Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention divides a web of paper, plastic film, or the like into a plurality of lines by a slitter, and allows the divided web to pass through a touch roller provided at a fixed position. The present invention relates to a web division winding device that winds around a winding core at front and rear winding positions, and particularly to a device that has a mechanism for carrying out a winding roll.

(Prior Art) Conventionally, as a web division winding device of this type, for example, a center drive type sheet winding device with a slitter that vertically cuts a single sheet strip into a plurality of strips and winds the strips around a plurality of cores at the same time. In addition, each of the longitudinally cut sheet bands is wound around, and a common receiving roller at a fixed position for distributing to the plurality of cores, and the respective cores are supported at the upper end, and the common receiving rollers are contacted with the common receiving rollers to rotate. A plurality of pairs of oscillating supports, each of which is wound as a sheet roll by driving, and whose intervals are adjustable, an actuator attached to each pair of the oscillating supports for adjusting the external contact pressure between the core and the receiving roller, and the oscillating body. The magnetic powder clutches for controlling the sheet tension, which are intervened and equipped in the transmission mechanism that reaches the tip from the base of each pair of dynamic supports, and the tilt angles of each pair of the above-mentioned swinging supports, which detect the tilt angle due to the increase in the roll diameter of the sheet roll. Winding diameter detector There is a feature that it is provided with a step and each control device for automatically controlling the transmission torque of the magnetic powder clutch to a value suitable for each sheet roll winding diameter by the signal current of the detecting means. (See Japanese Patent Publication No. 53-33711) Further, a large number of winding rolls supported by independent support arms are pressed against a single common contact roller by a contact pressure adding mechanism provided on each support arm, and wound. The take-up roll, the contact roller, or both are driven so that the slit strip is wound around each take-up roll via the contact roller, and each supporting arm is vertically supported with respect to the common contact roller. It is pivotally supported on one common support so that it can swing back and forth in a smaller angle range, and swing displacement of each support arm is detected as a representative or average as the winding diameter of each winding roll increases. Based on the detected value, the common support base is positively controlled automatically in the horizontal direction from the common contact roller so that the winding roll support arms as a whole always maintain a substantially vertical support state. There was also what was to retract. (Refer to Japanese Examined Patent Publication No. 55-293) Then, the winding roll completed with these devices is connected to the touch roller of the support arm by tilting the support arm together with the common support base in the direction opposite to the touch roller. It had been swiveled out onto the cradle prepared in the space on the other side.

(Problems to be solved by the invention) However, among these conventional web division winding devices,
The former is unstable because it supports a heavy winding roll (sheet roll) on the upper end of the swing support.
During high-speed operation, the take-up roll dances on the touch roller, causing the support arm to vibrate back and forth, and the contact pressure between the take-up roll and the touch roller tends to fluctuate drastically. In some cases, the take-up roll may momentarily float above the touch roller. When the take-up roll and the touch roller come into contact with each other with a required contact pressure, the amount of air taken up between the take-up web and the web layers of the take-up roll is adjusted during take-up, and the take-up roll becomes uneven due to uneven web thickness. The unevenness of the end surface of the take-up roll, which is caused by the deformation and the reduction of the friction coefficient between the web layers of the take-up roll due to the air table effect, is prevented. However, as described above, the contact pressure between the take-up roll and the touch roller fluctuates drastically. As a result, the amount of air taken up between the web layers of the take-up roll is not adjusted properly, the take-up roll is deformed, and the end face of the take-up roll is not uniform, and the quality of the take-up roll is significantly deteriorated. Causes a problem of losing the product value of the winding roll.

The latter of the above-mentioned conventional web division winding devices is such that the supporting arm is pivotally supported on the common supporting base, the supporting arm is maintained in a substantially vertical state, and the common supporting base is horizontally moved from the common contact roller. Unlike the former, the core on the support arm is separated from the touch roller according to the growth of the take-up roll by positively retracting it, but the core is supported on the upper end of the pivotally supported support arm as in the former. Therefore, the same problem as the former occurs.

