Abstract

PURPOSE:To enable rolling up each sheet belt into a high quality roll without effect of respective thickness differences of sheet belts which are slitted from a wide sheet with lateral thickness differences, by arranging a number of touchrolls fractuated in the axial direction. CONSTITUTION:A wire sheet rewound by a drawout roll 2 from an original textile roll 1 is slit-processed into a number of sheet belts S by a blade 4. The sheet belts S are divided into two winding shafts 5 I and 5II which are rotated respectively, and touchrolls 6 I and 6II driven through a micro-speed-change gear against the rotation speed of the drawout roll 2 are contacted to the winding shaft 5 I and 5II through the sheet belts S. The touchrolls 6 I and 6II adjust the tension of the sheet belts S, which are wound to the winding shafts 5 I and 5II. In this case, the touchrolls 6 I and 6II, which belong to the winding shafts 5 I and 5II, are arranged fractuated along the sheet axial direction, contacted to the respective winding shafts 5 I and 5II through the sheet belts S. Thus, each sheet belt can be wound up into a high quality roll without any effect of individual thickness differences of the sheet belts S.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is a wide sheet, for example, a large number of predetermined width sheets, which are unwound from a raw roll of plastic film, paper, metal foil, etc. This invention relates to a slitter winding device that slits a sheet band and winds up a roll of VC.

(Prior art) A large number of sheets slit on a wide sheet are distributed to two rotationally driven take-up shafts, and each take-up shaft is equipped with a series of touch rolls that rotate in conjunction with a feed roll. The wide sheet is brought into contact with the sheet band through the sheet band, and the tension of the sheet band is adjusted by one rotation of each series of touch rolls. Is there a variable speed in the transmission system between the feed roll and each touch roll? J4' The interposition of the JRi device was proposed by the applicant of the present patent in Japanese Patent Application Laid-open No. 37-J//! It is known from the publication No.
VC seems to be able to improve without c.

(The problem that the investigation aims to solve) However, since then, due to remarkable advances in manufacturing technology for wide sheets, especially plastic films, it has become possible to manufacture ultra-thin films with a thickness of less than 3 μm, and the sheet surface has also been finished extremely smooth. Ranru-sama VcZ Tsuta. On the other hand, in the field of post-processing such as printing, is there a problem with processing efficiency? In order to increase the winding speed, it is required that the sheet band slit to the required width be rolled as long as possible, with a large diameter, and with high quality.

The touch roll of the above 5-pin conventional device is a series of the same length as the winding shaft to which it belongs, and it contacts the winding shaft in a series through the whole of the sheet belt of nyyc in number to the winding shaft to which it belongs. , each sheet band is fed onto the take-up shaft.

Therefore, if the thickness of a wide sheet is completely constant in the width direction, each series of touch rolls will contact the associated winding @ shaft with a uniform contact force through the entire sheet band, and the entire sheet band will be supplied. It is possible to unwind the winding shaft with the same tension. However, in reality, the tolerance for the thickness of wide sheets is about /μ. , and the thickness of another sheet band applied to the other parts is /lμ, so by applying sheet bands of different thicknesses in this way, the contact force of the touch roll to the attached shaft VC can be increased. There is a difference between the part where the thick sheet is completely lost and the part where the thin sheet is hung.In particular, the part where the thin sheet is hung does not come in contact with the winding shaft through the sheet band, so it is difficult to wind the thin sheet. The adjustment effect of the supply tension sent to the shaft is lost, and at the same time, air enters the space between the winding layers 1c of this thin sheet band without limit, and the smooth and slippery sheet between the six sides of the sheet is smoothed by the air. Encourage and disfigure.

Furthermore, the contact force of the touch roll on the take-up shaft concentrates on the take-up crawl of the thick sheet band on the take-up shaft, and the density of the zero take-up roll becomes too high.

And this tendency shows that when the difference in thickness between sheet bands is 7μ, the diameter of the take-up roll changes by 111111 every time the sheet band is wound 100 times on the winding shaft, and the sheet band can be formed easily. When winding a long wire with a large diameter, the difference accumulates and becomes even more noticeable.

(Means for Solving the Problems) Therefore, the present invention proposes that a series of touch rolls, which had the same length in y as the conventional winding shafts, are subdivided and arranged in the axial direction, and are individually arranged through sheet bands. It is characterized in that it is brought into contact with the associated winding shaft.

(Function) In this way, in the present invention, the individual touch rolls segmented in the axial direction individually contact the associated winding shaft via the sheet band'.

