Abstract

This invention concerns a winding device (10) for producing a roll of batting (12). For this purpose, the batting (14) is wound on a rotating core (H) driven by an endless belt (18). The core can be positioned in a loop (20) of the belt (18) formed between two pulleys (R1, R2) which can be stretched by means of a tension-setting device (22). As the size of the roll (12) increases, the size of the loop increases. At least one (R1) of the deviation pulleys (R1, R2) can be placed between a working position designed to form the loop (20) and an ejection position, into which the pulley can be positioned to eject the roll of batting (12), the belt (18) being stretched when the loop (20) is removed. In addition to the tension-setting device (22), at least one compensating element (R6, R6'', R2, R3, R5, R6') is provided to compensate for at least the greater part of the changes on belt length which arise in certain zones when the adjustable pulley (R1) is moved from a working position to an ejecting position and the belt (18) tightens during removal of the loop (20). On the other hand, the changes in belt length which arise during winding in certain zones as the loop (20) grows larger with increasing size if the batting roll (12) are compensated for the most part by the tension-setting device (22).

Description

Produce the coiler device of lap

The present invention relates to one in order to produce the coiler device of a lap, wherein lap is wound onto on the core pipe that endless strap drove by a circulation, it can be placed between two guide rollers formed belt and hang down in the ring, the ring that hangs down increases along with lap and becomes big, belt comes tensioning by a tensioning apparatus, here at least one guide roller can and be dished out and move between the position in the operating position that forms the ring that hangs down, and makes belt tighten lap is dished out by the ring that hangs down being separated scatter when guide roller is transferred on the position of dishing out.

From German patent DE-PS 910 754 is known above-described coiler device arranged, the core pipe that wherein is used for constituting lap is loosely to be placed in belt to hang down in the ring, therefore transfers to from the operating position when dishing out the position and encircles by dismissing to hang down that the variation in the strap length that some line segment occurred must be compensated by tensioning apparatus when belt is tightened when the removable guide roller.Tensioning apparatus mainly is to be designed to be used for compensating in winding process the variation that increases the strap length that occurs at some line segment when making the ring that hangs down become big owing to lap.Therefore this coiler device has a shortcoming, and promptly lap speed of dishing out and the speed that more renews the core pipe are subjected to the restriction of the speed that tensioning apparatus can follow the variation of strap length.

The objective of the invention is to propose a kind of than the above-mentioned coiler device that improves to some extent, it can reliably and promptly realize dishing out of lap with simple and compact structure as far as possible, thus also special as far as possible promptly the lap of finishing and newly the core pipe exchange.

According to the present invention, this task solves like this, promptly except tensioning apparatus, also be provided with a compensating element, at least, by its effect, at least the major part that changes in the strap length that the removable guide roller is transferred to when dishing out the position from the operating position and the belt that forms when the ring that hangs down is dismissed occurs at some line segment when tightening can obtain compensation, in winding process because lap increases the strap length variation of some line segment that vertical ring occurred that becomes big is then at least mainly compensated by tensioning apparatus.

Because tensioning apparatus only mainly changes owing to lap increases the strap length that vertical ring occurred that becomes big in winding process in order to compensation, so its size can design like this, promptly need not owing to considering that the lap of as far as possible promptly dishing out is subjected to any restriction, suitable design that on the contrary can be by the additional compensating element, that is provided with is irrespectively improved the speed of dishing out without a doubt and with the size of tensioning apparatus by needed mode, particularly can also be apace lap of finishing and the new core pipe by bobbin or analog constituted be changed.Therefore additional compensating element, can come particular design like this, it can be changed in general very little strap length compensate rapidly, and tensioning apparatus then is to be used for coming bigger strap length variation is compensated lentamente with bigger power.Therefore can not only realize the quickish belt unlatching of ring of hanging down according to the present invention, and can also realize the lap that quickens to dish out and irrelevant with tensioning apparatus.

Adopt in the embodiment of this advantage of the compensation preferential recommendation in practice that in the belt process of hanging down that ring is opened and lap is dished out, has nothing to do basically with tensioning apparatus.Its core pipe can rotate round a fixed axis in winding process, and belt tension can be set by tensioning apparatus in winding process at least basically.In the case, the power that is produced in winding process also may be greater than the weight of lap.Because the design of additional compensating element, is irrelevant with the sizable tensioning apparatus of size, therefore still can carry out belt fast hang down the unlatching that encircles and fast lap dish out.

The effect that compensating element, can give special loading or only bear gravity.Under first kind of situation, compensating element, preferably and tensioning apparatus irrespectively loaded the corresponding compensation power that produces.

