Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) A wide strip-shaped sheet of plastic film, paper, metal foil, etc. is divided into a plurality of narrow sheets by a slitter and distributed to the winding positions on both sides. In the sheet dividing and winding device, which winds the narrow width sheet guided to the core through the touch roller around each core that separates from the touch roller in accordance with the increase in the winding weight, the wound sheet roll is carried out. The present invention relates to a sheet dividing and winding device including a carry-out device.

(Prior Art) Conventionally, in this type of sheet split winding device, a swingable core support arm that supports a core at a tip portion thereof moves from a touch roller together with a core in accordance with a sheet roll winding weight during winding. After swinging and separating, after the sheet is wound onto the core, it is swung to the side opposite to the touch roller by the drive mechanism, and falls sideways. In some cases, the sheet roll is unloaded by handing over the sheet roll on a cradle. (Japanese Patent Publication Sho 53-3371
(See Japanese Patent Publication No. 1) (Problems to be solved by the invention) However, in order to start the next new winding, the sheet connected to the touch roller is cut from the sheet roll on the pedestal and the sheet roll is removed. By separating from the sheet split winding device, attaching a new core to the core support arm, and pivoting the core support arm to the touch roller side,
A new winding core is attached to the winding start position on the touch roller, the remaining sheet on the touch roller side is wound around the winding core, and the leading end of the winding is adhered to the winding core. When the sheet roll is placed on the pedestal that serves as the floor for performing such winding preparation work, the sheet roll interferes with workability and the work is difficult. After removing each roll from the pedestal, a new core is attached to each core support arm, so in the above-mentioned conventional sheet split winding device, the stop time becomes long, There was a problem that the operating rate was low. Some of the above-described sheet dividing and winding devices are capable of processing a strip-shaped sheet having a width of, for example, 8 m, and the weight of a sheet roll that is divided and wound may be several hundred kilograms. The operating rate decreases as the number of divided sheets increases and the weight of the sheet roll increases. In addition, the fall of the core support arm toward the work floor is not preferable for ensuring the safety of the worker.

Also, for example, when winding a sheet such as a plastic film having poor air permeability and a smooth surface, the sheet slides in the width direction during winding and the end face of the sheet roll is not uniform. Not only is the pressure and winding tension unsuitable, but the winding core moves back and forth during winding.
It was found that contact pressure control and winding tension control work effectively only after the vibration state of the core is prevented due to the vibration state of the core, which reciprocates in small directions in other directions. However, when the core is supported by a swingable core support arm,
There is a limit to increasing the rigidity of the core support arm itself, and further, there are spatial restrictions and the like, so that free swing of the core support arm is eventually restricted. The distance between the point where the driving force acts and the swing fulcrum becomes smaller than the distance between the swing fulcrum of the core support arm and the core support position, and the force acting on the core swings according to the principle of leverage. Since the driving force of the drive mechanism is enlarged at the point of action, the winding core mechanically tends to vibrate. Therefore, in the conventional sheet split winding device in which the core is supported by the swingable core support arm, the vibration state of the core during winding is suppressed, and the sheet roll is wound with good quality and at high speed. There was a problem that it was difficult to take. In order to prevent the core from vibrating during winding at the development stage of the sheet split winding device of the present invention, a mechanism for supporting the core and separating it from the touch roller is provided. The rigidity of the core support mechanism, such as the support body that supports the core without the rocking mechanism, is increased, and the core support mechanism is linearly guided laterally by the highly accurate sliding mechanism to form the entire winding section. It has been found that it is necessary to increase the rigidity of the. However, when the core support mechanism is linearly guided and separated from the touch roller, the take-out of the wound sheet roll cannot adopt the conventional carry-out,
The sheet roll must be carried out manually, or the sheet roll must be lifted and carried out by a hoist or the like provided on a carriage that travels on the sheet winding machine. Or a large-scale unloading device is required. Further, in the case of carrying out the sheet roll by swinging the conventional core support arm, the seat roll cradle may be always provided at a fixed position. However, when guiding the core support mechanism linearly in the lateral direction, The sheet roll carry-out device must be moved and positioned when the sheet roll is received from the retracted position, which does not hinder the movement of the core support mechanism, to the sheet roll receiving position. And the time required to move from the retracted position to the sheet roll receiving position is wasted.

