Description

Detailed Description of the Invention (Industrial Field of Application) This invention has the following advantages: - A web of paper, plastic film, etc. is divided into a plurality of strips by a slitter, and the nine-divided web is passed through a touch roller provided at a fixed position. The present invention relates to a web dividing winding device that winds the web around a core at around one winding position, and is equipped with a mechanism for simultaneously unloading the winding roll.

(Prior Art) As a web dividing winding device of this type, there is a conventional one, for example, a center drive type sheet winding device with a slitter that longitudinally cuts a sheet band into multiple strips and winds them onto multiple cores at the same time. a common receiving roller at a fixed position for winding each longitudinally cut sheet band and distributing it to a plurality of winding cores; and a common receiving roller that supports each of the winding cores at the upper end and rotates while being circumscribed by the common receiving roller. A plurality of pairs of swinging supports whose spacing can be freely adjusted to be wound as sheet rolls by being driven, an actuator attached to each pair of swinging supports and adjusting the external contact pressure between the winding core and the receiving roller, and the swinging supports. A magnetic powder clutch for sheet tension control is inserted and equipped in the transmission mechanism extending from the base to the tip of each pair of dynamic supports, and each winding of each pair of rocking supports detects the tilting angle due to an increase in the roll diameter of the roll. There was one characterized in that it was equipped with a diameter detection means and a respective control device that automatically controlled the transmission torque of the magnetic particle clutch to a value suitable for each sheet roll winding diameter using a signal current from the detection means. . (Refer to Japanese Patent Publication No. 53-33711) Furthermore, a large number of take-up rolls each supported by an independent support arm are brought into pressure contact with a single common contact roller by a contact pressure applying mechanism provided on each support arm, and one roll is produced. The take-up rolls and/or contact rollers are driven such that the slit strip is 1) wound onto each take-up roll via the IJ contact roller, with each support arm relative to said common contact roller; It is pivoted on one common support base so that it can swing back and forth within a small angular range from the vertical support position.

The rocking displacement of each support arm corresponding to the increase in the winding diameter of each take-up roll is detected on a representative or average basis, and based on the detected value, each take-up roll support arm as a whole always maintains a substantially vertical support state. In some cases, the common support base and the common contact roller are actively retracted in the horizontal direction under automatic control so as to maintain the position. (Tokukō 1977-
(Refer to Publication No. 293) The take-up roll completed with these devices can be adjusted by tilting the support arm together with the common support base in the direction opposite to the touch roller, etc.
It was being swiveled onto a receiving stand prepared in a space on the opposite side of the touch roller.

(Problem to be Solved by the Invention) However, among these conventional web dividing winding devices, the former supports a heavy winding roll (sheet roll) at the upper end of a swinging support. It became unstable, and during high-speed operation, the take-up roll danced on the touch roller, causing the support arm to vibrate back and forth.

The contact pressure between the take-up roll and the touch roller tends to fluctuate drastically. In some cases, the take-up roll may be momentarily lifted off the touch roller. By making contact between the take-up roll and the touch roller with the required contact pressure, the amount of air that is drawn in between the web layers of the take-up roll together with the web being taken up during the second winding is adjusted, and the amount of air caught between the web layers of the take-up roll due to uneven web thickness, etc. This occurs due to deformation and a decrease in the coefficient of friction between the web layers of the take-up roll due to the air table effect.

This prevents uneven end surfaces of the take-up roll, but as mentioned above, if the contact pressure between the take-up roll and the touch roller fluctuates drastically, the amount of air caught between the web layers of the take-up roll cannot be properly adjusted, resulting in 9 rolls. This causes problems such as deformation of the take-up roll and unevenness of the end face of one take-up roll, resulting in a significant deterioration in the quality of the take-up roll and furthermore, a loss of product value of the take-up roll.

Furthermore, the latter of the above-mentioned conventional web dividing winding devices has a support arm pivoted on a common support base, the support arm being maintained in a substantially vertical position, and the common support base being horizontally moved from a common contact roller. The difference from the former is that the core on the support arm is separated from the touch roller in response to the growth of the single take-up roll by actively retracting it, but similarly to the former, the core is supported at the upper end of the pivoted support arm. Therefore, the same problem as the former occurs.

