Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention involves unwinding a strip-like sheet of metal foil, paper, plastic film, etc. from an original roll, dividing it into a plurality of strips, and distributing them to left and right winding positions. This invention relates to a thrifter rewinder for winding up.

(Prior art) Conventionally, for example, a slitter rewinder for aluminum foil or copper foil
In this system, a supporting device for the raw roll, a feeding device for the strip-shaped sheet, a slinter, and a winding device on the left and right sides are arranged in sequence in the horizontal direction, and during winding, the strip-shaped sheet passes horizontally through the slitter into multiple strips. The divided sheet strips are alternately distributed and wound from the slitter section to the winding shafts at left and right winding positions located beyond the slitter section. During the winding preparation work, the operator manually passes the leading edge of the belt-shaped sheet rewound from the original fabric roll along the belt-shaped sheet path to the slitter, and from the slifter, the leading edge of the divided belt-shaped sheet that comes at a ratio is rolled up on the left and right sides. They were alternately distributed and passed through the winding shaft at the take-up position.

(Problem to be Solved by the Invention) However, in the conventional structure in which part of the slitter and the left and right winding positions are sequentially lined up in the horizontal direction, and the divided strip sheets are alternately distributed to the left and right winding positions, The traveling length of the divided strip sheet from the slitter to the left and right winding shafts is longer at the winding position located at the rear. However, if the running length of the split strip sheet from the slipper to the winding shaft becomes long, the split strip sheet may become misaligned in its width direction during winding, and the take-up roll is likely to be defective.

In addition, the operator manually guides the leading edge of the strip sheet to the slitter during winding preparation, which places a heavy burden on the operator.
Furthermore, it is difficult to pass the belt-shaped sheet to the slipper without shifting or loosening.

Then, when the leading edge of the strip sheet reaches the slitter 6, the strip sheet is fed to a certain length in order to correct the misalignment of the strip sheet and take up the slack, or to remove the damaged part when guiding the strip sheet. It is also necessary to further compare the feed from the comparison roller.

Therefore, the above-mentioned belt-like sheet sent out before being properly divided by the slitter is wasted. Furthermore, the split strip sheet that is distributed to the rear winding position is longer than the split strip sheet that is distributed to the front winding position, and the excess portion must be cut and removed before being attached to the core, resulting in a lot of waste ( Become.

In addition, in order to sort and pass the divided strip sheets from the slitter to the take-up shaft, it is necessary to feed each divided strip sheet past the winding position on the front side and to the winding position located after it. Poor workability.

Therefore, with conventional slitter-rewinders, there is a lot of waste of strip sheets during preparation for winding, and workability is poor.Moreover, the path length from the slitter to the winding shaft is kept as short as possible (to obtain high-quality winding rolls). It wasn't enough for that.

SUMMARY OF THE INVENTION An object of the present invention is to provide a slitter rewinder that has good workability during preparation for winding, reduces wastage of a belt-shaped sheet, and can obtain a high-quality winding roll.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a feeding roller for the belt-like sheet rewound from the original fabric roll, and a vertically or substantially vertically downward direction from the feeding roller. A slitter is provided below the feed roller that divides the descending strip sheet into a plurality of split strip sheets in the longitudinal direction, a pair of left and right sorting guide rollers are provided directly below the slitter, and a slitter is provided diagonally below the slitter. A winding shaft is provided at the left and right winding positions at the same distance or approximately the same distance from the slitter, respectively, and winds up the divided strip sheet guided through the sorting guide roller, and the winding shaft is disposed at the left and right winding positions, respectively, and winds up the divided strip sheet that has been guided through the sorting guide roller, and the winding shaft that winds up the divided sheet that has been rewound from the original roll. The present invention is characterized by comprising a conveyance mechanism that conveys the leading end of the belt-like sheet to the feed ratio roller in a state in which the belt-like sheet is spread along the path of the belt-like sheet.

Further, the conveying mechanism may include a sheet suction conveyor between guide rollers in the path of the belt-shaped sheet.

Further, it is preferable that the delivery roller includes a nip roller that takes a receiving attitude and a delivery attitude.

Further, the conveyance mechanism may include belt conveyors on both sides of the belt-shaped sheet between guide rollers that create a path for the belt-shaped sheet.

