Definitions
- the invention relates to a method or to a device for carrying out the method to prepare a cotton end of a cotton web for subsequent further processing
- the cotton wool is prepared accordingly in order to avoid thin or thick spots in the area of the application point during the subsequent application process to a running cotton wool end Also used in the preparation of the chamber
- the cotton wool prepared in this way should have a tear-off edge when viewed in the longitudinal direction of the unwinding direction, which is approximately on a uniform cutting line, with the cotton wool end tapering to a point. This means that the cotton wool end is slightly thinned compared to the cotton wool web
- Such a device is known from EP-A1-482 475, wherein the cotton end of the lap lying on the lap rollers is prepared by means of a preparation device which is arranged between the two winding rolls suctioned off and transferred into the area of a clamping device In this process, the cotton roll is rotated until it is detected by a sensor that the extracted cotton end is in the area of the clamping device for a sufficient length. As soon as this condition is reached, the further rotation of the roll is stopped by stopping the Winding rollers are prevented and the clamping device is closed.
- the tear-off line or edge can be located at any and not exactly predetermined location between the mentioned clamping line and the support of the cotton roll on the rear winding roller, especially since the cotton web can also have a different structure and adhesive length with respect to its unwinding length
- the object of the invention is therefore to propose a method or a device by means of which an exact position of the wadding tear in relation to the longitudinal direction of the wadding web is made possible
- a method is therefore proposed in which the cotton web is clamped over its width and the free end protruding beyond the clamping point is separated directly after the clamping point by means of a compressed air flow generated approximately over the width of the cotton web Furthermore, it is proposed that the end of the cotton web separated by the compressed air flow be sucked out of the area of the clamping point by at least one further air flow
- the compressed air is preferably blown onto the end of the cotton wool in the immediate vicinity of the clamping point of the cotton wool web and transversely or at an angle to the longitudinal direction of the clamped cotton wool web
- the invention is also achieved by a device, wherein a clamping device and a compressed air nozzle, which extend over the width of the wadding web, are used, the compressed air nozzle being arranged adjacent to and on the outlet side of the clamping device and its opening against the cotton end protruding from the clamping device shows
- a suction channel be arranged on the outlet side of the clamping device
- the clamping device is attached to the suction channel and that the compressed air nozzle protrudes at least with its opening into the suction channel
- Fig. 1 is a schematic side view of the wadding inlet of a comb head of a comb machine with the compressed air device according to the invention
- Fig. 2 is a representation according to Fig 1 with the clamping device open
- FIG. 1 shows a cross section through the wadding run on a comb head 1 of a combing machine, in which a roll W rests on driven winding rolls 3, 4.
- a preparation device 6 for preparing the wadding end E of the wadding web B.
- the preparation device 6 consists of a suction pipe 8 and a suction channel 9, which flows into the tube 8. With eight comb heads, eight such channels 9 are then available, all of which flow into the tube 8.
- a vacuum source not shown, is connected to the tube 8 , whereby an air flow from the respective channel 9 into the tube 8, as indicated by an arrow, arises
- a pivotable wall element 11 is arranged about an axis 10, which has an elastic clamping element 12 on the inside.
- the clamping element 12 could be made of rubber, for example.
- a cylinder 14, which is connected via the axis 15 is articulated on the channel 9, the clamping element 12 is printed against the cotton web B projecting into the channel 9 and the opposite fixed wall part 16. This results in a clamping line K which is present over the entire width of the cotton web B.
- the cylinder 14 is connected to the pivotable wall element 11 via the axis 18 and the bracket 19.
- the cylinder 14 is supplied with compressed air via a valve 20 via the lines 21 or 22.
- the valve 20 is controlled via the control unit S and the direction of supply of the air , which is supplied by the pressure source 24, is intended for monitoring the position of the clamping element 12 or the axis 18 Sensor 26 attached, which is connected to the control unit S via the line 27.
- a further sensor 29 is provided in the interior of the channel 9, which is connected to the control unit S via the line 30 directly below the clamping point K
- a nozzle 32 is attached, the opening 33 of which points into the interior of the channel 9.
- the opening 33 can consist of individual openings arranged next to one another, which are arranged distributed over the width of the cotton web.
- the opening 33 could also be formed from a narrow slot. which extends across the width of the wad of cotton and is supplied with compressed air via line 35, which is supplied via pressure source 37.
- the supply of compressed air is controlled via a valve 36, which is controlled by control unit S via control element 38.
- the control unit S is connected via line 39 to control element 38 on axis 5 of winding roller 3 a removal device 42 is pivotally arranged, which generates an approximately tangential air flow to the winding W for removing the prepared cotton end E via a schematically indicated nozzle element 43.
- a more detailed description of this device can be found, for example, in EP-A1-482 475 Details regarding the execution of the preparation device 6 can be found
- a forceps unit Z with a feed roller SW is shown schematically.
- the cotton web B rolled off the roll W is fed to the forceps unit Z via the pair of pressure rollers 44
- the control unit S actuates the valve 36, as a result of which the compressed air generated by the compressed air source 37 reaches the opening 33 of the nozzle 32.
- the compressed air pulse is set such that the cotton end E is separated directly behind the clamping point K that means that the dividing line is exactly on the line of the openings 33.
- the cotton end E thus separated is suctioned off and discharged.
- the valve 20 is again via the control unit is controlled and the cylinder 14 is pressurized with compressed air via the line 21.
- the piston rod of the cylinder 14 is retracted and the wall element 11 is pivoted back into the position shown in FIG. 2