In addition, a swing support body (support arm) to support the 9-volume core
It has been known for a long time to use an oil damper to suppress the vibrations of In addition to vibrations of the swinging support (support arm), which can sufficiently suppress vibrations of the winding arm), vibrations of the entire winding device are also added, making it impossible to form a high-quality winding roll.

Furthermore, when the take-up roll is completed, the take-up roll is rotated and carried out to the receiving stand ``2'' prepared in the space on the opposite side of the swinging support arm (support arm) from the touch roller.
Since it is installed at the work place of the workers, the winding roll is carried out to the work spaces of nine workers. If there is a take-up roll in the work space, it will get in the way of the winding preparation work such as attaching the winding core to the winding device for the first new winding. Since it is necessary to perform winding preparation work after moving to the location, it becomes difficult to perform one winding preparation work in a short time. In addition, it is not preferable for the arm supporting the take-up roll to fall into the work space 9 from the viewpoint of ensuring the safety of the workers.

Recently, there have been many webs that are difficult to wind because they have slippery surfaces, such as the polyester film that is the base of video tapes, and the edges of the winding roll tend to be uneven when winding. In order to increase the force, there has been a demand for a web dividing winding device that can increase the single winding speed, has a high operating rate, and can produce high-quality winding rolls with high productivity. However, conventional web dividing and winding devices have not been able to fully meet these user demands.

(Means for Solving the Problem) Therefore, the present invention divides the web into a plurality of strips using a slitter, passes the nine-divided web through a touch roller provided at a fixed position, and separates each strip at two or more winding positions. In a web dividing winding device for winding one winding roll around a winding core, each of the above-mentioned front and back winding positions is provided so as to be movable linearly in the longitudinal direction of the web.

a spacing adjustment table having a guide surface extending parallel to the width direction of the web; and a protrusion that is slidably engaged with the guide surface, is attached to the spacing adjustment table, extends upward, and protrudes toward the touch roller. A support body having an arm portion and positioned near the end of the winding core, and a support body that is pivotably supported by the protruding arm portion of the support body, and the winding body is mounted below the pivot point and at the height of the touch roller. A hanging arm that removably supports the core, and a contact pressure applying device 114 that is provided on the support and presses the hanging arm toward the touch roller.

a drive mechanism that moves the interval adjustment table in the longitudinal direction of the web;

During winding, the drive unit ↑j4 is commanded to take up the divided web twice on the two cores so as to keep the swing angle of the hanging arm within a predetermined small range. A control device is provided on the touch roller side of the support body to control the amount of retreat of the nine-spacing adjustment table according to the growth of the support body.

and arranged in a space below the core support point by the hanging arm.

and a carry-out mechanism for carrying out the completed winding roll on the winding core supported by the hanging arm from that position to the side of the web dividing winding device when viewed in the longitudinal direction of the web. Features.

In addition, while the web is divided into multiple strips by a slitter, the two-split web is distributed to the front and rear winding positions via a touch roller, and the web splitting and winding device winds the web around each core. an interval adjustment table provided at each winding position so as to be movable linearly in the longitudinal direction of the web and having a guide surface extending parallel to the width direction of the web; A core support device is attached to the core supporting device, extends downward, is positioned near the end of the core, and supports the core at the same height as the touch roller at its lower end; The winding roll may be provided with an unloading mechanism that receives the lifted winding roll in a space below the winding roll and transports it from the winding position.

(Function) Since the winding core support point is below the pivot point of the hanging arm, the hanging arm supports the winding roll by suspending it from the support body. The gravity acting on the take-up roll by supporting the winding core in this way acts to return the hanging arm to the vertical position even if the hanging arm tilts from the vertical position, so the 9-winding roll is stabilized. becomes easier. If the take-up roll is supported by the upper end of the arm whose lower end is pivotally supported as in the past, if the arm tilts even slightly from the vertical position, the gravity acting on the take-up roll will cause the arm supporting the take-up roll to It is not easy to stabilize the support of the take-up roll because it works to tilt the take-up roll even more. and.

The greater the weight of the take-up roll, the more difficult it becomes to stabilize the take-up roll. However, when two take-up rolls are suspended and supported by hanging arms, the greater the weight of the first take-up roll, the more stable the take-up roll becomes.

