Definitions

  • the invention relates to a combing machine with a plurality of combing heads, wherein each combing head contains a rear carrying device with at least one first drivable winding roller for a first cotton roll and a front carrying device with at least one second drivable winding roll for a second cotton roll and each combing head has a transport device for setting down of cotton wraps is assigned to the front support device.
  • a comb chair with a single combing head of the specified type is described in DE-B-24 34 898.
  • the transport device is actuated so that it places a new wad of cotton on the front carrying device (or on the cotton wad that is now running from the second cotton wad). No precautions have been taken to prevent thickened areas or areas of reduced thickness of the superimposed cotton bands from appearing between the end of the cotton tape from the first cotton roll and the beginning of the cotton tape from the new cotton roll.
  • the object of the invention is to design the combing machine specified at the outset with a plurality of combing heads in such a way that it is possible to carry out a winding change in such a way, and at the same time also with some or all of the combing heads of the machine, that between the end of a cotton band that starts from the first Cotton swab has expired, and the beginning of a cotton tape on a new cotton roll that is deposited by the transport device on the front support device, thickening and places with reduced thickness are automatically avoided.
  • each combing head contains a device for severing of the cotton tape which has been unwound from the first cotton roll and runs to the front carrying device, in order to form a defined end of this cotton tape at a predetermined location, and that a control device, which is assigned to at least some of the combing heads, is provided for controlling the devices for cutting through and the transport devices of these combing heads, that the transportation facilities are new Place the cotton wrap on the front support devices at such a time that the beginnings of the cotton strips on these new cotton rolls are aligned with the ends of the cotton tape formed by the severing devices and leading to the front support devices.
  • the control device can expediently also control devices for removing empty or almost empty winding sleeves from the rear carrying devices and devices for rolling the second wadding rolls backwards from the front onto the rear carrying devices.
  • the essential combing tools of the combing head shown schematically in FIG. 1 are a rotatable circular comb 1, a fixed comb 2, two tear-off cylinders 3 and a pair of pliers with a pair of lower pliers 4 and an upper plier 5 which can be pivoted with respect to the lower pliers 5 stored.
  • the feed cylinder 6 is supplied with two cotton bands I and II lying parallel to one another.
  • the cotton tape I is unwound from a first cotton roll 7, which is carried on a rear support device.
  • the rear support device consists of two parallel winding rollers 8 and 9, at least one of which can be driven.
  • the cotton tape II is unwound from a second cotton roll 10, which on a front support device is worn.
  • the front support device again consists of two winding rollers 11 and 12, which are parallel to each other and to the winding rollers 8 and 9. At least one of the winding rollers 11 and 12 can be driven.
  • the first cotton band I runs over the front carrier device, ie over the winding rollers 11 and 12, and the second cotton roll 10 lies over the front carrier device on the first cotton band I.
  • the combing machine contains several, e.g. eight comb heads of the type described, arranged in a row. If in one of the combing heads of the machine the cotton tape I is at least almost completely unwound from the first wadding roll 7, then a winding change is carried out automatically and without switching off the combing machine, simultaneously with all combing heads of the machine or at least with one group of combing heads, e.g. with four combing heads.
  • each combing head contains a detector (not shown) which e.g. 2 determines the time at which the end E of the first cotton tape I appears on the winding tube of the first cotton roll 7.
  • This detector can, for example, be a photocell that detects the difference in brightness between the lighter cotton tape and the darker winding tube of the cotton roll 7.
  • the detector emits a signal which starts a program control device (not shown) which then simultaneously effects the operations described below in all combing heads of the machine or at least in one group of the combing heads.
  • a device for removing the empty or almost empty winding tube of the first cotton roll 7 from the rear support device 8, 9 is actuated.
  • This facility contains, for example Device for moving the rear winding roller 9 into the position indicated with a broken line in FIG. 2, for example a device 13 (FIG. 1) for pivoting arms 14 carrying the rear winding roller 9.
  • This displacement increases the distance between the winding rollers 8 and 9 enlarged to such an extent that the empty or almost empty winding tube falls down between the two winding rollers.
  • a guide 15 is expediently arranged under the winding rollers 8 and 9, on which the winding tube then rolls backwards.
  • the cotton residue remaining on the winding tube - which will of course have slightly different lengths in the different combing heads - unwinds and remains on the guide 15.
  • the empty winding tube rolls onto a collecting tray 16, as shown in FIG. 3.
  • the device for severing can contain, for example, means for pressing the cotton tape I against the driven winding roller 8 so that it moves the cotton tape I further, and means for holding the cotton tape I directly behind the winding roller 8 so that the cotton tape tears here.
  • the means for pressing the cotton tape I against the winding roller 8 can include means for moving the winding roller 9 against the winding roller 8 as shown in FIG. 4, for example the already mentioned device 13 (FIG.
  • the swivel arms 14 can at the same time carry a clamp rail 17 which is connected to a fixed, For example, pliers rail 18 attached to the guide 15 cooperate in order to clamp the cotton tape I behind the winding roller 8.
  • the cotton tape I moved on by the winding rollers 8 and 9 then tears between them and the tong rails 17, 18, and a new, defined end E.1 of the cotton tape I is created.
  • a device for removing the separated rear end portion of the cotton tape I from the guide 15 is operated.
  • a suction channel 19 opens into the guide 15 from below, in which a negative pressure is generated, as indicated in FIG. 5.
  • a device is actuated which brings the second wad of cotton 10 backwards from the front carrying device 11, 12 onto the rear carrying device 8, 9.
  • This device contains, for example, a plunger 20 which pushes the cotton roll 10 backwards so that it rolls on the cotton tape I (supported by a guide 21) into the position shown in FIG. 6.
  • Each combing head is assigned a transport device for depositing new cotton bobbins on the front carrying device 11, 12. Of this transport device, only one support arm 22 with a pin 23 is shown in FIGS. 1 and 7.
  • the transport device 22, 23 is now actuated in order to place a new cotton roll 24 on the cotton bands I and II, which run over the winding rollers 11 and 12 of the front carrying device.
  • the start A of the cotton tape on the new cotton roll 24 is positioned on the circumference of this roll so that this start A at the time of Placing the winding 24 on the front support device has the same distance from the winding roller 12 as the end E.1 of the first cotton tape I.
  • FIG. 8 shows a state as it can occur after the start A and the end E.1 have left the winding roller 11.
  • the start A may be attached to the circumference of the new roll 24. Therefore, a detaching device for detaching the start A from the circumference of the roll 24 is now actuated.
  • the detaching device is, for example, a suction nozzle 25, which is moved towards the circumference of the cotton roll 24 in order to detach the start A.
  • the suction nozzle 25 is then withdrawn again and the negative pressure is switched off, so that the start A, as shown in FIG. 9, lies on the cotton tape II coming from the cotton roll 10.
  • a suction roller or a mechanical element could of course also be used in order to detach the beginning A from the circumference of the new wadding roll 24 and to place it on the wadding band II.
  • the start A of the cotton tape from the new cotton roll 24 lying on the cotton tape II then runs together with the cotton tape II through a pair of press rollers 26 which presses the start A onto the tape II.