(Means for Solving the Problems) Therefore, according to the present invention, a wide strip-shaped sheet is divided into a plurality of narrow sheets by a slitter and distributed to the winding positions on both sides, and according to the winding thickness of the sheet roll of the narrow sheet. In a sheet split winding device that winds the narrow sheet, which passes through the touch roller and is guided to the core, around each winding core that separates from the touch roller, the sheet dividing winding device is provided corresponding to each of the winding cores. A core-supporting mechanism in which a space-side protruding portion to the touch roller side and a core supporting body having a core attaching / detaching mechanism at the tip of the protruding portion are supported on a space adjusting base, and the core supporting mechanism is a strip-shaped sheet. A sliding mechanism that supports linear movement in the lateral direction at a right angle to the width direction, a movement drive mechanism that reciprocates the core support mechanism in the sliding direction of the sliding mechanism, and a right angle in the width direction of the belt-shaped sheet. Laterally A sheet roll, which is supported movably and vertically so as to be movable, is provided on the touch roller side of the core support mechanism and is lifted from below the protruding portion of the core support and is received, is conveyed in the width direction of the belt-shaped sheet. And a link mechanism that links the core support mechanism and the sheet roll unloading device.

(Operation) The core support mechanism does not have a swinging part in the direction away from the touch roller, is guided by the sliding mechanism, and linearly moves the core away from the touch roller in the lateral direction. A large moment acting on the core support mechanism from the sheet roll through the core and vertical and horizontal forces can be sufficiently supported by the sliding mechanism without rattling even if it is small. When the core is separated from the touch roller, the load on the movement drive mechanism is only a small force such as the contact pressure between the touch roller and the sheet roll in the sliding direction of the core support, and the core can swing. Compared with the winding support arm, the winding part that supports the core and separates from the touch roller does not greatly increase the occupied space, and has a vibration-proof structure against the force received from the sheet roll during winding. be able to. Therefore, even in high-speed winding, it is possible to suppress the vibration of the core and wind a high quality sheet roll. Then, the core support mechanism that winds up the sheet roll is retracted by the drive of the movement drive mechanism. On the other hand, the interlocking mechanism keeps the sheet roll unloading device below the projecting portion supporting the core of the core support while the sheet roll is being wound and during the movement of the core support mechanism to the sheet roll unloading position. The unloading device is interlocked with the core support mechanism. For this reason, the sheet roll carry-out device can immediately move upward to support the sheet roll and receive a plurality of sheet rolls released simultaneously from the respective core supports when the sheet roll reception is required. Then, the sheet roll is conveyed in the width direction of the strip-shaped sheet on the touch roller side of the core support mechanism and is conveyed out of the machine. Therefore, the work floor on the side opposite to the touch roller of the core support mechanism and the unloading of the sheet roll are irrelevant, and after the sheet roll is released, the preparatory work such as mounting the core for the next winding can be performed immediately. .

(Effects of the Invention) According to the present invention, the winding section has a vibration-proof structure to suppress the vibration of the winding core during winding, thereby effectively controlling the winding tension and the contact pressure between the touch roller and the sheet roll. This makes it possible to perform high-speed winding without causing winding defects such as unevenness of the end surface of the sheet roll. Further, since the rolled-up sheet roll is carried out in the strip-shaped sheet width direction by the sheet roll carrying-out device provided on the touch roller side of the core support mechanism, the work floor on the side opposite to the touch roller of the core support mechanism is , It is always released, and it is possible to perform the winding preparation work during the sheet roll conveyance without removing all the sheet rolls from the work floor as in the conventional method, which is efficient and at the time of unloading the sheet roll. ， No danger to workers. Further, since the sheet roll carry-out device is interlocked with the core support mechanism, it is not necessary to move the sheet roll carry-out device from the retracted position to the sheet roll receiving position when carrying out the sheet roll, and the sheet roll carry-out device can be moved to the sheet roll carry-out device. It is not necessary to provide a drive mechanism and its control device, and it is possible to support the sheet roll in a short time before releasing the sheet roll from the core support. Therefore, it is possible to significantly improve the operation rate of the sheet split winding device and increase the output of high quality sheet rolls.