The spacing adjustment table slides the support and positions it at a position suitable for changing the web dividing position. Furthermore, by moving in a linear motion, the 1-interval adjustment table stably supports the support body, suppresses vibrations at the pivot point of the hanging arm, and retreats from the touch roller. Furthermore, by receding the core supported at the same height as the touch roller from the touch roller by horizontal linear movement, the winding tension of the divided web at the point of contact between the touch roller and the take-up roll and the per-roll The gravity of the take-up roll acts vertically and does not affect the contact pressure between the touch roller and take-up roller, and the direction of the contact pressure between the touch roller and take-up roll is always constant, so two take-up rolls To eliminate the need for correction of pressing force by a contact pressure applying mechanism even when growth occurs. The conventional arm for supporting the winding core is pivoted on a support stand provided on the lower side, so compared to the distance between the pivot point and the winding core support point, the distance between that pivot point and the contact pressure applying mechanism and the oil The distance between the engagement point with the damper is extremely small, and the fluctuating force acting on the core support point due to slight deformation or eccentric rotation of the 9-winding roll is absorbed by the contact pressure applying mechanism of the arm and the engagement point with the oil damper. Then, the effect will be magnified several times.

The contact pressure applying mechanism and the oil damper were unable to stably maintain the posture of the arm for supporting the first core. However, in the groove construction in which a support body is provided along the hanging arm that supports the winding core of the present invention, the distance between the pivot point of the hanging arm and the engagement point of the contact pressure applying mechanism, etc. is adjusted as necessary. The size is close to the distance between the pivot point and the core support point.

Or, by selecting a larger size, it becomes easier to provide a contact pressure applying mechanism, etc. Providing the support body so as to protrude above the height of the support point of the winding core from the interval adjustment table increases the height of the mechanism for supporting the 9-winding core, which in turn makes it difficult to support the winding roll. Although it may seem unstable, the support of the take-up roll becomes stable as described above, and the control of the contact pressure between the first take-up roll and the touch roller becomes simple. And it stably supports the two take-up rolls.

When the contact pressure between the take-up roll and the touch roller is properly controlled, the touch roller works to correct the deformation and eccentricity of the take-up roll, and the take-up roll whose deformation and eccentricity have been corrected becomes more stable. and rotate.

The unloader groove supports the take-up roll released from the hanging arm.

It is sent out to the side of the device through the space on the touch roller side of the support.

Further, the winding roll is similarly stabilized when the winding core is supported at the lower end of the winding core support device extending downward from the nine-interval adjustment table. Then, the unloading mechanism receives the take-up roll in the empty space below the core support device.

It moves from that position to the take-up roll unloading position outside the take-up device. Since the carry-out mechanism can move to the empty space below the core support device and stand by even during winding, preparations for the next winding can be made as soon as the carry-out mechanism moves from the empty space below the core support device.

(Embodiment) FIGS. 1 and 2 show a first embodiment of the present invention. 1st
The figure is an elevational view schematically showing a web dividing and winding device according to the present invention, and FIG. 2 is a plan view as well.

The web W fed out from a raw roll (not shown) or the like is guided to the slitter 2 via a group of guide rollers.
It is divided into multiple articles. Near the slitter 2 is a web W in the longitudinal direction.

That is, according to FIG. 1, there are winding positions that move back and forth in the left and right direction, and between these winding positions there is a fixed position at a certain height.

According to this embodiment, two touch rollers 3.3 are provided in parallel and at the same height. Each of the touch rollers 3.3 has a length slightly larger than the width of the web W, and both ends thereof are supported by a frame 4.4 so as to be able to rotate twice in parallel to the width direction of the web W.

Each of the divided webs CW passes through one of the front and rear touch rollers 3, and is alternately wound around the winding core C at around 9 winding positions to form one winding roll R. And 2
The take-up roll R grows while contacting the touch roller 3.

At the front and rear winding positions, winding devices for winding the nine-divided web CW onto the winding core C are provided so as to face each other, and each has a similar configuration and function. Therefore, detailed explanation will be given regarding one winding device. The winding device includes an interval adjustment table 5 that can move linearly in the longitudinal direction of the web W so as to correspond to the web W. The interval adjustment table 5 needs to move smoothly and stably in a straight line to avoid vibration. Therefore, according to this embodiment, the nine-spacing adjustment table 5 is fixed on bases 6 arranged at three locations in the width direction of the web W as shown in FIG. The sliding bodies 8 were each fixed on the slide bodies 8 of a linear motion bearing (commonly known as a linear way) consisting of a body 8. The slide bodies 8 were fixed on a base plate 9. It is slidably engaged with a rail 7 extending horizontally in the direction of the operator's hand of the web W, and is engaged so as not to move substantially in directions other than the sliding direction. Further, the two-spacing adjustment table 5 has a guide surface 5a on its upper part, which has a dovetail cross section and extends parallel to the width direction of the web W, as shown in FIG.

