Definitions
- the invention relates to a device for feeding and compacting a cotton web for a subsequent winding device with at least three calender rolls arranged one behind the other and approximately in a row, which in their working position are coupled to a drive device.
- the calender rolls In their working position, the calender rolls each form a clamping point with the adjacent rolls, via which the cotton web is guided in a serpentine line around the calender rolls.
- the calender rolls serve to press or compress the cotton web in order to be able to unwind the subsequently formed cotton lap without mutual felting of the cotton web.
- the cotton web In order to obtain a good pressure, the cotton web should be compacted at least twice before the roll is formed.
- a small delay between the individual calender rolls can also be provided.
- the object of the invention is therefore to propose a device which enables a cotton web to be easily and easily inserted between calender rolls which are arranged in a row.
- the object of the invention is achieved in that at least one of the calender rolls can be moved out of the row or out of its working position by means of a device.
- the term “row” is not restricted to one arrangement, the calender rolls arranged one behind the other being in a horizontal plane. Rather, the term “row” can also apply to such designs, wherein in the working position the axes of rotation of the calender rolls arranged one behind the other are not in one Level. This would be, for example, an arrangement as shown in Fig. 1 of EP-B1-141 258. Although all the calender rolls are outside their actual working position, they are still arranged in a row.
- the term "out of line” can be defined in such a way that the calender roller is outside the row when it has been moved out of the transport area of the cotton web.
- the term "row” could include everything that lies within an envelope, that can be wrapped around the calender rolls when they are in the working position.
- swiveling out a calender roll from a row involves transferring it to a position in which the cotton web can be easily carried out between three successive calender rolls by hand.
- the term “displaceable from the row” can preferably mean that the calender roll is displaced from its working position by at least the measure of its diameter.
- the calender roll displaceable out of the row be assigned two adjacent calender rolls in its working position, of which at least one calender roll is arranged displaceably within its row from its working position.
- the subsequent quay roll can also be adjusted such that the cotton web can also be inserted between this calender roll and another subsequent calender roll without any problems. This means that it is not necessary for the machine to be operated in stop / go mode in order to run the cotton web between the calender rolls. This would also be far too dangerous for the operator.
- At least four calender rolls are arranged one behind the other, the first and fourth calender rolls being mounted in a stationary and rotatable manner, as seen in the transport direction of the cotton web, the third calender roll being in its working position within the row and the second calendering roll being in its working position is shiftable out of line.
- This device enables problem-free threading, with at least three clamping points for the cotton web being present in order to enable sufficient compression of the cotton web.
- the calender rolls are preferably provided with drive elements which are in engagement with one another in the working position of the calender rolls. It is proposed that at least one of the calender rolls is connected to a drive unit, wherein the drive elements can be designed as toothed wheels which mesh with one another in the working position of the calender rolls *.
- This device enables simple power transmission, which can be coupled or released by pivoting the calender roll, which is adjustable from the row.
- the adjustable calender rolls are preferably rotatably mounted on a respective pivoted lever.
- At least one actuator by means of which the swiveling movement is carried out, acts on its swiveling lever.
- the actuator can be a cylinder that e.g. can be controlled via a control device.
- the device for moving the calender roll out of its working position is arranged or designed within the row such that this calender roll automatically, e.g. via its gravity, over a range predetermined by a limiting member, away from the subsequent calender roll as soon as its drive coupling with the preceding calender roll, which can be moved out of the row, is released.
- This ensures a simple design without additional actuators for the calender roll which can be pivoted within the row.
- a restriction member e.g. a stop may be provided on which the lever strikes after a predetermined pivoting movement.
- the lever could also be designed with two arms, the calender roller being supported on one arm and the other arm cooperating with a stop in order to limit the pivoting.
- Fig. 1 is a schematic representation of a winding device with a feed device by means of calender rolls.
- Fig. 2 is an enlarged view of the feed device with swiveling calender rolls claimed according to the invention.
