Definitions
- the invention relates to a textile processing machine according to the preamble of claim 1.
- combing preparation machines for example combing preparation machines, combing machines and draw frames
- combing preparation machines for example, slivers drawn from cans are presented, which are drawn in drafting units and fiber webs are formed.
- Several such non-woven fabrics are placed one on top of the other on a feed table and transferred to a subsequent winding device to form a lap of cotton.
- the textile material is processed in the area of the drafting rollers, the fiber material being distorted by different speeds of the drafting rollers. During this stretching process, fibers can detach from the textile material due to the movement of the working elements (e.g. drafting rollers, pressure rollers) and enter the room as a so-called fiber fly.
- working elements e.g. drafting rollers, pressure rollers
- the drafting system is usually accommodated in a space delimited by walls, with corresponding openings being provided in order to ensure the entry or exit of the textile material into and from the drafting system area. Openings must also be provided in these walls so that the drive can be transferred to the drafting rollers from corresponding drive elements (for example shafts). These openings must be dimensioned sufficiently to allow the center distances of the drafting rollers to be adjusted. This means that the space of the drafting rollers with the pressure rollers can be changed due to the required openings and the necessary additions.
- Accessibility is not absolutely sealed off from the other interconnected areas of the machine, which also contains the drive elements and partially the bearings of the drive elements.
- the result of this is that the creation of a vacuum in the work area also creates a vacuum in the other areas or rooms where drive elements and bearings are located, especially since both rooms are located directly next to or adjoin one another.
- contaminants which are found, for example, as a fiber fly in the area surrounding the machine, also reach the formwork area via cracks and other openings, or into the rooms in which the drive elements and, in part, the bearings are located.
- vacuum cleaner effect This effect, which leads to the contamination of these drive elements and bearing points, is generally referred to as the "vacuum cleaner effect". This requires a considerable amount of maintenance work and increased attention by the operators.
- a round comb for combing out a fiber beard clamped by a pair of pliers is mounted in a combing suction shaft.
- This combing chute is surrounded by a room that is delimited by walls. In this room, in which the bearing elements and drive elements are located, contamination can also occur due to the negative pressure generated via the comb suction duct collect from dust and fiber fly. Since these areas are also difficult to access, maintenance of these rooms is extremely difficult and time-consuming.
- the object of the invention is to design the textile material processing machine in such a way that the maintenance outlay for cleaning is also reduced for the space delimited by walls for the drive elements or bearings located in this space.
- This object is achieved in that further means are provided for supplying air to the space of the drive elements mentioned, or their bearings at a pressure which is higher than the air pressure in the vicinity of the machine. This prevents the fiber fly and dust in the vicinity of the machine from being drawn into the space of the drive elements or bearings.
- This proposed combination avoids settling and contamination with fiber fly and dust by applying a negative pressure in the area of the working elements and by applying an excess pressure in the area of the drive elements and bearings. As a result, the time required for manual maintenance can be reduced considerably.
- working elements essentially refers to the tools that act directly on the fibers and that change the fiber structure of the textile material presented.
- drive elements essentially includes gears, pulleys, belts, chains, shafts, etc.
- bearings essentially refers to shaft bearings or the bearing of axes of the drive elements or of the working elements.
- openings are provided between the spaces of the working elements and the space of the drive elements, through which openings, for example, drive shafts can protrude.
- the drive shafts can simultaneously represent the drive axes of the drafting rollers.
- the openings described are at least partially covered with flexible cover elements. This prevents unnecessary and undesired air circulation between these two rooms.
- cover elements can advantageously be formed from bristles fastened on one side to the wall in the region of the respective opening.
- cover elements from sealing lips, for example rubber elements, fastened on one side to the wall in the region of the respective opening.
- the means for generating an overpressure is advantageously a blower.
- the means mentioned contain a device for regulating the humidity of the air supplied to the space mentioned.
- the means contain a device for regulating the temperature of the air supplied to the space mentioned.
- the fan is preceded by a corresponding filter element that keeps the air sucked in by the fan free of dust.
- the means can advantageously include air conditioning.
- the feed means can consist of a forceps unit of a combing machine, which for combing out presents a fiber beard clamped by the forceps unit to a circular comb, the circular comb being surrounded by a combing suction duct which is surrounded by a space bounded by walls.
- the suction side of the blower is advantageously connected to the comb suction duct.