Supports 10 are mounted on the interval adjustment table 5 and are positioned near both ends of each winding core C placed at a winding position to wind up the divided web CW. The support body 10 extends upward from the two-distance adjustment table 5, and has a protruding arm portion 10a that protrudes toward the touch roller 3 at its upper portion. The base portion 10b of the support body engages with the guide surface of the spacing adjustment table 5 so as to be slidable. The support body 10 can slide and move parallel to the width direction of the web W on the interval adjustment table 5, and can be fixed to the interval adjustment table 5 by the clamp device 11 at a desired position.

Moreover, the support body 10 is.

A hanging arm 12 is pivotally supported on the protruding arm portion 10a. The hanging arm 12 passes through the pivot point 02. It can swing around an axis parallel to the touch roller. The pivot point 02 of the hanging arm 12 by the support 10G is located at a higher position than the height of the touch roller 3, and pivots the protruding arms 10a, 10a of the pair of supports disposed on both sides of the first winding core C. The hanging arms 12° 12 formed as a pair are parallel to the touch roller 3,
Moreover, the winding core C can be rotatably supported at the same height as the touch roller 3. In addition, in order not to impair the posture of the winding core C parallel to the touch roller 3, each of the pair of hanging arms 12, 12 has a common rod 13 at its upper end, and both ends thereof can be removed. Both of the pair of depending arms 12.12 can be moved. A contact pressure applying mechanism 14 is provided on the support body 10 in order to press and bias the 9-winding core C against the touch roller 3 and adjust the contact pressure between the take-up roll R and the touch roller 3 to a desired level. ing.

The contact pressure applying mechanism 14 can then engage the depending arm 12 and push the depending arm 12 in the direction of the touch roller 3 .

The contact pressure applying mechanism 14 is.

According to this embodiment, the air-hydro tank (not shown) provided on the support 12 and the support 1 are placed at the height of the second core support point 01.
0 and a hydraulic cylinder 14a that engages with the hanging arm 12, and the air-hydro tank converts compressed air pressure into hydraulic pressure to operate the hydraulic cylinder. When such a contact pressure applying mechanism is used, the hydraulic cylinder 14a can obtain the effect of suppressing the vibration of the hanging arm and the effect of adjusting the contact pressure, similar to an oil damper, thereby eliminating the need for an oil damper. be able to.

When the number of divisions of the web W by the slitter 2 and the division width are changed, the winding device uses a support 10 to support the winding core C of a length suitable for the divided web CW at the corresponding position.
By attaching the webs CW to appropriate positions on the interval adjusting table 5, it becomes possible to wind up divided webs CW of various widths.

The winding core C supported between a pair of hanging arms 12.12 is driven by a rotary drive device (not shown) attached to one or both of the pair of supports 12. The touch roller 3 is rotationally driven in combination with surface drive by bringing the take-up roll R into contact with the roller 3.The touch roller 3 is rotated by the motor of the guide roller 1 (not shown) via a continuously variable transmission groove (not shown). The speed can be slightly varied with respect to the circumferential speed of the guide roller 1. However, if necessary, a method may be adopted in which the winding core C is driven by either center driving or surface driving.

When the winding row/L/R around the winding core C grows, the winding core C
If we assume that the 9-interval adjustment table 5 is fixed, only the hanging arm 12 will tilt in the direction of moving the winding core C away from the touch roller 3, and the tilting range of the hanging arm 12 will be Since it is limited to a small size, it is not possible to obtain a winding roll with a large outer diameter.

Therefore, as the take-up roll R grows, it becomes necessary to move the 1-interval adjustment table 5 back from the touch roller 3. Therefore, according to this embodiment, the two threaded rods 16 screwed into the screw receiving member 15 of the nine-spacing adjustment table 5 and the threaded rod 16 are rotationally driven. A drive mechanism 19 is provided on the base 9 and includes a motor 17 capable of forward and reverse rotation, and a rotation transmission mechanism 18 that transmits the rotation of the motor 17 to both threaded rods 16 so that they can rotate synchronously.

