Description
Technical field
The present invention relates to the suction nozzle that a kind of station of making the weaving loom of intersected coiled bobbin is used.
Background technology
At the weaving loom of making intersected coiled bobbin (promptly; So-called automatic cross winding machine) on the station; The weaving cop after-combustion that on ring spinner, process and only have a small amount of yarn becomes the doff tube (Auflaufspule) of big volume, and (for example on loom) further processed said doff tube on the weaving loom that is positioned at the technological process downstream subsequently.In the after-combustion process, the yarn defect (Fadenfehler) on the yarn of drawing from the weaving cop is kept watch on, when needing these yarns are cleared up.The station of this automatic cross winding machine has the bobbin bank that is used for keeping rotationally intersected coiled bobbin respectively, be used to drive actuating device that intersected coiled bobbin rotates, the Yarn lateral-movement device of the yarn that arrives intersected coiled bobbin of being used to traverse and the suction nozzle of installing pivotly that can be imposed negative pressure.Suction nozzle be received in after the broken yarn with pneumatic mode or yarn clearer is controllably cut off after, arrive at intersected coiled bobbin surperficial on the yarn loose thread; And it is handed to the Yarn connecting device; At Yarn connecting device place, link together subsequently with yarn on this and from weaving cop yarn under working that extract, that provide by so-called clamp yarn cop.
Widely-used automatic cross winding machine in textile industry, its station all is equipped with so-called thread guide drum.This thread guide drum has realized that simultaneously yarn traverses and the frictional fit formula of intersected coiled bobbin drives; Yet this thread guide drum that has stood test in practice has disadvantage; That is, only can make the intersected coiled bobbin of winding method for " reeling at random " by this thread guide drum.In addition; If when using this thread guide drum, do not adopt complicated addition thereto to guide the loose thread that arrives at; So when broken yarn occurring or after yarn clearer is controllably cut off; The loose thread of cutting off or rupturing at last yarn arrives in those zones on intersected coiled bobbin surface, and situation is uncontrollable.
For this reason, those known suction nozzles all have the sucking hole than broad, that is to say, the inner width of suction nozzle sucking hole approximates the coiling width of intersected coiled bobbin greatly.Although this make through suction nozzle has guaranteed that be the comparison success when suction nozzle is attempted pneumatically to receive from the intersected coiled bobbin surface loose thread and it is handed to the Yarn connecting device, the shortcoming of the suction nozzle of so constructing is than higher consumption of air.
In addition; Some wind2s are also disclosed relatively with automatic cross winding machine; But they are equipped with can be with the bobbin driven roller of single-motor driving and the Yarn lateral-movement device of individual drive, and said Yarn lateral-movement device for example is the finger-type thread-carrier form of installing pivotly.
Not only can produce the intersected coiled bobbin (like the coiling type of " accurately reeling or accurate stepping coiling (
-oder
) ") of various coiling types by these wind2s of for example in DE 198 58 548 A1 or DE 199 60 024 A1, explaining; And causing when reel interrupting controllably cutting off because of yarn clearer, can be scheduled to the yarn loose thread and arrive at the surperficial zone of intersected coiled bobbin through correspondingly controlling the finger-type thread-carrier by this Yarn lateral-movement device.
Summary of the invention
From aforementioned prior art; Task of the present invention is to develop a kind of suction nozzle, and this suction nozzle so constitutes, promptly; Can receive reliably on the one hand and arrive at the surperficial loose thread of intersected coiled bobbin and it is handed to the Yarn connecting device, and the air consumption of this suction nozzle also is reduced on the other hand.
According to the present invention, this task solves through the suction nozzle with the said characteristic of first aspect present invention.
Favourable embodiment of the present invention is the theme of subordinate aspect.
