has a dovetail-shaped protrusion 13a extending in the seat width direction on the upper part thereof, and the core support 10 slidingly engaged with the base of the space adjusting base 13a has a seat width on the space adjusting base. It is guided so that it can move only in the direction. Even if the sheet dividing position by the slitter K is changed, the core support 10 slides on the space adjusting table 13 to move to the winding position corresponding to the new sheet dividing position, and is provided at the base thereof. It can be fixed by the clamp 15. Further, one or both of the pair of core support members is provided with a core drive mechanism (not shown) that drives the core C at its center in order to wind the divided sheets with a required tension. The space adjusting bases 13 are arranged at three positions in the sheet width direction below the front and rear winding positions so that the core C can be separated from the touch roller 2. A guide mechanism 12 such as a rail 12a that extends horizontally at right angles to the seat width direction and is fixed on the base 11 is supported and guided so as to be linearly movable without rattling in other directions. More specifically, a movable movable body (fitting member) that is fitted and guided so as not to cause rattling in the vertical, horizontal, and other directions that cause vibration on the rail 12a of the guide mechanism.
An interval adjustment base 13 is fixed on a foot base 14 fixed on 14a. And, between the base 11 and the space adjusting bases 13, 13,
A drive mechanism (16) is provided for driving the space adjusting bases (13) on both sides in a symmetrical direction all together. In this case, the drive mechanism 16 is arranged in two places on the left and right in parallel to the rail 12a mainly for each one side gap adjusting base, and is fixed to the gap adjusting base 13, so that the drive mechanism 16 is screwed into the screw portion 16b and rotates substantially without backlash. Ball screw shaft 16a with low resistance, servo motor 16c that drives the ball screw shaft 16a at low speed during winding, motor 16d that can rotate the ball screw shaft 16a at high speed in both forward and reverse directions, and the rotation of these motors 16c, 16d is performed by the ball screw. It is composed of an operating gear mechanism 16e for transmitting to the shaft 16a, a transmission shaft 16f, and a heavy gear mechanism 16g. Then, the left and right ball screw shafts 16a are driven, and the space adjusting base 13 and the winding core C can approach and separate in parallel with the touch roller 2. Further, since the ball screw shaft 16a tries to restrain the displacement other than the displacement of the gap adjusting base 13 due to its rotation, even if a large force acts on the gap adjusting base 13 from the outside, the gap adjusting base 13 can be easily moved. Will not be displaced.

A motor driven rack, a pinio mechanism, a fluid pressure cylinder, or the like may be used as a drive mechanism for moving the core C away from the touch roller. In addition, the ball screw shaft 16
The arrangement of a is not limited to two, and the motor 1
One motor may be used for both 6c and 16d. It is also possible to use another screw shaft instead of the ball screw shaft.

Further, if it is necessary to further mechanically ensure the parallel movement of the distance adjusting table, not only the accuracy of the guide mechanism may be increased but also a known parallel movement mechanism may be supplementarily adopted.

These configurations must firmly support the core C and do not cause vibration to the extent that the sheet is laterally displaced even if the sheet roll R eccentrically grows and rotates at high speed. Therefore, the guide mechanism 12 on the floor or the base is fixed, and the rail is restrained from moving vertically and horizontally.
A movable base 14a (see FIG. 3) movably engaged with the base 12a, a leg base 14 fixed on the movable base 14a, a space adjustment base 13 of a support fixed on the base 14, slidingly engaged with the base 14a during winding. Each core support 10 fixed by tightening the clamps 15 has a rotating part or a sliding part in the front-back direction between the tip part of the core support itself and the engaging part of the interval adjusting base 13. It is an integrated structure that does not include,
Anti-vibration structure that does not accept vibration, that is, sufficient weight (such as reinforcing bar to bury cement) and rigidity to prevent it from synchronizing even if a force that causes vibration to the core acts. In addition, they are connected to each other without any looseness so that they are directly connected to the floor surface or the base and have a short height.

