Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a strip-shaped sheet of plastic film, paper, metal foil or the like, which is divided into a plurality of lines by a slitter and distributed to both sides, and wound around a center-driven core. A take-up sheet winding device, in particular, each of the divided strip-shaped sheets is taken up around each winding core supported by a pair of winding core supports, and a touch roll is attached to a sheet roll formed around the winding core. The present invention relates to a sheet dividing and winding device of a type that winds while making contact with a sheet.

(Prior Art) Conventionally, in a sheet split winding device of the above type, as disclosed in, for example, Japanese Patent Publication No. 45-20644 and Japanese Patent Publication No. 55-293, the winding core is swung about one point. It is generally supported on the tip of a possible core support arm. Also, Japanese Examined Sho 57-2
As shown in FIG. 1 of Japanese Patent No. 8658, there is also a device for supporting a core on a core support movably placed on a frame via a carriage.

(Problems to be Solved by the Invention) In a sheet dividing and winding device of the type described above, for example, when a belt-shaped sheet such as a plastic film whose surface is easily stretched smoothly is wound, the end surface of the wound sheet roll may be uneven. Many. Also, if it becomes too heavy, the sheet roll will collapse during winding and the winding must be interrupted.

Conventionally, such inconvenience occurs because the sheet wound on the sheet roll slips and shifts in the width direction during winding, and air is entrapped in the sheet layer having poor air permeability and overlapped in the sheet roll. It is understood that the coefficient of friction between the sheets is reduced. Therefore, the touch roller is pressed against the outer periphery of the sheet roll being wound with a required contact pressure to adjust the amount of air to be wound, thereby preventing the sheet from being laterally displaced.

However, in recent years, for example, in the case of strip-shaped sheet winding having a very slippery surface such as a polyester film whose surface is treated to have a mirror surface, not only the contact pressure but also the winding tension and the winding position. No matter how the sheet feeding tension is controlled, it is impossible to prevent the above-described sheet lateral deviation phenomenon. In particular, it is very difficult to wind a very thin sheet or a highly stretchable and slippery sheet with good quality.

However, recently, even for the above-mentioned strip-shaped sheet which is difficult to be wound up, it is strongly required to be wound up on a large-diameter sheet roll at high speed.

However, in such a case, a sheet roll having good winding quality cannot be obtained. Therefore, conventionally, when winding a belt-shaped sheet which is difficult to wind as described above, the winding speed is set as low as possible to obtain a sheet having a small outer diameter. Roll up into a roll. Therefore, the productivity of the conventional sheet division winding device is poor, and improvement in productivity cannot be expected.

That is, conventionally, an attempt has been made to apply a proper contact pressure on the assumption that there is no vibration of the winding device, and the cause of the sheet roll end face non-uniformity is considered to be the incompatibility of the contact pressure, the winding tension, and the supply tension. Therefore, the true cause of the above-mentioned inconvenience could not be grasped. Therefore, the attention has been focused only on the contact pressure control, the winding tension control, and the like, and there has been a situation in which it is not possible to obtain a sheet split winding device that can be operated at a higher speed.

However, recently, it has been found that the cause of the above-described winding failure is vibration of the winding mechanism.

In the winding mechanism, the eccentric rotation and unbalance of the seat row are the main vibration sources.The eccentric rotation and unbalance of the sheet roll are caused by the eccentricity of the shaft holding the core and the eccentricity of the core around this shaft. This vibration source cannot be completely eliminated because it is caused by the deformation of the sheet roll due to the accumulation of the support and the uneven thickness of the sheet. For this reason, the higher the speed, the more significant the vibration. As a result of the experiment, it was confirmed that the swing width of the swingably supported core support is, for example, 15 μ to 35 μ. This swing width adversely affects the contact pressure control.

Further, when winding is performed while the sheet roll and the touch roller are in contact with each other, it is necessary to separate the core and the touch roller from each other in accordance with the thickness of the sheet low. And
In order to prevent deviations in the width direction of the sheet and prevent variations in the winding quality, it is good practice to divide the strip-shaped sheet with a slitter and then wind it through the shortest possible travel route. To this end, it is preferable that the touch roller is provided at a fixed position and the core is separated from the touch roller. Therefore, the winding mechanism requires a minimum of moving parts for moving the winding core.