The make that the suction nozzle of cladding system is set in its sucking hole zone according to the present invention especially has the following advantages, and, always can regulate the inner width of the sucking hole of suction nozzle by this cladding system that is with meeting the requirements.This means; When yarn clearer is controllably cut off (this moment, thread-carrier or corresponding Yarn guide device were responsible for making that loose thread arrives at the intersected coiled bobbin surface in predetermined known region); Suction nozzle be flapped toward receive yarn position during cladding system keep shut, so the aspiration ranges of suction nozzle be limited at the intersected coiled bobbin surface, loose thread is arranged in its presumptive area.Cladding system makes the inner width of suction nozzle sucking hole significantly dwindle, and this makes that during the reception yarn after yarn clearer is controllably cut off, the consumption of air of suction nozzle significantly reduces.But after broken yarn, (controllably cut off with yarn clearer and to compare; Broken yarn is more rare incident; And the yarn loose thread does not arrive at the intersected coiled bobbin surface in which zone on when broken yarn, knowing),, just opens suction nozzle cladding system before finally swinging to the reception yarn position in advance.Like this, suction nozzle acts on the intersected coiled bobbin surface along the whole width of intersected coiled bobbin with its sucking hole, and this produces very favourable effect when receiving the loose thread that arrives at unknown mode.Certainly, when yarn clearer is controllably cut off, also can open the cladding system of suction nozzle in principle, for example after yarn clearer is cut off, adopt the cladding system close to attempt receiving after yarn repeatedly all gets nowhere at suction nozzle.
According to a second aspect of the invention, preferably cladding system is configured to the swing lid, it cooperatively interacts with the control stalk that is arranged on the winder station housing regularly during suction nozzle swings to the reception yarn position.Through cladding system being configured to swing the cladding system that lid can be realized reliable operation fairly simplely, and can locate this cladding system reliably all the time when needed.
Yet also can be by special swing lid actuating device (like small-sized electric actuating device or thrust piston formula driving device), the position of adjustment swing lid with meeting the requirements.These actuating devices can be realized at an easy rate, and can the swing lid be navigated to each desired locations reliably.
According to fourth aspect present invention; Stipulate in a favourable embodiment at this; Cladding system can optionally be positioned in the primary importance or be positioned in the second place; Sucking hole is opened fully in said primary importance, and sucking hole can be closed into narrow yarn entering opening in the said second place.In the primary importance of cladding system, guaranteed this moment, be positioned at and preferably arrive at outside the zone, also can receive reliably and arrive at the surperficial loose thread of intersected coiled bobbin even for example broken yarn after, arrive at the loose thread on intersected coiled bobbin surface.Guaranteed that in the second place of cladding system the consumption of air of suction nozzle is limited in indispensable minimum level (unbedingtNotwendige).
According to a fifth aspect of the invention, the swing lid all can be fixed in first and second positions with magnetic means, especially when adjusting the position of said swing lid through control stalk.Through guaranteeing with the fixing swing lid of magnetic means; Cladding system rests on the final position (this cladding system is positioned in this final position through control stalk) of this cladding system all the time; Can realize those best at this final position cladding system and assign the task of giving it, for example: be received in yarn clearer with minimum as far as possible consumption of air and cut off the yarn that arrives at the intersected coiled bobbin surface afterwards in a predefined manner.
In other favourable embodiment; Cladding system is processed by being bent into L shaped cover plate; According to a sixth aspect of the invention, said cover plate has step-like yarn and gets into opening in the zone of short wall part, and the wall part of said weak point can be positioned at before the sucking hole of suction nozzle.
According to a seventh aspect of the invention; Step-like yarn gets into opening to have middle yarn absorption district and is arranged on two yarns entering districts that this yarn is drawn side side, district; Wherein, It is relatively large that middle yarn is drawn the internal height of distinguishing, and the internal height of distinguishing in two yarns entering of side direction is obviously littler.Get into opening through this step-like yarn; Make that on the one hand the consumption of air of suction nozzle is minimized when receiving the loose thread that arrives in a predefined manner; Avoided on the other hand during the yarn that receives is transported to the Yarn connecting device (promptly; When the intersected coiled bobbin unspooling operation traverses to yarn), it is distolateral that received yarn is folded to bobbin too sharp.This means; If intersected coiled bobbin along unreeling direction rotate and unwinding this moment one section yarn; Then after yarn clearer is cut off, draw the yarn of distinguishing reception and may be partial to the yarn entering district that is positioned at side direction through the yarn of centre; This makes and in the zone of cladding system, has significantly reduced maximum bending angle (Abknickwinkel), thereby has protected yarn significantly.