In addition, the leg bases 14 on both sides on which the space adjusting base 13 is mounted are extended at a right angle in the width direction of the belt-like sheet, and the engagement area with the guide mechanism 12 is increased, whereby the stability of the space adjusting base 13 is improved. Is increasing. A work floor plate 17 is placed on the upper surface between the legs 14 and 14 to facilitate work on both outsides of the winding position. In the embodiment, the footrest 14 is provided at a total of three places at both ends and in the middle to enhance the vibration damping function. Furthermore, by providing the leg base 14 and the guide mechanism at a large number of places in the middle, and by making these a large number of infinite places, an integrated structure of full support is provided, so that the deflection of the gap adjusting table is further suppressed, and a further anti-vibration function is exerted. be able to.

In addition, in the central part of the dovetail-shaped protrusion 13a on the upper surface of the space adjustment table,
A groove 13b is provided over the entire length of the space adjusting base, and a screw shaft 19 that can be rotated in the normal direction and the reverse direction by driving the rotation drive mechanism 18 is provided in the groove 13b.

On the other hand, each core support 10 slidably engaged on the space adjustment base is
An engaging portion 10a, which holds an engagement / disengagement mechanism capable of engaging / disengaging the screw shaft 19 at appropriate times, is provided in the groove 13b, and the engagement / disengagement mechanism is operated during forward or reverse rotation of the screw shaft. By engaging and disengaging with, it is possible to move to a predetermined position on the interval adjusting table in a short time.

On the other hand, in the center of this device, each core C at the winding position on both sides is
There is a support arm 21 of each touch roller 2 corresponding to the above, an adjustment table 22 protruding to the right or left, and a touch roller guide table 20 on which the adjustment table 22 extends and extends in the sheet width direction.

The support arm 21 is supported by an adjusting table 22 so as to be swingable about one end, and a touch roller 2 supported on the other end of the support arm 21 by a touch roller pressing mechanism (in this case, a fluid pressure cylinder) 23 is seated. The roll R can be pressed with a required pressing force. In addition, each adjusting table 22 includes the core support
Similar to 10, the position can be changed in the sheet width direction with respect to the sheet dividing position. In addition to the touch roller pressing mechanism 23, a touch roller displacement detection device (not shown) for detecting the displacement of the touch roller is attached to each adjustment table 22.

To control the separation and drive of the winding core C during winding, detection signals are input from a touch roller displacement detection device and a winding amount detection device (not shown), and the touch roller pressing mechanism 23 causes the touch roller 2 to make a desired contact. The servo motor of the drive mechanism 16 is arranged so that the core C separates from the touch roller 2 while pressing the sheet roller R with pressure while keeping the touch roller 2 at a substantially constant position.
It is performed by the control device that commands 16c to rotate. The control device is not limited to this, and a known device may be used according to the type of the drive mechanism 16 and the like.

It is also possible to slidably engage the touch roller support arm with the adjusting table so that the touch roller can be linearly displaced.

Furthermore, a mechanism for movably supporting the core C such as the core support pair 10, the space adjustment base 13, and the guide mechanism 12, and a mechanism for supporting the touch roller such as the adjustment base 22 and the touch roller guide base 20. In the space below the sheet roll R between
A carry-out mechanism 24 is provided for carrying the sheet in the sheet width direction.

In this embodiment, the carry-out mechanism 24 is mainly composed of a conveyer (belt conveyor) 24a provided in the space below the front and rear winding position in the sheet width direction as a conveyer and driven by a drive mechanism (not shown), and front and rear gap adjusting tables 13, respectively. The left and right sides of the belt-shaped sheet are guided by a guide mechanism on a base 11 extending at right angles to the width direction of the belt, and can be moved laterally in the front-rear direction as indicated by an arrow A to form a pair of left and right conveyors (belt conveyor) 24a. An elevating mechanism (screw jack) 24b that supports up and down, and an elevating drive mechanism 24c, and a pair of left and right elevating mechanisms (screw jacks) 24b that horizontally move in the front-rear direction all at once. Fluid pressure cylinder). When carrying out the rolled-up sheet roll R, a lateral movement drive mechanism and a lifting drive mechanism 24c
The driving of the conveyor 24a allows the conveyor 24a to move in a horizontal posture between the standby position where the winding work is not hindered and the receiving position directly below the sheet roll R. Therefore, the left and right lifting mechanisms 24b are mechanically or electrically driven in synchronization. In order to move the left and right lifting mechanisms 24b by the same amount at the same time, for example, a beam is provided in the middle between the two to form an integrated structure, or a shaft common to the left and right is rotated in the seat width direction at the base of the left and right lifting mechanisms 24b. Supportingly possible, fixing the pinion to this shaft, and auxiliaryly adopting a parallel movement mechanism of a type that meshes with a rack fixed on the base 11 near the guide mechanism of the traveling mechanism 24b or other known type Is desirable.