It has been known for a long time to use an oil damper in order to suppress vibration of a swing support (support arm) for supporting a winding core. However, when the winding speed is high, the oil damper is used. With the anti-vibration device using
It is not possible to sufficiently suppress the vibration of the conventional swing support (support arm), and not only the swing support (support arm) but also the vibration of the entire winding device can be added to form a high-quality winding roll. I couldn't do it.

When the take-up roll is further completed, the take-up roll is swiveled out onto the prepared receiving stand in the space on the side opposite to the touch roller of the swing support arm (supporting arm), but the receiving stand is
Since it is provided in the work place of the worker, the winding roll is carried out to the work space of the worker. If there is a take-up roll in the work space, it interferes with the take-up preparation work such as mounting a take-up core on the take-up device for the next new take-up, and the take-up roll on the receiving table is further removed. Since it is necessary to carry out the winding preparation work after moving to the place, it becomes difficult to carry out the winding preparation work in a short time. In addition, it is not preferable for the arm supporting the winding roll to fall into the work space in order to ensure the safety of the worker.

Recently, for example, as in the case of a polyester film that is the base of a video tape, when the surface is slippery and the end surface of the winding roll is uneven during winding, many webs are difficult to wind, and users are competing among companies. In order to increase the power, there has been a demand for a web-division winding device that has a high winding speed, a high operating rate, and high productivity of high-quality winding rolls. However, the conventional web division winding device could not sufficiently meet the demand of this user.

(Means for Solving the Problem) Therefore, according to the present invention, while dividing the web into a plurality of lines by a slitter, the divided webs are passed through a touch roller provided at a fixed position, and each of the webs is wound at the front and rear winding positions. In a web division winding device that winds around a winding core to make a winding roll, a guide surface that is provided in each of the front and rear winding devices so as to be linearly movable in the longitudinal direction of the web, and extends parallel to the width direction of the web. A space adjusting base having a projection arm part that is slidably engaged with the guide surface and is mounted on the space adjusting base to extend upward and project to the touch roller side. And a hanging arm that is pivotally supported by the protruding arm of the support and that detachably supports the winding core below the pivot point and at the height of the touch roller. Set on support The contact pressure applying mechanism that pushes the drooping arm toward the touch roller side, the drive mechanism that moves the distance adjustment table in the longitudinal direction of the web, and the commanding command to the drive mechanism during winding, and the drooping arm. As the winding roll of the divided web wound on the winding core grows so as to stay within the swing angle of
A control device for controlling the amount of retreat of the space adjusting table and a touch roller side of the support, and a space provided below the core support point of the hanging arm, and supported by the hanging arm. It is characterized in that it is provided with a carry-out mechanism for carrying out the completed winding roll on the winding core from that position to the side of the web division winding device as viewed in the longitudinal direction of the web.

Also, while dividing the web into multiple slitters,
In the web division winding device, which distributes the divided web to the front and rear winding positions via the touch rollers and winds it around each winding core, moves linearly in the longitudinal direction of the web at the front and rear winding positions. And a space adjusting base having a guide surface that is provided so as to extend parallel to the width direction of the web, and is slidably engaged with the guide surface to be attached to the space adjusting base and extend downward, A core support device positioned near the end and supporting a core at the same height as the touch roller at the lower end thereof, and a winding roll wound on the core support device, and a space below the core roll support device. And a carry-out mechanism for carrying out from the winding position.

(Operation) Since the core support point is located below the pivot point of the hanging arm, the hanging arm suspends and supports the winding roll from the support. 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 posture even if the hanging arm tilts from the vertical posture, thus stabilizing the take-up roll. Will be easier. When the take-up roll is supported on the upper end of the arm whose lower end is pivotally supported as in the conventional case, the gravity acting on the take-up roll causes the arm supporting the take-up roll to move even if the arm tilts slightly from the vertical posture. It is not easy to stabilize the support of the take-up roll because it works to tilt more. As the weight of the take-up roll increases, it becomes more difficult to stabilize the take-up roll. However, when the winding roll is supported by being suspended by the hanging arm, the larger the weight of the winding roll is, the more stable the winding roll can be.