Therefore, although it is impossible to completely reduce the vibration of the winding mechanism to zero, the vibration must be suppressed to a small degree even in high-speed operation.

However, the conventional sheet split winding device that supports the winding core on the tip of the winding core supporting arm that can swing about one point has the following disadvantages.

That is, in the sheet dividing and winding device described in Japanese Patent Publication No. 45-20644, the core support arm is tilted by the swing drive mechanism according to the winding weight of the sheet roll, and the core is separated from the touch roller. In order to obtain a sheet roll having a large outer diameter, the length of the core support arm must be increased so that the core can be sufficiently separated from the touch roller. Therefore, the core support arm has a structure that is easily bent.

Further, only the swing drive mechanism of the core holding arm has the function of resisting the swing of the core support arm, and all swing forces generated in the core support arm itself are supported by the swing drive mechanism. There is a need. Further, the distance between the point of action of the driving force of the swing drive mechanism on the core support arm and the swing fulcrum of the core support arm becomes shorter than the distance between the core support point and the swing fulcrum. The force acting on the supporting point is expanded and acts on the swing drive mechanism.

Further, even if there is a small amount of play in the engaging portion between the swing drive mechanism and the core support arm or the swing fulcrum, the play is enlarged at the core support point at the tip of the core support arm and becomes a large play.

The device described in Japanese Patent Publication No. 55-293 has a structure in which the lower end of the core support arm is pivotally supported on a common support base and a heavier sheet roll is supported on the upper end thereof. The common support base is retracted from the touch roller so that the posture of the core support arm is kept substantially vertical according to the increase in the winding weight. And, the common support base does not have a function of keeping the core support arm firmly and vertically. Also, a vibration preventing mechanism for the core support arm such as an oil damper can be provided,
It merely delays the swing of the core support arm and cannot reliably maintain the posture of the core support arm.

Therefore, the above-mentioned Japanese Patent Publication No. 45-20644 and Japanese Patent Publication No. 55-293.
The core supporting arm of the sheet split winding device described in Japanese Patent Publication is liable to slightly swing during winding, and the core is likely to be in a vibrating state.

Therefore, during winding, the core vibrates and the contact between the sheet roll and the touch roller becomes unstable, the function of preventing air entrapment between the sheet layers by the touch roller does not work, and a large amount of air is entrapped between the sheet layers. In addition, the coefficient of friction between the sheet layers is remarkably reduced, and the sheet roll is impacted, causing a problem that the sheets in the sheet roll slip and cause uneven end faces and collapse of the roll.

Further, in the above-described conventional apparatus, the wound sheet roll is carried out by inclining the core support arm toward you. However, since the front side of the core support arm is a work area for the winding preparation by the worker, the workability of the next winding preparation is poor, and the winding stop time becomes long, improving the productivity. I can't.

Further, the tilted core support arm may pose a danger to an operator.

Furthermore, the device shown in FIG. 1 of Japanese Patent Publication No. 57-28658 is
No consideration was given to unloading the sheet roll,
It takes time and effort to prepare for winding, which is inefficient. Further, since the core is supported by the core support that is movably placed on the frame via the carriage, it is not possible to expect that the vibration of the core during winding is sufficiently suppressed.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a highly productive sheet winding device capable of winding a belt-shaped sheet having a slippery surface at high speed.

(Means for Solving the Problems) In order to achieve the above object, the present invention is directed to a center-driven core that divides a strip-shaped sheet supplied from above into a plurality of strips by a slitter and distributes the strips to the winding positions on both sides. In a sheet split winding device that winds around a sheet, a touch roller that is provided in a fixed position that contacts the outer periphery of the sheet roll that is being formed on the core, and a sheet length that is constrained in the sheet width direction and the vertical direction. Has a movable base that is slidable along the winding position and a space that communicates with the touch roller below the mounting position of the core. A core support that is restrained in the direction and slidably attached in the sheet longitudinal direction, and a contact pressure adding mechanism that pushes the core support toward the touch roller.
A drive mechanism that retracts the movable table from the touch roller in accordance with the winding weight of the sheet roll, and is arranged in a space below the core support portion of the core support, the sheet roll in the width direction of the belt-shaped sheet. The present invention is characterized by comprising a carrying device for carrying, a waiting position, and a moving mechanism for moving the carrying device to a sheet roll receiving position in the empty space.