According to the of the present invention the 8th and the 9th aspect; In favourable embodiment; The cladding system of suction nozzle has control and the drive cam that on side direction, protrudes, and said control and drive cam and the guiding device that is arranged on the control stalk on the winder station housing regularly cooperatively interact.This control stalk self has: the guiding profile that can install to finite motion, in order to open the swing lid; And rigidity countermeasure activity (starre Anlaufeinrichtung), in order to close the swing lid.
After yarn clearer is controllably cut off; Suction nozzle is capped at its sucking hole under the situation of device partial closure and directly swings to the reception yarn position; Receive in the yarn position at this; The sucking hole of suction nozzle directly is positioned at before the intersected coiled bobbin surface, and in presumptive area, applies negative pressure to this intersected coiled bobbin surface.Between said shaking peroid, the control and the drive cam that are arranged on the cladding system move below the guiding profile of control stalk, then said guiding profile a little upwards springing some.The cladding system of suction nozzle not only keeps shut in the swing process of suction nozzle, and when pneumatically receiving yarn, also keeps shut.
Which after broken yarn (this moment be known that be not sure of loose thread zone to arrive at the intersected coiled bobbin surface), suction nozzle is positioned to pneumatically receive yarn with the sucking hole of opening fully in.This means that suction nozzle equally at first swings to wherein from its reference position that sucking hole is positioned at the zone of intersected coiled bobbin near surface.At this moment, control and drive cam equally also through some guiding profile below of the upwards springing of control stalk, slip into wherein this control and the drive cam position between the guiding profile of intersected coiled bobbin and control stalk.Again that suction nozzle is moving to backswing subsequently.Said during backswing is moving at suction nozzle; The guiding profile at control stalk slides from the top for control and drive cam; And this control and drive cam are responsible for the swing lid is swung in the position that wherein the suction nozzle sucking hole is opened fully at this, and are locked in this position with magnetic means.
When suction nozzle is swung forwards to when receiving yarn position in order to receive yarn subsequently once more, cladding system rests in this position, before the sucking hole of suction nozzle is positioned at the intersected coiled bobbin surface with preset distance in said reception yarn position.
After receiving yarn, the suction nozzle band the swing that is directed downwards towards the Yarn connecting device of the yarn that captures; At this moment, the control of the cladding system that is opened and drive cam knock the rigidity countermeasure activity of control stalk, and this makes the swing lid be pressed towards wherein the suction nozzle sucking hole once more by in the osed top position as far as possible, and fixes with the mode of magnetic there.

The wind2 of these winder stations 2 (it is totally with Reference numeral 4 expressions) all has bobbin bank 8, and bobbin bank 8 is installing around the mode that pivotal axis 12 moves in limited range.
In this embodiment, the intersected coiled bobbin 5 that in the coiling process, remains in the bobbin bank 8 abuts on the bobbin driven roller 9 with its surface 35 free to rotately, and is driven by it with the mode of frictional fit.In addition; Yarn lateral-movement device 10 traverses between two of intersected coiled bobbin 5 are distolateral and moves to the yarn of intersected coiled bobbin 5 from weaving cop 3 in the coiling process; Wherein, Yarn lateral-movement device 10 has the finger-type thread-carrier 13 that is driven in a predefined manner by electric mechanical actuating device 14.This traverse gear is known, and for example in DE 198 58 548.9, at length it is illustrated.In addition, in the zone at wind2 4 rears, also be provided with intersected coiled bobbin feedway 7, can see Manufactured intersected coiled bobbin off through intersected coiled bobbin feedway 7.