Corresponding therewith, according to a preferential embodiment, can irrespectively regulate with tensioning apparatus in the operating position and the removable guide roller of dishing out between the position, this can realize by an independent drive unit.

Preferably also at least can be in turning back to the process of operating position and/or form again when introducing a new core pipe that the major part in the strap length variation that some line segment occurred is compensated in the process of the ring that hangs down by compensating element, to the removable guide roller.Thereby can make lap irrelevant with the corresponding size of tensioning apparatus with the whole exchange process acceleration of new core pipe.

The vertical ring of belt for example can extend downwards with vertical direction, thereby can make lap at least to become flatly to dish out basically.But the ring that hangs down also can extend with horizontal direction, or becomes with vertical direction.

If can be in the operating position and the guide roller that moves of dishing out between the position be arranged on the swing arm and rotate round a fixed axis, then can obtain a simple and solid especially structure.

A device compact especially, that also only account for minimum position when especially even swing arm is outwards shown if desired, then can realize like this, promptly the removable guide roller rotates with another guide roller between the position with dishing out in the operating position, and these two guide rollers are arranged on the swing arm with a fixed range mutually.Compensating element, just can constitute by another guide roller on the swing arm like this.Here two guide rollers preferably rotate like this, promptly transfer to and be preferably formed as one from the downward-sloping doff plane of horizontal direction when dish out position and belt are tauted at the removable guide roller, so that dish out at lap, and another guide roller is preferably thrown off from belt in rotation process.

Fixing swinging axle for example can be arranged on the core pipe initial fixation rotating shaft scope near, preferably below it.But it also can be arranged on the regional interior or consistent with it of core pipe initial fixation rotating shaft in principle.

In another advantageous embodiment according to coiler device of the present invention, fixing swinging axle is provided in a side of from the initial fixation rotating shaft zone of core pipe a segment distance part, and the removable guide roller is to move like this on a part of periphery of lap, make it be preferably formed as one when dish out position and belt are tightened and be used for the lap of dishing out from the downward-sloping doff plane of horizontal direction transferring to, and the removable guide roller is in the inboard of facing the lap of waiting to dish out near another in the horizontal direction in the zone of the static guide roller in the outside at it in the terminal of swing.Like this, swing arm and just do not need to account for more position than the other guide roller that has been provided with guide roller that its moves together.

Can utilize the suitably mobile and/or swing of at least one guide roller to constitute a corresponding compensation element in principle, the surcharge of required compensating element, is minimized.

According to an embodiment of recommending in the practice, the driving of the tensioning of belt, belt and related guide roller are the operating position and the moving between the position of dishing out in winding process, and be transported on a conveying arrangement or the similar device to the loading of compensating element, and/or lap in case of necessity, at least realize the automation of part, and control by control device.

According to the present invention, task noted earlier also can further solve like this, be that another guide roller is to be installed in rotation in the passive swing arm, by it act on that the removable guide roller is transferred to from the operating position the process of the position of dishing out since the weight of weight of itself and passive swing arm and to lower swing to keep required belt tension, perhaps at least the removable guide roller is transferred to the part that the strap length that occurs at some line segment the process of the position of dishing out changes from the operating position and is compensated as a compensating element.

Be preferably between guide roller that is installed in the passive swing arm and another guide roller that rotates round a fixed axis the passive guide roller that an energy rotates round fixed axis is set, it only rotates in the process in passive swing arm and just contacts with belt.

Comparatively suitable is, also at least the removable guide roller is compensated in the major part that the strap length that some line segment occurred changes turning back to during the operating position and/or form the ring process of hanging down again when putting into new core pipe by a guide roller that constitutes a compensating element, that is contained in the passive swing arm.

Passive swing arm can be at one end for example rotated round the fixed axis of another guide roller, and a guide roller that constitutes compensating element, is housed on its free end.

Passive swing arm does not have transmission device, and preferably has the swing arm of transmission device by one and swing round a fixed axis at operating position and the removable guide roller of dishing out between the position.This transmission device for example can comprise a piston/cylinder unit.

The supply of cotton-wool for example can realize that wherein preferably at least one roll can outwards move from its operating position, particularly outwards swing by many rolls.

The basic structure of another embodiment of Fig. 7 coiler device is at the schematic diagram of winding process incipient stage.