(Operation) Since the strip-shaped sheet is supplied to the slitter from above and the divided sheets are distributed to the front and rear winding positions, the strip-shaped sheet does not pass below the winding position. Therefore, the movable base on which the winding core support is placed can be stably provided along the base or the ground, and the mechanism for supporting the winding core can be made to have a structure that is extremely resistant to vibration.

The core support is attached to the movable table so as to be slidable in the sheet longitudinal direction while being restrained in the sheet width direction and the vertical direction so that the contact pressure between the touch roller and the sheet roll can be individually adjusted. In order to separate each core support from the touch roller according to the roll weight of the sheet roll, the core is constrained in the sheet width direction and the vertical direction so that it can slide in the sheet longitudinal direction. There is no swinging part in the mechanism for retracting that tends to cause vibration. The touch roller is provided at a fixed position. Therefore, during winding, the vibration of the winding core is suppressed to a small degree, and the contact pressure between the sheet roll and the touch roller is kept stable. Therefore, the frictional force between the sheet layers does not become unstable, and the inconvenience such as lateral slippage of the sheet during winding is eliminated.

Since the winding core support has a space communicating with the touch roller side below the winding core mounting position, the sheet roll conveying device can be positioned below the wound sheet roll. Then, the transport device can send the sheet roll supported by the core support body to itself by the action of the moving mechanism. Thereby, each sheet roll can be delivered onto the transport device without swinging the core support.

(Embodiment) FIG. 1 and FIG. 2 show an embodiment of the present invention. FIG. 1 is an elevational view of a sheet dividing and winding device according to the present invention, and FIG.
The figure is a plan view of the same.

The width sheet S travels in a sheet traveling path above the winding work space, reaches the grooved roller 1 through the roller group, and is divided into a plurality of lines by the slitter K. Then, the divided sheets are distributed from the grooved roller 1 to the front and rear winding positions via the touch roller 2 which is rotatably supported at a fixed position, and are supported in parallel with the touch roller 2 so as to support a pair of cores. A sheet roll R is wound around each winding core C supported by the tip of the body 10.

In the right half of FIG. 1, the sheet roll R is wound up at the front winding position, and in the left half, the sheet roll R wound up at the rear winding position is passed by the unloading mechanism 24 to retract the core support 10. The state where it was made to show is shown. In addition, the chain line shown in the left half of FIG.
It shows a state at the start of winding when the winding core support 10 is advanced to bring the winding core C into contact with the touch roller 2. As the winding of the sheet roll R increases, the winding core C gradually separates from the touch roller 2 while keeping the contact between the touch roller 2 fixedly attached and the sheet roll R. Note that FIG. 1 shows a section taken along the line aa in FIG.

A guide mechanism on the base 11 along the front and rear winding positions.
12 longitudinal direction of the sheet (direction perpendicular to the sheet width direction)
The spacing adjustment base 13 guided by the above is provided as a movable base for allowing the core support 10 to be separated from the touch roller 2.

The guide mechanism 12 includes a rail 12a extending in the seat longitudinal direction,
A movable body (fitting member) 14a is slidably attached to the rail 12a so as to be restrained in the vertical and seat width directions. As shown in FIG. 3, the movable body 14a is fitted on the head of the rail 12a so as to prevent looseness that causes vibration. The rails 12a are fixed to the base 11, and are arranged at three positions in the seat width direction as shown in FIG.

As shown in FIG. 1, the space adjusting base 13 has a leg base 14 fixed to the lower part thereof. This leg base 14 extends along the rail 12a in order to enhance the stability of the space adjusting base 13.
The movable body 14a of the guide mechanism 12 is provided on the lower surface of the foot stand 14.
Is stuck.