In this case, since both ends of the beam-shaped conveyor 24a are supported by the elevating mechanism provided on the left and right outside of the winding area, the space of the winding area can be effectively used. However, the number and arrangement of the elevating mechanisms 24b that support the conveyor 24a may be appropriately selected as necessary, and as long as it has a function of guiding the conveyor 24a by sliding or swinging,
A well-known lifting device such as a jack jack or a hydraulic lifter may be used.

Alternatively, the elevating mechanism may be fixed on the base, and a lateral guide mechanism may be provided between the conveyor and the elevating mechanism to allow the conveyor to move laterally. Receipt of the sheet roll onto the conveyor is not done directly on the top of the conveyor,
It may also be done indirectly via a common or individual pallet. In that case, in order to prepare the pallet at the sheet roll receiving position on the conveyor, it is preferable to provide the conveyor with a function of conveying in both the left and right directions.

In addition, when receiving the sheet roll, an elastic material may be attached to the receiving surface or a buffer mechanism may be interposed in the elevating mechanism so as not to damage the sheet roll. As the lateral movement driving mechanism, a known driving mechanism having a function of laterally moving the conveyor to a predetermined position may be used. Further, it may be provided for each elevating mechanism, or a plurality of elevating mechanisms connected by beams or the like may be laterally moved by one driving mechanism.

On the other hand, the core support 10 is U-shaped and has a space for receiving the conveyor 24a at the sheet roll receiving position below the sheet roll.

The shape of the core support is not limited to the U-shape, but may be an inverted L-shape, a C-shape, a single character extending diagonally or laterally from the space adjusting base in the direction of the touch roller, or a space for receiving the carry-out device. It can vary in consideration.

Briefly explaining the operating procedure of this device, as shown in the left side of FIG. 1, with respect to each pair of core support members 10 and 10 that has rolled up the rolled sheet roll R onto the conveyor 24a and retracted to the solid line position,
First, a new core C is supported, and when the sheet roll R is unloaded and the conveyor 24a returns to the standby position, the motor 16c of the drive mechanism is rotated at a high speed to rotate the core support 1
0, 10 are all advanced toward the touch roller 2, and the core is brought into contact with the touch roller 2 as shown by the chain line in the left half of FIG. The rail 12a of the guide mechanism is fixed on a movable movable body (fitting member) 14a which is fitted and guided so as to prevent it from rattling up and down, left and right, and other directions that cause vibration. An interval adjustment base 13 is fixed on the foot base 14.

When the cut ends of the divided sheets are bonded to the new cores C and the operation of the core drive mechanism (not shown) is started, the sheet roll R on the outer periphery of the core C gradually thickens, and the touch roller pressing mechanism 23
Thus, while the required contact pressure is applied between the sheet roll R and the touch roller 2 according to the driving force, the command of the above-mentioned control device is given to the servo motor 16c and the drive mechanism 16 adjusts the core support 10 and the gap. The base 13 and the winding core C are continuously retracted. The winding core C may be intermittently retracted according to the displacement of the touch roller 2.

In some cases, an oil damper or the like may be provided on the touch roller side to prevent displacement of the touch roller due to a sudden change in the force received from the sheet roll R, or to prevent deformation or eccentricity of the sheet roll. Following this, the touch roller may be allowed to move lightly while maintaining contact with the surface of the sheet roll.

