Definitions
- the invention relates to a winding device for producing a wadding roll, in which the wadding is wound onto a core driven by a revolving, endless belt, which core can be used for this purpose in a loop of the belt that can be tensioned by a tensioning device and is made larger between two deflecting rollers and increases with increasing wadding roll , wherein at least one of the deflecting rollers is adjustable between a working position provided to form the loop and an ejection position, into which this deflecting roller can be transferred in order to eject the lap wrap by tightening the belt while lifting the loop.
- the aim of the invention is to provide an improved winding device of the type mentioned at the outset which, with a simple and compact structure, allows the winding output to be as problem-free and rapid as possible, and thus in particular the fastest possible replacement of the finished wadding roll with a new core enables.
- the object is achieved according to the invention in that, in addition to the tensioning device, at least one compensating element is provided, by which at least the majority of sections of the adjustable deflection pulley is transferred from the working position to the ejection position and the tensioning of the belt is lifted while lifting the loop occurring belt length displacements is compensated for, while during the winding process due to the loop widening with increasing wadding wrap, belt length displacements occurring in sections are at least predominantly compensated for by the tensioning device.
- the tensioning device After the tensioning device is at least predominantly only intended to compensate for belt length changes occurring during the winding process as a result of the loop becoming larger as the wadding lap becomes larger, it can be dimensioned accordingly without any restrictions in terms of the fastest possible winding output having to be accepted. Rather, by appropriate design of the additionally provided compensating element, this ejection speed can be increased in the desired manner without any problems and irrespective of the respective dimensioning of the tensioning device, which in particular also enables a faster exchange of the finished cotton lap for a new core, for example formed by a sleeve or the like is.
- the additional compensation element can thus be designed in particular for rapid compensation of generally small belt length displacements, while the tensioning device can be provided for the slower compensation of larger belt length displacements with larger forces to be applied.
- both a relatively rapid opening of the belt loop and an accelerated winding output are possible regardless of the respective tensioning device.
- This advantage of a largely independent compensation of the tensioning device during the opening of the belt loop and the ejection of the cotton roll comes into play in particular in a preferred embodiment in practice, in which the core can be rotated about a fixed axis during the winding process and the belt tension at least during this winding process is essentially predetermined by the clamping device.
- the forces to be applied during the winding process can in particular also be greater than the weight of the wadding roll.
- the additional compensating element can be designed independently of the tensioning device to be dimensioned correspondingly large, rapid opening of the belt loop and rapid winding output are still possible.
- the compensating element can, for example, be subjected to special loads or can only be under the influence of gravity. In the former case, the compensating element for generating the respective compensating forces can preferably be acted upon independently of the tensioning device.
- the deflection roller which is adjustable between a working position and an ejection position, is adjustable independently of the tensioning device, which is possible in particular through a separate drive.
- the compensating element preferably also compensates for at least the majority of the belt length changes occurring in sections during the return of the adjustable deflection roller into the working position and / or during the new formation of the loop, which preferably takes place with the introduction of a new core. In this way, the entire process of exchanging a wadding roll for a new core can be accelerated regardless of the particular dimensioning of the tensioning device.
- the loop can, for example, extend downwards in the vertical direction. An at least essentially horizontal ejection of the wadding roll is possible.
- the loop can also extend in the horizontal direction or be inclined to the vertical.
- deflection roller which is adjustable between a working position and an ejection position, can be pivoted about a defined axis by means of a swivel lever.
- a particularly compact arrangement which in particular also requires only a minimum of space when the pivoting lever is pivoted out, is achieved in that the deflecting roller which can be pivoted between a working position and an ejected position can be pivoted together with a further deflecting roller and the two deflecting rollers are arranged at a fixed distance from one another on the pivoting lever .
- a compensating element can thus be formed, for example, by the further deflection roller arranged on the swivel lever.
- the two deflecting rollers are preferably pivotable so that with the transfer of the adjustable deflecting roller into the ejecting position and the tightening of the belt, a rolling surface that preferably descends from the horizontal downward is generated for the cotton wadding to be ejected and the further deflecting roller preferably in the course of the pivoting movement of the belt is released.
- the defined pivot axis can, for example, be arranged close to and preferably below the region of the initially fixed axis of rotation of the core. In principle, however, it is also possible for the defined pivot axis to be arranged in the region of the initially fixed axis of rotation of the core or to coincide therewith.
