Abstract

The device comprises two corrugating rollers engaged together. In order to prevent the part where the adhesive is applied to remedy the crack of the roll paper from being damaged to the corrugating roller when passing through, and also to prevent from stopping the running of the equipment for cutting off the part where the adhesive is applied., the corrugating rollers interrelate with two feeding rollers driven by the same drive wheel of the corrugating roller, and the both sides of the roll paper are seized for feeding. When the detection device detects an adhesive applied part, a first servomotor disengages the upper corrugating roller from the lower corrugating roller before the part passing through. Once the part passes, a second servomotor re-engages the both rollers immediately and by using an adjustable position limiting plane, the both corrugating rollers can be engaged at an engagement depth (i.e. corrugating depth) as precisely as before.

Description

A kind of wrinkling device of roll web that makes

The present invention relates to a kind of wrinkling device of roll web that makes, it comprises at least two crease roller that are in the state of being meshing with each other, and roll web is carried processed between crease roller; The present invention also relates to the use of this device simultaneously.

As everyone knows, in the production of cigarette filter, employed creping is to use the roller that has groove to make roll web wrinkling.Employed roll web is long and is wound on the big storage paper bobbin.Up to now, in the production of these roll webs or roll in the process, can not avoid tearing often of roll web.Like this, just have to use adhesive tape they to be sticked together in the tear place.In any case the viscose glue on the roll web that will be wrinkling partly is very harmful.This is because the processing of crease roller is very accurate and through quenching, so they are very expensive, and institute has very little gap when using accordingly thin teeth groove and teeth to be meshing with each other.They partly are highstrung for aforementioned viscose glue, and therefore crease roller and begin to be damaged.When viscose glue partly passes through between the crease roller, crease roller is not durable very much.For avoiding these, up to now, customary way is outwards to be provided with designed mark in the viscose glue side partly of storage paper bobbin.When the roll web of crossing when mark is wrinkling, before markd viscose glue part is by wrinkling device, stop wrinkling device and roll web, and cut away viscose glue partly, use micromatic setting to remove crease roller simultaneously, be inserted into again between the crease roller separately cutting away viscose glue roll web partly, then, re-using micromatic setting makes crease roller turn back to the original state that is meshing with each other.Make this wrinkling device accelerate to desirable speed subsequently, and regulate space between the crease roller again, till reaching needed wrinkling degree by this micromatic setting.

Yet above-described complicated approach has greatly limited maximum wrinkling speed.

Therefore, the objective of the invention is to make the device of mentioning shortcoming more than a kind of having avoided, promptly viscose glue partly by the time the wrinkling device that need not shut down.

For this purpose, according to the present invention, under the situation of the sort of device of mentioning at first, this crease roller is linked on the drive unit running jointly with at least two, and the conveying roller that is suitable for meshing the roll web opposite face is associated; The position of engagement and one do not limit them and are meshing with each other between the degree of depth and adjustable confined planes at one, but crease roller is quick adjustment mutually, one to two crease roller of major general is linked on the fast adjuster, handle this fast adjuster synchronously with the transporting velocity of roll web, its synchronous manipulation is to finish by the checkout gear that is installed in crease roller input side front; This checkout gear is used to detect not by wrinkling and with the roll web that is cut off partly, so that before the part that will cut away is passed through, make crease roller just be in not engagement, after the part that will cut away was passed through, crease roller was got back to their original operating positions again.

When this crease roller engagement, might not need conveying roller also at transfer position.Therefore easily, between an inoperative position and transfer position, but this conveying roller is quick adjustment mutually; At said transfer position, conveying roller is to be in the state that is meshed with the roll web that will carry, and at least one is linked on the fast adjuster in two conveying rollers; And crease roller and conveying roller are adjustable in this position, so as to make have only in the roller a pair of at one time in will carry or will be in engagement by wrinkling roll web.Advantageously, be installed in rotation on respectively on two shared supports at the roller on the same side of the roll web of handling, and these two supports can rotate round a common axis that is parallel to roll shaft each other, and have at least one to surge or pneumatic servo booster is installed between two supports, be used to make two supports on axle, to relatively rotate.

When the device running, be easily inserted in the wrinkling device for making roll web, an air nozzle device is installed in crease roller input side front.Air nozzle points to formed space between conveying roller, so that when needing roll web between conveying roller, it can be inserted conveying roller, and if desired, also can point to the space that forms between crease roller.

Also advantageously, checkout gear also drives a roll web shearing device that is installed in crease roller outlet side back, so that cut away the part that need cut away from roll web with this roll web shearing device.

The present invention also relates to prepare to be used as the man-hour that adds of cigarette filter, make the use of the wrinkling device of roll web according to the present invention.

Advantageously, contain the cigarette filter that does not play wadding for removing, checkout gear and roll web are carried synchronously and are used, so that irrelevant and control the filter tip device of dishing out with the roll web transporting velocity, this device of dishing out is installed in the back that produces the cigaratte filter shearing device on the machine exit end near cigaratte filter.

Describe the present invention in detail below in conjunction with the cigarette filter process units, and with reference to the embodiment of the apparatus of the present invention that provide in the accompanying drawings.As shown in drawings, in this illustrational system, the roll web of extracting out from storage paper bobbin 12 offers wrinkling device 5 by adjusting wheel 4.In conveying, roll web 2 is by a photoelectric detection system 6.

Wrinkling device 5 have two crease roller 8,8 that are in engagement ', this crease roller adopts known method to make, its outside has teeth groove and the teeth on the circumferencial direction.Roll web 2 be transported to crease roller 8,8 ' between process.

Crease roller 8,8 ' be linked on the drive unit, turn round jointly and be suitable for meshing the conveying roller 9,9 of roll web 2 opposite faces ' be associated with two.