- FIG. 1 shows a schematic vertical section through a combing machine in the region of a combing head
- FIG. 2 shows a schematic horizontal section along the line A-A in FIG. 1, with further elements drawn in block diagram form,
- FIG. 3 shows a schematic top view of a drafting unit in the area of the infeed table of a combing preparation machine for winding formation
- FIG. 4 is a schematic side view of FIG. 3,
- FIG. 5 is an enlarged partial view according to FIG. 4 in the transition area of the drive shafts from the room with positive pressure into the room with negative pressure, and
- FIG. 6 is a partial plan view according to FIG. 5.
- a combing head of a combing machine contains an oscillating pliers 1 in which an intermittently rotatable feed cylinder 2 is mounted.
- a cotton wool to be combed is fed to the feed cylinder 2 from a cotton wool roll 3, which is carried on two rotatable winding rolls 4 and 5.
- a fiber beard from the cotton wool fed between the clamping plates of the pliers clamped and is combed out by a rotating circular comb 6, with which a likewise rotating circular comb brush 7 interacts.
- the pliers 1 are then moved into their illustrated advanced end position and opened, and the fiber beard is torn off the cotton wool by a tear-off unit with pairs of rollers 8 and 9 and combined with the previously formed vias of combed material.
- the combed single headband then runs over a fleece guide plate 10 (also called fleece bowl) to pairs of take-off rolls 11 and 12 and is delivered by these in strip or fleece form to an outlet table 13, which is assigned to all combing heads of the machine together.
- a fleece guide plate 10 also called fleece bowl
- the circular comb 6 is surrounded by a comb suction duct, which has a front wall 14, two side walls 15 (FIG. 2) and 16 and a rear wall 17.
- the shaft 14, 15, 16, 17 opens at the bottom into a suction channel 18, which is in turn assigned to all combing heads of the combing machine.
- combs short fibers
- impurities are pneumatically discharged, which are removed from the round beards 6 and from a non-illustrated comb comb.
- the rotating circular comb brush 7 is also arranged in the shaft 14, 15, 16, 17.
- the combing suction shaft 14, 15, 16, 17 is surrounded by a space which is laterally delimited by walls 19, 20 21 and 22, namely by a front casing 19, a rear casing 20 and two side plates 21 and 22.
- the shafts of the drivable rollers of the combing head are mounted.
- Further combing heads can be connected to each of the side plates 21 and 22, which are essentially the same as those described above.
- Combing machines of the type described above are generally known.
- a problem in the known combing machines is the fibers and impurities which are found in accumulate the space surrounding the combing suction shaft 14, 15, 16, 17 These fibers and contaminants come in particular from the wadding that is moved from the wadding roll 3 to the feed cylinder 2, and from the wadding that from the tear-off unit 8, 9 via the wadding guide plate 10 and is moved by the take-off rollers 11, 12.
- the cleaning of the walls of the above-mentioned room, in particular in front of and to the side of the combing chute 14, 15, 16, 17, is tedious and time-consuming because these walls are difficult to access
- means are provided for supplying air to said space at a pressure which is higher than the air pressure in the vicinity of the comb machine.
- These means contain an air supply line 23, which starts from a blower 24 and leads to an opening opening into the space mentioned, for example, as shown schematically to an opening 25 in the front casing 19. There is therefore an overpressure in the space mentioned, with which air flows from the space out into the environment.
- These air currents prevent fibers and contaminants, which come loose from the cotton wool coming into the feed cylinder 2 or from the fleece between the tear-off unit 8, 9 and the take-off rollers 11, 12, from entering the space mentioned
- a device 26 is preferably arranged on the suction side of the blower 24, which conditions the sucked-in air, that is to say regulates the humidity of the air, or climates it, that is to say that regulates the humidity and the temperature of the air and that Air cleans.
- the device 26 can be an air conditioning system. If so, the air that is blown from the space surrounding the combing suction shaft 14, 15, 16, 17 upwards against the cotton wool coming into the feed cylinder 2 and against the fleece between the tear-off unit 8, 9 and the take-off rollers 11, 12 is conditioned or air-conditioned the requirements for the usual air conditioning of the combing machine environment can be reduced.
- the device 26 can of course also be arranged on the pressure side in the line 23 instead of on the suction side of the fan 24.
- the air sucked in by the fan 24 can be drawn from the environment via an inlet line 27.
- the blower 24 can also be the blower that generates the negative pressure for sucking up the noils and contaminants from the combing suction duct 14, 15, 16, 17, that is to say the suction side of the blower 24 can, if appropriate via the device 26 and also via a line 28 and a conventional comb separator 29 can be connected to the suction channel 18.