Furthermore, the conveyance mechanism includes a holding device that holds the leading end of the strip sheet, and a holding device that supports the holding device and transports the strip sheet from a receiving position to a release position downstream of the delivery roller in the width direction of the strip sheet. It may also consist of a transfer mechanism provided on both sides.

(Example) The present invention will be explained below with reference to illustrated embodiments.

Figures 1 to 4 show a first embodiment of the present invention.
As shown in the figure, a feed-out roller 2 is provided diagonally above the original fabric roll l at a predetermined unwinding position. Raw roll 1
is supported by a raw roll support mechanism (not shown). The feed ratio roller 2 is a driven roller. Then, the belt-shaped sheet SO rewound from the original fabric roll 1 can be sandwiched between the nip rollers 3, rotated, and sent downward.

Directly below the feed roller 2, a plurality of pairs of rotational forces 4a, 4 are provided.
A slitter 4 with a is provided.

The slipper 4 can divide the strip-shaped sheet SO into a plurality of divided strip-shaped sheets S in the longitudinal direction. Also, the belt-shaped sheet SO that is sent out from the delivery roller 2 and descends in the vertical direction is the rotary blade 4a.

It is arranged so as to reach the sheet cutting point between 4a. Note that the slitter is not limited to the shear cutter, and a known one such as a score cutter may be used.

In this embodiment, a pair of left and right auxiliary rollers 5.5 are provided directly below the slider 4 for pinching the divided strip-shaped sheet S and assisting in its feeding during preparation for winding. Furthermore, a pair of left and right sorting guide rollers 6.6 are provided directly below. The sorting guide roller 6.6 guides the divided strip-shaped sheet S from the delivery roller 2 in a vertical or substantially vertical direction during winding. By doing so, the divided strip-shaped sheet S is not directly divided into left and right parts in the slitter 4, so that the slitter 4 can obtain a normal strip-shaped sheet division function.

There are left and right winding positions diagonally below the left side and diagonally below the right side of the slitter 4. At the left and right winding positions, winding shafts 7, 7 are provided at the same distance or approximately the same distance from the sheet cutting point of the slitter 4 in the distance of the divided strip sheet path, and are supported by a winding mechanism (not shown). A certain 0-winding shaft 7 is capable of winding up divided strip-shaped sheets S that have been individually distributed through a distribution guide roller 6.6 around a core C attached thereto. In this embodiment, the winding shaft 7 is a so-called individual friction winding shaft. Although not shown in detail, each of the friction winding shafts has a plurality of winding cores or core supporting rings arranged and fitted in the longitudinal direction on the outer peripheral surface of a rotationally driven central shaft. Then, a friction member held on the central axis so as to rotate together with the core or ring is pressed against the friction engagement surface of the winding core or ring with a required force to adjust the friction force of the engagement surface, and the friction force of the engagement surface is adjusted. The structure is such that the required torque is transmitted to each core or to the core support ring. Moreover, it is possible to simultaneously wind up a plurality of divided strip-shaped sheets.

Between the sorting guide roller 6 and the take-up shaft 7, according to this embodiment, there are a nip roller 8.8a and guide rollers 9, 10 for guiding the divided strip sheet S from the sorting guide roller 6 to the take-up shaft 7. is the provision. The left and right nip rollers 8, 8a and the guide rollers 9, 10 are supported by swing arms 11.11, which are arranged symmetrically below the left and right sorting guide rollers 6.6, respectively. The swing arm 11 is supported so as to be swingable about a shaft 12 at its upper end. A pair is formed on both sides in the width direction (perpendicular to the paper surface of FIG. 1) of the traveling path of the divided strip-shaped sheet S. It can be driven and oscillated by a oscillation drive mechanism 13 consisting of a fluid pressure cylinder device.

Immediately below the sorting guide roller 6.6, there is provided a sorting mechanism 14 for alternately distributing the leading edge of the divided strip sheet S to the left and right. The swing arm 11 is provided with a transfer mechanism 16 for the holding device 15. The holding device 15 can simultaneously hold and hold the tips of the divided band-shaped sheets S sorted by the sorting mechanism 14. The transfer mechanism 16 then moves the holding device 15 to the nip rollers 8, 8a.
A holding device 15 holding the leading end of the split strip sheet S can be guided and conveyed along the split strip sheet path from the split strip sheet S to the guide roller 10. Further, at the tip of the swinging arm 11, there is a winding section for gluing the split strip sheet S, which is held by a holding device 15 and taken out near the winding shaft 7, onto the winding shaft 7 and cutting off the excess tip. A cutting mechanism 17 is provided.