The spacing adjustment base slides the support to position it so as to accommodate changes in the division position of the web. In addition, the space adjustment base moves linearly to support the support stably, suppress the vibration of the pivot point of the drooping arm, and retract the space from the touch roller. Further, by retracting the winding core supported at the same height as the touch roller from the touch roller by a horizontal linear motion, the winding tension of the divided web at the contact point between the touch roller and the winding roller and the winding The gravity of the take-up roll acts vertically, does not affect the contact pressure between the touch roller and the take-up roll, and the direction of the contact pressure between the touch roller and the take-up roll is always constant. Even if it grows, it is not necessary to correct the pressing force by the contact pressure applying mechanism. Since the conventional arm for supporting the core is pivotally supported on the support base provided on the lower side of the core, the arm and the contact pressure imparting mechanism or the oil are compared with the distance between the pivot and the core supporting point. The distance of the engagement point with the damper is extremely small, and the fluctuating force acting on the core support point due to slight deformation of the take-up roll and eccentric rotation causes the contact pressure applying mechanism of the arm and the engagement point with the oil damper. However, the contact pressure applying mechanism and the oil damper could not stably maintain the posture of the arm for supporting the winding core, because the action would be expanded several times. However, in the structure in which the support is provided along the hanging arm that supports the winding core of the present invention, the distance between the pivotal fulcrum of the hanging arm and the engagement point of the contact pressure imparting mechanism or the like is adjusted as necessary. The size near the distance between the fulcrum and the core support point is selected, or a size larger than that is provided to simplify the provision of the contact pressure applying mechanism. Providing the support so as to project from the gap adjusting base to a position higher than the height of the support point of the winding core increases the height of the mechanism for supporting the winding core, and rather supports the winding roll. It seems to be unstable,
As described above, the support of the winding roll is stable, and the control of the contact pressure between the winding roll and the touch roller is simplified. Then, when the take-up roll is supported stably and 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. The eccentricity-corrected take-up roll rotates more stably.

The carry-out mechanism supports the take-up roll released from the hanging arm and sends it to the side of the device through the space on the touch roller side of the support.

Similarly, when the winding core is supported on the lower end of the winding core supporting device extending downward from the space adjusting base, the winding roll is similarly stabilized. The take-out mechanism receives the take-up roll in a space below the winding core support device, and moves from that position to the take-up roll take-out position outside the take-up device. Since the carry-out mechanism can move to the space below the core support device and stand by even during winding, the next winding preparation can be performed immediately after the carry-out mechanism moves from the space below the core support device.

(Embodiment) FIG. 1 and FIG. 2 show a first embodiment of the present invention. FIG. 1 is an elevational view showing an outline of a web division winding device according to the present invention, and FIG. 2 is a plan view of the same.

The web W fed from an unillustrated original roll or the like is guided to the slitter 2 through the group of guide rolls 1 and divided into a plurality of lines by the slitter 2. Near the slitter 2, there are winding positions which move forward and backward in the longitudinal direction of the web W, that is, in the left-right direction according to FIG. 1, and between these front and rear winding positions, there is a fixed position at a certain height. According to this embodiment, the two touch rollers 3, 3 are arranged in parallel at the same height. The touch rollers 3 and 3 each have a length slightly larger than the width of the web W, and both ends of the touch rollers 3 and 3 have frames 4 and 4, respectively.
Are rotatably supported in parallel with the width direction of the web W. Each of the divided webs CW is wound around the winding core C alternately at the front and rear winding positions via the touch roller 3 on either side of the front and back to form a winding roll R. Then, the winding roll R grows while contacting the touch roller 3.

At the front and rear winding positions, winding devices for winding the divided web CW on the winding core C are provided so as to face each other, and have the same configurations and functions. Therefore, a detailed description will be given for one winding device. The winding device is provided with a space adjusting table 5 capable of linearly moving in the longitudinal direction of the web W so as to correspond to the web W. The interval adjusting table 5 needs to smoothly and stably move linearly so that vibration does not occur. Therefore, according to this embodiment, the space adjusting table 5 is fixed on the bases 6 arranged at three positions in the width direction of the web W as shown in FIG. 2, and each base 6 slides with the rails 7. Slide body 8 of linear motion bearing (commonly called linear way) composed of body 8
The slide bodies 8 fixed to each other are slidable on rails 7 fixed on a base 9 and extending horizontally in the longitudinal direction of the web W, and do not substantially move in a direction other than the sliding direction. Engaged. Further, the space adjusting table 5 has a guide surface 5a having a dovetail-shaped cross section and extending parallel to the width direction of the web W, as shown in FIG.