According to the present invention, as a vibration-proof structure, both ends of the core C are firmly restrained and supported by the core support mechanism having sufficient weight and rigidity.
Each core support 10 has a bottom surface, and a space adjusting base having a vibration-proof structure.
It is firmly fixed to the dovetail-shaped ridges 13a on the upper surface of 13 by the clamps 15, and the distance adjustment base 13 is stopped by the screw shaft 16a and the female screw 16b of each drive unit 16 via the long leg base 14. , Core support 10, interval adjustment stand 13, its foot stand 14,
Since the guide mechanism 12 has an integrated anti-vibration structure to suppress the vibration of the winding core C, the sheet roll R cannot generate the vibration that causes the lateral displacement of the sheet.

In this way, when the sheet roll R is wound up, the conveyor 24 is moved to a position right below the central portion which changes depending on the size of the sheet roll R
Move a aside and attach it to the receiving position. Stop the operation and raise the conveyor 24a to move the lower surface of the sheet roll R to the conveyor 24a.
After the core end clamp of the core support 10 is removed and the motor 16c is reversely rotated at a high speed to retract the core support 10, the sheet roll R is placed on the conveyor 24a and carried out. It

Further, in order to change the sheet division width, when the position of the slitter K is changed, the clamps 15 of the respective core support members 10 are loosened and slid on the space adjusting table 13 to be placed at corresponding positions. Although the position of each touch roller 2 which is not included in this is also changed, the touch rollers 2 on both sides can be positioned at the same time by sliding on the guide table 20 for both left and right. In addition, in order to move each core support to a required position, a well-known positioning drive mechanism may be used instead of manpower.

Although one embodiment has been described above, the present invention can be variously changed and applied by a well-known technique of the designer depending on the implementation condition.

For example, the fitting member 14a in the above-described embodiment is fixed on the floor or the base, and the rail fixed to the space adjusting table is guided by the fitting member, or the rail that is floated from the floor or the base and firmly supported. Guide slidably through the mating member, directly guide the gap adjusting base with a rail without using a foot stand, use a commercially available linear motion bearing (commonly called linear way), Alternatively, by guiding through rolling elements such as wheels between the guide surface of the rail and the fitting member, or by making the upper surface of the base plate a sliding surface and directly slidingly engaging the lower surface of the space adjustment base to guide it. , A guide mechanism may be used to support and guide the space adjustment table.

Further, the method of attaching the winding support to the space adjusting base is not limited to the above-described embodiment, such as the use of a commercially available linear motion bearing and sliding engagement, and the fixing of the core support is performed by bolts or the like. A clamp mechanism may be used, and the core support is not limited to being engaged with the upper side of the space adjusting table.

In addition, in the embodiment, the gap adjusting base is supported by the set of three rails provided at both ends and the central portion of the gap adjusting base, but the guide mechanism adjusts the gap such as the number and position of the rails. The position to support the base and the sheet dividing and winding device were rotatably supported in a form in which the core is driven centrally, a form in which center drive and surface drive by a touch roller are used in combination, a surface drive type, and a fixed position. One or two common touch rollers are wound while each sheet roll is in contact, and the touch roller is not in contact with the sheet roll,
Depending on the conditions, it is possible to adopt a type in which the touch roller and the sheet roll are wound while maintaining a predetermined gap, or a type in which the traveling path of the belt-shaped sheet is provided in the floor below the winding position.

The carry-out device is not limited to the conveyor, and if it has a function of supporting the sheet roll and carrying it out in the sheet width direction, it is provided for each sheet roll and receives the sheet roll independently and conveys the sheet roll independently. A conveyance device capable of performing sheet winding, a carriage provided on the side of the sheet division winding device in the widthwise direction of the strip-shaped sheet winding device, moved from the standby position when the sheet roll is unloaded, and provided on the touch roller side of the gap adjusting table. , Other transport devices can be used. Furthermore, the unloading device can only be moved up and down, and in some cases it may not require lateral movement.