Further, the space adjusting base 13 is provided with a dovetail-shaped protrusion 13a extending in the seat width direction on an upper portion thereof, and a base 27 which is slidably engaged with this and serves as a base of the core support 10. This stand 27
Even if the dividing position by the slitter K changes, the core support
In order that the core 10 can support the core C at a new position corresponding to each divided sheet, it can be moved in the sheet width direction on the space adjusting base 13 to be placed at a required position. Also, stand
27 is equipped with a clamp 15 for fixing it to the spacing adjustment table 13 during winding.

On the base 11, a drive mechanism 16 is provided for driving the space adjusting table in the guide direction of the guide mechanism 12. As shown in FIG. 2, the drive mechanism has a ball screw shaft 16a which is arranged in two places on the left and right in parallel with the rail 12a for each of the gap adjusting bases 13 on one side, and the ball screw 16a has substantially no problem. The screw member 16b is screwed with no backlash and has a small rotation resistance, and is fixed to the gap adjusting base 13.
During winding, a servo motor 16c that drives the ball screw 16a at a low speed, a motor 16d that drives the ball screw shaft 16a at a high speed and can rotate in both forward and reverse directions, and these motors 16c,
It comprises a differential gear mechanism 16e for transmitting the rotation of 16d to the ball screw shaft 16a, a transmission shaft 16f, and a bevel gear mechanism 16g.
Then, the left and right ball screw shafts 16a are synchronously driven, and can approach and separate in parallel with the space adjusting base 13, the winding core C, and the touch roller 2 at a fixed position. In addition, ball screw shaft 16a
Tries to stop the displacement other than the displacement of the distance adjusting base 13 due to its own rotation, so that even if a large force acts on the distance adjusting base 13 from the outside, the distance adjusting base 13 can be easily displaced by it. There is no.

A rack, a pinion 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 2 at the fixed position. Also, ball screw shaft 16a
Is not limited to two locations, and the motor
Other screw shafts can be used instead of 16c and 16d.

Further, if it is necessary to further mechanically ensure the parallel movement of the space adjusting base 13, not only the precision of the guide mechanism may be increased but also a well-known parallel movement mechanism may be supplementarily employed.

The core support 10 has a base 27 on the space adjustment base 13
Further, it is attached by a core support guide mechanism 28 so as to be restrained in the sheet width direction and the vertical direction and slidable in the sheet longitudinal direction.

According to this embodiment, the core support guide mechanism 28 is composed of a rail and a movable body extending in the seat width direction, similar to the guide mechanism 12 described above. This rail is fixed on the base 27, and the movable body is fixed on the lower part of the core support 10. The core support 10 is a sheet roll R that is being wound.
Even if there is a difference in radius, the sheet roll R can be slid with respect to the base 27 by a small distance so that each sheet roll R can be brought into contact with the touch roller 2 by absorbing the difference in radius. You can do it.

Therefore, the core C is movably supported on the base 11 without interposing a swingable member that easily causes vibration of the core C. In other words, during winding, the space adjustment base 13
The guide mechanism 12 can slide and retreat from the touch roller 2 in a fixed position in a state where the swing motion is suppressed, and the core support 10 is moved by the core support guide mechanism 28 with respect to the space adjusting base 13. It is possible to perform a sliding motion in the longitudinal direction to displace it while suppressing the swinging motion.

Therefore, the mechanism for movably supporting the core C has a function to support the core C even if the core C separates from the touch roller 2 during winding.
Vibration of the winding core C due to fine swinging of the winding core support 10 can be sufficiently suppressed.

It should be noted that each member of the mechanism for supporting and moving the core such as the core support 10 and the gap adjusting base 13 does not tune to the core even if a force that causes vibration is exerted on the core. Needless to say, it has a large weight and rigidity, and the mutual phases of the respective members other than the part that slides during winding are securely connected to each other so as to have a low height. Also,
When it is necessary to supplement the weight of the space adjusting table, it is possible to cope with the increase in the weight by, for example, assembling a reinforcing bar in the hollow portion of the member and filling it with cement. Further, the guide mechanism may be provided not only at three locations but also at more locations if necessary in order to suppress the deflection of the space adjustment base 13 and to be able to exert the anti-vibration function more.