Fig. 1-3 only schematically illustrates one in order to producing the coiler device 10 of lap 12, and so in principle coiler device 10 is in order to the net of fibrous material or flocculus are rolled into a fiber roll, and then fibrous material is further processed.Therefore coiler device for example can be used for the combing workshop receive from drawing frame output, and the web supplied with through reversing plate, roll and/or like, and the lap that is produced then is supplied to combing machine.For simplicity, the fibrous material of being supplied with that relates to below only is meant cotton-wool, but this can not be interpreted as the meaning with restriction.

Cotton-wool 14 is on a bobbin H as the core pipe, it can be provided with rotationally round a fixed axis in an illustrated embodiment, this bobbin H is driven by the endless strap 18 of a circulation, belt forms a vertical ring 20 between two guide roller R1 and R2, the bobbin H in winding process just is received within this ring that hangs down.

In the case, the lap 12 of bobbin H or institute's coiled is by belt 18 and counterclockwise to drive, as shown by arrow F.Round bobbin H, thereby the vertical ring 20 that is holding around the belt 18 of formed lap 12 will change along with the increase of lap, and wherein belt 18 comes tensioning by a tensioning apparatus 22 in whole winding process.This tensioning apparatus 22 comprises an idler roller R4 and the straight line navigation device 24 that links to each other with it.

Belt 18 is also by other guide rollers R3, R5, R6 with can guide like this along the idler roller R4 that straight line navigation device 24 moves, and makes belt 18 give tensioning by idler roller R4 in a plane with the axis that contains two guide roller R1 and R2 becomes vertical plane.But also can adopt the belt guide of other modes in principle, wherein belt by idler roller R4 for example can one with the plane of plane parallel of the axis that contains two guide roller R1 and R2 in give tensioning.

At two guide roller R1 that constitute the ring 20 that hangs down, among the R2, the guide roller R1 in right side can dish out the position (referring to Fig. 2 in an operating position (referring to Fig. 1) and that forms the ring 20 that hangs down, 3) move between, the dismission by the ring that hangs down when guide roller R1 transfers to this and dishes out the position makes belt 18 tensionings and lap 12 is dished out.

As from Fig. 1-3 as can be known, this can rotate round a fixed axis B by swing arm 26 in the operating position and the guide roller R1 that moves between the position that dishes out.Also have another guide roller R6 to swing together with guide roller R1.It is arranged on equally on the swing arm 26 and with guide roller R1 and maintains a certain distance.Swing arm 26 comprises one first lever 28, and its end can rotate round axle B, and the other end is same to be connected with perpendicular another lever 30 of lever 28, at the two ends of lever 30 guide roller R1 and R6 is housed.Here the position that is connected with lever 30 of lever 28 is the side of deflection guide roller R6 for its mid point.

Fixed rotating shaft B is located immediately at the below that being arranged on the bobbin H in the ring 20 that hangs down, or the zone of the fixed rotating shaft A that is close at winding process middle bobbin H below.

According to Fig. 1, at guide roller R1, vertical ring 20 extensions downwards that form in order to the coiling lap between the R2 with vertical direction.Dishing out of back to back lap 12 is into (referring to Fig. 1 and 2) of horizontal direction at least basically.

Two guide roller R1 that keep certain distances mutually that in aforesaid way, are equipped with on the set swing arm 26, R6 is swing like this, promptly along with removable guide roller R1 transfers to tightening of position of dishing out (referring to Fig. 2 and 3) and belt 18, can form one for the downward-sloping slightly doff plane of horizontal direction so that dish out lap 12, and another guide roller R6 breaks away from from belt 18 in swing process.

Importantly: except tensioning apparatus 22, also be provided with one at least and constitute a compensating element, Ri by one among the guide roller R2-R5, effect by it can be compensated the major part that removable guide roller R1 transfers to the process of the position of dishing out from the operating position and the strap length that occurs in dismissing some line segment of tightening in the process to be occurred of belt 18 that the ring that hangs down took place at 20 o'clock changes at least, in winding process because the increase of lap 12 becomes the strap length variation that occurs in the section of big vertical ring 20 then compensates substantially by tensioning apparatus 22 at least.

In the case, another guide roller R6 that is arranged on the swing arm 26 has constituted such compensating element.At least guide roller R2 in principle, R3, R5 all can be designed to movably one of among the R6 and/or can swing, so that constitute such compensating element.By the suitable compensation element, preferably the major part that changes of the strap length that also at least removable guide roller R1 is occurred at some line segments in turning back to the process of operating position is compensated.The process that preferably also can form the ring 20 that hangs down again by this compensating element, when for example putting into new core pipe plays compensating action to the variation of strap length in addition.