Automatically each winder station 2 of cross winding machine also has suction nozzle of installing pivotly 24 and the clamp yarn cop of installing pivotly 25 respectively; Wherein, Suction nozzle 24 be used to be received in after the broken yarn or controllably being cut off after, arrive at by yarn clearer intersected coiled bobbin 5 surperficial 35 on yarn, and clamp yarn cop 25 is used to provide so-called yarn under working.Suction nozzle 24 installed with the mode that can in limited range, rotate around pivotal axis 23, and suction nozzle 24 can use the actuating device 15 that preferably is constructed to stepper motor, and this actuating device 15 for example is connected on the station computing machine 31 via control path 36.In addition, suction nozzle 24 has cladding system 11, can regulate the inner width of the sucking hole 34 of suction nozzle 24 as required through cladding system 11.
Specify the concrete structure and the function of cladding system below in conjunction with Fig. 2 to Fig. 9.
Can suction nozzle 24 be swung to the reception yarn position from initial position shown in Figure 1 by stepper motor 15, so that receive the yarn that arrives at intersected coiled bobbin 5 surfaces 35; At said reception yarn position place, the sucking hole 34 of suction nozzle 24 keeps preset space length with the surface of intersected coiled bobbin 5 35.
Especially as shown in Figure 3, suction nozzle 24 has sucking hole 34, and its inner width LW approximates the coiling width of intersected coiled bobbin 5 greatly.In addition, suction nozzle 24 has the cladding system of installing pivotly 11, and cladding system 11 can be positioned among position I or the position II, and wherein, I sucking hole 34 is opened (Fig. 3) fully in the position, and II sucking hole 34 parts are closed (Fig. 2) in the position.In position I and position II, cladding system 11 all passes through 44 lockings of permanent magnetism insert in each case.Cladding system 11 mainly comprises the cover plate 37 of L shaped bending, and cover plate 37 part at least is ferromagnetic, and can install with the mode of in limited range, rotating around pivotal axis 16.Control and drive cam 41 that cover plate 37 has the wall part 45 before the sucking hole 34 that can be positioned at suction nozzle 24 and protrudes in side direction.When suction nozzle 24 swings to when receiving yarn position, control and drive cam 41 cooperatively interact with the control stalk 21 that is arranged on the winder station housing 27 regularly, and Fig. 4 shows control stalk 21 and subsequently to its detailed description.
The wall part 45 of cover plate 37 has step-like yarn and gets into opening 38, and the yarn in the middle of this yarn entering opening 38 comprises self is drawn 39 and two in district and is arranged on side other yarn entering district 40A and 40B respectively thereupon.At this, the height that yarn is drawn district 38 is H, and this height H approximates the internal height of the sucking hole 34 of suction nozzle 24 greatly, and to get into the height of distinguishing 40A and 40B be h and be positioned at yarn side by; As shown in the figure, the height h that yarn gets into district 40A and 40B is obviously littler.
Fig. 4 illustrates the control stalk 21 on the winder station housing 27 that is arranged on station 2 regularly.Control stalk 21 has respectively: the guiding profile 42 that is provided with mode that can finite motion, in order to open cladding system 11; And rigidity countermeasure activity 43 (Anlaufeinrichtung), rigidity countermeasure activity 43 be responsible for suction nozzle 21 with the loose thread 51 that is received when Yarn connecting device 26 directions swings is returned, the cladding system of having opened 11 is closed once more.As shown in Figure 4, guiding profile 42 is installed with movable mode by pivotal axis 46, guides the hunting range of profile 42 to be limited stop surface 47,48 at this; With the anti-bonded assembly backstop rollers 49 rotationally of guiding profile 42 against stop surface 47,48.At initial position, as shown in the figure, backstop roller 49 is positioned on the stop surface 47 through the effect of spring element 50).
Below introduce the operation scheme of apparatus of the present invention.