By driving this drive mechanism 19, the distance adjustment table 5 is moved to the web W.
can be moved back and forth in the longitudinal direction along the rail 7. Also.

To suppress the tilting angle of the hanging arm 12 within a predetermined minute range during winding.

A control device (not shown) is provided which instructs the drive mechanism 19 to control the amount of retraction of the interval adjustment table 5. The control device receives a signal of the take-up roll R diameter from the take-up roll diameter detection device,
The amount of retraction is commanded in accordance with the signal of the diameter of the take-up roll R, and the tilting angle of the hanging arm 12 is detected, and in response to the detection signal, a command is given for slight correction of the amount of retraction, and the hanging arm 12 is
The nine-spacing adjustment table 5 can be smoothly retreated so as to keep the swing angle within a predetermined small range and keep the hanging arm 12 substantially vertical.

Located on the touch roller 3 side of the support 10 and hanging arm 12
The winding roll R, which is completed by winding the divided web CW of a predetermined length around the winding core C, is placed in the empty space below the winding core support point O1 of A take-out mechanism 20 is provided to take out the web W to the side when viewed in the longitudinal direction of the take-up device. According to this embodiment, the unloading mechanism 20 includes a conveyor device 21 for moving nine take-up rolls R in the longitudinal axis direction thereof, and a conveyor device 21 for moving the nine take-up rolls R in the longitudinal axis direction thereof.
1 and a lifting device 22 that moves the robot up and down. The elevating device 22 is guided by rails 23 provided on the base 19 and supported so as to be movable in the longitudinal direction of the web W. 1. The elevating device 22 is supported movably in the longitudinal direction of the web W by means of a drive means (not shown) or an extendable connecting means such as a coil spring with a spacing adjustment table. Due to the action, the conveyor device 21
can be moved in the longitudinal direction of the web W.

Since it is supported by the hanging arm 12 of the completed take-up roll R, the first take-up roll R can be moved by simply positioning the conveyor device 21 below the second take-up roll R and releasing the take-up roll R from the hanging arm 12. It can be easily transferred onto the conveyor device 21.

Next, the operation of this web dividing and winding device will be explained.

The winding cores C are supported by the hanging arms 12 of the front and rear winding devices so as to be suitable for the dividing position of the web W by the slitter 2, and the interval adjustment table 5 is advanced by the driver tIIt19 to move each winding core C onto the touch roller 3. After the web CW is placed at the contacting winding start position and the leading end of the divided web CW is stopped on each winding core C, winding is started. At this time, the conveyor device 21 is evacuated from the support body 121 interval adjustment table 5 etc. by the elevating device 22 of the carry-out mechanism 20. When winding is started, the web W is unwound and the winding core C is driven to rotate, and the web W is divided by the slitter 2 and wound by one or more winding devices. During winding.

Each winding roll R is pressed against the touch roller 3 with a desired pressing force by the contact pressure applying mechanism 14, and the contact pressure between each winding roll R and the touch roller 3 is individually controlled.

As the winding roll R grows, the interval adjustment tables 5 of the winding devices 1 and 1 move in opposite directions.

The respective winding cores C, which are moved back and placed at the second winding position by the action of each drive mechanism 19 and the control device, are separated from the touch roller 3 in batches for each winding position on one side. Further, the winding tension of each divided web CW is also individually controlled via the winding core C driving means. When the take-up roll R is completed, the 1-interval adjustment table stops retracting at a predetermined position.

The lifting device 22 moves, and the conveyor device 21 is attached directly below the take-up roll, and is raised by the action of the lifting device 22 to support the lower surface of the take-up roll R. After the hanging arm 12 releases the take-up roll R, the 2-distance adjustment table 5 is moved backward, the support 10 and the hanging arm 12 are evacuated from the take-up roll R on the conveyor device 21, and the take-up roll R is moved back. Create space for movement in the longitudinal axis direction. Next, the conveyor device 21

Immediately after the hanging arm 12 is retracted from the winding roll R, the operator picks up the winding core C for the second winding from the hanging arm from above the work floor 24 provided on the opposite side of the support 10 from the touch roller. The conveyor device 21 can be attached to the
This can be done while transporting the take-up roll R. Further, by using the conveyor device 21, the floor area required for carrying out the nine winding rolls R on the side of the web dividing winding device can be reduced.