A guide roller 1 is provided between the raw roll 1 and the feed roller 2 for guiding the strip sheet SO along the strip sheet path.
8.19.20 is set. The guide rollers 19,20 are in this case driven rollers. Guide rollers 18 and 19
, sheet suction conveyors 21, 22, 23 are provided along the belt-shaped sheet path between the guide rollers 19 and 20, and between the guide roller 20 and the feeding pressure roller 2. The sheet suction conveyors 21, 22, and 23 are conveyors that can convey the belt-shaped sheet SO while suctioning it, and each has a similar structure. In this case, as shown in FIG. 2, a circulation belt 25 is provided with suction holes 24 at predetermined intervals over its entire length, and a suction hole 26 is provided below the circulation belt 25 and communicates with the suction holes 25. It is equipped with a decompression box 27. Further, the circulation belts 25 are arranged in four rows and wound around the rows on both sides of the decompression box 270. Also, the suction hole 26
are arranged in large numbers in the longitudinal direction of the circulation belt 25 on the contact surface with the lower surface of the belt. In addition, in FIG. 2, suction holes 24 and suction holes 2 for circulation belts other than the topmost circulation belt are shown.
6 is not shown, and the circulation belt 25 does not need to have four rows. When conveying a strip sheet, the circulation belt 25 is driven by a drive mechanism (not shown) and circulates,
The inside thereof is depressurized by a decompression pump (not shown), and the belt-shaped sheet SO on the circulation belt 25 can be adsorbed through the suction hole 26 and the suction hole 24. Then, when the belt-shaped sheet SO is placed on the circulation belt 25, the belt-shaped sheet SO
is transported on the circulation belt 25 in an adsorbed state. In this embodiment, the sheet suction conveyor moves forward to the belt-shaped sheet path while conveying the belt-shaped sheet, and retreats from the belt-shaped sheet path while winding up, by the action of an advance/retreat mechanism (not shown). However, it may be fixed at a position slightly retreating from the belt-shaped sheet path as long as it does not hinder the conveyance of the belt-shaped sheet.

According to this embodiment, the nip roller 3 paired with the feed roller 2 compares the advancing direction of the leading end of a belt-shaped sheet with a relatively strong layer, such as a metal belt, and the roller 2
In order to do this, the nip roller 3 has a bearing at the tip of a pair of swing arms 28 and 28 that can pivot concentrically with the center of rotation of the feed roller 2. It is supported by 29,29. When the bearing 29 is driven by the fluid pressure cylinder device 30 on the swing arm 28 to advance and retreat, the nip roller 3 is pressed against the feed roller 2 or separated from the feed roller 2.

Further, the rotating arm 28 is moved from the sheet receiving position (shown by a solid line in FIG. 4) to the sheet feeding ratio position by transmitting the rotation of the feed roller 2 via the clutch 31 and a series of transmission devices 32. (indicated by the chain line in Figure 4). Swinging of the swinging arm 28 from the sheet sending position to the sheet receiving position is performed by transmitting the driving force of the motor 33 to the transmission device 32 via the clutch 34.

When passing the leading edge of the strip-shaped sheet SO from upstream to downstream of the feed roller 2, the nip roller 3 moves the feed roller 2 on the rotating arm 28 attached to the sheet receiving position.
Move away from him and take a accepting stance. When the leading edge of the belt-shaped sheet SO passes between the feed roller 2 and the nip roller 3, the nip roller 3 presses the feed roller 2. At the same time, the rotating arm 28 rotates, and the nip roller 3 also rotates at the same speed as the rotation of the feed roller 2. When the swing arm 28 reaches the sheet feeding position, the nip roller 3 assumes the feeding position. Then, in this attitude, the belt-shaped sheet SO is sent out directly below from the delivery roller 2.