Further, the table 27 is provided with a contact pressure adding mechanism 25 for pushing the core support 10 toward the touch roller 2 with a desired force during winding. Therefore, even if the winding core C is separated from the touch roller 2 all at once by retracting the interval adjustment base 13 from the touch roller 2 according to the winding weight of the sheet roll R,
Each pair of core supports 10, 10 has an individual contact pressure applying mechanism 25.
Since it can be pushed to the touch roller 2 side, the contact pressure between the sheet roll R and the touch roller 2 can be individually adjusted. The pressing force by the contact pressure adding mechanism 25 is controlled by a known contact pressure control device (not shown). As the contact pressure adding mechanism, for example, a low friction cylinder, a bellofram cylinder or the like can be used.

If the space adjustment base 13 is stopped at a fixed position during winding,
When the sheet roll R is thickened, the core support 10 is displaced with respect to the gap adjusting base 13 and exceeds the guide range of the core support guide mechanism 28. It cannot be adjusted. Therefore, the drive mechanism 16
A control device (not shown) detects the displacement of the core support 10 and feedback-controls it. The sheet roll R keeps the core support 10 at a substantially constant position of the interval adjusting base 13 during winding.
The space adjusting base 13 can be retracted from the touch roller 2 according to the winding weight of the.

The touch roller 2 is provided at the central portion of the front and rear winding positions in common with each core C at the front and rear winding positions, and the core C on each core support 10 is provided.
It is located at the same height as.

Further, a work floor plate 17 is stretched on the upper surface between the leg bases 14, 14 on the side opposite to the touch roller of the space adjusting base 13, so that it is easy to work on both sides of the winding position.

In the center of the dovetail-shaped protrusion 13a on the upper surface of the space adjusting base 13, a groove 13b is provided over the entire length of the space adjusting base,
A screw shaft 19 that can be rotated in the forward and reverse directions by driving the rotation drive mechanism 18 is placed in the groove 13b. Further, each core support 10,
The screw shaft 19 is provided with an engagement / disengagement mechanism capable of engaging / disengaging as appropriate, and by operating the engagement / disengagement mechanism to engage / disengage the screw shaft during normal rotation or reverse rotation of the screw shaft, the space adjustment table is mounted. Can be moved to a predetermined position in a short time.

Further, in order to keep the pair of winding core supports 10 integrated during winding, both ends of the stay member 26 are fixed and connected in this embodiment. The stay member 26 may not be used.

A publicly known core drive mechanism (not shown) that drives the core C to rotate around one or both of the pair of core supports 10 so that the divided sheets can be wound with a required winding tension. Is prepared.

In addition, the core support 10 has a portion projecting toward the touch roller 2 in the upper part, and a well-known winding core that supports the core C so that it can be removed at the tip of this projecting portion. A wick support is provided.

Further, in the space below the core support portion of the core support 10 on the side of the touch roller 2, that is, the core support 10, the space adjustment base 13,
The core support 10 between the mechanism for movably supporting the core C such as the guide mechanism 12 and the touch roller 2 and its supporting mechanism.
A carry-out mechanism 24 for carrying out the sheet roll R is provided in the space below the sheet roll R supported by.

In this embodiment, the carry-out mechanism 24 includes a conveyer 24a as a conveying device extending in the sheet width direction along the take-up position, a standby position where the conveyer 24a does not interfere with take-up, and a receiving position just below the sheet roll R. Conveyor 24 for attaching to position
It is composed of an elevating mechanism 24b for a and a moving mechanism having a lateral movement drive mechanism (not shown) for moving the conveyor 24a horizontally in the longitudinal direction of the sheet together with the elevating mechanism 24b. The conveyor 24a can convey the sheet roll R in the sheet width direction by the conveyance drive of a drive mechanism (not shown).