In addition, the wide sheet unwound from the original roll/ is guided to the blade through all the nip rolls, and the slitted sheet band is finely divided by touch roll 61, tU-t, guide roll/S, and expander roll 76. etc. are all installed between the left and right inner frames. In addition, in order to attach the swinging arm 4, two splined or polygonal support shafts with a width of 7" are provided between the left and right inner frames, and each support shaft has a slide/gf swinging arm that can move in the direction of movement. The base of the swinging arm, one for each slide, can be rotated completely by lowering the number by the number of 1C, so that it can be fixed on the support shaft with a set screw, etc. The base of the swinging arm can be fully rotated by 1C lower, and can be rotated as needed for each slide. The contact force on the winding shaft 3I, !■ of each subdivided touch roll 6I, which is supported by a pair of swinging arms between the swinging MU arms, is set to R.
A contact pressure device 79 consisting of a spring type or pneumatic piston/cylinder is provided for adjusting rXd.

Two contact pressure devices installed on the cutting surface and the swinging arm.
, /l operate simultaneously. Moreover, on one side of each of the two slides that make up the pair of swinging arms, there is an intermediate gear /g'f that meshes with the gear 7' of the line shaft concentrically with the center of rotation of the swinging arm.
Storage, from this gear 7g', gear train, belt transmission, etc. are each subdivided into touch roll gears and belts? Rub it so that it rotates.

The reason why each slide/row is movable on the support shaft Vc is to accommodate changes in the width of the sheet band. Similarly, the gear 7' on the line shaft and the slitting blade ≠ are also fixed at a fixed position E' between the left and right inner frames. (R is set so that it can be changed, and the subdivision touch rolls 6I..., B)... are placed between the free ends of the pair of swinging arms to intersect with those that meet the new width of the sheet band.
C Make it removable. This means that the free end of each swinging arm is provided with a semicircular part that aligns with the half circumference of a '1411 receiver, which is similar to the shaft protruding from each end of the touch roll, and a similar semicircular recess. The entire lid is screwed into the free end of the arm, and the outer circumference of the bearing is placed between the two semicircular recesses. Appropriate means can be employed, such as fixing it in a removable manner.

Six losses? To start, roll the sheet band wound up mJ times? A cylindrical winding core made entirely of iron is installed at the position where the d touch roll contacts each winding shaft removed from between the left and right outer frames for the outside f, and the winding shaft is installed on the outer frame and separated into O. Either fix the tip of each sheet band to be wound with IC adhesive tape, etc. on the winding core, or install each winding shaft first, and divide the tip of each sheet band to be wound in one (b) or several times each into subdivisions. It is wound around the position where the touch roll comes into contact and fastened with adhesive tape or the like to form a core directly connected to the sheet band VC.

Next, move the left and right inner frames forward, and each set of subdivision touch rolls 6I... is taken up on the winding shaft! 11 Elasticity of each sheet band 4 caused by the tension 1+ of one strip of the feeding roll λ (Fig. 6), which is brought into contact with the tray!

It can be gradually reduced by the well-known taper control.

The retraction of the left and right inner frames to the outer frame VCq is performed stepwise or continuously using the piston cylinder.

→, it is 79μ, and even if there is a difference in thickness, and as the roll progresses, the diameter of the roll 145j re-roll on the winding shaft of the sheet firefly is due to the accumulation of the difference in thickness! Even if the change occurs, each subdivision touch roll is only in contact with the sheet strip that it feeds into the Kaede winding shaft, so when the control of the left and right inner frames is insufficient (the sheet strip When the thickness of the sheet is thicker than the nominal thickness, it is rolled up with the contact pressure device/l; the swing arm r swings in the milling direction, and conversely, If the left and right inner frames are controlled to be too thin, the swinging arm will use a contact pressure device to apply a force to the winding shaft and shake it, thereby reducing the difference in sheet thickness and the winding shaft. According to the change in the diameter of the take-up roll above, the contact force of each subdivision touch roll to the take-up shaft is made uniform, and each sub-division touch roll feeds the sheet band to the take-up shaft with uniform supply tension and winds it. .

In this #41 implementation tarry, the winding shaft was installed on the fixed left and right outer frames, but the same effect can be achieved even if the winding shaft is installed on the left and right inner frames that move forward and backward.

In addition, the movement of the left and right inner frames forward and backward is not limited to the aforementioned driftwood pressure piston cylinder J, but a fixed rack pawl is meshed with one wheel of a gear substitute wheel of 7 frames on the left and right inner sides, and this wheel T motor is used. All other means can be used, such as rotating it, or passing a stationary square screw that rotates forward and backward through nuts provided on the left and right inner frames, and rotating it with a motor on this square screw.
