Description

Description: TECHNICAL FIELD The present invention relates to a winding device that divides a strip-shaped sheet into a plurality of strips and winds the strip-shaped sheet.

(Prior Art) The width of a strip-shaped sheet produced by a sheet-making machine tends to be wide in recent years, and in order to divide a wide strip-shaped sheet into a practical width, the strip-shaped sheet is divided by a winding device. The winding process has to be repeated many times. And, it is desirable to reduce the number of times to go through this division winding process as much as possible. Therefore, one division winding device for the strip-shaped sheet satisfies a wide range of winding width specifications from narrow width to wide width. Is required.

However, in the case of a split winder of the type in which the strip-shaped sheets divided by the winding mechanism adjacent to each other in the sheet width direction at the winding position are separately distributed and wound, the number of divisions of the strip-shaped sheets is increased,
In order to be able to wind a strip-shaped sheet that is as narrow as possible, it is necessary to make the winding mechanism as narrow as possible so that neighboring members do not interfere with each other. On the contrary, in order to reduce the number of divisions and to enable the winding of a strip-shaped sheet that is as wide as possible, that is, in order to increase the maximum winding width specification, the winding mechanism is a core drive mechanism. Depending on the situation, it is necessary to make the core support and the like larger. In that case, the winding mechanism becomes large in the width direction, so that the winding of a narrow width becomes impossible. Therefore, a split winding device including a plurality of winding mechanisms having the same winding width specification cannot satisfy a wide range of winding width specifications.

Therefore, conventionally, multiple types of winding mechanisms with different winding width specifications have been prepared, and with the change of the division width specification of the strip-shaped sheet,
Unnecessary take-up mechanism is removed from the base provided along the take-up position of the take-up device, and the take-up mechanism with the required take-up width specifications is attached to the required position on the base of the take-up device. It was

That is, the conventional split winding device equipped with a winding mechanism having different winding width specifications has a base provided along the winding position and is detachable from the base in order to cope with a change in the strip-shaped sheet split specification. Each winding mechanism was simply equipped with a fixing mechanism such as a possible clamping mechanism.

(Problems to be Solved by the Present Invention) However, in the conventional strip-shaped sheet winding device as described above, when the strip-shaped sheet split specification is changed and the winding width specification of the winding mechanism becomes unsuitable, Each time, the winding mechanism must be removed from the base and attached to the base. Generally, the weight of the winding mechanism is large, it is difficult to move it manually, and a carrier such as a hoist must be used, and the core support of the winding mechanism is arm-shaped and unstable. The replacement work of the winding mechanism requires many workers, a long working time, and is dangerous.

It also requires a place to store the unstable winding mechanism removed from the base in a stable state. Furthermore, winding torque,
It is necessary to disconnect or connect the electric wire, the pneumatic hose, etc. for controlling the contact pressure between the touch roller and the winding sheet roll each time the winding mechanism is replaced.

(Means for Solving the Problems) Therefore, according to the present invention, a strip-shaped sheet is divided into a plurality of strips by a slitter, and the divided strip-shaped sheets are distributed to a plurality of winding positions and are supported at the respective winding positions. In a winding device that winds around a winding core that is individually and rotationally driven so that the torque can be adjusted, a guide base provided in the strip sheet width direction along the winding position, and a guide base guided by the guide base. At least one of which supports the core by a pair of core supports that are movably mounted, and rotationally drives the core by a core drive mechanism provided on both or one of the core supports. Are a plurality of winding mechanisms with different winding width specifications, a screw shaft that is provided along the guide base and is driven to rotate in both forward and reverse directions, and a screw shaft that is attached to and detached from the screw shaft provided on the core support. Possible engagement and disengagement mechanism and along the above guide base A flexible wire and / or a hose for supplying electricity or pressure fluid to each core support, and supporting means for supporting the flexible wire and / or the hose so that the bending radius is maintained at an allowable value or more. And

(Operation) At least one supports a plurality of take-up mechanisms including a take-up mechanism with different take-up width specifications in common on a guide base, and guides them at the same time. By disengaging the winding core support of the winding mechanism from the screw shaft by the engaging / disengaging mechanism, the winding mechanism having the required winding width specification can be moved to the required position of the guide base, and the winding base can be moved from wide to narrow. It is possible to cope with changes in the winding width up to the width.