The core support 3 is a projecting portion that supports the core C at its tip.
Since it has 3a, in the lower part of this protruding portion 3a,
The touch roller T side of the core support 3 can be used as a space. Therefore, a sheet roll unloading device extending in the width direction of the strip-shaped sheet is provided in this space. In the case of this embodiment, the first
As shown in the figure, the base 3c of the core support 3 projects toward the touch roller T side, and is provided in the space surrounded by the adjustment base 9 of the touch roller T, the core support 3, and the base 3c and the projection 3a. As the sheet roll unloading device, a conveyor 12 that drives the endless belt 12b by a motor 12a to convey the sheet roll in the width direction of the belt-shaped sheet is provided.

Align the left and right movable bases 13.
The movement amount of 13 is made equal.

When releasing the sheet roll R from the core support mechanism 4, the conveyor 12 must be moved directly below the sheet roll R. However, when the sheet roll R is released, the conveyor 12 is moved to the release position of the sheet roll and positioned. Therefore, preparing the drive mechanism and its control device makes the device expensive and complicated. Therefore, an interlocking mechanism that interlocks the conveyor 12 and the core support mechanism 4 is provided. In this embodiment, as shown in FIG. 6, as the interlocking mechanism, it is supported between the interval adjusting base 2 of the core support mechanism 4 and the beam 23 on the conveyor 12 side through the stoppers 29 and 30. The coil spring 31 is provided. The spacing adjusting table 2 is provided with a positioning member 32 for positioning the conveyor 12 directly below the sheet roll R on the core support mechanism on the beam 23 side.
The coil spring 31 is supported in a slightly extended state so that the conveyor 12 is pulled by 31 and the beam 23 contacts the positioning member. Therefore, the conveyor 12 has the core support mechanism 4
It can be accurately kept right below the upper sheet roll R and can move to the release position of the sheet roll R together with the core support mechanism 4. However, if the conveyor 12 is slightly displaced from the sheet roll R in the front-back direction without hindering the carry-out of the sheet roll R, the positioning member 32 may be omitted and the coil spring 31 may be supported in a loose state. In order to convey the sheet roll R released on the conveyor 12 in the sheet width direction, the projecting portion 3a of the core support 3 must be retracted from the sheet roll R. At that time, the conveyor 12 and the core It is necessary to prevent the interlocking with the support mechanism 4. Therefore, a movement blocker 33 that blocks the movement of the conveyor 12 is fixedly provided at a predetermined position on the base 5. In the case of this embodiment, the movement blocker 33 comes into contact with the end surface of the movable table 13 to block its movement. The coil spring 31 is supported by the movable base 13 and the space adjustment base 2 instead of the space adjustment base 2 and the beam 23, the lifting guide mechanism 14, the conveyor machine frame 12c, the core support 3, and other windings. This can be performed by using the member in the core support mechanism and the member in the mechanism for supporting the conveyor 12.
Further, as the interlocking mechanism, instead of the coil spring 31, an elastic body such as rubber which can be expanded and contracted, and a fluid pressure cylinder mechanism which can be expanded and contracted by a constant force by being supplied with a liquid pressure from a fluid pressure source capable of keeping the pressure constant Etc. can be adopted, and as shown in FIG. 3, the coil springs 31 can be provided not only at two positions on the left and right but also at more positions or at one position.