- Fig. 3 is a schematic representation of a further embodiment of a feed device to a winding device with swing-out calender rolls.
- Fig. 4 shows an embodiment of FIG. 3 with the calender rollers swung out.
- FIG. 1 and 2 show, in a purely schematic representation, a winding device 10 for producing a wadding roll 12.
- a winding device 10 for producing a wadding roll 12.
- the winding device 10 can be used, for example, in a combing mill to receive a fleece that runs out of a drafting system, in particular fed via calender rolls and / or the like, the generated winding being subsequently presented to a combing machine.
- the following only refers to cotton wool in connection with the supplied fiber material, which should not be understood in a restrictive sense.
- the winding device 10 is supplied with cotton wool 14 via an assigned calendering unit 16, which in the present case comprises four calender rolls 16a, 16b, 16c and 16d.
- the wadding 14 is wound onto a sleeve-like core H, which in the illustrated embodiment is rotatably mounted about a fixed axis A during the winding process.
- This core H is driven by a revolving, endless belt 18, by means of which a horizontally extending loop 20 is formed between two deflection rollers R1 and R2, in which the core H is received during the winding process.
- the sleeve-like H and thus the wadding 12 formed on this is driven by the belt 18 in a clockwise direction, as indicated by the arrow F.
- the loop 20 shown with solid lines is shown in the phase at the beginning of the winding process.
- the belt 18 is guided over wide deflection rollers R3 and R5 and the tensioning roller R4 adjustable along a linear guide in such a way that it is tensioned over the tensioning roller R4 in a plane which runs in the vertical direction and is thus perpendicular to the generally horizontally extending loop 20.
- the belt 18 can be tensioned via the tensioning roller R4, for example, in a plane that runs generally in the horizontal direction and thus in a parallel loop 20.
- the lower deflection roller R1 offset to the left can be adjusted between a working position provided for forming the loop 20, shown in FIGS. 1 and 2, and an eject position into which this lower deflection roller R1 can be transferred to eject the finished wadding roll 12 by tightening the belt 18 while lifting the loop 20.
- this lower deflection roller R1 which is adjustable between a working position and an ejection position, can be pivoted about a defined, fixed axis B via a pivot lever 24, which in the exemplary embodiment shown coincides with the axis of the lower left deflection roller R5.
- the lower deflection roller R1 can thus be pivoted downward about the axis B via the pivoting lever 24 so that when it is transferred to the ejection position (not shown) and the belt 18 is tightened, a rolling surface that slopes downward with respect to the horizontal is generated for the finished cotton wadding 12 to be ejected .
- the wadding roll 12 can be transferred into an area below the calendering unit 16 via the rolling surface generated in this way. There, the finished wadding roll can be placed, for example, in a roll holder, which can be assigned to a transport device.
- the deflection roller R1 After insertion of the next sleeve-like core H, the deflection roller R1 is brought back into the working position shown by pivoting the pivot lever 24 back.
- the deflection rollers R1, R2, R3 and R5 and the tensioning roller R4 have essentially the same diameter as the respective sleeve-like core H.
- the axes of the rollers and of the sleeve-like core H inserted into the loop 20 are mutually the parallel.
- the belt 18 is driven by the deflection roller R5.
- the tensioning roller R4 assumes an upper end position, from which it is transferred to a lower end position during the winding process, but in which it is offset somewhat upwards compared to the deflection roller R3.
- This deflecting roller R3, which is offset downward and to the right relative to the tensioning roller R4, is expediently arranged such that the belt 18 always surrounds the tensioning roller R4 regardless of its position with a wrap angle of 180 °.
- the supplied cotton wool 14 with the belt 18 is guided through the gap formed between the lower, pivotable deflection roller R1 and the rear calender roller 16d to the gap formed between the core H and the belt 18.
- the rear calender roll 16d arranged in the opening area of the loop 20 lies at least substantially also within this horizontal loop 20, which is formed by forming a lower and an upper loop section 20a or 20b, and between the adjacent lower deflection roller R1 and the upper deflection roller R2, which is offset somewhat to the right .