FIG. 3 shows a second embodiment of the present invention. FIG. 3 is a schematic elevation view with one winding device of the web dividing winding device omitted. In this embodiment, the contact pressure applying mechanism 14 includes an air cylinder 14c.

The oil damper 25 is engaged with the lower end of the hanging arm 12 extending further downward from the winding core support point 01, and the touch roller 3 is one touch roller common to the winding roll R at the front and rear winding positions. This is different from the previous embodiment in that only one of the following embodiments is provided.

FIG. 4 shows a third embodiment of the present invention. FIG. 4 is a schematic elevational view with one winding device of the web dividing winding device omitted. In this embodiment, the support 10 gradually curves and projects onto the upper protruding arm 10a', and its base 10b and the interval adjustment table 5 are moved from just below the hanging arm to the opposite side of the touch roller 3. The unloading mechanism 20 can move parallel to the longitudinal axis direction of the second take-up roll R, and during the first take-up, the unloading mechanism 20 can be moved parallel to the longitudinal axis of the web W of the web dividing take-up device. A movable stand 26 that moves from the standby position to the lower blade of the take-up roll R, which is waiting at a standby position on the side and is supported by the hanging arm 12 when carrying out one take-up roll, is attached to the movable stand 26.

This embodiment differs from the first embodiment mainly in that the L/R is carried out.

According to this embodiment, it is not necessary to increase the moving distance of the one-interval adjustment table 5, and the operation of the drive mechanism 19 is also simplified.

Furthermore, if the unloading mechanism 20 is moved to the standby position, the vacant space can be used, making maintenance and inspection easier.

FIG. 5 shows a fourth embodiment of the present invention. In this embodiment, the web is wound with relatively little thickness unevenness, and the first winding roll R is also hardly deformed. Therefore, the hanging arms 12 that support the winding core C as a pair are designed to be able to swing independently. Therefore, unlike the previous embodiment, a common rod is not fixed to the pair of hanging arms 12. Then, the contact pressure between the two-winding roll R and the touch roller 3 is precisely adjusted to a desired level by a contact pressure applying mechanism 14 such as a velopram cylinder or a low-friction cylinder that is supplied with air at the adjusted pressure. .

In the embodiments described so far, the spacing adjustment unit is supported on the rail on the base, and the hanging arm is pivoted at the tip of the support extending upward on the spacing adjustment table, and the hanging arm is pivoted below the pivot point. The winding core is supported in a suspended state via hanging arms. Next, a web dividing winding device will be described which supports the winding core in a suspended state in the same way, but has a structure slightly different from that of the previous embodiments.

This web dividing and winding device divides the web into multiple strips with a slitter, distributes the divided web to the front and back winding positions via a touch roller, and winds it around each core. , is almost the same as the embodiments described so far. In this device, winding preparation work 1
It is desirable to select the height of the support point of the winding core at a height that is convenient for carrying out the winding roll. This device is provided with beam-shaped interval adjustment tables above the winding cores at the front and rear winding positions. This distance adjustment table has a guide surface extending parallel to the width direction of the web, and is provided to allow linear movement (i+J) horizontally in the longitudinal direction of the web. For example, in order to install the interval adjustment table in this way, 4.

A machine frame is arranged on both sides of the interval adjustment table in the width direction of the web, and rails similar to those in the previous embodiment are attached to this machine frame,
You can fix both ends of the spacing adjustment table to the slide body that engages with this rail and support both ends, or you can install a gate-shaped machine frame of the required height that straddles the web, and use the center beam of this machine frame. A plurality of rails are attached to the lower surface at predetermined intervals in the width direction of the web, and a spacing adjustment table is fixed to a slide body that engages with the rails to support the web at three or more locations.

Any appropriate means may be used as necessary. For this interval adjustment table.

At least in accordance with the number of winding cores at the winding position, pairs of core support devices are attached to the guide surface in slidable engagement and extend downwardly. And each core support device.

It is positioned near the end of the core at the winding position, and the core can be supported at the lower end at the same height as the touch roller.