To explain the operating procedure of this device, as shown in the left side of FIG.
Each pair of core supporters 10 of the winding device before and after the rolled-up sheet roll R is transferred to the conveyor 24a and retracted to the solid line position.
First, attach a new winding core C to the upper attachment position. Then, after the sheet roll R is carried out by the conveyor 24a, the motor 16d of the drive mechanism 16 is operated at a high speed to move all the core support 10 toward the touch roller 2 in the fixed position,
The core C is brought into contact with the fixed touch roller 2 as shown by the chain line in the left half of FIG.

When the leading 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 becomes thicker. Meanwhile, contact pressure adding mechanism
While applying a required contact pressure between the sheet roll R and the touch roller 2 at the fixed position by 25, the servomotor 16c of the drive mechanism 16 is operated to move the core support 10 and the gap adjusting base 13
The winding core C is continuously retracted. Needless to say, if the contact pressure is continuously applied by the contact pressure applying mechanism 25, the separation of the interval adjusting base 13 may be intermittent.

Thus, when the sheet roll R is rolled up, the conveyor 24
By the action of the moving mechanism, a moves from the standby position shown by the chain line in the left half of FIG. 1 to the receiving position just below the center of the sheet roll R supported by the core support 10, and the sheet roll R Support from below. Then, each core support 10 releases the sheet roll R. As a result, the sheet rolls R at the winding position are collectively passed on the conveyor 24a. After that, the motor 16d of the drive mechanism 16 is operated, and the space adjusting base 13 and the core support 10 are attached to the positions shown by the solid lines in the left half of FIG. Then, the conveyor 24a
Conveys the sheet rolls R all at once and carries them out to the side of the winding position.

When the sheet dividing width is changed and 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 base 13 to be attached at corresponding positions. A well-known positioning drive mechanism may be used instead of manpower in order to move the core support pair to a desired position.

According to this example, a 12μ thick plastic film
When wound at a speed of 600 m / min, the vibration in the vicinity of the core support was within 5 to 10 μ. Moreover, there is almost no change from the beginning to the end of winding.

Although the position 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 of the guide mechanism 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 it is floated from the floor or the base and strongly supported. It is possible to guide through the fitting member slidably with the rails, or to directly guide the space adjusting base with the rails without using the leg bases. Also, use commercially available linear motion bearings (for example, Linear Way or Linear Roller Way manufactured by Nippon Thomson Co., Ltd., Infinite Linear Motion Bearing manufactured by Tsubakimoto Seiko Co., Ltd., LM Guide manufactured by THK Co., Ltd.) Guide to the guide surface and the mating surface via rolling elements such as wheels, or use the upper surface of the base as a sliding surface,
The lower surface of the space adjusting base may be directly slidably engaged with the guide to guide and support the space adjusting base by the guide mechanism. Further, the guide mechanism may be fixed on a base such as a touch roller and a guide roller which is provided independently of the base.

Further, the method of attaching the core support to the interval adjustment base is not limited to the above-described embodiment, such as using a commercially available linear motion bearing and slidingly engaging the core support, and the method of mounting the base that is the base of the core support is not limited. The fixing to the space adjusting base may be performed by using a bolt or other clamping mechanism, and is not limited to the one in which the core support is engaged with the upper side of the space adjusting base.

In the above-described embodiment, the winding core is separated from the touch roller in the horizontal direction, but it may be separated substantially horizontally.

The core support 10 shown in FIG. 1 is U-shaped and has a space below the sheet roll for receiving the conveyor 24a at the sheet roll receiving position. Is not limited to the U-shape, but is also an inverted L-shape, C-shape, etc.
It can be varied in consideration of the space for receiving the carry-out device.

Further, the sheet dividing and winding device may adopt a type in which the core is driven centrally, a type in which center driving, surface driving by a touch roller are used in combination, and the like depending on conditions. Further, as long as the touch roller is provided at a fixed position, one touch roller may be provided in common to each sheet roll at one winding position, that is, a total of two touch rollers may be provided at the front and rear winding positions. You may provide it separately for every.