- FIG. 3 shows an infeed table 35 with drafting units 36 and 37 connected in series. Fibrous tapes F are fed to the drafting units next to one another via a feed device (not shown in more detail).
- the drafting units consist of driven lower rollers W1 - W4, to which pressure rollers D1 - D4 are assigned. Since the two drafting units 36 and 37 shown are identical, the same reference numerals have also been used.
- the fiber slivers warped in the drafting unit 36 arrive as fiber fleece V1 and via the pair of rollers 40, 41 on the guide surface 44 of the inlet table 35.
- the lower roller 41 is driven.
- the fiber tapes F fed to the subsequent drafting unit 37 are, after the drawing process, as nonwoven fabric V2 also placed on the guide surface 44 or on the nonwoven fabric V1 supplied by the first drafting unit 36 and doubled with it.
- the fiber fleece V thus doubled is transferred to a subsequent winding device, not shown, in which a cotton roll is formed.
- a complete representation of the machine described can be found, for example, in published EP-A1 679 741.
- the nonwoven fabric V2 is transferred via the roller pairs 42 and 43 to the guide surface 44 or the nonwoven fabric V1.
- the roller 43 is driven.
- 3 and 4 schematically show that air is drawn off in the rooms 48 and 49 via the lines 60, 61 and 62 and a suction fan 64 and a negative pressure is built up.
- 4 schematically shows that the lines 60 and 61 open into the area of a suction slot 66, which is provided above the pressure rollers. This is intended to specifically remove the fiber fly or dust accumulating in these rooms 48 and 49.
- the formwork of the drafting unit is designed in two parts, in particular for maintenance work and for eliminating malfunctions, the upper hood being designed to be pivotable upwards via a hinge indicated in FIG. 5.
- rubber seals (not shown) which exert a sealing effect when the divided walls lie one on top of the other.
- a fan wheel 75 which blows air from the surroundings of the machine into the space 78 surrounded by walls via a sieve filter 76.
- the space 78 is surrounded by the walls 79 and 80 as well as the lower wall 81 and the guide surface 44.
- the rollers W1-W4 are driven by the gears 70 and 71 via the drive shafts A1-A4, which project through openings 58 in the wall 51 into the spaces 48 and 49, respectively.
- the drive shafts A1-A4 can (not shown) be designed as cardan shafts, which allow an adjustment of the center distances of the rollers W1-W4.
- the opening 58 through which the drive shafts A1-A4 protrude, is shown in detail and enlarged in FIG. 5.
- the opening 58 is located in the fixed part 51 'of the wall 51 and is dimensioned such that the distance between the rollers W1-W4 can be adjusted.
- a row of bristles B1 and B2 is fastened in the upper and lower edge region of the opening 58, the bristles of which protrude into the region of the opening 58 and partially overlap in the central region. Since the bristles of the bristle rows B1 and B2 are flexible, they can nestle against them in the area of the drive shafts A1 - A4 and open the passage for the shafts.
- the space 90 and 91 in which the drive elements are located and which is under positive pressure, is partially sealed off from the spaces 48 and 49, which are under negative pressure, with the possibility of adjusting the center distances of the rollers W1 - W4 is guaranteed.
- a similar seal can also be made in the area of the passage for the drive shafts A5 for the respective roller 41 or 43.
- the rollers W1-W4 are mounted on the opposite sides of the drive shafts A1-A4 in schematically illustrated bearings L.
- the respective gears 70, 71 are driven via a schematically illustrated belt drive 68 and via the respective transverse shaft 72 or 73.
- the drive is also via a schematically illustrated belt drive for the drive shafts A5 of the rollers 41 and 43 decreased.
- the belt drive 68 which is driven by a drive motor, not shown, is also housed in the space 92, which is under an overpressure.
- the other drive elements of the winding unit can also be arranged in rooms which are also under overpressure.
- the formwork and the walls are not designed so that the rooms are completely sealed off from the surroundings of the machine. Rather, there are still small cracks and openings in some places, through which air in particular can escape from the rooms with excess pressure. However, this has a positive aspect in that deposits on the machine can also be prevented by the escaping air.
- the blower 75 can also be associated with devices which condition or air-condition the suction air accordingly.
- the application of the invention is not limited to the machine types shown, but can be used in all areas of textile machine construction where on the one hand, processing of textile material is carried out and, on the other hand, drive units for their working elements and storage points are available.