(Embodiment) FIGS. 1 and 2 show a first embodiment of the present invention.
FIG. 1 is a plan view of a strip-shaped sheet winding device,
The figure is an explanatory view of the same side. Further, FIG. 3 is an illustration of an embodiment of the engagement / disengagement mechanism. And the original roll (not shown)
The strip-shaped sheet S unwound from the strip-shaped sheet S is divided into a plurality of strips by the slitter blade K into strip-shaped sheets S ′ _{1 to} S ′ ₄ having a narrow width. The sheet rolls R are distributed and wound around the tubular or axial winding core C to form the sheet roll R.

Above, Along the left and right take-up position, the guide and the base 1 is provided to be fixed on the frame F in the sheet width direction, divided winding of the belt-like sheet S _'1 to S' ₄ of six Mechanism RW
₁ , RW ₂ , RW ₃ and RW ₄ , RW ₅ , RW ₆ are arranged on the left and right guide bases 1. A screw shaft 2 is provided along the guide base 1, and the screw shaft 2 can be rotated normally and reversely by driving a drive mechanism M1.

The winding mechanisms RW _{1 to} RW ₆ mainly support a pair of winding cores 3 that are supported and guided by the guide base 1 to support and drive the band core C, respectively, and are movable in the seat width direction. , And a core drive mechanism 4 which is attached to the core support 3 and rotationally drives the core C with a required torque. In this embodiment, the core support 3 is slidably mounted on the guide base 1 and an arm 3a having a support shaft 3c that removably supports the core C at one end. The screw shaft 2 is penetrated and the screw shaft 2
It is composed of a base portion 3b having an engaging / disengaging mechanism 5 that can be engaged and disengaged with. In this embodiment, the engagement / disengagement mechanism 5 is, as shown in FIG. 3, screwed onto the screw shaft 2 and supported by a bearing member 5a fixed to the base 3b for bearing the screw shaft 2.
Nut 5b and base 3b are constrained to move axially with respect to
It is composed of a piston 5c, which is fixed to the piston 5c, and a fluid pressure cylinder 5f which pushes out a rod 5e having a friction member 5d attached to the tip thereof against a compression coil spring 5g by a pressure fluid supplied from the outside. When moving the core support 3, the screw shaft 2 is rotationally driven and the fluid pressure cylinder 5f
When a pressure fluid is supplied to the surface of the nut 5b and the friction member 5d is frictionally engaged with the surface of the nut 5b, the rotation of the nut 5b is restricted, the screw shaft 2 and the nut 5b rotate relatively, and the nut 5b and the base 3b together. Also moves on the guidance base. Fluid pressure cylinder
When the supply of pressure fluid to 5f is stopped, the compression coil spring 5g
By this action, the rod 5e is retracted, the friction member 5d is separated from the nut 5b, the nut 5b can rotate together with the screw shaft 2, and the core support 3 and the screw shaft 2 are disengaged. As a result, the core support 3 stops moving. The arm portion 3a of the core support is swingably supported by the base portion 3b of the swing support shaft 3d, and during winding, the arm portion 3a of the core support supports the winding of the sheet roll R. According to the increase in weight, the core C is swung to separate the winding core C from the touch roller.

A fluid pressure cylinder for swinging the arm 3a between the base 3b of the core support and the arm 3a and adjusting the contact pressure between the sheet roll R and the touch roller T during winding. 6
(The drawing is omitted in FIG. 1).