The guide roller 19 is equipped with a nip roller 35. The nip roller 35 waits in a receiving posture when the leading end of the belt-shaped sheet SO passes, and when the leading end of the belt-shaped sheet SO passes, it is pressed against the delivery roller 2. Guide roller 20
is equipped with a nip roller 36 which is supported by a rotating arm having the same structure as the nip roller 3 and has a similar fl. The nip rollers 3.35.degree. 36, each shown in solid lines in FIG. 1, are in the delivery position, and the dashed lines near them show them in the receiving position.

When rewinding the strip-shaped sheet SO from a new roll 1 and passing its leading edge along the travel path to the take-up shaft 7, the sheet suction conveyors 21, 22, 23 are activated, and the nip rollers 35, 36° 3 are operated. Each of the strips is placed in a receiving posture, and then an operator compares the leading edge of the belt-shaped sheet SO to the sheet suction conveyor 21 via the guide roller 19, and transfers the leading edge of the belt-shaped sheet SO to the sheet suction conveyor 21 with the leading edge extended. Let it absorb. Then, each of the driven guide rollers (including the motor if the rewinding mechanism uses a motor to rotate the web roll) such as the feed roller 2 in the slitter rewinder is rotated at an appropriate line speed. At this time, the feeding roller 2, the guide roller 19.
Sheet suction conveyor 21, 2 for rotational drive speed of 20
2. Slightly increase the transport speed in step 23 to create tension on the strip sheet SO.
The tip of O is the sheet suction conveyor 2 up to the feed roller 2.
1.22.23, it is guided along the travel route and conveyed to the feed roller 2. At this time, slipping occurs between each of the sheet suction conveyors 21, 22, 23 and the strip-shaped sheet SO, but the strip-shaped sheet SO is conveyed to the rollers 2 at a feeding ratio so as not to slacken. Note that the conveyance speed of each sheet suction conveyor 21, 22, 23 is adjusted (preferably) so that the amount of slip between these and the belt-shaped sheet SO is as small as possible.

When the leading edge of the band-shaped sheet S°0 reaches the feed-out roller 2, it changes direction directly downward. If the belt-shaped sheet SO is, for example, thin and has a weak waist, the tip of the belt-shaped sheet SO will move straight downward due to gravity, so it is sufficient to leave the swing arm 28 in the seat receiving position. If so, the rotating arm 28 is moved to the sheet feeding position and the nip roller 3 is placed in the feeding position.

The belt-shaped sheet SO sent out from the delivery roller 2 reaches the slitter 4 and is divided into multiple divided belt-shaped sheets.
) becomes S. Then, the leading edge of the divided strip sheet S descends directly below and passes between a pair of feed-out auxiliary rows 5, 5 and between a pair of distribution guide rollers 6.6, and furthermore, a distribution mechanism 14 provided directly below the distribution guide rollers 6.6. Then, the distribution board distributes them alternately to the left and right. The sorting mechanism may be one in which, for example, a sorting plate is kept at a standby position, and when the leading edge of the divided strip-shaped sheet descends and reaches the sorting plate, the sorting plate is moved to move the divided strip-shaped sheet in the sorting direction and sort it out. Special Public Service 1986-4
As disclosed in Japanese Patent No. 5136, there is a type in which the tip of the divided band-shaped sheet S is scooped up by a movable guide piece.

The respective leading ends of the divided strip sheets S sorted by the sorting mechanism 14 are gripped all at once by a holding device 15 waiting near the exit of the sorting mechanism 14. The holding device 15 is conveyed along the split strip sheet travel path to near the winding shaft 7 by the transport machine ELL116, and then
The leading end of the divided strip sheet S that has been conveyed to the vicinity is automatically attached to the winding core C by the winding and cutting mechanism 17. When the winding operation is started, the strip sheet SO is unwound from the original roll 1 and divided by the slitter 6, and each divided strip sheet S is wound around the respective winding core 15. As shown by the chain line in Fig. 1, during winding, the winding roll R
The swinging arm 11 swings in response to an increase in the radius of. Then, the guide roller 10 separates from the winding shaft 7.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, belt conveyors 21a and 21b, 22a and 22 are used to convey the leading edge of the belt-shaped sheet SO to the sending roller 2.
b, 23a and 23b are guide rollers 18 and 19, guide rollers 19 and 20. It is provided along the belt-shaped sheet path between the guide roller 20 and the feed ratio roller 2. These belt conveyors 21a and 21b, 22a and 22b, and 23a and 23b are respectively arranged on both the front and back sides of the belt-shaped sheet SO, and they pinch and convey the belt-shaped sheet SO, and they have no effect of adsorbing the belt-shaped sheet SO. This is different from the sheet suction conveyor of the first embodiment.

