Flyer spindle machine flier

Technical field

The utility model relates to a kind of flyer spindle machine flier that is used for Speed frames, its have on the flier arm rotatable that be provided with, by the end finger bar with have the end finger that the end finger arm of end finger plate constitutes, the turning cylinder of this end finger is positioned at the center of the connecting portion of end finger and flier arm, and rotate with default radius (R) round the bobbin center, wherein, the end finger bar is positioned at outside the radius (R), the end finger arm is arranged on this end finger bar, and the end finger bar can be loaded by the functional unit that works on this end finger bar transverse to turning cylinder, and end finger can rotate in the position that breaks away from.

Background technology

In the automation of the continuous development in rove field the automatic replacement that the design of flyer spindle machine flier and end finger proposes more and more newer requirement, particularly bobbin is constantly developed into various forms.Bobbin is replaced and can be realized, for example, by having the decline that is erected at the bobbin rail that twines full bobbin on the bobbin support, and roll away from by the flier zone thus, so that this twines full bobbin next by with the bobbin receiving system in bobbin rail height, the Speed frames of packing into, this twines full bobbin and utilizes it to take out from Speed frames yarn tube end freely.

In order to ensure after the sky yarn tube of packing into, end finger abuts on the yarn tube surface effectively by its end finger plate, for example open by DE 3004165 C2, promptly have cylindrical space in the inside of flier arm of supporting end finger, be provided with in this cylindrical space that an end is connected with the flier arm and other end is connected with the rove tube and around the columniform torsionspring of rove tube.This spring plays end finger is pressed to effect on the coil yarn tube.The shortcoming of this solution is, be wound with on the yarn tube of rove, on the yarn tube or the continuous thrust that exists on the rove that twines, this thrust can affact on the material that is wound and forms bobbin negatively by the diameter that bobbin increases by spring.In addition, special requirement is proposed in the design of end finger and end finger plate.This must design special guide cylinder and baffle plate, replaces so that can fully realize automatic bobbin.

Disclose the flyer spindle machine flier that is used for Speed frames by DE 195 43 716 A1, it has the end finger that is made of end finger bar and the end finger arm that has the end finger plate.The end finger bar that is positioned at outside the turning cylinder can rotate by the functional unit that works on the end finger bar transverse to turning cylinder, thereby end finger can be a rotated position, and can remain in this position.Therefore end finger so rotates, and promptly twining full bobbin can be taken out by the pivot region of flier.Automatically begin spinning in order to realize the revolution of end finger the time, must so design baffle plate on the flier arm, i.e. setting abuts to the center of gravity of the end finger on each baffle plate, to guarantee that end finger rotates when beginning to spin on bobbin.

In disclosed device, the opening on a large scale of this matching requirements end finger, this has produced difficulty, and promptly in the beginning spinning process, end finger remains in the position of its rotation.For this reason, primary reason is that the baffle design on the flier arm is the baffle plate of rigidity.By the rigid location of end finger, the loss of special contact component takes place in this position, and thus in the Speed frames position that has changed the end finger rotation in service.As time goes on, the result of this loss causes the uncertain of end finger center of gravity, and promptly in the beginning spinning process, end finger can not realize turning to the beginning yarning position immediately.This causes inevitably, promptly because little flier spacing (diagonal pitches of parts) is particularly in bigger bobbin specification, destroyed thereby end finger is in contact with one another.

The utility model content

The purpose of this utility model is, further design the flyer spindle machine flier of the described type of beginning in this wise, promptly can realize being used for opening on a large scale of bobbin replacement, and in order to begin spinning process automatically, the end finger empty yarn tube that automatically leads, end finger can not load on yarn tube or the bobbin by thrust.

This purpose solves thus according to the utility model, and at least one spring part promptly is set on the flier arm, and its spring force only as one man affacts on the end finger in pivot region, and in this pivot region, the center of gravity of end finger is positioned within the radius (R).Turning cylinder is positioned at the center of the connecting portion of flier arm and end finger, and this turning cylinder rotates with radius (R) round the bobbin center.When beginning to spin, flier is mobile to rotatablely move together with turning cylinder, and the center of gravity of end finger must be positioned at outside the radius (R), realizes the rotation of end finger plate on bobbin yarn tube thus.In addition, the center of gravity of end finger is arranged in the end finger bar, and the weight of end finger bar is greater than the weight of end finger arm.In the rotatablely moving of flier, the end finger bar with center of gravity, and is resisted against on the bobbin yarn tube by the end finger arm to external compression thus based on centrifugal force.When being positioned within turning cylinder-bobbin center-radius when the center of gravity of end finger is beginning to spin, the end finger arm is not turned on the bobbin yarn tube, but upset outwardly.Until the center of gravity that the arrives end finger position outside radius (R) still just in time, because its center of gravity rotatablely moves when carrying out at end finger, automatically in the beginning yarning position, end finger does not have spring-load and rotates and upset round its turning cylinder.Yet in order to allow end finger open or to rotate so on a large scale, the center of gravity that is end finger is positioned within the radius (R), and when bobbin is replaced, can realize not having difficulty ground and be shifted out around full bobbin by flier, end finger must resist the elastic force that is arranged on the spring part on the flyer spindle machine flier and move.After the functional unit that works on the end finger bar being used to open unclamped end finger, next spring part worked, and promptly end finger at this time goes back to or put go back to its position, and promptly the center of gravity of end finger is again outside radius (R).