On the space adjusting table 5, there are mounted supports 10 respectively positioned near both ends of each winding core C arranged at the winding position for winding the divided web CW. The support body 10 extends upward from the space adjusting base 5 and has a protruding arm portion protruding upward to the touch roller 3 side.
With 10a. The base portion 10b of the support body is slidably engaged with the guide surface of the space adjusting base 5. The support 10 can be slid in the width direction of the web W on the space adjusting table 5 to move in parallel, and can be fixed to the space adjusting table 5 by the clamp device 11 at a desired position. Also support
The hanging arm 12 is pivotally supported by the protruding arm 10a. The hanging arm 12 can swing about an axis passing through the pivot point 02 and parallel to the touch roller. The pivot point 02 of the hanging arm 12 by the support 10 is located higher than the height of the touch roller 3, and the protruding arm portions of the pair of supports arranged on both sides of the core C are provided.
A pair of hanging arms 12.12 pivotally supported by each of 10a and 10a can rotatably support the winding core C in parallel with the touch roller 3 and at the same height as the touch roller 3. In order to prevent the posture of the winding core C parallel to the touch roller 3 from being impaired, the pair of hanging arms 12.12 are detachably fixed to the upper ends of the rods 13 that are common to both. By doing so, both of the pair of hanging arms 12.12 can move. The support body 10 is provided with a contact pressure applying mechanism 14 for pressing the core C against the touch roller 3 to urge the core C to adjust the contact pressure between the winding roll R and the touch roller 3 to a desired level. There is. The contact pressure applying mechanism 14 is engaged with the hanging arm 12 and can push the hanging arm 12 toward the touch roller 3. According to this embodiment, the contact pressure applying mechanism 14 includes an air-hydro tank (not shown) provided on the support 12 and a hydraulic cylinder 14a that engages the support 10 and the hanging arm 12 at the height of the core support point 01. And the compressed air pressure is changed to hydraulic pressure by the air-hydro tank to operate the hydraulic cylinder. When such a contact pressure imparting mechanism is used, the hydraulic cylinder 14a can provide the same function as the oil damper to suppress the vibration of the drooping arm and the function to adjust the contact pressure, thus eliminating the need for the oil damper. be able to.

When the number of divisions of the web W by the slitter 2 and the division width are changed, in the winding device, the support body 10 is arranged to support the winding core C having a length suitable for the divided web CW at a corresponding position. It is possible to wind the divided webs CW having various widths by attaching the webs CW to the appropriate positions above.

The winding core C supported between the pair of hanging arms 12.12 is mounted on one or both of the pair of supports 12 as a center drive by a rotation drive device (not shown), and is rotated by the touch roller 3. It is rotationally driven in combination with the surface driving by bringing the winding roll R into contact. The touch roller 3 can be finely changed by a prime mover (not shown) of the guide roller 1 with respect to the peripheral speed of the guide roller 1 via a continuously variable transmission mechanism (not shown). However, if necessary, a method of driving the core C by either center drive or surface drive may be adopted.

When the winding roll R around the winding core C grows, the winding core C separates from the touch roller 3. Therefore, assuming that the interval adjusting base 5 is fixed, only the hanging arm 12 separates the winding core C from the touch roller 3. It will tilt in the direction of
Since the tilting range of 12 is limited to a small range, it is not possible to obtain a take-up roll having a large outer diameter. Therefore, take-up roll R
Therefore, it becomes necessary to retract the space adjustment base 5 from the touch roller 3 as the growth of the. Therefore, according to this embodiment, two screw rods 16 screwed into the screw receiving member 15 of the space adjusting base 5 are provided.
And a motor 17 capable of rotating the screw rod 16 in a forward and reverse direction.
And a drive mechanism 19 composed of a rotation transmission mechanism 18 for transmitting the rotation of the motor 17 to both screw rods 16 so that they can rotate synchronously, and it is provided on the base 9. By driving the drive mechanism 19, the space adjusting table 5 can be moved back and forth in the longitudinal direction of the web W along the rail 7. Also, during winding, 12 drooping arms
Drive mechanism in order to keep the tilt angle of
A control device (not shown) for instructing 19 to control the amount of retreat of the space adjusting table 5 is provided. The control device receives a signal of the diameter of the winding roll R from the device for detecting the diameter of the winding roll, commands the amount of retreat according to the signal of the diameter of the winding roll R, detects the tilt angle of the drooping arm 12, In response to the detection signal, a command to slightly correct the amount of retreat is issued, and the interval is adjusted so that the swing angle of the drooping arm 12 is kept within a predetermined small range and the drooping arm 12 is maintained substantially vertically. The table 5 can be smoothly retracted.