- the rear calender roller 16a which is arranged between the two superposed deflection rollers R1, R2 forming the loop 20 and is opposite the lower deflection roller R1, is rotatably mounted about a fixed axis C in the present exemplary embodiment.
- the front calender roll 16a is also rotatably mounted about a fixed axis D.
- the two calender rolls 16b and 16c arranged between the front calender roll 16a and the rear calender roll 16d can be pivoted out of their working position into the positions shown in dashed lines in FIG.
- the calender roller 16c adjacent to the rear calender roller 16d can be pivoted in with force introduction, while the calender roller 16b adjacent to the front calender roller 16a can be pivoted without such force introduction.
- the force introduced via the calender roll 16c is laterally distributed on the one hand to the rear calender roll 16d and on the other hand via the calender roll 16b to the front calender roll 16a.
- the further calender rolls 16a, 16b and 16c with their axes lie in a common plane G (see FIG. 2), the one with plane I containing the axes of the rear calender roll 16d and the adjacent calender roll 16c obtuse angle et forms.
- the plane G containing the axes of the further calender rollers 16a, 16b, 16c is inclined downwards with respect to the horizontal.
- the axes of the rear calender roll 16d and the adjacent calender roll 16c also include Ending plane I is again inclined downwards from the calender roll 16c with respect to the horizontal.
- the diameter of the rear calender roller 16d adjoining the belt 18 is smaller than that of the further calender rollers 16a, 16b and 16c.
- the calender roller 16b is pivoted upward by the pivoting lever 26 into the position shown in broken lines in FIG. 2 in order to facilitate the insertion of the cotton wool 14 when it is attached.
- the calender roller 16c which can be pivoted by means of the pivoting lever 28, serves to introduce the force into the calendering unit 16, the force Fk generated in this way being distributed laterally via the calender roller 16b to the front calender roller 16a and to the rear calender roller 16d which is directly adjacent to the belt 18.
- the calendered fleece is thus transferred directly to the belt 18 via this rear calender roll 16d.
- the wadding 14 is guided in the area in the running direction of the wadding web in front of the calender 16 by a riser 30.
- a sleeve magazine (not shown here) is preferably provided, which extends generally in the vertical direction and is arranged in an area below the calendering unit 16, wherein a core H to be reloaded in each case is expediently fed into the in FIG Figure 1 shown winding position can be transferred.
- FIG. 3 and 4 show a further exemplary embodiment, a row R of calender rolls K1 to K4 being provided in order to feed a cotton web W to a winding device 40.
- This winding device 40 supplied and calendered cotton web W is wound onto a sleeve 42 which rests on two winding rollers 43 and 44.
- the winding rollers 43 and 44 are rotatably supported and are set in rotation during the winding process by means of a drive (not shown).
- a drive not shown.
- To attach the new cotton end to the sleeve 42 this is with not shown on Provide their circumference distributed holes through which the cotton web is sucked onto the sleeve surface, since a vacuum is applied within the sleeve 42.
- Such an embodiment has been known for a long time, which will not be discussed in more detail here.
- the calender rolls K1 to K 4 are each rotatably connected to a gear Z1 to Z4, which are indicated schematically.
- the gears Z1 to Z4 are each coaxial and on one side of the calender rolls K1 to K4. 3, all the gears Z1 to Z4 are in engagement with one another.
- a drive pulley 46 is additionally attached in a rotationally fixed manner, which is driven by a drive element 48, e.g. a belt is connected to a drive pulley 47.
- the drive power is transmitted from the drive sheath 47, which is driven by a transmission (not shown in more detail), via the drive sheave 46 and via the respective toothed wheels Z1 to Z4 to the calender roll K4.
- the wadding W as shown, is guided and compressed in a serpentine line between the clamping points of the individual calender rolls K1 to K4.
- the drive of the calender rolls K1 to K4 is stopped, while the drive of the winding rolls 43 and 44 is still maintained.
