Description

[Detailed Description of the Invention] <Industrial Application Field> This invention divides a wide belt-like sheet into a plurality of narrow sheets and distributes them alternately to the left and right, and the narrow sheets are distributed to the right side and left side. A slitter winder that winds the sheet as a narrow sheet roll on a core that is supported by a core support that is movable individually in the width direction of the strip-shaped sheet and that is rotationally driven with a required winding torque. This invention relates to a method for winding up a belt-shaped sheet in a machine.

<Prior art> In this type of slitter winding machine, in order to be able to support cores of various lengths, each pair of core supports is made movable in the width direction of the strip sheet. The support is provided with opposing supports, and the support is inserted into and supported by the winding core, and the winding core and the winding core support are extrapolated onto the winding shaft so as to be movable in the axial direction. There is a method in which the shaft is attached to the core support after inserting and fixing supports into both ends of the core.

Conventionally, only one core was supported by the above-mentioned pair of core supports, and one divided narrow sheet was always directed toward one core, and this was wound onto a total 418 m sheet roll. A method of raising was adopted. In other words, the narrow sheet, the winding core, and the pair of core supports were always wound in a 1:1 relationship.

<Problem to be solved by the invention> A slinter winding machine is required to meet the demands for diversification of dividing specifications by winding up narrow sheet rolls with various dividing widths simultaneously with a single device. .

However, although it is not limited to this type, the core support of the slitter winder has a mechanism for directly or indirectly driving the core, or in some cases uses power in the width direction of the strip sheet. Because a moving mechanism and the like are provided, the core support itself also has a certain width. Therefore, when the relationship between the divided narrow sheet and the core and a pair of core supports is 1:1 as in the past, the narrow sheet roll is narrower than the approach limit width between adjacent core supports. It cannot be rolled up and cannot meet requests for diversification of division specifications.

In other words, this type of slitter winding machine alternately distributes divided narrow sheets to the left and right or up and down, so it is possible to wind up a sheet roll having a width narrower than the approach limit width using the winding core support on one side. Then, the core supports for winding the narrow sheet adjacent to the sheet and distributed to the other side collide with each other.

Conventionally, when it is necessary to wind up a sheet roll whose width is narrower than the approach limit width between the core supports, the sheet roll is first wound to the width that can be wound, and then the narrow sheet is divided and wound. A dedicated slitter winding machine was used to wind up the sheet into rolls of the required width, but this required two steps, which wasted time.
It is clear that problems such as deterioration of work efficiency and, in some cases, waste of sheets occur. Furthermore, even if it is obvious that there is a narrow continuous defective part in the belt-shaped sheet, it is necessary to wind up a wasteful sheet roll with a considerable width including the defective part. The dedicated slitter winding machine is of the type that - one after another, winding cores of the required width are extrapolated onto a wooden winding shaft and are wound into sheet rolls, and the winding shaft is removed after winding. Therefore, if the winding shaft is made too long, the winding torque cannot be applied equally to each winding core, making it impossible to wind a wide belt-shaped sheet or wind up many sheet rolls at the same time. - Winding a large number of sheet rolls around a wooden shaft means:
It is also troublesome to remove the winding shaft after winding and to carry out the sheet roll. That is, although a slitter winding machine dedicated to narrow-width winding is excellent in winding up narrow-width sheets, it is still impossible to deal with various division specifications using this machine alone.

In addition, in the past, even when one strip-shaped sheet was divided into an extremely large number of strips, a number of core supports were prepared corresponding to the number of narrow sheets; The work of moving and positioning the core support when the winding speed changes is extremely troublesome and takes a lot of time, resulting in a deterioration of work efficiency.

Therefore, the present invention divides a wide belt-like sheet into a plurality of narrow sheets and distributes them alternately to the left and right or top and bottom, and distributes the narrow sheets to the right side and the left side. A slitter winder that winds the strip sheet as a narrow sheet roll on a core that is supported by respective core supports that are movable from side to side in the width direction of the strip sheet and that is rotationally driven with a required winding torque. In the machine, at least one of the winding core supports supports a winding shaft passing through the winding core, and each of the winding shafts is capable of winding up a narrow sheet roll on a tool through the winding core. It is characterized by

Function> In the present invention, a core or a winding shaft is supported by a single core support, and in this case, the winding shaft simultaneously winds up a plurality of divided narrow sheet rolls through the respective winding cores. Therefore, when winding a narrow sheet narrower than the approach limit width of the winding core support, multiple narrow sheets adjacent to the narrow sheet and distributed to the other side are A winding core having a width corresponding to the width is extrapolated onto a single winding shaft supported by a single core support and wound. Further, when the number of narrow sheets varies over a wide range, a plurality of winding shafts each wind a plurality of narrow sheets.

Embodiment FIGS. 1 and 2 show a first embodiment of the present invention, in which FIG. 1 shows a side view of a slitter winder, and FIG. 2 shows a plane view of a sheet roll being wound up.

