Definitions
- the invention relates to a method and an apparatus for carrying it out the method for a cotton end of a cotton web for subsequent further processing prepare by cutting off the present cotton end.
- the cotton end of a cotton roll e.g. a combing machine it is necessary that the cotton end is prepared accordingly in the subsequent attachment process to a leaking cotton end, thin or thick spots to avoid in the area of the attachment point.
- Such an approach of a tracked Cotton wraps can also be used in comb preparation.
- the cotton end prepared in this way should be seen in the longitudinal direction of the rolling direction Show tear-off edge, which is approximately on a regular tear-off line, whereby the end of the cotton should taper off approximately. That means the end of the cotton is opposite the cotton swath slightly thinned out.
- Such a device is known from EP-A1-482 475, with a preparation device, which is arranged between the two winding rollers, the cotton end of the roll lying on the winding rolls is prepared. Doing so the end still in contact with the wad of cotton is sucked off by a suction device and transferred into the area of a clamping device. In this process, the cotton wrap turned until a sensor detects that the extracted cotton end is of sufficient length in the area of the clamping device. Once this Condition is reached, the further rotation of the winding is stopped by stopping the winding rollers prevented and the clamping device closed.
- the wrap is then When the clamping device is closed, the cotton swath over the entire Width jams by reversing the drive of the winding rollers in opposite directions Direction turned. As a result, the end of the wadding is between the clamping point and the point of contact of the cotton roll on the rear winding roller torn apart or separated.
- the end located underneath the clamping point is separated by a suction device vacuumed and disposed of after opening the clamping device.
- the tear-off line or edge can be at any and not exactly predetermined Place between the mentioned clamping line and the support line of the cotton roll located on the rear winding roller, especially since the cotton web is also related can have a different structure and adhesive length on their unwinding length.
- the object of the invention is therefore to propose a method or a device, by which an exact position of the wadding tear with respect to the Longitudinal direction of the cotton wool is made possible.
- the end separated by the compressed air flow the cotton wool web by at least one further air flow from the area of the Clamping point is suctioned off.
- the compressed air is preferably in the immediate vicinity of the clamping point of the cotton wool web and across or at an angle to the longitudinal direction of the clamped cotton web blown the end of cotton.
- the invention is also achieved by a device, wherein a clamping device and a compressed air nozzle that extended across the width of the wad of cotton be, with the compressed air nozzle adjacent and on the outlet side of the Clamping device is arranged and its outlet opening against that from the clamping device shows outstanding cotton end.
- a suction channel is arranged on the outlet side of the clamping device.
- the clamping device be attached to the suction channel and the compressed air nozzle protrudes at least with its opening into the suction channel.
- the compressed air nozzle can be designed so that individual side by side arranged nozzle openings are provided.
- Fig. 1 shows a cross section through the wadding inlet on a combing head 1 one Combing machine, in which a winding W rests on driven winding rollers 3, 4.
- a preparation device 6 arranged for the preparation of the cotton end E of the cotton wool B.
- the preparation device 6 consists of a suction pipe 8 and a suction channel 9, which opens into the tube 8.
- the preparation device 6 With eight combing heads there are eight such channels 9 available, all of which open into the tube 8.
- Vacuum source connected, creating an air flow from each Channel 9 in the tube 8, as indicated by an arrow, arises.
- a pivotable wall element In the upper area of the channel 8 there is a pivotable wall element about an axis 10 11 arranged, which has an elastic clamping element 12 on the inside.
- the clamping element 12 could e.g. are made of rubber.
- a cylinder 14 As shown schematically is a cylinder 14, which is articulated via the axis 15 on the channel 9, the Clamping element 12 against the cotton web B projecting into the channel 9 and the opposite one fixed wall part 16 pressed. This creates a clamping line K, which is present over the entire width of the cotton wool B.
- the cylinder 14 is with the pivotable wall element 11 via the axis 18 and the tab 19 connected.
- the cylinder 14 is via a valve 20 via the lines 21 or 22 supplied with compressed air.
- the valve 20 is controlled via the control unit S. and determines the direction of supply of the air supplied by the pressure source 24.
- a Sensor 26 attached, which is connected via line 27 to the control unit S.
- Sensor 29 is provided, which is connected to the control unit S via the line 30.
- a nozzle 32 is attached, the opening 33 in the Interior of the channel 9 shows.
- the opening 33 can consist of individual and side by side arranged openings exist, which are distributed over the width of the cotton wool are.
- the opening 33 could also be formed from a narrow slot be, which extends across the width of the wad of cotton and over the line 35 with Compressed air is fed, which is supplied via the pressure source 37.
- the control the compressed air is supplied via a valve 36 which is controlled by the control element 38 from the control unit S is controlled.
- the control unit S is via the line 39 connected to the control element 38.
- a removal device 42 pivotally arranged, which for removing the prepared Cotton wool end E about a schematically indicated nozzle element 43 tangential air flow to the winding W is generated.
- a more detailed description of this Setup is e.g. can be found in EP-A1-482 475. There are also more Details regarding the execution of the preparation device 6 can be found.
- a tongs unit Z with a feed roller SW is shown schematically.
- the cotton web B rolled off the roll W is passed over the pair of pressure rollers 44 fed to the pliers unit Z.
- the control unit S When this clamping position is reached, the control unit S the valve 36 is actuated, whereby the compressed air generated by the compressed air source 37 for Opening 33 of the nozzle 32 arrives.
- the compressed air pulse is set so that the cotton end E is separated directly behind the clamping point K in a defined manner. The This means that the dividing line is exactly on the line of the openings 33 Cotton end E is suctioned down and removed.
- the valve 20 is controlled again via the control unit and the cylinder 14 is pressurized with compressed air via line 21. This will cause the piston rod of the cylinder 14 retracted and the wall element 11 again in the in Fig. 2 shown position pivoted back.
- the winding rollers are then reversed again and the winding in the direction of the arrow P1 rotated so that the new cotton end E reaches the area of the removal device 42, via which it is removed and is transferred to the pressure rollers 44 or the outgoing cotton end E1.
- the start of the new cotton end E to the outgoing cotton end E1 is timed controlled or tuned so that in the area of the pressure rollers 44 an attachment parts without thick or thin places. Now the normal rolling process of the Cotton web B from the winding W take place in order to combed out the pliers unit Z in connection with a circular comb, not shown.