Of winding mechanism RW ₁ to _{RW 6, RW 1, RW 3} , RW 4, RW 6 , the winding Tohaba specification are respectively the same, RW ₂ and RW ₅ is also the winding width specifications are the same However, the take-up width specifications of RW ₂ and RW ₅ are different from the take-up width specifications of other take-up mechanisms, and are larger than the others. That is, the winding mechanisms RW ₂ and RW ₅ are capable of winding a divided strip-shaped sheet having a wider width than other winding mechanisms. Therefore, other winding mechanisms RW ₁ , RW
_The core drive mechanism 4 for rotating and driving the core C is attached only to one side of the pair of left and right core supports _{3 to 3} , RW ₄ and RW ₆ , but the winding mechanisms RW ₂ and RW ₅ A core drive mechanism 4 is attached to both sides of the pair of left and right core supports. In this way, when two winding core drive mechanisms are provided in one winding mechanism and are driven in parallel, the winding width is about twice as large as that when only one winding core drive mechanism is provided and driven. Winding is possible. Since the core driving mechanisms are attached to the core supporting bodies 3 one by one, only one side of the pair of core supporting bodies 3 is provided.
The weight of the left and right core supports is better balanced and the swinging force of the arm 3a due to the reaction of the core driving force can be equalized compared to the case where the core driving mechanism with double the output is mounted. The parallelism between C and the touch roller T can be easily maintained accurately, the adverse effect on the control of the contact pressure between the touch roller T and the sheet roll R is small, and a large balance weight is not required for the core support. Even for a winding mechanism with a large maximum winding width specification, the width of the winding mechanism can be reduced as a whole, and the minimum winding width specification can be reduced. Also, since the driving force is distributed to the winding core C and transmitted to both sides,
Even when the core C is supported by inserting the support shaft 3c that is movable in the axial direction of the core only into both ends of the core, the end of the core has a torque half the winding torque. Since it only acts, the end portion of the winding core is not easily damaged and the driving force can be reliably transmitted to the winding core. Further, when winding a strip-shaped sheet having a narrow width, only one of the two core drive mechanisms 4 can be used for winding. The core drive mechanism 4 uses an inverter in this embodiment to speed-
An induction motor for torque control is used, and the driving force is transmitted from the output shaft of the induction motor to the winding core C to which the support shaft 3c is attached via a transmission mechanism. However, instead of the induction motor, a DC motor, a hydraulic motor or the like may be used.

Since the core drive mechanism 4, the engagement / disengagement mechanism 5, the fluid pressure cylinder 6 and the like are attached to the core support 3 which is movable on the guide base 1, they move together with the core support, so that they are electrically connected. Equipped with a flexible electric wire and hose support frame 7a that supports a flexible electric wire or hose (not shown) for supplying pressure fluid and pressure fluid while maintaining the bending radius of the hose above an allowable value. An electric wire / hose supporting means 7 is provided below the work floor along the guide base. The electric wire hose and the supporting means 7 of this embodiment are, for example, as disclosed in Japanese Utility Model Laid-Open No. Sho 60-19545, the electric wire and hose supporting frame 7a have one end and the other end wound on the guide base 1. Each arm that is fixed or engaged with the core support 3 and moves together to move along the guide base 1, and a common support material provided below the arms and along the guide base. Fixed to or engaged with, and bent back in the middle to form a curved portion.
7a is attached so that it bends in each space and does not interfere with each other. In addition to the illustrated core support, a drive mechanism for advancing / retracting the support shaft 3c to the core C end, a core preparation device, a clamp mechanism for a connecting rod between a pair of core supports, a winding, When the core support moves to a predetermined position, a lock mechanism for locking the core support to the guide base is attached, and it is necessary to supply electricity and pressure fluid to them as well, but detailed description thereof will be omitted. Both the flexible electric wire and the hose may be housed in one supporting frame 7a or may be separated. In addition, the allowable value of the bending radius of the flexible wire or hose may be selected by the designer in consideration of the life of the wire or hose without causing any trouble.