To wind the divided sheet S'by this sheet winding device, the winding core support mechanism 4 supporting the new winding core C is attached to the winding start position as shown in the right half of FIG. After stopping the tips on the core C by gluing,
Start and start the winding. During winding, the moving drive mechanism 7 drives the core support mechanism 4 to rotate the core C while separating the core C from the touch roller T according to the thickening of the sheet roll R. The take-up tension of the divided sheet S'is controlled through the pressing mechanism 11 through the 34.
The contact pressure between the touch roller T and the sheet roll R is controlled via. Since the winding portion has a vibration-proof structure, vibration is suppressed and the sheet roll R is wound up with good quality. When the winding of the sheet roll R is completed and the winding is stopped, the motor 7c of the movement drive mechanism 7 is started, the core support mechanism 4 is driven, and the sheet roll R is placed at the release position as shown in FIG. The conveyor 12 is raised by the lifting drive mechanism 14 to support the lower surface of the sheet roll R. In this case, the pallet 35 placed on the conveyor 12 supports the sheet roll R, but the conveyor 12 may directly support the sheet roll R. During this time, the conveyor 12 is linked to the core support mechanism 4 while being positioned directly below the sheet roll R by the action of the coil spring 31. When the sheet roll R is supported by the conveyor 12, the core attaching / detaching mechanism 3b is operated to release the core C, and the motor 7C is restarted to move the drive supporting mechanism 7 to move the core supporting mechanism 4 to the eighth position. It is retracted to the retracted position as shown. On the other hand, since the conveyor 12 is prevented from moving by the movement blocker 33, even if the core support mechanism 4 retracts, the coil spring 31 only extends and the conveyor 12 stops at the sheet roll unloading position. In this way, the protruding portion 3a of the core support 3 is retracted from the sheet roll R. As a result, the sheet roll R can be conveyed in the width direction of the belt-shaped sheet. After this, the motor 12a of the conveyor 12 is activated to convey the sheet roll R to the machine side of the sheet dividing and winding machine and carry it out to the conveyor or the like in the next process. Before starting the conveyance of the sheet roll R by the conveyor 12, it is necessary to cut each divided sheet S ′ connected from the sheet roll R to the touch roller T in the width direction by an appropriate cutting means. . Further, while the sheet roll R is being conveyed, on the side opposite to the touch roller T of the core support body 3, from the work floor 36 supported on the base 2b of the space adjusting base 2, the worker supports a new core by a core support mechanism. Prepare on 4. Sheet roll R
When the unloading of the
After driving to the lower limit, the motor 7c is rotated in the reverse direction, and the moving drive mechanism 7 drives the core support mechanism 4 to reach the winding start position. When the core support mechanism 4 advances to the winding start position, the conveyor 12 is pushed and positioned right below the core C, and moves forward together with the core support mechanism 4 to stand by. As described above, the conveyor 12 is automatically positioned at a predetermined position by the action of the coil spring 31 and the movement blocker 33, and does not require an external operation or a movement drive mechanism dedicated to the conveyor 12, and the sheet roll is automatically positioned. R can be carried out. In this embodiment, the open position of the sheet roll R of the core support mechanism 4 and the carry-out position of the sheet roll R of the conveyor 12 are the same, but the position slightly retracted from the release position of the sheet roll R is the conveyor 12. The sheet roll R may be used as the carry-out position. Further, the conveyor 12 is the core support mechanism 4
Moves up to the sheet roll release position, but rises, but since the conveyor 12 and the core support mechanism 4 work together, after the winding is completed,
The conveyor 12 may be raised while the core support mechanism 4 is retracting. The moving drive mechanism 7 and the lifting drive mechanism 1
5. The operation of the motor 12a for conveying the conveyor 12 and the like may be performed by an automatic controller or an operator. Further, although the lifting guide mechanism 14 of the conveyor 12 is provided on the movable table 13 in this embodiment, the lifting guide mechanism is provided at a fixed position to support the movable table, and the conveyor is mounted on the movable table. You may make it move in the same direction as the core support.
Further, the lifting guide mechanism, the lifting drive mechanism, the movement drive mechanism, etc. are not limited to this embodiment, but may be of other types as appropriate.

9 and 10 show a second embodiment of the present invention. FIG. 9 is a side view of the winding unit at the winding position on one side, and FIG. 10 is a front view partially showing the winding unit and the sheet roll carry-out device. FIG. 9 shows a cross section taken along the section plane AA of FIG. The parts having the same functions as those in the first embodiment will be described with the same reference numerals as those in the first embodiment.