Fig. 5 shows a kind of situation on the winder station, that is, and and the situation after yarn clearer 28 is controllably cut off.The loose thread 51 of last yarn arrives at the surface 35 of intersected coiled bobbin 5 in preset range, wherein, intersected coiled bobbin 5 is installed in rotation in the bobbin bank 8 and is to drive by the mode of bobbin driven roller 9 with frictional fit.Because predetermined yarn arrives at the position that yarn that the position in zone almost is equivalent to the cladding system 11 of suction nozzle 24 is drawn district 39, so suction nozzle 24 mode of closing with cladding system 11 is positioned at it and receives in yarn position.This means that suction nozzle 24 adopts the cladding system (and then under the very low situation of air consumption) of having closed to receive loose thread 51, and loose thread 51 handed to Yarn connecting device 26.
Fig. 6 shows under the similar situation, and this situation appears at after the more rare broken yarn.As shown in the figure, arrive at the surface 35 of the intersected coiled bobbin 5 that remains on rotationally in the bobbin bank 8 at this loose thread 51 with unknown mode (as common after the broken yarn), be in the present embodiment in the scope on intersected coiled bobbin right side).Because the position that yarn arrives at the zone when each broken yarn possibly change, therefore, just opened cladding system 11 suction nozzle 24 being swung to before it receives yarn position.In the position of cladding system shown in Figure 6 11, suction nozzle 24 aspirates intersected coiled bobbin 5 along whole coiling width.This means that even in this case, with the location independent that loose thread arrives at, the loose thread that arrives at is received by suction nozzle 24 and delivered to the possibility of Yarn connecting device still very high.
Fig. 7 is at the suction nozzle of swinging along direction V shown in the lateral plan 24, and wherein, suction nozzle 24 is going in the way that receives yarn position.
The control of cladding system 11 and drive cam 41 be the approaching guiding profile 42 that can install to finite motion from the below; In the ensuing hunting motion process of suction nozzle 24,, will guide profile 42 to press to the top a little with the mode of the power of resisting spring element shown in Figure 4 50.
Looking the type of reel interrupting and decide; Suction nozzle 24 or adopt the cladding system 11 of closing directly to swing to it to receive yarn position (thereby this for example be yarn clearer controllably cut off the situation of reeling and interrupting that causes) is perhaps at first opened cladding system 11 (this for example is to cause the situation of reeling and occurring after interrupting by broken yarn).
After broken yarn; As long as control and drive cam 41 arrive at position and guiding profile 42 before the guiding profile 42 of control stalk 21 and have resetted and (towards its initial position guiding profile 42 is applied effect through spring element 50; Abut on the contact surface 47 at said initial position stopper roller 49), then the actuating device 15 of suction nozzle 24 switches to and returns swing (arrow R).(as shown in Figure 8) in this case, the control of cladding system 11 and drive cam 41 slide above guiding profile 42, and the result is that cladding system 11 is opened and is locked in this position with magnetic means.Finally, suction nozzle 24 swings to it with the cladding system of opening and receives yarn position.
Successfully with pneumatic mode after intersected coiled bobbin 5 surface 35 receives yarn 51, suction nozzle 24 is with the direction swing of the cladding system of closing or opening 11 towards Yarn connecting device 26.
Under the situation that cladding system 11 is closed, the control of cladding system 11 and drive cam 41 at first slide above guiding profile 42, thereby make cladding system 11 be opened.
But that kind as shown in Figure 9, the control of cladding system 11 and drive cam 41 knock the rigidity countermeasure activity 43 of control stalk 21 subsequently at once, and the result is that cladding system 11 is closed at once once more.
If the cladding system 11 of the suction nozzle that is returning 24 is opened, the control of cladding system 11 and drive cam 41 knock the rigidity countermeasure activity 43 of opposing control stalk 21 so.In this case, cladding system 11 also will be closed.
The present invention should not only limit to the embodiment shown in these accompanying drawings.For example, aspect the actuating of cladding system 11, not only can adopt control stalk, and can adopt other devices.For example can adjust the position of cladding system through the respective drive device of electronic or pneumatic work as required.