In this embodiment, division retractor, the maximum winding Tohaba use of large winding mechanism RW _2, RW ₅ and the maximum winding Tohaba specification small winding mechanism _{RW 1, RW 3, RW 4} , RW 6 , Since they are movably provided on the guide bases 1 provided at the front and rear winding positions respectively, the guide base 1 can be moved to a required position without attaching or detaching the winding mechanism to or from the guide base. The strip-shaped sheet can be divided into 2 to 6 strips and wound as a sheet roll. In FIG. 1, the strip-shaped sheet S is divided into six strips, but the strip-shaped sheets divided at both ends are treated as cutting waste, and the remaining four strip-shaped strips S ′ _{1 to} S ′ ₄ are the sheets. It is wound up as a roll. Divided belt-like sheet S _'2, S' ₃
Since the dividing width is wide, the winding mechanism is
RW ₅ and RW ₂ are respectively arranged, and the winding mechanism R is provided at the winding position of the strip-shaped sheets S ′ ₁ and S ′ ₄ which are divided into narrow strips.
W ₁ and RW ₆ are arranged respectively. The winding mechanisms RW ₃ and RW _{4 that} are not used for winding are arranged at the standby position on the guide base 1 that does not hinder the winding operation. If it is necessary to change the winding specifications according to the change in the division specifications such as the division width and the number of divisions of the belt-shaped sheet, the winding width specifications conforming to the division width of the belt-shaped sheet are taken up. The mechanism may be arranged at the winding position or the standby position of each divided strip sheet to change the winding specification. Arrangement of each winding mechanism at a required winding position or standby position is performed by disposing the respective engaging / disengaging mechanisms 5 on the screw shaft 2 which is normally or reversely driven as described above. By engaging and disengaging the core support members so that the core support member spacing of the pair of core support members becomes a required interval, and the core support member is placed at a position for supporting the core member corresponding to the division position of the strip-shaped sheet. This is done by moving. For example, when the strip-shaped sheet is divided into halves, since the division width is large, RW ₂ and RW ₅ are used as the winding mechanism and the other winding mechanisms are put on standby. When dividing into 6 strips, use the entire winding mechanism. The winding mechanisms RW ₂ and RW ₅ have a large maximum winding width specification, but since the winding core drive mechanism is separately installed on both the pair of left and right winding core supports, the minimum winding width specifications can be changed to other winding winding specifications. The value can be made close to the minimum winding width specification of the take-up mechanism, or can be reduced to the same degree. The number of winding mechanisms, the winding width specification, the arrangement of the winding mechanisms, etc. are not limited to those in this embodiment, and can be variously designed as necessary.

4 to 5 show a second embodiment of the present invention, and FIG. 4 is a plan explanatory view of a strip-shaped sheet winding device, FIG.
The figure is an explanatory view of the same side.

The strip-shaped sheet winding device of this embodiment swings around one end on a support base 11 which is provided in the middle of the front and rear winding positions in the sheet width direction and which is supported by a guide beam 10 and is movable by being guided. A touch roller T is individually attached to each of the winding mechanisms at the other ends of the pair of swingable arms 12 that are supported so that the contact pressure between the sheet roll R and the touch roller T during the winding is set to the support base 11. Pushing drive mechanism (fluid pressure cylinder) provided between the swing arms 12.
The core support 3 of the winding mechanism has a structure in which the arm 3a is fixed to the base 3b, and the base 3b of the core support 3 is slid. The guide base 1 which is movably supported and guided is rotatably supported at both ends thereof about an axis parallel to the axis of the winding core C, and drives an arm 14 fixed to the guide base 1. It rotates by pushing and pulling by the mechanism (fluid pressure cylinder) 15. Therefore, each core support 3 can also rotate together with the guide base 1, and the sheet roll R becomes thick during winding. Then, the core C supported by the tip of the core support 3 is continuously or intermittently driven by the drive mechanism (fluid pressure cylinder) 15 to keep the position of the touch roller T substantially constant. Separate from the touch roller T, the electric wire, the arm 8 of the hose supporting device 7, and the core support 3, the winding core support can keep the engagement be rotated about the axis of the guide base 1 is mainly different from the split winding device of the belt-like sheet of the first embodiment described above. In addition, in FIG. 4, the strip sheet S is shown.
3 is disassembled into three parts and wound up. In this case, since the winding core C of the sheet roll R of the winding mechanism has a large winding width, it shows a state in which a size larger than the others is used. .

6 and 7 show a third embodiment of the present invention. FIG. 6 is a plan view of a strip-shaped sheet winding device and FIG. 7 is a side view of the same.