The divided web CW having a predetermined length is wound around the winding core C in the space on the touch roller 3 side of the supporting body 10 and below the winding core supporting point 01 of the hanging arm 12. A unloading mechanism 20 is provided for unloading the completed winding roll R from the position to the side of the web division winding device as viewed in the longitudinal direction of the web W. According to this embodiment, the carry-out mechanism 20 comprises a conveyor device 21 for moving the take-up roll R in the longitudinal axis direction thereof, and a lifting device 22 for moving the conveyor device 21 up and down. The lifting 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. By the function, the conveyor device 21 can be moved in the longitudinal direction of the web W. Since the completed take-up roll R is supported by the hanging arm 12, it is only necessary to position the conveyor device 21 below the take-up roll R and release 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 division winding device will be described.

The core C is supported by the hanging arms 12 of the front and rear winding devices so that the slits 2 divide the web W at appropriate positions, and the drive mechanism 19 advances the gap adjusting table 5 to move each core C to the touch roller 3. It is placed at the winding start position where it comes into contact and the leading end of the divided web CW is stopped on each winding core C, and then winding is started. At this time, the conveyor device 21 is evacuated from the support body 12, the space adjusting table 5 and the like by the elevating device 22 of the carry-out mechanism 20. When the winding operation is started, the web W is fed out and the winding core C is driven to rotate, so that the web W moves toward the slitter 2
It is wound by the front and back winding devices while being divided by. During winding, the contact pressure applying mechanism 14 presses each winding roll R against the touch roller 3 with a desired pressing force, and the contact pressure between each winding roll R and the touch roller 3 is individually controlled. When the take-up roll R grows, the space adjusting bases 5 of the front and rear take-up devices are moved backward in the opposite directions by the action of the drive mechanisms 19 and the control device, and the cores C arranged at the take-up position.
Are collectively separated from the touch roller 3 for each winding position on one side. Further, the winding tension of the divided web CW is also individually controlled via the drive means of the winding core C. When the take-up roll R is completed, the space adjusting table stops moving backward at a predetermined position, the lifting device 22 moves, the conveyor device 21 is attached directly below the take-up roll, and the lifting device 22 raises it. Supports the lower surface of the winding roll R. Then, after the hanging arm 12 releases the take-up roll R, the space adjusting table 5 is retracted,
The support 10 and the hanging arm 12 are retracted from the winding roll R on the conveyor device 21 to create a space for moving the winding roll R in the longitudinal axis direction. Next, the conveyer device 21 is operated at the take-up roll receiving position or at a required height to feed the take-up roll 3 to the side of the web dividing and winding device, that is, to the right in FIG. Of course, the divided web CW connected to the take-up roll R is cut before the conveyor device 21 operates. Immediately after the drooping arm 12 retracts from the winding roll R, the operator pulls the winding core C for the next winding from above the work floor 24 provided on the opposite side of the support 10 from the touch roller. It is possible to mount the take-up roll R on the conveyor device 21 and to change the position of the support as needed. Further, by using the conveyor device 21, it is possible to reduce the floor area on the side of the web dividing and winding device, which is necessary for carrying out the winding roll R.