- the cotton web W is torn off in the region of the guide 50 between the calender roller K4 and the winding roller 43.
- the cotton roll formed is ejected to the rear by an ejection device (not shown in more detail) and transferred to subsequent machine processing machines, for example combing machines, by means of further transport devices.
- the length of the rolled-up cotton web can be determined indirectly, for example, by sensing the rotation of one of the gear wheels via a sensor.
- the size ratios of the winding device to the calender rolls K1 to K4 shown in the example do not correspond to the actual size ratios in practice. This means that the winding device 40 is only indicated schematically.
- the calender roll K3 is rotatably mounted about a fixed axis of rotation 53 via a two-armed lever 52.
- the lever 52 supports, on the one hand, the calender roller K3 via the axis of rotation 55 and, on the other hand, a stop bolt 56 on the opposite arm.
- the bolt 56 hits a fixed stop 58 during the pivoting movement in the clockwise direction of the lever 52.
- the calender roll K2 is rotatably mounted on an axis 59 in a lever 60.
- the lever 60 is connected via an axis of rotation 61 to a further lever 63 which is pivotally mounted about the axis of rotation 64.
- a cylinder Z engages lever 63 via a further axis of rotation 66.
- the cylinder Z is articulated on the machine frame 1 via an axis of rotation 68 and is pressurized with compressed air via a control valve 70 via the lines 71 and 72.
- the valve 70 is controlled via a line 73 from a control unit 75.
- a lever 60 with associated lever 63 and cylinder Z is provided at both ends of the calender roll K2.
- the calender roll K3 is provided at both ends with a lever 52, which enables it to be pivoted about the axis of rotation 53.
- a scanner element 77 is attached to the lever 63 and is scanned by the sensors 78 and 79 fixedly arranged on the machine frame 1.
- the sensors 78 and 79 are connected to the control unit 75 via the line 80 or 81 and serve to monitor the position of the lever 63.
- the position of the calender roller K2 is also monitored by monitoring the position of the lever 63. It would also be possible to monitor the displacement movement of the piston rod ZK in order to obtain a conclusion about the position of the calender roller K2. If there is a change in the material template or if a malfunction needs to be remedied, it is necessary to insert a new cotton end between the calender rollers K1 to K4.
- the lever 63 is pivoted into the position shown in FIG. 4 by actuating the cylinder Z, which is controlled via the control unit 75 and via the valve 70.
- the pivoting of the calender roller K2 via the lever 60 about the axis of rotation 61 is limited in the clockwise direction by the stop 65 attached to the lever 63.
- the gears Z1 and Z2, or Z2 and Z3 also come out of engagement.
- the calender roller K3 Since the center of gravity line S of the calender roller K3 is displaced by the distance a from the axis of rotation 53 in the direction of the winding device 40, the calender roller K3 carries out a pivoting movement due to its gravity in the direction of the first calender roller K1 until the bolt 56 rests on the stop 58. In this position, the gears Z3 and Z4 are disengaged and there is a sufficiently large gap for threading the wadding web W to be fed between the quanding rollers K3 and K4. To reach the end position, the piston rod ZK of the cylinder Z is extended until the sensor 79 has recognized the scanning element 77 on the lever 63.
- the new wadding end of the wadding W which is already on a guide plate 54, can now be conveniently placed by hand between the swung out calender roll K2 and the calender roll K1 over the calender roll K3.
- the new cotton end is then passed between the open nip of the calender rolls K4 and K3 and placed on the guide 50.
- the calender roller K2 becomes in line again R swung in.
- the gear Z2 engages with the gears Z1 and Z3.
- the toothed wheel Z1 or the calender roller K1 is now rotated. This also drives the gears Z2 to Z4 or the calender rolls K2 to K4. The cotton end is hereby transferred into the area of the sleeve 42, so that the winding process can be started again.
- the arrangement shown ensures simple and problem-free threading of the cotton web between the quay rollers without any aids.