In addition, particularly advantageously be, utilize that spinning process is not subjected to the end finger pressure influence that improves constantly on bobbin according to flyer spindle machine flier of the present utility model.Therefore further advantageously, stop the motion of end finger with respect to spring part by spring part, promptly spring part collides the hard baffle plate on the flier arm, and flier arm and/or end finger are impaired.Thus by according to flyer spindle machine flier of the present utility model, guaranteed to be used for to begin automatically the desired position of the end finger that spins, and guaranteed that end finger is used to pipette the necessary position that twines full bobbin.

Spring part is the member of fixture preferably, and this fixture is arranged between end finger and the flier arm, and it is used for end finger fixing on the flier arm.Therefore, when spring part damages, can change these damage parts simply.Yet spring part also can be directly installed on the flier arm.

According to another design of the present utility model, spring part is a support rod, and its fixedly eyelet by flier arm and end finger guides jointly.In addition, this support rod non-rotatably is fixed on the flier arm by the end of its below, and extend in the folder by the end of its top, and this folder is positioned on the fixedly eyelet of top of flier arm, and folder clamps in this flier arm.In this embodiment, as being used for the baffle plate of end finger bar in the position of rotating, wherein, the center of gravity of end finger still is positioned at outside the radius (R) folder simultaneously.By the layout of folder, the contact between end finger bar and the flier arm then can not take place.For wider the opening of end finger, and for the center of gravity of end finger changes the position within radius (R), to the secondary action again of end finger with thus by the extruding of end finger bar on the folder, folder rotates with reversing of support rod by functional unit.In case the end finger bar is discharged by functional unit, support rod tightens, and folder rotates at its each initial position thus.

According to favourable improvement project of the present utility model, can be by being positioned at the folder on the fixing eyelet and the spacing of the baffle plate on the flier arm, regulate the rotate path of folder and the spring of support rod thus, thus, the rotation path of end finger can be by the position influence of its outermost position of opening to no spring-load.In order to realize the spring of support rod, another possibility is, promptly folder on the one hand with the flier arm on baffle plate do not have spacing, and thus antitorque fixing, support rod is rotatably fixing on the fixedly eyelet below the flier arm on the other hand.In this embodiment, support rod end thereunder has fixedly fish platee, this fixedly fish platee in this position simultaneously as the baffle plate that is used for end finger, in this position, the center of gravity of end finger is still outside radius (R).If end finger is further opened by this position, the end finger arm compresses fixedly fish platee so, and rotates with reversing of support rod.In the setting and the position of resting position, the rotation path of the spring-load of end finger can be affected according to the fixedly fish platee of support rod.

Another favourable design of the utility model is, is provided with the baffle component on the fixedly eyelet of the top that is positioned at the flier arm.It is designed for the accommodation section by the fixture of the common guiding of fixedly eyelet of the top of flier arm and end finger on the one hand, and has spring part on the other hand, when end finger when the zone is turned round, in this zone, the center of gravity of end finger is positioned at outside the radius (R), wherein, spring part is controlled by its spring force of resisting the end finger bar.If end finger is discharged by the functional unit that affacts on it, the spring force of spring part produces gyroscopic action in the zone that the center of gravity of end finger is positioned at outside the radius (R) so, so that end finger reaches the beginning yarning position in order to begin to spin.This baffle component can be the folder of similarly having described, and it clamps support rod on the one hand, and additionally has spring part.In this situation, folder continuously apart from abut on the baffle plate of flier arm, and the part of the below of support rod can be fixed on the fixedly eyelet of below of flier arm equally antitorquely.As selecting, be fixed on the flier arm in addition, can on the fixedly eyelet of each above and below, use the fixture of separating, be independent of each other connection in order to make end finger.The baffle component that is positioned on the fixedly eyelet of top of flier arm might for example be a screwed part, in this screwed part, be screwed into by above the screw that imports of fixedly eyelet and among it, put into spring part.Spring part is flexibly mounted spheroid in slot preferably, and this spheroid can be resisted spring force and be pressed in the slot, and when the end finger bar loosened, spheroid bounce back into a position equally, and end finger self turns to the beginning yarning position by this position.Equally, spring part can be to be fixed on the baffle component or by the fixing leaf spring of baffle component, sheet spring or similar spring.

In addition, solve thus according to the purpose of this utility model, at least one spring part promptly is set on the flier arm, its spring force only as one man affacts in pivot region on the end finger, and in pivot region, the end finger plate is positioned at outside the maximum bobbin circumference.When the end finger plate is held up by the bobbin that twines the biglyyest or during deflection, the spring force of spring part at first affacts on the end finger.In the running status of Speed frames, to end when bobbin is wrapped in the bobbin circumference of way maximum, and can begin automatic bobbin and replace, this end finger plate does not still have spring-load ground and is positioned on the bobbin surface.Take out in order to make in the rotary area of bobbin by flier, end finger must move to for bobbin and pipette suitable position.In addition, the end finger bar works by functional unit, and the spring force of resisting spring part rotates around turning cylinder, and the end finger plate that then is positioned on the bobbin is broken away from by bobbin circumference or bobbin surface.The end finger bar is discharged by functional unit, and the spring force of spring part plays the effect that makes end finger backswing to a position, and in this position, the end finger plate correspondingly abuts on the maximum circumference.Therefore, end finger contacts based on the center of gravity that it is arranged in the end finger bar, and this contact guarantees that end finger turns on the bobbin yarn tube immediately in the beginning spinning process.Simultaneously by realizing that according to flyer spindle machine flier of the present utility model bobbin is not born load by additional end finger pressure unfavourably in winding process.