The winding core support device includes a support body that is fixed to the interval adjustment table during nine windings as in the above-mentioned embodiment, and a hanging arm that supports the first winding core so that it can be moved slightly with respect to the support body. Alternatively, the structure may be such that it is integrated with a first interval adjustment table that supports the winding core so that it does not move relative to the interval adjustment table during the second winding. In the case of a structure in which the winding core support device is integrated with the interval adjustment table 1. In order to individually adjust the contact pressure between the touch roller and the take-up roll, an individual touch roller is provided for each winding core.

A contact pressure applying mechanism is provided on the supporting means side of the touch roller,
It is sufficient if each touch roller can be individually pressed against the take-up roll with a desired pressing force. Each core is supported at an appropriate height by the core support device while suspended from the interval adjustment table, so it is possible to create a space between the take-up roll and the floor. can. The device is equipped with a take-up roll delivery mechanism that can enter this cavity. The unloader groove receives the winding roll wound up by the winding core support device in a space below the winding roll, and can carry it out from the winding position. One embodiment of this unloading mechanism will be described as follows. That is, the unloading mechanism includes a cart for each winding position before and after one. The trolley is provided with a winding roll receiving section having a width that allows the winding rolls wound up at the winding position to be received all at once. Then, the cart moves on the floor in the longitudinal direction of the web so that the take-up roll delivery position outside the take-up device can reach the take-up roll receiving position in the lower space of the core support device, and the winding is completed. Before releasing the rolled take-up roll from the core support device, support the bottom surface of the take-up roll with a take-up roll receiving section provided on the trolley to prevent the fall impact from being applied to the take-up roll when the first take-up roll is released. 1 to do
It is preferable that the truck is provided with a lifting device for lifting and lowering the take-up roll section.

According to the unloading mechanism of this embodiment, a cart is prepared at the take-up roll receiving position during the first winding, and when the second take-up roll is completed and transferred from the core support device to the take-up roll receiving section on the cart. 9
The cart immediately moves to the take-up roll unloading position. As soon as there is no cart at the winding position, the next winding preparation work can be carried out and nine windings can be started. After the take-up roll has been unloaded, the cart is again prepared at the take-up roll receiving position in the empty space below the core support device during winding. Furthermore, the unloading mechanism is as follows.

The present invention is not limited to this embodiment; for example, it may be provided with a conveyor device fW as described in the previous embodiment. When the winding core is supported by each core support device and winding is started, the distance adjustment tables 9 and 9 are driven in directions away from each other by their drive mechanisms to correspond to the increase in the radius of the winding rolls. The web is moved in the longitudinal direction of the web, and the core is separated from the touch roller together with the core support device.

Although this invention has been described above with reference to a small number of embodiments, various modifications may be made thereto without departing from the spirit of the invention. for example.

The number of supports provided in advance on the two-spacing adjustment table may vary depending on the splitting specifications required of the web splitting and winding device.

In addition, the web passes through a running path provided below the winding device.
You may also let it roll out. The direction of linear movement of the spacing adjustment table is not only completely horizontal.

It may be slightly tilted from horizontal as long as there is no problem. Further, the height of the center of the touch roller and the height of the core support point may be approximately equal as long as variations in contact pressure and winding tension can be substantially ignored. Further, the hanging arm is not necessarily provided completely vertically, but may be approximately vertically provided. It is also possible to use a hydraulic servo mechanism or the like as a drive mechanism for the distance adjustment table, or to use a known control device for instructing the operation of this drive mechanism.

Further, the touch roller may be provided individually for each divided web.

The unloader groove may be formed by a transport robot provided for each winding roll, or may be of a type in which one winding roll is dropped by a very small distance and received.

(Effects of the Invention) According to the present invention, vibration of the single winding device is suppressed. Further, adjustment of the contact pressure between the nine-winding roll and the touch roller is simplified. Therefore, the contact pressure between the 9th winding roll and the touch roller during 9th winding is stable and accurate, so the 1st winding speed can be increased without causing defects such as uneven end surfaces of the 3rd winding roll. . Also.

A high quality winding roll can be obtained even when the winding roll becomes extremely heavy due to a long winding length or the like.

Furthermore, the unloading mechanism makes it possible to automate the unloading work of the completed winding roll, and also allows the preparation work for one winding to be carried out while unloading the winding roll, so there is no need to stop the operation of the web dividing winding device. It can save time. Therefore, the productivity of the web dividing and winding device is significantly improved. Further, safety can be improved in the work of carrying out the 9-winding roll and the work of winding up the semi-'A'a'a.