The delivery of the sheet roll from the core support to the unloading device is performed by moving the unloading device to the sheet roll receiving position and supporting the sheet roll, and then releasing the sheet roll by the core support. Alternatively, the sheet roll is temporarily supported on the core support or another location, and after the sheet roll is released, the temporary roll mount and the temporary roll mount on which the sheet roll is placed on the discharge roll-out device are carried out from the sheet roll temporary roll mount position. Alternatively, a sheet roll delivery device having a mechanism for moving upward may be provided. In this case, it is possible to eliminate the need to move the conveyor device to the receiving position. Further, the position at which the unloading device receives the sheet roll is set to a position where the sheet roll is wound up or a position where it is slightly retracted from that position, or the unloading device receives the sheet roll at the retracted end of the core support. It is also possible to start the conveyance to the machine side after the lateral movement to the touch roller side. Further, the movement of the carry-out device to the sheet roll receiving position is not limited to the above-mentioned embodiment, and the carry-out device is moved in the lateral direction by interlocking with the space adjusting base by placing it on the space adjusting base or via a coupling mechanism such as a coil spring. After that, it moves up, moves diagonally, tilts the seat roll receiving surface vertically and waits, then swivels to the horizontal position to reach the receiving position. There are various possibilities, such as getting stuck.

In the above-mentioned embodiment, the core is designed to be separated from the touch roller in the horizontal direction, but it may be separated in the direction close to the horizontal direction. Further, the core support may be movably supported by a plurality of gap adjusting bases.

The winding core tube that penetrates through the winding shaft or the winding shaft itself is used as the winding core.
Even if the core support releases the core, the core support should be able to support the lower surfaces of both ends of the core. After releasing the clamps of the core support first, the core support is unwound by the unloading device. It is also possible to slightly lift the sheet roll on the core whose bottom surfaces are supported by the core support and then retract the core support. Alternatively, the core may be projected on the touch roller side of the core support. A space for transporting the sheet roll is provided below the support part so that the core support does not move backward when the sheet roll is carried out.
It is also possible to move the sheet roll received by the carry-out device to an empty space for carrying and then carry it in the width direction of the belt-shaped sheet.

<Advantages of the Invention> The present invention is to study the cause of the end face of a wound sheet roll being uneven when the plastic film whose surface is extremely slippery is disassembled as a target sheet and is wound at high speed in a sheet split winding device, Clarified.

That is, even if the contact pressure between the touch roller and the sheet roll is properly adjusted to prevent the sheet roll from being deformed and the end misalignment, if the rigidity of the core support and the entire approaching / separating mechanism is small, the winding belt is wound. Deformation of the sheet roll caused by uneven thickness of the sheet cannot be suppressed only by controlling the contact pressure between the touch roller and the sheet roll, and the sheet roll becomes a vibrating state field due to the rotation of the deformed sheet roll. We have found that it is the cause of the lateral slippage phenomenon on the winding sheet.

As a countermeasure, since it is difficult for the conventional winding arm that swings with the winding weight to suppress the vibration with the conventional winding arm, as a new winding core supporting means, the winding means moves linearly with the winding weight and moves away from the touch roller. We have developed an anti-vibration structure. It integrates all the core supports with the space adjustment base during winding and moves them along the guide mechanism without slack and without lifting as the winding progresses, so that the core has a large mass and rigidity. It moves while controlling the vibration, that is, the vibration of the sheet roll.

In addition, when changing the strip sheet division width and division position, the core support can slide on the space adjustment base to easily change the core support position. Since the core supporting body is supported by the above-mentioned structure, it is not necessary to provide a driving mechanism for moving the core toward and away from the touch roller for each core supporting body.

In order to prevent vibration with the conventional device, there was only a very disadvantageous method even with the principle of "lever", in which the rotation of the base of the take-up arm with the sheet roll as the vibration source at the tip was stopped.

The present invention supports each sheet roll by maintaining a simple core support mechanism without complicating the work of changing the core support position of the core support, which is often necessary in the band-shaped sheet split winding official approval. The entire core support is installed in the large anti-vibration structure on both sides and moves straight without any slack, thus strengthening the groundbreaking vibration-preventing force, preventing the sheet lateral deviation phenomenon due to vibration, and preventing the unevenness of the sheet roll end surface. It was successful, and the cost of the equipment, which was extremely easy to operate and productive, was reduced.