The strip-shaped sheet winding device of this embodiment uses a slip clutch (for example, a magnetic powder clutch) as the core driving mechanism 4 for rotationally driving the core C so that the torque can be adjusted, and three different types. It is mainly equipped with the winding mechanism with the winding width specification, and the winding mechanism with the maximum winding width specification is arranged at the most diagonal position on the front and rear guide bases. Different from the strip-shaped sheet winding device in the example. And
An input shaft of each slip clutch used as the core drive mechanism 4 is provided with a line shaft 16 provided along the guide base 1 and a transmission mechanism (gear train) 17 that can move together with the core support 3. The power of the motor M ₂ is transmitted. still,
In this embodiment, since the arm portion 3a of the core support needs to swing with respect to the base portion 3b, one of the four gears, which is a transmission mechanism, is supported coaxially with the swing support shaft 3d. Has been done.
Further, the output shaft of the slip clutch in this case is of a type that is provided on the same side as the input shaft and penetrates the input shaft and projects from the input shaft end.

The winding mechanisms RW ₃ and RW ₄ have the slip clutch attached to only one of the pair of core supports, and have the same winding width specifications.
The winding mechanisms RW ₂ and RW ₅ have slip clutches of the same capacity as the above RW ₃ and RW ₄ mounted on both of the pair of core support members, and have the same winding width specifications. The winding mechanisms RW ₁ and RW ₆ have a slip clutch of a larger capacity than the slip clutch of the above-described winding mechanism mounted on both of the pair of core supports, and have the largest maximum winding width specification. Therefore, this winding mechanism
RW ₁ and RW ₆ have a large width in the width direction of the strip-shaped sheets, but they are arranged at the end and interfere with the adjacent winding mechanism by the pair of core supports and the core drive mechanism. Since only one of them is used, it is possible to eliminate the influence on the winding width of the other winding mechanism. Even though the core support interval is large by itself, even a strip-shaped sheet divided into narrow widths is wound up. be able to. In FIG. 6, the winding mechanism RW ₁ supports the winding core C longer than the division width of the strip-shaped sheet between the support shafts 3c.
By mounting the adapter on the support shaft 3c, it is also possible to wind using a winding core having the same length as the division width of the strip-shaped sheet.

The present invention has been described above with reference to a few examples, but it goes without saying that the modes in its implementation can be variously changed and applied by well-known techniques of designers and the like.

For example, the engagement / disengagement mechanism of the core support. Not limited to the one shown in FIG. 3, a nut engaged with a screw shaft is engaged with the core support by using an electromagnetic clutch, or a half nut is directly engaged with the screw shaft. The thing etc. can be used.

The winding core support of the winding mechanism may approach or separate from the touch roller in a linear approach or away form, or in a form in which the touch roller separates from the core support, instead of the turning motion type as shown. Good. The core support may be movably supported between the core support and the guide base via rolling elements.

The core drive mechanism of each winding mechanism may be attached to only one of the pair of core supports, or the core drive mechanisms of different capacities may be attached to the left and right core supports. Further, the electric wire and hose supporting means are not limited to the type using a flexible supporting frame, but may be the type supporting the electric wire or hose in a spiral shape with a pulley hung on a rail or a messenger wire. . Further, the position where the electric wire supporting means is provided is not limited to the illustrated position as long as it is along the guide base and the stand. In the above-described embodiment, the split winding device is provided with the slitter below the winding position as shown in the drawing, but the present invention is also applicable to the type in which the strip sheet traveling path and the slitter are provided above the winding position. It is also possible to apply the invention.

(Effect of the Invention) According to the present invention, a plurality of winding mechanisms having different winding width specifications are provided on a common guide base so as to be movable, and when the strip-shaped sheet division width specifications are changed, the screw shaft Drives the winding mechanism with a winding width specification that matches the strip sheet division width to the required winding position for the divided strip sheets, and the winding width and the number of windings of the strip sheet split winding device. Since the winding specification such as is changed, the winding mechanism provided on the guide base can be used for a wide range from narrow width to wide width without removing the winding mechanism from the base or attaching it to the base. It is possible to wind a strip-shaped sheet with a divided width, and it is possible to move multiple winding mechanisms at the same time, so that the winding specifications can be changed accurately in a short time. In addition, the work of changing the winding specification requires almost no labor and no danger is involved.
