Abstract
The invention relates to a method or a device for carrying out a method for preparing a cotton wool end (E) of a line of cotton wool (B) for subsequent reprocessing of the same. Known devices for preparing a cotton wool end of a roll (W) usually operate by holding the cotton wool (B) in one or two clamping points and then tearing it apart. The actual tear line is not clearly defined. The aim of the invention is to remedy this problem. To that end, the line of cotton wool (B) is clamped across its width and the free end (E) extending beyond the clamping point (K) is separated immediately after the clamping point (K) by a current of pressurised air generated across more or less the width of the line of cotton wool (B). Said pressurised air current can be generated by a pressurised air nozzle (32) whose outlet (33) is situated adjacently and directly on the output side of the clamping device (K).
Description
The present invention relates to a kind of method and apparatus that is used for being prepared as the lap termination of the required web of road, back manufacturing procedure.
For the automatic joint of lap termination, for example in combing machine, the lap termination is prepared respectively, in the joint location zone of the lap termination of pulling out thin or thick position appear so that avoid in follow-up joint process.This joint of the lap of a new supply also can be applied in the combing preparation.The lap termination of Zhun Beiing is seen on the length direction of debatching direction and should be shown the cut-out limit one like this, and it is positioned on the approximate line of cut-out uniformly, and the lap termination should be pulled out in about most advanced and sophisticated mode here.In other words the lap termination than web slightly attenuation some.
From EP-A1-482 475 is known a kind of device arranged, wherein prepare to be positioned at lap termination on the take up roll by being located at two preparation devices between the take up roll.In the case, still be positioned at termination on the lap by an aspirator sucking-off and transfer to the zone of a fixing device.Lap keeps rotation in this process, till the existing enough length in the lap termination of determining institute's sucking-off by a sensor is positioned at the fixing device zone.In case after reaching this state, just being further rotated of lap stops by stopping take up roll, and makes the fixing device closure.And then Bi He fixing device is after on the whole width clamping web, and the reverse drive by take up roll is rotated lap round about.Therefore because the result of clamping action, the lap termination is broken between clamped position and lap supporting-point in the take up roll back or is separated.
Be positioned at the termination of the cut-out below the clamped position, mat one aspirator siphons away and throws away after fixing device unclamps.
With this device, in most of the cases can obtain one prepare good lap termination, it can be applicable to the automatic joint process in road, back.
But this situation once took place, and particularly in the time must processing the lamination coating that has than chopped fiber (short fiber), promptly the distance between the lap supporting-point on the clamped position of fixing device and the back take up roll is too big and can not obtain a cut-out limit that limits.
This means and cut off line or cut off the limit may appear on any position and be not on the accurate preposition between the supporting-point of lap on described clamping lines and back take up roll, because web has different structures and obvolvent length for its debatching length.
This may cause in the follow-up joint process that the lap termination is connected on the lap termination of pulling out, and two lap terminations superimposed is difficult to accurately control, causes in the joint process two lap terminations overlapping sometimes too much, and sometimes very little.
Therefore the object of the present invention is to provide a kind of method and a kind of device, can realize the accurate off-position of lap on the web length direction by it.
Advise a kind of method, wherein web is clamped on its width for this reason, and and then the free end of giving prominence to outside clamped position is being cut off after the clamped position with flowing in the pressurized air that is produced on the web width.
Also suggestion in addition: the web termination that is cut off by pressurized air stream siphons away from the clamped position zone by at least one other air-flow.
Can obtain the exact location that a lap termination cuts off line in the downstream of clamped position with this device.Therefore no longer as original cutting-off method the counter-rotating by take up roll realize, but only cut off by applying compressed air.Before the take up roll counter-rotating, fixing device unclamps again so that ready lap termination is placed on the lap again.
The length direction that the direct vicinity that pressurized air is preferably in the web clamped position is sentenced with clamped web transversely or at angle blows on the lap termination to direction.
The present invention can realize by another kind of device equally, a fixing device and a pressurized air nozzle that extends at the web Width have wherein been adopted, here the pressurized air nozzle is arranged on the outgoing side near fixing device, and its spout is the lap termination of giving prominence to facing to from fixing device.For the purpose of taking away the lap termination of being separated by the pressurized air nozzle, suggestion is provided with a suction channel at the outgoing side of fixing device.
For the purpose of the design and an in check air-flow that obtain a compactness, also advise fixing device is fixed on the suction channel, and the pressurized air nozzle is given prominence in suction channel with its spout at least.
The pressurized air nozzle can design like this, makes it that the spout of independent adjacent arrangement can be set.
It is as follows by the following examples other advantages to be elaborated, wherein:
Fig. 1 is the diagrammatic side view that has by the web inlet of combing head in the combing machine of air plant of the present invention;
Fig. 2 is the diagrammatic sketch of the fixing device among Fig. 1 when opening.
Fig. 1 represents that wherein a lap W is positioned on driven take up roll 3,4 by a cross-sectional plane of the inlet of the web on the combing head 1 of a combing machine.Be provided with one in the middle of below take up roll 3 and 4 and prepare the termination E that device 6 is used for preparing web B.Preparation device 6 is made up of a suction tube 8 and a suction channel 9 that imports in the pipe 8.So just be provided with 8 such passages 9 under the situation of 8 combing heads, they all import in the pipe 8.Be connected with a vacuum source of not representing in detail on the pipe 8, produce an air-flow from each passage 9 inflow pipes 8 by its, as shown by arrows.
Being provided with one in the upper area of passage 8 can be round axle 10 and the side wall member 11 of rotating, it within it side have an elastomeric clamping element 12.Clamping element 12 for example can be made by rubber.As shown in FIG., be hinged on cylinder 14 on the passage 9 with axle 15, clamping element 12 is pressed to web B that stretches in passage 9 and fixed sidewall parts 16 that are positioned at the opposite by one.Thereby form a K of clamping lines when appearing on the width of web B.
Also schematically express a nipper unit Z and a feeding roller SW in addition.The web 8 that rolls out from lap W is supplied to nipper unit Z by a pair of pressure roller 44.
On the position shown in Fig. 1 and 2, the driving of a pair of pressure roller 44 and nipper Z is out-of-action, have only when by take away device 42 a new ready lap termination E when pulling out lap termination E1 joint, it just works again.Pull out the preparation of lap termination E1 and for example can carry out, wherein this process is had detailed explanation according to preceding European patent No.455 171.