The slitter winder itself is of a conventional type, that is, a strip sheet S passed through various guide rollers is divided into multiple narrow sheets by a slitter blade K, and then passed through a touch roller T and rolled onto a core C. It is wound up as a sheet roll R. Then, the winding core C is distributed to the right side and to the left side, respectively, on the respective winding core supports A and A', which are movable on the sliding guide base 2 provided in the width direction of the strip sheet S. A press-type support 1 rotatably attached to the tip of the handle 3
0, and each is rotationally driven with a required winding torque by a drive mechanism (not shown). Or, it indicates the width of each core support A, A', where Sa is a narrow sheet larger than the value of x+x, that is, wider than the approach limit width between the core supports, and R is the width of the core support. It is a rolled up sheet roll. Note that it is theoretically possible to wind up even if the value of the above narrow sheet (Sa) is the same as the value of Since the core supports of the narrow sheet Sa are in contact with each other,
The value of is preferably larger than the value of x+x. Sa' is a narrow sheet narrower than the value of x+x, and Ra is the rolled sheet roll. The sheet rolls in the case of Fig. 2 are R, R, R,
It is wound up in the order of R, R1Ra, and Ra. In the conventional winding method, the relationship between the narrow sheet and the winding core was always one-to-one, so it was impossible to wind the narrow sheet Sa'. For example, two cores C are inserted and fixed onto a core L supported by push-type supports LO of a pair of core supports A and A' on the rightmost side in the drawing, and a sheet roll R, In the same way, two cores are inserted and fixed onto the rightmost roll shaft l on the rear side to wind up the sheet rolls Ra and Ra, so even if the sheet is a narrow sheet Sa', It can be wound up as a sheet roll Ra. In this case, two sheet rolls (R and Ra
, Ra and Ra) is a shaft-shaped winding shaft supported by a press-type support lO of the pair of winding core supports A and A'. In order to support the two winding cores C, a known roller lock mechanism for fixing the inner periphery of the first winding core C, a blade in the radial direction, etc. are provided. Therefore, the winding core C will not shift during sheet winding. On the other hand, a core C for winding one sheet roll R with a pair of core supports A and A' is a shaft-shaped winding shaft equipped with a core fixing mechanism as described above, and is attached to a push-pull type support 10. However, in order to accurately deal with various division widths, it is necessary to directly support the winding core C with a press-type support lO installed between the pair of core supports and facing each other. It is preferable to make it possible to clamp it, and in that case, in order to make it possible to attach both the shaft-shaped winding shaft l and the winding core C,
It is preferable to make the above-mentioned supports 1O compatible.Even if they are not compatible, the operator should take into consideration the narrow width seams at the stage of determining the division position of the strip sheet. If you always direct the windings in the same direction, this can be done to some extent.

3 and 4 show a second embodiment of the invention. FIG. 3 shows a slitter winding system in which the touch roller, which was common to the right and left sides in the first embodiment, is changed to a small-diameter touch roller T' provided for each sheet roll or according to the sheet roll. FIG. 4 is a side view of the machine and a plan view of this type of slitter winding machine in a state in which a narrow sheet is wound.Each touch roller T' is supported by a support frame 17 at its bearings at both ends. , are in contact with the surface of the sheet roll, and are individually driven to rotate by a drive mechanism (not shown). The support frame 17 is slidably movable on a sliding base 18. As is clear from Fig. 4, in this case, there is a narrow sheet roll Ra), so the narrow sheet roll Ra is adjacent to the narrow sheet Sa' and distributed to the other side. The sheet rolls R1 and R2 are wound onto respective cores C which are extrapolated onto a common winding shaft 1a.

The winding shaft 1a for winding up the narrow sheet rolls Ra, R1, and R2 is constructed by extrapolating a group of narrow collars onto the drive shaft.
The drive of this drive shaft is transmitted to the winding core C via the collar. It uses a so-called friction type winding shaft. Details regarding this friction type winding shaft will be described later.

In addition, in this embodiment, narrow sheet rolls R1, R2
A common touch roller T' is brought into contact with the touch rollers T', but it is also possible to contact each touch roller T' individually.
is supported at a fixed position by a support frame during sheet winding. For example, the touch roller may be supported by the tip of a swinging arm or a sliding body provided on the support frame, and the touch roller may be moved between the support frame and the swinging arm, etc. If the pressing force of the touch rollers against the surface of the sheet rolls is individually controlled via a fluid pressure cylinder or the like, even if there is a difference in diameter between the sheet rolls due to uneven thickness of the belt-shaped sheet, etc. It becomes possible to handle each item individually and wind it with good quality.

5 to 7 show an embodiment of the friction type winding shaft 1a used in the second embodiment.