Further, the present invention is not limited to a so-called slitter rewinder having a rewinding part of an original roll, but is also combined with a processing machine such as a coating machine or a laminating machine to divide a web sent while being processed in a processing step. It goes without saying that the present invention can also be applied to a sheet split winding device for finishing and an inline slitter rewinder directly connected to the web manufacturing process. As mentioned above, if you basically consider eliminating vibration as much as possible,
It is understandable that there are various ways to deal with them.

Further, the conveyor 24a shown in FIG. 1 is a belt conveyor, but other known conveyors may be used. Further, as long as it has a function of supporting the sheet roll and carrying it out in the sheet width direction, other transporting device such as a dolly may be used instead of the conveyor. In some cases, the conveyor can only be moved up and down and does not require lateral movement. Further, in order to move the conveyor in a horizontal posture, it is preferable to drive the left and right lifting mechanisms mechanically or electrically synchronously. In addition, in order to move the left and right lifting mechanisms simultaneously by the same amount, for example, a beam is provided in the middle between the two to form an integrated structure, or the common left and right shafts are rotated in the seat width direction at the bases of the left and right lifting mechanisms. It is also possible to support a pinion on this shaft, fix the pinion, and engage with a rack fixed on the base near the guide mechanism of the elevating mechanism or other known type of parallel movement mechanism as an auxiliary. it can.

Further, by supporting both ends of the beam-shaped conveyor 24a shown in FIG. 2 by the elevating mechanism 4b, the space of the winding area can be effectively used. However, the number and arrangement of the elevating mechanisms that support the conveyor may be appropriately selected as needed. The lifting mechanism may be a known device such as a gear jack or a hydraulic lifter as long as it has a function of lifting or lowering the conveyor by sliding or swinging.

Further, 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. The sheet rolls on the conveyor may be received not directly on the upper surface of the conveyor but indirectly via common or individual pallets. In that case, in order to prepare the pallet at the sheet roll receiving position on the conveyor, the conveyor may be provided with a mechanism for carrying it out to both the left and right.

If necessary, an elastic material may be attached to the receiving surface in order to prevent the sheet roll from being damaged when the sheet roll is received, or a buffer mechanism may be interposed in the elevating mechanism.

As the lateral movement drive mechanism, a known drive mechanism capable of moving the conveyor in the sheet longitudinal direction and setting it at 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.

The transfer of the sheet roll between the core support and the transport device may be performed at a position where the sheet roll is wound up, at a position slightly retracted from the position, or at the retracted end of the core support. . When the delivery is performed at the retracted end of the core support, the transport device receives the sheet roll, laterally moves to the touch roller side, and then starts transport to the machine side.

The winding core tube passing through the shaft or the winding shaft itself is used as a winding core, and the winding core support can support the lower surfaces of both ends of the winding core even if the winding core support releases the winding core. When clamps are provided on the outer peripheral surfaces of both ends of the core, the clamps may be first released, and then the sheet roll may be slightly lifted by the transport device and then the core support may be retracted.

There are various possible movements of the conveying device to the sheet roll receiving position, such as moving in the lateral direction and then ascending or obliquely moving, or first ascending to the receiving position.

(Effect of the Invention) According to the present invention, in the mechanism for supporting the core and separating it from the touch roller, the conventional swinging portion that easily causes vibration is eliminated, and the movable core support is mounted. Since the base is stably installed along the base or the ground and the touch roller is installed at a fixed position, vibration of the core is suppressed during winding, the contact pressure between the sheet roll and the touch roller is stable, and high quality is achieved. The sheet roll can be obtained at high speed.

Further, the transport device itself can go to receive the sheet rolls supported by the core support and collectively receive the sheet rolls at the winding position. Therefore, even if the core support does not swing, the sheet roll can be reliably delivered in a short time. Further, it is not necessary to provide a mechanism having a complicated structure for delivering the sheet roll between the core support and the conveying device.

Further, since the sheet roll is unloaded in the sheet width direction on the touch roller side of the core support, it can be unloaded with.
Moreover, the roll-out preparation work area on the side opposite to the touch roller is not affected by the sheet roll unloading, the winding stop time can be shortened, and the safety of the worker can be secured.

Therefore, if the sheet split winding device of the present invention is used,
Productivity is greatly improved.