In order to produce corresponding compensation power, compensating element, can irrespectively be loaded with tensioning apparatus 22.In the operating position and dish out that removable guide roller R1 can irrespectively regulate with tensioning apparatus 22 between the position, an independent drive unit can be set especially in addition to this.

As from Fig. 1-3 as can be known, the swing arm 26 that two guide roller R1 and R6 are housed rotates in order to dish out lap 12.The position of dishing out shown in this Fig. 2 of turning to and 3 is to support by the weight of the swing arm device that is loaded with guide roller R1, R6.After lap 12 for example was transported to a conveying arrangement 40 (referring to Fig. 2), guide roller R1 just turned back to operating position shown in Figure 1 by the past back rotation of swing arm 26.To this swing arm device set, generally can be with the irrelevant drive unit of tensioning apparatus 22 as the loading measure of compensating element,, that designs than tensioning apparatus 22 is littler.In winding process, generally need obviously bigger active force, may be under the situation of the bobbin H that it rotates round a fixed axis A in winding process greater than the weight of lap 12.In addition, general also big strap length the variation compensated by tensioning apparatus 22 in winding process, as situation by at least one additional compensating element,, this compensating element, removable guide roller R1 transfer to from the operating position the process of the position of dishing out and dismiss belt 18 that the ring that hangs down took place in 20 o'clock tighten and effective especially when guide roller R1 turns back to the operating position.The compensating action that at least one related ancillary relief element is produced can be than faster with the effect of larger-size compensation arrangement 22.

Guide roller R1, R2, R3, R5 has the diameter identical with bobbin H basically with R6 and idler roller R4.Each deflector roll and the axle that is placed on the bobbin H in the ring 20 that hangs down are parallel to each other.Belt 18 drives by guide roller R5, and it is arranged in the same vertical plane with tensioning apparatus 22, and is positioned at its below.

In Fig. 1, idler roller R4 is in the upper terminal position, from it transfers to lower terminal end position shown in Figure 2 winding process here.Also be provided with one here like this for downward bias and between idler roller R4 and guide roller R2 slightly another guide roller R3 of idler roller R4, make the cornerite of belt 18 on idler roller R4 remain 180 ° and with its location independent.

In the case, tensioning apparatus 22 comprises that one is carried in the cylinder/piston unit on the idler roller R4, by it idler roller R4 is moved in vertical direction, and provide required tension force all the time in winding process.

Cotton-wool 14 is to supply by a cotton-wool transport 16 that is constituted at the sweeping plate of outlet side with through roll 34 in the case.The axle of these rolls is positioned on the plane of a bending.Above guide roller R2, be provided with a gripping arm 36, can rotate, can from top bobbin storehouse 38, take a new bobbin N away in the mode shown in Fig. 1-3 by it, and drop it off the position of winding process defined round axle D.

In winding process (Fig. 1) as the bobbin H of core pipe owing to rotate round a fixed axis A by the driving of belt 18.Here required belt tension is set substantially by tensioning apparatus 22 at least in winding process.

After winding process finishes and before the process of dishing out, separate cotton-wool.Must guarantee especially that for this reason lap no longer reeled before the process of dishing out.A kind of possible separation method is: when reaching predetermined cotton-wool coiling length, be interrupted through the cotton-wool input of roll, and belt still keeps the operation of certain hour.So cotton-wool broken end takes place in the roll zones forwardly.Through a preset time wherein under the static situation of roll belt still move and make lap to reel to finish, the cotton-wool termination is positioned on the fixed position of lap.

Then, swing arm 28 and the leverage that comprises guide roller R1 and R6 adorned thereon rotate in mode shown in Figure 2; Lap 12 is dished out to the right with substantially horizontal direction at least thus, and transfers on the conveying arrangement 40.Then put into a new bobbin H in mode shown in Figure 3.In order to restart winding process, guide roller R1 occupies operating position, top shown in Figure 1 again.In order to begin winding process, idler roller R4 also must be in upper terminal position shown in Figure 1 again in addition.Therefore tensioning apparatus 22 mainly only changes owing to lap 12 increases the strap length that ring 20 changes of hanging down are occurred greatly on some line segment in order to compensate in winding process.This tensioning apparatus 22 can be designed to bigger size.Less strap length variation when on the contrary, generally when guide roller R1 rotates and when dishing out lap 12 belt 18 being tightened then is additional to tensioning apparatus 22 set compensating element, Ri by one at least and is compensated.This particularly considers in lap output and/or the quick compensation when inserting new bobbin H.