FIGS. 6 and 7 are drawings showing a third embodiment of the present invention. In this embodiment, a holding device 36 that pinches and holds the leading end of the belt-like sheet SO and its transport mechanism 37 are used to transport the leading end of the belt-like sheet SO rewound from the original fabric roll 1 to the sending roller 2. This embodiment differs from the previous two embodiments in that it includes a transport mechanism consisting of the following.

The holding device 36 has a first beam member 38 and a second beam member 38 as shown in FIG.
The band-shaped sheet SO can be held between the beam member 39 and the beam member 39. Then, the belt-shaped sheet SO is held at the receiving position indicated by the symbol ■ in FIG. 6, and the leading end of the belt-shaped sheet SO is released at the release position indicated by the symbol ■1 in the figure.

The holding device 36 is configured such that when the movable body 41 is pushed by the rond of the fluid pressure cylinder device 40 provided at the receiving position I, the movable body 41 moves, and the inclined surface 41a of the movable body 41 has an inclination angle smaller than the friction angle.
Then, the metal fitting fixed to the second beam member 39 is pushed up to press the second beam member 39 against the first beam member 38. Further, when the movable body 41 is pushed and moved by the hydraulic cylinder device 420 rod provided at the release position 11 shown in FIG. 6, the first beam member 38 and the second beam member 39 are opened. The first beam member 38 has both ends connected to the transfer mechanism 37.
It is supported by chains 43.43. The chain 43 includes the feed roller 2 and the guide rollers 18, 19.2.
As shown in FIG. 6, it is wound around a plurality of guide wheels 45 arranged as shown in FIG. When the guide wheel 45 is rotated by a drive mechanism (not shown) having a torque adjustment means for conveying the belt-shaped sheet so with an appropriate tension, the chain 43 is held along the belt-shaped sheet path from the receiving position 1 to the releasing position 1. device 36
circulates to transport. And chains 43 on both sides.
43 is interlocked and can move the holding device 36 in parallel.

The tip of the strip-shaped sheet SO unwound from the original fabric roll 1 is placed between the first beam member 38 and the second beam member 39 at the receiving position I, and the first beam member 38 and the second beam member 39 are When the holding member 39 is held closed and the chain 43 is circulated, the holding device 36 guides the strip SO along the strip sheet path to the roller 2. Release position H
When the holding device 36 comes to the position, the circulation of the chain 43 is stopped.
The fluid pressure cylinder 42 operates to separate the first beam member 38 and the second beam member 38.
The beam member 39 opens to release the band-shaped sheet SO. Note that the holding at the receiving position (2) can also be carried out by an operator instead of the fluid pressure cylinder device 40.

Although a small number of embodiments have been described above, the implementation thereof can be varied in various ways depending on the design conditions and the well-known techniques of the designer.

For example, the feed roller may not be paired with the nif roller, and the feed roller is not necessarily placed at the highest position, but a guide Q-roller may be provided above it.
After changing the traveling path of the strip sheet downward by this guide row, it may be received by the delivery roller, or the gap between the feed ratio roller and nif roller may remain closed when both rollers are in the receiving position. It is also possible to provide another roller between the feed ratio roller and the slitter.

Furthermore, the winding shafts at both winding positions are not limited to being supported at fixed positions, and during winding, they can be moved in opposite directions by swinging or sliding movements as the radius of the winding roll increases. There may be cases where it is supported.

Furthermore, when a touch roller, a roller with flanges at both ends that contact the end surface of the take-up roll, etc. is provided between the distribution guide roller and the take-up shaft, these may be supported by a support body capable of sliding movement.