- the defined pivot axis is at a distance from the area of the initially arranged fixed axis of rotation of the core and the adjustable deflection roller can be pivoted over part of the circumference of the wadding roll so that when it is transferred to the ejection position and the tensioning of the belt, a rolling surface that preferably descends from the horizontal downward is generated for the wadding roll to be ejected and the adjustable Deflection roller at the end of the pivoting movement in a region near another, horizontally outer stationary deflection roller comes to rest on its inner side facing the wadding to be ejected.
- the adjustable deflection roller which can be adjusted with it, therefore, no more space is required than is already provided for the further deflection rollers.
- At least one of the outer rollers can be designed to be correspondingly displaceable and / or pivotable, as a result of which the additional effort for the compensation element or elements is reduced to a minimum.
- the tensioning of the belt during the winding process, the belt drive, the adjustment of the deflection roller in question between the working position and the ejection position, optionally the loading of the compensating element and / or the removal of the wadding roll to a transport device or the like is at least partially automated and controlled by a control device.
- a further deflection roller is rotatably mounted on a passive swivel arm, via which it during the transfer of the adjustable deflection roller from the working to the eject position due to its own weight and the weight of the passive Swivel arm can be pivoted downwards in order to maintain the required belt tension or, as a compensating element, at least a part of the adjustable deflection roller during the transfer from the working position to the ejection position Compensate for belt length changes occurring in sections.
- a passive deflection roller rotatable about a fixed axis is provided, with which the belt comes into contact only in the course of the downward swiveling movement of the passive swivel arm.
- the deflection roller mounted on the passive swivel arm, forming a compensating element also compensates for at least the majority of the belt length changes that occur in sections during the return of the adjustable deflection roller into the working position and / or during the new formation of the loop, which preferably occurs when a new core is inserted.
- the passive swivel arm can be rotatably mounted at one end, for example around the fixed axis of a further deflection roller, and can carry the deflection roller forming a compensating element at the free end.
- the deflection roller which is adjustable between a working and an ejection position, can preferably be swiveled about a defined axis by means of a swivel lever with an associated drive.
- the drive can comprise, for example, a piston / cylinder unit.
- the cotton wool can be fed, for example, over several calender rolls, preferably at least one calender roll being adjustable from its working position, in particular being pivotable.
- the belt can be provided with openings and / or openings through which air which passes between the wadding roll and the belt can escape to the outside.
- the winding process is thus easier to control overall.
- a chain or the like can in principle also be provided.
- the winding device can be used in particular in the combing mill, where it receives, for example, a fleece that runs out of a drafting system and is fed in via sweeping plates, calender rollers and / or the like. The finished winding is then fed to a combing machine.

- FIGS 1 to 3 show a purely schematic representation of a winding device 10 for producing a wadding roll 12.
- a winding device 10 can be used to roll up a nonwoven, a pile or wadding of fiber material into a roll before the fiber material is subjected to a further treatment .
- the winding device can serve, for example, in a combing mill to receive a fleece that runs out of a drafting system and is fed in via sweeping plates, calender rollers 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 a cotton wool feed 16, which in the present case is formed by a sheet metal bent at the outlet end.
- the cotton wool 14 is wound on a core H serving as a core, which is rotatably mounted about a fixed axis A in the illustrated embodiment.
- This sleeve H is driven by an encircling, endless belt 18, by means of which a loop 20 is formed between two deflection rollers R1 and R2, in which the sleeve H is received during the winding process.
- the sleeve H or the cotton wadding 12 that is formed is passed through the belt 18 driven counterclockwise, as indicated by the arrow F.
- the loop 20 of the belt 18 which surrounds the sleeve H and thus the cotton wadding 12 which is formed becomes larger with increasing cotton wadding 12, the belt 18 being tensioned by a tensioning device 22 during the entire winding process.
- This tensioning device 22 comprises a tensioning roller R4 with an associated linear guide 24.
- the belt 18 is guided over further deflection rollers R3, R5 and R6 and the tensioning roller R4 adjustable along the linear guide 24 so that it is tensioned over the tensioning roller R4 in a plane perpendicular to the plane containing the axes of the two deflection rollers R1 and R2 is.
- another belt guide is also possible, in which the belt is tensioned via the tensioning roller R4, for example in a plane that is parallel to the plane containing the axes of the two deflection rollers RI and R2.
- the right deflection roller R1 can be adjusted between a working position intended to form the loop 20 (see FIG. 1) and an ejection position (see FIGS. 2 and 3) into which this deflection roller R1 can be transferred in order to eject the wadding roll 12 by tightening the belt 18 while lifting the loop 20.
- this deflection roller R1 which is adjustable between a working position and an ejection position, can be pivoted about a defined or fixed axis B via a pivoting lever 26.