FIG. 3 shows a second embodiment of the present invention. FIG. 3 is a schematic elevation view in which one winding device of the web division winding device is omitted. In this embodiment, the contact pressure applying mechanism 14 is composed of an air cylinder 14c, and the oil damper 25 is engaged with the lower end of the drooping arm 12 extending further below the core support point 01. This is different from the above-described embodiment in that only one roll is commonly provided to the winding roll R at the winding position. According to this embodiment, the pivot point 02 of the drooping arm 12 and the oil damper are determined from the distance between the pivot point 02 of the drooping arm 12 and the core support point 01.
By increasing the distance between the engagement points 03 of the 25, even the small oil damper 25 can effectively suppress the vibration of the drooping arm 12. FIG. 4 shows a third embodiment of the present invention. FIG. 4 is a schematic elevation view in which one winding device of the web division winding device is omitted. In the case of this embodiment, the support 10
Gradually bends to project the protruding arm 10a at the upper part, and the base 10b and the space adjusting base 5 are directly below the hanging arm,
The discharge mechanism 20 can be moved parallel to the longitudinal axis of the take-up roll R, and the take-out mechanism 20 can move in parallel with the direction opposite to the touch roller 3. A movable base 26 that is on standby at a side standby position as viewed in the longitudinal direction of the web W and that moves from the standby position below the winding roll R supported by the hanging arm 12 when the winding roll is unloaded. ， With lifting device 22 mounted on this movable base 26,
This is composed of a receiving table 27 mounted on the lifting device 22, and further, the lifting device 22 raises the receiving table 27 to receive the winding roll on the receiving table 27, and then lowers the receiving table 27. For example, first, the winding roll is attached to the position shown by the chain double-dashed line in FIG. 4 and then the movable table 26 is moved to the standby position to carry out the winding roll R. Different from the example. According to this embodiment, it is not necessary to increase the moving distance of the space adjusting base 5, and the operation of the drive mechanism 19 thereof is simplified. In addition, if the carry-out mechanism 20 is moved to the standby position, the empty space can be used, which facilitates maintenance and inspection.

FIG. 5 shows a fourth embodiment of the present invention. In this embodiment, a web having a relatively small thickness unevenness is wound,
The take-up roll R is also difficult to deform. Therefore, the hanging arms 12 forming a pair and supporting the winding core C can be independently swung. Therefore, a common rod is not fixed to the pair of hanging arms 12 as in the above-described embodiment. Then, the take-up roll R is driven by the contact pressure imparting mechanism 14 such as a bellowram cylinder, a low-friction cylinder or the like, to which air of adjusted pressure is supplied.
The contact pressure with the touch roller 3 is precisely adjusted to a desired magnitude.

In the embodiments described so far, the rails on the base support the spacing adjustment base, and the hanging arm is pivotally supported on the tip of the support body extending upward on the spacing adjustment base, and below the pivot point. The winding core is supported in a state of being suspended via the hanging arm. Similarly to this, the web core is supported in a suspended state, but a web division winding device having a structure slightly different from those of the previous embodiments will be described below.