This embodiment differs from the above-described first embodiment in that an engaging mechanism 37 for detachably engaging the conveyor 12 and the core support mechanism 4 is provided as an interlocking mechanism. Engagement mechanism 37
In this case, the engaging rod 39, which is loosely fitted in the guide cylinder 38 fixed to the space adjusting base 2 and can be moved up and down, and has the engaging portion 39a having a small diameter at the lower end, and the conveyor 12 are located directly below the sheet roll R. When coming, the engaging portion 39a of the engaging rod 39 is received, the engaging hole 40 provided in the movable base 13, the follower 42 supported at the lower end of the bracket 41 attached to the lower side surface of the engaging rod 39, and the conveyor 12 Is moved to the sheet roll R carry-out position, the follower 42

With 43. The engagement rod 39 is prevented from rotating by a key or the like. When the core support mechanism 4 is retracted from the unloading position of the sheet roll R of the conveyor 12, the engagement rod 39 is pushed up by the cam 43 and is in the disengaged state, but the core supporting the new core is supported. When the support mechanism 4 moves forward to the winding start position, the engaging rod 39 is released from the cam 43 and loses the pushing-up force.
Is a conveyor stopped at the unloading position of the sheet roll R
It falls into the engaging hole 40 on the movable base 13 of 12 and becomes an engaged state,
The conveyor 12 and the core support mechanism 4 work together. The engaging part
The engagement portion 39 can surely drop into the engagement hole 40 by tapering the tip of the 39 or by making the engagement hole 40 a long hole in the front-rear movement direction. In addition, the engagement mechanism uses the cam as described above.
Instead of performing engagement / disengagement operation by 43, another sensor detects the carry-out position of the sheet roll R of the conveyor 12, and based on this detection signal, a drive mechanism such as a fluid pressure cylinder that receives a drive command from the control device. It is also possible to engage and disengage the engaging rod 39 by. In addition, instead of inserting the engaging portion into the engaging hole, the engaging mechanism adopts, for example, a pawl as the engaging portion and disengages via the pawl, or an engaging rod provided in the horizontal direction. Grab the outer periphery of the with a clamp member driven by a drive mechanism, and engage with the friction force,
Alternatively, the tip of the swing lever may be formed as an engaging portion, and the present invention is not limited to the above embodiment. Also,
A control mechanism, a clamp mechanism, or the like may be provided to surely stop the movable table 13 at the unloading position of the sheet roll R.

FIG. 11 and FIG. 12 show a third embodiment of the present invention. FIG. 11 is a side view of the winding unit at the winding position on one side, and FIG. 12 is a front view of the winding unit and the sheet roll unloading device. In addition, the portion that performs the same operation as in the first embodiment,
The same reference numerals as in the first embodiment will be used for description.

In this embodiment, the interlocking mechanism is mainly provided with a base 44 supported by the core supporting mechanism for supporting the entire sheet roll unloading device instead of the coil spring.
Different from the embodiment. In the case of this embodiment, the base 44 is horizontally fixed to the lower portions of both ends of the space adjusting base 2 and protrudes to the left and right from both ends of the space adjusting base 2. Then, on the base 44, a movable base for supporting the rail 16a, the movable body 16b and the conveyor 12 is provided as in the first embodiment. And
The movable base 13 has a locking portion 45 protruding outward from the base 44, and a movement blocking body 33 that engages with the engagement portion 45 on the base 5 and blocks the movement of the movable base 13. Is fixed. The lifting guide mechanism 14 is designed in consideration of the lifting amount of the conveyor 12. Since the conveyor 12 is mounted on the base 44 fixed to the interval adjusting base 2 of the core support mechanism 4, the movable base is movable at the sheet roll R unloading position in the same manner as in the first embodiment.
Until the engaging portion 45 of 13 engages with the movement preventing body 33 and the movement of the movement preventing body 33 is prevented, it is interlocked with the core support mechanism 4. From the unloading position of the sheet roll R, only the core support mechanism can be retracted, and the protruding portion 3a of the core support 3 can be retracted from the sheet roll R delivered on the conveyor 12. When the core support mechanism 4 moves forward to the winding start position, the conveyor 12 is in a state of being positioned directly below the core C, and the positioning member 32 causes the beam 23 to move.
Is pressed to move forward together with the core support mechanism to move the sheet roll R
Both retract to the carry-out position. A coil spring or the like may be used between the conveyor 12 and the core support of this embodiment as in the first embodiment. The base 44 may be attached at a position other than the lower portion of the space adjusting base 2, or a rail or the like may be fixed to the core support mechanism and used as the base. In this embodiment, since the sheet roll unloading device is placed on the base supported by the core support mechanism and the two are interlocked, the structure is simple.