- the further deflection roller R6 can also be pivoted, which is also arranged on the pivot lever 26 at a fixed distance from the deflection roller R1.
- This pivot lever 26 comprises a first lever part 28, which is pivotally mounted at one end about the axis B, the other end of which is connected to a further lever part 30 perpendicular to the lever part 28, at the two ends of which the deflection rollers R1 and R6 are arranged.
- the lever part 28 is in one place with the lever part 30 connected, which is offset towards the middle of the guide roller R6.
- the defined pivot axis B is provided directly below the sleeve H arranged in the loop 20 or close to and below the region of the axis of rotation A of the sleeve H which is fixed during the winding process.
- the loop 20 produced for the formation of a winding between the deflection rollers R1, R2 extends downwards in the vertical direction.
- the subsequent ejection of the wadding roll 12 takes place at least essentially horizontally (see FIGS. 1 and 2).
- the two deflecting rollers R1, R6 arranged at a fixed distance from one another can be pivoted such that with the transfer of the adjustable deflecting roller R1 into the eject position (see FIGS. 2 and 3) and the tightening of the belt 18, a rolling surface that slopes slightly downward from the horizontal is generated for the wadding roll 12 to be ejected and the further deflection roller R6 is released from the belt 18 in the course of the pivoting movement.
- At least one compensating element Ri for example formed by at least one of the deflecting rollers R2 to R5, is provided, by means of which at least the majority of during the transfer of the adjustable deflecting roller R1 from the working position into the ejecting position and under suspension the tightening of the belt 18, which occurs in sections 20, is compensated for belt length displacements occurring in sections, while during the winding process, due to the loop 20 increasing in length with the wadding roll 12 becoming larger, sections of belt length displacements occurring at least predominantly are compensated for by the tensioning device 22.
- the further deflection roller R6 arranged on the pivot lever 26 forms such a compensating element.
- at least one of the Deflection rollers R2, R3, R5, R6 can be designed to be correspondingly displaceable and / or pivotable in order to form at least one such compensation element.
- the respective compensating element preferably also compensates for at least the largest part of belt length displacements occurring in sections during the return of the adjustable deflection roller R1 into the working position.
- such a compensating element can preferably also be used to compensate for the belt length shift, as occurs during the new formation of the loop 20, for example, when a new sleeve H is inserted.
- the respective compensating element can be acted upon independently of the tensioning device 22.
- the deflection roller R1 which is adjustable between a working position and an ejection position, is adjustable independently of this tensioning device 22, for which purpose a separate drive can be provided in particular.
- the pivot lever 26 carrying the two deflecting rollers R1 and R6 is pivoted downwards to eject the wadding roll 12.
- This pivoting into the ejection position shown in FIGS. 2 and 3 is thus supported, inter alia, by the weight of the pivot lever arrangement carrying the deflection rollers R1, R6.
- the deflection roller R1 is returned to the working position shown in FIG. 1 by pivoting the pivot lever 26 back.
- a drive associated with this pivoting lever arrangement and independent of the tensioning device 22 can therefore, as a rule, as well as the means for acting on the compensating element, be dimensioned smaller than the tensioning device 22, by means of which, as a rule, significantly greater forces are to be applied during the winding process, which in the case of a during this winding process, a sleeve H rotatable about a fixed axis A can in particular also be larger than the weight of the wadding roll 12.
- the deflection rollers R1, R2, R3, R5 and R6 and the tensioning roller R4 have essentially the same diameter as the respective sleeve H.
- the axes of the rollers and the sleeve H inserted into the loop 20 are parallel to one another.
- the belt 18 is driven by the deflection roller R5, which is arranged in the same vertical plane as the tensioning device 22 and below it.
- the tensioning roller R4 assumes its upper end position, from which it is transferred to the lower end position shown in FIG. 2 during the winding process.
- the further deflection roller R3 which is offset slightly downward relative to the tensioning roller R4 and is located between it and the deflection roller R2, is arranged in such a way that the belt 18 always surrounds the tensioning roller R4 regardless of its position with a wrap angle of 180 °.
- the tensioning device 22 comprises a cylinder / piston unit acting on the tensioning roller R4, by means of which the tensioning roller R4 can be adjusted in the vertical direction and by means of which the tensioning forces desired in each case during the winding process can be generated.
- the wadding 14 is fed to the wadding feed 16, formed in the present case by a sheet metal bent on the outlet side, via calender rollers 34, the axes of which lie in a curved plane.
- a gripping arm 36 is around the deflection roller R2 an axis D is pivotally mounted, through which a new sleeve H is removed from an upper sleeve magazine 38 in the manner shown in FIGS. 1 to 3 and brought into the position provided for the winding process.