Further, the slifter may be one that uses a laser or the like as long as it has the function of cutting and dividing the belt-shaped sheet.The zero winding shaft is not limited to each friction winding shaft, and the slitter rewinder is not limited to the one in the above embodiment. Although it is possible to obtain a plurality of winding rolls with approximately the same winding amount from a raw fabric roll, it is also possible to obtain a plurality of small winding rolls from one raw fabric roll.

Furthermore, the conveyance mechanism may be one that conveys the strip sheet using a laminar flow of air, and the holding device in the conveyance mechanism of the third embodiment described above is provided separately for each of the left and right transfer mechanisms to hold the strip sheet. It may be possible to partially hold both edges of the tip, and a belt lobe or the like may be used instead of the chain of the transfer mechanism.

(Effects of the Invention) Since the present invention is configured as described above, it produces the effects described below.

A slitter is provided below the feed roller, winding positions are further provided diagonally below the left and right sides of the slitter, and a set of left and right sorting guide rollers are provided below the slitter, so that the slitter and the left and right winding shafts are connected to each other. It is possible to make the lengths of the divided belt-like sheet running paths equal to the length of the divided belt-like sheet travel path, and to shorten the length of the divided belt-like sheet path from the slitter to each winding shaft at the left and right winding positions. As a result, there is no need to worry about large deviations in the width of the fed-out split strip sheet and the winding roll becoming defective, and the work of guiding the split strip sheet to the winding shaft without going against gravity. It has good workability and can be completed in a short time.

In addition, when attaching the split strip sheet to the winding shaft, unlike conventional methods, the path lengths from the sorting position to the left and right winding positions are different, so the leading edge of the split strip sheet distributed to one winding position is wasted. There is no problem of becoming.

In addition, since the distance from the slitter to the distribution position of the divided strip sheets can be shortened, there is no need to worry about overlap between adjacent divided strip sheets due to displacement of the divided strip sheets that translate between them. There is no fear that the side edges of overlapping split strip sheets will rub against each other and cause permanent distortion in the side edges.

Furthermore, even when a sorting mechanism is applied, stable sorting of the leading ends of the divided strip sheets can be achieved. It is also easy to automate subsequent work.

Further, the leading end of the belt-shaped sheet rewound from the original roll is conveyed in an extended state by a conveyance mechanism to a delivery roller along the path of the belt-shaped sheet, and further guided by the action of gravity from the feeding roller to a slitter. Then, it can be passed through the slitter as it is. Therefore, the work of passing the leading end of the belt-like sheet becomes easy, and there is no need for driving or work to correct misalignment or slack in the belt-like sheet, and waste of the belt-like sheet can be prevented.

Therefore, high quality winding rolls can be stably obtained.
A slitter rewinder with good workability can be provided with almost no wastage of the strip sheet during winding preparation.

When a suction conveyor is used as the conveyance mechanism, the holding force of the belt-like sheet due to the suction of the conveyor is not large and the belt-like sheet and the conveyor can slip. Even if the degree is bad, it can be corrected by the tension of the belt-like sheet during conveyance.

Therefore, no skill is required to prepare the leading end of the strip sheet for the suction conveyor.

Moreover, if the delivery roller is provided with nip rollers attached to the belt-shaped sheet receiving position and the delivery position, the reception and delivery of the belt-shaped sheet from the conveyance mechanism can be ensured.

In addition, if a belt conveyor is used as the conveyance mechanism, which has a belt conveyor installed on both the front and back sides of the sheet between guide rollers that create a path for the sheet, the sheet will be rigid and will tend to curl when rewound from the original roll. Even a belt-shaped sheet can be guided reliably.

Further, as a conveyance mechanism, a holding device that pinches and holds the leading end of the belt-shaped sheet, and a belt-shaped sheet width direction that supports the holding device and transports the belt-shaped sheet from a receiving position to a release position downstream of the delivery roller. By adopting a device equipped with a transport mechanism provided on both sides of the belt, the belt-shaped sheet can be accurately guided to the delivery roller, and the belt-shaped sheet can be applied even if the space around the belt-shaped sheet passage is small. It can also be applied to a variety of belt-shaped sheets with different sheet properties and thicknesses.

Furthermore, since the belt-shaped sheet contacts the holding device only at its leading end, there is no fear that the surface of the belt-shaped sheet will be scratched and become defective during conveyance.