A fourth embodiment of the present invention will be described with reference to FIG. First
FIG. 13 is a side view of the winding unit and the sheet roll unloading device. The parts having the same functions as those of the above-described third embodiment will be described with the same reference numerals as those of the third embodiment. In this example,
The base 44 is fixed to the space adjusting base 2 by projecting it to the touch roller side, and the elevator guide mechanism 14 that supports the conveyor 12 using the link mechanism so that the conveyor 12 can be horizontally moved up and down is driven on the base 2c. And a well-known lifting drive mechanism 15 composed of a fluid pressure cylinder for raising and lowering the conveyer 12 by means of the core support 3
Is formed in a C shape, the lifting guide mechanism 14 is supported on the base 44 so as to be movable back and forth without passing through the movable base 13 as in the third embodiment, and the sheet roll R is unloaded. At the position, the elevating drive mechanism 15 drives the elevating guide mechanism 14 to lower the conveyor 12 to retract the sheet roll R on the conveyor 12 from the core support 3, and then convey the sheet roll R by the conveyor 12. This is different from the third embodiment described above in that it is not necessary to further retract the core support mechanism 4 from the sheet unloading position of the sheet roll R. It should be noted that the base of the gap adjusting base 2 mounted on the sliding mechanism as the base 44
2b can be used, and the mounting position of the base 44, the lifting guide mechanism, the lifting drive mechanism, etc. are not limited to those in this embodiment. In this embodiment, it is not necessary to retract the core support from the sheet roll to retract it, and the floor area of the winding section can be saved. Moreover, since it is not necessary to support the conveyor by the movable table, the structure is simplified.

Although some embodiments have been described above, it is needless to say that the invention can be variously changed and applied according to design conditions according to design conditions without changing the gist thereof.

For example, the sheet split winding machine guides the strip-shaped sheet from the sheet traveling path below the winding position to the slitter and then sorts it to the winding position. Surface drive by the touch roller or surface drive by the touch roller A winding drive system such as a composite drive by commonly using the center drive of the winding core by a drive mechanism, a type that is common to the sheet rolls at the winding positions on both sides or one side, and has a touch roller supported at a fixed position. This invention can be applied. The core support may have any shape as long as it has a protruding portion to the touch roller side in order to provide a space for positioning the conveyor below. In addition, the core attaching / detaching mechanism is of a type in which a support inserted into the hollow portion of the core end is advanced or retracted in the core direction from the core support, or the outer peripheral surface of the winding shaft supported by penetrating the core tube is clamped. It is possible to adopt a form of holding the same. Further, the core support is slidably supported laterally at right angles to the width direction of the strip-shaped sheet on its base, and a pressing mechanism for pressing the core against the touch roller supported at a fixed position is provided on the base. It may be provided. The sliding mechanism may be one in which the movable body is supported in a linear motion between the rail and the rail through rolling elements, or one in which the rail and the movable body are in direct contact with each other and slide. It may be fixed and provided so that the rail can move. The movement drive mechanism uses a fluid pressure cylinder instead of the screw shaft mechanism to directly drive the core support mechanism, or uses a rack or pinion to change the rotation of the motor into a linear motion, or a single motor. It is not limited to the above-mentioned embodiments, such as the drive by The conveyance of the sheet roll is not limited to the belt conveyor, and may be another conveyor such as a slat conveyor. Instead of these conveyors, the threaded shaft, which is movably supported on a guide beam provided in the width direction of the belt-shaped sheet and is rotationally driven in both forward and reverse directions, can be engaged and disengaged via an engaging and disengaging mechanism. Accordingly, it is possible to employ a transport mechanism having a plurality of transport stands that are moved to and positioned at desired positions, or the like, which has a function of supporting the lower surface of the sheet roll and transporting in the width direction of the strip-shaped sheet. Further, the conveyor may be supported by the side surface of the machine frame so as to project laterally from the lifting guide mechanism, or the conveyor may be supported by three or more places by the lifting guide mechanism.