- the sleeve H forming the core is then rotated about a fixed axis A as a result of the drive by the belt 18, the desired belt tension being at least essentially predetermined by the tensioning device 22 during this winding process.
- the cotton is separated. This ensures, in particular, that the winding does not wind up again before the rolling out process.
- a possible variant of a separation is that when a predetermined wound length of cotton is reached, the cotton feed is interrupted by the calender rollers while the belt is still in motion for a certain time. This causes a break in the cotton wool in the area of the front calender roll.
- the tearing end can be positioned at a defined position on the wadding roll by a predetermined time in which the finished wound wadding roll is still rotated by the belt when the calender rolls are at a standstill.
- the lever arrangement comprising the pivoting lever 28 and the deflection rollers R1 and R6 attached to it is pivoted downward in the manner shown in FIG. 2, whereupon the wadding roll 12 is ejected at least substantially horizontally to the right and transferred to the transport device 40.
- a new sleeve H is then introduced in the manner shown in FIG.
- the deflection roller R1 again assumes the upper working position shown in FIG. 1.
- the tensioning roller R4 must also assume its upper end position shown in FIG. 1.
- the tensioning device 24 is at least essentially provided only for the compensation of belt length displacements occur in sections during the winding process and which can be attributed to the loop 20 which becomes larger as the wadding roll 12 increases.
- This tensioning device 22 can thus be dimensioned correspondingly large.
- the generally smaller belt length displacements are compensated for during the pivoting of the deflection roller R1 and the tensioning of the belt 18 to be carried out for ejecting the wadding roll 12 by means of the at least one compensating element Ri provided in addition to the tensioning device 22. This therefore ensures, in particular, faster compensation when dispensing the reel and / or when inserting a new sleeve H.
- the deflection roller R1 which is adjustable between a working and an ejection position, can be pivoted about a defined axis C via a pivot lever 32.
- the defined pivot axis C is arranged at a clear distance from the region of the initially fixed axis of rotation A of the sleeve H.
- this pivot lever 32 carries only the deflection roller R1, which is arranged at the free end of this pivot lever 32, which at the other end by the defined, i.e. fixed axis C is pivotally mounted.
- this defined pivot axis C is arranged in the region of the circumference of the deflection roller R3 in the illustrated roller arrangement.
- the adjustable deflection roller R1 can be pivoted over part of the circumference of the wadding roll 12 in such a way that when it is transferred to the ejection position and the tensioning of the belt 18, a rolling surface for the wadding roll 12 to be ejected, preferably falling slightly downward from the horizontal, is produced and the adjustable one Deflection roller R1 at the end of the pivoting movement in a region near another, horizontally outer deflection roller R6 'comes to rest on the inner side thereof facing the wadding roll 12 to be ejected.
- the deflection roller R6 ' which can be pivoted together with the deflection roller R1 together with the deflection roller R1 is thus provided in the present case, which can also be stationary, for example.
- this deflection roller R6 'no longer has to be pivoted accordingly together with the deflection roller R1 to open the loop 20.
- At least one of the deflecting rollers R2, R3, R5, R6 and R6 'and / or at least one further deflecting roller or the like can again serve as a compensating element and can accordingly be displaced and / or pivoted accordingly.
- at least one further deflection roller can also form such a compensation element Ri.
- the deflection roller R1 After pivoting the pivot lever 32 downward, the deflection roller R1 is arranged to the left of the deflection roller R6 'and somewhat above it (see FIGS. 5 and 6). An extremely compact arrangement is thus achieved in spite of the pivotable design of the deflection roller R1.
- the calender rolls 34 via which the cotton 14 is fed to the cotton feed 16 formed by a bent sheet metal, are in this case in a common plane.
- FIGS. 4 to 6 has at least essentially the same structure as the winding device described above with reference to FIGS. 1 to 3, the same parts being assigned the same reference numerals.
- FIG. 4 shows the winding device 10 again in the phase at the beginning of the winding process with the loop 20 formed and the deflection roller R1 pivoted upwards accordingly.
- FIG. 5 shows the winding device 10 in one phase at the end of the winding process.
- the wadding roll 12 is again ejected essentially horizontally to the right.
- FIG. 6 shows the phase of inserting a new sleeve H by means of the correspondingly pivotable gripping arm 36. This insertion takes place with the formation of the new loop 20 (see FIG. 4) against the forces applied by the respective compensating element or the respective compensating elements Ri.
- the new sleeves H are again taken from an upper sleeve magazine 38.