As described above, this winding shaft 1a has a plurality of narrow collars 4 equipped with winding core fixing means 18 on the outer periphery inserted onto the hollow drive shaft 5, and the drive of the hollow drive shaft 5 is controlled via the collars 4 to the winding core. It is a type of winding shaft that transmits information to the winding shaft, and the winding torque near the ends and center of the winding shaft is almost the same, and the winding torque is almost proportional to the number of collars. It is particularly suitable for winding up multiple sheet rolls with different widths on the winding shaft. In FIG. 5, the common drive shaft 6 provided along the guide base 2 is driven by the core support A.
It is then transmitted to the hollow drive shaft 5 via the powder clutch 8 of the winding arm 3, the belt 9, and the hollow press-type support 24. There is an air tube 1 inside the hollow drive shaft 5.
1 is inserted, and this air tube 11 is expanded by air sent from the hose 13 through the rotary joint 12, the hollow part of the support 24, and the tube mouth 11a, and contracts when the air supply is stopped. . A plurality of radial through holes 14 are formed in the hollow drive shaft 5, and intermediate members 15 are inserted into each of the through holes 14 so as to move up and down as the air tube 11 expands and contracts. When the hollow drive shaft is driven, when air is sent in to expand the air tube 11, the intermediate member 15 is pushed out in the radial direction and comes into contact with the inner peripheral surface of the collar 4, causing the collar to rotate due to friction.

As the collar 4 rotates, the pole of the locking mechanism 1B, which is a one-sided clutch provided on the outer periphery of each collar, protrudes from the outer periphery of the collar and restrains the inner periphery of the winding core C.
It rotates. Note that by adjusting the amount of air fed into the air tube, the frictional force between the collar and the intermediary member can be changed and the torque transmitted from the hollow drive shaft to the collar can be adjusted. Note that if the circumferential speed of the sheet roll becomes smaller than the sheet supply speed during winding, problems such as sheet loosening will occur. The hollow drive shaft is rotated, and excess speed is absorbed by slipping the collar and intermediate member.

In addition, air is supplied to the air tube by providing a rotary geoind on the winding shaft without passing through the winding core support, etc., and connecting an air supply hose to the rotary geoind part through a coupler joint, etc. It may also be installed directly.

FIGS. 8 and 9 are examples showing how the core or the winding shaft is supported on the core support A; Copper type support 10
Fig. 8 shows a state in which the winding core C is attached via the winding core C, and a state S in which the friction type winding shaft 1a introduced in Fig. 5 is attached (Fig. 9).

Reference numeral 19 denotes a clamp mechanism provided on the winding arm 3, which commonly clamps the support shaft 20 of the support lO and the support shaft 21 of the friction type winding shaft 1a. and support lO and volume lihla
is rotationally driven by a drive mechanism (not shown) via a belt 22 and a gear 23. Note that by clamping the support shafts 20 and 21 with the clamp mechanism, the gear 23
and a gear portion (
Needless to say, the winding shaft 1a in this embodiment is adapted to feed air from a hollow support 24 (not shown) that supports the other end (not shown). There is.

Although the present invention has been described above with reference to a small number of embodiments, it goes without saying that the embodiments thereof can be varied and applied in various ways depending on the conditions of implementation and the like.

For example, all of the illustrated embodiments were applied to winding up a sheet roll whose width was narrower than the approach limit width of the core support; The present invention can be similarly applied even to a specification in which only narrow sheets are divided.

There are various types of friction type winding shafts. ■ A rod is passed through the hollow drive shaft, and a cam is installed on this rod at a position corresponding to the intermediate member. By pushing and pulling the rod, the intermediate member is A type in which the member is moved up and down to make contact with the inner periphery of the collar, ■It is fitted onto a hollow drive shaft, and each collar forms an inclined surface on the opposing end surface of the pair, and the tip of the intermediary member matches the above end surface. A type in which the intermediary member generates an axial pressing force on the collar by a wedge action when pushing one end face of the collar and transmits the drive to the winding core. By extrapolating a large number of rotatable and axially movable collars or transmission rings and collars, and squeezing this group of collars in the axial direction from both sides, friction is generated between one collar end surface or between one collar end surface and the transmission ring. There are types that are rotationally driven by force, and the type is not limited to the type shown.

<Effects of the Invention> According to the present invention, even if the width of the narrow sheet is less than the approach limit width between the core supports, which was previously impossible with this type of slitter winder, It becomes possible to simultaneously wind up the sheets without affecting the winding of the sheets. Therefore, a single slitter winding machine can wind up narrow sheets with an extremely wide range of widths, that is, it is possible to diversify the division specifications, and it is possible to improve work efficiency and, by extension, productivity. Furthermore, if it is clear that a defective part such as an extremely narrow wrinkle exists continuously in the sheet running direction of the belt-shaped sheet, only that part can be wound up, so other normal parts are not wasted. There's nothing to do.

In addition, the number of narrow sheets varies greatly depending on the division specifications,
Even in cases where the number of core supports is reduced, there is no need to prepare or move a large number of core supports as in the past, which reduces the labor of the operator and shortens the preparation time for dividing. can be measured.