Crease roller 8,8 ' can use pneumatic servo boost motor 14,15 very promptly to regulate, pneumatic servo boost motor 14,15 include a cylinder and the piston that can slide and be coupled to a piston rod in cylinder.By a cam 10 accurately regulate and supporting surface 11 between the gap limit the degree of depth that meshes between crease roller, and supporting surface 13 is also similar adjustable by cam 12, define the position of engagement not or conveying roller 9,9 ' on pressure.More than said confined planes make by elastomeric material.For this purpose, 8 of the roller 8,9 of roll web 2 the same sides and opposite side ', 9 ' respectively be fixed on two common holder 16,17, and shared support 16,17 can relatively rotate around a common axis 18 that is parallel to roll shaft.

With such method, conveying roller 9,9 ' mutually also can promptly be regulated, and its adjusting is not being carried out between the position of engagement and transfer position.When transfer position, conveying roller 9,9 ' be is in the state that is meshed with the roll web 2 that is transferred.Crease roller 8,8 ' and the result that conveying roller 9,9 ' adjusting is produced be in making at one time, two pair rollers 8,8 ' and 9,9 ' in to have only a pair of be to be in and the state that will carry or will wrinkling roll web 2 not be meshed.

As mentioned above like that, the photoelectricity roll web checkout gear 6 of the roll web 2 that detection is just being carried is installed between reel 1 and the adjustment roller 4.Checkout gear 6 is used to detect on the roll web 2 must be not by wrinkling viscose glue partly, with avoid damaging crease roller 8,8 '.

The output signal of device 6 is provided to a signal processing apparatus 21 with velocity sensor 7 signals that produce, expression roll web 2 transporting velocities.Signal processing apparatus 21 is by the controller 22 of pipeline 23 control servo motors, so that before viscose glue part (not by wrinkling part) is passed through, do not consider the transporting velocity of roll web, pneumatic servo boost motor 14 is immediately their out of mesh positions of crease roller 8,8 ' take to, and after viscose glue partly passed through, pneumatic servo boost motor 15 made them accurately turn back to their original running positions immediately.

Roller 9 ' as roller 8 ' be installed on the same rotatable support 17, if the not position of engagement of roller 8 ' move to, its running of conveying roller 9 ' automatically move to is the position of engagement, so that in fact roll web 2 suffered pullings are not interrupted.

Required amount of movement approximately is 1 to 2 millimeter, and moving is to carry out on the position of crease roller 8,8 ' and conveying roller 9,9 ' meshing roll web.The size of roller 8,8 ' wrinkling tooth (big modulus) is to determine like this, promptly when their throw off engagement with roll web, they still keep engagement mutually, just they remain with an interdental space that is increased, so that the viscose glue on the roll web 2 in carrying on the one hand partly can not damage roller 8,8 ' tooth, and on the other hand, roller 8,8 ' again can turn back to their wrinkling position reliably.When the engagement of roller 8,8 ' disengagement and roll web 2, toothed roller is still run-in synchronism mutually, just remains with an interdental space that is increased, to avoid the danger of any infringement.

A shared driving wheel 3(dotted line) dot equally by gear wheel 19() and tooth-shaped conveying belt 20 driven rollers 8,8 ' and roller 9,9 '.

When checkout gear 6 detects in the conveying viscose glue on the roll web 2 partly the time, the signal that offers device 21 also advantageously guarantee the to have slowed down transporting velocity of roll web 2, till viscose glue has partly been removed, and roll web 2 increases to its original speed again subsequently.

When the device starting, for roll web 2 being inserted in the wrinkling device 5 easily, at conveying roller 9,9 ' front an air nozzle device 24 is installed, and air nozzle point to conveying roller 9,9 ' between the space so that roller 9,9 ' between insert roll web 2 beginning partly.

In the course of conveying of roll web 2, roll web 2 be slide in the horizontal direction some guide rollers (not providing) and pass roller 9,9 ' and 8,8 ' between.

Certainly, can adjust respectively rapidly roller 8,8 ' and 9,9 ', and be not to use the rotating support 17 of common land.

After roll web 2 came out from wrinkling device 5, using known method was that an air nozzle 25 is blown out one with roll web 2, forms the paper thigh with garden shape cross section.Subsequently, it is offered a known cigaratte filter process units 26, there, be wrapped in this paper thigh outside with wrapper paper 27, and make a bonding cigaratte filter of seam longitudinally.

An exit that is installed in device 26 by the filter tip shearing device 28 that constitutes around the rotating knife of trunnion axis.Filter tip shearing device 28 has nothing to do with the filter tip transporting velocity and the clavate filter tip is cut into the equal lengths section.

Filter tip after the cut-out is sent to an orientation and the device 29 of dishing out, and device 29 for example can be according to the specification manufacturing of No. the 619846th, Swiss Patent.

Device 29 has cylinder 30 and an air nozzle 32 of collecting the filter tip with groove by one to be formed, and air nozzle 32 can be used so that dishing out of defective filter tip is under the accurately control by magnetic valve 31 controls.Subsequently, irrelevant with the transporting velocity of roll web 2, come control valve 31 by signal processing apparatus 21, so that not being contained, all are dished out as substandard product through the filter tip of wrinkling paper.

This device can be produced the cigaratte filter of being made by wrinkling paper with the speed (for example: 400 meters/minute or more) that is higher than existing device, and this device is not interrupted running because of the viscose glue of roll web part (it has hindered wrinkling processing).

For example this device also can be used for producing storage ink device, to replace the production of cigaratte filter.

For example also can be used to process the cleaning paper of making by wrinkling paper according to wrinkling device 5 of the present invention.