This web division winding device divides the web into multiple strips with a slitter, distributes the divided webs to the front and rear winding positions via a touch roller, and winds around each winding core. ， It is the same as the embodiment described so far. In this device, it is desirable to select the height of the support point of the winding core to a height that is convenient for the winding preparation work and the take-out of the winding roll. This device is provided with beam-like spacing adjustment bases above the winding cores at the front and rear winding positions, respectively. This spacing adjusting table has a guide surface extending parallel to the width direction of the web, and is provided so as to be linearly movable horizontally in the longitudinal direction of the web. To provide the space adjusting base in this way, for example, machine frames are arranged on both sides of the space adjusting base in the width direction of the web, and the rails similar to those in the above-described embodiments are attached to the machine frames and the rails are attached to the rails. Either both ends of the space adjustment base should be fixed to the mating slides and supported at both ends, or a gate-shaped machine frame with a required height that straddles the web should be installed, and a plurality of undersides of the beam in the center of this machine frame should be used. The rails may be attached at a predetermined interval in the width direction of the web, and the interval adjusting base may be fixed to the slide body that engages with the rails and supported at three or more positions, or an appropriate means may be used as necessary. At least one pair of core support devices is slidably engaged with the guide surfaces according to at least the number of cores at the winding position, and the space is adjusted to extend downward. are doing.
Each core support device is positioned near the core end at the winding position, and the core can be supported on the lower end of the core support device at the same height as the touch roller. The winding core support device, as in the above-described embodiment, includes a support body fixed to the gap adjusting base during winding, and a hanging arm that supports the winding core so that the winding core can be slightly moved with respect to the support body. Alternatively, it may be a structure integrated with the space adjustment base, which supports the core so as not to move with respect to the space adjustment base during winding. When the core support device is integrated with the space adjustment base, each core has its own touch roller to individually adjust the contact pressure between the touch roller and the take-up roll. A contact pressure applying mechanism may be provided on the device side so that each touch roller can be individually pressed against the take-up roll with a desired pressing force. Since each winding core is supported by the winding core support device at an appropriate height in a state of being suspended from the space adjustment table, a space can be provided between the take-up roll wound on the winding core and the floor. . The device is equipped with a take-out roll unloading mechanism that can enter the void. The carry-out mechanism can receive the take-up roll wound by the core support device in the space below and take it out from the take-up position. An example of this carry-out mechanism will be described below. That is,
The carry-out mechanism is equipped with a bogie at each of the front and rear winding positions. The trolley is provided with a take-up roll receiving section having a width capable of collectively receiving each take-up roll wound at the take-up position.
The carriage is moved on the floor in the longitudinal direction of the web so that the take-out roll carry-out position outside the take-up device can be located at the take-up roll receiving position in the space below the core support device. Before releasing the completed winding roll from the winding core support device, the lower surface of the winding roll is supported by the winding roll receiving part provided on the trolley so that the winding roll does not receive a drop impact when the winding roll is released. For this reason, it is preferable that the carriage be equipped with an elevating device for elevating the take-up roll unit. According to the carry-out mechanism of this embodiment, when the bogie is prepared at the take-up roll receiving position during winding and the take-up roll is completed and passed from the core support device to the take-up roll receiving section on the bogie. ， The trolley immediately moves to the take-up roll carry-out position. As soon as there are no carts at the winding position, the next winding preparation work can be performed and winding can be started. Then, the carriage that has finished carrying out the take-up roll is again prepared at the take-up roll receiving position in the empty space below the core support device during the take-up. Note that the carry-out mechanism is not limited to this embodiment, and may be the one provided with the conveyor device as described in the above-mentioned embodiments, for example. When the winding cores are supported by the respective winding core supporting devices and the winding is started, the front and rear interval adjusting bases are driven by the driving mechanism in directions away from each other,
It moves in the longitudinal direction of the web according to the increasing amount of the radius of the winding roll, and separates the core from the touch roller together with the core supporting device.

Although the present invention has been described above with reference to a few embodiments, various modifications can be made within the spirit of the present invention. For example, the number of supports provided in advance on the space adjusting table may vary depending on the division specifications required for the web division winding device. Alternatively, the web may be unwound via a traveling path provided below the winding device. The direction of the linear movement of the space adjustment table is not only completely horizontal, but may be slightly inclined from horizontal as long as it does not hinder the movement. Also, the center height of the touch roller and the height of the core support point are
As long as the fluctuation of the winding tension can be ignored,
You may make it substantially equal. Further, the hanging arm is not necessarily provided in a completely vertical position, but may be in a substantially vertical position. A hydraulic servo mechanism or the like may be used as a drive mechanism of the space adjusting base, or a known control device may be used as a control device for instructing the operation of this drive mechanism. Further, the touch roller may be individually provided for each of the divided webs.

The carry-out mechanism may be composed of a transfer robot provided for each take-up roll, or may be a type in which the take-up roll is dropped by a very short distance to receive it.

(Effect of the Invention) According to this invention, the vibration of the winding device is suppressed. Further, the adjustment of the contact pressure between the take-up roll and the touch roller is simplified. Therefore, the contact pressure between the take-up roll and the touch roller is stable and accurate during the take-up, and the take-up speed can be increased without causing defects such as unevenness of the end surface of the take-up roll. . Further, it is possible to obtain a high-quality take-up roll even in the take-up in which the take-up roll becomes very heavy by increasing the take-up length. Furthermore,
The unloading mechanism makes it possible to automate the unloading work of the completed take-up roll, and the take-up preparation work can be performed while unloading the take-up roll. It can be shortened. Therefore, the productivity of the web division winding device is significantly improved. Further, it is possible to enhance safety in the take-out roll carry-out work and the take-up preparation work.
